DEVELOPMENTS IN CAD/CAM TECHNOLOGY: POSSIBILITIES FOR DENTAL APPLICATION
Authors: Günes Büsra
Published: April 2023

Examining CAD/CAM technology and their use in dental treatments is the goal of this study. The computer-controlled technology known as computer-aided design and computer-aided production (CAD/CAM) allows for the design of the material to be generated in 3-dimensions on the computer monitor. Since the 1950s, it's primarily been employed in the aerospace and industrial sectors. The development of CAD/CAM technology in dentistry has made it possible to construct restorations out of high-performance materials that were previously difficult to shape. In the past 20 years, dental CAD/CAM systems have grown in popularity. Since 1984, several CAD/CAM systems have been created, including the Cerec, E4D, Procera, Everest, DCS President, Cercon, and Lava systems. In contrast to conventional impression methods, the advancement of such systems makes it possible to create the restoration in accordance with the features of the restoration and innate dental anatomy, generate the restoration quickly at the patient 's bedside, guarantee the peripheral and inner harmony of the restoration, boost its resistance properties, and offer an improved look and feel.

Authors: Onkar Patil Kalpesh , Vaidhya Shubhada
Published: April 2023

Third branchial cleft cysts are rare presentations of an abnormal persistence of the branchial apparatus during embryological development. Radiological investigations such as Computed tomography (CT scan) examination and Magnetic Resonant (MR) imaging studies help to diagnose in suspected cases. On CT scan these cysts appear as low attenuated homogeneous masses with well-circumscribed margins; on MR imaging, they demonstrate hyperintense relative to muscle on T2-weighted images. Definitive treatment is surgical excision. We present a case of a third branchial cleft cyst in 5 years old female child describing its diagnosis and treatment.

ROLE OF CT PULMONARY ANGIOGRAPHY IN EVALUATION OF PULMONARY THROMBOEMBOLISM IN COVID-19 POSITIVE PATIENTS
Authors: Jain Krati , Sakhi Pramod , Julka Kumud
Published: April 2023

Introduction- COVID-19 disease has been strongly associated with a pro thrombotic state and vascular endothelial
damage resulting into wide range of thromboembolic phenomena including deep venous thrombosis involving
extremeties, pulmonary artery thrombo-embolism and eventually pulmonary infarctions. Computed tomography
pulmonary angiography (CTPA) was used at our hospital for assessment of patients with risk of pulmonary embolism. It
plays a vital role in its establishing its diagnosis, defining its extent, stage and thereby guiding towards further
management. Materials and Methods- A Retrospective study was performed in Sri Aurobindo Medical College and
Post graduate Institute, Indore, Madhya Pradesh, India and was approved by the ethical committee. It was performed on
250 COVID-19 patients with clinically suspected pulmonary thromboembolism who underwent CTPA between the
months of December 2021 and May 2021. The scans were analysed by skilled radiologists, having good experience in
the field of CT reporting. Results- Our study demonstrated that approx. 14% of the patients had pulmonary
thromboembolism and these cases were observed in patients with moderate to severe lung involvement. ConclusionIn this study, we have thoroughly tried to assess the presence of pulmonary thromboembolism using CTPA and establish
its relationship with severity of lung involvement on HRCT

