Changes and Problems of Agricultural Development in Iran
No full textThere has been a big debate on the evolution of agricultural development (AD), the challenges and problems hindering AD in Iran since last decade. This study was implemented in the province of Esfahan and a number of 130 out of 212 agricultural experts from 13 different townships were selected as the target group. Totally 70 experts returned the completed questionnaires. The findings of the study revealed that most of the AD changes have been positive but in a very slow rate. Respondents unanimously claimed that the sustainability in agriculture and maintenance of agricultural lands are the most deteriorating issues during last ten years. With regard to AD problems, they stressed the lack of adequate fund allocated to the Ministry of Agriculture (MAJ) and lack of its power to control beneficiary dealers within the sector, unfair political influence, lack of international contacts and also untrustworthiness of agriculture for private investors as the most problematic obstacles for AD in Iran. They perceived that MAJ has not sufficiently addressed the problems so far, although, there are some promising movements. Experts believed that MAJ is not able to solve the majority of problems alone due to their extrinsic nature
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

The wave energy flux of high frequency diffracting beams in complex geometrical optics
No full textWe consider the construction of asymptotic solutions of Maxwell's equations for a diffracting wave beam in the high frequency limit and address the description of the wave energy flux transported by the beam. With this aim, the complex eikonal method is applied. That is a generalization of the standard geometrical optics method in which the phase function is assumed to be complex valued, with the non-negative imaginary part accounting for the finite width of the beam cross section. In this framework, we propose an argument which simplifies significantly the analysis of the transport equation for the wave field amplitude and allows us to derive the wave energy flux. The theoretical analysis is illustrated numerically for the case of electron cyclotron beams in tokamak plasmas by using the GRAY code [D. Farina, Fusion Sci. Technol. 52, 154 (2007)], which is based upon the complex eikonal theory. The results are compared to those of the paraxial beam tracing code TORBEAM [E. Poli et al., Comput. Phys. Commun. 136, 90 (2001)], which provides an independent calculation of the energy flow
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Analyses of fuels, ash composition and ash melting temperatures for poultry litter with 8% aluminosilicate addition.
No full textENG:The collection contains research results produced as part of the project entitled 'Influence of aluminosilicate additives on the high-temperature corrosion process and ash characteristics of animal biomass', funded by the National Science Centre.Animal biomass is gaining popularity as an economically viable source of renewable energy. However, due to its specific composition and properties, this biomass can pose problems during thermal conversion. The aim of the project is to investigate the influence of aluminosilicate additives on the corrosion potential and properties of animal biomass ash. The project focuses on problems such as slagging propensity, high-temperature corrosion, ash grain distribution and metal content and leachability. Two types of biomass with the greatest potential are being investigated: poultry litter and from cattle dung.In the package named ‘Ash_Fuel_Analysis,’ the results of fuel and ash analyses were included for two different samples of poultry litter. The analysis results are presented in the publication: Maj, I.; Niesporek, K.; Matus, K.; Miccio, F.; Mazzocchi, M.; Łój, P. The Impact of Aluminosilicate Additives upon the Chlorine Distribution and Melting Behavior of Poultry Litter Ash. Energies 2024, 17, 1854. https://doi.org/10.3390/en17081854.. This publication also includes the results of the SEM analysis included in the dataset: Niesporek, Kamil; Matus, Krzysztof; Maj, Izabella, 2024, "Analiza SEM wpływu dodatków glinokrzemianowych na charakterystykę popiołu z biomasy pochodzenia zwierzęcego", https://doi.org/10.18150/9NS2VJ, RepOD, V1. The poultry litter samples, after pre-drying and grinding in a laboratory grinder, were combusted with an 8% fuel additive in ceramic crucibles. Aluminosilicates in the form of halloysite, bentonite, and kaolin were used as additives. The process took place at a constant temperature zone of 550°C, resulting in chemically stable ash with minimal unburned carbon.The dataset contains an XLSX file with the analysis results conducted in accredited laboratories and README text file with essential information about the provided filesPOL:Zbiór zawiera wyniki badań wytworzone w ramach projektu pt. "Wpływ dodatków glinokrzemianowych na proces korozji wysokotemperaturowej i charakterystykę popiołu z biomasy pochodzenia zwierzęcego" finansowanego przez Narodowe Centrum Nauki.Biomasa pochodzenia zwierzęcego zyskuje popularność jako opłacalne ekonomicznie źródło energii odnawialnej. Jednak ze względu na specyficzny skład i własności biomasa ta może nastręczać problemów podczas konwersji termicznej. Celem projektu jest zbadanie wpływu dodatków glinokrzemianowych na potencjał korozyjny i własności popiołu z biomasy pochodzenia zwierzęcego. Projekt skupia się na problemach takich jak skłonność do żużlowania, korozja wysokotemperaturowa, rozkład ziarnowy popiołu oraz zawartość i wymywalność metali. Badane są dwa rodzaje biomasy o największym potencjale: odpady z produkcji drobiu (poultry litter) oraz z hodowli bydła (cattle dung).W paczce o nazwie "Ash_Fuel_Analysis" zawarto wyniki analiz paliwa i popiołu dla dwóch różnych próbek ściółki drobiowej.
