Published: December 2020

We present an analysis of the new, deep (94 ksec) Chandra ACIS-S observation of radio-loud active galaxy CGCG 292−057, characterized by a LINER-type nucleus and a complex radio structure that indicates intermittent jet activity. On the scale of the host galaxy bulge, we detected excess X-ray emission with a spectrum best fit by a thermal plasma model with a temperature of ∼0.8 keV. We argue that this excess emission results from compression and heating of the hot diffuse fraction of the interstellar medium displaced by the expanding inner, ∼20 kpc-scale lobes observed in this restarted radio galaxy. The nuclear X-ray spectrum of the target clearly displays an ionized iron line at ∼6.7 keV, and is best fitted with a phenomenological model consisting of a power-law (photon index  ≃ 1.8) continuum absorbed by a relatively large amount of cold matter (hydrogen column density  ≃0.7 × 1023 cm−2), and partly scattered (fraction ∼3%) by ionized gas, giving rise to a soft excess component and Kα line from iron ions. We demonstrate that the observed X-ray spectrum, particularly the equivalent width of Fe XXV Kα (of order 0.3 keV) can in principle, be explained in a scenario involving a Compton-thin gas located at the scale of the broad-lined region in this source and photoionized by nuclear illumination. We compare the general spectral properties of the CGCG 292−057 nucleus, with those of other nearby LINERs studied in X-rays.
Background Microwave Emission and Microflares in Young Active Region 12635

Published: December 2020

The goal of this work is to study the atmospheric heating above isolated AR 12635 during a period in which a quasistationary increase in microwave and soft X-ray emission is combined with a series of B- and C-class microflares. Analysis of photospheric vector magnetograms showed that an increase in the SXR brightness lasting 14 hours was observed during the simplification of the magnetic structure and the growth of vertical currents in the head part of the active region. A long-term increase of SXR and microwave emission occurred when the total unsigned vertical current exceeded the critical value and coincided in time with the increased level of the emission measure calculated from the GOES X-ray data. Against the background of quasistationary emission, microflares lasting 6–10 minutes occurred. In the hard X-ray range, bursts are recorded with RHESSI channels up to 25 keV. In microwave emission, pulsed and smooth components are distinguished during microflares. The first component was recorded in the 4.5–7.5 GHz range at the beginning of microflares and it is generated by a small population of relativistic electrons by the gyrosychrotron mechanism. The smooth component of the bursts dominated at 17 GHz and was emitted by bremsstrahlung. It is shown that the sources of quasistationary emission and microflares coincide with each other and with the bremsstrahlung source calculated from the differential emission measure obtained from the EUV maps. Coronal magnetic field reconstruction shows that the release of energy on both timescales occurs in a stably existing bundle of magnetic field lines.
Defining and Evaluation of Competencies of an Officer of the Czech Armed Forces
Authors: Kuba Jaroslav , Saibert Richard
Published: December 2020

The article deals with the issue of identification and evaluation of the competencies of senior officers of the Czech Armed Forces. Paper investigates the role of the authorities responsible for military branches and military occupation specialties in the system of defining officer´s competencies. It was also examined the scope of possible application of the competency model of a professional soldier defined by the National System of Occupations in the process of career management. As a comprehensive and optimal solution, a full application of competency model is proposed. The partial application of the competency model is based only on the use of the soft competencies component. Both of these proposals are formulated primarily for the purpose of describing the job position and official evaluation. The paper also brings a number of proposals in the conceptual and normative area circumscribing and strengthening the role of the responsible authorities in the process of defining the officer´s competencies.

