    A graph G=(V,E) with p vertices and q edges is said to be a mean graph if it is possible to label the vertices with distinct elements f(x) from 0,1,2,…..q in such a way that when each edge is labelled with if is even and if is odd, then the resulting edge labels are distinct. is called a mean labelling of G. In this paper, we investigate the mean labelling of caterpillar, dragon, arbitrary super subdivision of a path and some graphs which are obtained from cycles and stars

    In this talk, we will work almost exclusively with the Euler characteristic and some of the consequences of its topological invariance. We discuss by following that motivated the study of the characteristic. This gives a relation between topological invariant of the surface and a quantity derived from its combinatorial description. Secondly, we obtain an inequality relating the number of normal triangles and normal quadrilaterals, that depends on the maximum number of tetrahedrons that share a vertex. In this thesis, we disscuss this and related injectivity conditions and show that there are many rings

    A field experiment was conducted during 2005-07 at Indian Institute of Horticultural Research, Bangalore, on papaya cv. Surya with six organic treatments along with recommended dose of fertilizers and no manure/fertilizer application. Results indicated that crop growth and fruit yield were higher in inorganic fertilizer treatment (55 t ha1) compared to organic treatments (26.9 to 38 t ha-1). There was no significant variation in average fruit weight and TSS, but shelf life of the fruit was significantly higher in organic treatments (6.2 to 7.9 days) as compared to inorganic fertilizer treatment (5.1days). Among the treatments, application of 7 kg urban compost plant-1 or 10 kg FYM plant-1 was found to be ideal for improving soil health in terms of microbial population, and biochemical reaction compared to other treatments

    Differential expression of gga-miR-142-3p microRNA of haemopoeitic origin during immune organ development and functional stages in chicken embryos creates new opportunities for understanding its pivotal role during embryonic developmental stages. To decipher the role of gga-miR-142-3p in-ovo knockdown was carried out with LNA modified anti-miR-gga-miR-142-3p via intravenous route at developmental and functional stages of the immune organs and other organs. Bioinformatic analysis of the genes targeted by gga-miRNA-142-3p revealed that the predicted gene XPO1 conserved binding sites at 3’UTR. The target gene XPO1 was evaluated as the validated target of gga-miR-142-3p by employing qPCR SYBR green based technology, which was evidenced by its increased expression in the tissues of gga-miR-142-3p knockdown chicken embryos. Histopathological alterations in the immune organs and visceral organs indicated that the systemic knockdown of gga-miR-124-3p led to over expression of the XPO1 gene during the embryonic stages, and changed the environment of the immune organs related to structural integrity, immune response, signal transduction and migration of B and T cells during the embryonic developmental stage in the chicken embryos. The results clearly indicated that these changes could alter the postnatal development and functions of these immune organs, and may lead to development of immuno-compromised chickens.Različita ekspresija gga-miR-142-3p mikroRNA hemopoetskog podrijetla daje nove mogućnosti razumijevanja njezine ključne uloge u embrionalnom razvoju limfnih organa i funkcionalnih zbivanja u pilećem zametku. Za otkrivanje uloge gga-miR-142-3p in ovo provedeno je utišavanje zaključanom nukleinskom kiselinom što preko anti-miR-gga-miR-142-3p preinačuje razvojne i funkcionalne sposobnosti limfnih i drugih organa. Bioinformatička analiza ciljnih gena za gga-miRNA-142-3p otkriva da gen XPO1 ima konzervirana mjesta vezanja na 3’UTR. Gen XPO1 bio je potvrđen kao cilj za gga-miR-142-3p uporabom tehnologije temeljene na qPCR SYBR zelenilu, što je bilo dokazano njegovom povećanom ekspresijom u tkivima pilećih zametaka s utišanim gga-miR-142-3p. Patohistološke promjene u imunosnim i unutarnjim organima pokazuju da sustavno utišavanje gga-miR-124-3p vodi do prevelike ekspresije gena XPO1 tijekom embrionalnog razvoja. To mijenja zadaću imunosnih organa s obzirom na strukturni integritet, imunosni odgovor, prijenos poruka te migraciju B i T limfocita tijekom razvoja pilećih zametaka. Rezultati jasno naznačuju da te promjene mogu preinačiti postnatalni razvoj i funkcije imunosnih organa te mogu dovesti do razvoja imunološki oslabljenih pilića

