Mechanisms affecting the overturning response in global warming simulations [PDF]

, 2005
Climate models used to produce global warming scenarios exhibit widely diverging responses of the thermohaline circulation (THC). To investigate the mechanisms responsible for this variability, a regional Atlantic Ocean model driven with forcing ...

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

Advanced Functional Materials, EarlyView.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

Analysis of Differences in Productivity, Profitability and Soil Fertility Between Organic and Conventional Cropping Systems in the Tropics and Sub-tropics

Journal of Integrative Agriculture, 2014
Organic farming aims to stimulate soil fertility by avoiding the use of synthetic fertiliser inputs, relying instead on locally available natural resources.

Investigating Crude Sesame Oil Sedimentation and Its Monitoring Using Laser Backscattering Imaging (LBI)

Applied Sciences, 2023
Sesame oil is a food and energy resource that is not used enough. Sedimentation of crude oil after pressing can remove particles and happens regardless of the producer’s intention.

Sources of variations in total column carbon dioxide [PDF]

, 2011
Observations of gradients in the total CO_2 column, (CO2), are expected to provide improved constraints on surface fluxes of CO_2. Here we use a general circulation model with a variety of prescribed carbon fluxes to investigate how variations in ...

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields

Advanced Science, EarlyView.
Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

Osteomalacia in subtropical Auckland

BMJ Case Reports, 2019
A 56-year-old man was referred with left-sided hip pain. MRI scans demonstrated an undisplaced stress fracture in the femoral neck and subchondral oedema within the femoral head. Bone densitometry showed T-scores of −2.0 at the spine, −3.5 at the femoral neck and −2.4 for the total hip. Laboratory tests revealed 25-hydroxyvitamin D <10 nmol/L.

An Analysis of Tropical Transport: Influence of the Quasi-biennial Oscillation [PDF]

, 1997
An analysis of over 4 years of Upper Atmosphere Research Satellite (UARS) measurements of CH4, HF, O3, and zonal wind are used to study the influence of the quasi-biennial oscillation (QBO) on constituent transport in the tropics.

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

Advanced Science, EarlyView.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

Discovery of the first lichenized fungus in the family Chaetothyriaceae ( Ascomycota ), Ceramothyrium ryukyuense sp. nov.

Plant and Fungal Systematics
Ceramothyrium ryukyuense ( Chaetothyriaceae ) is described as a new species from Okinawa, southern Japan. It is characterized by subglobose minute ascomata (up to 110 μm diam.) covered with a brown mycelial pellicle, small ellipsoid 1(–2)-septate ...
