In multi-elemental compound-specific isotope analysis the lambda (?) value expresses shift of one element versus a second element. dual-isotope plots, slope regression lines typical reveals footprint underlying effects allowing to distinguish degradation pathways an organic contaminant molecule in environment. While different conventions and fitting procedures are used literature determine ?, i...

Background: Biometrics Authentication is the process of measuring biological, physical and behavioural characteristics to identify verify individual. Most are inherited cannot be guessed or stolen. Objectives Aims: The present research aims investigate a novel method in Biometric authentication overcome difficulties that exist Authentication. study trace elements biological nail tissue their co...

alumina-supported cs3[re(c2o4)3] precursor has been synthesized  for preparation of re-cs/g-al2o3 catalyst. cs3[re(c2o4)3]  has been prepared from the reaction of recl3 with  h2c2o4.2h2o and cscl in water. the complex has been characterized by elemental analysis and various spectroscopy techniques such as ft-ir, uv-vis and 13c-nmr. the complex was supported on γ-al2o3 by column chromatography. ...

a new sorbent composed of 3-aminopropyltriethoxy-silane-coated magnetic nanoparticles, functionalized with rhodium(iii) porphyrin complex was synthesized and characterized by elemental analysis, x-ray diffraction (xrd), transmission electron microscopy (tem), fourier transform infrared spectroscopy (ft-ir) and thermogravimetric analysis (tga). the effect of some co-existing anions present in aq...

AIM To investigate using finite element stress analysis (FEA) primary, secondary and tertiary monoblocks created either by adhesive resin sealers or by different adhesive posts and to evaluate the effect of interfaces on stress distribution in incisor models. METHODOLOGY Seven maxillary incisor FEA models representing different monoblocks using several materials were created as follows: (a) p...
