Dystopian texts often present an exaggerated vision of the world that is vastly different to reality, mostly as the consequence of certain human responses and actions in the past or current society, thus adding to the shocking aspects of the text. Literature of the dystopia genre also challenge preconceptions about the world and the human identity, thus provoking further contemplation about what it means to be human. Kazuo Ishiguro's dystopian novel Never Let Me Go (2005) demonstrates that…
What is the difference between reproductive cloning and therapeutic cloning and what are the ethical issues associated with it?
Cloning occurs naturally in nature. We can see this in some plants and single celled organisms, like bacteria, which produce genetically identical offspring through asexual reproduction. Ideas of artificial cloning have been around since 1938 when Hans Spermann proposed his "fantastic experiment" to grow an embryo from an egg with a nucleus obtained from another cell.…
fluid flow with in the process chambers largely governs the outcome. Thus research on double diffusive convection flows in relations to various applications in many mechanical and chemical engineering industries and also in fields like oceanography, nuclear technology, renewable energy etc [1-6] became admirable. The research reported in context to double diffusive convection are as flows: Coasta et al.  studied the double diffusive convection in a cavity filled with moist air , they…
There are many definitions of thermal comfort, which depends on the aims and expectations of those who defined it (Chappells, and Shove, 2004). Jiao (2010) stated that, the rate at which human body gain and lose energy, and also the state of comfort is satisfactory once all heat flow in and out of the body are in equilibrium. Also, (ASHRAE 2004), described it as “the state of mind that expresses satisfaction with the surrounding environment.” This definition highlights subjective and…
How Does Temperature (thermal kinetic energy) Affect the Phases of Matter?
Can matter be in anything that elements can mix to something different?
Why does matter have to have more than 2 elements?
What things do not have matter?
Why does matter have to have more of, weight, volume or density?
Why is there such things called matter?
Why is the earth made of matter?
How much does matter influence the earth and what it does to help?
What is matter?
cup when you place your hand to the side of it. Radiant energy transfer is caused by a warm surface giving up its heat to a cooler surface. Whenever there is a temperature difference between two surfaces, both surfaces will attempt to equalize. Radiant energy travels through space without heating the space itself. It only turns into heat when it contacts a cooler surface. Our human comfort relies just as much on radiant heat transfer as it does on air temperature, yet the majority of heating and…
The rate of heat transfer in the evaporator is calculated using equations 10 and 11
Q_in=(εC)_evap (T_(in,evap)-T_evap ) (10)
Where ε is the effectiveness of the evaporator, C is the capacitance rate for the air or chilled water passing through the evaporator. Tevap is the temperature of refrigerant in evaporator and Tin, evap is the temperature of the air or chilled water at the inlet of the evaporator.
Equation 11 express Qin in terms of enthalpy.
Q_in=m ̇_ref (h_4-h_1)…
Case Study 1:
1.The most likely cause of the ABO typing discrepancy in the reverse type is due to “unexpected antibodies” such as a cold/room temperature reacting alloantibody.
2.Since the auto control didn’t agglutinate, an alloantibody is suspected. With that being said, it needs to be one that reacts at room temperature. Furthermore, based on the antigen typing of the patient P1 is suspected to be interfering with the ABO results. The Lewis antigen was ruled out due to it being present on…
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…
The objectives of the experiment are:
• Measurement of creep deformation in 2 materials; lead and polypropylene at room temperature.
• Determine how creep deformation of chosen materials can be affected by stress.
• Recognise that the two classes of materials show differences in creep behaviour.
• Awareness of creep as a design consideration.
Structural materials are often placed in service under a certain applied load at elevated temperatures (eg. wind…
