Linguistic landscape
Authors: Spolsky Bernard 
Published: March 2020

AbstractThe paper starts with signs that Cooper and I found in the Old City of Jerusalem. It describes how the term Linguistic Landscape was applied to the recollections of francophone high school students of the signs they had seen. It traces the many collections of photos employing digital cameras and cell-phones, and research that was derived from these collections, including published papers and books, a journal, and an annual workshop. The paper regrets the rarity of details of authorship (but reports who was responsible for the Jerusalem street signs), and the tendency to interpret signs without detailing authorship. Signs provide evidence of the state of literacy, but ignore the sociolinguistic make-up of the local community, missing that for earlier scholars “linguistic landscape” meant speech as well as writing. It regrets the paucity of efforts to provide a theory of public signage, arguing that this could be derived from the field of Semiotics.
Tempo and affect in the Linguistic Landscape
Authors: Niedt Greg 
Published: March 2020

Abstract
While the role of time and emotion have been acknowledged in linguistic and semiotic landscapes research, the
particular qualities of tempo and affect have rarely been discussed directly. This case study from an Italian-American festival in
South Philadelphia, a diverse and changing urban neighborhood, demonstrates how the two qualities work together to influence the
discursive construction of identity for residents as they interact with the space. Ethnographic observation and photographs from
the two days of the festival, as well as interviews with locals, frame the discussion of how to explore the landscape through this
lens. The paper encourages researchers to devote more attention to the abstract qualities of landscapes, and serves as a starting
point for critical examinations of a place and the distribution of capital among its occupants.
Diachronic aspects of Bjokapakha epistemic verbal morphology
Authors: Grollmann Selin 
Published: March 2020

AbstractBjokapakha belongs to the Tshangla cluster of the Trans-Himalayan (Tibeto-Burman) language family and is spoken in Central Bhutan. Like many languages of the Himalayan region, Bjokapakha exhibits a rich system of epistemic functions, centering around the notion of personal or subjective knowledge (a.k.a. egophoricity, conjunct-disjunct or mirativity). Morphosyntactically, the epistemic categories of Bjokapakha are expressed by constructions involving combinations of nominalisers and copulas which exhibit varying degrees of grammaticalisation. This paper presents the epistemic categories of Bjokapakha and examines the genesis of the Bjokapakha epistemic verbal system from a comparative perspective drawing on insights from other varieties of the Tshangla cluster. Furthermore, a first reconstruction of the nominalisers and copulas of Proto-Tshangla is proposed. It will become evident that nominalisers and copulas have played a crucial role in the emergence of epistemic verbal morphology of Bjokapakha and still constitute productive means for the grammaticalisation of new epistemic categories.
‘Pour out libation to all the gods!’
Authors: Daudey Henriëtte , Pincuo Gerong 
Published: March 2020

Abstract
Ritual speech in many languages around the world shows grammar distinct from grammar used in daily speech. In Northern
Prinmi ritual speech we found a significant use of two exhaustive constructions, one of which is not attested in daily speech; the other is
only minimally attested. We argue that exhaustive constructions are strong expressions of the utmost degree which makes them particularly
useful to the serious occasions in which ritual speech is used, such as when pronouncing blessings or invoking the gods. We also discuss two
possible grammaticalization pathways, but find no conclusive evidence for either.
Northern Sangtam phonetics, phonology and word list
Authors: Coupe Alexander R. 
Published: March 2020

AbstractThis paper presents a comprehensive phonetic and phonological description of Northern Sangtam, an essentially undescribed Tibeto-Burman language of central Nagaland belonging to the Aoic subgroup. It is a noteworthy language from a number of phonological perspectives, not least because its phoneme inventory contains two of the world’s rarest phonemes: a pre-stopped bilabial trill, and a doubly-articulated labial-coronal nasal. These unique segments are described in detail, and an attempt is made to determine how they might have developed their phonemic status. The tone system is also of interest, as it demonstrates evidence of debuccalization resulting in the development of a new high tone. Following a systematic description of the syllable and word structure, the tone system, and the segmental phonology, some observed age-related differences in the phoneme inventory are discussed. The paper is linked to an online repository containing the audio-visual data and transcribed word lists of approximately 900 items, based on the recorded utterances of eight speakers.
Improved effects of okara atomized by a water jet system on α-amylase inhibition and butyrate production by Roseburia intestinalis
Authors: Nagano Takao , Hirano Rika , Kurihara Shin , Nishinari Katsuyoshi 
Published: March 2020

Abstract
Improving the physicochemical properties of okara for various applications in foods is of great importance. Here, okara and microcrystalline cellulose (MCC) were atomized using a water jet (WJ) system. The WJ-treated okara and MCC dispersed homogeneously in water, and their median sizes in particle size distribution were 6.6 μm and 9.5 μm, respectively. The dispersions of WJ-treated okara and MCC showed high apparent viscosity and shear thinning behavior. Moreover, the inhibition of α-amylase activities by WJ-treated okara was more effective than that by untreated MCC and cellulose. Furthermore, the production of short-chain fatty acids by 32 dominant species of human gut microbes was determined. An increase in butyrate production by Roseburia intestinalis was observed in the presence of WJ-treated okara, but not in untreated okara or WJ-treated MCC. These results demonstrate that WJ system can be used on okara to increase inhibited α-amylase activities and butyrate production by gut microbiota.

