Authors:   Northern Trans-Ural State Agricultural University, Yakubyshina Lyudmila I.
Published: April 2024

The studies were carried out in 2014–2017 on the study of three predecessors (peas, corn, pure fallow) and their influence on the growth and development of barley varieties Vorsinsky 2, Chelyabinsky 99, Acha, Abalak. Correlation relationships between the weight of grain per ear and the weight of 1000 grains (r = 0.90), field germination and safety of plants for harvesting (r = 0.94), leaf area and seed yield (r = 0.77 ± 0.18), field germination and yield (r = 0.88 ± 0.14), yield and grain weight per ear (r = 0.89 ± 0.15). As a result of the research, it was found that the traits that form the yield of barley seeds are interconnected and depended on the predecessors. The best precursor for obtaining a high yield of barley in the conditions of the Tyumen region is a clean fallow, which provided the maximum level of seed yield (81.2–82.4 %).

The widespread and frequent recurrence of limb diseases in cattle results from the irrational use of antibiotics and lack of knowledge about the qualitative composition of microorganisms living in wound surfaces. The issue of increasing the effectiveness of therapeutic and preventive measures against the cattle limb diseases must be addressed using an approach that takes into account the characteristics of the qualitative composition of microbiocenoses and their resistance to antibiotic and antimicrobial substances. The studies were conducted in 2018–2022. They focused on the microbial composition and sensitivity to antibiotic and antimicrobial substances in Holstein cattle with an average milk production of 10,500 kg. The disk diffusion method was used to test sensitivity of bacteria to an extended spectrum of antibiotics (amoxiclav, ampicillin + sulbactam, gentamicin, levofloxacin, oxacillin, ofloxacin, tetracycline, chloramphenicol, fosfomycin, cefazolin, cefotaxime, ceftriaxone, ciprofloxacin, erythromycin) in accordance with methodological guidelines MUK 4.2.1890-04. The sensitivity of fungi to antimycotics (amphocetrin, itraconazole, caspofungin, ketoconazole, clotrimazole, miconazole, nystatin, flucytosine, fluconazole, econazole) was studied using the disk diffusion method. The study aimed to test the antibiotic resistance of microbial communities in cattle with Mortellaro disease and Rustergolts ulcer. The study has found that the microbial communities of wound surfaces formed in Mortellaro disease and Rusterholtz ulcer are inoculated with 13 types of microorganisms that are sensitive to antibiotic and antimicrobial drugs. Most of the identified bacteria (except for Klebsiella pneumonia, Streptococcus spp. and Enterococcus spp.) proved insensitive to tetracycline antibiotics. The greatest spectrum of antibiotic resistance was found in Enterobacter cloacea and Enterobacter sakosaki: most strains proved insensitive to amoxiclav, gentamicin, levofloxacin, ofloxacin, tetracycline, cefazolin, cefotaxime, ceftriaxone and ciprofloxacin. Yeast-like fungi Candida albicans were insensitive to amphocetrin, nystatin, flucytosine, caspofungin, and Candida krusei to caspofungin and miconazole.
COMICAL MODERNITY
Authors: Hakkarainen Heidi
Published: April 2024

Though long associated with a small group of coffeehouse elites around the turn of the twentieth century, Viennese “modernist” culture had roots that reached much further back and beyond the rarefied sphere of high culture. In Comical Modernity, Heidi Hakkarainen looks at Vienna in the second half of the nineteenth century, a period of dramatic urban renewal during which the city’s rapidly changing face was a mainstay of humorous magazines, books, and other publications aimed at middle-class audiences. As she shows, humor provided a widely accessible means of negotiating an era of radical change.

Authors: Polyakova N. V. , Shumikhin S. A. , Shakina T. N.
Published: April 2024

Lilac enjoys popularity in landscape design due to its high decorative value during flowering, unpretentiousness, and sustainability. However, depending on the climatic conditions of cultivation, lilacs may exhibit growth and phenological development peculiarities. This work aims to determine the patterns of seasonal development and growth rates of some varieties of common lilac in botanical gardens of three regions: the Republic of Bashkortostan, Perm Territory, and Saratov Region. The work was carried out over three years (2020–2022) based on lilac collections in the botanical gardens of Ufa, Perm, and Saratov. The objects of research are five varieties cultivated in all three botanical gardens (Beauty of Moscow, Salavat Yulaev, Mme Lemoine, Sensation, Katherine Havemeyer), as well as two varieties (Nafisa and Gulnazira) common to the botanical gardens of Ufa and Perm. It has been established that the initial phases of the growing season (bud dehiscence and the beginning of growth of vegetative shoots) in the seven studied varieties of common lilac in Perm, Ufa, and Saratov begin relatively uniformly in each region and generally depend on the average air temperature and the amount of precipitation. The importance of the genetic characteristics of the variety prevails starting from the flowering phase, which is confirmed by the close dates of the beginning of the flowering stages, the end of flowering, and the growth of vegetative shoots, regardless of the place of study. The annual growth of vegetative shoots probably has a more complex relationship, determined not only by specific weather conditions but also by a range of other factors, particularly soil conditions, microclimate, techniques used, and the level of agricultural technology for cultivating samples.

