TL;DR: This paper examined the role of skilled labor in the growth of total factor productivity and found that productivity growth was increasingly concentrated in high-skill industries during a unique ten-year period beginning in the early 1970s.
Abstract: This paper examines the role of skilled labor in the growth of total factor productivity. We use panel data from manufacturing industries to assess the extent to which productivity growth in yearly cross sections is tied to industry shares of skilled labor inputs. We find robust evidence that productivity growth was increasingly concentrated in high-skill industries during a unique ten-year period beginning in the early 1970s. We do not find any positive association of productivity growth with new capital investment.

TL;DR: The combined pretreatment using dilute sulfuric acid and aqueous ammonia on rice straw efficiently yielded fermentable sugar and achieved almost the same crystallinity index as that of α-cellulose.
Abstract: Use of lignocellulosic biomass has received attention lately because it can be converted into various versatile chemical compounds by biological processes. In this study, a two-step pretreatment with dilute sulfuric acid and aqueous ammonia was performed efficiently on rice straw to obtain fermentable sugar. The soaking in aqueous ammonia process was also optimized by a statistical method. Response surface methodology was employed. The determination coefficient (R2) value was found to be 0.9607 and the coefficient of variance was 6.77. The optimal pretreatment conditions were a temperature of 42.75°C, an aqueous ammonia concentration of 20.93%, and a reaction time of 48 h. The optimal enzyme concentration for saccharification was 30 filter paper units. The crystallinity index was approximately 60.23% and the Fourier transform infrared results showed the distinct peaks of glucan. Ethanol production using Saccharomyces cerevisiae K35 was performed to verify whether the glucose saccharified from rice straw was fermentable. The combined pretreatment using dilute sulfuric acid and aqueous ammonia on rice straw efficiently yielded fermentable sugar and achieved almost the same crystallinity index as that of α-cellulose.

TL;DR: In this article, the first time stepping method which combines a very low cost per time step with unconditional stability was introduced in 1999, and the present discussion starts with this method, and with an even more recent Crank-Nicolson-based split step method with similar properties.
