Purpose: The vast majority of previous studies suggest that there is no relationship between the acceptable noise level (ANL) and pure-tone hearing thresholds reported as the average pure-tone hearing thresholds (pure-tone average). This study aims to explore (a) the relationship between hearing thresholds at individual frequencies and the ANL and (b) a measure of the slope of the audiogram and AN
People in Small Island Developing States are particularly vulnerable to displacement by disaster. Governments in the Caribbean and the Pacific need urgently to do more risk management and planning, rather than focusing almost exclusively on response and relocation.
BACKGROUND: Oxaliplatin and Mitomycin C (MMC) are both suitable as intraperitoneal chemotherapy agents in HIPEC for peritoneal carcinomatosis (PC) of colorectal cancer (CRC).METHODS: Patient cohorts from two different HIPEC-centers underwent cytoreductive surgery and HIPEC with Oxaliplatin (39 patients) and MMC (56 patients), respectively. They were compared for toxicity and survival data. The ext
BACKGROUND: Firefighting foam-contaminated ground water, which contains high levels of perfluoroalkyl substances (PFAS), is frequently found around airports. In 2018 it was detected that employees at a municipal airport in northern Sweden had been exposed to high levels of short-chain PFAS along with legacy PFAS (i.e., PFOA, PFHxS, and PFOS) through drinking water.OBJECTIVES: In this study, we aim
This article addresses the temporality of resistance in the work context. We focus on the challenge of increasingly diminishing professional autonomy in higher education institutions as well as the vulnerability of staff subjected to academic managerialism. A case where a lecturer is exposed to the requirements to revise grading by senior administration is investigated. Power is understood from th
Purpose:To correlate the parenchymal texture features at digital breast tomosynthesis(DBT)and digital mammography with breast percent density(PD), an established breast cancer risk factor, in a screening population of women. Materials and Methods: This HIPAA-compliant study was approved by the institutional review board. Bilateral DBT images and digital mammograms from 71 women (mean age, 54 years
We document that a high level of natural productivity of the ocean - a rich bounty of the sea - has had a positive and persistent impact on economic development since pre-industrial times until today. In addition, we document that it is the bounty of the sea of the ancestors of current populations which drives the persistent effect, not geography per se. We argue that an explanation is that a rich
In the hamiltonian formulation of fermions coupled to external gauge fields, the axial anomaly has a simple physical interpretation in terms of level shifting at the top of the Dirac sea. We apply this formalism to lattice QED in 1 + 1 and 3 + 1 dimensions, in order to study how the lattice regulation and small fermion mass affect the picture. For a simple choice of the E and B fields, it is possi
Background: Pancreatic cancer has been and still is associated with a very poor prognosis. This is due to a lack of major breakthroughs with respect to early diagnosis, prognostication, prediction, as well as novel, targeted therapies. The benefits of surgery and chemotherapy are evident, but the fact that only some 10% of all patients have early, localized disease highlights the unmet need for ne
Background and purpose — Obesity has been associated with inferior outcomes after laminectomy due to central lumbar spinal stenosis (CLSS); we evaluated whether this occurs in surgery on national bases. Patients and methods — We retrieved pre-and 1-year postoperative data from the National Swedish Quality Registry for Spine Surgery regarding patients aged ≥ 50 with laminectomy due to CLSS in 2005–
A brief pedagogical introduction to correlation femtoscopy is given. We then focus on the shape of the correlation function and discuss the possible reasons for its departure from the Gaussian form and better reproduction with a Lévy stable distribution. With the help of Monte Carlo simulations based on asymmetric extension of the Blast-Wave model with resonances we demonstrate possible influence
The water use associated with electricity generation and consumption has been the focus of research for decades. This study provides an overview of the water–electricity nexus from the perspectives of electricity production and consumption. In terms of production, the electricity generation and associated water use for various regions are summarized and compared. The spatial mismatch between water
In various environments new agents may base their decisions on observations of actions taken by a few other agents in the past. In this paper we analyze a broad class of such social learning processes, and study under what circumstances the initial behavior of the population has a lasting effect. Our results show that this question strongly depends on the expected number of actions observed by new
This study sought to assess the safety and efficacy of transcatheter valve annuloplasty in patients with mitral regurgitation (MR).
