Published: June 2019

Background/Objective: Implementation of the Affordable Care Act (ACA) in the US has given opportunity to obtain health insurance for thousands who were previously uninsured. Many believe that the ACA is an improvement over previous insurance, while others view it as making health care more costly. The purpose of this study was to survey individuals regarding knowledge and perceptions of the ACA.Methods: Researchers in public health, physician assistant studies, pharmacy and medical education developed a survey to assess the impact of the ACA. The survey included demographic questions and statements which assessed ACA support, and perspectives of the ACA’s impact on pharmaceutical and medical coverage and personal out of pocket costs. A convenience sampling was used to recruit participants at a public venue in an urban setting.Results: Demographics of the 179 surveyed include: median age 31 years; 84% Caucasian; 37% married; 58% completed a minimum of four years of college; and 45% with income exceeding $50,000. 13 (7%) were uninsured before the ACA, and 8 (4%) after. 130 (73%) had prescription coverage before the ACA with 107 (60%) reported no change in coverage, 22 (12%) better coverage, and 21 (12%) less coverage after the ACA. An association for ACA support was found based on political affiliation with more Democrats than Republicans supporting the ACA (p < .001). 71 (71%) who support the ACA, reported insurance did not improved after the ACA.Conclusions: These findings identify that in a sample of upper middle class individuals, a majority support the ACA despite a lack of improvement in their own insurance indicating that personal sacrifice for the general population is occurring.

Dimorphandra gardneriana Tul. is a legume, the fruits of which are used in routine extraction by the pharmaceutical industry. The objective was to study the morphological aspects of seeds, germination, seedlings, and young plants of Dimorphandra gardneriana Tul. The study was conducted at the Laboratory of Seed Analysis (LAS), Center of Agricultural Sciences, Federal University of Paraíba (CCA-UFPB), Areia - PB. The external morphological characteristics observed of the seeds were color, texture, and consistency of the teguments; seed shape; hilum and micropyle position; color and thickness of raphe and other structures present; besides internal embryo characteristics (cotyledons, hypocotyl-radicle axis, plumule, and central cylinder); and presence of the endosperm. The seed imbibition curve was determined by the weight of the seeds over a period of 90 h, evaluated every 6 h, with germination being considered as the protrusion of the primary root, or the moment when the primary root breaks the integument, and normal seedlings were evaluated on the 5th day after sowing. Most of the morphological characteristics identified in the plants and seedlings of D. gardneriana resembled those observed for other species of the same genus. The seeds of D. gardneriana Tul., were medium sized, with an average length of 11.95 mm, width of 5.33 mm, and thickness of 4.3 mm, unitegmic with a hard tegument, and impermeable to water. The process of imbibition of the seeds was initially slow and the three-phase curve of imbibition was not clear. The germination was epigeic and phanerocotiledonar and began on the 5th day after sowing.

Given the scarcity of water resources in semi-arid regions and the potential of water reuse as a strategy to solve this problem, this study aimed to evaluate the effects of domestic sewage effluent on growth, yield, and quality of two crisp lettuce cultivars. The research was carried out in greenhouse conditions utilizing an experimental design with randomized blocks in a 5 x 2 factorial scheme, with five concentrations from treated domestic effluent blended with tap water (0, 25, 50, 75 and 100% of treated domestic effluent) and two crisp loose lettuce cultivars (Scarlet and Cristal) done in triplicate with five plants per trial. The lettuce plants were growth in trapezoid-shaped PVC channels filled with coconut fiber substrate and organic compost (2:1) for 35 days after transplanting. The experimental results indicated that irrigation with 30% sewage effluent diluted in tap water gives higher growth and yield of lettuce. The Cristal cultivar shows growth, soluble solids, and chlorophyll higher than the Scarlet cultivar. The application of treated domestic effluent does not affect the post-harvest quality of the lettuce to both cultivars.

