Results Among fifteen PFCs analyzed, perfluorohexane sulfonic acid (PFHxS), and perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorodecanoic acid (PFDA) were detected in >90% of the serum samples. The number of chemicals above median concentrations among these 5 PFCs were graded on a scale of 0 to 5, and classified into exposure (0) (...

The article that follows is a reprint of Part I of a report presented by Dalmer D. Hoskins, Secretary General of the International Social Security Association (ISSA), to the organization's XXIVth General Assembly (November 1992, Acapulco). It identifies and interprets the major trends currently influencing the evolution of social security programs around the world, and analyzes these developmen...

During these years the current trends shows a fast expansion in field of wireless sensor network (WSN) based applications. Due to this much vulnerability are created and also coverage optimization becomes essential improve overall performance. However, maximum model concentrates only on security or efficiency. In order create highly efficient protocol both concepts need get concerted. So, we de...

The aim of the present study is to synthesize the oxovanadium complex of the V3+ ion with isatin sciff bases. Spectroscopic methods have been used to confirm these models of complexation and to understand the structures of the species formed in methanolic solution. We also have isolated a complex of Vanadium (III) with isatin schiff bases in the solid phase.

Herpes simplex and vaccinia viruses and adenovirus types 1, 2, 5, and 7 were tested by plaque suppression methods for sensitivity to halogenated deoxyuridines (5-iodo-, 5-bromo-, 5-chloro-, and 5-fluoro-), cytosine arabinoside, isatin-beta-thiosemicarbazone, and N-methylisatin-beta-thiosemicarbazone. After incubation for 12 days in HeLa cell cultures, vaccinia virus plaques were still readily s...

A series of backbone modified and sulfonic acid replacement analogs of our topical, clinical candidate (iii) were synthesized. Their antimicrobial activities and aqueous stabilities at pH 4 and pH 7 were determined, and has led us to identify quaternary ammonium N,N-dichloroamines as a new class of topical antimicrobial agents.

The reactions of bis(cyclopentadienyl)titanium(IV) dichloride with a new class of thiosemicarbazone (LH(2)), derived by condensing isatin with different N(4)-substituted thiosemicarbazides, have been studied and products of type [Cp(2)Ti(L)] have been isolated. On the basis of various physico-chemical and spectral studies, five coordinate structures have been assigned to these derivatives. Toxi...

The title compound, C(9)H(14)N(+)·C(7)H(7)SO(3) (-), contains a 2-ethyl-6-methyl-anilinium cation and a 4-methyl-benzene-sulfonic anion. The cations are anchored between the anions through N-H⋯O hydrogen bonds. Electrostatic and van der Waals inter-actions, as well as hydrogen bonds, maintain the structural cohesion.

The internal temperature of the pigsty has a great impact on pigs. Keeping in within certain range is pressing problem environmental control. current regulation method based mainly manual and simple automatic There rarely intelligent control, such direct methods have problems as low control accuracy, high energy consumption untimeliness, which can easily lead to occurrence heat stress condition...
