In Qajar era, the importance of commercial function of Mazandaran province to sovereignty was considerable due to its position. In fact, Mazandaran had a strategic position for government regarding two reasons; the first reason is that it was the nearest rich province to Tehran _capital of Iran_ in foodstuffs production and second one is that the closest trade link of Tehran to Caspian Sea, which was the route of Iran\'s trade with Russia _ the largest trading partner of Iran– passed through this province. Moreover, Mazandaran had a comparative advantage in the production of some exported crude stuffs such as rice, cotton, silk and wood. Consequently, the expansion of Mazandaran roads could be considered an important factor in developing of economy in the local, regional and national scales.\nIn Naser al-Din Shah Period, Despite of all political, economic and geographical difficulties in expanding of Mazandaran\'s roads, government decided to spend an huge capital in the expansion of Larijan road considering the protection of political and economic security of the capital city according to a number of preliminary studies conducted by a group of engineers on three available routes including Hezar CHam, Larijan and Savad Kuh. \nThe present research endeavors to investigate the effects of road construction programs of Naser al-Din Shah on the trade of Mazandaran province based on statistical data and using diagrams with descriptive-analytical approach. The outcomes of this research reveal not only the substantial role of road construction in increasing of exports and imports of Mazandaran province but also its impact on Mazandaran\'s commercial changes such as the increase of commercial caravansaries and the growth of markets of Bar forush, Sari and Ashraf cites.
Aim: \nThis study aimed to evaluate the duration of cyst inactivation after percutaneous treatment of hepatic hydatid disease and the factors that may affect this process.\nMaterial and Methods:\nUltrasound follow-up records were evaluated, and the criteria of cyst inactivation were determined. Cyst type, cyst size, and localization were listed after the scanning of pre-treatment ultrasound reports. Percutaneous treatment technique, aspirated cyst content, complications, and duration of catheterization were listed. The duration from percutaneous treatment to cyst inactivation was defined as inactivation time. Ultrasound follow-up period, cyst size at the last follow-up, and inactivation time were recorded. \nResults: \nA total of 116 patient data were included in the study. The mean follow-up period after treatment was 1003.95±293.23 days. The mean inactivation time was 420.99±221.18 days. The size of the inactivated cysts decreased significantly compared to the pre-treatment cyst size (p=0.001). There was a positive correlation between cyst size and duration of catheterization (p=0.0001). The inactivation time decreased with increased duration of catheterization (p=0.001). There was a significant decrease in the inactivation time of patients who presented with complications (p=0.008). \nConclusion: \nPatients who develop complications after percutaneous treatment and patients with longer catheterization exhibit shorter cyst inactivation.
As it is known the equation Aϕ=f with injective compact operator has a unique solution for all f in the range R(A).Unfortunately, the right-hand side f is never known exactly, so we can take an approximate data f_{δ} and used the perturbed problem αϕ+Aϕ=f_{δ} where the solution ϕ_{αδ} depends continuously on the data f_{δ}, and the bounded inverse operator (αI+A)⁻¹ approximates the unbounded operator A⁻¹ but not stable. In this work we obtain the convergence of the approximate solution of ϕ_{αδ} of the perturbed equation to the exact solution ϕ of initial equation provided α tends to zero with (δ/(√α)).
Kaneko studied the poly-Bernoulli polynomials which are defined by using the polylogarithm functions. In this paper, we study the degenerate poly-Bernoulli polynomials and numbers arising from polyexponential functions, and derive their explicit expressions and some identity involving them.
The inconsistency in prioritized knowledge base is because the assertions (ABoxes) come from several sources with different levels of reliability. We introduce the handling of this inconsistency problem to query inconsistent DL-Lite knowledge bases. Most of the approaches, studied in the literature, firstly repair the set of the inconsistent assertions of the DL-Lite’s inconsistent knowledge base and then interrogate it. In this paper, we proceed directly with an interrogation of the knowledge base to recover an exhaustive list of answers and then to repair these answers. This paper investigates several query answering strategies from multiple datasets using a recurring function that calculates the rank of coherence in order to manage the inconsistencies in the set of responses. We study these strategies from different points of view: productivity, precision, recall, F-mesure and computational complexity. The experimental study as\nwell as the analysis of the results, which we carried out, showed that our approach is much more productive than those studied since it provides the greatest number of answers while remaining the best in execution time. The computational complexity analysis shows that our approach is achieved in polynomial time. The experiments, carried out on different corpora, show encouraging results in productivity and running time compared to other approaches in the literature.
