Un escritor de vanguardia en la Guinea española. Relativismo cultural y otros ismos en Cartas de la Guinea de Agustín Miranda Junco
Authors: Gil Hernández Roberto
Published: June 2022

Acabada la Guerra Civil española, Agustín Miranda Junco publica una obra desconocida pero indispensable para comprender la deriva intelectual del país a principios del siglo XX. Se trata de Cartas de la Guinea, un texto literario cuyas pretensiones etnográficas permiten constatar el papel que juegan, en las representaciones occidentales del África negra, paradigmas novedosos como el vanguardismo y el relativismo cultural. En este artículo se acreditan, desde el punto de vista del pensamiento descolonial, los vínculos que existen entre tales planteamientos y el patrón de poder mundial que justifica la presencia de Europa en dicho territorio: la colonialidad. A modo de conclusión, se pretende demostrar que la modernidad radical que abrigan este tipo de propuestas académicas y estéticas, no es suficiente para que sus respectivas proyecciones de la otredad europea se desprendan del racismo, el sexismo, el clasismo y el eurocentrismo que hacen posible la supremacía imperial de Occidente en el continente africano.

O COMEÇO DA LIBERDADE EM SCHELLING
Authors: Scoralick Klinger
Published: June 2022

Schelling (1775-1854) é um dos maiores expoentes o romantismo alemão e, por certo, ainda que não ignore a noite, é um pensador do dia, que ama a clareza e foge das fumosidades da Schwärmerei, isto é, recusa toda espécie de sentimentalismo, paixão, exaltação, fanatismo e entusiasmo enganador, que se cumpre através da renúncia da razão. Apesar propor uma “metafísica do irracional”, Schelling evita a falta de mediação racional e tomando o realismo como o corpo e o idealismo como a alma da filosofia, buscando um princípio que se realiza e adquire sangue. Para tanto, Schelling introduz em um sistema pouco acabado e satisfeito a possibilidade de se pensar seu fundamento como vida e liberdade. Não se atendo à distinção dos conceitos mais gerais e buscando avaliar corretamente a totalidade, Schelling busca com agudeza evitar o terrível erro que faz com que tanto o gramático quanto o ignorante possam julgar e sentenciar sobre aquilo que foi mais pensado. Neste texto que aqui se apresenta propomos uma exposição sobre o problema do fundamento da liberdade, a partir das Investigações filosóficas sobre a essência da liberdade humana­, indicando a crítica ao princípio de identidade e a dimensão trágica que o engendra.
UMA EXPOSIÇÃO E DEFESA DA COERÊNCIA DO RELATO DO PRIMEIRO PECADO EM TOMÁS DE AQUINO
Authors: Reis Gabriel
Published: June 2022

Meu objetivo geral é explicar como o mal moral poderia entrar em um universo inteiramente bom criado por Deus. Dada a crença cristã tradicional de que Deus criou os anjos inteiramente bons e alguns deles caíram em pecado pelo uso da liberdade, busco apresentar de maneira coerente o relato de Tomás de Aquino na Suma Teológica sobre o primeiro pecado. Para tal, recorro a noção de akrasia presente em Sócrates e Aristóteles com a finalidade de esclarecer a explicação de Tomás sobre o assunto em questão. Em seguida, apresento a interpretação de Tomás sobre a akrasia e as dificuldades que surgem para um relato coerente do primeiro pecado. E, por fim, a partir de uma reunião de alguns textos da Suma Teológica e On Evil de Tomás, ofereço uma explicação coerente da escolha de Lúcifer, que sendo criado inteiramente bom, rebelou-se contra Deus.
VULNERABILIDADE
Authors: Araújo Luana Adriano
Published: June 2022

Embora amplamente utilizado nos discursos jurídicos atuais, o termo “vulnerabilidade” carece de uma precisão analítica e de parâmetros que demarquem o binário vulnerável/não-vulnerável, especialmente em se considerando que (i) a mesma palavra pode ter trajetórias teóricas e efeitos práticos diferentes; e (ii) no direito, a qualificação como vulnerável pode ter efeitos normativos específicos. Nesse trabalho, busco caracterizar duas perspectivas de vulnerabilidade, tecendo, assim, uma sugestão de fixação de uma taxonomia da vulnerabilidade: uma individual, que a entende como um atributo existencial de um sujeito individualmente considerado (podendo ser, nesse sentido, universal ou inerente); e uma relacional, que apenas emerge em contextos de comparações intersubjetiva entre indivíduos. Em seguida, aponto para uma utilização jurídica da vulnerabilidade como fator de estruturação de políticas sociais em contextos distributivos, que se aproxima da perspectiva individual; e para um uso jurídico do termo que busca fornecer aplainamentos de capacidades em contextos de relações privadas, o qual melhor instrumentaliza o conceito de vulnerabilidade relacional.
DIREITOS HUMANOS E ATUAÇÃO DA POLÍCIA DA REPÚBLICA DE MOÇAMBIQUE NA MANUTENÇÃO E REPOSIÇÃO DA ORDEM PÚBLICA
Authors: Luciano Armando Manuel , Karasinski Murilo
Published: June 2022

