Activated carbons (ACs) have been prepared from chemical treatment of walnut shells (WS) precursor at various temperatures (400‒800 °C) by using phosphoric acid (H3PO4) as activating agent. Influence of activation temperature on the porosity development and capacitive properties of resulting carbons was investigated. Thermal post-treatment of carbons previously activated at moderate temperature, e.g. 400 °C allowed further structural and porosity modification. Then, these carbons were investigated by scanning electron microscopy, Raman spectroscopy, energy-dispersive X-ray spectroscopy, electrochemical techniques and low temperature nitrogen adsorption exhibiting high BET specific surface area of approximately 2100 m2 g-1 and a total pore volume up to 1.3 cm3 g-1. Carbon material obtained through activation by H3PO4 at 400 °C and post-treated at 800 °C was used to make electrodes which were implemented to realize AC/AC capacitor using 1 mol L-1 Li2SO4. The electrochemical capacitor demonstrated high capacitance of 123 F g-1 per mass of one electrode, reduced cell resistance and stable capacitance for 5000 galvanostatic charge/discharge cycles at 1.0 A g-1.
Impact of former long-term fertilization on springtail communities in a reforested experimental area
Authors: Harta István , Winkler Dániel , Füleky György
Published: July 2018

At the beginning of the 1970’s, two fertilization experimental areas were established in Gödöllő. After different long-term fertilization treatments, sessile oak (Quercus petraea) and black locust (Robinia pseudoacacia) plantations were planted in the second half of the 1990’s. In the present research, the effects of former fertilization were studied in these two different forests, with the help of soil Collembola communities as indicators. Soil cores and litter samples were collected from the chosen 30 plots to determine the most important soil parameters and to extract Collembola specimens. According to the results, soil organic carbon (SOC), AL-P2O5 and AL-K2O contents were significantly higher in the two highest-dose treatments of the sessile oak plantation compared to the control. In the black locust plantation, only AL-P2O5 content differed significantly in the second highest-dose treatment when compared to the control. Among the two plantations significant differences can be observed in almost every parameter, except for AL-K2O and nitrogen content. The effects of former fertilizer application are reflected in occasional differences in total Collembola abundance, species richness and diversity, mostly related to the treatments with the highest doses. Due to the relatively young age of the plantations, very few typical forest Collembola species were observed, while species characteristic for open habitats are still predominant. The higher SOC content in the black locust plots is well reflected in the higher Collembola abundance compared to the sessile oak plots. Nevertheless, species richness, diversity and equitability were higher in the plantations of the native sessile oak.

Published: July 2018

These days, increasing attention has been paid to understand the relationship between different farming systems and soil microbiological processes supporting sustainable land use. Soil microbiota have been considered as a priority component in organic land managements and sustaining soil health in long term. This statement should be supported by appropriately selected indicators - physiological properties or more precisely the metabolic activity profile of the soil microbes. A recently developed method, MicroRespTM gives a promising characterization of the catabolic activity pattern of the soil microbial communities. The goal of this study was to compare the catabolic profile of soil microbial communities of organic and conventional land management in a long-term experiment at Martonvásár (Hungary) from two consecutive years by two samplings (autumn and spring). MicroRespTM with 22 different substrates were used to characterize the catabolic activity patterns of these soils. Multivariate statistical analysis revealed a significant difference between the catabolic activity profiles of the soil microbial communities of the two management systems. Considering the soil chemical parameters, the AL-P2O5-K2O, NO3--N were responsible for the divergence of the two farming systems according to the principal component analysis (PCA). The biotic (crop) and abiotic (EC, humus content, pH) parameters could affect not only the rate of soil respiration but the catabolic activity profiles as well. Organic farming increased the catabolic activity of soil microbes.

