A Semantic approach for effective document clustering using WordNet
Leena H. Patil,Mohammed Atique
Computer Science , 2013,
Abstract: Now a days, the text document is spontaneously increasing over the internet, e-mail and web pages and they are stored in the electronic database format. To arrange and browse the document it becomes difficult. To overcome such problem the document preprocessing, term selection, attribute reduction and maintaining the relationship between the important terms using background knowledge, WordNet, becomes an important parameters in data mining. In these paper the different stages are formed, firstly the document preprocessing is done by removing stop words, stemming is performed using porter stemmer algorithm, word net thesaurus is applied for maintaining relationship between the important terms, global unique words, and frequent word sets get generated, Secondly, data matrix is formed, and thirdly terms are extracted from the documents by using term selection approaches tf-idf, tf-df, and tf2 based on their minimum threshold value. Further each and every document terms gets preprocessed, where the frequency of each term within the document is counted for representation. The purpose of this approach is to reduce the attributes and find the effective term selection method using WordNet for better clustering accuracy.

Effect of chronic administration of green tea extract on chemically induced electrocardiographic and biochemical changes in rat heart
Patil Leena,Bothara Sunil,Balaraman R
International Journal of Green Pharmacy , 2010,
Abstract: Many chemicals induce cell-specific cytotoxicity. Chemicals like doxorubicin induce oxidative stress leading to cardiotoxicity causing abnormalities in ECG and increase in the biomarkers indicating toxicity. Green tea extract (GTE), Camellia sinensis (Theaceae), is reported to exert antioxidant activity mainly by means of its polyphenolic constituent, catechins. Our study was aimed to find out the effect of GTE (25, 50, 100 mg/kg/day p.o. for 30 days) on doxorubicin-induced (3 mg/kg/week, i.p. for 5 weeks) electrocardiographic and biochemical changes in rat heart. It is observed that GTE administered rats were less susceptible to doxorubicin-induced electrocardiographic changes and changes in biochemical markers like lactate dehydrogenase (LDH), creatine kinase (CK), and glutamic oxaloacetate transaminase (GOT) in serum, and superoxide dismutase (SOD), catalase (CAT) and reduced glutathione (GSH), membrane bound enzymes like Na + K + ATPase, Ca 2+ ATPase, Mg 2+ ATPase and decreased lipid peroxidation (LP) in heart tissue, indicating the protection afforded by GTE administration.

Pharmacie Globale : International Journal of Comprehensive Pharmacy , 2012,
Abstract: Natural products today are most likely to exist and grow to become even more valuable as sources of new drug leads. This is because of broader degree of chemical diversity and novelty of molecules found in natural products than that from any other source. The oral cavity provides a diverse environment for colonization by a wide variety of micro organisms. The plant under consideration is reported in the traditional literature for treatment of dental disorders. Thus, the aim of this research work was to evaluate extracts of the investigational plant Embelia tsjeriam cottam against dental pathogens. Ethanolic extracts of leaves and roots of the plant were prepared using Soxhlet extractor. The prepared extracts were subjected to phytochemical screening for different active constituents. Dental pathogens were isolated from cavities and tooth tartar of patients. They were characterised morphologically and the prepared extracts were tested for anti microbial activity against these dental pathogens by cup plate method. The root and the leaf extract showed significant activity at a concentration of 100mg/ml against test dental pathogens. Thus the experimental work showed that the roots and leaves extracts of Embelia tsjeriam cottam have promising antimicrobial activity against dental pathogens thus proving their effectiveness in the treatment of various dental diseases thus confirming the traditional claims.

Veterinary World , 2010,
Abstract: A week old 120, Japanese quail chicks were equally and randomly distributed into four different treatment groups (T0, T1, T2 and T3), of three replicates having 10 chicks in each. All the chicks were reared on saw dust litter upto six weeks of age. The chicks in control group-T0 were fed corn-soya based diet with multi- enzyme and group T1, T2 and T3 were fed on diets containing 10, 20 and 30 per cent replaced soybean cake by sunflower cake with multi-enzyme supplementation, respectively. The significant (P< 0.01) differences were noticed between the treatments for weekly live body weights upto sixth week. The blood-biochemicals viz., serum glucose, serum total protein and serum cholesterol level did not varied significantly. It was concluded that inclusion of sunflower cake do not have any adverse effect on blood-biochemical parameters however supplementation of multi-enzyme improves numerically the growth performance of Japanese quails.

Leena Pekkinen, Jaakko Kujala
Technology and Investment (TI) , 2014, DOI: 10.4236/ti.2014.51006
Abstract:

In multinational and complex projects that are often implemented by multiple organizations, the entire projects need to be divided into manageable subprojects. At the same time, all subprojects are needed to be kept aligned with the project goals and targets by integration and coordination. The purpose of this article is to study the role of a particular, work-shop type, collaborative meeting by utilizing the characteristics of an integrative information processing framework. A single case study method was used to observe the practices of collaborative meetings. This study contributes to the project management research by analysing how collaborative meeting practice can be used as a mechanism to reduce uncertainty and equivocality in a large investment project. The results of this study are two folds: Firstly, the case project’s collaborative meetings are described in detail; secondly, the perceived features and procedures of the collaborative meetings in the case project are illustrated showing the role of the collaborative meetings as an integrative tool. Moreover, the perceived integrative characteristics of the collaborative meetings reducing uncertainty and equivocality are presented. This study indicates that collaborative meeting is an integrative mechanism reducing uncertainty and equivocality in a large investment project context.

