The sore expands into deeper layers of the skin . Rather than work its way into deeper layers of the skin , this fungus thrives in the nails and spreads through shared toenail clippers or other pedicure tools . The geological history that may have contributed to the extraordinary levels of marine invertebrates in the shallow waters of the north coast of PNG may extend into deeper waters of the region . One method involves opening the cranium to place electrodes on the surface of the brain or to insert electrodes into deeper portions of the brain which enables measuring epileptic discharges during seizures . As juvenile red drum attain sizes > 200 mm SL , they migrate into deeper portions of the river or immigrate into other habitats in Tampa Bay ( Peters and McMichael , 1987 ) . Hot spot volcanoes , in particular , often sit atop long , narrow plumes that can reach into deeper regions of the mantle and billions of years back in time . If the site begins to dry up , move enclosures into deeper areas of the pool to prevent egg or tadpole death . " As industry moves into deeper areas of the Gulf of Mexico , we need this body of knowledge to evaluate effectively operating plans and permits for deep water facilities . History : Patients with ulcerative colitis ( UC ) most commonly present with bloody diarrhea , whereas patients with Crohn disease ( CD ) usually present with nonbloody diarrhea.Abdominal pain and cramping , fever , and weight loss occur in more severe cases.The greater the extent of colon involvement , the more likely the patient is to have diarrhea.Rectal urgency or tenesmus reflects reduced compliance of the inflamed rectum.Patients might have formed stools if their disease is confined to the rectum.As the degree of inflammation increases , systemic symptoms develop , including low-grade fever , malaise , nausea , vomiting , sweats , and arthralgias.Fever , dehydration , and abdominal tenderness develop in severe UC , reflecting progressive inflammation into deeper layers of the colon.The presentation of CD is generally more insidious than that of UC , with ongoing abdominal pain , anorexia , diarrhea , weight loss , and fatigue.Grossly bloody stools , while typical of UC , are less common in CD.Stools may be formed , but loose stools predominate if the colon or the terminal ileum is involved extensively.One half of patients with CD present with perianal disease ( eg , fistulas , abscesses ) . Agricultural Drainage Wells ( ADWs ) - - also known as shallow injection or dry wells - - have been used in some farming situations as a way to carry excess water from surface or subsurface drainage systems directly into deeper layers of the ground .
