Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1906 edition. Excerpt: ...above mentioned. The quantity of gas absorbed by each of these materials is determined by filling the tubes, as above mentioned, with the dried material. The content of each tube is previously determined by filling with mercury and weighing. Having determined the weight of the substance after the expulsion or calculation of the volume of the air contained within its pores, it is treated with the gas in the apparatus described above and weighed from time to time until no further increase of weight takes place. The method of calculating the results is shown in the following scheme: Let P' = weight of the empty tube filled with air at 100. V = content of the absorption tube. pl = weight of the air in the tube (pi = V X specific gravity of the air at 100). pt' = weight of the tube (pf = P'--pl). P3 (second weighing) = weight of the tube filled with the substance with the included air at 100. V3 = volume of the'substance calculated according to the formula F--F s!--specific gravity of the air' s' = specific gravity of the substance. vl = volume of the air in the flask filled with the substance (vl = V--v3). GENERAL METHOD OF DETERMINING ABSORPTION 319 pi' (weight of this included air) = vl X specific gravity. ps--weight of the substance (ps = pz--pt'--pl). P3 = weight of the apparatus at the end of the experiment. sg = specific gravity of the gas employed for saturation. pg (weight of the gas remaining over the substance) = vl Xsg. pa (weight of the absorbed gas)= P3--pt'--ps--pg. Then if p-gram of substance absorbs pa gram of the gas, 100 grams of substance would absorb;---grams. The specific gravities of the gases employed are calculated from the tables given by L, andolt and Bornstein in "Physical and Chemical Tables," page 5. The specific...

Book excerpt: Agriculture extension work requires more than good intentions and rapport with farmers. The real challenge is usually establishing credibility in the agriculture skills area. Agriculture at the small farmer level in a developing country is a complex endeavor. Farmers have much they can teach you when it comes to land preparation, planting, harvesting, using tools, and other manual skills. Likewise, there are many yield boosting skills you can show them, especially in the areas of soil conservation, organic and chemical fertilizer use, and the safe and appropriate use of agricultural chemicals. This manual has been designed as an on-the-job reference for soil management and fertilizer use; hopefully, it will help along that sometimes bumpy road to credibility.

This book was released on 2000-11-02 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.

Book excerpt: The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.
