Herbicidal Derivatives of Aminomethylenebisphosphonic Acid. Part IV. Hydroxyalkylidenebisphosphonates, Iminomethylenebisphosphonates and Ureidomethyl…

2000

Derivatives of aminomethylenebisphosphonic acids constitute a class of promising herbicides. Replacement of the amino group by hydroxyl, ureido, thioureido, or imino moieties leads to compounds of significant herbicidal properties. This indicates that protonated amino function is not a requirement for phytotoxic action of bisphosphonates.

Variability in inorganic and organic nitrogen uptake associated with riverine nutrient input in the Gulf of Riga, Baltic Sea

2001

Concentrations and rates of uptake of dissolved organic nitrogen (DON, free amino acids, and urea) and inorganic nitrogen (DIN, nitrate, and ammonium) were measured along two transects in the Gulf of Riga, a sub-basin of the Baltic Sea, during May and July 1996. Concentrations of total dissolved nitrogen (TDN) were 23±3 μg-at N 1−1 in the northern region (mouth) and 41±5 μg-at N 1−1 in the southern region (head) of the Gulf. Rates of nitrogen uptake, determined with15N-labeled substrates, reflected differences in TDN concentration between the regions. In May, uptake of DIN+DON measured 0.17 and 0.43 μg-at N 1−1 h−1 in the northern and southern parts of the Gulf, respectively. In July, DIN+D…

Infrastrutture e paesaggio nella "città in estensione"

2017

L’esperienza didattica e di ricerca presentata nel saggio prende le mosse dall’attivazione di un laboratorio di laurea magistrale in Progettazione Architettonica diretto dal prof. Palazzotto e sviluppato nell’ambito del corso di laurea in Architettura dell’omonimo Dipartimento presso l’Università degli Studi di Palermo. Il laboratorio ha visto la partecipazione complessiva di 11 laureandi, che hanno esitato le proprie tesi negli anni compresi tra il 2013 e il 2015. Il laboratorio di laurea, facendo propria l’idea di “città-campagna” avanzata da Giuseppe Samonà nel 1976 – che porta con sé un esplicito riferimento a identità formali e spaziali specifiche intese a conferire allʼambito della ca…

An easy access to fused chromanones via rhodium catalyzed oxidative coupling of salicylaldehydes with heterobicyclic olefins

2016

Abstract Herein we describe a detailed study on the rhodium catalyzed oxidative coupling of salicylaldehydes with heterobicyclic olefins such as diazabicyclic olefins and urea-derived bicyclic olefins. The developed method provides an ideal route to fused chromanone systems in a single synthetic step. Moreover, the scope of this methodology was extended to different oxa/aza-bridged bicyclic urea derivatives.

Miarkowanie kary umownej w ramach powództwa o jej zwrot – glosa do wyroku Sądu Okręgowego w Olsztynie z 5.12.2018 r., IX Ca 758/18

2023

Komentowane orzeczenie dotyczy możliwości miarkowania kary umownej po tym, jak została ona zapłacona przez dłużnika z zastrzeżeniem zwrotu. Główny problem w sprawie stanowiło to, czy powód może skutecznie wystąpić z odrębnym powództwem o zwrot części zapłaconej już pozwanemu kary. Istota postępowania sprowadzała się do określenia formy i momentu wystąpienia przez dłużnika z żądaniem miarkowania kary umownej. Sąd zgodził się z tezą, że do miarkowania może dojść na skutek powództwa wytoczonego przez dłużnika. Natomiast przyjął kontrowersyjne stanowisko, które zostało poddane w niniejszej glosie krytyce, że do miarkowania nie może dojść po tym, jak kara została zapłacona

Nursing students' perceptions of combining hands-on simulation with simulated patients and a serious game in preparing for clinical placement in home…

2021

Abstract Background There is a growing demand to provide complex healthcare services in patients' own homes. However, high quality home healthcare clinical placements are often difficult to obtain, and arranging laboratory-based simulations to provide relevant clinical-practical learning experiences for all students is resource intensive. Objectives The aim of this study was to explore nursing students' perceptions of using a blended simulation approach, including hands-on simulation with simulated patients and a video-based serious game, in preparation for their home healthcare clinical placements. Design An exploratory qualitative design using focus group interviews was utilized. Setting …

The problem of welfare: Is there a welfare civilization?

1990

Abstract Welfare policy is at present increasingly tied both to market forces and to primary social networks. This process splits society into two camps. One‐fifth of the population is segregated from the rest in its dependence on the welfare system, which is in turn dependent on a diminishing portion of the economy and required to rationalize itself in terms of market forces. Meanwhile, the welfare system is making an effort to minimize its social cost by decentralization and by utilizing community ties and lifestyles rather than relying on the professional welfare bureaucracy. This process tends to combine modern forms of production with the meanings and values of traditional society. It …
