title: Electricity cost of rapid filter backwashing in a water treatment plant

description: ABSTRACT This paper aims to determine the cost of electricity for rapid filter backwashing procedures at water treatment plants, whose flow rate is 45 L/s. Flow and electricity consumption were monitored in order to analyze the performance of the pumping systems. Additionally, the effluent water quality of three washes was monitored in filter 4 and a survey of the electricity fare data of the treatment unit was carried out. With the results obtained, it was observed that the effluent turbidity values at the end of the three washes, in this case 31, 30, and 27 NTU, did not reach the minimum values recommended in the technical literature, which is at least 15 NTU. It was also observed the impossibility of prolonging the backwashing time in order to reach the standard of the literature, due to the double function of the elevated washing water reservoir (treated water), whose main purpose is to provide treated water to the water distribution network. Taking into account these limitations and the final quality of the wash effluent, it was observed that the duration of backwashing procedures should be around 380 seconds (6.3 minutes), consuming 23.36 m3/wash. The backwashing procedure cost was estimated at R$ 1.36/m3, which resulted in R$ 31.83/wash. Considering the whole filtration unit, the backwashing procedure cost was R$ 254.64/day, R$ 7,639.20/month, and R$ 91,670.4/year. This value can be classified as too expensive considering the treatment plant studied.

title: The usefulness of high-risk HPV hybrid capture in patients with squamous cell atypia in cervical cytological examination

description: ABSTRACT Introduction: The cervical cytological examination and the investigation of high-risk human papillomavirus (HPV) deoxyribonucleic acid (DNA) are well-known valuable tools for screening of cervical lesions, since they allow the early diagnosis of cancer and its precursor lesions. Objective: This study aimed to evaluate the ability of high-risk HPV DNA detection by hybrid capture to predict intraepithelial lesions and cancer in patients with initial cervical cytological diagnosis of atypical squamous cells (ASC). Method: Retrospective analysis of histological or cervical cytological results after one-year follow-up from hybrid capture for high-risk HPV DNA research in patients with previous ASC diagnosis. Sensitivity, specificity and positive and negative predictive values of hybrid capture were calculated in relation to the identification of squamous intraepithelial lesions. Results: Among the 163 patients previously diagnosed with ASC and absence of high-risk HPV DNA, nine (5.5%) showed low-grade (LSIL) or high-grade squamous intraepithelial lesion (HSIL) during the follow-up. On the other hand, among the 110 patients presenting ASC and high-risk HPV DNA positivity, 43 (39%) showed cervical lesions within one year. Sensitivity and specificity values and positive and negative predictive values applied to hybrid capture for the identification of squamous intraepithelial lesions were 82.3%, 69.3%, 38.1%, and 94.4%, respectively. Conclusion: Our results showed a high negative predictive value of hybrid capture for cervical lesions detection, in patients with previous diagnosis of ASC, when the high-risk HPV DNA research was negative.

title: Quantitative and qualitative evaluation of IgG synthesis in 8,947 cerebrospinal fluid samples

description: ABSTRACT Introduction: Increased intrathecal immunoglobulin class G (IgG) synthesis can be found in several neuroinflammatory diseases. Objective: The aim of this study was to analyze quantitative and qualitative methods of intrathecal immunoproduction evaluation. Methods: We retrospectively assessed data from cerebrospinal fluid (CSF) and serum samples sent to Senne Liquor Diagnóstico from 2001 to 2017. Cytological, biochemical, and immunological data were compared between cases with and without oligoclonal bands (OCBs). Comparisons between samples with OCBs (OCB+) and without them (OCB-) were carried out, and the ability to predict the presence of OCBs was assessed with ROC analysis. Results: We included 8,947 samples (2,599 OCB+ samples and 6,348 OCB- samples). CSF lymphocytes and monocytes were significantly associated with the presence of OCB (p &lt; 0.001). All the inflammatory parameters were significantly associated with OCB, and the methods with the highest predictive ability for OCB were IgG index and Reiber diagram [area under the receiver operating characteristic (AUROC) curve = 0.881 and 0.863, respectively]. A small percentage of cases without OCB had high IgG index (9.56%) or Reiber diagram, showing increased IgG production (4.6%). Conclusion: We showed a strong association between OCB and other CSF inflammatory parameters. The presence of cases with increased quantitative CSF IgG synthesis without OCB suggests that both quantitative and qualitative methods should be performed in the evaluation of neuroinflammatory processes.

