ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...

Some Experiments With Turf On Granular Materials

The maintenance of turf on shoulders, berms, and ditches of our highways and on airports has received little attention until very recent years. Frequently a good turf is desirable where the soil has been stabilized or where granular materials are necessary to obtain sufficient supporting power for the anticipated load. Under such conditions attention must be given to the factors which influence...

Urease inhibitors: A review

Urease inhibitors possess a wide application in agriculture, clinical science and understanding of enzyme kinetics. These inhibitors play a significant role in reducing the loss of nitrogen from urea fertilizer in the form of volatile ammonia and, thus, improve the utility of urea based fertilizers. Their impact as an effective drug against urease producing bacterial infection is well documente...

Application of Oligomers with Urea Linkage as Flame Retardant and Antibacterial Materials in Jute Fabric

Determination of urea in serum based on the combination of an enzymatic reaction with immobilized urease and ion chromatographic analysis.

A quantitative method for the determination of urea in serum was studied. An ion chromatograph (IC) with a conductivity detector was used in this method, where the chromatograph was modified by placing an immobilized urease column between the injection loop and a guard column of the cation analysis column. Immobilized urease was prepared by the adsorption of urease on cedar sawdust with triethy...
