Numerous scientific studies have been carried out on the predisposition of the Pro47Ser polymorphism of the TR53 gene to breast cancer in women living in most countries of the world. However, no studies have been conducted on the susceptibility of this Pro47Ser gene polymorphism to breast cancer in Uzbek women. In this article, genotyping of the Pro47Ser polymorphism of the TR53 gene was performed for the first time in 207 Uzbek women. According to the results of our study, the functionally dangerous T allele of the Pro47Ser polymorphism of the TR53 gene was statistically significantly higher than that in healthy donors in patients with breast cancer; (ch2 = 8.2; p = 0.004; OR = 11.2; 95% CI: 1.422-88.38; RR = 10.7; 95% CI: 1.382-82.82). The safe C allele, on the other hand, was more common in the control group than in the main group. The natural S / C genotype was found in the control group with a higher frequency than in the control group. However, the limit of the statistical difference reached a significant level: (ch2 = 8.4; p = 0.004; OR = 0.08; 95% CI: 0.01066-0.676; ch2 = 8.2; p = 0.004; RR = 0.1 ; 95% CI: 0.8489- 0.9723). The S / T genotype of this polymorphism significantly differs in the frequency of occurrence in the main and control groups. Relative risk according to statistical analysis: RR = 10.7; (95% CI: 1.395–82.07) and odds ratio: OR = 11.8; (95% CI: 1.479-93.77). It is known that the minor T allele and the S / T genotype of this polymorphism increase the risk of developing breast cancer by 10.7 times. It should be noted that the unique homozygous genotype of Pro47Ser polymorphism was not identified in patients and control groups studied by T / T. Thus, the T allele and the C / T genotype of the Pro47Ser polymorphism of the TR53 gene are important factors that increase the risk of breast cancer (r <0.05). The C allele and S / S genotype of this polymorphism are reliable protective markers against the development of this pathology. Therefore, we believe that the Pro47Ser polymorphism of the TR53 gene can be used as important genetic markers in determining the likelihood of developing breast cancer.

Published: May 2021

Because kappa number cannot accurately represent the lignin content in the pulp after alkaline extraction, lead to the excessive dosage of bleaching chemicals added and the pollutant content increases. In order to accurately determine the dosage of bleaching agent, reduce pollutant emissions, a prediction model of lignin content of pulp was established by analyzing the correlation between lignin content and alkaline extraction conditions in this paper. The results show that the established soft sensor model can accurately measure lignin content, it is helpful to determine the amount of bleaching agent more accurately, reduce pollutant generation after pulp bleaching.

Published: May 2021

Waste paper recycling is an important way to realize the environmental protection development of the papermaking industry. The quality of the pulp will affect the pulp sales of the secondary fiber paper mills. The waste paper pulp can be adjusted by controlling the pulping process working conditions, but the working conditions of the waste paper pulping process have too many parameters. And the parameters are coupled with each other, it is difficult to control. In order to find the best working conditions and improve the quality of the pulp, this study uses the association rules algorithm to optimize the parameters for the waste paper pulping process. These parameters are power of refiner, waste paper concentration of refiner, the volume of slurry that enters deinked process, deinking agent amount, deinking time, deinking temperature, bleaching agent amount, bleaching time, and bleaching temperature. The test results show that the qualified rate of the pulp produced under the improved working conditions is 92.56%, an increase of 6.93%, and the average electricity consumption per ton of pulp is reduced by 5.76 kWh/t. In addition to potential economic benefits, this method can reduce carbon emissions.
Morphometry and Temperature of Simple Craters in Mercury’s Northern Hemisphere: Implications for Stability of Water Ice
Authors: Susorney Hannah C. M. , Ernst Carolyn M. , Chabot Nancy L. , Deutsch Ariel N. , Barnouin Olivier S.
Published: May 2021

