Description: In order to study characteristics of pressure fluctuation of a turbine during the starting period, a turbine with guide vanes device at no-load condition was investigated using RNG k- ##IMG## [http://ej.iop.org/icons/Entities/epsilon.gif] {epsilon} turbulence model. The inner flow distribution and pressure fluctuation characteristics were analyzed. Results show that the pressure fluctuations in the region between the runner and guide vanes are different around the runner inlet. The dominant frequency of pressure fluctuation in the vaneless space close to the casing outlet is the blade passing frequency, while the dominant frequency at the rest region is the twice of the blade passing frequency. The increase of amplitude of pressure fluctuation close to the casing outlet can be attribute to the large scale stall at suction side of the runner inlet.

Description: This paper presents a novel fault detection method for photovoltaic (PV) array using an improved two-stage Hampel identifier, which can quickly detect the occurrence of faults and locate them at PV module level. The fault detection method is implemented in a two-level wireless sensor network based distributed on-line monitoring system which is developed to monitor the voltage of each PV module and current of all parallel PV strings in real-time. The 1 st stage Hampel identifier detects and locates the faulty PV strings by comparing the instantaneous currents of different PV strings. The 2 nd stage Hampel identifier detects and locates the faulty PV modules by comparing the instantaneous voltages of different PV modules in the faulty strings. Experimental results show that the proposed method can successfully detect and locate faulty strings and modules in several faulty cases, including the line-line faults, the degradation faults, the partial shading faults ...

Description: A novel hydroxyl-terminated liquid fluoroelastomer (HTLF) was synthesized; FT-IR, GPC and 1 H-NMR result show that HTLF was synthesized successfully. Then HTLF was cured with HDI trimer, the structure of cured product was characterized by FT-IR. Compared with traditional solid fluorine elastomer, Cured HTLF has higher char yield and faster thermal decomposition rate. It ascribed to the introduction of ring structure the cross-link structure formed in the curing process. The study of chemical resistant properties and tensile strength of cured fluoroelastomer film suggested that Cured HTLF was provided with similar mmechanical properties, chemical resistant property than solid fluorine elastomer.

Description: This paper focuses on the experimental study of the influence of surface curvature to the behaviour of HIFU-induced cavitation cloud. A Q-switched ruby pulse laser is used to induce cavitation nuclei in deionized water. A piezoelectric ultrasonic transducer (1.7 MHz) provides a focused ultrasound field to inspire the nucleus to cavitation cloud. A PZT probe type hydrophone is applied for measuring the HIFU sound field. It was observed that the motion of cavitation cloud located near the boundary is significantly influenced by the distance between cloud and boundary, as well as the curvature of the boundary. The curvature was defined by parameters λ and ξ . Convex boundary, concave boundary, and flat boundary correspond to ξ 1 and ξ = 1, respectively. Different behaviours of the cloud, including the migration of the cloud, the characteristics of oscillation, etc., were observed under different boundary curvatures by high-speed photog...

Description: Land condition assessment is a basic prerequisite for finding the degradation of a territory, which might lead to desertification under climatic and human pressures. The temporal change in vegetation productivity is a key indicator of land degradation. In this paper, taking the Otindag Sandy Land as a case, the mean normalized difference vegetation index (NDVI_a), net primary production (NPP) and vegetation rain use efficiency (RUE) dynamic trends during 2001–2010 were analysed. The Mann-Kendall test and the Correlation Analysis method were used and their sensitivities to land degradation were evaluated. The results showed that the three vegetation indicators (NDVI_a, NPP and RUE) showed a downward trend with the two methods in the past 10 years and the land was degraded. For the analysis of the three vegetation indicators (NDVI_a, NPP and RUE), it indicated a decreasing trend in 62.57%, 74.16% and 88.56% of the study area according to the Mann-Kendall test and in 57.85%, 68.38%...

Description: The autism spectrum disorders (ASDs) are a group of conditions characterized by impairments in reciprocal social interaction and communication, and the presence of restricted and repetitive behaviours. Individuals with an ASD vary greatly in cognitive development, which can range from above average to intellectual disability. Although ASDs are known to be highly heritable ( approximately 90%), the underlying genetic determinants are still largely unknown. Here we analysed the genome-wide characteristics of rare (〈1% frequency) copy number variation in ASD using dense genotyping arrays. When comparing 996 ASD individuals of European ancestry to 1,287 matched controls, cases were found to carry a higher global burden of rare, genic copy number variants (CNVs) (1.19 fold, P = 0.012), especially so for loci previously implicated in either ASD and/or intellectual disability (1.69 fold, P = 3.4 x 10(-4)). Among the CNVs there were numerous de novo and inherited events, sometimes in combination in a given family, implicating many novel ASD genes such as SHANK2, SYNGAP1, DLGAP2 and the X-linked DDX53-PTCHD1 locus. We also discovered an enrichment of CNVs disrupting functional gene sets involved in cellular proliferation, projection and motility, and GTPase/Ras signalling. Our results reveal many new genetic and functional targets in ASD that may lead to final connected pathways.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3021798/"

