Friendship By William Shakespeare s The Merchant Of Venice

Friendship is an idea which spans all cultures, but is expressed differently across cultural boundaries. In William Shakespeare’s The Merchant of Venice, the idea of friendship is critical, not only to the plot, but also for character development. A friend is, â€Å"A person with whom one has developed a close and informal relationship of mutual trust and intimacy; (more generally) a close acquaintance. Often with adjective indicating the closeness of the relationship, asbest, good, close, etc.†(Oxford ) Friendship is the display of trust and intimacy as well as caring for one another. Antonio and Bassanio are the best of friends. Although both Antonio and Bassanio’s characters possess different motivations for their actions, it is their strong†¦show more content†¦However, it can be seen that Bassanio does feel guilt over his actions. â€Å"To you, Antonio, I owe the most, in money and in love† (I, I, 177-178). Bassanio is expressing his remorse over having lived a lifestyle far beyond that which with his wealth permits, but is grateful for the support that Antonio has provided him. Although Bassanio may use Antonio for his coffers, he also owes Antonio in love. This in turn displays that camaraderie is important to Bassanio and although he may be careless with his money, he is a loyal and caring individual. However, it is clear that at the beginning of the play, Antonio is far more invested in Bassanio than Bassanio is Antonio. At the beginning of the play it appears that although they may be genuine friends, Bassanio may be using Antonio for his generosity rather than brotherhood. Their friendships and characters are further expanded upon when Antonio goes to meet Shylock and settle the terms of Bassanio’s loan. Act I, Scene 3 is arguably the most important scene in The Merchant of Venice. As it not only sets up the development of the plot but also furthers the development of Antonio and Bassanio’s friendship. In this scene, Antonio and Bassanio meet with Shylock to discuss terms of a loan that Bassanio may use to attempt to pursue Portia. Instead of having to pay usury, Shylock opts to take a pound of Antonio’s flesh if the debt is paid late. Upon hearing this, Antonio is confident that he

Essay about Bloody Queen Mary Whats in a Name - 1072 Words

Nicknames are generally defined as subterfuge given to a person to better understand their personalities. In order to understand whether Queen Mary deserves her nickname we must first look at her history. Mary I of England was born on February 18th 1516. She was the only surviving child of Henry VIII’s first wife, Catherine of Aragon. Due to her gender and her mother’s incapability to produce a male heir, they were both cast away. It was after the death of Edward VI in which Mary made a bid for her birthright as heir to the throne. Edward VI and his council intended for his cousin Lady Jane Grey to succeed him because of her protestant faith. However, after only nine days Jane Grey was dethroned by Mary by popular support. During her reign†¦show more content†¦One would argue that this was a book simply retelling of the burnings that were in fact ordered by Queen Mary. Therefore, the nickname Bloody Queen Mary would be appropriate. This is a strange assumption because monarchs have ordered the deaths of people long before Mary even existed. William the Conqueror’s army killed around 5000 Anglo-Saxons during the battle of Hastings. This staggering number is almost 16 times larger than the 283 Protestants Mary had executed. However, one would argue that the Battle of Hastings was in fact a battle. Its death tolls could not possibly be compared to the Protestants who were burned during Mary’s reign. However, here the lies the real question. What is so different between those who were slaughtered during a battle and those who were slaughtered during peacetime? In both circumstances, the head of the state was doing what they thought best for their country. William wished to expand Normandy’s borders and Queen Mary wanted to restore England to the Roman Catholic church so that England would be spiritually restored in the eyes of God. Although William had around 5000 people butchered by his men in one day, it is Queen Mary t hat earns such a disgraceful nickname for having only 283 Protestants burned. The reason for this is simple; Queen Mary was succeeded by a protestant. If it were a Catholic who succeeded Mary, there would not be a Bloody Queen Mary.

Mineral Particles Derived From Rocks Environmental Sciences Essay Free Essays

Chapter 2 LITERATURE REVIEW 2.1. Introduction Dirts are composed of five chief constituents ( Sinha and Shrivastava, 2000 ) : mineral atoms derived from stones by enduring ; organic stuffs – humus from dead and disintegrating works stuff ; dirt H2O – in which alimentary elements are dissolved ; dirt air – both C dioxide and O ; and populating beings including bacteriums that help works decomposition. We will write a custom essay sample on Mineral Particles Derived From Rocks Environmental Sciences Essay or any similar topic only for you Order Now Soils differ in their birthrate degrees, because they have different proportions of these constituents and because the mineral atoms have been affected to different grades by enduring. Age of dirt minerals, predominating temperatures, rainfall, leaching and dirty physico-chemistry are the chief factors which determine how much a peculiar dirt will endure ( Sinha and Shrivastava, 2000 ) . Soil therefore, is of import to everyone either straight or indirectly. It is the natural organic structures on which agricultural merchandises grow and it has delicate ecosystem ( Sinha and Shrivastava, 2000 ) . South Africa ranks among the states with the highest rate of income inequality in the universe ( Aliber, 2009 ) . Compared to other in-between income states, it has