Authors: Hosseinian Hamed , Hosseini Samira , Martinez-Chapa Sergio O. , Sher Mazhar
Published: January 2022

In recent years, wearable contact lenses for medical applications have attracted significant attention, as they enable continuous real-time recording of physiological information via active and noninvasive measurements. These devices play a vital role in continuous monitoring of intraocular pressure (IOP), noninvasive glucose monitoring in diabetes patients, drug delivery for the treatment of ocular illnesses, and colorblindness treatment. In specific, this class of medical devices is rapidly advancing in the area of drug loading and ocular drug release through incorporation of electrospun fibers. The electrospun fiber matrices offer a high surface area, controlled morphology, wettability, biocompatibility, and tunable porosity, which are highly desirable for controlled drug release. This article provides an overview of the advances of contact lens devices in medical applications with a focus on four main applications of these soft wearable devices: (i) IOP measurement and monitoring, (ii) glucose detection, (iii) ocular drug delivery, and (iv) colorblindness treatment. For each category and application, significant challenges and shortcomings of the current devices are thoroughly discussed, and new areas of opportunity are suggested. We also emphasize the role of electrospun fibers, their fabrication methods along with their characteristics, and the integration of diverse fiber types within the structure of the wearable contact lenses for efficient drug loading, in addition to controlled and sustained drug release. This review article also presents relevant statistics on the evolution of medical contact lenses over the last two decades, their strengths, and the future avenues for making the essential transition from clinical trials to real-world applications.

The aim of the present study was to evaluate the use of collagen, elastin, or chitosan biomaterial for bone reconstruction in rats submitted or not to experimental alcoholism. Wistar male rats were divided into eight groups, submitted to chronic alcohol ingestion (G5 to G8) or not (G1 to G4). Nasal bone defects were filled with clot in animals of G1 and G5 and with collagen, elastin, and chitosan grafts in G2/G6, G3/G7, and G4/G8, respectively. Six weeks after, all specimens underwent radiographic, tomographic, and microscopic evaluations. Bone mineral density was lower in the defect area in alcoholic animals compared to the abstainer animals. Bone neoformation was greater in the abstainer groups receiving the elastin membrane and in abstainer and alcoholic rats receiving the chitosan membrane (15.78 ± 1.19, 27.81 ± 0.91, 47.29 ± 0.97, 42.69 ± 1.52, 13.81 ± 1.60, 18.59 ± 1.37, 16.54 ± 0.89, and 37.06 ± 1.17 in G1 to G8, respectively). In conclusion, osteogenesis and bone density were more expressive after the application of the elastin matrix in abstainer animals and of the chitosan matrix in both abstainer and alcoholic animals. Chronic alcohol ingestion resulted in lower bone formation and greater formation of fibrous connective tissue.

Authors: Martins Carla I. , Gil Vitória , Rocha Sara
Published: January 2022

This research addresses the importance of pine wood sawdust granulometry on the processing of medium-density polyethylene (MDPE)/wood composites by rotational molding and its effects on the morphological, mechanical and aesthetical properties of parts, aiming to contribute for the development of sustainable wood polymer composites (WPC) for rotational molding applications. Pine wood sawdust was sieved (<150, 150, 300, 500, 710, >1000 µm) and analyzed for its physical, morphological and thermal characteristics. Rotational molded parts were produced with matrix/wood ratios from 90/10 to 70/30 wt% considering different wood granulometries. As a natural material, wood changed its color during processing. Granulometries below 500 µm presented better sintering, homogeneity and less part defects. Furthermore, 300–500 µm favored the impact resistance (1316 N), as irregular brick-shaped wood was able to anchor to PE despite the weak interfacial adhesion observed. The increase of wood content from 10 to 30% reduced the impact properties by 40%, as a result of a highly porous structure formed, revealing sintering difficulties during processing. WPC parts of differentiated aesthetics and functionalities were achieved by rotational molding. A clear relationship between wood granulometry and WPC processing, structure and properties was identified.

Published: January 2022

Energy demand and the use of commodity consumer products, such as chemicals, plastics, and transportation fuels, are growing nowadays. These products, which are mainly derived from fossil resources and contribute to environmental pollution and CO2 emissions, will be used up eventually. Therefore, a renewable inexhaustible energy source is required. Plant biomass resources can be used as a suitable alternative source due to their green, clean attributes and low carbon emissions. Lignin is a class of complex aromatic polymers. It is highly abundant and a major constituent in the structural cell walls of all higher vascular land plants. Lignin can be used as an alternative source for fine chemicals and raw material for biofuel production. There are many chemical processes that can be potentially utilized to increase the degradation rate of lignin into biofuels or value-added chemicals. In this study, two lignin degradation methods, CuO–NaOH oxidation and tetramethyl ammonium hydroxide (TMAH) thermochemolysis, will be addressed. Both methods showed a high capacity to produce a large molecular dataset, resulting in tedious and time-consuming data analysis. To overcome this issue, an unsupervised machine learning technique called principal component analysis (PCA) is implemented.

