title: Poultry litter and fresh mulch of Elephant grass improve the organic potato production

description: ABSTRACT The organic production system for potato is usually limited by the occurrence of diseases and nutrient shortage. In these cases, fresh grass mulch and organic fertilization can interact in the foliar late blight infestation and increase the yield and quality of marketable potato tubers, in the organic production system. Aiming to validate this hypothesis, four poultry litter doses (0 Mg ha-1, 10 Mg ha-1, 20 Mg ha-1 and 30 Mg ha-1), which were incorporated into the soil at the pre-planting stage of organic grown potato combined with the presence and absence of fresh mulch (60 Mg ha-1) composed of chopped Elephant grass, were tested. The incorporation of poultry litter into the soil at the pre-planting of potato or the use of fresh grass mulch after the potato hilling inhibits the late blight infestation on leaves, in the organic system. The application of fresh grass mulch after the hilling operation enhances the effect of organic fertilization at the pre-planting of potatoes. The pre-planting application of poultry litter increases the yield and decreases the specific gravities of marketable potato tubers in association with fresh grass mulch. The use of poultry litter at pre-planting and fresh grass mulch improve the sustainable potato cropping in the organic production system.

title: DURATION AND QUALITY OF SLEEP IN SPRINT AND RECOVERY PERFORMANCES AMONG ELITE SWIMMERS

description: ABSTRACT Introduction: Circadian rhythms can impact athletes' sports performance, where the plateau occurs between 15 and 21 hours. Swimming is a peculiar case, as athletes perform training and final sessions in competitions at different times, as in the Rio2016 Olympic Games for example, where the semifinal and final competitions took place from ten o'clock at night. Objectives: (1) to present the protocol of an intervention performed with elite athletes of the Brazilian swimming team during the 2016 Olympic Games in Rio; (2) to find out whether the time at which the competitions were held affected the swimming performances of these athletes during the competition. Materials and Methods: Fourteen athletes of the Brazilian swimming team (males: n= 10; 71% and females: n= 4; 29%) participated in the study. They were followed up during two preparation periods (baseline and intervention) for the 2016 Olympic Games in Rio during June and July 2016. During the competition, we recorded the Reaction Time (RT) and Competition Time (CT) of each athlete in different modalities. The intervention strategies used were light therapy and sleep hygiene. The values of RT at the starting block and CT were registered and conferred with the official results. Results: The athletes showed a decrease in the total time awake (Δ = −13%; Effect size [ES] = 1.0) and sleep latency (Δ = −33%; ES = 0.7), and an increase in total sleep time (Δ = 13%; ES = 1.1; p = 0.04) between the baseline and the period of the intervention, pre-competition. We identified an improvement in the RT (Δ = −2.2% to −1.0%; ES = 0.2 to 0.5) during the competition only for the athletes who participated in the competition finals. Conclusion: We conclude that the intervention carried out was effective in mitigating any negative influence of competition time on the RT and CT of elite athletes of the Brazilian swimming team.

title: Bovine genital campylobacteriosis: main features and perspectives for diagnosis and control

description: ABSTRACT: Bovine genital campylobacteriosis (BGC) is a venereal disease caused by Campylobacter fetus subsp. venerealis. In countries with large cattle herds, such as Brazil, where the use of natural breeding as a reproductive strategy is a common practice, BGC is considered an important cause of reproductive failure and economic losses. In these cases, the bull is the asymptomatic carrier of the bacterium and the infected females can have infertility and even abortions. The techniques for the diagnosis of C. fetus are isolation in culture medium and identification by biochemical tests, immunofluorescence, immunoenzymatic assays and molecular techniques. Disease control is based on vaccination with bacterins. This review described the epidemiology, etiology, pathogenesis, and advances in the diagnosis and control of BGC.

