The present study conducted to study epipelic algae in the Tigris River within Baghdad city for one year from September 2011 to August 2012 due to the importance role of benthic algae in lotic ecosystems. Five sites have been chosen along the river. A total of 154 species of epipelic algae was recorded belongs to 45 genera, where Bacillariophyceae (Diatoms) was the dominant groups followed by Cyanophyceae and Chlorophyceae. The numbers of common types in three sites were 47 species. Bacillariophyceae accounted 88.31% of the total number of epipelic algae, followed by Cyanophyceae 7.14 % and Chlorophyceae 4.55%. A 85 species (29 genera) recorded in site 1, 103 species (34 genera) in site2, 112 species (35 genera) in site3, 96 species (32 genera) in site4, and 85 species (29 genera) in site5. Spatial and temporal distributions of epipelic algae were noticed in this study. The higher total number of epipelic algae (91504.01cell cm-2) was recorded at site 5 in spring 2012, while the lower was (37017.98cell cm-2) in summer 2012 at site1. Some genera have recorded higher number species during the study period; these genera were Nitzschia, Navicula, Cymbella, Gomphonema, Synedra, Achnanthes, Oscillatoria, and Lyngbya. The study revealed that Bacillariophyceae were more prominent within all study sites and followed by Cyanophyceae, while a few numbers of Chlorophyceae was appeared.

One year qualitative and quantitative study of communities of three major taxonomic groups has been carried out at test panles placed in the upper infarlittoral zone of coastal area of Vela Luka Bay, Croatia. A list of 44 taxa was recorded. <em>Chaetomorpha </em>sp., <em>Ulva </em>sp., <em>Fosliella farinosa</em>, <em>Sphacelaria cirrosa</em>, <em>Polysiphonia scopulorum </em>were the most frequent dominant taxa. Among 27 algal taxa with noticeable presence only three were classified as ESG (Ecological State Groups) I. Low diversity and species richness together with massive presence of the green algae (as <em>Ulva </em>sp.) and negligible presence of ESG I taxa, may lead to erroneous conclusion that Vela Luka Bay is eutrophicated area. Low values of biomass and <em>R/P </em>(Rhodophyceae by Phaeophyceae ratio) Index together with dominance of Phaeophyta also support conclusion that there is no negative impact of nutrient enrichment on macrophyta fouling community in Vela Luka Bay.

In order to assess the role of the megakaryocytes disturbance in several pathological thrombotic situations, we designed a technic for concentration and seperation of megakaryocyte population from bone marrow.Humann bone marrow megakaryocyte were isolated from sternal punction by two consecutive gradiebts of isosmoler Bovine serum albumine (B.S.A) solution in HANKS without Ca++ and Mg++ (Ph = 7.4) and density from 1.0024 to 1.0087 gm/ml at 1 g. Starting with Suspensions of bone marrow cells containing only 0.04% megakaryocyte, the proportion of megakaryocytes was enriched 50 times.Five populations of Rabbit megakaryocyte were separated by B.S.A. density gradient centrifugation from 1,050 to 1.098 gm/ml at 100 g dating 20 mn. The cytophotometric evaluation of megakaryocyte ploidy degree required a novel separation according to the megakaryocyte size by velocity sedimentation in B.S.A. gradient at 1 g. By these technics, the proportion of megacaryocyte was enriched 60 to 100 times in each homogenous class. Then, qualitative and quantitative study were realized by cytopkotametric evaluation of DNA-Feulgen at 560 nm and residues ariginyls and lysyls in histones at 370 and 592 nm and correlated with ultrastructural features. Thus modifications of megakaryocytopoiesis in atherosclerotic coronary disorder in Man and experimental atherosclerosis in rabbit were recognized.Supported by D.G.R.S.T. Grant 77.7. 1406

A presente pesquisa busca enfatizar a importância existente na articulação e na atuação con-junta dos órgãos públicos no combate à corrupção político-administrativa, sendo esta encarada como um entrave ao desenvolvimento humano. Desse modo, buscou-se realizar um estudo qualitativo e quantita-tivo da atuação do Ministério Público Federal (na figura da Procuradoria da República, situada em São Luís – MA), quando do recebimento dos relatórios de fiscalização por sorteios públicos realizados pela Controladoria Geral da União entre 2009 e 2011, os quais apresentam atos de improbidade do gestor público municipal. Da análise dos oito municípios maranhenses abordados na pesquisa, constatou-se que há uma fragilidade na articulação entre os órgãos de fiscalização e controle, os de investigação e Ministério Público Federal; verificou-se a existência de uma morosidade no encaminhamento e tomada de providências necessárias para que os casos apresentados como práticas ímprobas de gestoras muni-cipais, possam vir a se tornar Ações de Improbidade Administrativa, que, verdadeiramente sirvam como instrumento de combate à corrupção político-administrativa e, desse modo, como mecanismo de incenti-vo ao desenvolvimento humano.Palavras-chave: Ministério Público Federal.

