DETERMINATION OF THE EFFECTIVENESS OF WORK ON ARTIFICIAL REPRODUCTION OF COREGONUS PELED IN THE OB-IRTYSH BASIN
Authors: Matkovsky Andrey
Published: July 2021

The method of determining the effectiveness of artificial reproduction works is considered on the example of the Ob population of peled. The method is based on recording the moment when the population decline stops, and the subsequent increase in catches. Based on the average fishing return rate of 0.258% of the 1.5 g young, the catch from one million young is about 0.8 tons. It is established that the catch can increase to 2.6 tons per one million juveniles after the entry into the fishery of new offspring from the replenishment of the spawning herd. Taking into account the mass onset of sexual maturity of the peled at the 4th year of life, the greatest effect of artificial reproduction is observed at the 8th year. The equations for determining the period and level of restoration of the bioresource are given. It is noted that for the restoration of long-cycle fish species, the volume of young fish introduction should be at least 20 % of the receiving capacity. The rate of recovery of the bioresource depends on the following indicators: the volume of the introduction of juveniles, the intensity of fishing, the age of sexual maturity and the availability of conditions for natural reproduction.

Lagniappe: Comics Go to College
Authors: Lewis Megan
Published: July 2021

or many of us, reading comic books is a formative childhood experience.  Indeed, we can “read” comics pictorially before we can actually read. Comics are often the first reading material we select for ourselves and buy with our own money. The small-town newsstand where my brother and I bought Archie comics in the mid-’70s is etched into a corner of my brain: the ring of the bell as we opened the wooden door, the mingled smells of newsprint and tobacco, and the furtive glances towards the counter whilewe read as many comics as possible just out of the proprietor’s sight.  Since the 1930s, comics have been an integral part of the American scene.  They have both influenced our collective imagination and reflected the eras in which they were published. From movies (The Matrix) to literature (Michael Chabon’s The Amazing Adventures of Kavalier & Clay) to art (Roy Lichtenstein), the footprint of comics on the culture at large is a deep one.

Books in Tolerable Supply: College Libraries in North Carolina from 1795 to the Civil War
Authors: Valentine Patrick
Published: July 2021

The historical role of college libraries has seldom been investigated on a regional or state level in the United States, but such studies are valuable in explaining the cultural infrastructure of education and print culture. State and regional studies also set the context for future research on individual libraries and colleges as well as histories on a larger level. This work examines how college libraries developed in North Carolina from 1800 to 1860 and illustrates the growth and ambience of education and print culture during a formative period of the antebellum South.

Este ensayo explora las circunstancias específicas que inspiraron la composición de ‘El Contrabando de El Paso’, un corrido tequilero dentro de la tradición de la balada del lamento del prisionero y de los despedimientos. En estos textos, los personajes de corrido, encarcelados y a punto de morir, se despiden de sus seres queridos, se arrepienten de sus hechos y hacen reflexiones filosóficas acerca de la vida y de la muerte. ‘El Contrabando de El Paso’ es un corrido pionero y antecedente de lo que ahora se denominan narcocorrido y narcocultura.
Un andaluz responde a Washington Irving: las Tradiciones granadinas (1849) de José Soler de la Fuente
Authors: DE MORALES GALIANA JAVIER MUÑOZ
Published: July 2021

José Soler de la Fuente publicó en 1849 una compilación de cuentos titulada Tradiciones granadinas. La obra tenía por objeto recrear numerosas leyendas y tradiciones asociadas a la ciudad de Granada. Por el tema, la colección bien podría relacionarse con los Cuentos de la Alhambra (1832) de Washington Irving, si bien con una salvedad, y es que Soler de la Fuente se propone, en esta ocasión, llevar a cabo una respuesta a la obra de Washington Irving, que presentaba España como una nación oriental, influenciada por los musulmanes. La Granada que vemos en las Tradiciones granadinas, en cambio, será por completo cristiana, y las tropas islámicas aparecen únicamente retratadas como enemigos que vencer, cuya derrota llena de honor y gloria a las huestes cristianas, y supone un orgullo para la imaginada nación.
Investigation of the Origins of Comets as Revealed through Infrared High-resolution Spectroscopy I. Molecular Abundances
Authors: Lippi M. , Villanueva G. L. , Mumma M. J. , Faggi S.
Published: July 2021

