In 2008,the IUCN threat status of the Asian tapir(Tapirus indicus)was reclasified from‘vulnerable'to‘en-dangered'.The latest distribution map from the IUCN Red List suggests that the tapirs'native range is becom-ing increasingly fragmented in Peninsular Malaysia,but distribution data collected by local researchers sug-gest a more extensive geographical ***,we compile a database of 1261 tapir occurrence records within Peninsular Malaysia,and demonstrate that this species,indeed,has a much broader geographical range than the IUCN range map ***,extreme spatial and temporal bias in these records limits their utility for conservation ***,we used maximum entropy(MaxEnt)modeling to elucidate the potential ex-tent of the Asian tapir's occurrence in Peninsular Malaysia while accounting for bias in existing distribution *** MaxEnt model predicted that the Asian tapir has a wider geographic range than our fine-scale data and the IUCN range map both *** 37%of Peninsular Malaysia contains potentially suit-able tapir *** results justify a revision to the Asian tapir's extent of occurrence in the IUCN Red ***,our modeling demonstrated that selectively logged forests encompass 45%of potentially suitable tapir habitats,underscoring the importance of these habitats for the conservation of this species in Peninsular Malaysia.

World Journal of Gastroenterology 2009年第39期15卷 4928-4931页

作者： Murdani abdullah Hiroyuki Ohtsuka abdul aziz Rani Tadashi Sato Ari F Syam Masayuki A Fujino Division of Gastroenterology Department of Internal MedicineFaculty of Medicine University of IndonesiaCipto Mangunkusumo Hospital First Department of Medicine Yamanashi Medical University

AIM： To compare the effects of He/icobacter py/ori （Hpylon） infection on gastropathy between Indonesian and Japanese patients. METHODS： Biopsy specimens were obtained during upper gastrointestinal endoscopy from 167 subjects （125 Indonesians and 42 Japanese） with uninvestigated symptoms of dyspepsia. The specimens were analyzed for the presence of H pylori using urease analysis, histopathology, and cell culture. The grade and activity of gastritis was assessed using the updated Sydney system. RESULTS： The percentages of Indonesian and Japanese patients who were H py/ori-positive at the antrum or body of the stomach were similar （68% and 59.5%, respectively; P = 0.316）. Of those who were Hpylori-positive, more Japanese patients than Indonesian patients had high levels of polymorphonuclear cells （P = 0.001）, mononuclear cells （P = 0.013）, glandular atrophy （P = 0.000）, and intestinal metaplasia （P = 0.011） in both the antrum and body of the stomach. CONCLUSION： The grade of gastritis and prevalence of mucosal atrophy and intestinal metaplasia were higher in Japanese patients. The difference between Indonesian and Japanese patients was significant.

以VOPO4.2H2O为原料制备了钒磷氧化物催化剂,考察了镍掺杂(1%,2%和5%)对该催化剂的影响.低掺杂量的Ni明显提高了活性晶格氧物种O-的数量,降低了V5+和V4+相的还原峰温.粉末X射线衍射、程序升温还原和化学分析结果表明,高掺杂量的Ni促使V5+物相生成并抑制V4+物相出现.高含量与V5+相关的氧物种会降低正丁烷的转化率,但会提高马来酸酐的选择性.

Impact of renewable power market penetration on coal power generation capacity growth

引用

Journal of Coal Science & Engineering(China) 2011年第2期17卷 217-224页

作者： abdul Majeed aziz R. Larry Grayson VLADISLAV Kecojevic The Pennsylvania State University（University Park） 16802 USA West Virginia University Morgantown WV26506-6070 USA

Since renewable energy sources are growing in importance, how well they can penetrate the energy market for power generation will be a very important factor in the role the coal industry will play in the future. This paper examined the displacement of coal power plant capacity from 2010 to 2050 by renewables with respect to three drivers assumed under various conditions： the American Recovery and Reinvestment Act （ARRA）, Greenhouse Gas （GItG） policy, and varying plant capital cost cases. The results by 2050 illustrate that renewable market penetration captures anywhere from 1.9% to 6.4% of potential coal power generation capacity additions. Renewable power generation capacity additions is expected to outpace coal power plant additions by 89% with respect to ARRA in 2050, however with no GHG policy coal power generation capacity build-outs will outpace renewables by as high as 809%. Finally, coal power generation is still projected to be the largest single energy source contributor to the electricity market making up 28.0% of total available capacity, while renewables are expected to only make up 16.3% of total available capacity.

Optimization of moderator assembly for neutron flux measurement:experimental and theoretical approaches

引用

Nuclear Science and Techniques 2017年第5期28卷 7-12页

作者： abdul Waheed Nawab Ali Muzahir A.Baloch aziz A.Qureshi Eid A.Munem Muhammad Usman Rajput Tauseef Jamal Wazir Muhammad Radiation Physics Laboratory Physics DepartmentCOMSATS Institute of Information Technology(CIIT)

A moderator of paraffin wax assembly has been demonstrated where its thickness can be optimized to thermalize fast neutrons. The assembly is used for measuring fast neutron flux of a neutron probe at different neutron energies, using BF03(U10and 200) and3He(U0.500)neutron detectors. The paraffin wax thickness was optimized at 6 cm for the neutron probe which contains an Am–Be neutron source. The experimental data are compared with Monte Carlo simulation results using MCNP5 version 1.4. Neutron flux comparison and neutron activation techniques are used for measuring neutron flux of the neutron probe to validate the optimum paraffin moderator thickness in the assembly. The neutron fluxes are measured at(1.17 ± 0.09) 9 105 and(1.19 ± 0.1) 9 105n/s, being in agreement with the simulated values. The moderator assembly can easily be utilized for essential requirements of neutron flux measurements.

OBJECTIVE: To investigate the inhibitive efficacy of Nymphoides Indica(L.) Kuntze rhizome extract onα-glucosidase and on cross-link formation of advanced glycation end products(AGEs).METHODS: The plant extracts were prepared by cold maceration and fractionated in solvents of diverse polarity. The in vitro α-glucosidase inhibition assay, fluorescence spectrometry and SDS-PAGE analysis was performed for antiglycation ***: During α-glucosidase inhibition assay significant inhibition by chloroform(0.43 mg/mL)and methanol fractions(0.66 mg/mL) was *** the AGEs inhibition assay, both oxidative(BSA-MGO) and non-oxidative(BSA-glucose)modes were employed. The inhibition of AGEs by total extract was considered moderate(IC_(50)0.10 mg/mL) as a result of non-oxidative mode, whereas in case of oxidative mode(BASA-MGO) no activity was recorded. Among fractions the methanolic fraction presented significant results both in oxidative(IC_(50)0.01 mg/mL) and non-oxidative modes(IC_(50) 0.3 mg/mL). Likewise the ethyl acetate fraction was more active in non-oxidative mode(IC_(50)0.04 mg/mL) compared to oxidative mode(IC_(50)0.32 mg/mL).During assay for inhibition of cross-link formation,the chloroform fraction significantly inhibited cross-link formation in a dose dependent ***: It was finally concluded that N. Indica rhizome extract possesses significant properties that inhibit α-glucosidase, and AGEs cross-link formation.
