Molecular study of lipids in humic acids by sequential chemical degradation [PDF]
, 2009 Lipidy v půdě vykazují poměrně vysokou resistenci k biodegradaci, mohou proto tak zajistit informace o zdrojích organické hmoty a diagenetických procesech. Půdní organická hmota je vysoce heterogenní a vyskytují se v ní různé dynamické systémy.

Mastoid Surgery Does Not Normalize Tympanometric Middle Ear Pressure in Children With Cholesteatoma
The Laryngoscope, EarlyView.Conflicting mechanism‐based hypotheses have been used to promote selection of different approaches to management of the mastoid in order to optimize middle ear pressure homeostasis after removal of cholesteatoma. For example: (a) conservation of mastoid mucosa and opening of ventilation pathways endoscopically to normalize function, (b) removal of ...

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates
Land Degradation &Development, EarlyView.ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Land Degradation &Development, EarlyView.ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...
