Tomato leaf color as predictor of soil moisture value using machine learning techniques
Authors: Atanasov Svetoslav , Harizanova-Petrova Bilyana , Petrova Radost
Published: April 2023

Fresh water supplies for irrigation purposes must be used sparingly and judiciously, as water is an invaluable natural resource that is in short supply in much of the Earth. Soil moisture in fields is not uniform everywhere, and deploying thousands of sensors is unnecessarily expensive. The purpose of this publication is to model and predict the relationship between tomato plants leaf color, soil moisture, and thus manage the irrigation process in an optimal manner. The research was conducted using generally accepted methods, the field method, and the method of statistical evaluation of results. Machine learning algorithms (MLA) and data mining are utilized in this paper to model the relationship between RGB color values from tomato leaves and soil moisture and temperature. The color of the leaves of open field tomato plantations grown without stakes is the focus of this study. Three main tasks are fulfilled: to prove that there is a relationship between leaf color and soil moisture, to study its supposedly nonlinear type and to model this relationship with MLA. First, a classifier is trained, and then a model is created and saved. Finally, the efficiency of the chosen model is tested using a different test data set. The name “12-9-6-3” for the methodology of measurements is fgiven. It is proven that the young leaves are more informative about the need for watering. As a result, there is less than a 1% error in predicting soil moisture using the color of tomato leaves considering also soil temperature, using M5P regression model. This predictive model can be used in creation of automated systems for optimal irrigation management and water saving

Authors: Kurhak Volodymyr , Kolomiiets Larysa , Koryagin Oleksiy , Krasiuk Liudmyla , Kulyk Roman
Published: April 2023

The relevance of the results of these studies lies in the fact that until recently, changes in the mineral composition of different types of meadow agrophytocenoses under the influence of symbiotic alfalfa and mineral nitrogen in the content of macro- and microelements, heavy metals, and nitrates in feed biomass have not yet been sufficiently investigated, which hinders the development and implementation of feed production findings in agricultural production. The purpose of the study is to establish changes in the accumulation of various meadow agrophytocenoses in dry feed biomass on various agricultural zones of mineral elements during cultivation on dark grey soils of the Right-Bank Forest-Steppe. During this study, field and laboratory methods were used, and an analytical method was used to determine the mineral composition of dry feed biomass. The results of studies on the accumulation of alfalfa, alfalfa-cereals, and cereal stands in in dry feed mass on various backgrounds of fertilisation and liming of raw ash, macro- and microelements, heavy metals, and nitrate nitrogen are presented. It is shown that under the action of symbiotic nitrogen in alfalfa and alfalfa cereal stands, compared with cereals in the dry mass of feed, raw ash accumulates more macroelements, trace elements, and heavy metals by 0.6-0.8%, the ratio of calcium to phosphorus increases by 0.11-0.26, and potassium to the sum of calcium and magnesium decreases by 0.11-0.26. Under the action of mineral nitrogen in the case of the introduction of N90 in the cereal stand, the content of nitrates increases from 0.02 to 0.04%, zinc – from 9.1-9.2 to 12.4-12.6 or by 3.2-3.5 mg/kg, copper – from 3.4-3.7 to 5.3-5.5 mg/kg, as well as manganese, lead, nickel, cadmium in the dry mass of the feed of the cereal stand. It is proved that the content of macro- and microelements in the dry mass of feed corresponds to zootechnical standards for feeding cattle, and nitrates and heavy metals do not exceed the maximum permissible concentrations. The results of these studies can be used in the development of recommendations on technologies for growing perennial cereals for feed purposes and in the educational process

Dress as Deceptive Visual Rhetoric in Eliza Haywood's Fantomina
Authors: Hansen Kathryn S
Published: April 2023

Writers of fiction capitalize upon dress’s potential as an agent of deception, using clothing as a means through which characters control their identity to perpetuate lies. Eliza Haywood’s Fantomina; or, Love in a Maze (1725) contains this type of heroine, and the novella shows dress can provide women with power that they can find in few other arenas. This novella constructs lying and dress as potent related tools that allow the protagonist to achieve her desires by creating untruths that pass for realities. In so doing, Fantomina capitalizes upon two related phenomena: the cultural perception of women’s status as innately deceptive and the pervasive accusation that clothing hides the truth. This essay discusses how Fantomina celebrates deception by using clothing as visual rhetoric. To do so, it first sets out the popular association of dress with deception, paying particular attention to the hoop petticoat. A discussion of the ways in which Haywood’s heroine employs dress as visual rhetoric follows, establishing how Fantomina celebrates lying as a useful strategy for women.
Visions: "Which made it look like a gentleman’s”: Anne Lister’s Use of Lord Byron in Her Construction of a Gentlemanly Image
Authors: Olivieri Michelina
Published: April 2023

