МЕТОД АДАПТИВНОГО БАГАТОШАРОВОГО ЗАХИСТУ ІНФОРМАЦІЇ НА ОСНОВІ СТЕГАНОГРАФІЇ ТА КРИПТОГРАФІЇ

An analysis of known solutions to the problem of steganographic and cryptographic methods combining to achieve multilayer information protection is presented. Results of the analysis allowed us to identify trends and prospects for the development of these kink of methods. Based on the results of the analysis, the research task was determined concerning the adaptation of the used cryptographic and steganographic methods in order to achieve the best level of protection, which is needed at critical systems. Metrics were defined, those allowed to choose the best combination of cryptographic and steganographic protection methods parameters. A method of multilayered information protection is presented, which combines cryptographic and steganographic approaches to ensure an increased level of information’s confidentiality and integrity protection. It is proposed to introduce criteria for the selection of cryptographic transformations in such a way that their combination together with steganographic transformations gives the best impact. An instance of the proposed method implementation is given in order to prove the concept. An algorithm has been developed that implements the proposed method of adaptive multilayer information protection. The perspective of further research is determined.

Health risk assessment following exposure of operators to backpack-sprayed prothioconazole and its major metabolite in wheat fields in China

Introduction: Prothioconazole is a triazolinthione fungicide widely used to control diseases on various crops caused by Ascomycetes, Basidiomycetes, and Imperfecti fungi. However, in view of the rapid transformation of parent prothioconazole to its major metabolite prothioconazole-desthio during application and the fact that the latter is of higher toxicity, prothioconazole poses a potential threat to the health of operators in direct contact with it. Currently, very few studies have been carried out regarding prothioconazole and prothioconazole-desthio exposure.Methods: Therefore, a typical exposure scenario from wheat-planting provinces in China was chosen, and a motorized backpack-type sprayer was used as the application equipment. The actual exposure doses of prothioconazole and prothioconazole-desthio for mixers/loaders and applicators under different exposure routes were determined, and a tiered risk assessment was conducted considering different conditions.Results: The results of this study indicated that the exposure risk to operators after spraying with 30% prothioconazole oil dispersion was unacceptable in the primary risk assessment, while the risk was acceptable with integrated risk quotients less than 1 at a better level of protection. Moreover, the upper legs and hands were regarded as the most contaminated sections during the mixing/loading process, and legs were the most contaminated sections during spraying. Good protection equipment, such as hats, long-sleeve shirts, long pants, socks, shoes, and rubber or nitrile gloves, was effective at alleviating prothioconazole and prothioconazole-desthio exposure. This study aims to provide important references for the safe use and risk management of prothioconazole.

Implementing Data Exfiltration Defense in Situ: A Survey of Countermeasures and Human Involvement

In this article we consider the problem of defending against increasing data exfiltration threats in the domain of cybersecurity. We review existing work on exfiltration threats and corresponding countermeasures. We consider current problems and challenges that need to be addressed to provide a qualitatively better level of protection against data exfiltration. After considering the magnitude of the data exfiltration threat, we outline the objectives of this article and the scope of the review. We then provide an extensive discussion of present methods of defending against data exfiltration. We note that current methodologies for defending against data exfiltration do not connect well with domain experts, both as sources of knowledge and as partners in decision-making. However, human interventions continue to be required in cybersecurity. Thus, cybersecurity applications are necessarily socio-technical systems that cannot be safely and efficiently operated without considering relevant human factor issues. We conclude with a call for approaches that can more effectively integrate human expertise into defense against data exfiltration.

Evaluating the impact of water protection policy on urban growth: A case study of Jiaxing

Source water protection can be a greater challenge in cities where the hydric resource is deeply embedded within a rapidly growing urban area. In these types of cities, the delimitation of protection areas along water resources, as one of the main mechanisms for water resource protection, has a direct impact on the way the urban form evolves. On the one hand, narrow protection areas may not be enough to guarantee that the built city does not affect water levels and quality. On the other hand, wide protection areas can result in a fragmented city, with low levels of accessibility and tendencies towards dispersed and disorderly growth. In this article we use the city of Jiaxing, China, as a case study to determine what the optimal size of water protection areas might be. For this, we use two urban growth models and simulate various urban growth scenarios between 2020 and 2040. The results indicate that a protection area of 400 m guarantees a good level of protection of the water resource and a sufficient availability of land that allows an efficient urban growth.

