Abstract:
AbstractThe aim of this paper is to provide information about the neurophysiologic model of tinnitus and Tinnitus Retraining Therapy (TRT). With this overview of the model and therapy, professionals may discern with this basic foundation of knowledge whether they wish to pursue learning and subsequently implement TRT in their practice. This paper provides an overview only and is insufficient for the implementation of TRT.

Abstract:
Tinnitus refers to the perception of ringing sounds in the ear that are not heard by others. Counseling plays a vital role in tinnitus intervention. Counseling provides correct information about tinnitus and hearing loss, corrects any misunderstandings related to tinnitus, and suggests precise alternative interventions for tinnitus. In this review, we aimed to examine the counseling contents in Tinnitus Retraining Therapy (TRT), Cognitive Behavioral Therapy (CBT), and Tinnitus Activities Treatment (TAT) to identify information that could be useful for counseling approaches and contents for the various tinnitus intervention methods. We searched Web of Science, Embase, Science Direct, and PubMed for relevant articles. Of the 5,283 articles, 31 were included in the final review of counseling contents for TRT, CBT, and TAT. Based on our findings, we were able to summarize the main contents of counseling in TRT, CBT, and TAT. Although the contents of counseling may vary depending on the individuals with tinnitus, our review provided information that may help audiologists or hearing professionals further understand the fundamentals of counseling for each tinnitus intervention. Our review may serve as a guideline for tinnitus counseling according to tinnitus interventions.

Abstract:
Purpose.To assess the reliability and comparability of measuring central corneal thickness (CCT) and thinnest corneal thickness (TCT) using a new Scheimpflug-Placido analyzer (TMS-5, Japan) and ultrasound (US) pachymetry.Methods.Seventy-six healthy subjects were prospectively measured 3 times by 1 operator using the TMS-5, 3 additional consecutive scans were performed by a second operator, and ultrasound (US) pachymetry measurements were taken. The test-retest repeatability (TRT), coefficient of variation (CoV), and intraclass correlation coefficient (ICC) were calculated to evaluate intraoperator repeatability and interoperator reproducibility. Agreement among the devices was assessed using Bland-Altman plots and 95% limits of agreement (LoA).Results.The intraoperators TRT and CoV were <19 μm and 2.0%, respectively. The interoperators TRT and CoV were <12 μm and 1.0%, respectively, and ICC was >0.90. The mean CCT and TCT measurements using the TMS-5 were 15.97 μm (95% LoA from −26.42 to −5.52 μm) and 20.32 μm (95% LoA from −30.67 to −9.97 μm) smaller, respectively, than those using US pachymetry.Conclusions.The TMS-5 shows good repeatability and reproducibility for measuring CCT and TCT in normal subjects but only moderate agreement with US pachymetry results. Caution is warranted before using these techniques interchangeably.

Abstract:
A study was conducted with 204 Merino ewes as experimental units to assess the effectiveness of four estrus synchronization protocols. The ewes were divided into four groups: TRT A (Control), TRT B (Intravaginal sponges for 14 days), TRT C (Double prostaglandin injections on days 0 and 11) and TRT D (Intravaginal sponges for 14 days, a single prostaglandin injection on day 12, plus PMSG). Six rams were used to detect heat, with standing to be mounted as the primary indicator of estrus. There were no significant differences (p>0.05) in estrus response rates among the groups: 94.10% for TRT B, 96.20% for TRT D, and 90.20% for both TRT A and TRT C. Additionally, the time from treatment withdrawal to the onset and end of estrus showed no significant variation (p>0.05). The duration of estrus differed significantly among the treatments (TRT D, TRT A, and TRT C) with notable differences at specific time intervals: 48h and 36h for TRT D, and 24h for TRT C (p<0.05). Significant differences were also found between TRT B and TRT D at 48h and 60h post-treatment withdrawal. Additionally, TRT D showed high significance at 24h and 36h intervals. At 72 hours, both TRT C and TRT D were significant, with TRT D remaining significant at 84h (p<0.05). Overall, combination treatment (TRT D) was more effective in synchronizing estrus in Merino ewes, resulting in a higher response rate and shorter interval from treatment withdrawal to estrus onset.

