TECHNICAL AND ECONOMICAL FEASIBILITY ANALYSIS APPLIED TO HEALTH:: SCHOOL-CLINIC IMPLANTATION PROJECT
The importance of the school-clinic to psychology course is associated to teaching, researching and extension affairs in public universities in Brazil. Considering the actual context in Santo Antônio city, Bahia, in which is located the psychology course (Centro de Ciências da Saúde - Health Sciences Center - UFRB), it´s possible to realize that the institutions that actually assist mental health don´t have the necessary basic structure to the course´s academic needs. These limitations can make the clinical formation harder, restricting probation vacancies. The objective of the present study is to demonstrate the processes of economic and technical viability analysis applied in health. The used methodology was the study of economic and technical feasibility. The analysis object was the project of construction of a psychology school-clinic construction in the Universidad Federal do Recôncavo da Bahia (UFRB). These results can contribute to increase other feasibility studies of the health care area. The economy instruments usage for health care can reduce the failure of many public and private enterprises.

Interferência do manejo intercalar de leguminosas perenes nas características vegetativas e produtivas do cafeeiro
Intercropped legumes in coffee rows are nutrients sources, providing soil coverage, reducing weed infestation, however, they can negative interfere on coffee. This study evaluated interference of forage peanuts and perennial soybean on growth and yield of coffee plants. The experiment was carried out in Patrocínio/MG, in a 11 years old producing coffee orchard, cultivar Catuaí Vermelho IAC-99, spaced by 3,80 x 0,70 m. Nine treatments were evaluated as a 23+1 factorial, in randomized blocks, with 4 replicates, with two perennial legumes: forage peanuts (Arachis pintoi) and perennial soybean (Neonotonia wightii); two types of side management: without side management, or with side management with glyphosate at 50 cm from canopy projection; two types of vertical management: no vertical management, or with vertical management at 5 cm above soil level. The additional treatment, the control, was done with the herbicide glyphosate (1.0 kg ha-1 of acid equivalent) in the whole plot (row). Perennial soybean, regardless of management, reduced the average number of nodes and coffee yield. Legume growth with no side management also affected coffee yield negatively, with greater interference during the high yield year. Forage peanut, with side management, did not affect the vegetative and yield characteristics of coffee.As leguminosas intercaladas nas entrelinhas do cafezal fazem adubação verde, proporcionam uma boa cobertura do solo e diminuem a infestação de plantas daninhas, porém, podem competir com o cafeeiro. O objetivo desse estudo foi avaliar a interferência do manejo do amendoim-forrageiro e da soja-perene nas características vegetativas e produtivas do cafeeiro. O experimento foi instalado no município de Patrocínio/MG, em uma lavoura de café em produção da cultivar Catuaí Vermelho, linhagem IAC-99, no espaçamento de 3,80 x 0,70 m com 11 anos de idade. Num esquema fatorial 23+1, no delineamento em blocos casualizados com 4 repetições, foram instalados nove tratamentos, sendo duas espécies de leguminosas perenes: amendoim-forrageiro (Arachis pintoi) e soja-perene (Glycine wightii); dois tipos de manejo lateral: sem manejo lateral e com manejo lateral com glyphosate a 50 cm da projeção da saia; dois tipos de manejo vertical: sem manejo vertical e com manejo vertical de poda das leguminosas a 5 cm do solo. O tratamento adicional, correspondente à testemunha, consistiu da aplicação do herbicida glyphosate (1,0 kg ha-1 de equivalente ácido) nas entrelinhas da parcela. A soja-perene, independente do manejo, diminui o número médio de nós e a produtividade de café. O cultivo de leguminosas sem o manejo lateral também prejudica a produtividade de café, sendo a interferência maior no ano de carga alta. O amendoim-forrageiro, manejado lateralmente, não causa interferência nas características vegetativas e produtivas do cafeeiro
INFLUÊNCIA DO ESTRESSE SALINO SOBRE A EMERGÊNCIA E DESENVOLVIMENTO INICIAL DO PINHÃO MANSO
O presente trabalho teve o objetivo de avaliar a influência do estresse salino sobre a emergência e desenvolvimento inicial do pinhão manso (Jatropha curcas L.). Os tratamentos constaram de dois sais (NaCl e KCl) e seis concentrações (0; 2,0; 4,0; 6,0; 8,0 e 10 dS.m-1) distribuídos em quatro repetições de 50 sementes, num delineamento experimental inteiramente casualizado (DIC) em arranjo fatorial 2x6. As variáveis analisadas foram compostas pela porcentagem de emergência (EMERG), índice de velocidade de emergência (IVE), tempo médio de emergência (TME), comprimento da parte aérea (CPA), comprimento de raiz (CR), peso seco da parte aérea (PSPA) e peso seco da raiz (PSR). As maiores concentrações com 8 e 10 dS.m-1 de KCl causaram efeito negativo sobre a emergência do pinhão manso. Independente dos sais, o aumento da concentração promoveu redução crescente dos comprimentos da parte aérea e da raiz do pinhão manso. O incremento das concentrações de NaCl e KCl causaram decréscimo da matéria seca da parte aérea e da raiz, com o KCl causando maior redução. O estresse salino provocou no pinhão manso maior diminuição do crescimento e da matéria seca da parte aérea do que da raiz.  
