Polycyclic Aromatic Hydrocarbons in Soil and Vegetation of Niger Delta, Nigeria: Ecological Risk Assessment

open access: yesJournal of Toxicology, 2023
The Niger Delta, Nigeria, is noted for crude oil exploration. Whereas there seems to be a handful of data on soil polycyclic aromatic hydrocarbon (PAH) levels in this area, there is a paucity of studies that have evaluated soil and vegetation PAHs ...

Remembering Independence, Debating the Nation: Ghana's National Days

open access: yesNations and Nationalism, EarlyView.
ABSTRACT In Ghana, Independence Day is the most important national day and has been annually observed since the attainment of independence in 1957. Additional national days that various military governments introduced to commemorate their ascension to power have been rather short‐lived. Other holidays like Republic Day or Founder's Day have been longer

Control of macrophytes by grass carp (ctenopharyngodon idella) in a Waikato drain, New Zealand [PDF]

open access: yes, 2003
Hornwort (Ceratophyllum demersum L.) and other aquatic macrophytes have historically been mechanically removed from the Rangiriri drain and Churchill East drain to maintain drain efficiency.

Influence of supplementing Guinea grass with differently processed African yam bean on gas production and in vitro digestibility

open access: yesRevista Brasileira de Zootecnia, 2020
This study evaluated the potential utilisation of African yam bean (AYB) seed as a supplement to Guinea grass on in vitro gas and methane (CH4) production, as well as the effect of processing on AYB nutritive value.

VEGETATIVE DEVELOPMENT AND GROWING DEGREE-DAYS OF TROPICAL AND WINTER FORAGES [PDF]

open access: yesEngenharia Agrícola, 2019
One of the limitations to producing irrigated forages is setting suitable biometric parameters to establish the entrance of animals to grazing areas. Such parameters can be measured or even estimated.

The Grammar of Perception: A Case Study of Guambiano (Namtrik) and Duna

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Although the senses provide a common basis for our experience of the world, cross‐linguistic research has revealed substantial diversity across languages in how perceptual experiences are encoded in words. Such variability is also present at the level of grammatical structure, though the project of charting the parameters and limits of cross ...

Effect of sward height on the fermentability coefficient and chemical composition of Guinea grass silage

open access: yes, 2018
There is a high correlation between sward height and pasture sward structure. Therefore, in tropical grasslands, taking sward height into account has been a much better strategy in rotational stocking management than considering pre-defined days of ...

Crop coefficients of tropical forage crops, single cropped and overseeded with black oat and ryegrass

open access: yesScientia Agricola
: Crop coefficient (Kc) is the ratio between crop evapotranspiration (ETc) and reference evapotranspiration (ETo), representing the phenological effects on crop water consumption. Kc is fundamental to estimating ETc by agrometeorological methods.

Anatomical and functional mapping of vagal nociceptive sensory nerve subsets innervating the mouse lower airways by intersectional genetics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We used an intersectional approach with recombinase‐expressing mice and adeno‐associated virus to map and modulate distinct nociceptive afferents in the vagal ganglia. TRPV1+P2X2+ neurons resided in the nodose ganglion (N), innervated the lungs (many projected into the alveoli) but not the trachea, and projected to the nucleus ...

Integrative simulation analysis of myocardial ischaemia–reperfusion injury

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A comprehensive mathematical model of ventricular myocyte was developed to gain insights into the mechanisms underlying cardiac ischaemia–reperfusion injury. The model integrates excitation–contraction (E–C) coupling, cytosolic and mitochondrial pH regulation, pH dependence of major E–C coupling components and cellular energy ...
