Ryegrass toxicity organism found on other grasses
Yellow slime disease caused by Corynebacterium sp. has recently been found in three grass species.
The diseased grasses were found in the field growing with each other and with affected toxic annual ryegrass
An Agent-Based Model of Heterogeneous Driver Behaviour and Its Impact on Energy Consumption and Costs in Urban Space
By 2020, over 100 countries had expanded electric and plug-in hybrid electric vehicle (EV/PHEV) technologies, with global sales surpassing 7 million units. Governments are adopting cleaner vehicle technologies due to the proven environmental and health implications of internal combustion engine vehicles (ICEVs), as evidenced by the recent COP26 meeting. This article proposes an agent-based model of vehicle activity as a tool for quantifying energy consumption by simulating a fleet of EV/PHEVs within an urban street network at various spatio-temporal resolutions. Driver behaviour plays a significant role in energy consumption; thus, simulating various levels of individual behaviour and enhancing heterogeneity should provide more accurate results of potential energy demand in cities. The study found that (1) energy consumption is lowest when speed limit adherence increases (low variance in behaviour) and is highest when acceleration/deceleration patterns vary (high variance in behaviour); (2) vehicles that travel for shorter distances while abiding by speed limit rules are more energy efficient compared to those that speed and travel for longer; and (3) on average, for tested vehicles, EV/PHEVs were ÂŁ233.13 cheaper to run than ICEVs across all experiment conditions. The difference in the average fuel costs (electricity and petrol) shrinks at the vehicle level as driver behaviour is less varied (more homogeneous). This research should allow policymakers to quantify the demand for energy and subsequent fuel costs in cities

Hyper-precarious lives : Migrants, work and forced labour in the Global North
This paper unpacks the contested inter-connections between neoliberal work and welfare regimes, asylum and immigration controls, and the exploitation of migrant workers. The concept of precarity is explored as a way of understanding intensifying and insecure post-Fordist work in late capitalism. Migrants are centrally implicated in highly precarious work experiences at the bottom end of labour markets in Global North countries, including becoming trapped in forced labour. Building on existing research on the working experiences of migrants in the Global North, the main part of the article considers three questions. First, what is precarity and how does the concept relate to working lives? Second, how might we understand the causes of extreme forms of migrant labour exploitation in precarious lifeworlds? Third, how can we adequately theorize these particular experiences using the conceptual tools of forced labour, slavery, unfreedom and precarity? We use the concept of âhyper-precarityâ alongside notions of a âcontinuum of unfreedomâ as a way of furthering human geographical inquiry into the intersections between various terrains of social action and conceptual debate concerning migrantsâ precarious working experiences

Gendered barriers to educational opportunities: resettlement of Sudanese refugees in Australia
This paper argues that whilst equitable educational pathways are integrated into educational policy discourses in Australia, there are significant gendered barriers to educational participation among members of the Sudanese refugee groups. The specific conditions of forced migration reinforce disadvantage and further limit opportunities. Cultural factors play a key role in this, as the data from this study demonstrate. Participants in this study are Sudanese refugees who arrived in Australia as part of the humanitarian programme. The paper draws upon interviews and focus group data that were collected for a larger study on the broader issue of resettlement of Sudanese refugees in Australia. This paper argues that women from refugee backgrounds are particularly at risk and face cultural and
