Craft Specialization in Administration in Pre- and Protodynastic Egypt

open access: yesMiṣriqiyā, 2021
Administration in Egypt is one of the key areas of research, which reflects on the organization of the government and the complexity of The Centralized Economy as well as of Society. Its evidence almost entirely dependes on textual evidence that contains

Roman lead sealings [PDF]

open access: yes, 1995
This thesis is based on a catalogue of c.1800 records, covering over 2000 examples of Roman lead sealings, many previously unpublished. The catalogue is provided with indices of inscriptions and of anepigraphic designs, and subsidiary indices of ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Regional Epidemiological Study on the Dental Status of the First Permanent Molar in Romanian Schoolchildren

open access: yesDentistry Journal
Background/Objectives: Dental caries remains a significant public health challenge in Romania, with recent studies reporting a prevalence of 40% in children’s permanent teeth, with 90% of cases untreated. This study aimed to evaluate the dental status of

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Polymer-modified bentonite-silt composites to improve the hydro-mechanical properties of landfill mineral sealings [PDF]

open access: yesE3S Web of Conferences
Compacted clay layers are widely used in landfill barrier systems, relying on low-permeability soils to prevent leachate migration. When local soils like silts lack sufficient sealing properties, bentonite is added to enhance impermeability due to its ...

Umayyad Lead Sealings [PDF]

open access: yes, 2010
The following article will deal with Islamic sealings from Umayyad jund al- Urdunn and jund Filasṭīn. A few things have to be said as we start. The Umayyad period stretches from 41-132 H/661-750 C.E.
