Aims: Non-high density lipoprotein cholesterol (non-HDL-C) is gaining importance over low density lipoprotein cholesterol (LDL-C) as cardiovascular risk marker in patients with type 2 diabetes. It represents the overall lipid burden and is a surrogate marker for the apolipoprotein B. We studied the discordance between the old (LDL-C) and the new (non-HDL-C) lipid markers in a large group of diabetes patients. Methods: The lipid profile data of all diabetes (T2DM, aged 18-75, using oral or injectable anti diabetic agents) patients was analyzed in this study. We excluded patients with type1 diabetes, secondary forms of diabetes and gestational diabetes. Elevated lipid parameters (LDL. >. 100. mg/dL and non HDL-C. >. 130. mg/dL) were defined as per the guidelines of Adult Treatment Panel III. Results: The study participants (409 M:360 F) had a mean age of 47.3±12.4 years, BMI of 28.4±5.6kg/m2 and an A1c of 8.8±2.2%. Elevated LDL-C was observed in 383 patients (49.8%) and elevated non HDL-C in 418 (54.4%) patients. Of the 383 patients with elevated LDL-C, 346 (90.3%) had corresponding elevated levels of non-HDL-C and out of 418 patients with elevated non HDL-C, 346 (83%) had elevated LDL-C. Discordance between the elevated LDL-C and non-HDL-C values were greater among patients with low triglyceride levels when compared with those with high triglycerides (Pearson's χ 2 test=67.7; P <0.001). Conclusion: Our data suggest a significant discordance between the LDL-C and non-HDL-C in patients with diabetes. This discordance leads to the residual cardiovascular risk in diabetes patients. © 2015 Diabetes India.

Understanding water dynamics and the processes affecting water elevation in the lagoon is important in understanding how barrier-lagoon systems work and, in particular, how it affects sediment distribution and architecture. It is also important in resolving a number of environmental problems related to flooding and land management. Louro barrier-lagoon system, on the Atlantic coast (Ría de Muros, Spain), has been studied to observe water-stage fluctuations and boundary conditions for inflow and outflow, from November 2009 to June 2010. Louro barrier-lagoon is disconnected from the open sea most of the year and over the last 10 years it rarely opened. Nevertheless during the monitored interval from November 2009 to June 2010 it opened at least 5 times due to a particularly stormy year. Results show that when the berm is well-developed and the inlet is not open, marine waters enter the inner lagoon by over-passing the beach berm by over-spilling during high spring tides. Flooding waters enter the lagoon through a partial channel which shows a strong slope from the berm inwards, reaching a supercritical flow and introducing marine waters, far into the eastern part of the lagoon. The sand is transported inwards forming lobe-shaped bars into the lagoon and depositing a tidal flood-delta. However, to develop a fully open inlet, which involves the excavation of a channel, water over-elevation has to occur in the lagoon to build enough water pressure and potential energy to cut the berm and to connect the lagoon with the sea.

Coastal upwelling filaments off the Western Iberian Margin, detected in AVHRR satellite imagery and in a realistic ROMS simulation of sea surface temperature, were studied in the upwelling seasons (May-October) of 2001-2010. Sea surface temperature data were retrieved from AVHRR satellite imagery and from a realistic ROMS numerical simulation. The development and variability of the observed filaments were characterized and analyzed during each upwelling season of the 10 year period. Filaments were generally found anchored to the main bathymetric and coastal features but off the more regular northern coast of the Western Iberian Margin their locations were more variable. The results from the modeling analysis reproduced well the general features of filament development. Moreover results of model and observation showed very similar characteristics as those found in the earlier study of Haynes et al. (1993). The model output was used to relate filament patterns, eddy activity, and wind forcing. There was a clear relation between upwelling-favorable wind strength and number and length of filaments, although the relation was weaker in the north of the region. Model filaments were clearly related to eddies only during periods of weak winds. The filament detection method was also applied to a climatologically forced ROMS simulation, which reproduced only gross features of the observed and interannually forced model filament development. This suggests that direct wind forcing and its spatial structure are highly important. © 2015 American Geophysical Union. All Rights Reserved.

In a post disaster scenario, assessment of resource needs is indeed challenging because needs are constantly changing and supplies trickle in at an uncertain rate. Moreover, information about resource needs of far-flung areas get rarely permeated owing to the disruption of cellular and other communication infrastructure, leading to a huge gap in perception about the actual needs in those areas. Therefore, a dynamic need assessment mechanism is essential to stay abreast of the actual situation. Movements of volunteers and relief workers are governed by two dominant characteristics of human mobility - spatial locality and spatial regularity. In this paper, we make use of such mobility characteristics to propose a knowledge sharing based approach for dynamic assessment of post disaster resource needs using a smart-phone based delay tolerant network (DTN). The proposed technique caters to the objective of bridging the gap in perception about actual resource needs. © 2016 ACM.

In WDM optical networks, wavelength is the critical resource for efficient communication of traffic. Hence, suitable protocols are required to allocate and use the wavelengths efficiently. We have studied the wavelength reservation protocols of such networks, which are already developed and reported in literature. Following their historical development, we have outlined some generalized classification for them and provided comparison of their performances. Finally, on the basis of the previous works, we have discussed some future scopes, which may be explored for further improvement in performance of the protocols. © 2011 Elsevier Ltd.
