Abstract
The objective of this study was to comparatively analyse the physical parameters, basic chemical composition and the macro- and microelement content of offal obtained from fattening pigs raised in deep litter and slatted floor housing systems. The experiment involved a group of 80 Puławska fatteners, including 40 pigs kept in deep-litter pens (group I) and 40 pigs in slatted pens without bedding (group II). Offal (tongues, kidneys, hearts, lungs and livers) was evaluated for weight, physical characteristics (pH45, pH24, WHC), chemical composition (water, protein, fat) and the content of minerals: macro- (K, Na, Mg, Ca) and microelements (Zn, Fe, Mn, Cu). Based on the results obtained, associations were found between housing system and basic chemical composition of some offal, i.e. percentage of water (slatted floor<deep litter) and protein (slatted floor>deep litter) in lungs, content of protein (slatted floor>deep litter) and fat (slatted floor<deep litter) in liver, and content of fat in heart (slatted floor<deep litter). The amount of macro- and microelements was significantly differentiated by the housing system with regard to the kidneys: potassium, magnesium, calcium and manganese (slatted floor<deep litter), sodium (slatted floor>deep litter); lungs: sodium (slatted floor>deep litter), potassium (slatted floor<deep litter); and liver: iron (slatted floor>deep litter) and copper (slatted floor<deep litter). In general, the housing system of fattening pigs modified the physical parameters and chemical composition of the analysed offal.

Abstract
The honey bee has a significant environmental and economic impact. While collecting food or water, bees are exposed to negative physical and chemical factors that lead to physiological and behavioral changes and, consequently, even death. Along with the development of technology and communication, electromagnetic fields produced by artificial emitters have begun to have an impact on the environment. The aim of the study was to check whether the electromagnetic field also impacts antioxidant enzymes functioning in the honey bee's organism. The study was conducted under laboratory conditions, and one-day and seven-day-old honey bee workers were used in the experiment. Honey bee workers were exposed to an electromagnetic field with a frequency of 50Hz and variable intensity in the range of 1–10 kV/m. Immediately after the end of the exposure, hemolymph was collected from the bees for biochemical analysis. The results of the research did not show clearly whether changes in the activity of biochemical markers were affected by the time spent in the electromagnetic field or its intensity but did show that there was a difference in physiology between one-day-old and seven-day-old bees.

Abstract
Propolis (bee glue), a valuable biological mixture produced by European honey bees (Apis mellifera L.), is widely used as a remedy in traditional and alternative medicine, as an effective food biopreservative and as a nutritional value enhancer. The present study aimed to investigate eighty propolis samples collected from all twenty-eight districts of Bulgaria in the period of 2020–2022 in order to determine their physicochemical properties as well as their antioxidant and antimicrobial potential. The raw propolis samples exhibited brown or green colour depending on the climatic zone from which they are collected and pH values from 4.82 to 5.87, while the moisture content ranged between 0.98% and 2.97%. The total phenolics content (TPC) and total flavonoids content (TFC) varied from 63.14 mg GAE/g to 737.27 mg GAE/g, and from 29.22 mg QE/g to 234.17 mg QE/g, respectively. The propolis samples demonstrated significant antioxidant potential determined by DPPH and FRAP methods, from 18.56 mM TE/g to 1598.66 mM TE/g and from 82.28 mM TE/g to 1208.81 mM TE/g, respectively, whose values showed a positive correlation (r
2) with the TPC and TFC. The results from the antimicrobial screening revealed that the methanolic propolis extracts in concentration of 20 mg/ml exhibited the highest inhibitory effect on the Gram-positive bacteria such as Micrococcus luteus 2YC-YT, Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25923, Listeria monocytogenes NBIMCC 8632 and Listeria innocua ATCC 33090.

Abstract
Surveys were conducted in Malatya and Elazığ provinces of Eastern Türkiye between 2018–2019 to detect the presence and distribution of Deformed wing virus (DWV), Acute bee paralysis virus (ABPV) and Black queen cell virus (BQCV) infecting honey bees and Varroa mites. Thirty Varroa mites feeding on honey bees and 147 honey bees were collected from twenty-five apiaries of Malatya and fifteen apiaries of Elazığ. The collected samples were subjected to reverse transcriptase-polymerase chain reaction. All tested viruses were found to be present in the samples singly or as mixed infections. The prevalence of the viruses were 23.81%, 12.93%, and 10.20% for DWV, ABPV and BQCV, respectively. Five out of thirty Varroa mites tested for the viruses were found to be infected only with DWV. Randomly chosen sequences of each detected virus’s partial polyprotein gene region were registered in GenBank under the accession numbers OP805878, OP805879, OP805880, OP805887, OP805888, OP805889, OP805890, OP805891 (DWV), OP805881, OP805882, OP805883, OP805884 (ABPV) and OP805885, OP805886 (BQCV). The phylogenetic tree of the viral isolates were compared with the world isolates. DWV isolates were found to be closely related to the UK, Lebanon, Türkiye, France, Germany and Israel isolates, whereas ABPV isolates were related to Türkiye, South Africa, Slovenia, Serbia, France, Hungary, Syria and USA isolates and BQCV isolates were related to China, South Korea, Czech Republic, France, Hungary, Poland, South Africa, Australia and Sweden isolates. The presence of DWV, ABPV and BQCV infections in Malatya and Elazığ provinces of Türkiye is revealed for the first time in this study.

