Abstract Charles Goodyear is best known for a single patent, U.S. patent 3633, “Improvements in India Rubber Fabrics Vulcanization of Rubber” (1849). The story of Goodyear and his 1839 discovery of vulcanization, a method to increase the strength and resiliency of rubber, has been told in several well-researched accounts. What has not been accomplished is a compilation of the complete patents of Goodyear. Although many books and articles discuss the patents of Charles Goodyear, up to this point there was no single comprehensive and accurate list of his patents including all the information needed to retrieve the original documents from the issuing patent organizations. Librarians of the Rubber Division, American Chemical Society and the University of Akron, using both print and online resources, were able to compile a complete list of Goodyear's patents issued in the 19th Century.

Abstracttitle SUMMARY /title We present here the letters of the "Fondo Siacci" which was found recently while reorganising some papers from the old seat of the library at the Department of Mathematics "Renato Caccioppoli" of the University "Federico II" of Naples, in Via Mezzocannone 8. Grancing at these letters we discovered their interest to reconstruct various historical events of italian mathematics life in the 2nd half of the 19th century.

Institute of the Lithuanian Language At the beginning of the 19th century, the financial possibility to establish a department of Eastern languages at one of the oldest universities in Eastern Europe, Vilnius University, appeared. Turkish was among the Eastern languages that were expected to be taught. The intensive preparation of lecturers was started. Unfortunately, the ambitious plans were destined to never become reality; in 1832 the university was closed. Nevertheless, over the following two centuries the Turkic direction did not disappear; in one form or another it surfaced and retained its vitality. There was a sympathetic environment: Tartars and Karaims—both Turkic ethnic groups—began settling in the Grand Duchy of Lithuania in the 14th century. Vilnius University was the cradle of many famous Orientalists who maintained Turkic research by their activities. In such a way, two main research subjects appeared: Kitabistik and the Karaim language. In this article, the origin problems, development and prospects of Turkic research will be examined.

The first recorded visit to Grímsvötn occurred on the 31st of August 1919. Two Swedish geology students, Hakon Wadell and Erik Ygberg, stood on the edge of a hitherto unknown large caldera. This discovery was the most significant finding in the first west-to-east transect across Vatnajökull, starting at Síðujökull on the 27th of August. This was an expedition into the unknown, but a principal aim was nevertheless to find the source of the large jökulhlaups on Skeiðarársandur. They named the ice-filled caldera “Svíagígur”. Studies of written sources in the 1930s revealed that this place was indeed Grímsvötn, well known in the 17th and 18th centuries but the name and location had been forgotten in the 19th century. From Svíagígur they continued eastwards, descending down the crevassed Heinabergsjökull, reaching civilization in the morning the 6th. They announced the news that a huge volcano existed under Vatnajökull and this was the source of the jökulhlaups emerging from Skeiðarárjökull. Upon their return to Stockholm, they received a hero’s welcome, but soon it all changed into no one believing them, as prominent figures in Sweden at this time insisted that a volcano can’t be active beneath a glacier! After they finished their studies, both left Sweden very disappointed. Hakon Wadell had a successful geological career in America presenting a doctoral thesis in 1932 from the University of Chicago. Erik Ygberg worked as an international prospector a few years before his bad health, a result of the hardships experienced at the end of the Vatnajökull expedition, forced him back to Sweden, where he had a career at the Swedish Geological Survey. The name Svíagígur has not been used but the two nunataks marking the highest points on Grímsfjall are named in the honour of the two Swedes, Svíahúkur eystri and Svíahnúkur vestri.

In the following paper, we look at the Alhambra from a perspective of architectural ceramics, an essential element in the understanding of the monument. From the Nasrid era onward, glazed ceramic tile mosaics were used to adorn the walls, a style that extended into the Christian conquest, when the palace complex was used as a royal residence. Since then, restoration work has continued to be carried out on the alicatados that cover the Alhambra’s walls, especially during an intense period in the 19th century, when it was the subject of much interest from Romantic travellers to Granada. A detailed, documented analysis of this work shows the complexity of the palace and fortress complex, helping us to better understand a part of its history. In the following pages, we specifically focus on one room in the Alhambra, the so-called Cuarto Dorado (Golden Room), outlining the preliminary findings of a research project that we are undertaking in association with the University of Granada and the Patronato de la Alhambra y el Generalife (Council of the Alhambra and the Generalife).
