The intense laser irradiation of a micro/nano size W sphere sample is considered in the present paper. Like numerical example, we choose a sphere with a radius of 1 µm. The present article’s point consists of approximating that the target’s temperature homogenization time is of the same order of magnitude as the first laser pulse duration. Our model is valid in the radius limits: 10 nm to 10 µm. We consider like heating source a laser beam with YAG/Nd:YAG/ Cr4+:YAG composite crystal. The nature of the interaction between a laser beam and small dimension tungsten (W) sample is of great importance for both theoretical and experimental perspectives. In principle, we have three stages: i) laser- W bulk interaction; ii) plasma formation, heating, and iii) adiabatic expansion. In the present paper, we will focus on the first two stages of laser pulse interval.
Recirculating Shower Filtration System: Utilizing Natural, CostEfficient, and Effective Materials to Consolidate the Purification of Water
Authors:   Independent Researcher, United States of America, Spiess Myles
Published: October 2021

The objective of this project was to make a recirculating water shower system that creates clean water using natural resources, without the requirement of additional electricity. Due to the use of natural materials, maintenance of the shower will be dramatically reduced. Our shower system filters the used water and integrates it back into the pipes of the shower, to be used again. The filter removes dirt, bacteria, debris, and biodegradable shampoo. It does so with different filtration methods in each part of the filter. As the water moves from top to bottom, the largest to the smallest impurities are removed from the water to ultimately leave it potable. The system purifies the water to below 5 Nephelometric Turbidity Units (NTU), the recommendation for drinking water by the World Health Organization. Cleaned water is collected and sent back to the shower head by a solar paneled water pump. Our economical shower system has the potential to reduce disease and allow for increased hygiene without wasting water.
Case Report of A Rare Idiosyncratic Hepatotoxicity Induced by Valproic Acid
Authors:   Sahel General Hospital, Gastroenterology Department, Lebanese University, Bouhairie Malek Michael , Nasreddine Sabrina ,   Sahel General Hospital, Gastroenterology Department, Lebanese University
Published: October 2021

Valproate induced hepatotoxicity is a well-known side effect, which frequently required periodic monitoring of serum drug level. Hepatotoxicity caused by valproate typically occurs at supratherapeutic drug levels. Once in a while, an idiosyncratic reaction is elicited, liver injury might occur despite normal serum valproate level mainly in chronic users. We hereby identify an unusual case of acute idiosyncratic valproate induced hepatotoxicity. We report a case of a 65 years old male with dyslipidemia and history of seizure, on valproic acid therapy, presented with altered mental status and drowsiness. The patient’s home medications include only zenil 10 mg daily and valproate which was started one month ago. At presentation, He was awake, oriented, but lethargic. Laboratory testing reveals hepatocellular injury with elevated transaminase levels, direct hyperbilirubinemia and coagulopathy. The ammonia level was normal and valproate level was within the therapeutic range. Abdomen computed tomography with IV contrast and MRCP results were irrelevant. Idiosyncratic valproate toxicity was diagnosed after exclusion of all other possible etiologies and after a rapid clinical and laboratory improvement once the drug was discontinued. Based on the patient’s clinical context the diagnosis of valproate induced hepatotoxicity was confirmed. This case emphasizes the importance of identifying, diagnosing, and managing valproate toxicity when no alternative clarification for their symptoms. We need further attempts and more researches to improve the detection of adverse hepatic reactions and to obtain reliable information about the discovery of new biomarkers or tools for early prediction of DILI, as well as to obtain accurate information on epidemiology, drug safety, and pathogenesis in order to improve management for better survival.

Authors: Thattarauthodiyil Usman , Shenoy Bhaskar
Published: October 2021

Objective: Aim of this study was to investigate the combined and comparative training outcomes of plyometrics and dynamic stretching of lower limb muscle groups on vertical jump performance in male and female collegiate volleyball players.

Materials and Methods: The study was carried out as two training sessions in a week, for eight weeks duration. The total number of participants was 90 male and 90 female collegiate volleyball players aged 18-22 years. All the participants were recreational players and they were playing one hour daily in the evening. They were randomly distributed into three male groups (Group 1, Group 2 & Group 3) and three female groups (Group 4, Group 5 & Group 6) with 30 participants in each group. All the participants underwent Sargent vertical jump performance test before starting the training session it was repeated in every two weeks of training program.

