Karismatisk prototyp-kristologi, kvantefysikk og nevrovitenskap. En undersøkelse og vurdering av karismatisk- teologiske begrunnelser for at kristne kan gjøre undergjerninger som Jesus
Authors: Teigen Arne Helge
Published: March 2023

This article analyzes and evaluates “charismatic prototype Christology”. This is meant Christological thinking that has been developed within the charismatic movement, and which assumes that Christians potentially can do the same miraculous works as Jesus Christ. In recent times, quantum physics and neuroscience have been introduced in theological argumentation to justify this form of Christology. The article concentrates particularly on this development. Finally, an assessment is made in the light of Nicene Christology, to evaluate and provide alternative premises for theology about miracles.

Authors: Patel Snehal , Patel Narendra
Published: March 2023

Nanobiotechnology is a fast expanding scientific field with potential applications in life sciences and human health care. Silver is a precious metal that occurs naturally, most commonly as a mineral or in combination with other elements. Aqueous T. grandis plant seed extract was utilized in the current investigation as a reducing and capping agent in the biogenesis of silver nanoparticles. Nanoparticles were examined using different techniques like UV-visible spectral analysis, Fourier transform infrared spectra technique, X-ray diffraction technique, and transmission electron microscopy technique. The peak at 429 nm of the surface plasmon resonance by using UV-visible spectra, confirmed the synthesis of nanoparticles. Utilizing Fourier transforms infrared spectral analysis, the explicit functional groups that reduced silver nitrate to create silver nanoparticles in seed extract were found. X-ray diffraction analytical technique was utilized to found the crystalline nature and Face-centered cubic (FCC) configuration of green synthesized silver nanoparticles. Silver nanoparticles with sizes ranging from 32 to 62 nm are visible in images taken using transmission electron microscopy. Using disc diffusion technique, the generated silver nanoparticles showed remarkable antibacterial activity against selected organism, Escherichia coli, Bacillus subtilis, Staphylococcus aureus, and Pseudomonas aeruginosa.

Published: March 2023

In this paper, gangue Coal biochar GCC was developed to absorb heavy metals from an aqueous solution. There is currently insufficient information on the identification of the best biochar modifiers for the purpose of removing heavy metals as well as changes in physicochemical and morphological compositions after modification. For this purpose, after physical treatment GCC ware modified with 5 different offending chemical methods (GCCacidic), (GCCalkaline), (GCCoxidic), (GCCMnOx), and (GCCFeOx). Physical and chemical changes in Both modified and unmodified GCC properties were investigated by using (XRF), (FT-IR), (XRD), (SEM-EDX), and (BET) assortment. Adsorption tests of 3 heavy metals (Cu, Pb, and Cd) ions under different conditions, ion concentration, pH, Adsorbent dosage, and contact time were investigated in batch experiments. Improved post-modification GCC properties, especially (GCCalkaline) and (GCCMnOx) Significant changes in its surface area as well as functional groups (hydroxyl group, and Manganese oxide group). To will know adsorption capacity of every modified GCC, experimental data were placed in Langmuir and Freundlich’s isotherms models. The GCC process follows pseudo-second-order and pseudo-first-order kinetic curves with linear regression. GCC modified with Manganese oxide shows it has the best adsorbent for adsorption of Pb and GCC modified with alkaline is the best adsorbent for adsorption of Cd and Cu metals. For adsorption of mixed metals solution (Pb, Cd, and Cu) GCCMnOx was more suitable than other GCC and modified GCCs biochars. The results show that GCC modified with an acidic component is the worst attraction for removing heavy metals from an aqueous solution.

