Аннотация: This volume is dedicated to the centenary of the outstanding mathematician of the XXth century Sergey Sobolev and, in a sense, to this celebrated work "On a theorem of functional analysis@ published in 1938, exactly 70 years ago, where the original Sobolev inequality was proved. This double event is a good case to gather experts for presenting the latest results on the study of Sobolev inequalities which play a fundamental role in analysis, the theory of partial differential equations, mathematical physics, and differential geometry. In particular, the following topics are discussed: Sobolev type inequalities on manifolds and metric measure spaces, traces, inequalities with weights, unfamilar settings of Sobolev type inequalities, Sobolev mappings between manifolds and vector spaces, properties of maximal functions in Sobolev spaces, the sharpness of constants in inequalities, etc. The volume opens with a nice reminiscence "My Love Affair the Sobolev Inequality" by D.R. Adams.

Fertilizer distribution and sampling techniques in the aerial fertilization of forests
[Текст] / K.A. Armson. - Toronto : University of Toronto, Faculty of Forestry, 1972. - 27 с. : figures + tables. - (Technical Report ; 11). - Библиогр: p. 25-26. - 0-60 р.
Аннотация: A study was made of the actual rates and distribution patterns of aerially applied urea fetilizer using norminal rates of 50 and 100 lb./ac. nitrogen. It was concluded that: 1. The variation in distribution at the 50 lb./ac. N rate was great enough to render such application unsuitable. 2. The amount of fertilizer monitored falling through the tree canopy (jack pine, Pinus banksiana Lamb.) was similar to that monitored in open strips. 3. At nominal rates of 100 lb./ac. N, monitoring catchers of 1 square foot area were as suitable as those of 2 square feet area. 4. The estimated numbers of monitoring catchers needed to measure urea fertilizer at 100 lb./ac. N rate was determined for various assumed levels of accuracy. 5. It was suggested that narrow rectangular monitoring plots using 10 catchers each be used to determine fertilizer distribution and tree growth plot locations. 6. Growth responses to fertilizer treatments are more realistic when related to both a response curve and the area distribution of fertilizer. A system of monitoring catchers and plots is recommended which will enable this to be accomplished. 7. The use of cacodylic acid to kill trees in lines, so that the dead red brown foliage would provide marker lines for the aircraft feasible. It should be noted that although jack pine (Pinus banksiana Lamb.) and balsam fir (Abies balsamea (L.) Mill.) retain their dead foliage for a year or more, the foliage of spruces Picea falls after the tree's death.

Verkernung und weitere verwenungsrelevante Eigenschaften von Douglasien-Schwachholz aus unterschiedlich behandelten Jungsbestanden
[Текст] : folgerungen fur die Sortierung und die industrielle Verwendung von Douglasien-Schwachholz / F. Hapla. - Frankfurt am Main : J.D. Sauerlander's Verlag , 1999. - 206 с. : Ill. - (Schriften aus der Forstlichen Fakultat der Universitat Gottingen und der Niedersachsischen Forstlichen Versuchsanstalt, ISSN 0344-5666 ; 127). - Библиогр: S. 156-170%ISBN 3-7939-5127-8. - 125-00 р.
Аннотация: According to the latest forest inventory in Germany the total area of Douglas-fir plantations is approximately 134.000 hectares. At present approxomately 80% of these stands are in the first and second age classes (less than 40 years old). Therefore the majority of the growing stock is composed of small sized timber. As a result of the present situation in the timber market the utilization of small sized Douglas-fir timber from thinned stands is problematic. The following conclusions are drawn. By planting Douglas-fir stands with 1800 to a maximum of 2500 trees per hectare it should be possible within the first thinning measure to reduce the amount of the small sized timber which is difficult to sell. The thinnings offer better possibilities of utilization and cosequently for sale because of their larger dimension, their high portion of heardwood and their more homogenous inner wood properties and also because of a higher portion of sawlog stem sections. With the recommended number of plants per hectare it should also be possible to grow stable stands for high value timber production.

