Algumas espécies podem causar prejuízos e danos ao homem, e ainda atuarem como vetores patogênicos em hospitais. Este estudo objetivou identificar as espécies de formigas presentes em um hospital da Zona da Mata Mineira, determinar o número médio de formigas visitando a isca por hora (NMFVIH), a similaridade entre os setores, a variação da diversidade nos períodos seco e chuvoso, além de identificar as estruturas físicas utilizadas como recurso para nidificação. Para a coleta da formigas foram utilizadas iscas atrativas não tóxicas, distribuídas a cada dez metros de distância nos seguintes setores: UTI Neonatal (UN), UTI Pediátrica (UP), Enfermaria Feminina (EF) e Entorno Hospitalar (EH). Registraram-se 42 espécies de formigas e quanto à riqueza obteve-se UN (n=4), UP (n=7), EF (n=13) E EH (n=30). Seis espécies foram classificadas como constantes, destacando-se Camponotussp.9, com 100% de ocorrência; 21 acessórias e 15 acidentais; Camponotus sp.4, Hylomyrmasp e Linepithemasp foram encontradas em todos setores. A subfamília Myrmicinae apresentou o maior índice de ocorrência (76,09%) e Ectatomminae com o menor (<0,01%). Os setores internos tenderam à similaridade, com exceção da UN no período seco e o número médio de formigas visitando a isca por hora diferiu significativamente entre as áreas interna e externa. O período de maior ocorrência foi entre às 12:00 e 17:59, período da tarde. Foram quantificados 28 ninhos, Interior Hospitalar (IH=23) e Entorno Hospitalar (EH=5), a categoria fresta foi a estrutura física mais utilizada (n=16) e tubulação (n=1) a menos. A espécie Camponotus sp.9 e Hylomyrmasp.1 nidificaram tanto no EH como no EF. A espécie registrada que mais se distanciou do ninho para forragear foi Attini sp.2 e a que menos se distanciou foi Linepithema sp.1. Conhecer a distribuição física do hospital, das formigas infestantes e a localização dos ninhos pode ser importante para determinar estratégias de controle. / The ants are social bugs with own characteristics that offer them to live and scatter to all terrestrial environments. Some species can cause damage and harm to humans, and still act as pathogenic vectors in hospitals. This study aimed identify the species of ants at a hospital in Zona da Mata Mineira, to determine the average number of ants visiting the bait by hour (NMFVIH), the similarity between the sectors, the variation of diversity in dry and rainy season, besides, identify the physical structures used as a resource for nest building. The ants were collect with non-toxic attractive bait distributed at each ten meters of distance in the following sectors: Neonatal ICU (NI), Pediatric ICU (PI), Women's Infirmary (WI), and the Surrounding area of the Hospital (HS). 42 species of ants were registered and the following diversity of species NI (n=4), PI (n=7), WI (n=13) and HS (n=30). Six species were classified as constant with emphasis for the Camponotussp.9, with 100% of occurrence; twenty-one ancillaries and fifteen accidentals; Camponotus sp.4, Myrmicini sp.1 and Linepithema sp.1 were found in all sectors. The subfamilyMyrmicinae had the highest rate of occurrence (76,098%) andEctatominae with the lowest (<0,01%). The internal sectors tended to similarity, except the NI in the dry season and the average number of ants visiting the bait per hour differed significantly between internal and external areas. The period of higher occurrence of ants used to be between 12:00 PM and 5:59 PM.28 nests were quantified in Area Interior (AI=23) and Area Around (AA=5), the gap category was the most used physical structure (n=16) and tubing (n=1) the lower. The species Camponotus sp.9 and Hylomyrmasp.1 nested both in HI and the HS. The registered species that more distanced itself from the nest to forage was Attini sp.2 and the one that less distanced it was Linepithema sp.1. The results showed that knowing the physical distribution of the hospital, the infesting ants and the location of the nests can be important for control strategies.