Risk Management in Project Networks: An Information Processing View  [PDF]
Leena Pekkinen, Kirsi Aaltonen
Technology and Investment (TI) , 2015, DOI: 10.4236/ti.2015.61005
Abstract: Increasingly, projects are executed by networks of organizations. The networked form of organization has many important implications for project risk management. Information processing theories introduce mechanisms for processing information inside organizations as well as among organizations to reduce the uncertainty and equivocality inherently present in international projects. This study aims to examine the risk management practices involved at a project network level through an empirical analysis of one complex large project network executed in a challenging institutional environment. With regard to network level risk management, the paper identifies eight formal information processing mechanisms for implementing risk management: (1) established rules and criteria for the selection of subcontractors at a global level, (2) specification of responsibilities in the contract, (3) formal risk sheet, (4) progress follow-up tool, (5) database for project information, (6) customer reporting system, (7) updated project plan after the project is delayed, and (8) country study team. Personal relationships between parties, personal commitment, experienced individuals, and face-to-face meetings are identified as informal information processing mechanisms used as measures of project risk management to reduce equivocality. We also elaborate the fitness of the mechanisms used for the contextual situations of the project network settings.

PLOS Medicine , 2012, DOI: 10.1371/journal.pmed.1001257
Abstract: Introduction Improving maternal and newborn health in low-income settings requires both health service and community action. Previous community initiatives have been predominantly rural, but India is urbanizing. While working to improve health service quality, we tested an intervention in which urban slum-dweller women's groups worked to improve local perinatal health. Methods and Findings A cluster randomized controlled trial in 24 intervention and 24 control settlements covered a population of 283,000. In each intervention cluster, a facilitator supported women's groups through an action learning cycle in which they discussed perinatal experiences, improved their knowledge, and took local action. We monitored births, stillbirths, and neonatal deaths, and interviewed mothers at 6 weeks postpartum. The primary outcomes described perinatal care, maternal morbidity, and extended perinatal mortality. The analysis included 18,197 births over 3 years from 2006 to 2009. We found no differences between trial arms in uptake of antenatal care, reported work, rest, and diet in later pregnancy, institutional delivery, early and exclusive breastfeeding, or care-seeking. The stillbirth rate was non-significantly lower in the intervention arm (odds ratio 0.86, 95% CI 0.60–1.22), and the neonatal mortality rate higher (1.48, 1.06–2.08). The extended perinatal mortality rate did not differ between arms (1.19, 0.90–1.57). We have no evidence that these differences could be explained by the intervention. Conclusions Facilitating urban community groups was feasible, and there was evidence of behaviour change, but we did not see population-level effects on health care or mortality. In cities with multiple sources of health care, but inequitable access to services, community mobilization should be integrated with attempts to deliver services for the poorest and most vulnerable, and with initiatives to improve quality of care in both public and private sectors.

Abstract: To test an intervention that supports local women as facilitators in mobilising communities for better health care. Community women's groups will build an understanding of their potential to improve maternal and infant health, and develop and implement strategies to do so.Cluster-randomized controlled trial.The intervention will employ local community-based female facilitators to convene groups and help them to explore maternal and neonatal health issues. Groups will meet fortnightly through a seven-phase process of sharing experiences, discussion of the issues raised, discovery of potential community strengths, building of a vision for action, design and implementation of community strategies, and evaluation.The unit of allocation will be an urban slum cluster of 1000–1500 households. 48 clusters have been randomly selected after stratification by ward. 24 clusters have been randomly allocated to receive the community intervention. 24 clusters will act as control groups, but will benefit from health service quality improvement. Indicators of effect will be measured through a surveillance system implemented by the project. Key distal outcome indicators will be neonatal mortality and maternal and neonatal morbidity. Key proximate outcome indicators will be home care practices, uptake of antenatal, delivery and postnatal care, and care for maternal and neonatal illness.Data will be collected through a vital registration system for births and deaths in the 48 study clusters. Structured interviews with families will be conducted at about 6 weeks after index deliveries. We will also collect both quantitative and qualitative data to support a process evaluation.Current controlled trials ISRCTN96256793After a decade of relative stagnation, the child survival agenda has been reinvigorated by a series of calls for action and the agreement of a set of United Nations Millennium Development Goals. The fourth and fifth goals are linked explicitly with maternal and child survival

Genetic engineering for improvement of Musa production in Africa
Leena Tripathi
African Journal of Biotechnology , 2003,
Abstract: Bananas and plantains (Musa sp.) are the most important staple food and source of carbohydrates in many countries of Africa. The production is often constrained by many pests and diseases. In order to augment conventional breeding and to avoid constraints imposed by some pests and pathogens, transgenic approaches are being considered. The development of transgenic Musa plants has been achieved recently using the microprojectile bombardment procedure or Agrobacterium-mediated transformation. The transgenic approach shows potential for the genetic improvement of the crop using a wide set of transgenes currently available which may confer resistance to nematode pests, fungal, bacterial and viral diseases. This article discusses the applications of genetic engineering for the enhancement of Musa production.
