Published: October 2020

Abstract
The study described socio-economic characteristics of the beneficiaries of the Community Based Agricultural and Rural Development Project (CBARDP), profiled the agricultural technologies disseminated and adopted. The study was carried out in Kwara State, Nigeria among smallholder farmers. A multi-stage sampling procedure was employed to select respondents who participated in CBARDP in Local Government Areas (LGAs). At the first stage, one participating LGA was purposively selected from each of the agricultural zones, making a total of nine LGAs. At the second stage, three rural communities were randomly selected from each of the selected LGAs while the final stage involved a simple random selection of ten participating farmers from the selected rural communities making a total of 270 respondents. Data collected were described with the frequency counts, percentages, means and standard deviations whereas Chi-square and correlation analyses were used for inferential purposes. The results showed that the mean age of farmers was 52.1 ± 6 years, majority (92.2 % and 74.1 %) were married and male, respectively. The overall results indicated a moderate level of adoption of CBARDP technologies but high adoption in orchard, fishery, poultry and cattle packages while the respondents had low adoption in livestock, processing, crop production and agro-processing packages. The results showed that significant associations existed between sex (χ2 = 23.934), marital status (χ2 = 34.66), membership of social organisation (χ2 = 23.43), compatibility (χ2 = 362.88, relative advantage (χ2 = 211.69) and adoption of CBARDP technologies whereas there were significant relationship between household size (r = 0.201), farm size (r = 0.537), years of experience (r = −0.375) and farmers’ adoption of CBARDP technologies. The study concluded that adoption of CBARDP technologies was moderate among beneficiaries in the study area. It is therefore recommended that more awareness should be created by relevant stakeholders to encourage especially more women to actively participate in similar projects in the future.

Abstract
In this study we assessed the determinants of lack of credit access among the Indigenous Vegetables (IVs) farmers based on primary data collected in a cross-sectional survey. Using descriptive statistics and logistic regression analysis, the results revealed that more females were involved in the indigenous vegetable production with average age of 40 years, seven household members, eight years of formal education and cultivating 0.76 acre of land. Only 8 % had access to credit and 76 % did not have contact with extension agents. The mean monthly income from indigenous vegetables production, off-farm income and savings were about ₦35,000 (US$96.83), ₦15,000 (US$42.12) and ₦13,000 (US$38.57), respectively. Further, lack of credit access significantly depended on gender (β = 0.15, P < 0.05), educational level (β = 0.11; P < 0.05), farming experience (β = 0.73; P < 0.05), off-farm income (β = 0.23, P < 0.05), saving habits (β = 0. 25; P < 0.01) and annual numbers of extension contact (β = 0.94, P < 0.01) of indigenous vegetable farmers. Therefore, improved access to formal education, extension supports, creation of gender-specific credit scheme and farm-based organisation (FBO) for indigenous vegetables farmers to sustain credit accessibility were advocated.
Soviet Serial Apartment Buildings in Riga Historical Centre Streetscape. 1945–1990
Authors: Garkāje Līva 
Published: October 2020

Abstract
Today’s European historical city centre streetscapes, many of which are designated cultural heritage sites, consist of a mix of urban and architectural housing heritage of different periods, including post World War II period buildings. Nevertheless, knowledge of history of historical centre post-war housing and their artistic and cultural-historical values of this recent past is still insufficient, to a certain degree contradictory, and in some cases even incorrect. This is particularly accurate regarding Modern Movement serial or type Soviet housing in former Soviet republics. This paper presents an ongoing research intended to identify valuable housing streetscape architecture and urban layout traits of post-war period in Latvia (1945–1990) in the environment of historic centre. The goal is to provide specialists in planning and heritage fields with appropriate evaluation criteria and correct know-how material on the theme, as well as general public with cultural historical information considering post-war housing heritage. In this study an example of post-war Modern Movement serial Soviet housing in the historical centre of Riga, the capital city of Latvia, and its protection zone is drawn. The research is based on mapping and auditing streetscapes using Maryland Inventory with this housing typology in historical built environment to identify most common characteristics and qualities of these buildings. The main conclusions are that historical street-scapes do not have significant qualitative differences from historical mixed with post-war housing streetscapes, whereas the quality of streetscapes with dominating post-war modern housing tends to differ from historical streetscapes, as well as has similar shortcomings to those of the large-scale housing block streetscapes.
Characteristics of Laminates for Car Seats

