Published: June 2022

Abstract. Annually laminated lake sediment can track paleoenvironmental change at high resolution where alternative archives are often not available. However,
information about the chronology is often affected by indistinct and intermittent laminations. Traditional chronology building struggles with these
kinds of laminations, typically failing to adequately estimate uncertainty or discarding the information recorded in the laminations entirely,
despite their potential to improve chronologies. We present an approach that overcomes the challenge of indistinct or intermediate laminations and
other obstacles by using a quantitative lamination quality index combined with a multi-core, multi-observer Bayesian lamination sedimentation model
that quantifies realistic under- and over-counting uncertainties while integrating information from radiometric measurements (210Pb,
137Cs, and 14C) into the chronology. We demonstrate this approach on sediment of indistinct and intermittently laminated
sequences from alpine Columbine Lake, Colorado. The integrated model indicates 3137 (95 % highest probability density range: 2753–3375) varve
years with a cumulative posterior distribution of counting uncertainties of −13 % to +7 %, indicative of systematic observer
under-counting. Our novel approach provides a realistic constraint on sedimentation rates and quantifies uncertainty in the varve chronology by
quantifying over- and under-counting uncertainties related to observer bias as well as the quality and variability of the sediment appearance. The approach
permits the construction of a chronology and sedimentation rates for sites with intermittent or indistinct laminations, which are likely more
prevalent than sequences with distinct laminations, especially when considering non-lacustrine sequences, and thus expands the possibilities of
reconstructing past environmental change with high resolution.

Published: June 2022

Abstract. The Community Earth System Model (CESM) developed by the
National Center for Atmospheric Research (NCAR) has been used worldwide for
climate studies. This study extends the efforts of CESM development to
include an online (i.e., in-core) ensemble coupled data assimilation system
(CESM-ECDA) to enhance CESM's capability for climate predictability studies
and prediction applications. The CESM-ECDA system consists of an online
atmospheric data assimilation (ADA) component implemented in both the
finite-volume and spectral-element dynamical cores and an online ocean
data assimilation (ODA) component. In ADA, surface pressures (Ps) are
assimilated, while in ODA, gridded sea surface temperature (SST) and ocean
temperature and salinity profiles at real Argo locations are assimilated.
The system has been evaluated within a perfect twin experiment framework,
showing significantly reduced errors of the model atmosphere and ocean
states through “observation” constraints by ADA and ODA. The weakly coupled data assimilation (CDA) in
which both the online ADA and ODA are conducted during the coupled model
integration shows smaller errors of air–sea fluxes than the single ADA and
ODA, facilitating the future utilization of cross-covariance between the
atmosphere and ocean at the air–sea interface. A 3-year CDA reanalysis
experiment is also implemented by assimilating Ps, SST and ocean
temperature and salinity profiles from the real world spanning the period
1978 to 1980 using 12 ensemble members. The success of the online CESM-ECDA
system is the first step to implementing a high-resolution long-term climate
reanalysis once the algorithm efficiency is much improved.
Description and evaluation of the tropospheric aerosol scheme in the Integrated Forecasting System (IFS-AER, cycle 47R1) of ECMWF

