Importance of seeds in the process of common ragweed invasion
2012
International audience; Ambrosia artemisiifolia L. (common ragweed) was introduced into Europe at the end of the 1900s and is now present in several European countries. This annual invasive plant produces seeds that are highly polymorphic. Common ragweed can produce only a few thousand highly viable seeds. Many studies have focused on the seed stage. Greater seedling emergence for the seeds placed near the soil surface could explain the success of this species in open habitats, where the probability of deeper burial is low. Emergence percentage was found to decrease as burial depth increased from 2 to 8 cm, and no germination nor seedling emergence was observed for the seeds buried from 10-…
Weed seeds ability to emerge on the soil surface
2015
International audience; Annual weeds have to produce seeds each year to maintain their populations. These seeds fallon the soil surface. Seeds exposed to light during their moistening (i.e. caused by rain) bettergerminate than seeds in the darkness (i.e. buried). However, rare studies quantified the unique andcombined effects of light, moisture and burial depth on the germination process. We investigated,in a greenhouse experiment in 2014, the impact of seed moisture (Moistened vs. Dried), lightduring moistening (Darkness vs. Light) and burial depth (Buried vs. Surface) on germination of 12annual weed species contrasted on their seed traits and germination periods (Alopecurusmyosuroides Hud…
Investigation of sterols as potential biomarkers for the detection of pig (S. s. domesticus) decomposition fluid in soils
2012
This study was carried out to evaluate the potential of using cholesterol and coprostanol, as indicators for the detection of decomposition fluid of buried pigs (S. s. domesticus) in soils. In May 2007, four pig carcasses (~35. kg) were buried in shallow graves (~40. cm depth) at the University of Ontario Institute of Technology in Canada. Two pigs were exhumed after three months (Pig 1, Pig 2) and six months (Pig 3, Pig 4) post burial. Soil samples were collected beneath the pig carcasses (~40. cm depth) and from grave walls (~15-20. cm depth) as well as from a parallel control site. Coprostanol and cholesterol were extracted from soils, purified with solid phase extraction (SPE) and analy…
Nuovi dati sulla catacomba di Sabratha (Libia)
2016
La ricerca è stata condotta in collaborazione con Giuseppina Cipriano per la parte archeologica e Francesco Scirè per il rilievo topografico e diretto, nell’ambito del Progetto PRIN 2008 dal titolo: Pagani e cristiani a Sabratha e Leptis Magna tra III e VI secolo d.C. Monumenti e reperti, tradizione e immagini, coordinato da Rosa Maria Carra.La catacomba di Sabratha è uno dei pochi esempi di cimitero comunitario cristiano finora noti nell’Africa Romana. L’ingresso, lungo il tracciato del decumano minore proveniente dal complesso episcopale della Regio III, si trova a pochi metri dall’attuale linea di costa, a metà strada fra il grande santuario suburbano di Iside e l’Anfiteatro e nei pressi…

Badania archeologiczne na Ukrainie nad Dunajem w miejscowości Kartal/Orłowka
2020
Głównym celem artykułu jest przedstawienie badań archeologicznych z 2013 r. w miejscowości Kartal/Orłowka na Ukrainie. Badania dotyczyły odkrycia wielokulturowego kompleksu osadniczego i znajdującego się na nim cmentarzyska. Odkryte cmentarzysko związane jest z eneolitem i epoką brązu. Pochówki szkieletowe odkryte podczas wykopalisk ułożone były w pozycji embrionalnej (skurczone po prawej stronie, nogi podciągnięte pod klatkę piersiową), jeden z nich był podwójny. Przy pochówkach odnaleziono wyposażenie w postaci miski ceramicznej i małego glinianego naczynia. Kości ludzkie zachowane były w złym stanie, zostały uszkodzone przez czas, glebę i niewielką głębokość zalegania pochówku. Badacze r…
The ‘grave of the Court Pit’, A rediscovered Bronze Age tomb from Carchemish
2014
This paper examines the British Museum unpublished records related to an Early Bronze (EB) Age pithos burial uncovered a century ago in the Inner Town at Carchemish. The grave, cursorily cited and variously dated (Chalcolithic, EB or even LBA) in the final reports, was described in some detail by Hogarth and Thompson; a precise dating is, however, possible today thanks to the information of paramount importance given by T. E. Lawrence who identified and took a picture of the associated finds, which was recently rediscovered in the Carchemish Archives. The pithos can be now ascribed to the third quarter of the third millennium BC and helps to confirm the recent theory according to which the …
Le testament de Louis de Bourbon-Vendôme, évêque d’Avranches (1510)
2014
Fils légitimé d’un prince, évêque réformateur, mécène et humanisant, Louis de Bourbon-Vendôme laisse en 1510 un testament où il se montre peu soucieux de vénération des saints, de fondations perpétuelles et de legs charitables, assuré qu’il est de son propre salut par la grâce de sa consécration au point de constituer en autant de reliques les trois parties de son corps dont il a demandé le démembrement, tête, cœur et ossements. Legitimate son of a prince, reforming bishop, philanthropist and humanist, Louis de Bourbon-Vendôme left in 1510 a testament in which he shows little interest in veneration of saints, perpetual foundations and charitable bequests. However to assure his own salvation…
Wokół pochówku domniemanego weterana bitwy pod Byczyną w 1588 r. – studium archeologiczno-historyczne
2020
Byczyna is today a small city, located in the northern part of the Opolskie Voivodeship. This stronghold is famous for well-preserved city walls, as well as for its history, especially that associated with the memorable battle of 1588. Of course, here is the clash between the troops led by Jan Zamoyski (1542-1605) and Archduke Maximilian III of Habsburg (1558-1618), which ended in the defeat of the latter. This event had a great impact on the history of the Polish-Lithuanian Commonwealth, as it pushed the Habsburgs away from royal power, as well as consolidated the rule of the Vasa dynasty. The Battle of Byczyna was an armed clash in which a representative of different nations met – Poles, …
Influence of Calcium Carbonate Nanoparticles on the Soil Burial Degradation of Polybutyleneadipate-Co-Butylenetherephthalate Films.
2022
A polybutyleneadipate-co-butylenetherephthalate (PBAT) sample, commercially known as Ecoflex®, was processed via melt extrusion with CaCO3 nanoparticles coated with a hydrophobic coating. Blown films of PBAT and two composites with nanofiller (2% and 5%wt) were prepared and degradation tests in soil at 30 °C up to 180 days were carried out with weight loss measurements. Furthermore, biodegradation test according to ISO 14851 was carried out at 30 °C. The effect of CaCO3 on soil burial degradation was assessed by surface wettability and SEM. ATR-FTIR and XPS analyses highlighted chemical modifications induced by soil degradation. CaCO3 nanoparticles decreased surface wettability …
