Reliability Overview of Grid-Connected Solar PV System: A Review
Authors: Obatola Samuel O.
Published: June 2024

Photovoltaic generation is the most practical renewable energy alternative since it receives adequate sun irradiation throughout the year. Solar systems are often first modeled using design tools including MATLAB/Simulink to rectify as well as tweak variables to achieve the direct current (DC) as well as voltage requirements with the irradiance as well as ambient high temperature. On simulated systems, reliability tests and analysis are done to determine the performance as well as high durability just before system components fail. This study overviews various systematic methods for evaluating the reliability performance of large-scale grid-connected photovoltaic systems while taking into account variations in power input as well as ambient condition relaying failure rates of critical components such as Photovoltaic module, inverters, switch gears, transformers, and capacitors. The total system dependability also comprises the mean time to failure (MTTF) as well as mean time to repair, MTTR of a power system. An output of photovoltaic electricity fluctuates substantially and is affected by sun temperature and irradiation, giving intermittent as well as variable energy generation. A probabilistic analytical technique is used to analyse an existing model of grid-connected PV systems. The dependability or reliability of a grid connected system is determined by the failure rate, and various PV grid components such as inverters, PV modules, switch gears, transformers, and so on are analyzed using established FMEA and Weibull models. This paper overviews the reliability of solar PV grid-connected systems and identify the factors that affect their performance. The paper provides a review of the current state of research on PV systems, including the components that make up the system, their operation, and the potential failure modes. Additionally, the paper identifies some of the key factors that contribute to the reliability of the solar PV grid-connected system, including environmental factors, design factors, and maintenance strategies.

Elaborar un plan de seguridad en medicina estética. Una necesidad inaplazable
Authors: Ortiz Minuesa Ana
Published: June 2024

El interés por la seguridad del paciente en la atención sanitaria se ha ido incrementando en las dos últimas décadas. Durante el desarrollo de la práctica asistencial ocurren efectos adversos que pueden ser el resultado de recursos inadecuados, de procesos y sistemas poco seguros y/o de errores de los propios profesionales en el momento de la intervención. La elaboración de un plan de seguridad ad hoc disminuirá la aparición de estos. En el ámbito de la medicina estética no hay publicaciones que hagan referencia a la existencia de planes de seguridad en la práctica diaria. En este trabajo se propone la metodología que debe seguirse para la elaboración de un plan de seguridad, basado en la recogida de los eventos adversos más frecuentes, a partir de los cuales se elaborarán las acciones preventivas. Por último, se propone la creación de un registro central de efectos adversos; lo que ayudará a conocerlos mejor, optimizará la calidad asistencial y aumentará la seguridad de los tratamientos a los pacientes.

Authors: Jean Y. Villasin  , Riah Encarnacion
Published: June 2024

Managing real estate properties efficiently presented challenges due to the complexity of tasks involved, including tenant communication, maintenance scheduling, and financial tracking. Traditional methods often relied on manual processes, leading to inefficiencies, errors, and delays. Motivated by the need for a streamlined solution, this paper introduced a web-based real estate property management system designed to address these challenges. By employing a descriptive research design and utilizing the mixed methodology approach, the study investigates the challenges faced by realtors in managing property information. It also evaluated the current information management systems of each realtor in handling property listing, sales, leases, and rentals. The research findings revealed that 45% of respondents encounter challenges in property information management, primarily related to inefficient handling of sales information and lease agreements. While 72.7% of respondents use real estate software, shortcomings such as a lack of detailed property information and communication issues underline the need for a comprehensive web-based management system meeting various real estate management needs, as preferred by 90.9% of respondents. The results of the study will be used to propose a web-based real estate property management system for the overall efficiency of real estate operations and revolutionize how real estate assets were managed and optimized in digital age

Steganography is the art and science of writing hidden messages in such a way that no one apart from sender and intended recipient even realizes there is a hidden message. There are often cases when it is not possible to send messages openly or in encrypted form. This is where steganography can come into play. While cryptography provides privacy, steganography is intended to provide secrecy. The aim of steganography is to hide the secret messages and also for communication and transferring of data. Steganography is also used in transferring the information of credit card or debit card to e-commerce for purchasing items. So no one apart from the authorized sender and receiver will be aware of the existence of the secret data. This intends to give an overview of image steganography and its uses and hiding the files (text file, audio file etc) by using LSB and AES algorithm where AES used for password protecting system so that if anyone can find the stego image they will not read the message because data still in the encrypt form and LSB is used for hiding the data.

