W niniejszej pracy przedstawiono wyniki badań mineralogicznych próbek agatów, pobranych z utworów górnego eocenu. Okazy pochodzą z Egiptu, z Pustyni Zachodniej, z rejonu Qasr el Sagha, występują w stropie piasków Qena. Agaty to skupienia minerałów grupy kwarcu, które ujawniają wyraźną granicę ze skałą otaczającą, są przeświecające, lub półprzezroczyste. Ich geneza związana jest z procesami magmowymi lub pomagmowymi, choć zdarzają się też agaty utworzone w środowiskach sedymentacyjnych. Celem badań była próba wyjaśnienia genezy agatów z Egiptu, rozpoznanie odmian tworzącego je kwarcu oraz identyfikacja tlenków i wrostków barwiących. Przeprowadzono badania makroskopowe, mikroskopowe - przy pomocy mikroskopu optycznego oraz mikroskopu elektronowego, dokonano także analizy dystrybucji pierwiastków w mikroobszarze. Na podstawie badań stwierdzono, że w agatach przeważa wykrystalizowany kwarc, występuje także chalcedon. We wrostkach zidentyfikowano tlenki oraz wodorotlenki żelaza, manganu i tytanu. Zauważono także, że mikrostruktura agatów ma odzwierciedlenie w ich wyglądzie makroskopowym.

Biomineralogia zębów mumii egipskich
(2018) Pawlikowski, Maciej
In the literature so far, there has been little information on mineralogical studies of teeth from old cemeteries, such as the tombs of Egyptian mummies. This publication adds to the knowledge in the field of mineralogical studies regarding vital and posthumous changes in the teeth of the people of Old and New Kingdom of Egypt. It shows the phenomena occurring in historical teeth, which are similar to those occuring in modern times. The research was conducted on approximately a dozen teeth, and the publication presents only selected, particularly interesting phenomena.

Enhancing the GDEMs of Egypt using a surface subtraction approach
(Wydawnictwa AGH, 2022) El-Ashmawy, Nagwa; Al-Krargy, Essam
This paper proposes an enhancement approach to improve the accuracy of global Digital Elevation Models (GDEMs) in Egypt. The proposed approach is an empirical one that depends on subtracting the heights error from the original DEM. The research includes the evaluation and enhancement of SRTM-1 (SRTM v4.1), ASTER GDEM v2, and AW3D30 v2 GDEMs, in Egypt, using 980 well distributed GPS/levelling points, that cover the entire country. The GPS/levelling points are divided into 500 control and 390 check points. The results show that the root mean square error (RMSE) in the SRTM, ASTER and AW3D30 are 3.99 m, 8.81 m, and 2.98 m respectively. For enhancing purposes, two different approaches are used: a linear regression analysis approach, and the proposed empirical surface subtraction approach. The results of the linear regression analysis approach show that the accuracies are improved by 3%, 16%, and 3% for SRTM, ASTER and AW3D30 respectively. However, the accuracies are improved by 5%, 23%, and 16% for SRTM, ASTER and AW3D30 respectively when the proposed approach is followed. After using the proposed approach, the obtained accuracy of the enhanced DEM reached 2.5 m.

Geological reconstruction of occupation phases, Tell el Farcha archeological site, Kom W, Nile Delta, Egypt
(2010) Pawlikowski, Maciej
Proposed reconstruction of phenomena of occupation and abundance of west part of Tel el Farcha Archaeological site show the complexity of history of the site. This complexity combined with other local phenomena makes reconstruction of side history very complicated. On the other hand, one can see the proposed graphic method used in reconstruction and understanding the past useless.

