Authors: Ivenin Aleksey , Bogomolova Yuliya , Sakov Aleksandr
Published: April 2021

The research was carried out in order to find new technological and technical solutions that ensure the economic efficiency of farming, stabilization and increase of crop yields due to the rotation of grain crop rotation in the conditions of the southeast of the Volga-Vyatka region. The field experience was established in 2014 in the Nizhny Novgorod region. Scientific research was carried out in the grain crop rotation: 1. mustard for seeds 2. winter wheat; 3. soy; 4. spring wheat; 5. peas; 6. oats. The scheme of the experiment included 5 tillage systems (factor A), which differ in the methods of the main finch tillage. For each tillage system, the effect of mineral fertilizers at a dose of N60P60K60 and destructors of plant residues (ammonium nitrate at a dose of 10 kg a.i. per 1 ton of straw and the biological product Stimix®Niva) was determined (factor B). All the studied tillage systems and applied mineral fertilizers with straw destructors allow for expanded agricultural production. The lowest conditional profitability of production was found for the traditional tillage system using a plow with dumps - 99.3 %, which is 34.6% lower than the conditional profitability in the field experiment variants using disking as the main autumn tillage - which provides the highest average conditional profitability of 133.9 %. The average conditional profitability of grain production using the No-till technology for the rotation of the grain crop rotation was 123.3 %, which is 24.0 % higher than the conditional profitability of traditional tillage and 10.6 % lower than that of the resource-saving technology of agricultural production using a disc harrow. At the same time, the direct sowing technology provides the highest absolute profitability of grain production for the rotation of a six-field crop rotation in the conditions of the southeast of the Volga-Vyatka region when cultivating crops according to N60P60K60 background together with the use of the biological product Stimix®Niva – 170.9 %

Published: April 2021

The article presents the results of studies of the influence of soil cultivation methods, mineral fertilizers and biofungicide on yield, grain quality of spring wheat and economic indicators. The studies were carried out in 2018-2020. The soil of the experimental site is represented by slightly leached heavy loamy chernozem with a humus content of 5.8%. The object of research is spring wheat, grade “Ulyanovskaya 100”. The subject of research is six methods of soil cultivation: 1) moldboard - (plowing by 20-22 cm PLN-4-35) control; 2) differentiated - (plowing 25-27 cm for the previous crop, disking 6-8 cm for spring wheat); 3) mulching - (by 10-12 cm APK-3 in spring); 4) comb - (OP-3S for 13-15cm); 5) disk - (paper machine for 6-8cm); 6) flat-carved - (KPSh-3 by 13-15cm). The experiment was carried out on four backgrounds: 1) N0P0K0 (control); 2. Background (N30P30K30 - for pre-sowing cultivation); 3. “Fitotrix”; 4.Background N30P30K30 + Fitotrix. The experiment was repeated four times. The arrangement of the plots is systematic, the total area of the plot is 250 m2 (10 x 25), the accounting area is 125 m2 (5 x 25). The highest yield - 3.73 t/ha, was achieved with the use of differentiated tillage, here the profitability of grain production was 161%, the energy efficiency coefficient was 3.51 units, against plowing, where the indicators were respectively by 0.15 t/ha, 52% and 0.43 units below. The greatest responsiveness in the harvesting of grain from fertilizers was observed in the variant with ridge cultivation, where the increments were 0.49 t/ha against the background of the application of N30P30K30, against the background of N30P30K30 + “Fitotrix” - by 0.96 t/ha relative to the non-fertilized background. The quality characteristics of the grain were similar regardless of the main tillage methods. The highest indicators were observed in the combination of biofungicide with mineral fertilizers, where the increase in gluten and protein was 3.4 and 1.1%, compared with the non-fertilized background

