Groped and Gutted
Authors: Eddy Samantha
Published: September 2020

The realm of horror provides a creative space in which the breakdown of social order can either expose power relations or further cement them by having them persist after the collapse. Carol Clover proposed that the 1970s slasher film genre—known for its sex and gore fanfare—provided feminist identification through its “final girl” indie invention. Over three decades later, with the genre now commercialized, this research exposes the reality of sexual and horrific imagery within the Hollywood mainstay. Using a mixed-methods approach, I develop four categories of depiction across cisgender representation in these films: violent, sexual, sexually violent, and postmortem. I explore the ways in which a white, heterosexist imagination has appropriated this once productive genre through the violent treatment of bodies. This exposes the means by which hegemonic, oppressive structures assimilate and sanitize counter-media. This article provides an important discussion on how counterculture is transformed in capital systems and then used to uphold the very structures it seeks to confront. The result of such assimilation is the violent treatment and stereotyping of marginalized identities in which creative efforts now pursue new means of brutalization and dehumanization.

System effects of lowered district heating supply temperatures
Authors: Lidberg Tina , Olofsson Thomas , Ödlund Louise
Published: September 2020

Lowering temperature levels of a district heating (DH) system may offer several advantages such as reduced distribution losses, increased efficiency of flue gas condensation equipment and increased electricity generation in combined heat and power plants. In a broader perspective this can result in more efficient use of natural resources as well as reduced climate-impacting emissions. This study examines how decreased DH supply temperatures influence the power-to-heat ratio and thereby electricity production and fuel use in a combined heat and power plant. Carbon dioxide equivalent (CO2-eqv.) emissions and primary energy use were calculated with three different marginal electricity perspectives. A regional DH system situated in mid-Sweden was used as a case study and the energy system cost optimization modelling tool MODEST (Model for Optimization of Dynamic Energy Systems with Time-Dependent Components and Boundary Conditions) was used. The results show that decreasing the DH supply temperature results in increased electricity production as well as increased fuel use within the system. Further, there is a significant difference in CO2-eqv. emissions and primary energy use for the studied marginal electricity perspectives.
Economics of reviving D.V.C. water supply canal amidst running supply to meet requirement of city of Durgapur, India
Authors: Dwivedi Vijay Kumar , Ghosh Snigdhadip
Published: September 2020

A water supply canal having a length of 8.9 km, originating from Durgapur Barrage at Durgapur, West Bengal, India and terminating in a pool at a downstream distance of 8.9 km was constructed by Damodar Valley Corporation during 1957-60 to supply drinking water to the city of Durgapur, West Bengal, India and water to several industries situated at Durgapur. Durgapur Municipal Corporation withdraws its complete demand from this canal of DVC. The major industries withdrawing water from the canal is M/S Durgapur Chemical Limited, M/S Durgapur Steel Plant, M/S Phillips Carbon, M/S Durgapur Thermal Power Station. Though the canal was designed for original capacity of 900 cusecs, but now there is withdrawal of about 400 cusecs only from the canal due collapse of the cross section of the earthen canal at different chainage, silting of the canal throughout its reach resulting in failure of the function of the canal to supply water to major customers. A study was undertaken to assess the present hydraulic and environmental conditions of the existing canal and propose procedure for revival of the canal in the most economic way without disrupting the present withdrawal from the canal and also suggest measures to be undertaken for maintenance of environment along the canal to prevent canal cross section from unlawful ingress of water into the canal. In this study, present hydraulic conditions of the canal have been analyzed. Different alternatives of reviving the canal to carry a discharge of 500 cusecs were attempted by (i) designing pre-cast section of the canal capable of carrying a discharge more than 500 cusec, (ii) simply using the existing cross section with side protection with steel sheet piling and bottom protection with concrete blocks, and (iii) providing diaphragm wall on each side of the section and bottom protection with concrete blocks. Feasibility of construction under conditions of continued supply to the existing stake holders was considered while analyzing the economics of revival for all the three alternatives. Revival of the canal by option (ii) has been recommended on the basis of economics of revival amid running condition of the canal. Though the working life of the canal with sheet pile protected side wall is less than that of the canal with diaphragm wall as the side wall of the cross section but workability under running condition of the canal is much higher for the case of side protection with steel sheet piles. Measures such as diverting the unlawful ingress away from the canal, protecting the side berms with green cover has been recommended to improve the environment around the canal.

