In this paper, we dealt with the way of constructing the character of the main character of the novel Iron Gate by the Greek post-war writer Andreas Frangias. The characteristic of his novels is the ...absence of clearly separated main characters, but in the novel Iron Gate, the Angelos link can be considered the main one from the aspect of the influence it has on the other characters of the novel. The aim of the paper is to analyze the procedure used by the writer to build the character of Angelos. The theoretical framework for the analysis is represented by Shlomit Rimon-Kenan's model, which includes direct definition and different ways of indirect representation in the construction of literary characters. Character indicators represented in indirect representation contribute to the synthesis of the character both by their presence in the text, but also by their absence from the text. The analysis showed that indirect representation through action and speech is dominant, but the use of description of external appearance, environment, as well as direct definition is also represented. The conclusion is that the author uses all character indicators from the Rimon-Kenan model to build the main character.
This book analyses the way that changes in the comics industry, book trade and webcomics distribution have shaped the publication of long-form comics. The US Graphic Novel pays particular attention ...to how the concept of the graphic novel developed through the twentieth century. Art historians, journalists, and reviewers debated whether it was possible for a comic to be a novel – debates that accelerated after the term ’graphic novel’ was coined by the comics fan Richard Kyle in 1964. This study underlines the proximity of the graphic novel to other media, showing that this cultural form is not only the meeting place between periodical comics and books, but that graphic novels are in dialogue with films, posters and computer screens.
Monitoring programs are preferably risk-based, which allows focusing on the most relevant human health risks. In this study, a risk matrix was used to identify those chemical hazards that have the ...highest human health risk for the following spices and herbs: paprika/chilli powder, black pepper, nutmeg, basil, thyme, and parsley. Both the probability of occurrence and the severity of the hazard were assessed for 36 chemical compounds and classified into low, medium, high, and severe. Probability of occurrence was evaluated based on available monitoring data and RASFF notifications as well as possibilities for economic adulteration. Severity was assessed based on available toxicological reference values and classification of carcinogenicity. The results demonstrated that the mycotoxins aflatoxins and ochratoxin A, the pesticides chlorpyrifos and triazophos, and the dye Sudan I posed the highest human health risk for spices and herbs. These compounds should, therefore, have an increased monitoring frequency in these products.
•Chemical hazards in spices and herbs were ranked using a risk matrix.•Both the probability of occurrence and the severity of the hazard were scored.•Aflatoxins, ochratoxin A, chlorpyrifos, triazophos and Sudan I were most relevant.
Ellen Glasgow’s works have received, over time, a mixed interpretation,
from sentimental and conventional, to rebellious and insightful. Her novel
In This Our Life (1941) allows the reader to have a ...glimpse of the early
twentieth-century South, changed by the industrial revolution, desperately
clinging to dead codes, despairing and struggling to survive. The South is
reflected through the problems of a family, its sentimentality and
vulnerability, but also its cruelty, pretensions, masks and selfishness,
trying to find happiness and meaning in a world of traditions and codes
that seem powerless in the face of progress. The novel, apparently simple
and reduced in scope, offers, in fact, a deep insight into various issues,
from complicated family relationships, gender pressures, racial inequality
to psychological dilemmas, frustration or utter despair. The article’s aim is
to depict, through this novel, one facet of the American South, the
“aristocratic” South of belles and cavaliers, an illusory representation
indeed, but so deeply rooted in the world’s imagination. Ellen Glasgow is
one of the best choices in this direction: an aristocratic woman but also a
keen and profound writer, and, most of all, a writer who loved the South
deeply, even if she exposed its flaws.
The Leguminosae has emerged as a model for studying angiosperm plastome evolution because of its striking diversity of structural rearrangements and sequence variation. However, most of what is known ...about legume plastomes comes from few genera representing a subset of lineages in subfamily Papilionoideae. We investigate plastome evolution in subfamily Mimosoideae based on two newly sequenced plastomes (Inga and Leucaena) and two recently published plastomes (Acacia and Prosopis), and discuss the results in the context of other legume and rosid plastid genomes. Mimosoid plastomes have a typical angiosperm gene content and general organization as well as a generally slow rate of protein coding gene evolution, but they are the largest known among legumes. The increased length results from tandem repeat expansions and an unusual 13 kb IR-SSC boundary shift in Acacia and Inga. Mimosoid plastomes harbor additional interesting features, including loss of clpP intron1 in Inga, accelerated rates of evolution in clpP for Acacia and Inga, and dN/dS ratios consistent with neutral and positive selection for several genes. These new plastomes and results provide important resources for legume comparative genomics, plant breeding, and plastid genetic engineering, while shedding further light on the complexity of plastome evolution in legumes and angiosperms.