Published: April 2021

The work is devoted to the assessment of the impact of a single oil pollution of the soil on the yield and disease incidence of spring rape plants (Brassica napus L.). The study was conducted in experimental site of agrochemistry and soil science department of Kazan State Agrarian University, which is located in Predkamye zone of Tatarstan Republic. The soil in experimental site is clay loamy gray forest soil, which is typical for this zone. The main nutrient properties of uncontaminated soil was low content of humus, slightly high content of labile Phosphorous and moderate availability of labile Potassium, the pH was slightly acid. The soil was intentionally contaminated by crude oil on soil surface at the rates of 10, 20 and 40 l/m2. Based on the previous research, the contamination levels in this study are presented as low, moderate and high levels. The yield of oilseeds of spring rape was closely correlated with the level of one-time pollution of gray forest soil with crude oil over at least 15 years. The results showed that the increase of downy mildew abundance (R2=0,8804) and development(R2=0,8610) correlated with the soil contamination level. Consequently, both abundance and development of downy mildew induced asignificant negative effect on the yield of the main and side rape production. The strength of oil seeds production correlation with the level of plant infection (R2=0,8652÷0,8759) was more significant as compared to the correlation strength with the decrease of rape shoot yield (R2=0,8013÷0,8192)

ECONOMY OF OBTAINING PLANNED SPRING WHEAT YIELDS ON AROUND CHERNOZEM DUE TO MINERAL FERTILIZER
Authors: Eremina Diana , Demina Oksana
Published: April 2021

In modern conditions of agricultural intensification, the use of a scientifically based fertilizer system becomes extremely necessary. It is she who will allow you to get economically viable crop yields. Studies to obtain the planned yield with the introduction of increasing doses of mineral fertilizers were carried out in 2018-2020 in the forest-steppe zone of the Urals. The soil is old leached chernozem. Experiment scheme: control (without fertilization); application of mineral fertilizers to the planned yield: by 3.0 t/ha of grain N40 P75; 4.0 t/ha - N95P110; 5.0 t/ha - N150P200 and 6.0 t/ha - N185P160 kg of active ingredient. On average, over the years of research, the planned yield of spring wheat was achieved. The cost of growing spring wheat without mineral fertilizers amounted to 16850 rubles/ha. The introduction of mineral fertilizers for the planned harvests increases costs up to 34200 rubles/ha. Such high costs are explained by the use of phosphate fertilizers, whose price is twice as high as ammonium nitrate. In the structure of costs for obtaining a yield of 3.0 t/ha of grain, the share of mineral fertilizers accounts for 17 %. A further increase in the level of mineral nutrition through fertilizers increases the share of fertilizer costs up to 45 %. The profit from the sale of grain on the option with NPK of 6.0 t/ha of grain reached 27400 with a profitability of 80 %. On the control, the corresponding indicators were 5150 rubles/ha and 31 %. The optimal and economically justified is the level of mineral nutrition, providing 4.0 t/ha of spring wheat grain. A further increase in the agricultural background is associated with a risk due to the peculiarities of weather conditions in the forest-steppe zone of the Urals
THEORETICAL JUSTIFICATION OF THE ASSESSMENT OF THE TECHNICAL CONDITION OF THE INTERNAL COMBUSTION ENGINE BY THE VALUE OF THE TOTAL EMF IN FRICTION PAIRS
Authors: Salahutdinov Il'mas , Gluschenko Andrey , Molochnikov Denis , Petryakov Sergey , Gayaziev Ilnar
Published: April 2021