Encapsulation of bioactive compounds extracted from date palm seeds (Phoenix dactylifera L.) and their use in functional food.

Liposomes have been used as a novel phytoconstituent delivery system to encapsulate lyophilized palm seed phenolic extract (PSPE) and incorporate it into yogurt as a food model to enhance the bioavailability of PSPE. Phenolic compounds were extracted with aqueous ethanol from palm seed powder using the solvent-maceration approach assisted by ultrasonication. Lyophilized PSPE (0.2-1% w/v) was enclosed in a liposome structure coated with or without chitosan (primary/secondary liposome). Particle size, zeta potential, encapsulation efficiency (EE), Fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM) were applied to investigate the primary and secondary liposomes. To assess the in vitro bioaccessibility of PSPE and primary/secondary liposomes, the total phenolic content (TPC) and the antioxidant activity were studied during the oral, gastric, and intestinal digestion stages. Three concentrations of lyophilized secondary liposomes (1.25, 2.5, and 3.75% w/v) were added to the yogurt food model. During the 14 days of storage, the physical, chemical, and sensory properties were assessed. Compared to the primary liposomes (87%), the secondary liposomes (91%) showed a higher encapsulation efficiency. Comparing the secondary liposomes to the original liposomes and the non-encapsulated PSPE, the bioaccessibility of phenolic compounds was improved. Fortified yogurt with secondary liposomes had a lower syneresis and viscosity than the reference yogurt. The encapsulated PSPE provided a good level of protection, and its release increased throughout the intestinal phase. Thus, PSPE in a microencapsulated form has been proven to be a rich and cost-effective source of phenolics that can be used successfully to produce functional yogurt.

Pathological Evaluation of Porcine Circovirus 2d (PCV2d) Strain and Comparative Evaluation of PCV2d and PCV2b Inactivated Vaccines against PCV2d Infection in a Specific Pathogen-Free (SPF) Yucatan Miniature Pig Model.

Porcine circovirus type 2 (PCV2) is an economically important swine pathogen that causes porcine circovirus-associated diseases (PCVADs). The objective of this study was to evaluate the use of specific pathogen-free Yucatan miniature pigs (YMPs) as an experimental model for PCV2d challenge and vaccine assessment because PCV2-negative pigs are extremely rare in conventional swine herds in Korea. In the first experiment, every three pigs were subjected to PCV2d field isolate or mock challenge. During three weeks of experiments, the PCV2d infection group exhibited clinical outcomes of PCVAD with high viral loads, lymphoid depletion, and detection of PCV2d antigens in lymphoid organs by immunohistochemistry. In the second experiment, three groups of pigs were challenged with PCV2d after immunization for three weeks: a nonvaccinated group (three pigs), a PCV2b-Vac group vaccinated with a commercial PCV2b-based inactivated vaccine SuiShot® Circo-ONE (five pigs), and a PCV2d-Vac group vaccinated with an experimental PCV2d-based inactivated vaccine (five pigs). During the three weeks of the challenge period, nonvaccinated pigs showed similar clinical outcomes to those observed in the PCV2d infection group from the first experiment. In contrast, both the PCV2b and PCV2d vaccinations produced good levels of protection against PCV2d challenge, as evidenced by reduced viral loads, improved growth performance, high virus-neutralizing antibody titers, and less development of PCV2-associated pathological lesions. Taken together, these data suggest that YMPs could be an alternative model for PCV2 challenge experiments, and these animals displayed typical clinical and pathological features and characteristics of protective immunity induced by the vaccines that were consistent with those resulting from PCV2 infections in conventional pigs.

