Comparative study of initial stages of copper immersion deposition on bulk and porous silicon

2013

Initial stages of Cu immersion deposition in the presence of hydrofluoric acid on bulk and porous silicon were studied. Cu was found to deposit both on bulk and porous silicon as a layer of nanoparticles which grew according to the Volmer-Weber mechanism. It was revealed that at the initial stages of immersion deposition, Cu nanoparticles consisted of crystals with a maximum size of 10 nm and inherited the orientation of the original silicon substrate. Deposited Cu nanoparticles were found to be partially oxidized to Cu2O while CuO was not detected for all samples. In contrast to porous silicon, the crystal orientation of the original silicon substrate significantly affected the sizes, dens…

Effect of water immersion on post-rotatory and caloric nystagmus.

1991

Caloric nystagmus and post-rotatory nystagmus were recorded with and without head-out water immersion. As water immersion reduces body weight by about 90% owing to buoyancy, it decreases somatosensory inputs. Thus water immersion can be used to simulate a weightless environment. Caloric nystagmus was enhanced significantly by water immersion; however, post-rotatory nystagmus was not. These findings demonstrate that caloric nystagmus is easily affected by water immersion which decreases somatosensory inputs, but that post-rotatory nystagmus is not.

The Effect of 16-Minute Thermal Stress and 2-Minute Cold Water Immersion on the Physiological Parameters of Young Sedentary Men

2020

This study aimed to determine the effect of 16 minutes of thermal stress followed by 2 minutes of cold water immersion on the physiological parameters of fifty-five sedentary men (mean age 20.15±1.30 years), who were exposed to 16 minutes of sauna (temperature: 90-91℃; relative humidity: 14-16%) followed by 2 minutes of cold water immersion (12℃). The participants' somatic characteristics were determined before entering the sauna, and their body mass and blood pressure were measured before and after sauna treatment. Physiological parameters were monitored during the 16-minute sauna session and the 2-minute cold water immersion (CRIO) or shower. The subjects perspired 0.21-0.27 litres during…

In Vitro Regeneration of

2019

Three caper (Capparis spinosa L.) biotypes grown on the Sicilian island of Salina (38°33′49″ N) were micropropagated to evaluate two different in vitro culture systems: one using the traditional solid medium, and the other based on liquid culture in a PlantForm bioreactor. PlantForm is a temporary immersion system (TIS), a new propagation method in which the shoots undergo temporary immersion in a liquid medium in order to avoid the accumulation of gas through forced ventilation. This study proposes a protocol to improve the efficiency of in vitro propagation of caper plants, while also reducing production costs, because of the elimination of the gelling agent, and manual labor, requiring l…

New migration processes and new frontiers for linguistic research

2021

Recent migrations show unprecedented characteristics in terms of migratory routes, individual profiles of migrants and condition of isolation in arrival contexts. Combining sociolinguistic and linguistic perspectives, the article reconstructs the forms of linguistic contact between local and migrant populations in one of the main gateways to Europe, Palermo (Italy), and the specific conditions of local language acquisition by newcomers. It is argued that notions of (im)mobility and segregation must be included in migration-centred linguistic research

Water immersion methods do not alter muscle damage and inflammation biomarkers after high-intensity sprinting and jumping exercise

2020

Purpose The aim of this study was to compare the efficacy of three water immersion interventions performed after active recovery compared to active recovery only on the resolution of inflammation and markers of muscle damage post-exercise. Methods Nine physically active men (n = 9; age 20‒35 years) performed an intensive loading protocol, including maximal jumps and sprinting on four occasions. After each trial, one of three recovery interventions (10 min duration) was used in a random order: cold-water immersion (CWI, 10 °C), thermoneutral water immersion (TWI, 24 °C), contrast water therapy (CWT, alternately 10 °C and 38 °C). All of these methods were performed after an active recovery (1…

Early Immersion in Minority Language Contexts: Canada and Finland

2020

This chapter discusses early immersion in a minority language in two bilingual countries, Canada and Finland. In Canada, immersion in the minority language, French, has been implemented since the mid-1960s and Finland introduced immersion in Swedish in the mid-1980s. As the core features of immersion education evolve in tandem with second language education theorizing (particularly as it relates to the interdependence and hybridity between and within languages), so too does the need to revisit the relevance of these core features across different contexts. In this vein, this chapter compares how changing socio-political realities in the two contexts have influenced program development in re…

The Effects of Cold Water Immersion on the Recovery of Drop Jump Performance and Mechanics : A Pilot Study in Under-20 Soccer Players

2020

Cold water immersion (CWI) is a popular method used for enhancing recovery from exercise. However, the efficacy of this approach is inconclusive and studies investigating variables contributing to overall performance are scarce. Additionally, few studies have investigated the recovery of stretch-shortening cycle (SSC) performance after a fatiguing SSC task. The SSC occurs naturally in human locomotion and induces a recovery pattern different from isolated muscle contractions (e.g., pure eccentric exercise). Therefore, the main aim of this study was to investigate the effects of a single CWI on jumping performance and mechanics after exhaustive SSC exercise. On a sledge apparatus, 10 male un…