Published: June 2022

Abstract. This article describes the Integrated Forecasting System aerosol scheme (IFS-AER) used operationally in the IFS cycle 47R1, which was operated by the European
Centre for Medium Range Weather Forecasts (ECMWF) in the framework of the Copernicus Atmospheric Monitoring Services (CAMS). It represents an update
of the Rémy et al. (2019) article, which described cycle 45R1 of IFS-AER in detail. Here, we detail only the parameterisations of sources and sinks that
have been updated since cycle 45R1, as well as recent changes in the configuration used operationally within CAMS. Compared to cycle 45R1, a
greater integration of aerosol and chemistry has been achieved. Primary aerosol sources have been updated, with the implementation of new dust and
sea salt aerosol emission schemes. New dry and wet deposition parameterisations have also been implemented. Sulfate production rates are now
provided by the global chemistry component of IFS. This paper aims to describe most of the updates that have been implemented since cycle 45R1,
not just the ones that are used operationally in cycle 47R1; components that are not used operationally will be clearly flagged. Cycle 47R1 of IFS-AER has been evaluated against a wide range of surface and total column observations. The final simulated products, such as
particulate matter (PM) and aerosol optical depth (AOD), generally show a significant improvement in skill scores compared to results obtained
with cycle 45R1. Similarly, the simulated surface concentration of sulfate, organic matter and sea salt aerosol are improved by cycle 47R1 compared to cycle 45R1. Some biases persist, such as the surface concentrations of nitrate and organic matter being simulated too high. The new wet and dry
deposition schemes that have been implemented into cycle 47R1 have a mostly positive impact on simulated AOD, PM and speciated aerosol surface
concentration.
Tree migration in the dynamic, global vegetation model LPJ-GM 1.1: efficient uncertainty assessment and improved dispersal kernels of European trees
Authors: Zani Deborah , Lehsten Veiko , Lischke Heike
Published: June 2022

Abstract. The prediction of species geographic redistribution under
climate change (i.e. range shifts) has been addressed by both experimental
and modelling approaches and can be used to inform efficient policy measures
on the functioning and services of future ecosystems. Dynamic global
vegetation models (DGVMs) are considered state-of-the art tools to
understand and quantify the spatio-temporal dynamics of ecosystems at large
scales and their response to changing environments. They can explicitly
include local vegetation dynamics relevant to migration (establishment,
growth, seed (propagule) production), species-specific dispersal abilities
and the competitive interactions with other species in the new environment.
However, the inclusion of more detailed mechanistic formulations of range
shift processes may also widen the overall uncertainty of the model. Thus, a
quantification of these uncertainties is needed to evaluate and improve our
confidence in the model predictions. In this study, we present an efficient
assessment of parameter and model uncertainties combining low-cost analyses
in successive steps: local sensitivity analysis, exploration of the
performance landscape at extreme parameter values, and inclusion of relevant
ecological processes in the model structure. This approach was tested on the
newly implemented migration module of the state-of-the-art DGVM LPJ-GM,
focusing on European forests. Estimates of post-glacial migration rates
obtained from pollen and macrofossil records of dominant European tree taxa
were used to test the model performance. The results indicate higher
sensitivity of migration rates to parameters associated with the dispersal
kernel (dispersal distances and kernel shape) compared to plant traits
(germination rate and maximum fecundity) and highlight the importance of
representing rare long-distance dispersal events via fat-tailed kernels.
Overall, the successful parametrization and model selection of LPJ-GM will
allow plant migration to be simulated with a more mechanistic approach at larger
spatial and temporal scales, thus improving our efforts to understand past
vegetation dynamics and predict future range shifts in a context of global
change.
Coupling a large-scale hydrological model (CWatM) with a high-resolution groundwater flow model to assess the impact of irrigation at regional scale

Published: June 2022

Abstract. In the context of changing climate and increasing water demand, large-scale hydrological models are helpful for understanding and projecting future water resources across scales. Groundwater is a critical freshwater resource and strongly controls river flow throughout the year. It is also essential for ecosystems and contributes to evapotranspiration, resulting in climate feedback. However, groundwater systems worldwide are quite diverse, including thick multi-layer aquifers and thin heterogeneous aquifers. Recently, efforts have been made to improve the representation of groundwater systems in large-scale hydrological models. The evaluation of the accuracy of these model outputs is challenging because: (1) they are applied at much coarser resolutions than hillslope scale, (2) they simplify geological structures generally known at local scale, and (3) they do not adequately include local water management practices (mainly groundwater pumping). Here, we apply a large-scale hydrological model (CWatM), coupled with the groundwater flow model MODFLOW, in two different climatic, geological, and socioeconomic regions, the Seewinkel area (Austria) and the Bhima basin (India). The coupled model enables simulation of the impact of the water table on groundwater-soils and groundwater-rivers exchanges, groundwater recharge through leaking canals, and groundwater pumping. This regional scale analysis enables assessment of the model’s ability to simulate water tables at fine spatial resolutions (1 km for CWatM, 100–250 m for MODFLOW) and when groundwater pumping is well estimated. Evaluating large-scale models remains challenging, but the results show that the reproduction of (1) average water table fluctuations and (2) water table depths without bias can be a benchmark objective of such models. We found that subgrid resolution (river incision) is the main factor that affects water table depth bias, while pumping affects time fluctuations. Finally, we use the model to assess the impact of groundwater-based irrigation pumping on evapotranspiration, groundwater recharge, and water table observations from boreholes.
Roundness error evaluation in image domain based on an improved bee colony algorithm
Authors: Jiang Benchi , Du Xin , Bian Shilei , Wu Lulu
Published: June 2022

