In Nitella the protoplasm forms a layer about 15 microns thick surrounding a large central vacuole. The outer part of the protoplasm is a gel, the inner layer is a sol which is in continual motion travelling the entire length of the cell in opposite directions on opposite sides and thus making a complete circuit (cyclosis). If we have a cell devoid of motion and if we regard the protoplasm in a...

Eosinophilic inclusions in the cytoplasm of protoplasmic astrocytes of the neocortex, usually in the clinical setting of epilepsy and/or psychomotor retardation, were first recognized and illustrated by Alois Alzheimer in 1910. Traditional special stains have failed to elucidate the specific nature of these inclusions. Ultrastructurally, the material was composed predominantly of highly electro...

a modified model has been analytically developed to describe the induction time of an elliptic air bubble in contact with an elliptic hydrophobic oil droplet. the role of hydrophobicity was revealed in the slippage of liquid over the surfaces of bubble and droplet. in this condition, the analytical relationships for pressure distribution and consequently hydrodynamic resistance force through th...

Abstract In this paper interparticle potential model of the lattice Boltzmann method (LBM) is used to simulate deformation and breakup of a falling droplet under gravity force. First this model is applied to ensure that the surface tension effect is properly implemented in this model. Two tests have been considered. First, it has been checked an initial square drop in a 2D domain can freely def...

HF is a corrosive mineral acid. It has extremely harmful systemic effects through any route of exposure. In dilute solutions the onset of symptoms is latent. It is important for caregivers to remember that HF has distinct clinical signs and a specific antidote, namely calcium gluconate. The industrial use of HF heightens the importance of being prepared for possible exposures. The emergency med...

background: formalin is an aqueous solution of formaldehyde. it is a protoplasmic poison and causes coagulation necrosis and tissue fixation. case: a 19-year-old girl was brought for autopsy to the mortuary of jss medical college, mysore. conclusion: formalin is an unusual poison to be ingested for suicidal purposes due to selective availability and its strong taste and odor.