Published: January 2022

Poly(hydroxybutyrate-co-3-hexanoate) (PHBH) is a biodegradable thermoplastic polyester with the potential to be used in textile and medical applications. We have aimed at developing an upscalable melt-spinning method to produce fine biodegradable PHBH filaments without the use of an ice water bath or offline drawing techniques. We have evaluated the effect of different polymer grades (mol% 3-hydroxy hexanoate, molecular weight etc.) and production parameters on the tensile properties of melt-spun filaments. PHBH monofilaments (diameter < 130 µm) have been successfully melt-spun and online drawn from three different polymer grades. We report thermal and rheological properties of the polymer grades as well as morphological, thermal, mechanical, and structural properties of the melt-spun filaments thereof. Tensile strengths up to 291 MPa have been achieved. Differences in tensile performance have been correlated to structural differences with wide-angle X-ray diffraction and small-angle X-ray scattering. The measurements obtained have revealed that a synergetic interaction of a highly oriented non-crystalline mesophase with highly oriented α-crystals leads to increased tensile strength. Additionally, the effect of aging on the structure and tensile performance has been investigated.

Published: January 2022

The effect of novel antimicrobial peptides (AMPs) and antimicrobial peptide microspheres (AMS) on the physicochemical and microbial quality of Tricholoma matsutake wild edible mushrooms was investigated. In the experiments, 1.0 g/L, 0.5 g/L of AMS, and 1.0 g/L AMPs were used as preservatives. Mushrooms coated with 1.0 g/L and 0.5 g/L of AMS as a preservative had better physicochemical and sensory qualities than did mushrooms coated with 1.0 g/L of AMPs. In the experiment, 1.0 g/L of blank microspheres without cathelicidin-BF-30 (PLGA-1.0) and distilled water was used as the control. Samples with these two treatments had minimal changes in texture, weight loss, total bacteria count, and sensory attributes. Research results suggests that the use of AMS can maintain the quality of Tricholoma matsutake wild edible mushrooms and could extend the postharvest life to 20 d.
Oligocat: Oligoesters as Pseudo-Homogenous Catalysts for Biodiesel Synthesis

Published: January 2022

Biodiesel production from first-generation feedstock has shown a strong correlation with the increase in deforestation and the necessity of larger areas for land farming. Recent estimation from the European Federation for Transport and Environment evidenced that since the 2000s decade, an area equal to the Netherlands was deforested to supply global biodiesel demand, mainly originating from first-generation feedstock. Nevertheless, biodiesel is renewable, and it can be a greener source of energy than petroleum. A promising approach to make biodiesel independent from large areas of farming is to shift as much as possible the biodiesel production chain to second and third generations of feedstock. The second generation presents three main advantages, where it does not compete with the food industry, its commercial value is negligible, or none, and its usage as feedstock for biodiesel production reduces the overall waste disposal. In this manuscript, we present an oligomeric catalyst designed to be multi-functional for second-generation feedstock transesterification reactions, mainly focusing our efforts to optimize the conversion of tallow fat and sauteing oil to FAME and FAEE, applying our innovative catalyst. Named as Oligocat, our catalyst acts as a Brønsted-Lowry acid catalyst, providing protons to the reaction medium, and at the same time, with the course of the reaction, it sequesters glycerol molecules from the medium and changes its physical phase during the transesterification reaction. With this set of properties, Oligocat presents a pseudo-homogenous behavior, reducing the purification and separation steps of the biodiesel process production. Reaction conditions were optimized applying a 42 factorial planning. The output parameter evaluated was the conversion rate of triacylglycerol to mono alkyl esters, measured through gel permeation chromatography (GPC). After the optimization studies, a conversion yield of 96.7 (±1.9) wt% was achieved, which allows classifying the obtained mono alkyl esters as biodiesel by ASTM D6751 or EN 14214:2003. After applying the catalyst in three reaction cycles, Oligocat still presented a conversion rate above 96.5 wt% and as well an excellent recovery rate.

