Effect of thermal modification on the micromorphology of decay of hardwoods and softwoods by the white rot fungusPycnoporus sanguineus
Authors: Gao Jie , Kim Jong Sik , Daniel Geoffrey 
Published: June 2018

AbstractThermal modification (TM) of wood at high temperatures can lead to significantly improved decay resistance against white rot (WR) fungi, but little is known about the mechanism of this improvement at the cellular level. As a contribution to this topic, hardwoods (HWs) (ash, beech) and softwoods (SWs) (spruce, fir) were submitted to the Termovuoto®TM process at 220°C for 3–4 h (shortly TMW220°C) and were degraded by the WR fungusPycnoporus sanguineus.The results were studied using microscopy techniques. Decay occurred preferentially via cell wall delignification prior to the removal of cellulose and hemicelluloses. Concerning this effect and fungal colonization, there were no essential differences between TMW220°Cand the unmodified reference of all wood species. TMW220°C, however, showed a number of characteristic changes in decay morphology. Narrow and distinct concentric transition zones were observable in decayed fiber and tracheid cell walls, which demark the lignified and delignified regions. Moreover, cell wall separation by preferential delignification of compound middle lamellae (CML) was not seen in decayed tracheids. It can be concluded that the Termovuoto TMW220°Cprocess has an impact on the delignification process ofP. sanguineusat the cell wall level, which slows down the decay.
Negotiation of meaning and negotiation of form in Chinese EFL classroom discourse
Authors: Wang Qing 
Published: June 2018

AbstractIn recent decades, numerous empirical studies have been conducted on negotiation of meaning and negotiation of form, but few have focused on examining the distinction between the two negotiation types. This qualitative study aims at distinguishing the two negotiation types by analyzing teacher-student dyadic interaction. Three English teachers and their students from a university in China participated in the study. The classroom interaction between the teachers and their students was recorded over 11 weeks, and the data analyzed for the present study totaled 13 hours and 50 minutes. Results indicate that (1) in terms of teacher intentions, the two negotiation types differ considerably: whereas negotiation of meaning is conversational and didactic in function, negotiation of form is solely didactic; (2) regarding retrieval processes and types of learner uptake, the two negotiation types differ slightly except for when negotiation of meaning is didactic in function. The findings thus reveal some issues to address regarding the function of negotiation of meaning.

Abstract
The genus Thyroptera is composed of small insectivorous bats widely distributed in the Neotropics. Thyroptera lavali is an Amazonian species distributed in lowland rainforests of Peru, Ecuador and Brazil and in the Venezuelan Eastern Llanos. The goal of this study was to document new records of T. lavali for Venezuela and update the geographic distribution of Thyroptera species in that country. Based on specimens deposited in Venezuelan museums, we report the first record of T. lavali for the Guiana Shield and the second record for the Venezuelan Llanos. The external and cranial measurements of the analyzed specimens fall within the range previously reported for T. lavali; likewise, the qualitative characters are similar to what is known for the species. Additionally, derived from a search of records in databases, we report the first specimens of Thyroptera discifera for the Orinoco river basin. We confirm the presence of three species in Venezuela: T. discifera, distributed in the Cordillera de la Costa and Central and Western Llanos; Thryoptera tricolor, occurring in the Andes, Deltaic System and the Guiana Shield and T. lavali, recorded in the Eastern Llanos, Deltaic System and the Guiana Shield.

Lost in Translation: Local Relief Provision and Historiographical Imperialism
Authors: Reeves Caroline 
Published: June 2018

Abstract
The historiographical record of charity, both visual and written, has long been appropriated by philanthro-imperialists intent on using material aid to further their own agendas. International actors committed to bringing their own priorities and prerogatives with them overseas have ignored or intentionally erased accounts of local, particularly non-Western, humanitarian and charitable initiatives. In some contexts, local communities have also chosen to erase their own charitable history. This article uncovers one such hidden charitable tradition, that of pre-Maoist China. I discuss indigenous Chinese charitable work and its interplay with Western charitable actors and activities at the turn of the twentieth century, at the height of the New Imperialism (c. 1870–1914) to explore two little-recognized facets of the relationship between charity and imperialism: the erasure of local traditions of charity in the annals of imperialist powers and the importance of language in the preservation and validation of these traditions.
Reconstructing chemical plumes from stand-off detection data of airborne chemicals using atmospheric dispersion models and data fusion
Authors: Björnham Oscar , Grahn Håkan , Brännström Niklas 
Published: June 2018

