CubeSat Measures World's First Ice Cloud Map to Support Climate Research

Virginia Diodes, Inc. received NASA SBIR Awards to fund research and development for a lesser developed region of the electromagnetic spectrumterahertz waves. Their work led to funding from NASA ESTO, and the resulting CubeSat (named IceCube) captured the worlds first ice cloud map, which will contribute to our understanding of Earths climat

The acceleration dilemma : can English law accommodate constructive acceleration?

Purpose – The aim of this paper is to explore the hypothesis that a contractor is entitled to payment for “constructive” acceleration implemented to avoid liquidated damages when denied a warranted time extension request by the employer or certifier under an English law construction contract. This claim is recognised in the US legal system, but not elsewhere. Design/methodology/approach – This paper adopts a “black letter” approach to reviewing the claim of constructive acceleration within the context of English and Commonwealth case law, from the perspective of a claimant contractor. Findings – The research presented in this paper concludes that whilst claims for constructive acceleration are unlikely to succeed in an English court on the basis of US law, a claim might be supportable on more orthodox common law grounds. These include implied instructions under the contract, breach of the contract based on the employer or certifier’s failure to operate the contract, mitigation of damages, unjust enrichment and tortious intimidation. Research limitations/implications – The focus of this paper is placed on English, Unites States, Canadian and Australasian case law. Practical implications – The range of potential legal grounds for constructive acceleration examined in this paper provides a toolkit for practitioners preparing to make or defend constructive acceleration claims. This paper also bring more clarity to a potential legal problem faced by practitioners in circumstances of significant tension and limited time. Originality/value – This paper provides a useful information source for practitioners faced with the prospect of advancing or defending constructive acceleration claims, and it provides a foundation for future related studies examining a wider scope of jurisdictions

Neutron inelastic scattering investigation of the magnetic excitations in Cu_2Te_2O_5X_2 (X=Br, Cl)

Neutron inelastic scattering investigations have been performed on the spin tetrahedral system Cu_2Te_2O_5X_2 (X = Cl, Br). We report the observation of magnetic excitations with a dispersive component in both compounds, associated with the 3D incommensurate magnetic order that develops below $T^{Cl}_{N}$=18.2 K and $T^{Br}_{N}$=11.4 K. The excitation in Cu_2Te_2O_5Cl_2 softens as the temperature approaches $T^{Cl}_{N}$, leaving diffuse quasi-elastic scattering above the transition temperature. In the bromide, the excitations are present well above $T^{Br}_{N}$, which might be attributed to the presence of a degree of low dimensional correlations above $T^{Br}_{N}$ in this compound

Technique for Estimating Trawl Efficiency in Catching Brown Shrimp (Penaeus aztecus), Atlantic Croaker (Micropogon undulatus) and Spot (Leiostomus xanthurus)

Mark-recapture experiments conducted in a small 17.5 ha lake in Barataria Bay, Louisiana, were used to estimate the efficiency of a 4.9-m (16-foot) otter trawl in capturing brown shrimp, Atlantic croaker, and spot in water 1.5 m deep. The trawl was observed to sweep an area 2.5 m in width. Trawl efficiency was determined to be approximately one-third to one-half for brown shrimp, one-fourth for Atlantic croaker, and only 6 percent for spot

Noninvasive Imaging Techniques in Islet Transplantation

Since the Edmonton trials, insulin independence can reproducibly be achieved after islet transplantation. However, a majority of patients resume insulin treatment in the first 5years after transplantation. Several mechanisms have been proposed but are difficult to pinpoint in one particular patient. Current tools for the metabolic monitoring of islet grafts indicate islet dysfunction when it is too late to take action. Noninvasive imaging of transplanted islets could be used to study β-cell mass and β-cell function just after infusion, during vascularization or autoimmune and alloimmune attacks. This review will focus on the most recent advances in various imaging techniques (bioluminescence imaging, fluorescence optical imaging, MRI, and positron emission tomography). Emphasis will be placed on pertinent approaches for translation to human practic
