Background: The immunogenicity of different COVID-19 vaccine regimens and combinations in naïve and convalescent individuals has not been formally tested in controlled studies, and real-life observational studies are scarce. Methods: We assessed the SARS-CoV-2 infection and COVID-19 vaccination-induced immunity of 697 hospital workers at the University Medical Center Hamburg-Eppendorf between 17 and 31 January 2022. Results: The overall prevalence of anti-NC-SARS-CoV-2 antibodies indicating prior infection was 9.8% (n = 68) and thus lower than the seroprevalence in the general population. All vaccinated individuals had detectable anti-S1-RBD-SARS-CoV-2 antibodies (median AU/mL [IQR]: 13,891 [8505–23,543]), indicating strong protection against severe COVID-19. Individuals who received three COVID-19 vaccine doses (median AU/mL [IQR]: 13,856 [8635–22,705]) and those who resolved a prior SARS-CoV-2 infection and had received two COVID-19 vaccine doses (median AU/mL [IQR] 13,409 [6934–25,000]) exhibited the strongest humoral immune responses. Conclusions: The current study indicates that three exposures to the viral spike protein by either SARS-CoV-2 infection or COVID-19 vaccination are necessary to elicit particularly strong humoral immune responses, which supports current vaccination recommendations.

The term angiomatosis is used to denote a group of well-known to poorly characterized proliferative vascular entities. In animals, cutaneous progressive angiomatosis (CPA) is a disorder with variable prognosis related to the extension and depth of infiltration of the surrounding tissues by vessels. CPA may share some microscopical features with other vascular proliferations such as low-grade well-differentiated capillaritic hemangiosarcoma (HS), making the diagnosis not always straightforward, especially in small biopsies. The aim of this study is to retrospectively assess the most common diagnostic microscopical features of CPA in dogs. In this work, 11 histopathological criteria were analyzed on 31 CPA and 11 primary cutaneous HS in dogs. Features significantly associated with CPA included: lobular growth, interposition of connective tissue and adnexa between the vascular proliferation, presence of nerve fibers, and a mixed vascular proliferative component. Absence of plump/prominent endothelial cells, lack of atypia, and lack of mitoses were also significant factors differentiating CPA from HS. Additional distinctive findings in CPA, although with no statistical association to CPA diagnosis, were vascular shunting, absence of necrosis, and endothelial cell piling up. In conclusion, the combined use of different microscopical clues allowed for the distinction of CPA from HS and was considered useful for the diagnosis of CPA.

Published: July 2022

Meningitis, caused by bacterial infections such as Streptococcus spp., is a frequently observed cause of death in pigs. In order to implement effective treatment and avoid further losses, it is important to establish this diagnosis quickly. However, this is often difficult because macroscopic lesions may not be visible, and additional laboratory testing may take several days. The present study investigated whether microscopical examination of impression smears of the leptomeninges taken during necropsy can help in establishing a presumptive diagnosis of meningitis in pigs more quickly. In total, 54 pigs suffering from neurological signs and/or (acute) mortality were examined. They were 3 to 10 weeks old and originated from 16 farms. From each pig, bacterial culture was performed on one half of the brain using a swab from the leptomeninges. From the other half, paired cytological impression smears of the leptomeninges were stained with a commercial quick stain dye (Hemacolor®) and Gram stain and microscopically evaluated for the abundance of neutrophils and the presence of short-chain coccoid bacteria. Bacterial culture of the leptomeninges was positive in 36/54 cases, in 28 of which Streptococcus spp. were found. The numbers of smears with low, moderate, or high abundance of neutrophils were 19, 17, and 18, respectively. Short-chain coccoid bacteria were detected successfully in 12 pigs in the Gram-stained smear. The positive predictive value of smears with moderate or high abundance of neutrophils for bacterial presence and, therefore, likely meningitis was 89%, whereas the negative predictive value of smears with low abundance of neutrophils was 74%. The positive predictive value of smears with short chains of coccoid bacteria for diagnosis of Streptococcus spp. was 100%, whereas the negative predictive value was 62%. In conclusion, microscopical examination of impression smears of the leptomeninges of piglets with neurological signs and/or (acute) mortality is a feasible procedure that can help swine practitioners in establishing a tentative diagnosis of meningitis more quickly, especially if neutrophils are abundant, and short chains of coccoid bacteria are present.

