In the present paper, the problem of low velocity impact of plates made from different configurations of ceramic, aluminum, steel and composite (S-glass polyester) is analyzed numerically using Abaqus finite element software. The projectile is assumed to be a rigid body with a hemispherical head. Also, for ceramic layers, Holmquist constitutive model, for aluminum and steel layers, Johnson Coo...
In the present paper, a numerical study is performed to investigate the response of different plates aluminum alloys subjected to low velocity impact condition. In this regard, the square AA5083-H116 aluminum plates with dimensions 300×300 and 3 mm and 5 mm thick under low velocity impact are modelled, and a mesh convergence study is carried out to decide the appropriate number of elements. In ...
Microfinance institutions are considered as an effective tool for achieving the objective of financial inclusion. To achieve this objective it is necessitate that MFIs should be sustainable while reaching the poorest of poor. After the Andhra Pradesh Microfinance Crisis, 2010 sustainability and outreach of MFIs in India is doubtful and questionable. Present paper attempts to look into various d...
Health impact assessment (HIA) methods are used to evaluate the impact on health of policies and projects in community design, transportation planning, and other areas outside traditional public health concerns. At an October 2004 workshop, domestic and international experts explored issues associated with advancing the use of HIA methods by local health departments, planning commissions, and o...
A pulsed crossed beam technique is used to measure ionization cross-sections of metallic atoms. Relative values of cross-sections of single, double and triple ionization of magnesium have been successfully measured with good accuracy over the 0-700 eV range. Absolute values of cross-sections have been obtained by normalization to a theoretical value at high electron energy. Results are compared...
The paper examines the role of executive compensation in inducing management behavior that triggers private securities litigation. Incentive pay in the form of options is found to increase the probability of securities class action lawsuits, holding constant a wide range of other firm characteristics. In contrast, base pay levels and share ownership do not have a significant impact on lawsuit i...
Most impact tests are carried out on specimens with specific stacking sequence and dimensions to meet standard and experimental limitations. The damaged areas and the resulted reduction in the strength values of specimens may not agree very well with those of real application. In this paper an attempt is made to study the variation in the size of damaged areas due to varying the dimension of te...
Background: Impact factor is still a suitable index of evaluating effectiveness of medical journals. The present study was designed to determine the impact factor and immediacy index of Persian medical journals in order to aware authors and librarians of journals status. Materials and methods: For this analytical study, impact factor of 38 Persian medical journals (of 90 approved medical journ...
Health impact assessment (HIA) is a prospective decision-making aid tool that aims to improve the quality of policies, programmes or projects through recommendations that promote health. It identifies how and through which pathways a decision can impact a wide range of health determinants and seeks to define the distribution of effects within populations, thereby raising the issue of equity. HI...
