Abstract: One of the most important steps in the improvement of food products quality, in the last 40 years, is represented by food fortification with minerals and essential vitamins, a way to correct a deficiency, to balance the nutritional profile or to restore nutrients lost in the processing. In this context, this work aimed at mineral determination in gluten-free almond or peanut cookies, to verify their potential as a source of essential nutrients. The quantification of iron, magnesium, calcium, copper, zinc, potassium and sodium was carried out via flame atomic absorption spectroscopy and phosphorus was quantified via UV-VIS-spectrophotometry. The data showed that the cookies developed with almond could be considered, for adults, a source of copper and iron and rich in phosphorus and that the ones elaborated with peanuts could be considered rich in phosphorous, magnesium and iron. Both cookies could be considered sources of copper, magnesium, phosphorous and iron, when values are directed to the consumption of children from 4 to 6 years old, showing nutritional potential to celiacs. KEY-WORDS: Celiac disease; cookies; minerals; iron.

Abstract: A Acrocomia aculeata (Jacq.) Lodd. Ex Mart. popularmente conhecida como macauba ou bocaiuva, é uma palmeira encontrada em quase todo território brasileiro. Seu fruto pode ser consumido tanto na forma in natura quanto na forma processada de farinha. O presente trabalho teve como objetivos caracterizar a farinha de bocaiuva (FB), bem como estudar a utiliza o desta no desenvolvimento de biscoitos tipo cookie avaliando sua composi o centesimal e características sensoriais. Foram elaboradas seis formula es de biscoito onde a FB substituiu a farinha de trigo nos níveis de 10% e 15%. A FB mostrou-se uma excelente fonte de calorias, rica em lipídios, fibras, carboidratos e vitamina A. A substitui o da farinha por 15% de FB nas formula es, resultou em biscoitos classificados como alimentos fontes de fibras (3,46 a 3,88 g fibras em 100 g de produto). O conteúdo de vitamina A dos biscoitos adicionados de FB variou de 13,20 a 23,40 RAE/100g. Os resultados obtidos na avalia o sensorial demonstraram que os biscoitos formulados com diferentes níveis de FB foram bem aceitos pelos julgadores.

Abstract: hovenia dulcis, whose popular name is japanese grape, belongs to the family rhamnaceae, native of china, japan and korea, is widely distributed in southern brazil. rich in sugar and with good acceptance for human consumption it can be consumed fresh or processed. there are no literature reports of its use in food products. the aim of this study was to determine the chemical composition of the japanese grape fruit, concentrated extract and flour. the contents for moisture (54.08, 52.44 e 19.08g 100g-1), ash (2.16, 4.09 e 4.48g 100g-1), protein (3.74, 2.77 e 5.73g 100g-1), ethereal extract (1.42, 0.37 e 1.82g 100g-1), dietary fiber (12.56, 3.33 and 25.62g 100g-1) and total sugars (19.46, 37.34 and 42.53g 100g-1) were obtained for the fruit, concentrated extract and flour, respectively. quantification by liquid chromatography confirmed that the content of reducing sugars (fructose, 6.15g 100g-1 and glucose, 6.57g 100g-1) is higher than the non-reducing sugars content in fruit (sucrose, 3.56g 100g-1). calories resulted in values of 105.56, 165.14 and 216.09kcal 100g-1 for fruit, concentrated extract and flour, respectively. the flour is rich in sugars and has a high content of dietary fiber being able to be used as an alternative ingredient in bakery products. sensory analysis of the concentrated extract revealed an acceptability rate of 82% among the judges, showing good potential for jams' production.
Beyond the Clash between World-Views: Revisiting Husserl’s Concept of the Life-World  [PDF]

Advances in Anthropology (AA) , 2013, DOI: 10.4236/aa.2013.33023

Husserl shares the European view whereby (physical and psychic) nature is the common denominator upon which the diversity of cultures are built, a vision that motivates the quest for the conditions of possibility of encounters beyond cultural differences, truth beyond multiple perspectives, and moral reconciliation beyond antagonisms. The American-Indian worldview seems to challenge that view, for it rather proposes a multinaturalism built upon a type of human and spiritual community common to every cosmic being. Husserl’s notion of the “life-world” is revisited, whereby what appears at first sight as “in-compossible” world-views shows indeed traits of an amazing proximity.

