While the capacity of Mobile Ad Hoc Networks (MANETs) has received considerable attention, the issue of endto-end latency has been largely ignored. As MANETs get larger and denser with an increasing number of end-to-end hops, the latency and jitter experienced by packets will be prohibitively high for existing and emerging real-time applications. We present and evaluate a design concept for ach...

Self-healing in orthopedic bone cement is demonstrated with a novel thermoplastic solvent-bonding approach. Low toxicity solvent-filled microcapsules, embedded in a commercial acrylic bone cement matrix, enable recovery of up to 80% of the virgin fracture toughness of the cement at room and body temperature conditions without external stimuli or human intervention.

Cement is one of the mostly used construction materials due to its high durability and low cost, but it suffers from brittle fracture and facile crack initiation. This article describes the use of naturally-derived renewable cellulose nanofibers (CNFs) to reinforce cement. The effects of CNFs on the mechanical properties, degree of hydration (DOH), and microstructure of cement pastes have been ...

Bone cement containing gentamicin may release antibiotic when fractured during revision operations. Tissue samples taken during surgery may be contaminated by gentamicin and give inaccurate microbiological assessment. We studied five patients in whom cement containing gentamicin had been used in the primary procedure. During revision hip replacement, samples of joint fluid, tissues and cement w...

The main aim of this study was to conduct an integrative review on the influence zirconia veneer thickness degree conversion resin-matrix cements. An electronic search performed PubMed using a combination following items: zirconia, thickness, veneer, conversion, resin cement, light curing, and polymerization. Articles published in English language, up July 2020, were included regarding ceramic ...

Solidia CementTM is a non-hydraulic cement composed primarily of low-lime containing calcium silicate phases such as wollastonite / pseudowollastonite (CaO·SiO2), and rankinite (3CaO·2SiO2). This contrasts the high-lime alite (3CaO·SiO2), belite (2CaO·SiO2), tricalcium aluminate (3CaO·Al2O3), tetracalcium aluminum ferrite (4CaO·Al2O3·Fe2O3), and gypsum (CaSO4·2H2O) phases that comprise ordinary...

Introduction: In the Kindling-induced seizure model, low and repeated electrical or chemical stimulations, can elevate the neural network excitability and induce epileptiform seizures. Opioid receptors are widely distributed in different areas of the brain. On the other hand, morphine has paradoxical effects and induces elevation or alleviation of the pain sensation and excitability, at diff...

All biological samples emit ultra-low intensity light without any external stimulation. Recently, scientific communities have paid particular attention to this phenomenon, known as ultra-weak photon emission (UPE). UPE has been introduced in the literature as an alternative for biophoton, low-level chemiluminescence and ultra-weak bioluminescence, while it differs from ordinary bioluminescence,...
