Vitamin E, selenium, and polyunsaturated fatty acid concentrations and glutathione peroxidase activity in tissues from pigs with dietetic microangiopathy (mulberry heart disease)
Authors: Rice Desmond A. , Kennedy Seamus 
Published: February 2025

SUMMARY
Tissues of 27 pigs with spontaneous dietetic microangiopathy (dm) and of 27 control pigs that died of causes unrelated to vitamin E and selenium (E-Se) deficiency were analyzed for α-tocopherol, Se and polyunsaturated fatty acid (pufa) concentrations and for glutathione perioxidase (gsh-Px) activity. These variables (except for gsh-Px) also were measured in rations fed to control pigs and pigs with dm. Swine with dm had lower heart and liver α-tocopherol concentrations than did control pigs. Heart and kidney Se concentrations and heart and liver pufa concentrations were similar in pigs of either group. Diets fed to both groups of pigs contained similar content of α-tocopherol, Se, oil, and pufa; α-tocopherol and Se concentrations in the diets of both groups of pigs were high. In spite of apparently adequate amount of dietary α-tocopherol, results indicate that pigs with dm had lower tissue α-tocopherol concentration than did control pigs. Spontaneous dm is associated with altered α-tocopherol metabolism, but is unrelated to alterations in dietary Se and pufa contents and tissue Se and pufa concentrations and gsh-Px activity.
Efficacy of ivermectin against experimental and natural infections of Gasterophilus spp in ponies
Authors: Bello Thomas R. 
Published: February 2025

SUMMARY
Antiparasitic efficacy of ivermectin against migrating Gasterophilus intestinalis was evaluated in 36 treated and 24 nontreated (n = 12) or vehicle-treated (n = 12) ponies experimentally and naturally infected with G intestinalis and naturally infected with G nasalis. Each pony was experimentally infected with 500 G intestinalis 1st instars in 2 divided doses on days - 14 and - 7 before treatment. On day 0, ivermectin was administered at the rate of 200 μg/kg of body weight by iv (n = 12) or im injection (n = 12) or given as an oral paste (n = 12). Ponies were euthanatized and necropsied 21 days after treatment. In each nontreated or vehicle-treated pony, late 1st-, 1st- to 2nd- instar molt, and early 2nd-instars of G intestinalis were found in the mouth, and 2nd- and 3rd instars of G intestinalis and 3rd instars of G nasalis were found in the stomach. Bots were not found in any ivermectin-treated pony and, thus, ivermectin was 100% effective against oral and gastric stages. Adverse reactions were not observed in ponies given ivermectin by im injection or orally, but 1 pony given the vehicle iv and 1 pony given ivermectin (in the vehicle) iv had an anaphylactic reaction, resulting in death of the ivermectin-treated pony. It was speculated that the adverse reaction was caused by histamines released in response to vehicle components given by iv injection.
Effects of atracurium administered by continuous intravenous infusion in halothane-anesthetized horses
Authors: Hildebrand S. V , Hill T. 
Published: February 2025

SUMMARY
Atracurium (0.4 mg/ml in isotonic NaCl solution) was administered by iv infusion to 7 healthy adult horses for 2 hours. Over the 2-hour period, a 95 to 99% reduction of train-of-four hoof-twitch response was maintained by 0.17 ± 0.01 mg of atracurium/kg of body weight/h, for a total of 161 ± 6 mg of atracurium (mean ± sem) for horses 1 to 4, 6, and 7. Horse 5, a mare in estrus, required 0.49 mg of atracurium/kg/h to maintain comparable relaxation. Hoof-twitch recovery time from 10 to 75% of baseline strength was 19.8 ± 2.5 minutes for all horses. The 10 to 75% recovery time for horse 5 was 18 minutes. Recovery time from discontinuation of halothane until standing was 86 ± 14 minutes (range, 55 to 165 minutes). Horse 5 had a 165-minute recovery. Regarding recovery from anesthesia, 3 recoveries were rated as excellent, 1 recovery good, and 2 recoveries as fair. Horse 5 laid quietly until she stood with 1 strong, smooth effort.
Clinical and pathologic effects of spiral and total ring prostheses applied to the cervical and thoracic portions of the trachea of dogs
Authors: Fingland Roger B. , Weisbrode Steven E. , DeHoff William D. 
Published: February 2025