Design of a child restraint system embedded in a sedan vehicle

The accident data referring to deceased infants, who do not have a child restraint system that complies with safety devices, are alarming. Although the current child restraint systems present a good level of protection, it is possible to design systems that improve the performance of the current ones, the improvement in safety being the main motivation for this study. This child restraint system will be incorporated into a sedan car, taking into account the characteristics of the positioning and folding in the rear seat of a sedan vehicle. This research is organized in two phases: the first corresponds to the design of a folding infant carrier system prototype, and the second stage shows the operation of this mechanism through its verification focused on the kinematic study.

Protecting Women’s Rights and Ensuring Gender Equality

In recent decades, the international community and the European Union have paid increasing attention to ensuring a sufficiently good level of protection of women’s rights. To achieve this level, international and European bodies and institutions should draw up and adopt various acts and instruments aimed at ensuring the fundamental principle of gender equality. For example, in European Union law, the principle of equality between men and women is reflected in Articles 2 and 3 (3) of the Treaty on European Union (TEU). These provisions explicitly state that the EU is based on certain values, including equality, and specifically promote equality between men and women. The Treaty on the Functioning of the European Union (TFEU) also provides for a separate provision which entrusts the Community with the task, in all its activities, of striving to eliminate inequalities and to promote equality between men and women (Article 8 of the TFEU). Next, Article 21 of the EU Charter of Fundamental Rights prohibits all forms of discrimination, including on the grounds of sex. In addition to the provisions of primary law, the EU seeks to ensure the principle under analysis by adopting strategies and programs of different scope and content. The Member States of the European Union, including the Republic of Bulgaria, also actively promote respect for the principle of gender equality. Explicit guarantees for its provision are contained in the legislation of the Member States, including at the constitutional level. Despite the measures taken on a global, European and national scale, the unequal treatment of women around the world persists. Most often, differences in the treatment of men and women are observed in the social sphere, employment and pay, healthcare, access to education, political, economic and social activities. The existence of these differences leads to the conclusion that it is necessary for the international community, the European Union and its Member States to adopt and implement even more targeted actions, policies and measures to ensure adequate protection of women’s rights.

Migration routes, behavior and protection status of Eurasian Spoonbills (Platalea leucorodia) wintering in China

BackgroundThe Eurasian Spoonbill (Platalea leucorodia) occurs throughout Eurasia and North and sub-Saharan Africa, with three recognized subspecies and six geographically distributed populations. However, in China, we knew almost nothing about migration routes, habitat use and effectiveness of current site protection measures for this species.MethodsWe deployed Global Positioning System/Global System for Mobile Communications (GPS/GSM) satellite trackers on 29 Eurasian Spoonbills captured in summer in Mongolia and northeastern China, to obtain complete migration routes data from 10 individuals from 19 complete migration episodes.ResultsTracking data showed no geographical overlap during the annual cycle in Eurasian Spoonbills marked in the two main summering areas. Birds marked in the Naoli River Basin in Heilongjiang Province, China, wintered along the Jiangsu coastline in China, while Eurasian Spoonbills from two discrete summering areas (in Inner and western Mongolia) overwintered inland in the Yangtze River floodplain of China. Excluding the single Inner Mongolian bird, spring migration was significantly faster than autumn migration in the other two groups of birds. Eurasian Spoonbills mainly used water, wetland and grassland habitats in summer, but almost exclusively water in winter. Lack of protection of staging sites used by all the birds in spring and poor levels of protection throughout the annual cycle for western Mongolian birds (5–22%) gives considerable cause for concern, although sites used in other time by East Mongolian and Naoli River birds in the rest of their annual life cycle enjoyed good levels of protection (49–95%).ConclusionsThese results revealed previously unknown relationships between summering and wintering areas, migration routes and stopover sites for Eurasian Spoonbills wintering in China, suggesting the existence of discrete biogeographical population units. They also identified winter habitat use of Eurasian Spoonbills in China, confirming open water habitats as being critical throughout the annual cycle, although based on small sample size, gaps in current site safeguard networks for these populations.

