Compacting a material means applying pressure so that the material itself loses its internal pores. It improves the homogeneity of the material itself and increases its density. The pore structure of compacted clay is also an important factor that affects its mechanical properties, permeability and water absorption. In this study, MX-80 bentonite clay was first compacted into round cakes of different densities and then subjected to tomography image analysis technique using micro-computed tomography (micro-CT) at millimeter scale of accuracy for 1.0–2.0 g/cm3 compacted clay (thickness of 0.3 cm bentonite compacted clay). In this paper, we use the latest commercial specifically for scientific visualization, materials science, non-destructive testing, numerical simulation of chromatographic imaging and other functions of a powerful visualization of the image analyzing method.

Authors: Zhu Qiandong , Xie Xiaozhen
Published: February 2024

The development of digital and mobile technology has led to the emergence of digital scholarship, which is a challenge but also an opportunity for higher education institutions to improve their space and relevant services to support students’ success. The purpose of this study is to explore university students’ needs and expectations on digital scholarship spaces and relevant services in an academic library, as well as the differences in this based on gender, academic identity, and subject being studied. We conducted a survey at Shipai campus of Jinan University in Guangzhou to collect and analyze users’ needs and expectations. Among the digital scholarship service, the demand scores of the top three services are text recognition and full-text processing with 7.00, academic paper writing, submission, publication, and dissemination consulting services with 6.86, and digitization of printed documents with 6.72. Elsewhere, the demand score of the top three spaces are the online digital scholarship space with 6.57, the research project application and exchange space with 6.43, and the text analysis, data analysis, Big Data, and visualization service center with 6.27. With the improvement of academic identity, the demand for digital scholarship services is higher. Gender has led to differences in a small number of space needs, while the differences brought about by the subject being studied are more significant. This research contributes to the understanding of how the digital technology, the students’ spaces needs, and relevant management practice merge in academic libraries for students’ learning and research purposes. These have implications for universities to improve their libraries’ space services oriented to the diverse users’ digital scholarship needs in the current digital learning environment.
Harmonic quantum cascade laser terahertz frequency combs enabled by multilayer graphene top-cavity scatters
Authors: Justo Guerrero Manuel Alejandro , Arif Omer , Sorba Lucia , Vitiello Miriam Serena
Published: February 2024

Optical frequency comb synthesizers, operating in the harmonic regime, are metrological sources in which the emitted optical power is concentrated in a few modes, spaced by several multiples of the cavity free spectral range (FSR). This behavior reflects in a large correlation degree and, in principle, in an increased optical power per mode. In miniaturized quantum cascade lasers (QCLs), harmonic frequency combs (HFCs) are hence particularly attracting to explore quantum correlation effects between adjacent harmonic modes, enabled by the inherently large gain media third-order χ
(3) Kerr nonlinearity, even if controlled generation of stable HFCs of predefined order, is typically demanding in such electrically pumped sources. Here, we demonstrate stable 2nd order and 3rd order HFC emission in terahertz frequency QCLs by respectively patterning an individual or a couple of equally spaced distributed multilayer graphene absorbers on the top metallic waveguides.
Tensile and Impact Properties of Cast Stainless Steels at Cryogenic Temperatures
Authors: Hall E. R.
Published: February 2024

Tensile and notched-bar impact tests were performed on production heats of seven grades of cast chromium-nickel stainless steels at temperatures from 70 F to −430 F. No ductile-brittle transition was observed for any of the alloys including those having a small amount of delta ferrite dispersed in the microstructure. Retention of toughness at low temperature was dependent upon an austenitic structure and low interstitial (carbon + nitrogen) content. Markedly higher tensile strength at the lower temperatures was contingent upon the formation of martensitic ferrite in the Md−Ms temperature range. The presence of martensitic ferrite was indicated by stress-strain behavior, magnetic permeability, and microstructural features.

