This paper discusses the methodology and performance records of photo-interpretation studies applied to hydrogeological investigations carried out mainly in the Prairie provinces of Western Canada. Most of these studies involved the search for previously unknown commercial sources of groundwater in southern Saskatchewan and Alberta.Performance records reported cover the 13-year period from 1956 to 1969. During this period, 203 requests were made for consulting assistance. Approximately 90% of these requests resulted in the interpretation of hydrogeological environments displayed on conventional black-and-white aerial photography. Follow-up field data are available on 127 projects, which include 84 groundwater development investigations that we supervised fully from initial photo-interpretation studies to production-well installation, pump testing, data analysis, and evaluation of safe yield.Airphoto interpretation techniques proved helpful in correctly identifying commercial sources of groundwater in approximately 7 out of 10 projects. About half of the water sources were required for urban use and about one-quarter were required for a variety of industrial uses. Also, roughly half of the studies involved finding 10 to 60 Imperial gallons a minute (45.5 to 272.8 l/min) and roughly half involved finding 60 to 2000 Imperial gallons a minute (272.8 to 9092 l/min). Less frequently, the groundwater studies dealt with regional mapping of the surficial and bedrock hydrogeology, with setting up monitoring systems for the detection and surveillance of groundwater contamination, and with locating small groundwater supplies.

This research is a form of analysis and evaluation of the menu at the Bintan Inti Executive Village (BIEV) Clubhouse through a menu engineering system with the aim of improving the quality and effectiveness of the menu served. The formulation of the problem which is the basis of this research is how to improve the quality of the food and beverage menu through the menu engineering system and what recommendation actions should be taken based on the resulting data from the analysis that appears. This study uses variables, which are menu analysis in improving the quality of the menu at BIEV Clubhouse with sub variables, such as food cost, menu mix, and contribution margin. The results of this study that there were 8 menus or 30.77% menus with star categories, 5 menus or 19.23% menus with the plowhorse category, 4 menus or 15.38% menus with the puzzle category, and 9 menus or 34.62%. menu with dog category. The recommended follow-up actions to BIEV Clubhouse management is reducing the menu with the dog category, evaluating product prices and production costs for menus with the plowhorse category, taking suggestive selling steps for menus with the puzzle category, and maintaining the quality and performance of menus with the star category.

Abstract Background Flow diverters (FDs) are widely used in the treatment of intracranial aneurysms, but the required medication increases the risk of haemorrhagic complications and limits their use in the acute setting. Surface modified FDs may limit the need for dual antiplatelet therapy (DAPT). Hydrophilic polymer coating (HPC) may reduce the need of medication. Methods This explorative study, approved by the local authorities and the local welfare committee, compared stent behaviour and overall tissue response between HPC-coated FDs and uncoated FDs, both implanted into the common carotid arteries of eight New Zealand white rabbits. Endothelialisation, inflammatory response, and performance during implantation were assessed. Angiographic follow-up was performed to observe the patency of the devices after implantation and after 30 days. Histological examinations were performed at 30 days to assess foreign body reaction and endothelialisation. Kruskal-Wallis and Wilcoxon tests were used to compare non-parametric variables. Results Angiography showed that both coated and uncoated FDs performed well during implantation. All devices remained patent during immediate follow-up and after 30 days. Histopathology showed no significant difference in inflammation within the vessel wall between the two cohorts (2.12 ± 0.75 vs. 1.96 ± 0.79, p = 0.7072). Complete endothelialisation of the stent struts was seen with very similar (0.04 ± 0.02 mm vs. 0.04 ± 0.03 mm, p = 0.892) neoendothelial thickness between the two cohorts after 30 days. Conclusion Taking into account the limitation in sample size, non-significant differences between the HPC-coated and uncoated FDs regarding implantation, foreign body response, and endothelialisation were found.

Abstract Objectives: In the neuroHIV literature, cognitive reserve has most often been operationalized using education, occupation, and IQ. The effects of other cognitively stimulating activities that might be more amenable to interventions have been little studied. The purpose of this study was to develop an index of cognitive reserve in people with HIV, combining multiple indicators of cognitively stimulating lifetime experiences into a single value. Methods: The data set was obtained from a Canadian longitudinal study (N = 856). Potential indicators of cognitive reserve captured at the study entry included education, occupation, engagement in six cognitively stimulating activities, number of languages spoken, and social resources. Cognitive performance was measured using a computerized test battery. A cognitive reserve index was formulated using logistic regression weights. For the evidence on concurrent and predictive validity of the index, the measures of cognition and self-reported everyday functioning were each regressed on the index scores at study entry and at the last follow-up [mean duration: 25.9 months (SD 7.2)], respectively. Corresponding regression coefficients and 95% confidence intervals (CIs) were computed. Results: Professional sports [odds ratio (OR): 2.9; 95% CI 0.59–14.7], visual and performance arts (any level of engagement), professional/amateur music, complex video gaming and competitive games, and travel outside North America were associated with higher cognitive functioning. The effects of cognitive reserve on the outcomes at the last follow-up visit were closely similar to those at study entry. Conclusion: This work contributes evidence toward the relative benefit of engaging in specific cognitively stimulating life experiences in HIV.

