Published: June 2023

Biodegradable foam(biofoam) is a type of bioplastic that is used as an alternative packaging to replace styrofoam which is safe and environmentally friendly. This study aims to determine the characteristics of biofoam made from cassava peel starch (A) and banana peel starch (B), as well as the effect of adding chitosan to the physical, mechanical, and biodegradation properties of the resulting biofoam. In the manufacture of biofoam, the variation of the A:B ratio used is 1:0; 3:2; 1:1 (%w/w). While the chitosan content added was 0%, 15%, and 30% by weight of starch and blowing agent NaHCO3 with a content of 12% by weight of starch. The production of biofoam was carried out using the thermopressing method with a printing temperature of 125°C and a printing time of 7 minutes. The results of biofoam were characterized by density, water absorption, compressive strength, biodegradation, and FTIR functional groups. Based on the research results, it is known that biofoam is close to commercial biofoam standards, namely biofoam with an A:B ratio of 3:2 and the addition of 15% chitosan with a density value of 0.560 g/cm3, the water absorption capacity of 33.68%, compressive strength value of 5, 05 MPa, and the decomposition power of 17.44%. These variations have functional groups N–H, O–H, C–H, C=O, C–N, and C–O.

Published: June 2023

Water loss has become a problem with the balance of a water system, including one in the industry. General opinion has considered evaporation as one of the main justifications for explaining the water loss, especially in the area with a higher daily temperature. A study was conducted on a wastewater treatment system owned by a manufacturing industry consisting of semi-open-air sedimentation and aeration ponds, which suddenly experienced a significant deficit in its water balance. Problem-solving was performed by 8-Step Problem Solving approach and root causes were confirmed by estimating water evaporation. The actual water evaporation rate (E) was approached by pan evaporation (Epan) using the partial pressure of the water vapour and the pan evaporation coefficient (Kpan). The study revealed that evaporation (1.67±0.59mm.d-1 and 1.72±0.62mm.d-1, for sedimentation pond and aeration pond, respectively) was not the main cause of sudden significant water loss  (R2 = .490, p-value .05) and confirmed another root cause. In parallel, a water balance model was constructed and fitted the actual condition (R = .987). A countermeasure was performed against the confirmed root cause followed by a monthly evaluation of water loss using the constructed model with a 3σ threshold value (UCL = 9.55%) which showed the elimination of the problem.

Poetry is a literary work that generally contains expressions of a poet's feelings wrapped in beautiful diction and accompanied by a meaningful style of language. To understand, appreciate, and appreciate a poem specifically, it is necessary to study poetry, of course, by involving a certain approach. One approach that can be used to study poetry is the structuralism approach. Structuralism approach is an approach that emphasizes more on the study of the building elements of the poem itself. In this case, a poem is considered as a unified whole. Furthermore, in this study, the poem that will be analyzed is the poem "Gugur" by W.S. Rendra. W.S. Rendra is an Indonesian poet, playwright, actor and theater director. Since he was young, he has been involved in writing poetry, drama scenarios, short stories, and writing literary essays for various mass media. The research method used is descriptive qualitative using a structural approach. Meanwhile, the purpose of this research is to examine the poem "Gugur" by W.S. Rendra uses a structuralism approach based on the physical elements of poetry and the inner elements of poetry. The physical elements of poetry include diction, rhyme, typography, imagery, concrete words, and language style. Meanwhile, the inner elements of poetry include theme, tone and atmosphere, message, and taste.
Mitigating Taxation Effects on Small Business Enterprises Performance in Kenya
Authors: Mwangangi Richard Isaac
Published: June 2023

For small business enterprise performance to improve, the government needs to reduce taxation or even give tax relief or zero-rate the tax due. In Kenya, national government has taxes levied on all goods manufactured or produced locally and those imported. Kenya Revenue Authority assisted by other government agencies ensure nothing is left untaxed. The local governments are also trying to get their share of tax revenue by ensuring no small business enterprise operates without paying their respective licenses and rates. Cartels are not left behind in their fight for survival by raising their survival funds from the small business enterprises. Small business enterprises are the majority enterprises and the best victim for cartel agencies. Every industry channel their goods and services to customers through the small enterprises. For each industry to survive, it has its charges to those interested in doing business with their products and services. Every small business enterprise will rate its performance through the market share it commands, it’s profit margin over a given period of time against its costs and the many variety goods or services the small business offers. This paper looks at how small business enterprises are mitigating the effect of taxation they find themselves in from the government, cartels and industry to survive.

