The recently proposed random-phase-free method enables holographic reconstructions with very low noise,which allows fine projections without time integration of sub-holograms. Here, we describe the additional advantage of this method, namely, the extended depth of sharp imaging. It can be attributed to a lower effective aperture of the hologram section forming a given image point at the projection screen. We experimentally compare the depth of focus and imaging resolution for various defocusing parameters in the cases of the random-phase method and the random-phase-free method. Moreover, we discuss the influence of the effective aperture in the presence of local obstacles in the hologram＇s plane.

Purpose: This study aims to identify the concussion-related training and education needs of Gaelic Athletic Association(GAA) coaches in Ireland,as well as the preferred method of concussion education ***: We used a self-report questionnaire to collect data from a convenience sample of 108 GAA coaches in Ireland. Data were captured on(1) informational needs and desires,(2) preferred methods of delivery, and(3) concussion practices and procedures. Questionnaires were completed electronically from June 3 rd–September 29 th, ***: Coaches indicated that they were most interested in receiving information about the(1) signs and symptoms of concussion,(2) assessment of concussion, and(3) return-to-play guidelines. Over two-thirds of participants indicated that in-person training would be the most effective mode of delivery of concussion education for this population. Additionally, only 10% coaches reported that before the start of the season they talked to their athletes about concussion management and safety, and this was more common among coaches who reported being formally educated about ***: Our findings reveal a disconnect between the concussion education needs and the education that is currently provided to GAA coaches, in terms of content and delivery modality. Our results suggest a need for a multifaceted approach to concussion education, tailored to the needs and learning preferences of the target population.

The study deals with adsorption of Naphthol Green B on two unburned carbons and the parent coal,from which the UCs have been created in a fluidised-bed power *** attention has been paid to the adsorption equilibrium modelling:experimental data has been analysed using 2-parameter(Langmuir,Freundlich) and3-parameter(Redlich-Peterson) isotherms — both linear and non-linear regressions have been used for the estimation of the isotherm *** the case of both UCs,the Langmuir isotherm model provides the worst fit,whereas 2-parameter Freundlich and 3-parameter Redlich-Peterson models are both good,from which 3-parameter Redlich-Peterson isotherm provides slightly better results(despite the penalty used for the higher number of parameters).In the case of both UCs,the linear regression of Freundlich and Redlich-Peterson models provides good results(comparable with non-linear regressions).Unlike both UCs,the best fit of the experimental data from the adsorption on the coal has been achieved by the Langmuir isotherm *** results based on the Freundlich or Redlich-Peterson model were(in this case) somewhat worse.

Non-thermal plasma (NTP) technology offers wide potential use in the food technology, the same as in the unconventional agriculture. Some seeds, dry fruits, grains and their sprouts gain popularity in the culinary industry as 'raw seeds'. This review paper draws the current research and trends in NTP pre-treatment of selected seeds/fruits that are useable as 'raw seeds'. The main applications are connected with activation of seed germination, early growth of seedlings, microbial inactivation of seed/fruit surface, and possibility of increasing quantity of biological active compounds in sprouting seeds. The paper presents a list of plant species that are able to be used as 'raw seed' including current information about main type of NTP treatment implemented.

Glutathione contents and activity ofglutathione-dependent enzymes in the body of insects inhabiting polluted areas depend on toxin kind, concentration and exposure time. Enzymatic response may be modified by gender, age, developmental stage and state of nutrition. Also, chronic exposure to metals in the environment may cause the selection of individuals resistant to some environmental toxins. To assess the degree of adaptation of Chorthippus brunneus to metal-polluted habitats, we measured glutathione contents and the activity of selected glutathione-dependent enzymes in the offspring of aging mothers which differed in time and intensity of exposure to metals in their habitats. We tested whether differences represent temporal shifts in tolerance range or were genetically preserved and inherited by future generations. We investigated insects from three populations. Two live in heavily metal-burdened areas, exposed to metals for 170 （Szopienice） or 50 years （Olkusz） and the third inhabits an unpolluted reference site （Pilica）. The most important findings were age-by-site interactions for all biochemical analyses. Nymphs from Szopienice had lower glutathione contents and lower glutathione-dependent enzyme activity in comparison with nymphs from the reference site. This was especially distinct in nymphs hatched from eggs laid by young females. The offspring of aging females from Olkusz, in terms of glutathione contents and glutathione reductase activities, revealed similar patterns to those from the reference site. For the remaining parameters, enzyme activity patterns in nymphs from Olkusz were similar to those of nymphs from Szopienice.
