Torrential Hazards’ Mitigation Measures in a Typical Alpine Catchment in Slovenia

Different sediment-related disasters due to torrential hazards, such as flash floods, debris flows, and landslides, can occur in an Alpine torrential catchment. When protecting infrastructure and human lives, different structural and non-structural protection measures can be used to mitigate permanent and future risks. An overview of the mitigation measures constructed near the Krvavec ski resort in northwest Slovenia (Central Europe) is presented. In May 2018, an extreme debris flood occurred in this area, causing significant economic damage. After the May 2018 event, different field investigations (i.e., geological and topographic surveys) and modeling applications (e.g., hydrological modeling, debris flow) have been conducted with the purpose of preparing the required input data for the design of protection measures against such disasters in future—due to climate change, more disasters are expected to happen in this torrential watershed. The mitigation includes the restoration of local streams, the construction of a large slit check dam for sediment retention, the construction of several smaller check dams and the construction of 16 flexible net barriers with an estimated ~8000 m3 retention volume for controlling in-channel erosion in steep torrential streams. Additionally, in order to observe and monitor potential future extreme events, an extensive monitoring system has been established in the investigated area. This monitoring system will cover measurements of flexible net corrosion, the estimation of concrete abrasion at check dams, periodical geodetic surveys using small drones (UAV), hydro-meteorological measurements using rainfall gauges and water level sensors. The recent extreme floods of August 2023 also hit this part of Slovenia, and this combination of technical countermeasures withstood the event and prevented large amounts of coarse debris from being transported to the downstream section and devastating infrastructure, as was the case in May 2018 during a less extreme event. Therefore, such mitigation measures can also be used in other torrential catchments in the Alpine environment.

Application of the Ground Penetrating Radar (GPR) and Electromagnetic (EM34-3) Geophysical Tools and Sedimentology for the Evaluation of the Subsurface of Sites Earmarked for Aquaculture Ponds in the Amazon Region of Northern Brazil

The present study evaluated the application of Ground Penetrating Radar and Electromagnetic Induction geophysical tools combined with sedimentology for the description of the subsurface of sites destined for the installation of ponds for an extensive freshwater fish farming system. Two areas with similar topographic characteristics (flat land near bodies of water) were investigated in the Amazon region of northern Brazil: Area 1—the future site of an aquaculture research center, and Area 2—an established fish farming operation. These tools performed well in the evaluation of the suitability of the terrain for the installation of aquaculture ponds. The application of these tools can, thus, be recommended for aquaculture projects, given that it provides advanced knowledge on the characteristics of the local soils, which is extremely important to guarantee the sustainability of any aquaculture operation. These data can help minimize the environmental impacts of the process, while maximizing the economic returns to the installation of an aquaculture operation.

Eliminating the thermal degradation of polylactic acid by the modification of a macromolecular epoxy‐type chain extender

AbstractA novel macromolecular epoxy chain extender was synthesized and used to modify the PLA resin for developing conventional melt extrusion technology. Fourier‐transform infrared spectroscopy (FTIR), gel permeation chromatography (GPC), and 1H nuclear magnetic resonance (1H NMR) characterized the successful synthesis. For the first time, the molecular weight plays a key role in preventing thermal degradation and chain extension were discussed experimentally. Macromolecular chain extender showed superior advantages in that the chain extender with higher molecular weight was easier to get the long chain branched (LCB) structure in the modification of PLA. The characterization by rotational rheometer, GPC, melt index, chemical titration, and differential scanning calorimeter (DSC), results demonstrate that the macromolecular epoxy chain extender could decrease the concentration of terminal carboxyl groups and increase with only 0.5% dosage. At a concentration ≥2%, there were a large number of long chain branched structures in the chain extension system for modified PLA. It showed better melt strength and would influence the crystallinity of PLA which would significantly improve the processability of PLA, especially in high‐temperature extrusion, blow molding, spinning, and other processing technologies and applications.

