Dynamic behavior of soil are evaluated relative to a number of factors including: strain level, density, number of cycles, material type, fine content, geosynthetic inclusion, saturation, and effective stress .This paper investigate the dynamic behavior of saturated reinforced sand under cyclic stress condition. The cyclic triaxial tests are conducted on remolded specimens under various CSR whi...

The torsion property and rotary fatigue fracture behavior of Smart K file and R reamer made of nickel titanium alloy have been studied by means of Shimadzu Autograph DDS-10T universal tester and man-made cyclic system with curved copper tubes as simulated root canal. The instrument surface and the cyclic fatigue fracture surface have been investigated by optical microscope and scanning electro...

We describe a patient with methicillin-resistant Staphylococcus aureus (MRSA) who developed resistance to daptomycin, a new cyclic lipopeptide recently approved for the treatment of infections by gram-positive organisms. Development of resistance to daptomycin during prolonged use may occur with MRSA bacteremia

Daptomycin, a new cyclic lipopeptide, was recently approved for the treatment of infections by gram-positive organisms, including infections with methicillin-resistant Staphylococcus aureus (MRSA). A patient infected with infected with MRSA developed resistance to daptomycin after prolonged exposure, which resulted in clinical failure. Clinicians should be aware of the possibility of daptomycin...

The recognition in the early 1960s by Morifusa Eto that tri-o-cresyl phosphate (TOCP) is hydroxylated by the cytochrome P450 system to an intermediate that spontaneously cyclizes to a neurotoxic phosphate (saligenin phosphate ester) ignited the interest in this group of compounds. Only the ortho isomer can cyclize and clinically cause Organo Phosphate Induced Delayed Neurotoxicity (OPIDN); the ...

Degradation of the cementitious bond between steel rebar and concrete and that between old and new mortar under cyclic shear loading was observed nondestructively by measuring the contact electrical resistance of the joint. Degradation, which caused a decrease in bond strength but no visual damage, was indicated by an abrupt increase in the resistance at a small fraction of the fatigue life. Bo...

The item deals with the possibilities of utilization HVOF coatings in thermal cyclic loading conditions. There were evaluated three types of coatings based on WC-Co, WC-Co-Cr and Cr3C2-25NiCr. The quality of coatings was evaluated in terms of their adhesion as sprayed and also during the cyclic thermal loading, EDX analysis and evaluation of microhardness. Construction and structure of coatings...

Abstract Bronze has been used for various applications since ancient times, and therefore, its preservation is critical. However, preserving bronze challenging. The traditional inhibitor sealing method limited by toxicity effects. In this study, a benzotriazole (BTA) loaded with composite hydrogel of sodium alginate cyclic-peptide-grafted β-cyclodextrin was prepared. chemical structure the comp...

UNLABELLED Mutations in the Plasmodium falciparum cyclic amine resistance locus (PfCARL) are associated with parasite resistance to the imidazolopiperazines, a potent class of novel antimalarial compounds that display both prophylactic and transmission-blocking activity, in addition to activity against blood-stage parasites. Here, we show that pfcarl encodes a protein, with a predicted molecula...
