Reducing Extended Hospital Lengths of Stay
2024年
In the United States, the costs of health care have become a major burden for the health care system. In order to address this problem, the hospitals of Syracuse, New York, developed programs to provide subacute and complex care. The Subacute programs provided patient transportation services for dialysis and other types of care outside hospitals. They also developed programs for services such as intravenous therapy in nursing homes. The Complex Care Programs, such as intravenous therapy and mental health services, have provided alternatives to extended care in hospitals. During the past five years, utilization of these programs has varied, declining between 2019 and 2022, and then increasing between 2022 and 2024. The programs have avoided the need for 1530 - 2974 patient days in hospitals. The programs saved the Syracuse hospitals approximately $600 per inpatient day. This amounted to savings of $918,000 - $1,784,400 per year. These programs demonstrated how relatively small mechanisms can save large amounts of health care resources.

Reducing Electrical Consumption in Stationary Long-Haul Trucks
2024年
On average, long-haul trucks in the U.S. use approximately 667 million gallons of fuel each year just for idling. This idling primarily facilitates climate control operations during driver rest periods. To mitigate this, our study explored ways to diminish the electrical consumption of climate control systems in class 8 trucks through innovative load reduction technologies. We utilized the CoolCalc software, developed by the National Renewable Energy Laboratory (NREL), which integrates heat transfer principles with extensive weather data from across the U.S. to mimic the environmental conditions trucks face year-round. The analysis of the CoolCalc simulations was performed using MATLAB. We assessed the impact of various technologies, including white paint, advanced curtains, and Thinsulate insulation on reducing electrical demand compared to standard conditions. Our findings indicate that trucks operating in the eastern U.S. could see electrical load reductions of up to 40%, while those in the western regions could achieve reductions as high as 55%. Such significant decreases in energy consumption mean that a 10 kWh battery system could sufficiently manage the HVAC needs of these trucks throughout the year without idling. Given that many long-haul trucks are equipped with battery systems of around 800 Ah (9.6 kWh), implementing these advanced technologies could substantially curtail the necessity for idling to power air conditioning systems.

低热水泥与减水剂的相容性研究
2024年
本文研究了低热水泥与聚羧酸减水剂和萘系减水剂相容性的差异,并以普通硅酸盐水泥作为基准,通过流动度以及经时损失和流变性能评价了水泥与减水剂的相容性。结果表明:在低热浆体中,萘系减水剂的饱和掺量点大于聚羧酸减水剂;低热水泥展现出不弱于普通硅酸盐水泥的良好相容性,并且低热水泥与聚羧酸减水剂的适应性要好于萘系减水剂;含减水剂的低热水泥净浆的流变特性符合Bingham模型,掺入聚羧酸减水剂的低热水泥浆体呈现为典型的牛顿流体,而掺入萘系减水剂的低热水泥浆体呈现为剪切稀化流体。

Assessing Community Health Interventions in Reducing Infant and Child Mortality in the Southeastern Benin
2024年
Background: To reduce infant and child mortality in Benin, a package of high-impact interventions per healthcare level was implemented in 2009. This study aimed to assess the quality of community-based health interventions in reducing infant and child mortality within the municipality of Pobè in southeastern Benin. Methods: This was a cross-sectional evaluative study carried out in November 2021 focused on children aged 0 - 59 months, their mothers, health workers, community facilitators, community health workers and the Town Hall health focal point. Mothers and their children were targeted by cluster sampling, and exhaustive selection was used to recruit all other participants. Predetermined scores based on rating criteria were used to assess the quality of community health interventions using the “input, process and outcome” of Donabedian approach. Results: Over 300 mother-child couples, 46 community health workers, 7 health agents, 1 community facilitator and 1 health focal point from Pobè town hall were surveyed. Intervention quality was judged as “average”, with a score of 73.80%. The “inputs” and “outcomes” components were the weakest links. Conclusion: Improving access to the inputs needed by community health workers can enhance the quality of PIHI interventions.

The Criteria for Reducing Centrally Restricted Three-Body Problem to Two-Body Problem
2024年
Our Solar System contains eight planets and their respective natural satellites excepting the inner two planets Mercury and Venus. A satellite hosted by a given Planet is well protected by the gravitational pertubation of much heavier planets such as Jupiter and Saturn if the natural satellite lies deep inside the respective host Planet Hill sphere. Each planet has a Hill radius aH and planet mean radius RP and the ratio R1=RP/aH. Under very low R1 (less than 0.006) the approximation of CRTBP (centrally restricted three-body problem) to two-body problem is valid and planet has spacious Hill lobe to capture a satellite and retain it. This ensures a high probability of capture of natural satellite by the given planet and Sun’s perturbation on Planet-Satellite binary can be neglected. This is the case with Earth, Mars, Jupiter, Saturn, Neptune and Uranus. But Mercury and Venus has R1=RP/aH =0.01 and 5.9862 × 10-3 respectively hence they have no satellites. There is a limit to the dimension of the captured body. It must be a much smaller body both dimensionally as well masswise. The qantitative limit is a subject of an independent study.

聚羧酸系减水剂对普通硅酸盐水泥及硫铝酸盐水泥性能的影响研究
2024年
本研究选取普通硅酸盐和硫铝酸盐水泥体系作为研究对象,通过调配聚羧酸减水剂的添加量,系统地研究其对这两种水泥体系施工性能的影响。试验发现,聚羧酸减水剂具有良好的减水性。随着PCE掺量的增加,两种水泥体系的凝结时间增大;两种水泥的流动性随着PCE掺量的增加而增大,PCE掺量分别为0.50%和0.40%时,其减水率达到饱和点;在减水率达到饱和点之前,两种水泥的抗压强度不断增加;聚羧酸减水剂与两种水泥都具有良好的适配性。
