MEDICINAL PLANTS OF SELECTED WETLANDS IN PANNISSERY AREA, THRISSUR DISTRICT, KERALA–A PRELIMINARY SURVEY

Objective: Wetlands are vital ecosystem which provides livelihoods for millions of people who live within around them. Man depends on wetlands for most of his needs from time immemorial. The present study is a preliminary step for the identification of valuable medicinal plants in the wetlands of Pannissery area. This attempt was made since it is equally important to understand the traditional medicines and beliefs as well as to have scientific awareness for protection and conservation of the sewetlands. Methods: Frequent field visits were carried out from September 2018 to January 2019 to collect different Wetland medicinal plants in Pannissery area, Kandanassery Panchayath, Thrissur district. Plants were collected carefully with hand and identified by using the standard literature such as Flora of the Presidency of Madras by J. S. Gamble, 1915-1936. The collected plants were authenticated by a plant Taxonomist Dr. Udayan. P. S. from the Post Graduate and Research Department of Botany, Sree Krishna College, Guruvayur. Results: A slight alteration of the wetland may result in the disappearance or the extinction of these plants [1]. Conclusion: This will ultimately result in large scale economic loss in terms of the medicinal product. Apart from the loss of plants, this will also result in the loss of local knowledge on the medicinal properties of these plants which very often can't be retrieved. An attempt has been made to document some of the little known medicinal properties of wetland plants used by local community

MEDICINAL PLANTS OF SELECTED WETLANDS IN ARIYANNUR, THRISSUR DISTRICT, KERALA–A PRELIMINARY STUDY

Objective: Wetlands are a vital ecosystem which provides livelihoods for millions of people who live within around them. The main aim of this study is to identify the wetland medicinal plants, medicinal values of wetland medicinal plants, to evaluate the current status of the medicinal plant diversity in wetlands of Ariyannoor area, importance of wetlands, to build awareness. Methods: Frequent field visits were carried out from September 2018 to January 2019 to collect different Wetland medicinal plants in Ariyannur area, Kandanassery Panchayath, Thrissur district. Plants were collected carefully with hand and identified by using the standard literature such as Flora of the Presidency of Madras by J. S. Gamble, 1915-1936. The collected plants were authenticated by a plant Taxonomist Dr. Udayan. P. S. A total of 10 plant species was collected and identified during the investigation with potential medicinal value. Results: These plants are used for curing more than 20 diseases, including Blood dysentery, cough and cold, skin diseases, anemia etc. Herbs have been called part of “nature’s pharmacy”. Although their action can in some ways be similar to modern drugs, herbal remedies are generally gentler and safer. Many of the drugs used in conventional medicine are derived from herbs [1]. Conclusion: Slight alteration of the wetland may result in the disappearance or the extinction of these plants2. This will ultimately result in large scale economic loss in terms of the medicinal product. Apart from the loss of plants, this will also result in the loss of local knowledge on the medicinal properties of these plants which very often can't be retrieved. An attempt has been made to document some of the little known medicinal properties of wetland plants used by local community

Bulk viscous matter and recent acceleration of the Universe

We consider a cosmological model dominated by bulk viscous matter with total bulk viscosity coefficient proportional to the velocity and acceleration of the expansion of the universe in such a way that $\zeta=\zeta_{0}+\zeta_{1}\frac{\dot{a}}{a}+\zeta_{2}\frac{\ddot{a}}{\dot{a}}.$ We show that there exist two limiting conditions in the bulk viscous coefficients, ($\zeta_{0}$, $\zeta_{1}$, $\zeta_{2}$) which corresponds to a universe having a Big-Bang at the origin, followed by an early decelerated epoch and then making a smooth transition into an accelerating epoch. We have constrained the model using the type Ia Supernovae data, evaluated the best estimated values of all the bulk viscous parameters and the Hubble parameter corresponding to the two limiting conditions. We found that even though the evolution of the cosmological parameters are in general different for the two limiting cases, they show identical behavior for the best estimated values of the parameters from both the limiting conditions. A recent acceleration would occur if $\tilde{\zeta}_{0}+\tilde{\zeta}_{1}>1$ for the first limiting conditions and if $\tilde{\zeta}_{0}+\tilde{\zeta}_{1}<1$ for the second limiting conditions. The age of the universe predicted by this model is found to be less than that predicted from the oldest galactic globular clusters. The total bulk viscosity seems to be negative in the past and becomes positive when $z\leq0.8$. So the model violates the local second law of thermodynamics. However, the model satisfies the generalized second law of thermodynamics at the apparent horizon throughout the evolution of the universe. We also made a statefinder analysis of the model and found that it is distinguishably different from the standard $\Lambda$CDM model at present, but shows a de Sitter type behavior in the far future of the evolution.Comment: 14 figure

Morphological characterization of Ampelomyces spp., a hyperparasite of Bhendi (Abelmoschus esculentus (L.) Moench) powdery mildew