The research was carried out in order to determine the possibility of assessing the technical condition of an internal combustion engine (ICE) by the value of the total electromotive force (EMF) that occurs in its friction pairs. The contact area of the rubbing parts and the gap between them affects the electrical resistance in contact, and, accordingly, the value of the resulting EMF according to the established dependence. To confirm the theoretical results, studies were carried out on the UMP-417 engine using a developed measuring complex and a manufactured current-collecting device mounted on the output end of the engine crankshaft. With the operating mode corresponding to the speed of the crankshaft 800 min-1, the total value of the EMF in the measurement circuit cylinder liner-engine block-crankshaft-current collector (TSU) was 83...95 mV. At the same time, in the piston–cylinder liner friction pair, it was equal to 37 ... 47 mV, and in the crank mechanism friction pairs - 46...48 mV. The correspondence of the results of the theoretical calculation and bench studies of the values of the EMF value for a real internal combustion engine was: when measured using the Fluke device for the friction unit of the cylinder liner-piston – 62.1 %, for the friction units of the crank mechanism (root neck-connecting rod, connecting rod neck-connecting rod, root neck-engine block) - 15.1 %. When measured by the V1net device, for the cylinder liner – piston friction unit-85.5 %, for the crank mechanism friction units (root neck-connecting rod, connecting rod neck-connecting rod, root necks-engine block) - 93.2 %. The proposed method for determining the state of the engine by the value that occurs in its EMF friction nodes can be used in the technical diagnostics of engines

Published: April 2021

We developed a simple and compact laser-scanning photoacoustic microscopy (PAM) for imaging large areas of subcutaneous microvasculature in vivo. The reflection-mode PAM not only retains the advantage of high scanning speed for optical scanning, but also offers an imaging field-of-view (FOV) up to 20 × 20 mm2, which is the largest FOV available in laser-scanning models so far. The lateral resolution of the PAM system was measured to be 17.5 µm. Image experiments on subcutaneous microvasculature in in vivo mouse ears and abdomen demonstrate the system's potential for fast and high-resolution imaging for injuries and diseases of large tissues and organs.

Published: April 2021

Integrated semiconductor mode-locked lasers have shown promise in many applications and are readily fabricated using generic InP photonic integration platforms. However, the passive waveguides offered in such platforms have relatively high linear and nonlinear losses that limit the performance of these lasers. By extending such lasers with, for example, an external cavity, the performance can be increased considerably. In this paper, we demonstrate for the first time that a high-performance mode-locked laser can be achieved with a butt-coupling integration technique using chip scale silicon nitride waveguides. A platform-independent SiN/SU8 coupler design is used to couple between the silicon nitride external cavity and the III/V active chip. Mode-locked lasers at 2.18 GHz and 15.5 GHz repetition rates are demonstrated with Lorentzian RF linewidths several orders of magnitude smaller than what has been demonstrated on monolithic InP platforms. The RF linewidth was 31 Hz for the 2.18 GHz laser.
Scaling properties of guided acoustic-wave Brillouin scattering in single-mode fibers

Published: April 2021

We investigate guided acoustic-wave Brillouin scattering (GAWBS) in single-mode optical fibers. By treating the discrete GAWBS spectrum as a continuum, we propose a closed-form formula to evaluate the GAWBS variance due to radial modes, showing its dependence on the inverse of the fiber effective area. The formula is checked against an experimental validation at variable signal power. The almost flat experimental results with power suggest that GAWBS dominates stimulated electrostriction. We also compare GAWBS with the Kerr effect showing their common grounds and their main differences. The phase noise characteristics of the nonlinear interference induced by GAWBS is investigated, showing that in ultra-long links GAWBS can be safely taken as a circular white noise. The theoretical results can be used for quick estimations of the GAWBS penalty with any fiber effective area. In particular, we estimated a GAWBS penalty on the signal-to-noise ratio (SNR) of 0.5 dB after 6000 km with fibers of effective area 150 μm2.

Published: April 2021

Lighting design is an essential aspect of interior design but very few universities offer students the opportunity to study lighting design in depth as part of their Council for Interior Design Accreditation (CIDA)-accredited undergraduate interior design program. This paper makes a
case for including lighting design as an indispensable part of interior design education while also promoting the Family and Consumer Sciences Body of Knowledge (FCSBOK). The rapid and ongoing advancements being made in luminaire design, lighting controls, and energy conservation necessitate
attention and expansion of lighting design education within interior design programs.
When Traditional Gender Roles Clash With Contemporary Expectations: A Call To Redefine Success in the Modern World
Authors: Zorotovich Jennifer , Dove Meghan , Myers Beth
Published: April 2021

