Commercial enterprises who want to make use of the expertise and facilities are referred to LAB , the commercial unit responsible for specialized laboratory work.

Our staff has a strong international reputation and a broad research network, facilitating international student exchange. They lead projects world-wide, from France to the Caribbean, and from Ethiopia to Russia.

Prof.dr. Annelou van Gijn has obtained a Marie Curie subsidy for research on wetland activity patterns in Mesolithic Northwest Europe. This funding has been used to employ the researcher dr. Aimée Little. The project will commence in November 2011.

Tracing the residues of Neolithic activities through the study of stone artefacts

The unit residue group, to which the present thesis is devoted, is defined using the norm-residue symbol, which Hilbert introduced into algebraic number theory in 1897.

An algorithm is discussed to compute the exponential representation of principal units in a finite extension field F of the p-adic rationals.

What are the key issues in conducting LCA of bioenergy systems? What is the environmental sustainability status of second generation bioethanol? How much would the final results of biogenic carbon neutrality assumptions deviate from the true values based on a complete inventory? How to assess the impact…

Investigating Neolithic houses in Britain through microwear and residue analysis of stone tools

Evolution acts via mutations in amino acid sequences. Substitution of essential amino acids leads to a nonfunctional protein. l.

The Laboratory of Material Culture Studies welcomes two new researchers in October 2013. Dr. Christina Tsoraki and Dr. Benjamin Tun-Yee Chan, both from the Department of Archaeology of the University of Sheffield, received a Marie Curie research fellowship and will perform their research for 24 months…

The ability to create objects and structures with our hands has been essential to human development. This ability is something modern society is at risk of losing. Leiden archaeologists gather knowledge about ancient processes of ‘making and creating’ over the centuries, knowledge that helps our current…

The production, use, and exchange of bodily ornaments through the lenses of the microscope

The routine assumption that Upper Palaeolithic early modern humans in Europe were regular fire users who produced fire at will has never been tested against the archaeological record. Utilizing literature, database and microwear analytical approaches, this project seeks to establish the role and forms…

Tracking early human behaviour through plant processing and -exploitation.

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

Basketry, cordage and textiles made of plant fibers or bark are rarely preserved in the archaeological record. By means of experimental archaeology and microwear analysis, we obtain indirect evidence about this important craft.

When do fire making tools appear in prehistory, and how might the use of these tools manifest in the archaeological record?

Ongoing microwear analysis of the flint artefacts from the Funnelbeaker period suggests that flint had a pivotal role in the representation and structuration of the cosmological order of Funnelbeaker society.

... which focuses on the development and use of new multivariate statistical tools needed for analyses of data collected in the four other programs.

The Explainatory Data Analysis group develops algorithms and theory that enable domain experts to explain data by finding interpretable patterns and models.

Obtaining imaging data is nowadays only the start of your project. Once the data has been acquired there are many things that still need to be done.

The research of our group is centered around dynamical systems, functional analysis and their interplay.

The research of this programme is centered around dynamical systems, functional analysis, and their interplay.

The Institute of Environmental Sciences has carried out and participates in several projects that deal with the analysis of energy systems.

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

In this publication, Prof. Tahir Abbas, Inés Bolaños Somoano, Joana Cook, Isabelle Frens, Graig R. Klein and Richard McNeil-Willson look into the manifesto that was linked to the Buffalo attack in order to better understand the broader context and specific factors that motivated the perpetrator.

The main methodological aspects of the use of stepwise LCA estimators under different circumstances.

This handbook provides a resource for those already familiar with some kinds of micro-particles who wish to learn more about others, or for those just starting out in the study of microremains who wish to have a broad understanding about microscopic archaeology.

The objective is to develop in vitro antigen degradation assays in order to mimic the fate of the antigen in vivo.

Lecture, LUCIS What's New?! Series

The volume is one-stop shopping for crisis studies and a number of closely related fields, providing a window onto the latest thinking in the field. The articles reflect cutting edge, state of the art scholarship and pose key questions for research and practical development.

The focus of the Multicriteria Optimization and Decision Analysis (MODA) group is to develop foundations of methods in multi-objective optimization.

What are the capabilities or limitations of traveling between islands and how does this reflect seasonal variation? Is it possible to show higher levels of connectivity between islands based on generated pathways between several sites on two separate islands?

We live in a world of things and people in the past must have been as closely entangled with their material surroundings as we are now. In the Laboratory for Artefact Studies Van Gijn takes a close look at the biographies of objects: what kind of raw material an object is made off and what is its provenience,…

This thesis is based on five papers on several topics.
