The Infra-Getic Unit is a palaeogeographic unit, predestined by palaeotectonics. From the point of view of geological heritage, it represents a geosites framework. For the purpose of the correlation, the Serbian sections of Lukanja, Bogorodica Monastery, Rosomac and Senokos, as well as the Bulgarian sections of Komshtitsa, Gintsi, and Stanyantsi were used. The Jurassic sediments of the Infra-Getic Unit crop out on the southern slops of the Stara Planina Mountain in east Serbia and west Bulgaria. The Lower Jurassic started with continental and continental-marine sediments (clays and sandstones) (Lukanja clastics and Lukanja coal beds in Serbia and the Tuden Formation in Bulgaria) and continue with Lukanja quartz sandstones (Serbia) and the Kostina Formation (Bulgaria). These sediments are covered by Lukanja brachiopod beds and Lukanja limestones (Serbia) and the Romanov Dol, Ravna and Dolni Loukovit Members of the Ozirovo Formation (Bulgaria) predominantly consist of bioclastic limestones. The sedimentations follow with Lukanja belemnites-gryphaea beds (marls and clayey limestones), which in Bulgaria correspond to the Bukorovtsi Member (also marls and clayey limestones) of the Ozirovo Formation. The Middle Jurassic sedimentation started with black shales with Bossitra alpine. These sediments are individualized in Serbia as Senokos aleurolites and clays and in Bulgaria they are known as the Etropole Formation. In Serbia the section continues with sandstones called Vodenicki sandstones of Bajocian age, known in Bulgaria as the Dobrogled Member of the Polaten Formation. However, in Bulgaria, the age is Upper Bajocian-Lower Bathonian, and it cover the marls of the lower member (Gornobelotintsi Member) of the Bov Formation and is covered by the upper member - alternation of marls and clayey limestones - the Verenitsa Member of the Bov Formation. The Vodenicki sandstones-Dobrogled Member which ended their distribution in the section of Komshtitsa, to the east (in the Gintsi section), they are not represented - build a body of sandstones, a prodelta coming from the west to the east. The Bov Formation corresponds to the Senokos ammonite beds in east Serbia. The upper boundary of the Senokos ammonite beds and of the Bov Formation is sharp. It is covered by grey limestones of the Yavorec Formation in Bulgaria and by the Kamenica limestones in eastern Serbia. They are covered by grey or red nodular/lithoclastic limestones ("ammonitico rosso" type) of the Gintsi Formation in Bulgaria and the Pokrovenik ammonitic (acanthicum) limestones in Serbia. The Jurassic section in the Infra-Getic ended with grey micritic and lithoclastic limestones, which belong to the Rosomac and Rsovci limestones in east Serbia and to the Glozhene Formation in Bulgaria.

The Getic and Supra-Getic are palaeogeographic units in SE Serbia and SW Bulgaria. Based on the presence (in Eastern) or absence (in Western) of Lower Jurassic marine deposits, the Getic is divided into Eastern and Western. In the Eastern Getic, the Lower Jurassic sedimentation in SE Serbia is represented by the Vidlic Clastites covered by the Lukanja Coal Beds, Lukanja Quartz Sandstones, Lukanja Brachiopods Beds, Lukanja Marlstones, Lukanja Belemnitic-Gryphaean Beds and Lukanja Cephalopod Limestones; in SW Bulgaria, the sedimentation commenced with the Tuden Formation, followed by the Kostina Formation and the Ozirovo Formation with a few members. The Middle Jurassic in SE Serbia commenced with the Senokos Siltstones and Shales and the Gulenovci Beds, while in SW Bulgaria with black shales (the Etropole Formation), followed by marls and clayey limestones of the Bov Formation. The Middle Jurassic sediments are represented in the Western Getic of SE Serbia by the Kurilovo Clastites and the Kurilovo Limestones (synonym to Gumpina Limestones of KRA?TNER & KRSTIC 2003); in the Supra-Getic of SE Serbia they are formed by the Jerma Clastites and Jerma Limestones (synonym of the Gumpina Limestones). In SW Bulgaria the Middle Jurassic sediments are represented by the sandstones of the Gradets Formation and by the bioclastic limestones of the Polaten Formation. During the Callovian (Middle?) started the formation of a carbonate platform with micritic limestones. In SE Serbia, it is Basara Limestones, Vidlic Limestones, Beljanica and Zdrelo Limestones, and in SW Bulgarian, the Belediehan Formation of Callovian-Kimmeridgian p.p. age. Characteristic for the Supra- Getic is the formation of a few grabens with specific sedimentation: the Svetlya Graben (the Zhablyano and Ozirovo Formations) and the Lobosh Formation; the Treklyano Graben (the Dobridol and Sredorek Formations), and out of it - the Methohya and Sredorek Formation. During the Callovian-Kimmeridgian p.p., in the Svetlya Graben was sedimented the Lobosh Formation, horizontally passing into the Javorets and Gintsi Formations. During the latest Kimmeridgian-Tithonian commenced a big facial diversification: on the Getic in SE Serbia sedimented reef or sub-reef limestones (the Crni Vrh and Kucaj Reef Limestones), while in SW Bulgaria, the Slivnitsa Formation. On the Supra-Getic in SE Serbia formed Luznica Flysch and in SW Bulgaria pre-flysch of the Neshkovtsi Formation and siliciclastic flysch of the Kostel Formation.

