We examine whether there is any movement in the employment of native-educated nurses due to the influx of foreign-educated nurses. To avoid conflating the short- and long-term reactions to the entry of newly arrived foreign-educated nurses, we implement a multiple instrumentation procedure. We find that there is no significant effect of foreign-edu...

Over the last 30 years, researchers have disputed the mixed evidence of the effect of the minimum wage on teenage employment in the United States. Whenever the minimum wage has positive or no effects on employment, they appeal to monopsony models to explain their results. However, very few of these studies have empirically tested whether their resu...

The continuous demands for stringent environmental regulation and increased interests in the preservation of natural resources have motivated industries and research institutions to examine and consider alternative approaches on the use of renewable resources and waste by-products. This study was conducted using one of the most available natural fi...

Real water losses derived from water supply systems represent an important topic, nowadays. It is difficult to predict and to calculate the water lost volume, these values being crucial in any water balance. In addition, the leakage flow can be estimated only when the geometric and hydraulic characteristics of the pipes and the period of time assoc...

The work aim is to propose lighting system designs that would satisfy the broiler welfare in terms of intensity; wavelength; switching interval; and energy savings, and would help farmers to reduce the unit costs. BuildingDesign software with Wils 7.0.342 module was used to design suitable lighting, calculate and visualize it. By optimizing the req...

The aim of experiment was to analyse the structural transformations and changes in mechanical properties of K720 steel during heat treatment (quenching). Three types of cooling medium were selected. The heating parameters and subsequent delays at the recrystallisation temperature were the same for all samples and were observed in a laboratory furna...

The paper reports some methods to select the optimal number of neighbors and to use eigenfeatures for aerial point cloud classification. In the literature, the neighborhood selection is performed using different methods. In this paper, we propose an approach that uses the region growing algorithm. The input data is an aerial point cloud, part of th...

The paper provided presents a new design of two-disk wide-row coulter that ensures uniform distribution of seeds to an even bed at the furrow bottom, as well as preserving of optimal distances between the seeds. Seeds fall from the seed tube of coil sowing apparatus onto a metal distribution plate with staggeringly arranged metal pins, which distri...

Goal of this study was to investigate and evaluate an impact of two alternative fuels on smoke emissions in comparison to diesel fuel. This study observes three different combustion engine fuels: biodiesel produced by Meroco, Inc. Company (Alternative fuel I); biodiesel produced in factory situated in Sereď (Alternative fuel II); and conventional d...

This paper emphasises the analogous modelling of hardwood (acacia) pyrolysis. The impacts of physical characteristics of hardwood chips on the pyrolysis are examined through the conservation of biomass solid mass fraction. The ONORM standard chips of sizes ‘G30’ and ‘G50’ and their combination are individually tested in the pyrolysis reactor. In th...
