Filtration of radioaerosols in Nuclear Power Plant Paks, Hungary

Abstract: The detrimental effect of the inhalation of hazardous materials in form of aerosols is known and the effect of the particle size on their deposition in the respiratory system is similarly to industrial aerosol filters, the minima of the deposition occurring at 0.1–0.3 µm of particle size. In case of industrial aerosol filters therefore, it is desirable that their efficiency be sufficiently high for 0.3 µm particle size as well. In this paper, the aerosol types, their filtration mechanism and the industrial filters are reviewed. The methodology and experience of the filter efficiency measurements at Nuclear Power Plant Paks site in Hungary is also presented.

Study on folds of monolayer sandwiched-in different thickness terranes

Abstract: The paper discussed the limitation of ‘Dominant wavelength theory’. The theoretical model and nonhomogeneous differential equation of fold and deformation of a monolayer sandwiched-in limited and different thickness terranes are proposed by using mechanics of elasticity. In addition, the “Dominant wavelength theory’ is proved by the experimental folding in elastic materials. The folds of a monolayer sandwiched-in limited and different thickness terranes are studied inside and are explored in the field.

COVID-19 in Pakistan

Abstract: Security, in a non-traditional sense, is an inclusive and comprehensive concept that covers various facets of human life including public health. But the South Asian security agenda has always been dominated by a traditional and state-centric approach, leaving little or no space for non-traditional security issues including but not limited to environmental degradation, repression, hunger, and disease. Pakistan is no exception where health security or public health has always remained on the margins of the country’s overall security agenda. Therefore, Pakistan was caught off-guard and ill-prepared when COVID-19 struck the country in February 2020. The current chapter seeks to document the impact of COVID-19 on Pakistan’s various security sectors including economic, environmental, societal, and conventional security, and government’s response and outcomes. The chapter concludes that the economic fallout caused by coronavirus can potentially hit the sectarian and ethnic fault lines of the country and restrict Pakistan’s conventional options to respond to Indian belligerence during the pandemic. Rather, cooperation on dealing with non-traditional security threats such as COVID-19 will offer a rare window of opportunity to partner in a noble cause to protect billions of South Asians against the modern plague.

Tooth mortality in concurrent cigarettes smoking and Khat chewing in Yemeni population

Abstract: This study aims to explore tooth mortality in Khat chewer smokers (KS) and Khat chewer nonsmokers (KNS) in a selected population from Sana’a, Yemen. A total of 1296 persons, 858 were male and 438 were female ranging in age from 15 to 64 years were examined. The samples of individuals were divided into two groups: KS and KNS. The number of tooth loss per person was calculated and data were analyzed with SPSS version 16. There was a significant difference in the percentage of lost teeth between the KS and KNS groups (p= 0.001). The highest percentage of tooth loss was observed in the first and second molar teeth. Male KNS had significantly more teeth loss for second premolar, first and second molars compared to smoker khat chewers. In this study sample, the first and second molars being the most commonly missing teeth among Khat chewing non-smokers. The central and lateral incisors were the most commonly missing teeth in Khat chewing smokers. Clinical article (J Int Dent Med Res 2017; 10(3): pp. 899-904)
