Farmers’ perception of climate change and gender sensitive perspective for optimised irrigation in a compound surface-ground water system
Authors: Dawit Meseret , Dinka Megersa Olumana , Halefom Afera
Published: July 2023

Water is becoming a scarce resource due to the immense intensification of agricultural activity, climate change, and demographic pressure. Hence, information on water use/management and their associated management practices is essential for selecting, planning, implementing, and monitoring schemes that optimise water use to meet the increasing demand related to basic human needs and welfare. This study presents the farmers’ perception of climate change from a gender sensitive perspective to promote adaptation and optimise irrigation/agricultural productivity in a compound surface-ground water system within the Anger sub-basin (Ethiopia). The study results showed that climate change affects water demand and supply routes in which more than 65% of the decrease in lake water level is due to climate change and overuse of surface water. The research findings show that women’s recognition and apprehension of climate change is much greater than men’s. Thus, women’s role in farming is important for ensuring food security at the household level. Gender sensitivity and can play a role in preventing the change in climate through optimising irrigation efficiency and suggesting the need for further research on its application to science. The study demonstrates that women’s participation in agricultural tasks, crisis management, and informal institutions is more vigorous than men’s. On the other hand, the understanding and communication of farmers is based on experience and concerns about the climate impact. Moreover, studies showed that climate change has a potential impact on the access to water supply for agriculture, urbanisation, and the environment. Therefore, there is a need to assess the dynamics of surface- groundwater interaction as affected by climate change and gender inequality to optimise the irrigation system.

Published: July 2023

OBJECTIVE

To describe the clinical, laboratory, and ultrasonographic findings; treatment; and outcome of cattle with mesenteric torsion (MT).

ANIMALS

61 cattle with MT between November 1, 1986, and December 31, 2019.

METHODS

Medical records were retrospectively reviewed. Results were compared for cattle that survived versus did not survive to hospital discharge.

RESULTS

All cattle had abnormal demeanor. The most common clinical signs were tachycardia (80.3% [49/61]), tachypnea (65.0% [39/60]), and lower rectal temperature (59.3% [35/59]). Signs of colic occurred in 65.6% (40/61). The most common gastrointestinal findings were an empty or almost empty rectum (100% [59/59]), reduced or absent motility of the small intestines (96.6% [57/59]) or rumen (93.2% [55/59]), positive ballottement and/or percussion and simultaneous auscultation on the right side (91.7% [55/60]), and dilated small (49.2% [29/59]) and large intestines (spiral colon and/or cecum, 44.1% [26/59]) detected during transrectal examination. The most common laboratory findings were acidosis (82.6%, [38/46]) hypermagnesemia (74.5% [35/47]). Ultrasonographic findings included reduced or absent small intestinal motility (86.7% [26/30]) and dilated small intestines (83.8% [31/37]). The spiral colon was dilated in 32.4% (12/37) of the cattle. Eighty-two percent (50/61) of the cattle underwent right flank laparotomy and the MT could be reduced in 34.4% (21/61). Twenty-three percent (14/61) of the cattle survived to hospital discharge, and 77.0% (47/61) were euthanized before hospital discharge.

CLINICAL RELEVANCE

Dilated small and large intestines (spiral colon, cecum) combined with a severely abnormal demeanor and tachycardia are characteristic findings in cows with MT. Immediate surgical treatment is paramount.
The Role of Climate Change News in Pharma Industry
Authors: Anghel Bogdan Ionut , Lupu Radu
Published: July 2023

In this article, we aim to study the role of climate change news in the European Big-Pharma companies returns. The goal of the research is to explain if the sentiment of the news posted on Twitter can explain the market movements, even if current global events may affect stock prices. The previous literature reveals the impact of climate change in the economy, but in the field of pharma companies, there is less information of how climate change affects the evolution in the stock market. We used the VADER methodology to examine and analyze the climate change news posted on Twitter. This allows us to extract the sentiment and use it to study the dependence between sentiment score and the evolution of the European Big-Pharma companies. To examine the relation, we use Ordinary Least Squares regressions and Quantile Regression. Our results reveal the fact that there is no significant dependency between the sentiment score of the news published on Twitter by the biggest newspapers and the price increase of the European Pharma companies stocks. We observe a small increase in dependence when we use the sentiment score with 1 day lag in the Ordinary Least Squares regressions and another improvement in results with Quantile Regression.
Project Management in the Wind Energy Field. Case Study: Evaluation of Wind Energy Projects through the Net Present Value
Authors: Maassen Maria Alexandra
Published: July 2023

