The occurrence of 12 selected pharmaceutical compounds and pharmaceutical compound metabolites in sewage treatment works (STW) effluents and surface waters was investigated. The substances selected for the monitoring programme were identified by a risk ranking procedure to identify those substances with the greatest potential to pose a risk to the aquatic environment. STW final effluent and sur...

The expansion of the settlement trough is an important factor in the risk assessment of the tunneling induced settlement. The increase of settlement trough requires buildings to be included in the impact zone, which causes damages. This paper conducts estimation of the settlement trough width (STW) using empirical approaches, field measurement data and numerical solutions. The credibility of th...

We study normalization of deterministic sequential top-down tree-to-word transducers (stws), that capture the class of deterministic top-down nested-word to word transducers. We identify the subclass of earliest stws (estws) that yield unique normal forms when minimized. The main result of this paper is an effective normalization procedure for stws. It consists of two stages: we first convert a...

Globally, the building industry has grown in last decades. Furthermore, new technological advances construction materials with high embodied energy have been widely introduced Latin American countries' architecture. Over decades, Ecuadorian Andean region experienced these changes. To analyze environmental impact of transformations, this research quantifies Specific Total Embodied Energy (STEE) ...

Purpose This paper aims to study the type of short-time work (STW) schemes implemented in Spain preserve jobs and workers’ incomes during COVID-19 crisis corresponding labour market outcomes. Design/methodology/approach A dynamic macroeconomic model job creation destruction search matching a dual market. Findings The shows that availability STW does not necessarily prevent large increase unempl...

Cosmogenic aluminum-26 and beryllium-10 burial dates of low-lying fossiliferous breccia in the caves at Sterkfontein, South Africa, show that associated hominid fossils accumulated in the Lower Pliocene. These dates indicate that the skeleton StW 573 and newly discovered specimens from Jacovec Cavern have much the same age: approximately 4 million years. These specimens are thus of an age simil...
