BACKGROUND

Type 2 diabetes mellitus (T2DM) is often accompanied by impaired glucose utilization in the brain, leading to oxidative stress, neuronal cell injury and infla-mmation. Previous studies have shown that duodenal jejunal bypass (DJB) surgery significantly improves brain glucose metabolism in T2DM rats, the role and the metabolism of DJB in improving brain oxidative stress and inflammation condition in T2DM rats remain unclear.

AIM

To investigate the role and metabolism of DJB in improving hypothalamic oxidative stress and inflammation condition in T2DM rats.

METHODS

A T2DM rat model was induced via a high-glucose and high-fat diet, combined with a low-dose streptozotocin injection. T2DM rats were divided into DJB operation and Sham operation groups. DJB surgical intervention was carried out on T2DM rats. The differential expression of hypothalamic proteins was analyzed using quantitative proteomics analysis. Proteins related to oxidative stress, inflammation, and neuronal injury in the hypothalamus of T2DM rats were analyzed by flow cytometry, quantitative real-time PCR, Western blotting, and immunofluorescence.

RESULTS

Quantitative proteomics analysis showed significant differences in proteins related to oxidative stress, inflammation, and neuronal injury in the hypothalamus of rats with T2DM-DJB after DJB surgery, compared to the T2DM-Sham groups of rats. Oxidative stress-related proteins (glucagon-like peptide 1 receptor, Nrf2, and HO-1) were significantly increased (P < 0.05) in the hypothalamus of rats with T2DM after DJB surgery. DJB surgery significantly reduced (P < 0.05) hypothalamic inflammation in T2DM rats by inhibiting the activation of NF-κB and decreasing the expression of interleukin (IL)-1β and IL-6. DJB surgery significantly reduced (P < 0.05) the expression of factors related to neuronal injury (glial fibrillary acidic protein and Caspase-3) in the hypothalamus of T2DM rats and upregulated (P < 0.05) the expression of neuroprotective factors (C-fos, Ki67, Bcl-2, and BDNF), thereby reducing hypothalamic injury in T2DM rats.

CONCLUSION

DJB surgery improve oxidative stress and inflammation in the hypothalamus of T2DM rats and reduce neuronal cell injury by activating the glucagon-like peptide 1 receptor-mediated Nrf2/HO-1 signaling pathway.

The use of #digitalpowerups is a technique that involves associating keywords with prompts in online discussion forums, which enables students to have more choice and voice. These powerups not only help structure responses but also enrich discussions and develop academic skills necessary for online assignments. The approach leverages the social media interaction space of discussion forums by introducing hashtags that remind students of the prompt being addressed and indicate the level of Bloom's being engaged. By using the powerups, students can engage in mid-levels and higher-order levels of Bloom's, along with the lower levels that they typically engage in based on the design and facilitation of the discussion. Students typically participate in the lower levels of Bloom's taxonomy (#remember, #understand) due to the way the discussion is structured and facilitated. However, the use of #digitalpowerups encourages students to move beyond these levels and engage in mid-levels (#apply, #analyze, #evaluate) and higher-order levels (#create, #connect) during discussions.The powerups also scaffold or frame student responses with habits of mind skills. This article examines how the #digitalpowerups strategy supports learning in a virtual community for Environmental Concerns in the Environmental Sociology Course through content analysis of student discussion postings. The primary data (total of 375 postings) were collected from the Environmental Sociology Class throughout the following academic years: Fall 2020 (96 postings), Fall 2021 (67 postings), Spring 2022 (92 postings) and Spring 2023 (120 postings).

The paper presents a concept for the realization of a fully digital substation using the IEC 61850 standard. The basis of the system is the way of realization of the architecture of the precess bus and station bus Ethernet network. The use of non conventional measuring transformers (low power) with associated coupling devices makes it possible to transmit measuring signals from one place via the network in digital format to other devices (Intelligent electronic device). The use of new types of sensors that have the ability to convert output signals into digital format allows immediate monitoring of system elements such as switches, disconnectors, own consumption, power transformers. On the other hand, since the number of information that is generated online in the system drastically increases, it is necessary to implement special HMI applications that process this information.

