In the present study, the influence of various solvents on UV-VIS absorption spectra of N,N-Bis(salicylidene)ethylenediamine (Salen) has been investigated. Salen ligand has two absorption maxima (around 260 and 320 nm). To explain the obtained spectra, the frequencies and molar absorptivity values were combined with solvent properties using a total solvatochromic equation suggested by the Kamlet and Taft. The multiparametric examination denotes that non-specific dipolar interactions of the solvents (π*) with the solute play a significant role in absorption maxima in pure solvents. The ionization constant (pK_a) of salen in methanol has been determined by spectrophotometric measurements. Two graphical methods have been applied

This research involves the study of permeability declination as a result of kaolinite due to the changing in pH in the Zubair reservoir (Lower Cretaceous) during the secondary production by water injection method. Four wells and six core samples within the North Rumaila field are studied, Minerals have been diagnosed by XRD and this specific site of clay minerals was diagnosed within the core samples by scanning electron microscopy (SEM). The core samples are also studied petrogrphically using the polarizing microscope and found that they mainly consist of quartz, while the predominant clay is kaolinite. The effect of pH on the values of permeability was examined through a series of laboratory experiments, as it has been tested in the ca

In the current research work a useful gap filling method was presented. Images over
Al Mosel city in Iraq were used as tested images. The linear algorithm for high
resolution (H.R.) image interpolation were based. The difference between the
proposed algorithm and conventional nearest neighbor algorithm is that the concept
applied, to estimate the missing pixel value, is guided by the nearest value rather
than the distance. In other words, the proposed concept selects one pixel, among
four directly surrounding the empty location, whose value is almost equal to the
value generated by the conventional bilinear interpolation algorithm. The
experimental results show that the proposed method demonstrated

The signal-to-noise ratio of the Charge Injection Device is considered the most critical factor for evaluating the quality of the Charge Injection Device (CID). CID produces unwanted signals (noise) that can obscure the signal that needs to be detected. Noise is an essential obstacle for spectral identification of the observed object because it generates a fluctuation that can surpass the signal level. Therefore, reducing noise is very important to get a high-quality image. There are three main types of noise in the CID camera system: shot noise, readout noise, and dark current noise. The readout noise has the highest impact on the astronomical image because this noise is caused by a variety of factors, including trapping-state noise, re
