Digitized technology and evolving selfie obsession among University of Port Harcourt students: A gendered culture?
Authors: God’spresence Emily Oghale , God’spresence Azuka F.N.
Published: May 2021

Digitization is a prime globalized ideology in the 21st century high tech revolution. It essentially deals with automation of manual process to make room for easy documentation and sustainable data regime. Africa is an emerging digital domain with many of its young generation becoming keen lovers of Information Technology (IT), and many of the youth population fast becoming internet devotees, social and new media addicts. One of the trending fantasies, among the numerous exploitations and innovations of the new technology is selfie. Selfie is simply a selfphotograph of a person’s portrait by himself. This is possible by the use of smartphone or digital camera held out at arm’s length by the person taking the snapshot. Presently, there is craze for digital identity among African youths. It is against this background that undergraduate students at the University of Port Harcourt were sampled purposively for deployment in this study. This study utilizes questionnaire and Focus Group Discussion (FGD) as instruments for data gathering in order to determine whether the use of selfies is more common to the male or female members of the African digital society. Finally, the study is guided by Uses and Gratification theory and Symbolic Interactionism Theory.
Directing gender equality in Ahmed Yerima’s Altine’s Wrath
Authors: Edum Sunday
Published: May 2021

One of the functions of the theatre director is to develop a concept that would appeal to the audience in the process of his interpretation. This paper textually evaluates the issue of gender equality as the directorial concept in Ahmed Yerima’s Altine’s Wrath. The paper adopts the sociological, literary and artistic methods to interrogate the directorial implications of the text as it will be demonstrated in the performance. The paper notes that a thorough understanding of gender theories and principles would guide a director’s realization of the identified concept. The paper, therefore, calls on directors to support the issue of gender equality by developing concepts in this regard and as such promote a peaceful society.

Published: May 2021

Coexistence of different histopathological types of basal cell carcinomas (BCC) in the same anatomical localisation is rare, and, therefore, is engaging for histopathologists and clinicians. In many cases, the determination of a neoplasm type remains difficult, since BCC may consist of more than one histopathological subtype. Mixed BCCs often present with an aggressive course and recurrence when compared to other subtypes of a tumour. Furthermore, tumours of this type are associated with time-consuming treatment and not a very satisfactory cosmetic result, thus worsening the quality of the patient’s life. Several clinical studies have been published regarding the histopathologically diverse tumours developed in the same anatomical region; however, largely peculiarities of mixed BCCs are not explored sufficiently. The purpose of this study was to substantiate the use of dermoscopy and morphology, assessing mixed type BCC of the head and neck. The tumours were removed with a surgical excision of 1 cm margins, and the tumour sites were assessed in a 24-month-long follow-up period. The dermoscopic characteristics of mixed and aggressive BCC are analysed in this study. Finally, to better estimate the invading cone of the tumour, a complex morphology, which included collagen type IV and podoplanin immunohistochemistry, and electron microscopy were used.

Our study was focused on identification and correction of early hyperglycaemia, with the aim to reduce the risk of developing post-transplant diabetes mellitus (PTDM) and its associated complications. In a single centre, the prospective study included adult kidney transplant recipients without diabetes mellitus whose pre-transplant glucometabolic data did not show signs of diabetes mellitus. Starting from the first day after kidney transplantation, patients were closely monitored for hyperglycaemia; glucose level measurements were started to obtain pre-prandial levels. If the blood glucose level exceeded 11.1 mmol/l, hyperglycaemia was corrected with short-acting insulin. A total of 14 patients completed a three-month follow-up. During the first post-transplant week, the blood glucose level exceeded 11.1 mmol/l in nine patients (63.9%). From those patients five (55.5%) did not develop PTDM. None of the patients who did not need insulin treatment developed PTDM. Higher pre-lunch glucose levels increased the risk of developing PTDM (p = 0.006). Patients with diabetes required a two times higher insulin dosage than other patients during the first post-transplantation week. We found that hyperglycaemia is a common problem in the early post-transplant period. Early recognition and correction of inpatient hyperglycaemia was associated with reduction of the prevalence of PTDM in more than a half of the patients in the studied group at three months post transplant.
Behandeln, Aufarbeiten und Reparieren durch Kunst: zeitgenössische Darstellungen der vom Krieg „verletzten“ Landschaften Ost-Frankreichs
Authors: Müller Susanne
Published: May 2021

