Opis:
Стаття досліджує одну зі складових історії модернізаційних процесів у країнах Південно-Східної Європи на початку ХХ ст. – військову модернізацію. Мета дослідження – аналіз ролі іноземної військової допомоги у створенні збройних сил Румунії, Сербії, Болгарії, Чорногорії, Албанії та Греції. Розкриваються окремі напрямки військової допомоги, наданої країнам Південно-Східної Європи у вигляді військових місій, навчання офіцерів у Європі, поставок зброї та інших аспектів. Один із маркерів військового розвитку в досліджуваний період – це військово-інструкторська діяльність розвинених держав Європи в межах військової модернізації можливих військових союзників цих країн. Робота присвячена одній зі складових процесу військової модернізації – діяльності військово-інструкторських місій провідних європейських держав у визначений період. Часовий проміжок дослідження – 1908-1918 рр. Нижньою межею дослідження є боснійська криза 1908 р., викликана анексією Австро-Угорщиною Боснії і Герцеговини. Конфлікт послужив причиною швидкої мілітаризації регіону. Воєнні місії з країн Європи починають активну діяльність в Греції, Чорногорії, Туреччині. Тисячі офіцерів з балканських армій проходять навчання у військових закладах Європи. Верхня межа дослідження – Перша світова війна 1914-1918 рр. В той час був досягнутий очевидний успіх в модернізації збройних сил союзників воєнними місіями з Німеччини в Туреччині та Франції в Румунії. Це був час модернізації нових національних армій у Східній Європі. Не останню роль у цьому складному процесі відігравали воєнні місії. Швидко й ефективно досягти якісної модернізації відсталих у розвитку армій, без інструкторської допомоги, було неможливо. Зіставлення результатів перетворень дозволяє точніше зрозуміти регіональну специфіку та конкретні результати цієї форми військової модернізації збройних сил у міжвоєнне двадцятиліття. Використовується метод порівняння варіантів військової модернізації армій країн Сходу, які відбуваються на початку ХХ ст., і реформування збройних сил держав Південно-Східної Європи. Цей метод конкретизує результати, наслідки, невдачі й успіхи військової модернізації. Дослідження є актуальним для вивчення сучасних процесів воєнної модернізації.
This article studies one of the components of the history of modernization processes in the countries of South-Eastern Europe in the latter half of the 19th century – the early 20th century – military modernization. The purpose of research is to analyze the role of foreign military assistance in formation of military forces of Romania, Serbia, Bulgaria, Montenegro, Albania and Greece. Separate directions of military assistance provided to the countries of South-Eastern Europe in the form of military missions, training of officers in Europe, arms export and other aspects are disclosed. One of the markers of military development during the period in question was the military instructor activity of the developed European countries in the framework of military modernization of possible military allies in these countries. The lower limit of research is the Bosnian crisis in 1908 caused by annexation of Bosnia and Herzegovina by Austria-Hungary. The conflict was the reason of rapid militarization of the region. Military missions from the countries of Europe began their activity in Greece, Montenegro, Turkey. Thousands of officers from Balkan army studied in military establishments of Europe. The top limit of the research is the First world war І 1914-1918. The obvious success was attained with modernization of the armed forces of allies by military missions from Germany in Turkey and from France in Romania in that time. The work deals with the process of military modernization, i.e. the activities of military instructor missions of the leading European countries during the interwar period. The time interval of the study ranges within 1908-1918. This was the period marked by modernization of new national armies in Eastern Europe. Military missions played an important role in this complex process. The comparison of the results of transformations provides for better understanding of the regional specifics and concrete results of this form of military modernization of armed forces during the twenty-year interwar period. The method for comparing variations of military modernization of armies of Oriental countries occurring at the turn of the 20th centuries and reorganization of military forces of the countries of South-Eastern Europe is used. This method instantiates results, consequences, failures and success of military modernization. The research is relevant for studying modern processes of military modernization.

Opis:
Leatherleaf Chamaedaphne calyculata (L) Moench is a relict, rare and endangered species in Poland. There are no reports on the micropropagation of Chamaedaphne calyculata in the literature. Therefore, the aim of this study was to propose a propagation protocol for leatherleaf via indirect organogenesis using leaves and stems (internodal segments) derived from mature plants growing in a natural stand and from plants grown in vitro as explants. The medium developed by Anthony et al. (2004) with 100%, 50% and 25% salt concentrations, supplemented with IAA (5 and 10μM) and TDZ (5 and 10μM), was used for callus development and the induction of adventitious shoots. The media developed by Anthony et al. (2004) and Anderson (1980), both containing 10μM TDZ and 5μM IAA or 2.28μM zeatin, were used for adventitious shoot elongation. Secondary explants proved to be the most effective starting material for callus induction, the regeneration and elongation of adventitious shoots. The most supportive medium for callus induction and growth and the induction of adventitious shoots was the full medium proposed by Anthony et al. (2004) containing 5μM IAA and 10μM TDZ. Anderson’s (1980) medium containing 2.28μM zeatin delivered optimal results in the elongation of adventitious shoots of Ch. calyculata. Roots were cultivated on Anderson’s (1980) phytohormone-free medium. Approximately 65% of the plantlets survived after transfer to the sphagnum-peat and perlite mixture (3:1). The plants grew normally without any signs of morphological variation. This study makes the first ever attempt to propose an effective micropropagation protocol for Ch. calyculata.