highly high degrees of absolute poorness and nutrient insecurity menace ( FAO, 2009 ) . As portion of this, a possible subscriber to nutrient security might be small-scale agricultural production. Aliber ( 2009 ) indicated that input support aiming smallholder husbandmans could hike production and nutrient security. Use of uncultivated cultivable lands and subsistence agribusiness might be one option to lend to incomes and/or nest eggs, every bit good as to promote nutrient variegation ( Altman et al. , 2009 ) . Land with high agricultural suitableness is considered to hold greater long-run security with respects to both agricultural production and development. From a planning position, high agricultural flexibleness is hence considered an appropriate step of high quality agricultural land that is extremely productive and fertile. Merely a little proportion of universe ‘s dirts have a really good degree of birthrate, most of which have merely good to medium birthrate and some have really low birthrate, and are frequently referred to as fringy dirts ( Ashman and Puri, 2002 ) . Well-known fertile dirts are deep alluvial dirts formed from river clay, organic matter- rich dirts on loess stuff, alimentary rich Vertisols and volcanic dirts ( Brady and Weil, 2004 ) . Under hapless direction, dirt birthrate can be earnestly depleted and dirts may go useless for agribusiness. 2.2. SOIL PHYSICO-CHEMISTRY Soil is a natural medium on which agricultural merchandises grow and it is dependent on several factors such as birthrate to be considered productive ( Shah et al. , 2011 ) . The birthrate of the dirt is depended on concentration of dirt foods, organic and inorganic stuffs and H2O. These soil physico-chemical belongingss are classified as being physical, chemical and biological, which greatly influence dirt birthrate ( Ramaru et al. , 2000 ) . To pull off dirt birthrate, cognition and apprehension of these belongingss is required ( as discussed below ) . 2.2.1. Physical dirt belongingss ( I ) Dirt texture Soil texture refers to the comparative proportions of the assorted size groups of single atoms or grains in a dirt ( Rowell, 1994 ) . It is dependent on the mixture of the different atom sizes present in the dirt. Based on these different sizes, dirt atoms are classified as sand ( 0.05- 2mm ) , silt ( 0.002-0,5mm ) and clay ( lt ; 0,002mm ) ( Rowell, 1994 ) . Soil texture is arguably the individual most of import physical belongings of the dirt in footings of dirt birthrate, because it influences several other dirt belongingss including denseness, porousness, H2O and alimentary keeping, rate of organic affair decomposition, infiltration and cation exchange capacity ( Moberg et al. , 1999 ) . Clay particles keep larger measures of H2O and foods, because of their big surface countries ( Brady and Weil, 1999 ) . This belongings causes the puffiness and shrinkage of clay dirts, but merely those with smectitic group of clay minerals. The big surface country of clay atoms gives foods legion adhering sites particularly when the surface charge denseness is high, which is portion of the ground that mulct textured dirts have such high abilities to retain foods ( Velde, 1995 ) . The pores between clay atoms are really little and complex, so motion of both air and H2O is really slow ( Brady and Weil, 1999 ) . Clay atoms are negatively charged because of their mineralogical composing. Dirts with such atoms normally have high CEC and can retain H2O and works foods ; therefore such dirts are considered to be fertile and good for works growing ( Brady and Weil, 1999 ) . The cognition of the proportions of different-sized atoms in dirts is critical to understand dirt behaviour and their direction. Since sand atoms are comparatively big, so are the nothingnesss between them, which promote free drainage of H2O and entry of air into the dirt ( Brady and Weil, 2002 ) . The deduction of free drainage in flaxen dirt is that dirt foods are easy washed down into the dirt and go unaccessible for usage by workss ( Brady and Weil, 2002 ) . Sandy dirts are considered non-cohesive and because of their big size, have low specific surface countries and therefore have low alimentary keeping capacity ( Rowell, 1994 ) . Sand atoms can keep small H2O due to low specific surface country and are prone to drought, hence have a really low CEC and birthrate position ( Petersen et al. , 1996 ) . The pores between silt atoms are much smaller than those in sand, so silt retains more H2O and foods ( Rowell, 1994 ) . Soils dominated by silt atoms hence have a higher birthrate position than sandy dirts and provides favourable conditions for works growing when other growing factors are favourable ( Miller and Donahue, 1992 ) . ( two ) Dirt construction The term dirt construction refers to the agreement of dirt atoms into sums ( Six et al. , 2000 ) . Dirt construction is affected by biological activities, organic affair, and cultivation patterns ( Rowell, 1994 ) . It influences soil H2O motion and keeping, eroding, alimentary recycling, sealing and crusting of the dirt surface, together with aeration and dirt ‘s structural stableness, root incursion and harvest output ( Lupwayi et al. , 2001 ) . Dirt construction can be platy, prismatic, farinaceous, crumbly, columnar and blocky ( RCEP, 1996 ) . An ideal dirt construction for works growing is frequently described as farinaceous or crumb-like, because it provides good motion for air and H2O through a assortment of different pore sizes and it besides affects root incursion ( RCEP, 1996 ) . An ideal dirt construction is besides stable and immune to eroding ( Duiker et al. , 2003 ) . Organic affair and humification procedures improve structural stableness, and can reconstruct debauched dirt constructions ( Brady and Weil, 1999 ) . Therefore it is critical to return or add organic stuff to the dirt and to keep its biological activity