Effective interactions for the nuclear shell model

Various perturbative and non-perturbative many-body techniques are discussed in this work. Especially, we will focus on the summation of so-called Parquet diagrams with emphasis on applications to finite nuclei. Here, the subset of two-body Parquet equations will be discussed. A practical implementation of the corresponding equations for studies of effective interactions for finite nuclei is outlined.Comment: 55 pages, latex, to appear in Advances in many-body theory, vol

Meat quality of hull calves fed only grass or only herbs for 8 weeks prior to slaughter matches that of concentrate-fed bull calves

The organic rules require that bull calves are raised outdoor at least 6 months a year in Denmark and are fed at least 60% roughage of the total diet. These rules are a constraint for an organic production of beef based on the bull calves born in the organic dairy herds because of extra labor costs, expected lower growth rate, difficulties in raising bull calves outdoor, possibly lower meat quality and lack of sufficiently high organic premium payment for the carcass. Thus, the bull calves are sold for conventional fattening. The supply of organic beef from young cattle is concomitantly very limited. However, in order to obtain the necessary higher payment for beef from organic-raised young cattle, it is important that consumers like the beef from grass- and herb-fed young cattle

Summary of space imagery studies in Utah and Nevada

The author has identified the following significant results. An enhanced enlargement of a S190B color image at a scale of 1/19,200 of the Bingham porphyry copper deposit has compared a geological map of the area with the space imagery map as fair for the intrusion boundaries and total lack of quality for mapping the sediments. Hydrothermal alteration is only slightly evident on space imagery at Bingham, but in the Tintic mining district and the volcanic piles of the Keg and Thomas ranges, Utah, hydrothermal alteration is readily mapped on color enlargements of S190B. Several sites of calderas were recognized and new ones located on space imagery. One of the tools developed is a mercury soil-gas analyzer that is becoming significant as an aid in locating hidden mineralized zones which were suggested from space imagery. In addition, this tool is a prime aid in locating and better delineating geothermal sites

Dispersive estimates for Schrodinger operators in dimensions one and three

We prove L^1 --> L^\infty estimates for linear Schroedinger equations in dimensions one and three. The potentials are only required to satisfy some mild decay assumptions. No regularity on the potentials is assumed.Comment: 20 pages. Corrected typos and improved explanatory remarks at the en

Measuring Risk: Political Risk Insurance Premiums and Domestic Political Institutions.

There is a renewed interest in political science on how political risk affects multinational corporations operating in emerging markets. Most existing studies suffer from data problems where researchers can only offer indirect evidence of the relationship between political institutions and political risk. In this paper I utilize a new data resource to explore how domestic institutions affect political risks for multinationals. Utilizing price data from political risk insurance agencies I test how domestic political institutions affect the premiums multinationals pay for coverage against 1) expropriations and contract disputes and 2) government restrictions on capital transactions. I find that constraints on politicians lead to marginally lower expropriation and transfer risks. Democracy, on the other hand, greatly reduces expropriation risk but has no impact on transfer risk.FDI, political risk, expropriation, insurance

Eating quality of Holstein bull calves fed only grass or purely herbs matches that of concentrate-fed veal calves

Organic meat production from Holstein calves born in dairy herds require that the bull calves are raised outdoor at least 6 months a year, and on large quantities of roughage in the diet. This study aimed at elucidating if Holstein bull calves fed either purely grass or purely herbs prior to slaughter would differ in meat quality traits, fatty acid composition and sensory profile and if they differed in quality aspects from concentrate-fed veal calves

Geology of Utah and Nevada by ERTS-1 imagery

Repetitive ERTS-1 imagery covering Utah and Nevada is studied as an aid in structural geology, mineral exploration, and limnological and hydrological aspects. Limnological features of algal blooms and varying biological activities in Utah Lake and the Great Salt Lake are grossly evident on the imagery with more subtle details detected on the different bands. Major structural breaks, lineages, or trends are abundant throughout the area of study. The correlation of positive aeromagnetic anomalies with the trends suggests near surface intrusive bodies, not yet exposed at the surface, that can be tested for possible associated mineralization by collecting soil-gas at the surface which is analyzed for mercury that is (1) apparently associated with mineralization, (2) escapes as a vapor, and (3) can be readily measured in extremely low amounts of less than 1 ppb by absorption
