The research aims to identify the availability of some basic competencies that are required to be available to workers in digital agricultural Extension from the point of view of senior management, middle management, and, employees with Post-graduate education degrees, represented by the following: Transition to digital agricultural Extension for sustainable and smart family farms, benefiting from international expertise and experiences in applying for Digital agricultural Extension, preparing and implementing Extension messages through platforms, factors affecting the effectiveness of digital agricultural Extension and its platforms, following up and evaluating the activities and programs of the digital Extension platform. The research population included agricultural Extension workers in senior management, middle management, and employees with Post-graduate education degrees in some of the governorates of the central region of Iraq, namely Baghdad, Holy Karbala, and Babel. A random sample was taken from the Post-graduate. The senior management, reached 46 respondents by 35%%, and 16 respondents, while the entire population was taken for senior management, which numbered 2, and the middle management, which numbered 41, and thus the sample subject to research became 59 respondents. A questionnaire was used to collect data from the respondents, consisting of 48 items, distributed over five areas: the transition to digital agricultural Extension for sustainable and smart family farms, benefiting from international expertise and experiences in the application of digital agricultural Extension, preparing and implementing Extension messages across platforms, factors Influencing the effectiveness of digital agricultural Extension and its media, following up and evaluating the activities and programs of the digital Extension platform at 11, 9, 10, 7, and 11 items, respectively, according to a quintuple scale, and the weighted mean, the weighted percentage, was used. The research concluded that there is a discrepancy in the respondents’ answers in the paragraphs of the five domains about the availability of some basic competencies among workers in digital agricultural Extension, which range from important to very important according to the scale of the importance level of quintiles, the highest value of which is 4 degrees and the lowest is zero, with a weighted average of the total for the five mentioned domains 3.25, 3.42 , 3.42, 3.42, 3.33 degrees and respectively The researcher recommends the necessity and importance of building human capital through the consolidation of these competencies through the continuous development and training of workers in digital Extension
Sub-threshold operation has received a lot of attention in limited performance applications.However, energy optimization of sub-threshold circuits should be performed with the concern of the performance limitation of such circuit. In this paper, a dual size design is proposed for energy minimization of sub-threshold CMOS circuits. The optimal downsizing factor is determined and assigned for some gates on the off-critical paths to minimize the energy at the maximum allowable performance. This assignment is performed using the proposed slack based genetic algorithm which is a heuristic-mixed evolutionary algorithm. Some gates are heuristically assigned to the original and the downsized design based on their slack time determined by static tim

A numerical investigation of mixed convection in a horizontal annulus filled with auniform fluid-saturated porous medium in the presence of internal heat generation is carried out.The inner cylinder is heated while the outer cylinder is cooled. The forced flow is induced by thecold outer cylinder rotating at a constant angular velocity. The flow field is modeled using ageneralized form of the momentum equation that accounts for the presence of porous mediumviscous, Darcian and inertial effects. Discretization of the governing equations is achieved usinga finite difference method. Comparisons with previous works are performed and the results showgood agreement. The effects of pertinent parameters such as the Richardson number and internalRay

<span lang="EN-US">Iraqi people have been without energy for nearly two decades, even though their geographic position provides a high intensity of radiation appropriate for the construction of solar plants capable of producing significant quantities of electricity. Also, the annual sunny hours in Iraq are between 3,600 to 4,300 hours which makes it perfect to use the photovoltaics arrays to generate electricity with very high efficiency compared to many countries, especially in Europe. This paper shows the amount of electric energy generated by the meter square of crystalline silicon in the photovoltaic (PV) array that already installed in 18 states in Iraq for each month of the year. The results of the meter-square of PV arr

We propose a new method for detecting the abnormality in cerebral tissues present within Magnetic Resonance Images (MRI). Present classifier is comprised of cerebral tissue extraction, image division into angular and distance span vectors, acquirement of four features for each portion and classification to ascertain the abnormality location. The threshold value and region of interest are discerned using operator input and Otsu algorithm. Novel brain slices image division is introduced via angular and distance span vectors of sizes 24˚ with 15 pixels. Rotation invariance of the angular span vector is determined. An automatic image categorization into normal and abnormal brain tissues is performed using Support Vector Machine (SVM). St

Show MoreThere are many varied studies that dealt with the dramatic construction, especially books and studies that addressed drama in its construction and the method of writing it, that no textbook or a general cultural content is void of tackling the dramatic text in its construction and how the dramatic action develops in it. Therefore, a question occurs to the mind about the feasibility of dealing with the dramatic construction in this time, where many contemporary studies of dramatology and its relation and the contemporary critical directions are accumulating. This question many have two realistic aspects, yet the novelty and originality that this research shows lie in addressing a refined linguistic text in its style and connotations, such