Carbon accounting per unit of food and unit of land in food production systems of Argentina

Based on the notion of Life Cycle Assessment (LCA), the carbon footprint (CF) is an extensively used concept that quantifies and informs carbon load per unit weight (e.g., kg C/ton food) in the food system. In line with LCA, the CF computes emissions at pre-farm, farm and post-farm stages throughout a given food chain. However, the CF contribution to C accounting may sound incomplete because gains of C by photosynthesis at the farm stage are set aside. The notion of carbon balance (CB), which computes both C emission and capture (e.g., in ton C/ha), may be relevant in food production systems based on the extensive use of land. Because of the high weight that farm processes have on entire food chains, in this investigation we focused the analysis on the farm stage. In order to assess the suitability of CF and CB in extensive food production systems, we analyzed results from CF and CB in 70 surveyed commercial farms distributed across three large climatic regions (subtropical and temperate) of Argentina. The CF and CB of four relevant farming activities (beef, maize, soybean and wheat production) were compared during the year 2019. The comparison yielded contrasting results and opened space for different interpretations: The notion of CF seems to be useful in intensive food-production systems that rely on inputs and activities that depend on a high consumption of fossil fuels. Conversely, CB appears to be useful in food-production systems associated with an extensive use of land and the gain of C through a large plant-photosynthesis platform.

Immediate neural impact and incomplete compensation after semantic hub disconnection

The human brain extracts meaning using an extensive neural system for semantic knowledge. Whether broadly distributed systems depend on or can compensate after losing a highly interconnected hub is controversial. We report intracranial recordings from two patients during a speech prediction task, obtained minutes before and after neurosurgical treatment requiring disconnection of the left anterior temporal lobe (ATL), a candidate semantic knowledge hub. Informed by modern diaschisis and predictive coding frameworks, we tested hypotheses ranging from solely neural network disruption to complete compensation by the indirectly affected language-related and speech-processing sites. Immediately after ATL disconnection, we observed neurophysiological alterations in the recorded frontal and auditory sites, providing direct evidence for the importance of the ATL as a semantic hub. We also obtained evidence for rapid, albeit incomplete, attempts at neural network compensation, with neural impact largely in the forms stipulated by the predictive coding framework, in specificity, and the modern diaschisis framework, more generally. The overall results validate these frameworks and reveal an immediate impact and capability of the human brain to adjust after losing a brain hub.

Assessing the reentry needs of incarcerated individuals with co-occurring opioid use and mental health concerns

Individuals with co-occurring mental health concerns and opioid use disorder (COD) are at high risk of mortality and poor social and health outcomes upon release, and there is a need to better understand the unique reentry needs of this population. The high level of need experienced by individuals with COD will demonstrate a necessity for comprehensive reentry support which includes mental health treatment, Medications for Opioid Use Disorder (MOUD), social services such as education, employment, Medicaid, and housing. This sample included 490 adults from a targeted jail/prison reentry program for individuals experiencing COD in a Midwestern state. Program participants had histories of trauma (90%), homelessness (62%), and inpatient psychiatric care (38%). Further, most participants reported needing medical attention for a physical problem (70%) at baseline. Finally, participants had extensive criminal-legal system exposures, with an average of 10 lifetime arrests outside of their current incarceration (M = 9.91, SD = 8.74). The findings have important implications for expanding reentry services to support individuals with COD. This includes the need to begin services prior to release and ensuring the coordination and continuity of care with community-based treatment providers.

Optimization of Enterprise Resource Planning (ERP) Applications on The Crew Contract Extension System At PT. Sinarmas LDA Maritime

Technological developments are needed in today's digital era because they can help all human activities. PT. Sinarmas LDA Maritime created an Enterprise Resource Planning (ERP) application. The ERP application is used to simplify employees' work in inputting data and monitoring the working period of the crew and the validity period of documents. However, in using the ERP application, there are obstacles to the crew contract extension system, which still uses paper forms, so inputting data into the application takes a long time. Besides that, the ERP application is very dependent on the internet network. This study aims to determine the constraints in optimizing Enterprise Resource Planning (ERP) applications on the crew contract extension system with the addition of problem solvers. This research method uses a qualitative description approach by conducting observations, interviews, literature studies, and documentation directed at competent and directly involved informants and using SWOT analysis techniques to determine strategic factors for optimizing Enterprise Resource Planning (ERP) applications by linking research data results. Based on the research that has been done, it was found that optimizing the Enterprise Resource Planning (ERP) application in the crew contract extension system is filling in crew data that still uses paper forms and is dependent on the internet network. Using a paper form is changed to using a G-form so that the input of crew data for extended counters is more effective and efficient. As well as the need for outreach to the ship's crew in order to know the stages of filling in the data. The results of the SWOT analysis show that the Enterprise Resource Planning (ERP) application is in a progressive strategy position, meaning that obstacles in optimizing ERP applications can be overcome because the company is able to take advantage of its strengths and opportunities.