The region of the Zona da Mata of Minas Gerais stands out in the production of vegetables. To achieve the success in this activity, it is important to choose suitable cultivars and apply irrigation correctly. This study aimed to determine the optimum irrigation depth and evaluate new commercial arugula cultivars in the Zona da Mata of Minas Gerais. The cultivation was carried out in a greenhouse during three cycles with periods of 33 (January 11, 2016 to February 12, 2016), 36 (March 1, 2016 to April 5, 2016), and 36 (April 12, 2016 to May 17, 2016) days. The experimental design was a randomized complete block design with five replications, five irrigation depths (50, 75, 100, 125, and 150% of the crop evapotranspiration-ETc) in the plots, and three arugula cultivars (Antonella, Cultivada, and Folha Larga) in the subplots. A drip irrigation system was used. The parameters evaluated were root depth, root fresh mass, plant water potential, leaf temperature, number of commercial leaves, total number of plants, fresh shoot mass, and water use efficiency. Arugula cultivars did not present differences in their agronomic characteristics. An irrigation depth of the 50% ETc is recommended if the soil moisture is under the field capacity at the beginning of the arugula cycle.

The aim of the study was to evaluate the chemical, physical and nutritional composition and sensory acceptability of different sweet potato cultivars to classify the best genotypes for human consumption. We evaluated ten genotypes extracted from the Germplasm bank of Midwest State University, Brazil. The cultivars were evaluated regarding their sensory acceptability and chemical (reducing sugar; nonreducing sugar; total sugar; pH; total soluble solids; titratable acidity; total soluble solids/titratable acidity ratio; and instrumental colour) and nutritional composition (moisture; ash; protein; lipid; carbohydrate; energy value; total carotenoid; and ascorbic acid). Greater scores (p < 0.05) for overall acceptance were obtained for the white pulp genotypes Amorano, Júlia, UGA 45, and UGA 49. There was a statistical difference (p < 0.05) in the chemical and nutritional composition of sweet potatoes, except for the pH values. Generally, tuber have a light colour (values of L* greater than 50) with a yellow shade (b*) and green subshade (negative a* values). The exception was noticed in the UGA 34 genotype, which presented a higher red shade (positive a* value) and a yellow subshade. The cultivars more indicated for human consumption were the UGA 34 (favorable nutritional profile), UGA 45 (better acceptability and favorable chemical and nutritional composition), and Amorano (better acceptability and favorable chemical composition). On the other hand, the UGA 29 genotype may be characterized as the less appropriated for consumption. That, due to its less acceptance from the consumers and an inferior chemical and nutritional characterization. We conclude that the Brazilian sweet potato cultivars more indicated for human consumption are the UGA 34, UGA 45 and Amorano, considering that present more favorable chemical, nutritional and sensory acceptability characteristics. The UGA 29 genotype may be characterized as less recommended for consumption.

In this study, we aimed to evaluate the effect of the addition of different probiotics to commercial diets for piglets on diet digestibility, total bacterial count (TBC) of faeces, Clostridium count and growth performance. In the digestibility assay, 24 entire male pigs with an average initial body weight of 18.8 ± 0.87 kg were housed individually in metabolism cages and distributed in a completely randomised experimental design; this consisted of three treatments (probiotic-free commercial feed; commercial feed with the addition of 0.2% probiotic containing a blend of microorganisms; commercial feed with the addition of 0.1% yeast-based probiotic Saccharomyces cerevisiae boulardii) and eight replicates. The digestibility of the feeds was determined. At the end of the experiment, 25 grams of faeces were collected for microbiological analysis. In the subsequent experiment, 150 crossbred piglets (entire males and females), weaned at 21 days of age and having an average initial body weight of 6.81 ± 0.71 kg were distributed in a randomised complete block design, with six treatments repeated twice in the first and thrice in the second block, totaling five replicates and five pigs per experimental unit. The treatments, arranged in a 3 x 2 factorial arrangement, consisted of a combination of the three experimental diets used in the digestibility test and two genders. The growth performance in the nursery was evaluated during the following phases: pre-starter I (21 to 29 days), pre-starter I and II (21 to 40 days) and the total period (21 to 63 days). There was an effect (p < 0.05) of the diets on the digestible protein and the logarithm of the TBC. There was no effect (p > 0.05) of the interaction or the diets on the growth performance of the pigs in any of the phases. Both in the entire experimental period and in the pre-starter I and II phases, male pigs presented better feed conversion (p < 0.05) than females. There was an improvement in the apparent digestibility of the crude protein of the feed when the pigs were fed commercial feed containing probiotics. Pigs fed commercial feed containing probiotics based on yeast Saccharomyces cerevisiae boulardii presented a reduced TBC in their faeces. Commercial feed containing probiotics did not influence the growth performance parameters of nursery phase piglets.

