While in S. castaneae, the fan shaped comb is about 2/3 width of the valva, the median projection of the signum is long and somewhat ensiform (Kumata et al., 1988b). Description. Adult.

A Study of Smart Ventilation System to Balance Indoor Air Quality and Energy Consumption : A case study on Dalarnas Villa
No full textIt is a dilemma problem to achieve both these two goals: a) to maintain a best indoor air quality and b) to use a most efficient energy for a house at the same time. One of the outstanding components involving these goals is a smart ventilation system in the house. Smart ventilation strategies, including demand-controlled ventilation (DCV), have been of great interests and some studies believe that DCV strategies have the potential for energy reductions for all ventilation systems. This research aims to improve smart ventilation system, in aspects of energy consumption, indoor CO2 concentrations and living comfortness, by analyzing long-term sensor data. Based on a case study on an experimental house -- Dalarnas Villa, this research investigates how the current two ventilations modes work in the house and improves its ventilation system by developing customized ventilation schedules. A variety of data analysis methods were used in this research. Clustering analysis is used to identify the CO2 patterns and hence determine the residents living patterns; correlation analysis and regression analysis are used to quantify a model to estimate fan energy consumption; a mathematical model is built to simulation the CO2 decreasing when the house is under 0 occupancy. And finally, two customized schedules are created for a typical workday and holiday, respectively, which show advantages in all aspects of energy consumption, CO2 concentrations and living comfortness, compared with the current ventilation modes
Enhanced reversibility of the magnetoelastic transition in (Mn,Fe)<sub>2</sub>(P,Si) alloys via minimizing the transition-induced elastic strain energy
No full textMagnetocaloric materials undergoing reversible phase transitions are highly desirable for magnetic refrigeration applications. (Mn,Fe)2(P,Si) alloys exhibit a giant magnetocaloric effect accompanied by a magnetoelastic transition, while the noticeable irreversibility causes drastic degradation of the magnetocaloric properties during consecutive cooling cycles. In the present work, we performed a comprehensive study on the magnetoelastic transition of the (Mn,Fe)2(P,Si) alloys by high-resolution transmission electron microscopy, in situ field- and temperature-dependent neutron powder diffraction as well as density functional theory calculations (DFT). We found a generalized relationship between the thermal hysteresis and the transition-induced elastic strain energy for the (Mn,Fe)2(P,Si) family. The thermal hysteresis was greatly reduced from 11 to 1 K by a mere 4 at.% substitution of Fe by Mo in the Mn1.15Fe0.80P0.45Si0.55 alloy. This reduction is found to be due to a strong reduction in the transition-induced elastic strain energy. The significantly enhanced reversibility of the magnetoelastic transition leads to a remarkable improvement of the reversible magnetocaloric properties, compared to the parent alloy. Based on the DFT calculations and the neutron diffraction experiments, we also elucidated the underlying mechanism of the tunable transition temperature for the (Mn,Fe)2(P,Si) family, which can essentially be attributed to the strong competition between the covalent bonding and the ferromagnetic exchange coupling. The present work provides not only a new strategy to improve the reversibility of a first-order magnetic transition but also essential insight into the electron-spin-lattice coupling in giant magnetocaloric materials.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.RST/Fundamental Aspects of Materials and Energ
On the Translation of English Hard News under Inter-cultural Background
No full textThe author firstly introduced the characteristics of hard news form the perspectives of the structure, linguistic features and language style. Secondly, numerous cultural background factors are classified into six types including geographical environment, life style, traditional customs, religious beliefs, historical allusion and literature connotations which are the underlying causes of cultural barriers occurred in the hard news translation. To remove the cultural barriers, based on the Lawrence Venuti’s (1995) foreignization and domesticaiton translation theory, the paper presents principles for hard news translation. By giving a large number of instances of hard news translations, this paper mainly focuses on such issues as the characteristics of hard news, the influence of the inter-culture on the hard news translation, and relevant translation strategies, and last but not least, attaches significance to the inter-culture awareness of the translator during the process of hard news translation.</jats:p
Highly permeable acid-resistant polyamine hollow fiber nanofiltration membrane fabricated by secondary interfacial polymerization reactions
No full textThe development of acid-resistant nanofiltration (NF) membranes has drawn much attention due to their application in industrial wastewater treatment. In this work, we utilized polyethyleneimine (PEI) and cyanuric chloride (CC) to conduct the first interfacial polymerization (IP) reaction on the polyethersulfone (PES) hollow fiber substrate, followed by the secondary IP process using tris(2-aminoethyl) amine (TAEA) to react with the residual chloride groups after the first IP to improve the positive charge intensity of the membrane surface. Compared to the pristine membrane formed after the first IP, the TAEA-optimized membrane exhibited a high pure water permeability (PWP) of 25.2 L m−2 h−1 bar−1 and nearly 90 % rejection to MgCl2 at 2 bar operating pressure. Meanwhile, when treating synthetic electroplating rinse water, the membrane was still able to achieve 85 % rejections to Cu2+ and Ni2+ ions during a 7-day operation test under pH of 1 condition. The results demonstrate the good potential of the membrane for heavy metal ions removal in industrial acidic wastewater.National Research Foundation (NRF)Public Utilities Board (PUB)This research is supported by the National Research Foundation, Singapore, under its Singapore-China Joint Flagship Project (Grant Award #023064-00001).

First-Principles Study on the Stability and STM Image of Borophene
No full textAbstract Very recently, borophene (atomic-thin two-dimensional boron sheet) has been successfully synthesized on the Ag(111) surface by deposition. Two kinds of structures were found. However, the identification of the monolayer boron sheets grown on the metal substrate, as well as the stability of different 2D boron sheets, is controversial. By performing the first-principles calculations, present study investigates the atomic structure, stability, and electronic properties of the most possible boron sheets grown on metal surface, namely, buckled triangular, β12, and χ3 types of crystal lattice. Our result shows that all the three freestanding sheets are thermodynamically unstable and all are metallic. On the other hand, our result indicates the Ag(111) substrate stabilize these sheets. Additionally, our simulated STM images of these monoatomic-thin boron sheets on Ag(111) surface reproduce the experiment observations well and clearly identify the as-grown boron sheets
