Published: March 2023

One of the efforts to increase sweet corn productivity is to suppress weed growth by using herbicides combined with organic matter. This study aimed at examining the effectiveness of the herbicide atrazine on weed growth, growth and yield of corn plants given different doses of organic C. The experimental design used was divided plot design with three main plots of organic fertilizer levels and six subplots of herbicides which were replicated thrice. The main plot factor was the C-organic content consisting of low (1.02%), medium (2.50%) and high (3.50%). The second factor was the dose of the herbicide atrazine, which consisted of six levels of treatment, namely, no herbicide, atrazine herbicide doses of 1, 1,4, 1,8, 2.2 and 2.6 kg/ha. The results showed that the combination of atrazine at a dose of 1.4-2.6 kg/ha with organic C content was effective in controlling Ageratum conyzoides, Panicum repens and Paspalum conjugatum weeds. Atrazine herbicide treatment at a dose of 2.2 kg/ha affected the length of the cob, the weight of the cob without the cob, the yield of plots and the yield per hectare.

Published: March 2023

The verification of reachability properties of fuzzy systems is usually based on the fuzzy Kripke structure or possibilistic Kripke structure. However, fuzzy Kripke structure or possibilistic Kripke structure is not enough to describe nondeterministic and concurrent fuzzy systems in real life. In this paper, firstly, we propose the generalized possibilistic decision process as the model of nondeterministic and concurrent fuzzy systems, and deduce the possibilities of sets of paths of the generalized possibilistic decision process relying on defining of schedulers. Then, we give fuzzy matrices calculation methods of the maximal possibilities and the minimal possibilities of eventual reachability, always reachability, constrained reachability, repeated reachability and persistent reachability. Finally, we propose a model checking approach to convert the verification of safety property into the analysis of reachabilities.
Case report: Pneumatosis in a neonate with thrombocytopenia absent radius syndrome
Authors: Brady S. , Leone T. , Kim F.
Published: March 2023

BACKGROUND: Thrombocytopenia absent radius (TAR) syndrome is a rare disease with an estimated prevalence of one in 200,000 live births. TAR is associated with cardiac and renal anomalies as well as gastrointestinal problems such as cow’s milk protein allergy (CMPA). Typically neonates with CMPA present with mild intolerance, with few reports in the literature of more severe intolerance resulting in pneumatosis. We present a case of a male infant with TAR syndrome who developed gastric and colonic pneumatosis intestinalis. CASE DESCRIPTION: An eight-day-old male infant born at 36 weeks gestation with a diagnosis of TAR, presented with bright red blood in his stool. At this time he was on full formula feeds. Given continued bright red blood within his stool, an abdominal radiograph was obtained which was consistent with colonic and gastric pneumatosis. A complete blood count (CBC) was notable for worsening thrombocytopenia, anemia and eosinophilia. Once enteral feeds were held there was rapid resolution of the radiographic findings and resolution of his bloody stool. He was ultimately diagnosed with a CMPA. CONCLUSION: Though there are reports of CMPA in patients with TAR, the severity of this patient’s presentation with both colonic and gastric pneumatosis is unique. Without the knowledge of the association of CMPA with TAR, this case could have been misdiagnosed and led to reintroduction of cow’s milk containing formula, resulting in further complications. This case highlights the importance of a timely diagnosis and severity of CMPA in this population.

Published: March 2023

BACKGROUND: The femoral neck system (FNS) has been considered as a novel strategy for femoral neck fracture. The diversity of internal fixation creates difficulties in choosing an effective option for Pauwels III type femoral neck fractures. Therefore, it is significant to investigate the biomechanical effects of FNS versus conventional approaches on bones. OBJECTIVE: To evaluate the biomechanical characteristics of FNS versus cannulated screws coupled with medial plate (CSS+MP) for the treatment of Pauwels III type femoral neck fractures. METHODS: Through three-dimensional computer software (Minics, Geomagic – Warp), the proximal femur model was rebuilt. Based on the present clinical characteristics, models of internal fixation were reconstructed in SolidWorks, including cannulated screws (CSS), medial plate (MP) and FNS. After parameter setting and meshing, boundary conditions and loads were set up for the final mechanical calculation in Ansys Software. Under identical experimental conditions, such as the same Pauwels angle and force loading, the peak values of displacement, shear stress and equivalent (von Mises) stress were recorded. RESULTS: This study showed that the displacement of the models was CSS, CSS+MP, and FNS in descending order of magnitude. The shear stress and equivalent stress of the models was CSS+MP, FNS, and CSS in descending order. The principal shear stress of CSS+MP was concentrated on the medial plate. The equivalent stress of FNS was more dispersed and distributed from the proximal main nail to the distal locking screw. CONCLUSION: CSS+MP and FNS exhibited better initial stability compared to CSS. However, the MP was subjected to more shear stress, which could increase the risk of internal fixation failure. Due to its unique design, FNS may be a good choice for the treatment of Pauwels III type femoral neck fractures.

