DRILLING MUD IS AN IMPORTANT FLUID IN DRILLING OPERATIONS AND IS DIRECTLY RELATED TO DRILLING PROBLEMS. IF THE DRILLING MUD DOES NOT HAVE THE PROPER PROPERTIES, IT WOULD BE DIFFICULT TO DRILL IN THE DRILLING OPERATION. THUS, THE NEED TO USE FLUIDS LIMITING OPERATIONAL PROBLEMS, AND IMPROVING DRILLING AND SAVING TIME AND MONEY IS CLEARLY FELT. MOREOVER, TODAY THE PHENOMENON OF FLUID-LOSS OF DRILLING INTO CRACKED FORMATIONS HAS BECOME A MAJOR CHALLENGE FOR THE DRILLING INDUSTRY. HEAVY COSTS SUCH AS LOSS OF DRILLING TIME, EXCESSIVE CONSUMPTION OF MATERIALS, UNPROFESSIONAL CONTROL TECHNIQUES AND LOW PRODUCTIVITY ARE OF THE PROBLEMS NEEDED TO COPE WITH THIS PROBLEM. THE STUDY TYPE IS APPLIED AND DESCRIPTIVE-ANALYTIC REGARDING RESEARCH METHOD CONDUCTED IN CASE STUDY DESIGN. DATA COLLECTION METHOD IS DOCUMENTATION AND LIBRARY STUDY. THE STUDY FIRST EXPLAINED THE TYPES OF DRILLING MUD AND ITS ADDITIVES AND ITS IMPACT ON DRILLING QUALITY. THEN, IT WAS CONCLUDED THAT KNOWING THE TYPE OF DRILLING FLUID AND ITS ADDITIVES AND ITS CHOICE TO REDUCE THE COST OF DRILLING AND INCREASE THE EFFICIENCY HAVE A GREAT IMPACT ON THE DRILLING QUALITY. MOREOVER, THE EFFECT OF POLYMER ADDITIVES, NANOCOMPOSITES AND INDUSTRIAL POWDERS ON THE REDUCTION OF LOSS WAS INVESTIGATED SHOWING THAT THE ADDITION OF NANOCOMPOSITES AND POLYMERIC MATERIALS REDUCES THE THICKNESS OF SLUDGING AND FLUID LOSS AND ALSO INCREASES THE VISCOSITY OF DRILLING MUD AND CAN BE VERY EFFECTIVE IN INCREASING PRODUCTIVITY AND REDUCING COSTS.

ONE OF THE METHODS TO FIND OUT THE AMOUNT OF TECTONIC AND SEISMIC ACTIVITIES IN A REGION IS THE USE OF MORPHOMETRIC METHODS. THE JAGIN RIVER IS LOCATED IN HORMOZGAN PROVINCE AND IN THE CITY OF JASK AND ORIGINATE FROM THE BASHAGARD MOUNTAINS AND BY JOINING SEVERAL OTHER RIVERS SUCH AS THE ANGAHRAN RIVER FLOWS INTO THE OMAN SEA. GEOGRAPHICALLY, IT IS CONSIDERED A PART OF MAKRAN. THE JAGIN RIVER ORIGINATES FROM THE SOUTHERN SLOPES OF BASHAGARD MOUNTAINS AND THEN PASSES THROUGH THE STRAIT OF MARANG AND JOINS ANOTHER MAJOR BRANCH OF SHARIFI TO THE OMAN SEA, AND THIS AREA HAS MANY ACTIVE FAULTS. THE MOVEMENT OF THE RIVER IS AFFECTED BY THE ACTIVITY OF THESE FAULTS. THEREFORE, IN THIS STUDY, BY CALCULATING THE TECTONIC ACTIVITY OF THE AREA, IT HAS BEEN ATTEMPTED TO REDUCE THE RISKS OF THE EARTHQUAKE, CONSIDERING THE FACT THAT THE DAM WAS BUILT ON THE RIVER. THE ACTIVE BASINS IN THE AREA HAS ALSO BEEN CHARACTERIZED. IN THIS STUDY, TO OBTAIN SEISMIC ACTIVITY IN THE STUDIED AREA, THE FOLLOWING INDICATORS HAVE BEEN USED: 1) DRAINAGE ASYMMETRY INDEX, 2) TOPOGRAPHIC DEGRADATION, 3) VALLEY WIDTH TO VALLEY HEIGHT,. DUE TO THE EARTHQUAKES OCCURRING IN THE AREA AND THE STUDY OF THESE INDICATORS, IT CAN BE CONCLUDED THAT MOST OF THE BASINS HAVE RELATIVELY HIGH TECTONIC LEVELS, AMONG WHICH BASINS 1, 21, 25 AND 30 HAVE MORE ACTIVITY THAN OTHER BASINS AND THE TECTONIC PROCESS OF THE AREA IS CONTROLLED BY ITS FAULT. AMONG THE FAULTS MENTIONED, THE JAGIN AND ASHKAN FAULTS ARE MORE ACTIVE THAN THE OTHER FAULTS IN THE REGION.

