Authors: Matijasevic Srdjan , Topalovic Vladimir , Grujic Snezana , Savic Veljko , Nikolic Jelena , Labus Nebojsa , Zildzovic Snezana
Published: October 2021

The selected lithium germanium-phosphate glass was prepared by a conventional
melt-quenching technique. The XRD method was employed to confirm the glass
was obtained and to reveal crystalline phases during heat treatment. The
dilatometry (DIL), differential thermal analysis (DTA), and differential
scanning calorimetry (DSC) were used to determine the characteristic
temperatures and enthalpies of crystallization and melting of the
crystalline phase. The DTA and DIL were used to obtain the viscosity curves
by applying the Vogel-Fulcher-Tammann (VFT) equation
Optical properties of zigzag nickel nanostructures obtained at different deposition angles
Authors: Potocnik Jelena , Popovic Maja
Published: October 2021

In this study, nickel (Ni) thin films were deposited at two different angles
(65o and 85o) using Glancing Angle Deposition technique, to the thicknesses
of 60 - 290 nm. Structural analysis of the deposited films was performed by
scanning electron microscopy and X-ray diffraction, while spectroscopic
ellipsometry was used for the investigation of optical properties.
Electrical resitivity of the samples was determined by four-point probe
method. Structural analysis showed that the Ni films grow in a shape of
zigzag nanocolumns, where the deposition angle strongly affects their
porosity. As the thickness of the films increase they absorb light strongly
and become less dense. Besides, samples deposited at the angle of 85o
exhibit higher values of electrical resistivity as compared to the samples
deposited at the angle of 65o, which can be correlated with high porosity
and the growth mechanism of the deposited nanostructures.

Authors: Radosavljevic-Mihajlovic Ana , Mitic Vojislav , Saponjic Aleksandra , Kasic Vladan
Published: October 2021

Data on thermally induced transformations of Mn exchanged zeolites LTA and
FAU topology are presented in this paper. Thermally induced phase
transformation of Mn-exchange zeolites are followed in the range from 700 to
1300?C. Both frameworks collapse into amorphous intermediate products after
heating between 600 and 650?C. Prolonged heating of the intermediate
product above 1100?C results directly in formation of a disorder
Mn-anorthiteLTA and Mn-anorthiteFAU. The parameter of unit cell of
Mn-anorthiteLTA and Mn-anorthiteFAU, in temperature range between 700 and
1300?C, was observed in space group C-1. The phase conversions in the
temperature range investigated were followed by thermal, X-ray powder
diffraction and FT-IR analyses
Contributions to mathematical pharmacology: new receptor theory with dimeric receptor models
Authors:   , White Carla
Published: October 2021

Classical receptor theory is largely built on assumptions of monomeric receptors. In this thesis, we contribute to receptor theory by considering the now widely accepted cases of dimeric receptors. The implications of dimerisation for drug discovery and therapeutics remain unclear. Therefore, a theoretical consideration of ligand binding and signalling via receptor dimers is warranted. Here, we develop mathematical models for ligand bind-ing at dimerised and dimerising receptors. A key factor in developing these theoretical models is cooperativity across the dimer, whereby binding of a ligand to one protomer aﬀects the binding of a ligand to the other protomer. The eﬀects of cooperativity on binding dynamics are a primary point of interest.The ﬁrst models we present focus on G protein-coupled receptors, where we assume that all receptors are pre-dimerised. Ligand binding models give linear systems of diﬀer-ential equations which we use to analyse time course behaviours. At equilibrium, these models may exhibit multi-phasic log dose response curves, critically depending on co-operativity factors. When considering receptor activation, we see dose response curves that are indicative of non-standard ligand-receptor interactions, giving a quantitative and qualitative platform for analysing and interpreting data when dimers are suspected. A ligand induced model for vascular endothelial growth factor receptors is developed, whereby receptors exist constitutively as monomers and dimerise in response to ligand binding. The resulting nonlinear system of diﬀerential equations is investigated using numerical computations and perturbation methods. We see an excellent ﬁt to published data, validating the model.The utility of our models in parameter estimation is explored theoretically using structural identiﬁability analysis. This determines which parameters can be theoretically estimated from ﬁtting. This analysis is valuable but often overlooked when ﬁtting to ligand-receptor interaction models. We explore the identiﬁability of some canonical lig-and binding models, and our dimer binding models, providing a tutorial and results to contribute to the receptor theory toolbox.

