Authors: Wahab Fazal , Azim Syed Wasif , Jan Muhammad Ayub
Published: September 2020

The post 2001conflict and violence in Swat, northern Pakistan, has devastated different arenas of the social fabric of the Pukhtuns living in the region. In this context, the impact of conflict and associated violence on Pukhtu poetry and poets of the region is highly significant. During the conflict, the ‘space’ for the literary people shrunk, which also played an important role in the transformation of local poetry and adopting new subjects with the prominence of themes like violent extremism and terror in the poetry. Moreover, this study uses trauma and testimony theories to identify and understand the traumatic events and the process of testimony in indigenous Pukhtu poetry. The arguments are based on 18 in-depth interviews with poets and intellectuals from Matta Tehsil (administrative unit) of Swat combined with ethnographic observation and published work of poets from the same administrative unit

Published: September 2020

The vast majority of children spend the significant amount of time using media devices in order to gratify their social needs and to gain information and entertainment, but its impact on young children is certainly undeniable. Keeping this perspective in mind, children are required to be attentive to use media wisely and appropriately and this can be possible by providing them proper teaching of media that is called “Media Literacy” which is unfortunately an “alien concept” in Pakistan. This study conducts survey with the primary school going children between the age group of 8-13 years. The findings suggested that children have an easy access to different media both at school and at home from very early age. The only way to empower children explore their media world positively is to impart the media literacy skills to them.

Political campaigns are usually a combination of interpersonal and “Mass” communication with the expectation of positive outcomes by the political representatives. This study is an attempt to give an idea regarding respondent’s ability and trends of processing the political contents of Mass media. Elaboration Likelihood Model is taken as a framework for evaluating the content processing trends. A questionnaire comprising of two parts and consisting the cue list of central and peripheral notations commonly used by political representatives. A sample of 1032 young people was selected by using a combination of stratified and multistage cluster sampling techniques. Results of the study revealed that majority of the youth did not bother to process the political content by effortful cognition, rather they followed attractive slogans and political personalities. Moreover it was found that people used the same approach for decision making in favor of a political party as they use to hate the opponent parties.

Research was designed to evaluate the credibility perception of youth regarding different mainstream and new media sources of political news. This study adopted questionnaire survey method as a research design of the study. The sample was drawn using probability proportional to size (PPS) and random sampling techniques. For the purpose of investigation, 375 respondents from Higher Education Commission (HEC) of Pakistan’s approved universities/degree awarding institutions (DAIs) were selected for the purpose of data collection. The findings of the study revealed that in case the respondents are encountered with the conflicting version of political news stories, they considered traditional TV news channels and newspapers as first and second most credible political news sources respectively. Additionally, it was also found that the majority of the youth perceived live streaming of traditional TV news channels and news websites that are associated with the mainstream news sources (traditional TV news channels and newspapers) as first and second most credible online sources of political news respectively. Additionally, this research also found that the majority of the respondents considered non-governmental sources of political news as most credible. Overall, the study concluded that the respondents still perceived traditionally delivered political news as highly credible sources of political news.

Published: September 2020

At present, immunotherapy is successfully used for the treatment of multiple malignant diseases, especially in the late stages of metastatic tumors, which until now, were difficult to treat using standards protocols. Positive therapeutic effects of immunotherapy were demonstrated in treatment of many common oncological diseases. However, despite the expressed positive effect, in some patients immunotherapy can demonstrate non-typical forms of the answer. To establish accurate diagnosis it is necessary to know radiological manifestations of immune-related adverse events (irAE), mainly, immune-mediated pneumonitis, colitis, hypophysitis, hepatitis and myositis. Early identification and the corresponding treatment of irAE may improve patient's outcomes.

Insight into the Role of a Isophthalic Dihydrazide Derivative Containing Piperonylic Acid in Poly(L-lactide) Nucleation: Thermal Performances and Mechanical Properties
Authors: Huang Hao , Zhang Yan-Hua , Zhao Li-Sha , Luo Guang-Ming , Cai Yan-Hua
Published: September 2020

