It is very well known that tuned mass dampers are engineered to minimise the vibrations in buildings in earthquake prone areas and in some cases machinery [1]. This paper evaluates the utility of Tuned Mass Dampers in passenger cars. For the same suspension system, addition of a tuned mass was found to reduce the transmissibility by a considerable amount. Addition of a tuned mass also helps in ...

We combine experiments, large scale simulations and continuum models to study the emergence of coherent structures in a suspension of magnetically driven microrollers sedimented near a floor. Collective hydrodynamic effects are predominant in this system, leading to strong density-velocity coupling. We characterize a uniform suspension and show that density waves propagate freely in all directi...

l-Carnitine was recently found to downregulate the ubiquitin proteasome pathway (UPP) and increase insulin-like growth factor 1 concentrations in animal models. However, the effect of l-carnitine administration on disuse muscle atrophy induced by hindlimb suspension has not yet been studied. Thus, we hypothesized that l-carnitine may have a protective effect on muscle atrophy induced by hindlim...

Hagfish slime is an ultra dilute, elastic and cohesive hydrogel that deploys within milliseconds in cold seawater from a glandularly secreted exudate. The slime is made of long keratin-like fibers and mucin-like glycoproteins that span a network which entraps water and acts as a defense mechanism against predators. Unlike other hydrogels, the slime only confines water physically and is very sus...

This article is one of three highly influential articles on the topology of manifolds written by Robert D. Edwards in the 1970’s but never published. This article “Suspensions of homology spheres” presents the initial solutions of the fabled Double Suspension Conjecture. The article “Approximating certain cell-like maps by homeomorphisms” presents the definitive theorem on the recognition of ma...

Objective(s) This study planned to assess antidepressant like activity of aqueous extract from leaves of Citrus maxima Merr. (Rutaceae). Materials and Methods Boiling was used for aqueous extraction. Acute toxicity study was performed in mice. Antidepressant activity was studied using locomotor activity test, modified forced swimming test (FST) and tail suspension test (TST). Three doses 100...

Depression is a heterogenous, multifaceted disorder with symptoms manifested at the psychological, behavioral and physiological level. Therefore, present study was designed as a model to analyze the long lasting effects of methylmercury chloride in male rats with a focus on depression like behavior. Male albino rats of Wistar strain were exposed orally to a dose of 2 mg/kg of methylmercury chlo...
