المستخلص: Al - Massiehly Site is one of the areas located in the district of Shirqat in Salahuddin province, which witnessed charismatic human activity over the history. It also has its importance in Mesopotamia rich history of diverse civilizations and achievements in various fields. Such achievements had their impacts on other contemporary ancient civilizations which existed beside Mesopotamia successive triumph civilizations. One of the most important of such achievements was the invention of pottery, which had a significant impact on the agricultural life and its fruitful outcomes in Mesopotamia.The significance of the invention of pottery production lied in its great influence on social, economic, commercial, religious and artistic life due to the role it played in fulfilling a vital need for a material that is applicable to many essential areas from basic needs of household uses such as keeping liquids or cooking food, to storing some grains such as barley and wheat which have always been associated not only with village and farmers' life; but even with vibrant urban life close to the farming .From there emerged its economic and commercial significance after the emergence of important institutions such as the temple with its high profile position in terms of religious, economic and political importance, which had had a great influence on the hearts of the sons of Mesopotamia. Moreover, pottery pots had their significant impact on religious practices which, in turn, influenced the community customs and traditions as well as the after death rituals, as many of those pots were buried with the dead; in what is nowadays known as the "Funerary Gifts".Pottery was not totally devoted to domestic use as a means of storage or a bowl for drinking, but it also was a masterpiece which has communicated through the ages the message of civilization and the great diversity in areas of thought and artistic creativity, through what those pots carry of decorative methods variety, whether that was geometrical or natural decorations symbolized by geometrical or botanical shapes or by some abstract shapes of human and animal anthropomorphism. These arts are considered as messages which served us well in the know about of the life of ancient people of Mesopotamia, whether in social, economic or technical aspects.Pottery also forms an important link, if not the most important of all, for researchers, through which they could trace the chronology of the roles of civilizations incubated by this historical site, particularly those dating back to the prehistoric times, where a pottery fragment is considered to be the best guide to the habitats of history and the key to many question marks and exclamation points. The aim of studying this type of pottery, which dates back to prehistoric times, is to shed light on the status of this site and the amount and importance of what has been obtained from it of archaeological findings belonging to Al - Ubaid period, as the focus of the study will be such historic monuments from archaeological and technical/ artistic angle as well as the expansion this era had witnessed which included the entire of Mesopotamia and neighbouring countries. Pottery pots, in general, had such technical characteristics and artistic features which were unique to Al - Ubaid period, but were superficially addressed by many researchers while they are worthy better highlighting in a wider scope study, as they were found in several archaeological sites in and out of Mesopotamia, and many archaeological excavations have been dug out which date back to the Al - Ubaid period . Our study of the heritage of this Era has been based on archaeological excavations records as well as reviewing of local researches and studies published in the Journal of Sumer and Arabic studies including the Syrian Arab Archaeological Annual books, in addition to other important references including the study of professor Dr. Taqi Al - Dabbagh on old pottery, and on the foreign sources and references represented by foreign excavations reports at some sites in Mesopotamia, including excavations of the French mission at the site Al - Owaili, as well as the (Iraq) magazine which dealt with some specific aspects of this period . Such sources and references were an excellent guide and a reliable assistance in the opinion confirmation on the subject.In order to focus on one specific aspect of the many aspects of this study, and due to the multiplicity and diversity of the archaeological excavations findings in many sites in Mesopotamia and beyond, it must be stressed that the Al - Ubaid period is one of the important ages which had inherited from its predecessors and left us, the successors, a wealth of culture of impact both at home and abroad. Study the Pottery of this period has not attained a great deal of interest or extensive studying research, taking into consideration its term of time which stretched over nearly the period of (4500 - 3800 B. C), as well as the wide geographic spread it had witnessed in Mesopotamia and neighbouring countries, with the exception of the few studies which have been mostly in foreign languages. It has, therefore, been proven necessary to pursuit research and investigation in order to access those documents in obviously tough circumstances as the country, as a whole, and the research area (Sharqat), in particular, are witnessing serious security deterioration where we faced a lot of difficulties in achieving our aspirations, including scarcity of resources and the difficulty of obtaining missions excavation report. The objective of our study is to investigate the Al - Ubaid period pottery through what had been found at the archaeological site of Al - Massiehly, in addition to conducting a comparative study between the findings of Al - Ubaid period pottery found at the site of Al - Massiehly with similar findings found in other sites of Mesopotamia including industrial techniques analysis and the forms and