Despite the rigorous study of Anne Lister’s personal and public identities, scholars have only minimally acknowledged the ways in which Lister appropriated the ideas and practices of others to construct the image of herself they themselves are so fascinated by. From her teenage years onward, Lister collected ideas, images, and published works that broke with the traditional, conservative ideals on which she was raised and adapted them for her own use in expanding her queer identity. Of the scholars who do investigate Lister’s use of the publicly queer, even fewer have thoroughly examined Lister’s method of adaptation as a distinctly queer process of recognition and replication within the community—a process that, to some extent, still exists today. This paper aims to bridge a portion of this gap by examining Lister’s use of Lord Byron and argues that in her reflecting the easily visible traits of other, more public figures like Byron, Anne Lister exemplifies a tradition of queer survival methods that have created a community built on recognition and visibility within while maintaining the ability to hide in plain sight without, existing in the space between seen and unseen.

Last summer, a group of participants in ABO’s #WriteWithAphra program joined a co-writing group that continues to meet each weekday. When presented with ABO’s call for reflections in early 2020, we wanted to reflect as we have worked this past year: together. We share here our conversation from June 4, 2021 (edited for clarity) that addresses why we joined the writing group, as well as what we have gained, the challenges we have encountered, and why we are still here. We frame the conversation with a brief introduction that explores the feminist nature of co-writing.
“All the modes of story”: Genre and the Gendering of Authorship in the Year 1771
Authors: Mazella David , Willan Claude , Bishop David , Stravoski Elizabeth , Barta Walter , James Max
Published: April 2023

This essay argues that literary histories organized around a single genre, narratives of national formation, or canonical male authors cannot do justice to the complexities of women’s participation in eighteenth-century British genres. Instead, this essay offers an alternative approach based on the reduction of the geotemporal scope to the literary productions of a single year in three cities. Working with the ESTC records for the 2000+ items produced in these cities helped produce a dataset that allowed us to recreate each city's literary and non-literary genre system, print environment, and "historical present" for the target year. This inventory became the basis for a microhistory of women's literary and nonliterary textual production for this year, organized by city, category, and genre. From this project we learned of London's overwhelming commercial dominance for genres both literary (sentimental fiction, semifictional memoirs, religious elegy) and non-literary and "improving" (both Montagus, Macaulay, Talbot). Women in the other two cities contributed largely through salon and coterie activities or didactic/devotional writings. Finally, the temporalized notion of “perplexity” identifies a characteristic pause in action when female characters are forced to place their trust in men of unknown character: this is a scenario that plays out through a variety of genres during this year, from sentimental fiction to pro- and anti-war polemics. Our microhistorical, scaled-down approach to feminist literary history offers a version of "recovery and counter-representation" that can accommodate multiple recovery projects, fresh perspectives, and deeper inquiries into once-neglected or newly available sources.
Succubus Matters
Authors: Chow Jeremy
Published: April 2023

This essay argues that the Gothic succubus pioneers new frameworks for examining female sexuality, sexual violation, and consent in the eighteenth century. M. G. Lewis’s The Monk (1796) reveals the Bleeding Nun as a demonic female ghost that is both sadistic and hypersexualized, especially in her tryst with Don Raymond. The spectrality of the succubus reimagines the displacement of the female body as something both material and ethereal, and in so doing, renders consequent displacements of consent, agency, and sexuality, which may characterize queer Gothic tropes. I interweave discussions of consent alongside representations and theories of ghosts throughout the eighteenth century to evaluate how the succubus muddies conceptions of sexual violation and gender. To see or narrate the succubus is to grapple with maligned forms of female empowerment and eroticism, which this essay seeks to recuperate.
Teaching Charlotte Lennox’s Harriot Stuart: Romance, the Eighteenth-Century Novel, and Transatlantic Fictions
Authors: Kvande Marta
Published: April 2023

