genetic diversity is a key component of ecosystems. the aim of the present study was to evaluate the genetic diversity of iranian native honeybee colonies (apis mellifera meda l.) located in the northern region. colonies from 24 locations have been analyzed using microsatellite markers. samples were collected from caspian sea southern area (north of iran). six microsatellite markers (a28, a29, ...

The nondestructive discrimination model based on near-infrared is usually established by detected spectra and chemometric methods. However, the inherent differences between instruments prevent from being used universally, calibration transfer often to solve these problems. Standard-sample requires additional standard samples build a mathematical mapping instruments. Thus, standard-free research...

Maintenance and inspection errors have been the primary cause of six percent of aircraft accidents and have contributed to an additional nine percent of the accidents from 1982 through 1993. What can maintenance organizations do to reduce these types of errors? This paper discusses the development and evaluation of a maintenance error investigation process--the Maintenance Brror Decision Aid (M...

The synthesis of mellophanic dianhydride (MEDA) from biosourced 1,2,3,4-benzene tetracarboxylic derivatives and its use as a chain extender for mechanically recycled PET (R-PET) an alternative to traditional oil-based pyromellitic (PMDA) is reported. rheological tests performed on the R-PET extruded with MEDA have shown similar results those obtained PMDA, dynamic mechanical thermal analysis (D...

Homozygosity of Sex Determination Locus and It’s Correlation with Population Honey Production Honeybee (Apis Mellifera Meda) Populations in West-Azerbaijan Kurdistan Provinces

Objectives: Royal jelly (RJ), a secretion of both the hypopharyngeal and mandibular glands of nurse workers, is believed to play a central role in honeybee queen development. Important component of royal jelly are proteins which form about 50% of the dry mass of RJ. Major royal jelly proteins (MRJPs) are the dominant proteinaceous component of royal jelly and constitute about 82-90% of total pr...

The Mars Environmental Dynamics Analyzer (MEDA) on board Perseverance includes first-of-its-kind sensors measuring the incident and reflected solar flux, downwelling atmospheric IR upwelling flux emitted by surface. We use these measurements for first 350 sols of 2020 mission (Ls ∼ 6°–174° in Martian Year 36) to determine surface radiative budget calculate broadband albedo (0.3–3 μm) as a funct...

By means of modified extended direct algebraic (MEDA) method the multiple exact complex solutions of some different kinds of nonlinear partial differential equations are presented and implemented in a computer algebraic system. New complex solutions for nonlinear equations such as one-dimensional Burgers, KDV-Burgers, coupled Burgers and twodimensional Burgers’ equations are obtained.

As is known, the Pareto set of a continuous multiobjective optimization problem with m objective functions is a piecewise continuous (m - 1)-dimensional manifold in the decision space under some mild conditions. However, how to utilize the regularity to design multiobjective optimization algorithms has become the research focus. In this paper, based on this regularity, a model-based multiobject...
