Published: April 2022

Any theft of the real card (Credit) or the arrangement of the card data, or potentially cardholder data, is the start of a Visa fraud. A vendor store agent duplicating deal receipts is one example of a tradeoff that can occur in a variety of ways. Because of the wide geographic reach that security lapses on databases holding MasterCard data might have, security lapses on databases including MasterCard data can be particularly large and costly. In one example in 2005, 40 million Visa customer accounts were stolen as a result of a single trade off of a massive database including charge card information. This had global consequences since fresh cards had to be issued to a huge number of cardholders all over the world. There are mays of credit card fraud, in this paper I concentrate some of them. Now a days we are facing a risk in payment of card, everyday payment for the exchange has been increasing as a result of the rising technique of instalment type and the introduction of new channels for the exchange.

Published: April 2022

Background: The use of telemedicine for postoperative visits is increasing, especially in rural areas. Few studies have investigated its use for arthroscopic shoulder patients. This study aims to evaluate patient satisfaction with telemedicine for postoperative clinic visits following arthroscopic shoulder procedures in a rural setting.Methods: Patients were prospectively enrolled using the following exclusion criteria: <18 years, open procedures, and non-compliance follow-up at 6 weeks postoperatively. All patients completed a 13-question satisfaction survey, while telemedicine patients completed an additional, separate seven-question survey. Patients who switched groups completed a four-question prompt to determine the reasons for switching. Differences between groups were evaluated by either Student t-test or Mann-Whitney U-test.Results: The study enrolled 32 patients, with five patients following up by telemedicine and 27 in person. Age and distance from clinic were similar between patients who were assigned to the telemedicine group, completed the telemedicine visit, and opted for in-person visits (all p>0.05). Patient satisfaction did not vary significantly based on care by the surgeon, concerns being addressed, thoroughness of visit, overall clinical assessment at a prior visit, and improvements in pain and physical function (all p>0.05). Among patients who opted out of telemedicine visits, the most common reason was a preference to meet in-person but these patients agreed that telemedicine visits are a good idea.Conclusions: Regardless of type of follow-up, individuals reported similar levels of satisfaction with treatment during the visit and improvements in pain and physical function.

Authors: OKAL BENARD ODOYO , YAKUB A. , OKELLO J. , KODAK B. O.
Published: April 2022

The practice of instilling morals to individuals has existed in both familial and societal upbringing. These morals are always transmitted from the older people to the younger generation with an intention of initiating both boys and girls to proper manhood and womanhood based on the familial and societal dictates. Transmission of these morals is normally through religious and literary texts, and also continuous conversations amongst the members of the family and the society. These conversations generally tend to exhibit an aspect of speech act theory called illocutionary speech act that signals acts such as directing, advising, requesting and persuading the recipient to embrace the teachings. Though there are many genres of literature, poems have proved to be more effective in passing these morals in both the ancient and modern societies. Therefore, this article analyzed the themes and illocutionary speech act in some selected advisory Biblical and literary texts with poetic style. The study realized various themes such as lavish life and alcoholism, human rights, characteristics of ideal wife, philanthropy, respect, courtesy, faithfulness, avoidance of anger, discipline, religiosity, education, tolerance, integrity, marriage life, cleanliness and love. The study realized common illocutionary speech acts such as expressives, directives, verdictives, representatives and commissives.

Authors: TOPAÇ Mehmet Murat , OLGUNER Can , BAHAR Egemen
Published: April 2022

Design and experimental validation stages of an independent front suspension (IFS) that is designed for truck tractors of articulated commercial vehicles are summarised. Firstly, the suspension geometry, which satisfies the required conditions of minimum deviation of camber angle and track width during wheel travel, is obtained within the given design volume by using Multibody Systems (MBS) and Design of Experiments (DOE) approaches. Subsequently, the kinetic analysis is carried out for the suspension system and the critical design loads that may act on the structural elements are determined. Taking these loads into account, the mechanical design of the suspension system elements is performed. The Finite Element Analysis (FEA) is applied to the complete suspension system for the chosen critical load conditions. Stress concentrated regions on the crucial system elements are determined and improvements are indicated, which result in the reduction of stress concentrations. In the last part of the study, prototyping and fatigue tests are carried out. Throughout bench tests, in which real service conditions are simulated, no failure of any sort is encountered. The final suspension system (pair) is 31% lighter than an equivalent rigid front axle in terms of load capacity.