Na atualidade, a salvaguarda do direito à liberdade de expressão e as conquistas da democracia estão se tornando cada vez mais comuns no Estado de Direito. Portanto, democracia é vista como sinônimo de reuniões ou manifestações pacíficas ou violentas, acidentais ou previamente notificadas. Face aos novos riscos e ameaças à ordem e tranquilidade públicas, a gestão destes incidentes requer muito empenho por parte das autoridades policiais e do pessoal da segurança pública moçambicanos. Neste capítulo, discute-se o ramo da PRM que mantém e restaura a ordem pública. No caso de desordem pública, há evidências do nível de comando e controle, e do nível de atualização das tropas. A pesquisa ajudará a entender a organização e o modelo de desempenho da PRM, o que ajudará a compará-lo com o modelo PSP posteriormente.
Die Europäisierung von Strafmilderungsgründen
Authors: Born Patrick Viktor
Published: June 2022

The harmonisation of mitigation causes has so far often received only superficial attention. However, here, as well, divergent approaches are likely to disrupt judicial cooperation in Europe. The author therefore develops an abstract model showing in detail how mitigation causes can be harmonised in a binding manner under European law in order to create a European Minimum Standard in this respect. The consequences of such a binding interpretation are then illustrated on the basis of Article 16 of the Directive on Terrorism. Finally, the concrete effects of such binding interpretation are shown with regard to German, Italian and Spanish rewarding measures and the respective measures are compared with each other.
Deposition of a Porous Cu Layer by Electroplating and Feasibility Evaluation of Cu-Cu Die Attachment by Sinter Bonding Using Thermo-Compression
Authors: Namgoong Doyeop , Lee Jong-Hyun
Published: June 2022

A porous Cu layer was deposited on a dummy Cu die and a dummy substrate, respectively, by electroplating to form a bondline that can endure high temperatures, such as 300 ℃. The plating at a current density of 40 mA/cm2 in a plating solution containing a crystal controlling agent resulted in different porous layers from fine dendritic grains to coarse a typical grains and an increased layer thickness with increasing plating time. Die-attachment sinter bonding at 5 MPa and 300 ℃ in the air by thermo-compression using a 2-min-plated die and substrate after drying a reducing agent absorbed in the layer on a substrate. The boding for 1 min resulted in sufficient bondline shear strength of 26.6 MPa with an excellent microstructure of near full density. Identical bonding with exchanging nitrogen blowing increased the shear strength to 30.3 MPa with significantly reduced oxidation area in the inner edge of the die. The 1- and 3-min samples exhibited lower strength values owing to the local formation of large voids between non-uniform thickness of the deposited layers and the relatively less dense bondline structure, respectively.
Association of Lipid Accumulation Product and Triglyceride-Glucose Index with Metabolic Syndrome in Young Adults: A Cross-sectional Study
Authors: Rajendran Suryapriya , Kizhakkayil Padikkal Anand Kumar , Mishra Sasmita , Madhavanpillai Manju
Published: June 2022

