Simulated Transit Vibration and Silver Thiosulfate Applications Affect Ethylene Production and Leaf Abscission of Begonia and Schefflera
Authors: Auer Carol A. , McConnell D. B.
Published: September 2022

Vibrations of 0.02 gravitational force (g) at 4.1 cycles per second (cps) were applied to Begonia ‘Medora’ and Schefflera arboricola (Hayata) Merrill during 6 days of simulated transit. Vibration caused leaf abscission, necrotic leaf areas, and severed stem tips. Silver thiosulfate (STS), applied as a previbration foliar spray (0, 0.28, 0.56, 1.12, mM silver), increased leaf abscission of begonias but not scheffleras during simulated transit. Ethylene emanation from stem tips of both species increased as STS concentration increased. Ethylene emanation from stem tips was not affected by vibration. During 4 weeks of simulated retail holding, STS decreased begonia leaf abscission.
Abnormal Needle Morphology in Loblolly Pine Induced by Low Humidity
Authors: Seiler J. R. , Johnson J. D.
Published: September 2022

Abnormal needle tip curling was induced by low humidity in 4 half-sib families of loblolly pine (Pinus taeda L.) grown in a growth chamber. The injury developed on new growth on both 12-week-old and 1-year old seedlings when plants were maintained under 30% ± 5% relative humidity with a 16-hour photoperiod, 23°C light period and 17° dark period. Very little injury developed on plants maintained at 70% ±5% relative humidity. Significantly more needle tip curling occurred on seedlings grown from seed collected in Texas than in seed collected from Virginia.

Authors: Kiang C. K. , Zu-Zhao Jin
Published: September 2022

In Sichuan, China, 3 different types of Citrus ichangensis (Swingle) with mono-winged petioles and 1 type with tri-winged petioles have been found. Among 3 types with mono-winged petioles are an early-blooming type with white flowers, an intermediate-blooming type with purple flowers, and a late-blooming type with light purple flowers. The tri-winged petiole type is more cold-hardy than any other type of C. ichangensis growing in this area.
The Influence of Summer Pruning Current-season Shoots on Growth, Floral Bud Development, and Winter Injury of Mature Peach Trees
Authors: Rom Curt R. , Ferree David C.
Published: September 2022

Current season shoots of 5-year-old ‘Redhaven’ peach trees were pruned in half on 1 July, 1 Aug., or both dates (50, 80 days after growth shoot initiation). Pruning reduced current season shoot length compared to unpruned shoots, but only 1 July pruning reduced current season shoot diameter, and increased lateral shoot growth. All pruning treatments reduced flower bud number proportional to shoot length removed; however, 1 Aug. pruning increased flower bud density per node. The previous summer season pruning did not influence the amount of winter injury on 1-year-old shoots after exposure to severe winter temperatures (-27.8°C). Summer pruning did not influence number of new shoots formed the following spring.
Net Gas Exchange by Leaves of Intact and Excised Apple Shoots as Influenced by Vapor Pressure Gradient
Authors: Schaffer Bruce , Bubenheim David L. , Barden John A.
Published: September 2022

Net photosynthesis (Pn), transpiration (Tr), and stomatal conductance for CO2 (gs) were determined at 26° ± 1°C for leaves on intact and excised apple shoots at different vapor pressure gradients (VPG’s). Pn, Tr, and gs of leaves on intact and excised shoots responded similarly to changes in VPG. Pn and gs were not affected directly by VPG. Tr increased as VPG increased since stomatal closure did not counterbalance the increased VPG.

Published: September 2022

Inheritance of resistance to tomato yellow leaf curl virus (TYLCV) was studied in the interspecific crosses Lycopersicon escutentum Mill. cv. UC 82 x Lycopersicon cheesmanii ssp. minor (Hook) C.H. Mill. LA 1401, and Lycopersicon esculentum cv. VF 145-B-7879 x Lycopersicon hirsutum Humb. and Bonpl. LA 386. Genetic populations were artificially inoculated with TYLCV prior to transplanting, and were later evaluated under field conditions. Reaction of parents, F2 and F3 plants, and backcrosses of resistant F2 plants to UC 82, indicated that resistance derived from L. cheesmanii seems to be recessive. Narrow sense heritability (NSH) was 0.44. Reaction of parental F1, F2, and backcross plants indicated that resistance derived from L. hirsutum is dominant and controlled by more than one gene.

