ENERGY POLICY IN EUROPE AND ITS IMPACT ON ELECTRICITY SUPPLY
Authors: Malcolm W. Kennedy  , Zoran Stanić
Published: November 2022

The paper reiterates the three cornerstones of energy policy in the Western World, namely, security of supply, impact on the environment and affordability. In recent years, the EU has published vast documentation and directives on energy supply with particular emphasis on two main aspects: the identification and addressing of the malfunctioning of the EU Energy Market; and the impact of energy production and transportation on the environment. The second of these has centred on the promotion of renewable sources of energy. Having described briefly these developments to date, the paper proceeds to describe the latest attempts early in 2007 to set out an energy policy for Europe. This is designed to remove the persistent market malfunctions, improve energy efficiency and further support the development of renewable sources of energy. The paper also goes on to describe the obstacles to implementation of the energy policy at least in the short and medium terms.

Authors: Mladen Zeljko  , Miodrag Čanović
Published: November 2022

The article provides an overview of the past development, current situation and future potential of the energy sector of Montenegro. This overview is primarily based upon a project entitled Basis for the Energy Development Strategy of the Republic of Montenegro till 2025, which is the result of a joint project by the Energy Institute Hrvoje Požar, Zagreb, Croatia, and the IREET Institute, Ljubljana, Slovenia. The project began in late 2005 and ended in mid 2006. It was commissioned and implemented with the goal of providing a foundation for the development of the energy strategy for Montenegro. Since the percentage of electrical energy in the consumption of the final forms of energy is highly significant, i.e. the importance of electrical energy for the economic and overall development of Montenegro is crucial, the description of the future development of the energy sector is primarily focused upon the electrical energy sector. The coal sector is considered only to the extent that domestic coal serves as a potential energy base for the production of electrical energy.

The objective of this research is to analyze the simultaneous influence of the politicization of bureaucracy and the local head’s authority in appointing and dismissing structural officials on bureaucratic professionalism in the Gorontalo Utara government. This research engaged structural officials of all regional apparatus organizations in the environment of the Gorontalo Utara government. Findings demonstrate that politiciziation of bureaucracy had a significant influence on bureaucratic professionalism in the environment of the Gorontalo Utara government; the local head’s authority had a significant influence on bureaucratic professionalism in the environment of the Gorontalo Utara government; and politiciziation of bureaucracy and the authority f local head had a simultaneous significant influence on bureaucratic professionalism in the environment of the Gorontalo Utara government. On the other hand, the local government should confront the attempt of development acceleration and hence called for apparatuses’ professionalism; while it was clear that to manifest professionalism in state civil apparatuses, a merit system should be applied in the management of state civil apparatuses. This research was quantitative, and the research samples were 84 officials working at Gorontalo Utara government. The data analysis technique was double regression analysis. In conclusion, 1) Politiciziation of bureaucracy had a significant positive influence on bureaucratic professionalism in the environment of the Gorontalo Utara government at a coefficient of determination of 66.7%, 2) The local head’s authority had a significant positive influence on bureaucratic professionalism in the environment of the Gorontalo Utara government at a coefficient of determination of 53.9%, and 3) Politiciziation of bureaucracy and the authority of local head had a simultaneous significant positive influence on bureaucratic professionalism in the environment of the Gorontalo Utara government at a coefficient of determination of 71.5%, whereas the rest, which was 28.5%, was influenced by other factors not included in this research model.
IMPACT OF ENTREPRENEURSHIP ON EMPLOYMENT: AN ECONOMETRIC INVESTIGATION FOR TURKEY
Authors: KARAGÖZ Kadir
Published: November 2022

