Health Problems of Clarinetists: An Epidemiologic Survey

Poster presenting results of a study that characterizes clarinet specific health problems such as site-specific pain, non-musculoskeletal issues, performance anxiety, and related variables including instrument type, use of neck-strap, educational attainment, musician identity, and other lifestyle and performance-related factors. An online survey specifically for clarinetists was developed using techniques adopted from a recent study of trombonists (interactive body maps, skip logic, etc.). In addition to clarinetists being underrepresented in previous epidemiologic research, previous studies did not consider the lower lip as being a potential pain site despite clarinet pedagogues mentioning this concern, proliferation of commercial products to help clarinetists manage lip pain, and the lip being a primary contact point between the instrument and the body. Consistent with findings from Thrasher and Chesky, clarinetists in this study also reported musculoskeletal problems in the right wrist area.

On the evolving nature of c/a ratio in a hexagonal close-packed epsilon martensite phase in transformative high entropy alloys (open access)

On the evolving nature of c/a ratio in a hexagonal close-packed epsilon martensite phase in transformative high entropy alloys

Article studying c/a ratio and transformation volume change of h.c.p. (hexagonal close packed) epsilon martensite phase in transformative high entropy alloys (HEAs) quantified as functions of alloy chemistry, friction stir processing and tensile deformation. The study reveals that while intrinsic c/a is dependent on alloying elements, c/a of epsilon in transformative HEAs changes with processing and deformation.

A novel nano-particle strengthened titanium alloy with exceptional specific strength (open access)

A novel nano-particle strengthened titanium alloy with exceptional specific strength

This article microstructurally tailors an exceptionally high-strength titanium alloy, Ti-6Al-2Sn-4Zr-6Mo (Ti6246) through friction stir processing (FSP) in order to provide enhanced weight savings and improved fuel efficiency. The specific strength attained in one of the conditions is close to 450 MPa m³/mg, which is about 22% to 85% greater than any commercially available metallic material. This novel nano particle strengthened Ti alloy is a potential replacement for many structural alloys, enabling significant weight reduction opportunities.

Physical and optical properties of the International Simple Glass (open access)

Physical and optical properties of the International Simple Glass

This article presents physical property data (both published and previously unpublished) on a single batch of International Simple Glass (ISG), which was cast into individual ingots that were distributed to the collaborators. Properties from the atomic scale to the macroscale, including composition and elemental impurities, phase purity, density, thermal properties, mechanical properties, optical and vibrational properties, and the results of molecular dynamics simulations are presented, as well as information on the surface composition and morphology after polishing. Although the existing literature on the alteration of ISG is not extensively reviewed here, the results of well-controlled static alteration experiments are presented here as a point of reference for other performance investigations.

Effect of MS222 on Hemostasis in Zebrafish

Article studying the effect of MS222 on hemostasis in Zebrafish. The authors performed various assays and find that Hct values, the amount of blood collected, bleeding, and coagulation differ significantly between anesthetized and nonanesthetized fish. These results suggest that blood collected after MS222 anesthesia of zebrafish has altered hemostasis.

Combining loss of function of FOLYLPOLYGLUTAMATE SYNTHETASE1 and CAFFEOYL-COA 3-O-METHYLTRANSFERASE1 for lignin reduction and improved saccharification efficiency in Arabidopsis thaliana (open access)

Combining loss of function of FOLYLPOLYGLUTAMATE SYNTHETASE1 and CAFFEOYL-COA 3-O-METHYLTRANSFERASE1 for lignin reduction and improved saccharification efficiency in Arabidopsis thaliana

This article tests if lignin content can be further reduced by combining genetic mutations in C1 metabolism and the lignin biosynthetic pathway by generating and functionally characterizing fpgs1ccoaomt1 double mutants. The observations demonstrate that additional reduction in lignin content and improved sugar release can be achieved by simultaneous downregulation of a gene in the C1 (FPGS1) and lignin biosynthetic (CCOAOMT) pathways.

LBD29-Involved Auxin Signaling Represses NAC Master Regulators and Fiber Wall Biosynthesis (open access)

LBD29-Involved Auxin Signaling Represses NAC Master Regulators and Fiber Wall Biosynthesis

This article uses a large-scale mutant screening to identify a dominant activation-tagging mutant, fiberless-d (fls-d), showing defective SCW development in stem fibers, similar to that of the nac secondary wall thickening promoting factor1-1 (nst1-1)nst3-3 double mutant. The results demonstrate auxin is upstream of LBD29 in repressing NAC master regulators, and therefore sheds new light on the regulation of SCW biosynthesis in Arabidopsis.

Victims of "adaptation": climate change, sacred mountains, and perverse resilience (open access)

Victims of "adaptation": climate change, sacred mountains, and perverse resilience

This article proposes the concept of "perverse adaptation", where one actor or institution's adaptation to climate change in fact produces aftershocks and secondary impacts upon other groups. Drawing on ethnographic and sociolinguistic research in northern Arizona regarding artificial snowmaking at a ski resort on a sacred mountain, the author elucidates resort supporters' and others' attempts to frame snowmaking as a sustainable adaptation to drought (and, implicitly, climate change) while counterpoising these framings with narratives from local activists as well as Diné (Navajo) individuals.
