The accuracy of determining left ventricular function from echocardiography was assessed in 26 children (group I) with cineangiographically-determined normal left ventricular volume (LVV) and 28 children (group II) with large left ventricular volumes. Conventional LV echo dimensions were compared to the cineangiographic LV anterior-posterior minor axis (LVmA) and LVV. Very good correlations wer...

The title compound, C5H9BrN4O, was obtained as a minor by-product in the synthesis of 4-di-methyl-amino-1-methyl-1,2,4-triazolin-5-one. Except for the methyl groups of the 4-dimethylamino moiety, all the non-H atoms lie on a crystallographic mirror plane." In the crystal, the mol-ecules are linked by C-Br⋯O=C inter-actions [Br⋯O = 2.877 (2) Å, C-Br⋯O = 174.6 (1)°] into infinite chains in the c-...

High-angular-momentum states in 108Cd were populated via the (64)Ni((48)Ca,4n) reaction at a beam energy of 207 MeV. Gamma rays were detected using the Gammasphere array. A rotational band has been observed with a dynamic moment of inertia and deduced lower limit of the quadrupole moment suggesting a major-to-minor axis ratio larger than 1.8:1, placing it among the most deformed structures iden...

OBJECTIVE Growth retardation in children with b-thalassemia major is multifactorial. Some etiologies described for this condition are hemochromatosis, disturbed growth hormone (GH) / insulin growth factor-1 (IGF-1) axis, undernutrition and hypermetabolism. It has also been proven that growth retardation is present in b-thalassemia major children despite regular transfusion and chelation. Our ai...

Optical Fabry-Perot interferometer sensors based on inner air-cavity is featured with compact size, good robustness and high strain sensitivity, especially when an ultra-thin air-cavity is adopted. The typical shape of Fabry-Perot inner air-cavity with reflection mode of operation is elliptic, with minor axis along with and major axis perpendicular to the fiber length. The first reflection surf...

A new method to determine left ventricular (LV) ejection fraction (EF) with wide-angle, two-dimensional echocardiography (2-D echo) has been developed using the parasternal long-axis, apical four-chamber and apical long-axis views. End-diastolic and end-systolic measurements of LV short axes at the base and mid-LV cavity in the parasternal long-axis view and at the upper, middle and lower third...

With the rapid development of high-performance fibers such as carbon, enhanced glass in structural applications, use fiber-reinforced composite (FRC) materials has also increased many areas. Liquid molding (LCM) is a widely used manufacturing process manufacturing; however, impregnation resin reinforcing during processing poses significant issue. The optimization related to tow deformations fib...

purpose : to determine the association between astigmatism and spherical refractive error in a clinical population methods : in this cross-sectional study, 2,000 patients who presented to our optometry clinic were enrolled. all were tested for objective refraction with a nidek ar-310a auto refractometer, and non-cycloplegic refraction. for those under 15 years of age, cycloplegic refraction was...

grading science and grading equipment for many kinds of sea products are growing rapidly in developed communities and variety of grading equipment can be found in most of the large fishery units. computer vision has the potential to be used as a precise method for recognition and assessment of apparent characteristics. in this study, machine vision technology was used to sort fish based on spec...

salivary  gland  tumors  accounts  for  less  than  1%  of  all  tumors.  minor  salivary  gland  tumors (msgts) are uncommon and make up about 10% of all salivary gland neoplasms. the clinical and histopathological distribution of these tumors vary geographically. a case of a 38 yr old man with a minor salivary gland mass at chin region isreported here. the tumor invaded into the anterior surf...
