title: Economic and climatic models for estimating coffee supply

description: Abstract: The objective of this work was to estimate the coffee supply by calibrating statistical models with economic and climatic variables for the main producing regions of the state of São Paulo, Brazil. The regions were Batatais, Caconde, Cássia dos Coqueiros, Cristais Paulista, Espírito Santo do Pinhal, Marília, Mococa, and Osvaldo Cruz. Data on coffee supply, economic variables (rural credit, rural agricultural credit, and production value), and climatic variables (air temperature, rainfall, potential evapotranspiration, water deficit, and water surplus) for each region, during the period from 2000-2014, were used. The models were calibrated using multiple linear regression, and all possible combinations were tested for selecting the variables. Coffee supply was the dependent variable, and the other ones were considered independent. The accuracy and precision of the models were assessed by the mean absolute percentage error and the adjusted coefficient of determination, respectively. The variables that most affect coffee supply are production value and air temperature. Coffee supply can be estimated with multiple linear regressions using economic and climatic variables. The most accurate models are those calibrated to estimate coffee supply for the regions of Cássia dos Coqueiros and Osvaldo Cruz.

title: Dynamic Response and Microstructure Evolution of Oxygen-Free High-Conductivity Copper Liner in Explosively Formed Projectile

description: Abstract The dynamic response and microstructure evolution of oxygen-free high-conductivity copper in a shaped charge liner are investigated through microstructural examination of a soft-recovery EFP. Adiabatic shear bands and voids which is the failure original of copper EFP can be observed in the rear part of the projectile. Numerical simulation results illustrate that the highest plastic strain reaches about 2.9 which can fully accommodate the grains deformation of copper EFP during the formation process at strain rates of the order of 104s−1. Theoretical calculation results indicate that the highest temperature increase of EFP caused by shock wave and plastic deformation can reach 747K, which is 0.55T m (where T m is the melting temperature of copper). The main body of the EFP undergoes completely dynamic recrystallisation, and the average size of the refined grains significantly decreases to approximately 10µm. A slight increase in grain size occurs mainly away from the center and extends towards the head and rear sections of the EFP. During the DRX process, the dislocation movement is believed to be the controlling mechanism significantly refining the microstructure.

title: Dual Task Multimodal Physical Training in Alzheimer’s Disease: Effect on Cognitive Functions and Muscle Strength

description: Abstract The aim of this study was to evaluate the effects of dual task multimodal physical training (MPT) on the cognitive functions and muscle strength in older adults with AD. Participants were 19 subjects with AD in the mild and moderate stages, divided into training group (TG) and control group (CG). The TG performed dual task MPT for 12 weeks. Subjects were evaluated at the pre- and post-intervention moments. The Mini Mental State Examination (MMSE), Clock Drawing Test (CDT) and Frontal Assessment Battery (FAB) were used to assess cognition. For muscle strength, the Chair Lift and Sit Test (CLST) and Manual Grasp Force (MGF) were used. The Wilcoxon test was used to analyze pre and post intragroup moments. The TG showed a significant improvement in FAB and CLST (p≤0.05) and a tendency to improve the MMSE score (p≤0.08). The CG showed significant improvement in CLST (p≤0.05). Dual task MPT improves the frontal cognitive functions and lower limb muscle strength of older adults with AD.

title: Pain and palliative care: the knowledge of medical students and the graduation gaps

description: ABSTRACT BACKGROUND AND OBJECTIVES: Currently, the medical course does not provide complete education and handling of pain, and it is also devoid of disciplines addressing thanatology in palliative care. The objective of this study was to evaluate the knowledge about pain and palliative care of medical students and their perception on how these themes are taught the graduation course. METHODS: We invited to participate in the survey students of the medical school who are concluding the fourth, fifth and sixth year of graduation at the Federal University of Health Science of Porto Alegre. The demographic and characterization data of the sample were collected, and a questionnaire was applied and validated with 19 direct questions about pain and palliative care. RESULTS: Forty-seven students agreed to participate in the study. The vast majority mentioned not receiving enough information during the undergraduate program about the proper handling of patients with pain, and patient care in a terminal situation. CONCLUSION: This study highlights education gaps on pain and palliative care in medical schools. It shows the difficulties of the students have to put the theoretical knowledge into practice, for example, their insecurity in handling pain, especially when it comes to the use of opioids.

