The meaningful art of one of the ‘worst movies of all time’: Phil Tucker’s Robot Monster (1953) as an existentialist critique of American modernity
Authors: Tilsley Daniel
Published: April 2022

This article analyses one of the ‘worst movies ever made’, Robot Monster (), demonstrating how the text, through weirdness, pulpy absurdity and cinematic ineptitude, examines and mediates on the existential anxieties of modern America during the Cold War. Through the strange language of gorilla-robots and alien invasion, the text articulates those existential anxieties that arise from our awareness of freedom vs. the need to be contingent under increasingly interconnected societal conditions. As such, Robot Monster is also posited as a contribution to contemporary intellectual currents of the 1950s. This article will investigate the sense in which the key aspects of the film: Ro-Man society as mass society; Ro-Man as conflicted between ‘must’ and ‘cannot’; Ro-Man as a gorilla-robot; the perspective of Johnny’s dream, articulate and mediate on those anxieties. An examination of Robot Monster allows us to appreciate the ways in which ‘bad’ cinema creates alternative ways of seeing the problems and existential anxieties of contemporary American modernity.
Real scary/scary real: Consuming simulated and authentic horrors in the digital era
Authors: Lonergan Meg D.
Published: April 2022

Snuff, like porn, has been challenged by feminist and other political debates around representations focused on the body, exaggerated performance, claims of ‘realness’ and concerns about representing and/or encouraging violence against women. Thus, it is not surprising that simulated snuff horror, as a subgenre, is heavily influenced by the same technological changes that have also affected the porn industry: the content of the videos, how the videos are produced and how they are consumed. I argue that the decontextualized digital context of media production and consumption has especially lent itself to the subgenre of horror I refer to as ‘simulated snuff films’ and aids in the longevity of snuff mythology. I use the terminology simulated snuff films to differentiate these fictional, from authentic snuff. Building on Steve Jones’ work, I explore the consumption of simulated snuff films that are scary real – fictional content that purposefully attempts to approximate the imagined look of a real snuff film – and films that are real scary – authentic depictions of extreme sexual violence and death – which may not give the appearance of being real or may be read by audiences as being faked. Further, using Jean Baudrillard’s theories of Simulation and Simulacra (1981), I argue that the case of Luka Magnotta, and his now infamous internet videos, exemplifies the hyperreality of snuff films in the post-9/11 context. To put it another way, simulated snuff films now appear more real than authentic recordings of murder in the digital sphere.
‘Awed listening’: H. P. Lovecraft in classic and contemporary audio horror
Authors: Hand Richard J.
Published: April 2022

From the beginnings of radio drama to digital podcasting, horror has been a significant genre. Radio located an immediate and effective affinity with horror, exploiting the form’s qualities of invisibility, immersivity and suggestion in realizing the genre in on-air performance. As a part of this, adaptation – from Gothic classics to populist fiction – has been central. One conspicuous absence in early radio is H. P. Lovecraft with only one notable adaptation in the 1930–1950s ‘golden age’. Nevertheless, in the radio work of Lovecraft acolyte Robert Bloch as well as shows such as Quiet, Please (1947–49) the ‘Lovecraftesque’ is strongly evident. Indeed, various dimensions to Lovecraft’s fiction make his oeuvre ideally suited to audio adaptation. In recent times, the transmedia pre-eminence of Lovecraft is evident in audio culture as much as anywhere else. This article scopes the presence of Lovecraft in both classic and contemporary contexts of horror audio.

