Authors: Khamidov M , Ishchanov J , Khamidova Sh , Isabaev K , Altmishev A 
Published: February 2023

Abstract
The global climate changes and their influence on agriculture in Uzbekistan were analyzed, including problems of irrigation water shortage on irrigated lands in the lower reaches of the Amu Darya with the greatest water shortage due to repeated dry years. Additionally, the recommendations for the effective use of water resources in the conditions of meadow alluvial soils salinization and shallow salinized groundwater were proposed to use subirrigation and drip irrigation to irrigate cotton, maintaining the pre-irrigation soil moisture of the lowest soil moisture capacity. The introduction of a science-based regime for cotton using subirrigation and drip irrigation methods provides conservation of water up to 1.596–1.757 (subirrigation) and 1.596–1.757 (drip irrigation) cbm/ha, an increase in cotton yield of up to 6.3 centner/ha.

Published: February 2023

Abstract
This article presents the results of improving the land ameliorative condition of lands as a result of growing phytoameliorating plants as a secondary crop in conditions of water shortage. There is a scientific research aimed at saving water resources used for salt washing. White sorghum (Sorghum Vulganell pers) and mung bean (Phaselus aureus Piper) were planted as phytoameliorating crops and compared with uncultivated fields. During the experiments, when the effect of phytoameliorating crops on the number of chlorine ions contained in the soil was studied, initially, at the beginning of the vegetation period, the number of chlorine ions in the soil tillage layer (0–30 cm) increased by 0.015%. At the end of the experiments, the number of chlorine ions in the tillage layer (0–100 cm) was 0.012%. Chlorine ion content in the sorghum (Sorghum Vulganell pers) was 0.033% in the driving layer (0–30 cm) and 0.029% in the 0–100 cm layer, while chlorine ion content in the soil was 0.036 and 0.032% in the moss (Phaselus aureus Piper). In addition, the highest saline leaching rate in the experimental field was 5383 cbm/ha in the plowed field. And the seasonal salinity leaching rate was 2380 cbm/ha when sowing white corn (Sorghum Vulganell pers) as a phytoameliorant, and when sowing moss (Phaselus aureus Piper), 3403 cbm/ha. This is 37–56% less than the control or 1980–3003 cbm/ha.

Published: February 2023

Abstract
Anethum graveolens L. (Dill) is an aromatic, medicinal, and food plant that is widely known in the world. This paper presents the results of the study of the essential oil of A. graveolens, which was cultivated in the Stavropol region (Russia, North Caucasus) to restore its growth. Herb of A. graveolens, variety “Scythian”, was collected in different fields of the limited company “Cossack agriculture “Staropavlovskoe”. The essential oil was obtained by Clevenger distillation. The chemical composition of the essential oils was studied by the GC/MS method. 25 compounds were detected in essential oil: carvone; 3.9-epoxy-1-p-menthene; ipsdienol; 2-hydroxycineol; allyl caprate; carveol; 6-camphenol; 5-isopropenyl-2-methyl-7-oxabicyclo [4.1.0] heptane-2-ol; piperitone oxide; 3-methyl-2-pent-2-enyl-cyclopent-2-enone; cis-p-mentha-2.8-dien-1-ol; 2-cyclol piperitone oxidehydroxy-3-methyl-6-(1- methyleth); limonene-6-ol, pivalate; isopulegol acetate; z-(13,14-epoxy) tetradec-11-en-1-ol acetate. The major component in the oil detected was arvone (36.9–44.5%). The obtained data confirmed the positive result of the cultivation of A.graveolens with the content of carvone in the essential oil of herbs comparable to the content of carvone in fruits.
A study of the effect of mineral fertilizers as a factor in improving environmental safety and productivity of crop rotation
Authors: Shikhova O A , Chukhina O S , Demidova A I 
Published: February 2023

Abstract
The crop rotation productivity depends on the crops and chemicals used, especially fertilizers. Cultivation of crops makes it possible to obtain environmentally safe products due to biologically correctly selected predecessors and with the correct alternation of crops in space and time. This allows for savings in plant protection products and differentiated use of fertilizers. Based on the results of 28-year research into the yield and productivity of crop rotation with the use of various doses of fertilizers, the regularities of changes in the content of mobile phosphorus and exchangeable potassium in the soddy-podzolic medium loamy soil of Vologda Oblast were revealed, and regression models that reflect their relationship with the productivity of crop rotation were built. The results made it possible to build a non-linear regression model that reflects quantitative features of the dependence of crop rotation productivity on the levels of mobile phosphorus and exchangeable potassium. With an increase in the content of mobile elements in the soil in the case of mobile phosphorus, the productivity of crop rotation will increase with a slight slowdown with each single dose, and in the case of exchangeable potassium it will increase evenly.
Determination of the significance of quality criteria and functional limitations affecting the effectiveness of robotization of mobile energy means in crop production
Authors: Godzhaev Z A , Senkevich S E , Zubina V A , Godzhaev T Z 
Published: February 2023

