The CO2 absorption and regeneration properties of this novel regenerable potassium-based dry sorbent were measured in a fixed-bed reactor during multiple absorption/regeneration cycles at low temperature conditions (CO2 absorption at 50-100 degrees C and regeneration at 130-200 C). The total CO2 capture capacity of the KZrl sorbent was maintained during the multiple CO2 absorption/regeneration cycles. The XRD patterns and FTIR analyses of the sorbents after CO2 absorption showed the KHCO3 phase only except for the ZrO2 phase used as support.

Even after 10 cycles, any other new structures resulting from the by-product during CO2 absorption were not observed. This phase could be easily converted into the this website original phase during regeneration, even at a low temperature (130 C). The KZrl sorbent developed in this study showed excellent characteristics in CO2 absorption and regeneration in that

it satisfies the requirements of a large Selleck HKI-272 amount of CO2 absorption (91.6 mg CO2/g sorbent) and the complete regeneration at a low temperature condition (1 atm, 150 degrees C) without deactivation. (C) 2008 Elsevier B.V. All rights reserved.”
“Background. Gestational diabetes is connected with fetal macrosomia and higher perinatal mortality and morbidity rates. The usually quoted literature, which causes so much anxiety among pregnant women and an increased number of cesarean sections, is often dated, from the times when pregnancy monitoring methods were not as highly developed as they are now, comes from heterogeneous populations, and does not take into consideration the age and ethnicity of women. Screening for gestational diabetes mellitus (GDM), diagnostic tests, and special programs for diabetic pregnant women are very expensive and time consuming. It is worthwhile then to try to evaluate their cost and see if reducing it would affect the clinical results.\n\nObjectives. The aim of this CB-839 study was to identify the real cost reduction and clinical advantages/disadvantages of replacing the 1-hr 50-g glucose challenge test (GCT) with the glucometer (stick method).\n\nMaterial and Methods. Two hundred and two

pregnant women from the population of this clinic attended screening for GDM by both enzymatic and stick method. The criteria for both measurements were the same. The positively screened women received a one-step diagnostic test and only they participated in the clinic’s diabetic program.\n\nResults. The results showed that replacing the enzymatic method by the stick method would reduce the total cost of screening for GDM by 90%. It was also calculated that the total cost of screening by this method followed by the diagnostic test would be 9.5 times lower than screening by the enzymatic method. It would have no harmful effects on perinatal outcome and would even make it possible to shorten the time between screening and treatment of GDM by about 7 days.\n\nConclusions.
