COVID-19 and the effect of its infodemic on people’s wellbeing

In this research, it was used to look at social media behaviour during the pandemic and how it might have affected well-being. The WHO-5 Well-Being Index (WHO-5) score was used to do this. COVID-19-related material was sought for and disseminated through social media by those who participated in the study. This research shows how social media might affect people's well-being during this epidemic and other crisis in the future. 73 percent of the 993 participants were women, 91 percent were university graduates, and 50 percent worked in diverse occupations, with 20 percent working in health care. Participants said they got COVID-19-related news mostly via social media and messaging apps, with WhatsApp being the most popular. After authentication, the majority of participants said they shared information. Throughout the coronavirus pandemic, this research offers insight into the usage of Social Media and its influence on well-being. During catastrophes and disasters, social media behaviours may have an influence on public safety. There is also a need for global and local health authorities to better prepare for future challenges by developing policies and actions that address these difficulties. Social media activities may directly affect one's mental health, but more research is required before conclusions can be drawn

Goiter and Laryngopharyngeal Reflux

The purpose of this study is to look at the prevalence of laryngopharyngeal reflux disease in patients with goiter in a group of 52 patients with goiter. All participants were asked to respond to the 9 questions on the Reflux Symptom Index (RSI). A diagnosis of LPRD based on symptoms was made for any RSI score above 10. The average score of every question was computed for all patients with goiter and compared to the corresponding average score of the controls. A P value of less than 0.05 was considered statistically significant. The total prevalence of LPRD in patients with goiter as indicated by an RSI score greater than 10 was 15.4% versus 9.1% in controls. The difference was not statistically significant (P value 0.525). Looking at the average score of the individual symptoms as listed in the RSI questionnaire, the average score of all the symptoms was higher in patients with goiter versus controls. There was no correlation between LPRD and any of the demographic variables except for nodules (P value 0.035). The presence of laryngopharyngeal symptoms in patients with goiter should alert the treating physician to the presence of laryngopharyngeal reflux disease

Dynamic Traffic Light System to Reduce The Waiting Time of Emergency Vehicles at Intersections within IoT Environment

Traditional traffic light system, which works based on fixed cycle can be a main reason for traffic jam, due to lack of adaptation to road conditions. Traffic jam has a bad impact on drivers and road users due to the time delay it causes for road users to reach their destinations. This delay can cause a life threat in case of emergency vehicles, such as ambulance vehicles and police cars. One key solution to solve traffic jam on intersections is the dynamic traffic lights, where traffic light operation adapts based on the intersection traffic conditions. Since few of researches projects in the literature interested in solving traffic jam problem for emergency vehicles, the contribution of this paper is to introduces a novel approach to operate traffic light system. The new approach consists of two algorithms which are pure operation mode and hybrid operation mode. These operation modes aim to reduce the waiting time of emergency vehicles on traffic intersections. They assume that there is a smart infrastructure system uses Internet of Things (IoT) that can detect emergency vehicles arrival to an intersection. The smart infrastructure system switches traffic light operation from fixed cycle mode to dynamic mode. The dynamic mode manages traffic lights at intersections to reduce the waiting time of emergency vehicles. The paper presents a simulation of the proposed algorithms, highlights their advantages. In order to evaluate the efficiency of the new technique, we compared our approach with Wen algorithm in the literature and the Traditional traffic light system. Our evaluation study indicated that the proposed algorithms outperformed Wen technique and the Traditional system under different traffic scenario

Supramolecular Interactions Involved in the Solid State Structure of N,N\u27-[bis(pyridin-2-yl)formylidene]ethane-1,2-diamine

The structure of the symmetrical Schiff base, N,N\u27-[bis(pyridin-2-yl)formylidene]ethane-1,2-diamine (bpfd) has been characterized by single crystal X-ray diffraction. The non-covalent supramolecular chemistry involved in the crystal structure of this ligand has been carefully investigated. The structure adopted different motifs of nitrogen-hydrogen interactions that led to the formation of centrosymmetric dimers. In addition, edge-edge and face-face nitrogen-nitrogen interactions were ob-served and reported. The Schiff base (bpfd) ligand crystallizes in a monoclinic space group C12/c1 with a = 19.128(2) Å; b = 5.8776(6) Å; c = 13.1403(15) Å; α = 90o; β = 121.970o(4); γ = 90o and z = 4. This structure is an example of compounds with many symmetry-independent molecules in the asymmetric unit cell (Z > 2)
