Hydraulic model studies were carried out to optimise a layout of a fishing harbour on the west coast of India, in Kerala. A layout consisting of two breakwaters, 80 m long north breakwater and 670 m south breakwater (150 m normal to the shore and 520 m along the shore) with 100 m wide opening at the harbour entrance was initially proposed. The tranquillity conditions of proposed breakwater alig…
Groundwater in coastal aquifers of Nagapattinam and Karaikal regions are characterized by large saline variations with Conductivity levels up to (12,430.0 μS/cm). The high salinity collective with deterioration in water level creates a serious threat to current groundwater quality for human consumption. An integrated electrical resistivity and hydrogeochemical investigations were carried out t…
Development of a Jetty in an estuary with wide tidal flat is quite a challenging job as the approach channel to the deep water is a complicated issue where the disturbance to the natural hydrodynamic behaviour of the sea and the dynamic nature of the sediment movement is to be handled with utmost care. Flat slope causes reduction in velocity and there by formation of mudflats in water way. The …
In this manuscript, a study of the effect of microwave radiation on the high-performance liquid chromatography separation of tocopherols and vitamin K1 was conducted. The novelty of the application was the use of a relatively low polarity mobile phase in which the dielectric heating effect was minimized to evaluate the nonthermal effect of the microwave radiation over the separation process…
In coastal hydrodynamics, tides play a major role and it is important to understand the complexity of their characteristics along the difficult coastal areas like creeks, estuaries, bays and gulfs for any kind of engineering activities like harbor, jetty, dams and protection measures. In this study, six tidal constituents (K1, M2, N2, O1, P1 and S2) variations along the Gulf of Khambhat,west co…
Seawater intrusion generally occurs when withdrawal of fresh groundwater from coastal aquifers results in declining groundwater levels, facilitating lateral and/or vertical migration of saline water causing deterioration of groundwater quality. Electrical resistivity sounding techniques and hydrochemical studies are widely used to determine the interaction between groundwater and saline water/s…
The wave data measured using the Datawell directional wave rider buoy at 13 m water depth off Ratnagiri during 2010 to 2013 is used to study the inter-annual variations in the wave characteristics. The percentage occurrence of waves with significant wave height (Hs) less than 1 m is the same in all 3 years, but the occurrence of high waves (Hs > 1 m) is not same in all the years. The extreme wa…
Thermohaline variability in the Cochin estuary primarily depends on the mixing of fresh water downstream and sea water intrusion upstream. Knowledge of sea water intrusion into the estuary is important for functioning of ecological systems. Therefore this study explored the possibility of monitoring sea water intrusion into the estuary using open ocean thermohaline properties obtained from sate…

Three irrigation modes comprised…
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…
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…
O-linked N-acetylglucosamine (O-GlcNAc) glycosylation is a dynamic protein posttranslational modification with roles in processes such as transcription, cell cycle regulation, and metabolism. Detailed mechanistic studies of O-GlcNAc have been hindered by a lack of methods for measuring O-GlcNAc stoichiometries and the interplay of glycosylation with other posttranslational modifications. We rec…
The navigational aspects of marine transport and its manoeuvrability require precise knowledge on tides. Information on time varying water levels, magnitude and direction of tidal currents is quite critical in coastal waterways and estuarine environment. Real-time water levels along with other hydrodynamic parameters are used in almost all major ports for effective operations throughout the yea…
Extreme weather events such as tropical cyclones results in extensive devastation to coastal environment. The risk levels associated with cyclones that have landfall in the east coast of India is quite high, and hence there is a need to estimate as well forecast the damage risk associated with extreme winds, rainfall, storm surge, and associated coastal flooding during cyclonic events. In the p…

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…
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…
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…
The article charts the continuing attempt to breathe fresh life into the original Hall and Soskice distinction between liberal market economies (LMEs) and coordinated market economies (CMEs). It surveys the critique of that original formulation from within the dominant ‘varieties of capitalism’ paradigm, and the recent attempt by Wolfgang Streeck to replace the LME-CME focus with a new …
Sesamum orientale wild and cultivar Thilarani exposed to Alternaria sesami infection triggered the signal cascade H2O2 content that was positively correlated with lipid peroxidation.