As is the case in the past, one of the main problems faced by economic administrators and political decision makers is increasing employment and struggling with unemployment. Turkey is a country that has had to deal with the high unemployment rates seen in almost every period since 1960’s. Especially after the 1980s, unemployment which started to increase due to globalization and technological progress reached high levels in the 1990s in terms of global measures. Besides financial and monetary policies, there are various social tools that governments can use for this purpose. Subsidies for the private sector, assistance to self-employed people, investment incentives and facilities can be regarded in this framework. It can, therefore, be expected that these policies to support entrepreneurial activities will contribute positively, both indirectly and indirectly, through employment and growth. In this study, reflections of the increase in entrepreneurship onto employment and unemployment are empirically investigated for the case of Turkey. According to the empirical findings obtained from the analysis carried out using modern time series analysis tools, while the increase in entrepreneurial activities in Turkey has a positive effect on employment in the long run, it does not have the expected effect on unemployment. This seemingly contradictory result can be explained partly by the weakness of entrepreneurial skills and partly by analyses of unsuccessful and inadequate investment.
The cultural biography, itinerary and intersections of a second-hand artefact – The case of the Knysna Half Marathon Family Champion Tankard
Authors: Snyders Hendrik
Published: November 2022

Second-hand cultural objects not only possess a very definite biography but also have a multi-layered history. The nature of this history and the cultural artefact’s evolving identity is determined, firstly, by its journey from first into second exchange and beyond, and, secondly, by the institutions, including second-hand or charity shops, individuals or groups who came to own it. Artefacts as well as places where they are exchanged, such as second-hand shops, can each provide a valuable lens to investigate the nature, social function, locational politics and exchange journey of these places and artefacts as a marker of memory. This is amply demonstrated by research into an obscure second-hand artefact, namely a beer tankard inscribed ‘Knysna Half Marathon Family Champ’, acquired from a charity shop. The object was initially appropriated by a South African family as a sports trophy to reward the best-performing athlete within their circle in the Knysna Half Marathon. Through their actions, the family inadvertently tied together the different geographic localities associated with the artefact (Knysna, South Africa and Sheffield, United Kingdom) to the Le Roux/Rous family in a manner not originally foreseen. The trophy was continuously and ritually awarded for 14 years before its mysterious disappearance. Following a long search, the researcher unravelled the mystery of its origins and use. Finally, the trophy was reunited with its original owners. Within this context, the tankard served as a record of one family’s engagement with a form of purposive leisure and their relations of love, intimacy and caring. Therefore, this article seeks to map the Knysna tankard’s cultural biography, itinerary and intersection with several diverse issues such as location, charity shopping or second exchange, sports, and family.

Published: November 2022

Background/Objectives: To assess the effectiveness and safeness of Lactobacillus reuteri and additionally three other probiotics to conventional triple therapy against the Heliobacter pylori.Materials and Methods: We randomly selected 115 H. pylori positive dyspeptic patients, to be treated for 14 days with conventional triple therapy, without and with probiotics. Our first group of 62 patients received conventional triple therapy, while the second group of 53 patients were treated with Lactobacillus reuteri, and Lactobacillus casei, Lactobacillus acidophilus, Bifidobacterium lactis, all encapsulated in PharmaS Helicobalans capsules alongside the triple conventional therapy. One month after completion of treatment, Helicobacter pylori presence was evaluated. If the Helicobacter pylori test would turn out negative, it would prove the success of the eradication.Results: 38 patients of the first group (61,3%) were treated successfully. In the second group, where probiotics were added, the success of eradication was observed in 37 of them (69.8%).Despite the fact that eradication was higher in the second group, the difference between the two sides in terms of statistics was non-significant (p=0.199). As for the side effects of the ordered treatment, 27 patients of the first group (43.5%) had complaints, while the secondary group had 17(32%). Again, there was seen no difference statistically important between two sides.Conclusion: Including probiotics additionally to conventional Helicobacter pylori treatment may decrease the side effects of the therapy, and increase the Helicobacter pylori eradication success. Randomized prospective work on a larger scale is needed.

