Assessment of the quality of life in the regions of the Russian Federation
Authors: Oreshnikov Vladimir V. , Nizamutdirov Marsel M.
Published: January 2024

The article deals with the issues of assessing the quality of life in the regions of the Russian Federation. The article briefly analyzes the approaches in this area, showing that, despite a fairly extensive scientific and practical base, the assessment of the quality of life of the population and related issues remain an object of debate. The use of private indicators does not fully reflect the actual state and leads to contradictory assessments of the level of development of the country’s regions. Based on the formed preconditions, the list of directions and indicators within each direction reflecting the quality of life of the population was determined. In the aggregate, the final list included 25 indicators grouped into 6 directions — “Income and welfare of the population”, “Economy and labor”, “Health and safety”, “Education and culture”, “Trade and communications”, “Climate and geographical location”. The methodology of consistent aggregation of indicators and calculation of the integral assessment of the quality of life in the subject of the Russian Federation is developed. The weight characteristics of the indicators were determined. The rating of Russian regions by the quality of life of the population was formed, which allows us to analyze both its current structure and changes in the position of each region over a given period of time.
Exemption from liability of participants in public procurement: balance of interests of the parties
Authors: Zimneva Svetlana V. , Lukyanenko Marina F.
Published: January 2024

A noticeable increase in the number of state (municipal) contracts concluded every year hinders the contractual obligations’ fulfillment due to various circumstances beyond the control of the supplier. The state supports the stable functioning of the public procurement system by establishing anti-crisis measures, in particular, the obligation to write off the amounts of penalties (fines, penalties) accrued to the supplier, according to the decree of the Government of the Russian Federation No. 783. This article discusses the grounds and conditions for writing off penalties under state (municipal) contracts and analyzes judicial practice. The purpose of the study is to analyze the grounds for writing off accrued and unpaid penalties (fines, penalties) under government (municipal) contracts, to identify problems and features of the application of grounds for writing off penalties under government contracts, and to determine the interests of participants in public procurement. Based on the analysis of the current legislation and law enforcement practice, it was concluded that the write-off of accrued amounts of penalties (fines, penalties) by legal nature is a case of releasing the supplier from civil liability for violation of its obligations. Such exemption from liability is provided at the subordinate level, ensures a balance of public and private interests with an indefinite period of validity.

Authors: Ramankulov Kubanychbek S. , Zaytseva Larisa V.
Published: January 2024

The Declaration on the Establishment of the Shanghai Cooperation Organization proclaims the promotion of effective cooperation between the participating States in the trade, economic, scientific, technical, educational, energy, transport, environmental fields, as well as joint efforts to build a new democratic, just and rational political and economic international order. The authors explore the foundations and potential of the convergence of the labor legislation of the SCO countries as a necessary element of the new international order. Taking into account the existing differences based on the distinctive path of each country, the authors investigate the systems of labor legislation of the SCO member states in order to identify common and special characteristics of the systems of legal regulation of labor relations. The objective reasons for the development of economic ties are revealed, which actualize in the future the issues of transformation of labor law in the context of structural changes in the labor market and the development of new, non-standard forms of employment. Based on the analysis of the current regulatory legal acts and scientific research, the general features characteristic of the labor legislation of each country are summarized. The most acute issues of legal regulation of the employment contract are investigated. The author’s view is offered on the most topical aspects of the legal regulation of individual relations in the sphere of labor related to the development of non-standard forms of employment in the SCO countries. As a result, the conclusion is substantiated that there are common challenges for the existing systems of legal regulation of contractual relations in the field of hired labor, which means that there are potential opportunities for consolidating efforts to overcome the consequences of the changes that have arisen and developing common approaches to developing new and most effective ways of influencing the right to labor relations. Since the SCO Charter 2002 The socio-economic goals of the organization include, among other things, a steady increase in the level and improvement of the living conditions of the peoples of the member States, then the issues of contractual regulation of labor relations should occupy one of the defining places in the system of states’ efforts to achieve it.

