Major sporting events amid monkeypox and COVID-19 outbreaks: Considering the impact upon the traveller
No full textAcross 2022, international travel began to return to more typical patterns, including spectators at major sporting events. For example, in October 2022, the T20 cricket world cup is being held in Australia, and the football world cup begins in Qatar in the Middle East in November 2022. These events would be attended by several hundred thousand visitors from multiple countries. However, the COVID-19 pandemic is far from over, and the monkeypox outbreak has also been declared a global emergency. Organizing sports events under such conditions pose specific challenges for organizers. However, measures taken to prevent the spread of these infections also influence the ability of spectators to travel and their experiences when they arrive..

Analyzing the early age behavior of Continuously Reinforced Concrete Pavements (CRCP) under their environmental loading
No full textThis thesis investigates the behavior of Continuously Reinforced Concrete Pavements
(CRCP) with respect to material properties, environmental conditions, and longitudinal
reinforcement depths, focusing on their effects on stress distribution and horizontal cracking.
CRCPs are crucial for the durability of transportation infrastructure, requiring an in-depth
understanding of their performance under various conditions to ensure longevity and resilience.
An advanced analytical approach using ANSYS software was employed to model and
evaluate CRCP responses under one hundred forty-four different scenarios. Key factors analyzed
include aggregate characteristics, reinforcement positions, temperature variations, and moisture
content. The study also examines the impact of various longitudinal reinforcement depths and
configurations on stress distribution and the propensity for horizontal cracking within CRCPs.
The key findings include:
1. Temperature Variations: Larger temperature drops significantly increase Maximum
Normal Stresses, exacerbating the risk of horizontal cracking.
2. Material Properties: Higher modulus of elasticity and CoTE values lead to greater stress
levels and deformation.
3. Reinforcement Configuration: Mid-depth reinforcement results in lower stress
concentrations compared to top reinforcement.
4. Environmental Conditions: Increased drying shrinkage leads to higher stress and
deformation, highlighting the importance of moisture management in CRCP design.
The detailed stress analysis provides quantitative data for refining CRCP design
guidelines, optimizing reinforcement strategies, improving material selection, and adapting
designs for diverse environmental conditions. These insights contribute to the development of
more resilient and durable pavement structures
Large-area high-throughput synthesis of monolayer graphene sheet by Hot filament thermal chemical vapor deposition
No full text[EN] We report hot filament thermal CVD (HFTCVD) as a new hybrid of hot filament and thermal CVD and demonstrate its feasibility by producing high quality large area strictly monolayer graphene films on Cu substrates. Gradient in gas composition and flow rate that arises due to smart placement of the substrate inside the Ta filament wound alumina tube accompanied by radical formation on Ta due to precracking coupled with substrate mediated physicochemical processes like diffusion, polymerization etc., led to graphene growth. We further confirmed our mechanistic hypothesis by depositing graphene on Ni and SiO 2/Si substrates. HFTCVD can be further extended to dope graphene with various heteroatoms (H, N, and B, etc.,), combine with functional materials (diamond, carbon nanotubes etc.,) and can be extended to all other materials (Si, SiO 2, SiC etc.,) and processes (initiator polymerization, TFT processing) possible by HFCVD and thermal CVD.This research work was supported by the grant received by Manoj Kumar Singh from FCT (Grant No. PTDC/CTM-NAN/121108/2010), Ministry of Science and Technology, Portugal.

Most prolific keywords in titles were: Bose-Einstein condensate (38), Bose-Einstein condensation (15), Observation (9), Helium hydride (8), Emission spectrum, (6) Suppression (4). The ‘biobibliometrics’ term is used for a method of retrieving and visualizing biological information that uses co-occurrence of gene naming terms in Medical Sciences to generate semantic links between genes. Therefore it is suggested that ‘Scientometric Portrait’ is the appropriate phrase for the studies on scientists and ‘Informetric Portrait’ for the studies pertaining to researchers in other disciplines such as arts, humanities, and social sciences
H. J. Bhabha : a case study of synchronous references
No full textQuantitative analysis of the events of synchronous references in the research papers followed throughout the publishing career of an individual scientist revealed interesting highlights on the knowledge-generating-system. In the case study of Homi Jehangir Bhabha first quinquennium and fifth quinquennium of his research career had low Self-references; third quinquennium and fourth quinquennium had moderate Self-references; whereas second quinquennium had highest Self-references. The two major clusters of Self-references occurring during the second and third quinquennium were indicators of active periods of knowledgegenerating and faster communications.(Revised version published in 2006 in International Journal of Nuclear Knowledge Management,Vol.2.

There have been 60,000 cases reported worldwide, most of which are in places where monkeypox has never been seen due to the travel of people who have the virus. This research aims to evaluate the general Arabic population in regard to the monkeypox disease, fears, and vaccine adoption after the WHO proclaimed a monkeypox epidemic and to compare these attitudes to those of the COVID-19 pandemic. Methods: This cross-sectional study was performed in some Arabic countries (Syria, Egypt, Qatar, Yemen, Jordan, Sudan, Algeria, and Iraq) between 18 August and 7 September 2022. The inclusion criteria were the general public residing in Arabic nations and being older than 18. This questionnaire has 32 questions separated into three sections: sociodemographic variables, prior COVID-19 exposure, and COVID-19 vaccination history. The second portion assesses the knowledge and anxieties about monkeypox, while the third section includes the generalized anxiety disorder (GAD7) scale. Logistic regression analyses were performed to compute the adjusted odds ratios (aOR) and their confidence intervals (95%CI) using STATA (version 17.0). Results: A total of 3665 respondents from 17 Arabic countries were involved in this study. Almost two-thirds (n = 2427, 66.2%) of the participants expressed more worry about COVID-19 than monkeypox diseases. Regarding the major cause for concern about monkeypox, 39.5% of participants attributed their anxiety to the fear that they or a member of their family may contract the illness, while 38.4% were concerned about monkeypox becoming another worldwide pandemic. According to the GAD 7 score, 71.7% of the respondents showed very low anxiety toward monkeypox and 43.8% of the participants scored poor levels of knowledge about monkeypox disease. Participants with previous COVID-19 infection showed a 1.206 times greater acceptance to receive the monkeypox vaccine than those with no previous infection. A 3.097 times higher concern for monkeypox than COVID-19 was shown by the participants who perceived monkeypox as dangerous and virulent than those who did not. Participants who have a chronic disease (aOR: 1.32; 95%CI: 1.09-1.60); participants worried about monkeypox (aOR: 1.21; 95%CI: 1.04-1.40), and perceived monkeypox as a dangerous and virulent disease (aOR: 2.25; 95%CI: 1.92-2.65); and excellent knowledge level (aOR: 2.28; 95%CI: 1.79-2.90) have emerged as significant predictors. Conclusions: Our study reported that three-fourths of the participants were more concerned about COVID-19 than monkeypox disease. In addition, most of the participants have inadequate levels of knowledge regarding monkeypox disease. Hence, immediate action should be taken to address this problem. Consequently, learning about monkeypox and spreading information about its prevention is crucial.Science Citation Index Expande
