The concept of justice (pravda) in Croatian
Authors: Kapetanović Amir
Published: February 2021

This paper analyses the linguistic concept of justice (pravda) in Croatian according to the methodology of the Lublin Ethnolinguistic School. Recent monolingual dictionaries of Croatian typically list only one meaning of the lexeme pravda and lexicographic definitions focus on the social aspect of the term. The paper also analyses the relationship of this lexeme with others (synonyms, antonyms) and lists phrases and sayings related to pravda. An analysis of a corpus of Croatian texts (of the last 150 years) and the results of a survey (100 respondents) point to weaknesses in lexicographic definitions of the lexeme pravda, as well as to the complexity of the concept of pravda in Croatian. According to the results of the survey, the most important characteristics of pravda are equality and acting on merit, followed by the ethical aspect (respect, morality, truth) and the psychological aspect (satisfaction/happiness, freedom, conscience).
Disease and its metaphors in contemporary Polish female poetry
Authors: Morzyńska-Wrzosek Beata
Published: February 2021

The article deals with metaphors of disease in selected contemporary Polish female poets. In focus are the portrayals of disease, its symptoms and consequences for the imperfect human body. The anthropological perspective assumed in this study, which reveals the coding of human experience in a literary work, emphasises the connections between the poetics of the work and the problem of defining individual identity. The analysis leads to the following conclusions: the poets (both in lyrical poetry and other intimist writing) usually relate to conceptual metaphors motivated by the notions of object and containment (e.g. life is a container, body is an object, body is a container); other recognizable metaphors are orientational (wpaść w wilczy dół ‘fall into the pitfall’) or grounded in the notion of fire (czuję się spalona ‘I feel consumed by flames’). By modifying classic metaphors, the poets construct new cognitive perspectives. They express the feeling of isolation from the world of the healthy and the fragility of the human body as a material “prison house”. They also make attempts to regain control over it by extending the boundaries of intimacy. By studying the esthetic and epistemological aspects of metaphors in connection with an understanding of self in a situation of irreversible loss of full physical control, of fear and of bold expansion of one’s corporality, it is possible to identify individual and cultural grounding of corporality.
Ethnolinguistics in etymological research
Authors: Jakubowicz Mariola
Published: February 2021

The article is devoted to the relationship between etymology and ethnolinguistics, with particular reference to the usefulness of ethnolinguistic research in the work of etymologists. In the last thirty years numerous Slavists have combined their interest in one of these branches with an application of their research in the other branch. The article focuses on ethnolinguistics as it is represented in Słownik stereotypów i symboli ludowych [Dictionary of Folk Stereotypes and Symbols], which explores mainly texts of folklore. It presents links binding two directions of research: (1) relations between elements of the world, from the immediate environment to the Cosmos, considered from the point of view of texts of folklore on the one hand and etymology on the other; (2) analyses of synonymous and antonymous conceptual pairs that manifest parallelism both in folklore and etymology; (3) traditional evaluation and the associated linguistic taboo.
Abundance, fatty acid composition and saturation index of neutral lipids in colorectal cancer cell lines
Authors: Munir Rimsha , Lisec Jan , Jaeger Carsten , Zaidi Nousheen
Published: February 2021

Lipid droplets, the dynamic organelles that store triglycerides (TG) and cholesterol esters (CE), are highly accumulated in colon cancer cells. This work studies the TG and CE subspecies profile in colon carcinoma cell lines, SW480 derived from primary tumor, and SW620 derived from a metastasis of the same tumor. It was previously reported that the total TG and CE content is dramatically higher in SW620 cells; however, TG and CE subspecies profile has not been investigated in detail. The work presented here confirms that the total TG and CE content is significantly higher in the SW620 cells. Moreover, the fatty acid (FA) composition of TG is significantly altered in the SW620 cells, with significant decrease in the abundance of saturated triglycerides. This resulted in a significantly decreased TG saturation index in the SW620 cells. The saturation index of CE was also significantly decreased in the SW620 cells.

