Assessment of Indoor Radon Levels in Brazil: an overview

Radon is a naturally occurring, tasteless, odorless and colorless radioactive gas at room temperature, it can diffuse into the environment through soil, water (mineral or thermal or groundwater) and buildings. In poorly ventilated environments, such as homes, it can accumulate at levels that are harmful to humans and therefore pose risks to public health. In Brazil, research involving indoor radon dates back to the late 1980s. There is still no specific legislation for radon, but the Ministry of Health recommends an alpha radiation limit value of 0.1 Bq m and 1.0 Bq m for beta radiation. The present study aimed to explore the state of the art of research on natural radioactivity resulting from radon in Brazil through a survey of articles published in the Scopus database. A total of 67 research articles were considered for this purpose.
Developmental exposure to methylmercury and ADHD, a literature review of epigenetic studies

Abstract Attention-deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects the competence of academic performance and social wellness in children and adults. The causes of ADHD are unclear. Both genetic and environmental factors contribute to the development of ADHD. The behavioral impairments in ADHD are associated with epigenetic changes in genes that are important for neurodevelopment. Among environmental causes of ADHD, the neurotoxin methylmercury (MeHg) is associated with an increased risk for ADHD. Developing children are susceptible to neurotoxic effects of prenatal MeHg exposure. Human epidemiology studies have shown that prenatal MeHg exposure could invoke epigenetic changes in genes that are involved in ADHD. In addition, the pathogenesis of ADHD involves dopaminergic system, which is a target of developmental MeHg exposure. MeHg-induced alterations in the dopaminergic system have a profound impact on behavioral functions in adults. As a trace level of MeHg (around nM) can induce long-lasting behavioral alterations, potential mechanisms of MeHg-induced functional changes in the dopaminergic system may involve epigenetic mechanisms. Here, we review the relevant evidence on developmental MeHg exposures and the risk for ADHD. We also point out research gaps in understanding environmental causes of ADHD.
Faults detection by finite element analysis of a multi cracked beam using vibration signatures

In this paper, analysis for fault identification in a cracked beam has been carried out. Theoretical, finite element and experimental analyses for identification of the crack depths and their positions in a beam containing multiple transverse cracks are carried out. It has been established that a crack in a beam has an important effect on its dynamic behaviour. The strain energy density function is used to evaluate the additional flexibility produced due to the presence of crack. Based on the flexibility, a new stiffness matrix is deduced and subsequently that is used to calculate the natural frequencies and mode shapes of the cracked beam. The analysis of the crack structure is done using theoretical, finite element and experimental analysis. The results from finite element method and experimental method are compared with the results from the numerical analysis for validation. The results are found to be in good agreement.
A COMPARISON STUDY ON MICRO-BULGING AND SHORTLESS PEENING PROCESSES USING WATER JET CAVITATION

This paper presents a comparative study using a newly technology called water jets cavitation to fabricate micro feature on 304 stainless steel foils with a thickness of 100 µm and surface enhancement of 8090AlLi alloy sample with a thickness of 4 mm, where angular nozzle and a designed cavitation system were used with an incident pressure of 8-20 MPa. The bulged sample and the effect of incident pressure on the cavitation zone range were investigated. The experimental results indicated that the formed sample bulging depth of the outer ring shock zone and the bulging depth of the jet shock zone were not ideal, while the pits in the cavitation shock zone (that is, pits 2~4 and 10~12) obtained good geometric characteristics. Finally, the consistency of the maximum bulging depth was relatively good. The micro-bulged parts showed that the micro-pits in the cavitation shock zone had a large bulging depth and their uniformity was relatively good, indicating that the circular array feature micro-die has good performance in the cavitation water jet shock micro-bulging process. The effect of incident pressure on the range of cavitation zone, also indicated that the effective area of action of the cavitation water jet showed a ring. That is when the incident pressure was 20 MPa with a target distance of 120 mm, the maximum cavitation shock (bulging) zone showed rings of 3.5 ～21.1 mm with the 304 stainless steel foil and 3.5 mm~21.4 mm also with the 8090Al-Li alloy plate which were approximately same.
Control of Brevicoryne brassicae (Hemiptera: Aphididae) with extracts of Agave americana var. Marginata Trel. in Brassicae oleraceae crops: management system