Abstract. The roundness error is the main geometric characteristic parameter of shaft and hole parts. Evaluation accuracy is an important indicator of the quality inspection technology. Existing roundness error evaluation methods are insufficient in terms of the calculation amount, convergence speed, and calculation accuracy. This study proposes a novel roundness error evaluation method based on improved bee colony algorithm to evaluate the roundness error of shaft and hole parts. Population initialization and search mechanism were considered for the optimal design to improve the convergence precision of the algorithm. The population was initialized in the local search domain defined by the contour data. The roughness error was obtained by the convergence solution of the circle center calculated iteratively by the step-decreasing method. The roundness error was also evaluated by taking the same set of image domain data as an example to verify the feasibility of the proposed method. The algorithm exhibited higher accuracy than that traditional methods and thus can be widely used to evaluate the roundness error of shaft and hole parts.
Different drought types and the spatial variability in their hazard, impact, and propagation characteristics
Authors: Tijdeman Erik , Blauhut Veit , Stoelzle Michael , Menzel Lucas , Stahl Kerstin
Published: June 2022

Abstract. Droughts often have a severe impact on the environment, society, and the economy. The variables and scales that are relevant to understand the impact of drought motivated this study, which compared hazard and propagation characteristics, as well as impacts, of major droughts between 1990 and 2019 in southwestern Germany. We bring together high-resolution datasets of air temperature, precipitation, soil moisture simulations, and streamflow and groundwater level observations, as well as text-based information on drought impacts. Various drought characteristics were derived from the hydrometeorological and drought impact time series and compared across variables and spatial scales. Results revealed different drought types sharing similar hazard and impact characteristics. The most severe drought type identified is an intense multi-seasonal drought type peaking in summer, i.e., the events in 2003, 2015, and 2018. This drought type appeared in all domains of the hydrological cycle and coincided with high air temperatures, causing a high number of and variability in drought impacts. The regional average drought signals of this drought type exhibit typical drought propagation characteristics such as a time lag between meteorological and hydrological drought, whereas propagation characteristics of local drought signals are variable in space. This spatial variability in drought hazard increased when droughts propagated through the hydrological cycle, causing distinct differences among variables, as well as regional average and local drought information. Accordingly, single variable or regional average drought information is not sufficient to fully explain the variety of drought impacts that occurred, supporting the conclusion that in regions as diverse as the case study presented here, large-scale drought monitoring needs to be complemented by local drought information to assess the multifaceted impact of drought.
Unravelling the long-term, locally heterogenous response of Greenland glaciers observed in archival photography

Published: June 2022

Abstract. We present an approach for extracting quantifiable information from archival aerial photographs to extend the temporal record of change over a region of the central eastern Greenland Ice Sheet. The photographs we use were gathered in the 1930s as part of a surveying expedition, and so they were not acquired with photogrammetric analysis in mind. Nevertheless, we are able to make opportunistic use of this imagery, as well as additional, novel datasets, to explore changes at ice margins well before the advent of conventional satellite technology. The insights that a longer record of ice margin change bring is crucial for improving our understanding of how glaciers are responding to the changing climate. In addition, our work focuses on a series of relatively small and little studied outlet glaciers from the eastern margin of the ice sheet. We show that whilst air and sea surface temperatures are important controls on the rates at which these ice masses change, there is also significant heterogeneity in their responses, with non-climatic controls (such as the role of bathymetry in front of calving margins) being extremely important. In general, there is often a tendency to focus either on changes of the Greenland Ice Sheet as a whole, or on regional variations. Here, we suggest that even this approach masks important variability, and full understanding of the behaviour and response of the ice sheet requires us to consider changes that are taking place at the scale of individual glaciers.

