Since start studying the subject of this research, I have been busy with several queries; most of them were trying to reach the relation of technical civilization development and its role in the appearance & transformation the modern painting schools. This had been enhanced by checking the artistic works for different times and trying to understand and study the subjects of these paintings and how those works had been done. Did we reach to the result that the great success of the modern techniques had caused intellectual and psychological change inside the artist himself, making him changing his subjects & turning over the roof of his portrait and minimizing the time needed to fulfill the portrait and its ingredients. This can be touchable in many affiants, First of all the disappearance of the functions and traditions of the church and Divinity from the artistic works, changing it over with the nature's elements, then reversion on the nature itself and misshaped it depending on scientific facts based on analyzing and cantoning. Then misshape every thing to reach the absolute abstract. The French revolution came in order to record great developing in ideology and freedom domain through bourgeois state, liberal and democratic values which were the first base of transferring process, then civilization's jump and the followings of the scientific inventions, the appearance of the mutual challenges among the fighting state on advantages and greediness. Above all the arising of fight represented by the First World War & the Second World War then the Cold War, to play basic role in enhancing the technical development - the one we are in now-.The (painters-artist) is result of this civilization, and his art summarizes those big changes, this what we call (modernity) which is an impression represents having the contemporaries to this civilization or getting through these big events and their feelings that they are witnessing an artistic revolution which is collimated to the scientific or political revolution. If we wanted to set a history, boiling eon of specialized in modernity (the eon of total abstract of shapes) which started in 1905 ( by thoughts and Persons like Abulineer, Soundars, Max Jacob, Brack, Picasso, analytic cubical etc...) so it is started before the war 1914 – 1918 and reaches its optimum over the end of this war; but the seeds of this boiling eon started a lot before this stage. So we have to study these seeds which overturn on what is found and bring on something not traditional in paintings which needs blasting off from pioneers who broke the traditional painting roles, which means that the modern painting schools with its revolution called (modernity) started from the portrait of Claude Monet (Impression, Sun Rising) in the second half of the seventeenth century; considering that the ideological and scientific developments had been started two centuries before with the invention of printing machine by the German black smith Gontberg in the middle of fifteenth century. The one who could change the memory of the humanity and was its way to built new memory depending on writing historical record of the nations depended on in its rebirth, and built its scientific & ideological progress. The continuous progress of the sciences and techniques in addition to the works division had been entered to the social life after the continuous changes and collapsing of traditional culture and criteria, then the social division to the work led to a wide political connection and made kind of social conflict that had been witnessed in nineteenth and twentieth centuries. After that the importance of the population growth, the cities centricities, the huge development for information and communication means, had appeared on followings. These factors forgathered had recorded its impression on the modernity concept and made it appeared as a social exercising, and a form of life based on changing and invention which led all the literary and cultural conversions based on wariness, disestablish, and the continuing movement. This was before the First and the Second World War; or it might be the reason for them. . So the researcher fact's become and as it is found in art’s history .the revolution of the shape's abstract reaching to the absolute abstract .(modernity) started from Claude Monet portrait (impression - sun rising), and the development of civilization and techniques allowed what was not accepted in arts in previous ages to become accepted and desired under the sign of trend and developing in two ways in shape and style or concept or modern painting or ((Modernity)).

In the present work, asphaltenes and resins separated from emulsion samples collected from two Iraqi oil wells, Nafut Kana (Nk) and Basrah were used to study the emulsion stability. The effect of oil resins to asphaltene (R/A) ratio, pH of the aqueous phase, addition of paraffinic solvent (n-heptane), aromatic solvent (toluene), and blend of both (heptol) in various proportions on the stability of emulsions had been investigated. The conditions of experiments were specified as an agitation speed of 1000 rpm for 30 minutes, heating at 50 °C, and water content of 30%. The results showed that as the R/A ratio increases, the emulsion will be unstable and the amount of water separated from emulsion increases. It was noticed that the em