“Lifeworld” in the coordinates of modern existential sociology
Authors: Andrianova Elena V. , Davydenko Vladimir A. , Chernenko Anzhelika S.
Published: January 2024

The aim is to study the possibilities and limitations of the definition of the "life world" in the content and semantic coordinates of modern existential sociology. Relevance: in the humanities, there is a "turn" — a turn towards "new existentialism", which is associated with the processes of "ontologization" of sociological science. In view of this, the definition of the "life world" acquires a special, non-trivial status for explaining and understanding the features of the modern existence of the individual and community. Objectives: the articles reinterpret the key ideas of existential sociology from the perspective of the difference between its subject and the subjects of other existential sciences — anthropology, psychology, philosophy, ethnography. Methodology — analysis of the principles, prerequisites, approaches, ideas of the leading representatives of the existential direction. Results: the author’s program has been developed, identifying the key parameters of the existential human model in sociology based on interpretations of the meanings of social reality considered through the prism of the coordinates of the social ontology of everyday life: individualism — collectivism; rational — irrational, using the conceptual and categorical apparatus: authenticity; situation; choice; actions; experience; feelings and emotions; self; body; structure; culture; religion, freedom, space and time; social changes, manifestations of being ("existentials"), massification, leveling. Theoretical and practical significance — the development of research algorithms that reflect individual and collective actions in the paradigm of the "life world", the presentation of a set of concepts in the chosen logic of presentation, which explains how and why existential sociology can be structured at macro-, micro- and meso- levels, can be presented in the middle range theories, in non-standard formats of visual, relational and sensory sociology; stated in negative and positive terms. The main methods are based on typical techniques of critical discourse analysis and frame analysis. Scientific novelty: despite the presence of various parameters of the life world and the corresponding modes of existence of individuals and communities, both these constructs themselves and their relationships have not yet been studied at sufficiently deep levels in the scientific community. The main conclusions of the article are the discovery of new conceptual spaces by existential sociological theory in the study of social mechanisms of synthesis of "soft" and "hard" versions of "structural bias", which explain the formation and determination of individual and group decisions by certain structural forces. The authors’ scientific contributions are in the fact that new possibilities of the definition of the "life world" are indicated to be presented in the coordinate framework of various sociological theories, including modern existential sociology.
Features of demand for educational services of higher education and assessment of its availability
Authors: Stol Anna V.
Published: January 2024

One of the characteristics of the quality of life is the degree to which the population meets social needs, including educational needs. The policy of access to education is part of the social policy of the state, it affects the process of human capital formation. The availability of higher education (the availability of state-funded places and the availability of paid educational services) tends to decrease. A decrease in the number of universities helps to improve the quality of admission while reducing the quality of the educational services themselves of higher education. As a result, there is a tendency to shrink the educational space of Russia following the compression of the economic space in the country’s large cities. This may contribute to increasing regional educational, technological and socio-economic inequality in the regions of the Russian Federation.

Dilemmas Faced by Polish Migrants in the UK Concerning Brexit and Return Migration
Authors: Fel Stanisław , Kozak Jarosław , Wodawski Marek , Isański Jakub
Published: January 2024

This paper presents the results of an original quantitative sociological study conducted in Autumn 2019 on a sample of 620 Polish migrants living in London, Oxford, and Swindon. The study was conducted using a group-administered questionnaire. It was primarily to address the question of whether they intend to return to Poland and when. We identify some significant factors influencing their choices. Those are the length of stay in England, their financial situation, their knowledge of English, their ability to assimilate culturally, their relations to the families in Poland, homesickness, and better religious education of children. Religious issues, although mentioned, are less critical; however, a deeper statistical analysis allows to understand the religious background more broadly, to provide a clearer image of the respondents’ deep motivations.

Authors: Fajriani Laksmi Nur , Sulaeman Ahmad , Setiawan Budi
Published: January 2024

