EPHA3 enhances macrophage autophagy and apoptosis by disrupting the mTOR signaling pathway in mice with endometriosis
Authors: Xu Hongmei , Gao Yongmei , Shu Yang , Wang Yi , Shi Qingyang
Published: July 2019

Background: Endometriosis is a chronic fibrotic disease characterized by agonizing pelvic pain and low fertility, mainly affecting middle-aged women. The aim of the present study is to assess the potential effects of erythropoietin-producing hepatocellular carcinoma A3 (EPHA3) on endometriosis, with emphasis on the autophagy and apoptosis of macrophages via inhibition of the mammalian target of rapamycin (mTOR) signaling pathway.

Methods: The mouse models of endometriosis were established followed by culturing the macrophages and macrophage transfection via the EPHA3 vector, siRNA EPHA3, and RAPA (an inhibitor of the mTOR signaling pathway). The expression of EPHA3, related factors in the mTOR signaling pathway, macrophage autophagy (autophagy-related gene 3 (Atg3), light chain 3-I (LC3-I), light chain 3-II (LC3-II) and Beclin1) and apoptosis (B-cell lymphoma-2 (bcl-2), bax and fas) were all detected and documented, respectively. The changes of autophagic lysosomes and the apoptosis of macrophages in each group following transfection were also inspected and detected.

Results: The results of the in silico analysis ascertained EPHA3 to be a candidate gene of endometriosis. After successful modeling, the uterine tissues of endometriosis mice presented with a low expression of EPHA3 and activated mTOR signaling pathway. Overexpression of EPHA3 inhibited the activation of the mTOR signaling pathway, down-regulated bcl-2 expression, up-regulated the expression of Atg3, LC3-II/LC3-I, Beclin1, bax and fas, and also promoted the autophagy and apoptosis of macrophages in endometriosis mice.

Conclusion: Altogether, EPHA3 could potentially promote the autophagy and apoptosis of macrophages in endometriosis via inhibition of the mTOR signaling pathway, highlighting the potential of EPHA3 as the target to treat endometriosis.
Dual-strand tumor suppressor miR-193b-3p and -5p inhibit malignant phenotypes of lung cancer by suppressing their common targets

Published: July 2019

Emerging studies suggest that microRNAs (miRNAs) play multiple roles in cancer malignancy, including proliferation and acquisition of metastatic potential. Differentially expressed miRNAs responsible for the malignancy of lung cancer were searched by miRNA microarray using a previously established brain metastatic lung cancer model. Twenty-five miRNAs were down-regulated in brain metastatic lung cancer cells. Among those, miR-193b-3p and -5p were chosen for further studies. Their function in metastatic potential and proliferation was examined using Transwell invasion, wound healing, and colony forming assays. The underlying mechanism of tumor-suppressor miR-193b-3p and -5p was explored using reverse transcriptase quantitative polymerase chain reaction (RT-qPCR), Western blot, Argonaute 2-RNA immunoprecipitation (Ago2-RIP), and reporter assays. Both strands of miR-193b were down-regulated in brain metastatic lung cancer cells and in tissues from lung cancer patients. Overexpression of miR-193b-3p and -5p inhibited invasive and migratory activities and diminished clonogenic ability. Conversely, inhibition of miR-193b-3p or -5p increased the metastatic potential and colony forming ability. Cyclin D1 (CCND1), Ajuba LIM Protein (AJUBA), and heart development protein with EGF like domains 1 (HEG1) were identified as common target genes of miR-193b-3p and -5p. A reporter assay and an Ago2-RIP experiment showed that both miRNAs directly bind to the 3′ untranslated region (3′UTR) of the target mRNA. Knockdown of target gene reduced the proliferative and metastatic potential of primary and metastatic lung cancer cells. Our results demonstrate miR-193b is a dual-strand tumor suppressor and a novel therapeutic target for lung cancer.

