The MAX IV facility includes two storage rings operated at 1.5 GeV and 3 GeV, which are both designed to operate with a uniform, multibunch fill pattern. Both rings have a 100 MHz RF system and employ passive harmonic cavities to damp instabilities and increase Touschek lifetime. Recently, a discussion on timing modes at the MAX IV storage rings has been initiated by the user community. Creating o

The principles for today's international refugee policies were laid down in the years following World War II, with the creation of the UNHCR and the establishment of an international refugee convention. These years, which were the central phase in the development of a new refugee regime, are the topic. The refugee question is set in an East-West perspective. The rethoric of refugee policies is con

This chapter reassesses the modernization processes at work in Republican China during the Warlord period between 1911 and 1927 by focusing on corporate, public action by non-state interest groups and organizations. In particular, it looks at modes of corporate governing at the interface of business/economy and education: the realm of vocational education. The chapter examines a particularly illum

The pervasive use and insatiable demand for high-performance wireless devices globally are driving the development of new communication technologies and standards. In this chapter, we present advancements in the area of terminal antenna systems and describe how they play a major role in enabling strict performance requirements to be met in future systems. As opposed to conventional systems that do

Hepatitis B virus (HBV) has eight genotypes which have distinct geographical distributions. Studies comparing differences in the clinical outcomes of infections caused by strains with genotype-related variations in the HBV genome have largely compared genotypes B and C and genotypes A and D but not all four genotypes. The present study included 196 HBV-infected patients attending an infectious dis

In this work, we examine how to reliably exploit baseline diversity of a multichannel interferometric SAR system to overcome the layover problem. The problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or discontinuities in the sensed scene. Several multilook approaches have recently been suggested to c

Neoplastic disorders are characterized by recurrent somatically acquired chromosomal aberrations that alter the structure and/or expression of a large number of genes. Most “cancer genes” discovered to date in human neoplasms have been identified through isolation of genes at the breakpoints of balanced chromosomal translocations. Although functional studies of such cancer-causing genes have demon

There is a great need for improved methods for the diagnosis of tuberculosis by techniques that are appropriate for control programs in low-income countries. Liquefaction of sputum with sodium hypochlorite followed by concentration of bacilli through overnight sedimentation significantly increases the sensitivity of direct microscopy, and this method could be an alternative for diagnostic centers

The Armauer Hansen Research Institute (AHRI) in Addis Abeba, Ethiopia, was established by the Swedish and Norwegian Save the Children organisations in collaboration with the University of Bergen, with the principal objective of pursuing basic research in leprosy. The institute has a commendable record of achievement, and has made significant contributions to our understanding of leprosy and its co

Objective: Rate of non-attendance following invitation for breast cancer screening is related to several socioeconomic conditions. To what extent this reflects differences with regard to individual and environmental circumstances, respectively, has received little attention. The purpose of this study was to investigate the effect of individual socioeconomic and area-level determinants on variation

Moraxella catarrhalis is a human-restricted commensal that over the last two decades has developed into an emerging respiratory tract pathogen. The bacterial species is equipped with various adhesins to facilitate its colonization. Successful evasion of the human immune system is a prerequisite for Moraxella infection. This strategy involves induction of an excessive proinflammatory response, inte

The phenotype of human immunodeficiency virus type 1 (HIV-1) commonly evolves between and within infected individuals, at virus transmission, and during disease progression. This evolution includes altered interactions between the virus and its coreceptors, i.e., chemokine receptors, as well as mannose C-type lectin receptors (CLRs). Transmitted/founder viruses are predominantly restricted to CCR5
