There are numerous oil fields that approaching the end of their lifetime and have great geothermal potential considering temperature water cut. On other hand, industry is facing challenges due to increasingly stringent environmental regulations. An example this case France where extraction will be forbidden starting from year 2035. Therefore, some companies switching business investing in proje...

teratomas are rare germline tumors that originate from one or more embryonic germ cell layers. teratoma of the kidney is extremely rare, and less than 30 cases of primary intrarenal teratomas have been published to date. we report the main radiologic features of an unusual case of mature cystic teratoma arising from the left kidney in a two-year-old boy. a left-sided abdominal mass was detected...

this experiment was conducted in order to optimize the use of paddy fields as second cropping in the mazandaran province. study planed with 8 new cultivars and carried out in randomized complete block design with four replications during two years 2006 and 2007 in dashte-naz agricultural research station of sari. nursery prepared in the september and seedlings were transferred to the field in t...

We have developed a hybrid model of the solar dynamo on the lines of the Babcock–Leighton idea that the poloidal field is generated at the surface of the Sun from the decay of active regions. In this model magnetic buoyancy is handled with a realistic recipe wherein toroidal flux is made to erupt from the overshoot layer wherever it exceeds a specified critical field (10 G). The erupted toroida...

The background for our research is oil and gas production at marginal (i.e. small in total oil and gas volume) fields in the Danish sector of the North Sea, as described in our work [1]. The DONG Energy E&P operated production platform Siri is used as demonstration case. From a production perspective marginal fields are very challenging since they mature more rapidly, i.e. in the range of month...

The sparse coding hypothesis has enjoyed much success in predicting response properties of simple cells in primary visual cortex (V1) based solely on the statistics of natural scenes. In typical sparse coding models, model neuron activities and receptive fields are optimized to accurately represent input stimuli using the least amount of neural activity. As these networks develop to represent a...