Published: October 2020

Abstract
In the presented research, 11 different laminates were compared, 8 of them were two-layered 3 of them were three-layered laminates. The laminates that were analyzed vary by the type of face-side textile material (knitted and nonwoven textiles), density and thickness of the foam, and specific properties (higher air permeability and low-emission foam). Depending on the different types of laminates, different laminating processes are used: hot-melt, flame, and powder laminations. The purpose of the presented research is to analyze the basic characteristics of the different laminate structures. Properties that are important for these types of laminates are the number of layers, areal density, thickness, resistance to rubbing, fire resistance, water vapor permeability, air permeability, breaking force and extension, thermal conductivity, and stratification. We found that the properties of laminates were not affected by the density and thickness of the foam. Nonwovens and other laminate components do not perform because they have lower abrasion resistance and lower tensile strength than knitted fabrics as the face layer. Knit laminates have good abrasion resistance, high air permeability, and water vapor permeability. Both are self-extinguishing to the first or second mark. Three-layered laminates have lower thermal conductivity and air permeability than two-layered laminates.

Abstract
Ulcers and slow wound healing are common in diabetic polyneuropathy (DP), as well as shooting or burning pain, sensitivity to touch or lack of sensitivity, low oxygenation of nerve tissue, conductivity disorders and various vascular disorders. The mechanisms of DP development are complex and have not been completely studied. To take into account the role of B group vitamins, we investigated histological structure of nerve tissue, the level of different growth factors and the qualitative composition of active proteolytic enzymes in rats with DP and after the use of the metabolic drug Cocarnit for 9 days. This drug composition include nicotinamide, cocarboxylase, cyanocobalamin, adenosine triphosphate disodium trihydrate. We used an histological study of sciatic nerve; enzyme-linked immunosorbent assay and enzyme electrophoresis methods. In rats with DP, fragmentation of nerve tissue and their necrosis was established. Moreover, degraded forms of plasmin that has a fully functional serine proteinase domain are evident, and, therefore, it exhibits proteolytic properties. DP led to a decrease of neuron growth factor (NGF), vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF). After treatment, the histological structure of nerve tissue was significantly improved, and the expression of growth factors NGF and bFGF was increased. Our study demonstrated that administration of Corcarnit brought about the complete restoration of the activation potential of plasmin and the almost disappearance of all degraded forms which were evident in the group with DP.

Variations of TSNA Levels in Tobaccos Upon Heating at Moderate Temperatures
Authors: Moldoveanu Serban C. , Adams Marlene , St.Charles Frank K. 
Published: October 2020