Authors: Bakonyi István , Csitári Gábor
Published: July 2018

The effect of arbuscular mycorrhizal (AM) fungi inoculation was investigated on two winter wheat cultivars (Triticum aestivum var. Mv Nádor and var. Genius) grown under farm conditions in the neighbourhood of Nagyhörcsök in 2016. The soil was a chernozem with lime deposits (WBR classification: Calcic chernozem) with a mean humus content of 2.73%, AL-soluble P2O5 and K2O concentrations of 181 mg kg-1 and 149 mg kg-1 and a pH(KCl) value of 7.27. The AM inoculum contained reproductive units of Rhizophagus irregularis (previously Glomus intraradices) and Glomus mosseae (syn. Funneliformis mosseae). In addition to soil inoculation, some of the treatments were also given mineral fertiliser treatment (130 kg N ha-1, 78 kg P2O5 ha-1, 60 kg K2O ha-1). Both AM inoculation and mineral fertiliser treatment were found to have a significant effect on the yield (at the p<0.05 level). The yield of plots with mycorrhizal inoculation averaged 8.17 t ha-1, which was higher than that of non-inoculated plots (7.52 t ha-1), while the yield of plots with fertiliser treatment averaged 8.31 t ha-1, as compared with 7.38 t ha-1 for non-fertilised plots. The yield-enhancing effect of AM inoculation was only manifested in plots given no mineral fertiliser. Plant protection measures were the same in all the treatments. The results and the conclusions drawn from them were based on the data of a single year (2016). Data from experiments performed in several years with more cultivars and soils with diverse properties will be required to obtain better grounded, more reliable recommendations for farmers.
Sharing Economy Startups: New Wave of Networked Business Models in the Changing World
Authors: Toivola Tuija
Published: July 2018

The relatively new phenomenon called sharing economy, or collaborative consumption, is best known by the companies like Airbnb and Uber. These companies use mobile applications and web platforms to match people willing to share a room or a car with others who need a ride or a place to stay. The peer-to-peer economy has disrupted traditional business models and upset the regulatory status quo (Shueh, 2014). Sharing economy has challenged mature industries, such as hotels, restaurants, cars, by providing consumers with convenient and effective access to resources without the financial, emotional or social burdens of ownership. In that sense, sharing economy is also an access economy (Eckhardt & Bardhi, 2015). There is a whole bunch of new startups springing up and joining the sharing economy movement. Companies are inventing new ways of integrating customers in their value creation processes in order to enhance the success of new service concepts. In this study, sharing economy is defined as a set of practices and business models based on horizontal networks and the participation of a community (Ouishare; Ismail, 2014). The aim of this study is to increase understanding of how the new networked startups operate and how they create value for their customers. We especially look at the role of platforms, the innovations in organizing the business and the role of the networks and communities. The data is collected from a Finnish sharing economy startup operating in the restaurant industry (lunch leftovers). The early stage startups’ business model is compared to the leading startups in the sharing economy. The data is collected by interviewing the entrepreneurs, drawing the customer journeys and visualizing the elements of their business models. A case study is used as a method because the study aims to explain what kind of business models sharing economy startups use and what is the role of the different elements in their success in partnerships, resources, customer relationships, and communities. A Case study is relevant when the study requires an extensive and in-depth description of the phenomenon (Yin, 2014). As a result, this study will provide insight into how the new sharing economy startups organize their businesses to create unique value for the customers. This article will contribute to the increasing interest of enhancing customer experience and raise some key elements for the success factors of the sharing economy. Also, the study will highlight the possibilities of digital platforms enhancing the growth and internationalization of startups.

Published: July 2018

A six-week trial was conducted to determine the effect of lowering dietary crude protein levels with supplementation of limiting amino acid on growth performance, and carcass characteristics in one of the Indian improved crossbred Swarnadhara chicks in a completely randomized design having five treatments and four replications of 20 birds in each. Five isocaloric (2800 ME Kcal//kg) experimental diets based on corn-soy bean meal were formulated in a gradual crude protein decline from 21 % (control T1) to 19% by 0.5% interval. The levels of limiting amino acids namely methionine, lysine, threonine and tryptophan were met as that of control (T1) by adding synthetic preparations. Highest body weight was recorded in 2% crude protein reduced group (T5) which was comparable with control (T1). However, cumulative feed intake and feed conversion ratio of different treatments were not significantly different. Moreover, carcass parameters like dressing percentage, breast meat yield, liver and heart weights remained unaffected by the dietary treatments. Relative gizzard weight and abdominal fat weights showed variations and lower dietary protein diets were comparable with control diet (T1). In summary, crude protein content of Swarnadhara chick diet can be reduced to 19% with essential AA fortification without any adverse effect on growth performance and carcass characteristics during 0-6 weeks of age.

