Published: July 2020

Deaths among children and pets, as well as damage to car interior components, have been widely reported as a result of parking under direct sunlight for a long time. Rising car cabin temperatures in this condition trigger the formation of benzene gas, but it is not possible to turn on the AC due to security and energy consumption. Therefore, this article reports the experimental study on cabin cooling system for parked car under direct sunlight by applying a mini air cooler and exhaust fan powered by a solar cell on small car Bajaj Qute RE60. Two thermocouples were installed inside and outside the cabin to monitor the temperature for 7 hours, expressing daytime heat conditions. The results showed that this cooling system could reduce the temperature to 10 K by removing 8982 kJ (0.356 kW) of heat. In conclusion, this prototype is very promising to be developed and if implemented on a larger scale will reduce car interior damage while parking under direct sunlight.

Authors: Adhikary Ramesh Prasad
Published: July 2020

Teaching grammar is one of the aspects of language teaching. From the past, different methods, like teaching from rules, teaching from examples, teaching through texts have been used to teach grammar in Nepal. So, this research was prepared to study the teachers’ assumption for teaching English grammar at lower secondary level in Nepal. The issue of teaching prepositions, articles, tense, tags, causative verbs and subject verb agreement are raised in this research. In this research, both the primary and secondary sources of data were used. Questionnaires were used to collect the data for the research. The result shows that most of the teachers use inductive ways to teach grammar lessons or they used student-centered techniques. It also concludes that the level of the learners, context and nature of the text also make the teachers to select the method for teaching.

Hydrogen Peroxide Production in an Electrochemical Flow-by Reactor using Gas Diffusion Electrodes Modified with Organic Redox Catalysts
Authors: Forti Juliane , Matulovic Mariana , Mollo Neto Mario , Santos Felipe , Lanza Marcos , Bertazzoli Rodnei
Published: July 2020

This paper presents a proposal to use an electrochemical flow-by reactor for hydrogen peroxide electrogeneration using cathodes formed from the incorporation of organic redox catalysts (2-ethylanthraquinone, 2-tert-butylanthraquinone, alizarin, and azobenzene) in the structure of gas diffusion electrodes. These electrodes help circumvent the low solubility of oxygen in aqueous solutions. Organic redox catalysts, which typically contain quinone or azo groups in their structure, were added to the electrode mass in a 10% proportion. The electrodes were used to study the electrogeneration of hydrogen peroxide in situ, in an acid medium (0.1 mol L-1 H2SO4 and 0.1 mol L-1 K2SO4, pH 1), inside an electrochemical flow-by reactor. Comparative analysis among the different catalysts indicated that the best electrode for hydrogen peroxide electrogeneration was the gas diffusion electrode modified with 10% of 2-ethylanthraquinone. With an underflow rate of 200 L h-1, hydrogen peroxide was formed with a maximum yield of 998.12 mg L-1 after 2 h at -2.0 V vs Pt//Ag/AgCl, for which the energy consumption was 11.21 kWh kg-1. The use of the electrochemical flow-by reactor was much more efficient, in that it yielded higher concentrations of hydrogen peroxide with extremely low energy consumption, compared to that obtained when using an electrochemical cell. In addition, for ensuring appropriate usage of the electrodes, optimizing their potential for the maximum generation of hydrogen peroxide, and obtaining the highest efficiency for the reduction of oxygen, a fuzzy algorithm was developed to help support the user’s decision.

