Epoxy composites reinforced with multi-walled carbon nanotube/poly(ethylene glycol)methylether-coated aramid fiber
Authors: Kausar Ayesha , Siddiq Muhammad 
Published: November 2015

Abstract
A novel type of aramid fibers coated with poly(ethylene glycol) methyl ether (PEGME)-modified multi-walled carbon nanotubes (MWCNTs) was designed using electrophoresis. Owing to the good interaction of MWCNT-PEGME with the matrix, the coated fibers were well dispersed in epoxy resin. Thin films of epoxy/aramid-MWCNT-PEGME were prepared by placing the modified aramid fibers in molds, and the epoxy resin was infused into them. 4,4′-Diaminodiphenylmethane was dissolved in epoxy before the resin was poured over the aramid fibers coated with MWCNT-PEGME. According to fracture surface studies, the modified fibers were completely miscible with the epoxy resin and the filler was dispersed well in the space between the aramid fibers. The tensile strength of neat resin was increased from 658 to 1198 MPa in 40 wt.% of fiber-loaded epoxy/aramid-MWCNT-PEGME 40 composite. The maximum flexural strength was also found to be higher for epoxy/aramid-MWCNT-PEGME 40 (1593 MPa). The glass transition temperature (T
g) was studied using differential scanning calorimetry, in the range of 164–173°C. The tensile strength, modulus, flexural strength, and T
g of epoxy/aramid fiber composites with unmodified fibers were found to be lower than those of epoxy/aramid-MWCNT-PEGME composites.
An Investigation of the Linkage between Relationship Status (Single vs. Partnered), Identity Dimensions and Self-construals in a Sample of Polish Young Adults
Authors: Adamczyk Katarzyna , Luyckx Koen 
Published: November 2015

Abstract
The aim of this exploratory cross-sectional study was to examine the associations among relationship status, identity processes, and self-construals among Polish young adults.
The theoretical framework of the study consisted of Erikson’s psychosocial theory of human development (Erikson, 1963; 1968; 1980), the dual-cycle model of identity formation (Luyckx, Goossens, & Soenens, 2006), and the concept of independent and interdependent self-construals. A total of 291 university students (155 females and 136 males) aged 20-25 completed the Dimensions of Identity Development Scale (DIDS; Luyckx, Schwartz et al., 2008) (Polish adaptation - Brzezińska & Piotrowski, 2010a) and Self-Construal Scale (SCS; Singelis, 1994) (Polish adaptation - Pilarska, 2014). Results showed that single individuals scored higher on exploration in breadth, exploration in depth, and ruminative exploration, and lower on commitment making and identification with commitment than did partnered individuals. Further, single and partnered individuals did not differ in the area of independent and interdependent self-construals. Discriminant function analysis revealed that especially ruminative exploration and exploration in breadth were important variables for discriminating single from partnered status.
The Stratified Significance of a Historic Façade as a Basis for a more Durable Conservation Approach
Authors: Van Roy Nathalie , Van Balen Koen , Verstrynge Els , Naldini Silvia 
Published: November 2015

Abstract
In heritage conservation, a gap is often observed between the theory of conservation as a durable process that aims at the preservation of a historic building and the practice of restoration as a single intervention that aims at a fast and convincing result. This paper describes the proposed approach for the conservation of the main façade of the Shoemakers Chapel (in Dutch: Schoenmakerskapel) in Antwerp (Belgium), a listed monument since 1976. It serves as an example of how to develop a durable and realistic approach for the conservation of a sixteenth century façade. The basis for the conservation approach is the understanding that each intervention should take the stratified significance of the historic façade into account. In this paper, it will be shown how to combine a study of the façade from a technical point of view with an analysis of the façade as a carrier of cultural significance.
Combining Mineral and Polymer Binder Material Science for Sustainability in Construction and Restoration
Authors: Van Gemert Dionys , Cizer Özlem 
Published: November 2015

Abstract
The study of microstructure formation in polymer-cement concrete provides opportunities to exploit synergetic actions between cement and polymer, leading to performance improvement and to a wide range of new and innovative properties and applications. Polymers can reduce the impact of construction industry on environment, by decreasing the carbon footprint of cement and concrete production. Renovation and restoration, largely figuring in the concept of sustainable construction development, thank their growing share in construction activity to the input of polymers in repair and binder materials and in rehabilitation procedures. The study of ancient binders and mortars reveals aspects of the origins of the observed long lasting durability of those ancient mortars. It also reveals the interaction mechanisms between carbonation of air hardening components and hydration of hydraulic components, which in turn helps to develop chemical activation methods (i.e. alkaline activation) to improve the hydraulic properties of pozzolans and industrial residues to develop inorganic polymers (i.e. geopolymers) for eventually full replacement of cement in binders.
A tale about Zen philosophy and a motorcycle (that is: OER & MOOC quality)
Authors: Ghislandi Patrizia 
Published: November 2015

