Morphostructural Development of Gunungsewu Karst, Jawa Island
Authors: Tjia H. D. 
Published: March 2024

DOI: 10.17014/ijog.v8i2.157Gunungsewu Karst (also known as Sewu karst in the literature) is synonymous with morphology of a carbonate terrain dominated by hills crowned by accordant-level tops that developed in a humid tropical environment by comparatively more rapid dissolution and denudation. In addition, the hills are sinoid to cone-shaped. Surface drainage is negligible compared to subsurface water flow. Abandoned channel segments and spatial arrangements of karst hills have been found to correspond with fracture patterns that are genetically associated with the regional compression direction of Jawa Island. Images derived from space platforms show many landform patterns that were neither known from ground-based nor from aerial photograph study. Landforms arranged in ring, multi-ring, spiral, polygonal, and long linear to serpentine patterns are common beside the expected depressions of dolines, poljes, and uvalas. The orientations of the long linear ridges appear to change systematically from those near the coast to those located inland. These linear ridges are interpreted as depositional fronts, most likely representing breaker zones. The youngest depositional ridge fronts, located nearest to the present shoreline, are parallel to the geological strike of Jawa Island. Toward the island’s interior, linear depositional fronts deviate in orientation by as much as 40o. This is now interpreted to have resulted from counterclockwise rotation of the Gunungsewu microplate since the late Middle Miocene. Similar CCW rotations are indicated by the paleomagnetic orientations of igneous rocks located farther east in the southern range of the island. Active tectonics is expressed in stage-wise net uplift of Gunungsewu whereas regional tilting appears negligible. Stacked and often paired river terraces (thus suggesting land uplift) have been used to relatively date paleoarcheological finds. Very recent uplift on the coast show up in lazy-V limestone notch profiles, and occasionally by stacked notches. At the Klayar coast, slight northward tilt of a few degrees are expressed as counter-regional inclination of a subrecent abrasion platform.

DOI: 10.17014/ijog.v8i2.158The researched area, located in the Dieng Plateau, is included into the Holocene Dieng Volcanic Rock Unit. The regional structure in this area is originated from the major caldera with local fault having orientation of SE - NW. Surface manifestations found in the researched area are hot springs located in Bitingan, Sileri, Siglagah, Pulosari, Kaliputih, and Sikidang. Fumaroles occur in Candradimuka and Pagerkandang and mud pools are located in Sileri and Sikidang craters. Temperatures of the hot springs ranges from 43 C to 61 C, pH of 6 - 7, and their conductivity are of 38-78 MeV. The type of hotwater is a mixture of bicarbonate, sulfate, and chloride sulfate deriving from condensation of steam. Based on a relative composition of Cl-Li-B, the hot water is originated from four different reservoirs with different rock associations, while their reservoir temperatures vary from 225 C to 300 C.
Characteristics and Origin of Sedimentary-Related Manganese Layers in Timor Island, Indonesia

Published: March 2024

DOI: 10.17014/ijog.v8i4.169Sedimentary-related manganese layers have been discovered in South Central Timor Regency, Timor Island, Indonesia, which is tectonically active and being uplifted due to north-trending tectonic collision between Timor Island arc and Australian continental crust. The manganese layers of 2 to 10 cm-wide interbed with deep sea sedimentary rocks including reddish - reddish brown claystone, radiolarian chert, slate, marl as well as white and pinkish calcilutite of Nakfunu Formations. Stratigraphically, the rock formations are underlain by Bobonaro Formation. Two types of manganese ores found comprise manganese layers and manganese nodule. The manganese layers strongly deformed, lenticular, and segmented, are composed of manganite [MnO(OH)], groutite [MnO(OH)], pyrolusite (MnO2), lithioporite (Al,Li) MnO2(OH)2, and hollandite [Ba (Mn4+, Mn2+)8O16] associated with gangue minerals including calcite, quartz, limonite [FeO(OH)], hematite (Fe2O3), and barite (BaSO4). Whilst the nodule type is only composed of manganite and less limonite. Geochemically, the manganese layers have grade of 63 - 72 wt.% MnO, whereas the nodule one has grade of 63 - 69 wt.% MnO. Generally, iron in Mn ore is very low ranging from 0.2 to 1.54 wt.% Fe2O3, averaged 0.76 wt.%. Hence, Fe/Mn ratio which is very low (0.003 - 0.069), typically indicates a sedimentary origin, which is also supported by petrologic and petrographic data showing layering structure of manganite and lithioporite crystal/grain. Trace element geochemistry indicates that manganese ore was precipitated in a reduction condition. Rare earth element (REE) analysis of manganese ore shows an enrichment of cerium (Ce) suggesting that the ore is basically originated in a marine environment. The manganese nodule is interpreted to be formed by chemical concretion process of unsoluble metals (i.e. mangan, iron) in seawater (hydrogenous) and precipitated on deep sea bottom. On the other hand, the manganese layer is a detrital diagenetic deposit formed by Mn remobilization in seawater column, precipitated and sedimented on the deep sea bottom. Manganese layers have probably been influenced by ‘hydrothermal process’ of mud-volcano activities, proven by the presence of quartz and barite veinlets cutting the Mn layers, manganite recrystallization to be pyrolusite along veinlets cutting manganite and lithioporite layers, and the presence of pyrite and sulphur associated with Mn layers. Field data also exhibit that the significant manganese layers are mostly found around mud volcanoes. The closely spatial and genetic relationships between manganese layers and mud-volcanoes might also be an important guide for the exploration of Mn deposit in the region.