GRAPHICAL ABSTRACT
Making of a border island: The example of Lesvos
Authors:   University of the Aegean, Greece, Tsitsaraki Paraskevi , Petracou Electra ,   University of the Aegean, Greece
Published: March 2023

This article examines the gradual transformation of the island of Lesvos from a boundary into a border place, where migration management and border policies are pursued with the aim of controlling human mobility. Refugees have been arriving on Lesvos since 2000. This period coincided with the establishment of a common external border under the Schengen Agreement and the attempts to adopt a common asylum policy within the EU. Therefore, in this study we examine the impact of the implementation of certain border management measures on Lesvos, which have resulted in Lesvos being an example of a border that is not a line but an island (Mountz, 2014, 2020). Furthermore, the adoption of various asylum policies has led to the restriction of population mobility and the detention of people, justifying the policy and practice of abolishing asylum protection in the EU. In writing this article, we have drawn on a review of literature, reports from international organisations, legislation, relevant coverage of events in the international and local press, and participant observations.
Relações contratuais e a funcionalização do direito civil
Authors: Tepedino Gustavo José Mendes
Published: March 2023

A perspectiva funcional dos institutos jurídicos provocou a revisão da dogmática tradicional, estática e atemporal, circunscrita à estrutura das categorias jurídicas. A estrutura dos modelos negociais é definida pelos interesses que se pretende tutelar com vista às finalidades a serem alcançadas. Em tal perspectiva, o conteúdo e o papel da função social do contrato no ordenamento jurídico brasileiro justificam-se no âmbito do processo de funcionalização dos fatos jurídicos, estabelecendo-seassim a qualificação dos modelos contratuais a partir da função prático-social pretendida em determinada atividade negocial. A qualificação dos tipos contratuais a partir de sua função amplia o controle social da atividade econômica. Desse modo, a autonomia privada e a liberdade contratual recebem especial proteção do ordenamento, impondo aos contratantes, ao lado da perseguição de seus legítimos interesses patrimoniais, o dever de tutelar os interesses extracontratuais socialmenterelevantes alcançados pelo negócio jurídico. Assim, tal deve ser o norte interpretativo da chamada Lei de Liberdade Econômica. Afinal, a funcionalização da autonomia negocial encontra-se plasmada pela legalidade constitucional e a função social, por isso mesmo, reconfigura a liberdade contratual, subordinando a liberdade dos contratantes aos princípios da igualdadesubstancial e da solidariedade social.
Do positive emotions prompt people to be more authentic?
The mediation effect of gratitude and empathy dimensions on the relationship between humility state and perceived false self
Authors: Tomaszek Katarzyna
Published: March 2023

Background

Gratitude, empathy and humility have been defined as personality dispositions, as complex interpersonal emotions, and as states that prompt people to be more pro-social. However, studies on the associations between these emotions and authen-ticity are scarce. The main purpose of this study was to analyze the mediation effect of gratitude and empathy on the asso-ciation between humility and perceived false identity.

Participants and procedure

The number of participants who took part in the survey was equal to 220 university students (91% female). Students com-pleted questionnaires concerning humility (BSHS scale), gratitude (GQ scale), empathy (QCAE inventory), and perceived false self (POFS scale).

Results

The results confirmed significant correlations between gratitude, empathy and authenticity, but not with humility. Further analysis revealed that gratitude and affective and cognitive empathy explain 9% of the perceived false identity level. The findings confirmed the mediation effect of gratitude on the associations between (1) humility and false self, (2) affective empathy and false self, but not between cognitive empathy and false self. The results also indicated that humility may in-fluence authenticity indirectly via gratitude, but not via dimensions of empathy.

Conclusions

The findings confirm the significance of gratitude and cognitive empathy as dispositions that promote a feeling of being authentic. On the other hand, the relationship between affective empathy and false self was positive.
Citizenship activity in emerging adults: the role of self-esteem, social skills, and well-being
Authors: Zalewska Anna
Published: March 2023

Background

The paper considers the broad model of citizenship activity by Zalewska and Krzywosz-Rynkiewicz, including the passive (national identity and patriotism), semi-active (loyalty and voting), and active (social, political, change-oriented, and personal activity) forms of citizenship among emerging adults who already have civil rights. The study examines the profile of citizenship activity and psychological factors – personality constructs (self-esteem and social skills in intimate, social exposure, and demanding assertiveness situations) and personal experiences (emotional, social, and psychological well-being) – as correlates and predictors of civic behaviour dimensions.

