Published: April 2024

Mucormycosis (zygomycosis) is a globally invasive fungal infection that rarely occurs in immunocompetent but frequently in immunocompromised patients and is associated with high morbidity and mortality. The biopsy is the preferred method of diagnosis but may not be an option in the early course of the disease, resulting in delayed diagnosis and increased mortality. Herein, we presented a case of disseminated rhino­orbital-cerebral mucormycosis (ROCM) in mixed phenotype acute leukemia (MPAL) with Philadelphia (ph) chromosome positive and shared the therapy to it.

Published: April 2024

Ho:YAG laser lithotripsy is a widely used technique for treating urinary stones, but concerns persist regarding its thermal effects on renal tissues. This study aimed to monitor intrarenal temperature changes during kidney stone treatment using retrograde intrarenal surgery with Ho:YAG laser. Fifteen patients were enrolled. Various laser power settings (0.8 J/10 Hz, 1.2 J/12 Hz) and irrigation modes (10 cc/min, 15 cc/min, 20 cc/min, gravity irrigation, and manual pump irrigation) were used. Temperature changes were recorded with a T-type thermal probe with ± 0.1°C accuracy. The laser power had the most significant effect on the mean temperature, with the mean temperature being 4.981°C higher for the 14 W laser power than for the 8 W laser power (p < 0.001). The mean temperature was 2.075°C higher in the gravity irrigation model and 2.828°C lower in the manual pump irrigation model (p = 0.038 and p = 0.005, respectively). Body mass index, laser power, irrigation model and operator duty cycle explained approximately 49.5% of the mean temperature (Adj. R2 = 0.495). Results revealed that laser power and operator duty cycle positively impacted mean temperature, suggesting that higher settings and longer activation periods led to increased temperature. Conversely, increases in body mass index and utilization of certain irrigation models were associated with decreased mean temperature. Laser power and irrigation rate are critical determinants of intrarenal temperature during Ho:YAG laser lithotripsy. Optimal settings and irrigation strategies are essential for minimizing thermal injury risk. This study highlights the importance of ongoing research to better understand and mitigate thermal effects during laser lithotripsy.

Published: April 2024

The understanding of public health condition is important for the community resilience. The evaluation of public health resilience provides crucial information for urban planning. To estimate the susceptibility and recuperability of epidemic, the urban anti-epidemic resilience indicator system which consists of three categories of risk, repression, and adaptability is constructed by models which are established to estimate the mobility and concentration of population and the accessibility of medical resources. After collecting and reprocessing data with Geographic Information System (GIS) of 30 cities of China, through Weighing-TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), resilience level of objects is obtained. Results show an overall anti-epidemic resilience situation is controlled by population mobility, population aggregation, health resource, governance, and socioeconomics, which could assist in urban design and pandemic response.

Authors: Echeverry Jhon M. Escobar , Valero Juan J. , Alfonso Natalia Guzmán , Fierro Fernando , Molina Iván D.
Published: April 2024

PURPOSE
To categorize appendix location with a modified classification and describe the outcomes associated to each location.
METHODS
Prospective observational cohort study of children who underwent laparoscopic appendectomy in a reference children’s hospital; the diagnosis of acute appendicitis (AA) was confirmed by the pathology department and clinical history data were taken. The location of the appendix was classified as retrocecal (RA), pelvic (PEA), right Iliac fossa (RIF) and an intraoperative photograph was taken for confirmation.
RESULTS
The location of the appendix was divided in three groups (RIF 42%, PEA 33%, RA 25%). Significant differences were found in time of symptom onset (RA > 48 hours in 54.5% of patients p: 0.001) and in the ultrasound diagnosis of appendicitis (RIF 49.3%, RA 25.9%, PEA 24.6% p: 0.01). The primary outcome assessed was appendix perforation, also with significant differences between appendix locations (average 37.8%, PEA 46% p: 0.001).
CONCLUSION
The classification of the location of the appendix in RIF, PEA and RA is clear, simple, and reproducible, being RIF the most frequent location. The pelvic localization was associated with the presence of perforation, possibly because signs of peritoneal irritation are less common in these children, and it was less visualized on ultrasound.
Paediatric cervicofacial lymphadenitis caused by non-tuberculous mycobacteria: nation- wide overview in the period 2000-2020
Authors: Sodja Eva , Šivic Urška , Truden Sara , Klemen Špela , Žolnir-Dovč Manca
Published: April 2024

