This research aims to analyze the impact of the United States policy of pressure and sanctions on changing Iran's conduct. Since the Islamic Revolution of Iran in 1979, the US has continuously pursued various policies towards Iran, aiming to change the regime by force or isolate it politically and economically. The main research question lies in the following: To what extent does the US pressure policy and its sanctions affect the conduct Iran?. This research discusses that the more there are economic and political alternatives to Iran, the more it will be challenging the US demands. Moreover, the more the US pursues a negotiating policy based on mutual interests, the more Iran will positively respond to American demands.

Background: Hydatid disease remains an important & challenging medical problem.
Case report: A62 year old male patient was admitted complaining of upper abdominal discomfort. Six days earlier he suffered from acute pain in the right upper quadrant, mild systemic allergic manifestation, a fever of 38.5oC and chills. He was managed by a new surgical approach of myoplasty of the right hemidiaphragm combined with preoperative decompression of the bile duct by an endoscopic sphincterotomy. A case search identified study describing rupture of a hydatid cyst of the hepatic dome into biliary tract. The incidence of intrabiliary rupture of hepatic hydatid cysts is 25% in patients treated with external surgical

In this paper, an exact stiffness matrix and fixed-end load vector for nonprismatic beams having parabolic varying depth are derived. The principle of strain energy is used in the derivation of the stiffness matrix.
The effect of both shear deformation and the coupling between axial force and the bending moment are considered in the derivation of stiffness matrix. The fixed-end load vector for elements under uniformly distributed or concentrated loads is also derived. The correctness of the derived matrices is verified by numerical examples. It is found that the coupling effect between axial force and bending moment is significant for elements having axial end restraint. It was found that the decrease in bending moment was
in the

In this study, the induced splined shaft teeth contact and bending stresses have been investigated numerically using finite element method(Ansys package version 11.0) with changing the most effecting design parameter,(pressure angle, teeth number, fillet radius and normal module), for internal and external splined shaft. Experimental work has been achieved using two dimensional photoelastic techniques to get the contact and bending stresses; the used material is Bakelite sheet type “PSM-4”.
The results of numerical stress analysis indicate that, the increasing of the pressure angle and fillet radius decrease the bending stress and increase the contact stress for both internal and external spline shaft teeth while the increasing of

Scorpions and spiders belong to the class Arachnida in phylum Arthropoda. Scorpions are easily distinguished by median eyes on obvious the center of the carapace and have one pair, and lateral eyes have 2-8 in some species. Scorpions do not have good eyesight so the median eyes have always been simple and they are more sensitive than the lateral pairs. They have anterior median eyes (AME) with narrow field of view and pairs of lateral eyes (LE) with more sensitivity and response to light. Family Buthidae have 2-6 lateral eyes in Compsobuthus Mesobuthus, Hottentotta, while Vaejovidae, Chactidae and Chaerilidae have 2 pairs of lateral eyes. In addition, 3 pairs are found in Orthochirus and Androctonus. Spiders have six eyes in family Pholicid

The artistic dimension appears as an important factor in urban townscape's identity shaping, as many cities in the world have a different identity through the different artistic elements in it, the artistic dimension is meant within the research (set of artistic elements that can contribute to urban identity shaping, whether on architecture or on urban design in addition to public, urban arts). Many previous global studies have dealt with one type or more of art affecting the urban townscape identity of specific cities as a case study. Thus, we can diagnose the research problem as (the lack of local knowledge about the role of the artistic dimension in all its components in achieving the urban townscape identity), and th

This research deals with the review of former research that made to solve the challenges and complexities of both static and dynamic soil structure interaction through discussing advanced computational models and their applications and exploring methods of solving the challenges of soil structure interaction in foundation engineering to provide a guide for the engineering community through the complexes of soil structure interaction. It was found that the numerical analysis for both static and dynamic soil structure interaction using the finite element method with the aid of advanced computional models is ideal for dealing with the non-linearity of soil and structure properties and loading conditions and that the use of

The seismic design of pile foundations mainly relies on analyzing the seismic response of layered, liquefiable locations. Two design scenarios are taken into consideration from the case histories; the first is how pile foundations react to the stresses and lateral displacements brought on by the lateral dispersion of liquefied soil. The second is how to piles reaction to seismic activity that occurs with the development of high pore water pressures. The PLAXIS 3D software is utilized in this research with a non-linear soil constitutive model (hypoplastic model) for both dry and saturated loose sandy soils under the impact of two earthquakes and the motion of different features to give a complete understanding of the dyna

A field study was performed in the Agricultural Machines and Equipment Department, Agriculture College, Basrah University, to study the effect of the operating pressure and nozzle height on droplet properties reaching to the target using knapsack sprayer with a maximum capacity of 16l. A nozzle is mounted on the rod of sprayer. Three different operating pressures were tested in this study of 1, 1.7, 2 bar and three different nozzle heights of 50, 70, 90cm. Brilliant Sulpho-Flavinedye was used to measure mean droplet sizes, droplet densities, droplets number, and relative span factor deposited on white card papers. The spray properties were determined after spraying in field and then were analyzed using Image J software. The main

This study was aimed to identify the obstacles that facing cereal farmers that applying the agricultural practices to decrease the effects of climate variation phenomenon in the central region of Iraq. This research was conducted on cereal farmers at Baghdad, Najaf, Babil, and Wasit which were the most cultivated governorates of cereal crops (wheat, rice, and yellow corn). A randomized sample of (227) farmers was taken, that represents 0.25% of the total cereal farmers in the four governorates (90,584 farmers). In order to achieve the research goal, a questionnaire was prepared to collect data related to the research topic, for which a four-way scale was designed (33) paragraphs, and this field included three axe

Stripping is one of the major distresses within asphalt concrete pavements caused due to penetration of water within the interface of asphalt-aggregate matrix. In this work, one grade of asphalt cement (40-50) was mixed with variable percentages of three types of additives (fly ash, fumed silica, and phosphogypsum) to obtained an modified asphalt cement to resist the effect of stripping phenomena .The specimens have been tested for physical properties according to AASHTO. The surface free energy has been measured by using two methods namely, the wilhelmy technique and the Sessile drop method according to NCHRP-104
procedures. Samples of asphalt concrete using different asphalt cement and modified asphalt cement percentages(4.1,4.6 an
