Simulation of ash clouds after a Laacher See-type eruption
Authors: Niemeier Ulrike , Riede Felix , Timmreck Claudia 
Published: March 2021

Abstract. Dated to approximately 13 000 years ago, the Laacher See (East Eifel volcanic zone) eruption was one of the largest midlatitude Northern Hemisphere volcanic events of the Late Pleistocene. This eruptive event not only impacted local environments and human communities but probably also affected Northern Hemispheric climate. To better understand the impact of a Laacher See-type eruption on NH circulation and climate, we have simulated the evolution of its fine ash and sulfur cloud with an interactive stratospheric aerosol model. Our experiments are based around a central estimate for the Laacher See aerosol cloud of 15 Tg of sulfur dioxide (SO2) and 150 Tg of fine ash, across the main eruptive phases in May and a smaller one in June with 5 Tg SO2 and 50 Tg of fine ash. Additional sensitivity experiments reflect the estimated range of uncertainty of the injection rate and altitude and assess how the solar-absorptive heating from the fine ash emitted in the first eruptive phase changed the volcanic clouds' dispersion. The chosen eruption dates were determined by the stratospheric wind fields to reflect the empirically observed ash lobes as derived from geological, paleoecological and archeological evidence linked directly to the prehistoric Laacher See eruption. Whilst our simulations are based on present-day conditions, and we do not seek to replicate the climate conditions that prevailed 13 000 years ago, we consider our experimental design to be a reasonable approximation of the transport pathways in the midlatitude stratosphere at this time of year. Our simulations suggest that the heating of the ash plays an important role for the transport of ash and sulfate. Depending on the altitude of the injection, the simulated volcanic cloud begins to rotate 1 to 3 d after the eruption. This mesocyclone, as well as the additional radiative heating of the fine ash, then changes the dispersion of the cloud itself to be more southward compared to dispersal estimated without fine ash heating. This ash-cloud-generated southerly migration process may at least partially explain why, as yet, no Laacher See tephra has been found in Greenland ice cores. Sulfate transport is similarly impacted by the heating of the ash, resulting in stronger transport to low latitudes, later arrival of the volcanic cloud in the Arctic regions and a longer lifetime compared to cases without injection of fine ash. Our study offers new insights into the dispersion of volcanic clouds in midlatitudes and addresses a likely behavior of the ash cloud of the Laacher See eruption that darkened European skies at the end of the Pleistocene. In turn, this study can also serve as significant input for scenarios that consider the risks associated with re-awakened volcanism in the Eifel.
Technical note: A sensitivity analysis from 1 to 40 GHz for observing the Arctic Ocean with the Copernicus Imaging Microwave Radiometer

Published: March 2021

Abstract. The Copernicus Imaging Microwave Radiometer (CIMR) is one of the high-priority missions for the expansion of the Copernicus program within the European Space Agency (ESA). It is designed to respond to the European Union Arctic policy. Its channels, incidence angle, precision, and spatial resolutions have been selected to observe the Arctic Ocean with the recommendations expressed by the user communities.
In this note, we present the sensitivity analysis that has led to the choice of the CIMR channels.
The famous figure from Wilheit (1979), describing the frequency sensitivity of passive microwave satellite observations to ocean parameters, has been extensively used for channel selection of microwave radiometer frequencies on board oceanic satellite missions. Here, we propose to update this sensitivity analysis, using state-of-the-art radiative transfer simulations for different geophysical conditions (Arctic, mid-latitude, tropics). We used the Radiative Transfer Model (RTM) from Meissner and Wentz (2012) for the ocean surface, the Round Robin Data Package of the ESA Climate Change Initiative (Pedersen et al., 2019) for the sea ice, and the RTM from Rosenkranz (2017) for the atmosphere. The sensitivities of the brightness temperatures (TBs) observed by CIMR as a function of sea surface temperature (SST), sea surface salinity (SSS), sea ice concentration (SIC), ocean wind speed (OWS), total column water vapor (TCWV), and total column liquid water (TCLW) are presented as a function of frequency between 1 and 40 GHz. The analysis underlines the difficulty to reach the user requirements with single-channel retrieval, especially under cold ocean conditions. With simultaneous measurements between 1.4 and 36 GHz onboard CIMR, applying multi-channel algorithms will be facilitated, to provide the user community with the required ocean and ice information under arctic environments.

