3D Copyright Protection Based on Binarized Computational Ghost Imaging Encryption and Cellular Automata Transform
Authors: Wang Meng , Chen Mengli , Li Jianzhong , Yu Chuying
Published: March 2022

In this paper, a watermark embedding scheme based on ghost image encryption and cellular automata transformation is proposed. In this scheme, the watermark forms speckle through different light intensities into a key, and the cellular automata transformation algorithm is embedded into the 3D image. Compared with the traditional watermarking encryption method, this scheme combines ghost imaging and the cellular automata transformation algorithm, which double guarantees and increases the confidentiality of the watermark. The binary computing ghost imaging discussed in this paper saves the storage space of password text and makes the transmission of password text more convenient and faster. Experiments on this method also verify that the watermark-embedded image has higher imperceptibility and higher robustness against attacks, and that the extracted watermark has good integrity.

Published: March 2022

In this work, Hexagonal Mesoporous Silica (HMS) and Santa Barbara Amorphous-15 (SBA-15) mesostructured silicas were synthesized and functionalized with sulfonic acid groups. The materials (HMS-SO3− and SBA-15-SO3−) were evaluated as strong cation exchange sorbents for sample extract clean-up, by solid phase extraction (SPE) and dispersive solid phase extraction, to determine atropine (At) and scopolamine (Sc) in commercial culinary aromatic herbs. Under optimized conditions, 0.25 g of sample was subject to solid–liquid extraction with acidified water (pH 1.0), and good recovery percentages were achieved for At and Sc using 75 mg of HMS-SO3− in SPE as the clean-up stage, prior to their determination by HPLC-MS/MS. The proposed method was validated in a thyme sample showing recoveries in the range of 70–92%, good linearity (R2 > 0.999), adequate precision (RSD ≤ 14%) and low limits (MDL 0.8–2.2 µg/kg and MQL 2.6–7.2 µg/kg for both analytes). Sixteen aromatic herbs samples (dried thyme, basil and coriander leaves) were analysed and At was found in fourteen samples over an interval of <5–42 μg/kg, whereas Sc was found in three of the sixteen samples studied (between <5–34 μg/kg). The amount of At and Sc found in some analysed samples confirms the importance of setting maximum levels of At and Sc in culinary aromatic herbs.
Venomics Reveals a Non-Compartmentalised Venom Gland in the Early Diverged Vermivorous Conus distans
Authors: Prashanth Jutty Rajan , Dutertre Sebastien , Rai Subash Kumar , Lewis Richard J.
Published: March 2022

The defensive use of cone snail venom is hypothesised to have first arisen in ancestral worm-hunting snails and later repurposed in a compartmentalised venom duct to facilitate the dietary shift to molluscivory and piscivory. Consistent with its placement in a basal lineage, we demonstrate that the C. distans venom gland lacked distinct compartmentalisation. Transcriptomics revealed C. distans expressed a wide range of structural classes, with inhibitory cysteine knot (ICK)-containing peptides dominating. To better understand the evolution of the venom gland compartmentalisation, we compared C. distans to C. planorbis, the earliest diverging species from which a defence-evoked venom has been obtained, and fish-hunting C. geographus from the Gastridium subgenus that injects distinct defensive and predatory venoms. These comparisons support the hypothesis that venom gland compartmentalisation arose in worm-hunting species and enabled repurposing of venom peptides to facilitate the dietary shift from vermivory to molluscivory and piscivory in more recently diverged cone snail lineages.
Bose–Einstein Condensate Dark Matter That Involves Composites
Authors: Gavrilik Alexandre M. , Nazarenko Andriy V.
Published: March 2022

Improving the Bose–Einstein condensate model of dark matter through the repulsive three-particle interaction to better reproduce observables such as rotation curves reveals both different thermodynamic phases and few-particle correlations. Using the numerically found solutions of the Gross–Pitaevskii equation for averaging the products of local densities and for calculating thermodynamic functions at zero temperature, it is shown that the few-particle correlations imply a first-order phase transition and are reduced to the product of single-particle averages with a simultaneous increase in pressure, density, and quantum fluctuations. Under given conditions, dark matter exhibits the properties of an ideal gas with an effective temperature determined by quantum fluctuations. Characteristics of oscillations between bound and unbound states of three particles are estimated within a simple random walk approach to qualitatively model the instability of particle complexes. On the other hand, the density-dependent conditions for the formation of composites are analyzed using chemical kinetics without specifying the bonds formed. The obtained results can be extended to the models of multicomponent dark matter consisting of composites formed by particles with a large scattering length.
The “ER = EPR” Conjecture and Generic Gravitational Properties: A Universal Topological Linking Model of the Correspondence between Tripartite Entanglement and Planck-Scale Wormholes
Authors: Zafiris Elias , von Müller Albrecht
Published: March 2022