Abstract Objective To evaluate whether performing preoperative urodynamic study influences postoperative urinary symptoms of women with stress urinary incontinence that underwent transobturator sling. Methods Retrospective analysis of patients treated for stress urinary incontinence by transobturator sling from August 2011 to October 2018. Predictor variables included preoperative urodynamic study, age, incontinence severity, body mass index, preoperative storage symptoms and previous anti-urinary incontinence procedure. Outcome variables were postoperative subjective continence status, storage symptoms and complications. Logistic regression after propensity score was employed to compare outcomes between patients who underwent or not pre-operative urodynamic study. Results The present study included 88 patients with an average follow-up of 269 days. Most patients (n = 52; 59.1%) described storage symptoms other than stress urinary incontinence, and 38 patients (43.2%) underwent preoperative urodynamic studies. Logistic regression after propensity score did not reveal an association between urinary continence outcomes and performance of preoperative urodynamic study (odds ratio 0.57; confidence interval [CI]: 0.11–2.49). Among women that did not undergo urodynamic study, there was a subjective improvement in urinary incontinence in 92% of the cases versus 87% in those that underwent urodynamic study (p = 0.461). Furthermore, postoperative storage symptoms were similar between women who did not undergo urodynamic study and those who underwent urodynamic study, 13.2% versus 18.4%, respectively (p = 0.753). Conclusion Preoperative urodynamic study had no impact on urinary incontinence cure outcomes as well as on urinary storage symptoms after the transobturator sling in women with stress urinary incontinence.

Abstract Background The 2014 hypertension guideline raised treatment goals in older adults. The study objective was to examine changes in blood pressure (BP) control (<140/90 mmHg) from 2011-2013 to 2016-2017 among Black and white older adults with treated hypertension. Methods Participants were 1600 white and 650 Black adults aged 71-90 years in the Atherosclerosis Risk in Communities (ARIC) Study with treated hypertension in 2011-2013 (baseline) who had BP measured in 2016-2017 (follow up). Factors associated with changes in BP control were examined by race. Results BP was controlled among 75.3% of white and 65.7% of Black participants at baseline and 59.0% of white and 56.5% of Black participants at follow up. Among those with controlled BP at baseline, risk factors for incident uncontrolled BP included age (RR 1.15 per 5 years, 95% CI 1.07-1.25), female sex (RR 1.36, 95% CI 1.16-1.60), and chronic kidney disease (CKD) (RR 1.19, 95% CI 1.01-1.40) among white participants, and hypertension duration (RR 1.14 per 5 years, 95% CI 1.03-1.27) and diabetes (RR 1.48, 95% CI 1.15-1.91) among Black participants. Among those with uncontrolled BP at baseline, white females vs males (RR 0.60, 95% CI 0.46-0.78) and Black participants with CKD vs without (RR 0.58, 95% CI 0.36-0.93) were less likely to have incident controlled BP. Conclusions BP control decreased among white and Black older adults. Black individuals with diabetes or CKD were less likely to have controlled BP at follow up. Higher treatment goals may have contributed to these findings and unintended differences by race.

Mental practice (MP) in music refers to the ability to rehearse music in the mind without any muscular movements or acoustic feedback. While previous studies have shown effects of the combination of MP and physical practice (PP) on instrumental performance, here we aimed to assess MP and PP effects on memory abilities. During a 1-week music practice protocol, classical guitarists were asked to practise a new musical piece using either a combination of MP and PP or PP alone. We asked participants to perform the piece and notate it at 3 different times: Day 1 and Day 7 of the 1-week practice protocol and 10 days after its completion (follow-up session). Results showed that the combination of MP and PP improves both notation and performance tasks compared with PP alone. Furthermore, we observed a clearer difference in memory performance in the follow-up session as compared with that in Day 7. Our results show that musicians can use both MP and PP to improve long-term retention and to reduce physical workload and playing-related overuse injuries. Therefore, we encourage music educators to teach MP in the classrooms rather than letting students discover it in a serendipitous way.

Background: Improperly fitted shoes are frequently seen in athletes participating in Special Olympics competitions. This foot-to-shoe mismatch may result in deformities as well as discomfort and reduced performance or injuries in competitions. A primary purpose for providing medical screenings is to identify conditions unknown and to promptly refer to an appropriate provider for evaluation and care. This study attempts to determine the prevalence of improperly fitted shoes and the rate of referral for Special Olympics athletes screened at Fit Feet venues. Methods: To evaluate the foot-to-shoe mismatch and rate of referral, 4,094 Fit Feet screenings of Special Olympics athletes participating in US competitions in 2005 to 2009 were analyzed. The participants were 58.5% male and 41.5% female, with a median age of 25.6 years. A power analysis and the χ2 test were used. The athletes voluntarily underwent a foot screening that followed the standardized Special Olympics Fit Feet protocol. The Brannock Device for measuring feet was used to assess proper fit. Results: A proper fit was found in 58.56% of the athletes, with 28.60% wearing shoes too big and 12.84% wearing shoes too small. Unrelated to shoe fit, 20% of the athletes required referrals for professional follow-up based on abnormal clinical findings. Conclusions: There is a significant (41.44%) mismatch of foot to shoe in Special Olympics athletes. The most common mismatch is a shoe too big, with a much smaller number of athletes having shoes too small. Awareness of this foot-to-shoe incompatibility may be useful for the development of shoes better designed for athletes with a foot structure not consistent with conventional shoes. Because 20% of the athletes required a referral for professional follow-up, Fit Feet examinations are important for identifying athletes with conditions that can be more readily evaluated and treated, thus improving the athletes’ comfort and performance. Beyond knowing the rate of referral, future studies can determine the conditions or findings that necessitate a referral and the ultimate outcome of that referral.
