A Study on Learning Pronunciation Strategies Used by English-Majored Students at the Ho Chi Minh City University of Food Industry
Authors: Hieu Pham Le
Published: September 2022

English pronunciation is very important for everybody. The English-majored students don’t have much time for English practice or improved pronunciation. So, this article is to find reality the best way to Learn English Pronunciation (LEP) for English-majored students with the hope of improving students’ pronunciation. In this research paper, the author will do a study on the learning of English pronunciation for English-majored HUFI college students. This article was made in many forms such as interviews, form collection, and data collection of more than 75 undergraduate English-majored students at the Ho Chi Minh City University of Food Industry. The research paper was conducted in April 2022. This research paper finds out that the student’s pronunciation reality is very weak. The student doesn’t have much time to practice and improve English pronunciation in college, and the way a teacher teaches English pronunciation is relevant to the student’s way and the difficulty of English pronunciation learning. This article finds out that, in teaching English pronunciation, the teacher may be uncomfortable with the student’s way of learning English. Based on the research paper find out, some of the best ways for teaching and learning English pronunciation for English-majored students.
Generalised Onsager Algebra in Quantum Lattice Models
Authors: Miao Yuan
Published: September 2022

The Onsager algebra is one of the cornerstones of exactly solvable models in statistical mechanics. Starting from the generalised Clifford algebra, we demonstrate its relations to the graph Temperley--Lieb algebra, and a generalisation of the Onsager algebra. We present a series of quantum lattice models as representations of the generalised Clifford algebra, possessing the structure of a special type of the generalised Onsager algebra [1]. The integrability of those models is presented, analogous to the free fermionic eight-vertex model. We also mention further extensions of the models and physical properties related to the generalised Onsager algebras, hinting at a general framework that includes families of quantum lattice models possessing the structure of the generalised Onsager algebras.

Authors: Vargas Ramirez Andrés Felipe , Ramírez Iliana María , Arroyave Andrés Felipe
Published: September 2022

Para asegurar un suelo adecuado para la agricultura, es muy importante medir el pH del suelo y la conductividad eléctrica (CE) del suelo, porque estas variables pueden usarse para predecir la disponibilidad de nutrientes para las plantas en el suelo. Por lo tanto, en este estudio se estudiaron el pH y la CE para un suelo ubicado en Santa Elena, un pueblo rural cerca de Medellín, Colombia. El pH del suelo se midió en el laboratorio mediante extracción con agua y soluciones de CaCl2, y también se midió en el campo. La CE del suelo se midió en el laboratorio utilizando extracción con agua. Los datos se usaron para trazar mapas de Variabilidad para pH y CE, y la regresión lineal de Deming se usó para encontrar las correlaciones entre las variables. Se encontró que el pH del suelo de la extracción de agua tenía una alta correlación con la CE del suelo

Bienal do Livro do Rio de Janeiro e conteúdo LGBTQ+: A limitação para representação visual de conteúdos inapropriados para crianças e adolescentes
Authors: Reis Ulisses Levy Silvério dos , Chaves Raíssa Lara Monteiro
Published: September 2022

O presente artigo tem como base problematizar qual seria a limitação para que determinado conteúdo fosse considerado impróprio para crianças e adolescentes, utilizando como base principal o caso ocorrido na Bienal do Livro do Rio de Janeiro, o Estatuto da Criança e do Adolescente e julgados correspondentes. O trabalho foi dividido em três tópicos, sendo utilizada análise jurisprudencial, bibliográfica e legislativa, além do método dedutivo. O primeiro tópico trata especificamente dos argumentos utilizados nas decisões relacionadas à Bienal e se livros com temática LGBTQ+ seriam considerados impróprios para o público infantojuvenil. Em seguida, analisa-se o Estatuto da Criança e do Adolescente, que explicita a proteção especial na tentativa de compreender o que é considerado conteúdo inapropriado, além das manifestações do Conselho Nacional dos Direitos da Criança e do Adolescente (Conanda) e do Conselho Nacional de Direitos Humanos (CNDH) sobre o mesmo assunto. No terceiro tópico examinam-se os julgados do Superior Tribunal de Justiça na tentativa de compreender qual o direcionamento da Corte com relação à limitação de conteúdo impróprio. Conclui-se que a limitação visual de conteúdos inapropriados para crianças e adolescentes caracteriza-se na apresentação de conteúdo pornográfico e obsceno, o que não é demonstrado nas manifestações de afeto de casais homoafetivos nas obras ameaçadas de retirada de circulação na Bienal.