Published: June 2019

Sulfur deficiency in soils has become a worldwide concern for agricultural production. This study aimed to evaluate the concequence of variable sulfur source and dosing on the nutritional status and production of Piatã forage in a dystrophic Ultisol. The experiment was arranged in a completely randomized block design with four replications. The 4 x 5 factorial treatments consisted of four sulfur sources (elemental sulfur pastilles [ESPA], gypsum [GY], gypsite [GI], and elemental sulfur powder [ESPO]) and five sulfur doses (0, 50, 100, 150. and 200 mg kg-1). The sulfur applications resulted in similar maximum shoot dry mass (SDM) production (16.66 to 17.69 g pot-1) with all sources. However, Piatã grass achieved maximum production in the treatments with 112 mg kg-1 of GI, 118 mg kg-1 of GY and ESPA, and 146 mg kg-1 of ESPO. The number of tillers, the leaf:stem ratio, and SPAD increased with increasing sulfur dose. The greatest increments of root dry mass (RDM) and of the tiller number were obtained with the ESPO source. Macronutrient concentrations in shoot dry mass tissue were in the order K > N > Ca > P > S > Mg. Low sulfur supply resulted in decreased Piatã grass growth with all sulfur sources tested. Differential responses were found with applications of different sulfur sources for SDM, RDM, and tillers number. The sources did not alter the leaf:stem ratio or SPAD index.

Published: June 2019

This study aimed to evaluate the production, the physical and nutritional composition of forage and silage, as well as the profitability and aerobic stability of different winter cereals harvested at the stage of floury grain. The experimental design was a 2x7 factorial randomized block design, with two forms of foods (fresh forage and silage) and seven genotypes, with four replications. The genotypes used were the white oat (Avena sativa) cv. URS Taura; barley (Hordeum vulgare) cv. BRS Brau and cv. BRS Cauê; wheat (Tricticum aestivum) cv. CD 1440; rye (Secale cereal) cv. BR 01; and triticale (X Triticosecale) cv. IPR 111 and cv. BRS Saturno. The materials were harvested during the stage of floury grain. In forage evaluation, rye showed the highest (P < 0,05) dry biomass production (7,100 kg ha-1), but with a higher percentage of stem (46.7%) in dry matter, implying higher ADF (44.69%) in relation to other cereals. The forage of the white oats cv. URS Taura and triticale cv. IPR 111 provided the best nutritional quality compared to the other evaluated cereals, but in the resulting silage, only triticale remained with forage-like characteristics. It was clear the superiority of barley cv. BRS Cauê, wheat cv. CD 1440 and rye cv. BR 01 regarding the maintenance of aerobic stability (160 hours), while the other silages lost their stability within 32 hours. Rye cv. BR 01 and triticale IPR 111 presented the highest production of recovered dry biomass (5,402 and 5,352 kg ha-1 respectively), barley cv. BRS Cauê and oat URS Taura provided higher cost of production per kg-1 dry biomass, both with R$ 0.29 and higher cost per kg of recovered dry biomass R$ 0.45 and 0.37 respectively. There are several factors to consider when choosing the winter species for silage production, and future studies can fully elucidate these factors.

