The paper presents the results of phytosociological research on the thermophilous oak forest Potentillo albae-Quercetum Libbert 1933 nom. invers., which has been carried out in the central part of the Kraków-Częstochowa Upland. The association, which has been stated in 7 localities, is a new type of forest vegetation in this region. On the basis of 35 relevés, made in 2001 following the Braun-Blanquet method, the only subassociation P.a.-Q. brachypodietosum pinnati has been distinguished. It has been divided into two variants: with Pleurozium schreberi (on acid sites), and with Asarum europaeum (on basic ones). The investigated phytocoenoses abound in floristic peculiarities, such as: Adenophora liliifolia, Bupleurum longifolium, Euphorbia angulata, Festuca amethystina ssp. ritschlii, Lilium martagon, Potentilla alba.

Promoting the intelligent upgrades of small and medium-sized enterprises is one of the important tasks of implementing “Made in China 2025” in China. As a front runner of nation-level reform, Zhejiang Province has provided much room for innovation and development, along with the emergence of a new type of ecology, accelerated formation of two ecosystems and international cooperation, and a supportive policy environment. Therefore, this paper uses 173 Small and Medium-sized Enterprises (SMEs) from Zhejiang Province as the research objects, builds a binary selection model, and analyzes the dynamic and constraining mechanism of intelligent upgrades of SMEs with regard to employee qualification, technology, capital, policy environment, and so on. The study finds that: First, among three main industries, manufacturing is the major industry for the intelligent upgrades of SMEs and there are significant demonstration effects and industry heterogeneity. Secondly, the willingness to upgrade intelligently for SMEs is relatively strong. More than half of SMEs that have not intelligently upgraded show willingness to implement intelligent upgrades. Thirdly, factors such as corporate profitability, human capital quality, and industry intelligence level have significantly promoted the intelligent upgrades of SMEs, while the impact of labor cost, capital structure, government subsidies, and other variables are not significant. This conclusion still works after a number of robustness tests. Last but not least, based on the above conclusions, this paper proposes corresponding policy recommendations which are practically beneficial to the development of SMEs in China.

The Dolos, a new type of armour unit which closely resembles a normal ship's anchor, was developed and tried out under field conditions on the main breakwater of East London harbour. Since these full-scale Dolosse proved very successful, tests were made in a wave channel to compare the stability of Dolosse with other known types of armour blocks. The test results showed that the Dolos is outstandingly stable, and since manufacture and random placing of Dolosse offers no particular difficulties it is concluded that in many cases the use of Dolosse in armour layers may lead to more economical solutions for rubble mound breakwater and shore protection works.

The notion of governmentality was first used by the French postmodern philosopher Michel Foucault during his lectures at the College de France in 1978-1979. The term is one of the characteristics of political power, along with sovereignty and discipline, but it characterizes its later stages of evolution. Foucault and his commentators give multiple meanings to this term, but perhaps the most accurate ones are the definition of governmentality as a way of rational thinking about the realization of political power and governmentality as the art of government. The emergence of governmentality is associated with the emergence of political economy and implies the use of biopolitical techniques, a concept that Foucault introduces to emphasize the need for socio-hu- manitarian knowledge in disciplining the “political body”. Evolution and peculiarities of biopolitics are discussed in detail in this article in relation to each type of governmentality. This article examines three types of governmentality (liberalism, authoritarianism, neoliberalism) introduced by the French thinker and proposes considering a new type of governmentality that characterizes the modern stage of society’s development. Here we use a governmentality concept as a methodological instrument for analysis of a new type of governance. The author notes that digital governmentality is characterized by governance using digital platforms. The article provides a detailed description of the architecture of one such platforms, as well as a set of algorithms that will mediate the interaction between the population and government representatives. The purpose of this article is to identify the essence of digital governmentality and its nature. Is the emerging form of public governance through digital platforms, as a consequence of its digitalization, demo- cratic and participatory, or is it still a more sophisticated way of governing the population using manipulative, biopolitical strategies? An attempt to answer this question is made in the article by considering both the evolution of the term governmentality itself and the technological features of digital platforms with their interpretation based on Michel Foucault’s concept.

