Development and Evaluation of an Environmental Awareness Android Game
Get PDFThe main purpose of this project is to create a game application that will help raise awareness about the environment and environmental issues. The proponents came up with this idea to give players the knowledge of what will happen to the environment if it is taken for granted by humans. PARABUKAS has eight (8) mini-games and some animation videos that the players will enjoy and at the same time, gain knowledgeable information with the trivias/facts that will be provided in the game. PARABUKAS is an offline game and is downloadable online via Google’s Play store. The game was divided into two categories namely, the Quick Game in which the player could choose which of the mini-games to play and the Classic Game which is the normal flow of the game where the mini-games are played randomly. The evaluation instrument used was the user’s Evaluation Sheet for Game Design/Animated Video with the criteria of Game Design, Game Script, Graphic Arts, Music and Sound, Quality, Intellectual Component, and Compliance with Project Objectives. The overall mean was interpreted as “Excellent”. The evaluation result shows that the game application is a tool for learning and increasing awareness
Context-Aware System for Indoor Localization
Get PDFUser location is an important information to provide personalized service in any domain of interest. In this paper, we present a context-aware system to find location of a user at office domain. Hence, smartphone of the user transmits Wi-Fi signal and our system identifies the user by matching MAC address of the smartphone. Wi-Fi signal strength is used to calculate the distance of user from office room. Additionally, PIR sensor value and office time are used to increase localization accuracy as well as minimize the conflict of user location. Raspberry pi 3, a low-cost embedded platform, is used to collect and process sensed information, generate low-level context, and reason user location from available contexts. Demonstration result of our system shows an excellent performance within our domain of interest
Fractal analysis of the mesas within Deuteronilus Mensae region of Mars
Get PDFDeuteronilus Mensae (43.9°N; 337.4°W) is region within the Ismenius Lacus quadrangle, located within the northern hemisphere of Mars. The area is very rich in erosion landforms: flat-top plateaus and butes. The present research investigates the fractal structure of the plateaus (mesas or mensae) within the area. For this purpose using number/area approach a fractal analysis of 90 of these morphostructures was performed. The obtained fractal dimension (FD) of -1.25 is an indicator that the natural processes that created and shaped the topography within this Martian region have the same self-organized and nonlinear nature like those on planet Earth
Bioelectricity from Microbial Fuel Cell Using Wastewater with Carbon/Copper Electrodes
Get PDFThree dual chamber microbial fuel cells (MFCs) labeled MFC-A, MFC-B and MFC-C were fabricated with agar-agar salt bridge as the proton exchange membrane. Each of the MFCs contained wastewater as catholyte. Biochemical and Physiological tests was carried out on the wastewater sample to obtain characteristics which will be helpful in the identification of microbial species in the sample and measure some physiological parameters. Readings of voltage and current with different resistors of 10Ω, 100Ω and 1000Ω and with no resistor was taken for 10 to 12 hours daily for 14 days.
The power density was calculated for the MFCs. Also, the MFC performance was calculated in terms of various parameters such as Biological Oxygen Demand (BOD), Total Dissolved Solids (TDS), pH, Conductivity and Temperature. MFCs A, B and C showed a maximum voltage output of 0.987V, 1.621V and 1.409V respectively. The maximum power densities for MFCs A, B and C were calculated as 0.329W/cm2, 2.56 x 10-5W/cm2 and 0.00197W/cm2 respectively. The BOD removal efficiency of MFCs A, B and C was calculated as 71.70%, 73.35% and 72.00% respectively
Artificial Photosynthesis for Production of Hydrogen Gas for Fuel
Get PDFPhotolysis of water is one of the most reliable methods of producing hydrogen fuel to meet the global demand for clean and cheap energy. Over reliance on fossil fuels and hydro-electricity is unsustainable in the era of depleting resources and climate change. Artificial photosynthesis tries to mimic the natural process of photosynthesis that takes place in plants and some bacteria to produce oxygen gas and hydrogen protons. This review proposes the process of mimicking the plant photosynthesis to produce hydrogen gas for fuel. The extension to photosynthesis generates twice the amount of hydrogen gas compared to the amount of oxygen produced. Among the many advantages of using solar water splitting method, there is zero carbon dioxide emission, sufficient water resources in many parts of the world, plenty of sunlight energy, and renewability. This review paper provides detailed mechanisms of how the photolysis of water can be used to produce hydrogen fuel. The design of the photocatalysts and solar cell, as the photolysis device, has also been discussed in detail.

An organic solvent-free and quick determining method for routine residue monitoring of tetracycline and 4-epi-tetracycline in cow’s milk
Get PDFUnder organic solvent-free conditions, a quick, easy, small-scale sample preparation followed by an isocratic mobile phase HPLC for quantifying tetracycline (TC) and its 4-epimer, 4-epi-tetracycline (4eTC), in cow’s milk was described in this paper. The sample preparation could be made only homogenization using a handheld ultrasonic-homogenizer with deproteining aqueous solution followed by filtration with the disposable unit. For determination and identification of analyte, an Inertsil WP300 C4 and isocratic 100% aqueous mobile with photodiode array detector were used. The method validation data were well within the international analytical method acceptance criteria. The total time required for the analysis of one sample was less than 7 min. In all the process, no organic solvents were used. The present method may be proposed as an international harmonized analytical method for routine residue monitoring of TC and 4eTC in cow’s milk. 
Spectrophotometric Complex formation Study of Murexide with Nickel and Cobalt in Aqueous Solution
Get PDFIn the present study, the formation constant and the stoichiometry of murexide complexes with Co (II) and Ni (II) have been determined spectrophotometrically in aqueous solution at 25oC. Two experimental parameters governed the complex formation, pH and time, have been investigated. The formation and stoichiometry constants have been determined by two methods: Job's and mole ratio's methods. The absorption maxima for Co-murexide and Ni-murexide complexes were: 480, 460 nm, respectively. The two Spectrophotometric methods confirm the formation of 2:1 (M:L) complexes with stability arrange of: Co > Ni. The formation constants (Kf) determined by the Job's method were as follows: 2.06x1014 and 1.21x1011 for Co-murexide and Ni-murexide, respectively. Also, using mole ratio's method, the formation constants were found to be: 9.18x1011 and 6.01x1011. Molar absorptivity values of the studied complexes have also been determined (by Job's and mole ratio's methods) and the average values were: 18235 and 13284 l/mol.cm for Co and Ni, respectively
