Abstract Construction and demolition wastes (CDW) are a concern in urban areas, addition, it is well understood that soft soils inappropriate for paving designs. Therefore, this paper presents an alternative solution combining CDW silty soil, aiming to overcome the soil drawbacks by repeated loadings. For purpose, laboratory study was developed, comprising both resilient modulus (M R ) unconfin...

1. Dry weight, body length and spine length were measured for the exotic cladoceran Bythotrephes cederstroemii collected from offshore and inshore stations in southeastem Lake Michigan. Average dry weight of each developmental stage exhibited seasonal variation by a factor of more than 5. 2. Mean dry weight of Bythotrephes was closely correlated with water temperature. Contrary to the inverse r...

Seasonal fluctuations in mean dry weight of the copepod Calanus helgolandicus were large and contrasted markedly with the small seasonal fluctuations of cephalothorax length. Dry weight was related linearly to cephalothorax length on logarithmic axes by a series of regression equations which were significantly different for each of 8 cruises. Carbon and nitrogen were likewise linearly related t...

Firebricks are generally used in furnace basins where glass, ceramics, and cement produced. have an important place construction demolition waste (CDW). However, there is a limited understanding of the effects on fresh hardened state properties cementitious composites. This study investigates mechanical, physical, microstructural composites incorporating firebrick powder (FBP) from CDW. In this...

Previous energy-dispersive x-ray analysis studies of globoid crystal composition in seed protein bodies gave an indication that there might be a correlation between seed size and the type of elements stored in globoid crystals. This possibility was tested by conducting energy-dispersive x-ray analysis studies of P, K, Mg, and Ca levels in globoid crystals of four embryo regions (radicle, stem, ...

The present study evaluated the hypothesis that the effects of hypoxia on sheep pregnancies at high altitude (HA) are mediated by oxidative stress and that antioxidant vitamins may prevent these effects. Both HA native and newcomer ewes were maintained at an altitude of 3,589 m during mating and pregnancy. Control low altitude (LA) native ewes were maintained at sea level. Half of each group re...

We present angular dependent magneto-transport and magnetization measurements on α-(ET)2MHg(SCN)4 compounds at high magnetic fields and low temperatures. We find that the low temperature ground state undergoes two subsequent field-induced density-wave type phase transitions above a critical angle of the magnetic field with respect to the crystallographic axes. This new phase diagram may be qual...

Identifying key yield components can help establish better crop management strategies to increase crop yield. The present research was conducted in south-western Saskatchewan in 1999 and 2000 to determine the interrelationships among various yield components and their direct and indirect effects of each component on seed yield of field pea (Pisum sativum L.). The semi-leafless cultivar Carrera ...

Recent papers have brought evidence against the hypothesis that the fucosyl branching of primary wall xyloglucans (Xg) are responsible for their higher capacity of binding to cellulose. Reinforcement of this questioning has been obtained in this work where we show that the binding capacity was improved when the molecular weight (MW) of the Xg polymers is decreased by enzymatic hydrolysis. Moreo...