Purpose
Cervicofacial lymphadenitis caused by non-tuberculous mycobacteria (NTM) is a rare but increasing infection in children worldwide. The purpose of this study was to analyse and evaluate all microbiologically proven cases of NTM lymphadenitis in children under the age 14 years and to discuss possible reasons why there is no Mycobacterium haemophilum isolates among cases of paediatric NTM lymphadenitis in Slovenia.
Methods
Between 2000 and 2020, we retrospectively reviewed laboratory and medical records for some basic demographic and microbiological data. Different clinical samples were collected in medical centres and regional hospitals from all over Slovenia.
Results
In the period before mandatory BCG vaccination was discontinued (2000–2005), we did not observe any case of paediatric NTM lymphadenitis. After discontinuation of non-selective BCG vaccination of new-borns (2006–2020), we identified 55 cases of microbiologically confirmed NTM lymphadenitis in BCG-unvaccinated children with median age 26.0 months (range: 15.0–75.0 months). Mean annual incidence of paediatric NTM lymphadenitis accounted for 1.26 (range: 0.35–2.38) per 100,000 children. The main causative agents were Mycobacterium avium (38/55; 69.1%) and M. intracellulare (9/55; 16.4%). We did not find any M. haemophilum isolate. Since 2006, each year we microbiologically confirm sporadic cases of paediatric NTM lymphadenitis, a condition not diagnosed before.
Conclusions
Strong evidence suggests that the main reason for that is discontinuation of universal BCG vaccination in March 2005. Nevertheless, we could not neglect the effect of improved diagnostic procedures used in recognizing NTM as causative agents of paediatric lymphadenitis.

Published: April 2024

This study explores microgrid scheduling for drilling operations using hybrid energy, with a focus on managing an energy storage system (ESS) and utilizing a diesel generator for backup. The optimization process encompasses backup from the diesel generator, renewable energy integration, energy storage utilization, and network load management involving various equipment. MATLAB software was employed for simulation and analysis. The research underscores the significance of energy storage in managing peak workloads, devising backup generator schedules, and regulating loads to explore potential economic advantages like fuel savings through hybrid energy and battery storage supported by the diesel generator. It assesses production power, cost savings, pollution mitigation, and enhancement of power quality. The test duration spans approximately one working month of the drilling machine at 24-hour intervals and extends to cover the entire drilling operation period. The proposed ESS system for a land rig is projected to slash CO2 emissions by roughly 5000 tons throughout its operational lifespan. Furthermore, it indicates a potential 22% decrease in fuel energy consumption compared to current plant management practices.
Novel precise separation technology will significantly improve the circulation of critical metals in automotive lithium-ion batteries
Authors: Dou Yi , Heiho Aya , Tokoro Chiharu , Kikuchi Yasunori
Published: April 2024

Recently, large-scale projects using pyro/hydrometallurgy have been introduced worldwide for recycling spent automotive lithium-ion batteries (LIBs), while a few precise separation methods are under development to support a faster, complete, eco extraction of positive electrode active materials. However, the extent to which the precise separation impacts the whole recycling system and the requirement for co-ordinated policy and system design remains poorly understood. Here, we develop an integrated assessment model with technical and policy scenarios that applies a novel precise separation method named high-voltage pulsed discharge to the emerging Japanese electric vehicles market during 2025–2050. We show that the precise separation can be a must-have process that may significantly reduce the life-cycle greenhouse gas emissions, the resource consumption potential and the in-use stocks of critical metals (Li, Ni, Co, Mn) compared with the conventional technology combination. To achieve this condition, combined efforts from technology development, system integration, secondary usage regulation and eco-design in LIBs are required.
Forecasting Exchange Rate Depending On The Data Volatility: A Comparison Of Deep Learning Techniques
Authors: Sönmez Filiz Erataş , Birim Şule Öztürk
Published: April 2024