in order to heighten dirt construction for works growing. Favorable dirt construction and high sum stableness are hence critical to bettering dirt birthrate, increasing agronomic productiveness, heightening porousness and diminishing erodibility. ( three ) Water keeping capacity Water keeping capacity refers to the measure of H2O that the dirt is capable of hive awaying for usage by workss ( Brady and Weil, 1999 ) . Soil H2O is held in, and flows through pore infinites in dirts. Soil H2O can be described into the undermentioned phases: gravitational, capillary, and hygroscopic, based upon the energy with which H2O is held by the dirt solids, which in bend governs their behaviour and handiness to workss ( Rowell, 1994 ) . Water keeping capacity is an of import factor in the pick of workss or harvests to be grown and in the design and direction of irrigation systems ( Brady and Weil, 1999 ) . The entire sum of H2O available to workss turning in field dirts is a map of the rooting deepness of the works and amount of the H2O held between field capacity and wilting per centum in each of the skylines explored by the roots ( Brady and Weil, 1999 ) . Field capacity is the sum of dirt wet or H2O content held in dirt after extra H2O has drained off and the rate of downward motion has materially decreased, which normally takes topographic point within 2-3 yearss after a rain or irrigation in pervious dirts of unvarying construction and texture ( Govers, 2002 ) . The ability of the dirt to supply H2O for workss is an of import birthrate characteristic ( RCEP, 1996 ) . The capacity for H2O storage varies, depending on dirt belongingss such as organic affair, dirt texture, bulk denseness, and dirt construction ( RCEP, 1996 ) . This is explained by the grade of dirt compression, where jobs will originate if inordinate compression occurs which would consequences in increased majority denseness, a lessening in porousness and aeration and hapless H2O drainage ( Gregory et al. , 2006 ) , all ensuing in hapless works growing. ( four ) Electrical Conductivity ( EC ) Soil electrical conduction ( EC ) , is the ability of dirt to carry on electrical current ( Doerge, 1999 ) . EC is expressed in milliSiemens per metre ( mS/m ) or centimeter ( cm/m ) . Traditionally, dirt scientists used EC to gauge dirt salt ( Doerge, 1999 ) . EC measurings besides have the potency for gauging fluctuation in some of the dirt physical belongingss such as dirt wet and porousness, in a field where dirt salt is non a job ( Farahani and Buchleiter, 2004 ) . Soil salt refers to the presence of major dissolved inorganic solutes in the dirt aqueous stage, which consist of soluble and readily dissoluble salts including charged species ( e.g. , Na+ , K+ , Mg+2, Ca+2, Cla?’ , HCO3a?’ , NO3a?’ , SO4a?’2 and CO3a?’2 ) , non-ionic solutes, and ions that combine to organize ion braces ( Smith and Doran, 1996 ) . Salt tolerances are normally given in footings of the phase of works growing over a scope of electrical conduction ( EC ) degrees. EC greater than 4dS/m are considered saline ( Munshower, 1994 ) . Salt sensitive workss may be affected by conductions below 4dS/m and salt tolerant species may non be impacted by concentrations of up to twice this maximal agricultural tolerance bound ( Munshower, 1994 ) . Electrical conduction is the ability of a solution to convey an electrical current. The conductivity of electricity in dirt takes topographic point through the moisture-filled pores that occur between single dirt atoms. Therefore, the EC of dirt is determined by the undermentioned dirt belongingss ( Doerge, 1999 ) : . Porosity, where the greater dirt porousness, the more easy electricity is conducted. Soil with high clay content has higher porousness than sandier dirt. Compaction usually increases dirt EC. . Water content, dry dirt is much lower in conduction than damp dirt. . Salinity degree, increasing concentration of electrolytes ( salts ) in dirt H2O will dramatically increase dirt EC. . Cation exchange capacity ( CEC ) , mineral dirt incorporating high degrees of organic affair ( humus ) and/or 2:1 clay minerals such as montmorillonite, illite, or vermiculite hold a much higher ability to retain positively charged ions ( such as Ca, Mg, K, Na, NH4, or H ) than dirt missing these components. The presence of these ions in the moisture-filled dirt pores will heighten dirt EC in the same manner that salt does. . Temperature, as temperature decreases toward the stop deading point of H2O, dirt EC decreases somewhat. Below freeze, dirt pores become progressively insulated from each other and overall dirt EC declines quickly. Plants are harmfully affected, both physically and chemically, by extra salts in some dirts and by high degrees of exchangeable Na in others. Dirty with an accretion of exchangeable Na are frequently characterized by hapless tilth and low permeableness and hence low dirt birthrate position, doing them unfavourable for works growing ( Munshower, 1994 ) . ( V ) Bulk Density ( BD ) Soil majority denseness is defined as the mass of dry dirt ( g ) per unit volume ( cm3 ) and is routinely used as a step of dirt compression ( Gregory et al. , 2006 ) . The entire volume includes atom volume, inter-particle nothingness volume and internal pore volume ( Gregory et al. , 2006 ) . Bulk denseness takes into history solid infinite every bit good as pore infinite ( Greenland, 1998 ) . Therefore soils that are porous or well-aggregated ( e.g. clay dirt ) will hold lower majority densenesss than dirts that are non aggregated ( sand ) ( Greenland, 1998 ) . Plant roots can non perforate compacted dirt every bit freely as they would in non-compacted dirt, which limits their entree to H2O and foods present in sub-soil and inhibits their growing ( Hagan et al. , 2010 ) . Compacted dirt requires more frequent applications of irrigation and fertiliser to prolong works growing, which can increase overflow and food degrees in overflow ( Gregory et al. , 2006 ) . The majority denseness of dirt depends greatly on the dirt ‘s mineral make up and the grade of compression. High bulk denseness normally indicate a poorer environment for root growing, reduced aeration and unwanted alterations in hydrologic map, such as decreased infiltration ( Brady and Weil, 1999 ) . The presence of dirt organic affair, which is well lighter than mineral dirt, can assist diminish bulk denseness and thereby heightening dirt birthrate ( Hagan et al. , 2010 ) . 