INVESTIGATION OF CURRENT SOIL AND WATER ISSUES IN ARID AND SEMI-ARID REGIONS IS OF GREAT IMPORTANCE FOR SUSTAINABLE SOIL WATER MANAGEMENT. THE EXISTENCE OF DIFFERENT SOLID COMPOSITIONS SUCH AS CALCIUM CARBONATE AND GYPSUM IN THESE SOILS, LARGELY INFLUENCE THEIR HYDRAULIC CHARACTERISTICS. THESE HYDRAULIC PROPERTIES HAVE DIRECT EFFECT ON MAINTAINING SOIL WATER CONTENT. DIRECT MEASUREMENT OF SOIL HYDRAULIC PROPERTIES INCLUDING RETENTION CURVE AND UNSATURATED HYDRAULIC CONDUCTIVITY IS EXPENSIVE AND TIME CONSUMING. AN ALTERNATIVE FOR DIRECT MEASUREMENT IS THEN THE USE OF INDIRECT METHODS TO PREDICT THE SOIL HYDRAULIC FUNCTIONS. ONE PROMISING INDIRECT METHOD IN THIS REGARD IS TO DERIVE THE SO-CALLED PEDO-TRANSFER FUNCTIONS (PTFS). THE OBJECTIVE OF THIS STUDY WAS TO STUDY THE INFLUENCE OF SOIL CALCIUM CARBONATE ON WATER RETENTION CURVE, USING THE DERIVED PTFS. CONSEQUENTLY, 50 CALCAREOUS SOIL SAMPLES WERE RANDOMLY TAKEN FROM GARMSAR REAGION, IRAN. THE SOIL ARTICLE SIZE DISTRIBUTIONS WITH AND WITHOUT CALCIUM CARBONATE, BULK DENSITY AND CALCIUM CARBONATE CONTENTS WERE MEASURED AND USED TO DERIVE THE REQUIRED PTFS AT MATRIC POTENTIALS OF 0, 33, 50, 100, 300, 500 AND 1500 KPA. THE RESULTS INDICATED THAT THE CALCIUM CARBONATE CONTENT IS THE MOST IMPORTANT DOMINANT PARAMETER TO PREDICT THE WATER RETENTION CURVE FOR CALCAREOUS SOILS.

THE K -NEAREST NEIGHBOR (K -NN) ALGORITHM IS ONE OF THE TRADITIONAL METHODS THAT IS USED IN CLASSIFICATION. IT ASSIGNS AN UNSEEN POINT TO THE DOMINANT CLASS BETWEEN ITS K NEAREST NEIGHBORS WITHIN THE DATA SET. HOWEVER, LACK OF A FORMAL FRAMEWORK FOR SELECTING THE NUMBER OF THE NEIGHBORHOOD K IS PROBLEMATIC. THIS ARTICLE INVESTIGATES A NEW METHOD FOR CALCULATING THE OPTIMUM VALUE OF K USING CROSS-VALIDATION TECHNIQUES. THE PROPOSED METHOD IS ALSO FULLY AUTOMATIC WITH NO USER-SET PARAMETERS. THE PROPOSED METHOD IS TESTED ON DIFFERENT BENCHMARK DATA SETS WITH HIGH CLASSIFICATION ACCURACY RATE. THE AUTHORS COMPARED RESULTS WITH OTHER METHODS AND THE PROPOSED METHOD SHOWED 0.1% - 4% HIGHER CLASSIFICATION ACCURACY RATE THAN OTHER METHODS.

