title: Accuracy of the Kriging Error Estimate Through Cross Validation

description: ABSTRACT Cross-validation (CV) is used for error checking in kriging estimates. To quantify the error of a CV, 1875 eucalyptus trees were rigorously planted. A volume/tree map was constructed by kriging, generating 8736 points. Samples with different sizes (100, 150, 200, 250, 300 and 350) were taken from the 8736 points through systematic and random sampling and volume maps were constructed by kriging. A straight line was fitted to Estimated x Observed graph. The R2, the intercept and the slope were the errors parameters. The CV did not provide reliable results for the R2 in the systematic sampling with 100, 150, 200 and 250 samples, but it was reliable for the R2 in all randomized trials. The systematic sampling had good real results, R2 &gt; 0.70 with 200 samples, while random sampling showed R2 &gt; 0.70 only with 250 samples.

title: Relationship between cognitive processing, language and verbal fluency among elderly individuals

description: ABSTRACT Some cognitive dimensions, such as attention, memory and executive functions, may decline with age, while other functions remain intact or even improve due to greater life experience. Objective: to analyze the relationship between cognitive processing, language and verbal fluency among elderly individuals seen by primary healthcare services located in a city in the interior of São Paulo, Brazil. Methods: a cross-sectional study with a quantitative method was conducted. A total of 149 elderly individuals were assessed through previously scheduled interviews. Data collection included a questionnaire on sociodemographic data and the Addenbrooke's Cognitive Examination - Revised (ACE-R). Cognitive processing (P300) was assessed using a device that captures potentials elicited in auditory tasks. Descriptive analysis and Spearman's correlation were performed with the level of significance established at 5%. Results: a negative correlation was found between language and P300 latency, while a positive correlation was found between verbal fluency and P300 amplitude. Comprehension and naming tasks showed a negative correlation with latency. The repetition task revealed a positive correlation with P300 amplitude. Conclusion: although more extensive testing is needed, these findings suggest that language correlates with P300 latency, whereas verbal fluency correlates with P300 amplitude.

title: Neuropsychiatric symptoms and executive function impairments in Alzheimer’s disease and vascular dementia: The role of subcortical circuits

description: ABSTRACT Neuropsychiatric symptoms (NPS) in dementia are prevalent, under-recognized and little studied regarding their pathophysiological aspects. The pathophysiological mechanism, as well as the possible role of vascular lesions in the genesis of these symptoms, are still matters of debate. Objective: to describe and compare the prevalence and severity of NPS in subjects with Alzheimer's disease (AD) and vascular dementia (VaD). Methods: a cross-sectional study involving 82 outpatients, divided into two groups (AD × VaD), was conducted. Patients were submitted to the Cambridge Cognitive Test (CAMCOG), the Clock Drawing Test (CLOX 1 and 2), the Neuropsychiatric Inventory (NPI) and the Clinical Dementia Rating (CDR) scale. Neuroimaging was scored using the de Leon and Fazekas scales. Results: 90.8% of the patients had at least one neuropsychiatric symptom. There were statistical differences on the CLOX test and in the apathy symptoms between AD and VaD groups. Apathy and disinhibition proved more prevalent in patients with higher vascular load. Conclusion: apathy and impaired executive function may reflect vascular damage in subcortical circuits in dementia patients.

title: Quality of Plywood Panels Made with Wood Veneer of Three Eucalyptus Species

description: ABSTRACT The quality of plywood produced with wood veneer of Eucalyptus saligna, Eucalyptus dunnii and Eucalyptus urophylla x Eucalyptus grandis hybrid in different compositions was analyzed. Seven-layer veneer panels measuring 500 × 500 × 14 mm, glued with phenol-formaldehyde (PF), weighing 360 g. m-2 in double line and with 28 or 32% of solid content were produced. Panels were pressed under 130 °C and 12 kgf. cm-2, during 15 minutes. We analyzed the properties of specific gravity, moisture content, water absorption, thickness swelling, glue line shear and static bending. The results were compared to the requirements of the ABIMCI technical catalog and EN 314-2 and DIN 68 792 standards. Eucalyptus dunnii panels presented lower values of mechanical properties, with an upward trend when in mixtures. The panels produced with Eucalyptus saligna and the Eucalyptus urophylla x Eucalyptus grandis hybrid showed good results, either pure or mixed with the other species.

title: Urban expansion of the metropolitan region of Belém from the perspective of a sustainability index system

description: Abstract The metropolitan area of Belém (RMB) contains 1/3 of the population of Pará State, Brazil, and its recent expansion has caused a number of social and environmental problems that undermine access to infrastructure and services and also impact other factors that influence urban sustainability. In recent years, various methodologies for assessing the sustainability of cities have been proposed, but the challenges of incorporating a multidimensional approach in the evaluation of urban sustainability are still enormous. In this work, we applied the Urban Sustainability Index System (SISU) to the RMB in order to analyze the levels of sustainability of the municipalities that constitute this metropolitan area and to verify the limitations and challenges in applying this method of measurement in the Amazon region. Seven indicators were used for the environmental quality index (IQA), and four for the political institutional capacity index (ICP) and the municipal human development index (IDHM). The results show that there is little variation in the IQA and IHDM indices, and the least-populated municipalities such as Santa Barbara and Benevides have better IQAs, while larger-populated municipalities, such as Belém and Ananindeua, have better IDHMs. However, it is in relation to ICP that this metropolitan area has the highest inequality, thus reflecting the need for the institutional and political empowerment of this region.

