Smoked marine fish from Western Region, Ghana: a value chain assessment

The value chain analysis of ths report focused on smoked marine fish- overwhelmingly the most important fish product originating in Western Region, Ghana. Smoked fish from Western Region is mainly destined for the domestic market where demand is very strong. Small quantities of smoked fish are destined for markets in Togo, Benin and Nigeria. The underlying objective of the fisheries value chain analysis is to identify opportunities for growth in the fisheries value chain, with an emphasis on those opportunities that have the potential to generate significant additional livelihoods, particularly at the level of the fishing communities and for low-income groups. The results from the value chain analysis will be used to identify pilot interventions to promote those livelihood outcomes. The main focus for the study is smoked fish (major species/product forms) destined for domestic markets. However, work will also be undertaken on the fresh fish trade and frozen fish to find out more about the significance of these value chains

Erection of the Haploporid Genus \u3ci\u3eLitosaccus\u3c/i\u3e n. g. and Its Phylogenetic Relationship within the Haploporidae Nicoll, 1914

Litosaccus n. g. is erected for Paralecithobotrys brisbanensis Martin, 1974 n. comb. for which an amended description is given. The new genus is morphologically similar to the haploporine Lecithobotrys Looss, 1902 but with a more elongate and cylindrical body; an infundibuliform oral sucker; a thin-walled hermaphroditic sac; a shallow genital atrium; and unequal, cylindrical, and elongated caeca. It also resembles Pseudolecithobotrys Blasco-Costa, Gibson, Balbuena, Raga & Kostadinova, 2009, but the only member of that genus has a hermaphroditic sac that is twice the length of the ventral sucker, a hermaphroditic duct with intensely staining cuboidal cells, an elongate testis, and single or paired caeca. A Bayesian inference analysis of partial 28S rDNA sequences of L. brisbanensis and 24 other haploporoids revealed that L. brisbanensis grouped with other haploporines and placed Intromugil Overstreet & Curran, 2005 in a clade with the chalcinotrematine Saccocoelioides Szidat, 1954 rather than the other seven tested waretrematine species. This analysis represents the first phylogenetic study of the Haploporidae Nicoll, 1914 that incorporates a haploporine from outside of the Mediterranean Sea

Accessing highly substituted indoles via B(C6F5)3-catalyzed secondary Alkyl Group Transfer

Herein, we report a synthetic method to access a range of highly substituted indoles via the B(C6F5)3-catalyzed transfer of 2° alkyl groups from amines. The transition-metal-free catalytic approach has been demonstrated across a broad range of indoles and amine 2° alkyl donors, including various substituents on both reacting components, to access useful C(3)-alkylated indole products. The alkyl transfer process can be performed using Schlenk line techniques in combination with commercially available B(C6F5)3·nH2O and solvents, which obviates the requirement for specialized equipment (e.g., glovebox)

Electron deficient borane-mediated hydride abstraction in amines: stoichiometric and catalytic processes

The manipulation of amino C–H bonds has garnered significant interest from the synthetic community due to its inherently high atom, step and redox economy. This Tutorial Review summarises the ability of boranes to mediate hydride abstraction from α-amino and γ-amino conjugated C–H bonds. Borane-mediated hydride abstraction results in the generation of reactive iminium hydridoborate salts that participate in a variety of stoichiometric and catalytic processes. The reactions that have utilised this unusual reactivity include those that manipulate amino scaffolds (including dehydrogenation, racemisation, isomerisation, α- and β-functionalisation, and C–N bond cleavage) and those that use amine-based reagents (transfer hydrogenation, and alkylation)

Recent advances in catalysis using organoborane-mediated hydride abstraction

C–H functionalization is widely regarded as an important area in the development of synthetic methodology, enabling the design of more time- and atom-efficient syntheses. The ability of electron-deficient organoboranes to mediate hydride abstraction from α-amino C–H bonds is therefore of great interest, as the reactive iminium and hydridoborate moieties generated are able to participate in a range of synthetically useful transformations. In this review, we cover the recent advances made in organoborane-mediated hydride abstraction, and focus on the catalytic applications of electron-deficient boranes in α- or β-functionalization, α,β-difunctionalization, and the dehydrogenation of amines

Stereospecific conversion of alcohols into pinacol boronic esters using lithiation-borylation methodology with pinacolborane

The synthesis of primary and secondary pinacol boronic esters via lithiation–borylation of carbamates and benzoates with pinacolborane is described. This new protocol enables the highly selective synthesis of enantioenriched and geometrically defined boronic esters that cannot otherwise be accessed by alternative methodologies

From citizen science to jellyfish dispersion models and molecular studies : tracking the progress of jellyfish science in Malta (Central Mediterranean)

Following participation within the 1980”s FAO-mediated monitoring exercises of Pelagia noctiluca blooms within Maltese waters, little scientific effort was invested in studying the dynamics of jellyfish blooms within same waters and at developing management and public information strategies concerning the same blooms. A renewed scientific effort at studying such aspects within Maltese waters was registered from 2010 onwards, with the launch of the Spot the Jellyfish citizen science campaign (www.ioikids.net/jellyfish) which provided a user-friendly, multivalent and web-based through which maritime stakehold- ers and the public at large could submit their jellyfish records for Maltese waters. The web- based portal was also supported by other promotional initiatives in the field, such as the installation of seaside boards on beaches. Through this initiative, several previously-un- documented species of gelatinous plankton were recorded for the first time from the same waters, including Rhopilema nomadica, Aequorea forskalea, Porpita porpita, Discomedua lobata, Geryonia proboscidalis, Neotima lucullana, Physophora hydrostatica, Chrysaora hysoscella and Oceania armata. The maintenance of an updated jellyfish record database has been made possible through the conduction of such a citizen science initiative.peer-reviewe
