This study describes and interprets the evolution of grain-size distribution of sediment yields generated in an experimental soil flume subjected to downstream and upstream moving rain storms. Results of laboratory experiments show that downstream moving storms cause more soil loss than do upstream moving storms. The pattern of sediment grain-size evolution in time during a runoff event exhibit...

Fischer plots are plots of accommodation (derived by calculating cumulative departure from mean cycle thickness) versus cycle number or stratigraphic distance (proxies for time), for cyclic carbonate platforms. Although many workers have derived programs to do this, there are currently no published, easily accessible programs that utilize Excel. In this paper, we present an Excel-based spreadsh...

[1] The estimation of catchment-averaged aquifer hydraulic conductivity values is usually performed through a base flow recession analysis. Relationships between the first time derivatives of the base flow and the base flow values themselves, derived for small and large values of time, are used for this purpose. However, in the derivation of the short-time equations, an initially fully saturate...

Venous limb gangrene (VLG) can occur in cancer patients, but the clinical picture and pathogenesis remain uncertain. We identified 10 patients with metastatic cancer (7 pathologically proven) who developed severe venous limb ischemia (phlegmasia/VLG) after initiating treatment of deep-vein thrombosis (DVT); in 8 patients, cancer was not known or suspected at presentation. The patients exhibited...

Local scour holes are erosional bed structures that related to different scientific disciplines in Earth science and hydraulic engineering. scouring at naturally placed boulders is ubiquitous, but many competing factors make it difficult isolate the effects of a given variable. This especially true for local natural instream obstacles exposed unsteady flow conditions course flood hydrograph exp...

Resumen. In recent years, there has been extensive use electromyographic signals (EMG ́s) as the primary inputs on algorithms used in control of smart prosthesis; at the same time, the use of classification algorithms to identify patterns in upper limb movements is rising . Some of the main challenges that exist in classification are; EMG's feature extraction and high complexity of algorithms th...

Dear Editor, Coverage of poorly vascularised diabetic wounds is an important rising surgical challenge. Failure leads to amputations and increased morbidity. Worldwide, a limb is lost to diabetes every 30 seconds. Diabetic prevalence in Singapore is 8.2% with 13.9% having vasculopathy, 28.8% stage 2 King’s Classifi cation and 700 diabetic amputations every year.1 We highlight how synergistic HB...

OBJECTIVES This study sought to analyze the effects of resistance training on functional performance, lower-limb loading distribution and balance in older women with total knee arthroplasty (TKA) and osteoarthritis (OA) in the contralateral knee. In addition, this older knee OA and TKA group (OKG) was compared to older (OG) and young women (YG) without musculoskeletal diseases who underwent the...