A interdependência entre os elementos da “aplicação” e da “eficácia” das normas humanitárias à luz de uma perspectiva prática
Authors: Guerra Sidney Cesar Silva , De Sousa Sampaio Maiara
Published: September 2022

A pesquisa na área do Direito almeja demonstrar que, para se alcançar um real entendimento das normas humanitárias, é indispensável conjugar os elementos jurídicos da aplicação e eficácia. Com efeito, este trabalho pretende analisar as normas de Direito Internacional Humanitário, de modo a verificar situações fáticas que estão sob a incidência desse regramento, constituindo a análise das hipóteses de aplicação das regras humanitárias, um pressuposto para a investigação da eficácia desse conjunto normativo no âmbito internacional. Como resultado, esbarra-se na perquirição acerca das possíveis sanções em caso de inobservância ao regramento jurídico, do qual a possibilidade de responsabilização penal necessita compreender o conceito jurídico do ato tipificado como crime de guerra. Dentro dessa perspectiva, esta pesquisa utilizará como método científico o dedutivo, com perspectiva racionalista como a única forma de chegar ao conhecimento, recorrendo à cadeia de raciocínio descendente da análise geral para a particular por meio do emprego de silogismo.

ANTI-Trypanosoma cruzi PHENYLPROPANOIDS ISOLATED FROM Baccharis ligustrina C. DC. (ASTERACEAE). In the present work, dried aerial parts of Baccharis ligustrina (Asteraceae) were subjected to microwave assisted extraction (MAE) using aqueous solution of 1-butyl-3-methylimidazolium bromide (BMImBr) and the obtained extract was successively partitioned using hexane and EtOAc. Using reduced amounts of extracts and efficient chromatographic steps, four acyl C6C3 derivatives (n-hexacosyl ferulate, n-hexacosyl, n-octacosyl, and n-triacontyl p-coumarates) were obtained from hexane phase whereas two C6C3 acids (ferulic and p-coumaric) were obtained from EtOAc phase. Isolated phenylpropanoids were evaluated against amastigote forms of parasite Trypanosoma cruzi. As result, it was observed that p-coumaric and ferulic acids were inactives whereas alkyl derivatives displayed EC50 values of 6.5 µmol L-1 (n-octacosyl p-coumarate), 9.3 µmol L-1 (n-triacontyl p-coumarate), 15.7 µmol L-1 (n-hexacosyl p-coumarate), and 32.2 µmol L-1 (n-hexacosyl ferulate). All tested compounds displayed reduced toxicity against NCTC cells (CC50 > 200 mmol L-1).

THE POTENTIAL OF NATURAL XANTHONE α-MANGOSTIN IN THE DEVELOPMENT OF NOVEL ANTIINFECTIVE AGENTS: A REVIEW. The mangosteen (Garcinia mangostana, Linn.) is a tropical fruit cultivated in the tropical forests of Southeast Asian countries. It is recognized as the queen of fruits due to its unique color, aroma, and flavor. It has been used for centuries in Southeastern Asian traditional medicine for the treatment of various diseases. Many functional molecules with high medicinal value are obtained from the pericarp of mangosteen fruit, whose major constituent is xanthone α-mangostin. Several studies have been carried out over the last decades to further investigate and understand the pharmacological properties associated with the plant and its main chemical constituents, belonging to the class of xanthones. In addition, numerous in vitro and in vivo studies related to mangosteen have been published, indicating its importance and its potential application in medicinal chemistry. Prenylated xanthones, which include α-mangostin, are secondary metabolites particularly common in plants belonging to the Clusiaceae family. These substances have been intensively investigated for their potential as biologically active agents. This article describes a critical analysis of published data related to the properties of α-mangostin, aiming to provide a more detailed view of its potential as a chemotherapeutic agent for the prevention and treatment of infectious diseases.
Can the Risk Factors Predicting Surgical Treatment be Determined in Patients with Tubo-Ovarian Abscess?
Authors: Vural Tayfun , Bayraktar Burak , Yildirim Karaca Suna , Gurbuz Emir , Ozeren Mehmet , Taner Cuneyt Eftal
Published: September 2022

