A New Era of Armed Conflict: The Role of State and Non-State Actors in Cyber Warfare with Special Reference to Russia-Ukraine War
Authors: Khalil Ahmad , Bitar Mohammad , Anandha Krishna Raj S.
Published: November 2024

The use of cyber operations in armed conflicts has become a reality, with several states openly admitting to being involved in such activities. An increasing number of nations are developing military cyber capabilities, and the use of these operations is expected to rise. Advancements in offensive cyber capabilities have demonstrated that these operations can significantly impact civilian infrastructure and cause harm to humans. This study explores the complex application of international humanitarian law (IHL) to cyber warfare, focusing on the evolving roles of both state and non-state actors. It examines the difficulties in distinguishing between combatants and non-combatants in the light of the concept of direct participation in hostilities during cyberattacks. Furthermore, this paper examines the responsibilities and legal consequences for states that direct or control non-state actors and the need to adapt IHL to the specific nature of cyber conflicts. It underscores the crucial need for strong legal frameworks to protect civilians and uphold humanitarian principles in the digital era. This study employs cyberattacks which occurred during the Russian-Ukraine armed conflict as a case study.

Published: November 2024

The present study explores the process of agile transformation and the implementation of agile work practices in industrial companies, outlining an appropriate theoretical conceptual framework for the agile transformation of organizations. The purpose of this research is to discuss theoretical approaches explaining agile transformation and agile work practices in industrial companies, to present a conceptual framework, and to assess the effectiveness of the framework on the example of selected German industrial companies. For the research, a descriptive research design was chosen to substantiate the structural perspective of agile transformation and agile work practices in industrial companies and to reveal the interaction between these dimensions, while seeking to present the conceptual framework. A qualitative research strategy with semi-structured interviews was applied. This article proposes a concept of agile transformation of industrial companies, encompassing new insights. Agile transformation is referred to as the ability of companies to remain stable by employing agile work practices, preparing for and adapting to changes in the new environment while stressing the importance of the selected leadership style within the context of the organizational culture, and finally, using the experience gained to strengthen the agile transformation competencies and emphasizing the leadership of the managers as they perform a decisive role in implementing agile transformation in the company, managing the agile work practices and uncertainty. At the end of the article, a conceptual framework is presented that reflects the key structural parts. The conceptual framework was validated on the example of selected five strongest German industrial companies. Expert assessments revealed the choice of the leader as trainer (as the most suitable leadership type) and its effect on the implementation of agile transformation in the company, seeking to navigate to an agile way of working (when the manager helps identify the areas of improvement in agile work methods and processes). The experts also highlighted the effectiveness of agile work practice implementation (allowing to suggest expansion opportunities for industrial companies, enabling the effectiveness and sustainable competitiveness in the sector) and noted the interaction between the two dimensions.

Authors: Liutkevičius Markko , Samaranayaka Piyumi , Nõmmik Sander , Yahia Sadok Ben , Weck Marina
Published: November 2024

The modern labor market faces complex challenges stemming from various factors, such as demographic shifts, the far-reaching impacts of digital and technological evolution, changing job profiles, and job losses due to automation and the green-economy transition. As labor market challenges escalate, it becomes increasingly vital for public employment services (PES) to gain a deeper understanding of their clients and the specific labor markets in which they operate. Although, in their current form, these services often help only unemployed people, implementing AI technologies has the potential to significantly broaden PES support for the wider public. Unfortunately, the EU’s PES sector has been slow to implement AI technologies to support clients with services such as skills extraction from CVs and job offers, jobseeker matching, and recommending relevant jobs or training. This study examines the perspectives of a PES’ external user groups and internal stakeholders to establish a baseline for implementing such technologies into existing self-services. The findings emphasize that while AI has transformative potential, deploying it effectively necessitates a holistic understanding of the existing PES ecosystem and a strategic approach to requirement gathering.
Nutritional status of female rats after acute intoxication with ethyl alcohol and treatment with ketoprofen lysine salt or ketoprofen
Authors: Nieradko-Iwanicka Barbara , Ruszel Kinga
Published: November 2024

