Wirtualizacja działań społecznych i obywatelskich – szanse i zagrożenia – na przykładzie Kongresu osób z niepełnosprawnościami
Authors: Głąb Zbigniew
Published: January 2022

Ograniczenie bezpośrednich kontaktów, wynikające z pandemii COVID-19, sprawiło, że wiele przedsięwzięć – chcąc zachować swoją ciągłość – przeniosło się do internetu. Jednym z nich jest Kongres osób z niepełnosprawnościami – cykliczna inicjatywa społeczna angażująca i łącząca osoby oraz instytucje związane z tematyką niepełnosprawności – nastawiona na wprowadzanie zmian i nowych rozwiązań w tym obszarze. Celem badania było określenie, w jaki sposób Kongres zmienił swój charakter na skutek przeniesie-nia go do sieci, a także jakie są z tym związane nowe szanse, wyzwania i zagrożenia. W analizie przyjęto perspektywę ruchu społecznego z uwzględnieniem trudności w zastosowaniu tej teorii w odniesieniu do środowiska niepełnosprawnościowego. Na potrzebę analizy zostało przeprowadzonych 8 wywiadów swobodnych ukierunkowanych z organizatorami Kongresu i towarzyszących mu konwentów – będących ekspertami w dziedzinie niepełnosprawności, zaangażowanymi w organizację Kongresu osób z niepełnosprawnościami w 2020 r. Wyniki badań wskazują na odczuwalną zmianę charakteru kongresu – szczególnie związaną z aspektem społecznym, odnoszącym się do relacji i więzi pomiędzy uczestnikami. Wśród najważniejszych obaw znalazła się troska o utrzymanie rangi Kongresu jako wydarzenia wyróżniającego się i przy-ciągającego nowe osoby do kształtującego się zalążka reprezentacji osób z niepełnosprawnościami w Polsce. Do szczególnie podkreślanych zalet wirtualizacji należy natomiast zaliczyć wyrównywanie dostępności dla osób z różnymi niepełnosprawnościami
Kultura zdalna: szansa na uczestnictwo czy zagrożenie izolacją? Przypadek osób z niepełnosprawnością wzroku
Authors: Dubiel Monika
Published: January 2022

Zamknięcie polskich instytucji kultury dla publiczności w 2020 r. wymusiło przeniesienie ich działalności do internetu. Wpłynęło to istotnie na formę, jakość i częstotliwość kontaktu z kulturą całego społeczeństwa, jednakże najistotniejszą zmianą było to prawdopodobnie dla odbiorców z niepełnosprawnościami. W niniejszym tekście analizuję proces uzdalniania kultury pod kątem dostępności dla osób z niepełnosprawnością wzroku. Badam wynikające z niego możliwości i zagrożenia. Moim polem badawczym jest oferta kulturalna wybranych instytucji i organizacji pozarządowych. Materiał badawczy zbierałam, prowadząc wywiady ustrukturyzowane zarówno z przedstawicielami organizacji i instytucji, jak i z odbiorcami z niepełnosprawnością wzroku. Główne pytanie, na jakie staram się odpowiedzieć, brzmi: czy wirtualizacja kultury przyczynia się do zniesienia barier w dostępie do niej osób z niepełnosprawnością wzroku, czy wręcz przeciwnie, jedynie pogłębia już istniejące problemy? Ale są inne kwestie budzące moje zainteresowanie. Jaki wpływ wirtualizacja wydarzeń kulturalnych miała na ich częstotliwość oraz na stopień uczestnictwa odbiorców z niepełnosprawnością wzroku? Jakie innowacje wprowadziły instytucje kultury i organizacje w swojej dotychczasowej ofercie? Czy dostępność w przypadku kultury zdalnej jest łatwiejsza, czy trudniejsza, niż w przypadku kultury na żywo? Za ramę teoretyczną służą mi disability studies oraz accessibility studies.

