Applying Penman-Monteith Equation to Evaluate the Performance of Atmometer Apparatus in Greenhouse for Estimating Reference Evapotranspiration
...Show More Authors

In this paper an atmometer apparatus were used in the greenhouses for estimating reference evapotranspiration values. Experimental work was conducted in the agriculture research center in the College of Agriculture-University of Baghdad west of the city of Baghdad. One atmometer was used in eggplant greenhouse and in cucumber greenhouse through the winter growing season 2013-2014. FAO Penman-Monteith equation was applied outside the greenhouse and used only 65% from the value of ETo in the greenhouses for estimating the reference evapotranspiration in the greenhouse. Moreover, Penman-Monteith equation was applied in greenhouses for the evaluating the performance of the atmometer. The results show that the error analyses between FAO Penman-Monteith equation in greenhouse and the atmometer readings, the root mean square difference (RMSD), mean bias error (MBE) and relative error (RE) for eggplant and cucumber greenhouses were: 1.163mm/day, 0.933mm/day, 30.19%, and 0.688mm/day, 0.518mm/day and 22.93%, respectively. A fair agreement was found. While the error analyses between 65% from outdoor ETo of FAO Penman-Monteith equation and the atmometer readings, the RMSD, MBE and RE for eggplant and cucumber greenhouses were: 0.930mm/day, 0.743mm/day, 24.27%, and 0.374mm/day, 0.289mm/day and 12.47%, respectively. A good agreement was found. The atmometer apparatus could be used successfully by researchers and farmers in estimation daily or weekly reference evapotranspiration in greenhouses as well as in low technology greenhouses.

Smart grid in the context of industry 4.0: an overview of communications technologies and challenges
...Show More Authors

The recent advances in technology, the increased dependence on electrical energy and the emergence of the fourth industrial revolution (Industry 4.0) were all factors in the increased need for smart, efficient and reliable energy systems. This introduced the concept of the Smart Grid (SG). A SG is a potential replacement for older power grids, capable of adapting and distributing energy based on demand. SG systems are complex. They combine various components and have high requirements for real time reliable operation. This paper attempts to provide an overview of SG systems, by outlining SG architecture and various components. It also introduces communication technologies, integration and network management tools that are involved in SG sys

Implications of Financial Reporting Governance in rationalizing investors decisions In financial markets in light of An International Financial Reporting Standards (IFRS)/ An analytical study of a selected sample of the joint stock companies in Iraq
...Show More Authors

The financial crises that occurred in South East Asia and America, and the discovery of the financial and administrative corruption that affected these companies, which led to the crisis. Since then, organizations and institutions interested in accounting have begun new ways to further rationalize the management of these companies. Hence the concept of governance, which means good governance. Al-Susiya confirmed its adoption of the financial reporting standards and adopted internal and external auditing for the purpose of increasing the reliability and credibility of the financial and reports that increase the confidence of investors in making their investment decisions in the financial markets The study dealt with the contributi

The Deeper Wounds: Living in the Trauma Zone in Jawad Al-Assadi’s Baghdadi Bath and Mithal Ghazi’s A Feminine Solo
...Show More Authors

Various literary studies have investigated the psychological, social and cultural effects of traumatic events. They give voice to traumatised victims and enable them to convey and confront their traumas. However, these studies present a one-sided view, concentrating largely on the presentation of trauma in the industrial societies of the Western world. Recently, increasing attention has been devoted to identifying and depicting the forms and types of trauma that have been experienced in marginalised and neglected societies, such as the Iraqi society. Iraq has witnessed the unexpected fall of a brutal dictatorship, Western invasion and an unprecedented rise of sectarian discourses. This extreme violence has deeply affected many aspec

FOOD APPLICATIONS FOR OIL AND CHIA SEEDS SALVIA HISPANICA: FOOD APPLICATIONS FOR OIL AND CHIA SEEDS SALVIA HISPANICA
...Show More Authors

The extracted oil from the Chia seeds white and black were used in the manufacture of certain foods such as mayonnaise. The results of the sensory evaluation showed that the product was acceptable except for the flavor of white chia seed oil. The seeds were fully used in the manufacture of the nutella. The results of the sensory evaluation were encouraging the use of the extracted oil from the black chia seeds in the production of the nutella except the spread property. Chia seeds were also used in the manufacture of pudding. The results of the sensory evaluation showed an excellent and acceptable product of black chia seeds oil can be obtained, while the white seeds did not receive the acceptance in terms of color and flavor.

Simulation Study on Optically Designed Refractive Beam Expander for Nd: YAG Laser Harmonics for 7 Km Detection Range
...Show More Authors

The simulation study has been conducted for the harmonics of Nd: YAG laser, namely the second harmonic generation SHG, the third harmonic generation THG, and the fourth harmonic generation FHG. Determination of beam expander's expansion ratio for specific wavelength and given detection range is the key in beam expander design for determining minimum laser spot size at the target. Knowing optimum expansion ratio decreases receiving unit dimensions and increases its performance efficiency. Simulation of the above mentioned parameters is conducted for the two types of refractive beam expander, Keplerian and Galilean. Ideal refractive indices for the lenses are chosen adequately for Nd: YAG laser harmonics wavelengths, so that increasing transm

Prediction Unconfined Compressive Strength for Different Lithology Using Various Wireline Type and Core Data for Southern Iraqi Field
...Show More Authors

Unconfined Compressive Strength is considered the most important parameter of rock strength properties affecting the rock failure criteria.  Various research have developed rock strength for specific lithology to estimate high-accuracy value without a core.  Previous analyses did not account for the formation's numerous lithologies and interbedded layers. The main aim of the present study is to select the suitable correlation to predict the UCS for hole depth of formation without separating the lithology. Furthermore, the second aim is to detect an adequate input parameter among set wireline to determine the UCS by using data of three wells along ten formations (Tanuma, Khasib, Mishrif, Rumaila, Ahmady, Maudud, Nahr Um

The present work was aimed to form the baseline data of normal morphological and histological structure features of liver in migratory starling (Sturnus vulgaris). Anatomically, the starling liver bird was dark red -brown in colour and located in the cranial third of the abdominal cavity and consisted of undivided lobes (left and right). The liver right lobe was larger than the left. Histological examination revealed that the liver parenchyma was covered by a connective tissue capsule which appears to be thicker in the rim of liver lobes than other area in the liver lobe. Liver parenchyma was arranged in an unlimited hepatic lobules, which composed of polygonal hepatocytes organized as irregular, radial interconnecting cords or laminae of o