This work was aimed at synthesizing the N, N -isophthalic bis(piperonylic acid) dihydrazide (PAID) to be as a new crystallization accelerator for poly(L-lactide) (PLLA), and a detailed investigations of the non-isothermal crystallization, melting behavior, thermal decomposition behavior and mechanical properties of PLLA nucleated by PAID were performed applying differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and electronic tensile tester. The melt-crystallization proved that the PAID could act as a heterogeneous nucleating agent to significantly promote the crystallization in cooling, even the crystallization was still able to be accelerated upon the fast cooling at 50 oC/min. The final melt temperature was another crucial factor for PLLA�s melt crystallization, and when the final melt temperature was 170 oC, the onset crystallization temperature and melt-crystallization enthalpy was almost up to 150 oC and 56.8 J/g upon cooling of 1 oC/min, respectively. Furthermore, the chemical nucleation was proposed to be the nucleation mechanism of PAID for PLLA via the preliminary theoretical calculation. For the cold-crystallization, the addition of PAID exhibited an inhibition for the crystallization of PLLA, but the total crystallization process depended on the heating rate and PAID concentration. The single melting peak after cooling of 1 oC/min indicated that the crystallization had been thoroughly completed in cooling. Additionally, the single melting peak with different locations after full crystallization resulted from the different crystallization temperatures. A comparison in the onset decomposition temperature implied that the presence of PAID only slightly decreased the thermal stability of PLLA. The mechanical testing showed that, in contrast with the elongation at break, the existence of PAID enhanced the tensile strength of PLLA.

In the last two decades, both general and oral health status became more important for individuals, being associated to their quality of life, social provenance and income. Society�s evolution is associated to high expectations regarding edentulous and decays treatment. Metal filling such as gaudent or amalgam have been replaced by aesthetic materials, to achieve similarity to the patient�s genuine biological tissue. Along with the aesthetic demand, dental materials have to fulfill biocompatibility and mechanical properties proximate to healthy soft either hard tissues. Composite materials have the advantages of accomplishing biological and mechanical demands and to be accessible financially, compared to ceramics. Composites are classified according to the main monomer, filling, particles� dimension, addition of external molecules, this entirety having a direct influence on materials� properties. The objective of this prospective interventional in vitro study was to evaluate biomechanical properties of four different hybrid composites: Premise direct - Premise indirect (Kerr, Orange, California, USA), Gradia� Direct (GC, Alsip, Illinois, USA) and Ceramage� (SHOFU Dental, Ratinger, Germany). Vickers microhardness, compressive strenght, direct tensile strenght, water absorption and solubility were assessed. The results showed that microfilled hybrid composites UDMA (urethane dimethacrylate)-based monomer had the highest evaluations regarding Vickers microhardness, compressive strenght and tensile strenght, whereas water absorption was the highest for nanofilled hybrid Bis-GMA (bisphenol A-glycidyl methacrylate)/TEGDMA (triethylene glycol dimethacrylate), and solubility for microfilled hybrid UDMA based monomer.

The prognosis of the prosthetic rehabilitation is linked to the proper transfer of the clinical data to the dental laboratory, in the digital or conventional workflow. The aim of the present study was to compare the dimensional accuracy of analog and digitalized models, focusing on the influence of impression polymeric materials on the final digital model. Methods: The master model with standard reference points and the three groups of test models, obtained by alginic acid polymer impression (group A) and condensation-cured poly(dimethyl siloxane) in two impression techniques (1-step putty/light-body-group 1T, 2-steps putty/ light-body-group 2T), were measured in four standardized points before and after digitization. The differences from the master model and between the pair analog and digital models was calculated and statistically analysed using Mann-Whitney tests (2 groups), and one-way Anova (3 groups) with post-hoc Tukey s Test was applied for pairwise analysis (a;=0.05). Results: All analog and digitalized model tests showed altered dimensions from the master model. A general reduction of the digitalized models, in sagittal and transversal dimensions, was observed, comparing to the reference model. The impression material was a significant factor influencing dimensional accuracy. Conclusions: a statistically significant difference was found between most of the models and the master model. However, through digitalization, some of the errors were compensated. The digital models from alginic acid polymer group (group A) registered the highest trueness, with no statistically significant difference (P]0.05) from the reference model.

Published: September 2020

Rapid innovations in 3D printing technology have allowed highly complex parts to be manufactured quickly and easily, particularly for prototyping purposes. Fused Deposition Modeling of thermoplastic materials is one of the most commonly used techniques in three-dimensional (3D) printing. The major aim of Fused Deposition Modeling (FDM) is to design and manufacture usable parts for fields such as engineering and medicine. Therefore, it is essential to investigate the mechanical properties of such FDM processed structures. One of the most commonly used materials currently on the market is Polylactic Acid (PLA). The main purpose of this paper is to investigate the effects of aging and heat treatment on the tensile properties of PLA printed test specimens. The tensile properties of parts manufactured by the 3D printer are influenced by various parameters such as extrusion temperature, infill density, building direction, layer height, etc. A total of 96 specimens were built by altering building orientation and layer height to estimate and compare the tensile properties of the printed parts. To investigate the aging effect, 30 of 96 specimens were printed 6 months before the tensile experiment. Half of both aged and new specimens were cured in an oven at 57.5 [�ŞC] for 3 hours while the other half endured no heat treatment. After the performed measurement, it can be concluded that heat treatment generally improves structural strength of the printed parts, while aging decreases it. However, these effects are highly dependent on the layer thickness and printing quality. The tensile test is conducted according to the ASTM D638 standard. The fractured samples were further characterized using an electron microscope.

