Heritage Greens Consumption: A Qualitative Exploration of Cultural Agency in the Southern Arizona Food System

Throughout history, wild green vegetables have played a significant role in human diets around the world, coevolving alongside agriculture and changing land use patterns (Wilson, 1990). Wild greens such as purslane (Portulaca oleracea), lambquarters (Chenopodium spp.) and amaranth (Amaranthus spp.), wild ancestors of crop plants, are prehistoric foods that are cultural and nutritional mainstays in many parts of the world including the Arizona-Mexico borderland region. While consumption of these foods is commonplace on the Mexican side of the border, on the American side their use is less frequent. In this study, I explore the patterns of and barriers to consumption of wild green vegetables by Latinos living in the Arizona (AZ)-Mexico (MX) borderland city of Tucson, AZ. I use Weber’s rationalization theory, as well as human agency theory, to guide my exploration of how the dominant food system contributes to dietary acculturation and the loss of agency among Latinos living in Tucson. In-depth interviews and naturalistic observations are employed across a diverse array of market settings, which include a farmers’ market, several carnicerías (Mexican butcher shops), a corner store/tortilleria with procurers and purveyors of Latino and indigenous foods, and a more conventional supermarket. The findings reveal a reduction in knowledge and consumption of heritage greens by Latinos concurrent to their adoption of more mainstream American foods. I consider this pattern and its various implications in the context of the rationalization of the dominant U.S. food system, which leads to a dynamic that favors efficiency and productivity over authenticity and aesthetics.
The Role of Ocean Heat Transport in the Global Climate Response to Projected Arctic Sea Ice Loss

AbstractThe purpose of this study is to elucidate the individual and combined roles of thermodynamic and dynamic ocean–atmosphere coupling in the equilibrium global climate response to projected Arctic sea ice loss using a suite of experiments conducted with Community Climate System Model, version 4, at 1° latitude–longitude spatial resolution. The results highlight the contrasting spatial structures and partially compensating effects of thermodynamic and dynamic coupling. In combination, thermodynamic and dynamic coupling produce a response pattern that is largely symmetric about the equator, whereas thermodynamic coupling alone yields an antisymmetric response. The latter is characterized by an interhemispheric sea surface temperature (SST) gradient, with maximum warming at high northern latitudes decreasing toward the equator, which displaces the intertropical convergence zone (ITCZ) and Hadley circulation northward. In contrast, the fully coupled response shows enhanced warming at high latitudes of bo.
Interfacing Arduino Boards with Optical Sensor Arrays: Overview and Realization of an Accurate Solar Compass

In this paper, an overview of the potentiality of Arduino boards is presented, together with a description of the Arduino interfacing with light multi-sensors. These sensors can be arranged in linear arrays or in a matrix configuration (CCD or CMOS type cameras) and are equipped with tens, hundreds, or even thousands of elements whose sizes range from a few microns to tens of microns. The use of these sensors requires electronics that have high time accuracy, since they work through regular pulses sent by an external source and, furthermore, have the ability to digitize and store voltage signals precisely and quickly. We show that, with the appropriate settings, a simple Arduino board can handle both 1D and 2D optical sensors. Finally, we describe a solar compass made with such a board coupled to one of the tested optical array sensors that is capable of providing the north direction with a very high degree of accuracy.
Intrahospital Transport of Critically Ill Patients with Subarachnoid Hemorrhage—Frequency, Timing, Complications, and Clinical Consequences

