A new methodology that enables us to compute the arbitrary shaped 3D crack problems is studied. In the present method, it is possible to analyze the 3D crack problems without preparing mesh data as in ordinary boundary elements but with defining a sequence of nodal points representing the crack front and the internal nodal points that define a crack surface as well as a shape function used for determining unknown variables. The present method has special potential for analyzing a complicated 3D crack geometry which is generally difficult to treat in usual element based methods. In the present research, we apply mesh-free body force method to analyze the growth of 3D planar cracks. In concrete, a crack growth analysis for initially rectangular or elliptical crack existing in an infinite solid under uniform tensile stress perpendicular to the crack surface at infinity is demonstrated

All over the world currently there are billions of people who use tobacco regularly that’s why now these days the tobacco is one of the most widely used drug. Many of scientific evidences reveal that tobacco is dangerous to human health. Tobacco contains plethora of harmful chemical substances, out of which many of them are carcinogens. Smoking is responsible for 90% of all lung cancer and mouth cancer, 75% of chronic bronchitis and emphysema and 25 % of ischemic heart disease cases so tobacco is one of the leading preventable causes of deaths. In consideration of all these factors this review discusses various aspects of these electronic cigarettes like their structural components, working mechanism and their role in smoking cessation. E-cigarettes now gained a lot of popularity. This review also helps to aware health care professionals along with general population about the safety, myths, future challenges and about all pros and cons of using E-cigarettes.

Abstract. Coronary artery disease (CAD) is the leading cause of morbidity and mortality in the industrialized countries. Assessment of symptomatic patients with suspected obstructive CAD is a common reason for a clinical visit. Noninvasive anatomical and functional imaging are established tools to rule-in and rule-out CAD, to assess the severity of disease and to determine the potential risk of future cardiovascular events. In this review, we discuss the updated Guidelines from the European Society of Cardiology on Chronic Coronary Syndromes and explore the different imaging modalities used in current clinical practice for the noninvasive assessment of CAD. The pros and cons of each method, especially comparing anatomical and functional testing, are presented. Furthermore we we address the practical clinical aspects in the selection of the optimal noninvasive tests according to clinical need.

Abstract. Content analysis is a late and contentious addition to the Rorschach canon. The determinants have ruled. Hermann Rorschach was at best, ambivalent about content analysis, focusing on the perceptual aspects of the process. Rorschachers have been not been conTENT about CONtent. The literature on the pros and cons and the how-to of content analysis is reviewed chronologically, concluding with eight issues and objections that have left Rorschach practitioners malcontent with content. Hoping to help practitioners improve the analysis of Rorschach content, ten suggestions, often with examples, are offered, these “hints” affecting both conceptualization and practice. A case fragment is appended to the review to host the above suggestions and to illustrate the (likely) less frequent “active evocation” of content to further the analysis.
