Acute toxicity of toluene, hexane, xylene, and benzene to the rotifers Brachionus calyciflorus and Brachionus plicatilis.
1992
A large number of studies on the biological effects of oil pollution in the aquatic environment deal with the effects of whole crude or refined oils or their water-soluble fractions. However, low boiling, aromatic hydrocarbons, which are probably the most toxic constituents of oil, have until now not been examined in sufficient detail. Toluene, benzene and xylene, constitute a major component of various oils. They may be readily lost by weathering but are toxic in waters that are relatively stagnant and are chronically polluted. Korn et al. have stated that toluene is more toxic than many other hydrocarbons such as benzene, though the latter are more water-soluble. Report of the effects of …
Assessment of chronic effects of tebuconazole on survival, reproduction and growth of Daphnia magna after different exposure times
2015
The effect of the fungicide tebuconazole (0.41, 0.52, 0.71 and 1.14mg/L) on survival, reproduction and growth of Daphnia magna organisms was monitored using 14 and 21 days exposure tests. A third experiment was performed by exposing D. magna to the fungicide for 14 days followed by 7 days of recovery (14+7). In order to test fungicide effects on D. magna, parameters as survival, mean whole body length, mean total number of neonates per female, mean number of broods per female, mean brood size per female, time to first brood/reproduction and intrinsic rate of natural increase (r) were used. Reproduction was seriously affected by tebuconazole. All tebuconazole concentrations tested affected t…
Effects of tetradifon on Daphnia magna during chronic exposure and alterations in the toxicity to generations pre-exposed to the pesticide.
2000
Daphnia magna was exposed to some nominal sublethal tetradifon concentrations (0.10, 0.18, 0.22 and 0.44 mg/l) during 21 days. Chronic toxicity tests were carried out using neonates of F(1) first brood (F(1)-1st) and F(1) third brood (F(1)-3rd) offspring generations from parentals (F(0)) pre-exposed to the pesticide. The effect of tetradifon on survival, reproduction and growth was monitored for the selected daphnid generations. The parameters used to evaluate pesticide effect on reproduction were: mean total young per female, mean brood size, time to first reproduction, mean number broods per female and intrinsic rate of natural increase (r). Survival and growth (body length) were also det…

Las Cortes de 1443-1446 y la Hacienda de la villa de Alcoy
2004
By means of this work, we try to analyze how onerous were for the royal town's treasury the expenses derived from their attendance to Assemblies. For this, we are taking, as an example, the royal town of Alcoy in the <i>Cortes</i> of 1443. We have based our study in the <i>Proceso de Cortes</i> and in municipal sources.<br><br>Mediante este trabajo, pretendemos analizar el peso que tenían en la hacienda de las villas reales los gastos derivados de su asistencia a Cortes. Para ello tomaremos como ejemplo la villa de Alcoy en las Cortes de 1443-1446, basando nuestro análisis en el Proceso de Cortes y en fuentes municipales.
Las Cortes de Martín el Humano (1401-1407) y su repercusión en la Hacienda de la ciudad de Valencia.
2004
The general purpose of this paper is, towards municipal source knowledge, to study Treasury incidence of Cortes council, designed by King Martin of Aragon in the city of Valencia between 1401 and 1407. Cortes books of account register some files related to complaints about the <i>Cortes</i> meeting (embassies and aids to the king...), wages (receivers, notary public, bailiffs...), the <i>Cortes</i> development (documents copy and shipment, reading of <i>fueros</i> and other local laws...) and other expenses (city entrance party games, tips to royal officials...). Negotiation, approval and distribution of <i>Cortes</i> economical donation they …
Income and expenses of Jan Karol Chodkiewicz (1686–1712), starost of Veliuona, Zabłudów, Baisogala and Daugeliskis, relating to his schooling in Wars…
2021
Postać Jana Karola Chodkiewicza (1686–1712) z linii supraskiej nie doczekała się do tej pory swojego opracowania choćby w postaci noty biograficznej. Artykuł niniejszy przybliża więc wybrany fragment z życiorysu wyżej wymienionego bohatera, który w latach 1700–1705 przebywał na naukach w szkole jezuickiej w Warszawie. Okres nauk stanowił ważne wydarzenie w życiu młodych magnatów, którzy w ich ramach przygotowywali się do służby państwowej i funkcjonowania w społeczeństwie szlacheckim. Nie inaczej było w przypadku Jana Karola, dziedzica ogromnej fortuny chodkiewiczowskiej, który resztę swojego krótkiego życia spędził później na sporach o dobra ojczyste. Młody starosta pobierał nauki w trudny…
Comparison of effects on crustaceans: carbon nanoparticles and molybdenum compounds nanowires
2013
Carbon nanomaterials (CNM) and molybdenum compound nanostructures are materials with various applications yet little is known regarding the toxicity of these nanoparticles in pristine form in aquatic environment. Daphnia magna standard acute toxicity test (EN ISO 6341:1996; freshwater) and Artemia salina standard acute toxicity test (ArtoxKit standard method; 15 ppt saltwater) were applied to assess the toxicity of non-modified CNM and molybdenum compound nanowires in water. It has been observed that CNM are more toxic in freshwater suspensions and somewhat more toxic than the tested molybdenum compound nanowires.
Las Cortes de 1428 y su repercusión en la Hacienda municipal de la ciudad de Valencia
2004
Call for Cortes council means to Valencia's city big expenses about municipal Treasury. All of them were accounted by <i>clavario</i> of the city in his book of accounts (document wages, copy, donations, etc.). From these books, and also by the same ones written by the <i>Consell</i> (Valencia city council), we can know which expenses they were, and also how, from 1428, mostly percent of these expenses were assumed by <i>Diputation del General</i> (also known as <i>Generalitat</i>, Kingdom political and economic assembly).<br><br>La convocatoria para asistir a Cortes le suponía a la ciudad de Valencia toda una serie de gastos que r…
Jan Karol Chodkiewicz (1686–1712) – szkic biograficzny młodego magnata
2021
Artykuł stanowi próbę zaprezentowania postaci Jana Karola Chodkiewicza z linii supraskiej (1686–1712), syna starosty błudeńskiego i oboźnego wielkiego litewskiego Jerzego Karola Chodkiewicza oraz Marianny Tekli z Naruszewiczów, który do tej pory nie doczekał się żadnego szerszego opracowania naukowego. Podstawę źródłową szkicu biograficznego Chodkiewicza stanowią materiały przechowywane w Archiwum Narodowym w Krakowie, w zespole Archiwum Młynowskie Chodkiewiczów. Różnorodność znajdujących się w nim dokumentów pozwoliła na możliwie jak najdokładniejsze odtworzenie jego życiorysu. Z niego wyłania się postać Jana Karola, który osierocony przez ojca w dzieciństwie zdany był na opiekę swojej mat…