Authors: Ishigaki Tomonori , Ishimori Hiroyuki , Kitamura Hiroki , Yamada Masato
Published: April 2022

The long-term safety management of hazardous substances is essential to the development of an environmentally sound resource circulation society. To achieve this, engineering measures to attenuate environmental risks in the isolation and sequestration of hazardous heavy metals are reviewed. From the standpoint of the isolation and sequestration of heavy metals from resource circulation, we assess the challenges in implementing immobilization technologies, constructing updated isolation structures, and controlling environmental conditions. It is also focused intensively on the (bio) chemical transformation behavior of heavy metals and its effect on the migration of the transformed materials in the environment. The contributions of solubilized and gasified metal components to emission into the environment are considered. The obtained results underscore the necessity of multiple barriers to retard and attenuate the migration of hazardous heavy metals. Innovative schemes for the isolation and sequestration of heavy metals will lead to higher levels of safety and environmentally sound resource circulation.
For Better or for Worse: The Impact of Workplace Automation on Work Characteristics and Employee Well-Being
Authors: C.W. Peeters Maria , Plomp Judith
Published: April 2022

This article examines the consequences of implementing an automation technology (i.e., Robotic Process Automation; RPA) for work characteristics and employee well-being. Based on the job demands-resources framework we examined to what extent the utilization of RPA was related to job resources (i.e., autonomy and task variety) and a job demand (i.e., information processing), and to what extent these work characteristics were related to work engagement and exhaustion. Data were collected among 420 employees working for a Dutch ministry where RPA was recently introduced. Structural equation modeling revealed that RPA use was negatively related to both autonomy and task variety, which formed a threat to employee work engagement. Contrary to our expectations, RPA use was unrelated to information processing and subsequent exhaustion. These findings put emphasis on the importance of designing new technologies with sufficient job resources to create and maintain a healthy and motivated workforce during and after implementing workplace automation.
Effects of Electrolyte on Redox Potentials
Authors: R. Miller John , J. Bird Matthew
Published: April 2022

Redox potentials, especially as measured by cyclic voltammetry and related electrochemical techniques, are the basis for understanding energetics of photochemical solar energy storage, organic photovoltaics, light-emitting diodes, and even photosynthesis. These very popular techniques are dominant although none of the energy systems just mentioned contain large concentrations, typically 100 mM, of supporting electrolyte needed for electrochemical techniques to work. At the same time, the added electrolytes often have large, but unknown effects on the energetics studied. Despite substantial efforts using microelectrodes, it has not been possible to utilize electrochemical techniques to measure redox potentials in the absence of electrolytes. This chapter will be an account of new techniques applying the method of pulse radiolysis to partly answer the question: what is the effect of electrolytes on redox potentials?
Bacterial Biofilm and the Medical Impact
Authors: Jaffar Norzawani
Published: April 2022

Most pathogenic bacteria species form biofilm as their protective mode of growth, which helps them survive from the bactericidal effect of the antimicrobials or the killing activity of the host immune cells. The bacteria cells’ survivability via biofilm formation creates challenges in the medical field in terms of the device and also disease-related to biofilm. The impact of the bacterial biofilm issue is worsening over time, and the association to the high tolerance to the antimicrobial agents leads to increased morbidity and mortality worldwide. This review will highlight the main characteristics of the biofilm, the issue of biofilm in clinical practice, which also covered the pertinence of the biofilm in clinical practice, device-related biofilm disease, oral disease, and the significant bacterial species involved in the biofilm-related infections. Knowledge about the vital role of bacterial biofilm in related disorders will give new insight into the best approaches and alternative treatments for biofilm-related disease.
Perspective Chapter: Moderate Aortic Stenosis and Heart Failure with Reduced Ejection Fraction; Early Replacement or Conservative Treatment?
Authors: Karakanas Asterios , Michailidis Theodoros , Gogos Christos , Patoulias Dimitrios , Nazou Georgia , Schizas Nikolaos
Published: April 2022

