A central composite experimental design was used to investigate the influence of environmental composting parameters (moisture, aeration, particle size and time) for legume trimming residues, used on soil restoration, on the properties of products obtained (organic matter, Kjeldahl-N, C/N ratio and nitrogen losses (N-losses)) in order to determine the best composting conditions. A second-order ...

Kibdelosporangium albatum No. R761-7 (ATCC 55061) produced new antiviral antibiotics, cycloviracins B1 and B2. They show weak activity against Gram-positive bacteria and potent antiviral activity against herpes simplex virus type 1. Unique acylsaccharide structures were established for cycloviracins B1 and B2 by degradation and spectroscopic analysis.

We have performed a systematic density functional study of surface energy of MoS2 films as a function of thickness from one to twelve layers with the consideration of van der Waals (vdW) interactions using the vdW-DF and DFT-D2 methods. Both vdW schemes show that the surface energy will increase with the increase of the number of atomic layers and converge to a constant value at about six layer...

The aim of this work was to study the parameters of the composting process of organic wastes originated from mushroom production industry. To accomplish these objectives three piles (P1, P2 and P3) obtained with a spent mushroom substrate (SMS) with different proportions of wheat straw (WS) and urea were composted for 90 days in a static-pile system with continuous monitoring of the process. Sa...

This review presents the summary of new studies on pyrolysis of biomass to produce fuels and chemical feedstocks. A number of biomass species, varying from woody and herbaceous biomass to municipal solid waste, food processing residues and industrial wastes, were subjected to different pyrolysis conditions to obtain liquid, gas and solid products. The results of various biomass pyrolysis invest...

The effect of artificial pozzolan (waste brick) on the physico-chemical properties of cement manufactured was investigated. The waste brick is generated by the manufacture of bricks. It was used in the proportions of 0%, 5%, 10%, 15% and 20% by mass of cement to study its effect on the physico-chemical properties of cement incorporating artificial pozzolan. The physicochemical properties of cem...

in this study, geometrical, gravimetrical and frictional properties of four common varieties of iranian canola seeds (namely: slm, hyola, okapi, orient), containing the mean moisture value of 6.5% (w.b.) were investigated. geometrical and gravimetrical properties included length, diameter, geometric mean diameter, sphericity, thousand seed mass, volume, true density, bulk density and porosity. ...

In 1919 Haggard and Henderson (1) outlined a method for the direct determination of the carbon dioxide tension of arterial and venous blood. They also demonstrated the applicability of the method to the study of abnormal physiological conditions involving disturbances of the respiratory system and the acidbase equilibrium in the blood. Stadie’s (2) demonstration of the practicability of arteria...

Dysfunction of the autonomic nervous system is a well established long term complication of diabetes mellitus. Moreover, autonomic innervations is essential for appropriate functioning of the gastrointestinal tract, (GI), including the synchronicity between the motility induced peristaltic movement and the sphincters as well as the secretary capacity of the GI glands, i.e. salivary glands, panc...

For nearly 100 years, the extraordinary catalytic power of enzymes has fascinated biochemists (1). In a recent article in this Journal, Splittgerber (2) analyzed several ofthe factors by which enzymes are thought to effect catalysis, including proximity and orientation effects, substrate strain, acidbase catalysis, and nucleophilic catalysis. Here we will discuss the fundamental role that the f...
