ANÁLISE DE DESEMPENHO DO SISTEMA FOTOVOLTAICO CONECTADO À REDE DO IFAM CAMPUS MANAUS CENTRO EM SEU PRIMEIRO ANO DE OPERAÇÃO

This article addresses the performance analysis and monitoring of a photovoltaic system connected to the grid through the calculation of merit indices and the projection of energy generation. The study was applied to the photovoltaic system, more than a year in operation, of the Federal Institute of Education Science and Technology of Amazonas (IFAM) Campus Manaus Centro. The objective was to calculate the Productivity, the Performance Ratio, and the Capacity Factor from the real data of the system's generation and the solar irradiation data provided by the National Institute for Space Research (INPE). Although preceded by forecasts and projects, installations of photovoltaic systems are subject to loss of performance for various reasons. Energy losses can occur due to errors inherent to the transposition model, classification of modules, dust, dirt, and others, and may exceed 8.7% in the first year. Such losses directly affect the energy generated, and performance monitoring is essential. In the present analysis, the real data of energy generation of the first twelve months of operation were collected and, by a computationally implemented model, the energy generation of the system under study was simulated. The average irradiation data for the period were gathered and converted to the photovoltaic modules plan, enabling the calculation of merit indices. It was observed, for an average irradiation of 4.28 kWh/m². day, in the plan of the modules for the first year of operation, the productivity (Y) of 1,254.34 kWh/kWp with a performance ratio (PR) of 80, 29% and capacity factor of 14.32%. The results of energy generated in the real system and the energy predicted by computer simulation showed significant disparities in specific months. We suggest, in future approaches, the generation of the I-V curve to verify possible anomalies or malfunctions in specific modules associated with the installation's panels.
Interannual land cover and vegetation variability based on remote sensing data in the HTESSEL land surface model: implementation and effects on simulated water dynamics

Abstract. Vegetation largely controls land surface–atmosphere interactions. Although vegetation is highly dynamic across spatial and temporal scales, most land surface models currently used for reanalyses and near-term climate predictions do not adequately represent these dynamics. This causes deficiencies in the variability of modeled water and energy states and fluxes from the land surface. In this study we evaluated the effects of integrating spatially and temporally varying land cover and vegetation characteristics derived from satellite observations on modeled evaporation and soil moisture in the Hydrology Tiled ECMWF Scheme for Surface Exchanges over Land (HTESSEL) land surface model. Specifically, we integrated interannually varying land cover from the European Space Agency Climate Change Initiative and interannually varying leaf area index (LAI) from the Copernicus Global Land Services (CGLS). Additionally, satellite data on the fraction of green vegetation cover (FCover) from CGLS were used to formulate and integrate a spatially and temporally varying effective vegetation cover parameterization. The effects of these three implementations on model evaporation fluxes and soil moisture were analyzed using historical offline (land-only) model experiments at the global scale, and model performances were quantified with global observational products of evaporation (E) and near-surface soil moisture (SMs). The interannually varying land cover consistently altered the evaporation and soil moisture in regions with major land cover changes. The interannually varying LAI considerably improved the correlation of SMs and E with respect to the reference data, with the largest improvements in semiarid regions with predominantly low vegetation during the dry season. These improvements are related to the activation of soil moisture–evaporation feedbacks during vegetation-water-stressed periods with interannually varying LAI in combination with interannually varying effective vegetation cover, defined as an exponential function of LAI. The further improved effective vegetation cover parameterization consistently reduced the errors of model effective vegetation cover, and it regionally improved SMs and E. Overall, our study demonstrated that the enhanced vegetation variability consistently improved the near-surface soil moisture and evaporation variability, but the availability of reliable global observational data remains a limitation for complete understanding of the model response. To further explain the improvements found, we developed an interpretation framework for how the model development activates feedbacks between soil moisture, vegetation, and evaporation during vegetation water stress periods.
Experimental assessment of methods of dissemination of the thermodynamic temperature at the highest temperatures

In the frame of the European Metrology Research Programme (EMRP)-funded joint research project “Implementing the new kelvin” one work package is devoted to the assessment of two different methods of dissemination of the thermodynamic temperature. These two methods are the dissemination via high temperature fixed points (HTFP) with assigned thermodynamic temperatures and the dissemination by radiometers or radiation thermometers calibrated in terms of thermodynamic temperature. To achieve a thorough assessment of these two distinct dissemination methods two dissemination exercises were organised in the form of comparisons. In one case the circulating artefacts were off-the-shelf high-temperature fixed point cells with transition temperatures ranging from 1324 °C to 2474 °C, in the other case absolutely calibrated pyrometers and filter radiometers were compared in the temperature range 1000 °C to 2500 °C. This work showed that both schemes were achievable with competing advantages and drawbacks and would most probably help disseminating thermodynamic temperature in the future at the level of 1 K to 2 K uncertainty over the whole temperature range.
Evaluating Enterococcus faecium 9 N‐2 as a probiotic candidate from traditional village white cheese

