TL;DR: In this paper, the authors present experimental study on improving mechanical properties of Al and Al-xSiC nanocomposites synthesized by cumulative roll bonding (ARB) technique.
Abstract: This paper present experimental study on improving mechanical properties of Al and Al-xSiC nanocomposites (x = 1, 2 and 4%) synthesized by Accumulative Roll Bonding (ARB) technique. SEM, EDX and XRD analysis was used to characterize the structural changes in the manufactured materials while tensile and microhardness tests were used to characterize their mechanical properties. Homogeneous distribution of SiC nanoparticles was achieved after five ARB cycles. A significant strength improvement was achieved for processed Al and Al-SiC nanocomposites after five ARB cycles due to grain refinement, grain misorientation and SiC strengthening. The grain refinement and grain misorientation contributed the strength improvement by 161% and 46%, respectively, while the addition of 1% SiC nanopartciles contributed by 78% which is increased to 101% for 4% SiC. The ductility is reduced after the zero ARB cycle however it increased with increasing the number of ARB cycles reaching 8.2 and 5.8% for Al and Al-4% SiC nanocomposites, respectively, after 5 ARB cycles. The fracture shape in the ARBed samples is a combination of necking and shearing with a tendency to shearing shape for Al-SiC nanocomposites.

TL;DR: The overall revision ACL surgery rate after primary unilateral ACL reconstruction was 8.4%, and multivariable logistic regression analysis indicated that age and reconstruction performed with allograft were the only independent predictors of revision ACL reconstruction.
Abstract: Background:Revision anterior cruciate ligament (ACL) reconstruction surgery occurs in 5% to 15% of individuals undergoing ACL reconstruction. Identifying predictors for revision ACL surgery is of e...

TL;DR: A strong correlation was found between hairy tongue and smoking and an association of the two conditions was observed in 2.9% of the subjects.
Abstract: – Over a period of 10 months, 1013 consecutive dental outpatients attending the Screening Clinic in Faculty of Dentistry, Jordan University of Science and Technology, in the city of Irbid were investigated for the presence of tongue lesions. All subjects were seeking treatment for caries and periodontal diseases and none was complaining of oral mucosal disorder. The results showed that 240 subjects (23.7%) had one or more tongue lesions. Geographic tongue and fissured tongue were detected in 6.8% and 11.4% of the examined population respectively, and an association of the two conditions was observed in 2.9% of the subjects. Hairy tongue was diagnosed in 3.4% of the subjects with significantly higher prevalence in males (P < 0.0005). A strong correlation was found between hairy tongue and smoking.

TL;DR: In this paper, a perturbation technique is used to simplify the generalized governing equations of the parabolic two-step model, where diffusion terms in both electron and lattice energy equations are simplified.
Abstract: A perturbation technique is used to simplify the generalized governing equations of the parabolic two-step model The generalized form of the two-step model contains diffusion terms in both electron and lattice energy equations and assumes that incident laser radiation is absorbed by both electron gas and solid lattice to account for the thermal behavior of semiconducting and impure materials The simplified perturbation technique is used to eliminate the coupling between the electron and the lattice energy equations when the temperature difference between the electron and the lattice is a small perturbed quantity, which is true in materials exhibiting high coupling factors A mathematical criterion is derived to determine the conditions under which electron and lattice are in thermal equilibrium It is found that five dimensionless parameters control the state of thermal equilibrium between the lattice and the electron
