Auger drilling tool is widely used in mining, exploration and security and other fields, is an important part of mine equipment, aiming at the best cutting speed and conveying speed of drill tool mismatch.In this paper, a new type of separated drill tool structure is proposed to realize the independent control of the bit cutting speed and the drill
It is known that total telomere length is shorter in invasive breast cancer than in normal breast tissue but the status of individual telomere lengths has not been studied.Part of the difficulty is that usually telomere length in interphase cells is measured on all chromosomes together.In this study we compared normal breast epithelium, duct carcin
There is a growing interest in the use of Autonomous Underwater Vehicles (AUVs) and Underwater Sensor Networks (USNs) for scientific, military, and industrial applications, leading to the development of wireless underwater communications.However, the channel for Underwater Acoustic (UWA) communications is challenging compared to the radio wave prop
The study was conducted at Bangladesh Agricultural Research Institute (BARI) farm on clay loam soil during Rabi season of 2010-2011.The treatments consisted of laser land leveling (T1) and control (non-leveled) (T2).A preliminary field survey was done using staff gage.Initially a base station was established to dispense laser ray uniformly.The lase
BackgroundCurrently, vaccination of livestock with attenuated strains of Brucella remains an essential measure for controlling brucellosis, although these vaccines may be dangerous to humans.The aim of this study was to review the risk posed to humans by occupational exposure to vaccine strains and the measures that should be implemented to minimiz
