Authors: Zhu Zhaowei , Peng Zhenyu , Xing Zhenhua 
Published: May 2022

Objective:Living alone is often associated with reduced social support. However, there are limited data on the relationship between living alone and cardiovascular events or hypoglycemia in patients with type 2 diabetes mellitus (T2DM). This study reports a post-hoc analysis of the “Action to Control Cardiovascular Risk in Diabetes (ACCORD)” study.Research Design and MethodsThe Cox proportional hazard models were used to compare the hazard ratios (HRs) for the adverse health events selected as primary endpoints in the study participants; these were compared between those living alone and those living with others. The primary outcomes were hypoglycemia requiring any assistance (HAA), hypoglycemia requiring medical assistance (HMA), and major cardiovascular events (MACEs, including cardiac death, non-fatal myocardial infarction (MI), and non-fatal stroke). Our study included 10,249 participants (2,078 living alone) with a follow-up period of 4.91 ± 1.22 years.ResultsAfter a multivariable adjustment, the risk of HAA, HMA, and MACEs did not differ significantly between participants living alone and those living with others (HAA, HR: 0.88, 95% CI: 0.75–1.04, P = 0.13; HMA, HR: 1.11, 95% CI: 0.92–1.34, P = 0.26; MACEs, HR: 0.98, 95% CI: 0.80–1.19, P = 0.82). Participants living alone had higher levels of glycated hemoglobin in the middle follow-up period than those living with others.ConclusionsIn patients with T2DM, living alone did not increase the risk of cardiovascular events (cardiac death, non-fatal MI, or non-fatal stroke) and hypoglycemia. Patients living alone had higher Hb1AC levels than those living with others. Clinicians should consider an effective blood glucose control regardless of their living arrangement.

In recent years, UHP self-compacted concrete is an innovative category of concrete that has attached a lot of attention because of its higher durability and compressive strength than conventional concrete. So, to overcome the cost of preparation of UHPC and preservation of high-strength deformation and rheological characteristic of self-compacting concrete when replacing a part of expensive cement with three types of production waste. In addition, the problem of reducing environmental pollution is solved. In this study. recycled glass (GP) and lime (LP) powder were used as substitution materials in the manufacture of the UHPSCC. The flowability of UHPSCC was measured by slump flow, T50, V-funnel tests as an indication for the capability of filling and J-ring tests as an indication for the capability of passing. Furthermore, durability and mechanical properties were investigated. The elevated temperature effect was investigated on several UHPCSCC samples with glass (GP) and lime (LP) powder. The test results showed that the incorporation of GP and LP partially replaced cement improved the flowability of UHPSCC. The compressive, tensile, and flexural strength were enhanced by using GP till 20% replacement of cement also, the compression strength values were highly improved by using LP replacement of cement at different ages for (hot and normal curing). The highly compressive strength values for UHPSCC mixes with a 20% replacement ratio of GP and LP as cement replacement materials were 119.0 and 128.8 MPa under hot curing regimes and increased by 6.25% and 9.62%, respectively, than that of similar mixes under normal curing regimes at 90 days. The highly splitting and flexural strength values for UHPSCC 7 mix with 20% replacement level of LP and UHPSCC 9 mix with 20% replacement level of LP and GP were reported at 11.80 and 17.85 MPa which increased by 24.20% and 58.60%, respectively, compared to the control mix.

Published: May 2022

Climate change and the increase in the availability of nutrients in aquatic environments have increased the occurrence of cyanobacterial blooms which can produce cyanotoxins such as cylindrospermopsin (CYN). Activated carbon adsorption have been proved to be efficient for CYN removal. In the present study, a carbon with high CYN adsorption capacity was identified between two granular activated carbons. For this carbon was estimated the operating time of a full-scale granular activated carbon column under different empty bed contact times (EBCT). The fixed-bed breakthrough was estimated using the Homogeneous Surface Diffusion Model (HSDM). Wood carbon showed greater capacity to remove CYN. The experimental equilibrium data best fitted Langmuir isotherm model, in which wood carbon had a maximum adsorption capacity of 3.67 μg/mg and Langmuir adsorption constant of 0.2791 L/μg. The methodology produced satisfactory results where the HSDM simulated the fixed-bed breakthrough with a coefficient of determination of 0.89, to the film diffusion coefficient (Kf) of 9 × 10−6 m/s and surface diffusion coefficient (Ds) of 3 × 10−16 m2/s. It was observed that the increase in EBCT promotes a reduction in the carbon use rate. The best carbon use rate found was 0.43 kg/m3 for a EBCT of 10 min and breakthrough time of 183.6 h.

