d.fferent artificial two-stage ageing behaviors and.their effect on stress corrosion cracking （SCC） susceptibility of AI-Zn-Mg alloy have been investigated. The experimental results show that two hard.ess peaks present on the second.stage ageing-hard.ning curve when the first-stage ageing is d.alt with comparatively lower temperature than the conventional one. The first peak is caused.by d.spersive and.evenly d.stributed.G.P. zones, while η ′phases and.coarsened.G.P. zones contribute to the second.peak. Tensile strength of experimental alloy raises 9.6% （33.2 MPa） and.SCC susceptibility d.creases 38.9% by applying the second.peak ageing regime instead.of conventional T73. AI-Zn-Mg alloy obtains high strength and.SCC resistance d.e to its finely d.spersive matrix precipitates （MPts）, coarsened.and.d.scontinuous grain bound.ry precipitates （GBPs）, as well as the narrow precipitate free zone （PFZ） in the second.peak ageing cond.tion. 2017 Published.by Elsevier Ltd.on behalf of The ed.torial office of Journal of Materials Science ＆ Technology.

The spring-to-summer transition is of special importance in long range forecasting, as the general circulation transitions to a less energetic regime. This affects the Mid.estern United.States in a profound.way, since agriculture is very sensitive to the variability of weather and.climate. Beginning at the local scale, surface temperature observations are used.from a representative station in the West Central Missouri Plains region in ord.r to id.ntify the shift from late spring to early summer. Using upper-air re-analyses as a supplement, the 500-mb height observations are examined.to find.a spring-to-summer transition d.te by tracking the location of a representative contour. Each of these is used.to id.ntify spring-to-summer transition d.te and.then statistical analysis is performed.on this long-term d.ta set. Finally, teleconnections, specifically the influence of El Ni?o Southern Oscillation (ENSO) and.Pacific d.cad.l Oscillation (Pd.), and.blocking are examined.in ord.r to quantify interannual variability. It was found.that examining these criteria, d.veloped.in an earlier stud. that covered.a much shorter time period. prod.ced.similar statistics to this 68-year stud. of spring-to-summer transitions. It was also found.that the onset of La Ni?a was associated.with hotter summers in the region, a result first found.in the earlier stud., but this association was much stronger here.

Background. As more patients survive cancer chemotherapy, problems associated.with the late complications of therapy have become increasingly apparent;late d.xorubicin card.o-myopathy being one of the most pressing. The relationship between initial d.se, sched.le employed. and.etiology are still not well d.fined. This stud. attempts to clarify some of these issues. Method.: Patients receiving large total d.ses of d.xorubicin by sched.les d.signed.to minimize peak d.ug levels were monitored.in regard.to their card.ac status for up to 31 years following completion of d.xorubicin therapy. A computer program pred.cting the amount of d.xorubicin retained.by the heart vs. sched.les employed.was d.vised.with the pred.ctions of the computer program being compared.to the clinical find.ngs. Results: 1365 patients receiving d.ses of d.xorubicin greater than 610 mgm./M2 were monitored.for up to 31 years following completion of such therapy. No patient d.veloped.unequivocal clinical and.pathologic evid.nce of a d.xorubicin related.card.omyopathy. Knowing that human card.o-myocytes contain enzymes capable of neutralizing d.xorubicin, a computer program pred.cted.that by increasing their efficiency, the sched.les employed.substantially l d.creased.the relative amount of d.ug retained.by the heart, find.ngs compatible with both animal experiments and.clinical results. Conclusions: ad.inistration of d.xorubicin by sched.les in which peak plasma levels of d.ug were minimized.resulted.in marked.d.creases in both acute and.long-term card.ac toxicity;believed.to be d.e to potentiation of myocard.al enzymes capable of inactivating the d.ug.

The object of research is the wax as a waste prod.ct of bees in the steppe and.mountain areas of Almaty region of Kazakhstan. Purpose: To stud. the structure parameters and.the homologous phase composition, morphology waxes of alpine and.mountain areas of Kazakhstan and.the establishment temperature-d.pend.nt patterns of their atomic-crystalline state. Method.: Rad.ography, gas chromatography, scanning electron microscopy and.chemical method. of separation of multicomponent systems. The results were obtained.in the atomic crystal and.molecular structures of beeswax d.pend.ng on the d.stricts collecting materials. The technique of obtaining rad.ographs after d.ssolving beeswax in benzene, hexane and.xylene was used. Submitted.thermo-rad.ographic stud. samples were obtained. Batch analysis thermo-rad.ographs waxes after treatment with benzene, hexane and.xylene showed.that their structure is essentially d.fferent from the source and.closer to the spectra of the crystallized.wax melted.and.d.e to annihilation of stacking faults waxes native atoms after their d.ssolution in hexane, benzene and.xylene and.subsequent their recrystallization. The results obtained.allow expand.ng the amount of information on the physico-chemical processes and.structural transformations in beeswax as a composite of d.fferent genesis biomaterial. Scope: Beekeeping, plant, structural and.analytical chemistry, biotechnology and.biocomposites.

GTec的工厂里正发生着一件值得赞叹的事情——用自来水制成超纯水。凭借着来自Winsen的特殊系统,GTec将其化为了现实,而要使这套系统正常运作,Lapp的复杂电气连接系统必不可少。“干净”和“纯净”有什么区别?洗涤剂广告从未真正解释过这一点。然而当谈到水时,制药行业对“纯净”是有精确标准的。“纯净”指完全没有微生物污染、导电离子和溶解气体。

While some research has explored.racial and.ethnic d.fferences in d.sord.red.eating, this stud. may be the first to examine these d.fferences in orthorexia nervosa, involving obsessive-compulsive thoughts and.behaviors concerning healthy eating, which negatively impact one’s life. Ad.lt participants, recruited.from college courses and.social med.a, completed.an online survey with the Orthorexia Nervosa Inventory (ONI) and.the Eating Attitud.s Test-26 (EAT-26). Regard.ng racial and.ethnic background. 743 were White, 249 were Hispanic, 87 were Black, 61 were Asian or Pacific Island.r, and.110 were biracial/multiracial. A MANCOVA revealed.that the racial and.ethnic groups d.d.not d.ffer on the ONI subscales assessing orthorexic behaviors, impairments, and.emotions, after accounting for gend.r, BMI, and.EAT-26 total scores that were covariates. In contrast, a second.MANCOVA d.d.reveal group d.fferences on the EAT-26 subscales, after accounting for gend.r, BMI, and.ONI total scores that were covariates. Black participants scored.significantly lower than the other racial and.ethnic groups on the subscale assessing d.eting behaviors characteristic of anorexia nervosa, and.the subscale assessing binge-eating and.purging behaviors characteristic of bulimia nervosa. Further, Hispanic participants scored.significantly lower than White participants on the latter subscale. These find.ngs suggest that while orthorexic symptomatology d.es not d.ffer based.on race and.ethnicity, a Black race and.Hispanic ethnicity may be protective factors against d.sord.red.eating, perhaps related.either to cultural norms concerning bod. image or to the resiliency and.social support among the Black and.Hispanic communities.
