The outstanding properties of graphene, a single graphite layer, render it a top candidate for substituting silicon in future electronic devices, The so far exploited synthesis approaches, however, require conditions typically achieved in specialized laboratories and result in graphene sheets whose electronic properties are often altered by interactions with substrate materials. The development of
Spectral estimation is an important classical problem that has received considerable attention in the signal processing literature. In this contribution, we propose a novel method for estimating the parameters of sums of complex exponentials embedded in additive noise from regularly or irregularly spaced samples. The method relies on Kronecker's theorem for Hankel operators, which enables us to fo
Based on a combined three locus analysis two new genera, Charcotiana and Amundsenia, are proposed in the lichen family Teloschistaceae, subfamily Xanthorioideae. Charcotiana includes the new species C. antarctica, which is known only from continental Antarctica. The bipolar genus Amundsenia includes the new species A. austrocontinentalis, which is also known only from continental Antarctica, and t
The long term radiological status of screw fixation following scoliosis surgery with all pedicle screw construct is not previously studied.
Abstract in UndeterminedThe manorial system was a salient feature of the pre-industrial economy in Europe from the early middle ages until the late nineteenth century. Despite its importance, it is not usually the main focus of eighteenth- and early nineteenth-century European economic history. Looking at a vital manorial economy, this article deals with land transmissions, a crucial factor in the
CdTe@Cu(OH)(2) nanocomposites were synthesized in aqueous solution by a seed-mediated growth approach. The effect of refluxing time and the concentration of Cu2+ on the preparation of these samples were measured using UV-visible absorption and photoluminescence analysis. The emission peak of the synthesized nanocomposites (CdTe@Cu(OH)(2)) was shifted from 605 (CdTe seed) to 621 nm. The size of CdT
The use of biofuels for road transport in Sweden has increased during the past 10 years as policymakers stimulate demand in response to concerns about climate change. Using a supply chain approach, this paper analyses: (i) existing biofuel supply chains in Sweden (biogas, biodiesel and bioethanol) in terms of security of supply, and (ii) possibilities to achieve synergies between implementation of
Abstract in Norwegian Ved passivering er det vanligvis hovedverbet som får passiv form, mens hjelpeverb og hjelpeverbsaktige verb ikke berøres. Men både i norsk og dansk og svensk finner vi passivkonstruksjoner som avviker fra dette mønsteret. Det forekommer nemlig også at både hjelpeverb og hovedverb har passiv morfologi (dobbel passiv), eller at bare hjelpeverbet har slik markering (opp-ned-pass
For we have the experience of ourselves, of that consciousness which we are, and it is on the basis of this experience that all linguistic connotations are assessed, and precisely through it that language comes to have any meaning at all for us.
Kettle holes are widespread in moraine landscapes. Their hydrological properties may be very vulnerable to changes in climatic conditions. To increase our knowledge of how kettle holes function and how they may be affected by climate change requires a model that can be applied to a variety of them regardless of their properties. We used the PIRFICT time series model to simulate the water levels in
There is a general consensus that enterprise risk management’s (ERM) popularity has resulted from a response to pressure on organizations to holistically manage risk. Multiple frameworks for implementation of ERM contribute to an overall uncertainty regarding the essential components of ERM. This uncertainty carries forward to empirical studies of ERM where results regarding value creation are inc
The objective of the paper is to explore and give an overview of two central policy alternatives to improve the integration between the European Union and developing countries by removing barriers to trade: trade preferences and trade facilitation. The author reviews the relevant literatures and discusses the issues which constitute problems or opportunities for practitioners and researchers in bo
We hypothesized that habitats differing in water flow regime would differ in bacterial function either because of differences in the local environment, in bacterial community composition (BCC), or in the mechanism shaping BCC (community assembly). In 20 lakes and 17 inlet streams BCC was analyzed by terminal restriction fragment length polymorphism of the gene coding for 16S ribosomal RNA, and bac
A method for aspheric surface testing (AST) is presented in this paper. The method fundamentally draws on solving the irradiance transport equation (ITE). It is shown by simulation that the accuracy of ITE solution depends on proper selection of defocus distance and also demonstrate that the best defocus distance depends on peak to valley and spatial extend of phase distribution.

Background: It has been estimated that approximately 20% of all Swedish children grow up with parents having alcohol problems, which may result in negative outcomes among these children. Therefore, most Swedish municipalities provide resources for support, but at the same time figures reveal that not even 2% receive support, mainly due to difficulties in identifying and recruiting these children i
Increased risk of Hodgkin lymphoma (HL) associated with personal history of several autoimmune diseases (ADs), such as rheumatoid arthritis, systemic lupus erythematosus, sarcoidosis, and immune thrombocytopenic purpura, are known. Whether there are other HL-related ADs and whether the increased risk of HL after ADs holds across sex, age, year of diagnosis, or HL histological subtype is unclear. W
It is usually assumed that musculoskeletal pain is associated with both the physical workload and the psychosocial work environment, as well as with personal and lifestyle factors. This study aims to ascertain the prevalence of musculoskeletal pain in women with varying or different occupational exposures, and to explore the associations between musculoskeletal pain and the occupational and person
The paper reports the results of lichenological investigations in Asveja Regional Park (eastern Lithuania). A large part of the study was performed during the joint 18th Symposium of Baltic Mycologists and Lichenologists (BMLS) and Nordic Lichen Society meeting (NLF), September 19–23, 2011. A list of 259 species is presented, 30 of them are new to Lithuania. Arthonia helvola, Bacidina sulphurella,
