Sonographic evaluation of masseter muscle thickness in bruxist and non-bruxist subjects
...Show More Authors

Background: Masseter muscle is a jaw closing muscle of the mandible involved in Para functional habits; which include lip and cheek chewing, fingernail biting, and teeth clenching or bruxism which can be classified as awake or sleep bruxism. Patients with sleep bruxism are three to four times more likely to experience jaw pain and limitation of movement than people who do not experience sleep bruxism. The aim of this study is to measure the thickness of the masseter muscle in bruxist subjects and compare it with non-bruxist subjects by using sonography. Materials and Method: Forty Iraqi subjects with age ranged (20-40) divided into two groups according to the presence of bruxism. Clinical examination was made and masseter muscle thickness measured for both groups using sonography. Results: For bruxist subjects the mean thickness of masseter muscle in relaxation and clenching were (11.7 ± 1.4 mm) and (16.4 ± 1.3 mm). For non bruxist subjects were (11.2 ± 0.4 mm) and (13 ±0.3 mm) respectively. There was an extremely high statistical significant difference in masseter muscle thickness under clenching between bruxist and non bruxist subjects ( it was higher in bruxist group). Masseter muscle thickness under relaxation was significantly lower than that under clenching for both groups. Also there was a positive correlation between masseter muscle thickness and muscle function in bruxism situation. Conclusion: Masseter muscle in bruxist subject was thicker when compared to non-bruxist subject. Masseter muscle thickness was found to be positively correlated with increasing muscle function. The findings of this study indicate that the functional capacity of the masseter muscle affected by bruxism and may be considered as one of the factors influencing muscle thickness.

Evaluation of Isolated Compounds Activity from Convolvulus Arvensis Against Algae
...Show More Authors

This study includes isolation, purification, and identification of algae from different aquatic environments in Baghdad city. Nine unialgal cultures were obtained. These algal cultures included 6 species of blue-green algae (Microcystis aeruginosa, Microcystis flos-aquae, Oscillatoria limnetica, Nostoc carneum, Westillopesis prolifica, Mastigocluds lamiosus), and 3 species of green algae (Mougeotia sclaris, Scenedesmus dimorphus and Chlorella vulgaris). In addition that aerial parts from Convolvulus arvensis were collected. Terpens, alkaloids and phenols were extracted of mentioned plant, and the antialgal activity of extracts types were evaluated in 3 concentrations (5, 10, and 20 mg/ml) by wells and diffused in the agar media.

Flexural Moment Capacity Evaluation of Reinforced RPC Two-way Slabs
...Show More Authors

The aim of this paper is to determine the flexural moment capacity of Reactive Powder Concrete (RPC) two-way slabs based on three models proposed by previous studies (Model 1, Model 2, and Model 3). The results obtained from these models were compared with those obtained from experimental work to check the accuracy and the applicability of the adopted theoretical models. The experimental program included the testing of three simply supported RPC two-way slabs (1000x1000x70) mm each. The tested specimens had identical properties except their steel fibres volume ratios (0.5 %, 1 %, and 1.5 %). The comparison with the experimental data showed that (Model 3) is the most suitable one among the three models. Model 1 was found to underestimate the

Surface Free Energy for the Evaluation of Asphalt Binder Stripping
...Show More Authors

Stripping is one of the major distresses within asphalt concrete pavements caused due to penetration of water within the interface of asphalt-aggregate matrix. In this work, one grade of asphalt cement (40-50) was mixed with variable percentages of three types of additives (fly ash, fumed silica, and phosphogypsum) to obtained an modified asphalt cement to resist the effect of stripping phenomena .The specimens have been tested for physical properties according to AASHTO. The surface free energy has been measured by using two methods namely, the wilhelmy technique and the Sessile drop method according to NCHRP-104
procedures. Samples of asphalt concrete using different asphalt cement and modified asphalt cement percentages(4.1,4.6 an

Evaluation of breast mass excision by 810 nm diode laser
...Show More Authors

Breast mass is by far the most important clinical problem that concerns the breast today. This study was carried out to evaluate diode laser as a cutting tool in breast mass excision and as a hemostatic tool for coagulation during surgery. Using 810 nm diode laser with optical fiber 600μm in diameter of conical tip, udder (cow's breast) tissue, and three female patients (mean age of 35.5 y with clinically palpable breast mass) had been used in this study. The patients were followed up regularly postoperatively. In preliminary work on udder tissue, the power needed for cutting and excision was 15W (power density= 5.3 kW/cm2). The time consumed for excision of a piece of udder tissue, 40×10×3 mm in dimensions was 5 min. The depth range

Evaluation of some plant secondary metabolites activity to control algae
...Show More Authors

This study includes isolation , purification and identification of algae from different
aquatic environments in Baghdad.
Two different plant species belonging to different families were selected which were
Citrilluscolocynthus and Cordiamyxa for their fruits and fruits samples respectively.
Crude extracts were extracted from each plant and their antialgal activity were
evaluated.Different concentrations (5,15,25) mg/ml of these extracts were prepared
and their antagonistic activity was studied, and the resulted inhibition effects in ( %)
of concentration of chlorophyll(a) after 12 days was evaluated.
Results showed that Chloroccumhumicola was the most sensitive to these extracts.
However, Anabaena circinalis wa

Performance Evaluation of Roughened Solar Air Heaters for Stretched Parameters
...Show More Authors

Artificial roughness applied to a Solar Air Heater (SAH) absorber plate is a popular technique for increasing its total thermal efficiency (ηt−th). In this paper, the influence of geometrical parameters of V-down ribs attached below the corrugated absorbing plate of a SAH on the ηt−th was examined. The impacts of key roughness parameters, including relative pitch p/e (6–12), relative height e/D (0.019–0.043), angles of attack α (30–75°), and Re (1000–20,000), were examined under real weather conditions. The SAH ηt−th roughened by V-down ribs was predicted using an in-house developed conjugate heat-transfer numerical model. The maximum SAH ηt−th was shown to be 78.8% as predicted under the steady-state condition

Laboratory Evaluation of Botteled Drinking Water Collected from Basra City
...Show More Authors

    Forty-four  bottles  of drinking water  were collected from the local markets of Basra City and stored in the laboratory refrigerator  at 4ºC until the physical, chemical and biological measurements were carried out. The results showed a discrepancy in the compatibility of the specifications written on the drinking water  bottle  label with the sample measurements as well as the variation in the results with the Iraqi standards for bottled water.  The percentage of bottled water that is not safe for drinking  was 88.5% of the total samples of the study. This value is high and an indication of lack of control over marketing  from the imported or produced in the local labs, s
