title: Quad-Band Printed Antenna for Portable WLAN Applications

description: Abstract This paper presents a novel printed monopole antenna for quad-band operation in four WLAN bands: ISM 2.4 GHz, 5.2 GHz, 5.6 GHz, and ISM 5.8 GHz. This antenna is compact, thin, lightweight, easy to manufacture, and suitable for portable devices. It is composed of a folded strip radiator and two parasitic strips printed on a partially grounded substrate. The folded strip radiator interacts with the parasitic strips, which are connected to the ground plane, in such a way as to produce the resonant modes that originate the radiation bands of the antenna. An additional open-ended strip connected to the radiator is used to adjust the antenna input impedance in the upper operation band. A parametric study on several geometrical dimensions of the antenna is carried out in order to analyze their influence on the antenna performance. The fabricated prototype of the proposed printed monopole antenna has overall dimensions of 22 × 48 × 1.6 mm3, and the measured 10-dB return-loss bands exhibited by the antenna are 2149-2660 MHz and 5120-6035 MHz.

title: In search of a lost treasure: cultural mapping studies in the field of Political Science and International Relations in Brazil

description: Abstract We investigate how the theme of “culture” has been studied in Political Science and International Relations (PSIR) in Brazilian academia from 1990 to 2017. A “systematic literature review” was conducted, assessing 183 online articles. The data collected suggests differences between PS and IR, a lack of methodology, and some degree of causality between institutions, authors, and the research approach adopted in the articles.

title: Antibacterial and cytotoxicity activities and phytochemical analysis of three ornamental plants grown in Mexico

description: Abstract: This study evaluates the antibacterial, cytotoxic activities, and phytochemical composition, of Callistemon citrinus, Hibiscus rosa-sinensis and Plumbago auriculata leaves and flowers, three ornamental plants in Mexico. However, in other countries offers a range of other uses. Ethanol extracts of C. citrinus leaf and flower presented stronger antibacterial activity than the extracts obtained from the other two plants. C. citrinus leaf showed low cytotoxicity (LC50 &lt;600 µg/mL) on the brine shrimp test, whereas the ethanol extracts of H. rosa-sinensis and P. auriculata leaves showed no cytotoxic activity. Flower extracts obtained from the three plants did no exhibit cytotoxicity. GC-MS analysis revealed that the ethanol extract of P. auriculata leaf contained lupeol triterpene and lupeol acetate, neither of them have been previously reported in this genus. Gamma sitosterol was present in the leaf and flower extracts of P. auriculata. Higher contents of linoleic and linolenic acids were found in extracts of H. rosa-sinensis leaves and flowers. The ability of the ethanol extracts of C. citrinus leaves and flowers to inhibit the growth of Gram-positive and Gram-negative bacteria indicates a potentially broad antimicrobial spectrum. Moreover, the absence of cytotoxicity suggests the potential use of this plant to treat microbial infections.

title: Correlation of Cervical Cancer Mortality with Fertility, Access to Health Care and Socioeconomic Indicators

description: Abstract Objective The present study aimed to examine which development indicators are correlated with cervical cancer (CC) mortality rates in Brazil. Methods This was an ecological study that correlatedmortality rates and indicators, such as human development index (HDI), gross domestic product (GDP) per capita, illiteracy rate, fertility rate, screening coverage, proportion of private health insurance use, density of physicians, and density of radiotherapy centers. Themortality rateswere obtained fromthe Brazilian national registry, while the indicators were based on official reports from the Ministry of Health. Univariate and multivariate linear regression was used. Results Among the states of Brazil, the average age-specific CC mortality rate from 2008 to 2012 varied from 4.6 to 22.9 per 100,000 women/year. In the univariate analysis, HDI, proportion of private health insurance use, density of physicians, and density of radiotherapy centers were inversely correlated with the mortality rates. Fertility rate was positively correlated with the mortality rates. In the multivariate analysis, only fertility rate was significantly associated with the CC mortality rate (coefficient of correlation: 9.38; 95% confidence interval [CI]: 5.16-13.59). Conclusion A decrease in the fertility rate, as expected when the level of development of the regions increases, is related to a decrease in the mortality rate of CC. The results of the present study can help to better monitor the quality assessment of CC programs both among and within countries.

