This article reveals the results of experiments conducted to study the influence of the planting scheme on the viability of the varieties of kiwifruit plant introduced to our republic in their reproduction from softwood cuttings. The experiments were conducted on a special substrate in a microclimate-controlled facility. Hayward variety of the kiwifruit plant served as the object of study. Softwood cuttings of kiwifruit varieties were studied by planting in eight different schemes. The results of the study showed that the rooting of kiwifruit varieties from softwood cuttings was higher as the distance between them decreased. However, in terms of seedling yield per unit area, the planting schemes 10×20 and 15×15 cm were recommended in the production.

It is well known that a large flux of electrons must pass through a specimen in order to obtain a high resolution image while a smaller particle flux is satisfactory for a low resolution image. The minimum particle flux that is required depends upon the contrast in the image and the signal-to-noise (S/N) ratio at which the data are considered acceptable. For a given S/N associated with statistical fluxtuations, the relationship between contrast and “counting statistics” is s131_eqn1, where C = contrast; r2 is the area of a picture element corresponding to the resolution, r; N is the number of electrons incident per unit area of the specimen; f is the fraction of electrons that contribute to formation of the image, relative to the total number of electrons incident upon the object.

Considering any finite three-dimensional object, a “projection” is here defined as a two-dimensional representation of the object's mass per unit area on a plane normal to a given projection axis, here taken as they-axis. Since the object can be seen as being built from parallel, thin slices, the relation between object structure and its projection can be reduced by one dimension. It is assumed that an electron microscope equipped with a tilting stage records the projectionWhere the object has a spatial density distribution p(r,ϕ) within a limiting radius taken to be unity, and the stage is tilted by an angle 9 with respect to the x-axis of the recording plane.

A scanning electron microscope (SEM) study was made of the effect of adrenocorticotropic hormone (ACTH) on the size and numbers of fenestrae/unit area in the capillary endothelium of the zona fasciculata (ZF) of the rat adrenal. The stimulatory effect of ACTH on cholesterol uptake via high density lipoproteins in the rat and evidence for the secretion of glucocorticoids by exocytosis of lipid droplets described by Rhodin suggest that endothelial change may accompany these transport phenomena.Twelve rats received two Dexamethasone (DEX) ip injections (25 μg DEX/100 g body wt.), the first at 8 PM and the second at 8 AM the next day, to inhibit the release of endogenous ACTH by the anterior pituitary. The animals were then divided into two groups. Six animals received only saline vehicle and six rats received ACTH (100 ng/100 g body wt.).

Protein A-gold immunocytochemistry is a two-step, post-embedding labeling procedure which may be applied to tissue sections to localize intra- and extracellular proteins. The key requisite for immunocytochemistry is the availability of the appropriate antibody to react in an immune response with the antigenic sites on the protein of interest. During the second step, protein A-gold complex is reacted with the antibody. This is a non- specific reaction in that protein A will combine with most IgG antibodies. The ‘label’ visualized in the electron microscope is colloidal gold. Since labeling is restricted to the surface of the tissue section and since colloidal gold is particulate, labeling density, i.e., the number of gold particles per unit area of tissue section, may be quantitated with ease and accuracy.

It has been hypothesized that typical speech movements do not involve large muscular forces and that normal speakers use less than 20% of the maximum orofacial muscle contractile forces that are available (e.g., Amerman, 1993; Barlow & Abbs, 1984; Barlow & Netsell, 1986; DePaul & Brooks, 1993). However, no direct evidence for this hypothesis has been provided. This study investigated the percentage of maximum interlabial contact pressures (force per unit area) typically used during speech production. The primary conclusion of this study is that normal speakers typically use less than 20% of the available interlabial contact pressure, whether or not the jaw contributes to bilabial closure. Production of the phone [p] at conversational rate and intensity generated an average of 10.56% of maximum available interlabial pressure (MILP) when jaw movement was not restricted and 14.62% when jaw movement was eliminated.