Multiple lines of evidence support the hypothesis that Mercury’s polar regions host deposits of water ice in permanently shadowed regions, often within the interiors of craters. Pre-MErcury, Surface, Space, ENvironment, GEochemisty, and Ranging (MESSENGER) thermal modeling of the temperature of idealized simple craters found that the interiors of these craters were too hot to host near-surface ice on geologic timescales unless within 2° of the poles. However, results from the Arecibo Observatory and the MESSENGER mission identified many small, <10 km diameter, simple craters that host radar-bright deposits located considerably farther than 2° from the pole. Here we investigate the location and morphometry of north polar craters with diameters of 5–10 km and find that the craters were, on average, 30% shallower than the idealized simple crater morphometry assumed in previous thermal studies. The craters that host radar-bright deposits have an asymmetric longitudinal distribution that cannot be fully explained by the thermal environment and may be related to the original water ice deposition. We also investigate the maximum and average temperatures of the shadowed regions in these craters and find that many of them possess temperatures that allow water ice to be stable under a thermally insulating layer on geologic timescales outside of 2° from the pole. Thus, while the presence of radar-bright deposits in 5–10 km craters is not necessarily a constraint on the stability of the deposits, it provides additional information on the distribution and deposition of the water ice.
Phylogeny and evolution of large body size in the rove beetle genus Phlaeopterus Motschulsky, 1853 (Coleoptera: Staphylinidae: Omaliinae: Anthophagini)
Authors: Sikes Derek S. , Mullen Logan J.
Published: May 2021

Abstract

The omaliine rove beetle genus Phlaeopterus Motschulsky, 1853 contains 22 species. The genus is distributed across northwestern North America and eastern Asia. These beetles occur primarily along the edges of alpine snowfields and streams, habitats that are particularly sensitive to the impacts of climate change. Two species have not been collected since 1979 and 1984, one of which, Phlaeopterus bakerensis Mullen and Campbell, 2018, is a contender for the largest-bodied species among the over 1,600 species of the subfamily Omaliinae. Here, we present the first phylogeny of the genus, using Bayesian and maximum likelihood analyses based on DNA sequences from the mitochondrial gene COI and morphological data. We tested previous taxonomic hypotheses and most were rejected by all three analyses. Phlaeopterus castaneus Casey, 1893 is non-monophyletic based on COI sequences and may have hybridized with P. loganensis Hatch, 1957. We found support for the monophyly of the genus Phlaeopterus. Our analyses suggest the common ancestor of the genus had small-bodied adults (maximum body size under 5 mm) with ocelli. Within this small-bodied radiation of species, ocelli were lost once and there were two separate evolutionary transitions to large-bodied adults. Although all the large-bodied species are snowfield-associated and only 25% of the small-bodied species are, we did not find statistical support for a relationship between large body size and use of snowfield habitats. These findings represent the first modern phylogenetic reconstruction of species-level relationships within the rove beetle subfamily Omaliinae using both morphological and molecular data.
Revealing two centuries of confusion: new insights on nomenclature and systematic position of Argyrogena fasciolata (Shaw, 1802) (auctt.), with description of a new species from India (Reptilia: Squamata: Colubridae)

Coluber fasciolatusShaw, 1802 (todayArgyrogena fasciolataauctt.) is the name used for a widespread terrestrial colubrid snake species inhabiting subtropical and tropical dry deciduous/thorn forests of South Asia from Pakistan to India, with unconfirmed records of distribution in Nepal, Bangladesh and Myanmar and a single doubtful record from the northern tip of Sri Lanka.

During the past 200 years,A. fasciolata(common name Banded racer) has been placed in different genera, i.e.TyriaFitzinger, 1826,ZamenisWagler, 1830,CoryphodonDuméril, Bibron and Duméril, 1854, andColuberLinnaeus, 1758 where it primarly remained until the mid 1960s and exceptionally until the year 2011. Three subsequently introduced names, viz.Coluber hebeDaudin, 1803,Coluber curvirostrisCantor, 1839, andArgyrogena rostrataWerner, 1924 were synonymized withC. fasciolatusshortly after its description.