OBJECTIVES: In this study, we aimed to determine the risk factors in predicting the need for surgical treatment due to medical treatment failure in patients with tubo-ovarian abscess.
STUDY DESIGN: This is a retrospective cohort study performed in a university hospital between 2015 and 2020. Sixty-nine patients with tubo-ovarian abscess were treated with parenteral antibiotics. Some of them required surgery because antibiotic treatment was not successful. We compared the group in which parenteral antibiotic treatment was successful with the group that required surgical treatment. The conservative treatment group consisted of 43 (62.3%) patients who responded to antibiotic therapy alone (gentamicin-clindamycin), and the operation group consisted of 26 women (37.7%) who did not reply to antibiotic therapy and required operation. Demographic, clinical, sonographic, and laboratory results were compared between the two groups using univariate and logistic regression analyses.
RESULTS: Overall, up to 37.7% (26/69) of the patients underwent surgery after failure of antibiotic therapy. Patients who failed antibiotic therapy had higher infection parameters such as C-reactive protein (205±109 mg/dL vs. 115 ± 90 mg/dL, p=0.002), platelet count (349 ± 108 x 103/mm3 vs. 298 ± 95 x 103/mm3, p=0.042), and neutrophil-to-lymphocyte ratio (18.8 ± 35.7 vs. 8.2 ± 6.9, p=0.022). Also in the same group, larger tubo-ovarian abscess size (61.6±16.6 mm vs 45.8 ± 10.3 mm, p<0.001) and more frequent intrauterine device use (46.2% vs 16.3%, p=0.007) were observed. But none of them (C-reactive protein, neutrophil-to-lymphocyte ratio, tubo-ovarian abscess size, presence of an intrauterine device) was found to be a significant independent factor in anticipating conservative treatment failure of tubo-ovarian abscess in logistic regression analysis.
CONCLUSION: Although helpful in diagnosis, none of the demographic, sonographic, or laboratory parameters can predict surgical treatment in women with tubo-ovarian abscess.

The subject of the nature of the action for the benefit of the other’s deceit is a very controversial subject; Between them is an action for compensation or a restitution action, since it has very different practical effects. When it took a jurisprudential interest was in the Inverlink case, where the CORFO was forced to civilly sue all those investors (outside the Inverlink group) who withdrew their investments in advance, not knowing that the money with which they materialized these rescues were funds subtracted from CORFO. That is why it is important to review the importance of this action, its discussion on its legal nature, which  established the Supreme Court in its regard, and then finally analyze whether or not this action for the case AC Inversions, which explodedin March This year, similar in nature to the Inverlink case.
Medidas para proteger al socio frente a los abusos de la mayoría social
Authors:   Universidad de Sevilla, Sevilla, España, Viguera Revuelta Rodrigo
Published: September 2022

El artículo trata de recoger el complejo juego de equilibrios que tiene lugar entre el socio de control o, en su caso, el socio mayoritario, desde las prerrogativas que le concede el régimen de mayoría de las sociedades de capital, el interés social y el interés particular del socio minoritario. Para ello hemos partido de los clásicos instrumentos de protección con los que cuentan los socios minoritarios. Y, a continuación, hemos hecho un análisis de dos importantes novedades –tanto en el campo jurisprudencial (Sentencia del Tribunal Supremo de 23 de septiembre de 2014), como en el apartado legislativo (Ley 31/2014 por la que se modifica la Ley de Sociedades de Capital para la mejora del gobierno corporativo)– que no han hecho sino aumentar los mecanismos de protección con los que podrán contar, desde la fecha, los socios minoritarios.

Parkinson's Disease in Patients with Essential Tremor: A Prospective Clinical and Functional Neuroimaging Assessment
Authors: Froehner Gabriel Sampaio , Camargo Carlos Henrique Ferreira , Fabiani Giorgio , Meira Alex Tiburtino , Filho Raul Martins , Munhoz Renato Puppi , Teive Hélio Afonso Ghizoni
Published: September 2022

Introduction:

Patients with essential tremor (ET) have 3.5 times greater risk of developing Parkinson's disease (PD) throughout their lives, also known as PD with antecedent ET (ET-PD). Single photon emission computed tomography with radiotracer imaging of dopamine transporters (TRODAT-SPECT) can help differentiate these two diseases.

