Authors: Assakhiy Rasyada , Anwar Samsul , Fitriana A.R.
Published: June 2020

Baitulmal Aceh merupakan sebuah lembaga pemerintah daerah Provinsi Aceh yang bertanggung jawab sebagai pengelola dan pendistribusi zakat, infak dan sedekah (ZIS). Peramalan potensi zakat pada masa yang akan datang dibutuhkan oleh Baitulmal Aceh sebagai salah satu landasan penyusunan kebijakan pengelolaan ZIS. Penelitian ini bertujuan untuk meramalkan potensi zakat yang terkumpul pada tahun 2018 dan 2019 dengan mempertimbangkan efek dari variasi kalender. Data yang digunakan dalam penelitian ini adalah data realisasi penerimaan zakat bulanan mulai dari bulan Januari 2015 hingga Desember 2017 yang diperoleh dari Baitulmal Aceh. Data tersebut dianalisis dengan model Autoregressive Integrated Moving Average with Exogenous Variable (ARIMAX) dan Seasonal Autoregressive Integrated Moving Average (SARIMA) sebagai model pembanding. Hasil penelitian menunjukkan bahwa model ARIMAX dengan orde ARIMA(2,0,2) (1,0,2)12, t, V1, ..., V11 jauh lebih baik daripada model SARIMA dengan orde ARIMA(0,1,2)(0,1,1)12 berdasarkan indikator ketepatan hasil ramalannya (RMSE dan MAPE). Realisasi penerimaan zakat pada tahun 2018 dan 2019 masing-masing diperkirakan sebesar Rp. 1.347.526.504 dan Rp. 1.359.728.268. Hasil peramalan tersebut dapat digunakan sebagai salah satu rujukan bagi Baitulmal Aceh dalam menyusun kebijakan pendistribusian zakat pada tahun-tahun yang akan datang.

Az oktatási céllal alkalmazott játékok nagyon népszerűek, mivel olyan aktív tanulási környezetet teremtenek, amely alkalmas arra, hogy a tanulók tudását gyarapítsa, készségeit fejlessze, és a tanulók attitűdjére pozitív hatást gyakoroljon. Az oktatási céllal alkalmazott játékok nemzetközi szakirodalma jelentős, mivel ezek a játékok képesek arra, hogy vonzó és interaktív tanulási lehetőségeket teremtsenek, amelyekben a tanulók felfedezhetnek, játszhatnak, probléma-megoldási stratégiákat találhatnak ki és valósíthatnak meg. A téma szakirodalmára jellemző, hogy az elmúlt évtizedekben a már meglévő fogalmakat számos új fogalom egészítette ki, gazdagítva és részletezve a korábbi elméleti keretet. Azonban az újonnan megjelenő fogalmak beillesztése a már meglévő rendszerbe korántsem akadálymentes. Az áttekintésben tárgyalt játékok oktatási célokat szolgálnak. Ezek a célok meghatározzák a játék jellemzőit, típusát. Ahhoz, hogy a játékokat az oktatásban sikeresen alkalmazzák, tudatos felhasználói viselkedésre van szükség. A tudatosság kialakításához pedig szükséges a folyamatosan bővülő elméleti keret alapos ismerete, hiszen ez segít abban, hogy eldöntsük, milyen céllal, melyik játéktípus, melyik koncepció a hatékony. Az oktatási céllal alkalmazott játékok szakirodalmi áttekintésének célja, hogy bemutassuk e játékok definiálásának problémás elemeit, a szakirodalomban megjelenő fogalmak értelmezését és a fogalmak közötti kapcsolatokat. Az áttekintés során kitérünk az edutainment, a komoly játékok, a gamifikáció, a játék-alapú tanulás, a digitális játék-alapú tanulás fogalmak részletesebb, valamint az egyéb kapcsolódó fogalmak rövid bemutatására.

