Особливості анатомії, класифікації травматичних ушкоджень грудного відділу хребта (огляд літератури)
Authors: Teslenko S.O.
Published: July 2022

Перелом хребта — це патологічний стан, що виникає через порушення анатомічної цілісності кісток хребта. Аналіз літератури щодо грудного відділу хребта показав, що цей відділ помітно відрізняється від інших як анатомічно, так і за своїм функціональним призначенням. Хребці грудного відділу анатомічно відрізняються від хребців шийного й поперекового відділів хребта, хоча верхні й нижні хребці мають ознаки суміжних відділів. Основна функція грудного відділу хребта разом з ребрами й грудиною полягає в захисті органів грудної клітки, тому ушкодження складових цього комплексу не можна розглядати окремо одне від одного. Існує декілька класифікацій ушкоджень грудного відділу хребта. На сьогодні найбільш поширеними є: класифікація AO/ASIF (Arbeitsgemeinschaft fur Osteosynthesenfragen/Association for the Study of Internal Fixation); Load-sharing класифікація McCormack et al. і шкала тяжкості травм грудопоперекового відділу хребта (Thoracolumbar Injury Severity Score, TLISS). Кожна з них доповнює і розвиває попередню і залучає в класифікацію все більше ознак ушкоджень грудного відділу хребта, як морфологічних, так і неврологічних. З огляду на особливості ушкоджень грудного відділу хребта і їх анатомію хірургічне лікування вимагає особливого підходу щодо вибору тактики й інструментарію.

Published: July 2022

Анатомічні особливості грудопоперекового переходу визначають значну схильність цієї зони до травматичних ушкоджень. Тактика лікування ушкоджень грудопоперекового переходу досить суперечлива. Запропоновано велику кількість методів, які демонструють ефективність при тих чи інших видах ушкоджень. Однак єдиної концепції, що визначає конкретний метод лікування для певного комплексу патоморфологічних змін, не сформовано. Тенденцією останніх десятиріч є розробка і активне впровадження у клінічну практику тактикоорієнтованих класифікацій травматичних ушкоджень певного відділу хребта, які враховують низку різнорідних чинників та надають клініцисту більш-менш чітку схему лікувальних заходів. Щодо грудопоперекового переходу такою класифікацією є AOSpine Thoracolumbar Spine Injury Classification System. Схему розроблено для характеристики ушкодження грудного та поперекового відділів хребта, але особливості грудопоперекового переходу, як і в раніше запропонованих класифікаціях, не взяті до уваги. Класифікація ґрунтується на оцінці трьох базових критеріїв (морфологічна характеристика перелому, неврологічний статус постраждалого та уточнюючі клінічні модифікатори). Ієрархія розподілу типів травматичних ушкоджень відповідає зростанню ступеня тяжкості. Виділяють три основні типи ушкодження: компресійні травми, неспроможність заднього чи переднього зв’язкового комплексу, ушкодження, що супроводжується зміщенням у будь-якій площині. В огляді наведено детальну характеристику всіх варіантів ушкоджень. Автори AOSpine Thoracolumbar Spine Injury Classification System намагалися створити досить просту, універсальну і добре відтворювану класифікацію для відображення основних хірургічних переваг та визначення найраціональнішого підходу до лікування. Установлено, що, незважаючи на високу відтворюваність результатів, аналізована класифікація фактично є описовим інструментом без визначення будь-якої тактики для конкретного випадку. Як інструмент кількісної оцінки ступеня тяжкості травми розглянуто шкалу тяжкості ушкоджень грудопоперекового відділу хребта, що ґрунтується на класифікації AO. Шкала на підставі суми балів, що характеризує певне ушкодження, дає змогу зробити вибір на користь хірургічного або консервативного лікування. Як найдетальніший алгоритм терапії ушкоджень грудопоперекового відділу хребта розглянуто схему, запропоновану спінальною секцією Німецького товариства з ортопедії і травми. Алгоритм ґрунтується на AOSpine Thoracolumbar Spine Injury Classification System, але використано також низку морфологічних модифікаторів, що дало змогу адекватно визначити найоптимальніший метод лікування певного типу ушкодження.

