The need for an efficient method to find the furthermost appropriate document corresponding to a particular search query has become crucial due to the exponential development in the number of papers that are now readily available to us on the web. The vector space model (VSM) a perfect model used in “information retrieval”, represents these words as a vector in space and gives them weights via a popular weighting method known as term frequency inverse document frequency (TF-IDF). In this research, work has been proposed to retrieve the most relevant document focused on representing documents and queries as vectors comprising average term term frequency inverse sentence frequency (TF-ISF) weights instead of representing them as v

Summary:
Background: CM is the leading cause of infant deaths and account for much greater proportion of infant mortality’ than does premature birth. A malformation is a primary structural defect arising from a localized error in morphogenesis. This is a prospective study devoted to define the causes and frequencies of congenital malformations (CM) in Maternal and Children Hospital (MCH) in Al-Anbar govemorate (west of Iraq) and a comparison is done with other Iraqi and international studies.
FdC Med Baghdad Methods: Congenital malformations were studied over a period of 2 years from the 1st of July 2000 2007/ Vol. 49, No.3 f0 fjle 30th ofJune 2002 in 12831 births including stillbirths at MCH in Al- Anbar govemorate (west Receive

This review covers recent progress in the synthesis of curcumin and the bioactivity of semisynthetic and synthetic analogs of curcumin. The review also shows how curcumin is a useful intermediate for the synthesis of more complex organic molecules; historical perspective; the process of preparing the metal complexes and characterization the produced complexes using various spectral and other techniques; shows the importance of curcumin and its derivatives for their potential applications in medical devices and broad-spectrum of medical application such as antibiotic ointment, alternative therapeutics, antifungal, and antibacterial activities

Background: Infantile hypertrophic pyloric
stenosis affects 0.5 – 3.0 per 1000 live birth and it is
the most common surgical cause of vomiting in
infancy.
Objective: To analyze variable peri-natal factors
that may be involved in the etiology of infantile
hypertrophic pyloric stenosis.
Methods: Over a two year's period, from January
2000 – December 2001, 31 cases of infantile
hypertrophic pyloric stenosis were evaluated for
variable peri-natal risk factors in AL-Eskan central
child teaching hospital for children.
Results: The 31 cases studied were 77.4% males
and 48.4% at three weeks of age. And of all cases,
51.6% were breast fed with a blood group (O) being
the predominant in 54.8%.

Background: The morbidity and mortality of congenital diaphragmatic hernia is related to the severity of lung hypoplasia ,pulmonary hypertension and associated anomalies.
Patients and methods: fifty nine consecutive patients with surgically proved diaphragmatic hernia (excluding hiatal hernia) were included in this prospective study. All patients were seen at Al- Kadhymia hospital for children and Al-Mustansyria hospital, in the period from January 2003 to December 2009.Plain chest x-ray was done for all the patients understudy, but barium study was arranged for only nine patients.
Results: There were fifty nine child with congenital diaphragmatic hernia , Bochdalek hernia forms 81.4% of all congenital

Background: Congenital adrenal hyperplasia is a family of autosomal recessive disorders of cortisol biosynthesis. Depending on the enzymatic step that is deficient, there may be signs, symptoms, and laboratory findings of mineralocorticoid deficiency or excess; incomplete virilization or premature puberty in affected males; and virilization or sexual infantilism in affected females. The most frequent is 21-hydroxylase enzyme deficiency, accounting for more than 90% of cases.
Objectives: to review cases of congenital adrenal hyperplasia registered in children welfare teaching hospital- medical city- Baghdad.
Patients and method: This study included all patients who were presented and registered in the e

Background: Mothers are considered as the key role in effect on child's dental behavior. So it is important to involve her in oral health promotion program to prevent early childhood dental caries from occurring in early age. Objectives: To identify the knowledge, practice and attitude of mothers about the oral health of their children. And to measure the change in oral hygiene of children aged (4-7) years old after one month of interventional program on their mothers. Type of study: Non-randomized interventional.Methods: Non-randomized interventional study for one month in Al Shaab area in Baghdad to 65 mothers who have children aged (4-7) years .A modified administrated questionnaire is given to assess mothers’ knowledge, practice an

Load balancing in computer networks is one of the most subjects that has got researcher's attention in the last decade. Load balancing will lead to reduce processing time and memory usage that are the most two concerns of the network companies in now days, and they are the most two factors that determine if the approach is worthy applicable or not. There are two kinds of load balancing, distributing jobs among other servers before processing starts and stays at that server to the end of the process is called static load balancing, and moving jobs during processing is called dynamic load balancing. In this research, two algorithms are designed and implemented, the History Usage (HU) algorithm that statically balances the load of a Loaded

Alumina thin films have significant applications in the areas of optoelectronics, optics, electrical insulators, sensors and tribology. The novel aspect of this work is that the homogeneous alumina thin films were prepared in several stages to generate a plasma jet. In this paper, aluminium nanoparticles suspended in vinyl alcohol were prepared using exploding wire plasma. TEM analysis was used to determine the size and shape of particles in aluminium and vinyl alcohol suspensions; the TEM images showed that the particle size is 17.2 nm. Aluminium/poly vinyl alcohol (Al/PVA) thin films were prepared using this suspension on quartz substrate by plasma jet technique at room temperature with an argon gas flow rate of 1 L/min. The Al/PV