Published: July 2019

We retrospectively enrolled 825 breast cancer patients, who was primarily diagnosed in our hospital between January 2009 and December 2014 and explored the relationship between red blood cell distribution width (RDW) and long-term prognosis in patients with breast cancer. There were 412 patients with high RDW (RDW > 13.82) and 413 patients with low RDW (RDW ≤ 13.82). Compared with low RDW group, the high w group has large tumor size (the rate of tumor size >2 cm: 60.7 vs 44.8%, P=0.013). The rate of lymph node metastases was higher in the high RDW group thaten that in the low RDW group (62.1 vs 45.8%, P=0.000). RDW was positively associated with tumor stage. The high RDW tended to be advanced stage (P=0.000). Compared with low RDW group, the high RDW group tended to be higher lymphocyte count (P=0.004), elevated fibrinogen (P=0.043), and elevated high-sensitivity C-reactive protein (P=0.000). The Kaplan–Meier analysis indicated elevated RDW was positively associated with disease-free survival (DFS) (P=0.004) and overall survival (OS) (P=0.011). The multivariate Cox regression analysis indicated that the high RDW group had poorer OS (Hazard risk [HR] = 2.43; 95% CI: 1.62–3.21; P=0.024) and DFS (HR = 1.89; 95% CI: 1.28–3.62; P=0.000) compared with low RDW group. The present study found that high pretreatment RDW levels in breast cancer patients were associated with poor OS and DFS. RDW could be a potential predictive factor in differential diagnosis of poor prognosis from all patients.
Functional Anatomy Underlying Pharyngeal Swallowing Mechanics and Swallowing Performance Goals
Authors: Pearson William G. , Griffeth Jacline V. , Ennis Alexis M.
Published: July 2019

Purpose

Rehabilitation of pharyngeal swallowing dysfunction requires a thorough understanding of the functional anatomy underlying the performance goals of pharyngeal swallowing. These goals include the safe and efficient transfer of a bolus through the hypopharynx into the esophagus. Penetration or aspiration of a bolus threatens swallowing safety. Bolus residue indicates swallowing inefficiency. Several primary mechanics, or elements of the swallowing mechanism, underlie these performance goals, with some elements contributing to both goals. These primary mechanics include velopharyngeal port closure, hyoid movement, laryngeal elevation, pharyngeal shortening, tongue base retraction, and pharyngeal constriction. Each element of the swallowing mechanism is under neuromuscular control and is therefore, in principle, a potential target for rehabilitation. Secondary mechanics of pharyngeal swallowing, those movements dependent on primary mechanics, include opening the upper esophageal sphincter and epiglottic inversion.

Conclusion

Understanding the functional anatomy of pharyngeal swallowing underlying swallowing performance goals will facilitate anatomically informed critical thinking in the rehabilitation of pharyngeal swallowing dysfunction.

ALMA observations have revealed nuclear dusty molecular disks or tori with characteristic sizes 15−40 pc in the few Seyferts and low -luminosity AGN that have been studied so far. These structures are generally decoupled both morphologically and kinematically from the host galaxy disk. We present ALMA observations of the CO(2–1) and CO(3–2) molecular gas transitions and associated (sub-) millimeter continua of the nearby Seyfert 1.5 galaxy NGC 3227 with angular resolutions 0.085 − 0.21″ (7–15 pc). On large scales, the cold molecular gas shows circular motions as well as streaming motions on scales of a few hundred parsecs that are associated with a large-scale bar. We fit the nuclear ALMA 1.3 mm emission with an unresolved component and an extended component. The 850 μm emission shows at least two extended components, one along the major axis of the nuclear disk, and the other along the axis of the ionization cone. The molecular gas in the central region (1″ ∼ 73 pc) shows several CO clumps with complex kinematics that appears to be dominated by noncircular motions. While we cannot conclusively demonstrate the presence of a warped nuclear disk, we also detected noncircular motions along the kinematic minor axis. They reach line-of-sight velocities of v − vsys = 150 − 200 km s−1. Assuming that the radial motions are in the plane of the galaxy, we interpret them as a nuclear molecular outflow due to molecular gas in the host galaxy that is entrained by the AGN wind. We derive molecular outflow rates of 5 M⊙ yr−1 and 0.6 M⊙ yr−1 at projected distances of up to 30 pc to the northeast and southwest of the AGN, respectively. At the AGN location we estimate a mass in molecular gas of 5 × 105 M⊙ and an equivalent average column density N(H2) = 2 − 3 × 1023 cm−2 in the inner 15 pc. The nuclear CO(2–1) and CO(3–2) molecular gas and submillimeter continuum emission of NGC 3227 do not resemble the classical compact torus. Rather, these emissions extend for several tens of parsecs and appear connected with the circumnuclear ring in the host galaxy disk, as found in other local AGN.