Horizontal transmission of HIV infection in an HIV-exposed child—An avoidable tragedy  [PDF]

Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.26097
Abstract: Exposure to infected blood/blood products through blood transfusion and use of contaminated sharp objects remain an important source of HIV infection. This report describes the case of a 52-month-old male child of an HIV-infected mother in whom perinatal infection was successfully prevented by maternal and infant antiretroviral therapy, elective cesarean section, and avoidance of breast-feeding. A DNA PCR test at 6 weeks was negative and a rapid antibody test at 18 months was seronegative. He presented to the Paediatric infectious disease unit with chronic fever, cough, diarrhea and weight loss 7 months after receiving a commercially donated blood (in a rural private hospital) and scarification marks (by a traditional healer) for a febrile illness with convulsion. He was found to be seropositive with severe immunosuppression. He however died a month after being initiated on antiretroviral drug.

Abstract: The overall purpose of the study was to explore the relationship between various family-related factors and crime. The study also attempted to ascertain whether those factors can act as causative agents for “juvenile delinquency”. The study postulated that although there are different factors that impact on the development of child character, the family plays a central role in child development and consequentially impacting on the character of a child. In order to critically analyze the hypothesis of study, the paper reviewed the concepts of juvenile delinquency and family. Although the paper centered on the family factors influencing delinquency, it equally attached premium on the non-family factors influencing levels of juvenile delinquency. The study found out that there are several notable family-related factors that impact on child crime. These include parental attitudes, the degree of family cohesion, physical violence, and uninvolved parenting. There are also non-family factors that impact on juvenile delinquency, which include the failure of the juvenile justice system, poverty, a lack of access to education, drug abuse and genetic problems.
Evolution, Strategies and Problems of Poverty-Alleviating Agricultural Policies and Programmes in Nigeria  [PDF]

Abstract: According to the UNDP (2001) report, Nigeria started its independent nationhood in 1960 with poverty level of only 15% of population, but it is today struggling to reduce it from about 70% of its current population of about 190 million. This is in spite of the fact that the country is richly endowed with numerous natural, especially agricultural and mineral resources. Nigeria’s rising extreme poverty numbers are a direct result of years of negligent and ineffective government policies. Over-dependence on oil for years and an inability to generate non-oil revenue has led it to this. The country’s agricultural policy aims at reaching self-sustaining growth in the agricultural sector as well as the structural transformation required for the overall socio-economic development and improvement in the quality of life of Nigerians. The key feature of the policy is the evolution of strategies for ensuring self-sufficiency and the improvement of the technical and economic efficiency in food production. This is to be achieved through the introduction and adoption of improved seeds and seed stock, husbandry and appropriate machinery and equipment, efficient utilization of resources, encouragement of ecological specialization and recognition of the roles and potentials of small-scale farmers as the main drivers of food production in the country. Nigeria’s agricultural policy framework has evolved in a way that reflected, in a historical perspective, the changing character of agricultural development problems and the roles which different segments of the society were expected to play in addressing these problems. The form and direction of agricultural policy were dictated by the philosophical stance of government on the content of agricultural development and the role of government in the development process. Here, we examined Nigeria’s agricultural policy evolution from the colonial to the contemporary period. The very survival of Nigeria is tied to the ability of its economy to meet the material demands of its citizens since welfare constitutes a third objective of modern government. Food is an essential component of welfarism. The Nigerian Government and public policy makers must therefore see food as a component of welfarism and as such develop and sustain sufficient political will to achieve increased food production, a credible food policy and ultimately degrade poverty significantly.
