THE IMPACT OF SALES CHANGES ON AGRIBUSINESS PAYROLLS

Agribusiness firms face substantial market risk associated with variations in farm production, output and input prices, exchange rates, and other factors. Some of the risk faced by agribusiness is passed through to the employees of the firm and to the communities where the firms are located, as employment levels are changed in response to these variations. An econometric analysis of the transmission of sales changes into payroll changes was performed for a sample of Georgia agribusiness firms. Transmission elasticities were found to be affected by firm type, size, age, and by the degree of use part-time employees.Agribusiness, Employment stability, Labor, Labor and Human Capital, Agribusiness,

HISTOLOGICAL STUDIES OF BREWERY SPENT GRAINS IN DIETARY PROTEIN FORMULATION IN DONRYU RATS

The increasing production of large tonnage of products in brewing industries continually generates lots of solid waste which includes spent grains, surplus yeast, malt sprout and cullet. The disposal of spent grains is often a problem and poses major health and environmental challenges, thereby making it imminently necessary to explore alternatives for its management. This paper focuses on investigating the effects of Brewery Spent Grain formulated diet on haematological, biochemical, histological and growth performance of Donryu rats. The rats were allocated into six dietary treatment groups and fed on a short-term study with diet containing graded levels of spent grains from 0, 3, 6, 9, 12 and 100% weight/weight. The outcome demonstrated that formulated diet had a positive effect on the growth performance of the rats up to levels of 6% inclusions, while the haematological and biochemical evaluation revealed that threshold limit should not exceed 9% of the grain. However, the histological study on the liver indicated a limit of 3% inclusion in feed without serious adverse effect. Thus invariably showing that blend between ranges 1-3% is appropriate for the utilization of the waste in human food without adverse effect on the liver organ. The economic advantage accruing from this waste conversion process not only solves problem of waste disposal but also handle issues of malnutrition in feeding ration

Following the relaxation dynamics of photoexcited aniline in the 273-266 nm region using time-resolved photoelectron imaging

Scanning tunnelling microscopy (STM) and Auger electron spectroscopy (AES) have been used to investigate the growth morphology of ultra-thin Pb films on the Ni3Al(111) face at room temperature. A previous study [K. Miśków and A. Krupski Appl Surf Sci 273, 2013, 554] using low-energy electron diffraction (LEED) and real time Auger intensity recording has demonstrated that an initial two-dimensional growth of the first Pb monolayer thick ‘wetting layer’ takes place. With further deposition and for T = 300 K, flat three atomic-layer-high islands are grown. Above 350 K, the Stranski–Krastanov growth mode was observed. In the current study, the analysis of STM measurements indicate and confirm that for coverage θ = 1.0 ML two-dimensional growth of the first Pb monolayer took place. Above θ > 1.0 ML, a three-dimensional growth of the Pb islands was observed with a strongly preferred atomic-scale ‘magic height (N),’ hexagonal shape and flat-tops. At coverage θ = 3.5 ML, only islands containing N = 3, 5, 7 and 11 atomic layers of Pb are observed. At the higher coverage θ = 5.5 ML, three types of regular hexagonal islands with side lengths of 25, 30 and 45 nm are observed. Furthermore, three different island adsorption configurations rotated by 10° ± 1° and 30° ± 6° with respect to each other were observed. After an annealing at T = 400 K of 5.5 ML of lead deposited at RT on the Ni3Al(111) the morphology of the surface changes. Post-anneal, islands of Pb are observed above the ‘wetting layer’ with an estimated average size and diameter of 768 ± 291 nm2 and 38.17 ± 6.56 nm and constant uniform height of two atomic layers (N = 2)

Constraining the Equation of State with Moment of Inertia Measurements

We estimate that the moment of inertia of star A in the recently discovered double pulsar system PSR J0737-3039 may be determined after a few years of observation to something like 10% accuracy. This would enable accurate estimates of the radius of the star and the presure of matter in the vicinity of 1 to 2 times the nuclear saturation density, which would in turn provide strong constraints on the equation of state of neutron stars and the physics of their interiors.Comment: Submitted to ApJ, 4 figure

Time-resolved photoelectron imaging of model biological chromophores

Investigating the underlying forces that have a key role in light-matter interactions is crucial to understanding many fundamental processes that occur in nature. This thesis describes a series of experiments investigating model biological chromophores, providing an insight into the photochemistry of “ultraviolet selfprotection” schemes, invoked in many molecules involved in the protection of flora and fauna from the potentially damaging effects of excess ultraviolet radiation. These experiments are achieved through the application of time-resolved photoelectron imaging (TR-PEI) supported by high-level computational chemistry calculations. This thesis will set out both the motivation for the work, consisting of a comprehensive literature review of the subject, as well as an in-depth description of the optical set-up, laser system and spectrometer, as well as non-trivial data handling approaches involved in performing the experiments. This will lead on to work concerning the model chromophore aniline (and several aniline derived systems), guaiacol and finally a series of tertiary aliphatic amines. To conclude, various potential avenues of future work are discussed, considering both the experimental methodology and possible molecules of interest building upon the work described within this thesis