Abstract
To assess the effectiveness of the robotization of mobile energy means (RMES), it is necessary to consider many quality criteria and functional limitations that characterize the work of RMES (operational, economic, functional, etc.). The formation of quality criteria allows us to justify the effectiveness of the robotization of MES, the improvement of the multi-criteria optimization apparatus and the software package for performing optimization calculations considering the aspect of robotization of mobile power facilities for agricultural purposes in crop production. However, unfortunately, most of the quality criteria cannot be formalized, that is, it is not always possible to establish mathematical dependencies of these quality criteria on variable parameters. In this regard, the purpose of these studies is to solve the problem of assessing the weight of each quality criterion and functional limitations, including using expert methods
Line-encoded structured light measurement method in measuring shiny and transparent objects

Published: February 2023

Abstract
Structured light measurement (SLM) has been widely used in acquiring the three-dimensional (3D) shape of objects because of its high precision and high speed. However, the intensity based structured light coding strategies like sinusoidal patterns is difficult to measure transparent and shiny objects with high dynamic range surface reflectance due to inaccurate light intensity information. Divergent multi-line structured light projection and traditional gray-code method avoids this problem by extracting lines. However, traditional gray-code method requires additional many patterns to distinguish the order of lines, which reduces the measurement efficiency. To overcome defects, this paper proposes a line-encoded few-pattern SLM method in measuring shiny and transparent objects. In this method, we simultaneously extract the edge line, the center line and obtain their orders by projecting only five patterns. Many experiments were implemented to prove its accuracy and robustness. Because only five patterns are required, the proposed method greatly accelerate the process of reconstruction, which is indispensable for 3D real-time reconstruction. We conducted a dental model dynamic scanning experiment to prove it.

Published: February 2023

Abstract
Interfacial intermetallic compound (IMC) layer is critical during realizing the galvanic corrosion mechanism and strength degradation of aluminium/steel resistance spot welding (RSW) joints. The effect of IMC layer on the corrosion behaviour of RSW joint between 5182 aluminium alloy and galvanized DP780 dual-phase steel was investigated by immersion corrosion method and electrochemical method. Results demonstrated localized corrosion around Fe-rich phase particles on aluminium nugget and preferential corrosion at the interface front near IMC layer. The IMC layer had the highest open circuit potential value of −0.569 V and low corrosion current density among the investigated nugget and substrates. The potential difference (0.184 V) between the cathodic IMC layer and large area of anodic aluminium nugget was responsible for the preferential initiation of localized corrosion at the interface front near the IMC layer.
The Role of Uncertainty in Professionals’ Thinking about Children Who Harm Other People
Authors: Heron Gavin , Black Kate 
Published: February 2023

Abstract
Uncertainty in thinking and reasoning is crucial in allowing professionals to engage with the complexities of practice, yet the way it is expressed in childcare social work remains under-researched. This study examines the uncertainty expressed by professionals when discussing children who present a serious threat of harm to others. Discourse analysis is used to examine data from twenty meetings involving seventy-five professionals. The findings suggest that there is considerable variance in the way professionals express uncertainty and in many of the meetings it appears to be relatively infrequent. The low levels of expression of uncertainty in such complex cases are problematic because it reflects limitations in professionals’ thinking and actions. The majority of instances of uncertainty occur in response to a question from another professional. This is a positive aspect of professional interaction and suggests that robust questioning from peers that encourage analysis of our practice might be particularly useful in prompting uncertainty. Rather than ignore or supress uncertainty by viewing it in negative terms, it should be valued and embraced by professionals who want to reduce unnecessary errors and enhance children’s safety.