methods of executing decorations on the hulls of those pots.Our study on this subject was not limited to the archaeological findings alone, but we also took samples of those models in order to conduct laboratory tests and analyses on them to identify their chemical components and the materials they contain, as well as those used in their colouring and decorations.....This study had included four chapters : hapter One : titled "The Geological Formation and Geographical Environment of the Al - Massiehly site"; and has included three sections : First section : Al - Massiehly, The location, the naming, Archaeological Excavations; Second section : The Geographical Environment of the Al - Massiehly site;Third section : The Region's Natural Resources. Chapter Two : titled "Al - Ubaid Pottery : The naming - Its Technology and Styles in light of published sources; this Chapter has included two sections : First section : Al - Ubaid Pottery : The naming - Its Technology;Second section : Styles of the Al - Ubaid Pottery;Chapter Three : titled "An applied comparative study of the Al - Ubaid Pottery from the Al - Massiehly site with other sites of Mesopotamia; and the Chapter has been divided into three sections : First section : Simple Pottery (The Technology, Shapes and the Usage) Second section : Coloured Pottery (The Technology, Shapes, Decorative Patterns and the Usage)Third section : Incised Pottery (The Technology, Shapes, Decorative Patterns and the Usage)Chapter Four : It was titled "Geographical Spread of Al - Ubaid Era Pottery in Light of Archaeological Excavations and Surveys"; and has included two sections : First section : The Geographical Spread of Al - Ubaid Era Pottery in Light of Archaeological Excavations and Surveys in Mesopotamia Second section : The Geographical Spread of Al - Ubaid Era Pottery in Light of Archaeological Excavations and Surveys outside of Mesopotamia Finally, it suffices me that I have been able to shed light on this important site from prehistoric times, namely Al - Massiehly site. Should I have been successful, that would be my ultimate wish, but if mistaken, though, it would be an error of an industrious attempt, as if there was any perfection; it would have to be the Almighty God's alone

المستخلص: The third dynast of Ur is considered to be the period of the last Sumerian political and military Renaissance. This dynast has imposed its political and military authority all over Mesopotamia as well as outside it towards the north and east. As far as other aspects, such as cultural and economical aspects, the Sumerian influence was so huge on this period of the third dynasty of Ur, the matter which represented the total sum of the Sumerian knowledge and cultural influence that dominated Mesopotamia and its neighboring countries during this period and the following periods as well. What is noteworthy is the fact that most of the texts resulted from this period are economical texts which have great importance to be studied so as to conclude the type of the economical system that was dominate that period concerning exchanged materials were used by the people of that time and which, weighs, measures, numbers, spaces were used and with what materials. Moreover, these texts have a considerable value in studying the personal names of that period mentioned in the texts to enable researchers to realize different populations and races that used to occupy this area and to see whether they were the native people of this country or they were no more than (foreigners). This type of knowledge would guide researchers to know to which city any personal names exactly belong through elaborate comparisons with other studies and researches that dealt with this subject. On the other hand, there is still another importance to economical texts which can be witnessed in studying the names of months that are typically related to agricultural activities in order to notice the differences in the arrangement of these months among multiple cities. Lastly, these texts and through the study of date formula will enrich the historical information related to the period of every king and the different incidents events in his own reign. Thus, this dissertation tackles fifty four economical confiscated texts that belong to different cities and gathered from certain collections found in the Iraqi Museum which I've faced great difficulty in reading some of them. Such difficulty is attributed to the smash or erasing of these sign out of direct contacts, the matter which greatly affected the clarity of the numbers printed on these texts. The study fall into five chapters the first chapter of the study represents the central chapter which contains the reading of texts, translating them and presenting the general contents of these texts along with their analysis. Chapter two consists of a study of the personal names mentioned in these texts in addition to an analysis it. With specifying the place to which each name written on the tablet belongs to compare it with names from other cities. Chapter three includes two sections. The first section is devoted to study the date formula, whereas section two is tackling the study of the month’s names due to their belonging in different cities. In addition to that, this section contains an arrangement of the months in a list which would help after all to identify each text to its belonging place. Chapter four also consists of two sections. The first section deals with the study of the names of cities and geographical sites mentioned in the named texts so as to identify the geographical map for these texts. Section two, on the other hand, includes the types of professions and manual works illustrated in these texts. Finally, the chapter includes a conclusion that sums up the major findings of the study. Chapter five contains lists and schedules of these texts, followed by copies of the cuneiform tablets, a bibliography of Arabic and foreign sources and an abstract in English.

