  • Consumer concerns on food safety and society awareness of chemical contaminants in the environment have increased in the past few years. As a consequence, more restrictions in the use of chemical products have been imposed at national and international levels. Pesticides are widely used for the control of weeds, diseases, and pests of cultivated plants all over the world, mainly since after Second World War, with the discovery of some organic compounds with good insecticide or herbicide activity. At present, around 2.

  • An experiment was carried out in the greenhouse conditions with Brassica juncea L. grown on alluvial soils that had previously been contaminated at different concentrations of Cu. The main purposes of the research were to determine the effects of Cu and phosphorus applications on plant growth and Cu uptake by Brassica juncea L. Mature plants were harvested for the Cu accumulation analysis. The soil samples from each growing pot were extracted by HNO3 0.

  • The past decade has seen the field of proteomics expand from a highly technical endeavor to a widely utilized technique. The objective of this book is to highlight the ways in which proteomics is currently being employed to address issues in the biological sciences. Although there have been significant advances in techniques involving the utilization of proteomics in biology, fundamental approaches involving basic sample visualization and protein identification still represent the principle techniques used by the vast majority of researchers to solve problems in biology.

  • In the case of Writing and Speaking, however, the small increases in the mean scores did not reflect a significant improvement. For Writing, the sample mean of 6.33 (SD = .64) was not significantly different from 6.21, t(39) = -0.95, p .05. Likewise, for Speaking, the sample mean of 6.66 (SD = .78) was not significantly different from 6.50, t(39) = -1.25, p .05. The results of the paired sample t-test conducted on the Overall score did, however, indicate an improvement.

  • Restating and control firms appear very similar in the measurable degree of influence that the CEO exerts on the board. Panel D of Table 5 shows that the CEO chairs the board in about 64 percent (62 percent) of the restating (control) firms. The CEO’s median tenure on the board is 5 (7) years in restating (control) firms. The CEO belongs to the founding family in 26 percent (20 percent) of the firms in the two samples. The CEO appears to pick board members in 80 percent (82 percent) of the firms in the two groups. None of these differences are statistically significant....

  • From microorganisms to whales, from single cells to complex organisms, from plants to animals to fungi, from body plans to behavior, the diversity of life is amazing. Living organisms have a profound impact on our physical world of ocean, landscape, and climate; around us is a multitude of diverse ecosystems that provide a livable environment and many valuable resources. The study of life—biology—is a multifaceted endeavor that uses observation, exploration, and experiments to gather information and test hypotheses about topics ranging from climate change to stem cells.

  • Out of the initial sample of 303 restating firms identified from news reports, 216 firms are listed on Standard & Poor’s Compustat database. Out of those, we were able to find a control firm for 185 firms.24 For each of these 185 restating firms, we tried to obtain detailed information on the nature and characteristics of the restatement by reading the relevant SEC filings (Forms 10K, 10K-A, 10Q, and 10Q-A). For 10 firms, despite the initial news reports, we could not find any indication of a restatement in these filings.

  • Prenatal diagnosis, traditionally used as a synonymous for invasive fetal testing and evaluation of chromosomal constellation, presently encompasses many other issues like pedigree analyses, fetal risk assessment, population screening, genetic counseling and fetal diagnostic testing as well. Ultrasound guided chorionic villus samling (CVS), amniocentesis and, to a lesser extent, fetal blood sampling are used routinely in fetal medicine units. Other fetal tissue biopsies such as skin, liver and muscle biopsy are used only rarely.

  • All coefficients are statistically significant at the one percent level, except for collateral, which is significant at the 10 percent level. All coefficients have the same sign as in the standard regressions of Rajan and Zingales (1995), Frank and Goyal (2004) and as in our leverage regression using a sample of the largest firms (except the market to book ratio, which is insignificant for the market leverage of those firm). Banks’ leverage depends positively on size and collateral, and negatively on the market-to-book ratio, profits and dividends.

  • The regression results do not support the hypothesis that emissions from the two maquiladoras disproportionately affect the poor. The coefficients for CONCENTRATION is only significantly different from zero in one of the four models—that for uncontrolled emissions from the iron foundry. However, the sign is negative. This implies that higher PM10 concentrations are typically found in wealthier AGEBs, not in poorer ones. Thus, overall, we find no evidence that emissions from the two maquiladoras in our sample disproportionately affect the poor.

  • We have used a limited data set—comprised of a sector-level emissions inventory and original emissions estimates for a small sample of industrial facilities—to shed light on the links between maquiladoras, air pollution, and human health in Paso del Norte. We found that particulate emissions from maquiladoras undoubtedly have significant impacts on human health—collectively, these plants are probably responsible for dozens of cases of premature mortality and thousands of cases of respiratory disease each year.
