Investigating suitability of treated wastewater for agriculture in Hawassa, Sidama region, Ethiopia

This study is based on the quality of wastewater from Hawassa University surroundings, which was assessed to determine its suitability for irrigation purposes during 2019. Grab samples of influent and the treated water were taken for assessing for quality parameters. The study revealed that the treated water could be used for irrigation purpose with some moderate restrictions. Even though Electrical Conductivity (EC) and Total Dissolved Solids (TDS) permit to irrigate fruit trees and fodder crops, there is a risk of soil degradation due to high value of Sodium Adsorption Ratio (SAR). Results also indicated that carbonate, potassium and phosphate exceeded the specified limits for wastewater reuse in agriculture. Despite increased nutritive elements, continuous use of treated sewage water for irrigation will make the soil acidic. Analysis of soil parameters indicated that there is an increase in nitrogen, phosphate and potassium nutrient levels considerably to benefit crop production but increase in soil EC is a serious concern.

Phytochemistry and Ethanopharmacological Studies on Rubia cordifolia Linn. (Rubiaceae)

Ethanolic extracts of the leaves of Rubia cordifolia L. (Rubiaceae) (ERC) were investigated for their phytocompounds, in vitro and in vivo immunopharmacological properties. Immunomodulatory effects of this plant extract were proved in Cyclophosphamide (CP) -induced immunosuppressed animal models. Albino rats were treated with the aqueous extract of ERC and Cyclophosphamide. The Total count (TC) and Differential count (DC) of microphages and blood clotting assay were affected due to the suppressive effect of Cyclophosphamide. Administration of plant extract to CP- exposed animals resulted in enhanced immune responses

Background: The aim of this prospective study is to analyse the factors influencing development of trans urethral resection of prostate (TURP) syndrome in benign Prostatic hyperplasia patients with various co morbid medical illness in Thanjavur Medical College Hospital, from February 2015 to January 2017.Methods: This prospective study was done among 38 benign hyperplasia prostate patients with various co morbid medical illness underwent TURP. Pre-operative and post-operative serum sodium levels correlated with signs and symptoms developed in various prostate gland sizes, resection times and volume of irrigation fluids.Results: Sodium level has gone down to 14 meq/L, gone up to 2 meq/L post-operatively. Major fluctuations in serum sodium was seen in prostate size more than 50 grams, resection time more than 40 mints, irrigant volume more than 24 litres. Mean sodium decrease was increased when gland size was increased, resection time was increased, irrigant volume was increased.Conclusions: In renal insufficiency patients, it is safe to complete the procedure within 40 minutes and restrict irrigant volume 15 litres, in coronary artery disease patients it is safe to restrict irrigant fluid volume less than 20 litres. In Diabetes Mellitus patients, it is safe to restrict irrigant fluid volume less than 24 litres. In hypertensive patients, it is safe to restrict the resection time less than 45 minutes. In patients with Diabetes and hypertension, it is safe to restrict the resection time less than 40 minutes and irrigant fluid less than 20 litres

Prevalence of aspirin resistance in coronary artery disease among Indian patients

Background: Aspirin is one of the most widely consumed drugs in this world. The first report of a possible antithrombotic effect of aspirin appeared in 1953 in the Mississippi Valley Medical Journal. Objective of the study was to determine the prevalence of aspirin resistance among Indian patients with coronary artery disease.Methods: Patients were prospectively enrolled from all stable cardiac patients presenting to the outpatient wing of Department of Medicine of a tertiary care centre in South Kerala. Duration of study was one year. All patients who were more than 21years old and who had taken 150mg of aspirin for the previous seven days were eligible for enrolment.Results: Aspirin resistance was found in 9.3% of patients. 17.3% of patients were aspirin semi responder.Conclusions: There was statistically significant correlation of aspirin resistance with presence of diabetes mellitus, systemic hypertension and dyslipidemia. Cigarette smoking did not show any significant association with aspirin resistanc

Real-Time Simulation of Efficient Energy Management Algorithms for Electric Vehicle Chargers

