«Nolite extollere in altum cornu vestrum». Ipotesi sul campanile della chiesa della Santissima Annunziata di Messina
2022
This article addresses a series of hypothesis concerning the octagonal space indicated in Guarino Guarini’s drawings of the Church of the Santissima Annunziata in Messina in his Architettura Civile. The façade of the church was completed around 1660 by Guarino Guarini and presented a «prodigiously high» bell tower at the corner, which collapsed during the 1693 earthquake and was later rebuilt shorter. The entire church was destroyed during the 1908 earthquake. Guarini’s drawings published in his treatise suggest that there must have been an octagonal chapel with columns at the corners under the tower; perhaps it was the baptistery of the church. Alternatively, the octagon can be identified …
Formation of secondary carbonates and native sulphur in sulphate-rich Messinian strata, Sicily
2010
Abstract Microbially formed authigenic carbonates accompanied by native sulphur are present in the ‘Calcare Solfifero’ below a thick succession of gypsum deposited during the Messinian salinity crisis in Sicily. We sampled these carbonates and associated sulphur in five former sulphur mines to subject them to a detailed petrographic and geochemical study in order to explore their different modes of formation. Native sulphur formed in conjunction with microbial sulphate reduction, which is reflected in its depletion in 34S (δ34S values as low as − 2‰ vs. V-CDT) and an enrichment of 34S in the residual sulphate (δ34S values as high as + 61‰). The oxidation of organic matter by sulphate reduct…
Charakter publikacji ks. prałata Carla Ulitzki (1873–1953)
2017
Tekst stanowi charakterystykę dostępnych publikacji ks. prałata Carla Ulitzki (1873–1953) i stanowi przyczynek do poznania postaci oraz działalności proboszcza i działacza społecznego i politycznego, ale także wgląd w sytuację społeczną, polityczną i religijną na Górnym Śląsku w I połowie XX w. Teksty mają charakter popularnonaukowy i w większości zostały opublikowane na łamach ówczesnej prasy, dzięki czemu rozpowszechniały i popularyzowały myśl i zamierzenia autora. Dostępne teksty zasadniczo dotyczą trzech tematów: pisma z obszaru szeroko rozumianej religijności, teksty dotyczące zagadnień historycznych oraz publikacje z obszaru polityki, które stanowią najobszerniejszy dział.
Reduced membrane-bound alkaline phosphatase does not affect binding of Vip3Aa in a Heliothis virescens resistant colony
2020
The Vip3Aa insecticidal protein from Bacillus thuringiensis (Bt) is produced by specific transgenic corn and cotton varieties for efficient control of target lepidopteran pests. The main threat to this technology is the evolution of resistance in targeted insect pests and understanding the mechanistic basis of resistance is crucial to deploy the most appropriate strategies for resistance management. In this work, we tested whether alteration of membrane receptors in the insect midgut might explain the >

Genomics and Proteomics Analyses Revealed Novel Candidate Pesticidal Proteins in a Lepidopteran-Toxic Bacillus thuringiensis Strain
2020
Discovery and identification of novel insecticidal proteins in Bacillus thuringiensis (Bt) strains are of crucial importance for efficient biological control of pests and better management of insect resistance. In this study, the Bt strain KhF, toxic for Plodia interpunctella and Grapholita molesta larvae, underwent genomics and proteomics analyses to achieve a better understanding of the bases of its pathogenicity. The whole-genome sequencing results revealed that the KhF strain contained nine coding sequences with homologies to Bt insecticidal genes. The lepidopteran toxic mixture of spores and crystals of this Bt strain was subjected to liquid chromatography and tandem mass spectrometry …
Differences in the midgut proteolytic activity of twoHeliothis virescens strains, one susceptible and one resistant toBacillus thuringiensis toxins
1996
The development of resistance to Bacillus thuringiensis toxic proteins is a growing concern because it could threaten both conventional and gene transfer use of this environmentally safe biological insecticide. The most common mechanism of resistance involves changes in binding affinity of toxin receptors in the insect midgut membrane. This has not been the case in Heliothis virescens. We have investigated changes in midgut proteolytic activity as a possibility to explain the resistance observed in this insect species. We have developed an improvement of known methods to demonstrate proteolytic activity in crude extracts. Using this method we have found differences in the proteolytic activi…
Hemocytes of Rhynchophorus ferrugineus (Olivier)(Coleoptera: Curculionidae) and their response to Saccharomyces cerevisiae and Bacillus thuringiensis
2011
Originally from tropical Asia, the Red Palm Weevil (RPW Rhynchophorus ferrugineus (Olivier) is the most dangerous and deadly pest of many palm trees, and there have been reports of its recent detection in France, Greece and Italy. At present, emphasis is on the development of integrated pest management based on biological control rather than on chemical insecticides, however the success of both systems is often insufficient. In this regard, RPW appears to be one pest that is very difficult to control. Thus inves- tigations into the natural defences of this curculionid are advisable. RPW hemocytes, the main immuno- competent cells in the insect, are described for the first time. We identifie…
The Judicial and Canonical Situation of the Romanian Byzantine Catholics in Hungary Around 1900
2021
This chapter analyses the legal and canonical situation of the Romanian Byzantine Catholics in Hungary at the end of the nineteenth century and the beginning of the twentieth century. Being part of the Hungarian State, the Greek Catholic bishops were subjected to the Hungarian hierarchy, attending the congresses and conferences of the Roman Catholic Bishops of Hungary. In addition, they were loyal to the Holy See, favouring the Latinisation of the Church in the three provincial councils. Through this approach, they secured the support of the papacy in disputes with the Hungarian higher clergy. Thus, they were able to uphold the individuality of their own Romanian Church, by organising their…
Engagement of the periesophageal ring during Holothuria polii response to erythrocyte injection.
2009
In Holothuria polii, the periesophageal ring is an important organ supplying spherule cells after stimulation with foreign material. In animals injected with formalinized sheep erythrocytes, in fact, a depletion of spherule cells is observed in the periesophageal ring, whereas in the connective tissue, in the external epithelium and around the antigen- injected site, small, transparent cells can be visualized. It is supposed that the latter are stem cells of spherule cells.