Laying the foundations of a more conscious society? How vendors, consumers and organizers socially construct farmers’ markets in Bogotá, Colombia
Authors: Gütschow Malin , Feola Giuseppe
Published: September 2022

This study examines how vendors, customers, and organizers socially construct agroecological farmers markets (FM) in Bogotá. Using a multi-method approach entailing structured and unstructured interviews, descriptive statistics, and ethnographic content analysis, the study shows how the actors situate FM in relation to debates on sustainability, rural development, and alternative agri-food systems in Colombia. The results demonstrate that vendors, customers, and organizers often hold largely similar perspectives on FM and their relations with the dominant food system. Specifically, they conceive of FM as an alternative to the dominant food system and experience them as spaces in which utilitarian relations are put aside in favour of alternative values and practices, which include care for other human and non-human beings and limited economic competition. Furthermore, FM simultaneously function as protective spaces for peasant knowledge and culture and connectors between rurality and urbanity. Finally, this study shows that FM cannot be fully understood within the sectoral scope of sustainable agriculture, or rural development; rather, they represent an attempt to lay the foundations of a more conscious society that vendors, customers, and organizers want to help come into being.

Metodología: se realizó una investigación cualitativa con enfoque fenomenológico hermenéutico que posibilitó acceder a los relatos de los participantes a través de siete entrevistas semiestructuradas con adolescentes y siete con padres. Los resultados muestran relatos sobre el riesgo en torno a la sexualidad y el consumo de sustancias psicoactivas en escenarios donde se relacionan con otros. Como conclusión se encuentra que hay una delgada línea entre la exploración y la práctica de riesgo y que los adolescentes, sujetos con capacidad de conciencia, pueden vivir las experiencias como una u otra de acuerdo con la presencia y el uso de los recursos con los que cuentan.
La seguridad psicológica del personal de salud durante la pandemia por COVID-19: aproximación epistemológica y sociológica
Authors: Gutiérrez Álvarez Ana Karina , Mayo Parra Israel
Published: September 2022

La pandemia de COVID-19 pone en evidencia la importancia de los aspectos psicológicos y de salud mental para la prevención y afrontamiento de sus consecuencias. En este contexto se requiere de un modelo de Seguridad Psicológica (SP) que fundamente teórica y metodológicamente su gestión en una situación de emergencia sanitaria. El problema de la SP, visto desde una perspectiva transdisciplinar, intercepta aspectos relacionados con la epistemología y la sociología de la ciencia: análisis crítico del concepto a la luz de los aportes de otras disciplinas; relaciones entre el nivel de acceso al conocimiento y el funcionamiento de los equipos de trabajos; y contradicción entre la gestión neoliberal de la pandemia y la necesidad de un afrontamiento humanista. El objetivo del artículo es analizar, desde la perspectiva sociológica y epistemológica, la SP del personal de la salud en emergencias sanitarias, para lo cual se desarrolló una revisión narrativa. Como resultado, se presentan las reflexiones desarrolladas acerca del tema estructuradas en dos momentos: la aproximación crítica a la epistemología del concepto de SP y el impacto de la SP en los equipos de trabajo visto desde la concepción de la sociedad del conocimiento. Se enfoca la SP como un campo transdisciplinario y se valoran los antecedentes y aportes de otras disciplinas para su empleo en situaciones de emergencia y desastres. También se contrasta el afrontamiento a la COVID-19 desde la gestión neoliberal con su afrontamiento humanista. Finalmente, se presenta una nueva perspectiva de la SP para la gestión de la salud mental del personal de la salud involucrado en la respuesta a emergencias y desastres.

Nature-based solutions for water management: insights to assess the contribution to urban resilience
Authors: Beceiro Paula , Brito Rita Salgado , Galvão Ana
Published: September 2022

Assessing the Nature-Based Solutions (NBS) contribution to urban resilience, along with developing tools capable of demonstrating their long-term value, comprises a most needed step forward. Nevertheless, the NBS contribution to urban resilience has been yet slightly explored. Given the urban resilience complexity and multiple NBS capabilities, specific needs for a robust assessment should be investigated. This paper identifies the requirements for a comprehensive assessment of the NBS contribution to urban resilience and analyses the main assessment frameworks focused on resilience and NBS for urban drainage. First, the evolution of the resilience concept and relevant resilience assessment frameworks (RAF) are presented. Secondly, NBS challenges to enhance resilience and NBS assessment proposals are analysed. Thirdly, the attributes for assessing urban resilience and aspects to assess the NBS contribution are analysed. To conclude, a critical analysis of the assessment approaches is presented. Important challenges across the RAF have been identified, especially regarding their feasibility of application. Based on the performed analysis, most RAFs are not feasible for city benchmarking and assessing the resilience evolution over time, neither for assessing comprehensively the NBS contribution. Regarding specifically the NBS assessment proposals, just one focused on urban resilience was developed to date, which allows evaluating their contribution over time, between cities, or between different NBS.

