Estimating Maximum Power from Wind Turbines with a Simple Newtonian Approach

Published: August 2023

Action mechanics showing torques result from rates of variation in impulsive action motivated a new method to estimate maximum power from wind turbines. Newton’s third law of equality of action and reaction provides a strictly causal mechanism of wind power from the deflection of wind momentum by twice its angle (θ) of incidence on rotor blades. The transverse reaction needed to conserve deflected wind momentum provides the turning moment for turbine rotation. Action mechanics integrates impulsive wind action on turbine blades as differing torques (ʃmrvdθ/dt ≡ mv2 ) exerted on rotor surfaces at each radius. Windward torque (Tw) is estimated from rotor dimensions, the angle of wind incidence and radial action of wind impulses on the blade surfaces (also ʃmrvdθ/dt ≡ mv2). A leeward torque (Tb) is exerted as back reaction on turbine blades parallel to the plane of rotation of the blade. Net torque is then converted to potential power (Tw - Tb)Ω by the angular velocity (Ω) of the turbine rotors, a function of tip speed ratio to wind speed. Better predictions of limits to wind power can be made, by including control of optimal wind angle and blade length. An analysis of the equivalence of deflected air momentum on turbine blades or air foils for aircraft reveals that even the lifting action on air foils can be explained by the normal reaction to the momentum in an air stream, also deflected by an angle twice that (2θ) of incidence. Release of vortical field energy from laminar flow of air in winds as heat is predicted in turbulent wakes, possibly affecting achievement of maximum power output by wind farms. Significant heat release by downwind turbulence from vortical energy requires their careful location. Diligence demands that use of windfarms as sources of renewable energy should minimize any environmental impacts, such as drying of landscapes.

Carbon Disclosures and Industry Environment Sensitivity on Firm Performance
Authors: Isaboke Cyrus , Chen Yan , Bagonza Amon 
Published: August 2023

The study was conducted to explore carbon disclosures and industry environment sensitivity on firm performance. The study evaluates firm performance by examining both market and accounting-based measures and how they relate to carbon disclosures. The carbon disclosing sample is got from listed firms in China that reported their carbon emissions from 2010 to 2018. Results indicate that carbon disclosing firms experience declined firm performance following carbon disclosure of 4.13 % for ROA and 4.22% for the Q ratio following disclosure compared to the non-disclosing firms and there’s a decreased firm performance for the control sample of carbon non-disclosing companies, indication that environmental disclosures are linked with specific and costly risk disclosures which may castigate a company’s environmental strategies over specified time periods as disclosures tend to result to accountability.
We show why firm performance declined during the disclosure period despite prior research indicating that carbon-disclosing firms are characterized by increased firm performance. Despite the ever-increasing stringent measures and standards of environmental disclosures, environmentally sensitive industries are characterized by increased firm performance during the carbon disclosure period. We supplement the ever-expanding stream of research that evaluates the effects of carbon disclosures.

The Need for Occupational Therapist Eligibility for Formal Administrative Roles in Public School Systems
Authors: Franko Grace Anne 
Published: August 2023

Abstract
In 45 of 50 states, occupational therapists are not eligible to pursue formal administrative positions in public school systems (e.g., director of transition services, special education director) on the basis of state-level legislation and credentialing. Most state boards of education, however, recognize other related service providers (e.g., speech-language pathologists, social workers) as credentialed educators. Most states require education credentials to pursue further administrative credentials and, thus, administrative positions. Occupational therapists and other stakeholders lack awareness of this issue. In this column, I summarize the issue; identify occupational therapists’ qualifications for eligibility to pursue these positions; and provide solutions, primarily at the state level, to effect change so occupational therapists can be recognized as equals to their related service provider peers and use their unique skill set to influence public school communities as administrators.

Published: August 2023

IntroductionThe current study was conducted to evaluate the effects of the Minds-in-Motion Maze program on motor and cognitive abilities in school-aged children.MethodsThe experimental design used was a randomised controlled trial. Participants, belonging
to a public primary school, were 100 young children (50% boys) ranging from 6.00 to 8.50 years
old (7.32 ± 0.82 years in average). They were randomly assigned to experimental and control
groups (50 subjects/each), and two dropped out from each group. While the control group received