Ketoprofen lysine salt (KL) is a new non- steroidal anti-inflammatory drug (NSAID) competing with ketoprofen (K) on the market. The former is believed to have gastroprotective properties and both to kill acute pain. In East Europe binge drinking and taking NSAIDs after is common. Some people use NSAIDs to treat the discomfort when they sober up. Vomiting after alcohol intoxication and gastritis after use of NSAIDs may produce malnutrition. The aim of the study was to compare nutritional status in female rats treated with KL or K after acute intoxication with ethyl alcohol. In this animal model we wanted to mimic human cases of NSAIDs use on the day(s) after binge drinking. The experiment was carried out on 36 female Wistar rats divided into 6 groups of 6: 1. treated with 50% etanol; 2. 0.9% NaCl; 3. 0.9% NaCl and K; 4. 50% etanol and K; 5. 0.9% NaCl and KL; 6. 50% etanol and KL.

On day 7 animals were sacrificed. Their body, liver and kidney mass was recorded. The blood was obtained to measure blood morphology and biochemical parameters. K and alcohol in group 4 limited body mass gain (p<0.05 vs ethanol-group 1) and lowered albumin concentration (p<0.05 vs control-group 1). There was also a statistically significant decrease in the level of serum albumin of rats receiving KL (group 5) compared to the saline (group 2).

K affects the nutritional status more than KLS after alcohol intoxication.
[18F]fluorocholine PET vs. [99mTc]sestamibi scintigraphy for detection and localization of hyperfunctioning parathyroid glands in patients with primary hyperparathyroidism: outcomes and resource efficiency
Authors: Rep Sebastijan , Sirca Klara , Lezaic Ema Macek , Zaletel Katja , Hocevar Marko , Lezaic Luka
Published: November 2024

Background

Minimally invasive parathyroidectomy is the treatment of choice in patients with primary hyperparathyroidism (PHP), but it needs a reliable preoperative localization method to detect hyperfunctioning parathyroid tissue. Higher sensitivity and lower radiation exposure was demonstrated for [18F]fluorocholine PET/CT (FCh-PET/CT) in comparison to [99mTc]sestamibi (MIBI) scintigraphy. However, data of its efficiency in resource use and patient outcomes is lacking. The aim of our study was to determine the resource efficiency and patient outcomes of FCh-PET/CT in comparison to conventional MIBI scintigraphy.

Patients and methods

A group of 234 patients who underwent surgery after MIBI scintigraphy was compared to a group of 163 patients who underwent surgery after FCh-PET/CT. The whole working process from the implementation of imaging to the completion of surgical treatment was analyzed. The economic burden was expressed in the time needed for the required procedures.

Results

The time needed to perform imaging was reduced by 83% after FCh-PET/CT in comparison to MIBI scintigraphy. The time needed to perform surgery was reduced by 41% when intraoperative parathyroid hormone monitoring was not used. There was no significant difference in the time of surgery between FCh-PET/CT and MIBI scintigraphy.

Conclusions

FCh-PET/CT reduces the time of imaging, the time of surgery and potentially reduces the number of reoperations for persistent disease.

Published: November 2024

Thei purpose of thisi study is to evaluate the physical quality of Bali beef marinated with Klanceng Honey (Trigo- na Sp.) and establish its optimal influence. The marinating of the beef took place at room temperature for 30 minu- tes. Four treatments and seven replications were used in the fully randomized research design. The four treatments included non-marinated meat (P0); meat marinated with 5 ml of Trigona honey (P1); meat marinated with 10 ml of Trigona honey (P2); and meat marinated with 15 ml of Trigona honey (P3). In this investigation, the following variables were noted: pH level, meat color, cooking loss, raw loss, and water holding capacity. The findings revea- led that marinating Bali beef with Trigona honey significantly affected pH, cooking loss, raw loss, and meat color (P0.05), but had no significantly different impact on water holding capacity (P>0.05). Because the values for pH, DIA, brightness (L*), and redness (a*) have decreased, while the values for cooking loss, raw loss, and yellowness (b*) on meat color have increased, this study concludes that Klanceng Honey (Trigona Sp.) as a marinade for Bali beef has not been able to improve the physical quality of Balii beef.

