Praise be to God, Lord of the worlds, and peace and blessings be upon our master Muhammad, and upon his whole family and companions, but after: God Almighty has instituted types of acts of worship and classes of obedience that, if performed by the servant, would link him with his Creator and connect with his Lord. And for the sake of these worship, and the greatest of them: the worship of i'tikaaf, for souls need rest and recuperation from the struggle of life and its concerns, concerns and anguish, and people differ in their attitudes and interests in the means of recreation, and many people consider the outing and travel the best way in which they breathe from their toil and toil, and reclaim their strength and the advised adult He finds that the best way for him to relax and live in peace with her calm and reassuring is the remembrance of God Almighty: لا Do not the remembrance of God rest assured of hearts (). And his complete happiness is to take refuge in the homes of God and its neighborhoods through prayer, remembrance and retreat. In the vastness of God’s homes, the believer takes pleasure in unparalleled enjoyment, goes to an unparalleled comfort, and emerges from his distress unscathed with contentment and surrender, and discloses that infallible: A group weakens his prayer in his home, and in his market twenty-five degrees, because if he performs ablution
He did good ablution, then he went out to the prayer, and he does not take it out except the prayer. Prayer)( ) . In the confines of prayer, a person harms himself to a strong corner, wielding him from error, and helps him with the misfortunes of eternity, and guides him to the right path: O those who believe, seek patience and pray, for God is with those who are patient ()). And if walking to prayer and waiting for prayer raises one to high positions and high levels, then staying in mosques and observing there days and nights rises to the servant to the point of peasantry, the Prophet says : (And whoever observes a day seeking the face of God, God makes between him and the fire three trenches, each trench Beyond the beater) (). I'tikaaf and the need for obedience to the mosques are one of the closest angels who do not deflect from the worship of God, and the one who remembers his remembrance of God is close to his master, and he is happy and happy. For the sake of all this, this humble research, marked with (Explanation of the Book of I'tikaaf from the Orphaned Dura System) came to the scholar Imam al-Sarasri al-Hanbali, may God Almighty have mercy on him, and the reason for choosing this system is due to two things:
1- The ease of preserving the system for the seeker of Islamic knowledge.
2- The great status of the author, may God have mercy on him, among Hanbalis and among Muslim scholars in general.
This system has been printed recently, and through my extensive search for explanations for it, I did not stand for an explanation of it, so I liked that my explanation of the book on i'tikaaf should be the beginning of an explanation of this great, great destiny revealed .. And the last of our prayers is that praise be to God, Lord of the Worlds.
Cadmium is one of the heavy metal found in the wastewater of many industries. The electrocoagulation offers many advantages for the removal of cadmium over other methods. So the removal of cadmium from wastewater by using electrocoagulation was studied to investigate the effect of operating parameters on the removal efficiency. The studied parameters were the initial pH, initial concentration, and applied voltage. The study experiments were conducted in a batch reactor with with two pairs of aluminum electrodes with dimension and 2mm in thick with 1.5 cm space between them. The optimum removal was obtained at pH =7, initial concentration = 50 mg/L, and applied voltage = 20 V and it was 90%.

Wastewater recycling for non-potable uses has gained significant attention to mitigate the high pressure on freshwater resources. This requires using a sustainable technique to treat natural municipal wastewater as an alternative to conventional methods, especially in arid and semi-arid rural areas. One of the promising techniques applied to satisfy the objective of wastewater reuse is the constructed wetlands (CWs) which have been used extensively in most countries worldwide through the last decades. The present study introduces a significant review of the definition, classification, and components of CWs, identifying the mechanisms controlling the removal process within such units. Vertical, horizontal, and hybrid CWs

The aim of this study is to propose mathematical expressions for estimation of the flexural strength of plain concrete members from ultrasonic pulse velocity (UPV) measurements. More than two hundred pieces of precast concrete kerb units were subjected to a scheduled test program. The tests were divided into two categories; non-destructive ultrasonic and bending or rupture tests. For each precast unit, direct and indirect (surface) ultrasonic pulses were subjected to the concrete media to measure their travel velocities. The results of the tests were monitored in two graphs so that two mathematical relationships can be drawn. Direct pulse velocity versus the flexural strength was given in the first relationship while the second equation des

Fifty three hydatid cysts were collected from different hosts, sheep, goats and cattle , from many slaughterhouse in Salahadin and Baghdad , while human's hydatid cysts samples were collected from Tikrit educational hospital and Tofiqe civilian hospital patients . The study included a biochemical comparison of some hydatid cyst fluid criteria such as, glucose, total protein, pH, glutamate pyrovate transaminase enzyme (GPT) , glutamate oxaloacetate transaminase enzyme (GOT) , acid phosphatase (ACP) , Alkaline Phosphatase (ALP) , and also studied protoscolices viability,the current study showed the differences in chemical composition of hydatid cyst fluids back to host type and parasite strain .

The extraction of iron from aqueous chloride media in presence of aluminum was studied at different kinds of extractants(cyclohexanone, tributyl phosphate, diethyl ketone), different values of normality (pH of the feed solution), agitation time, agitation speed, operating temperature, phase ratio (O/A), iron concentration in the feed, and extractant concentration]. The stripping of iron from organic solutions was also studied at different values of normality (pH of the strip solution) and phase ratio (A/O). Atomic absorption spectrophotometer was used to measure the concentration of iron and aluminum in the aqueous phase throughout the experiments.The best values of extraction coefficient and stripping coefficient are obtained under the

Twenty isolates of Serratia marcescens were isolated from inflammation of the urinary tract (UTI)., These isolates were found to produce hemolysin as indicated by blood agar plates in which the hemolysis of red blood cell indicate a positive result. Isolates were selected according to their hemolysis activity by measuring absorbance of hemoglobin at 405 nm that released from red blood cell. Hemolysin was completely purified using 50-75% saturation of ammonium sulphate followed by ion exchange chromatography with DEAE-cellulose then gel filtration chromatography by sepharose 4B. Accordingly molecular weight for the purified toxin was estimated as 45 KD.