Published: February 2024

A marcha humana possui informações sobre o estado de saúde de um indivíduo, podendo indicar a presença de patologias. Assim, a implementação de um sistema de análise da marcha que seja preciso, não invasivo e de baixo custo, tem aplicação importante na realização de diagnósticos, no monitoramento, no tratamento e na reabilitação. Neste sentido, a análise da marcha corresponde ao processo que envolve desde a coleta de dados até a determinação de informações quantitativas capazes de descrever o padrão considerado como normalidade e os padrões associados às patologias. O diagnóstico precoce e preciso é fundamental para o desenvolvimento do plano de tratamento e para a avaliação das melhorias obtidas com a terapia adotada. Em um passado mais recente, sistemas baseados em sensores óticos que realizam o rastreamento de pontos do corpo humano sem marcadores têm sido empregados dentro do contexto de aplicação médica, por meio da extração de parâmetros espaço temporais da passada, do ângulo de articulação do joelho, dentre outros, a partir das informações coletadas pelo sensor Kinect, o qual pode ser utilizado para o rastreamento da dinâmica dos membros inferiores e superiores, os quais trazem informações sobre a marcha. Neste contexto, o objetivo do trabalho é aplicar um sistema para extrair parâmetros espaço temporais dos sinais de 20 marchas diferentes, e no fim realizar uma análise de padrão e anomalias entres eles. Com a câmera Kinect V2 e o software MatLab, se extraiu os ciclos de marcha de 20 indivíduos, foram feitas gravações de dois minutos em três velocidades diferentes: 1,5 Km/h, 2,0 Km/h e 3,0 Km/h. Para uma primeira análise, se utilizou algumas ferramentas de processamento de sinais, como a aplicação de filtros digitais e formalização das características físicas espaciais no tempo e na frequência. Com os dados devidamente processados, foi fixado limites superiores e inferiores de variação normal de cada parâmetro extraído, considerando o desvio padrão da população constituída na base, e se percebeu alguns indivíduos com padrões bem diferentes quando comparado com a população estudada. A partir disso, foi realizado uma modelagem não supervisionada a partir da análise de agrupamento k-means, advindo do campo da mineração dos dados. Análise que permitiu extrair a informação que a população pode ser dividida em 5 diferentes grupos. Cada grupo possui algumas características particulares com relação aos ângulos do calcanhar e do joelho com a coxa. Isso mostra uma potencial possibilidade de encontrar padrões que possam classificar anomalias, ou patologias, quando aplicado em populações maiores.

The success of the aquaculture sector relies on a consistent supply of healthy fish seeds. Rotifer has been identified as superior live food to artificial feed for nurturing fish larvae, the culture development of which largely depends on green microalgae. This study aimed to investigate the suitability of Chlorococcum sp. for enhancing the production of Brachionus calyciflorus. Two experiments were conducted to assess the effects of different food types and concentrations of Chlorococcum sp. on the growth of B. calyciflorus. In the first experiment, three food types were tested: live Chlorococcum sp. (1 x 105 cells/mL; T1), baker’s yeast (0.2 gm/L; T2), and a combination of live Chlorococcum sp. and baker’s yeast (0.5 x 105 cells/mL + 0.1 gm/L; T3). The highest population density and growth rate (r) of rotifers were observed in the T1 diet. In the second experiment, three concentrations of Chlorococcum sp. were tested: 0.5 x 106 cells/mL (T1), 1 x 106 cells/mL (T2), and 3 x 106 cells/mL (T3). Both the population density and growth rate of B. calyciflorus were found highest in the T3 diet. In conclusion, Chlorococcum sp. at a concentration of 3 x 106 cells/mL is suggested as the best food for the successful mass culture of the rotifer B. calyciflorus.

Authors: Scott Linda
Published: February 2024

The first South African case of the coronavirus disease (COVID-19) in March 2020 escalated to the national lockdown by the end of March 2020. This caused serious repercussions for learners, as there is a lack of infrastructure in South Africa to support online teaching and learning. The purpose of this study was to investigate the use of digital technologies during COVID-19 by teachers. A case study was used and data were collected using a desktop literature review and a semi-structured, open-ended, qualitative questionnaire. The questionnaire was administered to teachers at a secondary school in the Gauteng province, South Africa (SA) and Atlas.ti was used for data analysis. We conclude that online learning was affected by socio-economic problems, the high cost of data and the lack of devices and parental supervision. The recommendations include ways in which government could prepare for future crises that could arise, as well as promoting ongoing attention to digital technology use in teaching and learning to address the digital divide in South Africa. With this study we add to the body of knowledge regarding COVID-19 and the use of digital technologies in teaching and learning, which will assist the government and teachers in understanding the problems and solutions for the use of digital technology in teaching and learning.

The issue of discretion when seeking compensation for violation of labor law in connection with employee discrimination
Authors: Jeżak Bartosz
Published: February 2024

The purpose of this article is to present the issue of discretion in calculating the amount of compensation for discrimination suffered by an employee. In the article we will find information not only related to the provisions resulting from the Labor Code, but also related to the constitutive prohibition of discrimination, and regulations resulting from Poland’s membership in the European Union. The article presents aspects related to the provisions of the Civil Code in the event of a situation in which there would be no discriminatory criterion and in a situation where such a criterion occurs. The issue of discretion raises many controversies, in particular when a uniform line of jurisprudence has not been developed and the whole will be based on the experience of the judge, the Polish region and additional methods that the judge will use when adjudicating the amount of compensation.

