Broadband dielectric constant measurements in the frequency range between 40 Hz and 50 GHz of pure water, tap water, and sodium chloride aqueous solutions with different DC conductivities up to 5 S/m were conducted. The measurements were done using an impedance analyzer for the frequency range 40 Hz to 110 MHz and a vector network analyzer for 10 M

Modeling the spring-back requires tool-laminate interaction to be taken into account. In this study, an interface based on orthotropic linear behavior coupled with an out-of-plane shear stress failure was proposed to simulate the tool-laminate interaction. The results from this particular model captured the out-of-plane shear stress distribution. T

Numerical calculations of current distribution due to spark discharge on water surface of 0.07 S/m and 5 S/m conductivity were done using two-dimensional axial-symmetry model. In this work, only the water phase is taken into account as the first step to a complete two-phase gas-liquid model. Electric potential on water surface with filamentary disc

The Muslim world hosts a wide diversity of minority groups in terms of ethnicity, religion, language and culture. The minority diversity in some countries is overwhelming compared to others. Such diversities have put the countries in difficult position for national unification in the nation-building process. This article examines the minority polic

Political stability is desired by every state. But is it contingent upon regime types or party systems? Existing studies on political stability suggest that regimes such as authoritarianism, democracy, and dictatorship and their variants have variously influenced political stability. Some have proved to be friendly with political stability in certa

Cryptography refers to protecting transmitted information from unauthorized interception or tampering, while cryptanalysis is art of breaking such secret ciphers and reading information, or perhaps replacing it with different information. The research highlights a new encryption technique called randomized text encryption. The algorithm proposed in

The present study was conducted to determine the effect of air (AD), oven (OD) and freeze drying (FD) on the free radical scavenging activity and total phenolic content (TPC) of Cosmos caudatus and the effect of storage time by the comparison with a fresh sample (FS). Among the three drying methods that were used, AD resulted in the highest free ra

The Millennium Development Goals (MDGs) are a noble initiative to deal with certain chronic socioeconomic problems of the backward societies. Targeted to achieve eight major goals by 2015, the initiative deserves critical assessment of its achievement and strategies as its time frame is approaching to an end. Based on data on the goals achievement

With the growing number of population suffering of gastro-related diseases such as ulcer and gastritis, the need to find novel halal pharmaceutical ingredients with gastroprotective activity is also increasing significantly, especially among the Muslim population. The conventional antiulcer drugs are over shaded with unwanted side effects. Plant ki

Organic contaminants from industrial and/or domestic effluents may be harmful to humans directly or indirectly by degrading the quality of the environment. Consequently these contaminants must be reduced to levels that are not harmful to humans and the environment before disposal. Among the available chemical methods heterogeneous photocatalytic ox