Published: January 2022

Interpenetrating polymer networks (IPNs) represent an interesting approach for tuning the properties of silicone elastomers due to the possible synergism that may occur between the networks. A new approach is presented, which consists of mixing two silicone-based networks with different crosslinking pathways; the first network being cured by condensation route and the second network by UV curing. The networks were mixed in different ratios and the resulted samples yield good mechanical properties (improved elongations, up to 720%, and Young’s modulus, 1 MPa), thermal properties (one glass transition temperature, ~−123 °C), good dielectric strength (~50 V/μm), and toughness (63 kJ/m3).

Published: January 2022

Hydrogels are highly hydrophilic polymers that have been used in a wide range of applications. In this study, we prepared PVA–CS/SA–Ca2+ core–shell hydrogels with bilayer space by cross-linking PVA and CS to form a core structure and chelating SA and Ca2+ to form a shell structure to achieve multiple substance loading and multifunctional expression. The morphology and structure of core–shell hydrogels were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The factors affecting the swelling properties of the hydrogel were studied. The results show that the PVA–CS/SA–Ca2+ hydrogel has obvious core and shell structures. The SA concentration and SA/Ca2+ cross-linking time show a positive correlation with the thickness of the shell structure; the PVA/CS mass ratio affects the structural characteristics of the core structure; and a higher CS content indicates the more obvious three-dimensional network structure of the hydrogel. The optimal experimental conditions for the swelling degree of the core–shell hydrogel were an SA concentration of 5%; an SA/Ca2+ cross-linking time of 90 min; a PVA/CS mass ratio of 1:0.7; and a maximum swelling degree of 50 g/g.
Molecule Dynamics Simulation of the Effect of Oxidative Aging on Properties of Nitrile Rubber
Authors: Yang Jinsong , Lou Weitao
Published: January 2022

The effects of oxidative aging on the static and dynamic properties of nitrile rubber at the molecular scale were investigated by molecular dynamics simulation. The aged nitrile rubber models were constructed by introducing hydroxyl groups and carbonyl groups into rubber molecular chains to mimic oxidative aging. The static and dynamic properties of the unaged and aged nitrile rubber under different conditions were evaluated by mean square displacement, self-diffusion coefficients, hydrogen bond, fractional free volume, radial distribution function, cohesive energy density and solubility parameter. The results show that the elevated temperature intensified significantly the mobility of rubber molecular chains and fractional free volume, while the compressive strain displayed the opposite effect resulting in packing and rearrangement of rubber chains. The introduction of hydroxyl groups and carbonyl groups enhanced the polarity, intermolecular interactions, the volume and rigidity of molecular chains, implying weaker mobility of molecular chains as compared to unaged models. The compressive strain and oxidative aging both decreased the fractional free volume, which inhibited gaseous and liquid diffusion into the rubber materials, and slowed down the oxidative aging rate. This study provides insights to better understand the effect of molecular changes due to oxidative aging on the structural and dynamic properties of rubber materials at the molecular level.

Published: January 2022

In this work, a Zn–benzenetricarboxylic acid (Zn@H3BTC) organic framework coated with a dispersed layer of chitosan (CH/Zn@H3BTC) was synthesized using a solvothermal approach. The synthesized CH/Zn@H3BTC was characterized by Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscope (FESEM), thermal gravimetric analysis (TGA), and Brunauer, Emmett, and Teller (BET) surface area. The microscopic observation and the analysis of the BET surface area of CH/Zn@H3BTC nanocomposites indicated that chitosan plays an important role in controlling the surface morphology and surface properties of the Zn@H3BTC. The obtained findings showed that the surface area and particle size diameter were in the range of 80 m2 g−1 and 800 nm, respectively. The corrosion protection characteristics of the CH/Zn@H3BTC composite in comparison to pristine chitosan on duplex steel in 2.0 M H2SO4 medium determined by electrochemical (E vs. time, PDP, and EIS) approaches exhibited that the entire charge transfer resistance of the chitosan- and CH/Zn@H3BTC-composite-protected films on the duplex steel substrate was comparatively large, at 252.4 and 364.8 Ω cm2 with protection capacities of 94.1% and 97.8%, respectively, in comparison to the unprotected metal surface (Rp = 20.6 Ω cm2), indicating the films efficiently protected the metal from corrosion. After dipping the uninhabited and protected systems, the surface topographies of the duplex steel were inspected by FESEM. We found the adsorption of the CH/Zn@H3BTC composite on the metal interface obeys the model of the Langmuir isotherm. The CH/Zn@H3BTC composite revealed outstanding adsorption on the metal interface as established by MD simulations and DFT calculations. Consequently, we found that the designed CH/Zn@H3BTC composite shows potential as an applicant inhibitor for steel protection.

