Radijus utjecaja oborine nad područjem monsuna u Indiji

The paper describes an analysis of rain gauge data to determine an appropriate radius of influence to use for the objective analysis of rainfall over Indian monsoon region. The correlation co-efficient (CC) of rainfall between rain gauges in discrete distance intervals is computed, and the distance at which CC falls to 0.3 is chosen as the radius of rainfall influence. The method is applied for the monthly mean rainfall observations for June, July and August of Indian summer monsoon 2001. The method is also tested for a few case studies in relation to varying geographical and synoptic situations. The study shows that the radius of influence of rainfall over Indian region, in general, is around 200 km, but it has certain day to day variations depending on the prevailing synoptic conditions. The finding of the study is expected to be very useful for the objective analysis of rainfall over Indian region.Ova studija prikazuje analizu mjerenja kišomjernih postaja radi određivanja odgovarajućeg radijusa utjecaja za potrebe objektivne analize oborine nad područjem monsuna u Indiji. Računao se koeficijent korelacije oborine između kišomjernih postaja na diskretnim intervalima te je koeficijent korelacije od 0.3 odabran kao radijus oborinskog utjecaja. Metoda je primijenjena na srednje mjesečne vrijednosti oborine za razdoblje lipanj-kolovoz 2001. tijekom ljetnog monsuna u Indiji. Ova je metoda također testirana na nekoliko odabranih slučajeva zbog variranja geografskih i sinoptičkih situacija. Studija pokazuje da je radijus utjecaja oborine nad područjem monsuna u Indiji općenito oko 200 km, iako postoji određena dnevna varijabilnost koja ovisi o prevladavajućim sinoptičkim uvjetima. Rezultati ove studije korisni su za potrebe objektivne analize oborine nad područjem Indij

Izdvajanje, molekularna obilježja i otpornost na antibiotike enterotoksigenih (ETEC) i nekrotoksigenih sojeva E. coli izdvojenih iz zdravih azijskih vodenih bivola.

The present study was undertaken to detect the prevalence, virulence gene profile and antibiotic resistance of Enterotoxigenic Escherichia coli (ETEC) and Necrotoxigenic E. coli (NTEC) in healthy water buffalo in West Bengal. Out of the 363 E. coli isolates from 165 faecal samples, 18 (4.95%) and 7 (1.9%) isolates were found to possess genes for ETEC (LT or STa or STb) and NTEC (cnf1 or cnf2), respectively in PCR. Among the 18 ETEC isolates, 13 (72.22%), 12 (66.67%), and 1 (5.56%) isolates were found to harbour STa, LT, and STb genes respectively. However, among the 7 NTEC isolates, 3 (42.85%) and 4 (57.14%) were detected to possess cnf1 and cnf2 genes, respectively. Further, among the five isolates possessing the EAST 1 gene, four were detected with the STa gene and one (1) with the LT gene. However, the majority of the F41 strains possessed ST genes, and F5 strains harboured both LT and ST. In addition, one out of three cnf1 NTEC isolates was detected to harbour the papC gene and all the four cnf2 NTEC isolates contained the cdt gene. The ETEC isolates belonged to 11 different serogroups (O11, O53, O71, O84, O88, O103, O112, O120, O128, O153, and O158), while, four NTEC isolates belonged to the OUT serogroup and the remaining 3 were disseminated among the O2, O4, and O6 serogroups. The RAPD of the ETEC isolates produced different electrophoretic profifi les. The antibiotic resistance of ETEC and NTEC isolates was observed most frequently to amikacin (56%), kanamycin (44%), gentamicin (40%), neomycin (36%). The study thus revealed water buffalo as a reservoir of multi drug resistant ETEC/NTEC for the first time in India.Istraživanje je provedeno s ciljem da se ustanovi prevalencija, geni za virulenciju i otpornost na antibiotike enterotoksigenih (ETEC) i nekrotoksigenih (NTEC) sojeva bakterije Escherichia coli izdvojene iz zdravih vodenih bivola iz Zapadnog Bengala. Od 363 izolata E. coli iz 165 uzoraka fecesa, 18 (4,95%) je posjedovalo neki od gena za ETEC (LT ili STa ili STb), a sedam (1,9%) izolata imalo je gene za NTEC (cnf1 ili cnf2) dokazane PCR-om. Od 18 izolata ETEC, 13 (72,22%) je imalo gen STa, 12 (66,67%) gen LT i jedan (5,56%) gen STb. Međutim, od sedam NTEC izolata, tri (42,85%) su imala gen cnfl , a četiri (57,14%) gen cnf2. Nadalje, od pet izolata koji su posjedovali gen EAST 1, četiri su imala gen Sta, a jedan gen LT. Većina sojeva F41 posjedovala je gen ST, a sojevi F5 i LT i ST gen. Nadalje, jedan od triju cnf1 NTEC izolata imao je i gen papC, a sva četiri izolata cnf2 NTEC sadržavala su gen cdt. Izolati ETEC pripadali su u 11 različitih seroloških skupina (O11, O53, O71, O84, O88, O103, O112, O120, O128, O153 i O158). Četiri izolata NTEC pripadala su serološkoj skupini OUT, a preostala tri skupinama O2, O4 i O6. RAPD izolata ETEC davao je različite elektroforetske profile. Izolati ETEC i NTEC najčešće su bili otporni na amikacin (56%), kanamicin (44%), gentamicin (40%) i neomicin (36%). Ovim istraživanjem prviput je u Indiji ustanovljeno da su vodeni bivoli rezervoar multiplo rezistentnih sojeva ETEC/NTEC

