Published: July 2022

Introduction:Forensic expertise, including dental ide ntification and expertise in civillitigation cases related to dental malpractice and injuries mostly count on dental records.Comparison of dental data obtained from the deceased person with dental data obtained bythe dentist from the person’s life is a primary method of identification through dentalevidence.Materialand Methodology: In all, 180 dentists participated in an online survey. Questionscovered general information on dentists, maintenance of dental records, and knowledge oflegal requirements and forensic odontology.Results:66.6% of dentists said that they update patients’ data on every visit. 86.6% of dentistswere aware of the use of Dental records in Forensic Odontology. 89.9% of dentists were notaware of how they should present the data when asked by the legal authority whereas only10.1% of Dentists were aware of how they are supposed to provide the data. The percentageof dentists who knew how long they are legally mandated to keep patient records showed asignificant difference (p<0.0 5) between BDS (Bachelors of Dental Surgery) and MDS(Masters of Dental Surgery) practitioners.Conclusion:Dentists being aware of forensic odontology, still lack the information about thelegal aspects of it. Forensic odontology should be included in the curriculum as a separatesubject to improve knowledge at the grassroots level. The focus should also be improvedtowards raising the awareness among private practitioners regarding the practical aspect offorensic odontology.

Published: July 2022

Background: Vascular anomalies are congenital defects in vasculogenesis. They are classified into vascular tumors (hemangiomas) and vascular malformations (venous malformations, arteriovenous malformations, lymphatic malformations). Sometimes, lymphatic channels may be evident in hemangiomas. Depending on predominant component, it will be categorized either as hemangiolymphangiomas or lymphangiohemangiomas, vice versa is true for lymphangiomas. Hemangiomas of the oral cavity are not commonly observed though head and neck are common sites.
Case presentation: The patient was a 13-year-old female who presented herself to the Department of Oral and Maxillofacial surgery at Dental college, with the complaint of swelling in upper lip since 12 years. The swelling was soft in consistency and bluish in colour. The lesion was diagnosed as hemangioma after clinical examination and excised under general anaesthesia.  Histopathology was consistent with Hemangio-lymphangiomas.
Conclusion: Hemangio-lymphangiomas are not common in oral cavity but all suspicious cases should be properly investigated. Early detection and biopsy is necessary to determine the clinical behavior of the tumor and potential dentoalveolar complications.

Authors: Shambharkar Sonali , Mankar Preeti , Sakhare Manoj , Patil Manisha
Published: July 2022

Acquired defects in the maxilla lead to oro-antral communication with the nasopharyngeal complex. In recent times, post-Covid necrosis of maxilla due to mucormycosis leads to rapid invasion of surrounding tissues resulting in a maxillofacial defect. The surgically resected maxilla can have a devastating impact on the lifestyle, esthetics, speech and function of the patient. Obturators provide a hollow extension into the defect that seals the oro-antral defect and stops any communication between oral cavity and nasal complex. This case report describes the prosthodontic rehabilitation of a maxillary defect involving the left lateral hard palate and left posterior buccal mucosa with intact ridge over the defect area using a hollow bulb obturator. The lost wax technique used for fabrication of the obturator is an easy, cost-effective technique which is simple to execute from available resources. It provides hollowness to the prosthesis and reduces weight of the prosthesis thereby aiding in retention and stability of the denture.

Published: July 2022

Com o aumento da proliferação do mosquito Aedes aegypti, transmissor de doenças como a dengue, a febre amarela, a febre Chikungunya e o vírus da Zika, faz-se necessária a busca por métodos de combate ao mosquito. O uso intensivo de inseticidas comumente utilizados pelas organizações de vigilância sanitária tem provocado uma resistência e um problema no controle desses vetores. O presente projeto visa extrair o óleo essencial de botões florais do cravo-da-índia para sua utilização como agente larvicida, por se tratar de um controle sobre a fase larval do mosquito e já eliminá-la antes da fase adulta. Primeiramente, ocorreu a preparação dos botões e a extração do óleo essencial pelo processo de hidrodestilação. Foram realizadas análises para definir as propriedades físico-químicas do óleo, com isso foi possível classificar sua pureza e qualidade. Além disso, foi realizada a cromatografia gasosa, método utilizado para identificar os componentes do óleo essencial do cravo-da-índia, em que foram identificados dois constituintes. Após essas análises, seguiu-se com o teste de toxicidade que foi aplicado nas larvas do Aedes aegypti, utilizando concentrações mais altas do que às encontradas na literatura. A partir dos resultados coletados, foi estabelecida a concentração letal do óleo essencial em torno de 1,92 mg.mL-1, evidenciando a resistência criada por esses vetores ao longo dos anos. O óleo essencial de cravo-da-índia não apresentou nocividade frente ao meio ambiente e aos seres vivos, sendo muito viável o seu uso.

