Investigation of Noise Pollution of Electrical Diesel Generators in Duhok City/ Kurdistan of Iraq

The City of Duhok, Kurdistan region of Iraq, whilst has been subjected to persistent fast development and urbanization and expansion of economy, travel and tourism, it is still suffering from the shortage of public electricity supply since 1990. This leads to widely depending on diesel electricity generators. This study investigates diesel generators noise pollution in Duhok city. An empirical correlation formula was deduced for the mean noise level of 30 diesel generator sites as a function of distance for the 50 meters range, and then this correlation is extrapolated up to 80 m from the sites. The results showed that the measured mean noise level at 50 m from the generator sites was 74.86 dB(A) which is higher than the permissible noise level for residential and commercial areas that are 55 dB(A) and 65 dB(A) respectively, while it is near the industrial areas which equals 75 dB(A). On making the extrapolation to the empirical formula to compare distance up to 80 m from the sites, the extrapolated mean noise level reduced to 71.1 dB(A) which is still beyond the permissible noise level for residential and commercial areas

The Impact of Psychosocial Factors of Physical Health Outcomes: A Review of the Biopsychosocial Model in Family Medicine

Discontent with the biological model of illness—which is still the predominant healthcare model—led to the development of the biopsychosocial model, which was described in Engel's seminal Science paper forty years ago. It is the foundation of the International Classification of Functioning (WHO ICF) developed by the World Health Organization Clinical outcomes for functional disorders and chronic diseases treated in family medicine may be improved by the biopsychosocial approach. Since clinical performance metrics and standards are biomedically focused, family medicine doctors have no financial incentive to implement the biopsychosocial paradigm in their practices. Implementing the biopsychosocial approach in family medicine may be hampered by workload and incompetence

Global emerging Omicron variant of SARS-CoV-2: Impacts, challenges and strategies

Newly emerging variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are continuously posing high global public health concerns and panic resulting in waves of coronavirus disease 2019 (COVID-19) pandemic. Depending on the extent of genomic variations, mutations and adaptation, few of the variants gain the ability to spread quickly across many countries, acquire higher virulency and ability to cause severe disease, morbidity and mortality. These variants have been implicated in lessening the efficacy of the current COVID-19 vaccines and immunotherapies resulting in break-through viral infections in vaccinated individuals and recovered patients. Altogether, these could hinder the protective herd immunity to be achieved through the ongoing progressive COVID-19 vaccination. Currently, the only variant of interest of SARS-CoV-2 is Omicron that was first identified in South Africa. In this review, we present the overview on the emerging SARS-CoV-2 variants with a special focus on the Omicron variant, its lineages and hybrid variants. We discuss the hypotheses of the origin, genetic change and underlying molecular mechanism behind higher transmissibility and immune escape of Omicron variant. Major concerns related to Omicron including the efficacy of the current available immunotherapeutics and vaccines, transmissibility, disease severity, and mortality are discussed. In the last part, challenges and strategies to counter Omicron variant, its lineages and hybrid variants amid the ongoing COVID-19 pandemic are presented