We report and analyze updated molecular abundances in 20 comets obtained by employing modern data reduction procedures and molecular models. Using box and scatter plots, we examine how the different molecular species are distributed among the comet population, while by means of pie charts, we investigate the relative proportions of these molecular species in each comet. We compare these results with the orbital parameters of the selected comets to identify trends related to their dynamical history. With these analyses, we tentatively identify at least three chemical classes based mainly on relative abundances of CO, CH3OH, CH4, C2H6, HCN, and NH3. The combination of relative abundances and orbital parameters is then compared with recent chemical models of planetary system formation. This approach may help in investigating the origins and evolution of the material in cometary nuclei. Among other aspects, we underline the need to increase our sample size, especially for hypervolatiles (i.e., CH4 and CO) in Jupiter family comets.

The present-day envelope of gaseous planets is a relic of how these giant planets originated and evolved. Measuring their elemental composition therefore presents a powerful opportunity to answer long-standing questions regarding planet formation. Obtaining precise observational constraints on the elemental inventory of giant exoplanets has, however, remained challenging owing to the limited simultaneous wavelength coverage of current space-based instruments. Here, we present thermal emission observations of the nontransiting hot Jupiter τ Boo b using the new wide wavelength coverage (0.95–2.50 μm) and high spectral resolution (R = 70,000) CFHT/SPIRou spectrograph. By combining a total of 20 hr of SPIRou data obtained over five nights in a full atmospheric retrieval framework designed for high-resolution data, we constrain the abundances of all the major oxygen- and carbon-bearing molecules and recover a noninverted temperature structure using a new free-shape, nonparametric temperature–pressure profile retrieval approach. We find a volume mixing ratio of log(CO) = −

Combined, the inferred supersolar C/H, O/H, and C/O ratios on τ Boo b support a formation scenario beyond the water snowline in a disk enriched in CO owing to pebble drift.
Three-dimensional Reconstruction of Weak-lensing Mass Maps with a Sparsity Prior. I. Cluster Detection
Authors: Li Xiangchong , Yoshida Naoki , Oguri Masamune , Ikeda Shiro , Luo Wentao
Published: July 2021

We propose a novel method to reconstruct high-resolution three-dimensional mass maps using data from photometric weak-lensing surveys. We apply an adaptive LASSO algorithm to perform a sparsity-based reconstruction on the assumption that the underlying cosmic density field is represented by a sum of Navarro–Frenk–White halos. We generate realistic mock galaxy shear catalogs by considering the shear distortions from isolated halos for the configurations matched to the Subaru Hyper Suprime-Cam Survey with its photometric redshift estimates. We show that the adaptive method significantly reduces line-of-sight smearing that is caused by the correlation between the lensing kernels at different redshifts.

The estimated redshifts of the detected clusters are systematically lower than the true values by Δz ∼ 0.03 for halos at z ≤ 0.4, but the relative redshift bias is below 0.5% for clusters at 0.4 < z ≤ 0.85. The standard deviation of the redshift estimation is 0.092. Our method enables direct three-dimensional cluster detection with accurate redshift estimates.

Published: July 2021

We present a statistical analysis for the characteristics and spatial evolution of the interplanetary discontinuities (IDs) in the solar wind, from 0.13–0.9 au, by using the Parker Solar Probe measurements on Orbits 4 and 5. We collected 3948 IDs, including 2511 rotational discontinuities (RDs) and 557 tangential discontinuities (TDs), with the remnant unidentified. The statistical results show that (1) the ID occurrence rate decreases from 200 events per day at 0.13 au to 1 event per day at 0.9 au, following a spatial scaling of r
−2.00, (2) the RD to TD ratio decreases quickly with the heliocentric distance, from 8 at r < 0.3 au to 1 at r > 0.4 au, (3) the magnetic field tends to rotate across the IDs, 45° for TDs and 30° for RDs, in the pristine solar wind within 0.3 au, (4) a special subgroup of RDs exists within 0.3 au, characterized by small field rotation angles and parallel or antiparallel propagations to the background magnetic fields, (5) the TD thicknesses normalized by local ion inertial lengths (d

i
) show no clear spatial scaling and generally range from 5–35 d
i and the normalized RD thicknesses follow an r

