Published: November 2019

Abstract
Compared with traditional materials, nanomaterial has rich and excellent performance due to the size advantages. If nanotechnology is combined with pavement materials, it is foreseeable that it will have a profound impact on the development of the road. In the study, graphene oxide nanomaterial was added as modifiers to rubber asphalt and its microstructure was characterized. The rheological properties of graphene oxide rubber asphalt and the road performance of asphalt mixture were studied in accordance with the SHRP test. The results showed that graphene oxide could form a dense and stable microstructure with rubber powder and asphalt polymer. As a modifier, it could improve the anti-rutting performance of rubber modified asphalt and was more suitable for heavy traffic. Moreover, it had low sensitivity to temperature and was more suitable for areas with large temperature difference between day and night. The pavement performance of the graphene oxide rubber asphalt mixture had also been greatly improved.

Abstract
The structural, mechanical and thermodynamic properties of tungsten-based alloys, including W0.5Ti0.5,W0.67Zr0.33,W0.666Ti0.1667Zr0.1667,W0.67Hf0.33 and W0.666Ti0.1667Hf0.1667, have been investigated in this paper by first-principles calculations based on density functional theory (DFT). The calculated elastic constants and mechanical stability criteria of cubic crystals indicated that all of these cubic alloys are mechanical stable. The mechanical properties, including bulk modulus (B), shear modulus (G), Young’s modulus(E), ratio B/G, Poisson’s ratio, Cauchy pressure and Vickers hardness are derived from the elastic constants Cij. According to calculated elastic modulus and Vickers hardness, the W0.666Ti0.1667Hf0.1667 alloy has the greatest mechanical strength. The Vickers hardness of these cubic alloys rank as follows: W0.666Ti0.1667Hf0.1667 > W0.67Zr0.33 > W0.666Ti0.1667Zr0.1667 > W0.5Ti0.5 > W0.67Hf0.33. Moreover, calculated ratio B/G, Poisson’s ratio, Cauchy pressure indicated that the ductility of W0.666Ti0.1667Hf0.1667 alloy is the worst among these alloys. The ductility of these cubic alloys rank as follows: W0.67Hf0.33 > W0.5 Ti0.5 > W0.67Zr0.33 > W0.666Ti0.1667Zr0.1667 > W0.666Ti0.1667Hf0.1667. What is noteworthy is that both mechanical strength and ductility of W0.666Ti0.1667Hf0.1667 are greater than pure W. Finally, Debye temperature, melting point and thermal conductivity have been predicted through empirical formulas. All these results will provide scientific data for the study on new product development of electrode materials.
Accounting for Variation in Language
Authors: Moravcsik Edith 
Published: November 2019

AbstractIn this paper, variation is defined as a type having more than one subtype. Using twelve examples from linguistics, two kinds of accounts are identified: eliminating variants and motivating them. Eliminating variants means a subtype is promoted to a type. Motivating variation in turn involves acknowledging the existence of the variants and explaining their existence either by reference to their differing meanings or by identifying the different contexts they occur in. The general applicability of these two ways of dealing with variation is shown by examples from other fields of study and from everyday life.
Musik und Moral: Intertextuelle Bezüge zwischen Lact.inst.6,21 und Sen.epist.123,9 f.
Authors: Speyer Kathrin 
Published: November 2019

AbstractThe goal of this article is to use structural, lexical and content analysis to make the case that the Church Father Lactantius, when composingDivinae institutiones6,21, engaged with Sen.epist.123,9 f. and pointedly refers to it. In the process, this whole chapter of Lactantius will be examined to see what the relation is between the decisive influence of the Seneca passage and that of other pre-texts that have already been identified as such in existing publications, especially the works of other Church Fathers. The content under discussion concerns the risks of purely instrumental music compared to those of artistically designed speech for the spirit of the listener, closely linked to the question of whether Christian writings, too, may – or even should – be aesthetically appealing. The treatment of this question leads ultimately to a general discussion of the relation of pleasure to virtue in the sense of a life pleasing to God.

Published: November 2019

Abstract
Silicon carbide coating is widely used in various industrial fields and plays an important role in protecting carbon fiber composite materials. Meanwhile, coating thickness is directly related to the performances of the functional coating and the substrate. Therefore, accurate coating thickness inspection and substrate property research are extremely valuable. Based on eddy current testing, this study investigated the effects of homogeneous electromagnetic properties and anisotropic conductivities on the performance of carbon fiber composite with different coating thicknesses. This investigation was conducted by simulating a three-dimensional finite element model of carbon fiber substrate–silicon carbide coating by ANSYS. Results showed that under homogenous conductivity of carbon fiber composite, the voltage values of the detection coil array were symmetrical about the axis of the excitation coil. Therefore, this property avoids detecting the repeatability of measurement data and shorts processing time to improve detection efficiency. Simultaneously, the change in mutual resistance exhibited a positive correlation with increased coating thickness. This trend was similar to that of the self-resistance of the excitation coil in anisotropic conductivity. Furthermore, the self-resistances of the excitation coil in anisotropy and the coating thickness meet a formula. Furthermore, supposing the carbon fiber composite material was in the x-axis direction, the electromagnetic signal was exactly opposite to the y-axis direction perpendicular to the x-axis.
Smart Scheduling of a Batch Manufacturer’s Operations by Utilization of a Genetic Algorithm to Minimize Electrical Demand
Authors: Brimley Paige , Machalek Derek , Powell Kody M. 
Published: November 2019

