What is lost when a language dies?
Authors: Søgaard Anders 
Published: March 2024

Abstract
Nowak argues that the problem with language loss is not linguists’ loss of data or that the loss of a language is often a result of discrimination against its speakers. Instead, the real problem is its speakers’ loss of illocutionary force. I argue that Nowak’s argument rests on two premises that are both empirically unjustified: that cultural knowledge is a prerequisite for illocutionary force, and that language is a prerequisite for illocutionary force. Languages are among the most fascinating accomplishments of mankind, surpassing Machu Picchu and the Great Wall of China in the eyes of many. I think language loss is comparable to loss of species. The intuition that the death of a language is a significant event, reflects that: Something that evolved gradually over hundreds of years, passed on through hundreds of generations and thousands of individual speakers, is irreversibly gone, once and for all. The illocutionary force of its individual speakers is not.

Abstract
This study aims to investigate the effect of fiber diameter on the mechanical and water absorption characteristics of short bamboo fiber-reinforced polyester composites. Three different fiber sizes (180–250 µm, 250–500 µm, and 700–1000 µm) were used to prepare composites with varying fiber loadings of 10 wt.%, 20 wt.%, and 30 wt.%. The fabricated composites were cut to standard dimensions, and tension tests, impact tests, and water absorption tests were performed. Reproducible results were obtained, revealing that using fibers of smaller diameter (180–250 µm) increased the tensile strength of the composite by 20 % compared to composites with larger diameter fibers (700–1000 µm), while the tensile modulus showed a 22 % enhancement with decreasing fiber diameter. Composites with larger diameter fibers exhibited more defects (voids and matrix detachment), as revealed by SEM analysis of fractured surfaces. The impact strength of composites with a diameter size of 700–1000 µm increased by 33 % compared to composites reinforced with the smallest fiber diameter. Water absorption of the composites was also studied by long-term immersion in water, showing that water intake was high initially, reaching a saturation point after a certain time interval. The absorbed water values indicated that composites with the smallest diameter (180–250 µm) showed maximum water intake due to the creation of more water intake sites (increased interfacial area), while composites with the largest diameter fibers (700–1000 µm) exhibited the least water absorption as the interaction region between fibers and matrix was reduced.

Authors: Dashchenko Nataliia L. 
Published: March 2024

The artistic component of the literary-artistic and public-political magazine Literary Ternopil» (2008–2019) was formed by publications that show the current state of painting in the region through familiarization with the personalities of artists and their creative work. The article highlights and analyzes typical textual means of presenting the artist in the specialized section «Artist of the Number». As a result of the research, it was found that the text presentation is based on the involvement of elements of drawing, which are manifested in the depiction of heroes in action, retelling of life situations, depiction of the area, interiors, etc. The plot-compositional organization of the texts includes biographical, everyday, socio-political, historical, psychological contexts, to reflect which the authors provide data on education, places of creative work, participation in exhibitions, obtaining titles, cooperation with various artists, describe external signs, worldview and inner qualities of artists. Expressions of art critics, connoisseurs of painting, and artists themselves are used compositionally. The presenters of the artists are the titles of the publications in which the starting point of the image is formed. It remains constant or changes: it can be individual / collective, synchronous / diachronic, shift in space (natural environment, premises, native land, abroad), have an emotional / intellectual dimension, focus on a situation or involve a whole range of information. An important component of the presentation is the art history characteristic in combination with evaluative and figurative expressions. For this purpose, artistic means of speech and stylistically marked vocabulary (names of subjects of professional activity, artistic directions, styles, and techniques), names of famous Ukrainian artists, names of iconic paintings, their cycles, names of exhibitions, etc., are involved. All these aspects are aimed at reflecting the spiritual, intellectual, creative development of the artist.

Published: March 2024

Free vibrations of an inhomogeneous anisotropic, fluid-contacting cylindrical shell stiffened with inhomogeneous rods and rings are consider. The Hamilton – Ostrogradsky variation principle was used when solving the problem. It was accepted that the nonhomogeneity of rods and rings used in the strengthening change by the exponential law. The inhomogeneous of the cylindrical shell change by the linear law in the direction of the thickness. The fluid was accepted as ideal. Rigid contact condition between the rods and the cylindrical shell was considered. Using the contact conditions, the frequency equation was structured, the roots were found implemented by the numerical method and characteristically curves were built.