Published: December 2020

A pesquisa cujos resultados apresentamos neste artigo teve por objetivo investigar se a utilização de um determinado objeto de aprendizagem por meio da lousa digital seria capaz de propiciar a interatividade e a interação entre os recursos tecnológicos, os estudantes e o professor. O artigo traz a descrição de um produto educacional e os procedimentos estabelecidos para sua exploração junto a um grupo de dez alunos de uma turma do 6º ano do Ensino Fundamental de um colégio da rede paranaense estadual de ensino que possuía esse equipamento tecnológico específico – a lousa digital – desde o ano de 2013. As atividades que compõem o objeto de aprendizagem – Feira dos Pesos – foram exploradas pelos alunos por intermédio de uma lousa digital. Nossa opção foi por uma abordagem qualitativa de investigação, pois a coleta de dados ocorreu durante aulas de Matemática no Ensino Fundamental, por meio de notas de campo e de gravações em vídeo realizadas pelos pesquisadores. Para a interpretação das informações coletadas pautamo-nos nos procedimentos da Análise de Conteúdo utilizando os procedimentos de organização, interpretação e análise, segundo os conceitos metodológicos e analíticos dos autores Moraes (1999) e Moraes e Galiazzi (2011). Tal processo analítico permitiu evidenciar indícios de interatividade (com a lousa digital, o objeto de aprendizagem, o ultrabook, o celular e o quadro negro) e de interação (com outros alunos, professores e integrante da equipe pedagógica) que surgiram naturalmente em decorrência da realização das tarefas da atividade explorada na lousa digital e no ultrabook.

Diversity patterns of free-living nematode assemblages in seagrass beds from the Cuban archipelago (Caribbean Sea)
Authors: Armenteros Maickel , Rodríguez-García Patricia , Pérez-García José Andrés , Gracia Adolfo
Published: December 2020

Diversity patterns of free-living marine nematodes in tropical seagrass beds are understudied. Here, we describe the species richness and assemblage composition of nematodes in 13 seagrass sites covering the whole Cuban archipelago. Nematodes were collected fromThalassia testudinumseagrass beds and identified to species level. We provide a checklist of nematode species from seagrass beds. The species richness of nematode assemblages is high, with 215 species, 138 genus, 35 families, seven orders and two classes. That γ-diversity is higher than other studies and points to seagrass beds as diversity hotspots of free-living marine nematodes. Local species richness in seagrass bed sites is about 57 ± 17 species and broadly similar across the sites, despite the environmental heterogeneity. The geographical distance plays a weak, but significant, role on the decay of similarity likely affected by limited dispersal of nematodes. The pairwise similarity values, related to poor-coloniser nematodes, were twice more affected by the distance than those related to good-colonisers, possibly due to differential success of transport and settlement.
Merger of Betula tatewakiana (Betulaceae) from northern Japan with northeast Asian B. ovalifolia based on ploidy level

Published: December 2020

It has been controversial whether Betula tatewakiana, a dwarf birch distributed in Hokkaido of northern Japan, is an endemic species or a synonym of B. ovalifolia broadly distributed in northeast Asia. The endemic hypothesis is based on the idea that B. tatewakiana is diploid while B. ovalifolia is tetraploid and that they are separated based on the ploidy level; however, no chromosome data have actually been published before. Resolving the taxonomic problem is crucial also in judging the conservation priority of B. tatewakiana in a global perspective. Our chromosome observation revealed that B. tatewakiana is tetraploid as well as B. ovalifolia. We also conducted morphological observations and clarified that B. tatewakiana is morphologically identical to B. ovalifolia in white hairs and dense resinous glands respectively on adaxial and abaxial leaf surfaces, in which they differ from closely related species in the same section Fruticosae. We conclude that the hypothesis that B. tatewakiana is a Hokkaido endemic based on the ploidy level is not supported and that B. tatewakiana should be merged with B. ovalifolia.

