pituitary suppression by depot gnrh agonist may be excessive for ovarian stimulation. this study compares the efficacy of a single half-dose depot triptorelin and reduced-dose daily buserelin in a long protocol icsi/et. methods: a total of 182 patients were randomized into two groups using sealed envelopes. pituitary desensitization was obtained in group 1 (91 patients) with half-dose (1.87 mg)...

Short cracks tend to develop at high and irregular rates compared macroscopic cracks, making the prediction of fatigue life a challenging task. In this work, numerical framework combining crystal plasticity model Extended Finite Element Method (XFEM) is applied study slip-controlled short crack growth in polycrystal superalloy RR1000. The calibrated from experiments used evaluate paths rates. T...

Autoagglutinable strains of Vibrio cholerae O1 (seven nonfimbriate strains and one fimbriate strain) were transformed to obtain resistance to ampicillin. Two distinct mechanisms were found in these strains. One was operating in nonfimbriate strains by reducing OmpU protein production and the other was operating in a fimbriate strain (Bgd17) by newly overproducing cpxP protein. The twitching mot...

We used computer simulations to study spontaneous strain localization in granular materials, as a result of symmetry breaking non-homogeneous deformations. Axisymmetric triaxial shear tests were simulated by means of standard three-dimensional Distinct Element Method (DEM) with spherical grains. Carefully prepared dense specimens were compressed between two platens and, in order to mimic the ex...

Strain measurements must often be made in the presence of electric and/or magnetic fields which can superimpose electrical noise on the measurement signals. If not controlled, the noise can lead to inaccurate results and incorrect interpretation of the strain signals; and, in severe cases, can obscure the strain signals altogether. In order to control the noise level, and maximize the signal-to...

Atomically thin two-dimensional (2D) alloys have attracted wide interests of study recently due to their potential in flexible electronic and optoelectronic applications. In particular, monolayer transition metal dichalcogenide (TMD) emerged as unique 2D semiconductors with tunable bandgaps, by means alloying. However, response surface electrical barrier height strain for TMD alloys–electrode i...

Although tics are the defining feature of chronic tic disorders (CTD), many children experience comorbid internalizing and externalizing problems that contribute to impairment across several domains, including family functioning. The current study examined clinical correlates and predictors of caregiver strain in parents of children with CTD. Participants were 123 children and adolescents diagn...

Voltage-modulated magnetism in magnetic/BiFeO3 heterostructures can be driven by a combination of the intrinsic ferroelectric-antiferromagnetic coupling in BiFeO3 and the antiferromagnetic-ferromagnetic exchange interaction across the heterointerface. However, ferroelectric BiFeO3 film is also ferroelastic, thus it is possible to generate voltage-induced strain in BiFeO3 that could be applied o...

Background Microvascular obstruction is a major problem after reperfusion therapy of AMI. A recent study reported that longitudinal and circumferential strain after reperfusion therapy is an excellent predictor of left ventricular (LV) dysfunction in patients with anterior wall AMI [1,2]. In the current MRI investigation, we adapted a method routinely used in echocardiography for measuring LV, ...

A combination of the crown gall biocontrol strain K-84 and another antagonist JH-l was better than K-84 alone in controlling some Agrobacterium strains. Strain K-84 surprisingly controlled some resistant Agrobacterium strains when heavy concentrations of K-84 were used. Strain K-84 could control sensitive strains of Agrobacterium up to 48 hr. after wounds were inoculated with the pathogen at te...
