Study on The Error Structure of Radar Reflectivity Using The Symmetric Rainrate Predictor
Authors: Huyan Lidou , Gao Yudong , Wu Zheng , Liu Bojun
Published: June 2023

Abstract. Given that the Gaussianity of observation error distribution is the fundamental principle of most current modern data assimilation methods, the error structure of radar reflectivity becomes increasingly important with the development of reflectivity assimilation in convection-allowing numerical weather prediction. This study examines the error distribution of radar reflectivity and discusses what give rise to the non-Gaussian error distribution by using 6 month reflectivity departures between observations and simulations in the Southwest China. By following the symmetric error model in all-sky satellite radiance assimilation, we unveil the error structure of radar reflectivity as a function of symmetric rainrates, which is the average of observed and simulated rainrates. Unlike satellite radiance, the reflectivity error shows a sharper slope in light precipitations than moderate precipitations. Thus, a three-piecewise fitting function is more suitable for radar reflectivity than a two-piecewise fitting function. The probability distribution functions of reflectivity departures normalized by symmetric rainrates become more Gaussian in comparison with the raw probability distribution function. Moreover, the possibility of using third-party predictor to construct the symmetric error model are also discussed in this study. According to the Jensen-Shannon divergence, a more linear predictor, the logarithmic transformation of rainrate, can provide the most Gaussian error distribution.
Relationships between greenhouse gas production and landscape position during short-term permafrost thaw under anaerobic conditions in the Lena Delta
Authors: Laurent Mélissa , Fuchs Matthias , Herbst Tanja , Runge Alexandra , Liebner Susanne , Treat Claire C.
Published: June 2023

Abstract. Soils in the permafrost region have acted as carbon sinks
for thousands of years. As a result of global warming, permafrost soils are
thawing and will potentially release greenhouse gases (GHGs) such as methane
(CH4) and carbon dioxide (CO2). However, small-scale spatial
heterogeneities of GHG production have been neglected in previous incubation
studies. Here, we used an anaerobic incubation experiment to simulate
permafrost thaw along a transect from upland Yedoma to the floodplain on
Kurungnakh Island. Potential CO2 and CH4 production was measured
during incubation of the active layer and permafrost soils at 4
and 20 ∘C, first for 60 d (approximate length of the growing
season) and then continuing for 1 year. An assessment of methanogen
abundance was performed in parallel for the first 60 d. Yedoma samples
from upland and slope cores remained in a lag phase during the growing
season simulation, while those located in the floodplain showed high
production of CH4 (6.5×103 µg CH4-C g−1 C) and
CO2 (6.9×103 µg CO2-C g−1 C) at 20 ∘C. The
Yedoma samples from the permafrost layer started producing CH4 after
6 months of incubation. We conclude that landscape position is a key
factor triggering CH4 production during the growing season time on
Kurungnakh Island.
Does stream remediation reduce phosphorus and sediment exports from agricultural catchments?
Authors: Hallberg Lukas , Djodjic Faruk , Bieroza Magdalena
Published: June 2023

Abstract. Agricultural headwater streams are important pathways for diffuse sediment and nutrient losses, requiring mitigation strategies beyond in-field measures to intercept the transport of pollutants to downstream freshwater resources. As such, floodplains can be constructed along existing agricultural streams and ditches to improve fluvial stability and promote deposition of sediments and particulate phosphorus. In this study, we evaluated 10 remediated agricultural streams in Sweden for their capacity to reduce sediment and particulate phosphorus export and investigated the interplay between fluvial processes and phosphorus dynamics. Remediated streams with different floodplain designs (either on one side or both sides of channel, with different width and elevation) were paired with upstream trapezoidal channels as controls. We used sedimentation plates to determine seasonal patterns in sediment deposition on channel beds and floodplains and monthly water quality monitoring. This was combined with continuous flow discharge measurements to examine suspended sediment and particulate phosphorus dynamics and reduction along reaches. Remediated streams with floodplains on both sides of the channel reduced particulate phosphorus concentrations and loads (-54 μg L-1, -0.21 kg ha-1 yr-1) along reaches, whereas increases occurred along streams with one-sided floodplains (27 μg L-1, 0.09 kg ha-1 yr-1) and control streams (46.6 μg L-1). Sediment deposition in remediated streams was five times higher on channel beds compared to floodplains and there was no evident lateral distribution of sediments from channel to floodplains. There was no effect from sediment deposition on particulate phosphorus reduction, suggesting that bank stabilization was the key determinant for phosphorus mitigation in remediated streams, which can be realized with two-sided but not one-sided floodplains. Further, the overall narrow floodplain widths likely restricted reach-scale sediment deposition and its impact on P reductions. To fully understand remediated streams’ potential for reductions in both nitrogen and different phosphorus species and avoid pollution swapping effects, there is a need to further investigate how floodplain design can be optimized to achieve a holistic solution towards improved stream water quality.
Evaluation and optimisation of the soil carbon turnover routine in the MONICA model (version 3.3.1)
Authors: Aiteew Konstantin , Rouhiainen Jarno , Nendel Claas , Dechow Rene
Published: June 2023

