The automotive, aerospace and marine industries make extensive use of aluminum and its alloys to produce a wide variety of components.This prompts research work related to improving manufacturing processes using these materials.One of the main problems in this area is the durability of cutting tools.This article describes the results of tests on th
Prostatic carcinoma whose initial manifestation was a tumor of external auditory canal
Background: Metastatic carcinoma manifesting as a mass in external auditory canal (EAC) is pica limon packets very rare, and prostatic adenocarcinoma (PA) presenting firstly as a mass of EAC has not been reported.Aim: To report a case of PA manifesting as only a mass of EAC.Case report: A 77-year-old man presented a right EAC mass.Otoscope identifi
Optimal three-dimensional biped walking pattern generation based on geodesics
The innovative three-dimensional humanoid biped gait planning method using geodesics is introduced in this article.In order to control three-dimensional walking, the three-dimensional linear inverted pendulum model is studied in our energy-optimal gait planning based on geodesics.The kinetic energy of the three-dimensional linear inverted pendulum
Two managerial public relations roles in the South African context
This article reports the findings of Stage 3 of an international collaborative research programme, its point of departure being that public relations (PR) fuchsia velvet tablecloth roles researchers have largely ignored research in the management domain in their conceptualisation of the PR manager role.(The first qualitative stage was conducted in
Transport Pathways That Contribute to the Cellular Distribution of Phosphatidylserine
Phosphatidylserine (PS) is a negatively charged phospholipid that displays a highly uneven distribution within cellular membranes, essential for establishment of cell polarity and other processes.In this review, we discuss how combined action of PS biosynthesis enzymes in the endoplasmic reticulum (ER), medline k4 basic wheelchair lipid transfer pr