Authors: Yana Eka Andri 
Published: March 2021

Griya Seni Popo Iskandar (GSPI) merupakan salah satu galeri di Bandung yang sudah bertahan selama 40 tahun. Melalui tulisan ini, akan menganalisis sistem manajemen galeri yang mengubah format menjadi Griya Seni Popo Iskandar. Â Penelitian ini dibatasi pada periode 2016-2019, dengan pertimbangan dalam periode tersebut kegiatan pameran di GSPI memperlihatkan freukensi yang tinggi.Penelitian ini menggunakan metode kualitatif dengan menggunakan teori teori manajemen seni oleh Giep HagoortÂ yang berhubungan dengan strategi, struktur, kepemimpinan, budaya organisasi dan fungsi. Penelitian ini juga menggunakan teori medan sosial seni oleh Hans Van Maanen yang berhubungan dengan aesthetic production, audiens dan means (PAM).Berdasarkan aesthetic production yaitu seniman yang berpameran di GSPI berasal dari mahasiswa dan seniman dari masyarakat umum. Seniman yang sering berpameran adalah seniman dari Universitas Pendidikan Indonesia (UPI), selanjutnya dari Institut Seni Budaya Indonesia (ISBI), Universitas Maranatha, dan Institut Teknologi Bandung (ITB). Seniman di GSPI juga memamerkan karya yang beragam (fleksibel) dan di dominasi oleh karya kontemporer. Di samping itu GSPI memamerkan karya Popo Iskandar sebagai daya tarik bagi pengunjung. Audiens yang mengapresiasi karya di GPI berasal dari berbagai segmen, kolektor, akademisi, curator, dan pengunjung umum. Terdapat beragam tingkat pengetahuan mereka terhadap kesenirupaan. Berdasarkan means yang berkaitan dengan fsilitas GSPI, letak GSPI tidak berada di jalan utama sehingga menjadi salah satu kendala bagi pengunjung. Interior GSPI sendiri tidak terfokus pada gaya arsitektur tertentu, pengaturan tata letak masih memberikan kesan bangunan rumah.Melalui pemaparan di atas, manajemen GSPI yang dikelola oleh keluarga dan meminimalisir staf manajemen mengakibatkan penumpukan kerja pada Kurator. Perlu dilakukan evaluasi penambahan staf agar manajemen galeri dapat menajdi optimal. Berdasarkan analisis PAM pihak manajemen perlu memfokuskan target audiens yang dibidik, sehingga GSPI memiliki kekhasan tersendiri. Misalnya dengan mempertegas sebagai galeri Pendidikan. Hal ini sesuai dengan kondisi saat ini dan di sisi lain Popo Iskandar memang seorang pendidik. Karya yang dipamerkan dapat saja difokuskan pada karya-karya kontemporer sehingga menjadi sejalan dengan perkembangan Pendidikan seni saat ini. Fakor terakhir yang berkaitan dengan means adalah memperbaiki interior maupun eksterior GSPI menjadi satu gaya yang menyatu. Hal tersebut akan mempertegas karakter yang ingin disampaikan. Pihak manajemen perlu lebih kreatif dalam menjaring audiens mendatangi GSPI, salah satunya dengan mengaktifkan cafÃ© yang tersedia dan menata menjadi tempat yang nyaman serta layak ditampilkan di media social.Kata kunci : GSPI, galeri, PAM, Popo Iskandar.Â Â Â Â Â Â Â Â

The improvement of saline and sodic soils aims to reduce the dissolved salts in the soil solution. In this context, an integrated management approach is required, which not only improves its effectiveness in improving soil properties but also increases water productivity and yields.
To mitigate the negative effects of soil salinity, improvement of soil properties and yield –water productivity of rice plant, a field trial was carried out at El-Hamoul region, Kafer El-Sheikh, Egypt, during the summer seasons of 2019 and 2020. The experiments were conducted in split plot design, with three replicates. The main plots were assigned to soil amendments (control, compost (C) 10.0 Mg ha-1, gypsum (G) 100% from gypsum requirement 13.512 Mg ha-1 and G+C).Sub main plots were assigned to foliar application (control (tap water), compost tea (50 L ha-1), proline (3.6 g ha-1), and combination of compost tea + proilne).
Generally, results showed that the impacts of main plots were in the following order: compost + gypsum ˃ gypsum ˃ compost ˃ control in both growing seasons. Also, soil amendments had a significant effect on decreasing some soil chemical properties i.e. pH, EC, ESP and increasing of CEC compared control treatment. The treatment compost +gypsum more pronounced the other treatment on soil bulk density and total porosity. Soil basic infiltration rate (IR) and hydraulic conductivity (K) high significantly increased by application of compost, gypsum and gypsum + compost and recorded the highest value by application of compost + gypsum. Chlorophyll, proline content, 1000-grain weight, straw and grain yield of rice were significant increased and recorded the highest values due to the interaction between compost + gypsum and foliar of compost tea and proline during two growing seasons. Water productivity (WP) and productivity of irrigation water (PIW) for grain yield of rice were high significantly increased and recorded the highest values due to the interaction between soil amendments, compost tea and proline. Total return, net return, benefit cost ratio and total return from water unit for rice yield were significant increased with treatment and recorded highest values due the interaction compost + gypsum and foliar application of compost tea and proline.

