Paternal shift-working and sleep disorders in children affected by primary nocturnal enuresis

2017

Objectives: Primary monosymptomatic nocturnal enuresis (PMNE) is a common problem in childhood and studies about the sleep habits of affected children are not conclusive. Work-family conflict (WFC) results from the incompatibility between family demands and business/workplace needs. WFC can impact parental quality with many consequences on children health. Aim of study is assessing the prevalence of sleep disturbances in enuretic children, sons of work-shifters. Materials and methods: 80 children (67 males) aged 5-13 years (mean 10,43; SD ± 1,99), were consecutively referred for PMNE. Sleep habits were investigated with Sleep Disturbances Scale for Children (SDSC) and the results were compa…

Objective Diabetic retinopathy (DR) is the leading cause of blindness in people of working age. The purpose of this paper is to report the prevalence and cardiovascular associations of diabetic retinopathy and maculopathy (DMac) in Germany.

Short-term Neuropsychiatric Outcomes and Quality of Life in COVID-19 Survivors

2020

ABSTRACTBackgroundThe general medical impacts of coronavirus (COVID-19) are increasingly appreciated. However, its impact on neurocognitive, psychiatric health and quality of life (QoL) in survivors after the acute phase is poorly understood. We aimed to evaluate neurocognitive function, psychiatric symptoms, and QoL in COVID-19 survivors shortly after hospital discharge.MethodsThis was a cross-sectional analysis of a prospective study of hospitalized COVID-19 survivors followed-up for 2 months after discharge. A battery of standardized instruments evaluating neurocognitive function, psychiatric morbidity, and QoL (mental and physical components) was administered by telephone.FindingsOf the…

Pulmonale Hypertonie bei Linksherzerkrankungen

2010

The 2009 European Guidelines on Diagnosis and Treatment of Pulmonary Hypertension have been adopted for Germany. While the guidelines contain detailed recommendations regarding pulmonary arterial hypertension (PAH), they contain only a relatively short paragraph on other, much more frequent forms of PH such as PH due to left heart disease. Despite the lack of data, targeted PAH treatments are increasingly being used for PH associated with left heart disease. This development is of concern. On the other hand, PH is a frequent problem that is highly relevant for morbidity and mortality in patients with left heart disease, so that it may be speculated whether selected patients may benefit from…

An Empirical Study of Performance Appraisal and Career Opportunities

2011

Using survey data from a large international oil company, this econometric study explores the perceptions ofperformance appraisal and career opportunities on one hand, and how this is dependent on variation in propertiesand characteristics of the local working environment on the other hand. Perceptions indicate that performanceand payoff are better balanced among women than among men. Moreover, the connection between perceivedachievement and appreciation is strengthened by time of service for leaders, but not for employees innon-managerial positions. Finally, perceptions of performance appraisal and career opportunities depend oncharacteristics of the local work environment, with positive i…

Traditional vs. sliding-joint masonry infilled frames: Seismic reliability and EAL

2020

Abstract In reinforced concrete (RC) multi-storey buildings, the important role of the seismic interaction of structural frames with masonry infills has been revealed by several earthquakes and investigated by many authors. Recently, several innovative infill solutions have been proposed to mitigate such interaction, which could result in widespread damage in both the masonry and the RC structure and sometimes jeopardize the building stability and the occupants’ safety. One solution consists in the partitioning of the masonry infill into several sub-panels, relatively sliding along specific joints. This paper investigates the seismic assessment of this technological solution in the framewor…

A Dynamic Simulation Approach to Frame Drivers and Implications of Corruption Practices on Firm Performance

2014

Corruption is a multifaceted socio-economic phenomenon widely spread – although with different intensity – all around the world. Many studies on corruption have been conducted at a country-level, but relatively little effort has been placed in evaluating its implications, in terms of both financial and competitive performance, at a firm-level. Therefore, this paper aims at exploring the causal relationships underlying the effect of corruption on firm performance in order to show the different scenarios that may emerge from the combination between external (i.e., contextual conditions) and internal (i.e., organizational characteristics) forces that drive corruption. To this end, we adopt a D…

Detection and Discrimination of Inter-Turn Short Circuit and Demagnetization Faults in PMSMs Based on Structural Analysis

2021

This paper presents a fault diagnosis method based on structural analysis of permanent magnet synchronous motors (PMSMs), focusing on detecting and discriminating two of the most common faults in PMSMs, namely demagnetization and inter-turn short circuit faults. The structural analysis technique uses the dynamic mathematical model of the PMSM in matrix form to evaluate the system’s structural model. After obtaining the analytical redundancy using the over-determined part of the system, it is divided into redundant testable sub-models. Four structured residuals are designed to detect and isolate the investigated faults, which are applied to the system in different time intervals. Finally, th…

Reference-Plane Invariant Method for Measuring Electromagnetic Parameters of Materials

2010

This paper presents a simple and effective wideband method for the determination of material properties, such as the complex index of refraction and the complex permittivity and permeability. The method is explicit (non-iterative) and reference-plane invariant: it uses a certain combination of scattering parameters in conjunction with group-velocity data. This technique can be used to characterize both dielectric and magnetic materials. The proposed method is verified experimentally within a frequency range between 2 to 18 GHz on polytetrafluoroethylene and polyvinylchloride samples. A comprehensive error and stability analysis reveals that, similar to other methods based on transmission/re…
