Spectroscopic properties of flashlamp pumped Nd^3＋：YAG laser are studied as a function of temperature in a range from-30℃ to 60℃. The spectral width and shift of quasi three-level 946.0-nm inter-Stark emission within the respective intermanifold transitions of ^4F3/2→^4I9/2are investigated. The 946.0-nm line shifts toward the shorter wavelength and broadens. In addition, the threshold power and slope efficiency of the 946.0-nm laser line are quantified with *** lower the temperature, the lower the threshold power is and the higher the slope efficiency of the 946.0-nm laser line is,thus the higher the laser output is. This phenomenon is attributed to the ion-phonon interaction and the thermal population in the ground state.

浮选药剂在黏土矿中基础矿物的选矿中表现出复杂的行为。利用中心组合设计法研究浮选药剂对低品位高黏质硫化物矿中铜浮选效率的交互作用。初步结果表明,在石灰作pH调节剂的情况下,异丙基黄原酸钠(SIPX)和O-异丙基-N-乙基硫基氨基甲酸酯(IPETC)是最有效的捕收剂。在不同的pH值下,评估捕收剂(SIPX和IPETC)用量和起泡剂甲基异丁基甲醇(MIBC)用量对分离效率的影响。基于方差分析(ANOVA)结果,对于分离效率而言,捕收剂用量与pH值以及捕收剂用量与起泡剂用量之间的交互作用显著。在低捕收剂用量时,pH值从9提高到11可使IPETC的铜分离效率从81%提高到86%,SIPX的铜分离效率从77%提高到86%。方差分析结果表明,在pH值11、8.6 g/t SIPX、7 g/t IPETC和20 g/t MIBC的条件下,铜分离效率最高(88.7%)。最终,可得出结论,捕收剂SIPX和IPETC更适合于处理高黏质硫化矿。

近年来氧化锆一直被应用于医学领域,如何获得优化、低成本的氧化锆磨削条件引起了工业界的关注。本文使用金刚石砂轮磨削部分稳定氧化锆(PSZ),以提高和控制其表面完整性、弯曲强度和磨削成本,并研究PSZ的相变和可研磨性。通过表面分析发现,所有经过磨削的样品表面完整性都有所增加,表面下100μm的表面损伤从3.4%降到了0.9%。弯曲强度试验表明,弯曲强度提高了29%以上,这是由于磨削获得了较高的表面完整性。用进行X RD表面分析发现,T-M相变趋势与表面完整性一致,即T-M相变可以提高弯曲强度和表面完整性。而且在最佳条件下,磨削成本降低了72%。因此,控制磨削PSZ中的磨削条件可以改善表面完整性和弯曲强度。利用响应表面法(RSM)建立数学模型来获得最优条件,发现进给量对输出的影响大于切削深度。

Multiobjective Programming (MOP) has become famous among many researchers due to more practical and realistic applications. A lot of methods have been proposed especially during the past four decades. In this paper, we develop a new algorithm based on a new approach to solve MOP by starting from a utopian point, which is usually infeasible, and moving towards the feasible region via stepwise movements and a simple continuous interaction with decision maker. We consider the case where all objective functions and constraints are linear. The implementation of the pro-posed algorithm is demonstrated by two numerical examples.

Objective: To compare Quanti-FERON-TB Gold In-Tube (QFT-GIT) test and tuberculin skin test (TST) for the diagnosis of latent tuberculosis infection in children. Methods: In this cross-sectional study, 64 participants who were between 3 months and 14 years old and had close contact with smear-positive pulmonary tuberculosis were included. Both QFT-GIT test and TST were done and the results were analyzed by SPSS software and Kappa test. Results: The distribution of gender and age according to QFT-GIT and TST results were matched (P>0.05). Overall agreement between QFT-GIT and TST for diagnosis of latent tuberculosis infection in children was 75%. In addition, the contingency coefficient was 0.257, and the Kappa measure of agreement was 0.246 (P=0.034). Conclusions: Compared to TST, QFT-GIT shows no apparent advantage for diagnosis of latent tuberculosis infection in children.

In this study, one hundred urine samples and one hundred blood samples of abusers were examined for the presence of alkaloid substances and abuse drugs in urines and bloods. These numbers of blood and urine samples referred who addicts in clinics of Welfare Organization, during of detoxification treatment or maintenance treatment were screened for abuse drugs presence. Age ranges of female patients were 35 ± 15 and age range of males patients were 42 ± 18. All patients filled questionnaire and satisfy forms too. All data were analyzed by t-test and were Anowa one way, and P < 0.05 was considered significant. The P value of this study was P = 0.000. In this study we conclude that among all drug analytical methods the cheapest and easiest test to screening opioids and other abuse drugs in urine and blood samples is strip test for rapid diagnosis and TLC (thin-layer chromatography) is appropriate confirmation method to drug abuse distinguishing. Also tests on blood samples have high importance as a view point of accuracy to distinguishing of drugs abuse.

AIM: To investigate the co-incidence of apoptosis, autophagy, and unfolded protein response(UPR) in hepatitis B(HBV) and C(HCV) infected ***: We performed immunofluorescence confocal microscopy on 10 liver biopsies from HBV and HCV patients and tissue microarrays of HBV positive liver samples. We used specific antibodies for LC3β, cleaved caspase-3, BIP(GRP78), and XBP1 to detect autophagy, apoptosis and UPR, respectively. AntiHCV NS3 and anti-HBs antibodies were also used to confirm infection. We performed triple blind counting of events to determine the co-incidence of autophagy(LC3β punctuate), apoptosis(cleaved caspase-3), and unfolded protein response(GRP78) with HBV and HCV infection in hepatocytes. All statistical analyses were performed using SPSS software for Windows(Version 16 SPSS Inc, Chicago, IL, United States). P-values 0.05). Furthermore, our evaluation of patients with HBV and HCV infection based on stage and grade of the liver diseases revealed no correlation between these pathological findings and induction of apoptosis, autophagy,
