The reduction in uniaxial compressive strength (UCS) was investigated for sandstones under various moisture levels. Thirty-four UK Darney sandstone samples were tested six different conditions. time-dependent gain and loss also evaluated. For 77 identified the literature, of UCS between oven-dry saturated conditions up to 45%, with an average 20%. stone, around 20%, 72 N/mm2 when 58 fully satur...

The influence of different drying methods on physical and nutritional properties of shrimp meat was investigated in this study. Peeled shrimps were dried separately using an air-oven dryer and a tunnel solar dryer. The drying profile of shrimp meat was determined in the two drying systems by monitoring moisture loss over the drying period. Changes in color, proximate composition, and rehydratio...

According to WHO standard the RF leakage beyond +10 dBm are hazardous to human being. The microwave oven is a kitchen appliance which is used in day to day life. But, until 1967 an affordable and compact microwave oven was not readily available for domestic use. The obvious cooking advantages provided by the microwave oven ensured that its uptake would be rapid. It is extensive with up to 90 pe...

Production of iron through BF route is still a dominant route and coke is a major raw material and energy source for the blast furnaces. The process of coal carbonization in slot ovens is one of the major sources of atmospheric pollution in an Integrated Steel Plant. Coke making process involves coal preparation, carbonization and coke handling operations. To meet the demand of Blast Furnaces o...

BY KENNETH MAINORD M any are familiar with "cleaning with heat" whether they realize it or not. Abandoning their rubber gloves, scrub brushes, and chemical cleaners, millions of households across America have been quick to accept a better and easier way to clean their kitchen ovens. This ready acceptance has made the self-cleaning oven one of the most successful new products introduced to the c...

Considering a constant demand in construction of concrete structures to develop novel approaches for predicting the concert’s properties, host investigations were performed on concrete’s mechanical properties and durability under various curing regimes. However, few studies concerned with evaluating using non-destructive surface resistivity tests by applying conditions. The present study compar...

Carbon monoxide (CO) and carbon dioxide (CO2) emissions during a spontaneous heating event in a coal mine are important gases to monitor for detecting the spontaneous heating at an early stage. However, in underground coal mines, the CO and CO2 concentrations and their related fire ratios may be affected by mine ventilation. In this study, CO and CO2 emissions from spontaneous heating of a U.S....

STATEMENT OF PROBLEM Disinfection of prostheses with chemical solutions has deleterious effects on dentures. The appropriate power setting of microwave for disinfection, without affecting denture base properties, is a controversy. PURPOSE To evaluate and compare the effect of simulated microwave disinfection at a recommended power setting on the mechanical properties of three denture base hea...

The microwave leakage from current microwave ovens, which are manufactured to meet government emission standards, is reviewed. Typical leakage values imply exposure values well below the most conservative exposure standards in the world. A review of recent developments discloses increasingly stringent government regulation along with advances in techniques for suppression of microwave leakage. ...
