Reinforced capsules

For these tests, Clark placed a small charge of HE in a No 8 detonator shell and pressed it under a reinforcing capsule at 3400 psi. The detonator was placed centrally in a cylindrical oaken shield, with its long axis parallel to and...

Reinforce the dosage instructions advise that the capsules are best taken with or after food to help prevent stomach irritation. Taking with milk will also protect the stomach... 

The traditional TPS for launcher fairings and re-entry capsules consists of an external ablative insulation, fixed or bonded onto a metallic primary structure. Ablative materials are based on thermosets (phenolic and epoxy resins) or elastomers (ethylene-propylene and silicone rubbers) usually filled and reinforced with cork, cotton, glass, silica, quartz, carbon, silicon carbide, nylon and aramid in the form of powders, fibres, fabrics and felt (Table 2). 

Because of their stout formation the transverse fibers reinforcing the joint capsules appear to play an important role in the mechanism of the... 

Polyelectrolyte capsules reinforced by inorganic nanoparticles are able to incorporate internally, in controlled manner, a variety of different organic as well as bioor-ganic materials (drugs, polymers, enzymes, etc.) [58], In this respect, YF3/PAH capsule permeability and release properties were studied by employing fluorescein isothiocyanate (FITC)-labeled dextran of 2000 kDa molecular weight as a probe.

The possibility of anisotropic insertion of the capsules into the foam can reinforce the regulator effect by concentrating PCMs towards the interior of the clothing. This provides excellent moisture management as well as thermal control. 

Formation of microcapsules by in situ interfacial polymerization (where the monomers are entirely in the oil phase of the capsule core) yields microcapsules with a high core-to-wall ratio and a bilayer wall with an outer layer (about 0.05 urn) and an inner reinforcing spongy layer (0.5 fim). This method has been used to encapsulate a range of insecticides, pheromones, and herbicides, many of which have been available commercially (37). The capsule size may be varied from submicrometer to 100 /um diameter and the permeability selected for rapid or slow release of... 

Abuse liability is the potential for a drug to produce positive effects that will reinforce a pattern of misuse, abuse, or diversion. To date, there is no evidence that the naltrexone component of combined morphine/ naltrexone will prevent or deter abuse. Novel abuse liability trials have been developed to assess the effects of combined morphine/naltrexone when tampered with. The pharmacodynamic effect of naltrexone in the setting of crushed morphine/naltrexone capsules was examined in two clinical trials an oral and an intravenous abuse liability trial [8]. These were conducted in nondependent recreational opioid abusers, as dependent, daily or habitual users would probably experience a withdrawal syndrome when exposed to the naltrexone component with crushed morphine/ naltrexone capsules.