Published: July 2022

Among the well-known approaches for controlling seawater intrusion during extensive freshwater abstraction from coastal aquifers is the construction of subsurface dams. In the current research, the SEAWAT code is being implemented to examine the impact of groundwater extraction on the effectiveness of a damaged subsurface dam for controlling saltwater intrusion. Simulations were performed numerically to check impact of the subsurface dam height, dam location, well height, well location, abstraction rate, fracture aperture, fracture location, seawater density and fracture dimension on the effectiveness of subsurface dam as a countermeasure to prevent saltwater intrusion in coastal aquifers. Increasing the abstraction rate from 1 × 10−6 to 5 × 10−6 m3/s caused the seawater to advance more into the freshwater, and the loss of effectiveness increased. The minimum and maximum value of loss of subsurface dam effectiveness was recorded to be 34.6% to 93%, respectively, for the abstraction rates from the well equal 1 × 10−6 and 5 × 10−6 m3/s, consequentially. When the dimensionless value of well height location Lw/Ld is increased from 1.0 to 2.0, the effectiveness of the subsurface dam is reduced by around 20%. The findings demonstrate that the well location, well depth, abstraction rate, location of the dam, fracture aperture, and density of saltwater all affect the effectiveness impairment of the fractured subsurface dam for controlling saltwater intrusion. Decision makers could use findings of this research to better manage groundwater resources in coastal aquifers.

Published: July 2022

Sediment is the main carrier of pollutants in river channels. This study analyzed the distribution characteristics of precipitation, runoff, and sediment and their response characteristics in the Daning River basin. Based on daily precipitation (1979–2017), runoff (1989–2017), and sediment (1997–2017) time series, the Gini concentration index, precipitation concentration index (PCI), precipitation concentration degree (PCD), and precipitation concentration period were applied to assess the concentration characteristics of precipitation, runoff, and sediment on the daily, monthly, and seasonal scales. At each intensity level, precipitation was negatively correlated to the PCI and PCD. The normalized difference vegetation index (NDVI) values had strong negative correlations with rainy days with light precipitation (0.1–9.9 mm). The degrees of concentration were in the same order for the multiscale analysis: runoff < precipitation < sediment. Although the amount of daily precipitation of more than 25 mm displayed a significant increasing trend, suggesting an increased risk of flood and soil erosion, the significantly improved vegetation cover reduced the sediment-carrying capacity of the surface runoff, with significant decreases in the total amount and multiscale concentration degrees of sediment being observed. The results of the study provide a reference for the improvement of the potable water safety and ecological environment in the Three Gorges Reservoir region.

Published: July 2022

Water temperature (WT) is a critical control for various physical and biochemical processes in riverine systems. Although the prediction of river water temperature has been the subject of extensive research, very few studies have examined the relative importance of elements affecting WT and how to accurately estimate WT under the effects of cascaded dams. In this study, a series of potential influencing variables, such as air temperature, dew temperature, river discharge, day of year, wind speed and precipitation, were used to forecast daily river water temperature downstream of cascaded dams. First, the permutation importance of the influencing variables was ranked in six different machine learning models, including decision tree (DT), random forest (RF), gradient boosting (GB), adaptive boosting (AB), support vector regression (SVR) and multilayer perceptron neural network (MLPNN) models. The results showed that day of year (DOY) plays the most important role in each model for the prediction of WT, followed by flow and temperature, which are two commonly important factors in unregulated rivers. Then, combinations of the three most important inputs were used to develop the most parsimonious model based on the six machine learning models, where their performance was compared according to statistical metrics. The results demonstrated that GB3 and RF3 gave the most accurate forecasts for the training dataset and the test dataset, respectively. Overall, the results showed that the machine learning model could be effectively applied to predict river water temperature under the regulation of cascaded dams.

The adaptability of fish to their habitats is closely related to river hydraulics. While navigation channel projects aim to improve the navigation conditions by adjusting the hydrodynamic force of local river sections, the impacts of these projects on the hydraulic indicators of habitats of the four major Chinese carp species (FMCCs) remain unclear. Taking the Daijiazhou reach in the middle reaches of the Yangtze River as a case study, a mathematical model for spawning suitability was established to simulate changes in these hydraulic indicators before and after the implementation of a navigation channel project. The optimal flow rate interval for the spawning of the FMCCs was 17,500–22,000 m3·s−1. After the navigation channel project was implemented, the habitat suitability index (HSI) and weighted useable area (WUA) increased across the spawning habitats of all FMCCs, indicating that the project implementation created more habitat space. The central bar (Chihugang central bar) became exposed during the dry season, with the HSI and WUA decreasing under low water flow but increasing under medium-low or higher water flow levels. At the Daijiazhou bar head floodplain, which remained unexposed during the dry season, the HSI and WUA increased after project implementation, providing more space for spawning and habitation for the FMCCs. For the low point bar with bank gullies (Lejiawan point bar), the implementation of the bar protection zone project restricted gully development, with the HSI and WUA decreasing for all FMCCs. Based on the above impacts of navigation channel projects on the hydrodynamic environment of fish habitats, this paper provides a reference for the optimization of navigation channel arrangement as well as for the restoration of fish habitats.