The prediction of the foreign exchange rate is critical for decision makers since international trade is a vital task, and an accurate prediction enables effective planning of the future. To model the exchange rate behavior over time, a deep learning methodology is used in this study. Deep learning techniques can uncover indeterminate complex structures in a dataset with multiple processing layers. Traditional artificial neural networks (ANNs) do not consider the time dependence between data points in time series data. To overcome this problem, deep learning tools, such as recurrent neural networks (RNNs), consider long-term time dependency in the data. In this study, among the types of RNNs, long short-term memory (LSTM), bidirectional LSTM, and gated recurrent units (GRUs) are used to predict time series data of USD/TRY and EUR/TRY. This prediction is conducted for three different periods in the last 11 years in Turkey. One period includes near-steady data, and two periods have volatile exchange rate data. The prediction performance of the models is evaluated based on the mean absolute error (MAE), root square error (RMSE), and mean absolute percentage error (MAPE) metrics. After the comparison of different models, the bi-LSTM and GRU models are found to yield the most accurate predictions in volatile periods, depending on the nature of the volatility. This study proposes new models for exchange rate estimation and compares the performance of each model based on the volatility of the data.

Published: April 2024

The research was conducted to identify the present status of the food safety knowledge, attitude and practices of meat handlers in retail meat shops of Khulna City, Bangladesh. The research was performed through face-to-face interviews of randomly selected 65 meat handlers in six areas of Khulna City. Socio-demographic information of all respondents was collected. The illiteracy rate was 15.38%, while the majority (42.9%) of the respondents had secondary education. The highest proportion (43.07%) of meat handlers was low experienced in meat handling. Among the respondents, 58.46% were sellers, while no respondents had any training on butchery and food safety. All respondents worked at least three days a week and meat handling was the main occupation for all respondents. Most of the respondents (50.76%) had low media contact. The highest proportion (74.3%) of the respondents had medium (scores of 11 to 20) food safety knowledge. About 62.9% of the respondents had moderately favorable food safety attitude (scores of 28 to 54), while 60.0% of the respondents had medium food safety practices (scores of 15 to 28). The mean score of the food safety knowledge, attitude and practices was 18.65±3.81, 50.71±9.49 and 27.20±3.22, respectively. This study shows that there is an identified gap in knowledge and correct practices among meat handlers and that there is a need to raise awareness about food safety through education programs regarding food safety and safe food handling practices. These findings can help public health professionals in developing initiatives to improve food safety knowledge and practices of meat handlers and prevent foodborne diseases (FBDs). The government should pay special attention for improving knowledge and ensuring proper food safety practices to avoid the transmission of FBDs in Khulna City.
Heat and charge transport in interacting nanoconductors driven by time-modulated temperatures
Authors: López Rosa , Simon Pascal , Lee Minchul
Published: April 2024

We investigate the quantum transport of the heat and the charge through a quantum dot coupled to fermionic contacts under the influence of time modulation of temperatures. We derive, within the nonequilibrium Keldysh Green’s function formalism, generic formulas for the charge and heat currents by extending the concept of gravitational field introduced by Luttinger to the dynamically driven system and by identifying the correct form of dynamical contact energy. In linear response regime our formalism is validated from satisfying the Onsager reciprocity relations and demonstrates its utility to reveal nontrivial dynamical effects of the Coulomb interaction on charge and energy relaxations.
Inferring effective couplings with restricted Boltzmann machines
Authors: Decelle Aurélien , Furtlehner Cyril , Navas Gómez Alfonso de Jesús , Seoane Beatriz
Published: April 2024

