Texte intégralRésumé :
OBJECTIVE: To determine the frequency of patients with various anatomical forms of the hard palate for complete denture fabrication and to compare the mean distortion in heat cure denture base polymer in millimetres in different hard palate forms. METHODOLOGY: Informed consent was taken from total of seventy six patients and divided into low and medium hard palate forms. Dental casts were prepared from alginate impression and poured in type III stone and reference point R was marked on the deepest part of the posterior palatal seal area at the junction of hard and soft palate on each cast. After curing, the cast along with the cured denture base was retrieved from the flask. After 48h of curing cycle the distortion was measured in millimetres from R to R' via traveling microscope. RESULTS: Among seventy six participants the frequency of low palate forms was 45 (59.2%) and medium palate forms was 31 (40.8%). For each sample three readings were taken R1, R2 and R3. The mean distortion measured in low hard palate form was 0.52mm with a standard deviation of 0.18, the mean distortion measured in medium hard palate form was 0.76mm with a standard deviation of 0.27, which were clinically significant with a p-value of 0.0001. CONCLUSION: The hard palate forms has direct influence on retention of maxillary complete denture in posterior palatal area. KEY WORDS: Heat Cure denture base, distortion in hard palate forms, dimensional changes in heat cure, hard palate anatomy and denture bases

Texte intégralRésumé :
The oldest known microsaur is preserved in a nodule from the Kinkaid Formation (Mississippian; Elvirian) collected near Goreville, Illinois. At least eight individuals are represented: three by partial skulls plus vertebral column segments with associated limb elements, and five by postcrania only. Skulls are crushed, incomplete, and exposed mainly in palatal view. Palatal bones are denticulate and the palatine has in addition a single large tooth. The basipterygoid process is laterally directed and the basipterygoid joint is open. The atlas carries large articulating facets for proatlantes, a pair of which are identifiable in one specimen. These features have not been found previously in a microsaur. All vertebral segments are dominated by a biconcave pleurocentrum; sutures between the pleurocentrum and neural arch are visible in presacral vertebrae. Distinctive microsaurian intercentra occur between all presacral pleurocentra. Their presence reinforces the hypothesis that microsaur intercentra are homologous with those of other early tetrapods. Caudal vertebrae retain separate haemal arches and some have ribs.Observed microsaur synapomorphies include: atlas with large median odontoid; atlas with concave lateral facets for occipital condyle; paired occipital condyles that are broad and concave; and thin, straplike intercentra. No observed features support a sister-group relationship with any other microsaur species, or placement within any higher level microsaur group. Because significant portions of the skeleton are missing or inaccessible, the Goreville microsaur is not formally named. A standardized, hierarchical format for skeletal characters is introduced that facilitates data sharing and comparison and fosters rapid archiving and retrieval.

Texte intégralRésumé :
Objective: The objective of this study was to evaluate the ability of the buccal fat pad flap (BFPF) to fill the void remaining after muscle transposition and study its effect on durability, fistula rate, palatal shortening/contraction, and relapse of muscle positioning in wide and challenging cleft repairs. Design: A retrospective chart review was performed. Charts were abstracted for standard demographics, reason for BFPF utilization, palatal length, palatal fistula, co-morbidities, and speech outcomes. Patients, Participants: Patients under age 3 who underwent primary palatoplasty between October 2007 and September 2015 which utilized a medially placed BFPF were identified. Results: Fifty-three patients were identified. Mean age at palatoplasty was 1.4 (0.78-2.55) years. Mean follow-up was 2.52 (0.02-7.26) years. Twenty-four (45.3%) patients had concerning intraoperative findings warranting flap utilization. Twenty-nine (54.7%) patients underwent BFPF for large dead-space volume. Four patients (7.55%) experienced a fistula. Thirty-nine patients had comments on their palatal length. Of these, 28 (71.8%) were of average length, and 8 (20.5%) were long. Thirty-three patients have undergone formal speech evaluation. Of these, 20 (60.6%) were of normal resonance, and 12 (36.4%) demonstrated nominal hypernasality. No patients have yet to require a secondary speech operation. Conclusion: Use of the BFPF has become more common in our practice particularly in challenging cleft palate repairs. It is a versatile technique addressing large interpositional dead space and thin outer and inner lamellae in the anterior soft palate after posterior muscle transposition. Early results, in difficult repairs, demonstrate excellent durability and that palatal length appears to be maintained, potentially lessening the need for secondary speech surgery.