Published: November 2024

Gastrointestinal nematodes are one of the causes of reduced production efficiency in sheep and goats in Indone- sia, especially the Haemonchus contortus abomasum parasite. This parasite causes Haemonchosis disease which causes anemia and is fatal for productive sheep and goats. This study evaluated the inhibition of egg hatchability and mortality of adult H. contortus worms from in vitro infusaion of Indigofera tintoria L leaves. Indigofera leaf infusaion testing at five concentrations of 20%, 40%, 60% and 80%(w/v) was used both treatments. Albendazole at a dose 0f 2 mg/ml was used as apositive control, while negative control used 0.9% NaCl solution. At the highest concentration of 80% Indigofera leaf infusaion was able to inhibit egg hatching by 95.60% and had a mortality rate against adult H. contortus worms by 89.67%. The 80% concentration has the same effect when compared to the positive control using Albendazole. Phytochemical analysis of Indigofera tintoria L leaves contains condensed tannins and is useful as a bioanthelmintic.

Published: November 2024

This study aims to find out how producing broiler chickens performs when corn is replaced with brem dregs. The 200 Lohman MB 202 Platinum chicken strain, comprised of one-day-old unsexed chicks, was employed in the investigation. There were five treatments in Complete Random Design (CRD). P0, the control group, was fed untreated feed, whereas P1, P2, P3, and P4 were fed brem dregs in various amounts as a substitute for corn. Every treatment was carried out four times. The data were then statistically analyzed using analysis of variance (ANOVA) by a completely randomized design. Duncan’s multiple range test should be performed if the results show a signifi- cant difference (P<0.05) or a highly significant difference (P<0.01). The results showed that feed conversion, IOFC, body weight gain, and consumption were all significantly (P<0.01) impacted by the use of brem dregs. The results of this study demonstrate that brem dregs can be fed to broiler chickens in place of corn at feeding levels of up to 40%.

Published: November 2024

Anion exchange resins (AERs) have been widely used for the removal of per- and polyfluoroalkyl substances (PFAS) from water. However, regardless of whether AERs are regenerable or single-use, the disposal of end-of-life AERs presents significant challenges. Conventional waste management strategies, such as landfill disposal and incineration, are increasingly under scrutiny and may face impending bans due to environmental concerns. This study introduces a non-thermal, solvent-free process for the effective destruction of PFAS on AERs by co-milling piezoelectric boron nitride (BN) powders with contaminated AERs and stainless steel (SS) balls. The approach demonstrated the destruction of PFOS and achieved 80% defluorination when applied to two types of AERs (PFA694E and AmberLite IRA 67) pre-loaded with PFOS. Comprehensive targeted PFAS analysis and suspect screening analysis of transformation products elucidated the reaction mechanisms and confirmed that the functional groups of AERs did not participate in the reaction. The process’s effectiveness was further validated in treating field-collected single-use AERs (PFA694 and AmberLite PSR2 Plus) contaminated with PFAS mixtures of varying chain lengths and head groups. After treatment, PFAS levels on the AERs were reduced to below ng/g detection limits, and no PFAS release was observed in standard leaching tests.

The structure’s overall response was studied, meanwhile, the seismic resilience of the building was evaluated from three aspects: repair cost, repair time, and casualties. The results show that viscous dampers can effectively reduce the repair cost, repair time, and casualties under earthquakes. Compared with the structure without dampers, the repair cost and repair time of the structure with dampers have been reduced by 67% and 69% respectively under moderate earthquakes, 42% and 39% respectively under rare earthquakes, and the seismic resilience grade has been increased from zero to one star.

