Abstract. Outlet glaciers that flow through the Transantarctic Mountains (TAM) experienced changes in ice thickness greater than other coastal regions of Antarctica during glacial maxima. As a result, ice-free areas that are currently exposed may have been covered by ice at various points during the Cenozoic, complicating our understanding of ecological succession in TAM soils. Our knowledge of glacial extent on small spatial scales is limited for the TAM, and studies of soil exposure duration and disturbance, in particular, are rare. We collected surface soil samples and, in some places, depth profiles every 5 cm to refusal (up to 30 cm) from 11
ice-free areas along Shackleton Glacier, a major outlet glacier of the East
Antarctic Ice Sheet. We explored the relationship between meteoric 10Be and NO3- in these soils as a tool for understanding landscape disturbance and wetting history and as exposure proxies. Concentrations of meteoric 10Be spanned more than an order of magnitude across the region (2.9×108 to 73×108 atoms g−1) and are among the highest measured in polar regions. The concentrations of NO3- were similarly variable and ranged from ∼1 µg g−1 to 15 mg g−1. In examining differences and similarities in the concentrations of 10Be and NO3- with depth, we suggest that much of the southern portion of the Shackleton Glacier region has likely developed under a hyper-arid climate regime with minimal disturbance. Finally, we inferred exposure time using 10Be concentrations. This analysis indicates that the soils we analyzed likely
range from recent exposure (following the Last Glacial Maximum) to possibly
>6 Myr. We suggest that further testing and interrogation of meteoric 10Be and NO3- concentrations and relationships in soils can provide important information regarding landscape development, soil evolution processes, and inferred exposure durations of surfaces in the TAM.

Abstract
The COVID-19 pandemic has swept the world and changed the map of education. Higher education institutions have been forced to close and hold digital learning classes to cope with governmental regulations prohibiting face-to-face interactions. This includes STIAMI Institute of Social and Management Science branch Bekasi City. With a total of 2593 students, 130 lecturers, and 60 campus administration staffs, civitas academica of Institut STIAMI Bekasi have been inevitably learning and working from home since February 2020. Such change has caused challenges and opportunities. Hence, the following paper tries to dissect students', lecturers', and campus administrations' perspectives about digital learning and teaching. The method used in the research is qualitative with case study approach, incorporating in-depth interviews and observations. Based on the results, all parties perceived full digital learning and teaching as best decision to cut the pandemic chain, although found it as a challenge and have experienced mental health and technical problems, yet found positive outcomes that lead to education without boundaries. Thus, it is recommended to hold private and group consultations; interactive workshops; local-national-international cooperations to ensure digital learning and teaching in the long run becomes bearable, productive, and beneficial for everyone involved.

Published: October 2021

Background The type of anesthesia used in total knee arthroplasty is one modifiable factor that could save hospital systems time and money. With spinal and general anesthesia having similar outcomes, more weight can be placed on these anesthesia methods’ time or money-saving aspects. Objective This study aims to determine the differences in time expenditure between spinal and general anesthesia for total knee arthroplasty to optimize OR efficiency and reduce costs. Methods A retrospective analysis of 200 unilateral total knee arthroplasty procedures (CPT Code 27447) was performed from Jan 2017 - July 2019 at one institution. 100 of these received spinal anesthesia, and 100 received general anesthesia. Patient charts were reviewed to obtain demographic, surgical, and anesthetic data. Results Time to prepare the patient for surgery and total preoperative time was significantly decreased in the general anesthesia group (24.4 minutes vs. 18.5 minutes; p=<0.0001 and 25.4 minutes vs. 20.4 minutes; p=0.012). After surgery, the time to remove the patient from the operating room was significantly decreased in the spinal group (4.8 minutes vs. 7.0 minutes; p= <0.0001). Nonoperative total time was not significantly different between the two groups (49.3 minutes vs. 46.6 minutes; p=0.1127). Conclusion While there are significant differences in certain operating room time periods between spinal and general anesthesia, these differences are effectively canceled out when considering total operating room time.
Gendered Comic Traditions: How Fanny Fern's Satire Subverts Nineteenth-Century Colonial Continuity and Enables Twenty-First Century Neocolonial Hybridity
Authors: Caron James E. 
Published: October 2021

Abstract
This article offers examples from the antebellum period that bear out Judith Lee's matters of empire framework; it exposes the ways in which American humor both continues and breaks away from its English antecedents, showing in particular how Sara Willis Parton as Fanny Fern does and does not fit into aesthetic and philosophical parameters about satire and satirists that can be traced back to English periodicals. After outlining a colonial continuity through a discussion of Parton and two contemporaries, Lewis Gaylord Clark and William Makepeace Thackeray, I go on to suggest that Parton's Fanny Fern persona also functions as a symbolic origin for a genealogy of women satirists who evoke Hélène Cixous's image of a laughing Medusa, a genealogy I describe as a neocolonial hybrid because it details American women writing satire to mock and resist the domestic imperium of US patriarchy.

