Article: Values for the Mechanical Properties of Wheat, Maize and Wood Pellets for Use in Silo Load Calculations Involving Numerical Methods

Abstract	The mechanical properties of the materials stored in agricultural silos determine the loads they generate under static and dynamic conditions. The present work describes the mechanical properties of wheat, maize and wood pellets. Direct shear and triaxial assay devices, and oedometers (all commonly used in geotechnical assays), were used to determine these materials’ internal angle of friction, Poisson’s ratio, Young’s modulus, apparent specific weight, etc. The results for wheat and maize were similar to those previously reported by other authors. For the wood pellets, the results for the internal angle of friction and apparent specific weight were also similar to those found in the literature. However, this is a relatively new type of material, and few results of this type have been reported, certainly not enough for reference values to be available. This work is the first to report this material’s dilatancy angle and Poisson’s ratio. A table is provided with suggested reference values for the studied mechanical properties of each of the test materials; these can be used in silo load calculations involving numerical methods.

Abstract	In a standard Diamond-Mortensen-Pissarides labour market with frictions, the authors seek to determine when there is more employment with individual wage bargaining than with collective wage bargaining, using a wage equation generated by the standard total surplus sharing rule. Using a Cobb-Douglas production function, they find that if the bargaining power of the individual is high compared to the bargaining power of the union, there is more unemployment with individual wage setting and vice versa. When the individual worker and the union have the same bargaining power, if the cost of opening a vacancy is sufficiently high, there is more unemployment with individual wage setting. Finally, for a constant marginal product of labour production function AL, when the individual worker and the union have the same bargaining power, individual bargaining produces more unemployment.

Abstract	This study focuses on the friction characteristics of chestnut sawn timber (Castanea sativa Mill.) of Spanish origin. The values of both the static and dynamic friction coefficients were determined, as this knowledge is of interest for the numerical simulation of the stress transmission in joints of timber structures. Therefore, two sets of tests were carried out combining different orthotropic orientations. Firstly, timber-to-timber tests were assessed to obtain the coefficients applicable to carpentry joints; secondly, timber-to-steel friction was also evaluated to determine the coefficients needed for mechanical joints with metal plates and dowels. The results presented a conventional behavior of friction, i.e., a maximum static value before sliding and a subsequent decrease. For timber-to-timber tests, global mean values of μₛ = 0.47 and μₖ = 0.36 were found, and the results were slightly higher than those obtained between pieces with the same orthotropic orientation and sliding direction. Regarding timber-to-steel tests, the resulting friction coefficients, as well as the difference existing between the static and dynamic values were lower (μₛ = 0.19 and μₖ = 0.17) compared to the timber-to-timber sets. The use of these results in numerical studies would allow for closer simulations in which chestnut wood is involved in friction. In addition, the values provided herein could be included as new data in standards that already consider other wood species.

Abstract	Introduction: This study assessed if the healthcare system overload and the organizational changes made in response to COVID-19 may be having an impact on clinical and epidemiological characteristics of the peritonsillar infection (PTI). Materials and methods: In a retrospective longitudinal and descriptive follow-up, we reviewed the circumstances of the patients attended during 5 years, from 2017 to 2021, in two hospitals, one regional and other tertiary. Variables related to underlying pathology, history of tonsillitis, time of evolution, previous visits to Primary Care, diagnostic findings, abscess/phlegmon ratio, and length of hospital stay were recorded. Results: From 2017 to 2019, the incidence of the disease ranged between 14 and 16 cases/100,000 inhabitants-year, and decreased to 9.3 in 2020, a 43% less. Patients with PTI consulting in pandemic time were visited much less often in Primary Care services. They showed a greater severity of symptoms and the period of time between their appearance and diagnosis was longer. Additionally, there were more abscesses and the need for hospital admission greater than 24h was 66%. There was hardly a causal relationship with acute tonsillitis, although 66% of the patients evidenced history of recurrent tonsillitis, and 71% concomitant pathology. All these findings showed statistically significant differences with the pre-pandemic cases. Conclusions: The protection of airborne transmission, the social distancing and the lockdown adopted in our country are measures that seem having been able to modify the evolution of PTI, with a much lower incidence, a longer recovery period and a minimal relationship with acute tonsillitis.

Abstract	Greenhouses are employed worldwide to protect crops from meteorological conditions as well as to control some plant production variables. As multi-tunnel structures are amongst the most used, in this article, we focus on cost optimization of both the steel structure and the concrete foundation of this greenhouse typology. Firstly, three structural alternatives composed of three tunnels and differentiated portal frames were dimensioned conforming to the European design of steel structures, namely, Eurocode 3; meanwhile, the foundation was calculated through a previously validated matrix method. Then, genetic algorithms were employed to optimize for cost each proposed design and to evaluate the relative weight of each element in the overall steel consumption. Moreover, the influence of the greenhouse design on the final cost was also assessed, and it was found that the most cost-effective solution corresponded to the optimized greenhouse alternative exhibiting a 3.5 m separation between portal frames and the combination of a steel profile and plastic gutter (i.e., M3OPT at 15.14 €/m²). Finally, from the study on the influence of the portal frame separation, a further cost per square meter reduction was found for a design with the so-called structural gutter (i.e., steel profile and plastic water collection system) as support for the arches and a 4.5 m separation at 14.21 €/m².