The Baixo Alentejo Flysch Group (BAFG) is an important stratigraphic unit that covers over half of the South Portuguese Zone (SPZ) depositional area, and it is composed by three main tectono-stratigraphic units: the Mértola, Mira, and Brejeira formations. All of these formations contain significant thicknesses of black shales and have several wide areas with 0.81 wt.%, 0.91 wt.%, and 0.72 wt.% average total organic carbon (TOC) (respectively) and thermal maturation values within gas zones (overmature). This paper is considering new data from classical methods of organic geochemistry characterization, such as TOC, Rock–Eval pyrolysis, and organic petrography, to evaluate the unconventional petroleum system from the SPZ. A total of 53 samples were collected. From the stratigraphical point of view, TOC values seem to have a random distribution. The Rock–Eval parameters point out high thermal maturation compatible with gas window (overmature zone). The samples are dominated by gas-prone extremely hydrogen-depleted type III/IV kerogen, which no longer has the potential to generate and expel hydrocarbons. The petrographic analyses positioned the thermal evolution of these samples into the end of catagenesis to metagenesis (wet to dry gas zone), with values predominantly higher than 2 %Ro (dry gas zone). The presence of thermogenic hydrocarbon fluids characterized by previous papers indicate that the BAFG from SPZ represents a senile unconventional petroleum system, working nowadays basically as a gas reservoir.

AbstractCulture is a demanding word, particularly when it is used in the context of the contemporary academic discipline of international relations (IR). It is often employed in order to distinguish one identity from another, allegedly illuminating idiosyncrasies embedded in a particular society or group of people. The essentialized understanding of culture is also detectable in the case of the current debate on the non-Western international relations theories (IRT). Non-Western politicians and scholars often employ the term culture in order to distinguish their values from alleged Western values. However, culture has another important function mainly advanced by a left-wing Kyoto School philosopher Tosaka Jun, that is, culture as a mirror for critical reflection for morality (Tosaka, 1966). This article is based on Tosaka's argument that culture has an important function for moral reflection beyond that of a mere means to identify one's distinctiveness from the West, and it criticizes Japan's soft power diplomacy or the total absence of it from that point of view. It also argues that this absence is the result of the soft power discourse's over-simplified interpretation of culture that results in confrontation between the West and the rest, particularly when it is employed in non-Western IRT discourses. Towards the end, I examine Miyazaki Hayao's films,Princes Mononokein particular, as examples of cultural works facilitating a moment of critical reflection, and I extract embedded messages of relevance to critical reflection on contemporary IR literature, particularly non-Western literature.

Sinemurian phosphorites in southeastern British Columbia and southwestern Alberta conform with the "West Coast type" phosphorite depositional model. The model indicates that they were deposited on or near the Early Jurassic western cratonic margin, next to a sea or trough from which cold water upwelled. This suggests that the allochthonous terrane Quesnellia lay well offshore in Sinemurian time. The sea separating Quesnellia from North America was partly floored by oceanic crust ("Eastern Terrane") and partly by a thick sequence of rifted, continental terrace wedge rocks comprising the Purcell Supergroup and overlying Paleozoic sequence. This sequence must have been depressed sufficiently that access of upwelling deep currents to the phosphorite depositional area was not impeded.

