description: The feasibility of employing the biological activated carbon (BAC) process to debilitate azo dye Carmoisine by Klebsiella spp. was investigated. Plate assay revealed the capability of Klebsiella spp. for removal of Carmoisine via degradation. Kinetic parameters were measured for Carmoisine debilitation by Klebsiella spp. using the suspended anaerobic process. Two types of granular and rod-shaped activated carbon were used to form the biological beds in order to study the Carmoisine debilitation in batch processes. Scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM) were used to indicate the colonization and biofilm formation of bacteria grown on activated carbon particles (ACPs). Thin layer chromatography (TLC), liquid chromatography-mass spectrometry (LC-MS), High pressure liquid chromatography (HPLC) and biosorption studies demonstrated biotransformation of Carmoisine into its constituent aromatic amines during the Carmosine debilitation in suspended anaerobic and BAC processes. The porosity of activated carbons, inoculation size and age of biological beds were the important factors affecting the viability of bacterial cells grown on ACPs and consequently rate and efficiency of the Carmoisine debilitation process determined through spectrophotometry. Reusability of biological beds was demonstrated by conducting sequential batch experiments. In conclusion, the BAC process proved to be an efficient method for anaerobic dye degradation.

description: Developing high-performance adsorbent for hexavalent chromium (Cr(VI)) elimination presents an enticing prospect in environmental remediation. Herein, three-dimensional flowerlike nanospheres composed of molybdenum disulphide and polypyrrole (MoS2@PPy) were successfully prepared via a one-pot hydrothermal and subsequent carbothermal reduction process for the removal of Cr(VI). The effects of pH, adsorbent dosage, co-existing ions, initial Cr(VI) concentration and temperature were investigated systematically by batch experiments. Benefiting from the incorporation of MoS2, the obtained MoS2@PPy composites showed a dramatic increase of specific surface area (149.82 m2·g−1) and adsorption capacity (230.97 mg·g−1) when compared with the pure PPy nanoparticles. Based on the thermodynamics study and X-ray photoelectron spectroscopy analyses, the removal process of Cr(VI) was proved to be exothermic and spontaneous, and accessible under-coordinated Mo(IV) and pyrrolic N groups coupled with redox reactions were conducive to the efficient removal of Cr(VI). Attractively, the MoS2@PPy acted as the electron donor could also activate peroxymonosulphate for the efficient degradation of organic contaminants. These results suggested that the MoS2@PPy was promising in Cr(VI) elimination and other kinds of organic pollutants removal in wastewater.
Energy-Efficient Wearable Activity Recognition through Activity-Aware Sensor Data Compression and Exploring the Usage of Ultrawide-band Radars for HAR

description: Human activity recognition (HAR) using low-power wearable devices provides an attractive solution for several applications, including remote health monitoring, rehabilitation, and activity promotion. Recent approaches for HAR collect data from multiple sensors mounted on the body to improve the accuracy or the number of activities being recognized. Multiple sensors necessitate communication between the sensors and the processing nodes, leading to high energy consumption. However, transmitting raw sensor data over wireless communication technologies such as WiFi or BLE may not be feasible on energy-constrained wearable devices. This work proposes a novel activity-aware sensor data compression and approximation approach for neural-network-based HAR classifiers. Our approach is based on two key insights: 1) most daily human activities do not have high data variations, thus allowing high compression ratios, and 2) neural network classifiers inherently include some redundancy and can be trained to handle approximations in sensor data. Our experiments
description: on three datasets show that the proposed approach achieves an average compression ratio of 14 times with as much as 85–95% communication energy savings over a day for a typical pattern of human activities compared to no compression scenario. Moreover, we perform the exploratory study on using Ultra-Wideband (UWB) for HAR problems, show the technical possibilities and limitations, discuss previous works targeting healthcare-related applications, and perform preliminary experiments to show the usage of UWB for HAR.

description: Einstenian cubic gravity (ECG) is a modified theory of gravity constructed with cubic contractions of the curvature tensor. This theory has the remarkable feature of having the same two propagating degrees of freedom of Einstein gravity (EG), at the perturbative level on maximally symmetric spacetimes. The additional unstable modes steaming from the higher order derivative dynamics are suppressed provided that we consider the ECG as an effective field theory wherein the cubic terms are seen as perturbative corrections of the Einstein-Hilbert term. Extensions of ECG have been proposed in cosmology and compact objects in order to probe if this property holds in more general configurations. In this work, we construct a modified ECG gravity in a five dimensional warped braneworld scenario. By assuming a specific combination of the cubic parameters, we obtained modified gravity equations of motion with terms up to second-order. For a thin 3-brane, the cubic-gravity corrections yield an effective positive bulk cosmological constant. Thus, in order to keep the 5D bulk warped compact, an upper bound of the cubic parameter with respect to the bulk curvature was imposed. For a thick brane, the cubic-gravity terms modify the scalar field potential and its corresponding vacuum. Nonetheless, the domain-wall structure with a localized source is preserved. At the perturbative level, the Kaluza-Klein (KK) tensor gravitational modes are stable and possess a localized massless mode provided the cubic corrections are small compared to the EG braneworld.

