Dispersion of watermelon rinds as secondary raw materials in technologies of pectin-containing extracts and film structures

The development of protective coatings based on pectin substances that serve as natural structure-forming agents developed from a secondary resource base is focused on removing a complex problem in the production of finished products by deep processing of basic raw materials and developing an original film material. At the same time, the technical result of obtaining pectin-containing film structures is their ability to protect food products from microbiological spoilage, natural losses during storage and the preservation of quality and safety indicators. An important preparatory procedure that determines the efficiency and intensity of extraction processes can be attributed to the operation of dispersing the feedstock, since it directly affects the size of the contact surface area of the phases involved in mass transfer. However, it is clear that the greater the degree of grinding, the higher the efficiency of the process, but an excessive increase can lead to additional unjustified energy costs and, as a result, to an increase in the cost of the finished products sold. In this regard, the purpose of the research is to analyze existing technologies for producing pectin-containing extracts, in which watermelon rinds can be used as secondary resources and to intensify the extraction process by conducting a rational preparatory procedure for grinding the raw materials. The object of the research are watermelon rinds as non-recyclable waste from processing watermelon raw materials. According to the obtained graphs, and taking into account the high rates of gelatinization of the obtained pectin extracts, it is possible to recommend a complex treatment of watermelon rinds, including, in addition to the operations of preliminary preparation of raw materials, ultrasonic exposure and acid hydrolysis, and it is desirable to use food acids, for example, acetic or citric, instead of aggressive sulfuric and hydrochloric acids. As a result of the study of the dispersed composition, it has been concluded that the average equivalent particle size of the dispersed raw materials does not exceed the recommended limits, that is, the result obtained can be considered acceptable.

Queer Theory and Nontheatrical Films: Perversion in the Public Domain

This chapter considers the intersection of queer theory and nontheatrical film studies by examining antipornography film Perversion for Profit (1962). Produced and distributed by Citizens for Decent Literature, the film visualizes a range of straight and gay pornographic images by censoring and categorizing them as evidence of societal aberrations. Now in the public domain and streaming on Internet Archive, the film’s pornographic images have been repurposed for new meanings. By analyzing Barbara Hammer’s inclusion of Perversion in her experimental film History Lessons (2000) and a mash-up of the original film titled Come Join the Fun! (2004), shared on Internet Archive, the chapter argues that the Perversion’s value now lies in what queer creators make of its cinematic time and space.

Sound as Signifier: Communication and Expression Through the Sound of Clothing

Fashion, clothing, and dress have traditionally been evaluated on visual characteristics. This paper focuses on the aural qualities of clothing and on what is being communicated through sound. Semiotic theory, in particular denotation and connotation, discusses the ability of clothing to communicate through sound. Philosophical ideas of expression through music and sound emphasized the significance of feeling and experience in art and fashion. Five garments were designed as sound objects to explore this link between sound and clothing. The garments are featured in a video in which two musicians dance in the pieces. Musician Born Gold created an original film score from the recorded sounds of the pieces. These works attempted to direct the focus of fashion experience towards sound, without disregarding the cultural emphasis on visual aesthetics. The intention is to shift the way individuals relate to their clothing, to a fuller and more cognizant sensory experience.

Notions of Place, Legend, and Broadway in Monty Python’s Spamalot

This chapter shifts to the Broadway musical Monty Python’s Spamalot (2005). As an adaptation of Monty Python and the Holy Grail, Spamalot adds numerous songs written by Eric Idle and John du Prez. These songs not only send up Arthurian legend but common musical theater tropes, augmenting the “meta” tone of the show for fans of musical theater history as well as Monty Python. Furthermore, the musical incarnation increases many of the roles from the original film and includes new characters, extending the connections to the world of Arthurian legend. The musical’s expanded pantheon of references and musical theater send-ups highlight the interpretive layering in a meaningful way. The author’s analysis triangulates the legend with Holy Grail and Spamalot, arguing that while Monty Python may play fast and loose with ideas of fidelity, their versions of Arthurian legend remain true to the malleable spirit of the tale.

Improved Breakdown Strength of Polypropylene Film by Polycyclic Compounds Addition for Power Capacitors

In this paper, an improved method for the electric performance of polypropylene (PP) film was proposed to promote the safety and stability of power capacitors. Modified PP films containing three different polycyclic compounds were prepared, which showed good thermal properties and decreased DC conductivity. The DC breakdown strength of the modified PP films under both positive and negative voltage is increased compared with that of the original film. The deep traps introduced by polycyclic compounds and the decreased carrier mobility give an explanation of the decreased DC conductivity. A quantum chemistry calculation was further performed to clarify the mechanism for improving electrical performance, presenting that polycyclic compounds with a high electron affinity and low ionization energy can capture high-energy electrons, protecting the PP molecular chain from attack, and then increase the breakdown strength. It is concluded that the modified PP films by polycyclic compounds have great potential in improving the insulating properties of power capacitors.