What it means to be successful in many careers today is best captured by Slaughter (2012): The American definition of a successful professional is someone who can climb the ladder the furthest in the shortest time.... It is a definition well suited to the mid-20th
century, an era when people had kids in their 20s, stayed in one job, retired at 67, and were dead, on average, by age 71. (p. 17) Contemporary patterns of work and family life look markedly different with people commonly postponing marriage and parenthood in favor of postsecondary
education and career preparedness. American homes are increasingly dependent on women's incomes (Glynn, 2016) and women today are becoming mothers at a higher rate than they were 10 years ago, which is especially true for women with advanced degrees (Geiger et al., 2019). This then creates
a unique intersection between work and family life that is particularly complex for working mothers. For instance, both mothers and fathers today spend more time on child care than previous generations did, but women also are tasked with figuring out how to spend more time at work; indeed,
employers increasingly are requiring workers to dedicate more hours to their profession in order to advance (Dotti Sani & Treas, 2016; Geiger et al., 2019; Goldin, 2015). Although both men and women report struggles with balancing contemporary work and family life, more mothers than fathers
express this difficulty (Geiger et al., 2019).

Published: April 2021

The article presents current data on synovitis (inflammation of the synovial membrane), which is often the only clinical manifestation of osteoarthritis (OA), and considered to be one of the risk factors for the OA development. Synovitis severity correlates with the severity of OA symptoms. The assessment of the prevalence of synovitis presents significant difficulties and depends on the nature and severity of the disease, the cohort in question, diagnostic method, and therapy. The classification based on etiological, clinical and histological characteristics of synovitis is presented. Examination of synovial tissue characteristics and its changes during inflammatory response can significantly expand the possibilities for therapy and prognosis. The use of symptomatic delayed-action drugs (SYSADOA) is considered as the basic treatment of OA. Chondroitin sulfate (Chondroquard®) is one of the well established drugs, it has symptom- and structural-modifying properties. The article presents the results of studies confirming its effectiveness in reducing the severity of knee synovitis.

Authors: Ahmadi Anas
Published: April 2021

This study explores the character of Takezo the ronin in Musashi by Eiji Yoshikawa through the psychological perspective of aggression. This research specifically aims to (a) explore Takezo's psychology of aggression as a ronin and (b) the impact of Takezo's aggression on others. The approaches used in this research are the psychology of literacy and the psychology of aggression. The method used is qualitative; it uses data exposure and interpretation. The data source is the novel Musashi by Eiji Yoshikawa (translated version in Indonesian). The data used is in the form of text that is relevant to Takezo's psychology of aggression. The data analysis techniques are carried out in five stages, (1) identifying data related to Takezo's psychology of aggression, (2) data classification related to Takezo's psychology of aggression, (3) data presentation related to Takezo's psychology of aggression, and (4) summarizing data related to Takezo's psychology of aggression. The results showed that Takezo's aggressions are represented in the form of thoughts and behaviour. Takezo's aggressive thoughts are wanting to defeat and kill his enemies. Takezo's aggressive behaviour is killing his enemies, who are samurai. Takezo's aggressions cause the impact of physical category, and they are death and disability on the defeated samurai. Besides, in the psychological category, Takezo's aggressions cause fear and hatred in society. It is concluded that Takezo represents ronin, which desires destructive aggression that has a physical and psychological impact on others.

