Optimizing droop coefficients for minimum cost operation of islanded micro-grids
2017
This paper shows how minimum cost energy management can be carried out for islanded micro-grids considering an expanded state that also includes the system's frequency. Each of the configurations outputted by the energy management system at each hour are indeed technically sound and coherent from the point of view of generation-consumption balancing by exploiting a frequency dependent load flow algorithm. A Glow-worm Swarm Optimization (GSO) algorithm carried out in a 24 hour time frame provides optimized results. A test has been carried out for a residential PV-Storage-Microturbine islanded micro-grid to show the feasibility as well as the efficiency of the proposed approach and results ar…
The Advantages of Type III Scaphoid Nonunion Advanced Collapse (SNAC) Treatment With Partial Carpal Arthrodesis in the Dominant Hand: Results of 5-ye…
2018
Introduction The SNAC wrist (Scaphoid nonunion advanced collapse) is one of the complications following scaphoid fractures treated conservatively and one of the causes of wrist arthritis that the hand surgeon has to face most frequently. In these cases surgical management is usually warranted. Materials and methods In the set time frame of 6 years we treated 15 SNAC wrist cases. On average patients underwent surgery five years after the trauma. All patients were treated via dorsal incision with partial carpal arthrodesis and total scaphoidectomy, associated with denervation of the posterior interosseous nerves. A plaster cast was applied to all patients for 3 weeks postoperatively. In the p…
Effectiveness of hexavalent vaccines against invasive Haemophilus influenzae type b disease: Germany's experience after 5 years of licensure
2007
Summary Vaccine effectiveness (VE) was determined with a case-cohort approach using Cox regression. Cases with confirmed systemic Hib infections in children born from 1 August 2000 to 31 December 2004 were ascertained through two independent nationwide active surveillance systems. A representative cohort of 1303 children born in the same time frame was randomly sampled in a nationwide immunisation survey. Thirty cases were eligible for VE calculation; 19 were unvaccinated and 11 vaccinated with hexavalent vaccines. VE was 68.4% (95% CI: 19.0–87.6) for incomplete primary series and 90.4% (95% CI: 70.6–96.8) for the full primary series. For full immunisation VE was 100.0% (95% CI: 52.7–100.0)…
Four great magnalia of government. La riforma istituzionale di Henry Neville: un machiavelliano inglese alla corte di Cosimo III de’ Medici
2021
The tumultuous phase running from the beheading of Charles I to the Glorious Revolution is the time frame in which England goes through the crucial phases that will put an end to royal absolutism. One of the most authoritative intellectual figures of that founding historical moment of modern constitutionalism is Henry Neville, author of political and satirical pamphlets who, taking up the lesson of the ancients with the experience of “modern things”, published in 1680 the Plato Redivivus, a work that will consecrate him as a Republican political thinker. The treaty, written and published in the context of the Exclusion crisis, exhort Charles II to reduce his powers. The disease suffered by…
Granice romantyzmu w dziejach polskiej komedii według dziewiętnastowiecznej krytyki krajowej
2021
W polskiej krajowej krytyce literackiej i teatralnej XIX w., dokonującej już pewnych bilansów dorobku romantyzmu, pojęcia „komedii romantycznej” i „romantyzmu w komedii” służyły za środek do porównawczych analiz i historycznoliterackich periodyzacji, choć jednocześnie takie kwestie, jak semantyczna zawartość tych terminów czy granice czasowe określanego nimi zjawiska, nie były precyzowane ani nawet problematyzowane. Podjęta w niniejszym artykule próba rekonstrukcji ówczesnych niewypowiedzianych wyobrażeń o tych znaczeniach i granicach wiedzie w kierunku formuły chronologicznie rozpiętej między „kosmopolityzmem”, przypisywanym wtedy klasycystycznej komedii XVIII w. i zwalczonym rzekomo dopie…

Destination engagement on Facebook: Time and seasonality
2019
Abstract This paper studies the influence of time frames (posting day and posting time) and seasonality (low, medium and high) on positive/negative engagement in a Destination Management Organization (DMO) on Facebook. A content analysis was carried out on 639 posts, 178,913 audience reactions to such posts and 5330 comments. These posts were shared 45,194 times by the audience. The data analysis (regression analyses with optimal scaling) suggests that the best times to post are at 8 am , 10 am , 2 pm and 5 pm ; Thursday and Saturday are the best days to post, and the period before summer (from January to June) are the best months. These results have implications for DMOs and National T…
Change in subjective age among older people over an eight-year follow-up: 'getting older and feeling younger?'.
2006
The purpose of this prospective study was to describe changes in subjective age over an 8-year period among community-dwelling people aged 65 to 84 years in Finland. At the baseline 1155 respondents met study criteria and 451 of these participated in the follow-up study. Participants described in years the age they felt themselves to be (feel age) and their preferred age (ideal age). Discrepancy scores relative to chronological age were calculated for feel age and ideal age. No significant mean-level changes were observed in the age discrepancy scores over the 8-year time frame. The baseline discrepancy between chronological and feel age remained constant among 48% of the participants, with…
Consequences of the COVID-19 pandemic on children with a speech and language disorder and their therapy
2021
Background The COVID-19 pandemic caused massive restrictions in our daily life. Kindergartens and schools were closed (lockdown) and children were forced to pause their therapy. Materials and Methods We conducted a survey during August and October 2020 and asked parents of children with a speech and language disorder about their child's therapy during lockdown and their fears and sorrows associated with it. Results Parents of 39 children participated (age: 6,15 years (3,06 - 10,09)). 34 children received speech therapy before lockdown. This therapy was paused for 17 children during lockdown. The other 17 children still received speech therapy during lockdown with the following alterations: …
How Does the Type of Migration Influence the Social Functioning of Polish Migrants in the Culture of the Host Country?
2014
The aim of the project was to research the social functioning of labour migrants in the culture of the host country. We were interested in showing the relationship between the time-frame of migration and the dimensions of socio-cultural adaptation. The study was conducted on a N=105 sample of Poles working abroad. A link to an online questionnaire was sent to those who had worked abroad during the study. The subjects were Poles who migrated to various countries in Western Europe. The research was of a quantitative-qualitative nature. The tools used in the study included a measure of Job Satisfaction, a Core Self Evaluation Score, and a questionnaire assessing work abroad. The qualitative pa…
