A modal-based model of milling machine tools subjected to time-periodic nonlinear cutting forces is introduced. The model describes the phenomenon of bistability for certain cutting parameters. In engineering, these parameter domains are referred to as unsafe zones, where steady-state milling may switch to chatter for certain perturbations. In mathematical terms, these are the parameter domains...

Sensory input is pervasive among motor networks and continuously adapts motor patterns to changing circumstances. To elucidate common principles of sensorimotor integration, it is beneficial to characterize sensory influences on motor network operation and compare these influences between species. To facilitate such comparison, we have studied the influence of the anterior gastric receptor (AGR...

Distinct motor patterns are selected from a multifunctional neuronal network by activation of different modulatory projection neurons. Subsets of these projection neurons can contain the same neuromodulator(s), yet little is known about the relative influence of such neurons on network activity. We have addressed this issue in the stomatogastric nervous system of the crab Cancer borealis. Withi...

A lung function study was carried out to determine the relative effect of rice husk and saw dust on mill workers. The study consisted of 195 subjects of which 56 rice mill workers, 71 saw mill workers and 68 controls of similar age, sex and socio-economic condition. FVC was significantly reduced in saw-mill workers compared to both the controls and rice mill workers. Both FEV1 and PEFR/min were...

Abstract The Crookes radiometer (also known as a light mill) is fascinating sunlight-powered device, in which set of vanes placed inside glass bulb within partial vacuum has been pulled. then rotate when sunlight shines on the bulb. reason for turning was subject to intense debate and many students still have an incorrect understanding device. We analyse forces involved much less well-known (ca...

A novel device is described for efficiently harvesting bone marrow in bone marrow transplantation that uses a newly developed passive flexible drilling unit and suction mechanism. The device reduces the invasiveness of bone marrow harvesting by collecting stem cells from the iliac bone with minimal punctures and by reducing the operation time and the contamination by T cells. The device is inse...

The hyperpolarization-activated inward cationic current (Ih) is known to regulate the rhythmicity, excitability, and synaptic transmission in heart cells and many types of neurons across a variety of species, including some pyloric and gastric mill neurons in the stomatogastric ganglion (STG) in Cancer borealis and Panulirus interruptus However, little is known about the role of Ih in regulatin...

This paper presents an experimental approach to study the phenomena of segregating water and gravel using a large ball mill device that reproduces segregation under debris flow. First, experiment was conducted in various conditions: mixing, bed velocity, laid roughness. The occurrence conditions mixing are categorized compared with each other and/or without roughness on bed. Furthermore, moveme...