THE BUILT ENVIRONMENT AND CONSEQUENTLY VEHICULAR TRANSPORT HAS A SIGNIFICANT IMPACT ON PUBLIC HEALTH AND ENVIRONMENTAL QUALITY. ALSO VEHICULAR TRANSPORT AS AN IMPACT OF BUILT ENVIRONMENT IS ONE OF THE MOST IMPORTANT SOURCE FOR ENVIRONMENTAL DECAY SUCH AS NOISE POLLUTION IN CITY CENTERS. SO, ONE OF THE TRANSPORT SCHEMES LIKE PEDESTRIANIZATION CAN HAVE A SIGNIFICANT IMPACT ON ENVIRONMENTAL QUALITY AND IMPROVE NOISE POLLUTION CONDITION. THIS PAPER SHOWS, TO WHAT EXTENT THE BUILT ENVIRONMENT AND IMPLEMENTATION OF PEDETRIANIZATION SCHEME HAS INFLUENCE ON REDUCING NOISE POLLUTION LEVEL AT TEHRAN’ CITY CENTER.THE HIGH DENSITY LAND DEVELOPMENT, LAND USE MIX, CONNECTED STREET NETWORKS AND RETAIL FLOOR AREA RATIO CAN PROMOTE PHYSICAL ACTIVITY AND DECREASE EMISSIONS OF AIR POLLUTANTS. BUT ALSO INCREASED COMPACTNESS, CAN INCREASE TRAFFIC CONGESTION AND EXPOSURE OF HARMFUL EMISSIONS WITHIN CENTRAL AREAS AND INCREASE NOISE POLLUTION LEVEL. BUILT ENVIRONMENT CAN REDUCE TRIP RATES, THROUGH THREE PRINCIPAL DIMENSIONS, DENSITY, LAND USE DIVERSITY AND PEDESTRIAN-ORIENTED DESIGNS AND ENCOURAGE PEOPLE TO NON-AUTO TRAVEL WHICH THIS FINALLY LEAD TO INCREASE WALKABILITY AND REDUCE AIR AND NOISE POLLUTION. THEREFORE, STRATEGIES TO PROMOTE AIR QUALITY IN CITY CENTERS ARE REQUIRED TO ENABLE LARGER HEALTH BENEFITS.THE RESULTS OF THE SURVEY SUGGEST THAT THE IMPLEMENTATION OF PEDESTRIANISATION IN TEHRAN'S CITY CENTER HAS BEEN VERY SUCCESSFUL; ENVIRONMENTAL CONDITIONS AND PEDESTRIAN SAFETY HAVE IMPROVED CONSIDERABLY. AS A RESULT WAS FOUNDED AN INCREASE IN WALKABILITY TO BE ASSOCIATED WITH AN INCREASE IN TIME SPENT IN PHYSICALLY ACTIVE TRAVEL, FEWER VEHICLE MILES TRAVELED, FEWER LEVEL OF NOISE POLLUTION.

INFECTIOUS BRONCHITIS IS A CONTAGIOUS RESPIRATORY DISEASE CAUSED BY INFECTIOUS BRONCHITIS VIRUS (IBV). ONE OF THE STRUCTURAL PROTEINS OF THE VIRUS IS S1 PROTEIN WHICH IS VERY VARIABLE AND ITS VARIETY CONTRIBUTING TO POOR CROSS-PROTECTION BETWEEN SEROTYPES CAUSES THE NEED FOR VACCINE DEVELOPMENT USING THE PREVALENT SEROTYPE IN A GIVEN REGION WHICH COULD BE TIME-CONSUMING AND EXPENSIVE PROTOCOL. DUE TO THE TIME-CONSUMING NATURE OF LIVE ATTENUATED VACCINE DEVELOPMENT PROCESS, IN THE CURRENT STUDY WE TRIED TO INTRODUCE SOME LINEAR B-CELL EPITOPES FOR THE S1 SUBUNIT BELONGING TO STRAIN CK/CH/LSD/110311 ATTAINED FROM NCBI WITH THE HOPE THAT IT COULD COMBAT WITH ONE OR SOME SPECIFIC SEROTYPES OF IBV AS EPITOPE VACCINE. EPITOPE PREDICTION WAS CARRIED OUT USING SOME OF THE MOST IMPORTANT FEATURES OF PROTEINS INCLUDING ANTIGENICITY AND PHYSICOCHEMICAL PROPERTIES (HYDROPATHY, FLEXIBILITY AND ACCESSIBILITY) THROUGH DIFFERENT ONLINE SOFTWARES. FINALLY EIGHT UNIVERSAL LINEAR B-CELL EPITOPES OF THE S1 PROTEIN OF IBV WERE INTRODUCED.

IN THIS PAPER WE PRESENT A QUANTUM MECHANICAL STUDY OF A CIRCULAR AND STADIUM BILLIARD. BY USING THE GYRATION RADIUS WE STUDY CHAOS IN CIRCULAR AND STADIUM BILLIARD. IN QUANTUM THE COORDINATE OF THE COLLISION ZEROS OF WAVE FUNCTION ON THE BOUNDARY OF BILLIARD ARE USED FOR CALCULATE THE GYRATION RADIUS. THEN WE ANALYZE THE RESULTS OBTAINED IN QUANTUM BILLIARDS.

TO EVALUATE THE EFFECT OF SIX COMBINED HORMONES AND VITAMINS AS TREATMENTS ON SOME OF TRAITS IN POTATOES CULTIVAR (AGRIA), AN EXPERIMENT WAS CONDUCTED IN 2014-2015 IN A RANDOMIZED COMPLETE BLOCK DESIGN WITH THREE REPLICATIONS IN LABORATORY CONDITION. LINEAR AND QUADRATIC REGRESSION ANALYSIS SHOWED THAT BETWEEN THE TWO EVALUATED TRAITS (Y=MAIN SHOOT LENGTH, X=NUMBER OF SECONDARY SHOOT) THERE WAS A SIGNIFICANT RELATIONSHIP AS FOLLOWS: Y=75.278-2.087X AND Y=76.546-2.699X+0.061X2. THE ABOVE EQUATION SHOWS THAT BY INCREASING THE NUMBER OF SECONDARY SHOOT, MAIN SHOOT LENGTH DECREASES. LINEAR AND THIRD DEGREE REGRESSION ANALYSIS SHOWED THAT BETWEEN THE TWO EVALUATED TRAITS (Y=THE MAXIMUM OF SECONDARY SHOOT LENGTH, X=NUMBER OF SECONDARY SHOOT) THERE WAS A SIGNIFICANT RELATIONSHIP AS FOLLOWS: Y=11.621-0.571X AND Y=4.179+5.816X-1.295X2-0.074X3.THE ABOVE EQUATION SHOWS THAT BY INCREASING THE NUMBER OF SECONDARY SHOOT, THE MAXIMUM OF SECONDARY SHOOT LENGTH DECREASES. QUADRATIC REGRESSION ANALYSIS SHOWED THAT BETWEEN THE TWO EVALUATED TRAITS (Y=THE MAXIMUM OF SECONDARY SHOOT LENGTH, X=NUMBER OF SECONDARY SHOOT) THERE IS NO SIGNIFICANT RELATIONSHIP AS...

