The study aimed to investigate the efficacy of group logo therapy in the perceived stress and psychological well-being in MS patients. Methods, semi-experimental pretest-posttest design study with a control group. Research community, all members of the "MS Society Kermanshah" Bvd.bh that MS had to select a sample size of 24 patients voluntary sampling method chosen, then matched the experimental and control groups (each group, 12) were replaced. The experimental group participated in 8 sessions of two hours of group counseling Logo therapy while the control group received none. Assessment, psychological scale riffs and Cohen's Perceived Stress Scale. Results showed increased levels of psychological well-being and perceived stress was reduced. The results of this study suggest that to improve the psychological status of patients with MS Logo therapy more attention be paid to the group meetings

Ecosystems are the basis of life itself! Ecosystems are frequently disturbed by natural factors and humans actions leading to the degradation of land and also lead to the extinction of species of plants and animals called “Keystone” species. Extinction occurs due to changes in landuse. This paper proposes a conceptual model that integrates physical and ecological aspects with human aspects of land degradation through multidisplinary approach. The study area is located in central Aravalli in state of Rajasthan. The climate on the whole is semi arid. This study examines the nature, spatial pattern, degree and causes of land degradation in central Aravalli hilly tract, which has ultimately disturbed and affected the ecology of the area. Here, degradation of forest resources, scarcity of water resources, decreasing underground water level, and decrease in arable land has put an immense pressure on the ecosystem. Main objectives are to analyze the factors responsible for ecological imbalances enforced through land degradation in the area, to diagnose the spatial distributional pattern of flora and fauna at different level and last to suggest action plan the ecological balance in the study area. Further, the sustainable development has been putforth, which is the development without destruction and deterioration of natural resources. Socio-economic development also must be sustainable both ecologically and economically and should be pursued without jeopardizing natural resources quality and availability for future generations. There is a need to harmonize development activities with integrated ecological management.

Thiaminase (EC 2.5.1.2) catalyzes the displacement of the thiazole moiety of thiamine (vitamin B1) by a wide variety of nucleophiles. The presence of thiaminase in the diet has been associated with the occurrence of thiamine deficiency symptoms among mammals, including humans and fish. Here, we reported the properties of thiaminase in the hepatopancreas of fresh water prawn (Machrobrachium rosenbregii) from Asejire Lake in Southwestern Nigeria. The enzyme was partially purified with ammonium sulphate precipitation and affinity chromatography. The specific activity of the thiaminase was 0.2 µmol/min/mg of protein. The Michealis-Menton (Km) constant was 0.5 mM as compared to 1 mM of aniline. The optimum pH was 5.0, while the optimum temperature was 500C. Reduced glutathione (GSH), 2 – mercapto ethanol (MCPE), Ethylene diamine tetra acetic acid (EDTA) and ascorbate significantly inhibited the enzyme but citrate showed activation of the enzyme activity at 97%. The amino acids: serine, lysine, valine, cysteine, proline, and aspartate also showed significant inhibition. The cations: Ca2+, Mg2+ Mn2+ and Sn+ showed complete inhibition on the enzyme. Hg2+, showed a slight inhibition on the enzyme. The thiaminase activity was significantly enhanced by Ni2+ while Zn2+ had no activity on the enzyme

The rapid growth of population leads to generation of waste especially in developing countries. Various strategies and procedures have been employed towards waste minimization but public behaviors remain unchanged. Recycling of food waste is one of practical solution to minimize waste at source since recycling is the highest level of waste management hierarchy, thus more preferable option rather than landfilling. This paper presents the potential of food waste composting at source using Biosense Scheme. The scheme introduced E-learning and Green Ambassador as the main tools of education for public towards waste minimization. The concept of fun learning features such as animation story, video presentation, pictures and testimonies triggers people to practice food waste composting. Green Ambassador as a role model inspired people to learn and understand the important of composting as part of conserving the environment. This paper describes the response of community in Seremban, Malaysia towards Biosense Scheme in promoting food waste composting. A survey for questionnaire analysis has been carried out to 231 respondents consist of students from primary and secondary schools, teachers, government staff, private staff and non-government organization (NGO) staff in Seremban. The survey activity supported by Heritage Biotech (M) SdnBhd, Seremban Municipal and Solid Waste Management and Public Cleansing Corporation, Malaysia. The significant factors such as demographic profile, knowledge and intention to practice composting were determined, as indicators of respondent’s attitudes towards waste management in Seremban Municipal Territory
