Published: February 2022

Estalki putzuduna klima lehorreko herrialdeetan erabili ohi da. Horregatik, ez da kasualitatea estalki horren inguruko ikerketa garrantzitsuenak Indian, AEBn eta Israelen eginak izatea. Hala ere, pasa den mendean, estalki putzuduna asko hedatu zen Euskal Herriko eraikinetan, gehienbat ingurune industrialetan. Gaur egun, ordea, ia ez da erabiltzen. Zergatik erabili zen hainbeste estalki putzuduna gure herrialdean, hain hezea izanik? Artikulu honetan, galdera horri erantzuten saiatu gara, estalki putzudunaren ezaugarriak, abantailak eta arazoak jorratuz. Hasteko, estalkien hainbat sailkapen aurkezten ditugu, estalki putzudunaren ezaugarriak hobeto ulertzeko. Estalki putzudunaren historia laburki lantzen dugu, Euskal Herriko —eta, bereziki, Arrasateko— adibideetan jarriz arreta. Estalki putzudunak abantaila garrantzitsuak ditu eraikinaren kudeaketa termiko pasiboa hobetzeko. Alde batetik, eraikinaren inertzia eta isolamendu termikoa areagotu egiten dira, barruko bizi-giroa hobetuz. Beste aldetik, eraikina hoztu edo berotu egin daiteke, estalki putzuduna erabiltzen duten hainbat metodoz baliatuz. Estalki putzudunak bestelako abantailak ere eskaintzen ditu, hala nola jasangarria dela eta ikuspegi ekologikotik onurak besterik ez dituela. Eta, noski, desabantaila batzuk ere baditu: zikinkeria pila daiteke, mantentze-lana eskatzen du eta eraikinaren egiturak sendoagoa izan behar du, uraren zama jasateko. Amaitzeko, nazioarteko hainbat adibide aurkezten ditugu, estalki putzudunaren gaur egungo erabilerak ezagutarazteko. Laburbilduz, arazo batzuk baditu ere, estalki putzuduna interesgarria da oraindik, eta gaur egungo eraikinetan eta Euskal Herriko eraikin batzuetan onuragarria izan liteke.
Euskal Autonomia Erkidegoan kokatuta dauden eraikinen birgaitze energetikoa: Birgaitze-teknikak eta erabakia hartzeko jasangarritasun-irizpideak.

Published: February 2022

Eraikuntzako energia-kontsumoak gora egin du azken urteotan. Horregatik, eraikinen energia-eraginkortasunari buruzko araudiak ezarri behar izan dira kontsumoa kontrolatzeko, energia-aurrezpena hobetzeko eta energia-eraginkortasuna hobetzeko. Baina Euskal Autonomia Erkidegoan zaharrak eta energetikoki pobreak diren eraikin kopurua oso altua denez, behar beharrezkoa da eraikin horietan esku hartzea eta epe labur edo ertainean energetikoki birgaitzea.
Birgaitze-teknikarik egokiena aukeratzea ez da lan erreza eraikinak energetikoki birgaitzeko eraikuntza-soluzio ugari baitaude. Hau dela eta, erabakia hartzen laguntzeko, jasangarritasun-irizpideak erabiltzea planteatzen da. Horrela, birgaitze-teknikak ekonomiaren, ingurumenaren eta sozialaren ikuspegitik aztertuko dira.
Harea berdeen erabilera morteroen eroankortasun termikoa aldatzeko

Published: February 2022

Eraikuntza-sektorean hormigoiak eta morteroak dira gehien erabiltzen diren eraikuntza-materialak, eta lehengai natural asko kontsumitzen dituzte, beren osagai nagusiak (harea eta zementua) harrobietatik lortutako harri naturalak tratatuz lortu behar baitira. Baliabide naturalen erabilera murrizteko helburuarekin, morteroetan galdaketako harea birziklatua erabiltzeak propietate fisiko, termiko eta mekanikoetan duen eragina aztertzen da artikulu honetan. Morteroetan normalean erabiltzen den kareharri-harearen ordez, galdaketako harea berdea erabili da, hainbat ehunekotan (% 0, % 25, % 50, % 75 eta % 100), eta mortero gogortuen porositatea, ultrasoinuen hedapen abiadura, eroankortasun termikoa, bero espezifiko bolumetrikoa, eta makurdura- eta konpresio-erresistentziak neurtu dira. Emaitzak aztertuta, argi dago galdaketako harea berdeak duen bentonita-edukiaren eragina: ur gehiago behar duenez, handitu egiten du porositatea, eta murriztu egiten ditu eroankortasun termikoa, bero espezifiko bolumetrikoa eta erresistentzia. Hala ere, galdaketako harea berdearen erabilera bideragarria litzateke exijitu beharreko erresistentzia mekanikoa baxua denean eta morteroaren eroankortasun termikoa murriztea interesgarria denean. Adibidez, zolatu eta estalkietan erabil liteke, nibelatze-kapa moduan.

