The material was collected during 12 summer expeditions organized from Diversity; 1997 to 2013. In all, 24 pelagic and 116 benthic taxa were recorded, most of them widely Distribution distributed Arctic-boreal species. The advection of different water masses from the shelf had a direct impact on the structure of the pelagic Malacostraca communities, resulting in the clear dominance of the sub-arctic hyperiid amphipod Themisto abyssorum in Kongsfjorden and the great abundance of Decapoda larvae in Hornsund. The taxonomic, functional and size compositions of the benthic malacostracan assemblages varied between the two fjords, and also between the glacier-proximate inner bays and the main fjord basins, as a result of the varying dominance patterns of the same assemblage of species. There was a significant drop in species richness in the strongly disturbed glacial bays of both fjords, but only in Hornsund was this accompanied by a significant decrease in density and diversity, probably due to greater isolation and poorer quality of sediment organic matter in its innermost basin.

    IMPROVEMENTS IN THE PERFORMANCE AND UNDERSTANDING OF SWITCHABLE-HYDROPHILICITY SOLVENTS by Jesse R. Vanderveen A thesis submitted to the Department of Chemistry In conformity with the requirements for the degree of Doctor of Philosophy Queen’s University Kingston, Ontario, Canada April, 2018 Copyright © Jesse R. Vanderveen, 2018 Abstract Switchable-hydrophilicity solvents (SHSs) are amine and amidine solvents that can be reversibly switched between two forms: one that forms a biphasic mixture with water and another that forms a monophasic mixture with water. The addition or removal of CO2 from SHS-based systems acts as the trigger to switch between these two forms. SHSs have attracted attention as alternative solvents for a variety of applications because their switchable behaviour allows them to be used in energy- or material- efficient ways. One such application is distillation-free solvent- solute separations. The present research builds an understanding of the properties of amines that determine whether they are SHSs or not. It also applies this understanding to the development of new SHSs with fewer health and environmental hazards, such as decreased acute toxicity and decreased volatility, as well as improved performance with respect to solvent-solute separations. The relationship between the pKaH and log Kow of an amine and the ability of the amine to act as a SHS is established. A mathematical model is described that can be used to predict whether an amine acts as a SHS based on these two properties. Furthermore, the influence of CO2 partial pressure and the water/amine volume ratio on these pKaH and log Kow requirements are investigated.

DOI: 10.3934/environsci.2016.3.488 Received: 29 April 2016 Accepted: 05 August 2016 Published: 10 August 2016 http://www.aimspress.com/journal/environmental Research article Diet of an underappreciated benthic intertidal fish, Cryptacanthodes maculatus (Cryptacanthodidae), in eastern Maine, USA Brian F. Beal1,*, Summer D. Meredith1, Cody B. Jourdet2 and Kyle E. Pepperman2 1 University of Maine at Machias, 116 O’Brien Avenue, Machias, ME 04654, USA 2 Downeast Institute for Applied Marine Research & Education, 39 Wildflower Lane, Beals, ME 04611, USA * Correspondence: Email: [email protected]; Tel: +1-207-255-1314. Abstract: We discovered through gut-content analysis over a 20-month period (June 2009–March 2011) that a little-known benthic fish, the wrymouth, Cryptacanthodes maculatus, preyed upon soft-bottom fauna from 8 phyla, 10 classes, and 28 genera in the lower intertidal/ shallow subtidal zone in Cobscook Bay (eastern Maine, USA). Wrymouth (N = 42; total length = 30–50 cm) live infaunally in extensive subterranean burrows, and consumed mainly polychaetes and amphipods that occurred in 80% and 75% of stomachs, respectively. The two most common polychaetes, Alitta virens and Harmothoe imbricata, were found in 60% and 25% of stomachs, respectively. Gammarideans Leptocheirus pinguis and Ampelisca abdita were the two most common amphipods occurring in 40% and 33% of stomachs, respectively. Benthic core samples taken from the mid- and low shore were ambiguous in helping to understand where wrymouth forage. Wrymouth likely contribute to trophic linkages between the intertidal and subtidal zones in soft-bottoms; however, its relative role in regulating benthic community structure, aspects of its reproductive behavior, and early life-history is unknown due in part to its cryptic lifestyle.

  • Formulation, Optimization, and Evaluation of Self-Emulsifying Drug Delivery Systems of Nevirapine
    Original Research Article Formulation, optimization, and evaluation of self-emulsifying drug delivery systems of nevirapine Ramprasad Chintalapudi, T. E. G. K. Murthy, K. Rajya Lakshmi, G. Ganesh Manohar1 Department of Pharmaceutics, Bapatla College of Pharmacy, Bapatla, 1Department of Pharmaceutical Analysis, Nirmala College of Pharmacy, Mangalagiri, Guntur, Andhra Pradesh, India Abstract Background: The aim of the present study was to formulate and optimize the self-emulsifying drug delivery systems (SEDDS) of nevirapine (NVP) by use of 22 factorial designs to enhance the oral absorption of NVP by improving its solubility, dissolution rate, and diffusion profile. SEDDS are the isotropic mixtures of oil, surfactant, co-surfactant and drug that form oil in water microemulsion when introduced into the aqueous phase under gentle agitation. Materials and Methods: Solubility of NVP in different oils, surfactants, and co-surfactants was determined for the screening of excipients. Pseudo- ternary phase diagrams were constructed by the aqueous titration method, and formulations were developed based on the optimum excipient combinations with the help of data obtained through the maximum micro emulsion region containing combinations of oil, surfactant, and co-surfactant. The formulations of SEDDS were optimized by 22 factorial designs. Results: The optimum formulation of SEDDS contains 32.5% oleic acid, 44.16% tween 20, and 11.9% polyethylene glycol 600 as oil, surfactant, and co-surfactant respectively. The SEDDS was evaluated for the following drug content, self-emulsification time, rheological properties, zeta potential,in vitro diffusion studies, thermodynamic stability studies, and in vitro dissolution studies. An increase in dissolution was achieved by SEDDS compared to pure form of NVP.
