Quantum computer is the current topic of research in the field of computational science, which uses principles of quantum mechanics. Quantum computers will be much more powerful than the classical computer due to its enormous computational speed. Recent developments in quantum computers which are based on the laws of quantum mechanics, shows different ways of performing efficient calculations along with the various results which are not possible on the classical computers in an efficient period of time. One of the most striking results that have obtained on the quantum computers is the prime factorization of the large integer in a polynomial time. The idea of involvement of the quantum mechanics for the computational purpose is outlined briefly in the present work that reflects the importance and advantages of the next generation of the 21st century classical computers, named as quantum computers, in terms of the cost as well as time period required for the computation purpose. Present paper presents a quantum computer simulator for executing the limitations of classical computer with respect to time & the number of digits of a composite integer used for calculating its prime factors.

Phytopathogenic fungal cultures were isolated from infected tomato plants and identified on the basis of morphological and cultural characters as Pythium and Fusarium species. One hundred thermostable bacterial cultures were isolated from rhizosphere soil samples of healthy tomato plants, on nutrient agar and putatively identified as Bacillus species on the basis of morphological characters and sporulation ability. These isolates were tested for primary screening of antagonists against phytopathogenic Fusarium and Pythium species, by dual culture method on potato dextrose agar (PDA) plates. The isolates showing positive results were tested for their antifungal potency using seed plate and dual broth culture technique. Four potent antifungal Bacillus isolates were identified to species level on the basis of biochemical characters and 16S r-RNA sequencing as B. thuringiensis184, B. cereus 220, B. cereus 228 and B. subtilis 252. The extent of antifungal activity was higher in dual broth culture than seed plate method. These potent antifungal Bacillus isolates were used to prepare bioformulations and found significant to protect tomato plants from fungal infections. © Global Science Publications. Source

Growing interest in developing new materials for device applications led to study of ferroelectric oxides in a wide range and variety of compositions. In the present work, polycrystalline samples of lead barium strontium titanate (Pb 1-xBa 0.5xSr 0.5xTiO 3) solid solution system have been synthesized. Phase formation studies and crystal structure analysis were carried out by X ray diffractometry at room temperature, which suggested formation of single phase compound with tetragonal structure up to x∈=∈0.8 and cubic structure for x∈=∈1.0. The XRD pattern has been analyzed by employing Rietveld method. The phase transition in the system was confirmed by Differential Scanning Calorimetry (DSC). Samples with 0.0>x>0.8 are in ferroelectric state whereas with x∈=∈1.0 is found to be in paraelectric state at room temperature. Co-substitution of Ba 2+ and Sr 2+ into lead titanate shows reduction in anisotropy as well as porosity. The dielectric studies of the system as a function of temperature and frequency were carried out in the range 323 K to 773 K and 100 Hz to 1 MHz respectively. Variation of dielectric constant and loss tangent with temperature shows peaking effect near Curie temperature. Frequency dependant dielectric studies clearly show that the dielectric constant and loss tangent decrease exponentially with increased frequency. © 2012 Springer Science+Business Media, LLC. Source

The concept of time dependent Schrödinger equation (TDSE) illustrated in literature and even during class room teaching is mostly either complex or meant for advanced learners. This article is intended to enlighten the concept to the beginners in the field and further to improve knowledge about detailed steps for abstract mathematical formulation used which helps in understanding to derive TDSE using various tools and in more comprehensible manner. It is shown that TDSE may be derived using wave mechanics, time independent equation, classical & Hamilton-Jacobi’s equations. Similar attempts have been done earlier by some researchers. However, this article provides a comprehensive, lucid and well derived derivation, derived using various approaches, which would make this article unique. © 2015, AcademicDirect. All rights reserved.

The present article presents a systematic overview of the Nobel Prize winners over the last 115 years in Physics, particularly one of its branches - quantum mechanics, based on the data available over the same period. An attempt has been made to show the trend lines of the area of research in quantum mechanics in this period. Quarter-wise analysis of the prizewinners is also presented. Various factors such as beneficiary Universities, respective countries, and age factors of Nobel laureates are discussed. The results of statistical analysis are discussed in the light of the implications for novices, who have a keen interest to know more about the development of quantum theory. © 2015, Ivan Franko National University of Lviv.
