This paper represents research on improving the working characteristics of a direct injection 16.5 Hp diesel engine by changing the engine's charging and design method. With the help of SolidWorks 3D software, previous design and rendering plans were compared and evaluated visually compared to the new method.

Performance of a vertical subsurface flow constructed wetland under different operational conditions
The performance of a vertical subsurface flow constructed wetland (VSSFCW) for sewage effluent treatment was studied in an eight month experiment under different operational conditions including: vegetation (the presence or absence of common reeds ‘‘Phragmites australis”), media type (gravel or vermiculite), and mode of sewage feeding (continuous or batch). Plants had a significant effect (P < 0.05) on the removal efficiency and mass removal rate of all pollutants, except phosphorous.

Timolol maleate (TiM), a nonselective b-adrenergic blocker, is a potent highly effective agent for management of hypertension. The drug suffers from extensive first pass effect, resulting in a reduction of oral bioavailability (F%) to 50% and a short elimination half-life of 4 h; parameters necessitating its frequent administration. The current study was therefore, designed to formulate and optimize the transfersomal TiM gel for transdermal delivery.

Dilution of the intake air of the SI engine with the inert gases is one of the emission control techniques like exhaust gas recirculation, water injection into combustion chamber and cyclic variability, without scarifying power output and/or thermal efficiency (TE). This paper investigates the effects of using argon (Ar) gas to mitigate the spark ignition engine intake air to enhance the performance and cut down the emissions mainly nitrogen oxides. The input variables of this study include the compression ratio, stroke length, and engine speed and argon concentration.

Monte-Carlo modeling allows calculating the detector efficiency in gamma spectrometry of environmental samples with taking into consideration both the photon selfabsorption in sample itself and absorption in all other materials between the sample and the detector’s active part. In this paper, the peak efficiencies of the Hp Ge detector (GMX) for gammas at various energies (emitted isotropically from the standard disk source and volumetric source - environmental sample, in which the different radionuclides are present) ...
