ABSTRACTLarge bolide impacts seem to have strongly affected biological evolution, causing detrimental effects on the biosphere. The best-known case is the Chicxulub impact (Yucatan Peninsula, Mexico), the most probable trigger of the Cretaceous/Paleogene boundary (KPB) mass extinction. Nevertheless, after four decades of intensive research, a consensus on the causal relationship between the impact and the mass extinction has not yet been reached. Most of the scientific community has established multiple, strong arguments for the Chicxulub impact as the most likely and principal cause of the KPB mass extinction. However, a variety of hypotheses link the mass extinction mainly to the volcanism of the Deccan Traps and one or more bolide impact events within a relatively short time through the KPB: one impact in the late Maastrichtian (66.3 Ma), corresponding to the Chicxulub impact, a larger one at the KPB (66 Ma), and a final one in the early Danian (65.9 Ma).Here, we report on the controversies relating to the correlation of the Chicxulub impact event with the mass extinction, with a focus on the stratigraphy and biostratigraphy of sections in Mexico, Cuba, and Haiti, which include ejecta-rich clastic deposits linked to the Chicxulub impact. High-resolution biostratigraphy and quantitative data with planktic foraminifera reveal that these deposits are synchronous with the ejecta-rich airfall layer and the KPB mass extinction horizon of the El Kef, Tunisia, stratotype. Our results provide no support for a multiple impact scenario but confirm that the Chicxulub impact event is indeed the KPB impact event. Furthermore, we have not found any biostratigraphic evidence to support an additional Danian impact event near the Gulf of Mexico region.

ABSTRACT
Travertine deposits preserved within ancient aqueduct channels record information about the hydrology, temperature, and chemistry of the flowing water from which they precipitated. However, travertine is also chemically reactive and susceptible to freshwater diagenesis, which can alter its original composition and impact reconstructions of aqueduct operation, maintenance, and climate. Hydraulic reconstructions, in combination with a suite of high-resolution optical, laser, electron, and X-ray microscopy analyses, have been used to determine the original crystalline structure and diagenetic alteration of travertine deposited in the Anio Novus aqueduct built in A.D. 38–52 at Roma Vecchia. Age-equivalent travertine deposits, precipitated directly on the mortar-covered floor at upstream and downstream sites along a 140-m-long continuous section of the Anio Novus channel, exhibit consistent crystalline textures and stratigraphic layering. This includes aggrading, prograding, and retrograding sets of travertine linguoid, sinuous, and hummocky crystal growth ripples, as well as sand lags with coated siliciclastic grains deposited on the lee slope of ripple crests. The original aqueduct travertine, which is similar to travertine formed in analogous natural environments, is composed of shrub-like, dendritically branching aggregates of 1–3-μm-diameter euhedral calcite crystals. Dark brown organic matter-rich laminae, formed by microbial biofilms and plant debris, create stratigraphic sequences of high-frequency, dark–light layering. This hydraulic and petrographic evidence suggests that large, radiaxial calcites diagenetically replaced the original aqueduct travertine shrubs, forming upward-branching replacement crystals that crosscut the biofilm laminae. While this diagenetic process destroyed the original crystalline fabric of the calcite shrubs, the entombed biofilm laminae were mimetically preserved. These integrated approaches create the type of depositional and diagenetic framework required for future chemostratigraphic analyses of travertine deposited in the Anio Novus and other ancient water conveyance and storage systems around the world, from which ancient human activity and climatic change can be more accurately reconstructed.
Vortices in Polar and β Phases of 3He
Authors: Volovik G. E. 
Published: March 2022

Recently, a new topological phase of superfluid 3He called the β phase has been obtained by strong polarization of the nematic polar phase. We consider half-quantum vortices, which are formed in rotating cryostat, and discuss the evolution of the vortex lattice in the process of the transition from the polar phase to the β phase via the spin-polarized polar phase.
Cerebrospinal fluid fistula after combined spinal-epidural block