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) is an accepted minimal invasive procedure for the management of complications of portal hypertension. OBJECTIVE: This study aims to investigate the value of the preemptive administration of morphine, when compared with on-demand morphine, during TIPS. METHODS: The present study was a randomized control trial. A total of 49 patients were selected to receive 10 mg of morphine either before the TIPS procedure (group B, n= 26), or on demand when needed during the TIPS procedure (group A, n= 23). The patient’s pain was scored using the visual analog scale (VAS) during the procedure. VAS, pain performance, HR, systolic pressure, diastolic pressure and SPO2 were recorded at four-time points: before the operation (T0), during the trans-hepatic puncture of the portal vein (T1), during the intrahepatic channel expansion (T2), and when the operation was finished (T3). The duration of the operation was also recorded. RESULTS: In group A, the proportion of severe pain at T1 was 4.3% (one case), two cases were combined with vagus reflex, and the proportion of severe pain at T2 was 65.2% (15 cases). No severe pain occurred in group B. The VAS score significantly decreased at T1, T2 and T3 in group B, when compared to group A (P< 0.05). HR, systolic pressure and diastolic pressure significantly decreased at T2 and T3 in group B, when compared to group A (P< 0.05). There was no significant difference between the two groups in terms of SPO2 (P> 0.05). CONCLUSION: Preemptive analgesia can effectively relieve severe pain during TIPS, improve patient comfort and compliance, ensure a routine procedure, and offer excellent safety, and is simple and effective.

Authors: Li Changzhong , Ma Ya
Published: March 2023

BACKGROUND: To effectively circumvent foetal structural abnormalities and serious newborn sequelae, antenatal ultrasound evaluation can support making an early diagnosis for potential prenatal management or the termination of pregnancy. OBJECTIVE: This study systematically evaluated a meta-analysis of different pregnancy outcomes in the diagnosis of isolated foetal renal parenchymal echogenicity (IHEK) by prenatal ultrasonography. METHODS: Two researchers conducted a literature search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The following databases were included in the search: China National Knowledge Infrastructure, Wanfang Medical Network, China Academic Journals Full-text Database, PubMed, Web Of Science and Springer Link; additional library websites were also included, and the search reviewed different pregnancies among patients with IHEK. The outcome indicators were the live birth rate, the incidence of polycystic renal dysplasia and the incidence of pregnancy termination/neonatal death. The meta-analysis was performed using the Stata/SE 12.0 software. RESULTS: A total of 14 studies were included in the meta-analysis (total sample content, 1,115 cases). The combined effect size of prenatal ultrasound diagnosis of pregnancy termination/neonatal mortality in patients with IHEK was 0.289 (confidence interval (CI) 95%; range, 0.102–0.397). The combined effect size of the live birth rate of pregnancy outcomes was 0.742 (CI 95%; range, 0.634–0.850. The combined effect size of the polycystic kidney dysplasia rate was 0.066 (CI 95%; range, 0.030–0.102). The heterogeneity of all three results was > 50%; accordingly, a random-effects model was used.

