This paper derived the surface profile equations and the Arm Chair meshing equations of the spherical meshing elements from the homogeneous coordinate transformation matrix and the conjugate surface theory proved by the envelope theory.In the machining aspect, we demonstrated the position equation of cam profile using the coordinate transformation
Evolutionary algorithms (EAs) simulate Darwinian evolution and adeptly mimic natural evolution.Most EA applications in biology encode high levels of abstraction in top-down population ecology models.In contrast, our research merges protein alignment algorithms from bioinformatics into codon based EAs that simulate molecular protein string evolution
Abstract Background A wide range of foreign bodies has been retrieved from the gut and Parts reported.The presentation may be in the form of complications like intestinal obstruction, perforation and formation of abscesses etc but there is no case report of a half open clasp knife being retrieved from the ileum, the patient having thrived, in spite
Alopecia (loss of volume or complete loss of hair) can be a symptom of many diseases.In some cases it is a symptom of a local pathology limited to the scalp, in others it is a dermatological symptom of a systemic pathology.In almost every case, alopecia has a significant impact on the quality of life and may Magnetic Drain Pump cause limitations in
This case series describes transoral penetrating or contusive medullocervical injury by a wooden chopstick in Switches three young cats presenting with acute tetraparesis.CT revealed that remnant fragments of a wooden chopstick penetrated the atlantooccipital space in cases 1 and 2.The remnant fragments were visualized clearly on CT under the bone
