    Opis:
    This review presents the usage of adhesives and binders for agglomeration of particle materials, including waste, in order to obtain strong bodies. The binding materials were classified into three categories: inorganic binders, organic binders, and compound binders. Many examples of the agglomeration effect of binders in view of their adhesive and thickening reveal that they have a significant impact on the qualities and use of waste lumps. Binders for fine waste granulation, briquetting, and pelletizing were demonstrated in-depth. In all cases, the mechanical strength of the agglomerates produced was increased. It was observed that the majority of the additives may be easily obtained from waste resources, posing a minimal environmental risk.

    Opis:
    Minirhizotron, a non-destructive technique is based on the application of transparent tubes, located in plant’s root zone. This method has been known since the beginning of 20th century and is used for plant root’s observations, especially in forest trees (Scots pine, Norway spruce, silver fir, birch), steppe grasses, vegetables and cereals. Minirhizotron technique is also applicable to pomological plants observations, mostly apples, but many others orchard species were observed with this method last years. The study of root growth dynamics in fruit plants using the non-destructive, minirhizotron method is conducted in the Pomological Orchard in Skierniewice. The objects of the observations are the roots of: apple trees cultivar. ‘Gold Milenium’, blackcurrant bushes cultivar ‘Tiben’ and sweet cherry cultivar ‘Vanda’. The observations were carried out monthly over a period of from March to November.

    Opis:
    This is a scoping review of agglomeration techniques to obtain of solid bodies from particle waste-materials for their utilization. For this purpose, the granulation and briquetting of fine coal and fly ash were presented in detail. Many successful works on solid fuels production, with coal only, and also with the addition of biomass, were presented. During the solid fuel combustion in power boilers, significant amounts of ash are generated. The properties of fly ashes were taken into consideration, and different methods of their utilization were proposed to obtain a wide range of useful products. Con-sequently, the waste resources of coal and ash were fully utilized. In final remarks, it was concluded, that the agglomeration techniques play an important role in waste management, but particularly in the circular economy.

    Opis:
    Soil modification with Portland cement is the most common practice in geotechnical engineering. The application of micro-fine cement causes proper intrusion of the provided slurry into the soil voids and consequently decreases the porosity to a greater quantity. In order to determine the utility and behavior of cements with different blains, non-destructive and destructive tests such as grain-size distribution of cements by laser-ray, sedimentation, permeability and compressive strength were employed. The results of experimental studies and observations demonstrated a suitable mix-design for upper and lower parts of the cement-grading curve that are of prime importance for grouting and stabilization. Meanwhile, by increasing the fineness of the cement, the permeability decreases to a considerable extent and the compressive strength increases. Moreover, the blain content close to 5000 cm2/gr application led to the optimization of the effect of void reduction in a grouted soil mass compared to the lower and higher amount of blain content. The results of various tests indicate that an optimum blain can be used to achieve the designed geotechnical criteria.

    Opis:
    The article presents the process of welding of steel movable platform supports. There is a growing demand for the welding of difficult-to-weld fine grain steels used in civil engineering and transport. An example of this could be the use of high-strength movable platform supports. The recently used material in the production of movable platform supports are fine-grained steels due to their high tensile strength of 1000 MPa. The joints formed using them, however, are characterized by much lower strength than the native material. In this article, the most appropriate parameters were selected for welding the movable platform supports made of difficult-to-weld fine-grained steel S960 MC.
    Wzrasta zapotrzebowanie na spajanie trudno-spawalnych stali drobnoziarnistych stosowanych w inżynierii lądowej i w transporcie. Przykładem tego może być stosowanie wysokowytrzymałych podpór podestu ruchomego. Ostatnio stosowanym materiałem w produkcji podpor podestów ruchomych są stale drobnoziarniste z uwagi na ich dużą wytrzymałość na rozciąganie na poziomie 1000 MPa. Powstałe przy ich wykorzystaniu złącza cechują się jednak dużo niższą wytrzymałością od materiału rodzimego. W niniejszym artykule dobierano najwłaściwsze parametry do spawania podpór podestu ruchomego z trudno-spawalnej stali drobnoziarnistej S960 MC.

    Opis:
    In today’s scenario, recognition of pictured food dishes automatically has significant importance. During the COVID-19 pandemic, there was a decline in people visiting restaurants for their dietary requirements. So many restaurants started offering their services online. This situation caused a demand for better categorization of food into various categories on a large scale by companies that facilitated these services. It is challenging to congregate a large dataset of food categories, so it is complex to build a generalized architecture. To solve this issue, In this paper, domain-specific transfer learning is used to build the model using some standard architectures like VGGNET, RESNET, and EFFICIENTNET family, which are trained on popular benchmark datasets such as IMAGENET, COCO, etc. The similarity between the source and target datasets is calculated to find the best source dataset, and the one with the highest similarity is chosen for transfer learning. The solution proposed in this paper outperforms some of the existing works on categorizing food items.

    Two pitched six-blade turbines of different diameters were used in measurements of just suspension impeller speed in fine and standard suspensions. Dependences of the modified Froude number on particle size and their concentration were determined from the measurements in standard suspensions and the impeller speed for fine clay suspensions were calculated. The obta-ined values were compared with experimental results taken from measurements in fine suspensions.
    Dwa mieszadła turbinowe z pochylonymi łopatkami zastosowano w pomiarach szybkości mieszania niezbędnej dla wytworzenia zawiesin drobnoziarnistych i standardowych. Zależności zmodyfikowanej liczby Fronda od wielkości cząstek i ich stężenia określono na podstawie badań przeprowadzonych w zawiesinach standardowych. Z zależności tej wyznaczono prędkość obrotów niezbędną dla wytworzenia zawiesiny drobnoziarnistej. Wartości obliczone porównano z wynikami doświadczalnymi otrzymanymi dla zawiesin drobnoziarnistych.

    Opis:
    Risk scoring methods applied in risk assessments used in Turkey, differ from each other in terms of analysis methods, scoring the risks, presumption and sensitivity levels. This article aims to eliminate the effects of divergent results of different risk analyses of lifting equipments used in the building industry and develop a practical hybrid risk analysis and ranking method. In this study risks of lifting equipments used in the building industry were scored by conventional Fine-Kenney risk analysis method first. Secondly, with the experience of previous accidents on construction sites, the reasons of accidents were sorted into 7 main criteria, which being ‘Demographic’, ‘Behavioral’, ‘Machine Related’, ‘Working Environment Related’, ‘Economical’, ‘Administrative’ and ‘Organizational’ criteria and related sub-criteria. Developing these criteria was supported by the experience of inspections carried out by labour inspectors. The weighted scores of these criteria were calculated by AHP method using a questionnaire applied to 14 experienced labor inspectors. The weighted scores obtained by the analytical hierarchy process method (AHP) were multiplied by the scores obtained by Fine-Kinney risk assessment method and a new integrated risk assessment and ranking application was introduced. With this application, a different priority rank was created and which risk to be eliminated primarily was determined. Keywords: analytical hierarchy process, lifting equipments, fine-kinney, occupational health and safety, integrated risk analysis, ranking method
