Calibrating and monitoring the western gray whale mitigation zone and estimating acoustic transmission during a 3D seismic survey, Sakhalin Island, Russia

A 3D marine seismic survey of the Odoptu license area off northeastern Sakhalin Island, Russia, was conducted by DalMorNefteGeofizika (DMNG) on behalf of Exxon Neftegas Limited and the Sakhalin-1 consortium during mid-August through early September 2001. The key environmental issue identified in an environmental impact assessment was protection of the critically endangered western gray whale (Eschrichtius robustus), which spends the summer–fall open water period feeding off northeast Sakhalin Island in close proximity to the seismic survey area. Seismic mitigation and monitoring guidelines and recommendations were developed and implemented to reduce impacts on the feeding activity of western gray whales. Results of the acoustic monitoring program indicated that the noise monitoring and mitigation program was successful in reducing exposure of feeding western gray whales to seismic noise

OPTIMIZATION OF PHARMACOTHERAPY OF PATIENTS WITH CHRONIC HEART FAILURE FUNCTIONAL CLASS II ON INFLUENCE ON THE REGULATORY AND ADAPTIVE STATUS

The study involved 100 people (50 men and 50 women) aged 32 to 68 years. The first group consisted of 53 patients with chronic heart failure class II and III stage of hypertensive disease (29 men and 24 women, age 52,9±10,7 y. o.), treated with sustained-release metoprolol succinate (betaloc ZOK of «AstraZeneca», Sweden production, of 97,3±9,5 mg/day doze). The second group included 47 patients with chronic heart failure class II and III stage of hypertensive disease (21 men and 26 women, age 57,5±5,7 y. o.), receiving quinapril (accupro of «Pfizer», USA production in 24,7±13,4 mg daily doze. Treadmill activity with measuring of the maximum oxygen consumption on effort, 24-hour blood pressure monitoring, echocardiography and NT-proBNP testing, сardio-respiratory synchronism trial was carried out initially and after six months of therapy. Beta-blocker and angiotensine converting enzyme inhibitor are equally reducing blood pressure, are not identical in influencing the in statedly-adaptive status patients and the latter can be preferred
