Authors: Немировский Юрий Владимирович , Тихонов Сергей Владимирович 
Published: October 2022

Рассматривается задача центрального растяжения однородного и многослойного бетонного стержня квазистатическими нагрузками. В качестве распределенной нагрузки принимается сила тяжести, действующая на стержень. Определены предельные нагрузки и удлинения стержня в зависимости от физических параметров стержня. При деформации ниже предельной упругой предполагается, что бетон деформируется линейно, в противном случае нелинейно неупруго. Приведены примеры расчетов по полученным соотношениям для слоистых стержней одинаковой массы, где в каждом слое могут быть реализованы различные марки бетонов.
The problem of central tension of a homogeneous and multilayer concrete rod by quasi-static loads is considered. The force of gravity acting on the rod is taken as a distributed load. The ultimate loads and elongations of the rod are determined depending on the physical parameters of the rod. At a deformation below the limiting elastic one, it is assumed that the concrete deforms linearly, otherwise it is non-linearly inelastic. Examples of calculations based on the obtained ratios for layered rods of the same mass are given, where different grades of concrete can be realized in each layer.

Abstract
Delayed planting of sugarcane crop after harvesting of seed is a common farming practice in all cane growing areas of Pakistan. This study was conducted to find out comparative effect of sugarcane seed having different harvesting or stalling period on productivity of sugarcane. The experiment was planted in randomized complete block design with split plot arrangement for two consecutive years. Three commercial sugarcane varieties viz. CPF 248, CPF 247 and CPF 246 were kept in main plots whereas cane setts staling; fresh, 3 days, 6 days & 9 days old stale cane setts were placed in sub-plots. The data revealed that sugarcane clones were differed significantly for most of biometric traits under study except cane yield whereas impact of cane setts stalling was also significant excluding for sugar contents. While, interactive effect of all treatment combinations for sugarcane clones and cane setts stalling was found significant except for CCS%. It was found that clone CPF 247 exhibited highest cane and sugar yield by planting fresh cane setts as against lowest for CPF 248 when planted with 9 days old stale cane setts during both years of experimentation. Better growth and yield related traits were predominantly attributed to planting of fresh cane seed having better germination, tillering and cane density.
Evolution of the Hub-filament Structures in IC 5146 in the Context of the Energy Balance of Gravity, Turbulence, and Magnetic Field

Published: October 2022

Abstract
We present the results of 850 μm polarization and C18O (3 − 2) line observations toward the western hub-filament structure (W-HFS) of the dark Streamer in IC 5146 using the James Clerk Maxwell Telescope SCUBA-2/POL-2 and HARP instruments. We aim to investigate how the relative importance of the magnetic field, gravity, and turbulence affects core formation in HFS by comparing the energy budget of this region. We identified four 850 μm cores and estimated the magnetic field strengths (B
pos) of the cores and the hub and filament using the Davis–Chandrasekhar–Fermi method. The estimated B
pos is ∼80 to 1200 μG. From Wang et al., B
pos of E-47, a core in the eastern hub (E-hub), and E-hub were reestimated to be 500 and 320 μG, respectively, with the same method. We measured the gravitational (E
G), kinematic (E
K), and magnetic energies (E
B) in the filament and hubs and compared the relative importance among them. We found that an E
B-dominant filament has aligned fragmentation type, while E
G-dominant hubs show no and clustered fragmentation types. In the E
G dominant hubs, it seems that the portion of E
K determines whether the hub becomes to have clustered (the portion of E
K ∼ 20%) or no fragmentation type (∼10%). We propose an evolutionary scenario for the E- and W-HFSs, where the HFS forms first by the collision of turbulent flows, and then the hubs and filaments can go into various types of fragmentation depending on their energy balance of gravity, turbulence, and magnetic field.
Evidence of the Alfvén Transition Layer and Particle Precipitation in the Cusp Region: 3D Global PIC Simulation of the Solar Wind–Earth Magnetosphere Interaction
Authors: Lembège B. , Cai D. S. , Ekawati Sri 
Published: October 2022

Abstract
A transition layer, named the Alfvénic transition layer (or ATL), has been clearly evidenced near the outer boundary of the cusp by experimental observations from the Cluster mission. This layer characterized by a local value of Log M
A ∼ 1, where M
A is the Alfvén Mach number, allows the bulk flow to transit from super-Alfvénic to sub-Alfvénic from the exterior to the interior side of the outer cusp. The ATL has been observed during northward interplanetary magnetic field orientation, and mainly within the meridian plane. Currently, 3D Particle In Cell (PIC) global simulations of the solar wind–magnetosphere interaction are being performed in order to analyze the cusp region and this layer in detail. Present results stress the following points: (i) the ATL has a 3D structure; (ii) within the meridian plane, the ATL appears as a sublayer within a much more extended slow-mode pattern, and it is almost adjacent and located above the upper edge of the stagnant exterior cusp (SEC); and (iii) the plasma deceleration through the ATL is not uniform in the region located above the cusp. In addition, present preliminary results stress that (a) the spiraled streamlines of ion/electron fluxes converge when approaching the cusp, and their intensity strongly increases; and (b) ion and electron energetic fluxes penetrating the cusp region strongly differ in terms of their penetration depths and are issued from different regions of the magnetosphere/magnetosheath. Our results illustrate the importance of 3D effects used with a PIC simulation approach allowing the analysis of each population simultaneously.
Stars on the Verge: From Days to Decades, Studying the Photometric Variations of the Red Supergiant W Persei
Authors: Larsen Conor M. , Guinan Edward F. 
Published: October 2022

