Impact of Soiling on Performance and Cleaning Optimization of a 2.5 MWp Solar PV Plant in Pune, India
Authors: Kartik Kapoor  , Muthusamy Eswaramoorthy , P.G Nikhil , Kumar Goyal Ravi 
Published: February 2025

The soiling pattern of PV plants needs to be studied for the proper utilization of solar energy as it creates a partial blockage of radiation and hence reduces power generation. The pattern of soil deposition varies from one location to another location. A large number of studies were carried out for a dry season to measure per day soiling rate. This research article investigates soiling pattern of a varied weather location i.e., Pune, India. Ambient temperature is less with high chances of precipitation and wind speed as compared with other locations of India. To measure the change in performance of PV plant around the year, a 2.5-MWp grid-tied PV plant having the location coordinates 18.52°N 73.85 °E was investigated. Various performance parameters i.e., Voc and Isc change with temperature, performance ratio, soiling ratio, and soiling loss percentage are evaluated. The results indicate that prediction of the exact value of the soiling rate is not possible due to seasonal variation. An average monthly soiling rate of 10.28 % is estimated based on observed data for the dry season. The cleaning activity is suggested on and after the 8th or 18th day with water or mechanical cleaning with water for avoiding financial losses to the college. Further, a micro-texture sheet can be laminated over the PV module with proper earthing to minimize the static charge formation for reducing the collection of dust.

Abstract. This study describes the coupling of the process-based Model of Early Diagenesis in the Upper Sediment with Adaptable complexity (MEDUSA version 2) to an existing ocean biogeochemistry model consisting of the Finite-volumE Sea ice–Ocean Model (FESOM version 2.1) and the Regulated Ecosystem Model (REcoM version 3). Atmospheric CO2 in the model is a prognostic variable which is determined by the carbonate chemistry in the surface ocean. The model setup and its application to a pre-industrial control climate state is described in detail. In the coupled model, 1390 PgC is stored in the top 10 cm of the bioturbated sediment, mainly as calcite, but also as organic matter (10 %). In the coupled simulation, atmospheric CO2 stabilizes at ∼295 ppm after 2000 years, in line with the CO2 level expected from the climate forcing conditions. Sediment burial of carbon, alkalinity, and nutrients in the coupled simulation is set to be compensated by riverine input. The spatial distribution of biological production is altered depending on the location of riverine input and reduction in sedimentary input, as well as the strength of local nutrient limitation, while the global productivity is not affected substantially. With this coupled ocean–sediment system the model is able to simulate the carbonate compensation feedback under moderate perturbation of CO2 in the atmosphere.

Este artigo propõe uma reflexão sobre a Pedagogia denominada Artes em Sociais Aprendizagens: ASAS. A partir dos escritos de Paulo Freire (2016), de suas críticas ao modelo “bancário de educação”, assim como, de sua propositura de uma educação libertadora, articuladas com as reflexões de Jorge Larrosa (2022) sobre o conceito de experiência e também aludindo ao que Marcus Pereira (2012) denominou como Habitus Conservatorial, empreende-se, esta reflexão sobre pedagogia das Artes em Sociais Aprendizagens (ASAS), tal como apresentada por Abreu (2024). As ASAS propõem um novo modelo pedagógico para o ensino das artes na educação básica, ao buscar romper com a educação bancária e o Habitus Conservatorial. Para tanto, as ASAS se fundamentam na experiência, tal qual definida por Larrosa, como elemento central de todo o processo de aprendizagem. Nesta abordagem a ênfase é conferida à compartilha de saberes, realizada em meio a relações horizontais e dialógicas, de modo a valorizar as experiências singulares de cada sujeito. O objetivo central das ASAS está em desenvolver, de forma integral, o ser humano, em todas suas potencialidades, integrando as dimensões cognitivas, sensíveis, emocionais e éticas. Para tanto, as ASAS buscam romper com a lógica hierarquizante e compartimentalizada do campo artístico e educacional, de modo a promover uma visão democrática e ampla da educação artística. Esta pedagogia se assenta na compreensão de que todos os envolvidos são, assim, sujeitos ativos do processo, estimulando o desenvolvimento da criatividade, da criticidade e da reflexão. Nas conclusões deste trabalho são apresentados argumentos que embasam a afirmação de que as ASAS oferecem um caminho viável para a transformação social e o autocultivo, por meio da construção de um ambiente educacional mais justo, emancipador e criativo, evocando a imagem de um voo coletivo, no qual todos aprendem em comunhão, buscando uma sociedade mais humana e solidária, através das artes.
Novel association between graft rejection and post-transplant malignancy in solid organ transplantation
Authors: Kim Hye Sung , Woo Wongi , Choi Young-Geun , Bharat Ankit , Chae Young Kwang 
Published: February 2025

