In developing countries like Bangladesh, self-medication has become a predicament associated with health risks and clinical complications. To date, no studies have been conducted on the practice of among indigenous population living in Chittagong Hill Tract (CHT).This study was aimed to determine prevalence analyzing factors it CHT.This cross-sectional from late October early December 2020; different group populations residing three districts CHT aged 18 or more. A pre-tested semi-structured...
Abstract Background Efficient healthcare delivery and access to specialized care rely heavily on a well-established sector referral system. However, the system faces significant challenges in developing nations like Bangladesh. This study aimed assess self-referral prevalence among patients attending tertiary hospitals Bangladesh identify associated factors. Methods cross-sectional was conducted at two hospital, involving 822 visiting their outpatient or inpatient departments. A...
The Long Term Evolution (LTE) standard is one of the most promising wireless access technologies for Machine to (M2M) communications because its high data rates, low latency and economies scale. M2M typically involves a large number autonomous devices sending traffic in coordinated manner (and possibly even simultaneously), therefore creating an uplink-heavy trend which needs efficient radio resource management scheme. conventional scheduling algorithms performance metrics are not suitable...
One of the major limitations LTE system in context Machine-to-Machine (M2M) communications is excessive control signalling required for dynamic scheduling radio resources. Although queue awareness and link adaptation features scheduler can be very beneficial M2M traffic as well, these two properties come at a cost significant overhead. In this paper, we propose an adaptive semi-persistent uplink which reduces overhead by level utilizes capacity efficiently to satisfy Quality Service (QoS)...
One of the key characteristics cellular Machine-to-Machine (M2M) communications is generation small data packets by a large number devices. The excessive control signaling required for dynamic scheduling such uplink in Long Term Evolution (LTE) standard impedes deployment LTE networks M2M communications. Traditional Semi-persistent (SPS) reduces load on channel but it currently only developed constant rate voice packets. For realistic environments, non-deterministic traffic needs to be...
Some M2M applications such as those found in a Smart Grid environment generate event driven and delay sensitive uplink traffic. Wide area cellular systems LTE are usually not optimized for In this paper, we design an scheduler with the main objective of maximizing percentage packets that satisfy their individual budgets. order to do accurately, allow devices notify eNodeB age oldest packet buffers via new MAC control element MPDU. This information is used by calculate absolute deadline each...
Dengue fever is currently a major global issue, especially in tropical and subtropical countries. The absence of specific antiviral medications supports alternative dengue treatment strategies. South Asian countries have been using Carica papaya leaves as traditional remedy for many years. possesses several biological features, including anti-inflammatory, antiviral, cancer-fighting, anti-diabetic, antioxidant qualities. Additionally, numerous studies demonstrated that bioactive compounds...
Large number of M2M devices are anticipated to be operating in future LTE networks which impose several system design challenges and wide range service requirements. The standard suffers from excess control channel overhead associated with radio resource allocation method for small, sporadic traffic per terminal is often the nature communications. rigid QoS support framework limited voice data services also fails address specific requirements classes. In this paper, we propose an adaptive...
M2M applications exhibit a wide variety of QoS requirements, but many, particularly those associated with monitoring and/or control, are delay sensitive and therefore have specific packet budgets. One the issues when supporting such over area cellular standard as LTE is that base station scheduling entity cannot precisely ascertain pending uplink packets at devices were generated. This makes according to deadlines based upon budgets very challenging ultimately involves some degree error. In...
A variety of scheduling strategies can be employed in wireless systems to satisfy different system objectives and cater for traffic types. Static persistent resource allocations transfer small M2M data packets efficiently compared dynamic packet-by-packet scheduling, even when the model is non-deterministic. Recently, adaptive have been proposed which volume allocated resources change sympathy with instantaneous queue size at device without expensive signaling on control channels. This...
The prominence of Machine-to-Machine (M2M) communications in the future wide area communication networks place various challenges to cellular technologies such as Long Term Evolution (LTE) standard, owing large number M2M devices generating small bursts infrequent data packets with a range delay requirements. channel structure and Quality Service (QoS) framework LTE fail support traffic multiple burst sizes QoS requirements while bottleneck often arises from limited control resources...
Abstract Wide area wireless systems conventionally employ dynamic scheduling for stochastic or bursty applications and persistent resource allocations of a given period deterministic such as voice. When considering machine‐to‐machine (M2M) from different markets, wide range allocation periods may be required to fully support the diversity applications. The set supported by system is compromise between efficient use available resources supporting many M2M possible. We consider two schemes:...
Abstract Two of the most important Jurassic reservoir units in offshore Abu Dhabi are characterised by intertidal to shallow marine carbonates that mainly comprise mud-dominated microbial bindstones (typically pervasively dolomitised) and peloidal/oolitic packstones grainstones likely represent small shoal systems developed seaward large tidal flats. Interbedded within these deposits cm-scale m-scale supratidal sabkha anhydrite layers. This combination facies results a wide range porosity...