Published: April 2022

Introducción y objetivo: Las fístulas de líquido cefalorraquídeo (LCR) pueden producirse tras un traumatismo, esto conlleva una disrupción entre la aracnoides y la duramadre, frecuentemente asociado a un defecto óseo. La epidemia mundial producida por la COVID-19 ha generado la necesidad de disponer de test rápidos para la detección del virus en mucosa nasal y orofaríngea. Los hisopos nasales (HN) han demostrado ser útiles a la hora de recoger muestras nasofaríngeas y por lo tanto se ha generalizado su uso. El objetivo de este artículo recae en describir una potencial complicación del test PCR mediante HN, como es la fístula de LCR, mediante el reporte de un caso clínico. Método: Se expone el caso de una paciente que sufre una fístula de LCR tras realización de test PCR mediante HN, se explica el diagnostico y manejo detallando las pruebas complementarias y el tratamiento final. Discusión: La fístula de LCR es una complicación poco frecuente de los test con HN. A pesar de esto, existen y hay que pensar en ella ante una rinorrea unilateral persistente tras realizar este test. En la actualidad tan sólo hay escasos casos en la publicados literatura que describan esta complicación. Conclusiones: Aunque la prueba de HN para diagnostico de la COVID-19 se considera segura, en ocasiones puede conllevar complicaciones. La aparición de rinorrea clara unilateral o goteo post nasal de sabor salado o metálico tras la realización de un HN nos debe poner en alerta a la hora de diagnosticar una posible fístula de LCR. Es de suma importancia instruir adecuadamente al personal sanitario que realiza el test, indicando la dirección y orientación correcta del hisopo. Además, se debe informar al paciente sobre los síntomas y signos de alarma. En pacientes con alteraciones previas de la base del cráneo, distorsión de la anatomía nasal o cirugías previas nasosinusales puede ser recomendable utilizar en ellos otro tipo de pruebas disponibles para diagnosticar la COVID-19.

This article explores how placemaking took place in architectural and design studios working with migrant and displaced communities at universities in three countries. Placemaking is a dimension of architectural and urban design practice that is emulated in architectural design studios – and often takes the form of a top-down and expert-driven exercise. In contrast, bottom-up placemaking is constituted through spontaneous and everyday practices in a given locality. The studios engaged with social scientists with a particular focus on displaced and immigrant communities. In Delhi, a multi-disciplinary social design studio at Ambedkar University applied community engagement and a service design approach to sustainable social interventions with a physical design component. At the University of Brighton, UK, an architectural design/build studio aimed at actual construction and transgressed the studio boundary to work closely with a charity supporting young refugees. In Norway, architecture students in an urbanism studio at the Oslo School of Architecture and Design surveyed an immigrant-dominated modernist housing district and proposed architectural and urban space interventions. Across the studios, student projects ranged from visualising futures to physical and social interventions. Learning outcomes varied, including design and planning skills, community engagement methods, co-design approaches and training in reflexivity. Venturing beyond the studio entailed engaging in sociocultural learning practices, engaging urban complexities and challenging expert authority and epistemologies in architecture and design education.
Estudio espectral de diferentes variedades de agave para la creación de una librería espectral para su mapeo y monitoreo mediante percepción remota
Authors: Corona-Romero Nirani , Coronado Juárez Erick , Madrigal Gómez José Manuel
Published: April 2022

El agave es una planta representativa de paisajes naturales y antrópicos de muchas regiones áridas y semiáridas de México y da gran cantidad de productos, entre ellos, el mezcal. Para su producción se emplean tanto magueyes silvestres como cultivados, por lo que su demanda en los mercados nacionales e internacionales han propiciado el cambio de uso de suelo para su cultivo y la erosión genética de sus poblaciones. Al no existir información sobre su ubicación y abundancia, no es posible elaborar planes de manejo que aseguren su permanencia. Por lo tanto, en este trabajo se presenta una librería espectral para A. angustifolia (espadín), A. americana var. Oaxacensis (arroqueño) y A. potatorum (tobalá) y otras coberturas asociadas al cultivo, así como la identificación, mediante la prueba no-paramétrica para muestras independientes de Kruskal-Wallis y la de Dunn, de las bandas de imágenes de Sentinel 2A donde la reflectancia de las firmas híperespectrales (350-2500 nm) de estos elementos es significativamente distinta para que puedan ser usadas para determinar su distribución espacial con estas imágenes, que fueron tomadas en tres localidades de Oaxaca, por un espectroradiómetro portátil. Los resultados apuntan a que mediante el uso de las bandas 2, 3, 6 y 8 es probable que puedan clasificarse tanto los agaves como sus coberturas asociadas.
Migrant Remittances Inspired Enterprises in Tsholotsho: Issues of Sustainability
Authors:   National University of Science and Technology, Maviza Gracious , Maphosa Mandlenkosi , Tshuma Nevel , Dube Zenzo , Dube Tomson
Published: April 2022