Email: adalgisa.pereira@gmail.com Alternative methods of pest control can and should be encouraged, especially those that consider the reality of smallholder family farmers. Here, we evaluated the potential of Agave americana (agave) extracts for the control of the aphid Brevicoryne brassicae in cabbage (Brassica oleracea L. var acephala) in the field and laboratory. The field experiments consisted of the evaluation of the proportion of dead aphids on cabbage plants after application of agave extracts. In the field, agave mixed with cow milk caused mortality above 80% and was the most effective extract. Agave mixed with water and agave mixed with ethanol elicited mortality above 60%. In the laboratory, we evaluated the mortality of aphids after the application of different concentrations of aqueous agave extracts; the commercial insecticide deltamethrin was included as positive control. Evaluation took place at 3, 6, 12, 24, 48 and 72 hr after applying the treatment. As expected, deltamethrin was the most effective treatment. However, agave extract at concentrations of 0.750 and 0.500 g/mL caused >70% mortality 3 hr after application. We conclude that A. americana extracts decreased aphid populations and is a promising alternative to the commercial insecticide against aphids in cabbage.
Study of Household Transition from the Disaster Housing Assistance Program (DHAP-Katrina): Final Report

This report presents the results of the Study of Household Transition from the Disaster Housing Assistance Program (DHAP-Katrina). This new approach to post-disaster housing assistance provided a time-limited, declining rental subsidy along with case management services to households affected by Hurricanes Rita and Katrina who still did not have permanent housing two years after the storms. The study’s results indicate that participants were largely satisfied with their DHAP-Katrina housing and with the case management services they received. Results on post-program outcomes some seven years after the storms (and two years after the program ended) indicate that many DHAP-Katrina participants transitioned to the Housing Choice Voucher (HCV) program, but that many other former DHAP-Katrina participants seem to be at risk of housing instability. The executive summary provides background on DHAP-Katrina, a summary of the study’s methodology and key findings, and a brief review of the implications of the results.
Gate-Based Rules for Extracting Attribute Values

Automated ontology population is intended to enrich ontologies. The main entities of an ontological model are classes, subclasses, attributes (datatype properties), relationships (object properties), and instances. Class instances are important to the scientiﬁc community, since some work is devoted to automatically populating ontologies by using statistical methods, information extraction, and natural language processing, among others. The problem is focused on identifying and extracting attribute values of instances. Commonly, such values have a predeﬁned type like numeric, string, boolean, etc. The difﬁculty arises when you want to know which instance belongs to such values. In this paper we propose an approach based on Natural Language Processing (NLP) and Information Extraction (IE) technologies for extracting attribute values. We use syntactic patterns implemented on the GATE (General Architecture for Text Engineering) tool. The results are independent of the application domain and they exhibit promising values of recall, precision, and F-measure.
Building Better Phenotypes: Parsing Individual Differences in Negative Affectivity and Emotion Regulation in the Internalizing Disorders

Human brain anatomical and resting-state functional connectivity have been comprehensively portrayed using MRI, which are termed anatomical and functional connectomes. In this talk, we will provide an overview of the different analysis methods, and applications of resting state. We will also examine effect of tasks on whole brain functional connectivity, which we term as task connectome. Also, most of resting state (and task activation) studies in fMRI have primarily focused on the gray-matter BOLD signals. The signals from the white-matter have usually been considered to be noise dominated and rarely reported in the literature. To address this hypothesis, we evaluated the WM-FNs by performing a clustering analysis to the voxel-based white-matter functional connectivity matrix

An inkjet‐printed inverted‐F antenna for 2.4‐GHz wrist applications

In this article, an inkjet‐printed inverted‐F antenna suitable for a watch‐type wireless communication device is presented. The antenna and covering the 2.4 WLAN band (2.4–2.484 GHz) has thickness (2 mm3) and size (40 × 25 mm2). The performance of the printed antenna is experimentally studied and compared with a reference antenna made of Rogers copper laminate. The effect of inkjet‐printed layer thickness on the antenna performance is presented. In addition, the impact of the user's hand proximity on the antenna performance is studied experimentally. The results showed that the total antenna efficiency increases by 13% and 27% with an increase of 1.5 μm in printed layer thickness and a user's hand to antenna distance of 12.5 mm, respectively. The shape of the radiation pattern of the antenna is distorted due to the proximity of the user's hand. © 2009 Wiley Periodicals, Inc.

Minds for the Market: Non-Cognitive Skills in Post-Soviet Countries

We analyze the effect of socio-political and economic institutions on the development of non-cognitive skills of individuals. We exploit the breakdown of the Soviet Union as a quasi-natural experiment, and apply a difference-in-difference strategy. We focus on two post-Soviet countries, Armenia and Georgia, and compare personality traits of individuals that were born much before the collapse of the Soviet Union with those that were born shortly before or later, relative to individuals from the other developing countries that had never gone through the same institutional changes. We find significantly lower scores of extraversion, openness and grit, and higher scores of hostility of people that lived considerable amount of time under the communist regime. Our findings suggest that institutions can shape the non-cognitive skills of individuals, and thus highlight a channel, through which institutions impact economic development.

