MICROSTRUCTURE, MINERALOGY AND PHYSICAL PROPERTIES OF KAOLIN & METAKAOLIN GEOPOLYMERS USED FOR SOLIDIFICATION AND STABILIZATION OF OIL AND GAS DRILLING WASTE OPERATIONS

(STEF92 Technology, 2022-12-27, Laila Houd Ben Giuma, Muna Hassan Bek)

Show more

The production of oil and gas includes drilling a number of wells for exploration or production activities. During drilling operations, large volumes of drilling fluids are used to facilitate the process. In Libya, after completion of drilling operations drill cuttings and waste drilling fluids are typically discharged close to the oil fields without treatment. This can result in negative ecological impacts on the surrounding environment e.g. through infiltration of toxic constituents into soils and underground wa...

To address these issues, one key solution is the utilization of renewable materials such as biomass. Biochar, made from biomass materials is seen as a potential option to replace the fossil fuel-based reductants. Pyrolysis is the most common way of producing biochar. However, the physicochemical properties of biochar are significantly influenced by virgin biomass characteristics and the pyrolysis condition such as...

(STEF92 Technology, 2022-12-27, Gulnaz Galieva, Kamalya Karamova, Polina Galitskaya, Svetlana Selivanovskaya)

Show more

Chicken manure is one of the most wide spread waste worldwide. One of its hazardous properties is contamination with live pathogens or pathogens- spores. Being introduced into soil for fertilization, fresh, cured or treated manure can cause soil contamination with those pathogens. Further, transmission of the pathogens through soil and plant tissues to human or animal food is possible. The objective of the present work was to reveal the level of pathogenic contamination of wheat grains cultivated on soil that was ...

Show more

The study of ultra-low frequency (ULF) waves and geomagnetic pulsations plays an important role in better understanding the mechanisms of their generation and spread in the magnetosphere and on the ground. The magnetospheric ULF waves, which provide useful information about the conditions in the solar wind and in the magnetosphere, can be detected on the ground by different types of magnetometers and recorded as geomagnetic pulsations - continuous and irregular. This paper aims to study the characteristics of Pc5 ...

PECULIARITIES IN THE INITIAL STAGES OF DEVELOPMENT FOR SOME FRUIT TREES, DEPENDING ON THE TEMPERATURE CONDITIONS

(STEF92 Technology, 2022-11-15, Petya Malasheva, Valentin Kazandjiev, В. Георгиева)

Show more

The last decade has been characterized by an increased frequency of climatic anomalies and their amplitude. These anomalies affect the productivity of crops and orchards, which is directly dependent on agro-meteorological conditions. The registered tendencies to change the hydrothermal conditions in the different regions of the country sometimes are a risk factor for their productivity, especially in the initial phenological stages of the development of the fruit trees. Bud dormancy on the fruit trees from the tem...
