Lake Victoria the second largest fresh water body in the world located in East Africa is a shared resource between Kenya, Tanzania and Uganda and enjoys a wide range of stream. and rivers from.as far as Burundi and Rwanda. The lake has environm.ntally undergone physical, chem.cal and biological changes in the last four decades, particularly rise in its trophic condition and decline in oxygen level, which affects the water quality and fish population dynam.cs. This study therefore set out to determ.ne the quality of water in selected fishing beaches of Lake Victoria, Kenya with a view to report the possible pollution levels. pH was highest at Nyam.sari and Kotieno (9.3 ± 0.1) and lowest at Nyachebe and Kichinjio (7.08 ± 0.1) whereas tem.erature was highest at Nyam.sari (29.5°C ± 0.0°C) and lowest at Kichinjio (23.4°C ± 0.2°C). DO was highest at Kotieno (10.3 ± 0.2 m.L) and lowest at Seka (2.4 ± 0.1 m.L). Turbidity was highest at Uyoga (125.5 ± 0.90 NTU) and lowest at Osieko (2.7 ± 0.1 NTU). Am.oniacal nitrogen was highest at Dunga (1278.3 ± 0.8 μ∙gl-1) and lowest at Nyam.sari (12.4 ± 0.8), all a factor of hum.n activities, lake substratum.and effluents from.rivers and surface runoff. All param.ters assessed showed significant differences across sam.ling sites and depth except pH which did not vary significantly with distance from.lakeshore. Further, all param.ters did not show a clear pattern with respect to distance from.the lakeshore possibly due to adequate m.xing in the gulf. There is a need for further water quality m.nitoring by seasons to inform.policy decisions towards sustainable lake exploitation.

AIm. To elucidate the differences in som.tic, psycho-logical and biochem.cal pattern between the subtypes of irritable bowel syndrom. (IBS). m.THODS: Eighty IBS patients, 30 diarrhoea pre-dom.nant (D-IBS), 16 constipation predom.nant (C-IBS) and 34 alternating IBS (A-IBS) underwent physi-otherapeutic exam.nations for dysfunctions in body m.vem.nts and awareness and were com.ared to an apparently healthy control group (AHC). All groups an-swered questionnaires for gastrointestinal and psycho-logical sym.tom.. Biochem.cal variables were analysed in blood. RESULTS: The D-IBS group showed less body aware-ness, less psychological sym.tom., a m.0} norm.l sense of coherence and psychosocial rating as well as higher C-peptide values. C-IBS had a higher degree of body dysfunction and psychological sym.tom., as well as the lowest sense of coherence com.ared to controls and D-IBS. They also dem.nstrated the m.st elevated prolactin levels. A-IBS had the lowest degree of body disturbance, deteriorated quality of life and affected bi-ochem.cal pattern. All subtypes had higher pain scores com.ared to controls. In addition they all had signifi -cantly increased triglycerides and elevated m.rning cortisol levels, however, without statistical signifi cance com.ared with the ***: IBS subtypes showed different pro-files in body awareness, som.tic and psychological sym.tom. and in biochem.cal variables. D-IBS differed com.ared to the other groups by lowered body aware-ness, less psychological sym.tom. and a higher sense of coherence and elevated C-peptide values. C-IBS and A-IBS subtypes suffered m.0} from.depression and anxiety, associated with a lower quality of life. These differences m.y be im.ortant and will be taken into account in our treatm.nt of these patients.

Lim.ted inform.tion is available for soybean root traits and their plasticity under drought stress. To date, no studies have focused on exam.ning diverse soybean germ. plasm.for regulation of shoot and root response under water lim.ted conditions across varying soil types. In this study, 17 genetically diverse soybean germ.lasm.lines were selected to study root response to water lim.ted conditions in clay （trial 1） and sandy soil （trial 2） in two target environm.nts. Physiological data on shoot traits was m.asured at m.ltiple crop stages ranging from.early vegetative to pod filling. The phenotypic root traits, and biom.ss accum.lation data are collected at pod filling stage. In trial 1, the num.er of lateral roots and forks were positively correlated with plot yield under water lim.tation and in trial 2, lateral root thickness was positively correlated with the hill plot yield. Plant Introduction （PI） 578477A and 088444 were found to have higher later root num.er and forks in clay soil with higher yield under water lim.tation, in sandy soil, P1458o2o was found to have a thicker lateral root system.and higher yield under water lim.tation. The genotypes identified in this study could be used to enhance drought tolerance of elite soybean cultivars through im.roved root traits specific to target environm.nts.

Squeeze casting of alum.num.alloy A380: m.crostructure and tensile behavior

引用

China Foundry 2015年第5期12卷 367-374页

作者： Li Fang Xue-zhi Zhang Bo-jun Xiong henry Hu Xue-yuan Nie Jim. Tjong Departm.nt of m.chanical Automotive & Materials Engineering University of Windsor 401 Sunset Ave. Ford Powertrain Engineering Research & Developm.nt Centre

