Ivermectin use on pastured livestock in Colombia: parasite resistance and impacts on the dung community

Revista Colombiana de Ciencias Pecuarias, 2022
Ivermectin (IVM) has been the most widely used antiparasitic agent in veterinary medicine since it came to the market in 1981. In its risk assessment, the American Food and Drug Administration (FDA) determined that, although it is very toxic to aquatic ...

Molecular composition of particulate matter emissions from dung and brushwood burning household cookstoves in Haryana, India [PDF]

, 2018
Emissions of airborne particles from biomass burning are a significant source of black carbon (BC) and brown carbon (BrC) in rural areas of developing countries where biomass is the predominant energy source for cooking and heating.

Crohn's disease and related inflammatory diseases: from many single hypotheses to one "superhypothesis"

Veterinární Medicína, 2014
The aetiology of Crohn's disease and paratuberculosis are the subjects of intensive study and also frequently, of dispute. However, a number of other nosological entities have a similar history, namely type 1 diabetes, multiple sclerosis, sarcoidosis ...

The interactive effects of fertiliser nitrogen with dung and urine on nitrous oxide emissions in grassland

Irish Journal of Agricultural and Food Research, 2016
Nitrous oxide (N2O) is an important and potent greenhouse gas (GHG). Although application of nitrogen (N) fertiliser is a feature of many grazing systems, limited data is available on N2O emissions in grassland as a result of the interaction between ...

Determination of clenbuterol with differential pulse anodic stripping voltammetry technique at tungsten disulfide-modified electrode

Tạp chí Khoa học Đại học Huế: Khoa học Tự nhiên, 2022
In the present work, tungsten disulfide was synthesised and characterised by using X-ray diffraction and scanning electron microscopy. This material was employed to modify a glassy-carbon electrode to analyse clenbuterol.

Improving and disaggregating N2O emission factors for ruminant excreta on temperate pasture soils [PDF]

, 2016
pre-printCattle excreta deposited on grazed grasslands are a major source of the greenhouse gas (GHG) nitrous oxide (N2O). Currently, many countries use the IPCC default emission factor (EF) of 2% to estimate excreta-derived N2O emissions.

Dung Beetle Assemblages Attracted to Cow and Horse Dung: The Importance of Mouthpart Traits, Body Size, and Nesting Behavior in the Community Assembly Process

Life, 2021
Dung beetles use excrement for feeding and reproductive purposes. Although they use a range of dung types, there have been several reports of dung beetles showing a preference for certain feces.

Gaussian lower bounds for the density via Malliavin calculus [PDF]

, 2019
In this paper, based on a known formula, we use a simple idea to get a new representation for the density of Malliavin differentiable random variables.
