Large-scale simulations of fluctuating biological membranes.
We present a simple, and physically motivated, coarse-grained model of a lipid bilayer, suited for micron scale computer simulations. Each approximately 25 nm(2) patch of bilayer is represented by a spherical particle. Mimicking forces of hydrophobic association, multiparticle interactions suppress the exposure of each sphere's equator to its implicit solvent surroundings. The requirement of hi...
متن کاملpassivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Normal Pressure Hydrocephalus Presentation with a Large Pseudomeningocele
Background and Importance: This interesting case is about the presence of normal pressure hydrocephalus and a large pseudomeningocele at the same time after 13 months of posterior fossa surgery. Although the occurrence of a pseudomeningocele following posterior fossa surgery is not so rare, such a late large pseudomeningocele development with signs and symptoms of NPH after 13 months of surgery...
متن کاملA COMPARISON BETWEEN THERMAL AND X RADIOGRAPHY FOR STUDYING THE INTERNAL STRUCTURE OF BIOLOGICAL
ABSTRACT Background: With respect to the difference in the interaction of thermal neutron and X rays with matter, using two radiography systems of thermal neutron and X rays will yield highly valuable information for studying the inner structure of biologic samples. Methods: The high sensitivity of thermal neutron to hydrogen, in particular, has led to recognizing this system as a useful tool ...
متن کاملBiological membranes
Biological membranes allow life as we know it to exist. They form cells and enable separation between the inside and outside of an organism, controlling by means of their selective permeability which substances enter and leave. By allowing gradients of ions to be created across them, membranes also enable living organisms to generate energy. In addition, they control the flow of messages betwee...
