Published: March 2023

Nowadays, lack of space in city center has forced the architects a propose a vertical construction to provide public facility, including the parking garage. Generally, this vertical parking garage has enclosed environment condition, which could be constructed under the building or in the middle of other buildings. This environment causes the parking garage will not have an adequate fresh air circulation or air change rate and gives a more risk due to the accumulation of air pollutants which is emitted from the cars inside. In this research, it observes a simple enclosed parking garage which normally can accommodate six cars. The air pollutant, particularly Carbon Monoxide (CO), from three gasoline cars is extracted by an exhaust fan in a proper location. Two location of exhaust fan are proposed to investigate better air circulation and better air pollutant extraction from the parking garage. The first option (Position of A) installs the exhaust fan near to the parking space units and the other installs the exhaust fan near to the pathway. Each option will follow two worst condition of simulations which are predicted will give a significant impact to Indoor Air Quality (IAQ). Each simulation has to extract the emission from three idle cars with same rate of air circulation of six air change per hour. The results show the influence of air flow pattern to the dispersion of air pollutant. An adequate air flow near to the emission source will cause the increase the maximum of air pollutant concentration. On the other hand, it can minimize the spread of air pollutant dispersion.
Free Convection Caputo-Fabrizio Casson Blood Flow in the Cylinder with Slip Velocity

Published: March 2023

Recently, fluid with fractional-order derivative model attracted many researchers to further study compared with the classical fluid mode since it is more precise and realistic. To imitate the applications of blood flow in narrow arteries, researchers focused on the fractional Casson fluid flow in the cylinder. However, most researchers solved the problems numerically and without considering the slip effect at the boundary. Thus, obtaining solutions analytically to the unsteady fractional Casson fluid flow in the slip cylinder with free convection is the goal of this study. The Caputo-Fabrizio fractional derivative approach is utilized to model this problem. By joining the approach of the Laplace transform and finite Hankel transform, the fractional governing equations are solved, and analytical solutions to the velocity and temperature profiles are gained. The fluid velocity rises as the slip velocity and Grashof number increase and it declines with the increment of the Casson parameter and Prandtl number. Increasing the fractional parameter will result in an increase in fluid velocity and temperature for a large time interval. The slip velocity effect influenced fluid flow, especially at the cylinder’s wall. These findings are beneficial to explore the more fractional-order derivative model and for studying the problems in biomedical engineering.
Throughflow and Gravity Modulation Effects on Thermal Convection in a Couple Stress Fluids Saturating a Porous Medium with an Internal Heat Source
Authors: Sravan Nayeka Gaikwad  , Preeti Bhushan
Published: March 2023

In this paper, the effect of throughflow and gravity modulation on thermal convection in a couple stress fluids saturating a porous medium with an internal heating source is investigated. A weakly nonlinear stability analysis is proposed to study the stationary mode of convection. The amplitude of gravity modulation is assumed to be very small and the disturbances are extended in terms of the power series of the amplitude of convection. Using a non-autonomous Ginzburg- Landau amplitude equation, heat transport is evaluated in terms of the Nusselt number. The finite-amplitude of convection has been derived in the third order. The amplitude and frequency of modulation have the effects of increasing or diminishing heat transport. The presence of a couple-stress parameter with internal heat source throughflow and modulation effects has been discussed. The effect of the internal heat source increases or decreases heat transfer in the system. For suitable ranges of Ω the throughflow and internal heating have both destabilizing and stabilizing effects. Finally flow patterns are presented in terms of streamlines and isotherms.

Surface-stabilized combustion burners or surface-radiant burners use perforated ceramic plates, ceramic foams, or metal fibers to stabilize a premixed flame. These burners are the most straightforward alternative to have both, the benefits of the reactant preheating technique and a great amount of heat transferred by radiation from the burner to the load. However, in its design, one of the greatest difficulties is to predict the flame stability limits; especially under operating conditions that lead to flashbacks and blowouts. This work presents a computational methodology based on the finite volume method with a two-dimensional domain to predict the flame curvature towards the unburned and burned gas that occurs before flashback and blowout, respectively. In the methodology, continuity, momentum, energy, and chemical species equations are solved to obtain the increase in the surface area of the flame. It was observed that this value can be used as a criterion to predict whether an operating condition is stable. When comparing the numerical results with experimental results reported in the literature, good predictions of the operating conditions that lead to flashbacks and blowouts are observed
Helminth and protozoan parasites of subterranean rodents (Chordata, Mammalia, Rodentia) of the world
Authors: Dursahinhan Altangerel T. , Kenkel Daniel A. , Gardner Scott L.
Published: March 2023

