An efficient finite volume approach has been used to develop a three dimensional Helmholtz acoustic solver for complex geometries. This acoustic solver was utilized to obtain characteristic mode shapes and frequencies of a baffled combustion chamber. An experimental setup, including stationary and moving sensors, has also been used to measure these quantities for the same model combustion chamb...

In this paper, the reflection of ultrasonic guided waves from simple dent in pipes has been investigated using finite element method and the relationship between reflection coefficient of these waves and deformation rate has been determined. Also, the effect of the parameters of wave generation source on the generated wave field has been investigated using normal modes expansion method. At firs...

the cytoplasmic male sterile (cms) lines that are used in production of hybrid seeds in three-line system often get contaminated with their maintainer lines. using such impure cms lines in rice hybrid seed production lead to un-uniformity and yield loss in hybrid rice. laborious and time consuming phenotypic evaluations are used for elimination of off-type plants in cms multiplication farms. th...

Hybrid rice has an average 15 % to 20 yield advantage over inbred lines. The availability of stable cytoplasmic male sterility system is vital for commercial hybrid rice. experiment was conducted develop japonica type CMS lines national varieties. National varieties were tested determine as maintainer, or restorer features via test cross. crosses made by using 19 and 21 1 line. All which are de...

Open source project collaboration web portals (e.g., Mozilla.org, SourceForge.net) have become the focal point for interaction with and development of most open source software projects. These collaboration portals allow considerable community interaction with a project while respecting and maintaining effective control by the project’s leaders over process, architecture, participation, and qua...

The hadronic calorimeter for the CMS experiment requires photodetection in a 4 Tesla magnetic field. This, plus high neutron radiation and a 25 ns bunch-crossing, necessitated the development of a new type of high-rate multi-channel hybrid photodiode. As our specifications became tighter, design changes in the diode structure and surface treatment became necessary, resulting in a better product...

PURPOSE To investigate the mechanisms that mediate the release of ATP induced by cyclic mechanical stress (CMS) and the role of extracellular ATP in the mobilization of arachidonic acid (AA) and prostaglandin secretion. METHODS Porcine trabecular meshwork (pTM) cells were subjected to CMS. Extracellular ATP was detected with a luciferin-luciferase assay in the presence or absence of transport...

AIMS Familial hypertrophic cardiomyopathy (HCM) is one the most common heart disorders, with gene mutations in the cardiac sarcomere. Studying HCM with patient-specific induced pluripotent stem-cell (iPSC)-derived cardiomyocytes (CMs) would benefit the understanding of HCM mechanism, as well as the development of personalized therapeutic strategies. METHODS AND RESULTS To investigate the mole...

BACKGROUND Medication nonadherence costs $300 billion annually in the US. Medicare Advantage plans have a financial incentive to increase medication adherence among members because the Centers for Medicare and Medicaid Services (CMS) now awards substantive bonus payments to such plans, based in part on population adherence to chronic medications. We sought to build an individualized surveillanc...
