Abstract
Using the extended halo-based group finder developed by Yang et al., which is able to deal with galaxies via spectroscopic and photometric redshifts simultaneously, we construct galaxy group and candidate protocluster catalogs in a wide redshift range (0 < z < 6) from the joint CFHT Large Area U-band Deep Survey and Hyper Suprime-Cam Subaru Strategic Program deep data set. Based on a selection of 5,607,052 galaxies with i-band magnitude m

i
< 26 and a sky coverage of 34.41 deg2, we identify a total of 2,232,134 groups, of which 402,947 groups have at least three member galaxies. We have visually checked and discussed the general properties of these richest groups at redshift z > 2.0. By checking the galaxy number distributions within a 5–7 h
−1Mpc projected separation and a redshift difference Δz ≤ 0.1 around those richest groups at redshift z > 2, we identify lists of 761, 343, and 43 protocluster candidates in the redshift bins 2 ≤ z < 3, 3 ≤ z < 4, and z ≥ 4, respectively. In general, these catalogs of galaxy groups and protocluster candidates will provide useful environmental information in probing galaxy evolution along cosmic time.
Infrared Line Emissions from Atoms and Atomic Ions in NGC 7027: Improved Wavelength Determinations for Infrared Metal Lines and a Probable Detection of Zn5+
Authors: Neufeld David A. 
Published: June 2022

Abstract
An infrared L- and M-band spectral survey, performed toward the young planetary nebula NGC 7027 with the iSHELL instrument on NASA’s Infrared Telescope Facility (IRTF), has revealed more than 20 vibrational lines of the molecules HeH+, H2, and CH+ and more than 50 spectral lines of atoms and atomic ions. The present paper focuses on the atomic line emissions, the molecular lines having been discussed in two previous publications. The atomic lines detected with high confidence in the 2.951–5.24 μm region covered (incompletely) by this survey comprise (1) six collisionally excited lines of metal ions that had previously been identified in astrophysical nebulae but for which the present observations provide the most accurate wavelength determinations obtained to date; (2) a spectral line at 4.6895 μm, not previously reported, for which the probable identification is the 4

Née à Paris en 1908, Henriette Huchard entre à l’École nationale des beaux-arts de Paris et obtient en 1935 les diplômes de professorat de dessin de l’État et de la Ville de Paris. Parallèlement à ses activités d’enseignement, ses travaux artistiques l’amènent à utiliser une diversité de supports et de matériaux notamment l’aluminium ; c’est ainsi qu’en 1971 elle se voit confier une commande dans le cadre de la rénovation du grand salon de la classe touriste du paquebot France . Il s’agit d’une décoration constituée de deux grands panneaux, l’une des quatre œuvres d’art ajoutée durant l’exploitation de ce navire sous pavillon français.
Devenir pauvre : du revenu au ressenti
Authors: Richard Éléonore 
Published: June 2022

Les chercheurs en économie s’accordent généralement pour dire qu’une mesure unique de la pauvreté, qu’elle soit relative, absolue, objective ou subjective, ne suffit pas pour saisir la réalité complexe qu’elle recouvre. À partir d’un échantillon de ménages français de l’enquête Statistiques sur les ressources et les conditions de vie (SRCV) menée par l’Institut national de la statistique et des études économiques (Insee) entre 2010 et 2016, cette étude montre que le bien-être subjectif des individus est corrélé à l’entrée et à la sortie de la pauvreté en conditions de vie, mais que les individus ne semblent pas affectés par les transitions vers et hors la pauvreté monétaire à 60 % du revenu médian. Il apparaît que seul le franchissement du seuil monétaire à 80 % du revenu médian est significatif pour les individus interrogés, faisant ainsi de ce seuil une ligne subjective de pauvreté. Certains événements sociodémographiques (séparation, chômage…) semblent précipiter l’entrée dans la pauvreté à ce seuil, jugé critique par les individus, et qui représente environ 30 % de la population française.

