Abstract
Knowledge of snow cover distribution and disappearance dates over a wide range of scales is imperative for understanding hydrological dynamics and for habitat management of wildlife species that rely on snow cover. Identification of snow refugia, or places with relatively late snow disappearance dates (SDDs) compared to surrounding areas, is especially important as climate change alters snow cover timing and duration. The purpose of this study was to increase understanding of snow refugia in complex terrain spanning the rain-snow transition zone at fine spatial and temporal scales. To accomplish this objective, we used remote cameras to provide relatively high temporal and spatial resolution measurements on snowpack conditions. We built linear models to relate SDDs at the monitoring sites to topoclimatic and canopy cover metrics. One model to quantify SDDs included elevation, aspect, and an interaction between canopy cover and cold-air pooling potential. High-elevation, north-facing sites in cold-air pools (CAPs) had the latest SDDs, but isolated lower-elevation points also exhibited relatively late potential SDDs. Importantly, canopy cover had a much stronger effect on SDDs in CAPs than in non-CAPs, indicating that best practices in forest management for snow refugia could vary across microtopography. A second model that included in situ hydroclimate observations (December–February (DJF) temperature and March 1 snow depth) indicated that March 1 snow depth had little impact on SDD at the coldest winter temperatures, and that DJF temperatures had a stronger effect on SDD at lower snow depths, implying that the relative importance of snowfall and temperature could vary across hydroclimatic contexts in their impact on snow refugia. This new understanding of factors influencing snow refugia can guide forest management actions to increase snow retention and inform management of snow-dependent wildlife species in complex terrain.

Published: February 2023

Abstract
A complex of laboratory tests for water shutoff agents and their compositions as well as pilot tests were performed. It was found that a combined use of OrganoSEAL-F gel (based on seawater) and SquezeCRETE microcement meets the technical requirements to the greatest extent. The considered water shutoff technology implies deep penetration of OrganoSEAL-F gel into the flooded interval of the fractured foundation and subsequent injection of SquezeCRETE cement slurry (as a fixing composition). The proposed compositions and technologies can be used to ensure water shutoff in production wells of the White Tiger field.

Abstract
The necessity of reclamation of disturbed lands as a result of mining is substantiated. Disturbed lands lose all economic importance. In addition, they are a source of pollution of soil and air in the adjacent territories, worsen the living conditions of the population and the appearance of the landscape. The technique of drawing up the working projects for the recultivation of disturbed lands as a result of mining by using the GIS software “Panorama” is considered. The use of this software reduces the time needed to complete a project, reduces the costs and improves the accuracy of project calculations. The use of the technique is shown by the example of the recultivation of disturbed lands in the “Kushbulak” plot of the Karakhtay field. Agricultural reclamation with restoration of pastureland use is recommended. It is planned to create a beach zone with a 30 cm layer of sand in the far northwestern section. It is planned to fill the bottom of the quarry with soil to the design level and create a terrace, as well as work on the land area with a fertile soil layer of 20 cm and planning the surface. The efficiency of reclamation in parallel with the use of a mineral deposit is substantiated.

Abstract
One of the most important tasks for the agro-industrial complex of the Russian Federation is to develop methods for increasing crop seed viability. The way seeds absorb water determines the most important physicochemical processes that ensure their germination and further development of seedlings. There has been studied the impact of the magnetic field, direct and alternating current on the water absorption of cucumber and tomato seeds in the soil layer at a depth of 0.02 m. The surface current density was 0.0022 mA/cm 2, while the magnetic field induction was 3.1 mT. Within 5 hours with an interval of one hour, the seeds were removed and weighed. Direct current (negative/positive) has the greatest impact on the rate of water absorption of cucumber seeds, provided that the positive electrode is in the soil, while the negative one is on the soil surface (20.2% increase). The impact ranks second (12.7% increase), alternating current ranks third (10.1% increase). When using alternating current, the water absorption of tomato seeds increases by 80% higher, while using magnetic impact it increases by 50% than with no impact at all. There have been noted negative rates of water absorption. The results of the work can be used to develop the methods for controlling the rates of water absorption of vegetable seeds with the help of external electrophysical effects.