Published: June 2019

We aimed to evaluate environmental effects on pre-weaning traits of Santa Gertrudis cattle. We used 213 standardized records for adjusted 205-day weight at weaning (W205), average daily gain from birth to weaning (AGD), and number of days to gain 160 kg from birth to weaning (D160), obtained from the Santa Gertrudis Breeders' Association for animals born between 1990 and 1997. The files were edited with information regarding cow age at calving (CAC) and contemporary group (CG), for which the effects of year and season of birth, animal category, herd, and sex were considered. It was observed that cow age at calving, which had linear and quadratic effects, and effect of contemporary group were significant (P < 0.0001) for the evaluated traits. Estimated averages were 198.05 ± 40.64 kg, 0.790 ± 0.198 kg day-1, and 288.05 ± 67.18 days for W205, ADG, and D160, respectively. Males were 4.67 kg heavier (197.17 kg) than females, on average. Regarding the animal category effect, the classified females were 2.3% heavier than the unclassified, on average. On average, animals born in the dry season were 1.6% lighter than those born in the rainy season (197.18 kg). Thus, environmental effects are important and should be considered in any analysis model.

Published: June 2019

This study aimed to assess the probability of meat tenderness in confined cows. For this purpose, CAPES and SciELO platforms were searched for papers under this subject published in Brazil between 2000 and 2015. A total of 43 articles were found, of which eleven were used. Those selected approached the finishing of confined cows and specified animal genetic group, breed, and age at experiment start. Moreover, all these studies evaluated sensory and organoleptic characteristics of meat, following the same method. Each variable was analyzed by logistic regression, using the LOGISTIC procedure of SAS. The factors were evaluated by odds ratio (OR), in which changes in the probability of meat tenderness were estimated by means of an add-on function in regression variable units. Animal age at the beginning of termination, percentages of zebuine blood and heterozygosity, and marbling score are factors that affect (p < 0.30) the chance of beef tenderness. The probabilities of obtaining a tender meat increase when age at termination beginning and zebuine genotype participation are reduced, as well as when heterozygosity (via crosses) and meat marbling score increases.
Does Love Money Affect Vocational Behavior? Empirical Evidence from Italian Entrepreneurs
Authors: Matricano Diego , Sorrentino Mario
Published: June 2019

The present paper aims to investigate the relevance that love money – i.e. financial resources provided by family, friends, and fools – can have on vocational behavior, standing for personal goals that are occupational in nature. In particular, the relationship between the above-cited financial resources and “core goals” (i.e. the survival of entrepreneurial firms) is tested by leveraging on second-hand data about Italian entrepreneurs retrieved from Global Entrepreneurship Monitor – GEM website and referring to the years 2012-2014 and by applying estimated Logit models.

Achieved results show that financial resources provided by fools do not affect the survival of entrepreneurial firms. On the contrary, financial resources provided by family and friends do it. Noticeably, the impact of financial resources provided by family or by friends varies in terms of intensity and according to entrepreneurial profiles, in particular to gender and age. After highlighting the main limitations of this paper, some hints for further research are proposed in the last part of the paper.
Rosticidade televisiva
Authors: Gomes Marcelo Salcedo
Published: June 2019

Refletimos aqui sobre a natureza do devir-rosto nos processos midiáticos, especificamente em panoramas televisivos. A partir da invenção do conceito de rosticidade, propomos a discussão de uma qualidade comunicacional virtual que se atualiza em tecnoimagens de rosto ou algo que toma o lugar de rosto para se fazer reconhecer como autêntico. Procedemos à dissecação de imagens dos telejornalísticos Estúdio i e SBT Brasil, através da metodologia das molduras de Kilpp (2003), procurando disdiscretizar os elementos técnicos e estéticos que trabalham em favor da “máquina abstrata” rostizante postulada por Deleuze e Guattari (1996). A dissecação aponta que os sentidos identitários enunciados pela produção de certas imagens televisivas se fazem rosto na medida que evocam padrões de um imaginário tecnocultural assimetricamente compartilhado.
Jornalismo literário de viagem internacional: um panorama do cenário autoral brasileiro
Authors: Ritter Eduardo
Published: June 2019

