<p>The Cathode ray tubes (CRTs) represent more than 70% of global e-waste sets. The glass of the CRT is doped with lead to prevent emission of radiations especially electrons. The glass at the panel and neck of the CRT along with the cement mortar, a mixture of 70% neck glass and 30% cement (mix70), are investigated mathematically as shielding materials from photons having energies in the range 0.06-3 (MeV). Experimentally the material mix70 is tested at energies 0.238 and 0.583 (MeV). Good agreement was recognized between the calculated shielding parameters and that obtained experimenta

This study evaluates the efficiency of lead (Pb) extraction from spent leaded glass in strongly alkaline solution after mechanical activation in a planetary ball mill as the chemical breakage and defects formed in the inner structures will contribute to the easy dissolution of the activated leaded glass. The influence of rotate speed and time of mechanical activation, NaOH concentrations, leaching temperature, phase ratios (v/w) had been studied. More than 78% of Pb extraction can be achieved after mechanical activation, compared with 3.5% Pb extraction for chemical leaching of non-activated s

With regard to dynamic mechanical analysis (DMA), PLA does not have the classical behavior of a thermoplastic polymer. Often, overlapping events (enthalpic relaxation, glass transition and crystallization) that occur as the temperature increases make the DMA result of a PLA l

Since few years, there has been an increasing interest and demand in flexible electronics. Standard imaging system consists of an optical module (set of lenses) and an image sensor. For wide field of view applications, and due to the curved shape of lenses and mirrors, the flat image after being propagated through the optical system is not flat but curved, i.e. the off-axis light focuses in a curved manner. This problem is called Petzval Field Curvature Aberration (Petzval FCA). It is generally fixed by additional complex lenses to “flatten” the image plane. We propose another approach with a

Working women worldwide have faced career difficulties. Examples of this include women academic leaders in India where negative cultural beliefs about women moving to the top-management positions (also referred to as glass ceiling) still exist. Although they are highly educated and competent workers, they have unequal opportunities to be organizational leaders or top executives. Academic women with greater knowledge and abilities can actually perform as academic leaders, and they can support educational development of the country. Government and educational institutions should realize the pote

This study aimed at bridging this gap and proposed a Three-Dimensional Model (Macro, Meso, and Micro). It also attempted to gain a deeper understanding of the nature of the glass ceiling, which limits women's participation in higher decision-making positions and determined how to overcome these barriers. The study adopted a mixed-methods approach. Three exploratory workshops involving 65 academic women leaders were conducted at three Saudi universities. This was followed by a field survey of the overall population involving 213 female leaders. Then six interviews of 35 female leaders were cond

Abstract Do women and racial/ethnic minority leaders pay a risk tax on their way to the top? Theories of the glass cliff have focused on the penalties imposed upon women and minority leaders due to bias and discrimination at the time of appointment to top leadership positions. Much less attention has focused on the strategic agency these leaders exercise in response to bias across the career. This paper advances theory and research on the glass cliff by analyzing the choices, decisions, and priorities of white women and people of color that, across the career, result in their appointment to gl

AbstractLarge volumes of depleted natural and low-enriched uranium exist in the UK waste inventory. This work reports on initial investigations of the leaching performance of candidate glass and cement encapsulation matrices containing UO3 powder as well as that of uranium oxide powders. The surface areas of UO3 powder and the monolith samples of UO3 conditioned in the glass and cement matrices were very different making leaching comparisons difficult. The results showed that for both types of monolith conditioned samples a steady increase of uranium concentration in solution with time was gen