Results: Plyometrics and plyometrics with dynamic stretching led to significant improvements in vertical jump height (VJH), and this improvement was progressed after every two weeks of training. However, the control groups did not display any improvement. The effect of training was significantly higher in male and female groups who have performed plyometrics with lower limbs dynamic stretching as compared with the groups that performed only plyometric exercises (p<0.05). Compared to females, male participants had a better improvement of VJH in both training groups (p<0.05).

Conclusion: It can be concluded that two sessions of plyometric exercise training per week for eight weeks can improve the ability of VJH in male and female collegiate volleyball players. However, combined training of lower body plyometrics and lower limbs dynamic stretching had better results in terms of vertical jump performance.

O recebimento de receitas de royalties, oriunda de indenização financeira pela exploração de recursos naturais, impacta diretamente nas políticas de desenvolvimento socioeconômico dos municípios que as recebem. A região Oeste do Paraná passou por intensa transformação após a construção da Usina Itaipu Binacional, como forma de indenização pelo alagamento de parte do território de quinze municípios da região Oeste, a Usina já distribuiu até 2018 centenas de milhares de dólares aos municípios lindeiros. Nesse sentido, este artigo propõe verificar a partir da análise de índices socioeconômicos, como está a aplicação dos royalties nos municípios lindeiros do Oeste Paranaense no período de 2010 a 2018. Para atingir esse propósito, foram selecionadas 11 variáveis socioeconômicas para cada um dos 15 municípios lindeiros, utilizou-se de teste de regressão linear. Os resultados encontrados sugerem que os royalties não interferem no resultado dos indicadores socioeconômicos estudados, pois não há estatisticamente relação de significância entre as variáveis.
Effects of Storage Structure Type and Pesticide Type on The Physico-Chemical Properties of Cowpea (Vigna Unguiculatus) After Three Months’ Storage: The Case of Daffiama Bussie Issa District
Authors: Berchie Kwadwo Asante , Maaledoma Prosper
Published: October 2021

Cowpea is an important grain legume widely used as food in Ghana and the world at large. It is a significant protein source used by many people in several countries. However, its postharvest management, especially storage, can be problematic because it is easily attached by storage pest insects, particularly Callosobruchus maculatus. Cowpea storage is crucial as the product is protected against damage and deterioration. Also, it is preserved until such a time that market prices are reasonable before they are marketed, enhancing food security. Cowpea grains that are predisposed to insects often attack significantly reduce the quantity and quality, which renders the product unwholesome for human consumption. A survey will be conducted in Daffiama Bussie Issa District in the Upper West Region of Ghana to identify storage structures and storage protectants used by stakeholders to store cowpea. The cowpea variety to be used for the experiment is called ‘songotra’ and is considered the people’s choice. At the end of the storage period, the physical and chemical properties of the cowpea grains were assessed to confirm whether there is a significant effect on them. Test on the viability of seeds will be conducted. The findings will show which storage structure and protectants proved to be more effective by killing the cowpea weevil and unearth the treatment that will offer the highest and lowest protection. Pairwise Statistical Package for Social Scientists (SPSS) Version 9.0 was used to analyse the survey data. It is recommended that further research is conducted on the quantity of cowpea used for storage with an extended storage period.

The study aimed to explore the challenges and difficulties faced by Islamic financial inclusion through Islamic financial institutions (banks, microfinance, insurance) in women's economic empowerment in Yemen. This will lead to enhance women's place in economic development when finding appropriate solutions to these challenges. This study applied the qualitative approach by conducting in-depth interviews with the experts comprising eighteen respondents in Islamic financial institutions. The result of respondents showed that there are a number of challenges and difficulties associated with the environment that have implications for overall institutional action and directly or indirectly contribute to women's economic empowerment. Where customs and traditions constitute the biggest external challenge facing Islamic financial institutions, as well as women's financial illiteracy, and the unstable political conditions that Yemen is going through. In addition to internal topics associated with the policies of those institutions themselves, they are ultimately subject to the impact of external problems and challenges. Furthermore, the results of the study will help decision-makers to activate the role of compulsory in society and implement effective plans and strategies to empower women economically.
Consumer protection awareness in South Africa
Authors:   Durban University of Technology, Durban, South Africa, Mason Roger Bruce
Published: October 2021