Method:

Relate the results of TRODAT-SPECT imaging in patients with ET to potential progress to ET-PD. Thirty-six patients with ET were evaluated by neurological examination, the Archimedes spiral, and the MDS-UPDRS III scale on two occasions, after a mean interval of three years. SPECT was performed on all patients after the first visit.

Results:

Overall, six patients (16.6%) progressed clinically to ET-PD. Patients with ET-PD were older, and the age of tremor onset was later. The ET-PD group scored higher on the MDS-UPDRS III scale, especially for the presence of bradykinesia. SPECT imaging was altered in 83.3% of the ET-PD patients compared to 33% of the ET patients (p=0.034). Changes on the SPECT with asymmetrical hypouptake suggested progress to ET-PD (p=0.025).

Conclusion:

Advanced age at the onset of tremor, the presence of bradykinesia, and asymmetrical alterations in SPECT may be related to progression to PD in patients with ET. Changes in neuroimaging suggest that SPECT-TRODAT can be used to predict progression to PD in selected patients.
Effect on Dental Stains by Potassium Tripolyphosphate Added Chewing Gum
Authors: Porciani Pier Francesco , Grandini Simone
Published: September 2022

Background:

Today, people worldwide consider the discoloration of teeth the main concern, therefore, dental stains are an important problem for a lot of patients, especially for smokers, and tea and coffee consumers.

Objective:

This trial was planned to evaluate the effectiveness of a sugar-free chewing gum added with potassium tripolyphosphate, compared to a placebo chewing gum on the development or the removal of dental extrinsic stains preserving regular daily oral hygiene.

Methods:

This was a single-center, double-blind, randomized, 6-week parallel controlled clinical trial. Among those who were eligible for the trial, 162 adult participants were randomly allocated into two groups of 81 each and were instructed to maintain customary oral hygiene. All subjects started the trial period after an in-office dental visit to set the stain index baseline. They chewed one of the two chewing gums for six weeks, five pieces per day, preferably after meals and snacks, for 10 minutes. Both chewing gums were sugar-free, 2g of weight with the same size and shape. The test chewing gum contained potassium tripolyphosphate (24.4 mg per piece), the control chewing gum was identical without potassium tripolyphosphate, therefore, it did not contain any anti-stain agent. The dental extrinsic stain was measured at the first visit and at the end of six weeks by the Modified Lobene Stain Index (MLSI). Comparisons between the groups were performed using ANOVA after adjustment of the baselines, and comparisons between initial and final indexes inside the groups were performed using paired t-tests.

Results:

After the 6 weeks, 154 subjects completed the trial, 77 in each group. The mean difference in stain composite index for all sites after six weeks was 0.04±0.07 in the control group and -0.03±0.07 in the test group. This difference was statistically significant after baseline adjustment (p<0.001). Moreover, the differences in stain indexes for both buccal or lingual-palatal sites showed a statistically significant difference (p<0.001) for those using the test chewing gum versus the control chewing gum.

Conclusion:

The overall findings of this clinical study suggest that the use of chewing gum containing potassium tripolyphosphate can reduce dental stains versus placebo chewing gum on frontal teeth after six weeks of maintaining regular oral hygiene with normal tooth brushing.

Authors: Zyoud Amr H. , Hamdan Khaldoun M. , Alkouri Osama A. , Al-Sutari Manal M. , Al-Tarifi Malek , Albqoor Maha Alkaid , Shaheen Abeer
Published: September 2022

Background:

Problem-solving and effective communication are essential skills for daily nursing duties. Despite several studies highlighting those concepts, few examined the relationship between these concepts among nursing students. This study aimed to investigate undergraduate nursing students' problem-solving and communication skills.

Methods:

A cross-sectional correlational design was used. A sizeable convenient sample of 489 undergraduate nursing students was recruited from six nursing schools in Jordan. Data were collected using an online self-administered survey. The Arabic version of the Problem-Solving Inventory and a translated version of the Communication Skills Attitude Scale were used. Descriptive statistics and multiple linear regression were used to analyze the data.

Results:

The sample included 64.4% females. The mean total score of the problem-solving scale was 96.63 (SD=16.99). Gender, considering self as an initiative person, and negative attitude toward communication were significant negative predictors, while positive attitude toward communication was a positive predictor of nursing students' problem-solving skills.

