Republic of Kazakhstan oil will last for 47.4 years, while gas production - 65.6 years. Given the Kashagan reserves, something else for a longer period, that is a very short periods of time with respect to the development of state and they can be extended only by the development of a technological breakthrough. Along with the question of the ever-growing needs of the population for energy resources, there is a question about the availability of annual waste generation as the impact of the rapid growth of the urban population, which is about 4% per year ("Population" encyclopedia of Astana, 2008). To cope with both problems simultaneously, the waste may be used as energy sources by fermentation technology. Among the urban wastes the organic waste is dominated, such as vegetables, fallen leaves, etc., that have the potential to produce biogas. The use of unsuitable materials as a natural catalyst of fermentation and the time spent on fermentation, are some of the existing barriers to the development of energy resources in urban areas. For this purpose a study was conducted to optimize the ratio of urban waste, animal waste and water in combination with the time of fermentation. The study used an experimental method with the random nature of the two-factor model. The first factor is the ratio of waste, manure, and the second quantity of water - during fermentation, which is fixed to each of 2, 4, 6, 8, 10, 12, 14, 16 and 18th day of the fermentation substrate. The study showed that the optimum proportion to obtain the maximum amount of biogas is a ratio of 500: 200: 300 waste, manure, and water, respectively. Furthermore, on the second day of fermentation the maximum amount of biogas produced.

This research is determining the impact of adding natural dyes turmeric and Sabouraud Dextrose Broth (SDB) against physicochemical of tempeh. Benefits of the research is to support the food security program through increased value-added tempeh using natural dyes. This research was conducted by the method of experimental design was completely randomized. The first treatment is concentration of turmeric (K) and the second is the concentration of SDB. The first consists of three concentration levels (0.5% , 1% and 1.5%), and the second also consists of three concentration levels (1% , 2% and 3% ) and repeated 3 times. The test results chemically the protein , fat and ash contents between the tenth treatment showed not significant (P> 0.05), the test results of water content between the ten treatments of at least two show difference (P <0.05), also carbohydrate (P <0:01).Keywords: physicochemical, colored tempeh, turmeric, natural dyes, SDB

The Impact

This paper aims to investigate the feasibility offlood management based onthe concept of Integrated Watershed Management (IWM) via a literature review and field surveys. The investigationfocused on the primary industry of oil palm plantations in Malaysia. Although the country is promoting the palm oil industry, the impact of oil palm plantations on the local environment has been relatively disregarded because of the benefits and opportunities, such as subsidies, jobs, and amenities,which the local companies/people can obtain. Effective flood management inoil palm plantations entails the local peoples’ understanding and participation in the management activities, such as removing fallen leaves and weeding an area. Theflood management strategiessuggested inthis research provide new insights into local flood management, which usually focuses on the hydrologic aspects, by promoting the integration of the actual-local environment and local people’s actions for their environment within the framework of IWM.

In the past few years, deciduous landscape conservation has become a trend in China; however, the theoretical support is still limited, and the impact of demographic characteristics on people’s attitude toward deciduous landscape still needs to be explained. This study aimed at exploring the differences among demographic groups through Likert scale questionnaires of 981 respondents. The results show that of all characteristics, only age has a significant influence on deciduous landscape preference. However, there is a paradox for elderly people: they have the highest preference for deciduous landscape and the lowest intention to keep deciduous landscape in their lives at the same time. Moreover, the elderly tend to care about the underlying surface of deciduous landscape while the reliable predictor for other age groups is the color of fallen leaves. These findings can be useful for practical applications, which might guide future development of deciduous landscape planning and maintenance.

The Impact

Mangroves generally grow in nutrient-poor environments and maintain high levels of productivity through unique adaptations for nutrient conservation (Reef et al. 2010). One such adaptation in mangroves is highly efficient resorption of limiting nutrients from senescing leaves prior to abscission (Feller et al. 2003). Thus processes that lead to loss of foliage prior to senescence and nutrient resorption (e.g. storms and herbivory) can be detrimental to tree growth and productivity (Bryant et al. 1983, May & Killingbeck 1992). Furthermore, decomposition of fallen leaves by soil microbial communities (Alongi 1994, Holguin et al. 2001) and crabs (Nagelkerken et al. 2008) is another important process contributing to the recycling of nutrients that are in short supply. Therefore, processes that lead to a substantial reduction in litterfall can have a strong negative effect on nutrient cycling and forest productivity. Mangroves have long been recognized as an important source of organic carbon (both particulate and dissolved) for the surrounding tropical coastal ecosystems (Bouillon et al. 2008, Kristensen et al. 2008). Thus, processes affecting litterfall in mangroves can affect the surrounding marine food webs.

The Impact

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.
