AIM To compare the burning characteristics of the tobacco and paper of manufactured and hand rolled cigarettes, and set a fire safety standard of manufacture to largely reduce the fire risk from discarded cigarettes. METHODS (1) Cigarette extinction test of ignition strength: 40 cigarettes per brand, lit and placed on 15 layers of filter paper, in accordance with ASTM test standard E2187-02. ...
Thurid Gspann said: There appears to be a length issue when dealing with carbon nanotubes. On the one hand for most applications, mechanical as well as electrical, CNT ends represent the ultimate defect. In other words CNTs should be as long as possible. On the other hand, purication, solubilisation and separation processes either shorten CNTs or require them to be of a length usually less tha...
BACKGROUND The purpose of this study was to investigate the consistency of working length control between hand instrumentation in comparison to engine driven Mtwo nickel-titanium rotary files. MATERIAL AND METHODS Forty extracted maxillary molars were selected and divided onto two parallel groups. The working lengths of the mesiobuccal root canals were estimated. The teeth were fixed in a pha...
Materials and Methods: 238 males and 259 females in the age group of 18-30 year were considered for measurements: height, hand morphometrics and foot morphometrics. Stadiometer was used to measure the height. All morphometric measurements analyzed by SPSS. Results: In females, stature varied from 140.500 to 180.00 cm with mean value of 157.199±6.244 cm. In males, stature varied from 159.00 to 1...
A sample of 166 normal adult males and females was taken from different colleges of Assiut representing those living in upper Egypt. Each subject has been studied for measurements of stature (S), hand length (HL) and hand breadth (HB). The data were statistically analysed in order to assess the relationship between stature and hand measurements. The correlation matrix of the study indicates clo...
Handedness is likely to be controlled by many genetic variants, some of which are in sex-dependent genes that also influence body asymmetry. One such asymmetry may be in foot length. Levy and Levy (Science, 200, 1291– 1292, 1978) reported that right-handed males have longer right feet than left and left-handed males have longer left feet than right, while this trend was found to be reversed in ...
This paper applies dimensional synthesis to explore the geometric design of dexterous three-fingered robotic hands for maximizing precision manipulation workspace, in which the hand stably moves an object with respect to the palm of the hand, with contacts only on the fingertips. We focus primarily on the tripod grasp, which is the most commonly used grasp for precision manipulation. We systema...
