Fresh water sources in Egypt are less than 13% of the world average per capita. To meet growing wtaer and electricity demands, projections were made up to the year 2025 cnsidering population growth, rise in standard of living, and development plans. A medium-sized nuclear desalination reactor was found to be a viable choice. This study was made to determine a suitable site for a plant in the water-sarce coastal governates of Matrouh, Red Sea, North Sinai, and South Sinai. Considering the effect of extreme climatic and geomorphological conditions on the plant and the effect of the plant on the area, it was found that the coastal strips from El-Arish to Rafah and from El-Dabaa to Saloum are the most suitable areas for construction of a nuclear power plant.

We use mutual information and symbolization method of time series to construct minimum spanning tree of the financial network of log-returns and trading volumes of the top 110 companies on the Chinese stock market listed on the CSI 300 index from January 2014 to December 2017 to analyze the Chinese stock market's turbulence during 2015 to 2016. We construct three minimum spanning trees of pre-turbulence, turbulence and post-turbulence. The findings show that minimum spanning tree of turbulence has the significant differences in topological characteristics and network's measures with pre-turbulence and post-turbulence networks. Furthermore, the pre-turbulence network is robust against nodes attack while turbulence network is fragile against it. (C) 2019 Elsevier B.V. All rights reserved.

The Mythimna unipuncta nucleopolyhedrovirus isolate KY310 (MyunNPV-KY310) is an alphabaculovirus isolated from a true armyworm (Mythimna unipuncta) population in Kentucky, USA. Occlusion bodies of this virus were examined by electron microscopy and the genome sequence was determined by 454 pyrosequencing. MyunNPV-KY310 occlusion bodies consisted of irregular polyhedra measuring 0.8-1.8 mu m in diameter and containing multiple virions, with one to six nucleocapsids per virion. The genome sequence was determined to be 156,647bp with a nucleotide distribution of 43.9% G+C. 152 ORFs and six homologous repeat (hr) regions were annotated for the sequence, including the 38 core genes of family Baculoviridae and an additional group of 26 conserved alphabaculovirus genes. BLAST queries and phylogenetic inference confirmed that MyunNPV-KY310 is most closely related to the alphabaculovirus Leucania separata nucleopolyhedrovirus isolate AH1, which infects Mythimna separata. In contrast, MyunNPV-KY310 did not exhibit a close relationship with Mythimna unipuncta nucleopolyhedrovirus isolate #7, an alphabaculovirus from the same host species. MyunNPV-KY310 lacks the gp64 envelope glycoprotein, which is a characteristic of group II alphabaculoviruses. However, this virus and five other alphabaculoviruses lacking gp64 are placed outside the group I and group II clades in core gene phylogenies, further demonstrating that viruses of genus Alphabaculovirus do not occur in two monophyletic clades. Potential instances of MyunNPV-KY310 ORFs arising by horizontal transfer were detected. Although there are now genome sequences of four different baculoviruses from M. unipuncta, comparison of their genome sequences provides little insight into the genetic basis for their host specificity.

Dedicated breast computed tomography (CD is the latest in a long history of breast imaging techniques dating back to the 1960s. Breast imaging is performed both for cancer screening as well as for diagnostic evaluation of symptomatic patients. Dedicated breast CT received US Food and Drug Administration approval for diagnostic use in 2015 and is slowly gaining recognition for its value in diagnostic 3-dimensional imaging of the breast, and also for injected contrast-enhanced imaging applications. Conventional mammography has known limitations in sensitivity and specificity, especially in dense breasts. Breast tomosynthesis was US Food and Drug Administration approved in 2011 and is now widely used. Dedicated breast CT is the next technological advance, combining real 3-dimensional imaging with the ease of contrast administration. The lack of painful compression and manipulation of the breasts also makes dedicated breast CT much more acceptable for the patients. (C) 2018 Elsevier Inc. All rights reserved.
China’s thermal coal imports in November fell to their lowest level since July 2017, suggesting that the government’s stricter enforcement of import curbs is having an effect. Thermal coal imports — which include imported shipments of lignite, bituminous, and sub-bituminous coal — totalled 13.52mn t in November, down by 15pc from 15.97mn t in November 2017, according to China’s customs administration data. The imports also fell by 18pc compared with the previous month of October when thermal coal imports totalled 16.45mn t.
