The energy contents of biogas could be significantly enhanced by upgrading it to vehicle fuel quality.A pilot-scale separation plant based on carbon hollow fiber membranes for upgrading biogas to vehicle fuel quality was constructed and operated at the biogas plant,Gl?r IKs,Lillehammer *** fuel quality according to swedish legislation was successfully achieved in a single stage separation *** raw biogas from anaerobic digestion of food waste contained 64±3 mol%CH_4,30–35 mol%CO_2 and less than one percent of N_2 and a minor amount of other *** raw biogas was available at 1.03 bar with a maximum flow rate of 60 Nm^3h^(à1).Pre-treatment of biogas was performed to remove bulk H_2O and H_2s contents up to the required limits in the vehicle fuel before entering to membrane *** membrane separation plant was designed to process 60 Nm^3h^(à1)of raw biogas at pressure up to 21 *** initial tests were,however,performed for the feed flow rate of 10 Nm^3h^(à1)at 21 *** successful operation of the pilot plant separation was continuously run for 192 h(8days).The CH_4 purity of 96%and maximum CH_4 recovery of 98%was reached in a short-term test of 5 *** permeate stream contained over20 mol%CH_4which could be used for the heating *** Hysys~?was integrated with Chem Brane(in-house developed membrane model)to run the simulations for estimation of membrane area and energy requirement of the pilot *** estimation was performed based on simulation data and later compared with actual field results.

AIM: To study if and how physicians use the irritable bowel syndrome (IBs) diagnostic criteria and to assess treatment strategies in IBs patients. METHODs: A questionnaire was sent to 191 physicians regarding IBs criteria, diagnostic methods and treatment. Furthermore, 94 patients who were diagnosed with IBs underwent telephone interview. REsULTs: A total of 80/191 (41.9%) physicians responded to the survey. Overall, 13 patients were diag-nosed monthly with IBs by specialists in gastroenterology (sGs) and 2.5 patients by general practitioners (GPs). All the sGs knew of the criteria to diagnose IBs, as did 46/70 (65.7%) GPs. seventy-nine percent used the patient's history, 38% used a physical examination, and 38% exclusion of other diseases to diagnose IBs. Only 18/80 (22.5%) physicians used specific IBs criteria. Of the patients interviewed, 59/94 (62.8%) knew they had experienced IBs. Two out of five patients knew IBs and had seen a physician because of IBs symptoms. Half of those received a diagnosis of IBs. A total of 13% were satisfied with treatment. IBs affected daily activities in 43% of cases. CONCLUsION: Half of the patients with IBs who consulted a physician received a diagnosis. Awareness and knowledge of diagnostic criteria for IBs differ between sGs and GPs.

It carried out a CRT monitor based psychophysical experiment to investigate the quality of three colour image difference metrics, the CIEΔE ab equation, the iCAM and the s-CIELAB metrics. six original images were reproduced through six gamut mapping algorithms for the observer experiment. The result indicates that the colour image difference calculated by each metric does not directly relate to perceived image difference.

It remains to be seen if the shift to less global engagement is an aberration or the new normal for U.s. foreign policy As the 75th anniversary of the UN, perhaps this is as good a time as any to discuss the United states’ role in the organization——particularly in light of President Donald Trump and his administration’s efforts to de-emphasize multilateral relations and global governance mechanisms.