Summary
Tobacco-specific nitrosamines (TSNAs) including nitrosoanabasine (NAB), nitrosoanatabine (NAT), 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), and nitrosonornicotine (NNN) are naturally present at trace levels in tobacco. During tobacco processing, preparation of expanded tobacco, and when tobacco is used in heat-not-burn type cigarettes, the tobacco is exposed to different degrees of heat. Heating of tobacco has been reported in the literature to increase the level of TSNAs. Since the increase of TSNAs in heated tobacco is still not well understood, the present study evaluated TSNA levels in six types of tobacco as a function of moderate heat exposure. These tobaccos included: flue-cured lower stalk, flue-cured upper stalk (US), Burley lower stalk, Burley upper stalk (US), and two Oriental blends (Turkey, Greece, Bulgaria, Northern Republic Macedonia). Heating was performed in sealed glass tubes at oven temperatures of 100 °C, 150 °C, 200 °C, and 250 °C for time intervals of 2 min and 5 min. The temperatures inside the glass tubes were lower than the targets and were monitored separately as a function of glass tube heating. The study showed no meaningful differences within tobacco type (by stalk position) but showed considerable differences in the levels of TSNAs between different tobaccos, with the Burley tobaccos having the highest levels, and the Orientals the lowest. For all tobacco types, TSNAs increase to some extent when temperature increases. For 2-min heating, the increase in TSNAs is relatively small up to about 200 °C, but the levels almost double when the oven temperature increases to 250 °C. For 5-min heating, the increase in TSNAs starts at about 150 °C with a maximum at 200 °C which can reach more than double the initial TSNA level. Longer heating at 250 °C (5 min) starts to cause TSNAs decomposition and the levels are reduced.
Influence of Landscape Diversity on Temporal Variability of Ecosystem Functioning in the South of Western Siberia

Published: October 2020

Abstract
Biodiversity increases the stability of ecosystem functioning. This is the most frequent pattern in the field of ecosystem functioning, which has been evaluated generally at the community scale. However, most management decisions are made at the landscape scale, which requires the need to confirm these relationships at this level. In the study, we analyzed the relationship between temporal variability of ecosystem functioning and two landscape diversity indices (Shannon and Pielou). We used snow water equivalent and soil moisture content as the indicators of functioning, which are closely related to the runoff formation function. The field data were collected in a small plain basin of the Kasmala river during the period from 2011 to 2017. Within four spatial scales, we have not identified significant linear relationships between the indicators of functioning and diversity indices. These results indicated the strong influence on the total variability by variation in the most widespread ecosystem types (also called idiosyncratic response). It is one of the consequences of landscape structure homogenization within the study area.

Labour Migration of Poles
Authors: Czapski Grzegorz 
Published: October 2020

Summary

Subject and purpose of work: The contemporary labour market in Poland is characterised by a large scale of migration of people, caused by the desire to find a good job. This situation is facilitated by the possibility of free movement within the European Union. The purpose of this study is to present the concept of migration, its types, causes and effects. Statistics related to the labour migration of Poles are also presented. The subject of the study is the migration activity of Poles abroad. The obtained data are presented using the descriptive method and graphical methods.

Materials and methods: National literature and statistical data were used during the work on the research problem.

Results: Statistics showing the scale of the migration phenomenon in Poland are presented. The research period covered the years 2013-2018.

Conclusions: Over the period under consideration, the number of Poles travelling abroad for work purposes decreased. This may be due to the decreasing number of unemployed people and the lower unemployment rate in Poland. At the same time, an increasing number of job offers in the national labour market can be observed.
Antioxidant potential and iodine accumulation in tomato (Solanum lycopersicum L.) seedlings as the effect of the application of three different iodobenzoates
Authors: Halka Mariya , Smoleń Sylwester , Ledwożyw-Smoleń Iwona 
Published: October 2020

Abstract
Iodine (I) has a beneficial effect on plant growth, development and antioxidant activity. The study aimed to compare iodine uptake after the application of iodobenzoates (2-iodobenzoic acid (2-IBeA), 4-iodobenzoic acid (4-IBeA) and 2,3,5-triiodobenzoic acid (2,3,5-triIBeA)) as well as potassium iodide (KI) to tomato seedlings. One of the main tasks was to evaluate how the tested compounds applied in different concentrations (5, 10, 25 and 50 μM) affect the growth and antioxidative potential of tomato seedlings. Negative effect on growth and development of tomato seedlings was noted for 4-IBeA applied in 10–50 μM I concentrations. The 2,3,5-triIBeA application affected shoot deformation. All tested iodine compounds increased iodine level in leaves and roots of tomato seedlings. Iodine after KI application was accumulated mainly in leaves, while after iodobenzoates treatment in roots of tomato seedlings, which is probably related to their weaker transport to the upper parts of the plant. Tested compounds variously modified the content of ascorbic and dehydroascorbic acids in tomato leaves depending on applied concentration. KI treatment improved ascorbate peroxidase activity, but all iodobenzoates decreased APX and catalase activity in leaves. 4-IBeA (5 μM I) and 2,3,5-triIBeA (25 and 50 μM I) increased guaiacol peroxidase activity in leaves. It can be concluded that mechanisms responsible for plant oxidative metabolism were variously affected by the iodine compounds and its concentration in the nutrient solution.

