FORMATION OF A SYMBIOTIC APPARATUS OF ALFALFA DEPENDING ON THE NITROGEN NUTRITION TYPE
Authors: Kozyreva Marina , Basieva Larisa
Published: May 2020

The experiments were carried out in 2017–2019 in the foothill zone of North Ossetia-Alania (540 m above sea level) on leached chernozem. The effect of the mineral and symbiotrophic types of nitrogen nutrition on the formation of the alfalfa symbiotic apparatus was compared to optimize the cultivation agricultural technique. The experimental design included the following options: control - natural soil fertility; In-1800 - seed treatment with the inoculum of nitrogen-fixing bacteria strains selected in high mountain conditions (1800 m above sea level); Strain 425a - seed inoculation with an industrial strain of rhizotorphin (strain 425a); N30 - starting dose of nitrogen; N30+In - combined use of high-mountain strains of bacteria and starting doses of nitrogen. Seeds were treated with the studied strains before sowing. The formation of nodules on the roots of alfalfa during inoculation of seeds with rhizobia strains occurred 1 ... 2 days earlier than in the control, which indicates their greater activity compared to the local microflora. The duration of the general symbiosis in the second year of life in the variants with inoculation with industrial and alpine strains reached 215 ... 216 days, which is 4 ... 7 days more than in the control and variant N30. The greatest number of nodules in all years was noted during seed treatment with the inoculum of alpine rhizobia strains, both in pure form (96 ... 248 units/plant.), and against the background of the use of starting doses of nitrogen (80 ... 243 units/plant.). The smallest mass of nodules in the experiment (40 ... 255 kg/ha) was recorded in the control and variant N30. The highest mass of nodules was formed by the second crop of the second year of sowing life and exceeded 300 kg/ha in all variants with pre-sowing seed inoculation with active rhizobia strains. The superiority of the In-1800 variant over control was 28.3%, and the differences with N30+In turned out to be insignificant.

A Theory of Multilevel Information Privacy Management for the Digital Era
Authors: Bélanger France , James Tabitha L.
Published: May 2020

In the digital era, it is increasingly important to understand how privacy decisions are made because information is frequently perceived as a commodity that is mismanaged. The preponderance of privacy literature focuses on individual-level information privacy concern and personal self-disclosure decisions. We propose that a more versatile multilevel description is required to enable exploration of complex privacy decisions that involve co-owned (i.e., group) information in increasingly sophisticated digital environments. We define the concepts of group and individual information privacy, “we-privacy” and “I-privacy” respectively, as the ability of an individual or group to construct, regulate, and apply the rules for managing their information and interaction with others. We develop the theory of multilevel information privacy (TMIP), which uses the theory of communication privacy management and the developmental theory of privacy as foundations for a social rule-based (i.e., normative) process of making privacy decisions that evolve over time with experience. The TMIP contributes to the privacy literature by drawing from prominent social psychology theories of group behavior (i.e., social identity and self-categorization theories) to explain how privacy decisions can be made by individuals or groups (i.e., social units) or social units acting as members of a particular group. We contend that technology complicates the privacy decision-making process by adding unique environmental characteristics that can influence the social identity assumed for a particular privacy decision, the estimation of the cost-benefit components of the privacy calculus, and the application and evolution of the norms that define the rules for information and interaction management. We discuss the implications of the TMIP for information systems research and provide a research agenda.

Personal protective equipment and testing during the COVID-19 pandemic
Authors: Higginson Ray , Jones Bridie , Kerr Tamara , Ridley Anne-Marie
Published: May 2020

COVID-19 is caused by the severe acute respiratory syndrom coronavirus 2 (SARS-CoV-2) virus. The virus poses specific problems for cardiac nurses, with nurses being at the frontline of healthcare delivery. These issues not only involve treating and caring for cardiac patients with the virus, but also include the need to continue routine cardiac interventions during the pandemic. Many cardiac interventions are invasive, requiring close patient contact. As such, these interventions pose significant infection risks. To mitigate against these risks, cardiac nurses should follow established infection control guidelines and wear personal protective equipment where appropriate. Ongoing research is also demonstrating the usefulness of COVID-19 testing, the results of which will aid in the detection of the virus and enable any self-isolating nurses to return to work, where appropriate.