Published: February 2023

Abstract
It is known that a population growth in any country leads to a steady increase in demand for food and consumer goods. This demand can be met only by constantly increasing the production of agricultural products, improving their quality and increasing their variety. Therefore, in our opinion, if we take into account the limited land and water resources, which are the main means of production in agriculture, the only way to increase agricultural production will be the intensive development of this sector and its transition to an industrial basis.

Abstract
The outcomes of assessing the possibility of reducing the technogenic impact on the soil during field operations in crop production are presented by increasing the stability of the transport movement and technological means in agricultural fields. An increase in the number of passes, a distortion of the tramline shape, an increase in slippage, wobbling and sliding of technical equipment on the field lead to a significant deterioration in the topography and structure of the soil layer, which causes soil destruction and a decrease in its productivity. Transport work performed on agricultural fields leads to a significant negative technogenic impact on the soil due to the numerous passes, large transported weight, and the application of trailers. The impact on the stability of the road trains movement is considered in the paper. Characteristics of damped oscillations are used to evaluate the efficiency of impacts on stability. The method of changing the inclination angle of the turntable kingpin of the road train trailer is chosen by the method of influencing the movement stability. It is established that changing the inclination angle of the turntable kingpin of the road train trailer allows reducing the average amplitude of oscillations of the trailer front side by 26.5–28%, increasing the period of oscillations by 33.3%, and also slightly changing the decrement of oscillations by 0.5–2.5%. Therefore, structural changes in the towing device of vehicles, by providing better directional stability, will reduce the technogenic load on the soil: decrease compaction and destruction of the soil layer.

Published: February 2023

Abstract
It is known that the soils of the Bukhara oasis were formed in a dry and sharply continental climate. Therefore, the relationship between soil-forming parent rocks and groundwater is important. This article describes the natural processes that take place in this relationship, the negative effects that affect soil fertility. The article examines the mechanical composition, salinity, nutrient content, and fertility of these soils by the example of a single type of soil in Vabkent district, and describes their importance for irrigated lands.
In particular, the origin, distribution, chemical properties, productivity, as well as quality of irrigated meadow-swamp soils were determined by morphological, profile and other methods compared with the results of previous years.

Published: February 2023

Abstract
The article deals with modern issues of the application of mathematical modeling taking into account the changing parameters of the reliability of the final resource of the dock structures of the spillway construction of the Krasnodar reservoir. Hydraulic structures of the pressure front of the Krasnodar reservoir are designed and built as structures of the II capital class. Analyzing the performed mathematical modeling, we see that the sections in the wall are “dangerous” at the place where it adjoins the bottom. To perform static calculations, we select a strip with a width of 1 linear meter in the longitudinal direction. Authors apply all types of loads acting on the structure of the strip of the cross-section of the structure and determine the forces in the dangerous sections of the wall and bottom. The main one is the calculation of the structure in the transverse direction. To construct diagrams of bending moments and transverse forces in the bottom plate, with the worst-case scenario of the structure, during mathematical modeling, a model of the dock structures of the spillway construction of the Krasnodar reservoir was built and later various emergency situations under the influence of seismic loads were calculated.

Abstract
A comprehensive analysis of impacts of socio-economic development and land use on water quality is very useful for better planning and management of river basins by government. In this study, the North Canal River through a megacity-region of Beijing-Tianjin-Hebei Province in China was chosen to quantify impact of 10 socio-economic factors and 6 land use types on water quality in the watershed. The principal component regression (PCR) method was thus applied in this study to quantify effects of socio-economic development and land use types on river water quality through overcoming multicollinearity problems among influencing factors. Results showed that the water quality in the North Canal River improved significantly from serious pollution. Compared with 2010, the annual average pollution index (PI) of COD, NH3–N, TN, and TP decreased significantly in 2018, especially the PI of NH3–N decreased the most, from 8.62 in 2010 to <1 in 2018, implying that the concentration of NH3–N basically met the water quality assessment standard in 2018. The major water pollutant in the basin had shifted from NH3–N in 2010 to TN in 2018. The absolute impact coefficients of industrial restructuring, population density, upgraded municipal sewage treatment requirements (including sewage treatment rate and discharge standards of water pollutants for municipal WWTPs), and urbanization rate with COD, NH3–N and TP were higher than those of other factors, indicating that the impact of socio-economic factors on water quality was more significant than that of land use types, and the socio-economic factors may offset or alter the impact of land use on river water quality in areas disturbed by human activities.