Published: January 2022

Denture stomatitis is a multifactorial pathological condition of the oral mucosa that affects up to 72% of denture wearers. It is commonly seen on the palatal mucosa and characterized by erythema on the oral mucosa that are in contact with the denture surface. The aim of this study was to incorporate 2-methacryloyloxyethyl phosphorylcholine (MPC) and dimethylaminohexadecyl methacrylate (DMAHDM) into a high impact polymethylmethacrylate heat-cured denture base acrylic resin as a potential treatment for denture stomatitis. We used a comparative study design to examine the effect of incorporating MPC as a protein repellent agent and DMAHDM as an antifungal agent to prevent the adherence of Candida albicans to the denture base material. The dual incorporation of MPC and DMAHDM reduced C. albicans biofilm colony-forming unit by two orders of magnitude when compared to the control group devoid of the bioactive agents. Although the addition of MPC and DMAHDM alone or in combination significantly reduced the flexural strength of the material, they showed reduced roughness values when compared to control groups. This new denture acrylic resin provides the benefit of enhancing C. albicans biofilm elimination through dual mechanisms of action, which could potentially reduce the prevalence of denture stomatitis.

Published: January 2022

Solid supports functionalized with molecular metal catalysts combine many of the advantages of heterogeneous and homogeneous catalysis. A (NNN)Ru-incorporated porous organic polymer (POP-bp/bbpRuCl3) exhibited high catalytic efficiency and broad functional group tolerance in the C–C cross-coupling of secondary and primary alcohols to give β-alkylated secondary alcohols. This catalyst demonstrated excellent durability during successive recycling without leaching of Ru which is ascribed to the strong binding of the pincer ligands to the metal ions.

Published: January 2022

In this study, a novel polystyrene-block-quaternized polyisoprene amphipathic block copolymer (PS-b-PIN) is derived from anionic polymerization. Quaternized polymers are prepared through post-quaternization on a functionalized polymer side chain. Moreover, the antibacterial activity of quaternized polymers without red blood cell (RBCs) hemolysis can be controlled by block composition, side chain length, and polymer morphology. The solvent environment is highly related to the polymer morphology, forming micelles or other structures. The polymersome formation would decrease the hemolysis and increase the electron density or quaternized groups density as previous research and our experiment revealed. Herein, the PS-b-PIN with N,N-dimethyldodecylamine as side chain would form a polymersome structure in the aqueous solution to display the best inhibiting bacterial growth efficiency without hemolytic effect. Therefore, the different single-chain quaternized groups play an important role in the antibacterial action, and act as a controllable factor.

Published: January 2022

In this paper, an original method of synthesis of Coil-Brush amphiphilic polystyrene-b-(polyglycidol-g-polyglycidol) (PS-b-(PGL-g-PGL)) block copolymers was developed. The hypothesis that their hydrophilicity and micellization can be controlled by polyglycidol blocks architecture was verified. The research enabled comparison of behavior in water of PS-b-PGL copolymers and block–brush copolymers PS-b-(PGL-g-PGL) with similar composition. The Coil-Brush copolymers were composed of PS-b-PGL linear core with average DPn of polystyrene 29 and 13 of polyglycidol blocks. The DPn of polyglycidol side blocks of coil–b–brush copolymers were 2, 7, and 11, respectively. The copolymers were characterized by 1H and 13C NMR, GPC, and FTIR methods. The hydrophilicity of films from the linear and Coil-Brush copolymers was determined by water contact angle measurements in static conditions. The behavior of Coil-Brush copolymers in water and their critical micellization concentration (CMC) were determined by UV-VIS using 1,6-diphenylhexa-1,3,5-trien (DPH) as marker and by DLS. The CMC values for brush copolymers were much higher than for linear species with similar PGL content. The results of the copolymer film wettability and the copolymer self-assembly studies were related to fraction of hydrophilic polyglycidol. The CMC for both types of polymers increased exponentially with increasing content of polyglycidol.

Published: January 2022

This present study concerns refugees and asylum seekers who have been referred to a Mobile Mental Health Unit (MMHU-Ch) in rural Greece on a Northeast Aegean Island during the refugee crisis in 2015. Our objective is the examination and recording of psychopathology characteristics’, the presentation of the therapeutic interventions provided, and the difficulties. The sample is composed of 418 requests made by refugees, asylum seekers, adults, and children. The clinical and demographic data have been gathered from the MMHU-Ch’s charts. The study is retrospective, descriptive with quantitative and categorical variables. The data has been analyzed with the utilization of SPSS. The dominant diagnosis in children involves anxiety disorders, developmental disorders, and PTSD. One noteworthy finding is the high percentage of suicide behavior regardless of psychiatric diagnosis, which should be further examined. As far as interventions are concerned, the conclusions which have arisen are the gradually stronger commitment of the referents, but also the high percentage of requests that dropped out. Further examination of the interventions and their efficiency is recommended as well as probing the features of psychopathology in the long term with a view to clarifying the patronizing and aggravating factors.