GPS Measurements of Precipitable Water Vapor Can Improve Survey Calibration: A Demonstration from KPNO and the Mayall z-band Legacy Survey

Abstract
Dual-band Global Positioning Satellite (GPS) measurements of precipitable water vapor (PWV) at the Kitt Peak National Observatory predict the overall per-image sensitivity of the Mayall z-band Legacy Survey (MzLS). The per-image variation in the brightness of individual stars is strongly correlated with the measured PWV and the color of the star. Synthetic stellar spectra through TAPAS transmission models successfully predict the observed PWV-induced photometric variation. We find that PWV absorption can be well approximated by a linear relationship with (airmass × PWV)0.6 and present an update on the traditional treatment in the literature. The MzLS zero-point sensitivity in electrons s−1 varies with a normalized-mean absolute deviation of 61 mmag. PWV variation accounts 23 mmag of this zero-point variation. The MzLS per-image absolute sensitivity decreases by 40 mmag per effective mm of PWV. The overall gray offset portion of this variation is corrected by the calibration to a reference catalog. But the relative calibration error between blue (r − z < 0.5 mag) versus red (1.2 mag < r − z) stars increases by 0.3–2 mmag per effective mm of PWV. We argue that GPS systems provide more precise PWV measurements than using differential measurements of stars of different colors and recommend that observatories install dual-band GPS as a low-maintenance, low-cost, auxiliary calibration system. We extend our results of the need for well-calibrated PWV measurements by presenting the calculations of the PWV photometric impact on three science cases of interest: stellar photometry, supernova cosmology, and quasar identification and variability.

Abstract
Ion escape from the atmosphere to space is one of the most likely reasons to account for the evolution of the Martian climate. Based on three-dimensional multifluid magnetohydrodynamic simulations, we investigated the impact of the magnetic inclination angle on O+ escape at low altitudes of 275–1000 km under the typical solar wind conditions. Numerical results showed that an outward ion velocity in the direction opposite to the electromagnetic (EM) force results in weak outward flux and leads to ions becoming trapped by the horizontal magnetic field lines at the local horizontal magnetic equator. Much of the EM force can be attributed to the Hall electric force. In the region of high absolute magnetic inclination angle, the outward ion velocity has the same direction as the EM force, which increases the outward flux and causes ions to diffuse upward along open magnetic field lines to higher altitude. In addition, the EM force is mainly provided by the electron pressure gradient force and the motional electric force. Global results for the magnetic inclination angle indicate that the strong crustal field regions in the southern hemisphere are mainly occupied by magnetic field lines with high absolute magnetic inclination angle, while horizontal field lines are dominant in the northern hemisphere, which leads to a higher O+ escape rate in the Martian southern hemisphere than in the northern, from altitudes of 275 to 1000 km. This is a significant advance in understanding the impact and mechanism of the Martian magnetic field directions on ion escape.

Inscrit dans le champ de recherche de la NoS (Nature Of Science) et ayant pour thème la modélisation, notre travail est centré sur les pratiques déclarées d’enseignants de physique travaillant au sein d’institutions post-baccalauréat de différents secteurs (physique-généraliste, physique-professionnelle) de deux pays (France et États-Unis). Pour caractériser, dans le cadre des PCK (Pedagogical Content Knowledge), leurs pratiques de modélisation associées à l’enseignement de l’écoulement interne d’un fluide, nous explorons la dimension liée aux stratégies d’enseignement adoptées. À travers l’analyse de contenu thématique des 15 entretiens, nous mettons en particulier en évidence une hétérogénéité de la population « généraliste-physique » en termes de catégories de PCK liées aux modèles et aux contextes et ce, indépendamment du pays d’exercice de l’enseignant.
La théorie des deux mondes, un outil d’analyse d’une pratique enseignante innovante à l’université : le cas de l’enseignement de la physique par l’escalade
Authors: Hosson (de) Cécile , Elias Florence 
Published: May 2022

Cet article vise à analyser les effets d’une collaboration entre deux enseignantes-chercheuses, l’une chercheuse en physique de la matière condensée (EC1), l’autre en didactique de la physique (EC2), réunies autour d’un enseignement original « la physique de l’escalade ». La collaboration se donne pour objectif d’enrichir la capacité d’analyse d’EC1 sur cet enseignement. Pour cela, nous nous plaçons dans le cadre de la didactique professionnelle afin de développer chez EC1 une aptitude à conceptualiser son action et son réel pédagogique. La théorie des deux mondes vient en appui de ce processus de développement et joue le rôle d’interface entre EC1 et EC2. Spécifiquement nous montrons le rôle joué par la mobilisation de la théorie des deux mondes dans le processus de développement conceptuel d’EC1 en pointant quelques élucidations de difficultés ressenties par EC1 et certaines de leurs conséquences prospectives. D’autres élucidations se font jour qui concernent cette fois EC2 et qui forment autant de pistes pour la recherche en didactique et pour la formation des enseignant.e.s du supérieur.

