Criação de empresas à luz do modelo de decisão effectuation: um estudo com mulheres empreendedoras no município de Currais Novos/RN

This study analysed the creation of businesses by entrepreneur women in the Currais Novos city, looking for verifying if they used making decision processes aligned to the Effectuation logic throughout the creation of their companies. To this, was accomplished a multiple cases and exploratory study, whit a qualitative approach of analyse, using the thematic life history technique that match accounts and semi-structured interview route, being accomplished like a long interview, where the researcher interact with the informer continuously. The semi-structured interview route was created by the adaptation of the interview route used by Tasic (2007). The present study appealed to a intentional selection of individuals in function of their importance in relation to the boarded theme. This means that the individuals were chosen in function of their social and theoretical representatively inside the considered situation. The participant individuals of this research were five entrepreneur women that act in the Currais Novos city, owners of five different companies. To the data treatment and analyse, was chosen the content analyse technique. This study worked with a priori theoretical categories. The categories of analyse in this study was obtained with base in the Effectuation approach (SARASVATHY, 2001a, 2001b, 2008), that is an alternative model of making decision to the classic model based in the causality principle. These categories are Clarity of Initial Aims , Tolerance to the Lost and Initials Investments , Control of Resources ( who I am , what I know and who I know ) and Promoting Over Contingencies . As result, the entrepreneur women researched, in a general way, hadn t clear initial aims at the companies creation moment, hadn t aversion to the risk to lose the time and the money that they were investing in the company in formation, they highlighted the products and services identity that offered with a strong link with Seridó region, they had experience in the field of activity in which they decided to open their companies, had the commitment of partners in the beginning of the business and they knew to transform the initial difficulties in opportunities. By the end, this study conclude that the entrepreneur women studied used, in a big part, making decision processes aligned to the Effectuation logic throughout the creation of their companies

Sistema não-Intrusivo para Estimação da Direção do olhar utilizando redes neurais artificiais

The fundamental senses of the human body are: vision, hearing, touch, taste and smell. These senses are the functions that provide our relationship with the environment. The vision serves as a sensory receptor responsible for obtaining information from the outside world that will be sent to the brain. The gaze reflects its attention, intention and interest. Therefore, the estimation of gaze direction, using computer tools, provides a promising alternative to improve the capacity of human-computer interaction, mainly with respect to those people who suffer from motor deficiencies. Thus, the objective of this work is to present a non-intrusive system that basically uses a personal computer and a low cost webcam, combined with the use of digital image processing techniques, Wavelets transforms and pattern recognition, such as artificial neural network models, resulting in a complete system that performs since the image acquisition (including face detection and eye tracking) to the estimation of gaze direction. The obtained results show the feasibility of the proposed system, as well as several feature advantages.

Práticas agroecológicas para o cultivo do gergelim (Sesamum indicum L.)

The exceeded use of the natural resources required by the modern agriculture has been caused soil impoverishment, soil salinization and soil compaction. The unreasonable use of chemical fertilizers and pesticides causes chemical imbalances in the plant tissues, nutritional losses, taste chances and human health problems. The monocrops are more vulnerable to the pest and disease attacks. The aim of this work were to indicate the better relative planting time of the cowpea bean for the sesame/cowpea bean intercropping based on the evaluation of agronomic, economic, ecological and physiological parameters and to evaluate the viability of the cow urine and cassava wastewater use as alternative fertilizers on the sesame cultivation. In a field essay, when the sesame/cowpea bean was evaluate, the mainly treatments were the single planting of the two cultures and the multiple cropping, with the cowpea bean being planted on the same time, 7, 14 and 21 days after the sesame. The mainly treatments of the second essay were the combined doses of the cow urine (0 and 50 ml) and cassava wastewater (0, 500 and 1000 mL). In the intercrop evaluation significant differences were found between the treatments for the most of the parameters. It was verified that as the sowing of the cowpea bean was retarded in relation to the sesame sowing, the sesame performance increased when the cowpea bean performance decreased. The treatment 7 days balanced the competition relations that occurred between the two crops in the intercrop. The sesame presented little pronounced responses to the different doses of cassava wastewater. The cow urine affected the sesame growth and the growth rates increased with the increasing of the application of the product. The responses of the sesame growth to the cow urine application must be related both the nutritional richness of the product and the presence of growth stimulating substances. The obtained results indicated that in the sesame/cowpea bean intercropping, when the sesame is planted 7 days after the sesame, there is a higher possibility of the net gains to the farmer. Cow urine and cassava wastewater may be used as additional organic fertilizers

