Compressive Strength Of Concrete

There have been many experimental measurements of the waterproofing ability of concrete with a crystalline admixture. For the comprehensive evaluation of crystalline admixtures, it is necessary to consider their effect on the compressive strength of concrete fck, not only their waterproofing ability. The paper describes laboratory testing which subject was the selected crystalline admixtures effect on the compressive strength of concrete fck. The results have shown that the compressive strength fck,cubeof concrete with a crystalline admixture (added in an amount of 2%) was almost identical to the specimens from concrete without admixture after 28 days. The compressive strength of the next specimens from cement mortar with a smaller amount of a crystalline admixture (1%) after the 28 days was higher than the strength of the specimens without admixtures.

In this work, a testing protocol has been set up, in order to quantify the load-sharing imposed near the fracture site by an interlocking-type intramedullary nail. A simulated single-leg stance has been applied to a composite fiberglass femur in three different configurations simulating: an intact femur, a fractured nailed femur and a fully healed nailed femur. The repeatability of the measurements and the influence of ilio-tibial band muscle force have been investigated. The tested nail proved to share with the femoral shaft an amount of the total applied load ranging from 50% immediately after the nailing to 80% at full healing.

Background Durable and locally fabricated prosthetic feet are important for developing countries. Modifications to the current CR solid ankle–cushion heel prosthetic foot could enhance current foot characteristics and reduce costs. The goal of this project was to modify the keel and rubber outer foot shell to enhance features and reduce costs of the current CR solid ankle–cushion heel offering. Methods The prosthetic foot was designed, fabricated and then tested mechanically for strain and displacement in a cyclic testing machine according to a component of the ISO-10328 testing protocol. Dynamic cyclic testing of both forefoot and heel portions of the foot was conducted. Findings Dynamic mechanical cyclic testing of the forefoot and heel at 1.28 kN for two million cycles at a rate of 1 Hz was successfully achieved. The final cost of producing the foot was roughly $16 USD. Limitations include the inability to perform the full battery of ISO-10328 foot testing, UV testing and a limitation to laboratory testing. Clinical studies examining practical application of the modified foot should be conducted.

Abstract To properly assess men and women with sexual dysfunction, evaluators should take a biopsychosocial approach that may require consultation with multiple health care professionals from various fields in order to get to the root of the sexual dysfunction; this multidisciplinary methodology offers the best chance of successful treatment. For males, this article focuses on erectile dysfunction (ED) and hypogonadism. The initial evaluation of ED involves a thorough case history, preferably taken from the patient and partner, physical examination, and proper laboratory and diagnostic tests, including an acknowledgment of the subjective complaint. The diagnosis is established on the basis of an individual's report of the consistent inability to attain and maintain an erection sufficient to permit satisfactory sexual intercourse. Initial workups for ED should entail a detailed history that can be obtained from a validated questionnaire such as the International Index of Erectile Function and the Sexual Health Inventory for Men. Hypogonadism is evaluated using the validated Androgen Deficiency in the Aging Male questionnaire and laboratory testing for testosterone deficiency. Treatments logically can begin with the least invasive and then progress to more invasive strategies after appropriate counseling. The last and most important treatment component when caring for men with sexual dysfunction—and, arguably, the least practiced—is close follow-up.
