Background: Bladder Cancer remains a major health burden, with over 10,000 new cases diagnosed annually in the UK. Around 80% of all cases are diagnosed as Non-Muscle Invasive Bladder Cancer (NMIBC), and 75% of patients have cancer recurrence and progression within 10 years. Patients with NMIBC are treated by Trans-Urethral Resection of the Bladder Tumour (TURBT), with approximately 8% of patients subsequently developing post-operative complications, such as bleeding, pain and infection. Currently, there is limited literature on the ‘normal’ pathophysiological response to TURBT for NMIBC, and predictors for post-operative complications. The aim of this clinical-pilot observational study was to evaluate changes in routine blood tests following TURBT. The objectives were to identify the ‘normal’ pathophysiological response after TURBT. Methods: 34 consecutive patients aged between 57–94 years (median age: 72), scheduled for TURBT were recruited after written informed consent. Venous blood samples were collected from patients pre operatively (baseline), and post operatively at the following time points; 30 minutes, 120 minutes and 240 minutes post-operatively. Results: Following TURBT, significant decreases were seen in several haematological and biochemical markers: haemoglobin (p<0.01), platelets (p<0.01), erythrocytes (p<0.01), haematocrit (p<0.01), plasma viscosity (p=0.002) activated partial thromboplastin time (p= 0.004), fibrinogen (p<0.01), potassium (p<0.01), globulin (p=0.047), alkaline phosphatase (p=0.001), and urea (p=0.001). Furthermore, significant increases were observed in numerous haematological and biochemical parameters: leukocytes (p=0.049), neutrophil count (p=0.022), prothrombin (p=0.014), bilirubin (p= 0.004), and alanine transaminase (p=0.004). Conclusion: Significant changes to several routine blood tests occur following TURBT, and in general, it appeared that the most noticeable changes occurred between 30 and 120 minutes post-operatively. This clinical-pilot study may therefore provide a sound platform to undertake larger studies, to fully establish the effect of TURBT on routine blood tests, and could ultimately provide valuable information for doctors that may help with the clinical management of patients.

ISLAMIC PHILOSOPHICAL TRADITION: Knowledge and Man’s Path To God
Authors: Abdullah Wawan
Published: May 2023

Islamic civilization has given birth to no less than 300 philosophers, therefore every Islamic or Arabic philosophy has a special tradition that no other tradition has. The philosophical tradition in Islam is a creative work born from the worldview of Islam. It is a system of beliefs, thoughts and values, which is projected by the word of God through tafaqquh, bayan, interpretation, takwil, and is developed in the Islamic scientific tradition. Islamic philosophy grows from revelation and then develops within scientific traditions, such as fiqh, interpretation, kalam, and hadith. Islamic rational-philosophical thought was born not from outsiders but from its holy book, namely the Koran, especially in relation to efforts to adapt the teachings of the text to the realities of everyday life. There are at least three models of formal study which turn out to have philosophical relevance. Among other things, (1) the use of takwîl. (2) musytarak and (3) the use of qiyâs (analogy). Al Kindi has introduced new problems in Islamic thought and left behind philosophical problems that persist today: (1) the creation of the universe, how it came about, (2) the immortality of the soul, what it means and how to prove it, and (3) knowledge of God, what does astrology have to do with it and how did it happen. There are two reasons it is called Islamic philosophy.