Published: October 2021

La presente investigación evaluó la biomasa y el contenido de nutrientes presente en las plantaciones de Eucalyptus urograndis, a 4 edades de crecimiento (15, 34, 39 y 52 meses) en cuatro sitios, ubicadas en la provincia Padre Abad, región Ucayali. Para determinar la producción de biomasa y el almacenamiento de nutrientes, se seleccionó un individuo para cada edad, cuyo criterio de selección fue el árbol promedio procedente de la parcela de medición de 500 m2. Mediante método destructivo se obtuvieron muestras de 1 kg por elemento vegetativo como hojas superiores, hojas inferiores, ramas, corteza, madera y raíz; los cuales fueron analizados mediante espectrofotometría en la determinación de macro y micro elementos. El resultado obtenido para el contenido de biomasa por edad, es el siguiente: 15 meses (23,79 tn/ha), 34 meses (35,46 tn/ha), 39 meses (74,18 tn/ha), 52 meses (79,47 tn/ha). La diferencia de la productividad (m3/ha/año) se atribuye a la calidad de sitio, manejo, material genético y la edad. En cuanto a la extracción de los nutrientes, el calcio fue el elemento de mayor concentración en promedio sobre las 4 edades de crecimiento, seguido del potasio, nitrógeno, magnesio, sodio y fosforo. Así mismo, nitrógeno fue el elemento que tuvo mayor presencia en las hojas, sobre todo en las hojas superiores, pero también uno de los elementos con mayor movilidad.

AbstractGiven the multi-dimensionality of animal welfare, any monitoring system for slaughter animals should comprise an integrative vision that facilitates animal welfare and food safety assessment. Thus, the aim of this study was to investigate risk factors as possible causes for liver condemnations, hoof disorders, bruise prevalence, and the quality of beef carcases under commercial operating conditions in Mexico. Data were recorded for 143 journeys encompassing 1,040 commercial cattle, originating from feedlots, free-range, and dairy production systems. Details on journey distance, vehicle type, cattle type, and animals’ origin were gathered from abattoir reports. We found that carcase bruising (41%) and hoof disorders (43.9%) had the highest prevalence, regardless of the production system. Variables such as cattle type and production system influenced liver condemnations; old bulls extensively raised were more prone to present parasitosis such as Fasciola hepatica. Transportation conditions (journey distance, vehicle type) and cattle type might have influenced the development of hoof disorders in the evaluated animals. Multivariable logistic regression showed that animals’ origin was a potential risk factor for severe bruising and high muscle pH, with cull dairy cows getting the most serious damage. In general, cattle transport conditions were factors that showed interactions with three of the evaluated indicators (severe hoof injuries, carcase bruising, meat pH24h). Our study shows the need to implement integrative surveillance to identify risk factors according to the production system from which the animals originate. With this information it is possible to develop strategies to mitigate specific cattle welfare problems.
Electrify
Authors: Griffith Saul 
Published: October 2021

An optimistic—but realistic and feasible—action plan for fighting climate change while creating new jobs and a healthier environment: electrify everything.
Climate change is a planetary emergency. We have to do something now—but what? Saul Griffith has a plan. In Electrify, Griffith lays out a detailed blueprint—optimistic but feasible—for fighting climate change while creating millions of new jobs and a healthier environment. Griffith's plan can be summed up simply: electrify everything. He explains exactly what it would take to transform our infrastructure, update our grid, and adapt our households to make this possible. Billionaires may contemplate escaping our worn-out planet on a private rocket ship to Mars, but the rest of us, Griffith says, will stay and fight for the future.
Griffith, an engineer and inventor, calls for grid neutrality, ensuring that households, businesses, and utilities operate as equals; we will have to rewrite regulations that were created for a fossil-fueled world, mobilize industry as we did in World War II, and offer low-interest “climate loans.” Griffith's plan doesn't rely on big, not-yet-invented innovations, but on thousands of little inventions and cost reductions. We can still have our cars and our houses—but the cars will be electric and solar panels will cover our roofs. For a world trying to bounce back from a pandemic and economic crisis, there is no other project that would create as many jobs—up to 25 million, according to one economic analysis. Is this politically possible? We can change politics along with everything else.