Sumbawa wild horse milk is pure milk produced from Sumbawa horses with high nutritional content. It can survive for five months at room temperature without processing and has health benefits. However, the utilization of Sumbawa wild horse milk is still limited because of its low sensory quality due to natural fermentation, which also adversely affects its acceptability. Adding probiotic bacteria is one of the methods to improve its quality. This study aims to develop and analyze the physicochemical and sensory quality of probiotic drink products from Sumbawa wild horse milk by adding probiotic bacteria. This study used a one-factor, Completely Randomized Design (CRD), namely different types of starters. The treatment in this study is using probiotic starter Lactobacillus rhamnosus (P1) and commercial starter Lactobacillus bulgaricus + Streptococcus thermophilus (P2). The probiotic drink from Sumbawa wild horse milk in the treatment P1 has the best results, pH 4.35, 0.55% titratable acidity, 13.10% total dissolved solids, 78.00 mPa.s viscosity, 74.66% syneresis, and 3.42x109 CFU/ml total LAB. The most preferred product based on the hedonic test is P2. P2 has a whiter color and more sour taste. The addition of probiotic starters can improve the physicochemical product, and commercial starters can improve the sensory quality of the product.

Authors: Nakao Yuki , Thompson Errington , Mattingly Jared , Wolfer Rebecca
Published: January 2024

Cases of small intestinal diverticulosis are rare and mostly asymptomatic. Occasionally, a small bowel diverticulum may perforate. We describe the case of an 80-year-old male who presented with abdominal pain and signs of localized peritonitis. The ultimate diagnosis was confirmed to be perforated jejunum diverticula. Perforation of the jejunal diverticulum should be considered as part of the differential diagnosis of acute abdomen in elderly patients, and appropriate treatment options, ranging from early surgery to conservative measures, should be tailored to the patient's presenting condition and their overall physiology.

Background: The toddler period is a golden age for the formation and development of children starting from the basic sensory abilities, thinking, speaking, and intensive intellectual mental growth and early moral growth. So that the nutritional status of children under five is very, very important to study because it is related to the current increasing stunting status. Cases of stunting under five currently have the highest number when compared to other forms of malnutrition. The prevalence of stunting in DIY in 2018 was 12.37% and this figure fell to 10.69% in 2019 but in 2020 it rose to 11.08%. The highest prevalence of stunting is Gunung Kidul Regency (17.43) and the lowest is Sleman Regency (7.24). From this figure, it can be seen that the prevalence of very short toddlers in DIY is lower when compared to Riskesdas in 2018 (21.4%) (1).

Objectives: To determine the relationship between the characteristics (education, occupation) of the mother, provision time of weaning food, exclusive breastfeeding, and the provision of deworming drugs with nutritional status in toddlers aged 6-60 months in 2 areas, namely in the work area of the Pajangan Health Center and the Work Area of the Public Health Center, Sedayu.

Methods: Analytic survey with cross-sectional design. Analysis of the data using the chi-square test with a sample of 35 mothers who have children under five.

Results: The results showed that there was a correlation between the time of weaning food (p = 0.0001), history of exclusive breastfeeding (p = 0.0001), and the nutritional status of children under five. However, there was no correlation between education (p = 0.657), occupation (p = 0.579), deworming (p = 0.410).
Conclusions: There is a correlation between the time of weaning food, history of exclusive breastfeeding nutritional status in toddlers

Published: January 2024

Background: According to World The Health Organization (WHO) states that around 95% of children with developmental disorders live in the country income low and intermediate. Several studies show that stunting and being underweight are related to child development, especially motoric, cognitive, and language development on child. Psychosocial stimulation is external or environmental stimulation that is important for child development. Children who receive targeted and regular stimulation develop faster than children who receive less or no stimulation. If developmental deviations are not treated early and adequately, they tend to result in disability.

Objectives: To determine the relationship between maternal psychosocial stimulation and children development age 3th– 5th years in Gamping 1st Public Health Center Working Area.

Methods: The quantitative analytical research with design cross sectional. The sampling technique used is probability sampling with a type of cluster random sampling technique design with a total sample of 103 children from 1,421 in population at posyandu in Gamping 1st Public Health Center Working Area. Child development is measured using a Questionnaire Pre-Screening Development (KPSP). Psychosocial stimulation mothers were measured using the HOME instrument which has been tested by CVI Expert. The bivariate analysis used is the test chi square .

