Abstract
This experiment was carried out to evaluate the nutritive value of nine Pennisetum purpureum varieties as ruminant feed, with the application of organic manures. The research was 3×9 factorial arrangement in a split plot design. Experimental P. purpureum included Abeokuta 1, Abeokuta 2, F1 Hybrid, Green Local, Purple Local, Sugarcane, South Africa, S13 and S15, and three manure types (control, swine and cattle). Results showed that the P. purpureum fertilised with cattle dung had (p < 0.05) higher dry matter (91.92 %), crude protein (CP) content (9.78 %) and neutral detergent fibre (NDF) content (61.10 %) than other treatments. Fi hybrid variety recorded the highest CP (8.93 %) and lowest NDF (57.80 %) contents and purple local variety had the least CP (8.37 %) content. Cattle dung fertilised grasses recorded higher calcium (8.77 g/kg) and phosphorus (2.06 g/kg) content compare to its counterpart, South Africa variety of P. purpureum recorded the highest (9.81 g/kg) Ca content. This study shows that farmers who value high‐quality feed would benefit from the cultivation of F1 hybrid variety of P. purpureum and cattle dung is recommended for the fertilisation of the varieties evaluated.

Abstract

Aim. Vitamin D is currently an exciting research target, besides its obvious role in calcium homeostasis and bone health, enormous work is being directed at examining the effects of this vitamin on various biological functions and pathological conditions.

Material and methods. The review of the literature and the analysis took about six months and was carried out through PubMed. This is a search engine opening mainly the MEDLINE database of trusted references. We called up all studies written in English that were published between the years 2004 to 2021 and that came through using the applied search terms, and analysed all those that met the criteria.
Results. The endocrine system with its many glands and hormones and their essential roles in the maintenance of normal body functioning cannot be far from interactions with vitamin D. Male and female sex hormones are no exceptions and many studies have investigated the correlations between these hormones and vitamin D. As such, direct and indirect relationships have been found between vitamin D, its receptors or one of its metabolising enzymes with sex hormones and the development of reproductive organs in males and females.

Conclusion. This review summarises the research investigating the associations of vitamin D with sex hormones and reproductive organs in males and females, and thus may pave the road for future studies that will investigate the clinical significance of vitamin D in the management of reproductive system disorders. Despite some conflicting results about the relationship between VD and the effectiveness of the reproductive system, many studies confirm the presence of receptors for this vitamin in the reproductive system, and this supports the direct or indirect relationship between VD and prolactin or VD and testosterone through PO4 and Ca2+ homeostasis, or production of osteocalcin. Therefore, VD is positively associated with semen quality and androgen status. Furthermore, a direct relationship between VD and the production of progesterone, estrogen and estrone in human ovarian cells has been supported by many studies.
The mechanism of action of platelet-rich plasma – composition analysis and safety assessment
Authors: Lichtarska Anna Maria , Sokol Malgorzata Maria 
Published: December 2021

Abstract
Aesthetic medicine is an intensively developing field, more and more focused on stimulating and regenerating the skin, rather than on emergency treatment. There are many methods used by doctors for biostimulating therapies, but the most popular procedure in recent years is the implantation of platelet-rich plasma (PRP) used to date successfully in ophthalmology, dermatology, surgery, dentistry and even in orthopedics. The procedure uses autologous material, and its essence is a repair action on damaged cells of the patient as well as the activation of healthy cells and their stimulation for more effective work. The aim of the paper is to present current knowledge about platelet-rich plasma therapy in anti-aging treatment, the effectiveness of therapy with its use, and the mechanism and safety of PRP. The composition of the autologous preparation and its use in aesthetic medicine were also analyzed.
PRP is a procedure that uses the patient’s own cells, and growth factors are of key importance in the process of skin regeneration and biostimulation. The correctly performed procedure, including the appropriate collection and administration of a buffy coat to the patient and compliance with all the rules of sterility, results in positive effects of the therapy. Numerous studies prove the effectiveness and safety of the platelet-rich plasma treatment.
Highly concentrated platelets in the deposited preparation stimulate the surrounding cells to angiogenesis, differentiation, proliferation and synthesis of components essential for remodeling of the treated area. The therapy is highly effective and safe to use.