One of the important tasks in geophysical studies of operating wells is the detection of behind the casing flows. The traditional complex of geophysical methods (thermometry, flow metering, composition methods, and others) does not always make it possible to detect the movement of fluid behind the well casing. To solve this problem, it is promising to use the method of active thermometry.Research technology using this method involves recording the temperature in the well during induction heating of a small section of metal casing. As a result of heat exchange between the heated section of the column and the liquid flow, a thermal disturbance is created in the annular flow channel. In the presence of behind the casing flow, heat will be carried away from the induction heating region in the direction of liquid movement and will be redistributed in the column above or below the heating interval. By recording the temperature of the casing during induction heating and after turning off the inductor, it is possible to establish the fact of cross-flow and quantify its flow rate.This paper studies the influence of the direction and flow rate of behind the casing flow on the unsteady temperature field in a metal casing during its local induction heating. The problem is solved numerically in the Ansys Fluent software package. The temperature field in the fluid in the wellbore is calculated taking into account free convection.The model temperature distributions obtained for different behind the casing flow configurations (direction, flow rate) can be used for quantitative interpretation, to determine the flow rate in the behind the casing flow channel by comparing actual and model temperature curves. To assess the intensity of behind-the-casing movement, time measurements at a “point” in the induction heating interval are also informative. The direction of flow is determined by the nature of the temperature distribution in depth above and below the induction heating section.

Published: February 2024

Study purpose. This study aimed to compare the effects of hypoxic exercise combined with crocodile blood supplementation on hematological and maximum oxygen consumption parameters in soccer players. 
Materials and methods. This study included 39 male soccer players aged 21.69 ± 1.98 years who were randomized to three groups. All groups performed the same training program, which comprised treadmill exercise at 70%–75% of maximum heart rate for 7 weeks with sessions of 30 min/day and 3 days per week. The first group was the control placebo group (CG, n = 13), the second group received one capsule per day (60 mg) of a freeze-dried crocodile blood supplement (SUP, n = 13), and the third group received the freeze-dried crocodile blood supplement and performed the training program under hypoxic conditions (H-SUP, n = 13, FiO2 = 16.3%). A hematological evaluation was conducted and maximal oxygen uptake (VO2max) was measured using the Bruce protocol treadmill test. 
Results. The H-SUP group demonstrated significantly higher erythropoietin (EPO) levels (14.40 ± 2.41 mIU/mL) compared to the SUP group (11.50 ± 2.08 mIU/mL) and CG (12.01 mIU/mL) after the intervention. From pre- to post-intervention, VO2max significantly increased in the H-SUP (Pre: 45.63 ± 4.75, Post: 49.33 ± 5.81) and SUP groups (Pre: 44.59 ± 4.75, Post: 47.30 ± 5.68) but not in the CG. 
Conclusions. This study reveals that a combination of freeze-dried crocodile blood supplementation and hypoxic exercise causes hematological alterations, particularly the activation of EPO secretion, and increases VO2max in soccer players.

Authors: Vautier Marine , Chardon Cecile , Galiegue Cyrielle , Domaizon Isabelle
Published: February 2024

The aim of this protocol is the digital droplet PCR (ddPCR) quantification of DNA target(s) using primer and probe sets. This protocol is optimised for the analysis of environmental DNA (eDNA) samples (water, sediment, biofilm and soil matrices) and then rare DNA targets. THe ddPCR can be performed using a QX600 or a QX200 droplet reader system, and this protocol begins after the DNA extraction step and ends with the droplet reading. The ddPCR for probes consists of the absolute quantification of samples using primers and fluorescent dye-labelled probes. The ddPCR technique used is based on the partitioning of samples into droplets by water-oil emulsion and the reading of the DNA signal in each droplet. Multiple eDNA targets can be specifically targeted using multiple primer and probe sets that are compatible. The advantages of using the ddPCR are: the absolute quantification, the sensitivity and the repeatability of the method.

Published: February 2024

Pilihan Raya Umum (PRU) ke-15, 2022 dilihat berlangsung dalam keadaan tergesa-gesa dan pertikaian orang ramai dan ahli politik terutamanya pihak pembangkang. Namun PRU tersebut tetap diadakan sehingga selesai tanpa sebarang insiden yang tidak diingini. Ramai pihak yang menjangkakan bahawa keputusan PRU-15 bakal menghasilkan tiadanya parti politik yang berjaya mendapat majoriti mudah namun BN dijangkakan akan mendapat jumlah kerusi Parlimen yang tertinggi. Namun keputusan PRU-15 menunjukkan bahawa PH mendapat jumlah kerusi Parlimen yang tertinggi, diikuti PN dan kemudiannya BN. PN berjaya mendapat sokongan daripada pengundi Melayu tertinggi, diikuti BN, PH dan yang terakhir GTA. Justeru, artikel ini membincangkan mengenai faktor sokongan pengundi etnik Melayu terhadap Perikatan Nasional (PN) dalam Pilihan Raya Umum (PRU) ke-15, 2022. Kajian ini menggunakan kaedah kualitatif iaitu analisis kepada maklumat sekunder iaitu penulisan jurnal, bahan seminar dan buku akademik yang berkenaan. Hasil kajian mendapati bahawa antara faktor sokongan pengundi Melayu terhadap PN adalah kepimpinan PN (PAS dan BERSATU) yang dilihat bersih dan lain-lain. Justeru, faktor sokongan tersebut perlu dijadikan iktibar seterusnya gerak kerja politik susulan bagi menawan sokongan pengundi Melayu yang secara keseluruhannya masih mendominasi politik pilihan raya di negara ini.
