Mechanics of axonal force generation in embryonic Drosophila neurons in vivo
… years it has become increasingly evident that mechanical stimuli play an important role in the differentiation, growth, development, and motility of cells. Neurons in particular have been shown to be highly sensitive to a variety of mechanical inputs. For example, it has been shown that …

Stretch induced hyperexcitability of mice callosal pathway
… nervous system plasticity is also sensitive to mechanical stretch. This is important, given the host of clinical conditions involving changes in mechanical tension on the brain, and the normal role that mechanical tension plays in brain development. A novel platform is developed to investigate …

Efeito da hidrogenação catódica em ausência de tensão mecânica e durante ensaios de corrosão sob tensão em aços martensíticos
… cathodically charged, in the absence of applied mechanical tension, in a 1N H2 SO4 solution, free from poisons, to observe their tendency to crack. The "crack index" was larger for the AISI 4340 than for the AISI 8640 and at low applied current densities this difference was very marked. The …

Neurons under tension: A study of vesicle dynamics
… Growing experimental evidence suggests that mechanical tension plays a significant role in determining the growth, guidance, and function of neurons. Recent developments in experimental techniques have made quantitative studies at the level of individual cells possible. The purpose of this …

Computational Studies on the Mechanical Properties of Muscle and Blood Clot Elasticity
Mechanical proteins perform a vital role in cells by transmitting and bearing mechanical forces involved in cell growth, locomotion, and adhesion. Little is known at the molecular level that explains how such proteins are capable of reversibly stretching, in some cases to twice their resting …

Axon Guidance Autonomy and Tensional Requirement for Synaptic Function: Is Learning a Forced Response
… if held by a micropipette that resupplies mechanical tension, the growth cones' ability to localize synaptic vesicles is restored. Our results demonstrate functional autonomy of axonal growth cones as they navigate and initiate synaptogenesis, while implicating intercellular tension as a …

CENTRIFUGALLY TENSIONED METASTABLE FLUID DETECTORS FOR DETECTION OF ALPHA, NEUTRON, AND OTHER SIGNATURES OF SPECIAL NUCLEAR MATERIALS IN NUCLEAR WASTE REPROCESSING FACILITIES
… made to the technology of Centrifugally Tensioned Metastable Fluid radiation Detectors (CTMFDs) as well as potential application to nuclear waste reprocessing facilities. The CTMFD operates by stretching a fluid below vacuum pressure using centrifugal mechanical tension to destabilize the …

Polyethylene-montmorillonite nanocomposites
… possibility of global property improvement – mechanical strength, toughness, electrical breakdown strength, electrical erosion resistance and flame retardancy. In order to disperse montmorillonite clay (MMT) into polyethylene(PE), the clay sheets need to be rendered organophilic. Masterbatches …

Does Blood Flow Restriction Applied Post High-Load Exercise Augment Skeletal Muscle Growth Following Eight Weeks of Training?
… can augment muscle growth independent of further mechanical tension, specifically when maintained post high-load training. Thirteen untrained individuals performed 24 training sessions. The control arm performed one set of elbow flexion (70% 1RM) exercise to volitional fatigue, while the …

Physics of Self-assembly in Complex Matter
… avalanches (abrupt release of accumulated mechanical tension) in actomyosin. In the fourth section, I use deep learning to identify substructures in the global three-dimensional (3D) folded structure of genomes inside the cell nucleus. Those 3D substructures were originally detected by the …

Surface Orientation Dependent Corrosion Damage and Temperature Dependent Mechanical Property Degradation of Sensitized AA5083-H116 Alloys
… to its resulting corrosion resistance and mechanical performance. Alcoa 5083-H116 was sensitized in an environmental chamber at 100°C for up to ~1500 hours and 150°C up to ~2000 hours, revealing different degrees of sensitization based on exposure times. Microstructural characterization was …
