Dense volumes of duplex stainless steel are manufactured by directed energy deposition. Compact tension specimens machined from these in order to evaluate the fracture toughness two directions : parallel or perpendicular deposited layers. Different values measured cases. In understand this anisotropy, additional analyzes performed on cracked post-mortem. A classical metallography analysis revea...

abstract   background: recently, small dense low density lipoprotein (sdldl) has been highlighted as a new risk factor for the coronary artery disease (cad).small dense ldls are believed to be atherogenic since these particles are taken up more easily by arterial wall. they are readily oxidized and have reduced affinity for low density lipoprotein (ldl) receptor and increased affinity for arter...

PURPOSE/OBJECTIVES To determine whether women receiving dose-dense chemotherapy for breast cancer experience different levels of fatigue than women receiving standard chemotherapy regimens for the disease. DESIGN Quasi-experimental pilot study. SETTING Private physicians' offices in California. SAMPLE 15 women with stage I, II, or III breast cancer receiving dose-dense or standard chemoth...

In many complex networks there is a relatively small group of participants that is well connected and highly influential. In order to understand the whole network and the underlying mechanisms it is very helpful to study the characteristics and the emergence of such a group. Many functional properties are associated with high degree nodes and their interconnectivity patterns (rich-club phenomen...

Platelet dense granules (PDGs) are acidic calcium stores essential for normal hemostasis. They develop from late endosomal compartments upon receiving PDG-specific proteins through vesicular trafficking, but their maturation process is not well understood. Here we show that two-pore channel 2 (TPC2) is a component of the PDG membrane that regulates PDG luminal pH and the pool of releasable Ca(2...

background: nasal fracture is a common fracture due to trauma. gold standard method in diagnosis of nasal fracture is clinical examination and radiography is used in legal situation. recently, ultrasound is recommended as a noninvasive and simple method in diagnosis of nasal fracture. this study investigates the role of ultrasound in diagnosis of nasal fracture. methods: 126 cases with suspecte...

This study investigated how the compositional properties and formulation design of commercial cream cheese products model influenced physical structural as compared to a composition. Of seven evaluated, three were block format (B), two spreadable (S) light (SL), with fat contents ranging from 13.7 35.7%. The majority indicated inclusion starter culture, all formulations contained one or more st...

The cement sheath is an annular structure between casing and formation, which crucial to the integrity of wellbore system. Considering that temperature pressure environment changing continuously with increasing burial depth, micro-structure macro=mechanical properties in-situ will change accordingly. To investigate variation depth on evolution tensile mechanical behavior oil stone, five tempera...

background:  hip fracture management in supine position on a fracture table with biplane fluoroscopic views has some difficulties which leads to prolongation of surgery and increasing x- rays’ dosage. the purpose of this study was to report the results and complications of hip fracture management in lateral position on a conventional operating table with just anteroposterior fluoroscopic view. ...