Published: December 2021

Abstract
Implementing a large genomic project is a demanding task, also from the computer science point of view. Besides collecting many genome samples and sequencing them, there is processing of a huge amount of data at every stage of their production and analysis. Efficient transfer and storage of the data is also an important issue. During the execution of such a project, there is a need to maintain work standards and control quality of the results, which can be difficult if a part of the work is carried out externally. Here, we describe our experience with such data quality analysis on a number of levels - from an obvious check of the quality of the results obtained, to examining consistency of the data at various stages of their processing, to verifying, as far as possible, their compatibility with the data describing the sample.

On Roach’s Presuppositional Response to Licona’s New Historiographical Approach
Authors: Erasmus Jacobus , Licona Michael R. 
Published: December 2021

Abstract
In a recent article, William C. Roach (2019) offers a presuppositional critique, which is inspired by Carl F. H. Henry, of Michael R. Licona’s (2010) so-called New Historiographical Approach (NHA) to defending the resurrection. More precisely, Roach attempts to defend six key theses, namely, that (1) the NHA is an evidentialist approach, (2) the NHA is a deductive argument, (3) the NHA is an insufficient approach, (4) believers and unbelievers share no common ground, (5) the NHA does not embrace a correspondence theory of truth, and (6) the presupposition of divine revelation is necessary for apologetics. We respond to each of Roach’s arguments, respectively.
A Critical Examination of the Church’s Reception of Emperor Constantine’s Edict of Milan of AD 313
Authors: Mutie Jeremiah 
Published: December 2021

Abstract
Since its enactment in AD 313, the Edict of Milan (sometimes referred to as ‘the Edict of Toleration’), an edict that freed Christianity from empire-wide persecution, Constantine’s declaration has received a significant amount of attention within Christendom. Most of the discussion has centered on Constantine’s conversion, the precursor to the actual edict (whether the conversion was real or insincere, as some have suggested), with many suggesting that Constantine was acting more as a politician than a Christian. While this line of inquiry is legitimate, perhaps a better approach to the question may be more helpful to present-day Christians. That is, while it is logical to deduce that every prudent politician will ignore the largest religious movement in his/her time at his/her own peril, Christians of every age will be better served if they critically evaluate their reception of each and every major policy that is clearly aimed at their benefit. With this background, this paper will attempt to critically examine the reception of Constantine’s edict by the Church in the years immediately following its enactment. Two early exhibits will be brought to bear here: the Donatist controversy and the Arian controversy. In so doing, the thesis that while Christians had every reason to celebrate the enactment of the edict, down the road, an uncritical adoption of the emperor’s policies and favors towards the church opened a door for an unhealthy marriage between earthly powers and the church that proved detrimental in the ensuing years, will be defended. As such, the Church’s reception of the Edict of Milan continues to be a lesson to Christians of every age in their relationship with the political leadership of their time.
Nourishment in Paradise and After Resurrection: Double Creation According to Gregory of Nyssa
Authors: Marunová Magdalena 
Published: December 2021

Abstract
Gregory of Nyssa (cca 335–cca 395), one of the three Cappadocian Fathers, introduces the creation of human beings on the basis of Genesis 1:26–27 and interprets these two biblical verses as a ‘double creation’—the first of which is ‘in the image of God’ (Genesis 1:26) and secondly as male or female (Genesis 1:27). His concept of ‘double creation’ is obviously inspired by Philo of Alexandria, a first-century Jewish philosopher, but Gregory points out the condition of human beings before and after committing the sin, in contrast to Philo’s conception. While Philo distinguishes between the first and the second creation of the entirety of nature, Gregory only relates the double creation to humans. Thus plants as nourishment for humans, according to Genesis, must be matched with the second creation of humans. In the resurrection, when the ‘first creation’ of human nature will be reached, human beings with their restored bodies will only feed on immaterial, spiritual food—the Word of God.
Analyzing the Influence of Metro Stations on Commercial Property Values in Delhi: A Hedonic Approach
Authors: Singhal Shaleen , Tyagi Yogesh 
Published: December 2021