The impact of grand multiparity on late pregnancy and early labour, hospital-based study on Garhwal region, Uttarakhand
Authors: Kumari Samridhi , Chauhan Nidhi , Bansal Ashnoor 
Published: March 2024

Background: Grand multiparity has been associated with adverse outcome for both fetus and mother such as antepartum hemorrhage, malpresentation, caesarean section rate, postpartum hemorrhage, iron deficiency anemia, and a high perinatal mortality rate. This study aimed to estimate the proportion of the antenatal, intrapartum and perinatal complications outcomes related to grand multiparity.
Methods: This is a prospective observational study conducted during a period of 1 year from 2021 to 2022 in the department of obstetrics and gynaecology, Himalayan hospital, Jollygrant, Dehra Dun, Uttarakhand. 60 grand multiparous patients who delivered during this period was analysed. Mothers with fetus/neonates were assessed for antenatal and obstetrical complications, mode of delivery and post-partum complications.
Results: During the study period, majority of women were in age group 26-30 years (45%), from plain areas (60%), and hilly areas (40%), 85% patients delivered vaginally, while 15 patients delivered by lower segment caesarean section. The main indication of C section was previous 2 LSCS. Maternal complications noted were anemia (30%), preterm labour (23.3%), malpresentation (1.7%) and placenta previa was seen in 3.3% women. Atonic PPH was noted in 10% cases. In present study there was no maternal death reported among grand multipara. 61 babies were born, in which 1.6% neonates were still born. There were no perinatal deaths. 34.45% newborns were born with low birth weight.
Conclusions: Grand-multiparity is an obstetric risk factor. Proper antenatal care, education, properly timed caesarean section in selected cases would reduce the grand-multiparity associated adverse pregnancy outcomes.

Authors: Dossouvi Komla M. , Bakpatina-Batako Kpalma D. 
Published: March 2024

OBJECTIVES:The World Health Organization (WHO) has reported carbapenem-resistantEnterobacteriaceae(CRE), carbapenem-resistantAcinetobacter baumannii(CRAb), and carbapenem-resistantPseudomonas aeruginosa(CRPa) as critical priority pathogens for human health. Therefore, this study aimed to review clinical carbapenem resistance systematically and comprehensively in West Africa.DATA SOURCES:A total of 102 research articles on carbapenem resistance from the sixteen countries forming the West African region were included in this review.DATA SYNTHESIS:Carbapenem-resistant bacteria (CRB) were isolated mainly from urine 73/300 (24.3%) and pus/wounds of patients 69/300 (23%). The mean prevalence of CRB in West Africa was 4.6% (1902/41635), ranging from 1.6% to 18.6%. CRB identified were mainlyEscherichiaspp. (34/130; 26.1%),Klebsiellaspp. (27/130, 20.8%),Pseudomonasspp. (26/130, 20%), andAcinetobacterspp. (25/130; 19.2%). Bacteria isolated in West African countries produced carbapenemases that belong to the four Ambler classes and include 13 types. TheblaOXA-type (34/104; 32.7%),blaNDM(31/104; 29.8%), andblaVIM(13/104; 12.5%) were the most common carbapenemase genes. These genes are carried by plasmids, composite transposons, and integrons. The Kirby-Bauer disc diffusion method (74/172; 43.0%), PCR (38/172; 22.1%), and whole genome sequencing (17/172; 9.9%) were the most common methods for carbapenem resistance detection. The most reported alternative antibiotics active against CRB were amikacin, colistin, and fosfomycin.CONCLUSION:There is an urgent need to take synergistic action to delay, as much as possible, the occurrence of CRB epidemics in West Africa.

