Abstract

This study is dedicated for observing and studying sunspots in the visible andnear infrared regions. Visible and near infrared CCD solar imaging system employing5 inch reflecting telescope is used. The obtained visible and near infrared solar imagesduring the period 01-31, January 2007, and their measurements are presented andcompared.Images obtained with the wavelength 850 nm show sunspot groups of sharp contrastcompared with the visible spectrum images. This leads to larger values of solaractivity measurements R and larger daily total sunspots groups areas . According toMcIntosh sunspot classification the frequency of occurrence among the allowed typesof sunspot groups is the same in the both regions. However , the adoption ofwavelength 850 nm is recommended for reliable sunspot observation and calculation .

Abstract

Background: The purpose of this study was to assess mandibular ramus height and to assess the relationship of ramus heightwith various craniofacial and dental measurements in a sample of Iraqi adults with skeletal and dental Class I.Materials and method: The sample consisted of 95 Iraqi adults (54 females and 41 males) having normal occlusion andClass I skeletal pattern aged between 18 and 31 years. Each individual was subjected to clinical examination and digital truelateral cephalometric radiography. The radiographs were analyzed using AutoCAD 2007 software computer program to de- termine ten linear and seven angular measurements. Descriptive statistics were obtained and independent samples t-test wasperformed to evaluate the gender differences, while Pearson’s correlation coefficient test was used to identify correlationsbetween ramus height and other measurements.Results: All linear measurements were significantly higher in males, while angular measurements showed non-significantdifferences between males and females, except for SN-MP, SN-PP, and N-S-Ar angles which were significantly higher in fe- males than in males. For both genders, there were significant positive correlations between ramus height and posterior facialheight, maxillary and mandibular molar dentoalveolar heights, while there were significant negative correlations with SN-MP,PP-MP, and Ar-Go-Me angles. Ramus height in females showed a significant positive correlation with N-S-Ar angle, and asignificant negative correlation with S-Ar-Go angle.Conclusions: Ramus height was directly correlated with intermaxillary space in the posterior region, and inversely correlatedwith angles of mandibular rotation.

Abstract

The rotational (TR) temperature of N2 molecules, which is an inductor to gas temperature, was measured in atmospheric pressure micro-plasma jet in He with trace amounts of O2 excited by radio-frequency (RF) power. The influence of different parameters such as input RF power to the plasma, different O2 admixtures ratio and the RF pulse modulation frequency, on the gas temperature Tg was investigated. The results show that the control of the operating conditions of the plasma jets enables the tailoring of gas temperature.