This paper addresses the lack of knowledge about awareness of consumer protection in South Africa, especially amongst disadvantaged consumers. Literature shows that there is a high correlation between the level of economic development and the awareness of consumer rights. The more developed a country is, the more aware its people will be in terms of their consumer rights. The less developed a country is, the lower the level of consumer rights awareness consumers will have. Consumers, like any other citizens of a country, have a right to be protected by the law. Private and nongovernmental organisations and the consumer councils should to ensure that the interests and rights of consumers are well protected. The study involved a literature review and an exploratory empirical study into the effect of income and education on awareness of consumer protection by a sample of Durban consumers. A strong, positive relationship between consumer protection awareness and income and education was found. Recommendations for actions which should improve consumer protection awareness amongst low income, poorly educated consumers, are suggested in, this study, while, further research to develop a deeper understanding of the problem, and are also suggested.
USER EVALUATION OF INTERACTIVE THEMATIC 3D CITY MODELS – APPLICATION OF ASYNCHRONOUS REMOTE TESTING METHOD
Authors: Herman L.
Published: October 2021

Abstract. Asynchronous remote usability testing is a method based on a software platform used to automatically record test participants' activities when they interact with a given product in their natural environment, for example, at home. This method has been frequently used in previous decades in web design and mobile application development but has rarely been utilised in geovisualization. The importance of remote usability testing has rapidly increased in 2021 due to the COVID-19 pandemic. The 3DmoveR (3D Movement and Interaction Recorder) application was used for asynchronous remote testing presented in this paper. 3DmoveR is a research tool designed for user testing of interactive 3D visualizations in web browsers using open technologies such as PHP, JavaScript, and the Three.js library. This study focuses on an evaluation of interactive 3D city models presenting thematic information expressed by colour scale. An experiment was designed as a within-subject study consisting of two simple questionnaires, a training task and six experimental trials. Finding a building of a given category (depicted as building colour) within an interactive 3D city model was used as the experimental task. Speed and accuracy of user performances were recorded, as well as user strategy, subjective evaluations, and possible intervening variables. The results were recorded from 110 participants, where 76 of them were correct and analysed further. It can be concluded that the tested colour scale (based on the Energy Performance Certificate) was not entirely appropriate. We further analysed and discussed intervening variables that may affect remote usability testing of 3D visualizations.
COMPUTING WATERTIGHT VOLUMETRIC MODELS FROM BOUNDARY REPRESENTATIONS TO ENSURE CONSISTENT TOPOLOGICAL OPERATIONS
Authors: Jahn M. W. , Bradley P. E.
Published: October 2021

Abstract. To simulate environmental processes, noise, flooding in cities as well as the behaviour of buildings and infrastructure, ‘watertight’ volumetric models are a measuring prerequisite. They ensure topologically consistent 3D models and allow the definition of proper topological operations. However, in many existing city or other geo-information models, topologically unchecked boundary representations are used to store spatial entities. In order to obtain consistent topological models, including their ‘fillings’, in this paper, a triangulation combined with overlay and path-finding methods is presented by climbing up the dimension, beginning with the wireframe model. The algorithms developed for this task are presented, whereby using the philosophy of graph databases and the Property Graph Model. Examples to illustrate the algorithms are given, and experiments are performed on a data-set from Erfurt, Thuringia (Germany), providing complex geometries of buildings. The heavy influence of double precision arithmetic on the results, in particular the positional and angular precision, is discussed in the end.