Following unprecedented and protracted political and economic crises during the period spanning 2000 to 2009, Zimbabwe experienced increased migration of its populace to the diaspora. One notable positive result of this migration phenomenon has been an increase in the inflows of remittances, which have partly inspired the emergence of enterprises. In February of 2009, Zimbabwe introduced the multi-currency system, which introduced new dynamics related to the sustainability of these enterprises. This, coupled with the foregoing, called for the review of the sustainability of remittance-inspired enterprises to ensure their potential for survival in the interim and the long term. As such, the present study was guided by a framework produced by the International Labour Organization (ILO), which lists the six basic conditions necessary for nurturing sustainable enterprises. This study made use of both primary and secondary data that included a household survey carried out on 40 households and 10 key informant interviews. In line with five of the six pillars of the ILO framework, the study found the following: 1) there is a governance framework instituted by the District Council that regulates the operations of businesses; 2) the infrastructure to support businesses is either not in place or is in a poor state; 3) enterprises practice responsible stewardship of the environment; 4) the society and culture is supportive of enterprise formation; and 5) the macro-economic environment is riddled with uncertainties.
Precarious Mobility: Infrastructures of Eritrean migration through the Sudan and the Sahara Desert
Authors:   Addis Ababa University, Mengiste Tekalign Ayalew
Published: April 2022

This paper explores migrants experiences and their specific practices geared towards negotiating migration barriers and the effects of externalization. Contemporary migration from Eritrea is shaped by changing migrant aspirations, expanding networks of intermediaries and socioeconomic challenges. This is compounded by the European Union's (EU) externalization of border controls and limited opportunities for legal migration paths. In this context, a vast majority of Eritrean young men and women opt for overland exits through dangerous and long trails across the Sahara Desert and the Mediterranean Sea until they arrive in Europe. The irregular transitions and stepwise mobility are facilitated by the interactions of actors, mainly smugglers, family members in one's homeland, former migrants en route and in the diaspora as well as the local people along the trails, which I call infrastructures of migratory mobility. The paper argues that migrants and their communities develop and use alternative mobility infrastructures by establishing a transnational knowledge community to navigate increasing migration controls in origin and transit countries, as well as the externalization of European borders and migratory controls.
Probing the Context of Vulnerability: Zimbabwean Migrant Women's Experiences of Accessing Public Health Care in South Africa
Authors: Mutambara Victoria M , Naidu Maheshvari
Published: April 2022

The economic meltdown and worsening levels of poverty in Zimbabwe led to a significant increase in the number of women migrating to South Africa from 2005 to 2010 (Crush et al., 2015: 367). A Southern African Migration Programme (SAMP) survey in 1997 found that 61% of Zimbabwean migrants were male and 39% were female (Crush et al., 2015: 367). This suggested that there was an increase in the number of women migrating to South Africa compared with other countries in Southern Africa. This gives us reason to speculate that the numbers could have increased a decade later because of the economic crisis that resulted in large numbers of people migrating out of Zimbabwe. Most Zimbabwean women are now moving across borders independently of their spouses and partners in search of better and sustainable livelihoods (Dzingirai et al., 2015: 13; Mbiyozo, 2019). Whilst some have valid immigration documents, a large number of these women are undocumented, which heightens their vulnerability to various structures of violence (Bloch, 2010;Rutherford, 2020: 172).

