Abstract:

The paper studies durability of metal bridge spans as resource reliability and operability characterized by their performance specifications and maintainability before the limiting state. The ultimate condition of superstructures, in which further operation is impractical without restoration work to ensure operation conditions. The qualitative assessment of the resource durability of superstructures is based on the supposition that they maintain the normative operability at least for the specified operational period from incubation and service life to residual resource, indicating the possibil

Abstract:

We study concurrent processes modelled as workflow Petri nets extended with resource constrains. Resources are durable units that can be neither created nor destroyed: they are claimed during the handling procedure and then released again. Typical kinds of resources are manpower, machinery, computer memory. We define structural criteria based on traps and siphons for the correctness of workflow nets with resource constraints. We also extend the soundness notion for workflow nets to the workflow nets with resource constraints; extra conditions concern the durability of resources. We prove some

Abstract:

Due to the large and unsustainable use of valuable natural resources and electronic waste generation worldwide, which poses risks to human health and the environment, different organizations have initiated efforts to shift from a linear economy to a circular economy. A crucial aspect of promoting a circular economy is improving product durability, which can reduce resource extraction and waste because products remain in use for a longer period. Methods for measuring and indexing durability should encourage consumers to buy more durable products and incentivize manufacturers to compete in impro

One strategy to address these concerns is to use waste additives as fluxing agents in bricks.

Introduction. The article explores the stress-strain state of a distribution pair of aggregates of a volumetric hydraulic drive and the search for ways to increase its durability. Materials and Methods. In the process of studying, the generally accepted principles of the theories of friction, reliability, elasticity, mechanisms and machines, and mathematical modeling were used. To simulate the stress-strain state, an engineering analysis system ANSYS was used. Distribution pairs of hydraulic pumps 313.3.112, GST-112 and Sauer Danfoss 90R075 were chosen as objects of study. Results. As a result

Abstract:

The development of machine designs occurs with a constant desire to increase their productivity, which is almost always accompanied by an increase in the mechanical and thermal tension of the movable joints of parts. At the same time, the tasks of achieving high reliability and durability of the machine, reducing its weight, reducing the consumption of scarce materials are set. Based on a comprehensive assessment of automotive parts that determine the resource, it was found that abrasive wear prevails over all other types of wear. About 83% of automotive parts have wear up to 0.6 mm. When inte

Abstract:

In most clinical cases the operational durability of the hip endoprosthesis is limited by physiological changes in the bone tissue accompanied by stability loss of the implant fixa-tion in the bone hole. The problem of the durability of the endoprosthesis structure itself is considered solved, but the existing standards for testing the strength and wear resistance of the implant guarantee its reliability only in a limited period of time. The capabilities of modern diagnostic equipment make it possible to determine individual physiological loads on the hip joint and ensure control over the indi

Abstract:

The motor shaft of a gas turbine engine, being a highly loaded part of a particularly critical purpose, has increased requirements for maintaining the level of properties during long-term operation, ensuring the structural strength of the product. An increase in the resource and durability of the product is achieved due to the development of new materials that surpass the used domestic and foreign analogues in their mechanical characteristics. FSUE «VIAM» has deve-loped high-strength structural steels with enhanced characteristics of strength, toughness, durability and heat resistance.

Abstract:

Despite 30 years of research on global value chains, the appropriation of nature in general and natural resource industries in particular remain marginal both theoretically and empirically. There is a parallel ecological deficit in labour process theory and a lack of applied research on natural resource industries. But since historical capitalism is based on the expanding appropriation and transformation of nature by labour, these lacunae must be redressed.

Abstract:

Agricultural residues serve as a vast yet underutilized biomass resource with significant potential for bioenergy and biomaterial applications. Converting these residues into densified biomass pellets enhances energy density, handling efficiency, and transportability, offering a sustainable alternative to conventional feedstocks. While extensive research has focused on woody biomass, studies on the pelletization of vegetable crop foliage remain limited. This study examines the pelletability of foliage from corn, soybean, tomato, eggplant, cucumber, and summer squash, assessing their physical p

Abstract:

Here, we test whether the increase in tooth height in insular endemics results from the expansion of the dietary niche under resource limitation, as widely considered, or whether it represents an investment in dental durability in response to the selection for extended longevity under low levels of extrinsic mortality. We tested these hypotheses in the extremely hypsodont fossil bovid Myotragus balearicus from the Balearic Islands, an ideal model to study the evolutionary trends on islands. Dental abrasion was significantly lower in the insular bovid than in highly hypsodont continental artiod
