Impact of protein source and ammonium chloride inclusion on Boer goat growth and carcass quality
Get PDFResearch of feedlot goats has gained importance as goat consumption in the United States has increased tremendously in within recent years. In the field of goat nutrition, there is minimal research regarding reference diets and no peer reviewed studies with dried distillers’ grains with soluble (DDGS). The objective of this project was evaluating the effect of SoyPlus as a protein supplement in a diet for feedlot goats and substituting ammonium chloride with SoyChlor in high rumen undigestible protein (RUP) feedlot Boer goat diets. Seventy-five Boer-influenced goats were allocated to 5 treatments in a random titration design. Goats were stratified by BW into 25 pens (5 pens/treatment; 3 goats/pen) for a 42-day finishing study. All diets were isonitrogenous and isocaloric, formulated to meet equal daily requirements and equal chloride value. The dietary treatments being evaluated were 1) Soybean meal (SBM) with Ammonium chloride (AmCl), 2) DDGS with AmCl, 3) SoyPlus with AmCl, 4) SBM with SoyChlor, and 5) SoyPlus with SoyChlor. Goats remained on self-feeders with continuous access to their respective pellets and clean, fresh water. Throughout the trial body weight (BW), average daily gain (ADG), average daily feed intake (ADFI), and gain to feed (G:F) were measured and calculated every 7 days. Beginning BW were similar across treatments (P=0.57). The inclusion of SoyPlus and SoyChlor had no effect (P>0.14) on BW or ADFI from day 0 to day 42. Feed Cost 7.07 (P=0.02). Ultimately, these results confirm that the inclusion of SoyPlus and SoyChlor have no effect on the growth rate of feedlot boar goats. Feeding these diets will mean greater production cost, resulting in the same amount of muscle growth. At these prices, DDGS are the best option when formulating diets and keeping the cost minimal
The Amazing Aggregation Skills of the Red Flour Beetle
Get PDFThe Red Flour Beetle is a major pest of grain processing plants. They are commonly found in temperate areas, such as the southern parts of the United States. The beetles are usually reddish brown, with adults ranging about 1/8 of an inch in size. It's very common to find large numbers of Red Flour Beetles clumped together within infested grain (Baldwin and Fasulo, 2003). This dense clumping has caused speculation on whether this strange aggregation behavior is due to environmental factors or related to shared genetic traits. Scientists can look at the influence of genes on behavior by using a mathematical formula called a heritability estimate. Heritability estimates give information about how much of an impact genes have on a behavior in a certain environment (Khan Academy, 2018). Instinctive behavior is also connected to the genetic information, when best determines behavior when a species' environment varies little from generation to generation (Breed and Sanchez, 2010). This instinctive behavior theory correlated with the hypotheses, if you place Red Flour beetles with different genetic strains into an environment together then the Red Flour Beetles with similar genetic strains will aggregate together. While conducted the research which included placing different Beetles with different genetic strains into the same environment, and recording the data, the result supported the hypothesis and helped further prove the instinctive behavior that organisms possess when it comes to their genetic information. When using the graphs theory to analyze the data, the results showed that in the first day of observation, the largest percentage of interactions per group was for neither the genetic traits nor the environmental traits. However, when observing the second day the largest percentage of interactions per group was the genetic traits, helping to support the question of the different effects genetic and environmental traits have on the aggregation of Red Flour Beetles. The results seem to support the fact that genetic information is a major key in helping to create interactions between organisms of the same genetic strain, as well as bringing these interactions back to equilibrium when the population is shuffled. These finding are huge for the Animal Sciences and Industry field, by helping to prove that instincts and behavior coexist and are more significant than just an environmental change, when it comes to organisms. This research also helps to pinpoint different aggregation habits

Time-resolved inner-shell photoelectron spectroscopy: From a bound molecule to an isolated atom
Get PDFDue to its element and site specificity, inner-shell photoelectron spectroscopy is a widely used technique to probe the chemical structure of matter. Here, we show that time-resolved inner-shell photoelectron spectroscopy can be employed to observe ultrafast chemical reactions and the electronic response to the nuclear motion with high sensitivity. The ultraviolet dissociation of iodomethane (CH3I) is investigated by ionization above the iodine 4d edge, using time-resolved inner-shell photoelectron and photoion spectroscopy. The dynamics observed in the photoelectron spectra appear earlier and are faster than those seen in the iodine fragments. The experimental results are interpreted using crystal-field and spin-orbit configuration interaction calculations, and demonstrate that time-resolved inner-shell photoelectron spectroscopy is a powerful tool to directly track ultrafast structural and electronic transformations in gas-phase molecules