THIS PAPER INVESTIGATES THE ELECTRONIC PROPERTIES OF HYDROGENATED SILICON CARBIDE NANO SHEET BASED ON THE DENSITY FUNCTIONAL THEORY (DFT). ALL CALCULATIONS HAVE BEEN PERFORMED USING A PLANE-WAVE BASED PSEUDOPOTENTIAL METHOD. FIRST OF ALL, WE' VE SIMULATE OUR HEXAGONAL NANOSHEET OF SIC. THEN, WE' VE TRIED DIFFERENT POSITIONS FOR HYDROGEN ADSORPTION. FOUR DIFFERENT POSITIONS OF ADSORPTIONS ARE CONSIDERED IN THIS PAPER AND IT IS SHOWN THAT THE MOST STABLE STATE HAPPENS WHEN HYDROGEN ATOMS ARE ADSORBED ON SILICON AND CARBON ATOMS AT THE TWO OPPOSITE SIDES OF SILICON CARBIDE HEXAGONAL NANO SHEET. THIS ADSORPTION HAVE MADE SOME CHANGES IN THE ATOMS POSITIONS SO THAT THE NANO SHEET DIDN’T REMAIN FLAT ANY MORE. THE RESULTS HAVE SHOWN THAT THIS STRUCTURE WAS THE MOST STABLE ONE AMONG THOSE FOUR, WITH A TOTAL ENERGY ABOUT -346.12 RY. SILICON CARBIDE IS A SEMICONDUCTOR WITH A WIDE BAND GAP ABOUT 2.5851 EV. AFTER THE HYDROGEN ADSORPTION, THE HYDROGENATED SILICON CARBIDE NANO SHEET HAVE HAS A BAND GAP ABOUT 3.9499 EV, WHICH IS MUCH MORE THAN THE BAND GAP IN THE PURE STRUCTURE.

CLOUD COMPUTING IS NOW AN IMPORTANT PART OF IT ENTERPRISE. IN RECENT YEARS, ORGANIZATIONS SUCH AS BANKS, HOSPITALS, MEDICAL CENTERS ETC. HAVE STARTED TO RELY ON CLOUD SERVICES. BUT THERE ARE CHALLENGES IN THE USE OF CLOUD COMPUTING, SUCH AS ENSURING THE RELIABILITY, DATA INTEGRITY AND SO ON. ENSURING DATA INTEGRITY AND SECURITY, WHILE SETUP COST IS OPTIMAL, IS ONE OF THE MOST IMPORTANT CHALLENGES. IN THIS PAPER, WE PROPOSE A FAST AND SECURE METHOD TO CREATE AND EVALUATE DIGITAL SIGNATURES. OUR METHOD (E-ECDSA) IS BASED ON ELLIPTIC CURVE DIGITAL SIGNATURE ALGORITHM AND IS A COMPLEMENT TO IT. IN PARTICULAR, WE CONSIDER METHODS FOR REDUCING THE BURDEN OF GENERATING A CONSTANT AMOUNT OF METADATA AT THE CLIENT SIDE. WHEREAS MANY PRIOR STUDIES ON ENSURING REMOTE DATA INTEGRITY DID NOT CONSIDER THE BURDEN OF GENERATING VERIFICATION METADATA AT THE CLIENT SIDE, THE OBJECTIVE OF THIS STUDY IS TO RESOLVE THIS ISSUE.

«SINCE THE BEGINNING, HUMAN KIND HAS CONSIDERED THE MIND AS THE QUEST TOWARD THE TARGET. ITS HISTORY IS ABOUND WITH REPETITIONS AND REVIEWS ENDING UP A DEAD LOCK OF RELUCTANCE AND INNOVATION OF NEW IDEAS. THE IDEAS ARE NOTHING BUT FRESH BLOOD AND NEW SET OF TARGET«) BAZIAN, 2008, P: 24). »WHEN IT INITIATES, IT TAKES COMMUNICATION AS THE PARAMOUNT TOOL FOR INTERACTION AND BRINGING IN NEW VIEWPOINTS. IN THE EARLY DAYS, BODY GESTURES WERE ENOUGH TO TRANSFER INTERACTION. HOWEVER, AS HISTORY MARCHED ON, THE BODY GESTURES LOST THEIR ROLE FOR LANGUAGE. BY "LANGUAGE"...

