Authors: Rovetto Ermes Ivan , Luz Carlos , La Spada Federico , Meca Giuseppe , Riolo Mario , Cacciola Santa Olga
Published: June 2023

This study identified secondary metabolites produced by Alternaria alternata, Colletotrichum gloeosporioides, and Penicillium digitatum in fruits of two blood orange cultivars before harvest. Analysis was performed by UHPLC–Q-TOF-MS. Three types of fruits were selected, asymptomatic, symptomatic showing necrotic lesions caused by hail, and mummified. Extracts from peel and juice were analyzed separately. Penicillium digitatum was the prevalent species recovered from mummified and hail-injured fruits. Among 47 secondary metabolites identified, 16, 18, and 13 were of A. alternata, C. gloeosporioides, and P. digitatum, respectively. Consistently with isolations, indicating the presence of these fungi also in asymptomatic fruits, the metabolic profiles of the peel of hail-injured and asymptomatic fruits did not differ substantially. Major differences were found in the profiles of juice from hail-injured and mummified fruits, such as a significant higher presence of 5,4-dihydroxy-3,7,8-trimethoxy-6C-methylflavone and Atrovenetin, particularly in the juice of mummified fruits of the Tarocco Lempso cultivar. Moreover, the mycotoxins patulin and Rubratoxin B were detected exclusively in mummified fruits. Patulin was detected in both the juice and peel, with a higher relative abundance in the juice, while Rubratoxin B was detected only in the juice. These findings provide basic information for evaluating and preventing the risk of contamination by mycotoxins in the citrus fresh fruit supply chain and juice industry.

Authors: Pórfy Barnabás
Published: June 2023

Measuring quantum-statistical, femtoscopic (including final state interactions) momentum correlations with final state interactions in high-energy nucleus-nucleus collisions reveal the space-time structure of the particle-emitting source created. In this paper, we report NA61/SHINE measurements of femtoscopic correlations of identified pion pairs and describe said correlations based on symmetric Lévy-type sources in Ar+Sc collisions at 150A GeV/c. We investigate the transverse mass dependence of the Lévy-type source parameters and discuss their possible interpretations.

Weather forecasting is an essential task in any region of the world for proper planning of various sectors that are affected by climate change. In Warangal, most sectors, such as agriculture and electricity, are mainly influenced by climate conditions. In this study, weather (WX) in the Warangal region was forecast in terms of temperature and humidity. A radial basis function neural network was used in this study to forecast humidity and temperature. Humidity and temperature data were collected for the period of January 2021 to December 2021. Based on the simulation results, it is observed that the radial basis function neural network model performs better than other machine learning models when forecasting temperature and humidity.

Authors: Loi Alicia Siew Ting , Sridhar Revathi , Lim See Ming
Published: June 2023

Healthcare workers are recommended to get vaccinated against measles and varicella. This study aims to describe the implementation process of a measles and varicella vaccination program and report on the reduction in the number of susceptible healthcare workers exposed to measles, varicella, and disseminated herpes zoster at a tertiary hospital. The Consolidated Framework for Implementation Research (CFIR) model was used to describe the vaccination program implemented from October 2015 to September 2018. The number of exposed, reviewed, and susceptible healthcare workers during contact tracing for exposure to (a) measles and (b) varicella and disseminated herpes zoster in 2016, 2017, and 2018 is reported. A total of 6770 (95%) out of 7083 healthcare workers completed their immunization review by 2018. In 2016, 20 (10%) out of 198 healthcare workers exposed to measles were considered susceptible. In 2018, no one was found susceptible out of the 51 staff members exposed to measles (p < 0.01). For exposure to varicella and disseminated herpes zoster, seven (5%) out of 154 exposed healthcare workers were susceptible in 2016. In comparison, only two (1%) out of 377 exposed healthcare workers in 2018 were susceptible (p < 0.01). The vaccination program effectively reduced number of healthcare workers susceptible to measles, varicella, and disseminated zoster.

