title: Behavior of buffalo heifers reared in shaded and unshaded pastures during the dry season on Marajó Island, Pará, Brazil

description: ABSTRACT. The objective of this research was to evaluate the behavior of twenty buffalo heifers reared during the dry season on Marajó Island, Pará, Brazil. The animals were distributed into two groups, those with shade (WS) and those without shade (WOS). The experimental day was divided into six shifts: morning (6:00 to 9:55 a.m.), intermediate (10:00 a.m. to 1:55 p.m.), afternoon (2:00 to 5:55 p.m.), evening (6:00 to 9:55 p.m.), night (10:00 p.m. to 1:55 a.m.), and early morning (2:00 to 5:55 a.m.). The WS group was kept in silvipastoral system paddocks, while the WOS group was kept in unshaded paddocks. Climatic data were registered and temperature and humidity index (THI) were calculated. Behavior data such as grazing, rumination, idle time, and other activities (walking, defecating, mounting, drinking water, urinating, eating salt) were evaluated. The results showed that the THI was higher in the WOS group. Grazing time was higher in the WOS group than in the WS group in the intermediate shift (p &lt; 0.05), while in the afternoon, evening, and early morning shifts, the WS group spent more time grazing than the WOS group. In the intermediate and early morning shifts, the WS group spent more time ruminating (p &lt; 0.05); the WS group ruminated more than the WOS group. The WOS group had more idle time, especially in the evening and early morning shifts (p &lt; 0.05), while the WS group had more idle time in the intermediate shift (p &lt; 0.05). We conclude that buffaloes graze and ruminate more intensely when they are reared in a shaded system on the island of Marajó.

title: Characterization of the interactions between chitosan/whey protein at different conditions

description: Abstract This research investigated the interaction between chitosan and whey protein molecules in terms of pH and heating. The FTIR, rheological analysis, turbidity, and zeta potential measurements were used to assess this interaction. At pH 4.0, addition of low amount chitosan with chitosan/whey protein isolate (C/WPI) ratio of 1:5 effectively prevented the denaturation of whey proteins after heating, whereas high amount of chitosan (C/WPI,1:2) led to depletion flocculation. The combination of chitosan and whey proteins was electrostatic attracting at pH 5.5 and 6.0. At low chitosan addition, the complexes formed at pH 5.5 showed higher viscosity and the complexes formed at pH 6.0 showed a shear-thinning behaviour. At high chitosan addition, the complexes showed high viscosity at pH 6.0. Heating led to the decrease of viscosity and increase of turbidity. The results manifested that chitosan and whey protein formed different complexes at pH 5.5 and 6.0, and the complexation of C/WPI was influenced by heating and ratio of chitosan and whey proteins.

title: Hearing disorders - findings on computed tomography and magnetic resonance imaging: pictorial essay

description: Abstract Hearing disorders are usually unilateral and are more common in women. They can be congenital or acquired, and hearing loss is categorized as sensorineural, conductive, or mixed. The onset of hearing loss can be progressive or sudden, and it is a common reason for seeking medical attention. In this context, computed tomography and magnetic resonance imaging have assumed critical roles in the search for an etiological diagnosis and in guiding the therapeutic approach. In this pictorial essay, we illustrate the common causes of hearing loss, discussing the possible differential diagnoses and highlighting the most relevant imaging findings.

title: The effect of saleps obtained from various Orchidacease species on some physical and sensory properties of ice cream

description: Abstract The study was aimed to investigate the effect of different salep properties on ice cream quality parameters. Therefore, salep samples obtained from six different Orchidaceae spp. were examined for glucomannan and starch contents. Statistically significant differences were observed between the glucomannan and starch levels, viscosity values (between 23.90 cP and 430.90 cP), and overrun levels (between % 32.62 and % 42.46) of ice cream mixes and melting qualities of ice cream samples according to species of the salep sample (p &lt; 0.05). It is concluded that high-glucomannan (&gt; 40%) containing salep samples, which were obtained from the species (O. mascula ssp. pinetorum, S. vomeracea ssp. vomeracea) have significantly desired effects on the viscosity values and overrun levels and contributes to the sensory qualities of Kahramanmaras type ice cream. Abundant production of good quality salep depends on the cultivation of high-glucomannan species in particular.

title: Influencing factors of consumer willingness to buy cattle meat: An analysis of survey data from three Brazilian cities

description: ABSTRACT. Brazil is currently undergoing a process to establish new patterns of consumption habits and the implementation of a new concepts of meat quality. The process emphasizes the quality of information delivered to consumers, which is part of the new approach to meat quality and food safety. The objective of this article is to investigate the attributes considered important when buying beef, knowledge about the production process, labelling, cuts and characteristics of the animals. The study included 276 consumers in three Brazilian cities and their responses were examined in relation to the semi-structured form with fifteen spontaneous and stimulated questions. It was verified that the presentation of the product is regarded as the most important attribute at the time of purchase, they prefer to purchase meat in the butchers, and do not value the labelling of the product, which makes it difficult to identify and offer differentiated products or certificates. The frequency of consumption of beef increases with family income and the vast majority of consumers prefer low marbling meat regardless of the type of preparation. The consumer has little knowledge of more specialized cuts, since the product sold in the butchers has different cuts terminology.

