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.

 

 

In this work, ZnS thin films have been deposited by developed laser deposition technique on glass substrates at room temperature. After deposition process, the films were annealed at different temperatures (200ºC , 300 ºC and 400ºC ) using thermal furnace.The developed technique was used to obtain homogeneous thin films of ZnS depending on vaporization of this semiconductor material by continuous CO2 laser with a simple fan to ensure obtaining homogeneous films. ZnS thin films were annealed at temperature 200ºC, 300 ºC and 400ºC for (20) minute in vacuum environment. Optical properties of ZnS thin film such as absorbance, transmittance, reflectance, optical band gap, refractive index extinction coefficient and absorption coefficien

In Indonesia, cattle feces (CF) and water hyacinth (WH) plants are abundant but have not been widely revealed. The use of microorganisms as decomposers in the fermentation process has not been widely applied, so researchers are interested in studying further. This study was to evaluate the effect of the combination of CF with WH on composting by applying white-rot fungal (WRF) (Ganoderma sp) microorganism as a decomposer. A number of six types of treatment compared to R₁(ratio of CF:WH)(25%:75%)+WRF; R₂(ratio of CF:WH)(50%:50%)+WRF; R₃(ratio of CF:WH)(75%:25%)+WRF; R₄(ratio of CF:WH)(25%:75%) without WRF; R₅(ratio of CF:WH)(50%:50%) without WRF; R₆(ratio of CF:WH)

Abstract 

In the present study, composites were prepared by Hand lay-up molding. The composites constituents were epoxy resin as a matrix, 6% volume fractions of glass fibers (G.F) as reinforcement and 3%, 6% volume fractions of preparation natural material (Rice Husk Ash, Carrot Powder, and Sawdust) as filler. Studied the erosion wear behavior and coating by natural wastes (Rice Husk Ash) with epoxy resin after erosion. The results showed the non – reinforced epoxy have lower resistance erosion than natural based material composites and the specimen (Epoxy+6%glass fiber+6%RHA) has higher resistance erosion than composites reinforced with carrot powder and sawdust  at 30cm , angle 60

Binary mixtures of three, heavy oil-stocks was subjected to density measurements at temperatures of 30, 35 and 40 °C. and precise data was acquired on the volumetric behavior of these systems. The results are reported in terms of equations for excess specific volumes of mixtures. The heavy oil-stocks used were of good varity, namely 40 stock, 60 stock, and 150 stock. The lightest one is 40 stock with °API gravity 33.69 while 60 stock is a middle type and 150 stock is a heavy one, with °API gravity 27.74 and 23.79 respectively. Temperatures in the range of 30-40 °C have a minor effect on excess volume of heavy oil-stock binary mixture thus, insignificant expansion or shrinkage is observed by increasing the temperature this effect beco

In this research, annealed nanostructured ZnO catalyst water putrefaction system was built using sun light and different wavelength lasers as stimulating light sources to enhance photocatalytic degradation activity of methylene blue (MB) dye as a model based on interfacial charges transfer. The structural, crystallite size, morphological, particle size, optical properties and degradation ability of annealed nanostructured ZnO were characterized by X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM) and UV-VIS Spectrometer, respectively. XRD results demonstrated a pure crystalline hexagonal wurtzite with crystalline size equal to 23 nm. From AFM results, the average particle size was 79.25nm. All MB samples and MB with annealed nanostr

Abstract 

This paper presents an intelligent model reference adaptive control (MRAC) utilizing a self-recurrent wavelet neural network (SRWNN) to control nonlinear systems. The proposed SRWNN is an improved version of a previously reported wavelet neural network (WNN). In particular, this improvement was achieved by adopting two modifications to the original WNN structure. These modifications include, firstly, the utilization of a specific initialization phase to improve the convergence to the optimal weight values, and secondly, the inclusion of self-feedback weights to the wavelons of the wavelet layer. Furthermore, an on-line training procedure was proposed to enhance the control per

The present work involves studying the effect of electrolyte composition [@1= 0.5 wt.%  NH₄F / 5% H₂O / 5% Glycerol (GLY)/ 90%  Ethylene Glycol (EG)] and [ @2= 0.5 wt. % NH₄F / 5% H₂O / 95%  Ethylene Glycol (EG)]  on the structural and photoelectrochemical properties of titania nanotubes arrays (TNTAs). TNTAs substrates were successfully carried out via anodization technique and were carried out in 40 V for one hour in different electrolytes (@1, and @2). The properties of physicochemical of TNTAs were distinguished via an X-ray Diffractometer (XRD), Field Emission Scanning Electron Microscope (FESEM), an Energy Dispersive X-ray (EDX), and UV–visible diffuse reflectance.