Wind energy has become one of the main sources of green energy having reached a peak of 220 GW installed wind capacity in 2020 in the European Union according to the TPA report (2021). With the expansion of wind energy installments, project management in the field also had numerous challenges in terms of estimating wind energy projects worth implementing in terms of capital and operating costs, as well as benefits. The present article presents the main method of evaluating wind energy projects, namely the net present value applied on specific costs and benefits of a wind energy installment in order to determine whether it is worth implementing or not. The paper contributes to the scientific literature by applying this method of analyzing wind energy projects before installment, a characteristic that is compulsory for project management in the field in order to adapt the project if needed in terms of costs or revenue streams.

Smart Homes: Analysis of IoT Security Indicators
Authors: Vasilescu Nicolae-Gabriel
Published: July 2023

Smart homes often face security problems caused by internal or external factors that can bring different problems both in terms of IoT components and at the overall level. In the paper, a prototype is defined to analyze several indicators to measure the extent to which the residents’ requirements are met. At the level of scientific literature, the analysis is done from the overall point of view, the interest here being for the IoT components taken individually to see the impact in the daily life of the people who live in that house. The problem of the interdependence of the indicators and how they are managed individually both manually and by remote control is a point of interest in the analysis carried out, here both the technical part and the business part and adaptation to the requirements and the trend of the future come into discussion. Based on the current situation and trends, some guiding steps were identified regarding the appropriate use of the analyzed indicators. The security of the smart home can suffer changes if a new element is inadequately integrated into the system circuit, affecting both the other sensors, but also allowing attacks on the personal space of the people who live inside or who have sensitive data that can be accessed once with access to the system.
International Cooperation and Solving Transfer Pricing Disputes: A Discussion about Mutual Agreement Procedures
Authors: Lupu Mihai
Published: July 2023

The mutual agreement procedure is the main instrument available to both taxpayers and tax administrations for mitigating international double taxation arising from transfer pricing adjustments. Although it may apply to cases generated by other tax topics, this article refers strictly to its application in the context of transfer pricing. Ensuring this mechanism operates as smooth as possible is one of the factors contributing to efficient cross-border economic flows of goods and services and their fair taxation, eliminating the risk for multinational groups of paying more taxes than necessary (as a result of transfer pricing adjustments performed by tax authorities). As one of the organisms promoting international cooperation and economic wellbeing, the OECD tracks the performance of member and non-member states in relation to the effective implementation of mutual agreement procedures. The process is not aimed at evaluating the results of one specific country, but rather to offer a global perspective. Through literature review as well as secondary data analysis derived from the annual reports prepared by the National Agency for Fiscal Administration in Romania and the OECD, this article aims at presenting how the Romanian tax authorities are handling mutual agreement procedure cases, as a base for future improvements. Although the Romanian tax authorities have been constantly involved during the last 7 years in solving double taxation cases through mutual agreement procedures, work is still needed in order to make the process more efficient, considering that their results are still significantly below the high-achieving countries, as presented in the OECD reports.
The Evolution of Economic Disparities in Romania during the COVID-19 Pandemic: A Comparative Analysis of Pre-Existing and Emerging Challenges
Authors: Antonia Mihai , Simion Luciana
Published: July 2023

The COVID-19 pandemic has had significant impacts on Romania, exacerbating existing inequalities in the country. Economic disparities between counties were deepened, with counties with higher GDP per capita and diverse economic activities faring better than those with lower GDP per capita and narrow economic activities. The pandemic also led to a decline in population numbers, with most counties in the historical regions of Muntenia and Moldova experiencing below-average declines. In addition, the pandemic had a significant impact on the average life expectancy in Romania, highlighting the need for targeted policies and interventions to address these regional inequalities. Lastly, the pandemic negatively affected labor force participation rates in Romania, further highlighting the need for policymakers to implement measures to encourage more individuals to enter and remain in the labor market, particularly in regions with lower participation rates.