Published: October 2021

Abstract. The objective of the envVisio method is to create generic tools and a flexible data backbone for the preparation, storage, linking and provision of complex and multi-thematic municipal geodata. Although geographic base data of the federal states in Germany are represented and processed in standardized and established data models and systems, there is also a large number of additional geodata such as environmental data and mobility data that are not managed in a uniform manner. Specifically, the envVisio method is about the further development of the model approaches for geospatial and environmental data provision. It is a new type of modeling method that has already been tested in individual state environmental authorities for interdisciplinary cooperation between the specialist departments. The development of technical solutions is intended to reduce the effort required to provide municipal geospatial data and to promote higher usability of public data. The aim of this article is to present the methods and the use cases to be implemented.
POINT-BASED MORPHOLOGICAL OPENING WITH INPUT DATA RETRIEVAL
Authors: Balado J. , van Oosterom P. , Díaz-Vilariño L. , Lorenzo H.
Published: October 2021

Abstract. Mathematical morphology is a technique recently applied directly for point cloud data. Its working principle is based on the removal and addition of points from an auxiliary point cloud that acts as a structuring element. However, in certain applications within a more complex process, these changes to the original data represent an unacceptable loss of information. The aim of this work is to provide a modification of the morphological opening to retain original points and attributes. The proposed amendment involved in the morphological opening: erosion followed by dilatation. In morphological erosion, the new eroded points are retained. In morphological dilation, the structuring element does not add its points directly, but uses the point positions to search through the previously eroded points and retrieve them for the dilated point cloud. The modification was tested on synthetic and real data, showing a correct performance at the morphological level, and preserving the precision of the original points and their attributes. Furthermore, the conservation is shown to be very relevant in two possible applications such as traffic sign segmentation and occluded edge detection.
A PARALLEL ALGORITHM FOR LOCAL POINT DENSITY INDEX COMPUTATION OF LARGE POINT CLOUDS
Authors: Vo A. V. , Lokugam Hewage C. N. , Le Khac N. A. , Bertolotto M. , Laefer D.
Published: October 2021

Abstract. Point density is an important property that dictates the usability of a point cloud data set. This paper introduces an efficient, scalable, parallel algorithm for computing the local point density index, a sophisticated point cloud density metric. Computing the local point density index is non-trivial, because this computation involves a neighbour search that is required for each, individual point in the potentially large, input point cloud. Most existing algorithms and software are incapable of computing point density at scale. Therefore, the algorithm introduced in this paper aims to address both the needed computational efficiency and scalability for considering this factor in large, modern point clouds such as those collected in national or regional scans. The proposed algorithm is composed of two stages. In stage 1, a point-level, parallel processing step is performed to partition an unstructured input point cloud into partially overlapping, buffered tiles. A buffer is provided around each tile so that the data partitioning does not introduce spatial discontinuity into the final results. In stage 2, the buffered tiles are distributed to different processors for computing the local point density index in parallel. That tile-level parallel processing step is performed using a conventional algorithm with an R-tree data structure. While straight-forward, the proposed algorithm is efficient and particularly suitable for processing large point clouds. Experiments conducted using a 1.4 billion point data set acquired over part of Dublin, Ireland demonstrated an efficiency factor of up to 14.8/16. More specifically, the computational time was reduced by 14.8 times when the number of processes (i.e. executors) increased by 16 times. Computing the local point density index for the 1.4 billion point data set took just over 5 minutes with 16 executors and 8 cores per executor. The reduction in computational time was nearly 70 times compared to the 6 hours required without parallelism.
TRANSFERABILITY ASSESSMENT OF OPEN-SOURCE DEEP LEARNING MODEL FOR BUILDING DETECTION ON SATELLITE DATA
Authors: Spasov A. , Petrova-Antonova D.
Published: October 2021

Abstract. A great number of studies for identification and localization of buildings based on remote sensing data has been conducted over the past few decades. The majority of the more recent models make use of neural networks, which show high performance in semantic segmentation for the purpose of building detection even in complex regions like the city landscape. However, they could require a substantial amount of labelled training data depending on the diversity of objects targeted, which could be expensive and time consuming to acquire. Transfer Learning is a technique that could be used to reduce the amount of data and resources needed by applying knowledge obtained solving one problem to another one. In addition, if open-source data and models are used, this process is much more affordable. In this paper, the Transfer Learning challenges and issues are explored by utilizing an open-sourced pre-trained deep learning model on satellite data for building detection.
ADAPTATION OF THE GLOBAL GEOID MODEL EGM2008 ON CAMPANIA REGION (ITALY) BASED ON GEODETIC NETWORK POINTS
Authors: Ferrara G. , Parente C.
Published: October 2021