Authors: Muşkara Üftade , Konak Ayşin
Published: January 2022

Kendale Hecala is located on the Ambar River in the Upper Tigris Basin, province of Diyarbakır in Southeast Anatolia. Various raw materials, including obsidian, radiolarite, chert, jasper, chalcedony, and quartzite, were used in the lithic industry. Obsidian artefacts constitute an average of 64% of the chipped stone assemblage. Technological analysis reveals that obsidian was brought to the settlement as nodules and chipped into various tools at the settlement. Understanding the operational sequence of the lithic industry, chaîne opératoire, including the distribution of raw material from source to site, is important to demonstrate the socio-cultural organization of the settlement in Southeastern Anatolia during the Ubaid period. In order to identify source varieties, the obsidian artefacts uncovered from Ubaid layers of Kendale Hecala were analyzed by macro-observations, and the characterization of archaeological samples was performed using a handheld XRF. Multivariate analysis of the data indicates the use of obsidian from different resources at the settlement, including Nemrut Dağ, Bingöl B, and Group 3d.
The Rearrangement of Alkylallenes to 1,3-Dienes
Authors: Al-Jawaheri Yassir , Kimber Marc Colin
Published: January 2022

1,3-Dienes are vital building blocks in organic synthesis. They underpin many fundamental synthetic transformations and are present in numerous natural products and drug candidate molecules. The rearrangement of an alkylallene to a 1,3-diene is an atom efficient, redox neutral, transformation that provides a straightforward synthetic route to functionalized 1,3-dienes. Herein, we provide an account of this transformation using allenes that are not predisposed by the presence of heteroatoms or electron-withdrawing groups directly attached to the allene. Early reports of this skeletal rearrangement are acid-mediated approaches, with limited substrate scope, but they provide valuable mechanistic insights. More recent transition metal-mediated approaches that exhibit improved substrate scope are described, together with isolated examples that have utilized this rearrangement.
Presbyterians, Forgiveness, and Dealing with the Past in Northern Ireland: Towards Gracious Remembering
Authors: Ganiel Gladys , Yohanis Jamie
Published: January 2022

The transformative potential of forgiveness has been lauded in theory but its outworking on the ground has proved more challenging. Drawing on a study with 122 Presbyterians in post-violence Northern Ireland, this article returns to debates on forgiveness. We propose a modest role for religious discourses on forgiveness, situated within a wider process of political forgiveness. We advance ‘gracious remembering’ as a contextual, faith-based, transitional concept for helping create conditions in which political forgiveness may become more likely. Drawing on our empirical study, as well as the work of Northern Irish public theologian Johnston McMaster, gracious remembering is orientated around a vernacular understanding of grace and utilizes a four-fold framework to guide grassroots and civil society dialogues about the past: (1) the rehumanizing of the other by acknowledging the human cost of violence, (2) giving victims a public voice, (3) engaging in self-critical reflection, and (4) listening to alternative interpretations of events. Overall, we seek to demonstrate that religious discourses and social scientific framings of political forgiveness need not be opposed; and forgiveness and remembering need not be opposed. Ultimately, we argue for the value of faith-based contributions in post-violence settings, but with ample recognition of their limitations.
How Does the Catholic Clergy Influence What Poles in the UK Know and Think about Brexit?
Authors: Wodka Marek , Fel Stanislaw , Zarzycka Beata , Kozak Jaroslaw
Published: January 2022

Religion can determine how people perceive socio-political reality, especially in a cultural context in which religious affiliation is an important part of national identity. This has a special significance in the Polish cultural context, in which Catholicism is considered the national religion, and its institutional dimension plays an important role in the Polish socio-political domain. The purpose of this study is to analyse how religion affects the socio-political attitudes of Poles abroad. This analysis focuses directly on evaluating the influence of the spiritual leaders of Polish community organisations in the UK on the knowledge and opinions of Brexit among Polish post-accession emigrants to the UK. The study was conducted on a sample of 620 Poles living in the UK (62.6% male) using a group-administered questionnaire. The study found that the Polish Catholic clergy did not play an important role in opinion-forming, i.e., in shaping what Polish emigrants to the UK know and think about Brexit. What proved to be the most powerful factor in terms of opinion-making was the British mass media. The influence of the Catholic clergy on the knowledge of—and opinions on—Brexit among Polish emigrants was only evident among elderly people who did not know English very well, and who regularly participated in religious activities.
Religiosity and Spirituality of German-Speaking Pilgrims on the Way of St. James
Authors: Lienau Detlef , Huber Stefan , Ackert Michael
Published: January 2022

