The variations in atmospheric radiocarbon (C-14) concentration during the last 50 000 years can be attributed to changes in the C-14 production rate (due to changes in solar activity, the geomagnetic field and/or interstellar galactic cosmic ray flux) and to changes in the global carbon cycle. The relative contributions of these processes is the subject of current debate. Although the discrepancie
Capsazepine as well as its derivatives and analogues are general inhibitors of constriction of human small airways. From a systematic variation of the capsazepine structure, divided into four regions, SARs were established. This part concerns the catechol moiety of the A-ring as well as the 2,3,4,5-tetrahydro-1H-2-azepine moiety (the B-ring) of capsazepine. It is revealed that a conformational con
The results of a study on the phase behavior of the monoolein/water system with the addition of the hydrocarbon 1,8-cineole (C10H18O) and supercritical carbon dioxide at 15 MPa is presented. To two mixtures consisting of 9 and 18 wt.% water in monoolein, 5, 10, and 20 wt.% cineole were added and heated to between 35 and 80 degreesC at atmospheric pressure and in the presence of supercritical carbo
Within the cereal grasses, variation in inflorescence architecture results in a conspicuous morphological diversity that in crop species influences the yield of cereal grains. Although significant progress has been made in identifying some of the genes underlying this variation in maize and rice, in the temperate cereals, a group that includes wheat, barley, and rye, only the dosage-dependent and
This study is based on fine-mode aerosol samples collected in the upper troposphere (UT) and the lowermost stratosphere (LMS) of the Northern Hemisphere extratropics during monthly intercontinental flights at 8.8-12 km altitude of the IAGOS-CARIBIC platform in the time period 1999-2014. The samples were analyzed for a large number of chemical elements using the accelerator-based methods PIXE (part
Participation of stakeholders at the local level is evolving as a mechanism to address complex environmental problems, not least water pollution. Participation has been used as a tool for the economic and social empowerment of settlements within the catchment of the Korle lagoon in Ghana, particularly residents of the Old Fadama community that live in proximity to the lagoon. Using direct observat
Immunocytochemistry using antibodies against Met-enkephalin and Leu-enkephalin has demonstrated a group of large enkephalin-immunoreactive neurons in the nucleus of the rostral mesencephalic tegmentum (mRMT) of two teleost fish, Salmo gairdneri and Salmo salar. Injections of cobalt-lysine in the medial optic tectum retrogradely labeled the above group of tegmental neurons. Tegmental neurons were l
In recent years, the ability to make available, locate and access copyright protected content over the Internet has increased considerably. Some business models are directly aimed at linking or locating content already made available by other services. Such business models may create value for end users by making it easier to locate and find content on the Internet, but at the same time, they may
Urological problems can be caused by diseases that affect the bladder wall and its innervation. Contraction and relaxation of smooth muscle cells (SMCs) is essential for maintaining detrusor function and for emptying the bladder. It is well established that a family of regulatory proteins called Myocardin Related Transcription Factors (MRTFs) controls the property of SMCs. SMCs have a number
The aim of the research presented in this exploratory paper is to present the sustainability priorities and measures focused on by craft beer SMEs and to highlight a number of innovative measures pursued by brewers to promote sustainability. The materials and methods for the study included an Internet survey of craft breweries with a sustainability profile, followed by an in-depth analysis of 70 s
This article analyses the transnational production processes of foreign correspondence in the Cold War. It examines the double role of foreign correspondents as reporters and Cold War political agents. Recent scholarship has explored the activities of Western correspondents reporting from the Communist world. Little is known, however, about Eastern bloc correspondents in the West. Drawing on the r
BACKGROUND: While physical activity has been shown to affect psychological as well as physiological stress responses, less research has explored the effects of acute stress on athletic performance. The current study hence aimed to investigate the effect of an Acute Psychological Stress (APS) provocation on performance and plasma lactate concentration during a following 200m swim race among male el
Climate change may affect bird populations both directly by changing the weather conditions, and indirectly through changes in the food chain. While both theoretical and empirical studies have shown climate change having drastic impacts on polar areas, its consequences on Arctic bird species are still poorly known. Here we investigated how weather and changes in predator-prey interactions affected
This article aims to investigate how articulations of women’s relation to the welfare state and modes of political agency has changed in Sweden between 1977 and 2017; a period characterized by the introduction and implementation of a neoliberal political rationality. By way of discourse analysis, the article highlights the reciprocal relationship between the construction of the welfare state and w
Our understanding of the rises of animal and cancer multicellularity face the same conceptual hurdles: what makes the clade originate and what makes it diversify. Between the events of origination and diversification lies complex tissue organization that gave rise to novel functionality for organisms and, unfortunately, for malignant transformation in cells. Tissue specialization with distinctly s
