Published: July 2022

Os ameloblastomas são tumores benignos de origem odontogênica com um alto poder destrutivo e que frequentemente acometem região de mandíbula. Após a suspeita, alguns exames são realizados para que se obtenha o diagnóstico, como exames imagenológicos, histopatológicos e imunoistoquímicos. A punção aspirativa, ordinariamente utilizada como manobra semiotécnica para a caracterização da natureza da lesão (cística ou sólida), pode ter importância na elucidação diagnóstica destes casos em um exame citopatológico. Este trabalho relata o caso clínico de um paciente do sexo masculino de 28 anos com queixa de um “cisto” com aumento de volume e evolução de oito meses em região anterior direita da mandíbula. Para o diagnóstico, foi realizada uma punção aspirativa na região do tumor, primariamente, e uma biópsia incisional sequencialmente, os materiais coletados foram encaminhados para exames citopatológico e histopatológico, respectivamente. O laudo do primeiro exame foi sugestivo de ameloblastoma, no qual pode ser confirmado no exame histopatológico. O tratamento foi a remoção do tumor com margem de segurança. O relato mostra a importância do exame citopatológico como ferramenta de elucidação diagnóstica de lesões expansivas nos ossos maxilares. A punção aspirativa para a coleta do material para este fim, é uma técnica simples, rápida e barata. Quando bem executada, seu resultado é satisfatório e pode ter grande valor diagnóstico.

Introdução: Os modeladores de resina composta (MRC), comumente empregados, adesivos dentinários ou resinas de baixa viscosidade, atuam facilitando a inserção e a escultura do material restaurador, podendo beneficiar o escoamento, conter a incorporação de bolhas e diminuir o insucesso da restauração. Esta técnica é útil, especialmente, no caso de grandes restaurações. Objetivo: analisar, por meio de uma revisão da literatura, o conceito de modeladores de resina composta, os materiais mais utilizados e eficazes, além das consequências ópticas e físicas dessa técnica. Metodologia: Foi realizada uma revisão da literatura, por meio de buscas nas bases de dados PubMED, BVS e Scielo, sendo selecionados estudos relacionados ao tema, do período de janeiro de 2016 a junho de 2021. Para escolha dos artigos, foram empregados os seguintes descritores: Composite resins, Dentin-bonding agents, Color stability e Dental Materials.  Resultados: A maioria dos estudos testaram os sistemas adesivos Single Bond 2® (SB) e Adper Scotchbond® (SBMP), no qual observou-se eficácia em ambos os tipos na obtenção de estabilidade de cor e, no caso do SBMP, menor solubilidade e degradação da resina composta (RC). Ademais, os espécimes preparados com modeladores apresentaram menor incorporação de pigmentos e menor aumento no grau de opacidade. Conclusão: Os modeladores de resina composta facilitam a inserção e a escultura do material restaurador, além de permitirem a maior coesão dos incrementos do compósito, reduzindo a degradação deste. Outrossim, podem propiciar maior estabilidade de cor e menor suscetibilidade ao manchamento.

O câncer bucal permanece, apesar dos avanços, como um problema de Saúde Pública mundial. Para que o prognóstico seja favorável, a lesão deve ser identificada em estágio inicial, levando em consideração suas características clínicas. O presente trabalho objetivou analisar casos clínicos de pacientes acometidos pelo Carcinoma Espinocelular e comparar o grau de conhecimento dos graduandos de Odontologia frente a um diagnóstico de câncer oral. Foi investigada história clínica de prontuários de pacientes com este diagnóstico, respeitando a sua identidade, e realizado um questionário com estudantes para comparar o grau de conhecimento com as características inerentes da nossa região em relação ao câncer bucal. Os resultados obtidos vão de acordo com os artigos estudados, levando em consideração que o Câncer atinge, geralmente, homens entre 40 a 80 anos, que possuem o hábito de beber e fumar. A área mais acometida foi língua, com lesões ulceradas e irregulares em fumantes. O conhecimento dos estudantes de Odontologia foi satisfatório, de acordo com as características clínicas encontradas nos casos estudados. Conclui-se que diagnosticar o câncer oral em estágio precoce é o meio mais efetivo de reduzir a morbidade, dificuldade e extensão do tratamento. Desse modo, o estudo visou relatar o quão importante é o Cirurgião Dentista no conhecimento clínico da lesão, já que esse pode ser o primeiro profissional a se deparar com essa doença. Ações de saúde pública também são indispensáveis para alertar a população sobre os fatores de risco que acarretam o aparecimento da doença.

