The first emerging records of a dragonfly in the dark zone of subterranean ecosystems: Exuviae and newly emerged adults of Hyrcanian Goldenring, Cordulegaster vanbrinkae in Danial Cave, northern Iran. [PDF]
Ecol EvolThe paper is about the first emerging records of an Odonata species in the dark zones of subterranean ecosystems. According to the scientific literature, the records are new for the order Odonata. Also, the study considered some behaviors of Hyrcanian Goldenring, Cordulegaster vanbrinkae in darkness.

KARIZ SU SİSTEMİNİN UYGUR KÜLTÜRÜNDEKİ SOSYOKÜLTÜREL DEĞERİNİN ARAŞTIRILMASI
Uluslararası Uygur Araştırmaları Dergisi, 2023 Doğal kaynaklarn hiçbiri sınırsız değildir. Doğal kaynakları bilinçli şekilde kullanmak, kaynakların ömrünü uzatabilir ve sürdürülebilirliği sağlanabilir. Su kaynağının bilinçsizce kullanılmasından dolayı yer altı tatlı su kaynakları bitmek üzere olup su kıtlığı yaşanmaktadır.

Simulation‐supported characterization of 3D‐printed biodegradable structures
GAMM-Mitteilungen, Volume 44, Issue 4, November 2021., 2021 Abstract In this article, a proof‐of‐concept study is presented, in which in‐situ full‐field deformation measurements via digital image correlation, finite element analysis, and nonlinear optimization techniques are combined to characterize the heterogeneous structural behavior of a bio‐based material 3D‐printed via binder jetting. The special features

Ecology and Evolution, Volume 11, Issue 17, Page 11700-11717, September 2021., 2021 In this study, we investigate the effect of rangewide and local barriers on contemporary genetic differentiation for western populations of white‐crowned sparrows (Zonotrichia leucophrys). Microsatellite markers revealed that habitat influences genetic structure, as individuals found in coniferous ecosystems were genetically distinct from individuals ...

Study on torque and clamping forces of screw‐connected plywood
Engineering Reports, Volume 2, Issue 7, July 2020., 2020 In this brief study, the time‐dependent clamping forces of screw‐connected plywood elements are investigated. The aim is to describe the time‐dependent progression of clamping forces in direct relation to screw torques. Abstract In various engineering applications, screws are commonly used to connect wood and engineered wood products to each other.
