OBJECTIVE To investigate the effect of mindfulness training on pain tolerance, psychological well-being, physiological activity, and the acquisition of mindfulness skills. METHODS Forty-two asymptomatic University students participated in a randomized, single-blind, active control pilot study. Participants in the experimental condition were offered six (1-h) mindfulness sessions; control part...

The influence of fluctuations of atmospheric pressure on the functional state of the humans was studied during spring, autumn and winter seasons. Sensory-motor reaction time and selfreported wellbeing, activity and mood were used for evaluation of functional state. The inter-individual variations of those parameters were compared to meteorological parameters using rank order correlation and gen...

a synthesis of well logs was carried out and drilling mud weight data were analyzed to figure outanomalous high fluid pressure within the triassic evaporitic cap rock (the dashtak formation) andstudy its impact on the geometry of anticlinal traps in the gas rich gavbandi province located in thesoutheast part of the zagros mountains. the results indicated that the location of anticlinal traps at...

the narrow operating window between pore pressure and fracture pressure makes drilling difficult in some operations. a feasibility study of managed pressure drilling (mpd) is carried out on iran darquain oil field. the previous wells drilled in this field showed that mud returns were lost during drilling gadvan formation. the present work addresses this problem by means of surface back pressure...

Pore pressureis defined as the pressure of the fluid inside the pore space of the formation, which is also known as the formation pressure. When the pore pressure is higher than hydrostatic pressure, it is referred to as overpressure. Knowledge of this pressure is essential for cost-effective drilling, safe well planning, and efficient reservoir modeling. The main objective of this study is to ...
