¿Qué es la Medina y qué supone en una techumbre de mocárabes?
Authors: Piñuela García Mila
Published: January 2024

Encontramos en el Occidente islámico techos de mocárabes con trazados de medina similares. En el análisis de ese “tipo de trazado similar” nos fijamos en tres techumbres de madera y observamos cómo a lo largo del tiempo la medina ha evolucionado, pero no tanto en su trazado como en el cometido que tiene dentro del proceso constructivo. Por otro lado, ciertos indicios nos llevan a pensar que esta misma evolución también se dio en ejemplos de yeso.

Published: January 2024

This retrospective study, conducted between October 2022 and October 2023 at Maroof International Hospital & Life Care International Hospital in Pakistan, aimed to assess the impact of anemia on neonatal and maternal outcomes in teenage pregnancies. The study included 585 pregnant women aged 13-19 years, with data collected on various parameters such as demographic details, pregnancy-related information, hemoglobin levels during the last trimester, birth weight, gestational age at birth, obstetric complications, neonatal intensive care admissions, and Apgar scores. Among the 585 participants, 212 (36.2%) were identified as having anemia. Further classification revealed that 57.5% experienced mild anemia, 39% had moderate anemia, and 3.5% had severe anemia. Educational status and irregularities in antepartum care showed significant differences between anemic and non-anemic groups (P < 0.05). Anemia was notably higher in women with lower education levels and irregular antenatal care. The study found that anemia significantly increased the risks of postpartum hemorrhage (P=0.005) and postpartum transfusion (P< 0.001). Additionally, infants born to anemic mothers exhibited a significantly higher rate of neonatal intensive care unit (NICU) admission (P<0.001). Maternal anemia was also significantly associated with low birth weight, small for gestational age (SGA), and preterm delivery. However, anemia had no significant impact on Apgar scores. In conclusion, the study underscores the prevalence of anemia in teenage pregnancies and emphasizes its adverse effects on both fetal and maternal outcomes.

A Traditional and Non-traditional Export Performance Assessment: An empirical examination of factors enhancing the competitiveness of Zambia's Exports
Authors: Nsakaza Kalimanshi , Kanchebele Emmanuel
Published: January 2024

This study examined the performance of traditional and non-traditional exports and further analyzed the factors that determine their performance in Zambia using a time series analysis (1960 and 2021). With the aid of the Vector error correction model, the study found that increases in the Real GDP, and Foreign Direct Investment of Zambia positively and significantly affected the volume of exports. In the analysis of aggregate exports, the non-significance of the relative price elasticity (Foreign Exchange rate) suggests that trade policies that concentrate overly on expenditure switching such as tariff and non-tariff restrictions or devaluations do not effectively assist trade policy reform efforts. The study thus recommends the need to promote inclusiveness, diversification and growth in investment towards the production of export commodities, particularly through the Multi-Facility Economic Zones by providing incentives to expand export diversification and growth at the local level through revising the Fiscal and non-Fiscal incentive thresholds in MFEZs to reflect the financing capacity of local investors.

Prospects for the use of flow diverter technologies at the Alibekmola oil field
Authors: Musharova Darya A.
Published: January 2024

Background: The process of oil production from low-permeability reservoirs has some features and is associated with a number of problems. The main problem is the lack of involvement in the active development of oil reserves in low-permeability zones. Most design documents for the development of low-permeability carbonate reservoirs recommend conventional water injection, which leads to rapid water encroachment of production wells due to water breakthrough from the injection well to the production well through the high-permeability layers or fractures.

Aim: In the conditions of low-permeability reservoirs of carbonate deposits, there is a need to search for new technologies and development methods that will ensure the economic viability of field development at a late stage.

Materials and methods: One of the promising technologies that help reduce the level of water cut and involve in the development of an inactive matrix zone low-permeability fractured reservoirs are flow diverter technologies aimed at increasing the sweeping efficiency of productive formations by redistributing filtration flows, reducing or stabilizing water cut, reducing the volume of produced water, obtaining additional oil production.

Results: This article presents the results of laboratory studies on the selection of optimal flow diverter chemical compositions for the conditions of the Alibekmola oil field.

Conclusion: Conducted laboratory studies prove the applicability and effectiveness of flow diverter compositions for the conditions of carbonate fractured reservoirs.

Authors: Bidzhieva Salimat Kh. , Nurseitov Nauruzbek K. , Kalmukhanova Tilektes B. , Utepov Maksat S.
Published: January 2024

Rationale: Since 2018, at the Uzen oilfield, in order to study and control the microbiological contamination with sulfate-reducing bacteria (hereinafter referred to as SRB) of oilfield environment, full-scale bactericidal treatment and monitoring of the effectiveness of reagent use have been carried out. At the equipped control points, water samples are taken for the content of SRB cells before and after injection of the bactericide.
Target: Reduce the intensity of sulfidogenesis at the oilfield and, as a consequence, the concentration of hydrogen sulfide in the associated gas.
Materials and methods: Since the applied technology of injecting the bactericide in shock dosages did not allow achieving a stable reduction in the concentration of hydrogen sulfide, it was replaced by the technology of constantly injecting the bactericide into seawater at a dosage of 40 mg/l in an experimental mode. This technology showed low efficiency, hydrogen sulfide (H2S) concentrations varied between 352–379 ppm, and the monthly consumption of the reagent increased by 40%. Based on the obtained data on ineffectiveness, the constant injection of bactericide at MPS-4 was stopped and a new technology for injection of bactericide was proposed, aimed at suppressing not only planktonic, but also adherent forms of SRB.
Results: Results. Injection of the bactericide using the new technology showed significant efficiency, which was assessed by reducing the concentration of hydrogen sulfide in the associated gas by an average of 45% across the oilfield.
Conclusion: The proposed new technology for injecting a bactericide made it possible to effectively suppress the activity of sulfidogenic microorganisms and reduce the level of biogenic hydrogen sulfide in the oilfield.

