Published: October 2019

Background: Pulmonary vein isolation (PVI) is a routine treatment in atrial fibrillation (AF). Single-shot techniques were introduced to simplify the procedure. We analyzed time-dependent changes in procedural parameters, acute success, complication rates, and long-term outcomes during our initial experience with multipolar phased-radiofrequency (RF) ablation. Methods and Results: The first 126 consecutive patients (98 male; age: 58.8 ± 8.7 years) who underwent PVI with phased-RF ablation at our center were included in the study. Procedural parameters, complication rate, acute success and 12-month efficacy were compared in the first, second and third group of 42 consecutive patients. In all patients, 516/526 PVs were effectively isolated (98.1%), with no differences between the tierces (p = 0.67). Procedure (169.8 vs. 132.9 vs. 105.8 min, p < 0.0001), fluoroscopy (32.9 vs. 24.3 vs. 14.1 min, p < 0.0001) and left atrial dwell (83.0 vs. 61.9 vs. 51.4 min, p < 0.0001) times were significantly reduced with experience in tierces 1–3, respectively. In the 12-month follow-up, 60.3% of patients were arrhythmia-free with no differences between the tierces (p = 0.88). In multivariate analysis, the relapse in the blanking period (p < 0.0001), time from AF diagnosis (p = 0.004) and left atrial diameter (p = 0.012) were the only independent predictors of AF recurrence. Conclusions: The learning curve effect was demonstrated in procedural parameters, but not in the complication rate nor the long-term success of PVI with phased-RF technique. The relapse in the blanking period was the strongest predictor of treatment failure in long-time observation.

Published: October 2019

Various multilayered thin films are extensively used as the basic component of some micro-electro-mechanical systems, requiring an efficient measurement method for material parameters, such as Young’s modulus, residual stress, etc. This paper developed a novel measurement method to extract the Young’s moduli and residual stresses for individual layers in multilayered thin films, based on the first resonance frequency measurements of both cantilever beams and doubly-clamped beams. The fabrication process of the test structure, the corresponding modeling and the material parameter extraction process are introduced. To verify this method, the test structures with gold/polysilicon bilayer beams are fabricated and tested. The obtained Young’s moduli of polysilicon films are from 151.38 GPa to 154.93 GPa, and the obtained Young’s moduli of gold films are from 70.72 GPa to 75.34 GPa. The obtained residual stresses of polysilicon films are from −14.86 MPa to −13.11 MPa (compressive stress), and the obtained residual stresses of gold films are from 16.27 to 23.95 MPa (tensile stress). The extracted parameters are within the reasonable ranges, compared with the available results or the results obtained by other test methods.
Zirconocene-Catalyzed Dimerization of α-Olefins: DFT Modeling of the Zr-Al Binuclear Reaction Mechanism
Authors: Nifant’ev Ilya , Vinogradov Alexander , Vinogradov Alexey , Karchevsky Stanislav , Ivchenko Pavel
Published: October 2019

Zirconocene-mediated selective dimerization of α-olefins usually occurs when precatalyst (η5-C5H5)2ZrCl2 is activated by minimal excess of methylalumoxane (MAO). In this paper, we present the results of density functional theory (DFT) simulation of the initiation, propagation, and termination stages of dimerization and oligomerization of propylene within the framework of Zr-Al binuclear mechanism at M-06x/DGDZVP level of theory. The results of the analysis of the reaction profiles allow to explain experimental facts such as oligomerization of α-olefins at high MAO/(η5-C5H5)2ZrCl2 ratios and increase of the selectivity of dimerization in the presence of R2AlCl. The results of DFT simulations confirm the crucial role of the presence of chloride in the selectivity of dimerization. The molecular hydrogen was found in silico and proven experimentally as an effective agent that increases the rate and selectivity of dimerization.