Published: February 2021

Background: Multiple sclerosis (MS) is one of the most common autoimmune diseases worldwide and various autoimmune comorbidities are reported with MS. The objective of this study is to estimate the prevalence of the autoimmune diseases’ comorbidity in patients with MS.
Methods: In this cross-sectional study, we investigated a group of patients with MS in terms of age, gender, duration of MS, presence of simultaneous autoimmune diseases, such as Graves’ disease, Hashimoto’s thyroiditis, type 1 diabetes mellitus (DM), and systemic lupus erythematous (SLE).
Results: This study included 1215 patients with MS, of which 70.8% were women. The mean age of participants was 33.70 ± 27.63 years. 55 patients (4.5%) had at least one autoimmune disease. The most common comorbidity was for Hashimoto’s thyroiditis (30 patients). The frequency of simultaneous autoimmune disease was higher in women. Mean age (P = 0.01), mean duration of MS (P = 0.03), and mean age on MS diagnosis (P = 0.02) were significantly higher in simultaneous MS and other autoimmune diseases.
Conclusion: Our study revealed that the probability of autoimmune diseases co-occurrence in patients with MS could be higher in older patients, in longer duration of disease, and also in patients with higher age at time of MS diagnosis.

Published: February 2021

Background: Psychogenic non-epileptic seizures (PNES) are manifested as paroxysmal alterations in motor, sensory, autonomic, and/or cognitive and behavioral signs and symptoms, without associated ictal epileptiform discharges. A misdiagnosis of PNES as epilepsy results in a prolonged and unnecessary (antiepileptic) drug treatment and social and psychological stigma of epilepsy in these patients. This study aimed to determine the epidemiology, clinical manifestations, and associated factors of PNES in hospitalized patients in the video-electroencephalography (EEG) monitoring (VEM) service of Razi Hospital, Tabriz, Iran.
Methods: In this cross-sectional descriptive study, 55 patients with a final diagnosis of PNES were selected from the patients referred to the VEM unit of Razi Hospital for the evaluation of epilepsy. The study was performed from May 2017 to June 2019. Patient information included demographic data and medical history (drug history, comorbidities, trauma, and family history). The clinical manifestations (semiology and duration of attacks) and EEG findings, as recorded by VEM during hospitalization, were collected.
Results: 55 patients with PNES were studied with VEM, 27 (49.1%) of which were men, and 28 (50.9%) were women. The mean and standard deviation (SD) of age of the patients was 34.16 ± 12.64 years. No significant differences were observed in the semiology of PNES between men and women. Depression was the most common psychiatric comorbidity.
Conclusion: The clinical manifestations of PNES in the present study were similar to those in most previous studies from other countries. The culture and sex of the patients did not seem to be a contributing factor in PNES semiology.

Published: February 2021

Background: Few studies have reported the association of Guillain-Barre syndrome (GBS) and coronavirus disease-2019 (COVID-19) infection. In this study, we reported GBS in six patients infected with COVID-19 and reviewed all existing literature about GBS in association with COVID-19.
Methods: This study was performed in three referral centers of COVID-19 in Iran, and six patients with the diagnosis of GBS were enrolled. Patients enrolled in the study with acute progressive weakness according to the demyelinating or axonal variant of GBS, according to Uncini's criteria.
Results: Four of our patients had axonal polyneuropathy, two patients had demyelinating polyneuropathy, and one patient required mechanical ventilation. All our patients had a favorable response to treatment. In one patient, the GBS symptoms recurred four months after the first episode.
Conclusion: Limited case reports suggest a possible association between GBS and COVID-19. Such associations may be an incidental concurrence or a real cause-and-effect linkage; however, more patients with epidemiological studies are necessary to support a causal relationship.
A history of the path towards imaging of the brain: From skull radiography through cerebral angiography
Authors: Kamal Haris , J. Fine Edward , Shakibajahromi Banafsheh , Mowla Ashkan
Published: February 2021

This publication reviews the steps in the path towards obtaining a complete image of the brain. Up to the 1920s, plain X-ray films could demonstrate only calcified tumors, shifts in midline position of a calcified pineal gland due to a mass in the cranium, or foreign metallic objects within the skull. Walter Dandy reported in 1918 that he visualized cerebral ventricles by introducing air as a contrast agent through a trocar into one of the occipital lobes or the right frontal horn of the ventricular system. Dandy localized lesions that distorted or shifted the ventricles. In 1920, Dandy placed air by lumbar puncture into the spinal subarachnoid space that could visualize the brain and entire ventricles. Antonio Egas Moniz with the assistance of his neurosurgeon colleague, Almeida Lima, obtained X-ray images of cerebral arteries of dogs and decapitated human heads from corpses after injecting strontium bromide into their carotid arteries. Satisfied by these experiments, Moniz injected strontium bromide directly into carotid arteries of five patients which failed to show intracranial vessels. In the sixth patient, intracranial arteries were outlined but that patient died of cerebral thrombosis presumably due to the hyper- osmolality of that contrast agent. Finally, on June 18, 1927, Moniz injected 22% sodium iodine into a 20-year-old man and obtained clear visualization of his carotid artery and intracerebral branches after temporarily occluding the artery with a ligature.