Tide-rainfall flood quotient: an incisive measure of comprehending a region’s response to storm-tide and pluvial flooding
Authors: Mohanty Mohit Prakash , Sherly Mazhuvanchery Avarachen , Ghosh Subimal , Karmakar Subhankar 
Published: March 2020

Abstract
It is undeniable that coastal regions worldwide are facing unprecedented damages from catastrophic floods attributable to storm-tide (tidal) and extreme rainfall (pluvial). For flood-risk assessment, although recognizing compound impact of these drivers is a conventional practice, the marginal/individual impacts cannot be overlooked. In this letter, we propose a new measure, Tide-Rainfall Flood Quotient (TRFQ), to quantify the driver-specific flood potential of a coastal region arising from storm-tide or rainfall. A set of inundation and hazard maps are derived through a series of numerical and hydrodynamic flood model simulations comprising of design rainfall and design storm-tide. These experiments are demonstrated on three different geographically diverse flood-affected coastal regions in India. The new measure throws light on existing knowledge gaps on the propensity of coastal flooding induced by the marginal/individual contribution of storm-tide and rainfall. It shall prove useful in rationalizing long-term flood management strategies customizable for storm-tide and pluvial dominated global coastal regions.

Published: March 2020

Abstract
The reverse supply chain has gained increased attention across industries due to the high product return rates. Many strategic and economic benefits can be reaped by efficiently managing the reverse supply chain, such as; cost reduction and enhanced environmental performance. Despite the acknowledgement of the available advantages that can be reaped, there is an overall lack of academic research concerning performance metrics, in particular KPIs (Key Performance Indicators), that can help in managing reverse supply chains. Moreover, industry-specific KPIs have not been explored thoroughly. The apparel industry is currently plagued by high return rates, which suggests that it is even more important for clothing retailers to look over their reverse supply chains. The conceptual framework presented in this report seeks to diminish the gap in literature and provide clothing retailers with KPIs with a focus on environmental sustainability that can help in the decision-making process. The framework is expected to promote sustainability as a more central decision-making criterion within reverse supply chains, especially within the apparel industry.

Published: March 2020

Abstract
In order to obtain the maximum magnetic energy product in the sealing gap of the magnetic fluid sealing structure to improve the pressure capability of the magnetic fluid sealing, based on the magnetic circuit design theory and the magnetic fluid sealing theory, a parallel connection with three magnetic sources is provided. The magnetic fluid seal structure is designed for the magnetic circuit. The magnetic field in the magnetic fluid seal structure is calculated by the finite element method, and the pressure capability of the magnetic fluid seal is calculated. The results are analyzed and discussed. The results show that the magnetic flux leakage at the junction of the pole piece and the permanent magnet and the axial length of the intermediate pole pieces are short, which results in a nonlinear relationship between the magnetic induction strength difference between the two pole pieces and the sealing gap between the two pole pieces. The magnetic circuit method is lower than the magnetic fluid seal pressure capability calculated by the finite element method of the magnetic field.

Published: March 2020

Abstract
The screw drilling tool is an important underground power tool in the oil fields. During the working process, the rotor will be damaged or unevenly worn. The repair and reuse of the damaged area of the rotor will greatly improve the utilization rate of the screw drilling tool and reduce the mining cost. To this end, based on the formation principle of the rotor surface of the five-head screw drill, the curve coordinates are described by the ray length and the rotation angle. The axis relationship equation is characterized by exploring the intrinsic relationship between the two coordinates, and the reverse model of a single screw drill rotor was constructed by point collection. At the same time, the experimental research was carried out to verify the feasibility of modeling the screw drilling tool according to the axial section. In order to provide an effective way to reverse the entire body based on the unworn area of the screw drilling tool, the inverse modeling theory of the spiral surface entity is greatly enriched.

Published: March 2020

Abstract
Steel is widely used as a grounding material in power system, but it is easily corroded in the soil. To resolve the problem a new type of modified concrete composite has been developed. The modified concrete, added with carbon fiber, wrapped around carbon steel to form a composite to reduce the steel corrosion. Three corrosion comparison tests had been taken out. The corrosion test under three different pH soils show that the composite’s internal carbon steel’s corrosion rate is better than zinc-clad steel’s rate in all pH soils, and better than copper’s in soil with pH=5, also better than copper-clad steel’s in soil with pH=9. The typical area soil corrosion test shows that modified concrete can protect carbon steel in saline-alkali soil area and acid red soil area. The results of site-buried test show that modified concrete material can effectively reduce the corrosion of carbon steel in Tianjin saline soil. Those test results show that modified concrete, as external component, can protect internal carbon steel in various environments. The composite’s anti-corrosion effect is better other metals regularly used in grounding. The composite can be used in power system grounding, especially in corrosive areas such as saline-alkali area and acid red area.
