title: Development of eco-efficiency comparison index through eco-indicators for industrial applications

description: Abstract In the last decades companies aligned with the concepts and principles of sustainable development have been seeking to minimize the environmental and social impacts caused by their operations. Typically, the primary environmental concerns in the industry were related to water consumption, wastewater production, waste generation, energy consumption and mainly CO2 emission - which is one of the causes of the greenhouse effect. However, the environmental eco-efficiency is not clearly seen when the evaluations of these eco-indicators are individually used and, therefore, it becomes necessary to implement a methodology that enables a joint assessment involving various aspects. In this paper we have developed an environmental index, called Eco-efficiency Comparison Index (ECI), applied to evaluate in real time a petrochemical facility. Throughout a study-case based on experimental data, the results have evidenced that the ECI is a useful tool for eco-efficiency analysis for process monitoring.

title: Risk factors and infection due to Cryptosporidium spp. in dogs and cats in southern Rio Grande do Sul

description: Abstract This study investigated the frequency of oocysts of Cryptosporidium spp. in feces from dogs and cats in five municipalities in the southern region of the state of Rio Grande do Sul. The risk factors associated with infection were also investigated. Feces samples from 110 dogs and 18 cats were stained using the auramine method. At the time of feces sampling, a questionnaire with semi-open-ended questions was applied to the animal guardians and all data obtained underwent statistical analysis. The real frequency of oocysts of Cryptosporidium spp. was 24.63% (27 dogs and two cats). Only four samples of dog feces were diarrheic and no presence of oocysts was observed in any of them. Variables that represented risk factors for infection were: homemade food, untreated water, circulation of animals on grassy terrain and living in the same environment as other animals (cattle). The results made it possible to inferring that within the population studied, the frequency of parasitism due to Cryptosporidium spp. in dogs was relevant and emphasize the asymptomatic nature of this infection. The adopting control measures are highlighted, particularly in relation to variables that represent risk factors for this infection.

title: Experimental study of the diffusion-controlled corrosion of copper in the bottom of a jet stirred reactor

description: Abstract Jet stirred tank reactors are usually preferred to mechanically stirred tank reactors in the case of high pressure stirred tank reactors in order to avoid the mechanical problems inherent with mechanically agitated reactors. Owing to the impact force exercised by the fluid jet on the tank bottom, the tank bottom is subjected to severe corrosion. The aim of the present work is to address this problem using an accelerated system which simulates natural diffusion-controlled corrosion of metals. Diffusion-controlled corrosion of a fixed copper disc, at the bottom of a cylindrical tank, under a single phase forced jet flow of acidified dichromate solution was investigated. Variables studied were: physical properties of the solution, solution velocity through different diameters of jet nozzle, distance between the jet outlet nozzle and the copper disc surface; and the effect of using a drag reducing polymer. An overall correlation was obtained: Sh = 0.579 Sc 0.33 Re 0.975 (h/d) 0.049 valid for 850 &lt; Sc &lt; 1322, 1852 &lt; Re &lt; 5000 and 0.3 &lt; h/d &lt; 1.2. Addition of polyethylene oxide as a drag reducing polymer was found to diminish the rate of corrosion under single phase forced jet flow by an amount depending on the operation conditions.

title: Sonographic patterns of Peyronie's disease in patients with absence of palpable plaques

description: ABSTRACT Purpose Non-palpable isolated septal plaques of the penis are likely present in a significant number of patients affected by erectile dysfunction (ED) and penile pain without deformity or curvature. The aim of this study was to evaluate the ultrasound (US) patterns observed in patients investigated for ED or penile pain without curvature. Materials and Methods We reviewed the medical records of 386 patients who underwent an initial colour-Doppler ultrasonography (CDU) of the penis for DE and/or penile pain without curvature. After satisfying inclusion criteria, 41 patients were individualized. All patients had a non-palpable plaque with involvement of the penile septum. Three US patterns were identified: focal hyperecoic thickening of the intercavernosum septum (IS) with acoustic shadow (pattern 1), non-calcified thickening (isoechoic or slightly hyperechoic (pattern 2), and microcalcifications in the IS without associated acoustic shadow (pattern 3). Results Patients’ mean age was 51.3±16.7. ED was the predominant disorder in 73.2% of patients, followed by penile pain and length loss in 19.5% and 7.3% of patients, respectively. 32(78.1%) patients showed the pattern 1, 6 (14.6%) pattern 2, and 3 (7.3%) pattern 3. Plaques size varied from 3 to 13 mm. The penile hemodynamic response to CDU reported abnormal findings distally to the septal plaques in 20 patients (&lt;25cm/sec). Median left and right cavernosum artery flows measured a peak systolic velocity of 31cm/sec and 33 cm/sec, respectively. Conclusions We believe that an US study with CDU provides a way to characterize, localize, and deliver treatment choice in patients with Peyronie's Disease.

title: School Trajectory of Students with Disabilities in the Youth and Adult Education, High School Level

description: ABSTRACT: This study aimed to identify the school trajectory of students with disabilities enrolled in Youth and Adult Education (called EJA) at High School level. It is a descriptive research with a qualitative approach, which counted on the participation of 10 students from different schools, from the state network in the hinterland of the state of São Paulo, Brazil. Among the results, we can observe the moving from one school to another throughout the schooling process, difficulties reported during the course of the inclusive process, desire to continue with the studies. The school is also seen as a possibility of development for the labor market. We concluded, when analyzing the school trajectories, that EJA is seen as an opportunity for social insertion, either through future professional education or entry into the labor market. However, present challenges were observed for the effectiveness of inclusion in the context of EJA, mainly related to physical and curricular accessibility.

