ɸιλοκαλο⋯μέν τε γ⋯ρ μετ' εὐτελείας κα⋯ ɸιλοσοɸο⋯μεν ἄνευ μαλακίαας. πλούτῳ τε ἔργου μ⋯λλον καιῷ ἢ λόγου κόμπῳ χρώμεθα, κα⋯ τ⋯ πένεσθαι οὐχ ⋯μολοσεῖν τιν⋯ αἰσχρόν, ⋯λλ⋯ μ⋯ διαɸεύγειν ἔργῳ αἴσχιον ἔνι τε τοῖς αὐτοῖς οἰκείων ἄμα κα⋯ πολιτικ⋯ν ⋯πιμέλεια, κα⋯ ⋯τέροις πρ⋯ς ἔργα τετραμμένοις τ⋯ πολιτικ⋯ μ⋯ ⋯νδε⋯ς γν⋯ναι.J. Kakridis has seen in this famous passage a reflection of the popular debate, conducted most memorably by Amphion and Zethus in Euripides' Antiope and Callicles and Socrates in Plato's Gorgias, over the respective merits of the vita activa and vita contemplativa. Normally the intellectual is faulted as lazy and helpless, the politician as an ignorant busybody; yet Pericles, according to Kakridis, claims that Athenians avoid these faults and combine the traits of both lives at their best.This interpretation accords well with the idealism of the funeral oration, but it falters over what Pericles places between philosophy and politics, viz.πλο⋯τος. Kakridis must struggle to account for the transition directly from philosophy to wealth, on the assumption that πλούτῳ τε…χρώμεθα serves to amplify ἄνευ μαλακίας, while ἔνιτε…⋯πιμέλεια extends the description of the non-intellectual life from the private sphere of trade to the public one of politics (pp. 50–1).

Abstract This paper argues that the Encomium of Helen must be seen as a speech about the value and importance of wisdom in human life and not as much as one as about logos. Gorgias sustains his vision based on a certain intellectualism which reduces moral faults to intellectual errors. This intellectualist program comprises a rationalization of emotions and a commitment with a certain tradition that discriminates between a minority with knowledge and a majority with only opinion. The consequence for Helen is that she can be excused from her action at the expense of being reproached for her lack of wisdom and is thus relegated to the ignorant majority. Therefore, what is initially praise and an apology turns into severe blame. For this, I argue, the encomium can be qualified as an amusement (paignion). For the Encomium’s listeners the amusement becomes a challenge that demands they decipher the speech’s paradoxical character and appeal to their own wisdom to not be reproached like Helen. Thus the Encomium cannot be seen as a treaty nor as mere joke but rather as an intellectual agôn between the speech and the listener, which serves them “to arm the soul for contests of excellence”, as the epigram dedicated to Gorgias in Delfos says.

The segment has a rather complex geological structure. The Svydovets massif is characterized by a complex division of structural overthrust sheets – Dukliansky, Porkuletsky and Chornohirsky overthrusts. The northern part of the site is located in the Slavsko-Verkhovynsky subzone of the Krosno zone. The Dukliansky overthrust represents Svydivets and Blyznytsia subzones, the Porkuletsky overthrust represents the Luzhansky subzone, and Chornohirsky – Yalovychorsky or Hoverliansky subzones. Each overthrust sheet shows the presence of ridgelike anticlinal folds that are deformed by thrusts and faults in fold parts. The Krosno zone is blocked by the thrusts of the Dukliansky and Chornohirsky overthrust sheets. A significant area within the study segment is occupied by the Inner Gorgans (near the water divide), which are confined to the raised base of the Silesian sheet, where the Gorgan folds were formed. The main morphostructural element is the massive Bratkivsky ridge, whose structure is dominated by resistant rocks of the Paleocene and Eocene, in particular the sandstones of the Yamna and Vyhodsky suites. The territory of the Chorna Tysa basin upper part is located in a seismic zone where resonant earthquakes of magnitude 4-6 periodically occur. Slow tectonic movements in this area are +1.5 –2.0 mm per year. Apart from analyzing the geological structure of the Chorna Tysa basin segment, which is a promising area for recreation and touristic development, this paper aims to outline the possibilities of using the geological structure and relief to develop educational forms of tourism, including geotourism. It is most often the geological structure (tectonics, diversity of rocks, long history of geological development, formation of mountain relief, etc.) that creates attractive sites – picturesque landscapes, outcrops of rocks, peaks, relict landforms, waterfalls, gregots, i.e., massive rock stream accumulation, and others). It can thus be concluded that the geological structure is crucial in forming promising tourism and recreation proposals and in the development of prospective infrastructure. Therefore, it is imperative to keep in mind the geological structure and landforms, when planning the development of recreation and tourism. Key words: geological structure (tectonics and lithology); landform, recreation and tourism; geotourism; geotourism attractions; Chorna Tysa; Ukrainian Carpathians.