Research subject. The structure of the pre-Paleozoic deposits and different-age Precambrian basement of the East European platform based on geological and geophysical data.Aim. To trace the evolution of the area under study and to study the geodynamics of processes in order to reconstruct the paleostructure of the Baltica continent.Materials and methods. The current state of the consolidated crust was studied using a geological interpretation of seismic profiling data (transects: “EB-1”, “Tatseys”, “Magnit”) and materials of gravity and geomagnetic surveys. The material composition of the basement rock complexes was studied based on drilling data.Results. The Baltica continent forms the basement of the modern East European Platform. After the Sveconorwegian folding about 1000 Ma, Baltica had become part of the Rodinia supercontinent and merged with the North American platform. A passive continental margin with the Riphean-Vendian sedimentary cover was formed on the eastern Baltica edge. The Petrozavodsk-Khopersky orogen, which arose in the place of the Karelian (Early Proterozoic) Petrozavodsk-Khopersky paleoocean, was reconstructed. The submeridional suture was a result of this paleoocean closure. The orogen structure, as well as that of the paleocontinent Baltica, was disturbed and partially destroyed by subsequent tectonic processes, which continue at the present time with modern rifting.Conclusions. The closure of the Petrozavodsko-Khopersky paleoocean led to the formation of the Baltica continent, which included three microcontinents – Sarmatia, Fennoscandia and Volga- Uralia. Baltica became part of the Rodinia supercontinent during the Sveconorwegian orogeny. Volga-Uralia was located on the border with the PaleoPacific and had a Late Riphean sedimentary cover of the Rodinia supercontinent. This margin underwent destruction during a collision with the Timanides. The scale and extent of the reconstructed Petrozavodsk-Khopersky orogen is comparable to Paleozoic orogenic belts, such as Cadomides, Caledonides, Variscides, or Timanides.

Research subject. Lower Pennsylvanian deposits exposed by mine excavations in the watershed part of South Timan.Materials and methods. The research material included data obtained by a field description of sections and an optical microscopy analysis of rock samples (26 specimens). For micropaleontological analysis, oriented thin-sections (97 specimens) were additionally prepared. Trace fossil taxa were determined based on both field photographs and collected specimens. Four oriented rock samples were used to determine the phase composition of the clay fractions from diffraction patterns.Results. The rocks of the Askynbashian (2.7 m), Tashastian (1.4 m), and Akavasian (2.5 m) Regional Stages of the Bashkirian Stage are exposed in the Ikhnitovyi quarry, and the Upper Vereiskian deposits of the Moscovian Stage (1.9 m) are exposed in the Vyemka section. The Ikhnitovyi quarry section exhibits a distinctly cyclic pattern. The cycle bases are distinguished by the appearance of coral and algae limestones, above which thin bedded fine-grained bioclastic and peloidal limestones occur. Greenish illite and chlorite clays indicate shallow sedimentation environments. The carbonate sediments experienced two cementation stages separated by the phase of compaction. The trace fossil assemblage recognized in the Ikhnitovyi quarry characterizes Cruziana ichnofacies. The Vyemka section is of particular interest due to the find of Eofusulina and the presence of typical carbonate tempestites.Conclusions. The Bashkirian deposits were accumulated under quiet shallow-water conditions (coral and algae limestones), on low-gradient tidal flats (fine-grained grainstones), and under a low hydrodynamic activity (probably low-amplitude tides). The illite and chlorite clays identify the accumulation of aeolian material (clay paticles) in ponds.