Abstract:
Background Tinnitus retraining therapy (TRT) is a standard treatment for tinnitus that consists of directive counseling and sound therapy. However, it is based on face-to-face education and a time-consuming protocol. Smart device–based TRT (smart-TRT) seems to have many advantages, but the efficacy of this new treatment has been questioned. Objective The aim of this study was to compare the efficacy between smart-TRT and conventional TRT (conv-TRT). Methods We recruited 84 patients with tinnitus. Results were compared between 42 patients who received smart-TRT and 42 control participants who received conv-TRT. An interactive smart pad application was used for directive counseling in the smart-TRT group. The smart pad application included detailed education on ear anatomy, the neurophysiological model of tinnitus, concept of habituation, and sound therapy. The smart-TRT was bidirectional: There were 17 multiple choice questions between each lesson as an interim check. The conv-TRT group underwent traditional person-to-person counseling. The primary outcome measure was the Tinnitus Handicap Inventory (THI), and the secondary outcome measure was assessed using a visual analogue scale (VAS). Results Both treatments had a significant treatment effect, which comparably improved during the first 2 months. The best improvements in THI were –23.3 (95% CI –33.1 to –13.4) points at 3 months and –16.8 (95% CI –30.8 to –2.8) points at 2 months in the smart-TRT group and conv-TRT group, respectively. The improvements on the VAS were also comparable: smart-TRT group: –1.2 to –3.3; conv-TRT: –0.7 to –1.7. Conclusions TRT based on smart devices can be an effective alternative for tinnitus patients. Considering the amount of time needed for person-to-person counseling, smart-TRT can be a cost-effective solution with similar treatment outcomes as conv-TRT.

Abstract:
There is no conclusive evidence as to whether patients with testosterone deficiency (TD) who benefit from testosterone treatment (TRT) must continue the treatment for the rest of their lives. In some patients, the effect of TRT does not maintained after stopping TRT and, some patients show no significant TD symptoms, with normal testosterone levels after TRT cessation. Therefore, we investigated the predictive factors of response maintenance after TRT cessation. A total of 151 men with TD who responded to TRT were followed up for six months after TRT discontinuation. Ninety-two patients (Group I) failed to show response maintenance; 59 patients (Group II) had a maintained response. The groups did not differ in baseline characteristics or the type of TRT (oral, gel, short/long-acting injectables). However, TRT duration was significantly longer (10.7 vs. 5.2 months), and peak total testosterone (TT) level was significantly higher (713.7 vs. 546.1 ng/dL), in Group II than in Group I. More patients regularly exercised in Group II than in Group I (45.8% vs. 9.8%, p < 0.001). A multivariate logistic regression analysis revealed that exercise (B = 2.325, odds ratio = 10.231, p < 0.001) and TRT duration (B = 0.153, Exp(B) = 1.166, p < 0.001) were independent predictive factors of response maintenance. In men with TD who respond to TRT, longer treatment periods can improve the response durability after TRT cessation, regardless of the type of TRT. Additionally, regular exercise can increase the probability of maintaining the response after TRT cessation.