Published: June 2023

In this paper, we use MHOGA software for the evaluation of adding pumped hydro storage (PHS) for energy arbitrage in utility-scale PV generating systems. PHS is used for electricity price arbitrage, pumping water from the lower reservoir to the upper reservoir with the PV generation during hours of low electricity price and generating electricity by means of the stored water with the turbine during hours of high price (during these hours the PV generator also injects its production to the grid). The control strategy creates setpoints for the use of the pump and the turbine, trying to obtain the maximum benefits from the electricity sold to the grid, maximizing the net present value (NPV). An example of application is shown, obtaining conclusions about the economical viability of the PV-PHS system compared to the PV-only system: in the case studied in this work, it is not worth to add PHS to the PV system.

Published: June 2023

New demand-side management models have emerged as a result of rising energy prices, the development of artificial intelligence, and the rise of prosumers. The purpose of this research is to use deep learning techniques to predict the energy production and demand of a prosumer network to determine dynamic prices for the local market. Gated Recurrent Units (GRU) and Long Short-Term Memory (LSTM) were two methods that were taken into consideration for forecasting consumer demand and wind and solar energy generation. Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE) were used to compare the various approaches. The results demonstrated that GRU, with 0.0273, 0.0158, and 49.8 in RMSE, MAE, and MAPE respectively, is the best method for predicting energy generation and consumption in our datasets. Demand management system dynamic prices were calculated on an hourly basis using input from energy generation and demand forecasts. Finally, an optimization method was developed for establishing the energy planning.

The complexity of a system can be measured according to the number and relationships of the system elements. The design of renewable power plants has grown in complexity in last few decades, due to the integration of new technologies and the application of grid-code requirements. In this paper, a review of MBSE main concepts and leading methodologies (processes, methods, and tools) will be made with the objective of analyzing its application on the renewable power plants modelling and design.
Verification of the uninterrupted transition from grid parallel to island grid operation of the Virtual Synchronous Machine in a microgrid
Authors: Steven Reineke  , Dirk Turschner  , Ines Hauer  , Hans-Peter Beck
Published: June 2023

The classic energy supply system is mainly based on the stabilising properties of electromechanical synchronous generators. The structural change of the electrical energy supply system towards a decentralised grid structure means that ancillary services must now also be provided at the distribution grid level. The Virtual Synchronous Machine (VISMA) was developed at the Institute of Electrical Power Engineering at the Clausthal University of Technology with the aim of making a decentralised generation unit in the grid behave like a real synchronous machine and thus actively provide relevant ancillary services. The VISMA is based on a three-phase inverter that can comply with grid requirements by adding an energy storage device in the DC link and using a special control algorithm. The focus of the investigations shown here is on the uninterrupted transition from grid-parallel operation of the VISMA to island grid operation and the subsequent stable continued operation of this island grid. A controller changeover, as most feed-in inverters would require in order to change the operating mode, is not necessary here. It is shown that the transients have subsided after 5 ms, which means that the VISMA has completely taken over the supply of the load, and the new steady state is reached after 40 ms.
A path planning approach for unmanned solar-powered aerial vehicles
Authors: A. Ailon
Published: June 2023

