Abstract :

Cd2+ rich Cadmium Sulfide (CdS) nanoperticles caped with Triethanolamine (TEA) as an organic ligand were synthesized by chemical precipitation. These nanostructured CdS nanoparticles were deposited on aluminum foil by electrophoretic deposition technique. Both nanoparticles and thin film are studied by x-ray diffraction, glancing incidence x-ray diffraction and atomic force microscopy measurements to understand the growth, stability and surface morphology. The highest photocurrent obtained as 6.5 μA at incident wavelength λ = 400 nm with an applied bias voltage of 10 V in the CdS thin films. Also time response of the photocurrent reveals the corrosion at the surface of CdS particles i.e get decompose into Cd2+ and S2- ions.

Dozy-chaos end of the human civilization
VLADIMIR V. EGOROV (egorov@photonics.ru)
Russian Academy of Sciences, Photochemistry Center, 7a Novatorov Street, Moscow, 119421, Russian Federation
Abstract :

It is proposed to consider human beings and human community as very complex molecular physical systems in which dozy chaos plays a governing dynamic role. Dozy chaos is the cause of molecular quantum transitions and various chemical reactions, and as a result, the evolution of the entire molecular matter, up to the emergence of life, genome, and human being as such. It puts forward a concept of self-examination of dozy chaos, from which it is shown that mankind is likely doomed to failure in the short historical perspective as a result of the disastrous rise of egoistic inner contradictions, unless it learns to recode its genome from egoistic to altruistic by controlling dozy chaos on a global scale. It is argued that from the perspective of the survival of humanity in conditions of the existing egotistic human genotype, bipolar political arrangement of the world is preferable to both unipolar and multipolar arrangements of the world. It is shown that the gap between the high, and further growing rapidly, level of technological progress and an extremely low level of altruism of the human genotype, caused by our biological origin from the animal world, is the main and fatal source of our likely collective and common suicide in the near future.

General Fuzzy mathematical expression for carrier of a genetic disorder
VIJAYKUMAR N. JOSHI (vnjoshig@gmail.com)
Retired Prof. of Computer Science from University of Mumbai (India)
Abstract :

In this paper a general fuzzy mathematical model for any genetic disorder is proposed. A genetic disorder is caused in whole or in part by a change in the DNA sequence away from the normal sequence. A gene is associated with the disorder, e.g. FXN gene is associated with Friedreich’s Ataxia, PRKN with Parkinson’s disease, APOE with Alzheimer disease, HOXB with Breast and Prostate carcinoma etc.. We have attempted to present a carrier model of disorder based on fuzziness factor