Published: April 2023

Background Splenic flexure mobilization has been considered the standard of practice in cases of low anterior
resection;however,it has been observed in southern Indian state population, splenic flexure mobilization is may not be
necessary for all patients of Dravidian ethnicity. Methods We evaluated the 26 patientswho underwent Laparoscopic
Reconstituting Subtotal cholecystectomy during July 2019 to Jan 2022. Preoperative parameters (Age, Gender,
diagnosis,location of tumor and Neoadjuvant therapy) and postoperative parameters (Duration of surgery,Hospital Stay,
complications, recurrence of malignancy) were compared.Aim of the study was to evaluate the outcome of Low anterior
rection without splenic flexure mobilization. Results There was no statistically significant difference in terms of
intraoperative,postoperative complications and oncological outcome when splenic flexure mobilization not done.The
operative time was similar in the both groups (P>0.05).The Postop complication rate was lower after robotic than after
laparoscopic (9% vs. 25.5%, P=0.07). Post operative complications observed in 6 patients (23%) including wound
infection, wound dehiscence, anastomotic leak and anastomotic stricture. 5 post op complications were seen in
laparoscopic cases;however,this was not statistically significant.On a median 24 month follow-up,the local recurrence
rates did not differ significantly between the 2 groups (5 for LAP vs. 1 for Robotic). Conclusion Resection of rectal
cancers by minimally invasive approach (Lap and Robotic) without the routine use of SFM do not increase postoperative
morbidity or oncologic risk in our subset of patients all of whom belong to the same Dravidian ethnicity. Compared to
robotic surgery, patients with laparoscopic surgery had more postoperative complications though the oncologic
clearance was comparatively similar.Hence,we suggest that Splenic flexure mobilization need not be done for patients
of Dravidian ethnicity as they possess small to medium stature, genetically. This needs to be validated by larger randomized studies.

Objetiva-se afirmar a importância das literaturas angolana e afro-brasileira na desconstrução de estereótipos racistas, bem como, promover reflexões sobre os processos de resistência cultural e construção identitária presentes nessas literaturas. Para tanto, desenvolve-se a análise dos contos: “Ana Davenga”, da escritora brasileira Conceição Evaristo, publicado em Olhos D’água (2016), e “Natasha”, do escritor angolano João Melo, publicado em Filhos da Pátria (2008). De caráter eminentemente bibliográfico, com uma proposição comparativista, a análise está ancorada no conceito de literatura-mundo, tendo em vista seu potencial crítico sobre as literaturas hegemônicas. Como principal resultado, foi possível notar uma ruptura dos estereótipos em relação às/os personagens negras/os, porque, nos contos estudados, elas/es exercem protagonismo, tornando-se sujeitos de suas histórias (KILOMBA, 2019).
Efficient Human Face Recognition in Real-Life Applications using the Discrete Wavelet Transformation (HFRDWT)
Authors: Eragi Saddam , BenSaid Fatma , Alimi Adel
Published: April 2023

Human Face receives major attention and acquires most of the efforts of the research and studies of Machine Learning in detection and recognition. In real-life applications, the problem of quick and rapid recognition of the Human Face is always challenging researchers to come out with powerful and reliable techniques. In this paper, we proposed a new human face recognition system using the Discrete Wavelet Transformation named HFRDWT. The proposed system showed that the use of Wavelet Transformation along with the Convolutional Neural Network to represent the features of an image had significantly reduced the face recognition time, which makes it useful in real-life areas, especially in public and crowded places. The Approximation coefficient of the Discrete Wavelet Transformation played the dominant role in our system by reducing the raw image resolution to a quarter while maintaining the high level of accuracy rate that the raw image had. Results on ORL, Japanese Female Facial Expression, extended Cohn-Kanade, Labeled Faces in the Wild datasets, and our new Sudanese Labeled Faces in the Wild dataset showed that our system obtained the least recognition timing (average of 24 milliseconds for training and 8 milliseconds for testing) and acceptable high recognition rate (average of 98%) compared to the other systems.
Optimal solving of a scheduling problem using quantum annealing metaheuristics on the D-Wave quantum solver

Published: April 2023

The main disadvantage of calculations on quantum computers is their non-determinism. For optimization problems, of course, it is possible to get surprisingly good results but without a guarantee of the actual optimality of the result, i.e, an assurance that there exists no better solution which could potentially be found by the quantum machine. In this paper, we propose an novel approach that provides such a guarantee of optimality. We generate a solution that is optimal in the strict mathematical sense, without probabilistic considerations. To accomplish this, we use the D-Wave quantum machine working as a sampler implementing quantum annealing -- an approach considered a hardware metaheuristic -- to obtain upper and lower bounds on the value of the objective function of the problem under consideration. Then, we use the Branch and Bound scheme controlled by quantum annealing. This allows us to obtain very quickly -- in constant time -- the boundaries of the considered subproblems. Our approach is a combination of calculations realized on a quantum machine controlled by procedures implemented on a classical computer, allowing us to generate optimal solutions to the NP-hard problems of task scheduling on a single machine with a total weighted tardiness criterion.  The proposed quantum algorithm shows a significant advantage over the classical CPU approach both in terms of calculation time and the number of generated solution tree nodes.
Periódicos brasileiros de turismo
Authors: Kohler Andre , Digiampietri Luciano Antonio
Published: April 2023