Aim. To study the changes of biventricular contractile function depending on the types of left ventricular involvement according to the speckle tracking echocardiography (STE).Material and methods. Of the 380 patients from the Prospective Registry of People Survived COVID-19 Pneumonia, the study included 85 patients, which can be followed-up — 3 months (visit 1) and 12 months (visit 2) after COVID-19 pneumonia (men — 68,2%; mean age — 50,6±10,9 years).At visit 2, patients with diffuse left ventricle (LV) involvement according to STE (visual involvement of ≥4 segments of the same LV level) comprised group I (n=27), patients with regional LV involvement (≥3 segments corresponding to anterior, circumflex or right coronary arteries) — group II (n=39), patients without visual LV involvement — group III (n=19).Results. The groups were comparable in main clinical, functional and echocardiographic (conventional) parameters 3 and 12 months after COVID-19 pneumonia, with the exception of sex and body mass index. STE in group I showed a significant decrease in global longitudinal strain (GLS) (-18,0±2,0% at visit 1 and -16,9±1,4% at visit 2, p=0,025) and LS of all LV levels; in group II — an increase in right ventricular free wall strain (RV FWS) (-22,8±3,2% and -24,0±2,6%, respectively, p=0,006); in group III — an increase in GLS (-19,3±2,3% and -21,2±1,9%, p=0,005), LS of basal and medium LV levels, RV FWS (-23,3±2,9% and -25,0±3,0%, p=0,033). In group I, a significant increase in affected LV segments was revealed (7,0 [5,0;9,0] and 9,0 [7,0;10,0], p=0,010), while in group III there was a decrease in their number (5,0 [3,0;6,0] and 10,0 [1,0;2,0], p<0,001). According to logistic regression, LV basal LS at visit 1 (odds ratio 0,420; 95% confidence interval 0,273-0,644; p<0,001) had an independent association with diffuse LV involvement at visit 2. When it decreases, <15,8% sensitivity and the specificity of this model in predicting diffuse LV involvement was 74,1% and 74,1%, respectively (AUC=0,807; p<0,001).Conclusion. Patients with diffuse LV involvement according to STE are characterized by suppression of global biventricular contractile function during 1-year follow-up.

Aim. To evaluate the early and long-term outcomes of heart transplantation (HT) at the Research Institute of the S. V. Ochapovsky Regional Clinical Hospital № 1.Material and methods. On the basis of the Research Institute of the S. V. Ochapovsky Regional Clinical Hospital № 1 from March 2010 to March 2023, 230 HTs were carried out. Among the patients, men predominated 86% (n=198), women — 14% (n=32). The mean age was 48,3±11,7 years. The reason for HT in 42,6% (n=98) was ischemic cardiomyopathy (ICM), in 40% (n=92) — dilated cardiomyopathy (DCM), while 17,4% were operated on for another cardiac pathology (n=40). All recipients underwent immunological examination, endomyocardial biopsy (EMB), 2D-speckle-tracking echocardiography (2D-STE), transthoracic echocardiography (TTE), coronary angiography (CAG), as well as a number of studies for early diagnosis of possible cancer complications.Results. Acute rejection during the first three years was detected in 77 recipients (42,5%), of which cellular rejection (grade ≥2, 3) and humoral rejection was verified in 49 and 28 recipients, respectively. During the entire follow-up period, de novo anti-human leukocyte antigen (HLA) antibodies were detected in 34 recipients in the posttransplantation period, of which 50% (n=17) and 35% (n=12) were diagnosed with humoral and cellular rejection, respectively. Of the 34 patients with anti-HLA antibodies, 11 (32%) died. All of them died due to a humoral rejection. The survival rate of patients with antibodies was lower (59%) than in patients without antibodies (66%), p=0,023. The annual survival rate of all patients after transplantation in our center was 83,1% (during the first year after transplantation, 30 and 9 patients died due to an acute rejection and infectious complications, respectively).Conclusion. Since the introduction and modification of immunosuppressive therapy regimens, tremendous progress has occurred, and the incidence of acute cellular rejection has decreased. However, the risk of humoral rejection and long-term complications remains one of the main reasons for graft failure.

