Acinic cell carcinoma (ACC) of the breast is a very rare, primary salivary gland‐type breast malignancy, with ~100 reported cases in the literature. Limited information about the clinical features and outcomes of patients with ACC is available.

Cutting processes, in general, and wood cutting processes in particular, are complex to explain and describe, depending on a number of influencing factors such as material characteristics, cutting tool geometry and cutting parameters. A thorough understanding of the characteristics of woodworking machining, such as cutting tool wear, cutting forces, energy consumption, and cutting tool stress, gives the opportunity to improve product quality, increase production efficiency, or improve the technological process. In this paper, some characteristic parameters of processing in flat, extensive milling of solid wood of different species are analysed in order to determine the significance of the selected parameters, as well as their mutual influences on the required cutting power.

The research aims to improve the durability and functionality of traditional wooden structures through innovative technologies, reducing the ecological footprint and enhancing the economic viability of local materials. The model benches are made from five different types of indigenous conifer wood: Norway spruce, scots pine, larch, thermally modified spruce, and spruce treated with a copper-ethanolamine based biocide. Sensors installed on the benches allow continuous monitoring of wood moisture, a key factor in determining material durability under specific climatic conditions. Collected data will enable the evaluation of optimal wood types for various climatic conditions, promoting the wider use of indigenous, environmentally renewable materials. The project also aims to connect the wood protection industry with end-users, fostering sustainable approaches to environmental preservation, cultural landscapes, and wooden heritage. The research results support the application of wood materials in sectors such as agriculture, maritime transport, and tourism, contributing to ecologically sustainable and economically efficient use of natural resources.

Mathematical modeling is a key tool in engineering as it enables the analysis and prediction of material behavior under specific conditions. This study focuses on material strength, which is one of the most critical aspects of engineering design and manufacturing. Understanding material strength is essential for ensuring the reliability and safety of structures and products. The structure of the paper includes a theoretical overview of the fundamentals of mathematical modeling and regression analysis, a detailed description of the experimental research, the development of a model based on collected data, and the evaluation of the obtained mathematical model. Testing was conducted using a tensile testing machine, with samples of standard dimensions in accordance with EN 10002.

In this paper, we will process the results of experimental and numerical analysis on the example of the boom of a machine tool - a rotary excavator. Rotary excavator SRs 1200/630 KW - 22/2, engine no. 1, field “D”, produced by “LAUHAMER” - German Democratic Republic, is intended for mining coal and tailings at the surface mine of the JP RB “KOLUBARA” Lazarevac mine. During the regular overhaul and after 35 years of operation of the rotary excavator, it was concluded that it would be necessary to assess the stress and deformation state of both the rotary excavator as a whole and its vital parts individually (primarily the excavator booms) through adequate tests. The goal is to determine the critical points on the arrow structure after the tests have been carried out and act preventively to avoid accidents and additional unnecessary costs. By comparing the experimental and numerical results, we obtained a representation of the stresses and strains on the shaft construction and defined the critical stresses and strains.

Background: The European honey market is reported to be in a trou-bling state, far from being considered healthy. A comparison of honey with other food commodities has been conducted to identify specific characteristics of the conducing sector that may provide inspiration for measures to regulate hon y markets. Market indicators: Several general indicators used to describe markets for food production have been analysed to examine the current state of the honey market, offering insight into the primary market challenges or honey-anessential prerequisite developing strategies to address these identified challenges. Variations in market indicators between EU Member States are also presented. Policies related to market indicators: The overarching aim of the European Union, as defined by the Lisbon Treaty, is summarized, alongside a review of some relevant EU and national regulations related to apiculture. Policy me sures previously implemented to regulate certain aspects of other food commodity markets are evaluated for their feasibility in the hon y market. Results and conclusions: It is argued that regulatory me sures could potentially impro e the stability and security of income for beekeep-ers within the honey market. However, there is a risk, or possibly an opportunity, that such measures could drive production towards larger and more professional beekeepers, while smaller, amateur beekeepers may face economic and other difficulties in meeting the stricter regulatory requirements

