Published: July 2022

This research aimed to increase the green space factor to mitigate flash flood effects on urban storm water runoff in the Ankara Mamak region and to minimize the damages by flash floods. The land use/cover map was first obtained by using the images of Sentinel-1, Sentinel-2, and PlanetScope satellites with the LIBSVM algorithm on the Google Earth Engine. The GSF value was then calculated and it was low (0.26) compared to world standards. This study was proposed as a solution for the flood disaster, using the extensive green roof scenario. After green roof conversion scenarios, the GSF value was recalculated. It was found to be above the minimum of green infrastructure that human settlements should achieve, regardless of density or land use (0.43). Offering high resolution images and the possibility of processing them via different algorithms of machine learning has revolutionized the environmental and urban-related studies as they help urban managers and planners to make decisions accurately and quickly.

Authors:   Azerbaijan State University of Oil and Industry, Mukhtarova Kh.Z.
Published: July 2022

Lower Kur depression is a known oil-gas generation basin, which is characterized with positive stratigraphic, lithologic-facies and structural-tectonic criteria of oil-gas bearing content. However, it is necessary to perform additional estimation of the perspectives of oil-gas bearing content of the south-west wing of the depression, based on the tectonic criteria, seismological parameters and the presence of reservoir rocks, hoods and traps in the geological section. According to the results of the detailed investigation of Kurovdagh-Neftchala belt via the geophysical methods, it was defined that the developed lithologically limited and stratigraphic traps in Sarkhanbeyli, Orta Mughan, Shargi Shorsulu and Babazanan areas have all signs of oil-gas bearing perspectives. These traps are located in not more than 4.5 km depth among the benches of Mesozoic paleorelief and Pliocene sediments covering them. Specifically the nonconformities occurring between these layers could play a significant role in the migration and accumulation of the hydrocarbons. It should be noted that the initial reservoirs formed in the process of deposition make the traps on the surface of nonconformities related to the sedimentation-stratigraphic type, which lie down to the surface of nonconformity. The studies have revealed similar traps in the deeper thinning horizons, which may be considered perspective in the presence of the reservoirs, reservoir rocks and oil generating formations as well.

Authors:   Azerbaijan State University of Oil and Industry, Jafarova Kh.T.
Published: July 2022

The pressure loss in cryogenic pipelines for the cases with one-phase flow is specified via known hydraulic formulas for general fluids. The stream of two-phase flow causes troubles for hydraulic calculation of cryogenic pipeline. There are three main types of cryogenic flow in the pipelines. First type is characterized with quite equal distribution of liquid throughout stream phase of gas (homogenous gas-liquid mixture), second type – with the structure of gas and fluid in separate layers, and the third one – with the motion of fluid in the ring part of pipe walls and high speed of gas in its central part. The paper offers a calculation formula for the estimation of hydraulic resistance (losses) for hydraulic calculation of multi-phase cryogenic pipelines in the presence of thermal exchange with environment when pressure losses are associated with the force of gravity and friction.

The heavier performs significant functions during the treatment of the drilling mud. The paper presents detailed information on the heavier applied, and their effect on the structural-mechanical and colloidal-chemical properties of the drilling mud types. The studies on the selection of the alternative heavier types instead of barite to prevent pore pollution of productive horizons have been conducted. It is shown that after the weighting of the drilling mud via the carbonate heavier, a sharp increase in the viscosity of the drilling mud appears, as a result of which adding a corresponding viscosity reducer into the mud composition becomes necessary. Using the catastrophe theory suggested by Rene Tom, the processes occurring in the drilling mud have been estimated. The shearing processes after adding the carbonate heavier into the drilling mud composition have been studied as well.

Published: July 2022

The paper presents the methods of penetration of the productive layer. It is noted that the wells in the layers with high thickness are of plane bed and hydrodynamically incomplete by the penetration degree. The formula for an accurate oil recovery rate for such wells has not been developed so far. However, the approximate inaccurate formulas with errors, in one of which a gamma-function is used are suggested. In the reference books, this function is presented in the form of a Table (i.e. tabulated). Due to the complicacy of obtained formula in the borehole set, the solution of theoretic tasks becomes difficult. The complicated filtration flow in the lower part of the deposit in the other approximate method was considered a hemispheric-radial simple flow. The details of the suggested accurate formula for the oil recovery rate of the wells are provided; the plane bottom hole of the well is substituted with an incurved hemispheric surface here. The deposit is divided into two parts: plane radial simple oil flow occurs in the upper part, and hemispheric-radial simple flow in the lower part of it. To obtain the formula for the accurate complete oil recovery rate of this well, two different stationary hydrodynamic tasks have been solved and summarized as well.