Aim. To assess vascular age (VA) and the main cardiovascular risk factors (chronological age, body mass index (BMI), carotid-femoral pulse wave velocity (PWV), blood pressure (BP)) in women in the Moscow region.Material and methods. We assessed BP levels, BMI, PWV, and also calculate vascular age for women participating in the forum. BMI was calculated using the Quetelet index as weight divided by height squared (BMI=kg/m2). BP levels were measured in a sitting position three times on both arms, with the highest result recorded. PWV and vascular age were calculated using AngioScan01. The association between anthropometric measures, vascular stiffness, and VA differences was examined using multivariate linear regression, adjusting for traditional cardiovascular risk factors. Intergroup (systolic blood pressure <140 mm Hg and ≥140 mm Hg) comparisons of PWV and VA difference from actual were performed using a modified Welch's t-test.Results. The study involved 260 women. The mean age was 44,92±0,85 years (95% confidence interval (CI) 43,27-46,57), mean vascular age — 45,90±1,01 (95% CI 43,91-47,89), mean BMI — 23,383±0,66 kg/m2 (95% CI 22,046-24,720). Mean systolic BP was 127,63±1,89 mm Hg (95% CI 123,89-131,36), diastolic BP 80,031±0,93 (95% CI 78,20-81,86), mean PWV was 11,38±0,16 m/sec (95% CI 11,05-11,70). Analysis of the VA difference between women with BMI <25 kg/m2 (BMI1, n=93) and ≥25 kg/m2 (BMI2, n=67) revealed a significant difference in the calculated VA values (p=0,0002) between groups.Conclusion. Modern young women have high rates of vascular stiffness, which may determine the increase in morbidity and mortality rates in the working-age female population. The VA indicator predicts cardiovascular events and can be considered as an effective screening method for assessing cardiovascular risk, which is especially important for young patients.
Wrench-Slip Reversals and Structural Inversions: Cenozoic Slide-Rule Tectonics in Sundaland
Authors: Tjia H.D. 
Published: March 2024

DOI: 10.17014/ijog.v1i1.174Most of continental Southeast Asia, that is, Sundaland and Indosinia, achieved a relative tectonic stability by the beginning of the Cenozoic. Since then a strong tectonic activity in Sundaland has been restricted to existing regional fault zones and to regional slow, vertical crustal movements elsewhere that produced small to very large sedimentary basins. On the other hand, regional deformation of Indosinia as a consequence of ductile shearing has continued into the Paleogene. Since the Oligocene, the northern part of Sundaland and Indosinia have been extruded differentially towards southeast along the Red River, Wang Chao (or Mae Ping, or Tonle Sap), and Three Pagodas - Axial Malay fault zones. The initial cause has been attributed to hard collision between Subplate India with Megaplate Eurasia. Plate dynamics in the region have changed substantially since Mid-Miocene as to force wrench-slip reversals along the major fault zones in Sundaland as well as in Indosinia. Concomitant structural inversions are demonstrated on seismic sections. In the core of Sundaland, earlier transtensional wrenching was succeeded by transpressive strike-slip faulting that on major faults of the Malay Basin manifested in reversals of sense. From the Hinge-line fault eastward, the transtensional left wrench slip was succeeded by transpressional dextral slip, while in the region to its west the wrench-slip kinematics was an earlier transtensional right slip followed by transpressional left slip. In the Strait of Malacca and eastern margin of Sumatra, right-lateral wrenching in the Neogene has been common. In certain places it could be established a wrench-slip of transtensional character in Oligocene-Early Miocene, and the transpressional wrench movement occurred mainly during the Middle to Late Miocene. The remarkable coincidence of termination of spreading of the South China Basin in Langhian, and that of the West Philippine and Caroline basins during Mid-Miocene invites further study.
A Drowning Sunda Shelf Model during Last Glacial Maximum (LGM) and Holocene: A Review
Authors: Solihuddin Tubagus 
Published: March 2024

DOI: 10.17014/ijog.v1i2.182Rising sea levels since the Last Glacial Maximum (LGM), some ~20,000 years ago, has drowned the Sunda Shelf and generated the complex coastal morphology as seen today. The pattern of drowning of the shelf will be utilized to assess likely timing of shoreline displacements and the duration of shelf exposure during the postglacial sea level rise. From existing sea level records around Sunda Shelf region, “sea level curve” was assembled to reconstruct the shelf drowning events. A five stage drowning model is proposed, including 1) maximum exposure of the shelf at approximately 20,500 years Before Present (y.B.P.), when sea level had fallen to about -118 m below present sea level (bpl.), 2) melt water pulse (MWP) 1A at ~14,000 y.B.P. when sea level rose to about -80 m bpl., 3) melt water pulse (MWP) 1B at ~11,500 y.B.P., when sea level was predicted around -50 m bpl., 4) Early-Holocene at ~9,700 y.B.P, when sea level was predicted at about-30 m bpl, and 5) sea level high stand at ~4,000 y.B.P., when sea level jumped to approx. +5 m above present sea level (apl.). This study shows that the sea level fluctuated by more than 120 m at various times during LGM and Holocene. Also confirmed that sea level curve of Sunda Shelf seems to fit well when combined with sea level curve from Barbados, although the comparison remains controversial until now due to the considerable distinction of tectonic and hydro-isostatic settings.
Fault-Plane Markings as Displacement Sense Indicators
Authors: Djin Tjia Hong 
Published: March 2024