Published: March 2022

Neuraxial anaesthesia is an essential technique in obstetric anaesthesia practice. Cerebrospinal fluid (CSF) fistula is a rare complication and there is no consensus about its clinical approach. We present a case of a 28-year-old nulliparous woman that developed a cutaneous CSF fistula following combined spinal and epidural block for caesarean delivery. After multidisciplinary discussion it was decided that hydration, absolute bed-rest and compressive dressing with abdominal binder was the best option and the patient fully recovered without any sequelae.Based on literature, symptoms of intracranial hypotension and leakage of clear fluid surrounding the puncture site usually motivate referral to anaesthesia. Management strategies can be both conservative and invasive, including direct suture of the skin puncture site and epidural blood patch.Regarding the anaesthesia practice on this topic, most of the available evidence is based on case reports, rendering the decision-making process challenging.

Authors: Bharwani Nandlal , Choudhary Pradeep , Jain Hemant , Raichandani Kishore , Godara Jagdish , Saxena Medhavi 
Published: March 2022

Introduction: Subtalar dislocation is a rare injury around foot and ankle. Most common mode of injury is high-energy trauma (road traffic accident (RTA), fall from height (FFH) and sports activities) (Saini R, Dhillon MS, Gill SS. Congenital subtalar dislocation — a case report. Foot 19; Kaufmann RA, Davidson R, McCarthy J. Bilateral congenital subtalar dislocation: a case report. Clin. Orthop. Related Res. 397). It is commonly seen in young men and the mechanism is inversion injury in plantar-flexed foot. Medial-type dislocation is most commonly seen with incidence between 65% and 85%, as stated in various studies. Pure ligamentous injuries have shown good prognosis, which when associated with fractures can affect the functional outcome. Methods: We conducted a prospective study from 1st January 2017 to 1st December 2020 including seven patients (five males and two females) with closed medial subtalar dislocation with (1) or without fractures (6). In our study, closed reduction was performed in all the cases. At final follow-up, functional outcome was evaluated using ‘AOFAS-AHFS Score’ and radiological assessment. Results: All seven patients had good functional outcome at final follow-up and found no difficulty in doing daily routine activities. Routine clinical and radiological assessments were also done at final follow-up. All patients had complete ROM at final follow-up. Conclusion: Closed medial subtalar dislocation without significant articular fractures has good outcome in terms of function if managed properly.

Published: March 2022

Background:
Patients with diabetes have accelerated atherosclerosis progression, but the underlying mechanisms are not fully understood. Dynamic contrast-enhanced magnetic resonance imaging has allowed in vivo characterization of plaque neovasculature, which plays a critical role in plaque progression. We aimed to evaluate the impact of diabetes on carotid plaque neovasculature as assessed by dynamic contrast-enhanced magnetic resonance imaging.

Methods:

Patients with recent ischemic stroke and ipsilateral carotid plaque underwent multicontrast magnetic resonance imaging for characterizing plaque morphology and dynamic contrast-enhanced magnetic resonance imaging for pharmacokinetic parameters of plaque neovasculature, including transfer constant (

K

, reflecting flow, endothelial surface area, and permeability) and fractional plasma volume (
ν

).

Results:

Sixty-five patients were enrolled, including 30 patients with diabetes (years since diagnosis: median 5.0 [interquartile range, [3.0–12.0]) and 35 patients without diabetes. Subjects with diabetes had a greater plaque burden and a higher prevalence of high-risk characteristics. Additionally, carotid plaques in the subjects with diabetes showed higher

than those in the subjects without diabetes (0.100±0.048 min

,
P

ν

p

was numerically lower in the subjects with diabetes (5.2±3.7% versus 6.2±4.3%,
P
=0.31). The association of diabetes with high

K
trans

(β=0.033,
P
=0.005) was independent of patient and plaque characteristics and remained largely intact after adjusting for serum lipids, glucose, or hs-CRP (high-sensitivity C-reactive protein). However, it became nonexistent after adjusting for hemoglobin A1c (β=−0.010,
P
=0.49).