Texte intégralRésumé :
A líquida palatal do português foi introduzida no sistema consonantal a partir de processos ocorridos durante a evolução do latim ao português, os quais, de acordo com Silva (2001), são decorrentes do fenômeno da palatalização. Para Matzenauer-Hernadorena (1994), do ponto de vista melódico, isto é, em termos segmentais, a líquida palatal tem uma estrutura complexa, pois apresenta duas articulações, uma primária, no ponto de consoante, e outra secundária, no nó vocálico. Considerando-se a complexidade da consoante, este estudo tem o objetivo de investigar o comportamento da líquida palatal, observando-se a diacronia e a aquisição da escrita. Para a composição do corpus da pesquisa foram analisados dados de escrita de crianças brasileiras e portuguesas pertencentes aos estratos 3 e 4 do BATALE – Banco de Textos de Aquisição da Linguagem Escrita. A amostra utilizada para análise dos processos envolvidos na diacronia das soantes palatais foi composta por dados extraídos de livros que tratam da evolução do latim ao português. Os resultados demonstraram que os processos verificados na diacronia e na aquisição da escrita ocorrem em direções opostas. Os resultados apontaram que há uma simplificação das consoantes complexas pelas crianças na aquisição da escrita enquanto ocorre o processo inverso na diacronia da líquida palatal.

<p>O objetivo deste artigo é apresentar e discutir alguns processos morfofonológicos que ocorrem em Mẽbêngôkre, envolvendo a sonorização das oclusivas surdas /p/, /t/ e /k/ em coda silábica, com apoio na Teoria da Otimalidade (PRINCE; SMOLENSKY, 1993), na Morfologia Prosódica (McCARTHY; PRINCE, 1993) e na Geometria de Traços (CLEMENTS; HUME, 1995). Os dados são provenientes de pesquisa de campo, obtidos por meio de gravações com três consultores indígenas da aldeia Moxkàràkô, localizada no município de São Félix do Xingu (PA) e foram transcritos no programa Transcriber. Posteriormente, foram selecionados os exemplos para o artigo, com a seguinte distribuição: Quatro ocorrências com a oclusiva surda [p]: seguida pela bilabial [m], pela palatal [ɲ], pela velar [ƞ] e pela alveolar [ɾ], em que [p] sonorizou em [m]. Quatro ocorrências com a oclusiva surda [t]: seguida pela bilabial [m], pela palatal [ɲ], pela velar [ƞ], e pela alveolar [ɾ], em que [t] sonorizou em [n]. Foram identificados também três ocorrências da oclusiva surda [k]: seguida pela nasal [m], em que [k] sonorizou em [m], seguida pela palatal [ɲ], em que [k] sonorizou em [ɲ] e, seguida pela velar [ŋ], em que [k] sonorizou em [ŋ]. A sonorização dos segmentos [p] → [m], [t] → [n] e [k] → [ɲ] serão mostrados em forma de árvore após a descrição destas ocorrências. Concluiu-se que a sonorização de oclusivas surdas em coda sofre influência tanto da vogal do núcleo da sílaba, quanto da consoante inicial da palavra subsequente.</p>

Texte intégralRésumé :
Abstract
This study aimed at modifying the method for obtaining an axial cut of the maxilla, considering the palatine anatomy, for evaluation of the maturation stage of the midpalatal suture (MPS) and to compare this modified method with the original one.The sample consisted of 84 cone-beam computed tomography (CBCT) scans of 40 boys and 44 girls, aged 11 to 15 years. The files were exported to the Nemotec Dental Studio program, which was used to obtain axial cuts of the maxilla so as to follow the palatine anatomy, keeping the buccal and nasal cortical bones centralized and equidistant. Two previously calibrated evaluators classified the axial images of the MPS into 5 maturational stages (A, B, C, D, and E) according to suture morphology. Kappa test was used to test intra and inter-examiner agreement and the sign test was used to compare the results of this study with those from the original method. Statistical significance level was set at 0.05%. The kappa values for intra and inter-examiner agreement were 0.88 and 0.69, respectively. The modified method was able to evaluate the MPS maturation status and could demonstrate stages of maturation in more detail than the original method. Classification of the MPS maturation with the curved suture axial cut of this method is similar to the original method, with the advantage of allowing evaluation of maturation in the midline of the palate, even when the palate was curved and/or thick.
