title: Abiotic factors and photosynthetically active photon density affect the physiological mechanisms of jaboticaba

description: ABSTRACT In fruit species, the amount of solar energy absorbed can influence fruit quality; hence, ensuring optimal light distribution management in the canopy of plants is essential. Therefore, the objectives of this study were (i) to analyze the variations in gas exchange through the day and (ii) identify the photosynthetically active photon flux density (PPFD) that promotes higher chlorophyll fluorescence and electron transport rate in jaboticaba seedlings. The experimental design was completely randomized, with treatments consisting of 18 photosynthetic photon flux densities and three evaluations throughout the day. Six replicates were used, with two plants per plot. Gas exchange and chlorophyll a fluorescence in P. peruviana were altered due to fluctuating photosynthetic photon flux density (0; 25; 50; 75; 100; 125; 150; 175; 200; 400; 600; 800; 1,000; 1,200; 1,400; 1,600; 1,800; and 2,000 μmol m-2 s-1) and environmental conditions throughout the day (8:00 a.m., 12:00 and 4:00 p.m.). The higher PPFD (1,384.6 μmol m-2 s-1) and air temperature (39.74 °C) at noon (12:00 p.m.) favored gas exchange in this species. An increase in PPFD of up to 1,000 μmol m-2 s-1 positively influenced the gas exchange and chlorophyll a fluorescence of P. peruviana.

title: EVALUATION OF AROMATIC VOLATILE ORGANIC COMPOUNDS IN THE ATMOSPHERE IN CAMPOS DOS GOYTACAZES AND ITAPERUNA APPLYING MULTIVARIATE DATA ANALYSIS

description: Volatile Organic Compounds (VOCs) are air pollutants emitted from different sources, mainly by industries and motor vehicles. The evaluation of the emission of these compounds into the atmosphere should be done systematically and with a varied class of compounds. The large number of data generated during the monitoring of these VOCs requires the use of multivariate data tools to interpret the results. In this sense, this work aimed to monitor 10 aromatic VOCs present in the atmosphere of the largest cities in the Norte Fluminense (Campos dos Goytacazes) and Noroeste Fluminense (Itaperuna) regions. The VOCs were actively sampled and analyzed by gas chromatography with mass spectrometry detection after thermal desorption. After treatment of analytical results, it was observed that in both cities there is influence of vehicular emissions. In the city of Itaperuna, due to the relief and lower dispersion of contaminants, there is a higher occurrence of photochemical reactions. The exploratory analysis of the data allowed identifying the variables that were more significant and correlating these variables with the main sources of emission of the compounds. This is the first study of VOCs evaluation in Campos dos Goytacazes and Itaperuna, demonstrating the relevance of this research for understanding the behavior of VOCs in these cities, which have different reliefs and high traffic of cars and trucks in the studied sites.

title: AN ACCESSIBLE GLOVE BOX PROJECT FOR PROCEDURES THAT REQUIRE INERT CONDITIONS

description: An inert atmosphere is, in some cases, important for the performing of experiments where substances are toxic and/or sensitive to oxygen. However, the high cost and accessibility of an equipment to work under these conditions, results in the fact that most laboratories do not have this kind of equipment. In this paper, we present a simple and efficient project to build a cheap glove box for processes that require an inert atmosphere. The proposed glove box is made using medium density fiberboard (MDF), an acrylic lid, hinges, air valves, PVC gloves and other materials that can be found easily in local stores or on the internet. Tests to verify the quality of the nitrogen atmosphere were performed using the lighter test and niobium pentachloride (NbCl5), which is a moisture/ oxygen sensitive material. The results demonstrated that the equipment is able to maintain an inert atmosphere for several hours, does not permit lighter to function and maintains the NbCl5 stable.

title: Graphite action on the longitudinal distribution of soybean seeds in mechanical and pneumatic feeders

description: ABSTRACT. The use of powdered graphite as a solid lubricant to reduce friction among soybean seeds during mechanical sowing aims to facilitate the seed flow into the seed reservoir, while reducing mechanical damage to the seed. The objective of this study was to evaluate the influence of graphite on the longitudinal deposition of soybean seeds using mechanical and pneumatic feeders at different distribution velocities. The experiment was performed on a static simulation-test bench, with a completely randomized design with two varying factors: graphite dose (0, 1, 2, 4, and 8 g kg-1 seed) and distribution velocity (5, 7, 9, and 11 km h-1 for the pneumatic feeder; and 3, 5, 7, and 9 km h-1 for the mechanical feeder). To assess the homogeneity of seed distribution, the frequency of parameters such as double, flawed, and acceptable spacings, coefficient of variation, and precision index were evaluated from five repetitions of 250 spacing each. For the pneumatic feeder, the optimal values to maximize precision of seed deposition were 4.6 g kg-1 and 6.7 km h-1 of graphite dose and distribution velocity, respectively. In turn, the optimal values to minimize undesirable spacing while maximizing accuracy with the mechanical feeder were 4.9±0.6 g kg-1 and 4.9±0.3 km h-1. Overall, regardless of feeding mechanism, the use of graphite promoted greater efficiency in the distribution of seeds owing to the higher level of fluidity inside the reservoir; however, high doses can cause the opposite effect. In addition, an excessive increase in speed influenced seed distribution negatively.