Opis:
Copper is an essential trace element in living organisms, but its excess interferes with metabolic transformations in plant, animal and human cells. The uptake of copper from contaminated soils can be regulated, for example, by soil liming or application of other substances which enhance soil adsorption capacity and Cu binding in the substrate. The purpose of this study has been to assess the response of maize to soil contamination with copper depending on the applied neutralizing substances. The tested factors were increasing concentrations of Cu in soil: 0, 200, 400 and 600 mg Cu kg ?1 dm, and soil application of mineral (lime, loam and zeolite) and organic (manure, peat and bark) neutralizing substances. Soil contamination with copper within the range of 200 to 600 mg kg ?1 of soil caused reduction in maize yields. Positive influence such as alleviation of the harmful effect of copper contamination was demonstrated by lime and manure, which enhanced yields of maize, especially in the series polluted with 200 and 400 mg Cu kg ?1 . The other soil amending substances, especially peat added in amounts of 400 and 600 mg kg ?1 of soil, caused aconsiderable depression in maize yields. A linear dependence has been demonstrated between the concentration of Cu in maize plants and the content of Cu in the substrate, with the root content of Cu being on average six-fold higher than in aerial organs. Mineral soil amendments significantly decreased the BTC index in maize compared to organic substances, and lime as well as pine bark decreased the BCF index to 2.33 and 1.67 versus the value of 4.21 found in the control treatment without any neutralizing substances. The uptake of copper depended on the volume of yield and ? to a lesser degree ? on the concentration of Cu in plants. The uptake of copper by plants was the highest in treatmentscontaminated with a rate of 200 mg Cu kg ?1 , which was the consequence of higher yields from that treatment than from the plots polluted with 400 or 600 mg Cu kg ?1 of soil.

Opis:
The electrical properties of the CdTe/ZnTe quantum dot system have been analyzed to identify deep-level defects related with the presence of quantum dots. The capacitance-voltage (C-V) and deep level transient spectroscopy measurements were used to investigate the samples. A reference ZnTe sample (without dots) was also studied for comparison. Both samples were grown by molecular beam epitaxy technique on the n-type GaAs substrate. The quantum dots were formed by a Zn-induced reorganization of a thin CdTe layer. The presence of quantum dot formation was confirmed by micro-photoluminescence measurements. The deep level transient spectra for both samples are complex. In order to characterize individual contributions to the deep level transient spectra the latter have been simulated by separated Gaussian components [1]. The results of the deep level transient spectroscopy measurements yield the conclusion that the same defects are present in both materials but there is an increased concentration of the defects in the quantum dot structures. No deep level associated directly with the quantum dot confinement has been identified.

The aim of this study is to clarify the relation between microstructure and properties (hardness and electrical resistivity) of copper wire drawing by the ENICAB Company and distended for electrical cabling. In this work we studied the evolution of the microstructure and (mechanical/electrical) properties of the wire drawn and annealed at 260°C. The drawing causes structural anisotropy that results in an elongation of grains along the axis of drawing. There was also an increase in electrical resistivity and in hardness following the deformation level increases. After annealing at 260C of the drawn wire, it was found a gradual return of the mechanical properties and microstructure to a state close to the state of as-received copper.

The paper presents the analysis of means of transportation used in the theoryand relations of resistance motion of wheel and full-track propellers. It is shown that the available scientific studies leave out singularities of deformation of soil at cyclical loadings by ground wheels. Presented relations of resistance motion of sprockets and reference ground wheels of a full-track propeller take into account a nature of soil deformation at repeated loadings. The decrease in contact stress is also taken in consideration at each subsequent loading. Rolling resistance of a reference ground wheel and overall resistance force of a rolling of a full-track propeller at different conditions of loading are defined.