The article examines the intensity and structure of religiosity and spirituality of German-speaking foot and bicycle pilgrims on the Way of St. James within the framework of a multidimensional model of religiosity. The following nine aspects are distinguished: religious questions, faith, religious and spiritual identity, worship, prayer, meditation, monistic and dualistic religious experiences. Data of N=425 German-speaking pilgrims of the Way of St. James from the years 2017 and 2018 are analyzed. The data of the Religion Monitor 2017 from Germany, Austria, and Switzerland (N=2837) serves as a population-representative comparison sample. Descriptive statistics, t-tests, and multiple regression analyses are used to analyze and to compare the two groups. The results show that German-speaking pilgrims in the analyzed sample have substantially higher values on all dimensions of religiosity than the general population in Germany, Austria, and Switzerland. This difference is most pronounced in the spiritual self-concept. However, for most pilgrims, the categories religious and spiritual are not mutually exclusive. Rather, spirituality forms a basis shared by almost all pilgrims in the sample, to which religiousness is added for many. Further, results are discussed in the light of the existing foot and bicycle pilgrimage research. Conclusively, it can be said that tourism and church actors should consider the religious character of pilgrims, which remains despite all changes in the religious landscape.
The Environmental Activism of a Filipino Catholic Faith Community: Re-Imagining Ecological Care for the Flourishing of All
Authors: Peracullo Jeane C. , Quindoza Rosa Bella M.
Published: January 2022

Extensive open-pit mining activities in the Philippines since the 1970s up to the present confront the meaning of the “Church of the Poor”, a description that the Catholic Church in the Philippines uses to visualize its prophetic mission. Alongside mining, many more environmentally destructive industries are present in the poorest areas in the country, even though the Philippines is disaster-prone and one of the world’s most vulnerable countries to the devastating effects of the climate crisis. The environmental degradation has prompted many Filipino Catholic organizations and communities to act together through various campaigns to address the problem. The article examines a case of a faith-based community that rose to the challenge to address various environmental issues their community has encountered and continues to experience. The community’s environmental activism presents a viable model for a re-imagined ecological care towards the “flourishing of all” as a response to Pamela McCarroll’s call to action to continue conversations on the many ways practical theology can move beyond anthropocentrism while focusing on social justice.
Translation or Divination? Sacred Languages and Bilingualism in Judaism and Lucumí Traditions
Authors: Nosonovsky Michael
Published: January 2022

I compare the status of a sacred language in two very different religious traditions. In Judaism, the Hebrew language is the language of liturgy, prayer, and the Written Law. The traditional way of reading Torah passages involved translating them into Aramaic, the everyday language of communication in the Middle East in the first half of the first millennium CE. Later, other Jewish languages, such as Yiddish, played a role similar to that of Aramaic in the Talmudic period, constituting a system referred to as the “Traditional Jewish Bilingualism”. Hebrew lexemes had denotations related to the realm of Biblical texts, while Aramaic/Yiddish lexemes had everyday references. Therefore, the act of translation connected the two realms or domains. The Lucumí (Santería) Afro-Cuban religion is a syncretic tradition combining Roman Catholicism with the Ifá tradition, which does not have a corpus of written sacred texts, however, it has its sacred language, the Lucumí (Anagó) language related to the Yoruba language of West Africa. While the Spanish-Lucumí bilingualism plays an important role in Santería rituals, the mechanisms of reference are very different from those of the Hebrew-Yiddish bilingualism in Judaism. In Santería, divinations about the meaning of Lucumí words play a role similar to the translations from Hebrew in Judaism. I further discuss the role of ritual dances in Santería for the transition from the sacred to the secular domain and a function of Hebrew epitaphs to connect the ideal world of Hebrew sacred texts to the everyday life of a Jewish community.
Navigating Extinction: Zen Buddhism and Eco-Anarchism
Authors: Holohan Kevin J.
Published: January 2022

