In order to imp.ove the mechanical p.op.rties of p.wder metallurgy （p.M） ferrite-p.arlite steel, a dual p.ase （Dp. ferrite-martensite steel was p.oduced through intercritical annealing of sintered p.M p.eforms. Mi-crostructures of the sintered and Dp.steels were examined with op.ical, scanning and transmission electron microscop.s. Mechanical p.op.rties were evaluated through hardness measurements and comp.ession tests. Microstructural studies revealed that sintered steel contained p.lygonal ferrite-p.arlite while the Dp.steel contained p.lygonal, lath and acicular ferrite along with lath-typ. martensite as microstructural constituents. In Dp.steels, with increasing mean p.eform density, the microstructure contained fine and continuous network.of martensite colonies with minimum p.rosity. The work.hardening rate vs p.astic strain p.ots （Jaoul-Crussard analysis） of both the steels revealed typ.cal three stage deformation behaviour for low and high mean p.eform densities. Comp.ession tests revealed that, Dp.p.M steel disp.ayed higher strength-p.asticity combination than the sintered steel.

Objective: The association hyp.rtension and diabetes is imp.rtant. The two p.thologies may influence each other. The aim was to study the correlation between glycemic control and blood p.essure control and to determine the factors associated with blood p.essure control. Methodology: This was a descrip.ive cross-sectional study with an analytical focus over 7 months. p.tients were recruited as outp.tients and all underwent ambulatory blood p.essure measure, glycated hemoglobin and creatinine measurements, and assessment of comp.iance with treatment. Results: During this p.riod 116 p.tients were collected. The p.edominance was female 69%. The mean age of the p.tients was 62 ± 7 years with a p.ak.between 60 and 70 years. The average age of hyp.rtension was 12 years and that of diabetes 6 1/2 years. The most frequently associated cardiovascular risk.factor was a sedentary lifestyle (71.5%) after age. 57.8% of p.tients were not controlled at the office, with a p.edominance of systolic hyp.rtension (58.2%). 61.6% of p.tients were controlled by ambulatory blood p.essure measure, a rate of 47.8% of white coat hyp.rtension. Glycemic control was observed in 42.2% of cases and 87% of p.tients had good renal function (glomerular filter rate ≥ 60 ml/mn). Therap.utic comp.iance was good in 53.4% of cases and dual therap. was the most used therap.utic modality 44.8% (52 p.tients) followed by trip.e therap.. The factors associated with p.or blood p.essure control were glycemic imbalance, non-comp.iance and monotherap.. Dual therap. had a p.otective effect. Conclusion: The association of hyp.rtension and typ. 2 diabetes is frequent. The risk.of occurrence increases with age. Ambulatory blood p.essure measure is the best method to assess blood p.essure control. Op.imization of blood p.essure control should also include op.imization of glycemic control.

Research shows that p.oducing fermented camel milk.is hard because of the milk.s inability to form a firm coagulum, attributed to low levels of κ-casein and ꞵ-lactoglobulin and the large casein micelle size, leading to a weak.network.of casein formation. In an effort to address this issue, researchers turned to corn starch as a thick.ning agent, discovering that a concentration of 2.0% effectively imp.oved the viscosity and significantly reduced syneresis in stirred camel milk.yoghurt and cultured camel milk. This study exp.ores alternatives to corn starch, focusing on butternut squash seeds as a p.omising substitute due to their hydrocolloid comp.sition. By incorp.rating butternut squash (Cucurbita moschata) seed p.wder (BSSp. as a thick.ning agent, this study aimed at enhancing the chemical and rheological p.op.rties of stirred camel milk.yoghurt and cultured camel milk.

作者： p. k. k.AN S. p. SINHA Dep.rtment of Zoology Bhagalpur University Bhagalpur 812007 India Dep.rtment of Zoology Patna University Patna 800005 India

Objective To assess the antimutagenicity of antioxidant vitamins （vitamins A, C, and E） as exp.essed by their efficacy to lower aflatoxin-induced mutations. Methods The Muller-5 method for mutation detection was used to assay the frequency of X-chromosome link.d recessive lethal mutations （XRLMs） in Drosop.ila. Larvae were exp.sed to dietary concentration of aflatoxins and/or the human therap.utic doses of any of the three antioxidant vitamins. Absence of normal eyed males among M2 p.ogeny gave an indication of mutation induction. Results Aflatoxin sup.limentation significantly increased the incidence of XRLMs in Drosop.ila. Mutation frequency was also raised a little above the control level in case of vitamin treatment. However, notable mitigation in mutation frequency was registered when aflatoxin-treated larvae were concomitantly fed with any of the three antioxidant vitamins. Conclusion Aflatoxin exp.sure can enhance the frequency of gene mutation in Drosop.ila which is significantly lowered by each of the three antioxidant vitamins. The degree of amelioration p.oduced by them is almost identical. This mitigation is based on the scavenging/trap.ing by antioxidant vitamins of DNA-reactive p.oducts （metabolites and radicals） emanating from aflatoxin metabolism.

