Published: September 2020

Data is very important nowadays for almost all organizations for their existence as well as for their growth. The Internet has become the major source of data for individuals and almost all organizations. Authentic Websites are a major source of reliable data for many individuals and organizations. Extracting Data from websites is commonly referred as Web Scrapping, which refers to both manual and automated process. Extracting large amount of meaning full data from the websites manually is very difficult, tedious and redundant task. Automated Scrapping is done by writing specific programs to extract the required data from the websites. These programs are usually called as web scrappers. Web scrappers are written using many programming languages like Python, Node.js, Ruby, C++, PHP etc. Each language has its own unique features and built in libraries for performing data extraction. There are many web scrapping tools like Beautiful Soup, Octoparse, Parsehub etc. In this article we are going to analyses few recent Web Scrappers tools used in scrapping the Web.

Published: September 2020

Objective: The primary aim of this study was to summarize the current state-of-science for principles and practices of intervention in acquired pediatric aphasia (APA). A secondary aim was to identify gaps in research regarding interventional frameworks, and to identify key areas of future inquiry to optimize language outcomes. Conclusions: Although epidemiologic data indicate rising incidence in APA, limited research on recovery and intervention exists. Results suggest that language intervention supports aphasia recovery; however, available data lack adequate description of methodologies to make crosscomparisons and dosage recommendations possible. Evidence from observational studies suggests that a) pediatric recovery is not necessarily more rapid nor complete than adult recovery; b) principles of neuroplasticity may be applied to pediatric aphasia; however prognostication may be affected by developmental stage and presence of immature language networks; and, c) aphasia symptoms related to literacy may extend into adulthood, even after functional communication has been established. Clinical implications as well as recommendations for research are discussed in light of evidence.

Published: September 2020

In Oman, statistics show that vehicle accidents cause negative effects at the social and economic level resulting in high mortality and injuries. Heavy losses indirectly affect both people and the property of the country. Last year, the percentage of road accidents across Oman was about 33.3% compared to 2017, road accidents accounted for 28.8% less than in 2018. Furthermore, there were many minor accidents in difficult geographic areas in Oman that resulted in deaths because of delay and difficulty the rescues teams had to discover the accidents locations. In order to reduce road traffic fatalities, the rescue teams? took an effective way. They reduced the time between accidents and the emergency team sending to the scene by using detection system via sensors connected in cars. The aim of this project is to propose an advanced system for accident tracking and monitoring. This research targets the result to reduces the number of serious injuries and death tolls and enable the competent authorities to monitor any accident in all vehicles registered at the system. The modified waterfall methodology has been used. This methodology? contains five different stages that contribute to the successful implementation of this system by tracking the project step by step for these stages you can refer to any previous stage in order to amend documents and jobs therein.

The world always faces multiple risk factors due to an increase in traffic accidents. This leads to the death of many people. Some of them get seriously injured and get permanent disabilities due to the negligence of persons in following traffic safety procedures. The General Directorate of Traffic in the Sultanate of Oman is responsible for regulating traffic in the country by monitoring the movement of traffic in the streets of inside cities and outside to preserve the safety of traffic in the streets of the Sultanate of Oman. This research paper aims to provide a solution in educating Omani residents about teaching driving laws, especially in Oman. The solution will raise awareness in the society with the rules and laws related to traffic safety. In order to justify and support the requirements of this research, the researchers conducted interviews and surveys among the public. The methods of data collection included questionnaires and interviews.
The analysis showed that majority of the audience who participated in surveys strongly agreed that such kind of education system for the residents was really essential so that they could learn about the importance of traffic rules and regulations right from their childhood. Finally, the researchers have proposed to develop a mobile app, which would be one of its kind and exclusive in Oman by Royal Oman Police (ROP) – Traffic Safety Unit. The methodology used in the development of this project would be the spiral model. Relevant literature was reviewed in order to study the existing system and also the similar systems which are existing around the world.