2.2.2. Soil Chemical belongingss Soil chemical belongingss which include the concentrations of foods, cations, anions, ion exchange reactions and oxidation-reduction belongingss, but for the intent of this survey focal point will be based on belongingss that have an deduction on dirt birthrate including: ( I ) Soil pH Soil pH is an of import dirt belongings that affects several dirt reactions and procedures and is defined as a step of the sourness or alkalinity of the dirt ( Bohn, 2001 ) . It has considerable consequence on dirt procedures including ion exchange reactions and alimentary handiness ( Rowell, 1994 ) . Soil pH is measured on a graduated table of 0 to 14, where a pH of 7.0 is considered impersonal, readings higher than 7.0 are alkalic, and readings lower than 7.0 are considered acidic ( McGuiness, 1993 ) . Most workss are tolerant of a pH scope of 5.5-6.5 which is near impersonal pH scope ( Bohn, 2001 ) . Soil pH is one of the most of import features of dirt birthrate, because it has a direct impact on alimentary handiness and works growing. Most foods are more soluble in acid dirts than in impersonal or somewhat alkalic dirts ( Bohn, 2001 ) . In strongly acidic soils the handiness of macronutrients ( Ca, Mg, K, P, N and S ) every bit good as Mo and B is reduced. In contrast, handiness of micronutrient cations ( Fe, Mn, Zn, Cu and Al ) is increased by low dirt pH, even to the extent of toxicity of higher workss and micro-organisms ( Bohn, 2001 ) . The pH of a dirt is besides reported to impact so many other dirt belongingss ( Brady and Weil, 1999 ) , including alimentary handiness, effects on dirt beings, Fungis thrive in acidic dirts, CEC and works penchants of either acidic or alkalic dirts. Most workss prefer alkaline dirts, but there are a few which need acidic dirts and will decease if placed in an alkaline environment ( Brady and Weil, 1999 ) . ( two ) Cation Exchange Capacity ( CEC ) Cation exchange capacity is defined as the amount of the sum of the exchangeable cations that a dirt can keep or adsorb ( Brady and Weil, 1999 ) . A cation is a positively charged ion and most foods cations are: Ca2+ , Mg2+ , K + , NH4+ , Zn2+ , Cu2+ , and Mn2+ . These cations are in the dirt solution and are in dynamic equilibrium with the cations adsorbed on the surface of clay and organic affair ( Brady and Weil, 1999 ) . Clay and organic affair are the chief beginnings of CEC ( Peinemann et al. , 2002 ) . The more clay and organic affair ( humus ) a dirt contains, the higher its CEC and the greater the possible birthrate of that dirt. CEC varies harmonizing to the type of clay. It is highest in montmorillonite clay, lowest in to a great extent weathered kaolinite clay and somewhat higher in the lupus erythematosus weathered illite clay ( Peinemann et al. , 2002 ) . Sand atoms have no capacity to interchange cations because it has no electrical charge ( Brady and Weil, 1999 ) . CEC is used as a step of dirt alimentary keeping capacity, and the capacity to protect groundwater from cation taint ( Brady and Weil, 1999 ) . It buffers fluctuations in alimentary handiness and dirt pH ( Bergaya and Vayer, 1997 ) . Plants obtain many of their foods from dirt by an electrochemical procedure called cation exchange. This procedure is the key to understanding dirt birthrate ( Rowell, 1994 ) . Foods that are held by charges on a dirt are termed ‘exchangeable ‘ as they become readily available to workss ( Rowell, 1994 ) .The higher the CEC of a dirt, the more foods it is likely to keep and the higher will be its birthrate degree ( Fullen and Catt, 2004 ) . Factors impacting cation exchange capacity The factors impacting cation exchange capacity include the undermentioned ( Brady and Weil 1999 ) , dirt texture, dirt humus content, nature of clay and dirt reaction. Soil texture influences the CEC of dirts in a manner that it increases when dirt ‘s per centum of clay additions i.e. the finer the dirt texture, the higher the CEC as indicated in Table 2. CEC depends on the nature of clay minerals present, since each mineral has its ain capacity to exchange and keep cations e.g. the CEC of a dirt dominated by vermiculite is much higher than the CEC of another dirt dominated by kaolinite, as vermiculite is high activity clay unlike kaolinte which is low activity clay. When the pH of dirt additions, more H+ ions dissociate from the clay minerals particularly kaolinite, therefore the CEC of dirt dominated by kaolinite besides increases. CEC varies harmonizing to the type of dirt. Humus, the terminal merchandise of decomposed organic affair, has the highest CEC value because organic affair colloids have big measures of negative charges. Humus has a CEC two to five times greater than montmorillonite clay and up to 30 times greater than kaolinite c lay, so is really of import in bettering dirt birthrate. Table 2.1: CEC values for different dirt textures ( Brady and Weil, 1999 ) Dirt texture CEC scope ( meq/100g dirt ) Sand 2-4 Sandy loam 2-12 Loam 7-16 Silt loam 9-26 Clay, clay loam 4-60 ( three ) Organic Matter The importance of dirt organic affair in relation to dirty birthrate and physical status is widely recognized in agribusiness. However, organic affair contributes to the birthrate or productiveness of the dirt through its positive effects on the physical, chemical and biological