Treatment Recommendations for Adults with Various Stages of Heart Failure
Authors: Lee Stephanie , Stern Craig
Published: August 2020

Heart failure (HF) is a progressive disease state resulting from disorders of the pericardium, myocardium, endocardium, heart valves or from certain metabolic diseases. Heart failure is the preferred term over congestive heart failure, since not every patient presents with fluid overload. Patients with heart failure will often have symptoms of left ventricular (LV) myocardium dysfunction. HF patients can have a wide range of LV functions leading to various ejection fraction (EF).

Published: August 2020

The aim of the study: Combined use of kineso- and laser therapy to correct regional hemodynamic disorders in patients with dilated cardiomyopathy (DCMP).
Material and methods: The study included 100 patients diagnosed with DCMP. The diagnosis "DCMP" was established for patients with dilatation of the heart cavity of non-coronatural origin, increased heart size (final diastolic size of the left ventricle - LV CDR > 6.0 cm). The determination of the CHF FC was made according to the Russian National Recommendations of the RSCS (2018) and OSSN on the diagnosis and treatment of CHF. All patients took differentiated medication-assisted therapy according to indications during 3 months. Patients were divided into 2 comparable groups by sex, age, disease course, severity of the condition, and specifics of medication therapy. Patients of the 1st group were treated with intravenous laser irradiation of blood (ILIB) and selection of unloading therapeutic gymnastics against the background of supporting differentiated medication therapy. Patients of the 2nd group (control) received only differentiated medication therapy. The main method of investigation was venous occlusal plethysmography to evaluate regional hemodynamics with the determination of blood flow (Qr) and regional vascular resistance (Rr) at rest, venous tone (Vt), reserve blood flow (QH) and regional vascular resistance (RH) on the background of a functional load test.
РResults: The data obtained during the dynamic observation (in 1, 3, 6 and 12 months) in the main group showed a reliable increase in the volume velocity of the blood flow at rest (Qr) and the reserve blood flow (QH), a decrease in the regional vascular resistance at rest (Rr) and under functional load (RH), venous tone (Vt), respectively. In the control group there was no reliable positive dynamics, after 12 months of observation indicators of regional hemodynamics significantly deteriorated.
Conclusion: In patients with DCMP, according to venous occlusal plethysmography, the use of relieving therapeutic gymnastics in combination with ILIB on the background of medication therapy has significantly improved the indices of regional hemodynamics. The developed method of non-drug therapy can be used by cardiologists, general practitioners, therapists, doctors of physical and rehabilitation medicine to optimize treatment of patients with DCMP.

Flood is a common natural disaster, especially in Indonesia, and causes a huge amount of material and social loss. West Sumatera is one of the provinces that is often affected by flooding, and one of the most affected area is Solok Selatan District. In this district, there is a junction of two watersheds that often affected by floods, which are Batang Suliti watershed and Batang Bangko watershed. The junction of the Batang Suliti river and Batang Bangko river is in Sungai Pagu Sub-District. One example of a huge flood occurred on February 8, 2016 where the rain occurred for 17 hours long which caused a 0.5–3 m deep of flood inundation and covering 11.9 km2 area. Hence, it is necessary to know how much is the capacity of the river’s cross-sections to accommodate the water flow before runoff discharge occurs. In this study, we calculate the runoff discharge using HEC-RAS 4.0 software and Q25 discharge which are 332.42 m3 /s for the Batang Suliti river and 336.43 m3 /s for the Batang Bangko river.

Dynamics of the Parker–Jeans Instability of Gaseous Disks Including the Effect of Cosmic Rays
Authors: Kuwabara Takuhito , Ko Chung-Ming
Published: August 2020

The effect of cosmic rays on the Parker–Jeans instability in magnetized self-gravitating gaseous disks is studied using three-dimensional magnetohydrodynamic simulations with cosmic rays taken as a massless fluid with notable pressure. Cosmic-ray diffusion along the magnetic field is taken into account in the simulation. The initial configuration of the disk is a magnetized cold gas slab sandwiched between hot coronae (on top and bottom). We show that cosmic rays play an important role in the formation of filaments or clumps in some parameter regimes. In a certain range of the thickness of the gas slab, the cosmic-ray diffusion coefficient plays a decisive role in determining whether the filaments lie along or perpendicular to the magnetic field. We also consider the effect of rotation on the system.
Testing the Cosmic Opacity at Higher Redshifts: Implication from Quasars with Available UV and X-Ray Observations

