The effect of Carica papaya (pawpaw) leaf extract as an organic 'green' inhibitor on mild steel corrosion in 1M HClsolution was studied at ambient conditions. The biochemical species responsible for corrosion inhibition of the extract were determined both qualitatively and quantitatively by standard phytochemical methods. The species detected were alkaloids (1.93%), flavonoids (0.22%), saponins (19.74%), and tannins (3.82%). Six experimental setups were used, for the corrosion inhibition studies namely;distilled water (control 1),1M HCl (control 2), 5ml, 10ml, 15ml and 20ml extract in 1M HCl respectively. Weight loss technique of corrosion rate measurement was used for the experimental work...............

Exploitation of M.endeavouri shrimp by net fishing gear is suspected to improve gradually marked with increased production in the last three years. Overfishing can threaten its sustainability. The purpose of this study is to examine biological aspects such as catch composition, catch distribution, size structure, first caught size (L50%), infinity length (L∞), sex ratio, gonad maturity level (GML), growth properties , and condition factors. In addition, made the concept of M.endeavouri shrimp fisheries resource management was made. The method used in sampling is the survey method with systematic random sampling. Shrimp samples are taken proportionally which is about 10% of the total catch. The results showed that the first size was caught (L50%) 25.5 mm carapace length. The length of infinity (L∞) of M.endeavouris shrimp is about 44.74 mm. Comparison of male and female sex ratios 1,1: 1...........

Liquefied Petroleum Gas (LPG) is a major source of cooking energy in Nigeria today, especially in the city areas because of its clean energy compare to firewood and charcoals used in the rural areas. There is always a danger of gas leakage as a result of negligence or failure from the regulating valve of the gas cylinder which poses great danger to the inhabitants of those houses, due to highly flammable nature of cooking gas. Cases of gas related fire has been on the rise and this can be avoided by employing a technology. In this work, a gas leakage detector system is proposed. The system is designed using microcontroller 8051, MQ-6 sensor, resistors, transistors, transformer, buzzer etc...............

Ecologic footprint is a tool that is numerically expressing the negative impacts we have on earth and guiding us to make positive changes on our behaviours and attitudes towards the environment. Keeping in mind that achievements and awareness gained during university years can kick-start a lifelong change, this study has been conducted to get the faculty of engineering students of a university located in south-eastern Turkey to measure ecologic footprint and carbon footprint. The study took place during the 2018‐2019 academic year, involving 141 engineering students who have been subjected to individual Ecologic Footprint Survey. The survey provided general briefing to each participant about ecologic footprint and carbon footprint and suggestions have been made with regards to methods of reducing individual footprint. At the end of the study, the ecologic footprint and carbon footprint changes of the faculty of engineering students have been assessed, on the basis of their department, gender, age and the number of individuals in their families.

Keywords - Ecologic footprint, carbon footprint, ecologic awareness, sustainable life.

Irrigation is done to ensure availability of water for plant growth. Traditional irrigation methods are not very efficient and require human operator for there day-to-day operations. Automatic irrigation systems are more efficient and less dependent on human operators and are therefore cheaper on the long run. Different approaches at developing automatic irrigation system have been reported with their different advantages and disadvantages.In this paper, a smart irrigation system which has capacity to remotely monitor essential farm variables such as soil moisture, and remotely operate the irrigation equipment is developed. Experimental tests on the developed system show that it is effective and could be adapted easily for practical use.

Keywords - Smart, Soil moisture, Plant growth, Automatic, Human operator.

Wawonii Island is one of the small islands in Southeast Sulawesi Province whose entire region represents one Regency in Southeast Sulawesi, namely Konawe Kepulauan Regency. The people of Wawonii Island are people who are more likely to choose to live farming and use existing forest resources than being fishermen, whereas generally they live in coastal areas. This is supported by the fact that Wawonii Island holds a large amount of potential, especially the potential of forest resources which if managed wisely will be able to provide welfare for people living around the forest, especially swidden agriculture who cultivate forest land with local wisdom that can ensure the sustainability of forest ecosystems also means sustainability human life on the island. In fact, existing forests have suffered a lot of damage due to exploitation for the sake of clearing land for plantations and mining and the occurrence of illegal logging by a number of irresponsible individuals..............

To achieve precise springback prediction, it is important to describe correctly stress and strain state during the forming process and after the load removal. The accuracy of the springback prediction depends on the material model, which describes the deformation behavior of steel sheets. In each sheet metal forming process, the steel, in this case deep drawing quality steel DC06 exhibits springback effect, which is governed by strain recovery of material after the load removal. In this work, numerical simulation of a V-shape part bending was performed and compared with experimental data. Springback is related to many parameters like forming conditions, tool geometry and material properties such as sheet thickness, yield stress, work hardening, strain rate sensitivity and elasticity modulus............

There have beensignificant technologies improvements since the oil industry first began drilling horizontal wells. However, the greatest obstacle is identifying suitable technology that can be used successfully in a specific reservoir. Selecting the best technology is a complicated process that requires simulation techniques combined with dynamic performance. Dynamic performance is modeled using numerical techniques, which can become an arduous task. This leads to an increase in well productivity or injectivity which surpasses the capabilities of vertical wells. This paper reviews studies that have used a number of different simulation techniques to accurately model horizontal wells. These techniques have been used to model different aspects of the recovery process, including completion, simulation, production, and enhanced oil recovery. These techniques can be used to solve complex problems with minimum costs in money and time.

Keywords - Local grid refinement;Applied simulation techniques for horizontal wells.
