“…For pregnant women obstructed labor remains an important cause of not only maternal death but also short and long term disability like obstetric stula, uterine rupture, uterine prolaps, nerve damage, incontinence, puerperal sepsis, postpartum haemorrhage, and infertility from hysterectomy [21]. This can be prevented by accessing skilled delivery services such as plotting partograph during the progress of labor [22,23]. Therefore, this systematic review and meta-analysis aimed to estimate the pooled prevalence of partograph use among obstetric care providers and its determinant factors in Ethiopia.…”

Background Globally, a total of 13.6 million women have died due to maternal causes from 1990 to 2015. Majority of these deaths occurred in resource-limited countries. Among the causes of these deaths, obstructed and prolonged labor covers the highest percentage, which could be prevented by cost-effective and affordable health interventions like partograph use. Therefore, this systematic review and meta-analysis aimed to assess the level of partograph utilization among obstetric care providers and its associated factors in Ethiopia. Method for this review, we used the standard PRISMA checklist guideline. Different online databases were used for the review: PubMed/Medline, Google Scholar, EMBASE, Cochrane Library, HINARI, WHO Afro Library Databases, and African Online Journals. Based on the adapted PICO principles, different search terms were applied to achieve and access all the essential articles. Microsoft Excel was used for data entrance and Stata version 11.0 (Stata Corporation, College Station, Texas, USA) for data analysis.Result Nineteen studies were included in this systematic review and meta-analysis with a total of 6237 obstetric care providers. The overall pooled prevalence of partograph utilization was 59.95% (95%CI: 46.8–73.09, I2 =99.4%, P <0.001). Being midwifery profession (adjusted odds ratio (AOR):3.97; 95% confidence interval (CI):95%CI:2.63–5.99, I2 =28.8%, P=0.198), presence of supervision (AOR = 3.21; 95%CI: 2.22–4.66, I2=0.0%, p=0.742), Basic Emergency Obstetric and Newborn Care (BEmONC) training (AOR = 2.90; 95% CI: 2.19–3.84, I2=36.9%, P=0.13), Knowledge of partograph (AOR=2.5; 95%CI: 1.6–3.8, I2=64.58%, P=0.024), on-the-job refresher training on partograph (AOR =5.7; 95%CI:2.5–12.9, I2=87.8%, P<0.001), favorable attitude (AOR=2.12; 95%CI: 1.48–3.04, I2=0.0%, P=0.58), and working at health center (AOR=3.50; 95%CI: 2.49–4.92, I2=49.1%, P=0.08) were the determinant factors for partograph use among obstetric acre providers in Ethiopia.Conclusion The overall pooled prevalence of partograph utilization among obstetric care providers was low. Therefore, supportive supervision, providing Basic Emergency Obstetric and Newborn Care training, on-the-job refresher training on partograph, and promoting midwifery profession are strongly recommended to increase the use of partograph.

“…Although the flash architecture has been used for very high speed ADC's, the disadvantage of requiring 2 N-1 comparators for N bits of resolution has limited the resolution of flash ADC's to less than 8 bits [2,3]. Folding structure effectively reduces the number of comparators by adding an analog pre-processing stage between the track and hold and the comparators.…”

A new technique for improving the performance of low-voltage folding ADC's by extending the input range is presented. It is shown that by using both PMOS and NMOS differential pairs in the folding blocks, the overall input voltage range of the ADC can be increased to rail-to-rail. A novel self-adjustment method is also introduced to compensate for the different input-output characteristics of PMOS and NMOS differential pairs. A low voltage 8-bit 80 MSample/s folding/interpolating ADC is then designed and fabricated in a 0.18 lm CMOS process. Operating with a supply voltage as low as 1.2 V, measurements show an INL below ±0.55 LSB, SNDR of 43.5 dB at 80 MHz Sampling Frequency and power dissipation of only 30 mW.
