Who Should I Trust and Follow?
Authors: Molenaar Dorieke 
Published: February 2022

Abstract
In this article, I argue that Islamic authority is being made between online and offline environments used by young Muslims, between religious experts and ‘laymen’. Youngsters try to find their way and mosques try to direct and inform Muslims about and through online sources and strengthen their online presence. This article analyses four online discussions between young Dutch Muslims of Moroccan descent on the forum Marokko.nl. These discussions about Islamic ideologies, imams and mosques show how the participants try to convince each other of their points of view. I intend to contribute to the ongoing debates on the relationship between religion and cyberspace, and particularly on how the construct of religious authority is mediated and negotiated among youngsters by zooming into and analysing some excerpts from their online discussions.
Global Tropical Precipitation Relationships to Free-Tropospheric Water Vapor Using Radio Occultations

Published: February 2022

Abstract
The transition to deep convection and associated precipitation is often studied in relationship to the associated column water vapor owing to the wide availability of these data from various ground or satellite-based products. Based on radiosonde and ground-based global navigation satellite system (GNSS) data examined at limited locations and model comparison studies, water vapor at different vertical levels is conjectured to have different relationships to convective intensity. Here, the relationship between precipitation and water vapor in different free-tropospheric layers is investigated using globally distributed GNSS radio occultation (RO) temperature and moisture profiles collocated with GPM IMERG precipitation across the tropical latitudes. A key feature of the RO measurement is its ability to directly sense in and near regions of heavy precipitation and clouds. Sharp pickups (i.e., sudden increases) of conditionally averaged precipitation as a function of water vapor in different tropospheric layers are noted for a variety of tropical ocean and land regions. The layer-integrated water vapor value at which this pickup occurs has a dependence on temperature that is more complex than constant RH, with larger subsaturation at warmer temperatures. These relationships of precipitation to its thermodynamic environment for different layers can provide a baseline for comparison with climate model simulations of the convective onset. Furthermore, vertical profiles before, during, and after convection are consistent with the hypothesis that the lower troposphere plays a causal role in the onset of convection, while the upper troposphere is moistened by detrainment from convection.
Why the Forcing from Carbon Dioxide Scales as the Logarithm of Its Concentration
Authors: Romps David M. , Seeley Jacob T. , Edman Jacob P. 
Published: February 2022

Abstract
The radiative forcing from carbon dioxide is approximately logarithmic in its concentration, producing about 4 W m−2 of global-mean forcing for each doubling. Although these are basic facts of climate science, competing explanations for them have been given in the literature. Here, the reasons for the logarithmic forcing of carbon dioxide are explored in detail and a simplified model for the forcing is constructed. An essential component is the particular distribution of absorption coefficients within the 15-μm band of carbon dioxide. An alternative explanation, which does not depend on the spectrum of carbon dioxide but instead hinges on the tropospheric lapse rate, is shown to be neither necessary nor sufficient to explain the logarithmic forcing of carbon dioxide and to be generally inapplicable to well-mixed greenhouse gases in Earth’s atmosphere.

Abstract
This study reconstructed historical monthly rainfall data at 24 observation stations in Sumatera, Indonesia, for 22 years (1879–1900) during the Dutch colonial era. The literature research was conducted in libraries in Indonesia and the Netherlands to collect meteorological data recorded in a series of Regenwaarnemingen in Nederlandsch-Indië, which have never been reconstructed or analyzed previously. The results showed that the six western coast stations (97°–103°E, 3°N–4°S) have abundant rainfall exceeding 3000 mm yr−1, and the 10 eastern coast stations and three stations east of the Barisan ridge obtained rainfall below 3050 mm yr−1. Abundant coastal rainfall appeared only along the western coast, but not in the eastern coast and east of the Barisan ridge. The El Niño events of 1888/89 had low impact on rainfall amounts during the dry season (May–October) at the six stations of the Southern Hemispheric climate type. A significant decrease in annual dry-season precipitation was observed in 1881, 1885, and 1896. When comparing monthly data for 1931–60 and 1971–2014 at the northernmost station Banda Aceh (5.5°N, 95.3°E) and the eastern coast station Bengkalis (1.5°N, 102.1°E), a noticeable decrease and increase occurred in June–December and January–May, respectively, throughout the last century. The recent El Niño events have resulted in a decline in rainfall and dry conditions in Sumatera, but the Indian Ocean dipole had much influence on the amount of rainfall in the late-nineteenth century.