This review aims to provide an integrated picture of the main economic policy responses in the EU; It presents an analytical description of the measures launched both at the EU and Member States’ levels and identifies risks, challenges and opportunities for the future of EU economic coordination.
An Analysis of Semiconductor Stocks as an Opportunity for Portfolio Diversification
Authors: Trucmel Irina-Maria
Published: July 2023

The semiconductor industry is a key driver of technological progress due to essential parts that are integrated in widely used electronic devices nowadays. Given its critical importance, this industry is constantly evolving in order to adapt to market requirements led by fast-paced consumer trends. Meanwhile, the global supply chain is undergoing pressure from other conditional factors, mostly the pandemic and trade restrictions in recent times. With potential to grow due to digitalization, semiconductor companies can be an attractive option to invest in. Building an investment portfolio is a challenging process regardless of the risk preference of an investor. Based on the concept of diversification, combining low-correlated assets from various industries can lead to an overall efficient portfolio with acceptable risk levels. The aim of this study is to analyze the evolution of eight selected semiconductor stocks from 2018 to 2022 and evaluate their relative performance to the benchmark index by using descriptive statistics and risk metrics drawn from their daily returns. Having an insight on the results obtained from historical data allows us to examine whether diversifying portfolios with semiconductor stocks represents an opportunity, mainly contributing to a pre-selection of stocks to mitigate the risk and support the investment decision.

Authors: Stoian Marta
Published: July 2023

Leadership for the digital and entrepreneurial society is a relatively new and emerging area of study, as the rapid pace of technological change has brought new challenges and opportunities for leaders. Forasmuch as digital society continues to evolve and grow, and as COVID-19 has had a significant impact on leadership practices and has brought about some notable changes in how leaders approach their roles, new leadership models are emerging to meet the unique provocations and chances of this context. The scientific literature on this specific topic is still emerging, but some key themes have already come up emphasizing the importance of agility and adaptability as organizations have to rapidly pivot their operations in response to the increasingly necessary digital expansion accelerated by the pandemic. As traditional business models are disrupted, leaders who are able to effectively leverage new technologies while thinking creatively and taking risks are more likely to succeed. Therefore, considering that the subject is still in its early stages, the research topic is to examine the leadership models that should be utilized in order to improve the digital and entrepreneurial context answering the main research questions related to the steps and leadership practices that will make a significant difference in both digital and entrepreneurial societies. The past literature on empirical and theoretical topics is compiled via a systematic review. An analysis of the content that is qualitative and descriptive was planned. Scopus, Web of Science or Google Scholar search results were of great help in carrying out the study and various leadership models were examined. The paper’s theoretical contribution is the definition of a set of rules and criteria on where to focus on leadership. The collection of data for new performance, ownership, efficiency, and business value generation indicators is promoted at all levels.

Young, Wild & Entrepreneurial: Generation Z’s Affinity for Entrepreneurship
Authors: Cirstea Petronela , Anagnoste Sorin
Published: July 2023

Generation Z is a cohort of contrasts - youth growing with a life fuller of possibilities than ever before, but also into a world filled with challenges. Born between approximately the mid-1990s and 2010s, they are no longer children, but emerging as today and tomorrow’s leaders, innovators, and entrepreneurs.

Studies have already revealed that this generation has a high affinity and strong abilities towards entrepreneurship. Digitally-savvy and with a global mindset, yet troubled by anxiety and inexperienced, Zoomers have a starting point which, depending on one’s perspective, can be either troublesome or advantageous.

The paper includes a review of the current state of research on the topic, followed by owned research examining how Zoomers position themselves in regards with entrepreneurship, ending with conclusions, observations, and recommendations. As both the authors either identify as, or teach, Generation Z ourselves, this topic holds professional, academic and personal dimensions.

