В статье освещено анатомическое строение стеблей омелы, пути ее проникновения в растение-хозяина. Показано анатомические особенности строения листьев омелы, установлено наличие в них кристаллов друзов, установлено количество проводящих пучков. Показано отсутствие дифференциации паренхимы на столбчатую и губчатую. Отмечено что густории омелы также содержат хлорофилл. Показано дифференциацию гаусторий, их разветвления и способ проникновения в древесину. Показано образования складок на коре растения-хозяина, когда прорастают семена или гаустории омелы. Также исследовано стебель омелы, показано расположение проводящих пучков, а также образование защитных модификаций растения-хозяина при повреждении полупаразитом. Был осуществлен анализ на содержание хлорофиллов в Viscum album на разных растениях-хозяевах, и проведено количественное сравнение параметров листьев Viscum album на разных растениях-хозяевах.

The concept of the personalized portion is associated with the amount of food adapted to each person and their needs, the proposal is based on the integration of work environment of companies that collaborate with the contract catering sector. The key points to act and implement in the companies are: the implementation of the nutrition appointments; the development of the database with the information of each employee; the translation of this information for the distribution in macronutrients and grams that, finally, are converted from the image of the employee’s "dish" of simple and fast interpretation.

The modern dewaxing process using endogenous wax ester hydrolyses (wax desynthetase) activation in optimal reaction conditions provides an efficient, specific and targeted affinity destructuration process orientated towards the wax substrate in order to develop the depparafinage effect. The lipase W/O interfacial activation was studied in the lipolyse and interesterification process but the endogenous O/S dewaesterase activation was until now non-investigated. The isoparaffins structures formation improves the dewaxing yield at 90.7% reported on the miscella crude oil with 270 ppm waxes content with an almost double-cold dewaxed oil stability. The present modern dewaxing technology eliminates the low-efficiency cold/low temperature crystallisation and all the negative effects given by the solvent oil recovery from the kieselgur pomace, cooling agent producing and separation by filtration/centrifugation process.

This paper presents a methodology that quantifies the life cycle costs of concrete decks of roadway bridges that supports the decision-making regarding the optimal selection between several construction / repair alternatives. A deterioration model based on the main material and environmental characteristics of bridges is presented. Some of the most up-to-date materials that are used on concrete bridges are also presented and characterized. The quantification of the user costs is presented. These calculations are made considering the vehicle operating costs, the cost of time and accident costs. The user costs are determined by comparing the traffic costs under free flow conditions with those that arise from disrupting the free traffic flow. The created model is applied to an existing bridge, where the determination and comparison of the costs of the application of different repair alternatives are analysed. At the end, the main conclusions and recommendations are presented.

The article describes newly created private firms are those that have been private since they were established, i.e. the enterprises, which were established after the transition process started. In the economic literature, they are also referred as de novo enterprises or firms. The paper reports new and unique firm level survey evidence to investigate the micro economic nature of the growth process and structural change in CIS countries. In particular, we investigate gross job creation and destruction in newly established private (de novo) firms and “traditional” ones, being state owned and privatized firms and find that the de novo private firms are the most dynamic ones in terms of job creation. As result of the research we find that state owned enterprises are not significantly different in their employment behavior from privatized firms, where mixed effects of competition on employment growth. Therefore, the result could be evidence that suggests efficiency wage payments are important for employment growth in couple of CIS countries.

The objective of this work is to analyze the possibilities of reusing plastic waste of cables added in a plaster matrix. Firstly, the experimental process has allowed the physicochemical characterization of the raw material, plaster and plastic waste, consisting in elemental analysis, XRD and thermogravimetric analysis; Secondly, the performance of physicomechanical tests of the mixtures, Shore C hardness, absorption and resistance to flexion and compression. During the investigation, the water/plaster ratio of 0.8 was maintained, as well as the grain size of the plastic waste as it comes from the recycling factory (maximum 3 mm). On the contrary, the amount of added plastic waste has oscillated up to incorporate 50%, 60% and 70% over the weight of the plaster. In comparison to a reference sample, the obtained compounds are characterized by having a higher Shore C hardness, a lower absorption by capillarity and a decrease in their values of mechanical resistance. The addition of plastic waste to a plaster matrix can be considered as a possibility to obtain compounds of greater sustainability to be used in the field of sustainable construction.
