The measurement of texture is a widely used method in postharvest and food research. The majority of the textural characteristics of fresh foods, such as vegetables and fruit, are frequently employed as maturity indicators in order to meet long-term storage, transportation and customer fulfillment requirements. Understanding the textural features is also crucial for controlling processing processes like drying, heating, and frying on processed foods. The sensory qualities of the texture have been evaluated using a variety of methods. The methods for measuring texture that are most frequently used are objective tests using a variety of tools. The set of physical qualities referred to as a food’s textural properties includes those that arise from the structural elements of the food, are primarily perceived through touch, are associated with the distortion, disappearance, and the response of food under the action of a force and are evaluated objectively by functions of quantity, distance or time. Due to their well-balanced supply of nutrients, including sugars, organic acids, vitamins, pro-vitamins, and minerals, as well as non-nutritional, advantageous components like fiber and secondary metabolites, fresh fruit and vegetables are vital dietary items for human nutrition. Production processes need to be managed sustainably while producing high-quality products. At harvest, the maturity stage is typically an important factor not only affecting the product quality at harvest but also the susceptibility of the product postharvest. In postharvest, the main task is maintaining the good quality of perishable products for as long as possible to avoid food waste and economic losses. Consequently, knowledge of factors related to produce quality in the pre-harvest, harvest, and post-harvest stages is relevant for the producer, harvest manager, storage manager, packaging facility personnel, local markets, global distributors, wholesalers, and consumers. The word quality is consistently used throughout the production-to-consumption chain, but its definition changes depending on where in the chain you are. Yet, in each of these stages, quality refers to the product’s level of excellence and lack of defects (absence of defects and blemishes, cultivar-typical ripeness, freshness, a non-harmful amount of residues considering pesticides and other chemicals, and cleanliness). Texture represents one of the four principal factors defining food or fruit quality, together with appearance, flavor, and nutritional properties, and plays a key role in consumer acceptability and recognition of agro-foods.

Techniques and Methods for Measuring the Texture of Processed and Fresh Agro-Food Products – A Review

<abstract xmlns="http://www.w3.org/1999/xhtml">

In this paper, the expression of the electrostatic interaction force between two charged particles is derived in the framework of Stochastic Electrodynamics. The fundamental assumption is that the electrically charged particle can be modeled as a two-dimensional oscillator that scatters the classical zero point field background radiation. The correct expression of the electrostatic force is obtained if the natural pulsation of the oscillator is equal to the Zitterbewegung angular velocity.

The use of drones in agriculture and building thermoscanning have become two innovative methods in recent years. A drone is a remotely piloted device equipped with video cameras and other advanced technologies that can fly at different heights and collect data and information useful for agriculture and buildings. In agriculture, drones can be used to collect data on crop health, identify areas affected by diseases and pests, monitor irrigation and soil fertility and plan harvests. Building thermal scanning can be used to identify heat loss, identify weaknesses in building structures and detect thermal insulation problems. The use of drones in agriculture and building thermoscanning can reduce costs and labor time while improving production and efficiency. These are examples of how technology can be used to support sustainable development and environmental protection.

The Use of Drones in Multispectral Photogrammetry and Thermoscanning –A Review

<abstract xmlns="http://www.w3.org/1999/xhtml">

The dynamics of drug release from polymeric structures are presented in the context of the Scale Relativity Theory, by using a fractal Fokker-Planck type equation, isometry by inversion of fractal coordinates (spatial and temporal coordinates of fractal type) is shown, which can describe different nonlinear processes implied in drug release dynamics.

“Holographic” Type Implementations in the Description of Drug Release Dynamics

<abstract xmlns="http://www.w3.org/1999/xhtml">

A new mathematical method in the drug release dynamics is proposed using Scale Relativity Theory. Our method is completely different than the standard one, because the variables through which we can describe the release dynamics are non-differentiable mathematical functions (i.e. mathematicals functions both dependent of spatial and time coordinates, and also of scale resolutions). In such context, the scale resolution is correlated with drug release degree so that various drug release regimes can be highlighted (gradual drug release, saturation, decay of polymer matrix etc.).

BULLETIN OF THE POLYTECHNIC INSTITUTE FROM IAȘI, Section Mathematics, Theoretical Mechanics, Physics – BIPMF (ISSN-L 1224-7863) is an international journal, with quarterly appearance, for the free publication of research results in theoretical and mathematical physics, mechanics, technical and applied physics, material sciences.  The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes physics, mechanics and mathematics, and given their importance in material sciences, interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, surfaces/interfaces are welcomed if they demonstrate insight into physics, seeking to understand mathematical basis of physical phenomena, and solve problems in physics via mathematical approaches. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.  BIMMF aims to enhance the interdisciplinary research by connecting the fundamental sciences as physics and mathematics with applicative research concerning the relationships between structure, processing, properties, and performance of materials. It also promotes international exchange of scientific activities.  The journal publishes original research, focused review articles that examine the state of the art, book reviews, technical notes, case studies, and preliminary communications, with no restriction on the length of the papers.  Archiving  Sciendo archives the contents of this journal in Portico - digital long-term preservation service of scholarly books, journals and collections.