Objective: To determine the prevalence rate of intestinal parasites/malaria co-infections and their associated risk factors in Melong and Denzo, Littoral region- Cameroon
Materials and Methods: Study period was from November 2019-March 2020. Blood samples were collected after informed consent by finger pricking. Stool samples were examined using normal saline and the Kato-Katz technique for the presence and intensity of IPs. Thick blood films were prepared, Giemsa-stained and examined under x100 for the presence of parasites and estimate GMPD. A structured questionnaire was filled out to obtain information on different factors which might predispose participants to become infected. Data was analysed using SPSS version 23 at P<0.05.
Results: The overall prevalence of IP was 28.3% (113/400). Entamoeba histolytica was the most prevalent IP 22.0% (88/400) and it was significantly more in Melong (27.7%, 76/274) than in Denzo (9.5%, 12/126), (P=0.001). The overall prevalence of malaria was 66.5% (266/400). The prevalence of malaria was higher in Denzo (79.3%, 100/126) than in Melong (60.5, 166/274), P=0.001. Children ≤5 years recorded the highest (75.4%, 83/110) prevalence of malaria, and the difference between age groups was significant, p=0.016. The overall prevalence of co-infections was 16.3% (65/400). Low access to bed nets, presence of bushes and water bodies, poor drinking water source and lack of personal and community hygiene are the associated risk factors leading to co-infection of malaria and intestinal parasites.
Conclusion: Intestinal parasites/malaria co-infections are still a cause of morbidity and mortality in Cameroon; interventions targeting groups at risk will help reduce the burden of these diseases in Melong and Denzo localities.

One of the parasitic infection faced by school age children in developing countries is intestinal parasitic infection. This study was designed to determine risk factors associated with gastrointestinal helminthic infections among school age children. A total of 600 stool samples were randomly examined by direct smear method under microscope and formol-ether concentration technique. A structured questionnaire was used to collect data on socio-noneconomic status of the children’s parents and other variables. Of this, (n=252; 42%) were found to be infected with gastrointestinal helminths infections given a breakdown of male (n=148; 24.7%) and female (n=104; 17.3%). However, there was no significant difference in prevalence among the socio-economic status. Parent whose occupation was farmer (n=169; 28%) also recorded high rate of infection, the lowest prevalence was seen among civil servants (n=19; 3%). Parents with little or no knowledge of intestinal helminths were found to be statistically significant (n=199; 33.1%, p<0.02; α =0.02) The highest rate of infection was recorded among children who had dirty finger nails (n=232; 38.6%), followed by those who walked barefooted(28.2%),then open defecation (n=147; 24.6%), hand washing after defecation (n=195; 30,7%,), habit of eating raw/roasted meat (n=136; 22.3%), hand washing before meal (n=102; 17.02%) and keeping of dirty clothes and bed linens (n=180; 30%) . Such a relatively high prevalence rate of helminthic infection in the study area could be used as a base line for the concern bodies to launch de-worming intervention campaigns.

AbstractAlthough perovskite solar cells (PSCs) have attracted enormous attention owing to their fascinating optoelectronic properties and solution processability, defects in PSCs, which adversely affect efficiency and stability, are still not completely resolved. Herein, a novel indacenodithieno[3,2‐b]thiophene‐based small molecule (SM) additive (IDTT‐ThCz), capable of interacting with perovskite layers, is developed. In particular, the IDTT‐ThCz, which can perform a surface passivation, is introduced into the perovskite layer to significantly suppress perovskite defects via antisolvent treatment. Furthermore, this facile surface passivation not only significantly improves the charge extraction capability, but also prevents perovskite degradation. The IDTT‐ThCz‐treated PSCs exhibits a power conversion efficiency (PCE) of 22.5% and retains 95% of its initial PCE after 500 h storage under thermal condition (85 °C), representing the most remarkable efficiency as well as stability among the SM additives reported to date.