unstructured physical activity, the children in the experimental group engaged in the Minds-in-
Motion Maze vestibular stimulation program (24 weeks of a 30-minute structured PA on a daily
basis). A pre- and post-test were conducted to evaluate the performance in motor skills and
cognitive ability using the Bruininks-Oseretsky Test of Motor ProficiencyTM Second Edition,
complete form and Wechsler Intelligence Scale for Children, Fourth Edition.ResultsThe analysed data indicated that engaging in Minds-in-Motion Maze activities positively
influenced the motor and cognitive abilities among the children. The between-group analysis
exhibited strong significant improvement in the experimental group compared to the control group
(p &lt; 0.05), which did not show significant development. Boys outperformed girls on most tests,
notably as age increased. The within-groups analysis (experimental group) demonstrated significant
differences in the post-intervention gains of all motor and cognitive parameters (p &lt; 0.05).ConclusionsTaken together, the current results reinforce causal evidence for the effects of Minds-
in-Motion Maze based physical activity on improving both motor skills and cognitive aptitude in
school-aged children.

Abstract. We evaluate two high-resolution Lake Michigan air quality simulations during the 2017 Lake Michigan Ozone Study campaign. These air quality simulations employ identical chemical configurations but use different input meteorology. The AP-XM configuration follows the U.S. Environmental Protection Agency (EPA)-recommended modeling practices, whereas the YNT_SSNG employs different parameterization schemes and satellite-based inputs of sea surface temperatures, green vegetative fraction, and soil moisture and temperature. Overall, we find a similar performance in the model simulations of hourly and maximum daily average 8 h (MDA8) ozone, with the AP-XM and YNT_SSNG simulations showing biases of −11.42 and −13.54 ppbv (parts per billion by volume), respectively, during periods when the observed MDA8 was greater than 70 ppbv. However, for the two monitoring sites that observed high-ozone events, the AP-XM simulation better matched observations at Chiwaukee Prairie, and the YNT_SSNG simulation better matched observations at the Sheboygan Kohler-Andrae (KA) State Park. We find that the differences between the two simulations are largest for column amounts of ozone precursors, particularly NO2. Across three high-ozone events, the YNT_SSNG simulation has a lower NO2 column bias (0.17×1015 mol cm−2) compared to the AP-XM simulation (0.31×1015 mol cm−2). The YNT_SSNG simulation also has an advantage in that it better captures the structure of the boundary layer and lake breeze during the 2 June high-ozone event, although the timing of the lake breeze is about 3 h too early at Sheboygan. Our results are useful for informing an air quality modeling framework for the Lake Michigan area.
The impact of population ageing on the labour force participation rate in Spain
Authors: Cuadrado Pilar , Manuel Montero José , Fernández Cerezo Alejandro , Rodríguez Francisco José 
Published: August 2023

RationalePopulation ageing is one of the greatest structural challenges facing the Spanish economy. Foremost among its multiple effects is its contractionary impact on labour supply, which will foreseeably have major implications on both the functioning of the labour market and the potential growth or sustainability of public finances.Takeaways•Population ageing over the past decade has had an estimated negative impact of around 3.4 percentage points (pp) on Spain’s participation rate in 2022. This impact has been uneven by regions, with a sharper fall in the Cantabrian regions (Asturias, Cantabria and the Basque Country).•According to the latest National Statistics Institute’s population projections, the participation rate is set to drop a further 2.8 pp by 2030 owing to the continuing ageing process. Excluding the support of net immigration flows, the drop would be 1.6 pp greater.•In addition, the impact of ageing may deepen regional divergences, since the regions that have an older population and lower GDP per capita may be expected to experience the sharpest falls in the participation rate.
Co-administration of metformin and vitamin C or E in improves diabetes prognosis in streptozotocin-induced diabetes rats
Authors: Uchendu Adaeze , Omogbai Eric 
Published: August 2023

The prevalence of diabetes mellitus has increased astronomically in recent years. This has resulted in increased disease adjusted life years (DALYs), mortality and decrease in life expectancy. Some of the fall outs of diabetic disease in patients include hyperlipidaemia, oxidative stress, renal and hepatic dysfunction. This study investigated the combined effects of metformin with either vitamin C or E on hyperglycemia-induced hyperlipidemia, oxidative stress, renal and hepatic dysfunction.
Diabetes mellitus was induced in the animals fasted overnight with a single dose of streptozotocin (40 mg/kg, intraperitoneal). Animals with fasting blood glucose (FBG) levels >200 mg/dl after 48 hours of streptozotocin administration were marked diabetic and were randomly grouped into 6 groups of 5 diabetic rats each. Treatments were administered orally once daily for two weeks. FBG levels, and other parameters were determined.
The results showed that the various treatments significantly and comparably reduced the FBG levels on both day 7 (p<0.05, P<0.01) and day 14 (p<0.001). All the treatments significantly reduced hyperglycemia-induced increase in the levels of triglyceride (TG), total cholesterol (TC), alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine and malondialdehyde (MDA). The antioxidant enzyme activity of superoxide dismutase (SOD), glutathione reductase (GSH), and catalase (CAT) was enhanced by the combined effects of metformin and vitamin C or E. Vitamin E and combination of metformin and vitamin E did not prevent diabetes induced-weight loss throughout the study compared to diabetic control.
The findings have demonstrated that metformin and vitamin C co-administration exhibits synergistic effects on blood glucose lowering effect, antioxidant activity and potential advantage of preventing multi-organ damaging effects of type 2 diabetes.