Authors: Khamverdi1 Zahra , Najafrad Elmira , Farhadian Maryam
Published: February 2021

Objectives: Marginal and internal fit of restorations are two important clinical factors for assessing the quality and durability of computer-aided design/computer-aided manufacturing (CAD/CAM)-fabricated monolithic zirconia restorations. The purpose of this study was to evaluate the marginal and internal fit of CAD/CAM zirconia crowns with two different scanners (i3D scanner and 3Shape D700).
Materials and Methods: Twelve extracted sound human posterior teeth were prepared for full zirconia crowns. Two different extraoral scanners namely i3D scanner and 3Shape D700 were used to digitize type IV gypsum casts poured from impressions. The crowns were milled from presintered monolithic zirconia blocks by a 5-axis milling machine. The replica technique and MIP4 microscopic image analysis software were utilized to measure the marginal and internal fit by a stereomicroscope at ×40 magnification. The collected data were analyzed by paired t-test.
Results: The mean marginal gap was 203.62 μm with 3Shape D700 scanner and 241.07 μm with i3D scanner. The mean internal gap was 192.30 μm with 3Shape D700 scanner and 196.06 μm with i3D scanner. The results of paired t-test indicated that there was a statistically significant difference between the two scanners in marginal fit (P=0.04); while, there was no statistically significant difference in internal fit (P=0.761).
Conclusion: Within the limitations of this study, the results showed that type of extraoral scanner affected the marginal fit of CAD/CAM fabricated crowns; however, it did not have a significant effect on their internal fit.

Published: February 2021

Nurses need to be resilient to be able to endure their working conditions, and their moral courage can affect their resilience. This work aimed at studying the relationship between resilience and professional moral courage among nurses working in hospitals. This descriptive cross-sectional study was conducted on 375 nurses working in teaching hospitals in the city of Ardabil in Iran in 2019. Data was collected using the following questionnaires: a demographic questionnaire, Sekerka et al. Moral Courage Scale and Davidson-Connor Resilience Scale. The reliability of the Davidson-Connor Resilience Scale, and Moral Courage Scale were found to be 89% and 85% using the test-retest method. The data were analyzed by Pearson correlation coefficient, t-test, variance analysis, and linear regression using the SPSS software version 24. In participating nurses, mean scores were 6.35±0.5 for total moral courage (favorable) and 79.35±0.35 (moderate) for resilience, respectively. A positive and significant relationship was observed between resilience and professional moral courage (P<0.05, r=0.1). Given the positive and significant relationship between resilience and professional moral courage, nurses require to have the high moral courage to enhance their resilience. Determining factors affecting moral courage and resilience, as well as finding strategies and creating an appropriate moral climate can increase nurses' morally courageous behaviors and resilience.

Authors: Jereb Eva
Published: February 2021

V prihodnosti lahko pričakujemo velike spremembe na področju strukture delovnih mest. Tehnološki napredki in digitalizacija bodo zahtevali višjo stopnjo sodelovanja in bolj fleksibilno delovno okolje. Svoje bo terjala tudi avtomatizacija, ki bo prinesla ogromne spremembe, primerljive s spremembami industrijske revolucije. Poleg tega na delovna mesta prihaja generacija Y, katere pripadnike imenujemo tudi milenijci, ki se močno razlikuje od prejšnjih generacij, še posebej od generacije, ki ji pravimo babyboomerji in ki trenutno še vedno zaseda določena ključna delovna mesta. Milenijci na delo in delodajalca gledajo drugače kot prejšnje generacije in imajo tudi drugačna pričakovanja. Če se organizacije v času tako velikih sprememb managementa ne bodo prilagodile novi delovni sili in ne bodo znale uskladiti zaposlenih različnih generacij, se bodo srečale z velikim mankom zaposlenih, sploh na ključnih delovnih mestih. V prispevku je najprej podanih nekaj osnovnih značilnosti trenutno najbolj zastopanih generacij na delovnih mestih v organizacijah. To so tako imenovani babyboomerji, generacija X in milenijci. Ne bomo pa govorili o veteranih in prihajajoči generaciji Z. Nadalje so predstavljene osnove vodenja trenutno najobsežnejše generacije delovne sile, to je milenijcev. Podani so predlogi, kako ravnati z novo, mlado delovno silo in kako usklajevati predstavnike različnih generacij, da bodo le-ti zavzeti za delo.
Othello and the Ambivalences of Italian Blackface
Authors: Bassi Shaul , Scego Igiaba
Published: February 2021