Der erste Teil des Beitrags ist theoretischen Aspekten des Behandelns, Aufarbeitens und Reparierens durch Kunst gewidmet. Das deutsche Verb „behandeln“ beleuchtet hierbei am deutlichsten die Vielschichtigkeit eines künstlerischen Ansatzes, der Kreation und Rezeption stets zusammendenkt, ohne die materielle bzw. „handwerkliche“ (be-hand-eln) Dimension von Kunstwerken zu missachten. Das im französischen Kontext gebrauchte Verb „reparieren“ (réparer) unterstreicht hingegen die paradoxe Wiedergutmachung, die Kunst möglich macht, ohne die Spuren (Narben) des Zerbrochenen/Verletzten seiner Inhalte zu beseitigen. Die „Aufarbeitung“ hebt schließlich hervor, dass es sich um ein Hervorholen vergangener Sujets handelt, die indes im Hier und Jetzt physische und psychische Spuren hinterlassen haben. Die vom Krieg und diversen Grenzverschiebungen gezeichneten Landschaften Ost-Frankreichs stehen im Fokus des zweiten Teils, der anhand ausgewählter zeitgenössischer Kunstwerke – insbesondere aus dem Bereich der künstlerischen Fotografie – das besondere Potenzial der Kunst im Kontext des Gedenkens des Ersten Weltkriegs hervorhebt.
Polityczne gry w patos jako sposób zawłaszczania społecznej wyobraźni
Authors: Łukomski Piotr
Published: May 2021

The paper presents a model of the analysis of politics from the perspective of aesthetic values based on the basic assumptions of game theory. The model includes three values: pathos, sublime and comism. The analyzed values are considered as features of cultural images of political games appearing in different contexts of political actions. Three types of contexts referred to by politicians have been distinguished: archaic, revolutionary and modern eschatological contexts.
Od kultury popularnej do geopolityki popularnej
Authors: Macała Jarosław
Published: May 2021

A large portion of geopolitical research of the last decades, especially geopolitical criticism, undertakes the concept of the importance of culture, value and identity in explaining the relation between the space and politics, which was an aspect underappreciated by classical and neoclassical geopolitics. It might be assumed that the currently growing role of popculture and mass-media in our lives lead to the establishment of a kind of a “cultural order”, a particular filter that decides on the perception of the world and, consequently, geopolitics. This article relates to this issue as it deals with the meaning of popular culture in contemporary geopolitical research, mostly accentuated by popular geopolitics. This review briefly analyses what popular geopolitics is, how to sketch its research area, stages of development, applied definitions and research methods. The starting point is the assumption that the hegemonic structure of geographical/geopolitical thinking that the elites are trying to impose on the society by using popcultural artifacts may, in fact, be reconstructed thanks to popular geopolitics studies. It shows the scale and reach of resistance towards such imaginations as displayed by the non-elites, who also reach for symbols, texts and images from popular culture. Such circumstances allow to observe either legitimizing or debunking a particular view of the world and geopolitics.
Europejskie sieci współpracy kulturalnej: zmiana paradygmatu politycznego?
Authors: Gierat-Bieroń Bożena
Published: May 2021

The article attempts to answer the question on the role of social and cultural networks of international cooperation in contemporary Europe. The processes of European integration facilitated the creation of networking relations between cultural organs in various member states. The four freedoms of a single market (the free movement of people, goods, services and capital) supported the internationalization and Europeization of public sectors, shaped the cultural exchange and built a European civil society. At least since the 1970s, the European Economic Community/European Union led the policy of encouraging cultural operators to network and assigned European funds to support this goal. At this moment, we deal with nurtured and lasting forms of international cooperation between public entities in Europe. The civil society is also gaining more power. Because of the noticed re-nationalization or the trendy concept of returning to the “Europe of homelands” and countries closing themselves because of economic and political particularities, several research questions are bound to arise. The most crucial one regards the depletion of the apolitical paradigm of civil activities and its possible – unintentional yet inescapable – politicization of the so-called third sector.
Theodore’a Roszaka wizja pięknej polityki
Authors: Góra Dariusz
Published: May 2021

