Beef aging is a process that involves the interaction of enzymes and chemical transformations that directly influence changes in flavor and texture, which in turn can determine the sensory experience for guests. The purpose of this study was to compare, in terms of texture, the aging of beef brisket cuts through two techniques: with animal fat coating and dry aging, over a period of 21 days, and to determine the acceptability of end consumers. The cuts were stored under controlled temperature and moisture conditions (2 °C and 60 % relative moisture, respectively), with continuous monitoring to ensure food safety. Finally, they were cut into 2 cm thick steaks, fried to medium doneness with salt, and sensorially evaluated by a panel of 27 individuals. The results revealed an acceptance rate of 74.1 % for the meat sample aged with animal fat, surpassing the dry-aged sample (22.3 %) and the...

The writing of a screenplay for an animated film for children is a delicate process due to several factors: the nature of a script, whose goal is not only to be written, but must also be produced to fulfill its purpose; the high costs of audiovisual production, which oblige it to include commercial values in its poetics to guarantee a recovery of the large investment; the demands of a highly segmented public, such as children; and the demands of a society that expects high commercial values from cultural industries. In this sense, the main goal of this article is to propose a characterization of children’s animation cinema based on three axes: the commercial (in order to meet the audience’s requirements), the authorial (in order to respect the author’s poetics) and the hybrid (which balances both interests). To achieve this, a theoretical framework oriented to mass culture based on...

This paper deals with teacher training. Discusses some definitions on this process and also have their particular characteristics, emphasizing one: to be an ongoing activity. The authors argue that teacher training is one of the best indicators to assess the improvement of education and that it also plays an important role in building the identity of teachers. They argue that the professional development plan must be animated by an emancipatory interest, in support of a change of mentality, personality, into the role of teacher as a freelancer and not one that reproduces the given. In a second step, is analyzed the process of initial training, it is this crucial stage in the training of teachers. It lays the foundation for the necessary and required personality as teaching that the teacher must necessarily acquire. Are described three orientations of initial training: the academic or per...

The study focuses on the use of husks of plant origin for the production of silage for livestock. Four vegetable peels stand out: cassava, potato, passion fruit, and banana, each with beneficial properties for fattening and optimal growth of animals. Traditional silage methods, which involve machinery and emit polluting gases, contrast with the proposal to use domestic plant waste, thus reducing the carbon footprint. In addition to improving livestock food security, this approach provides additional income to households, enhancing quality of life. The study collected vegetable peels and established four treatments (T1, T2, T3, and T4). Physicochemical parameters were measured throughout the ensiling process, demonstrating that lactic acid was produced in all treatments since the initial pH 6.5 decreased to 5.5 in the first week and 4.5 in the second week. Likewise, it was shown that trea...

The Toxocara canis parasite represents a worldwide public health problem. This agent is an ascarid that, in its adult stage, lives in the small intestine of the domestic dog and several wild canids; it presents a complex biological cycle that ensures its transmission and permanence in the hosts it affects; in its intestinal phase, it causes mechanical, irritative and obstructive action, interfering in the transit and digestion of food. Toxocariasis affects young dogs and cats; it produces respiratory signs (cough due to migration of pulmonary larvae), growth retardation (emaciation, weakening of the coat and arthralgia) and intestinal disorders (alternating diarrhea and constipation, abdominal bulging, and vomiting). More intense prenatal infections in puppies can lead to severe disease with alternating diarrhea and constipation, vomiting, typical "pot belly," reduced growth with cachexi...