The COVID-19 pandemic changed our world as we know it and continues to be a global problem three years since the pandemic began. Several vaccines were produced, but there was a considerable amount of societal turmoil surrounding them that has affected the way people view not only COVID-19 vaccines but all vaccines. We used a survey to compare how attitudes towards vaccination have changed in college students during the pandemic. An initial survey was administered in 2021, then a follow-up in 2022. Out of 316 respondents who answered the first survey, 192 completed the follow-up. The survey was designed to measure trends in changes to vaccine attitudes since the COVID-19 pandemic began. By comparing the first survey in 2021 and the follow-up, we found that roughly 55% of respondents’ vaccine attitudes did not change, roughly 44% of respondents’ attitudes towards vaccines became more positive, and only about 1% of the respondents’ vaccine attitudes became more negative. Improved view of vaccines was associated with political views and increased trust in medicine and the healthcare system. Worsened opinions of vaccines were associated with a belief that the COVID-19 vaccine affected fertility.
Numerical Study on Deposition Behavior of Micron-Sized Suspended Solids in Broken Rock Mass within a Goaf Based on Coupled CFD-DEM Method
Authors: Wang Yunqing , Wang Dangliang , Gao Chengyue , Xiong Shijie
Published: June 2023

After coal mine wastewater is artificially injected into a groundwater reservoir transformed from a goaf, micron-sized suspended matter in the wastewater is purified by the broken rock mass in the goaf. Existing studies can only analyze the macroscopic changes in the content of suspended solids during the purification process, and it is difficult to explain the microscopic deposition mechanism of the suspended solids in broken rock. This paper studied the microscopic deposition behavior of micron-sized suspended solids inside the broken rock mass via numerical simulation using a coupled CFD-DEM method. In addition, indoor model tests were carried out to verify the accuracy and reliability of the model in comparison. The study results show that suspended solids’ deposition behavior varies significantly under broken rock masses’ different pore sizes (0.47 mm, 1.14 mm, 3.00 mm, and 5.33 mm). Within the goaf, the adsorption of suspended solids by the broken rock mass plays a dominant role. At the same time, suspended particles are mostly collected in the inlet area, and the difference in the number of deposited particles can reach 74% when comparing the first 50 mm range as well as the 50–100 mm range. The number of deposited particles at a flow rate of 0.02 m/s is 14% more than that at a flow rate of 0.06 m/s. This work offers new ideas for studying the purification mechanism of coal mine wastewater within a goaf.

Published: June 2023

Precipitation in different phases has varying effects on runoff. However, monitoring surface snowfall poses a significant challenge, highlighting the importance of developing a snowfall detection algorithm. The objective of this study is develop a snowfall detection algorithm for the Microwave Temperature Sounder-2 (MWTS-II) and the Microwave Humidity Sounder-2 (MWHS-II) onboard the FY-3D satellite while considering the differentiated atmosphere temperature conditions. The results show that: (1) The brightness temperature (TB) of MWTS Channel 3 is well-suited for pre-classifying atmospheric temperatures, and significant differences in TB distribution exist between the two pre-classification subsets. (2) Among six machine classifiers examined, the random forest classifier exhibits favorable classification performance on both the validation set (accuracy: 0.76, recall: 0.76, F1 score: 0.75) and test set (accuracy: 0.80, recall: 0.44, F1 score: 0.44). (3) The application of the snowfall detection algorithm showcases a reasonable spatial distribution and outperforms the IMERG and ERA5 snowfall data.

Published: June 2023

The Internet of Things (IoT) has become widespread. Widely used worldwide, it already penetrates all spheres of life, and its symbiosis with the environment has become increasingly important and necessary. IoT in life sciences has gained much importance because it minimizes the costs associated with field research, shipments, and transportation of the sensors needed for physical and chemical measurements. This study proposes an IoT water monitoring system in real time that allows the measurement of dissolved oxygen levels in water at several monitoring points in a difficult-to-access location, the Pirapo River, in southern Brazil, responsible for supplying water to large urban centers in the region. The proposed method can be used in urban and rural areas for consumption and quality monitoring or extended to a modern water infrastructure that allows water providers and decision makers to supervise and make optimal decisions in difficult times. The experimental results prove that the system has excellent perspectives and can be used practically for environmental monitoring, providing interested parties with experiences acquired during the system implementation process and timely relevant information for safe decision making.
Local Scour around Side-by-Side Double Piers in Channel Bends under Ice-Covered Conditions—An Experimental Study
Authors: Song Feihu , Wang Jun , Zhang Zhenhua , Cheng Tiejie , Li Guowei , Sui Jueyi
Published: June 2023

