A survey on the question of how well veterinarians are prepared to predict their client's human-animal bond
Authors: Catanzaro Thomas E. 
Published: February 2025

Summary
In a survey of 63 military veterinary facilities, actual responses from 961 clients were compared with 86 servicing US Army Veterinary Corps practitioners' predictions of the clients' responses. The survey questions were designed to evaluate the degree of human-animal bonding of the military clients. The survey revealed that the effects of human-animal interaction on community, family, and animal health have extensive impact on the military member, the military installation, and the military health care delivery system. Results revealed sociologic and psychologic factors that influenced the quality of life of mobile military members and their families. The survey also revealed that although the newly graduated veterinarians understood (he professional and scientific values of their clients, they often underestimated the social interdependence between client and pet. The military veterinarians in this survey were considered to be representative of the new graduate, and the results are relevant to any civilian practitioner concerned with client relations or hiring new graduates.

Authors: Memon Mushtaq A. , Dawson Lionel J. , Usenik Edward A. , Rice Lawrence E. 
Published: February 2025

Summary
One hundred seventy-two bulls with preputial injuries were treated from 1980 through 1985. Most of the injuries developed during the breeding season (April through August), with a peak during June. The number (111) of bulls represented by 3 beef breeds (Brangus, Brahman, Beefmaster) was greater than the number (61) of the other 9 breeds included in the survey. Preputial prolapse (pp) and posthitis without obvious laceration was diagnosed in 82 of 172 bulls. Preputial laceration, abscessation, stricture with phimosis, and pp with penile hematoma were diagnosed in 46, 22, 15, and 9 bulls, respectively. These abnormalities were treated medically and/or surgically. Questionnaires (n = 145) were mailed, and 83 (57.4%) replies were received. Owners (80/83) of affected bulls responded to questions regarding the future use of their bulls for breeding. Of the bulls with pp and posthitis (n = 34), laceration (n = 17), abscessation (n = 15), stricture with phimosis (n = 8) and pp with penile hematoma (n = 6) and treated medically and/or surgically, 30, 11, 7, 7, and 4 bulls, respectively, (74% overall) were returned to breeding use successjully.
Keratomas in horses: Seven cases (1975–1986)
Authors: Lloyd K. C. Kent , Peterson P. Robin , Wheat John D. , Ryan Ann E. , Clark James H. 
Published: February 2025

Summary
The diagnosis of keratoma in 7 horses and their treatment and outcome were evaluated. Horses were 2 to 20 years old, of various breeds, and were intact or castrated males. All were lame, and 6 horses had had previous injuries of the affected hoof that had not responded to prior treatments. Only 1 hoof was affected in each horse. Keratomas were beneath the hoof wall (6 horses) or sole (1 horse). Radiographically, a circular or semicircular defect with a discrete margin was present in the distal portion of the third phalanx in 3 horses. Grossly, keratomas were firm solitary masses (1.5 to 5 cm diameter); gray, tan, or yellow; and oval or conical. Keratomas were excised from beneath the hoof wall by removing a section of hoof wall (5 horses) or by undermining the wall beginning at its junction with the sole (1 horse). A keratoma beneath the sole in 1 horse was excised by excavating the sole to the level of the palmar surface of the third phalanx. Keratoma was verified microscopically by the presence of characteristic rings of squamous epithelial cells with abundant keratin. Purulent exudate and inflammatory infiltrate often were present concurrently, reflecting an associated localized infection. Aftercare included daily application of an antiseptic iodine solution and foot bandages, and shoeing with a treatment plate several weeks after surgery. Hoof and sole defects healed completely between 6 months and 1 year. By 1 year after surgery, 6 horses were sound, and keratoma had not recurred.
Inheritance of associated ocular and skeletal dysplasia in Labrador Retrievers
Authors: Carrig C. B. , Sponenberg D. P. , Schmidt G. M. , Tvedten H. W. 
Published: February 2025

Summary
A breeding colony was established to investigate the inheritance of associated ocular and skeletal dysplasia in Labrador Retrievers; 124 pups were produced. These pups were evaluated for the presence of ocular lesions, including cataracts, vitreous strands, persistent hyaloid remnants, retinal folds, retinal dysplasia, peripapillary hyperreflectivity, and rhegmatogenous retinal detachments, and skeletal abnormality, which was recognized by shorter than normal forelimbs and an abnormal morphologic appearance of the radius and ulna.
Analysis of the distribution of lesions in pups indicated that the syndrome is caused by one abnormal gene, which has recessive effects on the skeleton and incompletely dominant effects on the eye. This would suggest that suspect carrier dogs could be identified by test matings with a known homozygote.

SUMMARY
Two hundred ten dogs that had primary lung tumors diagnosed between 1975 and 1985 were evaluated. The majority of the tumors were classified as adenocarcinoma (74.8%) and alveolar carcinoma (20%). The most common clinical signs of disease were cough (52%), dyspnea (23.8%), lethargy (18.1%), weight loss (12.4%), and tachypnea (4.8%). The clinical methods that were most successful in directly or indirectly leading to a diagnosis of primary lung tumor were thoracic radiography (77.1%) and cytologic examination of fine-needle aspirate specimens (24.8%).

