Published: May 2022

Abstract
Under the action of freeze-thaw erosion, slopes in permafrost regions frequently suffer from geological disasters. The unique properties of soil-rock-mixture slopes further complicate this freeze-thaw stability problem. To study the effects of freeze-thaw erosion on the stability of soil-rock-mixture slopes, several indoor tests were first carried out on the specimens collected from the target bare slope at the K105+750~K105+850 section of the Ali River to the Kubuchun Forest Farm along National Highway 332 in permafrost regions of Greater Khingan Mountains, and then, according to the test results, damage theory, strength reduction method, Python script, and ABAQUS numerical analysis software, the slippage and safety factor of the bare slope under freeze-thaw cycles were obtained, and finally, the damage degree of freeze-thaw erosion to the bare slope was quantified. To improve the stability of bare slope in the freeze-thaw environment, the composite ecological slope protection measures of arched skeleton + three-dimensional net + grass planting were finally selected, and its feasibility is verified with the help of on-site monitoring and numerical simulation; then, the long-term freeze-thaw stability of the slope after revetment was studied. Key findings indicated that (1) the threshold between soil and rock in the target slope was 5 mm, the soil-to-rock mass and volume ratios of the slope were 55.04% : 44.96% and 69.38% : 30.62%, respectively. (2) After the 150 freeze-thaw cycles, the peak strength and elastic modulus of the specimens decreased 59.7% and 79.50%, respectively. (3) Meanwhile, the freeze-thaw damage was 0.79. (4) The slope safety factor was inversely proportional to the number of freeze-thaw cycles. The target bare slope was unstable after 150 freeze-thaw cycles, and the safety stability reduction rate was 41%. (5) Compared with the bare slope, the shallow horizontal slip of the slope after revetment decreased from 1.528 m to 4.971 cm, and the slope safety factor increased from 0.997 to 4.501, which shows that the slope protection measures are initially feasible. In addition, the numerical analysis results are consistent with the field monitoring data, and the error between the two is ≤2.01%, which proves the rationality of the numerical model established in this paper and provides data support for subsequent research.
Neodymium Isotope Constraints on the Origin of TTGs and High-K Granitoids in the Bundelkhand Craton, Central India: Implications for Archaean Crustal Evolution
Authors: Joshi Kumar Batuk , Singh Sunil Kumar , Halla Jaana , Ahmad Talat , Rai Vinai K. 
Published: May 2022

Abstract
The Bundelkhand craton in central India consists mainly of abundant high-K granitoids formed at the Archaean-Proterozoic boundary and several enclosed rafts of TTGs (tonalite-trondhjemite-granodiorites) up to 3.5 Ga. Therefore, the Bundelkhand craton is a key locality for studies on Archaean crustal growth and the emergence of multisource granitoid batholiths that stabilised a supercontinent at 2.5 Ga. Based on their geochemical characteristics, the high-K granitoids are divided into low silica–high Mg (sanukitoids and hybrids) and high silica–low Mg (anatectic) groups. We aim to provide new insights into the role of juvenile versus crustal sources in the evolution of the TTG, sanukitoid, hybrid, and anatectic granitoids of the Bundelkhand craton by comparing their key geochemical signatures with new Nd isotope evidence on crustal contributions and residence times. The ages and geochemical signatures as well as εNd(t) values and Nd model ages of TTGs point towards partial melting of a juvenile or short-lived mafic crust at different depths. Paleoarchaean TTGs show short crustal residence times and contributions from the newly formed crust, whereas Neoarchaean TTGs have long crustal residence times and contributions from the Paleoarchaean crust. This may reflect the transition from melting in a primitive oceanic plateau (3.4-3.2 Ga) in plume settings, resulting in a Paleoarchaean protocontinent, to 2.7 Ga subduction and island arc accretion along the protocontinent. The 2.5 Ga high-K granitoids formed at convergent subduction settings by partial melting of the mantle wedge and preexisting crust. Sanukitoids and hybrid granitoids originated in the mantle, the latter showing stronger crustal contributions, whereas abundant anatectic granitoids were products of pure crustal melting. Our Nd data and geochemical signatures support a change from early mafic sources to strong crust-mantle interactions towards the A-P boundary, probably reflecting the onset of supercontinent cycles.
Comprehensive Investigation of the Petrophysical and Two-Phase Flow Properties of the Tight Sandstone in Yanchang Formation, Ordos Basin, China: Insights from Computed Tomography Imaging and Pore Scale Modelling

