From "problematic” foreigners to "unproblematic” Muslims: Bosnians in the Swiss Islam-discourse

This article discusses the role of religion amongst the Bosnian Diaspora in Switzerland. In order to analyse this issue, it makes a distinction between the Bosnian working migrants who have lived in Switzerland since the 1970s and the Bosnian war refugees who found asylum in Switzerland from the mid-1990s onward. Despite the distinction, the issue of ‘Refugees and religion' and the issue of ‘Migration and religion' will overlap. The main argument of this contribution lays stress on the changing role in the meaning of religious orientation within a group of migrants. Taking the example of the Bosnian Diaspora in Switzerland, this contribution demonstrates that refugees and migrants are not simply transferring their religion as a fixed recipe for the solution of daily problems in their changed circumstances. Very often different discourses, internal and external, and new constructs influence and contribute to give religion a new meaning. While emphasis on practice of religious and ritual conventions give migrants a cultural and religious continuity, new interpretations of religious norms and directives can also produce changes and polarizations within the same ethnic group and same religious communit

Diophantine equations involving the bi-periodic Fibonacci and Lucas sequences

In this paper, we present new identities involving the biperiodic Fibonacci and Lucas sequences. Then we solve completely some quadratic Diophantine equations involving the bi-periodic Fibonacci and Lucas sequences

A New Hybrid Cryptosystem Involving DNA,Rabin, One Time Pad and Fiestel

Information security is a crucial need in the modern world. Data security is a real concern, and many customers and organizations need to protect their sensitive information from unauthorized parties and attackers. In previous years, numerous cryptographic schemes have been proposed. DNA cryptography is a new and developing field that combines the computational and biological worlds. DNA cryptography is intriguing due to its high storage capacity, secure data transport, and massive parallel computing. In this paper, a new combination is proposed that offers good security by combining DNA, the Rabin algorithm, one time pad, and a structure inspired by Fiestel. This algorithm employs two keys. The first key is a DNA OTP key which is used for only one secure communication session. The second key, which combines the public and private keys, is a Rabin key. Additionally, by using a Feistel inspired scheme and randomness provided by DNA, the ciphertext is made harder to obtain without the private key.Comment: 11 page

Indium-Mediated Cleavage of the Trityl Group from Protected 1H-Tetrazoles

On treatment with indium metal in MeOH–THF, trityl groups undergo reductive removal from 1H-protected tetrazoles (including aliphatic, aromatic, and heteroaromatic substituents), affording the corresponding free tetrazoles in excellent yields, without any decomposition of the tetrazole ring or reduction of any other group.This work was financially supported by the A.N.D.R.S (Agence Nationale pour le Développement de la Recherche en Santé) (Algérie), the Ministerio de Ciencia e Innovación of Spain (CTQ2011-24165, Consolider Ingenio 2010 CSD2007-00006), The Generalitat Valenciana (PROMETEO/2009/039, PROMETEOII/ 2014/017 and FEDER).

Zn/MeOH-Mediated Practical and Easy Detritylation of Protected 1-Trityltetrazoles

A practical and low-cost method for the detritylation of 1-titryltetrazoles using zinc and methanol is described. This procedure is versatile and efficient in the deprotection of several protected tetrazoles bearing aliphatic, aromatic, and heteroaromatic substituents, as well as some functional groups, without decomposition of the tetrazole ring.This work was financially supported by the Agence National pour le Développement de la Research en Santé (Algérie) and the Spanish Ministerio de Ciencia e Innovación (CTQ2011-24155, CTQ2011-24165), the Ministerio de Economía y Competitividad (CTQ2013-43446-P, CTQ2014-51912-REDC, CTQ2014-53695-P), FEDER, the Generalitat Valenciana (PROMETEO 2009/039, PROMETEOII/2014/017), and the University of Alicante.
