Information on the elemental constituents of atmospheric aerosols is of basic importance in studying atmospheric processes for a detailed understanding of the physics and chemistry of the atmosphere. Environmental pollution and its impact can be tested in the same way, too. In the present review we survey the main research fields in aerosol analytics that can be investigated with the application of the PIXE method. The nature of emission sources, emission inventories, aerosol transport and its tracing, arctic aerosols and climatic influences are mentioned along with methodological features of the present-day PIXE technique and its combined applications with other tools of instrumental analytics.

Heterocyclic Derivatives

: Over the last decades, several heterocyclic derivatives compounds have been synthesized or extracted from natural resources and have been tested for their pharmaceutical activities. Xanthene is one of these heterocyclic derivatives. These compounds consist of an oxygen-containing central heterocyclic structure with two more cyclic structures fused to the central cyclic compound. It has been shown that xanthane derivatives are bioactive compounds with diverse activities such as anti-bacterial, anti-fungal, anti-cancer, and anti-inflammatory as well as therapeutic effects on diabetes and Alzheimer. The anti-cancer activity of such compounds has been one of the main research fields in pharmaceutical chemistry. Due to this diverse biological activity, xanthene core derivatives are still an attractive research field for both academia and industry. This review addresses the current finding on the biological activities of xanthene derivatives and discussed in detail some aspects of their structure-activity relationship (SAR).

Purpose The purpose of this paper is to provide an overview of the links between climate finance and tourism adaptation development. Besides increasing adaptation and mitigation efforts to limit greenhouse gas emissions, climate change remains a major challenge in the twenty-first century and beyond especially for tourism which is highly climate sensitive. Hence, it is necessary for tourism to adapt to survive. The aim of the study is to provide a systematic overview of the topic to offer a foundation for better understanding different ways of integrating climate finance initiatives with tourism. Design/methodology/approach The research focused on the top-ranked, peer reviewed journals of each of the two selected research fields. To address this topic, an in-depth systematic literature review in the fields of climate change finance and tourism adaptation development was conducted. Furthermore, because it is a relatively new research topic, conference proceedings were also explored. To guarantee wide coverage of the literature, a query of the following scholarly databases was considered: Elsevier, ScienceDirect and Web of Science. Findings Based on the analyses of the literature available on the topic, the paper highlights the main research trends and conclusions. It is argued that there is imbalance of knowledge on climate change finance as it relates to tourism. To date, there have been relatively few published articles on this topic in the context of tourism. Based on the findings, promising areas for future research were identified, and in particular for small island communities and recommendations for future research are outlined. Research limitations/implications The paper is limited by the scope of the literature review accessed by the researcher. The results of this review may vary according to the databases used. Originality/value Currently, there is no extensive review of articles on climate finance and tourism adaptation. This paper aims at reviewing climate finance studies published in English language to explore knowledge gaps in tourism adaptation. Sets of themes being advanced are also highlighted. Recommendations for future research are provided.

Abstract. Deformation analysis is one of the main research fields in geodesy. Deformation analysis process comprises measurement and analysis phases. Measurements can be collected using several techniques. The output of the evaluation of the measurements is mainly point positions. In the deformation analysis phase, the coordinate changes in the point positions are investigated. Several models or approaches can be employed for the analysis. One approach is based on a Helmert or similarity coordinate transformation where the displacements and the respective covariance matrix are transformed into a unique datum. Traditionally a Least Squares (LS) technique is used for the transformation procedure. Another approach that could be introduced as an alternative methodology is the Total Least Squares (TLS) that is considerably a new approach in geodetic applications. In this study, in order to determine point displacements, 3-D coordinate transformations based on the Helmert transformation model were carried out individually by the Least Squares (LS) and the Total Least Squares (TLS), respectively. The data used in this study was collected by GPS technique in a landslide area located nearby Istanbul. The results obtained from these two approaches have been compared.