Harriot Stuart is well worth teaching because it offers rich possibilities both for discussing literary forms such as heroic romance, epistolary form, and women’s narrative voices, and for investigating topics such the transatlantic experience, colonialism, and representations of Native Americans. Whether in a course focused specifically on Charlotte Lennox’s works or in a more broadly focused course in eighteenth-century fiction, Harriot Stuart can help students learn about the possibilities for women’s empowerment and about transatlantic and racial ideas during the period.
Cooking Up Knowledge: Materiality, Recipes, and Jane Barker’s A Patch-Work Screen for the Ladies
Authors: Boettcher Carolin
Published: April 2023

The recipes included in Jane Barker’s A Patch-Work Screen for the Ladies (1723) appear to be some of the most jarring and out-of-context inclusions in the narrative. This article explores the relationship between Barker’s novel and the form of the recipe collection in the late seventeenth and early eighteenth centuries on both a material and an epistemological level. The entanglements between recipes and the patchwork screen not only point to the processes of constructing and conveying knowledge, but also to the materiality of these processes as Galesia and the Lady build the patchwork screen. Her focus on the materiality of knowledge reinforces Jane Barker’s deep engagement with natural philosophy, the natural world around her, as well as domestic practices when the characters sew literal pieces of paper with poems on cookery and natural philosophy into the patchwork screen. The material and structural influence of the recipe on Barker’s narrative constitutes an additional layer underneath the reigning metaphor of the patchwork screen and textiles in more general. Considering the recipe and recipe collections as underlying metaphors in addition to the patchwork increases the generically experimental character of the Patch-Work Screen.
Hannah Humphrey, London’s Leading Caricature Printseller
Authors: Contogouris Ersy , Denis Béatrice
Published: April 2023

Hannah Humphrey (ca. 1745-1818) was the exclusive publisher of James Gillray's (1756-1815) caricatures from 1791 until Gillray's death. His achievements were made possible in large part thanks to Humphrey and her innovative business acumen. But while Gillray has been celebrated and studied by art historians, Humphrey’s contribution to his success and to the history of graphic satire has remained unexamined. This article is a first attempt to shift the focus onto her in the story of the “golden age” of British caricature. It outlines Humphrey’s career, takes a closer look at her relationship with Gillray, and finally considers some of the reasons she has remained in the shade.

Thermodynamic basis for refi ned calculation of the operating cycle of a reciprocating internal combustion engine
Authors: Matiukhin L. M.
Published: April 2023

Introduction (problem statement and relevance). The notion of “charge coeffi cient” used only by the engine building specialists has a number of signifi cant disadvantages, since this coeffi cient characterizes not the charge as such, but only its deterioration. In particular, it is impossible to specify its limit value, at which the maximum engine power is achieved.The purpose of the study is to search for a parameter alternative to the charge coeffi cient and quantitatively determining the charge degree of the total cylinder volume with the incoming charge. The parameter shall unambiguously estimate the charge reserves and the limit value one shall aim at in order to achieve the maximum engine power with no incoming charge losses as a result of scavenging.Methodology and research methods. In order to solve the assigned task, thermodynamic analysis of gas exchange results was used, on the basis of the ratios of the components of the resulting air-fuel mixture.Scientifi c novelty and results. The paper proves that the charge is unambiguously characterized by the basic technical notion of a proportion – a proportion of incoming charge σСЗ in the air-fuel mixture. Accordingly, the proportion of residual gases representing diff erence σr= 1 σСЗ allows estimating the degree of internal recirculation and, on the other hand, characterizes the charge reserves.Practical signifi cance. The suggested approach allows taking into account the infl uence of the used fuel type (its molar weight), external recirculation and (variable) valve timing on the charge. Thus, it is possible to relate the charging up coeffi cient to the purifi cation coeffi cient as well as to decrease the number of independent variables when conducting thermal calculation of the operating cycle of the reciprocating internal combustion engine, which ultimately simplifi es its performance.
Method for increasing heat removal effi ciency of a cooling system radiator of an electric motor vehicle of category L
Authors: Bazavluk S. A. , Lyubimov I. A. , Kurmaev R. Kh. , Soldatov I. V.
Published: April 2023