Published: September 2020

This paper aims to develop a wheelchair for paralysis patients. The objectives of the paper include Fall detection, Forward bending detection, and SMS service. All these technologies have been covered in terms of their requirements, costs, system design, and system analysis. Fall detection is done using Accelerometer sensor. It detects the fall from the wheelchair of the patient who is having spinal problems. The sensor sends a signal to the controller and activates the buzzer. SMS will also be sent to the caretaker. The second technology used is forward bending detection. It is used for those who are bending their backs in order to inform them to sit properly. Ultrasonic sensor is used for this detection, alarm will be activated and SMS also will be sent. Next technology is the use of SMS service. If the patient is able to move one hand, he can use a keypad and 10 different buttons can be provided for different services. Depending on the keypad pressed, the corresponding SMS will reach the caretaker and the patient will be served accordingly. The proposed work is started after a thorough literature review. Arduino controller is used for getting the signal from the sensor and provide the information to the caretaker and switch ON buzzer. The proposed work is simulated using proteus and then implemented in hardware.
As an extension to the work, fire alarm system and automated wheel movement, live camera can also be added to improve the advantages of the safety wheel chair. The proposed work is funded by Research Council, Oman.

Authors: Al-Hakmani Amna Khamis Salim , Sajan Ajitha 
Published: September 2020

This paper focuses on the design and implementation of a Smart Trolley Shopping in supermarkets to solve difficulties of customers whilst waiting in queues for billing. The trolley is designed to develop market services and make them modern, healthy and easy to use. The remote controls the movement of the trolley automatically and reduces the load on the client during pulling the trolley. In addition, it helps in saving money by not buying unwanted products, with the help of the Liquid Crystal Display in the trolley, which shows on the update of purchase limit. In this work the client writes the amount they have via the keypad, where the amount appears on the liquid crystal screen. The product used is then checked for price and RFID details. This information is sent to RFID in the product via radio to RFID reader which determines the radio waves. It has an antenna bar for receiving and transmitting data. It also contains a small memory for detailed information of up to 256 bytes. The total cost is summarized by the scanner for materials stored in memory, sent to Arduino. The cart moves according to the client's movements when shopping and then moves to the left, right, forward, backward, or even stops through the buttons. If the customer purchases the products more than the amount recorded on the keyboard, an alarm will serve as a reminder to the customer that he/she has exceeded the purchase limit. The smart trolley is characterized by the speed of accounting compared to conventional accounting and provides a quality service. It reduces congestion at the cashier counter and shortens the time and waste of effort during the accounting process.

Published: September 2020

Antacids are substances commonly used by patients to obtain fast symptomatic relief from dyspepsia. They are weak bases which neutralize excess gastric acid and subsequently raise the pH of the gastric contents. The potency of the antacids depends mainly on their acid neutralization capacity (ANC) and this can vary from one brand to another. Several dosage forms of antacids are available for use by patients. However, In Ghana, suspensions are the commonest dosage form of antacids which is preferred by patients.
The objective of this study was to determine the acid neutralizing capacity of six (6) randomly selected brands of antacid suspensions on the Ghanaian market using potentiometric acid-base titration. The samples were coded A-F to avoid any bias in the study. All the sampled brands had more than one year to expiry as indicated on their label.
Brand D had the highest ANC of 29.70 mEq/dose whiles brand A had the lowest ANC of 11.25 mEq/dose. From the results obtained, it can be inferred that acid neutralization can be more effective and rapidly achieved with liquid antacids containing a high amount of magnesium hydroxide and aluminium Hydroxide. Hence, for acute symptomatic relief from dyspepsia, antacids containing a higher concentration of magnesium hydroxide and aluminium hydroxide would be most beneficial to patients.