Um dos genêros literários mais antigos é a narrativa de viagem. Assim como jornalistas, especialmente os que praticaram o estilo que ficou conhecido como New Journalism, trouxeram técnicas e métodos do romance ficcional para produzir os livros-reportagens, as narrativas de trânsito humano também ganharam espaço dentro do que hoje é chamado Jornalismo Literário. Destarte, a presente pesquisa compartilha o mapeamento feito apresentando o cenário de jornalistas brasileiros que relatam viagens internacionais no formato de livro. Tal levantamento, que integra o projeto de pesquisa Jornalismo Literário de Viagem: Narrativas de Jornalistas Transitando pelo Mundo, foi feito a partir da Análise de Conteúdo, de Bardin (2011) e Hercovitz (2007). Já a base teórica parte principalmente das premissas de Martinez (2016) e Lima (2004). No total, foram identificadas 60 obras do gênero produzidas por 35 jornalistas-escritores viajantes.
A moda retrô e a fascinação com o nazismo: Lacombe Lucien e a crítica de cinema francesa
Authors: Adamatti Margarida Maria
Published: June 2019

Quando Louis Malle escolheu colocar nas telas o tema da cooptação do jovem camponês Lacombe Lucien (1974) em vez de frisar a resistência francesa, ele adentrou num campo minado com a crítica de cinema da revista Cahiers du Cinéma. Num contexto de crescente politização, a publicação dedicou ao filme artigos em torno das teorias da enunciação, da semiologia, da criação de estereótipos e especialmente em torno da onda retrô. Por mais de um ano, o cineasta foi acusado de estar fascinado pelo nazismo ao invés de denunciá-lo. O assunto tabu para os franceses acendeu um debate intenso entre Pascal Bonitzer, Serge Daney, Pascal Kané, Serge Toubiana, Michel Foucault e Marc Ferro, que analisamos nesse artigo para ampliar a compreensão da metodologia da crítica de cinema francesa daquele momento.
Communication modeling: considering complexity in digital technology policies
Authors: Holanda Giovanni Moura de , Alves Angela Maria
Published: June 2019

Políticas voltadas a tecnologias digitais raramente tendem a considerar modelos de comunicação abrangentes, tampouco o modo como a informação é realmente gerada e assimilada em um processo comunicacional. Normalmente, os modelos que descrevem a comunicação são inteiramente circunscritos pela dimensão técnica. Em interações mediadas pela tecnologia, a efetividade entre a intenção de uma mensagem e como ela é recebida e compreendida por um usuário é fundamental para a criação de conhecimento e a construção de intersubjetividades, e pode ser decisiva em políticas de TIC. Interatividade, múltiplos contextos e subjetividade são fatores condicionantes desse processo complexo. Este artigo apresenta uma reflexão sobre como modelos de comunicação que incluem esses fatores podem contribuir para o entendimento fenomenológico da comunicação, cobrindo lacunas de modelagens usualmente adotadas, cujo foco atém-se predominantemente à dimensão tecnológica ou de comunicação de massa. Uma compreensão mais ampla e multidimensional da complexidade inerente ao processo comunicacional pode suportar com maior eficiência a formulação de políticas de tecnologias digitais.

Monitoramentos temporais da biodiversidade vegetal são cada vez mais necessários. Diante do exposto, este estudo buscou avaliar se há alterações florísticas e estruturais em fragmento de Cerradão, município de Rio Verde, estado de Goiás, Brasil, em intervalo de tempo de três anos. Foram realizados dois inventários: o primeiro foi realizado no ano de 2011, onde foram estabelecidas 20 parcelas de 100 m² cada; o segundo inventário foi realizado em 2014, onde todos os indivíduos do primeiro levantamento foram remedidos e, aqueles que atingiram os critérios mínimos de inclusão, foram registrados. As alterações ocorridas foram avaliadas por comparações entre: área basal, famílias, gêneros e espécies, número de indivíduos, densidade, dominância, frequência, valor de importância, equabilidade de Pielou e diversidade de Shannon. Foram registradas poucas alterações, e estatisticamente, não houve diferença entre os inventários. Foi excluída a família Calophyllaceae e incluída Burseraceae e, registrou-se a exclusão de seis gêneros e inclusão de três. Em 2011, foram inventariadas 64 espécies, enquanto que em 2014 foram registradas 61. Somaram-se 43 recrutas, enquanto que o número de indivíduos mortos foi de 81. Sendo assim, o total de indivíduos amostrados no primeiro inventário (n = 394) foi superior ao segundo (n = 356). Para detecção de mudanças quanto ao recrutamento e mortalidade de espécies neste ecossistema, recomenda-se que seja estendido o período de monitoramento, com a realização de maior número de inventários.

