    Opis:
    The 2017 season of archaeological excavation at the site of Tell el-Retaba in the Nile Delta in Egypt led to several interesting discoveries. Two of these concerned burials: a Hyksos tomb from the Second Intermediate Period, robbed but with some remains of the original furnishings, and pit burials from the early Eighteenth Dynasty, one of which was richly endowed with silver jewelry. Meriting note is the discovery of moats belonging to the defenses of the Nineteenth Dynasty fortress. Exploration of a crowded Third Intermediate Period settlement was continued.

    Opis:
    The excavation at Tell el-Retaba in 2014 and 2015 comprised three seasons of fieldwork, carried out in sectors of the site already opened in previous years. The earliest archaeological remains date from the Second Intermediate Period and represent a Hyksos settlement and cemetery. Ruins of an early Eighteenth Dynasty settlement, fortresses from the Nineteenth and Twentieth Dynasties and from the Third Intermediate Period settlement continued to be excavated as well. Of note are some archaeological remains from the 17th–19th centuries, presented for the first time in the fieldwork report.

    Opis:
    The sixth season of fieldwork of the Tell el-Retaba Archaeological Mission has brought a number of significant results. For the first time remains of a Hyksos settlement (beside the previously known cemetery) were uncovered. Exploration of a large, regularly planned building, divided into a number of standardized flats, brought new evidence for the reconstruction of the function and organization of a strongly fortified town, which existed on the site during the Twentieth Dynasty. Remains of a Third Intermediate Period settlement showed that after the New Kingdom there was a clear change in the settlement pattern in Tell el-Retaba.

    Excavations of the Polish–Slovak Archaeological Mission in Tell el-Retaba in 2016 were continued in the western part of the site, uncovering remains of domestic and funerary structures from the Second Intermediate Period in Area 4. Houses from the first half of the Eighteenth Dynasty were also investigated in this area. In Area 9, several houses from the Third Intermediate Period were explored and, for the first time, also substantial remains of a Late Period settlement, including at least one “tower house”.

    Opis:
    The Tell el-Retaba archaeological site is located at Wadi Tumilat, a shallow valley running from the Nile Delta to the Bitter Lakes. In ancient times, a route connecting Egypt with Syria-Palestine ran across the site. In the 13th century BC, during the rule of Ramesses II, a fortress surrounded by “Wall 1” was erected and in times of Ramesses III in the 12th century BC, a larger fortress surrounded by “Wall 2” and “Wall 3” was constructed. Using the finite element method (FEM) and ZSoil 2D&3D software, the wall heights were modelled and their soil-structure interaction was analysed. Strength of the wall depended on size and strength of bricks and mortar, brickwork, wall shape and foundation. Ancient builders using mud bricks must have known from practical experience the essentials of a wall construction, in which the height to width ratio was at 1.75 to 1.85. Moreover, they must have related the engineering properties of the material with the height of the construction and its purpose. The width to height ratio must have been used and related by ancient Egyptians to the ground resistance. Modelling has shown that, at wall width of 5 m, the foundation would have lost its stability at wall height of 13–14 m and bricks from the lower part of the wall would be destroyed. According to the undertaken assumptions, in order to retain stability, the wall height must have been limited to about 8–9 m.

    Opis:
    The archaeological site Tell el-Retaba in north-eastern Egypt, about 35 km to the west of Ismailia city, is located in the middle of Wadi Tumilat, a shallow valley running from the Nile Delta to the Bitter Lakes, along which flows the Suez Canal. In ancient times the valley was a route between Egypt and Syro-Palestine, strongly fortified in the New Kingdom times (16th–11th century BC). Mud bricks were analyzed from two parts of the Wall 1 (core of grey-brown bricks and inner extension of green bricks) in a fortress which existed during the Ramesses II times. Grain-size composition of the studied bricks was almost identical in both parts of the wall, suggesting the same source material for a production of brick. However, significant differences were observed in physical and mechanical properties (uni-axial compressive strength) in both types of bricks. Bricks from the core had lower bulk density, higher porosity and soak faster, whereas their resistance parameters were much lower than those of the bricks from the inner extension. The reason for such large differences in brick properties was a technology of their production, particularly proportion of components, water volume added during brick formation or density degree. Brick preparation and in consequence, physical-mechanical properties had direct influence on preservation of defensive structures during environmental changes related to changes of groundwater and surface water levels or of precipitation. Ancient Egyptians responsible for construction works in mud brick structures of the fortress must have had good knowledge and experience. This could be observed particularly for the heaviest and most important construction element that is the defensive wall, founded on well-densified deposits. It was also testified by higher resistance of green bricks from the inner extensions, which probably originated slightly later and were intended to reinforce a weaker core built of grey-brown bricks.

    Opis:
    Ograniczenie emisji gazów cieplarnianych i zwiększenie udziału energii elektrycznej z odnawialnych źródeł energii (OZE) w miksie energetycznym stanowią ogromne wyzwanie dla większości światowych gospodarek, w tym Polski. Ze względu na specyfikę produkcji energii z OZE – jej rozwój na dużą skalę nie jest możliwy bez rozwiniętych systemów wielkoskalowego magazynowania i bilansowania energii. Wodór może być wykorzystywany w nieuniknionej transformacji energetycznej jako źródło, nośnik lub magazyn (bufor) energii, stąd też dynamika rozwoju technologii wodorowych stale przybiera na sile. Istotną kwestią dla zapewnienia bezpieczeństwa podziemnego magazynu i ograniczenia ryzyka związanego z ucieczką/stratą magazynowanego wodoru jest uszczelnienie otworów wiertniczych z wykorzystaniem szczelnego zaczynu cementowego, tworzącego dobrej jakości kamień cementowy. W niniejszej pracy podjęto próbę oceny szczelności stwardniałych zaczynów cementowych opracowanych do celów uszczelniania odwiertów w podziemnych magazynach wodoru (PMW) zlokalizowanych w sczerpanych złożach gazu ziemnego. W badaniach rejestrowano natężenie przepływu wodoru, co pozwala na ocenę porównawczą poszczególnych próbek w kierunku najniższych wartości przepływu, odpowiadających najwyższej szczelności. Pomiary wykonywano w różnych warunkach ciśnienia (wysokie ciśnienie porowe, niskie ciśnienie porowe, wysokie ciśnienie różnicowe, niskie ciśnienie różnicowe) i temperatury (60°C, temperatura pokojowa). Ustalenie przepuszczalności stwardniałych zaczynów cementowych jest problematyczne ze względu na specyficzny charakter ośrodka porowatego, który to cechuje się niestabilnością parametrów w czasie i w trakcie suszenia ulega trwałym uszkodzeniom.
    Reducing greenhouse gas emissions and increasing the share of electricity from renewable energy sources (RES) in the energy mix is a huge challenge for most global economies, including Poland. Due to the specific nature of RES energy production, its large-scale development is not possible without developed large-scale energy storage and balancing systems. Hydrogen can be used in the inevitable energy transition both as a source, carrier or storage (buffer) of energy, hence the dynamics of hydrogen technology development is steadily gaining momentum. An important issue to ensure the safety of underground storage and to reduce the risk of escape/loss of stored hydrogen is the sealing of boreholes using a hydrogen tight cement. The present study attempts to assess the tightness of hardened cement slurries developed for sealing boreholes in underground hydrogen storage facilities located in depleted natural gas fields. Hydrogen flow rates were measured, allowing a comparative assessment of individual samples towards the lowest flow rates corresponding to the highest tightness. Determining the permeability of hardened cement slurries is problematic due to the specific nature of the porous medium, which is characterised by instability of parameters over time and is permanently damaged during drying.
