A global low order spectral model designed for climate sensitivity studies

A two level, global, spectral model using pressure as a vertical coordinate is developed. The system of equations describing the model is nonlinear and quasi-geostrophic. A moisture budget is calculated in the lower layer only with moist convective adjustment between the two layers. The mechanical forcing of topography is introduced as a lower boundary vertical velocity. Solar forcing is specified assuming a daily mean zenith angle. On land and sea ice surfaces a steady state thermal energy equation is solved to calculate the surface temperature. Over the oceans the sea surface temperatures are prescribed from the climatological average of January. The model is integrated to simulate the January climate

Emergent Form from Structural Optimisation of the Voronoi Polyhedra Structure

In the course of the exploration of computational means in the architectural design process, in order to investigate more complex, adaptive geometries, the Voronoi diagram has recently gained some attention, being a three-dimensional space-filling structure which is modular but not repetitive. The project looks at the Voronoi diagram as a load-bearing structure, and whether it can be useful for structural optimisation. Hereby the edges of the Voronoi polyhedra are regarded as structural members of a statical system, which then is assessed by structural analysis software. Results seem to indicate that the Voronoi approach produces a very specific structural as well as spatial type of order. Through the dislocation of the Voronoi cells, the statical structure becomes more complex through emergent topology changes, and the initially simple spatial system becomes much more complex through emerging adjacencies and interconnections between spaces. The characteristics of the emerging form, however, lie rather in the complexity how shifted spaces and parts are fitted together, than in a radical overall emergent geometry. Spatially as well as a structurally, the form moves from a simple modular repetitive system towards a more complex adaptive one, with interconnected parts which cannot stand alone but rather form an organic whole

Acclimatization to heat in humans

The responses and mechanisms of both natural and artificial acclimatization to a hot environment in mammals are addressed with specific reference to humans. The purpose is to provide basic information for designers of thermal protection systems and countermeasures for astronauts during intra- and extravehicular activity. Areas covered are energy metabolism, thermal balance at rest and during exercise, water and electrolyte balance during exercise and immobilization, and heat diseases

Acclimatization to cold in humans

This review focuses on the responses and mechanisms of both natural and artificial acclimatization to a cold environment in mammals, with specific reference to human beings. The purpose is to provide basic information for designers of thermal protection systems for astronauts during intra- and extravehicular activities. Hibernation, heat production, heat loss, vascular responses, body insulation, shivering thermogenesis, water immersion, exercise responses, and clinical symptoms and hypothermia in the elderly are discussed

Partial constraint singularities in elastic rods

We present a unified classical treatment of partially constrained elastic rods. Partial constraints often entail singularities in both shapes and reactions. Our approach encompasses both sleeve and adhesion problems, and provides simple and unambiguous derivations of counterintuitive results in the literature. Relationships between reaction forces and moments, geometry, and adhesion energies follow from the balance of energy during quasistatic motion. We also relate our approach to the balance of material momentum and the concept of a driving traction. The theory is generalizable and can be applied to a wide array of contact, adhesion, gripping, and locomotion problems.Comment: edited tex

Salve Regina University Hydroponic Growing Guide: Dolores Chive

This Salve Regina Hydroponic Growing Guide describes the process of hydroponically growing Dolores Chives (Allium schoenoprasum) in a tower system. This grow guide is based on the research project completed by third year student, Hanna Lloyd, through the Hydroponic Practicum, during the 2023 spring semester. Dolores chives are an aromatic herb which grow as tall, thin, green, leaves. Chives thrive under direct light with nutrient-rich water, and propagate under grow lights in approximately 15 days. When grown in a hydroponic tower, chives can reach up to 12-20 inches in length. The following guide provides information on optimal pH, optimal nutrient levels, and optimal light/water exposure for growing chives hydroponically, as well as recommendations for future growers.https://digitalcommons.salve.edu/hydroponic_center/1004/thumbnail.jp

Newsrooms and Social Media

The purpose of this research is to identify how local newspapers and newsrooms are converging to social media. An Ohio newspaper, The Post volunteered to have its Facebook Pages analytics studied over the course of two months, August through September. A constructed week was formed and four of the company’s Facebook Pages were analyzed. The study intends to examine the current social media position of The Post, assess the potential or areas of growth, and create a best practices manual to propel the selected newspaper’s social media accounts forward. Unlike traditional newspaper consumers, social media users tend to gather their news towards the weekend, more specifically on Fridays, the findings suggest. To further advance the credibility of the data analysis, social media editors Mark Smith from The Washington Post, Dan Kadar of The Akron Beacon Journal, and Amanda Harnocz from The Cleveland Plain Dealer, were interviewed to determine other companies’ social media practices. These interviews informed that content and post strategy directly impact success of a given social media post. In addition, the research looks toward the importance of teaching journalists to think about how the story would be crafted for social media while writing their given beats

Falling through the Cracks: Missouri Amends Its Felon Firearm Possession Statute

In early September 2007, police in Cape Girardeau, Missouri, arrested a previously convicted felon whom they discovered drivinp with a loaded gun, a magazine of ammunition, and a stun gun in his vehicle. The man, who was convicted in Illinois in 2000 for sexual abuse and failing to register as a sex offender, was later released after police determined that his possession of the gun, ammunition, and the stun gun did not violate Missouri law. This incident inspired Cape Girardeau County Prosecuting Attorney H. Morley Swingle to lobby for changes to Missouri\u27s statute prohibiting some felons from possessing firearms
