The residual agricultural plastic film in China is not easily recovered due to the thinness and poor mechanical properties of domestic films, a large amount remaining farmland soil poses great threat quality crop production. A spring-tooth collector (SRPFC) widely used (RPF) recycling operations. However, there are two major problems current SRPFC: low recovery rate (RRRF) caused by difficulty ...

We investigate the role of ram pressure stripping in the Virgo cluster using N-body simulations. Radial orbits within the Virgo cluster's gravitational potential are modeled and analyzed with respect to ram pressure stripping. The N-body model consists of 10 000 gas cloud complexes which can have inelastic collisions. Ram pressure is modeled as an additional acceleration on the clouds located a...

A novel stripping chemiluminescence (CL) method in situ has been developed which is a combination of selective stripping and CL detection in situ. This method consists of a concentration (pre-electrolysis) step, in which the analyte metal ion is reduced at a controlled potential whilst being deposited as the metal on a solid electrode placed in an electrogenerated chemiluminescence flow cell, a...

The aim of this study was to compare the results of high ligation and stripping of the great saphenous vein (GSV) trunk combined with foam sclerotherapy with conventional surgery for the treatment of superficial venous varicosities of the lower extremity. One hundred and thirty eight patients with primary or secondary superficial venous varicosities of the lower extremity were included. 60 unde...

INTRODUCTION The aim of this study was to evaluate the prevalence of bacteremia associated with an orthodontic stripping procedure. METHODS The study included 29 orthodontic patients (mean age, 18.2 ± 3.4 years). We used a standardized stripping procedure: a perforated stripping disk with a contra-angle hand piece was used at a low speed (<15,000 rpm; 10 seconds) on the mandibular anterior te...

a novel and selective method for the fast determination of trace amounts of zn(ii)ions in water samples has been developed.  the first additional carbonyl and carboxyl functionalized-nano graphene (spfnano graphene). the presence of additional carbonyl and carboxyl groups located at the edge of the sheets makes go sheets strongly hydrophilic, allowing them to readily swell and disperse in water...

A single-phase (Ni,Pt)Al coating was removed by soft chemical stripping method successfully after preceding oxidation at 1100 °C for 300 h, and a fresh one refurbished subsequently. Oxidation behaviour of the studied in comparison with virgin °C. The results show that exhibited superior isothermal cyclic resistance than terms rate surface rumpling. effects roughness residual elements on rate, r...

The oesophageal vestibule lies at the lower end of the oesophagus immediately above the stomach. Pressure recordings in normal adults indicate that after pharyngeal deglutition the vestibule relaxes. They show that this relaxation occurs shortly after deglutition and that it persists until the oeso-phageal stripping wave reaches the vestibule (Fyke, Code, and Schlegel, 1956). Carrd and Astley (...