Authors: Kılinç G , Çetin M , Ertunç FÜE , Ateşçi AA 
Published: May 2022

Aim:
The aim of this study was to investigate the pit and fissure morphology of the permanent first molars (PFMs) in the dentition of 7- to 12-year-old patients in Turkish children.

Patients and Methods:
The study was conducted on 706 patients who attended the Dokuz Eylul University Child Clinic. Examinations of the patients were carried out with dental unit light, mouth mirror, and probe by two dentists. Age, gender, plaque scores, pit and fissure morphology, caries, restorations, and missing teeth were recorded.

Results:
Of the 706 patients included in this study, 441 (62.5%) of them have affected PFMs. Intermediate type fissure morphology (57.5%) was seen as the most common type. A positive correlation was observed between the age and the caries experience (p = 0.000). Patients with deep pits and fissure morphology have more caries affected teeth than patients with shallow pit and fissure morphology, and the difference was statistically significant (p = 0.000). Patients with deep pits and fissure morphology have significantly more plaque accumulation on PFMs compared to the patients with shallow and intermediate fissure morphology (p = 0.000).

Conclusions:
Despite the limitations of the study, we can conclude that the patients with deep pit-fissure morphology are more susceptible to caries development and plaque accumulation than the patients with shallow and intermediate type pit and fissure morphology.

Authors: Şengel N , Karabulut G , Kavuncuoğlu D , Selmi N H , Şivgin V , Toprak ME 
Published: May 2022

Background and Aim:
Nasotracheal intubation is the main route to secure the airway in oral and maxillofacial surgery patients. This study was aimed to compare the intubation times and glottis visualization of McGrath video laryngoscope with the Macintosh laryngoscope for routine nasotracheal intubation.

Materials and Methods:
Records of seventy-one ASA (American Society of Anesthesiologists) I-II patients were evaluated and allocated into two groups (McGrath video laryngoscope (VL) and Macintosh groups). Intubation times, modified intubation difficulty scale (MIDS) scores, and hemodynamic parameters (heart rate and mean arterial pressure) were compared after the anesthesia induction and the intubation.

Results:
Mean intubation time in the McGrath group (24.9 ± 5.9 seconds) was significantly lower than that of the Macintosh group (28 ± 6.2 seconds; P = 0.037). Magill forceps were needed less in the McGrath group compared to the Macintosh group (13.89% vs. 42.86%; P = 0.009). Total MIDS scores were similar (P = 0.778). There was no significant difference in the hemodynamic parameters between the groups.

Conclusion:
The McGrath VL significantly reduced the intubation time and the use of Magill forceps compared with Macintosh direct laryngoscope and can be utilised effectively for routine nasotracheal intubation.

Published: May 2022

ABSTRACT. Aerospace and automotive industries employ Ti4Al4Mo2Sn material in many applications due to its properties of better strength to weight ratio and high corrosion resistance. Ti4Al4Mo2Sn finds itself difficult to cut materials due to its physical and chemical properties and is prone to more heat generation during machining. The more generation of heat affects the machined material surface quality and other related properties. In this investigation, the thermal conductivity and stability of Al2O3/Water based nanofluids are studied to select the best composition of nanofluid for transferring heat. The thermal conductivity and stability of the nanofluid for a duration of 30 days are computed by employing the KD2 thermal property meter and pH meter, respectively. Thermal conductivity and stability of the Water/4.5 vol.% Al2O3 nanofluid are found to be better than other combination of nanofluids. In the present study, optimizing the micro milling process parameters on Ti4Al4Mo2Sn material with Minimum quantity cooling lubrication (MQL) is focused. The input parameters selected for this micro milling process are spindle speed, feed rate, depth of cut and Water/4.5vol.% Al2O3 nanofluid and the output parameters selected are cutting forces in X(Fx) and Y(Fy) directions, tool wear rate (TWR) and surface roughness (SR). The optimization is done with the help of grey relational analysis (GRA) by using L9 Orthogonal Array (OA) Taguchi design. The obtained sequence of influencing parameters are feed rate per tooth, Al2O3nanofluid, spindle speed and depth of cut. The percentage of grey relational grade (GRG) for prediction and experimental is 0.721 and 0.957. The percentage of improvement of GRG is 12.46.