Youth is history in the making. Understanding, on a deeper level, the reasons and goals, the challenges and opportunities which make up Generation Z’s professional ecosystem will ensure the best management of the economic force represented by Generation Z’s entrepreneurial intent.

Suspiciousness and Fast and Slow Thinking Impact on Trust in Recommender Systems
Authors: Rad Dana , Cuc Lavinia Denisia , Lile Ramona , Cuc Paul Nichita , Pantea Mioara Florina , Anta Darius
Published: July 2023

By offering consumers more proactive and individualized information services, recommender systems have proven to be a significant answer to the problem of information overload. And collaborative filtering approaches have proven to be an important component of many such recommender systems, allowing for the development of high-quality recommendations by harnessing the preferences of communities of similar users. In this study, we argue that individual personality traits may play an essential role in ensuring general end-user confidence in recommender systems. Individual elements to be examined include social suspiciousness as a personality feature and Daniel Kahneman’s fast and slow thinking styles, which distinguish between two modes of thought: System 1 is rapid, instinctual, and emotive, while System 2 is slower, more deliberate, and more rational. Due to a lack of explanation or inaccurate recommendation results, users may not trust current recommender systems, which poses a significant challenge for those systems. As such, having a trustworthy recommender system is essential. Three different trust-aware recommender system types are analyzed systematically in this study: robust systems that filter misleading information such as spam and fake news; social aware conscious systems that benefit from users’ social connections; and explainable systems that offer justifications for recommended products. On a sample size of 487 Romanian respondents, in an online survey, we have analyzed the impact of individual factors on the trustworthiness of the three types of recommender systems. Results show that fast thinking fully mediates the relationship between social suspiciousness and trust in all three types of recommender systems.
Organizational Commitment: A Bibliometric Analysis
Authors: Marin Radu
Published: July 2023

For decades, both researchers and management specialists along with human resources specialists have tried to explain, understand, measure and evaluate the consequences of the main organizational phenomena considered to be responsible for the employee performance, for their intention to stay within or to leave the organization, as well as for other phenomena with notable implications on the performance of organizations, such as absenteeism and scrap’s reduction. Organizational commitment is one of the most important organizational behaviors that leads to a better employee performance and a decrease intention to leave the organization, to reduce absenteeism and to reduce the negative behaviors manifested by employees in relation to the organization. Also, the existence of a high organizational commitment leads to the creation of an innovative working environment. Currently, organizational commitment is one of the most important topics, analyzed both in the academic literature and among practitioners. This is the reason why, in this paper, we aimed to analyze the evolution and structure of the scientific papers that approached this subject, using the method of bibliometric analysis. The data needed in order to perform this analysis was extracted from both the Web of Science and Scopus. Based on the collected data, the evolution in time of the number of publications that approached this subject was analyzed, also the names of the authors who with the most contributions in approaching this subject, the countries where these publications were present, the countries of origin of the authors between which most collaboration relations were established. Also, the intensity of the links between the most used keywords in relation to the analyzed keyword was analyzed, as well as the intensity of the links between the main keywords related to the term organizational commitment.

Published: July 2023

In the current economic context, at the global level, the problem faced by organizations is determined by the means of environmental protection and the reduction of the negative effects of the ongoing activities, adopted at the organizational level. Thus, the objective of the research in this paper is to identify concepts such as sustainability/sustainable development within organizations and their financing mechanisms.

The aim of the research is to contribute to increasing the knowledge of the tools for the sustainable development of companies, through the new sustainability approach that aims to re-educate both the business environment and the consumer, the ESG standard being a competitiveness trigger. The volatility, uncertainty, complexity and ambiguity of the mechanisms developed and adopted at the level of organizations, being able to be reduced by adopting effective strategies based on ESG principles at the managerial level.

The research methodology includes both secondary data collected from European Commission information sources, articles and existing specialist content in the direction of the development of ESG factors and the VUCA world, as well as the authors’ interpretation based on the collected information.

