The 494 km long Latvian coast consists of sandy sediments, which serve as an excellent proxy for past coastal events and environment. Our study explores these understudied sediments along the western coast of the Gulf of Riga and combines two sand quartz-wise methods: optically stimulated luminescence (OSL) dating and grain microtextures. We provide a new chronology and microsedimentary results to

Regeneration of Norway spruce, Picea abies, forests is to a large extent depending on the production of seeds from high quality plus trees in orchards. However, the seed yield is variable and unpredictable due to weather, pest insects and diseases. Thus, more knowledge is needed to improve planning of harvest and mitigation of pests and diseases to secure future forest regeneration. In this study,

This study investigates cross-border commercial air passenger traffic in Africa, focusing on the development of the 15 busiest country pairs during the period 1989 to 2015. It explores dimensions not previously studied by using ICAO’s ‘Traffic by Flight Stage’ (TFS) and data from the CEPII Gravity Dataset. The spatial results show on an uneven geographical distribution of country pairs with the ce

How does coalition participation influence party membership? We argue that parties that take part in coalition governments are likely to experience less favorable party membership developments than parties governing alone because of the compromises they have to agree on in multi-party cabinets. This should be particularly likely for parties in ideologically diverse coalition governments since part

BACKGROUND: The malaria parasite Plasmodium falciparum holds an extensive genetic polymorphism. In this pooled analysis, we investigate how the multiplicity in asymptomatic P. falciparum infections-that is, the number of coinfecting clones-affects the subsequent risk of clinical malaria in populations living under different levels of transmission.METHODS: A systematic search of the literature was

Objective: To assess the risk of suicide after a diagnosis of urinary bladder cancer (UBC) compared with the standard population and to identify potential risk factors and time dependence associated with suicide in patients with UBC. Method: We used data from the Bladder Cancer Data Base Sweden 2.0 (BladderBaSe), including all individuals aged 18 years or older, diagnosed with UBC between 1997 and

In this paper, I explore the practice of environmental management by international actors in institutionally weak states transitioning from peace to conflict (post-conflict) to analyse how these actors may fill an institutional and legal gap. This is of interest as it moves the governance of the environment in the post-conflict states from a domestic to an international level. In post-conflict sta

OBJECTIVES: To report the burden of cardiovascular diseases (CVD) in the Eastern Mediterranean Region (EMR) during 1990-2015.METHODS: We used the 2015 Global Burden of Disease study for estimates of mortality and disability-adjusted life years (DALYs) of different CVD in 22 countries of EMR.RESULTS: A total of 1.4 million CVD deaths (95% UI: 1.3-1.5) occurred in 2015 in the EMR, with the highest n

We investigate the steady-state performance of a single irreversible mixing-controlled reaction between segregated reactant streams entering the annular gap between coaxial cylinders that can rotate independently. The three-dimensional Stokes flow results from the superposition of a pressure-driven Poiseuille flow along the mixer axis, and a cross-sectional Couette flow generated by the steady rot

Fragment-based lead discovery (FBLD) has become a pillar in drug development. Typical applications of this method comprise at least two biophysical screens as prefilter and a follow-up crystallographic experiment on a subset of fragments. Clearly, structural information is pivotal in FBLD, but a key question is whether such a screening cascade strategy will retrieve the majority of fragment-bound

1. Opioid- and FMRFamide (FMRFa)-ergic systems are believed to play antagonistic behavioral roles in both higher and lower animals. In our previous experiments on a snail, behavioral choice has been demonstrated to be dependent on a balance between FMRFa and enkephalins [7]. Here, we examined if the disturbance of the balance causes changes in the activity of both systems. Opiate receptor blocker

A good heat transfer performance with moderate pressure drop penalty, as well as a high mixing effect contributes to the increase of a solar receiver thermal efficiency. In this study, delta-winglet vortex generators (DWVGs), and the combination of DWVGs and obstacles are numerically studied to reveal the effects on a solar receiver heat exchanger and the heat transfer, friction factor and mixing.

The role of genetic variability in dementia with Lewy bodies (DLB) is now indisputable; however, data regarding copy number variation (CNV) in this disease has been lacking. Here, we used whole-genome genotyping of 1454 DLB cases and 1525 controls to assess copy number variability. We used 2 algorithms to confidently detect CNVs, performed a case-control association analysis, screened for candidat

Start with a graph with a subset of vertices called {\it the border}. A particle released from the origin performs a random walk on the graph until it comes to the immediate neighbourhood of the border, at which point it joins this subset thus increasing the border by one point. Then a new particle is released from the origin and the process repeats until the origin becomes a part of the border it

BACKGROUND: Previous studies of non-smoking individuals with severe alpha-1-antitrypsin deficiency (PiZZ) have been sparse and included only a limited number of individuals, mostly identified by respiratory symptoms. The aim of this study was to estimate the prognosis of non-smoking PiZZ individuals and to analyze the most common causes of death by including a large number of individuals who had b
