Comparative analysis of sustainability assessment methods in agroecosystems
No full textThe aim of this work was to compare and analyze three different methods of the sustainability evaluation in agricultural systems, such as the Indicateurs de Durabilité des Exploitations Agricoles (IDEA), the weighted Assessment of environmental impact of New Rural activities (APOIA Novo-Rural), and the indicators of sustainability in Agroecosystem (ISA). Those methods were comparied by two criteria. The first one relates to the distribution of sustainability indicators into categories (Endogenous System Operation, Endogenous Resources, Exogenous Systems Operation, and Exogenous Resources) and elements (technical, socioeconomic, natural and cultural resources). The second one involves the conceptual approaches of each method towards the concept of sustainability, objective and target audience, adoption of the systemic approach, level of stakeholder’s participation, level of adequacy, and method flexibility in different realities. The indicators set of each method, although quantitatively different, consider the diversity of elements that involve the agricultural systems. The IDEA method concentrates its indicators on the Endogenous System Operation category, while the APOIA Novo-Rural and the ISA methods concentrate their indicators on the Endogenous Resources category. The IDEA method directs the assessment to the awareness of the environmental processes that surround the agricultural activity in the property. On the other hand, in the APOIA Novo-Rural and the ISA methods, the reflective practice is fostered from impacts on the environment, and can be improved by extension actions. The main difference presented among those methods is the integrative evaluation of the indicators as well as trade-offs involved
Determinate of diarrhea among under-five children in Northwest Ethiopia
No full textThis study aimed to assess the determinants of diarrhea among children under-five in Jabitehnan district, Northwest Ethiopia. A community-based cross-sectional study was done using a cluster sampling technique. The study was done in the Jabitehnan district from April to July 2019. The study was done among women who had children under five during the survey who settled in Jabitehnan district. The main outcome measure was the occurrence of diarrhea. A binary logistic regression was used to identify factors associated with diarrhea. The prevalence of diarrhea was found to be 19.8%. The child lived with whose non-biological mothers were 32.44 times more likely to be exposed to diarrhea compared to the child who lived with whose biological mothers. The odds of being diarrheal for a child whose mother does not wash her hand after latrine was 7.91 times higher than its counterpart. A child whose mother pregnant was 5.66 times higher risk of developing diarrhea than whose mother do not pregnant. The likelihood of diarrhea for children drinking unprotected water were14.1times higher than its counterpart. The magnitude of reported diarrhea was high. Child age, residence, drinking water, pregnant mother, toilet facility, washing hand after latrine, and child live with whom were the main determinates of diarrhea. Addressing these factors will help to prevent future morbidity and mortality of children and will assist in alleviating hygiene and refining their quality of life. Moreover, a trend-based sampling design might be considered for a better understanding
Anatomical characteristics of the accessory hepatic lobe and its clinical-functional particularities
No full textRiedel's lobe (ectopic lobe), also known as the accessory hepatic lobe, consists of an anatomical variation characterized by a tongue-shaped protrusion on the visceral surface of the liver right lobe, fixed by a pedicle. This variant draws attention in the clinical practice, as it can be mistaken for a tumor due to its elongated aspect. The aim of this research was to conduct a study on the anatomical characteristics and clinical and functional peculiarities of the accessory hepatic lobe. The paper is based on a integrative review and observational study on a cadaveric specimen. A cadaver with anatomical variation was used. Data were collected in PubMed, Scielo, and VHL. 257 articles were found in the databases, but only 13 were used for research. In careful review, two rare cases of the accessory lobe in the left lobe of the liver, hypoplastic left lobes, and agenesis of the right hepatic lobe, and often the clinical picture without changes in signs and symptoms were found. These morphological abnormalities' clinical impact is limited in the absence of underlying liver disease, cirrhosis, or known cancer. In case of complications or after the diagnosis of pedunculated tumors in the liver, laparoscopy is well indicated for removing these lobes or tumors

Safety profile, antimicrobial and antibiofilm activities of a nanostructured lipid carrier containing oil and butter from Astrocaryum vulgare: in vitro studies