Published: July 2022

Abstract: Low power is one of the arising trend in field of VLSI which can be used in multimedia bias employing colorful signal processing algorithms and armature. In utmost multimedia operation mortal beings can gather useful information from incorrect afFull Adderir. Thus we don’t need to produce an exact correct numerical afFull Adderir. So we're using different adders to apply this algorithm in signal processing. We design infrastructures for videotape and image contraction algorithms using the proposed approximate computation units and estimate them to demonstrate the efficiency of our approach. We also decide simple fine models for error and power consumption of these approximate adders. The approximate adders are reduced with complexity which are used in designing this algorithm. The proposed adders can achieve significant through afFull Adderir and total power reduction over conventional adders. Simulation results indicate up to 69% power savings using the proposed approximate adders, when compared to being executions using accurate adders.
Parametric Analysis of Flat Slab with Shear Wall Lateral Resisting System Subjected to Dynamic Loading
Authors: H D Lavanya
Published: July 2022

Abstract: In the present project 20 storey structure is modelled using ETABS and loadings are considered as per IS codes. The models were analysed for both static and dynamic time history analysis the results are extracted, graphs are plotted. Models were compared and conclusions are drawn. The conclusions drawn from the analysis are, The Static analysis and dynamic analysis are having different values and time history analysis seems to be more accurate due to consideration of modal analysis and sitespecific analysis. The displacement is the main parameter in terms of serviceability criteria, the time history analysis shows lesser values than static analysis. It indicates that the static analysis may be on higher side for high rise structures. The comparatively huge displacement in case of Model M02 for both static and dynamic analysis proves the flat slab structure without drop panel and shear wall is not acceptable for lateral loading. From the overall analysis, it is found that the Column beam system with shear wall is best system to adopt, however in case of project demand, it is better to adopt flat slab drop panel system with shear wall located at centre as preference. In case of difficulty of shear wall at centre, the shear wall at corners can be adopted.

A Substantiation and Key Agreement Based on Unidentified Identity for Peer-to-Peer Cloud
Authors: Krishna Dr. V Anantha
Published: July 2022

Abstract: Real-time data collected by smart sensors deployed in factories is shared over open channels as the Industrial Internet of Things (IIoT) expands, posing a risk of unauthorised access to transmitted messages by adversaries, resulting in a privacy leakage problem. However, users frequently find it difficult to backup all data from the original cloud servers to their mobile phones in order to upload the downloaded data to the new cloud provider due to insufficient local storage and computational capabilities. To address this issue, it is proposed to gather information on the available solutions for the application of security issues in peer-to-peer networks, with a focus on authentication mechanisms.

TRÊS ONDAS DO ESTUDO DA VARIAÇÃO
Authors: Gomes de Oliveira Samuel , Majolo Rockenbach Lívia , Gutierres Athany
Published: July 2022

O tratamento do significado social na variação sociolinguística organizou-se em três ondas de prática analítica. A primeira onda de estudos de variação estabeleceu amplas correlações entre as variáveis ​​linguísticas e as categorias macrossociológicas de classe socioeconômica, sexo, classe, etnia e idade. A segunda onda empregou métodos etnográficos para explorar as categorias e configurações locais que habitam ou constituem essas categorias mais amplas. Em ambas as ondas, a variação era vista como marca de categorias sociais. Este artigo estabelece uma fundamentação teórica para a terceira onda, argumentando que (a) a variação constitui um sistema semiótico social robusto, que potencialmente expressa toda a gama de questões sociais em uma determinada comunidade; (b) os significados das variáveis ​​são subespecificados, ganham significados mais específicos no contexto dos estilos; e (c) a variação não apenas reflete, mas também constrói o significado social e, portanto, é uma força na mudança social.
Os Registros de Representação Semiótica e a Teoria De Conjuntos: uma análise de um capítulo de um livro didático.
Authors: Boneli Velten Mateus , Henrique Gualandi Jorge
Published: July 2022