Authors: Kurniawati Bastari Dwi , Wahyuni Tatik Dwi , Wicaksana Anggi Lukman
Published: November 2022

BACKGROUND: Fatigue is one of the most common problems experienced by chronic kidney disease (CKD) patients undergoing hemodialysis. The application of intradialytic exercises can be the best solutions to overcome fatigue related to CKD.
CASE PRESENTATION: A 50-year-old male patient with CKD, who complained of severe fatigue, was selected in case study. The FACIT Fatigue Scale questionnaire and clinical indicators were measured before and after intervention. The intradialytic exercise was administered at 3rd hour of hemodialysis for 4 sessions in 2 weeks. Each session required 30 minutes, containing warming up, main exercise and cooling down. After two weeks intervention, there was an improvement of fatigue score (16 to 29) and reduction of weakness, tiredness, washout feeling, sleepy, and tiredness on eating. Moreover, the clinical indicators showed positive improvement after the intervention.
CONCLUSION: Thus, intradialytic exercise is practically promising to minimize fatigue related to CKD among patients undergoing hemodialysis. Hemodialysis nurses or other health care providers could utilize this evidence as a program to reduce the fatigue related to CKD.

BACKGROUND: Iron-deficiency anemia (IDA) is caused by inadequate intake of iron or impaired erythrocyte formation due to chronic blood loss. AIM: This study aimed to obtain data on the prevalence of iron deficiency and IDA in the pandemic COVID-19 era and to investigate the relationship of infant nutritional status, maternal education, maternal occupation, maternal parity, and family income with the prevalence of iron deficiency and IDA in infants 9–12 months at the Cempaka Banjarbaru Community Health Center. METHODS: A cross-sectional analytic descriptive approach was used with a consecutive sampling technique to conduct this study. The sample consisted of 50 infants between 9 and 12 months old that had completed blood count and peripheral blood smear at measles immunization in May–September 2020 at the Cempaka Banjarbaru Community Health Center. RESULTS: The results showed that the prevalence of iron deficiency, IDA, and hemolytic anemia was 16%, 28%, and 22%, respectively. Meanwhile, the data analysis was conducted using Chi-square and Fisher’s exact test. The results showed a significant relationship between family income factors and the prevalence of iron deficiency and IDA (p = 0.023). CONCLUSION: Infants at the age of 9–12 months need to have a complete blood count examination to detect an earlier iron deficiency and IDA.
Scientific abstracts: Texts, contexts, and subtexts
Authors: Lang Thomas A.
Published: November 2022

In their 4000-year history, abstracts have taken several forms and represented a variety of documents. The scientific journal emerged in the 1600s and gave rise to what would become the modern scientific abstract. Here, I describe the contexts in which abstracts evolved, address the subtexts of opinions about their purpose, and review the texts of 12 kinds of abstracts. For most readers, articles do not exist beyond abstracts. However, the quality of abstracts is often poor. Inaccuracies are common, serious, widespread, and long-standing. Abstracts should inform only the choice of what to read and never what to do.
Epidemic dynamics on social interaction networks
Authors: Jelassi Mariem , Oshinubi Kayode , Rachdi Mustapha , Demongeot Jacques
Published: November 2022

The present paper aims to apply the mathematical ideas of the contagion networks in a discrete dynamic context to the modeling of two current pandemics, i.e., COVID-19 and obesity, that are identified as major risks by the World Health Organization. After providing a reminder of the main tools necessary to model epidemic propagation in a Boolean framework (Hopfield-type propagation equation, notion of centrality, existence of stationary states), we present two applications derived from the observation of real data and involving mathematical models for their interpretation. After a discussion of the obtained results of model simulations, multidisciplinary work perspectives (both on mathematical and biomedical sides) are proposed in order to increase the efficiency of the models currently used and improve both the comprehension of the contagion mechanism and the prediction of the dynamic behaviors of the pandemics' present and future states.
Artificial intelligence techniques for financial distress prediction
Authors: Zhong Junhao , Wang Zhenzhen
Published: November 2022