Canonical correlations analyzes are being used in the agrarian sciences and constitute an important tool in the interpretation of results. This analysis is performed by complicated mathematical equations and it is only possible to use it thanks to the development of computational software, which allow different interpretations of results, and it is up to the researcher to choose according to his knowledge. Canonical correlations can be interpreted using canonical weights, canonical loadings, or canonical cross-loadings. In Brazil, most of the works that use these analyzes interpret the canonical weights. Therefore, this study aims to show, through an analysis of canonical correlations, the best way to interpret the results, so that they are presented in the most reliable way possible. Data from an experiment with two cultivars of biquinho pepper seeded in 5 light spectrums were performed. The variables were root length and volume, plant height, number of leaves, fresh shoot and root mass, shoot dry mass. Two groups of variables were organized, the multicollinearity was determined through the condition number and the inflation factor of the variance. Canonical correlations analysis was carried out, and weights, loadings, and canonical cross-loadings were estimated for the interpretation of the results. After the interpretations, it was defined that the canonical cross-loadings should be preferred for the interpretation of the canonical correlations. Weights or canonical coefficients provide dubious results of relationships between groups of characters and should be avoided.

Published: July 2020

Introduction:The Amazonas' State University provides Nursing, Medicine, Dentistry, and Pharmacy degrees with the experience of Rural Training in Public Health. Two MD students had high expectations of experiencing health care in the Amazonas interior, as they realized that there was a lapse in their academic training. They questioned the fact that they were about to take the place of "doctors trained by the state of Amazonas" without knowing the population, ethnocultural and geographical variety of the region. This lack encouraged the choice of the location of the internship to be the city of São Gabriel da Cachoeira. Methods:Meetings and lectures were held with health teams that enabled clinical experiences and interactions with indigenous and riverside residents. Finally, seminars/activity reports were produced, which contributed to the awakening of reflections on medical practices. Thus, this experience report is based on the particular apprehension of the reality described, based on daily observation. Results and Discussions: During the internship, the students began to question and deconstruct the doctor-user relationship hierarchy. Conclusions: Thus, they re-signified their practices beyond technical and biological knowledge, in line with the decolonial epistemology.
The Hemorrhaging Woman and Jairus’ Daughter as Representatives of Israel
Authors: Kubiś Adam
Published: July 2020

The scope of the present study is the symbolic analysis of the two interwoven Markan narratives about the healing of the woman with the flow of blood (5:25-34) and the raising of Jairus’ daughter (5:21-24.35-43). The principal thesis of this work consists in interpreting both women as symbols of Israel. The study begins with the presentation of the methodological premises of symbolic analysis. The main methodological premise of this work is the conviction that the literary sense of this pericope is in fact imbued with symbolism. Then there is a presentation of three criteria which help in detecting symbols in the biblical text: textual probability, conventions probability and contextual probability. Subsequently, in order to lend credence to the principal thesis of the article, seventeen literary elements found in Mark 5:21-43 are discussed; each of them meets the first two criteria and lends itself to symbolic interpretation of the two women as representations of Israel. The cumulative weight of these seventeen elements creates a rather strong cumulative argument in favor of the main thesis. Finally, the conformity between the symbolic interpretation of these women and both the immediate and global contexts of this pericope is discussed. The presence of this conformity meets the third criterion of contextual probability. The article thus offers a convincing case for the symbolic interpretation of the hemorrhaging woman and Jairus’ daughter in Mark 5:21-43 as representations of Israel.

Serum Matrix metalloproteinase-9 (MMP-9) can help identify patients with papillary thyroid cancer at high risk of persistent disease: Value and limitations of a potential marker of neoplasia
Authors: Dobrescu Ruxandra , Picu Catalina , Caragheorgheopol Andra , Manda Dana , Ioachim Dumitru , Goldstein Andrei , Badiu Corin
Published: July 2020

