Abstract
A state of the art commercial detector, a PCO Edge 4.2 bi based on a back illuminated sCMOS sensor developed for applications in the visible light/ultra violet regime has been adapted for ultra-high vacuum operations and has been characterized using soft X-ray in the energy range from 30 eV to 1000 eV. The imager features 2048 × 2048 pixel with a pixel size of 6.5 μm × 6.5 μm and allows full frame acquisitions at 48 Hz with a dynamic range of 88 dB at a noise level of 1.9 e
−. Spatial resolution and quantum efficiency have been elucidated in the aforementioned energy range at a soft X-ray beam line at Elettra Sincrotrone Trieste. The handiness of the camera as well as its Python library package allows easy and fast integration into the beam line environments of synchrotron sources and free electron lasers.

Published: January 2022

Abstract
A Monolithic Active Pixel Sensor (MAPS) is currently being designed in a new 130 nm high-resistivity (>1 kΩ·cm) CMOS process for full image beam monitoring in the carbon-ion therapeutic facility. The charge sensing node collects the charge deposited by the carbon ions that pass through the MAPS. A 3-dimensional TCAD model of the pixel has been established to study the carbon-ion induced process in the MAPS. This paper will discuss the thickness of the depletion layer, the charge collection efficiency, the charge collection time, and the characteristics of NMOS devices with different bias voltages and carbon-ion hitting locations.

Abstract
Neutrinos are particles that interact rarely, so identifying them requires large detectors which produce lots of data. Processing this data with the computing power available is becoming even more difficult as the detectors increase in size to reach their physics goals.
Liquid argon time projection chamber (LArTPC) neutrino experiments are expected to grow in the next decade to have 100 times more wires than in currently operating experiments, and modernization of LArTPC reconstruction code, including parallelization both at data- and instruction-level, will help to mitigate this challenge.
The LArTPC hit finding algorithm is used across multiple experiments through a common software framework. In this paper we discuss a parallel implementation of this algorithm. Using a standalone setup we find speedup factors of two times from vectorization and 30–100 times from multi-threading on Intel architectures. The new version has been incorporated back into the framework so that it can be used by experiments. On a serial execution, the integrated version is about 10 times faster than the previous one and, once parallelization is enabled, further speedups comparable to the standalone program are achieved.
Joint quantum–classical Hamilton variational principle in the phase space*
Authors: Zhdanov Dmitry V , Bondar Denys I 
Published: January 2022

Abstract
We show that the dynamics of a closed quantum system obeys the Hamilton variational principle. Even though quantum particles lack well-defined trajectories, their evolution in the Husimi representation can be treated as a flow of multidimensional probability fluid in the phase space. By introducing the classical counterpart of the Husimi representation in a close analogy to the Koopman–von Neumann theory, one can largely unify the formulations of classical and quantum dynamics. We prove that the motions of elementary parcels of both classical and quantum Husimi fluid obey the Hamilton variational principle, and the differences between associated action functionals stem from the differences between classical and quantum pure states. The Husimi action functionals are not unique and defined up to the Skodje flux gauge fixing (Skodje et al 1989 Phys. Rev. A 40 2894). We demonstrate that the gauge choice can dramatically alter flux trajectories. Applications of the presented theory for constructing semiclassical approximations and hybrid classical–quantum theories are discussed.

Published: January 2022

Abstract
The primary objective of this paper was to synthesize a calcium silicate (CaSiO3) and investigate the effect of CaO/SiO2 compositions on the structure formation of synthetic material. CaSiO3 was prepared through the solid-state method using CaO from chicken eggshells and commercial SiO2 powder as starting material. To investigate the effect of CaO/SiO2 on the structure of CaSiO3, the different molar ratios of CaO/SiO2 (i.e., 1:1, 1:7, 2:7, and 3:7) were used. BET results show the resulting product has a high specific surface area of 13,18 ±30.53 m2g-1 and a pore size of 15,16 ±18.4 nm obtained as mesoporous material. The obtained CaSiO3 particles, then to be applied for the degradation of dye pollutants in water. The adsorption capacity was evaluated by methylene blue (MB) and brilliant green (BG) degradation. The parameters of CaO/SiO2 mass ratio and contact time on the degradation efficiency of BG and MB were investigated, respectively. The results showed that the best model for BG adsorption onto CaSiO3 was a pseudo-first-order model, whereas the best model for MB adsorption was a pseudo-second-order model.

