The effect of COD/N ratio on the granulation process and microbial population succession was investigated. Four identical sequencing batch reactors, R1, R2, R3 and R4, were operated with various initial COD/N ratios ranging from 0/200 to 800/200 (m/m). Ethanol was fed as the source of COD. Aerobic granules were successfully cultivated in R2 and R3, operating with the COD/N ratio of 200/200 and ...

Kampung Unggul Balitnak (KUB) is a native chicken crossed for six generations. Rice bran an energy source of feed, but rice has high crude fiber. The research was conducted in the poultry production cage Sasa Village, South Ternate City. This study aimed to determine percentage fermented performance KUB Village meat production. used Completely Randomized Design (CRD) consisting five treatments ...

The frequencies of vocal tract resonances estimated using whisper and creak phonations are compared with those in normal phonation for subjects who produced pairs of these phonations in the same vocal gesture. Peaks in the spectral envelope were used to measure the frequencies of the first four resonances (R1-R4) for the non-periodic phonations, and broadband excitation at the mouth was used to...

BACKGROUND 1,3-Dipolar [3 + 2]-cycloaddition of nitrones to the carbon-carbon double bonds of methylenecyclopropanes yields a mixture of regioisomeric 4- and 5-isoxazolidines. The mechanisms of the reactions of N,C,C-trisubstituted nitrones with ring acceptor substituted dimethyl methylenecyclopropanes-1,2-dicarboxylate and aryl methylidene cyclopropanes-1,1-dicarboxylate have been investigated...

BACKGROUND & OBJECTIVES Listeria monocytogenes is an important food-borne pathogen causing meningitis and septicaemia in newborns and immunocompromised persons, abortion and preterm labour in pregnant women. Though various methods are available for typing L. monocytogenes, RAPD analysis has been used for epidemiological purposes in developed countries due to its greater discriminating ability. ...

Four requirements are suggested for an axiomatic system S to provide the foundations of category theory: (R1) S should allow us to construct the category of all structures of a given kind (without restriction), such as the category of all groups and the category of all categories; (R2) It should also allow us to construct the category of all functors between any two given categories including t...

The endogenous opioid system, essentially constituted by two opioid receptors which are stimulated by the natural internal effectors enkephalins (Met-enkephalin and Leu-enkephalin), is present at the different sites (peripheral, spinal, central) of the control of pain. We have demonstrated that the protection of the enkephalin inactivation by the two metallopeptidases (neprilysin and neutral am...

The feasibility of power generation by non-destructive usage of rhizodeposits of Pennisetum setaceum plant formed mainly due to photosynthesis-carbon sequestration mechanism was studied in rhizosphere based microbial fuel-cell (R-MFC). Four fuel-cell assemblies (non-catalyzed graphite-plates; membrane-less operation; air-cathode) were evaluated for their electrogenic activity by varying anode d...

OBJECTIVES To determine the test-retest reliability and minimum detectable change scores for seven common clinical measurements of muscle strength and physical function in a multiethnic sample of sarcopenic, malnourished men and women. DESIGN Each participant visited the laboratory seven times over 25 to 26 weeks. Reliability was assessed for each measurement from Familiarization 1 to Familia...

Root shape is an important characteristic that affects the commodity of radish (Raphanus sativus L.), which can be measured using ratio root length (RL) to diameter (RD). Although it known controlled by quantitative trait loci (QTLs), reliable QTLs for are still lacking. In present study, we used three F2 populations (1902, 1908 and 1909) derived from crossing five cultivars with highly diverge...
