Published: November 2021

Summary
Allelopathic effects of different plant allelochemicals have become the focus of studies that aim to determine new pesticidal compounds. Plant extracts with different chemical compositions can be obtained using different methods of extraction, whereas studies dealing with allelopathic properties use biotests to obtain fast and precise results. Such studies were undertaken after noticing the allelopathic effects of industrial hemp (Cannabis sativa L.) on the surrounding crops. Trials that involve the application of hemp extracts obtained by different methods resulted in determining the hemp allelopathic effects on Stellaria media (L.)Scop., Beta vulgaris ssp. vulgaris var. vulgaris, Lupinus albus L., corn (Zea mays L.), Cyperus rotundus L., Matricaria recutita L., Lepidium sativum L., lettuce (Lactuca sativa L.), rapeseed (Brassica napus L.), wheat (Triticum aestivum L.), rye (Secale cereal M. Bieb.), Ambrosia artemisiifolia L., Chenopodium album L., and Sorghum halepense L..

Authors: Stamenov Dragana , Đurić Simonida , Jafari Timea Hajnal 
Published: November 2021

Summary
The objective of the present paper was to isolate microorganisms (Pseudomonas sp., Bacillus sp. and Azotobacter sp.) from the rhizospheric soil of rosemary (Rosmarinus officinalis L.) and investigate their biostimulatory (plant growth-promoting – PGP) and biocontrol potential. The bacteria isolated from the rhizosphere of rosemary included 15 bacteria of the genus Pseudomonas, 20 of the genus Bacillus, and 11 of the genus Azotobacter. Based on the morphological characteristics of colonies and cells, representative isolates of each genus were chosen (marked as Pseudomonas sp. P42, P43, P44; for Bacillus isolates B83, B84, B85, B92, B93; and for Azotobacter isolates A15 and A16) for different physiological and biochemical examination. The study included in vitro screening of the bacterial isolates for their PGP and biocontrol properties. Pseudomonas isolates showed the ability to live at low temperature (10ºC) and high pH (9), and to use different sources of carbon. All Pseudomonas isolates produced lipase, siderophore, hydrogen cyanide, and utilized organic and inorganic phosphorus, while only isolate P42 produced amylase, pectinase and cellulase. Only Bacillus isolates could grow at 45 ºC (all Bacillus isolates), pH 5 (isolates B83), and on a medium containing NaCl 5 and 7% (all isolates). Isolates denoted as B83 and B93 produced lipase, amylase, and pectinase. All isolates had the ability to solubilize phosphate, produce siderophores (except B85) and hydrogen cyanide, while only two isolates (B84 and B85) produced IAA. Azotobacter isolates had the optimal growth at 37ºC and minimal growth on a medium with pH 6 and 9. All Azotobacter isolates used all carbohydrates as a source of carbon and produced lipase, amylase, and hydrogen cyanide. The best result in suppressing the growth of pathogenic fungi Fusarium oxysporum was achieved by using isolate B92. Application of isolate B83 led to the greatest growth suppression of Sclerotinium sclerotiorum.

Published: November 2021

Summary
The purpose of this study is to assess the repellent activity of lemongrass (Cymbopogon citratus) essential oil (EO), grown in Serbia under greenhouse conditions, against four prevalent stored product pests: Plodia interpunctella (larvae), Sitophilus oryzae, Acanthoscelides obtectus and Tribolium castaneum (adults). The lemongrass EO repellency was tested using filter paper in Petri dishes and a Y-tube olfactometer. According to the repellency index (RI), the lemongrass EO repellency was divided into 5 classes. Prior to biotesting, the chemical characterization of lemongrass EO was performed and the following main compounds were detected: myrcene (31.0%), geranial (30.0%), and neral (23.6%). The C. citratus EO considered was found to exhibit the Class III repellent activity against P. interpunctella larvae only at the highest concentration (namely 0.5%). This is the very first report on the C. citratus EO repellent activity against this pest. The lemongrass EO examined showed strong repellency (Class IV) against S. oryzae (0.2% and 0.5% of EO), A. obtectus (0.1% and 0.2%), and T. castaneum (0.05-0.1%). Moreover, higher lemongrass EO concentrations (0.5%) were found to exhibit extreme repellency (Class V) against A. obtectus and T. castaneum. The results obtained were confirmed in the bioassays performed, indicating the great potential of lemongrass EO as a bio-repellent when applied in higher concentrations to all the insects considered, regardless of the exposure period.
“The Story is My Life”: Bridging Symbol to Self in a Novel Creative and Reflective Writing Task
Authors: Lang Jacob , Cupchik Gerald C. 
Published: November 2021