Authors: Mourad Dler , Goymen Merve , Uzuner Fatma Deniz , Onal Tuna , Tuglu Mehmet Ibrahim 
Published: February 2025

Abstract

Objective
The aim of this study was to evaluate the effects of high molecular weight hyaluronic acid (HMWHA) and low molecular weight hyaluronic acid (LMWHA) on alveolar bone remodelling during orthodontic tooth movement (OTM).

Materials and methods
The study involved 60 Wistar-Albino rats, divided into two main groups and further divided based on time periods (1, 3, 7, 14, and 21 days) therefore containing 6 rats in each subgroup. Orthodontic mesialisation of the maxillary first molars was bilaterally achieved using nickel-titanium closed coil springs. In Group I, the right side was injected with HMWHA, while in Group II, the right side was injected with LMWHA. The left side of all rats was injected with normal saline. OTM was measured using 3-dimensional digital models. Alveolar bone volume in the interradicular areas of the first molars was evaluated through histomorphometric and immunohistochemical analyses of receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG).

Results
Histologically, on days 14 and 21, the number of osteoclasts on the experimental sides was higher than on the control sides in both groups. On day 21, the amount of OTM in the HMWHA-injected group was 1.4 times greater than in the control group. Both types of hyaluronic acid increased the RANKL/OPG ratio.

Conclusion
The injection of HA may accelerate orthodontic tooth movement by decreasing alveolar bone density and enhancing bone cell proliferation.
Negative clean rings
Authors: Călugăreanu Grigore , Pop Horia F. 
Published: February 2025

Abstract
A ring is called negative clean if the negative (i.e., the additive inverse) of each clean element is also clean. Clean rings are negative clean.
In this paper, we develop the theory of the negative rings, with special emphasis on finding the clean matrices which have (or have not) clean negatives. Many explicit results are proved for 2 × 2 matrices and some hard to solve quadratic Diophantive equations are displayed.
Characterization of second type plane foliations using Newton polygons
Authors: Fernández-Sánchez Percy , García barroso Evelia R. , Saravia-Molina Nancy 
Published: February 2025

Abstract
In this article we characterize the foliations that have the same Newton polygon that their union of formal separatrices, they are the foliations called of the second type. In the case of cuspidal foliations studied by Loray [Lo], we precise this characterization using the Poincaré-Hopf index. This index also characterizes the cuspidal foliations having the same process of singularity reduction that the union of its separatrices. Finally we give necessary and sufficient conditions when these cuspidal foliations are generalized curves, and a characterization when they have only one separatrix.
A result of instability for two-temperatures Cosserat bodies
Authors: Marin M. , Vlase S. , Fudulu I.M. 
Published: February 2025

Abstract
In our study we consider a generalized thermoelasticity theory based on a heat conduction equation in micropolar bodies. Specifically, the heat conduction depends on two distinct temperatures, the conductive temperature and the thermodynamic temperature. In our analysis, the difference between the two temperatures is clear and is highlighted by the heat supply. After we formulate the mixed initial boundary value problem defined in this context, we prove the uniqueness of a solution corresponding some specific initial data and boundary conditions. Also, if the initial energy is negative or null, we prove that the solutions of the mixed problem are exponentially instable.
Algebraic Heun Operators with Tetrahedral Monodromy
Authors: Pleşca Iulia-Cătălina 
Published: February 2025

Abstract
Our work adds to the picture of second order differential operators with a full set of algebraic solutions, which we will call algebraic. We see algebraic Heun operators as pull-backs of algebraic hypergeometric operators via Belyi functions. We focus on the case when the hypergeometric one has a tetrahedral monodromy group. We find arithmetic conditions for the pull-back functions to exist. For each distribution of the singular points in the ramified fibers, we identify the minimal values of the exponent differences and we explicitly construct the dessin d’enfant corresponding to the pull-back function in the minimal cases. Then by allowing some parameters to vary, we find infinite families of such graphs, hence of Heun operators with tetrahedral monodromy.
On the three-spliced Exponential-Lognormal-Pareto distribution
Authors: Bâcă Adrian , Vernic Raluca 
Published: February 2025

Abstract
To model statistical data coming from two di erent distributions, Cooray and Ananda [1] introduced a composite (two-spliced) Lognormal-Pareto model, that was further extended by Scollnik [9] and fitted to insurance data. Inspired by these studies, more general three-spliced composite models are considered in this work, built by joining three di erent distributions. In particular, the study is focused on the three-spliced Exponential-Lognormal-Pareto distribution. The main characteristics of this model, as well as statistical inference are discussed. The parameters estimation is illustrated on random generated data.

Authors: Dutta Hemen , Kumar B.V. Senthil , Sabarinathan S. 
Published: February 2025

Abstract
The advantage of various fuzzy normed spaces is to analyse impreciseness and ambiguity that arise in modelling problems. In this paper, various classical stabilities of a new hexic functional equation in di erent fuzzy spaces like fuzzy Banach space, Felbin’s fuzzy Banach space and intuitionistic fuzzy Banach space are presented, concerning the Ulam’s theory of stabilities of equations. To validate the stability results, experimental results are presented. Also, a comparative study of the results obtained in this investigation are provided.