title: Comparison between speedy and content-balanced versions of the Pediatric Evaluation of Disability Inventory - Computer Adaptive Test (PEDI-CAT) in children with cerebral palsy

description: ABSTRACT This study aimed to compare the speedy and content-balanced versions of the Pediatric Evaluation of Disability Inventory - Computer Adaptive Test (PEDI-CAT) in its four domains. A cross-sectional observational study was conducted with children with cerebral palsy (CP). The two versions of PEDI-CAT were administered to each child with a 7-days interval, remotely, in interview format with caregivers. Pearson’s correlation was used to evaluate the association among scaled scores in the two versions of PEDI-CAT. In total, 11 children with CP, aged 2 to 12 years, participated in the study. A strong significant association between mean values of the scaled score of the speedy and content-balanced versions in all domains (p&lt;0.0001) was observed. Two children (18.2%) were classified differently regarding normative standard score in the Social/Cognitive domain. Both versions of PEDI-CAT showed concordant results in relation to the scaled score when applied to children with CP. However, one must cautiously interpret the normative standard score depending on the version used in the Social/Cognitive domain.

title: Energy Quality of Wood and Charcoal from the Stem and Root of Eucalyptus spp.

description: Abstract This work aimed to evaluate the energy quality of wood and charcoal obtained from the stem and root of the genus Eucalyptus spp. From the wood, the physical, chemical and energetic properties were evaluated. For the charcoal produced in ovens of the carbonization furnaces model in the industry and produced in a muffle furnace, the physical, chemical and energetic properties were evaluated. Based on the analysis of technological properties, wood from the root has higher basic density (731.45 kg m-3) and lignin content (26.44%), however, the fixed carbon content and higher calorific value of the root (17.54% and 4547.75 kcal kg-1) were lower than for the stem wood (21.36% and 4730.82 kcal kg-1). It is recommended to use the wood from the root, both for direct burning and for the production of charcoal. The charcoal obtained in the industry, compared to that produced in muffle, presented higher energy quality.

title: Influence of Rhythmic Auditory Stimulation using music associated with physical therapy on depressive symptoms in Parkinson’s

description: ABSTRACT Depressive symptoms are commonly found in Parkinson’s disease and are considered an important factor for an individual’s poor quality of life and disability. Therapeutic interventions based on rhythm and music, such as rhythmic auditory stimulation, have been used to treat the mobility and seem to positively influence on mood. This study aims to evaluate the effect of rhythmic auditory stimulation using music associated with physical therapy on mood in individuals with Parkinson’s, with an emphasis on depressive symptoms. This is a quasi-experimental study with a final sample of 18 patients aged 40-80 years, with a clinical diagnosis of idiopathic Parkinson’s disease, in the mild to moderate stages of the disease. Patients were randomized into two groups: Rhythmic Auditory Stimulation and Control Groups. Depressive symptoms were assessed using the Portuguese version of the Beck Depression Inventory. Both groups reduced their The Beck Depression Inventory scores. However, only in the Rhythmic Auditory Stimulation Group the reduction was significant, with a mean difference in the inventory score three times greater than the Control Group.

title: Dividend-yield variation as an asset selection criterion in momentum strategies of Brazilian real estate investment trusts

description: ABSTRACT We aimed at showing the usage of the dividend-yield (DY) variation as a criterion for selecting Brazilian real estate investment trusts (BR-REITs) in momentum strategies. The identification of momentum in BR-REITs with this selection criterion is, to the best of our knowledge, new and gives rise to different strategies that seize abnormal returns. This study allows a new understanding of the dynamics between prices and dividend payments, which compose BR-REITs returns. It is of major importance, considering the relevance of the DY ratio for the asset class. The studied strategies delivered results above the industry’s index with expressive magnitude, are of simple elaboration, and can be applied by any individual or institutional investor. Portfolios’ performances were measured by Sharpe ratio (SR), alpha of the Fama and French three-factor model, and excess returns obtained in relation to the BR-REITs’ index. Statistical tests were applied to verify the significance of the results. This study showed that strategies around the momentum effect that buy (sell) BR-REITs with greater (smaller) DY variations in previous months tended to have superior performance to the industry’s index.

title: Profile of physical therapy in the rehabilitation of individuals with Alzheimer’s disease: a cross-sectional study

description: ABSTRACT This study analyzes the working profile of physical therapists from the states of Rio de Janeiro (RJ) and Rio Grande do Sul (RS) in the management of people with Alzheimer’s disease (AD). A total of 256 responses were obtained to a questionnaire sent via the electronic address of the Regional Councils of Physical Therapy and Occupational Therapy (CREFITOS) 2 (RJ) and 5 (RS), from March to December 2020. The questionnaire comprises 36 closed questions, the variables of which were grouped into: (1) sample characterization; (2) specific data on the profession of physical therapist; and (3) issues related to AD. In this article, only issues related to AD will be analyzed. All questions were multiple choice with 2 to 15 options of answer. Most respondents (88.3%) had already treated patients with AD, but 50.8% needed to review the literature to assist these patients. The main objective reported in the management of the individual with AD was to “delay the progression of motor losses.” The practices were significantly different according to the stage of the disease (p&lt;0.001). More than 85% of the participants cited as a benefit that physical therapy “delays physical dependence.” This study shows the need for further studies that specifically address the intermediate and advanced stages of AD since the current literature is inconclusive and with little evidence regarding physical therapy in the management of this population, making it impossible to create manuals and /or standardization of specific practices for each stage.
