浅谈英语课堂的有效教学

提高课堂教学的有效性,精心设计生动的、富有情趣吸引力的、形式多样的活动。教学的有效性是教学设计的生命,是学校教学活动的一个基本追求,它直接关系到教学的质量和人才的培养。加强教师自身素质的提高是课堂教学的有效性的重要前提,教师本身的能力高低会直接的影响到课堂教学质量。     

马克思主义视域下人性的二重性解读

在人性的问题上,马克思主义之前的哲学往往用静止的、孤立的、片面的、抽象的、形而上学的思维方法来解读人性.马克思主义哲学以实践为出发点,运用辩证的思维方式,对人性作出了全新的二重性的解读,认为人性是全面的、发展的、辩证的,是矛盾的统一体,是能动与受动、客观与主观、具体与抽象、变与不变的统一,是一个系统的、开放的、复杂的有机整体.

电气自动化在钢铁企业中的应用策略

当代社会的科学技术是在不断的发展的,经济建设取得了巨大的成就,在这样的时代背景下对钢铁行业也提出了新的技术要求。这样其实在一定的程度上也推动了钢铁的快速发展。传统的电气工程的主要的组成部分是接触器和继电器等低压电气设备来进行实现的。随着科学技术的发展,传统的电气工程技术已经不能适应当今社会的技术要求。所以电气工程必须向着智能化、自动阿虎的方向发展,才能推动整个钢铁行业的自动化的改革。新型的综合化的创新型技术是需要结合智能化、自动化以及电气化等方面的控制手段这样才能在钢铁行业之中取得一个良好的钢铁运行结果,从而促进整个工业经济的全面发展。     

现代遥感技术在地质找矿中的应用

随着社会的不断进步以及经济的快速发展,我国的地质矿产业也得到了较快的发展,进而就在一定程度上对找矿的速率提出了更高的要求。而不断的将现代遥感技术应用在地质找矿的过程中,对于有效的提高找矿的效率以及准确度,以及不断的促进我国矿产业的发展都具有至关重要的作用。因此,我们应不断的分析与研究现代遥感技术在地质找矿中的应用,进而不断的改进与创新现代遥感技术,以此来有效的提高我国的找矿效率,进而不断的促进我国矿产业的稳定发展。     

晶体取向和极图测定

在冶金学研究和工程材料这两方面都应用了测定晶体取向信息的技术。机械和物理性能的研究,形变、再结晶和晶粒生长的研究,固态转变的研究,腐蚀速率的研究以及扩散的研究都常常包含有晶体取向的测定。另一方面,板材的塑性形变或磁性的各向异性这两者都起因于微晶的择优取向,对这一点的认识是控制这些材料的性能的基础。根据在深冲时会导致额外的不必要的修整和切头损失的制耳行为,形变的各向异性是明显的。通常,对磁性的各向     

冶金工程中机械设备的安装施工及维护探讨

随着西安代社会的快速发展,先进的科学技术的出现,改变了人们的生活方式,针对各个行业的发展情况,我们引进先进的技术和管理经验来更好的处理相关的工作,这样才能突破传统的建设,从而实现更好的发展.冶金工程中机械设备的安装施工和维护工作非常的重要,我们需要根据实际的发展情况来有效的解决其中各项问题,这样才能实现更好的发展.     

从两维视角探讨马克思主义关于人的本质理论

"人的本质是一切社会关系的总和",这是马克思对人的本质的科学论断.笔者认为人的本质是类本质和现实本质的统一.从人与社会的关系和人与自然的关系这两维视角审视人的本质,是符合马克思主义关于人的本质的理论观点的,这对进一步研究马克思主义人的本质理论及其把握有着重要的现实意义.     

马克思"人的解放"的科学内涵

在对人的存在形态和现实本质科学把握的基础上,马克思从三个角度论证了人的解放的科学内涵:一是人的解放的层次性,即类的解放、群体的解放和个体的解放的统一;二是人的解放的多维性,即人从自然力的盲目控制下获得解放、从社会关系的盲目控制下获得解放、从人自身的束缚中获得解放;三是人的解放的辩证性,即人的解放与社会进步的统一、无产阶级解放和人类解放的统一、崇高理想与现实运动的统一、统一性与多样性的统一.     

转炉炉壳热应力分析

根据实际转炉建立实体模型。以有限元为手段,考虑了炉衬和炉壳材料的物性参数随温度变化的特点和炉衬与炉壳之间膨胀间隙,计算了转炉炉壳在温度载荷和炉衬膨胀压力同时作用下的热应力。所得结果可为转炉炉壳设计提供依据。     

Quality of life of relatives of mental patients

Usage of quality of life of psychiatric patients' relatives as the parameter of estimation of the quality of psychiatric care is considered. By means of standard questionnaire elaborated by the authors as well as by means of both individual and group conversations the quality of life was analyzed in 40 relatives which lived together with psychiatric patients. Different spheres of their life and difficulties (financial, social-psychologic, production) were examined in families with such patients. The defects of psychiatric care that had direct influence on the quality of life of the psychiatric patients' relatives are outlined.     

Effect of antibiotics of chemotaxis of human leukocytes

The effect of 20 different antibiotics on chemotaxis by human neutrophils was studied. Human leukocytes incubated with chloramphenicol, rifampin, sodium fusidate, and tetracyclines in vitro showed markedly depressed migration. The mechanisms by which these antibiotics affect leukotaxis are discussed.

Concept of freedom of infection of animal flocks

Totally negative results of epidemiological investigation of random samples do not prove the absence of the infection as the pathogen may be restricted to only a few animals in the herd for a long time. The statement "absence of infection" is critical for such situations. The question is raised, whether the statement "absence of infection" should be generally avoided. Classification of herds and flocks according to the prevalence of the pathogen would be more valid for the implementation of control measures.     

The effect of amount of possession of the trait of hostility on accuracy of perception of hostility in others.

Some theories of personality hold that an individual's perception of others is influenced by his own personality characteristics; more specifically, that a trait of low social value will be projected more into others, and that insight into the possession of these characteristics reduces this distortion. These 2 hypotheses were tested by having a group of college students rate each other (including themselves) on degree of friendliness or hostility. Agreement with group rating about self yielded the insight score. In general, the hypotheses were supported; the "friendly" Ss were most accurate in their perception of others, and insight was positively associated with accurate perception.

Comparison of rates of infection of two methods of emergency ventricular drainage

The rates of infection of two methods of external ventricular drainage in use at Atkinson Morley's Hospital--namely, (a) percutaneous drainage with Rickham reservoirs and (b) tunnelled ventriculostomies--were compared in this retrospective review. Percutaneous drainage of CSF with Rickham reservoirs was associated with a 27% rate of infection as identified by positive microbiological cultures; tunnelled ventriculostomy catheters had a 10% infection rate. The difference in the infection rate between the two methods was statistically significant (P < 0.015). Other variables examined, including the age and sex of the patients and the reasons for ventricular drainage, were not associated with an increased rate of infection. Most infections from either method were caused by a coagulase negative staphylococcus. The average duration of ventricular drainage before identification of positive cultures was 5.7 days for Rickham reservoirs and 6.0 days for ventriculostomies.