The “ER = EPR” conjecture, conceived by Maldacena and Susskind, is grounded on the notion that a gravitational theory in the bulk is dual to the corresponding quantum field theory on the boundary in accordance to the AdS/CFT correspondence. The conjecture pertains to the idea that Einstein-Rosen (ER) spacetime bridges and Einstein-Podolsky-Rosen (EPR) quantum entanglement may be considered as dually equivalent. Since ER bridges refer to the connectivity between black holes, the “ER = EPR” conjecture implies that black holes connected by ER bridges are entangled, and conversely, that entangled black holes are connected by ER bridges. However, the instance of the maximally entangled tripartite (GHZ) quantum state points to the necessity of devising a model of non-classical Planck scale ER bridges going beyond the standard description of these bridges in spacetime. Based on the topological structure of the maximally entangled GHZ state, we propose that a universal topological link, called the Borromean rings, furnishes a particular linking structure that is able to unravel the equavalence between entanglement and wormholes, and thus, to address the validity of the “ER = EPR” conjecture beyond the initial context of the AdS/CFT correspondence. As a consequence, we propose the explicit construction of distinguishable extensions of the smooth classical spacetime manifold taking place in the transition to the quantum gravity regime according to a naturally induced physical criterion of gravitational generic properties following from this intrinsic topological qualification of the “ER = EPR” conjecture.
Can Asteroid Belts Exist in the Luyten’s System?
Authors: Galiazzo Mattia , Silber Elizabeth A. , Dvorak Rudolf
Published: March 2022

The extra-solar planetary system Luyten is relatively close (12.3 light years) to our Sun. The Luyten’s red dwarf star is orbited by four planets, two of them Earth-like (in mass) and in 4:1 resonance. Extra-solar systems might contain asteroid belts such as ours. Therefore, it is important to investigate whether it is possible to have a stable population of minor bodies and compare them to those in our system. The study of extra-solar systems is crucial for understanding the evolution of planetary systems in general. Here, we investigate the stability of two possible asteroid populations in the Luyten’s system: the main asteroid belt between the two inner and two outer planets, and an outer asteroid belt, situated beyond the planets. We also explore the likelihood of observing an asteroid or a dwarf planet in this system. Our study suggests that the existence of asteroid belts is possible, notably the main belt at 0.09–0.53 au from the star and an outer belt (with the inner boundary at 0.85 au and the outer boundary at ∼66,000 au). The average Yarkovsky drift for the Luyten’s main asteroid belt is ∼0.5×10−4 au/Myr for km-size objects. The Luyten’s system might host extra-solar minor bodies, some of which could be capable of entering our own system. Presently, no asteroids can be detected in the Luyten’s system, not even a Ceres-sized body, because the detection signal using the radial velocity method is at least two orders of magnitude less than that required for discerning such objects. The detection probability of an asteroid in the Luyten belt similar to Ceres is about 1.3%, which is less than the probability of finding Luyten B (∼3%).
Spin Precession in the Gravity Wave Analogue Black Hole Spacetime
Authors: Chakraborty Chandrachur , Mukhopadhyay Banibrata
Published: March 2022

It was predicted that the spin precession frequency of a stationary gyroscope shows various anomalies in the strong gravity regime if its orbit shrinks, and eventually, its precession frequency becomes arbitrarily high very close to the horizon of a rotating black hole. Considering the gravity waves of a flowing fluid with a vortex in a shallow basin, which acts as a rotating analogue black hole, one can observe the predicted strong gravity effect on the spin precession in the laboratory. Attaching a thread with the buoyant particles and anchoring it to the bottom of the fluid container with a short-length miniature chain, one can construct a simple local test gyroscope to measure the spin precession frequency in the vicinity of the gravity wave analogue black hole. The thread acts as the axis of the gyroscope. By regulating the orbital frequency of the test gyroscope, one can also measure the strong gravity Lense–Thirring effect and geodetic/de-Sitter effect with this experimental set-up as the special cases. For example, to measure the Lense–Thirring effect, the length of the miniature chain can be set to zero, so that the gyroscope becomes static. One can also measure the geodetic precession with this system by orbiting the test gyroscope in the so-called Keplerian frequency around the non-rotating analogue black hole that can be constructed by making the rotation of the fluid/vortex negligible compared to its radial velocity.

