Brief an Garlieb H. Merkel
1799
Ms. 930a, Nr. 8, Bl. 22r-23v Böttiger, Karl August. Brief an Garlieb H. Merkel, Weimar, d[en] 13. November 1797 Autora rokraksts / Autograph, vācu, angļu un latīņu val. / Deutsch, Englisch und Latein [4] lpp. / S. Attēlu numuri / Bildnummern: 930a-008-1 – 930a-008-4 Der Verfasser nennt in diesem inhaltsreichen Brief zahlreiche Namen und hält nicht nur die Verbindung mit Merkel, die aus dessen erstem Aufenthalt in Weimar resultierte, aufrecht, sondern gibt ihm weitere Hinweise und Empfehlung für seinen weiteren Aufenthalt in Dänemark. So rät er zur Übersetzung dreier Romane aus dem Englischen, darunter Jane Wests „A gossip's story“ (London 1796). Ferner bittet der Verfasser Merkel um Gefälli…
The embryological development of the limbus and of the lateral and anterior wall of ductus cochlearis in the rabbit.

The landscape of strongholds
2016
La difesa dei territori ha offerto risultati straordinari alla formazione e alla trasformazione del territorio e del paesaggio, a volte con tratti spettacolari e dimensioni incredibili. La celebrazione del centenario dell’inizio della Prima guerra mondiale ha offerto lo spunto per una riflessione sulle ricadute indotte sul paesaggio dagli eventi bellici, e più in generale dalla realizzazione di strutture difensive e del loro rapporto con il paesaggio circostante. Territorial defence led to extraordinary results in terms of forming and transforming the territory and landscape, at times with spectacular sights and incredible sizes. The one hundred year anniversary since the beginning of the F…
Organic materials in the wall paintings in Pompei: a case study of Insuladel Centenario
2012
Abstract Background The present research concerns the Roman wall paintings preserved at Insula del Centenario (IX, 8), the important Pompeian block situated in the Regio IX, along Via di Nola. Results The aims of this research are two: to verify the presence of lipidic and proteinaceous material to spread the pigments, and to identify organic matter in painting materials owing to previous restoration works. The samples collected from the wall paintings of different rooms have been investigated by Fourier Transform Infrared Spectroscopy (FT-IR), and Gas Chromatography/ Mass Spectrometry (GC/MS). Conclusions The analytical results show that these Roman wall paintings were realized without the…
From Maya Blue to “Maya Yellow”: A Connection between Ancient Nanostructured Materials from the Voltammetry of Microparticles
2011
The yellow hue of a series of samples from wall paintings in several Mayan archaeological sites can be attributed to the presence of indigoid compounds, including isatin and dehydroindigo, attached to palygorskite, a local phyllosilicate clay. SEM/EDX, TEM, UV/Vis spectroscopy, and voltammetry of microparticles show that the ancient Mayas could prepare indigo, Maya Blue, and "Maya Yellow" during successive stages.

Minimal invasive Therapie bei peritonealer Leiomyomatose
1994
Leiomyomatosis peritonealis disseminata (LPD) is a rare benign disease characterised by the presence of multiple intraabdominal nodules, consisting of benign smooth muscle. LPD has only been found in women, predominantly in their late reproductive age. There is a very high association with excess exogenous and endogenous female gonadal steroids, specifically oestrogen and progesterone. Since it is grossly indistinguishable from diffuse carcinomatosis of the peritoneum, several unnecessary radical procedures have resulted. We describe the 44th documented case and the first case of minimal invasive surgery in a 42-year-old women with peritoneal leiomyoma on the right pelvic wall and uterine s…
Immunomodulation in vascularized composite allotransplantation: What is the role for adipose-derived stem cells?
2019
Hand and face transplants are becoming increasingly common, recording progressively more penile, uterus, abdominal wall, and allotransplantation cases reported worldwide. Despite current protocols allow long-term survival of the allografts, the ultimate goal of donor-specific tolerance has not been achieved yet. In fact, the harmful adverse effects related to the lifelong administration of immunosuppressive agents are the main drawbacks for vascularized composite allotransplantations. Research is very active in investigating alternative methods to induce greater tolerance while minimizing toxicity. Adipose-derived stem cells (ASCs) represent promising cell therapies for immunomodulation in …
Concrete thermal energy storage for linear Fresnel collectors: Exploiting the South Mediterranean’s solar potential for agri-food processes
2018
Abstract Italy is celebrated in the world for its agri-food industries while the process of production of pasta is highly energy demanding and requires both electrical and thermal energy simultaneously. Because most of the Italian factories producing pasta are located in the Southern part of the country, the direct use of thermal energy generated from the sun would be particularly profitable. In this study, the authors examine the possibility of generating by a Solar Industrial Process Heating plant the thermal energy required annually by an existing factory that produces durum wheat pasta located in Sicily (Italy). The hypothesized plant scheme consists of an array of Fresnel linear solar …
