Systemic anaphylaxis following centipede envenomation: A case report and review of literature.

Centipede envenomation is usually not life-threatening. They usually present with local symptoms of swelling and pain. Centipede venoms contain large amounts of allergenic proteins that can pose a risk of allergic complications following the bite.

Forecasting the Problem of Excessive Oil Entrainment in a Desalter Using Spinning Drop Method.

Frequent desalter upsets in the refineries processing opportunity crude oils are often triggered by a rapid and uncontrollable buildup of the rag layer, a thick water-in-oil emulsion, at the oil-brine interface. This is caused by spontaneous emulsification of brine in oil. This study investigates a unique observation from a spinning drop (SD) tensiometer, revealing the low apparent interfacial tension and rigidity of SD caused by spontaneous emulsification.

Orthodontic Treatment of a Case With Palatally Impacted Canine and Missing Molars: A Case Report.

Interdisciplinary care provides a comprehensive method for the management of impacted teeth. Careful planning is necessary to achieve the desired treatment goals. This article highlights the importance of diagnosis as well as adequate treatment planning for the eruption of impacted teeth and the management of missing molars to achieve a balanced occlusion in circumstances when an ideal occlusion cannot be achieved.

Comparison between drill and drill free screws as a source of rigid orthodontic anchorage: a prospective clinical study.

Objective: The study was undertaken to evaluate and compare the stability and surrounding soft tissue reaction of the Drill and Drill-free miniscrews when used as anchorage unit for en-masse retraction of maxillary anteriors.

Methods: 20 patients were selected. Of the total 20 Drill and drill free screws, halfscrews were placed on the right side and half on the left side of maxilla and clinical evaluation for mobility and any surrounding soft tissue inflammation was done.

A comparitive clinical study between self tapping and drill free screws as a source of rigid orthodontic anchorage.

Background And Objectives: Self-tapping miniscrews are commonly being used as a temporary anchorage device for orthodontic purpose. A prerequisite for the insertion of these screws is the preparation of a pilot hole, which is time consuming and may result in damage to nerves, tooth root, drill bit breakage and thermal necrosis of bone. On the other hand the design of drill-free screws enables them to be inserted without drilling.

Evaluation of demineralization adjacent to orthodontic bracket and bond strength using fluoride-releasing and conventional bonding agents.

Background And Objectives: One of the most difficult problems encountered in orthodontic treatment with fixed appliance is the control of enamel demineralization around the brackets. Fluoride-releasing bonding adhesives were introduced to aid in the prevention of demineralization adjacent to orthodontic brackets. Hence, an in vitro study was conducted to evaluate and compare demineralization adjacent to the orthodontic bracket and the bond strength using fluoride-releasing adhesive and conventional adhesive.

The ideal smile and its orthodontic implications.

Aim: To determine the parameters for an ideal smile.

Methods: Ten laypersons classified frontal photographs of 62 smiling individuals between 18 and 25 years of age into five categories: 1, poor; 2, fair; 3, good; 4, very good; and 5, excellent. The scores obtained for each smile were averaged.

A clinical evaluation of orthodontic mini-implants as intraoral anchorage for the intrusion of maxillary anterior teeth.

Aim: To determine the efficacy of mini-implants as intraoral anchorage during en masse intrusion of the six maxillary anterior teeth.

Methods: Ten patients from the Department of Orthodontics, KLE University, Belgaum, India, who required intrusion of their anterior teeth were selected for this study. After initial alignment and leveling, the maxillary arch was divided into one anterior segment and two posterior segments.

Evaluation of Moyers mixed dentition analysis in school children.

Background And Objective: The purpose of this study is to test the reliability of Moyers mixed dentition analysis in school children.

Materials And Methods: A study was conducted on a sample of 150 school children within the age group of 13 to 16 years old who had all permanent teeth that were fully erupted. Dental impressions were taken with alginate impression material and immediately poured with dental stone.

Catastrophic drop breakup in electric field.

We report novel observations revealing the catastrophic breakup of water drops containing surfactant molecules, which are suspended in oil and subjected to an electric field of strength approximately 10(5) V/m. The observed breakup was distinctly different from the gradual end pinch-off or tip-streaming modes reported earlier in the literature. There was no observable characteristic deformation of the drop prior to breakup.

"Micro-pottery"--marangoni effect driven assembly of amphiphilic fibers.

We report spontaneous supra-assembly of fibrous surfactant crystallites at the air-solution interface resulting in spectacular arrays of two-dimensional spiral and three-dimensional "micro-pottery"-like superstructures. Surface pressure differential driven bending of the embryonic fiber nuclei and Marangoni convection driven fiber migration/alignment appear to be the causal factors behind this phenomenon. The assemblies form at specific crystal-growth velocities dictated by the relative time scales for fiber bending/alignment and their rigidification/immobilization as they grow.
