A new parameter is introduced in the structure of the phase term of the plane wave solution. This new parameter is satisfying a further symmetry in regard to famous conjugates of Heisenberg’s Uncertainty Principle, so the correlation between this parameter and angular momentum could provide new inspirations on the wave-particle duality, propagation dynamics of electromagnetic wave and possible connections between Quantum Mechanics and Electromagnetic Theory.

A technology to produce low alcoholic self carbonated beverage from carrot:amla juice is developed. The yeast culture Clavispora lusitaniae has the potential to produce less alcohol (< 1%) and high bar pressure (1.5 bar) of carbon dioxide in fruit juice during fermentation. CO2 produced adds tangy taste, body and sparkle to the beverage, additionally is effective against gram negative aerobic spoilage bacteria. Its fungistatic and bacteriostatic effect depends on the dissolution of gas in water phase of beverage. When crop is harvested, it often creates a glut-like situation, so to safeguard the interest of progressive horticulturists, the utilization of fruits for the production of low alcoholic self carbonated beverage is economical and an appropriate viable technology.

Laccase activities were found after GLC analysis of culture liquid of mycelium extract Ganoderma lucidum grown on malt extract medium with or without inducers. These laccase enzyme (E.C.1.10.3.2 paradiphenol: oxygen oxidoreductase) catalysis the oxidation and polymerization of aromatic compounds in the presence of molecular oxygen. Laccase activity in the malt extract medium had on pH 3–4 and was stable from pH 3–10 during 24 hr at room temperature. This enzyme had wide substrates specificity on hydroquinone, methoxy-substituted monophenols and aromatic amines. The laccase activity was found only with compounds having a redox potential lower than 0.5 mV. The highest activity was obtained with methoxy, methyl-substituted p-hydroquinone and aromatic diamines. Some activity also occurred with the aliphatic compounds 3, 5– cyclohexadiene-1, 2-diol.

Water is one of the abundantly available substances in nature. It is an essential ingredient of animal and plant life. Ground water is required for industrial processes. Pollution of land, water and air through water generated as result of increasing population, urbanization and industrialization is a challenge of serious dimensions. Pollution of natural water by industrial waste is objectionable and damaging for many varied reasons. Primary importance is the possible hazard of public health by the contamination of stream with disease producing Microorganisms. The disposal of textile wastewater without treatment is the most common practice in the country, which adversely affects the environment, resulting in serious environmental problems. Environmental pollution is caused predominantly by the industrial effluent disposal in water bodies. To screen and identify different cellulolytic fungal isolates and determine the degradation activity of cellulolytic fungal species. To determine the BOD and COD of the tannery effluent by cellulolytic fungi after various incubation periods. The bioremediation or treating the tannery effluents using various cellulolytic fungi Trichoderma, Pencillium, Aspergillus Sp.

For any abelian group A, a graph G is said to be A-cordial if there exists a labeling f : V(G)→A such that for every a,b ∈ A we have |va −vb| ≤ 1 and (2) |ea −eb| ≤ 1, where va and ea respectively denote the number of vertices and edges having particular label a. In the present work we investigate a necessary condition for an Eulerian graph to be V4-cordial. In addition to this we show that all trees except P4 and P5 are V4-cordial and the cycle Cn is V4-cordial if and only if n # 4 or 5 or n # 2(mod 4).

Let G be a graph with vertex set V(G) , edge set E(G). For each vertex (or edge) of G, a new vertex is taken and the resulting set of vertices is denoted by V1(G) (or E1(G)) respectively. Let G and L(G) denote the complement graph and line graph of G. The middle graph M(G) as an intersection graph ...
