solid superacid sO42-/ZrO2-siO2 was prepared by dip-impregnation method, and its catalytic activity was tested with esterification of p-nitrobenzoic acid and methanol. The optimum conditions were also found, that is, the molar ratio between silica and zirconia was 10：1, the calcination temperature was 550 ℃ and the soak.d consistency of H2sO4 was 1.0 mol.L-1. Under the conditions that the ratio of methanol to aeid（mL/ g） was 12：1, the amount of catalyst was 0.5 g, the reaction time was 5 h and the stirring speed was 800 ***-1, the yield of methyl p-nitrobenzoate could reach up to 90.5%. Then the characterizations of cataslyst, including the acidity and types of acidic centers, specific surface area and surface structure was respectively examined by Hammer indicator, in-situ pyridine IR, BET method, FT-IR（k.r）, transmission electron microscope （TEM）, and X-ray diffraction （XRD）. The results showed that the catalyst sO42-/ZrO2-siO2 was superacid with high specific surface area due to Ho〈-12.70. It contained acidic sites of Lewis and BrФnsted, and its surface structure changed after esterification. The zirconia crystal was mainly tetragonal and silica crystal was not found.

AIM: To examine the association between circulating 25-hydroxyvitamin D [25(OH)D] levels and colorectal adenoma in a case-control study and a meta-analysis. METHODs: We conducted a matched case-control study(112 cases and 112 matched controls) and combined 15 studies, including our study, in a metaanalysis. The study-specific odds ratios(ORs) and 95% confidence intervals(CIs) were pooled using a randomeffects model. In total, 5454 colorectal adenomas and 6656 controls were included in the meta-analysis. REsULTs: In a meta-analysis including 14 previous studies and our study, we observed a significant inverse association between circulating 25(OH)D levels and colorectal adenoma(OR = 0.68; 95%CI: 0.54-0.82) when comparing the highest category with the lowest category. stratification by adenoma location(proximal or distal adenoma) showed similar estimates. When we stratified by study region, the ORs(95%CIs) were 0.70(0.52-0.88) in the Us and 0.66(0.34-0.97) in Asia. CONCLUsION: These data suggest an inverse association between circulating 25(OH) Dlevels and colorectal adenoma in both Western and Asian populations.

The present study focuses on the quantification of mercury in sediment cores from Cocody, Banco, k.umassi and Milliardaires bays in Abidjan, Côte d’Ivoire. It aims at assessing the state of mercury contamination of the lagoon bottom using DMA-80 (Direct Mercury Analyser). The automatic analyzer DMA-80 mercury is an innovative instrument for the analysis of mercury at very low content in solid and liquid samples in five minutes, without requiring any prior steps of pretreatment wet. The results showed, according to the lithological description of different bays, that the cored sediments consist of mud, sand, sandy mud or muddy sand with occasional shells. In addition, our results showed the presence of mercury in the sediments of the lagoon bottom at a degree of contamination that varies from moderate to very high according to the calculated contamination factor (CF) values. The highest contamination was observed in Cocody Bay at the surface with a contamination factor of 7.5, while the lowest contamination was observed in Milliardaires Bay at the water-sediment interface with a contamination factor of 1.67. In addition, mercury concentrations compared to sediment guide values (sQGs) reveal that these sediments mostly show occasional biological effects but no toxicity except k.umassi core (sediments at 20 cm depth). Also, dredging, hydrodynamics have probably impacted the mercury content. The depositional environment of mercury metal is therefore a limiting factor for its fate in the aquatic environment.

AIM: To determine whether a newly developed respiratory rate monitor can practically and accurately monitor ventilation under propofol sedation in combination with standard monitoring. METHODs: Patients [American society of Anesthesiologists(AsA) Classification Ⅰ-Ⅲ] scheduled for elective colonoscopy under propofol sedation were monitored with a new device that measures the respiratory rate based on humidity in expired air. Patients with clinically significant cardiac disorders or pulmonary disease and patients requiring emergency procedures were excluded from study participation. All of the patients also received standard monitoring with pulse oximetry. This was a single-center study conducted in a community hospital in switzerland. After obtaining written informed consent from all subjects, 76 patients(51 females and 25 males) were monitored during colonoscopy under propofol sedation. The primary endpoint was the occurrence of any respiratory event(apnea or hypopnea). Apnea was defined as the cessation of breathing for a minimum of 10 s. significant apnea was defined as the cessation of breathing for more than 30 s. Hypopnea was defined as a reduction in the respiratory rate below 6/min for a minimum of 10 s. Any cases of significant apnea triggered interventions by the endoscopy team. The interventions included withholding propofol, verbal stimulation of the patients, and increased oxygen supplementation or the chin lift maneuver. A secondary endpoint was the correlation of apnea or hypopnea with hypoxemia(measured as a decrease in saO2 of at least 5% from baseline or less than 90%). REsULTs: At least one respiratory event was detected in thirty-seven patients(48.7%). In total, there were 73 respiratory events, ranging from one to six events in a single patient. significant apnea(> 30 s) occurred in five patients(6%). Only one episode of apnea led to a relative saO2 reduction(from 98% to 93%) after a 50 s lag time. No event requiring assisted ventilation was reco

Mand-Raigarh coalfield is one of the largest coalfields in the Mahanadi basin. The Geological survey of India carried out initial study primarily on exploration. However, detailed petrographic and geochemical characters of the coals have not been done so far. This investigation is an attempt for petrographic and geochemical appraisal of the coals. Moreover, effort is also made for possible interpretation on development of coal facies. The results drawn from 30 composite coal samples suggest coals are rich in vitrinite, with collotelinite as the dominant maceral while liptinite macerals register low concentration. Dominant mineral assemblages found were clay minerals, pyrite was recorded as disseminated, framboidal and euhedral forms, carbonates recorded were mainly siderites. The vitrinite reflectance random （VRo） mean values range from 0.44 % to 0.56 %, and the rank.of coal is suggested as.high volatile ＇B＇ to ＇A＇ sub- bituminous in rank. The rock.eval pyrolysis reveal TOC content varying from 37 % to 68.83 %, while low hydrocarbon generating potential is evident from low $2 and Tmax values. The Hydrogen Index （hi） versus Oxygen Index （OI） plot reveal that the samples belong to k.rogen type--II-III with input dominantly from terrestrial source, some samples also fall in k.rogen type--II domain indicating lacustrine input. Vitrinite reflectance result indicate that the samples are immature and approaching oil window, which is in agreement with data of the Rock.Eval parameters. The gelification index （GI） and tissue preservation index （TPI） indicate that the coal developed in a telematic set up with high tree density. The ground water index （GWI） and vegetation index （VI） demonstrate that the peat developed as an ombrogenous bog.

The research emphasizes on the relation of the Arabic concept of ＂ma＇ani nahwi＂ and the Latin ＂modistae＂. In order to establish this relation, the researcher illustrates the role of Aristotle＇s categories in influencing the concept of the Medieval Latin ＂modistae＂. This is followed by a reevaluation of the influence of Arabic philosophers, such as al-Farabi （c.870-c.950 CE）, Avicenna （980-1037 CE） and Averoes （c.1126-c.1198 CE） on Latin philosophy and linguistics, especially Jurjani＇s （d.1078 CE） role in introducing his concept of ＂nazm＂ towards ＂ma＇ani nahwi＂. The research contributes to the understanding of the relationship between syntax and semantics which has not been effectively clarified within the framework.of traditional Arabic grammatical theory.
