El objetivo fue determinar los efectos de los factores para el establecimiento de microesquejes de papaya. Se incluyeron los efectos de los factores: 1. Protocolo de desinfección. 2. Variedad. 3. Edad de la planta donadora. 4. Número de yemas por microesquejes. 5. Los componentes hormonales en los medios de cultivo y 6. La temperatura de desarrollo de los microesquejes. Los resultados se analizaron estadísticamente mediante tablas de contingencia. También se encontró la correlación entre las variables. Los resultados indican que las mejores condiciones para el establecimiento de los microesquejes fueron: 1.Desinfección con hipoclorito al 1,5% durante 5 minutos. 2. La variedad de papaya Roja Melonera. 3. La edad optima de las plantas donadora fue a los 60 días. 4. Los mejor microesquejes eran los que poseía 2 yemas. 5. La relación hormonal optima fue ANA 0,1 mg/l y BAP 0,5 mg/l. 6. La temperatura de desarrollo óptima fue a 27° C. Se concluyó que todos los factores estudiados presentaron efecto sobre el desarrollo y crecimiento de los microesquejes de papaya. De esta forma es necesario abordar estos procesos con un enfoque multifactorial.Palabras clave: Carica papaya, microesqueje, establecimiento, multifactorial. AbstractPrevious studies on apical and axilar microesqueje micropropagation of papaya have been lined up and without a systemic working. Consequently, it arises the actual research, which brough into study all the variables and parameters and their relationships, in order to improve the vitroplants production process, more efficiently. The main purpose of this study was to establish the effects of the former and in vitro factors, which have incidence upon the establishment of microesquejes. The effects of the former variables previous to the in vitro growing, which were studied, were: Sanitizing procedure, variety incidence, mother plant age incidence, among other ones. On the other hand, the in vitro variables studied were: temperature and hormonal compositions of the crops. Respuestas Año 15 No. 1 Junio 2010 ISSN 0122-820X This research was held at the vegetal biotechnology laboratory, which belongs to the biotechnology complex of the Universidad Francisco de Paula Santander in “Los Patios” Norte de Santander, Colombia. The experimental procedure was held with two months old plants from “Maradol” and “Roja Melonera” varieties. In order to accomplish the different effects of each one of the variables, it was used qualitative statistical method for their measurements. The final results showed that all factors were important to the papaya microesquejes micro propagation. As a result, the actual conclusion was to introduce the necessity to give a systemic focusing to the process in order to improve the efficiency in the vitroplants production, where all the factors and their relationships must be considered. Finally, the most important goal of this study is that all these results could be extended beyond other researches related to tropical fruits micro propagation, so important to the tropical micro propagation workers. Key Words: Carica papaya, microcuttings, establishment, multifactors.

Background: Pigmented tumour of the skin is one of the common tumour in human including the benign pigmented tumours (more common) called Nevi tumours and the malignant one called melanoma which was less frequent but the most poor in prognosis. In addition, the others not belonging to these group had the same clinical appearance, so the application of histopathology and immunohistochemistry for the definitive diagnosis was indespensible. Objectives: 1. To describe the macroscopic features of the pigmented tumoral-like lesions; 2. To classify the histopathologic types of the pigmented cell tumours and the other pigmented tumours of the skin. Materials and Method: Cross-sectional research on 55 patients diagnosed as pigmented tumoral lesions by clinician, then all definitively diagnosed by histopathology combining the immunohistochemistry in difficult cases. Results: There was no difference in gender, the disease was discovered most common in adult, especially with the age over 51 years old (58.1%). the most region located was in the face accounting for 60%, following the trunk and limbs (14.6%, 12.8% respectively). All 3 malignant melanomas happened in foot. The most common color of the lesions was black (65.4%), the other ones were rose, grey and blue. Histopathology and immunohisthochemistry showed that the true pigmented cell tumours were 52.6% encompassing benign ones (Nevi tumour) (41.8%), melanoma (5.4%) and lentigo (5.4%). 47.4% was not the true pigmented cell tumour including pigmented basocellular carcinoma (36.4%) and the others less common as histiofibromas, acanthoma and papilloma. Conclusion: the pigmented tumoral-like lesions of the skin could be the true pigmented cell tumours and the others, so the application of the histopathology and the immunohistochemistry after the clinical discovery helps to determine and classify the disease definitely and for the best orientation of treatment as well. Key words: skin tumour, benign pigmented tumour (Nevi), malignant pigmented tumour (melanoma), pigmented basocellular carcinoma