Blackface is a cultural practice that appears ubiquitously in Italian history cutting across the political spectrum; it also lends itself to suprising anti-racist actions. This essay examines the use of blackface from the nineteenth to the twenty-first century by looking at its appearance in popular culture and, contextually and dialectically, at its adoption in selected performances of Othello, a play that holds special meaning in Italy because of its famous operatic adaptations. Africa and blackness were often represented in Italian visual arts in the early modern period, but the early colonial ventures of the new independent Italy create a new exotic imaginary that is particularly manifest in popular culture. Othello is influenced by new African discourses but it allso exists in a parallel dimension that somehow resists facile political interpretations. The colonial ventures of post-unification and Fascist Italy do not reverberate in any predictable manner in the growing popularity of the play. After World War II new forms of exoticism emerge that will be subverted only by a new postcolonial scenario that also coincides with a re-emergence of racism. Against the respective historical backdrops, we examine the idiosyncratic versions of blackface by Tommaso Salvini, Pietro Sharoff, Pier Paolo Pasolini, Carmelo Bene, and Elio De Capitani to suggest continuities and discontinuities in Italian interpretations of Othello.
“Far more fair than black”: Othellos on the Chilean Stage
Authors: Baldwin Lind Paula
Published: February 2021

This article reviews part of the stage history of Shakespeare’s Othello in Chile and, in particular, it focuses on two performances of the play: the first, in 1818, and the last one in 2012-2020. By comparing both productions, I aim to establish the exact date and theatrical context of the first Chilean staging of the Shakespearean tragedy using historical sources and English travellers’ records, as well as to explore how the representation of a Moor and of blackness onstage evolved both in its visual dimension — the choice of costumes and the use of blackface—, and in its racial connotations alongside deep social changes. During the nineteenth century Othello became one of the most popular plays in Chile, being performed eleven times in the period of 31 years, a success that also occurred in Spain between 1802 and 1833. The early development of Chilean theatre was very much influenced not only by the ideas of the Spaniards who arrived in the country, but also by the available Spanish translations of Shakespeare; therefore, I argue that the first performances of Othello as Other — different in origin and in skin colour — were characterised by an imitative style, since actors repeated onstage the biased image of Moors that Spaniards had brought to Chile. While the assessment of Othello and race is not new, this article contrasts in its scope, as I do not discuss the protagonist’s actual origin, but how the changes in Chilean social and cultural contexts can reshape and reconfigure the performance of blackness and turn it into a meaningful translation of the Shakespearean Moor that activates audiences’ awareness of racism and fears of miscegenation.
The Moor’s Political Colour: Race and Othello in Poland
Authors: Kowalcze-Pawlik Anna
Published: February 2021

This paper provides a brief outline of the reception history of Othello in Poland, focusing on the way the character of the Moor of Venice is constructed on the page, in the first-published nineteenth-century translation by Józef Paszkowski, and on the stage, in two twentieth-century theatrical adaptations that provide contrasting images of Othello: 1981/1984 televised Othello, dir. Andrzej Chrzanowski and the 2011 production of African Tales Based on Shakespeare, in which Othello’s part is played by Adam Ferency (dir. Krzysztof Warlikowski). The paper details the political and social contexts of each of these stage adaptations, as both of them employ brownface and blackface to visualise Othello’s “political colour.” The function of blackface and brownface is radically different in these two productions: in the 1981/1984 Othello brownface works to underline Othello’s overall sense of alienation, while strengthening the existing stereotypes surrounding black as a skin colour, while the 2011 staging makes the use of blackface as an artificial trick of the actor’s trade, potentially unmasking the constructedness of racial prejudices, while confronting the audience with their own pernicious racial stereotypes.

