BACKGROUND AND PURPOSE Experimental models of osteoporosis in rabbits are useful to investigate anabolic agents because rabbits have an active Haversian remodeling and achieve skeletal maturity quickly. In this study, an experimental model of osteoporosis in rabbits induced by a combination of ovariectomy and glucocorticoid was characterized to provide a(More)
Mentally controlled qi energy can induce crop seeds to sprout and root for several cm within about 20 min. The RAPD method was used to compare treated groups of wheat and pea seeds and their controls using 11 selected primers. Seven primers amplified polymorphisms in wheat seeds and 5 in pea seeds. It was thought preliminarily that qi energy changed the(More)
The main purpose of this research is to analyze the performance of an evaporator for the organic Rankine cycle (ORC) system and discuss the influence of the evaporator on the operating characteristics of diesel engine. A simulation model of fin-and-tube evaporator of the ORC system is established by using Fluent software. Then, the flow and heat transfer(More)
This paper presents an 8th order active-RC elliptic low-pass filter (LPF) for a direct conversion China Mobile Multimedia Broadcasting (CMMB) tuner with a 1 or 4 MHz –3 dB cutoff frequency (f 3dB/. By using a novel gain-bandwidth-product (GBW) extension technique in designing the operational amplifiers (op-amps), the proposed filter achieves 71 dB stop-band(More)
One way to increase the thermal efficiency of vehicle diesel engines is to recover waste heat by using an organic Rankine cycle (ORC) system. Tests were conducted to study the running performances of diesel engines in the whole operating range. The law of variation of the exhaust energy rate under various engine operating conditions was also analyzed. A(More)
This paper aimed at functional requirements with CRAC (computer room air conditioning) inverter test system, and realized the test system hardware platform design, while completing the software functional design and programming algorithm. For example in Self-Made 10Kw inverter and Schneider ATV31H 2.2Kw inverter, we research on its output three-phase(More)
Objective: To study the characteristics and stability of new S(-) pantoprazole sodium hydrates. Methods: The X-ray single crystal diffractometer (SXRD), X-ray powder diffractometer (PXRD), thermogravimetric analysis (TG) and infrared spectrometry (IR) were used to characterize S(-) pantoprazole sodium hydrates. The stability of the hydrates was evaluated by(More)
Huge amount of low-grade heat energy is discharged to the environment by vehicular engines. Considering the large number of vehicles in the world, such waste energy makes great impacts to our environment globally. Organic Rankine Cycle (ORC), which uses an organic fluid with a low boiling point working medium, is considered as the most promising technology(More)
A continuous-time 7th-order Butterworth Gm–C low pass filter (LPF) with on-chip automatic tuning circuit has been implemented for a direct conversion DBS tuner in 0.35 μm SiGe BiCMOS technology. The filter’s −3 dB cutoff frequency f0 can be tuned from 4 to 40 MHz. A novel on-chip automatic tuning scheme has been successfully realized to tune and lock the(More)