Based on a combination of characters including body pattern, external morphology and osteological differences Wilson (1967) reviewed the taxonfasciolatusShaw and considered it as generically distinguishable, removed it from the then heterogeneous and undefined collective genusColuberand assigned it to the resurrected genusArgyrogenaWerner, 1924.

Shaw’s (1802) description ofC. fasciolatuswas based exclusively on the information of Russell’s “Nooni Paragoodoo” published in 1796 in his “Account of Indian Serpents, collected on the coast of Coromandel; […]”. Our analysis of the original data and the depicted type specimen in Russell (1796) revealed that the namefasciolatawas initially established for a species distinct from that currently known as the “Banded racer”, and that Russell’s data have been used simultaneously but unwittingly, for more than 150 years, as original source for two valid species from two different genera.

Specimens of Banded racer found in the southeastern part of peninsular India are morphologically and genetically distinct from populations of the rest of the distribution area. These populations from central and southern Tamil Nadu state represent a different species, consequently described as a new species herein. Furthermore, examination of specimens of the Banded racer from different populations across its entire range, including the type specimen of the genusArgyrogena(A. rostrataWerner), reveals a similarity in morphology with the genusPlatycepsBlyth, 1860. This was further supported by molecular data which demonstrates that the genusArgyrogenais nested withinPlatyceps.
La pensée des séries télévisées : une lecture perfectionniste de Homeland et du Bureau des légendes
Authors: Blistène Pauline
Published: May 2021

Partant de l’œuvre de Stanley Cavell, et de ses écrits, moins réputés, sur la télévision, cet article entend faire valoir l’importance des séries télévisées dites d’espionnage pour nos formes de vie démocratiques. Prenant appui sur deux productions récentes, l’une américaine (Homeland, Showtime, 2011-2019), l’autre française (Le Bureau des légendes, Canal+, 2015-en production), il s’agira de montrer comment ces séries permettent une éducation morale et politique d’un genre nouveau, au-delà du simple reflet des problématiques sécuritaires contemporaines. Le terme « éducation » doit ici s’entendre au sens perfectionniste : non comme l’inculcation de normes, ni comme l’explicitation des bonnes valeurs à suivre, mais comme permettant une transformation de l’individu et de la société par la création d’une culture partagée et partageable par tous. Bien plus que des divertissements, ces séries révèlent au public des questions généralement absentes de la conversation démocratique - le secret, la violence et la raison d’État - c’est-à-dire les principes illibéraux qui sous-tendent les régimes démocratiques. Par le visionnage, le commentaire et le partage de ces séries, elles permettent donc au téléspectateur-citoyen de se saisir d’une part cachée et non moins problématique du politique.
La plasticité de l’humain et de l’inhumain dans Westworld. Scepticisme, perfectionnisme et mise à l’épreuve réciproque
Authors: Scalco Diego
Published: May 2021