Digital holographic interferometry investigation of liquid hydrocarbon vapor cloud above a circular well
Authors: Shukla Digvijay , Panigarhi Pradipta K.
Published: May 2020

The current study investigates evaporation of liquid hydrocarbons from a circular well cavity of small depth. Gravimetric analysis is performed to measure the evaporation rate and digital holographic interferometry is used for the measurement of normalized mole fraction profile inside the vapor cloud above the well. Phase unwrapping has been implemented to obtain continuous phase distribution in the image plane. The Fourier–Hankel tomographic inversion algorithm is implemented to obtain the refractive index change distribution inside the object plane, i.e., vapor cloud. Four liquid hydrocarbons, i.e., pentane, hexane, cyclohexane, and heptane, are studied. The radius of circular well cavities is varied in the range of 1.5 to 12.5 mm. Results using a quasi-steady, diffusion-controlled model are compared with the experimental evaporation rate. Measured evaporation rates are higher than the diffusion-limited model calculation for all working fluids and well sizes. This difference is attributed to natural convection occurring inside the vapor cloud due to the density difference between the gas–vapor mixture and the surrounding air. Holographic analysis confirms the presence of natural convection by revealing the formation of a flat disk-shaped vapor cloud above the well surface. Experimentally obtained vapor cloud shape is different from the hemispherical vapor cloud obtained using the pure diffusion-limited evaporation model. The gradient of vapor mole fraction at the liquid–vapor interface is higher compared to that of the diffusion-limited model because of the additional transport mechanism due to natural convection. Transient analysis of the vapor cloud reveals time invariant overall shape of the vapor cloud with a reduction in average magnitude of vapor concentration inside the vapor cloud during evaporation. The existing correlation for sessile droplet cannot successfully predict the evaporation rate from a liquid well. A new correlation is proposed for evaporation rate prediction, which can predict the evaporation rate within a root mean square error of 5.6% for a broad size range of well cavity.
Near-infrared saturable and reverse saturable absorption of ion beam synthesized VO2 nanocrystals
Authors: Mundry Jan , Krenner Hubert J. , Karl Helmut , Betz Markus
Published: May 2020

We investigate the nonlinear optical response of a thin film of ion-implanted VO2 nanocrystals with open aperture z-scans involving femtosecond near-infrared pulses. Beyond the established nonlinearity related to the insulator-metal phase transition of VO2, the metallic state features a pronounced saturable absorption for 100 fs pulses from a modelocked Yb:fiber source at λ = 1036 nm. In contrast, we find a pronounced reverse saturable absorption for 90 fs pulses in the telecom window at λ = 1550 nm. We attribute these nonlinearities to a transient red-shift of the plasmonic resonance of the nanocrystals, in line with the temperature dependence of the linear absorption and the theoretical expectation for electronic heating. Details of the transmissivity characteristics can be tailored by the lattice temperature and/or the size of the nanocrystals. The results hold promise for the use of VO2 nanocrystals as a saturable absorber, e.g., to mode-locked near-infrared lasers.
Stitching a sensibility for sustainable clothing: Quiet activism, affect and community agency
Authors: Hackney Fiona , Saunders Clare , Willett Joanie , Hill Katie , Griffin Irene
Published: May 2020

Fast fashion has become notorious for its environmental, social and psychological implications. This article reports on some of the work undertaken as part of the Arts and Humanities Research Council (AHRC)-funded ‘S4S: Designing a sensibility for sustainable clothing’ project, which sought to combine social science and participatory arts-based research methods to explore how processes of ‘making together’ in community textiles groups might generate a new ethic, or sensibility, among consumers to equip them to make more sustainable clothing choices. The study develops a novel methodology that responds to the complex demands of participatory working. It required careful management of the combinations of methods, which included various different making workshops; wardrobe audits; interviews; films and journal keeping. The project also raises the question of using multi-modal formats, which generate rich data, but also add to the complexity, highlighting a need for multi-disciplinary teams. The article focuses on participant responses from two series of five-day workshops that explored: (1) hand-making fabrics by spinning, dyeing and weaving thread; and (2) deconstructing and reconstructing knitted garments. The embodied encounters offered in the workshops encouraged participants to reflect on the fluidity of garments, by which we mean coming to view clothing not as fixed objects but rather as open and full of potentiality for change. For example, a jumper might be unravelled and the wool used for a different piece of clothing, or a dress unpicked and the fabric used for some entirely different garment. The resultant affective responses ranged from a deeper engagement with the materialities of the clothing industry to an awareness of the amount of time incorporated in the process of making clothes as participants started to re-imagine clothing through the embodied act of re-making.
From scene films to scene videos: Communities documenting communities
Authors: Tenreiro Uzal Cibrán
Published: May 2020