description: We investigate the viability of primordial black hole (PBH) formation in the Standard Model (SM) in a scenario that does not rely on specific inflationary features or any exotic physics such as phase transitions or non-minimal coupling to gravity. If the Brout-Englert-Higgs (BEH) field lies exactly at the transition between metastability and stability, its potential exhibits an inflexion point due to radiative corrections. The BEH can act like a stochastic curvaton field, leading to a non-Gaussian tail of large curvature fluctuations that later collapse into PBHs when they re-enter inside the horizon. This scenario would require a precise value of the top-quark mas to ensure the Higgs stability, which is disfavored but still consistent with the most recent measurements. However, we also find that large curvature fluctuations are also generated on cosmological scales that are inconsistent with cosmic microwave background (CMB) observations. We therefore conclude that the SM cannot have led to the formation of PBHs based on this mechanism. Nevertheless, a variation of the scenario based on the Palatini formulation of gravity may have provided the conditions to produce stellar-mass PBHs with an abundance comparable to dark matter, without producing too large curvature fluctuations on cosmological scales.

description: This study focuses on feminists in Dallas and Houston in the 1970s who organized strategically at a grassroots level. These Texas women organized around issues including the Equal Rights Amendment (the ERA), abortion, rape, and violence against women. Texas is a critical site for understanding the political and social organization of women in the 1970s, both at the local level and as part of larger, national efforts. This study draws primarily from feminist newsletters and periodicals from Dallas and Houston including Women for Change, Equal Times, Woman, Broadside and Breakthrough. Further, the study utilizes archival material from the Texas Federation of Business and Professional Women records.This thesis demonstrates the ways that feminists used print at a local level to organize and advocate for issues that were important in their cities, as well as to engage with a larger national feminist network. Further, it engages with the pushback that feminists faced because of their position on these issues. When it came to the ERA, conservative women like the Women Who Want to be Women (WWWW) formed in response and worked to rescind the amendment. They also conflated the passage of the ERA with the legalization of abortion. Feminists in Texas used their periodicals and organizations to formulate how to best protect abortion, and how to deal with anti-ERA and anti-abortion sentiments. Lastly, the Dallas and Texas feminists used their periodicals and organizations to combat rape and violence in their cities. They worked to dispel myths about violence against women as well as to create practical solutions to support women.
description: This work adds to the broader field of women and gender studies and twentieth-century political movements. It also adds to the literature about feminism in the American South as well as literature about growing religious Right that came to fruition by the 1980s. By concentrating on local organizations and periodicals, this thesis reveals what was important to everyday Texas women and how they used their organizations to be politically active. Further, it demonstrates the efforts of Texas feminists to make their communities, state, and nation a more equitable and safer place.

description: Objectives: To evaluate incidences of pyometra and orthopedic, behavioral, urinary/reproductive, neoplastic, or atopic disease processes as outcomes for dogs undergoing either a laparoscopic-assisted ovarian-sparing spay/hysterectomy (LapOSS) or a laparoscopic ovariectomy (LapOVE). Animals: Thirty-three client-owned dogs.
description: Procedures: Medical records of client-owned dogs presenting between August 2013 and May 2020 for elective LapOSS or LapOVE were reviewed. A multiple-choice client questionnaire was emailed to all clients whose dogs’ complete medical records were available.
description: Results: Seventeen of the 33 dogs were in the LapOSS group, and sixteen of 33 dogs were in the LapOVE group. Of the 17 dogs undergoing LapOSS, 5/17 (29%) underwent an elective ovariectomy (OVE) at a later date. The mean follow-up time was 4.2 (± 1.8) years for the LapOSS group and 4.3 (± 2.0) years for the LapOVE group. No dogs developed stump pyometra. One LapOSS dog developed mammary tumor and two others developed non-reproductive malignant neoplasia, while two of the LapOVE dogs developed malignant neoplasia. One of the LapOSS dogs with malignant neoplasia had an ovariectomy prior to development of disease.
description: Clinical Relevance: Laparoscopic-assisted ovary-sparing spay appears to provide a safe and reliable method of sterilization, with no observable increased risk of pyometra with hysterectomy. Owners must be counseled prior to surgery regarding the consequences of gonadal hormone retention and multiple heat cycles.