Authors:   Azerbaijan State University of Oil and Industry, Sultanova A.V.
Published: July 2022

It is well known that in most oil and gas producing regions including Tatarstan and Bashkiria (Russian Federation), Azerbaijan, Kazakhstan, etc., a significant part of produced liquid hydrocarbons consists of oils with abnormal rheological properties, which contain paraffin, asphaltenes, and resin. Such types of oils are related to those of abnormal or non-Newtonian. The paper studies the effect of skin-factor on the recovery of oil with abnormal properties. The features of such a well product are of viscous-plastic liquid nature with an initial shear gradient. It is shown that this system has properties different from non-Newtonian fluids. It is suggested to describe the effect of skin-zone in the system of the equation via the parameter of “skin-factor”, which changes in wide diapasons depending on the nature of pollution of the skin zone. After the specification of “skin factor”, additional measures are carried out in the well on the treatment of the bottom-hole zone (acid treatment, additional perforation, etc.), which will allow regulating the productivity of the operation well.

Published: July 2022

The paper reviews the stationary hydrodynamic task on the replacement of the incompressible viscous-plastic oil with the thickened water in the horizontal circular reservoir, in the centre of which a vertical oil well is operated. The formula of filtration rates in different zones, the oil recovery rate, current pressure, current pressure gradients, the pressure in the border of oil and thickened water, as well as the formula of the partial and full duration of oil motion in the reservoir have been developed using generalized Darcy filtration law. All hydrodynamic calculation formulas developed should be applied in the solution of various theoretic tasks on the development of such oil fields, as well as when planning the projects on the exploration of new oil fields. Moreover, using the well known analytical dependence between the average actual rate of fluid motion in the porous channels and filtration rate, the formulas for the time calculation of the fluid motion though the border, in one case - on its current position, in another one – from the saturation contour to the well, have been developed. The formula of the first case is applied in the isolation of the produced water flooded with the contour water (in the formation of liquid fingers) in the wells via the hydrodynamic method for the time calculation of repeated flooding after the implementation of the first cycle of corresponding measure, i.e. after the viscous oil, which is also viscous-plastic fluid in the formation conditions, is injected into the layer.

Beginning from 1970-1980s as a result of the studies carried out in Guba-Khachmaz region, the thermal waters with the temperature of more than 80 оC were revealed on the Earth surface. These waters are characterized with high recovery rate and have natrium-chloride chemical composition. The chemical composition of thermal waters change appropriately depending on the zone and depth. Thermal waters of Mesozoic (Cretaceous) complex with natrium-chloride composition in Cenozoic sedimentary complex (Upper Productive Series) transfer to the waters with sulfate-natrium composition. Such a geochemical approach is clearly reflected towards the deepening of the sedimentary complex of Productive Series of Khachmaz upland with regard to both anions and cations. Based on the indexes of high temperature and recovery rate, as well as on the parameters of permanent and temporary condition in touristic purposes, the construction of a health resort complex in the territory of Nabran on shore of the Caspian Sea is possible.

This paper examines the proximate composition of ten commonly used seasonings (named A, B, C, D, E, F, G, H, I and J) in Nigeria. The data for this study were collected from Eke-Awka market in Anambra State as a representative of Nigeria using the simple random sampling method. The techniques of Single-factor Analysis of Variance and Kruskal-Wallis Test (One-Way ANOVA on Ranks) were employed in this study; Proximate compositions across the seasonings were tested for constant variance and normality. The findings of this study showed that the proximate compositions across the seasonings lack evidence of equality in variance and also lacks normality. Furthermore, the results from the Kruskal-Wallis test, as an alternative nonparametric to Single-factor ANOVA, showed that there is statistically significant difference between the proximate compositions across the seasonings. The Dunn Kruskal-Wallis Multiple Comparison test showed an evidence of no significant difference in the mean percentage composition of the following pairs of the proximate compositions: Ash and Fat, Carbohydrate and Fat, Ash and Moisture, Carbohydrate and Moisture, and Moisture and Protein. Thus, this study shows that there is significant difference in the proximate compositions of seasonings in Nigeria.

