Identifying galaxy candidates in WSRT HI imaging of ultra-compact high velocity clouds [PDF]

, 2016
Ultra-compact high velocity clouds (UCHVCs) were identified in the ALFALFA HI survey as potential gas-bearing dark matter halos. Here we present higher resolution neutral hydrogen (HI) observations of twelve UCHVCS with the Westerbork Synthesis Radio ...

Borax Promotes Fertility of Brassica napus Better Than Other Boron Species at Suboptimal Supply

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Continuous and sufficient boron (B) supply is essential for achieving maximum yield in Brassica napus. Increasing incidences of environmental water limitation are linked to reduced plant B availability and increased B deficiencies.

Effects of Biochar and Maize Roots on CO2 Emissions and Microbial Biomass C in Loess Soils

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Refractory substances such as biochar and labile substances such as dead fine and coarse roots play important roles in soil organic matter dynamics and have key ecological functions. However, interactions between these substances have only rarely been studied.

Assessment of selected soil parameters in a long-term Western Canadian organic field experiment [PDF]

, 2007
A long-term field study was used to compare soil nitrogen and phosphorous status, and soil aggregate stability in organic and conventional cropping systems. Two rotations were tested: a grain only and a grain-alfalfa hay rotation.

Botanical treatment enhances biochemical responses in enset (Ensete ventricosum (Welw.) Cheesman) clones

JSFA reports, EarlyView.
Abstract Background Bacterial wilt of enset (Ensete ventricosum (Welw.) Cheesman) is a severe disease caused by Xanthomonas campestris pv. musacearum, resulting in complete crop failure and considerable damage. This study assessed the biochemical responses of two enset clones (one resistant and one susceptible) when inoculated with the pathogen and ...

Rumen methanogenic archaea and their correlation with enteric methane emission in ruminant animals: A systematic review and meta‐analysis

JSFA reports, EarlyView.
Abstract Background Livestock, especially ruminants, are a major source of global methane emissions, primarily produced by methanogenic archaea during enteric fermentation. We performed a systematic review and meta‐analysis to account for factors that could influence the relationship between ruminal methanogenic populations and methane emissions, such ...

Nutrient composition and heavy metal accumulation in water hyacinth [Eichhornia crassipes (Mart.) Solms] and water lettuce (Pistia stratiotes L.) from the Dande River, Nepal: Implications for use as alternative feed resources

JSFA reports, EarlyView.
Abstract Background The proliferation of invasive aquatic macrophytes poses a significant ecological challenge globally, while many tropical regions face chronic shortages of affordable livestock feed. This study addresses this dual problem by assessing two invasive species, water hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes ...