title: Transperitoneal vs. extraperitoneal radical cystectomy for bladder cancer: A retrospective study

description: ABSTRACT Purpose Conventional transperitoneal radical cystectomy (TPRC) is the standard approach for muscle invasive bladder cancer. But, the procedure is associated with significant morbidities like urinary leak, ileus, and infection. To reduce these morbidities, the technique of extraperitoneal radical cystectomy (EPRC) was described by us in 1999. We compared these two approaches and the data accrued forms the basis of this report. Materials and Methods All patients who underwent radical cystectomy for bladder cancer by the author (JNK) with follow-up for at least 5 years were included. A total of 338 patients were studied, with 180 patients in EPRC group and 158 in TPRC group. Results There were 3 mortalities within 30 days in TPRC group and one in EPRC group. Early complication rate was 52% and 58% in EPRC and TPRC groups. Urinary leak occurred in 31 (9.2%) patients (13 in EPRC, 18 in TPRC, p=0.19). Gastrointestinal complications like ileus occurred in 9 (5%) patients in EPRC group and in 25 (15.8%) patients in TPRC group, (p&lt;0.001). Wound dehiscence occurred in 29, and 36 patients in EPRC and TPRC groups respectively. The reoperation rate was 6.1% and 12% in EPRC and TPRC groups, (p=0.08). Intestinal obstruction were significantly less in EPRC group (1.7% vs. 7.8% in TPRC group, p=0.002). Uretero-enteric anastomosis stricture was seen in 10 patients (4 in EPRC, 6 in TPRC, p=0.39). Conclusions The EPRC is associated with decrease gastrointestinal complications, ease of management of urinary leaks, and low reoperation rates. Thus EPRC appears safe functionally and oncologically.

title: Abundance and population structure of Plesionika narval (Fabricius, 1787) in the Northeastern Atlantic

description: Abstract Analysis of abundance and population structure of Plesionika narval was performed on data concerning 5,255 specimens obtained from 62 fishing sets carried out off the Madeira archipelago (Northeastern Atlantic) between 2004 and 2008 in a depth range from 101 to 350 m. Abundance ranged from 0.01 to 19.74 specimens-per-trap and significant differences were found between seasons, probably as a result of an increment of population in the spring during the recruitment season. The analysis of size distribution revealed that the carapace length (CL) ranged from 2.45 to 28.61 mm and that mean female size consistently exceeded that of males. Differences in mean CL were statistically significant between depth strata and seasons. Of the specimens sampled, 57.00% were males, 41.88% females and 1.42% undetermined. Sex ratio also differed significantly between seasons according to depth strata, consolidating the hypothesis of the existence of seasonal migrations related with the reproductive cycle of this species. Ovigerous females showed larger sizes and occurred all year around and remain in shallow waters in winter, summer and autumn and move to deeper waters in spring. The highest frequency of ovigerous females was recorded in summer, between 151 and 200 m deep supporting the hypothesis that spawning of this species occurs in shallow waters, especially in late summer.

title: Detection and molecular characterization of Cryptosporidium spp. in captive canaries (Serinus canaria) using different diagnostic methods

description: Abstract This study used several diagnostic methods to examine the occurrence of and molecularly characterize Cryptosporidium spp. in captive canaries (Serinus canaria) in southern and southeastern Brazil. A total of 498 fecal samples were purified by centrifugal-flotation using Sheather's solution. Cryptosporidium spp. diagnosis was performed using three diagnostic methods: malachite green negative staining, nested PCR targeting the 18S rRNA gene, followed by sequencing the amplified fragments, and duplex real-time PCR targeting the 18S rRNA specific to detect Cryptosporidium galli and Cryptosporidium avian genotype III. The overall positivity for Cryptosporidium spp. (total samples positive in at least one protocol) from the microscopic analysis, nested PCR and duplex real-time PCR protocol results was 13.3% (66/498). The positivity rates were 2.0% (10/498) and 4.6% (23/498) for Cryptosporidium spp. by microscopy and nested PCR, respectively. Sequencing of 20 samples amplified by nested PCR identified C. galli (3.0%; 15/498), Cryptosporidium avian genotype I (0.8%; 4/498) and Cryptosporidium avium (0.2%; 1/498). Duplex real-time PCR revealed a positivity of 7.8% (39/498) for C. galli and 2.4% (12/498) for avian genotype III. Malachite green negative staining differed significantly from nested PCR in detecting Cryptosporidium spp. Duplex real-time PCR was more sensitive than nested PCR/sequencing for detecting gastric Cryptosporidium in canaries.

title: Comparative study of three xenic media culture for cultivation of Balantidium coli strains

description: Abstract The aim of the present study was to evaluate the growth rate of Balantidium coli in three xenic media cultures. Between 2013 and 2015, 10 B. coli isolates obtained from feces of Cynomolgus macaques, and 30 isolates from feces of pigs were studied. An inoculum of 500 trophozoites was transferred to tubes containing LES, TYSGM-9 and Pavlova media. These cultures were evaluated at incubation times of 24, 48, 72 and 96 hours. In most of strains analyzed wasn’t showed significant difference in the growth rate comparing TYSGM-9 and Pavlova media (Wilcoxon p&gt;0.016). In Pavlova medium, the trophozoites showed a maximum growth at 72 hours with significant difference when compared with the times of 24 h and 96 h (Wilcoxon &lt;0.008). In LES, viable trophozoites were observed until 24 hours, with a significant difference (Friedman p&lt;0.05, Wilcoxon p&lt;0.016) in the number of parasite cells compared with Pavlova and TYSGM-9 media cultures. Thus, LES medium seemed to be less adequate than the other media for maintenance of B. coli. Despite the satisfactory results in TYSGM-9, Pavlova medium was considered ideal for the maintenance of this protozoan strain, guaranteeing the viability of the parasite with subculture every three days, presenting lower costs.