Aortic stenosis (AS) is the most common valve lesion among the continuously aging population with serious effect on the left ventricular ejection fraction (LVEF). If left untreated, it is associated with serious complications such as heart failure (HF), pulmonary hypertension, thromboembolic events, and even sudden death. Early diagnosis and treatment is of outmost importance to avoid the above complications but also to maintain the patient’s normal heart function. Echocardiography is the key examination that assesses the severity of the stenosis, valve calcification, left ventricular (LV) function, and wall thickness. Also new imaging methods such as cardiac computed tomography (CT) and cardiac magnetic resonance imaging (MRI) help in assessing the severity of aortic valve stenosis when echocardiography has limitations. Based on the categorization of the severity of the stenosis, its treatment is determined. Although things are clear in cases of asymptomatic disease and severe stenosis, this is not the case in moderate disease. Experts and clinical trials do not define clearly which cases can be treated conservatively and which need surgical or transcatheter intervention. The purpose of this article is to gather all the latest data on the treatment of moderate aortic stenosis, especially in patients with heart failure and low ejection fraction.

Global food security is under-challenged due to over increasing human population, limited cropland, and risk of climate change. Therefore, an appropriate agricultural policy framework needs to be developed for food security that should be sustainable economically and ecologically. Nitrogen (N) is a crucial element that controls the growth productivity of crop plants. N accounts for around 78 volume per cent of the atmosphere but all crop plants cannot use it directly. Agricultural land is mostly dominated by cereals (e.g. rice, wheat, maize) which have specifically high N demand as compared to food legumes. Soybean exemplifies the most significant and cultivated food legume, presently cultivated worldwide under varying climatic conditions. It plays a significant role in global food security as well as agricultural sustainability due to a high seed protein and oil concentration, and low reliance on N fertilization. Soybean enriches soil health by fixing atmospheric N through biological nitrogen fixation (BNF), the most productive and economical system for N fixation and crop production, associated with more intensive production systems. However, the efficiency of BNF depends on several factors. This study is focused to develop more reliable guidelines for managing BNF by using the potential of natural agro-ecosystems.
Development of a Quality Gate Reference Model for FDM Processes
Authors: Randermann Marcel , Hinrichs Timo , Jochem Roland
Published: April 2022

Additive manufacturing (AM) enables industries to accomplish mass customization by creating complex products in small batches. For this purpose, fused deposition modeling (FDM) is widely used in 3D printing where the material is applied layer-by-layer from a digital model to form a three-dimensional object. There still exist problems in FDM processes regarding the failure rate of printed parts. Failures vary from deformed geometry, clogged nozzles, and dimensional inaccuracies to small parts not being printed that may be attributed to various process steps (e.g., poor quality CAD models, converting issues, overheating, poor quality filament, etc.). The majority of these defects are preventable and are caused by imprudent try-and-error print processes and troubleshooting quality control. The aim of this chapter is to propose a quality gate reference process with defined requirement criteria to prevent the occurrence of defects. The framework shall be applied in quality control and in-situ process monitoring to enhance overall manufacturing quality.

Coastal areas are highly productive in terms of natural resources and important for their strategic location. This leads to the development of industry, ports, and townships/cities in coastal areas. Therefore, many assets/ infrastructures are developed in coastal areas which are managed by respective administrations. Proper management of these assets requires a geographic information system (GIS) that can integrate and disseminate geospatial data along with ground photographs. The advancement of open-source geospatial technology enables the development of feature-rich yet cost-effective GIS applications. In the present chapter, one such web GIS framework is discussed for mapping and management of coastal assets using open-source geospatial technology.
Trend of Resistance Spot Welding Technology of Al-Si Coated Hot-Stamped Boron Steel for Automobile Body
Authors: Kim Wonho , Ji Changwook
Published: April 2022

As environmental regulations have been tightened around the world, domestic and foreign automobile industries are increasing the proportion of hydrogen and electric automotive components using lightweight materials to reduce exhaust gas emissions and improve fuel efficiency. In particular, hot-stamped boron steel is being used as an alternative material for frame weight reduction due to thickness reduction, excellent workability, and good elongation. However, surface coating is essential to prevent surface decarburization phenomena and oxidation scale formation between hot stamping processes of boron steel. The coating layer causes many problems in the weldability such as a narrow weldable current range and deterioration of mechanical properties during resistance welding. Therefore, in this study, we introduce research performed to improve the weldability of Al-Si coated hot-stamped boron steel in terms of the material and process.