Abstract In this study, various functional and probiotic attributes of the Enterococcus faecium 9 N‐2 strain isolated from village‐style white cheese were characterized, while also assessing its safety. To achieve this, we conducted an in vitro analysis of several key probiotic properties exhibited by the 9 N‐2 strain. Notably, this strain demonstrated robust resilience to low pH, high bile salt concentrations, lysozyme, pepsin, pancreatin, and phenol. Furthermore, this strain displayed exceptional auto‐aggregation capabilities and moderate co‐aggregation tendencies when interacting with Escherichia coli. The cell‐free supernatant derived from strain 9 N‐2 exhibited significant antimicrobial activity against the tested pathogens. The strain exhibited resistance to gentamicin, meropenem, and bacitracin, while remaining susceptible to vancomycin and various other antibiotics. Furthermore, it was found that E. faecium 9 N‐2 possessed the capacity to produce the phytase enzyme. When all the results of this study are evaluated, it is thought that 9 N‐2 strain has superior probiotic properties, and therefore it can be used as probiotic in food, medicine, and animal feed in the future. In addition, further in vivo tests should be performed to fully understand its effects and mechanisms of action and to confirm its safety and probiotic effects. Further research and clinical trials are also needed to identify new strains with potential probiotic properties.
El concepto de "pulso de inundación" en relación a las planicies aluviales del sistema fluvial Paraná-Paraguay

The present study deais with the floodplains occurring in the Paraná-Paraguay fluvial system, with special emphasis on their degree o f fitness to the “flood-pulse” concept proposed by Junk et al. (1989). “Fringe” floodplains o f different stretches of the Paraná river and o f the lower reach o f the Paraguay were found to keep many similarities. Instead. both the Upper Paraguay’s Pantanal and the Paraná’s Delta pose problems that require specific studies in order to interpret correctly, and eventuallyadjust, the “pulse” concept, as well as to better assess its effects on the river’s productivity.
Stereo-vision based 3D modeling for unmanned ground vehicles

Instant Scene Modeler (iSM) is a vision system for generating calibrated photo-realistic 3D models of unknown environments quickly using stereo image sequences. Equipped with iSM, Unmanned Ground Vehicles (UGVs) can capture stereo images and create 3D models to be sent back to the base station, while they explore unknown environments. Rapid access to 3D models will increase the operator situational awareness and allow better mission planning and execution, as the models can be visualized from different views and used for relative measurements. Current military operations of UGVs in urban warfare threats involve the operator hand-sketching the environment from live video feed. iSM eliminates the need for an additional operator as the 3D model is generated automatically. The photo-realism of the models enhances the situational awareness of the mission and the models can also be used for change detection. iSM has been tested on our autonomous vehicle to create photo-realistic 3D models while the rover traverses in unknown environments. Moreover, a proof-of-concept iSM payload has been mounted on an iRobot PackBot with Wayfarer technology, which is equipped with autonomous urban reconnaissance capabilities. The Wayfarer PackBot UGV uses wheel odometry for localization and builds 2D occupancy grid maps from a laser sensor. While the UGV is following walls and avoiding obstacles, iSM captures and processes images to create photo-realistic 3D models. Experimental results show that iSM can complement Wayfarer PackBot's autonomous navigation in two ways. The photo-realistic 3D models provide better situational awareness than 2D grid maps. Moreover, iSM also recovers the camera motion, also known as the visual odometry. As wheel odometry error grows over time, this can help improve the wheel odometry for better localization.
View from the fringe - transdiciplinarity and the journey of the devox

The problems of today are complex and context dependant. Solutions need to be developed taking into account the individual issues that relate to each problem. There is no one size fits all solution. The complexity usually requires that the knowledge and skills of a range of disciplines are required to develop a suitable solution. The need for transdisciplinarity becomes apparent in this space. This paper gives an introduction to transdisciplinarity and its relationship to Mode 1 and Mode 2 knowledge. The three pillars of transdisciplinarity are discussed and their link to the problem space if demonstrated in the case study of safe design. The case study tracks how deviance theory can be demonstrated in the journey of the devox - the innovation virus.
Public awareness of blood donation in central saudi arabia