A Low Quantum Cost Implementation of Reversible Binary-Coded-Decimal Adder
Authors: Thabah Sheba Diamond , Saha Prabir
Published: September 2020

The prediction and forthcoming of a quantum computer into the real-world is the much gained research area over the last decades, which initiated the usefulness and profit of reversible computation because of its potentiality to reduce power consumption in designing arithmetic circuits. In this paper, two design approaches are proposed for the design of a reversible Binary-Coded-Decimal adder. The first approach is implemented and realized from reversible gates proposed by researchers in the technical literature capable of breaking down into primitive quantum gates, whereas the second approach is realized from the existing synthesizable reversible gates only. Parallel implementations of such circuits have been carried out through the proper selection and arrangements of the gates to improve the reversible performance parameters. The proposed design approaches offer a low quantum cost along-with lower delay and hardware complexity for any n-digit addition. Analysis results of proposed design 1 show appreciable improvements over gate count, quantum cost, and delay by at least 9 %, 17 %, and 26 % respectively, whereas, the proposed design 2 show that the results significantly improve the parameters (gate count, quantum cost, and delay) by at least 45 %, 33 %, and 50 % respectively compared to existing counterparts found in the literature.

Published: September 2020

To evaluate the adaptability and stability of silage maize cultivars and identify the representativeness and discrimination of each testing site, a two-year field research in a randomized complete block design (RCBD) with three replicates at 10 testing sites was conducted. An additive main effect and multiplicative interaction (AMMI) model and a genotype plus genotype environment interactions (GEI) biplot (referred to as GGE hereafter) were used to analyze the data. The two-year test revealed that four cultivars (Zhongdi 175 (ZD175), Qiushuo 008 (Q008), Hengyu 1587 (H1587), and Yayuqingzhu 8 (Y8) exhibited high yield and good stability, whereas two cultivars (Zhongbeiqingzhu 410 (Z410) and Fangyu 36 (F36) had low yield and poor stability. The comprehensive application of the AMMI model and the GGE biplot could accurately and intuitively evaluate the high yield, stability, and adaptability of each cultivar.
Optimum vegetative growth conditions and genetic diversity in different strains of Pleurotus salmoneastramineus L.J.N. Vassilzeva
Authors: Alam Nuhu , Rahman Farhana
Published: September 2020

This experiment was undertaken to depict the favourable condition for mycelial growth, molecular identification and phylogenetic relationship of the selected strains of Pleurotus salmoneostramineus. Suitable temperature and pH were obtained at 25ºC and 6, respectively. Mushroom complete, glucose peptone and yeast malt extract culture media were favorable, while Hennerberg and Hoppkins were unfavorable. Dextrin was the best and xylose was the less effective carbon sources. Inorganic nitrogen sources were less effective for the mycelial growth of P. salmoneostramineus. The sequences of internal transcribed spacer (ITS) region of selected strains revealed that the total length ranged from 614 to 663 bp. The size of the ITS1 and ITS2 regions varied among the strains. Sequence analysis showed that 5.8S of rDNA sequences were identical. Phylogenetic tree of the ITS region sequences indicated that strains of P. salmoneostramineus belong to same cluster. The reciprocal homologies of the ITS region sequences ranged from 98 to 100%. The strains of P. salmoneostramineus were also analyzed by random amplification of polymorphic DNA (RAPD) with 20 arbitrary primers. RAPD results suggested that tested strains of P. salmoneostramineus were genetically similar with some variations, thus it could be concluded that RAPD and ITS techniques were well competent for detecting the genetic diversity of all tested strains of P. salmoneostramineus.

Oil Price Shocks and Macroeconomic Dynamics in an Oil-Exporting Emerging Economy: A New Keynesian DSGE Approach
Authors: Oladunni Sunday
Published: September 2020

The global oil dynamics has significant implications for both oil exporting and importing small open economies. However, much of the literature on oil shocks is oriented towards advanced oil-importing economies. Micro-founded studies that explore the effects of oil shocks from the standpoint of oil-endowed emerging economies are rather sparse, compared to the preponderance of studies on developed oil importers and exporters. Thus, resulting to a consequential knowledge gap on oil price transmission mechanism and a limited appreciation of the growing policy dilemmas in these economies. The paper, therefore, sets up a new Keynesian dynamic stochastic general equilibrium (DSGE) model to study how an oil price shock impacts on macroeconomic aggregates in an oil-rich emerging economy. We consider a positive oil price shock to uncover the extent to which oil price increase is positive for the economy. The typical small open economy model is enriched with an export-oriented oil firm, a multi-sector foreign production and a non-oil domestic firm. The model is closed with exchange rate-augmented interest rate rule, and it is calibrated for Nigeria, an important oil producer. Macroeconomic responses, sequel to a simulated positive oil price shock, reveal evidence of Dutch disease and the operation of the Harrod-Balassa-Samuelson effect. We find a compelling need for oil-endowed emerging economies to address these phenomena by ensuring a robust non-oil sector
with limited exposure to the vagaries of oil price oscillation.