The paper describes experimental investigations made in the mechanical engineering laboratory at Delft, in the field of cyclone separators. These investigations aimed first at determining the most efficient shape of a cyclone, by measuring the effect of a variation of each of its principal dimensions on the efficiency; as a result, a very efficient cyclone shape was developed. The influence of the position of a cyclone on the efficiency was examined, and a new type of cyclone with curved axis, horizontal gas exhaust, and vertical downward dust outlet was constructed. The flow of gas and dust inside a cyclone was examined. The static pressure and the three components of the gas velocity at different points in a cyclone were measured with a globe-Pitot tube. In a cyclone exhausting to atmosphere, a core of low pressure extends over the entire height of the cyclone. Inside this core the flow is very turbulent and unsteady, so that the gas velocities cannot be measured exactly; outside, the pressure is high throughout the remainder of the cyclone. With the exception of the turbulent area in the centre, the total velocity of the gas deviates only slightly from the tangential component V t, which increases as the distance from the centre of the cyclone diminishes. The vertical component V h is directed downwards along the cyclone walls and carries the dust particles to the bunker, and the radial velocity V r is directed towards the centre in the greater part of the cyclone; but in the very turbulent centre, V r is directed outwards and V h upwards. From these measurements a simple cyclone theory was developed, enabling the approximate calculation of the size of the largest dust particles that may escape a cyclone. The effect of a variation in the quantity of gas on the efficiency was determined; this effect was small for a well-constructed cyclone. Efficiencies are given for different sizes of similar shaped cyclones and for various sizes of dust particles. These data enable the selection of a cyclone collector suitable for a particular kind of dust, and the choice of cyclone dimensions for a given efficiency. A method of measuring the dust content of a gas-flow, by means of a small cyclone, is described.

In two earlier papers dealing with the hyperfine structures in the spark spectrum of iodine (Part I (Tolansky 1935) and Part III (Tolansky and Forester 1938)), the partial analysis of a large number of lines has been reported. The basis of the analysis made in Part III was the multiplet classification given by Lacroute (1935), according to which the lines reported in Parts I and III belong largely to the ( 4 S) and ( 2 D) systems, intercombinations being rare. If this classification is correct, certain anomalies arise in the interpretation of the hyperfine structures, as already discussed in Part III.

Oak forest vegetation in the northern part of the Štiavnické vrchy Mts (Central Slovakia)The phytosociological research of the oak forest vegetation was carried out in the northern part of the Štiavnické vrchy Mts (Central Slovakia) using the standard Zürich-Montpellier approach. The data set consisting of 41 phytosociological relevés was obtained by the authors in two vegetation seasons in 2008 and 2009. The numerical classification and the ordination methods were applied to determine the main vegetation types and to explain the structure of the vegetation-environmental data matrix, respectively. Four associations within two classes were distinguished:Luzulo albidae-Quercetum petraeaeHilitzer 1932, typical for shallow, mineral-poor and acidic soils,Melico uniflorae-Quercetum petraeaeGergely 1962 occuring on mesic stands with skeletal and deeper soils,Poo nemoralis-Quercetum dalechampiiŠomšák et Háberová 1979 developing on moderately canopyopened stands in the submontane belt,Sorbo torminalis-QuercetumSvoboda ex Blažková 1962 growing on moderately acidic substrates in drier regions. The major environmental gradients responsible for variation in forest species composition was associated with soil nutrient and soil reaction following the Ellenberg indicator values as well as the measured environmental variables (C/N-ratio and soil acidity). Special attention was given to the discussion on species composition and site ecology.

In a recent article on supercharging, various practical conditions are given which place limits on the degree of supercharging possible with aero engines. Some time ago the writer was shown the results obtained with a supercharged engine and, although the performance was very creditable up to an altitude of 12,000 feet, above this altitude there was a remarkable decrease in power, this decrease being so considerable that it could not be readily accounted for. Various modifications were made in an attempt to improve the engine's performance at the higher altitudes, but without success, and it was only after a new type of carburettor had been fitted that improved results were obtained.

Zeolite Composite

Selective catalytic reduction of NO with methane (NO-CH4-SCR) in the presence of excess oxygen was investigated over the synthesized MnH-ZZs-n zeolite composite catalysts with FAU (as core) and BEA (as shell) topologies. XRD, SEM, and NH3-TPD technologies were employed to characterize the catalysts. It is found that the topological structure of the zeolite affected the catalytic properties and H2O/SO2 tolerances considerably. MnH-ZZs-n catalysts exhibited much higher NO-CH4-SCR activity than the physical mixture catalysts with comparable relative mass content of Y and Beta zeolites, particularly the ratio of Y and Beta at the range of 0.2–0.5 than the MnH-Beta catalysts with single topology. NH3-TPD results showed that one new type of strong acidic sites formed in H-ZZs-n and remained in MnH-ZZs-n resulted from the interaction between the Lewis and Brönsted acid sites under a particular environment. The special zeolite-zeolite structure with ion-exchanged Mn ions in the core-shell zeolite composite catalysts contributed to the novel NO-CH4-SCR properties.