SummaryThe diverging collimator makes it possible to increase the field of view of a radioisotope imaging camera. The larger field of view is obtained by sacrificing efficiency per unit area of the field of view while preserving the resolution of the system. This situation is analogous to that of the scanner, where the efficiency per unit area is inversely proportional to the total area scanned.Efficiency and resolution of diverging collimators can be calculated quite accurately as is evidenced by the good agreement between calculated and measured values. The problem of septum penetration, however, needs to be further investigated for both parallel-hole as well as diverging collimators, so that the influence of the shape and arrangement of the holes upon septum penetration is taken into account.

This research is motivated by the lack of interest of teachers in the use of props in the process of learning mathematics in elementary school. In accordance with the demands of the curriculum in 2013 and supported by the developed learning theory, learning mathematics is abstract object of study, students need an intermediary that props math-ematics, so that students can more easily understand the concepts that will be pre-sented, and in the end it can deliver students to solve mathematical problems, not only that proposed by the teacher but also the problems in life. The purpose of this study was to determine the interest of prospective elementary teachers on the use of props mathematics after getting lectures media and elementary mathematics learning model. By knowing the interest of prospective elementary teachers will be developed further realization of the state of the subject being studied. The method used is descriptive research, then the instruments used were questionnaires and interviews. The results of this study stated that the interest of prospective elementary teachers on the use of props after attending lectures media and elementary mathematics learning model is high over-all with a percentage of 76.70%.Keywords : Interest, Props Mathematics

Psychology and sociology share a common object of study, human behaviour, but from different perspectives. Sociologists have focused on macro variables, such as social structure, education, gender, age, race, etc., while psychology has focused on micro variables such as individual personality and behaviours, beliefs, empathy, listening, etc. Despite the importance of interpersonal relationship skills, they depend on the community or social context in which communication takes place, and by themselves may have little relevance in the consultation. The purely psychological analysis of the doctor-patient relationship often leads to an idyllic vision, with the patient-centred consultation as the greatest exponent, which rarely occurs in real life. The purely sociological or community / social analysis of the doctor-patient relationship leads to a negative view of the consultation, which is always shown as problematic. But, the psychological system in the doctor-patient relationship cannot be neglected, and its study is of importance, at least as an intermediate mechanism that is created through socio-community relations. Although the same social causes are behind the doctor-patient relationship, when acting on psychological factors in the consultation, they act as an optical prism scattering socio-community relations that affect the doctor and the patient, giving rise to a beam of different colors of doctor-patient relationship. In doctor-patient relationship there is a modality of psychotherapy, where attitudes, thoughts and behaviour of the patient, can be change, as well as it can be extended on the way of understanding and therefore changing, his social context. Because of the distance between socio-community relations and the form of doctor-patient relations is growing in complex societies, under these conditions, the sociological factor gives the important place to the psychological factor. Given these difficulties of the doctor-patient relationship one may ask how general medical practice can persist with the usual model of doctor-patient relationship. Pain and the desire to relieve them are the basic reasons for the patient and the doctor, and they do not disappear due to the contradictions of the doctor-patient relationship. In this way, the confrontation between sociological and psychological vision is replaced by an alliance of both currents, and each of them takes on meaning only in the general vision.

This essay, in response to Michael Kaler and Philip Tite, examines several theoretical issues about mystical experience in the Nag Hammadi texts. First is the problem of whether experiences can be an object of study at all, and I argue that they can, so long as we attend to the causes of the experiences. Attending to the causes of experiences, however, means that neo-perennialists must articulate and defend an account of the cause(s) of the cross-culturally universal experiences that they suppose occur. As for the attempt to apply contemporary psychologists' attachment theory to the experiential knowledge described in the Nag Hammadi texts, questions remain about the relation between attachment to the divine figure purportedly experienced and the experiencer's attachment to his or her religious community.
