Concrete's ability to auto-repair the cracks reduces need for maintenance and repair. Autogenous self-healing is an intrinsic property of concrete highly dependent on binder composition. The urgent necessity decrease CO2 emissions by replacing cement with “greener” materials provides challenges opportunities cementitious materials. This research aims verify behavior environmentally friendly mul...

Introduction The bony insertion of the anterior cruciate ligament (ACL) is comprised of four distinct zones: ligamentous tissue, noncalcified fibrocartilage, calcified fibrocartilage, and bone. This “enthesis” is responsible for effectively transmitting the forces from the elastic ligament to the stiff bone. Despite its well organized structure, the enthesis has limited vascularity and thereby ...

OBJECTIVE To volumetrically evaluate soft tissue changes of different ridge preservation techniques compared to spontaneous healing 6 months after tooth extraction. MATERIALS AND METHODS In each of 40 patients, one single-rooted tooth was extracted and four treatment modalities were randomly assigned to the following groups (n = 10 each): A) ß-tricalcium-phosphate-particles with a polylactid ...

Abstract Several factors, such as chemical shrinkage or environmental attack can produce concrete cracks. Calcium hydroxide content from the environment cement hydration promote self-healing phenomenon (SHP). This study evaluates calcium concentration influence on of cement-based materials. Cracked mortars with different types cement, a filler, pozzolanic, and high initial strength, were expose...

INTRODUCTION Bone regeneration grafts (BRG) are widely used in the treatment of osseous defects and oral surgery. The various techniques and associated success rates of bone augmentation require evaluation by systematic review and meta-analysis of eligible studies. The aim of this systematic review was to compare alveolar bone regeneration in humans using Bio-Oss and autogenous bone graft. MA...

The decreased incidence of potentially autogenous Gramnegative bacillary infections may well be unrelated to the change in ward architecture, but the criteria used to classify cross-infection meant that some of the intestinal type of infections labelled autogenous were in fact cross-infections. As expected, the incidence of definite staphylococcal autogenous infection remained substantially the...

More than one century after its massive introduction in the building industry, concrete is still most popular material. Nevertheless, several critical infrastructures show severe signs of distress. This fact fostered, recent years, need rethinking design process structures, view reducing maintenance costs and extending their service life. work has been performed framework H2020 project ReSHEALi...