Published: October 2019

To evaluate the effects of phenol formaldehyde (PF) resin modification on wood cell walls, Masson pine (Pinus massoniana Lamb.) wood was impregnated with PF resin at the concentrations of 15%, 20%, 25%, and 30%, respectively. The penetration degree of PF resin into wood tracheids was quantitatively determined using confocal laser scanning microscopy (CLSM). The micromechanical properties of the control and PF-modified wood cell walls were then analyzed by the method of quasi-static nanoindentation and dynamic modulus mapping techniques. Results indicated that PF resin with low molecular weight can penetrate deeply into the wood tissues and even into the cell walls. However, the penetration degree decreased accompanying with the increase of penetration depth in wood. Both the quasi-static and dynamic mechanics of wood cell walls increased significantly after modification by the PF resin at the concentration less than 20%. The cell-wall mechanics maintained stable and even decreased as the resin concentration was increased above 20%, resulting from the increasing bulking effects such as the decreased crystallinity degree of cellulose. Furthermore, the mechanics of cell walls in the inner layer was lower than that in the outer layer of PF-modified wood.

Age-related strength and muscle mass loss is further increased after acute periods of inactivity. To avoid this, resistance training has been proposed as an effective countermeasure, but the additional effect of a protein supplement is not so clear. The aim of this study was to examine the effect of a whey protein supplement enriched with leucine after resistance training on muscle mass and strength gains in a post-hospitalized elderly population. A total of 28 participants were included and allocated to either protein supplementation or placebo supplementation following resistance training for 12 weeks (2 days/week). Physical function (lower and upper body strength, aerobic capacity and the Short Physical Performance Battery (SPPB) test), mini nutritional assessment (MNA) and body composition (Dual X-ray Absorptiometry) were assessed at baseline and after 12 weeks of resistance training. Both groups showed improvements in physical function after the intervention (p < 0.01), but there were no further effects for the protein group (p > 0.05). Muscle mass did not improve after resistance training in either group (p > 0.05). In conclusion, 12 weeks of resistance training are enough to improve physical function in a post-hospitalized elderly population with no further benefits for the protein-supplemented group.

Published: October 2019

Background: Parents influence their children’s nutrition behavior. The relationship between parental influences and children’s nutrition behavior is often studied with a focus on the dyadic interaction between the parent and the child. However, parents and children are part of a broader system: the family. We investigated the relationship between the family nutrition climate (FNC), a family-level concept, and children’s nutrition behavior. Methods: Parents of primary school-aged children (N = 229) filled in the validated family nutrition climate (FNC) scale. This scale measures the families’ view on the consumption of healthy nutrition, consisting of four different concepts: value, communication, cohesion, and consensus. Parents also reported their children’s nutrition behavior (i.e., fruit, vegetable, water, candy, savory snack, and soda consumption). Multivariate linear regression analyses, correcting for potential confounders, were used to assess the relationship between the FNC scale (FNC-Total; model 1) and the different FNC subscales (model 2) and the child’s nutrition behavior. Results: FNC-Total was positively related to fruit and vegetable intake and negatively related to soda consumption. FNC-value was a significant predictor of vegetable (positive) and candy intake (negative), and FNC-communication was a significant predictor of soda consumption (negative). FNC-communication, FNC-cohesion, and FNC-consensus were significant predictors (positive, positive, and negative, respectively) of water consumption. Conclusions: The FNC is related to children’s nutrition behavior and especially to the consumption of healthy nutrition. These results imply the importance of taking the family-level influence into account when studying the influence of parents on children’s nutrition behavior.

Leishmaniasis and American trypanosomiasis are parasitic diseases that cause significant clinical, social and economic impact on the population of tropical and subtropical countries. Their current treatment is limited and presents multiple drawbacks, including high toxicity, high cost, lengthy treatment plans, as well as the emergence of resistant species. Therefore, there is a need to find new lead compounds with high potency against parasites and low toxicity in patients. In the present work, the bioguided fractionation of an endemic plant from the Canary Islands, Withania aristata, led to the identification of withanolide-type metabolites (1–3) with leishmanicidal and trypanocidal activities. Compounds 1 and 3 showed a significant dose-dependent inhibition effect on the proliferation of L. amazonensis promastigotes and T. cruzi epimastigotes, higher than the reference drugs, miltefosine and benznidazole, respectively. Moreover, compounds 1–3 were more potent (IC50 0.055–0.663 µM) than the reference drug against the intracellular amastigote stage of L. amazonensis, with a high selectivity index on murine macrophage cells (SI 58.66–216.73). Studies on the mechanism of death showed that the compounds induced programmed cell death or that which was apoptosis-like. The present findings underline the potential of withanolides as novel therapeutic antikinetoplastid agents.

Published: October 2019

Application of Na+-responsive DNA quadruplex hydrogels, which utilize G-quadruplexes as crosslinking points of poly(ethylene glycol) (PEG) network as cell culture substrate, has been examined. PEG-oligodeoxynucleotide (ODN) conjugate, in which four deoxyguanosine (dG4) residues are tethered to both ends of PEG, was prepared by modified high-efficiency liquid phase (HELP) synthesis of oligonucleotides and used as the macromonomer. When mixed with equal volume of cell culture media, the solution of PEG-ODN turned into stiff hydrogel (G-quadruplex hydrogel) as the result of G-quadruplex formation by the dG4 segments in the presence of Na+. PEG-ODN itself did not show cytotoxicity and the resulting hydrogel was stable enough under cell culture conditions. However, L929 fibroblast cells cultured in G-quadruplex hydrogel remained spherical for a week, yet alive, without proliferation. The cells gradually sedimented through the gel day by day, probably due to the reversible nature of G-quadruplex formation and the resulting slow rearrangement of the macromonomers. Once they reached the bottom glass surface, the cells started to spread and proliferate.
Numerical Simulation of Darcy–Forchheimer 3D Unsteady Nanofluid Flow Comprising Carbon Nanotubes with Cattaneo–Christov Heat Flux and Velocity and Thermal Slip Conditions

Published: October 2019

A mathematical model comprising Darcy Forchheimer effects on the 3D nanofluid flow with engine oil as a base fluid containing suspended carbon nanotubes (CNTs) is envisioned. The CNTs are of both types i.e., multi-wall carbon nanotubes (MWCNTs) and single-walled carbon nanotubes (SWCNTs). The flow is initiated by an exponentially stretched surface. The impacts of Cattaneo–Christov heat flux along with velocity and thermal slip conditions are key factors in the novelty of the defined model. The boundary layer notion is designed to convert the compact form of equations into the component shape. Appropriate transformations lead to differential equations with high nonlinearity. The final non-dimensional system is solved numerically by a “MATLAB” function known as bvp4c. For both CNTs, different graphical sketches are drawn to present the influence of arising parameters versus related profiles. The outcomes show that higher slip parameter boosts the axial velocity, whereas fluid temperature lowers for a sturdier relaxation parameter.
Exploring the Impact of Complex Multi-Level Governance Structures on the Societal Contribution of Universities to Knowledge-Based Urban Development
Authors: Gohari Savis , Medalen Tor , Aranya Rolee
Published: October 2019

The current debate aims to reconceptualize the changing role and missions of the university in today’s knowledge economy and investigate how universities’ knowledge resources can benefit urban development and inform the direction of changes in universities. However, there is a lack of empirical studies exploring how governance networks and the institutional conditions of universities in specific contexts can support, limit and/or incentivize the integration of academic activities into societal development. There is a discussion of the various and paradoxical components of university transformation (institutional and physical), affecting their societal contribution, which conceptualizes a holistic and integrated approach towards governance that previously has not been fully investigated. This paper will examine the co-location case of university campuses in Trondheim to explore the implications of a multilevel governance network for achieving the goals of sustainable and knowledge-based urban development. This paper suggests that engineering effective governance is challenging and that factors related to the culture of the institution and their connecting strategies, government priorities, and temporal factors have a great influence on universities’ contribution to their societies. While investigating governance in this topic requires political, cultural, and periodic review, focusing on the interactions of governance multi-layers, this paper concludes that governments’ control functions or some moderate hierarchical coordination is necessary to avoid the failure of university governance and unbalanced societal contributions.
An Efficient Data Transmission with GSM-MPAPM Modulation for an Indoor VLC System
Authors: Bao Jing-Jing , Hsu Chun-Liang , Tu Jih-Fu
Published: October 2019

