RESUMO:A implantação de atividades florestais, agrícolas e pecuária vem modificando a cobertura vegetal original grande parte do território brasileiro.Ecossistemas naturais, como o cerrado floresta amazônica, vêm perdendo suas características originais cedendo lugar para essas atividades.O objetivo foi avaliar os atributos solo sob diferentes usos na fazenda Santa Rita, em Humaitá
Ansiedade, síndrome do pânico, depressão e burnout são diagnósticos recorrentes podem ser agravados nos profissionais da saúde. Episódios considerados adversos nesses espaços têm potencial de virar gatilhos mentais negativos. A atividade laboral faz parte vida das pessoas pode estar relacionada a sentimentos prazer e/ou sofrimento. Dissertar sobre prevalência uso psicofármacos entre saúde no ambiente trabalho. O presente trabalho é uma revisão integrativa literatura. pesquisa foi realizada...
ABSTRACT Heavy metals are naturally found in soils, but their levels may increase as a result of anthropogenic actions. This study aimed at determining the concentrations Cd, Cu, Mn, Ni, Pb and Zn Yellow Latosol from vegetable crops areas, well influence cultivation position landscape on accumulation these elements. Soil samples were collected five farming areas four with natural vegetation, which served reference. was along planting rows three transect positions (upper, middle lower...
ABSTRACT Model calibration is a fundamental factor to obtain high accuracy in the estimation of crop growth and yield. This study aimed parameterize genetic ecotype coefficients DSSAT/Canegro model for five sugarcane cultivars kept under three water managements, besides evaluating predicting stalk yield, sugar yield height. Experimental field data were obtained from two years (2016 2017) cultivation at FCAV/Universidade Estadual Paulista, Jaboticabal, SP, Brazil. The maintained supplementary...
The field study of B and Zn on Gladiolus was conducted at Floriculture Farm HRC, Gazipur RARS, Jessore during 2005-2006. objective to evaluate the response find out optimum dose same for production gladiolus. It appeared in studied data reveals that made promising growth floral characters also noticed tables both either single or combination exerted tremendous effect yield quality However, with subsequent addition higher rates progressively increased selective flower some extent beyond...
Indian Black Earths (IBEs) are distributed throughout the Amazon.They characterized by their high chemical fertility and agricultural potential.IBEs have organic carbon, favouring improvement of soil structure.This work aimed to evaluate aggregates carbon (OC) spatial variability in different IBEs southern Amazonas.We evaluated variability, mean weight diameter (MWD), bulk density (ρ b ) aggregate classes under three uses soil: pasture, cocoa, coffee.We collected 528 samples a point grid...
The consumption of contaminated water is a major source heavy metal contamination in humans and animals. This study therefore aimed to assess Cd, Cu, Mn, Ni, Pb, Zn levels used for human animal vegetable crop irrigation Camocim de São Félix, Pernambuco, Brazil. Water samples were collected on the studied farms from an artesian well reservoirs as irrigation. results showed that concentrations Cd (> 0.001 mg L-1), Ni 0.025 L-1) Pb 0.01 above maximum allowable limits established under...
With agricultural expansion in Amazonian regions, studies are needed to verify the effect of mechanization on soils regions. This study aimed assess soil physical attributes under different compaction conditions induced by tractor traffic a southern Amazonas State, Brazil. Treatments consisted three levels: conventional tillage without additional (CT) and with four (CTc4) eight passes (CTc8). An intense increase aggregate diameter was observed superficial layer (0.00-0.05 m) from passes,...
The content and availability of heavy metals in intensively cultivated soils are important issues because these potential environmental contaminants toxic to living beings.Thus, the aim this study was evaluate levels Cd, Mn, Cu, Pb, Ni Zn available soil five agricultural areas compared adjacent native forests, determine risk soil, water plant contamination.A total 180 samples were collected at two depths (0.00 -0.10 0.10 -0.30 m), edible extracted from plants soils.Water taken reservoirs...