Abstract. Simulation models are tools commonly used to predict changes in soil carbon stocks. Prior validation is essential, however, for determining the reliability and applicability of model results. In this study, the process-based biogeochemical model MONICA (Model of Nitrogen and Carbon dynamics on Agro-ecosystems) was evaluated with respect to soil organic carbon (SOC) using long-term monitoring data from 46 German agricultural sites. A revision and parameterisation of equations, encompassing crop and fertiliser-specific C contents and the abiotic factors of soil temperature, soil water and clay content, were undertaken and included in the model. The modified version was also used for a Morris elementary effects screening method, which confirmed the importance of environmental and management factors to the model’s performance. The model was then calibrated by means of Bayesian inference using the Metropolis-Hastings algorithm. The performance of the MONICA model was compared with that of five established carbon turnover models (CCB, CENTURY, C-TOOL, ICBM and RothC). The original MONICA model systematically overestimated SOC decomposition rates and produced on average a ~17 % greater mean absolute error (MAE) than the other models. The modification and calibration significantly improved its performance, reducing the MAE by ~30 %. Consequently, MONICA outperformed CENTURY, CCB and C-TOOL, and produced results comparable with ICBM and RothC. Use of the modified model allowed mostly adequate reproduction of site-specific SOC stocks, while the availability of a nitrogen, plant growth and water submodel enhanced its applicability compared with models that only describe carbon dynamics.

Sameness, Persons, and the Resurrection
Authors: Van der Bos Anita
Published: June 2023

According to Locke, scripture says nothing about the resurrection of the same body. We will be resurrected. But in what sense can resurrected Jane be the “same” as living Jane? Throughout his thinking, Locke holds that sameness of body and/or sameness of soul are not required for the resurrection of “the same Jane.” Sameness of person is required. Locke’s theory of personal identity was ground-breaking in the seventeenth and eighteenth centuries. It was provoking and resulted in a wave of critical responses. His distinction between “man” and “person” is important for his account of personal identity, but the distinction was hard for his contemporaries to understand. The correspondence between Locke and Edward Stillingfleet, for example, shows that for Stillingfleet the distinction between “man” and “person” is artificial. Having read this correspondence, Winch Holdsworth attacks Locke in a sermon in 1719 arguing that Locke denied the resurrection altogether. Catharine Trotter Cockburn tries to defend Locke in her Vindication. Despite her clear understanding of the distinctions applied by Locke, she too struggles with what to make of a person.

Published: June 2023

Industri konstruksi merupakan salah satu industri yang sedang banyak dibangun di Indonesia, hal ini terbukti dari banyaknya proyek yang berjalan, baik proyek gedung maupun jalan dan jembatan. Persaingan dalam konstruksi mengharuskan para jasa konstruksi untuk menyelesaikan proyek dalam waktu singkat dan dengan biaya yang se-efisien mungkin. Sebelum membuat anggaran biaya pada proyek, hitungan volume dari masing-masing pekerjaan yang akan dilakukan, akan dibuat dan dikemas dalam Bill of Quantity. Namun, pada kenyataannya banyak perkiraan yang dapat memperbesar hasil dari proses perhitungan Bill of Quantity tersebut sehingga tidak efisien. Oleh karena itu, seiring dengan berkembangnya teknologi di dunia konstruksi, tercipta Building Information Modeling (BIM) yang dapat memuat semua informasi didalam proyek pembangunan dalam bentuk 3 dimensi. Berdasarkan hal tersebut, penulis akan membandingkan hasil dari Bill of Quantity pada metode konvensional dengan metode Building Information Modeling (BIM) pada Gambar for Construction menggunakan perangkat lunak Autodesk Revit. Berdasarkan penelitian yang dilakukan, Bill of Quantity menggunakan metode BIM menghasilkan volume lebih tinggi 1.24% untuk beton and 1.14% untuk tulangan dari metode Konvensional. Hal tersebut disebabkan karena kurangnya ketelitian dalam perhitungan volume konvensional, sehingga volume yang dihasilkan tidak akurat.

