meaning to drive. Propulsion means to push forward or drive an object forward. A propulsion system produces thrust to push an object forward. It is the study of how to design an engine that will provide the thrust that is needed for a plane to take off and fly through the air. Most spacecraft today are propelled by forcing a gas from the back/rear of the vehicle at very high speed through a supersonic nozzle. This sort of engine is called a rocket engine. Liquid fuel propulsion systems use a fuel

bio gas Co-digestion of Biomass for Methane Production: Recent Research Achievements Wei Wu ABSTRACT Anaerobic digestion (AD) is a process by which microorganisms break down biodegradable material in the absence of oxygen. Anaerobic digestion can be used to treat various organic wastes and recover bio-energy in the form of biogas‚ which consists mainly of CH4 and CO2. A great option for improving yields of anaerobic digestion of solid wastes is the co-digestion of multiple substrates. Numerous

Engineering Marine Propulsion Marine propulsion in modern marine engineering is a flourishing technology. There are many ways to generate thrust in order to move a ship (or boat) through the water. These types of marine propulsion systems available vary from the archaic steam engines to reciprocating diesel engines. With the technology burst in the last decade‚ engineers have focused on creating efficient‚ economical‚ and environmentally friendly propulsion systems. This essay will explore the

for foods to travel through the digestive tract? • How does digestion occur in each of the following parts of the digestive system? o Mouth o Stomach o Small intestine o Large intestine Note. Include descriptions of other organs or components of the digestive system. • How do proteins‚ fats‚ and carbohydrates break down in the digestive system? • What types of food help with digestion? When a human sees or smells food the salivary glands are the first

Does the PH level of acids in our stomach affect the digestion proteins? Yes‚ if the acidity in my/a stomach is high in terms of the PH balance then the proteins in our stomach will be digested faster because acids are known to breakdown and eat away at many objects. The purpose of this project was to observe how the digestion of protein varies at different pH levels. This project in my eyes helps society by finding the best types of food (i.e. ones with higher/ lower acidity and pH balance)

Digestion Self-design Practical: The effect of pH on enzyme activity Rationale Amylase is an enzyme involved in the digestion system which catalyses the breakdown of starch into sugars. It is not only present in human saliva but also in the pancreas‚ where it hydrolyses dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. pH has an effect on the activity of all enzymes‚ including amylase. As the pH level increases
