The integrated and indivisible nature of the SDGs is facing implementation challenges due to the silo approaches. We present the three interconnected foci (SDG interactions, modeling, and tools) at the science-policy interface to address these challenges. Accounting for them will support accelerated SDG progress, operationalizing the integration and indivisibility principles. [ABSTRACT FROM AUTHOR]

This paper analyzes the process of reordering and intensification associated with the Spanish cereal sector, which began in 1937 under Franco's regime. Considering the process as a practice of design and spatial re-planning of the territory, the first stage focuses on the reordering of the sector through an intense state interventionism in the processes of production, distribution, and consumption of cereals. The second stage, framed in a context of significant economic development in the country encouraged by the international context, focuses on the adoption of multiple measures for the intensification of production. Approached from an anthropic perspective of instrumentalisation of the natural environment, this process would lead to the reconfiguration of the structure of operations and to the alteration of part of the biophysical and sociocultural components of the sector.

Healthcare organizations often confront multiple institutional logics that reinforce professional and departmental hierarchies and silos. Research in the field focuses on how professionals navigate such tensions through everyday practices that maintain, reinterpret or shift specific logics. In this paper, we take a practice perspective to explore the mediating capacity of values-driven practices as a bridge between different logics. Drawing on insights from a leadership programme delivered to 70 public healthcare staff across seven hospitals in South Africa, we argue that articulating values conflicts and shared values shape relational practices, which mitigate the pressures of hierarchy and conflicting logics.

Italy built its ammasso silo network in the 1930s for two purposes: to stockpile grain and to symbolize fascist power. Much of the network was destroyed in World War II, and over half of the silos still standing are now disused and in disrepair. These structures should be protected and refurbished because they are part of Italy's historic and agro-industrial heritage and because reusing existing buildings instead of constructing new ones reduces the carbon footprint. To evaluate silo repurposing potential, a method developed for inventorying Spanish silos was adapted and applied to the 30 remaining ammasso silos. The method explores the general features, construction, equipment, and socioeconomic environment of each silo. All extant ammasso silos have machinery for receiving, storing, and dispatching grain, and most have equipment for cleaning, sorting, weighing, and packaging. Vertical-cell silos are challenging to convert, unlike horizontally-oriented silos and other open-plan agro-industrial buildings. Even so, some have already been made over into shops, leisure areas, museums, and even homes. Examples of silo reuse in other countries, such as Spain and Portugal, can offer further useful insights. However, socio-economic indicators suggest that silo repurposing projects are viable only in large population centres. [ABSTRACT FROM AUTHOR]

The current work aimed to evaluate the effect of ensiling density on the fermentation quality and aerobic stability of Pennisetum giganteum silages. The silage was ensiled in laboratory silos (1 L), and three treatments were designed according to different ensiling densities: (1) low density (LD, 750 kg/m3); (2) medium density (MD, 900 kg/m3); and (3) high density (HD, 1050 kg/m3). During ensiling, the silage was sampled for a fermentation quality analysis. All silages were well preserved, as indicated by the high lactic acid (LA) content and low pH (<4.2). The MD treatment had the highest acetic acid content (24.9 g/kg dry matter) and the HD treatment had the lowest ammonia nitrogen (NH3-N) content (68.2 g/kg total nitrogen, TN) among all silages after 45 days of ensiling. The aerobic stability of HD, MD, and LD persisted for 51 h, 54 h, and 48 h, respectively. The NH3-N contents of HD and MD were below 80 g/kg TN during aerobic exposure. These results show that the increase in ensiling density improved the fermentation quality and aerobic stability of Pennisetum giganteum silages. [ABSTRACT FROM AUTHOR]

Students who require intensive individualized intervention often demonstrate needs in both academic and behavioral domains. However, practices around assessment and development of interventions are often siloed and separate, which can be a barrier to implementing intensive individualized support in an integrated manner to maximize efficiency. In this article, we provide a blueprint for educators to work collaboratively to complete an integrated assessment that can lead to developing a truly integrated individualized intervention. We also share a vignette demonstrating how team members might create a team to complete an integrated assessment and create a corresponding intervention plan. [ABSTRACT FROM AUTHOR]

