Abstract:

Point-of-use (POU) and point-of-entry (POE) devices are, in some situations, considered to be a viable solution for drinking water suppliers and consumers alike to deal with site specific drinking water issues. This paper introduces a newly developed decision support system (DSS) that employs decision making techniques to select among the various devices based on their characterization and sustainability assessment. Careful illustration of the various aspects and components of the DSS is provided and the decision process is explained. Aspects of validity, usability and sensitivity analysis are

Abstract The study examined two low-cost point-of-use water treatment systems developed in respect of bacterial and particulate removal when exposed to surface water for three months. Bacterial removal efficiency was estimated using E. coli and fecal coliforms, while particulate reduction efficiency was estimated by determining turbidity and total suspended solids (TSS). The systems investigated were the Gift of Water System (GWS) made in USA and the Drip Filter System (DFS) Model-JW-PD-1-70 made in South Africa. The study included seasonal water quality changes.

Abstract:

Point-of-use (POU) and point-of-entry (POE) drinking water treatment systems are gaining prominence, particularly from the point-of-view of technical appropriateness and consumer acceptance. They are becoming an increasingly viable alternative for small water treatment systems or in individual homes. However, sustainability concerns have been voiced in a number of studies investigating these devices. In this paper, sustainability is examined with respect to the fulfillment of treatment systems for a set of technical, economic, environmental and socio-cultural objectives. Consequently, the use

Abstract:

Ultraviolet (UV) irradiation is a common disinfection option for water treatment in the developed world. There are a few systems installed in developing countries for point-of-use treatment, but the low-pressure mercury lamps currently used as the UV irradiation source have a number of sustainability issues including a fragile envelope, a lifetime of approximately one year, and they contain mercury. UV light emitting diodes (LEDs) may offer solutions to many of the sustainability issues presented by current UV systems. LEDs are small, efficient, have long lifetimes, and do not contain mercury.

Rural China faces a shortage of safe drinking water. There are significant challenges associated with small centralized water supply systems and decentralized water supply systems. Many rural residents use point-of-use water treatment systems to ensure the safety of their drinking water.

Abstract:

AbstractThe work described is motivated by an inability to extend central infrastructure for power and water to low-population-density areas of the Navajo Nation and elsewhere. It is estimated that 35% of the Navajo population haul water for household use, frequently from unregulated sources of poor initial quality. The proposed household-scale, solar-driven nanofiltration (NF) system designs are economically optimized to satisfy point-of-use water purification objectives. The systems also provide electrical energy for a degree of nighttime household illumination. Results support rational desi

Abstract:

AbstractBleeding complications after cardiac surgery are common and are associated with increased morbidity and mortality. Their etiology is multifactorial, and treatment decisions are time sensitive. Point-of-care (POC) testing has an advantage over standard laboratory tests for faster turn-around times, and timely decision on coagulation intervention(s). The most common POC coagulation testing is the activated clotting time (ACT), used to monitor heparin therapy while on cardiopulmonary bypass. Viscoelastic coagulation tests including thromboelastometry (ROTEM) and thromboelastography (TEG)

Abstract:

Background: Adolescent substance use is a dynamic public health problem. Adolescence is a unique developmental period involving overlapping biological, psychological, and social factors which increase the rates of initiation of substance use. The developing adolescent brain is particularly susceptible to the effects of substances and most adults with substance use disorders began to have symptoms and problems in their adolescent years. Yet, for various reasons, most adolescents who use, misuse, abuse, or are addicted to substances do not perceive the need for treatment. Objective: Drug and alc

Abstract:

Aims: The aim of this research was to study health-related and sociodemographic determinants of the use of different complementary and alternative medicine (CAM) treatments in Europe and differences in CAM use in various European countries. Methods: The study was based on a design-based logistic regression analysis of the European Social Survey (ESS), Round 7. We distinguished four CAM modalities: manual therapies, alternative medicinal systems, traditional Asian medical systems and mind-body therapies. Results: In total, 25.9% of the general population had used CAM during the last 12 months.

Abstract:

The Houjing River watershed is one of the three major river watersheds in the Kaohsiung City, Taiwan. Based on the recent water quality analysis, the Houjing River is heavily polluted. Both point and non-point source (NPS) pollutants are the major causes of the poor water quality in the Houjing River. Investigation results demonstrate that the main point pollution sources included municipal, agricultural, and industrial wastewaters. In this study, land use identification in the Houjing River watershed was performed by integrating the skills of geographic information system (GIS) and global pos

Abstract:

One of the main advantages of predictive control approaches is the capability of dealing explicitly with constraints on the manipulated and output variables. However, if the predictive control formulation does not consider model uncertainties, then the constraint satisfaction may be compromised. A solution for this inconvenience is to use robust model predictive control (RMPC) strategies based on linear matrix inequalities (LMIs). However, LMI-based RMPC formulations typically consider only symmetric constraints. This paper proposes a method based on pseudoreferences to treat asymmetric output

As a reference point for this assessment, serves a conceptual framework of an “ideal type of treatment system”, which is built upon the following normative assumptions: the objective of harm minimisation or preventing substance-use-related consequences, evidence-based decision making, securing equity and accessibility also from a user perspective as well as efficiency in terms of th

Four systems were assessed in respect of metal, bacteria and particle removal when exposed to polluted river water with and without GAC. These were evaluated using fresh, wet preserved and dry preserved Southern African indigenous wood species. Initially, all filter systems with the following indigenous wood species Combretum erythrophyllum in System 1, Tarchonanthus camphoratus in System 2, Leonot

On-site wastewater treatment systems (OWS) are a potentially significant non-point source of nutrients to groundwater and surface waters, and are extensively used in coastal North Carolina. The goal of this study was to determine the treatment efficiency of four OWS in reducing total dissolved nitrogen (TDN) and dissolved organic carbon (DOC) concentrations before discharge to groundwater and/or adjacent surface water. Piezometers were installed for groundwater sample collection and nutrient analysis at four separate residences that use OWS. Septic tank effluent, groundwater, and surface water

Diabetes is not a single disease; it interferes with various systems in the body including nervous system and cardiovascular system. The therapeutic lines for type 1 diabetes start with insulin and will need another treatment such as metformin. On the other hand, type 2 diabetes treatment strategies start with metformin and there will be a need for another treatment, insulin according to the diseas

Abstract:

Objective Mesenchymal stem cells (MSCs) are a promising cell-based therapy treatment option for several orthopedic indications. Because culture expansion of MSC is time and cost intensive, a bedside concentration of bone marrow (BM) aspirate is used as an alternative. Many commercial systems are available but the available literature and knowledge regarding these systems is limited. We compared different point-of-care devices that concentrate BM (BMC) by focusing on technical features and quality parameters to help surgeons make informed decisions while selecting the appropriate device.