The existence of funding instruments such as the Horizon Europe, Life Programme, Innovation Fund (IF) programs granted through non-reimbursable development projects to encourage sustainability directions in terms of economic, social and governance factors within organizations is demonstrated. Also, the financing of sustainable development projects contributes to the consolidation of the VUCA phenomenon, namely the realization of complex projects in both the public and private sectors, in a volatile market with unpredictable factors as a result of the globalization process.

Meters Wide: A Failed Mediatic Annexation of Sporting Heroes During Pandemic Times?
Authors: Roşca Vlad I. , Burnar Vasile-Teodor
Published: July 2023

This sports media research uses a single case study approach to investigate the effects of the COVID-19 pandemic on the mediatic consumption of sports heroes. The case of airing the “3mm” documentary film about WTA tennis player Simona Halep on Romanian television is being analyzed. The theoretical framework is set around the concept of parasocial interaction specific for the mediated relationships between sports fans and their favorite sports brands. The research question asks about the factors induced by the COVID-19 pandemic that might have influenced the rather low audiences of the broadcasted documentary. Results show that, indeed, the COVID-19 pandemic might have well had a considerable impact upon audience figures, mainly because, due to the pandemic situation, the patterns of parasocial interaction between sports fans and sports brands have been altered. The paper discusses the changes in parasocial interaction which occurred due to the pandemic.

Circularity and Municipal Waste in Romania An Evaluation between 2011 and 2021
Authors: Năstase Luiza Loredana
Published: July 2023

With the aim of moving to a circular economy, as specified in the European Union amending Directive 2018/851, by the year 2025, member states must reach a level of at least 65% by weight in the preparation for reuse and recycling of municipal waste, with the possibility of a 5-year postponement, under certain conditions. However, the generation of municipal waste has registered an increasing trend, due to the low recycling rates in many member states of the European Union, the low inefficiency of the collection systems and the poor implementation of the legislation in force. Through the research carried out, we want to highlight the trends regarding the generation, treatment, and recycling rates of municipal waste in Romania, in the period 2011-2021, but also the degree of fulfillment of the assumed targets regarding municipal waste. For this, we used the European databases available for the indicators selected in the research, as indicators of a circular economy. The analysis undertaken showed that in the last decade the amount of municipal waste per capita has increased, but it is far below the European Union average. Regarding the treatment of municipal waste, it is noted that the main operation is still landfill disposal and other similar operations, with an increasing trend compared to the base year of the analysis and contrary to the specifications of the European Union Framework Directive on waste, according to which waste disposal should be the last choice, when we consider the hierarchization of waste. The recycling rate of municipal waste was only 11.3% in 2021 and put Romania in last place in the ranking of the member states of the European Union. The bio-waste recycling rate did not have good values either; this was 14 kilograms per capita, decreasing in the analyzed period and well below the European Union average.
Clusters, Business Planning and Economic Growth: Stockholm’s Artificial Intelligence and Big Data Cluster
Authors: Călinescu Gabriela
Published: July 2023

Clusters, which are examples of Porter’s diamond in action, may foster creativity. Regional economic development, innovation efforts, and clusters are interdependent. Artificial Intelligence and Big Data can perform activities at a higher level than humans. Recent studies indicate that they are gaining popularity because they can be used to collect, organize, and analyze vast, varied data sets in order to reveal hidden patterns and trends that may be applied to a number of problems. How can Stockholm’s Artificial Intelligence and Big Data cluster enhance its competitiveness in light of these factors? How can it be made more appealing? To address these research issues, qualitative research was undertaken using the case study approach and statistical data mostly gathered from the Global Competitiveness Report. Among the most important aspects of this article are the analyses of competitiveness, cluster performance, and main actors of the cluster. The study indicates that Stockholm, the capital of Sweden, has the potential to become one of the world’s largest proponents of Artificial Intelligence and Big Data, since it is far more developed than other cities. In addition, a strategy to strengthen the cluster’s competitiveness by stressing the implemented actions is proposed. This paper was co-financed by The Bucharest University of Economic Studies during the PhD program.
Is There Any Effect of ESG Scores on Portfolio Performance in South Africa?
Authors: Sandu Diana-Mihaela
Published: July 2023

