In this research, a low cost, portable, disposable, environment friendly and an easy to use lab-on-paper platform sensor was made. The sensor was constructed using a mixture of Rhodamine-6G and gold nanoparticles also Sodium chloride salt. Drop–casting method was utilized as a technique to make a platform which is a commercial office paper. A substrate was characterized using Field Emission Scanning Electron Microscope, Fourier transform infrared spectroscopy, UV-visible spectrophotometer and Raman Spectrometer. Rh-6G Raman signal was enhanced based on Surface Enhanced Raman Spectroscopy technique utilized gold nanoparticles. High Enhancement factor of Plasmonic commercial office paper reaches up to 0.9 x105 because of local surface plasmonic resonance. While for salty plasmonic commercial office paper, it grows up to 1.11 x 105. Particularly the unique properties of commercial office paper like low porosity, flexibility, portable, and high hydrophobicity are well suited for analysis of sample with arbitrary shapes and trace concentration as well as easily transferred to lab. From all the above, it is an excellent candidate for using as a lab-on-paper.
The current study aims to overcome the conflicts facing the company in its way of staying and continuing to maintain its performance excellent in light of the intense competition, which made it seek to find strong ways and links with its customers through electronic communication using electronic platforms, and this put confidence and safety in The place of suspicion and fear of not fulfilling credibility or violating the privacy, so this research comes to answer about the question: “Can the company achieve an excellent performance by relying on the customer's electronic confidence?”.
The study followed the descriptive and analytical approaches by providing a virtual model and testing the zero hypotheses, which stipulat

Show MoreThis paper concentrates on employing the -difference equations approach to prove another generating function, extended generating function, Rogers formula and Mehler’s formula for the polynomials , as well as thegenerating functions of Srivastava-Agarwal type. Furthermore, we establish links between the homogeneous -difference equations and transformation formulas.
2D Electrical Resistivity has been applied at three selecting areas within the study area using Dipole-dipole and Wenner arrays with an a-spacing of 1 m, and the profile length was 120 m for both. The total data points were 4455 reads for Dipole-dipole, and the total data points for Wenner were 2340 reads, and the depth of each array was 15.4 m and 20.2 m, respectively. The 2D inverse results indicate the resistivity anomalies approximately at depth (2 - 7.8) m formed as a weakness zone lies within the quaternary and Injana Formation deposits and interbedded with secondary gypsum and gypcretes. Additionally, the inverse resistivity distribution model demonstrated that the area is impacted by groundwater that is interaction wit

The Iraqi government identified 9 locations of informal settlement in Baghdad city and acceptance it as a reality as a help for them to getting home. In this paper I discovered the suitability of those locations which one will be suitable more than others for living. The analysis process was applied using the GIS environment – spatial analysis. According to the results, It has been identified as the most important measures to identify which one of these areas suitable for development for housing by using some criteria (Distance from the city center, Proximity from transport routes, Proximity of high v
... Show MoreDensity Functional Theory (DFT) at the B3LYP/ 6-311G basis set level and
semiemperical methods (PM3, AM1, and MINDO/3) were performed on six new
substituted Schiff bases derivatives of INHC (N-(3-(phenylidene-allylidene)
isonicotinohydrazide) using Gaussian-03 program. The calculated quantum chemical
parameters correlated to the inhibition efficiency were studied and discussed at their
equilibrium geometry and their correct symmetry (Cs). Comparisons of the order of
inhibition efficiency of the Schiff bases derivatives, and local electrophilic and
nucleophilic reactivity have analyzed. Some physical properties also were studied
such as heat of formation, total energy and dipole moment...etc. Also vibration

Abstract:
The problem of the research is that the person face in the starting of his
profession life is to go to the right profession that he or she fits in when the
person enter the works sea many problems appear to him on of them is his
non-accordance with his job ,the research targeted to know the levels of the
accordance of the kindergarten teachers and the relation between the
profession accordance and other like the kind of level and the time of service
and the research worked with (150) kindergarten teachers from the
introductory class and (150) kindergarten teachers from the kindergarten class
for the study year 2008-2009 .
The research been made a measure to get the goal of the research after
