Because of the stratospheric ozone depletion that took place during the last decades of the past century, the effects of ultraviolet radiation on plants, animals, humans and micro-organisms became intensively studied. In this chapter we describe the role of the ozone layer as a radiation shield and various molecular and organismal effects of ultraviolet radiation, with an emphasis on the UV-B band
The chapter introduces the overriding question of the volume—whether poor countries can catch up—by providing an overview of theories and approaches that have contributed to this discussion. It argues for the importance of introducing to the analysis the role of structural transformation and to acknowledge that the conditions for economic development vary from case to case. Instead of clinging on
Popular Abstract in Swedish Avhandlingen följer den konfliktladdade relationen mellan far och son i Sven Delblancs författarskap och visar hur en lysande berättarkonst växer fram i samspelet mellan minne och fiktion.In 1991, a year before his death, Sven Delblanc published his highly acclaimed autobiography, Livets ax. At the centre of these childhood memories lies the author’s problematic relationship to his father. In view of the attention attracted by Livets ax, it is not surprising that biographical interpretations of Delblanc’s oeuvre have been predominant. It is evident that the writer’s difficult child
Fe 0 fluorescence by PAR has been investigated in eight symbiotic starshaving a wide range in temperature of the hot component and orbitalperiod. The data used are spectra obtained from the IUE archive. Allpumping lines investigated in this work are in the short wavelengthregion of IUE (1200-2000 Å), except for He 0 λ 1084.942 andO 0 λ 1032.041. The resulting Fe 0 fluorescence lines are mainlyin t
The photochemistry of low lying excited states of six different fluorinated bromobenzenes has been investigated by means of femtosecond laser spectroscopy and high level ab initio CASSCF/CASPT2 quantum chemical calculations. The objective of the work was to investigate how and to what extent light substituents, position on the benzene ring and number, would influence the dissociation mechanism of
The efficacy of a short (Group I) and a prolonged (Group II) course with ciprofloxacin was assessed in patients undergoing transurethral prostatic resection for benign hyperplasia or cancer of the prostate and compared with that of controls without antibiotic (Group III). Both regiments significantly reduced the frequency of postoperative bacteriuria (p less than 0.01) and of severe infectious com
A method and a model are presented aiming at enabling collection, structuring and analyzes of data concerning interdependencies between critical infrastructures and societal functions. A key distinction of the approach is the separation of actors and flows, where dependencies between actors, ranging from small municipal authorities to international private companies, are mediated through flows. Fl
Brain tumors are the most common solid tumors in children. Current treatment protocols fail in 25% of patients and are associated with significant long-term adverse effects in survivors. Experimental models of these tumors are scarce and will be crucial for the development of more efficient treatment strategies, including molecular targeting and immunotherapy. In this thesis, I describe the establ
Background and purpose — Impaction bone grafting (IBG) in revision hip surgery is an established method in restoring bone stock deficiencies. We hypothesized that local treatment of the morsellized allograft with a bisphosphonate in cemented revision would, in addition to increased bone density, also reduce the early migration of the cup as measured by radiostereometry (RSA). Patients and methods
This paper seeks to improve the understanding of the interaction between patients with stroke and the physical environment in their home settings. Stroke care is increasingly performed in the patient's home. Therefore, a systematic review was conducted to identify the existing knowledge about facilitators and barriers in the physical environment of home settings for the stroke rehabilitation proce
Purpose Competence is a prerequisite to achieve a well-functioning and competitive supply chain (SC). The purpose of this review is to present an integrated view of the published literature on all the aspects and facets of supply chain competence, and to present a framework for classification and analysis to facilitate further study, practice and research. Design/methodology/approach A structured
The authors discuss CCTV, which is now established as a mature and ubiquitous technology. They review existing research on CCTV as backdrop to introduce an alternative re-narration that stresses its use as an advanced information technology—a socio-technology. Central to this perspective is the recognition that system effectiveness hinges on a match of individual, organizational and technological
Due to an increased number of complex multi- and long-term ill patients, healthcare and nursing provided in patients' homes are expected to grow. Teamwork is important in order to provide effective and safe care. As care becomes more complex, the need for teamwork in home care nursing increases. However, the literature on teamwork in the patients' home environment is limited. The aim of this study
To assess the life-cycle welfare effects of pension reforms, we provide a dynamic stochastic model of saving, portfolio choice, and retirement featuring a rich characterisation of the pension system. Relying on the exogenous variation from a sequence of Italian pension reforms, we identify and estimate the model, which is then used to draw implications of alternative pension policies. The validate
Observations of ionized H αgas in high-redshift disc galaxies have ubiquitously found significant line broadening, σH α∼10 -100 km s-1 . To understand whether this broadening reflects gas turbulence within the interstellar medium (ISM) of galactic discs, or arises from out-of-plane emission in mass-loaded outflows, we perform radiation hydrodynamic simulations of isolated Milky Way-mass disc galax
This article applies the history of emotions lens to study the emotions experienced by the ‘comfort women’ in the Japanese Empire. Emotions have been a long-neglected aspect in the study of military sexual violence. The article examines how a mélange of positive and negative emotions enabled those women to exercise some limited agency in a confined and tightly regulated space and, in some rare cas
BACKGROUND: The Oesophago-Gastric Anastomosis Audit (OGAA) is an international collaborative group set up to study anastomotic leak outcomes after oesophagectomy for cancer. This Delphi study aimed to prioritize future research areas of unmet clinical need in RCTs to reduce anastomotic leaks.METHODS: A modified Delphi process was overseen by the OGAA committee, national leads, and engaged clinicia
Hypotension after cardiac arrest could aggravate prolonged hypoxic ischemic encephalopathy. The association of circulatory shock at hospital admission with outcome after cardiac arrest has not been well studied. The objective of this study was to investigate the independent association of circulatory shock at hospital admission with neurologic outcome, and to evaluate whether cardiovascular comorb