Abstract
The Rwenzori Mountains, in southwest Uganda, are prone to precipitation-related hazards such as flash floods and landslides. These natural hazards highly impact the lives and livelihoods of the people living in the region. However, our understanding of the precipitation patterns and their impact on related hazardous events and/or agricultural productivity is hampered by a dearth of in situ precipitation observations. Here, we propose an evaluation of gridded precipitation products as potential candidates filling this hiatus. We evaluate three state-of-the-art gridded products, the ERA5 reanalysis, IMERG satellite observations, and a simulation from the convection-permitting climate model (CPM), COSMO-CLM, for their ability to represent precipitation totals, timing, and precipitation probability density function. The evaluation is performed against observations from 11 gauge stations that provide at least 2.5 years of hourly and half-hourly data, recorded between 2011 and 2016. Results indicate a poor performance of ERA5 with a persistent wet bias, mostly for stations in the rain shadow of the mountains. IMERG gives the best representation of the precipitation totals as indicated by bias score comparisons. The CPM outperforms both ERA5 and IMERG in representing the probability density function, while both IMERG and the CPM have a good skill in capturing precipitation seasonal and diurnal cycles. The better performance of CPM is attributable to its higher resolution. This study highlights the potential of using IMERG and CPM precipitation estimates for hydrological and impact modeling over the Rwenzori Mountains, preferring IMERG for precipitation totals and CPM for precipitation extremes.
Multiscale Interactions Contributing to Enhanced Orographic Precipitation in Landfalling Frontal Systems over the Olympic Peninsula
Authors: Dolan Brenda , Rutledge Steven A. , Rasmussen Kristen L. 
Published: February 2022

Abstract
Orographic precipitation results from complex interactions between terrain, large-scale flow, turbulent motions, and microphysical processes. This study appeals to polarimetric radar data in conjunction with surface-based disdrometer observations, airborne particle probes, and reanalysis data to study these processes and their interactions as observed during the Olympic Mountain Experiment (OLYMPEX). Radar and disdrometer observations from OLYMPEX, which was conducted over the Olympic Peninsula in the winter of 2015, revealed 3 times as much rain fell over elevated sites compared to those along the ocean and coast. Several events were marked by significant water vapor transport and strong onshore flow. Detailed analysis of four cases demonstrated that the warm sector, which previous authors noted to be a period of strong orographic enhancement over the terrain, is associated not only with deeper warm cloud regions, but also deeper cold cloud regions, with the latter supporting the growth of dendritic ice crystals between 4 and 6 km. This dendritic growth promotes enhanced aggregation just above the melting layer, which then seeds the warm cloud layer below, allowing additional drop growth via coalescence. Periods of subsynoptic variability associated with mesoscale boundaries and low-level jets are shown to locally modify both the ice microphysics as well as surface drop-size distributions. This study explores the spatial and temporal variability of precipitation, cloud microphysics, and their relationship over the complex terrain of the Olympic Peninsula.

Significance Statement
This study appeals to polarimetric radar, aircraft particle probes, disdrometer data, and reanalysis to investigate the complex interactions between large frontal systems, terrain, and microphysical processes contributing to precipitation characteristics at the surface over the Olympic Peninsula. The study finds that the precipitation is a complex function of the synoptic regime, distance inland, and terrain height. Ice microphysical processes aloft act to modulate the surface rain drop size distributions, and are more important in contributing to higher rain accumulations inland during the later phases of the warm sector, particularly over the middle terrain heights (100–500 m).

Published: February 2022

Abstract
This study characterizes the wide range of deep convective cloud life cycles and their relationships with ambient environments observed during the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign near the Sierras de Córdoba (SDC) range in central Argentina. We develop a novel convective cell tracking database for the entire field campaign using C-band polarimetric radar observations. The cell tracking database includes timing, location, area, depth, merge/split information, microphysical properties, collocated satellite-retrieved cloud properties, and sounding-derived environmental conditions. Results show that the SDC exerts a strong control on convection initiation (CI) and growth. CI preferentially occurs east of the SDC ridge during the afternoon, and cells often undergo upscale growth through the evening as they travel eastward toward the plains. Larger and more intense cells tend to occur in more unstable and humid low-level environments, and surface-based cells are stronger than elevated cells. Midtropospheric relative humidity and vertical wind shear also jointly affect the size and depth of the cells. Rapid cell area growth rates exhibit dependence on both large environmental wind shear and low-level moisture. Evolution of convective cell macro- and microphysical properties are strongly influenced by convective available potential energy and low-level humidity, as well as the presence of other cells in their vicinity. This cell tracking database demonstrates a framework that ties measurements from various platforms centering around convective life cycles to facilitate process understanding of factors that control convective evolution.

