Plasma immersion ion implantation from a BF3 plasma into crystalline (100) silicon was performed using the PULSION plasma doping tool. Implanted boron profiles were measured with the SIMS method and simulated using models with different levels of sophistication. The physical implantation model is based on an analytical energy distribution for ions from the plasma and uses a Monte-Carlo simulati...
in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...
Zinc-containing β-tricalcium phosphate (ZnTCP) nano particles were injected into zinc-deficient rats to promote osteogenesis. Sprague-Dawley (SD) rats (4 weeks old, average weight of 70 g) were divided into four groups: Normal rats (not ovariectomized (OVX)), Control rats (OVX), and OVX rats injected with a suspension of ZnTCP nano particles or ZnSO(4). The ZnTCP contained 6.17% zinc. The suspe...
Brittle solder joints in Electroless Ni electroless Pd immersion Au (ENEPIG) surface finishes are one of the key re liability issues in electronics assembly. Previous characterization of the reflow process has indicated that interfa cial voids formed after solder reflow are responsible for the decreases in solder joint strength. However, the mechanisms behind the formation of these voids in t...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
Abstract In order to obtain the full flow passage characteristics of suction chamber and internal rotor double rectangular screw pump, based on immersed solid method, using CFD simulation platform, transient numerical typical design conditions pump with given basic parameters is carried out by N-S equation SST Turbulence Model, during operation are obtained. The shows that pressure fluctuation ...
sugar beet yield and quality characteristics as affected by magnetic field and silver nano particles
in order to study the effects of magnetic field, silver nano particles and micronutrient fertilizers on sugar beet, an experiment was conducted at razavi research and technology institute, mashhad, iran. experiment carried out with seven treatments based on randomized complete block design with three replications. treatments included (t1) magnetic field and silver nano particles + kemira fertil...
