Authors: Czapp Stanislaw , Tariq Hanan , Szultka Seweryn , Szultka Agata , Zaitseva Elena , Levashenko Vitaly
Published: April 2022

Residual current devices (RCDs) are most popular devices used in low-voltage installations for protection against electric shock and fire. In cases of high risk of electric shock the application of RCDs is mandatory. Currently, the spread of local direct current (DC) microgrids is widely considered. This creates new challenges for protective systems, in particular those based on RCDs. The main purpose of the research is to test the operation of B-type RCDs by simulating the conditions that may occur in DC microgrids as well as assessment of the effectiveness of electrical safety with the use of such RCDs. The research has revealed that theoretically identical RCDs in terms of technical data can have different tripping properties, including no reaction to residual direct current, which poses a risk of electric shock. This signalizes the necessity of extension of the normative tests performed by manufacturers. The scope of these additional RCDs tests is indicated, from the point of view of the persons’ safety in DC microgrids.
Aging of ground Global Navigation Satellite System oscillators
Authors: Maciuk Kamil
Published: April 2022

Global Navigation Satellite System (GNSS) are widely used in many areas of human life and activity. The proper functioning of GNSS systems depends on several factors, the most important of which is the correct knowledge of time. The position indirectly is based on the knowledge of the distance, which is determined based on time with the knowledge of the speed of the electromagnetic wave. Thus, proper (accurate) knowledge of time (GNSS clock stability) is a key to precise positioning. In this text, the long-term stability of the GNSS station clocks covering the years 1994-2020 was analysed. For this purpose, the corrections of the clocks at selected permanent stations were used, and their stability was determined for all years separately. Then the change of clock stability over time and the search for correlation were analysed. As the results showed, there are clearly differences between four of the type of oscillators analysed. In case of the comparison on an annual basis, no change over time was found.

Authors: Bravo Juan David , Correa Alexandra , Bravo Andrés , Bravo Ricardo , Villada Oscar Alonso
Published: April 2022

Introducción: la diabetes mellitus (DM) es una epidemia mundial. La retinopatía diabética proliferativa (RDP), el edema macular diabético (EMD) y las complicaciones de la diabetes mellitus son las principales causas de discapacidad visual y ceguera en los adultos en la edad productiva. Aproximadamente, 1 de cada 3 personas con DM tiene retinopatía diabética (RD) y 1 de cada 10 tiene RDP o EMD. En el presente estudio se hace énfasis en esta última, siendo el primero con estas características en Colombia.
Métodos: estudio transversal descriptivo donde se incluyeron 1.203 pacientes con diagnóstico de DM atendidos en la jornada “No más ciegos por Diabetes” del Hospital San Vicente Fundación de Medellín, en el 2017 y 2018. Se evaluó la presencia de RD y EMD clínico y sus características  pidemiológicas en un análisis bivariado.
Resultados: del total de pacientes con DM tamizados (1.203), el 5,4 % (65) tenían EMD; dentro de estos, el 7,7 % tenía DM tipo 1 y el 89,2 % DM tipo 2. El 10,8 % tenía RDP, 73,8 % tenía RD no proliferativo (RDNP). En un 93,8 % se hizo diagnóstico de novo de RD. La mediana del tiempo de la diabetes fue de 14 años, con un rango intercuartílico (RIQ) entre 7 y 19,5. La mediana de la hemoglobina glicosilada (HbA1C) fue de 8,3 % (RIQ: 7,1-11). De 65 pacientes con EMD, 28 (56 ojos de los 130 con EMD) fueron estudiados con tomografía de coherencia óptica (OCT) y al 85,7 % se le confirmó EMD. La mediana del grosor macular central fue de 249 micras (RIQ: 231-341) en los pacientes con EMD por OCT (n = 48 ojos).
Conclusión: las complicaciones de la diabetes son más prevalentes en los pacientes con RD. La media del tiempo de aparición de EMD fue similar al tiempo de inicio de las complicaciones microvasculares de la diabetes reportada en la literatura, pero debe ser considerada en el contexto del control metabólico de los pacientes.