The pier scour process is normally intensified in the presence of an ice cover, which poses risks to the longevity and safety of bridges. In the present study, the impact of the densimetric Froude number, locations, and pier spacing of side-by-side piers on the local scour depth under ice-covered flow conditions were investigated based on clear water scour experiments in an S-shaped laboratory flume. The results demonstrated that the local scour at piers along the convex bank was more substantial than that along the concave bank when other factors stayed identical. The densimetric Froude number clearly has more impact on local scour at piers along the convex bank than that along the concave bank. Different from the mechanism of the pier scour in a straight channel, the scour depth around a pier along the convex bank in the S-shaped flume increases as the distance between two piers (or pier spacing) increases, while it decreases around the piers along the concave bank. Similar scour patterns were observed when the side-by-side piers were installed at different bend apex cross-sections. The maximum local scour depths at piers along the convex bank measured at different bend apex cross-sections were relatively unchanged when other influencing factors were held constant. However, the maximum scour depth around piers along the concave bank decreased as the bends increased toward downstream.

Published: June 2023

Salinity in estuarine environments has been traditionally simulated using process-based models. More recently, data-driven models including artificial neural networks (ANNs) have been developed for simulating salinity. Compared to process-based models, ANNs yield faster salinity simulations with comparable accuracy. However, ANNs are often purely data-driven and not constrained by physical laws, making it difficult to interpret the causality between input and output data. Physics-informed neural networks (PINNs) are emerging machine-learning models to integrate the benefits of both process-based models and data-driven ANNs. PINNs can embed the knowledge of physical laws in terms of the partial differential equations (PDE) that govern the dynamics of salinity transport into the training of the neural networks. This study explores the application of PINNs in salinity modeling by incorporating the one-dimensional advection–dispersion salinity transport equation into the neural networks. Two PINN models are explored in this study, namely PINNs and FoNets. PINNs are multilayer perceptrons (MLPs) that incorporate the advection–dispersion equation, while FoNets are an extension of PINNs with an additional encoding layer. The exploration is exemplified at four study locations in the Sacramento–San Joaquin Delta of California: Pittsburg, Chipps Island, Port Chicago, and Martinez. Both PINN models and benchmark ANNs are trained and tested using simulated daily salinity from 1991 to 2015 at study locations. Results indicate that PINNs and FoNets outperform the benchmark ANNs in simulating salinity at the study locations. Specifically, PINNs and FoNets have lower absolute biases and higher correlation coefficients and Nash–Sutcliffe efficiency values than ANNs. In addition, PINN models overcome some limitations of purely data-driven ANNs (e.g., neuron saturation) and generate more realistic salinity simulations. Overall, this study demonstrates the potential of PINNs to supplement existing process-based and ANN models in providing accurate and timely salinity estimation.
El adulterio como causal de divorcio en parejas con género diverso en la Legislación Ecuatoriana
Authors: Pulla Elizalde Hillary Analy , Sánchez Zambrano José Santiago
Published: June 2023

La causal de adulterio, consta como una de las principales causales de divorcio en el vigente Código Civil de Ecuador. Por ello el objetivo del estudio fue caracterizar el adulterio como causal de divorcio en parejas con género diverso en la Legislación Ecuatoriana. Para ello, se realizó un estudio bajo el enfoque descriptivo, pues al fundamentarse en jurisprudencia, doctrina y ley, se analizó la figura del adulterio establecida en el Artículo 110 numeral 1 “Causal de divorcio por adulterio” del Código Civil. Como resultado se establece que, para poder configurar el adulterio como causal de divorcio, es necesario que se demuestre la existencia de la relación sexual extramatrimonial de manera fehaciente. Se concluye que para que las parejas con género diverso obtengan acceso a la causal de divorcio por adulterio, es necesario añadir que el adulterio también se concrete con “otras prácticas sexuales” y no únicamente por “acceso carnal”.
On International Comparison of National Income Within the CMEA Framework
Authors: Ivanov Yu. N.
Published: June 2023

The article considers the results and methods of international comparisons of national income carried out in the CMEA from 1959 to1988. It is noted that the results of these comparisons were used for solving problems related to the organization of economic cooperation within the CMEA. This goal was consistent with the methodology of bilateral comparisons of the national income of the USSR with each other CMEA countries. The ﬁnal results for each bilateral comparison were computed using the Fisher index formula. This procedure did not secure the transitivity of the results. Considerable attention was paid to selecting commodity representatives with prices for calculating purchasing power parities (PPPs). For this purpose, meetings of experts, who were well-versed in the technical characteristics of the selected commodity representatives, were convened: in some cases, commodity prices were adjusted to ensure their comparability. The biggest challenges emerged while securing price comparability for the following commodity representatives: machinery, equipment, and construction projects.