Description: In recent years, with the continuous development of urbanization in China, construction equipment and technology in the field of building are developing rapidly. China has made much progress in this field, but there is also a gap in comparison. Rapid growth needs to follow the appropriate direction of development. In the future, China will further accelerate the speed of urban intensive construction, so it is of great significance to find a correct direction for the development of Chinese cities. Based on this purpose, this paper summarizes the current situation and rules of building equipment and technology in the view of the rapid development of modern architecture and related practical achievements. This article further analyses the building technology and equipment from the aspects of social culture, political economy, laws and regulations, and discipline development. The conclusion is that in the future development of buildings, the energy saving of construction equipment a...

Description: High-resolution speleothem records from China have provided insights into the factors that control the strength of the East Asian monsoon. Our understanding of these factors remains incomplete, however, owing to gaps in the record of monsoon history over the past two interglacial-glacial cycles. In particular, missing sections have hampered our ability to test ideas about orbital-scale controls on the monsoon, the causes of millennial-scale events and relationships between changes in the monsoon and climate in other regions. Here we present an absolute-dated oxygen isotope record from Sanbao cave, central China, that completes a Chinese-cave-based record of the strength of the East Asian monsoon that covers the past 224,000 years. The record is dominated by 23,000-year-long cycles that are synchronous within dating errors with summer insolation at 65 degrees N (ref. 10), supporting the idea that tropical/subtropical monsoons respond dominantly and directly to changes in Northern Hemisphere summer insolation on orbital timescales. The cycles are punctuated by millennial-scale strong-summer-monsoon events (Chinese interstadials), and the new record allows us to identify the complete series of these events over the past two interglacial-glacial cycles. Their duration decreases and their frequency increases during glacial build-up in both the last and penultimate glacial periods, indicating that ice sheet size affects their character and pacing. The ages of the events are exceptionally well constrained and may thus serve as benchmarks for correlating and calibrating climate records.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Yongjin -- Cheng, Hai -- Edwards, R Lawrence -- Kong, Xinggong -- Shao, Xiaohua -- Chen, Shitao -- Wu, Jiangyin -- Jiang, Xiouyang -- Wang, Xianfeng -- An, Zhisheng -- England -- Nature. 2008 Feb 28;451(7182):1090-3. doi: 10.1038/nature06692.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉College of Geography Science, Nanjing Normal University, Nanjing, Jiangsu 210097, China. yjwang@njnu.edu.cn〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18305541" target="_blank"〉PubMed〈/a〉

Description: Galactic cosmic rays consist of protons, electrons and ions, most of which are believed to be accelerated to relativistic speeds in supernova remnants. All components of the cosmic rays show an intensity that decreases as a power law with increasing energy (for example as E(-2.7)). Electrons in particular lose energy rapidly through synchrotron and inverse Compton processes, resulting in a relatively short lifetime (about 10(5) years) and a rapidly falling intensity, which raises the possibility of seeing the contribution from individual nearby sources (less than one kiloparsec away). Here we report an excess of galactic cosmic-ray electrons at energies of approximately 300-800 GeV, which indicates a nearby source of energetic electrons. Such a source could be an unseen astrophysical object (such as a pulsar or micro-quasar) that accelerates electrons to those energies, or the electrons could arise from the annihilation of dark matter particles (such as a Kaluza-Klein particle with a mass of about 620 GeV).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chang, J -- Adams, J H -- Ahn, H S -- Bashindzhagyan, G L -- Christl, M -- Ganel, O -- Guzik, T G -- Isbert, J -- Kim, K C -- Kuznetsov, E N -- Panasyuk, M I -- Panov, A D -- Schmidt, W K H -- Seo, E S -- Sokolskaya, N V -- Watts, J W -- Wefel, J P -- Wu, J -- Zatsepin, V I -- England -- Nature. 2008 Nov 20;456(7220):362-5. doi: 10.1038/nature07477.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Purple Mountain Observatory, CAS, 2 West Beijing Road, Nanjing 210008, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19020615" target="_blank"〉PubMed〈/a〉