Published: March 2022

In this study, we have presented the genomic characterisation of UFJF_PfDIW6, a novel lytic Pseudomonas fluorescens-phage with potential for biocontrol in the dairy industry. This phage showed a short linear double-stranded DNA genome (~42 kb) with a GC content of 58.3% and more than 50% of the genes encoding proteins with unknown functions. Nevertheless, UFJF_PfDIW6’s genome was organised into five functional modules: DNA packaging, structural proteins, DNA metabolism, lysogenic, and host lysis. Comparative genome analysis revealed that the UFJF_PfDIW6’s genome is distinct from other viral genomes available at NCBI databases, displaying maximum coverages of 5% among all alignments. Curiously, this phage showed higher sequence coverages (38–49%) when aligned with uncharacterised prophages integrated into Pseudomonas genomes. Phages compared in this study share conserved locally collinear blocks comprising genes of the modules’ DNA packing and structural proteins but were primarily differentiated by the composition of the DNA metabolism and lysogeny modules. Strategies for taxonomy assignment showed that UFJF_PfDIW6 was clustered into an unclassified genus in the Podoviridae clade. Therefore, our findings indicate that this phage could represent a novel genus belonging to the Podoviridae family.
Environmental Contamination by Echinococcus spp. Eggs as a Risk for Human Health in Educational Farms of Sardinia, Italy

Published: March 2022

Cystic Echinococcosis (CE) is a severe zoonosis caused by the larval stage of the tapeworm Echinococcus granulosus. These parasites are naturally transmitted between canid definitive hosts that harbour the adult stage in the intestine, and mainly ungulate intermediate hosts, with larval cysts developing in their internal organs. The close coexistence between dog and sheep with incorrect hygiene management are the most important factors for the persistence of this parasitic pathology. The Educational Farms (EF) are farms and agritourisms suitably equipped to carry out training activities for people interested in farm practices and agricultural processing, in particular student groups. Public attendance of farms represents a new potential risk factor for the zoonoses transmission. Consumption of contaminated food and water in combination with contact or playing with domestic dogs (Canis familiaris) are possible routes of zoonoses human infection. In fact, Echinococcus spp. eggs may persist in the environment up to several months at low temperatures and moist conditions, having the chance of contaminating different matrices and surfaces. The aim of this investigation was to study environmental contamination by parasitic elements as a risk for zoonoses, such as Echinococcus spp. A total of 116 samples (35 of water, 33 of soil, 23 of vegetables, 25 of dog faeces) were collected in 30 EF in Sardinia. Samples were subjected to biomolecular investigation for the research of specific gene sequences of Echinococcus granulosus, Echinococcus multilocularis and Taenia spp. The study allowed to identify eight positive EF due to the presence of Echinococcusgranulosus in eight dog faeces samples and one positive EF due to the presence of Taenia spp. in a water sample. The work has allowed to develop and harmonise the diagnostic methods and operating protocols essential for controlling the spread of the CE to create “One Health” intervention plans in high endemic areas through the implementation of SOP (standard operating procedures) for monitoring the pathology in animals, humans and environment.

Mandibular protrusion and its treatment is challenging for the orthodontist. The aim of the present research was to identify macroscopic changes in the mandible, based on three-dimensional Cone Beam Computed Tomography analysis. Seventy-two male Wistar rats were divided into two equal groups, experimental (group A) and control (group B). Each consisted of three equal subgroups of 12 rats (A1, A2, A3, B1, B2, B3). Full-cast orthodontic intraoral devices were attached to the maxillary incisors of the experimental animals, and effected functional posterior mandibular displacement. Throughout the experimental period, all animals were fed with mashed food. Animals were sacrificed at 30 days (A1, B1), 60 days (A2, B2) and 90 days (A3, B3). At the 60th day of the experiment, the orthodontic devices were removed from the remaining experimental subgroup A3. Measurements revealed significant differences in the anteroposterior dimensions between experimental and control subgroups. However, the observed changes in the vertical dimensions, Condylion/Go’–Menton and the Intercondylar distance proved insignificant. Posterior mandibular displacement of the mandible in growing rats affects the morphology of the mandible and culminates in the development of a smaller mandible at a grown age.