Theodore Roszak is one of the best known researchers of countercultural movements of the 1960s. This article assumes that the researcher, not being a doctriner or trendsetter, tried to organize and describe the chaos of the existing reality in a scientific way so as to prove, in a second step, the thesis that the vision he depicts is a political program worth promoting. None of the American author’s books have been translated into Polish. This article would like to bring the ideas of the most important Roszak’s work published in 1969. The leitmotiv of the article is Roszak’s vision of “beautiful politics”. By means of the comparative method, the content of the author’s most important work is compared with other statements, including especially his latest publication from 2009. The use of the comparative method in the biographical aspect leads to surprising conclusions in relation to the previously developed argument.
Nekropolityka: Polityczny wymiar pogrzebów polskich pisarzy na przykładzie sprowadzenia do Polski prochów Juliusza Słowackiego w 1927 roku oraz Stanisława Ignacego Witkiewicza w 1988 roku
Authors: Mrowiński Paweł Marek
Published: May 2021

The article is devoted to comparative analysis of two repatriations: bringing ashes of Juliusz Słowacki in 1927 and bringing remains of Stanisław Ignacy Witkiewicz in 1988. Both these events, being socio-political performances, fit into the broader concept of necropolitics, in which they are analyzed. The article compares the causes of the political nature of these ceremonies, their conduct, public reception and the effectiveness of counteracting the socio-political crisis, which was one of the main reasons for reaching for the funeral ritual by the rulers. The main purpose of the article, in addition to the comparative analysis of the above elements, is to emphasize the political dimension of mourning ceremonies, which can successfully be the subject of research in political science.
Mrzonki o pokoju. Wojna nemezis ludzkości
Authors: Otto Justyna Grażyna
Published: May 2021

The main thesis of the article is as follows: war shares a lasting and unbreakable bond with human life and state politics and, despite the Utopian dreams of never-ending peace, conflicts are the sine qua non building blocks of a country’s policy and the development of the human race. Why? Because a state is an imperfect, yet the most perfect among the civilisationally achievable means of organising the lives of people who, for various reasons, display war inclinations. This paper is a political sciences analysis of the problem from the perspective of history of political philosophy. To achieve the research goal, the author first analyses the Utopian visions of peace ruling over war and the designs of eternal peace, putting forward subtheses on the primate of peace over war and the human drive towards peace which was to be determined by 1). religion, 2). proper upbringing and education as well as the new organisation of a society and its reflection in the federalist project. These theses are debunked and proven to be wishful thinking as each human being and each state have violence in their genetic code.

Authors: Huy Nghiem Xuan , Hoai Tran Thi , Nhat Ngo Tien , Anh Nguyen Thi Tuyet , Duy Dang Van , Ha Nguyen Thi Thu
Published: May 2021

The paper analyzes a number of factors related to scientific research activities including support policies; facilities, equipment and materials for scientific research; support from the universities to students in the development of four CDIO competencies (Conceive - Design - Implement - Operate). The authors then evaluate the impact of the above factors on the student's competency development in the CDIO training model. The authors surveyed 1401 academic staff, 2306 students and conducted semi - structured interviews of 18 lecturers at 6 Vietnamese universities. The results show, from the most to the least influential groups of factors in the student competency development: facilities and equipment for practice, internship and scientific research activities, the university's support in the 4 CDIO phases and the policy matters, respectively. In general, all four students' competencies are assessed at a fairly high level and vary among universities. Specifically, the ability to form ideas was the highest rated, followed by the ability to design products, and the lowest rated competencies are to test and operate products in practice. Based on the findings, the authors proposed 6 solutions to improve student’s competencies in the CDIO training model.

Published: May 2021

The biomimetic total synthesis of (+)-chloropupukeananin (overall 4.5% yield, 19 steps from pyrone 22) and (−)-chloropupukeanolide D via an intermolecular Diels-Alder reaction using (−)-maldoxin and (+)-iso-A82775C and an intramolecular carbonyl-ene reaction has been achieved. Moreover, the biomimetic synthesis of chloropestolides H-K using (−)-maldoxin and siccayne unveiled the solvent effect of the intermolecular Diels-Alder reaction. The origin of the stereoselectivity of the intermolecular Diels-Alder reaction is still elusive; however, the biosynthesis of the chloropupukeananin family should involve enzymes that catalyse the intermolecular Diels-Alder reaction.
Breaking C–C Bonds via Electrochemically Mediated Hydrogen Atom Transfer Reactions
Authors: Yan Bing , Shi Changxia , Beckham Gregg T. , Chen Eugene Y.-X. , Román-Leshkov Yuriy
Published: May 2021