Pseudomonas Genome Database: improved comparative analysis and population genomics capability for Pseudomonas genomes

Pseudomonas is a metabolically-diverse genus of bacteria known for its flexibility and leading free living to pathogenic lifestyles in a wide range of hosts. The Pseudomonas Genome Database (http://www.pseudomonas.com) integrates completely-sequenced Pseudomonas genome sequences and their annotations with genome-scale, high-precision computational predictions and manually curated annotation updates. The latest release implements an ability to view sequence polymorphisms in P. aeruginosa PAO1 versus other reference strains, incomplete genomes and single gene sequences. This aids analysis of phenotypic variation between closely related isolates and strains, as well as wider population genomics and evolutionary studies. The wide range of tools for comparing Pseudomonas annotations and sequences now includes a strain-specific access point for viewing high precision computational predictions including updated, more accurate, protein subcellular localization and genomic island predictions. Views link to genome-scale experimental data as well as comparative genomics analyses that incorporate robust genera-geared methods for predicting and clustering orthologs. These analyses can be exploited for identifying putative essential and core Pseudomonas genes or identifying large-scale evolutionary events. The Pseudomonas Genome Database aims to provide a continually updated, high quality source of genome annotations, specifically tailored for Pseudomonas researchers, but using an approach that may be implemented for other genera-level research communities

The embedding of transnational entrepreneurs in diaspora networks:Leveraging the assets of foreignness

In this paper we examine how foreign actors capitalize on their ethnic identity to gain skills and capabilities that enable them to operate in a new and strange environment. We explore the mechanisms by which Bulgarian entrepreneurs in London use their ethnic identity to develop competitive advantage and business contacts. We find that the entrepreneurs studied gain access to a diaspora network, which enables them to develop essential business capabilities and integrate knowledge from both home and host country environments. The diaspora community possesses a collective asset (transactive memory) that allows its members to remove competition from the interfirm level to the network level (i.e., diaspora networks vs. networks of native businesspeople). Additionally, the cultural identity and networks to which community members have access provide bridging capabilities that allow diaspora businesspeople to make links to host country business partners and thus embed themselves in the host country environment. Thus, this paper adds to the growing body of work showing how foreignness can serve as an asset in addition to its better-known role as a liability

Defining the Pseudomonas Genus: Where Do We Draw the Line with Azotobacter?

The genus Pseudomonas has gone through many taxonomic revisions over the past 100 years, going from a very large and diverse group of bacteria to a smaller, more refined and ordered list having specific properties. The relationship of the Pseudomonas genus to Azotobacter vinelandii is examined using three genomic sequence-based methods. First, using 16S rRNA trees, it is shown that A. vinelandii groups within the Pseudomonas close to Pseudomonas aeruginosa. Genomes from other related organisms (Acinetobacter, Psychrobacter, and Cellvibrio) are outside the Pseudomonas cluster. Second, pan genome family trees based on conserved gene families also show A. vinelandii to be more closely related to Pseudomonas than other related organisms. Third, exhaustive BLAST comparisons demonstrate that the fraction of shared genes between A. vinelandii and Pseudomonas genomes is similar to that of Pseudomonas species with each other. The results of these different methods point to a high similarity between A. vinelandii and the Pseudomonas genus, suggesting that Azotobacter might actually be a Pseudomonas

Consensus coding sequence (CCDS) database: a standardized set of human and mouse protein-coding regions supported by expert curation.