During welding of structure, non-uniform thermal distribution is occurred by local heating and conduction in copula. This process causes non-uniform thermal deformation and that occurs thermal stress. Especially, pipe is used in shipbuilding and laying pipe is essential. As well pipe material is applied with STS 316L (Stainless Steel) and STS Duplex(Stainless Steel Duplex) in LNG carrier ship. So welding property of that material is studied in order to predict welding deformation and thermal stress. First of all each material is made a experiment to know thermal distribution and shrinkage deformation. Through this experiment, it was possible to obtain differences in welding shrinkage due to the mechanical and thermal properties of the two materials. As a result, basic data on welding shrinkage for each material were obtained, and it will be used to develop a prediction equation through additional research in the future.

: Bronchobiliary fistula (BBF) is a rare, but serious disease; therefore, early diagnosis and treatment are essential. Recently, the use of a minimally invasive procedure that directly embolizes the BBF has emerged as a useful therapeutic alternative for conventional treatments, such as drainage tube insertion or fistulectomy. Here, we report a case of a 56-year-old man, who was successfully treated with percutaneous transhepatic embolization using n-butyl cyanoacrylate and microcoils and was symptom-free for two years after the procedure. Percutaneous transhepatic embolization can be a successful alternative option for the treatment of BBF. Improved outcomes are expected in long-term follow-ups, especially when n-butyl cyanoacrylate and microcoils are used together.

Background: Cytokines are glycoprotein compounds with an important role in inducing and regulating inflammation. Objectives: The present study aimed to measure the effect of Aloe vera alcoholic extracts on inflammatory cytokines in rats fed with a high-fat diet. Methods: Forty adult male Wistar rats were purchased and randomly categorized into five groups, including two control groups (control and control fed a high-fat diet (HFD) and three experimental groups (high-fat diet + 150 mg/kg Aloe vera, high fat diet + 300 mg/kg Aloe vera, and high-fat diet + 600 mg/kg Aloe vera). The rats in the experimental groups received high-fat emulsion and three doses of Aloe vera for 60 days in the form of gavage. Following blood sampling, serum concentrations of tumor necrosis factor-alpha (TNF-α), transforming growth factor-beta (TGF-β), interleukin 6 (IL-6), and interferon-γ (INF-γ) were measured. Statistical analysis was administered using SPSS-20 software by ANOVA test. Mean comparisons were conducted via Duncan’s multiple range test at the 0.05 level of significance. Results: The findings showed that a high-fat diet (HFD) could increase the concentrations of inflammatory factors TNF-α and TGF-β (P < 0.05). Moreover, an increase in the concentration of inflammatory factor IL-6 was observed at P < 0.01. No significant effects were observed in the mean concentration of INF-γ in the study groups. The use of Aloe vera gel extract considerably reduced inflammatory factors TNF-α, TGF-β, and IL-6 in the Aloe vera extract-receiving groups. Conclusions: In general, the results of the present study revealed that Aloe vera alcoholic extract reduced inflammatory factors in the rats fed with a high-fat diet.

Background: Globally, 1.5 to 3 million people are exposed to snakebites each year. More than 100,000 of these cases, primarily in the tropics, result in death. This study includes an analysis of a university hospital's three-year experiences of distal extremity snakebites. Methods: This study includes 68 patients presented at the Emergency Department (ED) of Gaziantep University Hospital with snakebites on distal extremities (hands, fingers, and feet) between 01/03/2014 and 01/03/2017. Results: A total of 68 patients had wet snakebites on their distal extremities. Forty-seven patients (69%) were male, 21 (30.9%) were female, and the mean age was 43.03 ± 18.13 years. Snakebites most commonly occurred in September (26.5%, n = 18). Twenty-five (36.76%) patients had systemic symptoms (grades 2, 3, and 4). Also, 98.5% (n = 67) of patients received only antivenom therapy. Compartment syndrome was observed in one patient (1.5%), and this patient was treated with antivenom therapy and plasmapheresis. The most common local finding was pain (88.2%, n = 60). Also, 2.94 ± 2.5 vials of antivenom (range 0 - 10) were used per person on average, whereas the mean duration of hospitalization was 2.51 ± 1.5 (range 1 - 8) days. Conclusions: This study focused on hands, fingers, and feet because these parts can be protected (ie, preventing bites) by wearing shoes and protective gloves. Also, there was no mortality due to extremity snakebites. The most common long-term complications were paresthesia and movement limitation. It is recommended that high-risk populations (like agricultural laborers, nature travelers, and documentary teams) be taught appropriate first aid practices after snake bites.
