Dynamic thermo-mechanical responses of road-soft ground system under vehicle load and daily temperature variation

A complete road-soft ground model is established in this paper to study the dynamic responses caused by vehicle loads and/or daily temperature variation.A dynamic thermo-elastic model is applied to capturing the behavior of the rigid pavement,the base course,and the subgrade,while the soft ground is characterized using a dynamic thermo-poroelastic model.Solutions to the road-soft ground system are derived in the Laplace-Hankel transform domain.The time domain solutions are obtained using an integration approach.The temperature,thermal stress,pore water pressure,and displacement responses caused by the vehicle load and the daily temperature variation are presented.Results show that obvious temperature change mainly exists within 0.3 m of the road when subjected to the daily temperature variation,whereas the stress responses can still be found in deeper places because of the thermal swelling/shrinkage deformation within the upper road structures.Moreover,it is important to consider the coupling effects of the vehicle load and the daily temperature variation when calculating the dynamic responses inside the road-soft ground system.

Preweaning period is a critical window for rumen microbial regulation of average daily gain in Holstein heifer calves

Background Rumen bacterial groups can affect growth performance,such as average daily gain(ADG),feed intake,and efficiency.The study aimed to investigate the inter-relationship of rumen bacterial composition,rumen fermentation indicators,serum indicators,and growth performance of Holstein heifer calves with different ADG.Twelve calves were chosen from a trail with 60 calves and divided into higher ADG(HADG,high pre-and post-weaning ADG,n=6)and lower ADG(LADG,low pre-and post-weaning ADG,n=6)groups to investigate differences in bacterial composition and functions and host phenotype.Results During the preweaning period,the relative abundances of propionate producers,including g_norank_f_Butyricicoccaceae,g_Pyramidobacter,and g_norank_f_norank_o_Clostridia_vadin BB60_group,were higher in HADG calves(LDA>2,P<0.05).Enrichment of these bacteria resulted in increased levels of propionate,a gluconeogenic precursor,in preweaning HADG calves(adjusted P<0.05),which consequently raised serum glucose concentrations(adjusted P<0.05).In contrast,the relative abundances of rumen bacteria in post-weaning HADG calves did not exert this effect.Moreover,no significant differences were observed in rumen fermentation parameters and serum indices between the two groups.Conclusions The findings of this study revealed that the preweaning period is the window of opportunity for rumen bacteria to regulate the ADG of calves.

Improvement of Activities of Daily Living (ADL) for Patients Treated in Skilled Nursing Facilities (SNFs)

Background: Self-care tasks or activities of daily living (ADL)’s performance are often disrupted after an older adult sustains an injury or illness, which can be a determining factor for discharge placement after hospitalization, or it can determine the level of assistance required after discharge from a skilled nursing facility (SNF). We believe that comprehensive rehabilitation can improve a patient’s overall functioning during their short term stay in SNFs. The purpose of this study is to determine if an individual’s level of independence improved after admission to a skilled nursing facility and procurement of rehabilitation services. Methods: This study retrospectively reviewed 4612 nursing home patients in California who underwent rehabilitative services at skilled nursing facilities to determine how the patients responded to their environments, therapy interventions, and any other additional supportive measures. The records of patients who were admitted for short-term rehabilitation were reviewed in a blinded fashion, looking specifically at Section GG of the Minimum Data Set (MDS). Self-Care Section GG scores recorded by rehabilitative staff provide objective data and measure patients’ levels of assistance that were required. Each activity is scored from 1, being completely dependent, to 6, being entirely independent, with varying levels of assistance with scores in between. The admission scores versus the discharge scores can be compared to determine if a patient improved their level of functioning upon discharge. Results: Utilizing the Pearson’s correlation coefficient, a strong correlation of improvement in ADL performance on Section GG between the admission and discharge scores was identified, implying significant improvement in functional independence upon discharge. The average percent improvement for Managed Care patients was ~35.4% and ~39.4% for Medicare patients. Conclusions: The results support the benefits of rehabilitation services in skilled nursing facilities, and the data suggests that admission scores can be used as a predictive tool for functional outcomes.

