A case of acute silicosis complicating as spontaneous pneumomediastinum, bilateral pneumothorax and subcutaneous emphysema is described in a 35-year-old male engaged in stone crusher unit. Diagnosis was established on clinical and radiological assessment and supported by occupational history of the patient. This case is unique one as all these 3 complications at the same time are very uncommon ...

olive oil extraction methods and technology can affect the quality and quantity of the extracted oil. in this study, qualitative and quantitative parameters were investigated for oil extracted using a hammer crusher at 720 and 1450 rpm at 30°, 40°, 60° c mixing temperatures. the data were analyzed using a complete randomized block factorial design using spss software with three replications. th...

We present the Crusher system for autonomously navigating complex off-road terrain. In this paper, we describe the Crusher system’s three-pronged approach for safely and reliably moving between widely-spaced waypoints. First, the system automatically interprets aerial map data to assess mobility risk and plans trajectories that move from way point to way point. Second, the system uses a ladaran...

UNLABELLED Bioinformaticians are tackling increasingly computation-intensive tasks. In the meantime, workstations are shifting towards multi-core architectures and even massively multi-core may be the norm soon. Bag-of-Tasks (BoT) applications are commonly encountered in bioinformatics. They consist of a large number of independent computation-intensive tasks. This note introduces PAR, a scalab...

The purpose of the study is to substantiate parameters a mini crusher-shredder for processing coarse feed stalks in farms. feasibility using conditions farms and with small number animals, which has rotary-type shredder that combines operations grinding crushing, justified. research uses laws rules mathematical statistics, planning experiments, methods given existing regulatory documents. Exper...

The crushing equipment is characterized by a significant energy-consuming system during the workflow. current trend in development of such processes puts forward requirements for new or improvement existing energy-saving equipment. essence solution to problem this work determined using resonant modes, which are inherently most effective. practical implementation resonance mode has been achieved...

The article briefly analyses the explosion and fire hazard properties of coal dust different dispersions. It is emphasised that many experts working in field protection industrial safety pay insufficient attention to changes when reducing its dispersity. suggested develop a new, complex methodology based on dispersed composition dust. authors suggest put methods special sample preparation dispe...

A dynamic model of the working mechanism a compound pendulum jaw crusher with clearance is established by Lagrange multiplier method (LMD) based on L-N contact force and modified Coulomb friction model. The correctness verified MATLAB Adams comparison simulation, best selection range driving speed size determined according to laminating crushing theory (LCT). effects shock chaos phenomenon in a...
