Abstract
Studies in the field of learning and organization have changed through formation of the concept of a learning organization. As a result various models have been developed and customized for project based organizations. Still, they have not yet been customized for Project Based Organizations, as a very important category of organizations with growing importance. The special requirements of project based organizations in learning demands the development of a special model for project based learning organizations (PBLOs). This is routed in the temporary nature of projects. This study aims to develop a paradigmatic model for PBLOs based on case studies in two project based organizations of oil and gas industries. The strategy of the study is structured grounded theory and the data are acquired from interviewing 20 participants in the field of project and knowledge management. As a result of the interviews and by analysis and coding of 715 obtained phrases, 25 basic concepts were identified which have been placed in the paradigmatic model. Since a qualitative approach towards organizational learning has been very limited up till now, and in addition no studies have yet addressed PBLOs in particular, this work could be treated as a pioneering study in the field.

Abstract
In this book, Ebrahimi tells the story of a love, rooted in the childhood friendship of two people and flourished at the young age, and the book once again describes the city I loved. This relationship owes more to space than to time. In human societies, the city is known as the center of events, and Ebrahimichr('39')s story takes place in a city that, at first glance, bears no resemblance to the city that will be narrated later. This can be examined and analyzed from the point of view of thematic critique and literary geography, which believes that it narrates the inside out. In this study, we use the theory of Michel Collot to see the transformation of the city that changes with the narrator / hero, and the reson of this change is in the characterchr('39')s life. In fact, this method makes it easy to study the geography of the text, access and comprehend the world of the text, but at the end we will see that the city is active and present like a hero and can be considered as one of the principle characters.

Abstract
One of the objectives of structuralist criticism - based on linguistics - is to analyze the formation of texts from literature. In this descriptive and analytical study, The authors took advantage of a semasiological approach to the study of the text in order to enrich The analysis of textual structures. By the semasiological approach It means the study of meanings which consists in starting from words, from forms to go towards the determination of meaning.
The purpose of this research is to present a structural analysis of a corpus of contemporary Persian literature. The problematic of this research consists of knowing how meaning takes its configuration by means of the text structures of the story "Some credible stories about love" by Mostafa Mastour. Mastour was born in 1964 in Ahvaz. He wrote his first stories before his thirtieth birthday. He has a particular penchant for physics and geometry in his writings. The corpus in the present research is the first story in a Short story collection composed of seven short stories entitled "Some credible stories", published in 2003.
The methodological novelty of this study comes from the fact that in the analysis a semasiological approach was taken into account with regard to confrontation of the famous dichotomy: meaning/form.
The main hypothesis of this research consists of believing that the structural system of text analysis follows a logic and a movement that goes from microstructures to macrostructures, from particles of forms to the semantic whole.
The result of this article demonstrated how meaning takes shape in text, from a semasiological point of view, where the analysis of structures and forms (lexicon, phonetics, grammar and narration) of the corpus gives us access to the main theme and the overall meaning of the story, namely love.

Abstract
One of the most famous hydraulic phenomena to reduce flow energy is hydraulic jump, which is used downstream of dam overflows in river sections and structures established in irrigation and drainage canals. It is very important to control and reduce the kinetic energy resulting from this phenomenon at smaller distances from the place of formation. Among the examples of depreciation structures, we can mention the roughness of the bed and the construction of stilling basin and making expansion, but it must be said that it causes pressure fluctuations and damage to the bed of the canals and river. The existence of the submerged jet can reduce this pressure fluctuation and change the flow downstream to subcritical. The purpose of this research was to investigate the presence of a submerged jet system on the characteristic of asymmetric hydraulic jump in corrugated beds so that this phenomenon can be controlled and ensure the safety of structures and beds downstream. For this reason, the experiments were carried out in a flume with a fixed peak overflow with a central flow rate range of 26 to 67 liters per second and 3 mutual submerged jet flow rates. This investigation showed that the corrugated bed in the region of gradual expansion has reduced the length of the jump compared to its absence and the changes in the flow depth have also decreased. Also, the impact of the opposite jet in the submerged shape improved this process; So that energy consumption was reduced by 25-30% and jump length by 50%. Therefore, the effective role of this combination of jet system and continuous corrugated bed was shown.