Published: February 2022

Lan honetan altzairu-egur petral hibrido (steel-wood purlings, SWP) baten egiturazko tipologia berri bat aurkezten da, CF (cold-formed) motako hotzeko konformazio altzairuz eta egur laminatu errektangularrez osatua. Horrela, egurrezko petralak altzairuzko zati batzuekin indartuz, hobekuntza nabarmenak lortzen dira zabalduen dauden altzairuzko petralekiko. Egurrezko sekzioa ahulagoa izan arren eta altzairuak baino modulu elastiko baxuagoa duen arren, SWPren dimentsioa ez da CF motako altzairuzko petralarena baino handiagoa izango. Altzairuzkoen aldean, SWP petralek mantenu-lan gutxiago dutenez eta arinagoak direnez, eraikinaren egitura nagusiak ere material gutxiago beharko du. Material bakoitzak egituran duen disposizioaren arabera portaera mekanikoan duen eragina aztertzen da, argia eta diseinu karga aintzat hartuta. Horretarako, tentsio normala eta geziaren diseinu-irizpideak aztertzen dira argi bakoitzean material bakoitzaren luzeraren arabera. SWPren kalkuluan hurbilpen analitikoa erabili da, zeinak bete egiten baitituen diseinu-eskakizun teknikoak.
Chronic pancreatitis is a risk factor for pancreatic cancer and incidence increases with duration of disease: A systematic review and meta-analysis
Authors: Gandhi Sonal , Fuente Jaime de la , Murad Mohammad Hassan , Majumder Shounak
Published: February 2022

Background:

Observational studies have suggested an increased risk of pancreatic ductal adenocarcinoma (PDAC) in patients with acute and chronic pancreatitis. We conducted a systematic review and meta-analysis to evaluate the magnitude of this association and summarize the published epidemiological evidence.

Methods:

We searched electronic databases (MEDLINE, EMBASE, Web of Science, Cochrane, Scopus) and reference lists until January 18, 2021. Studies reporting quantitative association between pancreatitis and PDAC were included and assessed for eligibility, data abstraction, and risk of bias. Standardized incidence ratios (SIR) were pooled using the random-effects model.

Results:

Twenty-five cohort and case-control studies met inclusion criteria. Meta-analysis of 12 chronic pancreatitis (CP) studies demonstrated an increased risk of PDAC in CP patients (SIR: 22.61, 95% confidence interval [CI]: 14.42-35.44). This elevated risk persisted in subgroup analysis of studies that excluded patients diagnosed with PDAC within 2 years of CP diagnosis (SIR: 21.77, 95% CI: 14.43-32.720). The risk was higher in hereditary pancreatitis (HP) (SIR: 63.36, 95% CI: 45.39-88.46). The cumulative incidence rates of PDAC in CP increased with follow up duration. Limited evidence in acute pancreatitis indicates higher PDAC risk in the subset of patients eventually diagnosed with CP. PDAC appears to be uncommon in patients with autoimmune pancreatitis, with 8 reported cases in 358 autoimmune pancreatitis patients across 4 studies.

Discussion:

There is an increased risk of PDAC in patients with CP and incidence rates increase with CP disease duration. Our results indicate that PDAC surveillance may be considered in individuals with long-standing CP.
New Model, Same Old Stories?
Authors: Nowak Raphaël , Morgan Benjamin A.
Published: February 2022

At the turn of the 2020s, music is largely distributed and consumed via streaming services. This new »moment« in recorded music has attracted a lot of attention from scholars, with the aim of identifying the nature of transformations that are occurring at an economic and/or cultural level. This chapter critically assesses scholarly analyses of music production, distribution, and consumption in the age of streaming services. We note that accounts tend to work with specific assumptions underpinning the association between culture and technology, in particular in relation to the democratization of access. We argue in this chapter that music streaming services become a leitmotiv to anchor discourses about what music should ideally be, thus reproducing narratives that predate the emergence of music streaming.
The National Society of Music (1915-1922) and the Ambivalent Democratization of Music in Spain
Authors: Ferreiro Carballo David
Published: February 2022

