Introduction Nature is a ubiquitous and powerful word that has been significant for understanding and endorsing forms of being and relationship throughout Western history. However, nature’s meanings—especially the social-relational significations that it carries—have varied over time, according to a range of contexts and “controlling images.”1 Nature is decidedly historical. Its myriad interpre...

Monotonically monolithic spaces were recently introduced by V.V. Tkachuk, and monotonically κ-monolithic spaces by O.Alas, Tkachuk, and R. Wilson. In this note we answer some of their questions by showing that monotonically ω-monolithic compact spaces must be Corson compact, yet there is a Corson compact space which is not monotonically ω-monolithic. We obtain a characterization of monotonic mo...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...

Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations that is referred as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than monolithic plates. In this article, laser formin...

general kind of encroachment of river is constructing a bridge on it. purpose of encroachment of river is occupation part of river and flood plain for constructing bridge. often being economical of bridge innovation affirmated that most of encroachment take place to river and flood plain, which this encroachment can be in form of embankment in flood plain of river or into the main bed of river ...

Monolithic silica columns and their use in high peak-capacity HPLC separations are reviewed. Monolithic silica columns can potentially provide higher overall performance than particle-packed columns based on the variable external porosity and variable through-pore size/skeleton size ratios. The high permeability of monolithic silica columns resulting from the high porosity is shown to be advant...

Poly (2-hydroxyethyl methacrylate) PHEMA monolithic cryogels were synthesized by free radical polymerization at -12°C for 18 hours and produced spongy, elastic and macroporous gel matrix. Scanning Electron Microscopy (SEM) measured structural properties of PHEMA monolithic cryogel matrix to visualize pore morphology. Mechanical properties of PHEMA monolithic cryogel such as storage modulus, com...

There is a huge development in mobile communications in Europe and consequently, the need for training engineering students in microwave design is growing. We present here some students projects aimed at designing microwave subsystems in MMIC and HMIC technology, for different wireless communications applications. They have been performed at LHOG/ENSERG (INPG), France. The capabilities and cons...