The European Commission asked EFSA for a scientific evaluation on the risks to human health related to the presence of perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) in food. ...Regarding PFOS and PFOA occurrence, the final data set available for dietary exposure assessment contained a total of 20,019 analytical results (PFOS n = 10,191 and PFOA n = 9,828). There were large differences between upper and lower bound exposure due to analytical methods with insufficient sensitivity. The CONTAM Panel considered the lower bound estimates to be closer to true exposure levels. Important contributors to the lower bound mean chronic exposure were ‘Fish and other seafood’, ‘Meat and meat products’ and ‘Eggs and egg products’, for PFOS, and ‘Milk and dairy products’, ‘Drinking water’ and ‘Fish and other seafood’ for PFOA. PFOS and PFOA are readily absorbed in the gastrointestinal tract, excreted in urine and faeces, and do not undergo metabolism. Estimated human half‐lives for PFOS and PFOA are about 5 years and 2–4 years, respectively. The derivation of a health‐based guidance value was based on human epidemiological studies. For PFOS, the increase in serum total cholesterol in adults, and the decrease in antibody response at vaccination in children were identified as the critical effects. For PFOA, the increase in serum total cholesterol was the critical effect. Also reduced birth weight (for both compounds) and increased prevalence of high serum levels of the liver enzyme alanine aminotransferase (ALT) (for PFOA) were considered. After benchmark modelling of serum levels of PFOS and PFOA, and estimating the corresponding daily intakes, the CONTAM Panel established a tolerable weekly intake (TWI) of 13 ng/kg body weight (bw) per week for PFOS and 6 ng/kg bw per week for PFOA. For both compounds, exposure of a considerable proportion of the population exceeds the proposed TWIs.
Insects have potential as a novel source of protein in feed and food production in Europe, provided they can be used safely. To date, limited information is available on the safety of insects, and ...toxic elements are one of the potential hazards of concern. Therefore, we aimed to investigate the potential accumulation of cadmium, lead and arsenic in larvae of two insect species, Tenebrio molitor (yellow mealworm) and Hermetia illucens (black soldier fly), which seem to hold potential as a source of food or feed. An experiment was designed with 14 treatments, each in triplicate, per insect species. Twelve treatments used feed that was spiked with cadmium, lead or arsenic at 0.5, 1 and 2 times the respective maximum allowable levels (ML) in complete feed, as established by the European Commission (EC). Two of the 14 treatments consisted of controls, using non-spiked feed. All insects per container (replicate) were harvested when the first larva in that container had completed its larval stage. Development time, survival rates and fresh weights were similar over all treatments, except for development time and total live weight of the half of the maximum limit treatment for cadmium of the black soldier fly. Bioaccumulation (bioaccumulation factor > 1) was seen in all treatments (including two controls) for lead and cadmium in black soldier fly larvae, and for the three arsenic treatments in the yellow mealworm larvae. In the three cadmium treatments, concentrations of cadmium in black soldier fly larvae are higher than the current EC maximum limit for feed materials. The same was seen for the 1.0 and 2.0 ML treatments of arsenic in the yellow mealworm larvae. From this study, it can be concluded that if insects are used as feed materials, the maximum limits of these elements in complete feed should be revised per insect species.

Nanotechnology has the potential to innovate the agricultural, feed and food sectors (hereinafter referred to as agri/feed/food). Applications that are marketed already include nano-encapsulated ...agrochemicals or nutrients, antimicrobial nanoparticles and active and intelligent food packaging. Many nano-enabled products are currently under research and development, and may enter the market in the near future. As for any other regulated product, applicants applying for market approval have to demonstrate the safe use of such new products without posing undue safety risks to the consumer and the environment. Several countries all over the world have been active in examining the appropriateness of their regulatory frameworks for dealing with nanotechnologies. As a consequence of this, different approaches have been taken in regulating nano-based products in agri/feed/food. The EU, along with Switzerland, were identified to be the only world region where nano-specific provisions have been incorporated in existing legislation, while in other regions nanomaterials are regulated more implicitly by mainly building on guidance for industry. This paper presents an overview and discusses the state of the art of different regulatory measures for nanomaterials in agri/feed/food, including legislation and guidance for safety assessment in EU and non-EU countries.
•Nanotechnology applications in the agri/feed/food sector are growing worldwide.•Different approaches are applied to regulate nanotechnology applications.•The EU has binding NM definitions and NM-specific provision for some applications.•Several non-EU countries regulate NM by mainly building on guidance.
The European Commission asked EFSA for a scientific opinion on the risks for animal and human health related to the presence of dioxins (PCDD/Fs) and DL‐PCBs in feed and food. The data from ...experimental animal and epidemiological studies were reviewed and it was decided to base the human risk assessment on effects observed in humans and to use animal data as supportive evidence. The critical effect was on semen quality, following pre‐ and postnatal exposure. The critical study showed a NOAEL of 7.0 pg WHO2005‐TEQ/g fat in blood sampled at age 9 years based on PCDD/F‐TEQs. No association was observed when including DL‐PCB‐TEQs. Using toxicokinetic modelling and taking into account the exposure from breastfeeding and a twofold higher intake during childhood, it was estimated that daily exposure in adolescents and adults should be below 0.25 pg TEQ/kg bw/day. The CONTAM Panel established a TWI of 2 pg TEQ/kg bw/week. With occurrence and consumption data from European countries, the mean and P95 intake of total TEQ by Adolescents, Adults, Elderly and Very Elderly varied between, respectively, 2.1 to 10.5, and 5.3 to 30.4 pg TEQ/kg bw/week, implying a considerable exceedance of the TWI. Toddlers and Other Children showed a higher exposure than older age groups, but this was accounted for when deriving the TWI. Exposure to PCDD/F‐TEQ only was on average 2.4‐ and 2.7‐fold lower for mean and P95 exposure than for total TEQ. PCDD/Fs and DL‐PCBs are transferred to milk and eggs, and accumulate in fatty tissues and liver. Transfer rates and bioconcentration factors were identified for various species. The CONTAM Panel was not able to identify reference values in most farm and companion animals with the exception of NOAELs for mink, chicken and some fish species. The estimated exposure from feed for these species does not imply a risk.
