The second part of the manuscript deals with stories of Rabbi Mordechai Benet (1753-1829) as told to the author by his grand-aunt.See also archival collection.Altmann was born in Nikolsburg (Maehren) in 1887 and died in 1963 in New York.

Fashion Culture: Fashion Metropolis Berlin
No full textBerlin was a fashion capital in the 1920s, with hundreds of thriving clothing manufacturers, most of them Jewish, before it was decimated by the Nazis. Author Uwe Westphal shares this history in a discussion with FIT historian Keren Ben-Horin and journalist Jennifer Altmann, whose grandfather ran one of Berlin’s fashion houses.Organized in partnership with the Museum at Eldridge Street
Economics in Persian-period biblical texts : their interactions with economic developments in the Persian period and earlier biblical traditions
No full textLarge-scale economic change such as the rise of coinage occurred during the Persian-dominated centuries (6th –4th centuries BCE) in the Eastern Mediterranean and ancient Near East. How do the biblical texts of the time respond to such developments?
In this study, Peter Altmann lays out foundational economic conceptions from the ancient Near East and earlier biblical traditions in order to show how Persian-period biblical texts build on these traditions to address the challenges of their day. Economic issues are central to the way that Ezra and Nehemiah approach the topics of temple building and of Judean self-understanding. Economic terminology and considerations also appear in Second Isaiah and the “Holiness Code.” Following significant interaction with the material culture and extra-biblical texts, the author devotes special attention to the ascendancy of economics and its theological and identity implications as structuring metaphors for divine action and human community in the Persian period.

Reinhard Köhler's Scientific Production: Words, Numbers and Pictures, di Arjuna Tuzzi
No full textThis study draws upon statistical analysis techniques of textual data to examine a corpus composed of 22 research articles published between 1997 and 2010 by Reinhard Köhler as a single author or in collaboration with other scholars. The aim of this article is to draw a representation of the main areas of interest of his research. After having drawn an overall representation of the corpus, Köhler’s latest work – an unpublished volume on Quantitative Syntax Analysis – was analysed to understand its role within the context of his research
Assessment of Microplastic and Contaminant Emissions from Artificial Turf Sports Pitches
No full textDue to their advantages over natural gras, artificial turf sports pitches are well established in popular sports and their number is increasing every year. This raises questions about potential pollutant emissions and possible risks to the environment due to its transfer to soil and groundwater.
The main sources of emissions are the rubber infill granules and the abrasion of grass fibers. While estimates on the transfer of pollutants to the soil are already available, there is still insufficient data on the discharge of microplastics from artificial turf systems and thus on the assessment of its relevance for the soil.
To close this gap, the pollutant emissions of three artificial turf scenarios - past (fossil-based, rubber infill), present (most frequently installed in Germany, rubber infill) and future (turf with recycled grass fibers, no rubber infill) - were compared in different ageing states (unaged, accelerated, and real time aged). Accelerated ageing consisting of UV weathering and mechanical stress was applied to simulate the outdoor weathering of turf systems during their service life span of approx. 15 years. Emissions of microplastics and environmentally relevant pollutants were sampled simultaneously using newly developed, innovative lysimeters. The microplastics contents were determined using Thermal Extraction-Desorption Gas Chromatography/Mass Spectrometry (TED-GC/MS). In addition, the concentrations of PAH and heavy metals were determined

Development of a new Lysimeter System to assess Microplastic, PAH & Heavy Metal Emissions from Artificial Turf Sports Pitches
No full textSince September 2023, the European Commission introduced a new regulation to reduce emissions of microplastics (MP) into the environment, including the sale and use of intentionally added MP. Therein, the use of synthetic rubber granules in artificial turf is explicitly mentioned and banned for future use. Additionally, abrasions of grass fibres and other turf components are also considered as MP sources. Artificial turf pitches are multi component systems: e. g. grass fibres made of polyethylene (PE), synthetic infill made of ethylene propylene diene monomer rubber (EPDM), carpet backing of polypropylene (PP) glued with polyurethane (PU), winding yarn of polyethylene terephthalate or elastic layer of Styrene-butadiene rubber (SBR) bound with PU. While the ban has great impact on recreational sports, there is so far no sufficient data to estimate the MP emissions from artificial turf sports pitches into the environment and thus their relevance as a source of MP pollution.
To close this gap, three artificial turf scenarios in different ageing states (unaged, artificially aged and aged in real time) were analysed in this study: the past (old turf: fossil based, synthetic infill), present (most commonly installed in Germany: fossil based, synthetic infill) and future (turf with recycled grass fibres, no synthetic infill). To simulate outdoor weathering during the service life of approx. 15 years, accelerated ageing by UV weathering and mechanical stress was carried out. The newly developed and in-house manufactured Microplastic Eluate Lysimeter (MEL) simulates contaminant transfer into the groundwater and allows the simultaneous sampling for MP and dissolved contaminants, like polycyclic aromatic hydrocarbons (PAH) or heavy metals (HM). MP mass contents were analysed using smart microfilter crucibles (mesh size: 5 µm) and Thermal Extraction Desorption Gas Chromatography/Mass Spectrometry and PAH and HM concentrations were determined using Gas Chromatography/Mass Spectrometry or Inductively Coupled Plasma Atomic Emission Spectroscopy, respectively
Contaminant Emissions from Artificial Turf Sports Pitches - Simultaneous sampling for Microplastics, PAH and Heavy Metals
No full textIn September 2023, the European Commission introduced a new regulation to
reduce microplastic (MP) emissions into the environment, including the sale and
use of intentionally added (large) MP < 5 mm (ISO/TR 21960: 2020). This explicitly
applies to the use of synthetic rubber granulate infill in artificial turf installations,
which are complex multi-component systems consisting of multiple synthetic
polymers (Fig. 1). In addition, abrasions of synthetic grass fibres and other turf
components are also considered as MP sources. Although this has a major impact
on public recreational sports, there is so far no sufficient data to estimate the MP
emissions from artificial turf sports pitches into the environment and thus their
relevance as a source of MP pollution.
To close this gap, this study compared environmental contaminant emissions of
three artificial turf scenarios at different ageing states (unaged, artificially and
real-time aged): the past (old turf: fossil based, synthetic infill), present (most
commonly installed in Germany: fossil based, EPDM infill) and future (turf with
recycled grass fibres, no synthetic infill). Accelerated ageing by UV weathering and
mechanical stress was carried out to simulate the outdoor weathering during the
lifespan of approx. 15 years. MP emissions and released environmentally relevant
contaminants posing a risk to the groundwater were simultaneously sampled using
the newly developed Microplastic Eluate Lysimeter manufactured at BAM (Fig. 2).
MP contents were analysed using smart microfilter crucibles (mesh size: 5 μm)
with subsequent MP detection by TED-GC/MS. Additionally, concentrations of
polycyclic aromatic hydrocarbons were determined using GC/MS and heavy metals
using ICP-AES
