Starting with a brief review of millimeter wave research and development, basic concept, theory and applications of NRD-guide technology are described. A particular emphasis is placed on short distance propagation of millimeter waves such as indoor HD-TV wireless transmission and Giga-bit video downloader. It is also emphasized that NRD-guide can offer advantages of easy fabrication, low cost a...

cryptosporidium is an apicomplexan parasite of humans and a wild range of domestic as well as wild animals. an 833-bp fragment of the 18s-rrna gene was used to identify cryptosporidium spp. recovered from children and adult patients, in human immunodeficiency virus (hiv) positive and negative patients in iran. initial identification of cryptosporidiosis was carried out by ziehl-neelsen acid-fas...

Despite the significance of diatoms in biomonitoring, many aspects of their biodiversity and geographical distribution are poorly understood. Recent evidence from molecular data has shown that traditional cosmopolitan and euryvalent morphospecies are often heterogeneous, containing cryptic or pseudo-cryptic species. It is important to establish whether these more finely differentiated species a...

early diagnosis of bacteremia and its complications is the most important part of care and management of the febrile patients. however, a majority of patients who appear to be clinically septic have negative blood culture. the use of polymerase chain reaction (pcr) techniques has allowed identifying the pathogenic organisms rapidly and accurately. the objective of this study was to investigate ...

Tissue samples were collected from coconut palms with symptoms of lethal yellowing (LY) disease in Jamaica. Palms were sampled at 50 sites exhibiting varying levels of mortality due to LY. Samples were assayed for phytoplasma infection by polymerase chain reaction (PCR) assays. Detected phytoplasmas were characterized by dot blot nucleic acid hybridisation, restriction fragment length polymorph...