Solar energy is an available high-quality source for the operation of many technological systems that fulfil the needs of human society. Among all the many applications, the use of solar energy in aircraft is extremely challenging, with a lot of potential advantages. The application of solar energy for flight is one of the promising uses of renewable energy, and in particular the possibility of improving the long endurance requirement in complex missions of unmanned aerial vehicles (UAVs) using solar energy is very attractive. In this context, the article deals with the problem of flight path planning in solar-powered UAVs that fly at a constant altitude. The UAV model incorporates kinematic and dynamic equations where the components of the input vector are the thrust force and the bank angle. Planning the flight path relies here on the flatness property of the system. In fact, his property allows us to plan a flight path without solving non-linear differential equations, and most importantly to link the dynamics of the system, the energy lost and the solar energy absorbed during the flight. Some relevant applications of the approach are discussed, and numerical results are demonstrated.
Modernizing the tradition: Mengaji among children of urban Muslim families in Indonesia
Authors: Rachma Alviani
Published: June 2023

Muslims believe that the Qur’an is the main source of Islamic values, and teaching it to children early is important. The tradition of mengaji, or learning the Qur’an, has been impacted by globalization and modernization. Still, new methods such as online learning and fun-learning techniques have emerged to make the tradition more innovative and creative for children. This article discusses how modernization changes the way of learning activities in reading al-Quran for children (mengaji) in urban areas. Their tradition of going to the TPA/TPQ (Taman Pendidikan Al-Qur’an) shifted to the modern way. It taught Muslims to live alongside digital technology and an internet connection following current conditions. Following the new opportunity to learn Qur’an intensively for children, private Islamic institutions attract some urban muslim families to teach their children Qur’anic reading, such as Binar Qur’an institution. The analysis is conducted by descriptive qualitative research, which is stated by the respondents verbally and in real behavior. The data is obtained through reduction data, explaining data, and drawing a conclusion. Research shows that the impact of modernization forces people to educate their children on Qur’anic reading. It shows that the situation helps the Muslim family to be modern regarding Islamic education. Moreover, the hard struggle of parents to preserve their children in the Islamic path of society is by busying their children with positive activities such as mengaji to fulfill their growth with the Islamic nuance and to produce a better Muslim generation in the future.

There are no recipes or rules to develop games, any more than there are to develop stories. When we try to define a game system that not only has to create a balanced experience, but also has to tell a story, which can engage players in creating empathy and meaning, everything gets complicated. We faced this problem when we had to develop a serious game with the goal of promoting discussion and awareness among children around nutrition: FlavourGame. In this regard, we needed not only to design game mechanics that would feel complete and progressive, but also to create a narrative that provided meaning to the game experience, in order to ensure an underlying layer to the context of nutrition. For that, we had to develop a framework that could help the team in guiding the telling of the story while designing the progression of the game. In this article, we present the full framework as a story-game design approach to be employed in the creation of serious narrative games.

For a long time, Games Research suffered from what Jaakko Stenros and Annika Waern classified as the Digital Fallacy – the tendency to regard analog games as a subset of digital games rather than the other way around. Where boardgames were once associated with the past of games and learning and digital games with the future, there are now fresh insights and applications for boardgames in learning – alongside with their renaissance as games for entertainment. Even as boardgames found new relevance in learning, the already-recognized possibilities in digital games for learning have continued to expand, with more flexible and ubiquitous tools and platforms allowing for a greater variety of avenues of learning research and practice to be explored. Augmented and mixed reality as well as virtual reality are frontiers in learning that beg for further exploration.

"Aim: The aim of the study reported in this paper is to describe the smoking habits of police officers and examine the relationships that can be found between smoking habits, subjective health status, life satisfaction, and happiness. Methodology: The mapping of smoking habits served as a component of a research questionnaire prepared as part of the health promotion activities of police officers. In addition to smoking habits, the respondents had to assess their health (subjective health), life satisfaction, and happiness. Findings: The proportion of smokers in the population studied is as follows: 42.6% have never smoked, 24.9% quit smoking, and 32.4% still smoke. Subjective health status showed a weak but significant association with happiness (p=0.329) and life satisfaction (P=0.343). Value: Special attention should be given to smoking and planning the development of health promotion programs. The poor association of happiness and life satisfaction with subjective health status continues to emphasize mental and psychological health in addition to physical health.

