Published: May 2023

The primary objective of the water purification process is to remove harmful chemical compounds and microorganisms from water sources in order to produce water suitable for human consumption. Water purification satisfies the demand for drinkable water, which is a requirement for many industries, including the medical, pharmaceutical, and chemical industries, among others. Access to purified water is the single most important factor determining a nation’s strength and prosperity. As a consequence, researchers all over the world are investigating a wide variety of potential strategies for improving and preserving the water supply. In this paper, we present the findings of our research into a possible water strategy for purifying water and improving accessibility to drinkable water in areas prone to drought. This article presents the concepts of the complex intuitionistic fuzzy Dombi weighted averaging (CIFDWA) operator, the complex intuitionistic fuzzy Dombi ordered weighted averaging (CIFDOWA) operator, the complex intuitionistic fuzzy Dombi weighted geometric (CIFDWG) operator, and the complex intuitionistic fuzzy Dombi ordered weighted geometric (CIFDOWG) operator in complex intuitionistic fuzzy (CIF) settings. In addition, we investigate several important key features of these operators. Moreover, we introduce an improved score function to overcome the deficiencies of the existing score function under CIF knowledge. Furthermore, we effectively apply the proposed score function and newly defined operators to select the best technique for purifying water at a commercial scale. Additionally, we establish a comparative analysis to show the validity and feasibility of the proposed techniques compared to existing methods.

Precise adjustments of farm management activities, such as irrigation and soil treatment according to site-specific conditions, are crucial. With advances in smart agriculture and sensors, it is possible to reduce the cost of water and soil treatment inputs but still realize optimal yields and high-profit returns. However, achieving precise application requirements cannot be efficiently practiced with spatially disjointed information. This study assessed the potential of using an electromagnetic induction device (EM38-MK) to cover this gap. An EM38-MK was used to measure soil apparent electrical conductivity (ECa) as a covariate to determine soil salinity status and soil water content θ post irrigation at four depth layers (Hz: 0–0.25 m; Hz: 0–0.75 m; Vz: 0.50–1 m). The inverse distance weighting method was used to generate the spatial distribution thematic layers of electrical conductivity. The statistical measures showed an R2 = 0.87; r > 0.7 and p ≤ 0.05 on correlation of ECa and SWC. Based on the South African salinity class of soils, the area was not saline ECa < 200 mS/m. The EM38-MK can be used to estimate soil salinity and SWC variability using ECa as a proxy, allowing precise estimations with depths and in space. These findings provide key information that can aid in irrigation scheduling and soil management.
Oil Sands Wetland Ecosystem Monitoring Program Indicators in Alberta, Canada: Transitioning from Pilot to Long-Term Monitoring
Authors: Mahoney Craig , Montgomery Joshua , Connor Stephanie , Cobbaert Danielle
Published: May 2023

Boreal wetlands within the oil sands region of Alberta, Canada, are subject to natural and anthropogenic pressures, resulting in the need for monitoring these sensitive ecosystems to ensure their protection. This study presents results from Canada’s pilot Oil Sands Monitoring (OSM) Wetland Program. This study is part of a project that seeks to assess and determine which of a selection of wetland indicators is suitable for identifying changes to wetland ecosystem “states” within a regional wetland monitoring program resulting from the effects of oil sands development. Specifically, this study seeks to identify indicators that can detect changes in a wetland ecosystem “state” using data from a 3-year pilot of the OSM Wetland Program and identify potential high-level oil sands-related pathways through which changes in states may occur, where appropriate. The monitoring data acquired during the pilot program are synthesized to identify preliminary trends and programmatic knowledge gaps, and future recommendations for an improved long-term “core” monitoring program are discussed. This study does not seek to attribute changes in wetland states measured via indicators to specific oil sands pressures but focuses on identifying those indicators that are sensitive enough to identify change over time. The results suggest that water quality, benthic invertebrates, and vegetation indicators can identify changes in wetland states over time, whereas wildlife indicators are inconclusive. Further, it is recommended that hydrometeorology data are acquired in parallel to other indicator data for contextualizing climate conditions. The findings from this work provide insights for developing and transitioning the OSM Wetland Program to a long-term effort, in addition to providing information for other regional wetland monitoring programs.
Analysis of Water Infiltration Characteristics and Hydraulic Parameters of Sierozem Soil under Humic Acid Addition
Authors: Ma Xian , Bai Yiru , Liu Xu , Wang Youqi
Published: May 2023

