A previous analysis of the Chandra X-ray image of the center of the cooling core cluster Abell 2597 showed two “ghost holes” in the X-ray emission to the west and northeast of the central radio galaxy PKS 2322−123. Previous radio observations did not detect any radio emission coming from the interior of the X-ray holes. We present new low frequency radio observations of Abell 2597. At 330 MHz, ...

Drosophila suzukii Matsumura, 1931 (Diptera: Drosophilidae) is an invasive pest species that causes damage to fruit crops due premature deterioration of ripe fruits by oviposition inside them. A review D. detections in Argentina was carried out and we updated this list with the results our sampling Northwest, Cuyo Northeast regions. The surveys determined first provinces Jujuy Córdoba, revealin...

Research on precipitation regularity in the past 120 years is an important link analyzing characteristics of watersheds. This paper systematically analyzes characteristic changes centennial data Haihe River basin with help CRU data, PCI, SPI, and Pearson type III curve. The results show that spatial temporal distribution has a more obvious inconsistency. shows relatively stable early period inc...

Several ranges encompassing more than 35,000 km 2 of Sonora, Mexico, contain distinctly lineated and foliated granitic and metamorphic rocks that constitute the lower plates of metamorphic core complexes. Penetrative deformation is characterized by gently dipping mylonitic foliation across which northeast trending stretching lineation is everywhere developed. Prominent northwest trending fractu...

Wind erosion is one of the major meteorological hazards in Ningxia, and climate change has caused changes wind erosion–climatic activity recent years. This study uses factor (C) proposed by Food Agriculture Organization United Nations to assess impact on erosion–climate erosion, results show that (1) distribution degree Ningxia region central > northern southern. Seasonally, it higher spring...

background: the plerocercoid stage of pseudophyllideancestoda infected a wide range of fresh water fish,particularly the members of the cyprinidae family. the parasitespecies are the most common pathogens that have severe effectson fish. objectives: the aim of the present study is todetermine the occurrence and distribution of the plerocercoid ofdiphyllobothriidae in two freshwater fish from no...

Based on a great number of literatures, we established the database about the Chinese endemic seed plants and analyzed the compositions, growth form, distribution and angiosperm original families of them within three big natural areas and seven natural regions. The results indicate that the above characters of Chinese endemic plants take on relative rule at the different geographical scales. Am...
