cement production is an energy-intensive process, so that the cement industry occupies a top position among other energy-consuming industries. among the equipment used in cement industries, boilers are one of the energy-consuming equipment. boilers are among the common heating equipment in industrial, commercial, and institutional facilities. in this paper, the performance of thermal oil boiler...

copper is a micronutrient which its, deficiency can alter essential functions in plant metabolism. on the other hand, excess copper is present in certain regions and environments, and can be potentially toxic to plants causing phytotoxicity by the formation of reactive oxygen species that damage cells. in this study, we examined the effect interactions between various concentrations of sodium n...

abstract the existence of various perceptions related to the efficiency of water use in agricultural sector can hamper the development of appropriate water resource conservation policies. particularly, when there has been an emphasis on increasing water use efficiency by improvement in irrigation systems. the main purpose of current study is to estimate excess water use for a sample of 15 farms...

We model the ascent and eruption of lunar mare basalt magmas with new data on crustal thickness and density (GRAIL), magma properties, and surface topography, morphology and structure (Lunar Reconnaissance Orbiter). GRAIL recently measured the broad spatial variation of the bulk density structure of the crust of the Moon. Comparing this with the densities of lunar basaltic and picritic magmas s...

A general formalism for calculating parameters describing physiological acid-base balance in single compartments is extended to multicompartment systems and demonstrated for the multicompartment example of human whole blood. Expressions for total titratable base, strong ion difference, change in total titratable base, change in strong ion difference, and change in Van Slyke standard bicarbonate...

Any recession by definition is associated with an excessive liquidity preference. An ex ante excess supply of goods and services, i.e. the demand for goods and services falling short of the base output at the base prices corresponding to that output, which is what a recession is, must be associated with an ex ante excess demand for money at that output and prices. This is simply Walras’ Law. Th...

A slight excess of silyl trifluoromethanesulfonate mediates a tandem enol silane formation-Mukaiyama aldol reaction in the presence of Hunig’s base. Preformation of the enol silane is unnecessary for efficient reactions, which proceed in 75-97% yield for the addition of aryl methyl ketones and acetate esters to non-enolizable aldehydes. Mechanistic data suggests that free amine is crucial for f...

BACKGROUND Prolonged storage of red blood cells (RBCs) leads to fundamental changes in both the RBCs and the storage media. We retrospectively evaluated the relationship between the RBC age and in-hospital and long-term postoperative outcomes in patients undergoing off-pump coronary artery bypass. METHODS The electronic medical records of 1,072 OPCAB patients were reviewed and information on ...

Sir,—Dr Pandit and his colleagues suggest that patients develop a mixed respiratory and metabolic acidosis following a thoracotomy {Brit. J. Anaesth. (1973), 45, 79). However, the results they present do not necessarily support this conclusion. The investigation would have been more convincing if measurements had been made at each stage in all the patients. Incidentally, there are some discrepa...