The farmland in Yinchuan is composed of sierozem soil, which is characterized by high sand content and low organic matter content, resulting in poor water-holding capacity and weak soil structure. Humic acid is a natural organic polymer soil amendment. It is critical to study how humic acid affects soil water infiltration in sierozem soil at the microlevel. A one-dimensional vertical infiltration experiment was conducted to explore how adding different amounts of humic acid (0, 1%, 2%, 3% and 4%) affected the infiltration characteristics and hydraulic parameters of the sierozem soil. The results revealed that the wetting front and cumulative infiltration decreased with the increase in humic acid addition. When the infiltration time was 90 min, the wetting front of the 1%, 2%, 3% and 4% treatments was 6.50%, 10.00%, 15.00% and 21.00% lower than CK (0 for CK), and the cumulative infiltration volume was 4.50%, 11.14%, 18.42% and 23.60% lower than CK, respectively. Among the three infiltration models created by Philip, Horton and Kostiakov, the Kostiakov model (R2 > 0.95) could more accurately describe the soil water infiltration process in the study area. After infiltration, the moisture content of each soil layer increased with the increase in humic acid, which improved the water-holding capacity of the sierozem soil. Using Hydrus-1D to calculate soil hydraulic parameters, we found that the humic acid addition affected the hydraulic parameters. With the increase in the amount of humic acid addition, the retention water content θr and saturated water θs were positively correlated with the humic acid addition amount and negatively correlated with the saturated water conductivity Ks and the reciprocal of air-entry α. The results showed that humic acid could increase the water-holding capacity of soil and improve the rapid water loss and poor water-holding capacity of sierozem soil.
Social Isolation and Online Relationship-Risk Encounters among Adolescents with Special Educational Needs
Authors: El-Asam Aiman , Colley-Chahal Lara Jane , Katz Adrienne
Published: May 2023

While all vulnerable adolescents are more at risk online than their non-vulnerable peers, those with special educational needs (SEN) require targeted and specialised support. Although they are not a homogenous group, SEN adolescents commonly experience social isolation and a lack of connection or meaningful relationships with peers in their offline lives. Many perceive the internet as a route to alternative means of communicating and interacting with others. Accessibility tools enable autonomous access to the online world, which offers support groups, new friends, entertainment, and connections. This can lead to both potential online relationship-risk encounters and positive experiences. With the attraction of online environments comes the need for digital skills and awarness of possible online risks, yet for adolescents with SEN, their difficulties dictate a need for more than rules, controls, and digital skills. In this study, 4894 adolescents aged 13 to 17, of whom 1207 had SEN, completed the Cybersurvey 2019, an online questionnaire about their digital life. Adolescents were asked about the benefits of using the internet, their online safety support, offline social support, and any online relationship-risk encounters. All participants were recruited through their schools. Descriptive statistics and multiple analysis of variance tests showed that, compared with their peers, adolescents with SEN experienced significantly more social isolation and less parental online safety support. They were also more likely to use the internet for positive purposes, such as socialising and coping. Overall, adolescents with SEN encountered more online relationship risks than their non-SEN peers, with older teens more likely to encounter such risks than younger peers, regardless of their SEN status. Multiple analysis of variance tests also identified that boys perceive internet use as positive to a greater extent than girls, suggesting a gender difference in experiences of the digital environment. A multiple linear hierarchical regression revealed that SEN status, age, social isolation, poor parental online safety support, and greater perceived positive internet use, all significantly predicted online relationship-risk encounters. This article discusses important implications and recommendations for policy and practice related to SEN and online safety and highlights areas for future research to consider.

Published: May 2023

The approach proposed earlier by the authors to a statistically justified search for structures in data of different nature is applied to the problem of statistical quality control. The need to verify that measurement results are independent and identically distributed values (random hypothesis) arises in scientific research, quality control of laboratory analyzes and production processes. Popular tests of randomness or patternless in the existing literature are usually global and do not allow user to identify possibly existing local violations of randomness. The proposed local tests are two-stage. At the first stage, a list of sections is compiled where there is reason to suspect a violation of randomness due to the presence of a certain pattern. Each such section is characterized by two numbers – length and degree of severity. On the plane of parameters (length, severity) a critical region is built, upon entering which this section is declared being significant. The corresponding local modification of the classical runs test is considered. In addition, two more new nonparametric tests have been proposed to search for sections with excessively similar and vice versa strongly fluctuating data. The construction of tests is simplified when the ranks of measured values are replaced by the corresponding empirical p values which are uniformly distributed and nearly independent if hypothesis of randomness is true.