Medições de irradiância solar espectral trazem um maior detalhamento sobre o comportamento da radiação solar, sendo importantes na análise da geração fotovoltaica. Neste trabalho, foi realizada uma caracterização do espectro da irradiância global horizontal para a cidade de Petrolina, utilizando mais de 100 mil medições da irradiância espectral com alta resolução (1 nm) na faixa de comprimento de onda de 300 a 1700 nm, obtidas entre setembro de 2018 a julho de 2021. Foi analisado o impacto da massa de ar na intensidade e no formato da distribuição espectral da irradiância solar de céu claro. Além disso, foi obtida a proporção das componentes da radiação ultravioleta, luz visível e infravermelha do espectro local e como elas são afetadas com a massa de ar. Através dos espectros observados, foi possível também analisar o comportamento médio da distribuição espectral da irradiância sob efeito de cloud enhancement. Além da caracterização do espectro local, simulações da irradiância espectral obtidas com o software SMARTS2 foram validadas para momentos de céu claro. Foi observado que o erro do modelo SMARTS2 aumenta com a massa de ar e possui valores mais altos para a faixa de radiação ultravioleta. O valor da raiz do erro quadrático médio normalizado pela média das observações (nRMSE) para as simulações do SMARTS2 foi acima de 10 %, porém, ao considerar o valor de energia integrado total e seu impacto na energia absorvida pelas tecnologias fotovoltaicas de silício monocristalino, silício amorfo, telureto de cádmio e módulos formados pelo polímero orgânico P3HT:PCBM, o valor do nRMSE ficou em torno de 3 %.

O desempenho dos sistemas fotovoltaicos é afetado pelas condições ambientais reais, como a irradiância solar, a temperatura e a sujidade, nesta ordem de relevância. A sujidade descreve a deposição de poeira e outros contaminantes na superfície do módulo fotovoltaico, que atenuam a irradiância solar ao absorver ou refletir a luz solar, causando perdas de rendimento e podendo contribuir para a degradação do módulo fotovoltaico. Este estudo tem como objetivo avaliar a composição físico-química da sujidade depositada naturalmente em módulos FV instalados nas cidades de Medianeira, Pato Branco, Campo Mourão e Curitiba, do estado do Paraná. Análises morfológicas e elementares da sujidade coletada foram realizadas usando Microscopia Eletrônica de Varredura (MEV) e Espectroscopia de Energia Dispersiva (EDS). A morfologia das amostras indica que as partículas de sujidade têm diferentes formas e tamanhos (1 a 58 µm), o que influencia diretamente na adesão da superfície do módulo fotovoltaico. Foram observados mecanismos de sujidade que ampliam a adesão à superfície como a cimentação e a aglomeração de partículas devido a interação com água. Na análise elementar, o oxigênio é o elemento dominante da composição das amostras, seguido pelo ferro, silício, alumínio, cálcio, estanho, magnésio, titânio, bário, potássio, enxofre, flúor, cobre, sódio, cloro, fósforo e manganês. Portanto, o entendimento das características físico-química da sujidade é importante para compreender a fonte da aderência e buscar os métodos apropriados de limpeza, assim como o desenvolvimento de revestimentos autolimpantes, podendo auxiliar na identificação da sua procedência e indicar o movimento das partículas em um campo elétrico, que pode estar associado a degradação do módulo.

As células solares bifaciais fabricadas em lâminas de silício cristalino tipo n apresentam potencial de obtenção de maior eficiência e bifacialidade próxima a um. Com este foco, o objetivo deste artigo é analisar a influência do método de formação do emissor produzido na mesma etapa térmica que o campo retrodifusor nos parâmetros elétricos de células solares bifaciais base n com estrutura PERT e passivação das superfícies com SiO2. Foi utilizado o método de spin-on e a difusão do boro foi realizada em forno convencional, seguida da difusão do fósforo com POCl3. Variou-se a temperatura de difusão de boro e analisou-se a resistência de folha do emissor e do campo retrodifusor dopado com fósforo bem como a influência nos parâmetros elétricos das células solares bifaciais. Verificou-se que a resistência de folha do emissor de boro diminuiu de (116 ± 6) Ω/sq para (64 ± 2) Ω/sq com o aumento da temperatura de difusão de boro de 940 °C a 980 °C. Porém, a resistência de folha do campo retrodifusor de fósforo aumentou, indicando que a difusão de boro afeta a região dopada com fósforo. As maiores eficiências, de 15,3% e 15,5 % com irradiância no emissor e campo retrodifusor, respectivamente, foi alcançada com a temperatura de difusão de 960 °C. Neste dispositivo, a bifacialidade foi de  0,987. Constatou-se que a tensão de circuito aberto foi maior com irradiância no emissor, independente da temperatura de processamento. Também se concluiu que a tensão de circuito aberto e o fator de forma cresceram até a temperatura de processamento de 960 °C, independente do modo de iluminação. Porém, a densidade de corrente de curto-circuito com irradiância no emissor tendeu a diminuir, devido ao aumento da recombinação dos portadores de carga minoritários. O fator de forma foi o parâmetro elétrico que mais influenciou na eficiência.