Cleaving inert sp3-sp3 carbon-carbon (C-C) bonds selectively remains a major challenge in organic chemistry and a main bottleneck in the chemical upcycling of recalcitrant polyolefin waste. Here, we present an electrochemical strategy using redox mediators to activate and break C-C bonds at room temperature and ambient pressure. Specifically, we use N-hydroxyphthalimide (NHPI) as a redox mediator that undergoes electrochemical oxidation to form the phthalimide-N-oxyl (PINO) radical to initiate hydrogen atom transfer (HAT) reactions with benzylic C-H bonds. The resulting benzylic carbon radical is readily captured by molecular oxygen to form a peroxy radical that decomposes into oxygenated C-C bond-scission fragments. This indirect, mediated approach for Csp3-Csp3 bond cleavage reduces the oxidation potential by > 1.2 V compared to the direct oxidation of the substrate, thereby eliminating deleterious side reactions, such as solvent oxidation, that may occur at high potentials. Studies with a bibenzyl model compound revealed a bifurcated reaction pathway following the initial HAT step. At a bibenzyl conversion of 61.0%, the C-C bond cleavage pathway generates benzaldehyde and benzoic acid products at 38.4% selectivity, and the C-H bond oxygenation pathway leads to 1,2-diphenylethanone and benzil products at 39.2% selectivity. Changes in reaction selectivity were investigated with various model compounds, including bibenzyl, 1,3-diphenylpropane, 1,4-diphenylbutane, and their derivatives. Product selectivity is correlated with the C-C bond strength of the reactant, with weaker C-C bonds favoring the C-C bond cleavage pathway. We also evaluated the mediated oxidation of oligomeric styrene (Mn = 510 Da, OS510) which were converted into oxygenated products. Lastly, proof-of-concept depolymerization of polystyrene (PS, ~10,000 Da) into oxygenated monomers, dimers, and oligomers was demonstrated using NHPI-mediated oxidation.
Late-Stage β-C(sp3)–H Deuteration of Carboxylic Acids
Authors: Uttry Alexander , Mal Sourjya , van Gemmeren Manuel
Published: May 2021

Carboxylic acid moieties are highly abundant in bioactive molecules. In this study we describe the late-stage β-C(sp3)–H deuteration of free carboxylic acids. Based on our finding that the C–H activation with our catalyst systems is reversible, the de-deuteration process was first optimized. The resulting conditions involve ethylenediamine-based ligands, which, amongst other positions, for the first time enables the functionalization of non-activated methylene β-C(sp3)–H bonds and can be used to achieve the desired deuteration when using a deuterated solvent. The reported method allows for the functionalization of a wide range of free carboxylic acids with diverse substitution patterns, as well as the late-stage deuteration of bioactive molecules and related frameworks.
Acoustofluidic Medium Exchange for Preparation of Electrocompetent Bacteria Using Channel Wall Trapping
Authors: Gerlt Michael , Ruppen Peter , Leuthner Moritz , Panke Sven , Dual Jürg
Published: May 2021

Transformation, i.e. reprogramming of bacteria by delivering exogenous genetic material (such as DNA) into the cytoplasm, is a key process in molecular engineering and modern biotechnology in general. Transformation is often performed by electroporation, i.e. creating pores in the membrane using electric shocks in a low conductivity environment. However, cell preparation for electroporation can be cumbersome as it requires the exchange of growth medium (high-conductivity) for low-conductivity medium, typically performed via multiple time-intensive centrifugation steps. To simplify and miniaturize this step, we developed an acoustofluidic device capable of trapping the bacterium Escherichia coli non-invasively for subsequent exchange of medium, which is challenging in acoustofludic devices due to detrimental acoustic streaming effects.

With an improved etching process, we were able to produce a thin wall between two microfluidic channels, which, upon excitation, can generate streaming fields that complement the acoustic radiation force and therefore can be utilized for trapping of bacteria. Our novel design robustly traps Escherichia coli at a flow rate of 10 µL minute-1 and has a cell recovery performance of 47 ± 3 % after washing the trapped cells.

To verify that the performance of the medium exchange device is sufficient, we tested the electrocompetence of the recovered cells in a standard transformation procedure and found a transformation efficiency of 8∙105 CFU per µg of plasmid DNA. Our device is a viable low-volume alternative to centrifugation-based methods and opens the door for miniaturization of a plethora of microbiological and molecular engineering protocols.