Generative models offer a direct way of modeling complex data. Energy-based models attempt to encode the statistical correlations observed in the data at the level of the Boltzmann weight associated with an energy function in the form of a neural network. We address here the challenge of understanding the physical interpretation of such models. In this study, we propose a simple solution by implementing a direct mapping between the Restricted Boltzmann Machine and an effective Ising spin Hamiltonian. This mapping includes interactions of all possible orders, going beyond the conventional pairwise interactions typically considered in the inverse Ising (or Boltzmann Machine) approach, and allowing the description of complex datasets. Earlier works attempted to achieve this goal, but the proposed mappings were inaccurate for inference applications, did not properly treat the complexity of the problem, or did not provide precise prescriptions for practical application. To validate our method, we performed several controlled inverse numerical experiments in which we trained the RBMs using equilibrium samples of predefined models with local external fields, 2-body and 3-body interactions in different sparse topologies. The results demonstrate the effectiveness of our proposed approach in learning the correct interaction network and pave the way for its application in modeling interesting binary variable datasets. We also evaluate the quality of the inferred model based on different training methods.
Stochastic series expansion quantum Monte Carlo for Rydberg arrays
Authors: Merali Ejaaz , De Vlugt Isaac J. S. , Melko Roger G.
Published: April 2024

Arrays of Rydberg atoms are a powerful platform to realize strongly-interacting quantum many-body systems. A common Rydberg Hamiltonian is free of the sign problem, meaning that its equilibrium properties are amenable to efficient simulation by quantum Monte Carlo (QMC). In this paper, we develop a Stochastic Series Expansion QMC algorithm for Rydberg atoms interacting on arbitrary lattices. We describe a cluster update that allows for the efficient sampling and calculation of physical observables for typical experimental parameters, and show that the algorithm can reproduce experimental results on large Rydberg arrays in one and two dimensions.

CASE STUDY OF ISRAEL-PALESTINE CONFLICT AND THE ABUSE OF HUMAN RIGHTS
Authors: Bandyopadhyay Lahari
Published: April 2024

Israel is an established country. And Palestine, despite being a country with rich heritage since ages, has been occupied by the Israel government who refuse to provide Palestine with the status of a sovereign nation. Israeli-Palestine conflict has led to numerous war crimes and most of the victims have always been the innocent and common people of the land. Besides territorial disputes, religious fundamentalism and persecution has also been a major factor. The state of Israel has always supported the ideology of Zionism wherein Israel supported the establishment of a Jewish state. Jews also claim that there is a large-scale antisemitism among the Arabs as well as various other communities because of which they face non-acceptance. But the conflict is not merely confined to one cause and has other grounds as well. This paper takes up the study of the conflict between the two countries and analyse the historical and political background that led to the series of events and how it led to the abuse of human rights in the region. The research further seeks to find out the role of the USA and the United Nations. USA had been the pioneer of liberalism and human rights in todays neo liberal world, but has remained silent in occasions of Israels wrongful claims over Palestinian territories. Hence, the protection and restoration of humanitarian laws is a major field of discussion.

Published: April 2024

The research aimed to elaborate the myths following traditions in explicit connection with the Kajang indigenous people's dwellings and way of life. The existence of Kajang indigenous people was known for preserving their traditions with austerity. Clinging to their traditional belief system, Pasang ri Kajang was used to protect their sacred forest and natural environment. Some myths still seemed relevant and took part actively in their everyday lives. This was an empirical qualitative research, with the researcher directly visiting the location to experience the cultural situation and the people of Kajang. First-hand experience, photographing, hand sketching, interviews, and focus group discussions were employed to collect data. Analyzing the characteristics of the Kajang area from the maps, narrative analysis for the interview, focus group discussion, sketches, manual notes, photographs, and cross-analysis from literature studies resulted in the difference between inner and outer Kajang. It is found that eight practical conducts closely related to the myths are elaborated, such as oral communication, no electricity, no clay roof tile, no footwear, no colorful clothes, no decoration or modern material, orientation of buildings, and odd numbering and time calculation. Some limitations and suggestions are also presented.

