We study supersymmetric [Formula omitted] black holes from matter-coupled F(4) gauged supergravity coupled to four vector multiplets with [Formula omitted] gauge group. This gauged supergravity admits a maximally supersymmetric [Formula omitted] vacuum with [Formula omitted] symmetry. We find a number of new supersymmetric [Formula omitted] solutions by performing topological twists along [Formula omitted]. For [Formula omitted] being a product of two Riemann surfaces [Formula omitted], we perform a twist by [Formula omitted] gauge fields and find [Formula omitted] solutions for at least one of the Riemann surface being negatively curved. For [Formula omitted] being a Kahler four-cycle [Formula omitted], a twist by [Formula omitted] gauge fields leads to [Formula omitted] solutions for negatively curved [Formula omitted]. Finally, performing a twist by turning on SO(3) gauge fields in the case of [Formula omitted] being a Cayley four-cycle [Formula omitted] also leads to [Formula omitted] solutions for negatively curved [Formula omitted]. We give numerical black hole solutions interpolating between all of these [Formula omitted] near horizon geometries and the asymptotically locally [Formula omitted] vacuum. It is also possible to uplift all of these solutions to type IIB theory via consistent truncations on [Formula omitted] leading to a new class of supersymmetric [Formula omitted] solutions.

There is a need for alternative treatments for postharvest pests on stored products. In this study, 45-d long-term controlled atmosphere (CA) treatments with 3, 5, 6.5, and 8% [O.sub.2] were studied to determine effects on survival and development of rice weevil (Sitophilus oryzae) and confused flour beetle (Tribolium confusum) eggs and susceptibility of different life stages to a 14-d 5% [O.sub.2] treatment. Low oxygen treatments were effective against S. oryzae and T. confusum. The 45-d CA treatments with 6.5, 5, and 3% [O.sub.2] resulted in 0.26, 0.004, and 0% survival rates from egg to adult respectively for S. oryzae and 6.51, 0.14, and 0% survival rates from egg to later stages respectively for T. confusum. For both species, eggs were more susceptible to low oxygen treatment than larvae or pupae. A 14-d CA treatment with 5% [O.sub.2] resulted in 4.9 and 3.3% survival of eggs of S. oryzae and T. confusum, respectively, as compared with over 50% survival of larvae and pupae for both species. S. oryzae adults, however, were very susceptible to low oxygen treatment and 14-d exposure to 5% [O.sub.2] atmosphere resulted in zero survival. In contrast, the 14-d exposure to 5% [O.sub.2] atmosphere resulted in over 94% survival for T. confusum adults. This study suggested there were considerable differences between stored product insects in susceptibility to low oxygen treatment and that long-term CA storage treatments with a low oxygen level of [less than or equal to]6.5 and [less than or equal to]5% have potential in controlling S. oryzae and T. confusum, respectively. Key words: controlled atmosphere, stored product pest control, rice weevil, confused flour beetle

Carbon capture and sequestration (CCS) is a promising technology for reducing CO[sub.2] emissions to the atmosphere. It is critical to estimate the CO[sub.2] storage resource before deploying the CCS projects. The CO[sub.2] storage resource is limited by both the formation pore volume available to store CO[sub.2] and the maximum allowable pressure buildup for safe injection. In this study, we present a workflow for estimating the volume- and pressure-limited storage efficiency factor and quantifying the uncertainty in the estimates. Thirteen independent uncertain physical parameters characterizing the storage formation are considered in the Monte Carlo uncertainty analysis. The uncertain inputs contributing most to the overall uncertainty in the storage efficiency factor are identified. The estimation and uncertainty quantification workflow is demonstrated using a publicly available dataset developed for a prospective CO[sub.2] storage site. The statistical distributions of the storage efficiency factor for the primary storage formation and the secondary storage formation located in deeper depth are derived using the proposed workflow. The effective-to-total porosity contributes most to the overall uncertainty in the estimated storage efficiency factor at the study site, followed by the maximum allowable pressure buildup, the net-to-gross thickness ratio, the irreducible water saturation, and the permeability. While the significant uncertain input variables identified are tailored to the characteristics of the study site, the statistical methodology proposed can be generalized and applied to other storage sites. The influential uncertain inputs identified from the workflow can provide guidance on future data collection needs for uncertainty reduction, improving the confidence in the CO[sub.2] saline storage resource estimates.