Results: Based on the research results after carrying out the Chi Square Test, the p value was 0.002  (p-value was <0.05).
Conclusions: That psychosocial stimulation has an relationship on children's development aged 3-5 years this is also one of the nurturing patterns that mothers can do at home. The need for further research is to control the amount or how much influence from outside regarding the information obtained by the mother which can influence the level or model of stimulation that the mother develops when providing stimulation

Published: January 2024

The purpose of this study was to assess school-based supervision and school performance in secondary schools of Guraghe Zone. To conduct this study, a correlational research design was employed. One Zonal and three District Education Office supervision coordinators were selected through the availability sampling technique. Among the 77 government secondary schools found in the Zone, 10 of them were selected randomly as sample schools. From these sample schools, 10 principals and 10 school-based supervisors (10 unit leaders and 50 heads of department) were also included as respondents using the availability sampling technique. Furthermore, 286 teachers have participated in the study through purposive and availability sampling techniques. Questionnaires and document analysis were tools for collecting data in the stud. Frequency, percentage, mean, and t-test were utilized to analyze quantitative data gained through the questionnaires. The qualitative data gathered through document analyses were by narration. The results of the study indicated that teachers lack awareness and orientation on the activities and significance of school-based supervision, ineffectiveness of the practice of supervisory options matching with the individual teacher’s developmental level, and the inability of supervisors to apply the necessary procedures for classroom observation properly. This all was due to the following factors influencing such as lack of relevant training programs for supervisors, scarcity of experienced supervisors in school-based supervision activities, lack of supervision manuals in the schools, and shortage of allocated budget for supervisory activities, and that also leads to low school performance. Finally, to minimize the problems of school-based supervision and low school performance in secondary schools, it is recommended to give relevant in-service training for supervisors to upgrade their supervisory activities, necessary resources such as supervision manuals, and an adequate budget for the success of supervision at the school level were suggested so that schools can perform in a good manner.
BENEFITS OF LITHIUM MINING TO NIGERIA’S ECONOMIC DEVELOPMENT
Authors: CLINTON EBIKEMEFA EBIMOBOWEI , BASU MARTINS
Published: January 2024

Lithium mining goes beyond the extraction of lithium ore; it involves the technological importance of the mineral together with its application. This refers to eco-friendly applications such as the production of electric cars, the production of lithium batteries for solar panels, and other electrical devices. Obtained lithium (spodumene) samples from visited mine sites in Gidan Kwano (Nasarawa State), Kokona (Nasarawa State), and Takushara (Abuja-Kuje LGA) were taken to the laboratory for analysis. The atomic absorption spectrometry result shows a lithium percentage that ranges from 1% to 4.5% (low to high grade). A statistical analysis of data for total production of lithium in a month (through interactive sessions with miners on-site) shows that over 20 tons of lithium can be produced in a month by an active lithium mine site. Conclusively, if 20 tons is used as the benchmark, this means that a total of 40 trucks worth ₦20,375,000,000 will be made per month and a total of ₦244,500,000,000 per year. With this amount of money, after the removal of various royalties, it can go a long way in handling various issues in the state, local government, and even at the federal level. Well-monitored lithium mining can create jobs for indigenous people in the community, and the financial contribution can increase the internally generated revenue. The production of electric cars in Nigeria will also help solve the issue of carbon emissions and create a friendly eco-system.
UPGRADING EFL LEARNERS’ SPEECH SKILLS USING ELECTRONIC DICTIONARIES AND PODCASTS
Authors: Suseno Edy
Published: January 2024

The majority of EFL students have trouble expressing their opinions. Poor hearing, pronunciation, and vocabulary skills are the causes of it. They used electronic dictionaries and podcasts to promote conversation so they could help repair it. An application of WhatsApp group was made to begin the course. On the screen, the instructor displayed the podcast’s URL. The content of the dialog and monolog was then taught to the students. To understand them both in the text and the audio, it was advised that they use their electronic dictionaries. The instructor then extended an invitation to the pupils to use the Google Meet tool. He gave them the task of locating the transcript’s examples of real-life issues. The students were then asked to propose possible fixes for the problems. Following the discussion, the teacher provides feedback on the students’ presentations in the WhatsApp group. The interaction with podcasts and electronic dictionaries helped students develop their speaking skills, according to a qualitative examination of the questionnaire responses and information gathered from the observation. These insights can be used by the teachers to include the relevant subject matter in their lessons. It also encourages additional researchers to conduct pertinent research.

