Neanurid collembola 침샘의 형태 및 세포학적 비교
이병훈 한국유전학회 1985 Genes & Genomics Vol.7 No.4
Salivary glands from eleven species of Neanuridae (Collembola) varied in morphology with distinct generic differences. Plotting a range diagram of the numbers and sizes of the cell nuclei revealed four separate groups, possibly suggesting three strategies controlling salivary gland growth, 1) cellular multiplication, 2) cell volume increase, or 3) a combination of the two. Cellular multiplication may assure accentuated salivary function in some advanced form like Crossodonthina spp. in the present study as a potential alternative to ontogenetic lateral DNA increase observed in dipteran groups and most Neanurid Collembola with giant chromosomes.

This paper presents a systematic formulation for the kinematic and dynamic analysis of flexible multibody systems. The system equations of motion are derived in terms of relative and elastic coordinates using velocity transformation technique. The position transformation equations that relate the relative and elastic coordinates to the Cartesian coordinates for the two contiguous flexible bodies are derived. The velocity transformation matrix is derived systematically corresponding to the type of kinematic joints connecting the bodies and system path matrix. This matrix is employed to represent the equations of motion in relative coordinate space. Two examples are taken to test the method developed here.

$Cu_2ZnSn(S,Se)_4(CZTSSe)$ thin film solar cells areone of the most promising candidates for photovoltaic devices due to their earth-abundant composition, high absorption coefficient and appropriate band gap. The sputtering process is the main challenge to achieving high efficiency of CZTSSe solar cells for industrialization. In this study, we fabricated CZTSSe absorbers on Mo coated soda lime glass using different pressures during the annealing process. As an environmental strategy, the annealing process is performed with S and Se powder, without any toxic $H_2Se$ and/or $H_2S$ gases. Because CZTSSe thin films have a very narrow stable phase region, it is important to control the condition of the annealing process to achieve high efficiency of the solar cell. To identify the effect of process pressure during the sulfo-selenization, we experiment with varying initial pressure from 600 Torr to 800 Torr. We fabricate a CZTSSe thin film solar cell with 8.24 % efficiency, with 435 mV for open circuit voltage($V_{OC}$) and $36.98mA/cm^2$ for short circuit current density($J_{SC}$), under a highest process pressure of 800 Torr.