This paper introduces to an international audience the 'encyclopaedic approach' to geographical historiography. This approach was developed at the Free University of Amsterdam between 1961 and 1987 by Marcus Heslinga and Andries Kouwenhoven. Signalling how contemporary geography is hampered by the silofication of different subdisciplines and how a better understanding of our shared and pluriform histories can help overcome these silos, the encyclopaedic approach demonstrates how an 'engaged pluralist' historiography of geography could take shape. Testifying to its bridge-building character, the approach was developed in response to decades of acerbic conflict between rivalling schools of human geography in the Netherlands. Its central premises involve an acknowledgement that geography is a dynamic discipline with shifting formal and material objects and an empirical strategy to map and relate these different conceptual fields. • Chronicles the encyclopaedic approach to the history of human geography developed by Marcus Heslinga and Andries Kouwenhoven. • Situates the emergence of the engaged pluralist encyclopaedic approach in the history of Dutch human geography. • Discusses how the encyclopaedic approach inspiresto overcome the silofication and fragmentation of contemporary geography.

Summary: The columned‐supported reinforced concrete silo models with different filling conditions considering soil‐structure dynamic interaction (SSI) are established based on the finite element program ANSYS to thoroughly investigate the complex interaction mechanism of the soil–pile–silo structure with granular solid. The dynamic characteristics and seismic responses of the SSI system and fixed‐base condition are analyzed and compared when the filling conditions are empty‐filled state, half‐filled state and full‐filled state. The numerical results reveal that the SSI effect reduces the seismic acceleration response of columned‐supported silos effectively. However, in terms of displacement, the SSI effect often amplifies the relative deformation of the supporting column and the cylindrical silos. Furthermore, the SSI effect often increases the relative dynamic lateral pressure of the storage material in the half‐filled silo condition. In the full‐filled silo condition, the relative dynamic lateral pressure at the top and bottom of the storage material is increased by the SSI effect; while it is decreased in the middle part of the granular solid, demonstrating that the SSI effect could change and increase the seismic responses of the silo structure in certain areas. Therefore, the investigation provides a comprehensive insight into the interaction mechanism of the pile–soil–silo structure with different filling conditions. [ABSTRACT FROM AUTHOR]

This study aims to investigate the impact of gravity material density on wall pressure and flow patterns during silo discharge using indoor tests and numerical simulations. A self-developed semi-cylindrical flat-bottomed circular silo was utilized in the indoor tests. The custom pressure sensors were embedded in the silo walls to measure the wall pressure. The cameras were used to record the evolution of flow patterns. Two types of gravity materials were selected with different densities and an average particle size of 5.5 mm: ceramic balls (referred to as ceramic particles) and soybeans. Five discharge tests were then conducted on each material. Subsequently, discrete element (DEM) numerical simulations were performed to supplement the test observations. The experimental and numerical simulations were combined to explore the effects of gravity material density on the flow pattern and wall pressure. The results reveal that there was a similar flow evolution of ceramic particles and soybeans, indicating the transitions from the mass, funnel, and mixed flow to the tubular flow. There was a dynamic variation in the boundary between the flowing and stationary zones during discharge. The boundary of the stationary zone remained stable at the early and middle stages of discharge, with an angle of 54.03° and a height of 0.310 m. In the late stage of discharge, the flowing boundary on the surface of the gravity material was intersected with the stationary zone boundary at an angle of 28.5°, ultimately forming a "detention zone" near the bottom of the silo with an angle of 28.5° and a height of 0.120 m. The density of the gravity material then dominated the fluctuation of wall pressure. The materials with the higher gravity density caused the more intense variations in the pressure on the silo wall. Among them, the ceramic particles shared a greater pressure amplitude than the soybeans. There was no influence of gravity material density on the location of the peak lateral pressure. The peak points of lateral pressure for both ceramic particles and soybeans were located at approximately 3/10 of the silo wall height from the bottom. During the initial discharge (the first 5 s, accounting for 1.43% of the total discharge duration), there was a sharp increase in the wall pressure of ceramic particles and soybeans, with peak increments of 263% for ceramic particles and 257% for soybeans. At the very beginning of the discharge, the wall pressure increased rapidly in a very short time, inevitably causing an impact on the silo wall. This test verified that the silo failures frequently occurred at the beginning of discharge in the practical scenarios. According to the evolution of the mesoscopic force chain during discharge, the ceramic particles with the higher gravity density exerted greater pressure on the silo wall via the force chain network. The fluctuation of wall pressure was directly related to the breaking, reformation, and arching of the force chains. Furthermore, there was a direct connection between the transmission of the mesoscopic force chain network, force chain rupture, and reformation, as well as the macroscopic distribution of wall pressure. These findings can provide theoretical support and test evidence for the optimal design and safe operation of silo structures. The insights can be gained to mitigate the risks for the high efficiency in the structural integrity of silos during material handling. [ABSTRACT FROM AUTHOR]