Contamination of laboratory surfaces with nucleic acids and their amplicons is one of the most important problems encountered in nucleic acid amplification methods due to the occurrence of unreliable results. The aim of this study was to select and determine effective regimens for the use of various active agents for decontamination in PCR laboratories. The ability of ethyl alcohol, alkyldimethylbenzylammonium chloride, N,N-bis(3-aminopropyl)dodecylamine, polyhexamethyleneguanidine hydrochloride, hydrogen peroxide, peracetic acid, chlorine dioxide, sodium hypochlorite and neutral anolyte to destroy or irreversibly modify DNA, preventing its subsequent amplification was studied. The decontamination activity was analyzed by simulating the surface contamination with both long (1500 bp) and short (94 bp) amplicons. Hydrogen peroxide 2?%, peracetic acid 0.24?%, dichloroisocyanuric acid 0.01?%, sodium hypochlorite 0.1?% and chlorine dioxide 0.01?% were shown to have decontaminating ability. Notably, dichloroisocyanuric acid decontaminated surfaces from DNA at a concentration 20 times lower than previously described, and sodium hypochlorite at half the concentration, and chlorine dioxide was also found to have decontaminating activity. The absence of decontaminating activity was observed in ethyl alcohol 70?%, alkyldimethylbenzylammonium chloride 2?%, N,N-bis(3-aminopropyl)dodecylamine 2?%, polyhexamethyleneguanidine hydrochloride 2?% and neutral anolyte 0,05?%.

The sporicidal and bactericidal effect of hydrogen peroxide using a hot fog generator on the viability and ultrastructure of spores of the vaccine strain Bacillus anthracis STI-1 was studied using a bacteriological method and electron microscopy. The high efficiency of disinfection treatment of various surfaces has been established, which consists in the fact that within 10-20 minutes there is a complete death of test microorganism that contaminate the surfaces treated with hot fog. It has been experimentally proven that in the process of generating hot fog, the concentration of working disinfectant solution increases, which is based on the partial evaporation of moisture from solution of disinfectant during the formation of hot fog and its transfer by a stream of hot gas. Based on the results obtained, it is advisable to use hot fog generators to achieve a pronounced biocidal effect when carrying out disinfection measures in medical organizations, as well as when performing scientific research.

ECONOMIC GROWTH AND HUMAN DEVELOPMENT IN OECD COUNTRIES: A TWENTY-YEAR STUDY OF DATA 2000–2019
Authors: METZGER Nicola , SHENAI Vijay
Published: March 2022

The aim of the current research is to determine the factors and processes which influence economic growth and human development in relatively free societies and thereby provide a framework for policy formulation. Countries within the OECD grouping are committed to democratically elected government and market economies and fall into this category. The OECD group comprises 37 countries, including Colombia, and in 2019 accounted for 63% of real global GDP. This research focuses on the data of the thirty-seven countries over the twenty-year period of 2000-2019. Economic data is drawn from the World Bank and the IMF websites; whilst data on development indicators and income inequality is drawn from the UNDP (United Nations Development Programme) and WID (World Inequality database) websites. Analysis of the data in these countries provides insights into the factors and processes which influence economic growth and human development in economies with a democratic political regime. The estimated equation shows that economic growth in OECD countries was significantly higher when incoming investment as a proportion of the size of the economy and openness of the economy were higher, inflation, exchange rate changes and oil prices were lower. Smaller economies in the OECD also had higher economic growth. As the aim of a government is to increase not only the income but also the standard of living of its citizens, it is necessary also to assess the relationship between economic growth and the quality of life and wellbeing of its citizens. Five-year average cross-sectional regressions also show that economic growth in OECD countries is higher in the countries with lower HDI. This report further finds that economic growth has a bi-directional causality with changes in the human development index, and changes in life expectancy and a unidirectional causality with changes in the expected years of schooling (implying higher delivery of education) and changes in the standard of living. Another finding is that income inequality increases with economic growth; both in terms of the share of income of the top 10% and share of the lower 50%. Clearly investment in public goods, and social policies for education, skills training, healthcare and redistribution of wealth need more attention.
INNOVATION PARTNERSHIP MECHANISMS: EUROPEAN EXPERIENCE IN THE CONTEXT OF DEVELOPMENT OF UKRAINE’S EUROPEAN INTEGRATION
Authors: YERMAKOVA Olha
Published: March 2022