The efficacy of seed treatment and foliar spray with fungicides in controlling black point incidence of wheat seeds was evaluated in the field. Two seed treating fungicides, namely Vitavax-200 and Homai-80WP were used @ 0.25% of dry seed weight and foliar spray with Tilt-250EC (0.05%) was applied in six different schedules. Untreated and unsprayed controls were also maintained. Seed treatment with either Vitavax-200 or Homai-80WP significantly increased plant population and grain yield, but none of them was found effective in reducing black point incidence. On the other hand, foliar sprays with Tilt-250EC under all the spray schedules except spraying at 70 and 90 DAS significantly minimized the disease severity over unsprayed control. Among the different spray schedules, spraying at 30, 40, 50, 60, 70, 80, and 90 DAS appeared to be most effective, which was similar to spraying at 30, 45, 60, 75, and 90 DAS in reducing black point incidence and increasing grain yield. Economic analysis on yield advantage showed that the highest additional gross margin of Tk. 6120/ha with BCR 2.57 was obtained from five sprays applied at 30, 45, 60, 75, and 90 DAS. Key Words: Seed treatment, foliar spray, black point, wheat. DOI: 10.3329/bjar.v34i3.3968 Bangladesh J. Agril. Res. 34(3) : 425-434, September 2009

The Candida antarctica lipase B-catalyzed reactions of five β-amino esters with neat butyl butanoate and with 2,2,2-trifluoroethyl butanoate in diisopropyl ether were studied, as were the reactions of the same β-amino esters and their N-butanamides with neat butanol. The possibility for sequential resolution, where the amino and ester functions of the substrate both react with an achiral butanoate, became less likely with increasing size of the substrate from ethyl 3-aminobutanoate (1a) to pentanoate (1b) or larger. On the other hand, the alcoholyses of N-acylated β-amino esters successfully proceeded in butanol with E > 100. Gram-scale resolution of the N-butanoylated 1a was performed to demonstrate the usefulness of the method. Key words: lipase, interesterification, acylation, alcoholysis, resolution, β-amino esters.

Field experiments and survey methods were used to assess competition and interaction between Lemna minor L. and Lemna trisulca L. at Delta Marsh, Manitoba. Sites were dominated by one or the other species or codominated by both. Replacement series experiments predicted codominance of L. minor and L. trisulca in an unshaded eutrophic site but predicted L. minor dominance when run for a longer time. Similar experiments conducted in a shaded eutrophic site predicted L. minor dominance. Addition series experiments showed that intraspecific and interspecific competition occurred in the unshaded site. In a eutrophic unshaded ditch, high densities of L. minor suppressed L. trisulca. In a eutrophic shaded site, high densities of L. minor and green algae inhibited L. trisulca, and in a sunny, less eutrophic site high density of each species inhibited the other. In a transplant experiment, L. minor biomass in shaded enclosures approached that found naturally in two shaded sites. Lemna trisulca persisted when shaded. Vegetative biomass trends in an unshaded eutrophic marsh ditch indicated spring and fall L. trisulca dominance and summer L. minor dominance. Shaded eutrophic sites were dominated by L. minor, whereas a less eutrophic site was dominated by L. trisulca. A model is developed to explain dominance patterns, and seasonal life-history responses are considered. Key words: Lemna, duckweed, competition, interaction, resources, light, nutrients.