AbstractBackgroundRestorative proctocolectomy [RPC] without a defunctioning loop ileostomy [DLI] in patients with ulcerative colitis [UC] remains controversial.AimTo compare safety and efficacy of RPC with and without DLI in patients exclusively with UC.MethodsA systematic review was performed according to PRISMA/MOOSE guidelines. Dichotomous variables were pooled as odds ratios [OR]. Continuous variables were pooled as weighted mean differences [WMD]. Quality assessment was performed using the Newcastle-Ottawa score [NOS].ResultsA total of 20 studies [five paediatric and 15 adult] with 4550 UC patients [without DLI, n = 2370, 52.09%; with DLI, n = 2180, 47.91%] were eligible for inclusion. The median NOS was 8 [range 6–9]. There was no increased risk of anastomotic leak [AL] (OR 1.13, 95% confidence interval [CI]: 0.92, 1.39; p = 0.25), pouch excision [OR 1.01, 95% CI: 0.68, 1.50; p = 0.97], or overall major morbidity [OR 1.44, 95% CI, 0.91, 2.29; p = 0.12] for RPC without DLI, and this technique was associated with fewer anastomotic strictures [OR 0.45, 95% CI: 0.29, 0.68; p = 0.0002] and less bowel obstruction [OR 0.73, 95% CI: 0.57, 0.93; p = 0.01]. However, RPC without DLI increased the likelihood of pelvic sepsis [OR 1.68, 95% CI: 1.03, 2.75; p = 0.04] and emergency reoperation [OR 1.74, 95% CI: 1.22, 2.50; p = 0.002].ConclusionRPC without DLI is not associated with increased clinically overt AL or pouch excision rates. However, it is associated with increased risk of pelvic sepsis and emergency reoperation. RPC without DLI is feasible, but should only be performed judiciously in select UC patient cohorts in high-volume, specialist, tertiary centres.
Cardiac light-chain deposition disease and hints at diagnosing: a case report
Authors: Nishioka Ryo , Yoshida Shohei , Takamatsu Hiroyuki , Kawano Mitsuhiro 
Published: February 2023

AbstractBackgroundLight-chain deposition disease (LCDD) is a systemic disorder characterized by non-amyloidotic light-chain deposition in various organs with Bence-Jones type monoclonal gammopathy. Although known as monoclonal gammopathy of renal significance, it may involve interstitial tissue of various organs, and in rare cases, proceeds to organ failure. We present a case of cardiac LCDD in a patient initially suspected of dialysis-associated cardiomyopathy.Case summaryA 65-year-old man with end-stage renal disease requiring haemodialysis presented with fatigue, anorexia, and shortness of breath. He had a history of recurrent congestive heart failure and Bence-Jones type monoclonal gammopathy. A cardiac biopsy performed for suspected light-chain cardiac amyloidosis was negative for diagnostic Congo-red stain, however, paraffin immunofluorescence examination for light-chain suggested diagnosis of cardiac LCDD.DiscussionCardiac LCDD may go undetected leading to heart failure due to lack of clinical awareness and insufficient pathological investigation. In heart failure cases with Bence-Jones type monoclonal gammopathy, clinicians should consider not only amyloidosis but also interstitial light-chain deposition. In addition, in patients with chronic kidney disease of unknown cause, investigation is recommended to rule out cardiac light-chain deposition disease concomitant with renal LCDD. Although LCDD is relatively rare it occasionally affects multiple organs; therefore, it would be better to describe it as a monoclonal gammopathy of clinical significance rather than one of renal significance.

