a) A company buys a batch of goods for NOK. 1 million in the first quarter. Sales are zero. Tax is 22%, and the company's average inventory time is 105 days. What is the result after tax for the 1st quarter? b) A company must give customers a credit period of 15 days. You can assume that you see this above one period of 70 sales days, after which the project is assumed to end. Assume sales are the same every day over the period. Ignore taxes and fees. You can assume a relevant return requirement of 10%. Make assumptions if necessary. How profitable/unprofitable is it for the company to give this credit, versus cash sales? The price is assumed to be the same in both options. c) Is there any connection between the warehouse's inventory turnover rate and outgoing inventory accounts receivable? d) In the Autovison case's solution, labor costs are not included. Could they have been included? Explain. e) Should changes in working capital always add up to zero? Justify your answer

Which of the following is FALSE regarding the use of kinase signaling cascades in RTKs? a. The kinase cascade allows for the rapid amplification of the signal. b. Sequentially phosphorylating multiple kinases helps prevent unintended activation. c. It is difficult to break a phosphate bond, ensuring that the kinases remain active for extended periods. d. The use of multiple kinases can have multiple downstream targets leading to multiple changes.

7. a) The Burgers vortex is defined in cylindrical coordinates $(r, \theta, z)$ through the velocity field $\mathbf{u} = u_r \hat{\mathbf{e}}_r + u_\theta \hat{\mathbf{e}}_\theta + u_z \hat{\mathbf{e}}_z$, whose components are $u_r = -\frac{1}{2} \alpha r$, $u_\theta = \frac{\Gamma}{2\pi r} (1 - e^{-\alpha r^2/4\nu})$, $u_z = \alpha z$, where $\alpha$ and $\Gamma$ are constants. Calculate the convective derivative of this velocity field and determine the vorticity field $\mathbf{\omega} = \nabla \times \mathbf{u}$. Is it an incompressible flow? Hint: Check in the literature the form that the operators curl, divergence and convective derivative take in cylindrical coordinates (see for example the appendices of the books by Currie, Acheson or Davidson).
