ESTIMATING RAINFALL EROSIVITY BY DROP SIZE DISTRIBUTIONS

Water soil erosion is a process of detachment and transport of soil particles due to rainfall and runoff and it is the main cause of the modeling of extended portions of the earth's surface. The acceleration of the process through anthropogenic perturbation has severe impacts on soil and environmental quality. Soil erosion above a certain level will reduce soil productivity over the long haul. It exposes subsoil, which has often poor qualities for crop establishment and growth, and it can lead to stand loss by sediment deposition. A fundamental property of rainfall for understanding how it is made up is the raindrop size distribution (DSD). The knowledge of the raindrop size distribution at…

Performance Dissimilarities in European Union Manufacturing: The Effect of Ownership and Technological Intensity

2021

Our paper addresses the relevance of a set of continuous and categorical variables that describe industry characteristics to differences in performance between foreign versus locally owned companies in industries with dissimilar levels of technological intensity. Including data on manufacturing sector performance from 20 European Union member countries and covering the 2009–2016 period, we used the random forests methodology to identify the best predictors of EU manufacturing industries’ a priori classification based on two main attributes: ownership (foreign versus local) and technological intensity. We found that EU foreign-owned businesses dominate locally owned ones in terms of size, wh…

Physical exercise increases adult hippocampal neurogenesis in male rats provided it is aerobic and sustained

2016

Aerobic exercise, such as running, has positive effects on brain structure and function, such as adult hippocampal neurogenesis (AHN) and learning. Whether high-intensity interval training (HIT), referring to alternating short bouts of very intense anaerobic exercise with recovery periods, or anaerobic resistance training (RT) has similar effects on AHN is unclear. In addition, individual genetic variation in the overall response to physical exercise is likely to play a part in the effects of exercise on AHN but is less well studied. Recently, we developed polygenic rat models that gain differentially for running capacity in response to aerobic treadmill training. Here, we subjected these l…

Environmental factors influencing the distribution and prevalence of Schistosoma haematobium in school attenders of ILembe and uThungulu Health Distr…

2017

Schistosoma haematobium infection is reported to facilitate the development of urogenital diseases. Its symptoms include haematuria, dysuria and tiredness, and it may cause cognitive decline in children. The prevalence of S. haematobium infection needs to be known in endemic areas and a mass treatment programme against the disease implemented. The aim of this study was to investigate the prevalence and intensity of S. haematobium infection in ILembe and uThungulu health districts, using the major symptom, haematuria, as an indicator. A total of 6 265 urine samples, from 96 rural schools, was collected for analysis using dipsticks. The prevalence of haematuria in the ILembe health district w…

A 10-Week Block of Combined High-Intensity Endurance and Strength Training Produced Similar Changes in Dynamic Strength, Body Composition, and Serum …

2020

Purpose: To examine the potential sex differences in adaptations to combined endurance and strength training in recreationally endurance trained (eumenorrheic) women (n = 9) and men (n = 10). Methods: Isometric (ISOMmax) and dynamic bilateral leg press (1RM), countermovement jump (CMJ), running performance (3,000 m time trial), lean mass and body fat % (LEAN and FAT% determined by dual X-ray absorptiometry) as well as serum testosterone and cortisol (TES and COR, respectively, measured using hormone-specific immunoassay kits) were examined before a control period and pre, mid, and post a supervised 10-week combined high-intensity interval endurance training (4 × 4 min intervals and 3 × 3 × …

Space-Time Forecasting of Seismic Events in Chile

2017

The aim of this work is to study the seismicity in Chile using the ETAS (epidemic type aftershock sequences) space‐time approach. The proposed ETAS model is estimated using a semi‐parametric technique taking into account the parametric and nonparametric components corresponding to the triggered and background seismicity, respectively. The model is then used to predict the temporal and spatial intensity of events for some areas of Chile where recent large earthquakes (with magnitude greater than 8.0 M) occurred.

Influence of the Resin Layer Thickness at the Interface of Hybrid Metal-composite Co-cured Joints

2011

As discussed in literature, the accurate analysis of the modern co-cured joints between composite materials or between a metal and a composite material (hybrid joints) is complicated by the influence of the interface resin layer on the interface singular stress field. In such joints, in fact, there is not a proper adhesive layer and the thickness of the resin layer, that plays the role of the adhesive, is not constant due to the presence of the reinforcing fibers in the composite adherent. For this reason several authors assume that a generic co-cured joint can not be studied as a simple bi-material joint, without considering the particular characteristics of the actual resin layer. This pr…

Sāpju intensitāte atkarībā no subjektīvā laika

2018

Darba mērķis bija noskaidrot, vai maldinoša laika reprezentācija, ietekmē sāpju intensitātes uztveri. Darba hipotēze bija, vai manipulējot ar subjektīvā laika uztveri jeb rādot maldinošu laika reprezentāciju, samazināsies sāpju intensitāte. Pirmās eksperimentālās grupas rādītāji ir M = 5,15, SD = 1,24, šie rādītāji salīdzinājumā ar otro eksperimentālo grupu ir augstāki M = 4,18, SD = 1,19, darba hipotēze tika apstiprināta. Kopā pētījumā bija 58 dalībnieki, 35 vīrieši, vecums M = 22,40, SD = 2,49 un 23 sievietes, vecums M = 24,52, SD = 4,11. Bija dubultaklais pētījuma dizains ar divām eksperimentālām grupām, pirmā eksperimentālā grupa (n = 28) un otrā eksperimentālā grupa (n = 30). Darba aut…