Calibration of soil moisture sensors, determination of soil water retention properties for precision irrigation based on soil water content measurements
Authors: ŽELEZNIKAR Špela , PEČAN Urša , HONZAK Luka , PINTAR Marina
Published: April 2022

Water is becoming a scarce commodity. Therefore, proper water management in precision irrigation is crucial to increase productivity and reduce the cost of crop production. Precision irrigation is based on measuring the soil water content, which is often measured with dielectric sensors that measure the apparent permittivity of the soil. Although the sensors are already equipped with a factory calibration function that converts the measured permittivity into volumetric water content, the function does not work properly for all soil types. It is therefore recommended to check whether a soil-specific calibration is required for accurate soil water content measurements. Precise irrigation also requires adequate determination of soil water retention properties, which can be determined using various procedures and methods. In this paper, we presented the results of applying different approaches to determine soil-specific calibration functions using two types of dielectric sensors (SM150T, Delta-T Devices and MVZ 100, Eltratec) in different soil samples obtained from locations in Slovenia where precision irrigation is performed. In addition, the results of determining the water retention properties of the soil using different methods were also compared.
Spatio-temporal analysis of East Asian seismic zones based on multifractal theory

Published: April 2022

In this article, the integrity of the seismic catalog obtained (1970–2014, M > 2.8) was verified according to the Gutenberg–Richter relation, the appropriate minimum magnitude was determined, and the whole region was divided into five areas according to the geological structure background of the whole research object and the trend of the historical seismic zone. We applied multifractal analysis in each partition. The results showed that although in different geological backgrounds, before major earthquakes, the earthquake time series information dimension had different degrees of growth, and the parameter after the flame had different degrees of decline. To a certain extent, this reflected the seismic energy accumulation and release process. In addition, the variation of fractal parameters in scale-free regions of time series and spatial distribution series also indicated that these two kinds of sequences in different regions show the characteristics of a multifractal structure rather than a single and uniform fractal structure.

lncRNA NONRATT013819.2 promotes transforming growth factor-β1-induced myofibroblastic transition of hepatic stellate cells by miR24-3p/lox
Authors: Guo Can-Jie , Pan Qin , Ma Xiong
Published: April 2022

Long noncoding RNAs (lncRNAs) are key regulators of hepatic stellate cells (HSCs), yet the role of upregulated lncRNA-NONRATT013819.2 in activated HSCs remains uncertain. In this study, the effects of NONRATT013819.2 on proliferation, apoptosis, migration, and contraction of transforming growth factor (TGF)-β1-induced HSCs were investigated. The mechanisms of NONRATT013819.2 on the activated HSCs were explored by loss-of-function of NONRATT013819.2 and gain-of-function of the target gene. Here, TGF-β1 treatment resulted in a gradual increase in the expression of cytoskeleton markers (collagen, α-SMA, and TIMP1), NONRATT013819.2, miR24-3p, and lysyl oxidase (Lox) over time in HSCs. NONRATT013819.2 acted as a sponge of miR24-3p to competitively abolish the inhibition of the lox gene in HSCs. Silencing of NONRATT013819.2 suppressed the expression of cytoskeleton markers, proliferation, and the proportion of cells that entered the S-phase, and promoted apoptosis in TGF-β1-activated HSCs. These effects were reversed when lox overexpression was introduced simultaneously. Similarly, silencing of NONRATT013819.2 also blocked ECM reconstruction, while recused by lox overexpression in TGF-β1-activated HSCs. In conclusion, upregulation of NONRATT013819.2 promotes the myofibroblastic transition by competitively binding miR24-3p to release lox in HSCs. Therefore, targeted therapy of NONRATT013819.2 may have the potential for liver fibrosis.

