Age‐Related and Seasonal Variation in Malaria and Other Causes of Fever and Their Association With Clinical Outcomes in Southern Angola: A Hospital‐Based Study

open access: yesTropical Medicine &International Health, Volume 31, Issue 9, Page 1273-1283, September 2026.
ABSTRACT Background Acute febrile illnesses in sub‐Saharan Africa are often attributed to malaria, yet many patients test negative for malaria parasites. The aetiology of nonmalarial fevers remains understudied. Here, we examine likely causes of febrile illnesses and their association with poor clinical outcomes in Angola.

High‐Shear Mixing of Softwood Kraft Lignin in Aqueous Sodium Lignosulfonate: Stable Suspensions, Efficient Emulsification and Controlled Curing of Epoxy Adhesives

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Blending sodium lignosulfonate with softwood kraft lignin generates stable, high‐consistency aqueous suspensions. The lignosulfonate efficiently coats and disperses the kraft lignin particles, producing a thick, extrudable paste. This fully bio‐based, solvent‐free approach demonstrates great potential as a sustainable wood adhesive, paving the way for ...

Pinus armandii ectomycorrhizas mobilize aluminium‐bound phosphorus via carboxylates along a subtropical altitudinal gradient

open access: yesJournal of Ecology, Volume 114, Issue 8, August 2026.
Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

Effect of Low Temperatures on the Block Shear Strength of Norway Spruce Glulam Joints

open access: yesBioResources, 2016
The block shear strength of Norway spruce (Picea abies (L.) Karst.) glulam joints was tested under low temperatures. Glulam samples were glued with the three of the most common outdoor structural adhesives. The cold temperatures tested were 20, −20, −30,
