Published: October 2022

Following the coronavirus infection, a variety of symptoms may persist for a long time. Therefore, an important area of further research is to study the state and response of protective immune mechanisms in the post-COVID period. Our aim was to evaluate the dynamics of mucosal immunity by measuring sIgA in the saliva samples and nasal swabs (sIgA, lactoferrin), as well as efficiency of interferon-alpha-2b (IFNa2b) treatment in the patients after coronavirus infection.
A study was conducted in the patients aged 18 to 60 years (n = 130) at the terms of 1 to 9 months after a coronavirus infection. A control group consisted of conditionally healthy individuals (n = 15). Diagnosis of post-COVID manifestations was carried out by collecting complaints, anamnestic data, physical examination and questionnaire. The state of mucosal immunity in saliva samples and nasopharyngeal mucosal scrapings was evaluated in dynamics as based on determination of sIgA and lactoferrin concentrations by means of enzyme immunoassay techniques prior to administration of local preventive therapy with recombinant IFNa2b, and 1 month after the treatment (VIFERON gel applied intranasally twice a day for 30 days).
The following symptoms of post-COVID syndrome were documented In the study group: joint and muscular pain, shortness of breath, cough, fatigue and weakness, headache and dizziness, anxiety. In the group of patients who received preventive therapy during 1 to 3 months after coronavirus infection, a significantly increased level of saliva sIgA was noted, respectively, 1.840.28 to 5.781.96 mg/mL. As based on the data obtained with scrapings from nasopharyngeal mucosa, a significant increase in the level of sIgA was revealed in the group subjected to therapy up to 3 months after COVID-19 infection, i.e., from 28.613.0 to 39.833.85 mg/mL. In the group of patients devoid of preventive therapy, a stable maintenance of the reduced mucosal immunity parameters was found in all time intervals during the period of convalescence. In all observed patients, regardless of the group, a decreased lactoferrin level was found, being two-fold lower than the normal reference values. The incidence of respiratory viral infections in the group without preventive therapy was statistically significant, being registered in 9.2% of cases.
Patients after COVID-19 infection exhibit a persistent decrease in mucosal immunity. Immunological efficacy was observed when using IFNa2b, thus making it possible to recommend it for rehabilitation in this group of patients over the period of convalescence.

Abstract. This paper deals with the variations in the Doppler spectra and in the relative amplitudes of the signals observed at oblique
incidence over the People's Republic of China (PRC) during the partial solar eclipse of 5–6 January 2019 and on reference days. The observations were made using the multifrequency multipath radio system for sounding the
ionosphere at oblique incidence. The receiver system is located at the
Harbin Engineering University, PRC, and 14 HF broadcasting station
transmitters are used for taking measurements along the following radio-wave propagation paths: Lintong/Pucheng to Harbin, Hwaseong to Harbin, Chiba/Nagara to Harbin, Hailar/Nanmen to Harbin, Beijing to Harbin (three paths), Goyang to Harbin, Ulaanbaatar/Khonkhor to Harbin, Yakutsk to Harbin (two paths), Shijiazhuang to Harbin, Hohhot to Harbin, and Yamata to Harbin. The specific feature of this partial solar eclipse was that it occurred during the local morning with a geomagnetic disturbance (Kp ≈ 3−) in the background. The response of the ionosphere to the solar eclipse has been inferred from temporal variations in the Doppler spectra, the Doppler shift, and the signal relative amplitude. The partial solar eclipse was found to be associated with broadening of the Doppler spectrum, up
to ± 1.5 Hz, alternating sign Doppler-shift variations, up to ± 0.5 Hz, in the main ray, and quasi-periodic Doppler-shift changes. The relative amplitude of electron density disturbances in the 15 min period of atmospheric gravity wave field and in the 4–5 min period of infrasound wave field is estimated to be 1.6 %–2.4 % and 0.2 %–0.3 %, respectively. The estimates of a maximum decrease in the electron density are in agreement with the observations.
Impacts of different types of El Niño events on water quality over the Corn Belt, United States