Background: Metabolic syndrome is a cluster of elements linked with type 2 diabetes mellitus and cardiovascular disease (CVD). The early detection of individuals at the risk of developing metabolic syndrome can prevent the development of type 2 diabetes mellitus and CVD. Objectives: This study aimed to evaluate the association of the lipid accumulation product (LAP) and triglyceride-glucose (TyG) index with metabolic syndrome among young adults. Methods: This cross-sectional study included 300 young adults within the age range of 20 - 40 years. Metabolic syndrome was defined according to modified National Cholesterol Education Program Adult Treatment Panel III guidelines. The LAP and TyG index were calculated. Multivariate logistic regression and receiver operating characteristic curve analyses were performed to assess the association of the LAP and TyG index with metabolic syndrome. Results: The LAP and TyG index were significantly associated with metabolic syndrome (P < 0.05). The LAP showed the highest area under the curve (0.882 and 0.905 in male and female subjects, respectively), followed by the TyG index (0.875 and 0.886 in male and female subjects, respectively, at P < 0.0001. The cut-off values for the LAP were 45.65 in males with a sensitivity and specificity of 80% and 46.91 in females with a sensitivity and specificity of 88%. The cut-off points for the TyG index were 8.63 in males with 80% sensitivity and 78.9% specificity and 8.54 in females with 83.3% sensitivity and 79.6% specificity. Conclusions: The LAP and TyG index are significantly associated with metabolic syndrome in young adults. As simple and inexpensive markers, they can be used to identify individuals with metabolic syndrome with high sensitivity and specificity.

Published: June 2022

Background: Heart failure (HF) is recognized as a structural and functional heart complication. Many studies have revealed that anemia plays an ambiguous role in this complication and can be a significant prognostic parameter in HF. In our trial, for clarification of this issue, the relationship between HF and anemia was studied. Methods: In this case-control study, 273 patients admitted to the CCU and post-CCU wards of Dezful Hospital, who were selected by the available sampling method, were studied. In this investigation, among 273 patients with HF, hematological, biochemical, and heart functional parameters were assessed and compared with 89 healthy volunteers. Consequently, the correlation between hematological parameters and functional heart parameters in the patients was evaluated via Pearson’s correlation coefficient. Results: The study subjects were tried to have similar conditions regarding their demographic characteristics. The mean age of the included participants was 53.68 ± 2.17 years. Our data revealed that HF occurs mainly at the age of 50 to 70 years, and patients had an 8.7% mortality risk. Hematocrit (HCT) had a significant reduction in the HF group in comparison to the normal range (P-value < 0.05), and HCT level in healthy subjects (P-value = 0.02). Further, anemia is positively correlated with HF mortality rate and severity of HF indices in patients (P-value = 0.01). Conclusions: The results of our study, consistent with other previous studies, showed that HF patients have a low HCT level, and this reduction is associated with a marked decline in health status indices in HF patients. Also, our results revealed that patients with the lowest level of HCT are at high risk for HF symptoms.
Emerging Inequalities at Animal Farm Tracing the Symbolic Use of Cattle from the Late Neolithic to the Middle Bronze Age in Southern Portugal
Authors: Valera António Carlos
Published: June 2022

The complexity of human-animal relations in later prehistory can be seen in the contrast between the symbolic use of cattle and of other species during the Chalcolithic and Bronze Age in southern Portugal. From a minor symbolic pres- ence among the most common species in the Late Neolithic and Chalcolithic—expressed mainly in rock art representa- tions, animal burials, and rare figurines—cattle emerged with emblematic leading roles in certain funerary contexts in the Middle Bronze Age. The systematic use of cattle limb elements in Middle Bronze Age hypogea in the Serpa area (Beja district, Alentejo), and a decrease in the symbolic use of other animals, suggests a significant change in the cosmological and ideological status of several species within these communities. This study explores the possible symbolic meaning of the growing prominence of cattle within a context characterized by structural changes in several variables of the social system. In doing so, it proposes that the increased use of cattle in funerary contexts is intimately related to the construction of a new social and cosmological order, as well as to a new military atmosphere.
Cattle, Yaks, Traction, and the Bronze Age Spread of Pastoralism into the Mongolian Steppe
Authors: Tumurbaatar Tuvshinjargal , Makarewicz Cheryl A.
Published: June 2022

Cattle traction helped increase crop yields and enhance trade of staple goods among sedentary agricultural communities for millennia, but oxen labor was also important for mobile pastoralists, particularly in Inner Asia where yaks were also herded, and was used to carry materials, portable dwellings, and people. In the Altai Mountains, a rich petroglyph record depicts vibrant scenes of abundant wildlife, people, and also cattle and yaks associated with the Bronze Age, a dynamic period of human movement and technological transmission that spanned the third to mid-second millennium BC. In the Mongolian Altai, cattle and yaks are variously depicted on leads guided by human caretakers, ridden by people, fitted with nose rings or carrying loads, but they are not shown pulling carts or wagons that were used by Bronze Age mobile communities in the western steppe belt. Two-wheeled vehicles appear subsequently in later Bronze Age petroglyphs, and only in association with horses. Although the precise origins of cattle and yak exploitation in Inner Asia remain unresolved in the absence of in-depth biomolecular and zooarchaeological studies, the rock art record strongly suggests the earliest livestock complex in the Mongolian Altai was based on dual cattle and yak herding, and that traction modes involving pack carrying and riding helped facilitate the spread of pastoral nomadism into the region. Even after the introduction and incorporation of horses into the daily and ritual lives of Inner Asian mobile pastoralists, cattle and yak traction remained an important part of herding lifeways, used to transport gers, timber, fodder, water, dung, and people by historic and contemporary herders.