Cooperative learning is not only about studying and sitting together, but it is more about structuring the group work. Structuring group work includes guidance of step by step to do the assignment. In the assessment process of group work, teachers tend to assess students individually, which is disassociated. To bridge the gap, representativeness assessment is introduced as a current insight. This study aimed to identify student’s perception toward cooperative group work strategies and representative assessment. In this research, data were collected through questionnaires from a population of students. The result of the study showed that the respondents showed high percentage of perception on both cooperative group work strategies and representative assessment.
THE INSEPARABLE NARRATOLOGY AND GENRE IN DISNEY’S ALADDIN (2019): A STRUCTURALIST CRITICISM
Authors: Hamim Sandi
Published: September 2020

The current study aims to analyze the narratology and to identify the genre of Disney’s Aladdin (2019). It also discusses the relationship between narratology and the genre in the movie. The theories used in this study are narratology theory by Vladimir Propp and genre analysis by Northrop Frye with the structuralist criticism perspective. The study used the descriptive qualitative method. The findings of this study provide pieces of evidence that Disney’s Aladdin movie can be analyzed using Propp’s narratology. There are 30 of 31 functions of dramatis personae and 7 of 7 dramatis personae found in the movie. Those findings are deducted by focusing on the plot and characters in the movie. According to those findings, the genre of the movie based on Frye’s theory of myths is the mythos of spring (comedy). This is because the movie moves from the mythos of winter to summer (irony to romance). This finding is supported by the existence of the elements of conflict, disorder and confusion, and the triumph of traditional quest theory. It also supported by the existence of the category of irony, romance, and comedy (theory of modes in the movie. Hence, the researcher deduces that the narratological analysis and the genre in this study are intercorrelated and support one another.

Around 176500 whales were killed in the sub-Antarctic waters off South Georgia (South Atlantic) between 1904 and 1965. In recent decades, whales have once again become summer visitors, with the southern right whale (SRW) the most commonly reported species until 2011. Here, we assess the distribution, temporal pattern, health status and likely prey of SRWs in these waters, combining observations from a summertime vessel-based expedition to South Georgia, stable isotope data collected from SRWs and putative prey and sightings reports collated by the South Georgia Museum. The expedition used directional acoustics and visual surveys to localise whales and collected skin biopsies and photo-IDs. During 76 h of visual observation effort over 19 expedition days, SRWs were encountered 15 times (~31 individuals). Photo-IDs, combined with publicly contributed images from commercial vessels, were reconciled and quality-controlled to form a catalogue of 6 fully (i.e. both sides) identified SRWs and 26 SRWs identified by either left or right sides. No photo-ID matches were found with lower-latitude calving grounds, but 3 whales had gull lesions supporting a direct link with Península Valdés, Argentina. The isotopic position of SRWs in the South Georgia food web suggests feeding on a combination of copepod and krill species. Opportunistic reports of SRW sightings and associated group sizes remain steady over time, while humpback whales provide a strong contrast, with increased sighting rates and group sizes seen since 2013. These data suggest a plateau in SRWs and an increasing humpback whale presence in South Georgia waters following the cessation of whaling.

Published: September 2020

Dolphins are among the largest and most diverse predators in marine ecosystems, but our understanding of their foraging ecology, which is crucial for ecosystem management, is poor. Delphinus delphis (common dolphins) are found in tropical and temperate waters globally. Stomach content studies indicate they are opportunistic predators that feed locally on abundant small pelagic schooling fish, but information is lacking on how their diet may vary seasonally and with ontogeny. We investigated effects of body length, sex, season, and year on D. delphis diet in the Hauraki Gulf, New Zealand, using carbon (δ13C) and nitrogen (δ15N) stable isotope analysis of 56 skin samples collected during 13 years (2004-2016). Dolphin δ15N values changed with body length, suggesting ontogenetic dietary variation. Nitrogen isotope values were higher in austral autumn/winter compared to spring/summer, whilst δ13C values decreased throughout the study period, suggesting temporal changes in primary productivity likely affecting the dolphins’ diet. Sex had a minor effect on dolphin δ13C values, with male and female isotopic niches overlapping by 62.6% and 45.2% (respectively). Our results provide a baseline for detecting future changes in the trophic ecology of D. delphis in a key habitat in New Zealand and highlight their role as a sentinel species in this coastal ecosystem.
Global climate changes over time shape the environmental niche distribution of Octopus insularis in the Atlantic Ocean
Authors: Lima FD , Ángeles-González LE , Leite TS , Lima SMQ
Published: September 2020