The research aimed to investigate the tourism villages provided by indigenous people in Indonesia to create a sense of place for visitors. Indigenous communities in Indonesia were often faced with discrimination and negative stigma. However, by utilizing the potential of their cultural heritage and local resources, they created a sense of place in their tourist village. The primary objective was to understand the role of indigenous entrepreneurs in preserving tourism villages and identifying the challenges faced. The research applied a qualitative approach with a case study method and was conducted in several locations, including Pampang-Kalimantan, Sade-Lombok, and Kampung Ulos-Sumatera, representing various instances of indigenous entrepreneurs managing tourism villages. The analysis focused on the characteristics of indigenous entrepreneurship and the challenges faced. Furthermore, the data were obtained through interviews and documentation with community leaders, business actors, and key figures providing assistance to indigenous entrepreneurs. The results show that indigenous entrepreneurs play a crucial role in preserving a sense of place in the respective tourism villages. These characteristics influence the physical, social, and shared meanings constituting a sense of place. However, the entrepreneurs face various challenges in the preservation efforts, including issues related to costs, management of traditional spaces for homestays and guest houses, financial support and administration, limited management and tourism-supporting facilities, enhancing storytelling, and sustainable tourism packaging for area marketing.

The research aimed to describe the urgency of family visits as an implementation of maintaining human dignity in social life. Currently, violence in the family has become widespread and even increased over time, and the victims of violence are generally women and children who are completely helpless. The method applied was a literature review from various sources, namely indexed journals and books with a good impact factor. Literature reviews were collected, selected, and analyzed by identifying relevant topics, recording and reviewing concepts found from various sources, and systematically compiling the results of literature reviews. The results found are that family visits have three values that can be applied to maintain human dignity: building brotherhood as social creatures in society, listening to each other, and applying security principles to maintain collective integrity and security within the family. In conclusion, family visits are very important and needed by today's society because families need to greet each other, listen, and protect each other from crime. This effort is made so that human dignity in the image of God is maintained. Advice for Christian families is that carrying out family visits at this time is very important as a form of implementation of maintaining human dignity, which is starting to be shifted due to developments in science and technology in society.
Traditional Wayang Research Productivity: A Bibliometric Analysis
Authors: Purbasari Mita , Carollina Donna
Published: April 2024

The aim of the research was to review the productivity of Wayang’s research by using the bibliometric method from the Scopus database. Wayang is a form of traditional art recognized by UNESCO as a Masterpiece of the Oral and Intangible Heritage of Humanity since 2003. It was not obtained easily, especially in terms of the world community’s introduction of shadow puppets. Puppet research has exploded since it was recognized by UNESCO. However, global indexed publications still needed to be enhanced. Analysis of Wayang research from internationally indexed journals, such as Scopus, was required to recognize this opportunity; the object could be seen from a different perspective. The dataset used was ‘Traditional Wayang’, based on documents during 2015-2021 from the Arts and Humanities areas. The search has found 36 papers related to ‘Traditional Wayang’ research. The number of Wayang studies in Scopus-indexed papers remains limited, retaining the Wayang perspective as a traditional object. This is shown by the 36 documents examined, among which only two clusters are produced: performance and change. In order for Wayang research to have great potential and be considered from a wide range of perspectives, including technological, social, economic, commercial, and other, there are still other types of Wayang as an object material.

The cultivation of the sea cucumber Holothuria scabra Jaeger for broodstock and production in captivity at sea with naturally available feed, it was reported that the daily growth rate was slow at 0.14±0.10g day-1 (Jasmadi, 2018).  One of the efforts to increase growth is substrate manipulation. Organic material in the form of chicken manure has been applied in this study as a mixed substrate with sand at different percentages. Holothuria scabra  This study aims to manipulate  Holothuria scabra rearing substrates to increase growth.  This study used a completely randomized design (CRD) at a 95% confidence level. The research treatments consisted of treatment A (10% organic matter 80% sand), treatment B (20% organic matter 80% sand), treatment C (30% organic matter) 90% sand), D (without organic matter = 100% sand) (100% sand), each treatment was repeated three times. The results showed that the availability of organic matter in the form of chicken manure at different percentages in the sand substrate had a significant effect on growth (P<0.05), but was not significantly different on the survival rate of Holothuria scabra. The growth of  Holothuria scabra were better when organic matter is added than without organic matter content in the form of chicken manure.  The difference in the percentage of organic matter affects the fulfillment of energy for nutritional needs, so that the availability of energy for growth is also different, but this difference does not affect Holothuria scabra’ survival rate. The difference in the percentage of organic matter content in the form of less or excess chicken manure has been shown to have a negative effect on growth.  Furthermore, it is known that treatment B (20% organic matter in the form of chicken manure and 80% sand) per substrate weight has a better effect on growth compared to other treatments.  treatment B (20% organic matter in the form of chicken manure and 80% sand) per weight of substrate can be applied to increase growth Holothuria scabra in rearing substrate manipulation.  it is recommended that further research be conducted on the period of addition of organic matter, because there are indications of a decrease in organic matter content during the study.