Abstract
Stand-off detection of airborne chemical compounds has proven to be a useful method that is gaining popularity following technical progress. There are obvious advantages compared to in situ measurements when it comes to the security aspect and the ability to measure at locations otherwise hard to reach. However, an inherent limitation in many of the stand-off detection techniques lies in the fact that the measured signal from a chemical depends nonlinearly on the distance to the detector. Furthermore, the measured signal describes the summation of the responses from all chemicals spatially distributed in the line of sight of the instrument. In other words, the three dimensional extension of the chemical plume is converted into a two-dimensional image. Not only is important geometric information per se lost in this process, but the measured signal strength itself depends on the unknown plume distribution which implies that the interpretation of the observation data suffers from significant uncertainty. In this paper we investigate different and novel approaches to reconstruct the original three-dimensional distribution and concentration of the plume by implementation of atmospheric dispersion models and numerical retrieval methods. In particular our method does not require a priori assumptions on the three-dimensional distribution of the plume. We also strongly advocate the use of proper constraints to avoid unphysical solutions being derived (or post-process ‘adjustments’ to correct unphysical solutions). By applying such a reconstruction method, both improved and additional information is obtained from the original observation data, providing important intelligence to the analysts and decision makers.
A hidden Markov regime-switching smooth transition model
Authors: Elliott Robert J. , Siu Tak Kuen , Lau John W. 
Published: June 2018

AbstractIn this paper, we develop a new class of parametric nonlinear time series models by combining two important classes of models, namely smooth transition models and hidden Markov regime-switching models. The class of models is general and flexible enough to incorporate two types of switching behavior: smooth state transitions and abrupt changes in hidden states. The estimation of the hidden states and model parameters is performed by applying filtering theory and a filter-based expectation-maximization (EM) algorithm. Applications of the model are illustrated using simulated data and real financial data. Other potential applications are mentioned.
Assessment of Support Conditions of Concrete Pavement Using FWD Deflection Basin Data
Authors: Vennapusa Pavana K. R. , Zhang Yang , White David J. 
Published: June 2018

Abstract
Results from a field forensic investigation conducted using a falling weight deflectometer (FWD) and visual observations on a jointed concrete pavement that showed premature distresses are presented in this article. At the time of testing, the pavement was six years old and was supported on a crushed limestone granular base underlain by cohesive natural or fill subgrade. The primary objective of the field investigation was to assess whether the foundation support conditions contributed to the distresses observed. FWD tests were conducted on 140 panels over an 830-m-long section of which 25 panels showed distress. The FWD deflection basin data was used to calculate several index parameters, which showed statistically significant differences between the cracked and the uncracked slabs, which suggests that the foundation layer properties were comparatively weaker under the cracked slabs. Visual observations showed that some of the distresses were related to potential lateral movement of the slopes next to the pavement.
Dynamics of a host-pathogen model with constant mortality rate
Authors: Din Qamar 
Published: June 2018

In this paper, we propose a discrete-time host-pathogen model and study its qualitative behavior. The model is for the spread of an infectious disease with constant mortality rate of hosts. Moreover, the time-step is equal to the duration of the infectious phase and the host mortality is taken at some constant rate d >0. This two-dimensional discrete-time epidemic model has complex dynamical behavior. More precisely, we investigate the existence and uniqueness of positive equilibrium point, boundedness character, local and global asymptotic stability of unique positive equilibrium point, and the rate of convergence of positive solutions that converge to unique positive equilibrium point. Numerical simulations are provided to illustrate our theoretical results.

2018! Transcorridos quase 18 anos do 21º milênio, desigualdades de gênero persistem, exigindo que as lutas continuem, quer no âmbito secular, quer no contexto de diferentes religiões. Lutas, no plural, porque são muitas as frentes, grupos e atorxs que aí se engajam, embora com muitos objetivos em comum. Os artigos deste número da Mandrágora dão evidência da necessidade de avançar ao apontar as assimetrias e lacunas. A começar por aquelas presentes nos próprios Programas de Pós-Graduação em Ciências da Religião no Brasil, a um dos quais está vinculada esta revista, e mesmo nas pesquisas em perspectiva feminista e de gênero produzidas no contexto desses programas, conforme pode-se verificar na detalhada investigação de Clóvis Ecco, Thaís Alves Marinho e Claudete Ribeiro de Araújo, no artigo intitulado “Religião e gênero: uma investigação do estado da arte dos estudos de gênero nos programas de pós-graduação em ciências da religião no Brasil”. Efetuando o mapeamento das dissertações e teses que têm trabalhado questões relativas às desigualdades de gênero (estado da arte), os/as autores/as analisam como as Ciências da Religião no Brasil têm absorvido as principais discussões acerca da categoria nos últimos 17 anos. Na sua análise contemplam também o levantamento dos números de homens e mulheres que compõem o quadro de docentes, discentes e funcionários dos Programas de Pós-Graduação em Ciências da Religião.
