The wood industry faces the dual requirements of improving quality timber products and minimising waste during manufacturing process. finger joint, which is an end-to-end joining method for boards, one most important aspects engineering products. This study presents a numerical optimisation investigation effects finger-joint design parameters on flexural behaviour finger-jointed beams. A model ...

Heparin and heparan sulfate have recently been shown to bind to snake cardiotoxin (CTX) and to potentiate its penetration into phospholipid monolayer under physiological ionic conditions. Herein we analyze the heparin-binding domain of CTX using 10 CTXs from Taiwan and African cobra venom. We also performed computer modeling to obtain more information of the binding at molecular level. The resu...

Excision of the trapezium with Gelfoam interposition was performed in 35 thumbs, 34 of which were evaluated after an average 5 years. Twenty-four patients had unilateral procedures. The follow-up examination included a standardized questionnaire and clinical and radiological examinations. Pain relief was achieved in all cases. The patients considered that 32 of their operated hands had improved...

DESCRIPTION A 44-year-old man, right hand dominant, presented to the emergency department with a chief complaint of left hand pain status post crush injury to left hand between heavy metal objects at the workplace. The patient was found to have a left long finger distal tip amputation with concomitant transverse distal phalangeal fracture and intact sterile and germinal matrix.

When performing a goal-directed action with a tool, it is generally assumed that the point of control of the action system is displaced from the hand to the tool, implying that body and tool function as one system. Studies of how actions with tools are performed have been limited to studying either end-effector kinematics or joint-angle coordination patterns. Because joint-angle coordination pa...

Time series of sensor databases and scientific time series often consist of periodic patterns. Examples can be found in environmental analysis, where repeated measurements of climatic attributes like temperature, humidity or barometric pressure are taken. Depending on season-specific meteorological influences, curves of consecutive days can be strongly related to each other, whereas days of dif...

Qualitative and quantitative performance on the Halstead Finger Tapping test may help differentiate brain dysfunctional patients from normal controls. "Normal" and "abnormal" finger tapping patterns during this task have been characterized and illustrated pictorially. Data from 65 patients with traumatic brain injury (TBI) and 15 normal controls support the dual proposition that (1) abnormal fi...

Complicated nano-patterns with linewidth less than 18 nm can be automatically hammered by using atomic force microscopy (AFM) tip in tapping mode with high speed. In this study, the special sample was thin poly(styrene-ethylene/butylenes-styrene) (SEBS) block copolymer film with hexagonal spherical microstructures. An ordinary silicon tip was used as a nano-hammer, and the entire hammering proc...

In recent years, there has been great interest in the possibility of using artificial limbs as an extension of the human body as well as replacement of lost limbs. In this paper, we develop a sixth finger system as an extension of the human body. We then investigate how an extra robotic thumb, that works as a sixth finger and gives somatosensory feedback to the user, modifies the body schema, a...

Six Iranian populations have been analyzed for finger patterns, utilizing bilateral prints of 720 individuals. Bimanual and sex differences were frequently insignificant and non-significant. Interpopulational variation showed significant hetererogeneity among the populations studied. Distance analysis and constructed dendrograms, based on these six populations and other thirteen Iranian populat...
