Breakeven Point

The present article reveals the essence of the breakeven point, as an indicator of performance analysis. It also exposes its essence and its calculation formulas. A case study, presenting two companies as research object is carried out, where one company deals with natural gas distribution and delivery, and the other one is a baking factory.

The concept of disaster resilience has received considerable attention in recent years and it is increasingly used as an approach for understanding the dynamics of natural disaster systems. No models are available in literature to measure the performance of natural gas network, therefore, in this paper, a new performance index measuring functionality of gas distribution network have been proposed to evaluate the resilience index of the entire network. It can be used for any type of natural or manmade hazard which might lead to the disruption of the system. The gas distribution network of the municipalities of Introdacqua and Sulmona, two small towns in the center of Italy which were affected by 2009 earthquake have been used as case study. Together the pipeline network covers an area of 136 km2, with 3 M/R stations and 16 regulation groups. The software SynerGEE has been used to simulate different scenario events. The numerical results showed that, during emergency, to ensure an acceptable delivery service, it is crucial to guarantee the functionality of the medium pressure gas distribution network. Instead to improve resilience of the entire network the best retrofit strategy is to include emergency shutoff valves along the pipes.

Performance ratio is one of the indicators used to describe the effectiveness of the PV systems. The sustainability of the PV system year after year as well as its reliability can be checked by measuring the performance ratio each year. This indicator will also enable us to carry out a comparison between the performances of different PV systems. In this paper, the performance ratios for five PV systems installed on the roof tops of some of PTUK university buildings have been calculated on monthly and yearly basis. The analysis has been carried out using the available data (energy production and solar irradiation) for the year 2019. It was found that the performance ratio has higher values for May and September in comparison with other months. On the other hand, its lowest values were obtained in winter months. This trend can be observed for all of the PV clusters on the five buildings.  When taking into account the overall system, the highest value for the performance ratio was 0.89, which was for September, whereas its lowest value of 0.70 was obtained in January. The performance ratio, which was calculated on yearly basis for the overall system, was found to be 0.80. When considering each building separately, the lowest value was 0.44 for the “Services” building whereas the highest value was 0.94 for the Science building.

Arms Export

At a time when the subject of arms embargoes and arms export control is arousing considerable interest both at home and abroad, it is not untimely to examine the system of control which has developed in one of the chief arms producing and exporting countries of the world—Great Britain. Much attention has been devoted to the alleged evils of the international traffic in arms, and to the desirability of an effective government control over all armaments exports. Little consideration, on the other hand, has been given by writers to the question of how such control should be administered by a government, and what measures are actually involved. Taking the experience of Great Britain as a case study, the writer proposes in the following pages to trace the development of arms export control in that country, to examine the ways in which it has been administered, and to point out some of the difficulties which have been encountered. The present article may be looked upon, therefore, as a case study in the broader subject of national controls over the export of war materials.

The One

On the one hand in recent years nature tourism (turystyka przyrodnicza) has constituted a significant part of the tourism industry, on the other it has caused many problems for researchers attempting to define the phenomenon. Should the tourism destination or its primary motivation determine its categorisation? Is there indeed a need when considering practice as well as theory? The authors of the article have attempted a discourse with both foreign and domestic literature and subsequently sought to find the perceived meaning of turystyka przyrodnicza (nature tourism) amongst students of Poznań University particularly those associated with the natural environment on their degree courses. The present article should be considered as a contribution to further work in this field theoretically as well as practically.