The Spanish National Society of Music was founded in 1915 with a double objective: first, to define, once and for all, the musical identity of the country; and second, to create a space where composers and musicians could develop their artistic careers. In this sense, both the society's self-denomination as »national,« and its apparent integrating nature suggest a clear attempt to democratize Spanish music. However, the present paper shows that the reality was completely different. Yet, by analyzing the society's internal ideology, by describing its policy for selecting the repertoire of the concerts, and by examining its actual social impact, David Ferreiro Carballo demonstrates that the National Society of Music was a non-democratic institution with an elitist understanding of the art. This reality strongly contrasts its typically idealized conception and will allow the reader to understand its disappearance in 1922, after only seven seasons of activity.
The Intervision Song Contest
Authors: Vuletic Dean
Published: February 2022

During the Cold War, Eastern Bloc broadcasting organizations held the Intervision Song Contest (ISC) as an alternative to Western Europe's Eurovision Song Contest (ESC). Staged in Czechoslovakia and Poland between 1964 and 1980, the ISC has usually been depicted in the popular media as merely a belated, fleeting copy of the ESC, with the ISC's failure being a metaphor for the decline of the economic and political systems of communist party-led Eastern Europe. However, unlike with the ESC, there has been little academic research on the ISC. This chapter is based on archival sources from national and international broadcasting organizations, and focuses on the first series of the ISC in Czechoslovakia. It argues that the ISC was conceived by its organizers as a pan-European event that would promote cooperation between the Eastern and Western blocs, especially in the context of Khrushchev's Thaw and the cultural and political liberalization in Czechoslovakia that culminated in the Prague Spring. The ISC's organizers accordingly introduced innovations that made their contest more internationally open and commercial than the ESC. Furthermore, the staging of the ISC in Czechoslovakia underlined the limits of the Soviet Union's cultural and political influence over Eastern Europe and the role that geopolitics played in the power relations between states within the Eastern Bloc. The ISC was, then, not simply an imitation of the ESC, but rather a product of international political relations that tells us much about the aspirations that some Eastern European artists, politicians, and officials from record companies and television stations had for the democratization of their states.
Expanding Musical Inclusivity
Authors: Best Katelyn
Published: February 2022

Products such as headphones, music streaming platforms, and learning assessments foster a hearing-centric realization of music that places auditory senses at the forefront of musical experience. Yet within the context of Deaf culture, a linguistic minority defined by the use of sign language, music takes on new meaning as musical experience is expanded to other senses of the body. Despite this relative construction, music in Deaf culture has been subjugated to a hegemonic ideology that undermines and marginalizes Deaf experiences of sound. However, Deaf musicians have been able to work toward subverting the ideological limitations that have been placed on their music, and by extension their bodies, by adapting musical structures produced by mainstream society and realigning them toward Deaf priorities. Using ethnographic methods including artist interviews, this chapter investigates how Deaf rappers have created a style of hip hop that prioritizes Deaf experiences of sound over hearing ones and considers how, through performance, they subvert hegemonic control over Deaf musical expression and promote the inclusion of Deaf forms of musicking.

Naming rigths: receita complementar nos contratos de parcerias público-privadas ou cessão de uso de bens públicos sem licitação?
Authors: Gullo Felipe Ramirez
Published: February 2022

O Estado tem a função de prestar serviços públicos para assegurar a promoção dos direitos fundamentais, contudo não dispõe de recursos para atender integralmente as necessidades da sociedade. Uma das soluções criada no Brasil para este problema foi o modelo das parcerias público-privadas (PPPs), sendo definido como contrato de longo prazo de duração em que se atribui ao parceiro privado o dever de executar obra pública e prestar serviço público mediante remuneração, que poderá ser por diversos meios, mediante garantia especial. A pergunta do presente artigo é se uma concessionária pode, através da utilização do instituto de receitas alternativas dispostas no contrato de parcerias público-privadas, conceder os direitos à denominação (naming rigths) de um bem público no qual presta seu serviço.
Defensa de la presunción de inocencia como garantía esencial en el derecho administrativo sancionador
Authors: Alejos Guzmán Oscar Alberto
Published: February 2022

En un reciente artículo se ha propuesto invertir la carga de la prueba en el procedimiento sancionador, de manera que sea el administrado quien demuestre su inocencia. Esta nueva regla se utilizaría en aquellos casos en donde es menos costoso para el administrado producir la prueba necesaria para exonerarse de responsabilidad. De esta forma, se enfrentaría el problema de la conducta estratégica que podría tener el administrado para ocultar información. En el presente artículo, se analiza críticamente la propuesta mencionada, cuestionando sus bases teóricas y sus implicancias prácticas. En otras palabras, se asume una defensa de la garantía constitucional de presunción de inocencia, la misma que, en la posición del autor, no admite ni debe admitir excepciones.
Religious Engagement within Refugee Resettlement in Canada: Lessons to Learn
Authors: Izzul Haq Muhammad
Published: February 2022