Transition énergétique et durabilité des trajectoires de développement : vers un simple ajustement à la marge ou une transformation de rupture ?
Authors: Quenault Béatrice
Published: December 2020

Cet article analyse le processus d’imprégnation progressif dans l’agenda international des enjeux de la transition énergétique réinterprétés à la lumière de la problématique du développement durable et des tensions entre les approches de la durabilité forte et faible. Soulignant les ambivalences des modalités d’appropriation et de traduction en politiques publiques de ces deux concepts, l’article montre que l’infléchissement du développement durable assimilé à la croissance verte entérine le triomphe de la vision néolibérale de la durabilité faible privilégiant une transition énergétique techno-économique faible elle aussi ; cette dernière, liée à un simple ajustement à la marge des trajectoires de développement, s’opère au détriment d’une transition éco-centrée marquant une transformation plus radicale vers la sobriété énergétique et une durabilité forte.

Comment mesurer la contribution de l’énergie à la croissance économique ?
Authors: Pellegris Alban
Published: December 2020

La théorie néoclassique considère que l’énergie joue un rôle mineur dans le processus de croissance et pourrait donc aisément être substituée. Ce traitement de l’énergie a été vivement critiqué par le courant de l’économie écologique. Certains de ses auteurs ont tenté d’intégrer les apports de la thermodynamique aux fonctions de production agrégée mais leur démarche n’est pas totalement satisfaisante : elle continue de confondre production physique et valeur économique. Ainsi, nous suggérons de mesurer la contribution de l’énergie au processus de croissance à partir de son rôle dans la formation des coûts. Classification JEL : A12, Q40, O13
Energy management method for an unpowered landing
Authors: Li Xiaoxiao , Shi Yingjing , Li Rui , Cao Shida
Published: December 2020

The unpowered landing of unmanned aerial vehicle (UAV) is a critical stage, which affects the safety of flight. To solve the problem of the unpowered landing of UAV, an energy management scheme is proposed. After the cruise is over, the aircraft shuts down the engine and begins to land. When the aircraft is in the high altitude, the dynamic pressure is too large, and it is difficult to open the speed brake. When the aircraft is in the low altitude, it is close to the runway. The method of S-turn may make the aircraft veer off the runway and may be unable to land. So two different schemes of high altitude and low altitude are designed to control energy. In the high altitude, when the energy is too high, it takes the S-turn scheme to consume excess energy. At the same time, the availability and reasonability of the S-turn scheme is demonstrated. In the low altitude, the open angle of speed brake is controlled to adjust the energy consumption. Finally, the simulation results are given to illustrate the availability of energy management.

In this article, we introduce the concepts of graded $ s $-prime submodules which is a generalization of graded prime submodules. We study the behavior of this notion with respect to graded homomorphisms, localization of graded modules, direct product, and idealization. We succeeded to prove the existence of graded $ s $-prime submodules in the case of graded-Noetherian modules. Also, we provide some sufficient conditions for the existence of such objects in the general case, as well as, in the particular case of a grading by a finite group, polycyclic-by-finite group, or by $ \mathbb{Z} $, in addition to the interesting case of crossed product grading, which includes the class of group rings.

The Loads on Yacht Anchor Cables
Authors: Klaka K
Published: December 2020

The loads exerted on an all-chain anchor cable of a 10m yacht were measured during full scale trials in sheltered waters and steady wind. The peak recorded load was found to decrease significantly with increasing scope ratio, whereas the mean load was only weakly affected by scope ratio. The trials results were used to calculate the depth of water in which the pull at the anchor just remains horizontal for a range of wind speeds and cable lengths. The resulting relationship between maximum water depth and cable length is approximately quadratic. The required scope ratio for a given water depth increases with increasing windspeed. The required scope ratio for a given windspeed decreases with increasing depth.
Multi-Objective Optimisation and its Application to Concept Development in Floating Offshore Systems
Authors: Gallagher P
Published: December 2020