Este artigo se propõe a verificar se as cooperativas incorrem na prática de gerenciamento de resultados com vistas a evitar divulgar perdas. Também, pretende-se analisar a relação entre eficiência e este tipo de gerenciamento de resultados nestas instituições a fim de compreender a adoção dessas práticas com finalidades estratégicas. Para tal, utilizou-se o teste qui-quadrado, numa amostra composta por 90 observações referentes às cooperativas ligadas à Confederação Nacional das Cooperativas Centrais Unicred’s (UNICRED), no período de 2009 a 2014. Os resultados indicaram que há relação entre o gerenciamento de resultados para evitar divulgar perdas e os escores de eficiência nas cooperativas de crédito. A faixa de eficiência que mais gerenciou seus resultados a fim de evitar divulgar perdas foi a de eficiência na faixa mediana.
Identidade e imagem por meio do processo de comunicação: um estudo da percepção do associado de uma cooperativa de crédito
Authors: Breda Vitor Sanches
Published: June 2019

Dada a frequente confusão entre instituições financeiras cooperativas e instituições financeiras bancárias, este trabalho cumpre a finalidade de identificar a formação da imagem, que resulta da transmissão de mensagens de suas características próprias (identidade), de uma cooperativa de crédito em seu público alvo, os associados. Para atingir o objetivo proposto realizou-se uma investigação caracterizada como qualitativa e quanto aos procedimentos técnicos como um estudo único de casos em uma cooperativa filiada ao sistema SICREDI. Os dados foram coletados por meio de entrevistas, observação participante e análise de documentos. Os resultados apontam a percepção das falhas que impactam nos processos de comunicação, de construção da imagem e de formação da identidade pelos associados, como a falta de unidade entre as cooperativas filiadas ao sistema, as diferenças culturais e o perfil dos associados, assim como a inaptidão dos colaboradores na apresentação da marca e do cooperativismo ao associado.
Cooperativismo: uma análise da gestão de três cooperativas de Erechim/RS e dos indicadores econômico-financeiros de 2006 a 2015
Authors: Giacomin Juciléia , Boetler Carlos , Fiabani Fernando , Sandri Oliomar
Published: June 2019

O cooperativismo contribui com o crescimento social e econômico do país, atingindo todos os segmentos, de forma direta ou indireta. Há algumas atividades em que as cooperativas seguem um regramento imposto pelo Estado, que muito contribui para a gestão. O indicador econômico financeiro permite uma análise mais aprofundada dos resultados das Cooperativas, sendo que esta pode ser analisada sob vários aspectos, acompanhando os impactos ocorridos ao fechamento de cada período e assim utilizá-lo como ferramenta para determinar ações para a tomada de decisão. Desta forma, o presente estudo tem por objetivo analisar através de indicadores econômicos e financeiros a gestão das três maiores cooperativas de Erechim em seus ramos de atuação Infraestrutura, Credito e Agropecuária no período de 2006 a 2015. Trata-se de pesquisa descritiva, e quantitativa quanto a abordagem do problema. Pode-se concluir que a análise dos indicadores nos anos abordados é capaz de transmitir a evolução das cooperativas e as interferências das suas gestões ao tentar crescer, expandir a atuação ou mesmo recuperar uma situação difícil herdada de exercícios anteriores.

Published: June 2019

Este artigo tem como objetivo identificar características empreendedoras nos gestores de cooperativas com sede na região central do Rio Grande do Sul. Considerando a relevância das cooperativas para a economia brasileira, buscamos a relação do empreendedorismo com as cooperativas, por meio da análise das características de seus gestores. Assim, apresentam-se o conceito de empreendedorismo e também a descrição das principais características empreendedoras de acordo com Filion (1999). Busca-se de forma clara e objetiva, expor como aconteceu o desenvolvimento da atividade empreendedora no mundo, e mais especificamente como se difundiu no Brasil. As principais áreas do conhecimento do empreendedorismo, as funções do empreendedor, a importância do plano de negócios e os tipos de empreendedorismo também são abordados. A evolução histórica do cooperativismo é mostrada, porém de forma sintética. Um questionário foi aplicado aos gestores de cooperativas para a coleta de dados.

