Summary form only received as follows: The objective of this study was to evaluate the use of a polybutene additive to improve the flexure strength of cold cured acrylic systems. Three different number average molecular weight polybutenes were used including H100 (920 g/mole), L65 (610 g/mole) and L14 (320 g/mole) (Amoco Chemical Co.). The polybutenes were blended at 0, 1, 5 and 10 weight % with a cold cure acrylic system and compression molded into rectangular specimens 13 mm wide x 3 mm thick x 28 mm long. Ten specimens were prepared for each formulation and stored for seven days in distilled water at 37/spl deg/C before flexure testing. A three point flexure test was run using a span of 20 mm at a rate of 1 mm/minute. The results for the cold cure acrylic are given. The only polybutene formulation which improved the flexure strength was the 1% H100 composition. Although the 1% H100 formulations did improve the flexure strength of the acrylic, the change was not statistically significant when compared using a t-test (p <.05). Incorporation of polybutenes did not significantly improve the flexure strength of dental acrylics tested in this study.

Our previous studies have used jet impingement techniques to quantify strength of cell adhesion to various material surfaces. Surface charge and energy parameters were found to mediate the strength of cellular adhesion. The present investigation examines biological factors which might influence fibroblast adhesion to biomaterials-biofilm composition and cell morphology. Also, the relationship of surface charge to cellular adhesion has been investigated in a controlled way by measuring adhesion strength over a range of surface charge densities. The cells showed potential dependent adhesion maxima which suggests that surface alloying for optimum adherence may be possible. The adsorbed serum protein biofilms on a series of materials of differing adherence were investigated using gel electrophoresis. The profiles of adsorbed proteins revealed little difference in relative abundance or total adsorption quantity. SEM micrographs of the cells on a titanium alloy and silicone rubber (high and low adhesion materials, respectively) showed morphologic and cell density differences.

Stress shielding in metallic implants used in total hip arthroplasty is often mentioned as the cause of loosening in many clinical cases. In this study the stress shielding was evaluated in Ti6Al4V alloy commercial femoral components with and without collar. The results from the strain gauge measurements showed that the stress shielding was lower for femoral components collar than that seen without collar.

In an electroporation system, a biomechanical function is proposed, based on Newton's Second Law, for a small patch with proteins and lipids, in a cell membrane and on the positive or the negative side. Two biomechanical models of the critical potential deference /spl Delta//spl psi//sub 0/ of electroporation are developed from the function. One is expressed in terms of the Law of the Conservation of Energy and another one is presented in terms of the Impulse-Momentum principle. The two models elucidate that: /spl Delta//spl psi//sub 0/ is proportional to the mass m, the thickness L and the departure velocity v/sub L/ of the patch and the electric attraction force f between the patch and the cell membrane; /spl Delta//spl psi//sub 0/ is inversely proportional to the net charge q carried by the patch and the absolute temperature T of the system. A concept of work function /spl phi//sub w/ of electroporation is proposed and /spl phi//sub w/ is described as /spl phi//sub w/=q /spl Delta//spl psi//sub 0//2 in the first model. The second model particularly indicates that /spl Delta//spl psi//sub 0/ and the critical width /spl tau//sub 0/ of the externally imposed electric pulse can compensate each other. Many previous experimental results can be qualitatively explained with the two models. The essential and sufficient conditions of electroporation occurrence at the patch are proposed too. The essential condition is -qd/spl psi//dx>f and the sufficient condition is /spl tau/>/spl tau//sub 0/, where -d/spl psi//dx and /spl tau/ are the electric field at the patch and the pulse width respectively.

Ever since independence, concern for health has been of major and priority importance in Indian planning. National health policy has affirmed the aim of effective health care for all by the year 2000. Keeping this in view, the government of India has enacted a number of legislations on safety and occupational health in industry. Here, the authors focus on the development and present status and problems of occupational health and the design of appropriate strategies for better occupational health care and safety. To face the challenge of a liberalized market, more sophisticated technology and competition, industries need not only people with skill, ability, and knowledge, but also sound health and mind. Different health and safety measures have been strengthened following a big disaster in Bhopal in 1984. A number of large scale technology intensive industries have adapted a number of health and safety measures for their employees. But this receives very little attention in small and medium sector units where a large proportion of people are employed. There are also other problems both at the national and industry levels for making a sound safety and occupational health program successful in a developing country like India. While probing into these problems a few strategies have been formulated for a sound safety and occupational health service.

Using computer aided design tools, new total joint prostheses and surgical procedures have been designed to restore normal mechanics and thereby offer hope for improved patient outcome, To obtain improved outcome at a reduced cost, new total joint implant systems must allow the surgeon to restore joint mechanics without overloading prosthetic or skeletal materials. Current techniques often fail to restore normal joint function, Many replacement arthroplasties have experienced an unacceptable rate of loosening. Normal joint mechanics depend on recreation of the joint's kinematic mechanism, In our work average kinematic parameters are used to define mathematical models of the joint surfaces. Duplication of the normal joint is accomplished, However, a series of kinematically correct surfaces can be designed for any given joint. Surface and interface geometries can be varied to take into account the strengths and weaknesses of the prosthetic and biologic materials. New hand prosthetic design alternatives are discussed in detail. The importance of surface asymmetry in stabilizing normal and prosthetic joints, and the processes used to create and analyze specific joint models are also highlighted.

The estimation of the pre operation and post operation canal geometry and interpedicular distance of burst fracture clinical cases has not been well documented. In this study a quantitative method was developed to estimate these parameters from clinical CT images in a SUN 2GX SPARCstation using the SUN VISION Software. In an initial cadaveric study the methods to estimate these parameters were set and it was found that the bone mineral density (BMD) correlated with the fracture load, degree of canal encroachment and changes in the interpedicular distance (IPD). For the nine burst fracture patients, the BMD correlated with the degree of canal encroachment but not IPD changes. After several months, the hardware was removed in three patients. The canal area increased and the IPD decreased in the affected vertebral body, showing significant recovery in each case.

Traditionally, speech recognition systems use only the acoustic speech signal (speech). However, the source of the signal and the way speech is produced and whether this information can aid in speech recognition needs to be investigated. The objective of this study was to assess the contribution of using the electroglottograph (EGG) as an additional source of information along with speech in an isolated word recognition system. The vocabulary consisted of 64 words, ranging from mono-syllabic words to words with four syllables. Two fully connected artificial neural networks were designed. One network (speech network) used only speech as its source of information. The other network (speech+EGG network) used EGG along with the acoustic speech signal as its source of information. The speech network had a peak recognition rate of 94.37%. The speech+EGG network had a peak recognition rate of 99.37%. Hence, the information provided by the EGG improved the performance of the speech recognition system by 5%.
