The effects of increasing sun light irradiaiton time (60 min, 120 min, 180 and 240 min), increasing photocatalytic power (40 W, 80 W and 120 W), increasing graphene oxide/strontium carbonate (GO/SrCO3) nanocomposites (NCs) concentrations (1 mg/l, 5 and 10 mg/l) on the destructions of four hydrophobic polycyclic aromatic hydrocarbons (PAHs) in a real petrochemical industry wastewater (PCI ww) in Izmir (Turkey) were investigated. The yields in more hydrophobic PAHs with high benzene rings [benzo[a]pyrene (BaP) and benzo[k]fluoranthene (BkF)] were as high as the less hydrophobic PAHs with lower benzene rings [acenaphthylene (ACL) and carbazole (CRB)] at pH=7.0, at 22oC after 240 min sun light irradiation time. The characteristics of the synthesized nanoparticles (NPs) were assessed using X-Ray.......

Soft material robot (Soft Robotics) is a type of gripper with mainly silicon material, Soft Robotics uses a special principle to be able to precisely control the "grab" and "drop" states. Besides, with the nature of soft materials, it has many advantages compared to traditional grippers such as: Good elasticity, durability, easy to replace, no damage. gripper deformation. Soft Robotics is increasingly popular even in industrial or civil industries because of the novelty of the product. In the robotic system, the soft material consists of two parts: the air supply system and the actuator. This paper describes the principle as well as the method to build a research on the actuator part of the soft material robot.

This study aimed to determine the effect of budget quality on the effectiveness of budget execution at the Harbor Master Division Class II Office of Tulehu and to determine the effect of knowledge regarding budgeting as a moderating variable on the relationship between influential budget quality and effectiveness of budget execution at the Harbor Master Division Class II Office of Tulehu. This research used the associative method. Based on the study's results, budget quality had a significant and positive effect on the effectiveness of budget execution, and knowledge of budgets could not moderate the relationship between budget quality and budget execution effectiveness at the Harbor Master Division Class II of Tulehu.

As an essential part of automatic generation control, load-frequency control (LFC) strategy in a large-scale electric power grid aims to maintain network frequency at a nominal value (50Hz or 60Hz) against load changes. It is a fact that the whole power network in a nation consists of many sub-power plants which are connected via transmission lines or tie-lines, making control schemes to stabilize the network more challenging. One of the most crucial control schemes in such a power interconnection is the LFC, which is built up to bring the network back to the stability after time-by-time continuous and random load variations. It is clear applying conventional LFC regulators e.g........

Major reasons for air pollution are carbon emission from industries, which is responsible for 70% of the total air pollution. Carbon storage and capture are in great demand for the mitigation of the emissions. The method which is trending is carbon storage in microbes such as algae cells and fungi. There is a lot of research in reusing the stored carbon to manufacture into many products. One of them is manufacturing color dyes using various formulation techniques which are complex and skilled chemical engineers are needed. This paper gives detailed information on microbial fermentation, anaerobic digestion.........