Abstract
The effect of proximity to a transit system on property values has become a key issue of debate regarding public infrastructure and economic development. This article aims to examine the impact of selected stations along the Blue line of Delhi Mass Rapid Transit System (MRTS) on commercial property prices. The research analyzed 1,413 commercial property parcels sold before and after the commissioning of Blue line in 2005. Hedonic Price Analysis (HPA) was used to estimate the effects of proximity to the metro rail on commercial property values. The method was applied to two time periods, i.e., from 2000-2004 and 2005-2008, coinciding with planning and construction (pre-commissioning phase and the operation phase (post-commissioning phase) of metro rail using actual sale prices of commercial units. The results indicate that a station node shows a negative trend during the planning and construction period. However, the operation period has produced a significant price premium associated with commercial properties, connected with improved accessibility. The coefficients indicate that MRTS has induced an increase in prices from INR 732.80 to INR 246.19, and its radius of impact covers an area of approximately 1/2 km from the stations. The methodology and results provide insight with a specific focus on commercial real estate values in other metropolitan cities developing and expanding MRTSs.
The Application of Spatial Autoregressive Models for Analyzing the Influence of Spatial Factors on Real Estate Prices and Values
Authors: Kobylińska Katarzyna 
Published: December 2021

Abstract
The spatial distribution of real estate in specific geographic locations, real estate transactions, and the prices and values of properties are a highly complex spatial phenomena that should be analyzed with the use of multidimensional methods. Spatial factors are taken into account in the modeling process to increase the reliability of real estate market analyses, and spatial autoregressive models are applied to determine the effect of spatial factors on real estate prices and values.
The present study relies on a review of the literature and the results of an experiment. The concept and principles of market analysis were designed with the use of spatial autoregressive models, and the influence of selected spatial factors on real estate prices was presented on maps. Analyses involving autoregressive models enable reliable modeling and support correct interpretation of the observed processes.
Detection of periodic displacements of shell structures with edges using spline surfaces, meshes and point clouds
Authors: Lenda Grzegorz , Abrachamowicz Katarzyna 
Published: December 2021

Abstract
This research paper tackles the problem of determining displacements of complex-shaped shell structures, measured periodically using laser scanning. Point clouds obtained during different measurement epochs can be compared with each other directly or they can be converted into continuous models in the form of a triangle mesh or smooth patches (spline functions). The accuracy of the direct comparison of point clouds depends on the scanning density, while the accuracy of comparing the point cloud to the model depends on approximation errors that are formed during its creation. Modelling using triangle meshes flattens the local structure of the object compared to the spline model. However, if the shell has edges in its structure, their exact representation by spline models is impossible due to the undulations of functions along them. Edges can also be distorted by the mesh model by their chamfering with transverse triangles. These types of surface modelling errors can lead to the generation of pseudo-deformation of the structure, which is difficult to distinguish from real deformation. In order to assess the possibility of correct determination of deformation using the above-mentioned methods, laser scanning of a complex shell structure in two epochs was performed. Then, modelling and comparison of the results of periodic measurements were carried out. As a result of the research, advantages and disadvantages of each method were identified. It was noticed that none of the methods made it possible to correctly represent all deformations while suppressing pseudo-deformation. However, the combination of their best qualities made it possible to determine the actual deformation of the structure.
GHG Emissions Assessment as Part of MSW Green Cluster Design: Case of Large Cities in Russia and Kazakhstan

