ABSTRACT
After dental extraction a physiological phenomenon of reabsorption of the dentoalveolar process is triggered, especially if periradicular lesions are present, which can sometimes be associated with oro-antral communication in the upper posterior maxilla. With the aim of proposing a minimally invasive approach, 19 patients undergoing tooth extraction in the postero-superior maxilla were recruited. All cases presented an oroantral communication with a diameter of 2-5 mm after tooth extraction and the alveolar process, in some cases, with a partial defect of one or more bony walls. In these cases, a single surgical procedure was used to preserve the alveolar ridge with an open barrier technique with exposed d-PTFE membrane. The bottom of the extraction socket was filled with a collagen fleece and the residual bone process reconstructed using a bio-material based on carbonate-apatite derived from porcine cancellous bone. After 6 months all patients were recalled and subjected to radiographic control associated to an implant-prosthetic rehabilitation plan. Data relating to the sinus health status and the average height and thickness of the regenerated bone were collected. Radiographic evaluation verified the integrity of the maxillary sinus floor with new bone formation, detecting a vertical bone dimension between 3.1mm and 7.4mm (average 5.13mm ± 1.15) and a horizontal thickness between 4.2mm and 9.6mm (average 6.86mm ± 1.55). The goal of this study was to highlight the advantage of managing an oro-antral communication and, at the same time, to obtain the preservation and regeneration of the alveolar bone crest. The open barrier technique appears to be effective for the minimally invasive management of the oro-antral communication up to 5mm in diameter in post-extraction sites, with a good regeneration of hard and soft tissue.

Sosyal ve Mistik Bir Dinî Hareket Olarak Mazdekizm
Authors: Meçin Mehmet Mekin 
Published: March 2024

Bu çalışmanın konusu Mazdek dini hareketinin ortaya çıkış sebepleri, Mazdek’in öğretileri ve bu hareketin hızla ortadan kaldırılmasının nedenlerini incelemektir. Konu Mazdek hakkında bilgiler veren İslam Tarihçileri ve bu tarihsel veriler ışığında araştırmalarını derinletirmiş müsteşriklerin eserlerinden istifade ederek hazırlanmıştır. Bu çalışmanın amacı günümüze kadar yeterince anlaşılmamış ya da yanlış anlaşılmış Mazdek ve öğretilerini tarafsız olarak ele almak ve bu dinî hareketin ortaya çıkış ve yok oluş sebeplerini arka planıyla birlikte ele alarak özgün bir araştırma ortaya koymaktır. Araştırma sırasında, Mazdek’in insanlara zühdü, tavsiye eden, metafizik âleme ve Allah'a inanan, ahlakı ve fazileti vaaz eden, et yemeyi bile doğru görmeyen bir zat olduğu ve rivayetlerden anlaşıldığı kadarıyla tasavvufi bir hayat veya nebevi bir çizgi izlediği anlaşılmıştır. Çalışmada Mazdek’in dünya hâkimiyetini ele almada Mani kadar karamsar ve kötümser olmadığı ve bu bakış açısının bir sonucu olarak bozulduğuna inandığı dine yeni bir yorum getirerek eşitlik sloganıyla bir isyan başlattığı ancak çileciliğe, arınmaya ve sosyal hiyerarşiye karşı katı tavrı, İran'ın kadim iktidar ruhuna yabancı geldiği ve bu yüzden İran’ın dünyayı terk etmeyi öneren bu tür mistik düşüncelerin hâkim olmasına izin vermediği tespit edilmiştir. Çalışmanın sonucunda, Mazdek’in Mani’ye yakın bir dinî izlek üzere olduğu, adalet ve eşitlik sloganlarıyla toplumun yoksul tabakasını yanına çekmeyi başardığı ancak riyazete ve zühde dayalı öğretilerinin dünya hâkimiyetine aday olan kadim İran din-devlet geleneğine ters düştüğü için ivedilikle ortadan kaldırıldığı anlaşılmıştır. Yine bu çalışmadan, Mazdek’in sanıldığı gibi kadın ve mal ortaklığı savunan bir komünist olmadığı, fazla mala sahip ve çok kadınla evli seçkin sınıfa karşı yoksul insanlar adına bir adalet ve eşitlik davetçisi olduğu sonucuna ulaşılmıştır.