Artificial intelligence (AI) models can effectively identify the financial risks existing in Chinese manufacturing enterprises. We use the financial ratios of 1668 Chinese A-share listed manufacturing enterprises from 2016 to 2021 for our empirical analysis. An AI model is used to obtain the financial distress prediction value for the listed manufacturing enterprises. Our results show that the random forest model has high accuracy in terms of the empirical prediction of the financial distress of Chinese manufacturing enterprises, which reflects the effectiveness of the AI model in predicting the financial distress of the listed manufacturing enterprises. Profitability has the highest degree of importance for predicting financial distress in manufacturing firms, especially the return on equity. The results in this paper have good policy implications for how to use the AI model to improve the early warning and monitoring system of financial risks and enhance the ability of financial risk prevention and control.
On the significance of membrane unfolding in mechanosensitive cell spreading: Its individual and synergistic effects
Authors: Stolarska Magdalena A. , Rammohan Aravind R.
Published: November 2022

Mechanosensitivity of cell spread area to substrate stiffness has been established both through experiments and different types of mathematical models of varying complexity including both the mechanics and biochemical reactions in the cell. What has not been addressed in previous mathematical models is the role of cell membrane dynamics on cell spreading, and an investigation of this issue is the goal of this work. We start with a simple mechanical model of cell spreading on a deformable substrate and progressively layer mechanisms to account for the traction dependent growth of focal adhesions, focal adhesion induced actin polymerization, membrane unfolding/exocytosis and contractility. This layering approach is intended to progressively help in understanding the role each mechanism plays in reproducing experimentally observed cell spread areas. To model membrane unfolding we introduce a novel approach based on defining an active rate of membrane deformation that is dependent on membrane tension. Our modeling approach allows us to show that tension-dependent membrane unfolding plays a critical role in achieving the large cell spread areas experimentally observed on stiff substrates. We also demonstrate that coupling between membrane unfolding and focal adhesion induced polymerization works synergistically to further enhance cell spread area sensitivity to substrate stiffness. This enhancement has to do with the fact that the peripheral velocity of spreading cells is associated with contributions from the different mechanisms by either enhancing the polymerization velocity at the leading edge or slowing down of the retrograde flow of actin within the cell. The temporal evolution of this balance in the model corresponds to the three-phase behavior observed experimentally during spreading. In the initial phase membrane unfolding is found to be particularly important.

Published: November 2022

Anti-vascular endothelial growth factor (Anti-VEGF) therapy has become a standard way for choroidal neovascularization (CNV) and cystoid macular edema (CME) treatment. However, anti-VEGF injection is a long-term therapy with expensive cost and may be not effective for some patients. Therefore, predicting the effectiveness of anti-VEGF injection before the therapy is necessary. In this study, a new optical coherence tomography (OCT) images based self-supervised learning (OCT-SSL) model for predicting the effectiveness of anti-VEGF injection is developed. In OCT-SSL, we pre-train a deep encoder-decoder network through self-supervised learning to learn the general features using a public OCT image dataset. Then, model fine-tuning is performed on our own OCT dataset to learn the discriminative features to predict the effectiveness of anti-VEGF. Finally, classifier trained by the features from fine-tuned encoder as a feature extractor is built to predict the response. Experimental results on our private OCT dataset demonstrated that the proposed OCT-SSL can achieve an average accuracy, area under the curve (AUC), sensitivity and specificity of 0.93, 0.98, 0.94 and 0.91, respectively. Meanwhile, it is found that not only the lesion region but also the normal region in OCT image is related to the effectiveness of anti-VEGF.
Pandemia de COVID-19, Setting Terapêutico On-Line e Fenômenos Transferenciais