Estimation of ionospheric delay of NavIC/IRNSS signals using the Taylor Series Expansion
Authors: Desai Mehul V. , Shah Shweta N.
Published: July 2019

The delay in Navigation with Indian Constellation (NavIC)/Indian Regional Navigation Satellite System (IRNSS) signals due to the ionosphere are decisive because it leads to significant changes in the positional accuracy of the system. In this paper, we try to estimate the ionospheric time delay (ionodelay) precisely using the local Taylor Series Expansion (TSE) algorithm for a single frequency NavIC/IRNSS system. The performance of the local TSE algorithm is examined by considering two cases. In case I, the TSE was validated under the influence of an intense geomagnetic storm (8 September 2017) by considering NavIC/IRNSS data from the Indian equatorial and Equatorial Ionization Anomaly (EIA) regions. In case II, based on the quiet and disturbed days data, the local TSE model was examined at different locations in the local area (<10 km) using two NavIC/IRNSS receivers (i.e. reference and rover). The results of ionodelay and positional accuracy (Three Dimensional Distance Root Mean Square [3DRMS], Circular Error Probability [CEP], and Spherical Error Probability [SEP]) of NavIC/IRNSS for both the cases indicates that the single frequency local TSE algorithm performs the same as the reference dual frequency model, where as the global eight coefficient Klobuchar and the regional Grid Ionospheric Vertical Error (GIVE) model behaves differently. Therefore, the single-frequency TSE model improves the performance of the NavIC/IRNSS receiver in the local area, and the mathematical coefficient computation and additional frequency hardware cost have been reduced, with the acceptance of a maximum 0.8 m of errors.
Suizid nach Entlassung aus psychiatrischen Einrichtungen
Authors: Lenz Bernd
Published: July 2019

Bezogen auf die Allgemeinbevölkerung stellen Suizide zwar seltene Ereignisse dar, das Risiko steigt jedoch mit einer psychiatrischen Erkrankung. Besonders hoch ist es in den ersten Monaten nach Entlassung aus einer stationären psychiatrischen Behandlung. Bisher konnte man keine ausreichend zufriedenstellenden Prädiktoren für solche Suizide identifizieren. Daher müssen sich Kliniker in der täglichen Routine zur Einschätzung des individuellen Suizidrisikos weitestgehend auf ihre Intuition verlassen. Breitere Evidenz dazu, welche Patientencharakteristika mit Suizid nach Entlassung aus psychiatrischen Einrichtungen zusammenhängen, ist eine wesentliche Voraussetzung zur Optimierung der individualisierten Suizidprävention im Rahmen der Entlassplanung.

Published: July 2019

Hintergrund Bei Patientinnen und Patienten mit amyotropher Lateralsklerose (ALS) kann es im Krankheitsverlauf zum Auftreten von Veränderungen im Verhalten und in der Kognition kommen. Ein Teil der Betroffenen entwickelt eine Frontotemporale Demenz. Für die pflegenden Angehörigen stellen diese Veränderungen eine zusätzliche Herausforderung dar.

Ziel der Arbeit Beschreibung der Auswirkungen von krankheitsbedingten Veränderungen in Kognition und Verhalten auf das emotionale Befinden der pflegenden Angehörigen und die genaue Erörterung der resultierenden Belastungen.

Methodik In der vorliegenden Arbeit wurde mittels verschiedener Suchbegriffe in diversen Datenbanken recherchiert. Im Ergebnisteil erfolgt die Synthese der eingeschlossenen zehn Studien zur Beantwortung des Forschungsinteresses. Die Diskussion umfasst die weitere Auseinandersetzung mit der Thematik unter Einbeziehung ergänzender Literatur.

Ergebnisse Veränderungen im Verhalten und in der Kognition können die Entstehung einer Angst- und Depressionssymptomatik bei pflegenden Angehörigen begünstigen. Des Weiteren verweisen die Ergebnisse der Studien auf einen Zusammenhang von Apathie, Enthemmung und exekutiven Dysfunktionen mit einem gesteigerten Belastungsempfinden bei pflegenden Angehörigen.