The objective of present study was to investigate the effects of two different levels of dissolved oxygen (DO) i.e. 4 and 8 ppm in the extenders on physico-morphological attributes and functional membrane integrity of crossbred bull spermatozoa following cryopreservation. Only those ejaculates that had a mass activity of ³ 3+ and individual progressive motility of ³ 70% were utilized. Each of the ejaculates were divided and extended to have 80×106 spermatozoa/ mL of extender in three groups i.e. Group I (control), Group II (4 ppm) and Group III (8 ppm). Progressive motility (%) was higher (p Lass Than 0.05) in Group II and III as compared to Group I at both pre-freeze and post-thaw stage. Per cent live sperm and HOST reactive sperm were higher (p Lass Than 0.05) in Group II and in Group II and III as compared to Group I at pre-freeze and post-thaw stage, respectively. Sperm abnormality (%) was lower (p Lass Than 0.05) in Group II at post-thaw stage. Per cent acrosome intact sperm did not differ (p>0.05) among the groups at pre-freeze stage, but, were higher (p Lass Than 0.05) in Group II and III as compared to Group I at post-thaw stage. In conclusion, cryopreservation of semen having DO level of 4 ppm in semen extender yielded better results followed by 8 ppm in terms of semen quality parameters and functional membrane integrity of crossbred bull spermatozoa.

Published: July 2018

The lysine is considered as the most important essential amino acid, because it is the most limiting in the cereals grains. In this study, a lysine-rich (LR) gene, and the expression vector pcDNA3.1-LR and pBC1-LR were constructed. The LR was expressed in 293T cells driven by the vector pcDNA3.1-LR and checked by RT-PCR and WB. The mammary gland tissue-specific expression vector carrying the LR was injected directly into the lactating mammary glands of cows and the milk samples were checked by a complete amino acid analysis. The results showed that the LR protein was expressed successfully in cells and in cow milk; the expression of LR lasted for 6 d, and the lysine level of the injection group was significantly higher than that of negative controls (p Lass Than 0.05). This study provide a better understanding of how mammary gland expression systems increase the lysine content of milk that can be applied to transgenic dairy cow.

Published: July 2018

Field experiments were carried out at Faculty of Agriculture and Natural Resource Management, Ebonyi State University, Abakaliki in 2011 and 2012 dry seasons to study the effect of water stress at different phenological stages of muskmelon. Results revealed that watering intervals of every six days significantly influenced number of leaves, number of branches and days to 50% flowering.During flowering phase, the plots that were watered in every six and nine days flowered late while early flowering were recorded by plots that were watered once a day and every three days. The higest yield of muskmelon was observed in irrigation intervals of six days.Also watering frequency of six days intervals had maximum net income, closely followed by nine days intervals. It can be inferred that watering frequency of every six days intervals significantly affected both growth and yield characters of the crop studied at different phenological stages and it could be recommended for growing the crop in the study area.

Sylviculture tropicale en forêt dense africaine (partie 2)
Authors: Catinot René
Published: July 2018

Dans la deuxième partie de l’article, l’auteur expose les méthodes sylvicoles employées dans la forêt dense d’Afrique à l’aide d’une régénération artificielle. La méthode « Taunguya » n’est pas très répandue dans les zones forestières. La méthode « Limba », employée au Congo, sert à établir une plantation de stumps (souches de jeunes plants) de limba (Terminalia superba) à intervalles de 6 à 9 m ou 12 à 14 m dans une forêt naturelle complètement détruite. Avec la méthode « Okoumé », utilisée au Gabon sur 16 000 ha, les arbres sont plantés à intervalles de 4 à 5 m par semis direct ou plantation de jeunes plants, ou après déforestation. La méthode « Martineau », utilisée en Côte d’Ivoire dans les années 1930, implique une plantation serrée (2 500 très jeunes plants par hectare) en forêt naturelle, avec une ouverture progressive lente de la canopée. La méthode des « Layons » est très extensive, et produit un enrichissement des peuplements par l’introduction de jeunes plants dans les layons par éclaircies de la forêt naturelle à 25 m d’intervalle (13 000 ha en Côte d’Ivoire). La méthode des « Placeaux » introduit de jeunes plants très serrés dans des carrés de forêt naturelle. Les arbustes concurrents et les arbres de la canopée sont progressivement et lentement éliminés.
Variation in Macrophage Phagocytosis of Streptococcus agalactiae Does Not Reflect Bacterial Capsular Serotype, Multilocus Sequence Type or Association with Invasive Infection
Authors: Rogers Lisa M. , Gaddy Jennifer A. , Manning Shannon D. , Aronoff David M.
Published: July 2018