Abstract:
e20093 Background: Thoracic radiotherapy (TRT) for extensive stage small-cell lung cancer (ES-SCLC) patients is controversial. Slotman et al. (2015) demonstrated a 2-year overall survival (OS) benefit for patients who received TRT after chemotherapy (CT) and prophylactic cranial irradiation (PCI), but obtaining a median OS of 8 months (m). We wanted to confirm results of Slotman’s work in a real-world setting with higher doses of TRT. Methods: We retrospectively reviewed 67 patients with ES-SCLC treated between 1995 and 2015, after completing CT administration. Patients with initial brain metastasis and those who rejected PCI were excluded. All of them received PCI. All patients were followed until death. Disease-specific survival (DSS), disease-free survival (DFS) and OS were analyzed and computed with Kaplan-Meier method, groups were compared with log-rank test. Adjusted hazard risk (HR) of death for TRT was estimated through multivariate Cox model. Results: Patients (59 male, 8 female) with median age 64 years (42-79) had a median Karnofsky performance status (KPS) of 80. Twenty-three patients received high doses TRT (mean dose: 45.4 Gy). No significant differences between groups were found in age, gender, KPS, number of metastatic sites, residual thoracic disease or smoke activity. Non-TRT patients had more metastatic lesions. Median OS for TRT-patients was 19.9 m and 11.2 m for non-TRT patients (p = 0.01). DSS was 23.4 m for TRT-patients and 13.5 m for non-TRT patients (p = 0.007). For TRT-patients and non-TRT patients, median DFS were 15.5 and 8.3 m (p = 0.001), respectively. In the multivariate analysis, TRT (p = 0.003, HR 0.35), KPS (p = 0.012, HR 0.95) and residual thoracic disease (p = 0.02, HR 3.30) were independent prognostic factors for survival. The best benefit was obtained for those patients with consolidative TRT (CTRT): OS of 24.7, DSS of 27.4 and DFS of 15.9 m, compared with 13.4 (p = 0.003), 13.9 (p = 0.003) and 8.5 m (p = 0.007), respectively, for patients not treated with CTRT. Conclusions: TRT impacts positively in OS, DSS and PFS and should be administered to ES-SCLC patients who complete CT and PCI. High TRT doses could achieve better results than those described for low TRT doses.

Abstract:
Background and Objectives Tinnitus retraining therapy (TRT) is a well-known effective method for tinnitus management by retraining the brain to achieve habituation of tinnitus. The mobile device based TRT can let both clinicians and patients be free from time and space limitations and secure cost-effectiveness. The study aimed to investigate whether the mobile-based TRT is inferior or not to the conventional TRT in treatment outcomes for chronic subjective tinnitus.Subjects and Method A prospective randomized controlled trial was conducted in a single tertiary hospital. Adult patients with chronic subjective tinnitus were enrolled. Pure tone audiometry, State-Trait Anxiety Inventory [(STAI), axis1 and axis2], Beck Depression Inventory, Pittsburgh Sleep Quality Index, and a survey for TRT were evaluated. Tinnitus Handicap Inventory (THI), Visual Analog Scale (VAS) of tinnitus, and Tnnitogram were compared at the start, then at one month and three months of the treatment. The mobile group was subdivided into the treatment effective group and the refractory group. Demographics, baseline tinnitus severity, and therapy compliance were comparatively analyzed.Results A total of 19 patients for the mobile-based TRT and 21 patients for the conventional TRT were enrolled. THI scores and Tinnitus scores using VAS were significantly reduced in the mobile group after the treatment. Furthermore, THI and STAI were significantly more improved in the conventional group than in the mobile-based TRT at one and three months of the treatment. Also, the effective group of the mobile device based TRT was statistically younger than the refractory group and had a higher understanding of the treatment method.Conclusion The mobile-based TRT could improve THI and VAS scores of tinnitus at one and three months of treatment. However, the conventional TRT showed better outcome than the Mobile-based TRT with respect to THI scores. The mobile-based TRT can be one of different potential options that clinicians can apply to tinnitus patients who cannot follow the conventional TRT or limited candidate. Further improvement of the mobile device based TRT would be needed.

