The reaction of gem-dithiol compounds R 2C(SH) 2 (R = Bn (benzyl), (i) Pr; R 2 = -(CH 2) 4-) with dinuclear rhodium or iridium complexes containing basic ligands such as [M(mu-OH)(cod)] 2 and [M(mu-OMe)(cod)] 2, or the mononuclear [M(acac)(cod)] (M = Rh, Ir, cod = 1,5-cyclooctadiene) in the presence of a external base, afforded the dinuclear complexes [M 2(mu-S 2CR 2)(cod) 2] ( 1- 4). The monod...

BACKGROUND Cod liver oil is an important source of vitamin D, but also contains other fat-soluble components such as vitamin A. Before 1999, the cod liver oil formula in Norway contained a high concentration of vitamin A (1000 µg per 5 ml). High vitamin A status is associated with increased risks of several chronic diseases. OBJECTIVE To investigate the association between cod liver oil intak...

Grey model (GM) and artificial neural network (ANN) was employed to predict suspended solids (SS) and chemical oxygen demand (COD) n the effluent from sequence batch reactors of a hospital wastewater treatment plant (HWWTP). The results indicated that the minimum mean bsolute percentage errors (MAPEs) of 23.14% and 51.73% for SS and COD could be achieved using genetic algorithm ANN (GAANN). The...

Partial nitrification was reported to be technically feasible and economically favorable, especially for wastewater with high ammonium concentration or low C/N ratio. In this study, the effect of dissolved oxygen (DO) and influent ratio of chemical oxygen demand to nitrogen (COD/N) ratio on biological nitrogen removal from synthetic wastewater was investigated. Experiments were conducted in mov...

Low-protein and high-protein diets regulate energy metabolism in animals and humans. To evaluate whether different dietary protein sources modulate energy balance when ingested at average levels obesity-prone male C57BL/6J mice were pair-fed high-fat diets (67 energy percent fat, 18 energy percent sucrose and 15 energy percent protein) with either casein, chicken filet or a mixture of cod and s...

Square COD (complex orthogonal design) with size [n, n, k] is an n×n matrix Oz, where each entry is a complex linear combination of zi and their conjugations z∗ i , i = 1, . . . , k, such that O H z Oz = (|z1| 2 + . . . + |zk| 2)In. Closely following the work of Hottinen and Tirkkonen, which proved an upper bound of k/n by making a crucial observation between square COD and group representation...

COD is usually measured and the test is simple and easy to perform with the right equipment and can be done in 2 hours. BOD usually takes 5 days and TOC used to require large expensive pieces of equipment that could measure the sample in minutes, but was cost prohibitive. There are now test in tube kits that utilize COD digestors to run a test similar to a COD test method. Below are more detail...

Pacific cod (Gadus macrocephalus) inhabits the entire North Pacific region and supports the third largest fishery after walleye pollock (Theragra chalcogramma) and Atlantic cod (Gadus morhua). Although walleye pollock is often processed into various food products, Pacific and Atlantic cod are often preserved using salt for transport and consumption worldwide. Salt suppresses bacterial growth an...

Opioids are central analgesics that act on the CNS (central nervous system) and PNS (peripheral nervous system). We investigated the effects of codeine (COD) and tramadol (TRAM) on local anesthesia of the sciatic nerve. Eighty Wistar male rats received the following SC injections in the popliteal fossa: local anesthetic with epinephrine (LA); local anesthetic without vasoconstrictor (LA WV); CO...
