envelope plays a major role in thermal losses. The loss coefficient generated by the air exchange system, in W/K, is calculated by the following formula [21]: (15) qveq : the equivalent volumetric flow rate of the air, transiting in the volume space (m3/h) 0.34 : the volumic thermal capacity of the air (Wh/m3 K) If one or more flows are not used, its values are zero. (16) qvwind_aer is the aeration air flow rate when windows are used as a hygiene ventilation system (for each room). (17)…

I attend the National 4-H Youth Conference and was selected based on my leadership and citizenship qualities. IAlso in 4-H, I have been on a 4-H executive board seven times since I was nine. Moving on to the area of robotics, I have led my robotics team for three years, and in that time, we have won two excellence awards, two state…

1. Introduction Ekofisk Oil Field is the North Sea’s first giant oil field which was discovered by Philips Petroleum in 1969 and approved for development in 1972. Ekofisk oil field is an oil field in block 2/4 which located at the Norwegian Continental Shelf of the North Sea (Figure 1.1). The total recoverable reserves of Ekofisk Oil field originally were 3, 324.2 million bbl oil, 156.1 bn ccm gas and 14.5 million tonnes of NGL. As of December 2012, the remaining recoverable reserves are…

This lab was conducted to find the key differences between the quantity of heat (q) and ∆H of a substance. Different masses of substances CaCl2 and NH4NO3 were dissolved in water to see how changing mass impacts the q and ∆H of a substance. When the two substances dissolve, they become ions. CaCl2 dissolves in a reaction of: CaCl2 Ca2+aq + 2Cl1-aq while NH4NO3 dissolve in a reaction of: NH4NO3 NH41+aq + NO31-aq . As shown in these reactions, when ionic compounds dissolve in water, they break…

N-substituted-2-aminothiazolo[4,5-b]pyrazine derivatives was developed. The key step in this synthesis strategy is tandem reaction of isothiocyanate terminated resin 2 with o-halo-2-aminopyrazine, affording cyclized 2-aminothiazolo[4,5-b]pyrazine resin 4. To increase the diversity of our library, Suzuki coupling reaction was performed at the position C6. Further functionalization of 2-aminothiazolo[4,5-b]pyrazine core skeleton with various electrophiles such as alkyl halides, acyl chlorides, and…

different release behaviors under different pH conditions. In the first 24 h, the DOX-loaded RSF nanospheres both shown fast release at pH 7.4 and pH 5.0. A sustained release was appeared in 7 days and the release rate of DOX under neutral condition was lower than that in acidic conditions as we had expected. It might be because the solubility…

would know how to be around them and not get hurt. It did not take long, I was hooked! Once I became good at riding, I started to go to local horse shows. I joined a local 4-H Horse club, starting going to 4-H events and within a year I graduated to going to 4-H Horse Shows, which lead me to qualifying for the Virginia 4-H State Horse Show in Lexington, VA. This was the first time I had been to a horse show of this size. There were over 500 horses in the same place with riders ages 10 to 19.…

The general strategy of H&M can be summarized and defined as a will to keep on growing simultaneously with sustaining good profitability. The senior management of the corporation believes that overall performance and profitability as well as the sound relationships with the world is dependant on the way people and environment are affected by H&M’s activity. Environmental policy of H&M contains several major ideas that form the identity of the corporation. Each and every H&M activity is subject…

Ever since I was a little fourth grader at Brookview Elementary, I have been heavily involved with the Boone Progressors 4-H club in Dallas County. I have been an active member of my club by holding offices as part of the leadership team. Over my years in 4-H, I have been our club’s photographer, secretary, vice president and our current president. I have also helped plan our club’s activities and service projects. Some of our service projects have included Meals from the Heartland, Operation…
