International and Local Visions of the Justice and Security Sector in the West Bank

Considerable efforts by leading experts and funds from around the world are put into restructuring the West Bank justice and security sector (JSS). This is an effort done in a highly contested environment, with an ongoing Israeli occupation and weak local trust in the Palestine Authority (PA). This article analyzes the understandings by local Palestinian non-government organizations and internatio

Simulations of the Titration of Linear Polyelectrolytes with Explicit Simple Ions: Comparisons with Screened Coulomb Models and Experiments

Monte Carlo simulations of linear, weak polyacids and explicit simple ions have been performed in a spherical cell model to study the shift in the apparent dissociation constant. The simulations are performed in a canonical ensemble with the apparent dissociation constant calculated in a procedure based on Widom’s particle-insertion method. The effects of model parameters are discussed, for exampl

Search for sleptons in e+e- collisions at √s = 183 to 189 GeV

Data taken by the DELPHI experiment at centre-of-mass energies of 183 GeV and 189 GeV with a total integrated luminosity of 212 pb-1 have been used to search for the supersymmetric partners of the electrons, muons, and taus in the context of the Minimal Supersymmetric Standard Model (MSSM). The decay topologies searched for were the direct decay (ℓ̃ → ℓx̃), producing acoplanar lepton pairs plus mi

Prediction of diabetes with body mass index, oral glucose tolerance test and islet cell autoantibodies in a regional population

Objective. Our aim was to test the hypothesis that a combination of markers for Type 1 diabetes (glutamate decarboxylase and IA-2 autoantibodies) and for Type 2 diabetes [oral glucose tolerance test (OGTT) and body mass index (BMI)], would predict clinical diabetes in a regional population. Design. A population-based follow-up cohort study. Setting. Participants visited the primary health care cen

Proportional–Integral Controller Design for Combustion-Timing Feedback, from n-Heptane to iso-Octane in Compression-Ignition Engines

The problem of designing robust and noise-insensitive PI controllers for pressure-sensor based combustion-timing control was studied through simulation. Different primary reference fuels (PRF) and operating conditions were studied. The simulations were done using a physics-based, control-oriented model with an empirical ignition-delay correlation. It was found that the controllable region, in-betwThe problem of designing robust and noise-insensitive PI controllers for pressure-sensor based combustion-timing control was studied through simulation.

A temporally explicit species distribution model for a long distance avian migrant, the common cuckoo

Modelling the distribution of migratory species has rarely been extended beyond breeding and wintering ranges despite many species showing much more complex movement patterns with multiple stopovers. We aimed to create a temporally explicit species distribution model describing the full annual distribution cycle, and use it to model the complex seasonal shifts in distribution of the common cuckoo

Habitat diversity and ecosystem multifunctionality : The importance of direct and indirect effects

Ecosystems worldwide are facing habitat homogenization due to human activities. Although it is commonly proposed that such habitat homogenization can have negative repercussions for ecosystem functioning, this question has yet to receive explicit scientific attention. We expand on the framework for evaluating the functional consequences of biodiversity loss by scaling up from the level of species

Late magmatic controls on the origin of schorlitic and foititic tourmalines from late-Variscan peraluminous granites of the Arbus pluton (SW Sardinia, Italy) : Crystal-chemical study and petrological constraints

Tourmalines from the late-Variscan Arbus pluton (SW Sardinia) and its metamorphic aureole were structurally and chemically characterized by single-crystal X-ray diffraction, electron and nuclear microprobe analysis, Mössbauer, infrared and optical absorption spectroscopy, to elucidate their origin and relationships with the magmatic evolution during the pluton cooling stages. The Arbus pluton repr

Technology and Scale Changes : The Steel Industry of a Planned Economy in a Comparative Perspective

This paper provides an analysis of the role of technical advances and upscaling practices in the steel sector and the differences in these practices between planned and market-based economies. It focuses on the Czechoslovak steel sector, comparing it to other planned economies as well as Western economies. The primary method of analysis employed is the logistic-fit curve of technology diffusion, c

Dendritic cell migration to skin-draining lymph nodes is controlled by dermatan sulfate and determines adaptive immunity magnitude

For full activation of naïve adaptive lymphocytes in skin-draining lymph nodes (LNs), presentation of peptide:MHC complexes by LN-resident and skin-derived dendritic cells (DCs) that encountered antigens (Ags) is an absolute prerequisite. To get to the nearest draining LN upon intradermal immunization, DCs need to migrate from the infection site to the afferent lymphatics, which can only be reache

Effects of the nitrone radical scavengers PBN and S-PBN on in vivo trapping of reactive oxygen species after traumatic brain injury in rats

In previous studies, the authors showed that the nitrone radical scavenger alpha-phenyl-N- tert -butyl nitrone (PBN) and its sulfo-derivative, 2-sulfo-phenyl-N- tert -butyl nitrone (S-PBN), attenuated cognitive disturbance and reduced tissue damage after traumatic brain injury (TBI) in rats. In the current study, the production of reactive oxygen species (ROS) after TBI was monitored with microdia

Ecological innovations in the Cambrian and the origins of the crown group phyla

Simulation studies of the early origins of the modern phyla in the fossil record, and the rapid diversification that led to them, show that these are inevitable outcomes of rapid and long-lasting radiations. Recent advances in Cambrian stratigraphy have revealed a more precise picture of the early bilaterian radiation taking place during the earliest Terreneuvian Series, although several ambiguiti

Acceptance tests and quality control (QC) procedures for the clinical implementation of intensity modulated radiotherapy (IMRT) using inverse planning and the sliding window technique : experience from five radiotherapy departments

BACKGROUND AND PURPOSE: An increasing number of radiotherapy centres is now aiming for clinical implementation of intensity modulated radiotherapy (IMRT), but--in contrast to conventional treatment--no national or international guidelines for commissioning of the treatment planning system (TPS) and acceptance tests of treatment equipment have yet been developed. This paper bundles the experience o

Alejo Carpentier (1904-1980) is one of the most distinguished writers in Latin American literature and numerous studies have delved into his literary works. However, very little is known about his private life and family background apart from the facts that he chose to reveal about himself. Indeed, several of these “facts” have turned out to be false. This thesis sets out to examine whether a hidd

Is Migration Threatening Social Trust in Europe?

Bergh considers the relationship between migration and interpersonal trust in the European Union. Interpersonal trust, Bergh avers, is an important foundation for a well-functioning society. The question is how interpersonal trust is affected by increased migration in countries with differing levels of trust. Bergh shows that migrants from low-trust countries who move to high-trust ones show highe
