Designing a building or a new urban space is collaborative work that involves several people with different backgrounds. To achieve consensus all participants in the process meet to discuss documents such as floor plans and sections. This paper reports on the progress of Space Pen, a new system to allow several users to draw on and annotate a three-dimensional representation of a building remot...

Agricultural soils can be affected in their ecological functions by in-field traffic of agricultural machinery. A three-factorial research design was carried out a field experiment to test the effect slurry tanker filling level (filled, half-filled, empty), tire inflation pressure (high: 300 kPa, low: 100 kPa), and ground covering (+cover crop, ?cover crop) on track soil penetration resistance ...

To help farmers in the mid hills of Nepal improve their crop management and rice yields, we conducted a study testing different nursery management options and their effect on grain yield and yield components under rainfed conditions. The experiment was conducted in a farmer’s field during the cropping season 2009 and 2010 at Sundarbazar, Lamjung, Nepal, using a 3-factor factorial RCB design wit...

Genetic diversity in 40 traditional boro rice genotypes was studied under irrigated condition through Mahalanobis D 2 statistic for grain yield and yield contributing characters. The genotypes were grouped into five clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the clusters. The intra-cluster distances were lower in all t...

Sewage sludge at the rate of 0, 40, 80, 120 and 240 t/ha showed that the number of filled grains per panicle, dry weight of grains and weight of 1000 grains of rice (Oryza sativa L.) were the significantly highest where 240 tons of sewage sludge per hectare was added. The contents of N, P, K, Ca, Mg, Fe, Cu, Zn and Pb in rice grains increased significantly with increasing rate of sewage sludge ...

To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...

Metamorphic devolatilization generates fluid and grain-scale porosity. Evidence for high fluid pressure indicates the devolatilization occurs under poorly-drained conditions. Under such conditions fluid expulsion is limited by the capacity of the reacted rocks to resist compaction or the rate at which deformation modifies the permeability of the overlying rocks. In the former case the compactio...

Genetic diversity of 40 traditional Bangladeshi rice genotypes was studied under rainfed condition through Mahalanobis D statistic for grain yield and yield contributing characters. The genotypes were grouped into six clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the genotypes of different clusters. The intra-cluster dist...

Nitrogen use efficiency is important for the development of sustainable agriculture. Plants have different transporters to facilitate nitrogen uptake and internal distribution. This study demonstrates that the peptide transporter OsNPF7.3 enhances nitrogen allocation and increases grain yield in rice. OsNPF7.3 is a member of the nitrate transporter 1/peptide transporter family (NPF) and is loca...
