LIGHTWEIGHT CONCRETE May consist of lightweight aggregates are used in ordinary concrete of coarse aggregate and sand, clay, foamed slag, clinker, crushed stone, aggregates of organic and inorganic. It used in different common shapes such as light weight aggregate concrete [1], concrete without fine [2] or concrete with bubble [3]. It is replaced by normal concrete in several applications becau...

We analyze a well known type of puzzle in planar geometry: given a planar shape, it is required to find a cut that divides the shape into two identical parts (up to rotation and translation). Clearly not all shapes can be so dissected and for some shapes that appear in puzzles the cutting curve is quite surprising and difficult to find. In this paper we first analyze the inverse problem of asse...

To increase the resistance to fungal corrosion and improve performance of concrete cement stone, it is proposed introduce calcium stearate active metal nitrates in an amount 0.5% by weight into mixture at manufacturing stage. determine degree damage stone microorganisms Aspergillus niger, porosity, density, water absorption strength were determined. It has been found that introduction a hydroph...

As a result of intrastratal and interlayer flows produced water varying intensity, 25% oil gas wells are water-encroached in the world. Due to behind casing flow during operation generally reduces field's development efficiency. In study, 1-6% (weight) polyethylene polyamine (PEPA) was added which cement mixture will be prepared. The temperature dependence beginning end setting time obtained mo...

Heartbeat shape-discriminator (PSD) has been used all through the past 40 years in radiation area structures reaching out from remedial demonstrative imaging cams to high imperativeness material science. The limit of PSD is to partitioned radiation signs in perspective of particular sign shape. It can be used to perceive the sparkle sort in (Depth of affiliation) DOI PET application, where the ...

tion of the minor papilla in pancreas divisum A 70-year-old woman was admitted with an episode of epigastric pain radiating into her back, accompanied by intermittent nausea and vomiting. Acute pancreatitis was diagnosed and transabdominal ultrasound revealed a dilated pancreatic duct of 6mm due a ductal stone. The first attempt of endoscopic retrograde pancreatography (ERP) failed to cannulate...

Coherent Deformable Model Yusuf Sinan Akgul Chandra Kambhamettu Maureen Stone Department of Computer and Information Sciences Division of Otolaryngology University of Delaware The University of Maryland Medical School Newark, Delaware 19716 Baltimore, Maryland 21201 Abstract We present a system that extracts and tracks 2D midsagital tongue surfaces from ultrasound image sequences produced by a ...

The motion of a stone skimming over a water surface is considered. A simplified description of the collisional process of the stone with water is proposed. The maximum number of bounces is estimated by considering both the slowing down of the stone and its angular stability. The conditions for a successful throw are discussed. © 2003 American Association of Physics Teachers. @DOI: 10.1119/1.151...