  This study aimed to identify the role of educational media in meeting the scientific needs of students in light of the Corona pandemic from the point of view of Palestinian university students in the west bank and to achieve the objectives of the study the descriptive analytical approach was adopted and a questionnaire of (30) paragraphs (337) was developed and distributed among students of Palestinian universities in the West Bank, and then statistically processed using the Statistical Package for Social Science (SPSS.) Palestinian university students came up with a total average of (3.49 out of 5), and this result means that the role of educational media in meeting the scientific needs of students ranged from high to low. As it appeared, there were no statistically significant differences at the level of indication (0.05α=) in the average responses of the study sample members towards the role of educational media in meeting the scientific needs of students in the light of the corona crisis attributable to each of the variables (gender, university system) while there were differences attributable to both the variable (practical college and place of residence, based on the results of the study). The researchers recommended that educational media should focus on providing students with new experiences in their field of educational media and that all Palestinian universities should allocate more than one educational broadcast in order to provide opportunities for all students in all disciplines to learn.

More marvellous and more remarkable than the real conquests of Alexander are the stories circulated about him, and the legends which have clustered round his name and his exploits. The history of Alexander has, from a very early period, been embellished with legends and tales. They spread from nation to nation during the whole of the ancient times, and all through the Middle Ages. Many scholars have followed up the course of this dissemination of the fabulous history of Alexander. It would, therefore, be idle repetition of work admirably done by men like Zacher, Wesselofsky, Budge, and others, should I attempt it here. All interested in the legend of Alexander are familiar with those works, where also the fullest bibliographical information is to be found. I am concerned here with what may have appeared to some of these students as the bye-paths of the legend, and which, to my mind, has not received that attention which is due to it, from more than one point of view. Hitherto the histories of Alexander were divided into two categories; the first were those writings which pretended to give a true historical description of his life and adventures, to the exclusion of fabulous matter; the other included all those fabulous histories in which the true elements were smothered under a great mass of legendary matter, the chief representative of this class being the work ascribed to a certain Callisthenes. The study of the legend centred in the study of the vicissitudes to which this work of (Pseudo-) Callisthenes had been exposed, in the course of its dissemination from the East, probably from its native country, Egypt, to the countries of the West.

Literary studies can not be separated from the literary theory initiated and developed by “Western” scholars. Indonesian Literature also refers to these theories in interpreting and explaining literary works. This paper intends to ask the historical contextuality and the theoretical independence of Indonesian literature as a nation that has a historicity different from the West. The main offer in this paper is the importance of a theory called the theory of harmony-constitution. The important objectives of the theoretical point of view of the theory of harmony-the constitution are 1) all efforts to build an independent society and social justice, 2) a happy and safe condition, and hence the freedom that has been achieved should always encourage unity, sovereignty and prosperity, and 3) the acknowledgment “on the blessings of almighty God and by the noble driven.” Methodologically, the theory of harmony-constitution is based on semantics. This theory can be used to analyze social and cultural issues, but in the case of this paper will be tested to study literary works, especially the poetry of Chairil Anwar.

Abstract Substantial numbers of the nautilid Cenoceras occur in a stratigraphically limited horizon within the upper part of the Lower Jurassic (Sinemurian Stage) Blue Lias Formation at Watchet on the West Somerset Coast (United Kingdom). Individual nautilid conchs are associated with clusters of encrusting organisms (sclerobionts) forming ‘islands’ that may have been raised slightly above the surrounding substrate. Despite the relatively large numbers of nautilid conchs involved, detailed investigation of their preservation suggests that their accumulation reflects a reduction in sedimentation rates rather than an influx of empty conches or moribund animals. Throughout those horizons in which nautilids are present in relative abundance, the remains of ammonites are subordinate or rare. The reason for this unclear, and preferential dissolution of ammonite conchs during their burial does seem to provide a satisfactory solution to the problem.