A large number of field trials are being conducted in India and across the globe on the yield response and uptake of sulphur (S) in a number of crops and most results show a good yield response. However, none of the studies bring out the effect of S fertilization on S containing amino acids viz. cysteine, methionine and vitamin like Thiamine, which are essential for human life and are to be obtained only from plant foods. It is due to lack of awareness and also poor infrastructures in terms of biochemical analysis of the agricultural produce in most of the developing countries including India. Therefore, there is an urgent need to establish food quality analysis laboratories in the leading institutes of the country for initiating analysis of plant foods for S-containing organic compounds

A research study was conducted with nine dwarf Roselle germplasm of H. sabdariffa var. sabdariffa at College of Horticulture, Sri Konda Laxman Telangana State Horticultural University, Hyderabad, Telangana State, India during first week, October, 2019 to 2nd week, January, 2020. The analysis of variance for yield and its contributing characters was found to be significant for all the characters. Based on mean performance, the Roselle accession SAS-14139-1 was the best performance for yield, number of fruits per plant and plant height. Seven accessions produced green calices with red tinging, which are having good demand in the market. Good amount of genetic variability was associated with the germplasm for majority of the characters. Significant differences (p<0.05) were observed for yield characters of the accessions. This is an indication that there is a store of genetic variability that can be exploited for the improvement of Roselle in India. There was also pronounced variation in yield and other morphological parameters, suggesting the possibility of evolving higher yield variants of Roselle through proper selection. High heritability was registered with plant height, number of branches per plant and fruit yield per plant. The present study identified agronomically better germplasm for yield exploitation coupled with high heritability characters for future varietal development and use as parents in further breeding programmes in Roselle, a future reliable vegetable crop.

A study was conducted to estimate genetic variability among horticultural traits and to evaluate these hybrids for protected environmental cultivation during spring-summer season, 2019 (April-September). Twelve hybrids of tomato were evaluated under modified naturally ventilated poly-house at the Vegetable Research Farm, Department of Vegetable Science and Floriculture, Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya following Randomized Complete Block Design (RBD) with three replications, Palampur, Himachal Pradesh, India. Based on the mean performance, hybrid CLN2126×CLN1314G was found promising for yield plant-1 (4.37 kg) yield m-2 area (26.24 kg), TSS (6.53 °B), days to 50% flowering (26.66 days), days to first picking (67.33 days), number of fruits per plant (64.01), inter-nodal length (17.71 cm), number of nodes plant-1 (16.70 nodes) and plant height 316.87 cm). So, an ideal plant type producing a higher yield per plant will be the one having traits like a higher number of fruits per plant, and lesser days to first picking. It is concluded that the hybrid combination CLN2126×CLN1314G is promising for these traits. This can be included for multi-locational testing in different agro-climatic zones of Himachal Pradesh under protected environment.

The present study data on traditional knowledge and identification of uncultivated edible greens (UCGLVs) used by the people of Nalgonda district, Telangana state, India was carried out through a structured questionnaire. The data was collected from three selected villages and 90 farm women were interviewed. The compiled information shows that 22 wild edible plant species belong to 19 genera and 14 families were identified from Nalgonda district, Telangana state. Among the identified plants, most of the plants species belongs to Amaranthaceae family. People are still consuming these wild greens during their availability due to several reasons like taste, nutritious, healthy, pesticide free, free of cost and easy availability. These UCGLVs were used in traditional medicine to treat many diseases like piles, constipation, anaemia, injuries, kidney problems, back pain problems, bleeding nose and some allergies. Even though there are many health, nutritional and economical benefits with the consumption of UCGLVs, some people are not using these uncultivated green leafy vegetables presently. Reasons like increased food production, markets, availability of food, urbanization, modernization, lack of knowledge on uncultivated food, unacceptability of taste, plant infestation during rainy season and some beliefs of the people was responsible for the underutilization of uncommon green leafy vegetables. Creating awareness on uncultivated greens, their health benefits and the provision of nutritional data helps to increase dietary diversity, improves health and decrease the burden of micronutrient deficiencies.