In the Atlantic Ocean, Octopus insularis (Cephalopoda: Octopodidae) Leite and Haimovici, 2008 inhabits warm and shallow habitats, where it is one of the main targets of cephalopod fisheries. Considering the current trend of increasing seawater temperature, warm-water species are expected to expand their geographic distribution ranges. Ecological niche modeling (ENM) is an important tool to help describe likely changes in geographic distribution patterns of a species in different climatic scenarios. To evaluate changes in the distribution of Octopus insularis over time, the maximum entropy approach was used, which estimated a suitable climatic niche for Octopus under 5 scenarios of global climate change. Four environmental variables were chosen to model the suitable climatic niche of O. insularis in the present, past, and future scenarios. The ENM in different climatic scenarios showed good validation and pointed out an increase of the suitable niche for O. insularis settlement, from the Last Glacial Maximum (21 kya) up to future scenarios. In the future projections, suitable niche space will potentially increase in the tropical Atlantic compared to the current distribution. Modeling pointed out the possibility of expansion from the current range of the species to the temperate northern Atlantic, temperate South America, and temperate South Africa. This may cause potential threats, such as possible extinction of endemic species, habitat displacement of native octopuses, and reorganizations in the trophic chain.
Features of the Problem of Socio-Demographic Processes of the Population in the Kashkadarya and Surkhandarya Oases (late 19th century)
Authors: Xolmuminov X.
Published: September 2020

This article presents a scientific analysis of the problems of the socio-economic way of life and demographic processes of the population of the Kashkadarya and Surkhandarya oases and their features in the late 19th centuries. The administrative centers experienced an increase in population and ethnic composition, but in rural areas their standard of living was significantly higher. An analysis of demographic processes shows that the population of this southern region accelerated the transition to a more sedentary lifestyle during this period. As a result of these factors, the population of the cities, which were the administrative centers in the southern oases, gradually increased, and gradually commercial and industrial enterprises appeared. In conclusion, it is concluded that there were still many problems in the demographic processes of the social life of the population in the principalities of the southern oases.

Hypertension with inadequate treatment will cause complications which is the number fifth cause of death in all ages. In order to avoid complications, family support was required to treat hypertension. OBJECTIVE: To determine the relationship between family support and caring behavior of hypertension by families at homeMETHODS: Correlational research design with cross sectional approach was used. A sample of 35 respondents willing to join by simple random sampling. Chi-Square Test was used to analyze the data. RESULTS: There was a significant relationship between family support and caring behavior of hypertension by families at home with value p-value = 0,003. While the domain of family support which related to the caring behavior of hypertension are instrumental support (p-value = 0,001), informational support (p-value = 0,000) and emotional support (p-value = 0,004). Finally, it can be concluded that family support have to be considered in treating hypertension at home.Keywords:  caring behavior, family support, hypertension
Experimental Research on the Hysteretic Behaviour of Pressurized Artificial Muscles Made from Elastomers with Aramid Fibre Insertions
Authors: Filip Ovidiu , Deaconescu Andrea , Deaconescu Tudor
Published: September 2020

Inherent hysteresis behaviour of pressurized artificial muscles is complicated to understand and handle, calling for experimental research that allows the modelling of this phenomenon. The paper presents the results of the experimental study of the hysteretic behaviour of a small-size pneumatic muscle. The specific hysteresis loops were revealed by isotonic and isometric tests. Starting from hypothesis according to that the tube used for the pneumatic muscle is made entirely of aramid fibres enveloped by an elastomer material that merely ensures their airtightness, the paper presents the hysteresis curves that describe the radial and axial dimensional modifications as well as the variation of the developed forces for different feed pressures. The obtained third-degree polynomial equations underlie the configuration of high-performance positioning systems.
Low-Cost, Open-Source Mechanical Ventilator with Pulmonary Monitoring for COVID-19 Patients
Authors: Acho Leonardo , Vargas Alessandro N. , Pujol-Vázquez Gisela
Published: September 2020