Abstract
This article describes the development and testing of a novel creative and reflective writing task. Following the rationale of sand-tray and play therapies, participants were asked to meaningfully incorporate four objects from a randomly generated matrix of options into a creative short story. They then composed a second story that incorporated four possessions from home associated with important memories. Afterwards, participants produced interpretive statements or reflections on what the stories meant to them. An exploratory qualitative study was conducted based on narrative data from 15 young adult participants in Canada. Our goals were to: (a) explore the extent to which object familiarity was associated with qualitative differences in stories and interpretations, and (b) investigate for connections between features of participants’ stories and depth of interpretation. Analysis of creative stories resulted in a scheme of four response categories with ten subcategories. Participants’ interpretations of their own stories were coded based on self-described sources of inspiration, such as critical life episodes or popular media. Results are accompanied with excerpts of participants’ stories and reflections, and percentage comparisons are reported. Findings are presented in dialogue with established interpretive frameworks originating in depth psychology. Manipulation of object familiarity resulted in demonstrable differences at the levels of word length, point of view, narrative forms and features, self-disclosure, and reflection. Use of familiar objects in such a task appears to be a largely untapped resource that shows promise as a route to insight.
Collaborative Musical Creativity between Students and Adults: The Sonorous Paella
Authors: Murillo Adolf , Riaño María Elena , Bautista Alfredo 
Published: November 2021

Abstract
While creativity is a key element of contemporary curriculum frameworks around the world, it is still insufficiently fostered in formal education settings. This study analyzes a project for collaborative musical creativity, entitled The Sonorous Paella. Participants (N = 12) were eight Year 4 secondary students, two professional musicians, an artist-in-residence, and a music teacher. Drawing on a graphic musical score, the participants worked together for 1.5 months to produce a group composition and performance. They were provided with various sound producers (instruments, everyday objects, technological devices) and were encouraged to flexibly utilize the physical space to maximize collaborative participation. Field notes and pictures taken during working sessions and rehearsals, audio recordings from the final concert, and individual interviews with all participants were qualitatively analyzed. In response to the three study objectives, we conclude that: (1) the design of this collaborative project was consistent with current research-based creativity discourses; (2) drawing on the quality and originality of the final concert, the project fostered the musical creativity of the group; and (3) participants’ perceptions of and opinions about their creativity learning processes were unanimously positive. Our final aim is to inspire music teachers in designing curriculum units that foster collaborative musical creativity.
Spreading one’s Wings, Milestones, Deus ex Machina: Self-creation as a Process of Changing Your Life with the Examples of Narrations Provided by Women
Authors: Chmielińska Aleksandra , Modrzejewska-Świgulska Monika 
Published: November 2021

Abstract
This paper presents narrative-biographic research conducted with participation of women who declare that they have introduced important changes into their lives. The qualitative data was collected using narrative interviews as well as a tool to examine changes in the biographic perspective; namely, Line of life. In the presented paper, the authors reconstructed biographical self-creation, meaning the ways of life in which important changes are a central category of a story about life. The authors reconstruct three different ways of narrators’ lives – “spreading one’s wings,” “milestones,” “deus ex machina,” and a case study that describes the process of self-creation and introduction of important changes into a life in more detail.
Automated Monsters of Vengeance: Comparing Goddesses in Ancient Greece and Hindu India
Authors: Nuckolls Charles W. 
Published: November 2021

Abstract
Monsters that act “automatically,” without thought or conscious awareness, constitute a category whose primary exemplar in American culture is the zombie. However, automaticity can be found in other realizations of the monstrous, including in ancient Greece and contemporary India. This paper compares the two. In Greece, the beings known as Eryines hunt and attack people who are guilty of crimes against members of their own kin group. One of the best examples is Orestes, whom the Erinyes pursue relentlessly because he killed his own mother, Clytemnestra. On the southeastern coast of India, among members of the Jalari fishing caste, there is a spirit called Sati Polalmma, who, like the Erinyes, attacks those who have broken oaths made to kin, especially oaths that concern sexual fidelity. The Erinyes and Sati Polamma are chthonic beings, associated with the earth, and are said to predate the patriarchal order of male deities. The paper explores automatic action as a characteristic of one category of the monstrous.
Monsters, Disaster, and Organic Balance: Digesting History Through Oral Traditions
Authors: Veyrié Thierry 
Published: November 2021