Authors: GONZAGA JÚNIOR J. E. , MAGALHÃES T. C.
Published: July 2022

Entende-se que o sucesso na construção de um empreendimento, executado na engenharia civil, está diretamente ligado à fidelidade de execução conforme seu cronograma, bem como a práticas que visam a austeridade de recursos financeiros do construtor. Um meio de se alcançar estes fins, é a compatibilização de projetos, antes da fase construtiva do empreendimento. Para demonstrar a veracidade deste conceito, são apresentados exemplos de duas obras, onde não houve a compatibilização na fase projetiva, levando à descobertas de incompatibilidade no canteiro de obras, o que gera ao empreendimento custos inesperados com consultorias, retrabalhos, descarte de insumos e atrasos em cronograma. Apresenta-se também, através do software Revit, a compatibilização entre os projetos arquitetônicos, estrutural e hidrossanitário na construção de um sobrado. A escolha desta ferramenta BIM se deu pelo aporte que a empresa Autodesck oferece, com a disponibilização do software de forma gratuita para estudantes, e a eficiência do software, que lhe gera um modelo 3D, simultaneamente à criação da planta baixa. Esta compatibilização, permitiu a visualização de possíveis interferências entre as disciplinas abordadas, evidenciando que é possível, no canteiro de obras, trabalhar com um projeto mais assertivo e confiável.

Published: July 2022

Com o crescimento dos casos de doenças transmitidas por vetores como o Aedes aegypti, o maior transmissor da dengue no Brasil, os óleos essenciais com propriedades repelentes são considerados uma opção promissora quando associados à nanotecnologia por sua baixa toxicidade e por serem biologicamente amigáveis. A encapsulação do óleo essencial em nanopartículas aumenta a estabilidade da substância promovendo uma liberação controlada no meio em que essas nanopartículas se encontram, aumentando sua durabilidade. Neste trabalho, nanocápsulas de óleos essenciais de cravo-da-índia e melaleuca com propriedades repelentes foram produzidas utilizando a metodologia de nanoprecipitação para o encapsulamento, sendo usado como material base para o revestimento o polímero poli(L-ácido lático), um polímero biodegradável. O processo de síntese das nanocápsulas está em desenvolvimento e, após sua otimização, pretende-se aplicá-las em tecidos de algodão de forma que eles adquiram a propriedade repelente.
A Methodology for Definition and Refinement of a LSTM Stock Predictor Architecture using iRace and NSGA-II
Authors: Costa Thiago F. , Wanner Elizabeth F. , Martins Flávio V. C. , Cruz André R. da
Published: July 2022

This paper presents a novel methodology aiming to define and refine a LSTM architecture applied to predict stock market prices. The methodology, dubbed STOCK-PRED: THE LSTM PROPHET OF THE STOCK MARKET, uses iRace and NSGA-II algorithms. The LSTM is built in two steps: (i) initially, iRace determines a robust set of hyperparameters using a compound objective function; afterwards, (ii) one of the best structures is used to define a tiny search space for the NSGA-II populations. In this step NSGA-II optimizes, simultaneously, the Mean Squared Error, in relation to price prediction, and the Accumulated Accuracy Rate for a time horizon of seven days, relative to growth price tendency. The methodology is tested considering stock market tickers from USA and Brazil. Even in a challenging scenario surrounded by possibly turbulent events, the Stock-Pred predicts the prices based on historical data and machine learning techniques. Since the optimization problem is noisy and the objective functions have a high computational cost, we consider a low budget in relation to the number of fitness evaluations. The analysis of the non-dominated solution indicates that the proposed methodology is promising, achieving a MAPE of 1.279%, 1.564% and 2.047% for BVSP, IBM and AAPL stocks respectively.

