  • Cell walls of microalgae consist of a polysaccharide and glycoprotein matrix providing the cells with a formidable defense against its environment. Anaerobic digestion (AD) of microalgae is primarily inhibited by the chemical composition of their cell walls containing biopolymers able to resist bacterial degradation. Adoption of pre-treatments such as thermal, thermal hydrolysis, ultrasound and enzymatic hydrolysis have the potential to remove these inhibitory compounds and enhance biogas yields by degrading the cell wall, and releasing the intracellular algogenic organic matter (AOM). This paper preproposal stage investigated the effect of different pre-treatments on microalgae cell wall, and their impact on the quantity of soluble biomass released in the media and thus on the digestion process yields. This Paper present optimum approach to degradation of the cell wall by ultra-sonication with practical design specification parameter for ultrasound based pretreatment system. As a result of this paper presents, a microalgae system in a wastewater treatment flowsheet for residual nutrient uptake can be justified by processing the waste biomass for energy recovery. As a conclusion on this result, Low energy harvesting technologies and pre-treatment of the algal biomass are required to improve the overall energy balance of this integrated system.

  • Remote sensing and measurement are of paramount importance of providing information on the state of water quality in water bodies. The formation and growth of cyanobacteria is of serious concern to in land aquatic life forms and human life. The main cause of water quality deterioration stems from anthropogenic induced eutrophication. The goal of this research to quantify and determine the spatial distribution of cyanobacteria concentration in the water using remote sensing technique. The standard approach to measure water quality based on the direct measurement of the fluorescence of the chlorophyll a in the living algal cells and the same approach used to detect the phycobilin pigments found in blue-green algae (a.k.a. cyanobacteria), phycocyanin and phycoerythrin. This paper propose the emerging sensor design to measure the water quality based on the optical analysis by fluorescence of the phycocyanin pigment. In this research, we developed an method to sense and quantify to derive phycocyanin intensity index for estimating cyanobacteria concentrations. The development of the index was based on the reflectance difference between visible light band 620nm and 665nm. As a result of research this paper presents, an optical biological sensor design information to measure the Phycocyanin parameters in water content.

  • This study has been performed to explore conveniences and inconveniences of daily lives in rural residential care facilities among the elderly residents. In this study, five males and seven females aged 68 to 78 were asked about socio-familial and physical aspects of their daily lives in the facilities such as meals, social activities, family visits, recreation, and health care. The answers of the qualitative interview were drawn as follow; first, the residents perceived well planned regular meals and snacks, free visits of friends, regularly supervised daily sanitary activities, periodic outdoor activities, education programs provided by religious experts, and pastoral farming lives as most convenient aspects of the retirement facilities. In addition, some felt that facility life made them free of familial conflicts, while others appealed fear of being forgotten because of distant location. On the other hand, they perceived the supervised group activities and meals as major inconveniences. They also felt persistently depressed when closely observing serious illness or deaths of their co-residents. Therefore in this study, suggestions were made as follows: first, combination of normal family life and retirement facility should be developed in the mixed form of community welfare center and shared home. Second, intensive medical care facilities should be in collaboration with the retirement facilities, so that the residents are relieved from stressful contacts with extremely ill patients in the residential area.

  • The Maasai community from Kenya is highly esteemed for their strong adherence to traditional cultures and ethno medicine. This is attributed to their age-old traditional mechanisms of passing down knowledge to the younger generation. Adoption to new socio-economic lifestyle and urbanization has been associated with development of diabetes, which has been reported among some indigenous pastoral communities in Kenya. Documentation of traditional methods of treatment and management of diabetes by the Maasai has not yet been reported, yet it is noteworthy. Thirty traditional healers from Narok County were purposively selected and interviewed about traditional knowledge of antidiabetic medicinal plants, parts used, preparation dosage and administration. A total of 14 antidiabetic plant species distributed within 13 genera and 12 families were identified and documented as herbal medicine used in the management of diabetes. The most highly cited plant species was Dovyalis abyssinica (20%), the plant family Flacourtiaceae and Rhamnaceae (2 plant species each) recorded the highest number of plant species while the most frequently used plant part was the roots (46%). Literature review revealed that some of the cited plants have known phytochemicals with antidiabetic activity; the study recommends further scientific investigation to validate their efficacy and safety.

