It is widely observed that many physicians working in public health facilities do not put in the required effort and/or time in their jobs. At the same time, many public physicians remain highly motivated, working long hours for little financial reward in providing quality health services. This mix of providertypes poses fundamental challenges in the design of compensation mechanisms and monito...

Membrane separation systems require no or very little chemicals compared to standard unit operations. They are also easy to scale up, energy efficient, and already widely used in various gas and liquid separation processes. Different types of membranes such as common polymers, microporous organic polymers, fixed-site-carrier membranes, mixed matrix membranes, carbon membranes as well as inorgan...

Abstract This paper presents a model-based assessment of natural gas sweetening process combining high-pressure membrane contactor with conventional amine regeneration. The analysis builds on mathematical model the developed in companion paper, which is capable quantitative predictions CO2 and hydrocarbon absorption solvent evaporative losses to treated gas. predictive capability plant-wide tes...

In the current work, a framework is presented for amine solvent selection in gas treating process. Since the appropriate decision making in this field affects the capital and operational costs, multi attribute decision making (MADM) techniques were used to rank alternatives. The determination of criteria and alternatives is the most important aspect in the MADM. Criteria were divided into two c...

The development of germplasm with resistance to common scab and cold-induced sweetening is a high priority for the potato ( L.) industry. A mapping population was developed from mating two individuals of a diploid family generated by crossing the susceptible cultivated potato clone US-W4 to the highly resistant wild relative ( Bitter) clone '524-8'. Progeny were evaluated in replicated field tr...

Artificial sweeteners are food additives whose use has been controlled by European Parliament guidelines. The method described in this application note, shows how LC-MS/MS can be used to simultaneously detect and confirm the presence of several artificial sweeteners. The method is both quicker than conventional non LC-MS/MS methods and more sensitive. This has meant that these compounds can be ...

The present study is focused on biodesulfurization of natural gas in a batch culture using active microorganisms. The microorganisms used for the removal of hydrogen sulfide were obtained from a hot spring. The experiments were conducted with mixed gas at operating temperatures of 25 to 45°C with a time interval of 5h. Two kinetic models included Logistic and Monod models in a batch culture wer...

objective: despite the strong relationship between sugars, mutans streptococcilevels and caries, relatively, little research has been carried out on one of the factors that may influ-ence sugar intake; namely sweet preference. the objective of the present study was to ex-plore the association between sweet preference and the levels of dental caries in 6-12 year-old schoolchildren in hamedan. ma...