Apuntes para una ontología en red desde Butler y Bottici
Authors: Soler Jana
Published: June 2022

El presente artículo se propone estudiar la red como el referente ontológico fundamental de la existencia en común. A través de un diálogo entre el pensamiento de Judith Butler y la propuesta anarcafeminista de Chiara Bottici, se pretende exponer cómo el desarrollo de una ontología reticular puede apuntar a una propuesta ético-política emancipatoria en términos igualitarios. Para ello, en primer lugar, se analizarán las nociones de interdependencia, vulnerabilidad –Butler– y transindividualidad –Bottici– como condiciones ontológicas fundamentales de la existencia en tanto que relación. En segundo lugar, se vinculará la noción de red con el estudio de la violencia estructural a la que están sometidos los cuerpos de las mujeres. Y, en tercer lugar, se analizará en qué sentido las alianzas entre el anarcafeminismo y la ética de la no-violencia hacen de la red el fundamento de una praxis política emancipatoria basada en la igualdad entre cuerpos.
Healing and reintegration of former child soldiers: A relational resilience perspective
Authors: Wessells Michael
Published: June 2022

In this paper, the author advocates for a psychosocial and community perspective in the work with child soldiers, as torture survivors.
Healing is a priority for former child soldiers, many of whom have survived mass exposures to violence, perpetrated violence, or both. Reintegration programming is often limited by individualized treatment and deficits focused approaches that do not address powerful social barriers to reintegration such as stigma and not having a positive social role. This paper outlines a more holistic, relational approach to reintegration that addresses clinical maladies but also addresses the need for positive social relationships that support young people's resilience and well-being. Underscoring the importance of a multi-disciplinary approach, it calls for the integration of livelihoods supports with mental health and psychosocial supports.
Visions from the past: Reflecting on the history of epidemiological research in the refugee and post-conflict mental health field
Authors: Silove Derrick
Published: June 2022

Epidemiological research has made a major contribution to the knowledge-base in the field of refugee and post-conflict mental health in the last 30 years.  There is a tendency however to question the cultural validity of study findings, or, alternatively, to argue that we have sufficient data to predict the mental health and psychosocial (MHPSS) needs of future populations exposed to mass conflict. This paper attempts to address both issues. Specifically, it is argued that, rather than an indicator of cultural inaccuracy in measurement, the large variation in symptom prevalence rates observed across studies may reflect a genuine difference given the unique profile of risk and protective factors that characterize refugee populations based on their individual histories of conflict and current conditions of resettlement. There are compelling reasons therefore, where feasible, to include epidemiological studies in the comprehensive approach of data gathering in assessing MHPSS needs - and to monitor changes over time -  in current and future populations exposed to mass conflict.
Towards a systematic approach for the treatment and rehabilitation of torture and trauma survivors: The experience of STARTTS in Australia
Authors: Aroche Jorge , Coello Mariano
Published: June 2022

This paper recovers a text written in 1994 that explored and discussed the complex interaction between the psychological and psychosocial sequelae of exposure to highly traumatic situations in the context of organized violence, and the stresses and demands of the exile and re-settlement process of refugees. The effects on the individual, the family and refugee communities were explored, and a model to address these problems from a systemic perspective, involving action at the individual, family, refugee community, mainstream community and mainstream political structures was put forward. The role of approaches such as individual counselling, group work and community development in this framework, and various issues in the practical application of this model were discussed in the context of STARTTS experience. Looking back, almost 30 years later, the paper has renewed value as it shows the founding theoretical principles and the path to what today is one of the most important anti-torture organizations in the world.

Published: June 2022

Regarding its genetic and genomic background, psoriasis is one of the most widely dicovered skin disease, therefore it represents the best example to profoundly understand the pathogenesis of multifactorial skin diseases. The exploration of the genetic background of the disease began in the 1970s, the classical linkage studies were performed in the 90s, and the genome wide association studies (GWAS) studies were launched in the early 2000s, elucidating about one third of the genetic background of the disease. Over the past decade intensive research on underlying missing heritability of the disease has revealed epigenetic mechanisms. It is now certain that interaction of genetic, epigenetic and environmental factors is responsible for the development of the disease.
Genotype-phenotype correlations, functional investigations and therapeutic developments in monogenic skin diseases
Authors:   University of Szeged Department of Dermatology and Allergology Albert Szent-Györgyi Medical Center, Nagy Nikoletta , Széll Márta
Published: June 2022

Genetic and genomic research over the past 10 years resulted in huge advances in the understanding of monogenic skin diseases: 35 new diseases have been described and 131 new pathogenic genes have been identified with our contribution: with the first description of cutaneous teleangiectasia and familial oropharyngeal cancer syndrome and the identification of the USB1 gene. We demonstrated that familial cylindromatosis, multiple familial trichoepitheliomatosis, and Brooke-Spiegler syndrome are not different entities but the clinical variants of the same disease, the CYLD cutaneous syndrome. Regarding therapeutic developments, we contributed to the development of future drug therapies replacing the original cell therapy of intradermal allogeneic fibroblast injections.

Transition metal dichalcogenides (TMDs) have attracted a lot of interest in condensed matter physics research due to the existence of multiple novel physical phenomena, including superconductivity and charge density wave order, and also TMDs provide a unique window for studying the interactions between different ground states. In this work, the electronic structure of 1T-NbSeTe is systematically examined by angle-resolved photoemission spectroscopy (ARPES) for the first time. A van Hove singularity (VHS) is identified at the M point, with binding energy of 250 meV below the Fermi level. Careful analysis is carried out to examine the band dispersions along different high symmetry directions and the possible many-body effect. However, the dispersion kink—a characteristic feature of electron-boson coupling is not obvious in this system. In TMD materials, the van Hove singularity near the Fermi level and the electron-boson (phonon) coupling are suggested to play an important role in forming charge density wave (CDW) and superconductivity, respectively. In this sense, our experimental results may provide a direct explanation for the weakened CDW and relatively low superconducting transition temperature in 1T-NbSeTe. These results may also provide an insight into the charge-density-wave orders in the relevant material systems.

Published: June 2022

The 21st century is an era of information. In recent years, people’s demand for better data storage performance and stronger data processing capacity of memorizer has been increasing, which has prompted continuous improvement and innovation of semiconductor integrated processes and technologies and accelerated the research progress of the next generation of memory devices to break through the limits of Moore’s law. Resistive memory has been regarded as an important candidate for the next generation of non-volatile random access memory due to its main characteristics such as fast reading speed, high storage density, long storage time, low power consumption, and simple structure. Resistive switching effects have been observed in various transition metal oxides and complex perovskite oxides, but the appropriate description of the resistive switching drive mechanism is still an important issue in the development of resistive random access memories. Therefore, further research is very important to clearly explain the phenomenon of resistance switching. With the demand for data storage and sensor applications increasing, materials with excellent ferroelectric and ferromagnetic properties have attracted great attention. The ZnO is an important semiconductor material with excellent optical and electrical properties. Bismuth ferrate (BiFeO3) has received much attention due to its excellent properties in epitaxial and polycrystalline thin films, with hundreds of publications devoted to it in the past few years. The ZnO and BiFeO3 are both important electronic materials and have important application value. Therefore, ZnO/BiFeO3/ZnO structure is adopted in this work to study the resistance switch characteristics. The resistance conversion effect in ZnO/BiFeO3/ZnO structure is measured. In this work, the Ni/ZnO/BiFeO3/ZnO/ITO multilayer nano-film storage device is prepared by magnetron sputtering coating technology. The device is characterized by X-ray diffractometer, scanning electron microscope and other equipment, and its resistance performance is further tested by Keithley 2400. The device exhibits obvious bipolar resistance switching effect, and the resistance switching characteristics of the sample, including switching ratio, tolerance and conductivity, vary significantly with the interference of the applied magnetic field. The bipolar resistance switching effect can be explained by the capture and release of oxygen vacancies trapped inside the material. The effect of magnetic field on Ni/ZnO/BiFeO3/ZnO/ITO thin film device should be attributed to the change of schottky barrier at Ni/ZnO interface, caused by magnetic field.
Stochastic resonance in asymmetric bistable coupled network systems driven by Gaussian colored noise
Authors: Wang Ye-Hua , He Mei-Juan ,   School of Mathematics and Physics, Lanzhou Jiaotong University, Lanzhou 730070, China
Published: June 2022