Abstract. Deglaciation of the northwestern Laurentide Ice Sheet in the central Mackenzie Valley opened the northern portion of the deglacial Ice-Free Corridor between the Laurentide and Cordilleran ice sheets and a drainage route to the Arctic Ocean. In addition, ice-sheet saddle collapse in this section of the Laurentide Ice Sheet has been implicated as a mechanism for delivering substantial freshwater influx into the Arctic Ocean on centennial timescales. However, there is little empirical data to constrain the deglaciation chronology in the central Mackenzie Valley where the northern slopes of the ice saddle were located. Here, we present 30 new 10Be cosmogenic nuclide exposure dates across six sites, including two elevation transects, which constrain the timing and rate of thinning of the Laurentide Ice Sheet from the area. Our new 10Be dates indicate that the initial deglaciation of the eastern summits of the central Mackenzie Mountains began at ~15.8 ka (17.1 – 14.6 ka), ~1,000 years earlier than previous reconstructions. The main phase of ice-saddle collapse occurred between ~14.9 and 13.2 ka, consistent with numerical modelling simulations, placing this event within the Bølling–Allerød interval (14.6 – 12.9 ka). Our new dates require a revision of ice margin retreat dynamics, with ice retreating more easterly rather than southward along the Mackenzie Valley. In addition, we quantify a total sea-level rise contribution from the Cordilleran-Laurentide ice saddle region of ~11.2 m between 16 ka and 13 ka.

The Architectural and Topographical views of Seville in the 1838 and 1864 sketchbooks of John Gardner Wilkinson (1797–1875)
Authors: Sorowka Martin P.
Published: June 2022

The Egyptologist John Gardner Wilkinson travelled extensively throughout Europe from 1817 to 1864 and yet little has been written about his travels other than those in Egypt. Neither has there been an analysis of his notebooks and sketchbooks in which he kept a visual and written record of these travels, potentially providing a rich seam for the historian to mine. His ability to draw architecture and topography can be appreciated in his many and varied drawings of Spain, which appear in these sketchbooks on five occasions between 1818, on his second venture abroad, and 1864 on his last. This paper evaluates the truthfulness of representation of a series of architectural and topographical views of Seville and its environs in 1838 and 1864, and it is discovered that in many instances they provide invaluable visual evidence of the appearance of lost or altered buildings and landscapes. Since these drawings are as yet unpublished, this present study makes a significant contribution both to the understanding of Wilkinson as a traveller in Spain, and to the nineteenth-century visual account of the architecture of Seville.

The article presents a comparative analysis of the results of the state policy in the field of multicultural education in Canada under the title "Canadian Cultural Mosaic" and "unity of the people of Kazakhstan" in Kazakhstan today. Canada is a constitutional monarchy that occupies the second largest land area in the world in North America, with parallel English and French languages, technologically and industrially developed, multicultural and corresponding multinational parliamentary system. Kazakhstan is a multicultural multinational democratic, secular, unitary, constitutional republic, developing technologically and industrially, with parallel Kazakh and Russian languages, occupying the ninth place in the world by land area in the center of Eurasia. Canada and Kazakhstan on the world stage today have a similar multi-ethnic appearance, but their political and philosophical structure is divided into two parts. Both States create favorable conditions for the unhindered happy existence of ethnic groups devoted to their historical destiny, the preservation and improvement of the characteristics of their nation. These actions of theirs serve as an ideological approach and serve as an example for other States. It is obvious that in the case when the assimilation of nations does not occur naturally, there is a loss of the culture of ethnic groups that make up the minority, an aggravation of racism and, accordingly, the process of loss of national identity.

