Learning Activity: Diffusion And Osmosis

Inquiry-based learning (IBL) is a student-centered Pedagogic strategy, a process that is ideally led by students. This strategy aims to teach students science by doing it, to attain conceptual change, or accommodate new knowledge, as Jean Piaget’s theory of cognitive development claims. To achieve that, students work collaboratively. Build on previous knowledge and one another’s work engaging in active self-directed learning. Find resources, means, and use tools, based on their own formulated questions, and discover appropriate resolutions to questions and...

Pid Controller Tuning Method In Reverse Osmosis System Using Particle Swarm Optimization Technique

Abstract This Paper describes the tuning of PID (proportional integral and derivative) by using a technique which is generally known as Particle Swarm Optimization. The technique reloves around the iterative method in terms of approach. In Reverse Osmosis System the method is used to adjust the pH level of the water in the system. The Particle Swarm Optimization is used to tune the parameters of PID controller. The purpose is to achieve an optimal solution by reaching to a stable...

The Concept Of Osmosis

The mass of each will be recorded at 24 hours and then again at 48 hours, to provide data for an approximate curve of when osmosis is fastest to when or if the line plateau’s out, indicating that equilibrium has been reached. These curves between each concentration of solution can be compared to create a visual comparison of osmosis. A control was also included in this experiment to eliminate the independent variable in one group of potato cores so the...

Examination Of The Bodily And Enzymatic Processes: Osmosis Transpiration Within The Membrane And Body

With nutrients being consumed daily by individuals, this lab serves to inform one of the processes of osmosis and diffusion when digested, as well as detecting the nutrient that will result in either process. Due to the human viewing the objective, they must be informed of the processes that occur within their bodies, hence the usage of a semi-permeable membrane and substances to determine the process. The processes must be acknowledged as well as the functions of nutrients within the...

Difference Between Osmosis Vs Diffusion

If you’ve been wondering about the difference between osmosis and diffusion for some time then you’re in luck because today we’re going to lift the lid on these two often confused words in an accessible manner that you’ll be able to easily understand. In their base form, both words are actually direct opposites of one another. You’ll soon understand precisely how and why when we delve into the exact definitions of each word in conjunction with providing you with a...

Improvement Of Polyamide Reverse Osmosis Membranes By Coating With Ag/chitosan Nanodispersion Prepared By Gamma Radiation

Abstract Silver/Chitosan nanodispersion (Ag/CS) prepared by gamma ray was used to modify the thin-film composite reverse osmosis (RO) membrane. The silver nitrate solutions were added to the chitosan solution with different concentrations of 5 to 20 (wt/wt %) and exposed to gamma radiation at different irradiation doses. The size of the silver/chitosan nanodispersion is investigated by transmission electron microscopy (TEM). The membranes characterized by FT-IR spectroscopy, scanning electron microscope (SEM) and contact angle measurement. Contact angle measurements showed that the...