Inmigrantes chinos en tierra de revolucionarios. El caso de Sinaloa
Authors: Cárdenas García Nicolás
Published: June 2023

En este artículo se analiza la experiencia de los inmigrantes chinos asentados en Sinaloa durante las primeras décadas del siglo XX. A pesar de la violencia revolucionaria, lograron cierto éxito económico a la vez que una integración en la sociedad mediante matrimonios, naturalizaciones y la adopción de diversos elementos de la cultura local. Sin embargo, con la Revolución emergió un nacionalismo popular que se expresó en el rechazo a los extranjeros y confirió legitimidad a un movimiento antichino que surgió en las principales ciudades sinaloenses. Sus líderes vincularon al nacionalismo con la defensa de la raza, lo que confirma la tesis de Knight acerca de cómo el culto al mestizo implicaba un racismo invertido. Así surgió un movimiento que en poco tiempo logró sentar las bases institucionales y simbólicas que permitirían, años después, expulsar a los chinos del estado.

El presente artículo propone un estudio de los tripulantes de las embarcaciones españolas en el siglo XVII, marineros, pajes, grumetes, artilleros y pilotos, para reflejar el proceso de la llamada “globalización temprana”. El propósito consiste en examinar su papel como intermediarios entre mundos distantes y la conciencia que pudieron tener de esta primera globalización. Se esboza, primero, un retrato de la gente de mar para intentar definir los contornos de sus vidas globales. Se analiza, seguidamente, la vida material de los tripulantes para destacar las características de un mundo que empezaba a globalizarse. Para terminar, se estudian las actitudes ante la muerte de estos tripulantes para revelar en qué medida sus vidas y sus devociones religiosas reflejaron dicha conciencia.
¿Dónde estaba su hogar? Un migrante checo en México, en medio de la Revolución y la Guerra Fría
Authors: Křížová Markéta
Published: June 2023

Gracias a la modernización del transporte, tanto marítimo como terrestre, que permitía travesías más cortas, rápidas y seguras, hacia finales del siglo XIX se diversificó considerablemente el mercado de trabajo en el espacio atlántico y empezaron a entrar en este mercado también los habitantes de regiones que históricamente carecían de acceso al mar. Tal fue el caso de los obreros migrantes de los países checos, unidad geográfica ubicada en el centro del continente europeo, compuesta por las regiones históricas de Bohemia, Moravia y Silesia, que hasta 1526 habían estado bajo el reinado soberano de los reyes de Bohemia. Entre 1526 y 1918 formaban parte del Imperio de los Habsburgo. En 1918, se unieron con Eslovaquia y Rutenia (hasta entonces partes del reino de Hungría, también bajo del gobierno Habsburgo), fundándose así el nuevo Estado de Checoslovaquia. Algunos checos se habían instalado en América desde el siglo XVI, pero no fue sino hasta finales del XIX cuando comenzó una gran oleada de los que buscaban trabajo, tierras, a veces libertad política o conocimientos y aventura.

Typology of terrain vague and emergence mechanisms in post-communist, post-industrial small and medium-sized towns in Slovakia: Case study of Humenné, Strážske and Vranov and Topľou
Authors: Hajduková Romana , Sopirová Alžbeta
Published: June 2023

