When a fish or a reptile changes color, it is because of the movement of tiny pigment granules in specialized skin cells called melanophores. These cells have hundreds of membrane-bound pigment granules, or melanosomes, which can be aggregated at the center of the cell or dispersed throughout the cytoplasm. When the melanosomes are aggregated the animal appears lighter, and as they disperse the...

Classical Turkish poetry is important in terms of reflecting the cultural and sociological structure Ottoman society together with different images dreams texts. Places that symbolize general characteristic a nation have also been main material poems. In texts which Divan put love at center, idols, one objects beauty, are among them, when they use concrete signs their depictions beloved, actor ...

the crankshaft is one of the most critically loaded components as it experiences cyclic loads in the form of bending and torsion during its service life. its failure will cause serious damage to the engine so it’s important at the time of design to verify fatigue strength. more challenges in crankshaft design due to increasing vehicle payloads, lower weight requirement, higher efficiency and lo...

Beauty has been an intriguing issue since the evolving of a culture in mankind. Even the Neanderthals are believed to have applied makeover to enhance facial structures and thus underline beauty. The determinants of beauty and aesthetics have been defined by artists and scientists alike. This article will give an overview of the evolvement of a beauty concept and the significance of the facial ...

In Bradley ([2011b]), I offered an analysis of Sleeping Beauty and the Everettian interpretation of quantum mechanics (EQM). I argued that one can avoid a kind of easy confirmation of EQM by paying attention to observation selection effects, that halfers are right about Sleeping Beauty, and that thirders cannot avoid easy confirmation for the truth of EQM. Wilson ([forthcoming]) agrees with my ...

Artemisinin derivatives are essential for the treatment of Plasmodium falciparum malaria throughout the world. Given orally, artesunate and artemether—the 2 main compounds—are rapidly absorbed and metabolized to dihydroartemisinin (DHA), the metabolite responsible for the majority of the parasitocidal activity. The precise mechanism of action is still debated , but the main properties of this c...

In this study, the dynamic behaviour of a beam carrying accelerating mass is investigated. A MATLAB code was developed for numerical solutions. The accelerating moving mass that is travelling on the beam was modelled as a moving finite element in order to include inertial effects beside gravitation force of mass. Since the mass moves along the deflected curve of the beam, these effects are, res...
