Brown tumor in mandible as a first sign of vitamin D deficiency: A rare case report and review
No full textCentral giant cell granulomas (CGCGs) are uncommon but the most aggressive benign intraosseous tumors of jaws, with an unpredictable outcome. They account for less than 7% of all benign jaw lesions, with a female to male ratio of about 2:1. The classical "brown tumor" is commonly seen in the long bones, pelvis, and ribs. Facial bone involvement is rare and usually appears as solitary or multilocular soap bubble like radiolucencies. CGCGs are traditionally treated by both surgical and intralesional injection, with a variable recurrence rate. Here, we report a 12-year-old female patient with mandibular brown tumor as a first sign of secondary hyperthyroidism induced due to vitamin D deficiency and hypocalcemia
Stability of a 3-variable quadratic functional equation
No full textIn this paper, the authors discuss the general solution and the stability of a 3-variable quadratic
functional equation f(x+y,z+w,u+v)+ f(x-y,z-w,u-v)= 2f(x, z,u)+ 2f(y,w,v).
The quadratic form f (x,y,z)=ax2+by2+cz2+d xy+e yz+f zx is found to be the
solution of the above functional equatio
Assessment of Spatial Variability of Soil Properties Using Geospatial Techniques for Enhanced Productive Capacity of Agricultural Systems in India
No full textSoil is an important source of available nutrients. Either shortage or surplus of available nutrients in the soil would limit growth of crops. Understanding the spatial variability and distribution patterns of soil available nutrients is essential for soil management with respect to fertilizer application. A total of 111 geo-referenced soil samples were collected on 300 m x 300 m grid at a depth of 0–15 cm, processed and analyzed for pH, EC, soil organic carbon (SOC), available nitrogen (AN), available phosphorus (AP), available potassium (AK), available sulphur (AS), available iron (Fe), available manganese (Mn), available zinc (Zn) and available copper (Cu). Soil properties coefficients of variation (CVs) of soil properties widely varied from low (5.22%) to moderate (49.28%). The geostatistics and geographic information system (GIS) techniques were applied. Ordinary kriging and semivariogram analysis showed differed spatial variability patterns for the studied soil properties with spatial dependence ranged from moderate to strong. The semivariograms for the soil properties were best fitted with spherical model. The range of influence for available N, P, K and S were 268, 287, 497 and 706 m, respectively. The spatial ranges of available Fe, Mn, Zn and Cu were 1050, 1150, 1470, and 1430 m, respectively. The spatial dependence class was strong for EC, SOC, available P, K and was moderate for available N, S, Fe, Mn, Zn and Cu. The available N and P is categorized as low (<280 kg ha-1) and low (<11 kg ha-1) to medium (<22 kg ha-1), respectively were the main limiting factors in crop production. The availability K was categorized as medium (118-280 kg ha-1) to high (> 280 kg ha -1). The soil nutrient maps generated would help to provide precise fertilizer recommendations for sustainable production and environmental conservation
Effect of timing and graded levels of nitrogen and potassium in SRI cultivation
No full textA field experiment was carried out at Annamalai University Experimental farm, Annamalai nagar, during Kuruvai and Navarai in the year 2008-09. To study the timing and graded levels of nitrogen and potassium in rice crop under SRI (System of rice intensification) cultivation. The experiment was laid out on deep clay soil by adopting randomized block design with factorial technique (FRBD). The results of field experiment revealed that the maximum growth and yield attributes were recorded in the treatment which received P2O5 as fully basal dose and nitrogen as three split doses viz., 50% basal and 25% each at tillering and panicle initiation stages. Potassium was applied as 33.3% K2O each at 15, 30 and 45 DAT. This treatment significantly recorded higher grain yield of 6278.7 kg ha-1 in field experiment – I and 6577.9 kg ha-1 in field experiment – II; and the straw yield of 7010.3 and 7309.7 kg ha-1 in field experiment I and II respectively. The shoot and grain uptake of nutrients (N, P and K) were high during 15, 30 and 45 DAT and at harvest which received 33.3 % K2O each at 15, 30 and 45 DAT
Evaluating the processed beans of different cocoa (Theobroma cacao L.) accessions for quality parameters
No full textThe objective of this study was to evaluate the variability in quality parameters of different identified cocoa plus trees from Coimbatore district in Tamil Nadu. Thirty five (35) plus trees in two different farmers field were evaluated for their quality traits. The quality parameters like fat content (%), carbohydrate content (mg/g), protein content (mg/g), theobromine content (mg/g), caffeine content (mg/g), catechin content (mg/g) and caffeic acid content (mg/g). A rapid method like high performance liquid chromatography (HPLC) method is used for the determination of theobromine, caffeine, catechin and caffeic acid in cocoa beans. Among the 35 plus trees evaluated for bean quality, highest fat content was recorded in Tc (Vedapatti) 94, while highest carbohydrate content was recorded in Tc (Vedapatti) 64 and highest protein content was recorded in Tc (Vedapatti) 76. The highest theobromine was recorded in Tc (Vedapatti) 63, caffeine was recorded in Tc (Vedapatti) 91, while the amount of caffeic acid and catechin was the highest in Tc (Vedapatti) 76. This evaluation study showed wide variation for quality parameters. These variability may be used in further breeding program enhance the quality traits and improve flavours of the final product
TESTING AS A SERVICE (TAAS) – AN ENHANCED SECURITY FRAMEWORK FOR TAAS IN CLOUD ENVIRONMENT
No full textTesting becomes an important process not only in terms of exposure but also in terms of performance, safety, usability. Test Environment that directly represents the production environment is too expensive in terms of hardware, software licenses and more people. Cloud computing supports an everything as a service (XaaS) Delivery model. Testing-as-a-service (TaaS) is a new model to provide testing capabilities to end users. Users save the cost of complicated maintenance and upgrade effort, and service providers can upgrade their services without impact on the end-users. Due to uneven volumes of concurrent request, it is important to address lack of security policy and evaluating the right tool for application of TaaS platform in a cloud environment