DOI:10.17014/ijog.v1i3.177In order to determine the sense of fault motion, older textbooks advise to stroke the fault surface parallel to its striations, or slickensides. The smoother touch is felt when one’s palm moved in the direction of the adjacent fault surface. Laboratory triaxial tests and abundant field evidence proved this ‘smoothness criterion’ of producing ambiguous results. The first published field evidence contradicting the criterion probably originated from the Lokulo area in Central Jawa over half a century ago. Similar findings from elsewhere around the world have also been printed. A practical nomenclature has since developed. The types of reliable fault-plane markings in various rock types are now known. Recognition of fault-movement sense is essential when outcrop size is limited such as in underground exploration and in trenches. In addition, the present article also shows examples how the sense of faulting is applied to arrive at determining structural evolution of a rock body. The method is readily applied to solve structural problems of more extensive geological terranes.

DOI:10.17014/ijog.v1i3.192The Triassic rocks of the (West) Timor Basin have been identified that was mainly deposited in the marine environment. The fine grained clastics and carbonate rocks of this Triassic marine facies are considered to be the most promising source rocks potential in this basin. In this paper we present geochemical and petrographic data from outcrop samples of the Triassic carbonate Aitutu Formation, due to emphasized the organic maturation, kerogen type of the organic matter and the origin of the organic matter. A representative of selected sample were subjected to the Rock-Eval Pyrolisis, vitrinite reflectance and thermal alteration index, bitumen extraction, were analyzed on the GC-MS. The samples were collected from marine deposit of the Triassic Sequence. The TOC values of the analyzed sample range between rich and rich organic richness (0.51% - 9.16%, wt.%, TOC), which consists mainly of type II and III kerogen and the organic matter consider to be predominantly oil/gas prone and gas prone potential. The thermal maturity assessed from Tmax, TAI, and vitrinite reflectance shows an immature to early peak mature stage of the organic matter. The GC-MS analyses of the biomarkers indicate mainly the organic matter derived from mixed source rocks facies containing alga debris and higher plant terrestrial origin.

Published: March 2024

DOI: 10.17014/ijog.v5i1.90The eruption of Kelud Volcano in 2007 was started with an increase in the seismic activity on September 2007. It was ended with a lava dome formation inside the crater lake on 3 November 2007. This phenomenon showed the change of eruption behavior compared to the last eruption on February 1990 that was an explosive one. Result from the GPS observation method during three periods, which are: April, August, and October 2008 showed that the vector displacement on each measured point was affected dominantly by structural geology forces as a crustal stabilisation after the last phase of November 2007 eruption. There was also a minor displacement as the result of magma migration around the points that were close to the lava dome. The magma migration occurred in a relatively shallow depth and was associated with an aseismic zone. The deformation that occurred as a result of magma migration toward the surface was calculated to determine the magma supply and magma injected. The result then was compared to illustrate a mechanism of deformation during April – October 2008. The comparison of magma supply and magma injected within these periods showed that the inflation still occurred, but it was not supported by a surface manifestation. This inflation could be false because of data discontinuity, or it is actually a part of deflation trend.

Published: March 2024

DOI: 10.17014/ijog.v5i1.92The sample studied was derived from the base of core MD 982156, one of the boreholes obtained during the IMAGES Expedition. The expedition was carried out as a research cooperation between Indonesia and French Governments using Marion Dufresne Research Vessel, belonging to IFRTP (French Institute for Polar Research). Within this sample, the phillipsite minerals were firstly found by the first author. Using SEM (Scanning Electron Microscope) at the magnification of x1,000 for group and up to x20,000 for individual photos, the nannoplanktons were shown to accumulate on the phillipsite minerals as a binding matrix. Different directions and velocity of the bottom current when the phillipsite minerals were originated, might have contributed in binding of the various mineral shapes. The calcareous nannoplankton in the studied area is preserved within the sediments between 3880 m to 3914 m depths below sea level (bsl). This interval possibly located between Lysocline and Carbonate Compensation Depth (CCD), is indicated by the presence of well preserved calcite minerals and calcareous nannoplankton within sediments. Discoaster multiradiatus, the dominant fossil within the sediments in the studied area, is Paleocene in age. Therefore, the binding of nannoplakton accumulation as a matrix of the phillipsite minerals occurred as a postgenetic deposition.
