Pure-Tone Thresholds, Speech Understanding, and Their Correlates in Samples of Men of Different Ages1
1986
Pure-tone thresholds and speech understanding were studied in three samples of men of different ages (31-35, 51-55 and 71-75 years). The air-conducted pure-tone thresholds were measured at 125-8,000 Hz and speech understanding by the help of interrupted and masked speech tests. The audiological measures were related to measures of other sensory functions, psychomotor speed, cognitive functions, psychic well-being, occupational and educational background and health. The results indicated a clear decrement in all audiological measures when proceeding from younger to older age groups. The results of the speech-understanding tests correlated significantly with the pure-tone thresholds both at 4…
Effect of body weight on the volume of distribution of theophylline.
1988
The volume of distribution (Vd) of theophylline and the relevant aminophylline loading dose (LD) are usually calculated on the basis of total body weight (TBW). In obese subjects it has been suggested that lean or ideal body weight (IBW) is the best predictor. In a sample of 40 acutely ill asthmatic patients (aged 22 to 78 yr, weighing 45 to 176 kg) we measured Vd and found that (1) it increases with TBW, (2) it cannot be accurately predicted from either TBW or IBW alone by a simple regression analysis. Power functions have been usefully applied in comparing the pharmacokinetics of animal species, including humans, with different body mass. In our sample, data were best fitted by the equati…
Informal caregiving burden in advanced non-small cell lung cancer: the HABIT study.
2007
Introduction This study's aim was to assess economic data regarding the home assistance burden for advanced non-small cell lung cancer (NSCLC) patients in Italy. Patients and Methods One hundred four NSCLC patients in second-line chemotherapy (2LC) or in supportive therapy (ST) were enrolled in 18 Italian oncology departments and were observed for 3 months. The main caregiver's workload was assessed monthly by a task scale; other caregivers' activities were also registered. Eastern Cooperative Oncology Group performance status was assessed by physicians, and patients completed the Lung Cancer Symptoms (LCS) subscale. Formal caregiving time was valued according to market prices; informal car…
Phase II study of pemetrexed and cisplatin plus cetuximab followed by pemetrexed and cetuximab maintenance therapy in patients with advanced nonsquam…
2013
Abstract Objectives The aim was to determine if combined pemetrexed, cisplatin, and cetuximab was efficacious and safe as first-line treatment in advanced nonsquamous non-small cell lung cancer (NSCLC). Patients and methods In this single-arm, multicenter clinical trial, patients with Stage IIIB/IV nonsquamous NSCLC received first-line therapy consisting of pemetrexed (500mg/m 2 ) and cisplatin (75mg/m 2 ) on Day 1 (21-day cycles) plus weekly cetuximab (400mg/m 2 loading dose, then 250mg/m 2 ) for 4–6 cycles. Non-progressing patients received maintenance therapy consisting of pemetrexed and cetuximab as above until disease progression. All patients received vitamin supplementation, dexameth…
A simple noninvasive pressure–time index at the mouth to measure respiratory load during acute exacerbation of COPD A comparison with normal voluntee…
2003
We assessed the validity of the pressure-time index (PTI) measured at the mouth as a noninvasive and simplified alternative to conventional tension-time index for assessing respiratory load and inspiratory muscle force reserve. PTI was measured within 48 h of hospital admission and at 24 h before discharge in 37 consecutive patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) using the equation PTI = (P(awo)/MIP)(T(I)/T(T)) 100, where P(awo) is the mean airway pressure measured at the mouth, MIP the maximal inspiratory pressure, and T(I)/T(T) the inspiratory time (T(I)) to total cycle length (T(T)) ratio. Controls were 30 normal volunteers with similar anthropome…
Load match and grid interaction optimization of a net zero energy building through electricity storage: An Italian case-study
2016
The study aims at applying of Load Match and Grid Interaction indexes to a Net Zero Energy Building in order to optimize the performances of its energy systems. The case study is a modular prefabricated house that uses solar energy (photovoltaic) and natural gas (Fuel Cell) as energy sources and equipped with an Energy Management System addressing the optimal energy use.
An optimal operating strategy for combined RES–based Generators and Electric Storage Systems for load shifting applications
2013
This paper focuses on an optimal operating strategy of combined RES-based generators and electric storage systems for small/medium-scale public facilities. The operating strategy can be used in load shifting applications in response to a time-of-use (TOU) rate design with differential pricing for on- and off-peak usage. Load shifting applications can be exploited by customers using battery energy storage systems (BESS) in order to reduce their electricity bill, charging the storage when off-peak time periods are applied and discharging it during on-peak periods, when electricity energy prices are high. The operating strategy is implemented within a bidirectional converter that provides an i…
The 1,3-dipolar cycloaddition of 1H-pyridinium-3-olate and 1-methylpyridinium-3-olate with methyl acrylate: a density functional theory study
2010
The 1,3-dipolar cycloaddition reaction of 1-substituted pyridinium 3-olates with methyl acrylate is studied using density functional theory (DFT) method at the B3LYP/6-31G(d) level. The molecular mechanisms of the possible stereo- and regio-chemical pathways are characterized and explored. Solvent effects are also evaluated by the polarizable continuum model (PCM). Analysis of the results shows that there are relevant differences in the reaction pathways between the gas phase and with solvent. Only results in solvent phase are in accord with literature experimental results where 6-substituted 8-azabicyclo[3.2.1]oct-3-en-2-ones are formed preferentially. These polar cycloaddition reactions t…
A Deep Learning Approach for Energy Efficient Computational Offloading in Mobile Edge Computing
2019
Mobile edge computing (MEC) has shown tremendous potential as a means for computationally intensive mobile applications by partially or entirely offloading computations to a nearby server to minimize the energy consumption of user equipment (UE). However, the task of selecting an optimal set of components to offload considering the amount of data transfer as well as the latency in communication is a complex problem. In this paper, we propose a novel energy-efficient deep learning based offloading scheme (EEDOS) to train a deep learning based smart decision-making algorithm that selects an optimal set of application components based on remaining energy of UEs, energy consumption by applicati…
Effects of heavy barbell hip thrust vs back squat on subsequent sprint performance in rugby players
2020
The objective of this research was to compare the effect of Post-Activation Performance Enhancement (PAPE) exerted on the back squat (BS) versus the barbell hip thrust (HT) on the sprint performance (5- and 10-m). 17 male amateur rugby players participated in the study (age 22.14 ± 2.52 years; body mass 81.06 ± 9.6 kg; height 1.78 ± 0.05 m). All participants performed a dynamic maximum strength test (3RM) in BS and HT at maximum speed. Two randomized sessions were performed inducing PAPE using BS or HT trough three series with three repetitions at 85% 1RM eight minutes before the sprint tests. An ANOVA of repeated measurement, found no differences in the time for 5-m (F = 0.398, P = 0.537, …
