The cytological features including chromosome numbers and detailed measurements of 46 populations ten Achillea species ( A. aleppica, bibersteinii, eriophora, filipendula, millefolium, nobilis, pachycephala, tenuifolia, vermicularis, wilhelmsii ) were reported from Iran. Sample plants seeds collected diff erent geographical regions Total length, long/ short arm ratio, centromere index, total fo...

Reasoning with domains containing continuous numeric change remains an open challenge in planning. In this paper, we discuss how an established temporal planner, CRIKEY3, can be adapted to plan in domains containing linear continuous numeric change. In particular, we discuss how an LP can be used to scheudule action choices, and how the LPRPG heuristic (hitherto for non-temporal planning) can b...

The Zarankiewicz number z(b; s) is the maximum size of a subgraph of Kb,b which does not contain Ks,s as a subgraph. The two-color bipartite Ramsey number b(s, t) is the smallest integer b such that any coloring of the edges of Kb,b with two colors contains a Ks,s in the rst color or a Kt,t in the second color.In this work, we design and exploit a computational method for bounding and computing...

Chromosome conformation capture (3C) techniques are crucial to understanding tissue-specific regulation of gene expression, but current methods generally require large numbers of cells. This hampers the investigation of chromatin architecture in rare cell populations. We present a new low-input Capture-C approach that can generate high-quality 3C interaction profiles from 10 000-20 000 cells, d...

Background: Spontaneous abortion (SAb) is the most common complication of early pregnancy. Numerous risk factors are associated with an increased risk of pregnancy loss such as: Maternally age, previous spontaneous abortion, prolonged ovulation to implantation, Gravidity, Interval Prolonged time to pregnancy, Balanced chromosomal translocations and Genetic disorders. The aim of this study was t...

Background: Most of our current understanding of the biological effects of exposure to ionising radiation is based on conventional cytogenetic techniques, which enable us to determine the relationship between chromosomal aberration and dose received by radiation workers. However, conventional techniques have numerous limitations and chromosomal aberrations can be easily missed. Since FISH plays...

in this paper, a novel method for ranking of fuzzy numbers are proposed. in this method, decision maker is defined based on the center of mass at some cuts of a pair of fuzzy numbers in discreet version and center of mass on all of cuts of a pair of fuzzy numbers in continuous version. our method can rank more than two fuzzy numbers simultaneously. also, some properties of methods are described...

this research was an attempt to study reasons for creation of some of the important and sacred numbers and their reflection in architectural and urban spaces. this subject matter is important because significant and sacred numbers were used in design and construction of a number of historical spaces. the research objective was to discover some of the reasons for formation of important and sacre...

objective(s) the main objective of this study was to investigate the status of chromosome stability in 3 human-mouse hybridoma cell lines over a period of time in various passages. materials and methods metaphase spreads from 3 human-mouse cell lines (hf2x653, spmo-4 and f3b6) that had been cultured in 4 successive passages, from 1 to 4 weeks, were prepared and analyzed. metaphase chromosomes s...
