variation in growth, feed utilization and survival was assessed in sturgeon fingerlings of beluga fed different dietary lipid levels. all diets were iso-nitrogenous (protein = 45%) comprising 3.4-3.7 kcal digestible energy g-1. triplicate groups of 35 fingerling beluga with a mean initial wet weight of 2.14 ± 0.07 g (± sd) were fed with four experimental diets containing 6.7, 10.5, 14 and 17% c...

ITE JOURNAL / JUNE 2000 ARTERIAL CAPACITY PROBLEMS The function of an arterial is efficient movement of large traffic volumes over a significant distance.1 As arterial traffic volumes approach roadway capacity, delays grow rapidly at signalized intersections with significant cross-street volumes, diminishing the ability of the arterials to help traffic move effectively. Under conventional arter...

Waste management is a major problem to which the agricultural and food industries must find solutions. The latter use pineapple in most of processes for manufacture fruit juices. These result tons waste that are often abandoned on dumps near processing plants, polluting water table quality surface after drainage by rainwater. Our study therefore proposed an efficient solution this valorizing ag...

Nitrogen is essential for plant survival and growth. Excessive application of nitrogenous fertilizer has generated serious environment pollution and increased production cost in agriculture. To deal with this problem, tremendous efforts have been invested worldwide to increase the nitrogen use ability of crops. However, only limited success has been achieved to date. Here we report that NLP7 (N...

background and objective: an outer membrane protein (omp) of helicobacter pylori namely oipa, is an important vir- ulence factor associated with peptic ulcer and gastric cancer risks. the purpose of this study was to isolate the 34 kda omp of h. pylori and evaluate its immunogenicity in experimental animals for rapid detection of more virulent h. pylori isolates. material and methods: sarcosine...

All nitrogenous substances completely metabolized in the organism of mammals are removed by the urine in form of urea. Every other nitrogenous constituent of the urine is either a substance which has for one reason or another escaped its final transformation, or has not been metabolized by the organism at all. Under metabolism here, of course, is understood a set of chemical reactions which res...

We measured minimal nitrogen requirements (MNR), total endogenous nitrogen loss (TENL) and the effect of protein and water intake on the nitrogenous waste composition in two frugivorous bird species: yellow-vented bulbuls Pycnonotus xanthopygos and Tristram's grackles Onychognathus tristrami. The nitrogen requirements of both species were much lower than expected for their body mass. The two sp...

This paper, although limited to the effects of homologous antibodies acting as inhibitors of the sporulation process of bacterial cells, is one of a series of current investigations of various physiological factors concerned in sporogenesis. The essentials for sporogenesis recently have been hypothesized and experimentally supported by Hardwick and Foster (1952). They point out, with good evide...