Published: April 2022

La enfermedad renal crónica (ERC) se define como la alteración funcional o estructural progresiva de los riñones que persiste por 3 meses o más. Esta enfermedad afecta el 10 al 15 % de la población mundial, siendo la diabetes mellitus, la hipertensión arterial, las glomerulopatías primarias y las enfermedades genéticas las etiologías más frecuentemente asociadas. Sin embargo, en los países pobres se reportan otras enfermedades  ausantes de la ERC; entre ellas la nefropatía mesoamericana (NM). La NM se presenta principalmente en la población masculina joven, lo cual lleva a pérdida de la vida laboral productiva. En Colombia hay una alta prevalencia de ERC con etiología no estudiada (mal llamada desconocida) y hay pocas investigaciones de la ERC en las comunidades agrícolas. Teniendo en cuenta que la población campesina de Colombia se expone a noxas climáticas y laborales similares a Mesoamérica, es posible que esta nefropatía también sea una causa de ERC en nuestra población. El presente artículo hace una revisión de la ERC de las comunidades agrícolas, con el fin de sensibilizar el personal de salud en la importancia de la búsqueda de esta enfermedad en la población vulnerable, lo cual podría impactar de una forma positiva en la salud de los agricultores y campesinos.

Published: April 2022

This research explored the experiences and perspectives of university leaders in Pakistan.  Using a qualitative narrative approach, we explored leadership stories, challenges, and opportunities at various positions unique to the Pakistani context.  Findings underscored the accidental nature of higher education leadership in Pakistan, the significance of mentoring provided by teachers and family support for nascent academic leaders, as well as the challenges these academic leaders face ranging from financial barriers to teaching quality issues, to retention of foreign qualified faculty.  The research offers several policy recommendations including institutionalized leadership training and support for promising leaders; transparency in policies regarding leader appointment, promotion, and succession; support for existing universities rather than expansion; and addressing brain drain due to the attrition of foreign qualified faculty members.
Rethinking the Multilateral Order Between Liberal Internationalism and Neoliberalism/Neoliberalisation Processes
Authors: Knio Karim
Published: April 2022

Discourses on multilateralism and liberal internationalism are replete with warnings about crises. However, theories often only address crises in pragmatic terms, as if they were discreet and isolated phenomena that have little to do with globalized structural tendencies and the specific limitations of knowledge production within the field of international relations (IR). This article initiates a process of reflection on the nature of the crisis of liberal internationalism and the multilateral world order with the help of the pedagogy of crises framework. It identifies the biases contained within IR research and knowledge production as integral to the crises themselves because of the limitations of their engagement with crises solely at the crisis management level. Acknowledging and situating these biases allows us to build a perspective around the notion of crisis of crisis management. This perspective entails a combination of the study of liberal internationalism and neoliberalism to better explain the nature and dynamics of the multilateral world order. This endeavour can offer a fresh take on analysing case studies related to developing countries and outlines a critical focus to inform further research. A brief review of the Chilean example is featured to support this argument, as it shows how the processes that unfold within the multilateral world order are articulated within a local context, and also points to the intimate relations between knowledge production and policy implementation. The article demonstrates the impossibility of understanding the multilateral world order without due consideration of the dialectical relationship between neoliberalism and liberal internationalism. Historically, analyses have focused on neoliberalism as something embedded within liberal internationalism while, in fact, processes of neoliberalisation have become a framework of reference in themselves. That is to say, liberal internationalism, and the study of it, are but a few of the elements that comprise contemporary neoliberalism. Given this, it is argued that systematic academic engagement with neoliberalism/neoliberalisation is essential for a proper understanding of the multilateral world order.

The pandemic process, in general, is a process that creates anxiety due to reasons such as confusion, instability, misinformation and inadequate planning. Within the scope of this study, the assumption that the personality traits of individuals are effective in getting information and taking the required measures while carrying out the health communication during COVID-19 pandemic, and from the question of whether the individual differences can be associated with the inclination for information receipt or not. This scope of this study aims to measure how the communication of the COVID-19 epidemic towards the Turkish people affects the individuals’ preferences for information, the relationships between the sources they trust, and their individual differences based on the Big-5 factors, within the framework of the five major personality traits. This quantitative study, firstly aims to investigate the information-seeking behavior of the Turkish public in relation to their perceptions of COVID-19 and the impact of messages received from the media. Secondly, it is aimed to measure how the COVID-19 pandemic communication affects the relationships among the media sources they trust in their choices of information. While the trust in health care professionals and independent health care associatons were the highest among the individuals who participated in the survey, those who have the responsibility personality trait, trust in the content of COVID-19 messages for government agencies is low.
Demographic and political changes in the United States reflected in the census
Authors: Filippenko Alexandra
Published: April 2022

