The availability of low- cost adsorbent namely Al-Khriet ( a substance found in the legs of Typha Domingensis) as an agricultural waste material, for the removal of lead and cadmium from aqueous solution was investigated. In the batch tests experimental parameters were studied, including adsorbent dosage between (0.2-1) g, initial metal ions concentration between (50-200) ppm (single and binary) and contact time (1/2-6) h. The removal percentage of each ion onto Al-Khriet reached equilibrium in about 4 hours. The highest adsorption capacity was for lead (96%) while for cadmium it was (90%) with 50 ppm ions concentration, 1 g dosage of adsorbent and pH 5.5. Adsorption capacity in the binary mixture were reduce at about 8% for lead and 12 % for cadmium, which was attributed to competitive adsorption. The adsorption parameters were analyzed using both the Freundlich and Langmuir. Al-Khriet was best fitted by the Freundlich isotherm comparing with Langmuir model, and the rate constant was found to be 1.305 and 0.621 ((mg/g)(L/mg)1/n) for lead and cadmium respectively , while the kinetic of adsorption obeyed a second order rate equation and the rate constants were found to be (0.0161) for lead and ( 0.0125) mg.g-1.min-1 for cadmium.

This study has dealt with, the issue of classification of rural road network , in addition to prepare a suggested for the classification for this network in Iraq , this classification account , the specifications and characteristics of rural roads, population, and the range taking of settlements , then this classification was applied on the rural road network in the Najaf province there are four categories of classification ,the first is major arterial rural roads divided into two major arterial and minor arterial roads , while the second category collected roads which was divided into minor arterial roads and main collected roads. The third category was represented by Local Roads , it has been divided into paved roads and unpaved, the f

The performance of the field irrigation system was evaluated on two fields of different crops and irrigation methods according to the agricultural reality of the study area in the Western canal for the Al-Ishaqi Irrigation Project in Salah Al-Din Governorate. The fieldwork included measurements of the moisture content before and after irrigation, fi

Praise be to God, Lord of the worlds, and prayers and peace be upon our Prophet Muhammad and his family and companions. And after:
For one of the greatest blessings of God Almighty upon us is the blessing of Islam, which brought people from darkness to light and from injustice and fear to security, justice, stability, and the preservation of blood, symptoms, rights, and sacrifices, because pride, strength, and dignity are what God chose and pleases His servants - namely - adherence to the Islamic religion, and in light of This must be said that the private legal defense (pushing the person) with its Islamic provisions and legislations is one of the great aspects that guarantees the establishment of a safe
Objectives: To report the Cesarean section rate in Al-
Batool Maternity Teaching Hospital and to identify
how many of them were done for maternal and fetal
condition.
Design: A statistical cross sectional study.
Setting: The study was conducted at Al-Batool
Maternity Teaching Hospital (13000 deliveries per
year).
Participants: The patients group consists of 4556
patients admitted for delivery (vaginal and abdominal)
during a period of four months commencing from
January 2003.
Main outcome measures: calculation of all live
births, calculation of cesarean section rate, percentage
of the primary cesarean sections and the repeat
cesarean sections and listing the indications of the
operation acc
The aim of this research is to develop mechanical properties of a new aluminium-lithium-copper alloy. This alloy prepared under control atmosphere by casting in a permanent metal mould. The microstructure was examined and mechanical properties were tested before and after heat treatment to study the influence of heat treatment on its mechanical properties including; modulus of elasticity, tensile strength, impact, and fatigue. The results showed that the modulus of elasticity of the prepared alloy is higher than standard alloy about 2%. While the alloy that heat treated for 6 h and cooled in water, then showed a higher ultimate tensile stress comparing with as-cast alloy. The homogenous heat treatment gives best fatigue

Abstract
The main goal of this study is to showcase the aesthetic values contained in Nahj Al-Balagha by exploring its wide horizons and enriching the subject of rhetoric with new forms and images that did not exist in other books, as they characterized no other book but Nahj Al-Balagha. Imam Ali mastered the use of rhetorical forms in his speech to the fullest extent that such forms raced to his thought one after the other to book their place amongst the topics of religious and earthly life. One of those rhetoric forms is synecdoche, in its various parts. Due to this form great importance and high status, it was used by the Imam at many

Abstract
Praise is to God and Prayers and peace is upon the Messenger of Allah and his family and companions and then:
The research here presents to the question of standing on the purpose of belief and its importance, which corresponds to going into the purposes of the Sharia acts and Worship, which are no less important and perhaps the most important. The health of belief is the only way to correct work and worship. The research first dealt with the definition of the doctrine and its pil

Contradicting his predecessor Plato on the issue of „truth,‟ Aristotle believed that „poetry is more philosophical and deserves more serious attention than history: for while poetry concerns itself with universal truths, history considers only particular facts.‟ (1) The critical attention to the disparity between the literary truth and the historical truth grew up throughout ages to flourish in the Renaissance and after with a bunch of distinctive views on this subject. Sir Philip Sidney (1554-1586), for example, found that literature does not offer a literal description of reality but rather a heightened vers
