GEOCHEMICAL FEATURES OF POST-PYROGENIC CHANGES OF POLISSYA SOILS (LOW FIRE)

Geochemical post-pyrogenic soil changes are one of the most important factors in determining the state of the forest ecosystem. For the first time the content of microelements (Hg, As, Ba, Mg, Mn, Mo, Cd, Co, Cr, Cu, Pb, Zn, V, Ni) in post-pyrogenic sod-podzolic soils under the pine forest of Zhytomyr Polissya (Ukraine) was determined by the ICP-MS method. The study is based on a comparison of the content of trace elements in the sod-podzolic soils of the background area and burnt areas (grassland fire in 2019). The analysis of microelements in the soil profile of the burned and background areas to a depth of 10 cm (after 1 cm) and set the limit - 3-5 cm (humus-eluvial horizon), after which you can record the accumulation or scattering of elements after a fire on the surface. By calculating the percentage change (relative to background soils), intensive accumulation (more than 20%) of elements in post-pyrogenic soils - Cu, Ni, Co, V and moderate accumulation (up to 10%) - Pb, Mo, Mg, Ba, Cr and intensive scattering - Hg, As, Cd, Zn, Mn. The increase in the pH of post-pyrogenic soils (from 4.2 to 7.5) was determined, spatial map-schemes were constructed, due to which the direction of the fire was revealed - from the south-east to the north-west. The change of the content of ionic forms of metals (Cu, Pb, Zn, Mn) in the soil solution at different pH values (from 4 to 8 with a step of 0.2) is modeled (PHREEQC program) and the current trend is revealed: Pb - linear dependence, Cu, Zn, Mn is polynomial. The pH limits are calculated, where there are free forms of metals that enter the plants: Pb 3.9-8.2; Zn 5.5-7.5; Cu 5-8.2; Mn 5-11.5. The post-fire transformation of soils was revealed, which is expressed in the increase of pH (before the fire - 4.2-4.8; after the fire - 6.5-7.2; a year after the fire - 4.5-5.5). The obtained results confirmed the need for geochemical monitoring of post-pyrogenic soils for ecosystem restoration and plant biodiversity.

As has been shown and extensively dealt with in early and more recent scholarship, Neo-Assyrian palatial wall reliefs went through many thematic changes throughout their two hundred and fifty years of existence. One of their conspicuous traits was a gradual abandoning of magical-religious subject matters, represented by protective supernatural beings, in favour of larger and more detailed historical compositions — mostly of a belligerent nature — revealing, for the first time in antiquity, a truer sense of narrative display. As the narrative-historical themes were rightly considered to be an innovative and prominent contribution of Assyrian imagery to the history of art, extensive efforts have been devoted to the study of these compositions within the context of Assyrian palaces.In the present contribution I intend, however, to concentrate on the “losing” side of Assyrian palatial decoration, namely to focus on the visibility of apotropaic fantastic creatures rendered on wall reliefs and to offer some explanation for their gradual expulsion from the pictorial display of the Assyrian palace. Following Porada, in this essay these hybrids are called demons, in accordance with the Greek term daimon. Benevolent demons appear already in early ninth-century Neo-Assyrian wall reliefs, both in temples, as shown by a small number of slabs from the Ninurta Temple at Nimrud, and much more commonly in palaces, in particular within the North-West Palace.

Intra- and interspecific variation in a 658 bp long part of the cytochrome c oxidase subunit 1 (COI) gene of the mitochondrial genome, i.e. a suggested ‘DNA barcode’, was assessed in four north-west European species of the marine tubificid genus Tubificoides: T. benedii, T. amplivasatus, T. heterochaetus and T. kozloffi. Within species mean genetic distance was from 0.10% (T. amplivasatus) to 0.14% (T. benedii), between species from 19.3% to 22.9%. For T. benedii and T. amplivasatus, material collected in two separate areas, The Sound between Denmark and Sweden, and the Koster area about 330 km to the north along the Swedish west coast, showed a geographically random distribution of COI haplotypes, suggesting that each of these two species forms a continuous population in southern Scandinavia. We conclude that the COI gene is suitable as a barcode marker for the secure identification of these species, at least within the area investigated. Tubificoides heterochaetus is reported for the first time from Denmark.

First Time

In the north-west of Wilts is a district which contains some remarkable reminiscences of the two dominant races who have influenced the history of this country. In tracing out the history of this district, as it has come down to us by the traditions and records of early chronicle writers, we arrive at an important epoch when for the first time is brought into strongly marked prominence the outline of the community which had settled there. This community, known to us later under the local name of Malmesbury, is one of the most perfect types of the primitive village which has survived in England, and to the elucidation of its chief characteristics it is proposed to devote some little attention. Keeping before us the outline made known from early records we shall see how this is gradually filled in from facts, which though gleaned from later and modern records, are nevertheless stamped as belonging to the earliest stages of history. And when this local mosaic is completely pieced in we shall be able, I think, to satisfy ourselves that what has so persistently clung to locality in later days originally belonged to a social group, types of which are still to be found in Eastern Europe and India, where society is in a state of arrested progress and has not advanced along the lines which mark its development in Western Europe.