Abstract. The knowledge of the geoid undulation, the height of the geoid relative to a given ellipsoid of reference, is fundamental to transform the ellipsoidal heights into orthometric heights. Global geoid undulation models developed from satellite gravity measurements appropriately integrated with other data, are free accessible in internet, but their accuracy may be inadequate for specific applications. Earth Gravitational Model 2008 (EGM2008) is one of those: usually available in grid form 2.5’ × 2.5’ (a geotif is developed by Agisoft with resolution 1’ × 1’), it defines the difference between the WGS84 ellipsoid height and the mean sea level, but in some areas the discrepancies between these geoid undulations and local correspondent measured values are on the order of various decimetres. For consequence, more accurate models are necessary. This article aims to determine a geoid undulation model suitable for Campania Region (Italy), starting from the global model EGM2008 (1’ × 1’) that is locally adjusted by using geodetic network points (GNPs) and GIS interpolation functions. Three different datasets are considered including respectively 20, 40 and 60 GNPs and three deterministic interpolators are applied in global way to generate geoid undulation grids: Inverse Distance Weight (IDW), Global Polynomial 1st order (GP1), Global Polynomial 2nd order (GP2). The resultant 9 models are tested on 20 additional GNPs. The experiments demonstrate that local geoid can be produced on a little area adapting global geoid by means of GNPs: the model obtained using GP2 and 60 GNPs, the most accurate one, fits the data with ±3.2 cm root mean square error (RMSE).
BEYOND HBIM: SERIOUS GAMES AND PROCEDURAL MODELLING FOR HERITAGE DISSEMINATION
Authors: Bagnolo V. , Argiolas R. , Cuccu S. , Paba N.
Published: October 2021

Abstract. In the study of built heritage, the potential offered by the BIM methodology finds effective application in the knowledge and dissemination process. Today, the HBIM methodology often develops from 3D scanning point clouds with the so-called Scan-to-BIM processes. The complexity that often characterizes the architectural elements of the historical heritage and the lack of information on construction details and geometries, constitute a critical factor that sometimes affects the effectiveness of the application of the BIM methodology. Procedural methods define an approach that can help us when it is necessary to use external modelling tools for the local modelling of complex elements. Algorithmic modelling potentially could significantly reduce the investment normally required in digital content modelling operations, also in terms of time consuming. Furthermore, in procedural modelling, the definition of the detail can be calibrated a priori according to the objectives of the workflow. The research addresses the difficult management of point clouds in workflows aimed at the realization of the so-called serious games, tools that have proved invaluable in educational and teaching processes, as well as in the dissemination and promotion of heritage. Involving a remarkable variety of digital instruments for representation, serious games define a research topic in which the different needs related to the representation of the complexity of the objects can be investigated. Aimed at defining an effective development process for serious games, the paper proposes an HBIM workflow for reconstruction of 3D environments of historic buildings starting from laser scanning surveying approach.
Integrating empirical models and satellite radar can improve landslide detection for emergency response

Abstract. Information on the spatial distribution of triggered landslides following an earthquake is invaluable to emergency responders. Manual mapping using optical satellite imagery, which is currently the most common method of generating this landslide information, is extremely time consuming and can be disrupted by cloud cover. Empirical models of landslide probability and landslide detection with satellite radar data are two alternative methods of generating information on triggered landslides that overcome these limitations. Here we assess the potential of a combined approach, in which we generate an empirical model of the landslides using data available immediately following the earthquake using the random forest technique and then progressively add landslide indicators derived from Sentinel-1 and ALOS-2 satellite radar data to this model in the order they were acquired following the earthquake. We use three large case study earthquakes and test two model types: first, a model that is trained on a small part of the study area and used to predict the remainder of the landslides and, second, a preliminary global model that is trained on the landslide data from two earthquakes and used to predict the third. We assess model performance using receiver operating characteristic analysis and r2, and we find that the addition of the radar data can considerably improve model performance and robustness within 2 weeks of the earthquake. In particular, we observed a large improvement in model performance when the first ALOS-2 image was added and recommend that these data or similar data from other L-band radar satellites be routinely incorporated in future empirical models.

