FORTRAN 4 program calculates velocities and streamlines in a tandem blade turbomachine

Computer program gives blade-to-blade solution of the two-dimensional, subsonic, compressible, nonviscous flow problem for a circular or straight infinite cascade of tandem or slotted turbomachine blades. The method of solution is based on the stream function using iterative solution of nonlinear finite-difference equations

Computer program for calculating velocities and streamlines on mid-channel flow surface of axial or mixed-flow turbomachine

Program uses finite-difference and stream filament methods, input consists of blade and flow-channel geometry, upstream and downstream flow conditions from hub to shroud, and mass flow. Output includes streamline coordinates, flow angles, and velocities on mid-channel flow surface

FORTRAN program for calculating velocities and streamlines on the hub-shroud mid-channel flow surface of an axial-or mixed-flow turbomachine. 2: Programmer's manual

A FORTRAN-IV computer program, MERIDL, has been developed that obtains a subsonic or shock-free transonic flow solution on the hub-shroud mid-channel flow surface of a turbomachine. The blade row may be fixed or rotating and may be twisted and leaned. Flow may be axial or mixed, up to 45 deg from axial. Upstream and downstream flow variables can vary from hub to shroud, and provision is made to correct for loss of stagnation pressure. The results include velocities, streamlines, and flow angles on the flow surface and approximate blade surface velocities. Subsonic solutions are obtained by a finite-difference stream-function solution. Transonic solutions are obtained by a velocity-gradient method, using information from a finite-difference stream-function solution at a reduced mass flow

Revised FORTRAN program for calculating velocities and streamlines on the hub-shroud midchannel stream surface of an axial-, radial-, or mixed-flow turbomachine or annular duct. 2: Programmer's manual

A FORTRAN IV computer program has been developed that obtains a detailed subsonic or shock free transonic flow solution on the hub-shroud midchannel stream surface of a turbomachine. The blade row may be fixed or rotating, and the blades may be twisted and leaned. Flow may be axial, mixed, or radial. Upstream and downstream flow variables may vary from hub to shroud, and provisions are made to correct for loss of stagnation pressure. The results include velocities, streamlines, and flow angles on the stream surface and approximate blade surface velocities

How to produce clean milk

Although every dairy farmer would like to be the possessor of soundly-constructed dairy premises and a complete set of up to date equipment, many are compelled to use buildings and equipment which fall far short of this ideal. Even with limited facilities however, the production of clean good-quality milk is neither difficult nor impossible, provided that the farmer applies the knowledge of dairy hygiene which is readily available to him

Dynactin-dependent cortical dynein and spherical spindle shape correlate temporally with meiotic spindle rotation in Caenorhabditis elegans.

Oocyte meiotic spindles orient with one pole juxtaposed to the cortex to facilitate extrusion of chromosomes into polar bodies. In Caenorhabditis elegans, these acentriolar spindles initially orient parallel to the cortex and then rotate to the perpendicular orientation. To understand the mechanism of spindle rotation, we characterized events that correlated temporally with rotation, including shortening of the spindle in the pole-to pole axis, which resulted in a nearly spherical spindle at rotation. By analyzing large spindles of polyploid C. elegans and a related nematode species, we found that spindle rotation initiated at a defined spherical shape rather than at a defined spindle length. In addition, dynein accumulated on the cortex just before rotation, and microtubules grew from the spindle with plus ends outward during rotation. Dynactin depletion prevented accumulation of dynein on the cortex and prevented spindle rotation independently of effects on spindle shape. These results support a cortical pulling model in which spindle shape might facilitate rotation because a sphere can rotate without deforming the adjacent elastic cytoplasm. We also present evidence that activation of spindle rotation is promoted by dephosphorylation of the basic domain of p150 dynactin

Ben and Jimmy Podcast

With our podcast, Ben and I were hoping to gain a better understanding of how a college or university impacts the local business of their town. By having a better understanding of this topic Ben and I hoped to find different ways in which we could help these businesses when students are not on campus. In order to find these solutions, we interviewed the local businesses to understand how their business changes when students are not on campus and what they do differently to go about their business. After listening to our podcast, Ben and I hoped people would have a better understanding about how important universities are to local businesses. We hoped our audience would be more willing to shop at local businesses when they are at their universities in order to support them. For the design and structure of our podcast, we envisioned that we would first discuss our purpose for making our podcast, then conduct the interview, and lastly we would debrief the interview answers and discuss their connection to class material and impacts for the future. We followed this layout because we believed that it would flow very well and would create a clear beginning, middle, and end to our podcast which it did. Ben and I worked with members of our local community in order to complete the interview questions and this worked very well. The local bar was willing to answer all of our questions which gave us more insight into the impacts that universities have on their local businesses. The feedback that we received from our peers was very helpful and allowed us to pick up on some of the flaws in our original first podcast. For example, we were only able to hear the audio out of one side of the headphones in our original podcast so for the final podcast we made sure to fix this so you could hear the podcast out of both sides.https://digitalcommons.bucknell.edu/soci258/1010/thumbnail.jp