belongingss of the dirt ( Rowell, 1994 ) , as follows: physical – stabilizes dirt construction, improves H2O keeping features, lowers bulk denseness, dark colour may change thermic belongingss ; chemical – higher CEC, acts as a pH buffer, ties up metals, interacts with biological – supplies energy and body-building components for dirt beings, increases microbic populations and their activities, beginning and sink for foods, ecosystem resiliency, affects dirt enzymes. Soil organic affair consists of a broad scope of organic substances, including populating beings, carboneous remains of beings which one time occupied the dirt, and organic compounds produced by current and past metamorphosis of the dirt ( Brady and Weil, 1999 ) . Soil organic affair plays a critical function in dirt procedures and is a cardinal component of incorporate dirt birthrate direction ( ISFM ) ( Brady and Weil, 2004 ) . Organic affair is widely considered to be the individual most of import index of dirt birthrate and productiveness ( Rowell, 1994 ) . It consists chiefly of decayed or disintegrating works and animate being residues and is a really of import dirt constituent. Benefits of Organic affair in dirt harmonizing to Ashman and Puri, ( 2002 ) include: increasing the dirt ‘s cation exchange capacity and moving as nutrient for dirt beings from bacteriums to worms and is an of import constituent in the food and C rhythms. Organic affair, like clay, has a high surface country and is negatively charged with a high CEC, doing it an first-class provider of foods to workss. In add-on, as organic affair decomposes, it releases foods such as N, P and S that are bound in the organic affair ‘s construction, basically copying a slow release fertiliser ( Myers, 1995 ) . Organic affair can besides keep big sums of H2O, which helps foods move from dirt to works roots ( Mikkuta, 2004 ) . An of import feature of organic affair in dirt birthrate is C: N ratio. The C: N ratio in organic affair of cultivable surface skylines normally ranges from 8:1 to 15:1, the average being near 12:1 ( Brady and Weil, 1999 ) . The C: N ratio in organic residues applied to dirts is of import for two grounds: intense competition among the microorganisms for available dirt N which occurs when residues holding a high Degree centigrade: N ratio are added to dirts and it besides helps find their rate of decay and the rate at which N is made available to workss ( Brady and Weil, 1999 ) . ( four ) Plant Foods Plants require 13 works foods ( Table 2.2 ) ( micro and macro foods ) for their growing. Each is every bit of import to the works, yet each is required in immensely different sums ( Ronen, 2007 ) . Essential elements are chemical elements that workss need in order to finish their normal life rhythm ( Scoones and Toulhim, 1998 ) . The maps of these elements in the works can non be fulfilled by another, therefore doing each component necessity for works growing and development ( Scoones and Toulhim, 1998 ) . Essential foods are divided into macro and micronutrients as illustrated in Table 3. Macronutrients are those that are required in comparatively high measures for works growing and can be distinguish into two bomber groups, primary and secondary 1s, ( Uchida and Silva, 2000 ) . The primary macro-elements are most often required for works growing and besides needed in the greatest entire measure by workss. For most harvests, secondary macro foods are needed in lesser sums than the primary foods. The 2nd group of works foods which are micronutrients are needed merely in hint sums ( Scoones and Toulhim, 1998 ) . These micronutrients are required in really little sums, but they are merely every bit of import to works development and profitable harvest production as the major foods ( Ronen, 2007 ) . Categorization Component Function in works growing Beginning Lack symptoms and toxicities Macro foods – Primary Nitrogen ( N ) Chlorophyll and Protein formation Air/Soil, applied fertilizers Slow growing, stunted workss, greensickness, low protein content Phosphorus ( P ) Photosynthesis, Stimulates early growing and root formation, hastens adulthood Dirt and applied fertilizers Slow growing, delayed harvest adulthood, purple green colour of foliages Potassium ( K ) Photosynthesis and nzyme activity, amylum and sugar formation, root growing Dirt and applied fertilizers Slow growing, Reduced disease or plague opposition, development of white and xanthous musca volitanss on foliages Macro foods – secondary Calcium ( Ca ) Cell growing and constituent of cell wall Dirt Weakened roots, decease of workss ‘ turning points, unnatural dark green visual aspect on leaf Magnesium ( Mg ) Enzyme activation, photosynthesis and influence Nitrogen metamorphosis Dirt Interveinal greensickness in older foliages, curling of foliages, stunted growing, Sulfur ( S ) Amino acids, proteins and nodule formation Dirt and carnal manure Interveinal greensickness on maize foliages, retarded growing, delayed adulthood and visible radiation viridities to yellowish colour in immature foliages Micronutrients – necessity Iron ( Fe ) Photosynthesis, chlorophyll synthesis, component of assorted enzymes and proteins Dirt Interveinal greensickness, yellowing of foliages between venas, twig dieback, decease of full hitch or workss Manganese ( Mn ) Enzyme activation, metamorphosis of N and organic acids, formation of vitamins and dislocation of saccharides Dirt Interveinal greensickness of immature foliages, step of picket green colour with darker colour next to venas Zinc ( Zn ) Enzymes and auxins constituent, protein synthesis, used in formation of growing endocrines Dirt Mottled foliages, dieback branchlets, lessening in root length Copper ( Cu ) Enzyme activation, accelerator for respiration Dirt Scrawny growing, hapless pigmentation, wilting of foliages Boron ( B ) Reproduction Dirt Thickened, curled, wilted and greensick foliages ; reduced blossoming Molybdenum ( Mo ) Nitrogen arrested development ; nitrate decrease and works growing Dirt Stunting and deficiency of energy ( induced by nitrogen lack ) , searing, cupping or turn overing of foliages Chlorine ( Cl ) Root growing, photosynthetic reactions Dirt Wilting followed by greensickness, inordinate ramification of sidelong roots, bronzing of foliages Extra foods Carbon ( C ) Component of saccharides and photosynthesis Air/ Organic affair Hydrogen ( H ) Maintains osmotic balance and component of saccharides Water/Organic affair Oxygen ( O ) Component of saccharides and necessary for respiration Air/Water/ Organic affair Table 2.2: Essential works elements, their beginnings and function in workss ( Ronen,2007 ) Lack of any of these indispensable foods will retard works development ( Brady and Weil, 2004 ) . Deficiencies and toxicities of foods in dirt present unfavourable conditions for works growing, such as: hapless growing, yellowing of the foliages and perchance the decease of the works as illustrated in Table 3 ( Ahmed et al. , 1997 ) . Therefore proper alimentary direction is required to accomplish upper limit works growing, maximal economic and growing response by the harvest, and besides for minimal environmental impact. In add-on to the foods listed supra, workss require C, H, and O, which are extracted from air and H2O to do up the majority of works weight ( Brady and Weil, 1999 ) . Achieving balance between the alimentary demands of workss and the alimentary militias in dirts is indispensable for keeping dirt birthrate and high outputs, forestalling environmental taint and debasement, and prolonging agricultural production over the long term. 2.2.3. Soil Biological belongingss ( I ) Soil beings Soil beings include largely microscopic populating beings such as bacteriums and Fungis which are the foundation of a healthy dirt because they are the primary decomposer of organic affair ( Brady and Weil, 1999 ) . Soil beings are grouped into two viz. soil micro-organisms and dirt macro beings ( Table 2.3 ) . Table 2.3: Dirt Macro and micro-organisms and their function in works and dirt ( Brady and Weil, 1999 ) Categorization Organisms Function in works and/or dirt Beginning Microorganisms Bacterias Decomposition of organic affair Soil surface and humus atoms Actinomycetes Beginning of protein and enhance dirt birthrate Surface beds of grass lands Fungus kingdoms Fix atmospheric N and enhance dirt birthrate Soil ( without organic affair ) Alga Add organic affair to dirty, better aeration of swamp dirts, and repair atmospheric N Moist dirts Macro-organisms Nematodes They can be applied to harvests in big measures as a biological insect powder Dirt and works roots Earthworms Enhance dirt birthrate and structural stableness Aerated dirts Ants and white ants Soil development Dominant in tropical dirts Dirt can incorporate 1000000s of beings that feed off disintegrating stuff such as old works stuff, mulch A ; unrefined compost ( Ashman and Puri, 2002 ) , Microorganisms constitute lt ; 0.5 % of the dirt mass yet they have a major impact on dirt belongingss and procedures. 60-80 % of the entire dirt metamorphosis is due to the microflora ( Alam, 2001 ) . Micro-organisms, including Fungis and bacteriums, affect chemical exchanges between roots and dirt and act as modesty of dirt foods ( Kiem and Kandeler, 1997 ) . Soil organic affair is the chief nutrient and energy beginning of dirt micro-organisms ( Ashman and Puri, 2002 ) . Through decomposition of organic affair, micro-organisms take up their nutrient elements. Organic affair besides serves as a beginning of energy for both macro and micro beings and helps in executing assorted good maps in dirt, ensuing in extremely productive dirt ( Mikutta et al. , 2004 ) . Macro-organisms such as insects, other arthropods, angleworms and roundworms live in the dirt and have an of import influence on dirt birthrate ( Amezketa, 1999 ) . They ingest soil stuff and relocate works stuff and signifier tunnels. The effects of these activities are variable. Macro-organisms improve aeration, porousness, infiltration, aggregative stableness, litter commixture, improved N and C stabilisation, C turnover and carbonate decrease and N mineralization, alimentary handiness and metal mobility ( Amezketa, 1999 ; Winsome and McColl, 1998 and Brown et al. , 2000 ) . The assorted groups of dirt beings do non populate independently of each other, but form an interlocked system more or less in equilibrium with the environment ( Brady and Weil, 1999 ) . Their activity in dirt depend on wet content, temperature, dirt enzymes, disintegration of dirt minerals and dislocation of toxic chemicals. All have a enormous function in the development of dirt birthrate ( Alam, 2001 ) . Their actions involve the formation of structural systems of the dirts which help in the addition of agricultural productiveness ( Alam, 2001 ) . 2.3. SOIL CLAY MINERALOGY The clay fraction of dirt is dominated by clay minerals which control of import dirt chemical belongingss including sorption features of dirts ( Dixon and Schulze, 2002 ) . Minerals are of course happening inorganic compounds, with defined chemical and physical belongingss ( Velde, 1995 ) . Minerals that are formed in the deepnesss of a vent are called primary minerals ( Pal et al. , 2000 ) . Feldspar, biotite, vitreous silica and hornblende are illustrations of primary minerals. These minerals and the stones made from them are frequently non stable when exposed to the weathering agents at the surface of the Earth ( Dixon and Schulze, 2002 ) . These stones are broken down ( weathered ) continuously into little pieces by exposure to physical and chemical weathering procedures ( Dixon and Schulze, 2002 ) . Some of the elements that are released during weathering, reform and crystallise in a different construction organizing secondary minerals ( Melo et al. , 2002 ) . Secondary minerals tend to be much smaller in atom size than primary minerals, and are most normally found in the clay fraction of dirts ( Guggenheim and Martin, 1995 ) . Soil clay fractions frequently contain a broad scope of secondary minerals such as kaolinite, montmorillonite and aluminium hydrated oxides, whereas the sand or silt atoms of dirts are dominated by comparatively inert primary minerals. The clay fraction is normally dominated by secondary minerals which are more chemically active and lend the most to dirty birthrate ( Melo et al. , 2002 ) . Two major secondary mineral groups, clay minerals and hydrated oxides, tend to rule. These groups can look in assorted mixtures frequently in association with dirt organic affair ( Brady and Weil, 2004 ) . Clay minerals are hydrated aluminum phyllosilicates, sometimes with variable sums of Fe, Mg, alkali metals, alkalic Earth metals and other cations, ( Joussein et al. , 2005 ) . They are derived from enduring of stones and are really common in all right grained sedimentary stones such as shale, mudstone and siltstone and in all right grained metamorphous slate and phyllite ( Van der Merwe et al. , 2002 ) . There are besides non-clay minerals such as vitreous silica and calcite which are derived from enduring of pyrogenic stones, ( Van der Merwe et al. , 2002 ) . Clay minerals are indispensable stages in dirt chemical science and play highly of import functions in ion exchange reactions ( Brigatti et al. , 1996 ; Barrow, 1999 ) . Soils which are texturally and chemically similar may differ in productiveness or birthrate due to the presence or absence of little sums of peculiar clay minerals ( Van der Merwe et al. , 2002 ) . For illustration, smectite clays are various and strong cationic money changers and their presence can greatly act upon the mobility of potentially toxic elements. Vermiculite has been widely used in the survey of short- to medium-term fluctuations ( seasonal and one-year ) in dirt procedures ( Monterroso and Macias, 1998 ) . Soil clay mineralogy plays a critical function in dirt birthrate since mineral surfaces serve as possible sites for alimentary storage ( Tucker, 1999 ) . However, different types of dirt minerals hold and retain differing sums of foods ( Velde, 1995 ) . Therefore, it is critical to cognize the types of minerals that make up a dirt so as to foretell the grade to which the dirt can retain and provide foods to workss. Knowledge of the clay mineralogical composing and the different clay minerals present in dirt is of import in understanding usage, and direction of the dirt, and in finding the agricultural potencies of dirts. 2.3.1. Happening of clay and clay minerals Claies and clay minerals occur under a reasonably limited scope of geologic conditions ( Velde et al. , 2003 ) . The environments of formation include dirt skylines, Continental and marine deposits, geothermic Fieldss, volcanic sedimentations, and enduring stone formations ( Joussein et al. , 2005 ) . Most clay minerals form where stones are in contact with H2O, air, or steam ( Hillier, 1995 ) . Examples of these state of affairss include enduring bowlders on a hillside, deposits in sea or lake undersides, profoundly inhumed deposits incorporating pure H2O, and stones in contact with H2O heated by magma ( liquefied stone ) ( Hillier, 1995 ) . A primary demand for the formation of clay minerals is the presence of H2O. Soil clay minerals ‘ formation occurs in many different environments, including the weathering environment, the sedimentary environment, and the digenetic-hydrothermal environment ( Brady and Weil, 1999 ) . Clay minerals composed of the more soluble compounds e.g. smectites are formed in environments where ions can roll up ( e.g. in a dry clime, in a ill drained dirt, in the ocean, or in saline lakes ) ( Velde 1995 ) . Clay minerals composed of less soluble compounds ( for illustration, kaolinite and halloysite ) signifier in more dilute H2O such as that found in environments that undergo terrible leaching ( for illustration, a brow in the wet Torrid Zones ) , where merely meagerly soluble elements such as aluminium and Si can stay ( Brady and Weil, 1999 ) . Illite and chlorite are known to organize copiously in the diagenetic-hydrothermal environment by reaction from smectite ( Brady and Weil, 1999 ) . 2.3.2. Weathering of minerals The minerals ‘ parent stuffs form in the crystallization of liquefied stone stuff: these are known as primary minerals, and include olivine, quartz, feldspar and hornblende. Primary minerals are non stable when exposed to H2O, air current and extremes of temperature ( Hillier, 1995 ) . Some of the elements that are released during enduring reform and crystallise in a different construction: these are the secondary minerals, and include vermiculite, montmorillonite and kaolinite ( Hillier, 1995 ) . Secondary minerals tend to be much smaller in atom size than primary minerals, and are most normally found in the clay fraction of dirts. As minerals weather, they lose Si ( as soluble silicic acid ) , taking to increasing proportions of aluminates in weather-beaten clays, such as kaolinite. Aluminium hydrated oxide species are amphoteric. The rate and nature of the enduring procedure really much depends on climatic conditions. Intense enduring produced in a hot and damp clime can take to major alterations in mineral construction and the transition to hydrated oxides. There are four stages to be considered in the system that model the formation of clay minerals by the weathering of flinty stones as the clays have a definite composing: K-feldspar, Muscovite ( illite ) , Kaolinite and gibbsite: 3KAlSi3O8 ) +2H+ +12H2O i‚ «2K+ +6Si ( OH ) 4 +KAl3Si3O10 ( OH ) 2 ( K- Feldspar ) ( Illite ) †¦ †¦ †¦ †¦ †¦ [ Eqn. 2.1 ] 2KAl3Si3O10 ( OH ) 2 + 3H2O + 2H+ i‚ «2K+ + 3Al2Si2O5 ( OH ) 4 ( Illite ) ( Kaolinite ) †¦ †¦ †¦ †¦ .

