Under experimental conditions with HRT for 4 hours, and aeration time and non-aeration time for 90 min/30 min, the average removal ratios of DOC, COD_(Cr), NH_4-N, T-N and T-P with the oxidation ditch MBR were 75%,90%,95%,80% and 50%.
The test results showed that as remelting using 75CaF_2-15Al_2O_3-10CaO pure ternary slag the Ti burning loss rate was 7.0%,lowest in 4 slag systems and free slag groove of ingot surface which occurred as remelting using 70CaF_2-30Al_2O_3 binary slag
The ratios of diameters of the spinal nerves to the width of the internal opening of the spinal nerve sulcus were 1∶2.15 for C 3, 1∶2.05 for C 4, 1∶1.98 for C 5, 1∶1.14 for C 6, 1∶1.18 for C 7 respectively.
②The total rate of occurrence was 6.3%for wedge pressure of anterior branch of cervical spinal nerve in sulcus in spinal nerve for both male and female, of which, that of male was remarkably superior to the female(8.9%, 3.9%, χ2=6.65,P< 0.01).
Ditch reed (Phragmites australis) and alfalfa (Medicago sativa) markedly intensified processes of pollutant destruction, the effect being particularly pronounced in the case of polycyclic aromatic hydrocarbons.
Results from parametric studies on investigating enhancement of heat transfer by means of cavity-and ditch-shaped tornado-like intensifiers are presented.
This indicated that among environmental water sources, the ditch iodine content was the highest with river water iodine being the lowest (P>amp;lt;0.01).
The survey reveals that almost all the clumps (98%) are located in the pond and ditch site and around half of the clumps (48%) are found in the western site of the homesteads.
There were 9 positive from 30 samples of pond-ditch water in high endemic county-Haimen by high-peformance liquid chromatograph and 3 already confirmed by liquid chromograph/mass spectrometer.
Based on MD simulation, nanometric-grinding mechanism is analyzed from the viewpoint of instantaneous distribution of atoms, grinding force, and the potential energy between atoms and the profile of the groove.
The good agreement in the profile of the groove between the experimental value and the simulating value shows that MD simulation is very effective and reliable, and successful to fulfill the investigation on nanometric machining mechanism.
A laser vision sensing based on the adaptive tungsten inert gas (TIG) welding system for large-scale aluminum alloy components was established to fit various weld groove conditions.
A new type of laser vision sensor was used to precisely measure the weld groove.
An adaptive welding process was realized by automatically adjusting the wire feeding speed and the welding current according to the groove conditions.
Aliasing error bounds are derived for one- and two-channel sampling series analogous to the Whittaker-Kotel'nikov-Shannon series, and for the multi-band sampling series, and a "derivative" extension of it, due to Dodson, Beaty, et al.
Aliasing in the one-channel case is shown to arise from a transformation with similarities to a projection.
An Estimation of the Truncation Error for the Two-Channel Sampling Formulas
Guanidine-type compounds that reached clinical status include amongst others the potassium channel opener, pinacidil and the histamine H2-receptor antagonists (e.g.
The tetra-n-butylammonium cations were stacked to give two columns within each channel with cross-sectional size of about 2.30 nm × 0.93 nm.
Although dehydrated pollen grains appear monosulcate, the study of hydrated pollen shows that the aperture occupies nearly half of the pollen surface and represents a pore rather than a sulcus.
At right thoracotomy (halothane anesthesia), mongrel dogs had bipolar electrodes sutured to the epicardial surface of both atrial appendages, juctions of the sulcus terminalis with both vena cavae, and right ventricle.
Es kann mit Hilfe der Vertebralisangiographie nachgewiesen werden, da? als Pr?dilektionsstelle für diese arteriellen Gef??erkrankungen der hinteren Sch?delgrube der Sulcus arteriae vertebralis atlantis in erster Linie in Betracht kommt.
flexor carpi ulnaris, especially of the distal latency (stimulation point 2 cm above the sulcus ulnaris) to this muscle, represents a valid procedure for the localisation of an ulnar nerve lesion at the elbow.
Right carotid angiography revealed an early-filling vein near the right central sulcus.
