objective: the present study was carried out to study the relationship between sensation seeking and social skills in two groups of school age patients down-syndrome (ds) and autism disorder (ds).  methods: this is a descriptive-analytic and correlation study in which all participants were of primary school age (10 to 13 years) with down-syndrome and autism disorder of autism spectrum disorder ...

background & aim: although socio-economic variables are widely used for describing the tourist's behavior, but increasing awareness is evident in current researches that personality characteristics might also be useful for that purpose. in this regard, the present study compares the personality characteristics of iranian tourists with those of non tourists. method and materials: in a causal com...

BACKGROUND AND PURPOSE Gadolinium-based contrast agents have been associated with lasting high T1-weighted signal intensity in the dentate nucleus and globus pallidus, with histopathologically confirmed gadolinium retention. We aimed to longitudinally investigate the relationship of multiple gadolinium-based contrast agent administrations to the Signal Intensity Index in the dentate nucleus and...

The globus pallidus is a nucleus in the indirect pathway of the basal ganglia circuits. Neurotensin has been reported to play an important role in the central nervous system. Functional study revealed that systemic administration of neurotensin produced antiparkinsonian effects. The aim of the present study was to investigate the effects of neurotensin on the firing rate of globus pallidus neur...

OBJECTIVES Minimal data exist to define the use of contemporary dual pH with multichannel intraluminal impedance (MII) probes integrating both pharyngeal acid and impedance sensors to evaluate laryngopharyngeal reflux (LPR) symptoms in a laryngology clinic population. This study was performed to review a series of patients tested with dual pH-MII for suspected LPR symptoms and to analyze pH-MII...

In this paper, we analyze some technical issues concerning the use of Grid-enabled technologies based on the Globus Toolkit to solve multi-objective optimization problems. We develop two distributed algorithms: an enumerative search and an evolutionary algorithm. The former is a simple technique, whose high time complexity is mastered down to acceptable execution times to some extent by the use...

The Globus Replica Catalog is a fundamental Data Grid service. It is important to evaluate the performance of this complex system, currently based on LDAP servers. The paper presents the results obtained during performance tests, which were done with three popular LDAP implementations (OpenLDAP, Oracle Internet Directory (OID), Netscape Directory) available today. Oracle9i is a new product and ...
