Abstract:Daruparpatadi decoction has been used extensively in Sri-Lanka for treatment of a number of respiratory tract ailments. No studies have examined the bioactive compounds present in this decoction. the aim of the study was to assess and compare the phytochemicals present in the hot aqueous, hexane, ethyl acetate and ethanol extracts of the Decoction of the Daruparpatadi. Hot aqueous, hexane, ethyl acetate and ethanol extracts of the Decoction of the Daruparpatadi were prepared and all the preliminary phytochemical test were done with standard methods. A wide variety of pharmacologically active phytochemical compounds such as higher amount of tannins and phenolic compounds, terpenoids and steroids, flavonoids, cardiac glycosides, carbohydrates, amino acids, anthaquinone glycosides and resins were found in this hot aqueous and ethanol extract of the Daruparpatadi. Alkaloids found higher in the ethanol extract. Saponins were less in all four extracts comparing with the other phytochemicals. The qualitative phyto-compounds of this decoction confirm the use for various ailments such as asthma, phlegmatic fever, colds and tuberculosis by the practitioners. Further, the quantitative analysis of these phyto-compounds will be an interesting area for further study to exploit the other biomedical applications.

Title: Stochastic Multi-choice Bi-level Programming Problems using KKT Approach

Abstract:In the present paper, we have developed a new methodology and solution procedure for solving stochastic multi-choice bi-level programming problems taking the right hand side parameters of the constraints in both first level and second level as multi-choice parameters but constraints and objective function coefficients in both leaders and followers as exponential random variables with known means. In order to solve the proposed model, equivalent deterministic non-linear bi-level programming models are established by using binary variable transformation technique. Then the models are solved by using KKT approach and obtained the optimal solution. A numerical example is constituted to illustrate the utility of the proposed methodology and solution procedure.

Title: Study on Influence of Dietary Factors on the Excess Weight Gain in Adult Females

Abstract:Obesity is a global problem all over the world and the health problems associated with obesity are numerous. Dietary factors are the major modifiable factors by which many of the external influencing factors for the excess weight gain can be minimized. The aim of the study is to explore the dietary factors which influence on the excess weight gain in females. A cross-sectional study was conducted at the National Ayurveda Teaching Hospital, Borella. Data were collected from 247 female participants in a pre-structured questionnaire by interviewing subjects through face to face interview. ANOVA and multiple regression models were used to analyze and predict factors which influence to the obesity. “Dietary amount” variable showed a significant positive relationship with the BMI at the level p < 0.01. This depicts that the amount of food consumed is directly proportional to the BMI. Further, in the present study, excess eating habits and excess consumption of non-vegetarian diet were shown as significant influencing factors to obesity. Also excess consumption of “samba” rice and excess usage of oil were also considered as influencing factors to obesity. Further, another noteworthy observation is that most of the “Kekulu” and “Nadu” rice consumers were overweight, but not obese. When compared to the correlation between additional eating and obesity, the correlation between banana eating and obesity is negligible. Study concluded that implementation and encouragement for healthy eating habits and appropriate intervention to promote physical activity to diminish the increasing percentages of the obesity in the society.

Title: Nutritive values, Phytochemical constituents and Bio-activities of Carica papaya seeds which are discarded as waste of the fruits: Systematic review

Abstract:It has been in practice to discard the seeds of the most fruits such as papaya , tamarind, etc as waste . In contrast, scientific study shows that the seeds of the fruits are having valuable nutritive values and various bioactivities. Objective of this systemetic review was to scritinize the research articles on the nutrititive values and the bio-activities of the seeds of Carica papaya (CP) to exhibit the scientific evidence. Google scholar was used to filter data. A total 50 articles were identified and 32 articles and 2 authentic text were analysed. The review revealed the seeds of the CP have multifunctional bioactivities such as anti-inflammatory, anti-fungal, and anti-cancer in addition to hepato-nephro protective activities etc. The review further exhibits that seeds also contain nutritive properties such as sucrose, protein, fat, calcium, phosporous etc which are essential for the body. Further, the CP seeds have many chemicals such as carpain,benzylisothiocynate, benzylglucosinolate etc. Therefore, consuming the seeds of the CP would provide nutritive value and also act as a medicinal diet in preventing the disease conditions. Based these facts it is proposed to scientifically scrutinize the seeds of the CP further to unearthen the precise nutritional and bio activities of the seeds in human being and to produce and market the CP seeds as a supplement.