Published: July 2021

This paper reports, for the first time on a statistical basis, on the key role played by the Alfvénic fluctuations in modulating the recovery phase of the geomagnetic storms, slowing down the restoration of the magnetosphere toward its pre-storm equilibrium state. Using interplanetary and geomagnetic measurements collected over more than one solar cycle, a high correlation between the durations of Alfvénic streams and concurrent recovery phases is found, pointing to a clear coupling between Alfvénic turbulence and magnetospheric ring current dynamics. By exploiting current solar wind models, these observations also provide space weather opportunities of predicting the total duration of any geomagnetic storm induced by any solar driver provided that it is followed by an Alfvénic stream, a crucial piece of information for ground technologies and infrastructures that are affected by time-integrated effects throughout the duration of the storm.
An Observational Signature of Sub-equipartition Magnetic Fields in the Spectra of Black Hole Binaries
Authors: Wallace John , Pe’er Asaf
Published: July 2021

A common assumption used in the study of accretion disks is that the magnetic energy density and the kinetic energy density should be in equipartition. This assumption relies on the faster growth rate of the magnetic field strength against the kinetic energy of the particles in the flow, for decreasing radius, combined with a dissipation mechanism that tends toward equipartition. In this paper, we examine this assumption by modeling the radio, millimeter, and optical spectra of several black hole binaries in their quiescent state. We use a standard two-component disk model, consisting of an inner geometrically thick and optically thin disk, emitting thermal synchrotron radiation, along with an outer, thin disk, which radiates as a multicolor blackbody. We find that at the low accretion rates typical of the quiescent state, the spectral shape is qualitatively reproduced using magnetic fields that are between 0.1% and 1% of the equipartition value, considerably smaller than previously thought. We discuss our findings in view of (1) the launching of jets in these objects, which is commonly believed to rely on the presence of a strong magnetic field in the central region of the disk, and (2) the role of magnetic dissipation in the structure of the inflow.
A Magnetic Disk-outflow Model for Changing Look Active Galactic Nuclei
Authors: Feng Junjie , Cao Xinwu , Li Jia-wen , Gu Wei-Min
Published: July 2021

The timescales of the variabilities in changing look (CL) active galactic nuclei (AGNs) are usually on the order of years to tens of years (some of them are even shorter than one year), which is much shorter than the viscous timescale of a standard thin accretion disk. This implies that the variabilities of CL AGNs cannot be reproduced by varying the mass accretion rate of the thin disk. In this work, we employ a magnetic accretion disk-outflow model to calculate the inflow time of the disk predominantly driven by magnetic outflows. In this model, most angular momentum of the gas in the disk is carried away by the outflows, and therefore its radial velocity can be substantially higher than that of a conventional viscous disk. Our calculations show that the inflow time of such a disk with outflows can be around several years to tens of years. The calculated spectra of the disk with outflows can fit the observed spectra of a CL AGN Mrk 1018 quite well both in the low and high states. The derived inflow time of such a disk with outflows is around 5 yr in the high state, while it becomes ∼20 yr in the low state, which is roughly consistent with the observations of the variabilities in Mrk 1018.
Deuterated Polycyclic Aromatic Hydrocarbons in the Interstellar Medium: The C–D Band Strengths of Multideuterated Species
Authors: Yang X. J. , Li Aigen , He C. Y. , Glaser R.
Published: July 2021

Observationally, the interstellar gas-phase abundance of deuterium (D) is considerably depleted and the missing D atoms are often postulated to have been locked up into carbonaceous solids and polycyclic aromatic hydrocarbon (PAH) molecules. An accurate knowledge of the fractional amount of D (relative to H) tied up in carbon dust and PAHs has important cosmological implications since D originated exclusively from the Big Bang and the present-day D abundance, after accounting for the astration it has experienced during Galactic evolution, provides essential clues to the primordial nucleosynthesis and the cosmological parameters. To quantitatively explore the extent to which PAHs could possibly accommodate the observed D depletion, we have previously quantum-chemically computed the infrared vibrational spectra of monodeuterated PAHs and derived the mean intrinsic band strengths of the 3.3 μm C–H stretch (A
3.3) and the 4.4 μm C–D stretch (A
4.4). Here we extend our previous work to multideuterated PAH species of different deuterations, sizes, and structures. We find that both the intrinsic band strengths A
3.3 and A
4.4 (on a per-unit-bond basis) and their ratios A
4.4/A
3.3 not only show little variation among PAHs of different deuterations, sizes, and structures, they are also closely similar to that of monodeuterated PAHs. Therefore, a PAH deuteration level (i.e., the fraction of peripheral atoms attached to C atoms in the form of D) of ∼2.4% previously estimated from the observed 4.4 to 3.3 μm band ratio based on the A
4.4/A
3.3 ratio of monodeuterated PAHs is robust.
The Augmentation Effect of N-Acetyl Cysteine Antioxidant on Superoxide Dismutase Levels in Schizophrenic Patients Treated with Risperidone
Authors: Camellia Vita , Khairunnisa Khairunnisa , Ichwan Muhammad , Husada Muhammad Surya , Effendy Elmeida , Rusdiana Rusdiana , Hendriaty Deasy
Published: July 2021

