Social Multimedia Networks Behaviour Model & Architecture

People constantly use social multimedianetworks to communicate with one another, with usersmostly sharing data, such as photos and videos. Weexamine the motivations that drive colluders to formalliances over social networking platforms anddetermine how these groups create coalitions toadvance their interests. We also investigate thenetwork architectures that underlie social multimedianetworks and how these platforms circulate. Sucharchitectures are connected to different protocols,including WebID, Semantic Pingback andPubSubHubbub, to form a logical semantic circulatingsocial multimedia network that delivers a centralisedsocial network structure

Response of Beet Root Tubers to Gypsum, P Levels, Boron and Iron Sulphate in Salt-Affected Soils

A field-experiment was conducted in salt-affected soils of Dodda Seebi tank command area of Tumkur district, Karnataka during rabi season of 2007 to study effect of gypsum, P level, borax and iron sulphate on beet root tuber yield and nutrient uptake. Treatments included two main-plot treatments, viz., M0: Control (without gypsum) and M1: gypsum application @ 9.0 t ha-1 and eight sub-plot treatments, viz., S1: Phosphorus @ 100 kg P2O5 ha-1, S2: Phosphorus @ 150 kg P2O5 ha-1, S3: S1 + Borax @ 5 kg ha-1, S4: S2 + Borax @ 5 kg ha-1, S5: S1 + FeSO5 @ 25 kg ha-1, S6: S2 + FeSO4 @ 25 kg ha-1, S7: S3 + FeSO4 @ 25 kg ha-1 and S8: S4 + FeSO4 @ 25 kg ha-1. Recommended N and K were applied to all treatments. The experiment was laid out in split plot design with three replications. Beet root, a salt-tolerant crop, was sown for testing its performance in salt-affected soils. Significantly higher tuber yield of 12.70 t ha-1 was realized when the crop received gypsum @ 9.0 t ha-1 compared to control (7.73 t ha-1), besides higher nutrient uptake by the tubers. Among the nutrients, application of P at higher level (150 kg P2O5 ha-1) plus recommended NK along with borax and iron sulphate realized higher tuber yield (15.72 t ha-1) as well as nutrients uptake by tubers. Crop that received gypsum in combination with P at a higher level plus recommended NK, along with borax and iron sulphate, resulted in highest tuber yield (19.72 t ha-1) and nutrient uptake

Genetic diversity study in tropical carrot (Daucus carota L.)

Genetic diversity study was conducted at ICAR- Indian institute of Horticultural Research, Bengaluru during 2018-19. In this study, 80 accessions were evaluated for 16 yield and yield attributing traits. The Mahalanobis’ D2 analysis grouped these accessions into seven clusters. Cluster I was the largest with 69 genotypes followed by cluster III comprising six genotypes while, the clusters II, IV, V, VI and VII contained one genotype each. Among the traits studied, yield contributed maximum (38.04 %) towards diversity, followed by root weight (26.58%), root color (9.18%) and plant height (6.7%). As far as root weight (g) [d1], leaf weight (g), root weight (g), number of leaves, TSS(°Brix), leaf weight (g), root diameter (mm), core diameter (mm), and root cracking are concerned, they contributed 3.45, 2.09, 1.77, 1.71, 1.55, 1.52, 1.46, 1.33, 1.01 and 0.82 percent respectively. Diversity analysis has given an indication about the genetic variation among the carrot accessions which will prove useful in selection of diverse parents in crop improvement programme