Published: June 2022

Fatigue life has to be considered in the design of many concrete structures at various stress levels and stress ratios. Many flexural fatigue test results of plain normal-weight concrete are available in the literature and almost every set of test results provides different fatigue equations. It is necessary, though, to have a common fatigue equation to predict the design fatigue life of concrete structures under flexural load with reasonable accuracy. Therefore, a database of flexural fatigue test results was created for concrete with strengths ranging from 25 to 65 MPa; this database was used to derive new fatigue equations (Wöhler fatigue equation and S-N power relationship) for predicting the flexural fatigue life of normal-weight concrete. The concept of equivalent fatigue life was introduced to obtain a fatigue equation using the same stress ratio. A probabilistic analysis was also carried out to develop flexural fatigue equations that incorporate failure probabilities.
Flipped Classroom for Pharmacology Teaching in a Malaysian Medical School using Online Tools during the COVID-19 Pandemic: Knowledge Gained and Student Perception
Authors: Heethal Jaiprakash  
Published: June 2022

Introduction: The usage of a flipped classroom to instruct medical students is becoming more common. During the COVID-19 epidemic, this method of teaching and learning proved to be effective. This study aims to analyse the knowledge gained and perceptions of medical students who were taught pharmacology in a flipped classroom utilising online tools.
Methodology: A total of 50 second-year medical students took part in the research. Local anaesthetics and adverse drug reactions were the two topics covered in the flipped classroom. A few weeks before the session, pre-reading materials were distributed, which included voice-over PowerPoint videos and AMBOSS links. Students were given pre and post-tests using Microsoft forms to assess their knowledge gained during the face-to-face session. Higher-order thinking questions were uploaded as a Kahoot session, and the questions were also posted using Microsoft PowerPoint in an interactive session. A validated questionnaire was used to collect feedback, and the responses were graded on a 4-point Likert scale. Descriptive statistics were used to analyse the data.
Results: There were 18 females and 32 males among the 50 students. The students' average age was 21.4±0.6 years. When the pre and post-test scores were compared, statistically significant results were obtained (P-value .000). The students had a favourable attitude about flipped classrooms. Most students said that the flipped classroom increased their understanding of the subject (mean score 3.760.44). They also thought the flipped classroom was a fun way to learn (mean score 3.710.47). The overall perception of the flipped classroom was excellent (53%).
Conclusion: The knowledge gained by the students during the flipped classroom session in pharmacology was significant. The students had a favourable opinion of the flipped classroom method of teaching pharmacology.

Published: June 2022

Background: Studies indicate the presence of cardiovascular disease risk amongst patients with uterine fibroids and polycystic ovarian syndrome.Aim: The researchers aimed to examine the prevalence of cardiovascular disease risk factors and independent predictors of insulin resistance (IR) amongst women with abnormal uterine bleeding (AUB).Methods: This observational study examined 77 premenopausal subjects with AUB. Their medical history, body mass index (BMI), waist–hip ratio (WHR), fasting insulin (FI), haemoglobin A1c, creatinine and lipids were evaluated. Subjects were subdivided using insulin levels and compared. Insulin resistance was defined at two FI levels: 10 μU/mL and 15 μU/mL.Results: A total of 91% of participants had smoking history, 62% had a WHR 0.80, 45% were obese and most had dyslipidaemia. In all, 38% – 66% were insulin resistant, depending on cut-off used. At FI 10 μU/mL, subjects were significantly more likely to have a WHR 0.8, be obese and have low HDL. At FI 15 μU/mL, subjects were significantly more likely to have low HDL, elevated triglycerides, a WHR 0.8 and be obese. Univariate analysis showed significant associations between IR in AUB and BMI, WHR and HDL for both FI cut-offs. Multivariate analysis using the lower FI cut-off revealed BMI and WHR were significant independent predictors of IR in AUB.Conclusion: This study reveals the prevalence of IR (66%) and other predictors of cardiovascular disease are greater in AUB in this population than the general US population. Body mass index and WHR are independent predictors of IR in AUB. Low HDL, elevated triglycerides and ethnicity are also significantly associated with IR in AUB depending on the definition used.
Utility of Renal Resistive Index in Children with Nephrotic Syndrome
Authors: Swarnim Swarnim , Naj Mohsina , Mantan Mukta , Garg Anju 
Published: June 2022

Background:
Renal resistive index (RRI) is one of the Doppler parameters that provide information about arterial impedance. While its utility has been explored in chronic kidney disease and obstructive uropathy, its role in glomerular diseases remains less defined.

Aim:
This study aimed to measure RRI in children (6–18 years) with nephrotic syndrome, both steroid sensitive (SSNS) and steroid resistant (SRNS), currently in remission.

Setting and Design:
This cross-sectional study was done over 1 year at a tertiary care teaching hospital from March 2017 to March 2018.

Methods:
Renal Doppler ultrasound was done and RRI was measured at the main renal, arcuate, and interlobar arteries for both the kidneys during disease remission. Detailed information of disease type, biopsy, and therapy was recorded. Baseline biochemical investigations were done to confirm disease remission.

