Thermal transformation of nitrogen in a subtropical mixed oak forest of Manipur, Northeast India

open access: yesDiscover Soil
The thermal transformations of nitrogen and other soil parameters were studied during October 2007-September 2008 in a control (CL) and burnt (BT) forest sites of a subtropical forest of Manipur, Northeast India dominated by Quercus serrata and Schima ...

Effects on nodular extracts of Alnus glutinosa (l.) Gaertn. on ammonification, nitrification and CO2 production in different soils [PDF]

open access: yes, 1994
The effect of root nodule extracts from European alder (Alnus glutinosa [L.] Gaertn.) on the rates of amrnonification, nitrification and C02 production was evaluated in three soils of different physico-chemical characteristics. The extracts decreased net

Inhibition factor of ammonification in stored urine with fecal contamination

open access: yesWater Science and Technology, 2008
Inhibition factors of urea hydrolysis caused by fecal contamination as source of urease were investigated. The urea hydrolysis was described by initial ammonification rate (IAR). Three factors for the inhibition (pH, free ammonia nitrogen (FAN) and salinity) were investigated in this study. It was found that the optimum pH value for the urea hydrolysis

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment

open access: yesAging and Cancer, EarlyView.
Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.

Logging and forest decline effects on the surface humus horizons in the Šumava Mts.

open access: yesJournal of Forest Science, 2006
Holorganic layers belong among the key ecosystem components of forest soils at higher altitudes. Increased biological activity of the surface humus is very often observed after forest decline and/or forest cut and removal at these sites.

Invasive Andropogon gayanus (gamba grass) is an ecosystem transformer of nitrogen relations in Australian savanna [PDF]

open access: yes, 2009
The African grass Andropogon gayanus Kunth. is invading Australian savannas, altering their ecological and biogeochemical function. To assess impacts on nitrogen (N) cycling, we quantified litter decomposition and N dynamics of grass litter in native ...

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

open access: yesAdvanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

open access: yesAdvanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Microbial functional guilds and genes are key to explaining soil nutrient cycling alongside soil and plant variables

open access: yesEcosphere
Microbes play central roles in soil nutrient cycling; yet, a limited range of microbial community characteristics have been used to explain ecosystem nutrient cycling rates, and their importance relative to plant and abiotic factors remains unclear.