Published: November 2022

Este artigo propõe uma reflexão a partir da influência da pandemia de COVID-19 no setting terapêutico psicanalítico e levanta considerações sobre seus desdobramentos na manifestação dos fenômenos transferenciais, no que tange o manejo da relação analítica on-line. Baseia-se nos resultados de uma investigação clínico-qualitativa, realizada por meio de entrevistas com 16 participantes, dentre eles analistas e psicoterapeutas de abordagem psicanalítica. Tomando-se a técnica de análise de conteúdo como modo de interpretação dos conteúdos obtidos, percebeu-se que apesar dos fenômenos transferenciais serem constitutivos do tratamento psicanalítico, apresentaram particularidades na sua manifestação e manejo no setting terapêutico psicanalítico on-line. Diferentes foram as reações dos participantes (analistas/ psicoterapeutas) ao início da pandemia e o modo como lidaram com o período de suspensão e transição dos atendimentos presenciais para o setting on-line. O atendimento psicanalítico mostrou-se passível de ser realizado no setting on-line, mas não sem dificuldades, sobretudo considerando a gravidade do contexto e a situação de incerteza/ urgência social - que em alguns momentos se revelou como excesso e adentrou a situação analisante. Com isso foi feita também uma apreciação sobre as reações contratransferenciais, os desafios de seu manejo e as estratégias para que seu aparecimento fosse posto a serviço do processo analítico.
The Social Psychology of Terrorism
Authors: Kervalishvili Irakli
Published: November 2022

Social psychology's focus on person-situation interactions has implications for who becomes a terrorist; for example, Moghaddam posits a “staircase model” of terrorism in which terrorism is viewed as sequential progress from lower floors to higher floors that occurs on a progressively narrowing staircase. Each floor is characterized by unique psychological processes and progressive restrictions on response options, such that “destruction of others, or oneself, or both” becomes the only option. Regarding what motivates terrorism, from a psychological perspective there is little evidence that terrorists have abnormally high levels of mental illness or psychopathy. They are rational actors with purpose, intent, high levels of commitment, and deeply held convictions. Cultivated perceived threats to group identity and values (social, cultural, religious, political, etc.) are at the core of motivations for terrorism. A similar dynamic operates in responses to terrorism.

By the end of the 20th century, significant differentiation occurred in international media. These differentiations left their place in the unipolar system as the bipolar system, which had dominated the world for more than 40 years, lost its currency. However, the acceleration in international relations has led to competition in trade, military, and economy. This study tried to discuss the fail-safe movie about the Cold War period ideologically. This study aims to examine how the social and political events experienced during the Cold War period took place in the cinema and determine how the dominant ideology in this context affects the language of cinema. In the study, the film will be evaluated from a political and ideological point of view. The chapter determines which social positions and ideological reflections they reproduce by analyzing them within the framework of the stated questions and associating them with the political period they are in.
Combating Terrorism Based on the Principles of International Law
Authors: Gonitashvili Valeria
Published: November 2022

There is a growing body of international law that is directly relevant to the fight against terrorism. International law provides the framework within which national counterterrorism activities take place and which allows states to cooperate with each other effectively in preventing and combating terrorism. This framework includes instruments addressing specific aspects of counterterrorism alongside other international instruments designed for international cooperation in criminal law, the protection of human rights or refugees, or the establishment of the laws of war, which provide the broader context within which counterterrorism activities take place. International law specifically addressing terrorism exists within the general framework of international law including international criminal law, international humanitarian law, international human rights law, and refugee law.

Modern science and technology development enables humans to control devices using their brains. brain computer interface (BCI) system using EEG (Electroencephalogram) is a non-invasive method that uses brain signals to control robots. Brain control robots can assist people with disabilities to improve their livelihood. In our proposed work to control wheelchair movement for rehabilitation using EEG, electrodes are first placed on the subject's scalp to acquire brain signal activity. After that, the signals got filtered using fast fourier transformation (FFT) method, and then features got extracted using power spectral density (PSD). Random forest is used for the classification of wheelchair movement. For this purpose, a publicly available dataset from Kaggle is used, and an average accuracy of 96.79 is achieved. The proposed architecture has outperformed all the existing ones in its concerned domain; thus, it is suitable, cost-effective, and flexible for the users, which also helps maintain user privacy.
Narrow Gap Welding Principle
Authors: Vu Duong
Published: November 2022

The effectiveness of the welding process depends on some attributes, such as costs, the production time, and the quality of welding joints. This matter is more vital when dealing with the thick plates of steel for special structures in industry. To provide the quality when joining thick plates, especially with narrow gap and small chamfer angle, it is necessary to design the progressive process focusing on the main parameters, including the arc power, the translational velocity, and the rotational velocity of the tip. To evaluate the stability and the reliability of this technique, it must also perform the microstructure analysis in different zones of welding joint. In this chapter, previous publications related to this topic were gathered and analyzed. Particularly, several findings in recent studies for improving this progressive technology in the manufacturing area were discussed in detail.