No al futuro: veinte años después de Hedwig and the Angry Inch
Authors: Argyriou Konstantinos
Published: October 2021

La película Hedwig and the Angry Inch constituye un recurso relevante en el presente punto de inflexión, vinculado a la reactivación reaccionaria de argumentos esencialistas sobre la identidad de género. Volver a la historia de la representación de lo trans en términos no estigmatizadores es una tarea necesaria para debatir dicho giro. En el presente texto examino la figura de Hedwig en relación con la noción de sinthomosexualidad, presentada por Lee Edelman en su obra No Future. Asimismo uso como herramientas las fórmulas lacanianas de sexuación, el círculo encantado de Gayle Rubin, y lecturas anteriores y contrapuestas sobre la subjetividad y la corporalidad de Hedwig.

The study aimed to investigate and evaluate the oxidative stability of chicken thighs with skin stored in freezing conditions due to the effect of oregano essential oil for various times. The results were compared with a control group without the use of oregano essential oil. Samples of chicken thighs with skin were obtained from an experiment performed on a poultry farm in a deep litter breeding system. The results obtained from the application of oregano essential oil to chicken thighs with skin did not show a statistically significant difference (p >0.05) in the dry matter content, fat content and acid value compared to the control group, where coccidiostats were used in starter and growth feed mixtures. A statistically significant difference was found in the peroxide value by applying oregano essential oil to chicken thighs with skin compared to a control group containing coccidiostats in starter and growth feed mixtures when stored for 1 day at room temperature (p £0.01) and 12 months in freezing conditions at -18 °C (p £0.05) and a statistically non-significant difference (p >0.05) when thighs with skin were stored for 6 and 9 months in -18 °C freezing conditions. In the conclusion, it was stated that maintaining the oxidative stability of chicken meat means knowing the factors that affect it and prepare the conditions for its maintenance. Chicken meat is generally susceptible to oxidative damage because it is characterized by a high concentration of polyunsaturated fatty acids. With a sufficient amount of effective antioxidants, chicken meat could be a homoeostatic system, but it remains limited or free of oxidized compounds and reactive components. These questions are the subject of further research in the field of oxidative stability of chicken meat.

Published: October 2021

BACKGROUND: Grand multipara is the woman, who has given birth to five or more viable infants.Grand multiparity (GMP) in relation to obstetric performance is labeled as high risk: a pregnancy inwhich there is a factor maternal or fetal that will adversely affect the outcome of pregnancy.OBJECTIVE: To observe the frequency of different maternal and fetal complications associated withgrand multiparityMETHODOLOGY: A prospective, descriptive type of study conducted at Gynae ‘A’ Unit,Postgraduate Medical Institute, Lady Reading Hospital Peshawar from January 2008 to December 2008.All admitted antenatal patients who had five or more viable pregnancies were included in the study. Allpossible maternal and fetal complications were looked for and complete examinations of the neonateswere done in liaison with pediatrics unit.RESULTS: Amongst the hundred GMP women, 58% of the women had parity of 5 to 7, 37% had 8 to10 children while 5% had more than 10 viable pregnancies. Total 56% patients had normal vaginaldeliveries while 17 patients had C-section. Anemia, hypertension, diabetes, mal-presentation andantepartum hemorrhage were common prenatal complications.Prolonged and obstructed labour 8%, postpartum haemorrhage 8%, precipitate labour 5%, cord prolapse2%, ruptured uterus 2%, shoulder dystocia 1% and retained placenta 1%, were different complications.The major fetal complications seen were macrosomia, birth injuries, frequent neonatal ICU admissions,major congenital abnormalities and perinatal deaths. Total perinatal deaths were 07%, total maternalmortality was 03%, two women died due to severe haemorrhage while one died due to eclampsia.CONCLUSION: There is still high frequency of grand multiparity in our population which isassociated with frequent maternal and fetal complications. This leads to high maternal and fetalmortality.KEY WORDS: Grand Multiparity, Maternal complications, Fetal Complications, Maternal Mortality,Fetal Mortality.