Estimation of Return Level for Maximum Daily and Hourly Precipitation in Nagano Prefecture, Japan, Using the Extreme Value Theory

The weather in Nagano Prefecture, Japan, can be roughly classified into four types according to principal component analysis and k-means clustering. We predicted the extreme values of the maximum daily and hourly precipitation in Nagano Prefecture using the extreme value theory. For the maximum daily precipitation, the vales of ξ in Matsumoto, Karuizawa, Sugadaira, and Saku were positive;therefore, it has no upper bound and tends to take large values. Therefore, it is dangerous and caution is required. The values of ξ in Nagano, Kisofukushima, and Minamishinano were determined to be zero, therefore, there was no upper limit, the probability of obtaining a large value was low, and caution was required. We predicted the maximum return levels for return periods of 10, 20, 50, and 100 years along with respective 95% confidence intervals in Nagano, Matsumoto, Karuizawa, Sugadaira, Saku, Kisofukushima, and Minamishinano. In Matsumoto, the 100-year return level was 182 mm, with a 95% CI [129, 236]. In Minamishinano, the 100-year return level was 285 mm, with a 95% CI [173, 398]. The 100-year return levels for the maximum daily rainfall were 285, 271, and 271 mm in Minamishinano, Saku, and Karuizawa, respectively, where the changes in the daily maximum rainfall were larger than those at other points. Because these values are large, caution is required during heavy rainfall. The 100-year return levels for the maximum daily and hourly precipitation were similar in Karuizawa and Saku. In Sugadaira, the 100-year return level for a maximum hourly rainfall of 107.2 mm was larger than the maximum daily rainfall. Hence, it is necessary to be careful about short-term rainfall events.

Estimating daily actual evapotranspiration of a rice–wheat rotation system in typical farmland in the Huai River Basin using a two-step model and two one-step models

The objective of this study is to evaluate the performance of three models for estimating daily evapotranspiration(ET) by employing flux observation data from three years(2007, 2008 and 2009) during the growing seasons of winter wheat and rice crops cultivated in a farmland ecosystem(Shouxian County) located in the Huai River Basin(HRB), China. The first model is a two-step model(PM-Kc);the other two are one-step models(e.g., Rana-Katerji(R-K) and advection-aridity(AA)). The results showed that the energy closure degrees of eddy covariance(EC) data during winter wheat and rice-growing seasons were reasonable in the HRB, with values ranging from 0.84 to 0.91 and R2 of approximately 0.80. Daily ET of winter wheat showed a slow decreasing trend followed by a rapid increase, while that of rice presented a decreasing trend after an increase. After calibrating the crop coefficient(Kc), the PM–Kc model performed better than the model using the Kc recommended by the Food and Agricultural Organization(FAO). The calibrated key parameters of the R-K model and AA model showed better universality. After calibration, the simulation performance of the PM-Kc model was satisfactory. Both the R-K model and AA model underestimated the daily ET of winter wheat and rice. Compared with that of the R-K model, the simulation result of the AA model was better, especially in the simulation of daily ET of rice. Overall, this research highlighted the consistency of the PM-Kc model to estimate the water demand for rice and wheat crops in the HRB and in similar climatic regions in the world.

Effectiveness of daily interruption of sedation in sedated patients with mechanical ventilation in ICU: A systematic review

Purpose:To evaluate the effectiveness of daily sedation interruption in patients with mechanical ventilation in intensive care unit(ICU).Methods:The randomized controlled trials(RCTs)on the application of daily interruption of sedation in sedated patients with mechanical ventilation in ICU were collected through databases including Cochrane library,MEDLINE,Web of Knowledge,Embase,CNKI,CBM and VIP Data.Two reviewers independently assessed the quality of studies and extracted the data.Meta-analysis was conducted on the included studies.Results:Eight RCTs involving 757 patients were included.The daily sedation interruptions could shorten the duration of mechanical ventilation(Z=5.36,p<0.0001),length of stay(Z=2.93,p=0.003<0.05)and reduce the rate of tracheotomy(Z=3.97,p<0.00001)in these patients.Additionally,daily sedation interruption was not associated with increased rate of unplanned extubation by the patients(Z=0.53,p=0.6<0.05).Conclusion:The application of daily interruption of sedation in patients with mechanical ventilation in ICU is safe and effective.

Interventions to improve daily activity in individuals with COPD and CHF: A systematic review

Introduction: The purpose was to systematically review the literature regarding interventions to improve daily activity in individuals with chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF). Methods: Articles found by searching CINAHL Plus Full-Text, PubMed, and PsycINFO databases were included in the review if the study examined the effect of exercise- and/or psychosocial-based interventions on daily activity in individuals with COPD or CHF. Article selection, data extraction, and evaluation of methodological rigor and quality were performed by two independent reviewers. Nine articles for COPD and seven articles for CHF met the inclusion criteria and were used in this review. Results: Only four of nine studies in COPD and two of seven studies in CHF resulted in improvement in daily activity, and of those, all but one study included a psychosocial-based intervention. Improvements in daily activity did not occur concurrently with changes in other outcomes such as exercise performance, quality of life, functional status, or anxiety/depression in COPD or CHF. Conclusions: Exercise-based interventions serve a limited, if any, role in improving daily activity in individuals with COPD and CHF. Disrupting the cycle of inactivity and deconditioning requires more than just addressing the deconditioning aspect of this cycle. Psychosocial-based interventions are a promising, but under-investigated, intervention.

