The paper describes a new method of body equilibrium evaluation applied for different human subjects, the principal aim being to demonstrate to what extent any locomotory diseases could influence the body stability and equilibrium. The research refers to identify some persons with different locomotory diseases and to find both the influence on equilibrium and stability and if possible to improve them. Our research stage, synthesized in this paper, explains the body equilibrium evaluation in orthostatic posture done for different subjects, aged between 20 and 40 years. A number of 10 relevant persons were considered to be evaluated, 2 of them having some locomotory diseases. The first person presents any neuro-motor stability problems in case of long standing case. The other person has both Achilles tendons torn and operated. All subjects were tested in orthostatic posture, in 3 distinct positions, using a Kistler force plate. The experiments referred to the body mass center (COM) displacement in sagittal and lateral planes, representing an interesting characteristic for its equilibrium. It was shown that the person with diseases affecting stability presented a loss of equilibrium when standing for 10-20 seconds, i.e. higher COM displacements in both planes reported to the other tested subjects.

Immersed boundary method has got increasing attention in modeling fluid-solid body interaction using computational fluid dynamics due to its robustness and simplicity. It usually simulates fluid-solid body interaction by adding a body force in the momentum equation. This eliminates the body conforming mesh generation that frequently requires a very labor-intensive and challenging task. But accurately tracking an arbitrary solid body is required to simulate most real world problems. In this paper, a few methods that are used to track a rigid solid body in a fluid domain are briefly reviewed. A new method is presented to track an arbitrary rigid solid body by solving a transformation matrix and identifying it using a level set function. Knowing level set function, the solid volume fraction can be derived if needed. A three-dimensional example is used to study a few methods used to represent and solve the transformation matrix, and demonstrate the presented new method.

The treatment of asphyxia neonatorum was rarely mentioned in American medical literature until the second half of the last century. A few anecdotal papers were published in the early 1800's, including one by Dr. Gilbert Smith, Physician and Surgeon to the New York Almshouse. His "new method" was described as follows1: About three years since I was called upon to attend a lady with her first child; it being a breech presentation, the labor was of course tedious and the head was retained such an unusual length of time after the body was delivered, that, apprehending the most serious consequences, I directed a warm bath to be in readiness, into which the child was placed immediately after delivery. At this time there was no pulsation in the chord [sic], or the smallest sign of life. Its legs and spine were frequently rubbed with stimulating applications, which I was assiduously employed in endeavoring to excite action in the lungs by breathing into them, and pressing out the air alternately. This process was carried out for the unprecedented period of two hours, when my strength failing, I was upon the point of discontinuing any farther effort as useless; when one of the attendants, by whose importunity I was, perhaps, induced to persevere for such a length of time, proposed by taking some brandy and water; after having drank, I resumed my labors, when the idea forcibly struck me that the alcohol might be volatilized by the heat of the mouth and breathed into the lungs.

AbstractMost prescribing indications in homœopathy are derived from clinical experience. There is a need to revise and update them. A new method known as systematic outcome correlation, which correlates outcome as measured by a standard clinical assessment, with prescription, is described. The method uses information technology and the Read clinical classification. Preliminary results in rheumatoid arthritis are presented. The method and results are critically examined with recommendations for future developments.

The various sets of basis functions useful in discussing cubic crystals must include sets of symmetrized combinations of powers of the co-ordinates ortho-gonalized over the cellular polyhedron. Such polynomials are here called solid harmonics. A study of the actual solid harmonics reveals the limitations of the spherical cell approximation. The solid harmonics can be used to develop a new method over the cellular polyhedron of the body-centered cubic lattice or of the face-centered cubic lattice.