title: Luiz Nunes and the plan for health institutions in Pernambuco

description: Abstract During Pernambuco governor Carlos Lima Cavalcanti’s term (1930-1937), the architect Luiz Nunes and his team were able to produce a series of plans for notable public buildings in the short period of time spanning 1934 to 1937. This article analyzes plans for the School for Abnormal Children and the Military Brigade Hospital, which exemplify the close relationship between medical knowledge, modern architecture, and state government policy and have not yet been examined in detail in academic studies. The main sources were the archives of the Diário da Manhã and Diário de Pernambuco newspapers, as well as the group of architectural plans in the Jordão Emerenciano Public Archive.

title: Environmental fragility and vegetation cover dynamics in the Lapa Grande State Park, MG, Brazil

description: Abstract: The environmental fragility analysis evaluates the susceptibility of an environment to degradation. Thus, the goals of this work are to analyze and map the environmental fragility of the Lapa Grande State Park (PELG), Brazil, and its buffer zone (ZA) and also quantify the changes in the vegetation cover before and after the implementation of the PELG. The environmental fragility was evaluated through multicriteria analysis using the factors: slope, geology, pedology and land use and land cover. The changes in the high vigor vegetation cover were determined from the normalized difference vegetation index (NDVI) for 1996, 2006 and 2016. It was verified that the central-east and northeast regions of the PELG presented the greatest environmental fragilities in 1996, and significant reductions in the areas with high and very high fragility were observed in 2006 and 2016 due to the increase in the vegetation cover after the implementation of the PELG, which was more expressive in the park area than in the ZA. The increase of 20.7% of 2006 to 2016 in the vegetation with greater vigor, proved the importance of the creation of a conservation unit.

title: Generation of Non-diffraction Vortex Beam and Its Application in Digital Communication

description: Abstract An axicon-frustum basin-type Bessel resonator is designed for generating non-diffraction vortex beams with opposite propagation directions under different conditions. Based on the theory of geometric optics, the principle of creating vortex beams is analyzed in this axicon-frustum basin-shaped resonant cavity. It is shown that a non-diffraction vortex beam can be produced in the cavity under high-order beam stimulation. In the terahertz wavebands, the dyadic Greens function algorithm is used to numerically evaluate the electromagnetic characteristics in the cavity, and the numerical results demonstrate that the conclusion of the principle analysis is valid. Finally, the application of nondiffraction vortex beams in digital communication is explored.

title: FUZZY MODELING OF THE EFFECTS OF IRRIGATION AND WATER SALINITY IN HARVEST POINT OF TOMATO CROP. PART II: APPLICATION AND INTERPRETATION

description: ABSTRACT Tomato, the most popular greenery, is characterized by being a demanding crop in water and when in prolonged and severe drought, has limitations in its growth and reduction in productivity. In addition, this vegetable is affected by excess salinity in the water, which causes leaf wilting, apex and leaf edges burn until their death. Such effects generally are studied using statistical analysis, but there are mathematical theories that allow finer adjustments, highlighting among them, the fuzzy logic. The objective of this study was to evaluate the effects on the growth and yield of hybrid tomato from different water tensions in the soil and different salinity doses in the irrigation at 120 days after sowing using fuzzy modeling. It was used data from an experiment that was conducted in the experimental area at the School of Agriculture of São Paulo State University (UNESP) in Botucatu-SP. The input variables of the fuzzy systems were irrigation and salinity, while the output variables elected were the biometric analysis and productivity that showed statistically significant differences. Analyses of the effects of irrigation and salinity were performed by means of three-dimensional graphics and the output variables contour maps. The variables studied here showed higher values, with exception of plant height for treatment with irrigation in field capacity and water salinity zero.

title: BOVINE WELLFARE HANDLED IN ADAPTED CORRAL WITH UNCONVENTIONAL MATERIALS

description: ABSTRACT This study aimed at evaluating bovine behavioral parameters managed in crowding pens built with modular panel of reforestation wood and homogeneous particle sheets of sugarcane bagasse and in conventional wooden crowding pens. The animals treated had their body surface temperature measured by the infrared thermography method and the behavior evaluated through the flight time parameters and the behavior score in the crowding pens. The results indicated that the animals managed in these buildings showed no difference in the behavioral parameters, but the mean and maximum superficial body temperatures were lower in the animals managed in the crowding pens of modular panel.