O caso de gestão estudado propõe uma análise do processo de gestão dos conflitos escolares em uma escola do Estado do Amazonas, na qual os índices de registro em livros de ocorrência são percebidos em assimetria no período que compreendem os anos de 2011 e primeiro semestre de 2015. O objetivo desse trabalho é subsidiar novas propostas para melhorias do ambiente escolar, por meio de um processo de mediação eficiente nos conflitos intraescolares. Para isso é necessário o reconhecimento do perfil dos relacionamentos interpessoais ocorridos entre escola e comunidade tendo por base os relatos dos registros de enfrentamentos postos no livro de ocorrências escolar. Para tanto utilizamos a método de análise documental, na qual fizemos um recorte ficando com apenas dezesseis registros em maior evidência. Esses registros foram classificados conforme quadros produzidos e definidos a partir dos referenciais teóricos. A partir das classificações, foram verificados registros com relatos em comum estabelecendo três categorizações de análise: agressão verbal, agressão física e comportamento irregular. Para essa utilizamos uma revisão bibliográfica que teve por base as ideias de Chrispino (2007), Abramoway e Mancini (2008), Nascente, Luis e Fonseca (2015) e Fonseca Rodrigues e Antonio (2012) porque tratam especificamente de temas abordados nas análises como: indisciplina, violência e conflito escolar e como são percebidos nas formas de utilização dos livros de ocorrência. Diante das análises foi constatado que não ocorre um processo de mediação de conflitos no ambiente da escola em estudo e que os processos ocorridos em meio aos registros só provocam outros conflitos. Também foi verificado que teor dos registros é reduzido e não oferece subsídios suficientes para os processos de análise e mediação do conflito. Frente a isso foi proposto um Plano de Ação Educacional que traz quatro ações que visam sistematizar os registros de ocorrência através de um formulário específico para que viabilizem informações eficientes para a mediação. Dentre essas ações também será oferecida uma formação para o sujeito educacional que poderá exercer a função de mediador e uma roda de conversas com alunos e demais comunitários que os motivem a utilizar essa nova ferramenta. / The current dissertation was developed under the Professional Master on Educational Evaluation and Management (PPGP) at the Center for Public Policies and Educational Evaluation of the Federal University of Juiz de Fora (CAEd / UFJF). The studied case proposes an analysis of school conflicts management process on a school situated in the State of Amazonas where the registration indexes in occurrence books are perceived in asymmetry in the period that comprises the years between 2011 and the first semester of 2015. This work aim is to support new proposals that may improve the school environment through efficient mediation on intra-school conflicts recognizing the interpersonal relationships profile between school and community through the records in scholar occurrence books. The utilized method was documental analysis, where the sixteen records in greater evidence were taken account. These records were assorted according to the models produced and defined by the theoretical references, just as the narratives were transcribed to the appendix of this dissertation. From the rankings, numerous records were verified and categorized in three different groups: verbal aggression, physical aggression and irregular behavior. The bibliographic review was based on the ideas of Chrispino (2007), Abramoway e Mancini (2008), Nascente, Luis e Fonseca (2015) and Fonseca Rodrigues e Antonio (2012) since it treat specific themes like the ones brought to analysis: indiscipline, violence and scholar conflict, showing how they are perceived in the perspective of an occurrence book. Within the analysis it was verified that there is no conflict mediation process in the school environment and that the processes occurring during the records only managed to generate other conflicts. It was also verified that the content of the records is insufficient and does not provide enough data for analytical process and mediation of the conflict. Therefore, an Educational Action Plan was proposed which brings four actions aiming to systematize the occurrence records through a specific form that enables efficient mediation upon the registered information. Among these actions, will also be offered training for the educational subject to act as a mediator and an informative talk for students and community, motivating them to use this new implement.

Monitoramento de moscas-das-frutas (Diptera, Tephritidae, Anastrepha) em nove municípios do Estado do Valle del Cauca, Colômbia / Monitoring of fruit flies (Diptera, Tephritidae, Anastrepha) from nine municipalities of the state of the Valle del Cauca, Colombia.

