THE DEVELOPMENT OF DUAL BAND DRA HYBRID ANTENNA

In wireless technology, Dielectric Resonator Antenna (DRA) is one of the recent technologies that are used to obtain an efficient performance in antenna. In this project a research has been done on the hybrid DRA whereby it consists of cylindrical dielectric resonator and micro-strip patch resonator. The design of the Dual Band Hybrid DRA is created and simulated using the Computer Simulation Technology (CST) software to achieve the desired bandwidth. Parametric studies of the proposed configuration were carried out to characterize the antennas and to verify the simulation result. The expectation of the dual band hybrid DRA is to obtain a wider bandwidth with an operating frequency range at 2.4 GHz to 2.6 GHz and 5 GHz to 6 GHz. To demonstrate the idea, the wireless area network (WLAN) within Industrial, Scientific, and Medical (ISM) band is used to design the Hybrid antenna

Transition of Care in Paediatric Surgery: Current practices and perspectives of paediatric surgeons in Malaysia

Objectives: Transition of care (TOC) from paediatric to adult care is still at an early stage in Malaysia. This study aimed to explore current practices and perspectives regarding TOC among paediatric surgeons in Malaysia. Methods: This study was carried out between June and December 2017. All 48 paediatric surgeons currently working in Malaysia were invited to participate in a questionnaire-based survey to assess demographic characteristics and practices and perspectives regarding TOC. Results: A total of 38 paediatric surgeons participated in the survey (response rate: 79.2%). Overall, 97.4% did not have an organised TOC model in their institution, with most (65.8%) caring for paediatric patients with complex surgical conditions until adulthood. Although the majority (86.8%) felt that care should be transitioned to adult surgeons with appropriate credentials, most surgeons (84.2%) nevertheless preferred to be involved in the management of adolescent patients after transition. However, there was no consensus regarding the most suitable age to begin the transition. Years of experience as a paediatric surgeon and place of practice did not affect overall TOC practice scores (P >0.050 each). The presence of adult comorbidities was considered the most common reason to initiate TOC (81.6%), while the lack of TOC guidelines was perceived to be the greatest barrier (84.2%). Conclusion: This study provides a better understanding of TOC from the point of view of paediatric surgeons in Malaysia. However, further studies involving other stakeholders (i.e. patients and adult surgeons) are needed to help formulate a suitable and successful TOC model in this setting.Keywords: Transition to Adult Care; Pediatrics; Adolescents; Surgery; Attitudes; Professional Practice; Malaysia

Hydrogeology of the eastern Ganges Basin: an overview

The Ganges Basin is a part of the Ganges-Brahmaputra-Meghna (GBM) River Basin and is one of the most populated (600 million) river basins in the world. This study focuses on the Eastern Ganges Basin (EGB) and covers India (Bihar, Jharkhand and West Bengal), Bangladesh and the Nepal Terai. Poverty is acute in the EGB, where household incomes are low, food security is not assured and devastating floods (and also water shortages) occur too often. The EGB is underlain by one of the most prolific aquifers in the world. Yet, farmers struggle to cope with dry spells and droughts because of their inability to access groundwater. Huge untapped groundwater, surplus surface water, and enormous plains and fertile lands highlight the requirement of proper planning for groundwater management and governance to reduce poverty and assure food security. The aim of this report is to assist planners/policymakers in the planning and management of groundwater resources in the EGB. This report mainly discusses about hydrogeology, groundwater potential and challenges, and groundwater quality issues in the EGB. Moreover, it is an attempt to form a base for future work related to groundwater development, management and modeling in this basin

Extent of arsenic contamination and its impact on the food chain and human health in the eastern Ganges Basin: a review

Exposure to arsenic and the use of arsenic-contaminated groundwater in agriculture causes serious health issues. Complete or partial contamination of groundwater is reported worldwide, especially in the Eastern Gangetic Basin (EGB). This study aims to create an overall assessment of arsenic contamination in the EGB based on existing literature, demarcate the extent of the affected area, highlight the impacts on the food chain and human health, and hopes the research will help in the better planning and management of groundwater. Although several studies have evaluated arsenic contamination of groundwater in the EGB, (a) there is no proper long-term monitoring being done in affected areas; (b) there is a debate to identify the exact source and transport processes of arsenic occurrence in this region; (c) there is no comprehensive method to estimate the level of arsenic contamination in soil, water and the food chain; and (d) Arsenic contamination in Bihar and Nepal is not evaluated systematically, especially arsenic accumulation in the food chain and human health issues. Data scarcity and accessibility are the major challenges in this region. Thus, this review recommends systematic monitoring and analysis of arsenic contamination in groundwater, soils and food across the EGB
