This work describes the development of spray dried polymer coated liposomes composed of soy phosphatidylcholine (SPC) and phospholipid dimyristoyl phosphatidylglycerol (DMPG) coated with alginate, chitosan or trimethyl chitosan (TMC), that are able to penetrate through the nasal mucosa and offer enhanced penetration over uncoated liposomes when delivered as a dry powder. All the liposome formul...

In the present experiment, 320 one day old Ross 308 broiler chickens were used completely randomized design with 4 treatments, 4 replicates, and each replicate contained 20 broiler chickens. Experimental treatments include control, 0.5, 1, and 2% of Thymolina powder in chickens’ diet. Thymolina is an antibacterial powder drug which is made by composing 4 medicinal plants. A significant differen...

this experiment was conducted to investigate the effects of garlic powder on fermentation characteristic and rumen microbes of arabian sheep.at first step the best level of garlic was determined. then animals were fed for 35 days with control diet and supplemented with garlic (2% per kg dm). apparent digestibility, rumen fermentation parameters, number of protozoa and blood metabolites (glucose...

The release characteristics of flavor in boiling water and the flavor retention in the rice after cooking were investigated by using spray dried powder in encapsulated in or emulsified with d-limonene or ethyl n-hexanoate in cyclodextrin and maltodextrin, or in gum arabic and maltodextrin. The behavior of flavor release into the boiling water was well simulated by Avrami's equation. The retenti...

An acetone powder of cat brain catalyzed the synthesis of two radioactive products when incubated with L-aspartate-14C and acetyl coenzyme A. The products were identified as Nacetyl-aspartic acid and citric acid. A water extract of the powder contained the system that produced citrate-14C, while the residue contained the aspartate N-acetyltransferase activity. The soluble system rather than the...

Highly luminescent ZnO:Ga-polystyrene composite (ZnO:Ga-PS) with ultrafast subnanosecond decay was prepared by homogeneous embedding the ZnO:Ga scintillating powder into the scintillating organic matrix. The powder was prepared by photo-induced precipitation with subsequent calcination in air and Ar/H2 atmospheres. The composite was subsequently prepared by mixing the ZnO:Ga powder i...

In powder die compaction, the characteristics of the end product are dictated by the mechanical properties of the powder being processed. A commonly used constitutive model describing the behavior of pharmaceutical powders during compaction is the modifi ed-Drucker Prager Cap (DPC) model. The experiments used to measure DPC parameters are time consuming and, hence, limit the model’s wide-spread...

Characterization of the pore structure of compacted and sintered parts made from a nickel-base powder was accomplished using the mercury porosimetry method. The theoretical density values for the sintered specimens varied from 56.3 to 96.7% which corresponds to a porosity of 43.7 to 3.3%. A maximum interconnecting median pore diameter of 21 mum resulted from a -80/+200 mesh powder compacted at ...

Dry powder formulations are often composed of fi ne drug particles and coarser carrier particles, typically -lactose monohydrate because it is an inert, cheap, broadly available and non-toxic excipient1. However, the effi ciency of a powder formulation may be highly dependent on the lactose quality and source2. Indeed, interactions between particles are mainly dependent on the physicochemical c...

This study investigated the hydration characteristics and strength development of calcium sulfoaluminate-belite (CSAB) cements incorporating calcium carbonate (CC) powders with various particle size distributions and different gypsum amounts. In general, the CSAB hydration was accelerated by the CC powder, but the acceleration and resulting strength improvement were more effective with finer CC...