Effect of olive cake supplementation on faecal microbiota profile of Holstein and Modicana dairy cattle

The present study aimed to investigate the effect of olive cake supplementation on faecal microbiota of Holstein (n = 16) and Modicana (n = 16) dairy cows. Although no difference in richness was detected, within breeds and between the two dietary treatment, the PERMANOVA analysis applied to the beta diversity allowed to discriminate samples according to breeds (p < 0.001) and treatment (p < 0.001). In Holstein cows, the olive cake supplementation led to the increase of Pseudobutyrivibrio and Christensenellaceae_R7-group genera (p < 0.05) recognized as health-promoting or associated with feed efficiency. Differently, no difference was detected between control and treated groups for Modicana suggesting a high adaptive capacity to diet changes. In addition, the higher prevalence of Firmicutes phyla in the Modicana microbiota reflected its better capacity to digest the fibrous sources. Our study supports the suitability of olive cake as a feed supplement for cows and could help validating a sustainable livestock system in the Mediterranean area, characterized by a relevant oil production and by a native breeds reared with extensive systems.

Prevalence of subclinical mastitis, associated risk factors and antimicrobial susceptibility pattern of bacteria isolated from milk of dairy cattle in Kajiado Central sub-county, Kenya.

Literature is scarce on the occurrence of bovine mastitis and antimicrobial resistance among dairy animals kept by pastoralists in the Kenya. A cross-sectional study was carried out to investigate the prevalence and risk factors of subclinical mastitis (SCM) and evaluate the antibiotic sensitivity of bacteria isolated from dairy cattle kept by farmers in Kajiado Central sub-county, Kenya. A total of 202 lactating cows from 40 farms were sampled. Milk from the cows was screened for SCM using the California mastitis test, and the bacteria present in the milk samples were determined using standard bacteriological methods. The sensitivity of the isolated coagulase-negative staphylococci (CNS) and Staphylococcus aureus against antibiotics was tested using the Kirby-Bauer disk diffusion method. The prevalence of SCM at quarter- and cow-level was 31.7% and 53%, respectively. The prevalence of SCM was significantly higher (p<0.05) in exotic breeds of cattle and those kept under an extensive system of production. A total of 19 bacterial species were isolated with the majority being CNS (40.1%), S. aureus (15.8%) and Micrococcus spp. (10.4%). S. aureus isolates showed varied resistance to the tested antibiotics with the highest resistance being against ceftazidime (75%), amoxycillin (50%) and streptomycin (46.9%). Several S. aureus isolates were resistant to oxacillin (34.4%) and cefoxitin (12.5%). CNSs were more resistant against ceftazidime (79.1%), amoxycillin (34.6%) and oxacillin (32.1%). Majority (92%-100%) of the Staphylococcus spp. were highly sensitive to ciprofloxacin a fluoroquinolone and augmentin. The high prevalence of SCM and bacteria resistant to antibiotics shows a need for animal health professionals and farmers to develop strategies for the management of mastitis and antibiotic resistance in dairy cows in the study area.

Constraining the Lithospheric Discontinuity Structure Beneath Hawaiʻi Using Teleseismic Receiver Functions