Results:
Fifty patients (25 each with SSNS and SRNS) were enrolled; the mean age was 12.6 years. The mean RRI at the interlobar and arcuate arteries was elevated in SRNS in all three poles of both the kidneys as compared to the SSNS with a significant difference at midpole (P = 0.04). RRI values were higher in children having focal segmental glomerulosclerosis (FSGS) compared to those with minimal change disease. The percentage of patients having an RRI value >0.6 was significantly higher in those who had received cyclosporine for >2 years as compared to those who received it for <2 years.

Conclusions:
Doppler RRI values were elevated for patients with SRNS compared to SSNS; changes were significant at the midpole of both kidneys. Children with FSGS and those on calcineurin inhibitors for more than 2 years are more likely to have higher RRI values.

Aim and Objectives of the Study:
The aim of the study was to assess the oral health status and treatment needs among Group D workers of four government hospitals in Bengaluru and the objectives of the study were to assess the prevalence of dental caries, periodontal health status, oral mucosal lesions, and treatment needs and to know the possible relationship between low socioeconomic status and this particular occupation with oral health status.

Materials and Methodology:
A total of 800 Group D workers were examined according to the WHO Basic Oral Health Survey Assessment Form 1997, and the required data were collected in a prepared format consisting of sociodemographic details, habits, oral hygiene practices, and few questions to assess their knowledge and awareness. The oral cavity of the workers was examined using CPI probe and mouth mirror plane.

Results:
About 283 (35.4%) workers had one or the other forms of oral mucosal lesions of these, majority (102; 12.8%) had Chewer's mucosa, 67 (8.4%) had smoker's melanosis, 58 (7.3%) had leukedema, 27 (3.4%) had leukoplakia, 17 (2.1%) had oral submucous fibrosis, 8 (1%) had smoker's palate, and 2 (0.3%) had lichen planus.

Conclusion:
The present study concludes that there is a strong relationship between poor oral health status and higher treatment needs with the low social class, low educational levels, and occupation.

Published: June 2022

Aim:
The aim of this study was to investigate the frequency of second mesiobuccal canal in maxillary first and second molars.

Materials and Methods:
Maxillary fifty first molars and fifty second molars were collected and embedded into plaster blocks. The teeth were photographed digitally from the occlusal aspect using a stereomicroscope under standard (×8) magnification. The occlusal portions of crowns were then sectioned at cement–enamel junction with slow-speed diamond disk. To gain straight line visibility, overhung dentin over the canal orifices was removed with safe-tip diamond bur. Once again, the teeth were photographed from their occlusal aspect under the same magnification and exposure conditions.

Results:
MB2 canals were detected 76% and 64% in first and second molars, respectively.

Published: June 2022

Aim:
The aim of this study was to evaluate the crestal bone level between alumina-blasted/acid-etched (AB/AE) surface-treated implant and calcium phosphate surface-treated implant” based on the radiological examination.

Materials and Methods:
An in vivo study was undertaken to evaluate the crestal bone loss on mesial and distal aspects of implants categorized into two groups with different surface treatments, Group A: AB/AE surface-treated implant and Group B: calcium phosphate surface-treated implant using standardized intraoral periapical at three different intervals, i.e., immediately after implant placement, at the end of 3, and 6 months after placing the implants. Statistical tests used were Student's unpaired t-test and ANOVA.

Results:
The bone loss was measured, and values were recorded immediately after implant placement, 3, and 6 months of placement.

Conclusions:
The use of calcium phosphate surface-treated implants minimizes crestal bone loss compared to AB/AE. This may increase the longevity of implants.

