Many nitrogen-containing aromatic compounds （NACs）, such as nitrobenzene （NB）, 4-nitrophenol （4-NP）, aniline （AN）, and 2,4-dinitrophenol （2,4-DNP）, are environmentally hazardous, and their removal from contaminated water is one of the main challenges facing wastewater treatment plants. In this study, synthetic wastewater containing NB, 4-NP, 2,4-DNP, and AN at concentrations ranging from 50 to 180 mg/l was fed into a sequencing batch reactor （SBr）. Analyses of the SBr system indicated that it simultaneously removed more than 99% of the NACs at loading rates of 0.36 kg NB/（m^3·d）, 0.3 kg 4-NP/（m^3·d）, 0.25 kg AN/（m^3·d）, and 0.1 kg 2,4-DNP/（m^3·d）. Bacterial groups of Bacteriodetes, Candidate division TM7, α-Proteobacteria, and β-Proteobacteria were dominant in the clone libraries of 16S rrNA genes retrieved from the microbial communities in the SBr system. ＂Cycle tests＂ designed to alter feeding and aeration parameters of the SBr system demonstrated that the resident microbial biome of the SBr system responded rapidly to changing conditions. Consumption of O2 was concomitant with the apparent mineralization of NACs. Aromatic ring-cleaving dioxygenase activities suggested that （1） AN and NB were degraded via catechol 2,3-dioxygenase; （2） 4-NP was degraded via 1,2,4-benzentriol 1,2-dioxygenase; and （3） 2,4-DNP was degraded via an unresolved pathway.

Metastatic breast cancer involving the hepatobiliary tract or ascites secondary to peritoneal carcinomatosis has been well described. luminal gastrointestinal tract involvement is less common and recognition of the range of possible presentations is important for early and accurate diagnosis and treatment. We report 6 patients with a variety of presentations of metastatic breast cancer of the luminal gastrointestinal tract. These include oropharyngeal and esophageal involvement presenting as dysphagia with one case of pseudoachalasia, a linitis plastica-like picture with gastric narrowing and thickened folds, small bowel obstruction and multiple strictures mimicking Crohn’s disease, and a colonic neoplasm presenting with obstruction. lobular carcinoma, representing only 10% of breast cancers is more likely to metastasize to the gastrointestinal tract. These patients presented with gastrointestinal manifestations after an average of 9.5 years and as long as 20 years from initial diagnosis of breast cancer. Given the increased survival of breast cancer patients with current therapeutic regimes, more unusual presentations of metastatic disease, including involvement of the gastrointestinal tract can be anticipated.

This research seeks to provide a descriptive study of the English translation of the breakthrough Chinese novel red Sorghum by Mo Yan. The novel is a prime example for the research into strategies and norms in translation within a Chinese-English framework for three main reasons. Firstly, due to the huge impact the novel has had in terms of its truth-telling about the Sino-Japanese War(1937 – 1945) in China. Secondly, because of Mo Yan's unique non-linear writing style, and thirdly for the fact that the novel was translated by Howard Goldblatt, who is an American native English speaker, which is fairly rare in terms of ChineseEnglish translations. This research seeks not only to provide a descriptive study of Howard Goldblatt's English translation of the breakthrough Chinese novel but also to explore the strategies he employs during the translation process. An investigation is carried out to determine whether Goldblatt makes use of particular translation strategies and follows these approaches throughout the novel, thereby creating certain translational norms. Through primary research into the novel one would find that this is in fact the case. For example, he makes use of a domesticating approach in terms of translating Chinese cultural items, phrases, or terms. However, it is only through more in-depth research and a close comparison of the source and target texts, that one finds that Goldblatt does not in fact follow similar strategies in every instance but uses them sporadically throughout the novel according to the context or message that must be carried across. These discoveries are significant in that they are not entirely what is expected nor what is initially found by other ***, the results of this research along with the descriptive study of the translation of red Sorghum and the investigations into the translation strategies and norms at play during the translation process allow for better understanding of the translation process.

Two genera of fangless homalopsid snakes Brachyorrhos and Calamophis from eastern Indonesia have been described as basal members of the clade. A third genus belonging to this group from Sumatra, Indonesia is described here based upon morphology. Fangless homalopsid snakes share 19 dorsal scale rows at mid-body, fused dorsal scales above the cloaca, 5 to 7 upper labials, divided anal plate, divided subcaudals, 15-21 teeth on the dentary, frontal bone about 23% of skull length and other morphological characters that suggest they are related. All the three genera are known only from Indonesia. The new genus and species have a distinctive skull morphology with an absent premaxilla, a more depressed skull, and a larger eye than are present in Brachyorrhos.
