A pressure dependent Schrodinger equation is used to find the conditions that lead to superconductivity. When no pressure is exerted, the superconductor resistance vanishes beyond a critical temperature related to the repulsive force potential of the electron gass, where one assuming the electron total energy to be thermal, where applying mechanical pressure destroys Sc when it exceeds a certain critical value. However when the electron total energy is an assumed to be that of the free electron model and that the pressure is thermal and mechanical, the situation is different. The quantum expression for resistance shows that the increase of mechanical pressure increases the critical temperature. Such phenomenon is observed in high temperature cupper group.

A phenomenon known as trapped penis has numerous origins, including injudicious circumcision. Materials and Methods: Surgery for trapped penis with glanular amputation was performed for 5 children. The surgical policy in these cases included complete penile degloving, excising the scarring due to circumcission, fixing the penile skin at the penopubic and penoscrotal angles and reconstructing the penile skin with full thickness skin graft. Results: Improvement was noted in all cases. Conclusion: Surgery for hidden penis using full thickness skin graft achieves very satisfactory aesthetic and functional improvement.

Materials Sciences and Applications 2011年第8期2卷 1076-1082页

Cu-Ge ferrite was prepared using the standard ceramic method. The creep rate of polycrystalline Cu1+xGexFe2-2xO4 ferrite has been measured as a function of time at room temperature. It is found that the indentation length increases with the increase of both time and applied load. A regime of individual creep curves is observed for the first and second stages. It is not possible to record the third stage of the curve as usually happened in an ordinary creep test, because fracture of the samples does not occur. The slope is found to increase with increasing germanium and copper content in the steady state region. The high value of n (stress exponent factor) indicates that the dislocation creep is the dominate mechanism. The porosity arrangements developed within the specimens were examined using optical microscope. The results are discussed with regard to models describing the role of the steady state creep rate of metals. The morphology of the samples shows that the porosity is increased by increasing both copper and germanium ions.

在过去的十年中,大数据率的需求量不断增长,很多新方法也持续被引入。然而在当前存在的通信频带中,60GHz频段体现出了很多优势,比如连续带宽5GHz以下可以被使用。另外60GHz的无线电被看做为历史最大的授权带宽。尽管有这些优势,毫米波通信基地仍旧面临了很多必须解决的重大挑战。OFDM技术在60GHz频段无线电的应用激发了学术界极大的兴趣。这些系统的出现,带来了一系列的设计挑战,因为成功的设计必须经历多个设计过程,体验众多的转换。基于OFDM系统试图解决附带不同设计层次的要求这一重要背景,这一重大的设计是高度复杂的集成系统,其整体性能依赖于不同的组件规格的谨慎平衡,OFDM物理层和射频收发器需要被设计用来支持这些宽带和窄带的计划,以确保共存60GHz的设备,这项计划给予新兴应用大量支持,比如用于高质量无压缩视频流和快速的大文件传输。本文着重研究了OFDM基带处理系统60GHz无线电仿真,包括OFDM系统关键的模拟参数标识仿真。这将导致支持数据传输速率高达1.5Gbps的实现,同时本文提出了一种天线,并在可接受的成本下探索其所需的性能规格。整个系统将随后在Simulink中进行仿真,验证,合成并给60GHz OFDM硬件权限者提出一些设计考虑和实施中的问题。同时也展示了60GHz的通信系统一些未来所面临的挑战和未来的发展方向。

Introduction: In emerging countries where studies are rarer, the epidemiological profile of infective endocarditis resembles that of developed countries at the beginning of the antibiotic era. There is little data available in Mali on this subject, motivating this study, the aim of which was to study the etiological factors of infective endocarditis in children aged between 1 month and 15 years hospitalised in the paediatric department of the CHU Gabriel Touré. Patients and Methods: We conducted a cross-sectional and descriptive study, which took place from August 2018 to August 2019 (13 months), in children aged between 1 month and 15 years hospitalised in the paediatric department of the Gabriel Touré University Hospital with an ultrasound- confirmed cardiac disease and a temperature above 38°C. Results: The hospitalization rate was 0.4%. The average age was 11 months, the sex ratio was 1.35. Respiratory distress (63.6%) and fever (30.3%) were the most common reasons for referral. Congenital heart disease (87.9%) and dyspnoea on feeding (24.2%) were the most common medical histories. IVC was the most frequent congenital heart disease (36.4%). The mean temperature was 39.1°C. Blood cultures were taken in 24 patients (72.7%) and were positive in 27.3%. Staphylococcus aureus was found in 55.6% of cases. Trans-thoracic ultrasound found vegetations in 03 cases. According to the modified DUKE criteria, the diagnosis of endocarditis was retained in 27.30%. The evolution was marked by a high case fatality rate (45.45%). Conclusion: Endocarditis is an uncommon disease in children with a pulmonary portal of entry and Staphylococcus aureus as the main germ. Its mortality remains high.

在本文中,我们首次观察到氨基磺酸可以显著增强鲁米诺电化学发光,而且鲁米诺电化学发光的强度随着氨基磺酸浓度在0.1μmol·L^(-1)至500μmol·L^(-1)范围增加而线性增加。同时,我们观察到多巴胺可以显著猝灭鲁米诺-氨基磺酸电化学发光。基于该猝灭现象,我们建立了多巴胺的电化学发光分析方法,该方法的线性范围为0.5至20μmol·L^(-1),检出限为30 nmol·L^(-1)。该方法具有较好的选择性,尿酸、抗坏血酸、糖和一些氨基酸对电化学发光影响较小。采用标准加入法,成功地将鲁米诺-氨基磺酸体系用于尿液中多巴胺的电化学发光测定,回收率为103%~105%。另外,我们还考察了多巴胺的猝灭机理,并用Stern-Volmer方程计算了的动态猝灭常数。

AIM To evaluate the reversibility of minimal hepatic encephalopathy(MHE) following liver transplantation(LT) in Egyptian cirrhotic patients. METHODS This prospective study included twenty patients with biopsy-proven liver cirrhosis listed for LT and twenty ageand sex-matched healthy control subjects. All underwent neuro-psychiatric examination, laboratory investigations, radiological studies and psychometric tests including trail making test A(TMT A), TMT B, digit symbol test and serial dotting test. The psychometric hepatic encephalopathy score(PHES) was calculated for patients to diagnose MHE. Psychometric tests were repeated six months following LT in the cirrhotic patient group. RESULTS Before LT, psychometric tests showed highly significant deficits in cirrhotic patients in comparison to controls(P el for end-stage liver disease(MelD) score ≥ 15 was significantly related to the presence of post-transplant MHE(P = 0.005). More patients in whom reversal of MHE was observed had a pre-transplant MelD score elD score < 15.
