There are many ways to describe the technology of a firm, such as, production functions, graphs, or systems of inequalities. But in mathematical term, these representations can all be expressed as a set. The firm uses and produces a total ofmcommodities. ...
Are the locations in the brain of language regions related to the fact that most human languages employ speech? That is, Wernicke's area is near auditory cortex, and Broca's area is just anterior to the mouth area of motor cortex. Not all linguistic functions, however, use audition as inp...
Education Production Functions: Developed Countries Evidence | Eric A. Hanushek EA Hanushek 被引量: 28发表: 2010年 Education and agricultural productivity: Evidence from Uganda Existing evidence on the impact of education on agricultural productivity in Africa is mixed, with estimates usually insignificant...
While such a stimulus is usually considered suitable mainly for small (and new) technology-based firms, our evidence suggests that larger firms could also benefit from it, since they are not constrained by problems of efficiency in production. Sector-specific effects are also important when we ...
The function \(\varPhi (x,k^2)\) is an auxiliary quantity for which the BK equation has a simple form with local nonlinear term as will be shown below. The explicit relation between the two functions \({\mathcal F}(x,k^2)\) and \(\varPhi (x,k^2)\). is...
Using console.log() or console.error() to print log messages to the terminal is common practice in development. But these functions are synchronous when the destination is a terminal or a file, so they are not suitable for production, unless you pipe the output to another program....
Nodulation response to inoculation in the presence of high numbers of native rhizobia population is an indication that, the tested rhizobium strains are more competitive. The results have shown the need for inoculation of appropriate rhizobium strains in all the study locations. Rhizobium strains TAL_...
Biofuels are one part of a set of solutions to minimize emissions of greenhouse gases. Investments should be focused on crops with the highest favourable greenhouse gas balances for the lowest social and environmental costs for climate change [56]. However, scientific research has shown that ...
There are mainly three fundamental functions, namely, production control, maintenance scheduling and quality control, which have great impacts on production performance. Production control aims to achieve favourable performance by predicting, planning and scheduling production activities with the constraints of...
Furthermore, as shown in Fig. 3d, e, the work functions (Φ) of CdS (200) crystal facet and NiPS3 (002) crystal facet are, respectively, calculated to be 4.06 and 5.02 eV. These results also support the electron extraction from CdS to NiPS3 at the interface after combining CdS and ...
