Iowa 2088 Summer Storms After-Action Report Final, April 27, 2009

In the summer of 2008, the state of Iowa suffered from a series of severe storms that produced tornadoes and heavy rainfall, which resulted in widespread flooding. The Summer Storms1 lasted from late May through mid-August, with the most intense storms occurring over a month-long period from May 25 to June 25. The Summer Storms exacted a major human and economic toll on Iowa, resulting in 18 fatalities and 106 injuries, forcing the evacuation of approximately 38,000 Iowans, and impacting 21,000 housing units. Iowa’s public and private sectors suffered significant monetary damages. Eighty-six of the ninety-nine counties in the state were included in the Governor’s disaster declarations. Presidential disaster declarations made residents in 84 counties eligible for Public Assistance and 78 counties for Individual Assistance. The Rebuild Iowa Advisory Commission estimated $798.3 million in damages to publicly owned buildings and infrastructure, including damages of $53 million to public transportation and $342 million to public utilities. The 2008 Summer Storms presented unique coordination challenges for the Iowa Homeland Security and Emergency Management Division (HSEMD) and the State Emergency Operations Center (SEOC). These challenges arose from three interrelated factors: the large number of local jurisdictions and areas impacted, the prolonged period of time that response operations were conducted, and the increasing complexity of overall response operations. These events caused the SEOC to coordinate response, mitigation, recovery, and preparedness operations simultaneously. HSEMD and the SEOC implemented a variety of measures to enhance their ability to coordinate operations and assistance to localities. The SEOC expanded its organizational structure, implemented innovative techniques, and incorporated new partners into its activities. These steps enabled HSEMD and SEOC to coordinate operations more effectively, which undoubtedly helped save lives and property, while mitigating the effects of the 2008 Summer Storms.

Derivation of the gauge-invariant action for open and closed free bosonic string field theories

The gauge-invariant actions for open and closed free bosonic string field theories are obtained from the string field equations in the conformal gauge using the cohomology operations of Banks and Peskin. For the closed-string theory no restrictions are imposed on the gauge parameters.

Place des antiarthrosiques symptomatiques d'action lente dans l'arthrose (sulfate de chondroïtine, glucosamine, acide hyaluronique) [Role of slow-acting anti-arthritic agents in osteoarthritis (chondroitin sulfate, glucosamine, hyaluronic acid)].

Osteoarthritis (OA) is one of the major causes of pain and of outpatient's clinics. 15 years ago, physiopathology of OA and its potential therapeutic targets were announced to be better understood, but the results of therapeutic trials were finally not as convincing as expected. Slow Acting Drugs (SADs) are part of the treatments evaluated in OA. Even if evidence based medicine is low, positive effects of SADs have been observed. We can reasonably propose these treatments for a short test period. It can sometimes enable us to decrease the dosage of others treatment such as NSAIDs. In any case, the physician must properly inform the patient about products available in Switzerland and must be aware of degrees of purity and costs of the products available on the intemet.

Role of the GNOM gene in Arabidopsis apical-basal patterning--From mutant phenotype to cellular mechanism of protein action.

How the apical-basal axis of polarity is established in embryogenesis is still a mystery in plant development. This axis appeared specifically compromised by mutations in the Arabidopsis GNOM gene. Surprisingly, GNOM encodes an ARF guanine-nucleotide exchange factor (ARF-GEF) that regulates the formation of vesicles in membrane trafficking. In-depth functional analysis of GNOM and its closest relative, GNOM-LIKE 1 (GNL1), has provided a mechanistic explanation for the development-specific role of a seemingly mundane trafficking regulator. The current model proposes that GNOM is specifically involved in the endosomal recycling of the auxin-efflux carrier PIN1 to the basal plasma membrane in provascular cells, which in turn is required for the accumulation of the plant hormone auxin at the future root pole through polar auxin transport. Thus, the analysis of GNOM highlights the importance of cell-biological processes for a mechanistic understanding of development.

Collective states of 3He clusters

The monopole (L=0) and quadrupole (L=2) strength distributions in normal 3He clusters are calculated within the random-phase approximation. We use a phenomenological, zero-range 3-3He interaction to generate the Hartree-Fock single-particle spectrum and the residual particle-hole interaction. The evolution of the collective modes with the number of atoms in the cluster is discussed.

Collective and single-particle excitations of a trapped Bose gas

The density of states of a Bose-condensed gas confined in a harmonic trap is investigated. The predictions of Bogoliubov theory are compared with those of Hartree-Fock theory and of the hydrodynamic model. We show that the Hartree-Fock scheme provides an excellent description of the excitation spectrum in a wide range of energy, revealing a major role played by single-particle excitations in these confined systems. The crossover from the hydrodynamic regime, holding at low energies, to the independent-particle regime is explicitly explored by studying the frequency of the surface mode as a function of their angular momentum. The applicability of the semiclassical approximation for the excited states is also discussed. We show that the semiclassical approach provides simple and accurate formulas for the density of states and the quantum depletion of the condensate.

Temperature-induced resonances and Landau damping of collective modes in Bose-Einstein condensed gases in spherical traps

Interaction between collective monopole oscillations of a trapped Bose-Einstein condensate and thermal excitations is investigated by means of perturbation theory. We assume spherical symmetry to calculate the matrix elements by solving the linearized Gross-Pitaevskii equations. We use them to study the resonances of the condensate induced by temperature when an external perturbation of the trapping frequency is applied and to calculate the Landau damping of the oscillations.

Molecular mechanisms of action of herbal antifungal alkaloid berberine, in Candida albicans.

Candida albicans causes superficial to systemic infections in immuno-compromised individuals. The concomitant use of fungistatic drugs and the lack of cidal drugs frequently result in strains that could withstand commonly used antifungals, and display multidrug resistance (MDR). In search of novel fungicidals, in this study, we have explored a plant alkaloid berberine (BER) for its antifungal potential. For this, we screened an in-house transcription factor (TF) mutant library of C. albicans strains towards their susceptibility to BER. Our screen of TF mutant strains identified a heat shock factor (HSF1), which has a central role in thermal adaptation, to be most responsive to BER treatment. Interestingly, HSF1 mutant was not only highly susceptible to BER but also displayed collateral susceptibility towards drugs targeting cell wall (CW) and ergosterol biosynthesis. Notably, BER treatment alone could affect the CW integrity as was evident from the growth retardation of MAP kinase and calcineurin pathway null mutant strains and transmission electron microscopy. However, unlike BER, HSF1 effect on CW appeared to be independent of MAP kinase and Calcineurin pathway genes. Additionally, unlike hsf1 null strain, BER treatment of Candida cells resulted in dysfunctional mitochondria, which was evident from its slow growth in non-fermentative carbon source and poor labeling with mitochondrial membrane potential sensitive probe. This phenotype was reinforced with an enhanced ROS levels coinciding with the up-regulated oxidative stress genes in BER-treated cells. Together, our study not only describes the molecular mechanism of BER fungicidal activity but also unravels a new role of evolutionary conserved HSF1, in MDR of Candida.

Collective spin excitations of alkali-metal clusters

The response function of alkali-metal clusters, modeled as jellium spheres, to dipole (L=1) and quadrupole (L=2) spin-dependent fields is obtained within the time-dependent local-spin-density approximation of density-functional theory. We predict the existence of low-energy spin modes of surface type, which are identified from the strength function. Their collectivity and evolution with size are discussed.