Background: Schizophrenia affects approximately 1% of the population and in Indonesia the prevalence is about 400.000 people or as many as 1.7 per 10000 individuals of the population. Schizophrenia is characterized by positive symptoms, negative symptoms and also cognitive, aggressive, and affective symptoms, where negative symptoms reflect loss of function.
One important factor that plays a role in the pathophysiology of schizophrenia is the excessive production of free radical substances and the failure of the anti-oxidant defense process.
The aim of this study is to see how levels of superoxide dismutase change after N-acetylcystein augmentation in schizophrenic patients treated with risperidone. This study is a pre-post experimental test design, where schizophrenic patients meet inclusion and exclusion criteria. At baseline, and after 8 weeks of N-acetyl cysteine administration, patients were assessed at each of the time points using PANSS, and SOD was measured in blood at both time points.      
The average negative PANSS score in the Risperidone + NAC baseline group was 29.93 (±1.83); in the Risperidone group was 29.83 (±1.19)  (p = 0.87). The average negative PANSS score at the end of week 8 was statistically significantly different (p = 0.001) in the Risperidone + NAC group (17.40 ±1.84) and in the Riseridone group (21.00±0.74). The average baseline SOD levels in the Risperidone + NAC group were 63.57 (±22.44), and in the Risperidone group was 85.79 (±101.05). SOD levels at week 8 in the Risperidone + NAC group were 71.72 (±31.20) and in the Risperidone group 128.27 (±117.67). ∆ SOD in the Risperidone + NAC group was 8.15 (19.54) and ∆ SOD in the Risperidone group was 42.48± (54.30).  p value of 0.028Research data shows that NAC augmentation can improve the negative symptoms of schizophrenia through reducing SOD levels in the blood.
Towards a Semantic Graph-based Recommender System. A Case Study of Cultural Heritage
Authors: Qassimi Sara , Abdelwahed El Hassan
Published: July 2021

Research on digital cultural heritage has raised the importance of providing visitors with relevant assistance before and during their visits. With the advent of the social web, the cultural heritage area is affected by the problem of information overload. Indeed, a large number of available resources have emerged coming from the social information systems (SocIS). Therefore, visitors are swamped with enormous choices in their visited cities. SocIS platforms use the features of collaborative tagging, named folksonomy, to commonly contribute to the management of the shared resources. However, collaborative tagging uses uncontrolled vocabulary which semanti- cally weakens the description of resources, consequently decreases their classification, clustering, thereby their recommendation. Therefore, the shared resources have to be pertinently described to ameliorate their recommendations. In this paper, we aim to enhance the cultural heritage visits by suggesting semantically related places that are most likely to interest a visitor. Our proposed approach represents a semantic graph-based recommender system of cultural heritage places through two steps; (1) constructing an emergent semantic description that semantically augments the place and (2) effectively modeling the emerging graphs representing the semantic relatedness of similar cultural heritage places and their related tags. The experimental evaluation shows relevant results attesting the efficiency of the proposed approach.
BSO-MV: An Optimized Multiview Clustering Approach for Items Recommendation in Social Networks
Authors: Berkani Lamia , Betit Lylia , Belarif Louiza
Published: July 2021

