Sewage irrigated vegetable production systems around Hubli-Dharwad
No full textABSTRACT Hubli-Dharwad twin city is the second largest urban area in Karnataka State, with a population of 800,000. Around 60 million litres of waste water are produced per day, none is treated. The waste water flows into natural courses, and along their routes farmers exploit this resource for irrigation of vegetables. The climate of Hubli-Dharwad is semi-arid (800 mm p.a.), so dry season cultivation of vegetables is a profitable enterprise. Apart from sewage water irrigation, dry season vegetable cultivation in this area is restricted to farms with borewells. However, these are expensive to install and the water table is subject to fluctuations in depth. The content of heavy metals in waste water in Hubli-Dharwad is minimal, due to the absence of heavy industry. Total suspended solids (110 mg/1) and solutes (780 mg/1) are high. Total N is 12.1 mg/1. The site studied consists of 40 ha irrigated by sewage. This is usually raised from the water course by electric pump to the head of the field, from where it is distributed through channels by gravity. Vegetable plots on individual holdings tend to be small, typically 0.6 to 0.8 ha, but intensive, with four or five crops being raised each year. In order of preference, main vegetables cultivated are Cauliflower (Brassica oleraceae var. botrytis), cucumber (Cucumis sativus), beetroot (Beta vulgaris), spinach beet (B. vulgaris var. bengalensis) and amaranthus (Amaranthus tricolor). Advantages for the farmer are increases of 25 to 50% in yield compared to crops grown with borewell irrigation, lower fertilizer inputs, protection from erratic rainfall conditions, and being able to take advantage of the three to five fold increases in vegetable market prices in the off-season. Disadvantages are increased prevalence of conjunctivitis and dermatological conditions, and greatly increased incidence of weeds and pests. The most problematic weeds are Portulaca oleraceae and Cyperus rotundus, which are removed by cultivation and hand pulling. The most serious pests are diamond back moth on brassicas and fruit borer (Helicoverpa armigera) on numerous crops. The pests exhibit resistance to a wide range of insecticides, and in serious years may render entire crops unsuitable for sale. Spraying with systemic organo-phosphates every week is often practiced, the farmer wearing no protective clothing. It is unlikely that this method of cultivation can be eradicated until full sewage treatment is installed. The challenge is how to minimise the most deleterious effects of this cropping system. For the consumer these include potential contamination by coliform bacteria and high pesticide residues. In addition the farmer faces high risk of pesticide poisoning. Potential ways forward are discussed

Homemakers’ Attitude towards Solid Waste Management in Urban Area of Hubli-Dharwad
No full textProper waste management is a major concern of public health. It is necessary to create positive behavioral changes toward waste management among the public to control diseases. Objectives were to determine the attitude toward solid waste management among the households of Hubli - Dharwad city in Karnataka, India. A community based cross sectional study was conducted in 67 wards of Hubli- Dharwad city located in the Dharwad district of Karnataka state from January 2021 to December 2021. A total of 400 households were studied and multistage sampling was done. Data was collected by direct interview using a pre-questionnaire and analyzed using SPSS software. The participants responsible for waste management in the household were women. Out of the 400 participants, 83%, 11% and 6% were Hindus, Muslims and Christians respectively. The majority of them (82%) had an educational qualification of high school and were housewives. About 47% of the study population belongs to the upper middle class. Their major sources of information about solid waste management were Self Help Groups (SHGs). In the study, 93.8% of the studied population had above average attitudes and 6.2% had below average attitudes toward household waste management. Almost 70% had the belief that the government is not doing anything to fix the garbage problem. About 97%, 88.6% and 92% were willing to do composting, segregation and recycling of waste respectively. . Continuous awareness programs have to be conducted on safe waste disposal and efforts should be made to sustain the supervision of household waste management.</jats:p

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The age and mode of presentation of benign prostatic hyperplasia at Hubli in Karnataka
No full textBackground: The peculiarities of the prostate are that in old age when most of organ regresses in size it enlarges and causes trouble. By virtue of its position, it guards outlet of urinary bladder. It must be admitted that even today the extent nature of etiology, pathogenesis and diagnosis are all-debatable. Therefore, the present study was aimed at elucidating the age and mode of Benign Prostatic Hyperplasia among the patients in and around Hubli, Karnataka.Methods: The study was conducted after the institutional ethical committee approval and written informed consent from all the patients. 21 cases of BPH were included in the present study. The signs and symptoms of mode of presentation were recorded. The urine was examined for the presence of albumin, pus cells, epithelial cells and RBCs. Results: The maximum incidence of the disease was in the age group of 60-69 years. Majority of the patients had difficulty in micturition followed by increased frequency of micturition both during day and night Patient with retention usually had distension of bladder. These patients complained of dull aching pain in the suprapubic area and in the groin region. Burning micturition (14.28%), dribbling of urine (4.76%), urgency (4.76%), and haematuria (4.76%) were present. Routine urine examination showed albumin (28.56%), pus cells (23.80%), epithelial cells (19.04%) and haematuria (4.76%). Conclusion: Incidence of BPH at Hubli region of Karnataka is 0.3001% of total hospital admission. The maximum age incidence of BPH is in the age group of 60-69 years. Majority of the patients had difficulty in micturition increased frequency of micturition both during day and night a large number of cases show association with presence of urinary tract infection.
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