title: Benign neural lesions of the oral and maxillofacial complex: a 48-year-retrospective study

description: ABSTRACT Introduction: Peripheral nerve sheath lesions are among the various diseases that can affect the nervous tissue. These neural origin lesions may occur in the maxillofacial region, although they are rare. Objective: The aim of this study was to retrospectively evaluate patient’s profiles presenting benign neural tumors of the oral and maxillofacial complex and carry out comparisons with previous studies. Methods: A descriptive and retrospective study of the clinical records of patients diagnosed with benign oral and maxillofacial neural lesions at the Department of Dentistry of the Universidade Federal do Rio Grande do Norte (UFRN) was carried out, from 1970 to December 2017. Results: From a total of 15,527 histopathological records analyzed over 48 years, 57 (0.37%) corresponded to benign neural lesions, of which 24 (42.11%) were neurofibroma, 15 (26.32%) were traumatic neuroma, nine (15.79%) were neurilemoma, three (5.26%) were granular cell tumor, three (5.26%) were congenital epulis, and three (5.26%) were solitary circumscribed neuroma. Three patients (12.5%) with neurofibroma also presented type I neurofibromatosis. Most patients were female (56.66%), ranging in age from three days to 79 years old. Conclusion: The data obtained confirmed that lesions of neural origin are uncommon in the oral cavity and that neurofibroma is the most frequent, female are the most affected, and the tongue is the most prevalent affected area.

title: Partial tear of the long digital extensor tendon in a dog

description: ABSTRACT: The aim of this paper was to describe the clinical and sonographic findings of partial tear at the musculotendinous junction of the proximal long digital extensor tendon during the acute phase and one year after initial presentation. The dog presented with acute, moderate weight-bearing lameness of the right hind limb. During an orthopedic examination of the stifle, the dog expressed pain on extension and flexion of the right knee. Under general anesthesia, no instability was evident. Radiographic images suggested the presence of joint effusion in the right stifle. Ultrasonography revealed that the long digital extensor tendon was hyperechoic, surrounded by an anechoic effusion, and the muscle fibers were disorganized and interspersed with anechoic fluid. Clinical outcome was considered good after conservative treatment. The dog was re-evaluated approximately one year after treatment and did not present with any clinical signs.

title: Effects of Friction Surfacing on the Characteristics of Consumable Rods of Ti-6Al-4V

description: Friction surfacing (FS) is a coating technique applied mainly in corrosion protection and repair of components. The study addresses the effects of deposition and rotational speeds on the rods characteristics and process efficiency for the deposition of Ti-6Al-4V on self-mating substrates by FS. The consumption rate was 1.8 mm/s, deposition speeds of 8, 16 and 24 mm/s and rotational speeds of 2000, 3000 and 4000 rpm. It was shown that the flash forms primarily at the rod, ascending around the tip and leaving the coating without flash. The higher deposition speeds led to a decrease in rod thickness and diameter. For higher rotational speeds, an increase in diameter and decrease in thickness is observed for the flash on the rod. Experiments have shown that the rotational and deposition speeds have a decisive influence on the flash formation. Its microstructure changes due to the welding process and a change in hardness can be observed.