The paper presents characteristics of GDP based on PPP comparison methodology carried out within the UN ICP framework. It ensured the comparison of UN ICP and the CMEA comparison methods. In particular, it is noted that GDP comparisons were carried out using multilateral methods of comparison, securing the transitivity of the computed indices. In addition to national income indicators of industrial and agricultural output, capital investments and consumption of the population were compared. The article contains two tables with results of comparisons of national income of the CMEA countries, which were initially classiﬁed.

Authors: Frenkel A. A. , Tikhomirov B. I. , Surkov A. A.
Published: June 2023

The article discusses the results of the socio-economic development of Russia in 2022 and highlights trends and forecasts of the dy namics of macroeconomic indicators for 2023–2024. At the same time, the main challenges and threats are analyzed, including production, trade, economic, financial, monetary, infrastructural, logistical and other restrictions that have become the main instruments of the West’s sanctions wars against Russia in the new geopolitical reality associated with Russia’s conducting a special military operation  (SMO).

The main objects of analysis are the current state, trends, risks and threats to the Russian economy, the dynamics of industrial production, prices, inﬂation and foreign trade. It is noted that, despite the toughening of challenges, sanctions and threats in 2022, the macroeconomic results of 2022 turned out to be higher than oﬃcial forecasts and experts' expectations. This made it possible to substantiate the main conclusion of the study that the Russian economy managed to prevent a collapse and ﬁnd additional opportunities to better unlock the potential of economic growth and social progress in the current three-year period of 2023–2025 and in the long term. According to the authors, the need to further transform and improvethe eﬃciency of the Russian economy is predetermined not only by current but also, possibly, future challenges.
Provision of Housing for Residents of the Far East: Statistical Analysis
Authors: Schneiderman I. M. , Yarasheva A. V. , Makar S. V.
Published: June 2023

Building on state statistics, the authors analyzed the situation with providing housing opportunities for residents of the Far Eastern Federal District (FEFD). The objective of the study is to deﬁne the housing stock characteristics of the macroregion. Based on the methods of statistical analysis applied by the authors, the following parameters of the FEFD housing stock are identiﬁed: diﬀerentiation of regions – constituent entities of the Russian Federation in terms of housing provision and housing improvement, the degree of housing satisfaction according toresident surveys, debt on housing loans and aﬀordability of rental housing. The paper demonstrates diﬀerences in the positions of FEFD regions. The article concludes that additional funding of the FEFD regions through state programs since 2014 has not aﬀected the growth of the FEFD housing stock, which in terms of speciﬁc indicators of housing provision, is below the Russian average (2018–2020). The authors argue that for several FEFD regions, there is a dire need to improve housing quality (this applies particularly to the Republic of Buryatia and the Trans-Baikal Territory).
Using Social Marketing to Engage Extension Audiences: Lessons from an Effort Targeting Woodland Owners
Authors: Rickenbach Mark , Greenberg Jerry , Huffaker Buddy , Knoot Tricia , Koshollek Alana , Nielsen Carol , Núñez Jennifer , Simoni Jen , Swenson Steve
Published: June 2023

Social marketing involves applying traditional commercial marketing techniques to public good outcomes. We share findings from use of this approach in reaching woodland owners to promote sustainable forestry in southwest Wisconsin. We experimentally tested three direct mail campaigns. Each included two offers—a free handbook and a free forester visit, but the campaigns varied in terms of landowner segments and marketing messages. Key results across the campaigns include consistent performance of the offers (handbook 17%–19%, forester visit 3%–5%) but varied effects of segment and message. Our results suggest that social marketing can pay dividends in reaching landowners and, potentially, other Extension clientele, but there is more to learn.
Redefining the Concept of Learning in Cooperative Extension
Authors: Worker Steven , Ouellette Kristy , Maille Alexa
Published: June 2023

For Extension educational programs to meet the educational needs of today's youths, families, and communities, Extension needs to expand "what counts" as learning. The purpose of this article is to define learning in the context of Extension. We summarize key aspects of the educational research literature by comparing two prevailing metaphors for learning: acquisition and participation. On the basis of the two metaphors, we developed a definition of learning, and we discuss the related implications for program and curriculum development, pedagogy, professional development, and assessment of learning.