المستخلص: It is obvious that every fair - minded that the study of ancient Iraqi languages, especially the Akkadian language and reading the cuneiform texts, which was recorded in this language, is of a great importance to identifying the ancient history of Iraq and the civilization achievements which made in this important part of the ancient world. Even become the cuneiform texts, the main source on which depend on most of researchers in interpreting of the political developments and cultural achievements which was Mesopotamia gripped during the Sumerian, Akkadian, Babylonian and Assyrian periods. There are some reasons behind the choice the title of this study "The Request Style in the Akkadian language A comparative study with the Hebrew language" : the first one, being that is one of most important and essential subjects, and that the topic was a new and has not been tackled in a rhetorical depth, especially by the academic researchers, foreign as well as Arabs. The request style have gains a large area of Akkadian language, and almost no cuneiform text empty from these styles, as well as this study was comes to find out some of the eloquence secrets in both Akkadian and Hebrew through experience the text to learn these styles and determine their exact meanings, especially since the request style construction is one of the most important sections of semantics involves beneath connotations and hidden meanings, not aware, without diligent and patient attitude. The Akkadian library - so to speak - is almost empty - handed from the books which is talk about the Akkadian rhetoric, especially in this (meanings) , and if we found anything of that thy would be of general nature and views,and thy would be duplicate observations in most cases, this situation applies to the Hebrew language. So that this study is the first one which "knock on the door" to talk about these styles The past methodology of the study in the college was tackled the comparison between the Akkadian and Arabic in particular,and with others Arabite languages in general, while this study depends upon the Hebrew language as model for comparison with the Akkadian language. The Hebrew language represents one of the most important Arabite languages which is spoken at this time, and the study of the Hebrew language in the department of Cuneiform Studies had a major role in choosing this topic, because this approach helps the students taste the Akkadian language when compared with other Arabite languages to and shows the similarities and differences on the light of the applied and descriptive approach to study the grammar and rhetoric phenomena . Hebrew language is the language spoken by the sons of Israel, its a branch of the large linguistic family called Arabite languages, Hebrew language was not in itself, but it was composed of several dialects of Canaan, where grew up primarily on the land of Canaan before the exodus of the sons of Israel to it. The study depends upon the ancient Babylonian dialect ( -  BC),as a basis. As for the Hebrew language, we have adopted the grammar of ancient Hebrew, this stage begins about the tenth century (B.C) about ( -  BC). The approach which is taken by the study is the analytical method, which is based on the study of the characteristics and features of the request styles which came from the nature of the Akkadian and Hebrew texts, , because its approach questioning the connotations through the syntax of the texts, these texts are addressed to reveal the ingredients of these styles and its meanings There is one issue which is worth mentioning, namely the role of the Arabic language in the enrichment of the topic for the rhetoric article, especially in the area of the metaphorical meanings, as the Akkadian language lacks from the rhetorical studies and secondary meanings. This study is divided into four chapters. There is an introductions brief revealing the value of these styles in the speech. The first chapter tackled "The command style" in both Akkadian and Hebrew contrasting and applications, and the research is addressing to statement the formats of the command style, its definition and formulation, drained and derived from the triple and quadruple forms, and showing of its meaning and its connotations nearby clear and the long - hidden, or what is called the first meanings and second one, were applicable in this study on a number of Akkadian and Hebrew texts, which came to those styles. The second chapter is devoted to "The prohibition style", and its tools and applications in Akkadian and Hebrew, as well as rhetorical meanings that came to it, and as the pattern of the first chapter. Chapter three examines "The interrogative style" and the ways of fulfilling its the functions as the interrogative by tools, characters, tonal, and verbs, and statement its metaphors meanings that came out to it. Followed by the fourth chapter, which is including three styles, the first is involved on study "The wishful thinking styles" and tools, and meanings, followed by the second style, which examined "The Vocative style" the study explains its tools and its uses, and then third style deals with identify of "The demand style by the announcement format" These chapters varied in their material subject, and that was inevitable, because the nature of the subject mater of these styles, and multiple forms of each and breadth of the meanings of others. Finally, the conclusions of the research included the main ideas and results.