Authors: Leahu Alexei , Andrievschi-Bagrin Veronica , Ciorbă Dumitru , Fiodorov Ion 
Published: February 2025

Abstract
In our paper we describe the corresponding dynamic mathematical models to perform a comparative analysis of the reliability of two types of networks: serial-parallel and parallel-serial when the number of subnetworks is constant and the numbers of units in each sub-network are Power Series Distributed (PSD) random variables (r.v.), but also when the lifetimes are independent, identically distributed r.v. We shows that the lifetime distributions of such kind of networks leads us to two new families of distributions called Min(Max-PSD) and Max(Min-PSD) distributions. The formulas for calculating the reliability of the related networks it was deduced too. Su cient conditions have been formulated for the serial-parallel network to always be more reliable than the parallel-serial network. Some graphically illustrated examples have been provided.

On some links between the generalised Lucas pseudoprimes of level k
Authors: Andrica Dorin , Bagdasar Ovidiu , Rassias Michael Th. 
Published: February 2025

Abstract
Pseudoprimes are composite integers sharing behaviours of the prime numbers, often used in practical applications like public-key cryptography. Many pseudoprimality notions known in the literature are defined by recurrent sequences. In this paper we first establish new arithmetic properties of the generalized Lucas and Pell-Lucas sequences. Then we study the recent notion of generalized Pell and Pell-Lucas pseudo-primes of level k, and find inclusions between the sets of pseudoprimes on different levels. In this process we extend several results concerning Fibonacci, Lucas, Pell, and Pell-Lucas sequences.

m,n
. The problem is completely solved except for the case n<r ∈{2m +2, 2m +3}, which is solved under certain assumptions. It enables us to determine in particular the dynamic chromatic number concerning this problem, for all r ≤ 7, and also, for all m ∈{1, 2}.

Authors: Koohnavard Roghayeh , Saeid Arsham Borumand 
Published: February 2025

Abstract
In this paper, we define modal operators in residuated skew lattices and prove some fundamental properties of monotone modal operators on residuated skew lattices (RSL). We prove that the composition of two modal operators is a modal operator if and only if they commute. We investigate strong modal operators in RSL and get a characterization of them. Deductive systems under a modal operator are investigated.
On the torsional energy of torus knots under infinitesimal bending
Authors: Maksimović Miroslav D. , Rančić Svetozar R. , Najdanović Marija S. , Velimirović Ljubica S. , Ljajko Eugen S. 
Published: February 2025

Abstract
The article deals with the infinitesimal bending theory application to the knots theory. The impact of infinitesimal bending on the torsional energy at torus knots is considered, and the results show that it is not stationary under infinitesimal bending. The torsional energy variation is determined as well. We prove that there is no infinitesimal bending field that leaves torus curves on the torus. Besides, we define an infinitesimal bending field that does not tear the torus knots while bending. Having in mind the importance of visualization in the infinitesimal bending theory, we observed infinitesimal bending of a curve in that field using independently developed software. The graphs we obtained are presented in the paper and the torus knots are coloured according to their torsional energy. We calculated the numerical value of torsional energy under infinitesimal bending and, finally, the results are discussed using convenient specific examples.
The eigenspaces of twisted polynomials over cyclic field extensions
Authors: Owen Adam , Pumplün Susanne 
Published: February 2025

Abstract
Let K be a field and σ an automorphism of K of order n. Employing a nonassociative algebra, we study the eigenspace of a bounded skew polynomial f ∈ K[t; σ]. We mainly treat the case that K/F is a cyclic field extension of degree n with Galois group generated by σ.We obtain lower bounds on the dimension of the eigenspace, and compute it in special cases as a quotient algebra. Conditions under which a monic polynomial f ∈ F [t] ⊂ K[t; σ] is reducible are obtained in special cases.

Published: February 2025

Abstract
The pandemic has represented an extraordinary time similar to natural calamities that radically transformed the way of society had to function. Freedom of movement but also physical proximity were restricted, proportional to the danger to the health of the population. In this context, solutions had to be established for the continuation of public and social activities. Therefore, certain fields of activity have been favored by the evolution of information technology, transferring to the online environment. The objective of the research is to identify the problems that emerged in the online teaching activity, during the Covid-19 Pandemic, which were the methods applied by the teaching sta for teaching and whether the students were able to participate and understand the notions taught in the online activity. The test t-Student and U-Mann-Whitney test were used to identify differences in the study of the impact of the Covid 19 pandemic in online education in schools in preuniversitary level.

In this paper we analyze strongly 2-absorbing prime ideals (shortly strongly 2-API), strongly 2-absorbing weak prime ideals (shortly strongly 2-AWPI) and 2-absorbing weak prime ideals (shortly 2-AWPI) in a non-commutative ring, which represent generalization of prime ideals (shortly PI) in a non-commutative ring. The relationship between the strongly 2-API and the 2-absorbing prime ideal (shortly 2-API) is examined. We provide examples to illustrate the new concept of strongly m
