This problem originated in an attempt to make methyl glyoxal in quantity. Several methods of making methyl glyoxal are mentioned in the literature but in none of them is acetone used as a starting point. Since this seemed a new field it was decided...
Vertical pair of signs for Sterns Golden Eagle Coal. The top sign reads "Sterns Golden Eagle Coal. Save Money - More Heat - Less Ash" with a picture of an eagle. The bottom sign reads "Sterns Golden Eagle Coal. Sterns Coal Co.-...
Address: 1127 S. Seventeenth Street, Louisville, Kentucky. A brick apartment building is shown in a residential area. A small sign declares it Ruby Apartments. Another sign reads, "For Rent to colored. These modern apartments, two rooms &...
A number of automobiles and trucks are parked in front of buildings on Main Street. The building partially showing on the left is Bosler Bros. Leather & Findings. A sign in the window advertises, "Shoemakers Supplies, Shoe Machinery,...

“Johnson is a practitioner of a style sometimes labeled ‘abstract illusionism’, making paintings where apparently solid but abstract forms float in illusionary space. Riverfront Break may have been suggested by the industrial forms of the...
High solids processing of biomass slurries provides the following benefits: maximized product concentration in the fermentable sugar stream, reduced water usage, and reduced reactor size. However, high solids processing poses mixing and heat...
The thesis focuses on improving the flowrate of the Knudsen gas pump. The Knudsen pump uses thermal transpiration as the driving mechanism to pump gas. It is a motionless gas pump as the pump does not require any moving actuators for pumping. The...

The one dimensional heat transfer, thermal diode effect of heat pipes makes
them ideal for passive solar applications. Gains in a heat pipe passive solar wall are not
lost during cloud cover or periods of low irradiation. An experimental model was...
The synthesis of the methyl thioperoxide-bridged dimolybdenum(V) dimer, [Mo2(NTo)2(S2P(OEt)2)2S(O2CMe)(SOMe)], was improved and the compound was structurally characterized by crystallography. The compound proved to be very stable to light and heat....
Dermal wounds, including bed sores, pressure ulcers, and diabetic ulcers have a large impact on American healthcare costing up to $7 billion per year. Adequate pharmaceutical remedies applied at constant rate could prove to increase the healing...
A man and two boys carry signs for the Transport Workers Union. One reads, "[Employees] want more - Service - Safer running time - More heat on street cars." Another sign reads, "Louisville Railway defies the civil rights of...
Three men stand with signs on top of trolley tracks. One wears a trolley conductor's hat with the number 899 on it. Signs read, "Lou. Railway unfair to organized labor," "Lou. Railway employees want more - Service - Safer running...
Liver--Diseases--Genetic aspects; Liver--Effect of arsenic on; Arsenic--Toxicology
Arsenic exposure in drinking-water is a significant worldwide health problem. It causes adverse human health effects, such as cancer, increases the risks for others such as cardiovascular disease, and accelerates atherosclerosis. In this study, we...

At the World's Fair in St. Louis, Missouri, a Mexican man wearing a sombrero, probably Jesus Tobano, sits on a plank connected to a piece of machinery; he is holding onto two ropes and his feet are resting on two spools of copper wire. In front of...
This dissertation is concerned with investigating robust approaches for the control of pneumatic muscle systems. Pneumatic muscle is a novel type of actuator. Besides having a high ratio of power to weight and flexible control of movement, it also...
The Knudsen pump works on the principle of thermal transpiration. As a result of requiring a thermal gradient, channel hydraulic diameter smaller than the mean free path of the gas being pumped, and having no moving parts, the Knudsen pump features...
Nanoparticles; Drug delivery devices; Gene therapy
The properties and broad applications of nano-magnetic colloids have generated much interest in recent years. Specially, Fe304 nanoparticles have attracted a great deal of attention since their magnetic properties can be used for hyperthermia...