THE IDENTITY OF A COMMUNITY AND ITS COLLECTIVE MEMORY ARE NOT ONLY REPRODUCED BY MEANS OF LITERATURE, RELIGIOUS RITUALS, CEREMONIES AND NATIONAL CELEBRATIONS AND SPORTS COMPETITIONS, BUT ALSO URBAN SPACE THROUGH THE PLACE OF MEMORY AND THE SPACES OF EXPERIENCE AND PRACTICE, THE FIELD OF REINFORCEMENT AND THE CONTINUITY OF COLLECTIVE IDENTITY. THE MAIN PURPOSE OF THIS STUDY IS TO STUDY THE PLACE OF MEMORY AS ONE OF THE FACTORS INFLUENCING THE FORMATION, CONTINUITY AND STRENGTHENING OF COLLECTIVE IDENTITY.THE PRESENT STUDY IS BASED ON THE SURVEY AND ITS POPULATION CONSISTS OF ALL 15-YEAR-OLDS ABOVE CITIZENS OF ISFAHAN CITY WHO HAVE A LONG HISTORY OF LIVING IN THE CITY AND HAVE ENOUGH LIVING EXPERIENCE TO ANSWER THE RESEARCH QUESTIONS. THE SAMPLE SIZE OF THE STUDY WAS 650 INDIVIDUALS. THEY WERE SUBJECTED TO QUOTA SAMPLING AND QUESTIONNAIRES. IT WAS OBSERVED BASED ON THE FINDINGS THAT, THE HISTORICAL PLACES OF ISFAHAN, SUCH AS NAGHSHE JAHAN SQUARE, SI-O-SE POL BRIDGE AND KHAJU BRIDGE, WITH GREAT DISPARITY AS THE THREE PLACES OF THE MAIN MEMORY OF CITIZENS, IN WHICH PEOPLE HAVE EXPERIENCE AND MEMORY OF THE PAST. IT IS INTERESTING TO NOTE THAT THE RESULTS OF THESE SITES ARE SHOWN FOR DIFFERENT AGE GROUPS, AND ALMOST ALL AGE GROUPS PLACE THEIR FIRST MEMORY IN ISFAHAN HISTORICAL PLACES. THIS CONJUNCTION BETWEEN DIFFERENT GENERATIONS REFLECTS THE ROLE OF THE PLACE OF MEMORY AND URBAN SPACE IN THE REPRODUCTION OF COLLECTIVE IDENTITY.