Significance Statement
The purpose of this study is to develop a framework that ties coordinated radar, satellite, and radiosonde measurements around tracking convective storm life cycles to facilitate process understanding of atmospheric environments that control storm evolution. The processes coupling storm life cycles and local environments remain inadequately understood and are poorly represented in weather and climate models. Our results demonstrate the importance of atmospheric instability, low- and midtropospheric moisture, changes of wind with height, and interactions among nearby storms in affecting the formation and growth of convective storms. The storm database developed in this work enables future studies for comprehensive exploration of processes that lead to improved mechanistic understanding of storm evolution and their representations in models.

Purpose: This study was conducted to verify the validity and reliability of the Functional Independence Measure for Children (WeeFIM) for children with cerebral palsy by verifying the construct validity, difficulty, suitability, and cultural differences using Rasch analysis. Methods: From May 1, 2015, to February 27, 2020, 105 children with cerebral palsy aged 6 months–95 months (7 years and 11 months old) from Hospital Y located in Korea were included. In WeeFIM, 18 items were divided into 3 areas: Self-care 8 items, Motor 5 items, and Cognition 5 items. Analysis and separation reliability were analyzed. Results: In the Self-care area, the Grooming item and in the Motor area, the Transfer (Tub, Shower) item were judged as inappropriate items, and the order of difficulty was arranged without excluding the unsuitable items. In Self-acre, the most difficult item was Bathing, the easiest items were Eating and Bladder management, and the separation reliability was .87, the most difficult item in Motor was Stair, and the easiest item was Locomotion, and the separation reliability was .99. In Cognition, the most difficult item was Problem Solving, the easiest item was Communication, and the separation reliability was .95. Conclusion: The reliability and validity of WeeFIM was verified for children with cerebral palsy by applying Rasch Analysis. In future research, it is thought that additional research should be conducted by dividing the children by age and type so that they can be generalized.
High Riding Jugular Bulb Protruding Into Tympanic Cavity: Longitudinal Radiologic Study in a Deaf Child

Published: February 2022

Background High riding jugular bulb (HRJB) develops after 2 years and is rare at younger ages. High riding jugular bulb sometimes protrudes into the tympanic cavity, which can cause hemorrhagic complications during otologic surgery. Case Presentation We describe a congenitally deaf child with bilateral inner ear malformations and a right-sided HRJB on CT at 9 months. This child had undergone left cochlear implantation (CI) at 19 months, and right CI was planned at 6 years. However, we decided not to perform the right CI because preoperative CT images revealed that the right jugular bulb (JB) was enlarged and protruded into the tympanic cavity, completely covering the round window (RW). Conclusion This is the first pediatric case in which a longitudinal CT scan proves that HRJB develops and protrudes over time. These findings suggest that the earlier the HRJB forms, the larger it may grow. We must keep in mind the possibility of the enlargement and protrusion of HRJB.
Totally implantable venous access ports: A systematic review and meta-analysis comparing subclavian and internal jugular vein punctures

Published: February 2022

Background Totally implantable venous access port (TIVAP) is a completely closed intravenous infusion system that stays in the human body for a long time. It is used for the infusion of strong irritating or hyperosmotic drugs, nutritional support treatment, blood transfusion and blood specimen collection, and other purposes. There are two common ways of TIVAP: internal jugular vein implantation and subclavian vein implantation. However, the postoperative complications of the two implantation methods are quite different, and there is no recommended implantation method in the relevant guidelines. Therefore, we conducted a meta-analysis to evaluate the difference in complications of the two implantation methods, and choose the better implantation method. Methods Computer search in PubMed, Embase, Web of Science, and Cochrane Library database was conducted for randomized controlled trials (RCTs) from the establishment of the database to October 2021. Two researchers independently screened the literature according to the inclusion and exclusion criteria, extracted data, and evaluated the risk of bias in the included studies. RevMan5.4 software was used for meta-analysis. Results A total of 1086 patients in five studies were finally included. The results of meta-analysis showed that there was no significant difference in the incidence of infection (RR = 0.80, 95% CI: 0.43–1.48, p = .47), catheter blockage (RR = 0.72, 95% CI: 0.15–3.46, p = .68), port squeeze (RR = 1.07, 95% CI: 0.14–8.02, p = .95), catheter-related thrombosis (RR = 0.86, 95% CI: 0.22–3.38, p = 0.83), catheter displacement (RR = 0.50, 95% CI: 0.22–1.12, p = .09), extravasation (RR = 0.12, 95% CI: 0.01–2.15, p = .15), and catheter rupture (RR = 3.77, 95% CI: 0.16–89.76, p = .41) between the two implantation paths. Conclusions There is little difference in the complication rate of TIVAP between internal jugular vein insertion and subclavian vein insertion. Due to the small number of included studies, there are certain limitations, and more studies need to be included for analysis in the future.