Introduction (problem statement and relevance). At low vehicle driving speeds, when the ram airfl ow is minimal or completely absent, the airfl ow created by the radiator fan is of high importance for the heat removal. In this paper, the airfl ow through the radiator created by the radiator fan was used as a criterion of the heat removal effi ciency, which is calculated from the pressure drop in the radiator for various fan speeds. The possibility of increasing the airfl ow through the radiator by increasing the distance between the fan and the radiator through improvement of the casing design was considered.The purpose of the study is to analyze the infl uence of the radiator casing design on the heat removal effi ciency of the cooling system radiator.Methodology and research methods. The static pressure created at diff erent fan speeds was defi ned at the radiator inlet and outlet in 32 points (16 on each side) using the air pressure probes. The pressure readings were recorded using a 64-channel pressure scanner.Scientifi c novelty and results. The paper deals with research into the infl uence of the distance between the fan and the cooling system radiator surface on the heat removal effi ciency by increasing of the airfl ow through the cooling system radiator. The results of the experiment to determine the optimal distance between the radiator and the fan for various rotational speeds are presented.Practical signifi cance. The value of the distance between the fan and the radiator was determined, which makes it possible to achieve an increase in the airfl ow through the radiator due to more uniform distribution of the airfl ow created by the fan mounted on the radiator casing over the radiator surface

Authors: Rumyantsev V. V. , Lushcheko V. A. , Mavleev I. R. , Pavlenko A. P.
Published: April 2023

Introduction (problem statement and relevance). The environmental requirements for vehicle engines becoming more stringent require development and introduction of high-performance turbo chargers. Transition from external to internal varying, namely to the variable nozzles of the turbine, is caused by the necessity to reduce the transient process time during operation of the engine and the vehicle itself.The purpose of the study is development and confi rmation of the methodology (general strategy) for designing and modernization of radial-axial turbines with variable nozzles.Methodology and research methods. The study used the combination of calculation models for the engine itself with preliminary verifi cation based on the results of tests on the engine test bench (AVL BOOST, CRUISE M), gas-dynamic calculation of the turbine stage with determination of geometric parameters of the blade ring, housing (volute) and blade drive mechanism, their geometric modeling (Siemens NX) followed by 3D models export, CFD simulation of the stage fl ow including taking into account the transfer element (with impeller rotation) and generation of the stage curves (AVL FIRE).Scientific novelty and results. Combination (synthesis) of calculation models of different levels makes it possible to determine geometric parameters of the turbocharger turbine with variable nozzles providing high effi ciency (performance factor) of the turbine stage with a simultaneous shift of the maximum torque mode of the engine itself to the area of lower crankshaft rotation rate (along the full-load curve).Practical signifi cance of the paper consists in reduction of the time of design and subsequent refi nement (experimental) works during creation and modernization of turbines with variable nozzles of small-sized turbochargers. The obtained values of relative geometric parameters can be used at the design stage
crises
Authors: Grigoryeva Elena
Published: April 2023

One British publishing company has chosen ‘permacrisis’ as the word of the year for 2022. In fact, the crisis has been permanent for the time longer than one year. Over the last few decades, crises have become so integrated into our lives that they look like a familiar and permanent backdrop. Crises of all kinds succeed one another: economic, epidemiological, ideological, political ... But in spite of everything, life goes on and the end of a difficult year was brightly coloured by regional conferences, governor’s prizes (14–22), glorious anniversaries and accompanying magnificent exhibitions (8–13) in the field of architecture.The first part of the issue’s main section is devoted to different kinds of crises: complex, professional, energy and climate ones. Crisis phenomena are found even in the sphere of toponymy and architectural details. Paradoxically, any crisis is also a window of opportunity, and this is the focus of the second part of the issue’s main section.The issue about crises would not be complete without the heritage section. Despite the devoted work of restoration architects (14), researchers of the history of regional architecture (120–160) and certain achievements in comprehensive regeneration of quarters in Russian cities, heritage has firmly stuck in permanent crisis, and the “protected by the state” signs often don’t calm down, but rather provoke rejection because of their discrepancy with harsh reality.