Deciding Among Noninvasive Tools for Predicting Varices Needing Treatment in Chronic Liver Disease: An Analysis of Asian Cohort
Authors: Sharma Sanchit , Agarwal Samagra , Gunjan Deepak , Kaushal Kanav , Anand Abhinav , Saraya Anoop
Published: June 2020

INTRODUCTION:

Both transient elastography (TE)-based and non–TE-based criteria exist for detection of varices needing treatment (VNT) in patients with asymptomatic advanced chronic liver disease (CLD). However, their performance in clinical settings at different risk thresholds of detection of VNT and in regions where elastography is not widely available is unknown. We aimed to validate existing noninvasive criteria in our patients with CLD and identify best TE- and non–TE-based criteria for VNT screening at usual risk thresholds.

METHODS:

Patients with compensated advanced CLD (cACLD) who underwent esophagogastroduodenoscopy and TE within 3 months were included. Diagnostic performance of Baveno VI, expanded Baveno VI, platelet–model for end-stage liver disease, and platelet–albumin (Rete Sicilia Selezione Terapia-hepatitis C virus) criteria were estimated. Decision curve analysis was conducted for different predictors across range of threshold probabilities. A repeat analysis including all patients with compensated CLD (cACLD and non-cACLD) was performed to simulate absence of TE.

RESULTS:

A total of 1,657 patients (cACLD, 895; non-cACLD, 762) related to hepatitis B virus (38.2%), hepatitis C virus (33.4%), nonalcoholic steatohepatitis (14.7%), and alcohol (11.8%) were included. Baveno VI identified maximum VNT (97.3%) and had best negative predictive value (96.9%), followed by platelet–albumin criteria. Expanded Baveno VI and platelet–model for end-stage liver disease had intermediate performance. At threshold probability of 5%, Baveno VI criteria showed maximum net benefit, and platelet–albumin criteria was next best, with need for 95 additional elastographies to detect 1 additional VNT. Similar results were obtained on including all patients with compensated CLD irrespective of TE.

DISCUSSION:

Baveno VI criteria maximizes VNT yield at 5% threshold probability. An acceptable alternative is the platelet–albumin criteria in resource-limited settings.

Published: June 2020

The present study aimed to investigate the effect of feeding fermented mixture of cassava pulp and M. oleifera leaf meal (FCPMO) on the breast meat characteristics of broiler chickens. From day 8 onward, 400 Lohmann broiler chicks were allotted to four dietary groups included CONT (maize-soybean-based feed with no additive), BACI (maize-soybean-based feed supplemented with 0.1% zinc bacitracin), FERM (feed containing 20% of FCPMO) and FERB (feed containing 20% of FCPMO and 0.1% probiotic Bacillus subtilis). At day 35, one male chick from each replicate (10 chicks per treatment group) was taken and slaughtered. After being eviscerated and de-feathered, sample of breast meat was obtained for the assessment of meat characteristics. Results showed that feeding FCPMO had no effect (P>0.05) on pH and water holding capacity (WHC) of breast meats. Compared to other groups, FERB meat had higher (P<0.05) cooking loss. FERM and FERB meats had lower (P<0.05) moisture content than that of CONT and BACI meats. Feeding FCPMO with or without B. subtilis increased (P<0.05) crude protein content of breast meats. Feeding FCPMO resulted in lower (P<0.05) fat content in the breast meat. Compared to other meats, breast meats from BACI had higher (P<0.05) ash content. Cholesterol was lower (P=0.08) in FERB than in BACI and FERM meats. The 2,2-diphenylpicrylhydrazyl (DPPH) IC50 values were higher (P<0.05) in meat of CONT than that in other groups. Feeding FCPMO resulted in higher (P<0.05) polyunsaturated fatty acids (PUFA), lower (P<0.05) monounsaturated fatty acids (MUFA) and had no effect on saturated fatty acids (SFA) contents of broiler breast meats. In conclusion, feeding FCPMO produced healthy broiler meat as reflected by the higher contents of protein, PUFA and antioxidants, and lower fat in meats.
Determinación de emisiones GEI en una matriz energética sustentable mediante análisis de escenarios
Authors: Ramos Sanz Alba Inés
Published: June 2020

