Multipolar Neuron

The nervous system of all vertebrates is built up of long conducting, specialized cells, termed neurons. In order to function, these neurons, or nerve-cells, must be linked together in chains or arcs. Each neuron in the chain or arc is structurally separated from other neurons by a break termed a synapse. The structural elements of a neuronic arc are, therefore, as follows: 1.A sensitive receiving organ—the receptor or sense-organ.2.A centrally conducting receptor bipolar neuron.3.One or more short connector or internuncial neurons.4.A peripherally conducting effector multipolar neuron.5.An effector apparatus—for example, a muscle or a gland.

IN a previous paper (Bullock, Clancey and Fleischhacker, 1951) an attempt was made to separate schizophrenic reaction syndromes, due to diagnosable and often successfully treatable disease of known etiology, from idiopathic or cryptogenic schizophrenia. It was shown that the criteria of idiopathic schizophrenia are—(1)Positivey : (a) Mentally, the classical symptoms of inadequacy and inappropriateness : of thought (paralogia), of affect (parapathema), to which one may add of volition (paraboulema), usually accompanied by hallucinations, paranoid ideas, etc.(b) Physically, a slightly pathological C.S.F., due essentially to an increase of the globulin fraction.(2)Negalively : the absence of generally acknowledged organic disease of the brain, or any physical disease which is known to produce such disorders of the central nervous system or the C.S.F., as mentioned under (i).

Two conditions greatly encourage the folk use of plants to cure diseases and alleviate ailments: ∘ plant biodiversity (the richer the better)∘ particular cultural traits of local populations.Where these conditions are met, local scientific advancement may result from experimentation with and elaboration of folk remedies. Unfortunately, little scientific research has been done on South American plants that may be useful in the treatment of central nervous system (CNS) disturbances.

Valuable Method

Introduced in 1933, Sakel's pharmacological shock treatment [Sakel (1935a,1935b,1938)] is now regarded as a valuable method of treatment in schizophrenia. The complications which may ensue during the treatment are, however, both numerous and dangerous, and may be classified according to the system predominantly affected as follows:(1)The Respiratory System.(2)The Cardiovascular System.(3)The Nervous System.

AbstractThis paper deals with a possibility to use the ground-based method of observation in order to solve basic problems connected with the solar corona research. Namely:1.heating of the solar corona2.course of the global cycle in the corona3.rotation of the solar corona and development of active regions.There is stressed a possibility of high-time resolution of the coronal line photometer at Lomnický Peak coronal station, and use of the latter to obtain crucial observations.

AbstractThe occurrence of LDE-type flares in the last three cycles has been investigated. The Fourier analysis spectrum was calculated for the time series of the LDE-type flare occurrence during the 20-th, the 21-st and the rising part of the 22-nd cycle. LDE-type flares (Long Duration Events in SXR) are associated with the interplanetary protons (SEP and STIP as well), energized coronal archs and radio type IV emission. Generally, in all the cycles considered, LDE-type flares mainly originated during a 6-year interval of the respective cycle (2 years before and 4 years after the sunspot cycle maximum). The following significant periodicities were found:• in the 20-th cycle: 1.4, 2.1, 2.9, 4.0, 10.7 and 54.2 of month,• in the 21-st cycle: 1.2, 1.6, 2.8, 4.9, 7.8 and 44.5 of month,• in the 22-nd cycle, till March 1992: 1.4, 1.8, 2.4, 7.2, 8.7, 11.8 and 29.1 of month,• in all interval (1969-1992):a)the longer periodicities: 232.1, 121.1 (the dominant at 10.1 of year), 80.7, 61.9 and 25.6 of month,b)the shorter periodicities: 4.7, 5.0, 6.8, 7.9, 9.1, 15.8 and 20.4 of month.Fourier analysis of the LDE-type flare index (FI) yields significant peaks at 2.3 - 2.9 months and 4.2 - 4.9 months. These short periodicities correspond remarkably in the all three last solar cycles. The larger periodicities are different in respective cycles.

The discussion was separated into 3 different topics according to the separation made by the reviewer between the different periods of waves observed in the sun :1) global modes (long period oscillations) with predominantly radial harmonic motion.2) modes with large coherent - wave systems but not necessarily global excitation (300 s oscillation).3) locally excited - short period waves.

Today, in image analysis the broadest possible rationalization and economization have become desirable. Basically, there are two approaches for image analysis: The image analysis through the so-called scanning methods which are usually performed without the human eye and the systems of optical semiautomatic analysis completely relying on the human eye.The new MOP AM 01 opto-manual system (fig.) represents one of the very promising approaches in this field. The instrument consists of an electronic counting and storing unit, which incorporates a microprocessor and a keyboard for choice of measuring parameters, well designed for easy use.Using the MOP AM 01 there are three possibilities of image analysis:the manual point counting,the opto-manual point counting andthe measurement of absolute areas and/or length (size distribution analysis included).To determine a point density for the calculation of the corresponding volume density the intercepts lying within the structure are scanned with the light pen.

Equilibrium Vapor Pressure

In order to observe room temperature hydrated specimens in an electron microscope, the following conditions should be satisfied: The specimen should be surrounded by water vapor as close as possible to the equilibrium vapor pressure corresponding to the temperature of the specimen.The specimen grid should be inserted, focused and photo graphed in the shortest possible time in order to minimize dehydration.The full area of the specimen grid should be visible in order to minimize the number of changes of specimen required.There should be no pressure gradient across the grid so that specimens can be straddled across holes.Leakage of water vapor to the column should be minimized.