Keywords: Sutures. Maxilla. Palatal Expansion Technique.
Resumo
Este estudo visou modificar o método para a obtenção de um corte axial da maxila, considerando a anatomia do palato, para avaliação da maturação da sutura palatina (SPM) e para comparar este método modificado com o original. A amostra foi composta de 84 tomografias computadorizadas (TCFC) de 40 meninos e 44 meninas, com idades entre 11 a 15 anos. Os arquivos foram exportados para o programa Nemotec Dental Studio, que foi usado para obter cortes axiais da maxila de modo a acompanhar a anatomia do palato, mantendo a cortical óssea vestibular e nasal centralizada e equidistante. Dois avaliadores previamente calibrados, classificaram as imagens axiais da SPM em 5 fases de maturação (A, B, C, D, e E) de acordo com a morfologia da sutura. O Teste Kappa foi usado para testar concordância intra e inter-examinador e o teste do sinal foi utilizado para comparar os resultados deste estudo com os do método original. O nível de significância estatística foi de 0,05%. Os valores de kappa para concordância intra e inter-examinador foram 0,88 e 0,69, respectivamente. O método modificado foi capaz de avaliar o estágio de maturação da SPM e pode demonstrar estágios de maturação em mais detalhe do que o método original. A classificação da maturação da SPM com o corte axial curvo deste método é semelhante ao método original, com a vantagem de permitir a avaliação da maturação na linha média do palato, mesmo quando o palato for curvo e/ou espesso.

São inquestionáveis as vantagens do leite materno para o neonato. Na sua impossibilidade, é necessária a introdução do leite artificial e de alimentação adequada como forma de reposição de nutrientes, respeitando-se a maturação neuro-fisiológica da criança. Para o estudo, foram investigadas 60 crianças de 2 a 4 anos, de ambos os sexos, portadoras de lesão lábio-palatal, pacientes do Hospital de Reabilitação de Anomalias Craniofaciais, Universidade de São Paulo, Bauru, quanto a sua história dietética pregressa (aleitamento e introdução alimentar) e peso e estatura atuais, a fim de verificar possíveis influências no estado nutricional relacionadas à sua alimentação no primeiro ano de vida. Os dados obtidos mostraram que o aleitamento materno foi significativo, e que o desmame, o aleitamento artificial e a introdução alimentar, apesar de inadequados, pouco influenciaram na antropometria atual.

Texte intégralRésumé :
Abstract
The aim of this study was to define distinct craniofacial features in subjects with nonsyndromic cleft lip and palate (CLP) and in subjects with Turner syndrome (TS), and to evaluate the resemblance of these features among their family members. This might help in elucidating if there is a parental contribution to possible predisposing craniofacial features in cleft subjects and to the severity of certain distinct craniofacial features in subjects with X chromosome monosomy.
