Trismus and reduced quality of life in patients with oral squamous cell carcinoma, who received post-operative radiotherapy alone or combined with chemotherapy

Introduction Oral cancer prevalence is increasing, while the 5 year survival is about 50%. The patients who survive often develop chronic oral complications and functional abnormalities after their oncological therapy [ 1 , 2 , 3 , 4 ]. Pain in the mouth, jaw and neck, xerostomia/dry mouth, sticky saliva, radiation caries, fibrosis, difficulties in mouth opening and trismus are among the most common chronic complications. Those problems and functional abnormalities are associated with difficulties in food and liquid intake, swallowing problems, with the

How the Management May Affect Dispersal of Slender Speedwell (Veronica filiformis Smith) in Meadows and Pastures

Abstract

Slender speedwell (Veronica filiformis Smith, family Plantaginaceae) is a non-native and invasive species of grassland in the Europe. The aim of the study was to test the ability of the growth and spreading in nine differently managed grasslands (mowing, mulching, grazing). The best survival was found in two-years mowed lots with fertilisation and in all lots with not permanent cattle pasture crops. There were found the highest number of survived plants and plants with big “rosette“ diameters. Number of survived plant for two seasons was 18 and total number of vegetative peaks per plant was 688. The potential for the spreading of such plant population is great. On the other hand, plants did not survived in lots with mulch treatment and in fenced lots with permanent cattle grazing.

QTc Dispersion and T-Wave Alternans as Predictors of Mortality in Dogs with Dilated Cardiomyopathy and Ventricular Tachycardia in Holter Monitoring. a Retrospective Study

Abstract

The study presents a comparison of the results received from dogs with dilated cardiomyopathy (DCM) that died during the first 30 d of observation and from dogs with DCM that survived the first 30 d after the ECG. No differences were noted in the duration of QT or QTc in healthy dogs and dogs with DCM. QTcd was significantly higher in dogs with DCM and in dogs with DCM, which did not survive over 30 d of observation and dogs with DCM that died after the 30th d of observation. The presence of T-wave alternans (TWA) was more frequently observed in dogs with DCM (85% of the dogs) that died in less than 30 d during the observation. QTcd and TWA seem to be a useful non-invasive diagnostic tool to anticipate the risk of cardiac death in dogs with DCM.

The Growing Pains of Community Radio in Africa
Emerging Lessons Towards Sustainability

Abstract

Community radio is considered as an intervention strategy of choice for deepening participation and community ownership. Donors have funded a proliferation of community radio projects in the Global South, prompted by stories attesting to the power of radio as a tool for social change. The evidence suggests that beyond empowering communities, community radio can catalyse behaviour change and impact positively on wider development outcomes. In practice, the record has been mixed, with sustainability a critical challenge. A recent evaluation found that radio stations created through top-down initiatives tend not to survive when external funding dries up. Where such stations do survive, their purpose often becomes different from what was originally intended. Only in a handful of cases have previously aid-dependent radio stations become sustainable. Informed by insights from practitioners, and evaluation reports and scholarly literature, this article draws some emerging lessons.

Stabilization of an epidemic model via an N-periodic approach

Abstract

We analyze the evolution of an infectious disease by combining different groups of a population when the route of transmission is via encounters with free-living virulent organisms that can survive for a long time outside the individual. This study involves matrix analysis of lower triangular block matrices and some of their spectral properties. We propose an N-periodic control strategy in order to stabilize the disease around the disease-free equilibrium point.

The Functioning of Small and Medium-Sized Enterprises in Conditions of Economic Stability

Abstract

Modern companies operate in an unstable environment. This requires management of the companies to undertake adjusting measures that will enable companies to survive and achieve competitive advantage. Increasing the risk of doing business has prompted the author to undertake empirical studies of the SME sector and to identify the types of risks faced by entrepreneurs. The article presents the results of empirical studies and contains conclusions that may serve as an advice for the SME sector

The Manuscripts Of Isaac Wetzlar’s Libes Briv

Abstract

Isaac Wetzlar’s Libes briv (1748/9) was not printed, but circulated in manuscript form. The manuscript transmission spans a period of at least 65 years. No autograph has survived. Nine manuscripts are known today, some of which have been heavily edited. The article discusses earlier research on the manuscripts, transmission and audience, textual variants, and the different titles under which the text was circulated.

The communist world from dawn till dusk. a political geography perspective

Abstract

The article presents the territorial evolution of the communist world from its beginning up until the present day. It argues that the communist world was created in 1917 and that it has survived the end of the Cold War. It shows various ways of understanding its nature in the past as well as in present times and shows the variability and ambiguity of the communist world, including its territorial dimension, thereby encouraging reflection and discussion.

Origin, Types, and Functioning of Chandeliers with Serpent Arms: From the Netherlands to Lithuania

Summary

Chandeliers with serpent arms held at the National Museum of Lithuania and the Lithuanian Art Museum are among the earliest found in Lithuania. Previous efforts to find chandeliers of similar décor in Latvia or Poland while collecting material on lighting fixtures in Lithuania and the neighbouring countries were unsuccessful. Due to that reason, it was thought that the spread of these chandeliers of extraordinary décor was limited to the territory of Lithuania. A closer and more thorough look into collections of Western European museums has revealed that the motif of an elegantly coiled snake on chandelier arms should be related to Hans Rogiers, a founder who worked in Amsterdam in 1598–1638.

In the article, the origin of chandeliers with serpent arms in Western Europe and the ways they could have possibly reached Lithuania are traced back for the first time. Specimens that survived or did not survive in Lithuania, their development and problems of dating are analysed. Their functioning space is explored and the subject of their symbolism is addressed. The article aims to present and evaluate the surviving chandeliers with serpent arms in Lithuania. In the research, instruments of formal, comparative, iconographic, and reconstructive analysis were used.