This article deals with software attacks targeting multiprocessor systems-on-chip and proposes a set of countermeasures corresponding to lightweight mechanisms characterized by a small impact on the system performance and area, while still guaranteeing a good level of protection.

Oil Spill Response in Remote Inland Locations

Abstract There are many factors that contribute to the complexity of co-ordinating effective oil spill response in remote locations. This poster will focuses on the complexities associated with unique risks encountered in remote locations, with an emphasis on water resources. The hydrogeological setting must be understood if oil spill response organisations (OSRO) are to co-ordinate a response that affords the environment and local populations the best level of protection. The relationship between communities and their environment should be clearly understood as part of preparedness work. This will facilitate the implementation of a suitable and timely response with pre-defined ‘end-points’.

A new candidate vaccine for human brucellosis based on influenza viral vectors: a preliminary investigation for the development of an immunization schedule in a guinea pig model

BackgroundA new candidate vector vaccine against human brucellosis based on recombinant influenza viral vectors (rIVV) subtypes H5N1 expressing Brucella outer membrane protein (Omp) 16, L7/L12, Omp19 or Cu–Zn SOD proteins has been developed. This paper presents the results of the study of protection of the vaccine using on guinea pigs, including various options of administering, dose and frequency. Provided data of the novel vaccine candidate will contribute to its further movement into the preclinical stage study.MethodsGeneral states of guinea pigs was assessed based on behavior and dynamics of a guinea pig weight-gain test. The effectiveness of the new anti-brucellosis vector vaccine was determined by studying its protective effect after conjunctival, intranasal and sublingual administration in doses 105 EID50, 106 EID50 and 107 EID50 during prime and boost vaccinations of animals, followed by challenge with a virulent strain of B. melitensis 16 M infection. For sake of comparison, the commercial B. melitensis Rev.1 vaccine was used as a control. The protective properties of vaccines were assessed by quantitation of Brucella colonization in organs and tissues of infected animals and compared to the control groups.ResultsIt was observed a gradual increase in body weight of guinea pigs after prime and booster immunization with the vaccine using conjunctival, intranasal and sublingual routes of administration, as well as after using various doses of vaccine. The most optimal way of using the vaccine has been established: double intranasal immunization of guinea pigs at a dose of 106 EID50, which provides 80% protection of guinea pigs from B. melitensis 16 M infection (P < 0.05), which is comparable to the results of the effectiveness of the commercial B. melitensis Rev.1 vaccine.ConclusionsWe developed effective human vaccine candidate against brucellosis and developed its immunization protocol in guinea pig model. We believe that because of these studies, the proposed vaccine has achieved the best level of protection, which in turn provides a basis for its further promotion.

Selecting the best quality inspection alternative based on the quality, economic and environmental considerations

The use of inspection is unavoidable in many situations. For example, inspection is required to satisfy government regulation, guarantee quality parameter is met by the products supplied by new suppliers whose quality history has not been built, and mitigate product liability risks. There are three quality inspection alternatives, 100 percent inspection, no inspection, and sampling inspection. No inspection brings a considerable risk of shipping non-conforming products to the consumer. 100 percent inspection involves a slight risk of delivering non-conforming products to the consumer but consumes resources significantly. Sampling inspection requires the producer to judge products based on a random sample. Therefore, it still contains the risk of sending non-conforming products to the consumer. The risk and resource consumptions can cause the producer to bear for the cost and environmental impact due to rework, scrap, and transportation. This paper proposes a mathematical model and algorithm to select the best inspection alternative based on quality, economic, and environmental considerations. We apply the model and algorithm to solve a real industrial case study. The results of the case study show that the proposed method results in a lower expected total cost and CO2 emission and a better level of protection for the producer and consumer than the single sampling plan method widely used. We expect that the proposed model and algorithm can assist practitioners in the industry to select the best inspection alternative. It is essential to note that sampling inspection is not a substitute for proper process monitoring and control.

Antiviral Essential Oils Incorporated in Nanocarriers: Strategy for Prevention from COVID-19 and Future Infectious Pandemics.

Coronavirus has become a life-threatening disease and it is caused by severe acute respiratory syndrome (SARS). This new strain of coronavirus is not completely understood and to date, there is no treatment for coronavirus. Traditional ayurvedic medicines, mainly essential oils and Chinese herbs, have always played a vital role in the prevention and treatment of several epidemics and pandemics. In the meantime, guidelines of the ministry of AYUSH (Ayurveda, yoga, unani, siddha and homoepathy) include a traditional medicinal treatment for flu and fever and also recommended to boost immunity to prevent the spread of coronavirus. It is not possible to find which essential oil will offer the best level of protection. However, it is likely to assume that some essential oils are likely to offer a measurable level of defense in the same way they do with many other known viruses. Literature relevant to various essential oils having antiviral activity has been collected and compiled. Various nanocarriers of essential oils have also been stated. The database was collected using various search engines such as J-Gate, Google Scholar, Sci-Hub, PubMed, ScienceDirect, etc. Results: Essential oils contain active constituents such as phenolic compounds, terpenoids, alkaloids, phenyl propanoids, etc., which are responsible for their biological properties such as antiviral, antibacterial, antimicrobial, antioxidant activities and many more. However, the use of essential oils has always been limited due to poor solubility, solvent toxicity, volatility and low solubility. Many nanotechnology based carriers especially, liposomes, dendrimers, nanoparticles, nanoemulsion and microemulsion, etc. have been evidenced to overcome limitations associated with essential oils. Several essential oils possess potent antiviral activity and are characterized by fewer side effects and are safe for human use. The nanocarrier systems of these oils have proved the potential to treat viral and bacterial infections. Lay Summary: Current COVID-19 era demands traditional treatment for immunity boost up as support therapy. Traditional ayurvedic medicines, mainly essential oils and Chinese herbs, have always played a vital role in the prevention and treatment of several epidemics and pandemics. Therefore, authors have summarized various essential oils having antiviral activity in current manuscript. Various nanocarriers of essential oils have been reported. Essential oils contain active constituents such as phenolic compounds, terpenoids, alkaloids, phenyl propanoids, etc., which are responsible for their biological properties such as antiviral, antibacterial, antimicrobial, antioxidant activity. However, the use of essential oils has always been limited due to poor solubility, solvent toxicity, volatility and low solubility. Many nanotechnology based carriers especially, liposomes, dendrimers, nanoparticles, nanoemulsion and microemulsion, etc. have been evidenced to overcome limitations associated with essential oils. The nanocarrier systems of these oils have proved the potential to treat viral and bacterial infections.

Challenges in Harmonized Assessment of Heavy Metals in the Adriatic and Ionian Seas

The Adriatic-Ionian region (ADRION Region) shows strong development in terms of urban expansion in coastal and inland areas as well as increasing maritime traffic and offshore hydrocarbon extraction activities. A serious risk of pollution arises from hazardous substances requiring reliable and coherent monitoring and assessment programmes. EU Directives (WFD - Water Framework Directive, MSFD - Marine Strategy Framework Directive) and Barcelona Convention protocols, aim to assess the level of pollution with the objective to implement measures to prevent and/or mitigate impacts on the marine environment. This high level integration process has to be based on common and agreed protocols for monitoring of contaminants. Aiming to share best practices to encourage a harmonized implementation of monitoring and assessment of contaminants, an extensive review of monitoring and analytical protocols adopted by six EU and non-EU countries along the Adriatic and Ionian seas was carried out in the framework of the Interreg Adrion project HarmoNIA. This paper presents a methodological proposal to define a common protocol for the evaluation of the metal contamination of seawater, sediment and biota. Contaminants have been chosen following preliminary consultations among countries of the ADRION area, considering objectives of WFD and MSFD, as well as Environmental Impact Assessment (EIA) procedures for offshore platforms. Information was gathered relative to matrix characteristics and quality assurance/quality control of the analytical performance (sample preservation, analytical methodology, reference materials, limit of detection and limit of quantification, accuracy, reproducibility, etc.). The comparison of information provided by laboratories of nine institutions highlighted the request for harmonization in terms of sampling procedures, matrix characterization, preservation procedures, analytical methods and LOQ values. Although appropriate environmental quality standards for biota and sediment matrices should be established at national level and also through regional and sub-regional cooperation, as required by the WFD and MSFD, the proposed LOQ values, even if challenging, represent a benchmark and a stimulus to optimize analytical performance, to ensure the best level of protection to the coastal and offshore environment in the ADRION Region.

Do Slit-Lamp Shields and Face Masks Protect Ophthalmologists amidst COVID-19?

Efficacy of Infectious Bronchitis GI-13 (793B) Vaccine Candidate Tested According to the Current European Union Requirements and for Cross-Protection Against Heterologous QX-Like Challenge.

Infectious bronchitis (IB) is a highly contagious viral disease of chickens, known to cause severe economic losses. Vaccination against IB virus (IBV) is an important control measure against the disease. The objective of the present study was to test Avishield IB GI-13, the vaccine candidate against IBV, strain V-173/11 (GI-13 genotype), according to European Pharmacopoeia (Ph. Eur.) efficacy requirements. Laboratory study on specific-pathogen-free (SPF) chickens showed 100% protection against challenge 10 days after vaccination of 1-7 day-old chickens by three recommended routes. Duration of immunity was shown to be at least 8 weeks after vaccination. Chickens with maternally derived antibodies (MDA) were 100% protected against challenge 21 and 35 days after vaccination. Testing of the vaccine candidate in field conditions on commercial broiler and layer farms showed 80-90% protection against homologous challenge after spray (broilers and layers) or oral (broilers) vaccine administration. Serum antibodies were monitored during the studies, and although good seroconversion was observed in MDA-positive chickens 34 days after vaccination or later, the data from SPF chickens indicate that non-humoral immunity is important in protection against challenge. Neutralizing antibodies in tears were detected, however, their level could not be fully linked with individual protection scores. A cross-protection study showed that administration of the combination of Avishield IB H120 vaccine and Avishield IB GI-13 vaccine candidate at day 1, confers good protection against heterologous QX-like challenge. Stability of the vaccine after reconstitution in 0.2% skimmed milk solution or distilled water at room temperature was confirmed over the period of 3 h. The vaccine candidate fully complied with Ph. Eur. requirements, with very good protection levels, indicating that it can be administered already at 1 day of age by spray at the hatchery or at 7 days of age by drinking water on the farm.

Are there viable chemical and non-chemical alternatives to the use of conventional insecticides for the protection of young trees from damage by the large pine weevil Hylobius abietis L. in UK forestry?

Abstract In UK forestry, the synthetic pyrethroid insecticides alpha-cypermethrin and cypermethrin have been used for many years to provide protection for young trees planted on restock sites from damage by the large pine weevil, Hylobius abietis L. However, concerns over the toxicity of these insecticides to aquatic life if misused have led to a search for alternative forms of protection. This paper describes a detailed programme of efficacy experiments undertaken between 2009 and 2015 to find replacements for these products. Over 50 combinations of chemical and non-chemical approaches were tested on 16 different sites. Of the alternative synthetic insecticides tested, applications of 0.037 g a.i. stem−1 acetamiprid provided high levels of protection from Hylobius browsing damage on young Sitka spruce (Picea sitchensis (Bong.) Carrière) trees, without causing any phytotoxic symptoms, and gave comparable levels of protection to those achievable using alpha-cypermethrin or cypermethrin. Acetamiprid is less toxic to aquatic life than alpha-cypermethrin or cypermethrin and has not been linked to bee decline. Applications of 0.0129 g a.i. stem−1 chlorantraniliprole also showed promise, and this relatively low toxicity non-neonicotinoid insecticide merits further study. Although imidacloprid and thiacloprid also provided good levels of protection, their use in forests is not now permitted due to concerns over their potential impacts on bees and drinking water, respectively. Whilst the natural product insecticide spinosad, and the entomopathogenic fungal control agent Metarhizium anisopliae (Metschn.) Sorokin, gave only limited protection in our work, they may have some future potential if methods of deployment can be improved. Other chemical and non-chemical approaches tested, but found to be largely ineffective in UK conditions, included the natural product insecticides azadirachtin, maltodextrin and pyrethrins, the synthetic insecticides lambda-cyhalothrin and spirotetramat and a wide range of repellents, flexible stem coatings and physical barrier products. However, we conclude that physical barrier sleeves such as MultiPro® and BioSleeve® may have a limited role as a partial substitute for the use of insecticides in the UK in some circumstances, but only if on-site populations of Hylobius are predicted to be low.