Desenvolvimento.THE ROLE OF THE FEDERAL PROSECUTOR IN MARANHÃO STATE CONCERNING TO ACTS OF THE PUBLIC MUNICIPAL MANAGER ADMINISTRATIVE MISCONDUCT BETWEEN THE YEARS 2009 AND 2011: CORRUPTION AS AN OBSTACLE TO DEVELOPMENTABSTRACT: This research seeks to emphasize the importance existing in the articulation and the joint actions of public institutions to combat political and administrative corruption , which is seen as an obstacle to human development . Thus , it was to conduct a qualitative and quantitative study of the action of the Federal Public Ministry ( the figure of the Prosecutor’s Office , located in São Luis - MA ) , upon receipt of inspection reports by public drawings conducted by the Comptroller General between 2009 and 2011 , which feature acts of misconduct municipal manager . Through the analysis of the eight municipalities of Maranhão addressed in this study , it was found that there is a weakness in the joint between the bodies of supervision and control, research and federal prosecutors ; verified the existence of delays in referral and taking necessary measures so that the cases presented as misconducted practices of municipal management, are likely to become AP administrative Misconduct , which really serves as a tool to combat political and administrative corruption and thus , as an incentive mechanism to human development.KEYWORDS: Federal Prosecutor.

Entrepreneurship education is a complex topic that can be discussed from a variety of perspectives. One key question in the discussion concerns how one can adapt the general core principles of entrepreneurship education, many of which are closely linked to business education, to other academic areas that currently lack this type of education. This article discusses the challenges of developing a model of entrepreneurship education for the creative industries sector. Focusing specifically on film and media arts education, the authors examine the results of a qualitative and quantitative study of both industrial and educational (teachers and students) stakeholders’ perceptions of the relevance and role of entrepreneurship education in this field. In light of the results of the study, the authors propose a strategy and methodology for entrepreneurship education for the creative industries.

Objectives The aim of this study was to retrospectively review the effectiveness of negative pressure wound therapy (NPWT) in sternal wound healing with the use of the validated Bates-Jensen Wound Assessment Tool (BWAT), and explore the role of NPWT over sternal wounds and future treatment pathways. Methods Data was gathered from patients' medical records and the institution's database clinical management system. Seventeen subjects, who had undergone cardiothoracic surgeries and subsequently consulted the wound care team in one year were reviewed. Fourteen of them were included in the analysis. Healing improvement of each sternal wound under continuous NPWT and continuous conventional dressings was studied. In total, 23 continuous NPWT and 13 conventional dressing episodes were analysed with the BWAT. Results Among conventional dressing episodes, sternal wound improvement was 2.5–3% over 10 days to 3.5 weeks, whereas 4–5% sternal healing was achieved in 5 days to 2 weeks with sternal wire presence. Better healing at 11% in 1 week by conventional dressing was attained after sternal wire removal. In NPWT episodes, 8–29%, 13–24%, and 15–46% of healing was observed in 2 weeks, 3.5 to 5 weeks and 6 to 7 weeks, respectively. Only 39% wound healing was acquired at the 13th week of NPWT in one subject. With sternal wire present, 6%–29% wound healing progress was achieved by NPWT in 1–4 weeks, and 16–23% wound improvement in 2 to 4.5 weeks by NWPT after further surgical debridement. After sternal wire removal, 6–34% sternal wound healing occurred by continuous NPWT for 1–2 weeks, and maximum healing at 46% after 2.5 weeks of NPWT were observed. Conclusions Better wound healing was achieved in the NPWT group in comparison to conventional dressings alone. However, suboptimal sternal wound healing by NPWT alone was observed. Removal of sternal wire may improve the effectiveness of NPWT. Successful tertiary closure after NPWT among subjects supports the important bridging role of NPWT in sternal wound healing. Factors causing stagnant sternal wound healing by NPWT alone are discussed.

ABSTRACT The ovaries of ten patients, at least one year after the post-menopause, were incubated with two Δ5-C19-steroids and also studied histochemically. All these patients had post-menopausal uterine bleeding and increased oestrogen excretion of the urine. The urinary estimations of gonadotrophins, 17-KS, 17-OHCS and pregnanediol were carried out on all patients. Vaginal smears were read according to Papanicolaou, and the endometrium and ovaries were studied histologically. The incubation experiments indicate the presence of Δ5-3β-hydroxysteroid-dehydrogenase. When androst-5-ene-3β,17β-diol was used as precursor the formation of testosterone occurred without any concomitant production of DHA and/or androstenedione. This seems to indicate the possible role of the Δ5-pathway in the formation of testosterone by post-menopausal ovarian tissue. The histochemical reactions indicated a reducing activity on NADH, lactate and glucose-6-phosphate, in certain corpora albicantia, atretic follicles and in diffuse thecoma regions in the cortical layer of the ovary. Steroid-3β-ol-dehydrogenase and β-hydroxybutyrate-dehydrogenase were found only at the edges of certain corpora albicantia, in some individual stroma cell groups and in some atretic follicles. Our studies, both biochemical and histochemical, suggest that the observed increase in the urinary oestrogens of the patients studied might in part at least, be of ovarian origin. This opinion is also supported by the postoperative oestrogen values.

Chess playing has a significant role in participants’ resources allocation, both at a psychological level, but mostly concerning the cognitive resources. The aim of the present study was to examine the effect of chess playing on the intellectual development of primary-class students. 67 children were tested using the Raven Standard Progressive Matrices and were distributed in three different groups according to their experience with chess, namely: the control group (formed by students with no experience with chess playing), the beginners group (students with less than one year in chess playing training) and the advanced group (children with more than two years experience with chess). Results indicated that chess playing had a significant effect on the SPM performance, indicating that those in the advanced group performed significantly better than those in the control or in the beginners group. Conclusions of this study tap into the benefits of playing chess with a focus on the children’s’ cognitive development.