Published: September 2022

Este artículo da a conocer una investigación acerca de la percepción del gobierno electrónico como instrumento de gestión por parte de los exportadores de mezcal en Oaxaca (México). Se efectuó una investigación cualitativa de tipo exploratorio y transeccional. Para obtener la información se utilizó una entrevista semiestructurada, mediante un muestreo por conveniencia. Se encontró una percepción positiva del gobierno electrónico como instrumento para mejorar los procesos de exportación. Sin embargo, los exportadores perciben muy básicos y deficientes los servicios, lo que se aúna a la falta de conocimientos para el uso de estos. También se encontró que el gobierno electrónico como herramienta para fomentar la digitalización de diversos sectores económicos —como, en este caso, la gestión en los procesos de exportación de mezcal— será clave para el desarrollo, en particular cuando se diseñe a partir de las necesidades reales de los exportadores y se acompañe con capacitación al usuario. Se concluye que no se están aprovechando todos los beneficios del gobierno electrónico, lo cual ocasiona una pérdida de eficiencia y eficacia en la gestión de la exportación.
Patient-related Barriers to Effective Pain Management: A Cross-sectional Survey of Jordanian Nurses
Authors: Alzghoul Bashar I. , Al Humoud Shoug , Abdullah Nor Azimah Chew
Published: September 2022

Introduction:

Pain is a common symptom of many diseases and conditions. Most human systems, such as the cardiovascular system, gastrointestinal system, and immune system, are affected significantly due to the occurrence of this symptom. Therefore, pain management is an essential element in the treatment plan for patients, which continues to attract considerable attention of researchers and international health organizations.

Patient barriers to pain management, such as denying the prescribed analgesic and/or refusing to disclose pain, are potential causes of pain management deficiency. When it comes to pain management, nurses constitute the first line of the in-patient care system. They are responsible for identifying and verifying the need for pain management intervention in addition to delivering it based on the plan or suggesting modifications to the patient care plan. In addition to that, nurses are expected to identify the presence of any barrier that impacts the pain management plan.

Objective:

This study aims to explore the perceptions of Jordanian public hospitals’ nurses regarding the patient-related barriers in pain management.

Methods:

The cluster sampling method was used; 13 hospitals in the central province of Jordan were selected after being evaluated, and a questionnaire on patient-related barriers to pain management (16-items) was circulated to all nurses. 600 nurses were approached, and 307 (51%) responded to the questionnaire.

Results:

The questionnaires were analyzed using descriptive statistics. The study found the patient-related barriers to pain management to be low based on nurses’ prespectives (mean= 0.63; SD= 0.0268).

Conclusion:

Jordanian patients have a serious misconception regarding the side effects of analgesics. So, the Jordanian ministry of health and Jordanian hospitals should offer health education related to it.

option needs to be managed by an expert Gynecologic Oncologist within a multi-speciality oncologic team. This chapter reviews the clinical condition which may
influence the final decision, in particular: stage of disease, grade of differentiation, and
histologic subtype. Oncological outcomes and fertility outcomes are reported on the
basis of the currently available literature.
Fertility Issues in Hereditary Gynecological Malignancies
Authors: Del Pup Lino , A Peccatori Fedro
Published: September 2022

BRCA1 or two mutation carriers have an increased risk of developing breast
and ovarian cancer. Moreover, they may also have reduced oocyte reserve, occult
primary ovarian insufficiency, decreased fertility, poorer response to ovarian
stimulation and earlier age at menopause. Even if these associations are still
controversial, carriers should be properly informed in order to program motherhood
and fertility preservation when appropriate.
Women with Lynch syndrome (LS) have an increased risk of developing endometrial
cancer at an early age and a slightly increased risk of ovarian cancer. Thus, the
promotion of early parity with subsequent hormonal contraception or prophylactic
hysterectomy after completing childbearing should be discussed during counseling.
Analysis of Seasonal and Spatial Variations of Water Quality of Dulhara and Ved Ponds in Ratanpur, Chhattisgarh, India
Authors: Nayar Renu , Sharma G.D. , Kohale Ritesh , Dhoble S.J.
Published: September 2022