Os diversos tipos de representação semiótica são de grande relevância para compreender o desenvolvimento cognitivo dos sujeitos no que concerne à apropriação dos saberes matemáticos. Assim, as diferentes representações de um objeto matemático possibilitam a resolução e a comunicação de resultados obtidos em uma atividade. Para tanto, levanta-se a seguinte problematização: como são apresentados os diversos tipos de representações semióticas no capítulo de conjuntos de um livro didático (LD). Para responder a essa questão, buscou-se investigar como os registros de representação semiótica (RRS) são articulados no decorrer do capítulo de conjuntos de um LD e se essas coordenações proporcionam a conversão ou tratamento. Esta pesquisa é de abordagem qualitativa pela interpretação de Bogdan e Biklen, ancorada na análise documental, como processo de coleta de informação, na acepção de Tozoni- Reis. Dessa forma, buscou-se analisar o capítulo de conjuntos de um LD, obra aprovada pelo Programa Nacional do Livro Didático (PNLD) 2021. O referido capítulo foi analisado à luz da Teoria dos Registros de Representação Semiótica (TRRS), de Raymond Duval. Ao final dessa análise, constatou-se que o capítulo de conjuntos articula vários tipos de RRS e estes proporcionam a coordenação entre registros, bem como a conversão. Por fim, conclui-se que, apesar de o capítulo analisado proporcionar a coordenação entre registros, é necessário que os estudantes sejam estimulados a explorar mais de um registro de representação, fazendo, sempre que conveniente, a conversão de um registro em outro.

Cost-efficient population genomic investigation of Daphnia longispina complex resting eggs using whole genome amplification and pre-sequencing screening
Authors: Nickel Jana , Cordellier Mathilde
Published: July 2022

Resting stages of aquatic organisms that accumulate in the sediment over
time are an exceptional resource that allows direct insights into past
populations and addressing evolutionary questions. This is of particular
interest in taxa that have recently faced environmental changes such as
the Daphnia longispina species complex, a keystone zooplankton
group in European freshwater ecosystems. However, genomic analysis might
be challenging as many of these resting stages are very small and the
DNA might be degraded. To reliably allow the resequencing of single
Daphnia resting eggs from different sediment layers and
characterize genomic changes through time, we performed whole genome
amplification to obtain DNA amounts suitable for genome re-sequencing
and tested multiple protocols involving egg isolation, whole genome
amplification kits and library preparation. A pre-sequencing
contamination screening was developed to quickly assess possible
contamination. In total, we successfully amplified and sequenced nine
genomes from Daphnia resting eggs that could be identified as
Daphnia longispina species. We analyzed the genome coverage and
SNP calling of these samples to optimize this method for future projects
involving population genomic investigation of the resting egg bank.
PRACTICE OF L-ASPARAGINASE USAGE: A SURVEY AMONG HEALTHCARE PROVIDERS TREATING CHILDREN WITH CANCER IN INDIA
Authors: MV Archana , Vijayasekharan Kalasekhar , Munikoty Vinay , R Ramitha Bhat , Achyutrao Atul , R Vani Lakshmi , K Vasudeva
Published: July 2022

Introduction: L‑Asparaginase is an essential chemotherapeutic
agent in the therapy of Acute Lymphoblastic Leukemia (ALL), which has
led to improvement in survival. In low and middle-income countries like
India, the outcomes in ALL are inferior compared to the published
literature, one of the cause of which are believed to be due to the
inferior quality of bioequivalent Asparaginase. The following survey
attempts to understand the practice of using this agent among
oncologists treating children with cancer in our country.
Methods: The researchers designed a structured online
questionnaire comprising 25 aspects of L-Asparaginase usage in the
study. The questionnaire was directed to the healthcare providers
involved in treating children with cancer in India. Results: Of
the total 80 responses recorded, 51 (64%) respondents had more than
five years of experience in pediatric oncology and were treating at
least 5-10 newly diagnosed ALL patients per month. Forty-one (51%)
respondents utilized Native Asparaginase, and 21 (26.3%) oncologists
used PEGylated-Asparaginase exclusively. The most common route of
administration was the intramuscular route (66.3%). Seventy percent of
respondents utilized Native form at a dose of 10,000IU/m
and 20% at 6000IU/m . The
amounts used for PEGylated L-Asparaginase were 1000IU/m
, 2500IU/m , and variable doses in
48%, 40%, and 10% of responses, respectively. Though Serum
Asparaginase assay (SAA) was not measured routinely in most of the
centres, 39 (48.8%) healthcare providers perceived performing SAA helps
to make the clinical decision. Conclusion: This survey shows a
wide variation in L-Asparaginase usage among healthcare providers caring
for children with cancer in our country. As L-Asparaginase is the
pivotal component of ALL therapy, uniformity in its usage and dosing
with the possibility of monitoring SAA due to the quality of
bioequivalent may be one of the critical steps towards improving
outcomes in ALL in our country.
Multiplex signal cascade fluorescent biosensing for single nucleotide polymorphisms enhanced detection
Authors: Li Shenghui , Yan Huan , Li Wenna , Peng Weipan , Gong Xiaoqun
Published: July 2022