Ampelomyces is a naturally occurring hyperparasite on powdery mildews. Survey was conducted in major bhendi (Abelmoschus esculentus (L.) Moench) growing districts of Tamil Nadu during June 2014 to assess the incidence of powdery mildew and to collect different isolates of Ampelomyces spp. The results of the survey revealed that the disease incidence ranged from 15.54 to 63.45 %. Ten isolates of Ampelomyces spp. were collect-ed from surveyed areas of powdery mildew. Isolation of Ampelomyces spp. was done from powdery mildew infected bhendi leaf parasitized by Ampelomyces spp. using tissue segment method. All the isolates were identified by their morphological characters. The colour of the colonies in various medium was brownish black to greenish white. Most of the isolates showed radial and fluffy growth pattern with raised growth. The pycnidia of different isolates of Ampelomyces varied in their shape and were mostly ovoid, ellipsoid, cylindrical, pyriform to globose in shape. The size of pycnidia varied from 29.2-72.5×22.4-43.1 ?m. The number of pycnidia was found to be more in isolates viz., TNAU-AQ101 and TNAU-AQ103. Pycnidiospores are hyaline, unicellular and guttulate in shape. The pycnidial production was higher in TNAU-AQ101 and TNAU-AQ103. Application of agrochemicals is one of the oldest and most effective methods to manage powdery mildew disease. However, incessant use of these agrochemicals has many demerits such as development of resistance to pathogens, residual toxicity and environmental pollution. Hence, search for an alternative means for disease management is envisaged. The genus Ampelomyces are the major antagonists as an alternative of Erysiphales fungi being a significant group of phytopathogens

MARKET SAMPLE SURVEY OF CROCUS SATIVUS LINN. TO ASSESS THE GENUINITY FOR USING ANTIOXIDANT ACTIVITY, TOTAL PHENOLIC CONTENT AND HIGH-PRESSURE THIN LAYER CHROMATOGRAPHY USING DETECTION OF FLAVONOIDS

Objective: Herbalism is a traditional medicine or folk medicine practice based on the use of plants and plant extracts. Many of the drugs used in conventional medicine are dried from herbs. Despite the fluctuation in prices in international markets, saffron was still remained the most expensive spice. The main aim of this study is to examine the antioxidant activity, total phenolic content, high-pressure thin layer chromatography using flavanoid analysis and adulteration detection of saffron. Crocus sativus. Linn is a perennial stemless herb of the Iridaceae family. Saffron stigmas of sample1, sample2, sample3and sample4 are collected from different rates of the market sample from Thrissur district, sample5 collected from the Oushadhi premises, and it is collected from Himachal Pradesh. Methods: In this study detecting the antioxidant activity, total phenolic content, high-pressure thin layer chromatography using flavanoid analysis of different samples of saffron stigmas. The extracts were prepared by using ethanol as a solvent. Results: Safranal is present only in s5 sample. It is the main essential volatile oil responsible for the saffron characteristic such as odour. Phenolic content is varied in different market samples. The amount of phenolic compounds in the saffron extract was determined using the Folin-ciocalteau reagent. Total phenolic content is the help to detect the pure and fake saffron. The phenolic content is higher in S5. Sample S5 showed 0.737 mg/ml phenolic content. Lowest level of phenolic content in sample S3. Sample S3 showed 0.0887 mg/ml phenolic content. Sample S4 showed 0.564 mg/ml total phenolic content. Sample S1 showed 0.416 mg/ml total phenolic content and sample S2 showed 0.267 mg/ml phenolic content. Antioxidant activity is higher in sample s5. and it is different in different market samples. Sample 5 stigma posses higher antioxidant activity. Sample S5 showing 14.88% antioxidant activity in 100 mg/ml concentration, 7.26% in 80 mg/ml concentration, 2.23% in 60 mg/ml concentration, 2.21% in 40 mg/ml and 1.01% in 20 mg/ml concentration. Sample S3 showed the lower antioxidant activity in 0.1% in 60 mg/ml concentration and 0.1% in 80 mg/ml. Ascorbic acid standard showing 14.89% in 100 mg/ml concentration, 7.26% in 80 mg/ml concentration, 4.56% in 60 mg/ml concentration, and 3.1% in 40 mg/ml concentration, and 1% in 20 mg/ml concentration. Flavonoid content is different in different samples. It is present highly present in sample s1 and s5. sample s3 do not contain the Flavanoid. The quality of the samples depend on the price values. Conclusion: The authenticity of saffron is an extremely important matter for the industry and for the consumers in view of security and protection,quality assurance, active properties and last but not least, economic impact. Despite the fluctuation in prices in international markets, saffron was and still remains the most expensive spice. The genuine saffron samples possess higher price value. The fake saffron available in the market with lower price value. The quality of the saffron depends upon the price values. These observations would be of immense value in the botanical identification and standardization of the drug in crude form and would help to distinguish the drug from its other spices

Wireless Dual DC Motor Control

Abstract—“WIRELESS DUAL DC MOTOR CONTROL ” is less complex than the standard dc motor control. The device aim is how to build dual dc motor control system, combined with a wireless receiver and transmitter which will tell the two independent motors at which speed they should move and in what direction. There are four core components: input system for the transmitter, a wireless transmitter, wireless receiver and a motor controller connected to the receiver. Transmission and reception are enabled using XBee module. The information is sent to the motor through an XBee transmitter via system software ‘Terminal’. XBee receiver placed on the robot will automatically connect with the transmitter and begin receiving data. The receiver will receive the unique values from an XBee module and tells each motor independently which way to turn and how fast to move. Software is loaded into the PIC. Motor control combined with wireless transmitter and receiver is an uncomplicated and low cost design that works reliably

DEMING VALUES AND TEACHERSâ€: SURVEY RESULTS PRESENTED AS A RESEARCH PAPER

Quality is an imperative factor considered for surveys in almost all organizations. It is a common term used for characterizing a service, product or an individual trait. The study shows the applicability of Deming's 14 point principles of quality management among teachers. In this competitive world people give more importance to ensure quality in every sector. Education sector is also treated as a globally competing marketplace in the present scenario. It is therefore indispensable to meet global standards to survive with the competitors. William Edward Deming is the Father of Total Quality Management.  His 14-point principles are the major highlight of this study. The analysis revealed an optimistic result and it could be fixed that the topic has a scope for further learning.    Â