Se toma por Caso de estudio una Matriz Energética Sustentable, compuesta en un 85% por recursos energéticos renovables de origen hidroeléctrico, a fin de estimar las emisiones de dióxido de carbono equivalente (CO2eq; GEI) por MWh de energía consumida y Per Cápita. Antecedentes indican que dicha matriz se abastece con frecuencia de una matriz convencional nacional. La prueba de hipótesis confirma este supuesto; la Matriz Energética Sustentable cubre la demanda energética en un 17% de las veces. Se determina el coeficiente de variación para realizar un análisis de escenarios, a fin de observar el comportamiento de las emisiones de CO2eq/Per Cápita según la participación de la Matriz Energética Sustentable, en ocasiones en las cuales no cubre la demanda y debe proveerse con recursos fósiles del Sistema Interconectado Nacional. Se concluye que el nivel medio de emisiones GEI en un 83% de las ocasiones crece hasta cinco veces que el estimado por unidad de energía (0,10 CO2eq/MWh) y hasta ocho veces por usuario (5,20 tnCO2eq/Per Cápita). Esta conclusión alerta sobre los resultados contradictorios en la operación de las matrices energéticas, diversificadas en la búsqueda de una mayor sustentabilidad ambiental.
The Ælfrician Glossaries in Oxford, Bodleian Library, Barlow 35: A New Edition and Commentary
Authors: Cataldi Claudio
Published: June 2020

The present study provides a full edition and commentary of the three glossaries in Oxford, Bodleian Library, Barlow 35, fol. 57r–v. These glossaries, which were first partly edited and discussed by Liebermann (1894), are comprised of excerpts from Ælfric’s Grammar and Glossary arranged by subject. The selection of material from the two Ælfrician works witnesses to the interests of the glossator. The first glossary in Barlow 35 collects Latin grammatical terms and verbs followed by their Old English equivalents. The second glossary is drawn from the chapter on plant names of Ælfric’s Glossary, with interpolations from other chapters of the same work. This glossary also features twelfth-century interlinear notations, which seem to have a metatextual function. The third glossary combines excerpts from Ælfric’s Glossary with verbs derived from the Grammar. Liebermann transcribed only part of the glosses and gave a brief commentary on the glossaries as well as parallels with Zupitza’s (1880) edition of Ælfric’s Grammar and Glossary; hence the need for a new edition, which is provided in the present study, along with a comprehensive discussion of the glossaries and a reassessment of the correspondences concerning their Ælfrician sources.
Preparation and characterization of corn starch/PVA/glycerol composite films incorporated with ε-polylysine as a novel antimicrobial packaging material
Authors: Yurong Gao , Dapeng Li
Published: June 2020

Corn starch/polyvinyl alcohol (PVA)/glycerol composite films incorporated with ε-polylysine were prepared, and their properties were investigated. The Fourier-transform infrared (FTIR) spectroscopy indicated that the interactions happened between the amino group of ε-polylysine and hydroxyl group starch/PVA composite films. X-ray diffraction (XRD) analysis showed that the addition of ε-polylysine decreased the intensity of all crystal peaks. Thermogravimetric (TGA) analysis suggested that ε-polylysine improved the thermal stability of composite films. Scanning electron microscopic (SEM) analysis showed that the upper surface of composite films incorporated with ε-polylysine presented more compact and flat surface. The antimicrobial activity of the composite film progressively increased with the increasing of ε-polylysine concentration (P < 0.05). The tensile strength, elongation at break and water absorption significantly increased, whereas water solubility decreased with the increasing of ε-polylysine concentration (P < 0.05). Therefore, the corn starch/PVA/glycerol composite films incorporated with ε-polylysine had good mechanical, physical and antimicrobial properties and could have potential application as a novel antimicrobial packaging material.