Marisol Giraldo Jaramillo 10 December 2007 (has links)
Neste estudo, são discutidas as moscas-das-frutas coletadas nos monitoramentos realizados pelo Instituto Colombiano Agropecuário (ICA), em nove municípios do estado do Valle del Cauca (Andalucia, Caicedonia, La Unión, Restrepo, Roldanillo, Sevilla, Toro, Tulúa e Zarzal), em diversas culturas (goiaba, mamão, café, laranja, pitahaya, etc.). Este estudo teve por objetivos: (1) identificar as espécies de Anastrepha e (2) analisar as populações das espécies mais freqüentes e numerosas. As moscas foram coletadas em armadilhas plásticas ou de vidro tipo McPhail com atrativo alimentar (proteína hidrolisada) por dois anos (janeiro de 2004 a dezembro de 2005). Nos nove municípios, foram capturadas 1.794 fêmeas de Anastrepha, sendo identificadas dez espécies: Anastrepha distincta Greene, 1934, A. grandis (Macquart, 1845), A. pallidipennis Greene, 1934, A. fraterculus (Wied., 1830), A. obliqua (Macquart, 1835), A. leptozona Hendel, 1914, A. mucronota Stone, 1942, A. serpentina (Wied., 1830), A. manihoti Lima, 1934 e A. striata Schiner, 1868. Anastrepha fraterculus foi a espécie mais freqüente (49% do total das capturas), seguida por A. striata (39,5%) e A. obliqua (7%). As sete espécies restantes, em conjunto representaram apenas 4,5% do total capturado. Anastrepha striata e A. obliqua foram coletadas nos nove municípios. Anastrepha striata foi a mais numerosa nos pomares comerciais de goiaba. Anastrepha fraterculus foi coletada em cinco municípios, mas 90% dos seus exemplares foram coletados em Sevilla e nenhum exemplar foi coletado em Roldanillo, La Unión e Toro. Esses municípios fazem parte da área selecionada para o estabelecimento do systems approach, visando à exportação de mamão aos EUA, por apresentarem áreas de baixa prevalência de A. fraterculus. Em Sevilla, foi coletado o maior número de espécies, sendo três coletadas apenas nos locais amostrados nesse município (A. distincta, A. manihoti e A. serpentina). Anastrepha leptozona e A. pallidipennis foram coletadas apenas em Toro. / This work was based on fruit flies collected during the monitoring conducted by the Instituto Colombiano Agropecuario (ICA) in nine municipalities of the Valle del Cauca province (Andalucia, Caicedonia, La Union, Restrepo, Roldanillo, Sevilla, Toro, Tulua, and Zarzal), on several crops (guava, papaya, coffee, orange, pitahaya, among others). This study had the following objectives: 1) to identify the species of Anastrepha, and 2) to analyze the populations of the most frequent and abundant species. The fruit flies were collected in plastic or glass McPhail type traps with feeding attractant (protein hydrolysate) during two years (from January, 2004 to December, 2005). In the nine municipalities, 1,794 females of Anastrepha of the following species were captured: Anastrepha distincta Greene, 1934, A. grandis (Macquart, 1845), A. pallidipennis Greene, 1934, A. fraterculus (Wied., 1830), A. obliqua (Macquart, 1835), A. leptozona Hendel, 1914, A. mucronota Stone, 1942, A. serpentina (Wied., 1830), A. manihoti Lima, 1934 and A. striata Schiner, 1868. Anastrepha fraterculus was the most frequent species captured (49% of the total captures), followed by A. striata (39.5%) and A. obliqua (7%). The other seven species accounted only for 4.5% of the total captures. Anastrepha striata and Anastrepha obliqua were captured in all nine municipalities Anastrepha striata was the most abundant on guava crops. Anastrepha fraterculus was collected in five municipalities, but 90% of the specimens were captured in Sevilla and none in Roldanillo, La Union or Toro. The former municipalities are part of the area selected to establish a systems approach under which papaya will be exported to the USA, since they bear areas of low prevalence for A. fraterculus. The highest number of species was captured in Sevilla, three were collected only in sites sampled in this municipality (A. distincta, A. manihoti, and A. serpentina). Anastrepha leptozona and A. pallidipennis were captured only in Toro.