Architectural design and ontological crisis
Authors: Kapustin Petr
Published: April 2023

The state of permanent crisis has become almost a norm for contemporary humanity. However, one cannot deny that for modernist tendencies in art, literature and culture in general, crisis is the most comfortable state: it raises the stakes for innovation, allows radicalism, and demands strong methods and strong personalities. The trend, alas, is not limited to modernism as a period. Architecture, prone to expressive ‘beautiful gestures’ and aimed at acute emotional impact, even today fosters the spread of ontological crisis, while cluttering the mental sphere.
The crisis of a detail as a detail of the crisis
Authors: Bagina Elena
Published: April 2023

The birth of a new post-crisis architecture, human-scaled and reflecting deep philosophical and ideological foundations of the society, is possible if these foundations are not destroyed. The crises experienced by architecture in the 20th and early 21st centuries are related to the loss of ideological foundations of the society. The disappearance of symbolic details in architecture is a detail of the general crisis of culture.

It is a dual phenomenon, which is also a space of danger, risk and opportunities for self-development / self-realization.
A theoretical model of the artistic and architectural object
Authors: Volichenko Olga , Imankulov Jumamedel , Marchenko Anastasia
Published: April 2023

Research in architectural history is consistently based on three models of the architectural object: classical, monostructural and polystructural. In order to understand the methods and principles of modeling the architectural object, the authors consider the stages of methodological understanding of the model of the artistic object by outstanding philosophers and art historians, who addressed the problems of aesthetic worldview. It is noted that the contemporary architecture, gravitating toward artistic openness, semantic streamlining, polysemy and vagueness, can also be presented as the unity of the natural, artificial and conditional.

Published: April 2023

Understanding IT continuance and its extension has been important in information systems field. By amending Bhattacherjee’s IT continuance model, we examine why consumers continue using an online shopping channel for product purchase. We use confirmation on product quality, confirmation on post-sales service, psychological contract fulfilment, and satisfaction to explain consumers’ attitude toward, and intention of, online shopping continuance. The results indicate that all the hypothesized relationships proposed in this study are significant at least at p-value < 0.01 level, demonstrating that product quality, post-sales service, psychological contract, and satisfaction are pivotal for consumers to repurchase products with that online channel. Detailed findings and conclusions for academics and practitioners are presented.
An Investigation Into Organoleptic Evaluation and Phytochemical Screening of Dried Powdered Peel, Pulp of Ripped Pawpaw, Production Fresh Pawpaw Juice and Sensory Evaluation of the Pawpaw Juice
Authors: Koroma Lahai , Gandhi Dolly Anna , Lebbie Victoria
Published: April 2023

Organoleptic evaluation and phytochemical screening were carried out on dried powdered pawpaw peel, pulp of ripped pawpaw. Organoleptic characters investigated were size, colour, odour, taste and texture of the dried powdered pawpaw peel, pulp and the pawpaw drink. Phytochemical screening involved testing each of dried powdered pawpaw peel and pulp for different classes of secondary plant metabolites. The methods used for detection of the various phytochemicals include qualitative chemical tests to give general idea regarding the nature of constituents present in the different solvent extracts of the powdered Pawpaw peel and pulp. The powdered peel was found to be brown in colour, sticky and tasted bitter indicating that the peel contained alkaloids. The sweet taste of the pulp indicates the presence of carbohydrates. The results of phytochemical screening indicated that the dried powdered peel of ripped pawpaw fruit tested positive for starch, glucose, proteins, sterols, Alkaloids, tannins, flavonoids and phenolic compounds, fats and oils, glycosides and saponins while the driedpulptested positive for starch, glucose, glycosides and saponins. The dried Powdered peel of ripped pawpaw fruit contains more secondary plant metabolites than the dried pulp. It is therefore suggested that the peel should be included in the future formulation of the Pawpaw Juice. The results of the sensory evaluation of the Pawpaw Juice served to 40 semi-untrained panellists randomly selected from the various Departments of the Eastern Technical University of Sierra Leone indicated that the colour (75%), taste (87.5%), aroma (80%) and texture (60%) were general acceptable and good. It can therefore be used as food supplement for children.
The Impact of Implementing Asymmetric Auto Reject on Liquidity and Stock Trading Volume (Case Study on LQ45 Stock in Indonesia Stock Exchange)
Authors: Pramana Made Surya
Published: April 2023