ISTHMIAN CENTRAL AMERICAN FROGS WITH DIFFERENT BIOFLUORESCENCE PATTERNS
Authors: Garcia Castillo Mirna Grisel , Basanta M. Delia
Published: January 2024

Biofluorescence is the fluorescent glow in blue, green, and red colors that organisms emit when exposed to blue or ultra-violet light. This phenomenon has been documented in different animal groups, the most recent finding being in amphibians. The function of biofluorescence in amphibians is still unknown, although it is hypothesized that it may be associated with sexual selection, communication, and visual acuity. In this work, we described the biofluorescence patterns for six species of anurans occurring in Isthmian Central America. Likewise, five species that did not react with fluorescence to the stimulus of blue light are also mentioned. Because in some works there are inconsistencies regarding the presence or absence of biofluorescence between species, we recommend the use of blue light of 440–460 nm and a yellow #12 filter, which have been successfully tested for the detection of biofluorescence in amphibians.

Quantum Kolmogorov complexity and quantum correlations in deterministic-control quantum Turing machines
Authors: Lemus Mariano , Faleiro Ricardo , Mateus Paulo , Paunković Nikola , Souto André
Published: January 2024

This work presents a study of Kolmogorov complexity for general quantum states from the perspective of deterministic-control quantum Turing Machines (dcq-TM). We extend the dcq-TM model to incorporate mixed state inputs and outputs, and define dcq-computable states as those that can be approximated by a dcq-TM. Moreover, we introduce (conditional) Kolmogorov complexity of quantum states and use it to study three particular aspects of the algorithmic information contained in a quantum state: a comparison of the information in a quantum state with that of its classical representation as an array of real numbers, an exploration of the limits of quantum state copying in the context of algorithmic complexity, and study of the complexity of correlations in quantum systems, resulting in a correlation-aware definition for algorithmic mutual information that satisfies symmetry of information property.
Parameter Setting in Quantum Approximate Optimization of Weighted Problems
Authors: Sureshbabu Shree Hari , Herman Dylan , Shaydulin Ruslan , Basso Joao , Chakrabarti Shouvanik , Sun Yue , Pistoia Marco
Published: January 2024

Quantum Approximate Optimization Algorithm (QAOA) is a leading candidate algorithm for solving combinatorial optimization problems on quantum computers. However, in many cases QAOA requires computationally intensive parameter optimization. The challenge of parameter optimization is particularly acute in the case of weighted problems, for which the eigenvalues of the phase operator are non-integer and the QAOA energy landscape is not periodic. In this work, we develop parameter setting heuristics for QAOA applied to a general class of weighted problems. First, we derive optimal parameters for QAOA with depth p=1 applied to the weighted MaxCut problem under different assumptions on the weights. In particular, we rigorously prove the conventional wisdom that in the average case the first local optimum near zero gives globally-optimal QAOA parameters. Second, for p≥1 we prove that the QAOA energy landscape for weighted MaxCut approaches that for the unweighted case under a simple rescaling of parameters. Therefore, we can use parameters previously obtained for unweighted MaxCut for weighted problems. Finally, we prove that for p=1 the QAOA objective sharply concentrates around its expectation, which means that our parameter setting rules hold with high probability for a random weighted instance. We numerically validate this approach on general weighted graphs and show that on average the QAOA energy with the proposed fixed parameters is only 1.1 percentage points away from that with optimized parameters. Third, we propose a general heuristic rescaling scheme inspired by the analytical results for weighted MaxCut and demonstrate its effectiveness using QAOA with the XY Hamming-weight-preserving mixer applied to the portfolio optimization problem. Our heuristic improves the convergence of local optimizers, reducing the number of iterations by 7.4x on average.

approximately 11.5 m s-1 and wavelengths ranging from 60 to 90 km. These
gravity waves are generated by the interaction between a
northwest-southeast direction mountain (Funiu Mountain, FNM) and a
southwesterly flow originated from the mesoscale convective vortex (MCV)
developing from an inverted trough southwest of the rainfall center.
Then, these waves propagate northeastward through a wave duct featuring
a stable layer between 5 and 9 km altitude, capped by a low-stability
reflecting layer with a critical level. As they propagate, these waves
trigger banded convective cells along their path. Upon the arrival of
gravity wave peaks at the rainfall center, they induce the downward
energy flux of gravity waves from high troposphere levels
(~7 km). The downward wave energy dynamically interacts
with the upward wave energy from gravity waves excited by latent heating
at the lower tropospheric level (~1 km). This
synergistic effect intensifies the ascending motion and results in a
precipitation increase of over 20% at the rainfall center. This study
highlights the significance of orographic gravity waves in shaping
extreme precipitation events.

