Japan started to accept foreign trainees from the 1960s. In the 1990s, Japan introduced an integrated foreign trainee and technical intern system, which has played an important role in the labour migration from China to Japan. However, the infractions of labour rights were found in this system, of which the Chinese Labour Agencies are the main causes. This thesis aims to explore the existing infra

The Single Molecule Spectroscopy Group at the department of Chemical Physics in the Chemical Centre of Lund University conducts research involving spectroscopy on single molecules of organic dyes. Fluorescence microscopy using a wide-field scheme has been used and such a scheme has many advantages such as full image capture at once when using a high sensitivity CCD or CMOS camera. Using different

Energy crisis and energy disruptions have contributed to the current securitization and politicization of energy within the European Union (EU). Today the energy policy is a part of the EU external relations, at the same time as the EU is regarded as an actor with the power to spread values and norms in the international arena. The EU Eastern Partnership, and the Association Agreements initiated i

The Northern Hemisphere experienced dramatic changes during the last glacial, featuring vast ice sheets and abrupt climate events, while high northern latitudes during the last interglacial (Eemian) were warmer than today. Here we use high-resolution aerosol records from the Greenland NEEM ice core to reconstruct the environmental alterations in aerosol source regions accompanying these changes. S

Dehydrogenase based bioelectrocatalysis has been increasingly exploited in recent years in order to develop new bioelectrochemical devices, such as biosensors and biofuel cells, with improved performances. In some cases, dehydrogeases are able to directly exchange electrons with an appropriately designed electrode surface, without the need for an added redox mediator, allowing bioelectrocatalysis

A socially mixed population is a political ambition in Stockholm. By providing a mix of tenure alternatives throughout all neighbourhoods this objective could, at least partially, be fulfilled. Since current tenure proportions display a weak balance in many neighbourhoods it could be assumed that governing politicians – by primarily utilizing Stockholm’s vast landownership and municipal housing de

It is estimated that the number of devices connected to the Internet will be 50 billion by 2020. How should a not-so-tech-savvy end user be able to discover and directly interact with a myriad of connected things in an intuitive and comfortable manner? Up until now, smartphones have shown potential for managing the Internet of Things (IoT) environments, but we cannot rely on that technology. Weara

By utilizing the promising alternative fuel of syngas, and the syngas/diesel dual-fuel reactivity controlled compression ignition (RCCI) is a potential combustion strategy for internal combustion engines. However, the optimal operating parameters for syngas/diesel RCCI engines under wide operating conditions have not been investigated. In this study, the operating parameters include fuel supply, s

Intergenerational mobility has remained stable over recent decades in the United States but varies sharply across the country. In this article, I document that areas with more prevalent slavery by the outbreak of the Civil War exhibit substantially less upward mobility today. I find a negative link between prior slavery and contemporary mobility within states, when controlling for a wide range of

Development of antibody drugs against novel targets and pathways offers great opportunities to improve current cancer treatment. We here describe a phenotypic discovery platform enabling efficient identification of therapeutic antibody-target combinations. The platform utilizes primary patient cells throughout the discovery process and includes methods for differential phage display cell panning,

Assessment of breast density at the point of mammographic examination could lead to optimized breast cancer screening pathways. The onsite breast density information may offer guidance when to recommend supplemental imaging for women in a screening program. In this work, performance evaluation of a new software (Insight BD, Siemens Healthcare GmbH) for fast onsite quantification of volumetric brea

Water security offers to the local population an adequate quality and quantity of water for health, economy, livelihoods and ecosystems. Hence, achieving basic levels of water security should be a priority in areas where access to fresh water is scarce. The Punata alluvial fan (Bolivia) is a semiarid zone and an important agricultural zone, where the main source of water is groundwater. Therefore,