Abstract. The United States Corn Belt region, which primarily includes two large basins, namely, the Ohio–Tennessee River basin (OTRB) and the Upper Mississippi River basin (UMRB), is responsible for the Gulf of Mexico hypoxic zone. Climate patterns such as El Niño can affect the runoff and thus the water quality over the Corn Belt. In this study, the impacts of eastern Pacific (EP) and central Pacific (CP) El Niño events on water quality over the Corn Belt region were analyzed using the Soil and Water Assessment Tool (SWAT) models. Our results indicated that, at the outlets, annual total nitrogen (TN) and total phosphorus (TP) loads decreased by 13.1 % and 14.0 % at OTRB and 18.5 % and 19.8 % at UMRB, respectively, during the EP El Niño years, whereas during the CP El Niño years, they increased by 3.3 % and 4.6 % at OTRB and 5.7 % and 4.4 % at UMRB, respectively. On the subbasin scales, more subbasins showed negative (positive) anomalies of TN and TP during EP (CP) El Niño. A seasonal study confirmed that water quality anomalies showed the opposite patterns during EP and CP El Niño years. At the outlet of OTRB, seasonal anomalies in nutrients matched the El Niño–Southern Oscillation (ENSO) phases, illustrating the importance of climate variables associated with the two types of El Niño events on water quality in the region. At the UMRB, TN and TP were also influenced by agricultural activities within the region, and their anomalies became greater in the growing seasons during both EP and CP El Niño years. A quantitative analysis of precipitation, temperature, and their effects on nutrients suggested that precipitation played a more important role than temperature did in altering the water quality in the Corn Belt region during both types of El Niño years. We also found specific watersheds (located in Iowa, Illinois, Minnesota, Wisconsin, and Indiana) that faced the greatest increases in TN and TP loads and were affected by both the precipitation and agricultural activities during the CP El Niño years. The information generated from this study may help proper decision-making for water environment protection over the Corn Belt.

Published: October 2022

Abstract. The Columbia River Treaty (CRT) signed between the United States and Canada in 1961 is known as one of the most successful transboundary water
treaties. Under continued cooperation, both countries equitably share collective responsibilities of reservoir operations and flood control and
hydropower benefits from treaty dams. As the balance of benefits is the key factor of cooperation, future cooperation could be challenged by
external social and environmental factors which were not originally anticipated or change in the social preferences of the two actors. To understand
the robustness of cooperation dynamics, we address two research questions. (i) How does social and environmental change influence cooperation
dynamics? (ii) How do social preferences influence the probability of cooperation for both actors? We analyzed infrastructural, hydrological,
economic, social, and environmental data to inform the development of a socio-hydrological system dynamics model. The model simulates the dynamics
of flood control and hydropower benefit sharing as a function of the probability to cooperate, which in turn is affected by the share of
benefits. The model is used to evaluate scenarios that represent environmental and institutional change and changes in political characteristics
based on social preferences. Our findings show that stronger institutional capacity ensures equitable sharing of benefits over the long term. Under the current CRT, the utility of cooperation is always higher for Canada than non-cooperation, which is in contrast to the United States. The probability to
cooperate for each country is lowest when they are self-interested but fluctuates in other social preference scenarios.
Physically based modeling of co-seismic landslide, debris flow, and flood cascade
Authors: van den Bout Bastian , Tang Chenxiao , van Westen Cees , Jetten Victor 
Published: October 2022

Abstract. The 2008 Wenchuan earthquake lead to various complex
multi-hazard chains that included seismically triggered landslide
initiation, landslide runout, river damming, dam breaching, and flooding.
The modeling of the interactions between such hazardous processes is
challenging due to the complexity and uncertainty. Here we present an
event-based physically based model that is able to simulate multi-hazard
land surface process chains within a single unified simulation. The final
model is used to simulate a multi-hazard chain event in the Hongchun
watershed, where co-seismic landslides led to a landslide dam and, 2 years
later, a debris flow that breached the landslide dam. While most aspects of
the multi-hazard chain are predicted well, the correct prediction of slope
failures remains the biggest challenge. Although the results should be
treated carefully, the development of such a model provides a significant
progress in the applicability of multi-hazard chain simulations.
