This article presents the key elements in understanding the development and design of uniforms for the employees of the Customs Administration of the Republic of Slovenia for the purpose of corporate identity. It will show, in detail, the process from design to analysis of evaluation data for the multifunctional waterproof jacket, after three months of wearing by the employees. The success of a corporate uniform depends on how effectively it serves a specific function, makes the organisation recognisable in society and also on the satisfaction level of the user. The results are presented in four groups: First, the relationship between design and communicating identity for recognition in the market; Second, the determination of the pattern and functionality considerations; Third, the selection of materials and their properties; Last, the quality of workmanship, giving practical value to the above parameters.

Limestone powder characterized by hydrophobic properties is used as an anti-explosive agent in coal mining industry. Unfortunately, the standard method of producing such powder by milling limestone with stearic acid is practically unprofitable in many modernized quarries and plants, and sometimes literally impossible due to the introduction of technological changes and implementation of modern mills. Then new methods of hydrophobization of limestone surfaces ought be searched. In the work two methods hydrophobization: from the stearic acid vapour phase and from silicone solutions are proposed.
Lime dust from the Czatkowice Quarry of Lime was used as a raw material during investigations. It is a good agent for research because it is possible to compare the properties of samples modified in this work to the properties of anti-explosive lime powder (Polish Standard, 1994) used in mining industry in Poland.
The first technique of limestone powder hydrophobization was carried out in an apparatus of own design (Vogt, 2008, 2011), and it consisted in free sedimentation of the powder layer dispersed by stearic acid vapour in powder counter current flow. The second way of modification consisted in mixing in the evaporating dish substrates: limestone powder and dope - silicone solution - Sarsil® H-15 (Vogt & Opaliński, 2009; Vogt & Hołownia, 2010). Evaluation of properties so-obtained waterproof powders was carried out according to the Polish Standard, as well as using original powder determination ways, with the Powder Characteristic Tester (Index tables, Tablets & Capsules, 2005). Moreover water vapour adsorption isotherms were obtained and the thermal decomposition of powder was made. All modified samples acquired the hydrophobic character. Therefore we can state that the both proposed methods of hydrophobization of the limestone powder are useful. The parameters obtained with the use of Powder Characteristics Tester enable us to make a characterization of limestone properties not only as a water resistant material but also from the cohesion point of view. On the base of TG, DTG or DTA and EGA curves for all investigated materials was stated that the character of the thermal decomposition of modified samples is the same as this one for raw powder, what is profitable for application of hydrophobized powders as an anti-explosive agent.

Conducted research involved evaluation of selected soil properties in eggplant cultivation with the use of living mulches from white clover and perennial ryegrass. The mulching species were sown three weeks before eggplant planting, in the term of planting and three weeks after planting this vegetable. In half of August there was assessed stability of soil aggregates on the basis of the following indicators of: cloddiness (B), misting (S), structure (W) of the soil and mean weighed diameter of aggregates - the dry method (MWDa), as well as water stability ( MWD) and waterproof (Wod) index of soil aggregates and mean weighed diameter of aggregates - the wet method (MWDg). Cover plants did significantly decrease soil cloddiness indicator, while the earliest term of their sowing contributed to lowering of that parameter values by nearly 1/3 in relation to the data obtained for mechanically treated plots. Indicator of misting of the soil and soil structure index was higher for the soil of inter - rows covered with living mulches. It was noticed that longer term of covering inter - rows with white clover and perennial ryegrass improved soil structure. Living mulches improved mean weighed diameter of aggregates, determined according to the wet method, as well as indicator of aggregates waterproof and water stability index. After sowing white clover or perennial ryegrass three weeks before eggplant planting, mean weighed diameter of aggregates, measured with the use of the wet method, was higher by 29.0% and by 18.3% than the one characterizing the object with the last term of sowing and it was higher by 31.4% and 17.1% than the value determined for mechanically treated inter - rows. ΔMWD indicator for the soil covered with white clover and with perennial ryegrass was, average, by 15.5% and 34.7% higher than the data featuring mechanical treatment. For Wod index those differences amounted 18.8% and 9.7% respectively

Disposal sites for both industrial and communal waste are hazardous for the natural environment due to the accumulated materials and their chemical, physical and biological transformations. The products of these processes migrating at a significant distance contaminate mainly underground waters, surface waters and soils. The spreading of the pollutants may be prevented by horizons of clay rocks that form natural geological barriers. The clay rocks of properly selected parameters may be used in the environmental engineering for constructing artificial water-sealing layers. The mineral, chemical, physico-chemical and physico-mechanical properties of the beidellite clays occurring within the lignite deposit in Bełchatów were studied to find out whether they meet the criteria of waterproofing engineering contained in the Polish recommendations and instructions. The results indicate that the beidellite clays of Bełchatów are rocks suitable for this kind of environmental engineering and may be used in constructing the barriers preventing the migration of effluents from landfills.