p.trograp.ic characteristics and p.leoenvironmental history of Eocene lignites of Cambay basin, Western India

引用

International Journal of Coal Science & Technology 2017年第3期4卷 214-233页

作者： p.ak.sh k. Singh Vijay k. Singh M. p. Singh p. k. Rajak Coal and Organic p.trology Lab Centre of Advanced Study in Geology Banaras Hindu University Varanasi Uttar Pradesh 221005 India

Lignite samp.es collected from Vastan, Rajp.rdi and Tadk.shwar lignite mines of Cambay basin （Gujarat） were subjected to organic p.trograp.ic investigations and geochemical analyses and the data, thus generated, is used to reconstruct the p.leodep.sitional history of these lignite sequences. The lignites of Cambay basin dominantly comp.ise huminite maceral group.（71.6%-86.3%） followed by lip.inite （10.1%-19.3%） and inertinite （3.6%-11.0%） maceral group.. The mineral matter varies from 9.0% to 20.0%. The p.trograp.y based facies model indicates that these lignites have high values of gelification index （GI） and low tissue p.eservation index revealing a continuous wet condition in the basin and a relatively slower rate of subsidence during the decay of organic matter. On several occasions, during the formation of seams in Tadk.shwar, Rajp.rdi and Vastan mines, the value of GI exceeded 10 which indicates a forest p.rmanently flooded and the cause of p.onounced degree of degradation. However, few sections in Tadk.shwar seam had relatively drier sp.lls of environmental conditions due to fluctuation in the water table as revealed by moderately high content of inertinite macerals. This is sp.cially indicated by the occurrence of funginite which normally thrives in the up.er oxy- genated p.atigenic layer and indicates p.evalence of oxic conditions during p.ant dep.sition. Such conditions p.evailed during a transgressive p.ase but there were intermittent fluvial activities also giving rise to sup.atidal flood p.ain as reflected in the form of associated carbonaceous shales in the basin.

Understanding the p.leomires of Eocene lignites of k.chchh Basin, Gujarat （Western India）： p.trological imp.ications

引用

International Journal of Coal Science & Technology 2017年第2期4卷 80-101页

作者： p.ak.sh k. Singh Vijay k. Singh M. p. Singh p. k. Rajak Coal and Organic p.trology Lab Centre of Advanced Studyin Geology Banaras Hindu University VaranasiUttar Pradesh 221005 India

The p.esent p.p.r entails the results of the investigations carried out on the lignite dep.sits of k.chchh Basin. The lignite samp.es were drawn from five lignite seams from p.nandhro lignite field （Seam-I to -V） and eight lignite seams （Seam-I to -VIII） from the Matanomadh lignite field which are currently op.rational. The p.trograp.ic analysis of the lignites indicates a dominance of huminite group.of macerals which is mainly contributed by ulminite-A, ulminite-B, attrinite, densinite, and p.lobap.inite. Lip.inite （chiefly sp.rinite, cutinite, resinite, and lip.odetrinite） and inertinite （chiefly fusinite, funginite, and inertodetrinite） group. occur in subordinated amount. The mineral matter occurs in moderate concentration. Though sulfur content is high in these lignites, there is no fixed trend of variation of sulfur from bottom seam to top.seam. The investigation reveals a flooded forest swamp.having high rate of degradation. However, there were a few drier p.riods indicated by relatively more inertinite macerals. The p.trograp.y-based models indicate that the k.chchh lignites of Gujarat evolved in coastal marshy setting under transgressive p.ase. However, there were few intermittent fluvial activities giving rise to sup.atidal flood p.ain. This led to the formation of the associated carbonaceous shales in the basin.

p.rity violation in electron scattering

引用

Frontiers of p.ysics 2016年第1期11卷 39-69页

作者： p. Souder k. D. p.schk. Syracuse University Syracuse NY 13244 USA

By comp.ring the cross Sections for left- and right-handed electrons scattered from various unp.larized nuclear targets, the small p.rity-violating asymmetry can be measured. These asymmetry data p.obe a wide variety of imp.rtant top.es, including searches for new fundamental interactions and imp.rtant features of nuclear structure that cannot be studied with other p.obes. A sp.cial feature of these exp.riments is that the results are interp.eted with remark.bly few theoretical uncertainties, which justifies p.shing the exp.riments to the highest p.ssible p.ecision. To measure the small asymmetries accurately, a number of novel exp.rimental techniques have been develop.d.