title: Application of queueing models with abandonment for Call Center congestion analysis

description: Abstract This paper studies and applies queueing systems to Call Centers regarding the possibility of customer abandonment from the system before being served due to their impatience in waiting for a service. Call Centers are service organizations that predominantly serve customers via phone calls. One of the main concerns in managing them is to provide quality service at a minimum cost. Noticing the quality of services offered is expressed by customers, for example by abandonment from the queue. This paper shows that the M/M/c+G analytical queueing models with abandonment, with patience time represented by generic distributions (particularly mixed distributions), are more effective than the M/M/c+M analytical queueing models with abandonment, with Exponential patience, commonly used to evaluate congestion problems in Call Centers and support sizing and operational decisions in these systems. We conducted a study using data extracted from a Bank Call Center located in Israel and the parameters and some performance measures are determined based on this data. These sampling measures are compared with the same measures achieved by the M/M/c+M and M/M/c+G analytical queueing models considered in this research, which use parameters obtained empirically and the mixed and non-mixed distributions based on Exponential and Lognormal to represent user patience. An experimental discrete simulation model was also used to explore an alternative scenario, showing the potential of using the approaches based on analytical models with abandonment for Call Center analysis.

title: Adsorption isotherms and isosteric heat in Coffea arabica beans

description: ABSTRACT The knowledge of the adsorption hygroscopic equilibrium in coffee is pertinent for the adequacy of its storage, thus ensuring the quality of the product to the end consumer. The present study aimed to determine the adsorption isotherms of Arabica coffee (Acauã Novo cultivar) beans at the temperatures of 30 ºC, 40 ºC, 50 ºC and 60 ºC, as well as the integral adsorption isosteric heat. The equilibrium moisture contents were obtained by the gravimetric static method, using water activities between 0.10 and 0.83 (decimal). From the obtained data, several mathematical models were fitted to represent the adsorption isotherms. The statistical criteria for selecting the best model were the coefficient of determination, estimated mean standard error, relative mean error and distribution of residues. The Peleg model was the one that best represented the adsorption isotherms of the Arabica coffee beans under the studied conditions. The isotherms showed a sigmoidal type II shape. For a constant water activity, an increase in the temperature promotes a decrease in the equilibrium moisture content of Arabica coffee beans. In a moisture content range between 0.0191 and 0.2534 (dry base), the isosteric heat values ranged from 4,042.19 kJ kg-1 to 2,395.48 kJ kg-1.

title: Phenotype changes of oral epithelial stem cells after in vitro culture

description: Abstract The aim of our study was to isolate populations of keratinocyte stem cells based on the expression of cell surface markers and to investigate whether the culture could affect their phenotype. keratinocytes from human oral mucosa were sorted based on the expression of the epithelial stem cell markers p75NTR and CD71. We also examined the co-expression of other epithelial stem markers such as integrins β1 and α6 and their stem cell-like proprieties in in vitro assays. Three passages after being sorted by MACS, more than 93% of the p75NTR+ve cells lost the expression of p75NTR, while 5.46% of the p75NTR-ve gained it. Within the small population of the p75NTR+ve cells, 88% co-expressed other epithelial stem cell markers such as integrins β1 and α6, while only 28% of p75NTR-ve cells co-expressed these markers. These results were confirmed by sorting cells by FACS. Additionally, when double staining was used for sorting cells, 99% of the p75NTR+veCD71-ve and 33% of the p75NTR-veCD71+ve cells expressed both integrins, but just one week after culture, only 1.74% of the p75NTR+veCD71-ve cells still expressed p75NTR and only 0.32% still expressed CD71. Similar results were obtained when co-culturing p75NTR+ve and p75NTR-ve populations before analysis. Our results suggest that phenotype changes may be part of an intrinsic cellular mechanism to conserve levels of protein expression as they may found in the human body. In addition, in vitro culture may not offer ideal conditions for epithelial stem cell maintenance due to phenotype changes under standard culture conditions.