This study compares the performance of five portfolios built according to the level of integration of environmental, social and governance values in the case of South Africa, over the period of four years from 2 January 2019 to 29 December 2022. The portfolios were built according to (1) the two dimensions of ESG ratings (responsible and irresponsible) and (2) the two levels of ESG implication (partially and significantly), and there is also a portfolio for non-engaged companies (no-reporting). Many recent studies comparing ESG and non-ESG portfolio performance have reported contradictory results so that this debate remains inconclusive. The main question I explore is whether portfolios integrating ESG values really matter in the case of a developing country with many economic and social challenges, as in the case of South Africa. For the purpose of the study, I have used four risk-adjusted measures (Sharpe ratio, Treynor ratio, Modigliani-Squared and Jensen’s alpha) for the performance evaluation. This study found an adverse effect of ESG on portfolio performance. Overall, the ESG Irresponsible portfolios achieved a better performance as compared to its counterparts. The study findings contribute to and enrich the academic literature by comparing the performance of five ESG portfolios in the South African context.

What Digital Technologies are Used Today by Accounting Firms to Deliver Services
Authors: Isip Adrian
Published: July 2023

Nowadays for carrying out their activity, enterprises rely a lot on information and communication technology. In a dynamic business environment characterized by many uncertainties, the accuracy and speed of information production are crucial. Internal and external accountants prepare the information needed by managers to make decisions. Advances made in information and communication technology ensure near real-time information and instant communication. This paper investigates digital technologies used today by accounting firms to deliver services considering the driving factors for adoption and the impact of their use. We mobilized institutional theory as a theoretical framework, accounting services industry from Romania as context and semi-structured interviews as research methods involving 17 accounting experts. The results indicated that adoption of digital technologies within accounting firms is mainly driven by coercive and mimetic isomorphic pressures coming from the state and competitors. International and local accounting firms affiliated to international networks implemented digital technologies to a greater extent compared to local independent accounting firms which intend to invest more in digital technologies when the electronic invoicing system becomes mandatory for all enterprises. For clients with a large amount of data, accounting firms use import interfaces to exchange data between information systems. Cloud applications and virtual meeting platforms enable the provision of digital services and today because of digital technologies large companies can also outsource their accounting services. Some accounting firms are required by contract to use digital technologies provided by their clients. Accounting experts claimed that automation solutions decrease the processing time of documents and ensure a similar quality to the manual work performed by human employees. Showing what digital technologies are used today and their impact for accounting services industry represent the main contributions of our study. Our research has implications for smaller accounting firms since our findings can represent for them an important source of information.
The role of actions with the transposition formula in the development of Roman business law
Authors: CIUTACU ionuț
Published: July 2023

Towards the end of the Republic, the Roman state experienced an unprecedented development. The Roman business environment needed flexible legal documents, able to keep up with the fast pace imposed by commercial documents. The legal acts of the old Roman Law did not correspond to the requirements of the exchange economy, as they were cumbersome and formal. The Romans were conservative and did not easily accept deviation from the rigors of the old Roman Private Law. For this reason, they created a new procedural system, the formal procedure, with the help of which they managed to update the norms of Roman Law. One of the most interesting legal procedures specific to this system was the action with the formula with transposition, because in this way the lawyers contributed to the development of Roman business law.
La orden mercedaria y su impronta en Valladolid de Michoacán
Authors: Aguilar Hernández Elsa Anaid
Published: July 2023

El presente estudio aborda el arribo y expansión de la orden de Nuestra Señora de la Merced en la Nueva España, hasta su asentamiento e impronta en la ciudad de Valladolid de Michoacán. El objetivo de este trabajo es presentar los hallazgos sobre esta orden regular masculina que ha sido poco estudiada, se presume, debido a la carencia de información de la misma. Se identifican las fundaciones de la orden mercedaria durante los siglos XVI y XVII, haciendo énfasis en el convento de la ciudad de Valladolid de Michoacán, destaca la identificación de los barrios que conformaban la ciudad en el siglo XVIII, así como algunas propiedades con las que contaba la orden en este periodo.