The Delos Mutation: Interdisciplinary Entanglements between Biology and Architecture 1963 – 1975
<!--EndFragment-->
Authors: Halland Ingrid 
Published: March 2024

This article traces the interdisciplinary entanglement between biology and architecture at The Delos Symposion, a series of annual week-long architecture and urbanism symposia convened by architect and planner Constantinos Doxiadis (1913–1975), ten of which took place on a cruise ship in the Mediterranean Sea between 1963 and 1972. These Delos symposia stand out as a pioneering interdisciplinary initiative and a unique think-tank for future-oriented developments in both architectural theory and biology, united by a common interest in cybernetics. Biologist Conrad Hal Waddington (1905–1975), who attended all ten Delos gatherings, was a forerunner of such new developments in biology; at Delos he discussed how his ground-breaking theory of epigenetics would change how designers would build, plan, and conceptualize buildings and cities.
This article is a critical study of how Waddington’s epigenetic theory mutated into architecture and urban theory. First, I discuss Doxiadis’ holistic urban theory of ekistics in relation to Waddington’s epigenetic theory by focusing on the notion of open-endedness in the two theories. The article then argues that the discussions on planning and design at Delos affected Waddington’s thinking, changing a structural belief in planning into a post-structural disbelief in certitude. The interdisciplinary Delos discussions about planning and architecture triggered the scientist to turn toward aesthetics and ethical epistemology as a response to an uncertain future — a transmutation that impelled ethical and epistemological developments that still resonate in critical discourses in the humanities.

DOI:10.17014/ijog.v1i3.198To anticipate the increasing energy demand, additional data and information covering unconventional fossil fuels such as oil shale must be acquired to promote the usage of alternative energy sources to crude oil. The Talawi and Lubuktaruk regions situated within intra-montane Ombilin Basin, and the Kiliranjao assumed to be a small intra montane basin are occupied by Eo-Oligocene sediments of Sangkarewang and Kiliran Formations, respectively. Field activity, geochemical screening techniques, and organic petrographic analysis, supported by SEM mode, are methods used. Most of the oil shale sequence is typically of an organically rich-succession comprising predominantly well-bedded, laminated and fissile, brownish to dark grey organic-rich shale and mudstone rocks. The exinite macerals within oil shale comprise mainly Pediastrum-lamalginite with minor cutinite, resinite, liptodetrinite, sporinite, bituminite, and rare Botryococcus-telalginite. Therefore; the oil shale deposits can be described as “lamosites”. Minor vitrinite maceral is also recognized. TOC analysis on selected shale samples corresponds to a fair up to excellent category of source rock characterization. The hydrogen index (HI) for all samples shows a range of values from 207 - 864, and pyrolysis yield (PY) ranges from 2.67 to 79.72 mg HC/g rock. The kerogen is suggested to be of mixed Type II and Type I autochthonous materials such as alginite, with minor allochthonous substances. Oil samples collected appear to be positioned within more oil prone rather than gas prone. Thermal maturity of the oil shales gained from Tmax value and production index (PI) tends to show immature to marginally/early mature stage. A consistency in the thermal maturity level results by using both Tmax and vitrinite reflectance value is recognized. On the basis of SEM analysis, the oil shale has undergone a late eodiagenetic process. Thereby, overall, vitrinite reflectance agreeing with Tmax rates, are also consistent with the PI (production index) values and SEM result. By evaluating all the results of geochemical and organic petrological analyses conducted on shale lithologies (shale and mudstone), it can be concluded that the oil shales in those areas have a favourable potential for generation of shale oil or gas to be included as alternative energy resources in the future.

DOI: 10.17014/ijog.v6i3.124Baseflow of karst underground river is a dependable flow to recharge the underground flow within dry seasons. This research was conducted in Gilap Cave, located in the upper course of Bribin River. This location has a premeditated point for sustainable karst water along the Bribin River. The main objective of this study was to separate the components of Gilap underground river flow, with the intention on defining the proportion of baseflow component during the period of measurements. A water level data logger was installed during the period between 1 May 2006 and 31 March 2007 to determine the variation of water level during the dry season, rainy season, and when the prevalence of flood events. Subsequently, several times of discharge measurements at the time of high, medium, and low water level were carried out to define stage-discharge rating curve. Then, baseflow separation was conducted using automated baseflow separation by a digital filtering method. A digital filter value was obtained from a constant recession analysis of flood events all over the year, correlated with Maximum Baseflow Indices Value (BFImax) within karst aquifers. The result shows that during one year, 41 flood events occured in the Gilap Cave with digital filtering value of 0.996. In addition, the calculation of baseflow percentage performs that the overall value of the ratio is close to a number of around 80%. Meanwhile, the percentages within flood events vary between the range of 45-75%. From these figures, it generally confirms that flow from small fracture is still dominant to recharge dependable flow within the upper stream of Bribin River, especially in the dry season.

