Neurotoxicity evaluation of meloxicam in the alternative in vivo model, Caenorhabditis elegans
No full textInflammatory processes cause changes in the permeability of the blood brain barrier. Non-steroidal anti-inflammatory drugs (NSAID) are most commonly used to treat these inflammatory processes, including meloxicam, and they can reach the central nervous system (CNS) and cause neurotoxicity. Since there are no studies evaluating the neurotoxicity of NSAID in alternative models of toxicity, the aim of this study was to evaluate the acute neurotoxicity (through nematodes changes in behavior) of meloxicam in an alternative in vivo model, Caenorhabditis elegans, as well as, to determine meloxicam toxicity through LD50 and development assessments. Meloxicam LD50 was high (50.03 mg/mL) and only the highest dose (100 mg/mL) caused a decrease in the nematode body size, indicating low toxicity in this alternative model. Besides, a neurological effect was observed only in the highest dose. Meloxicam showed neurotoxicity only at a very high dose, suggesting low potential to cause toxicity in the CNS. However, further studies are necessary to evaluate meloxicam neurotoxicity
Application of solid-liquid extraction with organic acids for recovery of precious metal from technological waste in disuse
No full textThe electro and electronic industry has been increasing gradually, causing an increase in the generation of waste of electrical and electronic equipment, which have several components that have added value such as - for example - gold. Aiming at environmental protection, measures are sought for the recovery of these metals, through tests with several technologies such as leaching. This consists in separating the component from the solid part, transferring it to the liquid part, using acids. It is necessary to study acids that are less harmful to the environment. Thus, microprocessors of obsolete computers were collected, their characterization was carried out and the elements present in the pins were identified. After the characterization, the leaching stage was carried out, firstly with aqua regia; then with acetic and citric acids. The leaching results presented about 10 mg / L of gold with aqua regia and about 0.5 mg / L with citric acid
The Animal production and economic viability of integrated crop livestock systems
No full textIntegrated crop-livestock-forest system appears as strategy to reduce pasture recovery costs and diversify farmer’s income with the sale of the wood of eucalyptus trees. The objective of this work was to evaluate the animal performance and economic viability of systems without shade availability (ICL: Integrated Crop-Livestock) and with two tree densities (ICLF-1L: Integrated Crop-Livestock-Forest, 196 trees ha-1; ICLF-3L: Integrated Crop-Livestock-Forest, 448 trees ha-1). Sixty castrated Nellore cattle were used to evaluate performance during rearing and finishing. For economic analysis, the cash receipts, cash outflow, cash flow, net cash flow and internal rate of return (IRR) were evaluated between December 2012 and June 2016. The performance of the animals was lower in ICLF-3L system (P<0.05) due to the higher density of trees, and consequently, greater shading of the pasture. In ICL and ICLF-1L systems, the revenue from soybean and corn fully paid for the costs of implementing the systems, and ICLF-1L still covered the cost of forest deployment. In ICLF-3L, the costs were almost completely covered. The reduction in the productive indices also reduced the revenue from the slaughter of cattle in ICLF-3L, with the highest revenue in ICL and ICLF-1L, respectively. In addition, the IRR in ICL and ICLF-1L was higher. ICLFs contribute to the amortization of the recovery costs of the pastures and the implantation of eucalyptus. The ICL and ICLF-1L is more economically viable tham ICFL-3L until the fourth year of implementation
Measuring Brazilian Inequality Using the Gender Inequality Index
No full textGender inequality is a common feature shared by all countries, in different degrees. Its importance is evident in the United Nations 2030 Agenda. The Sustainable Development Goal (SDG) number 5 is mainly dedicated to it. However, for its multidimensional features, different SDGs include it among their targets, the third (health), fourth (education), and tenth (labor) goals in particular. A composite index better describes multiple disparities. In this paper, the Gender Inequality Index (GII), presented in the 2010 Human Development Report, is discussed and then calculated for the Brazilian Federation Units. Its dimensions, health, empowerment, and economic activity cover three crucial dimensions of gender inequality. The GII contributes to evaluate how inequality lowers human development among countries and within a country, as presented in this study. Even though its complex methodology, it is an important tool for policy guidance
Environmental Aspects of Production Management of Services in The Amazon