Abstract:
Excessive electroconductivity measurements have been observed in the surface layer of subirrigated substrates. A hydrophilic gel and rockwool were used as pot mulches in order to reduce the surface layer salt buildup by absorbing the salts and/or reducing evaporation. Six treatments of `Crimson Fire' and `Victoria' CVI geraniums were grown in 11 cm. pots. Treatments were: Trt 1 - top irrigation, N source 20-10-20; trt 2 - subirrigation, N source 20-10-20; trt 3 - subirrigation, N source in equal portions of 20-10-20 and CRF, gel mulch; trt 4 - subirrigation, N source CRF, gel mulch; trt 5 - subirrigation, N source in equal portions of 20-10-20 and CRF, wool mulch; trt 6 - subirrigation, all N source CRF, wool mulch. Pots were divided into 3 equal volume portions. Electroconductivity, as a measure of soluble salt (SS) level, was taken. All treatments had increasing SS levels with increasing pot height. Trt 2 had surface layer salt levels significantly higher than trt 1. `Victoria' trts 3,4,5 and 6 surface layers had significantly lower SS levels than trt 1 surface layers. `Crimson Fire' trt 4's surface layer had significantly lower SS levels than the surface layer of trt 1. Trts 4 and 6 bottom layers of both cultivars had significantly lower SS levels than all other treatments.

Abstract:
Objective: To determine patterns of adverse drug reactions (ADRs), including immediate drug hypersensitivity reactions (DHRs) and predictable ADRs, to thyroid replacement therapy (TRT). TRT is the treatment of choice for hypothyroidism. Levothyroxine (LT4) is among the most commonly prescribed medications in the United States, with over 70 million prescriptions annually. Documented immediate DHRs to TRT are rare, with only a few case reports. Methods: An 11-year (2008–2018) retrospective medical chart review of identified patients with self-reported allergy to TRT. ADRs to TRT were divided into immediate DHRs and predictable ADRs. Results: A total of 466 patients were included in our study. We found an overall incidence of ADRs to TRT of 0.3%. Median age was 61.2 years; 85.8% were women, and 94.4% were Caucasian. The principal indication for TRT was autoimmune hypothyroidism (73.6%), followed by postsurgical hypothyroidism (17.4%) and subclinical hypothyroidism (6.7%). Predictable ADR manifestations to TRT were reported more commonly than DHR manifestations (57.5% vs. 42.5%, respectively). The most frequently reported of the former were palpitations (16.4%), nausea/vomiting (9.3%), and tremor (6.3%), while rash (23.8%), hives (9.5%), and pruritus (7.1%) were the most common regarding the latter. Fifty-six percent of the patients with an ADR to TRT tolerated an alternative TRT presentation. Conclusion: In our cohort, the majority of self-reported allergies to TRT were due to predictable ADRs rather than an immediate DHR. Abbreviations: ADR = adverse drug reaction; DHR = drug hypersensitivity reaction; FDA = Food and Drug Administration; LT3 = liothyronine; LT4 = levothyroxine; SCAR = severe cutaneous adverse drug reaction; TRT = thyroid replacement therapy