For the purposes of modeling and classification of structures and textures of bimineral rocks, a diagram of a new type is proposed — a barycentric tetrahedron (piii, piij, pijj, pjjj) of probabilities of ternary intergrain contacts. The position of the Hardy-Weinberg equilibrium line is calculated. Correspondences between the classification fields and boundaries in the barycentric tetrahedron and the previously proposed barycentric triangle (pii, pij, pjj) of the probabilities of binary intergrain contacts are established. The prospects for the classification of petrographic structures and textures in a barycentric tetrahedron based on Newton's classification of curves of the 3rd order are discussed.
Religious Security in the Post-Soviet Muslim Space

Published: February 2021

Religious security became one of the important spheres in internal and external political affairs of the post-Soviet Muslim countries during 30 years of their independent development. Each of these states, including Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan, gained their own experience in solving problems of religious security which however had many common features and methods of fighting religious extremism and radicalism. As a result it allowed the above countries to form cooperation in this field during the last decade and to undertake a lot of common practical and legal interstate steps in order to provide their religious security.
Integration of Ukrainian Migrants into Polish Labor Market
Authors: Vedeneeva V.
Published: February 2021

Ukrainian citizens constitute an absolute majority among all categories of foreigners working in Poland. Their employment is largely characterized by over-representation in jobs with poor working and hyper-intensive conditions; by concentration in certain sectors of the economy; by a mismatch between work performed and available qualifications; and by weak legal protection. Limited access to stable employment, work in the «shadow economy», failure of employers to meet their financial obligations, and legal insecurity discriminate labor immigrants. The integration policy consists mainly of scattered events and does not form a coherent, long-term national strategy. While NGOs in several Polish voivodships and individual employers may tackle the issue of migrant integration, only a small proportion of legally employed Ukrainians are covered by integration measures. Short-term migrants and those employed in the “grey zone” are virtually “invisible” to both Polish society and the authorities.

Published: February 2021

We present a general approach to define reproduction ratios or numbers to monitor the outbreak of epidemics that are modeled by mathematical evolution equations. This provides a solution to an important topic that has not been completely settled in the literature, especially in the case of complex epidemiological models. We illustrate our procedure with a full implementation of a standard deterministic SEIR model that is applied to examine the Covid-19 outbreaks and the effects of intervention measures in several countries in America (Argentina, Brazil, Mexico, USA) and Europe (France, Italy, Spain and UK) in 2020. Our code is also used to investigate herd immunity levels for Covid-19, indicating values between 85% and 90%.

Published: February 2021

Various methods of water purification, the aim of which is to obtain such a purity class that makes it suitable for consumption are presented in the article. It is a review of solutions, ranging from methods known and used for over 100 years, through research and experiments underway, to those that are only a concept. Some of the solutions are so effective that they should also be combined with the possibility of safe storage of purified water. Flexible tanks are used for this, which significantly improve logistics and provide a supply of water in all places where it is needed.

Published: February 2021

Background: Hepatocellular carcinoma (HCC) is one of most common cancers with a high mortality rate. HBV/HCV infection is an important risk factor to trigger HCC. Therefore, developing serum biomarkers for early diagnosis is crucial to prolong survival in HCC patients. Methods: An antibody array technology was utilized to detect serum from 20 HBV-related HCC patients, 20 chronic hepatitis B patients and 20 normal population, whose results were further validated by ELISA. Results: Both antibody array and ELISA showed that ten growth factors (SCF R, GDF-15, HGF, FGF-4, IGFBP-1, PIGF, GH, GDNF, BDNF and IGF-1) were significantly differential in HCC patients when compared to the non-HCC population. Among these growth factors, the levels of SCF R, GDF-15, HGF, GH and IGF-1 showed significant correlation with hepatitis B and its severity, indicating that these growth factors may promote HCC progression by an HBV-specific mechanism. A therapy targeting these growth factors in hepatitis B patients may help to prevent the development of HCC. FGF4 and GH were found, for the first time, to be upregulated in HCC, suggesting that these two growth factors may serve as novel serum biomarkers for the early diagnosis of HCC. Conclusion: The combined detection of all the differential growth factors may improve the diagnostic accuracy of HCC.