Características sensoriais da carne de cordeiros das raças Hampshire Down, Santa Inês e Mestiços Bergamácia x Corriedale abatidos com quatro distintos pesos

Cordeiros das raças Hampshire Down (20), Santa Inês (24) e mestiços Bergamácia x Corriedale (36), abatidos com 4 distintos pesos: (28, 32, 36 e 40 kg), foram comparados quanto aos caracteres sensoriais da carne. Os animais, desmamados aos 60 dias de idade, foram encaminhados para terminação em confinamento total, onde recebiam dieta composta por 35% de feno e 65% de concentrado. Após o abate e resfriamento da carcaça, foi extraído o músculo longissimus dorsi para efeito de realização das provas sensoriais. Não se constatou efeito de peso ao abate sobre os caracteres sensoriais avaliados. Na carne dos cordeiros mestiços detectou-se maior valor ao sabor do que a apresentada pela raça Santa Inês, igualando à raça Hampshire Down. Quanto à maciez, ajustada para peso de abate, os cordeiros mestiços exibiram valores superiores em relação às duas raças puras. Para as demais características, os três genótipos se assemelharam. de maneira geral, os resultados experimentais mostraram alta qualidade sensorial.

Características sensoriais de carne defumada de capivara

O presente trabalho teve como objetivo desenvolver alguns produtos, como paleta e copa defumadas, em escala de laboratório, com a carne de capivara (Hydrochoerus hydrochaeris), e empregar a técnica de maturação da carne por meio da utilização de cloreto de cálcio. Inicialmente procedeu-se a verificação da composição centesimal na carne in natura, e posteriormente realizou-se a avaliação sensorial e a determinação da composição centesimal dos produtos obtidos pelos seguintes tratamentos: Tratamento A - paleta defumada, submetida à maturação inicial com cloreto de cálcio; Tratamento B - paleta defumada sem a maturação inicial; Tratamento C - copa defumada, submetida à maturação inicial com cloreto de cálcio e; Tratamento D - copa defumada sem a maturação inicial. A carne in natura de capivara apresentou composição média de 76,59% de umidade, 0,90% de resíduo mineral fixo, 20,04% de proteína e 0,91% de extrato etéreo. Os produtos elaborados apresentaram, em média: 67,72% de umidade, 2,16% de resíduo mineral fixo, 24,93% de proteína e 2,77% de extrato etéreo. Os produtos defumados de carne de capivara não apresentam diferenças quanto ao aroma, sabor, aroma estranho e sabor estranho. A paleta defumada apresenta-se mais macia e suculenta do que a copa defumada. A utilização de cloreto de cálcio cinco horas após o abate não tem efeitos significativos nos atributos sensoriais.

Unilateral Facial Paralysis Caused by Ramsay Hunt Syndrome

The Ramsay Hunt syndrome is a rare disease caused by an infection of the geniculate ganglion by the varicella-zoster virus. The main clinical features of the syndrome are as follows: Bell palsy unilateral or bilateral, vesicular eruptions on the ears, ear pain, dizziness, preauricular swelling, tingling, tearing, loss of taste sensation, and nystagmus. We describe a 23-year-old white woman, who presented with facial paralysis on the left side of the face, pain, fever, ear pain, and swelling in the neck and auricular region on the left side. She received appropriate treatment with acyclovir, vitamin B complex, and CMP nucleus. After 30 days after presentation, the patient did not show any signs or symptoms of the syndrome. At follow-up at 1 year, she showed no relapse of the syndrome.