No full textEnvironmental degradation is one of the most discussed topics today, but organizations also consider it a source of competitive advantage. This study is qualitative and uses the Case Study Method. Data were collected in a pest control company located in Porto Velho, Rondônia, Brazil. As its main topic, it takes aspects of environmental management in a pest control company´s production process in the city of Porto Velho. Its specific goals are to (1) identify which tools and sustainable production methods are used by the company in its production process; (2) highlight the competitive advantages arising from the incorporation of aspects of environmental management in production processes; and (3) indicate the innovation process that best contributes to the improvement of the company´s environmental management. Assessing the environmental aspects of the company´s production management revealed satisfactory results. The company is engaged in sustainable development and is gradually pursuing improvements to its methods of maintaining and conserving the environment. The subsidies mentioned allow the degree of sustainability demanded by contemporary society, which benefits from the environmental services offered. This study is a university´s research contribution to managers and stakeholders who want to learn more about the applicability of concepts of an environmental management system in pest control companie
Application of indexes to evaluate the water quality of the Continguiba/Pindoba Irrigated Perimeter in Sergipe, Brazil
No full textIrrigation makes food production viable, but the quality and quantity of water may be compromised as a result of inadequate management, which may lead to an increase in the concentration of nutrients, heavy metals and agrochemicals. This study aimed to characterize and monitor the water quality of the Continguiba/Pindoba Irrigated Perimeter in Sergipe, Brazil. Secondary data from the Water Quality Monitoring Program were used through the reports of monitoring campaigns carried out between 2013 and 2014. The Water Quality Index (WQI) and the Trophic State Index (TSI) were used in the water quality assessment. The results showed that there is an influence of seasonality, where the best indices were obtained in the rainy season, with the WQI characterized as regular to good, and the TSI characterized as oligotrophic. There was interference from the drainage of rice lots in the dry season, contributing to the increase of nutrients. There was no spatial influence for WQI, which may be related to the eclipse effect, which attenuated the negative impact of a certain variable given the aggregation of several variables. The TSI suffered spatial influence, the waters added to agricultural and fish lots were classified as oligotrophic or ultraoligotrophic, already in the drainage were found indexes of super-utrophic state
A Mobile application proposal for mapping of multi-drug resistant bacteria information management:: A study applied in a Brazilian city
No full textThe mapping and identification of multi-drug resistant (MDR) bacteria in affluents and effluents requires updated data on their reality and context. However, the process of analyzing these results is still slow and sometimes ineffective due to the lack of adequate technological mechanisms. This article presents the development of a mobile application as a tool for the information management system using geolocation and dashboads to map collection points, as well as resources to analyze the results obtained. The M.I.T. APP Inventor was used in the project along with PHP PDO and MySQL technology in the web server layer. The preliminary results indicated an interesting alternative solution to the specialists' requirements to contribute to management and decision-making, as well as a useful tool for interested health agents
Native Languages in Post Independent Algeria: The Case of Berber
No full textThe present paper purports to shed light on the sociolinguistic picture of Berber in Algeria through providing both a descriptive and critical analysis as far as language diversity and mother tongues are concerned. An attempt has been also made to echo the case of Berber as a native language and its potential at the ethno- cultural level. With the aim of evaluating the situation of Berber, we promptly address the following questions: (i) Can diversity be regarded as a cultural richness? (ii) To what extent can Berber be able to generate positive attitudes towards learning it? (iii) What are the implications of its corpus planning

The conclusive differential analysis of the comparative level between experimental and control group, corresponding to 6 subdimensions of SIS, carried out through t-test for 2 independent samples, it´s concluded the comparative data are significantly different between both groups: experimental and control group, which allows deducing the specificity of this Scale like complementary diagnosis adapted to people with ASD
How to reduce food waste in the B_M company`s restaurant
No full textAbout a third of all food produced in the world is wasted. To reduce this unfortunate number, several companies are trying to do their part. The article analyzes the causes of food waste in the B_M company restaurant, located in the Industrial Pole of Manaus, to propose actions to improve its environmental performance. The research is of an applied nature, with data collection and analysis using qualitative and quantitative approaches. The procedures involve case study, documentary and bibliographic research, and survey application, based on a questionnaire composed of 2 sections and nine questions, applied randomly at lunchtime with 300 employees. After analyzing the data, it was concluded that waste is related to the preparation and menu of meals, occurring effectively in the consumption phase, when 58% of respondents leave food scraps on the plate, due to the bad taste of the meals (81 %), not pleasant menu (41%) and for over-serving (25%). The main foods left on the plate are beef (34%), chicken meat (32%), rice (23%), beans (20%), and fish (20%). In the end, six suggestions were given to managers to reduce food waste at the restaurant