The activity of local music scenes has at times been documented by members of those communities in films that differ from commercial audio-visual products in their mode of production, their aesthetics and the way they represent the reality of musical activities. The collaborative character of local scenes and the DIY ethos of many of them help shape these works, where artistic intentions and experimentation coexist with their use for self-learning or the construction of personal memories. This article identifies the features of these scene films, both in documentary and fiction, and explores how technological changes and the digital age have influenced them.
‘Coming into focus’: Realizing the potential of strange girl cinema in Todd Haynes’s Carol
Authors: Pelucacci Lindsey
Published: May 2020

This article explores the 2015 film Carol, reading the two protagonists’ mutual coming-into-focus as emblematic of the film’s calling-into-focus cinematic representations of love, motherhood and artistry in relation to the intersections of queer and gendered challenges. In observing these challenges, the cinematic camera adopts the disposition of Therese, a ‘strange girl’, as Carol calls her, who develops a loving inquisitiveness that drives her towards romantic and artistic discovery. The film depicts and itself utilizes what I call a ‘strange girl gaze’, which, marked by a gentle curiosity and a willingness to listen to alternate perspectives, counters the domineering gaze of heteropatriarchal surveillance. Using a queer understanding of hope, my article considers the cinematic potential of this new way of looking, which attends to socially peripheral individuals, including their painful pasts, with innocence, open-mindedness and compassion.
Revisitar Vieira no séc. XXI - Cultura Política e Atualidade Vol. I
Authors: Franco José Eduardo , Pereira Paulo Silva
Published: May 2020

“Se revisitamos o Padre António Vieira no século XXI, inevitavelmente reconhecemos nele a pluralidade de abordagens [...]: antes de mais, ele foi (e é) um pensador da nossa cultura e da política do seu tempo, desenvolvendo temas que demarcam aquilo a que chamamos a sua atualidade; e não é seguramente banal rastrear um sentido de atualidade evidente em quem viveu, pensou, pregou e escreveu há mais de três séculos. Assim é, mas não se trata só disso. O legado do Padre António Vieira projeta-se também, até hoje, na nossa língua, no imaginário dos seus grandes cultores, nas artes e na sua presença no sistema de ensino. Os textos que aqui podemos ler atestam bem o que fica dito: a imagem de Vieira na nossa historiografia, a epistolografia e o seu culto, a obra profética e as indagações a que convida, a ousadia do pensamento teológico, o trajeto de vida (um trajeto que fez desta grande figura quase uma personagem de ficção, conforme o cinema confirmou), a intervenção política a que não se esquivou, o contributo inigualável que deu à oratória sagrada.”

UM BALANÇO DOS 30 ANOS DA CONSTITUIÇÃO FEDERAL DE 1998: OS DIREITOS HUMANOS NA JURISPRUDÊNCIA E NOS JUÍZES
Authors: Santano Ana Claudia
Published: May 2020

Os 30 anos da Constituição de 1988 testemunharam um momento de plena ascensão no reconhecimento dos direitos humanos na ordem constitucional brasileira, a partir do maior rol de direitos fundamentais em seu conteúdo. Contudo, é inegável que há uma crise, que não vem só dessa recognição, mas da própria noção de direitos humanos, comprometendo a frágil consolidação desses valores. Diante disso, por meio de uma breve revisão doutrinária e de análise de alguns dados da jurisprudência do STF e do Tribunal de Justiça do estado do Paraná, este ensaio irá abordar como caminha a abertura constitucional para os direitos humanos internacionais. Verificou-se que ainda há gargalos nesse processo que prejudicam a consolidação desses valores internamente e que, de certa forma, colaboram para a crise apontada. Ao final, traça-se um panorama do que se espera para os próximos 30 anos, principalmente no que se refere à adesão do Brasil a um Ius Constitutionale Commune, já presente no âmbito latino-americano.

