Optical transmission spectrum measurements in an electric field are used to study the short-range structure of the blue phase III (BPIII). The data are compared with the theoretical models for BPIII. Our results can be explained by the models in which BPIII has the simple-cubic local structure or cubic bond orientational order.

Pharmacotherapy is a major treatment method in healthcare centers, and the injection of powdered drugs is among common pharmacotherapy techniques. Medication errors and nosocomial infections are among major health issues in the world. On the other hand, powdered drugs are widely used in hospitals; however, drug mixture is a very time-consuming process. The objective of this invention was to acc...

totally implantable venous access devices (tivad) or implantable catheter ports are devices which can be implanted subcutaneously. they enable prolonged and repeated access to the vascular system, into the peritoneal cavity or intravertebral space. this device is particularly useful for repeated medical injection, for blood sampling or transfusion of blood and blood derivatives and for total pa...

device-associated nosocomial infection is a significant part of nosocomial infection and can cause the majority of its mortality, morbidity, extra lengths of hospital stay and cost. in a 13-year review, the online database was searched for full articles to find research on epidemiology of device-associated nosocomial infection in pediatric and neonatal wards. twenty two papers were included fiv...

statement of problem: snoring is the most common sleep disorder which in itself may only be viewed as an obnoxious disturbance in human society; however it must be considered a potential indicator of significant medical problems such as: hypertension, obstructive sleep apnea, cerebrovascular infarction and ischemic heart disease. purpose: the purpose of this study was to evaluate the effectiven...

A polarizer-free flexible and reflective electro-optical switch using dye-doped liquid crystal (LC) gels is demonstrated. The electro-optical performances of both scattering and absorption based dye-doped LC gels depend on curing temperatures due to domain sizes of polymer networks. Such flexible electro-optical switch is bendable and trim-able because of the vertical polymer networks and gel-l...
