To generate big responses of unemployment to productivity shocks in a business cycle context or to productivity changes in a welfare state context, researchers have reconfigured matching models in various ways, e.g., by elevating the utility of leisure, by making wages sticky, by assuming alternating-offer wage bargaining, by introducing fixed matching costs, and the costly acquisition of credi...

Ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) activation decreases under moderate heat stress. This decrease is caused by an impairment of activase function, which is exacerbated by faster rates of Rubisco deactivation at elevated temperatures. To determine if stromal oxidation causes inhibition of activase, transgenic Arabidopsis plants expressing suboptimal amounts of either the r...

This study was undertaken to determine how photosynthesis tolerates desiccation in an intertidal alga Fucus vesiculosus L. and a terrestrial sunflower Helianthus annuus L. Photosynthetic O2 evolution generally was inhibited at low water potentials (psiw) but more in sunflower leaves than in Fucus fronds at the same psiw. As psiw decreased, less carbon accumulated in an organic carbon store in F...

A 39-year-old woman was admitted to our hospital with symptoms of general fatigue, nausea, and vomiting that appeared three months after she stopped seven years of medroxyprogesterone acetate (MPA) medication for endometrial stromal sarcoma. Laboratory tests demonstrated moderate hypercalcemia. Several tests demonstrated that she was suffering from adrenal insufficiency. Glucocorticoid suppleme...

The effect of moderate pressure at subzero temperature on natural microflora of minced cod, salmon, pork and beef meat was studied. Pressure of 193 MPa at –20 °C caused the reduction of total bacterial count in pork and beef meat by 1.1 and 0.6 log cycles, respectively, and by about 1.5 log cycles in fish meat. Under these conditions the psychrophilic and psychrotrophic bacteria were below the ...

 Net photosynthesis rate (Pn), stomatal conductance (gs) and transpiration rate (E) of anise hyssop were measured during the four cloudless days, in reference to diurnal fluctuations of leaf temperature (Tleaf), leaf vapor pressure deficit (VPD leaf) and photosynthetic photon flux density (PPFD) in well watered (WW), stressed (S) and recovered (R) plants. An analysis of measured data showed tha...

We studied hydraulic traits of young plants of the Mediterranean cedar species Cedrus atlantica (Endl.) G. Manetti ex Carrière (Luberon, France), C. brevifolia (Hook. f.) Henry (Cyprus), C. libani A. Rich (Hadeth El Jebbe, Lebanon) and C. libani (Armut Alani, Turkey). With an optimum water supply, no major differences were observed among species or provenances in either stem hydraulic conductiv...

Peanut, an important oilseed crop, frequently encounters drought stress (DS) during its life cycle. In this study, four previously developed mtlD transgenic (T) peanut lines were used for detailed characterization under DS, at the reproductive stage using lysimeter system under controlled greenhouse conditions. In dry-down experiments, T lines maintained better photosynthetic machinery, such as...