THE ONE-POT REACTION OF 1, 3-CYCLOHEXANEDIONE WITH CYANOGEN BROMIDE AND DIFFERENT ALDEHYDES IN THE PRESENCE OF SODIUM AUTOXIDE AND IN METHANOL SOLVENT LEAD TO SELECTIVE PRODUCTION OF XANTHENE DERIVATIVES WITH HIGH EFFICIENCIES. IN THIS RESEARCH, THE FORMATION MECHANISM OF THIS DERIVATIVES IS DESCRIBED AND THE STRUCTURE OF ALL DERIVATIVES OBTAINED WITH USING TECHNIQUES IR, H-NMR AND C-NMR IS INVESTIGATED.

THE INESCAPABLE FACT THAT HYDROCARBON RESERVES IN THE WORLD ARE DECREASING, HAS LED TO CONSIDERABLE RESEARCH AND INVESTMENT IN EXPLORATION FOR NEW CONVENTIONAL HYDROCARBON RESERVES, AND DEVELOPMENT OF UNCONVENTIONAL HYDROCARBON RESOURCES SUCH AS OIL SHALE OR TAR SAND. DEVELOPING A PRODUCTION TECHNIQUE THAT WILL RECOVER CLOSE TO ONE HUNDRED PERCENT OF THE OIL IN A PETROLEUM RESERVOIR HAS BEEN THE DREAM OF PETROLEUM ENGINEERS AND PRODUCTION MANAGERS FOR YEARS. IN SITU COMBUSTION INVOLVES INITIATION OF PROPAGATION OF FIREFRONT OR COMBUSTION ZONE IN THE RESERVOIR, BY AIR INJECTION. IN THIS ARTICLE INVESTIGATED EXPERIMENTAL AND NUMERICAL SIMULATION STUDIES OF THE WET COMBUSTION RECOVERY PROCESS.

A ROBUST MAGNETIC NANOCATALYST WAS PREPARED BY THE IMMOBILIZATION OF TICL4 ON THE SURFACE OF FE3O4@SIO2 NANOPARTICLES AND CHARACTERIZED USING ENERGY DISPERSIVE X-RAY ANALYSIS, SCANNING ELECTRON MICROSCOPY, TRANSMISSION ELECTRON MICROSCOPY, VIBRATING SAMPLE MAGNETOMETER, AND FOURIER TRANSFORM-INFRARED SPECTROSCOPY. THE CATALYTIC ACTIVITY OF THIS NANOCOMPOSITE WAS INVESTIGATED VIA THE SYNTHESIS OF PERHYDROTRIAZOLOTRIAZOLES USING A CONDENSATION REACTION OF AZINE DERIVATIVES AS 1, 3-HETERODIENES WITH POTASSIUM THIOCYANATE IN [3+2] CYCLOADDITION AT AMBIENT TEMPERATURE. THIS CATALYTIC SYSTEM OFFERS SEVERAL ADVANTAGES SUCH AS SIMPLICITY, SHORT REACTION TIMES, EXCELLENT YIELDS AND RECYCLABLE CATALYST.

WE PROPOSE A NOVEL APPROACH TO DESIGN A COLORING WAKEUP SCHEDULE (CWS) FOR THE RADIO OF THE NODES IN WIRELESS SENSOR NETWORKS, IN ORDER TO REDUCE THE END-TO-END LATENCY WITH ENERGY EFFICIENT DATA TRANSMISSION. IN THIS LETTER, A NOVEL COLORING WAKE-UP SCHEDULE (CWS) IS PRESENTED FOR THE RADIO OF THE NODES IN THE WIRELESS SENSOR NETWORKS. THE AIM OF THIS APPROACH IS REDUCING THE END-TO-END LATENCY AND ENERGY CONSUMPTION IN THE DATA TRANSMISSION. IN THE CWS, A PARTICULAR COLOR IS ASSIGNED TO EACH CELL OF THE NODES. BY THIS, THE PACKET OF THE NODE CAN TRANSFER ALONG THE SHORTEST PATH TO THE SINK NODE; THE NODES FIND THEIR NEIGHBOUR ACCORDING TO THEIR TRANSMISSION RANGE AND CHOOSE THE NEIGHBOUR THAT IS NEAR THAN ANY NODES TO THE SINK NODE. THEREFORE THE MENTIONED-SCHEDULE DECREASES THE USELESS ACTIVITIES OF THE NODES WHICH CAUSED TO SAVE THE ENERGY. ALSO, A SPECIFIC GRID IS DEFINED FOR THE SITUATION OF THE CWS NODES TO IMPROVE THE ROUTING. THE VARIOUS SIMULATIONS PROVE THE USEFULNESS OF THE PROPOSED CWS COMPARED TO THE OTHER SCHEDULES IN WIRELESS SENSOR NETWORKS.