GSD (grain size distribution), constitutes a paramount parameter for
comprehending the behavior and dynamic mechanics of mass movements, such
as debris flows, rock avalanches, sediment transport etc. Alongside
traditional sieving methodologies, the past few decades have witnessed a
growing interest in photo-sieving, the technique of deducing GSD
directly from photographic data. Photo-sieving holds promise for
augmenting the spatial and temporal resolution of superficial GSD
analysis by virtue of its accessibility, reduced labor intensity, and
non-invasive nature. Moreover, the integration of aerial photography
within the discipline enables to include the coarse-grained fraction,
expanding the scope of particle size analysis beyond the capabilities of
traditional sieving. This study introduces a novel algorithm for
extracting the coarse-grained fraction using UAV (unmanned aerial
vehicle) photography. This novel approach enables us to analyze
hectare-scale extents, probing tens of thousands of clasts - surpassing
previous similar techniques by two orders of magnitude - and generates a
detailed map of the position and dimensions of each particle within the
sedimentary system. Furthermore, the algorithm exhibits remarkable
resilience in navigating real-world complexities, effectively discerning
clasts from vegetation, anthropogenic artifacts, and handling
exceptionally large boulders, rendering it suitable for application in
diverse field settings. We anticipate that this technique could become a
valuable tool for advancing our understanding of debris flow and rock
avalanche dynamics, sediment transport processes, and the stability of
landslide dams.
Marine phosphate level during the Archean constrained by the global redox budget
Authors: Watanabe Yasuto , Ozaki Kazumi , Tajika Eiichi
Published: January 2024

Understanding the oceanic phosphate concentration is critical for
understanding marine productivity and oxygen evolutions throughout Earth
history. During the Archean, estimates of marine phosphate levels range
from depleted to enriched conditions. However, biogeochemical conditions
required for sustaining high phosphate concentrations while retaining an
anoxic atmosphere during the Archean remain ambiguous. Here, we employ a
biogeochemical model of the marine phosphate cycle to determine the
conditions under which oceanic phosphate levels could have been higher
than present-day values during the Archean after the emergence of
oxygenic photoautotrophs. We show that, under the presence of oxygenic
photoautotrophs, phosphate-rich oceans require the limitation by factors
other than phosphate, or a combination of ocean stagnation and a high
outgassing rate of reducing gases. If these conditions were not met, the
occurrence of oceanic phosphate levels higher than present-day values
during the Archean would require the absence of oxygenic
photoautotrophs.

