Non-compaction cardiomyopathy – brief review

Left ventricular non-compaction cardiomyopathy is a genetic disorder characterized by the presence of two myocardial layers with numerous prominent trabeculations and deep inter-trabecular recesses that communicate with the ventricular cavity. The diagnosis is often challenging because excessive trabeculations may also be a normal finding in performance athletes and black people. Echocardiography is the gold standard for diagnosis of this condition, but other useful diagnostic techniques may include cardiac magnetic resonance imaging, computed tomography, and contrast ventriculography. Moreover, newer echocardiographic methods such as three-dimensional imaging and speckle tracking analysis promise to improve the diagnosis of left ventricular non-compaction cardiomyopathy. The purpose of this paper is to review the pathogenesis, diagnosis, and management of this disease

STUDIES REGARDING THE DETERMINATION OF THE ADEQUATE ASSEMBLY TOLERANCES DEPENDING ON THE MANUFACTURING COSTS OF THE PARTS PROCESSED ON CLASSIC MACHINE TOOLS

The paper deals with a study case regarding the determination of adequate assembly tolerances. The study concerned the assembly of two bearings on an axle. Determining the adequate tolerances of the sizes chains is based on Lagrange’s multipliers use. The optimization criterion for determining the assembly tolerances is the minimization of the product achievement cost. The relation between tolerances and cost will be revealed in a graphic componen

SCHEME ANALYSIS TREE DIMENSIONS AND TOLERANCES PROCESSING

This paper presents one of the steps that help us to determine the optimal tolerances depending on thetechnological capability of processing equipment. To determine the tolerances in this way is necessary to takethe study and to represent schematically the operations are used in technological process of making a piece.Also in this phase will make the tree diagram of the dimensions and machining tolerances, dimensions andtolerances shown that the design execution. Determination processes, and operations of the dimensions andtolerances tree scheme will make for a machined piece is both indoor and outdoor

Serum testosterone and short-term mortality in men with acute myocardial infarction

Background: A significant and independent association between testosterone levels and coronary events in men and women has not been confirmed in large prospective studies, although some reports have shown that endogenous testosterone concentrations in men are inversely related to cardiovascular and general mortality. Methods: We aimed to assess the relationship between serum testosterone level and short-time (30-day) mortality in men with acute myocardial infarction. Results: We included 126 consecutive male patients admitted with acute myocardial infarction. The mean age was 62 ± 13 years. We determined, at admission, serum free testosterone (T) level (using a chemoluminiscence assay), high sensitivity C-reactive protein, N-terminal pro-B-type natriuretic peptide, and glycated hemoglobin level. We analyzed the 30-day mortality. Conclusions: The mean level of serum T was 4.1 ± 2.9 ng/mL. All non-survivors had T level ≤ 3 ng/mL. A low level of T was independently related to total short-term mortality. (Cardiol J 2010; 17, 3: 249-253

The Impact of Human Resource Management on the Competitiveness of Oil Companies in Iraq

The performance of human resource management, getting more importance and continuation with great dynamic competition. Human resource management performance is measured through more different indicators. It guarantees continuity of human resource management, to be competitiveness in the global marketplaces. Human resource management is the key for keeping the oil companies in a market competition. Human resource management needs to implement pre-planned goals. The study aims to study the impact of human resources management to implement the competitive strategy, to increase production, plan formulation support capacity companies on the efficiency and continuation, throughout skills, behaviors, training, regulation, directing, and observation

Planning Human Resources Management, Development and Training of Staff, and Their Impact on Organizational Performance, in the Iraq Oil Companies Sector

This paper aims to study the planning, training and development of human resources and its impact on the organizational performance of the Iraqi oil companies. Factors affecting HR planning, training and development were examined. The study population, composed of staff from the Human Resources Department of the Ministry of Oil, included 100 people surveyed. To achieve the objectives of the study, the researcher developed and distributed a survey and data collection and analysis using EXCEL. The overall analysis was carried out based on meta-statistics and correlation analysis. The results showed that human resource management, training and development planning are closely related to organizational performance in the Ministry of Oil. Paper presented recommendations for improving human resources in the Iraq Ministry of Oil

The Phenomenon of the Spread of Administrative and Financial Corruption in IRAQ Despite the Multiplicity of Oversight Bodies

The phenomenon of administrative and financial corruption is a serious phenomenon facing countries, especially developing countries and IRAQ in particular, as they began to decay in the body of their societies began to security and subsequent paralysis in the process of construction and economic development, which involve the destruction of the economy and financial and administrative capacity. The purpose of this study. To identify the manifestations of administrative and financial corruption in the country and diagnose and propose what can be proposed to address them and to ensure the reduction of its negative impact on development in terms of economic, social and administrative through the activation and consolidation of the efforts of the various bodies in the IRAQ