المستخلص: One of the main linguistic characters in ancient Iraq is what is known "Sumero - Akkadian Bilingualism". In spite of the importance of the subject, little has been written about it mostly in foreign languages. This fact had lead us to choose the subject for our Ph.D. research.Bilingualism in ancient Iraq goes back to the fourth millennium B.C. since Sumerians and those who spoke Akkadian lived in the southern part of Iraq since that time. Bilingualism phenomena has lead to several linguistic results first of which was the mutual linguistic effects of Sumerian and Akkadian languages. Then the invention of what we call the Sumerian and Akkadian lexicons in addition, the writing of certain texts in both Sumerian and Akkadian languages, i.e. the bilingual texts.The thesis was divided into four chapters, the first gives a linguistic background in ancient Iraq, while the second dealt with Sumero - Akkadian bilingualism. The third chapter is concerned with the mutual effects of Sumerian and Akkadian languages. In the last chapter the main results of Sumero - Akkadian bilingualism, that is the Sumerian - Akkadian lexicons and the bilingual cuneiform texts were dealt with

Effect the rotation speed of mold casting and overheating temperature on the microstructure and hardness of ahypereutectic ( Al - 23%Si) alloy were investigated. Therefore, the melt was overheated to( 800,900) C? and poured in the centrifugal casting mold after preheating by used gaseous torch to (100) C?. Then we obtained on cylinders at different rotation speed (765,840,1043,1712,1878) r.p.m. Optical microscopy and scanning electron microscopy used to study the microstructure to produce samples. The results showed that the overheating temperature and mold rotation speed affect on the grain size and volume fraction of ( ? - Si) phase, increasing of the overheating temperature due to increasing average volume fraction and decreased the grain size of primary silicon, but increasing mold rotation speed due to increasing the average volume fraction in the inner layer from cylinder thickness and decreased in the intermediate and outer layer , also decreased the grain size of primary silicon. The maximize volume fraction was in the inner layer from a cylinder thickness obtained at rotation speed (1878) r.p.m. and poring temperature (900)C? , where the values of volume fraction of ( ? - Si) phase are (35%) and obtained on completely functionally graded material. The results of micro structural observations showed that centrifugal casting process contributed to change the eutectic phase morphology from coarse needle - like structure to fibrous structure at increasing mold rotation speed but increased pouring temperature due to invert, and the results showed found thickness of (Si) particles in the metallic matrix decreased with increased rotation speed. The results of hardness tests to a cylinders samples showed maximum hardness values in the inner layer from cylinder thickness and increased with increasing mold rotation speed but it is decrease with increasing rotation speed. values hardness in all layers decrease with increasing pouring temperature. The results of wear tests showed maximum wear resistant was in the inner layer from cylinder thickness at rotation speed (1878) r.p.m. and poring temperature (800)C? and then coming outer layer but minimum wear resistant was in the intermediate layer.

