To produce Zinc Oxide NanoParticles, ZnO-NPs, different methods can be used. However, the utilization of Liquid-Phase Pulsed Laser Ablation, LP-PLA, methodology of three distinct environment of aqueous using pure zinc plate will be one of the approaches for this job. Thus, in this work, concentrates on the influence of the results after employing some changes on the environment in other words, the influence of the NPs size and/or the NPs availability/appearance. Cetyltrimethylammonium Bromide, CTAB, is one of the three surfactants that have been used in the water-based solution. That is, the Sodium Dodecyl Sulfate, SDS, besides the Distilled Water, DW, the three surfactants will be ready when the molarity of the DW is around 10− 3 M. The specifications of the employed laser are: 800 nm as a wavelength, radiating with pulses of 130 fs as a duration, which will be repeated every 1ms (1 kHz). That is, with these laser settings, the femtosecond Ti: Sapphire laser was generated to irradiate the zinc target, which attain ablation inside the aforementioned solution. Hence, according to the sort of the surfactant that has been employed in the experiment, different shades were introduced in the resultant solutions, this reveals that the NPs are appeared with various dimensions. The shadow that has been captured is the white color which ranges from foggy to milky. Note that in the experiment was utilized the UV-VIS spectroscopy test in order to evaluate and characterize the ZnO-NPs that were produced. The creation of discrete sizes of ZnO-NP was verified by the surface plasmon resonance (SPR) spectra, which displayed separate absorbance peaks. For instance, the CTAB surfactant was at 207 nm, for the SDS, it was at 212 nm, while for the DW environment, it was at 218 nm. Accordingly, it was found, using the Scanning Electron Microscopy, SEM, captured images of the created nanoparticles, that the CTAB surfactant introduces the most regular/small sizes with respect to that produced using the SDS, which gives uneven sizes and shapes. Furthermore, the NPs generated in DW formed agglomerations with diameters in the micro range and exhibited a combination of spherical and hexagonal forms. The production of ZnO-NPs was confirmed using Fourier Transform Infrared Spectroscopy (FTIR) analysis, which demonstrated absorption readings in the 435–445 cm− 1 range.
An experimental study is conducted on the utilization of the inlet ethanol injection technique in order to evaluate its impact on the performance of a two-shaft T200D mini-gas turbine engine. The maximum degradation recorded in power output was 32.8% at the climate temperature of 45oC. Nevertheless, at that temperature, adding ethanol with Eth/LPG ratio of 20% by volume brought an enhancement in power output of 19.2% compared to normal LPG run. SFC of the dual-fuel engine ranked a level of 22% higher than that with pure LPG consumption. The overall efficiency suffered a maximum reduction of 14.4% with Eth/LPG fuel ratio of 20%, but when the loading was raised beyond 70% of the engine full load; the efficiency of dual-fuel engi

Fiscal policy is one of the important economic tools that affect economic development in general and human development in particular through its tools (public revenues, public expenditures, and the general budget).
It was hoped that the effects of fiscal policy during the study period (2004-2007) will positively reflect on human development indicators (health, education, income) by raising these indicators on the ground. After 2003, public revenues in Iraq increased due to increased revenues. However, despite this increase in public budgets, the actual impact on human development and its indicators was not equivalent to this increase in financial revenues.
