Cahn–Hilliard equation on the boundary with bulk condition of Allen–Cahn type
Authors: Colli Pierluigi , Fukao Takeshi 
Published: July 2018

Abstract
The well-posedness of a system of partial differential equations with dynamic boundary conditions is discussed.
This system is a sort of transmission problem between the dynamics in the bulk Ω and on the boundary Γ.
The Poisson equation for the chemical potential and the Allen–Cahn equation for the order parameter in the bulk Ω are considered as auxiliary conditions for solving the Cahn–Hilliard equation on the boundary Γ.
Recently, the well-posedness of this equation with a dynamic boundary condition, both of Cahn–Hilliard type, was discussed.
Based on this result, the existence of the solution and its continuous dependence on the data are proved.

Published: July 2018

Abstract
The study was aimed at exploring the effects of applying ordinary and nano zeolite on the soil pH, soil available cadmium (Cd) content, soil Cd speciation and Cd uptakes by tobacco using pot experiment with simulated Cd contaminated soil indoors. The results showed that soil pH increased and available Cd content reduced with the amount of ordinary and nano zeolite increasing. Compared with the control, the application of ordinary and nano zeolite increased soil pH at 0.47 - 1.05 and 0.73 - 1.57, respectively, and reduced the available Cd contents at 19.3% - 32.7% and 23.2% - 40.5%, respectively. In addition, soil pH had significantly negative correlation with available Cd content in each treatment (p<0.05). Nano zeolite could more effectively reduce Cd contents of all parts of tobacco than ordinary zeolite with the same amount treatments, and Cd content in all parts of tobacco plants was positively correlated with soil available Cd content. The content of exchangeable Cd (EXE) in soil decreased to some extent with different zeolite treatments, application of nano zeolite was better than that of application of ordinary zeolite in reducing Cd bioavailability and transferability. Overall, application of nano zeolite has an advantage over ordinary zeolite in reducing available Cd content in soil and Cd content in tobacco.
Global dynamics and parameter identifiability in a predator-prey interaction model
Authors: Tripathi Jai Prakash , Meghwani Suraj S. , Tyagi Swati , Abbas Syed 
Published: July 2018

AbstractThis paper discusses a predator-prey model with prey refuge. We investigate the role of prey refuge on the existence and stability of the positive equilibrium. The global asymptotic stability of positive interior equilibrium solution is established using suitable Lyapunov functional, which shows that the prey refuge has no influence on the permanence property of the system. Mathematically, we analyze the effect of increase or decrease of prey reserve on the equilibrium states of prey and predator species. To access the usability of proposed predator-prey model in practical scenarios, we also suggest, the use of Levenberg-Marquardt (LM) method for associated parameter estimation problem. Numerical results demonstrate faithful reconstruction of system dynamics by estimated parameter by LM method. The analytical results found in this paper are illustrated with the help of suitable numerical examples
Antibacterial evaluation of CNF/PVAm multilayer modified cellulose fiber and cellulose model surface
Authors: Chen Chao , Ek Monica 
Published: July 2018