Women are a very productive source of labor in all fields. In this case village women tend to be housewives and their space to develop skills is very limited. Researchers aimed to determine the empowerment of cadres in the family welfare in the District of Pakis, Magelang Regency. This research is a qualitative research with a descriptive approach. The subjects of this study were the Head of the Banyusidi Village, the Driving Cadre of the Banyusidi Village. In collecting data researchers used the method of observation, interviews and documentation. While in the data analysis techniques researchers used data collection, data reduction, data presentation and drawing conclusions. The results showed that PKK Cadre Empowerment based on the theory of the empowerment process was divided into 5 stages namely Enabling, Empowering, Protecting, Supporting, and Fostering. Of the 5 stages the process has not been able to run optimally, especially in Enabling and Fostering. While the factors which become obstacles in empowering women through PKK come from members and also from the environment. While the supporters are strong encouragement from the board and the existence of support from outside the group.Keywords: Empowerment of women, PKK, Family Welfare

Every family would want a clean and healthy environment. The level of achieving social welfare can also be passed through behaviors that reflect cleanliness of the environment. This also applies to scavenger families in Babarsari's shanties. In this context, the research was conducted in Babarsari's shanties in the type of field research and was descriptive qualitative in nature. Those who work as scavengers do not recognize clean and healthy living behaviors or PHBS. They are used to environmental life which can be said to not support the survival of their children. An environment full of garbage has become their usual sight. To analyze PHBS, Abraham Maslow's theory of Hirearki's theory of Human Needs is used. The results of this study are that those scavenger families do not have the awareness of the importance of basic needs, such as clean and healthy life behavior or PHBS.Keywords: Social Welfare, Family, Scavenger, Healthy Living Behaviors

O potrzebie kształtowania autonomii poznawczej i egzystencjalnej na lekcjach nie tylko języka polskiego
Authors: Myrdzik Barbara
Published: May 2020

Tekst zatytułowany O potrzebie kształtowania autonomii poznawczej i egzystencjalnej na lekcjach nie tylko języka polskiego podejmuje zagadnienie roli autonomii w edukacji. Prezentuje znaczenie pojęcia autonomia w edukacji europejskiej i w edukacji polskiej. Przedstawia warunki, jakie powinno spełnić państwo demokratyczne, by można realizować w szkole autonomię poznawczą, która wiąże się z poczuciem niezależnego działania podmiotu oraz pozostawienia miejsca dla wolnej decyzji, zapewnienia możliwości ciągłego, harmonijnego i wszechstronnego rozwoju. Rozwój ten odbywa się w warunkach normowania życia przez różne wspólnoty, jak rodzina, szkoła, Kościół, stowarzyszenia itd. Ma zatem dwie sfery: instytucjonalną i indywidualną. Instytucjonalny sens autonomii dostrzegamy w działaniu szkoły jako instytucji i w relacjach interpersonalnych, dotyczy też zakresu niezależności i swobody działania jednostki i wspólnoty, przyznanego im przez rządzących. Ważną częścią tekstu jest prezentacja możliwości działań nauczyciela i ucznia w systemie demokratycznym, pozwalającym na swobodę w wyborze programu wychowawczego i poznawczego na „miarę ucznia”. Tekst omawia również przeszkody, jakie pojawiają się w drodze do uzyskania autonomii, zarówno uwarunkowane administracyjnie, jak i indywidualnymi zachowaniami uczniów i nauczycieli.
Ewolucja dyskursu o partycypacji społecznej dzieci
Authors: JAROSZ EWA
Published: May 2020

Koncepcja partycypacji społecznej dzieci jest w dzisiejszym świecie rozumiana jako wielowymiarowa, wielopostaciowa, a także konieczna do wdrażania na różnych poziomach społecznych. Od chwili jej wyrazistego sformułowania w Konwencji o prawach dziecka z 1989 roku, rozwój naukowego i praktycznego dyskursu na temat partycypacji dzieci charakteryzuje swoista ewolucja, której cechą jest zmiana istoty rozumienia znaczenia partycypacji dzieci z narzędzia rozwoju podmiotowości dziecka oraz rozwoju demokracji w społeczeństwie – jak było to we wcześniejszych dekadach – na postrzeganie jej jako wartości samej w sobie oraz pożądanej cechy charakteryzującej życie społeczne. Obecnie oznacza ona również akcentowanie zbiorowego wymiaru partycypacji dzieci oraz przesunięcie teoretycznego kontekstu idei w obszar teorii społeczno-politycznych. Artykuł przedstawia szkic charakterystyki owej ewolucji.
The Politics of Education in Developing Countries: From Schooling to Learning

