Ultraviolet photodissociation (UVPD) mass spectrometry is employed to investigate the structure of holo-myoglobin as well as its apo form transferred to the gas phase by native electrospray. UVPD provided insight into the stability of native structural elements of holo-myoglobin. The fragmentation yields from UVPD showed the greatest overall correlation with B-factors generated from the crystal...
Wojciech Grega Piotr Bania Department of Automatics, AGH University of Science and Technology, 30-059 Kraków, Al. Mickiewicza 30, Poland [email protected], [email protected] ABSTRACT This paper deals with a supervisory control strategy which enables to optimize heat energy distribution between buildings with discontinuous operation. The core principle of the energy saving algorithm is based on...
For convenience of outpatients, mammographies of outpatients are often taken after the injection of a radionuclide. In this study, we investigated the effects of gamma rays emitted by a patient onto imaging plates (IPs). We used a flat container filled with (99m)Tc solution as a planar source to irradiate gamma rays onto IPs. We changed irradiation times on each IP, and took radiographies of an...
assume ? ? l2(rd) has fourier transform continuous at the origin, with ˆ ?(0) = 1, and thatcan be represented by an affine series f = j>0 k?zd c j,k?j,k for some coefficients satisfying c 1(2) = j>0 k?zd |c j,k|2 1/2 <?. here ?j,k(x) = |deta j |1/2?(a jx ?k) and the dilation matrices a j expand, for example a j = 2j i. the result improves an observation by daubechies that t...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
Alpha-1- Protease inhibitor or a1-Antitrypsin (a1-AT) is an a1-glycoprotein and a small molecule which acts as an extracellular inhibitor of serin proteases. It seems that this molecule protein has a protective role in tissues such as inhibition (inactivation) of elastase, colagenase, etc. a1-AT deficiency is a hereditary disorder which characteristed by reduced a1-AT serum level and may ...
In this paper, we suggest the use of the chi-square test for detecting backoff misbehaviour in IEEE 802.11 EDCA networks. A performance evaluation is performed to compare the chi-square test with two other methods, known in the literature. To perform a suitable comparison, these two methods are extended to support EDCA and the BEB mechanism. We assume a misbehaviour model, which can be easily e...
Copper and silver, respectively, were introduced into single crystals of CsCdF3. Our detailed electron paramagnetic resonance (EPR) study showed that both elements enter the Cd lattice site-copper as Cu2+, silver as Ag+, which then was converted into AgH by x raying the corresponding samples. Cu2+ and Ai+ were shown to present in their ground state a pseudostatic J ahn-Teller effect. Motional e...
