Primary non-Hodgkin's lymphoma of the cranial vault is extremely rare. This case report presents a 42-year-old man with a painless subcutaneous scalp mass which extended intracranially associated with recent mild headache. Initial computed tomography and magnetic resonance imaging revealed two lesions emanating from the skull. Biopsy revealed a diagnosis of(More)
Recommender systems are helpful tools which provide an adaptive Web environment for Web users. Recently, a number of Web page recommender systems have been developed to extract the user behavior from the user's navigational path and predict the next request as he/she visits Web pages. Web Usage Mining (WUM) is a kind of data mining method that can be used(More)
This paper describes the design of robust control of PI/Backstepping for the snake robot to control the joints motion. First, the stability of the method is proved and, by applying this controller to the robot, its motion pattern is controlled in a way that it can move and follow by mimicking the motion of real snakes on the predefined trajectories. Then,(More)
Surface hydrophobicity is one of the most important chemical properties of carbon nanotubes which causes a wide range of materials and compounds adsorption on the surface of these nano structures. In this work, by considering this characteristic of carbon nanotubes, their ability in adsorption of cephalosporins antibiotics from aqueous solution has been(More)
INTRODUCTION Menopause is one of the most important crises in the life of women. The control of menopause symptoms is a main challenge in providing care to this population. So, the aim of present study was to investigate the effect of education through support -group on early symptoms of menopause. METHODS In this randomized controlled clinical trial 124(More)
A simple cyanide chemosensor tetranitrile compound 1 was designed and synthesized via an efficient method in the presence of nanoporous SBA-Pr-NH2 as the catalyst. The chemosensor exhibited high selectivity and sensitivity for detecting CN¯ among different anions through a visual color change from light yellow to purple. The results confirmed that the(More)
BACKGROUND Proteins necessary for DNA replication and normal regulation for the cell cycle include minichromosome maintenance-2 (Mcm-2). Overexpression of this protein in several premalignant and malignant lesions has been observed. In this study, the diagnostic value of Mcm-2 expression in distinguishing histologically-proven normal oral mucosa (NOM), oral(More)
In order to study the response of maize genotypes against the application of peat based liquid humic fertilizer. The Experiment was conducted as Split Plot in the form of randomized complete block design with three replications. The main factor included two conditions (with the application of humic fertilizer; without humic fertilizer) and the sub factor(More)
The configuration of asphaltenes on the water-oil interface was evaluated from a combination of molar mass, interfacial tension, drop size distribution, and gravimetric measurements of model emulsions consisting of asphaltenes, toluene, heptane, and water. Molar mass measurements were required because asphaltenes self-associate and the level of(More)
Optical properties of zigzag and armchair graphyne nanoribbon (GNR) sheet were investigated. Effect of increasing the width of nanoribbon on optical properties and optical band gap in particular was also studied. Calculations were based on density functional theory (DFT) and the results showed that these structures were semiconductors with the optical band(More)