Abstract
W Persei is a massive, luminous and large red supergiant located relatively nearby. W Persei is a probable SN-II progenitor. We analyzed ∼120 yr of photometry from the AAVSO database. The analysis was conducted in the period analysis software Peranso where the CLEANest power spectrum and WWZ-wavelet programs were utilized. Two dominant periods of P = 532 ± 68 days and P = 2922 ± 140 days are found. Intermediate and transitory periods are also uncovered along with period events such as a significant increase in the long-period, period-merging and period-splitting. Using Transiting Exoplanet Survey Satellite observations, stochastic ∼0.3–0.8 mmag light variability on timescales of ∼0.3 day appears present. The physical causes of these variations is discussed.

Published: October 2022

Introduction: Despite the success which was achieved in the treatment of arterial hypertension, for optimization of the treatment, it is necessary to study the pathogenesis of primary arterial hypertension and target organ damage on the molecular level.
Materials and methods: Our team studied the molecular mechanisms of myocardial damage during arterial hypertension and metabolic disorders. We used the spontaneously hypertensive rats (SHR) as an experimental model, and, additionally, we modeled diabetes mellitus and atherosclerosis in these rats.
Results and discussion: Our study obtained evidence of a much higher level of the energy imbalance in the cardiomyocytes and more intensive production of reactive oxygen species in the SHRs with diabetes mellitus and atherosclerosis compared with the healthy animals and the animals with only hypertension. The indicated defections create an environment for further cellular damage – mitochondrial dysfunction, depletion in the thiol-disulfide system, and formation of highly reactive NO products. At the same time, we have noticed a higher activity of the Hsp70 in the hypertensive groups compared with the normotensive animals. The source of these deviations is in the formation of mitochondrial dysfunction of cardiocytes, the cause of which is oxidative modification of the protein structures of mitochondria under conditions of activation of oxidative stress reactions, insufficiency of mPT pores, and impaired mitochondrial chaperone function. The presented data give reason to believe that mitochondrial dysfunction, which develops against the background of deficient HSP70, is an integral aspect of arterial hypertension, contributes to its aggravation, and triggers a cascade of molecular and biochemical mechanisms of myocardial damage. These mechanisms include disturbances in the L-arginine-NO-synthase-NO system, production of mitochondrial iNOS oxygen radicals, neutralization of the vasorelaxant effect of NO and its transformation into an active participant in nitrous stress due to reduced intermediates of the thiol-disulfide system. The question of cause-and-effect relationships of oxidative stress remains open for discussion.
Conclusion: We envisage that studies in this direction may lead to a better insight into a pathogenetic therapy of essential hypertension, diabetes mellitus, and atherosclerosis.

Diagnostic Reasoning Outcomes in Nurse Practitioner Education: A Scoping Review
Authors: Griffith Patricia B. , Mariani Bette , Kelly Michelle M. 
Published: October 2022

Background:
Diagnostic reasoning is the process of collecting, considering, and analyzing information to determine a diagnosis. Educational strategies that structure diagnostic reasoning exposure, experience, and evaluation are hypothesized to improve diagnostic safety. However, few studies measure diagnostic reasoning outcomes in nurse practitioner education. This review sought to identify the educational interventions intended to improve diagnostic reasoning competency, determine which components of reasoning are evaluated, and examine how they are measured.

Method:
Four databases were searched, and 12 studies were identified that met the inclusion criteria.

Results:
Simulation was the most common intervention. The most frequently measured diagnostic reasoning components were information gathering, differential diagnosis, and leading diagnosis. Checklists and patient management problems were the most used assessment method.

Conclusion:

More studies are needed to assess the reasoning processes of hypothesis generation, problem representation, and diagnostic justification. Within simulation, methods capable of capturing these components include think-aloud, global assessments, checklists, and note evaluation.

