Is Digitalization Improving Governance Quality? Correlating Analog and Digital Benchmarks
PublicationThe digitalization of public governance and the resulting concept of electronic governance is a characteristic feature of contemporary information society. Both can be defined as the process and outcome of digital transformation: transformation of the “analog” version of governance into “digital” governance. Measuring both versions of governance against typical performance measures of efficiency, effectiveness, equity, openness...

Amphotericin B and Its New Derivatives - Mode of Action
PublicationAmphotericin B (AmB) is a well known antifungal and antiprotozoal antibiotic used in the clinic for several decades. Clinicalapplications of AmB, however, are limited by its nephrotoxicity and many other acute side effects which are not acceptable by patientswhen their life is not threaten. In order to improve the therapeutic index of this drug, lipid formulations have been introduced and manyefforts have been made to obtain less...

Comparison of the coordination geometries of Zn(II) and Cd(II) ions in complexes with water, methanol and bulky aryloxysilanethiolate ligands
PublicationZinc and cadmium complexes containing silanethiolate anions and methanol or water were synthesized and characterized by X-ray diffraction, FT-IR and NMR spectroscopy, and DFT calculations. Contrary to zinc, the cadmium ion utilizes very weak donors to complete its coordination sphere; it forms contacts to phenyl rings of the silanethiolate ligand. Two zinc analogs of the general formula [Zn{SSi(OAr)3}2(L)2] where L = CH3OH (2)...

Tri(mesityloxy)silanethiol - The First Structurally CharacterizedOrganoxysilanethiol (Contributions to the Chemistry of Silicon-SulfurCompounds. 77 [1])
PublicationTri(mezytyloksy)silanotiol (TMST) wyizolowano jako jedyny produkt reakcji pomiędzy disiarczkiem krzemu a 2,4,6-trimetylofenolem. TMSTkrystalizuje w układzie trójskośnym. Dobra jakość kryształów pozwoliła na udokładnienie grupy SH bez narzuconych więzów. Długość wiązania S-H określono na 1,29(4) ang., a kąt Si-S-H na 95,4(17) deg. Cząsteczki TMST nie tworzą wiązań wodorowych w kryształach.

Projektowanie filtrów cyfrowych IIR o nietypowych charakterystykach przy użyciu algorytmu ewolucji różnicowej
PublicationW artykule przedstawiono zastosowanie algorytmu ewolucji różnicowej do projektowania filtrów cyfrowych o nietypowych charakterystykach amplitudowych. Przy użyciu proponowanej metody zaprojektowano trzy filtry o charakterystykach: liniowo narastającej, liniowo opadającej oraz nieliniowo narastającej. Opisane tą metodą filtry są stabilne a ich charakterystyki amplitudowe spełniają wszystkie założenia projektowe.

A Fast Method of Separation of the Noisy Background from the Head-Cross Section in the Sequence of MRI Scans
PublicationThe paper presents a new method of removing the noisy background from the sequence of magnetic resonance imaging (MRl) scans. The sequence of scans is required in order to monitor a passage of a contrast agent through the brain tissue. The scans contain the noisy head-cross data and also the noisy background data. The latter has to be removed and excluded from a further analysis. It is achieved by applying some basic morphological...

Enabling simultaneous redox transformation of toxic chromium(VI) and arsenic(III) in aqueous media—A review
PublicationSimultaneous conversion of most harmful As(III) and Cr(VI) to their less toxic counterparts is environmentally desirable and cost-effective. It has been confirmed that simultaneous oxidation of As(III) to As(V) and reduction of Cr(VI) to Cr(III) can occur via free radical or mediated electron transfer processes. While Cr(VI) is reduced by reacting with H•, eaq−, photoelectron directly or undergoing ligand exchange with H2O2 and...

Incorporating Iris, Fingerprint and Face Biometric for Fraud Prevention in e-Passports Using Fuzzy Vault
PublicationA unified frame work which provides a higher security level to e-passports is proposed. This framework integrates face, iris and fingerprint images. It involves three layers of security: the first layer maps a biometric image to another biometric image which is called biostego image. Three mapping schemes are proposed: the first scheme maps single biometric image to single biostego image, the second scheme maps dual biometric images...

Synthesis of 3-Carbamoyl b-Lactams via Manganese(III)-Promoted Cyclization of N-Alkenylmalonamides
PublicationManganese(III)-promoted cyclization of N-alkenylmalonamides (¼N-alkenylpropanediamides) gave 3-(aryl/(alkylamino)carbonyl) b-lactams as well as 3-(aryl/(alkylamino)thiocarbonyl) b-lactams. The relative configuration of the obtained products was unambiguously determined by X-ray crystallography. The proposed method is very useful for the one-pot synthesis of a number of 3-(aryl/ (alkylamino)carbonyl) b-lactams, especially those...
