title: High temperature linear impedance of 35P2O5-30Fe2O3-27.5Nb2O5-7.5TiO2

description: The high temperature electrical properties of phosphate-iron glasses containing niobium were investigated. Glass samples of the composition of 35P2O5-30Fe2O3-27.5Nb2O5-7.5TiO2 (in %mol) were prepared by the conventional melt quenching technique. Appropriate amounts of reagents ((NH4)2HPO4 (≥99.9%, POCH), Fe2O3 (≥99.9%, POCH), Nb2O5 (≥99.9%, PLUKA AG) and TiO2 (≥99.9%, anatase and rutile mixed, PROLABO)) were thoroughly mixed in an agate mortar and put on electric stove in temperature of 573K in order to carry out the decomposition process of (NH4)2HPO4. Next powders were melted in porcelain crucibles at 1573 K for 1-2 h. The melts were poured on preheated (to 573 K) brass plate and pressed by another plate to obtain flat circular samples (dimensions: 1-2 mm thick, 20-30 mm in diameter). The obtained pellets were annealed at 673 K for 1 h and cooled with furnace. For the electrical measurements gold electrodes were evaporated at the polished samples. Impedance measurements were carried out in the frequency range from 1 mHz to 1 MHz with the ac voltage of 1 Vrms in the temperature range from 363 K to 723 K with the Novocontrol Concept 40 broadband dielectric spectrometer and a high temperature Controller Novotherm HT 1600. The measurements were carried out both while increasing and decreasing the temperature.

title: Maximum temperature of 0.5-W infrared laser-Illuminated gold nanorod platforms

description: Data concern a system consisted of two pieces of borosilicate glass surrounded by air and joined together by a transparent glue, which is to serve as a thermal transducer. On the top and bottom sides of the smaller piece, gold nanorods are dislocated. Glass is prepared here due to its high transparency, facilitating heat to be produced within the system. On the top of the glassy domain (4), where the gold nanorods are dislocated, parallel laser beams are directed. Due to the large distance between them, some light penetrates the top and reaches the second, bottom gold surface. Results concern time responses of maximum temperature 5 μm above and 5 μm under glassy domain  of the AuNRs platforms. Platforms are subjected to a 0.5-W infrared laser illumination during 70 seconds.

title: DataSet Investigations into the quality of urban stormwater outflow as an alternative water source: potential for landscape irrigation reuse

description: Investigations into the quality of urban stormwater outflow as an alternative water source: potential for landscape irrigation reuse 
The pressure on the world’s water resources is increasing due to population growth and climatic changes. Valorization of stormwater as a water resource for non-potable reuse will reduce high-quality water demands and save it for potable uses. In this context, not only roof runoff but also drained stormwater outflow, representing considerably higher pollution levels, should be considered for reuse. We analysed the quality of stormwater from the municipal separate sewer system in a residential catchment located in a medium-sized town in Poland, in the context of reuse for landscape irrigation. The changes in concentrations of TSS, COD, BOD5, and Escherichia coli with rainfall duration were assessed during 6 torrential rainfalls (intensity over 15 L/s·ha). The concentrations of pollutants in the “first flush” were between: 93 - 1598 mg/L (TSS), 112 - 815 mg O2/L (COD), 7 - 30 mg O2/L (BOD5) and significantly dropped with rainfall duration. The E.coli number fluctuated from 2.5·103 to 5.3·105 MPN/100 mL. Rapid filtration on sand filters was applied in laboratory-scale for raw stormwater, providing treatment efficiencies of 87-88% for COD, 50-90% for TN, and 88-96% for TP. The quality of raw and treated stormwater was discussed with regard to the existing and developing European standards for water reuse. The results from our study show that treated stormwater outflows can be applied for landscape irrigation. Moreover, rapid filtration is appropriate for stormwater treatment and can be applied either with the support of pre-sedimentation or as the only separation process.

title: The experimental results of  diesel fuel spray with marine engine injector

description: The data set presents the measurement of the diesel fuel spray from with marine engine injector. The main target presents results is a study of the time course of macro parameters (spray tip penetration, spray cone angle) of fuel spray in the cylinder of marine diesel engine. The impact of ambient conditions and the geometrical parameters of the injector on the macrostructural parameters of the fuel spray was considered. The injector used is a conventional pressure-opened diesel injector from a Sulzer Al 25/30 type marine engine equipped with a Unit Pump injection system. The fuel was injected into a constant volume chamber providing an optical access. The injector was located at the top of the chamber. This setup allows observing the evolution of a single fuel jet at a distance of almost 100 mm (half of the cylinder bore).
The injection process was tested for three different nozzle diameters 0.285 mm, 0.325 mm and 0.375 mm corresponding to L/D ratio 10.9, 9.5 and 8.3. The shape nozzle was cylindricaland K factor was 1.  The fuel pressure in the common rail system was 50 MPa. The injector opening pressure was adjusted to 15 MPa, 25 MPa, 35 MPa. The backpressures was 3.2 MPa and 4.3 MPa in constant volume chamber, corresponding to half- and full-load engine operation. Inside constant volume chamber was nitrogen.  The sprays inside the chamber were visualized by means of the Mie scattering method. Two externally located halogen lights (0.5 kW each) were use to light sheet illumination of fuel spray. The illuminated sprays were observed by a Photron SA1.1 high-speed camera. The resolution of the recorded images was 512 × 256 pixels. One pixel is equal to 0.13 mm in this study. The images were recorded at a frequency of 40 kHz.The marine injector was fueled by diesel oil at a constant temperature through the common rail system. The pressure behind the injector was measured by means of a Kistler type 4067E piezorezistive pressure sensor.  The measurement was repeated three times at each point.

title: EH36 steel for shipbuilding - fracture documentation for CTOD test (plate thicnkness 50mm), a0/W = 0.5

description: The basic method of ductility designation of structural steels is the Charpy impact test. The test consists of a single strike of the specimen using a Charpy pendulum. Its result is the value of work necessary to break a specimen at a test temperature. Despite its many advantages, such as its short implementation time and low costs, it has its disadvantages, in particular:
• strong influence of notch geometry on the test result, which means that impact strength cannot be considered as an unambiguous material property,
• milled notches are not repeatable because the cutter wears,
• regardless of the thickness of the material being tested, samples of the same size are used.
Due to these disadvantages, for very responsible ship and ocean engineering constructions, such as: continuous longitudinal coamings of the largest container ships, or supporting components of drilling platforms, tests are carried out basing on fracture mechanics. For shipbuilding industry, CTOD (Crack Tip Opening Displacement) is, the most often, desired value. The test CTOD is performed by slowly bending the specimen with record of the slit opening. Before performing the test, it is necessary to know the material properties (from a tensile test). The final stage of the test is the measurement of the initial fatigue fracture geometry.
The dataset contains the photographic documentation of fracture and measurement of fatigue precrack for a0/W = 0.50 specimen.

A total of 10 sites were evaluated, 7 within Chalhuani and 3 within Tambojarkas. In each site, three 30-meter linear transects were established, oriented to the north, southeast, and southwest. Along each transect, characteristics related to grasses and vegetation cover in the area were assessed, ranging from areas with low cover (due to overgrazing) to areas with high vegetation cover (less impacted sites). To evaluate the diet and nutrients available to vicuñas in these areas, focal group monitoring was carried out, and fecal samples were collected from identified dung piles of these groups to determine the composition of plant species consumed by these individuals.