The study population consisted of 29 Costa Rican CLP families including unaffected parents and siblings, and of 71 TS (45,X) subjects and members of their families. Based on lateral and frontal cephalometric analyses, cleft family members were characterized by reduced cranial height and head width, greater interorbital and nasal cavity widths, shorter anterior cranial base and palatal lengths, and shorter total face height compared to control values. With respect to these distinct craniofacial features, there were statistically significant associations in anterior cranial base and palatal length, and head, forehead and outer interorbital width measurements between parents and their children with CLP. The sidedness of the cleft in affected children was related to the asymmetry of the nasal cavity width in their parents. The distinct craniofacial features of the TS subjects, such as short clivus, retrognathic position of mandible, and narrow maxilla at the level of first premolars were related to their mothers' corresponding features. The presence of lateral palatine ridges, which were detected in one third of the TS subjects, was related to the narrowness of the posterior palate rather than to the variation in the tongue position.
Distinct craniofacial features segregate in cleft family members. The several significant associations in distinct craniofacial dimensions between parents and children with CLP emphasize the importance of genetic factors in the genesis of nonsyndromic orofacial clefting. The present results support the concept that maternal factors contribute to the degree of deficiency in the growth of the cranial base and to the magnitude of mandibular retrognathism of their daughters with TS. Maternal influences may also modify the width of the palate in TS.

Texte intégralRésumé :
Unilateral cleft lip and palate (UCLP) is a craniofacial malformation with functional and aesthetical impact on the face and the upper airways. The aims of the current thesis were to evaluate Quality of life (QoL) in adults treated for UCLP (I), to objectively evaluate nasal form and function and to search for possible differences in residual nasal deformity and impairment of function between patients operated according to one-stage and two-stage palate closure (II) as well as to evaluate the relationship between professional and lay rating and patient satisfaction with nasolabial appearance (III) and to identify factors associated with lower levels of QoL and less satisfaction with nasal appearance among adults treated for UCLP (IV). Analyses of data from a homogenous population of UCLP patients treated at Uppsala University Hospital form the basis of this thesis. The mean follow-up time after primary surgery was 35 years (20-47 years) and participation rate was 79% (n=86). An age and gender matched control group of 68 people without clefts were evaluated according to the same protocol. The evaluation protocol included the Short Form 36 questionnaire (SF-36), rhinomanometry, acoustic rhinometry, odor test, peak nasal inspiratory flow test and photographies of faces. For the SF-36 data, age- and gender-matched norm data of 1385 people from the Swedish population were used. Unilateral cleft lip and palate affected QoL differently depending on gender and age of the patient. Younger patients were affected more negatively than older patients in several subscales. However, except for lower values in the Mental Health subscale, QoL was similar among UCLP patients and norm data. Objectively measured nasal function was extensively affected among adults treated for UCLP. No difference in impairment of nasal function was found between one-stage and two-stage palate closure protocols on the cleft side. Judgment of nasolabial appearance differed between professionals, lay people and patients. Large infant cleft width was associated with less satisfaction with nasal appearance and male gender was associated with lower levels of mental QoL. Correlation between high nasal breathing resistance and low levels of physical QoL was found. In conclusion, this thesis provides a platform for future research for optimal evaluation of cleft treatment outcome.

