Efeito das condições climáticas do semiárido sobre o comportamento fisiológico de caprinos mestiços f1 saanen x boer

This research aimed at evaluating the effect of the semiarid climatic conditions on the physiological behavior of F1 Saanen x Boer crossbred goats, created at an intensive system. The experiment was carried out in the Health and Rural Technology Center, in the Federal University of Campina Grande, in the town of Patos, Paraiba. Twenty-four animals were used, with ages varying between three and four months, being 12 females and 12 males, weaned and prevented against worms, receiving ad libitum water and controlled concentrate and roughage. The environmental variables were checked inside and outside the experiment place, as well as the physiological variables of all animals. Except for the humid bulb temperature, the variance analysis revealed shift effect (P<0.05) for all environmental variables. There was merely shift effect (P<0.05) for Cardiac Frequency and Rectal Temperature, and the averages of both, in the afternoon, overcame those observed in the morning. The obtained results based on the studied physiological and environmental variables conclude that crossbred goats, resulting of Boer (paternal) and Saanen (maternal), present a good resistance to heat, permitting their indication for the meat production in confinement on semiarid conditions.

Knowledge Representation and Orthophemism: A Reflection Aiming to a Concept

Characteristics of speech, especially figures of speech, are used by specific communities or domains, and, in this way, reflect their identities through their choice of vocabulary. This topic should be an object of study in the context of knowledge representation once it deals with different contexts of production of documents. This study aims to explore the dimensions of the concepts of euphemism, dysphemism, and orthophemism, focusing on the latter with the goal of extracting a concept which can be included in discussions about subject analysis and indexing. Euphemism is used as an alternative to a non-preferred expression or as an alternative to an offensive attribution-to avoid potential offense taken by the listener or by other persons, for instance, pass away. Dysphemism, on the other hand, is used by speakers to talk about people and things that frustrate and annoy them-their choice of language indicates disapproval and the topic is therefore denigrated, humiliated, or degraded, for instance, kick the bucket. While euphemism tries to make something sound better, dysphemism tries to make something sound worse. Orthophemism (Allan and Burridge 2006) is also used as an alternative to expressions, but it is a preferred, formal, and direct language of expression when representing an object or a situation, for instance, die. This paper suggests that the comprehension and use of such concepts could support the following issues: possible contributions from linguistics and terminology to subject analysis as demonstrated by Talamo et al. (1992); decrease of polysemy and ambiguity of terms used to represent certain topics of documents; and construction and evaluation of indexing languages. The concept of orthophemism can also serves to support associative relationships in the context of subject analysis, indexing, and even information retrieval related to more specific requests.

Evaluation of the components of production of the ricinus according of rates of calcareous rock and match

The soil of the Paraiba, in generality, are acid and with low levels of available match, seriously limiting the income of the plants. A research in vegetation house was lead, with the objective to evaluate doses of calcareous soil and match in the culture of ricinus. The treatments had been composites for five levels of match: 0.0; 80; 160; 240 and 360 kg ha(-1) of P(2)O(5) and four dosis of calcareous rock: 0.0; 2.5; 3.5 and 4.5 t ha(-1) in experimental delineation of blocks casualized with 4 factorial project x 3 (four levels of match and three doses of calcareous soil) more two treatments you add zero of match (0.0 P(2)O(5): 2,5 t ha(-1) of calcareous soil) and calcareous soil zero (240 P(2)O(5): 0.0 t ha(-1) of calcareous soil), with three repetitions. The calcareous soil reduced the acidity of the ground and effect of the application of the match (>= 80 kg ha(-1) of P(2)O(5)) in the presence of the collagen (>= 2.5 t ha(-1) of CaCO(3)) with of the calcareous soil (>= 2.5 t ha(-1) of CaCO(3)) in the presence of the match was not verified well (>= 80 kg ha(-1) of P(2)O(5)). The match applied in the absence of the calcareous soil was limited to the income of the culture of what the calcareous soil in the absence of the match.

Utilização de polímero hidroabsorvente no meloeiro (Cucumis melon L.) sob diferentes lâminas de irrigação

This work was carried out to evaluate the use of a hydrogel polymer in melon crop under different irrigation depths, with the objective of improve water retention, and efficiency of water and nutrient utilization by plants. One trial consisted of two treatments with four replications: a treatment with irrigation depth corresponding to 75% of gross depth and 27g of the soil conditioner per plant; the control with irrigation depth equal to the gross depth and without conditioner. The following characteristics were evaluated: root length, yield and quality of melon fruits. Root growth was bigger in the plants where soil conditioner was used. Use of soil conditioner provided an increase on melon yield and number of fruits per linear meter. Mean fruit weight and total soluble solids were not influenced by soil conditioner application and irrigation depth reduction.

As diferentes “personalidades” do número racional trabalhadas através da resolução de problemas

We address the different "personalities" of the rational number and the concept of proportionality, analyzing the possibilities for using the Mathematics Teaching and Learning through Problem-solving Method. This method is based on the principle that knowledge can be constructed through the use of problems that generate new concepts and new contents. The different meanings of rational number - rational point, quotient, fraction, ratio, and operator - are constructs that depend on mathematical theories in which they are imbedded and the situations that evoke them in problem-solving. Some data will be presented from continuing education courses for teachers, aiming to contribute to understanding regarding the different "personalities" of the rational number. In general, these "personalities" are not easily identified by teachers and students, which is the reason for the many difficulties encountered during problem-solving involving rational numbers. One of these "personalities", the ratio, provides the basis for the concept of proportionality, which is relevant because it is a unifying idea in mathematics.