Abstract
Power utilities currently manage unpredictable electrical demand through the use of fast-ramping plants and punitive demand fees. Unpredictable demand makes it more difficult to onboard variable renewable energy sources, such as solar and wind, because of their intermittency, which can contribute to grid instability. Optimal utilization of variable renewable energy sources requires a flexible, resilient electrical grid and thus a transformation of the current system to a proposed “smart grid” that would adapt in real time to grid signals. Batch manufacturers are well suited to reduce the burden of intermittency by considering demand side management techniques when scheduling process operations. The goal of such participation is a reduction in electrical demand and associated costs for both the facility and the utility. This study investigates how a novel application of the genetic algorithm could be used to schedule a batch manufacturer’s operations in a manner that reduces overall peak demand and is compatible with process constraints. The genetic algorithm is chosen because it is highly efficient at finding minima and handling complex constraints and large data sets. A major highlight of this article is the use of measured demand profiles to log real-time energy consumption of process equipment. The scenarios investigated use a genetic algorithm to determine the optimum scheduling when given a fixed set of interdependent operations that must be executed within the day. All investigated scenarios have a reduction in peak demand after rescheduling via the genetic algorithm. Baseline operations demonstrated reductions between 13 % and 28 %, with an average reduction of 21 %. The results of this study demonstrate that automated load shifting can easily be applied to an industrial facility and paves the way for future work to investigate the integration of scheduling algorithms with process control systems.

Authors: Garré Saulo De Oliveira , Weymar Guilherme Jahnecke 
Published: November 2019

O propósito central deste trabalho foi desenvolver um sistema de interação com o usuário que gerasse a redução do tempo de cálculo de áreas durante o desenvolvimento de mapas topográficos. Para tanto, programou-se uma comunicação entre AutoCAD Map 3D®, ArcGIS® e Excel® (versão para estudantes e educadores), a qual possibilitou a troca de informações necessárias para a geração automática da planilha de cálculo. Para avaliar o desempenho da solução apresentada, fez-se um comparativo entre o Método Tradicional e o Método Automatizado. Nestes, para a geração do mapa, o operador separa as áreas (Campo Nativo, Estrada, Área Úmida, Campo Limpo, entre outras) em polígonos individuais que são exportados para o ArcGIS o qual efetua o cálculo da área de cada polígono e informa os valores obtidos. Estes resultados são posteriormente inseridos manualmente (Método Tradicional) ou automaticamente (Método Automatizado) na planilha de cálculos do AutoCAD Map 3D. Nesta análise, feita por meio de cronometragem, concluiu-se que o Método Automatizado reduziu em 67% o tempo de cálculo. Espera-se um percentual de redução no tempo de cálculo ainda maior, quando o operador trabalhar com mapas topográficos de alta complexidade, uma vez que estes necessitam de maiores detalhamentos e apresentam diversificações de características. Descreve-se todo o procedimento com o intuito de que a solução abordada possa ser utilizada em problemas distintos.
Synaptic Inhibition of Medial Olivocochlear Efferent Neurons by Neurons of the Medial Nucleus of the Trapezoid Body
Authors: Torres Cadenas Lester , Fischl Matthew J. , Weisz Catherine J.C. 
Published: November 2019

Medial olivocochlear (MOC) efferent neurons in the brainstem comprise the final stage of descending control of the mammalian peripheral auditory system through axon projections to the cochlea. MOC activity adjusts cochlear gain and frequency tuning, and protects the ear from acoustic trauma. The neuronal pathways that activate and modulate the MOC somata in the brainstem to drive these cochlear effects are poorly understood. Evidence suggests that MOC neurons are primarily excited by sound stimuli in a three-neuron activation loop from the auditory nerve via an intermediate neuron in the cochlear nucleus. Anatomical studies suggest that MOC neurons receive diverse synaptic inputs, but the functional effect of additional synaptic influences on MOC neuron responses is unknown. Here we use patch-clamp electrophysiological recordings from identified MOC neurons in brainstem slices from mice of either sex to demonstrate that in addition to excitatory glutamatergic synapses, MOC neurons receive inhibitory GABAergic and glycinergic synaptic inputs. These synapses are activated by electrical stimulation of axons near the medial nucleus of the trapezoid body (MNTB). Focal glutamate uncaging confirms MNTB neurons as a source of inhibitory synapses onto MOC neurons. MNTB neurons inhibit MOC action potentials, but this effect depresses with repeat activation. This work identifies a new pathway of connectivity between brainstem auditory neurons and indicates that MOC neurons are both excited and inhibited by sound stimuli received at the same ear. The pathway depression suggests that the effect of MNTB inhibition of MOC neurons diminishes over the course of a sustained sound.SIGNIFICANCE STATEMENTMedial olivocochlear (MOC) neurons are the final stage of descending control of the mammalian auditory system and exert influence on cochlear mechanics to modulate perception of acoustic stimuli. The brainstem pathways that drive MOC function are poorly understood. Here we show for the first time that MOC neurons are inhibited by neurons of the MNTB, which may suppress the effects of MOC activity on the cochlea.