Abstract
Malaria is responsible for over 435,000 deaths annually, mostly occurring in sub-Saharan Africa. Detecting Plasmodium spp. sporozoites (spzs) in the salivary glands of Anopheles (Diptera: Culicidae) vectors with circumsporozoite enzyme-linked immunosorbent assay (csELISA) is an important surveillance method. However, current technological advances are intellectual property and often require of distribution and highly trained users. The transition into paper-based rapid plataforms would allow for decentralization of survillance, especially in areas where it was virtually eliminated. The addition of bio-based materials have shown the potential to improve binding of target antigens, while being widely available. Here, we evaluate the use of chitosan and cellulose nanocrystals (CNC) as antibody carriers and substrate coatings on 96-well plates and on wax hydrophobized paper plates for the detection of Plasmodium falciparum (Pf), P. vivax VK210 (Pv210), and P. vivax VK247 (Pv247). To further improve the user-friendliness of the paper plates a quantitative photograph image-based color analysis was done. Interactions between the materials and the assay antibodies were studied by quartz crystal microbalance with dissipation monitoring (QCM-D). Overall, the addition of chitosan increased the interaction with antibodies and enhanced signaling in all tests. This work demonstrated that the adaptation of a PcsELISA shows potential as a cost-effective alternative assay platform easily adaptable in deployable testing sites that also showed reduction in reagent volumes by 80% and assay run time by seventh. While dipstick assays were previously developed, paper-based assays are a cost-effective and field-deployable alternative, reducing volumes of reagents that could be used in malaria control and elimination settings.
The Impact of Diet and Photoperiodism on the Life History ofThanatophilus sinuatus(Coleoptera: Silphidae)

Published: February 2023

AbstractThe forensically important genus Thanatophilus Leach, 1815 (Coleoptera: Silphidae) is a widespread group of carrion beetles that occupies the Holarctic and Afrotropical realms. It has recently received more recognition, as its species are frequently detected on large carrion, including humans, and can be useful in estimating the time of colonization (TOC) and the post-mortem interval (PMI). The immature stages of Thanatophilus sinuatus (Fabricius, 1775) were reared on three different meat diets (pork liver, pork muscle, and chicken muscle). Diet influence on some of the essential life history traits of the species was examined for different populations. Our findings indicated an accelerated development on pork muscle followed closely by pork liver and a prolonged development on chicken muscle. The diet significantly affected the size, and the body condition (weight/ size) as both pork muscle and liver produced individuals in better physical condition (larger and heavier). The impact of two cyclic photoperiod regimes (16 h Light (L): 8 h Dark (D) and 12 h L: 12 h D) was further evaluated and indicated no significant variability.
The communicative constitution of atomization: online prepper communities and the crisis of collective action

Published: February 2023

AbstractAs environmental and societal crises increase in numbers, severity, and urgency, online forums for so-called “doomsday preppers” have seen a concomitant surge in membership. Beginning from the perspective of communicative constitution of organization, we explore the sociotechnical communities that emerge on such forums. Methodologically, we use netnographic observations to show that online prepper communities are organizational, in the sense of being networks of communicative episodes that use common narratives to build identities around material objects and physical practices. However, the online prepper communities do not move from the enactment of organization to acting as organizations. This observation leads us to conceptualize online prepper communities as atomizations whose communicative constitution does not entail a capacity for collective action, but only manifests the similarity of disparate individuals. The communicative constitution of atomization, we argue, is symptomatic of an underlying social logic, which promotes individualized responses to collective problems.

ABSTRACT
The triggering mechanism for the most luminous, quasar-like active galactic nuclei (AGN) remains a source of debate, with some studies favouring triggering via galaxy mergers, but others finding little evidence to support this mechanism. Here, we present deep Isaac Newton Telescope/Wide Field Camera imaging observations of a complete sample of 48 optically selected type 2 quasars – the QSOFEED sample ($L_{\rm [O\, \small {III}]}\gt 10^{8.5}\, \mathrm{L}_{\odot }$; z &lt; 0.14). Based on visual inspection by eight classifiers, we find clear evidence that galaxy interactions are the dominant triggering mechanism for quasar activity in the local universe, with 65$^{+6}_{-7}$ per cent of the type 2 quasar hosts showing morphological features consistent with galaxy mergers or encounters, compared with only 22$^{+5}_{-4}$ per cent of a stellar-mass- and redshift-matched comparison sample of non-AGN galaxies – a 5σ difference. The type 2 quasar hosts are a factor of 3.0$^{+0.5}_{-0.8}$ more likely to be morphologically disturbed than their matched non-AGN counterparts, similar to our previous results for powerful 3CR radio AGN of comparable [O iii] emission-line luminosity and redshift. In contrast to the idea that quasars are triggered at the peaks of galaxy mergers as the two nuclei coalesce, and only become visible post-coalescence, the majority of morphologically disturbed type 2 quasar sources in our sample are observed in the pre-coalescence phase (61$^{+8}_{-9}$ per cent). We argue that much of the apparent ambiguity that surrounds observational results in this field is a result of differences in the surface brightness depths of the observations, combined with the effects of cosmological surface brightness dimming.
Modelling the energy distribution in CHIME/FRB catalogue-1
Authors: Bhattacharyya Siddhartha , Bharadwaj Somnath , Tiwari Himanshu , Majumdar Suman 
Published: February 2023