Published: July 2022

Purpose - The purpose of this paper is to present the findings of the study on optimizing solvency margin in family Takaful and life insurance institutions in Malaysia.Method - The population of this study is family Takaful and life Insurance Institutions in Malaysia during the period 2010 - 2019. The selection of samples in this study uses the purposive sampling method and selected 11 family Takaful and 14 life Insurance Institutions. The data were analyzed using Data Envelopment Analysis.  Result - The results showed that for from 2010 to 2019, the family Takaful operators’ efficiencies are improving, whilst the life insurers have become less efficient even though their efficiency score is higher than the family Takaful operators. In terms of the optimum size (i.e., scale), the results are reversed which means that the family Takaful operators are still not at the optimum size but once they reach there, they could improve their efficiency substantially. However, for both family Takaful operators and life insurers, 2019 seems to dip their efficiency in terms of pure technical and also scale.Implication - The results of this research open a new way of measuring the efficiency of family takaful and life insurance not only in Malaysia but can be generalized to measure the efficiency level of family takaful and life insurance in general.Originality - This research is the first study that used the combination of inputs and outputs specifically for the family Takaful and life insurance institutions in Malaysia.

Authors: Bajpai A.
Published: July 2022

Polymer nano-composites consist of two or more constituents with at least one being of nanoscale dimension. Being naturally abundant, affordable, non-toxic and biocompatible, clay-based minerals and biopolymers are advantageous to afford eco-friendly nanocomposites, especially useful for biological applications. Starch, a common polysaccharide, finds traditional use in the food industry, and has recently become relevant in several advanced technologies. Nontronite, an iron rich smectite clay, still remains underexplored in the context of nanocomposite preparation. This book chapter attempts to provide a brief overview of syntheses and applications of nanocomposites based on nontronite, starch and polysaccharide-clay.

Published: July 2022

Background Coarctation of the abdominal aorta (AoA) is a very uncommon condition, accounting for 0.5-2 percent of all aortic stenosis cases. We present an 11-year-old child who has been diagnosed with abdominal aorta coarctation. Case Illustration An 11-years old boy complained about dizziness since 1.5 years ago with hypertension. He underwent hypertension treatment for 1.5 years with a pediatrician but there is no improvement in his blood pressure. His current blood pressure was 150/95 mmHg in upper extremities and 120/80 mmHg in lower extremities with three antihypertensives drugs. We found bruit in the abdomen and decreases pulse in lower extremities. An echocardiogram shows no congenital defect. The first was on suspicion of renal stenosis and underwent ultrasonography of the abdomen but was not conclusive. Computed Tomography Angiographic (CTA) showed severe stenosis in the abdominal aorta on level thoracal 11-12. Aortogram shows significant stenosis in the abdominal aorta with a pressure gradient was 47 mmHg. He underwent percutaneous transluminal angioplasty with BMS self-stent implantation. At two months of follow up his blood pressure target was achieved with a minimal dose of oral antihypertensive drugs Discussion How to diagnose coarctation of the abdominal aorta is still challenging and often underdiagnosed. Patients with young age and persistent hypertension should be more careful in diagnosis. A bruit in the abdomen with a weak pulse in the lower extremity raises suspicion of Coarctation of the Abdominal Aorta. An angioplasty procedure, either with or without a stent or a surgery might be used as the primary therapy.
Lisa Vancauwenberghe Performing the City: Urban Discourses and the Representation of Italian Cities in the Music Videos of Italian rapper Capo Plaza
Authors: Vancauwenberghe Lisa
Published: July 2022