title: Resilience levels among adolescents with ADHD using quantitative measures in a family-design study

description: Abstract Objectives To investigate resilience levels in adolescents with attention-deficit hyperactivity disorder (ADHD) using quantitative measures when compared to their non-affected siblings and controls. We also aimed to investigate the correlation between resilience and depression, anxiety, intelligence quotient (IQ) and socioeconomic status, which may affect resilience levels and be potential confounders. Methods Adolescents (n=45) diagnosed with ADHD referred to an outpatient ADHD clinic, and their siblings without ADHD (n=27), with ages ranging from 12 to 17 years, were interviewed along with their parents using a semi-structured interview (Children’s Interview for Psychiatric Syndromes - Parent Version). Intelligence was measured with the Block Design and Vocabulary subtests from the Wechsler Battery. Anxiety and depression were investigated using the Children State-Trait Anxiety Inventory (CSTAI) and the Child Depression Inventory (CDI), respectively. Resilience was investigated using the Resilience Scale. A control group (typically developing adolescents [TDA] and their siblings; n=39) was recruited in another outpatient facility and at two schools using the same methodology. Results Socioeconomic status and intelligence levels, which may affect resilience, were similar in all groups. Adolescents with ADHD showed lower resilience levels compared to siblings and TDA even when controlled for anxiety and depression levels, which were higher in ADHD. Resilience levels were higher in siblings than in adolescents with ADHD, and lower than in TDA – this last result without statistical significance. Conclusion In our sample, ADHD in adolescents was associated with lower resilience, even when controlled for confounders often seen in association with the disorder.

title: Primary Mediastinal Hydatid Cyst Causing Diaphragmatic Palsy

description: Abstract Hydatid cystic disease is a significant clinical problem in endemic countries. Hydatid cysts are most commonly located in the liver and lungs. Primary mediastinal hydatid cyst is a rare clinical entity. The diagnosis must be considered in a patient with a mediastinal mass, particularly in endemic regions. Mediastinal hydatid cysts causing paralysis of phrenic and recurrent laryngeal nerves have been rarely reported. We describe a rare case of primary mediastinal hydatid cyst associated with diaphragmatic palsy caused by compression of the left phrenic nerve, which was successfully treated with partial cystectomy and capitonnage with hemidiaphragmatic plication.

title: Schizophrenia TreAtment with electRic Transcranial Stimulation (STARTS): design, rationale and objectives of a randomized, double-blinded, sham-controlled trial

description: Abstract Introduction Schizophrenia is a severe mental disorder. While some antipsychotic medications have demonstrated efficacy in treating positive symptoms, there is no widely recognized treatment for negative symptoms, which can cause significant distress and impairment for patients with schizophrenia. Here we describe the rationale and design of the STARTS study (Schizophrenia TreAtment with electRic Transcranial Stimulation), a clinical trial aimed to test the efficacy of a non-pharmacological treatment known as transcranial direct current stimulation (tDCS) for treating the negative symptoms of schizophrenia Methods The STARTS study is designed as a randomized, sham-controlled, double-blinded trial evaluating tDCS for the treatment of the negative symptoms of schizophrenia. One-hundred patients will be enrolled and submitted to 10 tDCS sessions over the left dorsolateral prefrontal cortex (anodal stimulation) and left temporoparietal junction (cathodal stimulation) over 5 consecutive days. Participants will be assessed using clinical and neuropsychological tests before and after the intervention. The primary outcome is change in the Positive and Negative Syndrome Scale (PANSS) negative subscale score over time and across groups. Biological markers, including blood neurotrophins and interleukins, genetic polymorphisms, and motor cortical excitability, will also be assessed. Results The clinical results will provide insights about tDCS as a treatment for the negative symptoms of schizophrenia, and the biomarker investigation will contribute towards an improved understanding of the tDCS mechanisms of action. Conclusion Our results could introduce a novel therapeutic technique for the negative symptoms of schizophrenia. Clinical trial registration: ClinicalTrials.gov, NCT02535676 .