Published: June 2020

Objectives

The improvement in the/reaction time is important, as it is an indicator of cognitive function. Therefore, there is a need, especially for adolescents in the form of techniques or courses that can improve the reaction time. Yoga was found to cause a better improvement in the health of the individuals. The present study intended to show the effects of Bhramari pranayama (Bhr.P) on reaction time in the healthy adolescents.

Methods

Of the 730 potential subjects screened, 520 apparently healthy adolescents randomly assigned to either the Bhr.P group (n-260) or control group (n-260). Bhr.P group practiced the bhramari pranayama for 3 days in a week for 6 months. The Auditory Reaction Time (ART) and the Visual Reaction Time (VRT) were assessed before and after Bhr.P pranayama practice.

Results

Bhr.P group shows significant shortening of response time in both VRT (from 267.13 ± 52.65 to 249.87 ± 39.41 ms) and ART (from 237.42 ± 48.12 to 227.91 ± 34.60 ms) after 6 months of Bhr.P practice. In control group subjects, no such significant changes were found (p > 0.05).

Conclusions

Shortening of RT implies an improvement in the information processing and reflexes. This beneficial effect of Bhr.P on reaction time can be used for improving cognitive function in the adolescents for their academic performances.

Published: June 2020

Background

Due to increasing prevalence of diabetes and associated endothelial dysfunction, this study was carried out to investigate the effects of co-administration of adrenoceptor blockers (prazosin and propranolol) and glibenclamide on plasma biomarkers of endothelial functions in diabetic rats.

Methods

Experiments were carried out on 35 male Wistar rats (170–200 g). They were divided into seven groups (n=5) as follows: normal control, diabetic control, diabetic + glibenclamide (GLB-5mg/kg/day), diabetic+ prazosin (PRZ-0.5 mg/kg/day), diabetic + PRZ + GLB, diabetic + propranolol (PRP-10 mg/kg/day), diabetes + PRP + GLB. Experimental diabetes was induced with streptozotocin (60 mg/kg) and drugs were administered orally for 3 weeks. Blood pressure was measured and animals were sacrificed afterwards. Blood samples were collected by cardiac puncture, and major marker of endothelial functions, nitric oxide derivatives (NOx), as well as superoxide dismutase (SOD) and malondialdehyde (MDA) were measured on the plasma. The aorta was harvested for histological examination. Data were subjected to descriptive statistics and analysed using ANOVA at α
0.05.

Results

There was a significant increase in levels of NOx and SOD, and a decrease in MDA level in diabetic treated groups compared to diabetic control. Mean blood pressure increased in diabetic control and diabetic + GLB group when compared with normal control, while it was mildly reduced in diabetic group treated with PRZ and PRP, and co-administered GLB. More so, Aorta histology was altered in diabetic control groups when compared with normal control and all diabetic treated groups.

Conclusions

Results from this study suggest that PRZ, PRP, and GLB (singly and in combined therapy) could have a restorative effect on endothelial functions in diabetes.
Evaluation of Moroccan microalgae: Spirulina platensis as a potential source of natural antioxidants
Authors: Bellahcen Touria Ould , AAmiri Abderrahmane , Touam Ikram , Hmimid Fouzia , Amrani Abdelaziz El , Cherif Abdelmjid , Cherki Mounia
Published: June 2020

Background

Ethanolic, aqueous and lipidic extracts of Spirulina platensis were evaluated for their bioactive substances (polyphenols and fatty acids) and antioxidant activities using two different assays diphenyl-1-picrylhydrazyl (DPPH) and azino-bis (ethylbenzthiazoline-6- sulfonicacid (ABTS)).