The existence of the Covid-19 pandemic has greatly affected the condition of the public in investing, especially investing in stocks. The Indonesia Stock Exchange as a stakeholder makes several regulations so that the public continues to have a high interest in investing in stocks one of which is the application of an asymmetric auto reject policy. This study was conducted with the aim to explaining whether there is an effect before and after the implementation of the asymmetric auto reject policy on liquidity and stock trading volume. This study uses the paired sample test method to see whether there are differences before and after the implementation of the asymmetric auto reject policy. The result of this study indicate that the significance value (2- tailed) of the paired sample test table is <0.05 which indicates a significant difference between the initial and final variables. This shows that there is a significance influence on liquidity and stock trading volume in LQ45 stocks.
Reference Based Pricing for Employee Healthcare Needs
Authors: Spreat Scott , Buchanan Bruce
Published: April 2023

Agencies that provide supports and services to individuals who have intellectual and/or developmental disabilities operate within a system in which governmental agencies typically control the price to be paid for the provision of these supports and services. One consequence of the imposition of these fixed prices is a chronic shortage of those staff who provide direct supports and services to people who have disabilities. Because agencies have no control over the prices they can charge for the provision of supports and services, they are unable to raise staff wages sufficiently to create an equilibrium between supply of and demand for staff. Instead, equilibrium must be sought by cost reduction measures. Strategies to reduce costs are essential to the continuation of this service model as substantial increases in governmental funding are unlikely. Reference based pricing for employee health insurance is described and proposed as a cost reduction strategy within the intellectual and developmental disability community. An example of the adoption of this strategy within the intellectual disability field is provided.

The Impairment of Symbolic Semantic Functions in Autistic Adolescents
Authors: Labiadh Lazhar , Megalakaki Olga , Vitiello Damien , Hanneton Sylvain , Oboeuf Alexandre , Baati Narjes
Published: April 2023

In autism, motor impairments are extremely common and often herald the emergence of ubiquitous atypical development. Few studies so far have explored the autistic motor difficulties. Our work aims to investigate the level motor management of adolescents with autism spectrum disorder, compared to typically developing children. The motor management was realized, in different imitative conditions. We assume that pragmatic sensorimotor management would be functional both in adolescent with autistic spectrum disorder and typical children. However, if high-level cognitive semantic management is gradually acquired in the typical children, it would be deficient in the adolescents with autism spectrum disorder.

Chronic obstructive pulmonary disease (COPD) was the fifth leading cause for early death and disability in 2020 with approximately 2.75 million deaths per year, which was 4.8%in total from the general mortality. Right ventricular hypertrophy with preserved systolic function is the most common finding in patients with COPD. The development of pulmonary hypertension leads to DV (right ventricle) dilatation and DV heart failure during the course of the disease. Material and methods: The design of the research was a prospective-clinical cross-sectional study as we analyzed 94 patients with COPD. All patients were divided in groups according to the degree of obstruction and classified by the GOLD classification system into four groups from GOLD 1 – GOLD4. All of our patients were analyzed thoroughly on admission and during hospital stay. ECG was made, Nt-proBNP analysis and basic and advanced echocardiography evaluation. Natriuretic peptides were measured and processed by commercially available assays with excellent precision where cut-off value was 125pg/ml. Echo analysis was done by Vivid 7 echo machine with a special feature to right heart chamber characteristics. Results: In terms of risk factors, hypertension, diabetes mellitus and hyperlipidemia were examined in all 94 patients in our study. Arterial hypertension was present in half of the patients, 51.06%. Diabetes mellitus was present in 19.15% of analyzed patients. The analysis of Nt-proBNP level in our study showed that the average value of this natriuretic peptide was above reference range and it was 236.27pg/ml. The highest average values of NT-proBNP were registered in GOLD class 3, while the lowest average and maximum value of NT-proBNP was found in GOLD class 2. According to the results of the Tukey post-hoc test, there was a statistically significant difference in Nt-proBNP levels between GOLD class 2 and GOLD class 3. The average values of Nt-proBNP in the group of patients with acute exacerbation was far higher than in the group of chronically stable patients. The difference between the two groups was 3.5 times in GOLD class 3 and approximately 2 times in GOLD class 4. Conclusion: BNP and NT-proBNP are natriuretic peptides that are secreted under conditions of cardiac stress and weakness. They are established biomarkers and are listed in the guidelines for chronic heart failure as they are quantitative markers used for diagnosis and risk stratification. Still, more studies with a larger number of patients are needed to confirm the role of Nt-proBNP in patients with COPD in different stages of GOLD and progression of the disease.