Published: February 2023

AbstractBackgroundCardiac involvement in amyloid light-chain (AL) amyloidosis usually represents a brick in the wall of a multi-system disease. The presence of cardiac deposition of free light chains (FLCs) is the main determinant of survival. Isolated cardiac AL is an uncommon scenario characterized by a challenging diagnostic and therapeutic workup.Case summaryA 57-year-old asymptomatic man was presented for an incidental finding of myocardial necrosis at the electrocardiogram (ECG) performed for newly diagnosed arterial hypertension. Alongside signs of previous myocardial infarction, transthoracic echocardiography showed a severely increased left ventricular (LV) wall thickness not consistent with ECG voltages, segmental akinaesia with normal LV systolic function with ‘apical sparing’ pattern. Laboratory assessment showed an unexpectedly high level of natriuretic peptide and persistently abnormal troponin in the absence of symptoms or signs of heart failure or ongoing ischaemia. Coronary angiogram confirmed the coronary artery disease. Before revascularization, a complete diagnostic workup was carried. Serum electrophoresis detected a monoclonal gammopathy that was further investigated by serum immunofixation, revealing high lambda FLCs concentration. Fat pad, bone marrow, and salivary glands biopsies resulted negative for amyloid deposition. Finally, endomyocardial biopsy was consistent with AL amyloidosis. Urgent percutaneous revascularization was performed, and the patients was timely started on chemotherapy.DiscussionThe diagnosis of isolated cardiac AL amyloidosis is challenging and carries important therapeutic implications. As the short-term prognosis might be severely compromised, an accurate diagnostic flowchart has to be systematically pursued to obtain a precise diagnosis and address the optimal, tailored management.
‘Just the two of us’: single-operator interventional left atrial appendage closure—a case report
Authors: Hammerstingl Christoph , Yahya Mohammed Ali , Völz Alexander 
Published: February 2023

AbstractBackgroundDifferent procedural strategies have been published targeting to facilitate transcatheter left atrial appendage closure (LAAc). We demonstrate feasibility of a procedural set-up allowing single-operator LAAc in a selected patient.Case summaryA 87-year-old male with persistent Afib (CHA2DS2VASc, five; HASBLED, three) was referred to our hospital for LAAc. Pre-procedural planning and device sizing with three-dimensional transesophageal echocardiography (3DTEE) confirmed a non-complex anatomy of the essential anatomical structures predicting suitability for LAAc. Therefore, the procedure was performed with a simplified single-operator interventional approach. Intraprocedural TEE guidance, device preparation, and LAAc were accomplished by the interventionalist himself. For procedural guidance, the TEE probe was arranged and handled in a technique comparable to the use of intracardiac echocardiography (ICE). Procedure time (skin-to-skin) was 21 min, left atrial access time 9 min, and fluoroscopy time was 4:28 min without the use of contrast dye. The patient was discharged the following day in good medical conditions.DiscussionTo the best of our knowledge, this is the first report on successful single-operator LAAc in a selected patient. The intervention, pre-procedural screening, and intraprocedural 3D TEE were performed by one single experienced interventionalist. This simplified technique is based on a standardized pre-procedural imaging-protocol with 3D echocardiography. According to our experience, this streamlined approach is a valuable option in non-complex LAAc cases. In the growing field of structural cardiac interventions, this approach might be an interesting option for centres with limited personal and technical resources.

Abstract
Burn injury is one of the most common traumatic injuries in childhood. Fortunately, 90% of pediatric burns may be treated in the outpatient setting after appropriate burn triage. Patients with burns face significant geographic disparities in accessing expert burn care due to regionalized care. To aid patients and their families during acute outpatient burn recovery, we developed a smartphone app, Telemedicine Optimized Burn Intervention (TOBI). With this app, we aimed to increase access to care by allowing secure, streamlined communication between patients and burn providers, including messaging and wound image transfer. The purpose of this study was to systematically evaluate user feedback to optimize the patient and provider experience. TOBI was evaluated using a convergent mixed-methods approach consisting of qualitative semi-structured interviews and quantitative measurements of app usability via the mHealth App Usability Questionnaire. Participants included 15 caregivers of pediatric patients with burns who used TOBI during treatment and ten burn providers. Users found TOBI to be a highly usable application in terms of usefulness, ease of use, satisfaction, and functionality. Qualitative data provided insight into user experience, satisfaction and preferences, difficulty navigating, usability and acceptability, and potential improvements. Although most users were highly satisfied, improvements were needed to optimize the burn app. We systematically made these improvements before we released TOBI for routine patient use. This study uncovered helpful recommendations for app improvements that can be generalized to other mobile health apps to increase their appeal and adoption.
