Published: November 2019

Abstract
A three-dimensional numerical model of Guangxi coastal hydro-dynamical environment was constructed based on ECOMSED to study the COD transport with fine grid based on latest coastline and bathymetry data. The experiment results showed that the trace of COD was mainly affected by the flood and ebb tide in coastal regions; The area in Qinzhou Bay with COD concentration exceeding 1mg/L, 3mg/L and 6mg/L on the 31th day was 60.5km2, 14.8km2 and 3.7km2 respectively. The corresponding results at Nanliu river estuary was 64.7km2, 23.1km2 and 0 km2 respectively. The COD-polluted water at the Nanliu river esturay spread more widely but no concentration larger than 6mg/L was found, which could be explained by the different topographic conditions in these two places. The vertical distribution of COD transport was approximately the same as in surface, except that the area exceeding 1mg/L decreased slightly in the middle and bottom layer.

Authors: Slavskiy V 
Published: November 2019

Abstract
Taking into account the emerging trend towards temperature increase in the region of the research in recent years, introduction and cultivation of the genus Juglans in the Voronezh region is a pressing issue. The paper reviews 4 species of nuts – black walnut, Manchurian, gray and heartnut, which are the most promising for the creation of forest crops, because they are the most resistant to adverse factors in the area of introduction among all species of the genus Juglans. Taking into account the specific features and the intense form diversity of nuts of the genus Juglans, an assessment scale was proposed and a regional methodology was developed for assessing the quality of fruits. The quality of the fruits of the forms and types of nuts was determined by the total value of the evaluation criteria, taking into account the level of significance of each trait. The trees species which in aggregate have the best resistance to adverse factors and have acceptable quality fruits (EC = 136 and 188) are black walnut and heartnut. It is these types of the genus Juglans that are primarily recommended for full reforestation and afforestation in the Voronezh region.

Abstract
The aim of the article is to find effective growth points for the Russian economy, identify problems hindering the sustainable development according to the green paradigm. The benefits of Russia’s participation in international logistic project of recreating the new Silk Road are researched for forestry industry. Positive dynamics of the forest industry was achieved in 2018: in 10 months of 2018, the industrial production index in the woodworking sector was 109%, in the pulp and paper industry – 113%. Despite the positive trends, the capacity of the industry is far from fully revealed. The share of Russia in world forest turnover is 3% of the global volume unlike such countries as Finland (8%), Sweden (10%), the USA (13%), Canada (17%). The main consumers are China (76%), the Republic of Korea (20%), Japan (4%). Processed timber is acquired by China (83%), the Republic of Korea and Japan (17%). The development of export-oriented woodworking enterprises with high-value-added products in Russia demands a significant transformation of the transport-logistics complex. The article researches the main limitations of the transport system (low density of roads, the high demanding infrastructure investments, high costs of transportation), which do not allow enterprises to work effectively in foreign markets.

Authors: Stepanova Yu , Radykova Yu 
Published: November 2019

Abstract
The Russian forest sector is now undergoing global changes related to the development of digitalization and innovation. Raising the innovation level is a strategically important task for the country. It depends on the conditions created for the development of intellectual resources. Forest is a natural capital, partially forming the country’s national wealth. Russia occupies leading positions in the world forest yield. Attraction of innovation to the forest sector is the urgent task. For a long time, forest sector was unattractive for businesses and investors due to the long cultivation cycle, natural risks and large fire losses. Here innovations should come to rescue. They enable to automate biological processes and gain progress in productivity growth. Innovations should not be borrowed technologies, but created using our own resources. Today, scientists from Germany, Italy, and Costa Rica are looking for different approaches increasing forestry innovative potential. We propose to use knowledge for innovative development of the forest sector: there is a direct relationship between the levels of innovative activity and education. The aim of this article is to create instruments for the forestry innovative development, based on the knowledge economy, leading to the innovation formation.
Real-Time PCR and analysis of amplicon melting curves to assess the suitability of SSR loci of Scots pine for multiplexing
Authors: Kalko G , Kotova T 
Published: November 2019

Abstract
Nuclear microsatellite markers are considered to be among the most powerful tools for assessing genetic resources. To date, a great variety of primers for SSR loci of pines has been developed. As regards Scots pine, selection of neutral steadily amplifiable loci not containing null alleles and their multiplexing are high-priority tasks, as there are no generally accepted multiplex panels of loci for this species. Authors of published multiplexes tend not to use loci due to their unstable amplification or the presence of single nucleotide repeats. The aim of the paper was to create the new multiplexes of reliable previously published pine nSSR loci in view of preliminary data based on the analysis of melting curves of products after Real-Time polymerase chain reaction (PCR) for each locus separately. Initially, microsatellite multiplexes were created using Multiplex Manager 1.0. DNA was extracted by the CTAB method from samples of pine needles. Real-Time PCR was performed in CFX96 thermal cyclers (BIO-RAD, USA). Fragment analysis of PCR products labeled with FAM, HEX and ROX dyes was performed on a 3500 genetic analyzer (Applied Biosystems). GeneScanTM 500 LIZ size standard was used. As a result of the study, 3 multiplexes have been proposed.

Abstract
The subject of this research is new wood polymer-sand composite and the study of its frost resistance using computer experiment. Industrial waste in the form of sawdust, chips, lumpy waste and polyethylene terephthalate are used as the filler. A computer program has been developed for modelling the structure and physical properties of building blocks from wood polymer-sand composite. The program enables to set (in the windows of the interface form in the program code) geometric and physical parameters of building block and material components, as well as test conditions for cyclic heating and cooling to the maximum temperature during operation. It explores the effect of parameters on internal and surface destruction of building blocks. The program is applicable for a wide range of composite component concentrations, building blocks’ geometric parameters, variety of mechanical and thermal cycling tests. The influence of wood polymer-sand composite formulation on the structure has been studied during thermocyclic testing. The dependences of broken bonds on wood concentration, cartograms of bond breaking of wood polymer-sand composite with a wood concentration from 20 to 80% have been obtained. Recommendations for optimizing the formulation of wood polymer-sand composite blocks are given to minimize bond breaking during thermal cycling.

Published: November 2019

Abstract
Forestation during recultivation of disturbed lands may become an additional measure to expand the flow of greenhouse gases for the Russian Federation. The study of forestation potential on disturbed lands is based on analysis of public statistical data on the land distribution according to the grounds as well as data on the areas and growing stocks of forested lands for tree species and age classes in the Leningrad region. In order to establish an potential absorption capacity of recultivated lands, forest stands of the first and second age-classes were chosen as model (with pine, spruce and birch as dominating tree species). On the basis of model forest stands by the method of regional assessment of the forest carbon budget the feasible forestation potential for recultivation of disturbed lands for the areas of Leningrad region is established. Forestation in the stands of the first and second age-classes with dominating of spruce may increase the absorption capacity of the Leningrad region by 1.9 %, stands with dominating of birch by 1.5 % and stands with dominating of pine by 1.3 % per year.
