A Growth Cycle
نویسنده
چکیده
Presented here is a starkly schematized and hence quite unrealistic model of cycles in growth rates. This type of formulation now seems to me to have better prospects than the more usual treatment of growth theory or of cycle theory, separately or in combination. Many of the bits of reasoning are common to both, but in the present paper they are put together in a different way. The following assumptions are made for convenience: (1) steady technical progress (disembodied); (2) steady growth in the labour force; (3) only two factors of production, labour and ‘capital’ (plant and equipment), both homogeneous and non-specific; (4) all quantities real and net;

CYTOKINE AND GROWTH FACTOR MODULATION OF CELL CYCLE EVENTS IN HUMAN MELANOMA CELL LINES
Cytokines influence cell cycle events, which in some but not all instances can be associated with melanoma progression. Analysis of the G0/G 1 and S phase fractions of the cell cycle was used to assay the proliferative or inhibitory activity of cytokines against ten human melanoma cell lines, including pairs of cell lines derived from primary and metastatic tissue of individual patients. Cy...
متن کاملPredicting Low Cycle Fatigue Life through Simulation of Crack in Cover Plate Welded Beam to Column Connections
This paper presents a low cycle fatigue life curve by simulating a crack in a cover plate welded moment connection. Initiation of ductile fracture in steel is controlled by growth and coalescence of micro-voids. This research used a numerical method using finite element modeling and simulation of ductile crack initiation by a micromechanical model. Therefore, a finite element model of a cover p...
متن کاملUltra-Low Cycle Fatigue Fracture Life of a Type of Buckling Restrained Brace
Buckling restrained braced frames (BRBFs) for seismic load resistance have been widely used in recent years. One of the key requirements for a buckling restrained brace is to sustain large plastic deformations under severe ground motions. The core of a buckling restrained brace is prone to fatigue fracture under cyclic loading. The earthquake induced fracture type of the core plate in a bucklin...
متن کاملEconomically optimal cutting cycle in a beech forest, Iranian Caspian Forests
The aim of this study was to determine the optimal cutting cycle in an uneven-aged beech forest in the North of Iran. First of all, a logistic growth model was determined for an uneven aged forest. Then, the stumpage price was predicted via an autoregressive model. The average stumpage price of beech was derived from actual timber, round wood, fire and pulpwood prices at road side minus the var...

متن کاملEvaluation of some changes in biochemical parameters of Iranian lily (Lilium ledebourii var. Kelardasht Salehi1) bulbs during a growth and development cycle
Understanding the relationships between biochemical contents and morpho-phenological aspects of a plant during life cycle would be helpful for doing precise agricultural practices through its cultivation. In the present study, various biochemical parameters were evaluated in relation to bulb storage, shoot growth and florogenesis in Iranian lily (Lilium ledebourii var. Kelardasht Salehi1). Ten ...