Published studies and ten new unpublished records included herein reveal that approximately 174 species of endoparasites (helminths and protozoans) are known from 65 of 163 species of rodents that occupy the subterranean ecotope globally. Of those, 94 endoparasite species were originally described from these rodents. A total of 282 host-parasite associations are summarized from four major zoogeographic regions including Ethiopian, Palearctic/Oriental, Nearctic, and Neotropical. Thirty-four parasite records from the literature have been identified to only the level of the genus. In this summary, ten new records have been added, and the most current taxonomic status of each parasite species is noted. Interestingly, there are no data on endoparasites from more than 68% of described subterranean rodents, which indicates that discovery and documentation are at an early stage and must continue.
Doing – Reflecting – Comprehending, Or: How We Found Resonance With Anarchist Pedagogy
Authors: Andrason Alexander , Gysman Vuyisa , Lange Hans-Christoph
Published: March 2023

The present auto-ethnographic article examines the compliance of an educational experiment implemented at Stellenbosch University (South Africa) with anarchist pedagogy. After describing this experiment, reflecting on it, and evaluating it within anarchist pedagogical theory, the authors
conclude the following: overall, the teaching and learning model implemented approximates the anarchist ideals to a considerable extent. However, this compliance is not uniform but rather instantiates a spectrum of possible enactments of anarchist pedagogy; the enactment of anarchist pedagogy
is patent from a macro/maximalist perspective while it is less significant from a micro/minimalist perspective. Since this compliance was not deliberate but emerged unwittingly through practice, the authors ponder whether anarchist pedagogy may be 'natural' or 'intuitive' for more lecturers
and students. Lastly, given their own experiences, the authors propose to consider the negative effects of anarchist struggle, such as suffering, alienation, and sacrifice, as inevitable from anarchist pedagogy and the essential elements of this pedagogical model.
An improved fixed-time stabilization problem of delayed coupled memristor-based neural networks with pinning control and indefinite derivative approach
Authors: Yang Chao , Wu Juntao , Qiao Zhengyang
Published: March 2023

In this brief, we propose a class of generalized memristor-based neural networks with nonlinear coupling. Based on the set-valued mapping theory, novel Lyapunov indefinite derivative and Memristor theory, the coupled memristor-based neural networks (CMNNs) can achieve fixed-time stabilization (FTS) by designing a proper pinning controller, which randomly controls a small number of neuron nodes. Different from the traditional Lyapunov method, this paper uses the implementation method of indefinite derivative to deal with the non-autonomous neural network system with nonlinear coupling topology between different neurons. The system can obtain stabilization in a fixed time and requires fewer conditions. Moreover, the fixed stable setting time estimation of the system is given through a few conditions, which can eliminate the dependence on the initial value. Finally, we give two numerical examples to verify the correctness of our results.

Authors: Gosar Anton
Published: March 2023

Podobe, besedila in valuta na poštnih znamkah predstavljajo ter promovirajo državo. Politična oziroma ideološka usmeritev države in kulturno izrazje naroda so tako v vizualni kot verbalni obliki odtis nekega časa. V prispevku smo preverjali izrazja (podobo in besedilo) na 841. poštnih znamkah, ki so bile izdane v dveh obdobjih, 1987–1991 v Jugoslaviji ter 1991–1995 v Sloveniji in na Hrvaškem. Priložnostne poštne znamke (535 znamk) smo razvrstili v pet tematskih skupin. Le-te v 315. primerih (59%) obravnavajo politično oziroma nacionalno pomembne vsebine. Pred razpadom Jugoslavije so poštne znamke poveličevale odpor proti okupatorju, socializem in uspešno mednarodno delovanje države. Prvi motivi na poštnih znamkah Slovenije in Hrvaške pa prikazujejo pomembne zgodovinske osebnosti in dogodke, predvsem iz obdobja narodnega prebujanja v 19. stoletju. //

Expressions of postage stamps in times of political and social transition on the territory of former Yugoslavia – part 1

Images, text and currency on postage stamps represent and promote the country. The political or ideological orientation and the cultural dominance of the nation are on stamps visual and verbal imprints of a certain time. In this paper, we’ve analysed expressions (image and text) on 851 postage stamps that were issued in two periods, 1987–1991 in Yugoslavia and 1991–1995 in Slovenia and Croatia. In a step further we’ve studied just »occasional postage stamps« (535 stamps) that have been classified into five thematic groups. We found out that in 315 cases the »occasional postage stamps« deal with political or national contents. Before the breakup of Yugoslavia, postage stamps glorified the resistance against the WW2 occupiers, socialism and the country’s successful international activities. The first images on postage stamps of Slovenia and Croatia depict important historical figures and events, mainly from the period of the national awakening in the 19th century.