This article analyses how various contemporary urban discourses are performed and negotiated in the visual work of Italian hip hop artist Capo Plaza. The modern metropole, the postmodern society of the spectacle, tourist authenticity discourses around ‘couleur local’ and a focus on ordinary life are all dealt with in his music videos. By analyzing how cinematic strategies and choices are able to bring those images into dialogue, as well as subvert them, this article aims at an exploration of this new medium as a reincarnation of the genre of the city symphony. As his work deals with both the small southern city Salerno and the metropole Milan, questions of scale and the international urban imagination, come into play as well.
Операторная форма обобщенной оптической теоремы для волновых задач
Authors: Апресян Л.А.
Published: July 2022

The operator form of the generalized optical theorem (OT) obtained earlier for the scalar wave equation is extended to the case of electromagnetic radiation, as well as other wave equations. It is shown that in the transition from the operator to the usual OT, instead of the "forward" scattering amplitude, the diagonal matrix element of the T-scattering operator corresponding to the incident wave appears. The transitions to known forms of OT following from operator OT as special cases are also illustrated.

The possibilities of organizing a repetitively pulsed process with given frequency characteristics in a cavity of constant volume with an external energy supply to the working gas mixture are considered. Modelling of gas-dynamic and thermal processes is carried out using the numerical solution of the conjugate heat transfer problem. The gas medium is described on the basis of a viscous compressible gas model. To find the temperature field in the walls of the structure, the equation of non-stationary heat conduction is solved. The conjugation of temperature fields in a gas and a solid is carried out using an iterative procedure. In the calculations, the geometrical parameters of the cavity, the density of the energy supply, the initial pressure, and the composition of the working mixture are varied. The results of calculations obtained in the framework of the one-dimensional and two-dimensional formulation of the problem under the action of both a single pulse and a series of pulses are compared. The results obtained demonstrate the possibility of implementing the required frequency characteristics of the process for given geometric and energy parameters.

This work is devoted to determining the azimuthal ion rotation velocity in a reflex discharge with a thermionic cathode. For the experimental determination of the ion velocity, a Mach probe with directional particle collection was used. The Mach probe rotation velocity measurements are compared with the drift speed in crossed ExB fields, where the radial electric field is measured with an emissive probe. The rotation of the plasma was found to be predominantly due to this drift, corrected for centrifugal effects. One of the important results of the work is the determination of the ion temperature. The obtained value Ti=0.12 eV, agrees with the ion temperature estimates in works with similar experimental conditions. A general parameter has been obtained that makes it possible to estimate the necessity to take into account centrifugal effects under given conditions.

Published: July 2022

The mechanism of anode-initiated breakdown in liquid organic dielectrics with long molecular chains is proposed on the basis of the experimental data on high velocities of the breakdown channel propagation in organosilicon and organofluorine liquids (~10^{7} cm/s), which is comparable to that obtained earlier in crystals in the same conditions. The high velocities of the anode-initiated breakdown channel are satisfactory explained within the model of the cascade Auger transitions, developed for the crystalline materials. According to this model, velocity of the breakdown channel propagation is proportional to the electrical field strength. The time delay in breakdown channel formation relative to the voltage pulse front does not exceed ~5·10^{-10} s within the margin of error.

The features of spark plasma sintering of submicron Al2O3 powders with different contents (0, 0.5, 1.5, 5 vol.%) of -SiC nanoparticles have been studied. The microstructure and hardness of Al2O3 + 5 vol.% SiC ceramics obtained by sintering Al2O3 powders with -SiC particles of various types (nanoparticles, submicron particles, fibers) have been studied. Sintering was carried out at heating rates (Vh) from 10 to 700 °C/min. The sintering process of Al2O3 + SiC ceramics with low heating rates (Vh = 10–50 °C/min) has a complex three-stage character, with a flat area in the temperature range of 1200–1300 °C. At high heating rates (Vh > 250 °C /min), the usual three-stage character of sintering is observed. The analysis of temperature dependences of compaction was carried out using the Young-Cutler model; It was found that the kinetics of powder sintering is limited by the intensity of grain boundary diffusion. It is shown that the dependence of the hardness of Al2O3 + SiC ceramics on Vh has a nonmonotonic character, with a maximum. In the case of pure alumina, an increase in Vh leads to a monotonic decrease in hardness.

