BACKGROUND: Aluminum phosphide(Al P) poisoning is common in the developing countries. There is no specifi c antidote for the treatment of acute Al P poisoning. Early diagnosis of poisoning and outcome predictors may facilitate treatment decisions. The objective of this study was to determine the trend of blood lactate level in acute Al P poisoning to evaluate its role as a prognostic ***: This was a prospective study on acute Al P intoxicated patients during one year. Demographic data, clinical and laboratory data on admission, and outcome were recorded in a selfmade questionnaire. Blood lactate levels were analyzed every two hours for 24 ***: Thirty-nine(27 male, 12 female) patients were included in the study. The mortality rate was 38.5%. The mean blood pressure, pulse rate, blood p H and serum bicarbonate level were significantly different between the survivors and non-survivors groups. Blood lactate level was signifi cantly higher in the non-survivors group during 8 to 16 hours post ***: Blood lactate level could be used as an index of severity of acute Al P poisoning.

In the 1996 AIA （American Institute of Architecture） Convention in Minneapolis, the governing bodies in the education and professionalization of architects in the US （namely, the American Institute of Architecture, American Institute of Architecture Students, National Council of Architectural Registration Boards, National Architecture Accrediting Board and the Association of Collegiate Schools of Architecture） released the Boyer Report, subsequently published as Building Community： A New Future for Architecture Education and Practice. The report was named in honor of Ernest Boyer, an educational theorist who also participated in writing the text. Less comprehensive than the canonical texts by Marcus Vitruvius Pollio and his interlocutors, it is nonetheless a mirror of our current assumptions about the education of the architect. This paper looks at the epistemology inherited from Vitruvius as it shapes pedagogy up and through the Boyer Report and into the 21 st century. Using a method of comparative analysis applied to past and current architecture programs, our argument is that historical divisions between professional or applied knowledge and liberal or theoretical knowledge inherited from the past limit our capacity within architecture education to integrate new strategies for knowledge creation and dissemination. It is concluded that any serious revision of architecture education means a systematic reconsideration of the basis of architecture knowledge. What of the （persistent） Vitruvian model is relevant in our post-modern condition？ What do we learn from the image of our profession projected through the lens of the Boyer Report and it is like？ In other words, what would Vitruvius do？

阿塞拜疆的性别工资歧视

对女性的性别歧视是经济文献中讨论最多的话题之一。歧视表现在从家庭到经济各个层面以及生活的不同阶段。在过去的几年,人们对此已经采取有效措施并且相关国际组织和国家也接受了有关决议。但是,只有少数国家真正在为实现相对高标准的性别平等而努力着。全球的大部分地区,妇女在按照工作岗位获得报酬的同时也受到歧视,这就是所谓的“工资歧视”。并且全球都在讨论这个问题,甚至一些国家开始实施严格的政策抵制工资歧视,并确保工作场所女性的“同工同酬”。但是,在欧洲的一些国家,这个问题仍然是不可改变的,或者说改进是微乎其微的。在本文中,我调查了阿塞拜疆劳动市场对女性的工资歧视。阿塞拜疆在过去15年中经历了巨大的经济增长。尽管女性参与劳动力市场的比例越来越高,但工资差距仍然很大,随着国家工资的上涨而变得更大。这个问题从来都不是政府关注的焦点。缺乏实证研究同样是这个问题没有引起重视的原因。使用普通最小二乘法(OLS)和Blinder-Oaxaca分解方法我调查了阿塞拜疆的住户调查数据集,尤其是首都巴库。巴库是阿塞拜疆的主要经济中心,拥有全国近一半的人口。所以自然,劳动力和企业的基础也都在巴库得到沉淀。因此,巴库是进行个人调查并得出可信结论的最佳选择。我们发现阿塞拜疆存在对女性的工资歧视。此外,显而易见,教育程度明显影响性别工资差距,女性教育水平提高不会面临工资歧视。最后,结果显示,已婚女性在阿塞拜疆受到更多歧视。