  • Weaner heifers were set stocked at 4/ha on a grass-legume pasture in South Sulawesi, Indonesia, and either unsupplemented (Control) or for 338 days given daily supplements of one of, rice bran (RB) supplied at 1 kg/animal/d, molasses/urea (MU) or 0.5 RB + 0.5 MU (MURB) the amounts of which were adjusted to give similar energy intakes. There were 20 animals in each treatment. A drought resulted in low pasture availability for about half the supplementation period. The LWG per animal in the MURB treatment was 85 kg above that of the control and this was significantly greater (p < 0.01) than those for MU (62.0 kg) or RB (56.2 kg) although the economics favoured the gains from RB which returned over three times the cost of the supplement. Costs could be reduced by supplementing only at times of maximum undernutrition, but such a strategy is of doubtful value in this situation as there was no compensatory LWG and a similar rate of economic return was maintained throughout the period. The results suggest that additional benefits from the supplementation may be improved reproductive performance and more efficient use of pasture.

  • The hand printed cottons of India are historically world-renowned for their rich fast colours, elaborate designs, and matchless quality. Until the discovery of synthetic dyestuffs in the latter part of the nineteenth century, the unsurpassed master dyers of cotton were the craftsmen of India-birthplace of cultivated cotton. The Indian printers and dyers monopolised this arcane art of permeating cotton cloth with richly hued, colour-fast designs, and the fruits of their labour proved hugely influential in international trade and the development of modern textile technologies. This paper focuses on a lesser-known body of hand printed cottons, traditionally produced in rural Rajasthan for everyday use by the local pastoral communities. Drawing on extensive research carried out with the region's Chhipa community of hereditary cloth printers, the complex and multiple applications of mordant, dye and resist are illustrated. Often taking months to complete, the enduring popularity of these labour-intensive hand printed cottons is then discussed, particularly in the light of the hugesocial importance borne by cloth in Rajasthan. Cloth and clothing are widely recognised as indicators of social status, gender, rank, and individual and group affiliations. In addition, cloth and clothing have been established as indicators of social, economic, political and technological change. The paper concludes by drawing attention to the recent influx of machine-printed polyester textiles, often replicating the designs or colours of the traditional locally produced cottons. Thus women of the region, whilst using these modern synthetic textiles as part of newer ways of expressing their identity, also visibly retain the values associated with hand printed cottons and traditional dress codes.

  • Using modified Lincoln solution, hydroponic system was developed to compare simultaneously a range of pasture species in terms of relative growth rate(RGR), rate of roots to shoots, and relative root volume and root area. Modified Lincoln solution achieved optimum growth of nineteen forage species tested, and was proved to be a good method for studying plant root characteristics. RGR was measured sucesshlly showing reasonably consistant values over time. There was a much differences in rootkhoot ratio between species within groups as between groups. Root tissue density was lower in grasses than legume or herb group. Root area index was very high for grasses and herbs, and this index should be useful for evaluating the comparative root system of different species.

  • This examination was conducted as follows; 189 copies were coated in total, and demonstratively analyzed by SPSS WIN 15.0 program. The methods used in data for this analysis are as follows; Sensitivity, Reliability, Frequency, Internal consistency, One way ANOVA(Scheffe's examination) Analysis, T-test, etc. The findings of this study are as follows; firstly, it was revealed that respondents who were regular customers of Italian restaurants regarded convenient transportation, property of space, property of pastoral, visibility, and accessibility as importance. This means that Italian restaurant marketers should consider some of factors of location for business with a good view, good parking lot, location at main street, smooth flow of traffic, luxury, atmosphere of freedom, clean area around restaurants, elegant interior of the building, comfortable, luxurious, and deluxe atmosphere, and so on. Secondly, it was revealed that respondents who were regular customers of buffet restaurant either considered the same factors as the Italian restaurants above or regarded those factors less important. This suggests that restaurants should be located on main streets, on trunk roads, and in large-scale residential districts of apartment complex. Thirdly, it was revealed that respondents who were regular customers of traditional restaurants did not consider the locational factors above. This shows that traditional restaurants should be located in nearby customers' houses or their working places, and that marketers should consider focusing on their restaurants' homelike atmosphere, cleanliness, food flavors, and so on.

  • The government has made a great effort for the development of rural area. The aim of this study is to analyze the change process and characteristics of the government's rural area development policies implemented so far and present an aid as adequate material to the direction of development policy for rural areas. The rural area development policy had been focused on maintenance of physical infrastructure facilities in the rural areas, pursuing urban convenience led by the government from the 1950s to 1990s. The policy has changed to local residents-led rural area development from the late 1990s to present time. The basic direction of the policy turned into making much of environment-friendliness and promotion of regional activation. The policy was transformed to recognize our rural area and also perceive it pastoral and resting space. In addition, green tourism has emerged as an important theme since 2000. In the rural area development policy, it is the most important to connect it with various development projects, select target areas from the long-term perspective and pursue efficiency through intensified investment of financial resources.