Authors: Toropova E. Yu. , Kamenev I. A.
Published: April 2024

The study aimed to evaluate the biological and economic effectiveness of fungicidal soybean disinfectants of different mechanisms of action in a tank mixture with inoculants in the forest-steppe of the Novosibirsk region. The studies were carried out in 2019–2022. Generally accepted methods are used in the conditions of the northern forest steppe of the Novosibirsk region. For the studies, we used the systemic protectant Baritone (prothioconazole 37.5 g/l + fluoxastrobin 37.5 g/l) at a rate of 1.5 l/t and contact Maxim (fludioxonil 25 g/l) at a rate of 2.0 l/t t, the inoculant was HiCoat Super Soybean (HCSS) 1.42 l/t together with the nutrient medium HiCoat Super Extender (HCSE) 1.42 l/t. On average, over four years, the development of soybean root rots, according to the predecessor winter wheat, exceeded the harmfulness threshold in the control variant by 1.3–2.7 times over the years; the maximum indicator was noted in the dry year of 2022 when soybean plants experienced double stress - hydrothermal and biotic. F. oxysporum, F. poae, F. equseti, F. sporotrichioides, and F. solani were isolated from the underground soybean organs during the growing season. The pathogenic complex of soybean root rots also included fungi of the genera Pythium and Rhizoctonia. The biological effectiveness of seed treatment against root rot was 40.2–76.4% and was higher when soybean seedlings developed in moist conditions. The economic efficiency of seed treatment was 103–347% over the years, with a maximum in wet years. The best option for pre-sowing seed treatment is the contact disinfectant Maxim, 2.0 l/t in a tank mixture with the inoculant HiCoat Super Soya (HCSS), 1.42 l/t together with the nutrient medium HiCoat Super Extender (HCSE), 1.42 l/ T. Both fungicidal disinfectants showed a bactericidal effect on symbiotic nitrogen-fixing bacteria, reducing the number of nodules to 43.2% and their weight to 38.1%. Treatment and vaccination of soybean seeds positively affected the quality of the resulting crop. The protein content was the highest in the Baritone variant together with the inoculants HCSS + HCSE and amounted to 41.4% versus 36.8% in the control. Dressing agents had a significant positive effect on the quality of soybean seeds of the new crop; the best aftereffect was found in the Maxim variant, 2.0 l/t + inoculants, where the prevalence of all phytopathogens was below the ETH (economic threshold of harmfulness), and germination was maximum.

Published: April 2024

The experimental part of the work was carried out based on the seed production department of the Omsk Agrarian Research Center in 2020-2022. Breeding lines of spring soft wheat were represented by three ripeness groups: mid-early – G 6/17, G 8/17, G 10/17; mid-season - G 7/17, G 15/17, G 16/17 and mid-late - G 11/17, G 14/17, G 17/17. The varieties Pamyati Azieva, Duet, and Element 22 were standard. A complex system of indices was used to evaluate the samples for drought resistance, based on comparison of yields under stressful and favorable conditions. The most common indices were calculated: average productivity (MP), endurance index (TOL), yield stability index (YSI), drought resistance index (DI), and stress intolerance index (STI). The total rank score for all indices was calculated. Based on estimating a set of drought resistance indices, five samples with the highest number of points were identified: G 6/17, G 7/17, G10/17, G 11/17, and G 15/17, which can be used in further selection. The calculation of correlation coefficients revealed a high positive relationship between average productivity and the stress tolerance index (0.99), as well as the yield stability index (0.73), between the endurance index and the drought resistance index (0.89). A close positive relationship was also established between the stability and stress tolerance indexes (0.76), indicating a relatively high reliability.

Authors: Mishra Raghvendra , Soni Lavina , Shukla Sunil Dutt
Published: April 2024

The pervasive presence of artificial light in urban environments significantly affects biodiversity. This study investigates the impact of light pollution on avian biodiversity in Udaipur, India. Excessive artificial lighting alters natural habitats, disrupts ecosystems, and affects the behaviour and abundance of various avian species.

