The use of accelerometers to classify and predict animal behavior can be a tool for continuous animal monitoring. Therefore, the aim of this study was to provide strategies for predicting more and less frequent beef cattle grazing behaviors. The behavior activities observed were grazing, ruminating, idle, water consumption frequency (WCF), feeding (supplementation) and walking. Three Machine Learning algorithms: Random Forest (RF), Support Vector Machine (SVM) and Naïve Bayes Classifier (NBC) and two resample methods: under and over-sampling, were tested. Overall accuracy was higher for RF models trained with the over-sampled dataset. The greatest sensitivity (0.808) for the less frequent behavior (WCF) was observed in the RF algorithm trained with the under-sampled data. The SVM models only performed efficiently when classifying the most frequent behavior (idle). The...

So far, studies have mainly focused on the effects of these micronutrients on animal performance, but their use in a rumen-protected form and their impact on liver metabolism in finishing beef cattle is poorly known. We used a shotgun proteomic approach combined with biological network analyses to assess the effects of a rumen-protected B-vitamin blend, as well as those of hydroxy trace minerals, on the hepatic proteome. A total of 20 non-castrated Nellore males with 353 ± 43 kg of initial body weight were randomly assigned to one of the following treatments: CTRL—inorganic trace minerals without supplementation of a protected vitamin B blend, or SUP—supplementation of hydroxy trace minerals and a protected vitamin B blend. All animals were fed the same amount of the experimental diet for 106 days, and live...

Despite the current knowledge of the effects of vitamin B complex and trace minerals on animal performance, their use as a rumen-protected form and its impact on liver metabolism in finishing beef cattle is poorly known. The present study aimed to assess the effects of ruminally protected B-vitamin blend (Trouw Nutrition, Italy) and hydroxy trace minerals (Cu and Zn; Micronutrients Inc., Indianapolis, IN) on hepatic proteome. A total of 20 non-castrated Nellore males with 353 ± 43 kg of initial BW were submitted in a high supplementation (1.7% of BW) in pasture and randomly assigned to one of the following treatments: CTRL – inorganic trace minerals without supplementation of vitamin B blend; SUP – supplementation of hydroxy trace minerals (Cu and Zn) and vitamin B blend (B5, B6, B7, B9, and ...

These maps were obtained by means of the analytic hierarchy process (AHP), using six information levels: the height above the nearest drainage (HAND) model, the declivity map, three lineament maps (morphostructural, radiometric and magnetometric), and the lithological map. The E–W strike of the lineaments was emphasized for the integration, because it is the most frequent and subparallel to the present strike of the maximum principal stress σ1. The favorability maps were validated by varying the input parameters and comparing the maps with 82 specific capacity values obtained from well tests. Although more data should be necessary to confirm this method, the results are promising and can be tested in other crystalline basement areas.

The experiment was carried out in a double Latin (4x4) experimental design with eight animals, consisting of four periods and four experimental rations. Eight lambs with no defined racial pattern were used, with mean initial body weight (BW) of 23.74 ± 1.00 kg. The ingestive behavior was performed during 24 hours, always on the last day of each experimental period. The physiological variables and the environmental variables were measured during three days of each period. Data were submitted for analysis of variance and, when significant, regression equation was applied at 5% of probability. Statistical analysis was performed considering the subdivision of the plot, which consisted of the diurnal and nocturnal evaluation times for the ingestive behavior and the morning ...

It analyzed patients who suffered from Hansen's disease based on social-demographic data, clinic form and time of disease evolution. It identified ocular alterations, relating clinic form to the time of evolution of this illness. The sample was composed of a group 60 patients: 39 were men and 21 were women, 35 were tan, 19 were white and 6 were black. The examination of these patients included eye-lid muscular power, external structures, ocular mobility, cornea sensitiveness, tear production, field and visual accuracy. The clinic form was dimorphous (42); virchovian (13); undefined (3) and tuberculoid (2). Disease evolution was from 1 to 4 years in 42 of the patients. Regarding eye alterations there was a reduction of tear production (32); of eye-lid muscular power (12) and of cornea sensitiveness (10); hyperemia (13); lagophthalmos (8) and madarosis (7), mainly concentrated in the dimorphous form (43) and virchovian (15).

Electron microscopy showed the tonofilament-desmosome complex to be preserved in the various layers of the epidermis. Immunoglobulin was bound over the plasma membrane and permeated the desmosomal junctions both in the skin and oral mucosa, thus suggesting that pemphigus antibodies arc attached to the glycocalyx. It appears that the initial injury in SAPF acantholysis involves the glycocalyx and that it might be caused by interaction with intercellular antibodies present in the patient's serum. South American pemphigus foliaceus (SAPF), or Togo sclvagem' (wild fire), is a disease endemic in Brazil, but also reported in Northern Argentina, Paraguay, Venezuela and Peru, and which difTers from Cazenave pemphigus foliaceus in its course and epidemiology (Brown, 1954; Proen^a & Castro, 1971). The purpose of this paper is to report a combined transmission electron microscopy study and immunoelectron localization of bound immunoglobulin in the skin and oral mucosa in SAPF in an attempt to understand the pathogenesis of the lesions. PATIENTS AND METHODS Five patients with generalized SAPF were examined. The average age was 31-8 years. Three of them

The genomic sequencing of C. violaceum ATCC 12472 has revealed many genes that underpin its adaptability to diverse ecosystems. Moreover, C. violaceum genes with potential applications in industry, medicine and agriculture have also been identified, such as those encoding chitinases. However, none of the chitinase genes of the ATCC 12472 strain have been subjected to experimental validation. Chitinases (EC 3.2.1.14) hydrolyze the β-(1,4) linkages in chitin, an abundant biopolymer found in arthropods, mollusks and fungi. These enzymes are of great biotechnological interest as potential biocontrol agents against pests and pathogens. This work aimed to experimentally validate one of the chitinases from C. violaceum. Results The open reading frame (ORF) CV2935 of C. violaceum ATCC 12472 encodes a protein (439 residues) that is composed of a signal peptide, a chitin-binding ...

The wood (juvenile) came from thinning a 15–18-year-old plantation located in Mato Grosso state, Midwest Brazil, broken down into plainsawn battens measuring 25 × 70 × 1 070 mm (radial × tangential × longitudinal). The battens were from material close to the pith which was combined heartwood (≈75%) and sapwood. We sampled untreated and thermally modified battens, which were transformed into specimens for testing. The thermal modification was carried out at 160 °C in an industrial scale reactor, according to the parameters of the TanWood process, which is classified as a closed hygrothermal system. Twelve specimens by treatment (25 × 60 × 50 mm3 — radial × tangential × longitudinal) were conditioned in a climatic chamber set up at 35 °C and the relative humidity (RH) was raised stepwise (31%, 49%, 69...