Topically applied methyl nicotinate evokes a temporary inflammation on human skin
Authors: Monteiro Rodrigues Luis , Faloni de Andrade Sérgio , Rocha Clemente
Published: January 2022

Some challengers such as methylnicotinate (MN) have been used in human models to study the anti-inflammatory effect of topical formulations. However, MN skin responses are still poorly understood and widely varied. In the present study we aim to contribute to better characterise those responses. Eight healthy participants were selected. All procedures were approved by the institutional Ethics Committee. Two aqueous MN dilutions (0.5% and 1.0%) were left in contact for 1 minute in the anterior forearm skin. Following exposure, skin reactions were clinically and biometrically assessed at 30, 60 and 120 minutes and compared with baseline. Measurements involved the ICDRG clinical score scale and select analytical technologies - laser Doppler flowmetry, Polarised Spectroscopy, Transepidermal Water Loss Meter, and High Resolution Sonography. Results have shown that MN application evoked a maximal response at 30 minutes with an increase in the ICDRG score between 1-2. Significant changes in TEWL and microcirculation were observed, as was an increased dermal hypoecogenicity (edema), detected by HRS. These effects are compatible with a localised short-duration inflammation and reinforce the interest of MN to be used as a safe and controllable challenger in human models.

Authors: Torchi Gicelma da Fonseca Chacarosqui , Silva Denise , Antonio Maiza , Martins Daniel Valério
Published: January 2022

Este paper pretende discorrer sobre as línguas de fronteira no Mato Grosso do Sul. Esse trabalho nasce de algumas angústias sobre a maneira de como as línguas se relacionam dentro dos aspectos inerentes a educação, que deveria ser intercultural, fortalecendo a formação integral de crianças e jovens que residem nas regiões de fronteira. Sabemos que são as línguas que mobilizam, agregam e desagregam, e inclusive integram ou não a comunidade escolar de modo que a escola se perceba como um importante espaço intercultural. Sendo assim, este artigo objetiva, prioritariamente, discorrer sobre o que vem a ser interculturalidade, como percebemos os processos interculturais, como entendemos a interculturalidade, especificamente interculturalidade crítica rizomática e como o papel desse conceito empara espaços interculturais no ensino das línguas nas fronteiras do Brasil, especificamente na fronteira sul de Mato Grosso do Sul/ Brasil.

Published: January 2022

Chickpea (Cicer arietinum L.) production is constantly compromised by a complex of pathogens which cause wilt and root rot (WRR). Therefore, biological control and organic products have regained great importance in the last few years. In this work, polyphenols were obtained from ethanolic extracts through the ultrasound-microwave assisted technique from the plant species chinese privet leaves (Ligustrum lucidum) and moringa leaves (Moringa oleifera). A qualitative analysis through reverse phase high-performance liquid chromatography electrospray ionization mass spectrometry (RP-HPLC-ESI-MS) was conducted, so that their biological effectiveness under greenhouse conditions was determined by each group of polyphenols against Fusarium oxysporum f. sp. ciceris, Fusarium solani, and Macrophomina phaseolina which comprise the wilt and root rot complex. A complete randomized block design was established with three blocks and five treatments with nine replications each. Treatments were: Polyphenols of Ligustrum lucidum, polyphenols of Moringa oleifera, the fungicide Benomyl, the inoculated check, and the untreated check. The analysis of variance was performed and mean comparison with Duncan`s multiple range test (0.05). The results indicate that all groups of polyphenol had in their chemical composition, some compounds of known microbial activity, such as hydroxycinnamic acid, flavones, anthocyanins, catechins, and alkyphenols. Under greenhouse conditions, plants that had the lowest incidence and severity of the disease, were those treated with polyphenols from L. lucidum with 66% incidence, and were statistically different to the rest of the treatments.
KOLESTEATOM VARLIĞININ ÖNGÖRÜLEBİLMESİNDE KANDAKİ NÖTROFİL/LENFOSİT ORANININ ÖNEMİ
Authors: ÇANAKCI Hasan , TULACI Kamil Gokce
Published: January 2022

AMAÇ: Son yıllarda nötrofil/lenfosit oranı (NLO), platelet/lenfosit oranı (PLO) ve lenfosit/monosit oranı (LMO) oranları inflamasyonun bir göstergesi olarak çeşitli hastalıkların tanı ve takibinde kullanılmaktadır. Çalışmamızda da kronik otit hastalarında, inflamasyonla yakından ilişkili olduğu gösterilmiş olan kolesteatomun NLO, PLO ve LMO ile ilişkisinin incelenmesi amaçlanmıştır.

GEREÇ ve YÖNTEM: Kliniğimizde 2013-2019 yılları arasında kronik otit nedeniyle ameliyat edilen 138 hastanın dosyaları retrospektif olarak incelendi. Hastalar grup 1: kolesteatomlu kronik otit, grup 2: kolesteatomsuz kronik otit olarak sınıflandırıldı. Tüm hastaların yaş, cinsiyet, NLO, PLO, LMO verileri incelenerek kaydedildi ve gruplar arasında karşılaştırıldı.