MANAGEMENT THEORISTS HAVE CONSIDERED CUSTOMER SATISFACTION AS THE MOST IMPORTANT DUTIES & PRIORITIES FOR FIRM MANAGEMENT & HAVE CONSIDERED NECESSITY OF TOP MANAGERS’ STABLE COMMITMENT FOR ATTRACTING CUSTOMER SATISFACTION AS MAIN PREREQUISITES OF SUCCESS. SO, THIS RESEARCH TRIES TO INVESTIGATE CUSTOMER RELATIONSHIP MANAGEMENT EFFECT ON SATISFACTION OF GEELY’S CUSTOMERS. THIS IS AN APPLIED RESEARCH IN TERMS OF AIM & DESCRIPTIVE-SURVEY RESEARCH IN TERMS OF NATURE & METHOD. IT POPULATION INCLUDES CUSTOMERS OF GEELY CAR AGENCY KERMAN WHO HAVE BOUGHT ONE OF THIS FIRM’S PRODUCES IN THE FIRST SIX MONTHS OF 2015. SAMPLE SIZE HAS BEEN CHOSEN THROUGH SIMPLE RANDOM METHOD & QUESTIONNAIRES HAVE BEEN FILLED OUT BY 384 OF CHOSEN CUSTOMERS. DATA GATHERING TOOLS HAVE BEEN TWO QUESTIONNAIRES; CUSTOMER RELATIONSHIP MANAGEMENT QUESTIONNAIRE & CUSTOMER SATISFACTION QUESTIONNAIRE. THEIR RELIABILITY HAS BEEN 0.935 & 0.88, RESPECTIVELY. TO ANALYZE DATA DESCRIPTIVE & INFERENTIAL STATISTIC (INDEPENDENT T TEST, PEARSON CORRELATION TEST & MULTI-REGRESSION ANALYSIS) HAVE BEEN USED. THEN, NEEDED RESULTING HAS BEEN DONE AFTER DETERMINING EXISTENCE OF CORRELATION BETWEEN DEPENDENT & INDEPENDENT VARIABLES. RESULTS HAVE SHOWN THAT CRM HAS DIRECT & SIGNIFICANT EFFECT ON SATISFACTION OF GEELY CAR AGENCY CUSTOMERS. MOREOVER, ALL COMPONENTS (SERVICE OFFERING QUALITY, PHYSICAL STRUCTURE, HUMAN RELATION) EXCEPT ADVERTISING & TRAINING HAVE DIRECT & SIGNIFICANT EFFECT ON CUSTOMER SATISFACTION.

IN THIS STUDY, WE EVALUATE THE ABSORPTION AND RELEASE OF PARAQUAT FORM CLINOPTILOLITE WITH CATION EXCHANGE RESIN OF PROPYL CARBOXYLIC ACID (PCA). RECOVERY PARAMETER, LIMIT OF DETECTION (LOD), LIMIT OF QUANTIFICATION (LOQ) AND WITHIN RUN ERROR (WRE) FOR PARAQUAT EXTRACTION FORM BLOOD WITH CLINOPTILOLITE WERE 81.7±3.4, 0.58 MGR/ML, 1.93 MGR/ML AND 7.1% RESPECTIVELY. ALSO THESE PARAMETERS FOR EXTRACTION OF PARAQUAT FROM BLOOD WITH PCA METHOD WERE 83.6±3.2, 0.49 MGR/ML, 1.63 MGR/ML AND 6.3%. THE RESULTS SHOWN THAT CLINOPTILOLITE CAN EFFECTIVELY USE AS AN ABSORBENT MATERIAL WITH A CATION EXCHANGE CAPACITY IN PARAQUAT EXTRACTION FORM BLOOD. CLINOPTILOLITE PORE SIZE WAS 5×7 AO (0.5×0.7NM) AND CATION EXCHANGE CAPACITY IN CLINOPTILOLITE AND PCA ARE 1.4-1.6 MEQ/GR AND 10 MEQ/GR RESPECTIVELY. ACCORDING TO THE CATION EXCHANGE CAPACITY OF CLINOPTILOLITE AND PCA IT IS ANTICIPATED THAT EACH GR OF THESE EXTRACT 1.4-1.6 MEQ/GR (=130-149 MG) AND 10 MEQ/GR (=931 MG) PARAQUAT RESPECTIVELY. CLINOPTILOLITE BET WAS MEASURED WITH NANO SORD DEVICE AND PARTICLE SIZE WERE MEASURED WITH PARTICLE SIZE ANALYZER (MASTER SIZER). POTENCIAL ZETA WAS MEASURED WITH ZETASIZER IN -27.9MV. SCANNING ELECTRON MICROSCOPE (SEM) FOR CLINOPTILOLITE WERE DONE BY FIELD-EMISSION SCANNING ELECTRON MICROSCOPE. PARTICLE SIZE ANALYZER RESULTS SUPPORT THE 11-40MM FOR POWDER.

