Some effects of thermal-cycle-induced deformation in rocket thrust chambers [PDF]
The deformation process observed in the hot gas side wall of rocket combustion chambers was investigaged for three different liner materials. Five thrust chambers were cycled to failure by using hydrogen and oxygen as propellants at a chamber pressure of

Integrating the In‐Laws: Class and Kin Support Within Marriage in Urban Kenya
Journal of Marriage and Family, Volume 88, Issue 3, Page 777-790, June 2026.ABSTRACT Objective This study compares affinal kin relationships in low‐income and higher‐income families in Nairobi, Kenya. Background In most studies of kinship structure and relationships in sub‐Saharan Africa, culture serves as the basis upon which norms and expectations of kin are differentiated.

Clinical Case Reports, Volume 14, Issue 5, May 2026.ABSTRACT This report describes the first documented case of a two‐port laparoscopic ovariectomy (lapOVE) in a raccoon (Procyon lotor (Linnaeus, 1758)). A rescued, eight‐month‐old, 5.0 kg female raccoon, kept as a pet, was presented to the Veterinarium, clinic of Agricultural University of Georgia (Tbilisi, Georgia), for elective ovariectomy.

Effect of Pre-strain and Pre-corrosion on Ratcheting Behavior of ASTM A668 Class D Steel [PDF]
, 2016 Ratcheting can be considered as one of the serious problems as this phenomenon causes premature failure of structural components. Ratcheting deformation can be regarded as the stress controlled low cycle fatigue (LCF) response of a material which occurs ...

Target Capture Sequencing Provides Insights Into Hybridogenetic Water Frogs
Ecology and Evolution, Volume 16, Issue 5, May 2026.The genomics of European frogs of the genus Pelophylax are intriguing due to their propensity to hybridise, the prevalence of polyploidy, and the unusual hemiclonal hybridogenetic complexes formed in many populations. This study examines the use of target capture sequencing using the Frog Cap bait set to investigate these complex systems.

The cultural psychology of obesity: diffusion of pathological norms from Western to East Asian societies [PDF]
, 2007 We examine the accelerating worldwide obesity epidemic using a mathematical model relating a cognitive hypothalamic-pituitary-adrenal axis tuned by embedding cultural context to a signal of chronic, structured, psychosocial threat.

Bioenergetic trophic trade‐offs determine mass‐dependent extinction thresholds across the Cenozoic
Ecology, Volume 107, Issue 5, May 2026.Abstract Body size constrains trophic interactions, shaping the feasibility of species' populations. Over macroevolutionary timescales, these constraints feed back to shape selection on body size and diet. We develop a bioenergetic, three‐level trophic framework—typical of terrestrial mammalian ecosystems—to explore how bioenergetic trade‐offs emerging