The issue of quality in education is still one of the key current debates within international education policy. There are comments that development education has a significant contribution to make to these debates. Skinner, Blum and Bourn (2013) suggested that greater collaboration between the field of development education and international education policy could facilitate the creation of an agenda that focuses on education quality and learning processes, as opposed to the current preoccupation with education access and outcomes.
Weak and stationary solutions to a Cahn–Hilliard–Brinkman model with singular potentials and source terms
Authors: Ebenbeck Matthias , Lam Kei Fong
Published: May 2020

We study a phase field model proposed recently in the context of tumour growth. The model couples a Cahn–Hilliard–Brinkman (CHB) system with an elliptic reaction-diffusion equation for a nutrient. The fluid velocity, governed by the Brinkman law, is not solenoidal, as its divergence is a function of the nutrient and the phase field variable, i.e., solution-dependent, and frictionless boundary conditions are prescribed for the velocity to avoid imposing unrealistic constraints on the divergence relation. In this paper we give a first result on the existence of weak and stationary solutions to the CHB model for tumour growth with singular potentials, specifically the double obstacle potential and the logarithmic potential, which ensures that the phase field variable stays in the physically relevant interval. New difficulties arise from the interplay between the singular potentials and the solution-dependent source terms, but can be overcome with several key estimates for the approximations of the singular potentials, which maybe of independent interest. As a consequence, included in our analysis is an existence result for a Darcy variant, and our work serves to generalise recent results on weak and stationary solutions to the Cahn–Hilliard inpainting model with singular potentials.

Published: May 2020

We consider an elliptic variational-hemivariational inequality 𝓟 in a reflexive Banach space, governed by a set of constraintsK, a nonlinear operatorA, and an elementf. We associate to this inequality a sequence {𝓟n} of variational-hemivariational inequalities such that, for eachn∈ ℕ, inequality 𝓟nis obtained by perturbing the dataKandAand, moreover, it contains an additional term governed by a small parameterεn. The unique solvability of 𝓟 and, for eachn∈ ℕ, the solvability of its perturbed version 𝓟n, are guaranteed by an existence and uniqueness result obtained in literature. Denote byuthe solution of Problem 𝓟 and, for eachn∈ ℕ, letunbe a solution of Problem 𝓟n. The main result of this paper states the strong convergence ofun→uinX, asn→ ∞. We show that the main result extends a number of results previously obtained in the study of Problem 𝓟. Finally, we illustrate the use of our abstract results in the study of a mathematical model which describes the contact of an elastic body with a rigid-deformable foundation and provide the corresponding mechanical interpretations.

The study aims to examine the risk factors for increased colorectal cancer (CRC) markers in patients with type 2 diabetes mellitus (T2DM). The 229 patients retrospectively reviewed were categorized into two groups: CRC tumor marker-positive and -negative groups. Patients who tested positive for all three of the following CRC markers were included in the CRC tumor marker-positive group: serum carcinoembryonic antigen, carbohydrate antigen 19-9 and septin9 methylation. Univariate analysis revealed that most CRC marker-positive patients had higher age, a family history of CRC, history of smoking and alcohol intake, high body mass index (BMI; overweight), longer history of T2DM, worse diabetes control (with high glycated hemoglobin A1c [HbA1c]), lower level of serum vitamin D (VD), high-density lipoprotein cholesterol and higher level of total cholesterol and triglyceride (TG). Logistic regression analysis showed that BMI, VD, HbA1c and TG were independent predictors of CRC marker-positive status (OR, 95% confidence intervals and P values were 1.912 [1.346–2.716], <0.001; 0.773 [0.633–0.943], 0.011; 9.082 [3.52–23.433], <0.001; and 11.597 [3.267–41.164], <0.001, respectively). In this retrospective study, high BMI, HbA1c and TG as well as low level of VD were correlated with CRC tumor marker-positive status in T2DM patients. Patients with these risk factors may benefit from more frequent screening for CRC tumor markers.