Background: Group B Streptococcus(GBS) is an encapsulated Gram-positive coccus that is an important cause of infections in adults with chronic medical conditions, pregnant women, and neonates. GBS causes a range of clinical syndromes, from asymptomatic colonization to deep-seated invasive and highly lethal infections. Macrophages are important sentinels of innate immunity, protecting host tissues from infection when bacteria advance beyond cutaneous or mucosal barriers. We hypothesized that the capacity for macrophages to phagocytose unopsonized GBS would vary across distinct clinical strains, and such differences would reflect serotype diversity.Methods: A high-throughput screen using the phorbol ester-differentiated THP-1 macrophage-like human cell line was used to quantify phagocytosis of a diverse group of 35 different human clinical isolates of GBS representing a wide variety of capsular serotypes. Validation studies were conducted using human primary phagocytes.Results: Phagocytosis of GBS differed widely across clinical isolates but this was not related to capsular serotype, genetic sequence type, pilus type, or clinical source of the GBS isolate (colonizing or invasive strain).Conclusions: Structural and/or biochemical differences among diverse GBS strains are reflected in a diverse capacity for macrophages to ingest them through non-opsonic phagocytosis. Mechanisms explaining these differences are not clear.Keywords: Neonatal sepsis; innate immunity; macrophages; Gram-positive bacteria; diabetes
Sex Differences in HIV Infection: Mystique Versus Machismo
Authors: Scully Eileen P.
Published: July 2018

Biological sex is a determinant of both susceptibility to and pathogenesis of multiple infections, including HIV. These differences have effects on the spectrum of HIV disease from acquisition to eradication, with diverse mechanisms including distinct chromosomal complements, variation in microbiota composition, hormonal effects on transcriptional profiles, and expression of different immunoregulatory elements. With a comparative biology approach, these sex differences can be used to highlight protective and detrimental immune activation pathways, to identify strategies for effective prevention, treatment, and curative interventions.

Objetivos: Establecer las relaciones entre la acción moral de la enfermera(o) con el arte del cuidado de modo que se identifiquen los significados que se le asignan en la praxis. Material y método: se realizó una revisión literaria en las bases de datos: SciELO, PubMed, RedALyC, BiDi-UNAM, se utilizaron los descriptores: ética, moral, cuidado y arte del cuidado; además de bibliografía sobre el cuidado y la ética del cuidar, la base de datos se constituyó de 60 artículos y 6 libros en un periodo de 1990 a 2016 en su mayoría artículos de investigación y ensayos; el análisis de la información se ubica en la perspectiva fenomenológica-hermenéutica. Resultados: Se identificaron tres tipos de significados: El éthos de enfermería, los constructos éticos del cuidar y la acción moral en el arte del cuidado. Conclusión: El ethos de enfermería es el espacio-tiempo en donde se construye el arte del cuidado a través del ejercicio de una práctica moral aceptada por la persona cuidada, se sustenta en una axiología, ética y estética vitalista, que influencia su ser como praxis trascendente en el cuidado del otro. Los constructos éticos del cuidado es la obligación que los profesionales de enfermería se imponen así mismos desde una perspectiva ética que promueve la reflexión subjetiva particular; en síntesis, es el cuidar en sí. La acción moral en el arte del cuidado fortalece la importancia de la aplicación del conocimiento en la práctica, como creación de cultura y arte, a partir de la interacción enfermera (ro) persona en un proceso de alteridad.