Computer viruses are one of the major risks that an individual and a community face to the safe living of a household, enterprise, and government. These malicious software programs are developed to work like viruses: they reproduce themselves and spread, thus damaging the system, data loss and the loss of money. This research paper focuses on the various types of dangers that computer viruses pose, such as data corruption, theft of personal information, system disruption, and reputational damage. The hazards of computer viruses are the main thing that people and organizations need to be aware of in order to protect themselves and their systems from these hazards.
Furthermore, computer viruses can also steal sensitive information, such as passwords, credit card numbers, and personal documents. This theft of personal information can result in financial loss and identity theft. Additionally, viruses can cause system damage, leading to system crashes or malfunctions. This can disrupt normal operations and lead to costly repairs or replacements.

Impact of exchange rate on economic growth in Nigeria
Authors: NYECHE, Ezebunwo
Published: June 2024

This study examined the effect of exchange rate dynamics on economic growth in Nigeria from 1985 to 2021. The study utilized secondary data sources from the World Development Indicators (WDI) and the Central Bank of Nigeria (CBN) Statistical Bulletin. It employed real gross domestic product as a measure of economic growth. In addition to the official exchange rate as a proxy for exchange rate dynamics, the study integrated other domestic factors that can affect economic growth, such as trade openness and external reserves. The econometric techniques employed in the study were unit root tests, cointegration, and autoregressive distributed lag (ARDL)/bound techniques. Following the outcome of the bound test, it was reported that a long-run relationship exists between economic growth, exchange rate, trade openness, and external reserves. The long-run ARDL results reveal that the exchange rate had a positive and statistically significant effect on real GDP in Nigeria, with a unit increase in the exchange rate raising the real GDP by 0.3986 units in the long run; trade openness had a positive and not statistically significant impact on real GDP in Nigeria, suggesting that a unit increase in trade openness increases real GDP by 0.0025 units in the long run; and external reserves had a positive and statistically significant impact on real GDP in Nigeria, indicating that a unit increase in external reserves increases real GDP by 0.4007 units in the long run. Based on the results, the study recommends that the government should develop policies that stabilize the exchange rate. This could involve enhancing foreign exchange reserves management, improving the transparency and predictability of foreign exchange interventions, and possibly considering a more flexible exchange rate regime that can adapt to external shocks while maintaining stability. Policies should focus on gradually opening up the economy to international trade through strategic trade agreements that protect key domestic industries while promoting sectors where Nigeria has a competitive advantage. This approach will help mitigate any negative short-term impacts while capitalizing on long-term benefits.
Keywords: Exchange Rate, Trade Openness, External Reserves and Real Gross Domestic Product.

Alternate materials for the capture and quantification of gaseous oxidized mercury in the atmosphere
Authors: Lown Livia , Dunham-Cheatham Sarrah M. , Lyman Seth N. , Gustin Mae S.
Published: June 2024

Abstract. Methodologies for identifying atmospheric oxidized mercury (HgII) compounds, including particulate-bound HgII (HgII(p)) and gaseous oxidized mercury (HgII(g)), by mass spectrometry (MS) are currently under development. This method requires preconcentration of HgII for analysis due to high instrument detection limits relative to ambient HgII concentrations. The objective of this work was to identify and test materials for quantitative capture of HgII from the gas phase, and to suggest potential surfaces onto which HgII can be collected, thermally desorbed, and characterized using MS methods. From the literature, several compounds were identified as potential sorbent materials and tested in the laboratory for uptake of gaseous elemental mercury (Hg0) and HgII(g) (permeated from a HgBr2 salt source). Chitosan, α-Al2O3, and γ-Al2O3 demonstrated HgII(g) capture in ambient air laboratory tests, without sorbing Hg0 under the same conditions. When compared to cation exchange membranes (CEM), chitosan captured a comparable quantity of HgII(g), while ≤ 90 % of loaded HgII(g) was recovered from α-Al2O3, and γ-Al2O3. When deployed in the field, the capture efficiency of chitosan decreased compared to CEM, indicating environmental conditions impacted the sorption efficiency of this material. The poor recovery of HgII from the tested materials compared to CEM in the field indicate that further identification and exploration of alternative sorbent materials is required to advance atmospheric mercury chemistry analysis by MS methods.
Comparing space-based to reported carbon monoxide emission estimates for Europe’s iron & steel plants
Authors: Leguijt Gijs , Maasakkers Joannes D. , Denier van der Gon Hugo A. C. , Segers Arjo J. , Borsdorff Tobias , van der Velde Ivar R. , Aben Ilse
Published: June 2024

