Water quality analysis of Ribeirão São João in the Municiply of Porto Nacional – Tocantins / Análise da qualidade da água do Ribeirão São João no Município de Porto Nacional - Tocantins

Water is the source of life and an indispensable element of nature for human survival. Over the centuries, the available water resources have undergone constant crisis processes, especially when it comes to water pollution that affects its effectiveness for consumption. The monitoring of the water quality offers qualitative information about the water based on the parameters adopted in the CONAMA Resolution nº. 357/2005 and the calculation IQA NSF of the National Sanitation Foundation (APHA, 2005). The study about the water quality index aims to obtain information about the quality of the hydric resource available in Ribeirão São João in Porto Nacional - Tocantins, which has multiple uses such as: public supply, fishing, leisure, among others. The analysis undertaken to verify the quality of the water adopted procedures for analyzing the parameters of temperature, oxygen, pH, total nitrogen, total phosphorus, fecal coliforms, total solids and turbidity that occurred between the months of August and September 2021. The collection and analysis of water samples showed that the Ribeirão presents acceptable levels within the parameters established by the literature studied and infer that the water quality is considered average for the purposes of capitation and human consumption

The importance of the brand for the success of a company/ A importância da marca para o sucesso de uma empresa

The objective of this work was to clarify the importance of using marketing strategies to build a brand that, in turn, will lead the company to success. The theoretical foundation is based on the concepts of marketing, integrated marketing communication, brand and branding. The integrated marketing communication contributes to the strengthening of the brand through branding actions, which allow a better strategic positioning in the market. The methodology of this work consists of a bibliographical study, due to the need to relate these three theoretical elements that, in a structured way, bring countless benefits for all organizations. This study has shown that brand management is an important strategic tool for the success of a company and that its rise depends on the message of trust that it expresses to customers

Ultrastructural and Cytotoxic Effects of Metarhizium robertsii Infection on Rhipicephalus microplus Hemocytes

Metarhizium is an entomopathogenic fungus widely employed in the biological control of arthropods. Hemocytes present in the hemolymph of invertebrates are the cells involved in the immune response of arthropods. Despite this, knowledge about Rhipicephalus microplus hemocytes morphological aspects as well as their role in response to the fungal infection is scarce. The present study aimed to analyze the hemocytes of R. microplus females after Metarhizium robertsii infection, using light and electron microscopy approaches associated with the cytotoxicity evaluation. Five types of hemocytes (prohemocytes, spherulocytes, plasmatocytes, granulocytes, and oenocytoids) were described in the hemolymph of uninfected ticks, while only prohemocytes, granulocytes, and plasmatocytes were observed in fungus-infected tick females. Twenty-four hours after the fungal infection, only granulocytes and plasmatocytes were detected in the transmission electron microscopy analysis. Hemocytes from fungus-infected tick females showed several cytoplasmic vacuoles with different electron densities, and lipid droplets in close contact to low electron density vacuoles, as well as the formation of autophagosomes and subcellular material in different stages of degradation could also be observed. M. robertsii propagules were more toxic to tick hemocytes in the highest concentration tested (1.0 × 108 conidia mL−1). Interestingly, the lowest fungus concentration did not affect significantly the cell viability. Microanalysis showed that cells granules from fungus-infected and uninfected ticks had similar composition. This study addressed the first report of fungal cytotoxicity analyzing ultrastructural effects on hemocytes of R. microplus infected with entomopathogenic fungi. These results open new perspectives for the comprehension of ticks physiology and pathology, allowing the identification of new targets for the biological control

Gerenciamento resíduos gerados na constrção civil: uma revisão bibliográfica / management waste generated in civil construction: a bibliographic review

A construção civil representa uma área de suma importância para o desenvolvimento do país, tanto no que se refere à infraestrutura, quanto para a economia, sendo a segunda maior indústria do país, e com grande representatividade no Produto Interno Bruto, devido à geração de emprego e renda. É um setor que possui grande movimentação e por esse motivo é responsável por uma grande parcela da geração de resíduos, com um percentual entre 20 e 50%. Frente ao exposto, a presente pesquisa objetivou realizar um levantamento de medidas a serem adotadas para um gerenciamento dos resíduos gerados a partir da construção civil. Por meio de uma pesquisa bibliográfica, descritiva e exploratória, identificou-se que a grande parcela dos resíduos gerados pela construção civil se dá por uma ausência ou ineficiência de planejamento e gerenciamento. Uma boa eficiência na gestão dos resíduos da construção civil deve respeitar a redução da geração de resíduos na fonte; reutilização dos mesmos; reciclagem e disposição final adequada. Visando minimizar os impactos causados pela geração de resíduos pela indústria da construção civil, no ano de 2002 foi aprovada a Resolução CONAMA 407/2002, definindo a obrigatoriedade de destinação adequada dos resíduos através de uma segregação dos mesmos por parte do gerador, devendo ser um parâmetro adotado em obras civis de todo o país em busca de uma sustentabilidade na construção civil por todos os agentes envolvidos
