Aim: To evaluate and compare the sorption solubility of three modified glass ionomer cements –Glass Hybrid Restorative System (Equiaforte), Zirconomer Improved resin cement (RMGIC) in artificial saliva. Materials And Methods: A total 45cylindrical specimens (4mm diameter 6mm height) were prepared for each material following manufacturer’s instructions. After subjecting to thermocycling 500 cycl...

Armor steel is a special grade of that commonly designed for providing protection the army resources from different piercing ammunitions. This must be assessed through its mechanical properties, and ballistic resistant to confirm their ability withstand resistance armor-piercing ammunition, before being subjected use. Case study armor sheet 6mm thickness has been normal test EN1522, one project...

Hydroxyapatite is a material that has the same structure and composition as main minerals of human teeth bones. This study's purpose was hydroxyapatite synthesis determining effect variations in ball sizes, ratio mass precursors to balls size, milling time, size crystals particles, surface area morphology produced by mechanochemical method. Two different sizes (3mm 6mm) three powder 1:1.44; 1:2...

Concrete is poor in tensile property due to its brittle nature. Improvement the mechanical properties of concrete carried by combining rebars and fibers concrete. Earlier research state that non-metallic fibres improve pre-crack performance metallic post crack performance. Short resist micro-cracks at an early stage long macro-cracks. The combination short makes much effective. In this study, i...

We examined faunal community responses to oxygen and organic matter gradients across the lower oxygen minimum zone (OMZ) on the bathyal Pakistan margin, where sediments grade from fully laminated sediment at 700m (0.12mLL 1 O2 [5mM]) to highly bioturbated sediment at 1100m (0.23mLL 1 O2 [10mM]). High-resolution sampling of the seafloor (every 50m water depth) was conducted along a single transe...

Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...

Certain species of Hermetia illucens, also known as the Black Soldier Fly(BSF), were found in a compost plant in Roorkee located in Northern India. Its larvae arevoracious eaters of organic waste, hence can play an ecologically-important role in solidwaste management. Morphological analysis of various stages of BSF life cycle by SEMshowed that its body along with its wings is densely covered wi...

We present the case of a 69-year-old man with a rectal granular-type laterally spreading tumor (LST) of about 50mm in diameter who underwent endoscopic submucosal dissection (ESD) using a Hybrid knife I-type (Erbe, Tübingen, Germany) at our institute (●" Fig.1). The following day, the patient developed rectal bleeding, and endoscopy revealed a large post-ESD ulcer with clots at the base (●" Fig...

Automatic co-alignment of optical and virtual colonoscopy images can supplement traditional endoscopic procedures, by providing more complete information of clinical value to the gastroenterologist. In this work, we present a comparative analysis of our optical flow based technique for colonoscopy tracking, in relation to current state of the art methods, in terms of tracking accuracy, system s...