Published: February 2021

Rapid online surveys are an important tool in tracking the public’s knowledge and perceptions during infectious disease outbreaks. In June 2020, during the early phases of COVID-19 vaccines development, a survey had been conducted, aimed at assessing attitudes and opinions about vaccination of 885 Italian adults, in addition to their vaccine literacy levels (i.e. skills of finding, understanding and using information about vaccines). In January 2021, the same questionnaire has been administered to a similar population (n=160). Interactive vaccine literacy was significantly higher than in June 2020 (mean score 3.38 vs 3.27 respectively, P=.0021). The percentage of participants willing to be vaccinated against COVID-19 was assessed by the means of either-or questions, and was equally high in both surveys (>90%), which is quite reassuring, despite metrics based on categorical scales cannot identify hesitant subjects.
Bacteria-Bacteriophage Cycles Facilitate Cholera Outbreak Cycles: An Indirect Susceptible - Infected - Bacteria - Phage (Isibp) Model-Based Mathematical Study

Published: February 2021

Cholera is an acute enteric infectious disease caused by the Gram-negative bacterium Vibrio Cholerae. Despite a huge body of research, the precise nature of its transmission dynamics has yet to be fully elucidated. Mathematical models can be useful to better understand how an infectious agent can spread and be properly controlled. We develop a compartmental model describing a Human population, a bacterial population as well as a phage population. We show that there might be eight equilibrium points; one of which is a disease free equilibrium point. We carry out numerical simulations and sensitivity analyses and we show that the presence of phage can reduce the number of infectious individuals. Moreover, we discuss the main implications in terms of public health management and control strategies.

A heterogeneous disease like cancer is activated through multiple pathways and different perturbations. Depending upon the activated pathway(s), patients’ survival vary significantly and show different efficacy to various drugs. Therefore, cancer subtype detection using genomics level data is a significant research problem. Subtype detection is often a complex problem, and in most cases, needs multi-omics data fusion to achieve accurate subtyping. Different data fusion and subtyping approaches have been proposed, such as kernel-based fusion, matrix factorization, and deep learning autoencoders. In this paper, we compared the performance of different deep learning autoencoders for cancer subtype detection. We performed cancer subtype detection on four different cancer types from The Cancer Genome Atlas (TCGA) datasets using four autoencoder implementations. We also predicted the optimal number of subtypes in a cancer type using the silhouette score. We observed that the detected subtypes exhibit significant differences in survival profiles. Furthermore, we also compared the effect of feature selection and similarity measures for subtype detection. To evaluate the results obtained, we selected the Glioblastoma multiforme (GBM) dataset and identified the differentially expressed genes in each of the subtypes identified by the autoencoders; the obtained results coincide well with other genomic studies and can be corroborated with the involved pathways and biological functions. Thus, it shows that the results from the autoencoders, obtained through the interaction of different datatypes of cancer, can be used for the prediction and characterization of patient subgroups and survival profiles.
Gravity, Where Does It Come From?
Authors: Isam Ahmed
Published: February 2021

Einstein’s theory of general relativity describes the gravitational field around massive objects ( like Earth) as a curvature in the spacetime. But it leaves the following question unanswered; why is the spacetime curved by a mass? Through a theory that has been introduced recently, regarding a medium for a light propagation, a simple answer is introduced. It depends on redefining the rest energy for a massive object ( like a planet) as new form of kinetic energy. For a static and spherically symmetric object, with a specific radius(

In this study we mimic the unique, transparent protective carapace (shell) of myodocopid ostracods, through which their compound eyes see, to demonstrate that the carapace ultrastructure also provides functions of strength and protection for a relatively thin structure. The bulk ultrastructure of the transparent window in the carapace of the relatively large, pelagic cypridinid (Myodocopida) Macrocypridina castanea was mimicked using thin film deposition of dielectric materials to create a transparent, 15 bi-layer material. This biomimetic material was subjected to the natural forces withstood by the ostracod carapace in situ, including scratching by captured prey and strikes by water-borne particles. The biomimetic material was then tested in terms of its extrinsic (hardness value) and intrinsic (elastic modulus) response to indentation along with its scratch resistance. The performance of the biomimetic material was compared with that of a commonly used, anti-scratch resistant lens and polycarbonate that is typically used in the field of transparent armoury. The biomimetic material showed the best scratch resistant performance, and significantly greater hardness and elastic modulus values. The ability of biomimetic material to revert back to its original form (post loading), along with its scratch resistant qualities, offers potential for a biomimetic eye protection coating that could enhance material currently in use.
