Published: January 2022

Background: Liver cirrhosis leads to the abnormalities in liver function.
Objective: This study aimed to determine the C-reactive protein (CRP) and lipid profile in cirrhotic patients as well as their correlation with patients age and body mass index.
Methodology: This case- control study was conducted in the Chittagong Medical College Hospital and People’s Hospital Limited, Chattogram from October 2017 to March 2018 for a period of six months. Venous blood was collected from 25 patients and 25 controls after 8 hours overnight fasting. Inflammatory marker (CRP) and Serum lipid status were recorded for each participant.
Results: The mean serum C-reactive protein; total cholesterol; Triglycerides; High Density Lipoprotein and Low Density Lipoprotein level were 2.448 ± 1.174; 132.228 ± 15.352; 100.228 ± 20.564 mg/dl; 53.081 ± 9.994 mg/dl and 59.108 ± 18.634 mg/dl in cirrhotic patients. CRP value was significantly higher in patients compared to healthy individuals (p < 0.05). The extent of decreasing lipid profile (except HDL) was also significantly related to the progress in cirrhosis (p < 0.05). The positive correlation of age and BMI of patients were associated with CRP and various lipid variables.
Conclusion: The higher CRP value and extent of decreasing lipid profile (except HDL) in patients may serve as a baseline for further studies that required to determine the predictive values of lipid profiles as a means to estimate the extent of liver damage in cirrhotic patients.

Published: January 2022

Telah dilakukan penelitian untuk menentukan nilai momen magnet dan mengetahui hubungan diameter dalam pipa terhadap nilai momen magnet neodymium yang bergerak di dalam pipa aluminium dan kuningan dengan metode analisis video. Dipakai sistem pesawat atwood untuk merancang prosedur percobaan pengambilan data. Salah satu beban yang digantungkan di ujung tali direkam pergerakannya menggunakan kamera panasonic Hc-V30. Kemudian file video tersebut dianalisis menggunakan software Logger Pro. Dari analisis tersebut diperoleh grafik posisi fungsi waktu. Kemudian dipilih data yang menunjukkan bahwa magnet telah bergerak dengan kecepatan konstan. Nilai kemiringan dari grafik sama dengan nilai kecepatan terminal dari gerak magnet di dalam pipa. Nilai kecepatan terminal tersebut dapat digunakan untuk memperoleh nilai koefisien redaman magnetik. Kemudian nilai koefisien redaman magnetik yang diperoleh digunakan untuk memperoleh nilai momen magnetik. Dari penelitian yang telah dilakukan dapat disimpulkan bahwa nilai koefisien redaman magnetik berbanding terbalik dengan diameter dalam pipa dan berbanding lurus dengan suseptibilitas bahan. Nilai momen magnet berbanding lurus dengan diameter dalam pipa dan berbanding terbalik dengan koefisien konduktivitas bahan.
Ring structures of the Norilsk metallogenic district in neural network cluster analysis of geophysical data
Authors: Nikulin I. I. , Samsonov A. A. , Kuznetsov M. V. 
Published: January 2022

An integrated geophysical and mathematical model of the Norilsk metallogenic region has been built according to the authors’ method of automatic express interpretation of areal geophysical data. It consists of fifteen levels of hierarchy. The model is based on the use of the mathematical apparatus of fuzzy logic — artificial neural networks without a teacher using the method of self-organizing Kohonen maps. Formation of cluster groups is justified. Clusters characterize to the greatest extent possible connections between multidimensional geophysical data. The presence of relationships between them is analyzed by identifying correlation dependences. Analysis of various geophysical transformants using self-organizing Kohonen maps is carried out. A number of input indicators-representatives of their groups are determined, on the basis of which a geophysical-mathematical model is built. A model in the form of a two-dimensional map of clusters using fuzzy logic tools. Terminological sets were formed for each group of clusters. The form of membership functions of previously unknown geological objects is given according to new interpreted data. The calculated clusters according to the results of the study reflect the northwestern fragment of the basaltic magmatism fields of the trap formation, within which two ring structures have been distinguished. In the western part of the study area, the model ring structure reflects the Bolgokhtokhsky stock of granodiorites. The second, the Pyasinskaya ring structure, previously unknown, indicates the presence of a dome-shaped object at a great depth — a possible source of root zones of intrusions of the Norilsk complex. The conducted experimental study confirmed the adequacy of the constructed model and the effectiveness of its use for the purpose of express analysis of geophysical data and decision-making in geological prospecting tasks.

The Gydratny Fault, extending in SW-NE over 60 km, is situated in the central basin of Lake Baikal. This fault governs a distribution of hydrocarbon gas discharge zones on the lake bottom, many of them are hydrate-bearing. During the Class@Baikal-2019 expedition gas samples were obtained from bottom sediments along the fault zone, molecular and isotopic properties of the gases were studied. It is concluded that the fault zone is permeable for hydrocarbons and serves as an important fluid flow conduit from deep sources to the surface. The most intensive gas seepage was determined along the central and north-eastern segments of the fault zone where it is associated with the MSU hydrate-bearing structure and the Novosibirsk and Ukhan mud volcanoes. Within these structures the highest concentrations of methane and C2+ components were detected, the heaviest isotopic composition of methane carbon (–57‰ VPDB) were identified and near-surface gas hydrate accumulations were observed. The south-western segment of the fault is characterized by the lowest concentrations of gases in sediments with light carbon isotopic composition of methane (–76‰ VPDB).A dominant gas migration mechanism (advection or diffusion) in the upper part of the basin sedimentary section conditions the registered concentrations of methane and its homologues in sediments and their carbon isotopic composition. Diffusion and dispersion of migrated thermogenic gases and significant portion of microbial methane in seeping gases are characteristic for the areas where the fault is buried under relatively thick modern sediments. Focused gas migration followed by its focused discharge are specific for the areas where the fault propagates to the lake floor and is well-expressed in a bottom relief. Two models of hydrocarbon gases migration to the surface explaining the observed gas-geochemical characteristics of bottom sediments are described and discussed. Obtained results can help in enhancing interpretation of data of gas geochemical prospecting for offshore oil and gas.

Published: January 2022

Natural processes contradictive to the common organic (sedimentary and migrational) theory of oil formation were concluded to take place based on the study of the hydrocarbons-biomarkers distribution regularities at the molecular level in the dispersed organic matter of rocks, petroleum and kerogen thermolysis products.Here specific examples of the generation of oil (concentrated organic matter) directly in the reservoir, i.e. reduced scheme of naphthydogenesis, excluding the process of migration were presented. At the same time, these examples do not exclude the migration of organic matter from the «oil source strata», but are an exception that confirms the general rule. It was shown that the study of organic matter, organic carbon (TOC), chloroform-soluble bitumen, pyrolysis “Rock-Eval”, etc., necessarily supporting the conclusions with data from a detailed study of the hydrocarbon composition at the molecular level.