Dissolved fulvic acids from a high arsenic aquifer shuttle electrons to enhance microbial iron reduction
Get PDFCitation: Harshad V. Kulkarni, Natalie Mladenov, Diane M. McKnight, Yan Zheng, Matthew F. Kirk, Diana R. Nemergut, Dissolved fulvic acids from a high arsenic aquifer shuttle electrons to enhance microbial iron reduction, In Science of The Total Environment, 615, 1390-1395, https://doi.org/10.1016/j.scitotenv.2017.09.164It was demonstrated more than two decades ago that microorganisms use humic substances, including fulvic acid (FA), as electron shuttles during iron (Fe) reduction in anaerobic soils and sediments. The relevance of this mechanism for the acceleration of Fe(III) reduction in arsenic-laden groundwater environments is gaining wider attention. Here we provide new evidence that dissolved FAs isolated from sediment-influenced surface water and groundwater in the Bengal Basin were capable of electron shuttling between Geobacter metallireducens and Fe(III). Moreover, all four Bangladesh sediment-derived dissolved FAs investigated in this study had higher electron accepting capacity (176 to 245 μmol/g) compared to aquatic FAs, such as Suwanee River Fulvic Acid (67 μmol/g). Our direct evidence that Bangladesh FAs are capable of intermediate electron transfer to Fe(III) supports other studies that implicate electron shuttling by sediment-derived aqueous humics to enhance Fe reduction and, in turn, As mobility. Overall, the finding of greater electron accepting capacity by dissolved FAs from groundwater and other sediment-influenced environments advances our understanding of mechanisms that control Fe reduction under conditions where electron transfer is the rate limiting step

Ratios of double to single ionization of He and Ne by strong 400-nm laser pulses using the quantitative rescattering theory
Get PDFCitation: Chen, Z., Li, X., Zatsarinny, O., Bartschat, K., & Lin, C. D. (2018). Ratios of double to single ionization of He and Ne by strong 400-nm laser pulses using the quantitative rescattering theory. Physical Review A, 97(1). https://doi.org/10.1103/PhysRevA.97.013425We present numerical simulations of the ratio between double and single ionization of He and Ne by intense laser pulses at wavelengths of 390 and 400 nm, respectively. The yields of doubly charged ions due to nonsequential double ionization (NSDI) are obtained by employing the quantitative rescattering (QRS) model. In this model, the NSDI ionization probability is expressed as a product of the returning electron wave packet (RWP) and the total scattering cross sections for laser-free electron impact excitation and electron impact ionization of the parent ion. According to the QRS theory, the same RWP is also responsible for the emission of high-energy above-threshold ionization photoelectrons. To obtain absolute double-ionization yields, the RWP is generated by solving the time-dependent Schrödinger equation (TDSE) within a one-electron model. The same TDSE results can also be taken to obtain single-ionization yields. By using the TDSE results to calibrate single ionization and the RWP obtained from the strong-field approximation, we further simplify the calculation such that the nonuniform laser intensity distribution in the focused laser beam can be accounted for. In addition, laser-free electron impact excitation and ionization cross sections are calculated using the state-of-the-art many-electron R-matrix theory. The simulation results for double-to-single-ionization ratios are found to compare well with experimental data and support the validity of the nonsequential double-ionization mechanism for the covered intensity region

Real-Time Observation of Molecular Spinning with Angular High-Harmonic Spectroscopy
Get PDFCitation: He, L., Lan, P., Le, A.-T., Wang, B., Wang, B., Zhu, X., … Lin, C. D. (2018). Real-Time Observation of Molecular Spinning with Angular High-Harmonic Spectroscopy. Physical Review Letters, 121(16), 163201. https://doi.org/10.1103/PhysRevLett.121.163201We demonstrate an angular high-harmonic spectroscopy method to probe the spinning dynamics of a molecular rotation wave packet in real time. With the excitation of two time-delayed, polarization-skewed pump pulses, the molecular ensemble is impulsively kicked to rotate unidirectionally, which is subsequently irradiated by another delayed probe pulse for high-order harmonic generation (HHG). The spatiotemporal evolution of the molecular rotation wave packet is visualized from the time-dependent angular distributions of the HHG yields and frequency shift measured at various polarization directions and time delays of the probe pulse. The observed frequency shift in HHG is demonstrated to arise from the nonadiabatic effect induced by molecular spinning. Different from the previous spectroscopic and Coulomb explosion imaging techniques, the angular high-harmonic spectroscopy method can reveal additionally the electronic structure and multiple orbitals of the sampled molecule. All the experimental findings are well reproduced by numerical simulations. Further extension of this method would provide a powerful tool for probing complex polyatomic molecules with HHG spectroscopy
