The assessment of genetic diversity is a key step in evaluating the adaptation of populations to new environmental conditions, and thus in the selection of new cultivars. The present investigation aimed to assess genetic variability of bread wheat (Triticum aestivum L.) genotypes grown in Algeria. The 17 hexaploid genotypes of bread wheat were assessed using 16 molecular microsatellites of SSR (Simple Sequence Repeat). Among the 16 microsatellite markers tested, only 11 markers were the most polymorphic and reprod...

21 strains of E. coli isolated from wild partridge birds - P. Perdix from the western part of Romania were studied.

Hemolytic activity was highlighted in a single strain of E. coli 1/21 (0.21%). The final identification of E. coli strains isolated from wild birds was done using the...

One of the main challenges in treating landfill leachate through membranes is managing the resulting concentrate. Depending on the membrane installation's performance and the stored waste's characteristics, significant quantities of concentrate may remain after leachate treatment. Therefore, it is necessary to identify an optimal disposal or treatment method for it. In the European Union List of Waste, the membrane concentrates are associated with leachates and are classified as either hazardous or non-hazardous w...

The use of a total station for carrying out high-precision work on the alignment of the stands of a continuous casting machine is an urgent task that directly affects the quality of steel.

The soybean (Glycine max) is the most important bean in the world, providing a wide range of vegetable proteins. Soybean is an important source of many bioactive compounds, w...

Airborne particulate matter (APM), and in particular its fine fraction PM2.5, is well known as an important pollutant in the urban atmosphere worldwide. The health effects of APMs depend not only on their size but also on their chemical composition. Black carbon (BC), heavy metals and other constituents can impact human health and climate. The main sources of BC are the incomplete combustion of fossil fuels, biomass burning and other organic materials. Resuspension of soil and road materials, secondary aerosol for...

The article deals with the use of traffic calming elements to improve the environment, slow down traffic and increase safety for cyclists and pedestrians in urban centers in the Czech Republic. Calming elements also have a significant influence on the architecture of the street space. Traffic calming factors can be divided into psychological factors (e.g. road signs) and physical factors (e.g. road narrowing) or a combination of them based on their effect on drivers. These can be used at intersections and road sec...

Testing the club convergence hypothesis, studies addressed the heterogeneity of EU member states either from energy or environ...

Vegan alternatives to cheeses are in growing demand in European markets as more and more people are either lactose intolerant or switching to a plant-based diet. When the consumer chooses to buy a vegan cheese, his expectations are that the vegan product has the nutritional and organoleptic characteristics as similar as possible to those of conventional cheeses. This work aimed to obtain two variants of vegan alternative to cheese, using coconut milk as the raw material: one with the addition of white pepper and g...

The consequences of human actions on Earth are becoming increasingly evident, leading us to consider that the -climate collapse has begun-, as the General Secretary of the United Nations (UN) warned at the beginning of September 2023. At less than a decade from 2030, the goals and its targets for sustainable development (SD) in the UN 2030 Agenda are far from being achieved, requiring urgent actions. Their fulfilment is at risk, particularly considering recent events such as the war(s) and the pandemic. Developing...

The use of hydrogen as a fuel requires as much research as possible on the construction and functional parameters for the development of appropriate burners. The researches undertaken are addressed to diffuse flame burners with concentric jets of fuel and air. These burners cannot lead to flame return, the combustion being much safer, than for the case of burners with fuel-air mixture. The researches were carried out by numerical modeling through the ANSYS-FLUENT V.14.0 software. An important stage of the research...

In additio...

Aphids have grown significantly both in number of species and in number of individuals in populations, especially in green spaces in urban environments. By feeding, they affect the plants in the structure of the ecosystem at the foliar and floral level, therefore it is necessary to manage them so that they are numerically reduced but at the same time to avoid the application of pesticides. Through this work, 2 ways of management were tried for 5 months (April-August): by exploiting existing natural enemies and by ...

Determining the optimal trajectory of a manipulator is a mathematically complex part of control due to the time-consuming determination of inverse kinematics, the complexity of which increases as the manipulator's degrees of freedom increase. The control of manipulator actuators is based on algorithms focusing on the shortest possible control time and zero position deviation. Values such as power consumption, which affect the growth of the carbon footprint, are not taken into account. For this reason, alternative ...

In 2011, it was decided that the carrying public transport system in Bratislava would be tram transport. Today's transport system is based on radials, it was created as part of Bratislava's first comprehensive transport concept in the ?70s. One of the disadvantages of Bratislava's public transport system is the few tram lines in the city centre, which, with a large number of radials, causes vehicles from different radials to cluster together at dense and poorly spaced intervals. The disadvantage of the radial syst...

The transition to sustainable pathways of economic development depends on the clear understanding of the sustainability principles, but it also needs ability to evaluate critically conventional professional practices and rethink them into sustainable one. However, the previous years of struggling for economic transformations have showed a serious issue - lack of action competence when it comes to the implementation of the sustainable solutions. The design thinking is a core of professional competency and high perf...