Schlussfolgerung Veränderungen im Verhalten und in der Kognition bei Patienten mit amyotropher Lateralsklerose wirken sich negativ auf das emotionale Befinden der pflegenden Angehörigen aus und tragen zu einem erhöhten Belastungsempfinden bei. Hinsichtlich dieser krankheitsbedingten Veränderungen bedarf es einer frühzeitigen und ausführlichen Aufklärung der Betroffenen.
Cucurbita pepo–Rhus aromatica–Humulus lupulus Combination Reduces Overactive Bladder Symptoms in Women – A Noninterventional Study
Authors: Gauruder-Burmester Annett , Heim Stefan , Patz Brigitte , Seibt Stephanie
Published: July 2019

This prospective, noninterventional, multicenter 12-wk study in women with overactive bladder investigated the effectiveness of Granu Fink femina, a herbal combination of seed oil from Uromedic pumpkin (cultivar of Cucurbita pepo), Rhus aromatica (fragrant sumach) bark extract, and Humulus lupulus (hop) cone extract in a clinical setting. Patients documented overactive bladder symptoms and quality of life using questionnaires as well as diaries recording day- and nighttime micturition frequencies, urine leakages during physical activity or at sneezing or coughing, and use of incontinence pads. The full analysis set included 117 women (age: 21 – 78 y). Urination frequency decreased significantly with improvement during daytime in 49, 71, and 77 (out of 99) patients and at night in 45, 63, and 70 (out of 100) patients after 1, 6, and 12 wk, respectively. The mean frequency of leakages and used pads decreased significantly from 0.9 leakages and 2.0 pads at baseline to 0.4 leakages and 1.4 pads after 12 wk. In all measured aspects of overactive bladder-related quality of life, (coping, concern, sleep, social), statistically significant improvement was reached after 1 wk, with further improvement at 6 and 12 wk. Ninety-nine percent of the physicians and 95.4% of the patients rated tolerability as “very good” or “good”. Treatment with Granu Fink femina progressively improved overactive bladder symptoms and related quality of life with significant improvements already after 1 wk. Based on these effects and the observed excellent tolerability profile, Granu Fink femina may be considered a valuable therapeutic option for overactive bladder.

Authors: Huang Zhenyu , Pu Benfang , Li Fusheng , Liu KaiZhang , Hua Chunhui , Li Changhua , Zhao Changyi , Li Jie , Li Xinyuan
Published: July 2019

Background Microvascular decompression (MVD) has been widely accepted as a definitive therapy for primary trigeminal neuralgia (TN). However, some patients may not experience relief of TN symptoms following surgery. In this study, the findings of redo MVD are discussed.

Methods Between 2015 and 2017, 205 patients with primary TN underwent MVD surgery in Shanghai Tongren Hospital. Among these patients, 187 had immediate complete relief of symptoms, 8 improved apparently, and 10 reported no symptom relief. Of the 10 patients without relief, 6 underwent reoperation within 5 days, 2 underwent reoperation 3 months after the first procedure, and 2 refused to undergo reoperation.

Results The symptoms of those patients who received reoperation disappeared immediately after the surgery. In the second operations, new conflict sites at the motor roots were found in five cases. The real offending vessels were the superior cerebellar artery (SCA) or branch of the SCA in seven cases and the petrosal vein in one case. The nerve was not decompressed completely in either of the two cases. At the 12-month follow-up, no recurrence was found. For the other two patients who did not have reoperation, their symptom persisted. Postoperative complications showed no significant differences between the first and second operations.

