In general, the tooth profile of a rack may be curved, and the profile angle \(\phi^\rm A_r\) would then vary from one point of the tooth to another. We now consider a particular rack, in which the teeth are straight-sided. This is the basic rack which we use to define the tooth shape of an involute gear. The profile angle for this rack is constant, and the value of the constant will be represented by the symbol Φr, which is called the pressure angle of the basic rack. Thus, for the basic rack used to define involute tooth profiles,

CM-SRP-01 panel is a standalone product as well as a component in the LudgerTag DMB sialic acid release and labelling kit (LT-KDMB-A1). This kit and the panel can assist you in performing sialic acid analysis which is a regulatory requirement to monitor the level and types of sialic acids during all stages of biopharmaceutical realisation.
Handling: Allow the unopened vial to reach ambient temperature and tap unopened on a solid surface to ensure that most of the lyophilized material is at the bottom of the vial. Gently remove the cap, add the desired volume of reconstitution medium, re-cap and mix thoroughly to bring all the oligosaccharide into solution. For maximal recovery of oligosaccharide, ensure that the cap lining is also rinsed and centrifuge the reconstituted vial briefly before use. Ensure that any glass, plasticware or solvents used are free of glycosidases and environmental carbohydrates. Minimise exposure to elevated temperatures or extremes of pH. High temperatures and low pH will cause desialylation. High pH will cause epimerisation of the reducing terminus GlcNAc.
N2 - This paper revisits the optimal thickness profile problem of a single cooling fin using a one-dimensional heat conduction equation with a convection boundary condition. Firstly, in contrast to previous works, we apply an approach using optimality conditions based on requiring stationarity of the Lagrangian functional of the optimisation problem. This yields an optimality condition basis for the commonly touted constant temperature gradient condition. Secondly, we seek to minimise the base temperature for a prescribed thermal power, rather than maximising the heat transfer rate for a constant base temperature as previous works. The optimal solution is shown to be fully equivalent for the two, which may seem obvious but to our knowledge has not been shown directly before. Lastly, it is shown that optimal cooling fins have a Biot number of 1, exhibiting perfect balance between conductive and convective resistances.

The Rising Senior Edition is the Summer Supplement to the Step Up to College Guide. The Supplement informs juniors entering their senior year about the steps they need to take during the summer to prepare for the college admissions process.
Step Up to College: A Guide to the College Preparation, Application, Admissions, and Financial Aid Processes is annually published and tailored to students in grades 9 to 12 and their families, leading them through each stage of the college admissions process. In addition to the Guide, Step Up to College offers an array of other resources including the Summer Supplement and videos.
In addition to the digital copy, which can be found here, more than 35,000 copies of Step Up to College will be distributed this year to public, public charter, and parochial high schools, branches of the Free Library of Philadelphia, government offices, and many community-based organizations. Request copies of the Guide by filling out this form.
Step Up to College resources are made available through the generous support of many sponsors. The following institutions and organizations have demonstrated their commitment to this important publication and the high school students of Philadelphia by supporting the 34th edition of the Guide:
Supporting Step Up to College is a meaningful way to partner with Heights Philadelphia and support its effort to provide high school students with the tools and resources they need to pursue a college degree. Step Up to College offers funders tremendous outreach opportunities to the Philadelphia community and beyond, and exposure to a large audience of students and their families. College and university supporters are featured in our college profile section and have the opportunity to promote their institution through written text and campus photos.
In honor of the 30th anniversary, this Step Up to College video series, highlighting the key principles of the Guide and the elements of the college application and college-bound process, launched. Topics include:
Back in 2014, we launched the first series of the Step Up to College videos. These three videos are approximately 30 minutes long and cover the topics of Preparing for College, Understanding College Fit, and Applying to College. The new SUTC videos, starring collegians who have navigated the college-going process, are offered in shorter segments, ranging from one to four minutes, and provide the opportunity to learn each segment of the Guide in smaller increments to ensure a better understanding and an easier way to share these important tips with other students on social media.