In this work studied is the synergistic effect of asymmetric bistable coupled network systems under the action of Gaussian colored noise and periodic signal. The system is a network model consisting of a large number of oscillators. The interaction and change between individuals produce complex nonlinear behavior patterns. For further research, firstly, the original N-dimensional system is reduced and approximated by using the mean field theory, the unified colored noise approximation theory and the equivalent nonlinearization method. Secondly, the Langevin equation of simplified model is obtained through the slaving principle by using the two-state model theory to derive the theoretical expression of signal-to-noise ratio. It is found that the system produces the phenomenon of scale stochastic resonance. Finally, the effects of Gaussian color noise parameters, system parameters and periodic signal parameters on the stochastic resonance behavior of asymmetric coupled network systems are discussed. The results show that the increase of Gaussian colored noise correlation time and noise intensity can promote the scale stochastic resonance phenomenon; selecting appropriate coupling coefficient can achieve the optimal stochastic resonance effect. And the stochastic resonance phenomenon of the system driven by the Gaussian colored noise and the Gaussian white noise, respectively, are analyzed and compared with each other. Research result shows that Gaussian colored noise is more conducive to enhancing stochastic resonance phenomenon.

Ultra-Wideband Circular Microstrip Antenna with Hybrid EBG for reduced SAR
Authors: Munde M. M. , Nandgaonkar A. B. , Deosarkar S. B.
Published: June 2022

This article presents a basic ultra-wideband circular microstrip antenna (UWB-CMSA) with partial ground resonating from 2.38 GHz to 12 GHz for handheld devices. The designed antenna covers bands for Bluetooth (2.4 GHz), LTE (2.5/2.69 GHz), WLAN (2.4/3.5/5 GHz), and WiMAX (2.5/3.5/5.5) GHz applications. Specific Absorption Rate (SAR) values of certain bands exceed a limit for UWB-CMSA. The uniplanar spiral unit cell is designed and exhibits phase reversal for 2.4 GHz, 3.5 GHz, and 5.5 GHz. EBG unit cells are placed near the feed for surface wave minimization so as to achieve a reduction in SAR. Furthermore, the EBG structure is placed on the ground plane to analyze the impact, also designs are fabricated and results are compared. Mushroom type M-shaped unit cell is designed which offers phase reversal at 2.3 GHz which is placed near feed in a similar fashion to the earlier spiral one to suppress surface waves also the structure is investigated by arranging it on the ground plane. It is evident that SAR is reduced for all the cases being inspected but for certain bands it exceeds the limit of 1.6 W/kg. A combination of two different unit cells to form a hybrid EBG structure is proposed and evaluated by placing it near the feed. SAR is curtailed by 87.05% at 5.5 GHz.
An Innovative Odd-Power Divider by means of a Triple FinLine Waveguide to Microstrip Transition
Authors: Fantauzzi S. , Valletti L. , Passi D. , Di Paolo F.
Published: June 2022

This paper outlines a novel approach to design a waveguide to microstrip Finline transition, that allows a division by three of the RF power traveling inside a rectangular waveguide. The possibility of obtaining and odd power division of microwave and millimeter wave signals with such Finline transition is completely unexplored yet harbinger of great opportunities. Starting from a 3D CAD model of the structure and continuing with Electromagnetic simulations, the obtained results completely describe a transition able to achieve an almost perfect power splitting by three. Multyphisics simulations, show an intrinsic resistance to vibrations of such transition, allowing it to be installed on aircraft or satellites modules. Thanks to this achievement a total new kind of power devices will come next, exploiting this odd power division in fact, it will be possible to realize different types of microwave amplifiers, increasing the efficiency and decreasing the occupied size. At the Author’s best knowledge it is the first time a divider by three Finline transition is reported in literature.
Highly Directive Array Pattern Synthesis in Different phi Planes of a Large CCRAA Using Array Thinning Technique
Authors: Dubey S. K. , Mandal D. , Mishra A. K.
Published: June 2022

