Climatic Variations and Consumption of Urban Water  [PDF]
Amaury de Souza, Flavio Aristone, Ismail Sabbah, Debora A. da Silva Santos, Ana Paola de Souza Lima, Gabriela Lima
Atmospheric and Climate Sciences (ACS) , 2015, DOI: 10.4236/acs.2015.53022
Abstract: This study aims to develop a statistical modelling framework of urban water consumption forecast for the city of Aquidauana, Brazil from year 2005 to 2014, monthly data, using multiple linear regression, cluster analysis, and principal component analysis. These forecasts were based on historical data collected through SANESUL System (Water Systems of South Mato Grosso). The meteorological data were provided by the Water Resources Monitoring Center of South Mato Grosso—CEMTEC. The statistical model developed explains 71.5% of the variance with three factors: number of consumers (19.3%), seasonality (37.8%), and climate regression (14.3%). The model was further validated using an independent set of data from January 2005 to November 2014, with an R2 of 86% and error of 1.7%. The results indicated no intervention of climate variables in the phenomenon. This tool, combined with the perception of the potential and limitations of managers of water resources and public policy makers, can be used in the regulation of per capita consumption, and thereby achieve the optimization of available resources and also contribute to the sustainable perspective of water resources.

Bruno Cardoso Pedrosa, Tuani Cristine Lima de Souza, Ana Paula Dias Turetta, Heitor Luis da Costa Coutinho
Journal of Geographic Information System (JGIS) , 2016, DOI: 10.4236/jgis.2016.82014
Abstract: The current study approaches the sugarcane culture expansion in Southwestern Goiás, especially in Mineiros, Quirinópolis and Rio Verde counties, which represent different times and responses to this process. The current logistics structure and future prospects for sugarcane and its derivatives transportation are studied at national level with emphasis to the aforementioned micro-region. Maps showing land use and land cover in three different years were generated from Landsat TM-5 satellite images and they were used to analyze the dynamics of changes in land use and in land cover. The region is marked by strong and rapid growth in the agricultural sector and its sugar-energy industry has been expanding in recent years, although with different aspects among its counties. Since it is a promising region in this sector, due to the favorable soil and weather conditions to the crop, the region requires more investment and planning in logistics to ensure production flow and to make it stronger within domestic and foreign markets.
Varia??o de curta escala temporal de bactérias, plcofltoplancton e nanoheterótrofos na regi?o de Ubatuba - SP, Brasil

Brazilian Journal of Oceanography , 1996, DOI: 10.1590/S1679-87591996000100005
Abstract: an investigation on the temporal variation of the planktonic microbial community (bacteria, total picophytoplankton and nanoheterotrophs) was undertaken over 7 days period (from february 27 to march 4, 1988) in a coastal region of ubatuba (23°8, 45°w). samples were obtained at the thermocline twice daily (at high and low tides) during daylight time. average density of nanoheterotrophs (nh) was 2.3 x 103 cells m-l, ranging from 0.9 to 3.5 x 10 cells mrl. total picophytoplankton was represfnted mostly by chroococcoid cyanobacteria and varie2 from 1.0 tp 7.6 x 104 cells m-l. bacterial numbers ranged from 1.0 to 2.7 x 106 cells m-l. the oscillation pattern displayed by the bacterial populations was out of phase in relation to chl-a variation. the time interval between chl-a peak and the bacterial one was approximately 24 hours. at the beginning of studied period, the interrelationship between nanoheterotrophs and bacteria-picophytoplankton was characterized bya coupled oscillation, suggesting a predator- prey interaction. during the last three days (marsh 2-4) the densities of three populations have fluctuated in phase. the influences of weather conditions, tidal movements, and predation by microzooplankton and metazoans are discussed. many factors can affect the relationships between nanoheterotrophs and bacterial-picophytoplankton, but the oscillation pattern observed in this report are not fortuitous and may indicate an intense predation activity of nanoheterotrophs on pico-organisms.

Abstract: context and objective: child development is negatively influenced by multiple risk factors associated with poverty, thus indicating the importance of identifying the most vulnerable groups within populations that are apparently homogeneous regarding their state of socioeconomic deprivation. this study aimed to identify different levels of poverty in a population of low socioeconomic condition and to ascertain their influence on infants' neuropsychomotor development. design and setting: cross-sectional study conducted at four family health units in the health district iv in the city of recife, brazil. methods: the sample comprised 136 infants aged 9 to 12 months, which represented 86% of all the infants in this age group, registered at the units studied. socioeconomic status was assessed through a specific index and child development through the bayley iii screening test. results: around 20% of the families were in the lowest quartile of the socioeconomic level index and these presented the highest frequency of infants with suspected delay in receptive communication. maternal and paternal unemployment negatively influenced receptive communication and cognition, respectively. not possessing a cell phone (a reflection of low socioeconomic status) was associated with worse cognitive performance and gross motricity. male infants showed a higher frequency of suspected delay in receptive communication. conclusions: infants of more precarious socioeconomic status more frequently present suspected developmental delay. development monitoring and intervention programs should be encouraged for this subgroup, thereby providing these children with a better chance of becoming productive citizens in the future.

Biotemas , 2011,
Abstract: The crab-eating fox is the most common Canidae of South America. In general, its diet varies according to the season and inhabited region. In this study, the medullary cone of the crab-eating fox was described because of interests in comparative anatomy, with the goal of providing information that could assist in epidural anesthesia, which cannot be efficiently practiced without knowledge of this anatomical region. We investigated an adult male from the Bauxite Mine (Paragominas, PA), which was dissected in the lumbosacral region. The medullary cone was 10.13 cm long; the base began at the L6 and the apex was at the S3. Considering that the specimen studied had nine lumbar and four sacral vertebrae, we conclude that the sacrococcygeal region is probably the most suitable place for epidural anesthesia.
Characteristics of Mesenchymal Stem Cells under Hypoxia  [PDF]
Bruna Amorin, Ana Paula Alegretti, Vanessa de Souza Valim, Annelise Martins Pezzi da Silva, Maria Aparecida Lima da Silva, Felipe Sehn, Lucia Silla
CellBio (CellBio) , 2013, DOI: 10.4236/cellbio.2013.21002
Abstract:

Mesenchymal stem cells (MSC) are considered non-hematopoietic multipotent stem cells with self-renewal properties and the ability to differentiate into a variety of mesenchymal tissues. Optimal conditions for the culture of these cells have been the subject of investigation for several years. In particular, ideal oxygen tension levels have not been established in the literature. In physiological environments, oxygen tension may vary from 12% in peripheral blood to 1% in the deep zone of cartilage regions. In any case, oxygen tension is considerably lower in vivo when compared with the normal atmosphere of standard cell culture conditions (21%). The objective of this study was to review the literature available on MSC characteristics (cell cycle, survival, proliferation, differentiation, morphology, immunophenotype, cytogenetics) when cultured under hypoxic conditions. Our focus on optimal culture conditions is justified by the key role currently played by these cells in regenerative medicine.