BACKGROUND: Matrix metalloproteinase-9 (MMP-9) is an important mediator of invasion and metastasis in neoplasia. In thyroid cancer expression levels correlate with aggressiveness but data on peripheral MMP-9 levels are less definitive. OBJECTIVE: Prospective study evaluating serum MMP-9 in the diagnosis and prognosis of papillary thyroid cancer. METHODS: Serum samples of MMP-9 were drawn before surgery in 185 consecutively enrolled patients with nodular thyroid disease, stratified on pathology as benign disease (N= 88) and papillary thyroid cancer (N= 97). Serum MMP-9 was measured by an immunometric assay. RESULTS: MMP-9 levels were not different between benign vs malignant pathology (p= 0.3). In papillary thyroid cancer there was no significant difference in MMP-9 levels between histologies, TNM stage and invasive/non-invasive cancers. High-risk patients with multiple features of aggressiveness had significantly higher MMP-9 levels compared to low-intermediate risk patients (767.5 ± 269.2 ng/ml vs 563.7 ± 228.4 ng/ml, p= 0.019). A cut-off of 806 ng/ml distinguished high from low-intermediate risk patients with a sensitivity of 60% and a specificity of 87.36%, p= 0.018. In patients with available follow-up data (N= 78), MMP-9 was higher in patients who required ⩾ 2 doses of 131I therapy (p= 0.009) and in those with biochemical evidence of persistent disease/who required additional therapy to achieve disease-free status (p= 0.017). CONCLUSION: Serum MMP-9 is not useful in the diagnosis of PTC, but preliminary data shows that high pre-surgical serum MMP-9 levels may identify patients at higher risk of persistent disease who require intensive treatment. Large volume prospective studies are required to confirm this observation.

Published: July 2020

BACKGROUND: Patients with oral squamous carcinoma (OSCC) present difficulty in precise diagnosis and poor prognosis. OBJECTIVE: We aimed to identify the diagnostic and prognostic indicators in OSCC and provide basis for molecular mechanism investigation of OSCC. METHODS: We collected sequencing data and clinical data from TCGA database and screened the differentially expressed mRNAs (DEmRNAs) and lncRNAs (DElncRNAs) in OSCC. Machine learning and modeling were performed to identify the optimal diagnostic markers. In order to determine lncRNAs with prognostic value, survival analysis was performed through combing the expression profiles with the clinical data. Finally, co-expressed DEmRNAs of lncRNAs were identified by interacted network construction and functional annotated by GO and KEGG analysis. RESULTS: A total of 1114 (345 up- and 769 down-regulated) DEmRNAs and 156 (86 up- and 70 down-regulated) DElncRNAs were obtained in OSCC. Following the machine learning and modeling, 15 lncRNAs were identified to be the optimal diagnostic indicators of OSCC. Among them, FOXD2.AS1 was significantly associated with survival rate of patients with OSCC. In addition, Focal adhesion and ECM-receptor interaction pathways were found to be involved in OSCC. CONCLUSIONS : FOXD2.AS1 might be a prognostic marker for OSCC and our study may provide more information to the further study in OSCC.

Published: July 2020

Background: Dementia has been described as the greatest global health challenge in the 21st Century on account of longevity gains increasing its incidence, escalating health and social care pressures. These pressures highlight ethical, social, and political challenges about healthcare resource allocation, what health improvements matter to patients, and how they are measured. This study highlights the complexity of the ethical landscape, relating particularly to the balances that need to be struck when allocating resources; when measuring and prioritizing outcomes; and when individual preferences are sought. Objective: Health outcome prioritization is the ranking in order of desirability or importance of a set of disease-related objectives and their associated cost or risk. We analyze the complex ethical landscape in which this takes place in the most common dementia, Alzheimer’s disease. Methods: Narrative review of literature published since 2007, incorporating snowball sampling where necessary. We identified, thematized, and discussed key issues of ethical salience. Results: Eight areas of ethical salience for outcome prioritization emerged: 1) Public health and distributive justice, 2) Scarcity of resources, 3) Heterogeneity and changing circumstances, 4) Knowledge of treatment, 5) Values and circumstances, 6) Conflicting priorities, 7) Communication, autonomy and caregiver issues, and 8) Disclosure of risk. Conclusion: These areas highlight the difficult balance to be struck when allocating resources, when measuring and prioritizing outcomes, and when individual preferences are sought. We conclude by reflecting on how tools in social sciences and ethics can help address challenges posed by resource allocation, measuring and prioritizing outcomes, and eliciting stakeholder preferences.
Research on satellite remote sensing image fusion algorithm based on compression perception theory
Authors: Chi Zhifeng
Published: July 2020

