An important tool for biological research and microsurgery is a microdevice for the cutting and isolation of subcellular neuronal components such as axons and dendrites for analysis or microsurgery. We have fabricated an easy-to-use, inexpensive and robust MEMS device with a nanoscale cutting tool that performs highly reproducible cutting of axons and dendrites. The device consists of a knife w...
Abstract The paper presents a structure diagram of slot trencher when planting garden, consisting frame on which working sections, bevel gear reducer and support wheel stands are fixed. On the section there is shaft with body - disk cutter. It made in form disc teeth, one cutting edge each tooth straight other parabolic. parabolic elements fixed knives two parts. A along periphery; guide entire...
OBJECTIVE In this investigation the thickness of enamel in the gingival, middle, and incisal thirds of the labial surface of the anterior teeth were measured regarding preparation of the teeth for porcelain laminate veneers. MATERIALS AND METHODS Part one, 20 extracted intact human maxillary central and lateral incisors ten of each were selected. The teeth were imbedded in autopolimerize acry...
Proton range monitoring may facilitate online adaptive proton therapy and improve treatment outcomes. Imaging of proton-induced prompt gamma (PG) rays using a knife-edge slit collimator is currently under investigation as a potential tool for real-time proton range monitoring. A major challenge in collimated PG imaging is the suppression of neutron-induced background counts. In this work, we pr...
This paper addresses the problem of motion Chaplygin sleigh, a rigid body moving with three points in contact horizontal plane. One them is equipped knife edge along which there no slipping. Special attention given to case where dry friction present at one support without edge. The equations are written, normal reactions calculated, and behavior phase curves neighborhood an equilibrium point, d...
Invited for the cover of this issue are Abhik Ghosh and his collaborators at UiT (The Arctic University of Norway, Tromsø) and in the United States. The image depicts a silver corrole complex poised on the summit ridge of Mount Sir Alexander, a peak of the Canadian Rockies (image courtesy of Chris Goulet), symbolizing the balance between innocent and noninnocent ligands.
