Critical Exponents of Gelation and Conductivity in Polyacrylamide Gels Doped by Multiwalled Carbon Nanotubes
(Taylor & Francis Ltd, 2010)
Polyacrylamide (PAM) doped by multiwalled carbon nanotube (MWNT) gels were prepared with different amounts of MWNTs varying in the range between 0.1 and 15 wt%. The PAM-MWNT composite gels were characterized by the steady ...
Space-Time Block Coding for Spatial Modulation
(IEEE, 2010)
Space-time block coded spatial modulation (STBC-SM) which employs space-time block coding (STBC) for spatial modulation (SM) is proposed as a new multiple-input multiple-output (MIMO) transmission scheme. In the STBC-SM ...
Joint Channel Estimation and Equalization for OFDM based Broadband Communications in Rapidly Varying Mobile Channels
(IEEE, 2010)
This paper is concerned with the challenging and timely problem of channel estimation for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very rapidly time varying ...
Fractal Features and Structural Morphological Optical Characteristics of Sol-Gel Derived Silica Nanoparticled Thin Films
(Polish Acad Sciences Inst Physics, 2018)
Nanostructured silica films using a simple and effective sol-gel spin coating technique were synthesized and the influence of ammonia/sol ratios on the particle size and thickness of this film was investigated. In addition ...
Thiols malonaldehyde status in the Turkish and total antioxidant patients with type 2 diabetes mellitus
(Tohoku Univ Medical Press, 2003)
Non-insulin-dependent (Type 2) diabetes mellitus (NIDDM) is a risk factor for cardiovascular diseases (CVD). Oxidative stress mechanisms are often reported to be implied in type 2 diabetes mellitus. In order to determine ...
Hyperuricemia in hypothyroidism: Is it associated with post-insulin infusion glycemic response?
(Tohoku Univ Medical Press, 2003)
This experimental study was designed to examine whether hyperuricemia in hypothyroidism is associated with insulin resistance. For induction of hypothyroidism rabbits (n = 12) were administered methimazole orally (75 mg/100 ...
Hemodilution during off-pump coronary artery bypass grafting: Can we improve flow and reduce hypercoagulability?
(Forum Multimedia Publishing LLC., 2003)
Background: The aim of this study was to compare intraoperative coronary graft flows performed on pump and off pump and to evaluate the effects of hemodilution on coronary graft flows in off-pump coronary artery bypass ...
Surgical management of the spinal deformity in Ehlers-Danlos syndrome type VI
(Springer Verlag, 2003)
Five patients with Ehlers-Danlos syndrome type VI were surgically treated for their spinal deformities. All of them were female. All but one had a double-major thoracic and lumbar curve. One had a mild scoliotic curve but ...
Vertebral osteomyelitis after cardiac surgery
(Elsevier Science Inc, 2003)
Background. Mediastinitis after open-heart surgery is a serious complication that has a decreasing incidence but still a significantly high mortality rate. Back pain may develop during the course of treatment for mediastinitis ...
Juxtapapillary diverticulum: Findings on MRI
(John Wiley & Sons Inc, 2003)
The purpose of our study was to describe the imaging findings of juxtapapillary diverticulum on magnetic resonance imaging (MRI). The MRI and magnetic resonance cholangiopancreatography (MRCP) examinations of 14 patients ...