Boosting big data streaming applications in clouds with burstFlow
The rapid growth of stream applications in financial markets, health care, education, social media, and sensor networks represents a remarkable milestone for data processing and analytic in recent years, leading to new challenges to handle Big Data in real-time. Traditionally, a single cloud infrastructure often holds the deployment of Stream Processing applications because it has extensive and adaptative virtual computing resources. Hence, data sources send data from distant and different locations of the cloud infrastructure, increasing the application latency. The cloud infrastructure may be geographically distributed and it requires to run a set of frameworks to handle communication. These frameworks often comprise a Message Queue System and a Stream Processing Framework. The frameworks explore Multi-Cloud deploying each service in a different cloud and communication via high latency network links. This creates challenges to meet real-time application requirements because the data streams have different and unpredictable latencies forcing cloud providers' communication systems to adjust to the environment changes continually. Previous works explore static micro-batch demonstrating its potential to overcome communication issues. This paper introduces BurstFlow, a tool for enhancing communication across data sources located at the edges of the Internet and Big Data Stream Processing applications located in cloud infrastructures. BurstFlow introduces a strategy for adjusting the micro-batch sizes dynamically according to the time required for communication and computation. BurstFlow also presents an adaptive data partition policy for distributing incoming streams across available machines by considering memory and CPU capacities. The experiments use a real-world multi-cloud deployment showing that BurstFlow can reduce the execution time up to 77% when compared to the state-of-the-art solutions, improving CPU efficiency by up to 49%
Qualidade da carne e desempenho de suínos alimentados com dietas contendo farinha de silagem de pescado
The objective of this work was to determine the nutrient digestibility and metabolizable energy (ME) of fish silage, as well as to evaluate the effect of the dietary inclusion of fish silage meal (FSM) in diets on the performance, carcass characteristics, meat quality, sensory analysis of meat and mortadella, and economic viability of growing and finishing pigs. In the digestibility assay, 16 barrows (33.20±4.93 kg) received diets with and without FSM. The fish silage had 39.01% crude protein and 4,032 kcal kg-1 ME. In the performance assay, 32 barrows (26.00±1.68 kg) were fed diets containing different inclusion levels of FSM (0, 25, 50, and 75%). FSM, obtained from the mixture (1:1) of fish silage with corn, showed a quadratic effect on average daily gain, and the best result was obtained with the inclusion level of 25.83%. The results for feed conversion and economic viability indicate that up to 25% FSM, corresponding to 5.87% of fish silage based on dry matter, can be used in the pig growing and finishing phases.O objetivo deste trabalho foi determinar a digestibilidade de nutrientes e a energia metabolizável (EM) da silagem de pescado, bem como avaliar o efeito da inclusão de farinha de silagem de pescado (FSP) nas dietas sobre o desempenho, as características de carcaça, a qualidade da carne, a análise sensorial da carne e da mortadela, e a viabilidade econômica de suínos em crescimento e terminação. No ensaio de digestibilidade, 16 suínos machos castrados (33,20±4,93 kg) receberam dietas com e sem FSP. A silagem de pescado apresentou 39,01% de proteína bruta e 4.032 kcal kg-1 de EM. No ensaio de desempenho, 32 suínos machos castrados (26,00±1,68 kg) foram alimentados com rações contendo diferentes níveis de inclusão de FSP (0, 25, 50 e 75%). A FSP, obtida a partir da mistura (1:1) da silagem de pescado com milho, apresentou efeito quadrático sobre o ganho diário de peso, e o melhor resultado foi obtido com a inclusão de 25,83%. Os resultados de conversão alimentar e da viabilidade econômica indicam que até 25% de FSP, que corresponde a 5,87% de silagem com base na matéria seca, pode ser utilizada nas fases de crescimento e terminação de suínos

Molecular characterization of occult hepatitis B virus infection in patients with end-stage liver disease in Colombia.
ABSTARCT: Hepatitis B virus (HBV) occult infection (OBI) is a risk factor to be taken into account in transfusion, hemodialysis and organ transplantation. The aim of this study was to identify and characterize at the molecular level OBI cases in patients with end-stage liver disease.
METHODS:
Sixty-six liver samples were obtained from patients with diagnosis of end-stage liver disease submitted to liver transplantation in Medellin (North West, Colombia). Samples obtained from patients who were negative for the surface antigen of HBV (n = 50) were tested for viral DNA detection by nested PCR for ORFs S, C, and X and confirmed by Southern-Blot. OBI cases were analyzed by sequencing the viral genome to determine the genotype and mutations; additionally, viral genome integration events were examined by the Alu-PCR technique.
RESULTS:
In five cases out of 50 patients (10%) the criteria for OBI was confirmed. HBV genotype F (subgenotypes F1 and F3), genotype A and genotype D were characterized in liver samples. Three integration events in chromosomes 5q14.1, 16p13 and 20q12 affecting Receptor-type tyrosine-protein phosphatase T, Ras Protein Specific Guanine Nucleotide Releasing Factor 2, and the zinc finger 263 genes were identified in two OBI cases. Sequence analysis of the viral genome of the 5 OBI cases showed several punctual missense and nonsense mutations affecting ORFs S, P, Core and X.
CONCLUSIONS:
This is the first characterization of OBI in patients with end-stage liver disease in Colombia. The OBI cases were identified in patients with HCV infection or cryptogenic cirrhosis. The integration events (5q14.1, 16p13 and 20q12) described in this study have not been previously reported. Further studies are required to validate the role of mutations and integration events in OBI pathogenesis
Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
