We start by establishing the result for an elementary triangle: one whose vertices are lattice points and which contains no other lattice points either in its interior or boundary. Pick’s theorem for such a triangle simply asserts that it has area 1/2, or 0 in the degenerate cases where it is flat. Given two vectors A and B, we can consider them as defining the linear transformation of the plan...

Context: Only a small proportion of knowledge and skills acquired during faculty development is actually applied on the job, leading to poor transfer of training. This results in wastage of training efforts. The present study was designed to predict the intention to transfer after participation in a faculty development workshop using theory of planned behavior (TPB). Methods: A questionnaire wa...

[Purpose] This study investigated the effects of craniocervical flexion exercise on upper-limb postural stability by measuring upper-limb postural tremor during a goal-directed pointing task. [Subjects and Methods] Twenty-four subjects were randomly assigned to the exercise or control group. The exercise group performed craniocervical flexion exercise four days per week for five weeks. Upper-li...

screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. actinomycetes have the capability to synthesize manydifferent antibiotics. a total of 69 actinomycete isolates were recovered from soil samplescollected from alborz province. selected colonies (rough, chalky) of actinomycetes werepurified. all screened isolates were iden...

the antioxidant activities of methanol (me), ethanol (ee), water (we) and ethyl acetate (eae) extracts of four inula helenium l. taxa (i. helenium ssp. orygalis (boiss.) grierson, i. helenium ssp. pseudohelenium grierson, i. helenium ssp. turcarasemosa grierson and i. helenium ssp. vanensis grierson) were investigated. the phosphomolybdenum assay, β-carotene–linoleate bleaching and dpph radical...
