Analyzing Language in the Picnic Scene Picture and in Conversation: The Type of Discourse Sample We Choose Influences Findings in People With Aphasia
Authors: Leaman Marion C. , Edmonds Lisa A.
Published: May 2023

Purpose:

People with aphasia express that improved conversational discourse is a primary rehabilitation goal. Discourse is usually assessed using monologue, such as a picture description task, but research shows that language in monologue varies from language in everyday conversation. Consequently, we investigated the relationship of language in unstructured conversation and in the picnic scene picture because it is a part of the most often used aphasia battery (Western Aphasia Battery–Revised) and thus is frequently used to inform therapy. Second, because previous research suggests people with severe aphasia may not demonstrate language production variability between types of monologue-level discourse, we evaluated the relationship of severity and the difference in scores between conversation and the picnic scene task.

Method:

Thirty-four people with mild-to-severe aphasia described the picnic scene and provided a conversation sample. We measured language production and communicative success using seven measures with established psychometrics in conversation/monologue. We conducted correlations to answer the research questions.

Results:

Correlations were moderate and weaker for the measures in the two conditions. A strong negative relationship was demonstrated between aphasia severity and global coherence. All other relationships were moderate and weaker for the remaining measures when correlated with aphasia severity (also negative).

Conclusions:

Results are consistent with other studies indicating that language varies in different types of discourse. We conclude that for accurate, meaningful assessment, discourse sampling needs to include the specific type of discourse the individual wishes to address in therapy, because discourse samples and their findings are not interchangeable.
The Effect of Genetic Taste Status on Swallowing: A Literature Review
Authors: Lee Theresa S. , Dietsch Angela M. , Damra Rana H. , Mulheren Rachel W.
Published: May 2023

Purpose:

Swallowing and taste share innervation pathways and are crucial to nutritive intake. Individuals vary in their perception of taste due to factors such as genetics; however, it is unclear to what extent genetic taste status influences swallowing physiology and function. The purpose of this review article is to provide background on genetic taste status, review the evidence on the association between genetic taste status and swallowing, and discuss research and clinical implications.

Method:

A comprehensive literature review was conducted using search terms related to swallowing and genetic taste status. Studies were included if they investigated the main effect of genetic taste status on swallowing or the interaction of genetic taste status with other variables. Studies were grouped by participant population (healthy participants or persons with a swallowing disorder), swallowing-related outcome measure, and method of genetic taste status measurement.

Results:

The results were mixed, with five of 10 reviewed studies reporting a statistically significant main or interaction effect on swallowing. Most studies included healthy participants, with only one study investigating participants with dysphagia. Additionally, swallowing-related outcome measures and methods of determining genetic taste status varied greatly between studies conducted on separate cohorts.

Conclusions:

Few studies have incorporated genetic taste status as a variable in swallowing research, and results are mixed. Future research on sensation and swallowing should consider the potential effect of genetic taste status and follow standardized procedures for its determination. Despite the limited evidence, clinicians may consider how individual differences in perception shape swallowing outcomes.
Accepting Things as They Are: Dispositional Mindfulness, Decentering, Self-Compassion, and the Impact of Stuttering on Adults Who Stutter
Authors: Israel Shiran , Reuveni Omer , Glick Ittai , Levit-Binnun Nava
Published: May 2023

Purpose:

Mindfulness is defined as intentional, present-moment, nonjudgmental awareness. Previous studies have proposed that mindfulness practice may benefit people who stutter. This study aimed to test the relationship between levels of dispositional mindfulness in people who stutter and the impact of stuttering and whether self-compassion and the metacognitive ability of shifting to an objective perspective (decentering) mediate this relationship. It is hypothesized that greater dispositional mindfulness is associated with attenuated negative impact of stuttering on a person's life through a higher capability to shift into an objective and compassionate perspective.

Method:

A total of 150 Israeli adults who stutter completed a full online survey in Hebrew to assess their levels of dispositional mindfulness, self-compassion, decentering capability, and impact of stuttering on their lives. The relationships between constructs were assessed using Pearson's correlation and mediation analysis.

Results:

The adverse impact of stuttering was negatively and moderately associated with dispositional mindfulness, such that individuals with greater self-reported dispositional mindfulness reported fewer reactions to stuttering, difficulty in communication, and higher quality of life. This relationship was fully and sequentially mediated via decentering and self-compassion, which were also negatively and moderately associated with the impact of stuttering.

Conclusions:

People who stutter with greater dispositional mindfulness have an increased ability to view their experiences in a more objective and compassionate manner, which is associated with an attenuated impact of stuttering on their lives. As these capabilities can be cultivated through practice, this study proposes mindfulness practice as an additional beneficial tool for people who stutter.