Glioma seriously endangers human lives and health, and precise SNPs
genotyping is the key to modern clinical theranostics. A single nucleic
acid signal amplification strategy cannot effectively ensure sensitivity
and specificity detection. Herein, a multiplex signal amplification
platform based on collaborative chain reaction (LCR, HCR) and cascaded
rolling circle reaction (RCA) was first presented for specific and
sensitive single nucleotide polymorphisms (SNPs) enhanced genotyping.
The elongation HCR products were G-quadruplex and enriched on the
magnetic nanoparticles (MBs). As the fluorescent intercalator, the
thioflavin T (ThT) ligand was significantly embedded G-quadruplex
structure for fluorescence enhancement, to indicate the mutation
occurrence. Making use of the multiplex signal amplification strategy,
as low as 1×10 mol/L mutated strands can be
detected, and the allele frequency determined was accurately achieved at
0.5%, indicating high sensitivity and high fidelity. Furthermore, this
portable LCR-HCR-RCA multiplex signal cascade fluorescent biosensing
(LHRCA) was combined with the efficient enrichment and rapid separation
of magnetic nanoparticles (MBs), and suitable for glioma cell lysate
samples analysis, making it a promising candidate for disease-associated
SNPs discrimination.
Cycloxygenase-2 activates EGFR – ERK1/2 pathway via PGE2 mediated ADAM-17 signaling in testosterone-induced benign prostatic hyperplasia
Authors: Hammoda Mohammed Aboul Fotouh , Mohammed Maha , Mohamed Wafaa , Ramadan Laila , Afify Hassan
Published: July 2022

Background and Purpose: One of the most bothersome disorders affecting
elderly men is benign prostatic hyperplasia (BPH). Prostatic
inflammation is the driving force behind hyperplasia. A pro-inflammatory
response in the prostate has been linked to a number of cytokines and
growth factors. The current study evaluated the association between
inflammation and hyperplasia in BPH. Experimental Approach: A standard
selective COX-2 inhibitor; Celecoxib (CXB) (10 and 20 mg/kg) was
injected i.p. daily into male Wister rats for three weeks. From the
second week, testosterone (TST) (3 mg/kg) was injected s.c. daily to
induce BPH. Key Results: In TST-treated rats, there was a marked
increase in COX-2, concurrently with an elevation in prostate weight and
index as well. Moreover, TST-induced COX-2 was elucidated by the
deleterious changes in histopathological cytoskeleton. In addition,
overexpression of PGE2 , NF-κB (p65) , and IL-6 could be attributed to
COX-2 induced by TST. Additionally, COX-2-derived PGE2 increased the
activity of ADAM-17 , TGF-α , and TNF-α . Consequently, EGFR –ERK1/2
pathway was activated. Collectively, the normal balance between
prostatic cell proliferation (Bcl-2 and Cyclin D1) and apoptosis (Bax )
was disrupted. By using CXB, the effects of TST-induced COX-2 were
reversed. Conclusion and Implications: It can be concluded that COX-2 is
critical for overactivation of EGFR–ERK1/2 pathway in TST-induced BPH.
Concisely, COX-2 induces ERK1/2 pathway via PGE2–ADAM-17 catalyzed
shedding of TGF-α in TST-induced BPH. In addition, the present work
augments the functional correlation between inflammation and hyperplasia
in BPH.
Hot deformation behavior of micro-alloyed steel using processing maps developed with different constitutive equations
Authors: Thakur S.K. , Das A.K. , Jha B.K.
Published: July 2022

