Eleven onshore mud volcanoes in the southern region of Trinidad have been studied as analog habitats for possible microbial life on Mars. The profiles of the 11 mud volcanoes are presented in terms of their physical, chemical, mineralogical, and soil properties. The mud volcanoes sampled all emitted methane gas consistently at 3% volume. The average pH for the mud volcanic soil was 7.98. The av...

background pain management with the use of sedatives and analgesics has several advantages and few complications or side effects. objectives in this study, we planned to evaluate the effects of pain control on oxygen saturation independent of other factors, such previous cardio-pulmonary conditions or respiratory rate. patients and methods sixty-seven adult patients with direct trauma to extrem...

Abstract This work investigates the efficacy of a biodegradable natural product, litchi leaves powder (LLP) as filtration loss control agent in water-based drilling fluid formulations. In order to evaluate potential (LLP), strict protocol experimentations according API (American Petroleum Institute) standard has been followed. The experimental outcome showed that before hot rolling and after mu...

BACKGROUND Caesarean section (CS) rates are increasing worldwide and the most common reason is repeat CS following previous CS. For most women a vaginal birth after a previous CS (VBAC) is a safe option. However, the rate of VBAC differs in an international perspective. Obtaining deeper knowledge of clinicians' views on VBAC can help in understanding the factors of importance for increasing VBA...

BACKGROUND The use of acetylcysteine as a mucolytic agent is controversial. In 1962 it was claimed to be "the most effective agent ... for the liquefaction of ... secretions" but was subsequently taken off the market as a respirator solution. Normal saline, on the other hand, is becoming increasingly popular. A study was undertaken to determine which solution is more effective at clearing retai...

Optimization of drilling fluid parameters such as mud weight, salt concentration, and temperature is essential to alleviate instability problems during drilling through shale sections. The selection of suitable mud parameters can benefit from analyses that consider significant instability processes involved in shale-drilling–fluid interactions. This paper describes the development of analytical...

BACKGROUND Vaginal birth after Caesarean section (VBAC) is a relevant question for a large number of women due to the internationally rising Caesarean section (CS) rate. There is a great deal of research based on quantitative studies but few qualitative studies about women's experiences. METHOD A metasynthesis based on the interpretative meta ethnography method was conducted. The inclusion cr...

BACKGROUND In the absence of a HLA-matched related or matched unrelated donor, allogeneic stem cell transplantation (allo-SCT) from mismatched unrelated donors or haploidentical donors are potential alternatives for patients with acute leukemia with an indication to allo-SCT. The objective of this study was to compare the outcome of allo-SCT from T cell-replete haploidentical (Haplo) versus mat...

Clinical guidelines often make recommendations on the use of diagnostic tests. Compared with sensitivity and specificity, the use of preand post-test probabilities allows a more explicit and rational selection and interpretation of diagnostic tests. Ideally, clinical guidelines relating to diagnosis should routinely incorporate this information to enhance individualised decision making. We repo...

A genetic algorithm assisted minimum mean-square error (MMSE) multi-user detector (MUD) is proposed for a turbo-trellis-coded modulation-based space division multiple access aided orthogonal frequency division multiplexing system. The simulation results show that the system employing the concatenated MMSE-GA MUD was capable of achieving a similar performance to that attained by its optimum coun...
