Oscillations in sea level due to meteorological forces related to wind and pressure affect the regular tides and modify the sea level conditions, mainly in restricted waters such as bays. Investigations surrounding these variations and the biological and chemical response are important for monitoring coastal regions mainly where upwelling shelf systems occur. A spatial and temporal database from quick Scatterometer satellite vector wind, surface stations from the Southeast coast of Brazil and surface seawater data collected in Anjos Bay, Arraial do Cabo city, northeast of Rio de Janeiro State were used to investigate the meteorological influences in the variability of the dissolved oxygen, nutrients, meroplankton larvae and chlorophyll-a concentrations. multivariate statistical approaches such as Principal Component Analysis (PCA) and Clustering Analysis (CA) were applied to verify spatial and temporal variances. A correlation matrix was also verified for different water masses in order to identify the relationship between the above parameters. A seasonal variability of the meteorological residual presents a well-defined pattern with maximum peaks in autumn/winter and minimum during spring/summer with negative values, period of occurrence of upwelling in this region. This lowering of the sea level is in accordance with the increasing of nutrients and meroplankton larvae for the same period. CA showed six groups and an importance of the zonal and meridional wind variability, including these variables in a single cluster. PCA retained eight components, explaining 64.10% of the total variance of data set. Some clusters and loadings have the same variables, showing the importance of the sea-air interaction.

针对动态翻译时指令和数据高速缓存访问负荷大幅增加且增幅不均衡导致翻译器性能下降的问题,提出基于指令高速缓存与数据高速缓存访问负荷动态均衡的软硬件协同翻译方法.该方法为处理器设计高速缓存负荷平衡状态,该状态将数据高速缓存分为普通区和负荷平衡区(load balancing area,LBA),普通区缓存正常的程序数据,负荷平衡区通过负荷转化通道(load transforming channel,LTC)吸收动态翻译器调度器地址空间转换操作在指令高速缓存上产生的部分负荷,以提高数据高速缓存利用率.EEmBC(embedded microprocessor benchmark consortium)测试基准实验结果表明,在同等处理器资源的情况下,该方法将指令高速缓存访问次数平均减少35%,数据高速缓存访问次数平均减少58%,动态翻译器综合性能提高171%.

The physicochemical degradation of Indigo Carmine (IC) dye in aqueous solution was performed using single and combined Advanced Oxidation Processes (AOP’s). Photocatalysis (TiO2-UV), Ozonation (O3) and Sonolysis (SN) were tested either in a standalone methodology or by combination of two simultaneous AOP’s. The dye conversion was followed by both measurements: 1) color removal determined by UV-VIS spectrometry and 2) organic and inorganic load determined by the chemical oxygen demand (COD). A complete and quick color disappearance of model water waste has been obtained by using combination of non-irradiated AOP’s, namely, O3/SN, which contrasts to the combination of irradiated photocatalysis with O3 or sonolysis. Color removal with simultaneous TiO2-UV/SN reached 77% while TiO2-UV/O3 reached 96% at similar reaction time. On the other hand, the standalone O3 yielded the highest color removal (94.4%) in 32 minutes whereas SN reached only 39.2% in 4 hours. The standalone light irradiated TiO2-UV reached 93.3% color re-moval in one hour of reaction time. These results indicated that non-irradiated (SN and O3) enhance synergistic effects that provoke structural changes in dye molecule without reaching total degradation. This is evidenced from FTIR of residuals from reaction mixture in which it has been observed the presence of organic molecules such as aromatics, sulfonic and amines refractory compounds that are mechanisti-cally possible to be found during IC degradation. Also, toxicity tests (microTox? Technique) were performed using commercially available bacteria culture before and after IC degradation for each AOP and their combination. Reduction of aqueous dye concentration decreased the level of toxicity of the treated water which is the main target of the AOP’s but the presence of the remaining recalcitrant compounds have also toxic effect.

This study was designed to screen and characterize antibiotic producing bacteria and fungi from soil samples from a waste dump site in Enugu. The molecular characterization of the isolates was performed by using Zymo Research quick-DNA fungi/bacteria miniprep kit. The bacteria isolates were Providencia stuartii, Providencia alcalifaciens. Bacillus sp., Streptococcus sp., micrococcus sp., and Staphylococcus sp while Aspergillus fumigatus and Aspergillus niger were fungal isolates. The efficacy of the Crude Extract (CE) of the antibiotics produced was tested against species of Staphylococcus aureus and Escherichia coli. The CE of antibiotics when compared with a conventional antibiotic (Ciprofloxacin) showed lower antimicrobial activity. The minimum inhibitory concentration of the crude extracts ranged between 12.5% and 25% concentrations while the minimum bactericidal concentration ranged from 25% and 50% concentrations. The findings suggest that these organisms have the potential to produce antibiotics and could be harnessed by pharmaceutical industries for the production of newer antibiotics.

Background: The non-contact specular microscope has become the method of choice for a quick, accurate and non-invasive assessment of central corneal thickness (CCT), which is an important variable to monitor before and after refractive surgery. The consistency of the results produced by such widely used methods/equipment must be assessed to determine their reliability. The purpose of this study was to assess within-and between-observer repeatability of, and to determine if a systematic bias exists in the measurements made by, the Topcon SP2000P specular microscope. methods: The CCT of the right eyes of 70 adult subjects, divided equally between men and women, was assessed on two separate occasions (4-7 days apart) by each of two examiners using the low-intensity auto mode of the SP2000P specular microscope. Results: The average CCT values formen and women,measured by one observer, were 0.52± 0.03 mm (mean± SD) and 0.52± 0.04 mm, respectively. The average for the entire sample was 0.52± 0.04 mm. Within-and between-observer repeatability were assessed by plotting the mean difference (for each subject) between two readings made by the same observer or one each by both observers against the combined average CCT reading of both sessions; the mean difference between two sets of observations was not significantly different from zero (P mits of repeatability were between-0.015 and 0.017 mm. For the second observer, the 95% limits of repeatability were between-0.018 and 0.018 mm. For the betweenobserver repeatability, the 95% limits of agreement were between-0.016 and 0.016 mm. For both within-and between-observer repeatability, we found no systematic bias of the mean difference with the average CCT reading. Conclusion: The withinand betweenobserver limits of agreement we found were similar to those previously reported for the Topcon SP2000P specular microscope; the range of the 95% limits of repeatability were within± 1 SD of the a

Background: Snakebite envenomation in pregnancy is uncommon. It can lead to a poor outcome in both the mother and the fetus. We describe our approach to envenomation in pregnancy based on the currently available evidence. Case: We reported two case of snakebite in the third trimester of pregnancy having caused placental abruption with expelling a fresh still born baby and a live baby. In both cases, consumption coagulopathy occurred. managed by polyvalent anti-snake and blood transfusion. Their investigations became normal and they were discharged of hospitalization. Conclusion: Snakebite envenomation in pregnant is a maternal and fetal emergency. Treatment must be quick and well adapted.