Texte intégralRésumé :
Objetivo: Os indivíduos com fissura labiopalatina vivenciam um desequilíbrio morfofuncional desde a vida intrauterina influenciando o crescimento craniofacial e o desempenho das funções orais. O objetivo deste estudo foi avaliar a força e a mobilidade da língua em indivíduos com fissura labiopalatina operada, bem como de um grupo controle formado por indivíduos sem esta malformação e com boa relação dento-oclusal, para verificar a relação entre a força e a mobilidade da língua; a relação entre a força da língua e as funções de respiração, mastigação, deglutição e fala; assim como a diferença quanto a força e a mobilidade da língua entre os grupos. Método: Após aprovação do Comitê de Ética em Pesquisa, foram avaliados 59 indivíduos com idade entre 18 e 28 anos (média=23 anos e 3 meses), de ambos os gêneros, 30 com fissura unilateral completa de lábio e palato reparada e 29 com boa relação dento-oclusal, sem fissura labiopalatina e outras malformações. Foi realizado o exame miofuncional orofacial (MBGR) para verificar a mobilidade da língua e as funções de respiração, mastigação, deglutição e fala. Imagens do exame foram registradas e analisadas por três examinadores, com boa concordância entre eles verificada pela medida Kappa. O exame da força da língua utilizou o instrumento Iowa Oral Performance Instrument (IOPI) nas provas de elevação, lateralização para a direita e para a esquerda e protrusão da língua, além do teste de resistência. As correlações entre a força e a mobilidade da língua e, entre a força da língua e as funções de respiração, mastigação, deglutição e fala foram estabelecidas pelo Coeficiente de Correlação de Spearman, já a diferença quanto a força e a mobilidade da língua entre os grupos foi verificada pelo teste de Mann-Whitney. Resultados e Conclusão: Na amostra estudada, a relação significativa entre a força e a mobilidade da língua, bem como entre a força da língua e as funções de respiração, mastigação, deglutição e fala não foi verificada. Já a força e a mobilidade da língua foram menores para o grupo estudo.Objective: Cleft lip and palate individuals experienced a morphofunctional imbalance since intrauterine life influencing on craniofacial growth and oral function performance. This study aimed to evaluate the tongue strength and mobility of these individuals compared with those of a control group without cleft lip and palate and with good occlusal relationship, to verify the relationship between tongue strength and mobility; tongue strength and the functions of breathing, mastication, swallowing, and speech; as well as the difference between groups in the strength and tongue mobility. Method: After the approval of the Ethical Committee in Research, 59 individuals aged between 18 and 28 years (mean=23 years and 3 months), both genders, were evaluated comprising 30 individuals with repaired complete cleft lip and palate and 29 individuals with good occlusal relationship and without cleft lip and palate and other malformations. The orofacial myofunctional evaluation (MBGR) was conducted to verify the tongue mobility and the functions of breathing, mastication, swallowing, and speech. The images of the evaluation were recorded and analyzed by three examiners with good agreement among them verified by Kappa test. The evaluation of the tongue strength used the Iowa Oral Performance Instrument (IOPI) during the elevation, left and right lateralization and protrusion of the tongue and endurance test. The correlations between the tongue strength and mobility, and among tongue strength and the functions of breathing, mastication, swallowing, and speech were established by Spearman Correlation Coefficient, already the difference in the tongue strength and mobility between groups were assessed by the Mann-Whitney test. Results and Conclusion: In the studied sample, the significant relationship between tongue strength and mobility and among tongue strength and the functions of breathing, mastication, swallowing, and speech was not verified. However the tongue strength and mobility were lower in the study group.