Dans la série Westworld, les visiteurs du parc d’attractions homonyme interagissent librement avec des humanoïdes enfermés dans des boucles comportementales qui s’inscrivent dans le récit de la conquête de l’Ouest. Tout change au moment où le logiciel des humanoïdes fait l’objet d’une amélioration secrète par l’un des concepteurs du parc. Plusieurs humanoïdes commencent à transgresser les limites de leurs boucles respectives, sur la base de souvenirs et d’affects qui persistent à travers ces boucles. Les visiteurs se trouvant confrontés à des comportements de plus en plus spontanés, la frontière entre l’humain et l’inhumain devient poreuse, ce qui révèle leur plasticité même. Dans l’espace clos du parc, le rapport à autrui se teinte alors de scepticisme au sens de Stanley Cavell. Pour montrer qu’il n’existe point de situation idéale dans la (re)connaissance de ce qui est humain, Cavell recourt à la fiction de l’automate tellement amélioré qu’il ferait oublier son artificialité, y compris dans la simulation de la douleur et de la peine, plaçant ainsi autrui devant le dilemme de l’intervention. Dans Westworld aussi, la conversion au scepticisme envers les autres suppose la transition d’une approche de l’être et du (re)connaître vers une approche pratique (avec toutes les contradictions sous-jacentes). Les différents acteurs se trouvent engagés, malgré eux et de manière conflictuelle, dans une transformation des attitudes réciproques ayant des traits communs avec le perfectionnisme cavellien. L’enjeu ne consiste plus à (re)connaître une conscience dont l’humanoïde devrait être dépourvu et qui marquerait l’ascension au sommet de la pyramide évolutive, mais à établir une relation avec une intentionnalité étrangère, à l’émergence analogue au chemin vers le centre d’un labyrinthe.
Les séries TV comme nouvelles théories critiques en contexte identitariste et ultraconservateur. American Crime, The Sinner, Sharp Objects, Unorthodox
Authors: Corcuff Philippe
Published: May 2021

Une théorie critique à visée émancipatrice peut trouver un poumon de régénération aujourd’hui dans les cultures ordinaires, et en particulier dans les séries TV, en puisant notamment dans les travaux de Stanley Cavell sur le cinéma. Certaines séries peuvent ainsi participer à la réinvention de théories critiques, dans le sillage de l’École de Francfort mais en en déplaçant certaines formulations au contact des sociologies compréhensives et pragmatistes actuelles. Cela suppose de passer par un dialogue transfrontalier entre le « jeu de langage » des séries TV et le « jeu de connaissance » de la théorie politique, en empruntant des concepts inspirés de Ludwig Wittgenstein. Quatre séries sont traitées successivement : les saisons 1 d’American Crime (2015) et de The Sinner (2017), Sharp Objects (2018) et Unorthodox (2020). Les apports critiques de ces séries dessinent des affinités avec une philosophie politique de l’ouverture de l’être tirée d’Emmanuel Levinas. Cet article explore, sous l’angle du « jeu de langage » des séries TV, des thèmes traités au moyen des outils de la théorie politique dans le livre La grande confusion. Comment l’extrême droite gagne la bataille des idées (2021).
Green IT and the right portfolio of sustainable projects
Authors: Oliveira Jairo Cardoso , Rabechini Jr Roque
Published: May 2021

Sustainable development in the information technology industry is known as Green IT. Considering the need to generate consistent and sustainable IT projects, this paper presents a study on how Green IT criteria are used in the portfolio selection of information technology infrastructure projects. Method used was the multiple case studies, characterized by a qualitative evaluation. Object of this work was composed of sustainable companies whose shares are traded on the stock exchange, considering sustainability indexes. In addition to analysing the project portfolio management process, this work identified ten criteria that can be used to select information technology projects. We found that these criteria are not cost generators, but act on the tripod of cost reduction, maintenance or performance improvement and sustainability.
Applying Online Instructor Presence Amidst Changing Times
Authors: Rosser-Majors Michelle L. , Rebeor Sandra , McMahon Christine , Anderson Stephanie L.
Published: May 2021

Online learning can be challenging for both the students and instructors. Students can feel isolated or intimidated by the asynchronous environment, and instructors may find it difficult to connect with students as well as encourage active learning and critical thinking. Instructor presence (IP), as presented by the community of inquiry model (CoI), suggests that there are three areas of presence that must be applied cohesively to create an environment that is satisfying to students and the instructor: teaching, social, and cognitive. In this chapter, the authors report their findings of applied IP on student pass rates, drop rates, and satisfaction after exposing online instructors to IP training that provided immediate application examples. The findings suggested that when IP is applied effectively, student outcomes are significantly improved and are sustainable. This chapter will also share specific strategies, based on this model, that were utilized in the authors' research protocol.
Between Two Crises
Authors: O'Brien Kathryn G.
Published: May 2021