Published: March 2024

DOI: 10.17014/ijog.v7i1.134The studied area, situated in northeastern part of North Sulawesi Arm, is dominantly occupied by the Mahawu, Linau, Tompusu, and Kasurutan volcanic rocks. Using remote sensing data, such as landsat image, black and white panchromatic aerial photograph, and IFSAR image, morphology-origin unit and morphology lineament can be interpreted. Four morphology-origin units, those are Mahawu Volcano Complex, Intra-montane Plain structure, Linau Volcano Complex, and Lacustrine Plain are recognized. Furthermore, morphological lineament pattern was statistically processed to find out the general stress direction in the area to determine the probability of the structural morphology occurrence in the Mahawu Volcano Complex. The result shows that generally the development pattern of volcanic cones are irregular, except the Mahawu Volcano Complex showing a linear pattern. This lineament pattern is interpreted as a NW - SE fault pattern controlling the rise of magma. At least, two tectonic and two eruption periods occurred regularly at different time from the Quaternary age till the present.
Tsunami Characteristics along The Coast of Biak Island based on the 1996 Biak Tsunami Traces

Published: March 2024

DOI: 10.17014/ijog.v7i1.135Identification on tsunami traces had been conducted along the coast of Biak Island, Papua, to recognize the character of tsunami potential in this region, referring to the 1996 tsunami event. This study is to observe the influence of tsunami to the environment and tsunami character itself which can be learned from tsunami deposit. According to the 1996 Biak tsunami run up distributions, it can be observed that the maximum tsunami run up was found at the coast which has an undulating to steep morphology rather than other places which has a relatively flat one. The 1996 Biak Tsunami arrival times were approximately between 10 and 15 minutes, such as at the northern and southern coasts of Biak, except for the western one which is about 1 to 5 minutes. This was influenced by the local bathymetry and another possible source triggering tsunami such as a local submarine landslide. The number of tsunami waves were between 2 and 4, and the second one was usually the highest. Based on a sedimentological analysis, the 1996 tsunami deposit is characterized by the dominant coarse sand, while grain size distribution curve shows a character of transportation process similar to an ordinary beach process dominated by saltation current. The foraminifera fossil content tends to indicate that the tsunami deposit was derived from > 200 m seafloor depth (bathyal zone).
Limestone Diagenetic Records Based on Petrographic Data of Sentolo Formation at Hargorejo Traverse, Kokap, Kulonprogo
Authors: Maryanto Sigit 
Published: March 2024

DOI: 10.17014/ijog.v7i2.138Limestone diagenetic records of Sentolo Formation have been studied in order to trace the history of the geological processes after the deposition of the rocks. A stratigraphic measure traverse was made in Hargorejo Village, Kulonprogo District, to identify the petrological characteristics of the Sentolo Formation. Limestone samples were taken along this traverse, and were used for a petrographic analysis. The analysis of thirtyeight limestone samples shows that the type is dominated by bioclastic grainstones which have been affected by various kinds of diagenetic processes after the deposition. The diagenetic processes recorded under the polarization microscope include cementation, replacement, bioturbation, micritization, recrystallization, dolomitization, compaction, fracturing, and leaching.
Diagenetic Pattern in the Citarate Carbonate Rocks, Cilograng Area, Lebak Regency, Banten Province
Authors: Basuki N. I. , Wiyoga S. A. 
Published: March 2024

DOI: 10.17014/ijog.v7i3.142The carbonate sequence overlies conformably the tuffaceous sandstone unit, and in turn is conformably underlain by the tuff-sandstone unit, both of which are members of the Citarate Formation. The Citarate carbonate rocks were deposited in an open platform back reef environment, which was temporarily drowned by local sea level rise. Regional Middle Miocene deformation formed NNE-WSW trend faults and E-W trend folds in the researched area. This paper discusses the nature of diagenetic alteration of the Citarate carbonate rocks based on petrographic analyses of twenty surface samples. Carbonate rocks from bottom to top comprise algae packstone, packstone-grainstone, coral-algae packstone, and foraminifer wackestone-packstone. Fragments of coral, coralline red algae, and large foraminifera are the dominant bioclasts in most of the observed samples, whereas echinoids and bivalves are less abundant; they are set in a recrystallized micrite matrix. Planktonic foraminifera are abundant only in few samples. Fragments of plagioclase, igneous volcanic rocks, pyroclastic rocks (tuff), and much less abundant quartz are commonly present in all the studied samples. A generalized diagenesis includes early marine cementation by fibrous aragonite, compaction, aragonite dissolution and/or neomorphism, precipitation of equant-grained calcite cement in a phreatic environment, dissolution to form moldic porosities, dolomitization, the formation of stylolites and fractures, and precipitation of late ferroan calcite during burial. Multiple carbonate cements occur as pore-filling phases, with ferroan calcite cementation taking place during later-stage burial. Secondary porosities were formed during different stages in diagenetic processes, such as dissolution, dolomitization, and stylolite and fracture formations. Although precipitation of nonferroan and ferroan calcite cement occluded porosities, porosity enhancement during early selective dolomitization might still be significant. Current observations also revealed the presence of intraparticle, micro-vuggy, and fracture porosities in different samples.
Supergene Enriched, Intrusion Related Low Suphidation Deposit, Binebase-Bawone, North Sulawesi, Indonesia

