Plant Direct, Volume 10, Issue 8, August 2026.ABSTRACT Dhurrin, a cyanogenic glucoside, plays an important role in Sorghum bicolor physiology and defense. The concentration of dhurrin in sorghum is influenced by both nitrogen status and stage of plant organ development. While nitrogen resupply activates the expression of genes for dhurrin biosynthesis, the molecular mechanisms underlying this ...

Thinking through payment in fieldwork
American Ethnologist, Volume 53, Issue 3, Page 236-248, August 2026.Abstract Ethnographic research has long illuminated diverse economic relations. Yet ethnographers have said little about an economic relation that they themselves often rely on: payment in fieldwork. Indeed, the particularities of monetary exchange between ethnographers and their interlocutors often remain hidden—or taboo.

Acta Ophthalmologica, Volume 104, Issue 5, Page 544-550, August 2026.Abstract Purpose To compare retinal vessel oxygen saturations and diameters before, 1 and 3 months after trabeculectomy. Methods Retinal oxygen saturations and vessel diameters were obtained using retinal oximetry. The effect of the postoperative intraocular pressure (IOP) decrease on the arteriovenous difference (AV‐difference) was evaluated ...

Weathering above the tides: how iceberg-roll-generated waves shape Arctic rocky shores
Polar ResearchA significant limitation of the current understanding of cold coast evolution is the paucity of field observations on the development of rocky coasts in glaciated parts of the Arctic.

PERFORMANCE PREDICTION OF CHAIN SAW MACHINES USING SCHMIDT HAMMER HARDNESS
Bilimsel Madencilik Dergisi, 2018 Schmidt hammer hardness (RL) provides a quick and inexpensive measure of surface hardness that is widely used for estimating the mechanical properties of rock material such as strength, sawability, cuttability and drillability. In this study, RL as predictors, which is thought to be a useful, simple and inexpensive test particularly for ...
