Development of Chitosan Green Composites Reinforced with Hemp Fibers: Study of Mechanical and Barrier Properties for Packaging Application.

The use of bioresourced packaging materials is an interesting solution for ecological issues. This work aimed to develop novel chitosan-based packaging materials reinforced with hemp fibers (HF). For this purpose, chitosan (CH) films were filled with 15%, 30%, and 50% (/) of two kinds of HF: Untreated fibers cut to 1 mm (UHF) and steam exploded fibers (SEHF).

Study and optimization of oil-in-water emulsions formulated by low- and high-frequency ultrasounds.

Objective: A combined treatment using both low-frequency (20 kHz) and high-frequency ultrasounds (1.63 MHz) is a promising new process to stabilize emulsions with minimalist formulation. In order to optimize process parameters, a Doehlert experimental design was performed with oil-in-water emulsions, presently used for cosmetic products, composed of water, caprylic/capric triglycerides and oleic acid.

Review of High-Frequency Ultrasounds Emulsification Methods and Oil/Water Interfacial Organization in Absence of any Kind of Stabilizer.

Emulsions are multiphasic systems composed of at least two immiscible phases. Emulsion formulation can be made by numerous processes such as low-frequency ultrasounds, high-pressure homogenization, microfluidization, as well as membrane emulsification. These processes often need emulsifiers' presence to help formulate emulsions and to stabilize them over time.

Interest of Pickering Emulsions for Sustainable Micro/Nanocellulose in Food and Cosmetic Applications.

In the present review, natural and non-toxic particles made of micro/nanocellulose were specifically targeted as stabilizers of emulsions located at dispersed and continuous phases interfaces (called Pickering Emulsions, PEs). PEs are biphasic systems stabilized by solid particles with a recent interest in food and cosmetic domains. PEs have been more and more studied in the last ten years due to their advantages compared to conventional emulsions with surfactants.

Genetic rescue increases fitness and aids rapid recovery of an endangered marsupial population.

Genetic rescue has now been attempted in several threatened species, but the contribution of genetics per se to any increase in population health can be hard to identify. Rescue is expected to be particularly useful when individuals are introduced into small isolated populations with low levels of genetic variation. Here we consider such a situation by documenting genetic rescue in the mountain pygmy possum, Burramys parvus.

Health visitors have much to offer pre-registration child branch student nurses.

The primary care workforce has recently become the focus of several reports, which highlight the preparation and upskilling of nurses for a move to acute care in the community and plans to widen the community and primary care workforce. This paper explores current health plans in relation to pre-registration nurse education and identifies the health visitor as having key qualities and skills to manage child branch student nurses' community placements. A health visitor's perspective reinforces the discussion and highlights how the current climate offers a valuable opportunity for health visitors to promote a positive learning environment.

Pelvic floor muscle training with biofeedback and bladder training in elderly women: a feasibility study.

Objective: It is generally assumed that interventions used to treat urinary incontinence (UI) in young women could simply be applied to older competent and motivated women, but these assumptions have not been formally tested. The purpose of this study was to determine the feasibility of using physical therapies to treat UI in older women.

Design: Twelve-week time series.
