Статья вводит в научный оборот материалы погребений эпохи энеолита, происходящие из кургана, расположенного на Среднем Дону (Воронежская область). Обнаруженный в кургане инвентарь (керамика с примесью раковины, подвески из зубов оленя, наконечники стрел и орудия из кремня, металлические пронизки) в совокупности с абсолютными датировками указывает на энеолитическую принадлежность публикуемого комплекса (втор. пол. V тыс. до н. э.). Спорово-пыльцевой анализ погребенной почвы под курганом свидетельствует о кратковременном похолодании и повышенной увлажненности в период сооружения кургана. The paper introduces into scientific discourse materials from Eneolithic burials in a kurgan located on the Middle Don (Voronezh region). Funerary offerings discovered in the kurgan (ceramics with crushed shells admixture, pendants made from deer teeth, arrowheads and flint tools, metal tubular beads) along with the absolute dates obtained demonstrate that this assemblage dates to the Eneolithic (second half of V mill. BC). The pollen analysis of the buried soil under the kurgan reveals short-term cooling and a high moisture level at the time when the kurgan was erected.

The recalcitrant seeds need a high moisture level during in storage to prevent loss its viability. The storage at a high moisture level is a favorable condition for fungi growth and on the other hand, a low seeds moisture level will loss the seeds viability. The citrus seeds as one of recalcitrant seeds need a special condition in storage. The storage of citrus seeds by using kencur (Kaempferia galangal L.) extract can protect the seeds against fungi during storage and preserve its viability. The purpose of this research was to determine the best concentration of K. galanga extract which protects the citrus seeds against fungi as long as period storage, the kind of fungi and its percentage of infection, and the citrus seeds viability. This research was carried out in September until November in 2004 at Plant Pest and Disease Laboratory and Greenhouse of Agricultural Faculty of Sebelas Maret University. The citrus seed used was Keprok variety from Ponorogo. The research design was a Randomized Completely Block Design (RCBD), with the treatments: (1) included the seeds without being stored and without being given by K. galanga extract, (2) the seeds were stored for 2 weeks with 100%, 75%, and 50% K. galanga extract, (3) the seeds were stored for 4 weeks with 100%, 75%, and 50% K. galanga extract, (4) the seeds were stored for 6 weeks with 100%, 75%, and 50% K. galanga extract, and (5) the seeds were stored for 8 weeks with 100%, 75%, and 50% K. galanga extract. Data were analyzed by using F test with 5% and 1% significance levels. If there were real differences, it was continued to be tested by using a Duncan multiple range test with 5% significance level. The results of this research showed that K. galanga extract by 50% was the best concentration that protected the citrus seeds against fungi for 2 weeks of storage. The storage of citrus seeds with K. galanga extract more than 2 weeks decreased seeds viability. The dominant kinds of fungi that attack citrus seeds in the storage were Aspergillus spp. and Penicillium spp., obtained by using a blotter test.

Portable unilateral NMR was used to quantitatively map in a fully noninvasive way the moisture distribution in an ancient deteriorated wall painting before and after an intervention to reduce the capillary raise of water through the wall. Maps obtained at a depth of 0.5 cm clearly showed the path of the capillary raise and indicated that, after the intervention, the moisture level was reduced. Maps obtained by measuring the first layers of the wall painting were affected by the critical environmental conditions of the second hypogeous level of St. Clement Basilica, Rome, and by the presence of salts efflorescence and encrustations on the surface of the wall painting. The morphology and the elemental composition of salts investigated by SEM-EDS indicated that efflorescences and encrustations were mostly constituted of gypsum and calcite. The presence of these salts is explained with the presence of high concentration of carbon dioxide and sulphur-rich particles due to pollution which, along with the high-moisture level and the extremely feeble air circulation, cause recarbonation and sulphation processes on the plaster surface.

Crop residue mineralization affects soil carbon (C) and nitrogen (N) dynamics during crop residue management in crop production. C and N mineralization dynamics of rice and wheat residues incorporated with and without mineral N under two moisture conditions were evaluated under laboratory conditions. Mineral N was applied @ 0.015 g/Kg (»30 Kg/ha), whereas soil moisture was maintained at high (» – 15 KPa, near field capacity) and at low (» – 500 KPa)moisture levels during course of study.Periodic determinations on CO2 – C and N mineralized were performed over a period of 120 days. The highest peaks for CO2 – C occurred during first week of the study which then reduced gradually until it attained an equilibrium. High moisture level enhanced CO2 – C flux by 14% than low moisture level. Combined application of crop residues and mineral N released 17% more CO2 – C than crop residue treatments without mineral N.In residue applied treatments, immobilization was 40% higher at high moisture level than that at low moisture level. Application of rice and wheat residues in combination with mineral N caused both immobilizations followed by mineralization phases at both moisture levels. At high moisture level, maximum immobilization occurred during initial 15 days, while at low moisture level it continued till about 30 days. After day15, mineralization started which continued to increase during remaining period of study at high moisture and at low moisture mineralization initiated from day 60 onward. Mineralization in rice residue was faster than that in wheat residues. Immobilization of N continued progressively in residue alone treated soils at both moisture levels during study period. In residue treated soils, increase in soil moisture increased soil organic carbon (SOC) and soil water stable aggregates (WSA) significantly by 14% and 55% over control respectively.Combined application of crop residues and mineral N increased SOC by 43% and WSA by 59%. This study indicated that incorporation of crop residues along with addition of mineral N in the presence of optimum moisture promoted its faster decomposition with a quicker mineral N release, more organic matter build up and soil structure improvement than crop residues incorporated without mineral N.