Published: January 2024

The problem of treatment and neutralization of wastewater from chemical, petrochemical and oil refining industries is associated with the removing from them of suspended solid and plastic particles of pollution of various chemical natures, oil and petroleum products, heavy metals, surfactants, acids, alkalis, phenols and other harmful substances. To effectively treat water, various filters are used, which differ in parameters and characteristics. The purpose of this work is to determine the possibility of replacing cartridge filters used at PetroKazakhstan Oil Products LLP with easily regenerable bag filters. In the course of the research, it was found that the use of cartridge and bag filters contributes to more effective water treatment, in particular, from suspended sub- stances. When comparing them, we can say that the latter is advantageous in that it does not need to be changed when clogged, like a cartridge filter, but simply rinsed and used again in the technological chain. The bag element is quite simply washed in water, but if it is heavily clogged, it can be washed either in a solution of citric acid (20 g/l) or in an alkali solution (10 g/l).
An integrated methodological approach to substantiating the properties of high-viscosity oils using the example of the Karazhanbas oil field
Authors: Uteev Rakhim  N. , Kunzharikova Klara M. , Bisikenova Laura M. , Bektas Gaukhar Zh.
Published: January 2024

Rationale: A characteristic feature of the modern stage of oil field development is the increase in the share of hard-to-recover oils, which mainly include heavy, highly viscous oils. This is due to changes in the structure of oil, an increase in the water cut of produced oil, geological and geophysical characteristics and conditions of oil occurrence that are unfavorable for extraction. The reserves of such oil significantly exceed the reserves of light and low-viscosity oil and, according to experts, they amount to at least 1 trillion tons. In industrialized countries they are considered not so much as a reserve for oil production, but as the main basis for its development in the coming years. The peculiarity of heavy oil is explained by its composition and PVT properties, which have a fairly serious impact on production.

Target: Application of an integrated approach to substantiating the properties of high-viscosity oil and tools for mathematical modeling of the phase state of fluids in order to increase the reliability of reserve calculations and the efficiency of the oil field development.

Analysis of Physical Readiness for Take-Over in Automated Driving – Approach to Classify Non-Driving Related Activities According to Their Level of Complexity
Authors: Schäffer Miriam , Unselt Felix , Remlinger Wolfram
Published: January 2024

Take-overs are becoming part of the use of automated driving functions, since these functions will be limited to certain Operating Driving Domains at first. As the OEM must guarantee safe driving at all times, safe take-overs of the driver are also part of these driving functions. During automated driving in SAE Level 4 more postures and interior adjustments will be possible. This will make the evaluation and prediction of the take-over procedure more complex. In addition to the cognitive transition, the physical adaptation of the driver and the interior back to a drivable state must also be taken into account. In this work, three factors were identified that characterize non-driving related activities in physical terms: whether an item is used, whether the interior is adjusted and whether seat, steering wheel or pedals are adjusted. On this basis, four complexity levels were derived. By assigning an NDRA to a complexity level, the driver's effort for physical adaptation to the driving task and capability to take over can be derived.
Olfactory Profile: Enhancing the Satisfaction and Pleasure of Ride-Hailing Experiences
Authors: Liu Yang , Jie J Qiu
Published: January 2024

As ride-hailing services become a major mode of transportation for people's daily commutes, the quality of air inside the vehicle has always been a significant factor affecting the riding experience. Based on this, we have designed the “Olfactory Profile” system. This system enhances the comfort and enjoyment of ride-hailing passengers by providing a personalized olfactory environment throughout the entire ride and handling typical scents in various scenarios. The main functions include: First, creating a comfortable environment before getting into the car by releasing customized scents; Second, adjusting the emotional atmosphere during the ride through scenario customization. The specific method employed is the User-Centered Design (UCD) research approach. It involves uncovering user needs, transforming these needs into concrete design plans, and conducting experimental simulations with the developed prototypes. The evaluation of the prototypes is done through a combination of subjective interviews and objective physiological metrics analysis. Experimental results have demonstrated the usability and user-friendliness of the Olfactory Profile in enhancing the ride experience. The Olfactory Profile can be applied in future ride-hailing services to continuously improve the passengers' riding experience.
Cognitive User Modeling for Adaptivity in Serious Games
Authors: Streicher Alexander , Bauer Kolja
Published: January 2024

Accurate user models that capture information such as needs and knowledge levels are a central part of adaptive e-learning systems, which is all the more important in a post-pandemic world with more individualized learning. In this article, we report on the application of a Bayesian cognitive state modeling approach to adaptive educational serious games. Adaptivity needs information on the users as control variables, e.g., high or low cognitive load. Typically, this information is encoded in user models. One approach to building user models is to use tools from cognitive sciences such as Bayesian cognitive state modeling. However, cognitive modeling tools for adaptivity are sparse and can be difficult to implement. The main research question of this work is how to apply cognitive modeling tools to serious games to control adaptivity. The contribution of this article is the concept of how to implement cognitive modeling for adaptive serious games. Our approach makes use of standardized Experience API (xAPI) tracking data to facilitate applicability. We investigate how to compute quantitative measures of user performance to control adaptive responses. The implemented system has been evaluated in a user study with a serious game for image interpretation. The study results show a moderate correlation between self-assessed and computed variables.