Introduction. Surface electromyography has proven to be a useful instrument for the assessment of success rate for different dental treatments. However, due to numerous variables that may influence the data like age, gender, fat tissue thickness etc. it is necessary to adjust the obtained values to a reference group with the same parameters. Material and methods. A number of 33 patients were included in the study (21 women and 12 men) aged between 43-67 years old (mean 54± SD1.26). Surface electromyography of masticatory muscles was used in these patients to assess the average value in a time span and overlapping coefficients. Totally 10 parameters from each patient were recorded: TAL, TAR, MML, MMR, PocTA, PocMM, BAR, Asym, TORS, Impact. Data were stored in an Excel spreadsheet and then analyzed statistically using RStudio software. Results. Based on the results of our study, the main EMG activity indices in middle-aged Moldavian individuals had the following values: for the left temporalis (TAL) was 42 µV, median 18.8 with a minimum of 3.8 and a maximum of 190 µV. For the right temporalis (TAR) the mean was 51.4 µV, median – 32.9, a minimal value of 7.9 and a maximum of 248 µV. The left masseter had a mean of 48.7 µV, median 12.3, a minimal value of 1.5 and a maximum value of 439 µV. The right masseter had a mean of 42.1 µV, a median of 16.3, minimum value 11.4 and maximum 243 µV. The overlapping coefficients deviated with 20.5% from the normal range provided by the manufacturer. Conclusions. Electromyographic activity of masticatory muscles in healthy patients can be used for comparison with patients that had various dental treatment but have the same age, gender, ethnicity, etc. The overlapping coefficients did not perfectly match in the normal range provided by manufacturer even if these subjects had previously minimum dental procedures.

Published: June 2022

Abnormal data detection is an important step to ensure the accuracy and reliability of node data in wireless sensor networks. In this paper, a data classification method based on convolutional neural network is proposed to solve the problem of data anomaly detection in wireless sensor networks. First, Normal data and abnormal data generated after injection fault are normalized and mapped to gray image as input data of the convolutional neural network. Then, based on the classical convolution neural network, three new convolutional neural network models are designed by designing the parameters of the convolutional layer and the fully connected layer. This model solves the problem that the performance of traditional detection algorithm is easily affected by relevant threshold through self-learning data characteristics of convolution layer. The experimental results show that this method has better detection performance and higher reliability.

Published: June 2022

The present study has been undertaken to evaluate In-vivo Anti–hyperglycemic and anti–oxidant activities of ethanolic Lantana camara leaves extract (LCE). The extract was prepared by cold percolation process. Phytochemical screening indicates that the presence of flavanoids, phenols, carbohydrates etc. The Anti-hyperglycemic activity of the extract was studied by In-vivo using Streptozotocin induced diabetes rat models. Glibenclamide was used as a standard drug to compare the blood glucose level. The groups treated with Lantana camara leaves extract at dose 200 and 400 mg/kg prevented the diabetes condition in a dose related manner. LCE and Glibenclamide treated rats showed decreased LPO that is associated with increased activity of SOD and catalase. The increase in the level of lipid peroxides in plasma generally is thought to be the consequence of increased production of and liberation in to the circulation of tissue lipid peroxides due to pathological changes. This action shows the Anti-peroxidative effect of LCE. The results obtained thus suggest that 50% ethanolic Lantana camara leaves extract possesses potent Anti-hyperglycemic and Anti-oxidant activity.
The economic potentialities of cactus pear as food and forage crop for sustainable agriculture in the arid and semi-arid regions: A review
Authors: Mohamed Arba
Published: June 2022

