In this article we generalize the concept of the pseudosteady-state productivity index for the case of multiple wells producing from or injecting into a closed rectangular reservoir of constant thickness. The work complements the analytical study by Rodrı́guez and Cinco-Ley for systems produced at constant flowing pressures. Wells are represented by fully penetrating vertical line sources locate...

Penetrating scrotal trauma is an uncommon injury that is often secondary to civilian or combat violence. Much of the literature on the topic is from case reports, small retrospective series from civilian trauma centers, and reports from combat zones. In this manuscript, a case report involving self-inflicted penetrating scrotal trauma from our institution is presented. Following the case report...

introduction: penetrating cardiac injuries generally occur secondary to gunshot or stab wounds and have a high mortality rate. they are rare and often fatal in children. when a foreign object penetrates the myocardium, it is dangerous to remove it, suddenly, and should be removed gradually to prevent excessive bleeding. case report: we report a case of an unusual penetrating cardiac injury in a...

BACKGROUND Deep penetrating nevus is a recently described variant of melanocytic nevi with clinical and histopathological features that may be confused with malignant melanoma, blue nevus, pigmented Spitz nevus, or congenital melanocytic nevus. We report a case with linear arrangement of multiple deep penetrating nevi. To our knowledge, such presentation has never been reported in the literatur...

The support of roadways in soft coal seams is a challenge deep mines. For gas-rich seams, many methods are developed to drain the gas before mining. penetrating hydraulic reaming (PHR) one most efficient reduce content and pressure seams. However, PHR method will cause large holes seam, which brings difficulty in-seam control. strength parameters essential for roadway stability analysis. sampli...

Ground penetrating radar (GPR) is a commonly-used geophysical technique, yet the use of water-penetrating (WPR) has been less-well researched and published on. This surprising, given wide GPR on ice success early aquatic experiments in 1970s 1980s. The past 15 years have seen advances modes antenna deployment, understanding limiting environmental conditions applications to geotechnical engineer...

BACKGROUND AND PURPOSE The relation between serum total cholesterol levels and stroke is controversial. The Akita Pathology Study provides data on the association of serum total cholesterol, different types of stroke, and distribution of stenosis in cerebral arteries. METHODS The data are based on 750 autopsied men aged 30 years and older who were admitted to a local hospital in northeast Jap...

Background: Penetrating abdominal injury occurs when a foreign object pierces the skin. The morbidity and mortality associated with penetrating abdominal trauma is related to the intraabdominal complications. This study is, therefore, intended to determine the abscess rate resulting from penetrating abdominal trauma in Ahmadu Bello University Teaching Hospital Zaria. Method: A 6-year (January 2...