Implications:

Educational programs that improve nursing students' attitudes toward communication and mental health courses that focus on positive personality traits are needed to improve nursing students' problem-solving skills.

Conclusion:

The results indicated a moderate level of problem-solving skills, a high level of positive attitudes toward communication skills, and a low level of negative attitudes toward communication skills among undergraduate nursing students.
Non-Gynecologic Tumors and Fertility Melanoma
Authors: Romagnolo Cesare
Published: September 2022

Melanoma is diagnosed within a wide range of ages, beginning in the third
decade of life: it occurs slightly more commonly in women younger than 40, and
represents the second most frequently diagnosed malignant tumor in patients 15 to 29
years of age. The overall incidence of melanoma in pregnancy is about 0.14 to 0.28
cases per 1000 births, accounting for 8% of malignancies diagnosed during pregnancy;
although occurring extremely rarely; melanoma is one of the most common tumors
known to metastasize to the placenta and the fetus.
From the recent literature, we can conclude that chest radiography with radiation
protection and abdominal ultrasounds are safe; Computed Tomography (CT) with
intravenous contrast and positron emission tomography are generally contraindicating
because of emission of high dose of radiation; Magnetic Resonance (MR) is safer than
CT, but it is contraindicated during 1st trimester of pregnancy because it employs heart
tissues and exposes the fetus to excessive noise than can cause high-frequency hearing
loss in neonates.
There is no conclusive evidence that pregnancy significantly affects melanoma
aggressiveness in terms of increasing metastases incidence or lowering overall survival.
Two recent investigations have reported increased mortality in women with pregnancy.associated malignant melanoma. Some data suggest that increased mortality of the
melanoma patients with recent childbirth is mainly due to a stage-independent causal
pathway: the pregnancy-associated immune suppression may permit some melanomas
with high malignant potential to progress and come to clinical diagnosis in the short
term following childbirth. However, some other data analysis shows no difference in
tumour location and stage at diagnosis between women with PAMM and non-PAMM;
furthermore, no evidence of a worse prognosis was found in women given the
diagnosis of PAMM. Given these results, the authors conclude that counselling and
monitoring women with PAMM do not need to be different from those provided for
women with non-PPAMM. The main goals of melanoma treatment during pregnancy
are to cure the neoplasia and avoid complications for the fetus; irrespective of
pregnancy status, wide local excision around the melanoma site with margins
proportional to the microstage of the primary lesion, is the treatment oflocalized
melanomas. In more advanced cases (>4mm depth), adjuvant therapy with high dose interferon
must be considered; although interferon is safely administered in pregnant patients with
haematological malignancies, adjuvant therapy with high dose interferon has not been
studied in pregnancy associated melanoma and therefore is not routinely recommended.
Review on Water Purifications Techniques and Challenges
Authors: Belekar R. M. , Dhoble d S.J.
Published: September 2022

Nowadays, the whole world is facing water containment issues caused by
anthropogenic sources, including household waste, agricultural waste, and industrial
waste. There is a huge impact of wastewater on the environment; hence, the public
concern over it has been increased. This led researchers to be motivated and find
radical and cheap solutions to overcome this problem. Several conventional techniques,
including boiling, filtration, sedimentation, and chlorination, are used for wastewater
treatment; however, they have limited scope. Some other methods like coagulation,
flocculation, biological treatment, Fenton processes, advanced oxidation, membrane.based processes, ion exchange, electrochemical, adsorption, and UV-based processes
have been applied to remove pollutants, but there are still some limitations. This review
chapter sheds some light on these traditional and modern methods applied for water
treatment, along with their advantages and disadvantages. These methods have the
potential to remove pollutants from wastewater, such as natural organic matter, heavy
metals, inorganic metallic matter, disinfection byproducts, and microbial chemicals.
The potential threats and challenges of using water treatment methods for safe water