Research subject.Ostracods and Givetian-Frasnian boundary deposits of the Timan-North Urals Region.Materials and methods.The work was based on the results of studying ostracods from the stratotype sections of the Southern Timan, which are considered referential for regional and global correlations. The analysis of the distribution intervals of the most significant taxa was based on the results of previous studies, both published and archival materials on the Timan-Urals Region. Ostracods were considered in association with conodonts, which is an important criterion for applying a reasonable biostratigraphic subdivision. The use of different-scale regional cyclicity of sedimentation and individual “marking” levels of manifestation of global events were shown.Results.The ostracod distribution in the Givetian-Frasnian boundary interval of the Timan-Northern Urals region was analyzed. The following most significant taxa were identified: Cavellina devoniana, Cavellina uchtensis, Cavellina batalinae, Cavellina chvorostanensis, Nodella faceta, Nodella ex gr. hamata. The correlation of established assemblages with ostracods from the Franco-Belgian basin was shown. The difference consists in the absence of a polyzygid assemblage with Polyzygia beckmanni beckmanni, which was established at the base of the Nismes Formation of Belgium near the historical boundary between the Givetian and Frasnian stages. The determined relationship of biostratigraphic data in combination with the transgressive-regressive sequence of sedimentation shows a more reasonable solution to the problem of the position of the lower boundary of the Frasnian stage of the Upper Devonian in the Timan-Northern Urals Region.Conclusions.An updated version of the scheme of zonal subdivision of the Givetian-Franian boundary interval in the Timan- Northern Urals region has been developed, taking into account the ostracod distribution of the Cavellinidae and Nodellidae families, as well as the discrepancies in the levels of the first appearance of index species and the boundaries of zones in the regional stratigraphic scheme. The correlation of ostracod zones relative to the conodont scale is shown.
Analysis of Madden-Julian Oscillation (MJO) on extreme rainfall event in the west coastal south Sulawesi for mitigation disaster
Authors: Matandung Rekun , Sujiono Eko Hadi , Subaer Subaer 
Published: July 2023

Madden Julian Oscillation (MJO) is one of the global phenomena that affects weather and climate conditions in Indonesia. MJO increases the rainfall rate and causes a plethora of extreme rainfall occurrences in areas along its trajectory. Those extreme rainfall events could trigger hydrometeorological hazards that endanger the surrounding environment. As the first step to analyse this extreme weather event, this research tries to determine the threshold of the extreme rainfall rate. The method used for determining the threshold is the statistical method 98th percentile. The next step is to identify the frequency trend of the extreme rainfall in the period of 1991 to 2020, by measuring the rainfall rate and comparing it with the normal value. If the rainfall rate is above the normal condition inÂ a certain threshold, then it is considered an extreme rainfall event. After that, these extreme rainfall occurrences are compared to the active MJO phase to find out the influence of MJO to the rainfall in the west coast of South Sulawesi. Then, the dynamical atmospheric conditions are to be analysed during those extreme rainfall events. The result shows that the frequency trend of extreme rainfall events are generally negative in 5 (five) regions, which means an insignificant correlation between MJO andÂ rainfall rate. In contrast, 3 (three) other regions show a positive trend. The influence of an active MJO on the extreme rainfall rate is about 34,1%. Meanwhile, the rest for about 65,9% is influenced by other factors. The use of MJO indices for generating early warning hydrometeorological disasters is by utilising the MJO monitoring data, supported with the analysis of dynamical atmospheric condition in the west coast of South Sulawesi.

Сложные оксиды, особенно соединения со слоистой структурой, являются объектом пристального внимания исследователей. Особое внимание связано с наличием у них необычных электрических, магнитных, оптических свойств. К перспективным материалам следует отнести галлаты лантаноидов, в частности галлат гадолиния. Их синтез является многостадийным. Он протекает при высоких температурах. В процессе синтеза применяется мехактивация реагентов, а также неоднократный размол продуктов с последующим отжигом. При этом большая часть работ посвящена получению гранатоподобных структур. Синтез и исследование сложных оксидов со структурой перовскита ограничены. Галлат гадолиния состава GdGaO3 с перовскитной структурой был синтезирован методом соосаждения гидроксидом аммония из азотнокислого раствора нитратов гадолиния и галлия с последующим отжигом продуктов. Образовавшаяся после прибавления в исходный раствор нитратов металлов раствора аммиака смесь осадков гидратированных оксидов гадолиния и галлия Gd2O3∙nH2O и Ga2O3∙nH2О была высушена при температуре 105 ºС в течение 3 часов и прокалена при температуре 850 ºС в течение 30 часов. Температурные параметры синтеза определены по результатам термического анализа. Изменения в составе смесей после проведения синтеза подтверждены методом ИК-спектроскопии. Анализ ИК-спектров показал образование продуктов, не содержащих исходных веществ. Продукты взаимодействия идентифицированы методом рентгенофазового анализа. Установлено образование в системе гексагонального галлата гадолиния GdGaO3, принадлежащего к структурному типу GdFeO3, с параметрами кристаллической решетки a = b = 3,777 Å, c = 10,770 Å.