In recent years, Canada has become a global leader in refugees and the top world leader in refugee resettlement. Direct participation by civil society, mainly dominated by the religious congregation and faith-based organizations in resettlement, has been the hallmark of Canada's private sponsorship program and a significant element in its success.  This paper explores the evidence base of existing literature covering religious engagement within Canada's umbrella of refugee resettlement. Religious engagement is exemplified by the involvement of religious groups, congregations or communities in refugee resettlement which defines and shapes this policy, particularly in the private refugee sponsorship program.  Despite challenges shadowing the process, religious engagement contributes to more outcomes given its potential social capital. It is predicted that religious groups will continue to be leading actors within Canada’s resettlement programs.
Community Empowerment through Village-Owned Enterprises Activities as a Regional Development Strategy in Indonesia: A Systematic Literature Review
Authors: Lestary Riska Ayu , Hadi Krishno
Published: February 2022

This study aims to determine community empowerment that can be done through the Village-Owned Enterprises (Badan Usaha Milik Desa/BUMDes) program to support village income. Problems related to disparities in villages in areas that require a development strategy through empowerment programs, require the role of government and society in carrying it out. The type of research of this article uses the literature review method which comes from previous research indexed by the Scopus Database and processed in the Vosviewer application. In this study, it is revealed that the role of BUMDes can increase village income and prosper the village community, and then it can support development in the region. The role of rural communities is very much needed for regional development efforts; especially during the COVID-19 pandemic the existence of BUMDes can increase the country's economy which had experienced a decline. The main key in increasing BUMDes as a regional development strategy is through increasing community participation.
Phenological documentation of Lantana camara L. using modified BBCH scale in relation to climatic variables
Authors: Kumar Abhishek , Singh Sanjay , Chand Harish Bahadur , Kumar Rahul
Published: February 2022

Lantana camara L. (Verbenaceae) is cultivated as an ornamental and hedge plant in many countries which is native to American tropics. It’s introduction to the Indian subcontinent dates back around 200 years ago. It is an invasive alien species that has a negative impact on native biodiversity. It is evident that management of L. camara is crucial for the conservation of biodiversity. Studying its phenological characteristics as they adapt to environmental circumstances through time and space will aid in the development of management goals and strategies. This study uses BBCH scale firstly to describe the phenology of L. camara, which is represented by nine Phenological Growth Stages (PGS) in response to environmental conditions during a 32-month period in Dehradun, Uttarakhand, representing its growth. To standardise morphological traits and the phenological observation, photographs of certain significant developmental stages on L. camara in addition to the descriptions have been illustrated. Researchers can utilise this uniform labelling method as a tool to help with weed management efforts. Phenological studies of this invasive weed species may be employed for tracking the gradual impact of climate change on biodiversity and its effect on the key phenological events in the lifecycle.
Self-identity construction and pragmatic compensation in a Chinese DAT elder’s discourse
Authors: Huang Lihe , Zhu Qi , Zhou Deyu
Published: February 2022

This study explores how the identity is constructed of elders who have Dementia of the Alzheimer Type (DAT) by examining the communicative disorder in daily interactions with other interlocutors. Specifically, this paper evaluates a conversation between one Chinese elder with early-stage DAT and the interviewer. It analyzes the identity construction processes in the discourse in depth, using the age-identity taxonomy, self-identity representation theory, and the pragmatic emergentist model. Based on the case study, this paper confirms the five dimensions of age-identity taxonomy provided by Coupland as: (1) disclosure of chronological age, (2) age-related categories/role reference, (3) age-identity concerning health, decrement, and death, (4) adding time-past perspective, and (5) self-association with the past. Meanwhile, two more approaches to the age-identity taxonomy were developed, i.e., address behavior and cross-generational contrast. Self-identity to realize interactional goals is typically constructed at the individual level, although rarely at the relational level. The DAT elder conducts compensation in the interaction by adopting verbal and non-verbal strategies to bridge cognitive disorders such as memory loss, word-finding difficulty, or meeting the desire to enhance the pragmatic effects of their identity. This shows that the self-identity construction also facilitates the DAT elders in generating a discourse strategy when encountering pragmatic impairment.