Authors: Rabeiy Ragab ElSayed , Almutairi Saud Jaza
Published: July 2022

The atmospheric stability and depth of the mixing layer are essential parameters in modelling the dispersion of pollutants and sandstorms in arid regions. In this study, a MATLAB model was used to determine the hourly atmospheric stability conditions and the depth of the mixing layer in the year 2019, especially during sandstorms events. The statistical analysis of hourly sandstorms was investigated over four decades (from 1980 to 2019) and its relationships with the weather conditions, especially wind speed and direction were figured in the study area. The average mixing layer during daytime hours in the summer season was 1800 ± 400 m, while during night hours, the average mixing height was 500 ± 200 m. The study concluded that the major wind direction during sandstorms was blowing to the south direction ± 22.5 degrees. It was noted that relative humidity increased while the average temperature decreased over the last decade during the sandstorm events due to the wide cultivation in this period. The cultivation of tall trees on the northwest side of the study area will decrease the severity of sandstorms in future. This study could be applied to arid regions that suffer sandstorms such as Arabian Peninsula.

Published: July 2022

Graphene oxide particles (GOp) were implanted on the surface of H62 copper alloy to prepare an H62/GOp-modified layer by friction stir surface processing (FSSP). The Raman spectrum and microstructure of the modified layer were tested and analyzed. The results showed that the H62/GOp-modified layer prepared under different parameters by FSSP had characteristic Raman spectrum peaks graphene oxide (GO), which indicates that the modified layer containing GO can be prepared by FSSP on the copper alloy surface. The surface grain structure of the H62/GOp-modified layer of each sample was refined, and their large-angle grain boundary ratios were above 85 % and higher than that of the base metal. In addition, the grain volume fraction in the dynamic recrystallization region of each sample was above 60 vol%, and the maximum was 73.9 vol%, which indicates the desirable microstructure consistency of the H62/GOp-modified layer prepared under different parameters by FSSP.

Published: July 2022

The object of this paper was to utilize the plum seed oil for the preparation of the topical formulation for skin care since it can improve elasticity and prevent accelerated skin aging. Soxhlet extraction of plum seed oil was performed using n-hep-tane. The spectrophotometric methods were applied to estimate the photoprotec-tive effect and antioxidant activity of the samples. The warm-warm emulsification process was used for the preparation of topical formulation based on plum seed oil. The antioxidant activity of the plum seed oil was estimated based on the half-maximal inhibitory concentration (9.39 mg/mL). After the incorporation of the oil in the topical formulation, the IC 50 value of 9.33 mg/mL was not significantly changed. The viscosities of the topical formulation and plum seed oil were 1.56×10 6 mPa·s (at the shear rate of 5 s-1) and 60.48 mPa·s (at the shear rate of 50 s-1), respectively. Rheological analysis showed that the plum seed oil and topical formulation were Newtonian and non-Newtonian pseudoplastic fluids, respectively. The formulation adsorbed the light in the UV-Vis range so that it can be used as a w/o emulsion photoprotective cream. The cream with adequate pH value was stable and micro-biologically safe for application to the skin. Due to the use of cheaper ingredients, the formulation is acceptable and suitable for manufacturing.

Published: July 2022

Higher education is a tool for social and economic development as well as global competitiveness. It is thus crucial for students to make informed decisions when enrolling at university and, ultimately, deciding what career to pursue. This article offers insights into the factors that influence students’ selection of a university and programme, focusing on students at a historically disadvantaged university in the Eastern Cape, South Africa. Data was gathered by means of qualitative focus groups and convenient sampling was employed to select the sample from a population of first-year students. The findings indicate that residential proximity to the university, the university’s reputation, programme image, entry requirements, affordability and funding influence university selection. With regard to programme selection, the factors considered include background dynamics, the subjects involved, failure to meet the requirements, family, peer or the influence of others, failure to be selected for first choice programmes, a lack of career guidance and funding availability. It was thus found that university selection was principally influenced by the student’s informed choice while programme selection was largely influenced by external factors.