Slovenian endonyms in bilingual geographical names in Italy, Austria and Hungary

This article deals with the use of bilingual geographical names in areas outside Slovenia where a native Slovenian minority lives. Because these names have not yet been standardized according to the recommendations of the United Nations, their use is very difficult. The standardization bodies of Slovenia’s neighboring countries are responsible for their standardization. Based on legal documents and official lists, the article compiles a list of bilingual names of settlements or their parts, which are recommended for use in Slovenian as well. There are almost three hundred such names in Italy, half that number in Austria, and seven in Hungary.
Numerical Study on the Effects of Coefficient of Friction to the Dynamic Sliding Contact between Bearing and Talar Components of Metal on Polymer Total Ankle Replacement Implants
Authors: Handoko  , Basuki Budi , Dharmastiti Rini
Published: March 2023

Coefficient of friction (cof) is an important variable when dealing with con-tact between mechanical parts. It depends on various tribological variables and the value can be determined only by experiments. Cof correlates with the wear of material and this is a severe problem in biomedical engineering. This research numerically studied the effects of cof between talar and bear-ing in the total ankle replacement (TAR) implants. The aim is to evaluate the contact situations affected by cof. The TAR models consist of cobalt chrome (CoCr) alloy and ultra high molecular weight polyethylene (UHMWPE) bio-materials. Five cof values of the dry, lubricated and frictionless TAR me-chanical contacts under ankle gait load were examined. The models use a fixed 1 mm element size for UHMWPE bearing component and four element sizes for the talar component, range from 1 mm to 0.4 mm. Results show that, 1) higher cof induces higher contact pressure, 2) contact stress is not af-fected by cof, 3) proper talar element size is 0.4 mm and 4) frictionless model can be used for the TAR contact mechanic computation. Frictionless model calculates equal contact stress and lower contact pressures with an error of 2.68 % compared to the smooth model.

SARS-Cov2 s, caused a high mortality in patients with some degree of immunosuppression, like those that receive a hematopoietic progenitor transplant. Since December 2020, several vaccines have been developed having been key in decreasing complications and mortality in this group of patients. Different articles have described the presence of thrombopenia related to the administration of vaccines, however, there are few data on the occurrence of neutropenia as a side effect after administration. We present several cases of neutropenia (defined as absolute neutrophil count (ANC) less than 2,000/mm3), after vaccination in hematopoietic progenitor transplant (HPT) recipients performed in our center during 2021.

Authors: Vargas-Hernández Diego A , Uscategui-Ruiz Adriana Catalina , Prada-Rueda Andrés Jesus , Romero-Sánchez Consuelo
Published: March 2023

Introduction: Sickle cell trait (SCT) is an autosomal recessive blood disorder in which patients are heterozygous carriers for hemoglobin S (HbAS) and are usually asymptomatic. We performed a descriptive analysis of clinical manifestations and outcomes associated with SCT.

Methods: This was a descriptive, cross-sectional study that included patients with SCT from 2014 to 2020 at Hospital Militar Central, the reference center of the Military forces in Bogota, Colombia.

Results: Of 647 hemoglobin electrophoresis analyzed, we identified 51 patients with SCT, including 43 males (84.3%) and eight females (15.7%), with a median age of 22 years (IQR 15–36 years). Of these, 28 (54.8%) were Afro-Colombian, and 23 (45.1%) were Colombian mestizos. Twenty-four patients (47.1%) were asymptomatic, and Twenty-seven patients (52.9%) were symptomatic (systemic complications); splenic complications were the most important (85.2%), p=0.0005, and there was a wide spectrum of splenic complications. We found significant elevations in leukocytes, bilirubin, LDH, and CRP. Eighteen patients (66.7%) received medical management, five patients (18.5%) required splenectomy, and only 5.9% of patients were sent for genetic counseling.