This paper addresses the need for a rapid, multi-disciplined and rational approach to floating system concept development and selection during the very earliest stages of project definition. It describes the implementation of a modified multi- objective Genetic Algorithm for this purpose. A formulation of the NSGA-II algorithm is combined with additional Target Functions to reduce otherwise large multi-disciplined problems to more tractable solution using tools commonly available in the design office. It also provides a rational basis for the comparison of different design solutions each of which are Pareto Optimal with respect to the technical and economic performance of each underlying concept. A specific example of marginal field development using a novel FPSO concept is presented. Starting with just the oil field location and reserves estimate, the algorithm provides the means to define preliminary hull form and production facility capacities, match performance to payload, and give preliminary indicators of likely investment performance. The method may also be applied more generally in preliminary ship design, particularly where it is possible to model economic performance alongside efficiency, safety and key technical factors in hydrodynamics and structures.
Liminal governance in the Lisbon night
Authors: Nofre Jordi , Martins João C. , Vaz Domingos , Pires Cristina Vale
Published: December 2020

The expansion and commodification of nightlife in the central areas of Lisbon over recent years have involved some critical and unwanted social, spatial, and urban governance impacts, as well as the worsening of community livability during nighttime hours. Taking the former harbor neighborhood of Cais do Sodré in Lisbon as a case study, this paper examines the range of nightlife-related regulations, standards and laws approved over the past few years and implemented at local and national level regarding nighttime leisure. The paper will argue that public-led interplay between the privatization and liminality of public safety in nightlife districts and the (neo)liberalization of the opening hours regulation are at the basis of the liminal governance of nightlife in Lisbon.
Building a model to analyse and compare social policies on ageing
Authors: Bárrios Maria João , Fernandes Ana Alexandre , Fonseca António Manuel
Published: December 2020

Demographic ageing results in issues both for individuals and for organizations, with regards to social, economic and health issues. The challenge for public policies is to create the adequate resources and to adapt devices, in order to facilitate and allow an ageing process with well-being.The WHO’s proposal of Active Ageing has a great potential in guiding ageing policies, in particular local interventions. In this research we aimed to convert the active ageing concept into a practical instrument, built for use by policy-makers, researchers and stakeholders to evaluate and compare different social policies on ageing. We have proceeded to the validation of both the content and the design of the instrument, using the Delphi technique.Through the instrument created, it will be possible to analyse ageing policies from the active ageing point of view, to compare programmes and communities/organizations, to share the best policy practices and identify the least appropriate policy actions as the intervention priorities, adjusting and improving them.

A Mathematical Model for Integrated Green Healthcare Supply Network Design
Authors: Nasrollahi Meisam , Safaei Mehdi , Mahmoodi Nooshin
Published: December 2020

This research presents a novel integrated mathematical programming model for green healthcare supply network design. A multi-graph integrated supply network was designed to meet real-world situations. Minimizing total cost and minimizing delivery time are considered as the objective functions. Since the considered problem is np-hard and the presented mathematical model is very complex and highly constrained, an innovative non-dominated ranked genetic algorithm (NRGA) called M-NRGA is developed to solve the real word problems. Three different selection procedures were implemented to improve the quality and diversity of solutions in the Pareto-front resulted from M-NRGA. Several numerical examples and a case study are solved to validate the model and performance evaluation of the solution algorithm. Four different performance metrics are implemented for performance evaluation of the solution algorithm. The quality of resulted solutions, the diversity of the solutions in the Pareto front are calculated for evaluation. The results are compared with two other meta-heuristic algorithms.

Published: December 2020

The purpose of this paper is to gain insights from the online product reviews of e-commerce sites such as Flipkart and Amazon and analyze its impact on third party sellers. To judge the authenticity of a product, reviews are more useful than ratings, since ratings do not give a complete picture. It is always preferred to consider both the product and seller reviews to have a seamless delivery and defect less product. In this paper, natural processing methods are used to gain insights by considering online reviews of a product. Methods such as sentiment analysis, bag of words model help to understand the impact of online product reviews on the seller's ratings and their performance over some time. The reviews are categorized into positive, negative, and neutral using sentiment analysis. Further, topic modeling is done to find out the topic reviews are majorly referring to. The seller reviews for a specific product after analysis are compared with the overall seller reviews to judge the authenticity. The results of this paper would be beneficial to both the consumers and sellers.
Deploying a “Good Jobs” Strategy in Service Sectors for Enhancing Competitive Advantage
Authors: Madhani Pankaj M.
Published: December 2020