The census is not only a declaration of changes but also a predictor that provides a glimpse into the future. What makes the 2020 Census unique is that it not only helped us see the demographic picture in great detail, but the process itself reflected the state of the country. Obstructionist legal battles, the COVID-19 pandemic, and wildfires made organizing the 2020 Census the most challenging in U.S. history, but the results were crucial to understanding the nation's trajectory. The U.S. Constitution calls for the census to provide accurate population statistics to allocate budgets to the states and seats in the House of Representatives, and thus in the electoral college. Clearer and more accurate than any other study, the 2020 Census showed that despite the slow growth and aging of the white population, the country has become much more racially diverse (especially among young people), with demographic and age gaps amply offset by immigrants from Latin America and Asia.

Authors: Edyson Edyson , Murgianto Fitrah , Ardiyanto Adhy , Astuti Erika Juli , Ahmad Melina Putri
Published: April 2022

The quality of CPO (Crude Palm Oil) is determined by the Free Fatty Acid (FFA) with the standard value below 5%. High FFA in CPO will cause further difficulties due to low refining rate and quality like rancidness and odor. The objective of this research was to determine the factors that affect the FFA content in CPO. This research was conducted from January until April 2021. Fruit samples were collected from BKLE and PNRE East Kotawaringin and analyzed to Analytical Laboratory PT BGA. The FFA value was determined using the titration method according to Indonesian National Standard (SNI). Based on this research, several factors such as rat and moth attacks, fruit maturity, fruit handling, and delayed delivery to the palm oil mill affected the FFA value. These factors caused an increase in the FFA value up to 41.10%‒204% compared to the average FFA value is only 0.77%‒1.29%. Therefore, minimizing the pre‐processing problem will reduce the potential of FFA value increment so that good quality CPO can be obtained.

Published: April 2022

Sengon (Falcataria moluccana) cultivations still have to face threats from plant diseases. Diseases can be found in nurseries and plantation. Biological agents can be used to control various types of plant diseases and have various advantages. The use of biological agents in forestry plantations must consider the aspects of effectiveness and efficiency. This study aims to examine the effect of various treatment of control technology packages on the incidence of major diseases, and to determine the financial feasibility of various disease control technology packages for sengon in nurseries. The research was conducted through interviews to explore cultivation techniques and production costs. In addition, experiments were carried out on the application of various disease control strategies using commercial formulations of biological agents. The commercial formulations of biological agents used were Rhizomax, Primagrain, Trichowish, Kayabio, Bio-Hara Plus, and fungicide Dithane M-45 80 WP. There were two treatment packages of new technology that have an effect on increasing the growth of sengon at the beginning of growth stage, namely P1 (BioHara Plus and KayaBio) and P2 (Rhizomax and Primagrain) treatments. All treatments of the new technology package had no significant effect on increasing the survival rate and suppressing the incidence and severity of disease in sengon seedlings. All new technology package treatments can generate profits even though the value is smaller when compared to existing technology treatments. All the new technology package treatments have an R/C ratio of more than 1 so that they are feasible to be applied by farmers.   Keywords: biological control, feasibility, plant diseases, nurseries, Falcataria moluccana
AVALIAÇÕES REMOTAS EMERGENCIAIS EM UM CURSO DE LICENCIATURA EM MATEMÁTICA A DISTÂNCIA
Authors: Jocemar de Quadros Chagas  , Elisangela dos Santos Meza  , Ana Lúcia Pereira
Published: April 2022

Este artigo apresenta o processo de adaptação das avaliações em um Curso de Licenciatura em Matemática ofertado na modalidade a distância de uma universidade pública no estado do Paraná, durante o período de pandemia da Covid-19. Como contextualização, apresenta-se brevemente a universidade e o Curso de Licenciatura em Matemática, assim como o histórico da oferta a distância do referido curso no âmbito da Universidade Aberta do Brasil (UAB). O processo avaliativo constante no Projeto Pedagógico do Curso é, também, apresentado, assim como algumas pertinentes reflexões acerca da avaliação em Matemática. Na sequência, destaca-se a adaptação das avaliações finais (tipicamente presenciais) ao formato remoto, motivada pelas restrições de mobilidade e aglomeração impostas pelo poder público como tentativas de contenção da pandemia do novo coronavírus, sempre ressaltando que Ensino Remoto Emergencial (ERE) não deve ser confundido com Educação a Distância (EaD). As estratégias emergenciais apontam que a inserção no AVA do registro das resoluções, realizadas durante as avaliações, motiva a desenvolver um olhar mais atento à forma como cada licenciando organiza o pensamento e raciocínio matemático. Além disso, a manutenção da exigência de produção escrita pelos estudantes nas atividades avaliativas serviu como um processo de “experimentação” e “reﬂexão” para professores e coordenadores do curso.