Published: May 2023

Cidades ao redor do mundo, inclusive cidades brasileiras, estão investindo cada vez mais em sistemas de mobilidade elétrica, visando reduzir o impacto do setor de transportes no aquecimento global. Desde 2017, o eBus 100% elétrico do laboratório Fotovoltaica UFSC opera em Florianópolis, associado a um sistema fotovoltaico e um sistema de armazenamento de energia com baterias (BESS) de segunda vida. O objetivo deste trabalho é avaliar a viabilidade econômica do sistema do eBus em relação à um ônibus a diesel. Para isso, foram definidos cenários com e sem BESS, com diferentes tempos de vida útil para os ônibus, e analisadas 3 taxas mínimas de atratividade. O melhor resultado mostrou um Valor Presente Líquido (VPL) positivo de R$ 776.936,30, uma Taxa Interna de Retorno (TIR) de 19,56%, e um payback descontado de 4 anos e 11 meses. Por fim, foi realizada uma análise de sensibilidade para avaliar a variação nos indicadores financeiros ao alterar aspectos chave como o custo inicial do ônibus elétrico, o preço do diesel e o preço do BESS. Os resultados da análise de sensibilidade evidenciaram que o sistema de ônibus elétrico associado a energia solar é viável economicamente e, no melhor cenário, o tempo de retorno do investimento é de pouco mais de 2 anos com uma TIR de 58,53%. De forma geral, o BESS não representou um investimento interessante nas condições de contorno estabelecidas, pois mesmo considerando a redução no custo inicial do sistema este não resultou em melhoras significativas nos indicadores comparado aos outros cenários.

Authors: Muhammad Arif
Published: May 2023

The aim of this paper was to find the relationship between leadership and its impact on quality of healthcare. Survey approach using questionnaire was used for data collection. Population of the study was from Qassim health sector employees. A total of 200 completed questionnaires were collected back and used in the analysis in this study. Correlation analysis and regression analysis were used to test hypotheses. It was found that all the predictors and criterion have moderate and positive relationship. Likewise, there is significant impact of leadership found on quality of healthcare in Saudi Arabia; finding are consistent with that previous studies. Based on findings, the study suggests that participative style of the leader not only encourage the people to give their input in decision making and formulation of plans but also play greater role in implementation too. Therefore, friendly, accommodative, democratic, encouraging, and liberal work environment may be created by management of the hospitals because such kind of an environment increase the level of performance and advantageous in materializing the predefined objectives of quality management, that also supplements better healthcare outcomes. Future researcher can conduct studies with larger sample to generalize the findings since this study used a small sample size only from one region.

The colonialism and tyranny of the Palestinian people after the silence of the large-scale countries and the limited support of the Palestinian National Authority or the rather westernized capacity of the people, the presence of various types of non-governmental organizations or non-governmental organizations (NGOs) carries out humanitarian assistance activities for vulnerable groups. This. The main objective of this research is to recognize the nature of humanity and the contribution of Malaysian Humanitarian NGOs to the Palestinian Humanitarian issue. Based on a qualitative approach, a virtual meeting was held with three members of the Safe Palestine NGO. The selection of this NGO was based on special assistance to the Palestinians and active involvement since the establishment of the organization. The study shows that there are various forms of assistance for humanity, Safe Palestine, through projects involving the economic, educational, social, health, agricultural, and infrastructure sectors that have successfully contributed to the health of people in the world. Active involvement through activities in Malaysia has made awareness of the Palestinian issue among the Malaysian community. However, Safe Palestine projects and activities are considered to be religious. The essence of the Palestinian issue is equated as humanism and not religion solely so that all ethnic groups, regardless of religious background, can go hand in hand in refuting Israel's misanthropy.
Cosmopolitanism or Multiculturalism? Towards an Anti-Colonial Reading
Authors: Sefa Dei George J.
Published: May 2023

