background: attention deficit hyperactivity disorder (adhd) is a common psychiatric disorder among children and adolescents that can be continued into adulthood in 30 to 50% of cases. adult adhd disorder can affect the performance of an individual and may predispose to drug abuse, alcoholism, smoking, sexual offenses, violation of law, educational and other social problems. the coincidences of ...

it is shown that when a special vertex stretching is applied to a graph, the cochordal cover number of the graph increases exactly by one, as it happens to its induced matching number and (castelnuovo-mumford) regularity. as a consequence, it is shown that the induced matching number and cochordal cover number of a special vertex stretching of a graph g are equal provided g is well-covered bipa...

purpose: to evaluate the effect of vertical prism induced stress on binocular visual evoked potentials. methods: using checkerboard stimulus patterns in two spatial frequencies (sfs) of 0.48 cpd as a low sf and 2.18 cpd as a moderate sf reversing with temporal frequency of 4 hz, the effect of increasing visual stress using vertical prisms of 0, 1, 2 and 3 prism diopters on binocular visual evok...

the present study has been directed to investigate ursodeoxycholic acid (udca) effect in children, to reduce the high liver transaminases induced by anticonvulsant drugs (drug induced hepatitis). this idea has been driven from cytoprotective and antioxidant properties of udca to be used in drug induced inflammation in liver. twenty two epileptic patients aged between 4 mo - 3 yr whom were under...

this paper presents a method for diagnosis of eccentricity fault in a switched-reluctance motor (srm) during offline and standstill modes. in this method, the fault signature is differential induced voltage (div) achieved by injecting diagnostic pulses to the motor windings. it will be demonstrated by means of results that there is a correlation between differential induced voltage and eccentri...

common vetch ( vicia sativa l.) an annual forage, belonging to the fabaceae family is one of the highly cultivated forage legumes in iran. drought stress is a serious adverse factor that limits plant growth and productivity, inducing a range of physiological as well as biochemical responses in plants. it may also lead to generation of oxygen activated species which in turn result in cell destru...

conclusions hepatotoxicity of halogenated inhalational anesthetics has been well documented in available literature. halothane-induced liver injury was extensively acknowledged; however, the next generation halogenated anesthetics have different molecular structures and associated with less hepatotoxicity. although anesthesia-induced hepatitis is not a common occurrence, we must consider the as...

background hearing capability plays a principal role on human's communication. noise-induced hearing loss (nihl) caused by exposure to high noise levels is a serious socio-economic problem in modern societies. nihl can either be reversible, resulting in a temporary threshold shifts (tts) or irreversible, resulting in a permanent threshold shifts (pts). pts is often confirmed in the time span of...

background: contrast nephropathy will increase mortality up to 30% following angiographic procedures. adenosine is a crucial mediator of contrast-induced nephropathy. the purpose of this study was to investigate whether the adenosine antagonist theophylline reduces the incidence of cn after coronary angiography. methods: in this randomized, double-blind, placebo-controlled clinical trial study,...

a long-standing debate among the vocabulary researchers is the depth of processing to learn vocabulary. this paper is a quantitative research which considers a revision in the “involvement load hypothesis” proposed by laufer and hulstijn in 2001. it investigates the role of proficiency and evaluation in this hypothesis in order to better reveal its potential contribution to vocabulary learning....