Many service companies believe that there is a trade-off between investing in employees and offering the lowest prices. They offer few benefits, no career paths, and, hence, are considered as bad jobs. Conventional wisdom holds that bad jobs are the unavoidable price of low-cost service. However, this research emphasizes that investing in people and processes actually can boost customer experience and decrease costs. The good jobs strategy is a model for investing and empowering front-line employees in service industries and revamping operations to support those employees. The good jobs strategy is an approach to improving productivity and customer satisfaction in service industries. This research works in this direction and develops various frameworks for smooth deployment of the good jobs strategy. The research also formulates financial measurement and evaluation models for calculating benefits of the good jobs strategy and provides diverse illustrations of its successful deployment.

Urban Digital Infrastructure, Smart Cityism, and Communication
Authors: McQuire Scott
Published: December 2020

This article takes stock of the smart city concept by locating it in relation to both a longer history of urban computing, as well as more recent projects exploring the vexed issues of participatory urbanism, data ethics and urban surveillance. The author argues for the need to decouple thinking regarding the potential of urban digital infrastructure from the narrow and often technocentric discourse of ‘smart cityism'. Such a decoupling will require continued experimentation with both practical models and conceptual frameworks, but will offer the best opportunity for the ongoing digitization of cities to deliver on claims of ‘empowering' urban inhabitants.

It is the technology behind all the crypto currencies like Bitcoin, Litecoin, Ethereum, and now finding its way to record everything possible. This paper focuses on the basic framework of blockchain model, its pre-requisites, and challenges of blockchain. Various current real-time applications of the technology are also discussed. Finally, an application area has been proposed that can be used to create a huge database of the citizens of the country and facilitate them with ease of access to their personal data. It will open new ways of data analysis at a nationwide scale.
Risk Reduction Privacy Preserving Approach for Accessing Electronic Health Records
Authors: Saxena V. K. , Pushkar Shashank
Published: December 2020

In the healthcare field, preserving privacy of the patient's electronic health records has been an elementary issue. Numerous techniques have been emerged to maintain privacy of the susceptible information. Acting as a first line of defence against illegal access, traditional access control schemes fall short of defending against misbehaviour of the already genuine and authoritative users: a risk that can harbour overwhelming consequences upon probable data release or leak. This paper introduces a novel risk reduction strategy for the healthcare domain so that the risk related with an access request is evaluated against the privacy preferences of the patient who is undergoing for the medical procedure. The proposed strategy decides the set of data objects that can be safely uncovered to the healthcare service provider such that unreasonably repeated tests and measures can be avoided and the privacy preferences of the patient are preserved.
Dermatoscopy Using Multi-Layer Perceptron, Convolution Neural Network, and Capsule Network to Differentiate Malignant Melanoma From Benign Nevus
Authors: Tiwari Shamik
Published: December 2020

Epiluminescence microscopy, more simply, dermatoscopy, entails a process using imaging to examine skin lesions. Various sorts of skin ailments, for example, melanoma, may be differentiated via these skin images. With the adverse possibilities of malignant melanoma causing death, an early diagnosis of melanoma can impact on the survival, length, and quality of life of the affected victim. Image recognition-based detection of different tissue classes is significant to implementing computer-aided diagnosis via histological images. Conventional image recognition require handcrafted feature extraction before the application of machine learning. Today, deep learning is offering significant choices with the progression of artificial learning to defeat the complications of the handcrafted feature extraction methods. A deep learning-based approach for the recognition of melanoma via the Capsule network is proposed here. The novel approach is compared with a multi-layer perceptron and convolution network with the Capsule network model yielding the classification accuracy at 98.9%.