Pollution load, rising population, and scarcity of water have drawn special
attention for the management of water resources such as pond water. The present
investigation was carried out at Dulahra and Ved ponds in Ratanpur, Bilaspur District.
The seasonal deviations in water such as transparency, temperature, pH, dissolved
oxygen, nitrate, phosphate, biological oxygen demand (BOD), total dissolved solids
(TDS), and total suspended solids (TSS) were evaluated. In the contemporary study,
the BOD standards were considerably higher than World Health Organization (WHO)
standards (5 mg/l). The water samples were collected from each site at outer (about
100-150 meters) and internal (10 m from the shoreline) localities. The highest mean
value of BOD, i.e., 32±4.6, was found at the north peripheral S-1 in the summertime. In
the summer season, maximum mean BOD 39±2.1 was found at S-2 (West peripheral)
in Ved Pond. It indicates the biological pollution load on the water body in the site of
North peripheral in Dulhara pond and West peripheral in Ved Pond in the summer
season. Low Secchi depth readings such as 20±1.0 at S-2 North peripheral site during
summer seasons are indicative of reduced water clarity that is habitually related to the
existence of suspended particles and algal tinges. We also found the maximum value of
total suspended solids on the north side of the pond, where the transparency of water
was also very low. A transparency value of 37.0±0.40 was noted at S-1 in the East
marginal sites and 30±0.22 at the East inner sites in the rainy period at the Ved pond.
The transparency of the water physique is exaggerated by the elements like planktonic
growth, rainfall, the sun’s location in the sky, the angle of incidence of rays,
cloudiness, electiveness, and turbidity due to deferred inert particulate material. Our
outcomes suggest that the lowermost water transparency value was 16.0 ± 0.41 at S-1
in the North marginal sites for the duration of summer. The concentration of Calcium
ions was much above the WHO recommended value of 75 mg/l at almost all the sites
and both ponds during the study period. Numerous indicators and catalogues have been established in this particular study to evaluate water quality in intermediate water
bodies. For transparency studies,low-cost Secchi disk was used.
The Effect of Village Income and Gross Regional Domestic Product on Poverty in Indonesia
Authors: Aji Yore Isti Tosan
Published: September 2022

The problem of poverty still exists today, and economic disparities are still found in districts/cities in Indonesia. The government has taken various ways to alleviate the problem of poverty, one of which is by distributing village funds to all corners of the country. Based on the data availability in Buku Saku Dana Desa and Buku Pintar Dana Desa published by the Ministry of Finance, Village income from 2015 to 2017 tends to increase. Meanwhile, the number of poor individuals throughout Indonesia between 2016 and 2017 has decreased. This paper attempts to examine whether or not Village Income, such as Village Funds, Revenue Sharing Taxes and Levies, Village Fund Allocations, and Village Original Income, as well as the GRDP (Gross Regional Domestic Product), affect the incidence of District/City poverty in Indonesia. This study uses secondary data from Statistics Indonesia for two years, consisting of 407 districts/cities in Indonesia each year. The regression analysis with static panel data using a double log model is the data analysis technique used in this article. The results show that Village Income and GRDP have an effect on poverty in districts/cities in Indonesia, with values of -0.0004 for Village Funds, 0.003 for Revenue Sharing Taxes and Levies, -0.026 for Village Fund Allocation, 0.002 for Village Original Income, and -0.197 for Gross Regional Domestic Product. We advise the government to increase village fund transfers, village fund allocation, and GRDP to lower poverty levels.
On the Current Connection and Relation Between Health Informatics and Social Informatics
Authors: Smutny Zdenek , Vehovar Vasja
Published: September 2022

Scholars from the health and medical sciences have recently proposed the term social informatics (SI) as a new scientific subfield of health informatics (HI). However, SI is not a new academic concept; in fact, it has been continuously used in the social sciences and informatics since the 1970s. Although the dominant understanding of SI was established in the 1990s in the United States, a rich international perspective on SI has existed since the 1970s in other regions of the world. When that perspective is considered, the fields of understanding can be structured into 7 SI schools of thought. Against that conceptual background, this paper contributes to the discussion on the relationship between SI and HI, outlining possible perspectives of SI that are associated with health, medical, and clinical aspects. This paper argues against the multiplication and inconsistent appearance of the term SI when newly used in health and medical sciences. A more explicit name for the area that uses health and social data to advance individual and population health might be helpful to overcome this issue; giving an identity to this new field would help it to be understood more precisely and bring greater separation. This labeling could be fruitful for further segmentation of HI, which is rapidly expanding.