Forty years later: Laurie Strode and the survival of the Final Girl

The Final Girl trope is well established in horror, and the Final Girl’s actions leading up to and including the moment of her ‘triumph’ over the monstrous threat have generated a rich vein of scholarly and popular discourse. However, the life and experiences of the Final Girl beyond the violent events that initially defined her have largely remained unexplored despite the repetitive appearance of characters like Laurie Strode across horror franchises. By pairing John Carpenter’s 1978 Halloween and David Gordon Green’s 2018 Halloween – positioned as a direct sequel to the original film – the life of the Final Girl beyond her confrontation with the monstrous threat is made visible, and the experiences and effects of trauma are centred. An analysis of the visual and narrative manifestations of Laurie Strode’s experience of trauma makes clear the limits of the traditionally constructed trope by asking what it means to survive within horror franchises. Acknowledging the Final Girl as a survivor of trauma fosters new possibilities for how the Final Girl trope is discussed and calls attention to the ways that representations of trauma within the horror genre can reflect and reify the experiences of survivors in positive and productive ways.

Optimization and Analysis of Plastic Film Consumption for Wrapping Round Baled Silage Using Combined 3D Method Considering Effects of Bale Dimensions

HighlightsSolved the problem of optimal design, in the sense of minimal film usage, of round bale diameter and height.Necessary and sufficient optimality conditions derived in the form of easy-to-solve cubic equations.Bales of a maximum volume achievable with an actual wrapper and of optimal dimensions ensure minimal film usage.Up to 10% savings in film usage if bale dimensions are optimally designed and wrapping parameters properly selected.Abstract. The combined 3D method is used for wrapping cylindrical bales of agricultural materials based on biaxial rotation of the film applicators. The demand for minimization of plastic film consumption keeps increasing, with the goal to save the environment, reduce plastic costs, and minimize wrapping time. Consequently, methods have been reported to solve the problem of optimal wrapping parameters for the conventional wrapping method. In this article, a model-based problem of such a design based on round bale dimensions (diameter and height) that minimizes film consumption for the combined 3D method is mathematically formulated and analyzed. The film consumption per unit of bale volume is used as a measure of film usage. Generally, it is difficult to find the optimal bale dimensions that minimize the original film usage index, due to the discontinuity of the index. Thus, near-optimal parameters, being as important as optimal parameters for engineering applications, are looked for. The problem of selecting near-optimal bale dimensions was constructed by minimizing the continuous lower bound of the original film usage index. The necessary and sufficient optimality conditions for near-optimal bale dimensions were established in the form of standard cubic equations, which can easily be solved using both analytical and numerical methods. Based on the optimality conditions, analytical and numerical analyses were performed of the influence of film width, pre-assumed bale volume, and numbers of bottom and upper film layers on the near-optimal bale dimensions and film usage. The results indicated that the near-optimal bale diameter and height, hereinafter called optimal, monotonically increase, while the optimal film consumption monotonically decreases, with increasing pre-assumed bale volume. Therefore, it is recommended to use bales of a maximum volume achievable with an actual wrapper and of optimal dimensions, i.e., diameter and height. The film width also influences the optimal bale dimensions and film usage: the wider the film, the smaller the minimal film usage. To confirm the effect of near-optimal bale design on film usage, the errors of the near-optimality were examined for four to sixteen film layers. The results of the numerical experiments demonstrated that for four to sixteen layers of film, there are compositions of the bottom and upper film layers for which the relative near-optimality errors do not exceed 0.01% whenever the optimal bale dimensions are used. Simultaneously, inappropriate selection of wrapping parameters may result in increased film usage, measured by mean relative errors of 1% to 9.5%, which means up to 10% film cost savings when the bale dimensions are optimally designed according to the proposed approach, and the wrapping parameters are appropriately selected.

Speech Act (Im)Politeness and Audiovisual Constraints in Translation for Dubbing

The present article sets out to explore the under-researched relationship between linguistic (im)politeness and audiovisual translation, by taking the speech act of requests as object of analysis in English films and in their dubbed Italian versions. As dubbing constraints often lead translators to depart substantially from the original utterance, the study shows how linguistic changes can result in alterations of the (im)polite load inherent in the requests from original film versions. The study focuses on pragmatic strategies for realizing requests in English film dialogues and shows that dubbing constraints may underlie the adoption of different pragmatic strategies for the requests of target-language dialogues. The (im)politeness shifts that this linguistic modification process entails may make the same character come across as more or less (im)polite in the target-language version and are, for this reason, worth investigating.