Sexual Harassment Training Focused Solely on Protecting Organizations From Lawsuits Won't Change a Toxic Culture for Women to an Inclusive One
Authors: Burrell Darrell Norman , Lu Shanel , Lindsay Preston Vernard Leicester , Burton Sharon L. , French Roderick , Finch Aikyna , McLester Quatavia , Springs Delores
Published: December 2020

The location where workplace sexual harassment occurs points to the importance of workplace structures and practices for the precipitation of sexual harassment. In fact, some of the current theoretical explanations of sexual harassment focus primarily on organizational features that may facilitate sexual harassment, such as hierarchies and organizational cultures. Organizational literature suggests that in recent decades there has been a trend toward increased use of organizational practices that might empower workers, make organizations more inclusive, and constructively change organizational cultures through interventions. Assumptions about men and women contained in hegemonic gender beliefs can become embedded in organizational structures, authority lines, job classifications, institutional rules, and employee interactions. This paper explores these notions through a case study of an organizational intervention and a content analysis of the literature.
Who Wants to Go to Work Revisited
Authors: Chan Alan
Published: December 2020

This paper extends and re-examines the author's previous findings using the same 2010 Canada Survey of Household Spending. Using a more advanced econometrics method, this paper empirically re-tests the four potential factors (price, economic, demographic, and geographic) that were significant. This paper concludes that economic and demographic factors are major determinants for hours of work by Canadians. Unlike the previous study, no provincial effects can be found. This means Atlantic Canadians work less not because of lifestyle choices but because of the lack of economic opportunities.
The Importance of FDI Inflows in Turkey
Authors: Gökmen Aytaç
Published: December 2020

The Republic of Turkey is located at the threshold of Eurasia consolidating the East with the West and North with the South. Moreover, it is at the conjunction of many investment and commercial routes. These advantages disposition gives Turkey a favorable investment climate especially in the form of FDI. The volume of FDI in the world is well over 1 trillion USDs, but Turkey can attract only a small amount of it. Even tough Turkey has substantial foreign debt and commercial deficits, it still has a strong government with political stability. Thus, the aim of this paper is to present the literature on FDI, FDI and economic growth nexus, a historical background of FDI in Turkey, and FDI's contributions to the Turkish economy.

Single-Vehicle Run Off Road (ROR) crash has been the leading crash type in terms of frequency and severity in Thailand. In this study, multinomial logit analysis was applied to identify the risk factors potentially influencing driver injury severity of single-vehicle ROR crash using accident records between 2011 and 2017 which were extracted from Highway Accident Information Management System (HAIMS) database. The analysis results show that the age of driver older than 55 years old, male driver, driver under influence of alcohol, drowsiness, ROR to left/right on straight roadway increase the probability of fatal crash, while other factors are found to mitigate severity such as the age of driver between 26-35 years old, using seatbelt, ROR and hit fixed object on straight and curve segment of roadway, mounted traffic island, intersection-related and accident in April. This study recommends the need to improve road safety campaign, law enforcement, and roadside safety features that potentially reduce level of severity of driver involving in single-vehicle ROR crash.
The Gross National Happiness Framework and the Health System Response to the COVID-19 Pandemic in Bhutan
Authors: Dorji Thinley
Published: December 2020

Bhutan is a lower-middle–income country with limited tertiary-care health infrastructure and shortage of human resources. The country’s response to the COVID-19 pandemic is guided by the principle of Gross National Happiness (GNH), which prioritizes the well-being and happiness of people over conventional socioeconomic indicators. The king’s leadership and government’s decisions based on public health science helped in the control of the pandemic and reduce economic losses. The government implemented some unique and unconventional public health measures such as facility quarantine for those with high-risk exposure, an increase in quarantine period to 21 days, free testing and treatment, and population-based screening tests. Early and extensive contact tracing, extensive testing, effective communications, zoned travel restrictions, and adoption of physical distancing and hygiene measures limited COVID-19 transmissions within the country. Community participation from voluntary groups and civil society organizations helped deliver non-health services while hospitals provided uninterrupted routine health services through its primary healthcare network. All COVID-19 cases were treated in hospitals, and the country has had zero reported COVID-19 deaths. This article describes how the concept of GNH provided the framework for the government to respond to this pandemic.