Estudio de las violencias de género contra mujeres comunicadoras en Cataluña en el marco de la red social Twitter
Authors: Morena Balaguer Diana , Forga Martel Maria
Published: July 2023

Partiendo de un estudio previo sobre la violencia que las mujeres activistas feministas reciben en Twitter, se planteó trasladar esta observación a aquellas que, por su profesión (periodistas, escritoras, influencers…) se ha decidido llamar comunicadoras, ya que convergen en ellas visibilidad pública profesional y presencia y actividad en Twitter. Para observar la relación de estos ataques con cuestiones de género, el estudio se planteó durante la semana anterior y la posterior al Día Internacional de las Mujeres. Entre otros resultados, se observó que 1 de cada 5 tuits originó agresiones y un incremento significativo de violencia durante la jornada del 8M.
Model comparison and effect of flow and accessories on the pressure drop of the unit ff-df-270/el of Universidad de Cartagena
Authors: Gonzalez-Delgado Angel Darío , Villabona-Ortíz Angel , Tejada-Tovar Candelaria
Published: July 2023

The effect of flow variation on the theoretical calculation of pressure drop in pipes with fittings in the unit FF-DF-270/EL of the Universidad de Cartagena was studied, determining the coefficient of minor losses (Kf) caused by 45° and 90° elbows, and three types of valves, using water as the process fluid. The flow rate (Q) was varied, using a valve, between 24, 20, 16, 12 L/min. Darcy's and Bernoulli's theorem methods were used to evaluate friction losses. Were found minimum error percentages of 0.04% and maximum 8.16%; loss coefficients adjusted by minimum squares were obtained with R2 of 0.999, comparing these Kf with the values reported in the plant manual and different authors. It was shown experimentally that the loss coefficient depends on each fitting, allowing the calculation of the theoretical pressure drop and comparing it with the experimental pressure drop, demonstrating that as the flow increases, an increase in pressure drop is generated. With the methodology applied in this research, the aim is to optimize pressure drop tests with fittings, and identify the characteristics of the pipe to obtain an optimum lower loss coefficient value.
Evaluación de secciones compuestas por perfiles de lámina delgada y concreto simple ante cargas de flexión
Authors: Herrera-Laverde German D. , Gil Jhon J. , Duarte Barón Katherin
Published: July 2023

Esta investigación tuvo como objetivo principal evaluar el comportamiento de secciones compuestas de diferentes configuraciones sometidas a flexión, para esto se tuvieron en cuenta los parámetros establecidos por el ANSI/AISC, NSR-10, ACI-18 y pruebas de laboratorio como la prueba de flexión de cuatro puntos. A través de los estudios teóricos se evaluó la rigidez, resistencia y esfuerzos de las secciones para categorizarlas y compararlas entre sí, con secciones de hormigón armado y secciones de acero estructural. Mediante las pruebas de laboratorio se verificó la efectividad del cálculo teórico y el comportamiento real de los materiales. Los resultados de las pruebas demostraron una validación teórica cercana y un comportamiento de flexión dúctil y favorable debido al aislamiento de las partes comprimidas y las partes traccionadas.
Revisión sistemática de las propiedades físico-mecánicas del hormigón con incorporación de Ceniza de Madera
Authors: Muñoz Perez Socrates Pedro , Vallejos Peltroche Debora Gianelly , Pérez Villanueva José Alejandro
Published: July 2023

El presente documento tiene como objetivo realizar una revisión literaria sobre los efectos que produce la utilización de cenizas de madera como componente en el concreto, de tal manera que permita determinar sus propiedades mecánicas y su comportamiento. Se hizo una revisión de 80 artículos arbitrados e indexados en Scopus, Ebsco y Science Direct. Seguidamente, las palabras claves fueron: “concrete and wood ash, replacement of cement with wood ashes, percentages of wood ash in concrete”. A partir de dicha revisión se concluye que la utilización de las cenizas de madera brinda mejores comportamientos físico-mecánicos al momento de ser empleado en materiales como el concreto; sin embargo, sus porcentajes adecuados oscilan entre el 5 al 15% dado que en dichas proporciones ha permitido obtener un incremento en relación del concreto patrón en un 76% de su resistencia a compresión.