A transfemoral prosthesis is required to assist amputees to perform the activity of daily living (ADL). The passive prosthesis has some drawbacks such as utilization of high metabolic energy. In contrast, the active prosthesis consumes less metabolic energy and offers better performance. However, the recent active prosthesis uses surface electromyography as its sensory system which has weak signals with microvolt-level intensity and requires a lot of computation to extract features. This paper focuses on recognizing different phases of sitting and standing of a transfemoral amputee using in-socket piezoelectric-based sensors. 15 piezoelectric film sensors were embedded in the inner socket wall adjacent to the most active regions of the agonist and antagonist knee extensor and flexor muscles, i. e. region with the highest level of muscle contractions of the quadriceps and hamstring. A male transfemoral amputee wore the instrumented socket and was instructed to perform several sitting and standing phases using an armless chair. Data was collected from the 15 embedded sensors and went through signal conditioning circuits. The overlapping analysis window technique was used to segment the data using different window lengths. Fifteen time-domain and frequency-domain features were extracted and new feature sets were obtained based on the feature performance. Eight of the common pattern recognition multiclass classifiers were evaluated and compared. Regression analysis was used to investigate the impact of the number of features and the window lengths on the classifiers’ accuracies, and Analysis of Variance (ANOVA) was used to test significant differences in the classifiers’ performances. The classification accuracy was calculated using k-fold cross-validation method, and 20% of the data set was held out for testing the optimal classifier. The results showed that the feature set (FS-5) consisting of the root mean square (RMS) and the number of peaks (NP) achieved the highest classification accuracy in five classifiers. Support vector machine (SVM) with cubic kernel proved to be the optimal classifier, and it achieved a classification accuracy of 98.33 % using the test data set. Obtaining high classification accuracy using only two time-domain features would significantly reduce the processing time of controlling a prosthesis and eliminate substantial delay. The proposed in-socket sensors used to detect sit-to-stand and stand-to-sit movements could be further integrated with an active knee joint actuation system to produce powered assistance during energy-demanding activities such as sit-to-stand and stair climbing. In future, the system could also be used to accurately predict the intended movement based on their residual limb’s muscle and mechanical behaviour as detected by the in-socket sensory system.

Objectives

In this study, the performance of OpenBCI, a low-cost bio-amplifier, is assessed when used for 3D motion reconstruction.

Methods

Eleven scalp electrode locations from three subjects were used, with sampling rate of 125 Hz, subsequently band-pass filtered from 0.5 to 40 Hz. After segmentation into epochs, information-rich frequency ranges were determined using filter bank common spatial filter. Simultaneously, the actual hand motions of subjects were captured using a Microsoft Kinect sensor. Multimodal data streams were synchronized using the lab streaming layer (LSL) application. A modified version of an existing multiple linear regression models was employed to learn the relationship between the electroencephalography (EEG) feature input and the recorded kinematic data. To assess system performance with limited data, 10-fold cross validation was used.

Results

The most information-rich frequency bands for subjects were found to be in the ranges of 5 – 9 Hz and 33 – 37 Hz. Hand lateralization accuracy for the three subjects were 97.4, 78.7 and 96.9% respectively. 3D position reconstructed with an average correlation coefficient of 0.21, 0.47 and 0.38 respectively along three pre-defined axes, with the corresponding average correlation coefficients for velocity being 0.21, 0.36 and 0.25 respectively. The results compare favourably with a cross-section of existing results, while cost-per-electrode costs were 76% lower than the average per-electrode cost for similar systems and 44% lower than the cheapest previously-reported system.