Participants and procedure

A set of questionnaires (Multidimensional Self-esteem Inventory, Social Skills Inventory, Mental Health Continuum – Short Form, and Citizenship Behaviour Questionnaire-30 – general version) were completed by 140 Polish emerging adults (50% women) aged 19 to 25.

Results

Results of Student’s t-tests showed that emerging adults (like adolescents) manifested the highest level of personal activity, lower level of passive and then semi-active citizenship, even less involvement in socio-political activities, and the lowest in political activity. Particular dimensions of civic behaviours were positively but differently correlated with personality constructs and well-being – only personal activity was associated with all psychological factors. They were also differently predicted by the set of psychological variables (regression analyses), but self-esteem, so-cial exposure skills, and social well-being were particularly important predictors.

Conclusions

These results indicate that policies promoting the citizenship activity of emerging adults need to recognise, support, and strengthen these psychological variables, as they can be modified by deliberate influences and interventions that may be the subject of further research.
Development and validation of a stress response measure: the Daily Stress Response Scale (DSRS)
Authors: Debowska Agata , Horeczy Beata , Boduszek Daniel , Dolinski Dariusz , von Bastian Claudia C.
Published: March 2023

Background

To date, there is a lack of measures for capturing a broad spectrum of psychophysiological stress reactions that can be administered on a daily basis and in different contexts. A need for such a measure is especially salient in settings where stress processes can unfold momentarily and substantially fluctuate daily. Therefore, the main aim of the current study was to develop and validate the Daily Stress Response Scale (DSRS), an instrument capturing a broad spectrum of psycho-physiological stress reactions that can be administered in real time and in different contexts.

Participants and procedure

The study was conducted in the early stages of the COVID-19 pandemic in Europe. Participants were 7228 (81% female) Polish university students. The data were collected anonymously through self-completion questionnaires. The DSRS was subject to confirmatory factor analyses (CFA).

Results

The DSRS is a 30-item, easy-to-use stress response measure with excellent psychometric properties. Based on CFA results, the scale consists of two subscales, psychological and physiological stress response, which form associations with related external criteria.

Conclusions

The DSRS is a reliable and valid measure of psychological and physiological stress reactions that can be used to assess the stress response to daily stressors, including those of an acute nature, such as a crisis, trauma, or surgery.
Psychosocial work strains and well-being in the process of adapting to occupational stress: longitudinal studies of offshore rig workers
Authors: Leszczyńska Irena , Peplińska Aleksandra
Published: March 2023

Background

The work on offshore rigs is related to a number of physical and mental burdens. The subject matter of the paper refers to the assessment of the relation between the mode of adapting to occupational stress and the feeling of well-being among the employees of offshore rigs in Poland.

Participants and procedure

The research procedure is a longitudinal study and encompasses analysis of data between 1993 and 2014. 167 employees of the Polish offshore rigs were studied: all of them were male and the average age was 42. Measuring tools were used to as-sess the subjective occupational stress, psychosocial work conditions, evaluation of physical and mental well-being and styles of coping with stress.

Results

The perceived level of stress directly affects mental well-being (r = .19, p = .048): the higher the level of stress, the worse is the mental well-being (β = –.30). In a considerable part, the dependence between occupational stress and mental well-being may be clarified by the impact of the style of coping with occupational stress and the rate of stress dynamics (r = .32, p = .004). The higher the share of task-oriented coping style as compared to the emotion and avoidance-oriented style, the higher is the self-reported mental well-being. The higher the probability of affiliation with the group reporting a decrease in stress, the higher is the self-reported mental well-being. Perceiving stress has no direct or indirect impact on physical well-being (β =. 09; β = .08; β = –.11).