Authors: Putri Dwi Sisca Kumala , Achadi Endang L. , Gunardi Hartono , Widodo Yekti
Published: July 2022

AIM: This study aimed to assess the consecutive 3-month length increment thresholds, by the first 6 months, to predict stunted at the age of 6 months.
METHODS: We analyzed data from the Bogor Longitudinal Study on Child Growth and Development in West Java, Indonesia. A total of 635 free of stunting at birth children were analyzed in this study. Early linear growth faltering, as the dependent variable, was the stunted at 6 months of age. The four thresholds of the consecutive 3-month length increment were considered in predicting stunted at the age of 6 months. The thresholds were a consecutive 3-month length increment below 25th percentile, 15th percentile, and 5th percentile of the WHO Child Growth Velocity Standard. The 4th threshold was generated from the Bogor Longitudinal Study sample and determined using receiver operating characteristic analysis. The sensitivity, specificity, PPV, and NPV of the thresholds were calculated.
RESULTS: Among the thresholds, the 25th percentile of the WHO Child Growth Velocity Standard generates the highest sensitivity. The ability of the 25th percentile threshold to correctly identify children who had stunting at 6 months of age is 56.7%. However, the children whose experience a consecutive 3-month length increment below 15th percentile had highest risk to become stunted at the age of 6 months, adjusted by sex, birthweight, and birth length.
CONCLUSION: A consecutive 3-month length increment could be beneficial as a tool in identifying infants at high risk of early linear growth failure in stunted prevalent population.
Working Station Model Based on Mathematic Model of Anthropometry for Embroidery Workers
Authors: Abdurrahmat Asep Suryana , Gustaman Rian Arie , Faturahman Yuldan
Published: July 2022

BACKGROUND: Often, the embroidery craftsmen do their work by ignoring the unbalance of their anthropometric size with the size of the tables and chairs used. This condition causes not ergonomic sitting position when they are working that will trigger variety of subjective complaints of craftsmen, especially in muscles and joints.

AIM: Conducted development research using 4D model (devine, design, develop, and disseminate) based on anthropometry size to build chair and table as more ergonomic work station for embroidery craftsmen.

METHODS: The first three stages are done by analyzing the compatibility of anthropometry of the body with the size of work station used by mathematical approach and laboratory scale test. The acceptance level of craftsmen on the prototype of work station model measures by technology accepted model that conducted on a public scale.

RESULTS: The result of this research is the establishment of more ergonomic prototype of work station model for embroidery craftsmen and based on the result of public scale examination of 180 embroidered craftsmen showed that 63% of respondents stated less subjective complaints of muscle and joint disorders at the shoulders, 71% subjective complaints of muscle and joint disorders in the upper arm, and respondents stated reduced subjective complaints of muscle and joint disorders in the 56% after using a new work station model.

CONCLUSION: However, it is still necessary to make improvements to the prototype of the work station model to be more ergonomic and to suppress the emergence of subjective complaints of muscle disorders and joints of embroidery craftsmen.
Comprendre les glaces polaires au 18 e siècle, les apports ambivalents de Buffon et de Bernardin de Saint-Pierre
Authors: Rémy Frédérique
Published: July 2022

Alors que les glaces polaires sont encore très peu connues, Buffon puis Bernardin de Saint-Pierre les introduisent dans l’argumentation scientifique. Buffon imagine que la Terre finira gelée, comme ses pôles et Bernardin construit un système délirant mais extrêmement cohérent, entièrement basé sur les glaces. Leurs hypothèses se sont révélées très vite erronées mais les deux ont su voir le rôle des glaces dans le système climatique, pour l’un, rôle témoin pour l’autre, rôle acteur.
Habiter la terre : une lecture de l’anthropocène à partir des écrits de Montesquieu
Authors: Larrère Catherine
Published: July 2022

Au livre XVIII de L’Esprit des lois , Montesquieu explique comment « Les hommes, par leurs soins et par de bonnes lois, ont rendu la terre plus propre à être leur demeure ». Non seulement Montesquieu y caractérise les relations à l’environnement d’une façon qu’il nous suffit d’inverser pour comprendre la situation actuelle, où les bienfaits d’autrefois sont devenus des méfaits, mais, dans un cas comme dans l’autre, il importe, si l’on veut comprendre ce que veut dire habiter la Terre, d’étudier, comme le fait Montesquieu, la façon dont s’entremêlent, sur le long terme, actions humaines et processus naturels. Nous pouvons alors saisir, à l’encontre de toute tentative de conquête et de maîtrise technique, qu’habiter, ce n’est jamais fabriquer. Cela demande des « soins » et de « bonnes lois ». Une écologie politique, en quelque sorte.
« Des lois dans le rapport qu’elles ont avec la nature du climat » : le savoir des lieux et le regard du législateur chez Montesquieu
Authors: de Casabianca Denis
Published: July 2022

Montesquieu est ordinairement présenté comme l’inventeur de la « théorie des climats ». Cette présentation issue d’une lecture critique de L’Esprit des lois occulte la place qu’occupe la perspective climatique dans l’ouvrage et comment elle s’articule avec son dessein politique. En examinant comment cette approche climatique est actualisée dans d’autres recherches antérieures à L’Esprit des lois , on découvre que c’est un sens des situations et de la convenance qui se forme dans cette attention aux intrications du physique et du moral, sens qui doit permettre d’éclairer l’intervention législatrice.