Methods

The phenolic compounds amounts were determined by colorimetric assays and were analyzed by high-performance and liquid chromatography (HPLC) method. The identification of phenolic compounds in the extract was accomplished by comparison of their retention times with those of pure standards. The chemical composition of fatty acids in lipidic extract was determined by GC/FIDs and GC/MS method.

Results

The obtained results revealed that using DPPH, the ethanolic extract recorded the highest activity with (IC50=449 μg/mL ± 83). It was characterized with a high levels of phenolic and flavonoid content 0.33 ± 0.01 mg GAE/g dw and 0.21 ± 0.01 mg quercetin/g dw, respectively. The ethanolic extract showed the presence of caffeic acid, syringic acid, ferulic acid, p-coumaric acid, chlorogenic acid, kaempferol, quercetin and apigenin. Those entire phenolic compounds seem participle synergistically to the pronounced higher activity. To the best of our knowledge, the apigenin (4′, 5, 7,-trihydroxyflavone), a natural compound which is famously known by its potent antiradical activity, was identified for the first time in Moroccan S. platensis only in the ethanolic extract. A high positive correlation (r=0.895) between the antioxidant activity and the chemical composition of ethanolic extract was observed. For ABTS, lipidic extract showed the highest activity with (IC50=740 μg/mL ± 12). A total of 15 fatty acids compounds, amounting 89.73% of the extract were identified. γ-linolenic acid (GLA) (39.02%) and α-linolenic acid (ALA) (13.85%) were the major component and contribute greatly to the antioxidant activity observed. The lipidic extract has a high content of unsaturated fatty acids (70.95%) which are often exhibited very high antioxidant activity since they have two or more double bonds and chain lengths. The aqueous extract either with DPPH or ABTS methods, recorded low antioxidant activity. Its correlation was r=0.499, lower than found in the ethanolic extract.

Conclusions

These results showed that Spirulina platensis could be considered as a valuable source of fatty acids and phenolics with potent antioxidant activity. It may be employed in the manufacture of pharmaceutical drugs as an alternative source of natural antioxidants.
Geometric phase for multidimensional manipulation of photonics spin Hall effect and helicity-dependent imaging

Published: June 2020

The spin Hall effect of light, associated with spin-orbit interactions, describes a transport phenomenon with optical spin-dependent splitting, leading to a plethora of applications such as sensing, imaging, and spin-controlled nanophotonics. Although geometric meatsurfaces can mimic photonic spin Hall effect by spatially splitting left-hand circularly polarized and right-hand circularly polarized states of electromagnetic waves with anomalous refraction or reflection angles, the geometric phase generated by metasurfaces hinders metalenses to realize simultaneous focusing of different spin states, limiting further applications. Here, we propose and experimentally demonstrate an approach to realizing a spin Hall metalens that can focus terahertz waves with different spin states and flexibly manipulate spin-dependent focal points in multiple spatial dimensions based on a pure geometric phase. A dielectric metasurface consisting of micropillars with identical shape and different in-plane orientations is designed to realize the multidimensional manipulation of photonics spin Hall effect in terahertz region. Furthermore, helicity-dependent imaging is demonstrated by the terahertz spin Hall metalens. The uniqueness and robust approach for manipulating spin photons may have a significant impact on designing ultra-compact and multifunctional devices and spin photonics devices.

Published: June 2020

Three-dimensional structure fabrication using discrete building blocks provides a versatile pathway for the creation of complex nanophotonic devices. The processing of individual components can generally support high-resolution, multiple-material, and variegated structures that are not achievable in a single step using top-down or hybrid methods. In addition, these methods are additive in nature, using minimal reagent quantities and producing little to no material waste. In this article, we review the most promising technologies that build structures using the placement of discrete components, focusing on laser-induced transfer, light-directed assembly, and inkjet printing. We discuss the underlying principles and most recent advances for each technique, as well as existing and future applications. These methods serve as adaptable platforms for the next generation of functional three-dimensional nanophotonic structures.
Band gap manipulation of viscoelastic functionally graded phononic crystal
Authors: Bian Zuguang , Yang Shuai , Zhou Xiaoliang , Hui David
Published: June 2020

