The use of drugs has become a global problem with a large percentage of teenagers around the globe being hooked to these slow poisons. What many people fail to observe many drug addicts will tell you that they began the habit when they were still young.

Characterization of Mineral Phosphate Solubilizing  Gram-positive Bacteria

Most agronomic soils contain large reserves of total phosphorus [P], but the fixation and precipitation of P cause P deficiency, and in turn, restrict the growth of crops severely. Phosphorus replenishment, especially in sustainable production systems, remains a major challenge as it is mainly fertilizerdependent. Though the use of chemical P fertilizers is obviously the best means to circumvent P deficiency in different agroecosystems, their use is always limited due to its spiralling cost. A greater interest has, therefore, been generated to find an alternative yet inexpensive technology that could provide sufficient P to plants while reducing the dependence on expensive chemical P fertilizers. Among the heterogeneous and naturally abundant microbes inhabiting the rhizosphere, the phosphate solubilizing microorganisms (PSM) including bacteria have provided an alternative biotechnological solution in sustainable agriculture to meet the P demands of plants.

Alert Addiction among Young Students in Taif City in  Western Area of Saudi Arabia

This article is a demonstrative study about the problem and size of addiction in western area especially Taif city in Saudi Arabia through applying of international questionnaires guidelines. These questionnaires were used to assess tobacco, alcohol, and narcotics addiction. They were performed on secondary school male students in Taif ,Saudi Arabia, in addition to Roshd and Kafa and population as well. The total sample size for the present study is equal to 2514

Knowledge of Book-Keeping as a Predictor of Academic  Performance in Principles of Accounts among Bu

The major purpose of this study is to find out the extent to which previous knowledge of Book-keeping will predict students’ academic performance in Principles of Accounts 1 (BED 111) at the NCE 100 level in College of Education, Ikere Ekiti, Ekiti State, Nigeria. The study employed an ex-post facto research design with a sample of 371 selected from a population of 708. Three research hypotheses were tested at 0.05 level of significant using T-test, Standard deviation, Multiple regression and Analysis of variance. A finding from the study reveals that previous knowledge of Book-keeping significantly contributes to the prediction of academic performance of students in Principles of Accounts 1 (BED 111) among others. It was concluded that the influence of previous knowledge in teaching/learning process provides the background to framework upon which new learning will be placed. It is recommended that Joint Admission Matriculation Board (JAMB) should properly streamline

Students’ Variables as Predictor of Secondary School  Students’ Performance in Physics

The Students’ Variables as Predictor of Secondary School Students’ Performance in Physics in Ekiti West Local Government Area of Ekiti State, Nigeria was investigated in this study. The study adopted a survey research design of the ex-post facto type. The sample comprised 120 senior secondary school II Physics students drawn from the six secondary schools in Ekiti West Local Government Area of Ekiti state. The instruments used for the study was questionnaire and past academic performance in Physics of the students involved in the study. Two research hypotheses were generated and analysed in the study using Pearson’s Moment Correlation and Multiple regression statistical analysis. Among others, the study revealed that: students‘ variables (study habit, attitude to and interest of students in Physics) are better predictors of students’ performance in Physics, while student gender has no influence on students academic performance (is a poor predictor).

Automatic Template Extraction from Heterogeneous  Web Pages

- In this paper, we will enlist the process of extracting template from heterogeneous Web Pages. Extracting structured information from semi-structured machine readable web pages automatically plays a major role these days, so some websites are using common templates with contents to populate the data for good productivity, Where WWW is the major resource for extracting the information. The problem here is for machines, the templates in the web pages are considered to be harmful since they degrade the performance of web applications due to irrelevant terms in the Template. As a result, the performance of the entire system degrades. Template Detection technique can be used to improve the performance of search engine as well as for classification of web documents. In this paper, we present algorithms to extract templates from a very large number of web pages that are getting generated from heterogeneous templates. Using the similarity of template structures in the documen

Solar power for Wireless Sensor Networks in  Environment Monitoring Applications-A Review

Routing in Wireless Sensor Networks has to take into account the limited battery resources of the nodes. Sensor nodes can also be powered by other energy sources like solar energy. This paper provides a review of Environment monitoring using Wireless Sensor Networks. The issues related to environment sensor networks is highlighted. The real time applications in environment monitoring is presented with emphasis on energy conservation. Furthermore in this paper we address the problem of scavenging energy using solar powered devices.

Experimental investigation on Self-Curing SelfCompacting Concrete by Replacing Natural Sand by Msand

In recent years, self-compacting concrete (SCC) has gained wide use for placement in congested reinforced concrete structures with difficult casting conditions. For such applications, the fresh concrete must possess high fluidity and good cohesiveness. In this present study, the effect of replacing the cement, fine aggregate and coarse aggregate by constant replacement of silica fume, Manufactured sand (JSW) replacement of 0%, 10%, 20%, 30%, 40% and light weight aggregate replacement of 10%, 15%, for internal curing respectively and their combinations of various proportions on the properties of different mixes of M40 grade has been compared with normal self compacting concrete by conventional curing method. In this study fresh property and hardened properties of the different mixes of concrete were determined. From the present study the test result showed that for fresh concrete all the mixes satisfies the EFNORC standard values.

Effect of Plant Products on Morphological Parameters of  Tukra Affected Mulberry Leaves

Tukra is one of the major problem in mulberry growing areas and it is caused by pink mealy bug Maconellicoccus hirsutus which affect both the quality and yield of mulberry leaf. In general the tukra- diseased leaves showed high moisture content compared to normal healthy leaves. A preliminary attempt has been made to know the effect of plant extracts of natural pesticide origin on moisture content, loss and retention capacity of tukra affected mulberry leaves. The seed kernel and leaf extracts of Azadirachta indica, Pongamia pinnata, Madhuca longifolia and only leaf extracts of Lantana camara, Adathoda vasica were directly used as a foliar spray on M-5 mulberry variety under field conditions. The results revealed that the tukra affected leaves showed high moisture content (75.92%) compared to normal healthy leaves (71.32%). The moisture content was more in NSKE @ 4% (73.83%) PSKE @ 4% (73.80%), MSKE @ 4% (73.30%), and lowest was recorded from MSKE @ 2% (71.76%)

Leadership style of Nurse Managers

Leadership style is phenomenon which affects the productivity and quality nursing care. There is a lack of research studies in this area in Sri Lanka. The aim of this study was to examine the nurses’ perception about their nurse managers’ leadership style. The study sample comprised 160 nurses using simple random sampling. The research instruments were Demographic Data Recording Form and the Perceived Leadership Form Questionnaire. The reliability coefficient of the Perceived Leadership Form Questionnaire was 0.86 and the content validity index of was .91. Data were analyzed using descriptive statistics. Nurses perceived their managers’ leadership style as transformational (Mean = 3.35, SD =0.64), and transactional leadership as (Mean = 3.25, SD =0.45). The results of the study showed that nurses perceived their managers’ leadership style as transformational. The study provides the opportunity for nurse managers to look into their nursing staff by examining