Objective: To assess surgical outcomes of women submitted to the adapted sacrospinous fixation (SSF) at a school hospital in northeastern Brazil for apical prolapse repair. Methods: Retrospective study with medical records of women submitted to the adapted SSF at a reference center in Brazil (2015 to 2019). All women submitted to this SSF were included, and those with pelvic organ prolapse (POP) recurrence, repair using other techniques, or unavailable medical records were excluded. The anatomical result, surgical characteristics, and associated complications and recurrence were evaluated. The chi-square and Fisher's exact test were used for statistical analysis, using a significance level of 5%. Results: A total of 198 medical records were included. The mean age was 65.1 ± 8.2 years; most had less than eight years of education, were menopausal, multiparous, and with urinary incontinence. The postoperative POP stage significantly improved at all compartments. The complication rate was 15.7%, especially due to de novo urinary incontinence (n = 12; 6%). Five cases of mesh-related complications (5%) were observed. The median follow-up was nine months, with 8.4% of POP recurrence and reoperation. POP recurrence or mesh-related complications were not associated with sociodemographic, clinical, or surgical characteristics.[...]

Offshore wind development in the Philippines remains at a standstill owing to the relatively high cost of the technology despite the government’s ambitious goal to produce 19–50 GW by 2050. Previous studies have shown that bottom-fixed turbines can be utilized to reach the lower end of the production target. Still, most potential can be achieved in greater depths where floating turbines are more appropriate. Therefore, this study performs a techno-economic assessment for floating offshore wind energy using global information system (GIS) software to analyze the technical and economic potential of floating offshore wind energy in the Philippines. Data from the Global Wind Atlas was used to obtain the technical potential of sites that may be used for floating offshore wind turbines. Exclusion zones are set up according to distance from shore, marine protected areas, oil and petroleum sites, shipping lanes, and submarine cables. Factors on distance to shore, port, and substation, as well as natural hazards and bathymetry, are considered according to a weighted analytic hierarchical process. The net present value (NPV) of each potential site is then calculated by considering the capital, operational, and decommissioning cost of a site at a 6% interest rate and 25 years of operational life. Results show that there is a total potential of 813 GW that can be produced from a total of 20 non-contiguous sites. However, the current feed-in tariff (FIT) rate of 8.53 Php/kW is insufficient to make any sites profitable as all NPVs are negative. The breakeven prices can guide the Philippines government to set an appropriate rate at a minimum of 10.14 Php/kW.

Проблема нарушения земель под влиянием нефтяного загрязнения является чрезвычайно важной. Однако многие вопросы, в том числе связанные с оценкой воздействия нефтяного загрязнения на почву, до сих пор остаются нерешенными. Одним из основных источников данных для экологического мониторинга в настоящее время являются материалы дистанционного зондирования. Ставится задача обнаружения, идентификации, оценки типа и степени загрязнения внешней среды спектральными методами, в основном отражательной спектрометрии. Известно, что для количественной оценки степени содержания нефтяных углеводородов во внешней среде используются спектральные индексы. При этом прямое применение этих индексов без учета ряда влияющих факторов может привести к неоднозначным результатам. Целью настоящей статьи является повышение достоверности результатов количественной оценки содержания нефтяных углеводородов в почвенных грунтах с применением нефтяного индекса Oix, характеризующего степень загрязнения почвы сырой нефтью. Для повышения достоверности определения нефтяного индекса Oix предлагается метод, предусматривающий учет влияния влажности загрязненной нефтью почвы и реализуемый в двух вариантах – искусственное увлажнение и сушка почвы. В случае малого объемного содержания нефти в почве для решения данной задачи рекомендуется увлажнение почвы, при большей степени загрязненности – сушка.

The problem of land disturbance caused by oil contamination is extremely important. However, many issues, including those related to the assessment of the impact of oil contamination on the soil, still remain unresolved. Currently, one of the main sources of data for environmental monitoring are remote sensing data. The task of detection, identification, assessment of type and degree of contamination of environment using spectral methods, mainly reflectance spectrometry, is set. It is known that spectral indices are used to quantify the oil hydrocarbon content in the environment. However, direct application of these indices without taking into account a number of influencing factors can lead to ambiguous results. The purpose of this paper is to improve the reliability of the results of quantitative assessment of the petroleum hydrocarbons content in soils using the oil index Oix, which reflects the degree of soil contamination by crude oil. To improve the reliability of the Oix oil index estimation, we propose a method of moistening/drying oil-contaminated soil. In case of low volumetric oil content in the soil, for solving this problem it is recommended to moisten the soil; in case of higher degree of contamination, it is recommended to dry the soil.
