vocabulary concepts and symbols were memorized in these weeks. Of all these topics the most important concept I learned in this class was number theory and set notation. The most difficult skills for me throughout the class were anything involving fractions. All of these concepts learned throughout the 9 weeks are relevant to the characteristics of a professional math teacher. This course has helped me develop my own understandings and ideas to bring fourth to my own class. Of all of the concepts

RG was used as the low cetane blending component to retard the combustion phasing. Other influential parameters‚ such as air/fuel ratio‚ EGR‚ and intake temperature‚ were maintained constant. The experimental results show that increasing the RG fraction retards the combustion phasing to a more optimized value causing indicated power and fuel conversion efficiency to increase. RG reduced the first stage of heat

Preparation of the propolis extracts: the propolis sample of the Brazilian native bee species Melipona quadrifasciata was obtained in May‚ 2013 in the city of Blumenau‚ SC‚ Brazil (26 ° 54’21.3 "S 49 ° 04’49.1 "W). In order to obtain a hydroalcoholic crude extract (HCE)‚ 284.3 grams of propolis were pulverized and macerated in 70% ethanol (m m-1)‚ left in a dark chamber for 7 days at room temperature‚ filtered in vacuum and taken to complete drying in a rotary evaporator with reduced pressure.

determine the following: (a) The fractions of total ferrite and cementite phase. (b) The fractions of the proeutectoid ferrite and pearlite. (c) The fraction of eutectoid ferrite. (a) This part of the problem is solved by application of the lever rule employing a tie line that extends all the way across the α + Fe3C phase field. Noting that the alloy composition is 99.65 wt% Fe – 0.35 wt% C‚ i.e. carbon concentration in the alloy‚ CO‚ is 0.35 wt%‚ the weight fraction of ferrite (α) is given as:
