Published: August 2021

Abstract
Based on the global need to efficiently eliminate highly produced amounts of sewage sludge, alternative technologies are required to be practically developed. Reduction of sewage sludge waste quantities with energy recovery is the most important and modern practice, with least possible impact on the environment. Appropriate technologies for treating and disposal sewage sludge are currently considered: incineration, gasification and pyrolysis. The main products generated during the pyrolysis process are bio-gas, bio-oil and bio-residue, providing sustainable fuels/ biofuels and adsorbents. Compared to other disposal methods of sewage sludge, pyrolysis has advantages in terms of the environment: waste in small quantities, low emissions, low level of heavy metals. From a technological point of view, pyrolysis is the most efficient in relation to its final products, pyrolysis oil, pyrolysis gas and solid residue that can be transformed into CO2 adsorbent with the help of chemical and thermal activation processes. The incineration process of sewage sludge has a number of disadvantages both environmentally and technologically: organic pollutants, heavy metals, toxic pollutants and ash resulting from combustion that needs a disposal process. A comparison of different types of sewage sludge elimination for the energy recovery is described in the present paper.

Article Highlights

Sewage sludge is a waste in increasing quantities, which requires disposal and energy recovery, in a clean way for the environment.

The pyrolysis process of sewage sludge is the cleanest method of its recovery. Pyrolysis products, bio-oil, syngas and biochar, can be used as alternative fuels to fossil fuels.

The pyrolysis process of the sewage sludge is the most advantageous from the point of view of the obtained products and of the environment, in comparison with the incineration and gasification processes.
The Deceiving Game

Published: August 2021

AbstractThe moral comparison of the three venues of deception—lying, falsely implicating, and nonverbal deception—is a central, ongoing debate in the ethics of deception. To date there has been no attempt to advance in the debate through experimental philosophy. Using methods of experimental economics, we devised a strategic game to test positions in the debate. Our article presents the experimental results and shows how philosophical analysis of the results allows drawing valid normative conclusions. Our conclusions testify against the dominant position in the debate—that lying is morally worse than all non-lying deceptions. They offer prima facie support to the view that the venue of deception makes no moral difference.

AbstractObjective:The aim of this study was to investigate the long-term outcome of quality of life (QOL) in the lower-limb amputees 10 years after the 2008 Sichuan earthquake.Methods:In the cross-sectional study, 66 lower-limb amputees were recruited. The prosthetics-related QOL was assessed using the Prosthetic Evaluation Questionnaire (PEQ) in terms of the scales of utility, appearance, sounds, residual limb health, perceived response, frustration, social burden, ambulation, and well-being. The score of each PEQ subscale was calculated and compared among the cohorts with different demographic characteristics.Results:The PEQ scores showed that the scales of sounds, residual limb health, and frustration were still low in the lower-limb amputees 10 years after the 2008 Sichuan earthquake. The comparison of PEQ scales among cohorts with different demographic characteristics indicated that the potential demographic risk factors, namely, age, marital status, educational level, living independence, and comorbidity, were associated with prosthesis-related QOL.Conclusions:The prosthesis-related QOL of the lower-limb amputees 10 years after the 2008 Sichuan earthquake has been partly documented in this study. The potential demographic risk factors associated with QOL of amputees were also identified. These findings could enhance the understanding of prosthesis-related QOL of lower-limb amputees sustained in an earthquake and facilitate the optimization of post-disaster rehabilitation strategies.

Abstract
The state of California, in the United States of America, has a population of nearly 40 million people and is the 5th largest economy in the world. During the coronavirus disease 2019 (COVID-19) pandemic in 2020-2021, the state experienced a medical surge that stressed its sophisticated health-care and public health system. During this period, ventilators, oxygen, and other equipment necessary for providing ventilatory support became a scarce resource in many health-care settings. When demand overwhelms supply, creative solutions are required at all levels of disaster management and health care. This study describes the disaster response by the state of California to mitigate the emergency demands for oxygen delivery resources.