Published: February 2022

Objective To investigate the risk factors of left atrial thrombus (LAT)/spontaneous echo contrast (SEC) in patients with nonvalvular atrial fibrillation (AF). Methods This retrospective study analysed the data from consecutive patients with nonvalvular AF that underwent transoesophageal echocardiography. Logistic regression analysis was performed to identify risk factors of LAT/SEC. Receiver operating characteristic curve analysis was undertaken compare the new scales with CHADS2 and CHA2DS2-VASc scores. Results A total of 558 patients with AF were included in the study. LAT/SEC was detected in 137 (24.6%) patients. The independent risk factors of LAT/SEC beyond CHADS2 or CHA2DS2-VASc scores included non-paroxysmal AF and left atrial diameter >37.5 mm. These two variables were added into the CHADS2 or CHA2DS2-VASc score to build new scales. Areas under the curve for the new scales based on CHADS2 and CHA2DS2-VASc scores were significantly higher than the CHADS2 or CHA2DS2-VASc score both in the overall study cohort and in patients at a high risk of thromboembolism. Conclusions Non-paroxysmal AF and increased left atrial diameter beyond the CHADS2 or CHA2DS2-VASc score were independent risk factors of LAT/SEC and may help to improve the current risk stratification, especially for patients with nonvalvular AF at a high risk of thromboembolism.

Authors: Macheka Lesley , Mudiwa Tatenda , Chopera Prosper , Nyamwanza Admire , Jacobs Peter 
Published: February 2022

Background: The relationship between climate adaptation strategies and nutrition security is poorly understood and often unclear. Although several adaptation strategies have been implemented to mitigate the impact of climate change, there is still a lack of conclusive evidence or studies on the interrelationships between adopted climate change adaptation strategies and nutrition outcomes. Objective: This study aimed to develop a conceptual framework that links climate change, adaptation strategies and nutrition and to show the indicators that can be used to assess the impact of climate adaptation strategies on nutrition. Methodology: The proposed conceptual framework was developed through a literature review. Results: A generic conceptual framework that could be used to assess the impact of adopted climate change adaptation strategies on nutrition outcomes was developed. The framework consists of 5 key elements: agro-food system, context characteristics, adaptation strategies, climatic shocks and stress, and system output. The principles used in designing the conceptual framework include systems approach, contingency theory, and system output. Conclusion: The developed framework offers a channel to evaluate adopted climate change adaptation strategies and their impact on nutrition outcomes. Such a conceptual framework can also be used in selecting and identifying more suitable climate adaptation strategies given specific contextual environments.

Published: February 2022

In this study, a group of injectable composite pastes with a novel formulation consisting of two inorganic components: α-calcium sulfate hemihydrate (α-CSH, P/L = 1.8–2.1 g/ml) and calcium-deficient hydroxyapatite (CDHA, P/L = 0.1 g/ml) nanoparticles; and three biopolymers: gelatin (2, 4 wt. %), alginate (1, 1.5 wt. %), and chondroitin sulfate (0.5 wt. %) were carefully prepared and thoroughly characterized with commensurate characterizations. The composite sample composed of gelatin (2 wt. %), alginate (1.5 wt. %), chondroitin sulfate (0.5 wt. %), and also CDHA nanoparticles and α-CSH with P/L ratios of 0.1 and 2.1 g/ml, respectively, exhibited optimal properties in terms of injectability, anti-washout performance, and rheological characteristics. After 14 days of immersion of the chosen sample in the simulated body fluid medium, a dense layer of apatite was formed on the surface of the composite paste. The cellular in vitro tests, such as 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay (MTT), alkaline phosphatase assay, 4ʹ,6-diamidino-2-phenylindole staining, and cellular attachment, revealed the desirable response of MG-63 cells to the composite paste. The chondroitin sulfate significantly improved the injectability, anti-washout performance, and cellular response of the samples. Considering the promising features of the composite paste prepared in this research work, it could be considered as an alternative injectable bioactive material for bone repair applications.