The study was conducted in Udaipur from December 2019 to March 2023, utilizing Visible Infrared Imaging Radiometer Suite (VIIRS) DNB Free Cloud Composite Imagery and field surveys. The research spanned rural and urban landscapes, employing methods such as timed species counts and point counts to assess avian fauna. The Shannon-Wiener Diversity Index was used to measure biodiversity, with ANOVA and Tukey’s post-hoc tests for statistical analysis.

VIIRS data analysis revealed three light pollution clusters: dark, moderately dark, and bright areas. Avian diversity varied across these clusters, with significantly higher diversity observed in dark areas. Daytime and night time observations also showed variations, with higher biodiversity observed at night. Common species exhibited significantly higher abundance in brighter areas, while moderately dark and dark areas supported greater diversity.

Artificial lighting has profound effects on avian biodiversity in Udaipur. Bright areas exhibit reduced biodiversity, while dark areas support richer ecosystems. This study underscores the importance of managing light pollution to preserve avian diversity and maintain ecological balance in urban environments.

Published: April 2024

Background: Spirulina platensis contains natural pigments along with phenolic and flavonoid compounds that may be excreted to the supernatant in addition to biomass during culture. Objectives: We prepared enriched cheese and ice cream using biomass and supernatant of S. platensis microalgae extract. We aimed to evaluate these algae’s organoleptic and nutritional properties. Methods: After preparing a 30-day culture of Spirulina, different concentrations of its biomass and supernatant extract were prepared to enrich cheese and ice cream. In the next step, the physicochemical and antioxidant properties of the products were measured by FRAP (ferric reducing antioxidant power) and DPPH (2,2-diphenyl 1-picryl hydroxyl) methods. Expert evaluators performed the sensory analysis according to the Iranian national standard method in terms of color, odor, taste, texture, and general acceptance on a scale of 0 to 5. Finally, statistical analysis of the data obtained from each experiment was performed with a one-way analysis of variance three times using SPSS software, version 24. Results: The results showed that the content of protein, fat, ash, and biomass was higher in enriched foods. However, in enriched ice creams, the content of protein, fat, sugar, and aeration rate increased significantly compared to the supernatant. In addition, cheese and ice cream fortified with supernatant had significantly greater antioxidant activity than biomass. The results of the hedonic test showed that with increasing concentrations of these agents in fortified cheeses and ice creams, the level of satisfaction in odor, taste, color, texture, and general acceptance factors was increased. Conclusion: The study results showed that adding biomass and supernatant of S. platensis to ice cream and cheese increased the nutritional value and improved the taste of these foods. Because these substances play an essential role in children’s diet, this microorganism can be used to combat malnutrition and a diet without micronutrients.

Published: April 2024

Background: Tissue staining is pivotal in histology and histopathology, shouldering a noteworthy role in identifying and classifying tissues and diseases. Due to their non-production of toxic effluents, the utilization of plant-based dyes aligns harmoniously with environmental sustainability and the well-being of laboratory personnel and the general public. Furthermore, this approach is highly cost-effective, further enhancing its appeal. Objectives: This research study explored the feasibility of staining various tissues in mice, such as the liver, kidney, intestine, and cartilage, utilizing a dye extracted from black carrots. Methods: An ethanol extract of 200 g of fresh black carrots (Daucus carota L.) was prepared using 95% ethanol saturated with two different solvents in 200 mL of distilled water. Subsequently, the prepared sections of mice tissue were immersed in the extracted dye solution for 20 minutes, followed by assessment using a light microscope. Hematoxylin-eosin staining was used as a control. Results: The dye extracted from the black carrot using alum and acetic acid successfully stained the cartilage, kidney, intestine, and liver tissues, giving them a bluish-gray coloration. Phytochemical screening further confirmed the presence of anthocyanins in the black carrot extract. Conclusion: The dye derived from black carrots exhibits natural tissue staining capabilities, making it an alternative to hematoxylin-eosin in histology and histopathology laboratories.

Authors:   The Institute of Management and Economy Research, Kim Jong-Hee
Published: April 2024

Purpose - The purpose of this study was to examine the main determinants of the gap between housing demand and house affordability. Design/methodology/approach - This study used the micro-level data of 60,043 households from Korea Housing-Finance Corporation by covering the period 2011 to 2022. Findings - First, the trend of general housing demand showed a higher figure in the future demand than in current demand. And such a tendency showed in all types of households, a relative young, low income, and single households. In the case of current housing demand, it has increased by 2022 from the beginning of 2013, while the future demand has rapidly increased from 2020. Second, although the house affordability showed a higher figure in current housing demand by 2019, its trend changed to be higher in future housing demand from 2020 by a rapid decreasing affordbility in current demand. In the case of young householders, the current house affordability was higher than that of future. The figure of low income householders was below 1 point in both periods, and house affordability of single householders showed a similar level in both periods. which showed over 1 point. Third, financial regulation on housing markets induced th widening of the gap between housing demand and house affordability, and such a trend is much atronger in the future(potential) gap of demand and affordability. More specifically, the strengthen financial regulation leaded to the widening of the gap in all types of households, a relative young, low income, and single households. Research implications or Originality - The effect of financial regulation is necessary to consider under the features of each households.

