A modification of the classical procedure of fluctuation analysis is used to measure the waveform, w(t), mean amplitude, (h), and mean rate of occurrence, (r), of miniature endplate potentials (MEPPs) at frog cutaneous pectoris neuromuscular junctions treated with black widow spider venom (BWSV) . MEPP parameters are determined from the power spectrum of the fluctuating potential and the second...

Radio morphology data have been collected for a sample of radio galaxies from the Revised 3rd Cambridge (3CR) Catalog in the redshift range 0.15 < z < 0.65. Radio structure parameters including largest physical size, projected bending angle (β), lobe length asymmetry (Q) and hot spot placement (Fanaroff-Riley ratio) have been measured from the highest quality radio maps available. Combined with...

STUDY DESIGN Prospective randomized comparison of 2 rehabilitation programs. OBJECTIVES The objectives of this study were to compare the effectiveness of 2 rehabilitation programs for acute hamstring strain by evaluating time needed to return to sports and reinjury rate during the first 2 weeks and the first year after return to sport. A third objective was to investigate the relationship bet...

Flaminio and Montagna (2008) enlarged the language of MV-algebras by a unary operation σ, called internal state or a state operator, equationally defined so as to preserve the basic properties of a state in its usual meaning. The resulting class of MV-algebras is called state MV-algebras. Jenča (2007) and Vetterlein (2008), using different approaches, represented MV-algebras through the quotien...

OBJECTIVE To examine the role of physical activity, inactivity, and dietary patterns on annual weight changes among preadolescents and adolescents, taking growth and development into account. STUDY DESIGN We studied a cohort of 6149 girls and 4620 boys from all over the United States who were 9 to 14 years old in 1996. All returned questionnaires in the fall of 1996 and a year later in 1997. ...

We study the photometric and spectral properties of 39320 early-type galaxies within the Sloan Digital Sky Survey (SDSS), as a function of both local environment and redshift. The distance to the nearest cluster of galaxies (scaled by the virial radius of the cluster) and the distance to the 10 nearest luminous neighbor (Mr < −21.5) were used to define two extremes in environment. The propertie...

The diagnosis of primary hyperoxaluria in young children is hampered by the lack of a reliable reference range for urinary oxalate excretion, especially in infants. We present data on urinary oxalate and glycolate excretion in 137 normal children, on the plasma oxalate concentration in 33 normal children and 53 with chronic renal failure, and on amniotic fluid oxalate concentration in 63 uncomp...

وجود تغییرات مکانی در خصوصیات خاک امری طبیعی می باشد و شناخت این تغییرات به ویژه در اراضی کشاورزی جهت برنامه ریزی دقیق و مدیریت امری اجتناب ناپذیر است. مدیریت صحیح عملیات کشاورزی و حفظ مواد آلی خاک، از جمله عوامل مهم در کشاورزی پایدار می باشند. اهداف این پژوهش، شامل بررسی تاثیر ویژگی های توپوگرافی از جمله جهت شیب با استفاده از dem بر تغییرپذیری کربن آلی خاک و تهیه نقشه رقومی کربن آلی خاک با است...