Background: Patients with subarachnoid hemorrhage (SAH) often necessitate intra-hospital transport (IHT) during intensive care treatment. These transfers to facilities outside of the neurointensive care unit (NICU) pose challenges due to the inherent instability of the hemodynamic, respiratory, and neurological parameters that are typical in these patients. Methods: In this retrospective, single-center cohort study, a total of 108 IHTs were analyzed for demographics, transport rationale, clinical outcomes, and pre/post-IHT monitoring parameters. After establishing clinical thresholds, the frequency of complications was calculated, and predictors of thresholds violations were determined. Results: The mean age was 55.7 (+/−15.3) years, with 68.0% showing severe SAH (World Federation of Neurosurgical Societies Scale 5). IHTs with an emergency indication made up 30.8% of all transports. Direct therapeutic consequences from IHT were observed in 38.5%. On average, the first IHT occurred 1.5 (+/−2.0) days post-admission and patients were transported 4.3 (+/−1.8) times during their stay in the NICU. Significant parameter changes from pre- to post-IHT included mean arterial pressure, systolic blood pressure, oxygen saturation, blood glucose levels, temperature, dosages of propofol and ketamine, tidal volume, inspired oxygen concentration, Horovitz index, glucose, pH, intracranial pressure, and cerebral perfusion pressure. Relevant hemodynamic thresholds were violated in 31.5% of cases, while respiratory complications occurred in 63.9%, and neurological complications in 20.4%. For hemodynamic complications, a low heart rate with a threshold of 61/min (OR 0.96, 95% CI 0.93–0.99, p = 0.0165) and low doses of midazolam with a threshold of 17.5 mg/h (OR 0.97, 95% CI 0.95–1.00, p = 0.0232) significantly predicted adverse events. However, the model did not identify significant predictors for respiratory and neurological outcomes. Conclusions: Conclusively, IHTs in SAH patients are associated with relevant changes in hemodynamic, respiratory, and neurological monitoring parameters, with direct therapeutic consequences in 4/10 IHTs. These findings underscore the importance of further studies on the clinical impact of IHTs.
Patterns of Leaf Litter Decomposition as Related to Litter Traits in the Sudano-Guinea Savannahs of Ngaoundere, Cameroon

Litter decomposition processes are poorly studied in the savannahs. Leaf litter decomposition of the twenty-four contrasting plant species including trees, shrubs and grass species, was studied in the sudano-guinea savannahs of Ngaoundere, Cameroon. The litterbag technique was used to assess litter mass loss and single exponential model was adopted to estimate decay rate constants. Initial litter thickness varied from 0.02 to 1.11 mm, area from 4.27 to 245.89 mm2, sclerophyllous index from 0.01 to 1.75 mg.mm-2, density from 0.21 to 87.50 mg.mm-3, and speciﬁc mass area from 0.57 to 185.46 mm2.mg-1. Litter cellulose content varied from 3.79 to 11.84%; lignin from 2.84 to 8.12%, NDF from 21.35 to 80.41%, and total phenolic compounds from 0.47 to 17.76%. During the 52 weeks of the field experiment, mean dry mass remaining of litter samples was significantly between 8.05 and 75.22% of initial litter dry mass for C. papaya and C. regidus respectively. Litter decomposition rate constant (k) significantly ranged from 0.003 (C. regidus) to 0.121 %. week-1 (C. papaya). Litter mass remaining (LMR) was positively related to thickness (R2 = 0.605, P<0.01), Sclerophyllous index (R2 = 0.446, P<0.05), Specific mass area (R2 = 0.569, P<0.001), lignin (R2 = 0.631, P<0.01) and phenolic compounds (R2 = 0.618, P<0.001). The litter decomposition rate constant (k) was negatively related to thickness (R2 = 0.602, P<0.01, n=12), Sclerophyllous index (0.542; P<0.05), Specific mass area (0.419; P<0.05) and phenolic compounds (0.530; P<0.01). It can be concluded that litter decomposition is affected by plant species diversity, plant groups and physico-chemical traits of litters in the sudano-guinea savannahs of Ngaoundere, Cameroun. These preliminary results would contribute to understanding the mechanism of litter decomposition in general and in these savannahs in particular.
In Silico Drug Repurposing Studies for the Discovery of Novel Salicyl-AMP Ligase (MbtA)Inhibitors