Composition and characteristics of excavated materials from a legacy waste dumpsite: Potential of landfill biomining
Authors: Ghosh Arghya , Kartha Suresh A.
Published: May 2023

Landfill biomining (LFBM) has been proposed as a viable method for the reclamation of legacy waste dumpsites as well as the subsequent recovery of valuable resources and land value spaces. Despite these advantages, the potential of LFBM faces a significant challenge due to the composition, characteristics and end-use of the excavated materials. This paper assesses the composition of the excavated waste obtained during the LFBM operation of the four legacy waste heaps at the Boragaon dumpsite in North-East India and determines the physicochemical characteristics crucial for the material and energy recovery from the key reclaimed fractions. The compositional analysis revealed that the proportion of combustible and non-combustible fractions decreases from the youngest heap HP4 to the oldest heap HP1 due to variations in the consumption habits of the local community and the inadequate recycling of recyclable materials. However, the proportion of fine fraction (FF) shows an increasing trend from HP4 to HP1, suggesting enhanced biodegradation of easily degradable waste over the years. The proximate and energy content analysis suggest that refuse-derived fuel (RDF) preparation is the most suitable valorization option for the combustible fractions since surface defilements are too high for good quality material recovery. The elevated amount of organic matter and leachable heavy metals indicate that unrestricted reuse of FF as earth-fill material can cause long-term settlements and groundwater contamination, respectively. Even though every dumpsite is different in characteristics, the findings of this case study can assist in developing new strategies for recycling excavated waste.

Introduction. Currently, there is no unequivocal opinion on the optimal list of studies for the genetic diagnosis of oncohematological disorders in children and adults. These discrepancies are due to the limited technological capabilities of laboratories, the rapid development of science, and a significant expansion of the range of new molecular markers, that are attractive, but only for a limited group of patients. Moreover, in modern conditions of limited access to resources, it seems important to bring desires, interests and opportunities to a common denominator.   Aim — to develop unified approaches to the cytogenetic and molecular genetic diagnosis of oncohematological diseases in children and adults based on the consensus opinion of the panel of experts.   Main findings. The review proposes the arrangement of cytogenetic and molecular genetic diagnostic tests in oncohematological disorders in children and adults into 3 categories depending on the frequency of genetic aberrations, the study complexity and the prognostic impact. Based on this and taking into account the diagnosis and age of patients, the minimal and optimal lists of clinically significant parameters and research markers were identified. The basic preanalytical principles for conducting cytogenetic and molecular genetic studies in oncohematology are pointed out. A brief description of a conventional cytogenetic study and a polymerase chain reaction for the diagnosis of oncohematological diseases is given. The paper also focused on the need for reference diagnostics of cytogenetic and molecular genetic studies in oncohematology. The article is addressed to the specialists in the field of laboratory genetics, clinical laboratory diagnostics, but may also be of interest to hematologists, pediatric oncologists and doctors of related branches.

Introduction. Only a massive radiation accident, and not individual incidents heterogeneous in terms of exposure conditions, contributes to the revision and development of knowledge and therapeutic capabilities in acute radiation syndrome (ARS).   Aim — to present recommendations based on literature data and own clinical experience for the diagnosis and treatment of a typical bone marrow form of ARS from relatively uniform irradiation.   General information. An analysis of the literature on the problem of diagnosis and treatment of ARS was carried out, and the experience of providing medical care to victims of the April 26, 1986 radiation accident at the Chernobyl Nuclear Power Plant (104 patients with OLB) in the clinical department of the A.I. Burnazyan State Medical Center of the FMBA of Russia is summarized. When admitting individuals involved in a radiation accident into a medical institution, one of the most important measures of action is to conduct medical sorting, that is, the distribution of victims into groups according to the principle of need for homogeneous therapeutic, preventive and evacuation measures, depending on medical indications, specific conditions of the situation and the prognosis of the patient's survival based on dose assessment and prediction of the severity of the course of ARS by all available methods of physical and biological dosimetry (calculation method, simulation of the situation, clinical signs of the primary reaction to radiation, cytogenetic method, absolute number of peripheral blood lymphocytes during the first 8 days after irradiation, dynamics of the absolute number of peripheral blood neutrophils, etc.). The scope of therapeutic measures depends on the severity of the developing ARS, including the therapy of infectious complications and hemorrhagic syndrome. The appointment of myelostimulation in order to reduce the depth and duration of radiation-induced cytopenia is recommended when irradiated at a dose of more than 1.5 Gy. Transplantation of allogeneic hematopoietic stem cells in ARS is recommended in a narrow dose range from 10 to 13 Gy in the absence of concomitant severe injuries and burns. Recommendations for the treatment of oropharyngeal and intestinal syndromes are given.

