Observations by the MACHO collaboration indicate that a signi cant fraction of the galactic halo dark matter may be in form of compact objects with masses M 0:5M . Identi cation of these objects as red or white dwarfs is problematic due to stringent observational upper limits on such dwarf populations. Primordial black hole (PBH) formation from pre-existing density uctuations is facilitated dur...
Biogenic amines (BA) are nitrogenous compounds that possess biological activity. The source of production is the microbial decarboxylation of amino acids. This compounds are found in various types of cheese. The aim of this work was to evaluate the BA content of some traditional cheeses in West Azerbaijan province Iran. For this purpose, 70 samples of Koopeh, 10 samples of Lighvan and 5 samples...
The author has presented an excellent paper describing considerations that went into the development and imple mentation of the subject facility. The use of some pho tographs in the paper was particularly helpful. The photo on p. 240 shows open structural members around the bottom of the key air pollution control elements. For very little additional capital cost, these areas can be en closed...
Nurse staffing and scheduling is a major health human resource issue currently facing healthcare organizations. To increase the capacity of healthcare organizations to address a variety of issues related to nurse staffing and scheduling, a mult-isite collaborative project was undertaken. The primary focus of this project was
Motivated by the GKM picture of the equivariant cohomol-ogy ring for a torus action on an orbifold we define one-skeletons and their corresponding rings, H(Γ, α). We prove that, under a mild gener-icity condition, such a ring is a free S(g *)−module, with generators given by Thom classes of flow-outs of the vertices. We also show that many interesting notions and results in symplectic geometry,...
My colleagues and I identified distant red galaxies (DRGs) with J −Ks>2.3 in the southern Great Observatories Origins Deep Surveys (GOODS–S) field. These galaxies reside at z∼1–3.5, (〈z〉≃2.2) and based on their ACS (0.4–1 μm), ISAAC (1–2.2 μm), and IRAC (3–8 μm) photometry, they typically have inferred stellar masses M&10 M⊙. Interestingly, more than 50% of these objects have 24 μm flux densiti...
Evidence from Electron Micrographs for the Passage of Material through Pores of the Nuclear Membrane
1. The nurse cells of Rhodnius possess nucleoli that stain with Heidenhain's hematoxylin but give a negative Feulgen reaction. In localized positions adjacent to the nuclear membrane are seen masses of material both within the nucleus and the adjoining cytoplasm that stain with Heidenhain's hematoxylin, but, like the nucleolus, give a negative Feulgen reaction. 2. Electron micrographs of the nu...
Here we report two novel red emission fluorescent probes for the highly sensitive and selective detection of monoamine oxidase (MAO) with large Stokes shift (227 nm). Both of the probes possess solid state fluorescence and can accomplish the identification of MAO on test papers. The probe MAO-Red-1 exhibited a detection limit down to 1.2 μg mL(-1) towards MAO-B. Moreover, the cleavage product w...
We prove that Weyl invariant theories of gravity possess a remarkable property which, under very general assumptions, explains the stability of flat space-time. We show explicitly how conformal invariance is broken spontaneously by the vacuum expectation value of an unphysical scalar field; this process induces general relativity as an effective long distance limit. We show that all ghost degre...