Published: May 2021

The aim of the present study was to evaluate the protective effect of methanol garlic extract on the enzymes related with polyol pathway, advanced glycation end products, markers of oxidative stress and antioxidant status in brain of streptozotocin induced diabetic rats. Antioxidant capability of methanol extract of garlic was evaluated by 2,2-diphenyl-2-picrylhydrazyl hydrate radical and FOX (ferrous ion oxidation-xylenol orange) H2O2 scavenging test. Diabetes was induced by single i.p injection of STZ (32mg/kg per body Wt.,). Blood glucose levels and body wt, were measured on every 7th day over a period of 30 days. The diabetic rats treated with garlic extract at two doses 250mg/kg and 500mg/kg body wt., by oral administration. Diabetic rats showed significant increase in food and water intake, decrease in blood glucose levels, body weights, but could not show any recovery by garlic treatment. Garlic treatment significantly decreased aldose reductase (AR); sorbitol dehydrogenase (SD) and glutathione S-transferase (GST) enzyme activities. A decrease of malndialdehyde (MDA), Protein carbonyls (PC), Pentosidine advance oxidation protein products (AOPP), Advanced glycation end products (AGEs) was also observed. Additionally garlic administration produced a restoration of brain superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and reduced glutathione (GSH) in diabetic rats. Garlic treatment also reduced the free radical formation and progression of hyperglycemia induced diabetic complications by decreasing influx of glucose into the polyol pathway and increased activity of antioxidant enzymes. The current study reveals exerts, efficiently, an attenuating effect of methanol garlic extract exterted antihyperlgycemic, antioxidant and anti-glycating effects in a dose dependent manner in diabetic rats.
Infodemics and infodemiology: a short history, a long future
Authors: Zielinski Chris
Published: May 2021

An “infodemic” is defined as “an overabundance of information – some accurate and some not – occurring during an epidemic”. This paper describes the characteristics of an infodemic, which combines an inordinately high volume of information (leading to problems relating to locating the information, storage capacity, ensuring quality, visibility and validity) and rapid output (making it hard to assess its value, manage the gatekeeping process, apply results, track its history, and leading to a waste of effort). This is bound up with the collateral growth of misinformation, disinformation and malinformation. Solutions to the problems posed by an infodemic will be sought in improved technology and changed social and regulatory frameworks. One solution could be a new trusted top-level domain for health information. The World Health Organization has so far made two unsuccessful attempts to create such a domain, but it is suggested this could be attempted again, in the light of the COVID-19 infodemic experience. The vital role of reliable information in public health should also be explicitly recognized in the Sustainable Development Goals, with explicit targets. All countries should develop knowledge preparedness plans for future emergencies.

Published: May 2021

Objetivo. Informar sobre la oposición a las vacunas y la información errónea fomentadas en Twitter, destacando las cuentas de Twitter que dirigen estas conversaciones.

Métodos. Utilizamos el aprendizaje automático supervisado para codificar todos los mensajes publicados en Twitter. En primer lugar, identificamos manualmente los códigos y los temas mediante un enfoque teórico fundamentado y, a continuación, los aplicamos a todo el conjunto de datos de forma algorítmica. Identificamos a los 50 autores más importantes un mes tras otro para determinar las fuentes influyentes de información relacionadas con la oposición a las vacunas.

Resultados. El período de recopilación de datos fue del 1 de junio al 1 de diciembre del 2019, lo que dio lugar a 356 594 mensajes opuestos a las vacunas. Un total de 129 autores de Twitter reunieron los criterios de autor principal durante al menos un mes. Los autores principales fueron responsables del 59,5% de los mensajes opuestos a las vacunas y detectamos diez temas de conversación. Los temas se distribuyeron de forma similar entre los autores principales y todos los demás autores que declararon su oposición a las vacunas. Los autores principales parecían estar muy coordinados en su promoción de la información errónea sobre cada tema.

