title: Effect of stocking density on the growth and survival of Anomalocardia brasiliana (Gmelin, 1791) (Bivalvia: Veneridae) post-larvae

description: ABSTRACT: Anomalocardia brasiliana post-larvae were cultured for 28 days to evaluate the effect of stocking density on their growth and survival rate. Three stocking densities were tested 40, 80 and 160 post-larvae cm-2, in experimental units (2-L) with static cultivation system and total water renewal at each 48 hours. The experimental design was completely randomized with three treatments and three repetitions each. Stocking density of 40 post-larvae cm-2 reached 1 mm length within 24 days, while only 18% of the post-larvae at density of 80 post-larvae cm-2 reached 1 mm length in the same time. The density of 40 post-larvae cm-2 had the highest specific growth rate, 4.98±0.08% day-1. The survival rates of post-larvae at lower densities were significantly higher (53.24±4.60% and 52.95±3.32%, on 40 and 80 post-larvae cm-2, respectively) compared to higher stocking density (31.54±0.70%). In the cultivation of A. brasiliana post-larvae, stocking density must be managed during growth. The density of 160 post-larvae cm-2 can only be used until the post-larvae reach 600μm in length, then they should be at 40 post-larvae cm-2 density to keep the maximum daily growth rate.

title: Domestic violence against elderly people assisted in primary care

description: ABSTRACT This article aims to investigate the prevalence of domestic violence against elderly people in primary care and possible associated factors. A descriptive, cross-sectional study, with 169 individuals aged 60 years and over, of both sexes, enrolled in the Family Health Units (FHU) of the 4.1 micro region of the city of Recife. Elderly people with health impairment that compromised communication and/or cognition were excluded. The data were collected through interviews in the homes or FHU, with socio-demographic issues, self-perceived health and the research instrument to evaluate possible situations of violence, which was developed and validated in Puerto Rico and adopted by the Ministry of Health. There were 133 elderly people with indicative signs of at least one type of violence in their domestic environment, representing a prevalence of 78.7%, with negligence as the most prevalent type (58.5%), followed by psychological (21.5%) and financial (14%). The elderly interviewed who classified their health as regular/poor have this increased risk. The study reinforces the hypothesis of the existence of domestic violence against the elderly. Thus, identifying its prevalence is the first step in addressing this public health problem.

title: The Workers’ Mental Health Care Project of Universidade Federal do Rio de Janeiro - Prasmet: 20 years

description: Abstract Introduction: the Workers’ Mental Health Care Project (Prasmet), conducted by the Universidade Federal do Rio de Janeiro, is as a concentrated effort in the Worker’s Health field to produce knowledge on mental health and work, providing a psychosocial clinic to the workers of one of the largest Brazilian universities. Objectives: to present the history of Prasmet, and to describe the occupational health interventions focused on the university workers. Methods: two axes were described - the first explaining Prasmet actions; and the second about the construction of patients’ profile, based on information about the attention provided to the workers and the clinical characteristics of this population. Results: clinical practice focused on workers’ activities allows health problems to be spatially, temporally and socially contextualized, such as the prevalence of the depression diagnosis group, and of workers with higher risk of illness, as the nursing group. Conclusion: the development of strategies for promotion, rehabilitation and education in occupational health allows institutional approaches of greater magnitude and resolution.

title: Titanium dioxide (TiO2) as a marker to estimate fecal output in sheep

description: ABSTRACT: Titanium dioxide (TiO2) is an external marker used to estimate fecal output based on forage intake of grazing ruminants; however, its use as marker for grazing sheep still needs attention. In the present study the TiO2 role to estimate fecal output of sheep grazing annual ryegrass was tested. Two essays were conducted in sequence using the same forage and animals. Six lacaune lambs were housed in metabolic cages. Lambs were administered 1 g TiO2 in a single (at 8:30 am, essay 1), or in two daily doses (at 8:30 am and 4:30 pm, essay 2). In both essays the TiO2 administration was followed by a 7-day period to stabilize the fecal excretion of the marker and then by a 5-day period for total collection of feces. Observed and TiO2-based estimated fecal outputs were compared, with or without correction for TiO2 fecal recovery rate (kTiO2). The kTiO2 was around 1.0 and the estimated fecal outputs were similar to the observed ones (p&gt;0.05), regardless the number of daily doses. These results suggested that TiO2, administered in single or two daily doses, can be used as an external marker in grazing sheep.

