First century B.C.E. in the history of Aegean Greece it was an exceptionally gloomy period. Between 88 BC and 31 B.C.E. Rome's first war with Mithridates took place on its lands, and later three Roman civil wars ended here. The article is an attempt to look at these events from a Greek perspective. It shows how the fighting Romans used Greek human, financial and material resources, and what effects it had.

Abstract. The article presents the material type from which the conductors of the overhead power lines are produced influences on the size of the overhang and the tension. The aim of the calculations was to present the benefits of the mechanics of the cable resulting from the type of cable used. The analysis was performed for two types of cables: aluminium with steel core and aluminium with composite core, twice span power line section. 10 different conductor-to-strand coil, wind, icing, and temperature variations were included in the calculations. The string description was made by means of a chain curve, while the horizontal component H of the tension force was determined using the bisection method. The loads were collected in accordance with applicable Eurocode.

The paper presents the energy performance of a single-family house located in Domaszowice, the Kielce poviat. The analyzed object has been put into use in 2010 year. Due to the devices using non-renewable energy sources, installed in the building for the needs of hot tap water and central heating, for servicing, which human presence is necessary, two thermomodernizations were performed. The purpose of the calculations was to indicate the financial benefi ts, i.e. to reduce the costs of maintaining the home and to provide its residents with proper comfort of use of the building, bearing in mind also the health aspect. Changes have been proposed to reduce the demand for non-renewable primary energy of EP using renewable energy sources. As a result, the energy-efficient building that meets WT 2017 was obtained. The Certo 2015 program was used in the analysis.

Theophanes and Potamon of Mytilene, two Greek euergetes who sought to serve their home polis in a rapidly changing political landscape of the late Roman Republic and early Principate, took an active interest in the politics of the day and sought to lobby Roman elites on Mytilene’s behalf. Theophanes befriended and advised Pompey, contributing to Pompey’s decision to pardon and liberate Mytilene after the city’s ignominious participation in the Asiatic Vespers, whereas Potamon served as Mytilene’s ambassador in Rome, adroitly championing its city’s interests. Two politicians bettered Mytilene’s political status in the tumultuous period of transformation from a republic to an autocracy and ensured that the city maintained its freedom until the times of the Flavians.
