Management of Reproduction on Small, Medium and Large Rabbit Farms: A Review
Szendro, Zs.,Szendro, K.,Zotte, A. Dalle Asian Australasian Association of Animal Productio 2012 Animal Bioscience Vol.25 No.5
One of the main goals of small, medium and large farms is to improve the reproductive performance of rabbit does. Stocks of lower productivity can be improved by crossing with intensive breeds. A better nutritional status of both foetuses and suckling kits has a positive effect on their later productivity. Overfeeding young females before first mating can lead to conditions of fattiness. Using restricted feeding or higher fibre content in the feed and changing it for a higher level ad libitum feeding about one week prior to first mating leads to longer lifespan and higher productive level. Intensive reproductive rhythm creates a negative energy balance in does : they are unable to consume enough feed (energy) for the nutritional requirements of foetus and lactation, and therefore lose most of their fat reserves. Furthermore, primiparous does also expend energy because they are still growing. Under intensive conditions, the 42-d reproductive rhythm (re-mating 11 days after parturition) is recommended. Under extensive conditions, the 18 or 25-d mating interval with 35 to 42-d weaning could be suitable. On small farms, natural mating is favoured; on large farms AI is commonly employed. The main advantage of AI is the all-in, all-out system. Hormonal (PMSG) treatment is used with AI to increase receptivity on d 11. Frequent and high level PMSG use can lead to higher anti-PMSG antibody rates. Lower level (max. 20 IU) and less frequent PMSG injection or non-hormonal alternative methods (short dam-litter separation, changing nursing method or lighting programs) are recommended for this reason.

Moire superlattices in strained graphene-gold hybrid nanostructures
Palinkas, A.,Sule, P.,Szendro, M.,Molnar, G.,Hwang, C.,Biro, L.P.,Osvath, Z. Pergamon Press ; Elsevier Science Ltd 2016 Carbon Vol.107 No.-
<P>Graphene-metal nanoparticle hybrid materials potentially display not only the unique properties of metal nanoparticles and those of graphene, but also additional novel properties due to the interaction between graphene and nanoparticles. This study shows that gold nanoislands can be used to tailor the local electronic properties of graphene. Graphene on crystalline gold nanoislands exhibits moire superlattices, which generate secondary Dirac points in the local density of states. Conversely, the graphene covered gold regions undergo a polycrystalline -> Au (111) phase transition upon annealing. Moreover, the nanoscale coexistence of moire superlattices with different moire periodicities has also been revealed. Several of these moire periodicities are anomalously large, which cannot be explained by the standard lattice mismatch between the graphene and the topmost Au (111) layers. Density functional theory and molecular dynamics simulations show for the first time that in such cases the graphene and the interfacial metallic layer is strained, leading to distorted lattice constants, and consequently to reduced misfit. Room temperature charge localization induced by a large wavelength moire pattern is also observed by scanning tunneling spectroscopy. These findings can open a route towards the strain engineering of graphene/metal interfaces with various moire superlattices and tailored electronic properties for nanoscale information coding.

Development of new immunosensors for determination of contaminants in food
Nora Adanyi,Maria Varadi,김남수,Istvan Szendro 한국물리학회 2006 Current Applied Physics Vol.6 No.2
This article compares two dierent immunosensors developed for important food analytical and environmental problems. Thelightmode spectroscopy (OWLS).Immobilizing anti-Escherichia coliIgG onto the gold electrode of QCM,E. colibacterial cells were measured. Resonant fre-quency responses of the sensor system were determined at various concentrations ofE. coli(1.7· 1058.7· 107 CFU/ml). The sameantibody was immobilized onto the amino silanized sensor of OWLS by glutaraldehyde covalent coupling. The measuring range wasbetween 3· 104 and 3 · 107 CFU/ml.Chloramphenicol (CAP) antibiotic was measured in standard solutions with immunosensor based on label-free techniques tostudy the possibility of direct sensing of molecules with low molecular weight. Anti-chloramphenicol antibody immobilization havebeen performed onto the gold surface of the crystal by using 3-mercaptopropionic acid (MPA) and dimethylaminopropyl-ethylcar-bodiimidehydroxysuccinimide ester (EDC-NHS) chemistry. The linear measuring range was found between 5· 10. 6 and5 · 10. 2 M chloramphenicol. Experiments were performed for measuring chloramphenicol with the same method with OWLSdetection. After glutaraldehyde cross-linker immobilized the antibody, the signal measured was proportional to the analyte contentin the range of 10. 710. 3 M.