title: Study of Structural and Electric Properties of the PZT 52/48 Doped With Er+3

description: The scientific community has shown a growing interest in relating to the ferroelectric materials and it has made an effort to develop them. Among these several ferroelectric materials, we proposed to investigated Pb(ZrTi)O3 doped with distinct Er+3 concentrations. Our aim was to investigate how the erbium affects the PZT electrical properties. To determine the ideal sintering temperature of our ceramic samples, the dilatometry tests were performed. These results have showed that the erbium caused a change in sample densities (91.9% &lt; ρ &lt; 99.0%) as compared to undoped PZT sample. Furthermore, the X-ray diffraction results indicated that all samples are monophasic and peaks are indexed to tetragonal crystalline structure. According to these also results, there was an increment of the parameter a and a reduction of parameter c as compared to undoped PZT sample. On the other hand, the average grain size have decreased with the increment of erbium content. The electrical characterization of ours ceramics showed a peculiar ferrelectric-paraeletric phase transition around 390 ºC. Finally, the ferroelectric hysteresis measurements for doped samples in site A have revealed that remnant polarization and coercive field values depend on content. Whereas, doped samples in site B, the corresponding values are similar.

title: Care to the bereaved family: a necessary public action

description: ABSTRACT The mourning process is unique, and develops according to the characteristics of the mourner and the circumstances of death, increasingly growing in hospitals. There are many difficulties in coping with mourning, therefore, it is important to offer care to bereaved families. This study reports and analyzes the repercussions of interventions offered by a public hospital in the interior of São Paulo, through qualitative research, with a comprehensive approach, based on sociological phenomenology. A semi-structured interview was carried out, and the collected material was submitted to content analysis. The bereaved relatives showed difficulty in facing such period, and, even in the face of foreseeable deaths, there is the need of a space for them to be heard and understood. The study confirms the benefit of bereavement care to be performed by the hospital staff, because this contact in the post-mortem period of the user provides a feeling of comfort to the family in the face of the incident.

title: Effect of laser treatment on postural control parameters in patients with chronic nonspecific low back pain: a randomized placebo-controlled trial

description: The management of nonspecific lumbar pain (NSLP) using laser irradiation remains controversial. A systematic review of recently published studies indicates that the effects of laser therapy are commonly assessed using only imperfect methods in terms of measurement error. The main objective of this study was to assess static postural stability using an objective tool in patients with chronic NSLP after laser irradiation at different doses and wavelengths. In total, 68 patients were included in the laser sessions and were randomly assigned into four groups: high-intensity laser therapy at 1064 nm and 60 J/cm2 for 10 min (HILT), sham (HILT placebo), low-level laser therapy at 785 nm and 8 J/cm2 for 8 min (LLLT), and sham (LLLT placebo). In addition, all patients were supplemented with physical exercises (standard stabilization training). To assess postural stability, a double-plate stabilometric platform was used. All measurements were performed pre- and post-laser sessions (three weeks) and at follow-up time points (one and three months). Laser procedures led to more balanced posture stability in patients, although these positive changes were significant mainly for short-term observation (after 4-week therapy). In the follow-up analysis, the parameters were gradually impaired. Kruskal-Wallis analysis of variance (ANOVA) for independent variables did not show any difference between the studied groups. Low- and high-intensity laser therapy does not lead to a significant improvement in postural sway in patients with NSLP compared with standard stabilization training based on short- and long-term observations.

