The copolyimides were characterized by Infra-red (IR), Nuclear Magnetic Resonance (NMR), Gel Permeation Chromatography (GPC), Ultraviolet Visual (UV-Vis), Thermogravimetic Analysis (TGA) and Dynamic Mechanical Analysis (DMA).
      
The surface composition of the blend films was determined by Fourier transform infra-red spectroscopy coupled with a variable incidence angle attenuated total reflection accessory (ATR-FTIR).
      
This paper is devoted to analyzing the basic results of nadir observations of the infra-red SPICAM channel during the first Martian year of the instrument operation: from January 2004 to November 2005.
      
Theδ-equivalence classes of the identity map, the Y-diffeomorphisms of infra-nullmanifolds, and the connection betweenδ-equivalence and topological entropy are studied.
      
CO2 exchange was measured with a Li-Cor 6400 infra-red gas analyzer in attached leaves placed in a climatic chamber in the morning under growth conditions and saturating light 1200 μE/(m2 s) in June, July, and August.
      
Dielectric properties of single-crystal deuterated triglycine sulfate (DTGS) in ultra-weak low-and infra-low-frequency electric
      
The granite-greenstone terranes exposed and overlapped by sedimentary cover are identical, although they generally differ in internal structure and rock compositions both at the infra-and supracrustal levels.
      
Primary intracranial extradural hydatid cyst localized in the supra-and infra-tentorium
      
After chemical evaluation, the obtained pulps were classified using Fourier Transformed Infra-Red Spectroscopy and Principal Component Analysis.
      
Compared to supratentorial ischemic lesions, patients with HI-infra presented with a significant higher disturbance of consciousness (assessed with the Glasgow Coma Scale) and severity of the disease (assessed with the APACHE II Scale).
      
It is not abolished either by a homolateral retrogasserian neurotomy with preservation of the trigeminal motor root or by local anaesthesia of the homolateral infra-orbital and mental nerves.
      
Close correlation between the degree of infra- and supratentorial atrophy was found only in chronic alcoholics.
      
Infra-red (IR) data verify the copolymerization between PU and TFPA.
      
The extracts were then analysed by infra-red (IR) spectrometer to measure the maximum absorption of the C-H stretch of CH2-CH3 band at wavelength of 2 930 cm-1.
      
This article reviews the combined technique in which vapors eluted from gas chromatographic columns are identified by their infra-red spectra.
      
A new method, based on the combination of four techniques (gas chromatography, infra-red and ultra-violet spectrophotometry, thin-layer chromatography), is applied to the determination of aromatic amines in rubber vulcanisates.
      
The chromatography of wax components using infra-red detection coupled with gradient elution has been studied.
      
The indices are calculated from infra-red shifts of 1-chlorobutane and the visible wavelength shifts of l2 when they are dissolved in the stationary phases, from NMR estimates of acidity and basicity and from relative retention data.
      
Combined gas chromatography-infra-red spectroscopy for the determination of propanediol in acyclovir cream
      
Analysis of a solvent extract by gas chromatography coupled to an infra-red spectrometer enables the target analyte to be positively identified and an estimate of its concentration to be made.