There have been many problems associated with underutilized areas in towns, although they also offer significant potential for urban renewal, especially in post-communist, post-socialist countries, where a series of key historical events has caused socio-economic and political changes leading to urban decay. The underlying feature of unused areas is their apparent abandonment, absence of use, lack of identity but high potential. However, not all unused areas should be labelled as brownfields; therefore, we studied the terms commonly used to describe underutilized areas. We chose the term terrain vague to map and describe all apparently empty but still intriguing spaces in our model towns of Humenné, Strážske and Vranov and Topľou, in eastern Slovakia. Our paper aims to create a typology of terrain vague to better understand its manifestation in our conditions. It also aims to determine the causes that led to its emergence or as we call it the emergence mechanisms, in the context of post-industrial small and middle-sized towns in Slovakia. We combined field survey and desktop analysis methods to map terrain vague based on set criteria. We evaluated mapped terrain vague and, using the data, created a typology of terrain vague consisting of nine types and identified three key emergence mechanisms and their subcategories. We based them on commonly used terms that fit within the specific context of our model towns. By using the new typology and emergence mechanism, we can identify patterns running along towns with similar backgrounds that result in similar problems and develop solutions accordingly. Results of our research could be generalized and serve as a basis for future research aimed at finding strategies for revitalizing terrain vague in shrinking post-industrial towns facing different problems than prosperous cities.
Balance of Payments as a Monetary Phenomenon: An ARDL Bounds Test Method for Algeria
Authors: Ghilous Azeddine , Ziat Adel
Published: June 2023

Research background

Every country attempts to improve its balance of payments (BOP) position to enhance macroeconomic policy. Algeria, like many developing countries, is experiencing a BOP deficit. This raises concerns about the reasons for this deficit and prioritizes the quest for potential answers.

Purpose

In the context of the Monetary Approach to the balance of payments (MABP), this paper investigates the long-run relationship between domestic credit, inflation, interest rate, GDP, and net foreign assets to find whether BOP is a monetary phenomenon in Algeria from 1980 to 2019.

Research methodology:

The Autoregressive Distributed Lag (ARDL) bounds test, combined with the critical approximation p-values of Kripfganz and Schneider (2020), has been applied.

Results

The findings clearly showed a long-run relationship among the variables. The long-run estimates strongly supported MABP propositions, and domestic credit had a negative and statistically significant influence on net foreign assets. This suggests that Algeria’s BOP is a monetary phenomenon, and excess money supply played a crucial role in Algeria’s balance of payments disequilibrium.

Novelty

The contribution of this paper is the use of the ARDL bounds test in combination with the novel critical approximation p-values of Kripfganz and Schneider (2020), which provided more robust results. This study could help monetary authorities to elaborate the suitable policies in dealing with BOP problems in Algeria.
Sales Revenues and Corporate Sustainability Performance: an Efficiency Analysis of the 20 Top Companies Listed on the Warsaw Stock Exchange
Authors: Matuszewska-Pierzynka Agnieszka
Published: June 2023

Research background

Generally, corporate sustainability studies focus on identifying the relationship between corporate sustainability performance and corporate financial performance among different companies without measuring the company’s efficiency based on sustainability pillar scores.

Purpose

The essential aim of this paper is to explain the differentiation of business efficiency in terms of corporate sustainability performance by answering the question of how sustainability pillar scores influence the relative efficiency of a company?

Research methodology

The empirical studies were conducted among the 20 top companies listed on the WSE for the period of 2019–2021 with the use of the Data Envelopment Analysis (DEA) and the Spearman’s rank correlation coefficient.

Results

The research hypothesis, which states that more efficient companies are characterized by a higher level of sustainability in all its particular dimensions, cannot be positively verified, because a positive and statistically significant correlation dependence between the average efficiency measure and average sustainability pillar scores existed only for the governance dimension.

Novelty

The estimation of efficiency measure based on corporate sustainability performance has included not only environmental, social and governance dimensions, but also the economic one, which was represented by the long-term returns pillar score.

From the findings of the study the positive influence of various Reward Systems, Trend towards Participation and Trust was observed on the development of human capital. However, the results of the study showed no significant influence of the dimensions of information systems on the development of human capital.

Novelty

There are no previous studies which have substantiated the positive impacts of Organizational Culture on Human Capital Development (HCD) which were explicit to the Indian healthcare service sector. Furthermore, the findings of this study provide a unique insight into the influences of certain elements of organizational culture upon developing the human capital of healthcare service sector employees in the Indian context.
Diversification of agricultural activity in the territorial breakdown of Lubuskie Province
Authors: Szczuciński Przemysław
Published: June 2023

Research background

Each type of administrative unit, including cities, towns and villages, plays a different role in the regional economy. In the case of rural areas, their most important function is agricultural production.