Ayurveda daily regimen practices (Dinacharya): a scientific system model approach suitable as a quaternary prevention strategy for non-communicable diseases

Background:Non-communicable or lifestyle diseases replaced infectious diseases at the end of the 20th century as the primary burden of disease worldwide,marking the epidemiological transition.The industrial revolution and technological advancements,as well as packaged processed foods,have greatly affected lifestyle,causing adverse health effects through chronic,low-level,and systemic inflammation known as“metaflammation”.The main contributors to lifestyle-related diseases are poor eating habits,physical inactivity,poor posture,and a disturbed biological clock.The study on lifestyle changes indicates that comprehensive lifestyle changes can prevent disease and reverse the progression of diseases like diabetes,heart disease,stroke,prostatic cancer and breast cancer.The concept of disease prevention is getting wider acceptability owing credit to early disease detection,better treatment modalities and reduced financial implications.However,the possible harms of over-testing and over-medicalization have led to the propagation of Quaternary prevention strategies.Ayurveda,too propagates the principle of health preservation,promotion,and disease prevention,along with early diagnosis and holistic disease management strategies,incorporating dietary and lifestyle components such as Dinacharya(daily regimen practices),Ritucharya(seasonal regimen practice).This paper critically explores the scientific relevance behind these ascribed daily regimen practices(Dinacharya)and their suitability as a quaternary prevention strategy and presents it for dialogue and research to the scientific community.Method:The classical texts of Ayurveda and the internet search engines were explored with keywords of relevant terms such as“research”“benefit”and“role in health”combined with the Ayurveda daily regimen terms and their English equivalents as provided in brackets and their different combinations and permutations,along with net surfing and hand search.The relevant articles were stored and screened for relevance and the matter is presented systematically for scientific deliberation principal findings–Ayurveda recognized the temporal effects of chronobiological cycles on human health and accordingly devised the daily regimen schedule,delineating the principles for healthy living and harmonization.The daily regimen practices of Ayurveda like timely sleeping,waking up early in the morning,proper defecation,massage,exercise,occupation,social bonding,appropriate dietary practices,etc.adopt a system biology approach with synchronization of chronobiological cycles,mind-body integration,system performance,and epigenetics,apart from other possible approaches and have considerable scientific evidence for the effectiveness as a quaternary prevention strategy.Conclusion:The adoption of these practices in the daily routine may play a crucial role in health preservation and disease prevention at all levels of preventive domains.However,prospective large scale,long-duration randomized controlled trials are yet needed to scientifically further establish the validity of the same.

Homogenised Monthly and Daily Temperature and Precipitation Time Series in China and Greece since 1960

In this paper,we describe and analyze two datasets entitled“Homogenised monthly and daily temperature and precipitation time series in China during 1960–2021”and“Homogenised monthly and daily temperature and precipitation time series in Greece during 1960–2010”.These datasets provide the homogenised monthly and daily mean(TG),minimum(TN),and maximum(TX)temperature and precipitation(RR)records since 1960 at 366 stations in China and 56stations in Greece.The datasets are available at the Science Data Bank repository and can be downloaded from https://doi.org/10.57760/sciencedb.01731 and https://doi.org/10.57760/sciencedb.01720.For China,the regional mean annual TG,TX,TN,and RR series during 1960–2021 showed significant warming or increasing trends of 0.27℃(10 yr)^(-1),0.22℃(10 yr)^(-1),0.35℃(10 yr)^(-1),and 6.81 mm(10 yr)-1,respectively.Most of the seasonal series revealed trends significant at the 0.05level,except for the spring,summer,and autumn RR series.For Greece,there were increasing trends of 0.09℃(10 yr)-1,0.08℃(10 yr)^(-1),and 0.11℃(10 yr)^(-1)for the annual TG,TX,and TN series,respectively,while a decreasing trend of–23.35 mm(10 yr)^(-1)was present for RR.The seasonal trends showed a significant warming rate for summer,but no significant changes were noted for spring(except for TN),autumn,and winter.For RR,only the winter time series displayed a statistically significant and robust trend[–15.82 mm(10 yr)^(-1)].The final homogenised temperature and precipitation time series for both China and Greece provide a better representation of the large-scale pattern of climate change over the past decades and provide a quality information source for climatological analyses.
