Effect of Safety Climate on Employees' Organizational Commit-ment Mediated by Ethics in Gas Refining Companies
The goal of protecting the aquatic environment through testing thousands of chemicals against hundreds of aquatic species with thousands of endpoints while also considering mixtures is impossible given the present resources. Much of the impetus for studies on micropollutants, such as pharmaceuticals, came from the topic of endocrine disruption in wild fish. But despite concern over reductions i...
Phytoremediation of creosote-contaminated soil was monitored in the presence of Tall fescue, Kentucky blue grass, or Wild rye. For all three grass species, plant growth promoting rhizobacteria (PGPR) were evaluated for plant growth promotion and protection of plants from contaminant toxicity. A number of parameters were monitored including plant tissue water content, root growth, plant chloroph...
The first spectral measurement of Earth’s emitted radiation to space in the wideband range from 100 to 1400 cm−1 with 0.5 cm−1 spectral resolution is presented. The measurement was performed from a stratospheric balloon in tropical region using a Fourier transform spectrometer, during a field campaign held in Brazil in June 2005. The instru5 ment, which has uncooled components including the det...
Stoner, K.A., Sawyer, A.J. and Shelton, A.M., 1986. Constraints to the implementation of IPM programs in the U.S.A.: A course outline. Agric. Ecosystems Environ., 17: 253--268. To develop and implement the pest management programs of the future, students in crop protection should be educated about the economic, social and institutional contexts in which these programs will operate.

DNA methyltransferase 3B (Dnmt3b) belongs to a family of enzymes responsible for methylation of cytosine residues in mammals. DNA methylation contributes to the epigenetic control of gene transcription and is deregulated in virtually all human tumors. To better understand the generation of cancer-specific methylation patterns, we genetically inactivated Dnmt3b in a mouse model of MYC-induced ly...
