At a global scale, Canada is the second largest cranberry producer, with Quebec being producing region within Canada. Efficient water use in agricultural production has long been topic of outmost importance to producers, and governing bodies. The immediacy climate change effects sped up need find solutions that conserve water. One such promising technology irrigation using real-time tensiometer...

The purpose of this study was to verify the effect of testosterone depletion on healing of surgical skin wounds at different ages and post-operative periods. Forty-four Wistar male rats were divided into four groups: Group 1Y (n = 11) - young control, sham-operated rats (30-day old); Group 1A (n = 10) - adult control, sham-operated rats (3 to 4-month old); Group 2Y (n = 10) - young rats after b...

Cut-flower production of Rosa hybrida ‘Kardinal’ and ‘Fire and Ice’ were compared between two canopy management regimes: shoot-bending and hedgerow without shootbending, and between hydroponics and non-hydroponic (UC Mix) culture with a tensiometer-based irrigation system. We observed the number and length of all harvestable flowering shoots from September 1997 to August 1999 in order to assess...

Roots of hydroponically grown maize (Zea mays cv LG11) have a greatly reduced growth rate at 5 degrees C (0.02 millimeters per hour) compared with those at 20 degrees C (1.2 millimeters per hour). Various physical parameters of roots growing at each temperature were compared. Turgor pressure of cells in the elongation zone increased from 0.59 +/- 0.05 megapascal at 20 degrees C to 0.82 +/- 0.04...

BACKGROUND Many studies have reported the increase in strength of the untrained contralateral limb after unilateral training. The aim of this study was to compare the cross education effect in the young and elderly persons. METHODS In this quasi-experimental and pre-post study, 12 young people aged 28.25 ±3.11 years and 12 elderly persons (aged 73.08 ± 5.3 years) participated. The subjects ha...

BACKGROUND Photochemical tissue bonding (PTB) is a promising sutureless technique for tissue repair. PTB is often achieved by applying a solution of rose bengal (RB) between two tissue edges, which are irradiated by a green laser to crosslink collagen fibers with minimal heat production. In this study, RB has been incorporated in chitosan films to create a novel tissue adhesive that is laser-ac...

The aim of this study was to compare the mechanical properties of autologous rectus fascia (ARF), two groups of commercially available cadaveric fascia lata commonly used in pubovaginal sling surgery [freeze-dried (FD) and solvent-dehydrated (SD)], and commercially available cadaveric dermal grafts (DG) evaluate differences in tissue strength and stiffness. We prospectively studied the maximum ...

We developed a novel technique enabling determination of the permeability of electrospun yarns composed of hundreds of fibers. Analyzing the wicking kinetics in a yarn-in-a-tube composite conduit, it was found that the kinetic is very specific. The liquid was pulled by the capillary pressure associated with the meniscus in the tube while the main resistance comes from the yarn. Therefore, one c...

[Purpose] The aim of this technical note was to report significant differences in the tension forces of the different-sized Thera-band(®) elastic bands (Hygenic Corp.) determined by us versus the manufacturer. [Subjects] Two trained observers performed all measurements. [Methods] The tension force (kilogram-force units) of eight color-coded elastic bands (tan, yellow, red, green, blue, black, s...

The vascular anastomosis free of suture was made by using an absorbable suture and its tensile strength was compared with that of non-absorbable suture anastomosis. 29 adult mongrel dogs weighing 7.5 to 13.5 kg were used. Two kinds of vascular anastomosis were performed, that is, artery-to-artery anastomosis and vascular prosthetic graft to artery anastomosis. They were made in the right caroti...