With the development of space technology in recent years, various spacecraft with different sensors have been launched one after another, and there are more and more satellite remote sensing images in different situations. How to obtain better quality images has become the main research direction in the field of image fusion. Image fusion is an important branch and main research object of information fusion. Generally speaking, with the rapid development of the information society, people have higher and higher quality requirements for a variety of images, so There are serious challenges in storing, transmission and signal sampling. Nowadays, with the development of compressed sensing (CS) theory, a new sampling method has been extensively studied by many scholars. Compared with traditional Nyquist sampling theorem, Compression sensing can respond to the original signal with fewer sampling points. This paper is introduced the fusion algorithm of satellite remote sensing image based on compressed sensing. Firstly, the basic theory of compressed perceptual discretization signal is introduced. Secondly, a sparse CS remote sensing image fusion algorithm based on wavelet transform is proposed. Finally, through simulation verification, comparing the widely used IHS fusion and PCA fusion image methods, the method in this paper can get higher correlation coefficient and lower interaction entropy and spectral distortion after fusion. Compared with other methods in this paper, the fusion image can carry more space information and the original image is more similar.

The use of animal models in Parkinson’s disease research has been controversial in terms of how well they relate to the clinical condition and thus their utility for translating therapies from the lab to the clinic. In this article, two researchers debate this issue with Roger Barker taking the view that such models are not useful and may even be misleading, while Anders Björklund defends their use and highlights their value in better understanding and treating this condition.
Capsular distention for adhesive capsulitis in a pediatric patient with acute flaccid myelitis: A case report
Authors: Levin Jared , Siddiqi Asad Raiz , Kim Heakyung
Published: July 2020

INTRODUCTION: Acute Flaccid Myelitis (AFM) is a recently recognized pediatric condition characterized by flaccid paralysis that can cause lifelong deficits. Adhesive Capsulitis (AC) is a chronic condition that causes loss of passive range of motion in the shoulder due to joint contracture. CASE REPORT: This is a case report of a 15-year-old male who suffered from shoulder pain with progressive loss of passive range of motion after AFM, diagnosed with AC based on exam and radiology. After failing conservative management, the patient was successfully treated with ultrasound guided corticosteroid injection. DISCUSSION/CONCLUSION: AC is uncommonly reported in pediatric patients. However, secondary adhesive capsulitis is frequently associated with disorders of shoulder immobility in adults. This case contributes to the body of literature regarding pediatric frozen shoulder, highlights the successful use of ultrasound guided injections for management, and suggests a relationship between AFM and AC which may be beneficial for pediatric physiatrists in treating patients with shoulder pain or immobility related to this condition.
The actual and potential impact of the novel 2019 coronavirus on pediatric rehabilitation: A commentary and review of its effects and potential disparate influence on Black, Latinx and Native American marginalized populations in the United States
Authors: Sholas Maurice G.
Published: July 2020

The COVID-19 pandemic has had a significant health impact around the world. In the United States, there has been a difference in infection and death rates for Black Americans and other marginalized groups as compared to White Americans. Although children do not seem to be suffering infection, morbidity and mortality to the same degree as adults, there is concern that COVID-19 could have a disparate impact on children with acquired or congenital disabilities when analyzed through the lens of race and equity. The possibility that there could be a differential effect on rehabilitation services relates to: the risk of familial/parental exposure leading to secondary infection, the negative economic impact of public health measures required to control disease spread, and the pre-existing social factors that impact access to healthcare. Finally, the psychosocial stresses imposed by COVID-19 inflame risk factors for non-accidental injury, which could lead to an increased need for pediatric rehabilitation services in vulnerable populations. It is critical that individual providers, as well as the health systems in which they practice, actively focus on mitigating personal and systemic causes of racial and ethnic health outcome disparities. These efforts need to move beyond a race neutral construct to specifically anti-racist activity.
Investigation of influence of plate rolling parameters on the product quality
Authors: Kawalek A. , Dyja H. , Ozhmegov K.
Published: July 2020