Published: August 2023

Objective: This work proposes a model to implement digital transformation (DT) projects in companies. Material and Methods: The model's proposition was done by conducting individual interviews and focus group research on understanding and exploring the theme. Personal interviews were conducted with 15 professionals and focus groups with nine experts that experienced the DT process in their organizations. Based on these interviews, a preliminary model was proposed and validated in interviews with focus groups. All interviews took place in the same period of the COVID-19 pandemic. The research instrument explored aspects of strategy, competencies, digital technologies, and project management to determine how the DT process occurs and to define the final model. Results: Proposition of a model to operationalize DT projects following the organization's strategic direction. The model proposes that competencies enable change, using digital technologies as tools, and project management supports the project's strategy in line with the organizational strategy. The focus groups contributed to validating the model and proposing changes and improvements in the evaluation process in the model phases. The assessments were changed to occur recursively in the steps, allowing them to be evaluated throughout the project's life cycle to align with the project's and the organization's strategic assumptions. Contributions: The study presents a model to help companies of all sizes and activities to operationalize their DT projects. As a suggestion for future research, the proposed model can be used to develop and recommend new theories and develop models that meet the rapid transformations that occur in organizations.

<p>The chemical attributes and the total organic carbon stock of the soil, from crop-livestock integration systems for renovation of degraded pasture, with fodder sorghum, were evaluated in torpical Savanna. The experiment was carried out in randomized block design with five replications, in plots of 200 m<sup>2</sup>, in Brazilian Savanna. Treatments were (i) degraded pasture of <em>Brachiaria decumbens</em> cv. Basilisk; (ii) conventional renovation method for <em>B. brizantha</em> cv. Marandu (Control); (iii) Marandu sown in succession to sorghum monocrop for ensilage collected 0.45 m above the soil surface; and Marandu seeded simultaneously with the sorghum and harvested (iv) 0.15 and (v) 0.45 m above the soil surface. Carbon stock increases 19.9% in a short time (120 days) in the soil layer of 0.10-0.20 m for integrated crop-livestock systems treatments. All forms of renovation of pasture contributed to increases in macronutrients and reduction of Al in the soil. After 442 days, the higher soil fertility was observed for the Control tratamento indicating that this is a good method of renovation of pasture and it can be used where the crop-livestock can not.</p>

<p>Records of beef cows from a ranch in southern Mexico gave 1967 birth weights (BW), 1587 weaning weights adjusted to 210 days of age (AWW) and 2001 calving intervals (CI) for the comparison of the breed groups: Brahman (BR), Guzerat (GU), Nellore (NE) and crosses born to zebu dams by Brown Swiss sires. Animals were fed mainly pasture. Data were analysed using general linear procedures. The statistical model that described the data for BW and AWW included the fixed effects of breed group (BR, GU, NE, BS x BR, BS x GU and BS x NE); year of birth or calving (2005 to 2014), season of parity of the cow (dry, rainy, windy), sex of the calf (female or male), parity (1 to =&gt;8) and the simple interaction of year x season of birth or calving. The model for CI was similar to the previous one, except that only the Zebu purebreds were included. The overall means and standard deviations for BW, AWW and CI were 33.5<span style="text-decoration: underline;">+</span>0.75 kg, 178.9<span style="text-decoration: underline;">+</span>19.7 kg and 456.4<span style="text-decoration: underline;">+</span>79.2 days. All effects included in the model had significant effect on BW and AWW, but season and sex on CI. The smallest least squares means for BW corresponded to the cross of BR x NE and the largest to the cross of BS x BR (33.3 and 33.7 kg, respectively); whereas the lowest and largest least squares means for AWW corresponded to the NE (173.8 kg) and BS x BR (191.8 kg). NE cows had shorter CI than BR and GU cows (413.9, 446.2 and 481.3, respectively). Male calves weighed more at birth and weaning than females. Year x season interaction indicate that season effects on performance of calves or cows were not similar throughout the years studied. </p>
