In order to study on different methods of application of polyamines (putrescine, spermine, spermidine) on some morphological, physiological, enzymatic and vase life of Rosa hybrida cv. ‘Dolce Vita’, experiment was conducted as a factorial experiment in a completely randomized design with 32 treatments, 3 replicates and each replication containing 5 vases, a total of 480 vases were executed. Fir...

Title of Document: CO-SOLVENT ASSISTED SPRAY PYROLYSIS FOR THE PREPARATION OF METAL MICROPARTILCE. Kai Zhong, Doctor of Philosophy, 2012 Directed By: Professor Sheryl H. Ehrman, Department of Chemical and Biomolecular Engineering Metal and bimetallic particles play an important role in catalytic, medical and electronic applications. Various techniques have been developed for the preparation of ...

A novel discrete element spray granulation model capturing the key features of fluidised bed hydrodynamics, liquid-solid contacting and agglomeration is presented. The model computes the motion of every individual particle and droplet in the system, considering the gas phase as a continuum. Micro scale processes such as particle-particle collisions, droplet-particle coalescence and agglomeratio...

the effects of various methods of probiotic administration in hatchery and on prevention of salmonella enteritidis (se) in broiler chicks was investigated. a total of 150 salmonella free day old chicks (ross 308) were assigned to five experimental groups including control and four in-hatchery probiotic administration method groups comprised of: in ovo injection, oral gavage, spray and vent lip ...

We report on a facile spray deposition method, which allows obtaining nanocomposite membranes for high-temperature polymer fuel cells characterized by high homogeneity and excellent proton conductivity. The proposed method is also green, as it requires much smaller amounts of solvents with respect to standard casting.

This paper presents three coating methods of photoresist, spin, spray and electrodeposition (ED) on large topography surfaces. Characteristics of each method as well as its advantage and disadvantages are outlined. A comparison is made to point out the most suitable coating method in terms of complexity, costs and type of

In cookware industry, interior spray coating process is an important process to protect the cookware product from the corrosion. In this process, the coating material “TEFLON” is used to spray to cover all the part’s surface. If a pot or pan is not too deep, one spray gun is enough to spray to cover all the interior surface. However, for the high side-wall pot, two spray guns must be used to sp...

The potential utilization of encapsulation techniques in food, pharmaceutical and agricultural products preparation, presents a new alternative for complementary technologies such as targeting delivery vehicles and carriers for active food ingredients. Encapsulation could be accomplished by different techniques like: simple or complex coacervation, emulsification technique, phase separation, sp...

We prepare thin single-walled carbon nanotube networks on a transparent and flexible substrate with different densities, using a very simple spray method. We measure the electric impedance at different frequencies Z(f) in the frequency range of 40 Hz to 20 GHz using two different methods: a two-probe method in the range up to 110 MHz and a coaxial (Corbino) method in the range of 10 MHz to 20 G...

In this paper, a method is presented for lowering the energy consumption and/or increasing the speed of a standard manipulator spray painting a surface. The approach is based on the observation that a small angle between the spray direction and the surface normal does not affect the quality of the paint job. Recent results in set-based kinematic control are utilized to develop a switched contro...
