Directionality and complexity of L1 transfer in L2 acquisition: Evidence from L2 Chinese discourse

First language (L1) transfer is a common phenomenon in second language (L2) acquisition. However, it will be argued in this article that although there are indeed pervasive influences of learners’ L1 in L2 acquisition, L1 transfer is not everywhere and it can be directional. We compare data from Chang’s (2001b. Discourse effects on the second language acquisition of English and Chinese dative structures. Honolulu: University of Hawai’i at Manoa PhD dissertation, 2004. Discourse effects on EFL learners’ production of dative constructions. Journal of Kaohsiung University of Applied Sciences 33. 145–169.) studies of Chinese-speaking learners of English with data of our study of English-speaking learners of Chinese to examine whether their L2 English discourse and L2 Chinese discourse are equally influenced by their L1 discourse rules. We focus on learners’ answers to wh-questions with a double object construction or a prepositional object construction. The results demonstrate that L1 transfer takes place in Chinese-speaking learners’ L2 English discourse but not in English-speaking learners’ L2 Chinese discourse. This directionality of L1 transfer is accounted for on the basis of computational complexity of linguistic structures involved and on an economical consideration.

Technological and economical consideration for turbine blade tip restoration through metal deposition technologies

In the oil and gas industry, repair activities are critical to keep the maintenance costs of turbomachinery equipment down. Several repair technologies can be applied to various components of turbomachines. When dealing with gas turbines, the repair of turbine rotor blades has always been a very sensitive topic, given their critical application and their impact in terms of cost on the whole turbine lifecycle. Specifically, cracking and wearing of blade tips are some of the most common failure modes. Thus, the repair of these failure modes is of paramount importance, both for the original manufacturer as well as its aftermarket competitors. The present paper describes blade tip repair technologies from an original equipment manufacturer standpoint. Three different approaches are introduced and described for tip restoration. Laser cladding is presented first, since it is one of the most common technologies for this application, and then original equipment manufacturer which is currently being applied is presented. Then, cold metal transfer and direct metal laser melting technologies are investigated. A technologic and financial assessment is made to drive the technology selection for the turbine blades restoration.

Energy Storage System in Smart Homes of Smart City

The Nanogrid utilizes renewable energy sources, e.g. Solar PV, Wind, etc; which are stochastic in nature. Due to this nature, power reliability is the main issue. To increase the reliability of the power supply and proper utilization of the available resources, Nanogrid should either connected to the utility grid directly or it must have the proper energy storage system. Energy storage system fills the gap between consumers demand and renewable power generation; which is very important issue in technical and economical consideration. The Nanogrid gives new hope of ray to the people living in off grid areas. By using energy storage system we can increase their living standard and enhance socio-economical development. This paper proposes the selection of the proper energy storage device and its calculation, control strategy also suggested for protecting storage device from over voltage and deep discharge.

Urban consolidation centre – a literature review, categorisation, and a future research agenda

Purpose Urban consolidation centre (UCC) is a popular initiative targeting the challenge of negative environmental and social impacts from freight transports in cities. Despite this, UCC often fails in practice, which indicates a knowledge gap. Furthermore, research within the field can be described as fragmented, transdisciplinary and fast growing. The purpose of this paper is to provide an overview of the field by describing dominant categories and themes within the area, identify gaps in order to propose a future research agenda, and provide insights into the needs of practitioners. Design/methodology/approach A systematic literature review (SLR) targeting journal articles based on UCCs has been constructed with a supplementary snowball approach. A content analysis was performed to categorise themes in the research on UCCs and to identify research gaps, both within and outside the categories identified. Findings Despite substantial research on UCC, very little research ends up in academic journals. In all, 56 articles address UCC. The most common topics were the role of stakeholders, design of distribution structures and transport resources, environmental and social consideration, and economic considerations. Much focus is directed towards finding “optimal” solutions and designs for potential initiatives with very little, if any, consideration to financial viability or the management of the UCC initiative. Research limitations/implications This research points out existing gaps in the literature and proposes a future research agenda with UCCs as the focus. For example, although environmental and social arguments are often applied to justify the implementation of UCCs, few studies measure or evaluate their impact. Another important research gap is the economical consideration, both how to generate revenue and how to consider economies of scale. Practical implications The practical contribution of most studies is directed towards municipalities. Few findings are presented in a way to support companies. Additionally, by bridging the gaps related to how stakeholders can collaborate and describe what is happening in a UCC, practitioners can use such information as guidelines. Originality/value The results provide a research agenda for the fragmented research targeting UCCs, supporting the viability of future initiatives.

Extractive Fermentation of Ethanol from Sweet Sorghum Using Vacuum Fractionation Technique: Optimization and Techno-Economic Assessment

Direct extraction of high purity ethanol from fermentation broth was investigated using a vacuum fractionation technique. Batch and repeated-batch extractive fermentation of ethanol were carried out using concentrated sweet sorghum as a carbon source. The effect of product inhibition was reduced by continuous removing ethanol from the fermented broth. About 60 % relative viability was observed in fermented broth with a higher productivity value. Due to the high value of living cells presented in the medium, repeated-batch extractive fermentation was subsequently performed. The ethanol was continuously fractionated out from the system at the average rate of 10.2 g/h with the concentration of approximately 80 wt%. There were 8 cycles of fermentation using only 1 time inoculation. Nevertheless, the calculated ethanol productivity and relative viability for each fermentation cycle were decreased gradually due to the accumulation of toxic substances in fermented broth. The simulation of 200 liters continuous extractive fermentation system using ASPEN PLUS was studied including process optimization and economical consideration. 18.5 liters of ethanol solutions 82 wt% with insignificant amounts of by-product was produced from a 200 liters extractive fermentation system per day. Production cost including raw material and utilities cost was approximately 0.71 €/liter. The economic and systemic performance process were subsequently analyzed, and including that ethanol loss was recovered using a gas scrubber connected to the vapor exiting the venturi tank as well as in the stillage stream. The calculated utility costs after process modification were 0.5 €/liter of ethanol, approximately 30 % of production cost was reduced.