During plate rolling in most cases a breakdown of symmetry conditions of the strip deformation relative to the upper and lower rolls takes place. The rolling process becomes an asymmetric one. This phenomenon causes an adverse bending of the strip towards the lower or upper roll. Subsequent finishing operations do not ensure the exclusion of the deformed (wavy) shape, since the strip has a high rigidity. With this production, large technological waste, associated with the undulation of the front end of the strip arises. In addition, the work rolls of the rolling mill and auxiliary equipment are subject to increased wear. The introduction of controlled asymmetry into the rolling process by differentiating speed of rotation of the work rolls can be one of the ways to prevent this phenomenon. Using of asymmetry allows to change the stress and strain state in the deformation zone. This method does not increase the load on the rolling stand and the gear of the rolling mill. The paper presents results of investigation of plate rolling parameters (billet feeding angle, degree of deformation, value of the asymmetry coefficient of rolls rotation speed) on the strip curvature. The work was carried out according to conditions of hot rolling of steel grade S355J2+N. For numerical simulation of the rolling process the coefficients of the Hensel–Spittel function were refined. The authors conducted a study of rolling of plates using two types of asymmetry, a geometric (as a result of feeding the workpiece at an angle) and a kinetic (by changing the speed of rotation of individual rolls). The analysis of the results was carried out using numerical simulation based on the modern Forge soft- ware package. According to the results of the work, an analysis of the influence of the parameters of plates hot rolling on the metal flow in the deformation zone is presented. The conditions for reducing the curvature of the end of the strip are determined. The expediency of introducing a controlled asymmetric rolling process by application of different speeds of rotation of the work rolls is shown.
Perfection of a technology of processing and utilization of fine fractions of dump slag
Authors: Sorokin Yu. V. , Demin B. L. , Smirnov L. A. , Kalimulina Е. G.
Published: July 2020

Processing of old dumps slag at crushing-sorting facilities results in a large yield of slag fine fractions – screening. Because of high content of metal inclusions and powder-like fraction in the screening, this product often becomes unclaimed and is returned to dump. Magnetic separation can increase the consumer properties of the slag screening, but it is only magnetic product that is returned to the processing while the mineral part is left in the dump. Basic characteristics of 0–10 mm fraction quoted. It was determined by laboratory study, that after extraction of ferromagnetic inclusions, the true screening density decreased by 17.5% and bulk density – by 3.1%. The powder-like inclusions remain in the screening, that does not allow to consider the material as a filler for concrete and macadam-sand mixture for road-building. To recycle the magnetic product, extracted out of the screening, decreasing of slagging is needed, as well as systematic evaluation of sulphury inclusion content in it. It was proposed to divide the slag screening for macadam and sand fractions after maximum possible removal magnetic inclusions and powder-like inclusions. It will allow to return into the utilization a part of iron previously lost with the fraction 0–10 mm and to obtain an iron concentrate for sintering. The remained tails in the form of macadam of 5–10 mm fraction, sand 0–5 mm and meliorant with decreased iron content can be used in construction industry and agriculture. By field tests it was determined, that adding meliorants, which contain a grinded screening with oxides of magnesium, phosphor and microelements, into soil, results in increasing crop capacity of vegetables by 30% at test areas.