Abstract
Earlier studies have shown that 3-layer-modified cellulose fibers with poly(acrylic acid) (PAA) as the middle layer between two cationic polyelectrolyte polyvinylamine (PVAm) layers have strong antibacterial efficacy in terms of both bacteria adsorption and bacterial growth inhibition. In the present work, the fossil-based PAA middle layer was replaced by sustainable wood-based cellulose nano-fibrils (CNF), i. e., the fibers were modified by a 3-layer PVAm/CNF/PVAm system. Interestingly, the antibacterial efficacy of this system was greater than that of the previous PVAm/PAA/PVAm system. A higher salt concentration and lower assembly pH in the multilayer build-up resulted in better bacterial reduction. As the surface of a cellulose fiber is heterogeneous, making it difficult to characterize and visualize at high resolution, more homogeneous cellulose model surfaces were prepared by spin coating the dissolved cellulose fiber onto a silica surface to model the fiber surface. With increasing ionic strength, more aggregated and heterogeneous structures can be observed on the PVAm/CNF/PVAm modified model surfaces. The adsorbed bacteria distributed on the structured surfaces were clearly seen under fluorescence microscopy. Adsorbed amounts of bacteria on either aggregate or flat regions were quantified by scanning electron microscopy (SEM). More adsorbed bacteria were clearly seen on aggregates than on the flat regions at the surfaces. Degrees of bacteria deformation and cell damage were also seen under SEM. The surface roughness of the modified model surfaces was examined by atomic force microscopy (AFM), and a positive correlation was found between the surface roughness and the bacterial adhesion. Thus, an additional factor that controls adhesion, in addition to the surface charge, which is probably the most dominant factor affecting the bacteria adhesion, is the surface structures, such as roughness.
Transmedia branding: Brands, narrative worlds, and the mcwhopper peace agreement
Authors: Scolari A. Carlos 
Published: July 2018

Abstract
In recent years there has been much discussion about the links between brands and storytelling. This article briefly describes transmedia storytelling, reflects on some exemplary works to understand its cultural dynamics, and then focuses on one particular aspect: the development of transmedia strategies in branding. This article delves into that area where branding melts and recombines with storytelling, keeping an eye on transmedia worlds throughout. After presenting a semio-narratological analytical model the article applies the categories to Burger King’s successful and internationally recognized McWhopper campaign (Campaign, Brief. 2015. Y&R’s Burger King “McWhopper” campaign: How a big idea from little New Zealand went global (interview to Tom Paine). Campaign Brief December 31. http://www.campaignbrief.com/ (accessed 16 October 2016)). The analysis spans from the construction of McWhopper’s storytelling to the positioning of competitors in this particular transmedia narrative world. The article concludes with a series of reflections and recommendations for applying semio-narratologic categories to transmedia branding analysis and design.
A Word on Kosovo’s First Ten Years
Authors: Austin Robert C. 
Published: July 2018

Abstract
Kosovo celebrated ten years of fraught independence in February. While there were some good reasons to celebrate, Kosovo still hovers between a failed and a functioning state. Its main economic indicators are extremely bad with no signs of improving. Unemployment, particularly among its youth, is feeding an ongoing brain drain. The legacy of the United Nations Mission (UNMIK) and now the European Union Mission (EULEX) is mixed, but neither was successful in creating the conditions for Kosovo to function as a normal state. Agreements between Belgrade and Prishtina to provide more rights to the Serb communities especially in the north have undermined Kosovo’s sovereignty. Now, the buzz in Prishtina speaks of a territorial swap between Serbia and Kosovo that would pave the way for mutual recognition. The domestic elite have proven more interested in short term survival and profit than in making historic progress. A stale consensus prevails that maybe this is the best that can be hoped for.
First representatives of (210)-oriented perovskite variants−Synthesis, crystal structures and properties of the new 2D hybrid perovskites A[HC(NH2)2]PbI4; A=[C(NH2)3], [HSC(NH2)2]
Authors: Daub Michael , Hillebrecht Harald 
Published: July 2018

