Differential scanning calorimetry - Wikipedia
Differential scanning calorimetry - Wikipedia

Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. Generally, the temperature program for a DSC analysis is designed such ...

Service robots must comply with very demanding ,safety, requirements in order to guarantee that a human can be assisted without any risk of injury. This paper presents a detailed multibody model of the interaction between a single link manipulator and a human head–neck to study the different and more significant parameters involved in the design of the manipulator.

The unique ,properties, of hybrid organic–inorganic perovskites (HOIPs) promise to open doors to next-generation flexible optoelectronic devices. Before such advances are realized, a fundamental understanding of the ,mechanical properties, of HOIPs is required. Here, we combine ab initio density functional theory (DFT) modeling with a diverse set of experiments to study the elastic ,properties, of ...

experimental, study investigated the ,mechanical, and physical ,properties, of concrete specimens produced by replacing natural coarse aggregate with barite aggregate at 0, 10, 20, 30, 40 and 50% by volume. Furthermore, the thermal conductivity coefficients of the concretes were calculated, which were obtained by increasing the barite

The simulated intracranial pressure together with the ,experimental, results are shown in Fig. 5, where the ,helmet, in the helmeted head model had a carbon reinforced polyester shell and a foam liner that has a density of 80 Kg/m 3 and a thickness of 10 mm. Relative reductions in the intracranial pressure at the coup and contrecoup side by the ,helmet, are provided in Table 4.
