Hey there! As someone who works in pharmacology research, I can walk you through calculating IC50 in Excel. IC50 represents the concentration where a substance achieves half-maximal inhibition.Here's my step-by-step approach:1. Prepare your data - You'll need concentration values and corresponding response values (usually as percentage inhibition)2. Create a scatter plot with concentration on x-axis and response on y-axis3. Add a trendline - Right-click on data points, choose "Add Trendline," then select "Logistic" or "Sigmoid" fit4. Display equation on chart - This gives you the curve parameters5. Set up calculation - Use the formula = (LOG((50/(100-50)))/-SLOPE) or similar based on your trendline equationThe key is ensuring your data follows a proper sigmoidal curve. I'd recommend checking out this detailed guide from GraphPad which explains the underlying math really well.

Hey there! I graduated from KNUST last year but helped my younger sibling with this just last month. The process has changed a bit since my time.Current steps for iPhone:- Download "KNUST AIM" from App Store (make sure it's the official one)- Username: Your student ID (usually your index number)- Password: If first time, try your index number or your surname in uppercaseIf stuck:1. Check if you've registered your student account online first2. Make sure you've completed the initial student portal registration3. Try resetting your password through the KNUST student portal website firstPro tip: The app works way better on campus WiFi than on mobile data for some reason. If you're off-campus and having issues, try using a VPN or wait until you're on university network.The interface isn't the most intuitive, but once you're in, it's got everything you need for academic management. Good luck with your studies!

I went through this process myself last year for my small retail business, and let me tell you - it's confusing but totally doable!What worked for me was:1. I created a separate bank account in QuickBooks just for the PPP funds (you don't need a real separate bank account, just a QB account)2. Every time I paid payroll or rent, I transferred money from the PPP account to my regular checking and categorized those transfers as "PPP Eligible Expenses"3. When forgiveness came through, I just zeroed out the PPP account and categorized the difference as "Forgiven Debt"The beautiful part of this method? When my accountant asked for documentation, I could just run a report on that PPP account and show exactly where every dollar went. It made the forgiveness application so much easier!Honestly, the hardest part was figuring out which expenses qualified - the rules changed like three times while I was tracking everything!
