This paper presents an innovative approach to optimize traffic networks in a supplier-customer system based on specific strategies of game theory. The traffic network is represented as a routing configuration in which the arcs represent various possible roads between supplier and customer entities, each route having an associated transport cost for the product unit. The game structure is defined by a matrix of transport costs between the players, supplier and customer, with their corresponding strategies. Based on these costs, the game matrix is built to which the existing quantities in warehouses are added, respectively the quantities requested by the final customers. By solving the game associated to the transportation traffic network, the different strategies are proposed for choosing the optimal solution. The simulation results confirm the effectiveness of the proposed approach and recommend some performant procedures for solving the game, such as Hurwicz, Laplace and Savage, close to optimal solution. This research opens new directions for management optimization in other domains such as comunication, electrical and administrativ networks. [ABSTRACT FROM AUTHOR]

In this paper, we explore how to use a Nvidia Jetson Nano and Python to create a system that detects weariness in a person's face using computer vision and machine learning techniques. The system captures the person's face in real time, preprocesses the picture to cut noise, then detects the face using Haar cascades. Next, using computer vision algorithms, characteristics associated with weariness, such as the eyes, are retrieved. These characteristics are then used to build a machine learning model that can predict weariness in the live stream feed. Lastly, using a graphical user interface, the findings are shown, and the system may be fine-tuned to increase accuracy. This device might be used in applications such as driver monitoring and traffic safety. [ABSTRACT FROM AUTHOR]

This paper presents an analytical solution of the differential equations describing the pulsatory liposome dynamics. We consider a unilamellar liposome filled with an aqueous solution of osmotic solute inserted in a hypotonic aqueous medium. Due to the osmosis process the liposome has a cyclic evolution. The lipid vesicle swells to a critical size, at which point a transbilayer pore suddenly appears. Part of the internal solution leaks through this pore. The liposome relaxes and returns to the initial size. The swelling starts again and the liposome goes through a periodical process. The swelling of the liposome is described by a differential equation. The appearance of the pore changes the evolution of the liposome. The internal solution comes out through the pore and the liposome starts its deflation (relaxation). The evolution of the pore has two phases: first, the radius of the pore increases to its maximum value, then the radius decreases until it disappears, and the liposome reaches its initial size. During each cycle, the liposome will release a quantity (a pulse) of the solution from its interior. All the processes which contribute to the liposome relaxing and its coming back to the initial size are described by three differential equations. This system of differential equations can be integrated using numerical methods. The functions - which model our biological engine in three stages, are as follows: R(t) - the liposome radius, r(t) - the pore radius, C(t) - solute concentration, Q(t) - the osmotic solute amount inside the liposome. The graphs representing these functions contain important linear portions, which suggested a solution using analytical methods. Based on some analytical methods, we solve these equations, and their explicit solutions are validated by comparing with numerical results of previous studies. [ABSTRACT FROM AUTHOR]

The ability of soybean (Glycine max) and vetch plants (Vicia) to stimulate the degradation of low-density polyethylene (LDPE) in soil was tested in the vegetative experiments under laboratory conditions. It was shown that the presence of LDPE strips in soil had no toxic effects on either of the plants, and that, in the case of soybeans (Glycine max), it stimulated plant growth. It has been shown that soybeans (Glycine max) and vetch (Vicia) can stimulate the degradation of LDPE depending on the particularities of the soil and the presence of plant growth stimulating factors. The vetch plants (Vicia) were relatively more effective in stimulating the LDPE degradation in case of unpolluted soil, collected from the forest. Soybean plants (Glycine max) were relatively more efficient under polluted soil conditions and lead to the highest rate of LDPE degradation (2.3% in 39 days) -- in the variant with seed bacterization by Rhizobium japonicum RB-06. The ability to ensure a significant degradation of LDPE, under the real toxic conditions of polluted soil, highlighted the perspectivity of soybean plants (Glycine max) for the development of phyto-remediation procedures of lands polluted by non-recyclable plastic and other contaminants [ABSTRACT FROM AUTHOR]

Avian Influenza is an infectious, contagious disease of an acute evolutionary type with an epizootic enzootic character, affecting numerous species of domestic and wild birds, clinically characterized by serious general disorders, accompanied by respiratory, digestive, nervous phenomena and an edema of the subcutaneous connective tissue from head and neck region, and morphopathologically through hemorrhagic lesions in various tissues and organs. At present it is spread in most European countries, America, Asia and Africa. It is of great economic importance due to its very high morbidity and mortality. Because the disease is underdiagnosed, and people do not notice the illness or mortality occurring in their livestock, the virus is very difficult to control. The number of cases of infection increases in the spring and autumn due to the migrations that migratory birds perform. They either start the migration already infected, or become infected during the migration, in the stopovers where the disease develops. Infected birds do not manage to reach the end of the migration, the body being weakened due to the fight against the virus, they can no longer fly and end up dying in the territories of the free countries, leading to new outbreaks of Avian Influenza.

