Steppe-Derived Glyphosate-Tolerant Pseudomonas sp. ADL-13 and Paenibacillus sp. ZHS-9 Strains with Plant Growth-Promoting Traits and Broad Abiotic Stress Tolerance

The integration of plant growth-promoting bacteria (PGPB) into sustainable agricultural practices represents a promising strategy for improving crop productivity and stress resilience. We characterized two newly isolated steppe-derived, glyphosate-tolerant bacteria, Pseudomonas s...

Adsorption and Photocatalytic Activity of Covalent Organic Frameworks for Environmental Remediation: A Review of Density Functional Theory Studies

The contamination of water resources by heavy metals, radionuclides, and organic pollutants demands efficient materials for water treatment. Covalent organic frameworks (COFs) are promising candidates owing to their tunable porosity and functionalizable frameworks. This review ex...

GIS-Based Spatial Assessment of Urban Engineering Geological Conditions Using Borehole and Laboratory Data: A Case Study of Pavlodar, Kazakhstan

Assessment of urban engineering geological conditions is often constrained by the uneven distribution and variable completeness of site-investigation data. This study presents a GIS-based spatial assessment of ground conditions in Pavlodar, Kazakhstan, using archival borehole rec...

Development of Functional Lamb Pâté Enriched with Edible Lamb By-Products and Pulse Ingredients: Physicochemical, Nutritional and Safety Evaluation

The growing demand for nutritionally enriched and sustainable meat products has stimulated interest in the utilization of edible animal by-products and plant-based ingredients. The present study aimed to develop lamb pâté formulations containing lamb liver, lamb heart, mung bean,...

Recombinant Expression and Functional Analysis of GH2 β-Galactosidases Derived from Lactobacillus delbrueckii subsp. bulgaricus NSP1 and Streptococcus thermophilus RB16

GH2 β-galactosidases are important industrial biocatalysts for lactose hydrolysis and prebiotic galacto-oligosaccharide (GOS) synthesis. Here, lacZ genes from Streptococcus thermophilus RB16 (StLacZ) and Lactobacillus delbrueckii subsp. bulgaricus NSP1 (LbLacZ) were cloned, seque...

Geometric ornament as material knowledge: Ethnogeometric structures of spatial cognition

This article proposes a method for analysing recurring geometric relationships in Chalcolithic Botai material culture in northern Kazakhstan. Ornamented artefacts, dwelling architecture and settlement layout are examined without assuming a single symbolic code or historical conti...

Air Quality and Emission Trends Following the 2021 Environmental Code Reform in Kazakhstan Across Regions and Industrial Sectors

The 2021 revision of the Environmental Code of the Republic of Kazakhstan was introduced to align with the World Health Organization (WHO) air quality guidelines and the national carbon neutrality strategy for 2060. The revised Code reflects a transformation of environmental gove...

Calibrated Prediction of Students’ Next Responses in Digital Mathematics Learning: A Completion-Ordered and Cold-Start-Aware Framework

Digital mathematics platforms support probabilistic prediction of subsequent student responses, but temporal ordering, score comparability and calibration affect the validity of evaluation. We evaluated AdaptiveMath-AI on a deterministic cohort of 385,037 Eedi interactions from 2...

Analytical Solutions of the Fractional Derivative Chen–Lee–Liu Equation

This paper investigates a Schrödinger-type fractional-order nonlinear equation known as the Chen–Lee–Liu equation. The fractional properties of the model are described by means of the reduced M-fractional derivative. Using a traveling-wave ansatz and a change in variables, the or...

Designing the waiting experience: How order tracking shapes consumer engagement and loyalty

The post-purchase waiting period is an important yet underexamined stage of the digital customer journey. Consumers increasingly interact with order tracking systems during this phase, yet research has treated tracking primarily as a logistics tool rather than an experiential tou...

Multi-Criteria GIS Prioritization of Urban Housing Renovation: A Case Study of Astana, Kazakhstan

Housing-renovation programs in post-Soviet cities typically rely on a single wear-percentage threshold to decide which buildings are demolished, disregarding the building age relative to normative service life, population density, and construction logistics. This study develops a...

Elemental Composition, Sources, and Health Risks of Ambient PM2.5 in Ust-Kamenogorsk (Oskemen) and Pavlodar, Kazakhstan

Atmospheric pollution by fine particulate matter (PM2.5) poses a severe threat to public health in industrial regions of Kazakhstan, such as Ust-Kamenogorsk and Pavlodar, where a sharp continental climate exacerbates toxic element accumulation. This study aimed to compare the ele...

GeoProtoNet: texture-aware few-shot lithology classification from rock imagery using frozen DINOv2 features

Abstract Rapid lithology identification on open-pit bench faces is typically performed manually by geologists, yet it is subjective, inconsistent under variable field conditions, and cannot be scaled to the large image volumes required by conventional supervised deep learning. We...

Exploring Whether Neuropsychological Functioning Moderates the Association Between Delinquent and Criminal Involvement and the Likelihood of Arrest

Not all criminal offenders are apprehended for their crimes and subsequently processed through the criminal justice system. Although a line of research has examined reasons why there is differential processing of offenders, there remain significant gaps in this body of research....

Waste-Derived Natural Polymer Biosorbents for Toxic Metal Ions: Structure–Sorption Relationships, Modification Strategies, and Prospects for Solid-Phase Sensing

Waste-derived natural polymers offer a route to low-cost sorbents for toxic metal ions, but reported performance is difficult to compare because precursor composition, polymer processing, modification, and experimental conditions vary widely. This critical review examines silk fi...

Integrative analysis of lncRNA-miRNA-mRNA expression profiles in esophageal squamous cell carcinoma tissues

Esophageal cancer represent a major global health concern. Esophageal squamous cell carcinoma (ESCC) is the most prevalent histological subtype and exhibits pronounced population-specific variation in incidence. Unfortunately, the main cause of this geographical difference in dis...

Physiological, Biochemical, and Molecular Responses of Potato Cultivars to Osmotic Stress Under In Vitro Shoot Culture

Drought is a major limiting factor for potato productivity. This study examined two Kazakh potato cultivars, Tokhtar and Aksor, under osmotic stress induced by polyethylene glycol (PEG)-6000 using an integrated physiological, biochemical, and molecular approach. We evaluated plan...

Spatiotemporal heterogeneity in the association between ambient air pollution and respiratory morbidity in the industrial Region of East Kazakhstan

Ambient air pollution remains a significant risk factor for respiratory morbidity, yet its spatiotemporal associations in the industrial regions of Central Asia remain insufficiently studied. To identify the association between airborne pollutants and respiratory morbidity in fou...

Transcendence as an Operator and the Witness as its Mechanism. An extension of the DIKW hierarchy for auditable machine-assisted inquiry

The Data–Information–Knowledge–Wisdom (DIKW) hierarchy describes as-cent within a fixed base of data. It is silent on where the base comes from, on what happenswhen the phenomenon under study has no category in the base, and on what lies abovejudgement. This paper reports an exte...

Stage-Oriented Text Classification for Russian-Language Clinical and Genetic Documents: Pre-Genetic Triage and Post-Genetic Report Interpretation

The growing volume of unstructured clinical and genetic text calls for automated processing methods that can meaningfully support clinical decision-making. Most existing work, however, treats the analysis of patient clinical descriptions and the interpretation of genetic reports...
