Get PDFABSTRAKSI: Makanan dan minuman merupaka n salah satu faktor yang menentukan kesehatan seseorang. Saat ini terdapat banyak produk makanan dan minuman instan yang beredar dan terbuat dari berbagai macam komposisi dan nutrisi. Komposisi dan nutrisi tersebut dapat menyebabkan berbagai macam dampak t erhadap konsumen, terutama bagi konsumen dengan riwayat penyakit tertentu. Pengetahuan masyarakat awam yang masih kurang akan dampak dari kandungan yang dimiliki oleh suatu produk dapat menyebabkan konsumsi dengan jumlah yang tidak seharusnya, dan apabila dibiarkan hal ini dapat memberikan dampak yang tidak diinginkankan bila terjadi. Upaya untuk menangani masalah tersebut di atas adalah dengan dibangunnya aplikasi sistem pakar yang dapat memutuskan apakah suatu produk dapat dikonsumsi atau tidak. Aplikasi ini membantu pengguna untuk dapat memutuskan aturan konsumsi suatu produk atau dapat menjadi sebagai bahan pertimbangan/referensi.KATA KUNCI: sistem pakar, android, forward chainingABSTRACT: Food and drink are one s of the factors that determine a pers on\u27s health.

Water table depth modulates productivity and biomass across Amazonian forests.
Get PDFWater availability is the major driver of tropical forest structure and dynamics. Most research has focused on the impacts of climatic water availability, whereas remarkably little is known about the influence of water table depth and excess soil water on forest processes. Nevertheless, given that plants take up water from the soil, the impacts of climatic water supply on plants are likely to be modulated by soil water conditio
Inheritance of seed size in watermelon populations.
Get PDFSeed sizeis an important agronomic trait and is applicable todifferent abilities. Small seeds guarantee the greater use of the pulp, while larger seeds facilitate sowing. However, there is little work on the genetic control of this characteristicin watermelon. The objective of this work was to study the seed size inheritance in watermelon populations by crossing contrasting genotypes, seeking to gain information to provide technical support during the selection of seed size for the development of new watermelon genotypes. The seed lengths of six populations, P1, P2, F1,F2,BC1and BC2, were measured using the GENES software segregating and nonsegregating generations procedure. This trait is controlled by two genes with incomplete dominance. In addition, depending on the populations studied, inheritance for the characteristicin question may behave differently. Nevertheless, the selection of superior individuals within populations can be performed based on this phenotype, which allows the exploitation of these individuals within breeding programs to develop lines or hybrids
Political Accidents in Zimbabwe
Get PDFOn 16 August 2011 Zimbabwe awoke to the news that retired General Solomon Mujuru, aka Rex Nhongo (his war alias), the former deputy commander of ZANLA (Zimbabwe African National Liberation Army) and independent Zimbabwe’s first black army commander, husband of the (then) vice-president, Joice Mujuru, longterm confidante of (then) president Robert Mugabe, and widely regarded as ‘kingmaker’ with the Zimbabwe African National Union Patriotic Front (ZANU PF), had died in a mysterious fire at his farm in Beatrice, 60 km south west of Harare. Just four days later, on 20 August, amid public statements of grief from across the political spectrum, and growing speculation about the cause of his death, Mujuru’s remains were buried at the National Heroes Acre in Harare at a huge state funeral attended by tens of thousands of people. After the ‘inexplicable, horrendous fire accident’ – as Mugabe then described it – there was only a ‘small pile of charred bones and ash’ to be buried, and workers reportedly needed ‘shovels to scrape his remains off the floor’. ‘Burnt beyond recognition’, unconfirmed reports suggested dental records were needed to confirm his identity; and (unusually for state funerals in Zimbabwe) the ‘coffin remained sealed’. Nevertheless, the closed casket did little to contain the plethora of rumours that emerged in the months that followed, which remain unresolved, despite police investigations and an official inquest
Antibacterial, cytotoxic and healing activity in vitro of endophytic fungi isolated from medicinal plants: Mimosa Tenuiflora (Willd.) Poir., Poincianella Pyramidalis Tul. and Acrocomia Aculeata (Jacq.) Lodd. Ex Mart.