Instructional Grouping Theory: Optimizing Classrooms and the Placement of Ranked Students
Authors: Wiens Peter D. , Zizzi Christine , Heatwole Chad
Published: July 2022

Two common approaches to grouping students include an approach where students are grouped based on their aptitude and a cross-sectional approach where equal groups are formed and comprised of students of varied aptitudes. Instructional Grouping Theory is the study of how selection strategies
impact the learning of group members. Using a non-biased, mathematically centric analysis, we found that a liked-skilled tiered grouping strategy is preferable to a cross-sectional grouping strategy when the goal is to facilitate the learning of all students. In addition, we found that a higher
teacher-to-student ratio provides further benefit when analyzing the potential for facilitated learning.

Published: July 2022

Considering the continued drive of human needs besides the constant improvement of technology, it is convenient to develop techniques that enhance the communication between computers and humans in the most intuitive ways as possible. The possibility to automatically recognize human gestures using artificial vision among other kind sensorsallows to explore a whole range of interaction applications to control and interact with environments. Nowadays, most of approaches for gesture recognition using sensors agree in the use of vision, myography and movement devices applied to robotic, medical and industrial applications. In the context of this work, we study the principles of using both vision andbody contact sensing applied to automatic classification of a human gesture set. For this, two different approaches are evaluated: Feed-forward Neural Networks and Hidden Markov Models. These models are studied and implemented for the recognition up to eight different human hand gestures commonly applied in collaborative robotics tasks. In our tests,we conclude the effectiveness of combining the information of two different sort of devices for human gesture recognition reaching accuracy rates up to 95.05% for a whole proposed Hand-gesture set.
Set Representation for Rule Generation Algorithms
Authors: Kharkongor Carynthia , Nath Bhabesh
Published: July 2022

The task of mining the association rule has become one of the most widely used discovery pattern methods in Knowledge Discovery in Databases (KDD). One such task is to represent the itemset in the memory. The representation of the itemset largely depend on the type of data structure that is used for storing them. Computing the process of mining the association rule im- pacts the memory and time requirement of the itemset. With the increase in the dimensionality of data and datasets, mining such large volume of datasets will be difficult since all these itemsets cannot be placed in the main memory. As representation of an itemset greatly affects the efficiency of the rule mining association, a compact and compress representation of an itemset is needed. In this paper, a set representation is introduced which is more memory and cost efficient. Bitmap representation takes one byte for an element but the set representation uses one bit. The set representation is being incorporated in Apriori Algorithm. Set representation is also being tested for different rule generation algorithms. The complexities of these different rule generation algorithms using set representation are being compared in terms of memory and time execution.
Poor Antifungal Coverage for Onychomycosis in a Cross-Sectional Analysis of Medicaid Formularies
Authors: Falotico Julianne M. , Lipner Shari R.
Published: July 2022

Background: Onychomycosis is the most common nail disease seen in clinical practice. Medication safety, severity of disease, co-morbidities, concomitant medications, patient age, and cost are all important considerations when treating onychomycosis. Since cost may affect treatment decisions, we sought to analyze Medicaid formulary coverage of onychomycosis antifungals.

Methods: Public state Medicaid formularies were searched for coverage of FDA approved onychomycosis medications and off-label oral fluconazole. Total drug cost for a single great toenail was calculated using National Average Drug Acquisition Cost. Pearson correlation coefficients were calculated to compare coverage and cost, mycological cure rate, and complete cure rate.

Results: Oral terbinafine and off-label fluconazole were widely covered for onychomycosis treatment. There was poor coverage of oral itraconazole and topical ciclopirox, and no coverage of topical efinaconazole and tavaborole without step-edits or prior authorization. There was a significant negative correlation between medication coverage and cost (r = −0.758, p= 0.040). There was no correlation between medication coverage and mycologic (r = 0.548, p = 0.339) and complete (r = 0.768, p = 0.130) cure rates.

Conclusions: There is poor Medicaid coverage of antifungals for the treatment of onychomycosis, with step-edits and prior authorization based on cost rather than treatment safety and efficacy.