A four-stroke, direct injected, single cylinder, diesel engine was tested at constant speed and at different load conditions without coating. Then, the inlet and exhaust valves faces were coated by about 500µm with ceramic materials. Ceramic layers were made of YttriaStabilized Zirconia (YSZ), and NiCrAl as a bond coat. The coating technique adapted in this work is the flame spray method. The engine with valves ceramiccoated research was tested for the same operation conditions of the engine (without coating). The results indicate a reduction in both fuel consumption by about 7.6% and particulate emissions by about (13

Show MoreFaujasite type NaY zeolite catalyst was prepared from locally available kaolin, then the prepared NaY zeolite have been modified by exchanging of sodium ion with ammonium to produce NH4Y zeolite. NH4Y zeolite was converted to HY zeolite by ion exchanging with oxalic acid. Zinc and nickel promoters have been added to the prepared HY zeolite catalyst, and the effect of these promoters on the catalytic activity of the prepared HY catalyst was studied in fluid catalytic cracking process using light gas oil as a feedstock. The experimental results show that the promoted catalyst gives higher gas oil conversion and gasoline yield than HY zeolite catalyst at the same reaction temperature and WHSV. It was also found that the promoted catalyst gi

Therefore, one of effective ways to improve the photomixer emitter performance was using nanodimensions electrodes inside the optical active region of the device. Due to the nanodimension sizes and good electrical conductivity of silver nanowires (Ag-NWs), they have been exploited as THz emitter electrodes. The excited surface plasmon polariton waves (SPPs) on the surface of nanowire enhances the incident excitation signal. Therefore, the photomixer based Ag-NW compared to conventional one significantly exhibits higher THz output signal. In thi

Polystyrene (PS) and Polycarbonate (PC) polymers. The stress – strain curve for pure PS
and pure PC, shows that Young modulus for PS is higher than Young modulus for PC,
because PS have higher ultimate strength than PC.
The addition of TiO2 to PS and PC will reduce the Young modulus and ultimate stress,
because the TiO2 particles will reduces or freeze the orientation of these molecular chain
and reduced the toughness of PC, while when the TiO2 were added to PS, the value of
toughness will be stabilized because TiO2 particles make these chains interlocked and the
mobility of the chains will be restrict.
The CdSe pure films and doping with Cu (0.5, 1.5, 2.5, 4.0wt%) of thickness 0.9μm have been prepared by thermal evaporation technique on glass substrate. Annealing for all the prepared films have been achieved at 523K in vacuum to get good properties of the films. The effect of Cu concentration on some of the electrical properties such as D.C conductivity and Hall effect has been studied.
It has been found that the increase in Cu concentration caused increase in d.c conductivity for pure CdSe 3.75×10-4(Ω.cm)-1 at room temperatures to maximum value of 0.769(Ω.cm)-1 for 4wt%Cu.All films have shown two activation energies, where these value decreases with increasing doping ratio. The maximum value of activation energy was (0.319)eV f
The first studies on shocks and vibrations were carried out at the beginning of the 1930s to improve the behavior of buildings during earthquakes. Vibration tests on aircraft were developed from 1940 to verify the resistance of parts and equipments prior to their first use. Flutter is a well-known example of dynamic aero elasticity, where when oscillation of structure interacted with unsteady aerodynamic forces the flutter will occur. Vibration on any structure without damping means that self-harmonic oscillation will occur, and in most cases the oscillation may start to increase until structural failure. This behavior is very similar to resonance phenomena if only the oscillation is being studied as a vibration case. In vibration suppre

n-Hexane conversion enhancement was studied by adding TCE (Trichloro-ethylene) on feed stream using 0.3%Pt/HY zeolite catalyst. All experiments were achieved at atmospheric pressure and on a continuous laboratory unit with a fixed bed reactor at a temperature range 240-270◦C, LHSV 1-3h-1, H2/nC6 mole ratio 1-4.
By adding 435 ppm of TCE, 49.5 mole% conversion was achieved at LHSV 1h-1, temperature of 270ºC and H2/nC6 mole ratio of 4, while the conversion was 18.3 mol% on the same catalyst without adding TCE at the same conditions. The activation energy decreased from 98.18 for pure Pt/HY zeolite to 82.83 kJ/mole by adding TCE. Beside enhancement the activity, selectivity and product distribution enhanced by providing DMB (Dimethyl b