As one of the approaches to improve p-HEMT, we studied the effect of misorientation of GaAs substrates on the surface morphology, structure, and electrical properties of pseudomorphic heterostructures, as well as the parameters of transistors based on them. In a single technological cycle, heterostructures were formed on vicinal substrates with (100) orientation and misoriented by 2° to (110) by the method of MOCVD (MOCVD) in a single technological cycle. It has been established that on misoriented substrates, the growth of structurally consistent and stressed epitaxial layers occurs according to a layered-step mechanism with the formation of macrosteps. On vicinal substrates, the formation of monatomic growth steps was observed. The comparative characteristics of p-HEMT obtained using two types of substrates are considered.

Leucosapphire (c-LS) structure and transmission in visible after surface treatment in 90%H2-10%N2 RF discharge are studied. According to AFM, the number of scratches of the mechanically polished surface decreased significantly after removal of about a 300 nm layer (exposure time of 12 h) under unchanged rms of roughness. According to TEM, a two-layer structure formed in the near-surface region consists of an outer 10 nm amorphous layer followed by a crystalline layer of 40–50 nm with a high defect density. The c-LS transmission in the angle of 400–1000 nm either slightly increased or remained unchanged. The demonstrated transmission stability during exposure in 90%H2-10%N2 RF discharge allows us to consider the plasma sputtering as a promising technique for cleaning contaminated windows protecting first mirror of divertor Thomson scattering being developed for ITER divertor.

La Corte Constitucional de Colombia, por medio del Auto 004 de 2009 y en el marco de la superación del estado de cosas inconstitucional declarado en la Sentencia T-025 de 2004, ordena, entre otras acciones, la formulación e iniciación de la implementación de planes de salvaguarda étnica "para cada uno de los pueblos identificados en la presente providencia". Son 34 pueblos indígenas, que incluyen los 4 asentados en la Sierra Nevada de Santa Marta: Arhuaco, Kankuamo, Wiwa y Kogui. No obstante, a pesar de que hace más de un lustro sus versiones se encuentran disponibles en el Ministerio del Interior, la noción de desarrollo comunitario indígena choca con los indicadores de desarrollo económico de los entes gubernamentales, que se alinean con la política macroeconómica capitalista. La metodología híbrida que aquí se expone, construida participativamente con las comunidades descritas, facilita la generación de proyectos desde su visión ancestral para que la innovación y el conocimiento científico se ponga al servicio del fortalecimiento de la autonomía, el autogobierno y las economías comunitarias. Se genera así una ruta metodológica hacia la inclusión de los pueblos ancestrales en la sociedad colombiana, en sintonía con su búsqueda permanente y continua del buen vivir.

Published: July 2022

Background

Atopic dermatitis is a pruritic chronic condition associated with significant sleep disturbance, inattention, and sometimes behavioral problems. Enhancing resiliency in children with atopic dermatitis may promote coping strategies to improve quality of life. Positive psychology is one strategy that can be used to strengthen resiliency.

Objective

Our objective was to identify positive psychology concepts mentioned by children with atopic dermatitis and their parent to inform strategies to strengthen resiliency in children with atopic dermatitis.

Methods

A total of 20 patient-parent dyads were interviewed to share their experience with atopic dermatitis to help develop a novel psychologic intervention for atopic dermatitis. Patients were 8 to 17 years old and diagnosed with atopic dermatitis. Trained coders analyzed transcripts using a coding dictionary developed based on Seligman’s PERMA (positive emotion, engagement, relationships, meaning, and accomplishment) model of positive psychology. The frequency of unprompted mentions of PERMA themes and relevant quotations was captured. Transcripts were also separately coded for resiliency, which is the ultimate goal of PERMA.

