An Ancient Egyptian System of Workmen’s Identity Marks

On 7 November 2018, Catherine Harwood defended her thesis 'Navigating Between Principle and Pragmatism: The Roles and Functions of Atrocity-Related United Nations Commissions of Inquiry in the International Legal Order'. The doctoral research was supervised by Prof. dr. L.J. Van den Herik and Prof.…

This dissertation is a study of archaeological remains left behind by nomadic communities in the Black Desert, situated in the northeast of modern Jordan.

This thesis aimed to investigate core cross-linked polymeric micelles (CCPMs) and expand their potential for the delivery of hydrophobic drugs and co-factors.

The rationale, construction, and function of the imperial capitals of Assyria

Archaeologists and students from Leiden University and local volunteers have found a Roman camp in the woods near Ermelo. The camp is four kilometres away from another Roman fortification discovered some time ago. This confirms the idea that the Romans would also often explore beyond the boundaries…

The Assyrian Empire was the first state to achieve durable domination of the Ancient Near East, enduring some seven centuries and, eventually, controlling most of the region. Yet, we know little about how this empire emerged from a relatively minor polity in the Tigris region and how it managed to consolidate…

Innovating objects in a Eurasian center of the Late Hellenistic period.

On the 15th of July Sawako Takemura successfully defended a doctoral thesis and graduated.

For the first time, a group of international and interdisciplinary researchers led by Karline Janmaat and her former MSc Student Chirag Chittar, have tested the several hypotheses on music simultaneously in a modern foraging society during their daily search for tubers – their staple food. They found…

In this thesis, I study 1) metabolic alterations in tuberculosis related to wasting syndrome in human patients as well as in rodent and fish animal models. 2) effects of the mutation of the leptin gene on cachexia and diabetes in rodent and zebrafish animal models.

Form and Function in Greek Grammar. Linguistic Contributions to the Study of Greek Literature is a new book, written by Albert Rijksbaron. Rijksbaron is internationally known as one of the leading scholars of the Ancient Greek language, whose work has exerted a strong and lasting influence on the scholarly…

What are the precise identities, possibilities and current practice examples of the various time frames in music and what bearings do they have individually and in combinations on the speed of the music?

Psychologist Bernadet Klaassens initiated a large fMRI study on the effect of drugs on brain networks in aging and Alzheimer's disease. It generated a unique data set and insight into a new method to develop drugs for patients with Alzheimer's.

The outermost layer of the skin, the stratum corneum (SC), is responsible for the skin barrier function, protecting the body from pathogens, chemicals and other unwanted substances from the external environment. The SC lipid matrix provides the only continuous pathway through the SC and is considered…

To argue that people can control the relative contributions of goal-driven and stimulus-driven processes to decision-making and action selection.

This study is the first to directly relate brain development to sex differences and school performance. The results debunk the myth that brain development is slower in boys.

The aim of this thesis was to study the link between hearing loss, language skills, and social functioning in deaf and hard of hearing (DHH) children. Sufficient language skills are an essential prerequisite to develop appropriate communication skills, in order to join in conversations with others.…

To what end and how does Plautus constantly underline the Helleni(sti)c provenance of his art? How does this aspect relate the author’s originality?

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

On the 20th of June, Camil Staps successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Camil on this achievement!

This thesis focused on the exploration of monolayer graphene as a membrane in direct methanol fuel cell (DMFC) applications, with improvements achieved through plasma exposure or damage- free chemical functionalization.

PhD defence

Quasicrystals are crystals with ‘impossible’ five-fold symmetries, which nevertheless were synthesized in the lab in 1982. Paul J. Steinhardt helped figure out their structure, but he didn’t stop at that.

Ice, the solid state of water, plays an important role on our planet as well as the entire universe.Despite the fact that an individual water molecule has a very simple structure, its chemical bonding in the solid phase can be surprisingly complex.

Fatemeh (Simin) Tabassi Mofrad has recently received a project grant (€ 25,000) from LUF/Gratama Foundation for her ideas in investigating sex-by-genotype interactions in brain functions. She has a multidisciplinary research perspective which enables her to look at research issues from different angles.…

Are disturbances to the brain, such as Alzheimer's or autism, linked to specific defects in the underlying communication networks in the brain? If this is the case, subtle changes in the networks can act as a marker for brain disturbances. Neuroscientist Serge Rombouts will be investigating this, together…

The lipid matrix of the skin's stratum corneum plays a key role in the barrier function, which protects the body from desiccation. The lipids that make up this matrix consist of ceramides, cholesterol, and free fatty acids, and can form two coexisting crystalline lamellar phases: the long periodicity…

Based on the results of a language-switching experiment, PhD candidate Fatemeh (Simeen) Tabassi Mofrad MA and Professor Niels Schiller have discovered that the traditional categorisation of brain areas is not sufficient. They published their research findings in the scientific journal NeuroImage.

Three Leiden astronomers have shown that some asteroids that are considered harmless for now, can collide with Earth in the future. They did their research with the help of an artificial neural network. The results have been accepted for publication in the journal Astronomy & Astrophysics.

Throughout history, a large portion of the world's population has lived under imperial rule. Although scholars do not always agree on when and where the roots of imperialism lie, most would agree that imperial configurations have affected human history so profoundly that the legacy of ancient empires…

The Archaeology of Imperial Landscapes examines the transformation of rural landscapes and societies that formed the backbone of ancient empires in the Near East and Mediterranean. Through a comparative approach to archaeological data, it analyses the patterns of transformation in widely differing imperial…
