A supramolecular combination of carbon nanotube and fullerene, so-called a peapod, has attracted much interest, not solely because of its physical properties but also for its unique assembled structures of carbonaceous entities. However, the detailed structural information available was not sufficient for in-depth understanding of its structural chemistry or for exploratory research inspired by...

PURPOSE Fatigue is the most common and distressing symptom reported by cancer patients during and after treatment. Tumor growth increases oxidative stress and cytokine production, which causes skeletal muscle wasting and cardiac dysfunction. The purpose of this study was to determine whether treatment with the antioxidant ubiquinol improves muscle mass, cardiac function, and behavioral measures...

HTLV-I is a transforming human retrovirus that is an etiologic agent of adult T cell leukemia/lymphoma. To investigate the effects of this virus on T cell functions, two OKT3+, OKT4+, KI8cytotoxic clones (8.7 and 8.8) specific for allogeneic cells bearing DPw2, a class II histocompatibility antigen, were studied before and after infection with HTLV-I. The clones retained cytotoxic function for ...

In the present study, we investigated the in vitro and in vivo antitumor effects of crude extract of Scutellaria Barbate (CE-SB) on mouse hepatoma H22 cells. The MTT assay was used to determine the growth inhibition of H22 cells in vitro. The in vivo therapeutic effects of CE-SB were determined using H22 tumor bearing mice. Besides, the body weight, tumor weight, thymus index and spleen index o...

Large mechanical equipment is subject to periodic vibrations in harsh operating environments for a long time. Bearing failure produces violent changes the behaviors of large rotating machinery as safety and reliability scene. Therefore, it especially significant effectively identify early bearing. Since signal bearing fault belongs low-frequency weak fault, hard classify characteristic frequenc...

Lightweight structures capable of changing their shape on demand are of interest for a number of applications, including aerospace, power generation, and undersea vehicles. This paper describes a bioinspired cellular metal vertebrate structure which relies on shape memory alloy (SMA) faces to achieve fully reversing shape change. The resulting vertebrate actuators can be combined with flexible ...

Joints are failure points for deployable systems and moving devices. Their reliability and efficiency are of great concern for space applications. In this paper we present a new biologically inspired joint for space applications that has a minimal number of parts and requires no bearings. Its principle is based on a compliant structure that changes shape with Shape Memory Alloy actuators. An ex...

HTLV-I is a transforming human retrovirus that is an etiologic agent of adult T cell leukemia/lymphoma. To investigate the effects of this virus on T cell functions, two OKT3+, OKT4+, OKT8- cytotoxic clones (8.7 and 8.8) specific for allogeneic cells bearing DPw2, a class II histocompatibility antigen, were studied before and after infection with HTLV-I. The clones retained cytotoxic function f...

Usually magnetic bearing consists of an actuator and a levitated object which can be either the rotor of a motor or any other ferromagnetic body. For proper function and to provide stable support, the actuator needs an accurate information about the position of the levitated body which must be given by a sensor. In many applications the displacement sensor with associated wires and cost to be a...

A novel idea of using giant magnetostrictive material (GMM) based actuators for journal bearing control is presented in this paper. Frequency response tests on GMM actuators and a journal bearing system were examined. The performances of the system running at various journal shaft rotational speeds under control were investigated. With the aid of GMM actuators, the performances on journal shaft...