Acta Geochimica 2019年第1期38卷 95-119页

The southern part of the Eastern Desert of Egypt—about 30 km southwest of Abu-Ramad city—is mainly covered by ophiolitic rocks(Sul Hamed), island arc assemblage, younger granites(muscovite granites of Qash Amer and two mica granites of El Sela), and various acidic and basic dikes. Field, petrological, and geochemical studies indicate that the El Sela shear zone has been subject to hydrothermal and supergene alteration such as kaolinization, albitization, sericitization, and hematitization. It is invaded by quartz ENE–WSW veins associated with hydrothermal alteration accompanied by radioactive mineralization. The investigated younger granitic rocks had very low contents of compatible elements, such as Cr, Ni,and Co; and high contents of incompatible elements, such as Zr, and large ion lithophiles, such as Sr, especially in the El Sela shear zone. Major oxide and trace element analyses revealed calc-alkaline affinity and peraluminous *** highly differentiated granitic rocks' lower Zr/Hf and higher Y/Ho than the normal ratio are consistent with hydrothermal alteration. Most samples had rare earth element(REE)-patterns with an M-type tetrad effect in the first and fourth segments and a W-type tetrad in the third segment. The average ∑REE in the studied granites was lower than the world granite average; the ratio of light to heavy REEs greater. The main radioactive, uranium-bearing, and uraniferous Fe and Mn minerals are uranothorite,autunite, uranophane and autunite as compounds, kasolite,columbite, xenotime, uranophane-bearing zircon and jarosite, silver-bearing pyrite, hematite, and autunite-bearing pyrolusite.

·AIM: To assess main indications, postoperative complications and clinicopathological correlation of ocular enucleation-evisceration.·METHODS: A total of 107 subjects who underwent enucleation and/or evisceration and received hydroxyapatite implants(Scleral wrap or mesh) were assessed. For each patient clinicopathological data was collected which included demographic information,clinical history, primary clinical diagnosis, main cause of ophthalmic surgery(traumatic, non-traumatic), type of surgical procedure(enucleation, evisceration) and pathological report. Patients’ postoperative clinical visits were checked for procedure-related complications during first year after surgery.·RESULTS: One hundred and seven patients(male:65.4%; mean age: 26y) underwent enucleation(n=100) or evisceration(n =7) due to traumatic(n =41) and non-traumatic(n =66) causes. Disfiguring painful blind eye was the most common indication of surgery(66.4%),followed by leukocoria(19.6%) and endophthalmitis(4.7%). The main types of injury included firecracker,traffic and work accidents, and sharp object perforating injury. In 53(80.3%) subjects in non-traumatic group the initial clinical diagnosis matched the histopathologicalresults. Malignant tumors(retinoblastoma: 47.5%,malignant melanoma: 27.3%) were the most common pathological diagnoses followed by phthisis bulbi(25.8%).The most common procedure-related complications were major eye discharge(39.6%), and implant exposure and discharge(20.8%).·CONCLUSION: Trauma and malignant tumors are the leading causes of enucleation-evisceration. Despite developing new techniques and materials, enucleation is still associated with considerable postoperative complications.

In this study, 9 nm superparamagnetic iron oxide nanoparticles (SPION) were functionalized by polyamidoamine (PAMAM) dendrimer. Using tetracholoroauric acid (HAuCl4), magnetodendrimer (MD) samples were conjugated by gold nanoparticles (Au-NPs). Two different reducing agents, i.e. sodium borohydride and hydrazine sulfate, and pre-synthesized 10-nm Au-NP were used to evaluate the efficiency of conjugation method. The samples were characterized using X-ray diffractometry (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, UV-visible spectroscopy and fluorescence spectroscopy. The results confirmed that Au- NPs produced by sodium borohydrate and the pre-synthesized 10-nm Au-NPs were capped by MDs whereas the Au-NP prepared by hydrazine sulfate as a reducing agent was entrapped by MDs. Optical properties of the MDs were studied by laser-induced fluorescence spectroscopy (LIF) within a wide range of visible spectrum. Also, based on the thermal analysis, all synthesized nanostructures exhibited a temperature increase using 488 nm and 514 nm wavelengths of a tunable argon laser. The new iron oxide-dendrimer-Au NPs synthesized by sodium borohydrate (IDA- NaBH4) produced the highest temperature increase at 488 nm whereas the other nanostructures particularly pure Au-NPs produced more heating effect at 514 nm. These findings suggest the potential application of these nanocomposites in the field of bioimaging, targeted drug delivery and controlled hyperthermia.