Published: May 2023

The global economy has been dramatically impacted by COVID‐19, which has spread to be a pandemic. COVID‐19 virus affects the respiratory system, causing difficulty breathing in the patient. It is crucial to identify and treat infections as soon as possible. Traditional diagnostic reverse transcription‐polymerase chain reaction (RT‐PCR) methods require more time to find the infection. A high infection rate, slow laboratory analysis, and delayed test results caused the widespread and uncontrolled spread of the disease. This study aims to diagnose the COVID‐19 epidemic by leveraging a modified convolutional neural network (CNN) to quickly and safely predict the disease's appearance from computed tomography (CT) scan images and a laboratory and physiological parameters dataset. A dataset representing 500 patients was used to train, test, and validate the CNN model with results in detecting COVID‐19 having an accuracy, sensitivity, specificity, and F1‐score of 99.33%, 99.09%, 99.52%, and 99.24%, respectively. These experimental results suggest that our strategy performs better than previously published approaches.
Automated issue assignment using topic modelling on Jira issue tracking data
Authors: Diamantopoulos Themistoklis , Saoulidis Nikolaos , Symeonidis Andreas
Published: May 2023

As more and more software teams use online issue tracking systems to collaborate on software projects, the accurate assignment of new issues to the most suitable contributors may have significant impact on the success of the project. As a result, several research efforts have been directed towards automating this process to save considerable time and effort. However, most approaches focus mainly on software bugs and employ models that do not sufficiently take into account the semantics and the non‐textual metadata of issues and/or produce models that may require manual tuning. A methodology that extracts both textual and non‐textual features from different types of issues is designed, providing a Jira dataset that involves not only bugs but also new features, issues related to documentation, patches, etc. Moreover, the semantics of issue text are effectively captured by employing a topic modelling technique that is optimised using the assignment result. Finally, this methodology aggregates probabilities from a set of individual models to provide the final assignment. Upon evaluating this approach in an automated issue assignment setting using a dataset of Jira issues, the authors conclude that it can be effective for automated issue assignment.

The European flat oyster, Ostrea edulis, is a habitat-forming bivalve which was historically widespread throughout Europe. Following its decline due to overfishing, pollution, sedimentation, invasive species, and disease, O. edulis and its beds are now listed as a threatened and/or declining species and habitat by OSPAR. Increasing recognition of the plight of the oyster, alongside rapidly developing restoration techniques and growing interest in marine restoration, has resulted in a recent and rapid growth in habitat restoration efforts. O. edulis seed supply is currently a major bottleneck in scaling up habitat restoration efforts in Europe. O. edulis has been cultured for centuries, however, research into its culture declined following the introduction of the Pacific oyster, Crassostrea gigas to Europe in the early 1970 s. Recent efforts to renew both hatchery and pond production of O. edulis seed for habitat restoration purposes are hampered by restoration project timelines and funding typically being short, or projects not planning appropriately for the timescales required for investment, research-and-development and delivery of oyster seed by commercial producers. Furthermore, funding for restoration is intermittent, making long-term commitments between producers and restoration practitioners difficult. Long-term, strategic investment in research and production are needed to overcome these bottlenecks and meet current ambitious restoration targets across Europe.

Influence of process parameters on magnetic abrasive machining efficiency
Authors: Romanov P.I.
Published: May 2023

The development of modern mechanical engineering forces us to constantly improve the technology of processing materials and look for ways not only to improve the quality of products but also to increase the efficiency of the processing process itself. This article discusses an alternative method to finish the product, which can replace the traditional method of grinding, magnetic abrasive treatment. This is a modern solution that allows you to obtain high surface quality of the processed product with minimal defects in their surface layer, and reduce the number of technological operations, which has a beneficial effect on the efficiency of the processing process. The efficiency of the magnetic abrasive machining process, which was determined by the amount of specific removal of the material, is influenced by many parameters, some of which were studied in this article: electromagnetic induction and processing time. The success of the application of magnetic abrasive treatment can also be judged by the topography of the surface of the product made using an electron microscope. The data obtained in the course of the study demonstrated the importance of individual input parameters of the magnetic abrasive treatment process in the formation of the surface layer of the product. According to the results of experimental studies, the dependences of the varied parameters were determined and recommendations were formed to improve the efficiency of the use of the magnetic abrasive process.

Published: May 2023

Automation of the technological process of product manufacture via the application of contemporary management techniques is one approach to boost the production efficiency of the textile industry. Many characteristics of the manufacturing technology equipment should be considered in these techniques. This paper aims to present an algorithm for the synthesis of an automatic control system for the process of pulling the tape, based on the application of the predictive control method. To improve the quality of control by reducing the static error and over-regulating the transient process, an integral component was introduced into the control system circuit, which allows us to give the properties of the astatism of the system, taking into account the implementation of restrictions imposed on state variables and setting influences. Based on the comparative analysis, the advantages of the proposed approach are determined, which allows ensuring good performance of the control system in conditions of various types of disturbances. The proposed algorithm is versatile and can be applied to a control system, provided that strict restrictions are imposed on the control object on the disturbing effects and on the dynamic properties of the object.