Forage pea (Pisum arvense f. aestivale), also known as field pea, is one of the important species cultivated in our country for the feed of several animal species, due to the remarkable content of the grains in proteins, calcium, vitamins, but also in other essential elements for animal nutrition. Also, together with oats, it forms the spring mash, which is well-known for its high fodder quality. The research carried out during three experimental years, in the climate and soil conditions of the Arad Plain, regarding the cultivation of spring forage pea, highlighted the importance of soil fertility, as well as the importance of the water from precipitation during winter and growth period. Among the three experimental years (2020, 2021 and 2022), the best results regarding grain production were recorded by the spring forage pea variety Salamanca with determined growth, in the year of 2021, on a cambic chernozem, low carbonate, medium loam/medium loam clay type of soil, when the grain production exceeded 4.800 kg/ha, STAS grains. The same genetic material (Salamanca variety), cultivated under identical technological conditions, on a weakly stagnoglazed vertosoil, medium loam clay/dusty-clay type of soil, achieved a significantly lower grain production, of less than 4.000 kg/ha. It is remarkable that, in the all three years of spring forage pea cultivation, the grain production obtained on the cambic chernozem type of soil exceeded, each time, the value of 4.000 kg/ha, while, in the case of the vertosoil, every year recorded a production below the value of 4.000 kg/ha, making soil fertility as one of the most determinant factors for production of this significant legume crop.

The main ideea of the paper is to reduce the hardware and software effort required for a simulation process using an identified model. Since the results are consistent, based on the observations of the data related relationship to the minimum necessary is proposed for a simulation that leads to a neglectable error. This relationship is used in the case study made on a multiple model control type architecture that aims to switch smooth control algorithms. The proposed system is implemented and tested in real-time software for a nonlinear plant laboratory.

Being considered as the "queen of fodder plants" due to its great fodder and economic value, alfalfa (Medicago sativa) is one of the traditional legumes species cultivated in our country. The fodder value of this species is reflected by a series of distinguished nutritional characteristics, such as a balanced energy-caloric intake, high protein and vitamin content and high degree of consumption and digestibility. Also, alfalfa is widely used in the nutrition of most animals, in different forms, such as: soilage (green mass), hay, silage, granules or mixed fodder. At the same time, this species also presents great importance from an economic point of view, due to many advantages, such as: high productions obtained, great ecological plasticity, special agro-biological properties, the ability to enrich the soil in nitrogen and being a main component of the green conveyer for the feed of milk cows and young taurine. The importance of alfalfa for the agricultural sector of our country is major. This can also be quantified through the continuous development activity of new autochthonous varieties, such as Mihaela and Dobrogea (4AG07), which show increased resistance to drought and to common diseases, as well as an improved productive potential. By cultivating these two Romanian varieties (Mihaela and Dobrogea) in the pedo-climatic conditions of the Tormac Plain, considered as a favourable area for this culture, this research paper aims to identify the production capacity, respectively the harvest of green mass and hay, obtained by two mowns, without the application of irrigation. Following the research undertaken in the two experimental years, 2020 and 2021, on a vertic preluvosol type of soil with a medium loamy-clay texture and good physical, hydrophysical and chemical properties, the productions of soilage and hay were high, making this crop profitable for the farmers from the studied area.

Part of the annual cultivated grasses from the botanical family of Gramineae (Poaceae), barley (Hordeum Vulgare) is considered as a important cereal crop worldwide, especially regarding its use in animal feed, as beeing known for its many benefits, such as a well-balanced energy and calories intanke and its high protein content. The large scale use of cereals in human and animal nutrition presents a series of special advantages, such as the possibility of long-term preservation of the quality of the grains, the easy forms of transportation, the multitude of uses, or the potential of cultivating these species in various geo-pedo-climatic conditions. Thus, all these advantages have determined the very high share of cereals globally, not only in terms of the agricultural sector, but also in terms of the world trade.

Thus, all these advantages have determined the very high share of cereals globally, not only in terms of the agricultural sector, but also in terms of the world trade. Due to their particular characteristics, such as very good tolerance to the main foliar diseases and high tillering capacity, the new fodder barley varieties have determined the wide spread of this crop, as one of the main cultivated cereal species, known for its reliable and constant productions and which, together with the two-row barley, exceeds 50 million cultivated hectares worldwide.

Many animal-to-human transmissible diseases have been known since ancient times, but the Pasteurian period, which was by far a turning point in the development of microbiology, is the hottest stage of accumulation, substantiation and detection of the causality and pathogenesis of many of these. Peat is an anthropozoosis spread all over the globe, and without being influenced by climate or season, it can have a sporadic, enzootic or epizootic character. The epidemiological aspect correlates with the biology of the species, the main vector. The existence of stray dogs in all regions of a country gives a very scattered character of cases of urban disturbance, with seasonal incidence, favored during the route. Rabies is an acute, sporadic-enzootic encephalomyelitis, found in all homeothermic animal species, transmissible to humans, and characterized by acute evolution with sensory and motor nervous manifestations, expressed by hyperexcitability and aggression, followed by paralysis and death. In all cases of rabies, an immediate diagnosis and urgent action is required, 32 both for animals that are disturbed or suspected of having the disease, and for those that are contaminated or suspected of being infected. As neither the clinical aspects of the macroscopic lesions are pathognomonic, the diagnosis of the disease is based on laboratory exam (virological, biological, histopathological and serological). As it is a major zoonosis, laboratory diagnostic techniques for rabies have been internationally standardized. [ABSTRACT FROM AUTHOR]
