There are currently various styles of management being used to secure smooth and continuous planning and construction of new plants for processing of raw materials. One of the styles, which is economically effective, and at the same time ensures maintaining a high quality within the required time is project management which is also most frequently used. However, even when using this style of management it is essential to anticipate emergency situations that may arise due to various unexpected complications during the construction process. Nowadays, project management is considered to be the key that contributes towards better working practices in most companies. Since 2012 mobile SW applications have been on the increase and this has led to an increase in remote project management. Individuals and also companies can now manage their projects anytime and anywhere. This article deals with the use of the modern tool for project management - Microsoft Project. This SW is used for successful planning, implementation and control of designing conveyors for new plants which will be used in individual manufacturing processes mainly in the field of mining, processing of mineral materials, fuels and power, waste treatment, building, as well as food processing and agriculture. Microsoft Project allows early detection of problems and it also provides alternative solutions and measures during planning, implementation of installation and operation of these machines.

Possibilities of edible insects use in European countries, are now an increasingly debated issue. Insects in Asian, African, Central American and South Central American cultures are mainly nutritional components. This review mainly describes the species of insects that are suitable as food in Europe and other developed countries. This comprehensive work addresses the issue of eating insects, especially considering the nutritionally important factors. Risks are also mentioned, as well as allergies, toxicity, and other aspects of the breeding and use of edible insects. Insects play and will play important roles in the future in various fields of research, exploitation, breeding, etc. This review provides a comprehensive current and future view of insects as a valuable foodstuff. © by Jiri Mlcek 2014.

Since 2002, when the first lecture on entomophagy took place at Mendel University in Brno, till today, participants of these educational lectures were asked to fill questionnaires in order to evaluate interest in entomophagy in Czech Republic and pick suitable species. Analyses of nutritional value of selected species were also performed during this time. The questionnaire was divided into several parts - suitable species, sensory properties, difficulty of breeding and processing and respondents own attitude to the consumption of insect species. For the purpose of this study the questionnaire was evaluated using the semantic differential, so to create a comprehensive picture of each insect species. Based on evaluation of more than 5,000 questionnaires, certain developmental stages of seven species of insect were selected for further evaluation: Tenebrio molitor (TM) larvae, Zophobas morio (ZM) larvae, Gryllus assimillis (GA) nymphs, Locusta migratoria (LM) nymphs, Galleria mellonella (GM) larvae, Bombyx mori (BM) Pupa, Apis mellifera (AM) bee brood, while cockroaches were completely excluded for use in entomophagy. Although they are easy to breed and are available all year-round, consumers showed relatively great disgust. For all of these species, basic nutritional values were analysed, as well as content of amino acids and fattty acids. All parameters were statistically evaluated using ANOVA-1. Each species appears to be suitable for entomophagy for a different reason. Generally speaking, AM, TM and GA were best accepted considering the sensory aspect, nutritional values are interesting especially in BM and GM and TM wins with simplicity of its breeding.

Multivariate time series forecasting is applied in a wide range of economic activities related to regional competitiveness and is the basis of almost all macroeconomic analysis. In this paper we combine multivariate density forecasts of GDP growth, inflation and real interest rates from four various models, two type of Bayesian vector autoregression (BVAR) models, a New Keynesian dynamic stochastic general equilibrium (DSGE) model of small open economy and DSGE-VAR model. The performance of models is identified using historical dates including domestic economy and foreign economy, which is represented by countries of the Eurozone. Because forecast accuracy of observed models are different, the weighting scheme based on the predictive likelihood, the trace of past MSE matrix, model ranks are used to combine the models. The equal-weight scheme is used as a simple combination scheme. The results show that optimally combined densities are comparable to the best individual models.

