Effects of CO2 elevation on the responses to flooding in black spruce (P. mariana) and tamarack (L. larcina) seedlings
(2016)Anthropogenic activities have been increasing the atmospheric CO2 concentration globally and the increase is predicted to continue to rise in the future. Increased CO2 has been shown to increase photosynthetic rates as ... -
The effects of copper, calcium, and nickel on the olfactory response of fathead minnows: from neurophysiology to behaviour
(2014-01-22)The olfactory system is essential for a fish to be successful in an ecological context, and has been demonstrated to be sensitive to a variety of toxicants. The current biotic ligand model (BLM) for copper is an acute-toxicity ... -
The effects of exogenous and endogenous gonadal hormones and hormonal sensitivity on eating disorder symptoms
(2012-11-10)A previous study found that a history of oral contraceptive (OC) side effects was associated with greater body dissatisfaction and eating dysfunction (Bird & Oinonen, 2011). This finding contributes to the growing body of ... -
Effects of feed and operating conditions on the performance and membrane fouling of a submerged anaerobic membrane bioreactor
(2012)Anaerobic membrane bioreactors (AnMBRs) have been recognized as an effective method for enhanced wastewater treatment and re-use. However, the loss of the membrane performances due to membrane fouling remains a major ... -
Effects of freezing on UV inactivation of waterbourne microorganisms
(2009)In northern communities where source water may be frozen for parts of the year or wastewater is treated using freezing technology, the efficiency of UV inactivation may be affected. This research was carried out to investigate ... -
Effects of gratitude and cognitive load on delay discounting: replication failures in two experiments
(2023)Delay discounting is the phenomenon whereby the value of future rewards is discounted as a function of time. Individual differences in discounting rate have been linked to a range of correlates and research has suggested ... -
The effects of I/Q imbalance and improper Gaussian noise on different wireless communication systems
(2020)The next-generation of wireless networks is required to support a myriad of new demands, including higher data rate, lower latency, greater system capacity, massive connectivity, as well as increased power efficiency. ... -
The effects of invasive dreissenid mussels on the offshore food web of Lake Simcoe, Ontario
(2019)Dreissenid mussels have successfully invaded North America, including the Great Lakes and their surrounding waterbodies. With their establishment, there have been many notable impacts including the rerouting of energy flow ... -
Effects of journaling: a study on the benefits of journaling in Chinese adolescents with anxiety
(2021)Academic performance plays a strong role in how Chinese students perceive their success throughout their adolescent years. As a result, this group of young people are left vulnerable to developing anxiety-related issues ... -
Effects of kettlebell mass & swing cadence on heart rate, blood lactate and ratings of perceived exertion during an interval kettlebell swing protocol
(2013)The purpose of this study was to determine the effects of kettlebell mass and swing cadence on heart rate, blood lactate and RPE during an interval kettlebell swing protocol in experienced female kettlebell users. Eighteen ... -
The effects of knee bracing on reactive agility performance among healthy soccer players – a pilot study
(2023)Soccer is the most popular sport in the world. The increase in the sport’s popularity is paralleled with an increased prevalence of knee injuries. Knee braces are commonly worn in athletic populations to prevent knee ... -
Effects of KNO3 and NaH2PO4 on lipid synthesis and CaCO3 accumulation in pleurochrysis carterae and newly identified algal shell coccolith structure
(2019)Due to the limited energy reserves and the increasing demand for energy, a large number of greenhouse gases such as CO2 have been released to the air. Therefore, there is an urgent need to find new sources of energy and ... -
Effects of macrophyte cutting on a whole lake ecosystem
(2023)Macrophytes are of significant importance to aquatic ecosystems, generating primary production in nearshore environments and providing physical structure and habitat for organisms in the littoral zone of lakes. Macrophyte ... -
The effects of moderate exercise on cognitive, cervical, and vestibulo-ocular functioning in healthy individuals: a pilot study
(2018)While cognitive and physical rest have long been the protocol that most physicians have recommended for concussions, there has been an increase in interest with regards to the prescription of low intensity symptom-limited ... -
The effects of naturally-derived plant compounds on pseudomonas aeruginosa pathogenicity
(2014-12-12)Pseudomonas aeruginosa has risen as one of the most resistant bacterial pathogens affecting people worldwide. Inefficacy of current antimicrobial treatments to relieve P. aeruginosa infections demands the need for novel ... -
The effects of neurocognitive and physical tasks on breathing and executive functioning in healthy versus concussed Canadian military members
(2022)When on active-duty, Canadian Armed Forces (CAF) members may be exposed to dangers and repetitive sub-concussive impacts such as explosive devices, loud gunfire, and handto-hand physical combat. These individuals are at ... -
Effects of nitrogen supply on the physiological and morphological responses to elevated [CO2] in yellow birch (Betula alleghaniensis Britt.)