BACKGROUND
Advancements in immunosuppressive therapies have improved graft survival by enhancing graft tolerance and preventing organ rejection. However, the risk of malignancy associated with prolonged immunosuppression remains a concern, as it can adversely affect recipients’ quality of life and survival. While the link between immunosuppression and increased cancer risk is well-documented, the specific interactions between graft rejection and post-transplant malignancy (PTM) remain poorly understood. Addressing this knowledge gap is crucial for devising immunosuppressive strategies that balance rejection prevention with cancer risk reduction.
AIM
To investigate whether immunosuppression in PTM reduces rejection risk, while immune activation during rejection protects against malignancy.
METHODS
We analyzed data from the United Network for Organ Sharing’s Organ Procurement and Transplantation Network database (1987–2023) on adult, first-time, single-organ transplant recipients with no prior history of malignancy (in donors or recipients). Landmark analyses at 1, 2, 3, 5, 10, 15, and 20 years post-transplant, Kaplan–Meier analyses, and time-dependent Cox proportional hazards regression models, each incorporating the temporal dimension of outcomes, assessed the association between rejection-induced graft failure (RGF) and PTM. Multivariate models were adjusted for clinical and immunological factors, including immunosuppression regimens.
RESULTS
The cohort included 579905 recipients (kidney: 386878; liver: 108390; heart: 45046; lung: 37643; pancreas: 1948) with a mean follow-up of 7.3 years and a median age of 50.6 ± 13.2 years. RGF was associated with a reduction in PTM risk across all time points [hazard ratio (HR) = 0.07-0.20, P < 0.001], even after excluding mortality cases. Kidney transplant recipients exhibited the most pronounced reduction (HR = 0.22, P < 0.001). Conversely, among recipients with PTM, RGF risk decreased across all time points up to 15 years after excluding mortality cases (HR = 0.49–0.80, P < 0.001). This risk reduction was observed in kidney, liver, heart, and lung transplants (HRs = 0.90, 0.21, 0.21, and 0.18, respectively; P < 0.001) but not in pancreas transplants.
CONCLUSION
RGF reduces PTM risk, particularly in kidney transplants, while PTM decreases RGF risk in kidney, liver, heart, and lung transplants.

BACKGROUND
Cytomegalovirus (CMV) prophylaxis with valganciclovir and ganciclovir is associated with elevated neutropenia and leukopenia risk in kidney transplant recipients, although the impact of these events on healthcare resource utilization (HCRU) and clinical outcomes is unclear.
AIM
To quantify clinical events and HCRU associated with neutropenia and leukopenia among adults receiving valganciclovir and/or ganciclovir post-kidney transplantation.
METHODS
Adult kidney transplant recipients receiving valganciclovir and/or ganciclovir prophylaxis were identified in the TriNetX database from 2012 to 2021. Patient characteristics were evaluated in the 1-year period pre-first transplant. HCRU and adjusted event rates per person-year were evaluated in follow-up year 1 and years 2-5 after first kidney transplantation among cohorts with vs without neutropenia and/or leukopenia.
RESULTS
Of 15398 identified patients, the average age was 52.39 years and 58.70% were male. Patients with neutropenia and/or leukopenia had greater risk of clinical events for CMV-related events, opportunistic infections, use of granulocyte colony stimulating factor, and hospitalizations (relative risk > 1 in year 1 and years 2-5). Patients with vs without neutropenia and/or leukopenia had higher HCRU in year 1 and years 2-5 post kidney transplantation, including the mean number of inpatient admissions (year 1: 3.47 vs 2.76; years 2-5: 2.70 vs 2.29) and outpatient visits (48.97 vs 34.42; 31.73 vs 15.59, respectively), as well as the mean number of labs (1654.55 vs 1182.27; 622.37 vs 327.89).
CONCLUSION
Adults receiving valganciclovir and/or ganciclovir prophylaxis post-kidney transplantation had greater risk of neutropenia and/or leukopenia, which were associated with higher clinical event rates and HCRU up to 5 years post-transplantation. These findings suggest the need for alternative prophylaxis options with lower myelosuppressive effects to improve patient outcomes.

