Coal and gas outburst is a dynamic disaster that poses a significant threat to coal mines. Energy analysis is an effective tool for understanding the mechanisms behind such outburst. The energy sources and dissipation during outbursts were explored using a multifunctional test system, and the energy transformation relationship was analyzed based on …
Powder crushing is the process of reducing solid material's size through mechanical forces. Various mechanisms can achieve this, including compression, impact, …
The most common injury type in crushing-compressing mechanism was tendon laceration+vessel and/or nerve injury+fracture (35.1%). The most common type of injury in cutting-crushing type mechanism was tendon lacerations+fracture (33.9%). Burns caused tissue defects (Table 2).
MECHANISMS OF INJURY INTRODUCTION Trauma starts with the transfer of energy to the body from an outside force. The transfer of kinetic energy may be blunt or sharp in nature. In addition to blunt and sharp mechanisms, there is the situation of thermal energy in the form of heat, cold, or chemical agent, which generates the heat or cold. With the
In the present study, the effects of rock types and crushing mechanisms on the morphology of manufactured sands were investigated. Three rock types, i.e., granite, conglomerate rock, and limestone, and two crushing …

The introduction of the first antipsychotic drug, chlorpromazine, was a milestone for psychiatry. The authors review the history, classification, indications, mechanism, efficacy, side effects, dosing, drug initiation, switching, and other practical issues and questions related to antipsychotics. Classifications such as first-generation/typical versus second …
Similar mechanisms were classified in the same groups, and the mechanism of injury was matched with type of injury often caused by this mechanism. In the classification of injuries, the tissues ...
smaller sizes. Depending upon the feed and product particle size, the crushing operation can be classified as follows: 1. Primary crushing: The feed material is usually the run of mine. 2. Intermediate crushing or secondary crushing: The feed material is usually product of a jaw crusher. 3. Fine crushing or coarse grinding:

crushing mechanisms on the morphological characteristics are important issues for the production and application of manufactured sand. The study of sand morphology originated from two dimensions and gradually developed into three dimensions (Zhu et al., 2014).
5.1.3 Crushing mechanisms and product size distributions. The crushing action of a crushing machine is described most usefully through the classification - breakage cycle model. The …
They observed three mechanisms of brittle collapse from the series of static and dynamic compression tests conducted, which are (1) the progressive end-crushing mode I was stable, while the other two failure modes were unstable; (2) local tube-wall buckling mode II; and (3) mid-length collapse mode III.