Authors: Feng Shengchun , Yang Chunyan , Wang Jun , Fan Xiaopeng , Ying Xiaowei
Published: March 2023

BACKGROUND: Due to the complexity and heterogeneity of hepatocellular carcinoma, the existing clinical staging criterias are insufficient to accurately reflect the tumor microenvironment and predict the prognosis of HCC patients. Aggrephagy, as a type of selective autophagy, is associated with various phenotypes of malignant tumors. OBJECTIVE: This study aimed to identify and validate a prognostic model based on aggrephagy-related LncRNAs to assess the prognosis and immunotherapeutic response of HCC patients. METHODS: Based on the TCGA-LIHC cohort, aggrephagy-related LncRNAs were identified. Univariate Cox regression analysis and lasso and multivariate Cox regression were used to construct a risk-scoring system based on eight ARLs. CIBERSORT, ssGSEA, and other algorithms were used to evaluate and present the immune landscape of tumor microenvironment. RESULTS: The high-risk group had a worse overall survival (OS) than the low-risk group. Patients in the high-risk group are more likely to benefit from immunotherapy because of their high infiltration level and high immune checkpoint expression. CONCLUSION: The ARLs signature is a powerful predictor of prognosis for HCC patients, and the nomogram based on this model can help clinicians accurately determine the prognosis of HCC patients and screen for specific subgroups of patients who are more sensitive to immunotherapy and chemotherapy.

Published: March 2023

BACKGROUND: Stress is one of the critical health factors that could be detected by Human Activity Recognition (HAR) which consists of physical and mental health. HAR can raise awareness of self-care and prevent critical situations. Recently, HAR used non-invasive wearable physiological sensors. Moreover, deep learning techniques are becoming a significant tool for analyzing health data. OBJECTIVE: In this paper, we propose a human lifelog monitoring model for stress behavior recognition based on deep learning, which analyses stress levels during activity. The proposed approach considers activity and physiological data for recognizing physical activity and stress levels. METHODS: To tackle these issues, we proposed a model that utilizes hand-crafted feature generation techniques compatible with a Bidirectional Long Short-Term Memory (Bi-LSTM) based method for physical activity and stress level recognition. We have used a dataset called WESAD, collected using wearable sensors for model evaluation. This dataset presented four levels of stress emotion, including baseline, amusement, stress, and meditation. RESULTS: The following results are from the hand-crafted feature approaches compatible with the bidirectional LSTM model. The proposed model achieves an accuracy of 95.6% and an F1-score of 96.6%. CONCLUSION: The proposed HAR model efficiently recognizes stress levels and contributes to maintaining physical and mental well-being.

Published: March 2023

Aging of the skin is a complex and multifactorial biological process, affected by different intrinsic and extrinsic factors. Exogenous factors affecting the process of skin aging, together with nutrition, are topics which currently draw considerable attention. Although it is difficult to accurately define what presents a healthy diet for maintenance of youthful skin, considering the evident lack of clinical data and studies in humans, there are numerous evidence suggesting that the food we eat affects our skin aging and its’ appearance. Well-documented is a fact that the modern diet is a large source of advanced glycation end products and reactive oxygen species – compounds formed during certain food preparation methods which accumulation is associated with different disease and recently, skin aging as well. This review gives the current state of knowledge related to the role which advanced glycation end products and reactive oxygen species, formed during the certain food preparation methods, have in the mechanisms of the premature/extrinsic skin aging. Additionally, it summarizes available information, in the form of recommendations for both the public and nutritional professionals who have an interest in this field, regarding food preparation methods and practices which prevent formation of aforementioned compounds in food and consequently could reduce the food contribution to premature skin aging.

Published: March 2023

With increasing environmental pollution and tendency to smoking, the number of patients suffering from chronic obstructive pulmonary disease is increasing and a demand for generic products for the treatment of chronic obstructive pulmonary disease (COPD) is growing. The long process of generic formulation development can be accelerated by using an inhaler with suitable fluid dynamics features. This paper presents a study of a newly patented single-dose Memmatec Mora® inhaler in two versions: with grid openings 1.0 (A) and 0.5 mm (B), using Seebri Breezhaler® as a reference product. The studies were conducted with inhalation powders containing 44μg glycopyrronium bromide placed in a capsule. The manuscript presents studies during the selection of a generic inhaler within the course of inhalation powder development by a pharmaceutical company. The fluid dynamics features of the inhalers and the dose delivered were determined. The aerodynamic particle size distribution (APSD) and the inhalable dose were tested using a cascade impactor. The delivery dose for the Breezhaler, Mora A and Mora B inhalers for a volumetric flow of 100 L×min-1 was 38.5, 40.5 40.3μg, respectively. Fine particle fraction of the inhalers tested was 22.3, 24.6 25.5μg, respectively. Results of the study indicate that increase of the glycopyrronium bromide inhalation dose can be achieved not only by changes in the manufacturing technology of inhalation powder, hard capsule technology or addition of best quality raw materials, but also by the use of a properly selected inhaler with specific fluid dynamics features.