No full textEndophytic microorganisms inhabit the interior of plant tissues and live in mutuality with the host plant, and represent a rich and little studied source of new biologically active natural compounds. The present study aimed to evaluate the in vitro antibacterial, cytotoxic and healing activities of endophytic fungi isolated from the plant species Acrocomia aculeata, Poincianella pyramidalis and Mimosa tenuiflora. It was a basic in vitro experimental research with a quantitative approach. Initially, the fungi isolates were evaluated in culture and microscopy, and the extracts were obtained from three endophytic fungi Penicillium sp. (isolated from Poincianella pyramidalis), Rhizoctonia sp. (Mimosa tenuiflora isolate) and a fungi isolated from Acrocomia aculeata that was not identified. Minimal Inhibitory Concentration of extracts against Gram positive and Gram negative bacteria was determined by the Broth Microdilution Method, in addition to cytotoxic activity by Methyltetrazolium (MTT) colorimetric method with J774 macrophages and 3T3 fibroblasts and in vitro healing activity of Scratch Assay. In the antibacterial assay, extracts of Penicillium sp. and Rhizoctonia sp. showed no activity against the bacteria tested, while the extract of the fungus isolated from A. aculeata presented antibacterial activity against S. epidermidis and S. aureus. Regarding cytotoxic activity, the extracts tested were nontoxic at all concentrations in front of J774 macrophages, but in 3T3 fibroblasts Penicillium sp. and unidentified fungus isolated from A. aculeata were toxic at concentrations of 100 and 50 μg/mL, Rhizoctonia sp. showed no toxicity at any of the concentrations tested. As for in vitro healing activity, the extracts presented positive healing activity with a migration rate similar to the control. It was concluded that medicinal plants A. aculeata, P. pyramidalis and M. tenuiflora, harbor endophytic fungi with different pharmacological potentials, are Penicillium sp., Rhizoctonia sp. and an unidentified fungus isolated from A. aculeata, which requires the application of molecular techniques for its identification, and the latter has activity against S. epidermidis and S. aureus, as well as in vitro healing activity. The data obtained encourage further studies to determine the substances that contribute to evidenced activities in the present study, aiming at a possible therapeutic application.Os micro-organismos endofíticos habitam o interior de tecidos vegetais e vivem em mutualismo com a planta hospedeira, e representam uma fonte rica e pouco estudada de novos compostos naturais biologicamente ativos. O presente estudo objetivou avaliar as atividades antibacteriana, citotóxica e cicatrizante in vitro de extratos de fungos endofíticos isolados das espécies vegetais Acrocomia aculeata, Poincianella pyramidalis e Mimosa tenuiflora. Tratou-se de pesquisa básica do tipo experimental in vitro com abordagem quantitativa. Inicialmente, os isolados fúngicos foram avaliados em cultura e microscopia, e os extratos foram obtidos a partir de três fungos endofíticos: Penicillium sp. (isolado de Poincianella pyramidalis), Rhizoctonia sp. (isolado de Mimosa tenuiflora) e um fungo isolado de Acrocomia aculeata que não foi identificado. Foi determinada a Concentração Inibitória Mínima dos extratos contra as bactérias Gram positivas e Gram negativas por meio do Método da Microdiluição em Caldo, além da atividade citotóxica pelo método colorimétrico Metiltetrazolium (MTT) com macrófagos J774 e fibroblastos 3T3 e a atividade cicatrizante in vitro por meio do Scratch Assay. No ensaio antibacteriano, os extratos de Penicillium sp. e Rhizoctonia sp. não demonstraram atividade frente às bactérias testadas, enquanto o extrato do fungo isolado de A. aculeata apresentou atividade antibacteriana contra S. epidermidis e S. aureus. Quanto à atividade citotóxica, os extratos testados foram atóxicos em todas as concentrações em macrófagos J774, mas em fibroblastos 3T3 os extratos de Penicillium sp. e do fungo não identificado isolado de A. aculeata foram tóxicos nas concentrações de 100 e 50 μg/mL, o de Rhizoctonia sp. não apresentou toxicidade em nenhuma das concentrações testadas. Quanto à atividade cicatrizante in vitro, os extratos apresentaram atividade cicatrizante positiva com taxa de migração semelhante ao controle. Concluiu-se que as plantas medicinais A. aculeata, P. pyramidalis e M. tenuiflora, abrigam fungos endofíticos com diferentes potenciais farmacológicos, são eles: Penicillium sp., Rhizoctonia sp. e um fungo não identificado isolado de A. aculeata, que necessita da aplicação de técnicas moleculares para sua identificação, e este último possui atividade contra S. epidermidis e S. aureus, bem como atividade cicatrizante in vitro. Os dados obtidos encorajam a realização de novos estudos a fim determinar as substâncias que contribuem para as atividades evidenciadas no presente estudo, visando uma possível aplicação terapêutica