What can esoteric knowledge and spiritual practices from the East teach us about the deep psychological roots of domination and hierarchy? In what ways have ancient Buddhist sages acted as anarchist exemplars and deep ecologists long before these traditions began in the West? How might these anarchistic spiritual traditions inform our approaches to work in education, expand our notions of community, help us navigate ecological collapse, and contribute to our efforts to sustain living systems and rekindle our connection to the myriad sentient inhabitants of the places we live beyond the reaches of capital and the State? This paper will examine the anti-doctrine doctrine of Zen Buddhism as a concrete and embodied system of thought and practice for seeing through the delusions of the ego and the psychological and cultural conditioning these delusions engender. What will also be acknowledged is the general lack of attention this spiritual tradition has given to the capitalistic, authoritarian, and anti-ecological systems that tap into and flow from these delusions. It will be argued that these experiential approaches to overcoming the tyranny of the ego have significant implications for loosening the grip of hierarchical thinking, capitalist hyper-consumption, centralized systems of obedience and command, and human destruction of the biosphere.

Bedforms are key components of Earth surfaces and yet their evaluation typically relies on manual measurements that are challenging to reproduce. Several methods exist to automate their identification and calculate their metrics, but they often exhibit limitations where applied at large scales. This paper presents an innovative workflow for identifying and measuring individual depositional bedforms. The workflow relies on the identification of local minima and maxima that are grouped by neighbourhood analysis and calibrated using curvature. The method was trialed using a synthetic digital elevation model and two bathymetry surveys from Australia’s northwest marine region, resulting in the identification of nearly 2000 bedforms. The comparison of the metrics calculated for each individual feature with manual measurements show differences of less than 10%, indicating the robustness of the workflow. The cross-comparison of the metrics resulted in the definition of several sub-types of bedforms, including sandwaves and palaeoshorelines, that were then correlated with oceanic conditions, further corroborating the validity of the workflow. Results from this study support the idea that the use of automated methods to characterise bedforms should be further developed and that the integration of automated measurements at large scales will support the development of new classification charts that currently rely solely on manual measurements.

In this paper, a fiber probe high-temperature sensor based on the Michelson Interferometer (MI) is proposed and experimentally verified. We used a fiber splicing machine to fabricate a taper of the single-mode fiber (SMF) end. The high order modes were excited at the taper, so that different modes were transmitted forward in the fiber and reflected by the end face of the fiber and then recoupled back to the fiber core to form MI. For comparison, we also coated a thin gold film on the fiber end to improve the reflectivity, and the reflection intensity was improved by 16 dB. The experimental results showed that the temperature sensitivity at 1506 nm was 80 pm/°C (100 °C~450 °C) and 109 pm/°C (450 °C~900 °C). The repeated heating and cooling processes showed that the MI structure had good stability at a temperature up to 900 °C. This fiber probe sensor has the advantages of a small size, simple structure, easy manufacturing, good stability, and broad application prospects in industrial and other environments.
The Persistence of Racial Constructs in Spain: Bringing Race and Colorblindness into the Debate on Interculturalism
Authors: Rodríguez-García Dan
Published: January 2022

In this article, I argue that persisting racial constructs in Spain affect conceptions of national belonging and continue to shape and permeate contemporary discriminations. I begin by describing several recent political events that demonstrate the urgent need for a discussion about “race” and racialization in the country. Second, some conceptual foundations are provided concerning constructs of race and the corollary processes of racism and racialization. Third, I present data from various public surveys and also from ethnographic research conducted in Spain on mixedness and multiraciality to demonstrate that social constructs of race remain a significant boundary driving stigmatization and discrimination in Spain, where skin color and other perceived physical traits continue to be important markers for social interaction, perceived social belonging, and differential social treatment. Finally, I bring race into the debate on managing diversity, arguing that a post-racial approach—that is, race-neutral discourse and the adoption of colorblind public policies, both of which are characteristic of the interculturalist perspectives currently preferred by Spain as well as elsewhere in Europe—fails to confront the enduring effects of colonialism and the ongoing realities of structural racism. I conclude by emphasizing the importance of bringing race into national and regional policy discussions on how best to approach issues of diversity, equality, anti-discrimination, and social cohesion.
Forest Soils—What’s Their Peculiarity?
Authors: Wilpert Klaus von
Published: January 2022