The semi‐underground double‐storey squat silo (SUDSSS) is a new type of silo with the advantages of preserving grain quality. In this paper, a numerical model of SUDSSS was constructed using solid elements. The proposed numerical model was validated by test results of an experimental underground silo, and the results demonstrated that: (1) Before and after backfilling, the radial and circumferential stress of the underground storey reached their maximum at 2/3 from the bottom and 2/3 from the ground surface, respectively; (2) As the height of grain storage increases, the silo wall stress in the overground storey increases. From the top of the underground storey up to 1/4 height of the overground storey, the stress of silo wall increases. (3) For the underground storey, the maximum stress occurs at 1/3 of the way from the apex of bottom cone. Practical applications: The semi‐underground double‐storey squat silo is a new grain storage device proposed by this paper, which consists of two layers. The lower layer is located in the ground and can utilize the shallow ground temperature to realize the green and low‐temperature storage of grain, the upper layer is conducive to the turnover of grain, which can ensure the quality of grain storage. The new silo has the advantages of saving land, energy saving and carbon reduction. Based on the silo, this paper investigates the stress–strain properties of the silo before and after soil backfilling during the construction stage, and obtains the change pattern of the static mechanical properties of the silo. This paper analyses the mechanical properties of semi‐underground double‐storey squat silo under different storage conditions at the grain storage stage, and studies the change patterns of the mechanical properties of the silo body under different storage heights.

Natural phenomena and scientific issues are intrinsically interdisciplinary. Students need to study a variety of academic disciplines in the natural sciences to explain a phenomenon or its related problems. Our goal in the current study was to examine the epistemological foundation of students' interdisciplinary understanding of carbon cycling using the supervised latent Dirichlet allocation model. The 454 students in this study were from a public high school and a public research university in Texas. The students' interdisciplinary understanding was shown in each of the constructed response items. In the relationship between the proportion of interdisciplinarity in students' answers to the constructed response items and students' scores on interdisciplinary understanding, all integrations of disciplines were statistically significant in explaining students' interdisciplinary understanding. Moreover, one particular integration set had advantages for obtaining a high score. We found that science coursework contributed to students' interdisciplinary understanding in different ways, and this interdisciplinary understanding was influenced by the number and type of science courses taken. Characterizing interdisciplinarity based on the clusters of science disciplines provided insights into how students synthesize their knowledge. The significance of this study lies in its potential impact on diverse curricular and instructional approaches in interdisciplinary science education. [ABSTRACT FROM AUTHOR]

The influence of silo width on dense granular flow in a two‐dimensional silo is investigated through experiments and simulations. Though the flow rate remains stable for larger silo widths, a slight reduction in silo width results in a significant increase in flow rate for smaller silo widths. Both Beverloo's and Janda's formula accurately capture the relationship between the flow rate and outlet size. Flow characteristics in the regions near the outlet exhibit local self‐similarity, supporting Beverloo and Janda's principles. Moreover, global self‐similarity is analyzed, indicated by the transition in flow state from mass flow in regions far from the outlet to funnel flow near the outlet. The earlier occurrence of this transition favors to enhance the grain velocity and consequently increases the dense flow rate. An exponential scaling law is proposed to describe the dependencies of flow rate, grain velocity, and transition height on silo width. [ABSTRACT FROM AUTHOR]

Problem: HRD and HRM can sometimes operate in silos or at cross-purposes. The increasingly FRAGILE world order confronting business (i.e., Fragmenting boundaries; Resurgent populism; Accelerated digitalisation; Growing inequality; Inverted populations; Loss of Trust; and the Ecological crisis) mandates greater collaborative engagement across HRD and HRM. Solution: Following a detailed review of the skills-based implications of the FRAGILE world order, the article unpacks the nascent skills-based agenda, detailing the transition from traditional job to task-based understanding, and outlining some examples of what it can look like in practice. Ultimately, to effectively navigate the FRAGILE world order organizations must have a clear understanding of both their current skill demands and deficiencies, and equally skills required of the future. Stakeholders: This conceptual article will be of interest to HRD and HRM professionals, but equally hold broader insights for organizations and policy makers engaged in navigating the FRAGILE world order through a skills-based agenda.