This paper presents a pattern synthesis method of a sizeable concentric circular ring array (CCRAA) of isotropic antennas using Evolutionary Algorithms. In this method, the array is thinned using the optimum set of binary excitations to achieve the desired highly directive pencil beam patterns with lower peak side lobe level(SLL). The half-power beam width and first null beam width is kept constant to obtain such highly directive beam patterns with lower peak SLL. This pattern is not synthesized to a particular azimuth plane rather in four different ' planes from entire azimuth planes. The isotropic elements are uniformly spaced in the concentric ring. The achieved set of optimum amplitudes are constructed with either 1 or 0 using Differential Evolutionary Algorithm(DE), Genetic Algorithm (GA), and Particle Swarm Optimization Algorithm (PSO). These excitations show the state of the elements. The elements are in “ON” state or in “OFF” state depending upon the excitation ‘1’ or ‘0’. It is also helpful to reduce the complexity of the feed networks. The excitations are also verified in the whole range (0o <phi<360o) of ' planes by selecting four phi planes arbitrarily. The outcomes established the superiority of GA and DE over PSO and also the effectiveness of the proposed method.

Stata 16.0 was used for statistical analysis, Chi-square test was used for bivariate analysis, and Poisson regression with robust variances was used for multiple analysis.

Results

The prevalence of patients with a confirmed COVID-19 diagnosis who had CKD and died was 1.42 times the prevalence of mortality in those without CKD. The comorbidities combined with CKD that presented the highest probability of mortality were diabetes mellitus and hypertension.

Conclusions

CKD is associated with a high mortality rate in patients with a confirmed COVID-19 diagnosis. Patients with CKD, diabetes mellitus, and arterial hypertension have a higher prevalence of mortality than those without comorbidities.

Background

Previous studies have shown that Crambe abyssinica and Raphanus sativus are physiologically tolerant to water deficits; however, there is a lack of information on the mechanisms responsible for their tolerance regarding root morphological characteristics. This study aimed to characterize morphological changes in the root system of C. abyssinica and R. sativus subjected water deficit, as well as to identify the responses that improve tolerance and post-stress recovery capacity of these plants.

Methods

Independent experiments for each specieswere performed in a controlled greenhouse, where plants were randomly set in a randomized block design with five replicates. Plants of C. abyssinica and R. sativus were cultivated in pots and exposed to well-watered treatment (WW; 90% water holding capacity–WHC of the substrate) or water deficit (WD; 40% WHC) conditions, at 28 days after planting. The plants were kept under WD for 7, 14, or 21 days with rehydration soon after each episode of water deficit. Assessment of water relations, biomass allocation, leaf and root system morphological characteristics and gas exchange were performed after each period of water deficit and 48 h after rehydration.

Results

The water deficit reduced the water status of both species, and morphological and biomass allocation were not recovered after rehydration. Photosynthesis of C. abyssinica decreased with prolonged water deficit, which was also not recovered after rehydration. In R. sativus, photosynthesis was not altered by WD for 21 days, and a higher WUE was recorded. Root morphology of R. sativus was mainly affected at 14 days of WD, while the traits related to very fine roots increased at 21 days of WD, when compared to WW plants. Thus, R. sativus has shown greater tolerance to water deficits mainly due to the presence of very fine roots throughout the period of stress, when compared to C. abyssinica in which the fine roots predominated.

Introduction: Periodontal disease leads to the loss of supporting structures of the tooth. Recent years have witnessed the evolution of many regenerating materials that have shown to be effective in regenerating the loss structures. Aim: To evaluate and compare clinically and radiographically the efficacy of Platelet Rich Fibrin (PRF) and Nanocrystalline Calcium Sulphate Bone Graft (NanoGen®) in the treatment of intrabony defects. Materials and Methods: A split mouth randomised clinical study was done in the Department of Periodontology D.A.P.M.R.V. Dental College Bangalore from November 2018 to May 2020. In this study, 30 surgical sites were selected from 15 chronic periodontitis patients American Academy of Periodontology (AAP, 1999) of age between 35-65 years and with interproximal probing depth ≥5 mm following phase I therapy and radiographic evidence of intrabony defects ≥3 mm deep. They were divided into two groups: Group I (n=15) received open flap debridement with Nanocrystalline Calcium Sulphate (nCS) and Group II (n=15) open flap debridement with PRF. Clinical parameters assessed were Gingival Index (GI), Plaque Index (PI), Gingival Recession (GR), Probing Pocket Depth (PPD) and Clinical Attachment Level (CAL). Intragroup was compared using Repeated Measures of ANOVA followed by Bonferroni's Post hoc Test and intergroup was compared using Independent Student Test. Results: Total 15 patients were selected in each group of which 10 were male and 5 were female patients. Mean age of the patients was 39.3 years. There was significant reduction in GI (p-value=0.04,PPD (p-value=0.04) and gain in CAL (p-value=0.04) in group I. The mean difference in CAL was also statistically significant in group II (p-value=0.01).The mean difference PI was not statistically significant between baseline and three months and baseline and six months in both groups. GR increased from baseline to three months and remained same at six months (p-value for group I and group II=0.36) in both groups. On intergroup comparison, group I (nCS) showed better improvement in clinical parameters like PPD (p-value=0.01), CAL (p-value=0.01) and BF (p-value=0.002) at all time intervals compared to group II (PRF). Conclusion: There was improvement in all clinical parameters except GR in both groups. So both can be used as regenerative materials. But based on this study nanocrystalline calcium sulphate bone graft can be preferred over PRF as a regenerative material.

