This experiment was conducted during 2021-2022 in the Duhok University nursery, Iraqi Kurdistan region, to study effects of three different Apple cultivars (Super red, Scarlet and Royal caka), budding dates (28th August,18th September 8th October 2021) levels balanced fertilizer N20%, P20% K20 %; (0 g, 2g 4g. l-1) on successful percentage some vegetative growth characteristics apple transplants...

The purpose of this study was to examine: 1) whether caffeine in the fertilization medium under mineral oil is essential for bovine in vitro fertilization by fully capacitated spermatozoa, 2) the minimum concentration of caffeine that shows an adverse effect on the motility of preincubated spermatozoa. Cumulus-oocyte complexes with heterogeneous-appearing ooplasm were matured in in vitro cultur...

—In this paper, a clustering algorithm based on the cooperative transmission technology is proposed with respect to uneven energy consumption in large scope wireless sensor network. In this algorithm, to ensure the even distribution of the cluster head nodes in large scope wireless sensor network which has even clusters, the cooperative transmission technology is applied in data transmission a...

We prove a geometric version of the graph separator theorem for the unit disk intersection graph: for any set of n unit disks in the plane there exists a line ` such that ` intersects at most O( √ (m+ n) logn) disks and each of the halfplanes determined by ` contains at most 2n/3 unit disks from the set, where m is the number of intersecting pairs of disks. We also show that an axis-parallel li...

By analyzing the granted patents distribution of the energy-saving and environmental protection industry in China from 2008 to 2013, the conclusion can be reached: firstly, technological innovations of the energy-saving industry are focused on the environmentally air-conditioning and heat pump technical field, and technological innovations of the resources recycling industry is mainly concentra...

Experimental observation of Majorana fermion matter gives a new impetus to the understanding of the Lorentz symmetry and its extension, the geometrical properties of the ambient space-time structure, matter–antimatter symmetry and some new ways to understand the baryo–genesis problem in cosmology. Based on the primordial Majorana fermion matter assumption, we discuss a possibility to solve the ...

A long-running issue in scorecard construction in retail banking is how to handle dramatically unbalanced class sizes. This is important because, in many applications, the class sizes are very different. We describe the impact ignoring such imbalance can have and review the various strategies which have been proposed for tackling it, embedding them in a common theoretical framework. We then des...

In vitro fertilization (IVF) is a process by which an egg is fertilised by sperm outside the body: in vitro . The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from the woman's ovaries and letting sperm fertilise them in a liquid in a laboratory. The fertilised egg (zygote) is cultured for 2–6 days in a growth medium and is then i...

Distance-balanced graphs are introduced as graphs in which every edge uv has the following property: the number of vertices closer to u than to v is equal to the number of vertices closer to v than to u. Basic properties of these graphs are obtained. In this paper, we study the conditions under which some graph operations produce a distance-balanced graph.
