1. First, wire up the circuit as shown in the diagram above, with the resistor, inductor, and capacitor connected in series to one another and the signal generator. Use the output of the Science Workshop 750 as the signal generator. 2. Start with the following values for resistance, inductance, and capacitance: • R = 500 Ω; L = 100 mH = 0.1 H; C = 1 μF = 1 x 10 F 3. Throughout the experiment yo...

An experimental investigation with Nd:YAG laser system was carried out to study the effects of laser hardening process parameters on the microstructure and hardness during laser hardening of EN25 steel. The laser beam is allowed to scan on the surface of the work piece by varying the laser beam power (750–1250 W) and travel speed (500–1000 mm/min) of the work table. The microstructural features...

A s s e s s m e n t o f p r o g n o s t i c f a c t o r s 3 weeks after stopping OAT, laboratory testing was done to determine the levels of D-dimer (measured by an enzyme-linked immunoassay [Asserachrom D-dimer, Boehringer Mannheim, Mannheim, Germany]), antithrombin, protein C, protein S, factor VIII, the lupus anticoagulant, factor V Leiden, and factor II G20210A. Levels of D-dimer were class...

It has been estimated that one child in 500 to 750 live births is born with a cleft palate (Rood & Stool, 1981). A high incidence of middle ear pathology is known to be associated with this problem (Bluestone, 1971). It is generally accepted that this population suffers from Eustachian tube dysfunction which leads in turn to the development of middle ear effusions and conductive hearing loss. T...

We report the demonstration of a diode-pumped chirped pulse amplification Yb:YAG laser that produces λ=1.03  μm pulses of up to 1.5 J energy compressible to sub-5 ps duration at a repetition rate of 500 Hz (750 W average power). Amplification to high energy takes place in cryogenically cooled Yb:YAG active mirrors designed for kilowatt average power laser operation. This compact laser system wi...

We develop an uncertainty analysis that captures the dominant sources of measurement error in state-of-the-art WM-380 (WR 1.5) rectangular-waveguide vector-network-analyzer measurements over the frequency range 500–750 GHz. We use the analysis to assess thru-reflect-line, thru-short-match, and thru-short-radiating-open calibrations. The comparison shows that thru-short-match and thru-short-radi...

Objectives: To obtain evidence for dose response and to extend evidence of safety and efficacy for B lymphocyte depletion in rheumatoid arthritis. Methods: Twenty two patients with rheumatoid arthritis received a total of 29 treatments with five different combinations of rituximab (RTX), cyclophosphamide (CP), and/or high dose prednisolone (PR) on an open basis as follows; cohort I: RTX 1400 mg...

Combining intracellular electrophysiology and multi-photon calcium imaging in vivo, we studied the relationship between calcium signals (sampled at 500-750 Hz) and spike output in principal neurons in the locust antennal lobe. Our goal was to determine whether the firing rate of individual neurons can be estimated in vivo with calcium imaging and, if so, to measure directly the accuracy and res...

A bi-dimensional geometrical model was developed and numerically solved considering different cylindrical tungsten specimens, heated to temperatures above 3600 Kwith current pulses of about (500, 750, and 950) ms duration. A detailed analysis of these virtual experiments indicated large radial temperature differences in all the investigated cases. The range of validity of the long thin rod appr...