Conclusions: Splenic complications were the most relevant in symptomatic patients. Most patients received medical treatment, and 18.5% of patients required splenectomy. Our results reflect the absence of redirection of these patients to genetic counseling.

Published: March 2023

Objective: To explore the feasibility and accuracy of liver iron deposition based on dual-energy CT in thalassemia patients.

Materials and methods: 105 thalassemia patients were examined with dual-energy CT and MR liver scanning. Dual-energy CT was performed to measure CT values on 80kVp, 140kVp and virtual iron content (VIC) imaging, ΔH was figured out by the difference CT values between 80kVp and 140kVp. Using the liver iron concent (LIC) obtained by FerriScan as standard setting, the correlation between CT measurements and LIC was compared. Receiver operating characteristic (ROC) analysis was used to evaluate the diagnostic performance for dual-energy CT in liver iron quantification and stratification. 

Results: The correlation analysis between CT measurements and LIC showed that 80kVp, 140kVp, VIC and ΔH all had a high-positive correlation with LIC (P<0.001). The correlation analysis among different degree groups of VIC, ΔH and LIC showed that the normal, moderate, severe groups of VIC and ΔH had moderate or high positive correlations with that of LIC (P<0.01), but the mild group had no correlation (P>0.05). ROC analysis revealed that the corresponding optimal cutoff value of VIC were -2.8, 6.3,11.9 HU (corresponds to 3.2,7.0,15.0 mg/g dry weight) respectively, while the ΔH were 5.1, 8.4, 17.8HU, respectively. The area under the receiver operating characteristic curves (AUCs) for both VIC and ΔH increased with the increase of LIC thresholds.

Conclusion: Dual-energy CT can accurately evaluate liver iron deposition quantification and stratification, which contribute to predict the status of liver iron deposition of thalassemia patients.

Background and objectives: acute myeloid leukemia (AML) patients are at high risk of infections during post induction neutropenia. Recently, the role of antibacterial prophylaxis has been reconsidered due to concerns about the emergence of multi-resistant pathogens. Aim of the present study was to evaluate the impact of prophylaxis omission on the rate of induction death (primary endpoint), neutropenic fevers, bloodstream infections (BSIs), resistant pathogens BSIs and septic shocks (secondary endpoints). Methods:  we performed a retrospective single center study including 373 AML patients treated with intensive induction chemotherapy, divided in two groups according to levofloxacin prophylaxis given (group A, gA) or not (group B, gB). Results: neutropenic fever was observed in 91% of patients in gA and 97% in gB (OR 0.35, IC95% 0.08 – 1.52, p=0162).The rate of BSIs was 27% in gA compared to 34% in gB (OR 0.69, 0.38 – 1.25, p=0.222). Induction death rate was 5% in gA and 3% in gB (OR 1.50, 0.34 – 6.70, p=0.284). Fluoroquinolones (FQ) resistant pathogens were responsible for 59% of total BSIs in gA and 22% in gB (OR 5.07, 1.87 – 13.73, p=0.001); gram-negative BSIs due to multi-drug resistant organisms were 31% in gA and 36% in gB (OR 0.75, 0.15 – 3.70, p=0.727). Conclusions: levofloxacin prophylaxis omission was not associated with an increased risk of induction death. Cumulative incidence of neutropenic fever was higher in non-prophylaxis group, while no difference was observed for BSIs. In the prophylaxis group we observed a higher incidence of FQ resistant organisms.
A stroke rehabilitation training program for community-based primary health care, South Africa
Authors: Scheffler Elsje , Mash Robert
Published: March 2023

Background: With an increasing burden of stroke and a lack of access to rehabilitation services in rural South African settings, stroke survivors rely on untrained family caregivers for support and care. Community health workers (CHWs) support these families but have no stroke-specific training.Objectives: To describe the development of a contextually appropriate stroke training program for CHWs in the Cape Winelands District, South Africa.Method: Twenty-six health professionals and CHWs from the local primary healthcare services participated in action research over a 15-month period from September 2014 to December 2015. The groups participated in two parallel cooperative inquiry (CI) groups. The inquiry followed the cyclical steps of planning, action, observation and reflection. In this article, the planning step and how the CI groups used the first three steps of the analyse, design, develop, implement, evaluate (ADDIE) instructional design model are described.Results: The CHWs’ scope of practice, learning needs, competencies and characteristics, as well as the needs of the caregivers and stroke survivors, were identified in the analysis step. The program design consisted of 16 sessions to be delivered over 20 h. Program resources were developed with appropriate technology, language and instructional methodology.Conclusion: The program aims to equip CHWs to support family caregivers and stroke survivors in their homes as part of their generalist scope of practice. The implementation and initial evaluation will be described in a future article.Contribution: The study developed a unique training program for CHWs to support caregivers and stroke survivors in a resource-constrained, rural, middle-income country setting.
Impact of COVID-19 restrictions on South African air transport and tourism indicators
Authors: Vermooten Joachim
Published: March 2023