BULGULAR: Grup 1’de 61 grup 2’de 77 hasta vardı. Gruplar arasında yaş ortalamaları açısından fark yoktu. Grup 1’de bayan hasta oranı grup 2 ye oranla daha düşüktü (p=0,042). Gruplar arasında kan hücrelerinin birbirine oranları incelendiğinde NLO, grup 1'de grup 2'ye göre anlamlı düzeyde yüksek izlenirken (p=0,006), PLO ve LMO da gruplar arasında istatistiksel açıdan anlamlı fark izlenmedi (sırasıyla p=0,913, p=0,111). NLO ≥1,734 kesme (cut-off) değeri, kolesteatom varlığını göstermede %75,4 duyarlılık ve %46,8 özgüllükte anlamlı olarak izlendi.

SONUÇ: Çalışmamızda farklı hastalıkların tanı ve takiplerinde inflamasyon göstergesi olarak anlamlı bilgiler verdiği gösterilen NLO’nın kolesteatom varlığını tahmin etmede de anlamlı olduğu görülmüştür. Kronik otit ve eşlik eden retraksiyon, adezyon veya sık enfeksiyon şikâyeti olan ve timpanoplasti sonrası nüks veya rezidü kolesteatom açısından risk taşıyan bireylerin takiplerinde NLO’nın değerlendirilmesinin hastaların takipleri açısından faydalı olabileceğini düşünmekteyiz.
Hepatit-B ve C enfeksiyonlarının böbrek transplatasyonunda graft ve karaciğer fonksiyonlarına etkisi: Türkiye'den tek merkez deneyimi
Authors: KARAER BÜBERCİ Refika , PAYDAS Saime
Published: January 2022

AMAÇ: İmmünsüpresif tedaviden dolayı hepatit-B veya C enfeksiyonlarının böbrek nakilli hastalarda graft ve hasta sağ kalımına olumsuz etki ettiği konusu tartışmalıdır. Çalışmamızın amacı böbrek nakilli hastalarda hepatit-B ve C enfeksiyonlarının hasta ve graft üzerine etkilerini değerlendirmektir.

GEREÇ VE YÖNTEMLER: Çalışmaya 66 böbrek nakil hastası alındı. Anti-HCVpozitif beş hasta ve Hbs-Ag pozitif dokuz hasta viral hepatit grubunu oluşturdu. Geri kalan 52 hasta (anti-HCV, Hbs-Ag negatif) viral hepatiti olmayan grubu oluşturdu. Hastane kayıtları retrospektif olarak tarandı. Nakil sonrası ilk üç yıllık AST, ALT, albumin, hesaplanmış glomerüler filtrasyon hızı (hGFH) not edildi.

BULGULAR: Transplant sonrası takip süresi ortalama olarak viral hepatit grubunda 62,4 ±48,2 ay viral hepatiti olmayan grupta 35,3±15,7 ay idi. Cinsiyet, donör tipi, yaş, transplant sonrası nakil süresi açısından iki grup arasında anlamlı fark yoktu. Sadece nakil öncesi diyaliz süresi hepatit grubunda anlamlı daha uzundu. hGFH (sırasıyla viral hepatit olmayan grupta 73,5±22,7, 69,3±23, 63,5±22,1 mL/dk, viral hepatit grubunda 78,8±15,7, 70,6±12,5, 61,2±13,1 mL/dk), AST, ALT, albumin birinci, ikinci, üçüncü yıllarda iki grupta benzerdi Ancak üçüncü yılın sonundaki hGFH'deki düşüş hızı ve AST/ALT’deki artış hızı viral hepatit grubunda istatistiksel olarak anlamlı daha fazlaydı. hGFH'deki düşüşün kadınlarda daha hızlı olduğu tespit edilirken, kolerasyon analizinde yaş ve nakil öncesi diyaliz süresinin hGFH'deki düşüşe etkisi bulunmadı.

