ConclusionThis experimental and analytical investigation on the nanostructured YSZ coated Inconel 718 substrate leads to the following important conclusions. Successful coating deposition of as-synthesized nano-YSZ powder (by sol gel route) by plasma spraying route is possible on Inconel 718 substrates. Retention of nanostructure is achieved by monitoring molten state of nanoagglomerates (temperature and velocity) by CCD camera and carefully optimizing process parameters. From the Taguchi design method, particle velocity is found to be the most significant factor followed by SOD and particle temperature, influencing the adhesion strength of coated sample.

Maximum adhesion of 40.56MPa is achieved experimentally by optimizing process parameters using Taguchi experimental design.
Globally, approximately 287,000 women died from causes related to pregnancy and childbirth in 2010. Of these, 162,000 were in Sub-Saharan Africa and 83,000 were in South Asia. The maternal mortality ratio (MMR defined as the number of women who die during pregnancy and childbirth per 100,000 live births) ranges from 16 in the developed countries to 220 in South Asia and 500 in Sub-Saharan Africa [1]. Lack of access to and utilization of health care services for delivery are among the main reasons for the high maternal and neonatal mortality rates in these regions [2�C5].

Maternal death can occur anytime in pregnancy, but delivery is by far the most dangerous time for both mother and baby [6].The major complications that account for 80 percent of all maternal deaths are severe bleeding and infections after childbirth, high blood pressure during pregnancy and unsafe abortion [7]. Antenatal care, delivery by skilled health professionals, and postnatal care would ensure timely management and treatment of complications to reduce maternal deaths. Despite the importance of institutional delivery in preventing maternal death, about 42 percent of the births in developing countries were delivered outside a health facility, and 35 percent were not attended by trained personnel. Noninstitutional delivery made up more than 80 percent of the births in a few less developed countries such as Ethiopia (95 percent), Afghanistan, Bangladesh, Lao People’s Democratic Republic, and Nepal [8].

Factors that prevent women from receiving or seeking health Batimastat care during pregnancy and childbirth include inadequate services, poverty, distance, lack of information, and cultural practices [7, 8]. Health facilities and services vary widely between the developed and developing countries. In low resource countries, the hospital bed-population and doctor-population ratio was about 0.4 and 0.
