An electron microscope study was made of Deltotrichonympha and Koruga, two closely-related hypermastigote flagellates that live in the hindgut of the Australian termite, Mastotermes darwiniensis These symbiotic protozoans have a typical flagellated rostrum and long body flagella. Their "giant centrioles" (centriolar apparatus) are large, fibrillar, and granular bodies which do not resemble typi...

In this paper we aim to create an experimental and numerical model of nano and micro filaments suspended in a confined Poiseuille flow. The experimental data obtained for short nanofibres will help to elucidate fundamental questions concerning mobility and deformation of biological macromolecules due to hydrodynamic stresses from the surrounding fluid motion. Nanofibres used in the experiments ...

The discontinuous gas exchange cycle of the pseudoscorpion Garypus californicus, mean mass 5.9 mg, is rudimentary and is characterized by bursts of CO(2) at frequencies ranging from 3.6 mHz at 15 degrees C to 13.3 mHz at 35 degrees C. The mean volume of CO(2) emitted per burst is 3.6 micro l g(-1) at 25 degrees C, about a tenth of the amount emitted by tracheate arthropods with a well developed...

How to meet the technological challenges of designing customized products? Typical customer products, such as shoes, seem to have a simple product structure and a quite low level of complexity. At least if one considers products, such as cars or airplanes. Modern truck factories customize and manufacture trucks, just in time and without being one truck similar to the other. How about shoes? Sho...

1. Methods have been developed for the extraction and purification of bacterial basic proteins. These proteins were initially examined by a micro-method of starch-gel electrophoresis and were then characterized more fully. 2. Although it was found that most of the DNA in both Bacillus megaterium and Escherichia coli must be free from combination with basic protein, there was some evidence that ...

In article number 2000916, Jun Chen and co-workers present a systematic review on recent approaches utilized to modify triboelectric surfaces with nanostructure patterns for advanced nanogenerators (TENGs). As typical physical modification strategy TENGs, micro-/nano-arrays can increase the output voltage current of TENGs significantly through increasing contact area paired surfaces.

waterwheels are the oldest types of hydraulic machines. these turbines are of relatively simple design, large diameter, low rotational speed and high torques. but applying them as micro hydros of high speed and small diameter is yet to be explored. a micro hydro waterwheel of one meter diameter was designed and manufactured at the iranian  esearc†h organization for science and technology (irost...

A unified scheme for quantum measurement processes is formulated on the basis of Micro-Macro duality as a mathematical expression of the general idea of quantum-classical correspondence. In this formulation, we can naturally accommodate the amplification processes necessary for magnifying quantum state changes at the microscopic end of the probe system into the macroscopically visible motion of...