A Design of EBG-PIFA for RFID Applications in UHF Band

One of the longstanding problems in planar inverted F antenna (PIFA) is its efficiency, which reduces as PIFA is placed too close to the ground. In this paper a kind of mushroom-like Electromagnetic band gap (EBG) structure with three conductor layers is designed In the UHF band, which has smaller unit cells and thinner thickness compared to classical ones. This kind of mushroom-like EBG structure is used as the reflector of PIFA with capacitor structure. It is demonstrated that PIFAs with EBG grounds have higher radiation efficiency than those with PEC ground. At the same time, no significant changes in the antenna resonance frequency and the radiation patterns are found. The theoretical prediction is well verified by results of both simulation and experiment.
Bagasse Dryer Role in the Energy Recovery of Water Tube Boilers

The sugar and ethanol industry, which uses sugarcane as raw material, utilizes the by-product, bagasse, as fuel. The bagasse is fed with a moisture content of 50% (w.b). Dryers are not being used in the way it is proposed here. This article proposes the introduction of bagasse dryers connected to the energy recovery system of the boilers operating with the exhaust gases. The combination of the dryer with other thermal energy recovery devices, such as an air heater and economizer, is considered. The performance improvement is evaluated. Costs are also taken into account. Finally, an optimized solution for the boiler energy recovery system is proposed.
Forecast of Broad Money Supply Based on Long Short-term Memory Neural Network (LSTM-NN)

The broad money supply (M2) reflects changes in aggregate demand and future inflationary pressures. Forecasting the broad money supply is of great significance to economic and financial decision-making. The factors affecting the changes in the broad money supply are diverse and unclear. Therefore, this article forecasts the broad money supply based on time series. In this article, we established a broad money supply forecasting model based on LSTM (Long Short-Term Memory). This model has a long-term memory function, which effectively solves the problems of vanishing gradient and exploding gradient in the long sequence training process. In the experiment, we have established the model based on RNN (Recurrent Neural Network) and traditional forecasting models such as exponential smoothing forecasting models and regression forecasting models to compare with the broad money supply forecasting model based on LSTM. The exponential regression forecasting model with the highest prediction accuracy in the traditional model has a goodness of fit greater than 0.99. But experiments show that the prediction accuracy of the broad money supply forecasting model based on LSTM is 2 orders of magnitude higher than the prediction accuracy of the exponential regression forecasting model. This shows that the broad money supply forecasting model based on LSTM has extremely high prediction accuracy. The forecasting model of broad money supply based on LSTM is of great significance in the short-term forecasting of Chinese broad money supply.
Causes of Musculo-Skeletal Disorder in Textile Industry

Poor work pattern and working environment gives unnecessary physical efforts, which reduce efficiency and productivity also. Sustaining any static posture, such as sitting, increases the demand on the muscles, ligaments, and other soft tissues of the musculoskeletal system. It is not surprising then that overall discomfort and pain in the back, neck, and shoulders are common symptoms reported by workers who sit for most of their workday. Sitting alters the normal curvature of the spine and puts pressure on the discs. With prolonged sitting this pressure can cause compression of the discs. These resulting chronic back pain and possible nerve damage can impact on workers ability degeneration of the cervical spine, sometimes known as cervical spondylitis, can have serious consequences. Compression of the spinal cord at the level of cervical spine can take place, resulting in weakness and wasting of the upper limbs. This may then spread to the lower limbs. high percentages were suffered from MSDs commonly associated with poor ergonomic design in the workplace. MSDs commonly associated with poor ergonomic design in the workplace. Without the application of ergonomic principles, tools, machines, equipment, and workstations are often designed without much consideration of the fact that people are of all different heights, shapes, and sizes and have different levels of strength. It is important to consider these differences in order to protect worker's health and comfort. Without the application of ergonomic principles, workers are often forced to adapt themselves to poor working conditions.
Increasing talk-time with efficient linear PA's