O trabalho avalia a estrutura intelectual de 16 periódicos brasileiros de turismo, por meio da citação e cocitação de 108.595 referências de 3.887 artigos (1990-2018). Busca-se traçar um panorama dessa estrutura intelectual, apresentar rankings de autores e documentos mais influentes, e “mapear” a estrutura intelectual (temas, subcampos etc.). Com o passar das décadas, a estrutura intelectual tem tornado-se, crescentemente, mais complexa e robusta. O contínuo crescimento da média e mediana de referências por artigo e aumento da importância dos artigos de periódico indicam, ceteris paribus, que as redes de acoplamento bibliográfico tendem a revelar, mais apuradamente, essa estrutura intelectual, com seus subcampos, temas e escolas de pensamento. Contudo, apesar desse aumento, há, ainda, poucos artigos de periódico dentre os documentos mais influentes e cocitados. É patente a grande influência e centralidade de livros didáticos e/ou introdutórios ao turismo, secundados por manuais de metodologia, os quais, em conjunto, indicam certo predomínio da pesquisa qualitativa. Nos agrupamentos de ciências sociais, percebe-se o domínio de livros, com a quase inexistência de artigos de periódico muito citados. Há marcada influência da sociologia, antropologia e geografia. Nos agrupamentos de estudos de negócios turísticos, predominam os trabalhos sobre destino turístico. Cumpre destacar que, nas redes de acoplamento bibliográfico (autores e documentos), dado que seu centro é ocupado por autores e livros de ampla utilização, os subcampos e principais temas da estrutura intelectual são observáveis, apenas, na semiperiferia e periferia dessas redes.

Tuberculosis is a major public health issue in Morocco. Moreover, since the upsurge of HIV, it has become a global health issue. The urogenital localization is rarely primitive and ranks fifth in Morocco after lung, lymph node, bone and digestive system localization. It is a severe pathology because the diagnosis is often late and the lesions often bilateral, threatening the patient with definitive renal failure and / or infertility. Imaging is essential for positive diagnosis, assessment and evaluation of the impact on the urinary system. Diagnostic confirmation is bacteriological or histological. The treatment combines anti-bacillary chemotherapy with sometimes reconstructive surgery of the kidneys and urinary tract.

A HYBRID MPPT ALGORITHM FOR SOLAR PV WITH BATTERY CONNECTED SYSTEM
Authors: R Harrini , V. Gopalakrishnan
Published: April 2023

Electricity generation using renewable energy resources rather than fossil fuels reduces gobar gas emissions from the power sector and prevents pollution. The best alternative to conventional energy sources is solar photovoltaic (PV) generation; however, it has some significant disadvantages, including high initial costs, poor photoconversion efficiency, and climatic dependencies. In order to overcome this, PPT techniques are used. The projected work provides a solar power system which tracks the maximum power point using Artificial Neural Network and Perturb and Observe algorithm. Additionally, it adds a new setup for the system that links the photovoltaic array as well as the battery to the system inverter’s DC-link through a single DC-DC converter that can act as both charge controller and Maximum Power Point Tracking (MPPT) device at the same time. When solar energy production exceeds demand, the excess energy is stored in batteries and provided during periods of very low irradiance. The DC voltage is converted into AC voltage using an inverter. The benefit of this technique is that it has greater tracking accuracy. For validation, the proposed model has been analyzed by using MATLAB/Simulink.
PSO based Solar PV system for SVPWM Controlled Induction Motor for Agricultural Applications
Authors: M Vivekanandhan , S Chitra
Published: April 2023