Published: September 2022

The existence of organic acids in aqueous waste continues to be an
important environmental concern because of the odor and toxicity they impart to water.
The photochemical degradation of benzoic acids (BA) and some of the substituted
benzoic acids (SBA), which act as environmental pollutants, are studied in the present
investigation using the Advanced Oxidation Processes (AOPs) and combinations of
different oxidants and UV irradiation (UV/H2O2
, UV/TiO2
, UV/ZnO, and Fe(III)-
oxalate complex). The photo-oxidative degradation of these pollutants was followed by
studying their concentration decay over the period of exposure to the UV-oxidant
combination. The degradation kinetics of substituted benzoic acids (SBA) is observed
to be dependent on the directory nature of the substituent groups, analyzed by the
Hammett constant (σ), where electron-withdrawing groups (EWGs) show positive
values and electron-donating groups (EDGs) account for its negative values. These
observations figured out the processes that can be efficiently used for the system. Thus,
this paper aims to examine parameters that affect the photocatalytic degradation of
substituted benzoic acids.

Forty streptomycetes were isolated from the soils of farms in Riyadh. Only three isolates (St-2, St-9, and St-25) exhibited cellulolytic-ligninolytic activity, with the St-9 isolate exhibiting the highest activity and identified as Streptomyces lazureus. The optimum environmental and nutritional conditions for maximum cellulolytic-ligninolytic activity were determined as fermentation batch of pH of 7.5, inoculum size of 200 µL of bacterial suspension, incubation period of 7 d, and incubation temperature of 30°C. In addition, the fermentation batch contained peptone and yeast extract as the best nitrogen and carbon sources, respectively. Cellulase and ligninase were purified via gel filtration column chromatography. The accumulated end-product of the fermentation process was glucose powder, which was subjected to a partial characterization process. The glucose powder appeared white, melted at 146°C, was highly soluble in water, slightly soluble in ethanol, and insoluble in ethyl ether. The glucose solution appeared clear without precipitates and had a low electric conductivity of 15 µS.cm-1.

Concrete is widely used as a building material throughout the world. However, its use in building structures is limited due to its low tensile strength. This problem can be partially solved using steel bars reinforcement, as well as using dispersed reinforcement with various types of fibers. The authors propose the simultaneous traditional reinforcement of a concrete structure with steel bars with additional dispersed reinforcement with natural coconut fibers, relatively cheap and widely available in many countries in Africa, Asia and Latin America. The purpose of this study is to analyze the effectiveness of the proposed solution by comparing the required amount of steel reinforcement (by weight) for a beam made of traditional concrete and a similar beam with additional dispersed reinforcement with coconut fibers. Deflections and cracking in beams were investigated. The analysis was carried out using Autodesk Robot Structural Analysis Professional 2022 software. The results showed that a beam additionally reinforced with coconut fiber requires 11% less steel reinforcement (by weight) compared to a similar beam made of traditional reinforced concrete. In addition, the coconut fiber reinforced beam experienced 6% less deflection and significantly less stress cracking compared to a simple concrete beam. These results proved that the approach proposed in the work noticeably improves the performance of reinforced concrete in the structure, and also makes it possible to obtain significant savings in reinforcing steel.

Published: September 2022

It was ascertained that investigations on classification of architectural styles for shells and shell structures are absent. Only one published paper is available where architectural styles with indication of dates of appearance of the styles and dates of attenuation of their application are presented and the names of their founders are given. Now, the interest for the design, analysis, and building of thin-walled shells and shell structures is rising. There are no countries without erected shell structures. Hence, it is necessary to make more exact the classification of these erections and the distribution of them into groups. An aim of this work is collection of information about all known architectural styles as applied to shells and shell structures, and grouping of them due to characteristic traits and indications. All architectural styles were divided into five groups, i.e. avant-gardism, art deco style, modernism, ecotech style, and the newest styles. A special scheme, where distribution of architectural styles on these groups is applied to the examined structures, is given. Mutual influence of styles was revealed and presence of architectural directions and style flows in several styles was shown. The conclusions presented in this paper can demand the future accurate definitions and developments because specialists do not have common views to the list of architectural styles and to their classifications.

