Traditional security studies focuses primarily on physical threats to the state. By contrast, the ontological security framework argues that individuals feel secure when they are able to maintain a communal narrative. Such a framework lends itself to an analysis of the impact of identity continuity on security. This thesis uses the ontological framework to understand the security issues that arise

I detta examensarbete undersöks databasen Plantfacts som innehåller data om stålverk från hela världen. Syftet med detta är att utvärdera om det finns en koppling mellan primärt och sekundärt producerat stål och olika typer av stålverk i downstream-processer. För att utföra detta har databasen formaterats om i Excel med hjälp av Visual Basic for Applications (VBA). Från början var Plantfacts databIn this thesis the Plantfacts database is investigated, which contains data about steel plants from all over the world. The purpose is to evaluate wheter there is a coupling between primary and secondary steel and different types of steel plants in downstream processes. To achieve this, the database has been reformatted using Visual Basic for Applications (VBA) in Excel. Initially, the Plantfacts

The issue of security is still an aspect of concern for domestic and international politics. In Southeast Asia, in 2003, the Association of Southeast Asian Nations (ASEAN) agreed to establish three pillars for the future single community by 2015: the ASEAN Political-Security Community (APSC), the ASEAN Economic Community (AEC), and the ASEAN Socio-Cultural Community (ASCC). To live at peace with o

Peking drabbades i januari 2013 av en smogkatastrof av aldrig tidigare uppmätt slag. Incidenten, känd som ”Airpocalypse”, blev en världsnyhet och satte mer än någonsin tidigare fokus på stadens omfattande luftföroreningsproblem. Den här uppsatsen redogör för omfattningen av och orsakerna bakom luftföroreningarna i Peking, och visar att stadens luftkvalitet redan på 80-, 90-, och 00-talen på många In January 2013 Beijing was hit with a wave of smog the likes of which have never been recorded before. The incident, known as ”Airpocalypse”, quickly made news across the globe placing focus on the City's immense air quality problem. This paper investigates the extent of and the reasons behind Beijing's air pollution, and goes on to show that the air quality during the 80's, 90's

Some colors might have different connotations depending on people’s cultural backgrounds. When talking about evacuation, the color employed for exit signs and flashing lights plays a significant role because it is in charge of transmitting a message to the evacuees, either danger or safety. The aims of this study are to evaluate the influence of red and green emergency wayfinding systems on people

I denna uppsats undersöker författaren en grupp kinesiska migrantarbetares syn på de egna arbets- och livsvillkor. De frågor relaterade till arbets- och livsvillkor som migrantarbetarna framför allt diskuterar i en sluten miljö och denna uppsats tar fasta på är arbetsskador, ensamhet, kollektivitet och arbetsrätt. Migrantarbetarnas skildringar är hämtade ur migrantarbetartidningen Jiemei Miyu

Efter det Stora språnget framåt svepte en svår hungersnöd över Kina. En längre period av ofördelaktigt väder och vänsterextrem politik gjorde att Henan drabbades extra hårt av svälten. Samtidigt som kannibalism härjade så genomdrev provinskommitténs förste sekreterare Wu Zhipu (吴芝圃) även insamlingen av det då största bidraget till den nationella spannmålsreserven någonsin. Det var Wus nit i att föThe economic policies of the Great Leap Forward led to a nationwide famine in the end of the 1950s. The starvation was especially severe in Henan due to a lengthy spell of unfavorable weather and leftist political policies. The situation was further aggravated by Henan's province committee's first secretary Wu Zhipu (吴芝圃) insisting on making the most ambitious contribution to the national

Lignans derived from Schisandra chinensis have attracted significant attention for their diverse pharmacological activities and clinical potential. This review presents a comprehensive analysis of the pharmacological properties of Schisandra chinensis lignans, including their antioxidant, anti-inflammatory, neuroprotective, hepatoprotective, antibacterial/viral, antidiabetic and anticancer effects

Objective To explore the feasibility of retroviral-mediated Flt 3 ligand (FL) and thrombopoietin (Tpo) genes transferred into and expressed in a bone marrow stromal cell line HFCL by internal ribosome entry site（IRES）sequence. Methods IRES sequence, FL and Tpo cDNA were recombined with retroviral vector pLXSN by gene recombination technology. The recombinant plasmid was transferred into retrovirus

Cardiopulmonary bypass (CPB) has been shown to be associated with systemic inflammatory response leading to postoperative organ dysfunction. Elucidating the underlying mechanisms and developing protective strategies for the pathophysiological consequences of CPB have been hampered due to the absence of a satisfactory recovery animal model. The purpose of this study was to establish a novel, minima

Background Non-heart-beating donor lung has been a promising source of lung transplantation. Many studies on non-heart-beating donor lungs are based on animal lung transplantation. In this study, we assessed by organ bath the effect of one-hour warm ischemia on the non-heart-beating donor lung in terms of the integrity of contractile and relaxant functions and tissue structures of pulmonic arterie
