accelerometers as well as other areas. It is due to the piezoresistive gauge factor of diamond to be between 70-4000 and remains as such even at high temperatures. Another advantage of using diamond in these situations is that because its elastic modulus is much greater than other materials that would be used such as Silicon or silicon based compounds the diamond films can operate at much higher frequencies. Although it has been believed that only polycrystalline materials have these piezoresistive
On average, women in the U.S. typically want to have two children (“Unintended Pregnancy in the United States”). In order to accomplish this, a woman will have to spend around three years pregnant, postpartum or attempting to become pregnant. They will also have to spend about three decades trying to avoid an unintended pregnancy, which is more than three-quarters of her reproductive life (“Unintended Pregnancy in the United States”). There are many different reasons that contribute to why most
challenges of corneal ectasia. We evaluated the benefits of ECM via biomechanical, thermal, ultrastructural and gene expression characterization, by treating enzyme digested corneas with ECM conditioned media. ECM treatment demonstrated an increase in Young’s modulus on the KC corneas. Moreover, it restored thermal stability, and regulated gene expression of corneal stromal cells. We have therefore conclusively established that tissue-derived ECM

The present (in vivo) study was carried out in the Department of Orthodontics and Dentofacial Orthopaedics, Faculty of Dental Sciences, King George’s Medical University, Lucknow (U.P.), India; in association with C.I.P.E.T (Central Institute of Plastics and Engineering Technology), Lucknow (U.P.), India to evaluate and compare the effect of intraoral environment on the properties of different alignment wires retrieved from the patients mouth(72 arches) after initial alignment (4 months) .

using numerical integration of one- parameter shooting method. Bishop and drucker [2] investigate large deflection of cantilever beam of linear elastic material. We are using nitinol (nickel titanium alloy) beam it’s having a low modulus of elasticity (E) which shows good spring back behavior which regain its original shape after removing external load. Who’s bending stiffness is low compared to other material like stainless steel. Due to this property at very low external load large
Ultra high temperature ceramics (UHTCs) are materials rarely found in nature, characterized by high melting points, hardness, thermal conductivities (if compared to other ceramics), good wear resistance and mechanical strength.1,2,3 Besides, they are chemically and thermally stable under a variety of conditions due to their high negative free energy of formation.1,3 The materials that fit in these criteria are ceramics compounds made of borides, nitrides and carbides. As a result of having those
Total hip replacement or THR is a clinically effective procedure for the treatment of pain and disability that arises due to the final stage arthritis of the hip. THR is prescribed for the patients who do not respond to the options that are non surgical, self management, education of the patient, physical therapy, acupuncture, and exercise. ( Pivec. et.al,2012). Numerous procedures , a range of implant designs are available and it is the surgeon who has to decide upon as to which type of fixation
3 ,5, 10, 14) wt.% of kaolin powder to obtain desirable properties. The parameters such as tensile strength, tensile modulus, elongation at break , yield stress, impact strength, shore D hardness and water absorption test were carried out on the prepared samples. The results showed that the addition of kaolin powder to the polymer leads to increase the tensile strength, modulus of elasticity, shore-D hardness and impact strength and it decreases the % elongation at break,. Water absorption of the