Authors: Emeka Kevin Mgbe Emeka Kevin Mgbe , Ajare Enyeribe Chuks , Okere Philip 
Published: September 2020

Introduction: There are varied scrotal findings in subfertile males of which ultrasonography is a readily available, non-ionizing and reproducible imaging modality of choice for proper assessment.
Aim: To identify the patterns of scrotal ultrasonographic findings in suspected subfertile males in Enugu.
Study Design: A comparative cross sectional prospective study.
Place and Duration of Study: Department of Radiation Medicine University of Nigeria Teaching Hospital (UNTH) Enugu, between July 2019 and February 2020.
Methodology: 130 adult males comprising 65 suspected subfertile males and 65 normal adult males were recruited for this study. Ultrasound scanning was done on research participants using 5.0-7.5 MHz linear transducer on a mobile “ALOKA” ultrasound machine. The obtained data were coded, validated, and analyzed using Statistical Package for the Social Sciences SPSS software, version 24, percentage, analysis of variance (ANOVA) and t test. A P-value of less than 0.05 was considered statistically significant.
Results: A total of 130 subjects were scanned. The mean age was 41.2years. The mean testicular volume was 10.01±4.09 cm3. There was a wide variety of findings in the assessed subfertile males ranging from normal to inhomogeneous testicular echotexture and varicocoele. Varicocoele was the commonest finding accounting for 50% of other findings, followed by hydrocoele (22%), then 10% had inhomogeneous echotexture while microlithiasis, undescended testis as well as epididymal cyst all had 6%.
Conclusion: Ultrasonographic evaluation of testis is invaluable in the assessment of patterns of findings in male subfertility. Varicocoele was the commonest sonologic finding among the suspected subfertile males. This is reassuring as varicocoele is readily treatable cause of subfertility compared to complex multifactorial causes of female subfertility.
Integral barrier Lyapunov function‐based adaptive fuzzy output feedback control for nonlinear delayed systems with time‐varying full‐state constraints
Authors: Ye Dan , Wang Kaiyu , Yang Haijiao , Zhao Xingang 
Published: September 2020

SummaryIn this article, an adaptive fuzzy output feedback control method is presented for nonlinear time‐delay systems with time‐varying full state constraints and input saturation. To overcome the problem of time‐varying constraints, the integral barrier Lyapunov functions (IBLFs) integrating with dynamic surface control (DSC) are applied for the first time to keep the state from violating constraints. The effects of unknown time delays can be removed by using designed Lyapunov‐Krasovskii functions (LKFs). An auxiliary design system is introduced to solve the problem of input saturation. The unknown nonlinear functions are approximated by the fuzzy logic systems (FLS), and the unmeasured states are estimated by a designed fuzzy observer. The novel controller can guarantee that all signals remain semiglobally uniformly ultimately bounded and satisfactory tracking performance is achieved. Finally, two simulation examples illustrate the effectiveness of the presented control methods.

Published: September 2020

AbstractNatural Aquaporin (AQP) channels are efficient water translocating proteins, rejecting ions. Inspired by this masterpiece of nature, Artificial Water Channels (AWCs) with controlled functional structures, can be potentially used to mimic the AQPs to a certain extent, offering flexible avenues toward biomimetic membranes for water purification. The objective of this paper is to trace the historical development and significant advancements of current reported AWCs. Meanwhile, we attempt to reveal important structural insights and supramolecular self‐assembly principles governing the selective water transport mechanisms, toward innovative AWC‐based biomimetic membranes for desalination.
Bypassing the Inertness of Aziridine/CO2 Systems to Access 5‐Aryl‐2‐Oxazolidinones: Catalyst‐Free Synthesis Under Ambient Conditions
Authors: Bresciani Giulio , Antico Emanuele , Ciancaleoni Gianluca , Zacchini Stefano , Pampaloni Guido , Marchetti Fabio 
Published: September 2020

AbstractThe development of sustainable synthetic routes to access valuable oxazolidinones via CO2 fixation is an active research area, and the aziridine/carbon dioxide coupling has aroused a considerable interest. This reaction features a high activation barrier and thus requires a catalytic system, and may present some other critical issues. Here, the straightforward gram‐scale synthesis of a series of 5‐aryl‐2‐oxazolidinones was developed at ambient temperature and atmospheric CO2 pressure, in the absence of any catalyst/co‐catalyst. The key to this innovative procedure consists in the direct transfer of the pre‐formed amine/CO2 adduct (carbamate) to common aziridine precursors (dimethylsulfonium salts), replacing the classical sequential addition of amine (intermediate isolation of aziridine) and then CO2. The reaction mechanism was investigated by NMR spectroscopy and DFT calculations applied to model cases.