title: USE OF PROTECTION SCREEN IN CONVENTIONAL AVIARIES (CALIFORNIAN TYPE) FOR LAYING HENS

description: ABSTRACT The objective of this work was to evaluate the thermal environment inside conventional cages for laying hens, with and without the use of protective screens. This research was conducted in two conventional cages (open cage), where each cage had half of its area surrounded by high density polyethylene mesh (HDPE) with a diameter of 2.0 cm, and the other half was kept fully open. Hyline W-36 and Dekalb Brown laying hens were housed in these cages. The wind speed, dry bulb temperature (tdb), black globe temperature, humidity index (BGHI), and enthalpy (H) were analyzed. The results indicate that the use of the screen reduced the wind speed inside the cage by 0.22 m s−1. The presence of the screen affected tdb, BGHI, and H in some of the evaluated periods evaluated, making these values higher than those of the treatment without screen. However, the obtained values are within or below the thermal comfort range for laying birds. Therefore, the use of HDPE screen in the cages altered their internal environment. However, it is not enough to hinder the thermal comfort of the housed animals.

title: Breeding goals and economic values for Nellore cattle in a full-cycle production system

description: ABSTRACT. The objective of this study was to develop a bio-economic model for the estimation of economic values of economically important traits in a full-cycle beef cattle production system. The bio-economic model calculated economic values by simulating the impact of changes in the profit of the system consisting of a 1% increase in each trait of the breeding objective, while the other traits were kept constant. The bio-economic model was effective in estimating the sources of revenues and expenses of the production system. The estimated economic values were, in the order of importance for the full-cycle system, R$ 3.69 for male slaughter weight, R$ 3.63 for male weaning weight, R$ 3.58 for weaning rate, R$ 3.40 for female slaughter weight, R$ 2.30 for female weaning weight, and R$ 0.13 for mature cow weight. The results showed that all traits evaluated in the full-cycle system had positive economic impact, indicating that selection would increase profitability maximizing the expected response for the traits of the breeding goal.

title: Musculoskeletal "don't touch" lesions: pictorial essay

description: Abstract Focal bone lesions are not uncommon findings in the daily practice of radiology. Therefore, it is essential to differentiate between lesions with aggressive, malignant potential that require action and those that have no clinical significance, many of which are variants or benign lesions, sometimes self-limited and related to reactive processes. In some cases, a diagnostic error can have catastrophic results. For example, a biopsy performed in a patient with myositis ossificans can lead to an incorrect diagnosis of sarcomatous lesions and consequently to mutilating surgical procedures. The present study reviews the main radiological aspects of the lesions that are most commonly seen in daily practice and have the potential to be confused with aggressive, malignant bone processes. We also illustrate these entities by presenting cases seen at our institution.

title: ESTIMATION OF THE CHARACTERISTIC VALUE OF WOOD STRENGTH

description: ABSTRACT For safety reasons, wood strength values, essential for structural dimensioning, are calculated based on the characteristic value, which corresponds to the 5% percentile of a given probability distribution model. For small samples, the Brazilian normative document ABNT NBR 7190 establishes an estimator of the characteristic wood strength, which can provide a significantly different result from the characteristic value coming from a suitable model of probability distribution. The main objective of this study was to evaluate the best probability distribution model (normal, lognormal, Weibull, and exponential) and the subsequent calculation of the characteristic value indicated by ABNT NBR 7190 (1997), allowing to evaluate its accuracy, being also investigated two relationships between characteristic values of the simplified characterization condition for woods of species already known. The best adhesion model was the normal model, which resulted in values statistically equivalent to the characteristic values according to ABNT NBR 7190 (1997). Among the evaluated relationships, the obtained results were significantly higher (up to 92%) when compared to those estimated by ABNT NBR 7190 (1997).

title: Magnetic resonance imaging of the breast: role in the evaluation of ductal carcinoma in situ

description: Abstract Ductal carcinoma in situ (DCIS) is a precursor mammary lesion whose malignant cells do not extend beyond the basement membrane and presents a risk of progression to malignant disease. Its early detection increased with screening mammography. The objective of this study was to review the literature on the main presentations of DCIS on magnetic resonance imaging (MRI), through searches of the Medline/PubMed, Latin-American and Caribbean Center on Health Sciences Information (Lilacs), and Scientific Electronic Library Online (SciELO) databases. DCIS can occur in its pure form or in conjunction with invasive disease, in the same lesion, in different foci, or in the contralateral breast. MRI has a high sensitivity for the detection of pure DCIS, being able to identify the non-calcified component, and its accuracy increases with the nuclear grade of the lesion. The most common pattern of presentation is non-nodular enhancement; heterogeneous internal structures; a kinetic curve showing washout or plateau enhancement; segmental distribution; and restricted diffusion. MRI plays an important role in the detection of DCIS, especially in the evaluation of its extent, contributing to more reliable surgical excision and reducing local recurrence.

title: BETWEEN TYPES AND RADICALS: THE CONSTRUCTION OF THE CONCEPT OF VALENCE

description: This paper presents a historical case study regarding the development of the concept of valence in late nineteenth and early twentieth centuries. The case study focuses on Edward Frankland’s contribution to the process which lead to the convergence of two theories about the combination of the elements: the theory of types and the theory of radicals. Results show how such process involved many other scientists from various countries and how the concept of valence related to studies on bonding, periodicity and chemical structure. Changes in the nomenclature and notation were also observed. In the beginning of the twentieth century, the empirical concept of valence received theoretical explanations under the light of the then new theories on electronic structure of atoms. Thus, this case study exemplifies the complexity of the process of development of a scientific concept and, in particular, shows the multiplicity of connections of the concept of valence in the body of chemical knowledge.