Published: October 2021

In 1995, the State Reserve "Taimyrsky" was awarded the status of a UNESCO Biosphere Reserve. It was during this period, that the global concept of the tasks and functions of biosphere reserves as such changed. Initially, biosphere reserves were created as territories for background monitoring of undisturbed natural complexes. With the adoption of the Seville Strategy in 1995, along with this function, the task of promoting sustainable social-economic development of regions and local communities was adopted, but at the same time preserving and deepening the scientific work of the reserve - monitoring natural environment of the reserve core and adjacent areas. A zone of cooperation of the reserve was declared, including areas of compact residence and nature use of indigenous people - Dolgan and Nganasan. After the unification of all 5 federal protected areas of Taimyr in 2013 into the management of a single Unified Directorate, the implementation of the functions of the biosphere reserve, especially scientific works, for the Taimyr Reserve has become significantly more complicated. Currently, one of the main tasks is to monitor and manage the Taimyr population of wild reindeer - the basis of the traditional nature management of Taimyr people, along with domestic reindeer husbandry, fishing and fur trade. The satellite tracking program conducted since 2018 and the resumption of accounting works have made it possible to identify the unfavorable state of this population and outline measures for its protection and restoration.

The main objective of the UNESCO Man and the Biosphere (MAB) Program is to ensure a balance between the responsibility of humankind to preserve nature and its biological diversity and the need of natural resource exploitation by human being to improve the social and economic well-being of people. Biosphere reserves are recommended as representative objects for the conservation of biological diversity and, in general, ecological systems. The world network of Biosphere reserves in 2020 included 714 Biosphere reserves in 129 countries, in Russia there are 46 of them. They also act as models for achieving the goals and objectives of sustainable development of territories. The tasks include research related to climate change and the response of natural processes to these changes, implementation of space and cartographic monitoring of nature, educational activities and activities aimed at mitigating the effects of climate change. Research on the relationship between man and the biosphere in the Baikal region was carried out with an integrated environmentally oriented planning and use of lands, water and biological resources. For the Lake Baikal World Natural Heritage Site, we have carried out territorial planning and zoning, as well as determined the ecological potential of the landscapes of the Baikal natural territory.

Published: October 2021

The rigorous tobacco controls advocated by both international policy players and national government are foreseen to lowering demand in tobacco consumption, and consequently, the contraction of tobacco agriculture. This paper seeks to reveal why tobacco agriculture, albeit with the declining trend of tobacco farms, continues to persist. Theoretical guiding the investigation is based on the institutional arrangement of contract farming system, the idea that derived from New Institution Economics, and farmers’ striving to attain livelihoods. The study adopts qualitative methods, utilising purposive sampling, with 53 tobacco farmers recruited from four provinces, namely Phrae, Phetchabun, Roi-et and Nongkhai, who took part in four focus group discussions. In addition, in-depth interviews were conducted with two provincial agricultural promotion officers, three provincial excise officers and four staff members of the local office of the Thailand Tobacco Monopoly. The data was analysed using content analysis. This paper found that supportive institutional arrangements, the adaptation of communities and households creating a favourable environment and the emergence of new markets for roll-your-own cigarettes are contributing to the persistence of tobacco agriculture. In light of tobacco control, two policy measures are proposed. First, the regulations for roll-your-own cigarette industries – both smallholders and manufacturers – must be revised and instituted. Second, to encourage tobacco farmers to move away from tobacco growing, institutional support for alternative crops, such as price guarantees, inputs and technical support should be provided in the same manner that the tobacco growers currently receive.

The pineapple tarsonemid mite Steneotarsonemus ananas (Tryon), 1898 is associated with pineapple around the world, including Costa Rica. Here, we report its association with Neoregelia sp. (Bromeliaceae) for the first time. These mites damaged the plantlets considerably, affecting the esthetic quality of the product and thus causing economic losses to the local growers. This discovery prompted us to redescribe the adult females and males from the type host and locality (pineapple in Queensland, Australia) and compare it with the original description, subsequent descriptions, and material collected from the USA, Costa Rica, and Colombia on pineapple, Neoregelia, and an unidentified bromeliad. Further specimens from pineapple in Guatemala were identified as the same species and represent the first record for this country. We concur with previous observations that the original description by Tryon is not the same species in subsequent descriptions. We tentatively consider all specimens examined the same as those described as S. ananas in succeeding descriptions, i.e., Steneotarsonemus ananas Tryon sensu Beer.
The political ontology of protected area co-management: worlding and nature perceptions among stakeholders
Authors: Gambon Helen , Bottazzi Patrick
Published: October 2021

