Software plays a major role in the present context. Therefore more and more software solutions are developed. These software solutions are hacked due to vulnerabilities available in the software. Most of these vulnerabilities are security-related. One of the key reasons behind this is the lack of security-related knowledge among the developers. Therefore it is important to assist them during the implementation stage. There are static analysis tools to assist them but these tools have a high concern on code quality and the architecture while having less attention for code security. Due to all these, it cost a lot during the maintenance phase to overcome the security-related issues. The suggested solution is a combination of three modules. Module one will rank the threats identified by the Microsoft Threat Modeling Tool in the design phase. Module two is an IntelliJ plugin which will assist the Java developers to maintain software security with respect to fifteen selected CERT guidelines. Module three will compare the design and the implementation while considering the inputs from the other two modules.

The “gold standard” for diagnosis of typhoid fever is the isolation of Salmonella typhi from appropriate samples including blood, stool and urine. The study was aimed to compare Widal test against stool culture for diagnosis of typhoid fever cases in Kano, Northern Nigeria. A completely randomized design is used. A total of 125 subjects (male, n= 57 and female, n=68) presenting febrile conditions in 4 different health care centers within Kumbotso Local Government Kano State were used for the study. About 5ml of blood was obtained from each study participant for Widal test and freshly passed faeces were collected for stool culture. The result showed that 22 (17.6%) tested positive for Salmonella typhi by Widal test, whereas 17 (13.6%) tested positive by stool culture. From the result, patients within the age category 21 – 40 years has the highest incidence 9 (7.2%) and 7 (5.6%) for Widal test and stool culture respectively while male has the highest prevalence with 12 and 10 individuals (9.6% and 8%) while 10 and 7 individual positive samples were female accounted for 8% and 5.6% for widal test and stool microcopy respectively. In relation to stool culture, Widal test has high sensitivity (78.3%), specificity (93.6%), positive predictive value (68.2%) and negative predictive value (98.1%). There is no significant difference on the prevalence of the infection on the basis of gender, age category and diagnostic methods at p<0.05. It is concluded that Widal test can be used as a diagnostic method for detection of Salmonella typhi.

Epoxy resin represents a commonly used basis for insulation materials and has been used in many different electrical applications. In this paper, different micro fillers such as Silicone dioxide (SiO2) and Barium iodate (Ba (IO3)2) were added to epoxy resin to improve electrical characteristics in different contaminated conditions. The electrical resistivity (ohm.cm) was carried out. The samples were prepared by mixing micro filler into epoxy with the content of 0, 5, 10, 15, 20 and 25 wt%. The artificial neural network (ANN) technique was used to evaluate electrical resistivity in different contaminated conditions and different fillers concentrations. The results show that the electrical resistivity of epoxy composites is increased with the increase of filler concentration. Maximum electrical resistivity (ohm.cm) value was obtained from micro Barium iodate composite with 25 wt% filler concentration.

: Addition of fillers to silicone rubber (SR) insulating materials has gained wide interest. Therefore, preparation of micro and nano composite materials will be helpful both for the users and manufacturers for improving electrical and thermal performances of insulators for high voltage applications. This paper deals with the experimental studies on the morphological, electrical and thermal characteristics of low weight % Zeolite (Z) filled nanocomposites and highly filled microcomposites. For the performance comparison breakdown strength and thermogravimetric analysis (TGA) test have been done on the SR specimens. Scanning electron microscopy (SEM) studies were conducted to understand the dispersion of the filler and the changes in surface morphology in both microcomposite and nanocomposite specimens. The results indicate that the electrical and thermal performances of microcomposites and nanocomposites are increased with the increase of filler concentration. Maximum breakdown strength value and TGA value were obtained from nanocomposite with 7 wt% filler concentration.

The content of this paper focuses on the stability analysis of embankment on soft ground by Plaxis software. Based on the results of actual monitoring of work incidents, make comparisons and recommend the use of the method.

In this paper, we contribute some new results on signed product cordial labeling and present necessary and sufficient conditions for signed product cordial in two cases:first ,the sum of the fourth power of paths with cycles and second, the union of the fourth power of paths with cycles.

Bangladesh, one of the world’s mostly densely populated countries, where former government of Bangladesh (Bangladesh Awami League (BAL), one of the political parties in Bangladesh, who formed the government in 2009 wanted to digitally develop the country by 2021. The plan of this development was one of the electoral manifestoes of the current Bangladesh government in 2008 before the ninth parliamentary election. This plan is widely known as “Digital Bangladesh – Vision 2021”. This slogan attracted whole nations (mainly young citizens) and as a result they have been given an opportunity for the alliance of ruling parties to rule the country with a conclusive victory. The aim of this paper is to introduce the concept and terminologies of “Digital Bangladesh”. This paper further aims to introduce main key elements/key outcomes of “Digital Bangladesh” concept.