Texte intégralRésumé :
Objetivo: Avaliar a força de mordida (FM) em crianças com fissura labiopalatina (FLP) reparada. Material e Métodos: Cento e cinquenta crianças, com idade entre 6-12 anos, com e sem FLP, foram divididos em 5 grupos: 1) grupo controle (CON) : 34 crianças sem FLP; 2) grupo com fissura pré-forame incisivo (FPré): 31 crianças com fissura envolvendo o pré-maxila; 3) grupo FLP transforame incisivo unilateral (FTU): 36 crianças com FLP transforame incisivo unilateral completa; 4) grupo FLP transforame incisivo bilateral (FTB): 32 crianças com FLP transforame incisivo bilateral completa; e 5) grupo fissura pós-forame incisivo (FPós): 17 crianças com fissura pós-forame incisivo completa. A FM, expressa em Kgf, foi avaliada por meio de gnatodinamômetro (IDDK, Kratos, Cotia, SP, Brasil). Foram feitas 3 medidas consecutivas, com um intervalo de 1 minuto entre elas, para evitar a fadiga do voluntário. A medida mais elevada foi considerada para análise. Para os grupos CON, FTB, FPré e FPós, a FM foi obtida na região anterior e posterior da maxila. Para o grupo FTU, FM foi avaliada nas regiões anterior e posterior de ambos os segmentos, a fim de se distinguir os valores de FM em regiões diferentemente afetadas pela presença da fissura. As diferenças entre os grupos foram avaliadas através do teste ANOVA de medidas repetidas. O teste de Tukey foi utilizado para aferir correlação entre as variáveis. Para a correlação entre FM e idade, foi utilizado o teste de Correlação de Pearson. Em todos os casos, foram considerados significativos valores de p<0.05. Resultados: Não foram encontradas diferenças significativas entre a FM posterior do grupo CON (30,7±9,2) e dos grupos FPré (35,3±11,6), FTU (lado fissurado: 26,5±10,7 e lado não-fissurado: 29,6±10,0), FTB (25,6±5,9) e FPós (29,1±12,0). Entretanto, valores de FM significantemente maiores foram observados no grupo FPré, quando comparado a FTU e FTB. Não foram observadas diferenças significantes entre o lado fissurado e não fissurado do grupo FTU. Finalmente, em todos os grupos, os valores de FM da região anterior da maxila foram menores, quando comparados à região posterior. Conclusão: Neste trabalho os valores de FM em crianças com FLP foram equivalentes àqueles encontrados em crianças sem essa anomalia.Objective: To assess the bite force (BF) of children with repaired cleft lip and palate (CLP) Design: One hundred and fifty children, aged 6-12 years, with and without CLP, were divided into the following 5 groups: 1) control group (CON): 34 children without CLP; 2) cleft lip group (CL): 31 children with cleft lip involving the pre-maxilla; 3) unilateral CLP group (UCLP): 36 children with complete unilateral CLP; 4) bilateral CLP group (BCLP): 32 children with complete bilateral CLP; and 5) cleft palate group (CP): 17 children with complete cleft palate. BF, expressed in Kgf, was assessed with a gnathodynamometer (IDDK, Kratos, Cotia, SP, Brazil), before alveolar bone grafting. For CON, BCLP, CL and CP groups, BF was obtained in the anterior and posterior region of the maxilla. For the UCLP group, BF was assessed in the anterior and posterior regions of both segments. Differences among groups were evaluated by ANOVA test, and Tukeys test was used to assess any correlations among variables. Correlation between BF and age were assessed using Pearson Product-Moment Correlation. In all cases, values of p < 0.05 were considered for analysis. Results: Contrary to what was expected, no differences of posterior BF were observed among CON group (30.7 ± 9.2) and CL (35.3 ± 11.6), UCLP (cleft side: 26.5 ± 10, 7 and noncleft side: 29.6 ± 10.0), BCLP (25.6 ± 5.9) and CP (29.1 ± 12.0) groups. However, a stronger BF was observed in the CL group when compared to the UCLP and BCLP groups. Next, no differences were observed between the cleft side and the noncleft side in the UCLP group. Lastly, in all groups, BFs from the anterior region of the maxilla were less when compared to the posterior regions. Conclusion: The BF of children with CLP is no different from children without CLP.

