The study was conducted at Mundopasha, Wazirpur, Barisal during Rabi season of 2017 for testing, adoption and popularization of different conservation machinery (CA) such as zero till planter (ZT), strip till planter (ST), bed planter (BP) and power tiller operated seeder (PTOS) along with conventional tilling and of sowing method for planting of mungbean (BARI Mung-6). The soil type was loamy-sand with bulk density 1.41 g/cc. The effective field capacities of ZT, ST, BP, PTOS and power tiller were found to be 0.104, 0.109, 0.084, 0.109, and 0.074 ha/h, respectively. The field efficiency of ZT, ST, BP, PTOS and power tiller were estimated as 74.68, 76.47, 75.84, 78.16 and 71.52%, respectively. Significantly the highest mungbean grain yields were found from ZT and ST planted plots than those of other plots. Significantly the lowest grain yield was obtained from conventional tillage and broadcasting method. The highest benefit cost ratio (BCR) was obtained from ST planted (2.60) and zero till planted (2.40) mungbean followed by PTOS (2.20), conventional tillage cum broadcasting (1.88) and bed planting (1.82) methods. The lowest BCR was found from traditional tillage and manual line sowing method (1.61) of mungbean. CA planting system saved about 50% planting cost and reduced about 76% carbon dioxide emission. Based on the fuel consumption, grain yield and BCR, ZT planter and the strip till planter may be recommended in Barisal region for cultivation of mungbean.

Millions of people from different countries depend on groundwater, which might contain elevated levels of unhygienic constituents. Poor quality of drinking water in many countries has been forcing people to use bottled water. In the present study, groundwater samples were collected in November 2014 leading to twenty-nine analysis of groundwater samples. The primary objective of this paper is to study the selected groundwater quality parameters as an establishment of preliminary baselines on groundwater constituents. A total of twenty nine water samples were collected (fourteen and fifteen samples from North and South regions of Zanzibar Island respectively. Physical parameters (Turbidity, oxidation-reduction potential ORP, Eh, pH, total dissolved soild TDS, salinity, and Electrical conductivity (EC) were determined in situ using Horiba multiparameters digital meters. Analysis of anions (NO3-, Br- , SO42-, F-, NO2-) was carried out using Ion chromatography (IC). Nitrite and nitrate for some water were below detection limit (BDL) The order of relative abundance for anions in samples collected at Northern region of Zanzibar Island, was NO3- > Br- > SO42- > F- > NO2- , while for the Southern region the order was NO3- >Br- > NO2- > SO42- > F- . In both regions, the orders for other parameters were; Turbidity > pH > salinity; and EC >TDS > ORP > Eh. Almost all the measured parameters were within the WHO guidelines for drinking water. However, for nitrate and bromide, the percentage that exceeded the WHO limit was 7%, and 10.3% respectively. Based on toxicological perspective, although few samples had concentrations above groundwater quality criterion it is fundamental to estimate the intake by humans through the drinking water pathways.

Cesarean sections (CS) are one of the most commonly performed surgical procedures worldwide. There is great variability in the percentage of cesarean sections between countries, varying from 3% to 42.9%5. In the US, approximately 32% of deliveries occur through a cesarean section. Overall, a drastic increase in cesarean section rate has been reported reaching its highest level at the present time. In Brazil, considering the types of births by live births from 2006 to 2016, the national percentage of cesarean section was 52.37%. The variability in this percentage can still be perceived within Brazilian territory. The highest cesarean rate occurred in the Southern region, representing 58.33% of births, while the lowest rate occurred in the Northern region, with 41.79%. It is possible to see the steady increase in the percentage of CS over time, from 45.01% in 2006 to 55.39% in 2016.
