Stability of the Sitnikov's circular restricted three body problem when the primaries are oblate spheroid

Field: Physics and Astronomy (Physical Sciences)

The Sitnikov's problem is a special case of restricted three body problem if the primaries are of equal masses (m1 = m2 = 1/2) moving in circular orbits under Newtonian force of attraction and the third body of mass m3 moves along the line perpendicular to plane of motion of primaries. Here oblate spheroid primaries are taken. The solution of the Sitnikov's circular restricted three body problem has been checked when the primaries are oblate spheroid. We observed that solution is depended on oblate parameter A of the primaries and independent variable τ = ηt. For this the stability of non-trivial solutions with the characteristic equation is studied. The general equation of motion of the infinitesimal mass under mutual gravitational field of two oblate primaries are seen at equilibrium points. Then the stability of infinitesimal third body m3 has been calculated. DOI: http://dx.doi.org/10.3126/bibechana.v11i0.10395 BIBECHANA 11(1) (2014) 149-156
Labour with epidural analgesia: Second thoughts about the second stage

Field: Medicine (Health Sciences)

SummaryThe effect on maternal and neonatal outcome of flexible guidelines for the management of the second stage of labour in uncomplicated primigravid term labours receiving epidural analgesia was examined in 327 consecutive confinements. With flexible guidelines, the second stage was allowed to proceed for an average of 44 minutes longer before it was felt that operative delivery was indicated for this reason alone. The total instrumental delivery rate after epidural analgesia decreased from 54 to 43 per cent (P < 0·05) and the proportion of mid-cavity forceps for ‘delay’ was reduced (P < 0·05). No change was found in maternal morbidity, measured by the frequency of haemorrhage, infection or bladder complications. The frequency with which active neonatal resuscitation was required seemed to be reduced; no relationship between umbilical cord venous pH and the duration of either active or passive second stages was found. A total second stage of up to 4 hours, consisting of 2·5 hours passive and up to 1·5 hours active labour, appears to be safe and offers an acceptable chance of normal delivery in this selected group.

Analysis of the steady double-front detonation structure for a detonable gas, laden with aluminium particles

Field: Engineering (Physical Sciences)

Under certain experimental conditions quasi-steady double-front detonations (DFD) have been observed to propagate in a shock tube filled with a two-phase mixture of a detonable gas with aluminum particles in suspension. The paper describes a quantitative numerical model for studying the DFD structure. It is based on the theory of two-phase flows in one-dimensional configuration with energy losses to the walls, and on an empirical burning law of aluminum particles. First computations performed for hydrogen-air mixtures with aluminum particles show that steady DFD may exist for (1) an appropriate range of mass concentration of particles and ( 2) a sufficient amount of energy losses to the walls. Reasonable agreement with experimental data is obtained. 18 references.
A comparative study of the epidemiology of Treponemal Infection in the Volta Region of Ghana: A Five-Year Multisite Parallel Population-Based Analysis vis-à-vis the Sentinel Survey

Field: Medicine (Health Sciences)

Abstract Abstract Background: Treponemal infection is contagious and one of the oldest blood-borne infections, with great public health consequences. This study aimed to comparatively describe the five–year (2013-2017) regional epidemiology of Treponemal infection using pregnant women in the Sentinel Survey and apparently healthy blood donors as proxy for the general population at the four sentinel sites in the Volta Region of Ghana. Method: We analysed retrospectively data from 17,744 prospective blood donors aged between 18 to 58 years and 7,805 pregnant women in a Sentinel Survey who fell within the 15 and 49 years age bracket at Hohoe, Ho, Tongu and Krachi-West sentinel sites in the Volta Region. Data extracted included age, gender, date of blood donation and Treponena pallidum chromatographic immunoassay results from the blood banks of the four study sites. Published reports of Sentinel Surveys conducted at the four sentinel sites from the years 2013-2017 were retrieved. Results: The cumulative five-year prevalence of Treponemal infections among the pregnant women in the Sentinel Survey and prospective blood donors was 0.38% and 2.38% respectively. Site-specific prevalence for population-base/Sentinel survey was 4.6%/0.4%, 2.0%/0.2%, 1.3%/0.8 and 1.2%/0.2 for Hohoe, Ho, Krachi-West and Tongu respectively. Treponemal infection rates among the younger age groups (15-24years) were 0.31% in the sentinel survey and 2.22% in the general population. Significant gender disparity in Treponemal infection exist with male preponderance. Conclusion: The regional prevalence of Treponemal infection in the Sentinel Survey is lower compared to the general population. Therefore, the use of pregnant women as proxy for population estimate could lead to underestimation of the burden in the study jurisdiction.
Analysis and construction of a competitive endogenous RNA regulatory network of baicalin-induced apoptosis in human osteosarcoma cells