Abstract
This paper is based on a data set of more than 90 years of experience in cultivation of tree and shrub species of Far-Eastern origin at Järvselja Training and Experimental Forest District. The aim of the paper was to estimate the growth and yield of different tree and shrub species in Eastern Estonia. For this purpose, the height and breast height diameter of trees were measured and their cold hardiness estimated in summer 2019. Our study showed that many tree and shrub species of Far-Eastern origin grow quite well in the conditions prevalent in Eastern Estonia. These introduced species have importance mainly in park management.
The use of woody plants in Estonian and Livonian manor ensembles during the second half of the 17th century
Authors: Nurme Sulev 
Published: October 2020

Abstract
Not much is known about the 17th-century Estonian and Livonian landscape architecture. Most of the information is based on the descriptions found in historical archival and literary sources and on some of the well-known engravings. According to these, a common idea of that era's landscape architecture is that it was humble in scale and design, and was similar to the practice of late-medieval times when there was no space or ambition to grow woody plants in small gardens of castles. But when diving into the Swedish manor plans dating back to the last decades of the 17th century, it can be noted that the layouts of manorial hearts are inherent to the spatial design of early baroque, which is characterized by a landscape that has strongly been redesigned and includes a decorative garden, kitchen garden and a park. This article focuses on the spatial composition of Estonian and Livonian manor parks of the second half of the 17th century and observes the role of trees and their use in these landscapes. This article is based on the results of a study about the planning of baroque manor hearts Understanding the Role of 18th Century Estonian Manor Ensembles in Contemporary Planning and Conservation (Eesti 18. sajandi mõisaansamblid 21. sajandi maastikuplaneerimises: avastamine, mõistmine, tõlgendamine) which was carried out by the author of this article. The map analysis results deal with the spatial structure of manor ensembles and the observations made during the analysis. The article examines the possible ways of using woody plants in 17th-century Estonian manors while looking at the manor ensemble as an architectonic of early baroque. Based on the research results it can be said that by the last decades of the 17th century the wealthiest manors had already built manor hearts with a modest but a clearly baroque style layout which is characterized by a regular and symmetrical ensemble core, a garden axially connected to the main building and avenues heading into the landscape. This type of approach enables to broaden the common conception of the era's garden and park architecture in the manor hearts of Estonia and Livonia. Based on what is highlighted in the article it can be said that the tradition and practice of garden art that has shaped the image of Estonian landscape had already been developed by the end of the 17th century.
On Spatiality of Emotions
Authors: Landweer Hilge 
Published: October 2020

Summary
The paper argues that all emotions possess a spatial and objective, social character. We can gain access to them only insofar as we are affected by them in a felt-bodily way. Therefore, we need a conception of felt embodiment if we are to achieve a philosophical understanding of the spatial character of emotions. Different phenomena, ranging from the atmospheres of landscapes to shared and individual emotions, illustrate the theses concerning the spatiality of emotions and atmospheres, exemplified by the social contrast of emotions, among other things. The next step clarifies why we should distinguish between the emotion itself and the felt-bodily affection by the emotion. By means of distinctions between two types of felt-bodily or corporeal interaction, a unipolar and a bipolar form, we can gain a better understanding of the spatial character of emotions but also how resonances of emotions work. One result of our examination is that we can explain why positive collective emotions become more intense through shared bodily experience.