The current investigation delved into the seismic analysis, design intricacies, and assessment of the response of elevated steel containment tanks when supported by concentrically braced frames. The primary focus was placed on comprehending the behavior of the supporting structure, recognizing its heightened vulnerability to damage under horizontal excitation—insights gleaned from reconnaissance teams studying earthquake aftermaths worldwide. A specific case study unfolded featuring a steel concentrically braced frame as the supporting structure, aligning with prevalent industry norms. Throughout the entire process, spanning design phases, seismic vulnerability assessments, and response evaluations, special emphasis was placed on the internal fluid sloshing phenomena. This nuanced consideration plays a pivotal role in shaping the dynamic response of the system. The study introduces two distinct design methods: the first method aligns with relevant international codes, while the second method innovatively incorporates the compressive strength of the braces into its approach. To evaluate the dynamic response of the elevated tank, both linear and nonlinear advanced analyses were employed. The comparative analysis of various strategies underscores the impact of the chosen design methodology on the overall system response. This multifaceted exploration aims to contribute valuable insights to the seismic resilience and design optimization of elevated steel containment tanks, furthering the understanding of their performance under seismic forces.

In this work, a numerical study of the effects of soil-structure interaction (SSI) and granular material-structure interaction (GSI) on the nonlinear response and seismic capacity of flat-bottomed storage silos is conducted. A series of incremental dynamic analyses (IDA) are performed on a case of large reinforced concrete silo using 10 seismic recordings. The IDA results are given by two average IDA capacity curves, which are represented, as well as the seismic capacity of the studied structure, with and without a consideration of the SSI while accounting for the effect of GSI. These curves are used to quantify and evaluate the damage of the studied silo by utilizing two damage indices, one based on dissipated energy and the other on displacement and dissipated energy. The cumulative energy dissipation curves obtained by the average IDA capacity curves with and without SSI are presented as a function of the base shear, and these curves allow one to obtain the two critical points and the different limit states of the structure. It is observed that the SSI and GSI significantly influence the seismic response and capacity of the studied structure, particularly at higher levels of PGA. Moreover, the effect of the SSI reduces the damage index of the studied structure by 4%. [ABSTRACT FROM AUTHOR]

We present an experimental investigation on the flow and clogging of bi-disperse mixtures of coarse and fine grains of different densities passing through small orifices. We vary the density ratio (coarse/fine) from 1.87 down to 0.79 by using amaranth seeds, glass and ceramic beads of similar size as the fine species in combination with 2.0 mm glass beads as the coarse grains. We analyzed the effect of the density ratio on the effective flow rate of the coarse species, the segregation during flow and the clogging for a range of orifice diameters. As in previous studies, the flow of the coarse grains is facilitated by the fine species, which prevents clogging. We show that the effective flow rate of the coarse species is virtually independent of the density ratio. These results suggest that in practical applications with the goal of clogging reduction, the density of the fine species used to ease the flow is not a relevant parameter and can be selected based on practical or economic constraints.

To investigate the development of cracks in the walls of reinforced concrete silos under feeding–discharge cycle loading, their causes, and their fatigue life during dynamic loading, a study was conducted using a combination of in situ monitoring and numerical simulation analysis. The following conclusions were drawn: during the loading and unloading process of the silo, the time of occurrence of the minimum pressure points follows a 4:3 ratio; extreme points are approximately 15 min apart; the minimum pressure increases during material addition and decreases during material subtraction; and the load in the non-discharge area is 1.43 times that of the load in the discharge area. That is, at the same elevation, the load borne by the silo wall is uneven, with fluctuations and rotational effects occurring. Under such uneven load conditions, the silo wall experiences significant bending and torsional moments, causing excessive local tension and leading to cracking. Our analysis showed that the most unfavorable load condition occurs when discharge ports 5 and 7 are operating simultaneously, which causes the maximum tensile damage to the silo wall. For the first time, a fatigue life prediction model for reinforced concrete silos was proposed, and the accuracy of this prediction method was verified based on actual conditions.

The purpose is to study seismic response and dynamic lateral pressure of the silo wall with different storage conditions under the earthquake. FEM was used to conduct dynamic time history analysis of the silo. The seismic response of the empty silo was smaller than that of the filled silos, and for the latter, under seismic action, the bulk sand particles and the silo wall had a more complex dynamic interaction, and nodes displacements on the wall and columns mainly fluctuated rising. For the deformation of the bulk sand, it was similar to a parabolic pattern in section, the closer to the silo center the greater the deformation was, and the farther away from the silo center the smaller the deformation was. The maximum acceleration was near the top of the wall in the empty silo, near the middle of the wall in contact with bulk sand in the filled silos. Nodes maximum overpressure coefficient was 1.6 and 2.9 in half fully and fully filled silos, respectively, but the coefficient 2.9 was greater than the standardized value of 2.0, therefore, the suggested overpressure coefficient was proposed. Meanwhile, Mises stress was investigated, and it was smaller in the empty silo, but larger in the filled silos, particularly in and around the ring beam due to the dynamic interaction between the sand and the silo wall, where the stiffness had a sudden change, and the maximum stress at the ring beam increased gradually with the seismic action.

