Curd cheese is a traditional dairy product that, in recent years, has increasingly been supplemented with various functional additives aimed at enhancing its aroma and flavor profile, improving overall quality, and extending shelf-life. The objective of the present study was to conduct a comparative evaluation of changes in selected physicochemical, microbiological, and sensory parameters of curd cheese enriched with 0.01% essential oils derived from dill (Anethum graveolens L.), cumin (Cuminum cyminum L.), and caraway (Carum carvi L.) fruits. Fatty acid profiling revealed a reduction in saturated fatty acids and an increase in oleic and linoleic acids in essential oil-enriched curds compared with the control. Amino acid analysis showed higher levels of essential amino acids, particularly leucine and lysine, suggesting enhanced protein retention and balanced proteolysis. Organic acid content, including lactic acid, was slightly lower in treated samples, indicating moderate fermentation activity, while microbiological analyses confirmed the absence of spoilage or pathogenic organisms. Essential oils also contributed to higher moisture retention, reflected in slower increases in dry matter during storage. Sensory evaluation by a consumer panel indicated that all curds were well accepted. The findings demonstrate that dill, cumin, and caraway essential oils can be used as functional additives in low-fat curd to enhance nutritional value, improve product stability, and maintain consumer acceptance during storage.
Deploying artificial intelligence in warfare and national security: A qualitative exploration of strategic implications for Pakistan
(Routledge, 2026) Shahzad, Shahbaz Ahmed; Anser, Muhammad Khalid; Haq, Ihtisham Ul; Aamir, Alamzeb; Zaman, Khalid
The study examines Pakistan's artificial intelligence (AI) strategy for national security and defence. It identifies AI trends and effects using qualitative data from 105 military, intelligence, cybersecurity, and government specialists. Thematic research indicates AI improves military decision-making, intelligence synthesis, surveillance, and real-time risk assessment. Participants emphasised the importance of AI in military resource allocation, target precision, predictive analytics for terrorist activities, and border security. The findings reveal that AI enhances operational efficiency by improving situational awareness, threat detection, and reducing human error. Specialists are debating the ethical and strategic implications of algorithmic responsibility and autonomous weapon systems. Many consider the absence of institutional and legal frameworks for AI in defence a significant policy gap. AI may improve digital protective layers while rendering them more vulnerable to attacks. Due to inadequate training facilities and talent development, shortages in domestic AI research and military innovation capabilities are prevalent. Experts recommended investing in AI-driven defensive ecosystems, ethical protections, and localised AI procedures. The findings suggest that AI could transform Pakistan’s military strategy with adequate leadership, preparation, and ethical considerations.
A new frame for non-lightlike curves in Minkowski 3-space: hybrid frame
(Walter de Gruyter GmbH, 2026) Öztürk, İskender; Çelik, Oğuzhan; Çakır, Hasan
In this study, we introduce a hybrid frame consisting of elliptic, hyperbolic, and parabolic vectors for the study of non-lightlike curves in Minkowski 3-space. In contrast to classical approaches that treat different causal characters separately, the proposed frame allows these vector types to be considered within a single framework. We define the curvature and torsion functions with respect to the hybrid frame and examine their relations to the corresponding Frenet invariants. In addition, we investigate the osculating spheres of non-lightlike curves using this frame and obtain characterizations of their centers. The results provide an alternative formulation for the geometric analysis of non-lightlike curves and contribute to the existing theory of curves in Minkowski space.
Taxonomic notes on persicaria lapathifolia (Polygonaceae/ Polygonoideae) focusing on Türkiye
(Istanbul University-Cerrahpasa, 2026) Gültepe, Mutlu; Kundakçı, Suzan; Makbul, Serdar; Coşkunçelebi, Kamil
Persicaria lapathifolia has exhibited significant variation in its external morphological characteristics (e.g., stem dotting, leaf shape, leaf and ocrea indumentum, perianth properties), leading to different classifications by many taxonomists. According to recent records, P. lapathifolia is represented by P. lapathifolia subsp. brittingeri, P. lapathifolia subsp. lapathifolia, and P. lapathifolia subsp. nodosa in Türkiye. In the present study, P. lapathifolia is evaluated, focusing on morphological and molecular evidence (internal transcribed spacer sequences) inferred from extensive examination of both authentic herbarium specimens (from national and international collections) and newly gathered field samples. Morphological observations revealed that members belonging to Turkish subspecies exhibited very similar characteristics that do not provide sufficiently diagnostic features to describe the infraspecific variation of P. lapathifolia. Also, phylogenetic analyses further support the morphological similarities, confirming the lack of clear genetic differentiation among the members of Turkish specimens. When the specimens belonging to subsp. brittingeri and subsp. nodosa collected from Türkiye were examined in detail, and it was determined that they clearly belong to subsp. lapathifolia. This morphological similarity is also highly supported by phylogenetic analyses based on internal transcribed spacer data. All these findings show that P. lapathifolia is represented by P. lapathifolia subsp. lapathifolia in Türkiye. Therefore, the extended description, chorology, and phylogenetic relationships of the P. lapathifolia subsp. lapathifolia are presented in detail for the first time in the present article.
Leonardo cartan numbers and related fibonacci–lucas structures
(Wiley, 2026) Çakır, Hasan; İskender, Ö.
This paper investigates the Leonardo Cartan numbers, defined as an extension of the classical Leonardo sequence through additional algebraic structures. The recurrence relations of these numbers are established, and various summation formulas are derived. Furthermore, key mathematical identities, including Catalan’s and Cassini’s identities, are obtained within the framework of Leonardo Cartan numbers. The relationships among Fibonacci, Lucas, and Leonardo sequences are also explored, thereby highlighting their interconnections. By employing Binet’s formula, several fundamental properties of Leonardo Cartan numbers are confirmed, contributing to a deeper understanding of their algebraic structure.