Tuberculosis (TB) continues to pose a global health challenge, exacerbated by the rise of drug-resistant strains. The development of new TB therapies is an arduous and time-consuming process. To expedite the discovery of effective treatments, computational structure-based drug repurposing has emerged as a promising strategy. From this perspective, conditionally essential targets present a valuable opportunity, and the mycobactin biosynthesis pathway stands out as a prime example highlighting the intricate response of Mycobacterium tuberculosis (Mtb) to changes in iron availability. This study focuses on the repurposing and revival of FDA-approved drugs (library) as potential inhibitors of MbtA, a crucial enzyme in mycobactin biosynthesis in Mtb conserved among all species of mycobacteria. The literature suggests this pathway to be associated with drug efflux pumps, which potentially contribute to drug resistance. This makes it a potential target for antitubercular drug discovery. Herein, we utilized cheminformatics and structure-based drug repurposing approaches, viz., molecular docking, dynamics, and PCA analysis, to decode the intermolecular interactions and binding affinity of the FDA-reported molecules against MbtA. Virtual screening revealed ten molecules with significant binding affinities and interactions with MbtA. These drugs, originally designed for different therapeutic indications (four antiviral, three anticancer, one CYP450 inhibitor, one ACE inhibitor, and one leukotriene antagonist), were repurposed as potential MbtA inhibitors. Furthermore, our study explores the binding modes and interactions between these drugs and MbtA, shedding light on the structural basis of their inhibitory potential. Principal component analysis highlighted significant motions in MbtA-bound ligands, emphasizing the stability of the top protein–ligand complexes (PLCs). This computational approach provides a swift and cost-effective method for identifying new MbtA inhibitors, which can subsequently undergo validation through experimental assays. This streamlined process is facilitated by the fact that these compounds are already FDA-approved and have established safety and efficacy profiles. This study has the potential to lay the groundwork for addressing the urgent global health challenge at hand, specifically in the context of combating antimicrobial resistance (AMR) and tuberculosis (TB).

Hydrodynamic Characteristics of the Lombok Strait During the 2022 West Monsoon Peak and Estimation of Ocean Current Power Generation Potential

The Lombok Strait is one of the crucial straits in the Indonesian area because it falls in the Indonesian Archipelagic Sea Lanes of Communication II (ALKI II), and is considered as a strategic chokepoint. Additionally, it serves as a passage for ARLINDO, facilitating the movement of water masses from the Pacific to the Indian Ocean. This unique attribute creates a diverse ecosystem in the Lombok Strait due to the convergence of marine organisms from both oceans. The Lombok Strait presents an opportunity for harnessing renewable energy from its currents. However, there is a scarcity of direct measurements and oceanographic data for the Lombok Strait, making it impractical and costly to conduct direct observations using oceanographic mooring instruments. Therefore, one approach to better understand natural phenomena in the ocean is to use numerical methods such as Computational Fluid Dynamics (CFD) with the Finite Element Method (FEM) application. In this study, the software Mike3FM was used, which incorporates both Computational Fluid Dynamics (CFD) and the Finite Element Method (FEM). This software used bathymetric data and coastlines to create a triangular mesh in the horizontal plane and a grid mesh in the vertical plane. The simulations conducted in January 2022, for 30 days with hourly intervals around the sill area showed an average current velocity of 1.2 m/s at various depths, including 5, 50, 150, and 250 meters. The current primarily flowed southward in the direction of the Indian Ocean. The conversion of avarage current velocity to electrical power at depths of 5, 50, 150, and 250 meters above the sill yielded values of 0.86 kW, 0.70 kW, 0.34 kW, and 0.19 kW, respectively. Based on the results of the hydrodynamic modeling experiments, it is evident that the Lombok Strait has the potential to develop ocean current power generation.Keywords: Hydrodynamics, the Lombok Strait, CFD, FEM, West Monsoon.
Influência do número de rebentos na produção de mudas de bananeira