Conclusions

A dependence exists between the process of adapting to stress and the level of the self-reported mental well-being of the rig employees. The higher the probability of adaptation to the difficult situation at work in a way that the self-reported stress is reduced, the higher the self-reported mental well-being. Perceiving stress bears no direct or indirect impact on the physical well-being.
Emotional and experiential factors that determine civilizational diseases
Authors: Misiołek Kamila , Błażek Magdalena
Published: March 2023

Background

The effects of adverse childhood experiences may persist in adult life and manifest themselves in various areas of function-ing. The aim of the study was to identify the emotional and experiential factors that determine civilizational diseases and the methods of regulating emotions and functioning in society.

Participants and procedure

The surveyed group was composed of 141 adults. The respondents defined the existence of adverse experiences and their attachment styles in retrospective. The methods of regulating emotions were also measured, as well as the presence of civilizational diseases.

Results

The authors found a correlation between the style of attachment and the traumatic events experienced during the first 18 years of life and the existence of civilizational diseases. Adverse experiences in childhood and attachment styles proved to be predictors of specific social behaviour aimed at regulating emotions.

Conclusions

The results emphasised the importance of the bond with a parent and of traumatic childhood experiences for the future health condition and for the social and emotional functioning. The study demonstrated that persons who experienced traumatic events in their families or in the peer environment in the first 18 years of their lives reported the presence of civilizational diseases. A correlation was found between peer violence, the threat of being abandoned by a caregiver, and diagnosed civilizational diseases in respondents. The fearful-ambivalent style in the relationship with the father proved to be a predictor of reported civilizational diseases. Adverse childhood experiences are linked to regulating emotions by tak-ing perspective. The attachment style developed in the relationship with parents determined the ways of regulating nega-tive and positive emotions in contact with other people. Persons who developed an avoidant attachment style in the rela-tionships with the mother or the father less frequently seek social support when they experience negative emotions.

Published: March 2023

Background

Adhering to clinical prescriptions is known to protect against the effects of uncontrolled hypertension and of acute and chronic cardiovascular diseases, including diabetes. Contextually, positive associations between self-care behaviors and psychological constructs, such as self-efficacy, are widely acknowledged in the literature. However, still little is known about the psychological factors underlying the patient’s self-efficacy. This study aimed to investigate the psychosocial and behavioral correlates of self-efficacy related to treatment adherence in older patients with comorbid hypertension and type 2 diabetes mellitus.

Participants and procedure

Italian and Polish patients (≥ 65 years; N = 180) consecutively responded to self-report questionnaires measuring psycho-social (i.e., beliefs about medicines, perceived physician’s communication effectiveness, medication-specific social sup-port, self-efficacy) and behavioral factors (i.e., pharmacological adherence, medications refill adherence, intentional non-adherence) related to treatment adherence. Between-group comparisons and regression analyses were performed.

Results

Fisher’s least significant difference (LSD) test showed significant differences between the Italian and Polish groups in all questionnaires (p < .01) with the Italian patients reporting more satisfactory scores. Younger age (β = .08, p = .045), female gender (β = 1.03, p = .042), higher medication refills adherence (β = –.07, p = .024), lower intentional non-adherence (β = –.03, p = .009), positive beliefs about medications (β = .13, p < .001), better quality of communication with the physician (β = .09, p < .001), and stronger perceived medication-specific social support (β = .06, p = .001) were significantly associat-ed with self-efficacy related to treatment adherence.

Conclusions

Future research and interventions should leverage psychosocial and behavioral factors to address self-efficacy contributing to enhancing adherence to clinical prescriptions.

