OBJECTIVE To evaluate dental, skeletal, and soft tissue effects during Twin-block treatment. METHODS A systematic search of several electronic databases (Medline, PubMed, Embase, all EBM reviews, and Web of Science) was conducted until July 2013, as well as a limited grey-literature search (Google Scholar). Human cephalometric studies that used a Twin-block appliance in a non-extraction and n...

OBJECTIVE To study the impact of orthodontic treatment on the quality of life in two patient groups, one treated with the twin block appliance and the other with fixed appliances. MATERIALS AND METHODS Ninety-eight patients, aged between 10 and 16 years, were recruited in the fixed (20 males and 29 females) or functional (29 males and 20 females) treatment groups. The oral health-related qual...

In this work a model to estimate the efficiency of natural ventilation in a commercial twin-span greenhouse is presented. A numerical simulation approach was adopted using the theory of three-dimensional computational fluid dynamics (CFD). With this approach, it was able to generate three-dimensional patterns for temperature and airspeed inside the greenhouse, using specific boundary conditions...

BACKGROUND The objective of the present study was to evaluate and compare temporomandibular joint changes especially disk-condyle-fossa relationship following functional treatment of skeletal class II division 1 malocclusion using Twin Block and Bionator appliances. METHODS The total sample consisted of 30 subjects (13 males and 17 females) with class II division 1 malocclusion having mandibu...

Aesthetic improvement is highly valued by patients seeking orthodontic treatment ( Dann et al. , 1995 ). Subjects with a Class II malocclusion are a good example of patients who are referred to orthodontists primarily for aesthetic improvement ( Dann et al. , 1995 ). In growing patients, two-phase treatment of Class II skeletal malocclusions, which includes growth modifi cation with functional ...

The twin-arginine translocation (Tat) system transports folded proteins across the bacterial plasma membrane, including FeS proteins that receive their cofactors in the cytoplasm. We have studied two Escherichia coli Tat substrates, NrfC and NapG, to examine how, or whether, the system exports only correctly folded and assembled FeS proteins. With NrfC, substitutions in even one of four predict...

In Class II, Division I malocclusion is a common problem often associated with mal-relationship of dental bases and mal-alignment of dentition. The approaches to treat Class II, Division I malocclusion include growth modulation, dental camouflage and surgical orthodontics. A 16-year-old female patient with Class II, Division I malocclusion associated with excessive over jet, deep bite, and retr...

The $\mathrm{\ensuremath{\Sigma}}3{112}$ tilt grain boundary (GB) is found in many grains bcc polycrystalline metals due to its low energy and high stability. Moreover, it the coherent of ${112}$ twin. This paper studies interaction a pileup $1/2\ensuremath{\langle}111\ensuremath{\rangle}$ dislocations with GB, extendable twin (TB). results are applied interacting dislocation transformed into G...

To determine “Effect of integrated weed management practices in direct sown finger millet”. The field experiment was conducted during rabi 2022 at South Farm, Karunya Institute Technology and Sciences, Coimbatore. soil the experimental sandy clay loam texture, pH 6.9, level organic content (0.37%), available N (336 kg ha-1), P (91 ha-1) K (261 ha-1). laid out completely randomized block design....

Twin-row ridge cultivation is widely used in soybean planting northern China. In order to find the optimal parameters of agronomy, twin-row planter with subsoiling was designed. Field experiments were conducted evaluate effects plant arrangements and cluster densities on growth grain yield under different tillage treatments. The experiment a randomised complete block design consisting 20 treatm...
