The objective of this investigation was to evaluate the weight and percentage of the non-carcass components and the mineral content (macro minerals and trace minerals), crude protein, ether extract, moisture and vitamin E of the heart, liver, tongue, lungs, reticulum, kidneys and meat from the longissimus dorsi of lambs in feedlot finishing. Thirty-two non-castrated Ile de France male lambs, fed diets containing sunflower seeds and vitamin E from 15 to 32 kg of body weight were allotted in a completely randomized design in a 2 × 2 factorial arrangement. The weight of the gastrointestinal tract was higher in the lambs fed diets containing vitamin E (10%). No difference was observed in the liver as to the mineral matter, crude protein, ether extract, moisture (2.01; 20.03; 2.39 and 74.78 g/100 g, respectively), the macro minerals and trace minerals, except iron. In the tongue, lungs, reticulum, kidneys and meat there was no in fluence of diets in the studied variables. The liver and the meat presented different values of crude protein (20.01 and 18.34 g/100 g, respectively), and the heart (1.03 mg/100 g) showed a higher content of vitamin E. High contents of manganese, zinc and copper were observed in the liver. The evaluated non-carcass components were nutritionally equal to the sheep meat, once, in addition to their high yield in relation to the body weight at slaughter, the non-carcass components are sources of nutrients.

OBJETIVO: Avaliação preliminar na Clínica Oftalmológica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (USP) de equipamento inovador para baixa visão desenvolvido na USP que consiste em prancha de leitura acoplada a lente de aumento que mantém fixos o foco e a linha de leitura. MÉTODOS: Foram avaliados 9 pacientes com visão subnormal usando o supracitado equipamento prancha de leitura acoplada a lente para auxílio em visão subnormal desenvolvida na USP em comparação com uso de uma lupa teste manual de dioptria semelhante, considerando-se os seguintes parâmetros de avaliação: causa da doença, acuidade visual corrigida no melhor olho para longe, impressão pessoal do paciente comparando prancha de leitura e lupa teste, impressão dos autores observando o uso dos 2 auxílios acima citados. RESULTADOS: A preferência pelos recursos foi: prancha de leitura acoplada a lupa - 5 pacientes; lupa manual - 2 pacientes; sem preferência por nenhum dos recursos - 1 paciente; inadequados para avaliação dos recursos preferidos - 1 paciente. CONCLUSÃO: Neste estudo preliminar, a maioria dos pacientes avaliados preferiu o recurso prancha de leitura acoplada à lupa, o que mostra que este produto inovador facilita a leitura; o médico avaliador interpreta a opinião do paciente como um especialista e contribui para o aprimoramento do produto para que ele possa ser futuramente submetido a novas avaliações.

ABSTRACT PURPOSE: To perform a preliminary evaluation at the "Clínica Oftalmológica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (USP)" of an innovative equipment for low-vision developed at USP containing a reading stand and a magnifier that maintains in a stable position the reading line and focus. METHODS: 9 low-vision patients were evaluated using the above mentioned reading stand and a magnifier developed at USP comparing it with a hand magnifier of similar power taking into account the following evaluation parameters: etiology of low-vision, best corrected visual acuity for distance, patient's opinion comparing both low-vision aid resources, authors' opinion observing the patient using both low-vision aids. RESULTS: The numerical preference for the low-vision aids was: 5 patients for the reading stand and a magnifier that maintains at a stable position the reading line and focus; 2 patients for the hand magnifier; 1 patient indifferent regarding any of the resources; 1 patient inadequate for the evaluation of the low-vision aids. CONCLUSION: This preliminary study shows the preference of the majority of the patients for the reading stand and a magnifier that maintains at a stable position the reading line and focus showing that this innovative product makes reading easier; the evaluator doctor translates the patient's opinion as an expert and contributes to the improvement of the product so that it can be evaluated again in the future.

Agile software processes emerged to address the issue of building software on time and within the planned budget. To adopt an agile process, it is imperative to analyze and evaluate its effectiveness in supporting high quality software development while complying with stringent time constraints. In this paper we describe an agile method for Web-based application development (XWebProcess) and an experiment conducted with a group of forty senior undergraduate students to assess the quality/speed effectiveness of the proposed method vis-à-vis the effectiveness of Extreme Programming (XP). The results have shown that the process proposed is equally agile when compared to XP, moreover, surveys conducted as part of the experiment pointed out that XWebProcess is more suitable to Web development in dimensions such as requirements gathering, user interface and navigation design, and software testing, therefore leading to better quality software.
