São Paulo State has witnessed Co_(2)storage-based investigations considering the availability of suitable geologic structures and proximity to primary Co_(2)source sinks related to bioenergy and carbon capture and storage(BECCS)*** current study presents the hydrocarbon viability evaluations and Co_(2)storage prospects,focusing on the sandstone units of the Rio Bonito *** objective is to apply petrophysical evaluations with geochemical inputs in predicting future hydrocarbon(gas)production to boost Co_(2)storage within the study *** study used data from eleven wells with associated wireline logs(gamma ray,resistivity,density,neutron,and sonic)to predict potential hydrocarbon accumulation and fluid mobility in the investigated *** samples(shale and carbonate)obtained from depths>200 m within the study location have shown bitumen *** geochemistry data of the Rio Bonito Formation shale beds suggest they are potential hydrocarbon source rocks and could have contributed to the gas accumulations within the sandstone *** drilled well data,e.g.,CB-1-SP and TI-1-SP,show hydrocarbon(gas)presence based on the typical resistivity and the combined neutron-density responses at depths up to 3400 m,indicating the possibility of other hydrocarbon members apart from the heavy oil(bitumen)observed from the near-surface rocks *** the three-dimensional(3-d)model,the free fluid indicator(FFI)is more significant towards the southwest and southeast of the area with deeper depths of occurrence,indicating portions with reasonable hydrocarbon recovery rates and good prospects for Co_(2)injection,circulation and permanent ***,future studies based on contemporary datasets are required to establish the hydrocarbon viability further,foster gas production events,and enhance Co_(2)storage possibilities within the region.

Background： Leptin has a strong relation to important traits in animal production, such as carcass composition,feed intake, and reproduction. It is mainly produced by adipose cells and acts predominantly in the *** this study, circulating leptin and its gene expression in muscle were evaluated in two groups of young Nellore bulls with divergent feed efficiency. Individual dry matter intake（dMI） and average daily gain（AdG） of 98 Nellore bulls were evaluated in feedlot for 70 d to determinate the residual feed intake（RFI） and select 20 animals for the high feed efficient（LRFI） and 20 for the low feed efficient（HRFI） groups. Blood samples were collected on d 56 and at slaughter（80 d） to determine circulating plasma leptin. Samples of Longissimus dorsi were taken at slaughter for leptin gene expression ***： dMI and RFI were different between groups and LRFI animals showed less back fat and rump fat thickness,as well as less pelvic and kidney fat weight. Circulating leptin increased over time in all animals. Plasma leptin was greater in LRFI on 56 d and at slaughter（P = 0.0049）. Gene expression of leptin were greater in LRFI animals（P = 0.0022） in accordance with the plasma levels. The animals of the LRFI group were leaner, ate less, and had more circulating leptin and its gene ***： These findings demonstrated that leptin plays its physiological role in young Nellore bulls, probably controlling food intake because feed efficient animals have more leptin and lower residual feed intake.

The increasing volume of data in the area of environmental sciences needs analysis and interpretation. Among the challenges generated by this “data deluge”, the development of efficient strategies for the knowledge discovery is an important issue. Here, statistical and tools from computational intelligence are applied to analyze large data sets from meteorology and climate sciences. our approach allows a geographical mapping of the statistical property to be easily interpreted by meteorologists. our data analysis comprises two main steps of knowledge extraction, applied successively in order to reduce the complexity from the original data set. The goal is to identify a much smaller subset of climatic variables that might still be able to describe or even predict the probability of occurrence of an extreme event. The first step applies a class comparison technique: p-value estimation. The second step consists of a decision tree (dT) configured from the data available and the p-value analysis. The dT is used as a predictive model, identifying the most statistically significant climate variables of the precipitation intensity. The methodology is employed to the study the climatic causes of an extreme precipitation events occurred in Alagoas and Pernambuco States (Brazil) at June/2010.

However, combination of the extracts with Fluconazole potentiated the antifungal activity of this drug. At different experimental conditions, such as concentration of the extract and type of strain, the extracts inhibited hyphae and pseudohyphae formation, indicating that these fern species can affect the morphology of the ***: The extracts obtained from the fern species L. venustum and P. calomelanos dose not present significant antifungal activity. However, P. calomelanos potentiates the activity of fluconazole and both extracts inhibits the morphological changes in Candida species, indicating that they have potential pharmacological activity as modulators of fungal biology. Therefore, novel studies are required to characterize the interference of these extracts in the virulence and pathogenicity of Candida species as well as the potential of fern species to treat fungal infections.

The present study was carried out to evaluate the survival rate of four tropical legume seeds submitted to different periods of ruminal incubation simulated by in vitro and in situ fermentation. The species studied were butterfly pea, stylosanthes, archer and perennial soybean. Four Holstein dairy cows fistulated in rumen were used in the in situ stage. A completely randomized design was used, in a 4 × 6 factorial arrangement (four species, six treatment periods) in the in vitro stage, with four repetitions. A completely randomized block design, arranged in a 4 × 6 factorial scheme (four species × six incubation periods), was used in the in situ stage, with four repetitions. The seeds (50 units of only one species at each repetition) were placed in erlenmeyer flask (250 mL) and were put in a 10 × 15 cm nylon bag in the in vitro stage. The times of incubation were: 6, 12, 24, 48, 96 and 144 hours and the time zero was estimated in the laboratory. The results demonstrate that, when submitted to ruminal incubation, due to their hard and impermeable teguments, legume seeds presented high resistance potential, and, thus, greater chances of germinating after passage through the gastrointestinal tract of bovines, when defecated in pastures. However, stylosanthes are not recommended for insertion in bovine feeding for this purpose, because they do not resist ruminal digestion.

Inner bark extracts of Stryphnodendron adstringens, a leguminous tree species known as Barbatimão, are often incorporated to phytotherapic formulations due to their antimicrobial and healing activities. In this study, extracts from S. adstringens accessions collected in 12 distinct locations were investigated in order to determine the rates of tannins in inner barks and to validate S. adstringens antibacterial and antifungal effectiveness. Yields of tannins were quantified by colorimetric assay following methodology described in the Brazilian Pharmacopoeia and the antimicrobial activity was determined by microdilution technique proposed by the National Committee for Clinical Laboratory Standards using S. adstringens hydroalcoholic and aqueous extracts and semi-purified fractions. Investigated extracts did not present significant antibacterial activity though aqueous extracts exhibited antifungal effect against both Trichophyton rubrum mutant and clinical strains (MIC 156 μg/mL). A positive correlation between tannin concentration and antifungal activity was observed and the accessions collected in delfinópolis (MG) were considered elite.
