We studied relationships between diurnal patterns of stem water potential (PsiSTEM) and stem extension growth of the same scion cultivar growing on three rootstocks with differing size-controlling potentials. The peach trees (Prunus persica (L.) Batsch) used in this field experiment consisted of an early-maturing freestone cultivar, 'Flavorcrest,' grafted onto three different rootstocks: Nemagu...

OBJECTIVE To determine if the combined isometric contractions of knee extension/hip adduction and knee extension/hip abduction will elicit a different quadriceps and gluteus medius electromyographic (EMG) pattern as compared to isometric contraction of a uniplanar knee extension exercise. METHODS Eight healthy young adult volunteers without history of knee or quadriceps injury participated. S...

BACKGROUND Back extension exercises are often used in the rehabilitation of low back pain. However, at present it is not clear how the posterior muscles are recruited during different types of extension exercises. Therefore, the present study will evaluate the myoelectric activity of thoracic, lumbar and hip extensor muscles during different extension exercises in healthy persons. Based on thes...

The limited audio bandwidth of narrowband telephone speech degrades the speech quality. This paper proposes a method that extends the bandwidth of telephone speech to the frequency range 0–300 Hz. The lowest harmonics of voiced speech are generated using sinusoidal synthesis. The energy in the extension band is estimated from spectral features using a Gaussian mixture model. The amplitudes and ...

We consider the planar unit disk D as reference configuration and a Jordan domain Y deformed configuration, study problem of extending given boundary homeomorphism ?:?D?onto?Y Sobolev complex plane. Investigating such variant classical Jordan-Schönflies theorem is motivated by well-posedness related pure displacement variational questions in theory Nonlinear Elasticity (NE) Geometric Function T...

Knee extension is always performed with coordinated contractions of multiple quadriceps muscle components; however, how the load is shared among them under normal and pathological conditions is unclear. We hypothesized that: the absolute moment generated by each quadriceps component increases with the total knee extension moment; the relative contribution and its dependence on the total knee ex...

There are many representations of the Catalan numbers. In this article, we will examine the ballot problem and extend it beyond the standard p-Catalan extension to a left weighted extension. This extension reduces naturally to the p-Catalan numbers (including the standard 2-Catalan numbers). We will then give a variety of examples of the extension for other representations of the Catalan number...

there is undoubtedly general agreement that the efficiency of educational investments should he maximized through the managerial process as far as possible. agricultural extension is one of the crucial tasks in developing agricultural societies calling for considerable consumption of intellectual investment. the management of agricultural extension projects (aeps) however, needs careful pla...

Background: The amount of anterior tibial translation during rehabilitation exercises is a key factor in organizing exercise regimen after anterior cruciate ligament injury. Excessive anterior tibial translation could increase the magnitude of tension imposed on injured and reconstructed anterior cruciate ligament knees. Forward lunge and open-kinetic knee extension exercises are commonly used ...
