Mercado de rosas no Distrito Federal : socioeconomia e determinantes da oferta

Dissertação (mestrado)—Universidade de Brasília, Faculdade de Tecnologia, Departamento de Engenharia Florestal, Programa de Pós-Graduação em Ciências Florestais, 2018.As flores e plantas ornamentais são produtos importantes para o mercado brasileiro. Elas são geradoras de renda e trabalho tanto para os produtores quanto para seus colaboradores. O Brasil tem crescido nesse setor para a exportação das flores e plantas ornamentais, mas o principal mercado é o interno. A rosa é a preferida dos consumidores no setor de floricultura, sendo a mais vendida para presentes em datas comemorativas como Dia das Mães e Dia dos Namorados. O presente estudo teve por objetivos: (1) Descrever o perfil socioeconômico dos produtores de flores e plantas ornamentais no Distrito Federal; 2) Determinar a oferta de rosas e plantas ornamentais no Distrito Federal; 3) Identificar o(s) fator(es) que afeta(m) o mercado local de rosas. Este estudo realizou uma abordagem comparativa, por meio de análise bidimensional. Para análise dos determinantes da oferta de rosa, utilizou-se a modelagem econométrica. Os resultados indicaram que os produtores de do Distrito Federal são de pequena escala e não têm na produção de plantas ornamentais sua principal atividade geradora de renda. Os determinantes da oferta de rosas no mercado do Distrito Federal foram a quantidade do lírio e seu preço; o preço da gérbera, a quantidade do lisianthus e a sazonalidade. O lírio mostrou-se um bem relacionado com com a rosa sendo considerado junto com o lisianthus bens complementares.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES).Flowers and ornamental plants are important products for the Brazilian market. They generate income and work for producers and their collaborators. Brazil has growing in this sector for flowers and ornamental plants export, but the main market is the local market. The rose is the favorite of consumers in the floriculture sector, being the most sold for gifts on commemorative dates as Mother's Day and Valentine's Day. The objectives of this study are: (1) To describe the socioeconomic profile of flowers and ornamental plants producers in the Distrito Federal; 2) To determine the supply of roses and ornamental plants in the Distrito Federal; 3) Identify the factor(s) that affecting the local market for roses. In this study is performed a comparative approach using an approaching by two-dimensional analysis. On analysis of the determinants of the rose supply, is used the econometric modeling. The achieved results show that the producers of the Distrito Federal are small scale and do not have ornamental plants as their main income generating activity. The determinants of the supply of roses in the market of the Distrito Federal, in order, were the quantity of the lily and its price, the price of the gerbera, the amount of lisianthus and the seasonality. The lily was shown to be well related to the rose being considered with the lisianthus, as complementary goods

Viral entry and translation in brain endothelia provoke influenza-associated encephalopathy

The version of record of this article, first published in Acta Neuropathologica, is available online at Publisher’s website: https://doi.org/10.1007/s00401-024-02723-z.Influenza-associated encephalopathy (IAE) is extremely acute in onset, with high lethality and morbidity within a few days, while the direct pathogenesis by influenza virus in this acute phase in the brain is largely unknown. Here we show that influenza virus enters into the cerebral endothelium and thereby induces IAE. Three-weeks-old young mice were inoculated with influenza A virus (IAV). Physical and neurological scores were recorded and temporal-spatial analyses of histopathology and viral studies were performed up to 72 h post inoculation. Histopathological examinations were also performed using IAE human autopsy brains. Viral infection, proliferation and pathogenesis were analyzed in cell lines of endothelium and astrocyte. The effects of anti-influenza viral drugs were tested in the cell lines and animal models. Upon intravenous inoculation of IAV in mice, the mice developed encephalopathy with brain edema and pathological lesions represented by micro bleeding and injured astrocytic process (clasmatodendrosis) within 72 h. Histologically, massive deposits of viral nucleoprotein were observed as early as 24 h post infection in the brain endothelial cells of mouse models and the IAE patients. IAV inoculated endothelial cell lines showed deposition of viral proteins and provoked cell death, while IAV scarcely amplified. Inhibition of viral transcription and translation suppressed the endothelial cell death and the lethality of mouse models. These data suggest that the onset of encephalopathy should be induced by cerebral endothelial infection with IAV. Thus, IAV entry into the endothelium, and transcription and/or translation of viral RNA, but not viral proliferation, should be the key pathogenesis of IAE

Avaliação do conteúdo de carotenoides totais e compostos cianogênicos em híbridos de mandioca das gerações 2007 e 2008.

