Résumé :

Abstract A healthy diet is essential to various health outcomes that are common among minority aging populations. To explore frequencies and correlates of food consumption among U.S. Chinese older adults, this study used data from the Population-based Study of Chinese Elderly (PINE) collected in Chicago during 2015-2017 (N=3053). Food consumption frequencies of five food groups (vegetables, fruits, grains, protein foods, and dairy) were assessed by a validated 48-item food frequency questionnaire. All responses of consumption frequency were transformed to “times per day” and weighted by report

Résumé :

This study aimed to determine consumers’ liquid choices, their consumption frequencies and habits. The study was conducted on 332 individuals aged between 16 and 30 (mean age: 20.7 ± 3.1 years). The most important factors that affect consumers’ liquid choices are tastiness (74.7%), easy accessibility (71.4%) and being a continuously consumed beverage (69.3%), respectively. Of the participants, 78.0% consumed liquids at meals, 66.3% of them started the day with a drink, 65.4% controlled alcohol content in energy drinks, 62.3% consumed water while eating, 50.0% consumed water in the recommended

Food-based recommendations (FBR) developed using linear programming generally use dietary intake and energy and nutrient requirement data. It is still unknown to what extent the availability and selection of these data affect the developed FBR and identified problem nutrients. We used 24 h dietary recalls of 62 Kenyan children (4–6 years of age) to analyse the sensitivity of the FBR and problem nutrients to (1) dietary intake data, (2) selection criteria applied to these data and (3) energy and nutrient requirement data, using linear programming (Optifood©), by comparing a reference scenario w

At speeds greater than 1.6 ms-1 the rate of metabolic power consumption was independent of hopping speeds. Blood lactate levels within the speed range where VO2 was independent of speed showed a mean increase of 4.8 mmol l-1. During bipedal hopping, the frequencies of breathing and limb movement are phase-locked in the ratio of 1:1. Inspiration begins as the animal leaves the ground and may be a passive proce

In our longitudinal study, we followed 91 participants (21.0 ± 2.2 years) over a period of 1 year (373 ± 19 days) and monitored tooth wear with an intraoral scanner.

Moreover, an active feedback resistor is introduced into the active inductor for fine-tuning of the inductance. The feedback resistor also affects the equivalent resistance of the active inductor; therefore, wide inductance tuning and low power consumption can be obtained by optimizing the resistor.

Résumé :

A central implication of life-cycle models is that agents smooth consumption. We review the empirical evidence on smoothing at frequencies from within the year up to across a lifetime. We find that life-cycle models--particular those which incorporate realistic features of markets and goods--have more empirical successes than failures. We also show that some apparent deviations from theoretical predictions imply very small welfare losses for agents. Finally, we emphasize that the coherence of life-cycle models imposes an important discipline when incorporating new features into models.

ABSTRACT: Considering Africa's increasing electricity demands and the pivotal role of electricity in socio-economic development, this study addresses a research gap in understanding the stochastic properties of per capita electricity consumption in African contexts. Through examining the integration properties of per capita electricity consumption across 19 African countries, the research determines whether 'shocks' yield transitory or permanent effects, aiding policy formulation and future demand forecasting. Annual electric power consumption data (1971 – 2014) (kWh per capita) from the WDI a

Results of bench tests of tractor diesel engines in transient regimes are presented. The frequencies of load oscillations on motor shaft, attended by the increased fuel consumption and the high rate of friction pairs wear are determined. Reasons of occurrence of resonant phenomena, increased fuel consumption and high wear rate are established. Measures reducing the negative effects are recommended.

Résumé :

This study examined the nexus between economic growth, energy consumption, and the environment with the moderating role of agricultural value addition and forest in Africa based on data sourced from 1980 to 2019. We employed both the time domain and frequency domain panel Granger causality estimation techniques to compare results across the different horizons. Extant literature suggests the inability of time domain estimation techniques to account for causality at different frequencies. The study also accounts for the nexus among our variables both at the single-country and multi-country level

There is a longstanding interest in the relationship between diet and hot flash symptoms during midlife, especially in whether phytoestrogens ease menopausal symptoms. The purpose of this study was to examine hot flashes, night sweats, trouble sleeping, and vaginal dryness in relation to the intake of foods rich in phytoestrogens among Bangladeshi women aged 35 to 59 years who were living either in Sylhet, Bangladesh (n = 157) or as migrants in London (n = 174). Consumption ranges for phytoestrogens were constructed from food frequencies. We hypothesized that diets rich in isoflavones, lignans

Abstract Introduction One of the important nonphotic zeitgebers is food consumption. The timing of food consumption in relation to melatonin onset has been reported to be associated with fat proportion and BMI. Irregular meal timing along with irregular sleep schedules due to shift work would increase the metabolism problem as well as influencing sleep problems. The aim of the study is to evaluate the meal timing and food consumption in shift workers. Methods The nurses with 3-rapid rotating shifts were enrolled to keep food diaries for two weeks including all three shift schedules. They fille

The existing SRAM cell design of consumes more power at higher frequencies. In the proposed work, power reduction is achieved in various radiation-hardened SRAM cell designs which is based on power gating technique. Hence, the power gated voltage (VDD) design technique is employed to reduce power consumption.

The temperature range for consuming hot drinks includes temperatures that can damage cells on the tongue. We hypothesized that the consumption of very hot drinks can lead to a decrease in the ability to perceive low concentrations of tastants. We evaluated the ability to perceive low concentrations of five prototypical sapid compounds in 42 women and 40 men aged 18–65. A questionnaire made it possible to collect the usual frequencies (number of unit/day) and consumption temperature levels (medium hot/very hot) for four very common hot drinks (coffee, tea, herbal infusions, and hot chocolate).
