Nonlinear optics from off-energy closed orbits

This paper describes a novel scheme for correcting the second order (chromatic sextupole) magnet lattice and its deployment on a fourth generation multibend achromat electron storage ring. The method is analogous to the well-established linear optics from closed orbits scheme, but uses an off-energy orbit response matrix to characterize the second order optics of a lattice. The matrix is construct

Modeling the Impact of a Model : The (Non)Relationship between China's Economic Rise and African Democracy

Many scholars have regarded China's emergence as an economic force as a threat to democracy in Africa, presenting China as the exporter of an authoritarian model through its rising economic influence. This article investigates how well founded the contended Chinese economic threat to Africa is by both analyzing the data at a very fundamental level and applying time-series, cross-sectional analysis

Quantifying archaeo-organic degradation – A multiproxy approach to understand the accelerated deterioration of the ancient organic cultural heritage at the Swedish Mesolithic site Ageröd

Despite a growing body of evidence concerning accelerated organic degradation at archaeological sites, there have been few follow-up investigations to examine the status of the remaining archaeological materials in the ground. To address the question of archaeo-organic preservation, we revisited the Swedish, Mesolithic key-site Ageröd and could show that the bone material had been subjected to an

Determination of biogenic amines by using amperometric biosensors based on grass PEA amine oxidase and OAT polyamine oxidase

Grass pea amine oxidase (GPAO) and oat polyamine oxidase (OPAO) were immobilized along with horseradish peroxidase (HRP) and an Os-redox polymer (Os-RP) onto the surface of a graphite electrode by crosslinking with poly(ethylenglycol) diglycidyl ether. The resulted reagentless amperometric biosensors were inserted in a flow injection setup and used as electrochemical detectors for the biogenic ami

Swedish national multicenter study on head and neck cancer of unknown primary : Prognostic factors and impact of treatment on survival

Introduction Head and neck cancer of unknown primary (HNCUP) is a rare condition whose prognostic factors that are significant for survival vary between studies. No randomized treatment study has been performed thus far, and the optimal treatment is not established. Objective The present study aimed to explore various prognostic factors and compare the two main treatments for HNCUP: neck dissectio

Socioeconomic development initiatives and women’s experiences of marital violence in rural Bangladesh

Socioeconomic development initiatives (SDIs) have become a controversial issue. In giving skill trainings and credit supports, practitioners assume that SDI participation will enhance women’s income/dignity. Some studies have indicated that SDIs reduce women’s exposure to marital violence (MV), while others have shown that they increase spousal conflicts/MV. Our study explains how SDI participatio

Regional inhaled deposited dose of indoor combustion-generated aerosols in jordanian urban homes

Indoor combustion processes associated with cooking, heating, and smoking are a major source of aerosols in Jordanian dwellings. To evaluate human exposure to combustion-generated aerosols in Jordanian indoor environments, regional inhaled deposited dose rates of indoor aerosols (10 nm to 25 µm) were determined for different scenarios for adult occupants. The inhaled deposited dose rate provides a

Risk of colorectal cancer in patients with diabetes mellitus : A Swedish nationwide cohort study

BACKGROUND: Colorectal cancer (CRC) incidence is increasing among young adults below screening age, despite the effectiveness of screening in older populations. Individuals with diabetes mellitus are at increased risk of early-onset CRC. We aimed to determine how many years earlier than the general population patients with diabetes with/without family history of CRC reach the threshold risk at whi

COVID-19 during Pregnancy and Postpartum:: I) Pathobiology of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) at Maternal-Fetal Interface

Coronavirus Disease 2019 (COVID-19) triggered by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection has been declared a pandemic by the World Health Organization (WHO) on March 11, 2020. Oxidative stress and its related metabolic syndromes are potential risk factors in the susceptibility to, and severity of COVID-19. In concert with the earliest reports of COVID-19, obstetricia

Prepare or resist? : Cold War Civil Defence and Imaginaries of Nuclear War in Britain and Denmark in the 1980s

The article explores how the global Cold War conflict was made sense of and situated in local political, cultural and physical landscapes and communities during the 1980s in Britain and Denmark. Using civil defence as a prism, the article employs a comparative approach to explore variations within and between countries of how local authorities prepared or resisted the prospect of nuclear war. The

The Health of Older Family Caregivers–A 6-Year Follow-up

It is unclear whether caregiving has an impact on the physical, mental and functional health of older caregivers. This study aimed to describe physical, mental and functional health in relation to family caregiving in old age (60+) over a six-year period. The study comprised 2,294 randomly selected individuals (60–96 years) from the Swedish National Study on Aging and Care, who answered the questi

Hydraulic Model Database for Applied Water Distribution Systems Research

At the 2013 World Environmental and Water Resources Congress in Cincinnati, Ohio, the ASCE Task Committee on Research Databases for Water Distribution Systems was formed to develop an online open-access repository of water distribution system hydraulic network files for use in applied scientific research. This paper discusses the development of the resulting database, specific model contributions,
