All the Juicy Pastures: Greville Texidor and New Zealand

If you type the name Greville Texidor into a Wikipedia search bar, you may be asked if you mean instead ‘grevillea teodor’. Alternatively, you’ll be redirected to biographical websites for Maurice Duggan, one of postwar New Zealand’s most famous short story writers, or Kendrick Smithyman, editor of Greville Texidor’s volume of selected fiction, In Fifteen Minutes You Can Say a Lot. To learn anything about Greville Texidor herself, you need to read All the Juicy Pastures: Greville Texidor and New Zealand, by Wellington-based writer Margot Schwass. Beautifully written, deeply researched, richly illustrated, this critical biography addresses the question of why we should care about the career of a woman writer born in England in 1902, who died by her own hand in Australia in 1964, and who in her lifetime published only seven short stories, a post- Spanish Civil War novella called These Dark Glasses, a few translations of Lorca poems, and a smattering of other non-fiction pieces. Schwass also tackles the question of why we should care about Greville Texidor as a New Zealand writer

Prioritizing Multiple Uses on Public Lands After Bear Lodge

This Article analyzes the courts’ application of First Amendment jurisprudence to Native American cultural activities on federal land. The author concludes that the courts’ use of existing First Amendment law has been strained, especially with respect to Native American cultural practices on federal land. The Article analyzes Bear Lodge Multiple Use Association v. Babbitt within this context to conclude that First Amend­ment jurisprudence may not be the most appropriate legal construct for determining whether to allow or protect Native American cultural activities on federal land. Instead, the Article suggests that Native American practices are often best considered cultural, rather than religious, and as such, a First Amend­ment analysis, which has not been particularly favorable to Native American interests, would not apply. Applying a cultural lens to Native American practices, the Article concludes that federal land managers act well within their prescribed authority when they protect such activities

Reconstructed spatial resolution and contrast recovery with Bayesian penalized likelihood reconstruction (Q.Clear) for FDG-PET compared to time-of-flight (TOF) with point spread function (PSF)

BACKGROUND: Bayesian penalized likelihood reconstruction for PET (e.g., GE Q.Clear) aims at improving convergence of lesion activity while ensuring sufficient signal-to-noise ratio (SNR). This study evaluated reconstructed spatial resolution, maximum/peak contrast recovery (CRmax/CRpeak) and SNR of Q.Clear compared to time-of-flight (TOF) OSEM with and without point spread function (PSF) modeling. METHODS: The NEMA IEC Body phantom was scanned five times (3 min scan duration, 30 min between scans, background, 1.5-3.9 kBq/ml F18) with a GE Discovery MI PET/CT (3-ring detector) with spheres filled with 8-, 4-, or 2-fold the background activity concentration (SBR 8:1, 4:1, 2:1). Reconstruction included Q.Clear (beta, 150/300/450), "PSF+TOF4/16" (iterations, 4; subsets, 16; in-plane filter, 2.0 mm), "OSEM+TOF4/16" (identical parameters), "PSF+TOF2/17" (2 it, 17 ss, 2.0 mm filter), "OSEM+TOF2/17" (identical), "PSF+TOF4/8" (4 it, 8 ss, 6.4 mm), and "OSEM+TOF2/8" (2 it, 8 ss, 6.4 mm). Spatial resolution was derived from 3D sphere activity profiles. RC as (sphere activity concentration [AC]/true AC). SNR as (background mean AC/background AC standard deviation). RESULTS: Spatial resolution of Q.Clear150 was significantly better than all conventional algorithms at SBR 8:1 and 4:1 (Wilcoxon, each p < 0.05). At SBR 4:1 and 2:1, the spatial resolution of Q.Clear300/450 was similar or inferior to PSF+TOF4/16 and OSEM+TOF4/16. Small sphere CRpeak generally underestimated true AC, and it was similar for Q.Clear150/300/450 as with PSF+TOF4/16 or PSF+TOF2/17 (i.e., relative differences < 10%). Q.Clear provided similar or higher CRpeak as OSEM+TOF4/16 and OSEM+TOF2/17 resulting in a consistently better tradeoff between CRpeak and SNR with Q.Clear. Compared to PSF+TOF4/8/OSEM+TOF2/8, Q.Clear150/300/450 showed lower SNR but higher CRpeak. CONCLUSIONS: Q.Clear consistently improved reconstructed spatial resolution at high and medium SBR compared to PSF+TOF and OSEM+TOF, but only with beta = 150. However, this is at the cost of inferior SNR with Q.Clear150 compared to Q.Clear300/450 and PSF+TOF4/16/PSF+TOF2/17 while CRpeak for the small spheres did not improve considerably. This suggests that Q.Clear300/450 may be advantageous for the 3-ring detector configuration because the tradeoff between CR and SNR with Q.Clear300/450 was superior to PSF+TOF4/16, OSEM+TOF4/16, and OSEM+TOF2/17. However, it requires validation by systematic evaluation in patients at different activity and acquisition protocols

Determination of Corresponding Temperature Distribution within CFRP during Laser Cutting

AbstractLaser cutting of carbon fiber reinforced plastics as a thermal process results in a thermal load on the material. Due to the high thermal conductivity of carbon fibers, residual heat is conducted along the fibers, away from the laser interaction zone. Common temperature measurement techniques, such as pyrometry and infrared thermography only allow for observation of the temperature development on the surface of the material. In order to achieve information about the temperature distribution within the material during the cutting process, thermochromes and thermocouples were implemented during the laminating process of CFRP. The cutting tests were performed with a single mode fiber laser emitting a continuous wave and at a wavelength of λ = 1080 nm