Published: August 2020

In this paper, we present a cosmological model-independent test for the cosmic opacity at high redshifts (z ∼ 5). We achieve this with the opacity-dependent luminosity distances derived from the nonlinear relation between X-ray and UV emissions of quasars, combined with two types of opacity-independent luminosity distances derived from the Hubble parameter measurements and simulated gravitational wave (GW) events achievable with the Einstein Telescope (ET). In the framework of two phenomenological parameterizations adopted to describe cosmic opacity at high redshifts, our main results show that a transparent universe is supported by the current observational data at a 2σ confidence level. However, the derived value of the cosmic opacity is slightly sensitive to the parameterization of τ(z), which highlights the importance of choosing a reliable parameterization to describe the optical depth τ(z) in the early universe. Compared with previous works, the combination of the quasar data and the H(z)/GW observations in similar redshift ranges provides a novel way to confirm a transparent universe (ϵ = 0 at higher redshifts z ∼ 5), with an accuracy of Δϵ ∼ 10−2. More importantly, our findings indicate that a strong degeneracy between the cosmic-opacity parameter and the parameters characterizing the L

A Black Hole Feedback Valve in Massive Galaxies

Published: August 2020

Star formation in the universe’s most massive galaxies proceeds furiously early in time but then nearly ceases. Plenty of hot gas remains available but does not cool and condense into star-forming clouds. Active galactic nuclei (AGNs) release enough energy to inhibit cooling of the hot gas, but energetic arguments alone do not explain why quenching of star formation is most effective in high-mass galaxies. In fact, optical observations show that quenching is more closely related to a galaxy’s central stellar velocity dispersion (σ

v
) than to any other characteristic. Here we show that high σ

v
is critical to quenching because a deep central potential well maximizes the efficacy of AGN feedback. In order to remain quenched, a galaxy must continually sweep out the gas ejected from its aging stars. Supernova heating can accomplish this task as long as the AGN sufficiently reduces the gas pressure of the surrounding circumgalactic medium (CGM). We find that CGM pressure acts as the control knob on a valve that regulates AGN feedback and suggest that feedback power self-adjusts so that it suffices to lift the CGM out of the galaxy’s potential well. Supernova heating then drives a galactic outflow that remains homogeneous if

. The AGN feedback can effectively quench galaxies with a comparable velocity dispersion, but feedback in galaxies with a much lower velocity dispersion tends to result in convective circulation and accumulation of multiphase gas within the galaxy.
Astrophysical Distance Scale. II. Application of the JAGB Method: A Nearby Galaxy Sample
Authors: Freedman Wendy L. , Madore Barry F.
Published: August 2020

We apply the near-infrared J-region asymptotic giant branch (JAGB) method, recently introduced by Madore & Freedman, to measure the distances to 14 nearby galaxies out to 4 Mpc. We use the geometric detached eclipsing binary (DEB) distances to the LMC and SMC as independent zero-point calibrators. We find excellent agreement with previously published distances based on the tip of the red giant branch (TRGB): the JAGB distance determinations (including the LMC and SMC) agree in the mean to within

 mag, just over 1%, where the TRGB I-band zero-point is M

I
 = −4.05 mag. With further development and testing, the JAGB method has the potential to provide an independent calibration of Type Ia supernovae, especially with the James Webb Space Telescope. The JAGB stars (with M

J
 = −6.20 mag) can be detected farther than the fainter TRGB stars, allowing greater numbers of calibrating galaxies for the determination of H
0. Along with the TRGB and Cepheids, JAGB stars are amenable to theoretical understanding and further refined empirical calibration. A preliminary test shows little dependence, if any, of the JAGB magnitude on metallicity of the parent galaxy. These early results suggest that the JAGB method has considerable promise for providing high-precision distances to galaxies in the local universe that are independent of distances derived from the Leavitt Law and/or the TRGB method, and it has numerous and demonstrable advantages over the possible use of Mira variables.
Tidal Currents Detected in Kraken Mare Straits from Cassini VIMS Sun Glitter Observations
Authors: Heslar Michael F. , Barnes Jason W. , Soderblom Jason M. , Seignovert Benoît , Dhingra Rajani D. , Sotin Christophe
Published: August 2020

