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)).
Nano gamma alumina was prepared by double hydrolysis process using aluminum nitrate nano hydrate and sodium aluminate as an aluminum source, hydroxyle poly acid and CTAB (cetyltrimethylammonium bromide) as templates. Different crystallization temperatures (120, 140, 160, and 180) 0C and calcinations temperatures (500, 550, 600, and 650) 0C were applied. All the batches were prepared at PH equals to 9. XRD diffraction technique and infrared Fourier transform spectroscopy were used to investigate the phase formation and the optical properties of the nano gamma alumina. N2 adsorption-desorption (BET) was used to measure the surface area and pore volume of the prepared nano alumina, the particle size and the

Cold atmospheric plasma (CAP) is used widely in medical and biological fields because of non-thermal effected. Direct application of plasma is preferred in medical functions, so, direct application of cold plasma has obtained by the floating electrode dielectric barrier discharge (FE-DBD) system. The purpose of this paper to review the effect of (CAP) on the reproductive hormones (testosterone, LH, E2, progesterone, for male rats. The study appeared that no significant effect on E2 and progesterone hormone for all time of exposure, besides this significant difference in LH hormone (P<0.05) at 15 sec, (P<0.0001) at 30, 90 sec and (P<0.001) at 60 sec of exposure to plasma. Added to that significant difference (P<0.01) at 15, 30, 60 sec and no

The film was heated at various annealing temperature under vacuum (Ta =473, 523 and K). Some of physical properties of prepared films such as structural and optical properties were investigated. The patterns of X-ray diffraction analysis showed that the structure of CdTe powder and all films were polycrystalline and consist of a mixture of cubic and hexagonal phases and preferred orientation at (111) direction.
The optical measurements showed that un annealed and annealed CdTe films had direct energy gap (Eg). The Eg increased with increasing Ta. The refractive index and the real p
The aim of this work is studying the binary system ??'??? Ni?)with two ratios (y=36,80) by using casting method for preparing the samples.Magnetic and Mechanical properties have been studidt different httrea^nttem^rature.All the alloys were found a ferromagnetic behavior and sensitive to the heat treatment. Best properties were found at the heat treatment 1100 C°.A significant different results were found above 1100C° for lower magnetic and mechanical values. This is possibly due to the change on the degree of magnetic moment orders, in which most of the moments are started to remove from coupled ferromagnetically.?

A microbial desalination cell (MDC) is a new approach to bioelectrochemical systems. It provides a more sustainable way to electrical power production, saltwater desalination, and wastewater treatment at the same time. This study examined three operation modes of the MDC: chemical cathode, air cathode, and biocathode MDC, to give clear sight of this system's performance. The experimental work results for these three modes were recorded as power densities generation, saltwater desalination rates, and COD removal percentages. For the chemical cathode MDC, the power density was 96.8 mW/m2, the desalination rate was 84.08 ppm/hr, and the COD removal percentage was 95.94%. The air cathode MDC results were different

In this paper, a harvested prey-predator model involving infectious disease in prey is considered. The existence, uniqueness and boundedness of the solution are discussed. The stability analysis of all possible equilibrium points are carried out. The persistence conditions of the system are established. The behavior of the system is simulated and bifurcation diagrams are obtained for different parameters. The results show that the existence of disease and harvesting can give rise to multiple attractors, including chaos, with variations in critical parameters.
Given the paucity and toxicity of available drugs for leishmaniasis, coupled with the advent of drug resistance, the discovery of new therapies for this neglected tropical disease is recognised as being of the utmost urgency. As such antimicrobial peptides (AMPs) have been proposed as promising compounds against the causative Leishmania species, insect vector-borne protozoan parasites. Here the AMP temporins A, B and 1Sa have been synthesised and screened for activity against Leishmania mexicana insect stage promastigotes and mammalian stage amastigotes, a significant cause of human cutaneous disease. In contrast to previous studies with other species the activity of these AMPs against L. mexicana amastigotes was low. This suggests that ama