Starting with some experimental observations published by our laboratories and others, we develop some predictions regarding cellular oxidant stress.
Care, Indifference and Anxiety—Attitudes toward Location Data in Everyday Life
Authors: Rzeszewski Michal , Luczys Piotr
Published: July 2018

Modern mobile devices are replete advanced sensors that expand the array of possible methods of locating users. This is often viewed in a positive light, as a tool to gather and use spatial information, but it also brings with it the problem of “geosurveillance” in which the “Location” becomes a product in itself. In the realm of software developers, this has been reduced and discretized to a set of coordinates, devoid of human experiences and meanings. To function in such digitally augmented realities, people need to adopt specific attitudes, often accompanied with anxiety. We explored attitudes toward locational data collection practices using questionnaire surveys (n = 280) from Poznan and Edinburgh. The prevailing attitude is neutral with a strong undertone of resignation, in which surrendering personal locational information is viewed as a digital currency. A smaller number of people had stronger, emotional views, either very positive or very negative, based on uncritical technological enthusiasm or fear of privacy violation. Such a wide spectrum of attitudes is not only produced by interaction with technology but can also be viewed as a result of different perceptions and values associated with space and place itself.

Novel high energy density materials N14 (1,6-dihydro-1,2,3,3a,4,5,5a,6,7,8,8a,9,10,10a-tetradecazapyrene) and N18 (1,2,2a,3,4,4a,5,6,6a,7,8,8a,9,10,10a,11,12a-octadecazacoronene) were designed, and their structures, detonation performance and stabilities were calculated employing density functional theory (DFT). Calculations reveals that they have a good balance between high energy and stability. Their energy gaps between LUMO and HOMO are all lower than that of TATB, while their impact sensitivity h50% is estimated close to that of RDX. Concerning energy, detonation performance of the N14 (P = 43.6 GPa, D = 10040 m/s, Q = 2214 cal/g) and the N18 (P = 37.4 GPa, D = 9400 m/s, Q = 2114 cal/g) are comparable to CL-20.

Published: July 2018

Aiming at the problems that large amount of video monitoring image data in underground coal mines leads to difficulties in transmission and storage, compressed sensing theory is introduced to encode and decode video images, and a new distributed video coding scheme is proposed. In order to obtain more sparse representation and more general applicability, a block-based adaptive sparse base scheme is proposed. For the acquisition of side information, fixed weight is usually used to synthesize side information and the correlation between different image blocks is neglected, a block-based classification weighted side information generation scheme is proposed. Experimental results show that the block-based classification codec scheme can make full use of inter-frame correlation. Under the appropriate sampling rate, the PSNR value of video reconstruction increases, which effectively improves the quality of video frame reconstruction.
Characterization of Keratinophilic Fungal Species and Other Non-Dermatophytes in Riyadh, Saudi Arabia
Authors: Alwakeel Suaad
Published: July 2018

Background: The presence of fungal species on the surface skin and hair is a known finding in many mammalian species and humans are no exception. Superficial fungal infections are sometimes a chronic and recurring condition that affects approximately 10-20% of the world’s population. However, most species that are isolated from humans tend to occur as co-existing flora. This study was conducted to determine the diversity of fungal species isolated from the hair and nails of workers in the central region of Saudi Arabia where there are not many observational studies on the mycological species. Materials and Methods: Male workers from Riyadh, Saudi Arabia were recruited for this study and samples were obtained from their nails and hair for mycological analysis which was done using Saboraud’s agar and sterile wet soil. Fungal isolates were examined microscopically. Results: Twenty four hair samples yielded a total of 26 species from 19 fungal genera. Chaetomiumglobosum was the most commonly isolated fungal species followed by Emericellanidulans, Cochliobolusneergaardii, and Penicilliumoxalicum. Three fungal species were isolated from nail samples, namely, Alternariaalternata, Aureobasidiumpullulans, and Penicilliumchrysogenum. Most of the isolated fungal species (17 of the 26 or 65.38% of the isolated fungal species) have not been thoroughly characterised nor morphologically classified. Conclusion: This study demonstrates the presence of previously undescribed fungal species that contribute to the normal flora of the skin and its appendages and may have a role in their pathogenies.