title: Effect of a physiotherapy program in patient with persistent polyarthralgia after chikungunya fever. Case report

description: ABSTRACT BACKGROUND AND OBJECTIVES: Chikungunya fever is caused by the chikungunya virus, but with characteristics similar to the dengue fever. The main clinical manifestation that differs from dengue is the strong joint pains, which can remain for long periods, and that is found at lower intensity and duration with dengue. The objective of this study was to contribute to the physical therapy in patients with persistent polyarthralgia after chikungunya fever. CASE REPORT: Female patient, 35 years old, diagnosed with persistent polyarthralgia after chikungunya fever. When admitted to the physiotherapy service, she complained of severe pain in the knee, wrist and right ankle, mainly in the morning. For the physiotherapeutic evaluation, the following parameters were used: visual analog scale, use of painkillers, goniometry, modified sphygmomanometer test, and perimetry. The functional assessment was done through a 10m walking test, Quick Dash and Lequesne scales, Portuguese version, for the upper and lower limbs, respectively. The proposed physiotherapeutic program was based on therapeutic exercises and manual therapy for 4 weeks. The results showed that the proposed physical therapy was effective in decreasing the pain, increasing muscle strength, the range of motion, decreasing edema and improving functional capacity. CONCLUSION: The physiotherapeutic treatment proved to be effective in treating a patient with persistent polyarthralgia after chikungunya fever, improving the subjective pain and functional capacity.

title: Football coaches’ development in Brazil: a focus on the content of learning

description: Abstract AIM The aim of the study was to analyze the lifelong content of learning of coaches. METHODS Eight coaches inserted in an Elite Football Club participated. Rappaport Time Line and semi-structured interviews were used to obtain the data. The coaches’ learning was organized according to the theory of Lifelong Learning.1-4 RESULTS The coaches presented in their personal experiences, with their families and as athletes, content of learning such as “leadership development” and “formation of values”. In professional experiences, such as in academic training, coach assistants and even coaching, they are also reported as essential in obtaining content of learning (general and specific knowledge, training methods, leadership development, self-control). Finally, the reflexive process is considered by most coaches as a potentiator of learning, with interference on the “coach-athlete relationship”, “activity adjustment,” among other content of learning. CONCLUSION The content learned throughout the life were defined in certain episodes for presenting different meanings in the life of the coaches, in which they related to a new experience according to their biographies. Therefore, the various episodes offer coaches new experiences, in which they can incorporate, reinforce or renew the content about the coaching process and are responsible for the development of the coach.

title: In vitro conservation of blackberry genotypes under minimal growth conditions and subsequent large-scale micropropagation

description: Abstract: The objective of this work was to evaluate the micropropagation of blackberry (Rubus spp.) cultivars, after in vitro conservation under minimal growth conditions. Nodal segments of the 'Guarani', 'Caingangue', 'Ébano', and 'Xavante' genotypes were conserved under minimal growth conditions at 20ºC, for 15 months. Microshoots were regenerated and multiplied by up to five successive subcultures, when they were rooted and acclimatized. After 30 days of acclimatization in a greenhouse, rooted plantlets showed no significant losses. Blackberry cultivars can be conserved in vitro for 15 months, without subcultures and, after this time, they can be micropropagated on a large-scale, maintaining the regenerative potential and multiplication.

title: Chemical characterization and oxidative stability of olive oils extracted from olive trees of Southern Brazil

description: Abstract: The objective of this work was to characterize the chemical composition of olive (Olea europaea) oils produced in Southern of Brazil and correlate it with oxidative stability. Olive oils from the Arbequina, Coratina, Frantoio and Koroneiki cultivars were evaluated. A completely randomized experimental design was used, in a uniform arrangement, with three replicates. Acidity value, peroxide index, specific absorption, tocopherol content, phenolic compound content, carotenoid content, chlorophyll content, fatty acid profile, and oxidative stability were determined. The oils from the Coratina and Frantoio cultivars were classified as extra virgin-oils. The olive oil from the Coratina cultivar showed the highest levels of pigments, followed by the oil from Koroneiki. The oil from the Coratina cultivar also presents higher contents of phenolic compounds (1,725.5 mg kg-1) and tocopherols (437.8 mg kg-1). The major fatty acid in all samples is oleic acid.

title: THE HYLLERAAS METHOD FOR TWO ELECTRONS ATOMS

description: The quantum mechanics of two electrons atoms, as suggested by E. A. Hylleraas in the period between 1928-1930, is discussed in the present work. Hylleraas introduced explicit correlations in the wavefunction by treating the coordinates between the electrons as an independent variable of the problem, an approach that gives very precise energy values. Solution of the problem is given for one, two, three and six basis functions, as in the original work. The solution is also carried out with 140 basis functions, showing that the energy for two electron atoms can be calculated with seven significant figures. Numerical methods presented here are accessible to undergraduated level students.
