title: Yield, berry quality and physiological response of grapevine to foliar humic acid application

description: ABSTRACT Environmentally friendly grape growing is an important objective of modern viticulture. The aim of the study was to examine the response of two grapevine Vitis vinifera L. cultivars to humic acids (HA) foliar application as biostimulant in order to provide sustainable viticultural practices for farmers. The experiment was carried out under field conditions and repeated in two consecutive years. In order to evaluate the effect of humic acids application, the grapevines were treated with three concentrations: 30 ml.L-1 (HAT1), 40 ml∙L-1 (HAT2) and 50 ml∙L-1 (HAT3). The grapevines were represented by two grape varieties: cv. Feteasca Regala (cv. FR) and cv. Riesling Italian (cv. RI). Foliar sprays with humic acid derived from vermicompost at a concentration of 50 ml∙L-1 induced a significant increase in the total leaf area, yield and total soluble solids. For several measurements performed in plants we found no significant difference between grapevines treated with HAT2 and those with HAT3. The experimental results in the present study confirm that foliar application with humic acid may improve growth, yield, and berry quality attributes of grapevine.

title: Elaboration and validation of diagrammatic scale for lettuce powdery mildew

description: ABSTRACT Powdery mildew, caused by Oidium sp., is a disease of great importance in hydroponic crops of lettuce. However, in Brazil, there is scarce research focused on the epidemiological study of this disease, as standardized methods are necessary to quantify the disease severity in hydroponic systems. Thus, a logarithmic scale was developed at levels of 0.37, 1, 2, 4, 8, 16, 32 and 74% injured leaf area, testing the parameters accuracy and precision. The proposed scale was validated by eight evaluators, of whom four were experienced and four were inexperienced, and they used 50 leaves showing symptoms of the disease at different severity levels, previously measured with the aid of QUANT® software. Two evaluations were performed with a 48-h interval, in which the evaluators visually estimated distinct sequences of leaves. Linear regression was used to determine the accuracy and the precision of each evaluator. The proposed scale showed satisfactory results of accuracy and precision, and despite the inexperience of four evaluators, absolute errors were in the range of 8% after training. The proposed scale was adequate to estimate the severity of powdery mildew on lettuce.

title: Engagement among Health Science Undergraduate Students (Validation of the Ultrecht Work Engagement Scale (UWES-S) with Health Science Undergraduate Students)

description: ABSTRACT Entry into academic life brings about significant changes in one's life, and these changes are linked to the teaching-learning model and the student's routine. Engagement is considered the opposite of Burnout, and unlike students who suffer from academic stress, engaged students feel very connected to the activities, perceiving them as positive challenges. This research had the general objective of evaluating the Engagement Score among Health Science undergraduate students; and, the specific objectives of validating the Utrecht Work Engagement Scale (UWES-S) instrument with Health Science undergraduate students; to evaluate vigor, dedication and absorption of the Engagement construct, as well as to compare scores between variables of two or more categories to obtain the Engagement Score among Health Science undergraduate students. Method: Cross-sectional analytical observational study with a quantitative approach. Results: The UWES-S was validated when applied to undergraduate students of five Health Science programs, in levels of vigor, dedication and absorption. Regarding the Dimensions Score, medicine and nursing students presented greater vigor and dedication; part-time morning class and full-time students show greater vigor and absorption; in the Absorption dimension, a higher score was observed among students up to the fourth semester of the course. As for the time dedicated to study outside university, the observed scores remained high in all three dimensions of the construct, as well as for students who practiced leisure activities. Part-time morning and full-time medical and nursing students who were married and have children, who spend much of their time studying outside university and maintain leisure activities, show a higher Engagement Score in relation to academic demands. Conclusion: Engagement is a recent construct to be applied to Brazil. Furthering our understanding of this construct enabled us to gain a new perspective of the academic setting, the students’ mechanisms to adapt to higher education and the need for the teacher to be within reach as a mediator and the university to act in support of this process.

title: Prevalence of upper respiratory diseases and associated factors in Colombian Creole horses

description: ABSTRACT To determine the prevalence of diseases of the upper respiratory tract and associated factors in the Colombian Creole Horse Valley Aburrá in 2015, a random sampling of 15 farms in southern Aburrá Valley under different management conditions was performed. A total of 105 CCC underwent general clinical examination, respiratory endoscopic evaluation and a detailed inspection of housing conditions and management. A low prevalence of upper respiratory tract diseases was observed, including Pharyngeal Lymphoid Hyperplasia 38.1%, Recurrent Laryngeal Neurophaty 12.38%, Dorsal Displacement of the Soft Palate 7.62%, and presence of tracheal secretions not associated with a specific pathology. A bivariate analysis showed association between tracheal secretions and frequency of training per week (OR = 9.86), duration of the training sessions (OR = 5.55) and inadequate ventilation of the stable (OR = 10.52). Association between HLR and inadequately ventilated barns was also observed (OR = 14.9). Logistic regression showed association between tracheal secretions and inadequate ventilation (OR = 7.18). We conclude that inadequate ventilation was the most important factor for the incidence of upper respiratory tract diseases in horses at the southern area of the Aburrá Valley.