As an emerging wireless communication technique, visible light communication is experiencing a boom in the global communication field, and the dream of accessing to the Internet with light is fast becoming a reality. The objective of this study was to put forward an efficient and theoretical scheme that is based on generalized spatial modulation to reduce the bit error ratio in indoor short-distance visible light communication. The scheme was implemented while using two steps in parallel: (1) The multi-pulse amplitude and the position modulation signal were generated by combining multi-pulse amplitude modulation with multi-pulse position modulation using transmitted information, and (2) certain light-emitting diodes were activated by employing the idea of generalized spatial modulation to convey the generated multi-pulse amplitude and position modulation optical signals. Furthermore, pulse width modulation was introduced to achieve dimming control in order to improve anti-interference ability to the ambient light of the system. The two steps above involved the information theory of communication. An embedded hardware system, which was based on the C8051F330 microcomputer and included a transmitter and a receiver, was designed to verify the performance of this new scheme. Subsequently, the verifiability experiment was carried out. The results of this experiment demonstrated that the proposed theoretical scheme of transmission was feasible and could lower the bit error ratio (BER) in indoor short-distance visible light communication while guaranteeing indoor light quality.

Published: October 2019

The growing scarcity and competition for water resources requires the urgent implementation of measures to ensure their rational use. Farmers need affordable irrigation tools that allow them to take advantage of scientific know-how to improve water use efficiency in their common irrigation practices. The aim of this study is to test under field conditions, and adjust where required, an automated irrigation system that allows the establishment of regulated deficit irrigation (RDI) strategies in a stone fruit orchard. For this, an automated device with an algorithm which combines water-balance-based irrigation scheduling with a feedback adjustment mechanism using 15 capacitive sensors for continuous soil moisture measurement was used. The tests were carried out in 2016 and 2017 in Vegas Bajas del Guadiana (Extremadura, Spain) on an experimental plot of ‘Red Beaut’, an early-maturing Japanese plum cultivar. Three irrigation treatments were established: control, RDI and automatic. The control treatment was scheduled to cover crop water needs, a postharvest deficit irrigation (40% crop evapotranspiration (ETc)) strategy was applied in the RDI treatment, while the Automatic treatment simulated the RDI but without human intervention. After two years of testing, the automated system was able to “simulate” the irrigation scheduling programmed by a human expert without the need for human intervention.

Antibiotics are extensively applied in aquaculture for the treatment of microbial infections and to improve production. Among various antibiotics, sulfonamides (SA) are popular in fish farming, and SA residues in the aquatic environment have detrimental effects on both ecosystem and human health. Understanding the fate of SA in the aquatic environment is a basic necessity to provide an approach for solving the current problem. In this study, a two-dimensional lattice Boltzmann model was introduced to investigate the transport and occurrence of SA in Laizhou Bay, a prosperous aquaculture area in China. The model is based on the shallow-water equations and advection-diffusion equation with the Bhatnagaar–Gross–Krook scheme. Experimental data are used to verify the model after numerical simulations and the results illustrate the accuracy of the proposed model. This model provides a potential universal method for the simulation of the fate of antibiotics in the aquatic environment.

Mengkaji pemikiran seorang tokoh cendekiawan Muslim adalah suatu upaya mulia agar kita sebagai penulis dan pembaca dapat mengetahui dan memahami hakekat dari pemikiran tokoh dimaksud. Sehubungan dengan hal tersebut, penulis dalam kesempatan ini ingin melakukan kajian singkat Pemikiran Ibnu Rusyd tentang Filsafat dan Agama  dengan harapan akan mengantar kita sebagai pembaca mengerti dan memahami apa sesungguhnya yang menjadi pemikiran seorang cendekiawan Muslim seperti Ibnu Rusyd.  Tulisan ini juga dimaksudkan untuk memenuhi tugas yang diberikan oleh Dr. A. Ilyas Ismail, MA sebagai Pengampu Mata Kuliah Filsafat Ilmu dalam kapasitas Penulis sebagai Mahasiswa pada Program Studi S3 (Doktor) Ilmu Hukum.