SUMMARY
This study compared the short-term clinical and pathologic effects of spiral and total ring prostheses, applied to the cervical and thoracic portions of the trachea of dogs via a combined intercostal thoracotomy and ventral cervical midline approach. The effect of intraluminal placement of synthetic monofilament nonabsorbable suture also was evaluated.
Eleven small-breed dogs were randomly allotted to 3 groups. Group 1 (n = 3) were controls that had been treated by sham operation, group 2 (n = 4) had polypropylene spiral prostheses applied to the cervical and thoracic portions of the trachea, and group 3 (n = 3) had total ring prostheses applied to the cervical and thoracic portions of the trachea. All dogs were euthanatized and necropsied 8 weeks after surgery.
Clinical complications were minimal and limited to mild, short-term lameness and coughing. Three and 6 weeks after surgery, radiographs were within normal limits in all dogs. Tracheoscopy confirmed maintenance of tracheal lumen diameter and integrity of the mucosal epithelium in all dogs.
Gross and microscopic postmortem findings were similar in groups 2 and 3. Mild adhesions were present between prostheses and adjacent structures. Similar adhesions were present where prostheses had been applied and subsequently removed in group-1 dogs. Histopathologic abnormalities included mild to moderate adventitial and periprosthetic fibrosis and mild adventitial inflammation associated with polypropylene spiral prostheses and total ring prostheses. The majority (70%) of intratracheal sutures evaluated were covered by microscopically normal ciliated mucosal epithelium by 8 weeks after surgery.
Polypropylene spiral prostheses and total ring prostheses applied to the cervical and thoracic portions of the trachea of dogs in the manner described appear to be tolerated well and produce a minimal tissue response over the study period.
Dermatosis associated with feeding generic dog food: 13 cases (1981-1982)
Authors: Sousa Candace A. , Stannard Anthony A. , Ihrke Peter J. , Reinke Susan I. , Schmeitzel Lynn P. 
Published: February 2025

Summary
The records of 13 dogs with a crusting dermatosis of the mucocutaneous junctions, pressure points, and trunk were evaluated. All of the dogs had been fed corn- and wheat-based commercial dry dog foods that failed to meet the National Research Council's recommendations for balanced nutrition. The dermatosis in all 13 dogs resolved completely after the diet was changed to one that met the National Research Council's recommendations. The disease was similar to that which has previously been called canine dry pyoderma, but is now known to be a zinc-responsive dermatosis.
Financial impact of transmissible gastroenteritis in pigs
Authors: Mousing Jan , Vågsholm Ivar , Carpenter Tim E. , Gardner Ian A. , Hird David W. 
Published: February 2025

Summary
The financial impact of an epizootic of transmissible gastroenteritis in pigs was evaluated in a California sow herd through estimating growth, feed, and profit functions. Two groups of pigs were studied: pigs born before and surviving the epizootic (epizootic [E] pigs), and pigs born after the epizootic (postepizootic [PE] pigs). Short-term profits were maximized at 165 days for both groups of pigs, ranging from $47.14 for female E pigs to $60.32 for male PE pigs. Accordingly, it was concluded that pigs surviving or born shortly after a transmissible gastroenteritis epizootic are profitable to raise, if raised under management conditions similar to those in the study herd.

Ellipses surrounding convex bodies
Authors: Zamfirescu Tudor 
Published: February 2025

Abstract
If, for a double normal xx
* of a convex body K, an ellipse E ∋ x, x
* is included in K, we say that E is surrounded by the boundary of K. If, instead, in the plane of E, K is included in the convex hull of E, then we say that E is surrounding K. In this paper we investigate surrounding and surrounded ellipses, particularly circles. We do this for arbitrary convex bodies, for polytopes, for convex bodies of constant width, and for most convex bodies (in the sense of Baire categories).
Geometry of coupled dispersionless equations with Mannheim curves
Authors: Eren Kemal 
Published: February 2025

Abstract
In this paper, a special kind of curve pair associated with each other by the linear dependency between the principal normal vector of the first curve (called Mannheim curve) and the binormal vector of the second curve (called Mannheim partner curve) is considered. A connection with the coupled dispersionless equation and Mannheim curve pair is established. Also, the Lax pair of the obtained coupled dispersionless equation from the motions of any Mannheim curve pair is given. This gives us a significant condition based on the curvature and torsion of any Mannheim curve for its integrability since it is well-known that the Lax pair provides the integrability of di erential equations.

We show that, if either r < p or r > q with r < q(N − 1)/(N − q) in case q < N, then the eigenvalue set (spectrum) of the above problem is precisely (0, ∞). If r ∈ {p, q} then the corresponding spectrum is a smaller interval (d, ∞), d > 0. On the other hand, if r ∈ (p, q) with r < p(N − 1)/(N − p) in case p < N, then we are able to identify an interval of eigenvalues [λ*, ∞), where λ* is a positive number depending on r.
Obviously, the spectrum of the above problem coincides with the spectra of the Neumann-like, Robin-like, and Steklov-like eigenvalue problems corresponding to the cases when some of the functions α, β, γ

vanish.