The paper investigates the mechanism of operation of European innovation partnerships, which are a new organizational element aimed at creating market opportunities through increased cooperation of stakeholders in the crosssectoral, cross-industrial and inter-territorial contexts. This contradicts the traditional approach to supporting innovation through direct state financing. The European experience of innovation partnerships is valuable for Ukraine due to its effectiveness, systemic nature, scale and institutional support. The author’s experience of creating a Ukrainian-Moldovan cross-border cluster for wine waste processing is used to conduct a comparative analysis of the institutional framework for the creation and operation of European and Ukrainian innovation partnerships. The obtained results determine directions for development, namely creation of national platforms of innovation partnerships in target areas, integration of platforms at various levels (local, regional, national, cross-border, European), establishment of the institute of innovation brokerage and creation of permanent consulting / brokering services in the innovation sector, involvement of sectoral regional programmes and their resources in creating innovation partnerships, and development and adoption of a national concept and programme of building innovation partnerships.
UKRAINE’S EUROPEAN INTEGRATION IN THE FIELD OF RESEARCH AND INNOVATION: STATE, CHALLENGES, ACCELERATION MEASURES
Authors: PIDORYCHEVA Iryna
Published: March 2022

Unprecedented complexity of the modern challenges requires the international community to strengthen cooperation in science, technology and innovation to better seize the opportunities and reap the benefits of the new reality, as well as search for new solutions to problems humanity is faced with. The paper investigates the influence of European integration on the economy and innovation ecosystem of Ukraine. It is established that the innovative component of the national economy has contracted over 2015-2020. With each year, it is becoming more primitive and de-industrialized, which necessitates a revision of the Association Agreement with the EU aimed at enhancing its positive impact on innovation processes in the national economy. Conducted analysis allows for comparisons between Ukraine’s involvement in the Horizon 2020 Framework Programme, which remains low, and that of EU member states and other associated members. Ukraine’s predicament is explained by, among other reasons, a weak national innovation ecosystem and a lack of close contact and professional ties between Ukrainian institutions and their European counterparts. The paper offers suggested solutions to these problems, namely a set of organizational and institutional measures that will broaden Ukraine’s access to EU funding and accelerate integration into European Research Area. The author emphasizes the need for planned systemic reforms in order to overcome the structural weakness of the national economy. «Natural» development of science and technology, revitalization of the industries though introduction of latest technologies, preservation and balanced development of human capital will all ensure Ukraine’s advancement through development of a competitive high-technology economy.
IMPACT OF TAXES ON THE EXPORT-IMPORT TENDENCIES IN THE COUNTRIES OF THE EU IN UNSTABLE PRESENT-DAY
Authors: DUBROVINA Nadiya , DUBROVINA Vera , SHELEST Oleksii , TULAI Oksana
Published: March 2022

The problem of rationales for taxes and transfers is given a lot of attention by both researchers and politicians. Taxes are one of the main sources of government revenue and are considered a strong resource for welfare state. Taxes have an impact on the development of international trade and business, as the latter chooses a more attractive location with less tax burden and costs. Nevertheless, the country’s status, competitiveness of industries, development of the infrastructure, safety and transparency are also important factors for the domestic and foreign business and investors. That is why it is necessary to study the impact of taxes on the export and import policy. In this article we study the development of export-import tendencies in the EU countries over the period from 2002 to 2018. Statistical calculations are done for EU-28 countries. The results show that values of tax revenues as percentage of GDP change slowly and diverge little from set levels. A corresponding pattern is evident in the main tax categories, however the fiscal lag for direct taxes, indirect taxes and social contributions differs. Research indicates that different export-import strategies prevail across the EU countries, as do systems of taxation. A system of two equations is basis for the model, which uses the econometric approach to assess the impact of taxes on the development of export-import tendencies in the EU. The analysis proves that if tax rates on exports are reduced in the short term, there is a positive effect on the intensity of export activities, but this may increase the dependence of the national economy on foreign markets both in the short and in the long term. Thus, reductions in import tax rates, on the one hand, help to strengthen the competitiveness of domestic producers in foreign markets, and on the other, intensify competition in the domestic market.

