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.
Values and norms that develop in people of Papua tend to discriminate women which can affect the woman health status and may lead to a high rates of maternal and child deaths of Biak tribe in Biak Numfor Regency, Papua Province. This study aims to develop concepts and propositions on women's reproductive health (pregnancy health, healthcare delivery and post-partum health) on Biak tribal culture in Biak Numfor. The research design is qualitative with the ethnometodology approach, symbolic interaction, and Kasper models analogy. Sources of data obtained from informants by interview, observation and documentation. Informants consisted of (1) the macro level, the tribal chief / head of customs, (2) the meso level, the community leaders / traditional leaders, and (3) a micro level, the head of the family / in-laws / parents, informants pregnant women, maternity women informans and informants during childbirth. The results found the concept of loose tribal cultures showed
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.
Purpose: To determine the clinical relevance of determining the semen pH during semen analysis as per WHO (World Health Organisation) standard criteria among the infertile couple attending a tertiary ART (Assisted Reproductive Technology) Centre in South India. Methods: Regular Semen analysis as per WHO standards (2010) Results: The Semen pH value showed no major correlation with other Semen parameters and also varied greatly from the given WHO standard. Conclusion: The semen pH determined during semen analysis is found to have not much relevance for clinical practice. The clinical relevance of semen pH for Azoospermia patient needs to be revised.
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 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
The purpose of this study was to refine Gravitational Insecurity (GI) assessment among Indian Children. GI assessment (original version) was examined with 28 children with GI and matched typically developing children. The results revealed that 9 items (Jumping, height jump, Stand on chair, jumping off chair with eyes closed, forward roll, backward roll, tilt board step, Supine ball-active and supine on ball – passive) were correctly discriminate GI children from typically developing children than the other six items (broad Jump, stick jump, Jump off chair with eyes open, prone on ball, swinging ball, bounced ball catch) . These 9 items were included in revised version of GI assessment. Revised version of GI assessment required 30-40 minutes for administration. It was time consuming to assess Gravitational Insecurity. May benson & Koomar suggested that GI assessment (revised version) has to be refined inorder to avoid time consuming.
This paper assesses the net welfare associated with the adoption of Bench Terraces (BT), Contour Bunds (CB), and Napier Grass Strips (NGS) in the Saba Saba sub-catchment of the Upper Tana catchment in Kenya. An agro-economic survey and informal interviews were conducted in the Saba Saba sub-catchment to elicit farm level quantitative data for the Cost Benefit Analysis (CBA). Financial functions in excel were used to analyze the on-site costs and benefits of adopting the identified SWC technologies on farms with crops such as maize, coffee, and tea. In this research CBA was used as a decision tool after the computation of all cost and benefits were valued in local currency to obtain the Net Present Value (NPV) or net welfare. The results show that investment in SWC measures may not be a feasible short-term option from farmers’ perspective. There is, therefore, a strong case for intervention, especially in the initial years where SWC adoption yields negative returns.
The aim of our study was to analysis a sample parents of tennis players in three different clubs situated in Tunisia and to incorporate the related inherent of the socio-economic factors of these issues and adopted the federal efforts to pout popularization of this sport. In our research we were incorporate for the achievement, the questionnaire as an investigative technique. The analysis focuses on a sample of 100 parents of players tennis clubs in three different situated in Greater Tunis. The questionnaire is, in fact, a set of ordered questions used to collect information’s from a population determined in tennis practice. The multiple choice question has a predetermined range of responses. Four variables were adopted; the socioeconomic level, age, level of studying, quality of population. The results indicate after comparing the responses of the experimental group: It should be noted that parents who take their children to practice courts have different social groups;