Making candied fruits from fresh fruits is a processed product that can increase the shelf life of the fruits by many years. The processing of fruits and grapes to produce high-value food products can be done without destroying the cultivated crop. Candied fruits, for example, are a processed product made from fresh fruits that can significantly prolong their shelf life for many years. Research was conducted in 2021-2022 at the Scientific Research Institute of Horticulture, Viticulture and Winemaking named after Academician M. Mirzaev “Department of Storage and Processing of Fruit and Grapes”. The results depicted that the dry matter content of candied fruits was generally higher than 70-75%, which was consistent across most sources. An analysis of processed products made from grain fruits showed that candied fruits made from apricots had a dry matter content of 94.5-97.2%, while peaches had a dry matter content of 93.8-95.1%, and plums had a dry matter content of 85.7-88.6%. It is worth noting that apricots and peaches contained particularly high levels of dry matter.

There are phenomena that are significant to research because of how they grow and change through time in practically every discipline. One could attempt to direct a process, forecast the future using knowledge of the past, or characterize the distinctive aspects of a series using a finite quantity of information. The techniques used to handle time series are heavily influenced by the techniques created by mathematical statistics for distribution series. The most basic to the most complicated time series analysis techniques exist in statistics today. The article discusses the statistical analysis of a time series, specifically the average yield of cotton in the Kashkadarya region, Uzbekistan, and the Republics, using data from the Central Statistical Office of Uzbekistan from 2001 to 2020. The study involved constructing point and interval estimates for the average cotton yield with a 95% guarantee, identifying different types of trends, and predicting future yields for the region. Through the use of the Durbin-Watson statistical criteria, it was discovered that there is an autocorrelation dependence in the average cotton yield, indicating that the yield for the current year is dependent on yields from past years. The methods used in this study can be applied to further research conducted by students and scientists.

Authors: Umarov Muhammad , Inomov Bekzod
Published: May 2023

The soil is a vital and valuable public resource that forms the foundation of a country's prosperity and supports its productivity. Its importance primarily derives from its essential role in agriculture, which is a key factor in a nation's economic growth and stability. In order to assess the effectiveness of corn as a protective crop in increasing resistance to soil erosion, a field experiment was conducted involving four treatment options for cotton crops. The first option served as a control, using the typical fertilizer rates found in local farming practices (N250 P150 K80), and growing cotton without any additional measures. The results depicted that Corn strips that were 20-25 meters wide were effective in shielding cotton crops from wind. The width of the cotton crop, however, varied from 130-135 meters, contingent upon the mechanical composition of the soil. Our observations suggested that the bulk of wind-borne dust (also known as “dust”) traveled at a height of 0-50 cm, which could enter the cotton plants and harm them.

The issue of propagating parasitic insects in artificial food environments has been a challenge for researchers for a long time. Breeding one Trichogramma insect requires a lot of grain products and labor, and it takes about 40-50 days for Trichogramma and 55-60 days for Bracon to reproduce. This study aimed to develop a technology for the in vitro reproduction of trichogram, which are important parasitic entomophages in the control of various agricultural pests. The results of the experiments showed that the Trichogramma chilonis damage to nests with offspring was 82.4%, larvae emerged from eggs in 1.7 days. The larvae developed in this nutrient medium for 5.0 days, and the pupation period was 4.5 days. The average time from egg to imago was 11.2 days. The survival of hatchlings from the feeding medium lasted 5.4 days, and the male:female ratio (♂:♀) of hatched Trichograms was 1:6.

This article describes the results of the research conducted on the drying of different types of apricots. Experiments were conducted to study the chemical composition of apricots, the quality of the finished product after drying in three different ways, and the duration of drying. During the research period, the biochemical composition of fruits selected as raw materials was regularly analyzed. The highest indicator of the amount of dry matter in the composition was observed, and three-year average indicators were studied. Sugar is the main part of the dry matter content of apricots. Also, the content of sugar is an important indicator of the organoleptic properties of fresh and dried apricots. During the experiments, the sugar content of the selected apricot varieties was measured over the years, and average sugar content indicators were determined. Apricots are dried in three different ways - naturally, in special drying equipment with solar batteries, and artificially in laboratory conditions in the dryer data based on drying experiments are presented.

