We present here three expression plasmids for Trypanosoma cruzi adapted to the Gateway® recombination cloning system. Two of these plasmids were designed to express trypanosomal proteins fused to a double tag for tandem affinity purification (TAPtag). The TAPtag and Gateway® cassette were introduced into an episomal (pTEX) and an integrative (pTREX) plasmid. Both plasmids were assayed by introd...

In 1994 and 1995, nesting success of double-crested cormorants (Phalacrocorax auritus) was measured at Cat Island, in southern Green Bay, Lake Michigan, Wisconsin, USA. Sample eggs at pipping and unhatched eggs were collected and analyzed for organochlorines (including total polychlorinated biphenyls [PCBs] and DDE), hepatic microsomal ethoxyresorufin-O-dealkylase (EROD) activity in embryos, an...

S U M M A R Y We carry out high-frequency analyses of Claerbout’s double-square-root equation and its (numerical) solution procedures in heterogeneous media. We show that the double-square-root equation generates the adjoint of the single-scattering modelling operator upon substituting the leading term of the generalized Bremmer series for the background Green function. This adjoint operator yi...

Background & Aim: In this study, is done during one-year research on blue–green and green algae for antimicrobial activity in Mashhad suburb. Aqueous, ether, and methanol extracts from 44 species blue – green algae and green algae were examined for antimicrobial properties against four bacteria (tow positive gram bacteria and tow negative gram bacteria) and tow fungous. Material & Methods: Amo...

organizations in order to capture sustainability and competitive advantage need to pay attention to environmental issues throuoghout their supply chain. by decreasing costs, improving image and being protected against environmental laws it can lead to organizational competitive advantage. current research has been done investigating the relationship between green supply chain and capturing cope...

objective: dental caries is a common infectious disease. streptococcus mutans is the prevalent decay microorganism. the anti streptococcus mutans activity of non fermented and semi-fermented tea has been shown. the aim of this study was to determine the anti streptococcus mutans activity of iranian green and black tea (non fermented and fermented type). materials and methods: the study was expe...

Quantitative identification of physical changes, developments and dynamic position of urban green space is considered as the first step in its planning. By means of the aerial photos taken in 1956, 1974, and 1994 as well as the Quick Bird satellite image captured in 2006, this study has dealt with changes in per capita green space in Khorramabad during these years. First, geometric corrections ...
