Crude wild pear lipoxygenase (LOX) from ripe Kurdistan wild pears was used in this study. Extracted crude LOX was assayed spectrophotometrically for raw, ripe wild pear lipoxygenase and after 7-day storage. The effects of different buffers and pHs, substrate preparations, temperature, inhibitors and metal ions on LOX activity were evaluated at three conditions. The enzyme was most active with H...

some physical properties and chemical compositions of two cultivars (semsouri and shahabadi) of cantaloupe studied during four different stages of maturity from fruit set to completely ripe. the physical properties investigated were the geometric mean diameter (gmd), specific gravity (sg), mean firmness (mf), rind, seed (%) and flesh (%). the chemical compositions were brix, titrable acidity (t...

Archaeobotanical and genetic analysis of modern plant materials are drawing a complex scenario for the origins cereal agriculture in Levant. This paper presents an improved method study early farming harvesting systems based on texture gloss observed sickle blades through confocal microscopy. Using this method, we identify different activities (unripe/semi-ripe/ripe reaping reed grass cutting) ...

We present techniques for detecting unauthorized DNS root servers in the Internet using primarily endpoint-based measurements from RIPE Atlas, supplemented with BGP routing announcements from RouteViews and RIPE RIS. The first approach analyzes the latency to the root server and the second approach looks for route hijacks. We demonstrate the importance and validity of these techniques by measur...

The purpose of this study was to determine how potential lexical ambiguity produced by place assimilation is resolved. Four cross-modal form priming experiments using primes in sentential contexts were performed. In the first 2, prime items had underlyingly coronal offsets (e.g., right) with assimilated noncoronal place. The primes were judged to be perceptually ambiguous (between right and rip...

Propionic acid (10(-3)m) increases ethylene production by about 30 to 60% in tissue from green and half-ripe tomatoes (Lycopersicon esculentum Mill. var. Homestead) but does not increase ethylene production in tissue from ripe fruit. Stimulation is not due to the conversion of propionic acid to ethylene but appears to be secondary in nature and to operate on the endogenous ethylene-forming syst...
