In this paper‎, ‎we give the notions of crossed polymodule and cat$^1$-polygroup‎ ‎as a generalization of Loday's definition‎. ‎Then‎, ‎we define the pullback cat$^1$-polygroup and we obtain some results in this respect‎. ‎Specially‎, ‎we prove that by a pullback cat$^1$-polygroup we can obtain a cat$^1$-group‎.

introduction: open-apex teeth with irreversible pulpitis require complex and difficult treatment. providing the right environment for apexogenesis and pulp protection is vital for their long term prognosis. the young pulp of open apex tooth, however, is better equipped against irritation and assault. the aim of this study was to evaluate pulp inflammation in open apex canine teeth of cats. mate...

enhancement of antioxidant capacity of plants by natural antioxidants obtained from medicinal plants can be a simple way to produce stress tolerant plants. zataria multiflora essential oil (zo) is one of the useful antioxidants with potent antioxidant activity. zo is insoluble in water and can be degraded by light, oxygen, and high temperature. incorporation of zo into poly vinyl alcohol (pva) ...

background : the visceral larva migrans (vlm) is a syndrome observed in human infection with helminth larval eggs such as the toxocara spp. that usually infects dogs and cats. among the risk factors involved in the occurrence of vlm, partic­ularly importance of these animal populations, an investigation was carried out for the presence of toxocara spp. eggs in public parks in the city of urmia,...

cats play crucial roles in the epidemiology of toxoplasmosis. in the present study, a total of 198companion cats of different ages were examined for serum antibodies against toxoplasma gondii byimmunochromatography assay and for oocyst presence in faeces by microscopic examination (flotationmethod) and immunochromatography assay. the cats were selected between referred cases to the veterinary h...

This study primarily addresses the development of dynamic, selective and economical metal–acid (bifunctional) catalysts for one-pot menthol production by citral hydrogenation. Specifically, various metals such as Pd, Pt, Ni, Cs Sn were doped over alumina support. Additionally, bifunctional composite also prepared with impregnation heteropoly acids Pd precursors Analytical techniques (e.g., BET,...

We give conditions when cat(f × g) < cat(f) + cat(g). We apply our result to show that under suitable conditions for rational maps f , mcat(f) < cat(f) is equivalent to cat(f) = cat(f×idSn). Many examples with mcat(f) < cat(f) satisfying our conditions are constructed. We also resolve one open case of Ganea’s conjecture by constructing a space X such that cat(X × S1) = cat(X) = 2. In fact for e...

the aim of the present study was to determine the presence of helicobacter species in different parts of gastrointestinal tract, hepatobiliary system and pancreas of stray cats. six different sites at the level of genus, gastric (h. heilmannii and h. felis) and enterohepatic species of helicobacter were investigated in six cats using species-specific primers by polymerase chain reaction (pcr). ...

background: cats and other felines act as definitive hosts for many intestinal parasites, some of which are responsible for several zoonotic diseases.  the aim of this study was to determine the type and prevalence of protozoa and gastrointestinal helminthes among stray cats. methods: a cross sectional study was conducted. digestive tracts of 100 stray cats in zanjan province, north-west of ira...