Importance of Corporate Governance and OECD Samples †MyAssignmenthelp

Question: Discuss about the Importance of Corporate Governance and OECD. Answer: Introduction The assignment focuses upon the importance of corporate governance within the context of a business organization. The organization for Economic Cooperation and Development (OECD) defines corporate governance as relationship among a companys board, management, shareholders and different stakeholders. It provides a structure for setting the objectives of the company and the means of attaining the objectives. The assignment further studies the importance of structural changes within the business context. For the current assignment, the Baby Bunting Group Company Limited (BBGCL) have been chosen which is an Australia based nursery retailer and one-stop baby shop. The company had been found and run as a family owned business organization. However, recently the majority shares of the company had been undertaken by the Government making it a public sector Company. The aim was to provide baby care products to the new born to 3 years of age at affordable prices. It further analyses the legislative requirements and the impact of the same upon controlling the internal procedures within the organization. Requirement of corporate structural changes The changes in the structures and policies of corporate governance helps in meeting with the business objectives of the organization such as protecting company assets from accidental losses, to ensure reliability of financial information, promote an environment where the staff and themanagement can maximize their productivity for the benefits of the organization (Ball et al. 2013). There are a number of reasons based upon which the corporate governance policies of a company or business organization are restructured. Some of these have been discussed within the context of the assignment such as change in management. In this respect, BBGCL have been changing its governance from that of a private retailer store to a public sector undertaking (Babybuntingcorporate 2017). Therefore, the change in ownership called for revision of the corporate governance policies of the company. In this respect, the reduction of the commodities sold by the retail group can incur sufficient amount of losses. Therefore, new policies need to be laid out where adequate resources and funds are provided by the government. The policies and pricing needs to be transparent which will prevent the overseas customer from paying more for the products sold (Too and Weaver 2014). The retail group therefore needs to clearly mention its pricing policies and terms of services and conditions over its w eb portals to prevent any forms of ethical breach. Purpose of corporate governance activities The corporate governance activities can help the board in understanding the overall organizational oversights and objectives. The attributes of the corporate governance helps in analysing the financial risks. The corporate governance framework helps in focussing upon the important issues and deal with them within limited time frame and resources (Tricker and Tricker 2015). The activities of corporate governance help to mitigate conflicts of interest and to ensure that the assets of the company are productively used in the best interest of the investors and stakeholders. The BBGCL may be facing a lot of conflicts within the international market owing to change of power. The governance activities help in upholding the organizational interests (Alexander et al. 2014). This further provides the company with an upper hand over its similar market players. Directors duties The responsibilities of the directors within the context of corporate governance could be described over here as follows. The Board of directors has the authority for resolving matters related to strategic decision making (Young and Thyil 2014). They are also responsible for monitoring the performance of the seniormanagement and employees within the retail outlet. The director plays a crucial role in planning andmanagement of the merger and acquisition activities. In the present context, the directors of the BBGCL need to daft the business objectives and present the governing objectives in front of the government. ASIC legislative requirements The Australian Securities and Investments Commission (ASIC) is an Australian government body that that acts as a corporate regulator that acts as a corporate regulator. Here, the ASIC is responsible for enforcing and regulating the financial resources of the company (Asic 2017). The goal of ASIC is to unite the corporate regulators across Australia. The following legislative requirements as established by ASIC could be followed by BBGCL such as- Promotion of informed participation by consumers and investors in the financial system Administration of law within the business establishments with procedure and hazards Make up-to-date information about the company available to the public Review of current internal control procedures The internal control procedures of the BBGCL have been discussed as follows. Some of these policies have been found to possess loopholes and gaps and needs to be reviewed or modified for the maximization of the organization productivity. Some of these are segregation of duties, implementation of authorisation procedures, maintenance of adequate records and documents, implementation of physical control for safeguarding the assets of the company, conducting independent verifications (Khan et al. 2014). However, there are issues arising with respect to implementation of the authorisation procedures and conducting of independent verification with respect to merger and acquisition. In this respect, BBGCL had been taken over by the government enterprises resulting in chaotic situations where the company cannot conduct internal verifications except in emergency situation. This becomes limitation on the part of the business organization where they cannot practise sufficient autonomy within their own operations. procedures for controlling handling of cash receipts and payments For preventing frauds and errors in the handling of cash receipts and payments a number of risk control methods could be followed. Some of the assessment tools which could be implemented over here are the Risk control Matrix. It serves as the audit plan and identifies the plausible risks that the organizations might be facing. Some of the test control results which had been applied by the BBGCL are use of electronically read barcodes indicating the specificities of the product along with the prices. It helps in accurate regirding of transaction data in much real time across large databases and prevents frauds. Conclusion The corporate governance consists of list of factors and attributes based upon which an organization is controlled and directed. The implementation of the governance policies ensures legal compliance and prevents unlawful activities or behaviour within the organization. The BBGCL follows a one-to-many relationship for establishment of a result between one control test and many control results by application of the control tests against multiple items. The multiple number of options taken into consideration which helps in focussing upon the long term strategies which could be used for mitigating the financial risks suffered by the company.