Published: October 2021

Increasing populations of glyphosate-resistant Palmer amaranth [Amaranthus palmeri (S.) Wats.] have increased weed management costs for Texas High Plains cotton [Gossypium hirsutum (L.)] producers. The introduction of dicamba-tolerant cotton varieties and registration of dicamba formulations for postemergence use, combined with residual herbicides, can effectively control Palmer amaranth. Field studies were conducted in 2018 and 2019 near Lubbock, TX, USA to evaluate Palmer amaranth control and economics of weed management in dicamba-, glufosinate-, glyphosate-, and conventional cotton systems. The most consistent season-long Palmer amaranth control was achieved with the dicamba-tolerant system in both years. In 2018, greatest lint yields were achieved with dicamba-tolerant system when compared to the conventional and glufosinate-tolerant systems. In 2018, greatest gross margin above weed management costs were achieved with the dicamba-tolerant and glyphosate-tolerant systems. Greatest lint yield was achieved with the dicamba-tolerant and conventional systems in 2019 and greatest gross margins were achieved with the dicamba-tolerant system. Total variable costs were similar across all systems, with greater seed/technology and herbicide costs in dicamba-tolerant and glufosinate-tolerant systems, compared to higher tillage and hand hoeing costs in glyphosate-tolerant and conventional systems.

Published: October 2021

Amniotic bands sequence is a inherited diseases distinguished by craniofacial, body wall, and limb oddities that may be in relation with foetal-placental fibrous bands. Its pervasiveness has been delineated to range from 0.19 to 8.1 per 10 000 births [1]. It is a customary state prospectively alike with a variety of different confinements’ disability. The deformities arise in the wake of the pompous bodily part have formed usually in early evolution. The required cause of amniotic disruption complex is undisclosed .The three most usual decorative design are constriction ring syndrome signalized by one or more limbs being high-flown; the limb-body- wall complex; and amniotic band syndrome characterized by abnormalities of the head and face (craniofacial abnormalities), inadequacies of the brain and genuine deformation of the appendages [2].
The condition in few cases might be considered prior to nativity (antepartum), unlikely to change upon the sequels of explicit detailed imaging practices, like fetal USG, which may give away the feature inadequacies [3].
Here we present a case of pregnant woman admitted in our Obstetrics and gynecological department with her ultrasonography report indicative of amniotic band and further discussed about antenatal diagnosis, diagnostic and therapeutic approach, prognosis and genetic counselling of amniotic disruption complex.

Published: October 2021

AbstractFluorescence probes with aggregation‐induced emission (AIE) property are fascinating and vital in biological fields due to their bright fluorescence in the solid state. In contrast, traditional AIE materials are obscured by the off‐target effects and lack of spatial and temporal control. Photoactivatable materials with AIE characteristics, whose physicochemical behaviors can be remotely activated by light, provide great potential in biochemical information acquisition with high spatial and temporal resolution. By using AIE‐featured photoactivatable fluorescence probes, accurate analysis of the targets of interest is possible. For example, where, when, and to what extent a process is started or stopped by manipulating the non‐invasive light accurately. Thus, many researchers are enthusiastic about developing AIE‐featured photoactivatable materials and mainly focus on developing novel molecules by rational molecular structure design, and exploring advanced applications by appropriate molecular functionalization. In this review, the recent achievements of photoactivatable materials with AIE characteristics from the aspects involving inherent mechanism of photoactivity, molecular design strategy, and the corresponding applications in biological fields, are summarized. The biological applications are highlighted and discussed, including photoactivatable bioimaging, diagnosis, and photo‐controlled therapy. Finally, the challenges and prospects of the AIE‐featured photoactivatable materials are also outlined and discussed.

AbstractComplicated vessels pervade almost all body tissues and influence the pathophysiology of the human body significantly. However, current fabrication strategies have limited success at multiscale vascular biofabrication. This study reports a methodology to fabricate soft vascularized tissue at centimeter scale using multimaterial bioprinting by a customized multistage‐temperature‐control printer. The printed constructs can be perfused via the branched endothelialized vasculatures to support the well‐formed 3D capillary networks, which ensure cellular activities with sufficient nutrient supply and then mimic a mature and functional liver tissue in terms of synthesis of liver‐specific proteins. Moreover, an inner and external pressure‐bearing layer is printed to support the direct surgical anastomosis of the carotid artery to the jugular vein. In summary, a versatile platform to recapitulate the vasculature network is presented, in which case sustaining the optimal cellularization in engineered tissues is achievable.
