In this paper, a frequency-variation based method has been proposed for transistor parameter estimation in a commonemitter transistor amplifier circuit. We design an algorithm to estimate the transistor parameters, based on noisy measurements of the output voltage when the input voltage is a sine wave of variable frequency and constant amplitude. The common emitter amplifier circuit has been mo...

In Drosophila, two related G-protein-coupled receptors are members of the corticotropin releasing factor (CRF) receptor subfamily. We have previously reported that one of these receptors, encoded by CG8422 is a functional receptor for a diuretic hormone, DH(44). Here, we report that the other CRF receptor subfamily member, encoded by CG12370, is also a receptor for the DH(44) neuropeptide. The ...

OBJECTIVE To describe the clinical patterns of arthritis in psoriasis. STUDY DESIGN Cross-sectional, observational study. PLACE AND DURATION OF STUDY Combined Military Hospital, Kharian Cantonment, Pakistan, from January to December 2007. METHODOLOGY One hundred consecutive patients with psoriasis reporting to dermatology outpatient department were included. Pregnant ladies (due to X-ray ...

Genetic factors influence renal disease progression, and several loci have been linked to the spontaneous development of proteinuria and glomerulosclerosis in animal models. However, the role of genetic susceptibility in glomerulonephritis-induced progressive glomerulosclerosis is unknown. In a rat model of mesangial proliferative glomerulonephritis, anti-Thy-1 glomerulonephritis (antiThy1GN), ...

hypersensitivity reactions to natural rubber latex have increased recently, especially among people with high exposure to latex allergens. hypersensitivity reactions to latex are related to many conditions like occupational asthma. our study was performed to determine the prevalence of hypersensitivity to natural rubber latex and potential food cross reactions in operation room personnel in shi...

Lucas and Moll have proposed a system of forward-backward partial differential equations that model knowledge diffusion economic growth. It arises from microscopic learning for mean-field type interacting individual agents. In this paper, we prove existence traveling wave solutions to system. They correspond what is known in economics as balanced growth path solutions. We also study the depende...

Any valid Ramsey statement n −→ (k)2 can be encoded into a DNF formula RAM(n, k) of size O(nk) and with terms of size (k 2 ) . Let rk be the minimal n for which the statement holds. We prove that RAM(rk, k) requires exponential size constant depth Frege systems, answering a problem of Krishnamurthy and Moll [15]. As a consequence of Pudlák’s work in bounded arithmetic [19] it is known that ther...

©FSRH J Fam Plann Reprod Health Care 2010: 36(2) Society prostitution Logic, science and a whole new range of philosophies arrived in Great Britain alongside George I who ascended the throne in 1714. There were more than 50 Catholics who had a greater right to the throne than George, but Britain would not tolerate another Catholic – however close to the throne. The non-English-speaking German w...

In this study, two cardioactive drugs, acetylcholine (ACh) and the tetrapeptide FMRFamide, are perfused through the isolated systemic heart of the gastropod, Busycon canaliculatum. Their effect is examined in terms of the regulation of output, and is then related to the in vivo regulation of stroke volume. ACh decreases cardiac output by reducing both stroke volume and heart rate. End-diastolic...