Abstract
The depletion of fossil fuel sources and increased CO2 emissions has triggered intensive research to discover renewable energy sources. With the Low Carbon Scenario, the role of renewable energy will increase to 58% in 2050. As a renewable energy source, bioethanol is environmentally friendly which can substitute gasoline. Currently, the third-generation bioethanol production technology from microalgae is still being developed. Chlorella vulgaris is one of the microalgae types with high carbohydrate content and is easy and fast to cultivate. This study aims to evaluate the growth rate of C. vulgaris cultivated in a bubble column photobioreactor using artificial seawater aerated with pure CO2. Two LED tube lights were used with 12 h light and 12 dark cycles for 12 - 13 days. Microalgae culture population was measured every 24 h using a Neubauer-improved counting chamber and a microscope equipped with a digital camera. The results showed that the maximum specific growth rate,/max, was found to be 0.344 d1, and the highest concentration of 1.88 x107 cells mL1 occurred on day 7. Moreover, the microalgae populations were also measured using a densitometer. Since the calculation of the cell population used secondary data from the literature, the results were less accurate than those of the counting chamber.

Published: January 2022

Abstract
Cellulose-based polymers have garnered significant attention as potential candidates for use in enhanced oil recovery (EOR). The challenge in the design of EOR polymers is the need for materials with a high low critical solution temperature (LCST) and the ability to withstand harsh environmental conditions. In this study, cellulose-methylcellulose graft copolymers were prepared with different cellulose to methylcellulose weight ratios. The copolymerization was carried out using gamma radiation doses of 5, 15, and 25 kGy, respectively. The LCST of the copolymers were evaluated using differential scanning calorimetry analysis. The effect of salt addition on the LCST of the materials was studied using different phosphate-buffered saline (PBS) concentrations. The results showed that the cellulose monomer concentration increase from 0.1 to 0.5% in 2% methylcellulose dispersed in water reduced the LCST from 59 to 54°C. The hydrophobic nature of cellulose moieties induced the aggregation of the copolymers into core-shell micelles. Besides, higher gamma radiation doses lowered the LCST of the copolymers. The increase in the salt concentration in the PBS medium tended to decrease the LCST due to disrupted hydration structure of the polymer chains. This work revealed that cellulose-methylcellulose copolymers could be used in chemical EOR due to their high phase transition temperatures, preventing pore clogging and enhancing oil production in the producing wells.
Functionalization of multi-walled carbon nanotube (MWCNT) with CTACe surfactant and polyethylene glycol as potential drug carrier

Published: January 2022

Abstract
Multi-walled Carbon Nanotube (MWCNT) pure is easy to form aggregate, making it difficult to apply as a drug carrier since it can be toxic to the body. It can be overcome by functionalization using surfactants, like cetyltrimethyl ammonium trichloro-monobromo-cerate (CTACe) and polyethylene glycol (PEG). First, MWCNT was functionalized with CTACe surfactant, then further PEG 6000 was used with several MWCNT-CTACe ratios. The functionalization was conducted under ultrasonic treatment, then followed by filtration, washing, and drying. The functionalized MWCNT underwent dispersion tests using water and dimethyl sulfoxide (DMSO) as the solvents. A dispersion test with water solvent shows that the functionalized MWCNT still forms aggregates within a few minutes. Whereas, in DMSO solvent, the functionalized MWCNT can be stabilized for more than five days without forming aggregates. FTIR results show a new peak at 1105 cm−1 and an increased peak intensity around 3432 cm−1, corresponding to C-N and hydrogen bonding of N-H vibration from the CTACe. The FTIR from PEG addition shows an increase in the wavenumbers around 3432,87 cm−1, indicating the strength of O-H/N-H intermolecular hydrogen interactions of O-H PEG with N-H surfactant ether bonds.

Abstract
Acid Mine Drainage (AMD) is a severe environmental problem that results from mining industry activities around the world. Water pollution from acid mine drainage not only damages the quality of water and soil but also affects a sustainable environment such as plants and animals in a mining area. Mining water typically has acid with highly toxic heavy metal concentrations. Remediation is one of the technologies that can be used to reduce heavy metal pollutant water from mine drainage water. There were many researches about remediation in the past, but phytoremediation has attracted various researchers’ attention. Phytoremediation is a remediation pollutants method using a plant as a media that has the advantages of being efficient, economical, and eco-friendly. The most significant important aspect for the successful phytoremediation method is a selection of the plant species. Aquatic plants have a high level of efficiency in reducing organic and inorganic pollutants in water. The efficiency of aquatic plants can be improved with innovative approaches. This review focuses on the comparison characteristic of aquatic plants in the phytoremediation method to reduce heavy metals in pollutant water. Comparison served to support innovations to improve efficiency phytoremediation application research challenge for acid mine drainage issues in the near future.