Conclusions:
Dynamic contrast-enhanced magnetic resonance imaging of carotid plaques suggested that plaque neovasculature in patients with diabetes is leaky, indicating enhanced capability of bringing blood constituents and facilitating extravasation of inflammatory cells, erythrocytes, and plasma proteins. Leaky plaque neovasculature correlated with hemoglobin A1c and may play a role in accelerated atherosclerosis progression in diabetes.
Deploying an Ethnographic Sensibility to Understand Climate Change Governance: Hanging Out, Around, In, and Back
Authors: Vanhala Lisa , Johansson Angelica , Butler Frances 
Published: March 2022

AbstractWhat can an “ethnographic sensibility” contribute to research on climate change governance? With its emphasis on meaning making and understanding what may lie beneath more obvious interactions and processes, ethnographic methodologies, particularly collaborative event ethnography, are increasingly deployed to address complex questions and achieve conceptual leverage on issues related to climate governance. Drawing on literature in climate anthropology, material geography, and political ethnography, and with examples from our own fieldwork experiences, we devise a heuristic typology underpinned by an ethnographic sensibility to help guide the fieldwork phase of a research project. Building on the well-established practice of hanging out, we introduce hanging around, which attends to spatiality and matter; hanging in, which addresses issues of access and trust; and hanging back to guide the practice of reflexivity. We articulate what fieldwork with an ethnographic sensibility entails and discuss its potential and implications for climate governance research.
John’s Visionary Experience as an Interpretive Key to the Book of Revelation
Authors: Neal Joel 
Published: March 2022

Abstract
The author asserts that prophetic visionary experience is the primary and sole method of disclosure in the Apocalypse and has crucial relevance for New Testament studies. He argues that John’s visionary state was an altered state of consciousness with stream of consciousness affinities. This sheds invaluable light on Revelation in eight significant areas: 1) the fluid past/present/future shifting of tenses, 2) the fluid spatial dimension found in Revelation, 3) the ability to see into the invisible spirit realm, 4) an enhanced auditory or hearing component in the series of visions, 5) a greatly enhanced emotional intensity, 6) a distinct transport in the Spirit component, 7) pronounced interaction between John, the four Living Beings, the angels, the 24 Elders, the glorified saints in heaven, Jesus, and God the Father, and 8) an increased awareness of God’s glory and majesty in the context of the heavenly worship.
Taking Ownership of Our Spirituality
Authors: Åkerlund Truls 
Published: March 2022

Abstract
This article accentuates the need for leadership metaphors that align with an organization’s ethos and suggests the liturgical director as a viable metaphor for leadership in Pentecostal worship and spirituality. Borrowing its meaning from the world of film and theatre, the director metaphor denotes a person who tells actors how to play their parts, hence emphasizing the reciprocal relationship between the director (ecclesial leader), actors (congregants), and script (Scripture). Approaching leadership from this perspective provides a starting point for discussions on collaborate sensemaking and co-constructed leadership in Pentecostal congregations and allows for analyses of influence in Pentecostal leadership beyond the taxonomies of behavioral leadership studies.
Ngoma in Tanzania and Goma in Gujarat: Do You Know That This Ritual Practice Connects Tanzania and India?
Authors: Mapana Kedmon E. 
Published: March 2022

Abstract
This paper exposes a ritual practice that can create a potential cultural collaboration between Tanzania and India. In support of enculturation theory, the author argues that if Tanzanian and Indian governments promote ngoma musical arts in Tanzania and goma musical arts in Gujarat, India, cultural collaboration in music could be enhanced between the two countries. This paper briefly presents pertinent historical and cultural background of the two countries, and discusses empirical research that provides evidence of the close linkage between ngoma musical arts in Tanzania and goma musical arts in Gujarat, India. This paper is intended as foundational not only for artistic and intellectual exchange and collaboration between two regions, but also as a means of considering ways to foster social and economic development between artists and scholars of Tanzania and India.
Analysis of Economic Effect of COVID-19 Pandemic on the Kenyan Economy
Authors: Siringi Elijah Mirwoba 
Published: March 2022

