In this work, the effect of sunspots number (Ri) on the Total electronic content (TEC) were studied for the years (2008, 2014, 2018) which represents the rising phase, the peak and the down phase of the solar cycle 24 over Kirkuk station in Iraq at latitude 35° North and longitude 44° East, by finding the TEC values for the E – layer, the layer’s impression times are determined for the days of solstice and equinox. In this study the International Reference Ionosphere program (IRI) program have been applied to find the values of TEC which provided by the space research committee (COSPAR) and International Union of Radio Sciences (URSI), IRI have three upper side electron density options. The accuracy of this study was verified by the application conducted of the university of Hacettepe in Ankara, Turkey by matching the reading of TEC from Global Position System (GPS) with output data of TEC from the IRI for Ankara station which located at (39.7 N;32.76 E). And from this investigation turns out that the output data from the option IRI2001 was more consistent with reading of the GPS, than the rest of the other options. From this study by using the statistical program Minitab version 2018. There is a strong correlation between the Total Electron Content (TEC) of Ionospheric layer E and Sunspot number for solar cycle 24.

The massive use of the internet in our contemporary life relates to the increase of the exchange of information through the Internet networks. Due to the importance of the information and to preserve its confidentiality, it protects using theories as well as strategies from attack or abuse. The aim of the research is to design an algorithm to encrypt text symbols to understandable symbols using private table that contains representation of ASCII of English characters with their suitable Sumerian system numbers. Each letter of the text is converted to ASCII code then encoded as an image using the private table, After that these images are combined together and saved as a new image as a Sumerian image. This image is encrypted first with unintelligible key image that is generated from three external key’s (kr, kg, and kb) to be the first stage encryption image. Then the second stage image generates from encrypting the first stage image with another input key image using XOR function which increases image security. The proposed algorithm gives double stage encryption and high degree of security level because of using Sumerian system and using different keys and security methods. Through using the histograms on all tested images, the result image demonstrate the efficiency of the system visually.

The present study aims to assess the pollution of groundwater with toxic heavy elements and their carcinogenic and non-carcinogenic effects on health in the study area. For this purpose, 5 samples of groundwater wells were taken and analyzed for their content of the elements (Pb, As, Cr) using the ICP-MS device in the ACME laboratory in Vancouver / Canada. The results of these five wells showed that their concentrations rates increased according to the following order Pb> Cr> As, as they reached 45.34, 11.8, and 0.74 µg l-1, respectively, and the lead, arsenic and chromium levels in the five samples were within the permitted ranges according to FAO standards, the spatial distribution of the three elements showed that the lead concentration in groundwater was high in the eastern regions, which may be due to the impact of vehicle emissions and agricultural activities, while arsenic and chromium concentrations were high in the central and southwestern regions of the study area, which may be attributed to the effects of agricultural and industrial activities. And it was found by applying the indicators of heavy elements pollution (MI, HPI) and health risk factors that the five wells under study are not contaminated to low pollution with these elements respectively, and do not pose any carcinogenic and non-carcinogenic health risks to the population of the study area of adults and children through skin contact pathway.

Ghaadh. T. Abdulla

Kirkuk University Journal-Scientific Studies, 2007, Volume 2, Issue 3, Pages 52-66

Eight varieties of durum wheat (Leeds, Waha, Um Rabie5, Azegar1, Um Rabie3, Brashua, Cyprus1 and Korfila) and their half diallel crosses were used in this study to construct several selection indices and calculate the gains expected in the yield. It was revealed that the selection index constructed from plant yield, number of spikes plant, number of tillers and harvest index had the highest increase in the efficiency (5.75%) as compared with direct selection for yield. This indicate that a selection index based on combination of characters, including yield, would have an advantage of practical significance over selection based on yield only. This index considered the superior due to it’s high efficiency and constructed of lowest number of characters. By the estimation of the eight varieties selection index values, it was found that Um Rabie5 had the best value, then Um Rabie3 and Azegar1 consequently.

A New Technique to Compute Complex Roots

Sasan A. Muheadden

Kirkuk University Journal-Scientific Studies, 2010, Volume 5, Issue 1, Pages 104-113

In this paper we modified Newton – Raphson and Secant methods to Complex form, then from that we get new iterative formula to them, named Newton (Secant) real iteration formula and Newton (Secant) imaginary iteration formula, real iteration used to find real roots while imaginary iteration one will be used to find complex roots of non- linear equations such as ( ). To find real roots, we start with a real initial point in real iteration getting a sequence of real numbers, to find complex roots start with a complex initial point in complex formula getting a sequence of complex numbers, also we write a new algorithm for this technique and write the program by using Matlab application system version 7.8 for this new method such that it will determine the real roots when we enter the initial real point but when we enter the initial complex point it will determine the complex roots.