AbstractThe Hawaiian Islands represent the youngest portion of the long‐lived Hawaiian‐Emperor Seamount chain sourced from hotspot volcanism on the northwesterly moving Pacific plate. Despite being one of the best studied hotspots on Earth, our understanding of the lithospheric discontinuity structure of Hawaiʻi is inhibited by a lack of a long‐term distributed broadband seismic network and lithospheric‐scale imaging of other oceanic hotspots. In this study, we analyze 3,530 teleseismic waveforms from 1,130 events recorded at 47 stations to compute P‐wave radial receiver functions. We then incorporate an elevation correction to adaptive common conversion point stacking to create a 3D discontinuity volume of the lithospheric structure associated with an ocean island hotspot. We find a positive amplitude conversion consistently at ∼12 km below sea level, likely representing the crust‐mantle transition below much of the island. However, this conversion occurs at only ∼6 km below Kīlauea, where local tomography images a zone of high P‐wave velocities (&gt;7 km/s) within the crust and deformation of olivine phenocrysts within a magmatic reservoir is thought to occur. At this location, seismicity also extends vertically to 35 km depth before merging with an interpreted sill complex at ∼40 km. We interpret this anomalously shallow high amplitude discontinuity as an olivine‐dominated magmatic reservoir with an estimated maximum 5% melt over the resolution of our data at crustal depths. This represents the shallow seismic signature of a much more extensive magma system extending to depth. These images provide a better understanding of the magmatic structure associated with oceanic hotspot volcanoes.

Large Igneous Provinces and the Release of Thermogenic Volatiles from Sedimentary Basins

Large igneous provinces (LIPs) are characterized by flood basalts and extensive magmatic plumbing systems. When sills and dykes are emplaced in sedimentary basins, the heat released can result in extensive contact metamorphism and gas generation. During the past 20 years, this process has been highlighted as potentially playing a key role in terms of proposed links between LIPs and global environmental changes. The geochemistry of the sedimentary rocks that the magma intrudes, and their potential to generate thermogenic gases such as CO2 and CH4 during heating, are critical controlling factors.

Characterization, Production and Reproduction Performance of Southern Odisha Goats

Background: The native goat populations in southern Odisha viz. Narayanpatna, Malkangiri and Ganjam were characterized phenotypically in the present study. Ganjam goats stood apart from other populations due to their large, pointed horns and stature. Odisha state has 30 districts and 10 different agro-climatic zones. Methods: The present study area is under North Eastern ghat and Eastern ghat high land agro climatic zones. An extensive management system is used to raise all the goats with a flock size varying from 6 to 45. The body weight was recorded from birth to 12 months at an interval of 3 months. Result: The average adult body weight from these 3 goat populations was 17.39±0.20, 16.31±0.17, 16.39±0.20 kg for Ganjam, Malkangiri and Narayanpatna goats, respectively revealing that Ganjam goats were heavier than the other two populations. The average age at sexual maturity and kidding interval was recorded as 318.24±5.24 and 312.06±1.28 days, 236.76±6.23 and 223.21±0.88 days, 218.34±4.28 and 218.22±0.76 days for Ganjam, Narayanpatna and Malkangiri goats, respectively revealing that Ganjam goats had significantly higher estimates than other two types. Males of all goat types were found to have higher body weight than the female counterparts beyond 3 months of age and found to be conspicuous at later age. This information on the physical characterization and production potentials may be helpful in developing further breed improvement strategies and breed registration.

«Second economy» of U.S

Research examines multiple approaches to the term “second economy”, which appeared in the scientific economic community in the 70s of the XX century, and received a diametrically opposite interpretation already in the XXI century. The relevance of the topic is due to the scale of activities and the importance that the activities of American TNCs abroad, have acquired through an extensive and developed system of affiliated enterprises and foreign direct investment. The need to clarify the term “second economy” comes from the presence of many approaches to this concept, diametrically opposed to each other: in fact, there are two approaches, the first of which is based on the fact that the “second economy” or “economy number 2” is an informal, shadow, “gray” economy, the indicators of which are evaluative, and characterize illegal methods of enrichment or gaining access to benefits; the second approach is based on the fact that the “second economy” means a developed and extensive network of international production created through American direct investment - a complex of American enterprises abroad. The retrospective of the formation and development of TNCs and the filial system in the world economy, theoretical and practical approaches to the activities and especially the foreign economic expansion of monopolies during the XX century are considered in detail. The main attention in the work is paid to the peculiarities of the foreign activities of American TNCs and indicators reflecting their presence outside the national economy, so large that they form the “second economy” of the United States: the number of parent and affiliated enterprises, the geography of their presence and specialization, dynamics and other features of American enterprises are analyzed, investments abroad, as well as the impact of economic policy (tax and protectionism policy) on the volume of investment exports abroad.

