Electronic state spectroscopy by high-resolution vacuum ultraviolet photoabsorption, He(I) photoelectron spectroscopy and ab initio calculations of ethyl acetate

Abstract: The high-resolution vacuum ultraviolet photoabsorption spectrum of ethyl acetate,C4H8O2, is presented over the energy range 4.5−10.7 eV (275.5−116.0 nm). Valence and Rydberg transitionsand their associated vibronic series observed in the photoabsorption spectrum, have beenassigned in accordance with new ab initio calculations of the vertical excitation energiesand oscillator strengths. Also, the photoabsorption cross sections have been used tocalculate the photolysis lifetime of this ester in the upper stratosphere(20−50 km). Calculationshave also been carried out to determine the ionisation energies and fine structure of thelowest ionic state of ethyl acetate and are compared with a newly recorded photoelectronspectrum (from 9.5 to 16.7 eV). Vibrational structure is observed in the firstphotoelectron band of this molecule for the first time

Protein Efficiency Ratio and Amounts of Selected Nutrients in Mechanically Deboned Spent Layer Meat

Three types of mechanically deboned spent layer meat (MDSL) were found to have adjusted protein efficiency ratios (PER) equivalent or superior to a standard (casein) diet. These same materials proved to be good sources of calcium, iron and zinc. Percentage protein ranged from 15.39 for MDSL from whole spent layers to 16.55 for MDSL from spent layer frames with wings. Fat levels were highest for whole birds (20.41%) and lowest for frames without skin (16.84%). High levels of unsaturated fatty acids were found to be associated with these products.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71440/1/j.1365-2621.1982.tb10143.x.pd

What Makes Logistics Integration More Effective? Governance from Contractual and Relational Perspectives

Third-party logistics (3PL) user-provider integration is attracting increasing attention from both academics and practitioners. However, it remains unclear how best to adopt governance mechanisms to safeguard 3PL user-provider integration (e.g., information sharing and process coordination). Based on transaction cost economics and social exchange theory, this study examined the individual and joint effects of contractual (e.g., detailed contracts and contract application) and relational governance (e.g., trust and relational norms) on 3PL user-provider integration for operational performance. We conducted a survey involving 247 3PL service users and analyzed the conceptual model using the method of structural equation modeling. The results showed that process coordination improved operational performance, while information sharing alone did not significantly improve operational performance but complemented the role of process coordination in improving operational performance. In addition, having detailed contracts was positively related to process coordination, while contract application was positively related to information sharing. Trust was not significantly related to information sharing or process coordination, while relational norms were positively related to both. Finally, three joint effects on 3PL user-provider integration were found. Two of them were substitutional (detailed contracts and relational norms; contract application and trust), and one was complementary (detailed contracts and trust). This study makes several theoretical contributions and provides novel guidelines for 3PL relationship development
