Contrasting effects of ammonium and nitrate addition on soil organic carbon in Zoige Plateau peatland

Peatland soils, typically nitrogen (N)-limited, are important carbon (C) reservoirs and may be significantly affected by N deposition. Nitrate (NO 3 − -N) and ammonium (NH 4 + -N) are the primary forms of N deposition, with substantial spatial variability. However, how these N fo...

Association Between Anthropogenic Noise and the Spatial Distribution of Feral Rock Doves (Columba livia) in Githurai, Kiambu County, Kenya

AbstractBackground: Urbanization drastically alters natural soundscapes, introducing widespread anthropogenic noise that influences wildlife behavior and habitat selection. Feral rock doves (Columba livia) are highly successful urban exploiters, yet the specific impacts of locali...

Transcritical CO₂ refrigeration cycle modifications: thermodynamic performance, practical challenges and future directions

Carbon dioxide (CO₂, R744) has emerged as a leading natural refrigerant alternative owing to its negligible ozone depletion potential, unity global warming potential, chemical stability, and favourable heat transfer characteristics. However, the low critical temperature (31.1 °C)...

Crop genotypic richness enhances biomass production and phosphorus acquisition in maize‐mycorrhiza symbiosis

Societal Impact Statement: Our study tests how soil and plant biodiversity can enhance sustainability of crop production in Kenya. We tested whether mixtures of maize varieties performed better than monocultures and tested their response to arbuscular mycorrhizal fungi. Mycorrhiz...

Can Organic Amendments Override Environmental Filtering of Soil Microbiomes? Evidence From 20 Years Old Agricultural Field Trials in Contrasting Tropical Sites

ABSTRACT Soil microbial communities underpin ecosystem functions critical for sustainable agriculture, yet our understanding of how long‐term management of tropical agroecosystems shapes these communities remains limited. This is particularly the case in sub‐Saharan Africa where...

The Wilhelmina Ψ Field: A ContinuumTheory of Phase Noise in CoupledResonator Networks

Phase noise limits performance in radar, 5G communications, satellite navigation, and precision timing systems. Existing theory treats phase noise at a single isolated oscillator (Leeson, 1966) or between two coupled oscillators (Adler, 1946; Kurokawa, 1973). No continuous field...

QUALIFIED EMPIRICISM: Science Honoured Within Its Domain

Abstract The relationship between empirical science and theological knowledge has been framed predominantly through two inadequate paradigms: conflict models that subordinate one to the other, and independence models that isolate them into incommensurable domains. Both fail to ac...

ILLUMINATION: THE HOLY SPIRIT'S WORK IN UNDERSTANDING

Abstract This paper articulates the pneumatological dimension of knowing within MKS®-Thronaxis, the Metadisciplinary Knowledge System. While previous publications in the MKS corpus have established Revelation (Axis I) as ontological ground and Inspiration (Axis II) as the divinel...

THE AUTHORITY OF SCRIPTURE: Norma Normans in MKS™-Thronaxis