Nascimento a três: o pai no parto
Authors: Matos Mariana Gouvêa de , Magalhães Andrea Seixas 
Published: February 2025

O presente trabalho é parte de pesquisa mais ampla sobre experiências de pais e mães acerca do parto a partir de um estudo de caso coletivo (Stake, 2016) no qual foram analisados 30 relatos de parto publicados em blogs pessoais sobre experiências de gestação, parto e parentalidade, sendo 15 escritos por mulheres e 15 por homens. O objetivo deste artigo é discutir a participação do pai no parto. Os resultados apontam para a presença do pai no parto como asseguradora para a mulher e fortalecedora da relação conjugal. Por outro lado, a ausência paterna por normas do hospital, além de infringir a legislação, pode promover vivências de desamparo para a mulher e dificultar o andamento do trabalho de parto. Concluímos que a decisão sobre a presença do pai no parto deve ser tomada em conjunto pelos membros do casal, considerando as possibilidades e necessidades de cada um. Para aqueles casais cujos membros desejam, a presença paterna pode contribuir enormemente para o processo de elaboração da transição para a parentalidade.

Published: February 2025

The COVID-19 pandemic caused economic and social disruptions in Nigeria forcing the government to implement certain containment measures to reduce the severity of the epidemic. The containment measures triggered economic recession leading the government into a policy dilemma of choosing between reducing fatalities and stabilizing the economy. Thus, the key objectives of this research focused on analyzing the macroeconomic impact of COVID-19 pandemic on the Nigerian economy and evaluating the effectiveness of government containment policies in reducing the infection rates and their attendant trade-off with economic performance. To achieve the objectives, this study implemented the SIR-macro model to study the interaction between agents’ economic decisions and COVID-19 epidemic. The parameters of the models were calibrated based on the characteristics of Nigeria’s economic structure to analyze the implications of containment policies on the severity of economic recession and the dynamics of the epidemics. The result showed that the population of those infected peaked at 5.56% in week 34 while economic activities dipped by 5.18% in the no-containment model. However, in the benchmark containment model with treatment and vaccination, the population of the infected peaked at 3.09% in week 42 while economic activities declined by 22.32%. The study found that government containment policies were effective in reducing the severity of the epidemic in terms of the spread of the disease and number of deaths. The containment policies on the other hand exacerbated the severity of the economic recession. Given the findings, it was concluded that the predictions of the model are qualitatively sufficient in explaining the macroeconomic outcomes in Nigeria during this period. The study suggests that government should consider the socio-demographic characteristics of the country in the selection of policies in an epidemic condition. The government should strengthen the health care system with adequate infrastructure to prevent large case fatalities.

Introduction: Mechanical power establishes the amount of energy per unit time transferred from the ventilator to the respiratory system. Its usefulness as a predictor of death has been demonstrated in COVID-19 or acute respiratory distress syndrome. However, its prognostic value in ventilated patients without these conditions is unknown. Objective: to determine the association of mechanical power with the incidence of mortality in patients with invasive artificial ventilation in the Intensive Care Unit. Methods: a prospective cohort study in 52 patients ventilated invasively in an Intensive Care Unit of a Cuban hospital. The final variable of interest was mortality. Sociodemographic and ventilatory variables were studied. The level of significance was found according to p value ≤ 0.05 through hypothesis testing of differences in means and proportions and the the area under the ROC curve. Results: mortality predominated in female patients, with a mean age of 51.76 ± 21.76 years. The main causes of ventilation were respiratory. High APACHE II score, SOFA and a mean mechanical power value of 14.82 ± 1.67 J/min were associated with mortality. On analysis of the area under the ROC curve, mechanical power yielded adequate discriminative ability for mortality (AROC: 0.993; 95 % CI: 0.979 - 1; p = 0.000). Conclusions: In this series of ventilated patients the mechanical power value proved to be a factor associated with mortality.
