OBJECTIVE The aim of this study was to identify the procedures adopted by Brazilian orthodontists in the following situations: extraction space closure, anchorage control in case of necessary anchorage for group A and frequency of skeletal anchorage use, especially in the upper jaw. METHODS A questionnaire was sent to the e-mail address of all dentists registered in the Brazilian Federal Coun...

Plant root traits are diverse and variable, the way in which they interact has consequences for fundamental functions such as anchorage, or services soil fixation. Here, we characterize mechanical related to anchorage (tensile strength, strain, stiffness toughness) at both intra- inter-specific levels examine how covary with other economics space. We grew twelve herbaceous species from contrast...

Abstract One of the crucial factors that has gained widespread popularity during tunnelling construction process is face stability tunnel mainly depends upon support pressure to be applied at against overburden and surcharge loading acting on earth surface. In this study, different cross sections tunnels been investigated in cohesionless soil (loose medium dense sand) using Finite Element Analy...

We studied whether arsenic, nickel, and chromium compounds that are human carcinogens could induce transformation of cultured primary human diploid foreskin cells (HFC). All nickel compounds tested, PbCrO<, K2Cr2O7, CrO3, Na2HAsO4, NaAsO2, and jV-methyl-A/'-nitro/V-nitrosoguanidine (MNNG) caused significant (p = 0.001) dose-de pendent inductions of anchorage-independent colonies in HFC. kl l.. ...

In orthodontics, anchorage is a prerequisite for the application of therapeutic forces and can limit their successful use. According to the intended treatment goals, desired tooth movements should, therefore, be maximized and undesirable effects minimized. But additional anchorage such as extraand intraoral forces are visible and hence compliance dependent and are associated with the risk of un...

About the Community Anchorage is a combined city-county government that covers Alaska's largest and most important metropolitan area.
