Molecular diversity and natural products [PDF]

open access: yesMolecular Diversity, 2011
Natural products have long represented the mayor source ofdrugs,andeventodaytheyremainattheforefrontofpharma-ceutical research. Between 1982 and 2002, 28% of the NewChemicalEntities(NCE)approvedbytheFDAwerenaturalproducts or derivatives of natural products [1], a very highshare, since only less than 1% of the characterized organiccompounds are of ...

Linguistic Diversity and Workplace Productivity [PDF]

open access: yesSSRN Electronic Journal, 2019
Abstract We study the importance of linguistic diversity in the workplace for workplace productivity. While cultural diversity might improve productivity through new ideas and innovation, linguistic diversity might increase communication costs and thereby reduce productivity.

Cultivar diversity as a means of ecologically intensifying dry matter production in a perennial forage stand [PDF]

open access: yes, 2014
The relationship between genotypic diversity and productivity has not been adequately explored in perennial forage production systems despite strong theoretical and empirical evidence supporting diversity\u27s role in ecosystem functioning in other ...

Dynamic Product Diversity [PDF]

open access: yesThe Journal of Industrial Economics, 2016
This paper examines the frequency of new product introductions in monopoly markets where demand is subject to temporary satiation. Consumers' taste for diversity is satisfied over time as new varieties are introduced to the market. If two varieties are introduced in consecutive periods then they become imperfect substitutes and the firm has an ...

Monitoring and population changes of Tuta absoluta (Meyrick, 1917) on tomato under greenhouse conditions in an arid expanse of south-eastern Algeria

open access: yesActa Agriculturae Slovenica, 2020
The population changes of Tuta absoluta was surveyed during three growing seasons in greenhouse tomatoes in Biskra. Introduced in 2009 for the first time, it seems to be well established on tomato crops in Biskra; while their natural enemies remained ...

Zymomonas diversity and potential for biofuel production [PDF]

open access: yesBiotechnology for Biofuels, 2021
Abstract Background Zymomonas mobilis is an aerotolerant α-proteobacterium, which has been genetically engineered for industrial purposes for decades. However, a comprehensive comparison of existing strains on the genomic level in conjunction with phenotype analysis has yet to be carried out.

Spatial and temporal variation in crop diversity in agroforestry homegardens of southern Ethiopia [PDF]

open access: yes, 2001
A key assumption in many homegarden studies is that homegardens are ecologically and socio-economically sustainable due to their species diversity. The precise relation between diversity and sustainability is still heavily debated, however.

Inequality, Market Power, and Product Diversity [PDF]

open access: yesSSRN Electronic Journal, 2003
We analyze a macroeconomic model of monopolistic competition in which consumers earn unequal incomes. When preferences are nonhomothetic, the distribution of income affects equilibrium markups and equilibrium product diversity.