Tuberculosis (TB) is a lung infection caused by the bacterium Mycobacterium tuberculosis (MTB). TB is a leading cause of death globally, accounting for approximately 1.5 million deaths per year. The aim of this article was to evaluate the immunological role of Interleukin (IL) 18 and Interleukin 22 in patients infected with MTB and multi-drug resistant tuberculosis MDRTB. A total of 182 individuals suspected with MTB admitted to the tuberculosis center in AL-Najaf City, Iraq. A sputum acid-fast stain was performed for each individual and GeneXpert® heminested real time PCR has been performed for MDRTB detection. The two Interleukins was measurement in serum of infected individual using ELISA technique. Out of 182 individuals, there were 20 infected with MTB and 15 infected with MDRTB. Serum IL18 and IL22 levels were significantly elevated (P<0.05) in patients with MTB and MDRTB groups as compared with control subjects. The MDRTB group showed higher serum IL18 and IL22 levels (P<0.05) than the MTB group. This study showed that IL18 and IL22 had a relationship with MTB and might be used to help diagnose TB; Clinical diagnosis of TB may be aided by these tests.

Urinary tract infections (UTIs) are one of the most common medical conditions in women and men. They are caused by bacteria that enter the urinary tract through the urethra or the skin around the genitals. In this study, 102 urine samples were collected from 74 patients infected UTIs and 28 patients infected with urinary tract infections with kidney failure (UTIs-KF) admitted to a general hospital in AL-Najaf City, Iraq, between October to 2022 and March 2023 and 30 healthy individuals as control group. Standard laboratory methods were used to culture urine and to diagnose all bacterial isolates that were grown on laboratory media. The levels of cytokines IL-6 and IL-33 were detected by ELISA technique in the serum of control and patients. The results proved that age group 41-50 years old was the most UTIs infected with 31 patients (30.3%) followed by the age group ≤51 with 25 patients (24.5%). Out of total of 102 urine samples, there were 106 bacterial isolates, E.coli was the most dominate bacteria with 50 isolates (47%) followed by K.pneumoniae 18 isolates (17%), P.mirabilis 13 (12.7%), S.saprophyticus 10(9.5%), S.aureus 9(8.5%) and E.faecalis 6(6%). IL-6 and IL-33 were significantly higher in the UTIs and UTIs-KF patients, compared with the control group.

The article presents the results of landscape differentiation of the territory of the Kilemarsky section of the projected National Park Nizhegorodskoe Zavolzh'e, performed at the hierarchical level of landscape types. The territory of the Kilemarsky section of the projected national park lies in the Eurasian taiga (coniferous forest) botanico-geographical area, in the subzone of the southern taiga. According to the botanico-geographical zoning of the European part of Russia, its territory belongs to the Kama-Pechera-West Ural subprovincion of the Ural-West Siberian taiga province. The specifics of the national park's operating mode require functional zoning of the territory, taking into account the vulnerability of natural complexes, permissible recreational pressure and areas of propagation of rare plant and animal species, which determines the high demand for landscape zoning schemes, necessary for the effective organization of environmental and recreational activities. The article presents a scheme of landscape zoning of the territory of one of the five sections of the projected National Park Nizhegorodskoe Zavolzh'e – Kilemarsky. The work was carried out on the basis of field and desk researches, conducted in 2022. During the research seven landscapes were identified and briefly characterized.
Environmental benefits of intelligent transport systems implementing
Authors: Wajeetongratana Songserm
Published: May 2023

Intelligent Transportation Systems (ITS) have been shown to have positive effects on the economy and on efficiency, but this study aims to show that they also have a positive effect on carbon emissions. This article is based on the premise that implementing these technological steps is a winwin for long-term economic and ecological viability. The first research question asks if there is evidence that ITS systems can be implemented and operated in a way to generate environmental benefits, and the second asks if the policy priorities of national and international stakeholders reflect a propensity for ITS deployment in order to yield those benefits. Both fundamental drivers and a synthesis of the empirical facts are used to provide an answer to the first question. New propensity models to accomplish climatic and environmental objectives are one solution to the second problem. According to the findings, the likelihood that ITS would be included as a high priority policy instrument in future transport policies is significantly influenced by the Vehicle Density and High Technology exports of a country. The study's significance lies in its promotion of ITS as a policy instrument with the potential to improve economic performance and environmental performance. It's useful for transport planners and policy experts on a global, national, and even regional scale.

The content of the article is based on the classical provisions of mechanics (the Dalembert principle) for non-ideal communication. The analytical proof is given that the linear acceleration of the car with its equally accelerated movement along the descent part of the sorting slide depends on the force under the influence of which the car rolls down the slope of the slide, the strength of resistances of all kinds, on the reduced mass of the car with the load, taking into account the moment of inertia of the rotating parts. At the same time, the results of calculations proved that taking into account the mass of rotating parts practically does not affect the acceleration of the carriage along the slope of the slide. The acceleration formulas and the resulting forces acting on the car are presented in the generally accepted notation and in the usual sense, followed by the calculated data.
