Background:Before 2014(the year of closure of the two largest needle exchange programs in Hungary,which halved the number of available syringes in the country despite increased injecting risk practices)no HIV was reportedly acquired in Hungary among people who inject drugs(PWIDs)who were not also men who had sex with other men(MSM).In 2014,one and in 2015 two non-MSM PWIDs were newly diagnosed with HIV who supposedly became infected in Hungary,and both incident HIV cases in 2015 were diagnosed in the AIDS *** addition,two new(albeit supposedly imported)non-MSM PWID cases were also registered in the first three quarters of 2016,one of which subsequently was diagnosed with and then died of *** the same time,the prevalence of HCV doubled among PWIDs(from 24%to 49%in Hungary and from 34%to 61%in Budapest).Case presentation:The case that we discuss in this paper is a male PWID,who was diagnosed with HIV and AIDS in May of 2015 and then died of AIDS the next *** HIV infection status was detected with delay,and then appeared in the official statistics as an incident PWID HIV case and an incident PWID AIDS case,but not as an incident PWID AIDS *** contact tracing followed,even though it would have been relatively easy considering the *** our knowledge,no HIV post-exposure protocol exists in hospitals,in case of HIV exposure due to an eventual needle-stick ***:Our paper draws attention to recently published HIV and AIDS surveillance data,and shows the failure of the *** sounding the alarm based on three newly detected PWID HIV cases in the past 2 years may be premature,there are definitely serious problems in the HIV detection and tracing system among PWIDs in Hungary.

Journal of Animal Science and Biotechnology 2010年第1期1卷 15-24页

The objective of this study was to eval- uate the effects of inorganic phosphorus source and phytase addition on performance, nutrient digestibility and bone mineralization in broiler chick.ns. In Exp. 1,150 two-day old, male broiler chicks were fed a corn-soybean meal basal diet supplemented with phos- phorus provided by dicalcium phosphate, tricalcium phosphate or defluorinated rock phosphate. Five cages containing 10 birds were allotted to each of the three treatments. In Exp. 2,120 three-day old, male broiler chicks were fed the basal diet from Exp. 1 supplemen- ted with 0,250,500 ,or 1,000 P-＇rU phytase per kg of diet. Six cages containing five chicks were allotted to each of the four treatments. In Exp. 1, there was no difference in weight gain, feed intake or feed conver- sion as a result of feeding the different sources of in- organic phosphorus. The digestibility of phosphorus was significantly lower （P =0.01 ） for chicks fed di- ets supplemented with tricalcium phosphate than for chicks fed the other two diets. However, despite the lower digestibility, serum phosphorus levels did not differ among the three treatments. For Exp. 2, feedconversion showed a linear improvement （P = 0.03 ） with increasing levels of phytase inclusion （ days 0 to 33 ）. Phytase supplementation resulted in linear increa- ses in the digestibility of dry matter （P = 0.02 ）, crude protein （ P --- 0.04 ） and energy （ P 〈 0.01 ）. Chicks fed 1,000 FTU/kg phytase had significantly higher bone calcium （ P = 0.05 ） and bone break.ng strength （P = 0.04 ） than chicks fed the basal diet on day 33. In conclusion, the results of the current study indicated that the performance of birds fed diets sup- plemented with dicalcium phosphate, tricalcium phos- phate or defluorinated phosphate was similar and therefore production costs could be lowered by choo- sing the cheapest inorganic phosphorus source when formulating diets for poultry. When diets were formu- lated to meet dietary phosphorus requirem

In this paper,the dependencies of Young's modulus and attenuation decrement on samarium sulfide polycrystals(SmS)under various annealing temperatures are studied by the piezoelectric ultrasonic composite oscillator technique at a frequency of 100 kHz in the temperature range of 80-300 k.A decrease in Young's modulus with an increase of the annealing temperature due to the texturing of the material was *** the same time,attenuation peaks were observed at temperatures about 90 and 125 k,presumably due to niblett-Wilks and Bordoni relaxations.

用7级粒度分布的无铅焊料膏在60μm间距上最终生成30μm大小的沉淀,使得在整个面积阵列模式内获得焊膏印刷工艺。对于6级粒度分布的焊料膏,整个面积印刷被限制到在110μm间距上生成55μm大小的沉淀物。可是,用外围印刷模式,用6级焊料膏在90μm间距上生成55μm大小的沉淀物。由于模版印刷副工艺的不同,导致了在不同的几何学方面焊料膏级别行为的不同。6级焊膏有一种在60μm以上减小沉淀物尺寸的倾向性,这限制了在整个阵列范围内可获得的最小间距。另一方面,在这些几何学上的模板缝隙的6级焊料膏的释放优于7级焊料膏。这是因为超细颗粒焊膏加强沿模板缝隙的拉力。相反,7级焊膏能够填充最小的缝隙口,最小尺寸可达30μm,这样在同一小间距内产生整个阵列印刷模板。通过改善焊料膏设计和模板制造工艺可以改进模版印刷工艺。主要通过改变金属含量和焊剂类型可以成功地调整印刷工艺中超细颗粒几何形状焊料参数(剪切减薄、厚度和弹性)。这种行为与满足实际工艺条件的印刷参数,如印刷速度、压力、印刷距和分割速度紧密相关。而且,模版润滑方法的先进性形成了一种完美状态模板,用超细间距的润滑墙定义有形缝隙,因此,在每一种小尺寸上允许焊料膏释放。本文的重点是观察在6级和7级可粒度分配无铅焊料膏模板印刷工艺行为的副工艺和得到最小的间距和网络。比较了这两种颗粒分配焊料膏在副工艺中行为的区别。结论满足用无铅焊料膏可以产生超细小几何学的标准。而且,结论表明为了确定各自的应用几何学应该将6级和7级焊料膏分开用。
