New Tools for Dengue Diagnostics

Dengue caused by four antigenically distinct serotype remains a serious health concern around the world, particularly in the tropical areas. Clinical signs and symptoms of this disease are indistinguishable from other infectious disease; therefore, laboratory diagnosis is very crucial for confirming the disease that will be useful for the patient’s management. In laboratory, dengue can be confirmed using cell culture, RNA detection, and serological detection based on ELISA and immunochromatographic test. However, each of these methods has certain practical limitations. Therefore, researchers from all over the world have been working to address these limitations. In this chapter, we will highlight the current research toward the development of novel point-of-care test for the diagnosis of dengue in acute and convalescent phase

Development of an Arduino Based Device for Early Detection of Gas Leakage in Hospitals & Industries

Leakage of gases in a system makes infrastructures and users vulnerable, it can occur due to its environmental conditions or old groundwork. Hospitals and industries where many types of gases are used like nitrogen, mono oxide, due to small amount of concentration in air can cause toxicity whereas detection of small amount of gas at its initial stage is very difficult task. Many systems have been developed which were failed in past to give accuracy in its implementation. In this research a portable detection system for the small leakage of gases has been developed, gas sensor (MQ-2) is used to find leakage when it is at its initial phase. The sensor and transmitting module senses the change in level of gas by using a sensing circuit. When a concentration of gas reach at a specified threshold level it will activate an alarm and sends a text massage to receiving module. The proposed system works well in hospitals, home, and industries

Smartphone use and academic performance of university students: a mediation and moderation analysis

The purpose of the undertaken study is to examine the influence of smartphones on the performance of university students in Pakistan. This paper also investigates the functions of a smartphone as exogenous predictors such as smartphone applications, multimedia messaging service (MMS), short message service (SMS), warp-speed processing, and entertainment on the academic performance of a student. This paper also addresses the impact of electronic word of mouth (eWOM) and attitude as mediating variables between exogenous and endogenous variables. Finally, we incorporated technology and addiction as moderating variables between independent variables and the outcome variable to measure the influence of moderating variables. We have taken 684 responses from seven universities in Pakistan and employed the SEM-based multivariate approach for the analysis of the data. The findings of this paper demonstrate that smartphone functions have a significant influence on students’ academic performance, and moderating and mediating variables also have a significant influence on exogenous and endogenous variables. The practical implications have provided a guideline for university teachers, parents, and decision-makers of how a smartphone could be used to improve student academic performance inside and outside university campuses