The best feed ratios were compared to improve the performance growth of Arowana. The research was conducted in October - November 2022 at the ornamental fish farm named Badai Arwana Tasikmalaya, West Java. This research used an experimental method with a completely randomized design through five treatments and four repetitions. The treatments consisted of (A) guppy fish as the control feed (100%); (B) local cricket as the tested feed (100%); (C) Dubia roach as the tested feed (100%), (D) combination of guppy fish (50%) with local cricket (50%); and (E) combination of guppy fish (50%) with Dubia roach (50%). The treatments were given for 40 days, and the growth parameters of those Arowana seeds were then observed every 10 days. The observed parameters covered Survival Rate (SR), Absolute Length Growth (L), Absolute Weight Growth (W), Feed Conversion ratio (FCR), and Water Quality. SR, W, L, and FCR data were analyzed using ANOVA with a significant level of 95% and if there is a significant difference, the Duncan test will be further conducted. Meanwhile, water quality was descriptively analyzed.

The research results showed that the feed combination of guppy fish (50%) with local cricket (50%) could improve the SR and growth performance of Arowana seeds. The given feed combination with the ratio of guppy fish (50%) with local cricket (50%) resulted in SR (100%), L (9.07 cm), W (10.53 g), and FCR (2.36). Meanwhile, the water quality during the research was in appropriate and stable conditions.

Published: April 2024

A new composite material with magnetic and pH-responsive properties, composed of chitosan/ poly(2-diisopropylamino)ethyl methacrylate (Fe3O4/SiO2/CS/PDPA) was developed with the purpose of removing avermectins in aqueous media. The material was characterized by different techniques to evaluate its characteristics. The adsorption process was investigated through the optimization of some parameters, with the most favorable results at pH 8.0, using 20 mg of adsorbent and stirring for 5 min. Under such conditions, the material showed adsorption efficiency of around 80.5, 69.9, and 74.8% for eprinomectin, doramectin and ivermectin, respectively. The adsorption mechanism was investigated using the pseudo-second order kinetic model and the Langmuir-Freundlich dual site isotherm model. Thermodynamic analysis indicated that the adsorption process is exothermic and spontaneous. The material also showed good regenerative capacity, allowing several reuse cycles. The results obtained suggest that the synthesized material has potential application as an adsorbent in the removal of avermectins from aqueous samples.
History of German Television as a Social, Cultural, and Discursive Phenomenon
Authors: Gorobiy Aleksey
Published: April 2024

Television is a global phenomenon with national peculiarities. This article introduces a chronological and comparative analysis of the development of television in West and East Germany. A systematic view of this phenomenon involves both technical and social aspects. From a technical innovation available to the privileged, it turned into a mass medium that performs an integrative function by shaping and broadcasting the current discourse. The research objective was to find out the specifics of television in Germany and correlate the global trends with the national context. The XX century erased the borders between such incompatible phenomena as dictatorship and democracy, and all these phenomena affected the content of TV shows, people’s attitude to television, its new genres, social functions, etc. The author revealed five stages in the development of German television. Stage I (late XIX century – 1945) was the age of technical discoveries, attempts at their practical implementation, and the early regular broadcasting during the period of National Socialism. Stage II (late 1940s – 1950s) marked the restoration of television broadcasting and the parallel development of television in the Federal Republic of Germany and the German Democratic Republic. Stage III (1960s –1970s) clarified the institutional framework and social functions of television. Stage IV (1980s – mid-1990s) saw the emergence of new broadcasting technologies and commercial TV channels, as well as the collapse of the Eastern bloc and the reunification of Germany. Stage V (since 1990s) is connected with digitalization.
Modus Reflection as Condition for Commenting in Virtual Conversations
Authors: Shpil'naya Nadezhda
Published: April 2024