Abstract:
A relevant contribution to sustainable development can be achieved by providing efficient solutions for heating buildings. The use of a heat pump taking heat from the bedrock with the help of a borehole heat exchanger is a common solution in Sweden to accomplish this. In situ measurement of the thermal conductivity of the ground by means of thermal response test is necessary for medium to large size installations to ensure proper sizing of the borehole system. This master thesis was done in cooperation with the department of geo energy at the company Bengt Dahlgren. The aim was to design a new compact thermal response test equipment, test it on a coaxial borehole heat exchanger and evaluate the test results and design a simple business model for using the equipment commercially. The company already had an equipment for thermal response tests, which formed the basis for the new equipment. A literature review was done to gain knowledge on thermal response test equipment, its components and borehole heat exchangers. Also, an evaluation of results from an earlier test of an 800 m deep borehole with a coaxial borehole heat exchanger was made. The project resulted in the construction of a new more compact equipment for thermal response tests with a new, improved heating solution. Two different business models based on renting out the equipment were designed. The equipment was tested on a 200 m deep borehole with a coaxial borehole heat exchanger. The test indicated a thermal conductivity of 2.46 𝑊𝑚∙𝐾 and a borehole resistance of 0.031 m∙KW.<br>En viktig del av en hållbar utveckling är energieffektiva lösningar för uppvärmning av byggnader. En vanlig lösning i Sverige är att använda en värmepump kopplad till en borrhålsvärmeväxlare och utnyttja berggrunden som värmekälla. I vissa fall är det motiverat att testa bergets värmeledningsförmåga med hjälp av ett termiskt responstest för att mer precist kunna dimensionera borrhålen. Denna mastersuppstas gjordes i samarbete med Bengt Dahlgren geoenergi. Arbetet syftade till att designa en kompakt utrustning för termiskt responstest, testa den nya utrustningen på en koaxial borrhållsvärmeväxlare och utvärdera testresultatet samt att designa en enkel affärsmodell för den nya utrustningen. Företaget hade sedan tidigare en utrustning för termiskt responstest, som låg till grund för designen av den nya. En litteraturstudie utfördes för att få mer kunskap om termisk responstestutrustning, dess komponenter och borrhålsvärmeväxlare. Dessutom gjordes en utvärdering av mätresultat från ett tidigare utfört test på ett 800m djupt borrhål med en koaxial borrhålsvärmeväxlare. Arbetet resulterade i en ny kompaktare utrustning för termiskt responstest med en ny smart lösning för uppvärmningen. Två olika affärsmodeller baserade på uthyrning av den nya utrustningen togs fram. Utrustningen testades på ett 200 m djupt borrhål med en koaxial borrhålsvärmeväxlare. Borrhålet visade en termisk värmeledningsförmåga på 2,46 𝑊𝑚∙𝐾 och ett borrhålsmotstånd på 0,031 m∙KW

Los errores asociados a cualquiera de esos parámetros en la interpretación de dichas pruebas mediante el uso del método tradicional de análisis, que considera una fuente lineal de calor (LHS), pueden ser hasta un 50% de sobrestimación para pruebas de relativa corta duración. Por ejemplo, el análisis de las simulaciones indica que, para un pilote de un metro de diámetro, es necesario realizar pruebas de más de 400 horas para obtener resultados confiables. Además, estos errores pueden ser acumulativos lo que puede aumentar la incertidumbre respecto a la estimación de los parámetros de diseño. Por lo anterior, se recomienda utilizar el conjunto de resultados generados en este estudio para estimar factores de corrección que deben aplicarse al interpretar los resultados de TRT en pilotes geotérmicos. Se espera que de esta forma los resultados presentados en este estudio permitan una correcta interpretación de los resultados de pruebas de terreno de corta duración, con el consiguiente beneficio en términos logísticos y económicos.

Por lo anterior, se recomienda utilizar el conjunto de resultados generados en este estudio para estimar factores de corrección que deben aplicarse al interpretar los resultados de TRT en pilotes geotérmicos. Se espera que de esta forma los resultados presentados en este estudio permitan una correcta interpretación de los resultados de pruebas de terreno de corta duración, con el consiguiente beneficio en términos logísticos y económicos.

Due to power system growth, it is possible that high voltage circuit breakers are not able to interrupt short-circuit currents and to withstand the TRy. This is a study for the reevaluation of 15 kV breaker performances at Companhia Hidroelétrica do São Francisco (CHESF) Angelim Substation. Digital simulations are carried out to compute the TRV parameters and to compare them with the standard ones. Alternatives are proposed to reduce the peaks and rate of rise of TRVs. It is shown that ZnO devices placed across the breaker terminals are very effective in reducing TRV peaks.<br>A forma de onda da tensão entre os terminais de disjuntores, quando da abertura de seus contatos, é definida como a tensão de restabelecirnento e nos seus instantes iniciais como a tensão de restabelecimento transitória (TRT). Considerando a expansão dos sistemas de potência, é possível que disjuntores de alta tensão não estejam mais adequados a interromper correntes de curto-circuito e suportar tensões transitórias. Neste trabalho é apresentado um estudo para a reavaliação dos disjuntores de 15 kV instalados na subestação Angelirn, pertencente a Companhia Hidroelétrica do São Francisco (CHESF). E realizado um estudo para três disjuntores, obtendo formas de onda da TRT através de simulações digitais. E feita uma análise dos parâmetros da TRT, comparando-os com os valores estabelecidos em normas técnicas. Alternativas para a redução do pico e da taxa de crescimento da TRT são propostas. A inserção de dispositivos de ZnO entre os terminais dos disjuntores produz redução significativa no pico da TRT.

