Transformation of inborn reaction of leg flexion into conditioned escape response of leg extension was studied. The model of the so called precise reflex was used. A dog could avoid or escape the shock applied to the paw by placing this paw in a narrow ,,safety zone" located at a definite height above the floor. When the shock is applied to the paw located below this zone, the escape response i...

Anaphylactic shock, as a kind of distributive shock, is considered as a consequence of histamine induced vasodilatation with increased vascular permeability. Tachycardia is the early warning sign of shock and bradycardia is a rare manifestation of shock. A 78 year-old woman presented with shrimpinduced anaphylactic shock with bradycardia. She was treated by beta-blocker currently and further Th...

We analyze the conditions for public debt-to-GDP ratio stability extending Domar’s approach by including interaction between government’s reaction function and private sector’s function, considering impact of 2020–2021 pandemic shock monetary fiscal policy responses, with simulations applied to Italian case. The outcomes numerical show crucial importance ECB extraordinary policies, NGEU and, le...

The parameters of combustion synthesis and shock-wave initiation reactive W/PTFE/Al compacts are investigated. Preliminary thermodynamic calculations showed the possibility system at high adiabatic temperatures (up to 2776 °C) a large proportion condensed products. effect Al content (5, 10, 20, 30 wt%) in on ignition development exothermic reactions was determined. Ignition rates were measured ...

NOL large card gap test is not suitable to assess the shock sensitivity of granular propellant beds made of large grains. The result can be strongly influenced by the heterogeneity of the bed. A new small scale gun propellant shock sensitivity test has been developed at ARDEC. This test is a sensitive discriminator to assess gun propellant shock sensitivity. INTRODUCTION Shock-to-detonation sen...

Two sets of hydrodynamic equations for a mixture of four gases undergoing a bimolecular chemical reaction are discussed. The former consists in a system of balance laws for the case of a chemical relaxation time of the same order of the macroscopic processes (slow reaction). Conversely, the latter is a system of conservation laws for the case of short chemical relaxation time (fast reaction). A...

BACKGROUND Paradoxical kinesis has been observed in bradykinetic people with Parkinson's disease. Paradoxical kinesis occurs in situations where an individual is strongly motivated or influenced by relevant external cues. Our aim was to induce paradoxical kinesis in the laboratory. We tested whether the motivation of avoiding a mild electric shock was sufficient to induce paradoxical kinesis in...

This paper examines implications of housing and household leverage on macroeconomic fluctuations under credit shocks in the presence of the zero lower bound (ZLB) on nominal interest rates. To this end, I build a housing model by incorporating houses into a standard deleveraging model and allow debt limits to be endogenous. I find that, under an adverse credit shock, only with high leverage can...

We build in this paper a numerical solution procedure to compute the flow induced by spherical flame expanding from point source at constant expansion velocity, with an instantaneous chemical reaction. The is supposed be self-similar and split three zones: inner zone composed of burnt gases rest, intermediate where regular initial atmosphere fresh rest. bounded reactive shock (inner side) so-ca...