Purpose

This paper offers a contribution to the discussion on the review of the agricultural development strategy for Lubuskie Province. It attempts to present selected characteristics of the agricultural sector in a cross-section of municipalities of Lubuskie Province against the background of the general features of the agricultural sector in the region. Its purpose is to draw the attention of regional authorities and institutions to the heterogeneity of agricultural development within its territory.

Research methodology

The research was conducted using a principal component analysis as one of the methods of the graphical presentation of multivariate data. Data from the National Agricultural Census 2020 was used in the analysis.

Results

The results of the research corroborate the hypothesis of the existence of significant differences in the agricultural sector in the area of the examined rural and urban-rural municipalities in the region, and the need for differentiation of the measures used by the regional authorities to support agriculture in its territorial cross-section.

Novelty

The paper presents the results of a research on the heterogeneity of the development of the agricultural sector in the municipalities of the examined region. Such an analysis has never before been carried out for the province under consideration.
Dendrimers as Antimicrobial Agents in the Central Nervous System Infections. A Review
Authors: Kucková Katarína , Bhide Mangesh
Published: June 2023

Bacterial meningitis is a serious infection of the central nervous system that affects people all over the world.Streptococcus pneumoniaeandNeisseria meningitidisare the most common pathogens causing meningeal inflammation in Europe. Treatment with standard antibiotics is becoming ineffective, not only due to their inability to cross the blood-brain barrier, but also due to rising antibiotic resistance. As a result, novel therapeutics to combat the infection are required. A promising solution could be therapeutic nanomolecules, such as dendrimers, some of which have antimicrobial properties due to their chemical structure. Additionally, they may be decorated with a suitable therapeutic and central nervous system homing peptides to construct nano-drug delivery systems, which can effectively cross the blood-brain barrier. To synthesize safe dendrimeric nano-drug delivery system it is necessary to select the best dendrimer candidates with antimicrobial activity and to understand pharmacosafety, pharmacokinetics and dynamics. This review provides a brief overview of dendrimers and their antimicrobial properties as they have been studied in relation to the blood-brain barrier and existing antibiotics.

This present study aims to investigate the relationship of herd characteristics and management practices with the prevalence of clinical and severe lameness, hock and knee injuries, thin cows, and mastitis at the herd level on Algerian dairy farms. Altogether 1210 dairy cows from 107 farms were examined and the clinical aspects related to studied affections were recorded. Multivariable regression models were built to analyse the relationship between the risk factors and the occurrence of health indicators. Overlay, the health outcomes were multifactorial, with pasture access (P < 0.001), scraping frequency (P < 0.01), and floor regularity (P = 0.05) as the main factors causing lameness. Factors associated with both hock and knee injuries (score ≥ 2) were lower cow number (P < 0.01), more days spent on pasture (P < 0.001), and poorer straw amount for bedding (P < 0.001). Some farming practice, in particular, providing proper amount of concentrate feeds (P < 0.001), higher scraping frequency (P < 0.01), thicker bedding (P < 0.001), and having younger dairy cows (P = 0.058), were associated with a lower within-herd prevalence of thin cows. While, more days on pasture increased the percentage of under-conditioned cows (P < 0.01). The inadequate hygienic conditions of the floor (P < 0.001), improper milking procedures (P < 0.05), and shorter dry period (P < 0.05) increased the clinical mastitis occurrence. Our results highlighted the specific management practices responsible for increasing health risks and provided useful information for the farmers and veterinarians to make preventive and controlling strategies for lameness, leg injuries, low body condition and mastitis on dairy farms.