Uber die Eignung verschiedener physikalisch-technischer Verfahren zur phytosanitaren Behandlung und zur Lagerung von Forstsaatgut unter besonderer Berucksichtigung der Stiel- und Traubeneiche=On the suitability of various physical-technical methods for treatment and storage of tree seeds, especially acorns
[Текст] : монография / T. Schroder. - Berlin : Parey Buchverlag, 1999. - 241 с. : Ill. - (Mitteilungen aus der Biologischen Bundesanstalt fur Land- und Forstwirtschaft Berlin-Dahlem, ISSN 0067-5849 ; 360). - Библиогр: S. 193-214%ISBN 3-8263-3244-X. - 150-00 р.
Аннотация: In this study, several alternative phytosanitary treatments for forest tree seeds in general were evaluated and experiments on the long-term storage of acorns were conducted. Seed treatments with low-energy electron beams were carried out on acorns, beechnuts, and seeds of Sitka spruce. This method, the effect of which is restricted to the outer seed parts, is based on the biological effect of ionising radiation and is intended to kill microfungi in the pericarp and testa. The second evaluated phytosanitary measure consisted of the microwave treatment of acorns, which relies on a thermal effect. In addition, the phenomenon of artificially induced frost hardiness of acorns was examined in order to explore the possibility of storing acorns at temperatures lower than the present limit of -3 C.

Pests and diseases of forest plantation trees

Аннотация: The organisms listed in this book include only those that are directly, or in a few instances indirectly, injurious to living trees. Species, such as many wood-boring insects, whose attacks are restricted to fallen trees have been exluded. Weed plants, unless they are at least in some measure parasitic, have also been omitted. Many of the included tree species are most commonly, but not invariably, treated as agricultural crops, and on the borderline the inclusion of some and the omission of others must necessarily be subjective; the principle of including too much rather than too little has been adopted.

Wind measurement with hydrogen-filled balloons
[Text] / J.L. Adams. - Ottawa : Department of Forestry, 1963. - 69-72 p. : рис. - (Forest Research Branch Contribution ; № 527). - eng. - 0.05 р.
Аннотация: This report describes trials of hydrogen-filled balloons, tethered to the ground, and used to measure the speed and direction of light air currents (0-5 miles per hour) near or around experimental fires. The hypothesis was that when a tethered balloon is displaced by a certain wind speed, the angle between the tether and the vertical ("angle of lean" of the balloon) can be correlated with the speed of the wind. This hypothesis was investigated at the Petawawa Forest Experiment Station at Chalk River, Ontario, in the summer of 1962

This hypothesis was investigated at the Petawawa Forest Experiment Station at Chalk River, Ontario, in the summer of 1962

Plant hormones and their role in plant growth and development
[Text] : сборник научных трудов / Ed. by P.J. Davis. - Dordrecht ; Boston ; London : Kluwer Academic Publishers, 1987. - 681 p. : рис., табл. - eng. - Библиогр. в конце ст. - ISBN 90-247-3498-3 : 99.00 р.
Аннотация: Plant hormones play a crucial role in controlling the way in which plants grow and develop. While metabolism provides the power and building blocks for plant life, it is the hormones that regulate the speed of growth of the individual parts and integrate these parts to produce the form that we recognize as a plant. In addition, they play a controlling role in the processes of reproduction. This book is a description of these natural chemicals: how they are synthesized and metabilized; how they work; how we measure the; and a description of some of the roles they play in regulating plant growth and development

Canada's domestic consumption of forest products: 1960-2000
[Text] : доклад, тезисы доклада / D. Roberts, D. Luck. - Ottawa : Economics Branch, Canadian Forestry Service Government of Canada, 1985. - (Information Report E-X-35). - eng. - Библиогр.: с. 41. - ISBN 0-662-13703-5 : 2.50 р.
Аннотация: This report examines the domestic consumption patterns of forest products for the period 1960-2000 as well as projecting the domestic consumption. The projection methodology involves a two-step procedure. First, multiple regression analysis is used to relate the consumption of a specific forest product to a distributed lag of some general measure of economic activity (e.g. real gross domestic product in the construction industry). Second, forecasts of the measures of economic activity up to the year 2000 are obtained and placed into the models developed in step 1 in order to generate the final projections.