Published: September 2020

A series of four drug release formulations based on 5-fluorouracil encapsulated into a chitosan-based matrix were prepared by in situ hydrogelation with 3,7-dimethyl-2,6-octadienal. The formulations were investigated from structural and morphological aspects by FTIR spectroscopy, polarized light microscopy and scanning electron microscopy. It was established that 5-fluorouracil was anchored into the matrix as crystals, whose dimension varied as a function of the crosslinking density. The in vitro drug release simulated into a media mimicking the physiological environment revealed a progressive release of the 5-fluorouracil, in close interdependence with the crosslinking density. In the context of Pharmacokinetics behavioral analysis, a new mathematical procedure for describing drug release dynamics in polymer-drug complex system is proposed. Assuming that the dynamics of polymer-drug system�s structural units take place on continuous and nondifferentiable curves (multifractal curves), we show that in a one-dimensional hydrodynamic formalism of multifractal variables the drug release mechanism (Fickian diffusion, non-Fickian diffusion, etc) are given through synchronous dynamics at a differentiable and non-differentiable scale resolutions. Finally, the model is confirmed by the empirical data.

Published: September 2020

The development of 3D printing technologies has gained considerable momentum. Almost every technical-scientific field uses this technology. The technology of 3D printing thermoplastic materials (or fusible filaments - FFF), is based on the realization of the parts by depositing successive layers of extruded filament at temperatures corresponding to the viscous aggregation state. One of the research activities of the CERAS research center is the realization of collaborative drone systems, drones capable of moving in each of the three unstructured environments: aerial, terrestrial aquatic / underwater. This paper presents a study on the choice of the type of thermoplastic material, for making the structural elements (chassis) of an underwater Rover. The need for this study arose from the fact that the design and construction of underwater vehicles is generally demanding. The materials must be characterized by resistance to compression / stretching / shearing, as in underwater environments the existence of currents, pressures (with increasing depth of immersion). Also, the materials must be chemically neutral, because in aquatic environments we can find various chemicals spilled in water (intentional or not) and finally salinity.

Published: September 2020

In this study, five ultrafiltration membranes (polysulfone, cellulose acetate and polyethe-rsulfone) were tested in the treatment of aqueous protein solutions similar to wastewater from fermentation industries. The experiments were made in tangential flow filtration. The permeate flux for the five membranes tested at the optimum pressure of 3 bar decreased due to the effect of clogging the pores by the macromolecular protein solutions. Cellulose acetate membranes showed the lowest permeate flux (Ac-Cel1=152.4 L/m2.h and Ac-Cel2=40.3 L/m2.h) which doesn�t recommend them for the ultrafiltration process of bovine serum albumin. When a polysulfone membrane was used in several cycles of protein-containing wastewater ultrafiltration, the permeate flow decreased progressively from one cycle to another due to the internal clogging of the membrane (501.6 L/m2.h up to 444.0 L/m2.h). Regarding the ultrafiltration of protein solutions with a suspended yeast content, the clogging was predominant on the membrane�s surface, which results in a decrease of the permeate flux by over 50%.

Semi-structured one-on-one interviews were conducted, and transcripts analyzed for thematic content. Findings elucidated three emergent themes: change in classroom practices; change in personal and professional pursuits; and change in perceptions, beliefs, and attitudes. As a result of the experience, misconceptions were dispelled, new understandings of agriculture and natural resources were developed, confidence was increased, and a desire for more global engagement was communicated. Teachers expressed their desire to be more inclusive, encourage global engagement and citizenship among their students, and integrate more global concepts within their teaching practices. The findings have implications for the importance of holistic approaches to teacher development through international experiential learning, rather than just a focus on classroom teaching practices. To add to our findings, similar research with other teachers beyond second stage should be conducted. Also, research exploring the influence of international development activities on career commitment should be conducted.

