SummarySelenium is an important mineral required in the antioxidant system in animals, which is involved with oxidative stability in tissues, particularly membranes, and is involved in various aspects of meat quality and stability on the shelf, due to its protective properties on lipids, preventing rancidity. Se can be supplied in an inorganic or chemically organic form, and it is well known that the latter has beneficial properties and improved functionality in physiological systems compared to the former. Research has shown that organic Se is associated with increased tenderness and the prevention of certain problems in pale exudative meat, discolouration and off-flavours and odours in meat, although this depends on other components of the antioxidant system, such as vitamin E, being present as well. The change in prominence of glutathione peroxidase forms in their interaction with vitamin E in cell membranes is also noted. The following review (the third in a series) details the research that has been conducted into the role of Se in meat stability and related factors, with specific focus on organic forms of Se, namely the commercial product Sel-Plex™ (Alltech Inc, Nicholasville, KY, USA), which is derived from yeast and in which selenium replaces sulphur in methionine forming selenomethionine in yeast protein.

SummaryThe storage and cooking quality of meat is dictated by the ability of muscle cells to effectively hold water. If this ability is diminished, then presentation at time of purchase is poorer, as the packaging fills with watery exudates (termed ‘drip loss’), which is detrimental to sales. In addition, these losses affect cooking and eating sensory qualities. It is known that antioxidants play a major role in ensuring robustness of the cell membrane in muscle, and within this, selenium (Se) plays a major part, being an essential component within an antioxidant enzyme system and its interaction with vitamin E within membranes. The following review examines the body of evidence for Se as an antioxidant to preserve water holding capacity, especially with reference to using a chemically organic form of the mineral which is akin to those forms found in natural feed materials.

The aim of the trial was to determine the efficacy of organic Se from Se-enriched yeast in placental transfer to piglets in the conditions of a Czech pig farm. In group I (n = 8) the sows were fed during gestation and lactation a diet supplemented with inorganic Se (sodium selenite, 0.3 mg/kg of Se for the gestation and 0.38 mg/kg of Se for the lactation diet). In group II (n = 8) the diet of the sows was supplemented with organic Se from Se-enriched yeast (0.3 mg/kg of Se for the gestation and 0.38 mg/kg of Se for the lactation diet). Se concentrations in the whole blood, colostrum and milk were higher (P < 0.01) in the group of sows fed with the organic Se form. No differences in GSH-Px activities in the whole blood were found between the two groups of sows. The concentrations of Se in piglet tissues (heart P < 0.05, liver P > 0.01, muscle P > 0.01) were also higher when the organic form was provided. It is concluded that the use of the organic Se from Se-enriched yeast in sows resulted in greater transfer of Se to their progeny, however it did not have a positive effect on the antioxidant system of the organism.

This article sheds light on the role of grammar in understanding legislative texts, with reference to the wuḍūʾ verse (Q. 5:6). The first section deals with the issue of washing the elbows along with the feet as part of ritual ablution, and lists the various interpretations of the preposition ilā in the aya, and discusses the grammatical theory used by different fuqahāʾ to support their arguments. The second section tackles how much of the head should be rubbed in ritual ablution, with regard to the use of the preposition bi- in the phrase bi-ruʾūsikum, while the third focuses on the two readings of the phrase arjulakum/arjulikum (‘your feet’) and on passing legislative judgement on whether the feet be washed or just rubbed. The study concludes that lugha and fiqh theory are of mutual importance and together help to clarify legislative judgements, and, on this basis, that jurists should not pass any legislative judgement without referring to language.

The objectives of this qualitative research were (1) to identify the factors that affect the Minangkabau language (ML) maintenance in Medan, (2) to discover the parents’ efforts in maintaining ML in Medan and (3) to find out the reason why the speakers have to maintain ML. The souree of data is the nembers of the Association of Sei Jaring Community (Ikatan Warga Sei Jaring: IWS) in Medan. The sample was 10 families including 10 parents and their children. The instruments of this study are a questionnaire and an interview. The questionnaire was used to answer the factors affected the maintenance of ML and how factors affected the maintenance of ML. The interview was used to discover the influence why Minangkabau’s people have to maintain ML. There are four factors in ML maintenance, the parents’ role, the role of family, the intramarriage and homeland visits. After distributing questionnaire and did some interviews it is found that IWS especially for the third generation (children) has the danger level in ML when they communicate to each other. Meanwhile, the data analysis also shows that both fathers and mothers communicate to each other with ML. This condition occurred because of the influence of the environment. Parents have to keep communication and teaching Minangkabau language continuously to their children. so, the young generation can keep the existence of ML for their future. Keywords: Minangkabau Language Maintenance, parents’ efforts, the young generation.

Zakat is an important form of religiously mandated charity under Islam. It is the third pillar of Islam. The giving of Zakat is important for Muslims, as this leads to purification of their wealth from all sins. This paper examines the role of Zakat as an instrument of social justice and poverty eradication in society. Each Muslim calculates his or her own Zakat individually. Generally, this involves the payment each year of two and a half percent of one's capital, after the needs of the family have been met. One can donate additional amount as an act of voluntary charity but Zakat is fundamental to every Muslim. Zakat is the Islamic contribution to social justice: those who have to give charity share the benefit of their prosperity to those who have fallen short. This is the Islamic approach to remove greed and envy and to purify one's soul based on good intentions. This is the institution of Zakat in Islam. The institution of Zakat serves to eradicate poverty in the community and uphold the light of Islam. Allah says “whatever is paid as Zakat for the sake of Allah shall be rewarded in manifolds”.

Resumo:  Apresenta-se uma discussão sobre o conhecimento e a tese dos três mundos no qual a interação entre estes nos aproxima da verdade do problema corpo-mente, tendo em vista, uma nova proposta de solução. O terceiro mundo é uma peça importante neste trabalho; sendo assim, analisaremos o que Popper designa como Mundo 3, em que ele consiste e o papel da linguagem como diferencial do ser humano. Apresentamos as críticas popperianas às correntes monistas e dualistas, ousando fazer uma crítica a Teoria do Conhecimento tradicional. Desta forma, a proposta apresentada por este filósofo da ciência diferencia-se de tudo que estava sendo feito até então, por isso, o interesse de apresentar essa abordagem pouco trabalhada de Popper. Palavras-chave: Conhecimento. Corpo-Mente. Mundo 3.Abstract: In this work, we present a discussion about knowledge and the theory of the three worlds in which the interaction between them approaches to the truth of the mind-body problem, in view of a proposed solution. The third world is an important piece in this work. Therefore, we will analyze what Popper describes as World 3, what it is and the role of language as a differential of human beings. We present Popper’s criticisms to the monistic and dualistic currents, daring to criticize the theory of traditional knowledge. Thus, the proposal of science presented by this philosopher differs from everything that was being done until then. This explains the interest in presenting this unusual approach to Popper.Keywords: Knowledge. Body-Mind.  World 3. REFERÊNCIASLEAL-TOLEDO, Gustavo . Popper e seu Cérebro.
