- Local-scale turnpike roads in nineteenth-century Kentucky
By the nineteenth century's second decade, many state legislatures espoused internal improvements, but their road-building efforts centered largely on constructing a limited number of regional-scale, trans-state routes, and roads intended to link county seats, not on an extensive network of local-scale, farm-to-market roads that would provide farmers' direct linkage to commercial towns 10 If
- Engineering | Journal | ScienceDirect. com by Elsevier
The official journal of the Chinese Academy of Engineering and Higher Education Press Engineering is an international open-access journal that was launched by the Chinese Academy of Engineering (CAE) in 2015 Its aims are to provide a high-level platform where cutting-edge advancements in engineering R D, current major research outputs, and key achievements can be disseminated and shared; to
- Separation of amine-insoluble species by flotation with nano and . . .
Amines are organic compounds widely used in the industry The consumption of these reagents as flotation agents (collectors) in iron and potassium mining is growing fast in Brazil (Araujo et al , 2010) In the reverse flotation of iron ore the process consists of a selective separation of quartz silicates particles (gangue material) from the valuable iron oxides
- Propagation and quantification of uncertainty in the vulnerability . . .
The experiences of previous earthquakes, such as the Northridge earthquake in California in 1994, the Kobe earthquake in Japan in 1995, and the earthquake off the coast of central Chile in 2010, reveal that bridges with irregularities in their configurations have a higher chance of collapsing or sustaining severe damage than bridges constructed with typical configurations [13], [14], [15], [16]
- Insights into the modeling of adsorption isotherm systems
In general, an adsorption isotherm is an invaluable curve describing the phenomenon governing the retention (or release) or mobility of a substance from the aqueous porous media or aquatic environments to a solid-phase at a constant temperature and pH [32], [33] Adsorption equilibrium (the ratio between the adsorbed amount with the remaining in the solution) is established when an adsorbate
- Production quality and human factors engineering: A systematic review . . .
Humans are an essential part of OS that are difficult to replicate (unlike technology) and hence improving their performance could eventually lead to sustainably competitive OS (Ahmad and Schroeder, 2003; Onyema, 2014) While there is a whole discipline of Human Factors (HF) (to be considered as synonymous with Ergonomics), which is devoted to optimizing the design of the human-system
- Insights into the modeling of adsorption isotherm systems
In the endeavor to explore novel adsorbents in accessing an ideal adsorption system, it is essential to establish the most appropriate adsorption equilibrium correlation [21], which is indispensable for reliable prediction of adsorption parameters and quantitative comparison of adsorbent behavior for different adsorbent systems (or for varied experimental conditions) [22], [23]
- Hydrogels for tissue engineering: scaffold design variables and . . .
The field of tissue engineering has developed to meet the tremendous need for organs and tissues [1], [2], [3], [4] In the most general sense, tissue engineering seeks to fabricate, living replacement parts for the body [5] The necessity of tissue engineering is illustrated by the ever-widening supply and demand mismatch of organs and tissues for transplantation (Fig 1) [6]
