The expansion and growth of cities is a remarkable phenomenon in urban planning literature,so that unpredictable developments have become more evident in recent decades, especially in cities that haveundergone changes in their physical structure following the promotion of their political role. The present paper seeksto identify the factors driving growth in the developed areas of Ardebil city a...

We show how to find a decomposition of the edge set of the complete graph into regular factors where the degree and edge-connectivity of each factor is given. Let t, n, k1, k2, . . . , kt, l1, l2, . . . , lt be nonnegative integers such that ∑ i ki = n− 1, if n is odd then each ki is even, and for 1 ≤ i ≤ t, li ≤ ki and li = 0 if ki = 1. We shall show how to find a factorization of Kn that cont...

p27Kip1 is a cyclin-dependent kinase inhibitor that negatively regulates cell proliferation by mediating cell cycle arrest in G1. This study was undertaken to assess the prognostic value of p27Kip1 for astrocytomas. Tissue samples from 130 astrocytomas (WHO grade 1, 5 cases; grade 2, 23 cases; grade 3, 64 cases; grade 4, 38 cases), including 92 primary and 38 recurrent tumors, were examined imm...

Organic agriculture (OA) includes a comprehensive production management system that is considered as one of the strategies to reduce negative impacts of industrial agriculture in many countries. This research was identifying factors affecting the development of OA in Ardabil province. A descriptive– correlation survey approach was used in this study. Participants were agricultural specialists o...

The aim of the present study was to systematically examine the variations of the effects of (1) transitional anxiety states and enduring anxiety dispositions, and (2) worldviews (hierarchic, egalitarian, individualist, and fatalist), as a function of the type of hazard considered. Ten risk factors were identified. Transitional anxiety contributed significantly to the prediction of four of these...

Three-body breakup cross sections and analyzing powers for the Li, Li, Be and C(~ p, pα) reactions were measured at an incident energy of 296 MeV. Data were analyzed using the plane wave impulse approximation (PWIA) and the distorted wave impulse approximation (DWIA) and compared with previous studies. DWIA calculations reproduce shapes of projected spectra and analyzing power distributions fai...

and school staff. therefore, it is essential to pay continuous and specific attention to safety problems in schools. we identified 20 critical success factors (csfs) in the current study based on previous researches in order to achieve effective school safety. then these factors validated by 33 governmental high school administrators. this survey was conducted in tehran, among 96 governmental h...

Determined whether six commonly used inventories which are associated with suicide (Hopelessness Scale, Zung Self-Rating Depression Scale, Scale for Suicide Ideation, Reasons for Living Inventory, Suicide Probability Scale, and the Suicide Ideation Questionnaire) overlap; all six were given to 308 undergraduates. A principal components factor analysis yielded four factors with Eigenvalues great...

Zygophyllum atriplicoides is one of the important species of Iran rangelands that has special importance owing to some properties like high distribution rate, coverage percentage, density, and plant biomass that make it possible to supply a part of forage needed by livestock during spring and winter as well as to avoid soil degradation against water and wind erosions. This research tries to stu...
