Integrating Islamic Cultural Identity Preservation in the Urban Fabric of the United States
Get PDFThe post-displacement phase of Islamic
migrants in the urban fabric of the United
States as a democratic country creates a
bicultural identity. Muslims have been
concerned about their identity preservation in
the United States and integrating in the
surrounding host community. This paper
concentrates on what type of solution I can
contribute, as an architect, to help in
integrating Muslim population specially
migrants at the post-displacement phase in the
urban fabric of the United States. How can an
architect help Muslim religious commonality
connect in the larger United States Context?
How do religious cultural buildings preserve
and integrate an Islamic cultural Identity in the
general cultural context of the United States?
In addition, how do public spaces located in
urban fabrics serve the integration process of
Islamic culture with the surrounding cultural
norms in order to be identified and well
accepted by the community? In order to
understand displaced minorities needs and
concerns interviews are conducted. A brief
explanation and analysis of the main Islamic
lifestyle and ancient cities planning is also an
important methodology in order to understand
the effectiveness of Islamic cultural buildings
at the United States in the identity
preservation process. Inspired by my own
personal experience I will explore and compare
three case studies: Saudi Arabia – a strict
Islamic country, Sudan – a moderate Islamic
country, and Columbus, Ohio – a western
urban society in the United States that is a
non-Islamic democratic country. An empirical
study will compare these three case studies
through the lens of democracy, diversity and
religion to explore how the Islamic Culture has
been reformed and how religious minorities are
preserving their own identities. My proposed
methodology in order to find a solution, as an
architect, is to create a loose public space
where all different cultures connect and
engage
Anatomic site of application of ice-nucleating active bacteria affects supercooling in the Colorado potato beetle (Coleoptera: Chrysomelidae)
Get PDFMost overwintering insects do not survive internal freezing and must avoid low temperatures or enhance the capacity of their body fluids to supercool to survive low temperature exposure. Recent reports have demonstrated that the application of ice-nucleating active microorganisms markedly diminishes supercooling. Topical application of as little as 20 ppm of a suspension of a freeze-dried preparation of the ice-nucleating active bacterium Pseudomonas syringae van Hall was sufficient to elevate the mean supercooling point of the overwintering adults of the Colorado potato beetle, Leptinotarsa decemlineata (Say), from −8.7 to −4.7°C. Previous reports have demonstrated that topical application of these biological ice nucleators to insects whose mouths have been sealed still reduces supercooling capacity; however, the anatomical route by which these agents make contact with body water is unclear. Application of the P. syringae suspension to the ventral abdomen did not significantly increase the supercooling point (−5.5°C) compared with beetles treated with the non-ice-nucleating active (control) bacterium Escherichia coli (Migula). However, application of the ice-nucleating agent to the thoracic spiracle, ventral cervix, or abdominal spiracle elevated supercooling point values above those of beetles treated on the ventral abdomen. These data are instructive in the development of methods for the use of ice-nucleating active microorganisms for the biological control of overwintering pests
Freezing impairment of male reproductive behaviors of the freeze-tolerant wood frog, Rana sylvatica.
Get PDFThe wood frog (Rana sylvatica), a temperate-zone anuran that overwinters within the frost zone, is adapted to tolerate the freezing and thawing of its tissues. Because the effects of freezing on complex neurobehavioral function are unknown and because R. sylvatica encounters subfreezing temperatures during its late-winter breeding season, we investigated the reproductive behaviors and physiology of male frogs after freezing (minimum body temperature, -2°C) and postthaw recovery (4°C). In tests simulating conditions at the breeding pool, these frogs, which otherwise behaved normally, exhibited reduced mate-searching effort and fewer assaults on mates and did not amplex females until 16-24 h after thawing. Although amplectic ability was ultimately restored in most frogs, they competed poorly for mates against never frozen controls. Further study suggested that the level of behavioral impairment depends on the severity of the freezing exposure. During freezing, tissues accumulated large quantities of the cryoprotectant glucose and desiccated extensively, responses that promote freezing survival. Freezing also caused marked hydroosmotic and metabolic perturbations, which may have impaired neurobehavioral function, perhaps by interfering with the processing of audio, visual, and tactile stimuli. Individuals that encounter subfreezing temperatures shortly before arriving at the breeding pools may incur reduced reproductive success