Numerical and experimental research on solidification of T2 copper alloy during the twin-roll casting
Authors: Lv Zheng , Sun Zhen-Jun , Hou Zhi-Hui , Yang Zhou-Yi , Zhang Xi-Liang , Shi Yin-Dong
Published: February 2022

Based on CAFE theory and KGT model, the twin-roll strip casting mathematical model was established to solve the dendrite growth and solidification of T2 copper alloy in the molten pool. The influence mechanism of casting temperature, heat transfer, and other technological conditions on the microstructure of strip was analyzed. The results showed that the liquid metal formed 35 µm chilling layer after touching the rollers, and the layer was consisted of a high number of small and equiaxed crystals. Then some grains would appear close to the newly chilling layer, and grow toward the core of molten pool competitively. The dominant grains mainly grew along the 〈001〉 orientation into columnar crystals, and the rest grains that grew out of alignment were eliminated gradually. The number of grains declined, and the radius of columnar grains became coarsening. The Kiss point is a key factor for solidification structure, and the lower location of the Kiss point could limit the growth spaces of columnar crystals, which refined the grains.
Size effects in the plastic deformation of NiAl thin films
Authors: Wellner P. , Dehm G. , Kraft O. , Arzt E.
Published: February 2022

This paper presents the first study of the plastic behavior of NiAl thin films with thicknesses in the micron and sub-micron range. The influence of geometrical and microstructural constraints was studied for different Al contents (45 to 50 at.% Al) and film thicknesses (0.2 to 3.1 μm) in the temperature range from 20 to 700 °C. The films were deposited on Si substrates and subjected to temperature changes resulting in thermal strains of up to 0.84%. The stress evolution in the films was measured by the substrate curvature method. The residual stress at room temperature of nearstoichiometric NiAl films significantly increased with decreasing film thickness indicating an increase of the film strength. At temperatures above 400 °C strong stress relaxation was found, which was more pronounced in thinner films suggesting the contribution of diffusional creep processes. The existence of a critical film thickness is suggested at which a transition from diffusion-controlled to dislocation-controlled plasticity occurs. The results have potential implications for the reliability of NiAl films as protective coatings in thermal engines.
HVEM in situ study of fracture of Al2O3/Nb sandwich specimens
Authors: Messerschmidt Ulrich , Bartsch Martin , Dietzsch Christian , Kurtz Wolfgang , Scheu Christina , Rühle Manfred
Published: February 2022

In situ straining experiments on α-Al2O3/Nb/α-Al2O3 single crystal sandwiches have been performed in a high-voltage electron microscope in order to observe the dislocation motion connected with the fracture of these samples. The tricrystals had two different orientation relationships at the interfaces, both possessing high fracture energies. The in situ studies showed that the fracture occurs along the interfaces but more frequently inside the Nb sheet. The fracture is connected with strong plastic deformation. The crack opening and the dislocation processes are analysed.
Herausforderungen von Strafverfahren mit psychisch kranken Opfern – die psychosoziale Prozessbegleitung als möglicher Bewältigungsansatz? Ein Dialog mit Expertinnen und Experten
Authors: Lindemann Michael , Menke Janita , Frenser Katharina
Published: February 2022

Menschen mit einer psychischen Erkrankung weisen ein höheres Risiko auf, Opfer einer Straftat zu werden, als Personen ohne eine solche Erkrankung. Darüber hinaus spricht viel dafür, dass sie als besonders vulnerable Personengruppe vergleichsweise umfangreiche Unterstützung im Strafverfahren benötigen. Dies kann die in solchen Verfahren agierenden Berufsakteur:innen in allen Verfahrensstadien vor besondere Herausforderungen stellen. In einer an der Universität Bielefeld im Rahmen des Projekts „Viktimisierung, Recht und Opferschutz“ (kurz: ViReO) durchgeführten qualitativen Studie wurden Expert:innen zu ihren Erfahrungen mit Strafverfahren befragt, in welche schwer psychisch kranke Opferzeug:innen involviert waren. Dabei wurde unter anderem die psychosoziale Prozessbegleitung als eine Unterstützungsmöglichkeit für betroffene Opferzeug:innen und als Entlastung für Polizei und Justiz thematisiert.