A frequência do TDAH em pacientes com epilepsia e as correlações dos fatores de risco com as alterações do comportamento e psicossociais não estão totalmente elucidadas. Este estudo teve como objetivo verificar em pacientes com epilepsia a frequência do TDAH, as relações entre as variáveis clínicas, eletrencefalográficas, do tratamento, alterações psicossociais e do comportamento. Trata-se de um estudo transversal. Foram entrevistados 100 pacientes e selecionados 85 pacientes (na faixa etária entre seis e 16 anos de vida) que atenderam os critérios de inclusão. Sessenta pacientes foram diagnosticados com epilepsia de etiologia genética sem encefalopatia epiléptica (grupo I) e 25 pacientes apresentaram diagnóstico de epilepsia de etiologia estrutural-metabólica e de etiologia desconhecida (grupo II). Após detalhada caracterização clínica e eletrencefalográfica, aplicou-se a escala de pontuação para pais e professores MTA-SNAP-IV, a escala de Conners para pais na versão longa revisada e a escala de comportamento adaptativo Vineland. TDAH ocorreu em 8/60 pacientes do grupo I (13%) e em 12/25 pacientes do grupo II (48%). TDAH foi significantemente mais frequente nos pacientes do grupo II do que no grupo I (p=0.02). Os pacientes do grupo II apresentaram mais crises epilépticas (p=0.01), menor controle das crises epilépticas (p=0.01), maior uso de politerapia (p=0,01) e baixos escores (p=0.04) na escala de Vineland (domínio da comunicação) que os pacientes do grupo I. A comorbidade epilepsia-TDAH ocorreu em 23,5% da nossa casuística. As crises epilépticas esporádicas e bem controladas com monoterapia foram variáveis importantes para a baixa ocorrência do TDAH e alterações do comportamento e psicossociais / Abstract: Attention deficit and hyperactivity disorder (ADHD) occurs in 0.2 to 27% of all children with epilepsy. The frequency of the ADHD in patients with epilepsy, and the correlation with psychosocial aspects and behavior problems are not completely clear. The aim of this study was to verify psychosocial aspects and behavior problems in a group of patients with epilepsy and ADHD. This was a transversal study. One hundred patients were interviewed and eighty five patients (ages ranging from six to 16 years old) were selected and interviewed with a structured questionnaire. Sixty patients were diagnosed with epilepsy with presumably genetic etiology without epileptic encephalopathy (group I) and 25 patients were diagnosed with epilepsy with structural/metabolic etiology and unknown cause (group II). After clinical and EEG characterization, we used the MTA-SNAP IV Teacher and Parent Rating Scale, Vineland Adaptive Behavior Scales and the Conner's Rating Scales. ADHD occurred in 8/60 patients of group I (13%) and in 12/25 patients of group II (48%). ADHD was significantly more frequent in patients of group II than patients of group I (p = 0.02). Patients with ADHD in group II had significantly more seizures (p = 0.01), not well controlled (p = 0.02), used politherapy (p = 0.01) and lower scores (p = 0.04) in Vineland Scales (communication domain) than patients in group I. The comorbidity epilepsy-ADHD occurred in 23,5% of patients. Sporadic or well-controlled seizures and patients on monotherapy were important variables to predict lower rates of ADHD and behavioural abnormalities / Doutorado / Ciencias Biomedicas / Doutor em Ciências Médicas

Effect of Exergaming on Physical Activity of Adults with Intellectual Disabilities