Co2 production as a measure of decay activity in wood blocks
[Text] = Co2-produktion som ett matt pa rotaktivitet i traklossar : научное издание / A. Klingstrom. - Stockholm : Skogshogskolan, 1965. - 20 p. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 26). - eng. - Библиогр.: с. 19. - Б. ц.
Аннотация: Basically, a decay process in wood can be described as an aerobic breakdown of wood under the development of CO2 and H2O. Less intense processes, not investigated in this paper, can also take place under anaerobic condidtions. Weight-loss tests are the most common method for measuring the decay. These tests are time consuming and are fraught with various practical difficulties. The purpose of this investigation was to study the CO2 output of decaying wood. A simple method which made very small demands on laboratory equipment was used. The method is compared with weight-loss tests

Maskinellt skogssarbete i konstljus. Ergonomiska aspekter pa syn- och belysningsforhallanden. En studie inom det internordiska (NSR-) projektet "Forhallandet mellan man och maskin for skogsbrukets maskiner"
[Text] = Artificial lighting in forest machine operations. Ergonomic aspects of sight and light : научное издание / H. Teljstedt. - Stockholm : Skogshogskolan, 1974. - 74 с. : рис., табл. - (Studia Forestalia Suecica, ISSN 0039-3150 ; № 120). - eng. - Библиогр.: с. 63. - ISBN 91-38-02097-1 : 0.50 р.
Аннотация: The aim of the project was to investigate the existing lighting conditions and give suggestions for suitable lighting arrangements as well as other measures that can make work in artificial light easier and safer. The investigations have been done both as limited model tests and in connection with actual field work. The lighting conditions can be improved through the use of broad beam lamps, stronger generators, more lamps and through black-painting certain parts of the machines.

Аннотация: This monograph on the pine bark bug is the result of many years' reserach work in Scandinavia and other countries. The author gives a historical survey of the places of discovery of this insect, which, not so long ago, was hardly regarded as harmful in the West-European countries. The damage is done by sucking out the cell juice of young pine trees which causes deformity and destruction of the vessels. The damage done by the insect has been explained by means of experimental work and observations. This insect is only to be found on Scots pine and larch. It prefers clean, dry and warm places and likes pine cultures on light soil. The thick, shadowy, and mixed cultures are only attacked at the edges. The consequences of the appearnce of the insect depend mainly upon the size of the insect population and the age of the tree. The chances fro 6-10-year-old pines to endure an attack are very small. The necessary prophylactic measure to be taken is to plant the cultures with closer planting space. It is possible to achieve successful results in the control of this insect by fertilizing with nitrogen and also by using the insecticide lindan.

[Text] : научное издание / T. Lahti. - Helsinki : The Finnish Society of Forest Science-The Finnish Forest Resaerch Institute, 1995. - 68 p. : рис., табл. - (Acta Forestalia Fennica, ISSN 0039-3150 ; № 246). - eng. - Библиогр.: с.52-55. - ISBN 951-40-1435-9 : 3000.00 р.
Кл.слова (ненормированные):
classification -- estimation -- forest vegetation -- Norway spruce -- Scots pine -- site quality
Аннотация: The relationship between characteristics and understorey vegetation composition was analysed with quantitative methods, especially from the viewpoint of site quality estimation. Theoretical models were applied to an emperical data set collected from the upland forests of southern Finland comprising 104 sites dominated by Scots pine and 165 sites dominated by Norway spruce/ Site index H100 was used as an independent measure of site quality.