In this study, band gaps of SH-waves (horizontally polarized shear waves) propagating in a thermal-sensitive viscoelastic matrix are investigated. Metallic films acting as heat sources are periodically embedded into the matrix, which establishes a periodically inhomogeneous thermal field. The homogenous matrix is therefore transformed into functionally gradient phononic crystals (PCs). A three-parameter solid model is employed to describe the viscoelasticity of the present matrix. By virtue of a transfer matrix method incorporated within a laminated model, the dispersion equation of SH-waves is finally obtained, from which the band gaps are determined. The transmission spectra of a finite-periodic PC are also solved to validate the band gaps. In numerical examples, the influences of incident angles of SH-waves and viscoelasticity of matrix on band gaps are discussed first. Then the research focuses on the means to tune the band gaps by manipulating the inputted powers of heat sources. Numerical examples demonstrate that such a strategy is effective and convenient in tuning the positions and widths of band gaps. A viscous parameter, i.e., the ratio of initial-state to final-state storage moduli, significantly affects the band locations and bandwidths, while the locations of low-order band gaps hardly move with the incident angle of SH-waves. Band gaps of several orders are expected to locate in lower-frequency domain, and the total bandwidth becomes larger as the inputted heat flux increases. This paper lays theoretical foundation to manufacture viscoelastic functionally graded PCs which can be used in frequency-selective devices.

This study examined the coping strategies of crop farmers to pastoralist activities in Odo-Otin Local Government Area of Osun State, Nigeria. A multistage sampling technique was used to select 120 farmers. The data were collected using a well-structured questionnaire and interview and were analysed using descriptive and inferential statistical tools. The result revealed various levels of damage caused to food security by the pastoralist as follows: compaction of soil (84%), damage and eating of the crops on the field (79%), indiscriminate bush burning leading to fire outbreak on farms (73%), stealing of farm produce by herders (73%), pollution of water points (54%), killing of farmers (13%) and others. The result further revealed the coping strategies used by crop farmers: praying for peace (98%), early harvesting (95%), early planting (92%), multiple farm plots (91%), group farming (90%), relocating farm (77%), police intervention (60%), government intervention (9%), NGO intervention (9%) and insurance (4.2%). The results of Chi-square analysis showed that there is a significant relationship between the educational status (X2= 13.06,P= 0.01) and coping strategies used against pastoralist activities. Therefore, it is recommended that the government should formulate a policy that will stimulate peace among crop farmers and pastoralist to sustain food security and reduce poverty among rural dwellers, thereby transforming the rural environment into an attractive centre.
Deictic Shifting in Greek Contractual Writing (I–IV AD)
Authors: Bentein Klaas
Published: June 2020

Much attention has been paid to ‘deictic shifts’ in Ancient Greek literary texts. In this article I show that similar phenomena can be found in documentary texts. Contracts in particular display unexpected shifts from the first to the third person orvice versa. Rather than constituting a narrative technique, I argue that such shifts should be related to the existence of two major types of stylization, called the ‘objective’ and the ‘subjective’ style. In objectively styled contracts, subjective intrusions may occur as a result of the scribe temporarily assuming himself to be the deictic center, whereas in subjectively styled contracts objective intrusions may occur as a result of the contracting parties dictating to the scribe, and the scribe not modifying the personal references. There are also a couple of texts which display more extensive deictic alter­nations, which suggests that generic confusion between the two major types of stylization may have played a role.

