A static limit analysis approach is proposed for assessing the collapse capacity of axisymmetric masonry domes subject to horizontal forces. The problem formulation based on sound theoretical framework provided by classical statics shells. After introducing shell stress resultants dome mid-surface, integral equilibrium equations are enforced its typical part. Heyman’s assumptions infinite compr...
BACKGROUND In the majority of health centers in Ethiopia, the severity of falciparum malaria has been determined by parasitemia alone. However, it has been suggested that the use of peripheral infected RBC counts as an indicator of disease severity by itself is insufficient. Therefore, this study was performed to assess the severity of falciparum malaria infection in three Ethiopian localities ...
Managing trade-offs through gene regulation is believed to confer resilience to a microbial community in a fluctuating resource environment. To investigate this hypothesis, we imposed a fluctuating environment that required the sulfate-reducer Desulfovibrio vulgaris to undergo repeated ecologically relevant shifts between retaining metabolic independence (active capacity for sulfate respiration...
Declines in pollinator populations may harm biodiversity and agricultural productivity. Little attention has, however, been paid to the systemic response of mutualistic communities to global environmental change. Using a modelling approach and merging network theory with theory on critical transitions, we show that the scale and nature of critical transitions is likely to be influenced by the a...
Methods to improve bearing capacity of footing resting of collapsing soil can, in fact, take two approaches, improving soil strength properties and intrusion of reinforcing sorces into soil. The footing is modeled by a square steel plate 0.1 by 0.1 m. The footing is loaded as to have a stress of 40 kPa and settlement is receded in dry and in soaking conditions. Two depths of the geo-mesh reinfo...
The answer may be yes. A discrete model of energy-conserved wavefunction collapse is proposed. It is shown that the model is consistent with existing experiments and our macroscopic experience.
Many strucrural engineers are surprised to learn that the In~rnotional Building Code (IBC, 2009) requires the roof structure to be engineered for standing water weight in the vicinity of the drains and scuppers regardless of roof slope. In addition, some low-slope roofs also require special attenlion for water weight and stiffness for safety against ponding failures or protection against accele...
