Many types of breakwater have been developed to withstand the emormous wave force of a deep sea area.However, most have not proven viable in terms of constructability, economy and so on. The sloping slit caisson is expected to overcome these problems. It acts to dissipate wave energy by a front perforated wall and a wave chamber.The downward force acting on the slope increases the caisson's stability.This study describes the efficiency, design and construction method, and then explains the results of actual construction.
Introduction:The condition observed in coagulation activity during pregnancy was described as a "hypercoagulable state" (Alexander, 1955). Lately, it'sreported that acute intracascular coagulation often occurred during pregnancy and delivery, particularly in cases of toxemia of pregnancy, intrauterine death, abruptio-placentae and post-partum haemorrhage.The purpose of the present investigation is to research the extensive DIC in vaginal bleeding.Patients and Methods: According to bleeding volume in vaginal deliverys 163 cases were divided into two groups; the first group has lesser bleeding volume than 500ml (132 cases) and the second greater than 500ml (31 cases). Their specimen were drawn seriously in the full term or false labor, the first and second stage, 20 minutes after delivery and 3, 6, 12, 24 and 48 hours post partum, and the following determinations were made Fbg, platelet counts, FDP, eug LA, eug+SK LA (Sta), eug+SK LA (Htd), SFMC, PTT, PT, TT and PRT.Results: eug+SK LA (Std) and eug+SK LA (Htd) decreased from 20 minutes after delivery. SFMC showed arising from the first or second stage to 48 hours after delively. FDP increased from the first stage to 6 hour after delivery and decreased from 12 hours after delivery. Fbg gradually increased from the first stage to 20 minutes after delivery. Eug LA gradually decreased in the first and second stage, but 20 minutes after delivery increased in group I and remained unchanged in group II and gradually increased from 3 hours after delivery. Platelet counts decreased during 3, 6 hours after delivery.Discussion: Serial coagulation and fibrinolysis studies in vaginal delivery showed a pattern DIC such as decreased platelet count and fibrinogen level with
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