Abstract
This paper examines “Coyote, Whirlwind, and Ravine,” a long tale told in the Northern Paiute language by McDermitt storyteller Pete Snapp and recorded by folklorist Sven Liljeblad in the early 1960’s. It weaves in traditional episodes of western Numic folklore to narrate the history of the Fort McDermitt Paiute-Shoshone community as witnessed by an elder born shortly after the beginning of the colonization of this area of the Northwestern Great Basin in the western United States. This paper explores how the bodies of certain characters who emanate from landscape, mainly monsters, are tools for the narrative expression of social change, for the telling of history, and the expression of Indigenous spiritual frameworks. It places the experience of the Indigenous social body, embodied by Coyote, through the grinds of the ultra-material Ravine and confronts it to ethereal nefarious powers. Poetics of materiality applied to the body of Coyote operate a structural transformation. Mythical turmoil expresses social experiences and change in the colonial context, but also makes manifest the transformation of the social body that result in the contemporary form of the Fort McDermitt Paiute-Shoshone community.
“With All The Ghosts that Haunt the Park...”: Haunted Recreation in Brent (Ontario)
Authors: Puppe Ian 
Published: November 2021

Abstract
When I first visited Brent, the defunct logging village, now campgrounds in the northern reaches of Algonquin Provincial Park I went searching for ghost stories. Often described as a “ghost town,” Brent has been occupied since the earliest days of logging in the Ottawa River/Kiji Sibi Valley and holds an important place in the oral history of the Park. The village was a place where many died after violent accidents during the timber rush of the eighteen-hundreds, where Algonquin Anishinaabe Peoples had camped and likely held a village of their own prior to colonization. Brent was once a bustling community, the former site of the Kish-Kaduk Lodge and an important railway stopover during the First World War. Further, Brent was home to the last year round resident of the Park. Mr. Adam Pitts, known to many local cottagers as the “Mayor” passed away in his home in 1998 one year after the railroad tracks were removed by the Canadian National Railway Company and the electricity was shut off. Now his cottage is a ruin some claim to be haunted by the Mayor’s restless ghost. And there are other ghost stories I heard in Brent that haunt the edges of the colonial imagination, stalking unwary travellers as they meander through what they sometimes assume to be “pristine wilderness.” Common patterns of self-apprehension and identity formation associated with tourism and heritage management in Algonquin Park are imbued with nationalist value through a prismatic complex of cultural appropriation, the denial of complicity in colonial violence, and the contingent obfuscation of Indigenous presence and persistence in the area, a process I call haunted recreation. Countering this complex is critical for working past the historical and intergenerational trauma associated with Canadian settler-colonialism and the contemporary inequities of Canadian society.
Growing Appetites and Hungry Subjects: Addicts, the Undead, and the Long Arc of Theory in Western Social Science
Authors: Saris A. Jamie 
Published: November 2021

Abstract
This paper explores the Western philosophical idea of “appetites” through the lens of “addiction.” I begin with a brief ethnographic description of a woman whose subjectivity seems to emerge only in the play of her unmanageable desire for various pharmaceuticals. In other words, she is a self-described “addict.” I then look at the relationships between addicts and the undead, especially vampires and zombies, who are seemingly enslaved to their appetites. This leads me to an analysis of the centrality of what I am calling “recursive need satisfaction” in much of Western (especially Anglophone and Francophone) Social Theory that, I argue, relies on a particular understanding of “appetite” in establishing the political-economic subjectivity that lies at the heart of market-oriented state. This same understanding also pushes this formation in a specific historical direction of increasing growth and organisational and technological complexity. As a globalised Western society in the last few decades has become ever more anxious of its place in the world, its impact on various interdependent systems, and the validity of the grand récits that served as its charter, such growth and complexity have emerged as objects of anxiety, even apocalyptic fear, and the terms “addict” and “addiction” have seemed ever more useful for modelling these concerns. I end with some reflections on how we use both zombies and addicts to think through some of the same issues of unchecked and damaging consumption.