Ingestion of hypertonic NaCl vs. palatable drinks by sodium-depleted rats

This work investigated whether the preference for NaCl solution is shifted to more palatable solutions in the adult male sodium-depleted rat (n=6-10 per group). Animals had daily access to three bottles, one containing water, another 1.8% NaCl (300 mM), and a third containing 0.9% NaCl (150 mM), Gatorade (orange-OG or grape flavored-GG), orange juice (sweetened or unsweetened, from concentrate), or 10% sucrose (no sodium). Sodium content in Gatorade and orange juice ranged from 7 to 14 mEq/l. Daily intakes were recorded for at least 5 days prior to sodium depletion. Then, the animals were depleted of sodium (diuretic plus sodium-deficient diet and water for 24 h). Then, the other two bottles were returned to the animals and the intakes were recorded for 120 min (sodium preference test, SPT). Daily intake from the third bottle (except for unsweetened orange juice) at least doubled the daily 1.8% NaCl intake. The average 1.8% NaCl intake (13 +/- 2 ml) in the SPT was higher than the intake of 10% sucrose (6 +/- 1 ml) or of any other solution (less than 6 ml). The intakes of 1.8% NaCl and 0.9% NaCl (10 +/- 3 ml) were similar during the SPT. The animals also preferred 0.9% NaCl (27 +/- 1 ml) to OG (3 +/- 1 ml) in the absence of 1.8% NaCl in the SPT. Therefore, the preference for sodium in sodium-depleted rats also applies when palatable and nutritive solutions are simultaneously available. (C) 2002 Elsevier B.V. All rights reserved.

Higher salt preference in heart failure patients

Heart failure (HF) is a complex syndrome that involves changes in behavioral, neural and endocrine regulatory systems. Dietary salt restriction along with pharmacotherapy is considered an essential component in the effective management of symptomatic HF patients. However, it is well recognized that HF patients typically have great difficulty in restricting sodium intake. We hypothesized that under HF altered activity in systems that normally function to regulate body fluid and cardiovascular homeostasis could produce an increased preference for the taste of salt. Therefore, this study was conducted to evaluate the perceived palatability (defined as salt preference) of food with different concentrations of added salt in compensated chronically medicated HF patients and comparable control subjects. Healthy volunteers (n = 25) and medicated, clinically stable HF patients (n = 38, NYHA functional class II or III) were interviewed and given an evaluation to assess their preferences for different amounts of saltiness. Three salt concentrations (0.58, 0.82, and 1.16 g/100 g) of bean soup were presented to the subjects. Salt preference for each concentration was quantified using an adjective scale (unpleasant, fair or delicious). Healthy volunteers preferred the soup with medium salt concentration (p = 0.042), HF patients disliked the low concentration (p < 0.001) and preferred the high concentration of salted bean soup (p < 0.001). When compared to healthy volunteers, HF patients demonstrated a significantly greater preference for the soup with a high salt concentration (p = 0.038). It is concluded that medicated, compensated patients under chronic treatment for HF have an increased preference for salt. (C) 2011 Elsevier Ltd. All rights reserved,

Antioxidantes utilizados em óleos, gorduras e alimentos gordurosos

Lipid oxidation is certainly one of the most important alterations that affect both oils or fats and foods that contain them. It is responsible for the development of unpleasant taste and smell in foods, making them unsuitable for consuming. The use of antioxidants permits a longer useful life of these products. This work presents a bibliographic review of research carried out in order to evaluate the antioxidant activity of natural or synthetic substances used in the conservation of food lipid. Among such substances, the following antioxidants are highlighted: butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), tertiary butylhydroquinone (TBHQ), propyl gallate (PG), tocopherols, phenolic acids and isolated compounds from rosemary and oregano.