Vergara, Jennifer Dawn 03 November 2017 (has links)
Physical inactivity is the fourth leading risk factor related to death (World Health Organization, 2016a). Thus, the World Health Organization (2016a) suggests engaging in at least 150 min of physical activity (PA) throughout the week. Many individuals with intellectual disabilities (ID) engage in sedentary lifestyles that raise concern about their long-term health. The purpose of this study was to evaluate the effects of exergaming on PA and intensity when implemented with adults with ID. Four adult males diagnosed with ID were recruited. During the scheduled phase, percent occurrence of PA was variable across both conditions for each participant. During the choice phase, all participants chose the exergaming condition. All ratings of intensity were attainable across both conditions for all participants. Results varied across participants. Participants reported high acceptability for exergaming.

Patterns in Words Related to DNA Rearrangements

Nabergall, Lukas 30 June 2017 (has links)
Patterns, sequences of variables, have traditionally only been studied when morphic images of them appear as factors in words. In this thesis, we initiate a study of patterns in words that appear as subwords of words. We say that a pattern appears in a word if each pattern variable can be morphically mapped to a factor in the word. To gain insight into the complexity of, and similarities between, words, we define pattern indices and distances between two words relative a given set of patterns. The distance is defined as the minimum number of pattern insertions and/or removals that transform one word into another. The pattern index is defined as the minimum number of pattern removals that transform a given word into the empty word. We initially consider pattern distances between arbitrary words. We conjecture that the word distance is computable relative the pattern αα and prove a lemma in this direction. Motivated by patterns detected in certain scrambled ciliate genomes, we focus on double occurrence words (words where every symbol appears twice) and consider recursive patterns, a generalization of the notion of a pattern which includes new types of words. We show that in double occurrence words the distance relative so-called complete sets of recursive patterns is computable. In particular, the pattern distance relative patterns αα (repeat words) and ααR (return words) is computable for double occurrence words. We conclude by applying pattern indices and word distances towards the analysis of highly scrambled genes in O. trifallax and discover a common pattern.

Anglická synonyma ze syntagmatického hlediska ve větném kontextu / English synonyms from the syntagmatic perspective in intrasentential context

Šefčík, Dominik January 2016 (has links)
Sense relations, traditionally regarded as primarily paradigmatic, have been shown to carry syntagmatic implications. The present thesis explores intrasentential synonym co-occurrence in order to identify characteristic patterns of such co-occurrence and to explain it with reference to the functions it performs in discourse. The theoretical part provides an overview of both general treatments of synonymy and the studies that deal with co-occurring synonyms. The analysis itself is based on two hundred and thirty sentences retrieved from the British national corpus that contain pairs of co-occurring adjectival synonyms such as confident-sure, faithful-loyal or brave-courageous. The findings suggest that adjectival synonyms co-occurring in the same sentence are typically coordinated (60% of analysed sentences) in order to signal semantic inclusiveness (e.g. a covetous and grasping man). Minor patterns of synonym co-occurrence, which accounted for 2% of the analysed sentences, include the scalar pattern (e.g. smooth, nearly urbane) and the negated pattern (e.g. cruel, not savage). The remaining sentences featured synonyms which did not form distinct patterns and were, accordingly, classified as instances of variation as their co-occurrence is likely to have been influenced by a desire to avoid...

Karin Raabová Supervisor: PharmDr. Jana Karlíčková, Ph.D. Diploma thesis 2016/2017, pp. 77 Ellagitannins belongs to a class of hydrolysable tannins, which are susceptible to hydrolysis to give ellagic acid in the digestive tract. Ellagitannins occur in many plant families, for example plants in the family Rosaceae, Myrtaceae or Lythraceae. There are naturally found in some fruits (pomegranate, strawberries, blackberries, raspberries, grapes), but also in the seeds of walnuts and thus form a diverse group of bioactive polyphenols with anti-inflammatory, antitumor, antioxidant and antimicrobial activity. Special instrumental methods (HPLC, DAD, MS) are most often used for subsequent evidence of occurrence of these compounds in plants and their identification. This diploma thesis is a literature review, which aimed at processing the available knowledge about the ellagitannins. Attention was focused on the biological activity demonstrated in an animal or human organism. Keywords: ellagitannins, occurrence, metabolism, effects, human body