Published: January 2022

Abstract
Organic farming nowadays is becoming popular and getting high attention worldwide. This growing field needs many nutrient sources from natural resources since organic farming cannot use synthetic fertilizer. Thus, many sources of nutrient-rich solids are being used to fulfill the demand. Here, chicken feather powder, horn powder, poultry manure, and compost are used for producing organic fertilizer. These solid waste materials are blended in various compositions, i.e., horn plus poultry and horn plus compost. Selected fertilizer formulations were tested to grow barley in a pot trial inside a glasshouse using several dosages. After about four weeks old, the barley plant is harvested and weighed to determine the optimum fertilizer formula and dosage. It appears that fertilizer formula using horn and poultry is the best fertilizer that can produce the highest biomass in a respective time and compete with synthetic NPK fertilizer.

Published: January 2022

Abstract
Increasing the yield of spring barley on light chestnut soils of the Volgograd region is possible through the use of microbiological fertilizers that activate the processes of plant growth and development. The influence of the methods of basic tillage and the application of mineral and bacterial fertilizers “Azotovit” and “Phosphatovit” on the content of nitrogen in the soil was studied. The degree of decomposition of the linen cloths was the maximum for deep flat-cutting processing. According to the binary interaction, the best results were obtained on the variant with deep flat-cutting processing with double application of bacterial fertilizers. The introduction of bacterial fertilizers sharply increases the content of azotobacter, and especially when they are applied twice. The lowest toxicity of the soil in barley crops compared to the control was noted on the variant with deep flat-cutting treatment, and the maximum on the variant of dump treatment. The analysis of data on the structure of the crop also indicates the advantage of the variant of deep flat-cutting tillage with double application of microbiological fertilizers. The most cost-effective variants were with double application of bacterial fertilizers on the background of deep flat-cutting tillage.

Published: January 2022

Abstract
The problem of provision of the population with high-quality drinking water is currently one of the most topical in connection with the unsatisfactory technical condition of the existing water supply systems and pollution of the water sources. Natural zeolites, which have a sufficiently high sorption capacity, cation-exchange properties, relatively low cost and availability, are increasingly being used in recent times for water purification. The mineralogical properties of natural zeolites of the Tayzhuzgen and Shankanai deposits have been investigated. A comparative study of the sorption properties of the natural and modified zeolites of the Kazakhstan deposits has been carried out on model solutions, containing iron ions (Fe2+). The exchange mechanism and the degree of extraction of ions from the solutions have been established. The efficiency of the municipal water purification in the Auezovskiy district of Almaty with zeolites of the Shankanai field has been equal to 85.94%. This suggests a possibility of using these zeolites to purify water from iron ions with the purpose of water treatment in the dairy industry.

Abstract
In areas with a pronounced relief, water erosion causes great harm to agriculture and other sectors of the national economy. It leads to the destruction of the soil cover, a reduction in the area of arable land, a decrease in fertility, the removal of erosion products into floodplains, the siltation of ponds and rivers and the destruction of the road network. The scientific goal was to identify the influence of the main natural factors (snow reserves, freezing and soil moisture) on the formation of the spring melt water runoff on the plow. To study the questions raised, the water-balance method was used with the use of runoff sites. Observations showed that the formation of the melt water runoff depended on the depth of soil freezing. With shallow soil freezing up to 50 cm, there was no runoff. All the melt water was absorbed by the soil. As a result of 30 years of research (1991-2020), it was found that the average annual runoff on the plow was very weak - 3.8 mm on the scale of Surmach, the runoff coefficient is 0.05, shallow soil freezing - 19-28 cm, duration of snow melting - 16 days.

Abstract
Normal organization of placental structures at different stages of pregnancy is critical for the growth and development of the fetus. The aim of this study is to characterize the localization and ratio of epithelial and mesenchymal cells in the placenta of cows with physiological and complicated preeclampsia pregnancy using the immunohistochemical method. To date, it has been established that adverse environmental factors adversely affect the reproductive potential of animals regardless of their gender. The results of the study demonstrated that in the placenta of cows with the development of preeclampsia in the last stages of pregnancy, there was a significant decrease in the content of keratin filaments both in the trophoblasts of the villous tree of the fetus and in the epithelial cells of the maternal part in comparison with physiological values. In this case, the vimentin filaments also underwent partial degradation. Thus, the ratio of keratin and vimentin intermediate filaments can be used as a histological criterion for changes in the placental structures of cows during the development of preeclampsia.
