As formative research for the development of a suite of middle school life science video games, we are adapting microgenetic research methods [15] that use repeated, small-scale task-based sessions with participants to document how reasoning and understanding can develop and change in short periods of time. In this study, we are working with students between the ages of 9 and 12, examining the ...

Bite-like skin lesions on harbour porpoises (Phocoena phocoena) have been suspected to be caused by grey seals (Halichoerus grypus), and a few field observations have been reported. Bite-like skin lesions observed on stranded animals were characterized by two main components: large flaps of loose or missing skin and blubber with frayed edges and puncture lesions. Definitive demonstration of pre...

Population structure, growth, length-weight relationship and reproduction characteristics of leaping grey mullet (Liza saliens (Risso, 1810) were investigated in Beymelek Lagoon from February 2006 to January 2007.  During the study, a total of 1248 leaping grey mullet were captured by gill- and trammel nets of various mesh sizes. Male to female ratio for leaping grey mullet population in Beymel...

OBJECTIVES To assess whether having received grey packets containing treatment for gonorrhoea and chlamydia was associated with condom use among female sex workers (FSWs) in 5 districts of southern India covered by the Avahan programme where both periodic presumptive treatment (PPT) and syndromic management were used to control these sexually transmitted infections (STIs) among FSWs. SETTING ...

This study investigated the optimization of three welding parameters (wire feed speed, arc voltage, and shielding gas flow rate) for SS 304H by using Taguchi based Grey relational analysis. In this research work, pure argon was used as shielding gas. Numbers of trials were performed as per L16 (4xx3) orthogonal array design and the mechanical quality such ultimate tensile strength, microhardnes...

In the process of power transformer risk assessment, loss degree index is difficult to accurately quantify due influence uncertain factors, leading deviation judgment. A assessment method based on three-parameter interval grey number decision-making proposed. Firstly, fault probability quantified condition evaluation results. Secondly, considering uncertainty DG output and load, Nataf transform...

The totally positive algebraic integers of certain number fields have been shown to be the sums of four squares of integers from their respective fields. The case ofQð ffiffiffi 5 p Þ was demonstrated by Götzky and the cases of Qð ffiffiffi 2 p Þ and Qð ffiffiffi 3 p Þ were demonstrated by Cohn. In the latter situation, only those integers with even coefficient on the radical term could possibl...

In the recent paper [3] by Asai et al., the growth order of holomorphic functions on a nuclear space has been considered. For this purpose, certain classes of growth functions u are introduced and many properties of Legendre transform of such functions are investigated. In [4], applying Legendre transform of u under the conditions (U0), (U2) and (U3) (see §2), the Gel’fand triple [E ]u ⊂ (L) ⊂ ...

We describe a new approach to modelling the appearance of structures in grey-level images. We assume that both the shape and grey-levels of the structures can vary from one image to another, and that a number of example images are available for training. A 2-D image can be thought of as a surface in 3 dimensions, with the third dimension being the grey-level intensity at each image point. We ca...