A pesquisa objetivou caracterizar os Empreendimentos Econômicos Solidários de Artesanato (EESA) formais do estado da Bahia que se uniram para promover a produção ou produção e comercialização de seus produtos. A metodologia perpassou por uma abordagem quantitativa, partindo da base de dados do segundo mapeamento do Sistema Nacional de Informações de Economia Solidária (SIES), com um recorte nas organizações formais de artesanato. Os resultados atestam que, os EESA baianos se expressa, em sua maioria como associações, que por sua natureza jurídica não podem comercializar, situação também demostrada pela baixa viabilidade econômica dessas organizações. Em paralelo a isso, os obstáculos de atuação no mercado estão ligadas à gestão, materializada pela baixa participação em rede, dificuldade de acesso ao crédito e da atuação em coletividade, esse último, princípio que fundamenta a existência das organizações coletivas.

The second messenger signaling molecule cyclic diguanylate monophosphate (c-di-GMP) drives the transition between planktonic and biofilm growth in many bacterial species. Pseudomonas aeruginosa has two surface sensing systems that produce c-di-GMP in response to surface adherence. Current thinking in the field is that once cells attach to a surface, they uniformly respond by producing c-di-GMP. Here, we describe how the Wsp system generates heterogeneity in surface sensing, resulting in two physiologically distinct subpopulations of cells. One subpopulation has elevated c-di-GMP and produces biofilm matrix, serving as the founders of initial microcolonies. The other subpopulation has low c-di-GMP and engages in surface motility, allowing for exploration of the surface. We also show that this heterogeneity strongly correlates to surface behavior for descendent cells. Together, our results suggest that after surface attachment, P. aeruginosa engages in a division of labor that persists across generations, accelerating early biofilm formation and surface exploration.

Published: June 2019

A integração e a cooperação entre os países consistem num esforço dos envolvidos em combater as dificuldades básicas de forma harmônica e duradoura, resultando no desenvolvimento dos países. O presente artigo tem como objetivo estudar a existência de políticas públicas entre as cidades fronteiriças de Tabatinga (Brasil) e Letícia (Colômbia) para o desenvolvimento destas regiões, visto que as melhorias das condições básicas de vida excedem a transformação econômica, política e social de cada região. A análise foi dual: perscrutou o comportamento dos estados e o nível de interdependência entre eles, explorando a regulamentação de iniciativas tomadas pelo governo dos envolvidos, desvelando, ou não, o desenvolvimento equilibrado e justo entre eles, e o papel dos instrumentos legais que instruem a cooperação de políticas públicas internacionais. O processo, portanto, demandou a análise do conteúdo presente nos tratados, livros e artigos acadêmicos. A partir das pesquisas, reconheceu-se a necessidade de uma diligência por parte dos dois países para a propagação da cooperação internacional em face da carência de ações governamentais por parte das lideranças e das organizações internacionais dos dois países.Código JEL | F59; O19; Q58.

Rooftop water harvesting is an ideal technique to collect and store rainwater for drinking purposes. However, with time, in spite of all precautions, there is a possibility of development of microbes in stored water, making it unsafe for drinking. An attempt was made at Navsari Agricultural University, Gujarat to design the rooftop water harvesting system in such a way that stored water meets the annual water demand maintaining the quality of water at minimum cost. The water harvesting system was constructed at six locations and water quality in the storage tanks was monitored at regular intervals. Physical, chemical and bacterial quality of harvested rainwater was evaluated in laboratory and the water was found to be of excellent quality. However, microbial growth was found to be present at few places over the time. Laboratory study was undertaken to find economical solution to remove microbes from the stored water before consumption using copper vessel, silver strip of 30 cm × 10 cm × 0.03 cm size, commercially available cloth filter, earthen pot, and control (without any treatment). The results revealed that copper vessel showed maximum inhibitory effect on coliform as well as total bacterial count when water was stored for 12 h and 24 h. Though, there was a slight increase in copper residue, but it remained within the permissible limits. Therefore, vessel made up of copper could safely be used for antimicrobial treatment to purify the drinking water. The methodology could be useful to meet the precariously deteriorating potable water situation in rural areas especially for the poor people of developing economies.