SONUÇ: Üç yıllık takipte hGFH ve AST/ALT değerleri iki grupta benzerdi. Hiçbir hastada graft kaybı, karaciğer yetmezliği, ölüm gelişmedi. Günümüzde hepatit-C enfeksiyonu için başarılı tedaviler uygulanmakla birlikte anti viral tedavi uygulanmamış hepatiti pozitif olan son dönem böbrek yetmezlikli hastalarda böbrek nakli, iyi bir değerlendirme sonrası güvenli ve etkili bir tedavi seçeneği olarak kabul edilebilir.
PEDİYATRİK SEREBRAL VENÖZ TROMBUS VAKALARINDA KONTRASTSIZ BT: HU DEĞERLERİ TANISAL GÜCÜ ARTTIRABİLİR Mİ?
Authors: AYDIN Sonay , FATİHOĞLU Erdem , GÖKHARMAN Fatma
Published: January 2022

Giriş: Serebral venöz sinüs trombozu (SVST) morbidite ve mortalitesi yüksek, çocukluk çağında görece daha nadir izlenen bir patolojidir. Görüntüleme yöntemlerindeki son gelişmeler ile SVST’nin tanı sıklığı artmış ve bu hastalık ile perinatal dönemdeki beyin hasarı arasındaki ilişkiler daha görünür hale gelmiştir. SVST nonspesifik nörolojik bulgular ile ortaya çıktığından tanı alma süresi uzayabilmektedir. Bu çalışmada tromboze serebral sinüslerden Hounsfield unit (HU) ölçümleri yapılarak SVST tanısında eşik HU değerleri tespit edilmesi ve HU değerlerinin hematokrit düzeyleri ile potansiyel ilişkisinin tespit edilmesi amaçlanmaktadır.

Gereç ve yöntem: Manyetik rezonans venografi (MRV) incelemesi, kontrastsız beyin BT incelemesi ve hematokrit değerleri olan çocuk hastalar çalışmaya dahil edilmiştir. 16 adet tromboze serebral venden HU değeri ölçülmüştür. 30 pediatrik hasta ile kontrol grubu oluşturulmuştur. Kontrol grubunda serebral sinüslerin orta kesiminde HU ölçümü gerçekleştirilip sadece bir sinüsün ortalama değeri veri olarak kaydedilmiştir. Kontrol grubunda hematokrit değerleri ile HU ölçümleri arasındaki ilişkiyi belirlemek ve bu ilişkinin yaş gruplarına göre değişimini incelemek amacıyla, katılımcılar üç yaş grubuna ayrılmıştır.

Bulgular: SVST’den ölçülen HU değeri kontrol grubu HU değerine kıyasla anlamlı olarak yüksek izlenmiştir (61’e karşı 48,6, p < 0.01). Kontrol grubu 0-1 yaşa ait ortalama sinüs HU değeri, tüm kontrol grubuna ait ortalama HU değerine göre anlamlı olarak düşüktür (44’e karşı 48,6, p < 0.05). Serebral venöz sinüslerdeki HU değerinin 60 ve üzeri bulunmasının %98 duyarlılık ve %80 özgüllük ile tromboz varlığını öngörebildiği bulunmuştur (AUC = 0.912).

Sonuç: Dural sinüslerden, kontrastsız beyin BT kullanılarak ölçülen yüksek HU değerleri SVST tanısında yüksek özgüllüğe sahiptir.

Argulus is an ectoparasite that frequently infects goldfish, with severe effects and a high death rate. The use of plant extracts has been widely reported to have antiparasitic activities, including one of the solasodine compounds in sour eggplant extracts. This research evaluated the antiparasitic activities of Compositions A (Solanum ferox and Zingiber zerumbet extract at 400 and 200 ppm, respectively), B (SFE and Boesenbergia pandurata at 900 ppm), and C (single Solanum ferox at 400 ppm). The research stages comprised 1) isolation and analysis of solasodine content in sour eggplant extracts and its extract composition, 2) in vitro antiparasitic activities on Argulus sp. at doses of 50 and 100 ppm with a testing time of 60–240 minutes, and 3) in vivo antiparasitic activities on Argulus sp. on goldfish at a dose of 100 ppm and observation for 2–12 hours of medication. The results showed that sour eggplant extracts had a solasodine concentration of 7.151 mg/L, whereas the derivative compositions A, B, and C were 656, 485, and 295 ppm, respectively. The in vitro testing demonstrated that composition A was effective for killing approximately 80–100% of Argulus, whereas compositions B and C killed 80–90% and 60–70%, respectively. Viewed from the effectiveness for killing parasites, the result was excellent (above 50%). The in vivo medication test was continued using three extract compositions at a dose of 100 ppm. Compositions A, B, and C were found to be capable of releasing 81.33, 75.67, and 71.00 arguli, respectively, per fish. We concluded that the single SFE extract and a concoction with BPE and ZZE had reasonable antiparasitic activity, whereas the concoction of SFE and ZZE killed more Argulus parasites at a higher rate.
Superconductivity in Carbonaceous Sulfur Hydride: Further Analysis of Relation between Published AC Magnetic Susceptibility Data and Measured Raw Data
Authors: Hirsch Jorge
Published: January 2022