The Beirut port explosion on August 4, 2020, caused extensive destruction and significant casualties, prompting inquiries into its scale and impact on neighboring structures. Speculation arose regarding the role of the nearby port silos in shielding western Beirut from the blast. This study leverages insights from previous research and uses a tailored blast wave propagation model to settle the debate on the silos' effectiveness in mitigating blast impacts. The analysis challenges prevailing notions: firstly, that the silos offered substantial protection, and secondly, the assumption linking the transient "window" phenomenon in the Wilson cloud to a similar opening in the preceding pressure front. Contrary to expectation, the pressure at the shock front remains continuous, albeit lower on the leeward side behind the silos. Downstream lateral regions experience pressure amplification due to the constructive interference of waves diffracted around the silos, with significant attenuation observed close (10 m) behind them—approximately 12%, 58%, and 2% of free-air values for overpressure, specific impulse, and specific energy, respectively. However, this shielding effect diminishes with distance, with the blast wave intensity largely restored at 450 m. Consequently, the silos' shadowing effect was limited to nearby port structures and part of the Lebanese navy base, which still incurred severe damage. The lesser impact on western Beirut is attributed to its greater distance from the explosion rather than the silos' protective influence. These findings suggest a reevaluation of urban disaster mitigation strategies, emphasizing geographical positioning over structural barriers and advocating for a holistic approach to urban resilience.

Flour mills are one of the workplaces with occupational health hazards due to irregular workplaces and environments where insufficient attention is paid to workers' safety. In this context, considering the extent of difficulties faced by workers in flour mills, hazards and risks that could affect the health and occupational safety of workers were investigated in a sample of flour mills in Iğdır province. The data obtained as a result of the research was ranked using the matrix method. The study identified 68 specific risks, of which 38% were identified as unacceptable risks requiring immediate action and 33% as risks requiring medium-term action. The results show that among the factors negatively affecting the health of workers, the respiratory hazard level of wheat dust with RS:15 (l:3, s:5) and the explosion hazard with RS:20 (l:4, s:5) occupy significant positions. Despite the emphasis on the importance of hygiene standards, serious deficiencies were identified, such as RS:20, which is considered high risk. In addition, the presence of many machines, such as conveyors, silos, compressors and rollers, was found to increase the risks on the system in the range of RS:20-25, which could lead to serious injury or death. Bacteria and microorganisms, such as RS:16-18, proliferate due to the low availability of personal hygiene facilities in the factory. For each identified risk, the necessary control measures are proposed and it is emphasized that protective measures should also be taken even after the implementation of these measures. Among the factors that negatively affect the health of workers in flour mills are the lack of use of personal protective equipment, working in dirty conditions, the presence of elements that can cause respiratory problems, as well as injuries related to carrying heavy loads on slippery floors and using unprotected machinery.

This study on the state of financial research analysed the citations made in leading business and economics journals in the period 1997–2020. It found that, contrary to other business fields, and despite citing more references, finance researchers overlooked the fruitful mode of knowledge creation by integrating advances from disciplines other than economics. Additionally, citations in economics became disproportionate to older papers. Furthermore, intradisciplinary citations remained predominantly in the same four journals, although others became prominent. These findings on the state of financial research supplement other issues inhibiting finance knowledge progression and have inferences regarding the training of future scholars.

To address the problems of poor interactivity and reliance on experience in decision-making during the aerobic fermentation process of cow dung, a fermentation process monitoring system based on digital twin technology was designed. Firstly, a digital twin virtual model of the fermentation chamber was constructed using the Unity engine, and the scene environment and virtual interface were designed and built. Secondly, the IoT gateway and database were designed for transmitting and storing twin data. Finally, a simulation platform was built to conduct time-series synchronization and collision detection experiments on the digital twin system. The experimental results show that the designed digital twin monitoring system virtual model of the fermentation silo has high synchronization with the physical object, which can achieve the virtual and real synchronization, and verifies the feasibility of the system.