Results

Positive psychology concepts were mentioned by 100% (20/20) of children and 95% (19/20) of parents. Engagement and relationships, both negative and positive aspects, were the most common unprompted PERMA themes mentioned by children (14/20, 70%) and parents (13/20, 65%). Emotion elicited the most negative comments from children (19/20, 95%) and parents (17/20, 85%). When analyzed for resiliency, 8 participants were identified with at least one resiliency code. On average, participants with a resiliency code mentioned PERMA concepts 9.1 (SD 4.7) times compared to those who mentioned none (mean 5.9, SD 4.6) (P=.14). When participants were stratified by disease severity, on average, more positive psychology concepts were mentioned by patients with mild atopic dermatitis (mean 13, SD 3.0) than those with moderate symptoms (mean 6.2, SD 4.9) or severe symptoms (mean 6.1, SD 4.0) (P=.03).

Conclusions

Among PERMA themes, engagement and relationships are the two most commonly mentioned categories for children with atopic dermatitis. Strategies targeting PERMA such as affirmations and positive reframing may improve psychosocial well-being and resiliency in pediatric atopic dermatitis. Future directions will look at incorporating “positive medicine” into atopic dermatitis treatment to not only relieve symptoms but also strengthen positive aspects of life.
Peruraian Anaerobik Termofilik Palm Oil Mill Effluent dengan Variasi Konsentrasi Substrat

Published: July 2022

High utilization of palm oil in Indonesia corresponds to palm oil mill effluent (POME). The POME has chemical oxygen demand (COD) of up to 100.000 mg/L, which can pollute the ecosystem if not adequately treated. One of the methods to manage POME is anaerobic thermophilic digestion. The advantage of this method is the production of methane gas which is a form of alternative energy. Substrate concentration affects anaerobic digestion. This preliminary experiment aims to evaluate the performance of anaerobic thermophilic digestion on various POME concentrations at 55 °C. The anaerobic digestion was run with 16.000, 11.000 and 5.000 mg sCOD/L substrate concentrations. Digested cow manure (DCM) was used as inoculum. The process was running in a continuous system after 7-days of acclimatization of the batch system. The result shows that 16.000 and 11.000 mg sCOD/L concentrations produced more methane, but the methane yield was not statistically significant with the Tukey test (p=0,05). The POME with a 5.000 mg sCOD/L concentration produced less methane and plummeted after day 85. The lower methane production at lower substrate concentration was due to the low sCOD availability and high volatile fatty acid (VFA) accumulation which inhibited the methane production.

A B S T R A C TPalm oil mill effluent (POME) is wastewater with high organic matter, the raw material of biogas production through anaerobic digestion. In anaerobic digestion, the washout effect frequently becomes a problem, along with the increasing organic loading rate (OLR) in a continuous system. Therefore, the addition of immobilization media was carried out to reduce this risk. This study aims to evaluate the effect of immobilization media type and arrangement on the performance of thermophilic anaerobic digestion of POME. Two immobilization media were evaluated,i.e., carbon fiber textile (CFT) media and natural zeolite particles. The anaerobic process performance was determined by measuring the concentration of volatile fatty acids (VFAs), soluble chemical oxygen demand (sCOD), and methane (CH4) yield. This study indicated that the immobilization media led to higher CH4 yields than the reactor without immobilization media. The CH4 yield of the reactor with natural zeolite was 0.3487 L/g sCOD, 0.3050 L/g sCOD in the reactor with CFT media, and 0.2873 L/g sCOD in the reactor without immobilization media. In addition, only natural zeolite can maintain reactor performance when the temperature accidentally increased with a recovery period of 14 days.Keywords: anaerobic digestion; biogas; carbon fiber textile; natural zeolite; POME.ABSTRAKPalm oil mill effluent (POME) merupakan limbah cair dengan kandungan organik yang tinggi sebagai bahan baku produksi biogas melalui peruraian anaerob. Dalam peruraian anaerob, efek washout selalu menjadi masalah seiring dengan meningkatnya organic loading rate (OLR) pada sistem kontinu. Oleh karena itu, dilakukan penambahan media imobilisasi untuk mengurangi risiko tersebut. Penelitian ini bertujuan untuk mengevaluasi pengaruh jenis dan pengaturan media imobilisasi terhadap kinerja peruraian anaerob termofilik POME. Dua media imobilisasi yang diuji yaitu media jenis carbon fiber textile (CFT) dan media berupa partikel zeolit alam. Kinerja proses anaerob ditentukan dengan mengukur konsentrasi asam lemak volatil (VFA), soluble chemical oxygen demand (sCOD) dan yield metana (CH4). Hasil penelitian ini menunjukkan bahwa reaktor dengan media imobilisasi menghasilkan yield CH4 yang lebih tinggi dibandingkan dengan reaktor tanpa media imobilisasi. Yield CH4 reaktor dengan zeolit alam sebesar 0,3487 L/g sCOD, 0,3050 L/g sCOD pada reaktor dengan media CFT dan 0,2873 L/g sCOD pada reaktor tanpa media imobilisasi. Selain itu, hanya zeolit alam yang dapat mempertahankan performa reaktor saat mengalami gangguan peningkatan suhu secara tiba-tiba dengan masa recovery selama 14 hari. Kata kunci: biogas; carbon fiber textile; peruraian anaerobic; POME; zeolit alam.