Background: Air travel restrictions to prevent the spread of coronavirus disease 2019 (COVID-19) impacted air travel to and from and within South Africa significantly. The duration of the pandemic was more protracted than initially expected as new variants of the pandemic (in ‘waves’) resulted in additional restrictions.Objectives: To determine the nature of COVID-19-related air travel restrictions, their impact on annual passenger demand, the number of flights operated (supply of services), the related average passenger loads carried as well as on tourism indicators of the direct contribution of travel and tourism, the total contribution to Gross Domestic Product (GDP) and employment.Method: The study identifies the number of passengers carried and flights operated and calculates the average passenger load per flight and trends. The impact on tourism indicators is based on the unit values of metrics published by the World Travel and Tourism Council for the 2019 calendar year, adapted for the reduction in passengers in the first and second years following the COVID-19 lockdown.Results: Significant decreases in the annual number of passengers carried, flights operated (in the three geographic areas), and their impact on tourism and employment indicators were identified.Conclusion: The decline in passengers exceeded the decrease in flights operated, which resulted in a decline in the average load of passengers carried per flight. The significance of COVID-19 restrictions on tourism indicators and employment was also calculated.Contribution: The study identifies the impact of COVID-19 air travel restrictions on both air transport and tourism indicators for South Africa.

Authors: Mutegi Tetu M. , Joshua Paul M. , Maina Jesse K.
Published: March 2023

Orientation: The manufacturing sector in Kenya has been experiencing employee safety and productivity issues despite adopting safety programmes and laws regulating employee safety. Employee safety attitudes significantly worsen workplace safety and productivity problems.Research purpose: The study determined the intervening effect of workplace safety attitudes on the relationship between workplace safety and employee productivity in manufacturing firms in Kenya.Motivation for the study: Manufacturing firms adopt new technologies that expose employees to new safety risks, while globalisation has led to a diverse workforce with diverse safety attitudes.Research approach/design and method: This study is grounded on the risk homeostasis theory; it adopted a cross-sectional survey research design guided by a positivist research philosophy. The target population comprised 853 manufacturing firms registered with the Kenya Association of Manufacturers. A sample of 124 firms distributed across the 14 sub-sectors in the manufacturing sector was obtained using a statistical formula to ensure all sectors were represented. Regression analysis was carried out in four steps to assess the intervening effect of workplace safety attitude on the relationship between workplace safety attitude and employee productivity.Main findings: The coefficients were significant in each step, therefore leading to the conclusion that employee safety attitude significantly intervened in the relationship between workplace safety and employee productivity.Practical/managerial implications: The study offers managerial insights into the situational position of workplace safety, employee safety attitudes and employee productivity.Contribution/value-add: The study provides epistemological insights on the impact of employee safety attitudes on workplace safety and employee productivity.
The politics of knowledge in South African universities: Students’ perspectives

Published: March 2023

Knowledge-making in South African universities is set up and framed in particular ways, with a Euro-centric bias. We argue that many of the contributions that African first year entering students could make to this process of knowledge-making are dis-abled, leading to alienation. In this article, we argue for a different perspective and approach to teaching and learning in the humanities. Former Extended Studies students from a South African university have worked collaboratively in a knowledge-making project, and using data generated from this, suggest different kinds of environments and strategies for more inclusive teaching and learning. Using an African feminist theoretical and methodological lens, we consider alternative ways of knowing, and recognition that supports powerful senses of belonging and agency, using examples from student experiences of an Extended Studies humanities programme. We contrast this with how humanities programmes are experienced by some first-year students at the university, sometimes with tragic consequences. Finally, we recommend pedagogic, curricula and extra-curricular changes that can be made, to realise the possibilities of decolonised knowledge-making that is more relevant and inclusive. The authors believe that the ideas around decolonising knowledge that are explored here are more broadly applicable and necessary.Contribution: The article contributes to the conversation on decolonising the humanities curriculum, by including students’ experiences, concerns, and suggestions.
Evangelism as an invitation to missional discipleship in the kingdom of God
Authors: Coetzee Frederik R. , Nel Malan , Knoetze Johannes J.
Published: March 2023