The conversion of solar radiation energy by using photovoltaic (PV) panels is one of the most common forms of environmentally friendly electricity generation. It is known that a modular approach in the design of PV systems achieves benefits such as greater reliability and flexibility while increasing the total installed power. It has been observed that depending on the system’s nominal power, different modular approaches and topologies of the converter are recommended. This paper presents an analysis of the dependence of the total price and efficiency of the power stage with the increase of the installed power of the power plant. The analysis was performed on different modular approaches and topologies of the converter, which contains high-frequency reactive elements. These topologies are characterized by high power density, high efficiency and, often, galvanic isolation. Additionally, this analysis takes into account the possibility of oversizing transformers, which is a key factor in terms of flexibility of individual modular systems. Based on the conducted study, guidelines for the selection of the optimal modular approach and adequate topology for the desired installed power of the solar power plant are given.

The increasing trend of distributed solar power sources dictates the development of compact, efficient and cheap power converters. Traditional approach for achieving galvanic isolation in solar power system requires the usage of low- frequency transformer along with a solar inverter. By using topologies that integrate high-frequency (HF) transformer within themselves, system’s cost and size are being reduced. However, in order to achieve reasonable efficiency, the windings in HF transformer should consist of specific expensive litz wires. In this paper, the comparison of two approaches to galvanic isolation in solar inverters has been presented – the one with 50 Hz transformer versus the other 200 kHz transformer solution. Analyzed parameters were efficiency, volume, and cost. Grid-side converter in both cases is considered to be 1 kW single-phase inverter with LCL output filter. Finally, quick guide for HF transformer design is formulated in order achieve efficient, low-cost and compact galvanic isolation.

The study examines the impact of foreign aid on agricultural research in Ethiopia over the period 2011-2020. According to the study, donor allocations averaged 23% of the total amount of funds received by the institution in the form of loans and grants in 2020. Donors' investment in Ethiopian agricultural research is decreasing and negative growth has been recorded, from 33% in 2016 to 23% in 2020. Donor aid funding decreased by 51.3% in 2019 and 84.6% in 2020 compared to 2018. In addition to joint research and financial investment, 65% of improved germplasm comes from donors directly through adaptation research or parent material. Furthermore, for which information is collected and available, 7.3% of trained scientists and 57% of fixed assets were financed by donors. The majority of the donor-funded projects focused on short-term goals that did not align with national priorities or focused on commodities of relatively low economic value to the country. Therefore, a new financial framework is needed for the government to set strategic priorities for donors to contribute to the country.

Published: February 2024

The purpose of this research was to investigate the effect of the zone, season and collecting point on the quality of milk produced in a semi-arid steppe zone of Algeria. Throughout the four seasons of the year and separated into five zones, this study was done on 334 farms and 25 collectors. It involved 1336 milk samples. The obtained results showed that the physico-chemical and microbiological quality of milk produced in semi-arid zones is influenced by the zone, season, and collecting point. The collecting point behaves similarly to the season, except for pH. They showed a highly significant effect (p ≤ 0.01) for Staphylococcus aureus to a very highly significant one (p ≤ 0.001) for all other physico-chemical characteristics (acidity, density, freezing point, wetting, fat, protein and total solids) and microbiological parameters (thermo-tolerant coliforms, aerobic germs at 30°C, Listeria monocytogenes and Salmonella). On the other hand, the effect of the zone was variable. It is significant (p ≤ 0.05) for Listeria monocytogenes, highly significant for freezing point and wetting, and very highly significant for the other parameters, except for fat content and Salmonella which were not influenced by the zone. Among other things, pH was not affected by the collection point. This variability in milk’s quality is the result of above mentioned factors, either considered independently or in combination. The collection point highlights the mixing effect. The season acts directly through its temperature (condition of transport and storage of milk) or indirectly on the feeding of the animals and the area directly by its climate or indirectly through its plant cover.

Para tanto, utilizou-se da pesquisa bibliográfica com abordagem dedutiva, argumentativa e estruturalista, considerando as contribuições de autores como Bitencourt (2011), Born (2011), Capez (2011), Cunha (2008), Grecco (2011), Luisi (1991), Martins (1997), Meirelles (2001), Mello (2007), Mello (2012), Souza (2014), Valla (2012) e Vitta (2003). Nesse sentido foi possível tornar manifesta a subjetividade dos critérios dosimétricos utilizados atualmente na mensuração da sanção disciplinar aplicadas aos militares estaduais do Paraná e fundamentar a possibilidade de estabelecer parâmetros objetivos de dosimetria, alicerçadas nos princípios da razoabilidade e proporcionalidade e valores éticos institucionais, sem, contudo, retirar o poder discricionário da autoridade administrativa julgadora. Concluiu-se que é possível aperfeiçoar a dosimetria da sanção disciplinar, tornando-a mais objetiva do que subjetiva, ao se estabelecer o grau lesivo das transgressões disciplinares através da vinculação de cada conduta aos valores éticos violados.
Generating LTL Formulas for Process Mining by Example of Trace
Authors: Komatsu Kota , Horita Hiroki
Published: February 2024