Broad consent for biobanks is best \u2013 provided it is also deep

BackgroundAs biobank research has become increasingly widespread within biomedical research, study-specific consent to each study, a model derived from research involving traditional interventions on human subjects, has for the sake of feasibility gradually given way to alternative consent models which do not require consent for every new study. Besides broad consent these models include tiered, dynamic, and meta-consent. However, critics have pointed out that it is normally not known at the time of enrolment in what ways samples deposited in a biobank may be used in future research and that, for a consent to be informed, exactly this kind of knowledge is required. Therefore, there is an ongoing debate about the ethical acceptability of going for less than study-specific consent.Main textIn light of this debate we address the question of how to best protect participants against relevant risks and violations of autonomy. We apply the central aims of the informed consent process to the unique circumstances of biobank research where samples and data in many cases are stored for long periods of time and reused in subsequent studies. Thereby we are able to formulate a set of criteria focusing both on the risk of informational harm and the potential violation of participants’ values. We compare existing models of consent based on their ability to satisfy the criteria, and we find that the broad consent model offers the best level of protection for participants, although, it suffers from a few important deficiencies with regards to protection against participant value violations and long-term protection of autonomy, if it is applied without qualifications. For this reason, we propose modifications to the current broad consent model, in order to ensure that it provides protection of autonomy and participant values through strong ethical review and continuous communication.ConclusionWe conclude that a modified form of broad consent is ethically superior in biobank research, not only because it is most feasible but primarily because it offers the best available protection against the hazards facing research subjects in this form of research.

Tribocorrosion and corrosion behavior of stainless steel coated with DLC films in ethanol with different concentrations of water

There has been a recent increase in both the production and consumption of ethanol due to the numerous environmental advantages that it offers, such as the fact that it can be produced from a variety of renewable materials, for instance corn and cellulose, or it can be obtained from sugarcane bagasse and biomass (2nd and 3rd generation ethanol). The result of this is that nowadays ethanol is widely seen as the dominant biofuel – or as a blend component in gasoline or pure fuel - in many countries.However, one disadvantage of the use of ethanol is the high corrosive behavior that occurs when its hygroscopic properties are exposed to a large number of materials. Xiaoyuan Lou and Preet Singh showed that the increase of water concentration in ethanol induces pitting and metal loss. Diamond-Like Carbon (DLC) films may be a solution to this problem due to the fact that they can be deposited inside tubes, offer good protection levels against corrosion, and reduce the friction coefficient and wear.This paper shows the tribocorrosion and corrosion studies of DLC films deposited on stainless steel grade 304 (SS304) substrates in order to gauge its appropriateness usage in the construction of pipelines and fuel storage tanks. The surface morphology was analyzed before and after 14 days of immersion. The tribocorrosion, friction coefficient, and wear rate were studied in ethanol to see the effects of water concentration. The films showed good adherence to the substrates. Corrosion and tribocorrosion results showed that for bare Stainless Steel 304 the increase of the water content increases the corrosion and the friction coefficient. DLC coated samples presented few points of delamination, and the friction coefficient and open circuit potentials were very low compared with the bare sample which was water concentration independent.