This paper is an assessment of aerosols impact on solar potential available in Burkina Faso in 2017. Three measurement stations were selected from the North to the South according to the climatic zones, with sites at Dori (14.035°N, 0.034°W) in the North, Ouagadougou (12.20°N, 1.40°W) in the Center and Gaoua (10.29°N, 3.25°W) in the Southwest, respectively. This study is based on in-situ measurements, satellite observations and a tropospheric standard model of the Streamer radiative transfer code of atmospheric particles. The results show a high availability of solar irradiation with average monthly values ranging between 4.46 kWh/m²/d and 6.82 kWh/m²/d. The most favorable periods with maximum radiation are observed in Spring in March and in Fall in October. Yet, the qualitative comparison between the evolution of aerosols and that of solar potential clearly shows aerosols capacity to influence the radiation at the crossing of the atmosphere. Thus, the aerosols maxima correspond to the solar potential minima. Moreover, a comparison between the day cycles of solar radiation and those of the simulation model shows a good accuracy of the Streamer code to estimate the solar flows at the surface in a standard atmosphere without clouds in Burkina Faso.However, a quantification of the aerosol impact by the Streamer code reveals a reduction in the normal direct flow compared to clear days defined by aerosol optical depth (AOD) less than 0.2 (AOD<0.2) of nearly 75.04% at the Dori site in the North, 57.33% at the Ouagadougou site in the Center and 40.89 % at the Gaoua site in the Southwest during polluted days corresponding to AOD higher than 0.8.This corresponds to an increase in the diffuse flow of 279.69 W/m², 246.05 W/m² and 226.09 W/m², respectively calculated on the same sites. In case of a mixed day (0.2 <AOD <0.8), this decrease in direct solar flow is estimated at 41.25%, 22.11% and 37.13% with an increasein the diffuse solar flux of 115.04 W/m², 150.43 W/m² and 79.58 W/m² at the sites of Dori, Ouagadougou and Gaoua, respectively.

Aims: The study was aimed at determining subclinical malaria and estimating reticulocyte count in apparently healthy female undergraduate students of Rivers State University, Port Harcourt.

Study Design:  This is a non-randomized, comparative case-control study.

Place and Duration of Study: The study was conducted using female students residing at the hostels of Rivers State University, Port Harcourt. Analysis was carried out at the Haematology Laboratory, Department of Medical Laboratory Science, Rivers State University, Port Harcourt, Nigeria, between July and August, 2018.

Methodology: For the subjects used in this study, a total of 32 students (32%) that were diagnosed of having Plasmodium falciparum malaria infection were used as test subjects, while a total of 68 students (68%) that were diagnosed to be Plasmodium falciparum negative, and without malaria, were used as control. Thick and thin blood films examination using Giemsa staining technique was used to detect and calculate the malaria parasite density while a thin blood film examination using new methylene blue staining technique was used to evaluate the reticulocyte count in the blood.

Results: The reticulocyte count of test subjects (subjects with Plasmodium falciparum malaria) was 0.15 ± 0.04% and that of control subjects (subjects without any malaria parasite) was 0.31 ± 0.08%. The test subjects had significantly lower reticulocyte count (p ˂ 0.0001) than the control subjects. The age range “15-19” years had the highest malaria parasite density of 0.52 ± 0.18%, while “25-29” years had the least parasite density of 0.33 ± 0.24. There was no statistical variation in malaria parasite density according to age ranges (p = 0.13; p ˃ 0.05). However, the age range of “15-19” years had the lowest reticulocyte count as most of the female students within this age group were diagnosed to have been infected with malaria parasite.

Conclusion: This study revealed that reticulocyte counts of malaria (Plasmodium falciparum) infected individuals decreased when compared to those without malaria parasite and this decrease was statistically significant. There was no statistical significant variation in malaria parasite density irrespective of age ranges. Prophylaxis for malaria in such settings would be an efficient means of preventing infectious reservoirs and higher rates of subclinical malaria infection.