Abstract
COVID-19 virus can be described as one of the worst global pandemic ever experienced in the 21st Century. Focusing on the pandemic the study main objective was to analyze direct and indirect economic effect of COVID-19 pandemic and establish the extent to which the virus has affected Kenya’s key economic sectors contributing to the country’s GDP. The study adopts a content analysis approach whose aim is to describe COVID-19 phenomenon. The study relies on diverse secondary database not limited to: World Health Organization (WHO) on COVID-19 trends, IMF, UNDP, Central Bank of Kenya (CBK), KNBS, IPAR, ICA and KIPPRA among others. Data Analysis results reveal that COVID-19 poses an unprecedented shock by disrupting economic activity. Kenya’s current account deficits has declined drastically in capital flows. The GDP in 2020 shrank to 1.1% from. 5.7% .The country is also experiencing risk of collapse of health systems that is under pressure from spread of the virus; households have fallen into poverty; and a huge number of losses of employment have been experienced across all sectors estimated to about 4.64 million. Whereas the Kenyan Government focuses on re-engineering the economy by implementing economic stimuli package of fiscal, monetary, wage, and social protection policies aimed to arrest the economic recession. The study recommends that the government may consider sovereign debt restructurings; expansion of loan programs to firms and households in the formal sector and cash transfers to cushion vulnerable households in the informal sector and promote recovery of the economy.
A Meshwork of Melodies: Des-making Through the Singing and Wayfaring of Shah Abdul Latif’s Devotees
Authors: Huang Pei-ling 
Published: March 2022

Abstract
This article imagines a conception of Sindh that rejects the bounded ethnolinguistic region created through colonial-modern philology and administration. I explore affective geographies produced through singing, storytelling, and traveling in relation to the poetry of Sufi mystic Shah Abdul Latif Bhittai (1689–1752) by his past and present devotees, drawing on the idea of region as a meshwork of movements created through lived lines of wayfaring, to borrow a concept from Tim Ingold. Focusing on the melodic chapters of verses (Surs) in Shah Jo Rāg, a repertoire for singing Latif’s poetry by specialist devotees (rāgī faqīrs), I reconstruct two kinds of movement. First, traces of historical movement from less-acknowledged Surs in Shah Jo Rāg and the Ganj, an early manuscript. Second, contemporary movements inspired by Surs based on two popular romances, from the narratives of Latif’s devotees. These movements reveal processes of des-making: creating entanglements to a relational and cumulative des (“land, country”).
Transit Time Distributions and Ventilation Pathways Using CFCs and Lagrangian Backtracking in the South Atlantic of an Eddying Ocean Model
Authors: Chouksey Manita , Griesel Alexa , Eden Carsten , Steinfeldt Reiner 
Published: March 2022

Abstract
Transit time distributions (TTDs) for the Antarctic Intermediate Water (AAIW) in the South Atlantic Ocean are estimated from an eddying ocean model with a twofold scope: validation of the TTD method and identifying pathways of the AAIW. The TTDs are inferred both from Lagrangian particle backtracking and the modeled CFC-11 concentrations, under the assumption that the TTDs can be described with an inverse Gaussian function. A bimodal distribution is obtained for the Lagrangian TTDs with four major subduction regions identified: near the Agulhas retroflection, south of New Zealand, west of the Drake Passage (smallest mean age Γ = 13 years), and in the Argentine basin (largest mean age Γ = 25 years). With the Southern Ocean as source region, the inverse Gaussian is a reasonable representation for the TTDs in the eastern Atlantic basin (40°–35°S, 0°–20°E), whereas the fit for region west (40°–35°S, 60°–40°W) of the mid-Atlantic ridge is not as good and overestimates the TTDs for transit times < 15 years. Mean ages from the modeled CFC-11 are mostly larger (up to 12 years) in the eastern Atlantic basin, and they are mostly smaller than the Lagrangian mean ages in the west. Both methods yield mean ages smaller in the western than in the eastern Atlantic basin and an aging of AAIW from the 1990s to the 2000s that is consistent with reduced flow velocities. The Antarctic Circumpolar Current appears to be the prime determinant of the transit times. The results suggest that the inverse Gaussian, despite assuming 1D advection–diffusion with constant mean flow and diffusivity, is a surprisingly good fit.