High Moisture Level

Many factors, both inherent and environmental, affect the linamarin content of flax (its cyanogenetic principle). Redwing variety contains considerably more potential cyanide than does Royal. Flax, maintained at a high moisture level throughout the growth season, contains significantly less linamarin than that grown with access to less soil moisture. Frost, mechanical injury, and drought all affect the cyanogenetic content of flax adversely, the effect of the first being very great. Flax grown at the higher moisture level was more affected by these conditions than was flax grown at the lower moisture level. The recovery of cyanide from the glycoside by simultaneous enzymatic hydrolysis and aeration, and its estimation by the alkaline silver nitrate method, is an effective laboratory means of assessing the cyanogenetic content of flax. Although acetone, one of the decomposition products of linamarin, normally reacts with the alkaline picrate reagent, picrate under certain conditions may be adapted to the roughly quantitative estimation of cyanide by test paper in the field.

Abstract Remains of the grand platform in the locus of Huangchengtai at Shimao site in Shenmu, Shaanxi was discovered and excavated during the 2018–2019 season. The south-eastern corner and southern buttress of the platform were revealed. The locations of the other three sides of the buttresses were also preliminarily confirmed. As many as 70 stone carvings were discovered from multiple contexts, including the surface of the southern buttress, the floor of the corridor, as well as the debris of the southern buttress inside the corridor. The relative chronology of this platform and stone carvings cannot be later than the late Longshan period. The absolute date ranges from 2000 BCE to 1800 BCE. Fieldwork performed at the grand platform encourages multiple archaeological discussions, including the settlement layout within the Huangchengtai area, the nature of the settlement, and its role as the core of the Shimao site.

В статье рассматриваются фамилии жителей ряда сел Воронежской области, восходящие к топонимам и катойконимам. Материалом исследования послужили более 1300 антропонимических единиц в синхронии и 275 в диахронии (по данным ревизских сказок 1816 года). Целью данной статьи является установление различных видов топонимических реликтов в воронежских фамилиях (на примере ряда сел Поворинского, Новохоперского, Таловского районов Воронежской области) с использованием описательного и сравнительно-исторического методов. В результате исследования с лексико-семантической точки зрения выделены следующие типы топонимических реликтов: 1) топонимические реликты, восходящие к разновидностям топонимов - ойконимам (собственным именам поселений); 2) топонимические реликты, восходящие к катойконимам - оттопонимным образованиям (нарицательным именованием жителей по названию места жительства); 3) топонимические реликты, восходящие к гидронимам - собственным наименованиям водных объектов. Топонимическую основу имеют 2,5% от общего числа рассмотренных антропонимов. Анализ сохранившихся в фамилиях топонимических реликтов, классифицированных в соответствии с основами онимов, позволяет сделать вывод о том, что в Воронежский край переселялись жители из разных областей Центральной России, с юга России - Ростовского края, Белоруссии, а также с Украины, что подтверждают и исторические документы. The article deals with the surnames of a number of villages in Voronezh region that go back to toponyms and kataikonyms. We have used more than 1300 anthroponymic units in synchrony and 275 indiachrony (according to the revision lists of 1816) as the research material. The purpose of this article is to establish various types of toponymic relicts in Voronezh surnames (exemplified by a number of villages of Povorinsky, Novokhopersky, Talovsky districts of the Voronezh region) using descriptive and comparative historical methods. As a result of the study, we have identified the following types of toponymic relicts from lexical and semantic pointы of view: 1) toponymic relicts dating back to the varieties of toponyms - oikonyms (proper names of settlements); 2) toponymic relicts dating back to katoikonyms - toponym formations (common names of people derived from the name of the residence place); 3) toponymic relicts dating back to hydronyms - proper names of water bodies. 2.5% of the total number of considered anthroponyms have a toponymic basis. Ananalysis of the toponymic relicts preserved in the surnames, classified in accordance with the basics of onyms, allow us to conclude that residents from different regions of Central Russia, from the South of Russia - the Rostov region, Belarus, as well as from Ukraine moved to the Voronezh region, which is also confirmed by historical documents.

Water conduction and wood anatomy of Salix sachalinensis attacked by watermark disease were investigated. The internal symptom, the watermark, appeared as a brown to brown-black stained zone in sapwood. Dye injection tests revealed that water conduction did not take place in the watermark. However, soft X-ray photography and cryo-scanning electron microscopy revealed that the watermark had a high moisture level. In the watermark, some of the vessels were plugged with tyloses and masses of bacteria, and some of the ray parenchyma cells caused necrosis. Hence, the non-conductive watermark in sapwood can be considered similar to discoloured wood or wetwood.
