Three practical diets were formulated to contain 0, 500, or 1000 ppm genistein. The three diets were distributed for 1 year to groups of rainbow trout undergoing their first gametogenesis and until spawning. Growth performance of rainbow trout was not affected by dietary treatments. Plasma cholesterol levels were equivalent between groups. In males, a slight but constant induction of vitellogen...

Receptors that transport vitellogenin (VTG) into oocytes are of vital importance to egg-laying species because they mediate a key step in oocyte development. Here we describe the cloning of the first piscine oocyte-specific receptor cDNA, i.e., that encoding the VTG receptor from the rainbow trout (Oncorhynchus mykiss). The receptor, a 826-residue type-I membrane protein, is a member of the low...

How much assistance should be provided to students as they learn with educational technology? Providing help allows students to proceed when struggling, yet can depress their motivation to learn independently. Assistance withholding encourages students to learn for themselves, yet can also lead to frustration. The web-based inquiry-learning program, Voyage to Galapagos (VTG), helps students “fo...

When it comes to nourishing their young, mammals are a motley crew. They all produce milk, but beyond that it gets interesting. The two groups of therian, or live-bearing, animals— eutherian (placental) and metatherian (marsupial) mammals—feed their young in utero, but differ in that marsupial pregnancies are extremely short. (And just to make things more confusing, marsupials have a placenta, ...

Vettumaran Gutika produced moderate CNS depressant effect, prolonged pentobarbitone and diazepam induced sleep, produced initial depression followed by stimulation of SMA in mice. It did not effect SCR and CAR in rats, reserpine effects in mice and threshold of tail-flick response in rats. It failed to protect rats and mice aginst Electro, pentylenetetrazol and strychnine induced convulsions an...

The Las Vegas Wash (LW) delivers tertiary-treated municipal wastewater effluent, nonpotable shallow groundwater seepage, and runoff from the urbanized Las Vegas Valley to Las Vegas Bay (LX) of Lake Mead. To investigate the potential for contaminants in LW influent to produce effects indicative of endocrine disruption in vivo, adult male and female common carp (Cyprinus carpio) were exposed in c...

This Paper introduces a Model Based Predictive Controller to control simultaneous boost pressure and EGR-rate at a diesel engine [5]. In the course of the project „ATECS“ (Advanced Truck Engine Control System), founded by the European Community, a non-linear simulation model of truck diesel engine in Matlab/Simulink was developed by the Institute of Automatic Control (IRT) of the RWTH Aachen in...

Internal combustion engine (ICE) exhaust gases provide a high amount of energy which is partially lost to the environment. Such can be recovered with turbocharger turbine or other after-treatment device. As flow varies not only load but also opening and closing valves, proper matching between should established maximize recovery waste energy. That why twin-scroll dual turbocharging system imple...