Background and objectives

High tacrolimus intrapatient variability has been associated with inferior graft outcomes in patients with kidney transplants. We studied baseline patterns of tacrolimus intrapatient variability in pediatric patients with kidney transplants and examined these patterns in relation to C1q-binding de novo donor-specific antibodies.

Design, setting, participants, & measurements

All tacrolimus levels in participants who underwent kidney-only transplantation at a single pediatric center from 2004 to 2018 (with at least 12-month follow-up, followed until 2019) were analyzed to determine baseline variability. Intrapatient variability was defined using the coefficient of variation (SD/mean ×100%) of all samples in a 6-month moving window. Routine de novo donor-specific antibody measurements were available for a subgroup of patients transplanted in 2010–2018. Cox proportional hazards models using tacrolimus intrapatient variability as a time-varying variable were used to examine the association between intrapatient variability and graft outcomes. The primary outcome of interest was C1q-binding de novo donor-specific antibody formation.

Results

Tacrolimus intrapatient variability developed a steady-state baseline of 30% at 10 months post-transplant in 426 patients with a combined 31,125 tacrolimus levels. Included in the outcomes study were 220 patients, of whom 51 developed C1q-binding de novo donor-specific antibodies. De novo donor-specific antibody formers had higher intrapatient variability, with a median of 38% (interquartile range, 28%–48%) compared with 28% (interquartile range, 20%–38%) for nondonor-specific antibody formers (P<0.001). Patients with high tacrolimus intrapatient variability (coefficient of variation >30%) had higher risk of de novo donor-specific antibody formation (hazard ratio, 5.35; 95% confidence interval, 2.45 to 11.68). Patients in the top quartile of tacrolimus intrapatient variability (coefficient of variation >41%) had the strongest association with C1q-binding de novo donor-specific antibody formation (hazard ratio, 11.81; 95% confidence interval, 4.76 to 29.27).

Conclusions

High tacrolimus intrapatient variability was strongly associated with de novo donor-specific antibody formation.
Fed up of and Fed up with in Two Corpora
Authors: Kang Namkil
Published: July 2022

The main purpose of this paper is to demonstrate that fed up of and fed up with are low similarity synonyms. A point to note is that fed up with was always favored over fed up of in twenty countries’ web from 2010 to 2022. A further point to note is that the figure of fed up of and fed up with reached a peak in 2019 and 2020, respectively. When it comes to the COCA, fed up of and fed up with have the same property in the magazine genre, whereas they have different properties in the other seven genres. This in turn implies that fed up of is 14.28% the same as fed up with in eight genres. With respect to the Euclidean distance, fed up of is the nearest to fed up with in the TV/movie genre. Quite interestingly, the NC shows that fed up of people and fed up with people are the most preferred ones in twenty countries’ web. Finally, with respect to the NC, it is interesting to note that 18.18% of forty four nouns are the collocations of fed up of and fed up with. It can thus be inferred that fed up of and fed up with are low similarity synonyms.
Surface Fault Detection in 3D Printed Objects Using Deep Learning
Authors: A Aditya Sharma
Published: July 2022