Conclusiones. La salud pública se ha esforzado por responder a la información errónea sobre las vacunas. Los resultados indican que las fuentes de información errónea sobre las vacunas no son tan heterogéneas ni están tan distribuidas como podría parecer a primera vista, dado el volumen de mensajes. Existen fuentes identificables de información errónea, lo que puede ayudar a contrarrestar los mensajes y a fortalecer la vigilancia de la salud pública.
Doing it for the ‘Gram: How Instagram affects values, and what it means for mental and ecological wellbeing
Authors:   , Vautier Melanie
Published: May 2021

What would it mean to cultivate a culture of thriving people on a thriving planet? Research has shown that intrinsic values are a significant predictor of both environmentally responsible behaviour and mental wellbeing. However, in modern Western culture, extrinsic, self-promotional values continue to grow in prominence. In order to examine how a specific social context may be exacerbating extrinsic values, counter to mental and ecological wellbeing, this study looks at the social media platform Instagram. Through in-depth interviews of young adults in Aotearoa New Zealand, this study examines their experiences of Instagram in order to ascertain if and how it may promote extrinsic values. Results were analysed through Self Determination Theory, which states that environments which thwart basic human needs of relatedness, competence and autonomy will incentivise extrinsic values. While in some cases, Instagram increased access to relatedness, participants also experienced thwarted relatedness when interactions became motivated predominantly by posting them, and thus self-promoting, on the platform. Participants also consistently reported feeling incompetent when comparing themselves to others' images, which, particularly when adjacent to advertising, as in the case of Instagram, is likely to lead to materialistic tendencies. Participants were also aware of, and in some cases responded to, Instagram signals as to what type of content would gain more 'likes,' adjusting their behaviour in order to succeed in a 'marketplace' infrastructure, thereby limiting autonomy. In doing so, intrinsically motivated experiences were overtaken by an extrinsic desire to portray them to others. These examples indicate Instagram’s infrastructural incentives toward extrinsic values, which counter societal goals of mental and ecological wellbeing. Pervasive messaging within social contexts such as Instagram needs to shift away from promoting extrinsic values in order to respond adequately to the current ecological challenges and create conditions conducive to mental wellbeing.

Published: May 2021

Purpose: Many developing countries are espousing export promotion strategies for accelerating growth. All the firms in a country are not exporting due to various factors and characteristics. One of the factors is finance or balance sheet that affects the investment decisions and export tendencies and intensities of the firms. This study aims to explain the link between financial health and exports sales.

Design/Methodology/Approach: We have applied the fixed-effect model and Granger Causality test to find the results.  We have taken the data of 190 firms related to the manufacturing sector of Pakistan from 2005 to 2016.

Findings: We have taken four financial ratios to measure the financial health of the manufacturing sector of Pakistan. Debt to equity ratio and financial leverage ratio has shown negative sign with the exports sales while coverage ratio and liquidity ratio have appeared with a positive sign with exports sales. Moreover, the effect of total assets, concentration ratio, capital-output ratio and exchange rate have also been probed.

Implications/Originality/Value: The study suggests that the financial health of the firm is an important factor in determining export sales so the financial health of the firm should be good and sound so that export sales may be enhanced

The article presents the results of studies in meat productivity of the Aberdeen Angus bull calves, depending on the constitution type. In each group, 14 bull calves were selected from the offspring of 4 large and 3 small bulls of the Aberdeen Angus breed. The first group consisted of bull calves from large and tall type of servicing bulls. The second group consisted of bull calves from small type of servicing bulls. They were put under control growing right after weaning. It was found that the bull calves from the large type of servicing bulls were superior to the bull calves from the small type of servicing bulls in terms of meat productivity, which was primarily shown in a higher growth rate. At the age of 18 months, bull calves from large-type parents reached 442 kg of their mass. Bull calves from small-type parents reached 413 kg. The bull calves from the first group had a greater pre-slaughter weight by 31.4 kg and heavier carcasses compared to the bull calves from the second group by 28.3 kg or 13.5 % (P>0.99). In terms of slaughter weight, they were superior to their herdmates from the second group by 26.5 kg. The carcasses of tall bull calves from the first group had larger content of bones (by 4.08 kg) compared to the second group. In their carcasses, 4.52 kg of meat account for 1 kg of bones, while in the carcasses of the second group – 5.03 kg. However, in general, when deboning the half carcasses of the first group, 9.9 kg. or 11.72% more meat was obtained (Р>0.99) compared to the second group.