Evangelism, for various reasons, is once again back on the agenda of the church and theology. As a result of negative experiences and practices of evangelism in the past, it is now necessary to rediscover evangelism in a post-Christendom context to enable the theological recovery of evangelism. This new understanding of evangelism can then contribute to the recovery of authentic practices in spreading the good news. To achieve this, evangelism must be rediscovered as essential to mission (participation in the missio Dei). Further to this, evangelism is rediscovered as an invitation to missional discipleship in the coming of the kingdom of God (missional discipleship as participation in the coming of the kingdom). This research was based on the starting point that evangelism takes place through an integrated missional congregation as the evangelist. This implies that evangelism is not an additional extra practice by a few members but an integral part of congregational ministry. Evangelism is then understood and integrated holistically as martyria by the entire faith community. The gospel of the kingdom is then embodied in their faithful presence (being), loving service (deeds) and words of hope at appropriate times (speaking). This holistic approach will free evangelism from reductionisms and dichotomies that have added to the fact that evangelism has fallen out of favour. These practices of evangelism are determined by the theology (content) and serviceable style of Jesus and contextually discerned in faith as participating in God’s mission. The empirical research was based on 49 questionnaires received from 43 Dutch Reformed (DR) congregations from the Northern Synods and 6 other churches. The qualitative research comprised structured interviews with 10 pastors from participating DR congregations. Simple random sampling was used to select the participants of the study.Intradisciplinary and/or interdisciplinary implications: This research was conducted from the perspectives of practical theology and missiology. However, it also leaned into systematic theology (dogmatics) about missional ecclesiology and the identity of the church. The understanding of the integrated missional congregation (faith community) made use of systems theory, which is an interdisciplinary approach. The ethics of the practices of evangelism have points of contact with ethics.
God-talk and the question of being human
Authors: Bentley Wessel
Published: March 2023

The doctrine of the Trinity has, for centuries, dominated God-talk and the view of humanity within the framework of sin and salvation. This article investigated how God-talk, specifically the doctrine of the Trinity in Christian theology, speaks about both the nature of the Godhead and who we are as human beings. The article followed the outlines of our understanding of God’s transcendence, immanence and presence in experienced reality. It then proposed a new metaphor to describe the Trinity and how this affects the human quest for identity in a complex universe.Intradisciplinary and/or interdisciplinary implications: This article investigated the question of being human, using the Christian doctrine of the Trinity as a backdrop. This discussion entailed theology, anthropology and the dialogue between science and religion. The implication of this article is a more integrated perspective on the Trinity and anthropology in the science and religion discourse.

Authors: Mohammad Yaser , Awadh Salih
Published: March 2023

The research aims to study Sabkha mineralogy to determine the mineral types, the nature of the precipitation, and the patterns of salt crystallization. Two Sabkhas in Abu Ghraib, west of Baghdad, were studied. It was found that the Sabkhas were formed in flat ponds from saturated solutions in a semi-arid to arid climate. Halite predominates, followed by anhydrite and gypsum as evaporite minerals. As for the minerals of the Sabkha soil, it consisted of feldspar, calcite, quartz, and dolomite, in addition to the clay minerals represented by kaolinite, illite, and chlorite. Needle forms, hopper shapes, dendritic crystals, and polygon shapes are the main crystallization patterns dominantly found in the Sabkhas. All these types of crystallization occurre under normal temperatures.

Economic rare earth element bearing-heavy mineral accommodation in alluvial deposits (stream sediments) is a well-known process caused by varying rates of weathering and transportation of heavy minerals and sediments, which is significant in geochemical exploration. In the present work, stream sediment samples from Wadi Lethi, Sharm El-Sheikh, were systematically collected. The collected stream sediments were investigated mineralogically and geochemically using collaborative techniques. The separated heavy fractions have been analyzed for trace elements and Rare Earth Element. Important heavy minerals identified are monazite, sphene, apatite, garnet, xenotime, magnetite, ilmenite, and hematite, with subordinate riebeckite, epidote, and chlorite. Geochemical analyses of the separated heavy minerals revealed an abnormal concentration of total Rare Earth Element that was more than eleven times higher than in the studied area's granitic rocks. The Rare Earth Elements trends of these minerals depict the enrichment of light rare earth elements and the depletion of heavy rare earth elements, as well as the typical negative Eu anomaly found in granitic magma.