Published: November 2021

Abstract
The wireless connection distance between the transmission and reception coils of printed circuit boards (PCB) influences the mutual inductance and affects circuit performance. In this study, the mutual inductance M of PCB coils was investigated, and two analytical methods were presented for calculating the mutual inductance between two coaxial rectangular planar PCB coils incorporating magnetic layer. The results were acquired through calculations by using the Neumann integral and Biot-Savart methods. The complete integral calculations and detailed demonstrations of the two methods are presented. The obtained formulas were introduced in some examples of coils with different number of turns. The analytical and experimental results were compared, and a strong agreement between them was observed.
Estimation of parameters of a sum of sinusoids sampled below the Nyquist rate with frequencies away from the grid
Authors: Djurović Igor 
Published: November 2021

Abstract
We are witnessing a growing interest in processing signals sampled below the Nyquist rate. The main limitation of current approaches considering estimation of multicomponent sinusoids parameters is the assumption of frequencies on the frequency grid. The sinusoids away from the frequency grid are considered in this paper. The proposed procedure has three stages. In the first two, a rough estimation of signal components is performed while in the third refinement in estimation is achieved in a component-by-component manner. We have tested the developed technique on an extended set of simulation examples showing excellent accuracy. Three scenarios are considered in experiments: missing samples, noisy environment, and non-uniform sampling below the Nyquist rate.

Published: November 2021

Abstract
The growing demand for enhanced capacities, broadband services, and high transmission speeds to accommodate speech, image, multimedia, and data communication simultaneously puts a requirement for antenna to operate in multiple frequency bands. A novel compact fractal antenna based on self-similar stair-shaped fractal geometry is proposed in this paper. The fractal antenna is designed by modifying the patch antenna through the iterative process using stair-shaped fractal geometry. The third iteration results in a tri-band response, and the antenna resonate at 3.65, 4.825, and 6.325 GHz with impedance bandwidths of 75.6, 121.2, and 211.4 MHz, respectively. The antenna is designed in CST Microwave studio, and evaluated for operating bands and radiation characteristics. Prototype for the third iteration of the fractal antenna is fabricated on FR-4 substrate which is further tested for measured operating bands and radiation characteristics. The simulated and measured results show good agreement.

Authors: Wadi Mohammed 
Published: November 2021

Abstract
With the increased complexity of power systems and the high integration of smart meters, advanced sensors, and high-level communication infrastructures within the modern power grids, the collected data becomes enormous and requires fast computation and outstanding analyzing methods under normal conditions. However, under abnormal conditions such as faults, the challenges dramatically increase. Such faults require timely and accurate fault detection, identification, and location approaches for guaranteeing their desired performance. This paper proposes two machine learning approaches based on the binary classification to improve the process of fault detection in smart grids. Besides, it presents four machine learning models trained and tested on real and modern fault detection data set designed by the Technical University of Ostrava. Many evaluation measures are applied to test and compare these approaches and models. Moreover, receiver operating characteristic curves are utilized to prove the applicability and validity of the proposed approaches. Finally, the proposed models are compared to previous studies to confirm their superiority.

Published: November 2021

AbstractA wideband down conversion ring mixer is proposed for multi band orthogonal frequency division multiplexing (MB-OFDM) system in 180 nm CMOS technology. The mixer is essentially used in a heterodyne wireless receiver to enhance the selectivity of the system. Being a nonlinear system, the mixer dominates the overall performance of the system. The design of down conversion mixer is the most challenging part of a receive chain. Wideband impedance matching always remains a challenge in any radio frequency integrated circuit design. This paper presents the design of a ring mixer with high linearity, wideband impedance matching using differential resistive impedance matching and without using any DC bias. The proposed mixer is tuned for a frequency of 3.432 GHz of band 1 of the MB-OFDM system. Mixer core is based on the FET ring mixer topology. The mixer is implemented in 180 nm CMOS technology. The mixer achieves the minimum conversion loss of 10.49 dB, 1 dB compression point (P1) of 12.40 dBm, third order input intercept point (IIP3) of 12.01 dBm, a minimum SSB noise figure of 8.99 dB, andS11of less than -10 dB over the frequency range of 0 to 13.61 GHz . The layout of the mixer records an active area of 183.75μm2.