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract Background: Baicalin is an extract from the traditional Chinese herb Scutellaria baicalensis . Recent literature reports have shown the potential of baicalin to treat osteosarcoma (OS). However, the transcriptome-level mechanism of baicalin-mediated antitumor effects in OS has not yet been investigated. The aim of this study was to analyze the competitive endogenous RNA (ceRNA) regulatory network involved in baicalin-induced apoptosis of OS cells. Methods: In this study, CCK-8 and flow cytometry assays were used to detect the antitumor effects of baicalin on human OS MG63 cells. Furthermore, whole transcriptome sequencing was employed to establish the long noncoding RNA (lncRNA), microRNA (miRNA), and mRNA profiles. Results: Baicalin could inhibit MG63 cell proliferation and could induce apoptosis. A total of 58 lncRNAs, 31 miRNAs, and 2136 mRNAs in the baicalin-treated MG63 cells were identified as differentially expressed RNAs compared to those in control cells. Of those, 2 lncRNAs, 3 miRNAs, and 18 mRNAs were included in the ceRNA regulatory network. The differentially expressed RNAs were confirmed by using quantitative real-time PCR (qRT-PCR). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed to identify the target genes and signaling pathways of the aberrantly expressed RNAs. Conclusions: By identifying the ceRNA network, our results provide new information about the possible molecular basis of baicalin, which might be able to be used for OS treatment.
Interprofessional Education in a Department of Urology

Field: Health Professions (Health Sciences)

Optimum health care delivery requires increasing reliance allied health care professionals who are members of highly functioning teams. However, few allied health care professionals are trained in the specific field of urology. Within our urology department, care of patients is fragmented into different segments with little to no crossover of staff. Patient care may benefit from specialty training and additional education sessions for those involved in patient care. Interprofessional Education (IPE) offers a potential way to improve collaboration and may enhance healthcare outcomes.
John Duns Scotus, Franciscan theologian philosopher, a thinker for our times: in place of a biography

Field: Arts and Humanities (Social Sciences)

An overview of the life and intellectual legacy of the Franciscan theologian-philosopher John Duns Scotus (died 1308), sometimes called Scotland's greatest philosopher, draws on the most recent historical scholarship and treatments of his thought. From his origins in Duns, Scotland, to his influential tenure in Paris and death in Cologne, Scotus's life is considered alongside his important doctrines: the univocity of being, which reshapes metaphysical discourse, and the Immaculate Conception of Mary, a cornerstone of his theological impact. This discussion clarifies the context and significance of the ‘charge of heresy’ sometimes linked to Scotus, and considers modern engagements with Scotus's thought – both positive and critical – which point to his enduring relevance.
An evaluation of the new highly sensitive hemagglutination method for assaying urinary hCG and LH.

Field: Medicine (Health Sciences)

A clinical evaluation of an anti-human chorionic gonadotropin (HCG)-antibody sensitized hamagglutination (HAR) method was performed on urinary specimens collected daily from patients with hydatidiform mole and from females with normal menstrual cycles and results compared with a simultaneously performed radioimmunoassay. Results were also compared with assays by the hemagglutination inhibition reaction (HAIR) for monitoring trophoblastic disease. The sensitivity of the HAR technique was 5 IU/L for hCG and 12.5 mIU/ml for luteinizing hormone (LH). The correlation coefficient of hCG specimens collected from patients with hydatidiform moles was r = .93 and that of LH specimens from normally menstruating females r = .74. The sensitivity of HAIR is approximately 500-1000 IU/L. Radioimmunoassay always gave higher results than HAR. However the chief advantages of this method are its rapidity simplicity and a sensitivity nearly equal to radioimmunoassay without use of radioactivity.
Influence of Concentrated Solar Power on Plasma Sprayed Hybrid Thermal Barrier Coatings

Field: Materials Science (Physical Sciences)

Abstract The multi-layered thermal barrier coatings (TBC) are commonly used in the systems exposed to extensive heat, such as jet engines or gas turbines. The testing of coatings' performance is usually carried out using electric or gas furnace. Concentrated solar power (CSP) could provide cost-effective and environmentally friendly alternative using natural energy source. Moreover, it can also simulate materials exposure in real applications, e.g., in solar power-plants. In this study, possibility of using concentrated solar power to test the performance of hybrid YSZ-based TBCs prepared by hybrid water/argon-stabilized plasma (WSP-H) technology was studied for the first time. In service, TBC top-coat layer may be exposed also to so-called CMAS air-borne particles occurring in the atmosphere which may melt at elevated temperatures and penetrate the coating microstructure, inducing crystallographic and volumetric changes therein. Therefore, testing with the presence of CMAS particles was also included in this study to observe its influence on the coating microstructure under solar irradiation. Changes of the coating microstructures were studied using SEM analysis and X-ray diffraction.
Modelling Smoke Flow Using Computational Fluid Dynamics