The Horus field is considered one of the most important hydrocarbon producers within the Alamein basin, Western Desert of Egypt. This area was affected by different tectonic movements throughout geological history. The re-evaluation and characterization of the Horus area, especially its main reservoirs of Lower Bahariya, middle Bahariya, upper Bahariya, and AR/G Dolomite units, because of its low production of oil tend (only 1100 BBD). Despite this, the Alamein basin is large and very rich in hydrocarbon. This study depends on the interpretation of thirty 2D seismic lines in addition to open-hole logs in the form of Resistivity, SP, GR, Density, Neutron, and Sonic logs for the five studied wells in order to delineate the subsurface structure and reservoir petrophysical characteristics of the Horus field. The data is tried to the formation tops and seismic lines by using synthetic seismograms. The main surfaces were mapped to proceed with the further static modeling. The work flow of the 3D geological modeling in the Horus area for characterization of the Bahariya Formation and AR/G Dolomite Unit. The processes that were carried out during the construction of the geological structure in the study area respectively, fault modeling, pillar gridding, skeleton grid, horizon modeling, zonation, and layering, and then distributed the facies and petrophysical parameters (Vsh, Sw and Φe) in this model. The main objective of this study is to delineate the seismic phenomena for structural, petrophysical, and facies modelling of the Bahariya Formation (Lower, Middle, and Upper) and AR/G Dolomite unit. The depth structure contour map on top of the Bahariya formation and the AR/G Dolomite unit indicated that the Horus area affected by NW-SE and WNW-ESE faults related to the lower Cretaceous. The study discussed the possibility of new structural traps that benefit in increasing the production of the area. All the results were consistent and confirmed that the Bahariya Formation and AR/G Dolomite are excellent reservoirs. Integrating multidisciplinary methods of seismic interpretation, static modeling, property modeling and well log analysis to design 3D structural and property models, helped predict new exploratory promising areas and structural traps to increase in production and the reserves in the study area, also decreasing the uncertainty of hydrocarbon exploration.

Dynamics of an oscillating wave surge converter: an analysis on the influence of the bottom slope
Authors: Vargas Guilherme Fuhrmeister , Schettini Edith Beatriz Camaño , Scapin Bruno Alavarez
Published: March 2023

The Oscillating Wave Surge Converter represents a technology with great potential for generating electricity from ocean waves, promoting energy continuously throughout a day. Its development is on a pre-commercial scale and has been encouraging several companies and institutions to invest in the improvement and study of this conversion system. Simulations in Computational Fluid Dynamics are very important tools for the development of these converters, since they provide essential details for the analysis of the variables that influence the system. In this context, the present work uses the Large Eddy Simulation modeling to study the influence of the bottom slope on the device dynamics, which is performed using the OpenFOAM v.4.1 computational code and its extension OlaFlow. The model used in the analysis is two-dimensional and based on the Wall-Adapting Local Eddy-Viscosity methodology, while a structured mesh is applied. Through a detailed analysis, it was observed that the converter hydrodynamics is strongly influenced by the bottom slope, which is responsible for the intensification of the captured power in regions with slopes lower than 5º, and for the power decrease in cases where the slope exceeds 15º. Significant increases in slope can cause a decrease up to 28% in the converter excitation torque, significantly affecting its performance in electric power generation.

La Canonización de Francisco de Borja (1671). La imagen del santo a través de la palabra
Authors: Pizarro Llorente Hénar
Published: March 2023

El ascenso a los altares de Francisco de Borja fue un proceso que se concluyó un centenar de años después de su fallecimiento. Los motivos que propiciaron su extensión en el tiempo fueron diversos, pero la prolongación de la causa tuvo como consecuencia una cambiante adecuación de la imagen proyectada del candidato a la santidad. Los sermones publicados desde su beatificación hasta la proclamación como santo fueron una herramienta esencial en la trasformación perseguida. Los jesuitas fueron quienes principalmente se ocuparon en este cometido, si bien contaron con el apoyo de los miembros de las ramas de la familia Borja y de los monarcas hispanos para la consecución de la deseada canonización.