This article is directed to evaluating the proportion of polycyclic aromatic hydrocarbons (PAHs) captured on particulate matter (PM) classified as PM2.5-10 and PM2.5, i.e. particulate matter of aerodynamic diameter 2.5-10 μm and 2.5 μm. During three week-long and one 2-day campaigns, 22 paired air samples were taken in parallel of PM10 and PM2.5 fractions inside the Mrázovka tunnel in Prague, Czech Republic. Following sample preparation, concentrations of individual PAHs were determined using gas chromatography combined with mass spectrometry. Concentrations of individual pairs of each PAH were tested by the nonparametric method using Spearman's rank correlation coefficient. At significance level p < 0.01, it was demonstrated that all individual PAHs, including their totals, were bound to the PM2.5 fraction. Exceptions were seen in the cases of acenaphthylene, acenaphthene, and indeno[1,2,3-cd]pyrene, the concentrations of which fluctuated around the detection limit, where increased measurement error can be expected. © 2015 Elsevier Ltd.

The phenolic compound composition, antioxidant activity and impact on cell viability of edible flower extracts of Allium schoenoprasum; Bellis perennis; Cichorium intybus; Rumex acetosa; Salvia pratensis; Sambucus nigra; Taraxacum officinale; Tragopogon pratensis; Trifolium repens and Viola arvensis was examined for the first time. Total phenolic content of the flowers of these plants fell between 11.72 and 42.74 mg of tannin equivalents/kg of dry matter. Antioxidant activity ranged from 35.56 to 71.62 g of ascorbic acid equivalents/kg of dry matter. Using the Human Hepatocellular Carcinoma cell-line (HepG2) and the Human Immortalized Non-tumorigenic Keratinocyte cell line (HaCaT), we assessed cell viability following a 3 day incubation period in media containing 25, 50, 75 and 100 μg/ml of total phenolic compounds using a colorimetric MTT assay. These three properties could make the herbs useful in treatment of various diseases like cancer. The tested extracts had significant effects on cell viability, but the effects were dependent not only on the phenolic compound concentration and the edible flowers species, but also on the phenolic compound and antioxidant profiles. In addition, responses differed between cell lines. © 2013 Versita Warsaw and Springer-Verlag Wien.

The paper provides a new way to optimize the location of container depots. According to the environmental effect brought by the daily operation of depots, in the optimal model both cost and environmental constraints are taken into account. In order to assess the environmental effect caused by depots, an AHP model was used in the paper. Because of the environmental constraints are considered in the model, the decision of the location of depots can not be made just according to cost. In order to test the model, it is implemented to locate the depots around Qingdao port. © 2014 IEEE.

The ecological footprint demand and ecological capacity for the six types of productive land during 2005~2010 are calculated using the ecological footprint model in this paper by taking Dongying City as the example, and the ecological deficit of Dongying City is thereby figured out. Based on this, the indicators such as the ecological footprint of 10k yuan GDP, the ecological pressure index, the ecological diversity index, and the social economic development index, etc representing the sustainable development are calculated and analyzed, to learn that it is not allowed to be optimistic about the ecological environment in Dongying in recent years, as the ecological deficit has increased year after year, and the ecological pressure has become heavier and heavier. However, it is learned through analysis of the ecological footprint of 10k yuan GDP and the social economic development index that under the situation when the ecological pressure on economic growth in the ecological economic system of Dongying is increased, a tendency exists for the consumptive and extensive economic growth pattern to gradually step towards the ecologically intensive pattern, but it is still required to make more efforts in the aspects of reducing the ecological footprint demand and improving the ecological capacity. © (2013) Trans Tech Publications, Switzerland.

Observation is the foundation of learning, recognizing the outside world, the basis for the thought processes and ultimately the basis for scientific thinking. The observation is based on the major sense - sight, which gives the most information to a man. Scientific observation has its own rules and laws. Its quality is dependent on the quality of the observer. The quality of the observer also determines the quality of visual observers, observer qualification, the terms of surveillance and other internal and external environmental factors and subject observation. Scientific observation must be seen as a qualification. Presented study deals about 6 steps of observation planning, 4 types of observers, and two types of observations. It presents the results of long term so called historical observation in the recreation area Donovaly in Slovakia. © SGEM2015.