Frequency-domain full-waveform inversion (FWI) is potentially amenable to efficient processing of full-azimuth long-offset stationary-recording seabed acquisition carried out with a sparse layout of ocean-bottom nodes (OBNs) and broadband sources because the inversion can be performed with a few discrete frequencies. However, computing the solution of the forward (boundary-value) problem efficiently in the frequency domain with linear algebra solvers remains a challenge for large computational domains involving tens to hundreds of millions of parameters. We illustrate the feasibility of 3D frequency-domain FWI with a subset of the 2015/2016 Gorgon OBN data set in the North West Shelf, Australia. We solve the forward problem with the massively parallel multifrontal direct solver MUMPS, which includes four key features to reach high computational efficiency: an efficient parallelism combining message-passing interface and multithreading, block low-rank compression, mixed-precision arithmetic, and efficient processing of sparse sources. The Gorgon subdata set involves 650 OBNs that are processed as reciprocal sources and 400,000 sources. Monoparameter FWI for vertical wavespeed is performed in the viscoacoustic vertically transverse isotropic approximation with a classical frequency continuation approach proceeding from a starting frequency of 1.7 Hz to a final frequency of 13 Hz. The target covers an area ranging from 260 km2 (frequency ≥ 8.5 Hz) to 705 km2 (frequency ≤ 8.5 Hz) for a maximum depth of 8 km. Compared to the starting model, FWI dramatically improves the reconstruction of the bounding faults of the Gorgon horst at reservoir depths as well as several intrahorst faults and several horizons of the Mungaroo Formation down to a depth of 7 km. Seismic modeling reveals a good kinematic agreement between recorded and simulated data, but amplitude mismatches between the recorded and simulated reflection from the reservoir suggest elastic effects. Therefore, future works involve multiparameter reconstruction for density and attenuation before considering elastic FWI from hydrophone and geophone data.

The assessment of the strength parameters of geological formations in regional scale which encounters thousands of slopes is a complicated approach and time consuming and needs huge field work. This issue is an important research topic concerning the regional seismic-landslide susceptibility analysis or hazard zonation. An empirical regression model was presented to estimate the Geological Strength Index (GSI) with an implication on geological quadrangle of Gorgan region at Alborz mountains range (north of Iran). Two main sets of data were applied in this study: (1) geomorphological data including the slope height, aspect, and distance from faults and distance from thrusts and (2) the physical and mechanical properties of rocks including the unit weight, uniaxial compressive strength (σci), and the petrographic constant (mί) of intact rock. The first group was extracted from a 1 : 100,000 digital geologic map and 10 m digital elevation model (DEM) and the second group was obtained from the Hoek–Brown failure criterion recommended tables. Linear regression equations were generated applying data collected from 294 studied stations using SPSS software. The regression equation predicted GSI in terms of (1) the distance from faults, (2) the distance from thrusts, and (3) the uniaxial compressive strength (σci). The equation had an R2 value of 0.739 and thus fit well to the data. The new method in its present state was recommended for the estimation of the GSI values in regional scale conditions for the assessment of landslide susceptibility and hazard mapping or post events landslide occurrence prediction in the case of probable big earthquakes in Alborz area that is required for emergency responses. The results indicated that the estimation error was about ±30 while the average error was within +5 and −5 and average error percentage was about 3%.

The North West Shelf hydrodynamics pressure database, developed as part of the North West Shelf Hydrodynamics Project, currently contains 7,780 pressure data points and hundreds of stress, temperature and water salinity data. All data have been ranked using a newly developed quality-control system. Equivalent hydraulic head mapping (fluid potential energy analysis) to interpret fluid migration pathways, hydraulic barriers and conduits was shown to be a valid technique despite lateral and vertical fluid density variations. Pressureelevation analysis identified six major aquifer systems (hydrostratigraphic units) in the regional North West Shelf. On a regional scale, the general flow direction in the North West Shelf is from the basins’ depocentres towards the onshore and upwards to the shallower aquifer systems. Compaction-driven flow is the main driving force for fluid flow in the North West Shelf. Overpressured compartments in the Carnarvon Basin are leaking, not hydraulically isolated from the regional flow field, thus generating their own local flow system. In general, fluid flow within the hydrostratigraphic units is parallel to the trend of major fault systems, which act as barriers in the horizontal plane of the aquifer. However, local-scale hydrodynamic analysis has shown that faults can act as fluid conduits between hydrostratigraphic units providing vertical hydraulic communication (e.g. Mardie to Barrow aquifers). Case studies in the Harriet, Gorgon, Griffin, Goodwyn and Vulcan areas have shown that the migration paths can be very complex due to the hydraulic nature of the faults and the presence of overpressured compartments

This article shows that important questions remain to be answered about the topics the sophists studied and taught, and their views, both positive and negative, about truth, religion, and convention. The sophists are united more by common methods and attitudes than by common interests. All sophists, for example, challenged traditional thinking, often in ways that went far beyond questioning the existence of the gods, or the truth of traditional myths, or customary moral rules, all of which had been questioned before. Gorgias, for example argued that nothing exists; Protagoras found fault with Homer's Greek; and Antiphon presented arguments for the innocence of someone who seems obviously guilty. In challenging traditional views, the sophists liked to use deliberately provocative, sometimes paradoxical arguments that seem aimed at capturing the audience's attention rather than enlightening them.