DOI: 10.17014/ijog.v7i4.150Gold mineralization at East Asia Minerals’ Binebase Prospect on Sangihe Island displays controls to mineralization typical of other Pacific Rim Intrusion related low sulphidation systems. Better gold grades are localized on EW dilatant structures at the intersection of NW trending structural corridors. Mineralization at Binebase was previously interpreted as being hosted in a high sulphidation style of alteration system. This assumption was based on surface observations of alunite and what was thought to be residual vuggy silica. Recent observations indicate that the alunite is a supergene mineral in nature and that the vuggy silica is the boxworked remnants of silica + pyrite alteration. Precious metal grades decline moving away from feeder structures and there has been significant supergene enrichment of gold in the oxide zone. Exploration drilling completed in 2008 by East Asia Minerals Indonesia resulted in an inferred resource of approximately 835,000 oz of contained gold at a cut off grade of 0.25 g/t Au. This resource included both oxide and hypogene sulphide mineralization. Drilling was reinitiated in 2011 to change the inferred to indicated resource, that drilling programme continued at the time of this publication. Various geophysical techniques were employed at both prospect and regional scales to aid exploration. Ground magnetics defined hydrothermal alteration and magnetite destruction which was coincident with mineralization at both Binebase and Bawone and an Induced Polarisation survey also produced an anomaly which was coincident with disseminated fine sulphide associated with clay alteration within the hydrothermal alteration. The southern part of the island was covered by an airborne geophysical survey in an attempt to understand the regional structural controls on mineralization and to define additional areas of hydrothermal alteration.

DOI: 10.17014/ijog.v8i1.151Kaliwangu Formation cropping out around Sumedang area contains mollusk fossils dominated by gastropods and bivalves. In terms of sequence stratigraphy, each sedimentary cycle generally consists of four shell bed types: Early Transgressive Systems Tract (Early TST) deposited above an erosional surface or sequence boundary, that is characterized by shell disarticulation, trace fossils, gravelly content, no fossil orientation direction, and concretion at the bottom; Late Transgressive Systems Tract (Late TST) identified by articulated (conjoined) specimen in its life position, that shows a low level abration and fragmentation, adult specimen with complete shells, and variation of taxa; Early Highstand Systems Tract (Early HST) characterized by adult taxa that was found locally in their life position with individual articulation, juvenile specimens frequently occured; Late Highstand Systems Tract (Late HST) determined as multiple-event concentrations, disarticulated shell domination, and some carbon or amber intercalation indicating terrestrial influence. Shell bed identification done on this rock unit identified nineteen sedimentary cycles.
Seasonal Mean Variability of Coral-based Sea Surface Salinity from Simeulue, Mentawai, Bunaken, and Bali
Authors: Cahyarini Sri Yudawati 
Published: March 2024

DOI: 10.17014/ijog.v8i3.161Sea surface salinity is an important parameter in a climate study. Coral δ18O records δ18O seawater and sea surface temperature (SST). While, coral Sr/Ca records SST only commonly used in a paleoclimate study to reconstruct SST. Thus, paired coral δ18O and Sr/Ca can be used to reconstruct δ18O seawater. δ18O seawater and SSS is linearly correlated, thus reconstructed δ18O seawater further is used to reconstruct sea surface salinity (SSS). Instead of using coral Sr/Ca as SST recorder, paired model (grid) or measured SST data is used to reconstruct SSS. In this study, paired coral δ18O and grid SST data are presented to reconstruct SSS from several different locations across Indonesian sea i.e Simeulue, Mentawai, Bunaken, and Bali. Coral-based SSS reconstructions from those locations are then compared to the grid SSS in the seasonal mean scale. The result shows that annual mean variation of salinity for period of 1958-2008 in Mentawai and Simeulue is 33.25 psu and 33.26 psu respectively, while in Bunaken and Bali is 34.03 psu and 33.47 psu respectively. Correlation coefficient between coral salinity and salinity from model data in the seasonal/monthly mean scale is high i.e R = 0.62 - 0.83. Based on the monthly mean data, corals in the studied area strongly record SSS variation in the monthly or seasonal mean scale. In Mentawai and Simeulue waters, SSS variation is influenced strongly by monsoon. While, in addition to the monsoon, ocean advection also affects seasonal variability of SSS in the Bunaken and Bali waters.