Abstract
Single crystals of [C(NH2)3][HC(NH2)2]PbI4 (GuFAPbI4) and [HSC(NH2)2][HC(NH2)2]PbI4 (TuFAPbI4) were obtained from solutions of the binary halides in HI or DMF. Large crystals grown from HI are dark-brown while single phase powders synthesized from DMF are orange. The crystal structure of GuFAPbI4 (I2/m, Z=12, a=14.3147(2), b=12.7591(2), c=25.7377(4)Å), β=101.459(1), 4256 refl., 196 param., R1=0.024, wR2=0.061) represents a 2D perovskite with a new motif similar to Ruddlesden-Popper phases (AX)m(A′BX3)n and m=n=1. The layers are formed by corner-sharing PbI6 octahedra. According to the cut-out of the 3-D perovskite the structure of GuFAPbI4 can be assigned as a (210)-oriented representative. So one octahedron is linked in trans-position and two in cis-orientation. The structure of TuFAPbI4 (P21/n, Z=12, a=14.4208(6), b=12.7545(7), c=26.3982(11) Å), β=100.609(3)°, 6808 refl., 275 param., R1=0.048, wR2=0.096) represents a simple distortion variant of GuFAPbI4. GuFAPbI4 and TuFAPbI4 were further characterized by vibrational spectroscopy and optical spectroscopy. The optical band gap was determined as 2.34 eV in agreement to the observed color. So both compounds are not suitable as a dye in the PSC perovskite solar cell. Similar to other Pb-containing 2D perovskites there is a significant excitonic peak (2.31 eV). TuFAPbI4 represents the first example with protonated thiourea as an organic cation. Therefore, we characterized protonated thiourea iodide and introduce protonated thiourea [HSC(NH2)2]+ as a new cation for hybrid halogeno perovskites.

Published: July 2018

Background and Purpose:
Prolonged sedentary time and limited physical activity can result in deleterious effects on health and mobility, especially for older adults with fall-related hip fracture. Therefore, the purpose of this study was to examine the effect of a multidisciplinary clinic on sedentary behavior and physical activity (prespecified secondary outcomes) and provide descriptions of activity patterns over 1 year for men and women.

Methods:
We conducted a parallel-group, single-blinded randomized controlled trial comparing a multidisciplinary clinic and usual care (intervention) with usual care (control). We recruited 53 community-dwelling older adults aged 65+ years who were 3 to 12 months postfracture and collected data at baseline, 6, and 12 months; study staff were blinded to group allocation. The clinic included a geriatric assessment by the geriatrician, physiotherapist, and occupational therapist. Referrals were made to other professionals, when indicated. We collected the accelerometer-measured sedentary behavior and physical activity at 3 time points. We used linear mixed-effects models to compare groups at 6 and 12 months and mixed models to compare outcomes between men and women.

Results:
Participants were sedentary for more than 10 hours of a 13-hour day, and there were no significant differences between the study groups at 6 months (2.4 [95% confidence interval: −22.4 to 27.2] minutes) or 12 months (−3.7 [95% confidence interval: −33.6 to 26.1] minutes). Compared with women, men spent 47.2 min/d more in sedentary time (P = .052) and 43.8 min/d less in light physical activity (P = .047).

Discussion:
Older adults after hip fracture spend prolonged periods of waking hours sedentary with very little activity.
ETOS KERJA DALAM EKONOMI GLOBAL (KASUS MASYARAKAT MUSLIM MELAYU PALEMBANG)
Authors: Ritawati Raden Ayu 
Published: July 2018

The purpose of this research is to know the influence of Malay and Islam in shaping the social character of Palembang Malay workers in global economic development. The Islamic economic norms embedded and rooted in the local social identity of the local Malays are the key determinants of evaluative aspects of a judging nature.
This research departs from the reason as Ushul Fiqih's written adage says "Al-Muhafazhatu'alal 'qadimis salih wal-akhdzu bil jadidil ashlah" which means "Maintaining a good old value and seeking new value better.” Field research with the participation of observations and in-depth interviews uses a qualitative approach. Respondents in this study are Palembang original Malay Muslim community, spread over 14 districts using random sampling technique. While the method of data analysis is cyclical of three stages: data collection, data display and data verification. The results of this study prove that excessive material competition in the global economy has resulted in an anomic Palembang Malay society. Achievements in the economic field, it turns out to have transformed Palembang Malay people into a generation that is uprooted from values, fragile from the spiritual aspect, give up easily and lose socio-economic footing. The relationship of Malayness and Islamism obscures the role and competitiveness of Palembang Malay Muslims themselves in the global economic arena.
Genetic Polymorphisms within Interferon-λ Region and Interferon-λ3 in the Human Pathophysiology: Their Contribution to Outcome, Treatment, and Prevention of Infections with Hepatotropic Viruses
Authors: Grzegorzewska Alicja E. 
Published: July 2018

