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...

This paper analyzes an induction motor with high temperature superconducter (HTS) coated slotted solid rotor. By slotting the solid rotor, the electromagnetic torque near synchronous speed will increase but the starting torque will decrease. To improve starting torque, rotor slots are coated with HTS materials. Using HTS material vary the rotor resistance to great extends in starting step and t...

This paper describes a new class of anti-stiction coatings for silicon MEMS that is based on the free radical reaction of a primary alkene (e.g., 1-octadecene, C16H33CH=CH2) with hydrogen terminated silicon [1,2]. The new monolayer coating has several key advantages over the previously reported octadecyltrichlorosilane (OTS) and 1H,1H,2H,2Hperfluorodecyltrichlorosilane (FDTS) based self-assembl...

Abstracts Micro-arc oxidation (MAO) coatings were prepared on the AZ31 Mg alloy under constant/gradient current control modes. The effects of output modes growth rate, energy consumption, microstructure, and corrosion resistance MAO studied. results shows that step-down mode (G852) exhibited a lower unit consumption than constant (C5) step-up (G258), even though same average density was used du...

PURPOSE Magnetic submicron particles (MSPs) are pivotal biomaterials for magnetic separations in bioanalyses, but their preparation remains a technical challenge. In this report, a facile one-step coating approach to MSPs suitable for magnetic separations was investigated. METHODS Polyethylene glycol) (PEG) was derived into PEG-bis-(maleic monoester) and maleic monoester-PEG-succinic monoeste...

A simple one-step method based on the sputtering deposition of Ni nanoparticles (NP) has been developed for the production of magnetic biocatalysts, avoiding the complications and drawbacks of methods based on chemical functionalisation or coating of magnetic NP. This new technique provided high levels of recovery, reusability and catalytic activity for the lipase-Ni biocatalyst.
