Optimized spectrum sensing using distributed detection techniques for secondary user spectrum access is becoming important in Cognitive Radio (CR) systems, which have been proposed to utilize the available frequency spectrum more efficiently. For achieving best performance and ensuring minimal acceptable interference to spectrum owners, it is important to accurately sense and detect the presenc...

The functionality of caseins in food systems depends on their solubility. The solubilities of whole casein, cr,l-casein, /3-casein, and dephosphorylated whole casein were measured as the pH was adjusted from 7 to 2 with HCl. When NaCl was added before pH adjustment, solubilities of whole casein at pH 2.5 decreased by 25, 40, 85, and 98% at NaCl concentrations of .01, .05, .1 and .2 M, respectiv...

INTRODUCTION This cross-sectional survey determined the dental prevalence of apical periodontitis (AP) in selected Iranian population, and evaluated the influence of the quality of root canal treatment (RCT) and their coronal restorations (CR) on the periapical status. MATERIALS AND METHODS A total of 1064 panoramic radiographies were evaluated by two observers during 2009. The quality of RCT...

PURPOSE To evaluate the efficacy and toxicity of Hyper-CVAD (fractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone), a dose-intensive regimen, in adult acute lymphocytic leukemia (ALL). PATIENTS AND METHODS Adults with newly diagnosed ALL referred since 1992 were entered onto the study; treatment was initiated in 204 patients between 1992 and January 1998. No exclusions w...

Soil properties may change due to climate change, but in recent times, the changes occur as a result of anthropogenic activities such metal workshop operations. This study was conducted assess impact contamination on human health operating workshops. In this research work which carried out estimated risk heavy around workshops, five different Garejin Oga Abdul (GOA), Nakowa Welding Construction...

INTRODUCTION The accurate diagnosis and monitoring of idiopathic Parkinson disease (PD), a progressive neurodegenerative disorder, has not been fully developed. This study sought to identify a neurochemical profile in multiple regions of the PD brain and healthy controls by proton magnetic resonance spectroscopy (1H-MRS). We aimed to track changes of the brain neurochemical, quantify neuronal l...

Caloric restriction (CR), which increases longevity and retards age-associated diseases in laboratory rodents, is being evaluated in nonhuman primate trials. CR reduces oxidative stress in rodents and appears to improve risk factors for cardiovascular disease in nonhuman primates. We tested the hypothesis that low-density lipoprotein (LDL) oxidizability is reduced in two monkey species (rhesus ...

This study focused on the identification of suitable lipase or esterase activity for enantiomeric resolution of (R,S)-naproxen. For an economically viable reaction the enantiomeric ratio (E) should preferably be >100, while maximising the conversion will reduce the mass of material that requires racemisation and recycling. Hence the aim was to find an enzyme that yields (S)-naproxen with an ena...
