Response modification factor (R-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. Relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. The present paper tries to evaluate the R-factors of conventional concentric braced frames (CBFs) and special moment frames (MRFs) in ...

Academic governance is an important dimension of institutional self-governance. This paper reports on the findings of a new study of university senates (academic councils) in Canadian universities in order to analyze changes in structure and in senate members’ perceptions of the structure and role of senates over the last decade. Following the basic design of a similar study in 2000, this study...

There is an increasing amount of research focussing on the transition to adulthood, a stage of the life cycle where young people face demanding life decisions, including completion of education, finding stable employment, and establishing their household and family. Whereas there is a well-developed literature on poverty among households in general, very little research has focused on poverty a...

This study links spatial and seasonal patterns of mortality of the hard clam, Mercenaria mercenaria (L.), in marine soft bottoms with the predation rates and habitat use of its main predator, the blue crab, Callinectes sapidus Rathbun. Patterns of predation on tethered juvenile clams exposed to the natural assemblage of predators were compared among different habitat types in fall and summer. B...

OBJECTIVES The aim of our study was to assess the health conditions and subjective symptoms of the inhabitants living in the base stations vicinity and to analyse the relationship between the complaints and level of exposure to electromagnetic fields (EMF). MATERIALS AND METHODS Our study was performed in housing estates located in five regions of Łódź. The electric field measurements were pe...

The Dutch government encourages innovative construction by subsidizing cohesive industrial, flexible and demountable building (IFD) pilot projects. Industrial building concerns the process-related aspects of production, robotization, mechanization, automation, prefabrication, communication, etc. Flexible building involves products that are made in accordance with customer’s wishes and the possi...

Midto high-rise buildings are often braced by slender reinforced concrete (RC) walls, which are coupled by RC floor diaphragms. In design it is typically assumed that the walls act independently and the design base shear demand is computed neglecting any compatibility forces between the walls. Pushover analysis of systems comprising walls of different lengths have, however, shown that large com...

0-group sea bass, Dicentrarchus labrax, colonize intertidal marsh creeks of Mont Saint Michel Bay, France, on spring tides (e.g., 43% of the tides) during flood and return to coastal waters during ebb. Most arrived with empty stomachs (33%), and feed actively during their short stay in the creeks (from 1 to 2 h) where they consumed on average a minimum of 8% of their body weight. During flood t...