Geology and geomorphology as reasons for location of archaeological sites, Egypt
(2010) Pawlikowski, Maciej
Geological investigation of archaeological sites conducted by the author from 1979 in a vast area from Upper Egypt up to the Delta are presented (Hierakonpolis, Armant, Qurna - Deir el-Bahari, el-Tarif, Fayum - Qasr el-Sagha, Tell el-Farkha) in the study. There are described general (united) geological profiles done on the basis of field observation of both archaeological and natural outcrops (a lot of archaeological as well as natural outcrops). Obtained data help to perform correlation of sediments between described sites and propose reconstruction of paleo-environment and climate conditions at the phase of Late Neolithic - Early Dynastic transition. The mentioned observation and reconstruction has led to conclusion, that at the phase of the transition climate was extremely dry. This dry climatic phase is the factor, that most probably constitute very difficult conditions for life and agriculture, which obligated the Egyptians to the reorganization of life, i.e. was the reason for creation of dynastic Egypt.

Konrad Pędziwiatr, »Przemiany islamizmów w Egipcie i Tunezji w cieniu Arabskiej Wiosny«, Zakład Wydawniczy Nomos, Kraków 2019, 298 s.
(Wydawnictwa AGH, 2020) Wach, Dominik
The review concerns a monograph on the transformation of Islamic movements in Egypt and Tunisia and their politicization, in particular after the Arab revolutions (»Arab Spring«). The monograph presents an interdisciplinary approach to the discussed issues, but concentrates in particular on the achievements of social movement studies as well as studies of political Islam. The strength of the reviewed publication is also the analysis of the material obtained by the author during field research and interviews with the leaders of the Islamic movements and experts in the field of political Islam. Thanks to numerous fragments of interviews quoted in the book, as well as the publication of some of them selected in full, it aspires to enter the canon of publications about Islamism and broadly speaking policies in the Middle East and North Africa. Right balance between theory and practice further increases the attractiveness of the book.

Micro-artefacts as indicators of human activity, Tell el Farcha archaeological site, the Nile Delta, Egypt
(2010) Pawlikowski, Maciej
The main aim of the studies was research performed in order to distinguish kinds and quantities of micro-artefacts occurring within a selected profile and in a selected trench of Tell El Farcha anthropogenic site was carried out. Micro-artifacts are those fragments of anthropogenic origin, which are smaller than 2,0 mm in size, so the fragments, which go through the sieve during sifting of the material at the site. They represented fragments of bones, burnt clay, fragments of charcoal and micro-flakes of flints resulting from treatment of stone tools. The obtained results were used to draw profiles and maps of their distribution within the profile and anthropogenic trench. Obtained results were used to reconstruction of human activity in the selected areas of the site.

Research of flint patina from the Eastern Desert of Egypt
(2014) Pawlikowski, Maciej ; Sęk, Mateusz Przemysław; Sitarz, Magdalena
The subject of patination of flint has been discussed in many scientific publications. The majority of research concentrates on the applicability of the criterion of patina thickness on determining the age of flint artefacts, as well as for studying the correlation of archaeological profiles. Detailed knowledge of the mechanisms of patination, both in terms of physical and chemical, as well as mineralogical processes, is necessary for the correct interpretation carried out for each archaeological site. The large number of factors affecting patination greatly complicates any analysis of these conditions. This publication presents the research results of desert patina developed on flint artefacts in the conditions of the Eastern Desert of Egypt. Studies indicate mineralogical and chemical variability of patina in different types of flint.

Wyniki badań mineralogicznych spalonej substancji organicznej - stanowisko archeologiczne Tell el Farkha, Delta Nilu, Egipt
(2017) Pawlikowski, Maciej
Substancje organiczne w stanowiskach zachowują się rzadko. Im starsze stanowiska tym mniej jest w nich substancji organicznych. Jedna z okoliczności sprzyjających jej zachowaniu jest spalenie bez dostępu powietrza, czyli zwęglenie. Badania tego typu materiału wymagają stosowania szeregu metod stosowanych m.in. w naukach mineralogicznych. Badania zwęglonych substancji ze stanowiska Tel el Fakha, które mają około 5 tyś. lat pozwoliły rozpoznać spaloną sieczkę zbożową, spalony chleb, dziegieć., spalone tkanki roślinne, spalone kości i ości ryb.