At the same time, the developed technological scheme and the principle of operation of the experimental machine are presented. The experimental machine is based on the SZS-2,1 seeder with a reel-to-reel sowing device. The experimental seeder is additionally equipped with Romanian-made "HRC" seed drills.Processing the results of experiments of mathematical statistics show that with an increase in the speed of the tractor movement, the coefficient of variation, the arithmetic mean and root-mean-square value increases.
Application of artificial neural networks for irrigation control
Authors: Kamyshova Galina Nickolaevna
Published: May 2021

Modern methods of precision farming, based on the requirements of the spatio-temporal optimality of irrigation of agricultural crops, require new approaches, since achieving the required accuracy is impossible without the use of modern digital technologies and intelligent methods. The article presents a model of operational irrigation management based on an artificial neural network. The advantage is the small error of the neural network algorithm and its ability to adapt to changing conditions, in contrast to traditional methods, which makes it possible to provide optimal results for different types of soils and types of crops.

Three-channel PID controllers are widely used in industrial control systems. It is noted that the popularity of PID controllers in the control of industrial processes is explained by their ability to ensure high quality of processes in a wide range of modes, as well as functional simplicity that allows engineers to operate them without any problems.
The impact of student timetables and commuting on student satisfaction

Widening participation has encouraged students from a diverse range of backgrounds into university with more students commuting (many being Black and Minority Ethnic, BME). Since timetabling forms a major way by which students identify and interact with their learning environment understanding its influence is important. This project aimed to identify the experiences of students with their timetables using questionnaires and focus groups to determine perceptions and relationship to travel to university by ethnicity, gender, age and level of study. Five hundred and fifty students participated across levels 4 to 6 at Kingston University. There was a strong negative correlation between travel time and ‘the timetable works efficiently for me’ (Question 16, National Student Survey). Students from ethnic backgrounds on average were found to travel double the distances of their White counterparts to get to university. In addition, timetable satisfaction was also reflected in the modes of transport used and in perceptions of expected timetabled hours (i.e., whether too many or too few hours scheduled) based on travel times. We identified a number of inclusive priorities to help improve the timetable for student groups including having later starts to days and one guaranteed day free per week. In addition, the COVID-19 world has temporarily reduced the need for most students to commute and can be regarded as a positive disruptor for future commuting students. Certainly, it will be important to find a new balance in applying the identified priorities and the realised alternative COVID-19 teaching practices for creating more inclusive, flexible and blended learning environments to achieve the ultimate student-centred timetable.

The aim of this research is to reveal the effects of brochures and virtual reality, which are among the promotional tools in destination marketing, on the purchasing intention and compare the results of these two promotional tools. The theoretical background of the research was established within the framework of the Theory of Planned Behavior (TPB). 120 potential tourists living in Eskişehir who intend to go on holiday, have been reached during the implementation phase of the research. Two questionnaires, i.e. the brochure involvement and virtual reality involvement questionnaires, were obtained from the participants. The data were analyzed through Smart PLS v.3.2.7. Research findings demonstrate that virtual reality is more successful in the perceived service quality and product attitude development. However, the effect of the brochure on the development of advertising attitudes is higher. Some suggestions are presented in line with the results of the research.

A study was carried out at the research farm of Hamelmalo Agricultural College during summer 2015 to study the effect of dates and methods of sowing with and without hydro-priming on growth, development and yield of sorghum. The experiment consisted of 2 factors- three dates of sowing viz. D0 (Sowing before the onset of first summer rain, June 30), D1 (Sowing with the onset of first summer rains, July 7) and D2 (Sowing after the onset of summer rains, July 14) and three methods of sowing viz. SP (Direct sowing with hydro seed priming), TR (Transplanting) and DS (Direct sowing without hydro seed priming). The experiment was conducted in split plot design with 4 replications by keeping dates of sowing in the main plots and methods of sowing in the sub plots. The data on growth parameters, crop phenology, yield components and yield were recorded. The data were analysed using GENSTAT software and inferences were drawn by using LSD at 5% level of significance. Sowing methods significantly affected leaf area and leaf area index but sowing dates and their interaction with sowing methods did not show significant difference. Stand count, plant height, phenological parameters, thousand grain weight, grain and biomass yield were significantly affected by the sowing dates and methods but no significant difference in their interaction on all the parameters except in stand count and phenological parameters. Sowing before the onset of first summer rains (D0) resulted in significantly highest grain yield. Among the sowing methods, transplanting resulted in significantly higher grain yield seconded by direct sowing with hydro seed priming. Transplanting is less profitable and practicable as it is more laborious and difficult to apply in larger areas.
