A study was conducted of the fire ignition potential of high-speed disk cutting saws (hotsaws). Surface temperature increases for the operating saw blade were measured during normal cutting and when stopping the disk using friction against a stump. Observed temperature increases during normal operation were as high as 17◦ C above ambient. Tooth temperatures tended to be highest, but were not ob...

OBJECTIVE To determine, by means of comparative biomechanical tests, whether greater compressive load resistance and flexion is presented by 95° angled blade plates or by dynamic condylar screws (DCS), and to correlate the failure type presented during the tests with each type of plate. METHODS Sixty-five porcine femurs were subjected to 1 cm medial wedge osteotomy, in the metaphysis, to simu...

The influence of soil parameters and weeder design on implement performance is discussed. Soil parameters that are important in this context are cohesion, adhesion and internal friction. Important weeder design parameters are blade angles of attack and approach, blade overlap and blade support configuration. An example of an animal-drawn weeder developed in Mexico is analysed. An evaluation of ...

Parameters of iron uptake have been determined for blade tissue of Macrocystis pyrifera (L.) C. Ag. These include the effects of iron concentration, light, various inhibitors, and blade type. All experiments were conducted in the defined artificial seawater Aquil. Iron uptake is light independent, energy dependent, and dependent on the reduction from Fe(3+) to Fe(2+). Iron is concentrated in th...

We propose a blind multiuser detection technique for array processing and code division multiple access (CDMA) systems that does not require knowledge of the array geometry or transmitter signature sequences. The technique has two key elements: an adaptive algorithm for separating the signal subspace from the noise subspace and an adaptive whitener based on linear prediction. The proposed algor...

Since the clinical introduction of proximal femoral nail antirotation (PFNA) by AO group in 2004 and PFNA-II (Asian version) in 2008, this type of cephalomedullary nail with single head-neck helical blade were commonly used in unstable pertrochanteric and intertrochanteric fractures in geriatric patients. Recently, severe complications of helical blade perforation through the femoral head, into...

This paper presents the lubrication characteristics between a bush and a blade of a swing compressor that was developed for a new type of compressor for an air conditioner using alternative refrigerants. The mixed lubrication analysis that simultaneously solved the motion equations of the bush and the blade, the lubrication equation and the rough surface contact equation was performed. Moreover...