Conclusion Compression of the motor roots might be one of the causes of TN. Thorough exploration of both sensory and motor roots of the trigeminal nerve is essential to performing a successful MVD operation. Early reoperation for resistant TN after MVD does not increase the incidence of complications.
Cluster beams, nano-ripples, and bio applications
Authors: Toyoda Noriaki , Tilakaratne Buddhi , Saleem Iram , Chu Wei-Kan
Published: July 2019

Gas cluster ions are aggregates of weakly bonded gas atoms or molecules. Upon the impact of an energetic gas cluster ion, multiple collisions occur between the target atoms and the atoms in the cluster ion. These impact processes are completely different from those of a collision-cascade process induced by a single atomic or molecular (monomer) ion. Although the impact process of gas cluster ions is different, ripples similar to those formed by monomer ions are formed by gas cluster ion impacts at oblique incidence. In this review, ripple formation by gas cluster ions is discussed with respect to their formation mechanism, characteristics, and applications as biosensors.
Vector-valued weak Gabor dual frames on discrete periodic sets
Authors: Li Yun-Zhang , Zhao Jing
Published: July 2019

The notion of weak dual frames is a generalization of that of dual frames. Gabor analysis on discrete periodic sets has potential applications in signal processing. This paper addresses vector-valued weak Gabor dual frames on discrete periodic sets. We introduce the notions of its weak oblique Gabor dual, weak Gabor duals of types I and II for a Gabor system on a discrete periodic set. Using the Zak-transform matrix method, we characterize these three kinds of weak duals and their uniqueness. Finally, we give an explicit expression of a class of weak Gabor duals and provide some examples.
On the large N limit of Schwinger-Dyson equations of a rank-3 tensor field theory
Authors: Pascalie R. , Pérez-Sánchez C. I. , Tanasa A. , Wulkenhaar R.
Published: July 2019

We analyze in this paper the large N limit of the Schwinger-Dyson equations in a rank-3 tensor quantum field theory, which are derived with the help of Ward-Takahashi identities. In order to have a well-defined large N limit, appropriate scalings in powers of N for the various terms present in the action are explicitly found. A perturbative check of our results is done up to second order in the coupling constant.
Effect of hydrostatic pressure on the electron-phonon scattering in GaAs
Authors: Tandon Nandan , Ram-Mohan L. R. , Albrecht J. D.
Published: July 2019

Electron-phonon (e-ph) interaction in semiconductors is responsible for many phenomena such as electron mobility and hot electron thermalization, which are important to compute charge transport in semiconductors. In semiconductors, the application of hydrostatic pressure modifies the character of conduction band valleys, changing the effective mass of carriers, and, consequently, changing the carrier mobility. This, in turn, may limit electron transport in the semiconductor. Here, we present the effect of hydrostatic pressure on the e-ph interaction in GaAs, which goes from a direct to an indirect bandgap semiconductor at high pressures. A detailed study of e-ph self-energy and the resulting scattering rates is presented for hydrostatic pressure ranging between 0 and 9.2 GPa. Individual contributions from phonon modes to the total scattering rates indicate that short wavelength LO phonon scattering is found to be the dominant mechanism at low pressures; and at higher pressures, acoustic as well as optic phonons contribute toward the overall e-ph scattering. Finally, relaxation times are evaluated and we find that at pressures above 2.9 GPa, electron relaxation times are an order of magnitude lower than at equilibrium. These results will influence transport properties at higher pressures.
High-temperature neutron powder diffraction studies on atomic structure of (1−x)PbTiO3-xBi(Zn0.5Ti0.5)O3
Authors: Jeong I.-K. , Kim Bog-G.
Published: July 2019

The atomic structure of (1−x)PbTiO3-xBi(Zn0.5Ti0.5)O3 (x=0.1, 0.2, 0.25) is investigated across the tetragonal to cubic phase transition by neutron powder diffraction measurements up to temperature T=750°C. Both the long-range average structure and the local atomic distributions are studied from Rietveld refinements and atomic pair distribution function (PDF) analysis combined with reverse Monte-Carlo (RMC) modeling, respectively. In the tetragonal phase, the average structure is featured with a large shift of oxygen, which is responsible for an off-centering of cations. With increasing concentration x, the shift of the planar oxygen along the c-axis increases further. The increment of the oxygen displacement is larger than that of the Ti/Zn displacement. This makes the off-centering of cations larger at higher x, which enhances the stability of the tetragonal phase with higher transition temperature. On thermal displacements, the heaviest ion Pb/Bi in the structure exhibits the largest value and is also increased by the concentration x in both the tetragonal and cubic phases. The local structure from PDF and RMC modeling shows that the abnormal thermal displacements are due to a large distribution of Pb off-centering and a bond-length mismatch between Ti–O and Zn–O bonds. Based on these complementary local and average structures, a splitting between Ti and Zn displacements is discussed.
Absolute deflection measurements in a micro- and nano-electromechanical Fabry-Perot interferometry system
Authors: De Alba Roberto , Wallin Christopher B. , Holland Glenn , Krylov Slava , Ilic B. Robert
Published: July 2019

