Seagrass production in Minicoy Atoll of Lakshadweep Archipelago
Get PDFMinicoy lagoon harbours extensive beds oiThalassia hemprichii in apsociation
with Syringodium isoetifolium, Halophila ovalis and Halodule uninervis. The
total area occupied by seagrass flat ranges from 2.0 to 2.2 sq.km. Net primary
production (NPP) of seagrass species varied from 5.0 gC/mVday (0.5 gC/kg (wet
wt.)/day for Syringodium to 10 gC/m¥day (1.0 gC/kg (wet wt.)/day for Halodule.
It was estimated that an impairement upto 50 % on the NPP of Thalassia
plants was caused by the prolonged exposure of the beds to bright sunshine
in the intertidal areas during ebb stage when compared to those Thalassia
plants growing in the unexposed habitats. Wet biomass, density of seagrass
species and their NPP potential on the community metabolism of the lagoon
are discussed
Bivalirudin versus heparin in primary PCI: clinical outcomes and cost analysis.
Get PDFBackground: The evidence for benefits of bivalirudin over heparin has recently been challenged. We aimed to analyse the safety and cost-effectiveness following reintroduction of heparin instead of bivalirudin as the standard anticoagulation for primary percutaneous coronary intervention (PPCI) in a high-volume centre. Methods and results: This analysis was an open-label, prospective registry including all patients admitted to our centre for PPCI from April 2014 to April 2016. Heparin was reintroduced as standard anticoagulant in April 2015. During the 2 years, 1291 patients underwent a PPCI, 662 in the Bivalirudin protocol period (Cohort B) and 629 in the Heparin protocol period (Cohort H). Baseline and procedural characteristics were not significantly different, except for a higher use of thromboaspiration and femoral access in the earlier Cohort B. Glycoprotein 2b3a (Gp2b3a) antagonists were used in 24% of the patients in Cohort B versus 28% in Cohort H (P<0.01). We did not observe any differences in death at 180 days (11.03% in Cohort B vs 11.29% in Cohort H)(HR 95% CI 0.98 (0.72 to 1.33), P=0.88). The incidence of any bleeding complications at 30 days did not differ between the two periods (21.9% vs 21.9%, P=0.99). The cost related to the anticoagulants amounted to £246 236 in Cohort B versus £4483 in Cohort H (£324 406 vs £102 347 when adding Gp2b3a antagonists). Conclusion: We did not find clinically relevant changes in patient outcomes, including bleeding complications with reintroduction of heparin in our PPCI protocol. However, the use of heparin was associated with a major reduction in treatment costs
Hatchery seed production and cage farming of Tiger grouper Epinephelus fuscoguttatus (Forsskal 1775) in Andaman and Nicobar Islands, India
Get PDF1678-1685Grouper fishes have been considered as commercially important candidate species for aquaculture. Among them, the Tiger grouper (Epinepheleus fuscoguttatus) is one of the most relished finfish that demands an excellent price in the fish markets of Southeast Asia. Rajiv Gandhi Centre for Aquaculture (RGCA), has launched a project on breeding, seed production and grow out farming of grouper at Andaman & Nicobar Islands (ANI). The project developed technology for breeding and grow-out farming of Tiger grouper, which is widely distributed in Andamans and also form a candidate species for captive breeding and sea cage culture. Its wild catches are extremely limited and insufficient to meet the huge market demands. Hence, development of a standard technology for the seed production of Tiger grouper is an imperative to boost the country’s export revenue. The paper presented here, is one such initiative by RGCA on seed production and cage culture of E. fuscoguttatus

The Publisher's final version can be found by following the DOI link.Globalisation has brought a number of challenges to the fore, particularly those problems which require collaboration, innovation and capability development between nations. There are some complex issues piquing the attention of researchers with respect to sustainable development, such as, waste management, climate change, and access to amenities, housing or education. Non-Governmental Organisations, Institutions, governments and others working in the field of international development have been grappling with these difficulties for decades. However, it is becoming apparent that many of these difficulties require multifaceted solutions, particularly in Low and Middle Income countries (LMIC) where it is difficult to consolidate gains and fund schemes. Development work can sometimes be disjointed and inefficient, impairing the capability of local communities and inhibiting sustainable and innovative approaches. Transdisciplinary collaboration is reliably a more efficient way of tackling some of the most pertinacious challenges. This paper presents findings from a transdisciplinary research project focussed on developing resources and capacity for the construction of affordable homes in a low income community in Nigeria. The project explored the suitability of using upcycled materials such as plastic bottles and agricultural waste in construction. Using a user-centred, co-creation methodology, a team of experts from the UK and Nigeria worked with local entrepreneurs to build a prototype home. The study explores the functionality of the home and the sustainability of project. The findings demonstrate the benefits of tackling global challenges from a transdisciplinary perspective. This has implications for researchers focused on developing technical solutions for low-income communities

Get PDFNot AvailableSurveys were undertaken to document the fauna of insects, spiders and
entomopathogenic nematodesacross India despite the travel restrictions due to COVID-19.
The expeditions undertaken yielded several species of natural enemies viz.,Chalcididae
(66.32%), Eulophidae (19.94%), Pteromalidae (4.14%) and Encyrtidae (3.37%) of
Hymenoptera and 14 species of trichogrammatids representing 7 genera. The predominant
genera of hymenopteran insect parasitoids were identified as Dirhinus Dalman (30.47%)
followed by Brachymeria Westwood (27.73%), Hockeria Walker (22.27%) and
Antrocephalus Kirby (18.75%). Revisionary studies of the braconid parasitoid, Apanteles
sp. ater-group including subgroup eublemmae of the genus (Hymenoptera: Braconidae) of
the Oriental region was carried out with an illustrated key, in which a total of 97 species
were recorded and illustrated. Three species of tachinid flies, Peribaea orbata on larva of
Spodoptera litura, Halidaia luteicornis on larva of Parnara sp., Sturmiopsis inferens on
larva of Sesamia inferens and Carcelia sp. from the larvae of Helicoverpa armigera
(Noctuidae) were identified and described.
The spider fauna of rice ecosystem was documented, where six species of long jawed orb
weaver, Tetragnatha species have been described of which T. keyserlingi was the
predominant species across the surveyed locations in Tamil Nadu. The species,
Tetragnathanitens collected from Tamil Nadu and Telangana was the first report from
India. The spitting spider, Scytodes fusca Walckenaer of family Scyotidae was redescribed
with documentation of variations in the vulval pattern of the female and theory about the
introduction of this Pantropical species to India.Not Availabl