Published: March 2024

Abstract

Successful business and production in the clothing sector are based on JIT (Just in Time), QR (Quick Response), and TTM (Time to Market) strategies, in which the production process is organized as part of a team using the time-accuracy-quality model, with the main goal of reducing time (faster), increasing quality (better), and lowering costs (more valuable). The work in the technological process of sewing is determined by the kind and character of the workpiece, the type of sewing machine, the design of the workplace, and the work method. By applying the basic motions of the MTM-1 system, elaborated standard sets of hand suboperations and the RAV and ZAK method for determining machine-hand sewing times, it is possible to determine the time of technological operation. The MTM calculator tool was intended to make it simpler to identify work methods and time norms based on the MTM system. It calculates the production time for a technical sewing process
Addition of microbial consortium to the rice straw biomethanization: effect on specific methanogenic activity, kinetic and bacterial community

Published: March 2024

Abstract
The biomethanization of lignocellulosic residues is still an inefficient and complex process due to the lignin structures that hinder the hydrolysis step. Therefore, one of the strategies has been the application of biological treatments using cellulolytic microorganisms. The objective of this work was to evaluate a microbial consortium obtained from the technology of effective microorganisms and enriched with microorganisms isolated from different agricultural soils, for bioaugmentation and/or pretreatment strategies during the biomethanization of rice straw. A laboratory-scale experiment was carried out in batch reactors, using anaerobic sludge from swine manure as inoculum, following two strategies: i) pretreatment of rice straw during 48 h using the enriched microbial consortium (dilution 1:100), and ii) addition of this enriched microbial consortium (dilution 1:100) directly to the anaerobic reactors (bioaugmentation). The kinetic behavior of the digestion process was described through three models. As a result, the molecular characterization of the enriched microbial consortia showed 58 different bacterial species responsible for the positive effect obtained in bioaugmented and pretreated reactors. The abundance of anaerobic species and the different metabolic pathways supported the higher methane yields (290 LNCH4/kgVS), even after 30 days of digestion, influenced by the addition of enriched microorganism consortia. All the kinetic models applied in this study fitted well with the experimental cumulative methane yield data, although the modified Hill model showed the best fit in all cases. The methane yield obtained from the pretreatment and bioaugmentation strategies demonstrates that these biological methods are efficient in the degradation of lignocellulosic biomass.

Abstract

Background. Acute myocardial infarction (AMI) represents a major cause of morbidity and mortality worldwide. Metabolomics investigation may be useful in the AMI pathogenesis research.
Materials and methods. The article describes a comprehensive study of the AMI through the targeted metabolomic profiling. A total of 195 subjects were enrolled in the study, consisting of 68 AMI patients, 84 IHD patients and 43 non-CVD subjects. Metabolomic profiling was conducted, involving the quantitative analysis of 87 endogenous metabolites in plasma.
Results. We identified 36 significantly changed metabolites in AMI, which included increased cystathionine and dimethylglycine and the decreased asymmetric dimethylarginine (ADMA) and arginine. It was found, that patients with AMI had significantly lower concentration of short chain acylcarnitines as compared to IHD and non-CVD patient. In patients with AMI concentration of xanthurenic acid and 3-OH-kynurenine was significantly decreased, as compared to IHD patients and non-CVD subjects. Norepinephrine was significantly decreased in patients with AMI and IHD, whereas its end-product – vanillylmandelic acid (VMA) – significantly increased. Based on the differences in the constructed weighted correlation networks, there were found new significant ratios of the metabolites. Among 23 established significantly altered metabolite ratios 14 ratios between non-CVD vs AMI and 17 ratios between IHD vs AMI were found. 9 ratios between non-CVD vs AMI and IHD vs AMI and 2 ratios between non-CVD vs IHD vs AMI were coincided.
Conclusion. Obtained findings may pave the way for new insight of АMI pathogenesis and ultimately improving clinical outcomes.