Selenium is an integral component of vital biologically active compounds of the human body. Currently, the population of many countries is characterized by selenium deficiency. In this regard, many preparations of inorganic and organic forms of selenium have been developed. Nevertheless, it is evident that the most effective solution to the problem is to enrich the diet with bioavailable forms of selenium. Thus, this work aimed to synthesize and study the antioxidant and immunomodulatory effects of the molecular complex of selenium nanoparticles (Se NPs) and chitosan in laboratory rats with induced hyposelenosis. During the experiment with animals, we found that as a result of 70-day consumption of food with a low selenium content, rats develop an alimentary selenium deficiency state, as evidenced by a significant decrease in the content of this trace element in control group rats to 48.2 ±6.71 µg/kg versus 149.3 ±21.63 µg/kg in intact animals. Course, administration of the molecular complex Se NPs- Chitosan to rats of the experimental group, contributed to the replenishment of selenium deficiency: its concentration in the blood of animals was 96.6 ±3.57 µg/kg. Thus, in animals of the control group, there was a decrease in the total number of lymphocytes by 2.7 times, T-lymphocytes – by 1.8 times, and B-lymphocytes – by 2.3 times compared with similar data in intact animals. In the context of hyposelenosis, it is worth mentioning that there was a slight increase in the content of T-helper cells and cytotoxic T-lymphocytes. The synthesized Se NPs – Chitosan complex administration during hyposelenosis demonstrated a notable immunomodulatory effect by restoring the body's immune response indicators. Thus, the total number of lymphocytes increased by 3 times, T-lymphocytes – by 1.9 times, and B-lymphocytes – by 2 times. The number of T-helper cells and cytotoxic T-lymphocytes increased by 1.9 times compared to the group of intact animals and 1.6 times compared to selenium-deficient rats. Thus, the course introduction of the molecular complex Se NPs – Chitosan against the background of selenium deficiency was accompanied by inhibition of free radical oxidation processes, activation of the antioxidant system and restoration of the immune status of the organism of laboratory animals.

In this study we studied the production of bakery products with an accelerated production cycle using different dispersed flour and ion-ozoned water. The dough was prepared by mechanical loosening of compressed air under pressure (1.5-3 atm). The accelerated technology of bread production combined with wholemeal flour increases the independence of the bakery and reduces the production time of the finished product. The air bubbles in the cavitation process create a finer texture and more airy porous products resulting in higher-quality bread with excellent sensory and textural properties. The accelerated method eliminates yeast from the formulation and expands dietary varieties of yeast-free bread and flour confectionery products. This study used new accelerated technology to quickly intensify the colloidal and biochemical processes that occur during dough preparation. The technology made it possible to eliminate the dough fermentation and proofing process, thereby reducing the duration of the production process of bakery products, increasing labour productivity, and increasing the yield of bread. Qualitative, organoleptic, physicochemical and microbiological indicators and safety indicators evaluated the bakery products. The results showed that the quality of fine and ultrafine disperse flours met the recommended standards for baking yeast-free bakery products. According to laser diffraction data, the average particle size of flour obtained by whole grain milling was 194.9 μm (micron) for fine wheat flour, 609.4 μm for fine wheat flour and 830.0 μm for medium wheat flour. The finest flour fractions (less than 75 μm) provide higher gluten quality, resulting in a better balance of elasticity and extensibility in the dough, according to particle size studies of flours used to create bread. Thus, bakers can give their bread the desired texture. The overall quality of the bread is also affected by the flour's protein content, with the 10-11.5% range considered ideal. The addition of sourdough has improved the taste of baked goods. Bread products made from different dispersed flour and ion-ozoned water had good quality, organoleptic, physicochemical and microbiological indicators, and safety indicators. They could be stored for up to 5 days. As a result of using the accelerated method of dough preparation will improve the structural-mechanical, rheological and technological properties of bread, bakery and flour confectionery products.

