New natural observer applied to speed-sensorless DC servo and induction motors
(Ieee-Inst Electrical Electronics Engineers Inc, 2004)
A simple observer design technique with parameter adaptation is proposed for bounded-input bounded-output nonlinear systems. In this technique, no feedback is used in the observer but parameter estimations are considered ...
The scanning electron and light microscopic structure of bovine tactile hair
(Blackwell Verlag Gmbh, 2004)
Bovine tactile hairs in skin samples from the lateral side of the upper lip were examined using scanning electron and light microscopy. The root of these hairs has a variable length and is surrounded by a large sinus located ...
Estimation of solar potential in Turkey by artificial neural networks using meteorological and geographical data
(Pergamon-Elsevier Science Ltd, 2004)
Turkey is located at the Mediterranean at 36degrees and 42degrees N latitudes and has a typical Mediterranean climate. The solar energy potential is very high in Turkey. The yearly average solar radiation is 3.6 kW h/m(2) ...
Characterisation of tyrosinase immobilised onto spacer-arm attached glycidyl methacrylate-based reactive microbeads
(Elsevier Sci Ltd, 2004)
Immobilisation of tyrosinase onto modified poly(methyl methacrylate-glycidyl methacrylate-divinyl benzene), poly(MMA-GMA-DVB), microbeads was studied. The epoxy group containing poly(MMA-MMA-DVB) microbeads were prepared ...
Investigation of thermodynamic properties of refrigerant/absorbent couples using artificial neural networks
(Elsevier Science Sa, 2004)
This paper presents a new approach to determine the properties of liquid and two phase boiling and condensing of two alternative refrigerant/absorbent couples (methanol-LiBr and methanol-LiCl), which do not cause ozone ...

Prevalence of Helicobacter pylori in patients with nasal polyps: A preliminary report
(Wiley, 2004)
Objectives: The aim of the study is to determine the presence of H. pylori in nasal polyps by both immunohistochemical staining with H. pylori antibody of biopsy specimens and enzyme-linked immunoadsorbent assay (ELISA) ...
Fungal growth inside saline-filled implants and the role of injection ports in fungal translocation: In vitro study
(Lippincott Williams & Wilkins, 2004)
Infection is a serious complication of breast. augmentation and tissue expansion with inflatable devices. Several reports have shown that fungi may be able to survive, colonize, and even cause infection in saline-filled ...
The effect of Helicobacter pylori eradication on gastroesophageal reflux disease
(Lippincott Williams & Wilkins, 2004)
Background: The effect of Helicobacter pylori (H. pylori) eradication on gastroesophageal reflux disease is controversial. We aimed to investigate the effect of H. pylori eradication in this group of patients. Materials ...
