Association of Vitamin D Deficiency with Hypertension in Uninsured Women
Vitamin D deficiency is an epidemic in the United States. Uninsured women are at high risk due to a lower intake of vitamin D and limited sun exposure. We examined the association between vitamin D deficiency and hypertension in 96 uninsured women at a County Free Medical Clinic in urban Michigan. Questionnaires were used to obtain information about demographics, medical history including hypertension, and dietary habits. Measurements including blood pressure and serum 25(OH)D level were also collected. Prevalence of hypertension was higher in subjects with 25(OH)D less than 50nmol/l compared with others (85% vs. 27.3%, p = 0.014). For every 1 nmol/L decrease in serum 25(OH)D, there was an increase in the systolic and diastolic blood pressure by 0.20 (p =0.006) and 0.13 (p =0.003) mm of Hg respectively. These results demonstrate a high prevalence of hypertension in the vitamin D deficient, uninsured female population
Do dot coms add value : a preliminary study of the market capitalisation of Australian and Indian telecoms and banking sectors
E-Business is increasingly reshaping the way businesses operate across the globe. Globally, businesses in the banking and telecoms sectors have been re-engineering their value chains by adopting e-Business presence by means of dot com launches. The second half of the 1990s, however, saw both the rise and subsequent collapse of dot com entities as a major focus of investment interest, with consequent speculation over the viability of this corporate vehicle. The perceived increase in market capitalisation by means of these ventures during the boom period is now not so certain. In this paper, we report the results of a preliminary study which investigated the impact of dot com launches on market capitalisation within the banking and telecoms sectors of Australia and India.<br /
Clustering Algorithm Combined with Hill Climbing for Classification of Remote Sensing Image
Clustering is an unsupervised classification method widely used for classification of remote sensing images. As the spatial resolution of remote sensing images getting higher and higher, the complex structure is the simple objects becomes obvious, which makes the classification algorithm based on pixels being losing their advantages. In this paper, four different clustering algorithms such as K-means, Moving K-means, Fuzzy K-means and Fuzzy Moving K-means are used for classification of remote sensing images. In all the traditional clustering algorithms, number of clusters and initial centroids are randomly selected and often specified by the user. In this paper, a hill climbing algorithm for the histogram of the input image will generate the number of clusters and initial centroids required for clustering.  It overcomes the shortage of random initialization in traditional clustering and achieves high computational speed by reducing the number of iterations. The experimental results show that Fuzzy Moving K-means has classified the remote sensing image more accurately than other three algorithms.DOI:http://dx.doi.org/10.11591/ijece.v4i6.660

A Comparative Evaluation of the Release of Metal Ions from Round and Rectangular Superelastic Niti Wires of Three Different Manufacturers: An In Vitro study
Nickel titanium wires are the routinely using archwires in orthodontics. The two wires which are used in the initial and final stages are round and rectangular wires respectively. Biocompatibility of any dental material is now a fundamental requirement of successfill clinical behavior in oral cavity. NiTi is a universal wire, Nickel in NiTi is capable of eliciting toxic and allergic responses and can produce more allergic reactions than any other metal elements. So, nickel titanium orthodontic arch wire with a good properties including corrosion resistance is essential to its biocompatibility. The metal ions leaching from orthodontic wires cannot be fully evaded; but it is possible to use materials with lower amounts of ions leaching in the mouth. It was proven that the
amount of ions, leached from orthodontic wires in saliva was less than the toxic concentrations, which is below the critical value necessary to induce allergy and less than the daily dietary intake levels. The purpose of this study is to determine the amount of Ni and Ti ion release from NiTi wires of three different manufactures and to check whether the leached metal ions is lower than the daily dietary intake.
METHODS:
The study was performed by immersion of the samples in artificial saliva at various time intervals and Ni and Ti release was quantified with the use of an inductively coupled plasma mass spectrometry. In this study superelastic NiTi Archwires of three different manufactures which is in two shapes Round and Rectangular of commonly using dimensions 0.016 and 19x25 respectively of 7 inches long are used in this study. The testing solution used in the study is artificial saliva buffer solutions.
PROCEDURE:
Each wires separately dipped into 126 polypropylene beakers containing 50 n11 of buffer solution. Then incubate and quantify the ions leached at T1=1 hour, T2=24 hour, T3=1 week, T4=3 week using the software Thermoscientific QtegraTM Intelligent Scientific Data Solution Software (ISDS) which is attached to the ICP MS instrument. This shared software approach provides control and data processing for a range of elemental and isotopic analysis technologies The output is numerical, and provided in counts per second i.e., how much Nickel and Titanium (mass—ion ratio) is released per second.
RESULTS:
From the findings of present study, revealed that Round wire shows least metal ion leaching than rectangular wire. This may differ according to the manufacturers choice. Least immersion time shows greatest release of metal ions and Group Ia is better than all other groups.
CONCLUSION:
When comparing three manufactures, Group I shows least Ni and Ti ion leaching among other two groups. When comparing round and rectangular wires; round wires shows less ion release than rectangular wires. The least Ni and Ti ion release is shown by Group Ia at all time periods. The highest Ni and Ti ion release is shown by Group IIIb at a11tirne periods .At each immersion time, T1 shows 1east Ni and Ti ion release than other time periods, which gradually increases with immersion period. The average amount of ions leached per day from round and rectangular of
three manufactures was well below the tolerable daily dietary intake level