Published: March 2023

The aim of this study is to establish the ideal clinician's approach to nutritional bicytopenia in the context of adequate micronutrient supplementation. We present the case of a 27-year-old patient living with obesity, subjected for months to a very low-calorie diet and adequate supplementation with complementary vitamins and minerals, evaluated and treated for bicytopenia with irondeficiency anemia and lymphocytopenia. The use of meal replacement supplements as nutritional sources replacing food items requires medical supervision as they can have consequences on the patient's micronutrient balance. Classically, and frequently, iron-deficiency anemias have been identified as the most common condition in these restrictive nutritional regimens. However, alterations in the white cell line are more frequent than believed and may be associated with multiple nutritional deficiencies including folic acid and vitamin B12. The diagnostic approach becomes complex when the most common nutritional causes are hidden by replacement supplements. The patient achieved an increase in hemoglobin after treatment (12.3 g/dL), recovering from anemia. When approaching nutritional cytopenias, the primary takeaway should always be the thinking process. Every patient with bicytopenia must be studied particularly meticulously, and the good clinician is forced to address it and reach the most likely diagnosis within the common and the rare.

WEAR ANALYSIS OF VERTICAL COAL MILL PLATE
Authors: Bertawan Bertawan , Pratiwi Diah Kusuma
Published: March 2023

Vertical Coal Mill (VCM) is equipment for grinding and pulverizing coal into micron size. Rotary kilns then use the powders as fuel burners. The VCM has a housing section equipped with a lining plate as a wear and tear protector. The housing comprises segments with similar thicknesses and materials that are severe to wear due to gas-carrying solid particles hitting the surface. The specific material resilient to abrasion is required to extend operating services. This study aims to determine the wear properties of Hardlite and Everhard C500LE on the lining plate. Characterization of the samples, including composition, microstructure, hardness, and wear test. Microstructure observation shows that the more extensive and profound the wear marks formed, the higher the volume of exfoliated material. The test results show that the Fe-Cr-C hard-facing alloy significantly affects the hardness value of a material and its wear resistance. The hardness test results showed an average Hardlite overlay layer hardness value of 703 BHN (N/mm2), almost double that of Everhard C500LE.

The results of calculating the performance of the decision tree method that implements the discretization technique show that this method is very good at predicting air quality, as indicated in particular by the Average Accuracy value of 99.05%, Macro Precision of 78.59%, and Macro Recall of 77.46%.
CATASTROPHIC FAILURE INVESTIGATION OF THE OIL FILTER MACHINE BOLTS
Authors: Prayogo Gatot
Published: March 2023

An assessment of the fractured bolt of a cooking oil filter machine was performed. The objective of this assessment is to reveal the root cause of the failure. A series of necessary attempts were carried out for this analysis, i.e., site visit, fracture surface examination of the fractured bolt, collecting the maintenance and operation data, mechanical properties testing, chemical composition testing, and stress analysis. The fracture surface examination showed a catastrophic failure, especially at a repaired bolt. Meanwhile, according to the site visit investigation, some evident data indicated a sudden high-pressure load subjected to the filter machine. Most fractured filter bolts were repaired by welding. The design review shows that the critical operating pressure is around 14.5 bar, which is far above the reported operating pressure during the accident, which is 6 bar. This indicated that the strength of the genuine bolt is sufficient to ensure the operating pressure of the filter machine, which is normally 1 to 3.5 bar. Finally, it can be concluded that the root cause of the failure of the filter machine bolt is decreasing strength of the bolts because of improper repairment indicated by the welding process and assisted by sudden high load due to increasing pressure inside the filter vessel.

Published: March 2023

Storm water management in urbanized areas is currently a global issue. In order to verify the correct functioning of the sewer networks and their objects, it is necessary to regularly assess their hydraulic capacity. Key of assessing the capacity of single and rainwater sewer networks is the calculation of the amount of surface runoff and the selection of a suitable design rainfall model. This article deals with the issue of effective decision making in the choice of the design rainfall for the hydraulic assessment of the sewer systems. DATER (decisive analytical tool for effective rainfall) was used as a analytical tool for rain analysis. This article incorporates case study in town of Vráble.