Using Multiculturalism as an entry point, the paper interrogates conventional ideas and themes of Cosmopolitanism from an anti-racist and anti-colonial read. The discussion is informed by how the anti-racist and anti-colonial lens has shaped an understanding of multiculturalism and its convergences and divergences with Cosmopolitanism. My goal is to advance a rethinking' cosmopolitanism' from an Indigenist anti-colonial democratic lens highlighting a philosophy of educational practice geared towards new educational futurities for particularly [but not exclusively] Black, Indigenous and racialized bodies in the school system. It is argued that cosmopolitanism is about Land and relationships. This offers possibilities of learning from the ‘geographies of schooling’. The pedagogies of the Land, for example, require examining the narratives and encounters taking place in these 'geographies of schooling' to unravel colonial structures of education and ways we validate contending or competing for multiple knowledges for decolonizing and anti-colonizing education. In the context of the cosmopolitan, institutions like schools, as carceral projects, must acknowledge that anti-Black racism is ‘pervasive throughout the system’ and not simply assert rhetorically that 'anti-Black racism has no place in our school'! Critical educators in their practice of teaching training and preparation, must be able to name institutional silences, erasures, negligence, and complicities around race, anti-Black racism, and Indigeneity in order to create inclusive learning communities and schools as ‘working communities’.
Cosmopolitanism and Decolonization: Contradictory Perspectives on School Reform to Advance Reconciliation with Indigenous Peoples
Authors: Wotherspoon Terry , Milne Emily
Published: May 2023

Canadian school jurisdictions have taken steps to accommodate objectives to advance cosmopolitan education reflecting principles such as global citizenship, compassion, tolerance, responsibility, and respect within school curricula and educational practice. At the same time, a parallel set of reconciliation-related educational reforms, aligned with the Calls to Action that accompanied the 2015 Truth and Reconciliation Commission final report, have also gained urgency. Elements of reconciliation processes complement visions of cosmopolitanism, including objectives to foster dialogue and understanding between groups and advancements towards more holistic orientations to pedagogy and knowledge. However, conceptually and in practice, several tensions emerge, especially in a context in which educational priorities are contested. In this paper, we explore these connections and tensions with reference to findings from our research examining public perspectives on educational reforms to support reconciliation.
Thinking Relationally and Pedagogically about Commemoration: A Critical Inquiry into Charlottetown’s Macdonald Statue
Authors: Johnson Kay
Published: May 2023

In this article, I provide a critical reading of the now-removed statue of Sir John A. Macdonald in Charlottetown, Prince Edward Island, Canada. I bring together my own experience visiting the statue with understandings from Indigenous scholarship and public pedagogy theorizing to think about commemorations as public pedagogies that are foremost relational. I consider how the Macdonald statue works narratively, discursively, and as a site of embodied encounter to create a harmful relationality. Thinking relationally, and pedagogically, about colonial statues suggests possibilities not only for understanding how these commemorative practices produce bad relations but also for envisioning and enacting good relations.

It explores Neurodiversity, an equity imperative, as critical to shifting the culture of teaching and learning by offering a potential framework for overcoming historical systemic barriers to inclusion. Next, it discusses shared attributes of epidemiology of teacher beliefs, neuroscience and Teacher self-study as potential foundational components, complimenting Neurodiversity paradigms. Lastly, a proposed theoretical framework and suggested future research which could lead to the development of an inclusive pedagogy. Education is the cornerstone to fostering talent and creativity of each individual and it is only when the system is truly inclusive of all human diversity, can individuals flourish developing their talents.
Asynchronous Posting and Reading both Reflect Communities of Inquiry
Authors: Kaur Magon Juss , Shore Bruce M.
Published: May 2023