- Image The present article focuses on two topics underlying the lecture given by Maurice Merleau-Ponty in 1945 at the Institut des Hautes Études Cinématographiques, in Paris. One is the reflection on the peculiarities of filmic expression and cinematic image; the other, the convergence between the inspiration of cinema and that of philosophy, which Merleau-Ponty sees as a significant feature of his time: a convergence which the cinema of the nouvelle vague was also to acknowledge and which Christian Metz was to confirm retrospectively. Moreover, in developing both topics, the author finds a way to interpret Merleau-Ponty's lecture as an undeclared polemical response to Henri Bergson's famous negative judgement on cinema.Key words: Cinematic Image, Gestalt Psychology, Melody, Montage, Perception, Rhythm.Parole chiave: Dinamica di legittimazione, Immagine, Identitŕ, Narrazione, Soggetto, Tempo.

Aim: This paper aims to analyse the self-efficacies of coaches of different branches. Methods: This study, which was conducted by using coach self-efficacy scale, reached totally 192 volunteering coaches who lived in Çanakkale and Balıkesir. The data collected were then analysed on the SPSS programme. The kurtosis and skewness values were examined so as to check the distribution of the data, and consequently, the data were found to have normal distribution. Results: As a result, statistically significant differences were found between the coaches aged 28-32 and coaches aged 33-37 in their levels of self-efficacy in general and in the sub-factor of efficacy in impersonating. Accordingly, the coaches who were in 28-32 age group had higher self-efficacy and efficacy in impersonating than the ones who were in 33-37 age group. On the other hand, there were no statistically significant differences between the participants’ levels of self-efficacy according to gender, branch and professional experience. Conclusion: The coaches in the 28-32 age group were found to have higher self-efficacy and efficacy in impersonating than the coaches in the 33-37 age group on examining the results obtained. No differences were found between the participants in the other factors. Key Words: Self-efficacy, coaches, sport

<p><strong>Background:</strong> Corporate entrepreneurship (CE) is credited for many positive organisational outcomes, including systemic growth and increased revenue. Several terms associated with CE, including strategic renewal, corporate venturing and intrapreneurship are frequently used interchangeably and often confuse scholars, researchers and practitioners. The lack of clarity about the exact meaning of these terms is detrimental to the synergy in the current body of knowledge and the development of models involving these concepts. Objective: The aim of this paper was to describe CE as a unique concept, distinguishable from related concepts. Methodology: Several definitions of CE as well as the related terms were dissected, to identify core elements associated with each of them. The validity of these comprehensive definitions was tested by requesting 68 master’s degree students to classify the definitions. Inter-rater reliabilities were calculated in order to assess the level of agreement in the classification of the constructs. Results: The results indicate that CE is difficult to distinguish from strategic renewal and corporate venturing, but that intrapreneurship seems to be better defined and separate from the other constructs. Conclusion: These results emphasise the conceptual confusion that exists around CE and the need for further clarification of terminology.</p><p><strong>KEY WORDS</strong></p><p>Corporate entrepreneurship, strategic renewal, corporate venturing, intrapreneurship.</p>

We have evaluated the experimental evidence relevant to the structure and character of mesoionic compounds, accumulated for more than 100 years and including X-ray diffraction studies. We have also evaluated relevant theoretical studies. All these, including our own extensive work, lead us to conclude that mesoionic compounds are not aromatic. According to our recent definition “mesoionic compounds are planar five-membered heterocyclic betaines with at least one side chain whose α-atom is also in the ring plane and with dipole moments of the order of 5 D. Electrons are delocalized over two regions separated by what are essentially single bonds. One region, which includes the a-atom of the side chain is associated with the HOMO and negative π-charge whereas the other is associated with the LUMO and positive π-charge.” Key words: mesoionic compounds, betaines, aromaticity.