The purpose of this chapter was to critically examine the reconstruction of professional identity between two crises: The Great Recession of 2008 and the COVID-19 pandemic of 2020. Using a critical participatory action research self-study design, the author deconstructs the transition from for-profit behavioral health care business leadership to adjunct professor. Data sources include U.S. government job classification profiles, syllabi from courses taught, and the university's corresponding student surveys to answer the primary research question: How can teaching action research contribute to the reshaping of professional identity? Data analysis revealed that iterative cycles of reflection and action in teaching action research supported the development of identity as an academic across time. The knowledge, skills, and abilities required for a career in business supported, and also interfered with, career transition. Lastly, the author understood that the problem of practice stemmed from lack of recognition of her own privilege.
Investigating Inquiry-Based, Technology-Rich Global Education Through Action Research
Authors: Wafa Nada Zaki , Manfra Meghan McGlinn
Published: May 2021

As teachers increasingly face new challenges related to the COVID-19 pandemic and instructional adjustments related to digital and online learning, action research may provide a more effective approach for bringing about change. In this chapter, the authors provide an example of an innovative project in which a university-based researcher worked alongside an elementary school teacher to implement and assess a technology rich, global education program. The case followed the global education teacher from the initial stages of the curriculum implementation through teaching a complete unit. Using a collaborative inquiry model, the authors merged action research with qualitative case study methodology to develop a rich description of instruction. The aim was to understand teacher and student outcomes, while also exploring the benefit of engaging practitioners as co-researchers. The authors offer this project as a representative example of the myriad ways educators can leverage action research to develop innovative approaches to teaching and learning global education.
Ready to Engage?
Authors: Nikic Svetlana
Published: May 2021

This chapter examined teachers' responsiveness to targeted engagement interventions in their instructional practices in an urban middle school during virtual learning. These interventions were addressed through action research and consisted of professional development, coaching, and instructional feedback. Data collected in this eight-week study contained observational field notes, coaching plans, frequency charts, coaching questions, professional development constructs, surveys, artifacts, and interviews with six participant teachers. Findings show 1) positive responsiveness to teachers' engagement interventions, 2) increase in teachers' perceptions about instructional feedback and professional development, 3) coaching surfaced as most impactful intervention, 4) socio-emotional and behavioral engagement practices were least responsive to change, and 5) teachers' beliefs and growth mindset drove the need in practice change. Future recommendations consist of exploration into virtual practices.
Action Research Is Cyclical
Authors: Cunningham Tiffany
Published: May 2021

Due to the global pandemic, teachers have had to find and implement effective instructional strategies through distance learning. Current research surrounding “flipped learning” indicates this may be a viable option during distance learning. This study takes place in a 9th grade conceptual physics course taught entirely online. It focuses upon the cyclical nature of action research using four curricular units, concluding that the process of continual reflection, modifications, and improvements made as a result of data analysis contributes to student engagement and academic achievement. Finally, it brings to light the importance in guiding students to understand that teachers are always learning, modifying, and adapting, and that learning is a lifelong process. This transparency is crucial when developing rapport with students, especially during a global pandemic that we are all working through together.
Incorporating Spirituality in the Classroom
Authors: Hiatt Matthew A. , Reber Jeffrey S. , Wilkins Alan L. , Ferrell Jillian
Published: May 2021

This study tested the extent to which professors could be trained to help enhance students’ experiences of spirituality in their classes. Three areas of focus that may be important to incorporating spirituality into the classroom were identified in the integration of faith and learning literature: 1) Professor Self-Disclosure, 2) Intellectual Connections, and 3) Interpersonal Connections. In a quasi-experimental design, two professors were trained to incorporate these focus areas into four experimental conditions. A sample of 203 student participants attended different teaching conditions and rated their perception of the teaching quality. Statistical tests revealed that professor ratings on General Teaching Skills and Spirituality greatly improved after training; however, ratings also depended on the professor. Results indicated that applying such a pedagogical training can be a useful tool in educating faculty to successfully incorporate spirituality in the classroom and improve student perceptions of their general teaching skills.

