More than 200 beads and pendants were found in seven trash middens excavated at the 4th/5th to the 6th century AD settlement site in Shenshef in the Eastern Desert of Egypt. The site lies close to the Sudanese border and the Red Sea coast, and about 20 km to the southwest of the ancient port of Berenike. Although the purpose of the settlement has not been established, excavations provided a wide range of imports from the Mediterranean region and the Indian Ocean. An overview of the materials and manufacturing techniques applied in the production of the beads and pendants confirms the short- and long-distance contacts of Shenshef inhabitants. In addition to the many bead parallels that link the site with the Red Sea ports and the Nile Valley region up to the First Cataract, the presence of South Indian/Sri Lankan beads at Shenshef is especially meaningful. They may be proof of the intermediary role played by the Shenshef inhabitants in trading overseas imports into the Nubian Nile Valley region.

Research background: The COVID-19 pandemic led to a change in consumer demand behavior worldwide. Due to the pandemic, individual sectors and industries experienced enormous demand or significant decreases in demand. Hardly any sector or industry remained unaffected by the influences and consequences of the COVID-19 pandemic. Due to the many worldwide restrictions of private travel, many German consumers stayed in their home country. German tourists are internationally regarded as world champions in travel, so the lack of private long-distance travel led to implications for other sectors. Another trend that has emerged in the wake of the COVID-19 pandemic is the so-called cocooning. Cocooning is the term used by trend researchers to describe a tendency for consumers to increasingly withdraw from civil society and the public sphere into their private lives at home. This combination of a lack of private travel and a retreat into private domestic life has led to enormous growth in the furniture, household goods, garden, and home improvement sectors. Purpose of the article: The pandemic-related shift in demand is examined using secondary market data. These are first systematically researched, reviewed, and analyzed. Then, by using growth figures, the German home and garden market is examined based on sales figures and pandemic-related changes are shown. Furthermore, the individual sales channels, the relevant market players, and market shares under the pandemic’s influence will be analyzed. Methods: Systematic analysis of market information and datasets in the home and gardening sector in Germany. Findings & Value added: Creation of an information base regarding the shift in demand of German consumers in the wake of the COVID-19 pandemic.

This paper presents an integrated spherical photoacoustic cell (SPAC) for trace methane (CH4) gas detection. Theoretical analysis and analogue simulations are carried out to analyze the acoustic field distribution of the SPAC at resonant and non-resonant modes. The finite element simulation results based on COMSOL show that the first-order radial resonant frequency and second-order angular resonant frequency are 24,540 Hz and 18,250 Hz, respectively, which show good agreements with the formula analysis results. The integrated SPAC, together with a high-speed spectrometer and a distributed feedback (DFB) laser source, makes up a photoacoustic (PA) spectroscopy (PAS) system, which is employed for CH4 detection. The minimum detection limit (MDL) is measured to be 126.9 parts per billion (ppb) at an average time of 1000 s. The proposed SPAC has an integrated, miniaturized and all-optical structure, which can be used for remote and long-distance trace gas detection.

In the autumn of 2019, the 2020 Padua Muscle Days (PMDs) were planned to be held from March 18 to March 21, 2020. The program listed Scientific Sessions to occur over three full days at either Padova University or the Hotel Augustus on Euganei Hills (Padova), Italy. Abruptly, however, in early January the Coronavirus COVID-19 outbreak started in China and changed the world perspectives. In Italy, the epidemia had the first Italian cases and victims in an area south of Milan and in a Village of the Euganei Hills (Vo Euganeo, Padova). Thus, it was a mandatory decision to post-pone the PMDs meeting to 19-21 November, 2020. Luckily, almost all chairs, speakers, and attendees accepted the decision and have assured their presence in late November by long-distance communications. Thus, the Collection of Abstracts were e-published in 30 (1) 2020 Issue of the European Journal of Translational Myology (EJTM) together with the many EJTM Communications submitted by speakers and attendees of the 2020 PMDs Here we add a few new entries and the detailed Program of the 2020 Virtual PMDs to be organized November 19-21, 2020 from the Hotel Petrarca of Euganei Hills (Padova), Italy. The Program of the 2020 Virtual PMDs ends with invitation by Zipora Yablonka-Reuveni and myself to the 2021 (Virtual) Padua Muscle Days, March 25-27, Euganei Hills (Padova), Italy.

Among the many insects under investigation as potential vectors of the oak wilt fungus in Wisconsin and elsewhere, the species of Pseudopityophthorus have attracted considerable attention. Although recent developments appear to indicate that the long-distance spread of this serious disease occurs primarily with the aid of other insects, our knowledge at present does not warrant the assumption that bark beetles play no part whatever. In the study of P. minutissimus from August, 1952, to the fall of 1953, considerable information concerning its biology in Wisconsin has been brought to light; and regardless of its relationship to the oak wilt problem it seems desirable at this time to make better known this member of the Wisconsin bark beetle fauna.