This descriptive case study explored the presence of a community of inquiry among 4492 secondary learners enrolled in four asynchronous online discussion forums over a full year. The forums (Ethics and Philosophy, Reading, Astronomy and Space, and General Debates, among others not studied) were external to the students’ schools across England. The data had been archived by the sponsoring organisation. We coded 3,113 transcribed messages posted or read by students using Garrison’s Community-of-Inquiry model and coding tools--addressing social, cognitive, and teaching presence within the interactions, plus 307 online questionnaire responses from a cross-section of participants about reasons for posting or not and overall participation plus representative quotes were also presented. Of the 4,492 enrollees, 1,523 (34%) posted messages, 1,748 (39%) only read or viewed posts, and 1,222 (27%) never logged in. This posting rate was almost quadruple the rate previously reported for online communities. Participation was also wider. The largest numbers of messages reflected community-of-inquiry social presence, especially following-up others’ messages. Cognitive presence particularly reflected sharpening thinking skills and knowledge. Teaching presence included asking stimulating questions and providing encouragement. Students who only viewed others’ messages logged in frequently, reported stimulation and strong benefits in learning skills, and only occasionally reported shyness or intimidation. Active student participation and engagement include more than posting messages; they also include reading or viewing others’ posts. Community of inquiry was highly evident in the asynchronous, secondary, online setting. An asynchronous platform, with effective teaching presence, can support important qualities of a community of inquiry.

The subject of the study is the visual aspect in historical and anthropological study of the population and ethnic groups of the Yakut Autonomous Soviet Social Republic, implemented in the course of field research by employees of the Research Institute of Language and Culture at the Council of People's Commissars of the Yakut Autonomous Soviet Social Republic (1935) and the Yakut Museum of Local Lore by Em. Yaroslavsky name. In the 1930s-1940s through the joint efforts of the staff the Institute and the Museum, a new array of visual sources is being formed that characterizes the traditional everyday life of the population and ethnic groups living on the territory of the republic. The purpose and objectives of the article are determined by the need for a special review the corpus of visual sources, and in it a special analysis of the author's photographs collected as part of expeditions by employees of the first research institute and the local history museum of the Yakut Autonomous Soviet Socialist Republic during the period under study. The methodology for studying visual heritage is based on an interdisciplinary approach to the study of traditional culture and its objective world, as well as expeditionary photo projects as phenomena the visual culture of their time.

In the article, the authors pays attention to issues related to the professional training of cadets, trainees, as well as employees undergoing initial training and retraining for joint actions when performing assigned operational and combat tasks. The legal and tactical aspects of the implementation of this training at the current stage of the development of the training program for internal affairs bodies in educational organizations of the Ministry of Internal Affairs of Russia are reflected. The approaches of scientific research conducted by some authors in this direction are considered and analyzed, as well as a number of recommendations for improving the system of teaching tactics of joint actions when working in units (groups) with offenders are presented.   Summing up the general line under all of the above, it should be noted that such an aspect of training as working out joint actions by cadets and trainees when working with offenders is currently not implemented at the proper level within the framework of the general training program of the Department of Internal Affairs. In our opinion, it is necessary to integrate the positive experience of territorial divisions on the example of such events as simulators, often practiced in traffic police and PSP units, which consist in modeling the most popular situations of collision with offenders. In our opinion, the variability of approaches to teaching tactics of actions of cadets and trainees when working with offenders can be formed individually by each teacher, depending on the type and topic of the training session.
Reform of serfdom and its impact on legal consciousness and legal culture of peasants
Authors: Arutyunov Erik Karenovich
Published: May 2023

The author believes that the abolition of serfdom had a "colossal" significance for the formation of new forms of legal consciousness and legal culture of the peasant population. These categories influenced the historical formation of the rule of law and the transition to a new form of government. The paper states that insufficient attention has been paid to the issues of legal consciousness and legal culture of peasants in the scientific community, which led to a narrow circle of approaches to the study of peasant life and psychology. The subject of the study is the patterns of formation and functioning of the legal consciousness and legal culture of the peasant after the abolition of serfdom. The author used the works of scientists in the field of law, philosophy and history to form more informed conclusions on the research topic. The purpose of the work is to analyze the formation and development of legal consciousness and legal culture of the population of the Russian Empire in the nineteenth century after the abolition of serfdom.
Self-organization of songbird neural sequences during social isolation