Proposta de um modelo para o processo de desenvolvimento de produto para a indústria do vestuário fabricante de artigos de malha na modalidade de Private Label
Get PDFTese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia de Produção, Florianópolis, 2010Os estudos nos diversos setores da economia têm mostrado que a competitividade vem crescendo e as exigências dos consumidores são cada vez maiores. Com a intensificação da concorrência, os varejistas do vestuário com marca própria, aumentaram a frequência do lançamento de novos produtos e estão agregando mais elementos diferenciadores de moda para melhor atender os consumidores. Sendo assim, o processo de desenvolvimento de produto (PDP) é essencial para o sucesso do negócio. No entanto, constatou-se que os modelos encontrados na literatura são destinados para bens duráveis e os dedicados ao vestuário são apresentados de forma superficial e destinam-se às indústrias que lançam coleções para as principais estações climáticas do ano, o que não atende as necessidades das indústrias fabricantes para o varejo com marca própria. Reconhecendo este fato como um problema que necessita de uma investigação científica, esta tese objetiva propor um modelo de PDP que atenda estas indústrias, principalmente para as fornecedoras de produtos de malha. A revisão de literatura somada com a pesquisa de campo forneceu os requisitos para a construção do modelo que foi ilustrado graficamente de forma a permitir a visualização das macrofases, fases e também a integração do cliente e fornecedores em toda a extensão do processo. O detalhamento das atividades pertencentes a cada fase e as sugestões de mecanismos (ferramentas, métodos, normas e informações) foram dispostos em quadros que utilizou o IDEF0 (Integration Definition for Function Modeling) para modelar a proposta. A avaliação do modelo feita por dezessete especialistas através de vinte e cinco questões com base em onze critérios foram tratadas estatisticamente e mostraram-se adequadas ao seu propósito. Conclui-se com base nestes resultados que a proposta poderá ter aplicação prática nas indústrias fabricantes de produtos de malha, extensível a outros produtos, segmentos e ainda poderá contribuir com o meio acadêmico, especialmente para os cursos de moda, preenchendo uma lacuna existente na literatura de PDP para bens de consumo de vestuário
Multiple roles of motor imagery during action observation
Get PDFOver the last 20 years, the topics of action observation (AO) and motor imagery (MI) have been largely studied in isolation from each other, despite the early integrative account by Jeannerod (1994, 2001). Recent neuroimaging studies demonstrate enhanced cortical activity when AO and MI are performed concurrently (“AO+MI”), compared to either AO or MI performed in isolation. These results indicate the potentially beneficial effects of AO+MI, and they also demonstrate that the underlying neurocognitive processes are partly shared. We separately review the evidence for MI and AO as forms of motor simulation, and present two quantitative literature analyses that indeed indicate rather little overlap between the two bodies of research. We then propose a spectrum of concurrent AO+MI states, from congruent AO+MI where the contents of AO and MI widely overlap, over coordinative AO+MI, where observed and imagined action are different but can be coordinated with each other, to cases of conflicting AO+MI. We believe that an integrative account of AO and MI is theoretically attractive, that it should generate novel experimental approaches, and that it can also stimulate a wide range of applications in sport, occupational therapy, and neurorehabilitation
Agronomic characteristics and post-harvest longevity of ornamental sunflower inflorescences
No full textNos últimos anos a demanda por girassol ornamental de corte tem aumentado mas, ainda são poucas as informações disponíveis sobre o cultivo e pós-colheita de suas inflorescências, cuja longevidade é variável e dependente do cultivar. Dessa forma, o objetivo do trabalho foi avaliar características fitotécnicas de três cultivares de girassol ornamental e a eficiência de utilização de soluções conservantes na longevidade e qualidade de hastes florais de girassol ornamental. Utilizaram-se os cultivares Sunbright, Sunbright Supreme e Vincents Choice para realização dos experimentos. O primeiro experimento, realizado em delineamento em blocos casualizados, consistiu da avaliação das características fitotécnicas dos três cultivares de girassol. O segundo experimento, realizado em delineamento inteiramente casualizado, consistiu da avaliação das soluções de sacarose (0, 3, 6, 9 e 12%) na longevidade pós-colheita dos três cultivares. O terceiro experimento, realizado em delineamento