Field observations were made of flowering, fruit set, and fruitlet drop on the self sterile pear variety Packham's Triumph. All flowers were hand pollinated on the day of anthesis so that lack of pollination was not a limiting factor. In general, the flowers opened in order from the lowest to the terminal flower in the truss in approximate daily succession. During the first three weeks after petal fall, fruitlet drop occurred mainly from the higher axillary and terminal positions in the truss, and during the next three weeks there was some thinning out of fruitlets in the lower axillary positions. At harvest, most of the remaining fruit occurred at the second and particularly the third positions from the base of the truss. Fruit set was directly related to the number of flowers in the truss.

The flowering phenology, blooming time and inter-fertility relations of 63 European plum varieties has been studied at growing sites with different ecological conditions during a 10 year long period. The purpose was to develop a system of variety combinations which approaches an optimum in fertility as long as inter-fertility relations will cease to be a limiting factor of yield. According to their blooming time, varieties are assigned to 5 groups: very early, early, medium, late and very late. As for their fertility relations, four groups are formed: self-sterile (0%), partially self-fertile (0.1 to 10 %), self-fertile (10.1 to 20 %) and highly self-fertile (more than 20 % fruit set with self pollination). The four categories of fruit set at free pollination are also relevant to the grower: low (less than 10 %), medium (10 to 20 %), high (20 to 40 %) and very high (more than 40 % fruit set). By artificial cross pollination, one combination Cacanska najbolja x Stanley proved to be mutually inter-incompatible. Blocks planted to a single self-sterile variety flanking a pollinizer variety proved the spacial distribution of the pollen. The reduction in fruit set was already apparent in the second row away from the pollinizer trees. In a large plantation, without bee hives, relatively low yield was stated on self-sterile trees even close to the pollinizer. In the case of self-sterile and partially self-fertile varieties, a combination of three varieties is recommended. The blooming period of the pollinizer variety should overlap the period of the self-sterile variety at least by 70 %, and the distance should not exceed 15 to 20 meters. Association of self-fertile varieties may also enhance the productivity of the trees. In that case an overlap of 50 % in blooming time and a maximum distance between the varieties of 30 to 40 meters will be sufficient.

This article is a inquiry about how Barrès (1862-1923) handles the religious rite of pilgrimage. Barrès stages in his writings three successive forms of pilgrimage, revealing what is sacred to him at different times. The pilgrimage to a museum or to the birthplace of an artist is typical for the egotism and the humanism of the young Barrès, expressed in the Cult of the Self (1888-1891). After his conversion to nationalism, Barrès tries to unite the sons of France and to instill in them a solemn reverence for “the earth and the dead” ; for that purpose he encourages in French Amities (1903) pilgrimages to historical places of national importance (battlefields; birthplace of Joan of Arc), building what Nora later called the Realms of Memory. The third stage of Barrès’ intellectual evolution is exemplified by The Sacred Hill (1913). In this book the writer celebrates the places where “the Spirit blows”, and proves open to a large scale of spiritual forces, reaching back to paganism and forward to integrative syncretism, which aims at unifying “the entire realm of the sacred”.

The springboard for this essay is the author’s encounter with the feeling of horror and her attempts to understand what place horror has in philosophy. The inquiry relies upon Leonid Lipavsky’s “Investigation of Horror” and on various textual plunges into the fanged and clawed (and possibly noumenal) abyss of Nick Land’s work. Various experiences of horror are examined in order to build something of a typology, while also distilling the elements characteristic of the experience of horror in general. The essay’s overall hypothesis is that horror arises from a disruption of the usual ways of determining the boundaries between external things and the self, and this leads to a distinction between three subtypes of horror. In the first subtype, horror begins with the indeterminacy at the boundaries of things, a confrontation with something that defeats attempts to define it and thereby calls into question the definition of the self. In the second subtype, horror springs from the inability to determine one’s own boundaries, a process opposed by the crushing determinacy of the world. In the third subtype, horror unfolds by means of a substitution of one determinacy by another which is unexpected and ungrounded. In all three subtypes of horror, the disturbance of determinacy deprives the subject, the thinking entity, of its customary foundation for thought, and even of an explanation of how that foundation was lost; at times this can lead to impairment of the perception of time and space. Understood this way, horror comes within a hair’s breadth of madness - and may well cross over into it.

Burnout is a reality in the teaching profession. Specifically, teaching staff usually have higher burnout rates. The present study aims to analyze the different burnout profiles and to verify if there were differences between burnout profiles in depressive symptomatology and in the self-esteem of the teachers at school. The total number of participants was 210 teachers from 30 to 65 years. The first scale was the Maslach burnout inventory, the second scale was the Self-Rating depression scale and the third scale was the Rosenberg Self-Esteem Scale. The latent class analysis identified three burnout profiles: the first group with a high level of emotional exhaustion, low personal accomplishment and depersonalization (high burnout); the second group with low emotional exhaustion, low depersonalization and high personal accomplishment (low burnout) and the third group with low depersonalization, low emotional exhaustion and low personal accomplishment (moderate burnout). The results revealed that there were differences in depressive symptomatology (group 1 obtained higher scores than group 2 and group 3) and self-esteem (group 2 obtained higher scores than group 1). The psychological balance and health of teachers depend on preventing the factors that have been associated with this syndrome.