Behaviors emerge via a combination of experience and innate predispositions. As the brain matures, it undergoes major changes in cellular, network, and functional properties that can be due to sensory experience as well as developmental processes. In normal birdsong learning, neural sequences emerge to control song syllables learned from a tutor. Here, we disambiguate the role of tutor experience and development in neural sequence formation by delaying exposure to a tutor. Using functional calcium imaging, we observe neural sequences in the absence of tutoring, demonstrating that tutor experience is not necessary for the formation of sequences. However, after exposure to a tutor, pre-existing sequences can become tightly associated with new song syllables. Since we delayed tutoring, only half our birds learned new syllables following tutor exposure. The birds that failed to learn were the birds in which pre-tutoring neural sequences were most ‘crystallized,’ that is, already tightly associated with their (untutored) song.

Allosteric modulation of G protein-coupled receptors (GPCRs) is a major paradigm in drug discovery. Despite decades of research, a molecular-level understanding of the general principles that govern the myriad pharmacological effects exerted by GPCR allosteric modulators remains limited. The M4 muscarinic acetylcholine receptor (M4 mAChR) is a validated and clinically relevant allosteric drug target for several major psychiatric and cognitive disorders. In this study, we rigorously quantified the affinity, efficacy, and magnitude of modulation of two different positive allosteric modulators, LY2033298 (LY298) and VU0467154 (VU154), combined with the endogenous agonist acetylcholine (ACh) or the high-affinity agonist iperoxo (Ipx), at the human M4 mAChR. By determining the cryo-electron microscopy structures of the M4 mAChR, bound to a cognate Gi1 protein and in complex with ACh, Ipx, LY298-Ipx, and VU154-Ipx, and applying molecular dynamics simulations, we determine key molecular mechanisms underlying allosteric pharmacology. In addition to delineating the contribution of spatially distinct binding sites on observed pharmacology, our findings also revealed a vital role for orthosteric and allosteric ligand–receptor–transducer complex stability, mediated by conformational dynamics between these sites, in the ultimate determination of affinity, efficacy, cooperativity, probe dependence, and species variability. There results provide a holistic framework for further GPCR mechanistic studies and can aid in the discovery and design of future allosteric drugs.

Our brain is continuously challenged by daily experiences. Thus, how to avoid systematic erasing of previously encoded memories? While it has been proposed that a dual-learning system with ‘slow’ learning in the cortex and ‘fast’ learning in the hippocampus could protect previous knowledge from interference, this has never been observed in the living organism. Here, we report that increasing plasticity via the viral-induced overexpression of RGS14414 in the prelimbic cortex leads to better one-trial memory, but that this comes at the price of increased interference in semantic-like memory. Indeed, electrophysiological recordings showed that this manipulation also resulted in shorter NonREM-sleep bouts, smaller delta-waves and decreased neuronal firing rates. In contrast, hippocampal-cortical interactions in form of theta coherence during wake and REM-sleep as well as oscillatory coupling during NonREM-sleep were enhanced. Thus, we provide the first experimental evidence for the long-standing and unproven fundamental idea that high thresholds for plasticity in the cortex protect preexisting memories and modulating these thresholds affects both memory encoding and consolidation mechanisms.

The consequences of aneuploidy have traditionally been studied in cell and animal models in which the extrachromosomal DNA is from the same species. Here, we explore a fundamental question concerning the impact of aneuploidy on systemic metabolism using a non-mosaic transchromosomic mouse model (TcMAC21) carrying a near-complete human chromosome 21. Independent of diets and housing temperatures, TcMAC21 mice consume more calories, are hyperactive and hypermetabolic, remain consistently lean and profoundly insulin sensitive, and have a higher body temperature. The hypermetabolism and elevated thermogenesis are likely due to a combination of increased activity level and sarcolipin overexpression in the skeletal muscle, resulting in futile sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA) activity and energy dissipation. Mitochondrial respiration is also markedly increased in skeletal muscle to meet the high ATP demand created by the futile cycle and hyperactivity. This serendipitous discovery provides proof-of-concept that sarcolipin-mediated thermogenesis via uncoupling of the SERCA pump can be harnessed to promote energy expenditure and metabolic health.