The hot workability of microalloyed steel was studied in the deformation temperature range of 850?1200?C and strain rate of 0.001-100s-1. The constitutive relation of flow stress with temperature, strain rate and strain was established to construct processing maps of the microalloyed steel. The processing maps were constructed using conventional power law, integral method, and Arrhenius equations. The developed processing maps were used to predict the optimal hot deformation conditions and were validated with metallurgical examinations. The safe regime for hot working of the experimental steel was found to be in the intermediate temperature-strain rate range (1000-1150?C;0.001-10 s-1), where the deformation process was dominated by dynamic recrystallization and dynamic recovery of the austenitic phase. The processing map constructed using Arrhenius equations increased continuously with an increase in deformation temperature and decrease in strain rate and it did not reveal relevant information of hot workability with respect to deformation temperature and strain rate. The dynamic recrystallization behavior of experimental steel was affected by both deformation temperature and strain rate which was explained in detail through microstructural examination.
Experimental and simulation study on bifacial photovoltaic modules integration with buildings
Authors: Chen Haifei , Wang Yunjie , Yang Huihan , Shi Yuanqing , Yu Bendong , Yang Jie
Published: July 2022

Compared with monofacial photovoltaic, bifacial photovoltaic modules can ab-sorb the irradiance on both sides, thereby obtaining more electricity revenue, which can meet more demands. In order to further improve the electrical efficiency of bifacial photovoltaic, this paper proposes a bifacial photovoltaic module with adjustable inclination for simulation and experimental research, which can be well combined with architecture. Under the conditions of different inclination, orientations and heights, the output performance of the bifacial photovoltaic module is analyzed. Under the best inclination, the annual electrical energy of bifacial photovoltaic is about 9.4% higher than that of monofacial photovoltaic. When the spacing between the bifacial photovoltaic and the wall is 1-1.5 times the size of the photovoltaic, the electrical energy will increase the most. Considering the influence of wall color on bifacial photovoltaic performance, the photovoltaic electrical energy under the white wall can reach up to 35% higher than that with respect to the concrete color (dark grey).

Authors: Natarajan Anbazhaghan , Venugopal Dillibabu , Thangavelu Lakshmanan
Published: July 2022

The syngas produced from gasification process is used for many applications: the selection of fuel, gasifying medium, and operating condition has major influence on the final gas composition. In the present work, rice husk air gasification, rice husk steam gasification, sawdust air gasification and sawdust oxygen gasification simulation were carried out by non-stoichiometric equilibrium model based on Gibbs free energy minimization using FACTSAGE 6.3 software. The investigation is carried out to study the effect of operating conditions on biomass gasification. In rice husk air gasification, increase in temperature enhances H2 value at equivalence ratio ? = 0.25, at other ? values after reaching optimum value H2 formation decreases. In sawdust oxygen gasification, increase in ? value enhances CO2 formation for all temperatures and increase in temperature reduces CO2 formation for all ? value. Increase in equivalence ratio for all the temperatures decreases the combustible gases formation due to the oxidation reactions. Gas compositions were compared to study the effect of fuel quality and gasifying medium on the gasification process. Rice husk air gasification has 5.85% higher CO formation than sawdust air gasification at 800?C and ? = 0.45. The maximum difference of 13.8% was observed for H2 content at 700?C and ? = 0.45 between sawdust air and oxygen gasification. Gas heating value and gasification efficiency were determined for the biomass gasification processes.
Experimental study on boiling heat transfer in negative-pressure flowing water in a vertical annular tube
Authors: Guo Jiachao , Wang Shaohua , Jin Lei , Tian Xiaoliang
Published: July 2022

