title: Effect of protein supplementation on yield and milk composition of F1 Holstein x Zebu cows kept in deferred pasture of brachiaria grass

description: ABSTRACT The objective of this study was to evaluate different supplementation strategies concentrated to F1 Holstein x Zebu lactating cows managed in deferred signal grass pasture on the yield and composition of milk and body weight gain. Thirty six F1 Holstein x Zebu cows with an average lactation period of 267 ± 10 days, mean body weight of 548 ± 19kg were used following a completely randomized design in a 4 x 5 factorial scheme, being four feeding strategies and five days under evaluation. The treatments consisted of four nutritional strategies: deferred pasture as a source of roughage without supplementation (PDSS); deferred pasture as a source of roughage with protein supplement offer (PDCS); deferred pasture supplemented with 15 kilos of corn silage (natural base) + 1,200 grams of protein supplement (PDSP) and corn silage (ad libitum) + 700 grams of protein supplement (SMP). There was no interaction (P&gt; 0.05) between the nutritional plans and days under evaluation for any of the variables. It was found that cows fed SMP showed milk production 26.06% higher than the other nutritional plans (mean of 11.46kg/day). F1 Holstein/Zebu cows handled in deferred pasture in a traditional way supplemented with protein maintains milk yield.

title: Water quality of the Paraná river in a bathing resort region: a discussion on the potential impacts of secondary treated wastewater discharge

description: ABSTRACT The headwater of the Paraná River became the recipient water body for the Aparecida do Taboado’s Wastewater Treatment Plant effluents - Mato Grosso do Sul - in a project started in 2013 and completed in 2020. The emissary is located upstream of a bathing resort. This study aimed to monitor the river water quality before discharge starts, from August 2019 to February 2020. The CETESB Water Quality Index and its calculation parameters were used. The Paraná River presented good water quality (Water Quality Index CETESB ≥72) and the absence of Escherichia coli. Nevertheless, 57 and 61% of the samples did not meet CONAMA Resolution No. 357/05 for biochemical oxygen demand and total phosphorus, respectively. Potential negative impacts on the water quality are related to the parameters of biochemical oxygen demand, total phosphorus and Escherichia coli and the secondary treated wastewater discharge into Paraná River may result in the water quality deterioration, compromising its multiple uses.

title: Building maintenance with emphasis in plumbing systems: a systematic review of the literature

description: ABSTRACT With the increasing demand for buildings, it is necessary that conservation and maintenance practices of building systems be properly specified and fulfilled. This research is a systematic review of the literature about the importance, consequences, and performance of plumbing systems. The search for articles was carried out on the Portal de Periódicos Capes covering the period from 2007 to 2017. 252 articles were found, but, based on the topic, just 26 were selected. The content of the articles was discussed in five research questions, including failures in plumbing systems, building maintenance, and assessment tools for plumbing performance and susceptibility to risks. It was observed that the failures in plumbing systems are common, mainly problems with leaks, which result in financial, time, and emotional costs for users. In addition, many of these pathological manifestations are related to the absence or failure of maintenance. However, maintenance is greatly influenced by factors such as material type, costs, and user expectations, requiring efficient maintenance programs and qualified teams to ensure the performance of the building and its systems. In addition, some tools have been developed in order to assess the building systems performance and susceptibility to risks, helping in the decision-making of maintenance and design phase.

title: Global endothelial function assessment using pulse wave analysis in hypercholesterolemia

description: Abstract To compare global endothelial function assessed by pulse wave analysis (PWA) using the ratio of endothelium dependent vasodilatation (EDV) to endothelium independent vasodilatation (EIV) in patients with hypercholesterolemia and controls. 92 subjects [46 hypercholesterolemics, 46 controls] were studied at standardized conditions. Baseline augmentation index (AIx) was assessed followed by the administration of 0.5 mg sublingual nitroglycerine, an endothelium independent vasodilator. AIx was assessed and the maximum change in AIx after nitroglycerine was recorded as EIV. After a washout period of 30 minutes, 400 µg of inhaled salbutamol, an endothelium dependent vasodilator was administered. AIx was assessed again and the maximum change in AIx after salbutamol was recorded as EDV. Global endothelial function was calculated as EDV:EIV ratio. EDV and EIV in patients with hypercholesterolemia compared to controls were 2.97 ± 3.95 and 6.65 ± 3.80 (p&lt;0.001); and 13.41 ± 4.57 and 15.88 ± 4.78 (p=0.01) respectively. EDV:EIV ratio was significantly reduced in patients with hypercholesterolemia compared to controls; 0.21 ± 0.38 and 0.44 ± 0.24 (p&lt;0.001) respectively. EDV:EIV ratio was significantly reduced in patients with hypercholesterolemia compared to controls. PWA is a potential clinical tool to assess global endothelial function in patients with hypercholesterolemia.

title: Diagnosing sub-acute rumen acidosis in cows in the post-calving period with digital technologies

description: ABSTRACT This study aims to determine the relationship between indicators of the motor activity, pH factor, rumen and rectal temperature within 10 days after calving and to analyze the possibility of using the studied parameters as prognostic signs for diagnosing sub-acute rumen acidosis (SARA). The measurements were taken using bolus with sensors designed to monitor cow health. The motor activity, pH factor and ruminal temperature of 10 cows were measured during 10 days at a measurement interval of every 60 seconds. Next, the researchers calculated the average values of the obtained readings, which were divided into 2 groups according to a measurement interval of every 12 hours. Rectal temperature was measured using a veterinary thermometer every 12 hours (at 8 a.m. and at 8 p.m.). As a result, 200 measurements were obtained. Descriptive sampling statistics were calculated using the SPSS Statistics program. An increase in motor activity reduces the pH level of the rumen environment. Lowering the pH factor of the rumen environment leads to an increase in ruminal temperature. There is a positive statistically significant correlation between ruminal and rectal temperature. The nosology of SARA can be predicted by measuring the motor activity and rectal temperature of dairy cows.