Abstract:
The objective of this study is to examine historically the policies of theDirectorate of Documentary Programs (DDP) of the Turkish Radio Television Corporation (TRT). Since there is very little research about particular sphere of the public service broadcasting in Turkey it is aimed to contribute to this area of study. In the course of the study, historical conditions, structural factors, broadcasting policies, the conditions of public broadcasting of a country, and the role of individuals and the research methods applied in media studies were taken into consideration. Furthermore, governmental, military, lawful, economic, cultural policies, and policies emerging from the institutional mechanisms, and practices of individuals are illustrated regarding the different time periods. In this study, documentary research, observation, interview, and internet research were used as data gathering methods. Literature analysis, historical analysis and interpretative analysis were employed as methods of analysis. It is mentioned that the role of individuals in the analysis of media studies is not paid much attention, additionally, especially in Turkey, research conducted about media generally ignores the methods of ethnography, field research and interpretative analysis. In analyzing the policies of DDP, it is asserted that except for the structural effects, individuals/actors have also roles in shaping these policies. Furthermore, to examine the media, particularly television policies, it is maintained that there is a need to carry out analysis at the individual level by the help of conducting field research, applying methods of ethnography, and interpretative analysis in Turkey. Finally, it is claimed that to a large extend DDP have been under the effects of public broadcasting notion of Turkey, and there is a need for improving the institutional policies for the DDP to serve the public interest.

Full text
Abstract:
This thesis introduces intercultural broadcasting as an alternative and more accurate term to that of the strongly associated term to propaganda: international broadcasting. It challenges theories of public diplomacy. and public sphere by criticising public diplomacy as a term due to its abandonment of the core element of its process that is the power of ordinary citizens' unity, and provides the Arabs and Muslims as an example of a strong transnational public sphere due to the availability of the elements of unity amongst the roots of their shared values system which shapes their culture. This thesis examines the approaches of DW-TV Arabia and TRT-Etturkiyye in building bridges when targeting Arabic speaking audiences by analysing their dialogical programme content, as well as the overall programme genres. The uniqueness of this study comes from two points: it is the first research done by one of the targeted audience's members of the DW-TV Arabia and second, the TRT-Etturkiyye is relatively new and has changed its policies within the last year. This thesis argues that, before building bridges, with the international world, countries are to build inner bridges with immigrants of the same nationalities as the international targeted groups. For instance, the Arabs and Muslims have lots of values in common that present them as a transnational public sphere; thus, Germany can seize the largest group of its immigrants - who are Muslims as well - to benefit from its public diplomacy efforts worldwide. Also, this thesis records the reactions of both DW - TV Arabia and TRT - Etturkiyye towards the Arab Uprising of 2011, which forced both to create new programmes, invite new Arab guests and adopt new airing schedules. This thesis was built upon original data collected from surveying ninety-one participants, general thematic analysis of four weeks of DW-TV Arabia and TRT-Etturkiyye programmes, and detailed content analysis of the equivalent of twelve hours of episodes for each channel. The content analysis has been divided into two phases: the first was before the Arab Uprising of 2011 and the second afterwards. This thesis attempts to propose an innovative intercultural approach, considering the reality of this era's current international affairs. It outlines how an intercultural Arabic broadcaster targeting other cultural audiences should look.

