Abstract Hydrogel drug-delivery system that can effectively load antibacterial drugs, realize the in-situ drug release in microenvironment of wound infection to promote healing. In this study, a multifunctional hydrogel delivery (HA@TA-Okra) was constructed through integration hyaluronic acid methacrylate (HAMA) matrix with tannic (TA) and okra extract. The composition structural characteristics HA@TA-Okra its unique advantages treatment diverse wounds were systematically evaluated. TA, due...

Salmon farming is among the most successful aquaculture industries with a production growth that substantially higher than aggregate in recent decades. It well known innovations and productivity are main sources for this development. In article we look closer at two potentially important factors growth, development of farm size company directly through economies scale indirectly capacity R&D, innovation, sales marketing. Norway, per license has increased from 26 tons 1980 to 1,130 2010,...

The largest companies in salmon aquaculture are rapidly getting bigger due to organic growth as well mergers and acquisitions, the now multi-national companies. There two main explanations for this growth: 1) An attempt become large enough exploit market power, or 2) Size is necessary adopt new technologies that increase efficient scale. In paper, we investigate degree of concentration each producer countries Atlantic salmon, globally all farmed account global nature using...

In this paper, we investigate the impact of firm size and price variability on profitability in Norwegian salmon farming industry using a panel data set all companies from period 2000 to 2014. Several proxies for are included analysis. We find that firm's share total sales has positive profitability, while an alternative proxy, assets, is negatively linked profitability. Financial leverage (gearing) negative impact, but liquidity (current assets/current liabilities) not found significantly...

In response to climate change and environmental degradation, the European Union has recently proposed a long-term strategy targeting climate-neutral economy by 2050. Sustainable finance plays crucial role in reducing country's production-generated emissions since limited access credit hampers firms from investing pollution abatement technology. Additionally, high collateral requirements may force replace investment with tangible assets, which are often preferred as debt financing. Using...

The COVID-19 pandemic decreases firm revenue and raises the demand for liquidity, resulting in increased financial stress firms throughout world. In attempts to mitigate impact of crisis, governments have established a range credit programs provide with poor liquidity.

The COVID-19 pandemic has affected supply and demand to a large extent. Declining for firms' output caused significant financial stress all kinds of firms worldwide. Production that requires environmental measures usually gets constrained when firms, especially small medium-sized (SMEs), have difficulty in accessing credit. Firms thus face the dilemma whether continue behaviors or fulfill commitments suppliers, employees, so on. As such, an empirical question is economic consequences vary by...

In recent years there has been increased interest in the transaction forms salmon markets, given that contracts have become more common, vertical mergers create firms cover several levels supply chain, and futures markets developed as a price risk tool. These are strong indications chains developing same direction for processed food products. this article we investigate to what extent development influenced transmission process two product forms: relatively unprocessed one (fresh fillets)...

In recent years, eco-labeling has become an increasingly used tool to signal sustainable sourcing of (sea-) food. While the literature focused on price premiums associated with labels, it is noted in this paper that eco-labels can also contribute profitability by reducing cost, e.g. through longer product lifespans. Hence, be beneficial a supply chain even without premium. This study applies duration analysis explore whether two (the MSC label Marine Stewardship Council and line-caught...

The aquaculture industry has experienced substantial growth for many years. Moreover, high rates are projected to continue into the foreseeable future. Compared other species, salmon farming is one of most capital-intensive seafood industries, requiring investments in working capital, fixed assets, intangible assets (i.e., licenses), and innovation. Meanwhile, this exposed both production risk demand uncertainty. Surprisingly, investment behavior sector attracted very little research. In...

This study explores trade-offs between fish quality, fishing efficiency, costs and profitability across three different vessel groups in the Norwegian groundfish fishery, that is, vessels with bottom trawls, longlines Danish seines. The results of hedonic price analysis at ex-vessel level value chain indicate substantial differences quality as Atlantic cod caught obtain premiums 15.0 % 12.6 compared trawling seining, respectively, holding other variables constant.

This study focuses on fish quality and resource utilization at the ex-vessel level of value chain. Substantial waste in form reduced is revealed for Atlantic cod landed by coastal fleet Norway, with approximately 30% sampled from 399 catches downgraded, implying products onshore processing. By using an objective index individual hedonic price modeling, we obtain new insights regarding important role markets may play sustainable marine resources.

This study investigates the roles of different measures environmental performance in firms' financing choices. Environmental is measured through energy-efficiency investments, energy intensity, and consumption disclosures, which correspond to input-based, output-based, disclosing perspectives, respectively. We further distinguish between debt equity since information asymmetry varies across investors, affecting pecking order financial sources. use Eastern European Central Asian firm-level...

Abstract Perfect farm‐retail price transmission sometimes is taken to mean an elasticity of (EPT) equal 1. We show that this definition inconsistent with Gardner's (1975) model. also the absolute marketing margin (defined as difference between retail and farm price) responds differently shifts in demand, input supply, technical change marketers’ production function than does relative ratio price). The empirical implications these results are discussed some detail.