Prístup k dodržiavaniu bezpečnosti a ochrany zdravia pri práci je v rôznych organizáciách veľmi odlišný. Pokiaľ sa zamestnávateľ rozhodne pristupovať k vytváraniu bezpečného pracovného prostredia, budú jeho náklady na prevenciu vyššie, ale prínosy v podobe nižších počtov pracovných úrazov, vyššej produktivity práce a lepšieho imidžu firmy budú o to väčšie. Naopak, v prípade, keď sa rozhodne šetriť náklady vložené do oblasti BOZP, môže očakávať len nestabilné pracovné prostredie a sankcie až v likvidačnej hodnote, najmä u malých a stredných podnikov. Vhodným prostriedkom na získanie porovnateľných hodnôt špecifických ukazovateľov je matematický model, ktorý vyjadruje závislosť medzi nákladmi na prevenciu a nákladmi na nápravu v súvislosti s rôznymi postojmi zamestnávateľov k BOZP. Ich rozhodnutia vo vzťahu k významu BOZP sú veľmi dôležité a závisia od nich dokonca životy samotných zamestnancov.

The Construction industry plays a key role for governments in both growing and mature economies. The sector creates new jobs, drives economic growth, and provides solutions to address social, climate and energy challenges. The construction industry has important linkages with other sectors, so that its impact on GDP and economic development goes well beyond the direct contribution of construction activities. Most factors, which influence and drive change in the sector, will affect the sector in the years to come. Most of the driving forces mentioned are external factors, which are changing the framework conditions. The main aim of this article is to point out the impact of important factors on the development of the construction sector in EU.

La question périurbaine
Authors: CHARMES Éric
Published: March 2023

Ce chapitre, après avoir défini et caractérisé géographiquement la périurbanisation en France, examine les mutations sociologiques et politiques des campagnes. Le chapitre s’intéresse ensuite au cas des villes moyennes, dont beaucoup sont aujourd’hui dominées par leurs couronnes périurbaines, avant de se pencher sur la situation inverse des grandes métropoles, où le périurbain est souvent vu comme un lieu de relégation.
Les villes moyennes et les inégalités territoriales

Ce chapitre se concentre sur une figure désormais bien débattue des politiques d’aménagement et de leurs relations au traitement des inégalités territoriales : les villes moyennes. À la croisée de différents mouvements sociaux, mais également de travaux académiques, le débat sur la légitimité de cette catégorie de villes à asseoir les objectifs contemporains des politiques d’aménagement, dont celui de la réduction des écarts de développement entre les territoires, anime depuis quelques années les réflexions et les actions concrètes du champ de l’action publique à finalité territoriale.
Evaluation of open- and closed-path sampling systems for the determination of emission rates of NH3 and CH4 with inverse dispersion modeling
Authors: Lemes Yolanda Maria , Häni Christoph , Kamp Jesper Nørlem , Feilberg Anders
Published: March 2023

Abstract. The gas emission rates of ammonia (NH3) and methane (CH4) from an
artificial source covering a surface area of 254 m2 were determined by
inverse dispersion modeling (IDM) from point-sampling and line-integrated
concentration measurements with closed- and open-path analyzers. Eight
controlled release experiments were conducted with different release rates
ranging from 3.8±0.21 to 17.4±0.4 mg s−1 and from 30.7±1.4 to 142.8±2.9 mg s−1 for NH3 and CH4,
respectively. The distance between the source and concentration measurement
positions ranged from 15 to 60 m. Our study consisted of more than 200
fluxes averaged over intervals of 10 or 15 min. The different releases
cover a range of different climate conditions: cold (<5 ∘C), temperate (<13 ∘C), and warm (<18 ∘C). As the average of all releases with all instrument types, the CH4 recovery rate QbLS/Q was 0.95±0.08 (n=19).
There was much more variation in the recovery of NH3, with an average
of 0.66±0.15 (n=10) for all the releases with the
line-integrated system. However, with an improved sampling line placed close to the source an average recovery rate of 0.82±0.05 (n=3) was
obtained for NH3. Under comparable conditions, the recovery rate
obtained with an open-path analyzer was 0.91±0.07 (n=3). The
effects of measurement distance, physical properties of the sampling line,
and deposition are discussed.
Convective parameters for severe weather forecasting and research in Australia
Authors: Warren Rob , Blockley Ivor , Sgarbossa Dean , Richter Harald
Published: March 2023

