OBJECTIVES The aim of this survey was to determine how a sample of dentists working in general dental practice in the UK sought to restore the mouths of patients who had shortened dental arches (SDAs). STUDY DESIGN A survey was conducted over a period of six months on four commercial dental laboratories. Cases of SDAs comprising the anterior teeth and 2 to 4 premolars were examined; dental pr...

Motivation This work addresses two common issues in building classification models for biological or medical studies: learning a sparse model, where only a subset of a large number of possible predictors is used, and training in the presence of missing data. This work focuses on supervised generative binary classification models, specifically linear discriminant analysis (LDA). The parameters a...

Abstract The difference between physical activations (by sonications) and chemical ammonia) on sawdust biochar has been investigated in this study by comparing the removal of Cu(II) ions from an aqueous medium adsorption (SD), sonicated (SSD), ammonia-modified (SDA) with stirring at room temperature, pH value 5.5–6.0, 200 rpm. was prepared dehydrations wood reflux sulfuric acid, formed activate...

Histidine kinases are used extensively in prokaryotes to monitor and respond to changes in cellular and environmental conditions. In Bacillus subtilis, sporulation-specific gene expression is controlled by a histidine kinase phosphorelay that culminates in phosphorylation of the Spo0A transcription factor. Sda provides a developmental checkpoint by inhibiting this phosphorelay in response to DN...

The Shortened Dental Arch (SDA) concept introduced as early as 1981 by Kayser and was accepted by a great majority of dentists but not widely practiced. The SDA comprising anterior and premolar teeth in general fulfill the requirements of a functional dentition. Patients’ needs and demands vary much and should be individually assessed but the SDA concept deserves to be included in all treatment...

A novel method named as submicron-dot-array (SDA) doping is developed for the fabrication of low-temperature polycrystallinesilicon thin film transistors (TFTs). All electrical parameters are improved by employing SDA structure. It is worth mentioning that the mobility of fabricated device is 4 times of conventional TFTs. The proposed SDA method has great potential for system-onpanel applications.

There is a longstanding debate about the status of the principle Simplification of Disjunctive Antecedents (SDA), according to which a counterfactual with a syntactically disjunctive antecedent [(φ ∨ψ) > χ] entails a conjunction of counterfactuals [(φ > ψ)∧(ψ > χ)]. This principle is highly intuitive for most examples that have been considered, but it has also been claimed to be subject to empi...

AIM to study the activity of antioxidant enzymes and to evaluate an intensity of prooxidant processes in sarcoma 37 (S37) cells during tumor development and under influence of sodium dichloroacetate (SDA). METHODS Activity of total superoxide dismutase (SOD), SOD isoforms, catalase (Cat), glutathione peroxidase (GP), and glutathione reductase (GR), as well as content of reduced glutathione (G...

High-performance liquid chromatographic procedures with ultraviolet detection were developed for the quantitative determination of sulfadiazine (SDA) and trimethoprim (TMP) in swine tissues (kidney, liver, muscle, fat and fat + skin). In addition, high-performance liquid chromatography with atmospheric pressure chemical ionization mass spectrometry was used for the confirmation of the identity ...

We identified a signaling pathway that prevents initiation of sporulation in Bacillus subtilis when replication initiation is impaired. We isolated mutations that allow a replication initiation mutant (dnaA) to sporulate. These mutations affect a small open reading frame, sda, that was overexpressed in replication initiation mutants and appears to be directly regulated by DnaA. Mutations in rep...