title: Effectiveness of photodynamic therapy on Candida species isolated from oral samples of children exposed and not exposed to HIV

description: ABSTRACT Objective: Identify yeast species isolated from unexposed, exposed and HIV-carrier children, and verify the effectiveness of low power laser photodynamic therapy (PDT) on the yeasts species belonging to the Candida genus. Methods: Fifty children assisted by the Public Health Program of the city of Vitória da Conquista, Bahia, were selected and divided into three groups: unexposed to HIV, exposed to HIV during pregnancy, and HIV-carrier. Saliva samples were collected in a disposable sterile universal container and were plated to Sabouraud dextrose agar supplemented with 0.1 mg/mL chloramphenicol. The plates were incubated at 37°C for 48 h. Three strains of each patient were identified by using an API 20 C AUX system. The strains were submitted to photodynamic therapy (PDT) with a 660 nm low power laser and methylene blue dye at different times of irradiation (90, 180 and 282 sec.). Results: The results showed that the most prevalent species was Candida albicans followed by Candida famata (second most prevalent in unexposed to HIV and HIV carriers)) and Candida parapsilosis (second most prevalent in exposed to HIV group). The CFU/mL of Candida spp. decreased significantly (p&lt;0,05) in all groups treated with PDT compared to the controls. Photodynamic therapy treatments at different exposure times (e.g., PS+L90+, PS+L180+, PS+L282+) revealed that the exposure time of 282 sec. gave the highest reduction of the mean logarithmic CFU/mL. Conclusion: Candida albicans was the most prevalent Candida species in these three groups and Candida non-albicans species, when combined, amounted to a significant percentage of Candida isolates. Photodynamic therapy was effective in inactivating the Candida spp. isolated from the oral cavity of children not exposed to HIV, exposed to HIV and HIV-carriers, with the best photodynamic therapy irradiation time being 282 sec.

title: Viral and bacterial contamination in groundwater from the Guaraní Aquifer’s recharge area, Ivoti municipality, RS

description: Abstract The water supply of the municipality of Ivoti comes solely from an underground source. The potability of groundwater in the municipality was evaluated by analyzing bacterial (Escherichia coli and total coliforms) and viral (adenovirus, enterovirus and rotavirus) markers for contamination. Twenty-seven water samples from artesian wells, dug wells and springs were collected between February and April 2011. The determination of the most probable number (MPN) of E. coli and total coliforms in 100 mL was performed by the multiple-tube method. Viral markers were analyzed in 500 mL aliquots by polymerase chain reaction (PCR). Total coliforms were found in 66.6% of samples. Contamination found for E. coli was 25.9%, 40.7% for adenovirus and 22.2% for rotavirus. Enterovirus was not found. The presence of coliform bacteria and viruses in the samples indicates fecal contamination of groundwater at the study site, located in the recharge portion of the Guarani Aquifer and suggests the need of caution regarding the use of these water sources for public water supply, individual water catchment and farming.

title: Curiosity as Brazilian tourist motivation in visiting Europe

description: Abstract Although the theme of push and pull motivations has received increasing attention in tourist behavior literature, little attention has been devoted to the investigation of the interaction between single push motivations and visitor loyalty and other relevant variables influencing tourist behavior. Given its undoubtable relevance in motivating human behavior, we propose curiosity as a single push motive by examining its causal relationships with destination attributes (evaluated in holistic way), attitude toward destination, and loyalty. In particular, we tested a new research model on a sample of 273 potential Brazilian travelers to Europe by using a structural equation modeling approach. Sample size is in line with the state-of-the-art in literature (Ciasullo et al., 2017). The data moderately well fitted the “curiosity model” and the findings highlighted that curiosity plays a crucial role in shaping attitude and pull motivation, and in influencing tourist loyalty. Consequently, destination managers or European Union institutions should magnify the role of curiosity, attitude towards destination, and pull motivations in terms of marketing policies.

title: The effect of drying temperatures and storage of seeds on the growth of soybean seedlings

description: Abstract: Drying of seeds reduces their moisture content to levels appropriate for storage. However, care in the temperatures applied in the process is necessary to avoid damage to the seeds that are dried. The aim of this study was to evaluate the effect of different drying temperatures and storage on the growth of soybean seedlings. Harvested with a moisture content of approximately 23% (w.b.), the seeds were dried at different temperatures (40, 50, 60, 70, and 80 °C) until reaching moisture content of 12.5 ± 0.7% (w.b.), and they were subsequently stored for 180 days in an environment without climate control. A germination test and evaluations of seedling performance were carried out every 45 days, determining the full length of the seedling and hypocotyl and root lengths, along with their respective dry matter weights. The results showed that: a) the increase in the temperature of drying air affects the physiological quality of soybean seeds, and this effect is accentuated over time, especially on root length; and b) the air temperature of 40 °C can be recommended for drying of soybean seeds in association with the storage time of 180 days under storage conditions without climate control.

title: Ethical problems identified by nurses in relation to patients in critical condition

description: This article presents an identification and analysis of ethical issues identified by nurses in relation to patients in a critical condition, who are at imminent risk of death and whose survival depends on advanced means of surveillance, monitoring and therapy. The main ethical concerns are providing information to the client, end of life monitoring, professional liability in interdependent interventions; themes related to the decisions of the patient (consent to/refusal of therapeutic treatment), information dilemmas, action to be taken during the processes of dying and with regard to do not resuscitate orders, and respect for human rights in unfavorable situations. The present study considers the importance of a sense of responsibility and of protecting the individual at risk, the influence of moral conscience in decision-making, and professional experiences when overcoming challenges. Finally, mediating factors in the management of ethical difficulties are identified.