The diversity of species in Amazonia is exceptionally vast and unique, and it is of great interest for industry sectors to explore the potential of derivatives with functional properties for packaging applications. This study proposes the functionalization of cellulose micro/nanofibril (MFC/NFC) suspensions from Heteropsis flexuosa with andiroba oil to produce films with packaging potential. MFC/NFC was produced by using mechanical fibrillation from suspensions of H. flexuosa fibers. Proportions of 1, 3, and 5% of andiroba oil were added to make films with concentrations of 1% (m/m). Suspensions with andiroba oil provided greater viscosity, with changes in the physical properties of the films. Functionalization with andiroba oil provided films with lower degradation in water, greater contact angle, and lower wettability despite high permeability to water vapor. The films with 1% andiroba oil showed a hydrophobic characteristic (contact angle > 90°) and greater puncture resistance (6.70 N mm[sup.−1]). Films with 3% oil showed a more transparent appearance and high biodegradation, while 1% oil generated more opaque films with a higher thermal degradation temperature and high antioxidant activity. It was concluded that films produced from H. flexuosa fibers functionalized with andiroba oil showed packaging potential for light, low-moisture products due to their adequate thermal and barrier characteristics.

Direct lithium extraction (DLE) is emerging as a promising alternative to brine extraction although it requires further processing to obtain high-quality products suitable for various applications. This study focused on developing a process to concentrate and purify complex LiCl solutions obtained through direct lithium extraction (DLE). Two different chemical compositions of complex LiCl solutions were used, dividing the study into three stages. In the first part, lithium was concentrated to 1% by mass by evaporation. In the second, electrodialysis was used to alkalinize the LiCl solution and remove magnesium and calcium impurities under different current densities. The best results obtained were magnesium and calcium removals of 99.8% and 98.0%, respectively, and lithium recoveries of 99% and 96%. In the third stage, the selectivity of two different commercial cationic membranes (Nafion 117 and Neosepta CMS) was evaluated to separate Li[sup.+], K[sup.+], and Na[sup.+] cations under different current densities and volumetric flow rates. The Neosepta CMS membrane demonstrated higher lithium recovery. This study evaluated the quality of the purified lithium-rich solution and its potential use both in the production of Li[sub.2]CO[sub.3] as well as in the electrochemical production of LiOH.

In this paper finds semi-approximate solutions for nonlinear Integro-Differen-tial Equations of fractional order (FIDEs) of the Volterra-Fredholm-Hammerstein (VF-H) type, where the higher-order fractional derivative is defined in the Caputo sense, by effectively using the Adomian Decomposition Method and the Modified Adomian Decomposition Method as computational techniques. This method involves converting VF-H type FIDEs into iterative algebraic equations. In this approach, the answer to these equations is the product of an endless series of terms, which usually converges to the solution given by the noise terms. For numerical reasons, a reduced number of terms is utilised when a closed-form solution cannot be found. Lastly, these notions are illustrated using examples. Keywords: Volterra-Fredholm-Hammerstein, Caputo-fractional derivative, Adomian decomposition method, Modified Adomian decomposition method. AMS Subject Classification: 34A08, 26A33, 37C25.

\"Trading fours\" is a musical term for when two musicians improvise with each other in a call and response method. The first musician improvises for four bars/measures, while the second listens. The second then improvises using what he/she heard from the first musician, changes it, making his or her own improvised four measures. The process is then repeated. The goal of this project is to create a computer program that a musician can use to \"trade fours\" with, called \"Trading4s.java.\" First, it is hypothesized that pianists improvise in their own unique patterns, changing three variables-rhythm, pitches, and dynamics. Three subjects were prompted with two different backing tracks, one being a swung C 12-bar blues chord progression, and then a Bossa Nova style track. Each played an improvised solo over these tracks on a piano keyboard. The improvised solos were recorded via MIDI. The analysis of the solos included checking for patterns in rhythm, pitches, and dynamics. The data, collected from the improvised solos of each subject, show distinct patterns repeated in terms of rhythm and pitches, specific to each pianist. The data supports the original hypothesis. The Trading4s algorithm builds off the experiment's findings that there are patterns in the pitches and rhythm. Trading4s.java mimics \"trading fours\" by intaking a short MIDI file and creating a new MIDI file that either copies the rhythm from the input and randomly assigns pitches, or copies the pitches from the input and strategically assigns a rhythm, creating a new responding improvisation.

This study presents a comprehensive evaluation of a modified membrane cascade operating in “Continuous Membrane Column” mode for selective CO[sub.2] capture in combined heat power plants. For the first time, a novel membrane cascade configuration for separating four-component wet flue gases is analyzed and compared with existing technologies in terms of the capital and operating costs required to capture one ton of CO[sub.2]. The proposed membrane cascade generates two countercurrent recirculating streams: one continuously depleted of the permeate component and the other enriched in it. Because the internal recirculation streams significantly exceed the bypass product streams, the system demonstrates a multiplicative increase in separation efficiency. As a result, the required membrane area and compression energy can be significantly reduced. The analysis demonstrates that the proposed cascade configuration meets all current performance requirements for CO[sub.2] recovery and the target composition of the product and residual streams. Furthermore, due to its balanced material and energy cost ratio, the system can serve as a competitive alternative to previously developed membrane CO[sub.2] capture technologies, offering lower overall capture losses.