Authors: Shixaliyev Kerem
Published: March 2023

The properties of mixtures and vulcanizates of polyvinyl chloride (PVC) and ethylene-propylene elastomers (SKEPT-40) with functional group polymers have been studied and it appears that the effectiveness of the application of functional group polymers (FQP) is characterized by the improvement of the complex properties of vulcanizates. As shown, among the FQP, the industrial scale production of PVC and the low cost of its use in the purchase of rubber mixtures based on Synthetic rubber ethylene propylene terpolymer (SREPT) have been developed. In this regard, new composition mixtures were obtained by replacing the main polymers in rubber mixtures with 5÷30 mass parts of PVC based on SREPT. The physical and mechanical properties of their technological and vulcanizates were studied. Experiments show that the sol-fraction and durability of vulcanizate in gasoline, gasoline-benzene (3:1) mixture, and meta xylol decrease with the increase of PVC content.

The decrease in the sol fraction of the vulcanizate can be explained by the low swelling of PVC in the above solvents. Therefore, a vulcanizate based on a PVC blend of synthetic rubber ethylene-propylene terpolymer has a higher oil and gasoline resistance than a vulcanizate based on unmodified EPDM. It became known that 10 wt. parts in SREPT. When PVC is included, the degree of swelling of the vulcanizate is reduced by 20% in gasoline, in the mixture of gasoline-benzene (3:1), M-xylene, and "Avtol" oil, compared to the vulcanizate based on SREPT 30 mass parts and when included, the degree of swelling of the vulcanizate decreases by 2.7 times in gasoline, 2.3 times in gasoline-benzene (3:1) mixture, and 3.2 times in "Avtol-10" oil.

A finite algebra A with discrete topology generates a topological quasivarietyconsisting of all topologically closed subalgebras of non-zero direct powers of A endowed withthe product topology. This topological quasivariety is standard if every Boolean topologicalalgebra with the algebraic reduct in Q(A) is profinite. In the article it is constructed the specificfinite modular lattice T that does not satisfy one of Tumanov’s conditions but quasivarietyQ(T) generated by this lattice is not finitely based. We investigate the topological quasivarietygenerated by the lattice T and prove that it is not standard.

Published: March 2023

The strength of the building structure after a fire is determined by the length of time the fire takes place and the cooling process used. According to several previous studies, it is said that the longer the concrete burns, the lower the quality of the concrete will be. This study aims to observe the compressive strength of concrete after the combustion process by cooling through experimental trials on 21 samples of cube model concrete. The concrete sample consisted of three samples of normal concrete and 18 samples of concrete that would be given combustion treatment and the quality of the design concrete was K250. Three samples of normal concrete were tested at the age of 14 days, then 18 samples were prepared for the combustion process with normal fire. A total of nine samples of concrete were treated with combustion for one hour, two hours and three hours with normal cooling in the open air as many as three samples each. Meanwhile, nine other concrete samples that had undergone combustion were given cooling treatment by sprinkling with water. The average compressive strength of concrete with a duration of one hour, two hours and three hours without water cooling respectively is 320.05 kg/cm2, 285.65 kg/cm2 and 235.21 kg/cm2, with the percentage of decrease in the quality of concrete to normal concrete respectively is 9%, 19%, and 33%. Meanwhile, the average compressive strength of concrete with water cooling for the same duration of combustion is 295.72 kg/cm2, 245.34 kg/cm2 and 210.17 kg/cm2, with the percentage of decrease in the quality of concrete to normal concrete respectively is 16%, 30%, and 40%. Based on the results of this study, the duration of combustion and the cooling treatment used can reduce the quality of concrete compared to normal concrete.