Rhinacanthus nasutus

The present study was conducted to evaluate the therapeutic efficacy of Rhinacanthus nasutus (R. nasutus) on mitochondrial and cytosolic enzymes in streptozotocin-induced diabetic rats. The rats were divided into five groups with 6 rats in each group. The methanolic extract of R. nasutus was orally administered at a dose of 200 mg/kg/day, and glibenclamide was administered at a dose of 50 mg/kg/day. All animals were treated for 30 days and were sacrificed. The activities of both intra- and extramitochondrial enzymes including glucose-6-phosphate dehydrogenase (G6PDH), succinate dehydrogenase (SDH), glutamate dehydrogenase (GDH), and lactate dehydrogenase (LDH) were measured in the livers of the animals. The levels of G6PDH, SDH, and GDH were significantly reduced in the diabetic rats but were significantly increased after 30 days of R. nasutus treatment. The increased LDH level in diabetic rats exhibited a significant reduction after treatment with R. nasutus. These results indicate that the administration of R. nasutus altered the activities of oxidative enzymes in a positive manner, indicating that R. nasutus improves mitochondrial energy production. Our data suggest that R. nasutus should be further explored for its role in the treatment of diabetes mellitus

Prevalence of thyroid dysfunction in women with abnormal uterine bleeding in reproductive age

Background: Abnormal uterine bleeding (AUB) is one of the commonest presentations encountered in gynecological outpatient department. Menstruation is also regulated by many mechanisms, including thyroid hormone. So, for definitive management of AUB, it becomes imperative to assess thyroid status in those with abnormal uterine bleeding.Methods: Cross sectional study was conducted on all woman attending to OPD at Sri Siddhartha Medical College, Tumukuru, with complaints of abnormal uterine bleeding (AUB). Thyroid test was done for those who were eligible under inclusion criteria. Incidence of thyroid disorders among AUB and type of abnormal menstrual pattern associated with specific type of thyroid dysfunction were noted in this study.Results: Total of 522 presented with AUB. AUB was most common among woman age >40 years at 49.23% (257 of total 522 cases). AUB was more common in Multipara at 61.49% (321 of 522 cases). Menorrhagia was commonest pattern in AUB accounting for 51.34% (268 of 522cases). Thyroid dysfunction was present in 12.27% (64 of 522) of cases with AUB. Among them hypothyroid was most common accounting for 8.81% (46 of 522 cases). Hyperthyroidism was present in 3.44% (18 of 522 cases). Menorrhagia was most common pattern in Hypothyroidism at 65.21% (30 of 46 cases, followed by polymenorrhea at 17.39% (8 of 46 cases). Oligomenorrhea was most common in hyperthyroid group at 55.54% (10 of 18 cases) closely followed by hypomenorrhea at 44.44% (8 of 18 cases).Conclusions: Abnormal uterine bleeding (AUB) is one of the commonest gynecological complaint at gynecological OPD.  Thyroid dysfunction is noted consistently in cases of AUB. So, evaluation of thyroid profile should be part of evaluation of AUB, especially during perimenopause

Enhanced photoluminescence of Gd 2O 3:Eu 3+ nanophosphors with alkali (M = Li +, Na +, K +) metal ion co-doping

Gd 1.95Eu 0.04M 0.01O 3 (M = Li +, Na +, K +) nanophosphors have been synthesized by a low temperature solution combustion (LSC) method. Powder X-ray diffraction pattern (PXRD), scanning electron microscopy (SEM), UV-vis and photoluminescence (PL) measurements were carried out to characterize their structural and luminescent properties. The excitation and emission spectra indicated that the phosphor could be well excited by UV light (243 nm) and emit red light about 612 nm. The effect of alkali co-dopant on PL properties has been examined. The results showed that incorporation of Li +, Na + and K + in to Gd 2O 3:Eu 3+ phosphor would lead to a remarkable increase of photoluminescence. The PL intensity of Gd 2O 3:Eu 3+ phosphor was improved evidently by co-doping with Li + ions whose radius is less than that of Gd 3+ and hardly with Na +, K + whose radius is larger than that of Gd 3+. The effect of co-dopants on enhanced luminescence was mainly regarded as the result of a suitable local distortion of crystal field surrounding the Eu 3+ activator. These results will play an important role in seeking some more effective co-dopants. © 2011 Elsevier B.V. All rights reserved