Clustering-based approaches have been demonstrated to be efficient and scalable to large-scale data sets. However, clustering-based recommender systems suffer from relatively low accuracy and coverage. To address these issues, we propose in this article an optimized multiview clustering approach for the recommendation of items in social networks. First, the selection of the initial medoids is optimized using the Bees Swarm optimization algorithm (BSO) in order to generate better partitions (i.e. refining the quality of medoids according to the objective function). Then, the multiview clustering (MV) is applied, where users are iteratively clustered from the views of both rating patterns and social information (i.e. friendships and trust). Finally, a framework is proposed for testing the different alternatives, namely: (1) the standard recommendation algorithms; (2) the clustering-based and the optimized clustering-based recommendation algorithms using BSO; and (3) the MV and the optimized MV (BSO-MV) algorithms. Experimental results conducted on two real-world datasets demonstrate the effectiveness of the proposed BSO-MV algorithm in terms of improving accuracy, as it outperforms the existing related approaches and baselines.
Luxury food tour: Perspectives and dilemmas on the "luxurification" of local culture in tourism product
Authors: Poljak Istenič Saša , Fakin Bajec Jasna
Published: July 2021

This paper focuses on the Kras/Carso Food Tour to present the challenges of developing a luxury tourism product. The tour's design followed the current strategy of the Slovenian Tourist Board, which defines specific criteria for a luxury experience. Contextualized by the experiential trends in tourism, the paper juxtaposes the bottom-up and top-down perspectives on luxury experiences. The authors argue that mediation by experts familiar with academic discourses and local culture is beneficial for the development of a successful tourism product. The study contributes to the debates on luxury tourism, which have neglected bottom-up perceptions in tourist discourse and overlooked the dilemmas people face when "luxurifying" their traditions and heritage practices.

Published: July 2021

Nowadays higher education that does not implement information and communication technologies (ICTs) is inconceivable; this places new demands on the level of qualification of teachers and the development of professional competencies in students. Therefore, the study of the readiness of universities for the introduction of ICTs is a relevant issue. The purpose of the research is to determine the predictors of the readiness of higher educational institutions for the introduction of ICTs. For this purpose, 218 students and 196 teachers of Moscow City University (Russia) were interviewed. The respondents were asked to fill in a specially designed questionnaire that included 40 key questions aimed at assessing the use of ICTs and their impact on student performance. The data analysis involved the following two steps: determining the level of ICT use in the educational process and comparing the indicators of the two groups of respondents - students and teachers. Lack of awareness of students on the introduction of new methods of learning in the educational institution was revealed in the course of the study. Although students and teachers note the steady development of the use of ICT in the educational process, they are not inclined to assess this area as the leading strategic goal of the institution. The primary task of ICT use in higher education is to train teachers and improve their skills. The use of ICT improves the quality of education and competitiveness of higher educational institutions, contributes to the development of professional competencies, but does not have a significant impact on the academic performance of students. Predictors of the use of ICTs in higher education are blended learning focused on the use of online technologies and independent work of students, virtual laboratories, as well as the development of open education and the MOOC system. The development of standardized quality control criteria will ensure the equality of diplomas in online and offline education.

Authors: Al-Yaseen Hussein
Published: July 2021

Abstract. Academic publishing appears to be the most important key of the academic functions (academic research, excellence in teaching and learning and community services). Selecting the right journal to publish research results is a challenge to academics. Yet, there is inadequate knowledge about a model specifically directed at the topic of the journal selection process with a mathematical certainty. The objectives of this research are: to identify the main factors that an author or researchers consider when selecting an academic journal for submitting a manuscript, and, to develop a mathematical algorithm of journal selection that provide the best journal choice with a mathematical certainty based on difficulty of each factor.
Quantitative research through questionnaires has been applied as an appropriate instrument base to address the researcher’s identification of the factors that should be considered when selecting a journal for submission a manuscript. Questionnaire developed and emailed to academics in 31 public and private universities in the developing countries.
Academics in the sample reported that the most important publication difficulty factors were publishing in reputable journals that are indexed and abstracted in well-known databases, and publishing in a journal that has an impact factor. However, the most least publication difficulty factors were found to be: number of issues per year of the journal and if the journal is an open access or with subscription. The proposed mathematical algorithm (equation) and a graphical model of journal’s publication difficulty factors were developed and tested on a sample of journals.