Linguistics of response is a branch of dialog studies that focuses on response lines as part of a conversation, including conditions needed to implement the commenting intent in a virtual dialogue. According to the hypothesis, virtual commenting occurs when the initial line falls into the sphere of modus reflection of the native speaker. This condition realizes itself when the native speaker makes the decision to comment on an event. Modus reflection is a manifestation of the native speaker’s emotional and evaluative attitude to the original message. In this case, modus reflection appears as a metalinguistic activity. The descriptive analysis involved 614 response comments to an online news article entitled Subway Crossings: Street Gangs Where Flower Stalls Should Be. The research revealed three conditions when the commenting intent is realized in an online dialog: the initial line falls into the mode of agreement; the initial line falls into the mode of disagreement; the initial line falls into the neutral mode.

Published: April 2024

Measuring greenhouse gas emissions from wastewater treatment plants is of utmost importance in the context of climate change. However, due to their variability and complexity, it is a particularly challenging task in aerated reactors. The current methods involve capturing gas emissions from the water surface, measuring gas flow rates, and determining the concentration of the emitted gas at that location. Our study proposes a new, more efficient method that eliminates the need for gas flow rate measurements and additional equipment. The proposed technique uses a gas analyzer and a specially designed floating chamber to measure the transient trend of gas concentration within the chamber from the moment it is deployed to when it reaches a new steady state. Our research shows that this method accurately determines methane and carbon dioxide emissions from aerated reactors and potentially other gases emitted in wastewater treatment plants. It is cost effective, versatile, and simplifies the measurement process. This method facilitates the assessment of greenhouse gas emissions in wastewater treatment plants. Our findings are backed by comprehensive testing in the aeration tanks of a full-scale activated sludge plant, across diverse conditions, including fine- and coarse-bubble aeration.

Vastas áreas naturais sofreram grandes impactos ambientais com o avanço da urbanização e expansão agrícola, comprometendo o solo e inviabilizando sua regeneração natural. A restauração ecológica tem-se usado de novas tecnologias e estratégias para sua melhor eficácia. O lodo de esgoto compostado (LEC) para o plantio de mudas nativas cultivadas em viveiros tem sido cada vez mais utilizado, entretanto, ainda são raros os projetos que fazem uso deste biossólido na recuperação de ecossistemas. O experimento analisou a eficiência do LEC para o desenvolvimento de Anadenanthera peregrina. Foram selecionados 88 indivíduos distribuídos aleatoriamente em uma área de recuperação florestal e submetidos a quatro tratamentos: T1 – sem adubação (controle); T2 – 100% ureia nitrogenada; T3 – 50% LEC + 50% ureia; T4 – 100% LEC. Para a análise do desenvolvimento foram registrados os seguintes parâmetros biométricos: altura, espessura do caule à altura do solo e o diâmetro da copa. Houve um desenvolvimento superior para as mudas que receberam os tratamentos T4 e T3 em todos os parâmetros, comparadas aos grupos que receberam ureia nitrogenada ou controle. O LEC, aplicado em campo, acelerou o desenvolvimento de A. peregrina representando uma alternativa econômica e ecologicamente interessante para projetos de recuperação de áreas degradadas.