The CADTH Horizon Scanning Service identifies emerging health technologies that may be of potential interest to health care decision-makers in Canada.

Chronic pain, including chronic low back pain, challenges many aspects of people's lives, including social, physical, mental, and professional. Approximately 80% of adults will be affected by chronic lower back pain at least once in their lifetime and seek out multiple treatment options, including drug treatments, psychological treatments, and physical therapies.

This Horizon Scan summarizes available information regarding an emerging technology, the Erchonia FX 635 low-level laser system, for the treatment of chronic low back pain.
Policies on Requirement for Geographical Responsive News Affects News Coverage in Print and Social Media Channels in Kenya

Geographic proximity is one of the most frequently occurring factors that contribute to newsworthiness. Journalism places an emphasis on proximity in its selection criteria for news stories, which prioritize cultural and geographical proximity as one of their primary considerations. Because of this, the aspect of newsworthiness that is most dependent on whether or not the piece of information being delivered has an influence on the audience of a news outlet. Yet, less research has been done on the part that proximity plays in the geographical locations nearby. In light of this, the purpose of this study was to evaluate the extent to which policies on the demand for geographically responsive news affect news coverage. The news coverage provided by Nation Media Group was subjected to a quantitative content analysis with a sample size of sixty. In light of this, the study prompted the respondents to provide their responses to a series of statements in order to establish the extent to which policies on the demand for geographically responsive news effect news coverage in print and social media channels in Kenya. According to the findings, media outlets frequently fail to respond to the need for local news because their attention is directed toward achieving the editorial policy standards for geographically balanced news coverage. In addition, journalists frequently have to deal with competing demands on their attention, which increases the likelihood that they will not adequately explore local news on matters of public interest. This ultimately results in inadequate coverage of the news. According to Pearson correlation, there was a statistically significant association between balanced geographical news coverage and news coverage (r=0.476, p<0.05). Based on these findings, the research hypothesis: HO: Editorial policies on demand for balanced geographical news coverage have no significant effect on the coverage of news in print and social media channels in Kenya. Based on the findings, the hypothesis was rejected. Analysis of Variance (ANOVA) shows that balanced geographical news coverage could statistically and significantly predict news coverage, according to an analysis of variance (F=13.795, P<0.05). This was attested to by regression coefficients (t=3.714, p<0.05) that showed that balanced geographical news coverage) could statistically significantly predict news coverage, according to t-test results. The results suggest that geographical news coverage affects how news is covered. This could go on to impact the propensity of news coverage to contribute to social transformation in Kenya.

BACKGROUND: Preparation of turmeric extract gel with a concentration of 10% and comparing it with non-eugenol gingival dressing (Coe-PakTM) in the healing and re-epithelialization of palatal donor site after free gingival graft, and reduction of postoperative pain.MATERIALS AND METHODS: This study was conducted on twenty-two patients with lack of attached gingival tissue for various reasons and received soft tissue augmentation via free gingival grafts. Participants were randomly divided into two equal groups: group I (test) was treated with 10% turmeric gel while group II (control) was treated with (Coe-PakTM). Both pain level index which assessed by using the Visual Analogue Scale (VAS) and Analgesic consumption index were recorded for 7 days after surgery. The healing index, the color match index, and the re-epithelialization index were assessed on days 7, 14, 21, and 28. Finally, wound size index was measured via periodontal Probe at baseline and days 7, 14, 21, 28, and after 2 months.RESULTS: Group I showed significant pain reduction measured by VAS and analgesic consumption on day 3, 4, 5, 6, 7 (p<0.05) with no significant difference on the first two days (p>0.05). Group I demonstrated significant acceleration in the initial healing process during the 1st week (p=0.002) and 2nd week (p=0.01) with no significant difference between both groups in the 3rd and 4th weeks (p>0.05). Group I showed statistically higher VAS for the color match on day 7, 14, 21, and 28. No statistical difference was noted between the groups after two months. There was no statistical difference between groups I and II in the re-epithelialization and wound size index at any of the follow-up periods (p>0.05).CONCLUSION: 10% turmeric extract gel showed relief of post-operative pain, acceleration of the healing process, and better outcomes in terms of the color match for the palatal wound after free gingival grafting procedure comparing to the Coe-PakTM periodontal dressing.KEYWORDS: Curcumin; Free gingival graft; periodontal dressing; donor site
