The Role of Environmental Auditing in Achieving Sustainable Development: Management Systems as a Mediator

The present study tackles the complex issue of the urgent need for Environmental Auditing (EA) in Iraq in the absence of laws that support environmental management and in the light of the high rates of cancerous diseases in Iraq, which coincided significantly with the increase in oil production, according to the numbers indicated in the Iraqi Ministry of Health. The study aimed to investigate the mediating role of Management Systems (MS) related to the role of EA supporting sustainability reports concerning the reduction of the negative effects of gas emissions from oil companies. We adopted the descriptive approach which relies on studying relationships through a questionnaire that was distributed to a group of workers at Doura Refinery in Baghdad for refining oil. The number of workers was 155 people who are specialized in administrative and financial aspects, let alone some other supporting specializations in the refinery selected. In designing the questionnaire. This organization was chosen due to its being one of the organizations that cause significant pollution in Baghdad depending on government reports, which indicate the lack or weak weakness of the procedures taken by the refinery administration to reduce carbon dioxide emissions. The study reached the conclusion that MS mediate the relationship between EA and sustainable development (SD). The EA also has a significant impact on achieving SD. Depending on the bibliometric survey conducted, this study is the first in Iraq, a matter that gives the research a great interest in the field of research on SD topics.

A Hyperbolic Potential Field Model for Designing an Einzel Lens of Low Aberrations

An analytical model in the form of a hyperbolic function has been suggested for the axial potential distribution of an electrostatic einzel lens. With the aid of this hyperbolic model the relative optical parameters have been computed and investigated in detail as a function of the electrodes voltage ratio for various trajectories of an accelerated charged-particles beam. The electrodes voltage ratio covered a wide range where the lens may be operated at accelerating and decelerating modes. The results have shown that the proposed hyperbolic field has the advantages of producing low aberrations under various magnification conditions and operational modes. The electrodes profile and their three-dimensional diagram have been determined whi

Theoretical Evaluation of Solar Assisted Desiccant Cooling System for a Small Meeting-Hall

The performance of a solar assisted desiccant cooling system for a meeting-hall located in the College of Engineering/University of Baghdad was evaluated theoretically. The system was composed of four components; a solar air heater, a desiccant dehumidifier, a heat exchanger and an evaporative cooler. A computer simulation was developed by using MATLAB to assess the effect of various design and operating conditions on the performance of the system and its components. The actual weather data on recommended days were used to assess the load variation and the system performance during those days. The radiant time series method (RTS) was used to evaluate the hourly variation of the cooling load. Four operation modes were employed for perform

Study of Interaction between Vitamin C and Nickel () Ion using a Polarographic Methods

The Polarographic study of the interaction between ascorbic acid and Ni+2 was carried out at dropping mercury electrode [DME] . This study included the determination of the kinetic parameters (kfh ,n) and thermodynamic parameters such as enthalpy change (H), free energy change (G) and entropy change (S) of Ni+2 complexes with ascorbic acid in 0.1 M KCl solution over the temperature rang of (294-309)K. The electrode processes were irreversible and diffusion controlled.

Treatment of perniosis with oral tadalafil, pentoxifylline or prednisolone A therapeutic comparative study

Background: perniosis is a common dermatological problem. Different modalities of treatment are available with conflicting results and no single effective therapy is universally accepted.
Objective: To evaluate the effectiveness of oral tadalafil and compare it with pentoxyfylline or prednisolone in treatment of perniosis
Patients and methods: This was a therapeutic comparative trial conducted in the department of Dermatology, Baghdad Teaching hospital, Baghdad, Iraq between November 2011 and March 2014.
Fifty eight patients with perniosis were enrolled in this study, and divided into 3 groups. Group (A) comprised 19 patients who received oral tadalafil (5 mg once daily); group (B) comprised 18 patients who received pentoxifylli

Study of Acute and Chronic Sinusitis – Symptoms, Diagnosis and Treatment: A Review article

Background: Sinusitis is an inflammatory condition that affects the mucous membrane lining the airways. Chronic rhinosinusitis and acute rhinosinusitis are the two types. Rhinosinusitis is characterized by facial pain, congestion, and headache. Due to the widespread prevalence of sinusitis, there must be an evaluation of the case because the diagnoses are more serious in the advanced stages of the disease and impact the outcome of care. Objectives: The objective of this study was to conduct a literature evaluation of chronic and acute rhinosinusitis, risk factors, symptoms and signs of sinusitis, diagnostic, sinusitis treatment, and antibiotic treatment, as well as new databases. Conclusion:

Surface Plasmon Resonance (SPR) Simulation of a Gold-Bismuth Bi-layer Gas Sensor

      The features of plasmonic surface frequency sensor technology, such as the small number of sensor samples required, electromagnetic interference, and high sensitivity, have been found to be highly important.. In this paper, a simulation program was created in Matlab_b2018 by adopting Fresnel equations for calculating the reflectivity of the electromagnetic wave between different media. A surface plasmon resonance sensor based on electromagnetic wavelengths within the range (100 nm to 1000 nm) has been proposed. The transfer matrix was used for a system consisting of four different media. The first medium is a semicircular BK7 glass prism, the second medium is a gold layer (40 nm thick), then a bismuth layer of variable thickne

Spectrophotometric Method for Determination of Cu(II) Using a New Schiff Base Ligand

The Cu(II) was found using a quick and uncomplicated procedure that involved reacting it with a freshly synthesized ligand to create an orange complex that had an absorbance peak of 481.5 nm in an acidic solution. The best conditions for the formation of the complex were studied from the concentration of the ligand, medium, the eff ect of the addition sequence, the eff ect of temperature, and the time of complex formation. The results obtained are scatter plot extending from 0.1–9 ppm and a linear range from 0.1–7 ppm. Relative standard deviation (RSD%) for n = 8 is less than 0.5, recovery % (R%) within acceptable values, correlation coeffi cient (r) equal 0.9986, coeffi cient of determination (r2) equal to 0.9973, and percentage capita

TREATMENT OF A HIGH STRENGTH ACIDIC INDUSTRIAL CHEMICAL WASTEWATER USING EXPANDED BED ADSORBER

Treatment of a high strength acidic industrial wastewater was attempted by activated carbon
adsorption to evaluate the feasibility of yielding effluents of reusable qualities. The experimental
methods which were employed in this investigation included batch and column studies. The
former was used to evaluate the rate and equilibrium of carbon adsorption, while the latter was
used to determine treatment efficiencies and performance characteristics. Fixed bed and expanded
bed adsorbers were constructed in the column studies. In this study, the adsorption behavior of acetic acid onto activated carbon was examined as a function of the concentration of the adsorbate, contact time and adsorbent dosage. The adsorption data was mo