Los mercados actuales tienden a exigir cada vez más que las empresas se alineen a los Objetivos de Desarrollo Sostenible, por lo que, las organizaciones deben aprender a responder a las demandas de sus stakeholders para ser competitivas. Por otro lado, la literatura existente entiende la metanoia como un proceso de aprendizaje que realiza tránsitos entre perspectivas mentales en los individuos, la cual facilita cambios significativos del comportamiento. Como la teoría disponible aborda el tema principalmente desde la perspectiva individual y no de grupos de trabajo, la investigación explora la metanoia como dimensión del aprendizaje organizacional (AO) y posteriormente analiza su utilidad para adoptar los ODS y dar respuesta a las demandas de los stakeholders. Para esto, se utilizó la teoría fundamentada, aplicando observación no participante y entrevistas semiestructuradas a líderes del AO y gestión del conocimiento (GC), en siete organizaciones del sector privado con distintos niveles de formalidad en GC. El análisis de los datos se apoyó en los softwares Atlas.ti® y Cmaptools.

Un experimento fue llevado a cabo con el objetivo de evaluar el uso de la harina de vísceras de pollo (HVP) en reemplazo de la harina de pescado (HP) para el engorde de codornices machos,  desde los 21 a 49 días de edad. Se utilizaron 120 codornices machos de 21 días de edad para evaluar cuatro tratamientos: T1 (0% HVP + 10 % HP), T2 (3.5% HVP + 6.5 % HP), T3 (7% HVP + 3 % HP) y T4 (10% HVP + 0 % HP). Los resultados del experimento no mostraron diferencias significativas en peso corporal, ganancia de peso, consumo de alimento, conversión alimenticia, y rendimiento de carcasa. Al análisis de la retribución económica del alimento se determinó que el tratamiento con 7 % de harina de vísceras de pollo y 3% de harina de pescado (T-3) fue el más eficiente seguido por los tratamientos T4, T2 y T1.  Se concluye que la  harina de vísceras de pollo puede ser usada al 10 % en lugar  de  harina de pescado como fuente de proteína animal en dietas de engorde de la codorniz japonesa.

El presente trabajo de investigación se realizó en el Banco Nacional de Semen y la Unidad Experimental de Avicultura de la Universidad Nacional Agraria La Molina. Los objetivos de este estudio fueron evaluar comparativamente al ácido ascórbico y tocoferol sobre la fertilidad del semen refrigerado a 5°C de gallo. Se utilizaron 28 gallinas reproductoras de postura de 25 semanas de edad de las líneas Hy Line Brown y 6 gallos cruzados adultos de 30 meses de edad. Se establecieron 4 tratamientos designados como: T1 (ClNa al 1%, control), T2 (ácido ascórbico 200µg/ml), T3 (tocoferol 8µg/ml) y T4 (tocoferol 8µg/ml + ácido ascórbico 200µg/ml) diluidos en una proporción de 1:1 a una temperatura de 38°C y luego refrigerado a 5°C. La colección de semen fue de 3 veces por semana. La inseminación artificial fue vía vaginal con una jeringa de tuberculina modificada a una profundidad de 3 cm aproximadamente, con una dosis de 0.01 ml por gallina con 100 millones de espermatozoides y una frecuencia de inseminación de una vez por semana. Los huevos seleccionados por tratamiento fueron incubados para determinar la fertilidad (aquellos que presentaron el blastodisco germinal), incubabilidad y natalidad. Se utilizó un diseño completamente al azar y prueba de comparación de medias Duncan. Los mejores resultados para motilidad (69%), fertilidad (76.3%) se obtuvieron cuando en la dilución de semen se adicionó conjuntamente el tocoferol con el ácido ascórbico, siendo altamente significativo a los demás tratamientos utilizados. El mayor porcentaje de incubabilidad fue de 81.70% con el uso conjunto del ácido ascórbico y tocoferol en la dilución de semen.  En natalidad, el mayor porcentaje se logró con  la adición solamente de ácido ascórbico en la dilución de semen;  sin embargo,  estos resultados no son estadísticamente significativos entre tratamientos. Concluyéndose que el uso conjunto de tocoferol y ácido ascórbico en la dilución de semen, mantienen la motilidad espermática post refrigeración a 5°C dando mayores porcentajes de fertilidad, mas no en la incubabilidad debido a factores externos como la incubación propiamente dicha; sin embargo se pueden utilizar como componentes de un dilutor de semen de gallos para la inseminación artificial de gallinas ponedoras.