IN RECENT DECADES, STUDYING THE RELATIONSHIP BETWEEN "CLASS" AND DIFFERENT DIMENSIONS OF URBAN LIFE HAS BEEN ONE OF THE IMPORTANT ISSUES IN THE FIELD OF URBAN STUDIES. THE MAIN PURPOSE OF THIS STUDY IS TO EXPLAIN THE PATTERN OF URBAN SPACE CONSUMPTION UNDER THE CLASS VARIABLE. THE PRESENT STUDY WAS QUALITATIVE AND THE SAMPLES WERE STUDIED BASED ON THEORETICAL SAMPLING AND PHENOMENAL INTERVIEWS. THE TECHNIQUE OF INTERVIEWING ANALYSIS WAS BASED ON THE SEVEN-LEVEL COLAIZZI METHOD. THE INNOVATION OF THE PRESENT RESEARCH IS TO APPLY THE PIERRE BOURDIEU ANALYSIS MODEL TO THE RELATIONSHIP BETWEEN TYPES OF CAPITAL AND TASTES AND CLASS CONSUMPTION IN PATTERNS ANALYSIS OF URBAN SPACE CONSUMPTION.A FOUR-DIMENSIONAL TYPOLOGY OF CLASS SPACE USAGE WAS OBTAINED, BY CODING, CATEGORIZING AND ANALYZING INTERVIEWS. WITH REGARD TO THE COMBINATION OF VARIOUS CULTURAL AND ECONOMIC CAPITALS, FOUR TYPES OF CONSUMPTION "PURPOSEFUL", "INTRICATE", "FLUID", AND "AGGRESSIVE" WERE DISTINGUISHED. IT WAS FOUND THAT HOLDERS OF LOW LEVELS OF ECONOMIC AND CULTURAL CAPITAL WERE MORE AGGRESSIVE IN THEIR CONSUMPTION PATTERNS AND WERE STRUGGLING TO ABSORB URBAN SPACE AND OUTER SPACE AND IMPOSE THEIR PRESENCE ON SPACE. CONVERSELY, THE NEW MIDDLE CLASSES ARE MORE ALIGNED WITH SPACE, AND THEIR CONSUMPTION PATTERN IS CALLED "FLUID". THE MEMBERS OF THE HIGHER CLASSES, ESPECIALLY THOSE WITH A HIGH DEGREE OF ECONOMIC CAPITAL OTHER THAN CULTURAL CAPITAL, ARE MORE INCLINED, MOVING FROM URBAN SPACE TO INTERIOR SPACE AND BUILDING PRIVATE SPACE AND SPACE ENTHUSIASM. IN CONTRAST, FOR PEOPLE WITH HIGH LEVELS OF CULTURAL CAPITAL, TARGETED CONSUMPTION OF SPACE IS THE PATTERN OF THEIR CONSUMPTION.

THE ESTABLISHMENT AND FORMING OF CITIES, VILLAGES AND AREAS WHICH ARE SUSTAINABLE IN TERMS OF ECONOMY, ENVIRONMENT AND SOCIETY WHICH HAVE THE ABILITY TO FIGHT CHALLENGES SUCH AS POPULATION GROWTH, MIGRATION, AND CLIMATE CHANGE IS CONSIDERED ONE OF THE MOST DIFFICULT RESPONSIBILITIES OF THIS CENTURY. SOCIAL SUSTAINABILITY HAS BEEN SOMEWHAT OVERLOOKED AS ONE OF THE THREE BASIC COMPONENTS OF SUSTAINABILITY WITHIN SUSTAINABLE DEVELOPMENT ISSUES WITH PRIORITY GOING TO ECONOMIC AND ENVIRONMENTAL ISSUES. SOCIAL SUSTAINABILITY REFERS TO THE WAY IN WHICH PEOPLE, NEIGHBORHOODS AND COMMUNITIES INTERACT AND LIVE TOGETHER FOR THE SAME PURPOSE. (COLANTONIO & DIXON, 2009). IN REALITY, SOCIAL SUSTAINABILITY COMBINES THE DESIGN OF THE PUBLIC ARENA WITH THE SOCIAL REALM AND LOOKS FOR THE INFRASTRUCTURE THAT WILL SUPPORT SOCIAL, CULTURAL AND PUBLIC LIFE AND THE DEVELOPMENT OF PLACES FOR HUMAN EVOLUTION. SCHOOL AS THE MAIN FOUNDATION FOR THE DESIGN AND FORMATION OF NEIGHBORHOODS WILL BE USED IN THIS RESEARCH, INTRODUCING A STRATEGY FOR DEVELOPING A PLACE FOR HUMAN EVOLUTION WITH AN INCREASING LEVEL OF INTERACTION AND POPULAR PARTICIPATION IN THE FORM OF A UNIFIED EDUCATIONAL PROGRAM WHICH INCLUDES ALL SECTIONS. THE PRESENT STUDY USES A DESCRIPTIVE-ANALYTIC METHOD TO DESCRIBE THE STATUS OF SOCIAL SCHOOLS IN THE FORMATION OF SOCIAL SUSTAINABILITY AND BY PRESENTING A PROPOSAL FOR THE DESIGN OF SOCIAL SCHOOLS AS A LEARNING COMPLEX TO PROVIDE A SAMPLE IN THE CITY OF BAHARESTAN IN ISFAHAN.