Published: May 2022

Abstract
Accurate determination of petrophysical and fluid transporting properties of rocks is essential for many engineering applications. In this paper, microcomputed tomography (CT) imaging technique is adopted to image the microstructure of tight sandstones drilled from Chang-7 member in Yanchang Formation. The pore geometry, pore-throat size distribution, pore connectivity, and tortuosity of the pore-throat structure are quantitatively characterized by extracting the pore network model (PNM). Direct numerical simulation (DNS) approach is applied on the segmented CT images to investigate the anisotropic permeability of tight sandstones. In addition, the unstructured mesh model of the pore space is reconstructed, and the pore scale immiscible two-phase flow is simulated by computational fluid dynamics (CFD) using the volume of fluid (VOF) model. The results indicate that the pore-throat system of tight sandstone reservoirs is mainly composed of discontinuous intergranular pores and grain margin microfractures with poor connectivity and diverse pore morphology. The two-phase flow simulations indicate that the strong heterogeneity of pore-throat structure can lead to obvious fingering phenomenon of the injected fluid, which reduces the sweep efficiency and the oil recovery as well. The residual fluids are mainly trapped in tiny throats and dead-end pores. It is found that the digital rock analysis based on CT imaging can be a cost-effective and time-saving alternative to routine core analysis of tight sandstone reservoirs.
Internet-Based Intervention Compared to Brief Intervention for Smoking Cessation in Brazil: Pilot Study
Authors: Machado Nathalia Munck , Gomide Henrique Pinto , Bernardino Heder Soares , Ronzani Telmo Mota 
Published: May 2022

Background
Smoking is still the leading cause of preventable death. Governments and health care providers should make available more accessible resources to help tobacco users stop.

Objective
This study describes a pilot longitudinal study that evaluated the efficacy of an internet-based intervention compared to the brief intervention for smoking cessation among Brazilians.

Methods
Eligible participants were recruited and randomly allocated to one of the two interventions. Measures were drawn by comparing cessation rates, motivation scores, and sought treatment between groups, assessed 1 and 3 months after the intervention. Inferential analysis was performed to compare the participants’ characteristics, and the intention to treat was calculated.

Results
A total of 49 smokers were enrolled in this study (n=25, 51% in the brief intervention group; n=24, 49% in the internet-based intervention group). Mean age was 44.5 (SD 13.3) years; most were male (n=29, 59.2%), had elementary school (n=22, 44.9%), smoked 14.5 cigarettes per day on average (SD 8.6), and had a mean score of 4.65 for nicotine dependence and 5.7 for motivation to quit. Moreover, 35 (71%) participants answered follow-up 1, and 19 (39%) answered follow-up 2. The results showed similar rates of cessation and reduction for both intervention groups.

Conclusions
The internet-based intervention was slightly more effective for smoking cessation, while the brief intervention was more effective in reducing the number of cigarettes smoked per day. This difference was small and had no statistical significance even after adjusting for intention-to-treat analysis. These results should be interpreted with caution, especially due to the small sample size.

Authors: Alkhateeb Nazdar Ezzaddin , Dauod Ali Shakir , Shabila Nazar  P , Al-Dabbagh Ali A 
Published: May 2022

Objectives: This study aimed to assess the students and faculty staff attitude for e-learning at the emergence of COVID-19.
Methods: A prospective cross-sectional Google form based online survey was conducted at a medical university in Iraq between March and April 2020. The online survey was distributed to a sample of 190 faculty staff and 1706 students of a medical university in Iraq. Knowledge and attitudes towards e-learning and perceived barriers to implementing e-learning among participants were the primary outcome measures.
Results: The majority of students had a negative view of the simplicity of using e-learning compared with higher agreement among faculty staff. Most students disagreed with most aspects of the usefulness or strengths of e-learning. Both students and faculty staff agreed that e-learning faces challenges, including poor internet connectivity (79%) and computer literacy (71%). The highest percentage of the students (42.8%) preferred to have paper examinations in the study halls for the final written assessment. The percentages of the faculty staff who preferred paper examination in the study halls (31.6%), online assessment (31.1%), and delay assessment for the following year (33.2%) were almost similar.

Conclusion: The students and faculty staff are not ready for e-learning, with technical inadequacies being the main barrier. Since the COVID-19 pandemic has significantly disrupted medical education, proper technical and institutional foundations are essential for successful e-learning, especially during social distancing measures.

Authors: Al-Tu’ma Fadhil Jawad , Al-Maiyaly Zahraa Abdul Adheem 
Published: May 2022