Groundwater occurrence of Table Mountain area in Cape Town, South Africa

Wu, Changhong January 2009 (has links)
Magister Philosophiae - MPhil / Groundwater is an important water resource to be used to supplement the water demand for the City of Cape Town for present and future generations. Understanding the groundwater occurrence of the Table Mountain area is very important for future groundwater exploitation and management. Apart from the sea in the west, Table Mountain is mostly surrounded by the unconsolidated sediments including the Kirstenbosch, Newlands, and Oranjezicht areas. These areas are rich in groundwater resources, like springs; some of them were utilized, others not. However, there are few studies that focused on spring resource in this area. No up to date information is available for spring resources research and relative data is lacking from local research institutions. In fact, some of the spring resources in the Table Mountain area had been extracted and been utilized for local community for many years. Data and information newly obtained from this study about such groundwater resources will help future groundwater development and management. There are at least 13 springs in the selected study area. Those springs were investigated for groundwater occurrence, because spring is an important manifestation of the underlying aquifer through which groundwater dynamics can be detected. The main objective of the study was to sketch a clear picture of groundwater occurrence and to obtain an improved understanding of how geomorphology affects groundwater flow, its manifestation and quality. Water resources management is also important because this kind of water resource can be used to help meet the water demand of this local area in the future. There is relationship between the topographical features of the Table Mountain and spring occurrence. The research area delineated is used to interpret the relationship. Hydro-geochemical analysis is carried out to indicate the chemical components of the groundwater and to understand the groundwater type and water quality of this particular area. Based on the completed analysis and interpretation of factors influencing discharge and recharge, some good results were obtained and useful information is made available for first time. / South Africa

A developmental profile of speech sound and syllable acquisition in Zulu speaking children

Naidoo, Yugeshiree 02 March 2004 (has links)
This study investigated speech sound and syllable development in eighteen Zulu speaking children, between the ages of 3;0 to 6;2. In addition, the frequency of occurrence of Zulu speech sounds and syllables in this age group was investigated. To elicit a representative sample of the subjects’ natural speech, a 100-word spontaneous conversational sample was elicited from each subject. The samples were collected by a linguistically matched research assistant. All samples were transcribed phonetically by a stringent transcription procedure, and the reliability of the transcription was assessed by an external moderator. The UNIBET was used to code the transcription into computer recognisable symbols. The Phonetic Calculator Program (PCP) quantitively analysed the samples in terms of speech sound inventory, syllable inventory and the frequency of occurrence of speech sounds and syllables. The data was processed to allow for the comparison of the findings at three age levels namely, 3;0-4;0; 4;1-5;1 and 5;2-6;2. It was found that there was developmental progression between the ages of 3;0-6;2, with regard to speech sounds and syllables. It was found that much speech and syllable development occurred before the age of 3;0, and that the speech sound inventory and syllable inventory was incomplete by the age of 6;2. In addition, the nasals, plosives, approximants and fricatives were found to develop earlier than the affricates, clicks and prenasalised consonant sounds. The shorter syllable strings were found to develop earlier than the longer syllable strings. The subjects produced more speech sounds at an earlier age than their English-speaking peers. The subjects also produced longer strings of syllables at a younger age than their English-speaking peers. The findings in Group 1, Group 2 and Group 3 were similar to each other with regard to, the order of the speech sound frequency and syllable frequency. The more complex sounds and syllables were produced more frequently by the older subjects, demonstrating developmental progression. The findings have important clinical implications. Furthermore, the study can provide Speech-Language Therapists with a framework for further research, and contribute in constructing a relevant database of Zulu speech development. / Dissertation (MA (Communication Pathology))--University of Pretoria, 2005. / Speech-Language Pathology and Audiology / Unrestricted