The prediction of Malaysian Borneo tide water level using a Chaotic approach
Authors: Mohd Ali Nazliah , Abd Hamid Nor Zila , Ishak Shahida
Published: April 2022

Predicting sea level is crucial since the rising of sea levels can cause flood, inundation and coastal erosion. This study investigates the potential of the chaotic model to forecast the future sea level in Malaysian Borneo (Sabah). The studied data is an hourly time series of water level collected at the particular benchmark location (station 74003) in the district of Sandakan, Sabah. This study employed 5136 time series data from June 2017 to November 2017. The research goals are to discover the existence of chaotic dynamics by reconstructing the multi-dimensional phase space and Cao method, and to predict future water level data using the local linear approximation approach. The outcome reveals that the correlation coefficient betwixt actual and forecasted data is 0.9228 which is close to 1. It thus reveals the reliability of the prediction method for forecasting the sea level time series data, as well as encouraging indication that the chaotic approach is appropriate to a time series of Malaysian sea level. In implication, these findings are expected to help agencies, particularly the Malaysian Department of Survey and Mapping (JUPEM), organise better sea-level management.
REGARDING THE USE OF BENTONITE CLAYS FROM THE CHERKASY DEPOSIT FOR SAFE RADIOACTIVE WASTE DISPOSAL IN NEAR-SURFACE LOW LEVEL WASTE STORAGE FACILTIES: RESEARCHES ON SORPTION PROPERTIES OF BENTONITES

The article is devoted to the study of the barrier properties of bentonite clays from the Cherkasy deposit (Ukraine) as the most promising material for engineered barriers in near-surface disposal facilities for low-level radioactive waste. The work presents a description of the Cherkasy bentonite deposit, in particular, of the most promising II layer of the Dashukivka site, and the composition and properties of the natural and soda-modified (PBA20) bentonites which can be used for safe long-term storage and disposal of radioactive waste. The scanning electron microscope (SEM) images of the samples were made and the chemical and mineral composition of the samples was determined. Based on the obtained data, the Dashukivka bentonite was classified as Al-Fe-montmorillonit. The main rock-forming minerals of the bentonite are montmorillonite (75 ± 3 wt. %) and quartz (20 - 25 wt. %). Infrared spectra of the bentonites in the range of 4000 - 400 cm-1 are typical for dioctahedral Al-smectites and are almost identical both for the natural and modified samples. The derivatographic analysis (DTA) of the bentonite samples allows us to conclude that the modified bentonite PBA-20 has greater thermal stability than the natural bentonite. The total weight loss of the samples is about 10.3% and 17.8%, respectively. From the experimental study of 137Cs adsorption from a simulated ChEZ water solution (mineralization – 0.2 g/dm3), it was found that the equilibrium in the sorbent-solution system is established within 12 to 14 h, and the degree of adsorption on the modified bentonite PBA-20 reaches 93%. The degree of adsorption on the natural bentonite is 7 - 10% lower. Analysis of the partition coefficients (Kd) also indicates a higher efficiency of the Na-modified bentonite compared to the natural, and that ion exchange is the main mechanism of caesium adsorption. Increasing of the pH of the initial solution results only in a slight increase of the degree of adsorption. The degree of 137Cs adsorption on Na-modified bentonite is practically independent of the initial concentration of Ca2+ (from 16 to 160 mg/dm3) and Na+ (from 6 to 60 mg/dm3) in the solution. However, 137Cs adsorption on natural bentonite decreases with the increase in Na+ concentration. Thus, the bentonite clays from the Cherkasy deposit (Dashukivka site, II layer) having good barrier properties can be recommend as anti-migration engineered barriers for radioactive waste repositories, in particular, near-surface storage facilities I and II line of Vector complex

People spend most of the time under artificial light sources, so it is important to create a comfortable lighting environment for work and rest. Four-component RGBW systems are the most effective for this. It is needed to create methods for obtaining white light with the specified parameters and choose the most optimal LED components. In this work, the influence of the white LEDs parameters on the resulting white light of the RGBW systems is studied. Two different methods proposed by us earlier for obtaining white light are applied for three RGBW systems with different warm white LEDs. It is shown that the use of white LEDs with a colour rendering index close to 80 is more optimal for most applications. In this case, they provide the resulting white light with the colour rendering index above 90 and luminous efficacy above 130 lm/W.