Published: June 2023

University faculty and Extension educators sought to use school gardens in Burundi, Africa, as a means of reducing food insecurity, teaching positive youth development, and increasing experiential learning for Burundian students. Washington State University personnel used videoconferencing to provide training to Burundian nongovernmental organization (NGO) staff on the Cultivating Learning with School Gardens curriculum. The NGO staff then trained teachers in pilot programs at four Burundian schools, where first harvests occurred in May 2016. An agricultural consultant also helped with the gardens. Suggestions for implementation of this school garden curriculum in other countries are provided.
Maximizing Use of an Extension Beef Cattle Data Set: Part 2—Reproductive Rates
Authors: Ramsay Jennifer , Hanna Lauren , Ringwall Kris
Published: June 2023

Previously, we described CHAPS20Y, a historical data set, and trends in CHAPS20Y calving distributions. In this article, we describe reproductive rates, including total females exposed to bull(s), pregnancy, pregnancy loss, calving, calf death loss, weaning, culling, and replacement percentages. Yearly mean exposed females increased from 1994 through 2013, consistent with a greater replacement percentage versus culling percentage. Yearly mean reproductive percentages varied over time. Factors such as weather, body condition, temperament, nutrition, and health likely contributed to this variation. CHAPS20Y is a tool Extension professionals can use to understand beef reproductive rates and help producers set and achieve their herd management goals.
Using Proprietary Databases to Overcome Data Suppression in Industry Cluster Analysis
Authors: Michaud Gilbert , Jolley Jason
Published: June 2023

Extension agents are frequently tasked with determining industry clusters that exist in a region to support economic development. However, data suppression issues recurrently prohibit a comprehensive understanding of heavily concentrated firms in a region, particularly in rural areas. This article discusses the use of North American Industry Classification System codes within the LexisNexis Academic database as a technique for locating data about specific firms and analyzing regional industry clusters. This approach provides a practical and cost-efficient method for Extension agents and other researchers and practitioners to identify clusters and gather firm information in small geographies throughout the United States.
An Incremental Approach to Improving Evaluation Response Rates for Multiday Events
Authors: Goodling Robert , McGee Winifred , Jones Coleen
Published: June 2023

Online survey systems have improved evaluation costs and efficiencies but tend to result in lower response rates. We developed an incremental approach for online evaluation of multiday events. The incremental approach splits a complete evaluation into smaller sections and provides respondents access to both current and past sections. We selected two annual events (one national and one state-level) at which to evaluate the approach. Overall, evaluation response rates with the incremental approach averaged 45.9%, nearly double the 25.3% response rate that is typical with traditional online evaluations. Use of this incremental approach for online evaluation resulted in improved assessment of the respective events, suggesting its usefulness for future event evaluations.

This article describes the academy and provides information for those who may wish to implement a similar program.
Perception of Current and Ideal Practices Related to Public Value in Extension
Authors: Downey Laura , Peterson Donna , Franz Nancy
Published: June 2023

Extension professionals are increasingly encouraged to engage in practices that can advance the public value movement. It is unclear, however, whether recommended practices related to public value are being adopted. In 2014, 235 Extension professionals at Mississippi State University responded to an organizational capacity survey that included questions on public value practices. Research described here explored discrepancies between current and ideal public value practices among Extension professionals. Paired-samples t-tests revealed statistically significant discrepancies between current and ideal public value practices. The findings can inform efforts by Extension professionals seeking to increase awareness and practices related to public value.
Local Food Systems Course for Extension Educators in North Carolina: Summary of an Innovative Program
Authors: Bloom Dara , Lelekacs Joanna , Dunning Rebecca , Piner Abbey , Brinkmeyer Emma
Published: June 2023

Interest in local foods began in the early 2000s and has grown substantially over the past decade and a half. Although Extension is addressing local food systems in many states, training and materials in this program area are nascent. To address this circumstance, we developed a graduate course on local food systems for Extension educators. Post-course evaluations indicate increased confidence and knowledge related to local food system facilitation, implementation, and evaluation. Students cited site tours and panel presentations as the most effective course aspects and suggested improving the course by adjusting content to account for varying levels of familiarity with local food systems.