         Filsafat sebagaimana yang penulis fahami adalah suatu pemikiran yang mengarahkan seseorang untuk cinta kebijaksanaan sesuai pengertian secara etimologi dari kata “filsafat”, yang dalam bahasa Yunani disebut philoshopia (philos : cinta dan sophos : bijaksana)” (Sukarno Aburaera dkk, 2013 : 25). Dari pengertian ini kita diberikan pemahaman bahwa filsafat adalah upaya seseorang dalam melakukan perenungan untuk memperoleh pengetahuan yang luas sehingga yang bersangkutan dapat menjadi manusia bijaksana dan hasil pemikirannya bermanfaat bagi dirinya dan orang lain secara terpadu. Hal ini sesuai dengan Sabda Rasulullaah Sallallaahu ‘Alayihi wa Sallam bahwa “sebaik-baik manusia adalah yang bermanfaat bagi manusia laiinya”.
DOKTRIN LEX SPORTIVA VERSUS HUKUM KEOLAHRAGAAN NASIONAL
Authors: Riyanto Slamet
Published: October 2019

Doktrin Lex Sportiva dirumuskan sebagai ajaran mengenai hukum yang khusus mengatur tentang olahraga yang dibentuk oleh institusi komunitas olahraga itu sendiri dan berlaku serta ditegakkan oleh lembaga olahraga itu sendiri tanpa intervensi dari hukum positif suatu negara dan tanpa intervensi dari hukum internasional. Lex sportiva ini tegas-tegas menolak digunakannya hukum nasional suatu negara, baik dalam penyelenggaraan, pengawasan, pengendalian, maupun  penyelesaian sengketa olahraga cabang olahraga. Selain itu cabang-cabang olahraga juga menolak campur tangan atau intervensi  pemerintah atau negara dalam kekisruhan yang terjadi dalam organisasi cabang olaharaga. Bahkan federasi internasional cabang olahraga ini tidak segan-segan menjatuhkan sanksi kepada federasi nasional cabang olahraga dari suatu negara peserta yang pemerintah atau negaranya melakukan campur tangan atau intervensi terhadap penyelenggaraan cabang olahraga ini. Dalam konteks Indonesia, kehadiran peraturan perundang-undangan keolahragaan seringkali dimaknai oleh federasi internasional cabang olahraga dan atau penganut lex sportiva di Indonesia sebagai bentuk campur tangan atau intervensi negara terhadap penyelenggaraan sepakbola yang menjadi kewenangannya, sehingga harus ditolak. Mereka berpandangan bahwa Hukum Olahraga Nasional Indonesia yang dimanifestasikan dalam Undang-Undang Sistem Keolahragaan Nasional (UU SKN) dan 3 (tiga) Peraturan Pemerintah,  hanya boleh mengatur hal-hal yang berkaitan dengan olahraga dari sisi public interest-nya saja. Itupun dengan catatan bahwa norma-norma hukum dari peraturan perundang-undangan yang dibuat oleh Pemerintah Indonesia tersebut tidak mengintervensi terhadap Lex Sportiva. Jika UU SKN dan peraturan perundang-undangan lainnya mengatur terlalu jauh dan masuk ke ranah lex sportiva, maka dapat dipastikan olahraga di Indonesia tidak diakui sebagai bagian dari olahraga internasional. Disini dapat dikatakan telah terjadi benturan antara sistem hukum keolahragaan nasional sebagai salah satu alat pengembangan kedaulatan negara yang menganut paham positifisme dengan lex sportiva sebagai alat pengembangan kesejahteraan masyarakat yang menganut paham utilitiarisme.

