Capillary Effect 3. Self Perpetual motion 1. Fluid mechanics Fluid mechanics is related to the fluids that are in motion and forces acting on them. Fluid mechanics has two branches fluid statics and fluid dynamics. In Fluid Mechanics we actually observe fluid motion and calculation of the…

Coulter Counter Method. Schematic Diagram Diagram 1: The basic setup of coulter counter method. Test tube containing conducting fluid placed in the beaker containing same conducting fluid. Orifice in the test tube connect the circuit. Electrodes are placed in beaker and test tube and voltage is applied. Vacuum is applied in the test tube to allow fluid movement from beaker to test tube. Counting circuit will calculate the amount of particle and pulse height analyser will measure the particle…

COMPARATIVE STUDY ON FRICTION WELDED AND ELECTRON BEAM WELDED JOINTS MADE BY 20VNiMoCr120 STEEL Gabriela IANCULESCU*, Lucia Violeta MELNIC, Marian Andrei GURĂU Ovidius University of Constanta Abstract: In the paper there are presented experimental results concerning mechanical characteristics of friction-welded joints in comparison with electron beam welded joints, made by 20VNiMoCr120 heat-resistant steel, which are part of some elements working at high pressure and temperature. The paper…

I observed an Alcoholics Anonymous (AA) group in Paterson, NJ, which is a self-help group that helps alcoholics in the recovery and treatment phase. It’s an open group for anyone who wants to change their drinking habits. They have the meeting every Friday at 7:30 pm. There’s no specific qualifications to attend this group. No age limit, specific race, or education is required to become a member. The program is free for any individual who wants to stop their alcohol assumptions. The group’s main…

Samuel Gladding (2008) in his book provides a comprehensive view of groups throughout the lifespan. The groups looked at are; groups for children, groups for adolescents, groups for adults and groups for older adults. Gladding considers group to be an important aspect throughout the lifespan. Group work with children is looked at by Gladding (2008) as “work with children under the age of 14 that requires a special knowledge of child development and group theory” (p. 245). Consequently, when…

1- Summary This study is based on the analysis of pressure distribution around a NACA 23015 airfoil section with a flap of length equal to the 30% of the cord at different angles of incidence and flap settings. The experiment was performed in a non –return wind tunnel at a Reynolds number of 4.4×〖10〗^5 and at a Mach number of 0.073. It is of note that increasing incidence will increase lift produced until the critical angle of attack, where the airfoil stalls; moreover, deploying a flap will…

The blast wave generating device developed for this project consists of two sections that are equivalent in cross sectional area to the expansion section channel of the shock tube; the front section has internal damper blades that rotate from a vertical position to a horizontal position, and the rear section is equipped with internal flow straighteners. The device is to be placed in series between the expansion section and the expansion section channel, and bolted together with the flanges of…

Group Observation and Reaction Paper: Kids Incorporated In-Service Meeting In this essay I will give my reactions to a group meeting that I attended using the Group Work Theory. I will focus on the small sub group that was formed that I observed. For that I will review the strengths of the leader of the meeting, skills that were used in the group setting, and what stage I felt the group was in. I will also cover cultural and ethical issues that occurred in the meeting. Finally, I will review the…

information regarding the opportunities above, it has allowed room to continue in taking the next step towards my career in health promotion. Question 1: When looking at the group project, I think there were a few areas that I succeed in as far as group dynamics. When it comes to working within a group setting, organization, responsibility, and a dedicated strong work ethic are…

As the semester draws to a close, I reluctantly write my final paper for my favorite class of my first ever semester here at George Mason University. For this paper I will discus how my peers and I worked together through out the Deliberative Dialogue project. I’m going to use the Tuckman Model of Group Development because I believe I saw my group transition through these stages more prominently. The Forming Stage, or Stage #1, began the day we got our group assignments and were allowed to get…