Published: July 2020

In this study, we reported the eco-friendly fabrication of Ag2O–MnO2/GRO nanocomposites by the solid-state mixing of separately prepared GRO and Ag2O–MnO2 NPs using ball milling method, a mechanochemical approach. The prepared material was studied for the catalytic effect of GRO in the system for the aerial oxidation of a variety of alcohols. It was found that the (1%)Ag2O–MnO2/(5 wt.%)GRO nanocatalyst demonstrated a high conversion ability (~100%) and excellent selectivity in the presence of O2 as a clean oxidant. The higher catalytic properties of the nanocomposite were attributed to the presence of GRO, which exhibited extraordinary catalytic properties like improved surface area, excellent chemical compatibility, and stability, as well as the introduction of several defects in the obtained nanocomposite that enhance the catalytic performance. The specific activity of 13.3 mmol·g−1·h−1 is obtained for the catalyst i.e. (1%)Ag2O–MnO2/(5 wt.%)GRO, which is reportedly superior to the various other catalysts previously reported in the literature for the same conversion reaction. Our catalytic strategy was highly selective, producing only desired products with no over-oxygenation to carboxylic acids. The merits of our catalytic methodology were: (a) facile process, (b) inexpensive and clean oxidant, (c) no surfactants or nitrogenous bases were required, (d) mild catalytic conditions, (e) cost-effective recoverable catalyst, (f) complete convertibility, (g) full selectivity, (h) rapid process, and (i) applicable to virtually all types of alcohols. So, these highlights made this catalytic strategy to be highly applicable in the industrial applications for manufacturing of carbonyls. To the best of our knowledge, this was the first study of utilizing Ag2O–MnO2/GRO composite as a catalyst for the oxidation of alcohols, highlighting the catalytic efficiency of GRO.

Foodborne diseases (FBDs) comprise a broad spectrum of illnesses that result from the ingestion of contaminated foodstuffs or water. FBDs can occur at any stage, from production to food consumption, and contamination may be the result of environmental contamination, such as pollution of water, soil, or air [1]. FBDs represent one of the most critical public health problems in the world, especially in developing countries that present serious shortcomings in infrastructure and basic sanitation [2–5]. With the knowledge to prevent FBDs, and the concerns about the increase in FBD cases arising in households, it is essential to evaluate homes’ good food preparation practices.

Öğrencinin başarılı olması için okul ve aile işbirliğinin kurulması, bu işbirliğinin kurulması sürecinde de okula yönelik velilerin bakış açısı önemlidir. İlkokul ve sınıf öğretmeni kavramları velilerin eğitim süreçlerinde karşılaştıkları ilk kavramlardır. Bu kavramlara yönelik oluşturdukları bilişsel fonksiyonlar önemli olup bilişlerinde oluşan bu kavramları da dilsel anlatımlar ile ifade etmektedirler. Velilerde bu kavramlara ilişkin oluşan dilsel anlatımları ortaya koymada zihinsel imgelerin (metaforlar) kullanılması anlamlandırma için önemlidir. İlkokul ve sınıf öğretmeni birinci sınıfa yeni başlayan bir öğrenci için birbirine çok yakın iki kavram olduğundan dolayı her iki kavram için üretilecek olan mecazların bütüncül bir değerlendirme yapmak için faydalı olacağı düşünülmüştür. Araştırmanın amacı; ilkokul birinci sınıfta öğrencisi olan velilerin, ilkokul ve sınıf öğretmeni kavramına ilişkin algılarının belirlemektir. Araştırma nitel araştırma yöntemlerinden olgubilim yöntemi ile desenlenmiştir. Araştırmanın çalışma grubunun belirlenmesinde amaçsal örnekleme yöntemlerinden ölçüt örnekleme yöntemi kullanılmıştır. Çalışma grubu, 2019 – 2020 eğitim öğretim yılında birinci sınıfta öğrencisi bulunan 63 veliden oluşmaktadır. Katılımcıların belirlenen kavramlarla ilgili algılarının ortaya konulması amacıyla veri toplama aracı olarak iki adet açık uçlu sorudan oluşan bir form kullanılmıştır. Formda yer alan “ İlkokulu ……. benzetirim; çünkü ……..” ve “Sınıf öğretmenini ……… benzetirim; çünkü ……..” ifadelerinin katılımcılar tarafından tamamlanması istenmiştir. Anket sorularında yer alan veriler, içerik analizi tekniği ile analiz edilmiş ve yorumlanmıştır. Araştırma sonucunda katılımcıların ilkokul ve sınıf öğretmeni kavramına yönelik algılarının olumlu yönde olduğu belirlenmiştir.

