Point blank range

The minimum range for the 3.5 rocket is 15 feet, which is the distance required for the bore-riding safety to fly free and arm the rocket. The best point blank range is 15 feet to 100 feet. 

Right... As I turned the comer, I heard a pistol go off behind me like thunder. I hoped that the shot had been intended for me and not to put Vasco out of his misery, but firearms kick so much that he would not have been in much danger, even at point-blank range. 

This is a true story. I shot her seven times before she finally fell from the Cottonwood tree -- and yet she lived By then I was almost crazy with emotions I can t even identify. On the eighth shot she died, the beautiful head blown into pulp at point-blank range. Utter grief swept over me. I had committed the most unforgivable of sins. A line from Robinson Jeffers seared through my brain ... 

Falcon was a Culverin type artillery piece of about 16th century which, accdg to Dupuy Dupuy (Ref), weighed 800 lbs, had bore of 2.5 inches, length 6.0 ft and fired projectiles weighing 3.0 lbs. Its point blank or effective range was 400 yds and maximum range 2500 yds... 

For higher accuracy in the low polymer concentration range, two different methods were used. In the case of PAA, potentiometric titrations of solutions of PAA were performed with 0.01 N NaOH using a Brinkman model, Westbury, NY, automated titrator. Blank tests indicated no interfering species. Known amounts of PAA were used to prepare a calibration curve immediately after titration of the samples containing unknown amounts of polymer. The starting point of the titration was pH 4.0, and the end point was reached near pH 8. Total volumes of 75 or 100 cc were used for the titrations, and the ionic strength was controlled at 0.01 M NaCl. 

The most important point is the purpose of the future analyses. In which range do we expect the quantities to be measured Of comse there are technical limitations. For very low concentrations we have to ensure that the signal triggered by this content is significantly different from the signal of the blank. 

Standard solutions of sodium chloride (NaCl) and potassium chloride (KCl) in water were prepared and diluted appropriately to give a calibration curve across the working range across the range of the instrument (ca 0.05-1 mg/100 ml). The assay was then carried out by diluting the infusion until its concentration was close to that at the mid-point of the calibration series. Water is used as a blank. The following results were obtained ... 

Adjust the pH of the sample in the range 7 to 10. To a 100-mL sample, add 1 mL 30% H2Oz and stir. Add 1 mL of K2Cr04 indicator. Titrate the sample with standard AgN03 (0.0141 N) titrant to pink end point. Run a blank using distilled... 

Assay calibration involves the use of human serum samples fortified with CP-80,794 at 11 concentrations (six replicates per concentration) ranging from 0.05 to lOng/mL. In this particular case, due to a narrow linear dynamic range, two standard curves, ranging from 0.05 to lOng/mL, are constructed to provide the best accuracy. Serum blanks and an 11-point standard curve (two samples per concentration) are analyzed with each set of unknown samples. 

In the proposed assay, there was no interference in the measurement of the aequorin activity by biotinylated luciferase. The sensitivity of aequorin was 7.58xl0 0 mol/assay (blank + 3SD, Fig. 2, left), the calibration linearity of the assay ranged from 1.21 X lO mol/assay to 1.94 x lO mol/assay and the intra-assay coefficients of variation (CV) for 8 replicates with each standard point were from 1.0 to 3.2%. These results are similar to the results from the separate assay. 

Preparation of Standards and Curves In the absence of a true blank control matrix, standards can be prepared in a protein buffer at multiple (generally 9 11) concentrations for the initial test of assay range. For method validation and sample assay, 6 8 nonzero concentrations of standards plus anchor points should be used to define a curvilinear standard curve. If a commercial kit is to be used, it is preferred that the standards be prepared from a bulk reference material to assure the consistencies of the standard as well as adding enough standard points to properly define the regression model. Before replacing the kit standards with those prepared...
