PurposeCorona mortis is an abnormal arterial or venous anastomosis between the external iliac and the obturator system of vessels and may cause significant hemorrhage during pelvi-acetabular fracture surgeries, hernia repair and laparoscopic gynecological procedures. Previous studies have estimated a prevalence of corona mortis between 34% and 70%. This cadaveric study was conducted to estimate the prevalence of corona mortis in the North Indian population.Materials and MethodsTwelve cadavers (24 hemipelvises; 11 males and 1 female) with a mean age of 68 (range, 54–82) years were included in this study.ResultsCorona mortis was observed in 14 hemipelvises (58.3%). A total of 19 (79.2%) vascular anastomoses of diameter greater than 1 mm were observed; 5 hemipelvises (20.8%) had corona mortis on the right side, 9 hemipelvises (37.5%) on the left side and bilateral in 5 (41.7%) cases. Two hemipelvises (8.3%) had an arterial connection. An aberrant obturator artery was observed in 1 (4.2%) hemipelvis. A venous connection was found in 14 specimens (58.3% of hemipelvises). The average distance of the connecting vein from the symphysis pubis was 41 (35–70) mm. A vessel diameter of greater than 4 mm was observed in 4/24 (16.7%) of hemipelvises.ConclusionThe frequency of venous corona mortis was higher than arterial corona mortis and the majority (83.3%) were small calibre (<4 mm). The presentation pattern and the number of arterial or venous anastomoses were different in the majority of hemipelvises and dissimilar in both hemipelvises of the same cadaver in the majority of cases.
Parkland agroforestry woody species are prominent features in many landscapes worldwide, and their ecological, social and economic importance is widely acknowledged. It is the traditional agroforestry systems from different countries and is almost a universal occurrence in Ethiopia. This study was conducted in Gindeberet District, West Shoa Zone, Oromia Regional State, Ethiopia to assess the parkland agroforestry woody species composition, diversity, structure and biomass carbon. Woody species inventory was carried out on 103 plots (each, 50 m x10 0m) in the crop field laid along 7 transects. For woody species ≥ 5 cm DBH, measurements of DBH and tree height were taken. A total of 61 woody species belonging to 35 families were recorded. The study indicated that the woody species Shannon and Simpson diversity indices were higher at lowland than midland agro-ecology. The species richness was significantly different between the two agro-ecological zones (X 2 = 8.5, p = 0.003). This study showed low carbon storage potential in living biomass of woody species; it is recommended to develop a policy on the woody species management, conservation and regeneration to increase the carbon storage potential in living biomass of woody species.
<p><strong>Background</strong>. Altitude affects growth and distribution of plants and influences the impacts of other environmental factors on plant growth and development. <strong>Objective</strong>. The objective of this study was to investigate the effect of altitude on the growth performance and carbon sequestration potential of <em>Moringa stenopetala</em> in the Konso Zone, Southern Ethiopia. <strong>Methodology</strong>. The three sites that were selected for the study include Bayde (1300-1500 masl), Gamole (1501-1700 masl) and Fasha (1701-1900 masl). From each site three age classes (6-10 years, 11-15 years and 16-20 years) were selected for the study. Six farmers were selected from each location and three trees from each farmer’s land under each age class were selected for measuring height and diameter. Non-destructive method was used for estimation of biomass and carbon contents of different age groups. <strong>Results.</strong> The results indicate that growth performance (height, diameter, volume, biomass production) and carbon sequestration of <em>M. stenopetala</em> was significantly higher (p < 0.05) at lower altitude as compared to mid and high altitude. It was concluded that <em>M. stenopetala</em> tree within 6-10 age class can sequester 10.96 kg of carbon stock by capturing 40.17 kg of carbon dioxide, while for age class of 11-15 the value of carbon storage and carbon dioxidesequestered is27.87 kg and 102.20 kg respectively. Similarly maximum sequestration of carbon dioxide was recorded (42.31 Kg and 155.11 Kg respectively) for 16-20 age class. <sub>.</sub>The annual sequestration of carbon was found maximum for class 16-20 (8.62 kg) followed by 11-15 class (7.86 kg) and lowest for 6-10 class (5.02 kg). <strong>Implications</strong>. The findings of present study will be helpful in knowing the effect of age and altitudinal variation on carbon sequestration potential of <em>M. stenopetala.</em> <strong>Conclusions</strong>. It is concluded that carbon sequestration potential of Moringa decreases with altitude and increases with stand age.</p>
