Endocrine disrupting effects on the nesting behaviour of male three-spined stickleback Gasterosteus aculeatus L
The analysis of patterns of temporal variability in the nesting behaviour of male threespined stickleback (Gasterosteus aculeatus) exposed to the synthetic oestrogen, 17β-ethinylestradiol, revealed immediate, but transient, treatment-related effects. Gluing frequency and time spent near nest were significantly reduced in exposed fish at the beginning of the experiment. The expression of these behaviours subsequently recovered and there was no effect of treatment on nest building success. The potential causes and implications of these findings are discussed
Mean first passage time analysis reveals rate-limiting steps, parallel pathways and dead ends in a simple model of protein folding
We have analyzed dynamics on the complex free energy landscape of protein
folding in the FOLD-X model, by calculating for each state of the system the
mean first passage time to the folded state. The resulting kinetic map of the
folding process shows that it proceeds in jumps between well-defined, local
free energy minima. Closer analysis of the different local minima allows us to
reveal secondary, parallel pathways as well as dead ends.Comment: 7 page
The utilization of an infrared imaging system as a cooling slot blockage detector in the inspection of a transpiration cooled nozzle
A comprehensive examination of the 8 foot temperature tunnel's transpiration cooled nozzle was completed using an infrared imaging radiometer to locate regions of cooling flow irregularities caused by obstruction of three or more adjacent cooling slots. Restrictions in the cooling flow were found and cataloged. Blockages found were due primarily to the presence of residual phosphoric acid being discharged from some of the cooling slots. This acid was used during construction of the nozzle components and was to have been purged prior to its delivery to the NASA Langley Research Center (LaRC). In addition, a radial displacement of one selection of discs located in the spool piece was inspected and cataloged for future reference. There did not seem to be a serious restriction of flow in this defect, but evidence from the infrared images indicated reduced slot activity within the gouge. The radiometer survey uncovered regions where closer inspection is recommended but did not cover the entire surface area of the three nozzle subsections due to equipment limitations. A list of areas with suspected problems is included in Appendix A