Orta Çağ'da Yaşamış iki Alman Esirin Gözünden Osmanlı-Türk Toplumunda Sosyal Değerler
Authors: ÖZTÜRK Ali Osman
Published: September 2020

Johannes Schiltberger, 1394-1427 yılları arasında Türkiye, Suriye, Mısır, İran, Orta Asya ve Sibirya'da esir olarak yaşayıp gördüklerini “Türkler ve Tatarlar Arasında (1394-1427)” başlıklı kitabında yazıya geçirir. Çok değişik insan coğrafyalarında bulunmuş olmasından dolayı Schiltberger'in Türkleri insani özellikleri bakımından diğer halklarla karşılaştırma yoluna gideceğini varsayıyoruz. Hans Ulrich Krafft ise 24 Ağustos 1574 yılında borç yüzünden Osmanlı-Türk makamlarınca tutuklanır. 24 Ağustos 1577 yılında tahliye edilir ve memleketine dönmek üzere yola çıkar ve ancak 9 Aralık 1578'de vatanına kavuşur. Mesleği tacirlik olan H. U. Krafft'ın Osmanlı toplumunda geçerli ticaret ve ticari ilişkiler hakkında hassasiyeti olacağından, gözlemlerinde bunlara yer vereceğini düşünüyoruz. Bu makalede her iki Almanın anılarında İstanbul'un fethi öncesi ve sonra sosyal hayatta gözlemlenen değerler ve değer yargıları ele alınacaktır. Öncelikle sosyal, ahlaki, insani değerler her bir eserde tespit edilecek, sonra bunlar 150 yıllık süre bağlamında karşılaştırılarak Osmanlı-Türk Toplumunda değerler değişimi olup olmadığı ve var ise bunların olası nedenleri üzerinde duracağız.

Authors: İŞİGÜZEL Bahar
Published: September 2020

Was man schon weiß, gibt jedem die Stärke, weiter zu lernen und höhere Erfolgsziele zu erreichen. Im Tertiärsprachenunterricht ergreift der Lerner im Kontext Deutsch als Fremdsprache nach Englisch (DaFnE) günstige Lerngelegenheiten aus der ersten Fremdsprache Englisch. Durch die Sensibilisierung des Sprachvergleichs und der Bewusstmachung von Sprachlernerfahrungen, können Lernende mit ihren vorhandenen Sprachkenntnissen sichere Lernerfolge im DaF-Unterricht erzielen. Um den Input der Lernenden aus dem Englischen bewusst zu aktivieren, müssen optimale Lernsituationen bereitgestellt werden. In diesem Zusammenhang soll im Tertiärsprachenunterricht ein interkultureller Raum geschaffen werden, wo die Gemeinsamkeiten und Unterschiede zwischen dem Englischen und Deutschen bearbeitet werden können. Die Redewendungen können als soziokulturelle Kompetenz zu der Integrierung in den DaFnE-Unterricht bedeutend sein. Diese Arbeit konzentriert sich auf die Einbeziehung der Redewendungen in den Tertiärsprachenunterricht. Die englischen und deutschen Redewendungen wurden für den DaFnE-Unterricht analysiert und als Redewendungen mit absoluter Ähnlichkeit, Redewendungen mit teilweiser Ähnlichkeit und Redewendungen mit kontextueller Ähnlichkeit kategorisiert. Nach der Bestimmung der Redewendungen für den Tertiärsprachenunterricht DaFnE, war es wichtig, wie man diese Redewendungen als DaF-Lehrkraft im Tertiärsprachenunterricht in die Praxis umsetzen kann. Dazu wurden einige Einbeziehungswege mit Beispielen vorgeschlagen. Die Visualisierung der Redewendungen kann die Lehrkraft besonders beim Anfangsniveau effektiv einsetzen und damit einen wichtigen Antrieb zur Erweiterung des Wortschatzes geben. Die anderen zwei Einbeziehungsmöglichkeiten auf der Spur der Redewendungen und Kontextsituationen der Redewendungen können in weiteren Niveaus eingesetzt werden, nachdem sich die Lernenden an die Redewendungen gewöhnt haben. Mit dem interkulturellen Vergleich der Redewendungen können Lernmotivation, Sprachbewusstheit und zugleich Lernerautonomie gefördert werden.

Rasonalitas yang dibangun oleh konsepsi homo islamicus berpandangan bahwasegenap tindakan ekonomi tidak hanya menuruti hasrat-hasrat alamiah manusia tetapi harusdidasarkan kepada kebenaran dan kebajikan. Jalan untuk mencapai rasionalitas ini tidak lainadalah mensubordinatkan motif, pikiran, orientasi, kehendak dan perilau ekonomi kepada aturandan moralitas yang ditentukan oleh syariat Islam.