Mankind expects from forests and forest soils benefits like pure drinking water, space for recreation, habitats for nature-near biocenoses and the production of timber as unrivaled climate-friendly raw material. An overview over 208 recent articles revealed that ecosystem services are actually the main focus in the perception of forest soil functions. Studies on structures and processes that are the basis of forest soil functions and ecosystem services are widely lacking. Therefore, additional literature was included dealing with the distinct soil structure and high porosity and pore continuity of forest soils, as well as with their high biological activity and chemical soil reaction. Thus, the highly differentiated, hierarchical soil structure in combination with the ion exchange capacity and the acid buffering capacity could be described as the main characteristics of forest soils confounding the desired ecosystem services. However, some of these functions of forest soils are endangered under the influence of environmental change or even because of forest management, like mono-cultures or soil compaction through forest machines. In the face of the high vulnerability of forest soils and increased threads, e.g., through soil acidification, it is evident that active soil management strategies must be implemented with the aim to counteract the loss of soil functions or to recover them.
Risk-Cost Optimized Maintenance Strategy for Steel Bridge Subjected to Deterioration

Published: January 2022

This paper aims to develop a deteriorated bridge maintenance strategy that ensures the safe operation of steel structures and minimizes the total risk. Five common failure modes are considered for the deteriorated bridge: flexure, shear, deflection, fatigue failure for girder, and chloride attack for the concrete deck. Time-dependent and system reliability analyses are carried out to find the probability of failure under these failure modes. Risk-cost optimization is then used to determine the maintenance strategy. This method was applied to a working example. It was found that the developed maintenance strategy can predict when, where, and what to maintain for a bridge to ensure its safe and serviceable operation during its lifespan. The proposed methodology can help structural engineers and asset managers repair and maintain bridges under deterioration.
Influence of the Built Environment on Physical Activity Choices among Emirati Male and Female Adolescents: An Examination of Parents’ and Students’ Perceptions

The UN Human Development Report 2020 ranked the United Arab Emirates (UAE) as having achieved ‘very high human development’ and as being at the 31st position among all countries. Despite this, the ever increasing obesity rates among Emirati youth, higher than international standards, is alarming. This research aims at identifying how different perceptions of the built environment by parents and adolescents are likely to affect physical activity (PA) choices among male and female Emirati youth. This can help inform better health and education policies to achieve three of the interconnected UN Sustainable Development Goals (SDGs), namely good quality health and well-being, quality education, and gender equality, that the UAE strives to achieve. Responses from 335 students (aged 14–20) from six schools and 250 parent responses in the Al Ain region of Abu Dhabi Emirate were used to understand the mean variation in perception of five built environment constructs. Further, multinomial logit regression was used to assess the health condition using the perception, behavior, and built environment measures. Results indicate that Emirati males perceive the built environment factors as barriers more than female adolescents. Parents perceive street crossing (p < 0.016) and sidewalk characteristics (p < 0.020) to be more of a hindrance. Traffic exposure, self-reported physical activity, and walkability near homes and schools significantly affect Emirati adolescents’ health conditions. Recommendations are made for various stakeholders including parents, school authorities, Abu Dhabi Municipality and Transportation, and the Urban Planning department on ways to enhance the built environment and encourage PA and well-being of Emirati adolescents.
Analysis of Traffic Operation Characteristics and Calculation Model of the Length of the Connecting Section between Ramp and Intersection
Authors: Wang Fu , Gu Dengjun , Chen Anqi
Published: January 2022

Many cities have built expressways to alleviate traffic congestion, among which elevated expressways are the most common form. However, traffic congestion still occurs frequently in the connecting section between the ramp of expressway and the ground intersection. Based on the field traffic survey data, the traffic operation characteristics of vehicles in the connecting section and the main factors affecting the length of the connecting section are analyzed. A combined model for calculating the length of the connecting section between ramp of urban expressway and intersection is proposed. VISSIM is used to simulate the traffic flow under the current and calculated length of the connecting section. The comparison results show that under the calculation length, the travel time, average delay, parking time and queue length are reduced to varying degrees, which verifies the rationality of the calculation model.

Published: January 2022

It is well-known that on-site measurements are suitable for verifying the actual thermal performance of buildings. Performance assessed in situ, under actual thermal conditions, can substantially vary from the theoretical values. Therefore, experimental measurements are essential for better comprehending the thermal behavior of building components, by applying measurement systems and methods suitable to acquire data related to temperatures, heat flows and air speeds both related to the internal and external environments. These data can then be processed to compute performance indicators, such as the well-known thermal transmittance (U-value). This review aims at focusing on two experimental techniques: the widely used and standardized heat flow meter (HFM) method and the quite new thermometric (THM) method. Several scientific papers were analyzed to provide an overview on the latest advances related to these techniques, thus providing a focused critical review. This paper aims to be a valuable resource for academics and practitioners as it covers basic theory, in situ measurement equipment and criteria for sensor installation, errors, and new data post-processing methods.
