Is the definition of "permanent establishment", as used in the double tax agreements of selected 'oil rich' central and North African countries, sufficient to protect the taxing rights on the natural resources of these countries? [PDF]

open access: yes, 2011
Includes abstract.Includes bibliographical references (leaves 141-148).Given the considerable increase in international trade over the past 40 years, particularly between Africa and the rest of the world, there is a risk that the developing African ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Administrative Law Dilemma from Taxing the Economic Presence in Cloud Computing Post-Constitutional Court Decision in Indonesia

open access: yesAdministrative and Environmental Law Review
The expansion of the digital economy, particularly cloud computing, has exposed structural limitations in Indonesia’s Income Tax framework, which remains based on physical presence.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

open access: yesFEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Historical development of international criminal courts [PDF]

open access: yesRevija za kriminologiju i krivično pravo
This paper deals with the historical development of international criminal courts. The need for the establishment of an international criminal court has always been tied to armed conflicts and wars in which the most severe crimes had been committed - and

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Permanent Establishment – to Internet based establishment

open access: yes, 2009
It is more common now to purchase products and services on the Internet. More and more companies choose to sell their services and products this way. Some services and products the customers can get delivered directly to their computers. Therefore, it is
