Ladder inclined angle is a critical factor that could lead to a slip at the base of portable straight ladders, a major cause of falls from heights. Despite several methods established to help workers achieve the recommended 75.5° angle for ladder set-up, it remains unclear if these methods are used in practice. This study explored ladder set-up behaviours in a field environment. Professional in...
To the Editor: Almost every report on circulating DNA identifies apoptosis or necrosis or both as the main source of free circulating DNA in serum and plasma. A hallmark of apoptosis is DNA degradation, in which chromo-somal DNA is 1st cleaved into large fragments (50 –300 kb) and subsequently into multiples of nucleoso-mal units (180 –200 bp) (1). This ladder pattern is also visible after elec...
In an extensive analysis, using a range of restriction endonucleases, HinfI and TaqI were found to differentiate satellites I, II and III & IV. Satellite I is resistant to digestion by TaqI, but is cleaved by HinfI to yield three major fragments of approximate size 770, 850 and 950bp, associated in a single length of DNA. The 770bp fragment contains recognition sites for a number of other enzym...
A ladder lottery, known as the “Amidakuji” in Japan, is a common way to choose an assignment randomly. Formally, a ladder lottery of a permutation π = (p1, p2, . . . , pn) is a network with n vertical lines (lines for short) and many horizontal lines (bars for short) as follows (see Fig. 1). The i-th line from the left is called line i. The top ends of the n lines correspond to π. The bottom en...
We designed a protein ladder (hereafter referred to as "Mega-tag") that contains 14 of the most commonly used epitope tags fused to molecular weight markers. The Mega-tag ladder can be simultaneously visualized when anti-tag antibodies are used to detect epitope-tagged recombinant proteins in Western blots. The logarithm of molecular weights and relative mobility of the Mega-tag protein ladder ...
After 20 years of a static clinical ladder program at our institution, the clinical ladder program was completely redesigned using a staff nurse-led shared governance structure to re-envision the program as an innovative, staff leadership model to meet our organizational nursing mission and vision strategic plans around retention and professional development. The literature demonstrated a lack ...
C = ladder network stage capacitance E = difference operator L = ladder network stage inductance ‘ = number of ladder network stages m = voltage measurement node n = ladder network node identifier, 0 n ‘ Rt = termination resistance s = Laplace variable V t = transmission line driving signal ~ Vn = Laplace transform of the voltage at any node n x = length of transmission line min = smallest wave...
Absrracr-The low sensitivity property of lossless discrete integrator (LDI) low-pass ladder filters is shown to be preserved in lossless discrete differentiator (LDD) high-pass ladder filters 111. The exact design method for LDI ladder filters given in [Z] is further developed by introducing a set of closed-form design formulas for digital ah-pole Chebyshev transfer functions. A new technique f...
زمینه و هدف: تعیین هویت اجساد مجهول الهویه از مسایل مهم در پزشکی قانونی است. امروزه استفاده از dna typing از اصلی ترین روش های تعیین هویت محسوب می شودکه معمولاً dna مورد نیاز از بافت های مختلف از قبیل خون، عضله، کبد و یا طحال استخراج می گردد. در اجسادی که چندین روز تا چند ماه از زمان مرگ آنها گذشته باشد، فساد جسد باعث از بین رفتن بافت های نرم می شود و در نتیجه ملکول dna توسط آندونوکلئازها تجزیه ...