Forward Kinematic

Forward kinematics is one of the main research fields in robotics, where the goal is to obtain the position of a robot’s end-effector from its joint parameters. This work presents a method for achieving this using a recursive algorithm that builds a 3D computational model from the configuration of a robotic system. The orientation of the robot’s links is determined from the joint angles using Euler Angles and rotation matrices. Kinematic links are modeled sequentially, the properties of each link are defined by its geometry, the geometry of its predecessor in the kinematic chain, and the configuration of the joint between them. This makes this method ideal for tackling serial kinematic chains. The proposed method is advantageous due to its theoretical increase in computational efficiency, ease of implementation, and simple interpretation of the geometric operations. This method is tested and validated by modeling a human-inspired robotic mobile manipulator (CHARMIE) in Python.

Systematic Methodology

Purpose In recent years, economic, environmental and social sustainability has become one of the fastest-growing research fields. The number of primary and secondary papers addressing the triple bottom line is growing significantly, and the supply chain (SC) management discipline is in the same wave. Therefore, this paper aims to propose a novel tertiary systematic methodology to explore, aggregate, categorise and analyse the findings provided by secondary studies. Design/methodology/approach A novel tertiary systematic literature review approach, including 94 secondary studies, is proposed and used to analyse sustainable SC literature. The papers have been analysed using a research protocol, including descriptive and content analysis criteria. Findings This tertiary study does not only provide an overview of the literature on the topic of sustainability in SCs but also goes further, drawing up a categorisation of main research areas and research perspectives adopted by previous researchers. The paper also presents a rank of research gaps and an updated and a prioritised agenda. Originality/value This paper provides a novel interpretation of the research topics addressed by the secondary studies and presents a new classification of the literature gaps and their evolution. Finally, a dynamic research compass for both academicians and practitioners is presented.

The Impact

The article presents a historical overview of Israeli studies at the Institute of Oriental Studies RAS in the first two decades of the 21st century. The paper demonstrates the main research fields and publications of the Department for the Study of Israel and Jewish Communities, as well as the list of its heads and research fellows. The article shows how, having successfully overcome the difficulties of the 1990s that were rather hard on Russian Academy as a whole, the staff of the Israeli Studies Department in their numerous publications, speeches at Russian and international academic forums tried to respond to the new challenges in a scholarly way. In the 2000s the number of works published on the history of relations between the USSR / Russia and Israel increased, and this trend continued in subsequent years. Access to the archives for the first time made it possible to analyze the formation and development of Soviet-Israeli relations before the break (in 1953). The department expanded the directions of its academic activity. Its topics included such directions as the study of the collective memory of Jews in modern Russia, cultural identity, cultural memory, religious and secular identity of Russian Jews, attitude towards disability and people with disabilities, study of youth communities in Israel, Russia and Europe, the impact of the US-Israeli relations on the US Jewish community. Development of basic methodology for researching the state of Jewish charity in Moscow was one of the new tasks for the fellows of the Department to solve. The novelty of the tasks also included new methodology of researching the economic and socio-political development of Israel using social networks data. The Department continued to study all aspects of the life of the State of Israel — economic, socio-political and cultural processes developing in the Israeli state, including new features in regional policy and the concept of Israeli security. At present, members of the department’s, in addition to their current activities, are implementing a number of promising projects aimed at strengthening the department’s position as the leading center of Israeli studies in the post-Soviet space.

PurposeThe purpose of this paper is to identify the main research fields concerning food label designs and build a topic overview. To this end, the literature review method was chosen.Design/methodology/approachA sample of 121 papers was identified and analyzed using bibliometric analysis. Journals, articles, authors of the sample and the term co-occurrence map, which represents the recurring themes and organizes them in clusters, were defined. To recognize the main research fields, starting from analyzing the terms that compose each cluster, the results were discussed in a focus group composed of five experts.FindingsFood labelling theories are distinctly related to eight research fields: consumer behaviour analysis, consumer willingness evaluation, consumer product evaluation, nutrition and health, daily foodstuff and meal effects, food industry and related products, impacts on market and society and child nutrition.Research limitations/implicationsSeveral stakeholders could be interested in the results of this paper. Food companies could identify the best practices in food labelling theories to improve their products and labels. Governments could understand how social policies are acknowledged by consumers and how to create new policies. Researchers could identify new issues to investigate. The results could also facilitate bibliographical referencing for those who approach this topic for the first time.Originality/valueTo the best of the authors’ knowledge, studies on food label theories explore the themes from the consumer’s perspective. The authors’ study, in contrast, focused on recognizing the research fields where food label designs are addressed.
