The design and simulation patterns in ultrasonic wedges for non-destructive testing are critical to the assessment and characterization of a material or structure. Its significance is the mitigation of failures in members. The approach is relevant mostly to non-destructive testing of very expensive and critical mechanical members requiring high level of reliability in operation. In this paper, the design and simulation of ultrasound through both straight and angle wedges are discussed. Also, the characterization of the material using pulse-echo and through-transmission ultrasonic methods is illustrated.

Background: Increased prevalence and mortality of sepsis has been noticed in 20th, 21st centuries after successful implementation of global contraception, abortion in spite of newer antibiotics availability, improved health care provision and advanced technologies, protocols, strategies and policies of management; hence an altruistic retrospective analysis was planned to elucidate association between contraception and prognosis in severe sepsis.

The resuming of Brazil’s geopolitical process is part of a policy in international ascension of the country in search of affirmation to the emergence of a new world power hub in view of the current World Order context. It is still ongoing, in this sense, the repercussion of the theory of Brazilian political geographer Mario Travassos, published in 1930s, having a great impact on the South American continent, of the recovery through the formation of large territories throughout the country consists in Integration and Development (RIE), in which Amazon is highlighted by its strategic importance within what we call geographic systems. These lines will be superimposed on the formation of these large areas. On the interpretation of these facts, one has as a goal to understand spatial systems logic within Travassos and geopolitical perspectives, considering the axes of Integration and Development EIDs in Northern Frontier inside current Brazilian Geopolitics Perspectives. Therefore, understanding the Amazon key role in the geopolitical scenario correlate and interpreting the constitution of borders and territorial policies of Travassos’ EID theory with a current perspective and at the same time, demonstrate the current geopolitical framework of the northern border and the pursuit of global projections of the country and at the same time understanding geopolitical functioning of the South American subcontinent. The methodology was based on an interpretive view of the facts and arguments made by reflections of the Research Group Geographical Studies (GPEG) and the literature review in the final results revolves around of Brazilian government rise and strategy based on geographical systems of Travassos’ theory.

For finding interesting patterns in large databases has lot of development in recent years.. Data mining is used in many fields like medicine, securing the data etc. Whereas bio data means the data regarding the biology, medical science, DNA technology and Bioinformatics in-depth analysis. Bio Informatics is the science which can perform managing, finding data, integrating, interrupting information from biological data, genomic, and metadata. Even additional knowledge and complexness can lead to the integration among genes. This paper is all about joining these two fields, the data regarding biology us ing data mining and gives the details of future developments in biodata analysis.

Background: More attention is needed in understanding the physical, social, and psychological impact of malocclusion on oral health-related quality of life since it provides more understanding of the demand for orthodontic treatment beyond clinician limits. The aim of this study was to assess the impact of orthodontic treatment needs on the oral health-related quality of life for dental students. Materials and Methods: A cross-sectional design was used. A random sample of 100 2nd years to 5th year dental students aged 17-23 years from the University of Medical Sciences and Technology in Sudan was obtained, and each subject was assessed for orthodontic treatment need using the Aesthetic Component of the Index of Orthodontic Treatment Needs by taking photographs of the dentition. Each subject was also given an Oral health-related quality to life questionnaire to complete: The Oral Health Impact Profile (OHIP) Results: In general, the oral health- related quality of life was good in this sample. Males generally showed a significantly higher OHIP scores in the handicap domain than females. (Pvalue: 0.003). Despite the fact that no significant gender differences were observed in the remaining quality of life domains, when the Aesthetic Component of the Index of Orthodontic Treatment Needs (IOTN-AC) was separately evaluated, it was found that males with borderline need for treatment had significantly higher impacts on oral health than females in the same group with regards to functional limitation and psychological discomfort, as well as overall OHIP scores (P= 0.014, 0.05, 0.000 respectively). Conclusion: Malocclusion does not appear to affect the oral health-related quality of life to a measurable degree.

A methodology of study of gear dynamics with the aid of the circuit theory and linear graph methods is presented. In terms of analogy of the force, electric tension is used for the composition of equivalent electrical circuit, which immediately gives the equations of motion. The application of the electrical analogy method for the automation of composition of equation of motion and their analysis are considered for the classical example of a one-stage gear transmission with flexible supports and coupling masses. This technique can be extended to analyse the dynamic characteristics of more complex dynamic systems as a planetary transmission with flexible supports.

Background: Cost-effective, safe and dependable central venous access is fundamental in the care of anpatients. This study sets out to compare the complication rates between electively insertedperipheral (PICCs) and central venous cathethers (CVCs) in operating theatres. Methods: A retrospective clinical audit was undertaken. Complications included in this study are: malposition events, thrombotic/thrombophlebitis, infectio n and dysfunctio n. Results: A total of 189 patients met the inclusion cr iteria. Malpositioning of the catheter tips and thrombotic/thrombophlebitic events more often occurred after PICCs insertion than CVCs. There was no statistical difference in the catheter associated infection and dysfunctio n rate for PICCs and CVCs. The highest number of complications occured in the first 7 indwelling days. Conclusion: This study highlights that the potential advantages of reduced expected cost- and labour- effectiveness of PICCs as traditionally perceived, may be inaccurate, and further awareness of complications associated with PICCs need to be considered.

Feeding time and regimen have the potentials to influence the performance of broiler breeder flocks and are thus of great importance. A literature review is presented concerning the responses of broiler breeders to feeding time and feeding regimen. There is a potential improvement in shell quality, egg weight and egg production that results from feeding later in the day ( afternoon feeding )or from splitting daily feed allocation (split feeding). Broiler breeders are usually given a limited daily feed allowance in the morning. This practice does not supply nutrients to coincide with the hen’s need.

The Fast Track Land Reform in Zimbabwe adversely affected environmental management. The study sought to establish the presence and functionality of institutions for rangeland management in Zimbabwe in Fast Track Resettlement areas. Data was collected using questionnaires and interviews. A total of 30 questionnaires were administered on each household, randomly selected to get their perspective on rangeland management issues. Key informants were also interviewed to understand the trajectories of rangelands management. Data from questionnaires was analyzed using the Statistical Package for Social Sciences (SPSS). Results revealed that there was a dearth of relevant institutions for the management of rangelands as a common property resource. It was concluded that lack of robust institutions, particularly in Fast Track Resettlement areas was at the core of rangeland deterioration. In order to enjoy the full benefits of the fast track land reform, robust technical support has to be availed to reduce environmental degradation taking place in the area.

Operation of modern wastewater treatment facilities (in the following: WWTP) are to a very large extent based on different forms of biological treatment. Historically a number of activated sludge models have dominated the market. The model that originally was developed during the second decade of the 20th century is often addressed as a suspended growth system as a contrast to attached growth models, such as trickling filters, rotating biological contactors (RBC:s) and more recently the moving bed biological reactors (MBBR:s). Regardless of the system chosen the biological stage in a modern WWTP represents the major energy consuming stage. The obvious exception for this statement is by convention the anaerobic treatment, especially used when the wastewater is a “high strength” stream, rich in hydrocarbonates. The sharpened demand on biological nutrient removal, especially nitrogen removal has even more highlighted the needs for an efficient process control.
