The equaliser is an indispensable block inside the receiver in Serial Link systems. It is used to moderate the high-frequency loss of the signal in the channel. A new technique is described to improve the performance of the Continuous-Time Linear Equaliser (CTLE). This technique utilises split-length device (SLD) in order to boost the output impedance of the SLD. The proposed CTLE is designed and simulated in 65 nm CMOS technology. Post-layout simulation results demonstrate that the proposed technique has more peaking than conventional CTLE by an order of 1.5 dB at Nyquist frequency. The Proposed design has a vertical eye-opening of 220 mV and a horizontal eye-opening of 0.35 UI. It consumes 1.56 mW from a 1.2 V supply. A FoM of 13.1 fJ/bit/dB is achieved. [ABSTRACT FROM AUTHOR]

Workplace violence (WPV) is a serious endemic phenomenon in healthcare settings, and it has been escalating during the COVID-19 pandemic. In this cross-sectional study, healthcare workers (HCWs) (105 physicians and 104 nurses) working at two public hospitals accepting patients with COVID-19 in Egypt were included. Using a self-administered questionnaire distributed in January 2021, data about HCWs' sociodemographic and occupational characteristics and their exposure to psychological and physical WPV during the past six months were collected. The results showed that the prevalence of psychological and physical WPV was 42.6% and 9.6%, respectively. Relatives of patients were the perpetrators in most WPV incidents. HCWs did not report 57.3% of psychological and 10.0% of physical WPV incidents. Female sex, having physical contact with patients, and working rotational shifts were associated with the increased exposure to psychological and physical WPV. In conclusion, this study showed a high prevalence of WPV against HCWs in Egyptian public hospitals during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

The purpose of the paper is to report the findings of Saudi researchers' academic performance on the topic of COVID-19. In addition, the paper explored the contribution of Saudi Arabia in the area and how Saudi Arabia is doing compared to other Arab countries The study adopted bibliometrix R to map the literature on the topic published by Saudi scholars. A total number of 3242 documents were retrieved from the Web of Science database and examined Using the software to mine information about journals, articles, authors, citations, keywords and countries. The analysis revealed that Saudi scholars had published a fair amount of COVID-19 studies in a small timespan. Scholars from Saudi Arabia have initiated a strong collaboration with other researchers worldwide. The data revealed that Saudi scholars have collaborated with scholars All over the world. Overall, Saudi Arabia had its share of global contribution on the subject (19th place). Contribution from Saudi Arabia was found to be affiliated to other countries, especially the USA and Egypt The study focused only on Saudi scholars' productivity in the field of COVID-19. More research needs to be done in order to find how Arab scholars are progressing with COVID-19 research. Additionally, the study only used the Web of science to retrieve the data. Using Scopus might give us more understanding of the scholars' productivity in the field. Despite several studies on the field, this is the first study covering scholars' productivity in covid-19 in the Middle east. The results of the study are hoped to help in understanding the research progress in this area and how scholars collaborate in COVID-19 research. [ABSTRACT FROM AUTHOR]

Social media platforms have become an essential source of information for many users. The purpose of the current study is to explore Egyptian social media users' perceptions and behavior in the context of COVID-19 misinformation. The study was conducted in two stages; the first included identifying and categorizing misinformation shared in the Arabic language on Egyptian social media pages, and the second stage involved distributing a questionnaire to capture the users' perceptions and behavior. The study utilized a mixed-methods approach to achieve the research objectives. In all, 1304 questionnaires were retrieved. The findings of the study showed that there are four main types of misinformation shared on social media. The first type is false claims about the virus or treatment of the virus; the second is false information about the government; the third is false content in general or manipulated content, and the last type is conspiracy theories. The findings also revealed that gender and education affect how people deal with and accept misinformation. Additionally, it was found that the spread of COVID-19 misinformation has caused negative feelings among the participants. The study was conducted on a sample of Egyptian participants and Egyptian social media pages on Facebook, hence, the types of misinformation and the results may differ in other countries, depending on the social media platform and other factors that may play a role in the spread of misinformation.

In this study an attempt is taken to evaluate the performance of basalt FRP bars compared with carbon FRP bars and conventional steel bars. Specimens of reinforced concrete will be casted to fulfil this comparison. These beams will comprise a common top reinforcement, stirrups spacing, and concrete properties. The difference is in the bottom reinforcement where it was once steel, Carbon FRP, Basalt FRP, and a hybrid of Basalt FRP and steel. These beams were tested for their behaviour under a flexural load through a four-point bending test. The remaining specimens were casted as columns with common stirrups spacing, and concrete properties. The behaviour of Basalt FRP, Carbon FRP, and steel reinforcement will be tested upon the application of an axial compressive load. The bonding strength between concrete and the different candidate bars is tested through the bond pull-out test. Furthermore, tests will be conducted on the thermal, chemical, and mechanical properties of the individual bars. This study is expected to yield an evaluation of the main characteristics of the newly developed Basalt FRP bars and an identification of the key differences and limitations of using BFRP in concrete structures in relation to CRFP and traditional steel reinforcement of concrete structure.