We present Cassini Visual and Infrared Mapping Spectrometer (VIMS) observations of sun glitter—wave-induced reflections from a liquid surface offset from a specular point—on Kraken Mare. Sun glitter reveals rough sea surfaces around Kraken Mare, namely the coasts and narrow straits. The sun glitter observations indicate wave activity driven by the winds and tidal currents in Kraken Mare during northern summer. T104 Cassini VIMS observations show three sun glitter features in Bayta Fretum indicative of variegated wave fields. We cannot uniquely determine one source for the coastal Bayta waves, but we lean toward the interpretation of surface winds, because tidal currents should be too weak to generate capillary–gravity waves in Bayta Fretum. T105 and T110 observations reveal wave fields in the straits of Seldon Fretum, Lulworth Sinus, and Tunu Sinus that likely originate from the constriction of tidal currents. Coastlines of Bermoothes and Hufaidh Insulae adjoin rough sea surfaces, suggesting a complex interplay of wind-roughened seas and localized tidal currents. Bermoothes and Hufaidh Insulae may share characteristics of either the Torres Strait off Australia or the Åland region of Finland, summarized as an island-dense strait with shallow bathymetry that hosts complex surface circulation patterns. Hufaidh Insulae could host seafloor bedforms formed by tidal currents with an abundant sediment supply, similar to the Torres Strait. The coastlines of Hufaidh and Bermoothes Insulae likely host ria or flooded coastal inlets, suggesting that the Insulae may be local peaks of primordial crust isolated by an episode of sea-level rise or tectonic uplift.

Tuning the mechanical properties and degradation properties of polydioxanone isothermal annealing
Authors: LIU Xiliang , FENG Shaomin , WANG Xin , QI Jin , LEI Dong , LI Yadong , BAI Wei
Published: August 2020

Polydioxanone (PPDO) is synthesized by ring-opening polymerization of p-dioxanone, using stannous octoate as the catalyst. The polarized optical micrograph (POM) shows thes pherulite growth rate of PPDO decreases with an increase in the isothermal crystallization temperature. PPDO is compression-molded into bars, and PPDO bars are subjected to isothermal annealing at a range of temperatures (Ta = 50, 60, 70, 80, 90, and 100 °C), and correspond to three different annealing times (ta = 1h, 2h, 3h). The effect on PPDO is investigated by using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and scanning electron microscopy (SEM). With an increase in Ta and ta, the grain size and the degree of crystallinity also increase. Meanwhile, the tensile strength is significantly improved. The PPDO bars (90 °C, 2 h) reach the maximum crystallinity (57.21%) and the maximum tensile strength (41.1 MPa). Interestingly, the heat treatment process does not result in serious thermal degradation. It is observed that the hydrolytic degradation of the annealed PPDO is delayed to some extent. Thus, annealed PPDO might have potential applications, particularly in the fields of orthopedic fixation and tissue engineering.

Published: August 2020

Entre mise à l’agenda par le haut et mobilisation localisée des acteurs, la territorialisation de la question climatique s’appuie sur des ressources cognitives et institutionnelles différenciées entre régions françaises. La mise en politique par des élus principalement écologistes et les prémisses d’une action publique territorialisée constituent des vecteurs d’appropriation d’un enjeu construit initialement comme problème scientifique. Ces facteurs participent à relativiser la centralisation et standardisation des politiques imbriquées de l’énergie et du climat.

CARA-OHT: Collision-Aware Rate Adaptation for Optimal High-Throughput in IEEE 802.11s Wireless Mesh Networks
Authors: Arif Teuku Yuliar , Munandar Munandar , Adriman Ramzi , Munadi Rizal
Published: August 2020

The wireless mesh network (WMN) is a future network technology that develops single-hop wireless local area networks (WLANs) into multi-hop wireless mesh networks, based on the IEEE 802.11s standard. However, this development still presents many challenges, such as determining the best route between sources and destinations, especially taking into account the use of the medium access control (MAC) and physical (PHY) layers of IEEE 802.11n/ac. Some papers have proposed rate adaptation algorithms particularly for single-hop networks; however, these only focused on mechanisms to find data rates suitable for channel conditions. In IEEE 802.11s WMNs, the design of the rate adaptation algorithm is more challenging. Besides considering the problem of channel quality and optimal throughput, it is necessary to also consider the problem of collision and the best route. It is important to take collision into account because the collision probability in multi-hop mesh networks is higher than that in single-hop networks and can lead to a lower throughput. Rate adaptation algorithms for IEEE 802.11s WMNs have been proposed in other papers, but they also do not consider the use of the MAC and PHY layers of IEEE 802.11n/ac. In this paper, we propose the collision-aware rate adaptation for optimal high-throughput (CARA-OHT) algorithm for WMN IEEE 802.11s. An evaluation through the extensive use of a network NS-3 simulator shows that the proposed algorithm exhibits a higher throughput than previously developed algorithms.

