The research dealt with an important and critical era in the history of the Seljuk State of the Romans in Asia Minor, as that country, after the assumption of Sultan Ghiath al-Din Kehsaru II in the year 634 AH / 1236 CE, was subjected to the constant Mongol threat, so the research came marked with (the Seljuk State of Rome in Asia Minor and the Mongol invasion 634 - 708 AH / 1236 - 1308 AD) The research showed the succession of the Seljuk Sultans to the rulers whose rule after the death of Sultan Alaeddin Kikbad was weak and subject to the authority of the Mongols and the conflict of the sons among them over the throne of the Seljuk Sultanate, and to clarify the dispute that occurred between Izz al-Din Kikaus and his brother Rukn al-Din Qulayj Arslan Izz al-Din took refuge in Constantine The discussion dealt with the understanding and alliance between the Turks of Asia Minor and the Mamluk sultans in Cairo with the intention of confronting the common Mongol enemy. The relations of that country with the Abbasid Caliphate and the neighboring countries of the Khwarizmites and the Ayyubids were discussed.
The research dealt with the Mongol threat to the Sultans of the Seljuk state, as their country visited the Tatar forces and fought with them important battles, the most famous of which was the Battle of Kusa Dag
That ended with the victory of the Mongol forces over the Seljuks of the Romans in the year 640 AH / 1242 CE.
The research touched on the end of that country after the death of their last sultans Sultan Masud bin Izz al-Din Kikaus Masoud II, so the rule of the Seljuks in Asia Minor ended, which resulted in the emergence of a large number of Turkish Emirates on the ruins of the Sultanate of Rum in the year 708 AH / 1308 CE.
Several types of laser are used in experimental works in order to study the effects of laser on blood vessel. They differ from each other by a lot of properties mainly in wavelength, energy of the laser and pulse duration. In this study argon laser (488 nm- 514 nm) and continuous Nd: YAG laSer (1064 nm), have been applied to 50 samples of sheep blgod tesselS. Histologically, tha results of the study were different According to the txpe of L`sar used; apgon larer had distrabtave effects on $he blood vessal while continuous Nd: YAG laser Appeaped to be the safesd one on the blmod vessel architecture.

The presence of gypsum in soil as bonding agent alters its behavior with a large influence on itsphysical properties.Soil samples were taken from two locations of different gypsum content(S1 = 30.5% and S2= 20%) inMakhmur area. TheUnified soil classification system indicated that soil type was clay with low plasticity(CL). Basic methods of physical testing of soils, such as grain size analysis,specific gravity and atterberg limit were applied. Stabilizationof the gypsiferous soil was performed by addinglimestone waste powder takenfrom Said sadiqandPirmam areas,with different percentages(5%, 15%,25%).The results show that the addition of limestone powder to the tested soils decreases their liquid and plastic limits.

Separation of Trigonelline, the major alkaloid in fenugreek seeds, is difficult because the extract of these seeds usually contains Trigonelline, choline, mucilage, and steroidal saponins, in addition to some other substances. This study amis to isolate the quaternary ammonium alkaloid (Trigonelline) and choline from fenugreek seeds (Trigonella-foenum graecum L.) which have similar physiochemical properties by modifying of the classical method. Seeds were defatted and then extracted with methanol. The presence of alkaloids was detected by using Mayer's and Dragendorff's reagents. In this work, trigonilline was isolated with traces of choline by subsequent processes of purification using analytical and preparative TLC techniques.

Nine stations were chosen located on Tigris River, Tigris-Therthar channel, Groundwater, and Therthar lake. The results indicated that the TDS increased in summer season, and the effect of Tigris-Therthar cannel was limited, also the effect of groundwater was limited, but there was an indication refers of possibility of increasing these effects on the quality of water. The study recommends observing the Tigris River through a programme to identify any change in water in future.
This study was conducted to evaluate the efficacy of different techniques for extraction and purification of Tomato yellow leaf curl virus (TYLCV). An isolate of the virus free of possible contamination with other viruses infecting the same host and transmitted by the same vector Bemisia tabaci Genn. was obtained. This was realized by indicator plants and incubation period in the vector. Results obtained revealed that the virus infect Nicotiana glutinosa without visible symptoms, while Nicotiana tabaccum var. White Burley was not susceptible to the virus. The incubation period of the virus in the vector was found to be 21 hrs. These results indicate that the virus is TYLCV. Results showed that Butanol was more effective in clarification the

This study is designed to evaluate the immune status of patients and schoolchildren with respect to Streptococcus pyogenes. A prospective study was conducted to investigate antibody against GAS in children patients and asymptomatic healthy carriers in serum samples with tonsillitis and compare antibody response (ASO) between patients and healthy carriers with tonsillitis.
Tonsillar swabs were obtained to detect the presence of GAS and blood samples were collected to determine elevated ASO titer in serum.
A total of 376 sample patients and asymptomatic healthy carriers were included in this study, 142 (37.7%) samples are GABHS positive, included 80 (56.3%) patients and 62 (43.6%) asymptomatic healthy carriers. The finding of a signi
The Islamic Bank of Al-Nahrain offers a formula for financing the purchase of real estate through a deferred sale contract, through Murabaha to the order to buy, and the payment of the price is in the form of instalments that include (the purchase price of the profit and the mutual agreement on the real estate). This research aims to show the reflection of real estate murabaha on the bank's investments, by measuring the effect of real estate murabaha on the profits achieved by the Islamic Bank of Al-Nahrain Bank. The growth of 'real estate murabaha' realized from the 'amounts granted by Bank X, in addition to analyzing the financial ratios of profitability indicators, including (return on deposits Y2) and for the years (2016 - 20