:Genetic polymorphisms within the interferon λ (IFN-λ) chromosomal region, mainly rs12979860 of IFN-λ4 gene (IFNL4), are known as associated with spontaneous hepatitis C virus (HCV) resolution and sustained viral response to therapy with pegylated interferon- α and ribavirin. Strong linkage disequilibrium of IFNL4 rs12979860 with IFNL4 rs368234815, which is casually associated with HCV spontaneous and therapeutical eradication, at least partially explains favorable HCV outcomes attributed to major homozygosity in rs12979860. Effects of IFN-based antiviral treatment are associated with pretreatment expression of the IFN-λ1 receptor, expression of hepatic IFN-stimulated genes, production of IFN- λ4, and preactivation of the JAK-STAT signaling. Nowadays direct-acting antivirals (DAAs) became a potent tool in the treatment of hepatitis C, but IFN-λs are still under investigation as potential antivirals and might be an option in HCV infection (DAA resistance, recurrent viremia, adverse effects).:Patients with altered immunocompetence are especially prone to infections. In uremic subjects, polymorphisms within the IFN-λ chromosomal region associate with spontaneous HCV clearance, similarly like in the non-uremic population. Circulating IFN-λ3 shows a positive correlation with plasma titers of antibodies to surface antigen of hepatitis B virus (anti-HBs), which are crucial for protection against hepatitis B virus. More efficient anti-HBs production in the presence of higher IFN-λ3 levels might occur due to IFN-λ3-induced regulation of indoleamine 2,3-dioxygenase (IDO) expression. IFN-stimulated response element is a part of IDO gene promoter. It is worth further investigation whether IDO gene, circulating IDO, genetic polymorphisms within the IFN-λ region, and circulating IFN-λ3 act in concordance in immunological response to hepatotropic viruses.

Published: July 2018

Background:
Cell therapy is an important strategy for the treatment of incurable diseases
including those that occur in the Central Nervous System (CNS). Among different strategies, the
method of delivering or transplantation of cells into the brain has shown significant effects on regeneration.
In this study, a new protocol has been developed for the transplantation of adipose tissuederived
stem cells into the brain through Cerebrospinal Fluid (CSF) in rat models.

Methods:
For this purpose, a wide range of ages (7-30 days old) of male neonates of Wistar rats was
used. Moreover, human adipose tissue was obtained from a superficial layer of abdomen through liposuction
surgery. The size of the inserted part of needle to access middle cranial fossa and subarachnoid
space in animals with an average weight of 10-80 g was determined. In addition, to confirm the entrance
of needle into the subarachnoid space, CSF was aspirated slowly and then injection was done
within two minutes.

Results:
The findings showed the presence of transplanted human Adipose-Derived Stem Cells
(hADSC) in the cerebellum and basal ganglia following three days and also after two months that confirmed
the entrance of transplanted cells into the cerebrospinal fluid and migration of them into the
brain tissue. All the animals survived after the transplantation process, with the lowest side effects
compared to the available conventional methods.

Conclusion:
It can be concluded that the cells could be efficiently transplanted into CSF through subarachnoid
space by injection via superior orbital fissure with a minimally invasive technique.