Texte intégralRésumé :
As fissuras palatinas além de envolvem o osso alveolar podem promover a ausência do dente incisivo lateral ou apresenta-lo severamente comprometido. Nesses casos sua reabilitação poderá ser feita por próteses parciais fixas convencionais ou por prótese sobre implantes, geralmente após uma cirurgia de enxerto ósseo na região. Todavia além da estética, se faz necessário investigar sobre o potencial de força oclusal que essas reabilitações proporcionam. Assim, o propósito desse estudo foi avaliar a força máxima de mordida em indivíduos com fissura labiopalatina unilateral reabilitados com prótese parcial fixa convencional e sobre implantes e comparar esses resultados com o lado contralateral e com indivíduos sem fissura. A amostra foi constituída por 50 indivíduos, 25 pacientes com fissura (15 reabilitados com próteses parciais fixas convencionais e 10 sobre implantes) e 25 indivíduos sem fissura com dentes naturais. A força de mordida máxima foi mensurada por um único examinador utilizando o gnatodinamômetro, registrado nas regiões reabilitadas de incisivo lateral e canino, região de molares e incisivos centrais. Os valores médios obtidos, e a análise estatística com os testes t de Student e t de Student pareado permitiram observar que no mesmo indivíduo, a força de mordida do lado não afetado foi estatisticamente superior quando comparado com o lado da fissura reabilitado com prótese (p=0,005). O grupo reabilitado com prótese fixa convencional apresentou a força máxima de mordida estatisticamente igual ao grupo com prótese fixa sobre implante (p=0,781). Considerando os grupos experimental e controle na região de molares os resultados foram estatisticamente iguais (lado afetado p=0,082 e não afetado p=0,066). Na região de incisivo lateral e canino, o lado correspondente ao afetado no grupo-controle, apresentou força máxima de mordida estatisticamente maior que o grupo-experimental (p=0,004), enquanto no lado correspondente ao não afetado os resultados foram iguais. Na região de incisivos centrais o resultado médio do grupo-controle também foi estatisticamente maior que o experimental (p=0,005)The cleft palate involving the alveolar bone may have the lateral incisor tooth missing or severely compromised. In such cases rehabilitation can be done through fixed dental prostheses or implant-supported fixed dental prostheses, generally after a bone graft surgery in the region. However, beyond aesthetics, it is necessary to investigate the potential for occlusal force that these rehabilitations provide. Thus, the purpose of this study was to evaluate the maximum bite force in subjects with unilateral cleft lip and palate rehabilitated with fixed dental prostheses or implantsupported fixed dental prostheses and compare the results with the contralateral side and with individuals without cleft. The sample consisted of 50 subjects, 25 patients with cleft (15 rehabilitated with fixed dental prostheses and 10 with implant-supported fixed dental prostheses) and 25 individuals without cleft and with natural teeth. The maximum bite force was measured by means of gnathodynamometer, registered in the rehabilitated lateral incisor and canine region, molars region and incisors regions by a single examiner. The obtained average values, and the statistical analysis with the Student t test and paired Student t test allowed to be observed that on the same individual the bite force on the side that was not affected was statistically superior when compared to the side of the rehabilitated cleft with prosthesis (p=0,005). The rehabilitated group with conventional prostheses presented maximum bite force statistically equal to the group with the implant-supported fixed dental prostheses (p=0,781). Considering the experimental and control groups on the molar regions, the results were statistically equal (affected side p=0,082 e non-affected p=0,066). The lateral incisor and canine region from the correspondent affected side on the control group presented maximum bite force statistically higher than the experimental group (p=0,004), on the non-affected side the results were the same. In the incisor region, the average result of the control group was also statistically higher than the experimental group (p=0,005)

Texte intégralRésumé :