Opis:
Introduction. The airborne transmission of infectious diseases in livestock production is increasingly receiving research attention. Reliable techniques of air sampling are crucial to underpin the findings of such studies. This study evaluated the physical and biological efficiencies and detection limits of four samplers (Andersen 6-stage impactor, all-glass impinger “AGI-30”, OMNI-3000 and MD8 with gelatin filter) for collecting aerosols of infectious bursal disease virus (IBDV). Materials and Method. IBDV aerosols mixed with a physical tracer (uranine) were generated in an isolator, and then collected by the bioaerosol samplers. Samplers’ physical and biological efficiencies were derived based on the tracer concentration and the virus/tracer ratio, respectively. Detection limits for the samplers were estimated with the obtained efficiency data. Results. Physical efficiencies of the AGI-30 (96%) and the MD8 (100%) were significantly higher than that of the OMNI-3000 (60%). Biological efficiency of the OMNI-3000 (23%) was significantly lower than 100% (P < 0.01), indicating inactivation of airborne virus during sampling. The AGI-30, the Andersen impactor and the MD8 did not significantly inactivate virus during sampling. The 2-min detection limits of the samplers on airborne IBDV were 4.1 log10 50% egg infective dose (EID50) m-3 for the Andersen impactor, 3.3 log10 EID50 m-3 for the AGI-30, 2.5 log10 EID50 m-3 for the OMNI-3000, and 2.9 log10 EID50 m-3 for the MD8. The mean half-life of IBDV aerosolized at 20 °C and 70% was 11.9 min. Conclusion. Efficiencies of different samplers vary. Despite its relatively low sampling efficiency, the OMNI-3000 is suitable for use in environments with low viral concentrations because its high flow rate gives a low detection limit. With the 4 samplers investigated, negative air samples cannot guarantee virus-free aerial environments, which means that transmission of infectious agents between farms may still occur even when no virus has been detected.

Opis:
Fleas are highly specialized holometabolic insects. So far, only 16 species of fossil fleas in five families have been reported due to the rare fossil records. At present, the earliest flea fossils are reported from the Middle Jurassic Jiulongshan Formation of Northeastern China. The descriptions of these earliest species pushed back the origin of Siphonaptera by at least 40 million years. It is generally accepted that saurophthirids are the “transitional” taxa from stem Jurassic fleas to living crown groups. Herein, we described a new “transitional” flea species, Saurophthirus laevigatus Zhang, Shih, Rasnitsyn, and Gao sp. nov., from the Lower Cretaceous Yixian Formation of Northeastern China, assigned to Saurophthiridae. The new species provides new evidence to support saurophthirids as a “transitional” group. Sexual dimorphism suggests significant differences in biology of opposite sexes in Saurophthirus. Analysis of described Mesozoic species demonstrates the body size reduction from the Middle Jurassic to the Early Cretaceous. Smaller body size was likely advantageous in reducing the probability of being detected and removed by the host and in minimizing flea’s demand for blood intake and energy input, indicating the adaptation of the ectoparasitic lifestyle of fleas in their early stage of evolution.

The paper presents principal approaches to diagnosing the structure forming skeleton of the complex optical field. An analysis of optical field singularity algorithms depending on intensity discretization and image resolution has been carried out. An optimal approach is chosen, which allows to bring much closer the solution of the phase problem of localization of speckle-field special points. A possible approach to diagnosing the signs of zero amplitudes has been offered.

Opis:
The use of a "window" 2D Hilbert transform for the reconstruction of the phase distribution of the intensity of a speckle field is proposed. It is shown that the advantage of this approach consists in the invariance of a phase map to a change of the position of the kernel of transformation and in the possibility to reconstruct the structure-forming elements of the skeleton of an optical field, including singular points and saddle points. We demonstrate the possibility to reconstruct the equi-phase lines within a narrow confidence interval, and introduce an additional algorithm for solving the phase problem for random 2D intensity distributions.

Opis:
Eco-friendly leather processes based on the usage of natural products have become a potentially attractive issue for leather industry during the last few decades. Synthetic protective chemicals like bactericides used in most soaking process are known as hazardous substances and cause tannery effluents with high concentrations of Chemical Oxygen Demand (COD). In the present study, the effect of tannic acid on microorganisms, skin, wool and effluent were investigated in order to demonstrate the applicability of tannic acid in soaking process instead of commonly used bactericides. The bacterial load (cfu/ml), COD and Nitrogen Content (N) of the soaking effluents and Total Kjeldahl Nitrogen (TKN) content of skins and wools were investigated. Application of 0.5 and 1 wt% tannic acid concentrations was more effective than commercial bactericide, while comparable results were achieved by 0.1 and 0.3 wt% tannic acid. The application of tannic acid for soaking process resulted in lower COD and N values of effluents. The results show that tannic acid has the potential to be an alternative, eco-friendly bactericide for leather industry by reducing the pollution of leather soaking process.
