پروتکل جلسات ذهن آگاهی
ذهن آگاهی به معنی توجه کردن به هدف در حال حاضر است آن‌هم باکیفیتی مانند همدردی، کنجکاوی و پذیرش.
برای آموزش ذهن آگاهی در پژوهش حاضر از پروتکل تلفیقی مبتنی بر دو جریان عمده ذهن آکاهی یعنی کاهش استرس مبتنی بر ذهن آگاهی و شناخت درمانی مبتنی بر ذهن آگاهی استفاده شده است. این پروتکل در پژوهشی توسط ون سون و همکاران (۲۰۱۱) مورد استفاده قرار گرفت و معتبر گزارش شد. در پژوهشی که در ایران توسط قاسمی جوبنه (۱۳۹۴)انجام شد،…
Flexural behaviour of steel fibre-reinforced concrete under cyclic loading
Flexural behaviour of steel fibre-reinforced concrete under cyclic loadingThis paper presents the results of cyclic loading tests on fibre-reinforced concrete (FRC). The main objectiveof this research is to evaluate simultaneously the influence of the workability, the steel fibres and the compressivestrength on the flexural behaviour of FRC under cyclic loading. Prismatic concrete specimens havingdimensions of 150*150* 700 mm were fabricated with concrete of various workability and differentcompressive strengths (30, 60 and 80 MPa) and reinforced with hooked end steel fibres of aspects ratios of65 and 80 at contents of 0.5 and 1%. A four-point bending test with notched specimens was conducted usingDigital Image Correlation technique. The orientation of the fibres, failure modes,…
بررسی فقهی و حقوقی حق فسخ به استناد خیار تخلف از شـرط فعل …
چکیدهحق فسخ یکی از استثناهای وارده بر اصل لزوم قراردادهاست و در حقوق ایران فسخ قرارداد به صورت پراکنده در قانون بیان شده است، حق فسخ جنبه قهقرایی ندارد و از زمان فسخ طرفین نسبت به تعهدات آینده بری میشوند، فسخ یک نوع فعل اعتباری است که به صورت یک طرفه و با یک اراده واقع شده و نیاز به قصد انشاء داشته و از نظر ماهیتی نوعی ایقاع است که با یک اراده انجام گرفته و اثر عقد معین یا ایقاع معین را از بین برده و به حالت زمان حدوث عقد بر میگرداند، به…
Influence of fibre distribution and orientation on the flexural behaviour of beams cast from flowable hybrid polymer–steel FRC
Influence of fibre distribution and orientation on the flexural behaviour of beams cast from flowable hybrid polymer–steel FRCabsttrract
The present study analyses the performance of full-scale beams cast from flowable hybrid polymer FRCwith regard to fibre distribution and orientation. To identify possible flow-induced effects, variations ofthe fibre contents and orientation factors were investigated along the length and over the height of thebeams. The study includes a comparison of the fibre distribution and orientation between standard specimensand full-scale beams, and the influence thereof on flexural behaviour and design assumptions. Forthe full-scale beams, it is found that fibres, even combined, distribute differently by type: steel fibres tendto segregate…
stress-strain curves for fibre-reinforce concrete
stress-strain curves for fibre-reinforce concreteABSTRACT The paper examines the effects of the addition ofvarious fibres, including fibrillated polypropylene as well asround straight, Duoform, crimped and hooked steel, on thecompressive stress-strain properties of a basic concrete matrix. The ultimate compressive strengths of cube, equivalentcube and prism specimens, with MGA pads to reduce platenfriction, are shown to be only slightly affected whereas thefracture toughness of the fibre reinforced specimens isincreased considerably for all fibres. …
Stress-strain model for concrete under cyclic loading
Stress-strain model for concrete under cyclic loadingA hysteretic stress–strain model is developed for unconfined concrete with the intention of providing efficientmodelling for the structural behaviour of concrete in seismic regions. The proposed model is based on thefindings of previous experimental and analytical studies. The model for concrete subjected to monotonic andcyclic loading comprises four components in compression and tension – an envelope curve (for monotonic andcyclic loading), an unloading curve, a reloading curve and a transition curve. Formulations for partial unloadingand partial reloading curves are also presented. The reliability of the proposed constitutive model is investigatedfor a reinforced concrete member using a non-linear finite-element…
Seismic Behavior of Concrete Columns Confined with Steel and Fiber-Reinforced Polymers
Seismic Behavior of Concrete Columns Confined with Steel and Fiber-Reinforced PolymersResults from an experimental program are presented in which 12356 mm diameter and 1473 mm long columns were tested underconstant axial load and reversed cyclic lateral load that simulatedforces from an earthquake. Each specimen consisted of a columncast integrally with a 510 x 760 x 810 mm stub that represented abeam-column joint area or a footing. The test specimens weredivided into three groups. The first group consisted of four columnsthat were conventionally reinforced with longitudinal and spiralsteel reinforcement. The second group contained six reinforcedconcrete columns that were strengthened with carbon fiber-reinforcedpolymers (CFRP) or glass fiber-reinforced polymers(GFRP)before testing. The…
تعریف کلی علم روانشناسی
روانشناسی یعنی : مطالعه رفتار یا مطالعه علمی رفتار موجود زنده ، مطالعه علمی رفتار و فرایند های روانی ، علمی که رفتار و زیرساختهای آن، یعنی فرایندهای فیزیولوژیکی و شناختی را مطالعه می کند و در عین حال حرفه ای است که در آن از دانش حاصل برای حل عملی مسائل انسانی ، استفاده میشود .
هر چند سابقه علمی روانشناسی بسیار کوتاه است ، اما در همین دوران کوتاه نیز رویدادهای بسیار و در عین حال مهم باعث گردیده است روانشناسی تا بدین حد در ابعاد مختلف…