Objective: This study aimed to investigate the relation between the risk of (PRKCB-1504 C/T) gene polymorphisms and diabetic nephropathy pathogenesis and its association with its levels and some other biomarkers in serum of Iraqi diabetic nephropathy patients.
Methods: A cross-sectional study was performed on 130 samples obtained from Al-Hussein Teaching Hospital / Kerbala – Iraq during Feb., 2020 to March. 2021. Seventy three patients of them with type 2 diabetes mellitus (T2D) and the remaining patients with type 2 diabetes mellitus with nephropathy complications (DN). Phenotypic analysis included determination of protein kinase C (PKC) activity levels, HbA1c%, serum insulin levels and renal function tests. Five ml of whole blood was obtained from each patients, 4.0 ml was centrifuged for serum separation used for biomarkers determinations and the remaining 1.0 ml was used for genomic DNA extraction for molecular analysis and polymorphism of PRKCB (rs3760106) by allele specific-amplification refractory mutational system-polymerase chain reaction (allele specific ARMS-PCR), followed by electrophoresis on 1% agarose gel. Various statistical analyses were applied to analyze the obtained data.
Results: The amplification of the PRKCB gene gives one genotypes as indicated by (200 bp) bands for those with homozygous wild type (CC), homozygous mutant (TT) genotypes and two genotypes bands (200 bp) for those with heterozygous (CT). Genotype frequencies of rs3760106 polymorphism were found to be consistent with Hardy–Weinberg equilibrium. Allele frequencies (23.3 %, 26.7 %, 50 %) of CC, CT, TT in cases of DN group. While the frequencies in the non-DN group were (30 %, 45%, 25%) and for healthy control group were (50%, 33.4%, 16.6%) for wild, heterozygous, and homozygous in an order. In healthy control group, the risk of diabetic nephropathy was significantly higher among carriers of T allele under codominant TT (OR=6.42, 95%CI=(1.66-24.85), P=0.007), dominant CT+TT (OR=3.2, 95%CI = (1.08-9.95),P=0.03) and recessive model (OR=5, 95%CI = (1.51-16.56), P=0.008) while in T2DM without nephropathy the risk of diabetic nephropathy was significantly higher among carrier of T allele under recessive model (0R=3, 95%CI = (1.09-28.25), P= 0.003). Serum level of PKC-B1 activity was significantly higher among DN group than T2DM and control groups (43.35 ± 18.69, 30.35 ± 11.96, 27.42 ± 10.31, P=0.001), also PKC-B1 activity in DN group was significantly correlated with fasting blood glucose, HOMA-IR and renal function tests such as GFR, urea and creatinine.
Conclusion: This study indicates that the PRKCB (C/T-1504) rs3760106 single nucleotide polymorphism was significantly associated with increased diabetic nephropathy susceptibility of Iraqi patients with T2DM and serum level of PKCB activity was associated with increase the risk of diabetic nephropathy complications.

Authors: Mo Xiaoyan , Lv Jiajia , Shao Jie 
Published: May 2022

Aim: The aim of the present study was to explore the tolerance
march in children and establish probable factors that affect the
prognosis of an egg allergy (EA). Methods: Two hundred children
6 months to 2.5 years old with atopic dermatitis (AD) were recruited
into our study from 2018 to 2019. EA was diagnosed based on medical
history, the skin prick test (SPT), and the oral food challenge test
(OFC) ,EA was diagnosed in 78，among those, 7 were allergic only to egg
yolk (OnlyEYA), 20 to egg white (OnlyEWA), and 51 to whole egg (WEA).
Logistic regression analysis was used to detect the disease course and
related risk factors of outcomes. The receiver operating characteristic
curve was used to establish a predicting model. Results:The
Scoring Atopic Dermatitis score in the WEA group was more severe and
persistent than that in the other groups. Forty-three cases of EA
developed clinical tolerance (average age, 32.3 ± 8.7 months). The
tolerance rate of EYA was 75.9% and EWA was 56.3%. The SPT wheal
diameter at initial diagnosis (SPT ) was the risk
factor for persistent EA. The SPT wheal diameter after 6 months (△SPT
) in the tolerant group decreased markedly compared
to that in the persistent EA group. Tolerance was higher when △EW-SPT
≥ 39.5% or △EY-SPT ≥ 27%.
Conclusion: The initial SPT and SPT
values were significantly correlated with and can
predict outcomes of EA. Key words: Egg allergy, atopic
dermatitis, outcome, related factors.

Placement, Retention, and Success: A Longitudinal Study of Mathematics and Retention
Authors: Parker Melanie 
Published: May 2022

ABSTRACT
This study looked at undergraduate students' scores on a mathematics placement exam, mathematics courses taken and grades received, and persistence toward a degree. It was determined that a student's timely progress toward a four-year degree is influenced by the student's initial score on the mathematics placement exam and by subsequent performance in mathematics courses. Analysis of longitudinal data suggests that students tend to maintain the level of mathematics skills with which they entered college, and students who graduate in four years seem to increase their knowledge of elementary mathematics during this time.
History, Self-Awareness, and the Core Curriculum
Authors: Rodgers Thomas E. 
Published: May 2022

ABSTRACT
This article argues that core curriculum history surveys should promote critical reading and thinking skills, a basic knowledge of history, and a sense of self-awareness. Self-awareness is suggested as an alternative to attempts to promote student civic character by such means as service education. It also outlines the interconnection of teaching and researching history and how a core curriculum course's structure and teaching approach should be rooted in the nature of its discipline rather than standardized teaching methodologies.