Introduction: Olfactory fossa is an important structure in the anterior skull base. It is made of Lateral Lamella of Cribriform Plate (LLCP) and fovea ethmoidalis which are very delicate parts that can get damaged during surgical procedures causing numerous serious complications. To avoid such complications, the knowledge of anatomical variations of these parts is mandatory. As there are very few studies which have used Cone Beam Computed Tomography for evaluation of olfactory fossa, we have assessed the olfactory fossa with the help of Kero’s and Gera’s classification for lateral lamella of cribriform plate. Aim: To evaluate the anatomy of olfactory fossa using Cone beam computed tomography. Materials and Methods: A retrospective observational study was conducted in the Department of Oral Medicine and Radiology, from 1st January 2021 to September 2021. CBCT scans of 107 adults were analysed to evaluate the height of lateral lamella of cribriform plate according to Kero’s classification and the angle between the LLCP and the true horizontal plane according to Gera’s classification. Comparison of height of lateral lamella (mm) and Gera angle (degree) among right and left sides were done using Student’s Independent t-test. The comparison of Gera angle with Kero’s type was analysed by one way Analysis of Variance (ANOVA) test. Chi-square test was performed to assess categorical data on the right and left sides. Results: A total of 107 CBCT scans consisting of 59 males (55.14%) and 48 females (44.86%) were included in the study. The mean age of the study population was 31.60±11.17 years. Kero’s type II (69.6%) and Gera’s class II (92.1%) LLCP were found to be most commonly seen. The Gera angle on right side (60.26±9.84) was greater than on left side (56.38±10.16) which was statistically significant (p-value=0.005). On right side, Kero’s type II was more common in males (71.2%) and on left side, Kero’s type II was more common in females (77.1%). Conclusion: Kero’s type II Olfactory fossa (OF) was found as most common type, with no significant difference between gender and /or side. Similarly, class II Gera angle was most common and the values were higher on right side.

Introduction: Image-guided percutaneous transthoracic needle biopsy of mediastinal masses is usually safe and effective technique for obtaining tissue for diagnosis and early decision can be taken for effective management. Aim: The purpose of this study was to know the efficacy of different investigative methods for diagnosis of mediastinal masses and to analyse various cytomorphological forms. Materials and Methods: This was a retrospective observational study conducted at Pandit Raghunath Murmu Medical College, Baripada from January 2019 to June 2020. Retrospective review of all Ultrasonography (USG) and Computed Tomography (CT)- guided percutaneous aspirations of the anterior mediastinum mass. Relevant data regarding patient demographics, imaging characteristics of aspirated masses, presence of complications, and subsequent surgical intervention were collected. Cytology and core biopsy pathology results were recorded. The qualitative data were compared using Chi-square test with Yate’s correction. Results: This study included 35 patients (25 male, 10 female). Highest incidence was noticed in anterior mediastinum (n=26, 74.3%) followed by superior (n=4, 11.4%) and posterior mediastinum (n=3, 8.6%). Most of the cases were malignant (n=28; 80%) and Non Hodgkin Lymphoma (NHL) was most common diagnosis (n=10; 28.6%). Radiology yielded the correct diagnosis in 25 out of 35 patients (71.4%). Core biopsy was obtained in six cases and all the cases were diagnosed cytologically with 100% accuracy. There was statistically significant difference between the radiological and cytological diagnosis. The complication rate was minimal (2/35), both were the case of pneumothorax. Conclusion: Image-guided percutaneous aspiration is a safe diagnostic procedure with high diagnostic accuracy in aspiration cytology than radiology. Highest diagnostic accuracy was seen in non hodgkins lymphoma and it can potentially obviate more invasive procedures.
