Although the vinegar fly Drosophila melanogaster isarguably the most studied organism on the planet,fundamental aspects of this species’ natural ecologyhave remained enigmatic [1]. We have here investigateda wild population of D. melanogaster from amopane forest in Zimbabwe. We find that these fliesare closely associated with marula fruit (Sclerocaryabirrea) and propose that this seasonally abunda
The lifetimes of 17 even-parity levels (3d5s, 3d4d, 3d6s and 4p2) in the region 57 743–77 837 cm−1 of singly ionized scandium (Sc ii) were measured by two-step time-resolved laser induced fluorescence spectroscopy. Oscillator strengths of 57 lines from these highly excited upper levels were derived using a hollow cathode discharge lamp and a Fourier transform spectrometer. In addition, Hartree–Foc
Improved water, sanitation and hygiene (WASH) are significant in preventing diarrhea morbidity and mortality caused by protozoa in low- and middle-income countries. Due to the intimate and complex relationships between the different WASH components, it is often necessary to improve not just one but all of these components to have sustainable results. The objective of this paper was to review the c
Lakes and vegetation are important factors of the Earth's hydrological cycle and can be called an “indicator” of climate change. In this study, long-term changes of lakes' area and vegetation coverage in the Qinghai-Tibetan Plateau (QTP) and their relations to the climate change were analyzed by using Mann-Kendall method during the past 30 years. Results showed that: 1) the lakes' area of the QTP
An investigation of the fundamental frequency in Swedish feedback words is presented. It is hypothesised that the F0-pattern differs between words signalling positive and negative feedback-i.e. agreement and disagreement with the utterance of the preceding speaker. When imitating the contrast, the negative feedback word nej 'no' is often produced with a falling F0, stretching over a larger range,
Spotted fever group (SFG) Rickettsia species are inoculated into the mammalian bloodstream by hematophagous arthropods. Once in the bloodstream and during dissemination, the survival of these pathogens is dependent upon the ability of these bacteria to evade serum-borne host defenses until a proper cellular host is reached. Rickettsia conorii expresses an outer membrane protein, Adr1, which binds
Bacterial proteases are important enzymes used in several technical applications where controlled cleavage of proteins is needed. They are challenging enzymes to express recombinantly as parts of the proteome can be hydrolyzed by their activity. The eukaryotic model organism Saccharomyces cerevisiae is potentially a good expression host as it tolerates several stress conditions and is known to bet
Gastric cancer is a dominating cause of cancer-associated mortality with limited therapeutic options. Here, we show that syndecan-4 (SDC4), a transmembrane proteoglycan, is highly expressed in intestinal subtype gastric tumors and that this signature associates with patient poor survival. Further, we mechanistically demonstrate that SDC4 is a master regulator of gastric cancer cell motility and in
Visual information can be integrated in prominence perception, but most available evidence stems from controlled experimental settings, often involving synthetic stimuli. The present study provides evidence from spontaneously produced head gestures that occurred in Swedish television news readings. Sixteen short clips (containing 218 words in total) were rated for word prominence by 85 adult volun
Soil is an interface of the lithosphere, biosphere, hydrosphere and atmosphere that provides a habitat for microbial growth. The microbial biomass forms an integral part of the soil. The physiological potential and diversity of the microbial communities in soils are strongly associated with the physicochemical properties of soils. The biotic and abiotic characteristics determine the structure and
This chapter focuses on communication-centered change research and its implications for public sector organizations. It focuses on the organizational level and the communication processes through which changes are enacted. Special attention is given to coworkers and how they make sense in times of changes. Sensemaking processes play a crucial role in organizational changes; if managers and employe
Circular Economy regulation is rapidly adopted at different levels of governance, including municipalities, private and industry standards, national law and supranational standard-setting. There are increasing demands from policymakers, businesses and civil society for theoretical insights and more knowledge on the effects of policies and laws ('policy learning'). However, despite this mounting in

Since its emergence in late 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has continuously evolved, giving rise to multiple variants that have significantly altered the trajectory of the COVID-19 pandemic. These variants have resulted in multiple waves of the pandemic, exhibiting characteristic mutations in the spike (S) protein that may have affected receptor interaction, tis
Manufacturing Renaissance, i.e. return of manufacturing to west, has been recently observed. This paper analyzes the patterns observed within each of the four main drivers behind this new phenomenon and delves more deeply into the driver that centers on the new manufacturing technologies such as Additive Manufacturing (AM) and 3D Printing. Next, this paper will make the case that the location of m
Spores of pathogenic fungi are virtually ubiquitous and cause human disease and severe losses in crops. The endophytic fungi Alternaria species produce host-selective phytotoxins. Alt a 1 is a strongly allergenic protein found in A. alternata that causes severe asthma. Despite the well-established pathogenicity of Alt a 1, the molecular mechanisms underlying its action and physiological function r