Published: March 2021

AbstractBeckwith‐Wiedemann syndrome (BWS) is a genomic imprinting disorder, characterized by macroglossia, abdominal wall defects, lateralized overgrowth, and predisposition to embryonal tumors. It is caused by the defect of imprinted genes on chromosome 11p15.5, regulated by imprinting control (IC) domains, IC1, and IC2. Rarely,CDKN1Cand chromosomal changes can be detected. The aim of this study is to retrospectively evaluate 55 patients with BWS using the new diagnostic criteria developed by the BWS consensus, and to investigate (epi)genetic changes and follow‐up findings in classic and atypical phenotypes. Loss of methylation in IC2 region (IC2‐LoM), 11p15.5 paternal uniparental disomy (pUPD11), and methylation gain in IC1 region (IC1‐GoM) are detected in 31, eight, and five patients, respectively. Eleven patients have had no molecular defects. Thirty‐five patients are classified as classical and 20 as atypical phenotype. Patients with classical phenotype are more frequent in the IC2‐LoM (25/31), while patients with atypical phenotype are common in the pUPD11 group (5/8). Malignant tumors have developed in six patients (10.9%); three of these patients have IC1‐GoM, two pUPD11, one IC2‐LoM genotype, and four an atypical phenotype. We observed that the face was round in the infantile period and elongated as the child grew‐up, developing prognathism and becoming asymmetrical if hemi‐macroglossia was present in the classical phenotype. These findings were mild in the atypical phenotype. These results support the importance of using the new diagnostic criteria to facilitate the diagnosis of patients with atypical phenotype who have higher tumors risk. This study also provides important information about facial gestalt.
Frailty and Risk of Dementia in Mild Cognitive Impairment Subtypes
Authors: Ward David D. , Wallace Lindsay M. K. , Rockwood Kenneth 
Published: March 2021

Risk factors for developing dementia from mild cognitive impairment (MCI) probably differ between MCI subtypes. We investigated how frailty relates to dementia risk in amnestic MCI (a‐MCI; n = 2,799) and non‐amnestic MCI (na‐MCI; n = 629) in the National Alzheimer's Coordinating Center database. Although higher frailty increased dementia risk for people with either a‐MCI or na‐MCI, the larger risk was in na‐MCI (interaction hazard ratio = 1.35 [95% confidence interval = 1.15–1.59], p < 0.001). Even after the onset of clinically significant cognitive impairment, poor general health, quantified by a high degree of frailty, is a significant risk for dementia. ANN NEUROL 2021;89:1221–1225

Published: March 2021

AbstractThe separation ofn‐alkanes from their branched isomers is vitally important to improve octane rating of gasoline. To facilitate mass transfer, adsorptive separation is usually operated under high temperatures in industry, which require considerable energy. Herein, we present a kind of dynamic pillar‐layered MOF that exhibits self‐adjustable structure and pore space, a behavior induced by guest molecules. A combination of the flexibility of the framework with the commensurate adsorption forn‐hexane results in exceptional performance in separating hexane isomers. More significantly, lower temperature prompts the guest molecules to open the dynamic pores, which may provide a new perspective for optimized separation performance at lower temperatures with less energy consumption.

AbstractThis article reports the fabrication and characterization of porous polydimethylsiloxane (PDMS) structures developed by the solvent evaporation‐induced phase separation technique. Ternary systems containing water/tetrahydrofuran (THF)/PDMS with various concentrations are produced to form a stable solution. The porous PDMS structures are formed by removing the solvent (THF) and nonsolvent (water) phases during the stepping heat treatment procedure. The analytical ternary phase diagram is constructed based on the thermodynamic equilibrium state in the polymer solution to explain the stable/unstable formulations and the possible composition change path. The results show that the isolated pores with the adjustable pore size ranging from 330 to 1900 μm are obtained by tuning the water to the THF ratio. The mechanical properties of the porous PDMS structures are determined by conducting the tensile tests on the prepared dog bone‐shaped specimens. A wide range of elastic modulus ranging between 0.49 and 1.05 MPa was achieved without affecting the density of the porous sample by adjusting the solvent and non‐solvent content in the solution. It is shown that the flexibility of the porous structures can be improved by reducing the ratio of water to THF and decreasing the PDMS content. The porosity measurements reveal that the PDMS concentration is the major phase controlling the porosity of the structure, while the effect of water/THF is negligible.
