Bin är en del av den biologiska mångfalden och bidrar dessutom med pollineringstjänster i våra odlade grödor och trädgårdsväxter. Men många arter är hotade och minskar i antal, med minskande biologisk mångfald som följd. Vilka konsekvenser får detta för jordbruksproduktionen? Genom att identifiera hoten och hitta motåtgärder finns det hopp om en väg framåt som gynnar alla.
Climate warming has caused the seasonal timing of many components of ecological food chains to advance. In the context of trophic interactions, the match–mismatch hypothesis postulates that differential shifts can lead to phenological asynchrony with negative impacts for consumers. However, at present there has been no consistent analysis of the links between temperature change, phenological async
Dual-energy X-ray absorptiometry (DXA)-derived appendicular lean mass/height2 (ALM/ht2) is the most commonly used estimate of muscle mass in the assessment of sarcopenia, but its predictive value for fracture is substantially attenuated by femoral neck (fn) bone mineral density (BMD). We investigated predictive value of 11 sarcopenia definitions for incident fracture, independent of fnBMD, fractur
Purpose: Lemierre syndrome is a life-threatening condition characterized by head/neck bacterial infection, local suppurative thrombophlebitis and septic embolic complications in a range of sites of distant organs. No prior study focused on the course and characteristics of ophthalmic complications of Lemierre syndrome. Methods: We analysed data of 27 patients with ophthalmic complications from a l
Internally structured block copolymer-surfactant particles are formed when the complex salts of ionic-neutral block copolymers neutralized by surfactant counterions are dispersed in aqueous media. Here, we report the1H NMR signal intensities and self-diffusion coefficients (D, from pulsed field gradient nuclear magnetic resonance, PFG NMR) of trimethyl alkylammonium surfac-tant ions and the poly(a
Little is known about the extent of variation and activity of naturally occurring milk glycosidases and their potential to degrade milk glycans. A multi-omics approach was used to investigate the relationship between glycosidases and important bioactive compounds such as free oligo-saccharides and O-linked glycans in bovine milk. Using 4-methylumbelliferone (4-MU) assays activities of eight indige
Human rely profoundly on tactile feedback from fingertips to interact with the environment, whereas most hand prostheses used in clinics provide no tactile feedback. In this study we demonstrate the feasibility to use a tactile display glove that can be worn by a unilateral hand amputee on the remaining healthy hand to display tactile feedback from a hand prosthesis. The main benefit is that users
Since the turn of the century, agriculture in sub-Saharan Africa has been undergoing rapid transformation. Ghana is experiencing an agrarian revolution with increasing farmland sizes, increased mechanisation of production and external input usage, and high levels of commercialisation. In this paper we show the growth of farm sizes, the major drivers of increasing farm sizes, and emerging relations
Extracts of Diprion similis females contained about 15 ng of the sex pheromone precursor 3,7‐dimethylpentadecan‐2‐ol per female. After derivatisation with (S)‐2‐acetoxypropanoyl chloride, we found that the major stereoisomer in the extract was (2S,3R,7R)‐3,7‐dimethylpentadecan‐2‐ol. Small amounts of other stereoisomers of 3,7‐dimethylpentadecan‐2‐ol were also identified in the extract, namely 1% o
Pregnancy may influence cellular immune responses to Mycobacterium tuberculosis. We investigated M. tuberculosis-specific interferon-g responses in women followed longitudinally during pregnancy and postpartum. Interferon-g levels (stimulated by M. tuberculosis antigens [TB1 and TB2] and mitogen included in the QuantiFERON-TB Gold Plus assay) were measured in blood from pregnant HIV-negative women
In this chapter, we explore not only the challenges with public procurement, but also how public organization can turn procurement into a useful tool that can help develop quality in public services provision and delivery. There is a belief that public procurement can be an instrument for change. The public sector is a large procurer, and the idea is that if public procurers demand better products
Context. We present a systematic X-ray spectral-timing study of the recently discovered, exceptionally bright black hole X-ray binary system MAXI J1820+070. Our analysis focuses on the first part of the 2018 outburst, covering the rise throughout the hard state, the bright hard and hard-intermediate states, and the transition to the soft-intermediate state. Aims. We address the issue of constraini
This chapter aims to discuss challenges related to governing in a digitalized era. In the public sector, digitalization and ICT solutions are regarded as a way to alleviate the burden of a sector under pressure. The suggested solutions are many, from computers making decisions to robots substituting teachers. Through digitalization resources can be freed up and public service provision be delivere
The focus of this article is to examine a specific case of a failing regional innovation system (RIS). Our study focuses on a specific project that was conducted in a triple helix constellation where public actors occupy the centre of the triple helix constellation. By examining and interpreting this single case, we aim to illustrate the consequences that result from uncertainty over who the tripl
Exporting is a central growth strategy for most firms and managers with international experience are instrumental for export decisions. We suggest that such managers can be hired from Multinational Corporations (MNCs). We integrate theory from strategic human capital research into models explaining export decisions. We theorize that hiring managers from MNCs increases the odds of domestic firms to
The steeply falling jet spectrum induces a bias on the medium modifications of jet observables in heavy-ion collisions. To explore this effect, we develop a novel analytic framework to study the quenched jet spectrum and its cumulative. We include many energy-loss-related effects, such as soft and hard medium induced emissions, broadening, elastic scattering, jet fragmentation, cone size dependenc
Ice multiplication by fragmentation during collision-freezing of supercooled rain or drizzle is investigated. A zero-dimensional dynamical system describes the time evolution of number densities of supercooled drops and ice crystals in a mixed-phase cloud. The characteristic time scale for this collision-freezing ice fragmentation is controlled by the collision efficiency, the number of ice fragme