Initial Experience with the Commercial Electron FLASH Research Extension

The purpose of this study was to introduce a new commercial electron FLASH system that has the potential to become widely available for FLASH researchers globally. In this study, we first present the initial acceptance and commissioning tests for the FLASH system, and second, we highlight preliminary FLASH effect results from our cell studies. A linear accelerator was converted into a commercial research platform with the FLASH Research Extension, enabling the generation of a powerful 16 MeV electron FLASH beam. The dosimetric and stability tests were conducted using various dosimeters (i.e., radiochromic film, optically stimulated luminescent dosimeters (OSLDs), and a plane-parallel ionization chamber). To evaluate the FLASH effect, normal and cancer cell lines were FLASH irradiated using different pulse repetition frequencies (PRF) of 18 pulses/s and 180 pulses/s. The electron FLASH mode was able to generate over 1 Gy per pulse at the isocenter and a dose rate of up to 690 Gy/s near the accessory mount of the Linac gantry head. The charge collected by the plane-parallel ionization chamber at the highest PRF (i.e., 180 pulses/s) showed a linear relationship with the delivered number of pulses (i.e., 1 to 99 pulses) with a coefficient of determination (R2) of 0.9996. The absorbed dose measured using radiochromic film and OSLDs agreed within 3%, on average, and followed an inverse square law as the source-to-axis distance (SAD) varied for which the R2 values were 0.9972 and 0.9955 for radiochromic film and OSLDs, respectively. The profile of the FLASH beam was symmetrical but was not as flat as the conventional 16 MeV electron beam due to the use of a thinner custom scattering foil to reduce the degradation of the ultra-high dose rate. The depth-dose curve beyond the build-up region for the FLASH beam was similar to the conventional 16 MeV electron beam for which the range at 50% the maximum dose (R50) agreed within 0.5 mm. The FLASH beam output remained consistent over a 4-month period with a variation of 2.5%, on average. The FLASH sparing effect was observed in vitro for healthy human pancreatic cells. Furthermore, we observed that the highest PRF beam (180 pulses/s) was more effective at destroying pancreatic cancerous cells while minimizing damage to healthy cells compared to the lowest PRF beam (18 pulses/s). The novel commercial FLASH Research Extension system was dosimetrically characterized for pre-clinical FLASH research, and preliminary in vitro results demonstrated the FLASH effect. Given the prevalence of linear accelerators, this new commercial system has the potential to greatly increase the access to FLASH research.

Dostęp do usług świadczonych w ogólnym interesie publicznym w zakresie publicznego transportu zbiorowego w przepisach Unii Europejskiej i prawa krajowego na przykładzie prawa polskiego

Services of general interest in the field of public transport are governed by an extensive system of laws, created by the European Union and national authorities. This is done on the basis of the division of competences between the Union and the Member States, pursuant to Article 4 of the Treaty on the Functioning of the European Union. It is therefore possible, on the one hand, for the Union to make a positive contribution to the development of services of general interest in the field of public transport by creating uniform standards; and, on the other, for the diversity of traditions, structures and situations in the individual Member States to be preserved through the law‑making activities of the national authorities. Using the example of Poland, it may be stated that the legal system relating to the provision of services of general interest in the field of public transport consists of regulations ranging from treaty provisions, through Article 36 of the Charter of Fundamental Rights and EU rules, to statutory regulations and local laws.

Investigating the cecal microbiota of broilers raised in extensive and intensive production systems.

