Uganda is dominated by agriculture with over 80 percent of the 24.6 million people involved in subsistence farming. The most important cereals are maize, finger millet and sorghum in that order. Finger millet is the second most important cereal in Uganda after maize and exceeding sorghum both in area and production. It is the staple food for over 50% of the country’s 24.6 million people and inc...

Magnetic reconnection is a universal process that powers explosive energy-release events such as solar flares, geomagnetic substorms and some astrophysical jets. A characteristic feature of magnetic the production fast outflow jets near plasma Alfvén speeds1,2. In eruptive dark finger-shaped downflows moving toward flare arcade have been commonly regarded principal observational evidence for re...

The preceding study demonstrated that normal subjects compensate for the additional interaction torques generated when a reaching movement is made during voluntary trunk rotation. The present paper assesses the influence of trunk rotation on finger trajectories and on interjoint coordination and determines whether simultaneous turn-and-reach movements are most simply described relative to a tru...

The very light contact forces (∼0.60 N) applied by the fingertips during tactile exploration reveal a clearly optimized sensorimotor strategy. To investigate the cortical mechanisms involved with this behavior, we recorded 230 neurons in the somatosensory cortex (S1), as two monkeys scanned different surfaces with the fingertips in search of a tactile target without visual feedback. During the ...

Understanding how fingers slip on surfaces is essential for elucidating the mechanisms of haptic perception. This paper describes an investigation of the relationship between occlusion and the non-Coulombic slip of the finger pad, which results in the frictional force being a power law function of the normal load, with an index ; Coulombic slip corresponds to = 1. For smooth impermeable surface...

Metal complexes that bind to DNA on the basis of shape-selection have been used to map the conformational features of the DNA binding site for transcription factor IIIA. Conformationally distinct segments are detected on the 5S rRNA gene that correspond closely to the binding sites identified for the individual zinc finger domains of the protein. The local conformations are characterized by a m...

By carefully positioning the bow and a lightly touching finger on the string, the string spectrum can be conditioned to provide narrow bands of pronounced energy. This leaves the impression of multiple complex tones with the normal (Helmholtz) fundamental as the lowest pitch. The phenomenon is seen to be caused by two additional signal loops, one on each side of the finger, which through the re...

-----------------------------------------------------------ABSTRACT----------------------------------------------------------Biometric traits are now highly explored by researchers to establish a system that can be used to accurately identify a person. Personal identification based on biometric features is becoming more popular these days because it is more reliable than traditional methods and...

Three studies of different mobile-device hand postures are presented. The first study measures the performance of postures in Fitts’ law tasks using one and two hands, thumbs and index fingers, horizontal and vertical movements, and frontand back-of-device interaction. Results indicate that the index finger performs well on both the front and the back of the device, and that thumb performance o...