Coal and coal argillites from seams I, II and III and from coal intercalations above the latter have been sampled and chemically analyzed. The contents of 28 elements detected in the coal ash and 29 in the coal argillites have been determined. The mean values of element contents in the coal ash are compared with the clarke of concentration for bituminous coal and groups of elements typomorphic of each seam were defined. Typomorphic elemens are also defined for the coal argillites of each seam by comparing the mean contents with the clarkes of concentrat ion for sedimentary rocks. The ratio bet ween the mean element contents in the coal ash and in the ash of coal argillites is used to determine the affinity of elements to organic matter. Elements bound to the organic matter are found to predominate in seams I and II whereas seam III is dominated by inorganically bound elements. Each seam is characterized by a specific distribution of the elements among the five groups defined on the basis of their affinity to organic matter. Correlation coefficients between the elements have been derived by computer processing of data. They are used to define five geochemical assemblages for each seam plotted on graphs to show the e1emenl interdependence. Both the graphs and the assemblage compositi ons show differences in each seam.

The protozoan genus Leishmania, which belongs to the Trypanosomiases family, is the source of the infectious parasitic disease leishmaniasis. Leishmaniasis is third in importance among vector-borne diseases worldwide, behind malaria and sleeping sickness. Leishmaniasis is treated with a variety of drugs, however side effects and drug resistance have been noted. There are countless opportunities to find new drugs to cure infectious diseases by researching plant remedies. Some plant medicines and natural products have a new candidate for treatment of leishmaniasis. Medicinal plants are believed to be an important source of new chemical substances with potential therapeutic effects. This review work is focused on the therapeutically active plants which are used in the treatment of leishmaniasis and have less side effects and less cost.

Job involvement has continued to receive great attention of management scholars and organisational practitioners globally. In a similar direction, this study examined psychological capital as a predictor of job involvement among secondary school teachers in North-West Senatorial District of Benue State, Nigeria. The study adopted cross-sectional survey design. Participants were 354 teachers comprising of 195(55.1%) males and 159(44.9%) females randomly sampled from 40 secondary schools. Teachers’ Job Involvement Scale (TJIS) and Psychological Capital Questionnaire were used for data collection. Results of Multiple Linear Analysis revealed that psychological capital is an important factor in predicting job involvement of secondary school teachers. Particularly, resilience is the most important component of psychological capital with positive influence on job involvement and its two dimensions. Hope and optimism are also important psychological capital components but only predict emotional and not physical job involvement. Finally, self-efficacy seems to be less important component of psychological capital with no significant independent influence on both physical and emotional job involvement dimensions. It is concluded that psychological capital enhances job involvement. Therefore, curriculum developers in teachers’ colleges should incorporate training courses targeted at developing psychological capital of teachers in order to enhance their job involvement during professional practice.

Keywords: Job involvement, psychological capital, hope, optimism, resilience, self-efficacy.
Virgin Coconut Oil: A Review
Authors: Khairati Miftahul
Published: June 2023

Virgin Coconut Oil (VCO) is coconut oil that has undergone a minimal amount of processing without the use of artificial chemicals. VCO has the greatest lauric acid level of the two oils, with 53.70-54.06%, compared to regular coconut oil of 2.81% and palm oil of 0.45%. VCO is advantageous for health due to its high lauric acid concentration, which also increases endurance and hastens the healing of sickness. Coconut, which comprises water, protein, and fat, is a key component in the production of VCO. These three substances are an emulsion in which the emulsifier is a protein. A chemical known as an emulsifier serves to thicken or stabilize the emulsion. To prevent the blending of the oil and water droplets, a thin layer of coconut fruit protein will bind the droplets of coconut oil. If the emulsion bond is compromised, oil will leak out. On a small scale, centrifugation, fermentation, and enzymatic processes can be used to dissolve the emulsion.
