Optimizing beet seed germination via dielectric barrier discharge plasma parameters.

This study explores the synergistic effects of gas composition and electric field modulation on beetroot seed germination using dielectric barrier discharge (DBD) plasma. The investigation initially focuses on the impact of air plasma exposure on germination parameters, varying both voltage and treatment duration. Subsequently, the study examines how different gas compositions (argon, nitrogen, oxygen, and carbon dioxide) affect germination outcomes under optimal air plasma conditions.

Impact of dielectric barrier discharge plasma and plasma-activated water on cotton seed germination and seedling growth.

Unfavorable environmental conditions during planting can reduce seed germination and hinder seedling growth. To address this issue, manufacturers are exploring innovative and cost-effective methods, such as cold plasma discharge. This simple, low-cost, and efficient physical technique induces significant biological responses in seeds and plants without the use of traditional, environmentally hazardous chemicals.

Hip sonography update. Quality-management, catastrophes - tips and tricks.

Aim: Hip sonography is today considered to be the diagnostic standard tool for developmental dysplasia of the hip (DDH) diagnosis. In Germany special commissions control the quality of the sonograms according to checklists to keep the standard high and to avoid over- and under - treatment. This paper lists tips and tricks to avoid typical mistakes according to these results.

Fracture of the alumina-bearing couple delta ceramic liner.

The fracture rate of third-generation ceramic liners is greatly reduced compared with first- and second-generation liners because of improvements in the design and manufacturing process. Fractures of the alumina-bearing couple are rare for the same reason.This article describes a case of a fracture of an alumina-bearing couple delta ceramic liner without trauma history that was treated with ceramic-on-polyethylene revision total hip arthroplasty.

Retrospective and consecutive analysis of the long-term outcomes of the SBG stem: a 15-year follow-up study.

Background: In 1991, 230 cementless total hip arthroplasties (THAs) with anatomical Stolzalpe-Buchner-Graf (SBG) stems were implanted in 230 patients at our hospital. Patients were examined retrospectively and consecutively 15 years after the operations.

Methods: In total, 118 patients were available for follow-up (average 12.
