DETERMINATION OF DIAGNOSTIC SIGNIFICANCE OF WRIST CIRCUMETRIC SIGN IN SIDDHA SYSTEM OF MEDICINE

Aim: Determination of diagnostic significance of wrist circumetric sign in siddha system of medicine.Materials and methods: Patients are randomly selected between the age 13years to 70 years with selected diagnoses like Madhumegam, Athikuruthiazhutham (Hypertension), Thamaraganoi, Putrunoi, Kalanjagapadai (Psoriasis), Moolam, Powthiram (Perianal fistula), Vali azhal keel vayu, Pakkavatham, Karupaisathaikatti (Uterine fibroids).Results and observation: Most of the patients MKN values fell within the range of 9-9¾ fb. This range of 9-9¾ fb MKN, was observed in Athikuruthiazhutham, Putrunoi, Moolam, Powthiram, Thamaraganoi, Madhumegam, Pakkavatham, healthy volunteers. 8-8¾fb MKN range was observed in 41.5% of Kalanjagapadai and vali azhal keel vayu cases. 10 - 10¾fb was observed in 43.1 % of patients with Karuppaisathaikattigal (Uterine fibroids).Conclusion: Since all other diseases had non-specific Manikkadai nool range except the condition Karupaisathaikattigal (uterine fibroid), Manikkadai nool can be used to assess screening test in detecting the presence of uterine fibroids and cardiac diseases according to this study.

Estimation of soil carbon pools under major cropping systems of Mayiladuthurai district of Cauvery Delta Zone, Tamil Nadu, India

Soil organic carbon (SOC) is a potential indicator of soil quality and ecosystem sustainability. The present study aimed to evaluate SOC pools under major cropping systems of Mayiladuthurai district of Tamil Nadu. The composite samples were collected from two depths (0-15 and 15-30 cm) by stratified random sampling and were analysed for pH, EC (Electrical conductivity), C fractions, inorganic carbon and permanganate oxidisable carbon by standard procedures. The SOC content under different land use was in the order of Forestry > Rice – pulses > Rice – cotton > Sugarcane > Uncultivated. The mean SOC content of the study area was 12.58 Mg ha-1, where the majority of the area falls under low to medium rating of SOC. Hence, cultivation practices should incorporate activities that increase SOC to maintain soil quality. SOC was positively correlated with fractions of carbon – CVL (r = 0.37**), CL (r = 0.65**) and CLL (r = 0.58**), indicating changes in land use would affect the carbon dynamics of the ecosystem. The root biomass, aeration status, microbial activity, nutrient reserves and inherent soil characteristics influenced SOC to decrease with depth. The PCA analysis revealed that the variation in carbon dynamics of the study area was influenced by SOC, CLC, CLL and non-labile carbon due to differences in land management practices. Therefore, such soil management practices will be a powerful tool to sequester carbon, which supplements climate change mitigation

Measuring Wind Turbine Parameters Using Microcontroller as Data Acquisition

ABSTRACT: The energy extracted from wind with the help of wind turbines is used to produce electricity. Hundreds of wind turbines combine together to form wind farms. They are connected to electrical power transmission network. Wind power can be used as an alternative to fossil fuels as it is widely available. wind turbines are used for converting wind energy into useful form of energy. In this paper the various parameters of wind are measured and monitored by setting up a system. The parameters are pressure, current ,voltage and direction. The interface to pc is done using a microcontroller which is used as a data acquisition system and proteus design suite is used for simulation. The idea of using microcontroller as a data acquisition will be economic and more convenient for the user

Field Validation on Incorporation of Rice Husk Biochar and Paddy Straw Compost on Crop Attributes and Soil Properties in Rice Ecosystem

Aim: To study the effect of rice husk biochar and rice straw compost on Rabi season rice cultivation. Study Design: The randomized block design was used. The treatments of different doses of soil amendments like rice husk biochar, rice straw compost and recommended fertilizer doses are applied. Place and Duration of Study: The experimental trial was conducted during the Rabi season (January - April) of 2022 at Tamil Nadu Rice Research Institute, Aduthurai, Tamil Nadu, India. Methodology: The study consisted of 11 sets of RBD design treatments replicated thrice. The rice variety of ADT57 Short duration variety was used for this study. The observation has been recorded during the crop growing period at regular intervals. Results: The study results revealed that application of PSB @ 2kg/ha + RSC @ 5 t/ha + 75% RDF (T10) treatment showed the highest plant growth parameters like plant height (27.88, 74.22 and 108.89 cm), number of tillers m-2 (122, 620 and 642), leaf area index (2.62, 6.53 and 8.47), SPAD reading (47.22, 43.64 and 40.46), root length (18.86, 37.45 and 56.31 cm) and root volume (17.85, 26.01 and 37.77 ml) at 30, 60 and 90 DAT respectively and yield parameters like grain yield (5133 kg/ha), straw yield (7090 kg/ha), panicle length (25.28cm) and number of productive tillers m-2 (571.6) and was significantly on par with application of PSB @ 2kg/ha + Rice Husk Biochar (RHB) @ 5 t/ha + 75% RDF (T6) and superior over the other all treatments. Plant growth parameters of application of PSB @ 2kg/ha + Rice Husk Biochar (RHB) @ 5 t/ha + 75% RDF (T6) recorded the plant height (27.41, 73.76 and 108.29 cm), number of tillers m-2 (118, 613 and 630), leaf area index (2.54, 6.42 and 8.38), SPAD reading (46.26, 43.10 and 40.20), root length (18.35, 37.05 and 55.40 cm) and root volume (17.42, 25.44 and 37.33 ml) at 30, 60 and 90 DAT respectively and yield parameters like grain yield (4953 kg/ha), straw yield (7077 kg/ha), panicle length (25.07 cm) and number of productive tillers m-2 (555). So, the application of PSB @ 2 kg/ha + RSC @ 5 t/ha + 75% RDF has recorded the best results than all other treatments. With respect to soil properties, application of Rice husk Biochar (RHB) @ 5t/ha + 75% RDF (T4) has reduced the soil bulk density (from 1.52 to 1.47) and application of rice straw compost @ 5t/ha has increased the soil pH (from 6.58 to 7.14) as compared to other treatments whereas the nutrient status (nitrogen (from 212 to 266 kg ha-1); phosphorus (from 45.41 to 61.59 kg ha-1) and potassium (from 192 to 218.4 kg ha-1) has increased by application of PSB @ 2kg/ha + RSC @ 5t/ha + 100% RDF (T11) than other treatments