Abstract:
On April 19, 2021, Ingenuity became the first helicopter to fly on Mars at Jezero Crater, completing a total of 72 flights by the end of its mission. The success of Ingenuity resulted in various research efforts to further exploreMars via vertical flight, including two optimized Ingenuity-sized helicopters proposed to retrieve samples for the 2028 Mars Sample Return mission. To aid in the design process for the two proposed Sample Retrieval Helicopters, both heritage and optimized, increased diameter rotors were tested at the NASA Jet Propulsion Laboratory in the 25-ft Space Simulator. Three test campaigns were performed using the Ingenuity rotors and optimized Sample Retrieval Helicopter (SRH) rotors for several rotor speeds, densities, configurations, and collectives to identify performance limitations. These three test campaigns included the Ingenuity Engineering Design Model 1 (EDM-1) with and without a cruciform box, Transonic Rotor Test (TRT) rig, and SRH Dual Rotor Test (DRT). Experimental setup, test matrix, data processing, data quality, and performance results for EDM-1, TRT, and DRT campaigns are presented and discussed. Experimental results from the test campaigns will aid in future experimental methods and validation efforts for planetary rotorcraft exploration.

Abstract:
1925 yılında mühendis John Logie Baird tarafından İngiltere’de icat edilen ve ilk yayını 1936’da yapılan televizyonun Türkiye’ye gelişi uzun bir zaman diliminin ardından gerçekleşmiştir. Ülkemizde televizyon denilince akla ilk gelen kurum Türkiye Radyo Televizyon Kurumu (TRT) olsa da aslında bu yolculuğun pek fazla bilinmeyen bir öncesi bulunmaktadır. Türkiye'de televizyon yayıncılığı, ilk kez 1952 yılında İstanbul Teknik Üniversitesi’nde başlatılmış olup, o günden bu yana hızla gelişerek büyük bir dönüşüm geçirmiştir. İlerleyen günlerde İstanbul Teknik Üniversitesi Televizyonu (İTÜ-TV) yayın akışı haftanın bir günü ve birkaç saat şeklinde düzenlenmiştir. 1960’larda televizyon alıcılarının sayısı artmış ve gündelik hayatta insanların birbirlerine televizyon izlemeye gittiği bir misafirlik dönemi başlamıştır. Bu kapsamda çalışmamızda Türkiye’de İTÜ-TV’den TRT’ye uzanan başlıklarıyla televizyonun tarihçesi, toplumsal hayata kattığı yenilik ve değişimler ve bu hikâyenin günümüz dijital çağındaki yeri TRT özelinde irdelenecektir. Bu amaçla, TRT’nin yayın hayatına başlangıcı ve gazetelerdeki yansıması arşiv taraması üzerinden incelenecek ve elde edilen haberler üzerinden içerik analizi yapılacaktır. TRT’nin günümüze dek geçirdiği değişim ve yenilikler üzerine yapılacak literatür taraması ile de dün ve bugün arasındaki bağın genel bir resmi çizilecektir. Türkiye’nin 100 yıllık birikimi içerisinde televizyon yayıncılığı alanında yerelden küresele damgasını vuran TRT’nin attığı adımların izini sürmek ve toplumsal yaşamdan başlayarak ülke tarihine etkilerini incelemenin iletişim literatürüne önemli bir katkı sunacağı öngörülmektedir.

Abstract:
Shallow geothermal energy already is and will be playing a major role in achieving the climate goals of the Paris Agreement. When designing geothermal energy systems, it is crucial to know the thermal conductivity of the underground as well as the thermal borehole resistance, besides further parameters. A thermal response test (TRT) is the method of choice for determining these values. Therefore, two teams in Sweden (Gehlin) and the USA (Spitler) developed TRT rigs in the 1990s. Since then, there have been numerous instructions and recommendations on how to execute testing, including the correct equipment, procedure, and evaluation of results, for example ISO 17628:2015, EN 17522:2023, VDI 4640 Blatt 5. However, currently there is no established method for testing TRT units and procedures to assess their functionality and quality. Therefore, an emulated borehole heat exchanger (E-BHE) for TRT unit quality assurance was developed and built at ZAE Bayern. It emulates the thermal behavior of a real borehole heat exchanger (BHE). Different borehole lengths, single and double U-pipes, as well as various underground properties, can be set. This allows for testing different TRT units within a short time span and with reproducible boundary conditions. The E-BHE uses the so-called EWS model by Huber. First tests underline the importance of using consistent models for TRT evaluation and BHE system design.