The learning model and environment are two major constraints on spoken English learning by Chinese learners. The maturity of computer-aided language learning brings a new opportunity to spoken English learners. Based on speech recognition and machine learning, this paper designs a spoken English teaching system, and determines the overall architecture and functional modules of the system according to the system’s functional demand. Specifically, MATLAB was adopted to realize speech recognition, and generate a speech recognition module. Combined with machine learning algorithm, a deep belief network (DBN)-support vector machine (SVM) model was proposed to classify and detect the errors in pronunciation; the module also scores the quality and corrects the errors in pronunciation. This model was extended to a speech evaluation module was created. Next, several experiments were carried out to test multiple attributes of the system, including the accuracy of pronunciation classification and error detection, recognition rates of different environments and vocabularies, and the real-timeliness of recognition. The results show that our system achieved good performance, realized the preset design goals, and satisfied the user demand. This research provides an important theoretical and practical reference to transforming English teaching method, and improving the spoken English of learners.

Authors: Chen Wei , Dai Fengwei
Published: July 2021

Based on context-input-process-product (CIPP) model, this paper proposed an evaluation system of the talent cultivation quality of modern apprenticeship in high vocational education schools, and applied the proposed system to evaluate the talent cultivation quality of modern apprenticeship in an example school H. The research findings of this study revealed that, on the one hand, it will greatly improve the quality of cultivated talents if the talent cultivation objectives are kept in line with the requirements of employer companies, the apprenticeship system is built according to the law of student growth and development, and there’re good apprenticeship project resources, support and management; on the other hand, it will have an adverse impact on the effect of apprenticeship projects if students’ employment willingness has not been fully motivated, or the implementation environment is poor for the apprenticeship, or the tutors in enterprises change frequently. Based on these findings, this paper proposed a few countermeasures for improving the talent cultivation quality of modern apprenticeship, that is: fully consider students’ appeals and boost their desire for employment; forge a team of enterprise tutors capable of and good at teaching; improve the quality of apprenticeship projects for junior year students; deepen the integration between industry and education and provide strong guarantee for both school education and enterprise training.

This article presents research and development on innovative photoactive admixtures for concrete and cement-based plasters for the finishing of concrete surfaces finished this year. The goal of the development was to provide the resulting surfaces of these newly developed materials with a self-cleaning ability stemming from photocatalytic reaction during exposure to UV radiation. The specific function of all these products is based on the photocatalytic oxidative mineralization of all organic structures present on the surface, i.e., their gradual transformation into the final simple inorganic compounds, which are carbon dioxide, water and the corresponding mineral acids. This research and development was carried out as part of a project supported by the Czech Ministry of Industry and Trade, in the TRIO programme; and in cooperation of BETOSAN s.r.o., the Technical University of Liberec, the Institute of Inorganic Chemistry of the Czech Academy of Sciences and the J. Heyrovsky Institute of Physical Chemistry of the Czech Academy of Sciences. The first type of developed material is a photocatalytically active admixture in powder form, allowing the preparation of concrete surfaces with photocatalytic properties. The second type of developed material is a photocatalytically active cement-based plaster, intended primarily for application to a concrete substrate. Two final versions of both materials were developed. In the case of the plaster this means preparation of two colour variants, specifically white and grey. For the powder concrete admixture two types with different application procedures were developed. This means one version of admixture mixed throughout the entire volume of the concrete and second variant applied only in the surface layer of the concrete. We anticipate mainly exterior applications on the self-cleaning outer shell of buildings, as well as treatment of the surface layer of various structures such as bridges, noise barriers, traffic barriers and tunnels. The developed materials can also be used in interiors under specific conditions, with anticipated uses in the health care and food processing industries.
Study of the Underground Placement of a Reinforced Concrete Containment Building

Published: July 2021

Nowadays, the safety of nuclear power plants is of increasing interest and importance. The main reasons for increased safety concerns are the recent major nuclear accident in Fukushima in 2011 and the overall tendency of environment protection. One of the possible ways of increasing the safety of nuclear power plants is the underground placement of all potentially dangerous systems under ground as the overlying soil or rock layer would act as a "earth" containment which would reduce the probability of ground level release following primary and secondary containment failure. Moreover, partial or total underground placement of nuclear power plant would reduce its visibility, and thus, public concerns would also be reduced. However, many design, operational, and economic disadvantages are linked with the underground placement of nuclear power plants. The aim of this paper is to provide state-of-the-art review of existing underground nuclear reactors, conceptual designs of underground nuclear reactors, and related literature, which can later be used for the design of a underground reinforced concrete containment building.
