يبقى الفن ولا زال في جميع حالات التعاقب البشري ومراحل التطور الانساني الاكثر انطلاقة وتميزاً في التعبير عن واقع الانسان وعن مشاعره وانفعالاته وافكاره ذات الصلة بتأثيرات البيئة المحيطة به.

والفن ولاسيما (الرسم) يمثل وسيلة من وسائل التعبير الفني بل يكاد يكون الرسم وسيلة الانسان الاولى التي عبر فيها بخطوط مرئية عن مجالات حياته وعلاقته بالبيئة التي عاش فيها، ويقيناً ان الخطوط هذه وكما شكلتها يد الانسان وظهرت بصيغة رموز وصور ذات دلالات او معانٍ عبرت عن انفعالاته واهتماماته وحالته النفسية الداخلية من جهة، وعلاقته بالبيئة التي يعشيها بجميع ظواهرها الاجتماعية والطبيعية من جهة اخرى، في اشكال ظهرت في البداية على جدران الكهوف والقصور والمعابد والمنازل التي استخدمها كاوراق للرسم عليها وفيما تركه ذلك من ادلة على التعبير الفني لمكونات بيئته.

ومع ان وسائل الرسم وطرائق التعبير عنه قد تعددت وتنوعت عبر الاف السنين الا ان ميزة التفرد الرئيسة للرسم ظلت وستبقى تمثل حاجة نفسية يلجأ اليها الانسان بوصفها الوسيلة الاقرب وضوحاً الى نفسه والاعمق اثراً في وجدانه، كون ان الرسم من اكثر الفنون تماساً بملامح حياته ومن اشدها تأثيراً بشعوره وادراكه بدليل ان الحضارات الانسانية سعت ولقرون عديدة الى ان تعبر عن تجربتها الانسانية بالرسوم التي ينجزها ابناؤها.

ان هذا التوجه يعزز القناعة بفاعلية تلك الرسوم وفي تهيئة ذلك الترابط بين الانسان وما يعتمل في نفسه وفي كل ما في بيئته من مظاهر واشكال وما تحتويه من مشاهد تتمثل في رسومه وفي رؤيته ونظراته الى البيئة وتذوق مظاهرها وما يحسه من اشكال الشخوص والكائنات الحيوانية والنباتية والحوادث التي يريد التعبير عنها.

ويشير (هربرت ريد – 1975) بهذا الصدد الى ان "الفن استعداد متوافر لدى الافراد بدرجات متفاوتة ويطبقونه في كل ما يقع تحت احاسيسهم وعواطفهم ومشاعرهم في حياتهم اليومية، وهو يكشف القيم الجمالية، فبواسطته نستطيع ان نتعرف على مكامن الجمال والقبح والتمييز بينهما في الاشياء التي تقع بالبيئة المحيطة بنا، وكذلك فانه ينمي الذوق والاحساس بالجمال وينمي الوجدان كونه متغلغل في حياة الانسان منذ القدم اذ اصبحت كل الاشياء التي يصنفها الانسان خاضعة الى حد كبير للتشكيل الفني.

 

 

The objective of this study is to demonstrate the corrosion behavior of dental alloys Co-Cr-Mo, Ni-Cr-Mo and Ti-Al-V in artificial saliva at pH=4 and 37oC enriched with ethyl alcohol at 8% percentage. The linear and cyclic polarizations were investigated by electrochemical measurements. Laser surface modification was achieved for the three dental alloys to improve corrosion resistance. The results show that corrosion resistance of Co-Cr-Mo and Ni-Cr-Mo alloys only were increased after laser treatment due to the fact that laser radiation has caused a smoother surface, in addition to the decrement in corrosion current densities (icorr) for Co-Cr-Mo and Ni-Cr-Mo alloys and the reverse scan in cyclic polarization became in the wider range of

Semantic segmentation is an exciting research topic in medical image analysis because it aims to detect objects in medical images. In recent years, approaches based on deep learning have shown a more reliable performance than traditional approaches in medical image segmentation. The U-Net network is one of the most successful end-to-end convolutional neural networks (CNNs) presented for medical image segmentation. This paper proposes a multiscale Residual Dilated convolution neural network (MSRD-UNet) based on U-Net. MSRD-UNet replaced the traditional convolution block with a novel deeper block that fuses multi-layer features using dilated and residual convolution. In addition, the squeeze and execution attention mechanism (SE) and the s

Stenography is the art of hiding the very presence of communication by embedding secret message into innocuous looking cover document, such as digital image, videos, sound files, and other computer files that contain perceptually irrelevant or redundant information as covers or carriers to hide secret messages.

In this paper, a new Least Significant Bit (LSB) nonsequential embedding technique in wave audio files is introduced. To support the immunity of proposed hiding system, and in order to recover some weak aspect inherent with the pure implementation of stego-systems, some auxiliary processes were suggested and investigated including the use of hidden text jumping process and stream ciphering algorithm. Besides, the suggested

Efforts of evaluating manuscripts have developed into sciences that take interest into the development of authorship movement. Expanding the rules and fundamentals of this scientific process along with the growing use of modern methods and techniques contributed further to its development.
Such a disciplinedemands comprehensive knowledge in various fields to reach the most valid results that help reveal significant aspects of the cultural heritage since such a process is an ethical responsibility .Therefore, the editor has to be patient and honest in correcting mistakes, choosing the most acceptable narration and pinpointing the additions and differences as well as other requirements of serious editing.

 Abstract

In order to determine what type of photovoltaic solar module could best be used in a thermoelectric photovoltaic power generation. Changing in powers due to higher temperatures (25^oC, 35^oC, and 45^oC) have been done for three types of solar modules: monocrystalline , polycrystalline, and copper indium gallium (di) selenide (CIGS). The Prova 200 solar panel analyzer is used for the professional testing of three solar modules at different ambient temperatures; 25^oC, 35^oC, and 45^oC and solar radiation range 100-1000 W/m². Copper indium gallium (di) selenide module   has the lowest power drop (with the average percent

In this article it is proved experimentally that the photon is a particle that has mass and constant wavelength by explaining the effect of refractive index on the wavelength and the natural mass of photon. It is very difficult to measure the mass of photon, a simple and easy process was proposed in this paper to calculate the mass length of photon in vacuum (Y) and in medium (Y*), by measuring the length of laser beam in air (L_air) and in medium (L_med). A new method was postulated to calculate refractive index by using these relations (n = Y*/Y), and (n = L_med / L_air) which supposed a new theory of light.

The Iraqi-Kuwaiti relations represent a great issue for the Arab-Arab relations. This relation is characterized by specificity for the tension since the foundation of the State of Kuwait until late. There are many factors that prevented the fulfillment of the aspiration towards the development of the relations, perhaps the most important of which is the issue of Mubarak Great Port which is a difficult issue as far as the relation between the two states is concerned. One year after Iraq put the cornerstone of the Great Faw Port. This is considered as the most important hurdle in front of constructing the relations with the neighbor Kuwait

Solid waste is considered to be one of the rescuers of pollution in case of     neglecting conditions and procedures relating to specific processes of laws, systems, and contracts requirements in addition to recommendations of organizations concerned with environment issue. The environments auditing groups of intosai have taking into account the environments control by various conference and recommended that the Board of supreme audit have and environments controlling taking into consideration auditing procedures on waste management ,and also offered on evidences for experiences of members of countries in order to exchange their knowledge's and experiments .the definition of solid waste and their resources ,risks ,man