Authors: Semivolos Alena , Anshari Muhammad
Published: November 2022

Artificial intelligence (AI) has become more widely used in many organizations, including logistics, such as driver assistance, parcel sorters, and inventory planners. In the times of COVID-19, the delivery drivers have become busier as more parcels are ordered, which affects their health. Due to poor management and outdated technology, the drivers cannot complete their tasks on time. However, if these organisations were to implement AI, the AI assistance would help with parcel sorting and save time on delivery packages. With the implementation of AI, the delivery time and route will also be predicted, easing the work of drivers. The customer and workers might positively accept the introduction of robotics. However, there might be some opposition from people who think that robots will take their jobs. The study used the case of logistic companies in South Korea. The study recommended that the deployment of AI could improve their performance and save the lives of drivers.

Published: November 2022

Social networking sites like Facebook, Twitter, and LinkedIn have become incredibly popular today as they have billions of registered users who share millions of units of data with each other. Yet, only a miniscule part of it is recognized as leading to some form of organizational knowledge sharing and exchange, which is a critical component of every organization's success. Employees in organizations explore social media applications to disseminate their tacit knowledge. The present study is an attempt to investigate the role of social media networks in professional knowledge sharing and building the bridging social capital of employees. Data were collected from employees working in manufacturing units in India through an empirical research design. The study's major findings revealed that social media usage enhances employees' proficiency at work by enabling knowledge sharing. On the other hand, the data uncovered an important finding that social networking sites might not build employees' bridging social capital.

Published: November 2022

Researchers and practitioners use tweets and comments on social media for emotion artificial intelligence because social media users tweet or post voluntarily. These researchers and practitioners assume tweets tweeted at different time are homogenous. This study constructed sentiment proxies from StockTwits tweets posted during NYSE non-trading hours and during NYSE trading hours. This study examined whether they predict daily S&P500 Futures, Emini Dow Futures, and Emini NASDAQ100 Futures returns using an ordinary least squares regression with Newey-West standard errors. This study found: (1) Collective sentiment at different hours of tweeting exerts a different level of influence on futures returns. (2) Positive sentiment and negative sentiment have a different influence on futures returns. (3) Returns predictability differ across the three futures contracts. Investors, businesses, and companies providing social media sentiment proxies should consider the time the tweets were tweeted and positive/negative sentiment in using social media tweets for insights.

This study is to examine knowledge sharing barriers, including individual, organizational, and technology barriers in the non-profit context. A quantitative analyze was utilized through descriptive statistical technique with data collected from the NPOs in Thailand. The sample organizations were 213 NPOs that currently are operating in diverse sectors. The investigation re-examined KS barriers identified in the literature of KM and to reflect the perspectives beyond for-profit sector. A triad of KS barriers were evaluated, but most barriers did not neatly conform to the sampled organizations in Thailand. The study illustrates an empirical insight into KM strategy for non-profit sectors in the context of developing countries, which needs more attention from the scholars.
Teaching and Learning in the Age of Climate Change
Authors: Gruber Sibylle
Published: November 2022

The chapter foregrounds the important role of teaching and learning in the age of climate change. The author shows that education for sustainable development needs to promote communication practices that not only emphasize transition and betweenness, but that transcend current definitions of disciplines to create sustainable solutions to existing problems. Such writing and communication practices are necessary to contribute to 21st century solutions to such monumental issues as increased migration due to conflict, persecution, and natural disasters; food insecurity across the globe; the erasure of economic, social, cultural, gender, civil, and political rights; and pandemics that know no borders. The chapter concludes by emphasizing the importance of encouraging students to practice transdisciplinary writing and communication skills to ensure that they can participate successfully in a world where disciplinary boundaries often hinder new and innovative approaches to finding solutions to the pressing issues raised by the current climate emergency.

