Free vibration analysis of a functionally graded porous triangular plate with arbitrary shape and elastic boundary conditions using an isogeometric approach
No full textThis paper presents a comprehensive analysis of the free vibrations of functionally graded porous (FGP) triangular plates with arbitrary shapes and elastic boundary conditions using Isogeometric Analysis (IGA). We express the triangular shapes by using non-uniform rational B-splines (NURBS). The impact of porosity, geometry, and boundary conditions on the natural frequencies is investigated, with a focus on three key factors: porosity coefficient, geometric shape, and type of boundary conditions. Results show that increasing porosity generally leads to an increase in natural frequencies for thin plates, while thicker plates exhibit the opposite trend. The effect of geometric shape, characterized by different angles, is investigated and reveals distinct trends in natural frequencies. The study also investigates both classical and elastic boundary conditions, illustrating the impact of arbitrary boundary conditions on the natural frequency response. Validation against previous references and finite element methods establishes the accuracy of the presented results. The paper concludes with an extension of the analysis to various scenarios, offering valuable insights into the intricate interplay of porosity, geometry, and boundary conditions on the vibrational behavior of FGP triangular plates
Neuroprotective Effects of Exercise on Binge Alcohol-Induced Brain Damage
No full textBinge alcohol damages the brain. Exercise is known to enhance brain health, and we have previously shown that exercise counteracts binge alcohol damage. The present study investigates possible mechanisms, including increased exerkines (peripherally-derived factors that sustain the brain), decreased stress hormone (cort) output, and decreased neuroimmune response to binge alcohol. Rats were given a single dose of alcohol (5 g/kg or isocaloric control diet) once per week for five weeks. Half of the animals exercised, and half remained sedentary. Homecage behavior was recorded the morning after each alcohol dose. After 5 weeks, brain tissue and blood-borne factors were assessed. We found that exercise significantly increased body weight in males but not females, and overall, binged animals ran less than control animals. There were no effects of exercise on alcohol-induced cort output or levels of adiponectin (an exerkine). Binge alcohol increased, and exercise decreased neuroimmune response. Home cage behavior analysis showed that binged rats spent less time grooming than controls, and exercise eliminated this effect. Home cage binge animals grooming less than control suggesting a state of malaise. In conclusion, exercise buffers the effects of binge alcohol, both neurally and behaviorally. Ongoing studies continue to probe potential mechanisms, including the contribution of additional exerkines and analysis of gene transcription changes induced by binge alcohol and/or exercise.Psychology, Department ofHonors Colleg

Iranian terms for footwear and their naming
No full textInternational audienceVarious motivations can be found behind the naming of ‘shoe’ in Iranian languages,such as terms related to ‘foot’, ‘leather’, ‘wood’, ‘to hold’, and ‘covering’. This had ledto different shoe names in New Iranian languages (after 900 CE).Old Iranian languages (until 400 BCE), Young Avestan among them, contain shoe termssuch as aoθra- ‘shoe’ and derivations of Old Iranian *mauk- ‘to clothe’. Old Iraniancontact languages such as Akkadian exhibit words referring to ‘shoe’ which resembleIndo-European terms for the foot, e.g. Akkadian patû ‘shoe’. The name of the shoe inElamite, one of the main Old Persian contact languages, is still unknown, however,Elamite may refer either to a shoe or an envelope (Walther Hinz & HeidemarieKoch).Middle Iranian languages (300 BCE–700 CE) contain diverse data related to shoes suchas derivations of Old Iranian *kap- ‘to take, to hold’, and forms such as the InscriptionalMiddle Persian surgar ‘shoemaker’. It is remarkable, however, that during the MiddleIranian period Iranian shoe terms appeared as Wanderworts in all Iranian contactlanguages—forms of the two Middle Persian words mōg (muk, muz, muc) and kafšaghave been documented in almost all non-Iranian languages which were in contact withMiddle Iranian languages.What are the reasons for these widespread borrowings? The easiest answer would betrade, yet this story seems to have a more complex justification which archaeology,linguistics, anthropology, and religious studies may shed light on. For example, beingbarefoot is one of the worst sins according to Zoroastrian Middle Persian texts. It is thuspossible that Zoroastrianism, which had become the state religion during the Sasanianperiod (224–651 CE), had an influence on the shoe industry at that time.This presentation intends to collect and etymologically comment on all shoe terms inOld and Middle Iranian languages. Moreover, it will elaborate on the reasons for thewidespread borrowing of Middle Iranian shoe terms in the whole of West Asi