Disiplinlerarası yaklaşım; belirli bir kavram, problem ya da konuyu farklı açılardan aydınlatabilecek farklı derslerin bir araya getirilerek ele alınması olarak tanımlanabilir. Bu yaklaşımın öğrenme ve öğretme sürecinde kullanılması sürecin uygulayıcısı konumunda olan öğretmenlerin görüşlerini önemli hale getirmektedir. Bu araştırmanın amacı Sosyal Bilgiler derslerinde disiplinlerarası yaklaşımın kullanımına yönelik öğretmen görüşlerini ortaya çıkarmaktır. Araştırma nitel araştırma modellerinden biri olan olgubilim deseni olarak tasarlanmıştır. Araştırmanın çalışma grubunu, Türkiye’nin çeşitli illerinde Milli Eğitim Bakanlığı’na bağlı ortaokullarda görev yapan ve araştırmaya gönüllü olarak katılmayı kabul eden 18 Sosyal Bilgiler öğretmeni oluşturmaktadır. Elde edilen veriler içerik analizi tekniği kullanılarak analiz edilmiştir. Araştırma sonucunda öğretmenlerin disiplinlerarası yaklaşımı önemli ve gerekli, faydalı ve öğrenmede etkili ve öğrenci gelişimi açısından olumlu gördükleri görülmektedir. Sosyal Bilgiler öğretmenleri en fazla Türkçe, Fen Bilgisi ve Din Kültürü ve Ahlak Bilgisi derslerinden faydalanmakta ve öğretmenleri ile işbirliği yapmaktadırlar. Öğretmenler disiplinlerarası bağlantı kurarken kazanım ve öğrenme alanı ile konunun anlaşılması ve öğrenilmesine dikkat ettiklerini belirtmektedirler. Öğretmenler yaklaşımın en fazla eksiklikleri tamamlamada yararlı olduğunu düşünmektedirler. Yaklaşımın sınırlılığı konusunda ise öğretmenler öğrenciye ve konuya uygunluğu ile öğretmen yeterliliği noktasında sorunlar yaşadıklarını belirtmektedirler.

Authors: Platonova A. Z. , Vasilieva Y. V. , Lukina F. A.
Published: July 2020

Relevance. At present in the region the range of potatoes does not meet modern phytosanitary requirements, there is a decrease in potato yield over a long period of time. [1–6, 14]. Modern biotechnology techniques have undeniable advantages and allow for the early development of potato starting material to determine future crop crossing patterns. Effective implementation of such works is ensured by careful selection of accounts and observations of the growth and development of potato clones.

Methods. The material is potato clones in vitro. The aim of these studies is to study the growth and development of potato plants in vitro in microlonal reproduction.

Results. As a result, the influence of signs of correlation relationships in plants-regenerants of potatoes of 6 varieties (Lubava, Ilinsky, Rodrigo, Handsome, Alvara and Velikan) on the indicators of development of the above-ground part of the plant (height of plants and number of intersections), as well as indicators of rhizogenesis (number and length of roots) was found. Both the positive relationship of the characteristics of the number of intersections, the height of plants, and the negative relationship of the characteristics in potato varieties under in vitro conditions have been established here. With higher plant height, there is a tendency to increase the number of intersections, the biomass of the plant, and the length of the roots in the varieties Handsome, Alvara, Rodrigo. The Great variety did not show a direct relationship between plant height and the mass of leaves, stems. The standard Lubava variety reflected a weakly negative relationship between plant height and root length. The variety Ilinsky did not depend on the height of the plants and the length of the roots, which cannot be noted in the varieties Handsome, Rodrigo and Alvara. According to the selected varieties, the largest correlation coefficient of plant height and root length is observed in Beauty variety (r = 0.69), then in Alvar variety (r = 0.43), Rodrigo variety (r = 0.20). The remaining varieties had a weak correlation.