In this paper, a comparison between serverless databases and conventional data storage models is discussed, with a focus placed on architectural differences, performance measures, cost-benefit analysis, and use case applicability. In cloud-native applications, the use of serverless databases, in which resources are dynamically allocated as needed, is increasingly observed. In contrast, traditional databases require manual operations for infrastructure provisioning and maintenance. Situations in which serverless databases are preferable, as well as those where traditional approaches remain suitable, are characterized in this work. A guide for selecting a database system in modern computing environments is provided, based on an evaluation of systems such as AWS Aurora Serverless, Firebase, PostgreSQL, and MongoDB.

Dynamic analysis can be used to determine dynamic displacements, time history, and the frequency content of loads. One of the analytical techniques for calculating the linear response of structures to dynamic loading is modal analysis. In modal analysis, the structural response is decomposed into several modes of oscillation. A mode is defined by its frequency and shape. Engineers refer to the mode with the lowest frequency (longest period) as the fundamental mode of oscillation. This paper presents Holzer’s approximate method for determining the modes and periods of oscillation for frame structures. The proposed approximation method, based on the relative stiffness of floors and the ground level, is also analyzed. The results obtained using the proposed approximate procedure do not significantly deviate from those obtained through more precise calculations. Therefore, it is emphasized that the method can be used both in practice and for verifying computer analyses of complex systems.

Plywood is a wood-based material that, due to its good properties, has found applications in many areas of the wood industry, transport, and construction. Plywood is fabricated from multiple layers of veneer glued together with the grain direction of each layer of veneer perpendicular to that of the adjacent layers. In order to improve primarily mechanical properties, plywood is reinforced with various fibers, both natural and synthetic. Basalt is used in various forms as a material for reinforcing composite materials. Basalt mesh is primarily used in construction to improve the properties of wall and road structures. In order to determine the possibility of using basalt mesh in the production of wood-based composite materials, plywood reinforced with basalt mesh was produced in laboratory conditions. One, or two, or three basalt meshes were placed in different positions in the panel construction. The manufactured plywood reinforced with basal mesh was tested in accordance with EN 310. The paper presents the results of the bending strength test depending on the quantity and position of the basal mesh in the plywood construction.

The genus Temnostoma comprises saproxylic hoverflies whose larvae develop by boring into wet, decaying wood, where they feed on microorganisms. Records of these species in the northwestern Balkans are sparse in the literature and nearly absent from openaccess databases. To enhance knowledge of their distribution in the region, we present new records of four Temnostoma species from Croatia, Bosnia and Herzegovina, and Serbia. Three species were recorded in all three countries, while T. apiforme was found exclusively in Croatia. This discovery marks not only the first record of this species in the country but also the first for the entire Balkan Peninsula. Furthermore, Temnostomameridionale was documented in Bosnia and Herzegovina for the first time. Given thatthese hoverflies are large and visually striking, we hope this study will inspire interestamong citizen scientists and encourage future contributions to the documentation ofthis genus in the region.

Considering that two-layer parquet is composed of two lamellas—most commonly 10 mm birch plywood and 4 mm solid oak—bonded together with adhesive, and that profiling is required to create a joint that serves a mechanical function, the process becomes complex and imposes significant demands on the cutting tool. This paper presents an experimental analysis of how the type of cutting tool affects the surface quality, profile stability, and edge wear of the tool after a certain machining length. Two different technological solutions were analyzed: a tool with replaceable tungsten carbide (TC) inserts and a tool with an integrated polycrystalline diamond (PCD) cutting edge. A particular focus of the analysis is the wear of the TC tool in the area of the oak and plywood joint profile, where selective wear of the TC edge occurs, potentially causing profile deformation and a weaker joint. The obtained results show that using PCD tools in two-layer parquet profiling achieves better surface finish, longer tool life, more consistent geometry of the cutting edge, and thus a more stable parquet profile.
