Abstract:
Reduction processes of the cross-sectional area at a river mouth were investigated on the basis of numerical simulations and field measurements, in order to predict the possibility of closing of the mouth of the Samegawa River, Fukushima, Japan. As a result, it was found that the decrease in tidal prism, induced by a reduction of the cross-sectional area, had an important effect on the closing of the river mouth. By considering this effect and estimating the sediment transport rate properly, a practical prediction model was successfully established for simulating the reduction processes of the

Mechanical properties of concrete are size dependent. While many reports have discussed the size effect of the test specimen on the static properties of concrete, research on the effect of cross-sectional dimensions of the concrete beams on its impact performance is still scarce. This research experimentally evaluates the relationship between the cross-sectional dimensions and orientation of the concrete beam specimens on their impact performance.

Purpose This paper aims to study the yarn cross-section shape which is a very important yarn physical parameter and has a dominant effect on the physical structure of the yarn. Four factors affecting the yarn cross section, i.e. twist multiplier, Roving hank, spinning system and doubling technique, were investigated. Design/methodology/approach In past researches, the yarn cross-sectional area was calculated by considering any one yarn radius giving the approximate yarn cross-sectional area by assuming the yarn as a circular one.

Antibacterial polypropylene cross-sectional shape fibers were melt spun with adding nano ZnO and modified chitosan. Two types of fiber cross-section, round and worm cross-sectional shape were studied including with nano ZnO and modified chitosan loading. Antibacterial properties, surface area, and fiber crystalization were investigated. The surface area of the fiber and antibacterial properties were directly related to the cross-sectional shape. The greater antibacterial properties was found at lower modified chitosan loading compared ZnO.

It is well known that maximal eccentric exercise induces muscle damage, especially when it is performed for the first time. However, muscle damage is attenuated in subsequent bouts of the same or similar exercise, which is known as the repeated bout effect. One of the factors affecting the magnitude of muscle damage and the repeated bout effect is the number of eccentric contractions; however, it is unknown if different set-repetition configurations with the same number of eccentric contractions would result in different magnitudes of muscle damage and adaptation.

In this study, we examined how hill running affects the Achilles tendon, which is a common location for injuries in runners. Twenty females ran for 10 min on three randomly selected grades (-6%, 0%, +6%). Achilles tendon (AT) cross-sectional area (CSA) was imaged using Doppler ultrasound and peak vertical forces were analyzed using high-speed (240 Hz) videography. A metabolic cart and gas analyzer ensured a similar metabolic cost across grades. Data were analyzed using a forward selection regression. Results showed a decrease in AT CSA from pre-run to post-run (p = .0001). Peak vertical forces

To lowest order, the wavenumber depends only on the ratio of cross-sectional areas and the properties of the constituent media, and surprisingly not on the material configuration in the cross-section.

Full text
Abstract:
Corrosion in the girders of steel girder bridges often occurs due to the deicing salts, water, and other debris that leak through the deck joints into the web and bottom flange at the girder ends. Corrosion causes loss of cross-sectional area leading to a reduction in section properties of the member, which eventually results in a reduction in structural resistance against shear and bearing. In this study, seven full-scale tests were performed on decommissioned steel girders acquired from bridges scheduled for demolition in Indiana. Two of the four girders had severe corrosion with cracks and

Abstract:
This paper takes advantage of several reforms that provide time and cross sectional variation to identify the effects of unemployment insurance and severance payments on the duration of unemployment and on the separation probability in Argentina. Administrative data permits analysis of the duration of unemployment of covered spells with detailed information about transfers and their duration, while household surveys permit the study of separation probability and transitions to informal jobs, which are not observed in administrative data. It is found that unemployment duration increases signifi

Abstract:
This paper uses U.S. loan-level credit register data and the 2018–2019 Trade War to test for the effects of international trade uncertainty on domestic credit supply. We exploit cross-sectional heterogeneity in banks’ ex-ante exposure to trade uncertainty and find that an increase in trade uncertainty is associated with a contraction in bank lending to all firms irrespective of the uncertainty that the firms face. This baseline result holds for lending at the intensive and extensive margins. We document two channels underlying the estimated credit supply effect: a wait-and-see channel by which

Abstract:
In this working paper the authors present evidence on the reliability of propensity score matching to estimate the bias associated with the effect of treatment on the treated, exploiting the availability of experimental data from a Mexican antipoverty program (PROGRESA: Programa de Educación, Salud y Alimentación). The data comes from several outcomes such as food expenditure and child schooling and labor. The methodology compares the results of the experimental impact estimator with those using matched samples drawn from a (non-experimental) national survey carried out to measure household in

Intervention studies (I) are eligible only if pre-intervention data were available(I) and the comparator(C) of this meta-analysis was people who do not suffer from POI (age-matched). Condition being studied: Several studies have been conducted to show that POI affects the quality of life of patients, of which psychological and psychosocial factors cannot be ignored a

Abstract:
In this study, we ask whether the U-shaped relationship between life satisfactionand age is flatter for individuals who are partnered. An analysis of cross-sectionalEU-SILC data indicates that the decline in life satisfaction from the teens to thefifties is almost four times larger for non-partnered than for partnered individuals,whose life satisfaction essentially follows a slight downward trajectory with age.However, the same analysis applied to three panel datasets (BHPS, SOEP andHILDA) reveals a U-shape for both groups, albeit somewhat flatter for the partneredthan for the non-partnered in

Abstract:
Gas Technology Institute (GTI) and Edison Welding Institute (EWI) created both laboratory and infield girth weld samples to evaluate the effects of weld geometry and hydrogen off-gassing on the performance of protective coatings. Laboratory-made plate welds were used to tightly control geometric differences and in-field welds were created to mimic real-world welding conditions and hydrogen off-gassing rates. These welds were then coated and tested with accelerated corrosion techniques to evaluate the coatings' effectiveness. Simulated girth welds investigated geometric effects on the performan