Published: August 2021

Abstract
Microbiome, the study of microbial communities in specific environments, has developed significantly since the Human Microbiome Project began. Microbiomes have been associated with changes within environmental niches and the development of various diseases. The development of high-throughput technology such as next-generation sequencing has also allowed us to perform transcriptome studies, which provide accurate functional profiling data. Metabolome studies, which analyse the metabolites found in the environment, are the most direct environmental condition indicator. Although each dataset provides valuable information on its own, the integration of multiple datasets provides a deeper understanding of the relationship between the host, agent and environment. Therefore, network analysis using multiple datasets might give a clearer understanding of disease pathogenesis.
Catholic Political Thought and Calvinist Ecclesiology in Samuel Rutherford's Lex, Rex (1644)
Authors: Schultz Karie 
Published: August 2021

AbstractThis article presents a significant reinterpretation of an essential text in Scottish (and British) political thought, Samuel Rutherford's Lex, Rex, by analyzing its relationship with Catholic scholasticism. While scholars have observed Rutherford's use of Catholic authors, there has been no sustained analysis of how Rutherford strategically applied this intellectual tradition to the religious and political context of the British civil wars. Ideas about human liberty, the law of nations, and popular sovereignty that were developed by Catholic scholastics in the School of Salamanca allowed Rutherford to defend limited monarchy and fulfill an ecclesiological purpose in seventeenth-century Britain. He, and the majority of his Covenanter contemporaries, believed in jure divino presbyterianism: scripture mandated that elders and synods, not bishops, should rule the church. To ensure a presbyterian settlement, Rutherford needed to disprove royalist absolutists who claimed that presbyterianism threatened absolute monarchy (the divinely ordained form of civil government) by limiting royal supremacy over the church. By building on Catholic scholastic political ideas, Rutherford was able to argue that human beings could change the form of civil government and that absolute monarchy was not required by God. Ironically, to make a civil state safe for presbyterianism, Rutherford resorted to Catholic scholastics rather than those of his own confessional tradition. This analysis urges reconsideration of not only the porosity of traditional confessional boundaries in early modern political thought but the respective positions of both Calvinism and Catholicism in shaping the political ideas underlying the British revolutions of the mid-seventeenth century.
“Beasts with Claws”: The English Republic, the Presbyterian Peril, and the Ulster Question
Authors: Armstrong Robert 
Published: August 2021

AbstractAmong the multitude of enemies facing the newly born English republic, the Presbyterians of Ulster posed a threat at once ideological and military. Such supporters of the new regime as John Milton derided the “blockish presbyters” of a “remote” province and denounced them as Scottish intruders upon English soil. But the threat they posed lay not only in their capacity to mobilize an armed population but to do so around religious and political positions drawn from a common stock of ideas present across the three kingdoms. The twin dangers could be made to serve polemical purposes within domestic English debate as the Commonwealth sought to counter the religious ambitions and constitutional challenges of those they branded as “Scottified” Presbyterians. In Ulster, the short-lived Presbyterian “revolt” proved a remarkable though fleeting success. Its proponents cultivated these transplanted ideas into fertile if fragile growth in the form of armed organization and communal mobilization. This episode attests to the importance of localizing ideology in precise contexts, and to the fact that print was only one vector, if a vital one, for its transmission.
HirnantiaFauna from the Condroz Inlier, Belgium: another case of a relict Ordovician shelly fauna in the Silurian?

Published: August 2021

AbstractThe end-Ordovician mass extinction, linked to a major glaciation, led to deep changes in Hirnantian–Rhuddanian biotas. TheHirnantiaFauna, the first of two Hirnantian survival brachiopod-dominated communities, characterizes the lower–mid Hirnantian deposits globally, and its distribution is essential to understand how the extinction took place. In this paper, we describe, illustrate, and discuss the first macrofossiliferousHirnantiaFauna assemblage from Belgium, occurring in the Tihange Member of the Fosses Formation at Tihange (Huy), within the Central Condroz Inlier. Six fossiliferous beds have yielded a low-diversity, brachiopod-dominated association. In addition to the brachiopods (Eostropheodonta hirnantensis,Plectothyrella crassicosta,Hirnantiasp., andTrucizetina? sp.), one trilobite (Mucronaspissp.), four pelmatozoans (Xenocrinussp.,Cyclocharax[col.]paucicrenulatus,Conspectocrinus[col.]celticus, andPentagonocyclicus[col.] sp.), three graptolites (Cystograptus ancestralis,Normalograptus normalis, and ?Metabolograptussp.), together with indeterminate machaeridians and bryozoans were identified. The graptolite assemblage, from theAkidograptus ascensus-Parakidograptus acuminatusBiozone, indicates an early Rhuddanian (Silurian) age, and thus, an unexpectedly late occurrence of a typicalHirnantiaFauna. This Belgian association may represent an additional example of relictHirnantiaFauna in the Silurian, sharing characteristics with the only other known from Rhuddanian rocks at Yewdale Beck (Lake District, England), although reworking has not been completely ruled out. The survival of these Hirnantian taxa into the Silurian might be linked to delayed post-glacial effects of rising temperature and sea-level, which may have favored the establishment of refugia in these two particular regions that were paleogeographically close during the Late Ordovician–early Silurian.

Published: August 2021

AbstractIn the Cordillera Darwin, southernmost South America, we used 10Be and 14C dating, dendrochronology, and historical observations to reconstruct the glacial history of the Dalla Vedova valley from deglacial time to the present. After deglacial recession into northeastern Darwin and Dalla Vedova, by ~16 ka, evidence indicates a glacial advance at ~13 ka coeval with the Antarctic Cold Reversal. The next robustly dated glacial expansion occurred at 870 ± 60 calendar yr ago (approximately AD 1150), followed by less-extensive dendrochronologically constrained advances from shortly before AD 1836 to the mid-twentieth century. Our record is consistent with most studies within the Cordillera Darwin that show that the Holocene glacial maximum occurred during the last millennium. This pattern contrasts with the extensive early- and mid-Holocene glacier expansions farther north in Patagonia; furthermore, an advance at 870 ± 60 yr ago may suggest out-of-phase glacial advances occurred within the Cordillera Darwin relative to Patagonia. We speculate that a southward shift of westerlies and associated climate regimes toward the southernmost tip of the continent, about 900–800 yr ago, provides a mechanism by which some glaciers advanced in the Cordillera Darwin during what is generally considered a warm and dry period to the north in Patagonia.
HESSEL DE VRIES: RADIOCARBON PIONEER FROM GRONINGEN
Authors: Grootes Pieter M , van der Plicht Hans 
Published: August 2021

ABSTRACTHessel de Vries contributed to radiocarbon (14C) dating for only one short decade. Yet, his development of proportional CO2 counting greatly facilitated 14C measurements, improved their reproducibility, and lowered both the amount of carbon needed for a measurement and the 14C detection limit by at least a factor ten. Validating Libby’s 14C method by checking its basic assumptions with improved sensitivity, de Vries documented relatively minor violations. Natural variations in atmospheric 14C concentrations, found in tree rings, marked the start of 14C tree-ring calibration. Variable differences in 14C concentration between the atmosphere and aquatic reservoirs revealed reservoir ages, leading to further studies. De Vries applied analogue modeling to gain a better understanding of the influence of cosmogenic 14C production and the global carbon cycle, inclusive CO2 exchange across the air-water boundary, on atmospheric 14C concentrations. In close collaboration with colleagues in archaeology and geology, de Vries documented climate fluctuations and archaeological developments over the last 50,000+ years and placed them on a common 14C time scale.
Orderability of link quandles
Authors: Raundal Hitesh , Singh Mahender , Singh Manpreet 
Published: August 2021

AbstractThe paper develops a general theory of orderability of quandles with a focus on link quandles of tame links and gives some general constructions of orderable quandles. We prove that knot quandles of many fibred prime knots are right-orderable, whereas link quandles of most non-trivial torus links are not right-orderable. As a consequence, we deduce that the knot quandle of the trefoil is neither left nor right-orderable. Further, it is proved that link quandles of certain non-trivial positive (or negative) links are not bi-orderable, which includes some alternating knots of prime determinant and alternating Montesinos links. The paper also explores interconnections between orderability of quandles and that of their enveloping groups. The results establish that orderability of link quandles behaves quite differently than that of corresponding link groups.
The readability and reliability of online information about adenoidectomy
Authors: Ahmadi O , Wood A J 
Published: August 2021

AbstractObjectiveThere is limited understanding amongst patients and parents of paediatric patients regarding adenoidectomy. Most patients access health-related information online. The aim of this study was to assess the suitability of online information on adenoidectomy.MethodThe term ‘adenoid’ was used to search Google, and the first 50 websites identified were screened. For each website, the readability and quality were assessed.ResultsOf the 41 websites that met the inclusion criteria, the mean readability scores corresponded to ‘difficult to read’ and university-level reading categories. For the quality of the websites, the mean score corresponded to ‘fair’ with 39 per cent of the websites containing either ‘poor’ or ‘very poor’ quality data. The ENT UK information is one of the most readable and reliable online resources.ConclusionThe online information on adenoidectomy is largely set at an inappropriate readability level and of variable quality. Surgeons should consider assisting their patients with online searches regarding adenoidectomy.
Party competition over EU integration: asymmetrical impacts of external shocks across regions?
Authors: Huijsmans Twan , Krouwel André 
Published: August 2021

