Infrared thermography was used to compare differences in extent and duration of inflammation observed on hot-iron and freeze brand sites as an indicator of tissue damage and the associated discomfort to the animals. Thirty beef heifers of mixed breed were assigned to either hot-iron (H) or freeze (F) branding treatments according to a predetermined randomized branding order. Ten animals were branded each day over a 3-d period. On the day prior to branding, animals were clipped to expose two patches of skin; one to be used for the branding treatment and the other for a control. Thermographic images of control and treatment sites were made at 0.08 h (5 min) prior to branding, immediately after the brand was completed (0 h), as well as 0.08, 2, 4, 8, 12, 24, 48, 72, 96, 120, 144 and 168 h after branding. Control site temperatures were subtracted from treatment site temperatures for each individual animal. Both F and H brand sites were consistently warmer (1.9 ± 0.3 and 1.6 ± 0.3 °C, respectively) than their corresponding control sites between 2 and 168 h after branding. Treatment differences were obtained at 0, 0.08, 2, 8, and 144 h after branding (P < 0.001, 0.05, 0.005, 0.001, and 0.01, respectively). Freeze brand sites were warmer at 2 and 8 h after branding while H sites were warmer at 144 h after branding. The thermographic evaluation of hot-iron and freeze brand sites indicated that both methods caused tissue damage. However, H brand sites remained significantly warmer than F sites at 168 h after branding. In addition, H sites were significantly warmer than control sites while F sites were not warmer than control sites at 168 h. The prolonged inflammatory response observed in H animals indicates that more tissue damage and perhaps more discomfort are associated with H branding.

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

Farm Economics

In beef herds, increasing animal welfare, improving reproductive performance and easing animal management are key goals in farm economics. We explored whether delaying the removal of the intravaginal progesterone device by 24 h in heifers synchronized with a 5d Co-synch 72-h protocol could improve reproductive efficiency of fixed-time artificial insemination (FTAI). In experiment 1, we examined the total synchronization rate (TSR) in cycling Holstein heifers. Heifers (13.4 ± 0.69 mo.) were randomly assigned to the standard 5d Co-synch 56-h protocol (5dCo56; n = 10), 5d Co-synch 72-h (5dCo72; n = 17), or the modified 5d Co-synch 72-h protocol, in which removal of the progesterone device was delayed by 24 h (6dCo48; n = 19). In experiment 2, 309 cycling beef heifers on 18 commercial farms were subjected to the 5d Co-synch 72-h or 6-d Co-synch 48-h protocol and conception rate (CR) studied. In experiment 1, the three protocols led no differences on TSRs of 80.0% (5dCo56), 88.2% (5dCo72), and 89.5% (6dCo48). In experiment 2, the CR from the beef heifers, observed during two consecutive reproductive seasons did not differ: 59.7% for 5dCo72 and 62.0% for 6dCo48 (p = 0.907). Therefore, delaying removal by 24 h provides satisfactory results without reducing reproductive efficiency of heifers.

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.

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.

Lung Tissue Damage

Studies have shown that the severity and outcome of acute pneumonia largely depends on the prevalence of the focus of inflammation in the lung tissue, which is determined radiologically. We analyzed and determined a statistically significant effect of the degree of lung tissue damage on the severity and prognosis of pneumonia in young children, taking into account the conditions of infection. In pneumonia, χ² = 47.13 (p <0.001), indicates that the greater the degree of damage, the greater the likelihood of a severe course and unfavorable outcome of pneumonia.

- 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>

A 3-year-old, male mixed breed dog with botulism and bilateral descemetocele was submitted to lamellar keratoplasty with equine renal capsule preserved in glycerin in the right eye and conjunctival pedicle graft in the left eye. The evolution was satisfactory in both eyes, but better in the eye receiving the equine renal capsule, because the corneal transparence was more evident in that eye. On the other hand, the surgical period was more quickly in the eye receiving the equine renal capsule because the preparation of the conjunctival pedicle before the keratoplasty was not necessary.