Published: October 2019

The experiment with three different rootstock cultivars was set up in a commercial apple orchard at Nagykutas, which is situated in the western part of Hungary. The aim of our two-year-study was to determine the effect three different growing rootstock cultivars (M9, MM106 and seedling) on the flowering and productivity of 33 apple cultivars. Our observations included the following measurements: the date of the beginning and the end of flowering, flower density, fruit density, fruit numbers per tree and tree productivity. According to our results, it was found that the different growing rootstocks have a great determining effect on the above measurements. Our results showed that the flowering period was similar for all cultivars on the three different rootstocks. However, the flowering and the fruit setting decreased in the order M9, MM106 and seedling rootstocks. In contrast, the fruit number per tree followed, in decreasing order, MM106, seedling and M9 rootstocks.
The house, the city, and the colony in the works of Aphra Behn: Gendered spaces and the freedoms and dangers they afford.
Authors: Rubik Margarete
Published: October 2019

In Behn’s works the house affords no security for women, as men may force their way in, or relatives collude in the sexual violation of women. However, men, too, are threatened and cuckolded in their own houses. Not even convents are safe spaces for either sex. Outdoor spaces promise freedom from supervision but harbor threats to both women’s and men’s honor. The Whig inhabitants of the City of London are ridiculed, but female characters dabbling in politics are no more likeable, though Behn sympathizes with women claiming a right to public visibility. The racialized colonial space offers upward social mobility to Englishmen and –women, and to the latter also the freedom to partake in pastimes and occupations traditionally connoted as male.

The study on Attrition level is to know the employee’s interest in how the organization were giving importance to the employees. Attrition is a critical issue and pretty high in the industry. It’s a major problem which highlights in all the organizations. Though the term ‘ATTRITION’ is common, due to attrition, the organization will face down in their growth, “Attrition is said to be the gradual reduction in the number of employees through retirement, resignation or death. It can also be said as Employee Turnover or Employee Defection”. Retaining employees is a critical and ongoing effort. One of the biggest challenges in having managers in the place that understands it is their responsibility to create and sustain an environment that fosters retention. Staff requires reinforcement, direction and recognition to grow and remain satisfied in their positions. The main objectives of this study are to know the reasons why attrition occurs, to identify the factors which make employees dissatisfy, to know the satisfactory level of employees towards their job and working conditions. This study is analyzing by taking questioner with individual employees, and the random sample was 100, this study gives some information to the organization what to do and not to do. The organization should improve their basic needs.

Published: October 2019

Históricamente el hiperparatiroidismo primario ha sido una patología caracterizada por el hallazgo de un adenoma paratiroideo, sin embargo el diagnóstico a la luz de un doble adenoma, ha permitido abrir la discusión frente a una nueva forma de presentación, con diferentes implicaciones clínicas que hacen necesaria la participación coordinada del grupo de profesionales involucrados tanto en el escenario clínico como quirúrgico, y que permitan enfrentar este reto diagnóstico con el mejor conocimiento y los recursos disponibles. Presentamos el caso de una paciente en quien tras una larga historia de episodios de urolitiasis, se logró identificar dos adenomas paratiroideos que no respondieron al manejo con dosis altas de cinacalcet pero con un resultado exitoso tras el manejo quirúrgico.
Die Grenzen und Möglichkeiten des Ausdrucks
Authors: Franke Julia
Published: October 2019

Im vorliegenden Text wird zunächst die Frage gestellt, wo die Grenzen der menschlichen Ausdrucksmöglichkeit liegen. Anschließend werden einige Überlegungen von Moritz Schlick als Antwort auf diese Frage dargestellt. Im ersten Abschnitt wird erörtert, dass nach Schlick die Erlebnisinhalte als das ‚Unausdrückbare‘ bestimmt werden können. In diesem Zusammenhang wird auch der Begriff der ‚internen Relationen‘ diskutiert. Zum Abschluss des ersten Abschnitts wird die These von der ‚Unausdrückbarkeit des Inhalts‘ als ‚Unsagbarkeitsthese‘ festgehalten. Anschließend wird im zweiten Abschnitt der Begriff ‚externe Relationen‘ eingeführt und dem der ‚internen Relationen‘ gegenübergestellt. Dabei wird erörtert, was als das Ausdrückbare‘ übrig bleibt, wenn man die ‚Unsagbarkeitsthese‘ akzeptiert. Es zeigt sich, dass es sich hiernach bei allen Aussagen um reine Strukturaussagen handelt. Der abschließende Abschnitt gibt einen Ausblick darauf, inwiefern die ‚Unsagbarkeitsthese‘ für Schlicks erkenntnistheoretischen Strukturalismus von zentraler Bedeutung ist.