Published: May 2021

Exploring the biological process to enhance the engineering properties of soil have received enormous recognition in recent years. Enzymatic induced calcium carbonate precipitation (EICP) is one of the bio-inspired methods of utilizing free urease to precipitates calcite from urea and calcium ions for bettering the geotechnical properties of poor soils. In this research, the EICP technique was used to improve the volumetric shrinkage strain of compacted soil liner. In this work, the residual soil was treated with various concentrations of cementations ranging from 0.25 to 1.0 M, and the soil was subjected to Atterberg limit tests, compaction test using British standard light (BSL) and reduced British standard light (RBSL) and desiccation drying volumetric shrinkage strain test. The study's findings revealed a remarkable improvement in the liquid limit and plasticity index of the treated residual soils compared to natural soil. It was also found that the volumetric shrinkage strain of the treated soil reduces progressively from 5.24% of natural to 1.49% at 1.0 M cementation solution when the soils were prepared at 0% OMC and BSL compaction effort. Based on the consideration of permissible VSS of less than 4%, the best treatment was obtained at 1.0 M for both BSL and RBSL prepared samples. Similarly, the best compaction plane is found in the treated with 1.0 M cementation solution.

Dietary Consumption and Its Association with Dental Caries in Schoolchildren in Benghazi, Libya
Authors: Huew Rasmia , Musrati Ahmed
Published: May 2021

Introduction:

Dental caries is a common public health problem among schoolchildren. Diet can affect oral health via many ways. Several researches have established that dietary factors are directly related to dental caries.

Aims:

To investigate the prevalence of dental caries in a group of schoolchildren in Benghazi, Libya, and its possible association with gender and diet.

Methods:

A cross-sectional observational study design was used among public schoolchildren in Benghazi, Libya. A random sample of 12-year-old school children within randomly selected schools underwent dental examination and completed a questionnaire to provide dietary data. This questionnaire was based on the one previously used in the UK National Diet and Nutrition Survey (2000). Dental caries was assessed using the World Health Organization criteria. Associations between caries and dietary variables under study were investigated through processes of bivariate and multivariate analyses.

Results:

About 62% had experience of dental caries. A higher experience of caries was observed among girls than boys (Fisher's exact test; P < 0.05). Consumption frequency of sugared drinks and foods was higher in girls (P < 0.001).

Conclusions:

Over two-thirds of the subjects had dental caries. The high level of dental caries is a cause for concern. Interestingly, more caries was noticed in girls than in boys. Apparently, sugared drinks, which were consumed more by girls, were the main source of total dietary sugared consumption. The consumption of sugared drinks was high, and efforts are required to reduce it.
Molecular diagnosis of infectious parasites in the post-COVID-19 era
Authors: Parija Subhash Chandra , Poddar Abhijit
Published: May 2021

The endemicity of several parasitic diseases across the globe and recent evidence of distress among COVID-19 patients with preexisting parasitic infections requires strengthening One Health framework and advanced strategies for parasitic detection. Owing to the greater sensitivity and accuracy, molecular technologies such as conventional polymerase chain reaction (PCR), reverse transcription (RT)-PCR, nested PCR, loop-mediated isothermal amplification (LAMP), and xMAP technology have been extensively studied for parasitic diagnosis. Varieties of genes have been targeted for primer development where 18S rRNA, internal transcribed spacer regions, and mitochondrial DNAs coding for cytochrome, and other enzymes have been widely used. More recent, low-cost sequencing and advances in big data management have resulted in a slow but steady rise of next-generation sequencing-based approaches for parasite diagnosis. However, except for few parasites of global concerns such as Plasmodium and Entamoeba, most of the molecular tools and technologies are yet to witness bench to bedside and field translations. This review looks into some of the advancements in the molecular diagnosis of parasites that have potential relevance to clinical purposes and may pave the way toward disease management in an efficient and timely manner.