Authors: Roka Fritz , Thissen Carlene , Monaghan Paul , Morera Maria , Gonzalez Sebastian , Aguilar Jose
Published: June 2023

This article outlines a four-step model for developing a training program for farm labor supervisors. The model draws on key lessons learned during the development of the University of Florida Institute of Food and Agricultural Sciences Farm Labor Supervisor Training program. The program is designed to educate farm supervisors on farm labor laws and to support compliance with workplace regulations critical for the safety of farmworkers and the economic sustainability of agricultural industries. Attentive to building partnerships, assessing needs, tailoring the curriculum, and conducting evaluations, the model can be applied elsewhere to address the farm labor issues confronted by specialty crop growers in other states.
Immersed: Case studies in art and ecology
Authors:   , Cameron Rebecca (Becky)
Published: June 2023

Climate change and biodiversity loss are cultural as much as scientific events, and art can play a role in exploring and debating the current climate crisis. Observational drawing is used as a way of paying careful attention to what is here and now, to produce multiple responses to my lived experience and interconnectedness with my environment. Drawing forms a key part of my praxis, as I learn through a combination of reflection and action in art and in gardening. In seeking sustainability and an ecological civilization we need to first rewrite old ways of thinking and feeling. This thesis examines and critiques the predominant western conceptualisations of the non-human world. Ideas of nature, landscape and wilderness are considered, and how the duality between humans and the non-human they imply can be part of the colonial project. Current ideological models of ecology and new materialism are examined as to how they seek to dissolve this binary, and for what they might offer to the practices of gardening and art. Acknowledging the agency of the non-human world and the coexistence of humans within a web of relationships can lead to art that is ecological. Māori and other indigenous ways of thought and practice are considered, and are seen have many correlations with this ecological thinking. Two case studies are presented; the Nature of the National Parks, and nature in the suburban garden. I examine how art can reveal and critique these ideas and assist in moving towards a new understanding of the place of people in the world. In creating an exhibition presenting my interaction in the ecology of the garden, the intellectual and political labour of the artworks may provide a cognitive and reflective experience to the gallery audience.
Inventorying tourist resources: Assessment of the tourist potential of Vieira do Minho
Authors: Braga José Luís , Borges Isabel , Brás Sandra , Mota Catarina , Costa Fernando
Published: June 2023

This research aims to give an account of the process of inventorying tourist resources of the municipality of Vieira do Minho, located in the district of Braga, in the northwest of Portugal. Specifically, the natural, gastronomic, folkloric, handicraft resources, as well as events were analysed. The justification underlying this study lies in the absence perceived in the municipality, with regard to a complete and detailed cataloguing of all tourist resources. This entailed the creation of an inventory, where it was possible to make a “radiograph” of the existing tourist resources. Thus, some research questions guide our study: (1) How attractive are the tourist resources in Vieira do Minho? (2) What singularity do these resources present? (3) How can we classify Vieira do Minho’s tourist resources according to their notoriety? The potential of a tourist destination is defined by the importance and characteristics of the tourist resources, so its identification is essential for its development process. Each tourist resource examined in this inventory was evaluated, ensuring the most truthful and authentic assessment possible, so that, in this way, some gaps in terms of conservation and preservation of these resources can be filled. This inventory is a tool to make it possible to design and outline plans to boost tourism in the municipality of Vieira do Minho. The survey of resources was based on bibliographical research and empirical research, embodied in the stocktaking of all possible resources according to the following classification: attractiveness (international, national, regional, local and null), uniqueness (good, average and common), notoriety (high, average and low), as well as the quality of accessibility. The results presented in this work allow both the visitor and the Municipality of Vieira do Minho to enjoy detailed information and knowledge of the various tourist resources available in this destination. The present study, by carrying out an inventory and classification of tourist resources in Vieira do Minho, will contribute to transforming the local tourist heritage into resources and products likely to meet the needs of the market segments that choose Vieira do Minho as a destination for their holidays.