CONCENTRICALLY BRACED FRAME IS KNOWN AS AN ECONOMIC AND COMMON STRUCTURAL SYSTEM BY CIVIL ENGINEERS. ON THE OTHER HAND ITS SEISMIC BEHAVIOR HAS SOME FAULTS. EARLY BUCKLING OF COMPRESSIVE BRACE, UNBALANCED FORCE DISTRIBUTION BETWEEN BRACES AFTER BUCKLING, RESIDUAL ELONGATION OF TENSION BRACE, BOARDING REDUCTION AND IMPACT IN GUSSET PLATE DURING NEXT CYCLES AND LOW ENERGY LOSS ARE SOME IMPORTANT FAULTS OF THIS STRUCTURAL SYSTEM. IN THIS PAPER A NEW CROSS SHAPE MEMBER INCLUDING CYLINDERS, SPRING, PISTONS AND SLIP POSSIBILITY WHICH ITS INTERIOR SPACE IS FULL WITH A COMPRESSIVE LIQUID AND PLACED AT THE CENTER OF BRACES INTERSECTION IS INTRODUCED. MODELING OF THE FRAMES INCLUDING NEW MEMBER HAVE BEEN DONE WITH ANSYS FEM SOFTWARE AND THE EFFECTS OF NEW MEMBER ON FORCE DISTRIBUTION AND BUCKLING POTENTIAL OF BRACES HAS BEEN STUDIED AND ALSO THE HYSTERESIS CURVES OF THE FRAMES UNDER CYCLIC LOAD HAVE BEEN COMPARED WITH CONCENTRICALLY BRACED FRAMES. THE RESULTS SHOW THAT THE DISTRIBUTION OF FORCE IN BRACES OF FRAMES WITH NEW MEMBER IS BALANCED AND THE MAXIMUM AXIAL LOAD AND THE BUCKLING POTENTIAL OF BRACES EXPERIENCE A HIGH REDUCTION. THE REDUCTION OF AXIAL LOAD CAUSES LOWER DESIGN EXPENSES. THE COMPARISON OF THE AREA OF HYSTERESIS CURVE LOOPS SHOWS THAT IN FRAMES WITH NEW MEMBERS THE AREAS HAVE INCREASED AND IT MEANS THE DUCTILITY OF THESE FRAMES AND THEIR SEISMIC BEHAVIOR HAVE PROMOTED.

THE EFFECT OF ADDITIVES ON THE FLUORESCENCE SPECTRA OF SEMICONDUCTOR NANOPARTICLES WAS STUDIED USING ZNSE PARTICLES OF VARIOUS SIZES AND COMPOSITION. BASED ON THE FLUORESCENCE QUENCHING OF QUANTUM DOTS CAUSED BY MATERIAL A SIMPLE, SENSITIVE AND RAPID METHOD WAS DEVELOPED. IN THE END SATISFACTORY RESULTS WERE OBTAINED. THE DIFFERENT SYNTHESIS METHODS WAS ALSO DISCUSSED.

IN THIS STUDY, TIB2-CO COMPOSITE COATINGS WERE THERMALLY SPRAYED ON THE SURFACE OF 304 STAINLESS STEEL SUBSTRATE BY ATMOSPHERIC PLASMA SPRAY. STRUCTURAL EVOLUTION OF POWDER PARTICLES AND THE PLASMA SPRAYED COATINGS WAS INVESTIGATED BY X-RAY DIFFRACTOMETRY (XRD). THE MORPHOLOGY OF POWDER PARTICLES AND MICROSTRUCTURE OF THE COATINGS WERE STUDIED BY SCANNING ELECTRON MICROSCOPY (SEM). AVERAGE PARTICLE SIZE AND FLOW ABILITY OF FEEDSTOCK WERE MEASURED. BOTH COATINGS POSSESS TYPICAL LAMELLAR AND DENSE STRUCTURE AND ALSO HIGH QUALITY CONTACT WITH THE SUBSTRATE. OXIDATION BEHAVIOR OF THE COATINGS WAS STUDIED AT 900OC IN ATMOSPHERIC ENVIRONMENT. THE COMPOSITION AND MORPHOLOGY OF THE OXIDIZED SURFACE WERE ANALYZED. INVESTIGATION SHOWS THE OXIDATION LAYER PERFORMED IN A PARABOLIC OXIDATION RATE. THE KINETICS CURVES OF ISOTHERMAL OXIDATION OF THE COATINGS ILLUSTRATES A SHORT TRANSIENT STAGE FROM RAPID TO SLOW DURING EARLY HOURS OF OXIDATION EXPERIMENT. MOREOVER, THE OXIDATION RATES OF THE COATINGS ARE SIGNIFICANTLY SMALLER THAN SUBSTRATE.