Political ontology reveals the processes of domination at play in the enactment of realities in a(post-) colonial context. In this article, we illustrate the implications of the power asymmetries inherent in conservation and co-management of protected areas involving Indigenous populations. We do so by exploring the case of Pilón Lajas in the Bolivian Amazon region, an area with double legal status as an Indigenous Territory and Biosphere Reserve. Drawing from our ethnographic fieldwork, we describe how indigenous relational ontology and the modern ontology of 'cultural diversity' are enacted by different stakeholders, and analyse critically the problems that arise for protected area management owing to the domination of a single ontology in a context where different ontologies are enacted. We finish by presenting our argument that solving such problems requires a cognitive justice approach.
Adsorption Performance of Dyes Over Zeolite for Textile Wastewater Treatment

Published: October 2021

Removal of textile dyes from wastewater have recently attracted much attention, due to the toxicity, difficult visibility, and thereby the negative consequences on the aqueous environment. Therefore, there have been diverse promising new techniques such as adsorption for dyes removal from industrial wastewater. Compared to the highly cost treatment techniques, removal of dyes using the adsorption process is relatively simple and requires less cost. Synthetic zeolite was used in this research as a high capacity nano-adsorbent for the removal of reactive dyes from coloured wastewater. The impact of main parameters: dose of adsorbent (0.0025 to 0.02 g), pollutant concentration (25 to 200 mg/L), contact time (10 to 120 minutes), degree of agitation (25 and 300 rpm), and solution pH (2 to 8) on adsorption performance of the synthesised zeolite was investigated. The optimum values of these parameters to remove dyes efficiently at 90 % removal were 0.02 g, 200 mg/L, 80 min, 300 rpm, and 6-7 respectively. Also, two models were evaluated, the Langmuir and Freundlich isotherms. Langmuir isotherm was more efficient for representing the data than the Freundlich. The results of the Langmuir isotherm gave KL
= 0.08 L/mg, qm
= 6.02 mg/g, and R
2 = 0.98, which fitted to the adsorption data of zeolite. Reactive dye adsorption by synthetic zeolite is a vital tool in identifying the fate of dye removal from industrial wastewater treatment plants.
Indebtedness Among Farmers in Haryana State, India
Authors: Jakhar Babloo , Kait Rohtas
Published: October 2021

Subject and purpose of work: The study aims to assess the nature, extent and sources of debt and the measures of the burden of debt on farmers.

Materials and methods: The study was based on primary data collected (by field survey) from a sample of 600 farmers selected from Haryana state in India. With regards to the selection of farmers/respondents, a proportionate sampling technique was employed. For the analysis of the collected data, average (or mean value) and percentage techniques were used. The data were collected in January, February and March, 2021.

Results: The study revealed that the average amount of debt per sampled farmer is 563 960 rupees. This amount of debt is very high. Institutional sources played a major role in loan disbursement to farmers. Of the total amount owed, one third of all the debt was incurred from non-institutional sources at a higher rate of interest; 67.03% was incurred for productive purposes and the remaining 32.97% of debt was incurred for non-productive purposes. Non-productive debt adds nothing to agricultural production. 67% of all farmers in the state belong to marginal and small farm-size category. Thus, at small size of land holdings, at higher rate of interest charged by non-institutional sources and non-productive loans are the main cause of farmer indebtedness.

Conclusions: Farmers have been trapped under the burden of debt and are not in a situation to pay their loans back within the prescribed period of time.
Determints of CEO Bonus Compensation