Authors: Cunningham Karen L , Sauvola Chad W , Tavana Sara , Littleton J Troy
Published: July 2022

Voltage-gated Ca2+ channels (VGCCs) mediate Ca2+ influx to trigger neurotransmitter release at specialized presynaptic sites termed active zones (AZs). The abundance of VGCCs at AZs regulates neurotransmitter release probability (Pr), a key presynaptic determinant of synaptic strength. Although biosynthesis, delivery, and recycling cooperate to establish AZ VGCC abundance, experimentally isolating these distinct regulatory processes has been difficult. Here, we describe how the AZ levels of cacophony (Cac), the sole VGCC-mediating synaptic transmission in Drosophila, are determined. We also analyzed the relationship between Cac, the conserved VGCC regulatory subunit α2δ, and the core AZ scaffold protein Bruchpilot (BRP) in establishing a functional AZ. We find that Cac and BRP are independently regulated at growing AZs, as Cac is dispensable for AZ formation and structural maturation, and BRP abundance is not limiting for Cac accumulation. Additionally, AZs stop accumulating Cac after an initial growth phase, whereas BRP levels continue to increase given extended developmental time. AZ Cac is also buffered against moderate increases or decreases in biosynthesis, whereas BRP lacks this buffering. To probe mechanisms that determine AZ Cac abundance, intravital FRAP and Cac photoconversion were used to separately measure delivery and turnover at individual AZs over a multi-day period. Cac delivery occurs broadly across the AZ population, correlates with AZ size, and is rate-limited by α2δ. Although Cac does not undergo significant lateral transfer between neighboring AZs over the course of development, Cac removal from AZs does occur and is promoted by new Cac delivery, generating a cap on Cac accumulation at mature AZs. Together, these findings reveal how Cac biosynthesis, synaptic delivery, and recycling set the abundance of VGCCs at individual AZs throughout synapse development and maintenance.

Diversification following the end-Permian mass extinction marks the initiation of Mesozoic reptile dominance and of modern marine ecosystems, yet major clades are best known from the Middle Triassic suggesting delayed recovery, while Early Triassic localities produce poorly preserved specimens or have restricted diversity. Here we describe Pomolispondylus biani gen. et sp. nov. from the Early Triassic Nanzhang-Yuan’an Fauna of China assigned to Saurosphargiformes tax. nov., a clade known only from the Middle Triassic or later, which includes Saurosphargidae, and likely is the sister taxon to Sauropterygia. Pomolispondylus biani is allied to Saurosphargidae by the extended transverse processes of dorsal vertebrae and a low, table-like dorsal surface on the neural spine; however, it does not have the typical extensive osteoderms. Rather an unusual tuberous texture on the dorsal neural spine and rudimentary ossifications lateral to the gastralia are observed. Discovery of Pomolispondylus biani extends the known range of Saurosphargiformes and increases the taxic and ecological diversity of the Nanzhang-Yuan’an Fauna. Its small size fills a different ecological niche with respect to previously found species, but the overall food web remains notably different in structure to Middle Triassic and later ecosystems, suggesting this fauna represents a transitional stage during recovery rather than its endpoint.

Magnetic iron oxide nanoparticles were successfully synthesized by co-precipitation method. The magnetite and mixture of magnetite/ hematite iron oxide were obtained and characterized by X-ray diffraction, scanning electron microscopy, nitrogen adsorption/desorption isotherms and vibrating sample magnetometer. These nanoparticles exhibited good adsorbents performance for removal cadmium metal ion. The mixture of magnetite/ hematite particles showed small size of particle and removed cadmium ion rapidly. The rates of Cd removal were 90 and 95% with Fe3O4 and Fe3O4/α-Fe2O3 samples respectively and the pseudo first and second kinetic models were applied to describe adsorption. Langmuir and Freundlich models were used for describing adsorption isotherms.