ABSTRACT
We characterize the intrinsic properties of any FRB using its redshift z , spectral index α and energy E33 in units of $10^{33} \, {\rm J}$ emitted across 2128–2848 MHz in the FRB’s rest frame. Provided that z is inferred from the measured extra-galactic dispersion measure DMEx, the fluence F of the observed event defines a track in (α, E33) space which we refer to as the ’energy track’. Here, we consider the energy tracks for a sample of 254 non-repeating low dispersion measure FRBs from the CHIME/FRB catalogue-1, and use these to determine the conditional energy distribution, n(E33∣α), i.e. the number of FRBs in the interval ΔE33 given a value of α. For all values of α, we can identify two distinct energy ranges indicating that there are possibly two distinct FRB populations. At high energies, the distribution is well fitted by a modified Schechter function whose slope and characteristic energy both increase with α. At low energies, the number of FRBs are in excess of the predictions of the modified Schechter function indicating that we may have a distinctly different population of low-energy FRBs. We have checked that our main findings are reasonably robust to the assumptions regarding the Galactic Halo and Host galaxy contributions to the dispersion measure.
Dynamical data mining captures disc–halo couplings that structure galaxies
Authors: Johnson Alexander C , Petersen Michael S , Johnston Kathryn V , Weinberg Martin D 
Published: February 2023

ABSTRACTStudying coupling between different galactic components is a challenging problem in galactic dynamics. Using basis function expansions (BFEs) and multichannel singular spectrum analysis (mSSA) as a means of dynamical data mining, we discover evidence for two multicomponent disc–halo dipole modes in a Milky-Way-like simulated galaxy. One of the modes grows throughout the simulation, while the other decays throughout the simulation. The multicomponent disc–halo modes are driven primarily by the halo, and have implications for the structural evolution of galaxies, including observations of lopsidedness and other non-axisymmetric structure. In our simulation, the modes create surface density features up to 10 per cent relative to the equilibrium model stellar disc. While the simulated galaxy was constructed to be in equilibrium, BFE + mSSA also uncovered evidence of persistent periodic signals incited by aphysical initial conditions disequilibrium, including rings and weak two-armed spirals, both at the 1 per cent level. The method is sensitive to distinct evolutionary features at and even below the 1 per cent level of surface density variation. The use of mSSA produced clean signals for both modes and disequilibrium, efficiently removing variance owing to estimator noise from the input BFE time series. The discovery of multicomponent halo–disc modes is strong motivation for application of BFE + mSSA to the rich zoo of dynamics of multicomponent interacting galaxies.
X-ray non-detection of PSR J0250 + 5854
Authors: Tan C M , Rigoselli M , Esposito P , Stappers B W 
Published: February 2023

ABSTRACT
We conducted a deep XMM–Newton observing campaign on the 23.5-s radio pulsar PSR J0250 + 5854 in order to better understand the connection between long-period, radio-emitting neutron stars and their high-energy-emitting counterparts. No X-ray emission was detected resulting in an upper limit in the bolometric luminosity of PSR J0250 + 5854 of &lt;1031 erg s−1 for an assumed blackbody with a temperature of 85 eV, typical of an X-ray Dim Isolated Neutron Star (XDINS). We compared the upper limit in the bolometric luminosity of PSR J0250 + 5854 with the known population of XDINSs and found that the upper limit is lower than the bolometric luminosity of all but one XDINS. We also compared PSR J0250 + 5854 with SGR 0418+5729, the magnetar with low dipole magnetic field strength, where the upper limit suggests that if PSR J0250 + 5854 has a thermal hotspot like SGR 0418 + 5729, it would have a blackbody temperature of &lt;200 eV, compared to 320 eV of the magnetar.