The concept of production environments, which is widely used to classify the yield potential soils, and magnetic susceptibility (MS), emerging as an important tool for mapping ultra-detailed areas. Given this background, paper aims evaluate use MS a identification areas with different enhancing sugarcane quality, allocation varieties. An area 445 ha was sampled at 1 point every 7 ha, 14 points were determined stratified sampling following top landscape. Particle size samples depths 0.0-0.2...
The low natural fertility of tropical soils and the mineralogy almost dominated by iron aluminum oxides limit availability phosphorus (P) to plants, causing negative impacts on soybean yield. Objective was evaluate effect phosphate fertilization with different maximum adsorption capacities (PAC) in development. experiment carried out under greenhouse conditions, using Red-yellow Latosol (RYL) a Typic Hapludalf (TH) soil as substrate. analyses were performed completely randomized experimental...
Abstract. Spatial mapping of soil chemical attributes is essential for sampling efficiency and agricultural planning management, ensuring a regional development sustainability the unique characteristics archaeological black earths (ABEs). Thus, this study was developed aiming at assessing spatial variability density in soils ABEs under pasture southern Amazonas, Brazil. A grid 56 × 80 m with regular spacings 8 installed experimental area samples were taken from crossing points depths...
Studying particle size distribution is important to understand soil structure and formation processes. This research aimed assess the fractal dimension of texture in Indian Dark Earth (IDE) areas southern Amazonas state under different land uses, as follows: two municipality Apuí, one growing cocoa other coffee; a grassland area Manicoré; forest Novo Aripuanã. A sampling grid containing 88 collection points (intersecting on grid) was established each area, measuring 80 x 42 m for...
Para se obter uma producao satisfatoria e necessario alem de um bom manejo, fazer a escolha das cultivares que melhor adequam determinada regiao. Nesse sentido, o objetivo deste trabalho foi avaliar sorgo sacarino (Sorghum bicolor (L.) Moench) na regiao Humaita, AM. O delineamento experimental em blocos ao acaso, compostos por treze quatro repeticoes. Cada parcela composta cinco linhas 5 m comprimento, com espacamentos regulares 0,70 nas entre linhas. Foram avaliadas as seguintes variaveis:...
Abstract Egypt, as the host for previous UN COP27 in 2022, has committed to emissions reductions support of limiting global warming. Carbon capture and storage (CCS) offers potential significantly reduce point source CO2 country. Accordingly, Egyptian operator BAPETCO, along with partners Cheiron Capricorn, is exploring carbon sequester more than 350,000 metric tons per annum.at two fields Egypt’s Western Desert. Storage candidates comprise 20 stacked geological formations starting from...
Abstract Conventional subsurface reservoir candidates for CO2 Sequestration are usually just deeper than 800 m to ensure is injected at supercritical state, typically these shallow, gently dipped, low pressure saline aquifer or completely depleted and abandoned hydrocarbon reservoirs. However, in this study within the western desert of Egypt, none reservoirs aquifers below too tight with no injectivity. So, only way was target ultra deep 3 km virgin more 5000 psi. These highly titled,...
O conhecimento da qualidade física do solo em sistemas agroflorestais na região amazônica é importante para conhecer o nível de mudança no ecossistema e subsidiar escolha metodologias manejo conservacionista. objetivo deste trabalho foi avaliar a variabilidade espacial função conversão floresta sistema agroflorestal Amazônia Central. estudo realizado uma propriedade rural com cultivo agrofloresta (SAF) área sob nativa (FN), localizado município Silves, Amazonas.

Abstract In this case study we present a best practice for site screening & optimizing safe CO2 sequestration through simulation in challenging ultra deep saline aquifers at depth ranging from 3 to 4 Km within the western desert of Egypt. General, storage sites are typically just deeper than 800 m make sure that is supercritical state, these depleted reservoirs or shallow with gentle formation dipping and moderate salinity, However screened zones characterized by high dip angles more...