The objective of this study was to analyze the sociodemographic, clinical and therapeutic profile of psychiatric hospitalizations related to mental and behavioral disorders. This is an analytical cross-sectional study conducted in a hospital reference in psychiatric treatment in Teresina, Piauí, Brazil. The data were collected with the aid of a form to characterize the sociodemographic, clinical and therapeutic aspects of hospitalizations. The SPSS version 22.0 was used. There was analysis of 291 medical records of patients admitted during the period from February to May 2018, which revealed the year 2018 with the highest rate of psychiatric hospitalization, 239 (82.1%). There was prevalence of men 184 (63.2%), unmarried 209 (71.8%), with a mean age of 38.4 years. There was also a predominance of patients with low schooling. The sex was statistically associated with the use of illicit drugs (p:0.003), suicide attempts (p:0.04) and type of admission (p:0.006). On the other hand, schooling was associated with abandonment (p:0.008); suicide attempt (p:0.033) and previous hospitalizations (p:0.006). Many factors and comorbidities increase the possibility of the patient re- hospitalization.

Luffa operculata is a medicinal plant widely used in the treatment of rhinosinusitis in Brazil. The aim of this work was to carry out a preliminary analysis of the antioxidant and antimicrobial profile of Luffa operculata extracts. The antioxidant activity of the commercial solution, hydroalcoholic extract, infusion and ethanolic extract obtained from the commercialized fruit were evaluated for 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS•+) and 2,2-Diphenyl-1-picrylhydrazyl (DPPH•) radicals. The antimicrobial activity was determined by minimum inhibitory concentration against the pathogens Staphylococcus aureus, Escherichia coli and Candida albicans. It was shown that the hydroalcoholic extract exhibited the highest antioxidant and antimicrobial activity when compared to the aqueous and ethanolic extracts by the methods employed on this work. Thus, the extracts of Luffa operculata are a good source of active principles with pharmacological activity.

Rutin is a flavonoid used in clinical practice to treat capillary fragility and prevent bleeding due to its wide variety of pharmacological actions, including antioxidant, anti-inflammatory, anti-allergic, antiproliferative, and anticarcinogenic activities. In this study, the biopharmacotechnical and physical properties of film-coated tablets containing rutin marketed in drugstores were evaluated. Using samples from three batches called A, B and C, we determined the average weight, disintegration time, hardness, content and dissolution profile, and kinetics of the tablets. The samples demonstrated average weight of 457.45 ± 12.32 to 449.15 ± 8.95 mg; disintegration time, 30.17 ± 2.14 to 15.17 ± 2.14 min; hardness, 1.92 ± 0.55 to 1.69 ± 0.36 Kgf; and rutin content, 18.34 ± 1.21 to 15.66 ± 1.29 mg. After 90 min, the dissolution profile showed 52.65, 41.80, and 79.2% for A, B, and C, respectively. The results imply that the non-conformities of the tested products can significantly compromise the drug’s therapeutic efficacy.

Equine-assisted therapy uses the horse in rehabilitation and/or education of people, such as Down syndrome (SD), cerebral palsy (PC) and intellectual disability (DI). In context, the rehabilitation program and horse riding equipment should be used according to the specific characteristics of each individual, becoming an ally in the quest for excellence in equine-assisted therapy programs. The aim was to evaluate the effect of riding equipment used in equine-assisted therapy on the muscular activity of trunk and lower limb of individuals with SD, PC and DI. The study included 15 individuals equally assigned to each group: SD, PC and DI with a mean age of 16.2 (± 1.10), 16 (± 1.22) e 16 (±0) years, respectively. The analysis of muscle activity was performed through surface electromyography, using four variations of horse riding equipment: saddle with and without feet supported on the stirrups and blanket with and without feet supported on the stirrups. Sigma Stat 3.5® software was used for statistical analysis. The Shapiro Wilk’s test was used for normality of the data, the Bartlett test for homogeneity of the variances and the Kruskal-Wallis test for repeated measures with no normal distribution. Statistically significant differences were observed for p < 0.05. The SD group presented a greater muscular activity of trunk and lower limbs with blanket equipment without the feet supported in the stirrups (H = 15.078, p = 0.002), as in the DI group (H = 8.302, p = 0.040), while in PC group was the saddle with feet supported in the stirrups (H = 11.137, p = 0.011). The choice of riding equipment used in equine-assisted therapy interferes differently in the pattern of muscular activation of the trunk and the lower limbs, according to the pathological processes of the practitioners. It should be an important aspect to consider when planning a treatment.