significant predictors of blood donation, with the significance set at P , 0.05. Results: Approximately half of all subjects (53.3%) reported that they had previously donated blood, 39% of whom had donated more than once. The knowledge percentage mean score was 58.07%, denoting a poor level of knowledge, with only 11.9% reporting a good level of knowledge. The attitude percentage mean score towards donation was 75.45%, reflecting a neutral attitude towards donating blood, with 31.6% reporting a positive attitude. Donation was significantly more prevalent among males than females (66% versus 13.3%; P , 0.001). After adjustment for confounders, a higher knowledge score ( t = 2.59; P = 0.01), a higher attitude score ( t = 3.26; P = 0.001), and male sex ( t = 10.45; P , 0.001) were significant predictors of blood donation. An inability to reach the blood donation centers and a fear of anemia were the main reasons for females not donating blood (49.9% and 35.7%, respectively), whereas a lack of time was the main reason for males (59.5%). Conclusion: Prevalence of blood donation was less than satisfactory among the Saudi public, probably due to misconceptions, poor knowledge, and unfavorable attitude to donation. Educational programs are necessary to increase the level of knowledge and improve the attitude of the Saudi public toward blood donation. Providing mobile blood collection units nearer to individuals’ places of work to reduce their time costs of donating is a necessity.
Validity and Reliability of Teachers' Psychological Well-Being Instruments in School Organizations Based on the Rasch Model Approach: A Pilot Study

This pilot study was to validate and examine the reliability of the psychological well-being instrument in school organizations (i-OS). This instrument consists of 130 items and was distributed to 60 teachers from two schools in the Federal Territory of Kuala Lumpur. This instrument was developed to measure four constructs namely i) job demands of teachers in schools; ii) sources of teacher employment in schools; iii) teacher's personal resources; and iv) holistic psychological well-being of teachers in schools. The Rasch Model approach was used to check the validity and reliability of the instrument through this pilot study. The Rasch model is used because this approach can measure the reliability of respondents and items and it is even stronger than just looking at Cronbach's Alpha. Winsteps Version 4.8. 0.01 software was used to examine the functionality of items from the aspect of reliability and item-respondent isolation; polarity; item fit measures the construct; standardized residual correlation value; scale review; maps of individual abilities and item difficulties; and differences in item functioning (DIF) based on gender. The final analysis found that 27 items were dropped because they did not meet the inspection criteria and 8 items were refined because they partially met the inspection criteria and took into account the expert's recommendations. The final instrument showed a total of 103 items suitable for use after refinement to measure the four constructs of the i-OS instrument. Since this study is only a pilot study, distribution to real respondents can be done to measure all four i-OS constructs.

Over the last two decades coronary artery calcium (CAC) scanning has emerged as a quick, safe, and inexpensive method to detect the presence of coronary atherosclerosis. Data from multiple studies has shown that compared to individuals who do not have any coronary calcifications, those with severe calcifications (i.e., CAC score > 300) have a 10-fold increase in their risk of coronary heart disease events and cardiovascular disease. Conversely, those that have a CAC of 0 have a very low event rate (~0.1%/year), with data that now extends to 15 years in some studies. Thus, the most notable implication of identifying CAC in individuals who do not have known cardiovascular disease is that it allows targeting of more aggressive therapies to those who have the highest risk of having future events. Such identification of risk is especially important for individuals who are not on any therapies for coronary heart disease, or when intensification of treatment is being considered but has an uncertain role. This review will highlight some of the recent data on CAC testing, while focusing on the implications of those findings on patient management. The evolving role of CAC in patients with diabetes will also be highlighted.
Performance Analysis of AODV Routing Protocol In Vehicular Ad-hoc Network Service Discovery Architecture

VANET is the special type of MANET (Mobile Ad Hoc Networks) where the mobile nodes are vehicles that move on roads at very high speed following traffic rules; they provide communication between vehicle and vehicle (V2V) and Vehicle and Road side infrastructural unit (V 2 I). This paper explores the possibility of using VANET in inter vehicular communication. An attempt has been made earlier to create a new cluster model for efficient communication among the VANET nodes by the author [1]. A new clustering model has been created after taking the Simple Highway Vehicular model concept into consideration. This paper focuses the development of a clustering framework for data communication among the VANET nodes and the service discovery in Highway VANET model where the vehicles are moving outside the city. In the earlier study, the author of the paper [3] discussed the service discovery inside the city where more number of road side units are available and the communication between vehicle and vehicle (V2V) is established using road side unit only. But this paper discusses a service discovery architecture and data communication for vehicles outside the city where there is no road side unit (RSUs).
JWST Census for the Mass–Metallicity Star Formation Relations at z = 4–10 with Self-consistent Flux Calibration and Proper Metallicity Calibrators

