A practical study of the problems of queues for vehicles in some filling stations in the city of Baghdad
...Show More Authors

 According to the circumstances experienced by our country which led to Occurrence of many crises that are the most important crisis is gaining fuel therefore , the theory of queue ( waiting line ) had been used to solve this crisis and as the relevance of this issue indirect and essential role in daily life  .

This research aims to conduct a study of the distribution of gasoline station in (both sides AL – kharkh and AL Rusafa, for the purpose of reducing wasting time and services time through the criteria of the theory of queues and work to improve the efficiency of these stations by the other hand. we are working to reduce the cost of station and increase profits by reducing the active service unit so that do sent affect the process of waiting and the time of performance services.   the possibility of applying more than statistical distribution of data acess rate and the rate of services and best selection of distribution which reducing the time of service through statistical techniques to demonstrate the behavior of the data
(access rate and service rate) with in the statistical distribution that are consistent with the nature of data and select the best statistical distribution which affects the theory of the queues during the time of service and waiting time there are three categories for better know ledge of distribution are

 

  1. Poisson with Exponential
  2. Poisson with Weibull
  3. Erlang with Exponential

 

Asset of on clusion had been emerged from the study as using such
(G /G /C) queue model which includes the use through the current reality stations like AL– idrisi, AL– Mustansiriya and AL– galani the waiting time for the customer of services is mostly doesn’t have time to wait therefore, we suggest reducing the number of units in station and increase profit through the groups note that the distribution stations animate the few number of unit operating station such as AL– karkh (AL- khadra, AL– yarmouk and AL– shorta al– ola) the data access and service distributed according to the distribution of Poisson with Weibull the data access Service and distributed according to Poisson With Weibull station do the large number of units operating station such as
AL– Rusafa  (AL– idrisi, AL– Mustansiriya and AL– galani ) the data access and service distribution according to the distribution of Poisson with Exponential and Poisson with Weibull   .

Advanced Study of Promoted Pt /SAPO-11 Catalyst for Hydroisomerization of the n-Decane Model and Lube Oil
...Show More Authors

   SAPO-11 is synthesized from silicoaluminophosphate in the presence of di-n-propylamine as a template. The results show that the sample obtained has good crystallinity, 396m2/g BET surface area, and 0.35 cm3/g pore volume. The hydroisomerization activity of (0.25)Pt (1)Zr (0.5)W/SAPO-11 catalyst was determined using n-decane and base oil. All hydroisomerization experiments of n-decane were achieved at a fixed bed plug flow reactor at a temperature range of 200-275°C and  LHSV 0.5-2h-1.  The results show that the n-decane conversion increases with increasing temperature and decreasing LHSV, the maximum conversion of 66.7 % was achieved at temperature 275°C and LHSV of 0.5 h-1

Study of ELISA and antibiotic sensitivity test for Salmonella enteritidis as experimental infection in mice
...Show More Authors

Salmonella enteritidis one of more important as epidemiological bacteria between other salmonella types. It is very important pathologically that cause food poising and gastrointestinal tract infections. This study includes some of immunological changes that appear by ELISA test and antibiotic sensitivity test against these bacteria in mice. ELISA test results appears high immunological response happen after 3 days of inoculation, mean titration readings beginning 0.198 and the maximum mean titration after 15 days of inoculation 1.538 and begin to decrease after this time slowly to remain about 0.297 after 40 days of inoculation. An antibiotics sensitivity test result appears, this bacteria sensitive to Chloramphenicol, Ceftriaxone,

Study of nuclear structure for carbon isotopes using local scale transformation technique in shell model
...Show More Authors

This work is devoted to study the properties of the ground states such as the root-mean square ( ) proton, charge, neutron and matter radii, nuclear density distributions and elastic electron scattering charge form factors for Carbon Isotopes (9C, 12C, 13C, 15C, 16C, 17C, 19C and 22C). The calculations are based on two approaches; the first is by applying the transformed harmonic-oscillator (THO) wavefunctions in local scale transformation (LST) to all nuclear subshells for only 9C, 12C, 13C and 22C. In the second approach, the 9C, 15C, 16C, 17C and 19C isotopes are studied by dividing the whole nuclear system into two parts; the first is the compact core part and the second is the halo part. The core and halo parts are studied using the

Woman's Quest for Survival: Margret Drabble's The Millstone
...Show More Authors

This study deals with The Millstone (1965) which is a dramatic depiction of a single
mother heroine in a classic predicament. This novel is considered as representative of the age
in which it was written. The primary theme is her intense preoccupation with questions of
fatalism and will. The work also involves, both explicitly and implicitly, feminist concerns.
Because the central protagonist is a woman and the society in which she lives is depicted,
accurately, as deeply patriarchal and class-bound, the problem of the individual's capacity for
self-determination is inevitably tied to the feminist perspective.

...Show More Authors

Mercury, arsenic, cadmium and lead, were measured in sediment samples of river and marine environmental of Basra governorate in southern of Iraq. Sixteen sites of sediment were selected and distributed along Shatt Al-Arab River and the Iraqi marine environment. The samples were distributed among one station on Euphrates River before its confluence with Tigris River and Shatt Al-Arab formation, seven stations along Shatt Al-Arab River and eight stations were selected from the Iraqi marine region. All samples were collected from surface sediment in low tide time. ICP technique was used for the determination of mercury and arsenic for all samples, while cadmium and lead were measured for the same samples by using Atomic Absorption Spectrosc