Significance Statement
In this article, we assess the transit time distribution method, often used to estimate anthropogenic carbon uptake in the ocean from observations, thereby exploring particle pathways from the surface into the ocean interior in the South Atlantic Ocean. We track thousands of particles in a model from their point of origin near the surface to the ocean interior. The tracking reveals multiple routes and gives the actual travel time of these particles, which we compare with the travel times predicted by theory. Thus, this research deepens our understanding of the routes and travel times of the water particles, which is important for the ocean circulation, and provides insights to improve the methods to infer anthropogenic carbon uptake, storage, and transport.
Comparative study of coronary artery bypass grafting combined with off-pump mitral valvuloplasty versus coronary artery bypass grafting alone in patients with moderate ischemic mitral regurgitation
Authors: Liu Shuo , Wang Liangshan , Li Jingxing , Gu Chengxiong 
Published: March 2022

Introduction Whether mitral surgery should be performed simultaneously with coronary artery bypass grafting (CABG) in patients with moderate ischemic mitral regurgitation (MIMR) is controversial. This study was performed to introduce a method of off-pump mitral valvuloplasty after off-pump CABG (OPCABG) and compare it with OPCABG alone. Methods Eighty-three patients with MIMR underwent OPCABG. Among them, 21 patients (Group A) underwent posterior mitral annuloplasty without cardiopulmonary bypass, and 62 patients (Group B) underwent OPCABG alone. The primary endpoint of follow-up was the mitral regurgitation area. Results The mean mitral regurgitant area in Group A and B was 6.42 ± 1.02 and 5.49 ± 1.24 cm2 preoperatively ( p = .479), 2.93 ± 1.35 and 3.28 ± 1.93 cm2 at 1 week postoperatively ( p = .516), 3.06 ± 2.16 and 3.09 ± 1.85 cm2 at 3 months postoperatively ( p = .839), and 3.02 ± 1.60 and 3.7 cm2 (median) at 1 year postoperatively ( p = .043). There was less regurgitation in Group A at the mid-term. Intragroup comparison showed significant differences between the preoperative and postoperative values in both groups, with no difference in the regurgitant area at each postoperative time point in Group A but a significant difference between 3 months and 1 year postoperatively in Group B ( p = .042). Multiple linear regression showed that the mid-term mitral regurgitant area changes were negatively correlated with graft flow and positively correlated with age. Conclusion In patients with MIMR who underwent OPCABG plus off-pump mitral valve annuloplasty, the mitral regurgitant area was smaller and mitral regurgitation recurrence was less frequent at the mid-term follow-up.

Published: March 2022

Background This systematic review assesses the effectiveness of physiotherapy on headache parameters and quality of life of patients with tension-type headache using network meta-analysis. Methods A systematic search was conducted in the databases Web of Science, Medline, Cochrane Library and Physiotherapy Evidence Database up to August 2021. Randomised controlled trials investigating the effect of physiotherapy on tension-type headache were included. Risk of bias assessment was performed using the Risk of bias tool 2.0. Results were presented according to the Cochrane handbook and the PRISMA statement. Results Twenty reports were eligible and 15 were included in network meta-analysis for pain intensity and frequency. Transcutaneous electrical stimulation combined with physiotherapy was the most effective approach to reduce pain intensity compared to control (mean difference (MD): −4.18, moderate confidence) and usual care (MD: −3.8, moderate confidence) Manual therapy (joint mobilisation) plus exercise was the most effective intervention to reduce headache frequency compared to control (MD: −13.03, low confidence) and usual care (MD: −13.95, moderate confidence). Conclusion Results suggest a combination of passive physiotherapy techniques with exercise and/or transcutaneous electrical stimulation as the most effective physiotherapy intervention to reduce pain intensity and frequency in the short term. More research is needed to investigate mid-term and long-term effects.