"Medicinal plants have played an important role in the development of human health care and culture, serving as both medicine and food. Herbal drugs have been used for centuries for the treatment of several diseases and many of the new medicines are produced based on recent research on their traditional uses. Medicinal plants of the Middle East are regarded as a rich resource of different valuable bioactive compounds. Such compounds extracted from natural resources maintain many potential health beneﬁts. The application of bioactive compounds is, however, rather limited in food and drug formulations because of their poor bioavailability, fast release and low solubility. Thus, encapsulation can protect the bioactive compounds from environmental stress, improve their physicochemical functionalities, reduce the potent toxicity of drugs, modify the release of encapsulated active materials, reduce dosage, enhance their health-promoting and anti-disease activities. This review discusses the importance of the pharmaceutical properties of thirty-two species of relevant medicinal plants native to the Middle East and their uses in various industrial applications. "

"Studies on cellulose/nanocellulose obtained from oil meals are very limited, but present interest and have scientific significance, since the structure, properties and performance may be different from those of other cellulose or nanocellulose types. Thus, the main objective of this work was to extract nanocellulose from an unconventional source – oil meal. Oil meals contain about 20-25% carbohydrates, but the structure and properties of the cellulose from oil meals has not been reported so far. In this research, we have extracted nanocellulose (particles and fibers) from Pongamia pinnata oil meal by alkali treatment, bleaching, and acid treatment. The cellulose obtained after bleaching and the final nanocellulose achieved after acid treatment were thoroughly characterized to determine their composition, structure and properties. Morphological studies using TEM and AFM proved the presence of nanostructures in the form of nanoparticles and nanorods. The average effective diameter and mean zeta potential, according to dynamic light scattering experiments, were found to be 338 nm and -13.3 mV, respectively. The weight average molecular weight and degree of polymerization obtained from SEC MALLS were 54,300 and 335, respectively. Higher thermal stability and reduced crystallinity of nanocellulose, in comparison with cellulose, were observed. Overall, a comparative report on the characterization of nanocellulose extracted from Pongamia pinnata, with its respective cellulose, has been provided here."

"Cellulose is the most abundant biopolymer in our world, and a natural, biodegradable and inexpensive resource for biomaterials. This work prepared cellulose-based hydrogels by cross-linking cellulose derivatives using citric acid, succinic acid, and sebacic acid, and explored the rheological properties of the three cellulose-based hydrogels. We found that the viscoelastic properties of this kind of cellulose-based biodegradable hydrogels can be manipulated by hydrogel concentration and using the three different cross-linkers. The cellulose-based hydrogels cross-linked with citric acid (CHCCA) and the cellulose-based hydrogels cross-linked with succinic acid (CHCSUA) exhibited nearly identical rheological behaviors (both linear and non-linear), due to the similar structure of the citric acid and succinic acid. Both CHCCA and CHCSUA showed similar viscoelastic solid gel-like behaviors, and the viscoelastic properties were stronger when hydrogel concentrations were increased. The CHCCA and CHCSUA also displayed nearly identical shear thinning behaviors, among all measured shearing rates. The cellulose-based hydrogels cross-linked with sebacic acid (CHCSEA) exhibited viscoelastic liquid or fluid-like behaviors, which are clearly different from those for the CHCCA and CHCSUA. The CHCSEA showed shear thinning characteristics during high shearing rates, but a Newtonian region at low shearing rates. This work paves the way for developing various inexpensive biodegradable cellulose-based hydrogels with desired rheological properties specific to applications such as cosmetic gels and woundhealing materials."

"Nanofibrillated cellulose can be used as a robust scaffold filled with tannin particles. Such reinforcement may confer particular chemical features needed for the production of hybrid films used as active packaging. Based on this hypothesis, powdered tannin particles were incorporated into nanocellulose-based films at two different weight fractions. The chemical, thermal and mechanical properties of these films were determined. Also, their resistance to UV exposure was evaluated in terms of colorimetric and mechanical characteristics. Neither chemical nor thermal noticeable adverse effects could be ascribed to the tannin insertion. On the other hand, the insertion of 1 wt% tannin induced an increase of 60% in tensile strength, although this effect was not retained after UV exposure. Meanwhile, the film that incorporated 3 wt% tannin appeared to present stable mechanical properties after UV exposure. This mechanical stability over UV exposure was not obtained with the inclusion of 1 wt% tannin content. The hybrid nanofilms acquired brown shades, which were not retained when the films were exposed to UV radiation."
