This study examined an econometric analysis of the macroeconomic determinants of carbon dioxide (CO2) emission in Nigeria, covering the periods between 1981 and 2016, employing both linear and non-linear Autoregressive Distributed Lag (ARDL & NARDL) models. The time series data used were sourced from the database of the World Bank Development Indicators, 2016 and Central Bank of Nigeria Statis
Several scholars from various theoretical perspectives have proposed pieces of the peace puzzle. As scholars fit together the sometimes disparate pieces of this puzzle, the missing pieces become more visible, and gender is among them. While gender studies, feminist international relations (IR) scholars, and peace and conflict researchers informed by a gender perspective have contributed to this pu
A novel Stacked Multi-Level (SML) modulator topology optimized for long pulse and high average power applications has been developed at ESS. It utilizes six identical modules connected in series at the HV output side and fed in parallel from the low voltage side. Each one is formed by one HF inverter, one step-up transformer, one HV rectifier bridge and one HV passive filter. They are supplied, in
An insertion device lab was setup at MAX IV Laboratory and the production of insertion devices, mainly outof-vacuum is ongoing and aided by new magnetic measurement systems. A new 5.5 m long Hall probe bench is used for field map measurements and a new hybrid flip coil and stretch wire system will be used for field integrals of full devices as well as individual magnet blocks characterisation. Thi
The FACET-II facility, currently being designed at SLAC, will contain a small 20 m circumference, 335 MeV, positron damping ring. The ring has to fit in the existing linac tunnel, meaning that a compact lattice with short distances between magnets is required. The detailed magnet design is done in Opera-3d, with a finite element model of a full damping ring arc being simulated. This article presen
The tumor microenvironment can act so as to stimulate or reject tumor cells. Among the determining factors are cytokines produced, for example, by infiltrating immune cells, tumor cells, and fibroblasts. External radiotherapy has been shown to be able to activate an immune response against tumor cells with cytokine signaling as an important part of the activation. The aim of this study was to eval
This article analyses the application of the 1972 United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Convention (the WHC) in the context of the armed conflicts that have taken place in the Virunga National Park (the Park), a natural world heritage site in the Democratic Republic of the Congo (the DRC). Instead of addressing wartime environmental damage under t
The phenotype of human immunodeficiency virus type 1 (HIV-1) commonly evolves between and within infected individuals, at virus transmission, and during disease progression. This evolution includes altered interactions between the virus and its coreceptors, i.e., chemokine receptors, as well as mannose C-type lectin receptors (CLRs). Transmitted/founder viruses are predominantly restricted to CCR5
Organized human papillomavirus (HPV) vaccination was introduced in Sweden in 2012. On-demand vaccination was in effect from 2006 to 2011. We followed the HPV prevalences in Southern Sweden from 2008 to 2013.
The MAX IV facility includes two storage rings operated at 1.5 GeV and 3 GeV, which are both designed to operate with a uniform, multibunch fill pattern. Both rings have a 100 MHz RF system and employ passive harmonic cavities to damp instabilities and increase Touschek lifetime. Recently, a discussion on timing modes at the MAX IV storage rings has been initiated by the user community. Creating o
Objective - The release of fragments of cartilage oligomeric matrix protein (COMP) and aggrecan into knee joint fluid and serum after joint injury and in post-traumatic and primary osteoarthritis was monitored in a cross-sectional study. Methods - Samples of joint fluid and serum were obtained from healthy volunteers and from patients with arthroscopically verified injury to anterior cruciate liga
It is essential for the pulp and paper industry to utilize as much of the forest raw material as possible to achieve the sustainability goals and to increase the profit. The fibres that are liberated during the kraft pulping process are used for pulp production, while the rest of the components from the wood are mainly incinerated. Lignin is one major byproduct from the kraft pulping process. It h
Processes of rapid radiation among unicellular eukaryotes are much less studied than among multicellular organisms. We have investigated a lineage of cold-water microeukaryotes (protists) that appear to have diverged recently. This lineage stands in stark contrast to known examples of phylogenetically closely related protists, in which genetic difference is typically larger than morphological diff
Nighttime satellite photographs of Earth reveal the location of lighting and provide a unique view of the extent of human settlement. Nighttime lights have been shown to correlate with economic development and population but little research has been done on the link between nighttime lights and population change over time. We explore whether population decline is coupled with decline in lighted ar
Education reform in the Muslim Middle East is the crossroad of globalization, rapid economic development, socio-political changes and religious ideologies. The diverse pattern of the reforms is the reflection of the complexity across the region; affected by domestic factors and the nature and extent of the linkage to the global forces. Despite differences, reforms share four common interlinked fea
