Opportunistic mobile social networks: architecture, privacy, security issues and future directions

Mobile Social Networks and its related applications have made a very great impact in the society. Many new technologies related to mobile social networking are booming rapidly now-a-days and yet to boom. One such upcoming technology is Opportunistic Mobile Social Networking. This technology allows mobile users to communicate and exchange data with each other without the use of Internet. This paper is about Opportunistic Mobile Social Networks, its architecture, issues and some future research directions. The architecture and issues of Opportunistic Mobile Social Networks are compared with that of traditional Mobile Social Networks. The main contribution of this paper is regarding privacy and security issues in Opportunistic Mobile Social Networks. Finally, some future research directions in Opportunistic Mobile Social Networks have been elaborated regarding the data's privacy and security

Unusual heavy landings of flying gurnards at Munambam Fishing Harbour

Flying gurnards belongs to the familyDactylopteridae, distributed in tropical Indo-Pacificand Atlantic oceans. From the 7 speciesrepresenting two genera, Dactylopterus andDactyloptena only four species such asDactyloptena gilberti, D. macracantha,D. orientalis and D. peterseni are found in thewestern Indian Ocean. These are small to moderatesized marine bottom dwelling fish and mostlycaught by bottom trawls as by-catch in the nearshore waters and not having much commercialvalue

Record sized longnose trevally landed

A large sized longnose trevally Carangoideschrysophrys (Cuvier, 1833) was landed at CochinFisheries Harbour on 19th September 2015. Belongingto the family Carangidae, it was caught by a hookand line unit operated near Lakshadweep waters

Occurrence of macro plastic in the stomach of flat needlefish

On 6th January 2016, biological samples ofAblennes hians were collected from the hook andline fishing boats based at Munambam FishingHarbour, Kochi. While analysing the gut contents inthe laboratory, the stomach of one specimen (weight380 gm, total length 687 mm) contained macroplastic material having about 0.02 gm weight.Stomach also contained partially digested shrimps,sea snails (Diacavolinia longirostris, Cavoliniatridentata) and digested matter

Genetic effects on gene expression across human tissues

Characterization of the molecular function of the human genome and its variation across individuals is essential for identifying the cellular mechanisms that underlie human genetic traits and diseases. The Genotype-Tissue Expression (GTEx) project aims to characterize variation in gene expression levels across individuals and diverse tissues of the human body, many of which are not easily accessible. Here we describe genetic effects on gene expression levels across 44 human tissues. We find that local genetic variation affects gene expression levels for the majority of genes, and we further identify inter-chromosomal genetic effects for 93 genes and 112 loci. On the basis of the identified genetic effects, we characterize patterns of tissue specificity, compare local and distal effects, and evaluate the functional properties of the genetic effects. We also demonstrate that multi-tissue, multi-individual data can be used to identify genes and pathways affected by human disease-associated variation, enabling a mechanistic interpretation of gene regulation and the genetic basis of diseas

A Biomarker Approach

The source, fate and diagentic pathway of sedimentary organic matter in estuaries are difficult to delineate due to the complexity of organic matter sources, intensive physical mixing and biological processes. A combination of bulk organic matter techniques and molecular biomarkers are found to be successful in explaining organic matter dynamics in estuaries. The basic requirement for these multi-proxy approaches are (i) sources have significantly differing characteristics, (ii) there are a sufficient number of tracers to delineate all sources and (iii) organic matter degradation and processing have little, similar or predictable effects on end member characteristics. Although there have been abundant researches that have attempted to tackle difficulties related to the source and fate of organic matter in estuarine systems, our understanding remains limited or rather inconsistent regarding the Indian estuaries. Cochin estuary is the largest among many extensive estuarine systems along the southwest coast of India. It supports as much biological productivity and diversity as tropical rain forests. In this study, we have used a combination of bulk geochemical parameters and different group of molecular biomarkers to define organic matter sources and thereby identifying various biogeochemical processes acting along the salinity gradient of the Cochin estuaryCochin University of Science and TechnologyDepartment of Chemical Oceanography School of Marine Sciences Cochin University of Science and Technolog

Distribution of REE’s Along South Coast of India

96-105Rare earth elements and radioactive elements like Th and U were measured in sediments from nine sampling locations along continental shelf regions of the south coast of India in order to study their behaviour and distribution environment. Analysis was performed using ICP/MS and normalised by using the Post-Archean Australian Shale composition. Rare earth elements grouped into LREE and HREE and the results showed high LREE than HREE indicating their abundance along the study area. Factor analysis and correlation results leads their origin may be from common source. Eu anomalies indicate the source may be from alkali-feldspar or hydrothermal source. Ce anomaly expresses the terrigenous source as origin and displayed oxic environment which prevails along the study region. Other depositional parameters like Authigenic-U, Th/U ration also support these results

Lines Conserving Cultural Heritage and Human Emotions: Archiving the Works of Artist Namboothiri

Artist Namboothiri's work span over a century. He is one of the most productive artists who presented the world using lines. Landscapes, cities, villages, heritage buildings even after many were lost long ago, people, costumes, festivals and rituals, traditional arts, along with characters of classics remain documented in sketches of Namboothiri. There is a possibility that his works also will be lost because in Indian art scenario book and magazine illustrations are not considered with the seriousness of other art works. But any of his illustration from those running to tens of thousands can stand with any important artwork of the world. We are yet to realize their heritage value and importance. Till now there was no attempt to list his work or conserve them from any quarters. From heritage conservation angle and heritage of Indian art his works needs to be preserved. This is an initial study and attempt to evolve a system 'Artist Namboothiri Open Access Digital Archive’ to document and preserve his works