O experimento foi instalado na fazenda estância bacana no município de Itapirapuã – Goiás, o solo é classificado como Latossolo roxo, com uma topografia relativamente plana e bem drenada, foi utilizado o delineamento em blocos casualizados no esquema fatorial 3x2x4, em que foram testados três tipos de rebentos (chifrinho, chifre e chifrão), dois tipos de adubação (orgânica e química) em quatro blocos. Para a adubação orgânica foi utilizando 5 litros de esterco de curral misturado à terra da cova previamente aberta e para a adubação mineral foi utilizado 125g de sulfato de amônia (20% de Nitrogênio) e 83g de superfosfato simples (18% de P2O5) por cova. Para o controle de nematoides, foi aplicado a lanço o Carbofuran, na dose de 50g ao redor da touceira, sendo duas aplicações anual, a primeira em fevereiro de 2023 e a segunda em setembro do mesmo ano. Foram realizadas 7 pulverizações anuais contra o mal de sigatoca (Mycosphaerella musicola Leach), a cada 30 dias, com exceção dos meses de maio a setembro, quando as baixas temperaturas inibem o microrganismo, foram utilizadas neste ensaio 96 mudas da variedade nanica, sendo que cada parcela foi composta de 4 touceiras, espaçadas de 2,0 m nas linhas e 2,5 m nas colunas. Como o valor da estatística F (0,18321) para tratamentos é menor que o valor critico no nível de 5% de probabilidade (2,77), ele é não significativo nesse nível (P > 0,05), com isso não se pode rejeitar a hipótese de nulidade e concluímos que os tratamentos avaliados possuem efeito semelhantes, assim como o valor da estatística F (0,26718) para blocos é menor que o valor critico no nível de 5% de probabilidade (3,16), ele é não significativo nesse nível (P > 0,05), com isso aceita-se a hipótese nula e conclui-se que o fator controlado por blocos não influi na produção de mudas, para a interação (tipo de muda e adubação), o valor da estatística F (1,5733) é menor que o valor critico no nível de 5% de probabilidade (3,55), ele é não significativo nesse nível (P > 0,05), logo, não podemos rejeitar a hipótese nula e concluímos que a produção de mudas independe da adubação.
Multisite Is Superior to Single-Site Intratumoral Chemotherapy to Retard the Outcomes of Pancreatic Ductal Adenocarcinoma in a Murine Model

Simple Summary The intrinsic architecture of pancreatic cancer is limiting the efficient dispersion of systemically administered drugs. The research in a mouse model presented herein aims to demonstrate that a multifocal intratumoral drug injection for wider dispersion combined with systemic therapy offers a significant clinical advantage compared to a similar treatment at the same local dosage at a single focus. The encouraging findings obtained may be translated into clinical practice to enhance the quality of life and life expectancy of pancreatic cancer patients. Abstract Introduction: Locally advanced unresectable pancreatic cancer (LAPC) has a dismal prognosis, with intratumoral therapies showing limited benefits. We assume that the dense stroma within these tumors hampers drug dispersion. Aim: This study explores the efficacy of multisite intratumoral injections in improving a drug’s distribution while minimizing its side effects. Methods and Results: In mice with orthotopic LAPC tumors, weekly intratumoral injections of oxaliplatin at four separate sites reduced the tumor growth by 46% compared with saline (p < 0.003). Oxaliplatin exhibited the greatest impact on the tumor microenvironment relative to gemcitabine, Abraxane, or their combination, with increased necrosis, apoptosis, fibroblasts, inflammation, and infiltrating lymphocytes (p < 0.008). When combined with intravenous FOLFIRINOX (FFX), multisite intratumoral oxaliplatin reduced the tumor weight by 35% compared with single-site injection (p = 0.007). No additional visible toxicity was observed even at a 10-fold occurrence of intratumoral treatment. This co-modality treatment significantly improved survival compared with other groups (p = 0.007). Conclusions: Multisite intratumoral therapy in tandem with systemic treatment holds promise for reducing the tumor size and enhancing the overall survival in LAPC.
Controlling a vehicle braking and longitudinal acceleration using a seeking control approach