Background: To investigate the diversity of the genus Aedes present in the natural areas of Ardabil Province, north-west of Iran. Methods: This cross-sectional study was carried out from Apr to Oct 2016 in North-western of Iran. Thirty-three areas of 10 cities which are border areas were selected randomly. The larvae were collected 2 times in each month during the seasonal activities of mosquitoes and the larvae were identified morphologically according to the appropriate identification keys. Results: Overall, 694 larvae were collected from four counties, from which only 7.2% were Aedes larvae. Three species of Aedes were identified which include Ae. caspius, Ae. vexans and Ae. flavescens. Aedes flavescens is reported from Ardabil Province for the first time. Conclusion: Aedes species were a high density in borderline of Iran and Azerbaijan. Therefore, the north parts of Ardabil Province are a suitable habitat for Aedes species mosquitoes. Care should be taken for vector control in the case of occurrence of any arboviruses transmitted by Aedes mosquitoes.

Young Criminal Lives is the first cradle-to-grave study of the experiences of some of the thousands of delinquent, ‘difficult’, and destitute children passing through the early English juvenile industrial school and reformatory system. Applying biographical research methodologies to digital data, we have reconstructed the lives, families, and neighbourhoods of 500 children who were sent to reformatory and industrial schools in the north-west of England from courts around the UK over a fifty-year period from the 1860s onwards. For the first time, we have been able to follow these children on their journey in and out of institutional care, and then though to their adulthood and old age. We centre on institutions celebrated in this period for their pioneering approaches to child welfare and others that were investigated for cruelty and scandal. Both were typical of the new kind of state-certified provision offered, from the 1850s onwards, to children who had committed criminal acts, or who were considered ‘vulnerable’ to predation, poverty, and the ‘inheritance’ of criminal dispositions.

AbstractDuring 2002-2004, a survey of entomopathogenic nematodes was conducted for the first time in Iran throughout the three provinces in the north-west of the country. Soil samples were tested for the presence of steinernematid and heterorhabditid nematodes by baiting with Galleria mellonella larvae. Of the 833 soil samples studied 27 were positive for entomopathogenic nematodes (3.2%), with 17 (2.0%) containing Heterorhabditis and ten (1.2%) Steinernema isolates. Morphological and molecular studies were carried out to characterise isolates. The Heterorhabditis isolates were identified as Heterorhabditis bacteriophora and Steinernema as Steinernema carpocapsae, S. bicornutum and S. feltiae. Heterorhabditis bacteriophora was the most common species, which was isolated from 17 sites across the three provinces. Steinernema feltiae was the most common species of Steinernema, which was isolated from eight sites but in only two provinces. Steinernema carpocapsae and S. bicornutum were each isolated from only one site. Steinernema spp. were isolated mainly from orchards and grasslands but Heterorhabditis was isolated mainly from grasslands and alfalfa fields.

Length–weight relationships, sex-ratio, maturity patterns, size at first maturity, reproductive outputs, fecundity and spawning period of horned octopus Eledone cirrhosa in north-west Iberian coast are presented for the first time. Samples were collected between February 2009 and July 2011 in four fishing ports along the north-west Iberian coast: Burela in north Galician waters (NGW), Ribeira or Bueu in western Galician waters (WGW), and Aveiro in western Portuguese waters (WPW). A total of 4127 individuals (1042 males, 3079 females and six undetermined) were sampled. Individuals ranged from 45 to 191 mm dorsal mantle length (ML) and 15–1159 g body weight (BW). The overall sex-ratio was biased towards females, accounting for 74.71% of whole sample. Main spawning season of this species in north-western Iberian waters extends from May to June. Size at first maturity (ML50%) of males was 108.9 mm in NGW, 99.25 mm in WGW, and 91.4 mm in WPW, whereas ML50% for females were 134.5 mm, 121.4 mm and 100.8 mm, respectively. Potential fecundity was 2452.88 ± 36.4 oocytes per ovary (N = 697). Mean oocyte length was 3.89 ± 0.025 mm (N = 697). The average number of fully developed spermatophores in mature males was 86.55 ± 1.9 (N = 223) with a mean length of 44.97 ± 0.29 mm (N = 224). Potential fecundity in females was significantly (P < 0.05) correlated with ML and BW. Results obtained suggest that energy for gonad growth comes from the diet rather than endogenous reserves.
