Design of Submerged Offshore Reefs for the Coastal Protection Measure

Coastline is an interface between the ocean and the land. Coastal erosion is recession of the shoreline and loss of land area due to action of waves, currents and wind. Human interference also contributes to the adverse effects along the coastline, including the erosion. The physical regime of the Indian coastline is characterized by different types of coastal features. In order to mitigate the…

Isotope Targeted Glycoproteomics (IsoTaG) to Characterize Intact, Metabolical…

Protein glycosylation plays many critical roles in biological function and creates the most diversity of all post-translational modifications (PTMs). Glycan structural diversity is directly correlated with difficulty in characterizing the intact glycoproteome by mass spectrometry (MS). In this protocol, we describe a novel mass-independent chemical glycoproteomics platform for characterizing in…

Rapid Assays for Lectin Toxicity and Binding Changes that Reflect Altered Gly…

Glycosylation engineering is used to generate glycoproteins, glycolipids, or proteoglycans with a more defined complement of glycans on their glycoconjugates. For example, a mammalian cell glycosylation mutant lacking a specific glycosyltransferase generates glycoproteins, and/or glycolipids, and/or proteoglycans with truncated glycans missing the sugar transferred by that glycosyltransfera…

Theorising capitalist diversity: The uneven and combined development of labou…

This article seeks to elaborate a framework for the study of diversity in forms of labour using Trotsky’s theory of uneven and combined development (UCD). It argues that labour markets are constituted by systemic processes of capital accumulation and uneven development in the global economy, but that these processes have highly differentiated outcomes in terms of the forms of labour that…

Labour as a transnational actor, and labour’s national diversity as a syste…

This paper argues that one strong and still largely uncontested theoretical heritage of mainstream approaches to capitalist diversity, and particularly the varieties of capitalism framework, is the binding of labour’s agency to national institutions and (cultural and ‘mental’) ‘paths’. This has been the main paradigm within political and trade union debates, too, especially in Germany…

Transformation and crisis in Central and Eastern Europe: A combined and uneve…

This article elaborates a theory of combined and uneven development that takes the dimensions of spatiality, labour and institutions seriously. Drawing on this conceptual framework, an account is given of the way the 2007–2008 crisis was inflected in the countries of Central and Eastern Europe. The integration of these countries with the global economy has taken place in different ways throug…