LOAN MORATORIUM 2020- ITS IMPACT ON INDIAN BANKS
Authors: Mehta Meera , Kaul Rishab
Published: December 2020

A moratorium is a temporary suspension of an activity or law until further consideration calls for a lift on the suspension, as in the case of the issues that led to the moratorium are resolved. Moratoriums may be imposed by regulators, by a business, or by the government. A moratorium is often ordered in response to situations of crisis. Moratoriums are not new to the Indian banking sector and have been granted and imposed in multiple instances in the last 20 years. Since 1999 moratoriums have been imposed on 9 banks for various reasons. Very recently, the Reserve Bank of India (RBI) offered a six-month moratorium between March 1, 2020, and August 31, 2020, on all loan equated monthly instalments (EMIs) to help lessen the troubles faced by borrowers due to the COVID-19 pandemic. This paper aims to study the recently granted moratorium by the RBI to assess and predict its impact on the banking sector. The study will also reflect on similar instances of moratoriums that have been granted in the United States, Greece, and Thailand in the last 20 years.

Segundo a Organização mundial da saúde (OMS), a depressão é um transtorno comum que tem crescido exponencialmente em todo o mundo, com uma estimativa de mais de 300 milhões de pessoas acometidas por esta condição, o que a torna um problema de saúde pública. Dentre as consequências, destacase o comprometimento das atividades cotidianas e sociais dos indivíduos em todas as faixas etárias, podendo ocasionar desfechos trágicos e risco de vida. O presente estudo tem como objetivo estudar as alterações morfológicas em cérebros de pessoas diagnosticadas com depressão. Para tanto, foi realizada uma revisão integrativa da literatura nas bases de dados Scielo e Medline. Após leitura criteriosa, foram selecionados cinco artigos que responderam aos critérios de inclusão. A análise dos artigos mostrou que cérebros de pessoas diagnosticadas com depressão apresentam alterações visíveis em exames de neuroimagens, como a ressonância magnética. As alterações identificadas foram volumes subcorticais menores, volumes ventriculares maiores, menor volume da substância cinzenta do córtex orbitofrontal, anormalidade no córtex pré-frontal, perda de diferenciação entre substância branca e cinzenta e envolvimento das estruturas límbicas. O estudo evidenciou, portanto, que os exames de neuroimagem podem apresentar-se como um recurso importante para a obtenção de um diagnóstico mais rápido e preciso dessa patologia.

A garantia da qualidade é o mecanismo que propicia ao laboratório de análises clínicas apresentar resultados confiáveis adequados e corretamente interpretados. Na rotina de trabalho desses laboratórios, utilizam-se calibradores, que são padrões conhecidos com características quantitativas e/ou qualitativas determinadas, os controles podem ser utilizados para medir alguns parâmetros de qualidade laboratorial. A depender dos fabricantes, existem algumas sugestões de manuseio a ser seguido, para então, obter maior fidedignidade de aferição. O desempenho do calibrador pode ser afetado por erros de reconstituição, de homogeneização, armazenamento incorreto, contaminação da água ou vidraria. Dessa forma, este trabalho avaliou a estabilidade de controles comerciais submetidos a temperaturas diversas encontradas em situações reais de laboratório, como a refrigeração entre 4-8 ºC, exposição sob bancada de trabalho, a temperatura ambiente, e armazenada dentro de um automóvel, em temperaturas de 60-80 ºC, por períodos de 1 a 12 dias. Tanto o tempo quanto a temperatura em que as alíquotas são armazenadas não ocasionaram alterações nesse produto (exceto para a creatinina, apresentou-se instável no 12º dia do estudo), apresentando valores dentro das faixas estimadas, e possivelmente as alíquotas fora das faixas estimadas devem-se a erro sistemático.