inteiramente casualizado, consistiu em avaliar a eficiência de soluções conservantes (Controle, Flower® 2 mL L -1 , Crystal Clear® 10 g L -1 , Sulfato de Alumínio 0,5 g L -1 , Ácido giberélico (GA 3 ) 20 mg L -1 e Hipoclorito de sódio 100 mg L -1 ) na longevidade pós-colheita dos cultivares, utilizando-se uma escala de senescência para girassol ornamental. Menor ciclo de cultivo (53 dias) e maiores diâmetros da haste (1,3 cm) e inflorescência (13 cm) foram observados no cv. Vincents Choice. Já o Sunbright apresentou maiores produções de massas fresca e seca. As doses de sacarose não foram eficientes em aumentar a longevidade pós-colheita dos três cultivares de girassol ornamental. O cultivar S. Supreme mostrou a maior longevidade pós-colheita (15,9 dias), seguido do Sunbright (14,35 dias) e V. Choice (11,8 dias). As soluções conservantes afetaram significativamente a longevidade das hastes florais do V. Choice com incremento de 3,5 dias na longevidade pós-colheita das hastes submetidas à solução de GA 3 . Houve incremento de 2,5 dias na vida pós-colheita das hastes florais do cv. Sunbright submetidas ao hipoclorito de sódio em relação à testemunha. As soluções de GA 3 , hipoclorito de sódio e sulfato de alumínio se mostraram como eficientes alternativas às soluções comerciais para os cultivares estudados. Os cultivares utilizados mostraram características fitotécnicas adequadas para a utilização como flor cortada. O GA 3 em solução conservante mostrou potencial para utilização no V. Choice cultivar.In recent years the demand for cut ornamental sunflower has increased but little information is available on the cultivation and post harvesting of its inflorescences, whose longevity is variable and dependent on the cultivar. Thus, the objective of this work was to evaluate agronomic characteristics of three ornamental sunflower cultivars and the efficiency of the use of preservative solutions on the longevity of ornamental sunflower flower stems. Sunbright, Sunbright Supreme and Vincents Choice hybrids were used for the experiments. The first experiment realized in randomized block design, consisted of the evaluation of agronomic characteristics of the three sunflower cultivars. The second experiment realized in completely randomized design, consisted of using different sucrose concentrations (0, 3, 6, 9 and 12%) to evaluate their effect on the postharvest longevity of the three cultivars. The third experiment realized in completely randomized design, consisted in evaluating different preservative solutions (Control, Flower® 2 mL L -1 , Crystal Clear® 10 g L -1 , Aluminum Sulphate 0.5 g L -1 , Gibberellic Acid (GA 3 ) 20 mg L -1 and Sodium Hypochlorite 100 mg L -1 ) on postharvest longevity of cultivars, using a ornamental sunflower senescence scale. The lowest cultivation cycle (53 days) and larger stem (12.8 mm) and inflorescence (13 cm) diameters were observed on V. Choice cultivar. Sunbright presented higher fresh and dry mass production. Sucrose doses were not efficient at increasing the postharvest longevity of the three ornamental sunflower cultivars. S. Supreme cultivar showed the highest postharvest longevity (15.9 days), followed by Sunbright (14.35 days) and V. Choice (11.8 days). Preservative solutions significantly affected longevity of V. Choice floral stems with a 3.5-day-increment in postharvest longevity with GA 3 solution. There was an increase of 2.5 days in postharvest life of Sunbright cultivar submitted to Sodium Hypochlorite compared to the control. Solutions of GA 3 , Sodium Hypochlorite and Aluminum Sulphate proved to be efficient alternative to commercial solutions for the cultivars tested. Cultivars used showed adequate agronomic characteristics for using as a cut flower. GA 3 in pulsing solution showed potential for using in V. Choice cultivar.Conselho Nacional de Desenvolvimento Científico e Tecnológic
Genetic diversity of macauba from natural populations of Brazil.
Get PDFThe macauba has been identified as the most promising native species for the production of vegetable oil and biomass. Several studies confirm its potential for numerous purposes (liquid and solid biofuels, food, cosmetics and pharmaceuticals), but this Brazilian biodiversity resource has been little explored, and work aimed at their domestication and genetic improvement are relatively recent. This study consisted of a multivariate approach to levels of trans fatty acids, oil yield and physical characteristics found in fruits of macauba of natural populations. The objective was to quantify the genetic variability among 35 genotypes of natural populations of macauba from 16 locations in different regions of Brazil. Euclidean Distance measurements were estimated and the cluster analysis obtained by the UPGMA method considering separately the fatty acid profile, and traits related to physical part and the fruits oil content