AbstractUsing Voting Advice Application (VAA) data from the EU Profiler/euandi Trend File, we studied how parties’ positions towards European integration relate to their positions on other important issues, and how this varies across EP elections, and between European regions. We hypothesized that the association between parties’ EU-integration positions and their positions on other issues was affected by the three major crises that hit the European Union (EU) between 2009 and 2019: the economic, migration, and climate crises. Additionally, we hypothesized that the economic and migration crises asymmetrically affected the association between cultural and economic issues on the one hand and the EU dimension on the other across the EU’s three macro regions (NWE, SE, and CEE). Our results show that neither the economic crisis nor the migration crisis or the climate crisis had an EU-wide impact on how European integration relates to other issue dimensions. As we hypothesized, economic issues were particularly strongly linked to EU-integration positions in SE in 2014, but our results additionally indicated that the longstanding interpretation of EU integration as a mainly economic issue in SE diminished after the start of the migration crisis. Finally, EU integration became related to immigration issues in CEE while this is not the case in the other regions. The main takeaway is that EU integration is interpreted differently by parties across the EU, which is important to recognize for parties that seek to work together in transnational party groups, and for scholars that aim to understand EU policy making.
Spurline-embedded compact hairpin-line bandpass filters for wide harmonic suppression
Authors: Das Tarun Kumar , Chatterjee Sayan 
Published: August 2021

AbstractThe current paper describes the design of a fourth-order compact narrow-band hairpin-line bandpass filter centered at 2.5 GHz and enhanced stopband suppression ~38 dB required for wireless local area network (IEEE802.11b). The size reduction of 24% has been achieved for a conventional hairpin-line filter with a second-order inward folding of the open-end arms with an improvement in the skirt characteristics. However, the folding mechanism has been overshadowed by the presence of spurious harmonics with an attenuation level of <10 dB. Subsequently, L-shaped spurlines with optimum dimensions have been incorporated in the coupled arms of the folded hairpin-line cells. Three fourth-order filters have been designed with the incorporation of spurlines in different coupling regions, fabricated, and tested experimentally. Accordingly, an extended stopband with a rejection level of 38 dB up to 4.48f0 and a size reduction of 18% over the conventional hairpin-line filter has been achieved.
Trends in the Representation of Women Among US Geoscience Faculty From 1999 to 2020: The Long Road Toward Gender Parity

AbstractInequalities persist in the geosciences. White women and people of color remain under‐represented at all levels of academic faculty, including positions of power such as departmental and institutional leadership. While the proportion of women among geoscience faculty has been cataloged previously, new programs and initiatives aimed at improving diversity, focused on institutional factors that affect equity in the geosciences, necessitate an updated study and a new metric for quantifying the biases that result in under‐representation. We compile a data set of 2,531 tenured and tenure‐track geoscience faculty from 62 universities in the United States to evaluate the proportion of women by rank and discipline. We find that 27% of faculty are women. The fraction of women in the faculty pool decreases with rank, as women comprise 46% of assistant professors, 34% of associate professors, and 19% of full professors. We quantify the attrition of women in terms of a fractionation factor, which describes the rate of loss of women along the tenure track and allows us to move away from the metaphor of the “leaky pipeline.” Efforts to address inequities in institutional culture and biases in promotion and hiring practices over the past few years may provide insight into the recent positive shifts in fractionation factor. Our results suggest a need for 1:1 hiring between men and women to reach gender parity. Due to significant disparities in race, this work is most applicable to white women, and our use of the gender binary does not represent gender diversity in the geosciences.
Arctic Ocean stratification set by sea level and freshwater inputs since the last ice age

AbstractSalinity-driven density stratification of the upper Arctic Ocean isolates sea-ice cover and cold, nutrient-poor surface waters from underlying warmer, nutrient-rich waters. Recently, stratification has strengthened in the western Arctic but has weakened in the eastern Arctic; it is unknown if these trends will continue. Here we present foraminifera-bound nitrogen isotopes from Arctic Ocean sediments since 35,000 years ago to reconstruct past changes in nutrient sources and the degree of nutrient consumption in surface waters, the latter reflecting stratification. During the last ice age and early deglaciation, the Arctic was dominated by Atlantic-sourced nitrate and incomplete nitrate consumption, indicating weaker stratification. Starting at 11,000 years ago in the western Arctic, there is a clear isotopic signal of Pacific-sourced nitrate and complete nitrate consumption associated with the flooding of the Bering Strait. These changes reveal that the strong stratification of the western Arctic relies on low-salinity inflow through the Bering Strait. In the central Arctic, nitrate consumption was complete during the early Holocene, then declined after 5,000 years ago as summer insolation decreased. This sequence suggests that precipitation and riverine freshwater fluxes control the stratification of the central Arctic Ocean. Based on these findings, ongoing warming will cause strong stratification to expand into the central Arctic, slowing the nutrient supply to surface waters and thus limiting future phytoplankton productivity.