The adaptation of cactus pear to arid environments and its importance in animal and human feed make the species largely used in the arid and semi-arid regions. The economic potentialities of cactus pear as food and forage crop and its production in animal and human feed are higher. Cactus pear products and by-products and the production sustainability of cactus pear in the arid and semi-arid areas open a great number of opportunities and hopes to rural populations of these regions. These products and by-products constitute a source of income for low income of rural populations. The nutritional value of cactus pear products and their content in minerals and vitamins make cactus pear fruits and cladodes important in the animal and human feed in the arid and semi-arid areas. Medicinal and cosmetic by-products are also obtained from cactus pear products. They increase the economic income of the farmers and rural populations. Cactus pear is also an important forage for livestock in the arid and semi-arid regions thanks to its high biomass production and palatability. Cactus pear pads are consumed by all the types of livestock. They are rich in water and carbohydrates and their digestibility is high, but their content in crude proteins is low. Cactus pear could be a supplement for low quality fodder such as straw, and the combination of the two elements could be an alternative fodder for the animals of the arid and semi-arid regions.

This study was aimed to determine the residual organochlorine presence in some staple foods; Yam (Dioscorea spp) and Bambara nut (Vigna subterranean) sold in Wukari markets. Samples were randomly collected from three major markets across the study areas. Representative samples were cleansed, dried, pulverized and sieved. Extractions were determined using standard analytical techniques while residual organochlorine pesticides were determined using GCMS. The detected organochlorine pesticide residues in yam were Dichlorodiphenyltrichloroethane (DDT), heptachlor, dieldrin, toxaphene and Dichlorodiphenyldichloroethane (DDE) while those detected in Bambara nut were 1, 4dichlorobenzene, methoxychlor, pentachlorophenol, DDT, and toxaphene. This preliminary assessment showed that Yam and Bambara nut consumed in Wukari contained certain level of organochlorine pesticide residues which may be detrimental to human health in the nearest future.

Published: June 2022

Introduction: Clozapine is an atypical anti-psychotic drug widely used in the treatment of schizophrenia. It reduces suicidal ideations in schizophrenics and hence the mortality. Agranulocytosis is one among the most known serious complication of this drug. However, it can also cause life-threatening complications like necrotizing enterocolitis.

Case Report: We report a case of a 31-year-old male with past history of schizophrenia and seizure disorder on 300 mg clozapine and phenytoin 300 mg daily for 10 years. He was admitted for the evaluation of altered sensorium. Blood routine investigations and radioimaging were normal. Electroencephalogram (EEG) showed non-convulsive status epilepticus which was managed with anti-epileptic drugs. His sensorium did not improve. He started to develop fever and loose stools, later developed abdominal distension and pain. On evaluation it was found to have ischemic colitis with secondary bacterial peritonitis. Clozapine was stopped, managed conservatively. The patient recovered completely.

Conclusion: Clozapine can cause seizures. The anti-cholinergic effect of this drug can induce focal intestinal necrosis, which when unrecognized progress to transmural ischemia and perforation. Such cases need surgical intervention and is associated with high mortality. A high index of suspicion for early diagnosis, prompt correction of risk factors and early intervention prevents mortality.

The present study was aimed to the biosynthesis of Zinc oxide nanoparticles using leaf extract of Lavandula angustifolia. The nanoparticles were characterized by different techniques like UV-Visible spectroscopy, FESEM analysis, and X-ray diffraction. From the UV-Visible spectra analysis, it was observed the peak obtained at 350 nm confirmed the biosynthesis of LA-ZnONPs. The shape and size of LA-ZnONPs were confirmed by FESEM analysis, and from FESEM analysis it was found that the LA-ZnONPs were truncated and triangular in shape with an average size of 61.52 nm respectively. Further, the XRD analysis showed the LA-ZnONPs were crystalline in nature. By using well diffusion assay, the antibacterial activity of LA-ZnONPs was investigated against gram-positive S. aureus (ATCC 25923) and gram-negative E. coli (ATCC 11229) pathogens in a dose-dependent manner. The LA-ZnONPs exhibited excellent antibacterial activity against both the pathogens. The LA-ZnONPs thus possessed excellent antibacterial activity against human pathogens and can be used in drug development