Purpose - The purpose of this study is to assess the perceived importance and satisfaction of domestic tourists who visited Venice, Italy, regarding the attributes of overtourism. Design/methodology/approach - An online survey was conducted to measure the tourist perceived attributes of overtourism from November 8th to 22nd, 2023. Convenience sampling was employed to target study participants who are domestic tourists in Venice, Italy. A total of 127 responses were used for analysis, including frequency analysis, paired-sample t-tests, and Importance-Performance Analysis (IPA). Findings - First, the results of the IPA showed that attributes related to urban facilities and spaces directly associated with travel behavior were highly rated in both importance and satisfaction by tourists. Second, attributes related to carrying capacity were perceived as highly important but had lower satisfaction level. Third, tourists evaluated the management of affordable prices for tourism products as both less important and less satisfying. Lastly, attributes related to the protection of local businesses showed higher satisfaction levels compared to their perceived importance. Research implications or Originality - This study contributes to an extended understanding of overtourism by examining the phenomenon from the tourists' perspective.

Published: April 2024

Purpose - This study aims to quantify the long tail effect in the digital economy. It also investigates the role of digital platform before and after the COVID-19 pandemic. Design/methodology/approach - We take advantage of a granular data set from one of the biggest digital platforms in Korea. Rather than computing the absolute number of products sold or the Gini coefficient, we estimate the slope of the log-linear relationship of the non-parametric sales distribution. Findings - We find that the use of online food order and delivery services is positively associated with individual restaurant’s sales growth. We also document that the long tail effect is increasing over time. Long tail effects are clustered in the cross-section where average revenue per order is high or the restaurant belongs to the top 50% of the sales distribution. Research implications or Originality - The findings may indicate that digital platforms are contributing to the development of the digital economy in Korea. Also, we confirm that digital platforms make it possible for small and sole proprietors to go through the difficulties induced by the COVID-19 pandemic.

Latar Belakang: Pada 22 Agustus 2022, 4 siswa sebuah SD di Kecamatan Sukorejo dibawa ke Puskesma dengan keluhan muntah dan sakit perut setelah memakan permen lunak “X”. Metode: Penelitian dilakukan dengan metode kohort retrospective. Wawancara dengan siswa menggunakan kuesioner terstruktur dilakukan untuk mencari siswa yang memiliki gejala mual, sakit perut, pusing, diare, muntah dan menyatakan adanya rasa logam di mulut setelah memakan permen lunak pada tanggal 22 Agustus 2022. Pemeriksaan laboratorium kimia oleh BPOM Surabaya dilakukan untuk mengidentifikasi formalin, timbal, kadmium dan arsen pada permen lunak. Data yang didapatkan kemudian dianalisis menggunakan Chi Square. Hasil: Diantara 113 murid yang ada di sekolah, terdapat 25 kasus (attack rate= 73,5%); berjenis kelamin perempuan sebanyak 59.65%; bergejala mual 58.8%, dan mengalami sakit perut 55,9 %. Median masa inkubasi adalah 30 menit. Kurva epidemik berupa common source. Murid yang memakan permen lunak berisiko mengalami keracunan yang signifikan secara statistic (RR=29,41, 95%CI=7.37-117.29). Pada setiap permen lunak seberat 25 mg, terdapat kandungan dalam jumlah sedikit berupa timbal (0,115 mg/kg, standar penyajian: ≤1 mg/kg), kadmium (0,005 mg/kg, standar penyajian: ≤0,5 mg/kg), dan arsen (0,015 mg/kg, standar penyajian: ≤1 mg/kg). Kesimpulan: Kejadian keracunan makanan ini dikaitkan dengan konsumsi permen lunak “X” mengandung bahan kimia. Bahan kimia berbahaya bagi anak-anak. Pemeriksaan laboratorium lebih lanjut diperlukan untuk menemukan bahan kimia lain dari bahan pewarna dan perasa. Direkomendasikan untuk dilakukan sosialisasi pada anak-anak terkait bahaya kandungan bahan kimia dalam permen lunak, maupun makanan lainnya.