Field: Engineering (Physical Sciences)

There have been a number of experimental investigations into the backdraft phenomena. A backdraft occurs in the event of a ventilation source being formed in a compartment, within which a fire has been burning for a sufficiently long enough time to form a deep layer of excess pyrolyzates. The source of fresh air will flow into the compartment in the form of a gravity current. It is the gravity current feature of backdrafts that this research project focuses on. Application of Computational Fluid Dynamics (CFD) to fire problems is expanding, including the development of specific programs for fire engineering applications. The experimental programme that was used in this research project highlights the difficulties of analysing fluid flows by using CFD simulations. The Flow3D program was used to obtain a more detailed understanding of the behaviour of a gravity current, allowing a detailed study of fluid dynamics which cannot be investigated experimentally. The simulations used two different vent configurations, with the CFD model being validated on the experimental results of salt water tank models. The simulations preformed compared well to the experimental data that was used for scaled salt water tank experiments.
The Effects of Kinesio Taping and Kettlebell Training on Shoulder Isokinetic Muscle Strength and Pitching Speed of Amateur Baseball Players

Field: Health Professions (Health Sciences)

OBJECTIVES The purpose of this study was to investigate the effects of 6 weeks of kettlebell training and kinesio taping applied to amateur baseball players on throwing velocity and isokinetic strength.METHODS The subjects of this study were 17 young men with more than 2 years of experience as amateur baseball players. To determine the effect of kettlebell training and kinesio training on throwing velocity and isokinetic strength, subject were divided into three group: kettlebell and kinesio taping, baseball training group (KTBG), kinesio taping group and baseball training (TBG), baseball training group (BG). Three groups trained three times a week for six weeks, and differences in shoulder isokinetic strength and throwing velocity were analyzes from pre to post training.RESULTS In the KTBG group, significant changes in the isokinetic muscle function of the shoulder joint were observed over time in both extensor strength (p=0.042) and flexor strength (p=0.017) at 60°/sec, as well as in extensor strength (p=0.028) and flexor strength (p=0.002) at 180°/sec. In the TBG group, only flexor strength at 180°/sec (p=0.020) showed significant changes. In the BG group, no significant changes were observed over time. The group interaction effect on isokinetic muscle function was not statistically significant. There were no significant changes in pitching velocity over time, and no group interaction was observed.CONCLUSIONS Therefore, a combination of 6 weeks of kettlebell training and Kinesio taping can improve the isokinetic extensor and flexor strength of the shoulder joint. Applying Kinesio taping during training can enhance the isokinetic extensor strength (180°/sec) of the shoulder joint. However, this exercise did not result in an increase in pitching velocity, and no interaction effect was observed, indicating the need for further research.
Evidence for the role of osteocytes in the initiation of targeted remodeling

Field: Medicine (Health Sciences)

Microdamage in bone contributes to fractures and acts as a stimulus for bone remodeling. Osteocytes are the most abundant cells in bone, and their death by microdamage has been suggested to be the major event leading in the initiation of osteoclastic bone resorption. Even though there is increasing evidence that osteocyte density, microcracks and targeted remodeling are related, there still exist several questions. For example, how osteoclasts are targeted to the specific site of microdamage for repair. It has been proposed that apoptotic osteocytes could secrete a specific signal to target osteoclasts. The other question is the nature of this signal. To elucidate the role of microdamage-induced osteocyte cell death in the initiation of targeted remodelling, this paper discusses the potential use of an in vitro model, in which osteocytes can be three-dimensionally cultured and locally damaged. Furthermore, the method enables one to study the osteocyte-derived soluble interactions with bone marrow cells. It was demonstrated that damaged osteocytes locally affect osteoclast precursors by secreting osteoclastogenic factors, and thus can have a role in the initiation of resorption in bone remodelling. This strongly supports the idea that damage to osteocyte cellular network has the potential to stimulate osteoclastic proliferation and therefore the activation of Basic Multicellular Units (BMUs).