To study energy recovery from low temperature wastewater during industrial production, a water-boiling heat transfer experimental device was built. A casing evaporator with a length of 1450 mm, an inner tube diameter of 30 mm, and an annular space gap of 14.2 mm is taken as the main research object. The boiling heat transfer characteristics of water in the annular tube area of the casing evaporator were experimentally studied by adjusting the inlet temperature (60? 85?C) of hot water and the pressure in the annular tube (12.1-57.6 kPa). The results show that, as the pressure of the system decreases, the boiling phenomenon in the annular tube becomes more intense and the convective heat transfer coeffi-cient increases. The boiling flow and average surface convective heat transfer enhancement rates, ? , were 2.2 and 1.5 when an initial pressure of 1 kPa was used. When the flow rate of the working medium in the annular tube was 1.69 kg?m2/s, the convective heat transfer coefficient gradually increased with the temperature and then stabilized when the inlet temperature reached between 80?C and 85?C. These results reveal the characteristics of boiling-water heat transfer in an annular tube and aid in the design of heat pipe systems for waste-heat recovery.

Authors: Bayhan Burhan , Arslan Gokhan
Published: July 2022

The most commonplace natural flow inside one-ended inclined pipes today is water heating systems. In this study, a model was created for the estimation of the pipe outlet temperature of the fluid with the energy balance for the inside of the tank, flow rate calculation of natural circulation, and other thermal calculations in a one-ended inclined pipe. In addition, this model has been compared with the Li model in the literature, and it is easier and more successful. 100 W, 200 W, 400 W, 600 W, and 800 W thermal power was applied to a one-ended inclined pipe, and the temperature values were recorded in five minute periods in the experiments that lasted a total of six hours. As the average of the experiments, the estimation results for the current model and the Li model are: the average per-cent relative error rates are 6.02 and 15.1 and the coefficient of determination, R2, are 0.9865 and 0.9683, respectively.
Ann Hopkins and PwC: Critically Analyzing Culture, Leadership, Policies, and Reporting for Diversity and Inclusion
Authors: Campbell Katherine , Helleloid Duane
Published: July 2022

Large public accounting firms are currently prioritizing diversity and inclusion and making commitments to increased transparency by publishing diversity, equity, and inclusion reports. This case explores PwC’s self-described diversity and inclusion journey by juxtaposing the firm’s first publicly released diversity and inclusion report with the decades-earlier experience of Ann Hopkins, who became a partner as the result of a landmark Supreme Court case. This approach provides a longitudinal perspective on diversity and inclusion and facilitates analysis of the roles of organizational policies/procedures, organizational culture, and leadership in creating a more inclusive organization. The case presents an opportunity to analyze PwC’s published diversity data and explore the challenges firms face when trying to increase diversity and develop an inclusive culture.
Exercise-linked skeletal irisin ameliorates diabetes-associated osteoporosis by inhibiting the oxidative damage-dependent miR-150-FNDC5/pyroptosis axis
Authors: Behera Jyotirmaya , Ison Jessica , Voor Michael J. , Tyagi , Neetu , Tyagi Neetu
Published: July 2022

  

Recent evidence suggests that physical exercise (EX) promotes skeletal development. However, the impact of EX on the progression of bone loss and deterioration of mechanical strength in type 2 diabetic (T2DM) mice remains unexplored. In the present study, we investigated the effect of EX on bone mass and mechanical quality using a diabetic mouse model. The T2DM mouse model was established by a high-fat diet (HFD) with two streptozotocin (STZ) injections (50 mg/kg/body weight) in C57BL/6 female mice. The diabetic mice underwent treadmill exercises (5 days/week at 7-11 m/min for 60 minutes per day) for 8 weeks. The data showed that diabetes upregulated miR-150 expression through an oxidative stress and suppressed FNDC5/irisin by binding to its 3’-UTR. The decreased level of irisin further triggers the pyroptosis response in diabetic bone tissue. EX or N-acetyl cysteine (NAC) or anti-miRNA-150 transfection in T2DM mice restored FNDC5/irisin expression and bone formation. Furthermore, EX or r-irisin administration prevented T2DM-induced hyperglycemia and improved glucose intolerance in diabetic mice. Furthermore, osteoblastic knockdown of Nlrp3 silencing (siNlrp3) or pyroptosis inhibitor (AYC) treatment restores bone mineralization in diabetic mice. Micro-CT scans and mechanical testing revealed that trabecular bone microarchitecture and bone mechanical properties were improved after EX in diabetic mice. Irisin, either induced by skeleton or daily EX or directly administered, prevents bone loss by mitigating inflammasome-associated pyroptosis signaling in diabetic mice. This study demonstrates that EX-induced skeletal irisin ameliorates diabetes-associated glucose intolerance and bone loss and possibly provides a mechanism of its effects on metabolic osteoporosis.
Lærarars djupnelæring i profesjonsfaglege utviklingsprosjekt
Authors: Fiskerstrand Pernille
Published: July 2022