    A field trial on organic practices in papaya cv. Surya was conducted during 2009-2011 with 10 nutrient combinations involving farm yard manure, biofertilizers and VAM along with 100% recommended dose of fertilizers and no manure/ fertilizer treatment. Vegetative parameters were recorded periodically. At 18 months after planting, plant height, plant girth and number of leaves were found to be significant. Results indicated that, crop growth was better with organic treatments compared to no manure/fertilizer treatment. Fruit yield and quality parameters were also recorded. Fruit yield and average fruit weight were found to be significant. Maximum fruit yield of 32kg/plant (80 t/ ha) was recorded under 75% recommended dose of fertilizer applied as farm yard manure+vermicompost, which was significantly superior to that in 100% recommended dose of fertilizer for the 18-month cropping period

    A field experiment was conducted during 2009-10 at Indian Institute of Horticultural Research, Bangalore using papaya cv. 'Surya'. Ten organic nutrient treatments along with recommended dose of fertilizers and control (no manure/fertilizer) were used totaling twelve treatment combinations of FYM, biofertilizers and vermicompost. Fruit quality parameters such as total carotenoids, lycopene, TSS, average fruit weight and ascorbic acid content were analyzed. Among the treatments, application of 50% recommended dose of fertilizers in the form of farm yard manure (FYM) applied as Azospirillum+Phosphate solubilizing bacteria+Mycorrhiza+Vermicompost showed high level of carotenoids, lycopene and low levels of ascorbic acid. TSS and average fruit weight were not affected by various organic nutrient treatments

    <b>Background: </b> Snoring is a common problem that poses a high risk for obstructive sleep apnea (OSA). We studied the contribution of risk factors for OSA in snorers referred for full-night polysomnography (PSG). <b> Methods: </b> A questionnaire was administered to subjects referred for PSG in the period from April 2002 to March 2005. <b> Results: </b> There were 191 (84&#x0025;) snorers identified by 227 PSG studies. They had a mean age of 48.1&#x00B1;9.8 years, (age range, 23-73 years) and 78.5&#x0025; were males. OSA as indicated by a respiratory disturbance index (RDI) of&#62; 5 events/hour was seen in 126 (66&#x0025;) subjects. In males, 72.7&#x0025; had OSA, with a mean RDI of 43.0&#x00B1;26 events/hour, versus 39&#x0025; with OSA in females with a mean RDI of 27.8&#x00B1;26.5 events/hour (P&#60; 0.001). The OSA group had a higher mean Epworth Sleepiness Scale (ESS) (P&#60; 0.001), a larger mean neck circumference (P&#60; 0.01), an increased mean age (P&#60; 0.05), and more witnessed apneas (P&#60; 0.001) but not choking (P=0.096). The mean increase in body mass index was linked to OSA only in females (P&#60; 0.05) but not in the overall study (P=0.507). Multivariate analysis showed that ESS, male gender, and a history of witnessed apnea were associated with OSA, while controlling for obesity, large neck circumference, age, and history of choking. <b> Conclusion: </b> In screening snorers for PSG, male gender, ESS and a history of witnessed apneas were the most important predictors of OSA, but other factors should be considered in referring snorers for PSG. In males, obesity did not contribute to the risk of OSA in our study population

    Semiconducting nanoparticles with luminescent properties are used as detection probes and drug carriers in in-vitro and in-vivo analysis. ZnO nanoparticles, due to its biocompatibility and low cost, have shown potential application in bioimaging and drug delivery. Thus, ZnO/SiO2 core/shell nanoparticle was synthesised by wet chemical method for fluorescent probing and drug delivery application. The synthesised core/shell nanomaterial was characterized using XRD, FTIR, UV-VIS spectroscopy, Raman spectroscopy, TEM and PL analysis. The silicon shell enhances the photoluminescence and aqueous stability of the pure ZnO nanoparticles. The porous surface of the shell acts as a carrier for sustained release of curcumin. The synthesized core/shell particle shows high cell viability, hemocompatibility and promising florescent property. [Figure not available: see fulltext.]
