OBJECTIVE An accurate assessment of the nutritional status of an infant at birth is very important, since it provides information on early identification of pathological events related to intrauterine growth acceleration or retardation. Anthropometric ratios such as weight/length and mid-arm circumference/head circumference may be used as alternative tools for this purpose. The main objective o...

Objective: In our study, it was aimed to obtain linear regression formulas for estimating stature from upper arm length values of young adult female and male individuals examine the effect right-left side asymmetry on formulas. Materials & Methods: The study carried out 70 healthy volunteers (35 males, 35 females) aged 18-36 years. Upper obtained by measuring distance acromion olecranon...

Karyological characteristics of bighead goby (Neogobius kessleri) in the Caspian Sea were studied by examining 30 metaphase chromosome spreads from the kidney tissue of 10 specimens. The chromosome number of this species was found 2n=46 and the arm number as NF=46. The prepared karyotype of this species consisted of 23 pairs acro-telocentric (a-t) chromosomes. The chromosomal formula can be sta...

A clearly definable upper tolerance limit for chromosome arm length has been found. As a rule we postulate that, for normal development of an organism, the longest chromosome arm must not exceed half of the average length of the spindle axis at telophase. Above this length, fertility and viability of the carrier individuals become severely impaired due to increasingly incomplete separation of t...

Effects of salinity on fertilization, embryonic stage, and early larval development and growth performances of short-spined white sea urchin, Salmacis sphaeroides were conducted under a controlled laboratory condition. The experiment was carried out with seven salinity treatments (15, 20, 25, 30, 35, 40 and 45 PSU), each of which was triplicated. Significantly highest fertilization success was ...

In this paper we present our developed expandable sliding arm which enables a small sized mobile robot to push and pull objects. The mobile robot arm can manipulate objects such as elevator buttons, light switches and mailbox drawers. The expandable arm has 3 degrees of freedom; a rotary degree of freedom at the base, a stretching degree of freedom and a rotary degree of freedom at the end-effe...

The LIGO (Laser interferometer Gravitational-wave Observatory) detector [1] is a complex Fabry-Perot/Michelson interferometer designed to detect gravitational waves (GW) from astrophysical sources (Fig. 1). When a GW strikes the detector, the underlying space will be extended in one direction and contracted in the orthogonal direction. The LIGO detector is designed to detect this space-strain a...

Myosins are actin-based motors that are generally believed to move by amplifying small structural changes in the core motor domain via a lever arm rotation of the light chain binding domain. However, the lack of a quantitative agreement between observed step sizes and the length of the proposed lever arms from different myosins challenges this view. We analyzed the step size of rat myosin 1d (M...

We reported the optical properties of hybrid Mach-Zehnder Interferometer (MZI) designed by silicon waveguide covered with graphene material in single-atomic layer thickness. Graphene was applied to the specific area of MZI arm in certain length. The upper arm was set as the sensing region and another arm plays an important key as the reference signal. The sensor sensitivity has determined mathe...