INJECTION WATER AS ONE OF THE KNOWN METHODS HAS MANY APPLICATIONS IN THE OIL INDUSTRY EITHER AS PRESSURE KEEPER OR AS ENHANCED OIL RECOVERY METHOD. ONE OF THE MAIN PROBLEMS IN WATER INJECTION PROCESSES IS INCOMPATIBILITY PROBLEM OF INJECTION WATER WITH FORMATION WATER. IT CAUSES DEPOSITIONS THAT HAVE GREAT EFFECTS ON THE WATER INJECTION PROCESS. SO, PREDICTING LIKELY DEPOSITIONS IS VERY IMPORTANT AND HAS MANY ECONOMIC BENEFITS. IN THIS STUDY, COMPATIBLY BETWEEN FORMATION WATER OF ONE OF THE IRANIAN OIL FIELDS AND INJECTION WATER WHICH IS A CANDIDATE FOR MAINTAINING PRESSURE IN THE RESERVOIR WERE EXAMINED BY COMMERCIAL SOFTWARE OLI. SO, PROBLEMS DUE TO SCALE FORMATION WERE PREDICTED BEFORE PERFORMING THE WATER INJECTION OPERATIONS. IN THIS SOFTWARE, VARIOUS PHYSICAL CONDITIONS THAT WATERS ARE FACING WITH THEM AND DIFFERENT RATIOS OF INJECTION TO FORMATION WATER WERE EXAMINED. RESULTS SHOWED THAT THERE WAS THE POSSIBILITY OF PRECIPITATION OF STRONTIUM SULFATE AND CALCIUM CARBONATE IN RESERVOIR CONDITIONS AND STRONTIUM SULFATE, CALCIUM CARBONATE, AND BARIUM SULFATE IN ATMOSPHERIC CONDITIONS. ALSO, THERE WAS SOME IRON SULFIDE DEPOSIT THAT IT WAS NEGLIGIBLE. SO, CORROSION IS NOT IMPORTANT IN THE CANDIDATE WATER INJECTION PROCESS. SINCE THE AMOUNT AND VARIETY OF COMPOSED SEDIMENTS WERE LITTLE, THE CANDIDATE WATER IS GOOD FOR WATER INJECTION OPERATION INTO THE EXAMINED OIL RESERVOIR.

TODAY AGRICULTURAL CLIMATOLOGY HAS BECOME ONE OF THE MOST IMPORTANT CLIMATOLOGICAL STUDIES IN WHICH WE MEASURE THE POTENTIALS OF A SPECIFIC PLANT FOR ADAPTATION IN A SPECIFIC REGION.THIS STUDY TRIED TO UNDERSTAND THE DIFFERENT ECOLOGICAL ABILITIES OF SUGARBEET CULTIVATION AND ALSO TO FIND OUT THE RELATIONS BETWEEN SUGARBEET YIELD WITH OPTIMUM AND RESTRICTIVE TEMPERATURES IN DIFFERENT PHENOLOGY STAGES IN EASTERN PART OF IRAN IN KHORASAN PROVINCE. PARAMETERS SUCH AS TEMPERATURE, FREEZING DAYS, SUMMERS TEMPERATURE MEAN, TEMPERATURE MEAN IN LATE OF GROWING SEASON AND OPTIMAL AND CRITICAL TEMPERATURES WAS MEASURED.IN ORDER TO CLASSIFY THE REGION, DE MARTONNE EXPANDED CLASSIFICATION WAS PERFORMED.PLANTATION DATE WAS DETERMIND AS THE TEMPERATURE FLUCTUATION WAS ABOVE THE BASE TEMPERATURE AND THE MINIMUM OF TEMPERATURE WAS ABOVE 12 DEGREE FOR TWO WEEKS STRAIGHT.TIMETABLE FOR PHONOLOGY STAGES ACCORDING TO REQUIRED GDD OF EACH STAGE WAS ESTIMATED. CLIMATOLOGICAL REQUIREMENTS AND APPROPRIATE AND RESTRICTIVE TEMPERATURES FOR DIFFERENT PHONOLOGY STAGES IN SUGARBEET WERE CALCULATED AND PROBABILITY IN OTHER PARTS OF THE PROVINCE WAS CALCULATED. FINALLY AFTER DRAWING THE CO-PARAMETER MAPS WITH ARCGIS VERSION 9.3 AND COMBINING THEM INTO ONE FINAL MAP, THE SUGARBEET CULTIVATION ZONES IN KHORASAN PROVINCE WAS DEVIDED INTO 4 AREA WHICH ARE CATEGORIZED AS BELLOW: 1-VERY DESIRABLE INCLUDING MASHHAD, CHENARAN, GHUCHAN, FARIMAN, NEYSHABUR AND EASTERN SIDES OF SABZEVAR.2-DESIRABLE REGIONS INCLUDING DAREGAZ, KALAT, SARAKHS, TORBAT E JAAM, TORBAT E HEYDARIYEH, TORBAT E JAM, KHAAF, ROSHTKHAR, KASHMAR, SABZEVAR, JOVEIN AND JOGHATAI.3- SEMI-DESIRABLE REGIONS INCLUDING GONABAD, KHALILABAD, MAHVELAT, BARDASKAN AND BAJESTAN.4 - UNDESIRABLE REGIONS INCLUDING WESTERN PART OF BADJESTAN AND SOUTH EAST OF KHAAF.