Cannabis Social Clubs (CSCs) are a nonprofit model for the supply of cannabis originating in Spain. This article aims to provide an overview of current CSC practices in Barcelona, exploring the role played by CSC Federations in shaping them. This analysis draws on 32 semistructured interviews with CSC managers ( n = 15) and with other stakeholders in Barcelona ( n = 17). We build also on field observations at other CSCs based in Barcelona. We found a heterogeneity of CSC practices, some of which were not in line with the self-regulatory codes developed by the CSC Federations. In applying an earlier CSC typology, we identified also country-specific CSC features. While the CSC Federations have contributed to unifying the cannabis movement and made efforts to homogenize CSCs’ practices, in the absence of (government) cannabis regulation, their efforts have to some extent been undermined.

In this article the self-hardening structure of stone based on calcium sulfate formation is described. Increase of strength of gypsum is possible by additional reinforcing of a stone ettringite crystals. The form and character of the formed crystals is defined by size рН. Dependence рН from the maintenance of additives was investigated in work. The limiting factor of formation of crystals of an ettringite of a necessary look is the maintenance of an additive. In work gypsum composites with the improved physical-mechanical properties on the basis of the modifying complex are received and investigated.

Abstract The first part of this essay treats Eriugena's concept of theophany. Because nature is to be understood as theophany, every visible and invisible creature is a divina apparitio. The second part explains that appearing nature is the metaphor of a creative principle. Metaphor is the inner structure of nature as a process of appearance and the inner structure of our speaking about nature as metaphor. The third part infers that the recognition of nature as metaphor is based upon the thinking of appearance. To understand the cause through which every phenomenon of nature becomes a metaphor means to understand the dialectic of appearing nature: it means to understand nature as apparitio non apparentis. The fourth part concludes that in moments of beauty we recognize the nature of metaphor and nature as metaphor. Beauty is the givenness of what we think as the vivid cause of appearing nature. Its cause - and beauty fundamentally - is the self-consciousness of nature as appearance. Both nature as well as beauty are nonmetaphorical metaphors of themselves.

This paper focused on the structure of the growth stories, especially in surveying Gangbaek Lee’s (이강백) drama “Like Looking at the Flower in the Mid-winter (동지섣달 꽃 본 듯이)”. It is structured by ‘rule of the three’. In this text, three sons go to seek their mother, they experience the tests three times. Third son wins the game because he succeeds to find his true and alternative mother. It is similar to the story of English fairy tale “Three Little Pigs”.  In Freudian terms, the characters of the both texts are superego, ego and id. The core of the growth story is that third son (id) wins the first son (superego) and the second son (ego) by using his own energy (meaningful labor). In Levi Strauss’ terms, the contrast between the third and the others can be schemed the contrast between culture and nature. Lee’s drama presents the third son as the real hero who overcomes two elder brothers. The first is so conservative (oversleep), the second is so selfish (overeat). Two brothers were too political or too ideal to become a true, humanistic and warm-minded adult. In his view, ‘drama’ related to the third son is the most humanistic and warm-minded action in the world. These both stories are based on the plot ‘rags to riches’ which contains the success of the poor and powerless. In other words, the poor and weak child can grow to the true hero, and reach the final destination, according to the Gustav Jung’s expression, ‘the Self as a Whole’.

ABSTRACT In Podospora anserina, protoplasmic incompatibility (a phenomenon that prevents heterokaryon formation because of the destruction of the fused cells) can be studied in homokaryotic strains that combine nonallelic incompatibility genes or carry mutations at the lys loci. In these strains cell destruction occurs early in development and is associated with an arrest of growth.—From the self-lysing strains lysA(1) and RV (R and V are nonallelic incompatibility genes) mutations have been selected that suppress the self-lysing trait, i.e., that prevent cell destruction and remove growth inhibition. Some of them were derived from a novel modifier locus, modC, located near the mating-type locus.—In C/D and C/E incompatibility systems, modC mutations, which per se have no obvious effect, were considered in addition to mutations in the previously identified modifier loci, modA and modB. The demonstration of a functional interdependence among the three mod genes suggested that modC is not the structural gene for the protease associated with cell lysis, but is involved, like modA and modB, in its control.—All three modC mutant strains investigated exhibit defects in the formation of protoperithecia, suggesting that the modC gene function is essential to the occurrence or development of the female organs. This is the third argument that supports the hypothesis (Boucherie, Bégueret and Bernet 1976) that protoplasmic incompatibility and female organ formation might be related phenomena.