Climate change, loss of biodiversity and degradation of ecosystems are all linked and have devastating consequences for our socio-economic stability, health and well-being. Working with nature is increasingly recognized as an efficient way to tackle these growing challenges, according to the new EEA report ‘Nature-based solutions in Europe: Policy, knowledge and practice for climate change adaptation and disaster risk reduction.’ In line with the basin wide updated flood risk strategy like International Commission for the Protection of the Danube River (hereafter: ICPDR) Flood Risk Management Plans 2021. Multilevel action plans have been developed. The EU level plans, such as the EU Strategy for the Danube Region, from the geographical point of view (for example: EU Green Deal) are mainly based on watersheds and on macro-regional scale. However, at the same time, counties should elaborate their strategies on their own level. Hungary has many strategies, one of the most relevant in terms of climate change is the Hungarian National Water Strategy (hereafter: HNWS), also known as, Kvassay Jenő Plan.
Velocity-Based Resistance Training in Soccer: Practical Applications and Technical Considerations
Authors: Hernández-Belmonte Alejandro , Alegre Luis M. , Courel-Ibáñez Javier
Published: February 2022

Since 2010, the velocity-based approach (VBT) has been established as a reliable method to be used during resistance training (RT) interventions. VBT lies in the monitoring of the barbell velocity during the concentric phase of an exercise, which is a direct consequence of the force applied by the athlete to the external load. VBT offers coaches and physical trainers of soccer teams a wide spectrum of practical applications. Considering the close association between the barbell velocity and the relative intensity (i.e., load-velocity relationship), practitioners could ensure “on the go” that players train very close to the programmed load in each training set. Methodologies derived from the VBT, such as the velocity loss or the “level of effort,” allow to plan and control the intraset fatigue to be incurred by the soccer players during RT. Incorporating the barbell velocity monitoring into the testing routine would permit the determination of the changes in strength across the entire spectrum of loads and offer a valid and practical proposal to evaluate the neuromuscular recovery status. The current article aimed to review in-depth the above-mentioned practical applications and some technological and technical aspects to consider when implementing the VBT in soccer.
Exploring the Relationship between Science, Religion & Attitudes toward Evolution Education
Authors: Kaloi Mahealani , Hopper Jonas D. , Hubble Gabriella , Niu Megan E. , Shumway Spencer G. , Tolman Ethan R. , Jensen Jamie L.
Published: February 2022

While some have argued that abandoning religious belief is the only way to help religious individuals accept evolution, we strongly contend that highlighting faith-evolution compatibility is much more effective. This article describes a professional development event for science teachers and religious educators highlighting ways to teach human evolution using a science inquiry approach coupled with methods for helping students reconcile science and religion. Since many science teachers in our population face a highly religious student body, are religious themselves, and have religious education integrated into the school system, we asked them to invite the religious educators (i.e., seminary teachers) at their schools to join them at the event. In addition, a group of religious educator faculty members from the local university joined the event. We collected data both before and after intervention. Results showed that the event strengthened understanding of the intersection between evolution and religion for this particular faith group, decreased feelings of conflict in participants themselves, and increased their confidence and comfort level in offering reconciliation to students and designing lesson plans that include human examples of evolution. Differential impacts on each group of participants are discussed in terms of what we can apply to efforts like this going forward.
The Effect of Subjective Fatigue on Auditory Processing in Musicians and Nonmusicians
Authors: Jain Saransh , Nataraja Nuggehalli Puttareviyah , Narne Vijaya Kumar
Published: February 2022

We assessed fatigue's effect on temporal resolution and speech perception in noise abilities in trained instrumental musicians. In a pretest-posttest quasiexperimental research design, trained instrumental musicians (n = 39) and theater artists as nonmusicians (n = 37) participated. Fatigue was measured using a visual analog scale (VAS) under eight fatigue categories. The temporal release of masking measured the temporal resolution, and auditory stream segregation assessed speech perception in noise. Entire testing was carried out at two time-points: before and after rehearsal. Each participant rehearsed for five to six hours: musicians playing musical instruments and theater artists conducted stage practice. The results revealed significantly lower VAS scores for both musicians and nonmusicians after rehearsal, indicating that both musicians and nonmusicians were fatigued after rehearsal. The musicians had higher scores for temporal release of masking and lower scores for auditory stream segregation abilities than nonmusicians in the pre-fatigue condition, indicating musicians’ edge in auditory processing abilities. However, no such differences in the scores of musicians and nonmusicians were observed in the post-fatigue testing. The results were inferred as the music training related advantage in temporal resolution, and speech perception in noise might have been reduced due to fatigue. In the end, we recommend that musicians consider fatigue a significant factor, as it might affect their performance in auditory processing tasks. Future researchers must also consider fatigue as a variable while measuring auditory processing in musicians. However, we restricted the auditory processing to temporal resolution and speech perception in noise only. Generalizing these results to other auditory processes requires further investigation.