Tick-borne Spotted Fever Group Rickettsioses (SFGR) is a serious disease reported in low income communities of many developed countries. The dearth of information on the existence of SFGR in most developing countries particularly in Sub Saharan Africa (SSA) including Nigeria, has been attributed to many factors chiefly amongst which are; poor knowledge of the disease, limitation of diagnostic capacity, leading to misdiagnosis and under reporting of some infectious zoonotic diseases such as SFGR. The aim of this study was to evaluate the pastoralists (livestock farmers) and animal health workers’ knowledge, attitudes and perceptions/practices towards ticks and tick-borne SFGR affecting livestock in 3 Local Government Areas (LGA): i.e., in Plateau State, Nigeria and including Jos the Capital City of the State. A total of 141 semi-structured questionnaires were administered to respondents including 90 pastoralists and 51 health workers from different veterinary clinics. Interestingly, the pastoralists expressed no knowledge about SFGR, although 61.36 % reported a history of tick infestation. Among the animal health workers, about 76.47 % expressed some knowledge about the disease, but lacked knowledge of the diagnosis of the disease. The findings indicate that there was the need for an increase awareness on SFGR and its predisposing factors among relevant stakeholders in the Plateau State, Nigeria.

Flooding may occur due to dam failure at downstream of the spillway. Stilling basin of the spillway plays an important role in reducing turbulence generated by hydraulic jumps. It can avoid flooding and local scouring as well. Therefore, this study aims to analyze hydraulic jump characteristics experimentally. Two series of structures namely initial (S0) and final (S1) were tested. The S0 model is the United States Bureau of Reclamation (USBR) III type, while S1 is set the adverse slope of 1:2 at the downstream and lowering the bottom elevation of the channel by 4 m. Measurements were taken on the length of hydraulic jumps, water level and high speed before-after hydraulic jumps at various return periods discharges (Q) of 2, 5, 10, 25, 50, 100 and 1000 years. It is found that at S1, the jump is submerged, causing the relative hydraulic jump height (y2-y1)/y1 to be 40-90% higher than S0. Furthermore, the compression of more than 50% of the hydraulic jump length ratio (Lj/y2) was indicated at S1. In addition, the energy dissipation efficiency (εt) obtained for each discharge at S1 ranged from 58-84% (good absorption). On the other hand, at S0, the εt produced was around 70-89% (Q2-Q50) and 45% (Q100 and Q1000). It can be concluded that the modification of USBR III can reduce the vulnerability of the bottom and downstream parts of the stilling basin. It is expected that the potential flood disaster due to the stilling basin failure of the dam can be eliminated. These results may be used as recommendation to the disaster management strategies, such as improving dam safety guidelines, informing emergency response plans, or guiding infrastructure design to withstand hydraulic forces.
Las consecuencias hídricas del decreto de dotación ejidal para los comcáac de Punta Chueca, Sonora (1970-2021)

Published: June 2023

Objetivo: mostrar las consecuencias hídricas del decreto presidencial de dotación ejidal en 1970 que creó, políticamente Desemboque y su anexo Punta Chueca y, a la vez, estableció definitivamente a los comcáac en el territorio que ocupan actualmente. Metodología: recopilación documental, el análisis conceptual de “lucha”, revisión de hemerografía, aplicación de entrevistas a autoridades tradicionales y pobladores comcáac y recorridos de campo realizados en el periodo 2018- 2021. Resultados: muestran una serie de problemáticas relacionadas con la disminución del territorio ancestral seri, los vínculos con los antiguos accesos al agua y la presencia de luchas por el agua. Limitaciones: falta de testimonios de pobladores comcáac que participaron directamente en el proceso legal de la dotación ejidal de 1970, ya que ello enriquecería la comprensión de ese complejo proceso histórico-jurídico del pueblo seri. Conclusiones: la dotación territorial de 1970 originó dos etapas de construcción social de escasez de agua, una institucionalizada, que repercutiría en el inicio de luchas por nuevos accesos de agua a mediados de 1990 e incrementarían en grado de violencia en la segunda etapa de escasez que llamamos “moderna” representada en los distintos proyectos desaladores de 1999, 2003, 2008 y 2014. Finalmente, la sobrenaturalidad que aportaban los antiguos accesos al agua se fue perdiendo y olvidando por las generaciones nacidas después de 1970.