We present the evolution of the mass–metallicity (MZ) relation at z = 4–10 derived with 135 galaxies identified in JWST/NIRSpec data taken from the three major public spectroscopy programs of ERO, GLASS, and CEERS. Because there are many discrepancies between the flux measurements reported by the early ERO studies, we first establish our NIRSpec data reduction procedure for reliable emission-line flux measurements and errors, successfully explaining Balmer decrements with no statistical tensions thorough comparisons with the early ERO studies. Applying the reduction procedure to the 135 galaxies, we obtain emission-line fluxes for physical property measurements. We confirm that 10 out of the 135 galaxies with [O iii] λ4363 lines have electron temperatures of ≃(1.1–2.3) × 104 K, similar to lower-z star-forming galaxies, which can be explained by heating by young massive stars. We derive the metallicities of the 10 galaxies by a direct method and the rest of the galaxies with strong lines using the metallicity calibrations of Nakajima et al. applicable for these low-mass metal-poor galaxies, anchoring the metallicities with the direct-method measurements. We thus obtain the MZ relation and star formation rate (SFR)–MZ relation over z = 4–10. We find that there is a small evolution of the MZ relation from z ∼ 2–3 to z = 4–10, while interestingly the SFR–MZ relation shows no evolution up to z ∼ 8 but a significant decrease at z > 8 beyond the errors This SFR–MZ relation decrease at z > 8 may suggest a break of the metallicity equilibrium state via star formation, inflow, and outflow, while further statistical and local-baseline studies are needed for a conclusion.
Recent advances in the development of flexible dye-sensitized solar cells: fabrication, challenges and applications-a review

Flexible dye-sensitized solar cells (FDSSCs) show a huge potential for stretchable electronics and portable power sources due to their lightweight, handy, flexibility, cost-effective, and easy processing. This paper introduces basic operating principles and design opportunities for maximum efficiencies for FDSSCs. Flexible polymers or metal substrates, enabling cost reduction due to large volume production with roll to roll manufacturing technique. DSSCs achieved a power conversion efficiency (PCE) of 14.30% on rigid conductive substrates, 10.28% on flexible metal substrates, and 8% on plastic substrates. A brief distinction has been made on different substrates, preparation of charge transfers materials, coating and printing techniques and processing methods for enhancing the performance of FDSSCs. We also highlight issues pertaining to progress in the stability of devices and the commercialisation of FDSCs technologies will be explained.
Economic plant diversity and distribution: application of spatial analysis for the conservation of germplasm diversity in Latin America

Ecogeographic studies provide critical information on plant genetic resources (PGR) to assess their current conservation status and prioritize areas for conservation. They have also proven to be useful for planning for effective genebank management, such as the definition of core collections and identification of collection gaps. In this update, we give an overview of relevant techniques and advances in ecogeographic studies of PGR that can be used to analyse biodiversity data based on field-collected data and to target further collecting. We commence with providing some general recommendations that are important when setting up new research projects that are aimed at assessing the conservation status of PGR and/or monitoring trends in (agricultural) biodiversity on the basis of ecogeographic analysis. A brief introduction to commonly used methods and techniques for the analysis of interand intra-specific diversity is provided. The latter include multivariate methods such as clustering and ordination. We also elaborate on mapping of (agricultural) biodiversity data and emphasize the importance of ensuring good data quality. Furthermore, we provide a synopsis of methods for distribution modelling and present an overview of useful open-access and commercial statistical and GIS packages. i Adapted from: van Zonneveld M, Thomas E, Galluzzi G, Scheldeman X (2011) Chapter 15/16: Mapping the ecogeographic distribution of biodiversity and GIS tools for plant germplasm collectors.

Elevated expression of TUBA1C in breast cancer predicts poor prognosis

α1C-tubulin (TUBA1C) is a member of the α-tubulin family and has served as a potential biomarker in a variety of cancers in many studies. In this study, the gene expression profile of TUBA1C in The Cancer Genome Atlas (TCGA) was extracted for analysis, and the prognostic value of TUBA1C in breast cancer was comprehensively evaluated. The Wilcoxon signed-rank test, Kruskal-Wallis test, and logistic regression analysis were performed to confirm the correlations between TUBA1C expression and the clinical characteristics of breast cancer patients. The effect of TUBA1C expression on the survival of breast cancer patients was assessed by Kaplan-Meier curve, Cox regression analysis, and the Kaplan-Meier plotter (an online database). The TCGA data set was used for the Gene Set Enrichment Analysis (GSEA). The results confirmed that high TUBA1C expression in breast cancer was closely correlated with survival time, survival status, and tumor size. In addition, elevated TUBA1C expression can predict poor overall survival (OS), recurrence-free survival (RFS), and distant metastasis-free survival (DMFS). Univariate and multivariate analyses (Cox regression analyses) confirmed that TUBA1C was an independent prognostic factor for the OS of breast cancer patients. The GSEA identified that the high TUBA1C expression phenotype was differentially enriched in cell cycle, basal transcription factor, P53 signaling pathway, pathways in cancer, TOLL-like receptor signaling pathway, and NOD-like receptor signaling pathway. In summary, high messenger RNA (mRNA) expression of TUBA1C is an independent risk factor for poor prognosis of breast cancer.
