Authors: Chen Xi , Dai Ying 
Published: July 2018

Abstract
It is analyzed the wetting front of the Richards’ equation (RE) for horizontal infiltration problem with impervious layer in a finite medium, and obtained an approximate analytical solution by the series expansion technique. The present approximation is suitable for arbitrary diffusivity in RE and applied to simulate the changes of saturation after the front pass through the impervious point. Two examples about power law diffusivity are analyzed to confirm the accuracy of present solution.
Taxation of Non – Resident Legal Entities in Romania. Case: Rmms vs. Anaf Brăila
Authors: Dumiter Professor Florin , Jimon Ștefania 
Published: July 2018

Abstract
The taxation of non - resident economic entities supposes the establishment of an administrative framework as fair, efficient, effective and comprehensible as possible, fact due to the multifaceted nature of the concept of profits generated by an enterprise and which depend on some items as: the foundation of incomes sources, the methods of valuation and collecting taxes, as well as different rules of establishment of some tax thresholds in different situations. Taking into account the legal doctrine, as well as jurisprudence, respectively the national and international tax practices, we can notice the fact that the profits of enterprises are founded, stricto sensu, on tax declarations made by companies. Therefore, we consider very important, in this way, the technical capability of tax administrations regarding the establishment, implementation and coordination of some good practice procedures. In this article, we have tackled the treatment regarding the taxation of non - resident economic entities in Romania. The first part of the paper represents a truth caveat in which is presented and analysed the international and European theoretical framework of legal and tax treatment of non - resident economic entities. The second part of the paper represents a quid pro quo of taxing of non - resident economic entities in Romania, in which are analyzed the taxing stipulations established on national level. The final part of the article is enriched with the presentation and analysis of a particular case regarding the taxation of non - resident economic entities in Romania. The conclusion resulted from this article highlights the fact that Romania had made important steps regarding ―the adjustment‖ of national tax legislation, as well as the permanent improving of tax administration framework in the field of non - resident economic entities taxation in Romania.

Die Analyse synaptischer Plastizität auf Einzelzellebene mit Hilfe der STDP
Authors: Edelmann Elke , Leßmann Volkmar 
Published: July 2018

Zusammenfassung
Mithilfe des Patch clamp-Verfahrens können die molekularen Prozesse, die der Langzeitpotentierung (LTP) und der Langzeitdepression (LTD) zugrunde liegen, auf der Ebene eines einzelnen postsynaptischen Neurons (Nervenzelle) in akut isolierten Gehirnschnitten untersucht werden. Über die in der Ableitelektrode enthaltene Pipettenlösung können dabei Inhibitoren intrazellulärer Prozesse in das postsynaptische Neuron eingebracht werden, um so die an der synaptischen Plastizität beteiligten Signalwege zu identifizieren. Zur Untersuchung der synaptischen Plastizität wurden in den letzten Jahren zunehmend Protokolle herangezogen, die durch eine minimale Anzahl von synaptischen Stimulationen mit niedriger Frequenz robuste LTP oder LTD auslösen. Zu diesen Stimulationsmustern gehört die sogenannte Spike timing-dependent plasticity (STDP). Sie kann durch wiederholtes nahezu gleichzeitiges Feuern von Aktionspotenzialen (APs) im präsynaptischen und im nachgeschalteten postsynaptischen Neuron induziert werden, wenn diese APs mit einer kurzen zeitlichen Verzögerung von ca. 5–20 ms ausgelöst werden. Während „Vorwärtspaarungen“ mit kurzem positiven Zeitversatz (erst prä- dann postsynaptisches AP) LTP auslösen, führt „Rückwärtspaarung“ (erst post- dann präsynaptisches AP) zu LTD. Zusätzlich zur Abfolge (vorwärts oder rückwärts) und der zeitlichen Verzögerung der APs, ist die Wirkung von neuromodulatorischen Transmittern (z. B. Dopamin, Acetylcholin, Noradrenalin) und die synaptische Freisetzung von intrazellulären Mediatoren der synaptischen Plastizität (z. B. BDNF, Endocannabinoide) kritisch an der Regulation von STDP-Protokollen beteiligt. In diesem Übersichtsartikel fokussieren wir uns auf die Rolle dieser Mediatoren und Modulatoren bei durch STDP ausgelösten synaptischen Plastizitätsphänomenen.
MHD nonaligned stagnation point flow of second grade fluid towards a porous rotating disk
Authors: Khan Najeeb Alam , Naz Farah , Khan Nadeem Alam , Ullah Saif 
Published: July 2018

