A vaccination programme combining a live attenuated Salmonella Typhimurium and an autogenous inactivated Salmonella Enteritidis vaccine confers protection and reduces ovarian colonisation with the Salmonella Enteritidis isolate 7A, PT12

Australian Veterinary Journal, EarlyView.
Salmonella enterica serovar Enteritidis (SE) can colonise chicken ovaries and contaminate eggs, posing a global risk of human gastroenteritis, often linked to raw or undercooked eggs. Control options for SE outbreaks in Australia are limited; autogenous SE vaccines are commonly used, while live attenuated Salmonella Typhimurium (ST) vaccines are ...

Manure, Soil Organic Matter and Fertility

Bulgarian Journal of Soil Science, 2016
Higher content of soil organic matter can greatly reduce the difficulties of a good crop production system. Content of organic matter in the majority of Bulgarian soils is very low which is evident from the results of soil survey and the data from mass chemical soil tests – nearly 60% of studied soils are with humus content lower than 2.5%. The organic

A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

Boreas, EarlyView.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Amendment of Potting Soil With Black Soldier Fly Byproducts Affects Fungus Gnat Development

Entomologia Experimentalis et Applicata, EarlyView.
The study's three experiments were conducted in accordance with the development stages of fungus gnats, with adults emerging from the four treatment substrates and being caught on sticky cards as a common indicator. The treatments were formed from peat‐free potting soil, either pure or supplemented with combinations of byproducts from black soldier fly

Substrate Preference of Black Soldier Fly Larvae Is Influenced by Rearing History

Entomologia Experimentalis et Applicata, EarlyView.
BSF larvae were reared under six different conditions: low, medium, or high larval density and on low, medium, and high‐water feeds to investigate feed choice behaviour. Larvae reared under all six conditions preferred substrate colonised by conspecifics. Low‐water feed caused slower larval growth and development.

Strategic materials and state capacity in Renaissance Italy. The economic policies of ‘Roman saltpetre’ procurement

The Economic History Review, EarlyView.
Abstract Demonstrating the existence of a soaring demand for strategic materials in fifteenth‐century Rome, the article pioneers research in the late medieval trade in saltpetre, the irreplaceable, rare component of gunpowder, indispensable for waging war following the diffusion of artillery technology.

Prediction of organic acid concentration in BRS Capiaçu elephant grass silage

Grassland Science, EarlyView.
Abstract This study aimed to develop prediction models for organic acid concentrations in Capiaçu grass (Pennisetum purpureum Schum) silage, based on fermentation parameters and chemical composition. Data were obtained from an experiment that evaluated BRS (Brazil Seeds) Capiaçu grass silage with the inclusion of dehydrated cashew pseudofruit ...