Nowadays, renewable energy sources play a major role in agricultural applications. The recommended Particle Swarm Optimization (PSO) algorithm with DC-DC converter supports in refining the output voltage. This is beneficial however since the partial shading condition of PSO technique has high output power with fewer searching steps of MPPT. The objective of this work is to propose a PSO based boost converter using Space Vector Pulse Width Modulation (SVPWM) method. PSO has been anticipated to track the Global Maximum Point (GMP) under the partial shading condition. The welfares of the SVPWM technique are fixed switching frequency and lower harmonic content. The centrifugal pump used in agricultural system is obsessed by SVPWM controlled three-phase induction motor. The extent of the motor as well as the photovoltaic array evaluations are certain as the water could be pumped out even at temperature fluctuations and irradiation levels. The efficacy of the proposed design is observed under the MATLAB/SIMULINK.
A COMPREHENSIVE REVIEW ON LEMONGRASS (CYMBOPOGON CITRATUS) OIL EXTRACTION AND ITS APPLICATIONS
Authors: Okpo, Samson Onoriode  , Edeh, Ifeanyichukwu
Published: April 2023

This article presents a comprehensive review of methods of extraction, properties, compositions and industrial application of lemongrass essential oil. Lemongrass (Cymbopogon citratus) essential oil has been used traditionally since ancient days in medicine as remedy to improve blood circulation, treat fever and malaria, promote digestion and as well used to increase immune system of the human body. Essential Oils of lemongrass are used in various industries. Some of the industries in which they are used extensively include Aromatherapy, Food and drink industry, Pharmaceuticals industry, Fragrance and Flavour industry, Agriculture and Livestock industry, Cosmetic and Soaps industry, House hold and Domestic. The quality of the essential oil from lemongrass strongly depends on the extraction method and operating conditions. Basically lemongrass essential oil can be obtained by various extraction methods, such as steam distillation, conventional solvent extraction, Soxhlet extraction, ultrasound-assisted extraction (UAE), hydrodistillation (HD), microwave-assisted hydrodistillation (MAHD), Simultaneous-distillation-extraction technique (SDE), Solvent-Free-Microwave-Extraction Technique (SFME) and supercritical fluid extraction (SFE) with CO2. The composition of essential oil of Cympobogon citratus contains α-pinene, β-pinene, delta-3-catrene, myrcene dipentene, β-phellandrene, β-cymene , methyl heptanene, citronellal, β-elemene, β-caryophyllene, citronellyl acetate, geranyl acetate , citral A , citral B, geraniol, elemol , and β-caryophyllene oxide, etc. In addition, lemongrass oil also contains essential minerals such as Fe, Zn, Mg, Na, K, Ca, Mn, P etc. The most important physicochemical properties of lemongrass oil includes specific gravity, Optical rotation, refractive index, percentage of citral, freezing point, moisture content, acid value, ester value, carbonyl value and phenol content . Nevertheless, the chemical composition of the essential oil of Lemongrass also varies with the geographical origin, cultivation practices, plant age, photoperiod, harvest period, cultivars, and extraction methods. However, for extraction of lemongrass oil, green technology such SFE, SDE, SFME and MAHD that are consumer and environmental friendly in industrial-scale essential oil production should be considered as a method to overcome the limitations of traditional distillation methods.

Restoration interventions aims at conserving heritage structures. Different situations may occur during restoration works comparing to standard construction works. These differences may cause special risks for workers and the structure itself. Risk analysis is widely used in restoration field in the world as a work plan routine. Definite division between restoration and standard works hasn’t been defined in Turkey. Aim of the study is revealing what kind of different risks restoration works carry, creating awareness and making recommendations for avoiding these risks. As method of this study, Fine Kinney Method was chosen. The risk factor was obtained by using probability, severity and frequency values. Listed masonry houses from Fatih district were chosen. The region is composed of civil architectural examples more densely comparing to whole Istanbul. The most important criteria is the fact that these houses are among the oldest masonry examples in Istanbul. They carry more risks with their current deterioration levels. The possible risks were listed and documented. The results were presented using Fine Kinney Method. Falling from height and partial collapse are found as main risks in restoration works. Risk levels and risk types of potential risks in restoration works show differences than the standard construction applications.