title: Rubus alutaceus (Rosaceae), a new species for Colombia with agronomic potential

description: Abstract In Gachantivá, Colombia, Rubus alutaceus has been used for commercial purposes for more than one decade but so far with unknown taxonomic identity. For its identification, the anatomical and morphological characteristics of its flowers, fruits, leaves, stems, and seeds, as well as the physicochemical characteristics of its fruits such as color, equatorial and polar diameter, fresh weight, pH and total soluble solids (TSS), were studied. Qualitative and quantitative morphological parameters were evaluated, and longitudinal and transverse cuts were made for histological studies. The plants were found to have trifoliate and pentafoliate leaves; whitish–yellow subglobose polydrupes, fully mature fruits with 8.8°Brix TSS; elliptical, subglobose seeds with ruminated endocarps; anatomical calcium oxalate crystals in the form of druses and raphides in the leaves and branches; and abundant hairs, simple and glandular (colleters) addition to vascular tissue with a more or less continuous appearance. High value in TSS, positively influences fruit agribusiness and the presence of simple hair and colleters can reduce the attack of pests, these variables identify the new species and give it agronomic potential to strengthen its cultivation and marketing.

title: Microclimate and thermal comfort indices in silvopastoral systems under different planting directions and seasons

description: ABSTRACT The orientation of tree-rows in a silvopastoral system associated with different seasons of the year allows more or less sunlight penetration, resulting in deliberate modification of the microclimate composition and thermal conditions provided to animals. In this sense, the aims of this study were to evaluate microclimatic variables and thermal comfort indices for east-west and north-south oriented silvopastoral systems, compared to unshaded systems during summer and winter. The study was conducted at the Modelo II Farm (21° 08’ S 53° 17’ W) at an altitude of 354 m. A randomized block design in scheme of split-split plots with five repetitions was adopted. Two planting directions and a control treatment (unshaded) were evaluated in the plots. Collection times were evaluated in sub-plots, and the distance from eucalyptus trees was evaluated in sub-sub-plots. Changes in the east-west and north-south planting directions did not promote changes in climate variables, nor did they change the thermal comfort indices during summer. There were differences, however, in temperature and relative humidity of the air, black globe temperature, and radiant heat load during winter. Silvopastoral systems provide improvements in the environment and, concomitantly, to the thermal comfort of animals, when compared to unshaded systems. However, thermal stress situations occur despite the presence of trees, depending on the time of the day and the distance from the rows of eucalyptus trees.

title: IS COMMONALITY IN LIQUIDITY A PRICED RISK FACTOR?

description: ABSTRACT Purpose: Analyze if the commonality in liquidity is priced and its relation with the stock return in the Brazilian stock market. Originality/value: Due to the shortage of papers about the effects of commonality in liquidity in the Brazilian financial literature, this paper provides knowledge development about commonality in liquidity effect for the investor, investigating whether an investment strategy in the most sensitive assets to systematic variations of liquidity is attractive for investors, consistent with the risk-return trade off. Design/methodology/approach: In order to identify the effect of commonality to investors, we opted to use portfolios. Using companies listed on B3 as a sample, we estimated regressions developed in the time series from January 2007 to December 2015. Findings: We found that the commonality is a phenomenon present in the Brazilian stock market and their highest values were concentrated in periods of international financial crises. In addition, using portfolios, we observed a premium of 4.165% per month for the commonality in liquidity, although not statistically significant. Finally, we found that the commonality in liquidity is a priced risk factor and when we exposed it to other risk factors we found that the liquidity risk factor was able to partly capture it.

title: Quality of ‘Royal Gala’ cut apple during osmotic dehydration

description: Abstract The present work aimed to evaluate quality parameters of ‘Royal Gala’ apple cubes during osmotic dehydration (OD). We investigated the following OD conditions: osmotic agent, pressure, and temperature. The osmotic agent, being lower after OD with sorbitol than sucrose solutions, mainly influenced the water activity of the product. The color changes increased with increased temperature and were higher in vacuum experiments than at atmospheric pressure. In general, we recommend OD at 25 °C and atmospheric pressure for the preservation of the total phenolic content (TPC) and antioxidant activity (AA) of apple cubes during the process. Peleg’s model was found to provide the best fit of TPC and AA data.