Also had been studied the effect of pure nickel element on microstructure and on grain size and the types of phase that created in alloys produced by founding by using optical microscope , x - ray diffraction test device and a program that calculates the volume fraction of particles (J - image). So when we tested the hardness, the result showed that the alloy with highest adding rate (5% wt) have the best response between other alloys for hardening in longer time period and we reached to highest hardness (125 H.V) in time period (4hr) at (220 C?). While the alloy that doesn't have nickel reached to highest hardness equal to (112 H.V) in time period less than (2hr). The phases that created in alloys had been listed through analysis the x - ray diffraction and study the microstructure; we found the phase (Al7Cu4Ni) that be responsible on showing in alloy's response to precipitation hardening which leads to delay, also we found that the adding of nickel causes increase and improve in properties of tensile strength, yield strength and elongation, this is belong to presence of nickel that takes two ways, a part of it dissolves with Aluminum and copper and produce the phase (Al7Cu4Ni) which slows producing the phase (Al2CuMg), and other part refining grains size at highest temperature degrees that leads to increase in strength and hardness with higher rates for alloys contain nickel in comparison to those empty of nickel.

Composite materials prepared using stir casting method, where vortex technique help to draw the ceramic particles into the molten metal and distributed uniformly. The composite materials containing 4 wt% Cu and 1 wt% Mg, reinforced with different proportions wt% SiC (3,6,9,12) were cast in a metal mold. Magnesium was added to improve the wetability between SiC particles and the aluminum matrix. The base alloy and composite materials samples were tested to investigate microstructure, phases, and properties using Optical Microscope, X - Ray Spectrometer, Vickers Hardness, and Scanning Electron Microscope. The optical microscope and scanning electron microscope (SEM) are also used to study the effect of loads on the worn surface. From the results of microscopic examination on found that the alloy structure of the foundation is a fine dendrite structure (Dendrite), and after the addition of ceramic particles leads to an improvement in microstructure, in addition to distributed almost homogeneous in the matrix and on the boundaries crystalline. X - ray diffraction examination approved the existence of aluminum and silicon carbide phases. In addition to the deposition phase (Al2Cu) because of the natural aging,(Mg Al2Cu) phase and the presence of this freak indicate on the interaction of aluminum with the added elements, The hardness test results show that, the increasing the ceramic particles proportion tend to increase the hardness, the highest hardness found at 12wt% SiC. By studying the worn surface, using optical microscope and SEM, increasing in wear was observed with applied load for all reinforced particles percentage added. With the increased load, more wear, deep, and closed paths was formed. Twotypes of wear were monitored at high loads, adhesive wear and abrasive wear. The studying of wear rate for both base alloy and composites materials with various conditions, show that wear rate increase with increasing applied load, but the composite materials show higher wear resistant. The best wear resistance found at 12 wt% SiC addition.The studying of sliding speed show that the wear rate decreases with high speed the for both base alloy and composites materials. The sliding time show direct correlation with wear rate, but at continuous increasing sliding time, wear rate decline constantly.Statistical methods with software (Minitab 15) was used to study the effect of wear on weight loss for both the base alloy and composite material by using three variables; ( applied load (X1), silicon carbide proportion (X2), sliding distance (X3), with five levels of each variable. It was concluded that the optimum weight loss (Optimization of weight loss) (0.0046 g), as a result the wear process, are found at the these following levels of variables; applied load (2.5 N), sliding distance (7.2 Km) and at the silicon carbide proportion (3.6364 wt% Sic). Equation describes the combined effect of variables and the weight loss was obtained and which variable are more influential. Y = 0.010180 + 0.002825 X1 - 0.002375 X2 + 0.001100 X3 + 0.001809 X32 + 0.004700 X1 X3 + 0.002700 X2 X3 The applied load (X1) and sliding speed (X3) both have the largest effect on weight loss. Both, applied load and silicon carbide does not have any effect on the weight loss. For individual variable, it foundthat applied load has the greatest influence on weight loss.