Abstract. We use satellite observations of carbon monoxide (CO) to estimate CO emissions from European integrated iron & steel plants, the continent’s highest emitting CO point sources. We perform analytical inversions to estimate emissions from 21 individual plants using observations from the Tropospheric Monitoring Instrument (TROPOMI) for 2019. As prior emissions, we use values reported by the facilities to the European Pollutant Release and Transfer Register (E-PRTR). These reported emissions vary in estimation methodology, including both measurements and calculations. With the Weather Research and Forecasting (WRF) model, we perform an ensemble of simulations with different transport settings to best replicate the observed emission plumes for each day and site. Comparing the inversion-based emission estimates to the E-PRTR reports, nine of the plants agree within uncertainties. For the remaining plants, we generally find lower emission rates than reported. Our posterior emission estimates are well-constrained by the satellite observations (90 % of the plants have averaging kernel sensitivities above 0.7) except for a few low-emitting or coastal sites. We find agreement between our inversion results and emissions we estimate using the Cross-Sectional Flux (CSF) method for the seven strongest-emitting plants, building further confidence in the inversion estimates. Finally, for four plants with large year-to-year variability in reported emission rates or large differences between the reported emission rate and our posterior estimate, we extend our analysis to 2020. We find no evidence in either the observed carbon monoxide concentrations or our inversion results for strong changes in emission rates. This demonstrates how satellites can be used to identify potential uncertainties in reported emissions.
Review and syntheses: Ocean alkalinity enhancement and carbon dioxide removal through coastal enhanced silicate weathering with olivine
Authors: Geerts Luna J. J. , Hylén Astrid , Meysman Filip J. R.
Published: June 2024

Abstract. Coastal enhanced silicate weathering (CESW) is increasingly receiving attention as a marine-based carbon dioxide removal (CDR) technology. The method aims to achieve ocean alkalinity enhancement (OAE) by introducing fast-weathering silicate minerals into coastal systems. The latter is envisioned to act as a large natural biogeochemical reactor, where ambient physical and biological processes can stimulate silicate dissolution, thus generating a concomitant alkalinity release and increasing the seawater’s capacity to sequester CO2. Olivine has been forwarded as the prime candidate mineral for CESW, but to the present, no results from larger-scale field studies in actual coastal systems are available, so all information is exclusively derived from idealized laboratory experiments. As a result, key uncertainties remain concerning the efficiency, CO2 sequestration potential, and impact of olivine-based CESW under relevant field conditions. In this review, we summarize recent research advancements to bridge the gap between existing laboratory results and the real-world environment in which CESW is intended to take place. To this end, we identify the key parameters that govern the dissolution kinetics of olivine in coastal sediments, and the associated CO2 sequestration potential, which enable us to identify a number of uncertainties that are outstanding with respect to the implementation and upscaling of olivine-based CESW, as well as the monitoring, reporting, and verification (MRV). From our analysis, we conclude that the current knowledge base is not sufficient to predict the outcome of in situ CESW applications. Particularly, the impact of pore water saturation on the olivine dissolution rate and the question of the additionality of alkalinity generation remain critical unknowns. To more confidently assess the potential and impact of olivine-based CESW, dedicated pilot studies under filed conditions are needed, which should be conducted at a sufficiently large spatial scale and monitored for a long enough time with sufficient temporal resolution. Additionally, our analysis indicates that the specific sediment type of the application site (e.g. cohesive versus permeable) will be a critical factor for olivine-based CESW applications, as it will significantly impact the dissolution rate by influencing the ambient pore water pH, saturation dynamics, and natural alkalinity generation. Therefore, future field studies should also target different coastal sediment types.
La amenaza silenciosa de las resistencias bacterianas