Published: December 2021

Abstract
The increasing pressure on the environment and the exhaustion of non-renewable natural resources has led to the emergence of a new type of clusters – green clusters. In green clusters, the purpose of combining entities into a cluster is not only to increase their competitiveness, but also to increase the efficiency of using natural resources and reduce the impact on the environment. Companies of various types of activities get united into green clusters; this article considers green clusters in the field of municipal solid waste (MSW) management. The authors described two green clusters in project in the field of MSW management in two large cities – Yekaterinburg (Russia) and Almaty (Kazakhstan). The main difference between these clusters is the ratio between waste management practices. Further, using the IPCC methodology for calculating greenhouse gas (GHG) emissions, the authors analysed GHG emissions per tonne of MSW in both clusters. The calculations have shown that the green cluster of Yekaterinburg is more stable and efficient – the carbon content of 1 tonne of processed MSW in Yekaterinburg is 22.4 % lower than it is in Almaty (329.5 kg CO2eq/tonne of MSW in Yekaterinburg and 424.1 kg CO2eq/tonne of MSW in Almaty). To reduce the MSW green clusters’ climatic impact, it is necessary to organize a full-fledged separate collection of different types of waste at the household level; to stimulate waste recycling activities; to reduce the use of non-recyclable packaging, including the implementation of extended producer responsibility; to reduce energy utilization, especially at the waste incineration plants; to stimulate the use of organic waste shredders. The practical examples discussed in this article and the conclusions obtained can be useful to decision makers regarding the design and development of green clusters in the field of MSW management in large cities. The study relies on the research data of the project ‘Enhancement of the State Regulation Policy for Intensifying Clusterization of Industrial Regions’ supported by the Ministry of Education and Science of the Republic of Kazakhstan.

Published: December 2021

Abstract
Biodiplomacy involves searching for a delicate balance and establishing a dialogue on the necessity to achieve international goals to develop the bioeconomy. The substantive basis of biodiplomacy is understanding bioresources, technological solutions for their extraction and use, indicators, and evaluation possibilities. The article is devoted to the establishment of a biodiplomatic institution. Such institutions will help young specialists in various economic sectors to develop competence approaches, acquire knowledge and build awareness that will make them competent to solve problems related to bioeconomy development and future, looking for efficient use of bio-resources and high value-added production. The aims and objectives of biodiplomatics are ambitious, which means that forms of study training must be attractive and multi-layered. Thus, the authors have analysed formative work assessment in the form of group work. With the help of a role game, the participation of different sections of society in developing the bioeconomy in agriculture, forestry and aquaculture was simulated. The article is devoted to the situation analysis, creating a model for building competencies, awareness, and knowledge of biodiplomats, and approbating it in the formative assessment work of the Riga Technical University bachelor’s study program in environmental engineering, organised as a role game.

Authors: Rozentale Liga , Blumberga Dagnija 
Published: December 2021

Abstract
In the last decade the European Union (EU) has been steadily increasing its’ ambition regarding the climate policy. Considering the linkage between the climate targets and energy sector’s greenhouse gas emissions, the EU’s member states are respectively adjusting their energy policies. One of the current trends in the EU is to increase the renewable electricity generation by roll-out of onshore and offshore wind parks. This research aims at evaluating the potential of large-scale wind parks in Latvia by using the cost-benefit and multi-criteria analysis from financial, technical, climate and administrative perspectives as well as considering the impact on security of energy supply. The results of the research show a good potential for onshore wind park development in Latvia without any state aid, while offshore wind parks are in a much worse position and would not be beneficial for the project promoters without any kind of EU or state aid.
COVID-19 Effects on Cultural Heritage: The Case of Villa Adriana and Villa D’Este

Published: December 2021

Abstract
The paper aims to provide a clarification of assessing insurance risk related to an asset owned by a subject under public law and, more specifically, to an economic cultural asset. This study is aligned with key aspects proposed by the EU for the protection of the cultural heritage from natural disasters. In the first place, given the peculiarity of the material inherent to cultural heritage, a motivation underlies the search for the correlation between the latter and the commonality. Secondly, it appeared necessary to verify the differences, similarities and importance of the economic management of cultural heritage in order to understand the social, economic, material and intangible importance of an asset managed in an economic way within a social axis (municipality). The third reason relates to the general severity and the risk and subsequent damage that a hazard, such as a pandemic outbreak (COVID-19), can cause on one or more cultural heritage. In the final analysis, perhaps the most meaningful aspect underlies the verification of the possible consequences in the analysis of summations of losses generated by a hazard in order to allow a prospect of what could be the consequences of such a catastrophic scenario.