The Australian Bureau of Meteorology (BoM) has recently operationalized a post-processing suite called ConvParams, which computes a wide array of convective parameters using output from the BoM’s global deterministic and ensemble NWP models. Outputs from the suite include parcel parameters such as CAPE and CIN (computed for a range of different initial parcels), kinematic diagnostics such as bulk wind difference and storm-relative helicity (computed for a range of different atmospheric layers), and composite indices such as the supercell composite parameter and significant tornado parameter. In addition, the suite also identifies important features in the atmospheric profile such as capping inversions and elevated mixed layers. A unique feature of ConvParams, compared to other similar codebases (NSHARP/SHARPpy, MetPy) is its use of high-order polynomials to approximate pseudoadiabatic processes, which permits parcel calculations that are both fast and highly accurate. Significant computational advantages also come from the use of an ahead-of-time compiler (Pythran), which “transpiles” the native Python code into fast C++ code. As well as being used in operations, ConvParams is being run as part of the second-generation BoM Atmospheric Regional Reanalysis for Australia (BARRA2), a regional downscaling of the ERA5 reanalysis, and the BoM Atmospheric Regional Projections for Australia (BARPA), a regional downscaling of CMIP6 climate projections. Once complete, these simulations will provide the most comprehensive picture of historical and future convective environments in Australia to date, supporting major research in this space over the coming years. This presentation will provide an overview of the ConvParams suite and highlight its applications in both operational forecasting and future research endeavours.

Abstract. Icelandic dust can impact the radiative budget in high-latitude regions directly by affecting light absorption and scattering and indirectly by changing the surface albedo after dust deposition. This tends to produce a positive radiative forcing. However, the limited knowledge of the spectral optical properties of Icelandic dust prevents an accurate assessment of these radiative effects. Here, the spectral single scattering albedo (SSA) and the complex refractive index (m = n - ik) of Icelandic dust from five major emission hotspots were retrieved between 370–950 nm using online measurements of size distribution and spectral absorption (βabs) and scattering (βsca) coefficients of particles suspended in a large-scale atmospheric simulation chamber. The SSA(λ) estimated from the measured βabs and βsca increased from 0.90–0.94 at 370 nm to 0.94–0.96 at 950 nm in Icelandic dust from the different hotspots, which falls within the range of mineral dust from northern Africa and eastern Asian. The spectral complex refractive index was retrieved by minimizing the differences between the measured βabs and βsca and those computed using the Mie theory for spherical and internally homogeneous particles, using the size distribution data as input. The real part of the complex refractive index (n(λ)) was found to be 1.60-1.61 in the different samples and independent on wavelength. The imaginary part (k(λ)) was almost constant with wavelength and was found to be around 0.004 at 370 nm and 0.002–0.003 at 950 nm. The estimated complex refractive index was close to the initial estimates based on the mineralogical composition, also suggesting that the high magnetite content observed in Icelandic dust may contribute to its high absorption capacity in the shortwave spectrum. The k(λ) values retrieved for Icelandic dust are at the upper end of the reported range for low-latitude dust (e.g., from the Sahel). Furthermore, Icelandic dust tends to be more absorbing toward the near-infrared. In Icelandic dust, k(λ) between 660–950 nm was 2–8 times higher than most of the dust samples sourced in northern Africa and eastern Asia. This suggests that Icelandic dust may have a stronger positive direct radiative forcing on climate which has not been accounted for in climate predictions.