Title: Exploring Competence of Albizia lebbeck fruit pod, a low-cost biosorbent for removal of Heavy metal ions like Cu(II) and Ni(II) from an aqueous phase

Abstract:Albizia lebbeck fruit pod (ALFP) was used for the Biosorption of Cu(II) and Ni(II) ions in a batch adsorption set up. The sorption capacity was ALFP was investigated as a function of adsorbent dose, initial metal ion concentration, pH, temperature, agitation time and shaking speed. The adsorption efficiency of metal ion uptake with ALFP increases with adsorbent concentration, temperature and agitation time, decreases with increase in metal ion concentration and shows initial rise followed by a decline with pH and shaking speed. The sorption process was very fast and equilibrium was achieved in 40 min.Equilibrium data fitted well to Freundlich isotherms model. Batch adsorption models, based on assumption of first-order, pseudo-second order, Elovich equation and Weber and Morris intra-particle diffusion model were utilized to identify the rate and kinetics of sorption of copper and nickel onto ALFP. Pseudo-second order model was found to best fit the kinetic data. FTIR and SEM were used to study the surface characteristics of ALFP. Thermodynamic parameters such as〖 ∆H〗^0, 〖∆S〗^0 and 〖∆G〗^0 were calculated describing adsorption process to be endothermic and spontaneous. The study supported the use of ALFP as a cheap, effective and eco-friendly alternative for the treatment of Cu(II) and Ni(II) containing.

Title: Phosphate-accumulating potential of bioflocculant-producing microorganisms of the aquatic ecosystems in Arctic Region

Abstract:The aquatic ecosystems of the Arctic part of the Russian shelf, including bodies of fresh water, are characterized by unique geophysical conditions that determine the extreme properties of the environment. The hydroecosystems of the Arctic region, which are vulnerable by their nature, as well as the aquatic ecosystems of other geographical zones, are equally exposed to anthropogenic pollution, but in their case it is much more difficult to cope with pollution means. Improvement of the state of water bodies, including those used for trout breeding, as well as increase of their regenerative potentials is possible only through optimization of biochemical processes of transformation of pollutants. The processes of self-purification of natural water bodies are caused by numerous physical, chemical and mechanical factors, but are carried out by aquatic biota, primarily organotrophic bacteria. It is microorganisms that consume substances that are pollution for other hydrobionts in the course of their life [1]. It is obvious that organisms living in extreme conditions of the Arctic region have formed adaptations to them and can have unique properties, and, consequently, a great biotechnological potential. The study of the role of indigenous microorganisms in reducing the level of anthropogenic pressure on the Arctic ecosystems is very relevant. In this work the phosphate-accumulating ability of microorganisms� groups that synthesize bioflocculant is estimated. The influence of several different factors on the processes of phosphate accumulation is researched via modelling of the cultivation conditions. In the experiment, microorganisms with flocculating activity of more than 60 %, belonging to the bacteria of the Pseudomonas and Aeromonas genera, previously obtained from various aquatic ecosystems, were used. The growth rates of each culture on the media of different composition varied within 2-3 orders of magnitude and correlated with the relative phosphorus content in the medium. The formation of floccules in non-replaceable nutrient media with phosphorus content from 120 to 980 mg/l occurred in the period from 5 to 10 days of cultivation. The rate of flakes formation did not depend on the concentration of phosphorus in the medium. The ability of microbial cultures to mobilize different forms of phosphorus, along with the bioflocculant-producing activity, was influenced by the concentration load and the duration of cultivation of the strains.

Title: Behavior of Neutrons and Gamma Radiation During Penetration in some Shielding Materials

Abstract:Radiation measurements with mixed field from neutrons and gamma radiation are complicated. In the recent work, two types of neutron sources (252Cf and Pu-α-Be) have been used. The neutron spectra of these sources have been traced using neutron/gamma spectrometer with stilbene scintillator. This spectrometer could discriminate between pulses produced by recoil proton and those produced by recoil electron using a double different method. Measurements were performed to study the dependency of slow neutron and gamma in polypropylene and steel on the spectrum shape of the radiation penetration. A BF3 and TLD-600 detectors measured the slow neutron flounce and TL-Intensity, while TLD-700 detectors measured the gamma TL-Intensity. The slow neutron flounce and total TL-Intensity for neutrons and gamma were measured behind different thicknesses of the investigated materials. The measuring values gave the form of distribution relations, which indicates the dependency of dose value on the incident field and the atomic weight of the penetrated material.
