碱尘暴期间松嫩平原西部碱尘气溶胶的主要元素质量浓度排序为Na、Al、Fe、Ca、Mg、K、Ti、Ba、Zn，与当地盐碱化土壤的元素组成吻合，而与沙尘、城市气溶胶的元素组成有差别。风力对碱尘气溶胶元素组成有明显的影响，当风速在8．0～17．1m／s时，元素组成的质量浓度排序为Na、Ca、Al、Fe、Mg、K、Ba、Ti、Zn。Na元素质量浓度的激增是碱尘暴元素组分的一大特征，明显富集元素为Na和B；相对于当地背景大气气溶胶的富集情况，Zn、Cu、Ba、B的富集因子值在碱尘暴期间明显降低；在各种天气情况下，B、Cu均具有较高的富集因子。碱尘中Ti元素的富集因子值均小于1，而Ca、Fe、K、Mg、Mn、Sr、V的富集因子值为1～4。两个采样点的Ca、Na、Al、Fe、Mg、Ti、Zn的富集因子近似，表明该区碱尘的主要元素具有特定的一致性；而B、Ba、Cu、V的富集因子相差较大，可以作为区分不同碱尘源的标志性元素。

With the prototype ECR ion source for the next carbon therapy facility in Japan a new series of measurements has been performed in order(a)to find the highest beam currents of C^(4+) ions,and(b)to study the effect of'special'gas-mixing by using a chemical compound as a feed *** isotopic effect has been found in a previous experiment:with deuterated methane(CD_4 gas) the C^(5+) beam currents are about 10% higher than with regular methane(CH_4 gas).For butane gases(C_4D_(10) and C_4H_(10) respectively)the isotopic effect for C^(5+) production is even stronger(>15%).For production of C^(4+) ions the isotopic effect appears to be *** turns out that the relative amount of carbon is much more important:acetylene gives 15% higher C^(4+) current than butane,which in turn gives about 10% higher C^(4+) ion currents than methane.

Background: Drug adherence decreased in patients with Parkinson’ s disease (PD) because of taking many different types of drugs. We evaluated drug adherence after switching from immediate-release (IR) to once-daily extended-release (ER) pramipexole (PPX) in PD. Methods: This study included 35 PD patients (20 men, 15 women);10 were taking oral PPX alone, and 25 were also using another anti-PD drug. PPX-IR was switched overnight to PPX-ER without gradual tapering. One month after switching, improvement in timing adherence and reduction in medication burden were evaluated by a questionnaire using a visual analog scale (VAS) (0: No change;10: Better). Motor function was assessed using part III of the Unified Parkinson’s Disease Rating Scale (UPDRS). Results: The VAS score for improvement in timing adherence was 8.1 ± 0.5 (mean ± standard error), and that for reduction in medication burden was 7.3 ± 0.6. There was a significant negative correlation (ρ = -0.43, p = 0.01) between the VAS score and number of types of medications. The UPDRS part III score improved significantly after switching

Hydrothermal process has been applied for effective production of Hydrogen from biowastes. In this study hydrothermal process for production of valuable Hydroxylapatitefrom chicken manure containing phosphorus was focused on. Conditions of 400?C and 26 - 27 MPa with addition of 1 mmol Ca(OH)2 were determined as the optimal by using O-phospho-DL-serine as a model compound. Afterwards, the real biowaste containing phosphorous, chicken manure was processed under the same conditions. Formation of a Hydroxylapatite;in the solid residue was confirmed from X-ray diffraction (XRD) patterns, after purification. It was found that 27.9% of P in the chicken manure was converted to Hydroxylapatite. With the use of acetic acid as a chemical purification medium, Hydroxylapatite was obtained.

This study proposes four possible energy supply chains from the megawatt class of photovoltaics (PV) installation in Kuala Lumpur, Kolkata, Beijing or Ulan Bator to end users in Tokyo Japan. In the proposed chains, the electricity generated from solar PV panels would be used to generate H2 through water electrolyzer. The H2 is then liquefied (or converted into organic hydride) and transported by tank truck for land as well as tanker for marine to Japan and finally supplied to fuel cells (FC) for power generation purpose. This study investigates the energy efficiencies of the proposed energy supply chain and the amount of CO2 emission in the transportation process from the four locations. As a result, it is found the largest amount of power could be generated in Ulan Batorthan in other cities with the same size of solar panel array, while it also emitted the largest amount of CO2 in the transportation process. The best energy efficiency is obtained in the case of Beijing. This study also revealed that the ratio of total energy consumption to calorific value of H2 after transportation in the case of H2 liquefaction is smaller than that in the case of organic hydride.

Cu-Zn-S (CZS) films were deposited by the spray pyrolysis method. As-deposited CZS film showed a low crystallinity. The resistivity of CZS film with Cu/(Cu+Zn) ratio of 50% is around 10-2Ω﹒cm. The CZS film elements using spray Cu-Zn (=1:1) solution with thiourea was confirmed as? Cu:Zn:Sn=2:2:3 by ICP-MS and EDX. The band gap of CZS films was varied in the range of 1.8 - 3.5 ev when the? Cu/(Cu+Zn)ratio was increased from 0 to 67%;CZS film with Cu/(Cu+Zn)ratio of 50 % showed an wide band gap of 2 eV. The photovoltaic characteristics were confirmed with cell structure of . The best cell was observed at the CZS films with Cu/(Cu+Zn)ratio of 50%;these cells depicted a conversion efficiency of 1.7%.

目的研究1-溴丙烷(1-BP)诱发大鼠性腺基因表达谱的变化,探索1-BP雄性生殖毒性相关的mRNA改变。方法雄性F344/NSIc大鼠12只,随机分为2组,分别吸入新鲜空气或5030mg/m31-BP8h。染毒后16h处死大鼠取出睾丸,运用大鼠性腺cDNA微阵列和real-timePCR方法测定1-BP染毒后性腺相关基因表达谱的变化。结果在大鼠性腺芯片5087个cDNA微点阵中,有62个基因被1-BP显著下调,3个基因显著上调。其中包括性激素合成相关基因细胞色素P450芳香化酶(CYP19a),谷胱苷肽S-转移酶(GSTT1),肌酸激酶(Ckb),髓鞘和淋巴细胞蛋白(Mal)和S100的钙结合蛋白(S100a4)。归类分析结果显示绝大多数变化的基因与蛋白质/脂类代谢相关,其次与应激防御反应相关。实时定量PCR证实了1-BP可引起CYP19a、S100a4、GSTT1和Mal的下调。结论急性高剂量染毒1-BP可引起睾丸组织CYP19a、S100a4、GSTT1、Mal等基因的下调,提示其可能通过内分泌干扰和氧化应激效应而导致雄性生殖毒性。

选择吉林西部两个典型地区,抽样采集碱尘样品,根据实测结果对日常形成的碱尘进行了通量测定;依据两个采样点的自然地理状况和实测采样记录,提出了吉林西部碱尘具有两种源区类型的认识,即以大布苏湖为代表的萎缩湖泡型和以姜家甸草场为代表的草场退化型。同时,通过对比分析不同时间和采样点的碱尘通量及源区特征,提出了吉林西部碱尘通量与风力条件、日照条件、pH值、物理性粘粒比例正相关,与植被覆盖度、地表物质粒级负相关。对碱尘元素分析结果表明,Ca、Na元素含量明显偏高,Fe、Al元素含量变化则较大;碱尘组成元素含量由多到少的顺序为:Ca、Na、Fe、Al、K、Mg、Ti,与普通尘暴元素组成有着明显的差别。