Over the past two decades, the silo bag system has gained popularity for storing grains and by-products under hermetic conditions. However, the impact of higher temperatures in the outer grain layer on key industrial parameters, such as wheat baking quality, remains insufficiently understood. Traditional silo bags are black on the inside and white on the outside to reflect sunlight, but colored bags, recently introduced to the market, absorb more heat, potentially warming the grain and causing damage. This study aimed to assess the effect of grain strata and bag color on grain temperature and quality under field conditions. Results showed a significant surface temperature increase in colored bags compared to white ones, approximately 3 °C, which affected the temperature of the peripheral grain layer. Moisture content slightly increased (0.2 percentage points) in the outer grain layer. However, many industrial quality parameters (protein content, P/L, W, and loaf volume) and the germination test for wheat, showed no significant differences between colored and white bags or between different strata after 120 days of storage, although the falling number increased and wet gluten decreased. These findings suggest that, despite surface temperature differences, the overall industrial quality of wheat remains unaffected by external bag coloration. The influence of ambient temperature on the peripheral layer was estimated to affect approximately 5–10% of the grain mass, indicating that adverse impacts on grain quality may go unnoticed without implementing stratified sampling techniques.

This study was conducted to evaluate the ensiling characteristics of maize–forage legume mixtures in small-scale silos. Sole and intercrops forage materials were harvested 80 days after planting and ensiled in small-scale silos, that is: plastic bags, plastic drums, and small pits, for 60 days. After ensiling, samples were collected to examine the chemical composition, microbial community and fermentation quality. Mixed silages stored in the drum silos had significantly (p ≤ 0.05) higher DM content (35.69%) than that from pit and bag silos. The drum silos had significantly (p ≤ 0.05) higher crude protein concentration (20.57% DM) in sole legume silages than other silo types. Neutral detergent fibre concentration (39.76% DM) of sole forage silages was greatest in bag silos than in other silos. High in vitro dry matter digestibility and water-soluble carbohydrate values (58.15 and 12.19% DM respectively) for mixed silages were recorded in drum silos. Bag silos showed lower numbers of lactic acid bacteria and higher populations of enterobacteria (4.86 and 4.26 log10 CFU g−1 respectively) in sole forage silages than other silos. Mixed silages ensiled in drum silos produced significantly lower (p ≤ 0.05) pH (3.03) and ammonia nitrogen content (3.73% TN) compared to pit and bag silos. The study concluded that ensiling maize–forage legume mixtures in drum silos can have a positive effect on the nutritive value of ruminants' feeds. Therefore, the recommended forage type for ensiling is mixed silages. [ABSTRACT FROM AUTHOR]

Alternative grading strategies are increasingly popular in higher education, but research into the outcomes of these strategies is limited. This scoping review aims to provide an overview of the relevant research regarding alternative grading strategies in undergraduate STEM and identify gaps in the literature to inform future research. This scoping review was done using the stages as described by Arksey and O'Malley (Int J Soc Res Methodol 8(1):19–32, 2005). The results of this review indicate there is a lack of consensus on the theoretical foundation for the benefits of alternative grading and, therefore, limited validated tools being used to capture these benefits. Additionally, we find that research into alternative grading methods tends to occur in both disciplinary and practice-based silos. [ABSTRACT FROM AUTHOR]

We investigated the clogging behavior observed during the flow of aspherical particles from a silo in the presence of spherical particles of different sizes and proportions using flow visualization experiments and discrete element method simulations. The size of the avalanche, essentially the tendency of clogging, exhibits non-monotonic dependence on the spherical particle volume fraction. For small enough content of spherical particles, the clogging tendency intensifies, whereas it reduces rapidly for high enough spherical particle fractions, with a minimum in between. The non-monotonic behavior is observed to persist over for different spherical particle sizes. The overall behavior is shown to arise due to competing effects between the localized total particle fraction influencing avalanche strength and mean size of the particles exiting the silo, influencing the probability of arch formation.

Objectives: The central objective of this paper is to propose and test a model for the development of network governance structures to respond to the silo effect in the innovation management process in a large research organization. Method: A case study was used with the objective of building a governance model that could address the problems derived from the silo effect. To achieve the objective, validation workshops were held, with teams being challenged to reflect on the mechanisms and basic rules used to assemble the model. Results: The efforts made to inhibit the silo effect in the organization investigated were successful. Internal events were held to exchange knowledge between research centers, which resulted in greater stimulation of connections between these and other actors throughout the innovation ecosystem. Conclusions: The governance model adopted to mitigate the problems derived from the silo effect proved to be effective in promoting interaction between research centers on issues related to open innovation. The model, supported by mechanisms and basic rules inserted in the key actions, proved to be efficient in promoting a more intense relationship between the research units of the institution studied, resulting in new network actions.

