The shift of Energy levels of a quantum dot in single electron transistor

The shift of Energy levels of a quantum dot in single electron transistor model is investigated. The self-energy function which related to shift of Energy levels, describing this interaction is added to a bare energy of a dot state. In the standard way of determining the self-interaction corrections to bare energies of quantum dots, the variations of the self-energy functions with energy are ignored, and these corrections are considered to be equal to the values of the self-energy functions for bare energies of state

Effects of adding mixed powder of garlic and thyme to diets included graded levels of rice bran on productive performance of laying hens and egg quality characteristics

Code: 6715685418. Mohebbifar, A. and M. Torki; Effects of adding mixed powder of garlic and thyme to diets included graded levels of rice bran on productive performance of laying hens and egg quality characteristics ABSTRACT To investigate the effects of adding dried powder of medicinal plants (MP) including garlic (Allium sativum) and thyme (Thymus vulgaris) to rice bran-included diets on performance of laying hens, egg quality traits and blood differential count of white blood cells, 144 Lohmann LSL-Lite hens after production peak were randomly divided in 24 cages (n=6). Six iso-caloric and iso-nitrogenous experimental diets (ME = 2720 Kcal/ Kg and CP=154.2 g/Kg) including three levels (0, 100 and 200 g/kg) of rice bran (RB) with MP (0 and 2.5 g/kg) were fed hens with 4 replicates per diet during 8-week trial period. In weeks 4 and 8, all produced eggs per each dietary group during three frequent days were collected to measure egg quality traits. To determine blood biochemical parameters and differential count of white blood cells, one randomly selected hen per replicate was bled via wing vein on day 35 of trial. Collected data of feed intake (FI), egg production (EP), egg mass (EM); calculated feed conversion ratio (FCR), egg quality traits and blood parameters in a 3×2 factorial arrangement was analyzed based on completely randomized design using GLM procedure of SAS. Dietary treatment did not have significant effect on EP, EM, FI and FCR of laying hens (P>0.05). Egg weight, egg index, Haugh unit, egg gravity and egg shell weight were not significantly affected by dietary treatment (P>0.05). Yolk color in the first measurement (wk 4) was higher in the control compared to the RB-included dietary group (P=0.02); but, in second egg sampling (wk 8) yolk color was higher in the 200 g RB-included dietary group (P= 0.01) compared the other dietary groups. In second measurement (wk 8) egg shell thickness was higher in the control compared to RB-included dietary groups (P=0.03). Dietary treatment did not have significant effect on feces pH (P> 0.05). From the results of the present study it can be concluded that RB can be included in diets of laying hens up to 20% with no adverse effect on productive performance. In terms of egg quality characteristics, egg shell quality might be improperly affected by dietary RB inclusion. Adding ground mixture of dried garlic and thyme did not have beneficial effects on hens' performance and egg quality

Self-energy function of quantum-dot states and resonance fluorescence

© Published under licence by IOP Publishing Ltd. We investigate the energy dependence of self-energy functions of quantum-dot states that describe the interaction of quantum dots with vacuum. It is shown that the variation of these self-energy functions can be significant and this can have a significant effect on processes of quantum interference from quantum dots

Tunneling-induced self-energy shift of energy levels of a quantum dot

© Published under licence by IOP Publishing Ltd. The self-interaction of a quantum dot tunnel with Coulomb interaction coupled to two noninteracting leads is investigated. The self-energy function describing this interaction is added to a bare energy of a dot state. In the standard way of determining the self-interaction (tunneling-induced) corrections to bare energies of emitters (atoms, quantum dots, etc) the variations of the self-energy functions with energy are ignored, and these corrections are considered to be equal to the values of the self-energy functions for bare energies of states. We show that actually in the case of quantum dots the variations of the self-energy functions in the energy interval between the bare and true energies can be strong, and this can have a significant effect on the values of the tunneling-induced shifts of energy levels of quantum dots

Influence of the photonic crystal medium on the self-interaction of electrons

© Published under licence by IOP Publishing Ltd. The self-interaction of an electron in the photonic crystal medium is investigated. We show that modification of the self-interaction of electrons in photonic crystals is very significant and, as a consequence, at some photon frequencies the electron-light interaction becomes effectively strong

Nanotechnology and global energy demand: challenges and prospects for a paradigm shift in the oil and gas industry.

The exploitation of new hydrocarbon discoveries in meeting the present global energy demand is a function of the availability and application of new technologies. The relevance of new technologies is borne out of the complex subsurface architecture and conditions of offshore petroleum plays. Conventional techniques, from drilling to production, for exploiting these discoveries may require adaption for such subsurface conditions as they fail under conditions of high pressure and high temperature. The oil and gas industry over the past decades has witnessed increased research into the use of nanotechnology with great promise for drilling operations, enhanced oil recovery, reservoir characterization, production, etc. The prospect for a paradigm shift towards the application of nanotechnology in the oil and gas industry is constrained by evolving challenges with its progression. This paper gave a review of developments from nano-research in the oil and gas industry, challenges and recommendations