description: Ash transport and deposition from volcanic eruptions can pose significant hazards to human health and infrastructure. Particle size plays an important role in modeling efforts to predict ash fall because large particles fall faster than small particles and deposit closer to the vent exit. Aggregation, or the formation of individual particles into clusters, can greatly impact ash particle size. This study investigates the influence of humidity and Stokes number on aggregation within a particle-laden jet flow. These factors have been previously shown to be relevant to aggregation in prior studies, but have not been studied extensively within jet flow. To address this, a vertical air jet was seeded with hollow glass and nickel particles at typical mass loadings of ϕ =1.1±0.5%. Aggregates were examined over a range of Reynolds numbers (Re=5500-11000), Stokes numbers (St=1.0-9.4), and relative humidities (RH=40-75%). The median size of collected nickel particles at St = 9.4 and RH = 75% increased by 50% from lower humidity trials at RH = 40 - 60%, while the hollow glass particles at St = 1.0 did not show sensitivity to humidity from RH = 40-75%.
description: Separately, submarine volcanic eruptions can exhibit vastly different behavior than sub-aerial eruptions. The entrainment of water into these submerged gas jets is a critical factor in predicting their behavior. A preliminary analysis of entrainment for an air jet submerged in water is conducted, over a range of Reynolds numbers (Re=500-1500) and nozzle diameters (d = 1/8-1/4”). On average, increasing the Reynolds number by 75% decreased the mass entrainment coefficient (Ce) 30% over these flow conditions. Doubling the nozzle diameter from 1/8” to 1/4” and holding the Reynolds number constant yielded a decrease of ∼17% in Ce. The limitations of the current apparatus are discussed, and suggestions for future experimental designs are given.

description: FAMILY URANORHAGIONIDAE ZHANG, YANG & REN FAM. NOV.
Type genus: Uranorhagio gen. nov.
Diagnosis: Body stout. Head round. Mesonotum slightly convex. Hind tibia with spur(s), empodia pulvilliform. Wing slender relative to body. Veins thick and strong. Vein Sc ending slightly beyond the middle of the wing; veins R 1 and Rs 1 long, vein R 2+3 distinctly and strongly bent upwards at base, vein R 5 ending at (or beyond) wing apex; veins M 1 and M 2 bifurcating, distal of crossvein m–m; cell sc wide open; cell r 4 slender; five posterior cells present and wide open, cell cup distinctly open; anal lobe small and narrow, alula unconspicuous.
Stratigraphic and geographic range: The Middle Jurassic, China.
Remarks: Uranorhagionidae fam. nov. is considered to be a member of the lower Orthorrhapha, because of the stout body, the presence of tibia spur(s), and pulvilliform empodia. Contrasting with other families of lower Orthorrhapha, this new family is somewhat similar to the Rhagionidae family. However, we cannot put these specimens in any known families, because of their special and unique wing venation. Therefore, we erect a new family in superfamily Tabanoidea for them. We can differentiate Uranorhagionidae fam. nov. from Rhagionidae by the following characters: veins Sc and R 1 long; vein R 2+3 fornical at base; vein CuA 2 short; cell d extending to near the wing margin (in Uranorhagio gen. nov.); hind femur swollen at apex; and nine abdominal segments. Also, this family is superficially similar to the Rhagionemestriidae family (especially for Iberomosca). But, we can easily separate the new family from Iberomosca by the following features: vein Rs 1 extends much longer than vein Rs 2; vein R 2+3 is fornical at the base; cell br is longer than cell bm; the cell cup is open at the wing margin; and there is no distinct diagonal vein.

description: In 2020, hydrogen chloride (HCl) in the gas phase was discovered in the atmosphere of Mars with the Atmospheric Chemistry Suite (ACS) onboard the Trace Gas Orbiter (TGO) mission (Korablev et al., 2021). Its volume mixing ratio (VMR) shows a seasonal increase of up to 5 ppbv during the perihelion season, followed by a sudden drop to undetectable levels, contradicting previous estimations of the HCl lifetime of several months. In the Earth's stratosphere, heterogeneous uptake of HCl onto water ice is known to be a major sink for this species. Modelling of associated chemistry involving heterogeneous reactions indicates that H2O ice becomes the most effective sink for HCl above 20 km with the characteristic time shorter than 12 hours. In this work, we use simultaneous measurements of water ice particles and HCl abundance obtained by the ACS instrument and show particular structures in the vertical profiles, forming detached layers of gas at the ice free altitudes ('ice-holes'). We demonstrate that the heterogeneous uptake of HCl onto water ice operates on Mars and is potentially a major mechanism regulating the HCl abundance in the atmosphere of Mars.