Published: July 2022

Cladocerans are biological indicators of environmental changes. Their remains provide information on past changes in lake environments. We studied the correspondence between contemporary Cladocera assemblages and their subfossil remains from an oxbow lake. We sought to demonstrate that there were differences among the various sites of an oxbow lake with different utilization based on contemporary and subfossil Cladocera assemblages and physical–chemical variables. The oxbow lake’s two sides are used as fishing sites, where angling is the main activity. The middle site of the lake is under nature protection with high macrovegetation coverage. Contemporary and subfossil Cladocera assemblages were sampled from 21 sampling sites along the oxbow lake. Our research showed that the subfossil Cladocera assemblages had higher species richness and densities (36 taxa) than the contemporary species (29 taxa). We found one species of the Polyphemidae family only in the contemporary assemblage. Among the sites, Cladocera assemblages differed in their species composition and density. The highest densities were found in the second fishing site due to the appearance of the small-sized Bosmids. The relationship between Cladocerans and the physical–chemical variables showed that some variables, such as chlorophyll-a, biological oxygen demand, dissolved oxygen, copper, phosphide, and organic matter content, significantly affected Cladocera composition. We found that the subfossil Cladocera assemblage was significantly more diverse and abundant than the contemporary one, indicating that an integrated sampling may be sufficient to provide better results on the total species composition of the water body.

Private Correspondence as a Source on the History of a Noble Family: The Case of the Białłozor, Koncza and Römer Families (1820s–1880s)

Abstract. The article presents an analysis of the rich collection of private correspondence of the Białłozor, Koncza and Römer families. The addressees and addressers were from a group of inter-married landed nobility, thus the personal destinies of the representatives of these families were associated with the most important political, social and cultural processes underway in the first half of the 19th century. As a result, their correspondence is considered a broad history source. The accounts made of the same events, circumstances and experiences created a uniform narrative characteristic of a group of people sharing a similar sense and view of the world and value system. The correspondence discussed here is suitable for researching the sociocultural model of this group, formed through self-perception, the perception of others and the world.
Keywords: 19th century, landed nobility, private letter, family history, cultural model.

Authors: Arkhipova M. Yu. , Cherviakova A. A.
Published: July 2022

The aim of the economic and statistical study presented by the authors is the evaluation of the role of small manufacturing enterprises in innovation development of real sector of Russian economy. Compared to developed countries, Russia is characterized by a relatively low innovative activity of small industrial enterprises, as well as by their smaller contribution to employment and to the increase of living standards of the population. At the same time, small industrial enterprises have the highest potential for innovation growth, especially in high-tech economic activities. The similarity of small enterprises’ definition in Russia and in the European Union, the magnitude of innovative activity of small enterprises in Europe, and the development of instruments to support innovative companies make studying the European experience in stimulating the innovative activity of small enterprises in the real sector of the economy in order to adapt it to domestic practice relevant.

The authors reveal the potential areas of innovative activity growth for small manufacturing enterprises on the basis of foreign experience as well as develop recommendations on support for small entrepreneurship in industrial sector. The research is based on Community Innovation Survey (CIS), national reports of European countries on the topic, the federal statistical surveys № 4 and № 2-MP provided by the Federal State Statistics Service.

The study revealed key drivers of European small enterprises’ innovative activity: well-developed cooperation with other organizations, substantial investment in R&D, broad coverage of small business enterprises with support measures. Best European practices of small enterprises’ innovative activity and the analysis of the main barriers of Russian small enterprises’ innovative activity allowed to define the promising directions for supporting small business the real sector of economy of Russia: developing modernization programmes for enterprises, extending the access to borrowed financial sources, developing cooperation ties between small business enterprises. The authors highlighted growth points of innovative activity of small manufacturing enterprises that can be taken into account while developing support measures in order to increase small business’ innovative activity, create new jobs and provide population employment.

Authors: Surinov A. Ye.
Published: July 2022

This study draws on the findings of a survey conducted by the Interstate Statistical Committee of the Commonwealth of Independent States (CIS-Stat) in the framework of a joint project with the UNFPA – CISPop «Better Data for Better Policies».