Authors: Lal Deepak Kumar , Barisal Ajit Kumar 
Published: July 2018

Background:Due to the increasing demand for the electrical power and limitations of conventional energy to produce electricity.Methods:Now the Microgrid (MG) system based on alternative energy sources are used to provide electrical energy to fulfill the increasing demand. The power system frequency deviates from its nominal value when the generation differs the load demand. The paper presents, Load Frequency Control (LFC) of a hybrid power structure consisting of a reheat turbine thermal unit, hydropower generation unit and Distributed Generation (DG) resources.Results:The execution of the proposed fractional order Fuzzy proportional-integral-derivative (FO Fuzzy PID) controller is explored by comparing the results with different types of controllers such as PID, fractional order PID (FOPID) and Fuzzy PID controllers. The controller parameters are optimized with a novel application of Grasshopper Optimization Algorithm (GOA). The robustness of the proposed FO Fuzzy PID controller towards different loading, Step Load Perturbations (SLP) and random step change of wind power is tested. Further, the study is extended to an AC microgrid integrated three region thermal power systems.Conclusion:The performed time domain simulations results demonstrate the effectiveness of the proposed FO Fuzzy PID controller and show that it has better performance than that of PID, FOPID and Fuzzy PID controllers. The suggested approach is reached out to the more practical multi-region power system. Thus, the worthiness and adequacy of the proposed technique are verified effectively.
Social Media and Voluntary Nonfinancial Disclosure: Evidence from Twitter Presence and Corporate Political Disclosure
Authors: Lei Lijun (Gillian) , Li Yutao , Luo Yan 
Published: July 2018

ABSTRACT
This study uses a sample of 1,316 firm-year observations of S&P 500 companies (2012–2016) to investigate whether and how social media (i.e., Twitter) affects firms' voluntary nonfinancial disclosure (i.e., corporate political disclosure). Our results show that Twitter-adopting firms are generally more transparent in their disclosure of corporate political contributions and of related policies and board oversight. Moreover, firms with more Twitter followers and firms whose corporate political activities are targeted in more Twitter messages are more transparent in such disclosures. Our cross-sectional analysis suggests that this effect is stronger for firms whose stakeholders are more active on Twitter and firms that are less visible or more reputable. Our results remain robust to different econometric model specifications and controlling for alternative social media platforms. Taken together, our findings suggest that social media (i.e., Twitter) presence exerts pressure on firms' voluntary nonfinancial disclosure practices (i.e., corporate political disclosure).

Access to medically assisted reproduction for legal persons: Possible?
Authors: Konečná Hana , Nováková Karolína 
Published: July 2018

Abstract
Along with the rapid growth that the field of assisted reproduction has experienced over the last few years, numerous ethical issues have arisen and need to be discussed thoroughly. One of them is the limitation of access to assisted reproduction techniques. Because no one should be discriminated against, it is essential to substantiate every single refusal of access carefully. The criterion of welfare of the child is used most frequently. In this paper, we propose a thought experiment aiming at contributing to the discussion by demonstrating that this criterion, even in its strictest form, can easily allow access to assisted reproduction for legal persons as well.
Spinozian consequentialism of ethics of social consequences
Authors: Joppová Michaela Petrufová 
Published: July 2018

Abstract
The present article deals with specific normative concepts of Spinoza’s ethical system and compares them to certain aspects of the theory of ethics of social consequences. At first, a way to approach the problem of normativity in Spinoza is presented, concentrating on the obligatory character of rational - or intellectual - motives. Then, theoretical evidence is presented which links Spinoza to normative-ethical consequentialism. The basis for a consequentialist model of Spinoza’s ethics is the concept of perfection, and on this basis it seems possible to consider its compatibility with non-utilitarian forms of consequentialism, such as ethics of social consequences. Conclusively, the paper’s aim is to present the possibility of considering Spinozian consequentialism as a non-utilitarian consequentialism, while considering ethics of social consequences as a contemporary form of Spinozian consequentialism.
Specifics of introducing a code of ethics into the academic environment
Authors: Lačný Martin , Lukáčová Jana , Kovalčíková Iveta 
Published: July 2018

Abstract
The implementation of tools and techniques of the management of ethics in the academic environment has its own peculiarities arising from the nature of the expert, scientific, pedagogical, but also administrative work of university staff, requiring a considerable degree of autonomy and freedom. The aim of this case study is to present the views of university teachers and PhD students from a selected faculty of a public university in Slovakia on the implementation of tools and techniques for the management of ethics and to identify specific risks associated with the nature of the code of ethics and its introduction into practice. Qualitative research was conducted using focus groups during the implementation of the code of ethics, while quantitative research was subsequently conducted by an anonymous electronic questionnaire shortly after the introduction of the code into practice.