The process of dynamic spectral processing of optical radiation in the active electro-optical system that provides enhancement of the contrast of the image target has been experimentally researched. A routine of experiment and a diagram of an experimental setup have been developed. The sources of optical radiation in the transmitting part of the active electro-optical system were three semiconductor lasers operating in the ranges of the red, green, and blue spectral regions. Absorption optical filters were used in the experiment as the elements simulating the spectral properties of the reflecting surfaces of the target and the background. To enhance the contrast of the target image, the spectral composition of the laser radiation is formed to provide maximum suppression of the background signal with minimum attenuation of the optical signal of the object. When forming the spectral density of the laser radiation intensity, a priori information about the spectral characteristics of the target and the background has been used. The results obtained in the course of the experiment confirm the possibility to separate the target signal from the background interferences due to using the dynamic spectral processing of optical radiation in the active electro-optical system.

Considered in this paper are development and creation of high-power LED luminaires with high light efficiency and color rendering index (CRI). As light sources, there used are 6 powerful LED СОВ (Chip-on-Board) modules CreeCXA 2550, the radiation of which contains quasi-chromatic peaks in the spectral range 600…650 nm. It allows to provide CRI values higher than 92. Features of the improved compact construction of the luminaire with indicated COB modules have been presented. To ensure normal thermal regimes of LED COB modules, a small cooling system based on heat pipes has been created, the optimal dimensions of the structural elements of which have been determined by computer simulation. The results of modeling and experimental studies have shown that the developed and manufactured passive cooling system of LED COB modules provides operation temperature modes (up to 85 °C) of light-emitting crystals at the total electric power of COB modules up to 290 W and allows using the luminaires of this type in the systems of continuous artificial illumination with combined power supply. The efficiency of the developed cooling system at some angles to the horizon expands the scope of applying the illumination device.
PRAKTIK DAKWAH ONLINE DI MEDIA SOSIAL (STUDI KASUS PADA AKUN INSTAGRAM @KHALIDBASALAMAHOFFICIAL)
Authors: Kulsum Umi , Subhan Arief , Darajat Deden Mauli
Published: April 2022

Teknologi kerap dipandang negatif oleh kelompok agama karena dianggap bagian dari modernitas yang identik dengan sekularisme. Kehadiran praktik dakwah online di internet mematahkan anggapan ini. Dakwah online tidak sekedar sebagai ruang keberagamaan baru, namun juga mampu menunjukkan ekssitensinya sebagai gerakan sosial spiritual di ruang virtual. Salah satu praktik dakwah online yang memperoleh perhatian adalah akun dakwah kelompok Salafi @khalidbasalamahofficial. Studi ini ingin menjawab bagaimana praktik dakwah online pemuka agama dari kelompok Salafi di media sosial. Riset ini menggunakan perspektif religion online yang melihat bagaimana praktik agama di ruang nyata (offline) masuk kedalam ruang online. Menggunakan  pendekatan kualitatif, metode etnografi virtual, dan model level analisis media siber. Hasil penelitian menunjukkan bahwa dalam praktik dakwah online terjadi proses modifikasi atas praktik dakwah konvensional di ruang nyata. Pelaku dakwah tidak hanya sekadar memindahkan kajian konvensionalnya ke ruang virtual, namun juga mengubah cara mereka dalam mengemas pesan dan meraih jamaah. Dalam praktik online ada proses yang terorganisir dan terstruktur baik dalam penentuan konten, penyajian, maupun dalam merespons jamaah yang lebih interaktif dibanding pada praktik dakwah konvensional yang terbatas. Meski demikian, keberadaan teknologi sebatas sebagai saluran baru, tanpa mengubah substansi nilai yang melekat pada ajaran Salafi. Selain itu, riset ini menunjukkan bahwa ruang online telah membuka sekat dan kebebasan jamaah untuk merespons isi dakwah secara terbuka dan langsung. Kata Kunci: praktik dakwah online, new media, salafi, instagram, akun @khalidbasalamahofficial
