Abstract:
A substance administered to plants with the intention of enhancing nutrient availability is referred to as fertilizer. The goal of this study project was to find a solution to the issue of environmental contamination brought on by the buildup of dry leaf detritus. Compost is created using dry leaf waste as the primary component and EM4 as an aid.EM4 is responsible for breaking down the organic material in leaves. The characteristics of the pre-made dry leaf compost are its blackish brown hue, crumbly and somewhat rough texture, lack of odor, and loose granular shape. The method of research use

Abstract:
Studies of beekeeping products reveal the presence of a significant complex of biologically active substances in them, which arouses great interest among scientists and specialists in the field of medicine and nutrition. One of the little-studied products – perga, is characterized by a unique composition of complex compounds, characterized by their natural harmony, bioavailability and synergistic interaction. This research substance, which is the result of the active activity of bees, includes a balanced spectrum of biologically active components that can affect various aspects of human health

Abstract:
The study of tire recycling is one of the core environmental aspects, as tires waste is a complicated substance and cannot be rid-of easily. For that reason, this paper concentrates on tires recycling principle and takes the tires substances of a specific size that is called (crumb rubber). The paper studies the advantages of using tires waste into concrete mixture and aims to address how tires waste can strengthen the characteristics of concrete such as improving its thermal conductivity and sound insulation priorities. The results of the study reached to a point that tires waste can work as

Abstract:
Whole grain breads and gluten-free bread products are commonly associated with crumbly texture, poor color, low volume, poor flavor, and short shelf life, possibly due to a weak or absent cohesive network that forms gluten. Thus, some defects in dietary bread in the functional direction are associated with ineffective gas retention and expansion during kneading, which leads to a decrease in the volume and softness of the crumb. The current challenge of the work is to overcome these limitations.The recipe for a new range of whole grain bread and gluten-free bakery products has been created. The

Abstract:
Rye-bread belongs to traditional food in Europe and is preferred by elderly people in Germany. But those people often have difficulties with chewing the firm crust of those breads which, therefore, gets cut off. Current opinion suggests that flavor substances, produced during baking, diffuse from crust to crumb and therefore, bread baked with weak or without crust does not taste well. In present study, however, it was determined by triangle tests as well as color and firmness measurements, that crumb of crustless bread is nearly similar to crumb of bread with crust.

Abstract:
Soil organic matter (SOM) is probably the most important constituent of soils. The effect of SOM on soil properties far exceeds the relative percentage of this material in soils. The small amount of organic matter in soils, usually from 1 to 5%, is very important in providing a reserve food source for microorganisms and higher plants. Almost all properties of SOM are beneficial for plant growth. Soil organic matter can be defined as a complex, heterogeneous mixture of plant and animal remains in various stages of decay, microbial cells—both living and dead—microbially synthesized compounds, an

Abstract:
Inherent properties of a soil determine the extent to which that soil will erode. These properties are soil texture, soil structure, soil permeability, and the amount of soil organic matter. Soil texture consists of a mixture of soil particle sizes of sand, silt, and clay. Soil texture is also related to water movement into the soil [infiltration] and water movement through a soil (permeability). Sand grains are large and difficult to move; however, they are easily detached. Clay particles often stick together and therefore are difficult to detach; however, once detached the clays remain suspe

Abstract:
Earthquake can make structures damaged and crumble. The traditional approach to seismic design has been based upon providing a combination of strength and ductility to resist the imposed loads. Thus, the level of the structure security cannot be achieved, because the disadvantage of the designing method is lack of adjusting capability subjected to an uncertain earthquake. The presence of some damping (energy dissipation) in buildings has been recognized and studied by professional researchers.