Denne artikkelen diskuterer premissar for lærarars djupnelæring i profesjonsfaglege utviklingsprosjekt. Frå før veit vi at slike prosjekt bør gå over tid og helst vere lokaliserte på eigen arbeidsplass. Når lærarar skal lære, er det også ein føresetnad at dei får arbeide seg til forståing av teori, slik at kvardagserfaringar blir løfta til generaliserte vitskaplege omgrep. Erfaringar saman med fagspråk og refleksjonar kan då overførast som reiskap til bruk i nye samanhengar. Lærarars djupnelæring i profesjonsfaglege utviklingsprosjekt blir i denne artikkelen tematisert ved forskingsspørsmålet: «Korleis utviklar lærarar felles didaktisk metaspråk i eit profesjonsfagleg utviklingsprosjekt?» Funna frå undersøkinga blir løfta vidare inn i ein teoretisk diskusjon der premissar for djupnelæring blir sett opp mot lærarane si utvikling av felles didaktisk metaspråk. Data i casestudien er henta frå observasjon, intervju og innsamla dokument frå eit lesson study-prosjekt gjennomført på VG1. Materialet er analysert ved ein innhaldsanalyse der bruk og samhandling av fagdidaktiske omgrep er studert. Artikkelen konkluderer med at lærarane utviklar eit felles didaktisk metaspråk gjennom arbeidet med LS-prosjektet. Premissane for djupnelæring er dermed til stades. Samtidig er der kritiske rammefaktorar som utfordrar denne djupnelæringa.
Teachers’ in-depth learning in professional development projects
This article discusses various premises for teachers’ in-depth learning in projects for professional development. We already know that such projects should run over time and take place at the school where the teachers work. When teachers are learning, it is a pre-requisite that they get to develop theoretical understanding, so that the everyday language of teaching can be transformed and articulated in more general scientific terms. Experience, together with reflections and theoretical concepts, can then be transferred as tools to use in new professional contexts. Teachers’ in-depth learning in professional development is here studied through the research question: “How do teachers develop a shared didactical metalanguage through participating in a professional development project?” In addition, the findings in the study are addressed in a theoretical discussion where premises for in-depth learning are considered in light of the teachers’ development of a shared didactical metalanguage. The data in the case-study is collected by observation, interviews, and collected documents in an Upper secondary, lesson-study project (VG1). The qualitative data is analysed through content analyses, which emphasizes the teachers’ use of different concepts and the relationship between them. The article concludes that the teachers developed a shared didactical throughout the LS-project, which implies premises for in-depth learning, although some critical frame factors challenge these learning processes.
DESIGN OF OCCUPATIONAL SAFETY TRAINING FOR SINGLE PARENTS OF WEDORO SIDOARJO SHOE WORKERS
Authors: Aulia Raiza
Published: July 2022

Work safety for workers is very important to be fulfilled in terms of complete personal protective equipment such as boots, and at least with the use of masks. This is important because the effects that arise when the use of personal protective equipment is not used properly can interfere with health. One of them is the shoe craftsman Wedoro Sidoarjo. This made the researchers make a training plan for single parents of shoe craftsmen in Wedoro Sidoarjo to pay more attention to work safety if not done with the right standards it will affect the children at home. The implementation of this training was made based on the results of interviews with the sole parent of shoe craftsman Wedoro Sidoarjo. This training can be done in groups. Implementation carried out in groups will look like real social life. The number of participants from group training should be no more than 16 people because the number of groups that are too large will result in the ineffectiveness of the training (Kelly, 1982; Michelson, et al. 1985; Ramdhani, 2015). This training was conducted at the Nur Rahma Sidoarjo Foundation by 16 single parents. Participants will be given knowledge about good parenting styles for children, knowing the principles of child development, and occupational health and safety. Each material provided will include games, roleplay, and watching movies.

