introduction: newborn hearing screening leads to the early detection of hearing impairment. the aim of screening is to decrease or remove the effect of hearing impairment on development of speech and language by timely diagnosis and effective treatment. a number of risk factors lead to delayed start of decreased hearing ability including: 1. congenital infection with cytomegalovirus  (cmv) viru...

in the present work, the modified nickel electrode was electrochemically fabricated and tested for the electro-oxidation of paracetamol in alkaline media. the methods of cyclic voltammetry (cv), chronoamperometry (ca), and impedance spectroscopy (eis) were used to determine kinetic parameters such as transfer coefficient (α), the catalytic reaction rate constants (k), and the diffusion coeffici...

the present study was designed to develop a simple, validated liquid chromatographic method for the analysis of azithromycin in bulk and pharmaceutical dosage forms using ultraviolet detector. the best stationary phase was determined as c18 column, 5 µm, 250 mm × 4.6 mm. mobile phase was optimized to obtain a fast and selective separation of the drug. flow rate was 1.5 ml/min, wavelength was se...

detecting anomalies is an important challenge for intrusion detection and fault diagnosis in wireless sensor networks (wsns). to address the problem of outlier detection in wireless sensor networks, in this paper we present a pca-based centralized approach and a dpca-based distributed energy-efficient approach for detecting outliers in sensed data in a wsn. the outliers in sensed data can be ca...

intrusion detection in wireless networks has been a challenging researchproblem in network security for more than half a century. this paper presents anovel intrusion detection method based on received signal strength acceptancetest (rssat) to improve the ids capabilities in anomaly-based host-basedintrusion detection systems (hids). the new system can identify suspiciousbehaviors detecting ano...

background: alcohol dependence (ad) is a major reason for morbidity and visits to emergency medical settings. however, the detection of ad is often difficult or overlooked. this study aimed to develop a brief screening questionnaire in hindi language for detection of ad in an emergency medical setting. methods:  the authors in consultation devised a set of questions related to ad in the hindi l...

glutaric acidemia, type i (ga i), was first described in 1975. the disease is caused by a genetic deficiency of the enzyme, glutaryl-coa dehydrogenase (gcd), which leads to the buildup of glutaric acid in the tissues and its excretion in the urine of affected patients. gcd is involved in the catabolism of the amino acids, lysine, hydroxylysine, and tryptophan. over 200 cases of ga i have been r...

background and objectives: contamination of cell lines and biological products is one of the major problems of cell culture techniques. rapid detection of mycoplasma contamination in cell culture is an important part of quality control standards in related laboratories. the aim of this study was to evaluate the efficacy of pcr in detection of myroplasma as contaminants in cell cultures and othe...
