In knowledge economies, building technological capability is a continuous process and unarguably key to industrial policy development. Learning [by-doing in the industry] has been linked to a reduction in unit labor cost and overall production cost of goods and services. In this study, we comparatively studied the learning pattern of the Japanese manufacturing and service sector using industrial-leveldata. This study is perhaps the first attempt to comparatively study the productivity of the Japanese industry using the learning curve at the aggregate level. Looking back to almost 4 decade-long (19802017) of financial input-output data, we estimated the trend in technological learning using various learning models, calculated the annual progress ratios (via production function imputed in log-linear & cubic model) and revealed the dynamic technological learning across the two sectors at the aggregate level. This enabled us to identify years with good learning rates which are synonym...

This study focuses on characterization of hard-rock aquifers in South Western Côte d’Ivoire where previous quantitative hydrogeological studies were not enough. San Pedro is localized in South-Western Côte d'Ivoire where the basement is dominated by folded and fissured crystalline rocks. Several years ago, many drinking water supply initiatives were performed in this study area considering its particular geographical location and hydrological trumps. This study aims to contribute to the best knowledge of hydrogeological potentialities of this basement pointing to reduce doubtful quality surface water using. The database incorporated satellite radar image and reports of boreholes. The methodological approach was based on remote sensing, fracture characterizing, pumping tests reports and multivariate statistical analysis. Treatment of satellite image highlighted 271 fractures ranged between 2.11 and 39.37 km. Rock mass permeability due to fractures fluctuated between 2.35E-07 and ...

Environmental pollution and its impact on living organisms is worldwide problem. The pollutants discharged from the automobile activities are particulate matter, heavy metals (Pb and Cd), carbon dioxide, oxides of nitrogen and oxides producing toxic effects on plant growth. The other common effects are reduced yield of flowers, branch length, leaf area and reduction in seed germination percentage. This book chapter provide some information about the impact of auto exhaust pollution on plant growth. The importance of tree in the urban environment cannot be ignore. A number of studies on the effects of air pollution on tree growth have been carried out by researchers over the past many years in developed and in developing countries. Trees play an important role in maintaining the ecological balance, pollution reduction and lessening the burden of pollutant by absorbing pollutants. However, trees in urban cities are growing in a severe stressful environment due to incomplete burning of...

The Hausa potato (Solenostemon rotundifolius (Poir)) J. K. Morton is a tropical, multipurpose crop with different economic values. Its productivity is, however, low in terms of fresh tuber yield in the accessions available for cultivation in Nigeria. Consequently, many farmers are not encouraged to cultivate the crop, thereby limiting its popularity. This study was, therefore, designed to screen different accessions of the Hausa potato for productivity in the Jos-Plateau environment, Nigeria. The nine accessions (Manchok 1, Manchok 2, Bokkos 1, Bokkos 2, Bikka-Baban, Mujir, NRCRI, (White), Tukwak and Langtang) were laid out in a randomized complete block design with five (5) replications. Results indicate that percentage emergence, number of branches per plant, leaf area index (LAI), days to flowering, number of flowers per plant, relative growth rate, net assimilation rate, tuber length, tuber girth, root-top ratio, stand count at harvest, mean tuber weight, dry matter content and ...

Apple (Malus × domestica Borkh) occupies a significant place in the horticultural wealth of temperate zone. The growth and productivity of apple in Indian conditions can be optimised by replacing out-dated  depleted  standard  Delicious  cultivars  by  the  improved  high  yielding  cultivars  and  adopting standard clonal rootstocks instead of seedling stock in addition to improved management practices. The  present  investigation  was  undertaken  to  make  a  preliminary  assessment  for  studying  the performance of newly released apple cultivars viz, Lal Ambri, Sunhari, Shireen, Firdous and Akbar on clonal  rootstocks  M-9  and  MM-106. The  experiment  was  carried  out  at  the  Experimental  Farm  of SKUAST-Kashmir, and was laid out in a randomized block design with ten treatment combinations. ...