Abstract Deep saline aquifers offer significant potential for CO2 storage, with successful small-scale projects worldwide and major initiatives such as Gorgon in their early stages. In Peninsular Malaysia (PM) the daily CO2 production rate is expected to reach to the tune of ∼480 to 570 MMscf once the high contaminant gas fields are put on development. Several depleted hydrocarbon fields in PM region have been studied in the past for potential storage of the CO2 to be produced. Previously studies have been conducted on various depleted hydrocarbon fields within the PM region to assess their suitability for storing the anticipated CO2 volume. Nevertheless, the limited storage capacity and availability of these depleted reservoirs necessitate the exploration of alternative solutions. The deep saline aquifers in Peninsular Malaysia emerge as a viable option, as they can address the existing storage capacity limitations and facilitate the efficient development of high contaminant gas fields in the region, thereby enabling expedited monetization efforts. A comprehensive screening matrix was devised to identify strategic saline aquifers, considering various factors such as fault density, presence of top seals, reservoir depth, thickness, extension, pressure, temperature, porosity, number of wells drilled, and data availability. This holistic approach enabled the identification of structures that met the screening criteria. Further analysis was conducted on these selected structures to determine their theoretical CO2 storage capacity. Based on the evaluated capacities and their potential for cluster development, the structures were ranked accordingly. This systematic process allowed for the identification and prioritization of saline aquifers with the greatest potential for CO2 storage and cluster development. This study involves the feasibility study of one such identified clusters comprising three drilled dry structures that were analyzed for their containment and capacity through extensive 3D data interpretation for generation of structural maps, mapping of major and minor faults, and attribute extraction, trap & seal analysis, faults & wells integrity analysis, 1D caprock integrity analysis, and effective storage capacity estimation through dynamic simulation. The study concluded that two out of the three studied structures are associated with high trap risks and may not be suitable for injection & long-term storage of CO2. Further their close proximity to the regional fault would limit their viability for being potential open aquifer systems. The third structure which has well defined trap, seal & reservoir was found to be associated with relatively low effective CO2 storage capacity as based on the current analysis the storage capacity estimation was restricted to only one of the stratigraphic intervals only. The adapted workflow and lessons learnt during this study can be applied to future saline aquifer screening studies involving dry wells in the region. This study further unfolds the necessity of adequate data availability to derisk the critical CO2 storage elements.

Abstract CO2 Storage in deep saline aquifers has potential and small-scale projects have been successful globally while some major projects like Gorgon are in their early phases. Several depleted hydrocarbon fields have been studied in Peninsular Malaysia for potential storage of ~480 to 570 MMscf of CO2 which will be produced daily once high contaminant gas fields will be brought into production. However, due to the limited storage capacity and late availability of such depleted reservoirs, it is necessary to investigate options that might address both storage capacity and timely availability for sequestering the produced CO2. Peninsular Malaysia's deep saline aquifers have the potential not only to address CO2 production in the region, but also to serve as regional CO2 sequestration hubs. With a holistic approach, a screening matrix was developed to identify the strategic drilled dry structures or saline aquifers. It comprised fault density, presence of top seal(s), reservoir depth, thickness and extension, pressure, temperature, porosity, number of wells drilled & their integrity, and data availability. Structures that met the screening criteria were further analyzed for their CO2 storage capacity based on reservoir pore volume, producible water and CO2 compression factor. They were subsequently ranked based on the evaluated capacities and associated containment & well-integrity risks. Further the feasibility of clustering multiple dry structures (within a ~20km radius) was evaluated for nodal development. Six potential candidates were discovered from the thirty-four screened drilled dry structures, with individual structures having theoretical storage capacities ranging from 0.5 to 23 Trillion Standard Cubic Feet (Tscf). Two possible clusters were also identified: with Cluster 1, comprising three structures with a potential storage volume range of 1.1 to 1.8 Tscf, and Cluster 2 comprising two structures with a storage capacity ranging between 1.9 to 7.2 Tscf. The study also emphasized the need for more detailed to establish the feasibility of identified storage sites. To date, detailed feasibility studies are being conducted on all these structures to narrow down the range of the storage capacities and to come up with an appraisal plan for additional data acquisition to reduce the uncertainties before these structures are taken up for Storage Development Planning studies. This is the first-ever screening & evaluation of drilled dry structures/saline aquifers for CO2 storage in the Peninsular Malaysia area. These identified saline aquifers have significant CO2 storage potential that can help unlock the hydrocarbon potential in the high contaminant gas fields in the region on time and cater to the regional CO2 management in Southeast Asia.