Process mining enables efficient and exhaustive analysis of business processes based on event data. Process mining tools such as linear temporal logic (LTL) Checker allow users to verify temporal properties of business processes for traces by providing a description based on LTL. However, it is difficult for many users to understand and use LTL-based mathematical notation. Therefore, there is a need for a method to describe temporal properties even for those who are not familiar with mathematical notation. Several methods have been proposed to automatically generate logical expressions to address these issues, but there are still problems related to the data format and the limited scope of the expressions that can be described. In this study, we proposed a method based on the satisfiability problem (SAT) for event logs in eXtensible Event Stream format used in process mining, and it is verified how well it can automatically generate temporal properties in business processes. We conducted experiments using two types of event logs to demonstrate the effectiveness of the proposed method.

Scoring Sustainability Reports for Assessing Environmental and Social Dimension of Leading Energy Sector Companies
Authors: Mehra Pragati
Published: February 2024

The looming threat of climate change is increasingly placing the sustainability of businesses under scrutiny. The power sector in India offers a compelling context to explore the scope of ESG disclosures. The country heavily relies on coal, oil, and gas for extensive electrification, making it the world's fourth-largest emitter of pollution, releasing 2.65 billion metric tonnes of carbon into the atmosphere annually. In this paper an attempt has been made to review and analyse the Business Responsibility and Sustainability Reports of Energy sector companies in India. A distinction has also been made in public and private sector companies. Sustainability Reporting Maturity Model released by ICAI has been used to score the companies for the social and environmental indicators reported by them in the BRSR. It was found that although private sector companies are reporting the environmental indicators better, the public sector is leading in reporting social indicators. However, when it comes to overall performance, public sector companies outperform private sector companies.

Block chains are now firmly established as a digital technology that combines cryptographic, data management, networking, and incentive mechanisms to support the verification, execution, and recording of transactions between parties. While block chain technologies were originally intended to support new forms of digital currency for easier and secure payments, they now hold promise as a new foundation for all forms of transactions. Agribusiness stands to become a key beneficiary of this technology as a platform to execute ‘smart contracts’ for transactions, particularly for high-value produce. First it is important to distinguish between private digital currencies and the distributed ledger and block chain technologies that underlie them. The distributed and cross- border nature of digital currencies like Bit coin means that regulation of the core protocols of these systems by central banks is unlikely to be effective. Monetary authorities are focused more on understanding ‘on-ramps’ and ‘off-ramps’ that constitute the links to the traditional payments system rather than being able to monitor and regulate the currency itself. In contrast to the digital currency feature of block chain, the distributed ledger feature has the potential for widespread use in agribusiness and trade financing, especially where workflows involve many different parties with no trusted central entity

As the increasing number of deepfake content poses a growing threat to multimedia integrity, this paper proposes a robust deepfake detection approach based on a hybrid architecture. The proposed framework combines the power of Residual Networks (ResNet) for spatial feature extraction and Long Short-Term Memory (LSTM) with Convolutional Neural Networks (CNN) for temporal dependency modeling. The ResNet component captures complicated patterns in facial and contextual information, whereas the LSTM-CNN module identifies dynamic facial expressions and movements across multiple frames. Transfer learning strategies are used to improve model generalization by combining pre-training on a large dataset with fine-tuning on deepfake data. Experimental evaluations on a variety of deepfake datasets show superior accuracy, precision, and recall, demonstrating the hybrid architecture's efficiency in dealing with the evolving challenges posed by more advanced deepfake generation techniques. In conclusion, our novel deepfake detection framework employs an effective combination of ResNet and LSTM-CNN, demonstrating a promising solution that not only advances the state-of-the-art in multimedia forensics but is also resistant to adversarial attacks. This hybrid model, which effectively combines spatial and temporal information, has the potential to significantly improve the accuracy and reliability of deepfake detection systems in the face of emerging digital threats.