Identifying dyslexia among Malaysian citizens, especially children nowadays is a prominent issue. The usual practice of dyslexia screening tests in the Malaysian school system is by teacher's observation and intervention. However, this is usually time-consuming, less accurate and lacking additional supporting tools. Moreover, dyslexic children enrolling in a normal education system will encounter many problems for the teacher and the children themselves. A Malay language mobile-based application for a dyslexia screening test named Kiddo Disleksia has been developed to solve this issue. However, it has not been tested in terms of Quality of Experience (QoE) as well as usability. Therefore, this research aims to test the QoE level of Kiddo Disleksia and also to compare the traditional dyslexia screening test with Kiddo Disleksia in terms of usability. To test the QoE, several special education teachers are required to rate Kiddo Disleksia using Mean Opinion Score (MOS). Ten children were tested using Kiddo Disleksia and 80% of them recognized as dyslexic. This result also similar with the traditional paper-based screening test. Therefore, the Kiddo Disleksia application is considered reliable for dyslexia screening tests for children. For QoE, the results show that the mean values of MOS are 3.9 and above. Therefore, the quality of experience during dyslexia screening tests can be enhanced using Kiddo Disleksia.

This paper discusses an event detection approach based on audio, which proves to be effective when applied to the audio component of cricket television broadcaster’s video. In this approach, both crowed noise levels which is in the background and commentator voice which is in focus are considered correlated to key events in the time frame. Classifiers related to Hidden Markov Model (or HMM) are utilized as it is an efficient tool for modeling processes varying with time and broadly used in the area of speech recognition. This experiment done using cricket television broadcaster videos, was successful thus this method can be used for automatic indexing of audio (or video containing audio) for quick searching or segmentation.

The Tam Ky - Phuoc Son suture zone (TPSZ) is located in central Indochina and is referred to as a amalgamation site between the Truong Son and Kon Tum terranes during the early Paleozoic. The amphibolite and ultramafic rocks within the region were considered as a part of the Tam Ky - Phuoc Son ophiolitic complex. In this study, the authors present results of the U - Pb dating and trace element composition of the zircon grains derived from a granodioritic sample collected in the G18 gold mine in Quang Nam province in order to clarify the timing of magma emplacement and tectonic setting. The U - Pb dating data indicates that the granodioritic rocks formed at 447,4±2,9 Ma while the U/Yb ratio is ̴1 (average: 1.32) and the Sc/Yb ratio is ̴ 1.04, high Hf content (Average Hf: 10937 ppm) and low Yb content (Average Yb: 308 ppm). These geochemical values are comparable with the zircon, which is formed in the continental magmatic arc. Combination with the pre - existing data allowed us to confirm the existence of two contrast magma members in the North Kontum massif: The Middle Cambrian island arc complex and the Middle Ordovician continental complex.

Published: May 2021

Tunneling in urban areas is growing in response to the increased needs for efficient transportation. Many urban tunnels are constructed in soft ground at shallow depths. Metro tunnels are usually constructed as twin-parallel tunnels and their adjacent constructions may lead to surface deformation, affecting the surface environment and the safety of the tunnels. Shield tunnelling is a commonly used as construction technique because it is very effective in reducing ground deformations and thus damage to urban infrastructure. The paper presents a 3D simulation of shield tunneling machines via the finite element code Abaqus and analysis model of ground surface settlements induced by a construction of twin-parallel tunnels. The results show that ground surface settlements induced by a construction of the left tunnel causes surface settlements of about 22÷24 mm and after the construction of both tunnels, it will cause ground subsidence has the greatest value of 33÷35 mm.