GeoGebra para el aprendizaje de modelación matemática en ingeniería: estudio de caso (modalidad en línea)
Authors: Gaona Jiménez Silvia Melbi , Guerrero Ramírez Sandra Luz
Published: July 2022

En este estudio de caso, el objetivo fue contrastar cuantitativamente y cualitativamente el logro del aprendizaje de modelación matemática (adquisición de lenguaje formal, construcción del modelo, solución e interpretación del modelo y aplicación del modelo) entre un enfoque sistémico que recurre al uso del software GeoGebra y un enfoque convencional. Esta investigación tuvo un alcance mixto, descriptivo y parcialmente experimental. Se trabajó, en una modalidad en línea, con una muestra no probabilística de 130 estudiantes de ingeniería, segmentados en un grupo control y otro experimental. Respecto a los resultados obtenidos, se encontró que al final de las tres etapas del estudio, en una escala de 0 a 10, el grupo control logró un incremento en desempeño de 3.01 y que, habiendo transcurrido cuatro meses, se perdieron 1.95 puntos. Por su parte, el grupo experimental obtuvo un incremento en desempeño de 4.66 y después de cuatro meses tuvo una reducción de 0.94 puntos. El incremento real en desempeño de la etapa de diagnóstico al punto final fue de 1.06 para el grupo control y de 3.72 para el grupo experimental. En términos cuantitativos, esto representa una diferencia absoluta estadísticamente significativa entre el grupo control y el experimental de 26 puntos porcentuales, lo que equivale a una diferencia relativa de 250.94 % entre el diagnóstico y la etapa realizada a cuatro meses de la intervención. El incremento en desempeño fue mayor en el grupo experimental. Los resultados indican que el enfoque sistémico de aprendizaje propuesto asistido con GeoGebra pudiera incidir de forma positiva en el desempeño en modelado matemático.
Investigation of drying process kinetics of composite granules
Authors:   Institute of Engineering Thermophysics of NAS of Ukraine, Petrova Zhanna
Published: July 2022

Among the large number of modern environmental problems in Ukraine, waste of wastewater treatment stations occupies a special place. During biological water treatment, the separated sludge deposits are sent to the silt fields, which are the biggest problem. Today, these fields reached their capacity three times over and pose a danger, the consequences of which go far beyond environmental problems and have grown into a chain of socio-economic, technical, medical-biological and moral-ethical problems. Previously, activated sludge was used as fertilizer in the fields, but in connection with the Chornobyl Disaster, it was banned. As a result, accumulations of silt deposits were formed, which are also called obsolete. A modern solution is the compaction of sediments and the development of energy-efficient technologies for the processing of obsolete sludge and incineration in appropriate facilities. This paper presents the results of the drying process study for composite granules based on peat, sludge and biomass. The effect of coolant temperature on the drying rate shows the 1.4-fold intensification of the drying process. Theoretical studies with the construction of generalized drying curves of composite granules calculated by the method of V. V. Krasnikov showed coincidence with experimental data.

A phenomenon has been singled out that is present during almost every shot. It manifests itself in a muzzle blast in the form of soot of a certain amount. The Bell-Boudoir thermochemical reaction has been defined, which explains the formation of soot in powder gases during the shot. The conditions making it possible to manifest have been mentioned. A method for solving the problem of internal ballistics has been developed, enabling to determine the temperature of powder gases along the length of the gun barrel at different times and at different positions of the projectile in the barrel. The modelling of the powder gases temperature distribution in the barrel space between the charging chamber and the moving projectile has been carried out in the model system. The possibility of changing the length of the zone of the Bell-Boudoir reaction (the zone of soot formation) depending on the initial data has been shown. The use of a fresh powder charge and a degraded one has been modelled.
