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

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).

Improving Wireless Sensor Network Performance Using  BigData and Clustering Approach

Well-organized big data get together in the densely distributed sensor networks is, therefore, a challenging research area. One of the most effective solutions to address this challenge is to utilize the sink node’s mobility to facilitate the data gathering. While this technique can reduce energy consumption of the sensor nodes, the use of mobile sink presents additional Challenges such as determining the sink node’s trajectory and cluster formation prior to data collection. In this paper, we propose a new mobile sink routing and data gathering method through network clustering based on modified ExpectationMaximization (EM) technique. In addition, we derive an optimal number of clusters to minimize the energy consumption. The effectiveness of our proposal is verified through numerical results.

NANO… one billionth of one and one third of micro ,to be precise 10-9m. Nanotechnology is much discussed these days as a emerging frontier – a realm in which machines operate at scales of billionth a metre. It is actually a multitude of rapidly emerging technologies based upon the scaling down of existing technologies to the next level of precision and miniaturization. In the field of nano technologies researchers are enthusiastic about its potential applications in fields such as energy, medicine, electronics, computing and materials. Of late, one of the emerging aspects dealing Nanotechnology in mechanical field is the internal combustion engine on a nano scale, which we have chosen as our area of interest. Heat engines have evolved from external combustion engines to internal combustion engines and the hot off the block is the nano internal combustion engine.

Natural Environment of Cold Desert Region Zanskar  (Ladakh)

The study of man-environment relationship has great importance today. Human beings interact with their environment from the early stage of development to modern lives. In the process of this interaction they modify and transform environment. Environment plays determining role in the early stages of development where society essentially adapts itself to the limits laid down by it. As development proceeds onwards, the subservience to it gets progressively reduced and the process of cooperation and interaction begins. Present paper is based on analysis of secondary data published by different sources. Arc viewGIS 10 has been used to construct various kinds of maps in this paper. The natural environment of Zanskar presents a very harsh and fragile system. This region experiences heavy snowfall during winter caused by the western disturbances. Zanskar Tehsil is an underdeveloped area where existing use of natural resources is limited due to the low level of technology

Performance Evaluation of Zero-Till Ferti-Seed Drill in  Comparison to Conventional and Reduced Till

Rice–wheat cropping system is very common in India. It contributes to over 70% of total food grain production in the country with an area of 12 M ha under this cropping system. However, it is estimated that under rice and wheat crops separately the area is 42.31 and 22.98 M ha respectively. Looking to the above facts a study at farmer’s field of Ambedkar Nagar district was under taken to evaluate the performance of zero-till seed cum ferti-drill along with other system of wheat seeding. The zero-tillage technique may be adopted successfully for seeding to grow wheat after rice by using zero-till ferti seeddrill (ZTFDS) developed at GBPUA&T, Pantnagar and now manufactured commercial. Although this method of wheat seeding using zero-till seed cum ferti drill is becoming very popular in Haryana and Punjab states but it is not popular in U. P. particularly in central Uttar Pradesh. The zero-tillage sowing was found to be most time saving (88%) and energy efficient (79%)

Analysis of structural features and classification of  Gujarati consonants for offline character rec

Wide range of applications and numerous other complexities involved in character recognition (CR) makes it a continuous and open area of research. Feature selection and classification plays major role in achieving higher accuracy for character recognition. In the era of digitization its compelling need to have CR system for regional script. This paper presents analysis of structural features and its classification for consonants of Gujarati script. Each character has certain characteristics which distinguishes it from other characters. Gujarati consonants are analyzed for eight such structural features and on the basis of it characters are categorized into twenty groups. Further Paper proposes decision table to classify characters based on structural features.

Cervical lymphadenopathy in a Child – An unusual  presentation of filariasis

Clinical manifestations of lymphatic filariasis depend on the area of lymphatic involvement and the duration of infection. An eight year old child presented with right cervical lymph node. Fine needle aspiration cytology (FNAC) with 22 Gauge needle from the lymph node revealed multiple coiled larvae of Wuchereria bancrofti in a background of reactive lymphoid cells with eosinophils. Diagnosis of right cervical Bancroftian lymphadenopathy was made. The case was followed by excisional biopsy of the lymph node and hence was confirmed histopathologically. We report this case because cervical lymphadenopathy is a rare presentation of filariasis in children.

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
