  • The authors of the articles, while they mention a number of the elements in the dust, think of it as a “liming” material rather than a broad-spectrum remineralization material. Significantly, they observe: “Use of cement kiln dusts for soil liming is not a new idea, but it seems to have received little attention and the relative merits of the dust and of conventional liming materials have not been well studied.

  • During the past two centuries, scientists, farmers, and agricultural educators have tended to alternate their views of soil organic matter (SOM) between the extremes of great appreciation and low esteem. As an early 20th century bulletin explained, organic matter was “once extolled as the essential soil ingredient, the bright particular star in the firmament of the plant grower…” before it “…fell like Lucifer…” as a result of the findings of 19th century agricultural chemists that most of the plant structure (C, that is) originated in the atmosphere (Hills et al., 1908)....

  • Microbial biomass formation on root surfaces can be measured in plants growing in solution with or without an inert solid support. Carbon flow to the biomass can be measured by growing plants in solution or soil on a continuous source of 14C02 and the expected biomass formation predicted. The lack of correlation between measured and predicted biomass can be explained by oligotrophic growth of the micro-organisms.

  • Baking Soda: Sodium bicarbonate is a product that can be used as a natural fungicide for black spot, powdery mildew and brown patch by mixing 4 teaspoons (approximately 1 rounded tablespoon) per gallon of water along with one teaspoon of mild liquid soap or horticultural oil and spraying foliage. Be careful to keep the spray on the foliage and not on the soil as much as possible. Baking soda is composed of sodium and bicarbonate ñ both are necessary in the soil but only in very small amounts. Potassium bicarbonate is a good alternative for those concerned about sodium....

  • Polyethylene-starch blend polymer has already found to be a potential candidate to replace non-degradable plastic in packaging [7]. However, the degradation of that polymer in natural ambience (soil burial test) needs to be further evaluated. The purpose of this study is to investigate the degradability of PE-starch blend polymer in soil and in liquid medium. The soil is added starch degrading bacteria isolated from natural soil.

  • It is difficult to discern exposures from institutions’ reported credit market posi- tions. Indeed, common data sources such as annual reports and regulatory filings record accounting measures on a large and diverse number of credit market instruments. Ac- counting measures are not necessarily comparable across positions. For example, the economic value of two loans with the same book value but different maturities will react quite differently to changes in interest rates. At the same time, many instruments are close substitutes and thus entail essentially the same market risk.

  • This book consists of eight chapters, which are broadly divided into two themes. The first five chapters examine design features and management practices of selected agroforestry practices, and their effects on ecosystem functions and productivity. In the first Chapter, Rodríguez-Estéz et al. provide a synthesis of existing knowledge on the ecology of the dehesa, a Mediterranean agrosilvopastoral system, and how the Iberian pig production system enhances biodiversity and ecosystem services....

  • In certain countries the Company also provides postretirement benefits other than pensions to various employees. The cost relating to such plans consists of the present value of the benefits attributed on equal basis to each year of service, and interest cost on the accumulated postretirement benefit obligation, which is a discounted amount. The transition obligation is being recognized through charges to earnings over a twenty-year period beginning in 1993 in the US and in 1995 for all other plans.

  • Next, we examine predictability in both benchmark returns and fund risk loadings. Consider the dogmatist who believes in such a predictability structure (PD-2). This investor would experience a nontrivial utility loss of 15.1 basis points per month (1.8%/ year) in December 2002 if forced to hold the optimal portfolio of the ND. The utility loss is even larger over the course of all 276 monthly investments. This loss averages 21.1 (39) basis points per month over expansions (recessions).

  • While the above-described uses (and potential uses) of social media by insurance companies are important to note, it must be pointed out there is another side of the proverbial coin to social media in insurance. A not-insignificant number of insurance companies — concerned about the novelty of the medium, the lack of explicit regulatory and legal guidance, and very real practical and technical issues — have either banned the use of social media outright or taken an approach of benign disregard relative to the use of social media in connection with their...

  • In determining what a normal production level is for an insurable farmer, USDA requires the producer to present actual annual crop yields (usually stated on a bushel-per-acre basis) for the last 4 to 10 years. The simple average of a producer’s annual crop yield over this time period then serves as the producer’s actual production history (APH). If a farmer does not have adequate records, he can be assigned a transition yield (T-yield) for each missing year of data, which is based on average county yields for the crop.

  • The most fundamental aspect of Shariah compliance is the prohibition of any form of usury, or riba6 . Any amount in a contract of loan or debt – regardless of size – that exceeds the principal is riba. Such contracts are prohibited by the Quran, regardless of whether the loan is taken for the purpose of consumption or for some production activity. This indicates that any forms of receiving or paying interest are not allowed, because Islam defines all forms of interest as usury. The rationale behind the prohibition of interest in Islam suggests an economic system...

  • We also Önd evidence of a political economy story. We were motivated to pursue this story by the failure of a legislative bill in the Greek Parliament in 2010. The idea of the bill was to mandate tax audits for reported income below a minimum amount, targeted at eleven select occupations. The occupations line up almost perfectly with our results: doctors, dentists, veterinarians, lawyers, architects, engineers, topographer engineers, economists, Örm consultants and accountants.

  • As the human population inexorably grows, its cumulative impacts on the earth’s resources are hard to ignore. The ability of the earth to support more humans is dependent on the ability of humans to manage natural resources wisely. Because disturbance alters resource levels, effective management requires understanding of the ecology of disturbance. Editorship of this book was undertaken with several goals in mind. First, I wanted to present an organized summary of the many types of disturbances that impact the earth, with as global a focus as the existing literature allowed....

  • The objective of alkaline peroxide bleaching optimisation (Paper III) was to achieve a brightness of 75% ISO, with minimal sodium hydroxide consumption, whilst retaining the pulp properties. The variables studied were the pressurisation of the first peroxide (P1) stage with oxygen, the substitution of sodium hydroxide partially with sodium carbonate and a mild alkali treatment before the actual peroxide bleaching. In addition, the role of sugars in the bleaching stages was studied by adding glucose or xylose to the P1 stage. The bleaching conditions are presented in Paper III. ...

  • The engineering profession must adapt to the new low carbon paradigm well ahead of society as a whole in order to provide the necessary leadership in design and the direction of policy. The professional engineering institutions and trade associations must all recognise a multi-disciplinary, problem solving approach that over-turns conventional partisan relationships and embraces a systemic approach to construction. All contributors to construction projects must be prepared to provide leadership in their area of expertise, but work with others to link knowledge across existing boundaries.
