in this study, functionalized β-cyclodextrin (β-cd) by aldehyde group was investigated as an oxidase enzyme mimic for the amino phenol oxidation. all calculations were performed by gaussian 09 package using two layers oniom method at the oniom (mpw1pw91/6-311++g(d,p)/uff) level. in the first step, h2o2 is encapsulated in the hydrophobic cavity. in the second step, h2o2 molecule oxidized the ald...
We further study the incidence relations that arise from the various subtowers, known as Baby Monsters, which exist within the R-Monster Tower. This allows us to complete the RV T class spelling rules. We also present a method of calculating the various Baby Monsters that appear within the Monster Tower. MSC Primary: 58A30 Secondary: 58A17, 58K50.
SN 2002kg is a type IIn supernova, detected in October 2002 in the nearby spiral galaxy NGC 2403. We show that the position of SN 2002kg agrees within the errors with the position of the LBV V37. Ground based and HST ACS images however show that V37 is still present after the SN 2002kg event. We compiled a lightcurve of V37 which underlines the variablity of the object, and shows that SN 2002kg...
We investigate the possibility to detect giant planets that are still embedded in young circumstellar disks. Based on models with different stellar, planetary, and disk masses, and different radial positions of the planet we analyze the resulting submillimeter appearance of these systems. We find that the influence of the planet on the spectral energy distribution could not be distinguished fro...
Background: Administrative violations of employees at their workplace create a conflict between individual and organizational goals. Due to the long process of handling these violations, this study aimed to identify and present some suitable solutions in order to reduce delay in the health sector. Materials and Methods: This study was carried out at three steps. At the first step, causes of...
background : in the recent decade, due to the overwhelming importance of health and prevention of diseases, nurses, having the most number of the health care team, are acting in any positions of the health care delivery system; because nursing have a key role in promotion of health and health care everywhere. the objective of this research was to study the desired positions of nursing in the he...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
The emergence of tiny computers, such as smart dust, Berkeley motes and Intel motes, makes it feasible to envision the conversion of a network of tiny computers into a regular computing device (i.e., a “PC” or personal computer). While the falling cost and increasing (yet tiny) computation power of these miniature computers portend well for this vision, there are significant technical hurdles. ...
