Most modern-time and extinct medieval caravanserais relatively belong to the ancient periods of human civilization. They were Usually chosen in particular spots along major trade routes, some these caravansaries have acquired special significance Mesopotamia that they been considered one most important focal points reference field Geography Trade History studies. These used provide trading cara...

Groundwater is an important source of drinking water in coastal regions with predominantly unconsolidated sediments. To protect and manage extraction wells these regions, reliable estimates groundwater flow velocities around well fields are paramount importance. Such measurements help to identify the dynamics its response stresses, optimize resources management, calibrate models. In this articl...

Aiming at the problem that casing deformation can easily occur in tight oil horizontal well fracturing, based on rock mechanics experiments and probability statistics, distribution characteristics law of near-wellbore stress field reservoir STH M56 were solved analyzed by using finite element modeling numerical method. The research shows (1) max/min ratio is 1.2, difference less than 8 MPa, thi...

An 8-year-old girl was evaluated for fevers of 39.4°C that developed 10 days after returning from a family camping trip. She complained of diffuse headache, nausea, and occasional emesis. Before her illness, 3 transient erythematous papules resembling insect bites on her abdomen were noted. Sore throat, cough, conjunctivitis, diarrhea, arthralgias, and myalgias were absent. Her symptoms, includ...

OBJECTIVE Numerous studies support the use of warmed intravenous fluids in hypothermic patients. The most effective method to accomplish this goal in a cold prehospital, wilderness, or combat setting is unknown. We evaluated various methods of warming intravenous fluids for a bolus infusion in a cold remote environment. METHODS One liter and 500 mL bags of intravenous fluid at 5 degrees C wer...

Although existing deep geothermal wells have confirmed that shallow magmatic intrusions heat circulating hydrothermal fluids to supercritical temperatures, successfully utilizing such for power generation has proven challenging. As an alternative, using drilled into the vicinity of injection rather than production potential enhance extraction from intrusion, while simultaneously providing fluid...

BACKGROUND Little is known about the environmental and public health impact of unconventional natural gas extraction activities, including hydraulic fracturing, that occur near residential areas. OBJECTIVES Our aim was to assess the relationship between household proximity to natural gas wells and reported health symptoms. METHODS We conducted a hypothesis-generating health symptom survey o...

In todays high voltage processes the optimization of process and layout design is a key point to get competitive products. Effects like punch-through between two junctions and breakdown near the surface of the wells make it necessary to analyze complex three-dimensional process steps by simulators which give accurate answers to the process engineers.