Published: September 2022

Background:
Rapid economic reviews efficiently summarize economic evidence. However, reporting main findings without assessing quality and credibility can be misleading. The objective of this study was to develop a rapid cross-validation screening tool to evaluate economic evidence when conducting rapid economic literature reviews.
Methods:
This article outlines our reasoning and the theoretical concepts for developing the screening tool.
Results:
This cross-validation tool is a qualitative approach under a Bayesian framework that uses prior health economic evidence to gauge the credibility of the rapid economic review's findings. This article describes an application of this tool and highlights practical considerations for its development and deployment.
Conclusion:
This tool can provide a valuable screening instrument to evaluate the quality and credibility of the economic evidence.

Published: September 2022

Antibiotic resistance is a major risk to human health worldwide due to antibiotic- and multidrug-resistant bacteria, especially in the case of serious infections, which limits the availability of antimicrobial treatment options. Focusing on the bacterial resistance mechanisms against antibiotics and the conventional strategies used to combat antimicrobial resistance, this review highlights the history of antibiotics and their target mechanisms, mentions the strategy limitations, provides the most recent novel alternative therapies to combat resistance, and illustrates their mode of action and applications that may treat several infectious diseases caused by bacterial resistance. Finally, this paper mentions future prospects that we believe would make a considerable difference in the microbial resistance battle. Novel antibiotic alternative therapies, including nanomaterial therapy, antimicrobial photodynamic therapy, hybrid antimicrobial therapy, and phage therapy, are covered in this review.
Critical Study on Vital Factors Influencing Productivity Improvement

Published: September 2022

Abstract: In the press moulding process, the challenging task is to increase the productivity cycle of the product with zero rejection. Major problems involved in this process are the consumption of time and deduction of temperature for the loading and unloading process of the material in the mould plate. It is recommended to preheat the mould plate to a certain limit so that the temperature needed while processing is obtained in a shorter span of time. To overcome the time consumption problem, the mould plate should be mounted in a shorter interval of time todecrease the raw material loading time process. In this case, it helps to uplift the productiveness and leads us to a zero rejection rate

Prospective teachers’ design of numeracy tasks using a physical distancing context
Authors: Kohar Ahmad Wachidul , Rahaju Endah Budi , Rohim Abdur
Published: September 2022

Physical distancing, which is widely practiced limiting the spread of COVID-19, is recognized to contain mathematical thoughts that can be harnessed as a context for prospective teachers’ practices of mathematical problem posing. The goal of this study is to investigate the profile of mathematical tasks posed by prospective mathematics teachers using the context of physical distancing that meets the criteria of numeracy tasks. Data were collected from 66 mathematical tasks posed by thirty-three prospective teachers at a public university in Surabaya, Indonesia, attending an assessment course of numeracy based on a problem-posing task. To analyze, the posed tasks were first identified as solvable or unsolvable tasks and then further categorized into the domains of the level of context use and the level of cognitive processes. Results show that the level of context use embedded in the posed tasks varies from zero to first order, with only a few of the posed tasks being coded as having second-order context. Regarding the levels of cognitive processes, most of the posed tasks reach the level of understanding, with only a small number of reasoning tasks identified. Interestingly, all the tasks coded to contain second-order context are classified as reasoning tasks. Some implications regarding designing numeracy tasks using physical distancing and interventions in teacher education related to numeracy task design are discussed.