Published: April 2021

The article deals with the insufficiently studied problem of variegated alfalfa and eastern galega presowing seed treatment, which can serve as an excellent reserve for increasing their forage productivity. The quality of the seeds determines the stand density of perennial grasses and their yield. The studies have been performed on sod-podzolic medium loamy soil. The authors studied the effect of molybdenum-acid ammonium (300 gm/t), Rhizotorphine bacterial preparation (for variegated alfalfa – 0.5 l/t, for eastern galega – 1.0 l/t), HB-101 plant growth regulator (1 ml/t), and Agree's Forsage complex fertilizer (1.2 l/t) upon cultivating the studied crops. The consumption rate of the working solution (water + preparation) was 10 litres per ton of seeds. The accounting plot area was 33 m2. Perennial legumes were sown after spring rapeseed; the seeding rate for variegated alfalfa was 14 kg/ha, for eastern galega – 26 kg/ha. It has been found that introducing seed treatment with the Agree's Forsage complex fertilizer increases productivity by 23–47% due to increasing the field germination of variegated alfalfa by 10–15% and eastern galega by 4–10%, and due to increasing the number of nodule bacteria by 6–13 per plant and 8–16 per plant respectively.
Estimating Query Timings in Elasticsearch
Authors: Bagui Sikha , Fridge Evorell
Published: April 2021

In a shared Elasticsearch environment it can be useful to know how long a particular query will take to execute. This information can be used to enforce rate limiting or distribute requests equitably among multiple clusters. Elasticsearch uses multiple Lucene instances on multiple hosts as an underlying search engine implementation, but this abstraction makes it difficult to predict execution with previously known predictors such as the number of postings. This research investigates the ability of different pre-retrieval statistics, available through Elasticsearch, to accurately predict the execution time of queries on a typical Elasticsearch cluster. The number of terms in a query and the Total Term Frequency (TTF) from Elasticsearch’s API are found to significantly predict execution time. Regression models are then built and compared to find the most accurate method for predicting query time.
Characterization of nano-additive filled epoxy resin composites (ERC) for high voltage gas insulated switchgear (GIS) applications
Authors: Hari Rathod , Mohana Rao Mandava
Published: April 2021

Insulation based on epoxy resin (ER) is widely used for high voltage and high fault current rated electrical substation equipment. This paper details the formulation of epoxy based Nano-composites and influence of the Nano filler material on the electrical and thermal properties like breakdown voltage (BDV), relative permittivity, tanδand thermal conductivity of the epoxy resin composites (ERC). The nano-filler materials such as alumina (Al2O3), silica (SiO2) and titania (TiO2) are considered for the study. Diglycidyl ether of biphenyl-A (DGEBA) type epoxy resin CY5950 and acid anhydride hardener HY5951 are used for development of samples/insulated spacers. Scanning electron microscopy (SEM) images have been established for various ER composites to understand how the dispersion of nano-filler material influences the performance parameters of the samples. In the present study, the sample preparation with metallic inserts has shown additional advantages compared to existing practice of purely insulated samples. Developed samples help to estimate electrical and mechanical properties more accurately. Most appropriate nano filler is identified based on the test results obtained on samples developed in the study. Finally, by using the identified epoxy–filler composite, insulated spacers for 145 kV GIS have been developed and evaluated for electro-mechanical parameters. Necessary dielectric tests have been carried out on developed insulated spacer as per IEC.

Interpretation and use of standard atomic weights (IUPAC Technical Report)
Authors: van der Veen Adriaan M. H. , Meija Juris , Possolo Antonio , Hibbert David Brynn
Published: April 2021

Many calculations for science or trade require the evaluation and propagation of measurement uncertainty. Although relative atomic masses (standard atomic weights) of elements in normal terrestrial materials and chemicals are widely used in science, the uncertainties associated with these values are not well understood. In this technical report, guidelines for the use of standard atomic weights are given. This use involves the derivation of a value and a standard uncertainty from a standard atomic weight, which is explained in accordance with the requirements of the Guide to the Expression of Uncertainty in Measurement. Both the use of standard atomic weights with the law of propagation of uncertainty and the Monte Carlo method are described. Furthermore, methods are provided for calculating uncertainties of relative molecular masses of substances and their mixtures. Methods are also outlined to compute material-specific atomic weights whose associated uncertainty may be smaller than the uncertainty associated with the standard atomic weights.