Fabry-Perot laser interferometry is a common laboratory technique used to interrogate resonant micro- and nano-electromechanical systems (MEMS/NEMS). This method uses the substrate beneath a vibrating MEMS/NEMS device as a static reference mirror, encoding relative device motion in the reflected laser power. In this work, we present a general approach for calibrating these optical systems based on measurements of large-amplitude motion that exceeds one half of the laser wavelength. Utilizing the intrinsic nonlinearity of the optical transduction, our method enables the direct measurement of the system’s transfer function (motion-to-detected-voltage). We experimentally demonstrate the use of this technique to measure vibration amplitudes and changes in the equilibrium position of a MEMS/NEMS device using monolithic silicon nitride and silicon cantilevers as sample systems. By scanning the laser along a cantilever surface, we spatially map static and dynamic deflection profiles simultaneously and then compare the static profile against results from a commercial optical profilometer. We further demonstrate the extension of our calibration technique to measurements taken at small amplitudes, where the optical transduction is linear, and to those taken in the frequency domain by a lock-in amplifier. Our aim is to present a robust calibration scheme that is independent of MEMS/NEMS materials and geometry, to completely negate the effects of nonlinear optical transduction, and to enable the assessment of excitation forces and MEMS/NEMS material properties through the accurate measurement of the MEMS/NEMS vibrational response.
On the choice of a conformal Gauss gauge near the cylinder representing spatial infinity
Authors: Paetz Tim-Torben
Published: July 2019

A convenient approach to analyze spatial infinity is to use a cylinder representation I and impose a gauge based on a congruence of conformal geodesics. This so-called conformal Gauss gauge comes along with the freedom to specify initial data for the conformal geodesics. Such a gauge has been constructed from an ordinary Cauchy surface and from past null infinity I −, respectively. The purpose of this note is to compare these gauges near the critical set I−, where I “touches” I −, as it turns out that they are related in a somewhat unexpected intricate way.

We systematically investigated the plasmon-polariton oscillations generated by a fast radiating charge (Cherenkov radiation) in a three-dimensional (3D) strongly disordered nanostructure. We studied the dynamic properties of an optical field in a random composition of empty single-wall nanotubes by using a 3D numerical finite-difference time domain technique. In our approach, only parameters of nanotube structures are fixed. The dynamic spectrum of internal field excitations was left to be defined as a result of numerical simulation. The patterns of total field (charge + carbon nanotubes) are determined by the interference of a moving charge field and the spectrum of surface plasmon-polaritons in disordered nanotubes. We found that the field energy losses, as a function of the charge velocity, has a clearly pronounced maximum when the characteristic frequency scale (defined by a charge velocity) is close to the frequency of the surface plasmon-polariton resonances generated in coupled nanotubes, even at a significant level of disorder. Our studies show that the shape of the resonance peak, depending on the charge velocity, is similar for carbon and TiO2 nanostructures, but, only for frequencies from the range of the surface plasmon polaritons of respective materials. The TiO2 nanostructure films for a classic cylindrical polytetrafluoroethylene cell was synthesized in our experiments too.

Transition metal dichalcogenide (TMDC) monolayers are promising materials for next-generation nanoscale optoelectronics, including high-speed light sources and detectors. However, most past reports on TMDC light-emitting diodes are limited to operation in high vacuum, while most applications require operation under ambient conditions. In this work, we study the time-resolved electroluminescence of monolayer WSe2 p-n junctions under ambient conditions and identify the decay in current over time as the main issue preventing stable device operation. We show that pulsed voltage bias overcomes this issue and results in bright electroluminescence under ambient conditions. This is achieved in a simple single-gate structure, without the use of dual gates, heterostructures, or doping methods. Internal quantum efficiency of electroluminescence reaches ∼1%, close to the photoluminescence quantum efficiency, indicating efficient exciton formation with injected carriers. Emission intensity is stable over hours of device operation. Finally, our device exhibits ∼15 ns rise and fall times, the fastest direct modulation speed reported for TMDC light-emitting diodes.