Transportation electrification is happening at a rapid pace around the globe in response to the climate change mitigation measures taken by the regulatory agencies to curb tailpipe emissions. As the electric vehicle technology evolved, the size of on-board storage units has increased, which require charging from an external energy source. Renewable charging of electric vehicles is an attractive option to reduce the carbon footprint of an electric vehicle. The intermittent nature of the renewables necessitates a storage unit to provide continuous power. With a battery complementing solar generation, a power converter is deployed to interface these sources and storage units with the electric vehicle for charging. The converter shall now have to operate to quench the charging requirements by sourcing power from solar generation and storage elements. The converter also has to capture the generated solar power during the non-charging period and store it in the battery. All these functional requirements demand a robust energy management strategy to utilize all available sources and storage units efficiently without compromising load requirements. A Stateflow-based energy management algorithm for a three-port converter is proposed in this work. The proposed algorithm is implemented using OPAL-RT, and the real-time simulation results are presented

Expressing emotions in words: Facebook text-based comments in Tamil

Language being used as a communication tool is embedded with emotions. Emotions in language are obvious in face-to-face (F2F) communication than in any other forms of communications. Media Richness Theory explains that the richer the media is the more successful communication will be and vice versa (Moczynski, 2010). This means text-based communication such as letters, e-mails, memo and so forth lacking of non-verbal cues like intonations, facial expressions, body movements and others, will not be as successful as F2F communication. On the other hand, there are also studies which have proven that computer mediated communication can convey non-verbal cues as effective as in F2F communication by manipulating the fonts with capitalization or using coloured fonts to express emotions (Mali, 2007; Boonthanom, 2004). Nevertheless, how is it possible to communicate non-verbal informations in a language like Tamil which does not have capital letters or colour code? The aim of this study is to identify the techniques used by Tamils in conveying emotions through words in facebook. This paper further discusses the frequent and helpful techniques used in Tamil communication. Samples chosen for this study were forty active facebook users who have good language competency in Tamil

An on-line sample pretreatment technique for the HPLC analysis of plant samples.

A continuous-flow, on-line sample pretreatment technique using a silica gel microsyringe extractor has been developed. All steps including extraction, separation, clean-up, and concentration occur in the microsyringe. The overall sample pretreatment process takes 0.99. Complex plant samples of Sambucus Mandshurica Kitag have been tested using this method. Fluorene, phenanthrene, pyrene, and plant hormones were detected in all the samples, and concentrations ranged from 24.2–34.9, 43.8–67.1, 25.9–29.2, and 14.5∼110.8 ng/g, respectively

Assessment of genetic and functional diversity of phosphate solubilizing fluorescent pseudomonads isolated from rhizospheric soil

<p>Abstract</p> <p>Background</p> <p>Phosphorus is an essential macronutrient for the growth of plants. However, in most soils a large portion of phosphorus becomes insoluble and therefore, unavailable to plants. Knowledge on biodiversity of phosphate-solubilizing fluorescent pseudomonads is essential to understand their ecological role and their utilization in sustainable agriculture.</p> <p>Results</p> <p>Of 443 fluorescent pseudomonad strains tested, 80 strains (18%) showed positive for the solubilization of tri-calcium phosphate (Ca₃(PO₄)₂) by the formation of visible dissolution halos on Pikovskaya's agar. These phosphate solubilizing strains showed high variability in utilizing various carbon sources. Numerical taxonomy of the phosphate solubilizing strains based on their carbon source utilization profiles resulted into three major phenons at a 0.76 similarity coefficient level. Genotypic analyses of strains by BOX (bacterial repetitive BOX element)-polymerase chain reaction (PCR) resulted into three distinct genomic clusters and 26 distinct BOX profiles at a 80% similarity level. On the basis of phenotypic characterization and <it>16S rRNA </it>gene phylogenetic analyses strains were identified as <it>Pseudomonas aeruginosa, P. mosselii, P. monteilii, P. plecoglossicida, P. putida, P. fulva </it>and <it>P. fluorescens</it>. These phosphate solubilizing strains also showed the production of plant growth promoting enzymes, hormones and exhibited antagonism against phytopathogenic fungi that attack on various crops. Gene specific primers have identified the putative antibiotic producing strains. These putative strains were grown in fermentation media and production of antibiotics was confirmed by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC).</p> <p>Conclusion</p> <p>Present study revealed a high degree of functional and genetic diversity among the phosphate solubilizing fluorescent pseudomonad bacteria. Due to their innate potential of producing an array of plant growth promoting enzymes, hormones and antifungal metabolites these phosphate solubilizing strains are considered to play a vital role in plant growth promotion, disease suppression and subsequent enhancement of yield.</p