Published: August 2020

The ability of superabsorbent polymers (SAP) to absorb water vapor was studied. A multilayer composite material was prepared where SAP particles were spread in the fluffy fibrous layer located in the middle of the composite structure. Distribution of SAP within the composite material permits air to pass through its porous structure effectively hence allowing efficient contact of air with SAP. SAP was able to decrease the relative humidity of air of a 3-L cabinet from 96% relative humidity (RH) to 52% and 49 % (RH) in 18 hours using 2 g and 4 g of SAP respectively. Study on the water vapor absorption ability of SAP placed together with pure water in a closed cabinet was conducted with and without convective air transport effect. Convective air transport was done by activating the 12 V fan allowing air recirculation speed at rates corresponding to constant voltage settings of 6 V and 12 V. Higher SAP water vapor absorption rate was obtained at higher air recirculation speed. SAP particles swelled after water vapor absorption with slight decrease in the porosity of composite material as observed through the digital microscope.
Microwave Absorbance of Double-Layer Laminates of Glass Fiber Composite Containing Carbon Black and Carbon Fiber Composite
Authors: Kim Sung Soo
Published: August 2020

The microwave absorbing properties of multi-layer carbon/carbon fiber composites, designed to function as radar absorbing structures (RAS), were studied over the X-band frequency range (8.0-12.4 GHz). High-frequency electromagnetic properties of various fibers (glass, carbon) and particulate filler (carbon black) are investigated as the major constituent materials of the RAS. Free space measurement depicts the perfect reflecting properties of carbon fiber composites (S11 = 0 dB, S21 = −40 dB). In the two-layered composite laminate (impedance transformer/reflecting substrate), the use of carbon black is necessary in the impedance transforming layer to obtain the high level of microwave absorbance and frequency tuning. Through the layer combination of the glass-fiber composite (thickness = 2.45 mm) containing carbon black (3% in weight) and carbon fiber composite as reflecting substrate, S11 can be reduced to as low as −40 dB at the frequency of 11.7 GHz, maintaining a low level of S21. The results demonstrate that RAS can be efficiently designed with the laminates of fiber reinforced composites with impedance transforming layer (glass fiber with suitable amount of carbon black) and perfectly reflecting substrate (carbon fiber).

Geopolymer concrete was presented to produce alternative binder to cement. This study considered the influence of silica fume on the properties of metakaolin based geopolymer mortar exposed to high temperature up to 800 °C. Five mortar mixes were used with silica fume replacing level of 0, 10, 20, 30 and 40% of weight of metakaolin. The results demonstrated that the compressive and splitting tensile strength increased with increasing the silica fume replacing level up to 40% of weight of metakaolin for all burning temperature and the absorption was decreased with it. The outcomes also demonstrated that for the same mix the compressive and splitting tensile strength improved with increment burning temperature up to 400 °C and reduced with increasing the temperature above it until 800 °C.

Due to urbanization, the use of concrete in construction and waste production are arising that resulted to negative impact in environment. There are several studies utilizing cementitious material as substitute to cement and plastic waste as additive to concrete which has potential in increasing the strength. This study utilized recycled polypropylene macro fiber (RPPMF) as a reinforcement and rice hull ash (RHA) as substitute to cement. Varying percentage of RHA (10%, 15%, and 20%) and RPPMF (0.5%, 0.75%, and 1.0%) were incorporated in the concrete mix. Compressive and flexural strength results showed that the combination of RHA and RPPMF has a significant effect in the strength of concrete. Based from the results, the concrete with 10% replacement of RHA and 0.5% addition of RPPMF is theoptimum which has the highest compressive strength of 19.47 MPa with an increase of 13.40%, and a maximum flexural strength test of 3.7 MPa with an increase of 18.62%. Furthermore, the concrete with 10% replacement of RHA for both with additive of 0.75% and 1% RPPMF also attained higher flexural strength than of normal mix with 18.07% and 3.45% increase, respectively. It can be recommended to use for basement foundation walls and slabs, walks, patios, steps, and stairs. Also, it can be used for street roads because it reaches the standard strength of normal mix concrete and lessen the cracks due to addition of RPPMF.