Published: June 2022

AIM OF THE STUDY: To analyse hospital incidence and in-hospital mortality of patients treated for abdominal aortic aneurysms in Switzerland.
METHODS: Secondary data analysis of case-related hospital discharge data of the Swiss Federal Statistical Office for the years 2009–2018. Patients who were hospitalised and surgically treated for nonruptured abdominal aortic aneurysms or hospitalised and treated for ruptured abdominal aortic aneurysms were included in the analysis. Standardised annual incidences rates were calculated using the European standard population 2013. In-hospital all-cause mortality rates were calculated as raw values and standardised for age, sex, and the van Walraven comorbidity score.
RESULTS: A total of 10,728 cases were included in this study, of which 87.1% were male. Overall, 22.7% of the patients presented with a ruptured abdominal aortic aneurysm; 46% of these cases were surgically treated whereas 54% received conservative therapy. The age-standardised cumulative hospital incidences for treatment of nonruptured abdominal aortic aneurysms were 2.6 (95% confidence interval 2.5–2.8) and 19.7 (19.2–20.1) per 100,000 for women and men, respectively; for ruptured aneurysms it was 0.4 (0.3–2.4) per 100,000 in women, and 2.7 (2.6–2.9) in men. The annual incidence rates were stable in the decade observed. The adjusted mortality rates for treatment of nonruptured aneurysms decreased from 5.5% (2.6–11.2%) in 2009 to 1.4% (0.5–3.6%) in 2018 in women, and from 2.4% (1.3–4.5%) in 2009 to 0.6% (0.2–1.5%) in 2018 in men. The adjusted mortality rates for treatment of ruptured abdominal aortic aneurysms remained high without relevant improvements for either sex over time: for women 32.4% (24.1–42.1%), for men 19.7% (16.8–22.8%).
CONCLUSIONS: The hospital incidence rates for nonruptured and ruptured abdominal aortic aneurysms remained unchanged in the decade observed. Compared with Germany, there was no evidence for a decrease in the annual incidence rates for ruptured abdominal aortic aneurysms in Switzerland. Mortality rates in the elective setting were low and decreased in the last decade but remained high in patients treated for ruptured aneurysms. Efforts to reduce the incidence of ruptured abdominal aortic aneurysms are needed to reduce aneurysm-related mortality in Switzerland.

Published: June 2022

Pengadilan Pajak sebagai bagian dalam sistem kekuasaan kehakiman juga menerapkan asas peradilan sederhana, cepat, dan biaya ringan. Prosedur sederhana ditujukan demi mempercepat waktu penyelesaian sengketa yang sehingga dapat meringankan biaya yang harus ditanggung. Namun pada praktiknya, di tahun 2019 setiap majelis pada bulan Januari 2020 tercatat 3.427 sengketa yang menjadi tunggakan. Hal tersebut menggambarkan adanya permasalahan dalam penyelesaian sengketa dan belum terwujudnya peradilan sederhana, cepat, dan biaya ringan. Permasalahan yaitu apa penyebab banyaknya sengketa yang menjadi tunggakan, serta akibat hukum yang ditimbulkannya? dan upaya apa yang dapat ditempuh agar tidak terjadi tunggakan sengketa di Pengadilan Pajak sehingga peradilan sederhana, cepat, dan biaya ringan dapat terwujud. Tujuan penelitian ini yaitu untuk menganalisa penyebab banyaknya sengketa yang menjadi tunggakan, serta akibat hukum yang ditimbulkan. Metode penelitian yang digunakan yaitu metode penelitian hukum sosiologi/empiris. Hasil analisis mencatat adanya 4.061 sengketa yang menjadi tunggakan pada bulan Juli 2020. Dapat disimpulkan bahwa hal tersebut disebabkan oleh jumlah hakim yang tidak sebanding dengan jumlah sengketa, tingkat kesulitan sengketa yang sangat beragam, pembuktian yang rumit, banyaknya berkas bukti yang harus diperiksa, ketidaksiapan para pihak untuk menjalani proses persidangan, pemanggilan para pihak dan/atau saksi-saksi yang memerlukan waktu lama, dan dilakukannya pembatasan bahkan peniadaan persidangan selama pandemi global Covid-19.

With age the structure of facial skin changes. Non-invasive procedures help maintain skin’s elasticity, the need for them exists in the 21st century too.
Aim. Was to ascertain the effect of non-invasive procedures on facial skin problems.
Research Methods. A qualitative investigation and oral survey were chosen. Two participants were chosen in the targeted selection: participant 1 (28 years old) was treated with the Darsonval apparatus; ultrasound procedures were chosen for participant 2 (56 years old).
Results and Conlusions. Following the procedures, the number of acnes decreased on both sides of the face of participant 1, sebum secretion was partly regulated, a network of capillaries on the cheeks diminished visually, the condition of facial skin improved. The expected results were partly achieved.
As to participant 2, mimic wrinkles, fine lines around the eyes and deeper wrinkles in the T zone were slightly reduced. Minimum results were achieved: a feeling of skin tension was removed, skin became softer, smoother, keratinisation reduced. Frequency of non-invasive procedures enabled the participants with skin problems to reach a positive result of skin changes, which was achieved faster in the case of participant 2.