Authors: Belkheiri Nadji , Rebizi Mohamed Nadjib 
Published: February 2025

Abstract
Chemistry plays a crucial role in everyday life, particularly in the kitchen, where its principles can enhance problem-solving skills and informed decision-making. This study aims to evaluate high school students’ understanding of applied chemistry in culinary contexts. A questionnaire was administered to 76 students, revealing that 42.6 % provided correct answers regarding the application of chemistry in the kitchen. The methodology involved analysing students’ responses to assess their awareness and appreciation of chemistry’s practical value. The findings suggest that promoting the application of chemistry principles not only fosters responsible citizenship but also optimises daily life benefits. Future research should explore effective strategies to enhance students’ engagement with chemistry in real-world contexts.
The Definition of Intelligence Activity
Authors: Britovšek Jaroš 
Published: February 2025

Abstract
Intelligence and counterintelligence (as activities) operate in a competitive environment, where they are crucial for gaining and maintaining a competitive advantage in decision-making processes. Intelligence involves the collection and analysis well as informing decision-makers. Counterintelligence, on the other hand, is focused on detecting and preventing the intelligence activities of adversaries. It is important to emphasize that intelligence activities are not intended to influence others but to provide decision-makers with timely and better insights than those available to their competitors. These activities are carried out at various levels and in different fields, differing in scale, capabilities, and limitations, but share the same goal – to achieve or maintain a competitive advantage in decision-making.

Published: February 2025

Abstract
The role of firefighters has evolved from traditional tasks like rescuing cats from trees and extinguishing house fires to more complex land, sea, and air rescues. The increasing demands for public safety necessitate rigorous training and high fitness levels for firefighters to manage their daily tasks effectively. In this study, final assessments of fitness and anthropometric parameters were gathered from 746 Malaysian firefighter recruits. A k-means clustering algorithm was utilized to group the performance levels of the firefighters whilst a quadratic discriminant analysis model was employed to predict the grouping of firefighters based on these parameters. Feature importance analysis was used to identify the most significant parameters contributing to model performance. Concurrently, the Mann-Whitney test was used to determine the essential anthro-fitness parameters differentiating between the groups of firefighters. The k-means clustering identified two performance groups: excellent and average anthro-fitness readiness (EFR and AFR) groups. The model demonstrated a mean performance accuracy of 91% for training and 87% for independent tests. Feature importance analysis revealed that inclined pull-ups, standing broad jump, shuttle run, 2.4 km run, age, and sit-ups were the most significant parameters. The Mann-Whitney test showed that the EFR group outperformed the AFR group in all anthro-fitness parameters except for height, weight, and age, which showed no significant difference. This study highlights the critical role of specific fitness and anthropometric parameters in distinguishing high-performing firefighters. By identifying the most significant contributors to overall fitness, fire departments can better prepare their personnel to meet the increasing public safety demands. The high accuracy of the predictive model also suggests its potential application in ongoing firefighter assessments and training optimization.

Authors: Gaikwad Shilpa , Kothari Sonali 
Published: February 2025

Abstract
This research aims to find an economical, non-invasive solution for grading apples by sweetness based on multispectral imaging. This paper examines the relationship between sugar levels and multispectral images of apple fruit taken inside a wooden multispectral imaging enclosure specially designed for taking apple pictures. In addition, using a hand-held refractometer, the sugar content of different apple samples and their corresponding multispectral images are collected. The methodology includes designing and building a prototype camera chamber, gathering pictures of various apples, and using advanced image analysis software to process the data. Prediction of outcomes: Building a practical grading system based on non-invasive multispectral imaging and finding a significant spectral feature of Apple fruit's sweetness levels in the project's range of concern. The proposed system implemented AppleNet, a convolutional neural network (CNN) within MATLAB, to process the multispectral images, and the accuracy achieved for grading the sweetness of apple fruit is 65%.
Reimagining the Mathematics Classroom through Magical Realism
Authors: Xenofontos Constantinos 
Published: February 2025

Abstract
This paper explores magical realism as a theoretical lens for analysing mathematics classrooms. Traditional frameworks often overlook the complexities of teaching and learning, focusing solely on measurable aspects. Inspired by magical realism – a literary genre blending the fantastical and the everyday – I propose a new perspective on how abstract mathematical concepts connect with students’ lived experiences. This approach values ambiguity emphasises productive struggle, and advocates for culturally responsive pedagogy. It challenges linear views of learning, recognising its non-linear, insight-driven nature. While conceptual, this framework offers potential for transforming classroom practices, though further empirical research is needed to examine its impact.