VOLATILE COMPOSITION, ANTIOXIDANT PROPERTY AND ANTIMICROBIAL ACTIVITIES AGAINST FOOD-BORNE BACTERIA OF VIETNAMESE THYME (Thymus vulgaris L.) ESSENTIAL OIL
Authors: Quynh Cung Thi To , Trang Vu Thu 
Published: November 2019

The essential oil (EO) obtained from the leaves of the thyme (Thymus vulgaris L.) grown in Vietnam was found to contain thymol (39.79%), cymene (17.33%), and γ-terpinene (13.45%) as the main volatile components. The antimicrobial activities of this oil were screened against several food-borne bacteria and fungi species. Significant growth inhibition effects against food-borne bacteria Escherichia coli, Staphylococcus aureus, Bacillus cereus, and Salmonella Typhimurium were observed using the standard disc diffusion method. Thyme EO showed the antibacterial effect against all the test pathogenic strains with the inhibition zones were 23.3 ± 0.4 mm, 24.7 ± 0.4 mm, 29.0 ± 0.7 mm, 32 ± 0.7 mm in diameter against B. subtilis, E. coli, S. Typhimurium and S. aureus, respectively. The minimum inhibitory concentration (MIC) determined by micro-dilution method in MHB liquid medium was 1.56 µl/ml. The bactericidal concentrations (MBC) was 3.13 µl/ml for three isolates from B. subtilis, E. coli, and S. aureus, while the MBC tested for S. typhi was 1.56 µl/ml. The antifungal properties of the thyme EO were also determined in this study against three important pathogenic fungi such as Candida albicans, Rhizoctonia solani and Fusarium oxysporum with the inhibition zones ranging approximately from 23.20 ± 0.06 to 44.10 ± 0.03 mm. On the other hands, the results also showed the antioxidant activity of Vietnamese thyme EO and suggested that thyme EO can be applied in food industries as natural flavoring preservatives/additives to control food spoilage and food born bacteria and fungi.

Published: November 2019

Amaç: İskemik kalp hastalığına bağlı
gelişen mitral yetmezlik, halen operatif mortalitesi yüksek
seyirli bir hastalıktır. Cerrahi prosedür olarak halen bir fikir birliği
sağlanmamıştır. Bu çalışmada
İskemik Mitral Yetmezlikte (İMY), mitral kapak replasmanı (MVR) ve tamir sonuçlarının
karşılaştırılarak, birbirlerine üstünlüklerini ortaya koymak amaçlanmıştır.

Materyal ve Metod: 2007
ve 2011 yılları arasında Türkiye Yüksek İhtisas Eğitim ve Araştırma Hastanesi’nde,
İMY nedeniyle opere edilen 36 hasta incelenmiştir. Hastaların (38.9%) kadın, 22’si
(61.1%) erkekti. 20 hastaya MVR, 16 hastaya mitral rekonstrüksiyon yapıldı. Her
iki

grupta bütün vakalarda
koroner bypass mevcuttu. Hastalarda preoperatif risk faktörleri, mitral yetersizliğin
derecesi, sol ventrikül ejeksiyon fraksiyonları, pre-postoperatif fonksiyonel
klasifikasyonları, aort kros klemp ve kardiyopulmoner bypass süreleri, yoğun bakım ve hastane kalış
süreleri belirlendi. Bulgular: MVR yapılan grupta
preoperatif diyastolik çap ve kontrol diyastolik çap arasında anlamlı
olarak fark saptanmıştır (p=0.016). Bu grupta diyastolik çaptaki düzelme tamir grubuna
göre istatistiksel olarak daha iyi çıkmıştır. Ayrıca preoperatif fonksiyonel
kapasite

(FK)
ve kontrol FK arasında, düzelme yönünde anlamlı fark bulunmuştur (p=0.008).
Erken dönem
mortalite görülen hastalar incelendiğinde MVR yapılan grupta 6 hasta, tamir grubunda
5 hasta exitus oldu. Mortalite görülen 11 hasta ile sağ kalan hastalar
preoperatif ejeksiyon
fraksiyonu (EF) yönünden karşılaştırıldığında anlamlı bir fark bulunmamıştır. (p=0.986)

Sonuç: İMY‘de
öncelikle mitral tamir önerilse de, son zamanlarda bazı çalışmalarda da önerildiği
gibi, MVR yapılması mitral yetmezliğin tam giderilmesini sağlayıp, reoperasyon riskini
azaltmaktadır.