Загальноосвітні школи пропонують дітям різноманітні можливості для розвитку їхніх фізичних якостей на заняттях з фізичного виховання. Серед популярних наразі видів фізичної активності не останнє місце займають заняття пілонним спортом та повітряної акробатикою. Для застосування таких напрямків в школах потрібно дізнатися точку зору викладачів фахових дисциплін. Для цього ми вирішили провести анкетування серед викладачів з фізичного виховання України, щодо їхнього ставлення до додаткових занять у їхніх навчальних закладах цими напрямками. Отримані результати дають змогу визначити перешкоди та необхідні зміни у системі освіти задля того, щоб застосувати новітні підходи у фізичному вихованні. Тож, метою нашого дослідження є визначити відношення викладачів з фізичного виховання щодо застосування повітряної акробатики та пілонного спорту як варіативного сегменту у шкільну програму. Задля запровадження цих напрямків у фізичне виховання учнів молодшого шкільного віку на думку респондентів слід ввести додаткові дисципліни про підготовці викладачів з фізичного виховання, обладнати зали з відповідним професійним обладнанням та організувати факультативні заняття у школах для бажаючих займатися цими напрямками.

The purpose of the article is to analyze modern methods of influencing the subconscious of the audience in the telethon «Yedini Novyni».

Research methodology. To realize the purpose of the research, a comprehensive approach to the selection of the main research methods was used, namely: observation – for the analysis of the telethon «Edyny Novyni»; historical – for the study of phenomena in the process of their occurrence and in the dynamics of development; generalization and formulation of conclusions. And the implementation of the system approach helped to investigate in more detail modern methods of influencing the subconscious of the audience.

The results. It was determined that the modern information society is equated with the concept of «information war», which is characterized as a special form of influence on citizens from other countries in peacetime or wartime due to the dissemination of relevant information and the protection of citizens of one’s country from such influence. Due to the start of a full-scale war of Russia against Ukraine, which took place on February 24, 2022, the national telethon «Edyny Novyny» began its work with the aim of refuting Russian propaganda and fakes related to the situation in Ukraine.

After analyzing the structure of the national telethon, it was found out that it consists of informational teleplots with different topics: socio-political, military, economic, medical, cultural-historical, sports, scientific, logistical, etc. In addition, as part of our research, one of the issues of the national telethon was analyzed. And in accordance with the purpose of the research, modern methods of influencing the subconscious of the viewing audience of the telethon «Edyny Novyni» were considered.

Thus, the most common method of influencing the subconscious of the audience is capture, infection, information blockade, joining, word play, creation of information reality.

The scientific novelty of the article lies in the fact that, for the first time, an attempt was made to outline modern methods of influencing the subconscious of the audience in the telethon «Edyni Novyni».

Practical meaning. The results of the research can be used for the development of measures for the formation of information culture in the audience.

Key words: methods, mass media, subconsciousness, information war, telethon.
СОЦІАЛЬНОКОМУНІКАЦІЙНА КОНЦЕПЦІЯ ПРОПАГАНДИ ФАШИЗМУ С. ЧАХОТІНА: ПРОЄКЦІЯ НА «РАШИЗМ»
Authors: Bondarenko I.
Published: March 2023

The purpose of the article is the analysis and representation of the unexplored scientific heritage of S. Chakhotin, in particular, the concept of the psychological impact of political propaganda.

Research methodology. In the process of studying the model of the psychological impact of political propaganda, the methods of analysis and synthesis were applied – to mark and differentiate the basic concepts of the communication process; the Grounded theory methodology made it possible to collect and analyze factual material to determine the social and communication specifics of S. Chakhotin’s theory; the social engineering approach made it possible to determine the technological resource of communication technologies.

The results. S. Chakhotin distinguished two forms of political propaganda – «rational propaganda» or «scientific propaganda», based on the intelligent use of information resources, and «retroactive» or «violent» propaganda that uses the mechanism of total aggression. At the same time, the techniques of effective political propaganda in both the first and second cases are identical. The communication basis of this technology has a pyramidal structure: the basis is a philosophical teaching (for example, Marxism), the next concept is a political program, then a slogan, and the top of the pyramid is a graphic symbol. The researcher made interesting comments about the technology of promoting graphic symbols among the masses.

Novelty. The article presents an unexplored concept of the psychological impact of political propaganda on the masses of S. Chakhotin; theoretical aspects of teaching are superimposed on modes of Russian propaganda.

Practical importance. The results of the article can be used in the educational process of a higher school, as well as in the reconstruction of the historical foundations of the development of the science of social communications.

Key words: influence, masses, narrative, crowd, symbol, social engineering, propaganda, advertising.