The problems of creating tractors, self-propelled chassis, forestry and agricultural machines of special designs for the mechanization of crop production, land reclamation and construction in hard-to-reach conditions of forest, agricultural and mountain lands are considered in the work. A comparative analysis of design solutions that have found application in domestic and foreign tractors used in the performance of technological and transport operations on sloping lands and badlands in agriculture and forestry is given. It is noted that a number of models of universal row-crop tractors provide for the possibility of increasing stability by turning the housings of the remote final drives relative to the rear axle housing. For tractors, at the same time, the wheelbase increases and the ground clearance (ground clearance) decreases. It is indicated that the analysis of the features of the operation of wheeled tractors on the slopes made it possible to substantiate the methods and means that improve their main indicators: differential lock; lowering the center of gravity; the use of tires with high lugs, additional steel wheels, lugs, expanders; the use of half-tracks and wheeled tractors with a 4K4 wheel arrangement. The advantages and disadvantages of using tracked and wheeled tractors as the base machine have been established. Slope preference for tractors with front drive axle. Such tractors, equipped with the previously listed devices, have better traction properties, maneuverability and controllability, approaching caterpillar tractors in these indicators. Recommendations for the implementation on slopes, forest and agricultural lands of all-wheel drive low-clearance wheeled tractors are given in the work. In conclusion, it is indicated that, despite the considered features, when creating tractors for working on small-contour plots located on slopes up to 25 °, preference is given to wheeled low-clearance tractors, which is caused by a cheap design due to minor design changes compared to the basic models.

The effective operation of the machine and tractor fleet (MTF) of a modern agro-industrial complex requires monitoring of its technical condition by a system of repair and maintenance bases (RMB). A methodology for substantiating the structure and characteristics of the ROB system using special decision support systems (SDSS) is proposed, which will make it possible to implement the maintenance strategy “by actual state”, as well as reduce the recovery time of the MTF. The methodology includes a set of interrelated models: forecasting and diagnosing the technical condition of the MTF, the functioning of the system for ensuring the operability of the MTP and the formation of cost dependencies on the functioning of the RMB system. Algorithms were applied: redistribution of costs between maintenance activities (TO) and current repairs (TR); solution of the optimization problem based on the modified Nelder-Mead method. It was revealed that the small value of the maintenance interval allows to achieve sufficiently high values for the coefficient of technical readiness (Kg). It is shown that the main measure that allows to reduce operating costs and positively influence the value of Kg is the rational distribution of time for carrying out checks used during maintenance of the MTF sample. The use of 2-6 specialists makes it possible to ensure the duration of maintenance according to the state of the ICC unit from two to four hours. Deviations of more than 30 minutes at TR from the normative values of the recovery time led to a sharp decrease in the level of availability at the current level of the sudden failure flow parameter. Attracting an average of 3 - 4 specialists is required to complete the TR. It has been established that the main condition for the optimal operation of the MTF sample is individual monitoring of its technical condition, which makes it possible to reduce the duration of adjustment and repair measures by 40%. The condition for the effectiveness of the RMB system is the presence of at least four people of engineering and technical staff in the teams that carry out these activities. The total cost reduction for ensuring the working condition of the studied equipment was about 18 - 20%.

