Only for PCC mortar with CEM I sulfate-resistant types of cement was it possible to achieve the same strength parameters as at 21 °C, during 28 days of mortar curing, and at a lowered temperature. Starting from day seven of setting at both above-mentioned temperatures, a relation between the values of the flexural and compressive strength expressed as a quotient of these values, amounting to ca. 0.14-0.19, was found.Lipid-lowering therapies are essential for the primary and secondary prevention of atherosclerotic cardiovascular disease (ASCVD). The aim of this study is to identify discrepancies between cholesterol management guidelines and current practice with a focus on statin treatment in an underserved population based in a large single urban medical center. Among 1042 reviewed records, we identified 464 statin-eligible patients. Age was 61.0 ± 10.4 years and 53.9% were female. Most patients were black (47.2%), followed by Hispanic (45.7%) and white (5.0%). In total, 82.1% of patients were prescribed a statin. An appropriate statin was not prescribed in 32.4% of statin-eligible patients who qualified based only on a 10-year ASCVD risk of ≥7.5%. After adjustment for gender and health insurance status, appropriate statin treatment was independently associated with age >55 years (OR = 4.59 (95% CI 1.09-16.66), p = 0.026), hypertension (OR = 2.38 (95% CI 1.29-4.38), p = 0.005) and chronic kidney disease (OR = 3.95 (95% CI 1.42-14.30), p = 0.017). Factors independently associated with statin undertreatment were black race (OR = 0.42 (95% CI 0.23-0.77), p = 0.005) and statin-eligibility based solely on an elevated 10-year ASCVD risk (OR = 0.14 (95% CI 0.07-0.25), p less then 0.001). Hispanic patients were more likely to be on appropriate statin therapy when compared to black patients (86.8% vs. 77.2%). Statin underprescription is seen in approximately one out of five eligible patients and is independently associated with black race, younger age, fewer comorbidities and eligibility via 10-year ASCVD risk only. Hispanic patients are more likely to be on appropriate statin therapy compared to black patients.Previous literature has shown how associate engagement has positively impacted on productivity, job satisfaction, safety, retention, consumer sentiment, and financial performance in hospitals and healthcare systems. However, a lack of research showing the relationship between associate engagement and job satisfaction within the long-term care environment has existed. Our objective was to investigate characteristics within the long-term care environment that promote and detract from associate job satisfaction and extrapolate the best practices in maintaining job satisfaction and engagement. This systematic review queried CINAHL, PubMed (MEDLINE), and Academic Search Ultimate databases for peer-reviewed publications for facilitators and barriers commensurate with employee job satisfaction in long-term care facilities using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and the Kruse Protocols. The authors identified 11 facilitators for job satisfaction and 18 barriers to job satisfaction in the 60 selected articles. The top four facilitators were Supportive Leadership, Capable and Motivated Employees, Positive Organizational Values, and Social Support Mechanisms. The top four barriers were condescending management style, high job demands, lack of self-care, and lack of training with medically complex patients.  https://www.selleckchem.com/products/bismuth-subnitrate.html  The systematic review revealed the importance of maintaining satisfied employees in the long-term care workplace through am emphasis leadership and on the facilitators identified to best serve their associates and improve care for residents.In this paper, a detailed analysis of the influence of phase noise on the micro-electro-mechanical system (MEMS) disk resonator gyroscope (DRG) is presented. Firstly, a new time-varying phase noise model for the gyroscope is established, which explains how the drive loop circuit noise converts into phase noise. Different from previous works, the time-varying phase noise model in this paper is established in mechanical domain, which gain more physical insight into the origin of the phase noise in gyroscope. Furthermore, the impact of phase noise on DRG is derived, which shows how the phase noise affects angular velocity measurement. The analysis shows that, in MEMS DRG, the phase noise, together with other non-ideal factors such as direct excitation of secondary resonator, may cause a low frequency noise in the output of the gyroscope system and affect the bias stability of the gyroscope. Finally, numerical simulations and experiment tests are designed to prove the theories above.The true extent of the mental health implications of the COVID-19 pandemic are unclear, but early evidence suggests poorer mental health among those exposed to the pandemic. The Internet may have differential effects, by both connecting people with resources, or reinforce the constant checking of negative information. Moreover, locus of control becomes important in an uncontrollable pandemic. The current study aimed to examine whether exposure to COVID-19 would relate to greater symptoms of depression, anxiety and stress, and to examine the role of internet use and locus of control. Adults in the United States and five European countries (N = 1723) answered an online survey through the website Mturk. Results show elevated psychological symptoms among those who have become infected with COVID-19 or perceive themselves to be at high risk if infected. Experience using the Internet relates to fewer symptoms, but information seeking is associated with more symptoms. Internet social capital relates to fewer symptoms of depression. Having an external locus of control relates to greater symptoms. These findings suggest that public health officials need to focus on the mental health effects of the pandemic, and that internet use and locus of control could be targets to improve mental health in the population.Background This study analyzes the relationship between depression and anxiety levels and positive and negative affect, self-esteem, and perceived social support from family and friends in an early and middle adolescent sample. These are psychological variables that are often associated with the prediction of emotional disorders, especially depression. Methods Participants (N = 467) were a representative sample of this group of adolescents and were recruited from schools in the city of Concepción, Chile. Part of the sample (N = 177) was assessed three additional times-at one-, two-, and four-month intervals. Results Results showed a practical stability of all measures across the four intervals, with no significant differences between sexes. Anxiety and depression displayed a similar pattern of significant relationships with affectivity, self-esteem, and social support. Depression had a higher correlation coefficient (-0.47) with positive affect, and so did anxiety with negative affect (0.58). Conclusions Taking into account 23 initial scores on affectivity, self-esteem, and social support in predicting both depression and anxiety scores at one-month, two-month, and four-month intervals, positive affect was present in three regression analyses, predicting depression scores; negative affect was present in anxiety scores.