No full textEthnopharmacological relevance: Tucumã (Astrocaryum vulgare)is a fruit native to the Amazon region. Extracts from the peel and pulp are thought of as promising treatments for bacterial infections. The primary constituents of Tucumã oil and butter possess unsaturated carbon chains that are susceptible to oxidation by light or heat. The oils have high volatility and low aqueous solubility that limits their use without a vehicle. Nanotechnology refers to techniques to solve these problems. Nanostructured lipid carriers (NLC), for example, protect fixed oils degradation by heat or light, as well as from oxidation and evaporation, ensuring greater stability and function, thereby prolonging the useful life of the final product. Study objectives: The objective of this study was to evaluate the hemolytic, cytotoxic, antimicrobial and antibiofilm properties of an NLC containing Tucumã butter and oil soasto improve the solubility and photosensitivity of the compounds, generating better pharmacological efficacy. Materials and methods: The NLC was assessed for stability for 60 days. The cytotoxicity of nanoparticles in peripheral blood mononucleated cells was determined in culture using assays for cell viability, DNA damage, oxidative metabolism and damage to human erythrocytes. Antimicrobial activity was determined using the broth microdilution technique and antibiofilm activity according to standardized protocols. Results: The Tucumã NLC remained stable throughout the evaluated period, with pH between 5.22–5.35, monodisperse distribution (PDI<0.3) and average particle size of 170.7 ± 3nm. Cytotoxicity studies revealed that the NLC is safe and modulates inflammatory processes, demonstrated by increased cell viability and nitric oxide levels. There was low hemolytic activity of the NLC against human erythrocytes almost concentrations tested. Conclusion: Taken together, the data suggest that NLC containing Tucumã oil and butter showed antimicrobial and antibiofilm activity against organisms that cause morbidity and mortality in humans. They may be alternative solutions to public health problems related to bacterial infections

Nonlinear models. An approach to model irrigated and non-irrigated common bean (Phaseolus vulgaris L.) growth
No full textCommon beans reduce their development and productivity when facing soil water deficit. Comprehension about growth response under this condition can be a tool for cultivar selection and escape from scarcity periods. Therefore, the objective was to characterize bean growth in different water conditions using logistic and chanter models. Two experiments (crop season= EI and fallow season = EII) were carried out in Santa Maria, RS, Brazil in a bifactorial scheme (cultivars: Triunfo, Garapiá, FC104; water condition: irrigated, not irrigated) in a completely randomized design. Fortnightly evaluations of height, number of nodes, stem diameter, root length, aerial part, roots, and nodules dry matter were carried out. The data were adjusted according to the accumulated thermal sum by the logistic and chanter models. From the results, it is noted that there was a dissimilar performance between water conditions, cultivars, and experiments. The best adjustment occurred for stem diameter, node number, and aerial part dry matter. Between models, the logistic is the most suitable to describe common bean growth
The Brazilian Economy in the 1980s: The Lost Decade or wins? The consequences of the external debt crisis, inflation and the state crisis
No full textKnown as a lost decade, the 1980s marked several events in Brazil and other Latin American countries. Such events had a profound impact not only on the economy but also on Brazilian democracy. The Brazilian economy in the 1980s went through one of the most serious crises in its history, which resulted in the stagnation of gross domestic product and unprecedented inflation rates. Despite this critical economic situation, social indicators showed positive evolution. It was shown that, although Brazilian families adopted as a strategy to face this crisis the overuse of family work force in the labor market, the evolution of income and poverty in this period was unfavorable
Analysis of Environmental Impacts Caused by the Construction of Power Transmission Lines in Brazil
No full textA country's energy production, transmission and distribution systems are directly linked to its technological advances and economic growth. In Brazil, the creation and expansion of several transmission lines are planned. Such ventures often come up against environmental aspects, as they advance over forest and conservation areas. In this context, the objective of this research was to study the main environmental impacts caused by the implementation of transmission lines in forest areas in order to have a better understanding of the subject, thus being able to minimize or extinguish them. After gathering information, it was found that most of the environmental impacts are due to the deforested area around the transmission lines, called the right of way, which creates a corridor that alters the vegetation. Other serious impacts are related to the type of foundation most used: the micropile, which uses a toxic stabilizing mud in its drilling. The results of this research can be used as a basis to minimize such impacts that can cause damage to the environment and delays in the construction of the lines
TRANSMUTED EXPLORATION IN EFFECTIVE DEVELOPMENT FOR THE AMAZON
No full textThe present article presents historical information about the periods of exploitation, transmuted in the figure of a fallacious development, which in the last 300 years, has not brought effective gains to the population residing in the Amazon. The criticism is based on the historiography of events that took place since Portuguese explorations with hinterland drugs in the 17th and 18th centuries; going through the economic cycle of rubber and mining of minerals; the exploitation of wood from the migratory flow encouraged by the military governments; reaching the present day with the production of agricultural commodities and hydroelectric enterprises. The false developmentalist conceptions make use of the extent to which the Amazon was exploited in the name of false development, said by those who exploit it in the name of progress and not as the effective and sustainable development of those who reside in the Amazon. All of this has resulted in gains for the few, resulting in the social, economic and environmental imbalance of many