Pyrrole was polymerized and magnetized through a facile two-step method. Fe3+ acted as both an oxidant and a magnetic source in the reaction. The loss mechanism is discussed based on electromagnetic theory for different magnetized polypyrrole. It was found that the content of magnetic nanoparticles has a large influence on the absorption performance of the nanocomposite. This work might be an effective way to understand the balance between dielectric loss and magnetic loss in the practical application of electromagnetic wave absorption materials.

We have investigated the origin of the bandgap of BaMoO4, PbMoO4, and CdMoO4 crystals on the basis of optical absorption spectroscopy experiments and ab initio electronic band structure, density of states, and electronic localization function calculations under high pressure. Our study provides an accurate determination of the bandgaps Eg and their pressure derivatives dEg/dP for BaMoO4 (4.43 eV, −4.4 meV/GPa), PbMoO4 (3.45 eV, −53.8 meV/GPa), and CdMoO4 (3.71 eV, −3.3 meV/GPa). The absorption edges were fitted with the Urbach exponential model which we demonstrate to be the most appropriate for thick crystals with direct bandgaps. So far, the narrowing of the bandgap of distinct PbMoO4 had been qualitatively explained considering only the presence of the Pb 6s levels at the top of its valence band. Its fast pressure dependent redshift and the occurrence of its direct bandgap away from Γ in contrast to the other scheelites had remained unsolved. Here, we show that in contrast to what had been proposed and different from the other scheelites, in PbMoO4, the bandgap takes place between the Pb 6s levels at the top of the valence band and the antibonding O 2p levels at the bottom of the conduction band. For this reason, the direct bandgap is pushed away from the zone center in order to allow s–p mixing. Its pressure dependence is one order of magnitude faster than that in the other scheelites due to two effects: its delocalized character and the higher compressibility of dodecahedral units, PbO8, compared to tetrahedral units, MoO4.
Study of vacuum arc behavior under anode spot and anode plume modes

Anode spot (AS) and anode plume (AP) phenomena are widely observed in vacuum arc experiments and are related to anode melting and evaporation under strong heating from the arc column. Anode vapor will then strongly influence the arc column through ionization-recombination and energy exchange among atoms, ions, and electrons. This work investigated the characteristics of the vacuum arc with AS or AP using the two-dimensional magnetohydro dynamic model. Formation of the AS and AP modes was studied and analyzed using numerical simulation. Friction forces between ions and atoms were also taken into account. Simulation results show that anode vapor expansion depends on the pressure balance between the anode jet and cathode plasma. Higher anode temperature produces a larger neutral atom vapor area (NAVA), which was dominated by neutral atoms. Inside the NAVA, ion and electron temperatures were low in the AS and AP mode due to ionization and energy exchange. Electric conductivity in this area was also so low that the location of the maximal current density was near the edge of the anode instead of the anode center. The asymmetric appearance of an AP was mainly caused by the asymmetric anode temperature distribution with respect to the AS center. Qualitative comparisons show that the simulation results are consistent with the experimental results.

Contestation of Rhetoric within the Chinese Tradition: An Overview of Confucian Moralistic Rhetoric, Daoist Transcendental Rhetoric, and Mohist Utilitarian Rhetoric
Authors: Lu Xing
Published: July 2019

This paper reviews and compares diverse rhetorical conceptualizations within Chinese rhetorical tradition during the fifth to third century B.C.E. Textual evidence shows that three schools of thoughts, namely Confucianism, Daoism, and Mohism, have contested with and challenged one another on the components and functions of rhetoric. Confucianism is more concerned with the moral character of the speaker while Mohism claims that rhetoric is used for mutual benefit and contains a rational element. Daoism, on the other hand, approaches rhetoric with a transcendental and dialectical outlook. This overview demonstrates the multi-faceted characteristics of ancient Chinese rhetoric.
“Go Home, Purūravas”: Heterodox Rhetoric of a Late Rigvedic Dialogue Hymn
Authors: Thornton Elizabeth
Published: July 2019