Intensive broiler production practices are structured to prevent the introduction and spread of pathogens; however, they can potentially minimize the exposure of broilers to beneficial commensal bacteria. In this study, we used 16S rRNA amplicon sequencing to characterize the cecal microbiota of 35-day-old broilers from 22 independent commercial farms rearing broilers under intensive (IPS) or extensive production systems (EPS). We aimed to determine which bacteria are normal inhabitants of the broiler ceca and which bacteria might be missing from broilers in IPS. In addition, we generated a collection of 410 bacterial isolates, including 87 different species, to be used as a resource to further explore the effects of selected isolates on bird physiology and to elucidate the role of individual species within the cecal microbial community. Our results indicated significant differences in the microbiota of broilers between systems: the microbiota of broilers from EPS was dominated by Bacteroidetes {55.2% ± 8.9 [mean ± standard deviation (SD)]}, whereas Firmicutes dominated the microbiota of broilers from IPS (61.7% ± 14.4, mean ± SD). Bacterial taxa found to be core in the EPS microbiota, including Olsenella, Alistipes, Bacteroides, Barnesiella, Parabacteroides, Megamonas, and Parasutterella, were shown to be infrequent or absent from the IPS microbiota, and the EPS microbiota presented higher phylogenetic diversity and greater predicted functional potential than that of broilers in IPS. The bacteria shown to be depleted in broilers from IPS should be further investigated for their effects on bird physiology and potential application as next-generation probiotics. IMPORTANCE Production practices in intensive farming systems significantly reduce the introduction and spread of pathogens; however, they may potentially minimize the exposure of animals to beneficial commensal microorganisms. In this study, we identified core bacteria from the cecal microbiota of broilers raised in extensive production systems that are missing or reduced in birds from intensive systems, including Olsenella, Alistipes, Bacteroides, Barnesiella, Parabacteroides, Megamonas, and Parasutterella. Furthermore, the cecal microbiota of broilers from extensive systems showed higher diversity and greater functional potential than that of broilers from intensive systems. In addition, a collection of bacterial isolates containing 87 different species was generated from the current study, and this important resource can be used to further explore the role of selected commensal bacteria on the microbial community and bird physiology.

A Multilevel Model of Energy Market Considering Coupon Incentive Based Demand Response with Wind Power Uncertainty

Demand response (DR) can decrease or increase energy consumption and has the ability to use generating assets more efficiently. Because of the increased power consumption, it has become necessary for the power system networks either to update or upgrade the already existing power system or to inculcate some schemes to minimize the load through effective customer engagement. To address this issue incentive-based demand response proved to be an effective tool to change the pattern of consumption. This work proposes a novel multilevel energy market considering coupon incentive based DR (C-IBDR). The proposed model is operated on a modified PJM 5-Bus system where the independent service operator (ISO) using economic dispatch (ED) computes the localized marginal pricing (LMP) and the load serving entity (LSE) issues coupons to consumers and procures the demand reduction from them. Two wind generators are incorporated into the test system and their effect on the localized marginal pricing with and without demand response is analyzed. The optimization problems are modeled using particle swarm optimization (PSO) and linear programming (LP) in MATLAB. The results demonstrate that the proposed C-IBDR reduces peak demand from 900 to 860 MW through the utilization of wind and DR. This alteration modifies the load curve, increases the power factor from 0.524 to 0.555, raises the revenue of LSEs from $106,646 to $106,946, reduces generation costs from $473,291 to $214,651, and procures a total of 262 MW of demand from the consumer side in the form of demand reduction. The system is further tested for scalability. The practicality of the suggested approach in handling more extensive systems is vividly demonstrated through its application to the modified IEEE 118-bus system.

Service Recommendation of Industrial Software Components Based on Explicit and Implicit Higher-Order Feature Interactions and Attentional Factorization Machines

In the context of the rapid advancement of the Industrial Internet and Urban Internet, a crucial trend is emerging in the realization of unified, service-oriented, and componentized encapsulation of IT and OT heterogeneous entities underpinned by a service-oriented architecture. This is pivotal for achieving componentized construction and development of extensive industrial software systems. In addressing the diverse demands of application tasks, the efficient and precise recommendation of service components has emerged as a pivotal concern. Existing recommendation models either focus solely on low-order interactions or emphasize high-order interactions, disregarding the distinction between implicit and explicit aspects within high-order interactions as well as the integration of high-order and low-order interactions. This oversight leads to subpar accuracy in recommendations. Real-world data exhibit intricate structures and nonlinearity. In practical applications, different interaction components exhibit varying predictive capabilities. Therefore, in this paper we propose an EIAFM model that fuses explicit and implicit higher-order feature interactions and introduce an attention mechanism to identify which low-level feature interactions contribute more significantly to the prediction results. This approach leads to increased interpretability, combining both generalization and memory capabilities. Through comprehensive experiments on authentic datasets that align with the characteristics of the Service Recommendation of Industrial Software Components problem, we demonstrate that the EIAFM model excels compared to other cutting-edge models in terms of recommendation effectiveness, with the evaluation metrics for the AUC and log-loss reaching values of 0.9281 and 0.3476, respectively.
