FAILURE MODES AND EFFECTS ANALYSIS OF DRIVING MECHANISM IN HORIZONTAL PLANNING MACHINE

In this paper the failure analysis and optimization of horizontal mechanism in a horizontal planning machine rack and pinion arrangement is needed for the translation movement. The relative motion between the fixed and movable bed are being in friction with the ability of V guide ways. And the drive of this mechanism is rack and pinion arrangement. In general, wear occurring in V-Guides ways and drive mechanism are not equal. So that, the variation of the wear amount should affect the surface level of to be machined component. The failure is rectified to implement the new mechanism (arrangement) in driven portion of the horizontal mechanism. The main concept of this paper is that the surface level of the machined component has to be fine. The modification of the mechanism is to change the position of gear rack and pinion. In existing, the gear tooth is in horizontal and crosswise to the guide ways. Instead of that, the gear tooth is perpendicular to the guide ways. If the wear occurred in this modified one, the gear engaging length will increase. The modified mechanism does not affect the addendum and dedundum of the gear profile

Clonal variability in black pepper hybrid Panniyur 1

Forty two clones of twenty year old Panniyur 1 plants, grown as a monocrop of black pepper, were analyzed for variations in yield contributing factors as well as quality paralTIeters over a period of three years. The analysis of the data has revealed that the plants exhibited considerable amount of variability for characters under study and the standard deviation was lnore for berries spike-1 and yield. Among the quality characteristics, oleoresin exhibited more variability than piperine. From the non hierarchical Euclidean cluster analysis it is observed that the plants can be clustered ideally in to five clusters based on their mean performance. The intra and inter cluster distance was more for cluster number 4, which later culminated in Inaximuln nUlnber of plants (13) having high yield and oleoresin. &nbsp

Stability analysis of ginger (Zingiber officinale Rose.) genotypes

Ten genotypes of ginger (Zingiber officinale) were subjected to stability analysis based on their evaluation for 6 years at Regional Agricultural Research Station, Ambalavayal (Kerala, India). All the genotypes differed significantly for tiller number, leaf number and yield. Stability analysis revealed the superiority. of Ernadan and Kuruppampady as they expressed high mean yield, non significant S2di values and a regression nearing unity. &nbsp

A comparative single dose study of oral acetaminophen 650 mg to its standard 500 mg dose in adult pyrexia patients in a tertiary care hospital

Background: Acetaminophen commonly called as paracetamol is the most used ‘over-the-counter’ analgesic for headache, musculoskeletal pain, dysmenorrhoea etc. It is the best drug to be used as antipyretic for fever due to any cause and safest to be prescribed in all age groups. Antipyretic dose of acetaminophen is 325 to 650 mg; 3 to 4 times a day and is available in the strength of 650 mg and 500 mg tablets. This study was conducted to analyse the antipyretic efficacy and safety profile of two different doses of acetaminophen in patients with low grade fever.Methods: 300 hospitalised patients aged more than 18 years, in department of General Medicine, having low grade fever (38º to 39º C) were randomly allocated into two groups of 150 each, group A received 500 mg and group B received 650 mg of single oral dose of acetaminophen tablets. Oral temperature was measured before dosing, 30 minutes after dosing, one hour, two hourlies thereafter for 6 hours after the dose. Safety was assessed by monitoring for adverse effects during the study and 24 hours after administration of the assigned drug.Results: There was a statistically significant decrease in temperature in group B patients from baseline 39.06±0.87º C to 37.02±0.89º C at the end of 6th hour as compared with 39.18±0.80º C to 38.03±0.77º C in Group A patients (p=0.031).Conclusions: Our study concluded that acetaminophen in a dose of 650 mg is highly efficacious antipyretic drug compared to acetaminophen 500 mg with no adverse effects

Root colonization by Piriformospora indica promotes growth, induces earliness in flowering, enhances yield and citrulline content in watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai)

Piriformospora indica is a unique and versatile fungal root endophyte that colonizes a wide range of plant species, and promotes growth, early flowering and yield in addition to enhanced tolerance to abiotic and biotic stresses. The performance of P. indica colonization in water melon was evaluated in two improved, seeded watermelon varieties viz., Sugarbaby, and Durgapur Lal and two seedless F1 hybrids viz., Swarna and Shonima. The seedlings of the varieties colonized with P. indica increased root and shoot growth biomass compared to the control. Early initiation of female flowers was also observed due to the fungal colonization. Indole acetic acid (IAA) and Gibberellic acid (GA) contents of watermelon seedlings were enhanced in P. indica-colonized plants compared to non inoculated control plants. The endophytic association in watermelon also increased the fruit yield in terms of the number and size of fruits, the number of seeds per fruit in seeded varieties, and citrulline, lycopene, and beta-carotene contents. Interestingly, the severity of bud necrosis was significantly reduced in P. indica-colonized plants compared to the uninoculated control. This is the first report on P. indica root colonization in watermelon which positively influences growth, yield and quality of seedless F1 hybrids and seeded varieties of watermelon. This study also indicated the potential of P. indica to overcome the limitations of seedless watermelons in growth and yield compared to the seeded varieties. Therefore, there is tremendous scope for improving watermelon through P. indica-colonization including the seedless F1 hybrids

Optimum dose of nitrogen and potassium for ginger in Wynad, Kerala

Study on nutrient requirement of ginger in Wynad, Kerala showed the positive effect of higher, doses of Nand K on the yield. Among the 16 levels of Nand K, 3 combinations viz., 150 kg N, 50 kg K; 150 kg N, 100 kg K and 75 kg N, 150 kg K ha-1 were found to be significantly superior with respect to yield. Among the vegetative characters, plant height was found to be significantly influenced by nitrogen. The optimum dose of Nand K derived from the quadratic equation was 144 kg and 109 kg ha-1 respectively. &nbsp