Conclusions

This study has shown that low-cost bio-amplifiers such as the OpenBCI can be used for 3D motion reconstruction tasks.
Assessing the Dating Potential of Violet Stimulated Luminescence Protocols
Authors: Sontag-González Mariana , Frouin Marine , Li Bo , Schwenninger Jean-Luc
Published: May 2020

Violet stimulation is a new development in optical dating which has been suggested to extend the upper age limit of optically simulated luminescence (OSL) dating of quartz. Despite the reported advantage, few validation tests and applications have been published so far. The present study investigated the violet stimulated luminescence (VSL) using a single aliquot regenerative dose (SAR) protocol and a multiple aliquot additive dose (MAAD) protocol. Sedimentary quartz samples from four archaeological sites in Europe with independent age controls spanning 40–900 ka were used, including Grotte Mandrin (France), Brooksby Quarry (UK), Cueva Negra del Estrecho del Río Quípar (Spain) and Sima de las Palomas del Cabezo Gordo (Spain). The equivalent dose of a relatively young sample (∼40 ka) was successfully determined. However, significant underestimations were observed for older samples with higher doses. These findings indicate the need for further development of the measurement protocol to date high-dose natural samples.
Non-noble metal based broadband photothermal absorbers for cost effective interfacial solar thermal conversion

Published: May 2020

In recent years, noble metal-based solar absorbers have been extensively studied as their pronounced plasmonic resonances and high solar-to-thermal conversion efficiency. However, the high cost of noble metals is the unavoidable roadblock restricting the way towards scalability. In this work, we report a nickel-based photothermal absorbers, which is capable of realizing an average solar absorption of ∼97% in the range of 400–2500 nm originating from relatively weaker collective plasmonic resonances but more pronounced single electron excitation. Importantly, it is easily fabricated via the straightforward physical deposition and cost-effective with a raw material price of ∼0.3% gold and ∼20% of silver. We used it for interfacial solar vapor generation and realized an evaporation rate of ∼0.9 kg m−2 h−1 under one sun, almost comparable to the counterparts made from noble metals. The excellent performance combined with the cost effective and scalable fabrication process makes it be a promising candidate for mass off-grid solar desalination.
Virtuality and the Problem of Agency in Object-Oriented Ontology
Authors: Baranovas Ruslanas
Published: May 2020

In hisPrince of Networks, Graham Harman reconstructs Latourian critique of concepts of potentiality and virtuality with which he claims to agree. This seems striking because Latour’s arguments seem to be exactly those Harman rejects in his other writings as overmining. Furthermore, this critique of potentiality and virtuality creates a dividing line between Harman and Bryant’sDemocracy of Objects, where the concept of virtual plays a central role. In this article, I will explore this debate, focusing on how the concept of virtuality works in the context of the ontological realism that Object-Oriented Ontology is. To do this, I will first present Bryant’s notion of virtuality focusing on the problem of the individuality of the object. Then I will explore Latourian–Harmanian arguments against virtuality and show that the main issue Harman has with virtuality has to do with the agency of objects. Therefore, I claim that the main dividing line between Bryant’s and Harman’s versions of Object-Oriented Ontology is the difference between the two notions of agency.
Synthetic cell-permeable caveolin-1 scaffolding domain peptide activates phagocytosis of Escherichia coli by regulating Rab5 activity
Authors: Hagiwara Makoto , Matsushita Kenji
Published: May 2020

Caveolae are defined as 50–100 nm wide pits in the plasma membrane containing oligomeric caveolin proteins. They have been implicated in endocytosis (including phagocytosis), transcytosis, calcium signalling, and numerous other signal transduction events. Caveolin-1, a major structural component of caveolae, enhances Rab5 activity. In this study, we examined the effect of a synthetic cell-permeable peptide of the caveolin-1 scaffolding domain (CSD) on phagocytosis. Treatment with the CSD peptide increased Rab5 activity, Rab5-early endosome antigen 1 (EEA1) interaction, and phagocytosis of Escherichia coli. The results suggest that the synthetic cell-permeable CSD peptide is an activator of phagocytosis.
Through Madness and Back Again
Authors: Johnston Matthew S.
Published: May 2020

This article traces my struggles with psychosis, arrest, psychiatric institutionalization, and recovery. Mobilizing a cathartic approach to autoethnography, I reveal my resistances, resiliencies, oppressions, nightmares, and recovery processes in the mental health system as I became entangled in another, darker reality and tried desperately to escape it. This work is a contribution to the emerging field of Mad Studies that seeks to privilege lived experiences with madness and the mental health system as a way of knowing. I found that doing an autoethnography of the mind helps recover the pieces of a fragmented identity and heals some of the visceral horrors that haunts us through and beyond experiences with mental illness.
