Mate choice in plants is poorly understood, in particular its indirect genetic benefits, but also the direct benefits of avoiding harmful matings. In the herb Collinsia heterophylla, delayed stigma receptivity has been suggested to enhance pollen competition, potentially functioning as a female mate choice trait. Previous studies show that this trait can mitigate the cost of early fertilization ca
This reflection, based on a keynote address to celebrate the fortieth anniversary of Disasters on 14 September 2017, begins by considering some of the prevailing assumptions that existed at the time of the journal's creation. Next is a summary of significant milestones during the past 40 years, covering major global trends, changing disaster impacts, and key developments in disaster risk managemen
Time-dependent ensemble averages, i.e., trajectory-based averages of some observable, are of importance in many fields of science. A crucial objective when interpreting such data is to fit these averages (for instance, squared displacements) with a function and extract parameters (such as diffusion constants). A commonly overlooked challenge in such function fitting procedures is that fluctuations
The upcycling trend has received renewed attention in the past few years due to growing concerns for the environment related to increased resource consumption and waste volumes. Indeed, cities across the world are supporting resource upcycling initiatives by establishing do-it-yourself (DIY) repair cafes and makerspaces as a means to transform societies towards sustainable develop-ment. However, t
Astrocytes are emerging key players in neurological disorders. However, their role in disease etiology is poorly understood owing to inaccessibility of primary human astrocytes. Pluripotent stem cell-derived cells fail to mimic age and due to their clonal origin do not mimic genetic heterogeneity of patients. In contrast, direct conversion constitutes an attractive approach to generate human astro
Background: Obtaining reliable data under explicit evaluations is one of the most complicated challenges in assessing drug users' status. Respondents are likely to give answers that are to their advantage or deliberately deceitful. Regarding drug use, intense and inevitable drug craving is known as one of the main causes of relapse and treatment failure. As a matter of fact, drug craving is direct
Background: Mutations in BRCA2 cause a higher risk of early-onset aggressive prostate cancer (PrCa). The IMPACT study is evaluating targeted PrCa screening using prostate-specific-antigen (PSA) in men with germline BRCA1/2 mutations. Objective: To report the utility of PSA screening, PrCa incidence, positive predictive value of PSA, biopsy, and tumour characteristics after 3 yr of screening, by BR
The Great East Japan earthquake and tsunami hit coastal cities in Iwate, Miyagi and Fukushima Prefectures of Tohoku Region devastating the energy supply system in the region. Electricity and fuel shortages caused severe problems in the city of Kamaishi varying from lack of mobility, communication, heating to reduced health conditions. This paper, aims to analyze the impacts of the earthquake and t
CITED1 as a potential marker of treatment response in breast cancer Background Breast cancer is the most common form of cancer in women worldwide. In the clinic, breast cancer is generally divided into hormone dependent and independent form, based on whether tumor growth is driven by a certain hormone or not. Generally, patients with hormone-dependent breast cancer have a better prognosis compare
Agricultural fertilisation increases crop yields but can cause environmental damage, thus reductions in inorganic fertiliser application have been advocated. Farmer usage of phosphate rock has declined over the last decade, which may lead to soil nutrient depletion that undermines future crop production. We investigated the long-term (55 years) effects of eight different inorganic fertiliser regim
Most nitrogen and phosphorus transported by world rivers to the oceans is associated with dissolved organic matter. However, organic matter as a potential source of N and P has hitherto been largely neglected in studies of coastal microbial food webs. We examined 50 rivers, draining a major part of the Baltic Sea watershed, with respect to summer concentrations, chemical composition, and biologica
The primary purpose of this study was to establish an interaction effect between effortful control and neuroticism on problem‐solving coping. The secondary purpose was to examine the relationships between all three variables by establishing a correlation matrix. The sample consisted of 64 individuals, 18‐25 years old. The scores on the variables neuroticism and effortful control were used to creat
A kinetic model of the fermentative production of lactic acid from glucose by Lactococcus lactis ssp. lactis ATCC 19435 in whole-wheat flour has been developed. The model consists of terms for substrate and product inhibition as well as for the influence of pH and temperature. Experimental data from fermentation experiments under different physical conditions were used to fit and verify the model.
Investors are constantly searching for ways to protect their wealth, ideally without losing out on long-term returns. To achieve this, some investors choose to diversify their equity portfolios with fixed income assets, believing they can protect their portfolios from drawdowns. However, the current literature is divided on the effectiveness of fixed income assets as a shock-absorber during severe
Oxytocin (OT) is a small neuropeptide, which is present in human plasma at extremely low endogenous levels of only a few pg/ml. It is mainly involved during labour and lactation but it has recently also been found that OT is involved in social behaviours like bonding and feeling empathy. During the last couple of years, the interest in OT has been raised and due to the matrix complexity, it is ver
Vår uppfattning är att den strategi som många hemelektronikföretag väljer inte genererar en tillräcklig kundnytta. Oavsett bransch måste företag utgå från kunden eftersom det är den som idag styr marknaden. Vi saknar en sammanställning av de faktorer som ligger till grund för kundens tillfredsställelse som också skulle kunna hjälpa företag att leverera kundnytta. Syftet med uppsatsen är att unders
Climate change and disasters pose a serious risk to sustainable development. In the South local coping strategies are an important element of adaptation to climate and disaster risk. Such strategies have arisen because of the limited assistance provided by urban actors and associated social security and governance systems. In contrast, in the North local coping strategies are comparatively poorly
The development of integrated pest management is hampered by lack of information on how insect pest abundances relate to yield losses, and how pests are affected by control measures. In this study, we develop integrated pest management tactics for Apion spp. weevils (Coleoptera: Brentidae) in seed production of red clover, Trifolium pratense L. We tested a method to forecast pest damage, quantifie
The world supply and turnover of copper was modelled using simple empirical estimates and a COPPER systems dynamics model developed for this study. The model combines mining, trade markets, price mechanisms, population dynamics, use in society and waste as well as recycling, into a whole world system. The degree of sustainability and resource time horizon was estimated using four different methods
