In this work, several machine learning techniques are presented for nanofiltration modeling. According to the results, specific errors are defined. The rejection due to Nanofiltration increases with pressure but decreases with increasing the concentration of chloride ion. Methods of machine learning represent the rejection of nanofiltration as a function of concentration, pH, pressure and also ...

Objective: Among the various impression materials, for alginate tear strength is probably more important than the compressive strength. The tear strength is important when an impression involves a mechanical undercut and/or lacks bulk strength to resist tearing. This study evaluated tear strength of Iralgin and compared it with tear strength of Alginoplast. Methods: In this invitro experime...

a vermiform specimen taken from a 10-year-old boy patient with the chief complain of sneezing, coughing and nasal dis-charge with a history of consumption of fast snack in the day before and liver of sheep in two weeks ago was referred for diagnosis to the helminth taxonomy laboratory, dept. of mdical parasitology and mycology, school of public health, tehran university of medical sciences, ira...

Background: Monitoring of phenotypic characteristics of T-lymphocytes in peripheral blood is commonly performed to give the clinical parameters in the management of kidney transplant recipients.   Objective: To predict rejection in renal transplantation by immune parameters. Methods: 16 non-diabetic kidney transplant candidates (4 females and 12 males, age = 20-65 yr, first time transplant) wer...

BACKGROUND Quantification of proteinuria (albuminuria) in renal transplant recipients is important for diagnostic and prognostic purposes. Recent guidelines have recommended quantification of proteinuria by spot protein-to-creatinine ratio (PCR) or spot albumin-to-creatinine ratio (ACR). Validity of spot measurements remains unclear in renal transplant recipients. METHODS Systematic review of...

Purpose: Blinded independent central review (BICR) is advocated by regulatory authorities as a means of minimizing bias and independently verifying endpoints based on medical imaging when the data is intended to support pivotal trials. However, discordance between reviewers at the BICR raises concern with regulators. There are few published metrics related to discordance rates at the BICR and t...

The use of frequency-shift (FRESH) filtering for the rejection of adjacent channel interference (ACI) in GMSK modulated VLF communications is investigated in the presence of impulsive noise. The effects of such filtering in conjunction with a simple “holepunching” technique for removing impulses from the signal are characterised. A range of scenarios based on a high powered GMSK interferer (10 ...

early wound excision and grafting of burn wounds is regarded not only as the method of choice in speeding up the healing process in deep burns, but also limits contracture and infection, on the other hand, smoking has generally been implicated in the delay of the healing process in a variety of surgical procedures, in this study we report the outcome of a cross-sectional study of all the 395 me...