Abstract: Robots and machines in Industry 4.0 must be able to operate efficiently and autonomously. They should work in a way that makes the work efficient and substantially error-free. A key component of Industry 4.0, additive manufacturing, or 3D printing, is bringing forth a wave of innovation in daily life by creating everything from toys to furniture to screws. The enthusiast typically uses 3D printing. To create 3D objects for private or commercial usage, various printing techniques have been developed. These techniques include fused deposition modelling (FDM), stereolithography (SLA), digital light processing (DLP), and selective laser sintering (SLS). Despite the enormous potential for AM techniques to produce unique parts on demand and with little material waste, 3D printing is not typically used in mass production. This is due to two reasons. The cost of printing is too high, and since 3D printing is typically a labour-intensive process, it would not be practical to implement it in a mass production setting. Secondly, there is no quality assurance process other than manual inspection. By applying Deep Learning to automate the QC control component of 3D printing, we hope to solve the second issue. Our research demonstrates an in-situ monitoring strategy without causing damage that can find surface flaws in 3D-printed products. We suggest a deep learning-based method in this work to assess the quality of a 3D-printed object. Deep Convolution Neural Network and Deep Convolution Neural Network with Random Forest algorithm are the first two approaches used to do this.
Automation of End-to-End Testing and Their Importance
Authors: R Soundarya , Srinivas B. K.
Published: July 2022

Abstract: End to end testing, to put it very simply, is a sort of software testing to ascertain whether software is behaving as planned. An End to end test is a way which tests every layer of the application, including the user interface, the browser (and compatibility with it), the network, the server, the APIs, the codebase, any third-party integrations, and any hardware—the whole kit. As there were a number of drawbacks in the manual testing, in order to overcome these drawbacks automation testing has been proposed.

Authors: M Asma
Published: July 2022

Abstract: The rapid development of object detection algorithm as led to its widespread application in security, such as facial recognition and crowd surveillance. However, real-time tracking of an individual is very challenging, especially in crowded places where the person might be in part or entirely occluded for some period. Hence, this paper objective is to create abnormal activity detection in public places focusing only on people. This system does not just detect a person in real-time but in addition, uses the information it as learned to track the trajectory of the person until they exit the frame of the camera. The system uses the algorithm called YOLO for the person detection. The system was able to successfully detect the abnormal activity in public places and detect crowded group of people in live
Effect of Base Isolation using LRB on Stepped Building
Authors: Kumar Sooraj , Jaiswal Ganesh
Published: July 2022

Abstract: The base isolation design strategy uncouples the superstructure from the foundation, reducing the effects of earthquake ground motion. The structure is isolated from the ground motion by a flexible base. Installing base isolators in columns. The structural response accelerations are usually less than the ground motion acceleration. In general, base isolation reduces storey shear and acceleration while simultaneously increasing time period, and storey drift, allowing rigid buildings to be more flexible by dispersing energy to the foundation. The basic seismic isolation design provides a shielding technique, allowing the structure to function without harm even after significant earthquakes. The current study explores the seismic effects of a G+6 stepped building with an LRB isolator. An isolator with a lead rubber bearing was used. E-tabs is used to conduct the base isolation study and seismic analysis. The reaction of the structure, lateral shear force, time period, and base shear, was observed. This paper presents time-history analysis and performance assessment analyses on a base isolated stepped building using Bhuj Earthquake ground motion data.

Authors: Majumdar Soumya
Published: July 2022

Abstract: Many dictionary applications (Online or offline) are available in the market but are not so helpful. They complicate the problem more than solve it in many cases; the dictionary refers to a complex solution, which leads to failure of referencing. Referencing tools are now not available in the market. A Bi-lingual tool can reference two contents of different languages in Paragraph, Line, and Word/Phrase levels.