De origem brasileira, a cultura da mandioca (Manihot esculenta Crantz.) apresenta grande importância socioeconômica para o Brasil e para o mundo (FOLEGATTI et al., 2005), sendo base energética para mais de 700 milhões de pessoas, em vários países tropicais e subtropicais (MARCON et al., 2007). No Brasil, o consumo in natura é responsável pela alimentação das populações mais carentes, sendo o teor de compostos cianogênicos contido nas raízes um dos fatores que definem a finalidade de uso da mandioca (PONTE, 2008). É com base na concentração de compostos cianogênicos, que as variedades são classificadas em 'mansas' e 'bravas'. As mandiocas mansas, destinadas ao consumo fresco, apresentam menos de 100 ppm de ácido cianídrico na polpa crua das raízes e são denominadas como 'mandioca de mesa', 'macaxeira', 'aipim' ou 'mandioca doce'. As bravas apresentam mais de 100 ppm de ácido cianídrico na polpa crua das raízes e devem ser processadas antes do consumo, sendo designadas como 'mandioca amarga' e destinam-se à industrialização (PAZINATO et al., 2003).Melhoramento genético.

Melhoramento de mandioca para aumento do teor de betacaroteno.

O objetivo desse trabalho foi avaliar o teor de carotenoides e compostos cianogênicos em mandioca para mesa. Foram avaliados 78 clones resultantes da autofecundação de 16 acessos (BGM 61, BGM 66, BGM 878, BGM 893, BGM 913, BGM 952, BGM 971, BGM 991, BGM 1137, BGM 1146, BGM 1186, BGM 1702, BGM 1706, BGM 1708, BGM 1709 e BGM 1776) do Banco de Germoplasama da Embrapa Mandioca e Fruticultura. Os teores de carotenoides variaram de 4,43 a 16,12 µg.g-1, enquanto os de compostos cianogênicos variaram de 60,8 a 298,1 µg.g-1. Entretanto, os teores de compostos cianogênicos desses clones de maior teor de carotenoides tenderam a ser maiores que 100 ppm, e assim, eles não podem ser selecionados como mandioca mansa. Como os clones que têm teores baixos de HCN e altos teores de carotenoides ainda têm que atender a outros critérios relacionados à qualidade, torna-se difícil identificar um que atenda a todos esses critérios. Assim, a estratégia que está sendo adotada é o intercruzamento entre os clones que possuem teores elevados de betacaroteno e baixos teores de compostos cianogênicos, visando continuar obtendo progresso no melhoramento para aumento do teor de betacaroteno, mantendo baixo o teor de compostos cianogênicos.PDF.

Can i have a second child? dilemmas of mothers of children with pervasive developmental disorder: a qualitative study

<p>Abstract</p> <p>Background</p> <p>Pervasive developmental disorder (PDD) has an uncertain etiology, no method of treatment, and results in communication deficiencies and other behavioral problems. As the reported recurrence risk is 5%-10% and there are no methods of either prevention or prenatal testing, mothers of PDD children may face unique challenges when contemplating second pregnancies. The purpose of this study was to explore the mothers' lived experiences of second child-related decision-making after the birth of a child with PDD.</p> <p>Methods</p> <p>The participants for this study were restricted to mothers living within the greater Tokyo metropolitan area who had given birth to a first child with PDD within the past 18 years. The ten participants were encouraged to describe their experiences of second-child related decision-making after the birth of a child with PDD on the basis of semi-structured interviews. Data analysis was performed by using Interpretive Phenomenological Analysis (IPA), which is concerned with understanding what the participant thinks or believes about the topic under discussion.</p> <p>Results</p> <p>We identified two superordinate themes. The first was balancing hopes and fears, in which hope was the potential joy to be gained by the birth of a new child without PDD and fears were characterized as uncertainty of PDD and perception of recurrence risk, burden on later-born children, and negative effects on a child with PDD.</p> <p>The second superordinate theme was assessing the manageability of the situation, which was affected by factors as diverse as severity of PDD, relationship between mother and father, and social support and acceptance for PDD. Our 10 participants suffered from extreme psychological conflict, and lack of social support and acceptance for PDD created numerous practical difficulties in having second children.</p> <p>Conclusions</p> <p>Our participants faced various difficulties when considering second pregnancies after the birth of children with PDD in the Japanese society. As lack of social support and acceptance for PDD also played a large role in second child-related decision-making, creating a social environment that more fully accepts those disabled and providing flexible support systems for families of children with PDD are crucial.</p

子守帯の快適性評価 : 官能評価と接触圧からの検討

In this study, to design comfortable baby carriers, we determined the burden on the wearer. Sensory evaluation and contact pressure were used to evaluate five types of baby carriers. The test subjects were three healthy adult women who carried a dummy approximate to a six-month-old baby. The subjects evaluated the fit of the baby carrier immediately after putting it on, and then after an activity. They also evaluated the sense of burden on different parts of the body when wearing the carrier. Contact pressure was measured with airpack sensors while the subjects were walking or resting. The results show that the type of baby carrier affected the contact pressure and the fit in the vertical holding position. A correlation, r, of 0.554 was obtained between the fit and the largest contact pressure immediately after the baby carrier was worn. Further, the correlation between the largest contact pressure during the entire activity period and the fit after the activity increased to r=0.669. While wearing the carrier, the fit at the focus area of contact pressure worsened after the activity. These findings show that, when designing baby carriers, stabilizing and distributing contact pressure points will effectively improve the fit. The findings also indicate the usefulness of the largest contact pressure as a means of objectively evaluating baby carriers