In arXiv:2111.15017v1 [1], Dias and Salamat posted some of the measured data for ac magnetic susceptibility of carbonaceous sulfur hydride, a material that was reported in Nature 586, 373 (2020) [2] to be a room temperature superconductor. They provided additional measured data in arXiv:2111.15017v2 [3]. Here I provide an analysis of these data. The results of this analysis indicate that the claim of ref. [2] that magnetic susceptibility measurements support the conclusion that the material is a room temperature superconductor is not supported by valid underlying data.
The influence of intellectual capital and innovations on the economic development of the world and national economy

We consider in the study that the existing economic model will inevitably be replaced by a new effective model of creative and competitive economic development. Technological innovations have caused the rapid growth of the world economy. As the result, production costs have been reduced and the profits of corporations in many sectors of the world economy have increased. Innovation is a factor of rise in Kondratiev cycles. Innovations give an impetus to increase the value added of a country’s economy. The article asserts that intellectual capital is the basis and is becoming an increasingly important component of national and world development. The article has investigated in which way innovation activities affect real GDP and has suggested the answer to the question on what stage of the Kondratiev cycles the world economy is. Innovation as an object of intellectual capital is introduced in the form of patents and other intellectual property. We have analyzed the relevant trends for 2004-2020. The research has determined that by 2030, a significant increase in the number of patent applications is expected. The article has examined the dependence of the world real GDP on the number of filed patent applications in the world by constructing trend lines. It has been found that the largest approximation with a coefficient of determination greater than 0.92 is a polynomial trend line, in which the dynamic growth with a small number of patent applications is inhibited by a sharp increase in their number. The research has defined that the phases of the cyber revolution correlate with Kondratiev waves. The modern phase is characterized by the rapid generation and dissemination of innovations. The article has examined the filing of patent applications in the top 20 countries around the world, among which the leading positions are occupied by China, the USA, and Japan. By constructing trend lines, the research has analyzed the dependence of Ukraine’s real GDP on the number of innovations and has shown that there is no such clear dependence. This indicates the raw material orientation of the Ukrainian economy. The article states that it is extremely important for Ukraine to make the transition from the triad model (with state-monopoly capitalism) to the national economic model, which corresponds to the approaches of the people’s capitalism.

As a result of the 2008 financial crisis, the international financial system underwent a fundamental change. The crisis has highlighted various weaknesses in the economic system. One of these weaknesses was the unregulated nature of investment markets and their inefficient structural structure. Funds managed by investment fund managers have also been hit hard by the crisis. In the post-crisis period of 2008, there was a dynamic economic boom, which also affected the types of investment funds and their changes. However, the economic crisis caused by the COVID-19 pandemic from 2020 onwards is a special crisis. Its unique nature is reflected in the fact that financial markets have remained stable under the influence of central banks. This, in turn, did not necessarily affect the investment market, and in particular investment funds, as expected in the event of a downturn. In our research, we illustrate the change of investment funds along economic cycles through the quantitative changes of Hungarian investment funds. In our analysis, we illustrate the evolution of fund changes through hierarchical cluster analyzes. In the course of our research, we found that Hungarian investment funds move in line with market and retail investment trends, and the structure of investment funds does not show a significant change during the sixteen years examined, regardless of changes in economic cycles.