Field: Medicine (Health Sciences)

Abstract Funding Acknowledgements Type of funding sources: Public hospital(s). Main funding source(s): Hospital Universitari Vall d"Hebron - Vall d"Hebron Institut de Recerca. CIBERCV BACKGROUND Patients with structural heart disease (SHD) or bundle branch block (BBB) are at high risk of having an arrhythmic syncope (AS). In patients with recurrent syncope episodes (RSE) complete work-up including electrophysiological study (EPS) and/or implantation of a loop recorder (ILR) is recommended, however patients with their first episode may also be at risk of an AS. AIM To determinate if the patients with SHD or BBB with a single syncope episode (SSE) are at high risk of having an AS and compare it with patients with recurrent episodes (RSE). METHODS Cohort study carried out in a tertiary hospital that is a reference centre for syncope. From January 2008 to August 2020 patients with SHD or BBB with syncope of unknown origin after the initial evaluation and without direct indication of an ICD were included. They were managed according the current ESC guidelines. RESULTS 417patients were included (74 ±11 y. o; 39% female). Mean follow up was 2.5 ±1 y. 223 patients were diagnosed from an AS [113 (53%) in SSE group and 110 (54%) in RSE group, p = 0.9], 210 were due to bradyarrhythmia (AV block or sinus arrest). No differences in baseline characteristics where found comparing both groups, except that BBB was slightly more prevalent in patients with RSE (81% vs 90%, p = 0.01) (FIGURE- PANEL A). Risk of AS was 53% in patients with SE and 54% (p = 0.9). RSE were not associated with an increased risk of AS in univariate analyses (OR 1.01 IC95% 0.7-1.5) neither in the multivariate (FIGURE- PANEL B). EPS and ILR diagnostic yield was 45% / 32% respectively in SSE group and 44% / 33% in RSE group (p = 0.8) (FIGURE - PANEL C). After appropriate treatment, recurrence syncope rate was 10% in SSE group and 9% in RSE group (p = 0.8). No significant differences in mortality rate were found. CONCLUSIONS Patients with SHD or BBB and single syncope episode are at a high risk of having AS, and similar to those with RSE. EPS and ILR offer a similar diagnostic yield in both groups. Complete syncope work-up must be recommended in these patients despite having had only a single episode. Abstract Figure
Heated Infrared Sample Cell for Volatile Fluorides

Field: Chemistry (Physical Sciences)

Routine reaction rate comparison studies of highly corrosive gaseous fluorides, such as CIF3 and F2, extending to temperatures above 100°C required the development of an improved heated ir gas cell. The cell features cooled window gaskets composed of Teflon, all nickel construction, and a tapered sample space to reduce the internal volume. The internal temperature of the cell can be accurately determined and controlled by the use of parameter design charts to set the control variables. The cell, which has proven to be reliable and easy to operate for the intended service, has also been extended to applications requiring vaporizing air sensitive compounds onto the cooled windows for direct ir observation.
Indoor Localization and Mapping: Towards Tracking Resilience Through a Multi-SLAM Approach

Field: Computer Science (Physical Sciences)

This paper presents a use case for SLAM techniques applied to real time localization and detailed mapping for emergency response personnel in non cooperative environments. Such environments tend to defeat conventional localization approaches, therefore we must ensure continuous operation of our localization and mapping regardless of the difficulties encountered (lack of GPS signals, lighting conditions, smoke, etc.). The proposed system fuses two SLAM algorithms, a LiDAR-based and a camera-based. Since LiDAR-based SLAM uses dense 3D measurements, it is well suited to the construction of a detailed map, while the visual SLAM allows to quickly recognize already visited places in order to apply loop closure corrections, by using a key frames graph. The currently proposed system allows collaboration between these two SLAMs through pose sharing and relocalization.
Tracking the paths of residual conductance during leaf expansion in Tilia americana and Fagus grandifolia

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract The rate of residual water loss is a major determinant of plant survival during drought, yet how the major paths of residual water flow develop as leaves expand is poorly understood. Here, we tracked the rate of residual water loss, the compositional development of cuticular wax, stomatal differentiation, pore formation, and xylem development as leaves expand in two co-occurring, deciduous tree species Tilia americana and Fagus grandifolia. As leaves expanded, residual conductance declined rapidly, primarily driven by decreases in cuticular conductance, which was the main pathway for residual water loss from branches with young leaves. Very little water was lost through stomatal pores as leaves expanded, because the outer cuticular ledge only formed above the majority of stomata once leaves approached complete expansion. Similar development of residual conductance was observed between the two species despite differences in cuticle composition and stomatal development timing as leaves expanded. Our work suggests that the cuticle is the primary pathway through which water is lost from the youngest expanding leaves, and residual conductance is minimized only when cuticular wax deposition is complete, stomata have formed, and leaves have fully expanded.