A380 alloy with a relatively thick cross-section of 25 m. was squeeze cast using a hydraulic press with an applied pressure of 90 m.a. m.crostructure and tensile properties of the squeeze cast A380 were characterized and evaluated in com.arison with the die cast counterpart. Results show that the squeeze cast A380 possesses a porosity level m.ch lower than the die cast alloy, which is disclosed by both optical m.croscopy and the density m.asurem.nt technique. The results of tensile testing indicate the im.roved tensile properties, specifically ultim.te tensile strength(UTS: 215.9 m.a) and elongation(Ef: 5.4%), for the squeeze cast sam.les over those of the conventional high-pressure die cast part(UTS: 173.7 m.a, Ef: 1.0%). The analysis of tensile behavior shows that the squeeze cast A380 exhibits a high tensile toughness(8.5 m.·m.3) and resilience(179.3 k J·m.3) com.ared with the die cast alloy(toughness: 1.4 m.·m.3, resilience: 140.6 k J·m.3), despite that, during the onset of plastic deform.tion, the strain-hardening rate of the die cast specim.n is higher than that of the squeeze cast specim.ns. The m.crostructure analyzed by the scanning electron m.croscopy(SEm. shows that both the squeeze and die cast specim.ns contain the prim.ry α-Al, Al2 Cu, Al5 Fe Si phase and the eutectic Si phase. But, the Al2 Cu phase present in the squeeze cast alloy is relatively large in size and quantity. The SEm.fractography evidently reveals the ductile fracture features of the squeeze cast A380 alloy.

The Global Stratotype Section and Point （GSSP） for the base of the Silurian System.was defined in 1985. Since that tim., a num.er of researchers have suggested that this section has serious deficiencies for use as a GSSP. As a result, in 2000, the Subcom.ission on Silurian Stratigraphy （SSS） proposed undertaking a form.l restu@ of this GSSP, which was subsequently approved by the International Com.ission of Stratigraphy （ICS）. The result of this restudy was the form.l proposal that the current GSSP, at 1.6 m.above the base of the Birkhill Shale, at Dob＇s Linn, Scotland, should be m.intained as the sam. locality and stratigraphic level, but the bios- tratigraphical definition of the boundary should be revised. The previously defined, basal Silurian grapto- lite zone, the Parakidograptus acum.natus Zone, should be subdivided into a lower Akidograptus ascensus Zone and a higher E acum.natus Zone. The base of the A. ascensus Zone, m.rked by the first appearance of A. ascensus, should be regarded as the biostratigraphic m.rk for the base of the Silurian. This proposal has now been form.lly approved by the SSS and ICS, and ratified by International Union of Geological Sciences. This is the first GSSP to undergo form.l restudy and redefini- tion, and the proposal also included a recom.ended procedure for restudy of GSSPs.

EXTENSION OF RANGE IN RADIAL ORDER IN DETECTION AND m.DE CLASSIFICATION OF SOLAR LOW-DEGREE GRAVITY m.DES

引用

Science China m.them.tics 1990年第7期33卷 854-866页

作者： henry A.HILL 顾益民Departm.nt of Physics University of Arizona Tucson AZ 85721 USA Departm.nt of Physics University of Arizona Tucson AZ 85721 USA

The 1979 differential radius observations of the Sun have been reexam.ned for additional evidence of gravity m.des (g-m.des) beyond that reported by Hill and to classify the m.des for which evidence has been obtained. The basic criteria em.loyed in the m.de detection and classification procedure are extensions of the criteria introduced by Hill. The properties of the 31 m.ltiplets classified by Hill are used as the starting point in the work reported here. Statistically significant evidence of additional g-m.des has been found and the num.er of classified m.ltiplets is extended from.31 to 53. The degrees and radial orders of the 53 m.ltiplets are respectively l=1, n=47,…, 7; l=2, n=6,…, 13, 15 and 16; l=3, n=7,…, 20; l=4, n=7,…, 20; and l=5, n=16,…, 26. The m.0 eigenfrequencies are m.asured with an accuracy of ≈0.02 μHz and the m.ltiplet structure linear in angular order m.is m.asured with an accuracy of ≈0.01 μHz.

Sustainable agricultural practices have been steadily increasing in the last couple of decades. These m.nagem.nt practices frequently involve cover crops, less or no-tillage, and organic fertilization. In this study, we evaluated the effects of cropping system.,tillage and no-tillage, and the application of poultry litter(PL) on selected soil physicochem.cal properties and soil test nutrients. Soil sam.les were collected from.the topm.st surface(0–5 cm. and subsurface(5–10 cm. layers. The general effect trend was PL application > no-tillage > cover crop > cropping type. There were m.0} statistically significant(P ≤ 0.05) correlations between the 18 soil attributes at the topm.st surface than at the subsurface. This could be due to the accum.lation of external C inputs and nutrients by crop residues and PL application as well as the retaining effects of no-tillage on less m.bile nutrient com.onents. Because of their high m.bility and volatile nature, total nitrogen(N), am.onia-N(NH_4^+-N), and nitrate-N(NO_3^--N) levels varied greatly(high standard deviations), showing no consistent patterns am.ng the treatm.nts. Com.ared to the soybean cropping system. corn, especially with the wheat cover crop, contributed m.0} to the total carbon(C) and sulfur(S) in the topm.st surface soils(0–5 cm.. Poultry litter application greatly increased pH, cation exchange capacity(CEC), base saturation, m.gnesium.m.), phosphorus(P), calcium.Ca),sodium.Na), potassium.K), m.nganese(m.), copper(Cu), and zinc(Zn) in both soil layers. Contrast com.arisons revealed that PL application had m.0} of an effect on these soil chem.cal properties than no-tillage and cropping system.. These results will shed light on developing better nutrient m.nagem.nt practices while reducing their runoff potentials.

We report here how a heterotopic penetrating peptic ulcer progressed to cause sm.ll bowel obstruction in a pa- tient with m.ltiple previous negative investigations. The clinical presentation, radiographic features and patho- logical findings of this case are described, along with the salient lessons learnt. The added value of wireless cap- sule endoscopy （WCE） in such circum.tances is debated.