According to touristic cycle-theory, raising and decreasing waves show cyclicality showing more and more oscillation in time and depth. It has impact on intermediary sector as well as on relationship between tourism and transportation. It can be observed that air transportation transformed after recession but got out of trouble strengthened. Current transformation can be described as responsible fly, next crisis can be avoided only by evolving a comprehensive, sustainable development. Under green transformation we understand the decreasing of emission of pollutant gases by aviation, reducing the power consumption and participation in environment protecting projects. In terms of future it means a serious problem that according to research of Eurocontrol carbon emission can be doubled, the international organizations called aviations for reducing their emission already in 2018. In our research we looked for answers to the questions of why the sustainability of airlines has come into view just now and what people think about it as well as what the influence of the current situation will be on tourism and its transformation. A combination of economic, social, environmental, and psychological factors has recently been affecting the development of sustainable air traffic. Changes have arisen due to economic challenges as airlines faced restrictions which they have never seen in the past, such as border closures and several week long quarantine requirements for passengers. These resulted in the grounding the aircraft of airlines within a few weeks. Due to the pandemic, all airlines were in need of financial support from the Member States of the European Union. Each Member State and their cities with airports have an interest in the reduction of pollutant gases (the total CO2 emission of air traffic is 859 million tonnes per year, IATA 2020). Due to interdependence resulting from the crisis, a responsible air development programme has been started. Psychological factors have come to the forefront due to the pandemic, which means further challenges for the airlines. How could overcrowded flights be made safer for passengers? How would it be possible to win back the confidence of passengers? As for the tourism industry, the resumption of flights and the operation of the sector are crucial issues (58% of international passengers fly to their destination) and a lot depends on the recoverability of psychological sustainability. Our travel habits should change in the future and this process would show the path to more balanced development.

In this article, the availability and reliability of a remote video monitoring system for offshore sea farming plants are studied and tested in laboratory. The scope of the system is to ensure a video surveillance infrastructure so to supervise breeding cages along with the fish inside them, in order to contrast undesired phenomena like fish poaching as well as cages damages. The system is installed on a cage floating structure: it is mainly composed of an IP camera that is controlled by a Raspberry Pi Zero which is the core of the system. Images are streamed thanks to a 3G/4G dongle, while the overall system is powered via two photovoltaic panels charging a backup battery. Simulations are carried out considering two seasonal functioning periods (i.e., winter and summer): each of them is characterised by temperature trends defined according to the average temperatures of the system deployment site, 8 km offshore the city of Piombino, Italy. In order to optimise power consumption without hindering application scenario requirements, the system operates according to a duty cycle of 2 minutes out of 15 (i.e., 8 minutes of operation per hour). The performances of the system are then tested in laboratory exploiting a climatic chamber so to simulate different environmental conditions: variations on image quality are then analysed in order to identify possible dependencies on critical situations related to specific temperature and relative humidity values and to the presence of salt in the air.
From electronic navigational chart data to sea-bottom models: Kriging approaches for the Bay of Pozzuoli

Published: January 2022

Electronic Navigational Charts (ENCs), official databases created by a national hydrographic office and included in Electronic Chart Display and Information System (ECDIS), supply, among essential indications for safe navigation, data about sea-bottom morphology in terms of depth points and isolines. Those data are very useful to build bathymetric 3D models: applying interpolation methods, it is possible to produce a continuous representation of the seafloor for supporting studies concerning different aspects of a marine area, such as directions and intensity of currents, sensitivity of habitats and species, etc. Many interpolation methods are available in literature for bathymetric data modelling: among them kriging ones are extremely performing, but require deep analysis to define input parameters, i.e. semi-variogram models. This paper aims to analyze kriging approaches for depth data concerning the Bay of Pozzuoli. The attention is focused on the role of semi-variogram models for Ordinary and Universal kriging. Depth data included in two ENCs, namely IT400129 and IT400130, are processed using Geostatistical Analyst, an extension of ArcGIS 10.3.1 (ESRI). The results testify the relevance of the choice of the mathematical functions of the semi-variogram: Stable Model supplies, for this case study, the best performance in terms of depth accuracy for both Ordinary and Universal kriging.
Simulation study of the photovoltaic panel under different operation conditions

Published: January 2022

An increase in the temperature of the photovoltaic (PV) cells is a significant issue in most PV panels application. About 15–20% of solar radiation is converted to electricity by PV panels, and the rest converts to heat that affects their efficiency. This paper studies the effects of temperature distribution on the PV panel at different solar radiation values, temperatures under different operation conditions in January and July. A 3D model of the PV panel was simulated with ANSYS software, depending on the various values of temperatures and solar radiation values obtained using mathematic equations. The simulation results indicate that PV panel temperature lowered with solar radiation values lower in January, and the temperature was homogeneous on the PV panel surface. An increase in the solar radiation value and temperature in July led causes heating of the PV panel with observed a convergence of the maximum and average temperature of the panel. Thus, the PV panel temperature increase is directly proportional to the solar radiation increase that causes lower performance. Cooling the PV panel by passive or active cooling represents the optimum option to enhance their performance and avoid increasing the PV cells' temperature at temperature increase.