Published: October 2021

The primary purpose of this study is to explore the determinants of CEO bonus compensation: to examine CEO bonuses and to explore whether or not the independent variables are associated with CEO bonus compensation. For the purposes of this study, a sample of 2,448 CEO bonus compensations across 1,622 firms from 1997 to 2002 was used to test several hypotheses. The dependent variable in this model is the CEO bonus compensation. Bonus is the dollar value of the bonus (cash and non-cash) earned by the named executive officer during the fiscal year. Corporate diversification was divided into two categories; international diversification and industry diversification. Firm performance is measured by both Market-based, Performance (RET) and Accounting-based, Performance (ACE). The results show that the higher the degree of international diversification, and the higher accounting earnings performance, the more CEOs receive in bonuses. In addition, this study found that international diversification is associated with a greater use of bonuses and with a greater reliance on accounting-based, rather than market-based measures of firm performance. The results also demonstrated that CEOs in firms with more investment opportunities will receive higher bonuses than CEOs in firms with fewer investment opportunities and CEOs in larger firms will receive higher bonuses than CEOs in smaller firms.
Impact of Macroeconomic Variables on Exchange Rate Uncertain
Authors: Kaboro Jane , Mose Naftaly
Published: October 2021

Macroeconomic convergence is critical for member states to achieve the level of harmonization required for establishing a stable and resilient monetary union. The East African Community (EAC) member states, therefore, established set targets for macroeconomic convergence, intending to eliminate exchange rate uncertainty within the bloc and reduce the costs of the monetary union. However, recent empirical studies indicate that the rate of convergence of the member states to the set macroeconomic targets has been very slow, resulting in high exchange rate uncertainty within the region. It is against this backdrop that this research was conceptualized to examine the influence of convergence in macroeconomic variables on the exchange rate uncertainty of EAC states using secondary panel data. The study made use of standard deviation and the Levin Lin Chu (LLC) test to determine convergence and unit root respectively. The panel ordinary least squares (OLS) regression findings showed that all the explanatory variables had a negatively significant effect on exchange rate uncertainty. This implies that convergence in macroeconomic variables among the member countries slows exchange rate uncertainty. Thus, policy should be made towards controlling this negative effect resulting from macroeconomic variables as East Africa bids for monetary union.

What began as a single COVID-19 case in China in late 2019 quickly spread around the globe in the first quarter of 2020. While the impact on the world’s health systems is unknown, the economic toll remains also remains unknown as the world grapples with an unprecedented global recession. This paper estimates that COVID-19 will drag African economies into a fall of about 2,1% in GDP, with smaller economies facing contraction of up to 8%. The contraction is mainly a result of export adjustments affecting primary commodity exporters, and the attendant losses to tax revenue which reduce the capacity of government to extend the public services necessary to respond to the crisis.
Selected Impacts of Regulation (EU) 2019/631 On Value Creation in the Automative Industry
Authors: Čižinská Romana , Chládková Jana
Published: October 2021

Road transportation is responsible for a significant part of the EU’s total CO2 emissions. Therefore, the automotive sector is subject to continuously strengthening environmental regulation. Regulation (EU) 2019/631 of the European Parliament and of the Council of 17th April 2019 sets, for the period from 2020 to 2024, an EU fleet-wide target of 147 g CO2/km for the average emissions of new light commercial vehicles and an EU fleet-wide target of 95 g CO2/km for the average emissions of new passenger cars, phasing in for 95% of vehicles in 2020 with 100% compliance in 2021. If a manufacturer does not meet given CO2 standards, the excess emissions premium (penalty) is to be charged. Value creation in the automotive sector across the supply chain is necessarily undergoing a process of change. Manufacturers of passenger cars and light commercial vehicles are forced either to face a massive penalty or to invest in the development of low-emission technology and in the change of the production portfolio towards zero- and low-emission vehicles with lower profit margins and a relatively unformed customer base. The aim of this paper is to identify how the excess emissions premium affects the value creation in the automotive industry. Our methodology utilizes the income-based valuation approach. First, we conduct an analysis of the key financial value drivers of automotive companies in the period from 2016 to 2019. Subsequently, we make a prognosis of value drivers for the future period affected by the above-mentioned regulation.

Published: October 2021

Increasing the mining depth at Praid Saline and implicitly the state of stresses and strains determines an increase in the dimensions of resistance structures (pillars and ceilings). Furthermore, the seismic effect generated by the detonation of explosives contributes to the degradation of resistance structures. In order to reduce the destructive effect of drilling-blasting technology a proposal is made for the implementation of mechanized salt cutting technology which makes use of a roadheader. This article emphasizes the technical-economical implementation advantages of exploitation from the lower horizons of the New Sector, those of mechanized mining with a roadheader as opposed to the classical technology of drilling-blasting.