Soybean, being an important pulse as well as oil seed needs special mention to overcome crisis in edible oil production in the country. It is also called as “Gold of soil”. An experiment was conducted at College of Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) during kharif (Soybean) and rabi (Amaranthus) season of the years 2019-20 and 2020-21. An agronomical investigation entitles effect of integrated nitrogen management in soybean and their residual effect on grain amaranthus under irrigated condition. The experiment soil was medium in organic carbon (0.40%), available phosphorus (36.20 kg/ha) and available potassium (209 kg/ha) with soil pH (8.15). There were ten integrated nutrient management treatments arranged in Randomized block design with four replications.  Integrated used of the organic and inorganic sources of plant nutrients on growth and yield attributes is very crucial for the assurance of food securities. Different observation on the crop parameters were carried out during course of investigation. Integrated nitrogen managements did not exert any significant response on plant population recorded at 20 DAS and at harvest and plant height at 30 DAS. All growth and yield parameters viz., plant height at 60 DAS, plant height at harvest, number of branches/plant, root nodules/plant, dry weight of root nodules, seed yield and straw yield were recorded significantly higher with the application of 50% RDN through vermicompost + 50% RDN through inorganic fertilizer (T3) sustainable agricultural productivity might be due to achieved through wise used of integrated nutrient management. At present soybean is one of the most important economical crops and having good nutritional response on healthy diet and information of same cropping sequence was not available for farming community so planned study on the application of organic sources of nutrients viz., vermicompost, FYM, bio-fertilizers (Rhizobium + PSB) under middle Gujarat conditions.

This study presents a novel approach to incorporating technology into an intelligent weather station. In recent years, the nation has experienced a decline in agricultural activities due to the change in climate causing lot of danger in the farm output; this enables the weather forecaster to actually prescribe disaster by employing the use of temperature, humidity and light sensors which senses the temperature and humidity in the atmosphere. A tipping bucket is used to measure the amount of rainfall with an ESP-32 microcontroller which displays results through a Liquid Crystal Display (LCD) and then send it to the registered number and at the same time is been sent to cloud for easy retrieval purpose using the internet which can be retrieved from any location. This system is designed primarily for use in the school meteorological stations, it is also applicable in various weather stations. The primary goal is to create a low-cost intelligent system for storing data obtained by measuring various physical parameters in the atmosphere, such as temperature, humidity, and rainfall. An ESP-32 is used as the technology for storing measured data; it is an advanced and efficient solution for connection to the Internet. The intelligent weather station system is built around the following steps: direct environmental sensing, data measurement and storage, and allowing users to access the results through the cloud. The system is built around a collection of embedded sensors, and a microcontroller serving as the system's core and server, and wireless internet communication protocol. The results were sent to the cloud, where they are displayed in a tabular and graphical format; these results can be retrieved from the cloud into an excel file.

Aim: To analyze the phytochemical and FTIR of six medicinal plants frequently used by the Ngas in Pankshin District of Plateau State, Nigeria in the traditional treatment of some ailments. 

Methods: The medicinal plants were extracted with water, ethanol and cyclohexane/hexane, screened for the presence and levels of phytochemicals by standard methods and the FTIR analyses were carried out on the ethanolic extracts.

Results: The study revealed that the aqueous extracts contained most of the phytochemicals analyzed. The quantitative analysis of five phytochemicals in four of the plants showed that the order of the levels of phytochemicals in plants were: alkaloids; F. phytophylla > C. tinctorium > F. abutilifolia > F. phytophylla, saponins; F. abutilifolia > F. phytophylla > F. abutilifolia > C. tinctorium, terpernoids; F. phytophylla > F. abutilifolia > C. tinctorium > F. abutilifolia, flavonoids; F. phytophylla > F. abutilifolia > C. tinctorium > F. abutilifolia and glycosides, F. abutilifolia > F. phytophylla > C. tinctorium > F. abutilifolia with saponins being the most abundant phytochemical in the study and flavonoids the least. F. phytophylla was richest in the phytochemicals while F. abutilifolia was the least. The presence of characteristic functional groups such as ─OH, C─O, –C=C and C─H indicated the presence of phenolic compounds, carboxylic acids, alcohols, carbohydrates, and proteins in the plants that could be responsible for various medicinal properties in the plants.

Conclusion: The results justified the local use of the plants in the treatment of illnesses like malaria fever, yellow fever, cough and healing of wounds among the Ngas people in Pankshin Local Government of Plateau State. These compounds can be harnessed for industrial and pharmaceutical utilization.
Thinking and Doing

Foucault (1986) reminds us that it is in the practices that power is actually exercised, not an ideas. This paper is an attempt to ask why, when feminism has had such an impact on the ideas of psychoanalysis and therapy, it has not deconstructed the practices. If power resides in the practices which aim to maintain the existing structures (and the existing dominant (male) symbolic) then analysis/therapy remains firmly patriarchal even as so many of its practitioners and clients are 'other'.