In order to meet the TETRA linearity specification the power amplifier (PA) linearisation methods in common usage today usually have low efficiencies (e.g. Cartesian loop and adaptive predistortion). The market drivers for lightweight terminals and long talk-time are directly related to transmitter efficiency. Techniques that make the radio more power efficient allow smaller (lower capacity) batteries or a longer useable time between battery charge-cycles. The transmitter places a heavy demand on the battery and therefore utilising more efficient transmitters can increase talk-time or reduce the battery size. Firstly it is shown that to obtain a high transmitter efficiency (>50%) the PA needs to be biased as class-C. The effect power amplifier efficiency has on talk-time is demonstrated for a handportable with fixed power overhead owing to the digital processing required to transmit a burst. It is shown that the PA efficiency for a transmitter operating backed off (under power control), has a marginal impact on the talk-time and that the PA efficiency effects on talk-time are largest at higher output powers. This is put in context by a review of the various linearisation schemes such as Cartesian loop, polar loop, 2nd harmonic injection, envelope elimination and restoration (EER), predistortion methods, and synthesis techniques (e.g. LINC and CALLUM). The review also discusses which methods are not suitable for handportable design, and documents the strengths and weaknesses of the remaining methods. The paper shows that to increase the power efficiency and (thus talk-time) hybrid solutions to power amplifier linearisation are required. Finally, existing hybrid solutions and their shortfalls are discussed. (22 pages)
Effect of S–Se Bioisosteric Exchange on Affinity and Intrinsic Efficacy of Novel N-acylhydrazone Derivatives at the Adenosine A2A Receptor

In this work, we evaluated the conformational effect promoted by the isosteric exchange of sulfur by selenium in the heteroaromatic ring of new N-acylhydrazone (NAH) derivatives (3–8, 13, 14), analogues of the cardioactive compounds LASSBio-294 (1) and LASSBio-785 (2). NMR spectra analysis demonstrated a chemical shift variation of the iminic Csp2 of NAH S/Se-isosters, suggesting a stronger intramolecular chalcogen interaction for Se-derivatives. To investigate the pharmacological profile of these compounds at the adenosine A2A receptor (A2AR), we performed a previously validated functional binding assay. As expected for bioisosteres, the isosteric-S/Se replacement affected neither the affinity nor the intrinsic efficacy of our NAH derivatives (1–8). However, the N-methylated compounds (2, 6–8) presented a weak partial agonist profile at A2AR, contrary to the non-methylated counterparts (1, 3–5), which appeared as weak inverse agonists. Additionally, retroisosterism between aromatic rings of NAH on S/Se-isosters mimicked the effect of the N-methylation on intrinsic efficacy at A2AR, while meta-substitution in the phenyl ring of the acyl moiety did not. This study showed that the conformational effect of NAH-N-methylation and aromatic rings retroisosterism changed the intrinsic efficacy on A2AR, indicating the S/Se-chalcogen effect to drive the conformational behavior of this series of NAH.
Clinical Features of Disseminated Intravascular Coagulation According to the French-American-British Classification in Patients With Acute Leukemia and Thrombomodulin Alfa Treatment—A Cohort Study Using a Postmarketing Surveillance Database

The aims of this study were to analyze the clinical features of a large number of cases with disseminated intravascular coagulation (DIC) associated with acute leukemia and to assess the safety and efficacy of thrombomodulin alfa (TM-α) using the French-American-British (FAB) classification of hematological malignancies. We retrospectively examined 644 patients with acute leukemia in postmarketing surveillance for TM-α. M3, M2, M4, M1, and M5 subtypes of acute myeloid leukemia (AML) and L2 and L1 subtypes of acute lymphoblastic leukemia (ALL) have been found more frequently among patients with DIC. Bleeding symptoms at baseline were more frequent in M3 and M7 subtypes. Fibrinogen concentrations were lower, and plasmin-plasmin inhibitor complex values were higher in M3 and Philadelphia-positive (Ph+) ALL. Overall DIC resolution rate was 60.2%, higher in L1 and Ph+ ALL, lower in M1, and generally higher in ALL than in AML. Overall survival rate was generally high, at 79.8%, with higher rates in L3, Ph+ ALL, and M3. Regardless of FAB subgroup, TM-α showed improved bleeding symptoms and DIC scores in clinical practice for DIC patients with acute leukemia.
MoSAIC: Mobile System Availability Integrity and Confidentiality

We describe the work we are conducting on new middleware services for dependable and secure mobile systems. This work is based on approaches a la peer-to-peer in order to circumvent the problems introduced by the lack of infras- tructure in self-organizing networks of mobile nodes, such as MANETs. The mechanisms we propose are based on collaboration between peer mobile devices to provide mid- dleware services such as trust management and critical data storage. This short paper gives a brief description of the problems we are trying to solve and some hints and ideas towards a solution.