Published: June 2023

Abortus merupakan pengeluaran hasil konsepsi yang terjadi pada

umur kehamilan kurang 20 minggu dan berat janin ≤ 500 gram.

Dampak dari abortus jika tidak mendapatkan penanganan

langsung yang cepat dan tepat akan menambah angka kematian

ibu. Tujuan penelitian diketahuinya faktor-faktor yang

berhubungan dengan kejadian abortus. Penelitian ini

menggunakan metode survey analitik dengan pendekatan survey

cross sectional. Penelitian dilakukan bulan Januari tahun 2021 di

Rumah Sakit Muhammadiyah Palembang Tahun 2021. Populasi

dalam penelitian ini adalah semua ibu hamil yang datang

memeriksakan kehamilannya di Rumah Sakit Muhammadiyah

Palembang pada bulan Januari tahun 2021, yang berjumlah 718

orang. Sampel pada penelitian ini adalah sebagian ibu hamil

dengan usia kehamilan 0-6 bulan yang beresiko abortus yang

datang memeriksakan kehamilannya di Rumah

Sakit

Muhammadiyah Palembang tahun 2021. Teknik pengambilan

sampel pada penelitian ini menggunakan sistematis random

sampling dan di dapatkan sampel 88 responden. Data yang

dikumpulkan dalam penelitian ini adalah data

sekunder

menggunakan ceklis dengan cara melihat dokumen Rekam

Medis family folder ibu hamil yang mengalami kejadian abortus

di RS Muhammadiyah Palembang pada Tahun 2021 yang

kemudian di analisis menggunakan analisis univariat dan

bivariate dengan uji Chi-Square. Hasil analisis Chi-Square

ditemukan hasil ada hubungan paritas (pvalue = 0,040) dan

umur ibu (pvalue = 0,036) dengan kejadian abortus, dan

tidak ada hubungan jarak kehamilan (pvalue = 0, 059)

dengan kejadian abortus. Diharapkan petugas kesehatan

APPLICATION OF STATIC SYNCHRONOUS COMPENSATOR (STATCOM) AS REACTIVE POWER CONTROL IN DFIG WIND FARM AND GRID INTERCONNECTION SYSTEMS

Published: June 2023

The most difficult aspect of optimizing a wind farm is creating an accurate wind farm model, especially if the farm is connected to the grid. The inconsistency and unpredictability of wind speeds exacerbates this issue. When dealing with wind farms, it is possible that the reactive power addition capabilities of individual wind turbines are insufficient to meet network requirements. This is due to cable losses and line losses between the wind farm and PCC. This study employs a doubly fed induction generator (DFIG) and a Static Synchronous Compensator (STATCOM) compensator to keep the output voltage amplitude more constant. Using two PI controller loops, the STATCOM will generate reactive (capacitive) power if the DFIG voltage is lower. The STATCOM will then absorb reactive (inductive) electricity if the DFIG system voltage is greater. STATCOM's ability to regulate the flow of reactive power can increase the network's stability. By optimizing the network's reactive power, the power factor is increased and stabilized up to 0.99. In addition, the system's harmonics never exceed the 5% limit specified by the IEEE 519-1992 standard.

La tesis describe y analiza el programa Escuela Secundaria para Jóvenes de la provincia de Río Negro. La finalidad del trabajo es indagar en los sentidos que lxs sujetxs le otorgan a esta modalidad de enseñanza secundaria, las respuestas que las escuelas construyen a las demandas de inclusión educativa y el desplazamiento que opera en la política educativa, desde el año 2000 en adelante, en el intento de incorporar nuevos grupos sociales excluidos de la escolaridad secundaria. Se ahonda en las regulaciones generales, la descripción del programa ESJ, los antecedentes históricos de reforma educativa en Río Negro, la caracterización institucional y de la población de estudiantes objeto de las políticas de inclusión educativa, los procesos de contextualización y cambio educativo y la reorganización de la oferta educativa con el fin de promover una nueva modalidad de funcionamiento institucional. Por último, se exploran los sentidos principales que se inscriben en el discurso sobre las ESJ y la identificación del significante inclusión educativa como el sentido que reordena y hegemoniza el campo discursivo.