Published: April 2022

Recent increasing rates of COVID-19 cases, hospitalizations, and deaths among non-Hispanic Whites have led to declining rate ratios at a time of continuing high burden of COVID-19 in American Indian/ Alaska Native, Asian/Pacific Islander, African American, and Hispanic/Latino populations. The use of all epidemiological tools, including rate ratios and actual rates per 100,000 population, provides a more comprehensive assessment of the magnitude and trends of racial and ethnic disparities in COVID-19.Ethn Dis. 2022;32(2):109-112; doi:10.18865/ed.32.2.109

Objective: To determine if race-ethnicity is correlated with case-fatality rates among low-income patients hospitalized for COVID-19.Research Design: Observational cohort study using electronic health record data.Patients: All patients assessed for COVID-19 from March 2020 to January 2021 at one safety net health system.Measures: Patient demographic and clinical characteristics, and hospital care processes and outcomes.Results: Among 25,253 patients as­sessed for COVID-19, 6,357 (25.2%) were COVID-19 positive: 1,480 (23.3%) hospitalized; 334 (22.6%) required intensive care; and 106 (7.3%) died. More His­panic patients tested positive (51.8%) than non-Hispanic Black (31.4%) and White patients (16.7%, P<.001]. Hospitalized Hispanic patients were younger, more often uninsured, and less likely to have comorbid conditions. Non-Hispanic Black patients had significantly more diabetes, hyperten­sion, obesity, chronic kidney disease, and asthma (P<.05). Non-Hispanic White patients were older and had more cigarette smoking history, COPD, and cancer. Non- Hispanic White patients were more likely to receive intensive care (29.6% vs 21.1% vs 20.8%, P=.007) and more likely to die (12% vs 7.3% vs 3.5%, P<.001) compared with non-Hispanic Black and Hispanic patients, respectively. Length of stay was similar for all groups. In logistic regres­sion models, Medicaid insurance status independently correlated with hospitaliza­tion (OR 3.67, P<.001) while only age (OR 1.076, P<.001) and cerebrovascular disease independently correlated with in-hospital mortality (OR 2.887, P=.002).Conclusions: Observed COVID-19 in-hospital mortality rate was lower than most published rates. Age, but not race-ethnicity, was independently correlated with in-hospital mortality. Safety net health systems are foundational in the care of vulnerable patients suffering from COVID-19, including patients from under-represented and low-income groups.

Published: April 2022

The crisis caused by prescribed opioids and their related side effects are a public health problem worldwide. Most of these are prescribed for coping with chronic pain. The coexistence of opioid use disorder (OUD) in patients with chronic pain represents a complex challenge due to the need for managing both pain and OUD. The aim of this systematic review is to evaluate the efficacy of feasible treatments for this population with OUD and comorbid chronic pain for both conditions. A systematic database search has been performed using Cochrane Library, MEDLINE, PsycINFO and ClinicalTrials.gov in compliance with PRISMA guidelines. Eligible articles addressed the outcomes in chronic pain patients with comorbid opioid use disorder after treatment interventions were applied. Of 593 identified articles, nine were eligible for qualitative review (n = 7 pharmacological interventions; n = 2 psychological interventions). Methadone, buprenorphine, cognitive-behavioral and mindfulness showed promising results, but data were inconclusive (<2 RCT with low risk of bias). It is unclear whether the opioid agonist treatment should be maintained or tapered and which drug should be prescribed for the opioid substitution therapy (methadone or buprenorphine/naloxone). Mindfulness and cognitive behavioral therapy have a discrete effect on improving negative affect but not pain. The therapeutic approach might be individualized under a shared decision-making basis.