Published: February 2022

Mayer–Rokitansky–Kuster–Hauser syndrome is characterized by congenital absence or hypoplasia of the uterus and upper two-thirds of the vagina in both phenotypically and karyotypically normal females with functional ovaries, whereas gonadal dysgenesis is a primary ovarian defect in otherwise normal 46,XX females. An association between these two conditions is extremely rare. We report a 21-year-old female presented with primary amenorrhea and undeveloped secondary sexual characteristics. The karyotype was 46,XX and the hormonal profile revealed hypothyroidism and hypogonadotropic hypogonadism. Pelvic MRI showed class I Mullerian duct anomaly with ovarian dysgenesis. Ultrasound showed bilateral thyroid hypoplasia and brain MRI suggested anterior pituitary hypoplasia. Levothyroxine and hormone replacement therapy were started.

Learning points

The simultaneous presentation of 46,XX gonadal dysgenesis, Mayer–Rokitansky–Kuster–Hauser syndrome, hypothyroidism, and pituitary hypoplasia is a Possibility.

Extensive evaluation should be made when a patient presents with one or more of these features.

The diagnosis imposes a significant psychological burden on patients and adequate counseling should be provided.

Hormone replacement therapy remains the only therapeutic option for the development of secondary sexual characteristics and the prevention of osteoporosis.

Published: February 2022

Analiza piśmiennictwa potwierdza skuteczność specjalistycznych opatrunków zawierających srebro i utrzymujących wilgotne środowisko w leczeniu ran. Opatrunki te zmniejszają obciążenie mikrobiologiczne rany, zapobiegają rozwojowi infekcji, wspomagają proces ziarninowania i naskórkowania. Brak rozwiniętej oporności drobnoustrojów na srebro stanowi obiecującą perspektywę miejscowego, antybakteryjnego leczenia ran i owrzodzeń. Skuteczność, dobra tolerancja oraz bezpieczeństwo związane z użyciem produktów z tej grupy znajdują potwierdzenie w badaniach in vitro i badaniach klinicznych. Opatrunek piankowy Mepilex® Ag, dzięki zawartości siarczanu srebra oraz miękkiej, silikonowej warstwy kontaktowej w technologii Safetac®, działa przeciwbakteryjnie, pozwala zmniejszyć ból podczas zmiany opatrunku oraz przyspiesza gojenie tkanek. Obecny w opatrunku węgiel aktywny zmniejsza nieprzyjemny zapach rany z cechami infekcji. Celem pracy była analiza badań w zakresie zastosowania opatrunku Mepilex® Ag w leczeniu ran.
Fosfomycyna w ciężkich zakażeniach wewnątrzbrzusznych u dzieci – doświadczenia własne na podstawie 4 opisów przypadku
Authors: Szmigielska Renata
Published: February 2022

Zakażenia wewnątrzbrzuszne u dzieci definiuje się jako procesy zapalne dotyczące jamy otrzewnej oraz położonych w niej narządów, będące odpowiedzią na obecność mikroorganizmów lub ich toksyn. Zalicza się je do grupy najcięższych bakteryjnych infekcji u dzieci, często o skomplikowanym przebiegu klinicznym. Narastająca antybiotykooporność patogenów oraz mała liczba nowych leków przeciwdrobnoustrojowych zmusza do poszukiwania nowych opcji terapeutycznych i połączeń lekowych w terapii skojarzonej. Fosfomycyna to jeden z najstarszych antybiotyków, w Polsce znana jest szczególnie w leczeniu zakażeń układu moczowego. W postaci dożylnej dostępna jest od niedawna, jednocześnie w tej postaci ma odmienne właściwości, co znacznie rozszerza wskazania do stosowania tego leku także w leczeniu ciężkich zakażeń w różnych grupach wiekowych. Bakteriobójcze działanie antybiotyku ujawnia się poprzez hamowanie syntezy ściany komórkowej bakterii o bardzo szerokim spektrum działania. Oddziałuje na bakterie Gram-ujemne i Gram-dodatnie, w tym szczepy szerokooporne na inne antybiotyki. W niniejszym artykule opisano 4 przypadki kliniczne zastosowania fosfomycyny u dzieci z powikłanymi zakażeniami wewnątrzbrzusznymi. U trojga pacjentów zaobserwowano poprawę stanu ogólnego i postęp w leczeniu zakażenia, u jednego z nich fosfomycyna nie była skuteczna. Opisani pacjenci w swoim skomplikowanym przebiegu wymagali leczenia wielokierunkowego i systemowego, ale pozytywny efekt fosfomycyny stosowanej w skojarzeniu z innym antybiotykiem w leczeniu zapalenia otrzewnej zachęca do szerszego uwzględnienia tego antybiotyku w schematach leczenia infekcji wewnątrzbrzusznych.