Published: September 2020

AbstractSARS‐CoV‐2, the causing agent of the ongoing COVID‐19 pandemic, is a beta‐coronavirus which has 80% genetic homology with SARS‐CoV, but displays increased virulence and transmissibility. Initially, SARS‐CoV‐2 was considered a respiratory virus generally causing a mild disease, only severe and fatal in the elderly and individuals with underlying conditions. Severe illnesses and fatalities were attributed to a cytokine storm, an excessive response from the host immune system. However, with the number of infections over 10 millions and still soaring, the insidious and stealthy nature of the virus has emerged, as it causes a vast array of diverse unexpected symptoms among infected individuals, including the young and healthy. It has become evident that besides infecting the respiratory tract, SARS‐CoV‐2 can affect many organs, possibly through the infection of the endothelium. This review presents an overview of our learning curve with the novel virus emergence, transmission, pathology, biological properties and host‐interactions. It also briefly describes remedial measures taken until an effective vaccine is available, that is non‐pharmaceutical interventions to reduce the viral spread and the repurposing of existing drugs, approved or in development for other conditions to eliminate the virus or mitigate the cytokine storm.
High risk of Clostridium difficile infection among spinal cord injured patients after the use of antibiotics commonly used to treat urinary tract infections

Published: September 2020

AbstractAimTo characterize the use of common urinary tract infections (UTI)‐relevant antibiotics after an SCI and determine the risk of Clostridium difficile infection (CDI) from these antibiotics.MethodsWe used routinely collected data from Ontario (Canada) to conduct a retrospective, cohort study. We identified people >18 years of age with a traumatic SCI between April 2003 and March 2017. The primary exposure was an outpatient UTI‐relevant antibiotic prescription during our observation period, and the primary outcome was evidence of a CDI. An adjusted cox proportional hazards model was used, and antibiotic exposure was modeled as a categorical, time‐varying variable based on whether the patient likely had a UTI or not.ResultsWe identified 2528 people with SCI; 1642 (65%) were exposed at least once to an antibiotic of interest. The most commonly prescribed UTI‐relevant antibiotic was fluoroquinolone (34%). Most patients did not have investigations for a UTI before the use of any of the different antibiotic classes. A small number of patients (5%) used chronic (>3 months) UTI‐relevant antibiotics. The overall proportion of patients diagnosed with CDI was 7.4% (9.3/10 000 patient‐days). The adjusted hazard ratio for CDI within 30 days was 3.5 (95% confidence interval, 1.9–6.7, p < .01) if they were exposed to a UTI‐relevant antibiotic likely associated with a UTI, which was similar to the risk from UTI‐relevant antibiotics which may not have been for a UTI.ConclusionsThe rate of CDI is high in this population and outpatient antibiotics that are commonly used for UTIs are a significant risk factor for CDI.
Explaining Recurrent Machine Learning Models: Integral Privacy Revisited
Authors: Torra Vicenç , Navarro-Arribas Guillermo , Galván Edgar 
Published: September 2020

Abstract
We have recently introduced a privacy model for statistical and machine learning models called integral privacy. A model extracted from a database or, in general, the output of a function satisfies integral privacy when the number of generators of this model is sufficiently large and diverse. In this paper we show how the maximal c-consensus meets problem can be used to study the databases that generate an integrally private solution. We also introduce a definition of integral privacy based on minimal sets in terms of this maximal c-consensus meets problem.