Ältere Erwerbstätige in der digitalisierten Arbeitswelt – Ergebnisse der lidA-Studie
Authors: Hasselhorn Hans Martin
Published: June 2020

Aktuelle Analysen der deutschen lidA-Studie (www.lida-studie.de) legen nahe, dass die Digitalisierung der Arbeitswelt bei Älteren noch vornehmlich auf traditionelle digitale Arbeitsmittel beschränkt ist. Sie fühlen sich dabei allermeist sicher und sind zufrieden mit der digitalen Ausstattung. Besondere Risikogruppen für „digitalen Stress“ sind möglicherweise Berufsgruppen, die mit Menschen arbeiten. Aussagekräftige Zahlen sind vonnöten, um die Digitalisierung des Arbeitsalltags zu quantifizieren, Auswirkungen zu beschreiben und Risikogruppen zu identifizieren.
Arbeitsbezogene Ressourcen und Wohlbefinden
Authors: Gusy Burkhard , Lesener Tino , Wolter Christine
Published: June 2020

Positive Konzepte des Wohlbefindens werden auch im Arbeitskontext verstärkt diskutiert – insbesondere Arbeitszufriedenheit und -engagement. In unserem metaanalytischen Review gingen wir der Frage nach, ob sich diese positiven Facetten arbeitsbezogenen Wohlbefindens fördern lassen und welche Merkmale der Tätigkeit (Ressourcen) dazu beitragen. Sowohl Arbeitsengagement als auch Arbeitszufriedenheit lassen sich durch tätigkeitsbezogene Ressourcen steigern, für Arbeitszufriedenheit sind soziale Ressourcen bedeutsamer als für Arbeitsengagement.
Contemporary Art Practice and Indigenous Knowledge
Authors: McMaster Gerald
Published: June 2020

Indigenous artists are introducing traditional knowledge practices to the contemporary art world. This article discusses the work of selected Indigenous artists and relays their contribution towards changing art discourses and understandings of Indigenous knowledge. Anishinaabe artist Norval Morrisseau led the way by introducing ancient mythos; the gifted Carl Beam enlarged his oeuvre with ancient building practices; Peter Clair connected traditional Mi'kmaq craft and colonial influence in contemporary basketry; and Edward Poitras brought to life the cultural hero Coyote. More recently, Beau Dick has surprised international art audiences with his masks; Christi Belcourt’s studies of medicinal plants take on new meaning in paintings; Bonnie Devine creates stories around canoes and baskets; Adrian Stimson performs the trickster/ruse myth in the guise of a two-spirited character; and Lisa Myers’s work with the communal sharing of food typifies a younger generation of artists re-engaging with traditional knowledge.
Marianne Nicolson’s Land-Based KnowledgescapeCliff Painting
Authors: Grunewald Amina
Published: June 2020

Indigenous epistemologies and ontologies are connected to tribal lands, resilience, and claims for sovereignty. These ways of knowing offer an indispensable resource for Indigenous communities in surviving and resisting assimilationist policies. Modes of Indigenous knowledge are not only discussed in academia and practiced in local spaces but are also integrated into artworks that promote public access to First Nations political agendas within settler nation states. Knowledgescapes can be created as conversive artscapes. They can be placed translocally but also re-integrated into First Nations lands. A reworking of the land as a tribally marked space can be traced in artworks that attack bio- and geopolitical manners of settler societies. The land-marker, place-maker, and artscapeCliff Painting(1998) by Marianne Nicolson shall serve as an exemplification of a specific knowledgescape – created for Indigenous audiences to support their claims, and for non-Indigenous audiences to open up a dialogue on colonial issues within a step-by-step decolonizing discourse.
The ‘Fast Runner’ Trilogy, Inuit Cultural Memory, and Knowledge (Re-)Production
Authors: Kilbourn Russell J.A.
Published: June 2020