Works on conservation of the internal cavities of internal combustion engines and, first of all, cylinder liners are carried out before placing combine harvesters for off-season storage, for which equipment manufacturers recommend using special conservation technologies and specialized conservation oils. These measures to protect machines from corrosion are practically not used in real operation, primarily because of the high costs of their implementation. A low-cost resource-saving technology for protecting combine harvester engines from corrosion-mechanical wear is being developed at FSBNU VNIITiN by developing a conservation oil composition based on used engine oil. A method for cleaning waste oil from contaminants has been developed. Studies have been carried out to determine the rational composition of the oil, including the use of polymerized rapeseed oil and gun grease as additives that increase anti-wear and anti-corrosion properties. The optimal oil polymerization time has been established to be at least 20 hours, which makes it possible to increase the viscosity of the oil and increase the parameters of the protective film being formed. PVK gun grease is considered as a corrosion inhibitor in the composition of conservation oil. A small amount (3 l) of purified motor oil M-10G2 is taken for mixing PVC with base oil, the mixture is heated to 100°C and mixed for 20 minutes. The resulting enriching mixture of purified oil with dissolved polymerized rapeseed oil and PVC lubricant was added to the main volume of purified oil at a concentration of 3%, 6%, 9%. Based on the studies carried out, the dependences of the change in viscosity were obtained. It has been determined that a 6% additive is a rational concentration for adding an enriching mixture. An assessment of the possibility of precipitation of oil components during their storage showed acceptable values for the thickness of the sediment layer, not exceeding 1 mm. As a first approximation, a new oil composition has been developed, which is easily accessible for production under the conditions of agricultural enterprises of the agroindustrial complex.

lack of soft tissue cover of the shaft of tibia and increased incidence of open fracture make it difcult for treatment and high rate of non-union and
infection. So aggressive treatment with adequate wound debridement and IV antibiotics and fracture stabilization is necessary. Various methods
for fracture stabilization include plating , intra-medullary nailing or external xator application. This prospective study was done among 39
patients who sustained compound tibial fractures(Gustilo grade II , IIIa and IIIb) and were admitted in Department of Orthopaedics, Government
Medical College, Thrissur. Functional and clinical outcome is assessed at 1st and,2nd week followed by 1st , 3rd & 6th months using modied
johner and wruh's criteria.The post operative outcomes- intermediate and nal, were assessed and analysed for statistical signicance using
Microsoft Word, Microsoft Excel and statistical software IBM-SPSS (International Business Machines- Statistical Product and Service
Solutions) ver18, using appropriate statistical tests. The patients were in the age group of 23 to 63 years and with a mean age of 41.59 years.
Males were predominant. Most common mode of injury is road trafc accident which accounts for 71.8% of cases. Majority of injury were type 2
(61.5%) Gustilo-Anderson classication. There were 12.8% Excellent results, 38.5% Good results, 10.3% Fair results and 38.5% Poor results
according to Modied Johner and wruh's criteria. External xation is a simple and effective means of treating of open tibial shaft fractures
especially in type 2 , type 3A & type 3B fractures, the external xator as a treatment in open tibia fracture is a valuable tool as it gives advantage to
less operative time and intra-operative blood loss. There is easy access to the soft tissue and easy wound management with a stable xation can be
obtained

Symmetrical peripheral gangrene is a known entity characterized by gangrene of two or more sites in absence of obvious
large vessel obstruction. Such complications in common tropical infectious disease like Malaria is rare. Pathogenesis and
treatment of symmetrical peripheral gangrene in malaria is unclear. However, can be attributable to cyto-adhesion, rosetting, and agglutination.
Due to its rapid progression and sinister prognostic implications aggressive multidisciplinary team effort is essential. we present herewith a rare
case of symmetrical peripheral gangrene in severe mixed Malaria.

The physical properties of excipients are very important to know for the manufacture of good tablets. Starch or amylum is an additional material that is often used in the manufacture of tablets. The physical properties of starch or powder that are good for tablets can give the desired effect if they have good quality. Unmodified starch does not have good compressibility and has great friability, and capping will occur in the tablet. Taro taro as a potential starch can be used as an excipient in the manufacture of tablets because it has a high starch content. Taro taro used as an excipient needs to be modified physically and chemically to produce derivatives that have better and more specific pharmaceutical characteristics, especially for the manufacture of tablets. The purpose of this study was to determine whether the physical properties of taro starch matched the parameters of good physical properties. Tests carried out included organoleptic tests which obtained powder like flour, had no odor, had no taste and had a white color, Knowledge test obtained dark blue in modified taro starch solution after being given iodine, Microscopic tests obtained taro starch results which had the arrangement is clustered with the hilus located in the middle, the shape of the hilus is in the form of a point, a straight line. The water content test obtained the water content value of each modified starch based on the length of drying time using a drying cabinet of 9.40% for drying for 24 hours, 8.42 % for drying for 48 hours, and 7.9% for drying for 72 hours and pH Test Produces a pH value of 6.52 for drying for 24 hours, 6.22 for drying for 48 hours and 5.92 for drying for 72 hours.