This essay attempts to de-link the study of the Rigveda from both colonial philology and ongoing Hindu nationalist projects. It brings the rhetoric of form, especially as theorized by Kenneth Burke, to open up space for critics and commentators with a broader range of relationships to Brahmanical liturgy. To further the goal of delinking, it first narrows the scope of analysis to dialogue hymns, which are reminiscent of debates found within Buddhist conversion narratives rendered in versified Sanskrit. It then centers formal linguistic figures that these two layers of Sanskrit poetry have in common. Finally, conceptualizing these formal devices, it uses analytic categories from a South Asian critical tradition (alaṃkāraśāstra). Framed and constrained in this manner and applied to the (ex-)lovers’ quarrel of Purūravas and Urvaśī (in R.V. 10.95), a Burkean analysis reveals an exchange that both satisfies the “appetites” and allays the concerns of conservative audiences, who otherwise might fear that their wives could follow Urvaśī’s example and happily part with their wedded partners-in-sacrifice.

Coal Steam Power Plan is nowadays very important because it serves electricity in certain areas in Indonesia. Mpanau Coal Steam Power Plan (Mpanau PLTU) located at Palu (Central Sulawesi, Indonesia) which is a source of electricity for the people who live in Palu and its surrounding area. The energy source of PLTU derived from coal which is a fossil fuel. The use of coal as an energy source creates some environmental problems such as the ash waste (bottom ash and fly ash). Characterization of waste ash from fly ash and bottom ash in qualitatively and quantitatively ways is the first step to evaluate the environmental impacts related to environmental and biological contamination risk. In this research, silica concentration (SiO2) has been determined after separation method by extraction of both ashes from Mpanau PLTU. Silica concentration of bottom ash and fly ash sample was 21.31% and 29.85% respectively. Furthermore, the extraction silica was characterized by using Fourier Transmission Infra-Red (FTIR), X-Ray Diffraction (XRD), and Scanning Electronic Microscope (SEM) to see morphology.

The production of chitosanase enzyme was carried out by utilizing isolate of thermophilic bacteria from Bora hot spring in order to determine the optimum condition of its production process. B1211 bacterial isolates with the highest Chitinolytic Index values of 1.71 were used in crude chitosanase production. The crude chitosanase production was performed using a Completely Randomized Design (RAL) consisting of four independent variables, in the form of chitosan substrate concentration (0.25%, 0.50%, 0.75%, 1.00%), agitation speed (60, 90, 120, and 150 rpm), fermentation time (1, 3, 5, 7, and 9 days), and fermentation temperature (30, 40, 50, and 60°C). The activity of chitosanase as dependent variable was determined by Schales method, which referred to standard curve of D-glucosamine. The results showed that 1% chitosan substrate concentration yielded crude chitosanase with the highest activity of 0.408 U/mL and dissolved protein content of 9.887 mg/mL. Furthermore, the best agitation speed (90 rpm) resulted in 0.385 U/mL chitosanase activity and dissolved protein content of 23.74 mg/mL. In the fermentation time treatment, the 5-day fermentation time resulted in the highest chitosanase activity of 0.384 U/mL with dissolved protein content of 36.52 mg/mL. The fermentation temperature determination showed that the temperature of 60 °C as the preferred treatment with chitosanase activity of 0.569 U/mL and dissolved protein content of 5.752 mg/mL.

Published: July 2019

In previous research about analysis of slope stability on Lalingato Area, Tirawuta Districts, Kolaka Timur Regency, Sulawesi Tenggara, has been obtained slope instability with factor of safety between 0.38 - 0.64. This instability is caused by activity of geological structure, such as; joint. In the other hand, the effect of slope between 44 - 67 degrees are very influential. The study has conducted a theoretical investigation of the variation of slope form to minimize the landslide of slope. There were two schemes to investigate of slope stability as follows; (a) slope variation, and (b) slope terraces variation. The research has used Ms. Excel and Slide software. Based on the result of research was obtained that slopes with terraces will be easily stable. Meanwhile, if angle of the terraced slopes was given 35° - 44°, so factor of safety was 1.28 - 1.75. The future about the research will be developed to investigate slope stability with inhomogeneous material.