This paper shows the construction of a low-cost, open-source mechanical ventilator. The motivation for constructing this kind of ventilator comes from the worldwide shortage of mechanical ventilators for treating COVID-19 patients—the COVID-19 pandemic has been striking hard in some regions, especially the deprived ones. Constructing a low-cost, open-source mechanical ventilator aims to mitigate the effects of this shortage on those regions. The equipment documented here employs commercial spare parts only. This paper also shows a numerical method for monitoring the patients’ pulmonary condition. The method considers pressure measurements from the inspiratory limb and alerts clinicians in real-time whether the patient is under a healthy or unhealthy situation. Experiments carried out in the laboratory that had emulated healthy and unhealthy patients illustrate the potential benefits of the derived mechanical ventilator.
The Effects of Hackathons on the Entrepreneurial Skillset and Perceived Self-Efficacy as Factors Shaping Entrepreneurial Intentions
Authors: Szymanska Izabela , Sesti Tom , Motley Hali , Puia George
Published: September 2020

Purpose: While traditional university programs primarily use regularly scheduled classes as the primary means for developing students, this program evaluation explores the direct effects of intensive entrepreneurial learning activity in the format of a hackathon. This is one of the first papers to explore the learning outcomes of hackathons as an intensive entrepreneurial pedagogy. Design/methodology/approach: The researchers implemented a pre-test/post-test model with students participating in an entrepreneurship hackathon and tested the changes in their confidence levels in the ability to craft a successful entrepreneurial venture. Findings: The results support a hackathon model of entrepreneurial learning. As the result of a one-day workshop, significant results were achieved for self-reported ability in identifying a viable entrepreneurial concept, and for having the ability to successfully launch a new venture. Further, class standing and prior entrepreneurial courses, as well as gender did not influence the learning outcomes. Importantly, while hackathon-generated increases in entrepreneurial self-efficacy proved to be statistically significant, same gains proved not to be significant in a traditional entrepreneurship class setting. Authors conclude that short, intensive entrepreneurship learning methods like hackathons may be more effective in developing entrepreneurial self-efficacy than semester long courses. Originality/value: A hackathon is likely an effective entrepreneurial learning methodology suitable for a general student population which includes students with limited knowledge of and interest in entrepreneurship. The usefulness of a hackathon for entrepreneurial learning has potential implications for educators, scholars and policy makers. For educators, a hackathon approach may outperform a number of traditional entrepreneurship pedagogies in the form of lectures, case studies, class discussions or even a business plan development over a semester-long course. A hackathon may also allow students to gain entrepreneurial skills and self-confidence much quicker and using less resources than in a traditional entrepreneurial course. The potential reasons for these findings as well as their implications are discussed along with future research areas.
Effect of Tillage Systems on the Yield and Quality of Winter Wheat Grain and Soil Properties
Authors: Woźniak Andrzej , Rachoń Leszek
Published: September 2020

This study aimed to evaluate the yield and quality of winter wheat grain and soil properties in three tillage systems (TS): (1) Conventional (CT), (2) reduced (RT), and (3) no-tillage (NT). In the CT system, shallow ploughing (at a depth of 10–12 cm from soil surface) and pre-sow ploughing (at a depth of 18–22 cm from soil surface) were performed after the harvest of the previous crop (peas). In the RT system, the shallow ploughing was replaced by field cultivation, whereas pre-sow ploughing was by a tillage unit. In the NT system, a herbicide treatment with glyphosate (4 L ha−1) replaced the ploughing measures, whereas a tillage unit including a cultivator, a string roller, and a harrow was used before wheat sowing. Higher wheat yields were recorded in CT than in NT (by 4.3%) and in 2016 compared to 2015 (by 23.4%). The tillage system differentiated spike number m−2, whereas study years affected spike number m−2, grain weight per spike, and 1000 grain weight. Study years also influenced all quality traits of the grain, whereas tillage systems—only grain uniformity and ash content of the grain. A less uniform grain with a higher ash content was produced in NT than in CT and RT systems. Organic C content in the soil was higher in NT than in CT and RT systems. In turn, total nitrogen and phosphorus contents were higher in the soil from NT and RT than CT, whereas potassium and magnesium contents—in RT and NT compared to the CT system.