Abstract
The paper introduces the concept of education quality, mainly based on a shared culture, that is a background for a permanent reflection on a process in which teachers, students, and stakeholders are involved, in a gradual improvement of their competence. People can achieve quality if they head for an open, participatory, iterative trajectory towards personal identity construction through the achievement of satisfaction of a well done work. In this context measurement tools and final quality controls are only a means “toward the end of satisfying the peace of mind of those responsible for the work” (Pirsig, first edition 1974, 2005, p.304).
The also describes the Open Educational Resources and Massive Open Online Courses phenomenon, and presents the most recent studies about the theoretical framework and practical tools available in the scientific literature to scaffold the quality evaluation of open education. The discussion, taking full advantage of the literature presented, recognises that we are still in the infancy of the Open Education quality evaluation, and that the available tools have still to demonstrate their value in the application's fields, through empirical researches.
Disagreement, Cognitive Command, and the Indexicality of Moral Truth
Authors: Reichardt Bastian 
Published: November 2015

Abstract
Moral Relativism can be considered an attractive alternative to realism because relativists can make good sense of cultural and societal disagreements by seeing them as faultless. However, we can show that this advantage is made possible by systematically disagreeing with moral phenomenology. Relativists make a substantial distinction between intercultural and intracultural discourses which turns out to be incoherent. This can be shown by making use of Crispin Wright’s notion of Cognitive Command.

Abstract
Two new polyacetylenes (1 and 2), along with two known C-30 steroids (3 and 4) were identified from the Red Sea sponge, Xestospongia sp. The chemical structures were determined based on extensive spectroscopic measurements 1D (1H, 13C and DEPT) and 2D (COSY, HSQC and HMBC) NMR, UV, IR and MS. The new compounds 1 and 2 were evaluated for their antimicrobial and antitumor activities. 1 and 2 were active against multidrug- resistant bacteria with MICs ranged from 2.2 to 4.5 μM. No toxicity was recorded for the two tested compounds up to 5 μM using Artemia salina as a test organism. Compound 2 showed excellent antifungal activity against some pathogenic fungi such as Aspergillus niger and Candida albicans (MIC 2.2–2.5 μM) and antitumor activity against both Ehrlich ascites carcinoma and lymphocytic leukemia (LD50 5.0 μM).

Published: November 2015

The construction of hydroelectric power stations can affect the fauna, including the adaptation to the new lentic conditions, and may lead to the disappearance of some species and the colonization of others. Usually, there is a lack of information in the post-flooding phases. The present study is a preliminary qualitative survey of mammals, birds, and reptiles in the influenced area of the Balbina hydroelectric dam (01°55' S, 59°29' W). Species records were made during field trips to the reservoir with no group specific methods. The conservation status of the identified species followed the classification adopted by IUCN. Twenty-two mammals (one endangered – EN), forty-two birds and six reptiles (one vulnerable – VU) were identified. Although the list presented here is preliminary, if appropriately complemented, it can be used to understand the effects of hydroelectric dams on the Amazonian fauna.
Zakat as an Instrument of Eradicating Poverty (Indonesian Case)
Authors: Athoillah Mohamad Anton 
Published: November 2015

This paper describes more clearly about the charity as an instrument of poverty alleviation. Said to be more pronounced because zakat is not only described from the aspect of Islamic law, but also from the aspect of Islamic Economics. Starting from the idea of a content analysis of two professors of Economic Development, Prahalad and Yuyun Wirasasmita, this paper reveals the fundamental aspects of the causes of poverty, namely culture, alienation and exploitation. In this paper, the charity manages to pack in a comprehensive manner to a complementary instrument, whether Islamic law, and even Islamic Economics. Among the novelties in this paper is a substantive interpretation of zakat which is connected with the theory of economic development, compared with tax and economic-mathematical analysis to find a charity to further its position in the study of economics. As for other things that were outlined in this paper is the normative aspects of zakat, as where made explicit, as an instrument of poverty alleviation for various sectors, as seen from its usability goals.
Caracterização de minerais pesados e avaliação da radioatividade natural em sedimentos praiais de Acaú, Carne de Vaca e Ponta de Pedras, litoral norte do estado de Pernambuco
Authors: França Patrícia Pereira de , Valença Lúcia Maria Mafra , Souza Neto João Adauto de 
Published: November 2015

Os minerais pesados são assim denominados em razão de sua maior densidade em relação aos minerais comuns. O peso específico desses minerais é maior que dos feldspatos e do quartzo, cujos valores são de aproximadamente 2,6 g/cm3. São oriundos de rochas ígneas, metamórficas ou sedimentares e tendem a se concentrar nas praias em áreas de erosão. Este estudo tem por objetivo caracterizar os minerais pesados que se acumularam nos sedimentos praiais da área estuarina do Rio Goiana nos trechos ao sul (Carne de Vaca e Ponta de Pedras, Estado de Pernambuco) e ao norte (Acaú, Estado da Paraíba), bem como avaliar a radioatividade natural desses sedimentos, dado o fato que potencialmente alguns desses minerais possuem elementos radioativos. Os minerais pesados identificados (com percentual de abundância relativa) nas três praias foram Ilmenita, Zircão, Turmalina e Cianita. Outros ocorrem em determinas praias como o Epidoto em Ponta de Pedras e Rutilo em Carne de Vaca. Os valores da radioatividade natural medida in situ foram maiores em Ponta de Pedras chegando a medir 300-350 cps e o menores valores em Acaú. Do ponto de vista das fontes indicadas pelas assembleias de minerais pesados, pode se dizer que alguns dos minerais investigados são de origem ígnea e responsáveis pela radioatividade natural, como o Zircão e o Xenotímio já que esses apresentaram elementos como U e Th em sua composição.