title: Growth and physiology of maize under water salinity and nitrogen fertilization in two soils

description: ABSTRACT The nitrogen fertilization, in general, minimizes the effects of salinity on plants, but the mitigating action depends on plant species, cultivar, soil texture and plant age, among other factors. The objective of this study was to evaluate the effects of irrigation water salinity and nitrogen fertilization on maize physiology and growth (Zea mays) in soils with different textures. The experiment was carried out in a greenhouse in Fortaleza City, CE, Brazil, in PVC soil columns (100 x 20 cm). The design was completely randomized using the factorial 2 x 2 x 4, referring to two soils, an Ultisol and a Quartzipsamment, nitrogen doses of 105 and 210 kg ha-1, under irrigation with saline water of 0.5, 2.0, 4.0 and 6.0 dS m-1, with four repetitions. With the exception of stem diameter, salinity of water impaired plant growth and leaf gas exchanges. The Ultisol provided better growth and physiological responses compared to the Quartzipsamment. The nitrogen doses did not mitigate growth variables except root biomass. The gas exchanges increased with the highest nitrogen dose, without interaction with the salinity.

title: Nb-Al Binary System: Reevaluation of the Solubility Limits of the (Nb), Nb3Al, Nb2Al and NbAl3 Phases at High Temperatures

description: In this work a re-investigation of the solubility limits of the (Nb), Nb3Al, Nb2Al and the Nb-rich side of the NbAl3 phases on the Nb-Al system is presented. Alloys in the binary fields ((Nb)+Nb3Al, Nb3Al+Nb2Al and Nb2Al+NbAl3) were arc-melted, and then equilibrated at 1000, 1200 and 1400 ºC. The phases were confirmed via X-ray powder diffractometry, and their compositions were determined via EPMA measurements. The results showed agreement with the literature concerning the solubility limits of (Nb), Nb3Al and NbAl3 phases, while important differences in the values were found for the Nb2Al phase. In addition, the lattice parameters of the Nb2Al phase were determined via Rietveld refinement. This new set of more accurate experimental information indicates that a thermodynamic reassessment is necessary to precisely describe this system.

title: Theoretical and experimental evaluation of compressive strength of concretes through nondestructive tests

description: ABSTRACT When evaluating degraded structures, it’s common the need to determine mechanical properties of concrete structures with no project data. Properties such as compressive strength and modulus of elasticity, for example, are significant in this analysis. However, although it’s possible to extract concrete samples for laboratory evaluations of parameters of interest, from the theoretical point of view, this is not always achievable when dealing with field activities, due to time limitations, budget restraints or even the structural restrictions from the element itself. In this sense, the preference for nondestructive methods is a possibility which provides, with reasonable accuracy, the needed information regarding the required mechanical properties. It’s possible to find in the literature mathematical expressions that directly correlate sclerometrical index (or rebound index) and the ultrasonic pulse velocity to compressive strength and to the elastic modulus. Therefore, this work compared the theoretical results to the experimental ones, obtained through 26 specimens from the concrete used in Grande Vitoria, with different compositions and ages, based on this materials’ compressive strength. Thus, this study’s conclusions verified the existence of a correlation among the results obtained from nondestructive and experimental tests.

title: Eustrongylides sp. (Nematoda, Dioctophymatoidea) parasitizing Hoplias malabaricus (Actinopterygii: Erythrinidae) collected from the state of Rio de Janeiro, Brazil

description: Abstract Hoplias malabaricus (Characiformes, Erythrinidae), trahira, is a neotropical freshwater fish of economic and public health significance. A total of 45 specimens of H. malabaricus commercialized in the municipality of Magé, state of Rio de Janeiro, Brazil, were acquired between April 2016 and April 2018 to investigate the presence of nematode larvae. Twenty of the fish were found parasitized by 347 fourth-stage nematode larvae identified taxonomically as Eustrongylides sp. using morphological, morphometric and molecular data. The parasitic indices were: prevalence 44.44%, mean intensity 17.35, mean abundance 7.71, and range of infection 2-40. Infection sites were musculature, mesentery, abdominal cavity, and serosa of intestine, stomach and liver. This is the first report of Eustrongylides sp. larvae parasitizing H. malabaricus in the state of Rio de Janeiro.