Objectives

Ege University Medical School initiated system based integrated clinical internship in 2011. The need for a mentor who would closely monitor and guide the student in knowledge and skill gains for every clinical internship block and who would be an academic role model was well established. The aim of this study reports the results of the clinical internship mentoring program in the Ege University Medical School.

Methods

The Clinical Internship Counseling Committee reviewed similar programs in the literature, conducted focus group discussions, determined the wishes and needs of the students, and developed a mentoring program.

Results

The program was initiated by announcing the student-mentor matches and the procedure which was based on meetings of the student-mentor at the 1st, 8th and 13th weeks of the integrated internship. This meeting was designed to be a time for the mentor to guide the student to achieve the internship goals, to establish his/her internship progress file and to be an academic role model. At the final evaluation of the mentor, communication between student and the progress in the establishment of the internship progress file contributed to the 5% of the final internship success grade.

Conclusions

Evaluation of 7 years of experience led to the agreement that the goals of clinical internship program should be integrated into the newly established “Student Mentorship Program” that starts at the 1st year of the medical school.
Pressure dependent ultrasonic properties of hcp hafnium metal
Authors: Singh Ramanshu P. , Yadav Shakti , Mishra Giridhar , Singh Devraj
Published: April 2021

The elastic and ultrasonic properties have been evaluated at room temperature between the pressure 0.6 and 10.4 GPa for hexagonal closed packed (hcp) hafnium (Hf) metal. The Lennard-Jones potential model has been used to compute the second and third order elastic constants for Hf. The elastic constants have been utilized to calculate the mechanical constants such as Young’s modulus, bulk modulus, shear modulus, Poisson’s ratio, and Zener anisotropy factor for finding the stability and durability of hcp hafnium metal within the chosen pressure range. The second order elastic constants were also used to compute the ultrasonic velocities along unique axis at different angles for the given pressure range. Further thermophysical properties such as specific heat per unit volume and energy density have been estimated at different pressures. Additionally, ultrasonic Grüneisen parameters and acoustic coupling constants have been found out at room temperature. Finally, the ultrasonic attenuation due to phonon–phonon interaction and thermoelastic mechanisms has been investigated for the chosen hafnium metal. The obtained results have been discussed in correlation with available findings for similar types of hcp metals.
Idiopathic Bradycardia in Unicuspid Unicommissural Aortic Valve Complicated with Infective Endocarditis and Aortic Root Abscess: A Case Report
Authors: Abd Al Jawad Mohammed Nabil , Refaat Khaled , Attiya Mohammed , Abdelhakim Nada , Abdeltawab Samar
Published: April 2021

Unicuspid aortic valves are among the rarest congenital malformations. They are classified as either acommissural or unicommissural, with the unicommissural being presented in early adulthood. Unicuspid valves share many similarities with bicuspid valves, namely increased rates of valve degeneration and calcification, making them prone to secondary aortic stenosis, regurgitation, or both. Among other similarities are the increased risk of aortic root dilatation, dissection, and left ventricular dilatation. We report our case of a 23-year-old male with unicuspid unicommissural aortic valve with aortic root and left ventricular dilatation. He successfully underwent Wheat procedure.
A New Understanding for Preoperative Management in a Patient with Blunt Brachiocephalic Trunk Injury