Mycotoxins are toxins produced by various types of fungi, including Fusarium, which can produce different types of mycotoxins, such as Deoxynivalenol (DON), Zearalenone, T-2 toxin, and Fumonisins (FUM). Mycotoxins have the potential to reduce the quality of crops and pose health risks to both humans and animals. This can result in reduced animal production and substantial economic consequences on a global scale. Extensive research has been carried out to investigate the high incidence of contamination in grains by Fusarium fungi. In this study, 80 samples of maize from silos of dairy farms in Fars province, Iran were collected and examined for fungal contamination by Fusarium and potential production of DON and FUM. For this purpose, identification using specific primers for different genes was carried out by polymerase chain reaction test and gel electrophoresis with agarose (1%). Among different counties, the silos in Kharameh with 47.05% and Jahrom with 46.15% had the highest contamination rates, and the lowest contamination rate belonged to Kazeroon with 27.27%. Out of the 30 positive samples contaminated by Fusarium, 21 produced FUM, 4 produced DON, and 5 produced both toxins. Fusarium species that contaminated the maize samples were also identified, including 13, 10, and 7 samples contaminated by F. proliferatum, F. verticillioides, and F. graminearum, respectively. As a conclusion, the findings of the study indicated that 37.5% of the corn samples from dairy farm silos in Fars province were contaminated with the Fusarium fungus, which had the potential to produce the toxic mycotoxins, deoxynivalenol, and fumonisins.

ABSTRACT Mathematical models to determine external pressure coefficients (Cpe) in conical silo roofs are scarce in silo design standards and scientific papers. These coefficients are dimensionless and are influenced by Reynolds number, air viscosity, geometry, and surface roughness of the material used in the structure. Pressure coefficients in conical roofs vary in the circumferential and meridional directions. Cpe values are essential in designing these structures to determine the pressures that arise from wind action. However, the scarcity of mathematical models for calculating external pressure coefficients in conical silo roofs made us conduct harmonic regression analyses to fit mathematical models based on experimental data developed in wind tunnels. Model fitting to experimental data had coefficients of variation lower than 10% in 87.5% (7/8) of the analyzed levels. These models are recommended for cases where wind gust duration does not exceed 3 seconds.

Abstract The research main purpose is to realize a short-term forecast temperature values inside metal soybean storage silos using the variables temperature and relative humidity, to predict and analyze the impulse response using vector autoregressions (VAR) with the Seemingly estimator. Unrelated Regression (SUR). The soybean storage silo is considered a multivariate system, as inside the metallic structure there are several temperature and relative humidity sensors, both located internally and externally. As a multivariate system, equations were adjusted using the vector autoregressive methodology, to capture external shocks and their influence on each variable and, determine how long this impact will take effect on the system. The forecast and response impulse show in advance the moment in which that the aeration process must be started. The system of equations points out that the prototype's external variables represented by temperature 7 (T7) and humidity (U7) directly influence other variables. After the occurrence of an external shock, endogenous variables take 4 periods of time to stabilize. An external action, whether naturally or through aeration, will take around eight hours to have an effective change in temperature and humidity. The forecast provides advance knowledge to carry out aeration in the silo, in order to keep the temperature and relative humidity controlled. As 6 periods of time are needed for the response to be carried out, ranging from hours to 12 hours, given that the observations were collected every 2 hours, this time was necessary to stabilize the variables. Keep these variables at target values to add commercial value to the product.

Abstract This study proposes a modification for the current design approach for square and rectangular silos that accounts for silos’ wall flexibility. First, the authors investigated the effect of wall stiffness symbolized by the wall width-to-thickness ratio (a/t) and silo’s dimensions, on the wall-filling pressure using a recently validated 3D finite element model (FEM). The model was then employed to predict the pressures acting on silos’ walls accounting for the stress state in stored granular materials. Most design formulas and guidelines assume silos’ walls to be rigid. This assumption is acceptable for the case of rigid wall concrete silos; however, it is questionable for semi-rigid, flexible wall metal silos. Consequentially, it is crucial to determine the minimum wall stiffness necessary to secure the applicability of the current design rigid wall assumptions and to propose a way to deal with semi-rigid and flexible walls. To this end, several wall pressure distributions that correspond to filling steel silos with varied wall thicknesses were studied. A new adjustment to the Janssen technique was proposed for a better estimate of the wall-filling pressures for square and rectangular silos. In the case of prismatic silos, the Eurocode uses the Janssen equation together with an equivalent radius of a corresponding circular silo (with the same hydraulic radius) to determine the wall pressure. This method predicts pressure values that are practically accurate for rigid-wall silos, but its accuracy decreases for semi-rigid and flexible-wall silos. As an enhancement, the Janssen equation was modified in this research to generate more accurate pressure estimates based on the equivalent volume concept. The finite element results of several developed models with the same granular material were compared to the estimations of the newly established approach to verify the broad range of its applicability.

