These studies have also shown that corresponding to the angle of incidence i between the liquefied gas and metal, that is to say to the angle which the layer of liquid forms when it meets the stream of metal, is an angle of reflection r&lt;i. As a result, it drops are to be prevented from rebounding and adequate protection provided for the metal, the conditions under which the liquefied gas provides protection for the casting stream must be governed by the diameter d and the height H of the said stream.
Principally, the present invention has as an object the avoidance or minimisation of the drawbacks of known methods of protecting streams of metal so that satisfactory protection may be provided for such streams even when their diameter and height become considerable. The exemplary embodiment relates to a nanofiber-reinforced composition. It finds particular application in conjunction with the delivery of such a composition to a wound site within the body, and will be described with particular reference thereto. However, it is to be appreciated that the present exemplary embodiment is also amenable to other like applications.
Surgical procedures have been developed for performing pelvic surgery and other internal surgical operations with an operating laparoscope. The laparoscope is inserted into a trocar tube extending through an incision in the body into the pelvic area. The laparoscope typically includes an optical passage for viewing the surgical area and another passage for receiving the instruments that are used in performing surgery on the tissue inside the body. The laparoscope permits surgeries to be performed deep within the body without requiring a large incision and thus facilitates a more rapid healing.
At the surgical site, bands of fibrous scar tissue can cause adhesions to form. These adhesions can result in two normally separate organs being bound together. Thus, organs which would normally slide over each other tend to pull on each other, resisting healing. Adhesions can also cause pain by pulling on nerves. To reduce the formation of adhesions, techniques have been developed for applying an adhesion barrier to the surgical site. The adhesion barrier may be formed of fine fabric biodegradable material which separates the organ on which the operation was performed from neighboring tissue. One problem in applying such a barrier is that it is difficult to insert the fabric material through a small diameter tube. Thus, in some procedures, a trocar with

These report have also shown that corresponding to the angle of incidence i between the liquefied gas and metallic element, that is to say to the angle which the layer of fluid forms when it meets the stream of metallic element, is an angle of reflection r&lt;i. As a result, it drops are to be prevented from bounce and adequate protection provided for the metal, the conditions under which the liquefied gas provides protection for the casting stream must be governed by the diameter d and the height H of the said stream.

 Surgical routine have been developed for performing pelvic surgery and early internal surgical operation with an operating laparoscope. The laparoscope is inserted into a trocar tube gallop through an incision in the consistency into the pelvic area.

The laparoscope permit surgeries to be perform deep within the body without requiring a large incision and thus facilitate a more rapid healing. 
 At the surgical site, bands of hempen scar tissue can cause adhesions to form. These adhesions can result in two normally separate organs being tie down together. Thus, organs which would normally slide over each other tend to pull on each early, resisting healing. Adhesions can besides induce pain by pulling on heart. To reduce the formation of adhesion, techniques have been developed for applying an attachment barrier to the surgical site. The adhesion barrier may be formed of fine fabric biodegradable fabric which separates the organ on which the operation was performed from neighboring tissue. One problem in applying such a barrier is that it is difficult to tuck the fabric material through a small diameter tube. Thus, in some procedures, a trocar with
