The dependences of the spectra radiation-induced attenuation (RIA) light in a pure-silica core (PSC) optical fiber (OF) during and after gamma-irradiation up to 590 kGy at dose rate 7.6 Gy/s near infrared range have been investigated. It was shown that starting with an absorbed ~100 kGy, RIA 1550 nm becomes larger than 1310 due increase long-wavelength (LWL) RIA. absorption band, maximum wavele...

This study was conducted to describe the minimum detection limit, reproducibility, accuracy, specificity and parallelism of different pregnancy-associated glycoprotein radioimmunoassay (PAG-RIA) systems: RIA-497, RIA-706, RIA-780, RIA-809 and RIA-Pool. Their ability to distinguish between non-pregnant and pregnant females at day 30 after artificial insemination (AI) was investigated. The antise...

The 125I-radioimmunoassay (RIA) for benzylecgonine (cocaine metabolite) in urine was evaluated by comparison with gas-liquid chromatography (GLC) and thin-layer chromatography (TLC) and the Enzyme-Multiplied Immunoassay Technique (EMIT). By RIA, a statistically significant concentration, 2 microng/liter, was observed for urinary benzoylecgonine. The coefficient of variation for the RIA was 2.58...

This paper is aimed at proposing a new approach to Reliability-based Design Optimization (RBDO) and applying it cushioning packaging design with highly nonlinear system. The problem formulated as an RBDO problem, which included minimizing cost function probabilistic constraints. Here, the thickness of cushion material dealt uncertainty uncontrolled parameters. traditional reliability index (RIA...

This study compares cyclosporin A (CsA) concentrations in plasma from patients receiving various transplants, as measured by HPLC and RIA with a monoclonal antibody for CsA and an 125I-labeled ligand. The RIA was restandardized with in-house standards because it overestimated CsA by an average of 23%. The RIA was sensitive to 2 micrograms/L, the standard curve was linear from 20 to 500 microgra...

A solid-phase radioimmunoassay (RIA) procedure was compared with the indirect fluorescent antibody (IFA) test in a serological study of 76 female adults with urinary tract infections. Relative serum antibody activity was determined against patients' homologous infecting enterobacteria by RIA and IFA and against heterologous enterobacterial common antigen (Escherichia coli O14) by RIA. There was...

One of the main reasons for the success of Web 2.0 is the improvement in user experience. This improvement is a consequence of the evolution from HTML User Interfaces (UI) to more usable and richer UI. The most popular Web 2.0 applications have selected the Rich Internet Application (RIA) paradigm to achieve this goal. However, the current Web Engineering methods do not provide the expressivity...

Through retrospective review of consecutive charts, we compare the short-term and long-term clinical outcomes after robotic-assisted right colectomy with intracorporeal anastomosis (RIA) (n=89) and laparoscopic right colectomy with extracorporeal anastomosis (LEA) (n=135). Cohorts were similar in demographic characteristics, comorbidities, pathology, and perioperative outcomes (conversion, days...

We compared the clinical values for diagnosis of acute pancreatitis of two commercial assays for pancreatic elastase: an ELISA procedure with monoclonal antibodies and a RIA technique with polyclonal antibodies. In 14 patients with acute pancreatitis, serum concentrations of elastase determined by ELISA (ELISA-elastase) decreased much faster (half-life 0.4 days) than those of elastase determine...