Published: January 2022

Characterising the aeroacoustic noise sources generated by a rotating wind turbine blade provides useful information for tackling noise reduction of this mechanical system. In this context, microphone array measurements and acoustic source mapping techniques are powerful tools for the identification of aeroacoustic noise sources. This paper discusses a series of acoustic mapping strategies that can be exploited in this kind of applications. A single-blade rotor was tested in a semi-anechoic chamber using a circular microphone array.
The Virtual Rotating Array (VRA) approach, which transforms the signals acquired by the physical static array into signals of virtual microphones synchronously rotating with the blade, hence ensuring noise-source stationarity, was used to enable the use of frequency domain acoustic mapping techniques. A comparison among three different acoustic mapping methods is presented: Conventional Beamforming, CLEAN-SC and Covariance Matrix Fitting based on Iterative Re-weighted Least Squares and Bayesian approach. The latter demonstrated to provide the best results for the application and made it possible a detailed characterization of the noise sources generated by the rotating blade at different operating conditions.

New low-cost measuring devices require that the box housing and electronics have the cost aligned with the sensing system. Nowadays, metallic clips and/or glue are commonly used to fix the electronics to the box, thus providing the same motion of the structure to the sensing element. However, these systems may undergo daily or seasonal thermal cycles, and the combined effect of thermal and mechanical stress can determine significant uncertainties in the measurand evaluation. To study these effects, we prepared some parallel plates capacitors by using glue as a dielectric material. We used different types of fixing and sample assembly to separate the effects of glue softening on the capacitor active area and plates distance. Therefore, we assessed the sample modification by measuring the capacitance variation during controlled temperature cycles. We explored possible non-linear behaviour of the capacitance vs. temperature, and possible effects of thermal cycles on the glue geometry. Further work is still needed to properly assess the nature of this phenomenon and to study the effect of mechanical stress on the sample’s capacitance.

Multidomain comfort theories have been demonstrated to interpret human thermal comfort in buildings by employing human-centered physiological measurements coupled with environmental sensing techniques. Thermal comfort has been correlated with brain activity through electroencephalographic (EEG) measurements. However, the application of low-cost wearable EEG sensors for measuring thermal comfort has not been thoroughly investigated. Wearable EEG devices provide several advantages in terms of reduced intrusiveness and application in real-life contexts. However, they are prone to measurement uncertainties. This study presents results from the application of an EEG wearable device to investigate changes in the EEG frequency domain at different indoor temperatures. Twenty-three participants were enrolled, and the EEG signals were recorded at three ambient temperatures: cold (16 °C), neutral (24 °C), and warm (31 °C). Then, the analysis of brain Power Spectral Densities (PSDs) was performed, to investigate features correlated with thermal sensations. Statistically significant differences of several EEG features, measured on both frontal and temporal electrodes, were found between the three thermal conditions. Results bring to the conclusion that wearable sensors could be used for EEG acquisition applied to thermal comfort measurement, but only after a dedicated signal processing to remove the uncertainty due to artifacts.

Published: January 2022

Preserving culture is an important aspect of the life of indigenous peoples because it is identical to a lifestyle that is still guided by local customs. The process of cultural preservation in indigenous peoples cannot be separated from the important role of the community as an academic locus and Du'a Mo'an Watu Pitu as the responsible one. Based on this reality, this study aims to determine the leadership model of a democratic school principal based on local wisdom and examine the role of du'a moan watu pitu in maintaining the Kula babong culture (democracy) in the Sikka Krowe community. The research method used in this research is descriptive qualitative with an ethnographic approach. The subjects in this study were 4 principals of private and public schools, four Sikka krowe traditional leaders who inhabit each region, and culturalists in the Krowe Ethnic community, Sikka krowe Regency, East Nusa Tenggara. Data collection techniques used are observation, interviews and documentation. The results showed that the school principal's leadership model was based on the values of Sikka Krowe's local wisdom: the value of honesty, the value of courage, the value of kula babong, and charisma. Du'a Mo'an Watu Pitu's role in preserving the Kula Babong culture (democracy) is to maintain the integrity of traditional institutions, perform traditional rituals, resolve social conflicts and uphold justice.