Authors: Salian Sushmitha , D'Cunha Rithesh J. , Fernandes Shannon F. , Gurumurthy T. 
Published: October 2022

Background and aims:The ongoing Covid pandemic has burdened the medical system, more so due to the limited availability of ventilators. Our study aims at identifying the role of hematological markers in the risk stratification and the need for ventilator support among ICU admitted COVID-19 patients.
Methods: A single centre prospective study was conducted on 100 Covid positive patients admitted in the ICU to determine association between the haematological markers such asHb, Platelet count, Total and Differential leukocyte count, CRP, AST, ALT, LDH, Ferritin and D-Dimer with the need for oxygen therapy with or without invasive ventilatory support. Comparative analysis was performed between the 2 groups.
Results: Neutrophilia, a mean of 76.7% among those ventilated and 71.6% among those non ventilated (p value 0.002; highly significant) and Lymphocytopenia (p value 0.004) with a mean of 14% and 18.6% respectively was noted. Hemoglobin levels were lower in ventilated (mean 11.6g/dl) as against those non ventilated (mean 12.58%) p value 0.046 which was significant. D-dimer was increased in COVID-19 patients; mean 5380 ng/ml in ventilated patients and mean 949ng/ml in those non ventilated (P < 0.001 highly significant). Elevated D-dimer and presence of diabetes correlated with increased chances of mechanical ventilation, while higher hemoglobin levels and associated COPD have a negative association with the need of mechanical ventilation.
Conclusion: Hypercoagulability along with neutrophilia and lymphocytopenia can be used as positive associations for the need for invasive mechanical ventilation.
Sinus Bradycardia and Hypotension Following Reconstructive Hemi Mandibulectomy. Unusual Complication of Orofacial Reconstructive Surgery
Authors: Nagarajah Tharanitharan 
Published: October 2022

Postoperative complications following pectoralis major myocutaneous flap in orofacial reconstruction are a well-known entity. Still, literature search didn’t reveal sinus bradycardia as one of those post-operative complications. One of our patients, a 63-year-old gentleman with squamous cell carcinoma in the right cheek, who underwent wide local excision with right side hemi-mandibulectomy and pectoralis major myocutaneous flap reconstruction, developed symptomatic sinus bradycardia and hypotension as a postoperative complication. Initially there was a struggle to find out the underlying cause but later, carotid sinus hypersensitivity was suspected as a probable cause. Ultimately, it was alleviated by a debulking surgery to reduce the pressure in the neck.
Factors in and Barriers to Engagement and Service Within Athletic Training Association Leadership
Authors: Wise Stephanie L. , Payne Ellen K. 
Published: October 2022

Context
Leadership skills are important for all athletic trainers whether or not they hold formal leadership positions. Active engagement by members within professional associations can enhance individuals' leadership skills and aid the growth of the profession.

Objective
Understand common factors in and barriers to athletic trainers' involvement in leadership positions within their state's athletic training association.

Design
Qualitative – Grounded theory.

Setting
Zoom interview.

Patients or Other Participants
A purposeful sampling was performed. Inclusion criteria were met if participants were certified for 5+ years and currently serving on the executive board of their state athletic training association. Fifteen athletic trainers (age = 42.7 ± 7.8 years), predominantly men (73%), were included in this study. Data saturation guided the total number of participants selected.

Data Collection and Analysis
Semistructured interviews were performed using Zoom and transcribed verbatim. Data were analyzed using inductive content analysis. Transcripts were coded and grouped by themes and subthemes. To maintain trustworthiness, peer review and member checks were performed.

Results
Participants were primarily motivated to seek out leadership opportunities in their state association to get involved within the profession. They also received encouragement from influential individuals who helped the participants see their abilities to impact others. The main barrier participants identified was fear. Fear encompassed many aspects, including ambiguity surrounding their role, as they were unsure of their full responsibilities or how to perform the role successfully. Other barriers included time commitment and self-doubt.

Conclusions
Participants' desire to get involved and the encouragement they received helped to increase confidence in their abilities to lead and contributed to their involvement in their state association. By encouraging colleagues, coworkers, and mentees to get involved, as well as by athletic training associations implementing a transition period for newly elected leaders to learn their responsibilities, many barriers athletic trainers identified can be reduced.

Published: October 2022

Shea tree (Vitellaria paradoxa subsp. nilotica) is an important commercial tree for domestic oil and industrial products of cosmetics, chocolate and other confectionaries traded grown worldwide. We studied seed morphometric characteristics and crude oil content of Shea nuts in Uganda. Five populations, comprising of 16 ethnovarieties, were selected from Eastern, Northern and West Nile Sub-regions of Uganda, based on their attributes as judged by the farmers. Fresh kernel weight ranged from 2 to 18.85 mg per seed. Kernel weight increased with Shea fruit weight (y = 0.1499x + 6.1887, R² = 0.306). Moyo district had the highest oil content (54.37 ± 0.32%); while Amuru district had the lowest oil content (50.5 ± 1.32%). Oil content decreased with increasing kernel size (y = -0.4541x + 57.303, R² = 0.2116) and dry matter content (y = 0.635x - 9.863, R²= 0.011); and varied between ethnovarieties and Shea tree populations, p = 0.003 and P< 0.001, respectively. Tinny seeded (45.7 - 65.49%), Round fruited (45.41 - 65.91%), Dwarf tree (45.19 - 64.19%), Elliptical fruited (45.32 - 64.19%) and Soft pulped (42.16 - 69.77%) ethnovarieties had the highest oil content. Narrow sense heritability (h2) for oil yield was 1.72; while response to selection (R) was 16.48 with genetic gain (Gs) of 2.21%, given 10% top selection intensity.
