Low Frequency isolation

In this paper, an isolator is introduced for isolating low frequency vibrations. Then, Normal form method is used to predict the curve of vibration transmissibility of this isolator. This paper is organized as follows. The mathematical model of system is presented in section.

This study has adopted a systematic approach to identify the extent to which 20 kHz ultrasound affects the particle size and solubility of different protein solutions containing 4%, 7% and 10% whey proteins, caseins or a mixture at a range of energy densities (15-400 J/mL) and various pH (4.0-9.0). Milk proteins hold a prominent place in the food industry as they are used in many manufactured products for their functionality and most importantly nutritional benefits.

This paper presents a low-stiffness nonlinear vibration isolator using a pneumatic spring with an auxiliary chamber which is shortened by LSNVI. Firstly, the mechanical model of the isolator, which is constructed by two opposite stiffness mechanisms includes the load-bearing mechanism (LBM) and the stiffness-corrected mechanism (SCM), is introduced.

Staging of Small Cell Lung Cancer Pretreatment staging for patients with SCLC includes the initial general lung cancer evaluation with chest and abdominal CT scans (because of the high frequency of hepatic and adrenal involvement) as well as fiberoptic bronchoscopy with washings and biopsies to determine the tumor extent before therapy; brain CT scan (10% of patients have metastases); and radionuclide scans (bone) if symptoms or other findings suggest disease involvement in these areas.
