Serious floor heave in gob-side entry retaining (GER) with fully-mechanized gangue backfilling mining affects the transportation and ventilation safety of the mine. A theoretical mechanical model for the floor of gob-backfilled GER was established. The effects of the mechanical properties of floor strata, the granular compaction of backfilling area (BFA), the vertical support of roadside suppor...

Aims of course/workshop This workshop will review the definition, etiology and pathophysiology of non-relaxing pelvic floor muscle tone, as well as discuss sexual function and past sexual experience in relation to the pelvic floor. Specific pelvic floor dysfunctions associated with pelvic floor over-activity will be reviewed. Special attention will be devoted to female genital pain, bladder pai...

To place an order under this method, the customer calls a broker, who time-stamps the order and prepares an office order ticket. The broker then sends the order to a booth on the exchange floor. There, a floor order ticket is prepared, and a clerk hand delivers the order to the floor trader for execution. In some cases, the floor clerk may use hand signals to convey the order to floor traders. ...

OBJECTIVE The purpose of this article is to review the relevant anatomy and sonographic, fluoroscopic, and MRI options for evaluating patients with pelvic floor disorders. CONCLUSION Disorders of the pelvic floor are a heterogeneous and complex group of problems. Imaging can help elucidate the presence and extent of pelvic floor abnormalities. MRI is particularly well suited for global pelvic...

We measured forest floor C02 flux in three age classes of forest in the southern Appalachians: 20-year-old, 85-year-old, and old-growth. Our objectives were to quantify differences in forest floor C02 flux among age classes, and determine the relative importance of abiotic and biotic driving variables. Forest floor C02 flux was measured using an openflow infrared gas analyzer measurement system...

Purpose: Pelvic floor muscle dysfunction is a common cause of constipation. This dysfunction does not respond to current treatments of constipation. Thus, it is important to identify this type of dysfunction and the role of these muscles in constipation. The purpose of the present study was to review the previously published studies concerning the role of pelvic floor muscles dysfunction ...

INTRODUCTION The human pelvic floor is a complex structure and pelvic floor dysfunction is seen frequently in females. MATERIALS AND METHODS This review focuses on the surgical reconstruction of the pelvic floor employing recent findings on functional anatomy. A selective literature research was performed by the authors. RESULTS Pelvic floor activity is regulated by 3 main muscular forces t...
