On Artin's braid group and polyconvexity in the calculus of variations
No full textLet Ω ⊂ 2 be a bounded Lipschitz domain and let
F : Ω × 2×2
+
−→
be a Carathèodory integrand such that F (x, ·) is polyconvex for L2-a.e. x ∈ Ω. Moreover assume that
F is bounded from below and satisfies the condition F (x, ξ) ∞ as det ξ 0 for L2-a.e. x ∈ Ω. The paper describes the effect of domain topology on the existence and multiplicity of strong local minimizers of the functional
[u] :=
Ω
F (x,∇u (x)) dx,
where the map u lies in the Sobolev space W1,p
id (Ω,2) with p 2 and satisfies the pointwise condition
det ∇u (x) > 0 for L2-a.e. x ∈ Ω. The question is settled by establishing that [·] admits a set of strong
local minimizers on W1,p id (Ω,2) that can be indexed by the group n ⊕ n, the direct sum of Artin’s pure braid group on n strings and n copies of the infinite cyclic group. The dependence on the domain topology is through the number of holes n in Ω and the different mechanisms that give rise to such local minimizers are fully exploited by this particular representation

The Purpose of Practicing Faradarmani Treatment; An Iranian Complementary and Alternative Medicine
No full textAbstract“Faradarmani”, a newly introduced Iranian complementary and alternative treatment (founded by Mohammad Ali Taheri) is based on the theory of “Common Consciousness of the Parts”. As a qualitative complementary method of treatment, Faradarmani takes action to improve the condition of the patient without any kind of intervention in the quantitative process of treatment and without any hardware manipulation (treatments applied physically such as pharmaceutical, invasive & surgical, physiotherapy, massage therapy, or any other similar method in which utensils and devices are to be implemented). Faradarmani can be considered in treating various kinds of physical, psycheal and mental diseases. It is aimed to reach the following objectives: (1) Practical acquaintance with the Interuniversal Consciousness (Divine Intelligence) and practical theology, (2) Becoming free from being captive of ‘Self, (3) To attain practical worship, (4) Recognition of the inner treasure, (5) Providing a way for public salvation

RETRACTED: Numerical modeling of hydraulic fracture propagation: Accounting for the effect of stresses on the interaction between hydraulic and parallel natural fractures
No full textThis article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of According to EGYJP committee’s decision and after precise investigation ,It is ultimately obvious that the article titled: “Numerical Modeling of Hydraulic Fracture Propagation: Accounting for the Effect of Stresses on The Interaction Between Hydraulic and Parallel Natural Fractures” by its auther Jaber Taheri Shakib is totally plagiarized from the thesis titled: “Analysis of hydraulic fracture propagation in fractured reservoirs: an improved model for the interaction between induced and natural fractures” by Arash Dahi Taleghani; http://hdl.handle.net/2152/18381; beginning from the abstract passing through chapter 3. Even the conclusion of chapter 3 is copied directly from the thesis: “Analysis of hydraulic fracture propagation in fractured reservoirs: an improved model for the interaction between induced and natural fractures” A matter which leads the committee to take its final decision of retracting the mentioned article from volume no. 22 issue 4 and blacklisting its author Dr. Jaber Taheri Shakib from our journal. Hoping that this decision is taken promptly from your honored side
Characterization and stabilization of an unstable railway cut slope in marl - A case study
No full textLandslides and Society: Integrated Science, Engineering, Management, and Mitigation.
Conference Proceedings in published (book) form and on CD-ROM, as well as a conference program with abstractsThis paper presents a study of railway cut slope instability at Northeast of Iran. In 1996 the failure occurred at eastern side of the trench, after a long raining period. The trench has been cut in marl, with a well defined weathering profile, from unweathered at depth, to fully weathered at the ground surface. In order to determine the shear strength parameters of the failed ground mass, some back analyses of the failed slope were performed, using a limit equilibrium method by means of CLARA scientific software. By this, the relationship between cohesion and friction angle and also the most probable shear strength values were found. In addition, the change of marly layer with depth was made clear. The main designed stabilization method is, to construct a number of lime columns inside the slide mass and a lime wall at the toe of the unstable slope. The desired configuration of the lime columns was determined by performing some stability analysis, using Finite Element Method by means of PLAXIS 7.2 software. These analyses demonstrate that, by constructing lime columns at 20×20 m grid, the safety factor of the unstable mass will be increased from 1.10 to 1.36 in short-term period, and to 1.50 in long-term period.Abbas Taheri, Ali Taheri, K.

Cultural consumption, interactive sociality and the museum
No full textWithin marketing and consumer behaviour research, museums have been generally conceptualised as public consumption spaces where visitors benefit from a variety of affective, recreational, and cognitive experiences. As such, the social context has been largely subordinated to enhancing visitors’ cultural consumption experience in the physical environment of the museum. Our study takes a reverse path by highlighting how the cultural consumption experience in the museum nourishes ‘interactive sociality’ both inside and outside the museum. The analysis of our qualitative data (interpretive individual and group interviews and non-participatory observations) on Kelvingrove Museum and Art Gallery in Glasgow (UK) imply that by leveraging interactive sociality, managers can enhance the museum’s value proposition and societal worth in contemporary society. The paper critiques museum studies’ over-reliance on (social) psychology theories and demonstrates the value of adopting alternative (socio-cultural) approaches to the advancement of theory in the field. It provides evidence for the fact that cultural consumers’ interaction with(in) the organisation is not confined to the physical boundaries of a given context. People extend their varying experiences and sensibilities to other domains beyond the museum walls