Authors: Suryanti Sri , Nusantara Toto , Parta I Nengah , Irawati Santi
Published: September 2022

Research on mathematics teacher professional development has emphasized primarily teaching quality enhancement. Mathematics task as one of the vital components in mathematics teacher education has been sparsely investigated. The purpose of this research is to explore mathematics teachers’ beliefs and practices in applying a problem-based task after attending one-semester online teacher professional training funded by the Ministry of Education. This is a mixed-method research design with data collected by distributing questionnaires to 105 mathematics teachers from 24 provinces in Indonesia after accomplishing an online professional training program to determine their self-reported beliefs about mathematical problem-based tasks. Data were also collected by conducting focus group interviews with 15 mathematics teachers with different teaching experiences. Teachers' relevant documents, such as course contents, task forms, and notes, were analyzed and used to enrich the qualitative interpretation. The quantitative result indicated that mathematics teachers' beliefs on the problem-based task were low. Meanwhile, the qualitative findings indicated this category of teachers constructed their problem-based tasks with no theoretical framework. Three misconceptions in designing problem-based tasks were also reported. Therefore, future research is recommended for a more acceptable and applicable problem-based tasks framework and design a specific teacher professional development training to promote teachers’ competencies.

Many students do not experience usefulness in mathematics. To address this problem, we offered them a mathematical tool, Sankey diagrams, which is a flow chart appearing in news media to visualize social, industrial or environmental processes. We carried out an Educational Design Research (EDR) to develop and evaluate lesson materials about contextualized Sankey diagrams. We tested these materials with a class of grade 8 students and evaluated these on the feasibility of students’ appropriation of the diagrams. In the lesson, we observed how students were able to read the Sankey diagrams, liked the societal processes visualized, yet did not fully grasp their mathematical properties. However, weeks later, the same students skillfully used Sankey diagrams in an unrelated project, which showed they needed time for their learning. Our contributions are that (1) grade 8 students can appropriate Sankey diagrams and use these in situations relevant to them, (2) design researchers should consider long-term learning effects beyond the experimental phase in EDR. We recommend educational designers to innovate curricula and introduce diagrams from news media to make students experience usefulness in school content.

Authors: Erbilgin Evrim , Macur Gregory Michael Adam
Published: September 2022

Solving arithmetic word problems has been a challenge for primary students due to difficulties in understanding the problem structure and relating the quantities in the problem to each other. This paper reports on an action research study to enhance students’ subtraction word problem-solving skills. The authors observed that their students had difficulties in representing the situations in word problems and solving the problems correctly. They designed, implemented, and analyzed an intervention to scaffold their students’ subtraction word problem-solving skills. As part of the intervention, a digital subtraction game was developed and used with second and third-grade students. The game involves three different representations: a discrete visual model, a bar model, and a number sentence. The students played the game and solved additional problems to strengthen their skills for representing and solving subtraction word problems. Twenty-four 2nd grade students in China and two 3rd grade students in Turkey participated in the study. Data sources included a pre-test, a post-test, student worksheets, and teachers’ filed notes. Data analysis showed an increase in students’ subtraction word problem-solving performance. They also effectively used a variety of representations to represent problem situations. The design and implementation processes of the intervention are discussed in the paper. We share suggestions for future implementation.

Based on the unpredictable effect of context familiarity when students solve real-world problems, this work aims to analyse how certain contexts can be used by pre-service mathematics teachers in the representation and real-world verification of a first-order mathematical model in the classroom in the subject of Ordinary Differential Equations. Specifically, this paper reports a classroom experience in which pre-service mathematics teachers compared the solution of a first-order ordinary differential equations (ODE) with a real-world experimental model. Using documentary records (i.e., students´ hand-written solutions and field notes) and a questionnaire on students´ perceptions on this classroom experience, qualitative results indicated that the pre-service mathematics teachers’ familiarity with an authentic context was a fundamental factor they chose a real-world model to represent the solution of a first-order ODE. Our analysis of the results highlights the importance of integrating familiar real-world contexts for pre-service mathematics teachers to model a first-order ODE, which is one of the fundamental principles of STEM disciplines.
Worked-examples instruction versus Van Hiele teaching phases: A demonstration of students’ procedural and conceptual understanding
Authors: Adeniji Saidat Morenike , Baker Penelope
Published: September 2022

This study explores the worked-example instruction (WEI) and the van Hiele teaching phases (VHTP) pedagogies to advance students’ acquisition of procedural and conceptual understanding of solving simultaneous equations. The quasi-experimental study involved two groups of high school students (age=15): 157 students in total with 72 in one group and 85 in the other. The study followed a pre-, post- and delay tests design. This study adapted two conceptual frameworks, the structure of the observed learning outcomes (SOLO) model and the Rasch model, and employed Rasch analysis and Statistical Package for Social Sciences (SPSS) as data analysis tools. The results indicated that both WEI and VHTP improved students’ procedural and conceptual understanding of solving simultaneous equations at the post-test; however, the WEI effects (on both procedural and conceptual understanding) were not sustained after the post-test while the VHTP had a lasting effect on only conceptual understanding. Furthermore, the VHTP group significantly outperformed the WEI group at the post-test and delay test in both conceptual and procedural understanding. These results indicated that the WEI is only beneficial at the initial stage of knowledge acquisition and VHTP is better at the initial and long-term. Practical implications of these results were discussed.

