The improvement of previously described protocols for the regeneration shoots from ‘Canino’ mature seed hypocotyl slices has been accomplished. effects different factors such as part used, vacuum-infiltration, 2,4-Dichlorophenoxyacetic acid pulse, vacuum-infiltration and sonication on transient transformation were analyzed. When three obtained hypocotyls evaluated separately medium, highest per...

Metallic nanoparticles are important substances in medicine. These particles could be prepared by various ways including green synthesis. The production of silver plant extracts is widely used because their environmentally friendly properties. In this study, have been synthesized biological method and Apricot tree (Prunus armeniaca) leaf extract was as reducing agent. color change formation the...

In this work a complete problem for an unambiguous logspace class is presented. This is surprising since unambiguity is a `promise' or`semantic' concept. These usually lead to classes apparently without complete problems.

We d escribe new methods for the e s t imation of the b o u nds of the coeecients of proper divisors of integer polynomials in one v ariable. There exist classes of poly-nomials for which our estimates are better than those obtained using t he polynomial measure or the 2-weighted norm.

We consider the problem of derandomizing random walks in the Euclidean space R. We show that for k = 2, and in some cases in higher dimensions, such walks can be simulated in Logspace using only poly-logarithmically many truly random bits. As a corollary, we show that the random walk can be deterministically simulated in space O(logn √ log log n), where 1/n is the desired precision of the simul...

In 1957 W.M. Hirsch conjectured that every d-polytope with n facets has edge-diameter at most n ? d. Recently Holt and Klee constructed polytopes which meet this bound for a number of (d; n) pairs with d 13 and for all pairs (14; n). These constructions involve a judicious use of truncation, wedging, and blending on polytopes which already meet the Hirsch bound. In this paper we extend these te...

Bahçe ürünlerinde hasat sonrası kayıpların önlenmesinde bitkisel uçucu yağların da içerisinde yer aldığı kimyasallara alternatif uygulamalar giderek popüler hale gelmektedir. Bu çalışmada, hasattan önce uygulanan okaliptüs (Eucalyptus camaldulensis Dehnh), kekik (Origanum onites L.) ve kayısı çekirdeği (Prunus armeniaca yağlarının (2 mL L-1) ‘Rubygem’ çilek çeşidi meyvelerinin muhafaza süresi k...