Published: November 2022

User opinions are crucial in the development of mobile health (mHealth) applications (apps). This study aimed to investigate and qualitatively assess consumer attitudes toward mHealth apps and the main aspects of their design. The methodology was divided into four steps: (1) data collection, (2) preprocessing, (3) sentiment analysis by valence-aware dictionary and sentiment reasoner (VADER), and (4) thematic analysis by the latent Dirichlet allocation (LDA) algorithm. These steps were implemented in 836 reviews of eight mHealth apps on app stores in Jordan. The current study offers healthcare stakeholders insight into the positive and negative aspects of mHealth apps by identifying user-preferred features and recommending improvements. The findings indicate several aspects of design that mHealth app developers may use to improve overall efficacy, including user experience, client services, usability, and adherence.

Published: November 2022

O objetivo deste trabalho é apresentar uma sequência didática significativa para o ensino de logaritmos aliada ao uso do GeoGebra 4.2, favorecendo a formação da ideia geométrica de logaritmo. Os logaritmos tiveram seu apogeu quando revelou-se um método que permitisse efetuar multiplicações, divisões, potenciações e extrações de raízes com certa presteza, mas hoje, com o uso das calculadoras, eles perderam esta utilidade. O desenvolvimento da matemática e da ciência, de modo geral, têm nos revelado a existência de relações estreitas entre os diversos fenômenos químicos, físicos, biológicos, econômicos e os logaritmos.

Fe(Ni, Si) solid solutions were elaborated by high energy mechanical alloying from elemental Fe, Ni and Si powdersfor a milling time of 72 h. From X-ray diffraction (XRD) analysis, it has been shown that the Fe(Ni, Si) samples present a single phase in the whole range of Si content and exhibit a solid solution of disordered bcc α-Fe. The lattice parameter a (Å) of the new structures and the mean crystallitessize  (nm) were found to decrease with increasing Si contents. In contrast, the microstrain behaviour presents two different stages as the Si contents are increased. Scanning Electron Microscopy (SEM) images confirmed the behaviour of the mean crystallites size, where it can be seen that the addition of Si promotes the reduction of the size of powder particles. The saturation magnetization Ms was found to decrease by a factor of almost 1.4 and the coercively was found to increase by a factor of almost 2.4, when the Si content was increased from x= 0 % to x= 20 %. The Mössbauer spectroscopy confirmed the local in site crystal locations of Si and Ni as they diffuse into the matrix of the bcc α-Fe structure to form a solid solution.
A fluorometric assay to estimate pea leaf weevil (Coleoptera: Curculionidae) larval feeding damage using leghaemoglobin in root nodules of faba bean (Fabaceae)

The pea leaf weevil, Sitona lineatus Linnaeus (Coleoptera: Curculionidae), is an invasive pest of field pea, Pisum sativum Linnaeus, and faba bean, Vicia faba Linnaeus (Fabaceae). Larvae feed on leguminous root nodules and associated Rhizobium leguminosarum Frank (Rhizobiacea) nitrogen-fixing bacteria. Larval feeding causes economic damage, but the current method to assess nodule damage is laborious. Leghaemoglobin, the oxygen-carrying molecule in root nodules, is degraded as larvae feed. Measurement of leghaemoglobin could be an alternative method to estimate larval damage. Here, we developed a fluorometric assay to measure the variation in haem fluorescence, which relates to leghaemoglobin content, from nodulated roots. Roots were collected from caged faba bean plants with or without weevil infestation. Faba bean yield and haem fluorescence were inversely correlated with the percent damaged nodules. A plant growth score was positively correlated with haem fluorescence. This method can be used to assess nodule damage in pulse crops from pea leaf weevil and potentially from other biotic stresses, and it may have wider application to studies of nitrogen fixation.