El presente estudio tuvo como objetivo determinar las diferencias en las funciones de la corteza prefrontal evaluadas a través de las tareas de Clasificación Semántica; Selección de Refranes y Metamemoria entre estudiantes con dos niveles de procedencia geográfica y sociocultural y observar si esos contrastes producían desiguales desempeños. Se realizó de una investigación descriptiva comparativa donde se utilizaron cuatro submuestras de niños de quinto y sexto grado de primaria. Dos de ellas de Ayacucho y dos de Lima. Las cuatro submuestras que fueron seleccionadas son de manera intencional, no probabilística (Sánchez y Reyes, 2006) en instituciones educativas estatales. Como instrumento se utilizó tres subtests de la Batería Neuropsicológica de Funciones Ejecutivas y Lóbulos Frontales de Flores, Ostrosky y Lozano (2012). Los resultados han permitido recomendar acciones preventivas y psicoeducativas para lograr mayores niveles de desempeño en las áreas afectadas por los contextos de pobreza y de falta de estimulación cognitiva y lingüística.

It is found that the 750 cm–1 band in pure tertiary butyl alcohol shows attributes of a complex structure that can be interpreted as a result of the superposition of several closely located lines belonging to different aggregates of alcoholmolecules. As the alcohol is diluted with neutral solvents, the width of this band passes through a maximum that corresponds to the concentration of the mixture with comparable contents of various most stable aggregates in the solution. The performed quantum-chemical calculations confirm the complexity of the 750-cm–1 band of pure alcohol caused by the aggregation of molecules by means of hydrogen bonds. The calculated energy gain due to the formation of a hydrogen bond (dimer) amounts to 19.7 kJ/mole, and the length of the hydrogen bridge equals 2.068 Å.
Can Nuclear Matter Consist of α-Particles?
Authors: Grinyuk B.E.
Published: February 2022

A sufficient condition for the spatial collapse in an infinite system of interacting Bose particles is obtained on the basis of the variational principle with the use of trial functions with the Jastrow pair correlation factors. The instability of a hypothetical infinite system of α-particles with respect to the spatial collapse is shown under the assumption of the Ali–Bodmer interaction potentials between such Bose particles. Thus, it becomes clear why the hypothetical nuclear matter is naturally treated with the use of at least the nucleon degrees of freedom.

Authors: Zinchenko A.E. , Serbin S.I. , Chernyak V.Y.
Published: February 2022

The paper presents the results of theoretical and experimental studies of the quenching process of nitrogen oxide synthesis products in a low-temperature air plasma. A developed experimental setup for researching the quenching consists of an air plasma generator with a power of up to 40 kW, as well as a coolant feeding system and control and measuring equipments. For the mathematical modeling of the processes, the numerical solution of the system of differential equations of conservation of mass, momentum, and energy in a turbulent system is used. Calculations and experiments were carried out in the range of variation of the quenching air flow rate 1–5 g/s at a plasma power of 31 kW, and a plasma air flow rate of 5 g/s. The calculated data on the values of heat fluxes are in satisfactory agreement with the experimental values. The theoretically and experimentally obtained value of the average cooling rate of the synthesis products 2.9 × 105 K/s significantly exceeds the cooling rate with traditional water cooling of elements.

У роботi продемонстровано можливiсть створення унiверсальних та ефективних SERS-пiдкладок шляхом контрольованої агрегацiї колоїдних наночастинок (НЧ) золота та срiбла на пiдкладках зi спецiально розробленою морфологiєю поверхнi. На вiдмiну вiд бiльшостi попереднiх робiт по розробцi та дослiдженню SERS-пiдкладок, в яких пiдсилення реалiзується переважно на оремих НЧ чи наноострiвцях, перехiд до багаторiвневого структурування пiдкладки та керованої агрегацiї осаджених на неї колоїдних плазмонних НЧ суттєво збiльшує ймовiрнiсть утворення “гарячих точок”, а також потрапляння в них молекул аналiту. Ефективнiсть запропонованого пiдходу продемонстрована на кiлькох органiчних аналiтах рiзного типу, зокрема, барвнику R6G, амiнокислотi цистеїн та антитiлах E. coli.
