Plant essential oils are widely acknowledged for their insecticidal activities and synergistic interaction with conventional insecticides, but their insecticidal modes of action and the mechanism of synergy remain less understood. In this study, electrophysiological screenings on the larval central nervous system (CNS) of the common fruit fly, Drosophila melanogaster, and the housefly, Musca domes
For the indoor and outdoor pest controls, various types of insecticide formulations are available including aerosols, sprays, electric vaporizers, mosquito coils, and traps. In the present study, the insecticidal activity of aerosols, the most commonly used formulation of household insecticides for mosquito control, against Aedes albopictus (Skuse) was assessed using seven commercial products and
Owing to the complexity in the chemical composition of plant essential oils, they often display enhanced insecticidal activity when applied as a mixture. Although the insecticidal activity of plant essential oils has been gaining more attention recently, understanding in the mechanism of synergy has not been studied as much. In the present study, insecticidal activity of 28 individual essential oi
This book challenges the prevailing notion of stability, cohesiveness, and uniformity within Christian communities, inviting readers to view contestation and disagreement as integral to theological reflection and church identity. While the volume focuses predominantly on the Roman Catholic Church as a case study, various chapters broaden the exploration across other Christian and non-Christian tr
Biodegradable plastic mulch films are increasingly adopted in agriculture, yet the ecotoxicological risks arising from their degradation products in mixtures with concurrent chemical inputs remain largely unexplored. This study assessed the lethal and sublethal toxicity of PBAT/PLA biodegradation products combined with four soil-applied insecticides (abamectin, cyantraniliprole, sulfoxaflor, and t
In an era of rapid change and increasing societal demands, the role of universities as knowledge producers and catalysts for change has come under scrutiny. This open access book offers a fresh perspective on the significance of universities in society, shedding light on how their knowledge can truly matter beyond academia.Drawing upon insightful inquiries from both the Swedish and international c
Lime-cement mixing is a method used for ground improvement of clay soils. Before mixing at a field site, laboratory samples are prepared and tested to decide the amount of lime-cement binder needed to reach the desired material strength. Strength measurements are not possible before a sample hardens, and the test process to predict final strength takes 30 days. Resistivity measurements are possibl
Does the level of attention that politicians direct toward complex environmental problems impact how frontline bureaucrats in municipal settings form relationships? The collaborative interactions among civil servants are a defining feature of environmental governance, drastically shaping how issues are addressed. In this article, the authors incorporate political attention, or the priority status
Wildfires are a natural disturbance shaping boreal forests, but their effects on soil microbial communities and biogeochemical cycling remain unclear, particularly in Fennoscandia. We investigated the impact of fire severity and post-fire management on the soil microbial community two years after a boreal wildfire in Sweden. We quantified growth rates of bacteria, saprotrophic fungi (SF), ectomyco
Ideally a flux tower should be installed on a homogeneous and flat terrain. The surface should be physically homogeneous (same forest height and thermal properties) as well as be covered by same tree species, or in the case of the mixed forest, the distribution of the different species should be even (“well-mixed”). The fetch, the outreach of the homogeneous surface, should be longer than the exte
Critical infrastructure networks are susceptible to disruptions, and an imbalanced distribution of component importance can significantly amplify their vulnerability to cascading failures or targeted attacks. This study introduces a novel bi-objective optimization framework designed to enhance network resilience by strategically balancing component importance in multi-commodity spatial networks. T
Spatial compositional data with exact zeros arise in many applicationsbut remain challenging for models that often assume strictly positivecomponents. We develop a Bayesian spatial model that combines theDirichlet Composition Distribution, which accommodates exact zeros throughcomponent-specific zero probabilities, with a Gaussian Markov random field representationof the latent compositional field