This paper reads the Isuma ‘Fast Runner’ trilogy –Atanarjuat, The Fast Runner(2001),The Journals of Knud Rasmussen(2006),Before Tomorrow(2008) – as contemporary digital video instantiations of Inuit cultural memory and knowledge (re-)production; as fixed audiovisual texts ironically documenting and archiving a repertoire of traditional cultural folkways, reinscribing them in the present as still-living cultural practices. This is achieved in the films through Isuma’s unique approach to cinematic style, combining long takes and natural light with the freedom and unpredictability afforded by the digital format. In the end, Isuma’s openness to post-literate media forms emerges as an ideal approach to the representation of specific posthuman Indigenous identities.
The geometry relaxation and photodeactivation from the S2 state of dibenzofuran studied by ultrafast spectroscopy
Authors: Wang Lian , Zhang Song , Wang Ye , Zhang Bing
Published: June 2020

Dibenzofuran (DBF) has attracted much attention from scientists recently since it is applied as a photoluminescence material and pharmaceutically active compound. Since the polychlorinated derivatives are highly toxic and manifest photostability in the environment. Femtosecond transient absorption spectroscopy associated with quantum chemical calculations are employed to investigate the ultrafast excited state dynamics of dibenzofuran from the S2 state in 1,4-dioxane and ethanol, respectively. Following excitation at a wavelength of 266 nm, the S2 state is firstly populated in the Franck–Condon region and preserves the planar molecular structure of the ground state. The observed increase of the transient absorption spectra of the excited state within the first several picoseconds indicates a geometry relaxation occurring on the S2 potential energy surface. The subsequent kinetic traces of excited state absorption show that the S2 state in the adiabatic region decays to the S1 state through a fast internal conversion, followed by intersystem crossing to the T1 state with a decay time of tens and hundreds of picoseconds in ethanol and 1,4-dioxane, respectively. Finally, the deactivation processes from the S1 or T state are slow and take place on a time scale of about 20 ns.
Ground-penetrating radar survey at Falerii Novi: a new approach to the study of Roman cities
Authors: Verdonck Lieven , Launaro Alessandro , Vermeulen Frank , Millett Martin
Published: June 2020

Our understanding of Roman urbanism relies on evidence from a few extensively investigated sites, such as Pompeii and Ostia, which are unrepresentative of the full variety of Roman towns. This article presents the results of the first high-resolution GPR survey of a complete Roman town—Falerii Novi, in Lazio, Italy. The authors review the methods deployed and provide an overview of the results, including discussion of a case-study area within the town. They demonstrate how this type of survey has the potential to revolutionise archaeological studies of urban sites, while also challenging current methods of analysing and publishing large-scale GPR datasets.

Published: June 2020

The recent renovation of a house in Chajul in western Guatemala has revealed an unparalleled set of wall paintings, most probably from the Colonial period (AD 1524–1821). The iconography of the murals combines pre-Columbian elements with imported European components in a domestic rather than a religious setting, making them a unique example of Colonial-period art. Here, the authors present the results of iconographic, chemical and radiocarbon analyses of the Chajul house paintings. Dating to the seventeenth to eighteenth centuries AD, the paintings may be connected to a revival of the local religious organisation (cofradías) in the context of waning Spanish colonial control.
Experimental Study of Sealing Performance Test Methods and Sealing Mechanism of Shield Tail Sealing Grease
Authors: Li Xiangqian , Yang Yuyou
Published: June 2020

Throughout this research, five different types of sealing grease samples were collected from the construction sites of shield tunnels and tested with the current sealing test methods. For the purpose of assessing the sealing performance more accurately, a new test method was proposed based on the test results. Through this test method, the maximum diameter of pores (MDPs) that can be blocked by sealing grease was considered as the indicator of sealing performance. Furthermore, it was found that sealing grease basically seals the micropores by forming a sealing layer. If the sizes of the micropores exceeded the MDP, the sealing grease was observed to be leaking until the seal barrier was penetrated by pressure. The MDP is not affected by pressure or time. Through the microscopic images, it was observed that the thickness of the sealing layer increased with the sizes of the micropores. The new test method was used to test the samples of prepared sealing grease with varied fiber contents and it was found that sealing performance improved with increase in fiber content while simultaneously filtration decreased.
