Delonix regia is commonly called Flamboyant or flame of the forest. The seeds were fermented, boiled, sundried and then ground into powdered meal. 40% crude protein based test diets containing seed meal D0 = 0%; D15 15%; D20 20% D25 25% inclusion levels respectively prepared. Red tilapia (Oreochromis niloticus) fingerlings 6 weeks old acclimatized for two stocked in 12 hapas at 15 fish per hapa...
Employees involved in various occupational environments that include vibration machines and any kind of vehicles are adversely subjected to multiple source noise. Thus, the corresponding noise frequencies (and mainly infrasound ones) present high interest, especially from viewpoint sustainability, due potential effects on human safety health (H_S&H) sustainable engineering projects. Moreove...
Abstract INTRODUCTION In patients treated with radiation (RT), doses to hippocampus influence neurocognitive outcomes. However, the role of hippocampal subvolumes in memory functioning has not been reported, which prompted current study. METHODS Adults ( > 18 years) pituitary tumors fractionated RT (45 Gy/ 25 fractions/ 5 weeks) were accrued prospective Hippocampus was delineated on T1-w...
The influence of solid-liquid demixing, liquid-liquid demixing and vitrification on the morphology of polylactide membranes has been investigated. To study the effects of crystallization of polylactides on the membrane formation and morphology, polylactides of varying stereoregularity were used. The polymers applied were poly-L-lactide (PLLA) and copolymers with different molar ratios of L-lact...
Benkler (‘Sharing Nicely’, Yale Law Journal, 2004, Vol. 114, pp. 273-358) has argued that ‘social sharing’ via Internet-based distributed computing is a new, so far under-appreciated modality of economic production. This paper presents results from an empirical study of SETI@home (the Search for Extraterrestrial Intelligence), which is the classic example of such a computing project. The aim is...
Deuteron spin-lattice relaxation time (TJ measurements of binary mixtures 2,6-lut idine/D20 have been done near the lower critical solution point (Tc L), e = (T — Tg L)/Tc 10~. Singularities are observed at Tc L . The changes in the slope of Ti (H) = / ( T ) can be interpreted as due to the effect of concentration changes on Ty and simultaneously strong overlaping of H N M R signals from coexis...
A fundamental principle of economics with which Adam Smith begins The Wealth of Nations is the division of labor. Some firms, however, have been pursuing a practice called job rotation, which assigns each worker not to a single and specific task but to a set of several tasks among which he or she rotates with some frequency. We examine the practice of job rotation as a serious alternative to sp...
The use of traditional feedstocks for biofuel production has brought about large changes to food and agricultural systems. As livestock producers adapt to rising feed costs, the prospect of incorporating dried distiller’s grain with solubles (DDGS) at higher than traditional levels becomes an important consideration. Given prices for feedstuffs and supplies of DDGS that are outside the historic...
The activation peptide of mammalian trypsinogens contains a highly conserved tetra-aspartate sequence (D19-D20-D21-D22) preceding the K23-I24 scissile peptide bond, which is hydrolyzed as the first step in the activation process. Here, we examined the evolution and function of trypsinogen activation peptides through integrating functional characterization of disease-associated mutations with co...
We analyze a rational-expectations model of price formation in an intermediategood market under uncertainty. There is a continuum of dyads, each consisting of an upstream party and a downstream party. Both parties can make speci c investments at private cost. As in property-rights models, di¤erent governance structures induce di¤erent investments. As in rational-expectations models, some partie...
