Nowadays, more research effort is put on energy efficiency issues. Researcher has been doing research to find more energy-efficient lamps. Australia and Europe tried to eliminate the use of incandescent lamps in 200 while China targets complete replacement in 2016
Relationships between organic matter and carbon contents of organic wastes
free download
The increasing produc- tion of organic wastes and their recycling and use in agriculture, either as amendments or as soil fertilizers, has led to the need for finding analytical methods, similar to those employed for soil, for the determina- tion of their organicmatter content
Organic matter and enzyme activity in particle-size fractions of soils obtained after low-energy sonication

Construction of Chemistry Teaching Material Using Organic LED (OLED) Context for High School Students
free download
Science education should really be able to project students not only to obtain knowledge, but also to apply those knowledge. This is triggered by the establishment of the AEC, which challenges Indonesian resources to compete with foreign resources. In addition, young
Parsing of Data Led to Mixed Messages on Organic Foods Value
free download
A team of scientists laboriously reviewed decades of research comparing organic fruits and vegetables with those grown the usual way. They found that, as many had suspected, the organic produce, farmed without synthetic fertilizers or pesticides, was more nutritious, with
Introduction to organic chemistry
free download
Increased knowledge has led to recentimprovements in these ancient procedures Baker (1967), for example, has published a book dedicated to the organic chemistry of the active site (of enzymes), and Hirs (1967) has edited a detailed compilation of laboratory procedures for

On the reactivity of carbonic and organic acids and generation of secondary porosity
free download
This has led to an interest in organic acids as a means of creating secondary porosity in sandstones through dissolution of carbonate and aluminosilicate minerals. This paper compares stoichiometric and thermodynamic reactivities of organic acids to those of carbonic acid
Organic removal and microbiological features of UASB-reactor under various organic loading rates

of a laboratory upflow anaerobic sludge blanket reactor (UASB-reactor) fed synthetic wastewater was investigated under organic loading rates (OLRs of the granules showed that the predominant microbial bio- mass was Methanothrix Howeve increasing the OLR led to a This behaviour, indicative of the rapid oxidation of at least some of the organic material in sea water, led us further to examine the laboratory applications of high intensity ultra-violet radiation to analytical and other problems associated with the presence of dissolved organic
Organic ion transport during seven decades the amino acids
free download
My title is intended to suggest that the dynamic subject of ion transport had an earlier beginning as organic ion transport than as inorganic ion transport. Furthermore, an unfortunate poverty in analogs for the usual inorganic ions has led to extra difficulties in differentiating their
Benefits of organic farming for society
free download
Abstract Recent food scares have led to a boom in demand for organic products and have increased policy makers awareness of the potential benefits of organic farming. However, policies specifically targeting organic farming
Ternary organic solar cells offer 14% power conversion efficiency

4 led to Rrms reduction, suggesting that fullerene could help the mixing of PTB7-Th and COi8DFIC enhancing Jsc and FF significantly. In summary, a high-performance active layer for organic solar cells was developed by adding PC71BM into PTB7-Th:COi8DFIC blend
Enzymes in organic solvents

The altered selectivity of proteinases in organic solvents has led to the catalysis of pcptidc synthesis with D-amino acids The rigidity of proteins in anhydrous organic solvents has led to the discovery of an enzyme memory phenomena 141
Investigation of the thermal and biological stability of soil organic matter

led to an integration of evolutionary biology and soil science and, conse- quently, to new approaches to the understanding of very complex, long-term, geologi- cal, developmental processes in the biosphere. Thus, an attempt was made to describe the behaviour of soil organic
Organic regulation of phytoplankton fertility