Abstract
This paper provides analytical solution of the non-aligned stagnation point flow of second grade fluid over a porous rotating disk in the presence of a magnetic field and suction/injection at the disk surface. The mathematical formulation of the fluid model is obtained in terms of partial differential equations (PDEs). The PDEs governing the motion are transformed into a system of ordinary differential equations (ODEs) by means of a similarity transformation and these corresponding nonlinear ODEs are solved by employing the homotopy analysis method (HAM) and the convergence analysis of the presented method is also performed graphically. An inclusion of the influences of various admissible parameters has been shown numerically and graphically on the flow field. Furthermore, comparison is made and it concedes that the obtained results are found to be in good agreement with results existing in literature.
A note on Riccati-Bernoulli Sub-ODE method combined with complex transform method applied to fractional differential equations
Authors: Abdelrahman Mahmoud A.E. 
Published: July 2018

AbstractIn this paper, the fractional derivatives in the sense of modified Riemann–Liouville and the Riccati-Bernoulli Sub-ODE method are used to construct exact solutions for some nonlinear partial fractional differential equations via the nonlinear fractional Zoomeron equation and the (3 + 1) dimensional space-time fractional mKDV-ZK equation. These nonlinear fractional equations can be turned into another nonlinear ordinary differential equation by complex transform method. This method is efficient and powerful in solving wide classes of nonlinear fractional order equations. The Riccati-Bernoulli Sub-ODE method appears to be easier and more convenient by means of a symbolic computation system.
Cattaneo -Christov heat flux model for magnetohydrodynamic flow in a suspension of dust particles towards a stretching sheet
Authors: Mamatha Upadhya S. , Mahesha  , Raju C.S.K. 
Published: July 2018

Abstract
In the present paper, the flow of an incompressible, electrically conducting dusty fluid over a stretching sheet is considered. The Cattaneo- Christov heat flux theory is employed to control the thermal boundary layer. The flow equations are transformed into nonlinear ordinary differential equations (NODEs) and which are solved with help of Runge-Kutta 4th order method. Flow equations are examined with respect to boundary conditions namely prescribed wall temperature (PWT) and prescribed heat flux (PHF) cases. In general PWT and PHF boundary conditions are very useful in the industrial as well as manufacturing up and down processes. Impact of the emerging parameters on the dimensionless velocity and temperature as well as friction coefficient and local Nusselt number are examined. We also validated my results with already available literature. It is found that the heat transfer rate of the flow in PWT case is higher than that of PHF case. These results can help us to conclude that for higher heating processes (Heating industries) PWT case and lesser heating processes (Cooling industries) PHF boundary condition is useful.

Vor diesem Hintergrund fragt sie nach der funktionalen und wesentlichen Seite von Spiritualität in der Diakonie. Theologie hat dabei für die Diakonie eine Erinnerungs- und eine Begleitungsfunktion. Auf der Basis des Rechtfertigungsverständnisses kann v. a. evangelische Theologie mit der Diakonie herausfinden, wo und wie sich für Klienten und Mitarbeiter/-innen Freiräume auftun, die mit Spiritualität sinn- und identitätsstiftend gefüllt werden können. Theologie selbst aktualisiert in diesem Dialog ihre eigenen Theorien.
Implizite Spiritualität
Authors: Maidl Lydia 
Published: July 2018