The Consensus Coding Sequence (CCDS) project provides a dataset of protein-coding regions that are identically annotated on the human and mouse reference genome assembly in genome annotations produced independently by NCBI and the Ensembl group at EMBL-EBI. This dataset is the product of an international collaboration that includes NCBI, Ensembl, HUGO Gene Nomenclature Committee, Mouse Genome Informatics and University of California, Santa Cruz. Identically annotated coding regions, which are generated using an automated pipeline and pass multiple quality assurance checks, are assigned a stable and tracked identifier (CCDS ID). Additionally, coordinated manual review by expert curators from the CCDS collaboration helps in maintaining the integrity and high quality of the dataset. The CCDS data are available through an interactive web page (https://www.ncbi.nlm.nih.gov/CCDS/CcdsBrowse.cgi) and an FTP site (ftp://ftp.ncbi.nlm.nih.gov/pub/CCDS/). In this paper, we outline the ongoing work, growth and stability of the CCDS dataset and provide updates on new collaboration members and new features added to the CCDS user interface. We also present expert curation scenarios, with specific examples highlighting the importance of an accurate reference genome assembly and the crucial role played by input from the research community.

An intimate and imperial feminism: Meliscent Shephard and the regulation of prostitution in colonial India

This paper seeks to construct an antinostalgic portrait of an imperial feminist. As the representative of the Association for Moral and Social Hygiene (AMSH) in India between 1928 and 1947, Meliscent Shephard was an embodiment not only of the feminist urge to challenge patriarchal gender relations, but also of the imperialist urge to classify and fathom the world through a series of racist typologies. Despite an earlier belief that blame for the exploitation of prostitutes lay with the colonial state and economy, she later fell back on explanations based on notions of Indian society and religion. Operating in a period of heightened anticolonial nationalism, these latter views thwarted any hope of her forging successful connections with emergent Indian social reform groups. This failure to cultivate intimate relations with Indian colleagues marks a failure at the level of national and racial politics. Shephard did, however, cultivate an intimate relationship with correspondents at the AMSH in London, while her experiences of the sexual geographies of Indian cities provided a form of intimate interaction that would inspire her mission to close down tolerated brothels. As such, this paper marks an empirical engagement with the intimate frontiers at which the affective grid of colonial politics was marked out

Genome Sequence Analyses of Pseudomonas savastanoi pv. glycinea and Subtractive Hybridization-Based Comparative Genomics with Nine Pseudomonads

Bacterial blight, caused by Pseudomonas savastanoi pv. glycinea (Psg), is a common disease of soybean. In an effort to compare a current field isolate with one isolated in the early 1960s, the genomes of two Psg strains, race 4 and B076, were sequenced using 454 pyrosequencing. The genomes of both Psg strains share more than 4,900 highly conserved genes, indicating very low genetic diversity between Psg genomes. Though conserved, genome rearrangements and recombination events occur commonly within the two Psg genomes. When compared to each other, 437 and 163 specific genes were identified in B076 and race 4, respectively. Most specific genes are plasmid-borne, indicating that acquisition and maintenance of plasmids may represent a major mechanism to change the genetic composition of the genome and even acquire new virulence factors. Type three secretion gene clusters of Psg strains are near identical with that of P. savastanoi pv. phaseolicola (Pph) strain 1448A and they shared 20 common effector genes. Furthermore, the coronatine biosynthetic cluster is present on a large plasmid in strain B076, but not in race 4. In silico subtractive hybridization-based comparative genomic analyses with nine sequenced phytopathogenic pseudomonads identified dozens of specific islands (SIs), and revealed that the genomes of Psg strains are more similar to those belonging to the same genomospecies such as Pph 1448A than to other phytopathogenic pseudomonads. The number of highly conserved genes (core genome) among them decreased dramatically when more genomes were included in the subtraction, suggesting the diversification of pseudomonads, and further indicating the genome heterogeneity among pseudomonads. However, the number of specific genes did not change significantly, suggesting these genes are indeed specific in Psg genomes. These results reinforce the idea of a species complex of P. syringae and support the reclassification of P. syringae into different species