Ekspedīcijas un pētījums ir veikts projekta Nr. LLI-444 “Jaunu ilgtspējīgu risinājumu integrācija kultūras mantojumā/ NovelForHeritage” (Aktivitāte: T.1.5. Research of historical materials and knowledge on G.Kuphaldt parks and gardens and creation of the set of materials) ietvaros, kas tiek realizēts Eiropas Reģionālās attīstības fonda (ERAF) Interreg V-A Latvijas – Lietuvas pārrobežu sadarbības programmā 2014-2020. gadam. Šis pētījums ir sagatavots ar Eiropas Savienības finansiālo atbalstu. Par šī pētījuma saturu pilnībā atbild Latvijas Biozinātņu un tehnoloģiju universitāte un tā nekādos apstākļos nav uzskatāma par Eiropas Savienības oficiālo nostāju. Ekspedīciju laikā izdevās apmeklēt parkus un dārzus trīs valstīs – Latvijā (Rīga, Liepāja, Eleja, Pelči, Kazdanga), Lietuvā (Pakroje, Žagare, Šeduva), Igaunijā (Oustvere un Pērnava). Parkus, kas atrodas privātā īpašumā, daļēji nebija iespējams apmeklēt, dēļ ierobežotas piekļuves. Apmeklētajiem parkiem ir veikta padziļināta parku analīze - parka veidošanās vēsture, parka telpiskā struktūra, dendroloģiskais sastāvs, arhitektoniskie elementi un parka mūsdienu funkcionālā izmantošana. Šī pētījuma mērķis ir analizēt Kūfalta plānotos un realizētos parkus no to ainavas telpiskā viedokļa, kas no tā ir saglabājies mūsdienās, kā parki spēj pielāgoties mūsdienu funkcionālajai izmantošanai. Pētījuma gaitā tika atlasīta informācija par parku un muižu vēsturi, par pašiem parkiem un apstādījumiem vai to plānojumiem. Pētījuma ietvaros izmantoto informācijas avotu klāsts iekļauj vēsturiskās grāmatas, attēlus, plānus, kā arī aprakstus. Plašs apkopojums par Rīgas parkiem ir Latvijas Nacionālas bibliotēkas fondā, savukārt par muižu parkiem Māras Ilzes Janelis grāmata vēl joprojām ir favorīts, analizējot muižas parku veidošanās vēsturi, kā arī tipiskās kļūdas un ieteikumus vēsturisko parku apsaimniekošanai un plānošanai. Ir izdevies arī turēt rokās un lasīt Kūfalta rakstīto grāmatu “Die Praxis der angewandten Dendrologie in Park und Garten”, kas ir praktisks ieskats augu sortimentā, ko Kūfalts izmantoja savos plānojumos. Pētījumā Kūfalta darbi sadalīti pa funkcionālajām grupām, lai vieglāk analizēt un izprast katra apstādījumu un teritoriju specifiku, pielāgošanās iespējas un tūrisma potenciālu. Lielās grupas - muižu parki, pilsētu parki un skvēri, kūrortu apstādījumi - lineārie parki. Katrai apstādījumu grupai ir sava plānošanas specifika, savi raksturīgie elementi un funkcijas.

Published: January 2024

Existing civil engineering structures, especially masonry structures are subjected to heavy loads dynamic, well reflected vibration in the generated processes. These vibrations can affect the condition of the works by reducing the comfort of people working there, as they can reach the level of endangering the safety of the structure. The effect of vibration on the structure manifests itself mainly as an additional stress in the present section, which add to the stress of static loads. In addition, there is often of the effects of climate-related environment, with fatigue - dynamize destruction of the object. Dynamic loads can cause devastating effects in buildings of various types of construction or lead to catastrophic destruction.

This article presents a modern methodology for non-invasive testing of masonry structures using vibration processes. Here is shown the possibility of using modal analysis methods to assess the state of destruction elements and masonry using the process of vibration and vibration measurement. This is a new approach, using innovative research methods supported by information technologies, to examine the suitability of building materials, and the conditions for the construction of a diagnostic agent.
Sustainable living environment in the context of social needs
Authors: Kołacz Katarzyna
Published: January 2024

A sustainable living environment should be shaped in an ecological, economic and pro-social way. The aim of this work is to draw attention to this last, often overlooked aspect in the context of designing sustainable residential architecture, what can be achieved by taking care to maintain social relations at the appropriate level. The article reviewed the existing theories of sociologists, psychologists and architects on the features of architecture and residential spaces. The analysis of literature sources showed that there are architectural elements that can support the formation of social contacts. On their basis, a set of ten evaluation criteria was developed, which can be used for further research, e.g. in the context of evaluating pro-social solutions in selected architectural and urban projects.

W opracowaniu badano zmiany w sektorze ogrodniczym w Polsce w latach 1960-2012. Badania wykazały, że warunki społeczno-ekonomiczne i klimatyczno-glebowe sprzyjały rozwojowi ogrodnictwa, które odgrywało coraz większą rolę w polskim rolnictwie. Udział upraw ogrodniczych w UR wzrósł z 2,3% do 3,9%, a w towarowej produkcji roślinnej z 22,5% do 52% (w tym kwiaciarstwa z 5% do 21,8%). Udział produktów ogrodniczych w eksporcie rolno-spożywczym wynosi około 13,6% i obniża się od początku lat 90. XX w., w imporcie zaś jest na poziomie 15-20%. Dalszy rozwój ogrodnictwa determinowany będzie głównie wzrostem eksportu.
