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

A total of five new metal complexes derivatives of 2-(6-methoxynaphthalen-2-yl) propanoate, HL with the metal ions (Cd(II), Zn(II), Sn(II), Ni(II) and Cu(II)) have been successfully prepared in alcoholic medium. The complexes were characterized quantitatively and qualitatively by using micro elemental analysis, FTIR spectroscopy, UV-Vis spectroscopy, magnetic susceptibility and conductivity measurements. From the spectral measurements, monomer structures for the complexes were proposed, square planar geometry was proposed for the copper complex. The other complexes were proposed to be tetrahedral.

Abstract

A mercury porosimeter has been used to measure the intrusion volume of the three types mercury positive lead acid-battery plates. The intrusion volumes were used to calculate the pore diameter, pore volume, pore area, and pore size distribution. The variation of the pore area in positive lead acid-battery plates as well as of the pore volume has the following sequence. Paste positive > Uncured positive > Cured positive

Abstract

Aims: To determine the level and angulation of the occlusal plane of the artificial dental arch by measuring the level and angulation of the occlusal plane of completely dentulous subjects and to find the relation of these measurements to some of the vertical facial and intra oral dimensions. Materials and Methods: The sample of the study consisted from 54 completely dentulous adult subjects (24 female and 30 male) with class 1 normal occlusion aged 19–24 years. Dental casts were taken for each subject, the level and angulation of the occlusal plane, vertical facial, and intra oral dimensions were measured using digital vernier caliper and protractor. The data were analyzed with statistical package for social science program. Results: Sexual differences were found in the intra and extraoral measurements. Most of the measurements dealing with the occlusal plane level and angulation were correlated with each other and with facial measurements. Conclusions: The level and angulation of the occlusal plane of the maxillary and mandibular dental arches as measured on the dental casts are higher in maxilla than in mandible and the intra and extraoral vertical facial measurements are greater in male than female.

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.

Abstract

Carbon monoxide (CO) plays an important indirect greenhouse gases due to its influences on the budgets of hydroxyl radicals (OH) and Ozone (O3). The atmospheric carbon monoxide (CO) observations can only be made on global and continental scales by remote sensing instruments situated in space. One of instrument is the Measurements of Pollution in the Troposphere (MOPITT), which is designed to measure troposphere CO and CH4 by use of a nadir-viewing geometry and was launched aboard the Earth Observing System (EOS) Terra spacecraft on 18 December 1999. Results from the analysis of the retrieved monthly (1ºх1º) spatial grid resolution, from the MOPITT data were utilized to analyze the distribution of CO surface mixing ratio in Iraq for the year 2010. The analysis shows the seasonal variations in the CO surface fluctuate considerably observed between winter and summer. The mean and the standard deviation of monthly CO was (172.076 ± 62.026 ppbv) for the entire study period. The CO value in winter was higher than its values in summer season and its values over Industrial and congested urban zones higher than its values in the rest of regions throughout the year. Maximum values occurred in the northern region (234.105 ppbv) on February at Erbil, were attributed to the increased human activity, geographic nature of the areas and climatic variations. The elevation of CO values on the south-eastern region during the June - November period was due to the emissions from the oil extraction and the burning of agricultural residues in the paddy fields. A greater draws down of the CO occurs over pristine desert environment in the western region (110.047 ppbv) on July at Al Anbar (41.5°log. × 32.5°lat.). The monthly CO surface VMR maps for 2010 were generated using kriging algorithm technique. The MOPITT data and the Satellite measurements are able to measure the increase of the atmosphere CO concentrations over different regions.
