feasibility of methanolic wastes treatment containing chlorophenol in experimental uasb reactors i.e. r-i and r-ii working side by side constantly for a couple of almost 32 weeks were studied. uasb reactor r-i was initiated by utilizing the digested sludge alone, whereas, the uasb reactor r-ii was startedup by adding an activated carbon of an effective size 1.5-2.5mm to the digested sludge with...

the present experiment was carried out to determine the digestion kinetics of carbohydrate fractions of citrus by-products. grapefruit pulp (gp), lemon pulp (le), lime pulp (li) and orange pulp (op) were the test feed. digestion kinetic of whole citrus by-products and neutral detergent fiber (ndf) fraction and acid detergent fiber (adf) fractions of citrus by-products were measured using the in...

background : the most frequent use of diatoms in forensic science is the diagnosis of death due to drowning. the basic principle of diatom test in drowning is based on the inference that diatoms are present in medium where drowning took place and the inhaled water enters the alveolar spaces of lungs and penetrates from the alveoli into the blood circulation, thus microscopic unicellular algae c...

in the present study, the increase of organic loading rate (olr) influences the biomethanisation of sewage sludge. the research was conducted at technical scale in wastewater treatment plant in tyrowo (near ostróda, poland). it has been shown that the increase of olr, by adding co-substrates, cause the increase of biogas production but not biogas yield coefficient. the substrates used for anaer...

To find out the psychological root cause of Secure System Development (SSD) innovation digestion behavior, this article establishes the double digestion model of SSD innovation based on psychological factors. The theoretical bases include the acceptance model, motivation theory and theories related to innovation digestion. Then, we use SPSS 19.0 and AMOS 17.0 to verify the model. The results in...

Co-digestion is the simultaneous digestion of two or more substrates and a common practice at wastewater treatment plants (WWTPs). The amounts methane digested sludge produced are key parameters for evaluating economic efficiency co-digestion. However, share dewatered digestate from co-substrates not known. Synergistic effects in co-digestion, i.e. better biodegradability compared to mono-diges...

To investigate the conditions of microwave digestion for determining Iron in milk powder by flame atomic absorption spectrophotometry(FAAS), the content of iron in milk powder was determined by flame atomic absorption spectrophotometry after the samples were microwavely digested under different conditions. The optimum parameters for microwave digestion were obtained by the orthogonal test at la...

Complete coverage of all phosphorylation sites in a proteome is the ultimate goal for large-scale phosphoproteome analysis. However, only making use of one protease trypsin for protein digestion cannot cover all phosphorylation sites, because not all tryptic phosphopeptides are detectable in MS. To further increase the phosphoproteomics coverage of HeLa cells, we proposed a tandem digestion app...