Authors: Park Joo Myun , Huh Sung-Hoi
Published: July 2018

The dietary patterns of the glowbelly Acropoma japonicum Gunther, 1859 were studied based on 180 specimens collected during January to December 2006 off the south-eastern coast of Korea. The standard length (SL) of the specimens ranged from 3.0 to 10.3 cm. A. japonicum was found to be a benthopelagic predator that primarily consumed copepods and carid shrimps, but also preyed moderately on teleosts and euphausiids. The dietary composition of A. japonicum differed between length classes, with copepods and carid shrimps being dominant in the diet of small and large length class, respectively. The diets also were different among seasons, with the difference particularly being evident between warm (summer and autumn) and cold (winter and spring) seasons. Permutational multivariate analysis of variance (PERMANOVA) and analysis of similarities (ANOSIM) revealed significant dietary differences by size and season. These differences in the diets were related to first maturity in female and seasonal changes in water temperature.

Stigmatogobius pleurostigma (Bleeker, 1849) is an estuarine species of goby and widely distributed in Asian regions, but very little is known about the reproductive biological traits of this species. The present study was conducted along the coastline of the Mekong Delta, Vietnam from November 2015 to October 2016 to elucidate basic reproductive parameters of the species. A total of 155 fish (96 females and 59 males) were collected every month using fixed bag nets from the mangrove forests in the study area. Data analysis showed that the sex ratio is significantly different from 1:1. This gobiid species is an iteroparous fish spawning from March to November in the study region as deduced from the appearance of mature and ripe ovaries during this period. The length at first maturity was estimated as 4.14 cm in total length and absolute fecundity was found to be quite high (3,100-5,650 eggs) with a strong positive relationship with fish length and weight. The results obtained in this study contribute to the knowledge on the reproductive biology as well as stock status of the species.

An experiment of 65 days duration was conducted to study the effect of biofilm formed on different natural substrates at different substratum densities on the growth and survival of juveniles of freshwater prawn Macrobrachium rosenbergii (de Man, 1879). Natural substrates like dried paddy straw and cut grass were evaluated as substratum for biofilm production. The experiment was conducted in fiber glass tanks of 500 l capacity. The study comprised six treatments viz., dried paddy straw at 60 (T1); 120 (T2) and 240 (T3) g tank-1 and cut grass at 60 (T4) and 120 (T5) g tank-1, each with three replicates following a completely randomised design. Prawn juveniles reared without any substratum acted as control. Ten days after the introduction of substratum in the tanks, prawn juveniles (2.01 g±0.37) were stocked at a density of 40 m-³. The juveniles were fed with 2 mm commercial pellet feed (30% protein) at 5% of the biomass. No water exchange was done in the treatment tanks whereas in control tanks 50% water exchange was done once every week. The study revealed significantly (p<0.05) higher survival rate (%) in the treatment tanks (94.4±9.6, 80.5±12.7, 86.1±12.7, 86.1±4.8 and 91.6±8.35 for treatments T1, T2, T3, T4 and T5 respectively) compared to the control (52.8±9.5). Among treatment tanks, T2 and T3 showed significantly higher (p<0.05) average daily growth (g d-1) (0.055±0.005 and 0.057±0.005 respectively) when compared to other treatments (0.0367±0.02 for T1 and 0.0373±0.01 for T5). But the specific growth rate did not show any significant difference among the treated groups including control. Use of biofilm significantly reduced the usage of water (by 2.9 times) compared to control, which is significant considering the predicted water scarcity in future.

Published: July 2018

Intussusception is a rare condition in fish, mainly reported from Asian countries and it is considered an emergent disease in China. This is the first report on intussusception case in channel catfish Ictalurus punctatus, cultured in floating cages in Mexico. Fishes were sampled during an outbreak with daily mortalities above 1.14%. Necropsy revealed intestinal intussusception, pale liver and hemorrhagic mesentery. Bacteriological analyses showed presence of Aeromonas sp. in internal organs and it is suggested that the presence of Aeromonas sp. is probably responsible for the observed condition.

