Abstract

The results of investigations into suspended matter sedimentation from mine waters in the settling tank at the Ziemowit coal mine as well as in the relevant model of the settling tank were presented. It was shown that variations in the performance of the tank are caused by improperly accumulated sediment, which generates privileged water flow in superficial layers. Additionally, impetuous periodical water discharges seem to be important. The investigations performed on the settling tank model were focused on estimating the influence of temperature, flow rate and the aeration of mine water on the suspended matter sedimentation. Reasons for inefficiency of the settling tank were determined, and technological changes enhancing the process of suspensions removal were suggested.

Abstract

Nickel slag has a high-content iron and is a secondary utilization resource with great development potential. The coal-based direct reduction is an innovative technology that can be used to utilize the iron resources in nickel slag. The effect of the particle size of nickel slag on the strength and the reduction of nickel slag-coal composite briquettes were investigated. Four samples with particle size of 75~106 μm, 106~150 μm, 150~270 μm, and >270 μm were selected. The drop strength increased 9.4 times and the compressive strength reached 281.1 N when the nickel slag particle size decreased from >270 μm to 75~106 μm. The reduction degree determined by the data from the thermogravimetric experiment indicated that its maximum was 79.545%. The reduction experiments performed at 1200°C for 45 minutes indicated that the nickel slag with particle sizes between 75~106 µm were appropriate for the reduction of the nickel slag-coal composite briquettes.

Abstract

This experiment aimed to determine the effect of adaptive duration to saline water on behaviors, weight gain and blood biochemical parameters in growing goats. The experiment was arranged in a completely randomized design, which included four treatments with five animals per group. The goats were administered either fresh water (control) or seawater with a salinity of 1.5%, with varying durations of adaptation to seawater. The adaptive durations included an abrupt change (A0) from fresh water to seawater with a salinity of 1.5% or stepwise adaptation either 4 (A4) or 7 (A7) days of increasing saline concentrations. The results showed that dry matter intake in the non-adapted goats (A0 group) was lower than that of the control group or the adapted goats throughout the experiment (p<0.05). In contrast, water intake from drinking saline water was greater than that in the control group (p<0.05). Body weigh did not differ among the treatments; however, non-adapted goats exhibited a lower weight gain than the adapted goats (p<0.05). The goats in the A0 and A4 groups exhibited increased plasma levels of urea, AST, and ALT compared with the control and A7 groups. However, blood electrolyte levels remained unchanged and were within the normal range for goats. Therefore, it is concluded that the stepwise adaptation to seawater with a salinity of 1.5% for 21 days has no influence on productivity and health status of goats.

Abstract

When Zamość was being built the Fortress was in a close connection with the geometry of view. This was reflected both in the utilitarian and aesthetic sphere and concerned the urban scale as well as the scale of long exposure. The visual study conducted within the Study of the shaping of postfortress areas of Zamość Fortress allowed for assessing the contemporary state of exposure and for identification of the correction opportunities. The effect of the study has become the essential element of the design concept in both the compositional and in the part related to the tourist access.