The application of Airborne Laser Scanning methods (ALS) in archaeology has opened a new chapter for prospective research in forest areas. Previously, these were under-explored due to the lack of effective methods for recording archaeological remains in forests. With LiDAR data, researchers can now use available analytical tools. Also, they have developed new tools by creating so-called image derivatives, which have expanded the possibilities of microrelief interpretation for the identification of archaeological objects. This paper presents the results of DTM analyses and field investigations that were carried out at the Osie archaeological site (Poland). The site was discovered thanks to DTM analyses, which made it possible to identify an extensive settlement complex from the Late Roman Period. The object of our research was to identify remains connected with modern forest management in the form of traces of ploughing. The aim was to see how spatial data analyses, by means of which we identify ploughing traces, correlate with the results of archaeological surveys.

One of the limitations of satellite techniques in archaeological investigations is the land cover. Heritage objects may be more or less visible depending on the land cover type. Low vegetation, such as grass or small shrubs, will usually allow us to determine the location of archaeological objects if the difference in height between the object and vegetation is not significant enough. Forest or high vegetation cover makes it more challenging to determine the location of potentially artificial structures. This project's study area covered 50×70 km of the lower reaches of the Vistula River, Poland. The authors searched for anthropogenic objects close to watercourses and analysed nine different (point, line and surface type) objects having a defensive, sepulchral or settlement function. Circular objects, ditches and earth embankments, burial mounds and strongholds of regular forms were found during this research. Based on nine different models processed with LiDAR-based DEMs, several characteristics and relationships of various types of objects were demonstrated. Moreover, optimal models for searching for archaeological objects in forest areas were defined.

The increasing demand of sengon wood (paraserianthes falcataria) as an industrial material that has high price in East Java province, especially in Jember district leads to increase deforestation on people forest as well as land use land cover change (LULCC) on agriculture areas. Study on Tanggul watershed which is the one of three biggest watersheds in Jember where LULCC into sengon plantations shown that erosion yields on sengon plantations was dominating by medium to very high erosion hazard level. The identification and conservation method used in this study is RUSLE and the conservation model used is sengon-coffee intercropping. The effeciveness criteria used is erosion yield on the field decreases until low level of erosion hazard level (below 60 tons/hectares/year). The 208 samples of sengon plantations were used to identify erosion yield and the results show that 75.9% of sengon plantations in Tanggul watershed have moderate to very high erosion hazard level with an average erosion yield at 257.49 tons/hectares/year. While simulation of scenario 1st, 2nd and 3 rd intercropping conservation model resulting erosion yield 158.2; 131.8; and 97.7 tons/hectares/year respectively. In this case, 3rd scenario is effective to reduce erosion yield to low level of erosion hazard level by 65% of total plantations. However, other conservation model still needed to be added in the sengon plantation to reduce erosion in low hazard level.

La universidad, los archivos y la memoria: experiencias en la Universidad Nacional de Quilmes
Authors: Santin Silvina Ana
Published: April 2023

Este escrito es el resultado de una serie de entrevistas realizadas a personalidades clave en la práctica archivística. Tras el análisis y reflexión que realizamos inspiradas en ellas, organizamos nuestra exposición sobre la forma en que diversos actores se comprometen día a día con la labor de documentación, reflexionamos sobre el sentido de la acción de archivo en las universidades y observamos los aspectos que la dificultan o facilitan, en vistas a analizar la posibilidad de generar una cultura de custodia de la memoria. Algunas preguntas que guiarán nuestra reflexión son: por qué resulta pertinente y relevante generar una cultura de la memoria en las universidades, de qué manera conduce a eso procurar conformar archivos universitarios, de qué forma preserva la universidad su memoria, con qué tipo de reservorios o repositorios, de qué manera colabora la gestión documental con la función académica e investigativa, qué tipos de trabas, obstáculos o dificultades deben sortearse para generar un patrimonio documental, y finalmente cuáles son las ventajas de hacerlo.

History of the Beginning of Buddhism in Sikkim
Authors: - Sunita Kharel
Published: April 2023

The beginning of Buddhist faith in Sikkim may be traced back to the middle of the 17th century when Phuntsog Namgyal was consecrated as the ruler of the land as Dharma raja with both temporal and spiritual powers. It is believed that in the middle of the 8th century, Padma Sambhava also known as Guru Rimpoche travelled to Tibet and Sikkim and blessed the land. The land is recognized as sacred ever since and also blessed by the great Buddhist saints and the lamas. Immediately after becoming the ruler of the land, the king set himself to the task of administrative and religious reforms.