title: Impact of malocclusion on the quality of life of children aged 8 to 10 years

description: ABSTRACT Objective: The aim of the present cross-sectional study was to assess the impact of malocclusion on the quality of life of children aged 8 to 10 years attending public elementary schools in Belo Horizonte, State of Minas Gerais, Brazil. Methods: The Brazilian version of the Child Perceptions Questionnaire 8-10 (CPQ8-10) was used to evaluate oral health-related quality of life. The children were examined for the diagnosis of malocclusion using the Dental Aesthetic Index (DAI). The data were analyzed by bivariate and multivariate descriptive statistics using Poisson regression at a 5% significance level. A total of 270 children participated in the study. Results: Children with normal occlusion or mild malocclusion (DAI ≤ 25) were 56% less likely (95%CI: 0.258-0.758; p= 0.003) to have their quality of life affected compared with children diagnosed with extremely severe malocclusion (DAI ≥ 36). Children with a maxillary anterior overjet ≥ 3 mm had higher CPQ8-10 mean scores (19.4; SD = 17.1) than those with an overjet &lt; 3 mm (13.6; SD = 11.7; p= 0.038). Conclusions: Extremely severe malocclusion and pronounced maxillary anterior overjet were associated with a negative impact on quality of life.

title: Thought Styles in the Choice of Medical Specialty and their Correlation with Primary Care Provision Policies - A Case Study

description: ABSTRACT With the publication of the National Curriculum Guidelines for medical schools, in 2001, changes were implemented in medical courses with the aim of meeting the needs of the Unified Health System in terms of Primary Health Care training. One of the biggest difficulties found in the setting of Primary Health Care was that the staff was lacking both in numbers and quality of the professionals. In this context, the qualitative goal of this research was to identify the features surrounding the choice of medical specialty among graduates from UNIVALI who had effectively participated in Primary Health Care projects during their undergraduate studies. The data was collected by means of semi-structured interviews and the data analysis performed using the Thought Style category, developed by Ludwik Fleck. The results revealed the hegemony of a Thought Style with characteristics aimed at the focal expertise and with a market-oriented outlook on the profession, yet with an expanded view to addressing problem, and was therefore called the Extended Flexnerian Thought Style. In a counter-hegemonic way, another Thought Style was identified that focuses on comprehensive general practice, with an eminently public appeal, here entitled the Primary Health Care Thought Style. The hegemony of the Flexnerian Thought Style was especially justified by the force of neoliberal links, and supported by the predominantly Flexnerian curriculum structure. The complications experienced by some of the interviewees working in Primary Health Care were also considered major obstacles that hinder the consolidation of a Primary Health Care Thought Style and, consequently, the choice to work in that particular field. Inter-group movements was also show to be an important factor in the process of choosing a medical specialty, yet still under ordered according to the links. In spite of these choices, a closer approach to Primary Health Care proved to be very important in building the counter-hegemony forming the expanded view of the classic Flexnerian Thought Style, which are both important for changing the heath care model.

title: Ultrasonographic aspects of umbilical components of Holstein calves during the physiological involution process

description: ABSTRACT Umbilical diseases of calves happen during neonatal period and may lead to severe complications. The diagnosis is usually through abdominal palpation although it is not very accurate, thus ultrasound provides a valuable complementary exam to establish a precise diagnosis of location and extent of intra-abdominal umbilical diseases. Given those facts and the lack of established standards for umbilical ultrasound imaging the present study proposal was to standardize the physiological aspects of umbilical components during involution. Ultrasound images were obtained for 23 Holstein calves, from birth until 30 days of life. Iodine tincture of different concentrations was used for umbilical region antisepsis. Results show that umbilical vein and arteries lose their vessel characteristics, becoming similar to ligament, due to the proliferation of fibrous tissue. The growth pattern of the fibrous tissue was from the vessel walls growing toward vascular lumen. The involution process begins at the most distant part and did not vary with antiseptic concentrations. To obtain a reliable ultrasound exam it’s important to know the aspects of imaging patterns according to each phase of umbilical involution, thus leading to an accurate diagnosis of structural variations and umbilical diseases.

title: Rasterizing Chromatograms

description: This report describes an application of the ‘rasterize’ package for R. We rasterize (just) the line segments of two chromatograms in order to render one semi-transparently over the other. This also demonstrates, more generally, the value of having access to advanced graphical techniques within statistical graphics software.