The movements of a reinforced net are considered. Mesh systems are used in various areas of modern technology, aviation, fishing, and construction. In recent years, much attention has been drawn to the complete equations that describe the motion of a deformable thread. In accordance with the studied task, the reinforcement of the net is carried out by adding terms in the equations of motion. In the planar case, the static behavior of the structure is investigated, and equations of motion are derived that allow the study of motion. The problem of wave propagation in deformable filament systems, taking into account a significant deviation of the filament shape from the original rectilinear one, is mathematically very difficult, since the equations of motion are a system of nonlinear differential equations in partial derivatives. To solve the problem, the method of characteristics is used. As well the method of characteristics solves the problem of the propagation of unloading waves (in the case of a load, shock waves arise). Depending on the velocity distribution at the boundary, the distribution of the strain constant on the characteristics is determined. The results are constructed by numerical integration of the integrals of the characteristics found by the method. The solution using the characteristic equations shows the occurrence of traveling waves.

Red clover is the main perennial legume crop in the Northern region. The article presents the results of the competitive variety testing of accessions (2019 and 2021) on nutritional value and feed productivity. Amounts of crude protein, fat, fiber, sugar, ash elements and carotene were estimated in contrasting meteorological conditions. The research years had signifi differences in the sum of temperatures, precipitation accumulation and hydrothermal coeffi During regrowth-beginning of fl period of red clover, the hydrothermal coeffi was 2.2 in 2019, and 0.75 in 2021. The purpose of the research was to study the nutritional value and productivity of breeding samples of red clover and selection of promising ones for further breeding work. The prevailing role of weather conditions over the varietal features of samples was revealed. In the dry year 2021, the studied indicators of nutritional value (except phosphorus) were higher than in the wet year 2019. In terms of nutrient content, SD-326, K-17421, K-46524, K-44964, K-1939 were identifi signifi exceeding the standard or showing a result at the standard level for two or more chemical components. In terms of high nutritional value and protein yield, three samples reliably confirmed the excess over the standard on average for two years of testing: SD-326-1227 kg/ha (+ 130 kg/ha), K-17421-1308 kg/ha (+ 211 kg/ha), K-46524-1156 kg/ha (+ 59 kg/ha). The obtained results will be used in future creation of red clover cultivars with high nutritional properties and feed productivity.

Abstract. Recreational areas contribute considerably to the establishment of sustainable and comfortable urban environment. Green stands and soils of recreational areas provide important environmental functions and ecosystem services, their utilization depends on natural and anthropogenic factors distinguished by land-use history. For the case of the recreational areas of New Moscow, a comparative analysis of trees (n=1909) and soils (n=39, 0-10 cm layer) of the parks, established on former forested and fallow lands, was performed. It was shown that the species diversity was higher although the tree condition score was lower in the forest-parks, compared to the parks established on former fallow lands, which were generally characterized by a higher level of maintenance. Soils of these parks had a neutral pHH20 (7.20.8) and high content of organic matter (8.52.5 %), whereas the forest-parks soils were similar to the natural Retisols of the forest area with pHH20 6.40.2 and 5.10.2, organic matter content 5.90.2 и 3.50.2 %, respectively. Soils of the parks, established on the former fallow lands, had also a higher pollution level by particular heavy metals as well as considering the integral pollution index. Thus, a higher level of maintenance of the parks established on former fallow lands coincided with a higher anthropogenic pressure and ecosystem alteration. However, reorganization of forests into forestparks allowed partial preservation of the natural ecosystems. That is necessary to consider for planning the new urbanized areas in Moscow.

Authors: Bakaneva Anna A.
Published: September 2022

Seed germination and development of common oak ( Quercus robur L.) during the first year of growing under conditions of the Volga-Akhtuba floodplain, Astrakhan region, were studied in the research. Currently, the floodplain forests of the Astrakhan region are experiencing a very high load from the grazing of farm animals and wild tourism. Therefore, it is necessary to restore degraded forest phytocenoses to increase species diversity. The aim of the study was to study the effect of flooding duration on oak germination of in the soil and climatic conditions of the Volga-Akhtuba floodplain in the north of the Astrakhan region. Sowing seeds were carried out according to the Sukachev method (1961). According to the results of the three-year research (2019-2021), it was revealed: the germination of seeds (acorns) of common oak ( Quercus robur L.) averaged 31 % of the total sown seeds. In 2019 and 2021, germination of oak in non-flooded areas was 5 % higher compared to other variants of the experiment (short-term and long-term flooding), resulted from seed loss due to prolonged flooding. In 2020, as a result of short flooding period, germination had an insignificant difference in variants. The height of annual seedlings of common oak in the variant of prolonged flooding differed significantly (35 cm higher) from other variants.