Published: April 2021

We report a case of a 24-year-old male patient with blunt brachiocephalic trunk injury, who was given low-dose dexmedetomidine (DEX) for 2 weeks to help smoothly pass the preparation period before the recanalization operation. Because the patient’s vital signs were stable after the injury, the surgeon did not perform emergency surgery. Taking into account the characteristics of blunt brachiocephalic trunk injury, it is necessary to avoid damage to or even rupture of brachiocephalic trunk resulting from irritability and high blood pressure. Patients should be sedated to avoid hemodynamic fluctuations that may be caused by cerebral ischemia and restlessness, and based on the patient’s neurological symptoms, prevention or treatment of perioperative neurocognitive disorders (PNDs) cannot be ignored. Therefore, the choice of drugs for bridging the preoperative preparation stage is crucial. DEX is an α2-adrenergic receptor agonist with antianxiety, analgesic, and sedative effects. It can also stabilize hemodynamics, regulate neuroinflammation, and provide neuroprotection. Instead of using either β-adrenergic receptor antagonists or sedatives, the patient received only low-dose DEX during preoperative preparation. DEX achieved the effects of β-adrenergic receptor blockers, vasodilators, and other sedatives, and it also had certain benefits for the patient’s PND. In short, based on our understanding of the relevant physiological factors, risk factors of brachiocephalic trunk injury, and the effects of DEX, low-dose DEX provides a good option for preoperative management in a patient with blunt brachiocephalic trunk injury.

The world has suffered over the past year under COVID-19. Unfortunately, people still are getting sick from other, also severe, diseases. Although the COVID-19 infection is present, patients need treatment for other life-threatening conditions. We present the case of a 36-year-old patient with severe infective endocarditis with a large abscess of the aortic root, who also is COVID-19 positive. Definitive diagnostics and treatment were avoided due to COVID-19 infection. In the end, emergent surgery was indicated due to acute cardiac decompensation and the development of heart failure symptoms, and the patient recovered uneventfully after surgery.
Group Identity in a Secondary School Classroom Constructed through Musical Creation / Oblikovanje grupnoga identiteta glazbenim stvaranjem u srednjoj školi

Published: April 2021

Music plays an important role in the construction of identity in adolescence. However, few studies have explored the relationship between the formation of group identities in adolescence and musical creation as an experiential group activity in secondary school. Therefore, the aim of the present study was to shed light on the formation of group identities in the classroom and determine the factors involved in this process. An educational project focusing on participatory musical creation was carried out in three Spanish secondary schools, involving 267 students. Data were collected by means of participant and non-participant observation, a classroom diary, a questionnaire and video recordings, analysed within the framework of activity theory. The results revealed the influence of a number of interconnected determinants on the formation of group identity in the classroom: (1) student involvement in all stages of the project; (2) the construction of meaningful musical experiences through the students’ role as musicians; (3) the classroom climate; (4) the emergence of positive emotions; (5) high motivation to learn; and (6) student identification with their own music. These results indicate the useful role of music creation in the formation of group identity. Keywords: activity theory; creative learning; music; participation; secondary education---Glazba ima važnu ulogu u izgradnji identiteta tijekom adolescencije. Unatoč tome, malo je studija istraživalo odnos između oblikovanja grupnih identiteta u adolescenciji i glazbenoga stvaranja kao iskustvene grupne aktivnosti u srednjoj školi. Stoga je cilj ovoga istraživanja bio osvijetliti oblikovanje grupnih identiteta u razredu i utvrditi čimbenike uključene u taj proces. Proveden je obrazovni projekt s fokusom na participacijsko glazbeno stvaranje u tri srednje škole u Španjolskoj. U projektu je sudjelovalo 267 učenika. Podatci su sakupljeni metodama sudioničkoga promatranja, promatranja bez sudjelovanja, razrednoga dnevnika, upitnika i videozapisa, a analizirani su unutar okvira teorije aktivnosti. Rezultati pokazuju utjecaj određenoga broja međusobno povezanih faktora na oblikovanje grupnoga identiteta u učionici: (1) učenički angažman u svim stadijima projekt, (2) stvaranje značajnih glazbenih iskustava kroz učeničke uloge glazbenika, (3) razredno ozračje, (4) javljanje pozitivnih emocija, (5) visoka motivacija za učenje i (6) poistovjećivanje učenika s vlastitom glazbom. Navedeni rezultati otkrivaju pozitivno djelovanje glazbenoga stvaralaštva na oblikovanje grupnoga identiteta. Ključne riječi: glazba; kreativno učenje; sudjelovanje; srednjoškolsko obrazovanje; teorija aktivnosti.
