Using Alternative Cogeneration Plants in Iraqi Petroleum Industry

The present paper describes and analyses three proposed cogeneration plants include back pressure steam-turbine system, gas turbine system, diesel-engine system, and the present Dura refinery plant. Selected actual operating data are employed for analysis. The same amount of electrical and thermal product outputs is considered for all systems to facilitate comparisons. The theoretical analysis was done according to 1st and 2nd law of thermodynamic. The results demonstrate that exergy analysis is a useful tool in performance analysis of cogeneration systems and permits meaningful comparisons of different cogeneration systems based on their merits, also the result showed that the back pressure steam-turbine is more efficient than other proposals. Moreover, the results of the present work indicate that these alternative plants can produce more electric power than that required in the refinery. At present time, the industrial cogeneration plants are recommended in Iraq, especially in petroleum industry sectors, in order to contribute with ministry of electricity to solve the present crisis of electric power generation. Such excess in the power can sold to the main electric network. The economic analysis are proved the feasibility of the proposed cogeneration plants with payback period of four year and six months ,three year and eight months, and ten years for steam cogeneration plant, gas turbine cogeneration plant and diesel engine cogeneration plant respectively.

Alteration of Serum Immunoglobulin Levels in Woman with Ovarian Cancer

Ovarian cancer has a high mortality and delayed diagnosis. Several immunological alterations take place during ovarian carcinogenesis, and can be of value in the surveillance of the diseases. This research was conducted to evaluate serum immunoglobulin levels in women with ovarian cancer and to assess their role in disease process. The present study is composed of 85 women (mean age = 62.03±12.4 yrs) with clinically and pathologically confirmed ovarian cancer and 65 healthy females as a control group (mean age = 61±12.1 yrs). ELISA test was achieved for the determination of serum [IgG, IgA, IgM]. The findings of current study illustrated significant (P=0.001) increase in serum IgG, IgA, and IgM levels as compared to co

Meningitis in Baghdad 1993 – 1998 Part 1: Acute Bacterial Meningitis

Background: There is a need for a periodic review of acute bacterial meningitis (ABM) since the pathogens responsible for infection vary with time, geography and patient's age. This study was carried out to describe the epidemiology of different types of meningitis and variables affecting the outcome (improvement, complication and death).
Patients and Methods: All the cases of meningitis diagnosed and treated at Ibn- Al-Khateeb Teaching Hospital for the period Jan. 1993 to Dec. 1998 were included in this study. The collected data were age, sex, occupation, date of admission, date of discharge, type of meningitis and outcome of the disease.
Results: Out of the total cases, 73.3% were ABM. High rate of A

Epidemiology, Clinical characteristics, Laboratory Findings Of Bronchiolitis In Hospitalized Children

Background: Bronchiolitis is the most common disease of the lower respiratory tract during the first year of life. Which is usually caused by respiratory syncytial virus. The treatment is usually supportive, so epidemiology, clinical, laboratory, and radiologic findings might facilitate early diagnosis and treatment of bronchiolitis cases.

Objectives: The aim of our study was to evaluate the clinical characteristics and laboratory findings of children hospitalized due to bronchiolitis.

Patients and Methods: In this cross sectional study 143 patients with bronchiolitis were selected who age 1-24 months old who were admitted to the Fallujah teaching hospital for women and c

Protective Effect of Cafestol on Doxorubicin-induced Genotoxicity in Rats
Doxorubicin is an efficient antineoplastic agent that has a broad antitumour spectrum; however, its genotoxic adverse effects on normal cells can be produced through oxidative damage, and this limits its clinical application. Cafestol is a naturally-occurring diterpene in unfiltered coffee with noteworthy antioxidant, antimutagenic and anti-inflammatory activities.

The present study aimed to investigate the possible protective effect of cafestol against doxorubicin-induced chromosomal and DNA damage in rat bone marrow cells. Wistar

Albino rats of both sexes were administered cafestol (5mg/kg body weight once

Employ lean leadership behaviors to enhance investment in human capital

This research aims to determine the importance of the role that agile leadership plays in supporting programs and areas of investment in human capital, as it is the most important type of capital that the organization possesses and achieves returns that are many times the cost it bears, due to its rare and valuable characteristics. Through six behaviours: (humility behaviour, calm behaviour, wisdom behaviour, patience behaviour, objectivity behaviour, trust behaviour). As for investment in human capital, it was measured through its four elements (skills, knowledge, capabilities, experiences). Despite this, the researched organizations suffer from a decrease in awareness of the importance of this type of investment and the role of