SYNTHESIS OF COPOLYMERS SUCH AS POLY (STYRENE ALTERNATIVE MALEIC ANHYDRIDE) (SMA), (SMA+MELAMINE+1, 3-DIAMINOPROPANE) (CSMA-M), (CSMA-M+PROPANEDIOIC ACID) (CSMA-MP) AND (CSMA-M+BUTANEDIOIC ACID) (CSMA-MB) FOR REMOVING HEAVY METAL IONS FROM AQUEOUS SOLUTIONS. ADSORPTION OF CD (II), PB (II) AND ZN (II) ON MODIFIED COPOLYMERS AND ADSORPTION BEHAVIOR OF THESE HEAVY METAL IONS ON THE ADSORBENTS WERE STUDIED BY ALTERING THE CHARACTERS SUCH AS PH, ADSORBENT DOSE, CONTACT TIME, AND HEAVY METAL IONS CONCENTRATION. ADSORPTION PERCENTAGE WAS INCREASED BY INCREASING EACH OF THESE PARAMETERS. THE ISOTHERM MODELS SUCH AS: LANGMUIR, FREUNDLICH, TEMKIN, AND DUBININ–RADUSHKEVICH WERE APPLIED TO ILLUSTRATE ADSORPTION EQUILIBRIUM. THE OUTCOMES SHOWN THAT THE BEST CONSISTENCY WAS ACCESSED WITH THE LANGMUIR ISOTHERM EQUATION, PRODUCTION MAXIMUM ADSORPTION CAPACITIES OF THESE ADSORBENTS ARE VERY SUITABLE FOR REMOVING HEAVY METAL IONS FROM AQUEOUS SOLUTIONS. THE ADSORBENTS WERE CHARACTERIZED BY FOURIER TRANSFORM INFRARED SPECTROSCOPY SCANNING ELECTRON MICROSCOPY AND X-RAY DIFFRACTION ANALYSIS.

IN THIS PAPER, WE PROPOSE A CUSUM CONTROL CHART TO MONITOR THE WEIBULL SCALE PARAMETER OF TYPE II CENSORED RELIABILITY DATA IN TWO-STAGE PROCESSES. A CUMULATIVE SUM (CUSUM) CONTROL CHART IS DEVISED TO DETECT DECREASES IN THE MEAN LEVEL OF RELIABILITY-RELATED QUALITY CHARACTERISTIC. THE PROPOSED CONTROL SCHEME IS BASED ON STANDARD SMALLEST EXTREME VALUE (SSEV) DISTRIBUTIONS DERIVED FROM WEIBULL PROCESSES TO EFFECTIVELY ACCOUNT FOR THE CASCADE PROPERTY WHICH IS THE MAIN CHARACTERISTIC OF MULTISTAGE PROCESSES. SUBSEQUENTLY, SIMULATION STUDY IS CONDUCTED TO EVALUATE THE PERFORMANCE OF THE CONTROL CHARTS USING AVERAGE RUN LENGTH (ARL) CRITERION. MOREOVER SENSITIVITY ANALYSIS IS DONE TO STUDY THE IMPACT OF FAILURE NUMBER IN THE SAMPLE SIZE ON THE PERFORMANCE OF PROPOSED CONTROL CHART.

THIS STUDY PROPOSES A SINGLE MATHEMATICAL MODEL IN A GREEN SUPPLY CHAIN NETWORK CONSISTING OF SUPPLIERS, MANUFACTURERS AND DISTRIBUTION CENTERS FOR PHARMACEUTICAL PRODUCTS. THE MAIN OBJECTIVES ARE: MINIMIZING OPERATIONAL COST CONSIDERING TOTAL PURCHASING COST OF MATERIALS, PRODUCTION COSTS (INCLUDING COST OF POOR QUALITY), TRANSPORTATION COST OF MATERIALS, AND SOCIAL COST OF CARBON DIOXIDE EMISSIONS. WE SOLVED THE PROPOSED MATHEMATICAL MODEL BY THE LINGO 16.0 SOFTWARE.THE RESULTS ILLUSTRATE BY INCREASING THE SOCIAL COST RATE OF CARBON DIOXIDE EMISSIONS, THE AMOUNT OF THE EMISSION OF CARBON DIOXIDE WILL DECREASE.