The paper aims to present the author’s assessment of the level of harmonization between the national census programs across the CIS and the inter-comparability of their results in terms of total population size and its composition. The study is based on the analysis of methodological documents, which include census forms, manuals for census enumerators (census takers) and technical materials for census personal, that describes the concepts, definitions, and classifications used in national censuses. For countries where no censuses were taken, the authors used materials from pilot censuses and drafts of census documents.

The study established that among countries there is a high degree of coherence of national census programs in terms of the key topics, concepts, and classifications used, as well as the wordings of the questions and their prompts. Simultaneously, the analysis allowed us to determine that national statistical services of the region focus on the expectations of their respective populations and take into account national legislation, local conditions, and traditions. First of all, nation-specific features manifested themselves in the formulation of questions concerning the economic, educational, and ethno-cultural characteristics of the population.

Analysis of the materials of the works performed on the implementation of the 2020 round of population census programs across the CIS indicates that, based on the data of population censuses conducted in the past few years, it is possible to obtain harmonized data on the size and main characteristics of the population of countries, to provide international comparisons both within the CIS region, and between countries of the region and other countries of the world. International statistical community should be well informed about national practices of the CIS countries so that region-specific features can be accounted for in the international recommendations for future censuses.

Soil is both a support and a nutrient source for the development of living organisms. Composts based on faecal sludge and vegetable wastes were tested on okra to see the proportion of organic matter and nutrients in the soil after two seasons. Thus the control, non-composted faecal sludge and chemical fertiliser were compared with the other treatments T0, T1 and T2. Physicochemical parameters such as pH, electrical conductivity, organic matter, nutrients Carbon, Nitrogen, Potassium, Phosphorus and grain size were analysed. The results showed an increase in organic matter content from the beginning (As = 0.52%) with 1.72%, 1.9% and 1.4% for the soil samples that were amended with T0, T1 and T2 respectively. Thus the pH values are neutral for treatments T0, T1 and T2. The electrical conductivities are between 33-47µs/cm. Mineral elements such as A (0.08-0.1%), P (21.7-29.6%), K (0.02-0.03%), are satisfactory for T0, T1 and T2. The C/N ratio is between 9.5-10.4 and below 12.

Nine common bean genotypes were evaluated at two different environments in Raya valley of southern Tigray, Ethiopia for three consecutive years during 2016-2018 main cropping seasons. The aim of the study was to determine the effect of G × E interaction and to identify the best adaptable varieties for selection environments and yield stability. The study was conducted using a randomized complete block design with 3 replications. Combined analysis of variance for grain yield and most of yield component traits showed highly significant (p ≤ 0.01) differences among the genotypes, environments and for GEI effects. This indicated that the tested environments have an influence on the selected varieties differentially responded to the changes in the test environments. As a result, environment two was identified as more favourable to common bean production, despite some varieties were showed good performance in some traits at both locations. But, no single variety is found that generally superior in all evaluated traits across all locations and years. However, the varieties “Nasir, SAR-119, Awash-2 and SAR-125” were the better performed with yield from combined analysis of 20004.47 kg/ha, 1979.83 kg/ha, 1843.1kg/ha and 1791.49 kg/ha, respectively, followed by genotypes of Awash-1 [1548.93 kg/ha] and Awash Melka [1525.11 kg/ha]. Generally, the application of combined analysis facilitated the visual comparison and identification of superior genotypes, thereby supporting decisions on common bean variety selection and recommendation in tested environments.

This study explored the profitability of raw Bambara groundnut marketing in Enugu Metropolis, Enugu State, Nigeria. Multi-stage survey design was used to sample 60 respondents by means of well structured questionnaire. Descriptive and inferential statistics were used to realise the objectives. Majority of the respondents (78.3%) were males; the modal age was 43-53; mean years spent in school was 16.07 years. Only (28.3%) had access to credit, while (71.7%) financed their businesses through personal savings. Quantity of bambara groundnut sold was significantly and positively influenced by: household size (p < 0.05); access to credit (p < 0.01); and access to market information (p < 0.01). The following results were also observed: GPM 16.5%, NPM 14.7%, BCR 1.17:1, and ROI 17.3%. Major constraints include: inadequate finance with mean score of (3.93), seasonal price fluctuations (3.93), poor road network (3.70), weevil attacks (3.23) and high cost of goods (3.28). The study recommends that the relevant government agencies should formulate policies that will enable the marketers to have access to cheap credit facilities for expansions and even for new entrants, in order to reduce unemployment and poverty levels in the area. Good road networks and commodity storage systems should be provided by the agencies to ensure easy movement of goods, as well as curtail post-harvest losses. Also, the marketers should form/join cooperative societies, and other market associations for easy access to finance and other resources.