The usage of traditional approximating functions directly to the desired displacement vector of the internal point of a finite element to determine it through nodal unknowns in the form of displacement vectors and their derivatives is described. To analyze the stress state of a geometrically non-linearly deformable shell of rotation at the loading step, the developed algorithm for forming the stiffness matrix of a hexagonal finite element with nodal values in the form of displacement increments and their derivatives was used. To obtain the desired approximating expressions, the traditional interpolation theory is used, which, when calculated in a curved coordinate system, is applied to the displacement vector of the internal point of a finite element for its approximation of class C(1) through nodal displacement vectors and their derivatives. For the coordinate transformation, expressions of the bases of nodal points are obtained in terms of the basis vectors of the inner point of the finite element. After the coordinate transformations, approximating expressions of class C(1) are found for the components of the displacement vector of the internal point of the finite element, leading in a curved coordinate system to implicitly account for the displacement of the finite element as a rigid whole. Using calculation examples, the results of the developed method of approximation of the required values of the FEM with significant displacements of the structure as an absolute solid are obtained.
Promising cultivars of winter triticale for grain production in the north-west of the Astrakhan region
Authors: Fedorova Valentina A.
Published: September 2022

Triticale, due to its specific properties to form stable grain yields in the zones with risky agriculture, should find wider application in acutely arid conditions. Therefore, the use of highly productive cultivars of winter triticale in semi-desert zone of the north-west of the Astrakhan region is relevant. The aim of the research was a comprehensive assessment of promising winter triticale cultivars of different ecological and geographical origin for adaptability to stressful meteorological factors in semi-desert zone of the northwestern Astrakhan region. To determine the main indicators of adaptability (winter hardiness, plasticity, stability, stress tolerance, genetic flexibility), six promising winter triticale cultivars (Tribun, Interes, PRAG 152, Khleborob, Zhnets and Uragan) were studied. Field agroecological tests were conducted on rainfed fields of Precaspian Agrarian Federal Scientific Center of the RAS with different moisture level in 2018-2020. Nelli cultivar was used as a control. The methods of Selyaninov G.T., Zhivotkov L.A., Eberhart S.A., and Rassell W.A. were used for calculations. During periods of active vegetation of winter triticale, Selyaninov hydrothermal coefficient varied from 0.3 to 0.5 (zone of strong and very strong drought); environment index was from -0.67 to 0.66. According to the data obtained, cv. Khleborob showed the greatest adaptive potential and consistently high yield under various meteorological conditions of the season compared to the other tested winter triticale varieties. Moreover, the cultivar had good winter hardiness (5 points) and survival (90.8 %). On the average for the years of research it showed high adaptability coefficient (1.43), and the indicators of its plasticity and genetic flexibility were 0.77 and 1.40, respectively. Therefore, cv. Khleborob can be recommended for use in the acutely arid conditions in semi-desert zone of the northwestern part of the Astrakhan region.

To improve the efficiency of ruminal digestion, researchers have developed a variety of enzyme feed additives. We are also working to find feed additives that improve the nutrition of rumen microflora, that is, prebiotics. For this purpose, we have proposed an animal protein hydrolyzate. The paper presents data reflecting the dynamics of hematological and biochemical parameters of blood serum of calves at the age of 3-4 months when hydrolyzed mink carcasses are included in the diet at doses of 5, 10 and 20 grams per head per day for 30 days. It was shown that after the completion of the experiment in animals treated with hydrolyzate at doses of 10 and 20 grams per head, there was a significant decrease in the content of leukocytes within the reference values and an increase in the percentage of lymphocytes in the leukogram. The change in the biochemical parameters of the groups of experimental bulls was characterized by a dose-dependent statistically significant increase in the concentration of protein, urea and reserve alkalinity. The concentration of total bilirubin, ALT, LDH significantly decreased, AST- increased. The results obtained indicate an increase in the immune reactivity of the animal organism with the use of the feed additive.