If the raw error appears in set of measuring data, it affects significantly on adjustment results and displacement values of monitoring points, thus conclusion about displacement of works is incorrect. The method of robust estimation by posterior variance for detecting the raw error bases on principle of choosing weight of robust estimation, this is the other type that belong to the least square statistical estimation, which is used to process the measuring data with raw error when they were given into random model of the adjustment problem. Through processing data of Son La hydroelectricity construction network, the obtained result proved that the method good efficiency, it not only finds the measuring value that contains the raw error, but also determines the value of the raw error nearly accurately, moreover, it is able to detect many raw error in the set of data.

Published: May 2021

The groundwater vulnerability to pollution in parts of Orlu metropolis, Southeastern Nigeria, was assessed on the basis for proposing an appropriate strategy for protecting the groundwater resources. The vulnerability assessment was accomplished using the LeGrand and GOD models. The model techniques generally involve parameter rating and point count systems, based on evaluation of various hydrogeological parameters in relation to their capacity to influence the flow of contaminants in the groundwater system. Borehole information of five locations was collected within the area. The result show that the unsaturated zone material of these sub areas is composed of sandy-clay facies with low effective hydraulic conductivity (k3) and relatively high sorption properties. The characteristics of the overburden materials indicate that contaminants would not migrate down to the water table with ease, especially areas where the water table is deep. The area generally has extremely low vulnerability and has considerable depth to water table which enhances contaminant attenuation and retardation. Also, the high sorption properties of the overburden materials tend to inhibit advective flow of contaminants down the water table. Policies should be instituted to facilitate the closing of pollution sources in the area of high vulnerability such as open disposal pits, leaking petrol stations, effluent discharge from industries, and use of pit latrines, and to locate future disposal site in areas of lower vulnerability.
Russian Law Enforcement Intelligence-Gathering Legislation: Problems and Ways to Address Them, Taking into Account the Experience of Some CIS Countries
Authors: AGARKOV ALEKSEI V.
Published: May 2021

Introduction: law enforcement practice and scientific research in the field of the theory of intelligence-gathering activities prove that current Russian intelligencegathering legislation contains quite a few legal gaps and contradictions. The article provides a scientific analysis of a number of problematic issues concerning legal regulation of intelligence-gathering activities conducted in the Russian Federation, with an emphasis on the functioning of operational units of the penal system of the Russian Federation. Aim:to work out proposals to improve national intelligence-gathering legislation by reviewingintelligence-gathering legislation of CIS countries, analyzing the works of scientists on the theory of intelligence-gathering activities and regulatory framework for the work of operational units. Methods: comparative legal method, theoretical methods of formal and dialectical logic, specific scientific methods: legal-dogmatic method, interpretation of legal norms. Results: the article considers the inconsistency between the purpose of intelligence-gathering activities enacted in law and both the law enforcement practice and its legally defined tasks, the absence of a number of significant tasks, as well as the grounds for conducting intelligence-gathering activities by operational units of the penal system, the lack of legal regulation of the content of intelligence-gathering activities and their procedure. To prove the existence of these shortcomings, we analyze the most common intelligence-gathering measures such as questioning and inquiries. Having studied intelligence-gathering laws of several CIS countries we found some norms regulating intelligence-gathering activities in the penitentiary system, the use of which, in our opinion, is possible in Russian context. Based on this, we make proposals to improve legal regulation of intelligence-gathering activities, in particular, by disclosing the concept of each intelligence-gathering activity in the norms of intelligence-gathering law. Conclusions: the article develops and substantiates proposals for improving Russia’sintelligence-gathering law and concludes that it is necessary to transform fundamentally the legislative regulation of intelligence-gathering activities in Russia by adopting the appropriate code. Keywords: intelligence-gathering activities; intelligence-gathering measures; shortcomings; problems; intelligence-gathering law; theory of intelligence-gathering activities; intelligence-gathering code.
