n Contemporary studies indicate that teen pregnancy interferes with young women’s ability to graduate from high school and to enroll in and graduate from college. Conversely, planning, delaying and spacing births appears to help women achieve their education and career goals. Delaying a birth can also reduce the gap in pay that typically exists between working mothers and their childless peers ...

Adults are expert at recognizing faces, in part because of exquisite sensitivity to the spacing of facial features. Children are poorer than adults at recognizing facial identity and less sensitive to spacing differences. Here we examined the specificity of the immaturity by comparing the ability of 8-year-olds, 14-year-olds, and adults to discriminate houses differing in the spacing between fe...

Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30,...

As we move away from internal combustion engines to tackle climate change, the importance of hydrogen-powered vehicles and polymer electrolyte membrane fuel cell (PEMFC) technology has dramatically increased. In present study, aimed determine optimal configuration for power output a PEMFC system using computational fluid dynamics (CFD) modelling analyse variations primary serpentine design gas ...

Expansive soils shrink and swell with drying wetting cycles. The shrink-swell capacity of expansive can result in differential movement beneath foundations which is a very common cause foundation problems. Ribbed slab, often called waffle one the efficient inexpensive solutions for use under light structures resting on soils. This paper presents numerical analysis that used to calculate displac...

Abstract Optimization of all the process parameters for laser powder bed fusion (L-PBF), considering effects individual on Ti6Al4V fabricated parts, can be complex and challenging. Therefore, first time, three main variable (laser power, scan speed, hatch spacing) outcomes (surface roughness, bulk porosity, production rate parts) were studied in this work. Then, combination above-mentioned form...

To improve the responsivity of terahertz (THz) antenna-coupled bolometer, heater (load) resistance has to be increased suppress thermal conduction and realize larger temperature rise thermistor. Proper design antenna is therefore essential assure impedance matching between heater. From this viewpoint, a high-impedance folded-dipole (FDA) been studied numerically by finite element simulation. Th...