ESTIMATION OF FLOW DISTRIBUTION IN RIVERS FOR OPTIMUM MANAGEMENT AND OPERATION, FLOOD MANAGEMENT AND IMPLEMENTATION OF WATERSHED MANAGEMENT PROJECTS IS VERY IMPORTANT. IN RECENT DECADES, THE APPLICATION OF ENTROPY THEORY HAS BEEN EXPANDED TO SPEED DISTRIBUTION IN OPEN CHANNELS. THE RATIO BETWEEN MEAN AND MAXIMUM VELOCITY IN A RIVER SECTION IS ALWAYS CONSTANT, AND IT CAN BE CALCULATED BASED ON THE ENTROPY PARAMETER. IN THIS RESEARCH, USING THE RENI ENTROPY THEORY, AN EQUATION FOR A ONE DIMENSIONAL VELOCITY PROFILE IN OPEN HINGES WAS DEVELOPED AND ITS ACCURACY WAS STUDIED USING LABORATORY DATA. THE RESULTS OF THIS STUDY SHOWED THAT THE MAXIMUM VALUE OF ROOT MEAN SQUARE ERROR IS 0.035, WHICH INDICATES THE ACCURACY OF THIS METHOD. IN THIS METHOD, IT IS POSSIBLE TO ESTIMATE THE VELOCITY DISTRIBUTION BY IDENTIFYING THE ENTROPY PARAMETERS AND TAKING THE MAXIMUM VELOCITY AT A CROSS SECTION.

MORPHOMETRIC METHODS ARE AMONG METHODS TO FIND THE QUANTITY OF GEOLOGICAL AND SEISMICITY SITTING. THE AREA IS LOCATED IN THE NORTH OF IRANSHAHR BETWEEN MAKRAN, EAST IRAN BELT AND CENTRAL IRAN. KARVANDAR-DAMAN BASIN AREA IS AN ACTIVE BASIN AND HAS SEISMICITY POTENTIAL. TECTONIC ACTIVITY IS AFFECTED BY MAJOR FAULTS OF THE AREA. TO ASSESS TECTONIC ACTIVITIES IN THE AREA, WE HAVE ANALYZED GEOMORPHIC INDICES INCLUDING: THE DRAINAGE BASIN ASYMMETRY (AF), TRANSVERSE TOPOGRAPHIC SYMMETRY FACTOR (T), VALLEY FLOOR WIDTH-VALLEY HEIGHT RATIO (VF), AND MOUNTAIN-FRONT SINUOSITY (SMF). THE RESULTS ARE CONSISTENT WITH FIELD OBSERVATIONS AND GEOLOGICAL STUDIES ON LANDFORMS AND THE REGIONS WITH HIGH RELATIVE TECTONIC ACTIVITY SHOW THE GEOLOGICAL ACTIVITY IN AREAS NO.1 ARE MORE THAN OTHERS AND MOST EARTHQUAKES HAVE HAPPENED IN THIS AREA.

