A 2-year-old Indian girl was referred with symptoms of biliary colic and obstructive jaundice of 3 weeks’ duration. Abdominal ultrasonography revealed dilation of intrahepatic biliary radicles, a distended gallbladder, and a dilated common bile duct (CBD) of 15mm (normal diameter up to 6mm) containing multiple ill-defined, oval, hyperechoic shadows near the lower end (▶Fig. 1). Magnetic resonan...

The severe bone destruction and resorption that can occur in osteoarthritis of the temporomandibular joint (TMJ) is associated with significant pain and limited joint mobility. However, there is no validated method for the quantification of discrete changes in joint morphology in early diagnosis or assessment of disease progression or treatment effects. To achieve this, the objective of this cr...

Calculus consists of mineralised dental biofilm on the surfaces of teeth and dental prosthesis, the location of which can be detected by using a periodontal or an electronic probe. Detection of subgingival calculus is critical for successful treatment outcome in the management of periodontal patients. The aim of this study was to detect subgingival calculus using manual and electronic probe and...

OBJECTIVES To evaluate and compare the influence of posterior gummy smile on the perception of smile esthetics by orthodontists, general-dentists and laypersons. STUDY DESIGN A frontal photograph of a smile with normal gum exposure was chosen and manipulated digitally using Adobe Photoshop C3 to generate three further images with posterior gum exposure of 4, 6 and 8mm. These four images were ...

Due to the rapid evolution in electronics and wireless communication, demand for portable electronic devices operating at different frequency bands multiple applications has been increased. Frequency reconfigurable antennas play an important role communication. In our proposed method we designed a micros trip patch antenna using HFSS software order increase return losses. The substrate used thi...

Les carcinomes épidermoides (CE) sont les cancers cutanés les plus fréquents après les basocellulaires. Ils touchent les sujets à partir de 60 ans. Les principales lésions cutanées pré-cancéreuses sont: les kératoses actiniques, les cicatrices de brûlures, traumatismes. Le CE évolue sous une forme ulcéro-bourgeonnante ou superficielle. L’évolution se fait de proche en proche ou par voie hématog...

The joining of dissimilar 6mm thickness plates AA6082 & AA5083 was carried out using the friction stir welding (FSW) technique. process parameters are optimized Taguchi L9 orthogonal design experiments. Where rotational speed (600, 900, 1200 rpm), travel (60, 90, 120 mm/min), and tilt angle (0, 1, 2◦ ) were taken into consideration. optimum determined with reference to tensile strength, yield s...

Based on Fluent software, a mathematical model of thermosyphon pump is established and numerical simulation carried out to study the influence riser tube length, diameter immersion ratio liquid lifting capacity efficiency. The results showed that: volume increased with increase ratio, whereas efficiency trend increasing followed by decreasing. highest for 340mm long, 6mm achieved when 0.35. Wit...
