Features of the fossil record of evolution

100%
Neither allopatric speciations nor extinctions of lineages are directly observable in the fossil record. This significantly reduces the value of inferred durations of taxa as a basis for studies on patterns of evolution. The ranges of taxa detected in rock strata are inevitably shorter than the real durations of lineages. Rates of evolution estimated by counting reported ranges of taxa therefore appear higher than they really were. Biometric studies of gradually evolving lineages indicate that the durations of ‘species’ (morphologies) were actually many times longer. Therefore, the ancestor-descendant relationships along monospecific lineages remain the most important subjects of study in evolutionary paleontology. A way, in which an ancestor-descendant hypothesis can be falsified, is presented.
This article presents the concept of the methodology for assessing the implementation of programmes of measures adopted in the State Water and Environmental Programme, and, in consequence, in the framework of the first water management plans for river basin districts in Poland, as approved by the Council of Ministers on 22nd February, 2011, and published in the official journals. The scope of work in the methodology concept primarily concerns two basic analyses: assessment of the accomplishment of programmes of measures with regard to the degree of their accomplishment, and assessment of the effectiveness of scheduled programmes of measures. The level of accomplishment should be understood as the quantitative status of progress of particular measures, whereas effectiveness means their direct or indirect impact on the achievement of environmental goals of the Water Framework Directive. For this purpose, for some of the measures databases and reports existing in institutions responsible for the performance of measures indicated in the SWEP were used. For the rest of the measures, the survey method was used. For the purpose of the surveying process, the preparation of appropriate matrixes with measures marked for institutions, and also of email address databases, were proposed. Also, identifiers serving to link answers with specific areas on maps that trace measures were proposed. The present and forecast situation concerning reporting in the scope of the WFD and other tasks connected with it in the field of environmental protection leads to the conclusion that the coordination of reporting at the state level and the improvement of the flow of information between interested institutions is necessary.
Constantly increasing demands for experimental modeling of engineering processes across the board helps fill a very powerful computer. Despite this fact, it is extremely important to find and verify the mathematical model, which actually corresponds to reality. This allows you to perform difficult analysis of observed values observed phenomenon. By this purpose, we need to design methodologies for modeling which is the aim of presented article.
The development and introduction of the integrated quality management systems were enhanced by the fact that in the different areas of the management of the enterprise processes several common properties can be found which can be defined in the same way and are common in all management systems. Integration means incorporation of different parts into a bigger unit or whole. Nowadays, the above mentioned explanation of integration means the unification of the management steps (financial, production, stock management) and the unification of the requirements written in different normative documents. ave the following properties: complexity, sensitivity, modularity, dynamics, professionalism, and profile-neutrality. The integrated system means a uniform management system that consists of two or more special management system standards, and a normative document. Thus, it is a system that consists of several management systems and system elements that helps the management of the enterprise to accomplish the tasks that belong to different management systems but can be included in a uniform management system.

The aim of this work was to investigate the possibility of using various electrical and dielectric parameters to distinguish natural honeys and determine their authenticity. Electrical properties of honey were tested at temperatures between 10°C and 30°C, in an electromagnetic field frequency ranging from 50 Hz to 20 kHz. The determination of permittivity, dielectric loss factor and conductivity for honey makes it possible to distinguish types of honey and check their authenticity. The temperature of a honey sample has a significant effect on the values obtained for the measured electrical properties. Testing should be carried out within a temperature range of 15°C to 25°C. Further research, carried out on a greater quantity and variety of honeys, may lead to the introduction of new effective methods for evaluating the type and quality of natural honey.
The aim of the study was the comparative analysis of the results of the phosphorus balance calculated by two methods, in the field scale and the farm scale, and assessment of usefulness of the application of balances in monitoring the agricultural production. Twenty-six large-scale farms were selected for studies with the area from 204.0 to 11391.5 ha. The analyses used data from the years 2002-2006. The spatial scope included the farms located in 33 municipalities, which administratively belonged to three provinces. Twenty six municipalities were located in 7 areas particularly nitrate vulnerable zones (NVZ’s). The evaluation of phosphorous load of the selected farms in different regions was performed based on the calculation of the balance with two methods – field surface and farm gate. As research has shown although the balance of the phosphorus calculated with the field surface method was on average higher by 7.2 kg P2O5·ha-1 AL, the results obtained based on two different methodical approaches indicate similar trends. The higher balance was mainly affected by manures produced in the own farm. Maximal values of the balance in both methods remained at a similar level, reaching approx. 60 kg P2O5·ha-1 AL. In case of the field surface balance, 7 farms fitted in the standard, and in case of the farm gate balance 5 met recommendations concerning the acceptable balance for the analysed region.
Subject and purpose of work: The aim of the study is to identify methodological problems, which may be encountered during the preparation of the energy balance of a territorial unit, along with indications of ways to solve them. Materials and methods: Problems were identified during the preparation of the energy balance for two selected rural communes and then they were investigated with reference to the literature on this subject. Results: Estimating the energy demand of a local government unit requires proper identification of the groups of energy consumers, divided into facilities owned or co-owned by communes and ones independent from commune authorities. The latter group is divided further, into households, businesses, farms. For each of the users different methods of obtaining data may be needed: a survey and analysis of statistical data, analysis of financial documents, evaluation of the buildings’ age. Generally, however, preparing an energy balance statement requires many simultaneous approaches, and the combination of multi-criterion analysis provides the most reliable picture of the problem. Conclusions: The scope of the data needed to compile an energy balance statement for local government units, depends on the purpose of the developed analysis. Methodological handbooks and training materials on this subject are helpful, but the developed methodologies may need to be modified and adapted to specific conditions.