Introduction: The latest corona virus (Covid-19), centered in one of the provinces in China, has spread to various countries. World Health Organization (WHO) Emergency Committee declared a global health emergency. Covid-19 virus based on several studies can be transmitted from human to human. Knowing the ways and media of transmission of Covid-19 is crucial so that transmission prevention can be done immediately. Objective: The purpose of the study to know the specific transmission of Covid-19 virus and how to prevent it that can be done. Method: The research was conducted using two databases, namely: Google scholar and Pubmed 2019-2020. Articles that meet the inclusion criteria namely methods, media of transmission and management of prevention of Covid-19 transmission are then reviewed. Results: Covid-19 transmission from human to human can be caused by close relationships such as family, close relatives, close friends, contact with people who are already infected. Transmission occurs through coughing, sneezing and aerosols. Transmission by air contributed to the Covid-19 outbreak. Less than one meter distance from an infected person has the potential for transmission. In the mechanism of infectious disease, transmission through vomiting plays a greater role than droplets. Discussion: Covid-19 virus has spread to more than 100 countries. Appropriate measures must be taken immediately to prevent the spread of the epidemic. The main purpose of prevention is to break the chain of transmission from human to human by separating people who have the potential to transmit it to others. One effort to achieve these goals is self-isolation at home or in health services. Social restrictions are also important to prevent spread in people who have not been detected by Covid-19. Conclusion: Because of its rapid and wide spread, it is important to prevent proper transmission to avoid threats to health, and the spread of this virus. By knowing Covid-19 transmission can be used as a guide for prevention and control both at home, and in health care.

Background: Hypertension is still a big challenge for health development in Indonesia because of the high prevalence rate of hypertension. Hypertension is usually not recognized by the public because the symptoms are unclear and resemble health complaints in general. Although not treatable, prevention and management can reduce the incidence of hypertension and the diseases that accompany it. Basic Health Research in 2018 showed that people with hypertension reached 34.1% of the total population of Indonesia. This literature review aims to analyze the factors that influence the incidence of hypertension. Method: This study uses a descriptive analysis method with a literature review approach. Sources of data use secondary data, namely in the form of books, scientific literature as well as from the results of research conducted by previous researchers related to the discussion of factors that influence the incidence of hypertension. The method of searching for articles or journals uses the keywords "Risk factors for hypertension" or "factors that influence hypertension". The inclusion criteria used were journal factors related to the incidence of hypertension which could be accessed in full text. The journal year used is limited to 2012-2020. Results: Literature analysis in 12 journals found that age, gender, obesity, heredity, stress, physical activity and lifestyle factors can influence the incidence of hypertension. Conclusion: There is a relationship between age, gender, obesity, heredity, stress factors, physical activity factors and lifestyle factors with the incidence of hypertension.

The COVID-19 pandemic had an impact on nursing students’ academic and clinical performance. Nursing institutions have provided remote learning to continue the learning process. However, students have met several obstacles that caused a decrease in the quality of learning. Remote learning for education requires the support of information and communication technology. However, studies related to how the COVID-19 pandemic affected nursing education in Indonesia are still rarely done. Accordingly, this study was conducted to evaluate the implementation of remote learning for nursing education during the COVID-19 pandemic. A cross-sectional study was conducted with 331 members of the Association of Indonesian Nurse Education Center (AINEC). The instrument used was the Guidelines of Filling Out Remote Learning. The results showed that 51% of the study programs implemented remote learning, while 69% of the regulations for remote learning were created by rectors. The most common teaching materials were visual, text, and audio-visual content. These materials were distributed through WhatsApp Group, Learning Management System (LMS), and video conference. To support the process of remote learning, nursing institutions need to improve information technology staff and cooperate agreement with other institutions. Overall, the remote learning process needs to be further improved to increase the students’ learning quality.

The aim of the work was to summarize the results of cholera monitoring in 2021, to assess current trends in the development of the epidemic process, and to predict the epidemiological situation in the Russian Federation for 2022. It was established that within the period of 2012–2021, 4117264 cases of cholera with the spread of infection across 83 countries on all continents were registered in the world and there was a downward trend in the incidence in Asia and Africa. The dynamics of monthly morbidity in 2021 was associated with emergencies as factors of epidemiological risk. Epidemics and outbreaks of cholera were documented against the background of COVID-19 pandemic and laid a double burden on healthcare systems. At the same time, based on the overview of the results of cholera monitoring in the constituent entities of the Russian Federation, it was shown that the forecast of epidemic well-being given for 2021 was fully justified. It has been determined that the increase in the number of non-toxigenic strains of Vibrio cholerae O1 (67) isolated from water bodies compared to 2020 (25) is mainly due to the appurtenance of a number of isolates to clonal complexes. The study of phylogenetic relation has demonstrated that the detection of strains with genotypes which were previously identified in the isolates evidences the persistence potential. The identification of strains with new genotypes, which were earlier established in the strains circulating in other territories, pointed at the possibility of the occasional importations. The forecast of the epidemiological situation on cholera in Russia for 2022 is associated with the continuous existence of risks of introduction. If these epidemiological risks are not realized, a favorable epidemiological situation is predicted regarding this infection in the country. It is expected that the detection of epidemiologically insignificant strains of V. cholerae O1 in environmental water bodies, along with their clones and/or clonal complexes, will remain, including strains that may be an etiological factor in sporadic cases or outbreaks of disease.