This study was focused on the analysis of the emission of volatile compounds as an indicator of changes in the quality degradation of corn groats with 14% and 17% moisture content (wet basis) using an electronic nose (Agrinose) at changing vertical pressure values. The corn groats were used in this study in an unconsolidated state of 0 kPa (the upper free layer of bulk material in the silo) and under a consolidation pressure of 40 kPa (approximately 3 m from the upper layer towards the bottom of the silo) and 80 kPa (approximately 6 m from the upper layer towards the bottom of the silo). The consolidation pressures corresponded to the vertical pressures acting on the layers of the bulk material bed in medium-slender and low silos. Chromatographic determinations of volatile organic compounds were performed as reference tests. The investigations confirmed the correlation of the electronic nose response with the quality degradation of the groats as a function of storage time. An important conclusion supported by the research results is that, based on the determined levels of intensity of volatile compound emission, the electronic nose is able to distinguish the individual layers of the bulk material bed undergoing different degrees of quality degradation.

A fundamental open problem in the mechanics of granular media is the determination of the stress in the static state. It is known that the static stress depends strongly on how the grain assembly is created and the nature of confining boundaries. Non-trivial spatial variations have been observed even in simple geometries, posing long-standing challenges to continuum modelling. In this paper, we create gravity-deposited grain packings computationally and devise a method to visualise the paths of load transmission, which we call force lines. We show that the force lines reflect the flow during deposition, thereby encoding preparation history. We then show that the force lines coincide with ensemble averaged biased random walks in the particle contact network; this identification yields a closure relation for the stress, which together with the static momentum balances fully determines the stress field. The model makes accurate predictions for the stress in piles and silos, even for unusual deposition methods, thereby showing promise for more general scenarios. [ABSTRACT FROM AUTHOR]

As an anthropologist currently working in the policy realm, I provide insights on the value of anthropology and its potential for growth and impact, both within and beyond academia. Drawing from my experiences studying in graduate school, teaching in academia, and holding nonacademic jobs, I suggest that anthropology can flourish by breaking free from disciplinary boundaries and silos, challenging conventional notions of scholarship, and by "studying in." The next 50 years of anthropology can be brighter, more inclusive, and more accessible if the discipline's practitioners think more critically about how we do our research and who we share our research with, what we frame as research and scholarship, and how we train and support the next generation of anthropologists.

Large silo shell grids are used in a large number of coal storage sheds in power plants and other industries, where holes are cut in the ends as required by the process. Numerical wind tunnel analysis for the static wind effects of these semi-open structures are carried out by using the wind engineering calculation function of FLUENT. Based on the secondary development of the STADS and FLUENT interface program, the model conversion and the automatic reading and loading of wind pressure are completed through menu operation and parameter control, and the running speed of the program is optimized. With a dry coal shed in Bangladesh with an open upper section and a steel mill in India with an open lower section as research subjects, the wind pressure coefficients and wind speed vectors for different wind angles are given considering the combined effect of internal and external wind pressure. According to the wind pressure distribution law and the wind pressure similar partitioning criterion, the internal and external wind pressure partitioning body type coefficients of the upper and lower semi-open silo shell grids are provided, and the calculation results can be provided as reference for the structural design of similar structural projects.

Taking the silo shell structure as the research object, STADS, aided design software for grid structure, was applied to study its reinforcement design application using cable members. Firstly, considering that the structure has been built, it is mainly reflected in the load bearing capacity deficiency, so the collapse performance analysis of the structure is carried out by direct analysis method to obtain the number of overstressed rods, strength deficiency, tensile / compression length / slenderness ratio deficiency and stability deficiency. Research shows that for this kind of structure, reinforcement needs to be carried out without stopping production and with the least impact on the original structure, and internal welding is not allowed. It is more economical to consider the application of non-prestressing cables, while non-prestressing cable members will relax under a certain load combination state, therefore, non-prestressing cables have to consider the problem of relaxation failure under multiple load combination states. By applying non-prestressing cables, the number of overstressed bars can be effectively reduced, which can provide a reference for this type of structure in reinforcement design.
