Photolysis of Steroidal 20-Aryl-Substituted 11-Nitrites
(Wiley, 1997)
The two structurally similar 20‐phenyl‐ and 20‐(4‐methoxyphenyl)‐11‐(nitrosooxy)pregnan‐20‐ol derivatives 4 and 7 behave differently under photolytic conditions, the former nitrous acid ester affording, as a main product, ...
A method for spectrophotometric determination of acetaldehyde with thiosemicarbazide in blood / Spektrofotometrijsko određivanje acetaldehida u krvi sa tiosemikarbazidom
(Niš, Serbia : University of Niš, 1998)
The thiosemicarbazide method for spectrophotometric determination of acetaldehyde (AcH) in whole blood is presented. The concentration of thiosemicarbazone formed in slightly acidic ...
Regulation of cell processes by rective oxygen and nitric oxide species - Mechanisms of reactions / Regulacija ćelijskih procesa reaktivnim vrstama kiseonika i azot monoksida - Mehanizmi reakcija
(Yugoslav Union of Physiological Societies, 1998)
Recent evidence revealed that reactive oxygen species (ROS) such assuperoxide (O ) and hydrogen peroxide (H O ), which are conventionally2.-22viewed as unwanted and toxic by-products of life in an aerobic environment,have ...
Photoacoustic investigation of thermal and transport properties of amorphous GeSe thin films
(AIP Publishing, 1994)
In this work the possibility of simultaneous determination of thermal and transport properties of thin films using a photoacoustic method was investigated. The properties of amorphous GeSe thin films, which were evaporated ...
Optical properties of guanidinium aluminium sulphate hexahydrate (GASH)
(IOP Publishing, 1993)
Far-infrared reflection spectra were determined, for the first time, for single crystals of guanidinium aluminium sulphate hexahydrate (GASH) and its solid solution for 5 mol.% chromium isomorph (GCSH). The infrared active ...
The ωσ method: A new contactless comparison method for measuring electrical conductivity of nonferromagnetic conductors
(AIP Publishing, 1997)
A novel, very simple, eddy current method for measuring the electrical conductivity of nonferromagnetic conductors is described. This method is relative, i.e., we measure the ratio of conductivities of two samples of the ...
Photoacoustic frequency heat‐transmission technique: Thermal and carrier transport parameters measurements in silicon
(AIP Publishing, 1995)
Photoacoustic frequency heat‐transmission technique is used to study thermal and carrier transport properties in low‐doped silicon wafers. Amplitude and phase photoacoustic signals as a function of modulation frequency of ...
Planar Thick Film Integrated LCV Cells
(Emerald Group Publishing Limited, 1995)
New thick film devices were developed to integrate thick film planar inductors L, capacitors C and varistors V into single hybrid devices called thick film planar LCV cells. The first thick film planar LCV cells were printed ...
Exposure of Mn and FeSODs, but not Cu/ZnSOD, to NO leads to nitrosonium and nitroxyl ions generation which cause enzyme modification and inactivation: an in vitro study
(Elsevier, 1999)
The effect of NO treatment in vitro on structural and functional alterations of Cu/Zn, Mn, and Fe type of
SODs was studied. Significant difference in response to NO of Cu/ZnSOD compared to the Mn and Fe types was
demonstrated. ...
Far infrared properties of PLZT ceramics
(Springer, 1997)
Far infrared and mid-infrared reflectivity measurements have been made of lead titanate zirconate (PLZT) ceramics at room temperature in the frequency range 40–1500 cm-1. Kramers-Krönig analysis and a fitting procedure ...
