Mating Performance and Singlehood Across 14 Nations.

Adult individuals frequently face difficulties in attracting and keeping mates, which is an important driver of singlehood. In the current research, we investigated the mating performance (i.e.

On the relationship between valence and arousal in samples across the globe.

Affect is involved in many psychological phenomena, but a descriptive structure, long sought, has been elusive. Valence and arousal are fundamental, and a key question-the focus of the present study-is the relationship between them. Valence is sometimes thought to be independent of arousal, but, in some studies (representing too few societies in the world) arousal was found to vary with valence.

Domains of Everyday Creativity and Personal Values.

We examined the applicability of the hybrid model of creativity, which specifies distinct domains that all express an underlying general creativity factor, in data from representative samples from Central Russia and the North Caucasus ( = 2,046). Using multigroup confirmatory analysis, Study 1 supported the invariance of a model with the six unifactorial domains (i.e.

[A New Enzyme Preparation with High Penicillopepsin Activity Based on the Producer Strain Penicillium canescens].

The producer of fungal penicillopepsin, an aspartate protease, has been created by genetic engineering. The biochemical and physicochemical properties of the penicillopepsin enzyme preparation obtained from the culture liquid of the producer were studied. Properties of the new enzyme preparation and the commercially available aspergillopepsin were compared.

[Novel Enzyme Preparations with High Pectinase and Hemicellulase Activity Based on Penicillium canescens Strains].

Recombinant strains of Penicillium canescens producing homologous pectin lyase A and heterologous endo- 1,5-α-arabinase A and endo- 1,4-α-polygalacturonase, as well as enzymes of the host strain (α-L-arabinofuranosidases, xylanases, and others), were obtained by genetic engineering. The enzyme preparations (EPs) obtained from the cultural medium of recombinant P. canescens strains efficiently hydrolyzed raw plant material with a high content of pectin compounds.
