Molecular cloning of full-length coding sequences and characterization of α chains for donkey (Equus asinus) type I collagen

Donkey (Equus asinus) is a good donor for the collagen production. However, the information on mRNA and protein of donkey collagen has never been reported. In this work, the cDNA sequences coding proα1 and proα2 chains of donkey type I procollagen were determined from six and seven overlapping RT-PCR products, respectively. Further characterization of deduced amino acid sequences detailed the propeptides, telopeptides and triple-helical regions in donkey type I procollagen and collagen chains. Two proα chains of donkey type I procollagen share high similarities with corresponding sequences in mammalian species observed in this study. Considering the significance of lysine and proline in the structure and function of collagen, the distribution patterns of these two characteristic residues in α chains of donkey type I collagen were observed. The mRNA expression levels of type I collagen in donkey tissues were evaluated by quantitative real-time PCR.Keywords: Collagen, Col1a1, Col1a2, donkey, complementary DNAAfrican Journal of Biotechnology Vol. 12(27), pp. 4290-430

An assessment of technology forecasting: Revisiting earlier analyses on dye-sensitized solar cells (DSSCs)

© 2018 Elsevier Inc. The increasingly uncertain dynamics of technological change pose special challenges to traditional technology forecasting tools, which facilitates future-oriented technology analysis (FTA) tools to support the policy processes in the fields of science, technology & innovation (ST&I) and the management of technology (MOT), rather than merely forecasting incremental advances via analyses of continuous trends. Dye-sensitized solar cells are a promising third-generation photovoltaic technology that can add functionality and lower costs to enhance the value proposition of solar power generation in the early years of the 21st century. Through a series of technological forecasting studies analyzing the R&D patterns and trends in Dye-sensitized solar cells technology over the past several years, we have come to realize that validating previous forecasts is useful for improving ST&I policy processes. Yet, rarely do we revisit forecasts or projections to ascertain how well they fared. Moreover, few studies pay much attention to assessing FTA techniques. In this paper, we compare recent technology activities with previous forecasts to reveal the influencing factors that led to differences between past predictions and actual performance. Beyond our main aim of checking accuracy, in this paper we also wish to gain some sense of how valid those studies were and whether they proved useful to others in some ways

Modular input-parallel output-series DC/DC converter control with fault detection and redundancy

Large offshore wind farms require extensi ve sub-sea cables within the collection network. Present solutions are based aro und medium-voltage AC collection networks. Recent studies have highlighted the poten tial benefits of DC collection networks. However, achieving DC/DC conversion at th e required voltage and power levels presents a significant challenge for wind-tu rbine power electronics. This paper proposes an alternative DC collection network based around a modular DC/DC converter with input-parallel output-series (IPOS) connection. This modular topology can overcome the limitations imposed by semiconduct or voltage ratings and provides fault-tolerant operation. Small-signal analysis of the converter is presented to be used to facilitate controller design for the converter inpu t and output stages. A new master- slave control scheme and distributed voltage sharin g controllers are proposed that ensure power sharing under all operating conditions , including during failure of a master module. This control scheme achieves fault-t olerant operation by allowing the status of master module to be reallocated to any he althy module. The proposed control scheme is validated using simulation and experiment ation, considering active power sharing between modules with parameter mismatch
