Working in a team is a practice as old as the first human relationships, in which we collude with other individuals in order to achieve a common goal, and ultimately share both the success and failures of the operation (Buchanan and Huczynski 2011). However, working in a team is a difficult practice where there are many individuals with different ideas, all of them wanting to implement their own methods to attain that final, common goal. Differences in morals, culture, principles and…

1024 Chickens Europe has turned to Skynet for farming advice. European Union agriculture commissioner Phil Hogan announced last Friday a multi-billion dollar plan to integrate digital sensors in every aspect of crop production to “produce more with less.” For instance, data from satellites could determine how best to apply fertilizers and pesticides, thus improving efficiency and crop yields. This undertaking would have been unthinkable a decade ago. But a new advance - parallel…

In every group, structured or not, the group process has many effects on the overall group. This paper will look at the group processes of our cohort, the interactions between subgroups, and the way that it has affected the overall distance learning cohort. It will look at themes which have played out during our most recent trip to campus, namely subgroups formed, as well as the difference in anxiety levels between the foundation and concentration groups and the behaviors that were…

The recent devastation of South Australia as a result of heavy rainfall and flooding was highlighted on Channel 9 News. The high-stress that is generated by such events can help to identify an individual’s ability to be resilient in the face of adversity. Resilience in psychology refers to the capacity of an individual to endure adverse stress while maintaining a functioning physical and psychological state (Wu et al., 2013). Resilient individuals are able to adapt to stressful triggers and cope…

For this term, Cileena Shakur was our team leader. Overall, she did very well in leading our team to be successful for term 4. She was concerned with both the tasks at hand as well as the relationships with the team members, which takes time and commitment from her part and the rest of the team members (Harris and Sherblom, 2010, p. 228). From the very start, Cileena took charge with getting our Powerpoint setup and making sure that each aspect of our presentation was complete and ready to go…

Particle Deformation and Fragmentation: As compaction force increases, contact area between particles increases, particle deformation starts to occur. Elastic deformation: granules attempt to return to their original shape or form after stress is released. Plastic deformation: granules do not totally recover after stress is released. Fragmentation occurs when compaction force continues to increase Particles fracture, create multiple new surface sites, additional contact points and potential…

Computational Fluid Dynamics Computational fluid dynamics (CFD) is the simulation of fluids in engineering systems using modeling such as mathematical physical problem formulation and numerical methods like discretization methods, solver, numerical parameters and grid generation. Computational fluid dynamics is based on the concept of Reynolds averaging of the unsteady Navier-Stokes equation commonly known as (RANS) which are considered by Leishman to be the most adaptable method for…

Mathematical model Heat and mass transfer properties of counter flow wet cooling tower are obtained through the balance of mass and energy equations. The assumptions made for deriving the governing equations are listed below [14, 15]: • Heat and mass transfer take place only normal to the flow direction. • Heat transfer to the environment through the walls are negligible. • Heat transfer from cooling-tower fan is negligible. • Specific heats of water and dry air are constant. • Heat and mass…

AIM OF THE PRACTICAL The aim of this practical was to investigate the reality or the accuracy of the formula for the resultant force on and the position of the centre of pressure on a vertical rectangular surface. SKETCH OF APPARATUS Counterbalance weight Balance pan(with 20g mass piece) Flat/curved surface(as shown below) Water Beaker Mass pieces(20g each) SUMMARY OF THEORY Hydrostatic force is the force exerted by the…

Tribological behavior of double-glow plasma Zirconium-Yttrium alloying on γ-TiAl Cong Huang, Pingze Zhang*, Dongbo Wei, Xiangfei Wei, Xiaohu Chen and Feng Ding (College of Materials Science and Technology, Nanjing University of Aeronautics and Astronautics, Nanjing 211100, China) * Corresponding author: pzzhang_nuaa@126.com Abstract: A Zr-Y alloyed layer was prepared onto the surface of γ-TiAl using double-glow plasma surface alloying technique (DG technique). The results showed that the Zr-Y…