The development and production of unconventional reservoirs, such as the Bakken Formation, have become a resolved mystery for operators in North America since the arrival and advancement of horizontal drilling and hydraulic fracturing technologies. As a result, unconventional reservoir assets became the central focus of the oil and gas industry at the state, national, and global levels. The produced water from these activities in the Bakken Formation have high salt contents (110,000–350,000 ppm) total dissolve solids (TDS) and can pose significant challenges to the environment if not treated. Deep injection into disposal wells is the routine method used to get rid of the Bakken produced water. However, there have been some concerns that unrestrained injections, in addition to polluting the groundwater, could potentially lead to seismic activities either at the time of injection or in the near future. To diminish the environmental impacts that may be associated with induced seismicity, including the reduction of the costs of water acquisition, the produced water can be treated and reused in the hydraulic fracturing processes. Also, the treated water could be used for irrigation purposes, for power generation, and coal mining operations. The issues of waste water and residual oil high in TDS are challenges yet to be effectively addressed despite preceding research and studies on advancing produced water technologies. The goal of this study is to explore all applicable ways by which the produced water from the Bakken Formation can serve as a replacement base fluid for use with polymers like the high-viscosity friction reducers (HVFRs) to create hydraulic fracturing fluids that can be stable with reservoir conditions and also be able to minimize environmental impacts and cost of operations. Experimental investigations using the high-salinity produced water from the Bakken Formation with HVFRs were carried out. The studies included a base case that served as a bench mark for comparing the effectiveness of the other scenarios. The results indicate that the Bakken hyper-saline produced water can withstand effect of heavy metals, salinity, hardness and remain stable through different shear rates (66–330 s−1) when treated with higher dosages [4–8 gal/1,000 gal (gpt)] of HVFRs. Filtration and dilution were the only methods used on the Bakken Formation produced wate for this research
Liquid Loading in Natural Gas Vertical Wells: A Review and Experimental Study

Published: April 2022

Liquid loading in natural gas wells is one of the main causes of decline and eventual cease of production. Identifying the onset of liquid loading and its impacts on production is vital in production optimization of gas wells. In this study, a new state-of-the-art experimental facility is used to analyze two-phase flow parameters, such as liquid and gas velocities, pressure drop, liquid holdup, and flow pattern, and study the onset of liquid loading. Experiments are conducted using air and water in a 0.0508-m (2-in.) internal diameter (ID) vertical flow loop. The facility is designed to eliminate any source of disruption to the flow in a temperature-controlled indoor environment to avoid changes in fluid properties. A wide range of data are collected related to the onset of liquid loading and in the churn region. The acquired data are compared with other studies to ensure the accuracy and repeatability of the tests.

A quantitative method is developed to predict the onset of liquid loading, namely, the positive frictional pressure gradient (negative pressure drop). A comparison is made between the visual observations for flow pattern transition, positive frictional pressure gradient, and minimum pressure drop. Overall, the results show that the positive frictional pressure gradient approach can provide a better estimation of the onset of liquid loading than the minimum pressure drop approach. Additionally, Tulsa University Fluid Flow Project (TUFFP) unified model (v2016) and OLGA (v2016.2.1) are used to evaluate the average pressure drop, liquid holdup, and flow pattern. Furthermore, the liquid film reversal model, liquid droplet models, and inflection point approach are included in the comparison of the onset of liquid loading with experimental data. The OLGA model predicts the results more precisely than other models. The comparison with the experimental data indicates that inaccurate flow pattern predictions could significantly increase the relative errors in pressure drop and liquid holdup. In addition, the evaluation of OLGA results suggests the need to develop a model for churn flow, as the relative error increases sharply in the churn flow with the model predicting the transition to slug flow.