ZusammenfassungIn der Pflege legt sich durch die Anwendung traditioneller Bedürfnismodelle die Versuchung nahe, auf Spiritualität in gleicher Weise wie auf andere Bedürfnisse einzugehen. Dadurch wird die spezifische Dynamik des spirituellen Sehnens und Begehrens nicht angemessen berücksichtigt. Die zentrale Frage ist, wie menschliche Bedürfnisse und ein unstillbares Sehnen, das oft als Sehnsucht nach dem Göttlichen gedeutet wurde, zusammenhängen. Das entsprechende lateinische Wort istdesiderium. Es ist ein Schlüsselbegriff christlicher Spiritualität. Der folgende Beitrag erläutert psychologische und philosophische Einsichten, die mit diesem Begriff verbunden sind, und zeigt, wie sie den Gegenwartsdiskurs voranbringen. Zentral ist dabei die Einsicht des Thomas von Aquin, dass das sehnsuchtsvolle Verlangen nach letztem Glück in jedem Bedürfnis verborgen anwesend ist. Dies bringt der Terminus „implizite Spiritualität“ zum Ausdruck. Abschließend werden Impulse für Spiritual Care formuliert. Auch für die virulente Frage, welcher Spiritualitätsbegriff für Spiritual Care hilfreich ist, ergeben sich Einsichten.
Investigating the Effect of Silica Aerogel Nanoparticles on the Kinetics of AGET ATRP of Methyl Methacrylate
Authors: Karimi Maryam , Davoudizadeh Soroush , Bahadorikhalili Saeed , Khezri Khezrollah 
Published: July 2018

Abstract
Hexamethyldisilazane-modified silica aerogel nanoparticles were used for in situ polymerization of methyl methacrylate by activators generated by electron transfer for atom transfer radical polymerization (AGET ATRP) to synthesize tailor-made PMMA nanocomposites. Appropriate dispersion of silica aerogel nanoparticles in the monomer solution and improvement in interfacial interaction between the PMMA matrix and nanoparticles are two main reasons for application of HMDS-modified silica aerogel nanoparticles. Nitrogen adsorption/desorption isotherm was employed to examine surface area and structural characteristics of the HMDS-modified silica aerogel nanoparticles. Evaluation of size distribution and morphological studies were also performed by SEM and TEM. Conversion and molecular weight determinations were carried out using GC and SEC, respectively. Addition of 3 wt% HMDS-modified silica aerogel nanoparticles leads to decrement of conversion from 85 to 64%. Molecular weight of PMMA chains also decreases from 13,912 to 10,810 g⋅mol−1 by addition of only 3 wt% HMDS-modified silica aerogel nanoparticles; however, polydispersity index values increases from 1.18 to 1.51. Linear increase of ln(M0/M) with time for all the samples shows that polymerization proceeds in a living manner. In addition, suitable agreement between theoretical and experimental molecular weight in combination with low PDI values can appropriately demonstrate the living nature of the polymerization. TGA results indicate that by increasing HMDS-modified silica aerogel nanoparticles content, slight improvements in thermal stability of the nanocomposites were obtained. DSC results show a decrease in Tg from 86.9 to 80.1°C by addition of 3 wt% HMDS-modified silica aerogel nanoparticles.
Kontrowersje wokół umowy o pomocy przy zbiorach
Authors: Surdykowska Barbara 
Published: July 2018

Ustawą z 13.4.2018 r. o zmianie ustawy o ubezpieczeniu społecznym rolników oraz niektórych innych ustaw, ustawodawca wprowadził do sytemu prawnego nowy typ umowy – umowę o pomocy przy zbiorach. Mimo że odnosi się ona do wykonywania konkretnych czynności na rzecz rolnika, a więc dotyczy zatrudnienia w sensie ekonomicznym, nie jest to typ umowy o pracę. Konstrukcja umowy nie zawiera gwarancji prawa do bezpiecznych i higienicznych warunków pracy (między innymi w obszarze czasu pracy, przerw w pracy czy norm dotyczących dźwigania). Z tego względu wzbudza wątpliwości co do zgodności z art. 66 Konstytucji RP oraz tzw. Dyrektywą ramową bhp. Konstrukcja umowy o pomocy przy zbiorach wydaje siębyć także sprzeczna z celami określonymi w Europejskim filarze praw socjalnych.