title: Briquettes production from green coconut shells: technical, financial, and environmental aspects

description: ABSTRACT The United Nations Sustainable Development Goals emphasize the need to better understand and propose solutions for the growing demand for resources and the generation of waste by anthropic systems at any scale and intensity. Although it can be considered as secondary importance problem, hundreds of tons of green coconut shell residues annually generated in the Brazilian coastal cities are transported and dumped in landfills, wasting their energy potential and resulting in economic and environmental problems – this approach is known as take, make, disposal, or “linear” production model. This work proposes a “circular” model by using the biomass from green coconut shells generated by the cities of Baixada Santista region as a raw material for briquettes production. Technical-operational, environmental, and financial aspects are considered to assess the proposed “circular” model in comparison with the existing “linear” model. Results show that technical-operational aspects of the “circular” model are viable due to already existing technologies in the market that can be easily adapted for the purposes in converting green coconut shells into briquettes. The “circular” model proposed allows a reduction in greenhouse gases emission by ∼40 thousand tons year−1 when compared to the “linear” model, besides avoiding leachate generation. Furthermore, the 66% profitability, 195% rentability, and 6 months of investment payback suggest the financial viability of briquettes production. Together, all these indicators claim for public policies incentives and private investments to make the proposed “circular” model a reality, which is aligned with the objectives of 2030 agenda.

title: Limonium brasiliense (Boiss.) Kuntze Seeds: Disinfestation and Conservation of Viability Under Storage

description: Abstract This study evaluated the effect of disinfestation methods and different storage environments on the germination of seeds of Limonium brasiliense (Boiss.) Kuntze. Seeds were disinfested using ethanol followed by sodium hypochlorite; water under agitation; and no disinfestation from two origins. Longevity was tested by storing the seeds in a cold chamber, dry chamber, and at ambient laboratory temperature. Beginning of germination (BG), percentage (%G), and mean germination time (MGT) and mean germination speed index (MGSI) were evaluated. Data were submitted to an analysis of variance, comparison of mean values and a polynomial regression analysis (p&lt;0.05). In the disinfestation, there was significant difference in %G and MGT only between origins. For longevity, IG and MGSI had a positive and negative linear behavior, respectively, while %G had a quadratic behavior. L. brasiliense seeds disinfestation does not affect germination. Dry chamber was the most suitable storage environment.

title: Diversity and Composition of a Seed Bank in the Subtropical Atlantic Forest, Southern Brazil

description: Abstract The current study aimed to evaluate the seed bank diversity and composition found in the Municipal Natural Park São Francisco de Assis (PSFA), Santa Catarina, Brazil, located within the subtropical Atlantic Forest. Samplings were carried out within four different locations (n = 20 sample plots per location). All samples were kept in suspended beds for germination, growth, and subsequent species identification. We were able to identify 85 morphospecies (1,016 individuals). Most of them were categorized as pioneers. Pioneers were also the ecological category that had more individuals (73.12%). The predominant dispersion syndrome was zoochoric, with 58 taxa included. Our results indicate that the seeds are being provided by species that occur around the park, in some cases favored by recent landslides in the area.

title: Strategic ventilation reduces non-ventilated contralateral lung injury induced by one-lung ventilation in rabbits

description: ABSTRACT One lung ventilation (OLV) often results in trauma to the unventilated contralateral lung. This study aims to evaluate the effects of different OLV regimens on the injury of the unventilated contralateral lung to identify the best conditions for OLV. Forty rabbits were divided into five groups: a sham group, OLV group I (fraction of inspired oxygen (FIO2) 1.0, tidal volume (VT) 8mL/kg, respiratory rate (R) 40 breaths/min and inspiratory/expiratory ratio (I:E) 1:2), OLV group II (FIO2=1.0, VT 8mL/kg, R 40 breaths/min, I:E 1:2, and positive end-expiratory pressure (PEEP) 5 cm H2O), OLV group III (FIO2 1.0, VT 6mL/kg, R 40 breaths/min, I:E 1:2 and PEEP 5 cm H2O) and OLV group IV (FIO2 0.8, VT 6mL/kg, R 40 breaths/min, I:E 1:2 and PEEP 5 cm H2O). Animals from all OLV groups received two-lung ventilation (TLV) to establish a baseline, followed by one of the indicated OLV regimens. The rabbits in the sham group were intubated through trachea and ventilated with fresh air. Arterial blood gas samples were collected, lung injury parameters were evaluated, and the concentrations of TNF-α and IL-8 in bronchoalveolar lavage fluid (BALF) and pulmonary surfactant protein A (SPA) in the unventilated lung were also measured. In OLV group I, the unventilated left lung had higher TNF-α, IL-8 and lung injury score but lower SPA than the ventilated right lung. In OLV groups I to III, the concentrations of TNF-α, IL-8 and lung injury score in the left lung decreased but SPA increased. No differences in these parameters between OLV groups III and IV were observed. Strategic ventilation designed for OLV groups III and IV reduced OLV-induced injury of the non-ventilated contralateral lung in rabbits.
