Human survival requires quick and accurate movements, both with and without tools. To overcome the sensorimotor delays and noise, the brain uses internal forward models to predict the sensory consequences of an action. Here, we investigated whether these sensory predictions are computed similarly for actions involving hand-held tools and natural hand movements. We hypothesized that the predicti...

The pathogenic events and the localization of the primary lesion in white fingers among persons using hand-held vibrating tools are still unclarified. A "vibration disease" has been proposed to be due to damage to the limbic system and other brain structures which causes autonomic dysfunction. Current common opinion regards the pathogenesis of white fingers to be a result of longterm exposure t...

The perception of object-directed actions performed by either hands or tools recruits regions in left fronto-parietal cortex. Here, using functional MRI (fMRI), we tested whether the common role of hands and tools in object manipulation is also reflected in the distribution of response patterns to these categories in visual cortex. In two experiments we found that static pictures of hands and t...

OBJECTIVES To explore the ability of six outcome measures to capture clinically important changes in patients with rheumatic diseases undergoing hand surgery and to study predictors of changes in activity performance in different patient and surgery strata. METHODS A total of 172 patients (median age 59 years, disease duration 18 years) were stratified into subgroups: diagnosis, age, general ...

Occupational noise has been recognized as hazardous for the human beings. A high noise level in forging shops is considered to lower the labour productivity and cause illness however occupational noise is being accepted as an integral part of the job. The present study has been carried out in 5 small scale hand tool forging units (SSI) of different sizes in Northern India in Punjab. Noise level...

Most countries in resource-poor, malaria-endemic areas lack current and comprehensive information on antimalarial drug efficacy, resulting in sub-optimal antimalarial treatment policies. Many African countries continue to use chloroquine despite very high rates of resistance, and others have changed policies based on limited data, with mixed success. Methods for measuring antimalarial drug effi...

The visual fidelity (fidelity) of a design diagram affects perception and design performance. Hand-drawn diagrams are more effective working documents for early design tasks such as user interface designs than the equivalent computer-prepared formal representation. However people prefer more formal representations because they feel that hand-drawn diagrams look unprofessional. Sketch-based desi...

Ewing's sarcoma (ES) is a highly malignant neoplasm of childhood and adolescence seen commonly in both axial and appendicular skeleton but uncommonly in acral region. Ewing’s tumor in the hand is extraordinarily rare. Radiological features are variable and can mimic other common lesions. We present a case of 13 year old female, with complaints of pain and swelling in right hand, which on X-ray ...

This study explored whether functional properties of the hand and tools influence the allocation of spatial attention. In four experiments that used a visual-orienting paradigm with predictable lateral cues, hands or tools were placed near potential target locations. Results showed that targets appearing in the hand's grasping space (i.e., near the palm) and the rake's raking space (i.e., near ...

Data Mining is a process of automatic searching large data set to discover patterns and trends; those are used for sophisticated analysis after applying statistical and mathematical algorithms to determine meaningful data and the prognostication of future events and trends. The existing trends of application and tools of data mining can fulfill the need of any enterprise; but with location depe...