Traditional methods for tracking the paths of driverless vehicles use plant models to determine the corresponding control laws. Due to the intricate interactions between the road and the tires, time-varying characteristics, and unidentified disturbances. It is challenging to create an accurate vehicle model. As a result, data-driven controllers, which are independent of a predetermined plant model are becoming more and more well-liked. This work implements adaptive cruise control (ACC) by employing a control approach called extremum seeking technique (EST), which is a model-free control (MFC), to control a vehicle braking and longitudinal acceleration. The main aim here is to create an ego vehicle that travels at a specific speed with maintaining a secure space with respect to a guide vehicle. A car including an ACC technique called ego car, exploits radar to determine relative velocity and relative space relating to the guiding car. The ACC technique is considered to keep maintain a relatively secure space or a preferred cruising velocity concerning the guiding vehicle. The developed model succeeded to determine the relative velocity and relative space according for the ego car to another guiding car with acceleration not more than ±2 m/s2 and spacing error less than 6 m.
A Two-Wired High Input Impedance and High CMRR Active Electrode Insensitive to Component Mismatch

This article proposes a new two-wired amplifying active electrode (AE), presenting a high input impedance and a high common-mode rejection ratio (CMRR). In the proposed structure, the input impedance and the CMRR of the system are considerably increased by extracting the body common-mode (CM) signal and applying it to AEs. Moreover, the CMRR of the proposed structure is less sensitive to the mismatch existing between voltage gains of different AEs. In addition, the power-to-noise efficiency of the system is improved because the proposed circuit presents a high-voltage gain. A prototype is implemented using discrete components for electrocardiogram (ECG) recording, while the employed passive components are selected to have a voltage gain of 100 with 1% tolerance. The measurement results show that the proposed structure achieves a 107-dB CMRR at the fundamental power-line frequency (i.e., 50 Hz) with a 1.2-<inline-formula> <tex-math notation="LaTeX">$\text{M}\Omega $ </tex-math></inline-formula> source impedance unbalance. Moreover, it presents an input-referred noise voltage equal to <inline-formula> <tex-math notation="LaTeX">$1.6~\mu \text{V}_{\text {RMS}}$ </tex-math></inline-formula> in a 0.5–100-Hz bandwidth and an input capacitance of only 2 fF.
Effets des déformations élastiques des revêtements de surface sur le comportement dynamique et la stabilité des paliers hydrodynamiques

Le travail propose dans cet article s'interesse a l'etude de l'influence de la deformabilite des revetements de surface sur les caracteristiques dynamiques et la stabilite d'un palier lisse. Les revetements consideres sont supposes monocouches et constitues par des materiaux compressibles tels que les metaux blancs. En lubrification hydrodynamique, la prise en consideration des deformations elastiques necessite le calcul des champs de pression dans le film lubrifiant et de deformations a l'interface fluide-solide. La repartition de la pression dans le film est determinee par la resolution numerique de l'equation de Reynolds avec prise en consideration de la variation de la viscosite du fluide lubrifiant avec la pression. L'hypothese de couche elastique mince permet d'utiliser le modele couche mince pour le calcul des deformations a l'interface fluide-solide. Le couplage fluide-solide en regime de lubrification elastohydrodynamique (EHD) est assure a l'aide d'un processus iteratif. La theorie lineaire est utilisee pour l'etude du comportement dynamique ainsi que la stabilite du systeme rotor-paliers. L'analyse a montre que la deformabilite des revetements a une influence non negligeable sur le comportement dynamique et la stabilite des paliers lisses; notamment les revetements de surface constitues de materiaux a faible module d'elasticite.