Authors: - Surbhi Abhange , - Nisha Shinde , - Bhagyashree Sonawadekar
Published: April 2023

Background
Bowling is an overhead activity which causes a ballistic motion of the body. Scapular Dyskinesia is believed to be more common in cricket bowlers due to their heavy reliance on unilateral upper extremity function. The scapula serves many roles in order for proper shoulder function to occur. Due repetitive overhead activity of cricket bowlers, there are more chances of Scapular Dyskinesia to occur in Cricket Bowlers hence the study was carried out.
Objective
The purpose of this study was to find out prevalence of Scapular Dyskinesia in Cricket Bowlers. One of the objective of this study was to find out wheather the Scapular Dyskinesia is associated with pain or not while doing throwing movement.
Methods
30 male Cricket Bowlers of age group 18 to 35 years with minimum experience of 2 years in bowling were selected to inclusion and exclusion criteria. Consent had taken from Cricket Bowlers prior to study. Scapular Dyskinesia had been evaluated by Scapular Dyskinesia test.
Data was collected and was statistically analyzed.
Result
Out of 30 participants, 3 participants were tested positive for Scapular Dyskinesia.
Conclusion
The study concludes that the Prevalence of scapular dyskinesis was found in 10% of total participants.

Authors: - Kodwo Owusu , - Alexander Kweku Eshun , - Khalid Attah-Osei
Published: April 2023

Basketball coaches in the Cape Coast Metropolis have long been struggling with their basketball players' shooting accuracy especially those in the senior high schools. This is because it does not compare well to the standards of players in the same age group because players in the metropolis have poor shooting rates. There is strong evidence from literature indicating that athletes with high levels of fitness, particularly performance related fitness, also known as skill-related fitness, do better than their peers in the various games and sport. The purpose of this study therefore was to find out the effect that performance related fitness training will have on shooting accuracy of senior high school basketball players in the Cape Coast Metropolis'. The researchers randomly sampled and assigned twenty (20) male and twenty (20) female basketball players to the experimental and control groups by same means. The males had a mean age of 17.15yrs, weight of 73.20kg, and height of 1.79m, and the females had a mean age of 17.15yrs, weight of 68.65kg, and height of 1.64m. The control group went through mini-clinic that concentrated on passing and dribbling as a placebo, while the experimental group participated in a series of drills over a twelve-week period intended to improve their performance related fitness. Standardized tests were employed for the performance related fitness tests and the researchers modified the tests used by Uzicanin et al. for shooting accuracy. Data was analyzed using the t test.
There was a statistically significant difference in the shooting accuracy of the male experimental group between Pretest and Week six t(9) = 0.568, P = < 0.001. Pretest mean (M) = 3.67, SD = 1.19; Week six mean (M) = 5.06, SD = 1.13). There was also a statistically significant difference in the shooting accuracy between Pretest and Week nine t(9) = 0.685, P = < 0.001 Pretest mean (M) = 3.67, SD = 1.19; Week nine mean (M) = 6.67, SD = 0.77). Statistical significant difference was also observed between Pretest and Week twelve t(9) = -13.062, P = < 0.001, Pretest mean (M) = 3.67, SD = 1.13; Week twelve mean (M) = 7.06, SD = 0.68. Nonetheless, There was no statistically significantly between Pretest and Week three (t(9) = -0.844, P = 0.388; Pretest mean (M) = 3.67, SD = 1.19; Week three mean (M) = 3.96, SD = 1.37). A similar finding was found for the female as well. Between the experimental group of male and female the researchers found no statistically significant differences them after the twelve weeks of intervention. Basketball coaches should as part of their plan design a program that intends to improve on their players' performance related fitness, particularly during the conditioning phase of preparation for tournaments. They should also conduct regular assessment of the players throughout the season to identify when fitness especially performance related fitness begin to go down to find ways of improving on it.