Este estudo tem como objetivo avaliar o desempenho com foco na TRT de um disjuntor isolado a gás SF6 de uma subestação de 69 kV localizada em uma instalação elétrica industrial. Este trabalho é baseado nos limites operacionais estabelecidos pelas normas IEEE Std C37.011-2011 e IEEE Std C37.04b-2008 para investigar o comportamento da TRT durante curto-circuito. As simulações foram executadas através do EMTP-ATP e do seu pré-processador gráfico ATPDraw. Os resultados mostram a necessidade de se realizar uma análise de TRT detalhada durante o desenvolvimento do projeto, de forma a garantir o dimensionamento adequado do disjuntor.

O crescente consumo de energia elétrica demanda que novas fontes de energia sejam inseridas no sistema elétrico brasileiro, gerando mudança no nível de curto-circuito das subestações já existentes. Sendo os disjuntores de potência afetados por essa mudança. Um dos fenômenos que sofre essa influência é a tensão de restabelecimento transitória (TRT). Se o disjuntor não suportar a TRT, ele pode reiniciar o curto-circuito promovendo prejuízos ao sistema.

Abstract:
Questo documento espone alcune considerazioni a proposito della promozione dei vaccini per il SARS-CoV-2 e delle strategie per garantirne un’equa distribuzione tra gli immigrati senza documenti residenti in Italia e, in particolare, a Roma. Quanto emerge dal caso italiano può essere in parte applicabile ad altri contesti in cui la somministrazione del vaccino è stata legata al dispositivo del “passaporto vaccinale”, ovvero il certificato COVID digitale dell'UE, in Italia Green Pass. Nell’organizzazione della campagna vaccinale alcune categorie sociali sono state identificate come “difficili da raggiungere” (hard to reach) e per cui è necessario immaginare interventi specifici.1 In questo testo si sceglie di parlare di persone razzializzate e illegalizzate poiché senza documenti per riferirsi a persone immigrate che non hanno cittadinanza, permesso di soggiorno e status di rifugiato. Questo documento esplora il contesto quotidiano delle vite delle persone illegalizzate e come l’esperienza della pandemia di COVID-19 abbia esacerbato le difficoltà che queste persone incontrano, 23 mettendo in luce il collegamento tra le vulnerabilità, consolidate ed emergenti, con la percezione dei vaccini. Si suggerisce come l’orientamento e la percezione dei vaccini si inseriscano all’interno dei contesti di vita delle persone, in cui molto spesso la priorità è data al sostentamento economico. In molti casi, l’accettazione della vaccinazione è motivata dalla necessità di continuare ad avere un lavoro retribuito piuttosto che a una preoccupazione connessa alla salute o a una fiducia nei confronti delle istituzioni sanitarie. Il seguente documento si pone l’obiettivo di esaminare come i vaccini possano essere distribuiti in modo equo e capace di aumentare la fiducia e i processi di inclusione nella società post-pandemica. Il testo si basa principalmente sulla ricerca etnografica e le testimonianze raccolte attraverso interviste e osservazioni con persone razzializzate e illegalizzate nella città di Roma, insieme a rappresentanti della società civile e operatori socio-sanitari tra dicembre 2021 e gennaio 2022. Questo documento è stato sviluppato per SSHAP da Sara Vallerani (Università di Roma Tre), Elizabeth Storer (LSE) e Costanza Torre (LSE). È stato revisionato da Santiago Ripoll (IDS, Università del Sussex), con ulteriori revisioni da parte di Paolo Ruspini (Università Roma Tre) ed Eloisa Franchi (Université Paris Saclay, Università di Pavia). La ricerca è stata finanziata dalla British Academy COVID-19 Recovery: G7 Fund (COVG7210058). La ricerca si è svolta presso il Firoz Lalji Institute for Africa, London School of Economics. La sintesi è di responsabilità di SSHAP.