title: Tomato production as a function of aeration levels after subsurface drip irrigation

description: ABSTRACT After rain or irrigation, the soil pores may present a low oxygen content (hypoxia). Soil aeration after irrigation has been used to overcome hypoxia-based problems. This study aimed to investigate the effect of four aeration levels (0, 0.5, 1.0 and 1.5 times the standard volume) applied after irrigation, using a subsurface drip system, at two soil depths (0.15 m and 0.30 m). A randomized block design was used, in a 4 x 2 factorial scheme, with six replications. The yield characteristics assessed were: total fruit mass per plant, average fruit mass and number of fruits per plant. The growth characteristics were root and stem dry mass. The water-use efficiency was also calculated. The results indicated that the highest aeration level, at a depth of 0.30 m, increased the yield by 41.2 %, when compared with plants that received only irrigation, at the same depth. The water-use efficiency was influenced by the soil aeration after irrigation only at the depth of 0.30 m.

title: Advanced carcinoma of the oropharynx: survival analysis comparing two treatment modalities

description: Abstract About 92,000 new cases of oropharynx carcinoma are expected to occur annually worldwide. There is no consensus about the best therapy for these advanced tumors. The objective of the present study was to evaluate overall and disease-free survival rates of patients with advanced oropharynx squamous cell carcinoma, comparing surgery + radiotherapy with chemotherapy + radiotherapy. Medical records of patients were reviewed. Previously treated tumors were excluded. Clinical, demographic and microscopic information was collected, and p16 staining was performed. Kaplan-Meier survival curves were plotted. Forty-seven cases were included, 41 men and 6 women, having a mean age of 56.3 years. Most patients were smokers (85.1%) and consumed alcohol (74.5%). Patients were stage III (21.3%) or IV (78.7%). Most lesions affected the base of the tongue (36.2%). Of the 23 cases available for p16 testing, 3 were positive (13.0%). There was no difference between the overall and the disease-free survival rates for the two treatment modalities (p&gt;0.05), even when only resectable tumors were compared. Seventeen cases experienced recurrence (36.2%); 16 (34.0%) patients remained alive without disease; 15 (31.9%) died due to disease; 9 (19.2%) were recurrent at the last follow-up. The two treatment protocols were equally efficient in treating advanced oropharynx squamous cell carcinoma, since both promoted similar overall and disease-free survival rates. The results and interpretations related herein mostly regard “conventional” oropharyngeal squamous cell carcinomas, as opposed to HPV-associated tumors.

title: Use of agro-industry residues as substrate for the production of Euterpe precatoria seedlings

description: ABSTRACT The availability of single assai palm (Euterpe precatoria) seedlings with good quality is a fundamental requirement to expand the cultivation of the species. This study aimed to assess the use of fruit agro-industry residues as substrate for producing single assai seedlings. The experiment was carried out under nursery conditions, in a completely randomized design, with four replications and eight plants per plot. Fifteen treatments were evaluated: a commercial substrate, four dry and crushed agro-industrial residues (Brazil nut shell, acerola pit, assai pit and cupuassu peel) and ten combinations of these materials in the proportion of 1:1. The following variables were also measured: shoot height; stem diameter; number of leaves; shoot, root and total dry mass; and Dickson Quality Index score. The substrate formulated with Brazil nut shell + acerola pit stood out for promoting a higher growth and dry biomass, resulting in seedlings with a better quality. The pure assai pit residue was not efficient for producing seedlings, but it showed a good potential when mixed in equal proportion with other materials (e.g. Brazil nut shell and cupuassu peel).

title: Soil water availability for drip-irrigated common bean crop

description: ABSTRACT Minimum limits of soil water storage should be established for the irrigation management of crops, in order to satisfactorily provide water to plants. This study aimed to define the soil water availability factor (f factor) that provides the maximum agronomic yield and maximum water-use efficiency for drip-irrigated common bean cultivars. The experiment was carried out in a randomized block design, with four replications. The treatments were arranged in split plots, with the plots consisting of f factors (0.20, 0.35, 0.50, 0.65 and 0.80) and subplots consisting of common bean cultivars (BRS Pérola and BRS Estilo). The use of f factors between 0.30 and 0.35 is recommended for common bean crops to obtain the maximum agronomic yield and maximum water-use efficiency. The BRS Estilo cultivar presents a water-use efficiency 16 % higher than the BRS Pérola.