Published: June 2024

Las resistencias bacterianas a antimicrobianos representan uno de los principales problemas en la actualidad, encontrándose dentro de las principales causas de muerte en todo el mundo. Latinoamérica y Argentina, lejos de ser una excepción a dichos números, presentan año tras año mayor incidencia de infecciones por gérmenes resistentes. Cada día, se conocen con mejor y mayor detalle los mecanismos de resistencia que presentan tanto los Bacilos Gram Negativos como algunos Cocos Positivos. Sin embargo, limitar el problema al sobreuso de antimicrobianos en medicina clínica es solo una pequeña parte de este fenómeno. Así la sobreutilización de los mismos para maximizar los beneficios en pesca, ganadería y cultivo, se han transformado en los principales pilares que sostienen esta problemática. Desde la Atención Primaria de la Salud, consideramos fundamental conocer todos los aspectos que forman parte de esto, para intentar mitigar el daño que las resistencias bacterianas generan en el mundo. Argentina se transformó en el primer país de la región del continente en contar con una Ley de Prevención y Control de la Resistencia a los Antimicrobianos. Sostenemos que es de marcada importancia, que se fomenten más y mejores políticas sanitarias de orden público para poder así enfrentar este creciente desafío.

Pada dunia pendidikan khususnya elektronika memerlukan alat penunjang praktik seperti alat praktik rangkaian digital salah satunya ialah trainer. Dasar dari pembentukan sistem digital trainer adalah gerbang logika. Rangkaian digital terdiri dari sekelompok gerbang logika, yang beroperasi dalam bilangan biner. Untuk membuat trainer ini di butuhkan gerbang logika. Gerbang logika yang dipergunakan untuk membuat trainer adder dan subtractor yaitu: Inverting Gate, AND Gate, OR Gate, dan Exclusive-OR Gate. Untuk menjalankan trainer adder dan subtractor ini dibutuhkan tegangan 220 VAC dan menghasilkan output sebesar 5 VDC . Saat switch menghasilkan on, maka output bernilai 1 dan off menghasilkan output bernilai 0. LED berfungsi sebagai tampilan output dari rangkaian trainer. Pada trainer adder ini berfungsi untuk melakukan pertambahan suatu bilangan biner, yang terdiri dari 2 macam yaitu half adder dan full adder. Half adder berfungsi untuk pengoperasian pertambahan bilangan biner dengan 1 bit, kemudian untuk full adder berfungsi untuk melakukan pengoperasian pertambahan bilangan biner penuh lebih dari 1 bit. Sedangkan trainer subtractor berfungsi untuk melakukan pengurangan yang terdiri dari half subtractor untuk rangkaian operasi pengurangan sebagian pada data-data bilangan biner 1 bit. Full Subtractor untuk pengurangan penuh dengan bilangan biner lebih dari 1.

Hasil belajar IPA siswa kelas V SD di kecamatan Gegesik tergolong rendah. Rendahnya hasil belajar IPA ini disebabkan oleh pembelajaran yang bersifat teacher centered dan guru hanya menggunakan metode ceramah dalam pembelajaran. Siswa pun merasa bahwa IPA adalah mata pelajaran yang sulit, karena selain berhitung siswa juga harus menghafal. Berdasarkan hasil pendahuluan tersebut, peneliti merancang pembelajaran dengan model SAVI (Somatis, Auditori, Visual dan Intelektual) pada pokok bahasan alat pernapasan pada manusia. Penelitian ini bertujuan untuk mengetahui pengaruh model SAVI (Somatis, Auditori, Visual dan Intelektual) pada pokok bahasan alat pernapasan pada manusia terhadap hasil belajar mata pelajaran IPA kelas V SD Negeri 1 Bayalangu Kidul. Penelitian ini menggunakan desain True Eksperimental Design dengan bentuk desain penelitiannya Pretest-Posttest Control Group Design. Teknik sampling yang digunakan yaitu teknik Sampling Jenuh. Sampel penelitian yang berjumlah 40 siswa, dibagi rata menjadi dua kelompok secara random (acak). Instrumen yang digunakan adalah soal tes bentuk pilihan ganda berjumlah 20 soal. Setelah dilakukan perlakuan yang berbeda, diperoleh nilai rata-rata posttest kelompok eksperimen 77,75 dan kelompok kontrol 58,25. Berdasarkan hasil uji hipotesis statistik dengan menggunakan uji N-Gain diperoleh rata-rata pre-test dan posttest sebesar 63,32% dan kelompok kontrol 29,23%. Selain itu berdasarkan uji T memperoleh bahwa nilai= 7,014 > ttabel= 2,024 makaditerima. Artinya terdapat pengaruh model pembelajaran SAVI (Somatis, Auditori, Visual, dan Intelektual) terhadap hasil belajar IPA siswa kelas V SD Negeri 1 Bayalangu pada materi alat pernapasan pada manusia.
