Optical Properties of Zirconium Doped Sodium-Boro-Zinc Fluoride Glasses

Effect of Zirconium doped sodium borate glasses with zinc fluoride and without zinc fluoride glasses were prepared individually by conventional melt quench method. All the Samples were analyzed using certain measurements like UV-Visible and Photoluminescence. UV-Visible spectra evidences that after 1mol% incorporation to glass matrix there exist 3F2-3P1 transition due to Zr2+ ions in both Zr:Zf glass series. Further; using Tauc's equation direct and indirect band gaps were estimated for all samples. Upon the excitation 365nm and 383nm the PL studies were carried out to know the possible transitions and the role of Zirconium in both glass series for the same CIE diagram was done

Automated ECG Analysis for Localizing Thrombus in Culprit Artery Using Rule Based Information Fuzzy Network.

Cardio-vascular diseases are one of the foremost causes of mortality in today’s world. The prognosis for cardiovascular diseases is usually done by ECG signal, which is a simple 12-lead Electrocardiogram (ECG) that gives complete information about the function of the heart including the amplitude and time interval of P-QRST-U segment. This article recommends a novel approach to identify the location of thrombus in culprit artery using the Information Fuzzy Network (IFN). Information Fuzzy Network, being a supervised machine learning technique, takes known evidences based on rules to create a predicted classification model with thrombus location obtained from the vast input ECG data. These rules are well-defined procedures for selecting hypothesis that best fits a set of observations. Results illustrate that the recommended approach yields an accurateness of 92.30%. This novel approach is shown to be a viable ECG analysis approach for identifying the culprit artery and thus localizing the thrombus

Effect of calcium channel blocker as anticonvulsant and its potentiating effect when used along with sodium valproate in pentylenetetrazole induced seizures in Albino rats

Background: Many antiepileptic drugs were introduced for the treatment of epilepsy. Ideal antiepileptic drug should not only prevent but also correct the underlying pathophysiology without altering the normal neurotransmission. Calcium channel blockers may form such group because initiation of seizure is associated intrinsic burst firing which is triggered by large inward calcium current, so this study was done to evaluate the anticonvulsant effect of amlodipine in albino rats.Methods: A total of 42 adult albino rats were included in the study and divided into 7 groups, each containing 6 rats. Group 1 received distilled water, group 2,3 received sodium valproate 50mg/kg and 100mg/kg, group 4-6 received amlodipine 1, 2, 4mg/kg and group 7 received combination of Amlodipine 1 mg/kg and sodium valproate 50mg/kg. Pentylenetetrazole induced seizures model was done and onset of myoclonic jerks, onset of clonic convulsions and duration of clonic convulsions was studied.Results: There was a significant anticonvulsant effect in Amlodipine doses 2, 4mg/kg (p <0.001). The combination of Amlodipine (1mg/kg) and Sodium valproate (50mg/kg) also had significant anticonvulsant effect.Conclusions: Amlodipine, a calcium channel blocker has anticonvulsant effect and also potentiated the anticonvulsant effect of low dose sodium valproate

Yield Gap Analysis in Adoption of Production Technology of Mango by the Farmers

The study was conducted on yield gap analysis in adoption of production technology of mango by the farmers at Tumkuru district. Ten villages were selected and out of which twenty farmers were selected from each for the study, ten belong to big and small farmers category. Total 200 sample size were selected, the data were collected through personal interview, Frontline demonstration, Off-campus and On-campus training programme. Observation was recorded that 20 per cent of yield gap between demonstration plot and actual farmers plot in mango. The total yield gap between potential yield and actual yield was 50%. Majority of the big farmers (63%) and small farmers (50%) were at medium level of adoption. Majority of the big farmers (more than 80%) fully adopted the production practices like plant population per hectare and pit size, whereas more than 90 per cent of small and big farmers have not adopted production technology such as spraying with mango special as micronutrient, application of Paclobutrazol for regular bearing in Alphanso mango variety and using improved mango harvester for drudgery reduction. Significantly adopted by the big farmers in production technologies such as recommended farm yard manure application (55%), recommended quantity (730:180:680 NPK g/plant/year) of inorganic fertilizer application (58%) and powdery mildew management (46%). More than 70 per cent of small farmers have not adopted technologies such as selection of grafted seedlings (71%) and fruit fly management (70%). But significantly not adopted by the small farmers in production technology viz., selection of improved variety (62%), selection of grafted seedlings (71%), recommended quantity (730:180:680 NPK g/plant/year) of inorganic fertilizer application (72%) and powdery mildew management (63%). High cost and inadequate availability of labour, erratic supply of electricity, lack of knowledge regarding pest and disease management, unawareness about nutrient management and high cost of inputs were the major production constraints perceived by the Mango growers. A great majority of big and small farmers opined that providing crop insurance, availability and supply of improved seedlings and inputs at right time, research efforts for development of cost effective simple technologies for pest and disease management and conducting demonstration cum training programmes were necessary to overcome the constraints
