Opis:
The velocity of the solar system around the galaxy as it moves through universal dynamic pressure of about 0.15 nPa results in a critical mass density of 1.5 protons per cc. Interplanetary measurements indicate this density occurs within the space occupied by asteroids. Quantitative evidence is offered that the matter in asteroid space failed to accrete into a planet because of the disruptive resonance between universal dynamic pressure and the velocity of the system. The model may accommodate the chemical characteristics of the different regions of the asteroid belt and the marked difference in planetary characteristics above (the inner planets) and below (the “gas giants”) the critical density. The energy accumulated within the functional toroidal space between Mars and Jupiter since the formation of the solar system is equivalent to the total mass of asteroids. If energy is still emerging within this region then the probability of non-traditional disruption of orbits for certain masses of asteroids may have significant impact. Specific frequencies that should show enhanced power based upon these calculations are derived.

Opis:
A fashion trend is emerging in Islamic culture based on the concept of modest fashion all over the world. Significant brands of the Western fashion world have already launched their Hijab and Abaya lines. The objective of the present research is to investigate the important factors of modest fashion in the Islamic culture and to detect the future world fashion trends of Islamic fashion and then to appliance the concept of modesty to the fashion market of Sri Lanka. This investigative study is based on the qualitative and questionnaire-based methods. The study is confined to questionnaires which were distributed among a sample of 150 Muslim women with diverse backgrounds to gather data and statistics around Colombo and Kandy. Secondary data were collected from books, articles, web sites and visual data such as pictures and photographs which facilitated to forward a successful research. Examination of the influence of culture on Muslim women’s dress etiquettes led to understand what Muslim women expect from their dress and led to identify potential opportunities in the contemporary market of modest fashion.

Opis:
Biosphere Reserves all over the world are areas that are deliberately and purposely kept to promote green economy and most importantly mitigate the effect of Global warming and climate change. The problems of climate change arise from the higher concentration of greenhouse gases in the atmosphere which exert a warming effect on the earth. Control of anthropogenic sources and greenhouse gases are constantly discussed and extensively researched in this matter, while the significance of microorganisms remained neglected. Although microorganisms has a contributory effect in global warming as in the case of methanogenes in the rumen of ruminants which has been implicated to increase the environmental methane gases during digestion, the role they play in converting greenhouse gas to useable form in the soil and water hence, reducing global warming cannot be over emphasized. The current review aimed to stress the neglected global importance of microorganisms in climate change. Overall, this review further support the key role biosphere reserves play in protecting soil and plant microorganisms in response to climate change control.

Opis:
Finger millet is a staple food crop of many communities in Africa. The crop is highly nutritious and has incredible grain storage quality. Limited research investment in finger millet in the past has resulted in poor yields and there are currently no commercial hybrids. We investigated the response of different finger millet genotypes (Okhale-1, Gulu-E, KACCIMMI-72, IE 2872, IE 4115 and U-15) to the application of a plant growth regulator hormone (Ethrel). Six elite Kenyan finger millet varieties with contrasting agronomic traits were crossed in a 6 x 6 diallel pattern. To enhance male sterility across female parents, we subjected the plants to Ethrel at concentrations of 1,500ppm, 1,750ppm and 2,000ppm against a 0ppm check. Dwarfing of sprayed plants that resulted in less lodging and ultimately higher yields were observed among plants sprayed with Ethrel at different concentrations. Ethrel application at 2,000ppm had the most dwarfing effect on plants while spraying plants with 1,500ppm of Ethrel resulted in increased grain weight. Although our results demonstrate overall positive effect of Ethrel on finger millet production, the optimum concentrations for more efficient hybridization will still need to be determined.

Opis:
New theoretical and traditional quantitative solutions involving a pervasive unit quantum of ~10-20 J within biological and large-scale physical systems predicted that the mass of the human subject, subtle changes in gravitational phenomena, and the energy available within the cerebral volume should affect proximal random number variations produced by electron tunneling. In a series of experiments application of a specific, physiologically-patterned weak magnetic field over the right temporal lobe significantly enhanced the effects of intention upon deviations from random variations created by electron tunneling devices at a distance of 1 m. These variations were strongly (r ~0.80) correlated with the coupling between the forces from the background free oscillations of the earth and the energy differences across the cell width between lunar perigee and apogee. The results support the approach that complex cognitive processes including “intention” can be described by physicochemical parameters and their magnitude of energies are within the range by which interactions or modulations from subtle gravitational forces applied across the cellular membrane and width might occur.

El-Oued is known for some diseases caused by fluoride concentration in drinkable water. To reduce it, we have chosen a sample with the highest content of fluoride among many sources in order to coagulate it with Al2(SO4)3ź18H2O, Fe2(SO4)3źH2O and FeSO4. In order to get better reduction yield of fluoride, a study has been done on the influencing parameters (concentration, pH, temperature) to choose the best conditions. The remove of fluoride is favorable at low concentration of Al2(SO4)3, at room temperature and normal acidity.

Opis:
Terminalia chebula, a plant rich with phytochemicals, was selected in the present investigation for evaluating its immunomodulatory activities. Extract of the leaves were prepared in various solvents. Ethanolic extract was found to contain significant amount of phytochemicals. Hence, it was selected to study immunomodualtory activity. Silica gel column chromatography of ethanolic extract was performed. The fractions were further subjected to TLC and most active fractions were administrated to balb/C mice for evaluating immunomodulatory studies. Out of the five fraction (S1 – S5), S3 was found to possess immunostimulant activity. Provision of Ethanol Extracts of Terminalia chebula on balb/C mice can increase the antibody titers IgM and IgG.

Opis:
The human microbiome is a complex collection of microorganisms, including their genes and the metabolites colonizing the human body, and playing various functions in health and disease. The arrival of culture-independent molecular techniques such as metagenomics, transcriptomics, proteomics, and metabolomics have removed the limitations imposed by culture-dependent techniques. These advanced techniques have also brought about some paradigm shifts in what is known about the structural and functional diversities of the human microbiome in health and disease. The dynamics of the human microbiome is implicated in a number of human gastrointestinal and non-gastrointestinal diseases. This makes it a contemporary issue in biological and medical sciences. Of interest, some applications have already emerged for the human microbiome. These include being the source of antimicrobial substances, faecal microbiome therapy, probiotics, prebiotics and phage therapy. Given that a number of factors can alter the host microbiome - such as environment, lifestyle, stage of life, occupation, mode of delivery, therapy and so on, there is a need for more human microbiome projects that will help to capture these diversities in various continents. Furthermore, for the full impact of the various applications (both potentials and current) of human microbiome to be felt, there is need for more studies that will fully elucidate their physiology in humans.

This discusses the prospects for understanding the genetic basis of few selected traits in humans. Phylogenetic analysis provides a path to identify genes and biological processes underlying any trait influenced by inheritance. We suggest that different experimental approaches should be undertaken for traits caused by common genetic variants versus those arising from rare genetic variants. We discuss the intellectual foundations of genetic of Mendelian traits in humans by examining the degree of freedom of four particular factors , namely toung rolling (1.307), hitchhiker’s tumb (3.22), widow’s peak (44.825) and mid digital hair (92.825).