Samples of vegetation (vascular plants) were collected at 14 grasslands on Kunashir, Iturup, Urup and Paramushir Islands in August–September 2012. All surveyed grasslands were virgin lands with respect to Fukushima fallout. Four plots were used as pastures for cattle in 2012. About 1 kg of green vegetation (mixed grass-forb crop) was taken from each of 13 plots. Seven samples of wormwood (Artemisia sp.) and three samples of Kuril dwarf bamboo (Sasa sp.) of the same mass were collected for comparison. A density of the above ground biomass was estimated at one of the plots. Activities of134Cs and137Cs radionuclides were determined by direct γ-ray spectrometry method using HP-germanium detectors. Inventories of134Cs and137Cs in the top 20 cm layer of soil were estimated by the authors earlier for each of these 14 plots based of the soil samples analysis. Caesium-134, a marker of Fukushima fallout, was determined in 18 of 24 vegetation samples. Caesium-137 activity was quantified in all of 24 samples. The activity concentration of the radionuclides in plants (wet weight) ranged from <0.05 Bq kg−1to 1.6 Bq kg-1for134Cs and from 0.06 Bq kg−1to 5.8 Bq kg-1for137Cs. About 2/5 (median = 41%, n = 18) of the total activity of137Cs in plants was associated with the Fukushima accident. The soil-to-plant aggregated transfer coefficient (Tag) values in mixed grass-forb crop ranged from <0.2 × 10–3m2kg-1to 11 × 10–3m2kg-1for134Cs and from 0.08 × 10–3m2kg-1to 3.3 × 10–3m2kg-1for137Cs. The Tagvalues for134Cs were statistically significantly higher compared to the Tag values for 137Cs. The median Tagfor134Cs in mixed grass-forb crop decreased in the 2011–2012 period by a factor of about two: from 12 × 10–3m2kg-1to 6.6 × 10–3m2kg-1. The ecological half-time, Teco, of134Cs in the plants was approximately one year. In 2011–2012, the median Tagfor pre-Fukushima137Cs in mixed grass-forb crop was estimated as 0.12 × 10–3m2kg-1. This value is lower by a factor of 100 and 50 compared to the median values of Tagthat were deduced for Fukushima-derived radiocaesium in 2011 and 2012, respectively. The radiocaesium Tagvalues for Sasa sp. and Artemisia sp. agreed with those for mixed grass-forb crop. At grasslands with the aboveground biomass density of 1 kg m–2and the Tagof 6 × 10–3m2kg-1 for134Cs, the contribution of the vegetation contamination to total inventory of the radionuclide did not exceed 1%. For137Cs, this contribution was less than 0.1%.

Published: July 2018

The purpose of the study was to estimate the doses to the Voronezh region population from natural sources of ionizing radiation and the technologically altered background in the territory of Voronezh Region. The data of forms of state statistical observation No. 4-DOZ “Information on the doses of population exposure due to natural and technologically altered background” for 20102017 and the radiation and hygienic passport of the territory of the Voronezh Region were used. The average annual per caput effective dose due to all types of ionizing radiation remains stable with a slight upward trend and lies in the range from 2.925 (2010) to 3.656 mSv (2017). Natural sources are the main dose-forming factors for the population. Their annual contribution to the annual effective dose ranges from 74.96 to 83.65%. The leading contribution to the total dose from natural sources is the exposure due to the inhalation of radon isotopes: it ranges from 37.6 to 51.1%. In second place,there is the share of external exposure from sources of terrigenous origin, which ranges from 21.2 to 28.9% of the total dose. The average annual effective dose of natural exposure to humans varies from 2,355 to 2,980 mSv / year, the exposure from radon – from 0,83 to 1,65 mSv / year. The dose from technogenic-altered radiation background, including global radioactive fallout due to atmospheric nuclear tests and due to past radiation accidents are insignificant (0,062 mSv / year). Its annual contribution to the total dose is less than 2%. Based on the results of the assessment of the indicators characterizing the level of exposure of sources of ionizing radiation to natural and technogenic-altered radiation background, no excess of radiation safety standards has been recorded. The situation associated with exposure to ionizing radiation sources in the Voronezh region has been described as safe for the last 8 years.