NOWADAYS THE TREND OF URBAN CONSERVATION AND RESTORATION EVOLUTION FROM RECONSTRUCTION TO RENOVATION OF A CITY HAS LED TO URBAN REGENERATION. THE REGENERATION APPROACH WITH A COMPREHENSIVE VIEW TOWARD THE CITY IS AN ATTEMPT TO DEVELOP THE CITY INTERNALLY BY CONSIDERING ALL POTENTIALS OF THAT CITY. IN THIS RESPECT, CULTURE AND APPLICATION OF CULTURAL CAPITAL AS A WAY TO URBAN REGENERATION LEAD TO UNIQUE CITIES WITH AN INDEPENDENT AND COMPETITIVE IDENTITY. ON THE OTHER HAND, THE CONCEPT OF THE ECONOMY OF A CREATIVE CITY RELIES ON KNOWLEDGE, ART AND CULTURE WHICH IS CAPABLE OF ECONOMICAL DEVELOPMENT OF THE CITY VIA THE CULTURE-BASED REGENERATION. THE UNESCO CREATIVE CITIES NETWORK, WHICH HAVE BEEN DEVELOPED TO HELP RESTORE SOCIO-ECONOMIC POTENTIALS AND CREATIVE CULTURAL INDUSTRIES, OBTAINED CONSIDERABLE SUCCESS DURING THE RECENT DECADE. FURTHERMORE, THIS STUDY TRIES TO EVALUATE THE STRATEGIES APPLIED IN UNESCO CREATIVE CITIES NETWORK IN ORDER TO FIND OUT SUCCESSFUL STRATEGIES FOR URBAN REGENERATION. THEN, IN THIS STUDY AN ANALYTICAL-DESCRIPTIVE METHOD BASED ON DATA GATHERED FROM DOCUMENTS AND LIBRARIES, EXPERIENCES AND STRATEGIES OF 115 OF UNESCO CREATIVE CITIES WERE ANALYZED. FINDINGS INDICATE THAT THE MOST IMPORTANT STRATEGIES OF UNESCO CREATIVE CITIES IN SOCIO-ECONOMIC RETRIEVAL OF A CITY ARE AS FOLLOWS: INVESTING ON THE COMPARATIVE ADVANTAGE OF CITY'S ART, KNOWLEDGE AND CULTURE, DEVELOPING ART AND CULTURE MARKET, IDENTIFYING THE CITY'S POTENTIALS BY ORGANIZING VALUABLE INTERNATIONAL FESTIVALS AND EVENTS, APPLYING VARIOUS SYMBOLIC POTENTIALS OF THE CITY, USING ART AND CULTURE FOR THE SOCIAL REFORM AND COHESION AND INCREASING OF SOCIAL CAPITAL, AS WELL AS APPLYING EDUCATIONAL AND SCIENTIFIC POTENTIALS TO ENCOURAGE ART AND ITS MARKET.

THE MAIN OBJECTIVE OF THIS STUDY IS TO IDENTIFY THE APPROPRIATE METHOD FOR ORGANIZING THE WORN OUT TEXTURE OF SHEIKH ALI KHAN NEIGHBORHOOD. THE TYPE OF THIS RESEARCH IS APPLIED AND THE RESEARCH METHOD IS DOCUMENTARY-ANALYTIC SURVEY. FOR THIS PURPOSE, BASED ON DOCUMENTATION, OBSERVATION, PERCEPTION AND QUALITATIVE ANALYSIS OF SWOT, THE DECISION OF THE MULTI-CRITERIA FUZZY TOPSIS HAS BEEN USED AND FINALLY FOR ACCESS THE MOST RELIABLE WAY TO ORGANIZE THE WORN OUT TEXTURE OF SHEIKH ALI KHAN NEIGHBORHOOD IS THROUGH DELPHI TECHNIQUE IN THREE STEPS. THE EXCEL SOFTWARE WAS USED TO ANALYZE THE DATA AND EXAMINE THE VARIABLES AND ARC GIS SOFTWARE WAS USED TO PREPARE THE MAPS. ACCORDING TO THE FINDINGS, "THE ABUNDANCE OF RELIGIOUS CENTERS, THE MOSQUE, PEDIGREE, THE EXISTENCE OF A PARKING LOT, " THE BEST OF STRENGTHS, "THE PROBLEMS OF GARBAGE COLLECTION, THE LACK OF GREEN SPACE, OCCUPATIONAL AND OCCUPATIONAL PLACES DISTURBING, ACCESS TO THE STATION AND THE TRAP OF TRAFFIC JAMS AND THE STREETS "AS THE HIGHEST WEAKNESSES, THE BHUTAN INDUSTRIAL GROUP AND THE MASSOUD COMMERCIAL COMPLEX" HAVE BEEN IDENTIFIED AS THE HIGHEST THREAT AS THE GREATEST OPPORTUNITY AND "BRINGING THE NEIGHBORHOOD YOUTH TO UNHEALTHY AMUSEMENTS AND THE LACK OF SPACE FOR SPORTING AND CULTURAL ACTIVITIES" AS THE HIGHEST THREAT.. ALSO ACCORDING TO THE DELPHI METHODOLOGY, MODERNIZATION IS CONSIDERED AS A SUITABLE STRATEGY FOR THE MANAGEMENT OF THE AGED AREA OF THE NEIGHBORHOOD. SHEIKH ALI KHAN IS KNOWN.