This research aimed at assessing respiratory muscle function, electrical activity of the accessory inspiratory muscles, diaphragmatic range of movement (DROM), the palate dimensions and nasal patency in adults with mouth breathing mode (MB), comparing with adults with nasal breathing mode (NB). In the study, 77 adults were selected, from 18 to 30 years old, of both sexes, according the inclusion criteria, allocated in MB (n=38) and NB (n=39) groups. The breathing mode (MB/NB) was diagnosed, based on physical characteristics, the signs and symptoms and on the otorhinolaryngologic examination. It was evaluated anthropometric measurements, maximal inspiratory and expiratory pressures (MIP, MEP), peak nasal inspiratory flow (PNIF), spirometry, nasal obstruction symptoms (NOSE scale), vertical and transverse palate dimensions , ultrasonography of the diaphragm muscle during breathing at Tidal Volume (TV), inspiration at Lung Total Capaciy (LTC) and sniff test. Yet, it was carried out the surface electromyographic (sEMG) of the sternocleidomastoid (SCM) and upper trapezius (UT) for evaluation of the amplitude and symmetry activity (POC%) during rest, inspiration at LTC and in the sniff, MIP and MEP tests. For statistical analysis, SPSS statistical software (version 17.0) was utilized, adopting a significance level of 5 % and the tests Shapiro-Wilk (data normality), Student t and Mann-Whitney (comparison between groups), Intraclass Correlation Coefficient (inter and intra-examiner reproducibility), Pearson and Spearman (correlation between variables) and the chi-square test for nominal variables. In the comparison between groups, the MB had significantly higher mean values for NOSE scale and lower mean values for MIP, MEP, PNIF, forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and sEMG activity of SCM in the sniff, PNIF and MIP tests. There was no difference in sEMG activity during rest, inspiration TLC, as well as for the POC%. The DROM was lower in the MB group in all tests, with significant difference at rest and TLC. Palate dimensions, in the MB group, showed significantly smaller transverse distance in intercanine region and, bigger in the vertical distance at the premolars and molars regions. The PNIF correlated inversely with the NOSE scale, with the UT sEMG at rest and LTC and, positively, with the FVC, the palate transversal distance, MIP and DROM. The MIP was positively correlated with MEP and FVC. The MB group presented smaller nasal patency, smaller width and higher height of hard palate than NB. The mouth breathing reflected in the smaller values of respiratory pressures, accessory inspiratory muscle electrical activity and diaphragmatic amplitude. As smaller the nasal patency, smaller the respiratory muscle pressure, the diaphragm amplitude and the width of hard palate.Esta pesquisa teve por objetivo verificar a função muscular respiratória, atividade elétrica dos músculos inspiratórios acessórios, amplitude do movimento diafragmático (AMD), dimensões do palato e patência nasal em adultos com modo respiratório oral (RO), comparando-os com adultos com modo respiratório nasal (RN). Foram selecionados 77 adultos, entre 18 e 30 anos de idade, de ambos os sexos, de acordo com os critérios de inclusão, sendo alocados nos grupos RO (n=38) e RN (n=39). O modo respiratório foi diagnosticado baseado nas características físicas, sinais e sintomas e no exame otorrinolaringológico. Avaliou-se medidas antropométricas, pressões inspiratórias e expiratórias máximas (PImáx, PEmáx), pico de fluxo inspiratório nasal (PFIN), espirometria, sintomatologia de obstrução nasal (escala NOSE), dimensões vertical e transversal do palato e ultrassonografia do diafragma durante respiração em volume corrente (VC), inspiração na capacidade pulmonar total (CPT) e teste de sniff. Ainda, realizou-se eletromiografia de superfície (sEMG) dos músculos esternocleidomastoideo (ECM) e trapézio superior (TS), para avaliação da amplitude e índice de simetria da atividade elétrica (POC%) no repouso, inspiração na CPT, sniff, PImáx e PFIN. Para a análise estatística utilizou-se o programa estatístico SPSS (versão 17.0), com nível de significância de 5% e os testes Shapiro-Wilk (normalidade dos dados), t-student e Mann-Whitney (comparação entre os grupos), Coeficiente de Correlação Intraclasse (reprodutibilidade inter e intra-examinadores), Pearson e Spearman (correlação entre as variáveis) e o qui-quadrado (variáveis nominais). Na comparação entre os grupos, os RO apresentaram valores significativamente maiores para a escala NOSE e menores para PImáx, PEmáx, PFIN, capacidade vital forçada (CVF), volume expiratório forçado no primeiro segundo (VEF1) e amplitude da sEMG dos músculos ECM nos testes de sniff, PFIN e PImáx. Não houve diferença na sEMG no repouso e na inspiração em CPT, assim como no POC%. A AMD foi menor no grupo RO em todas as situações testadas, com diferença significante durante o repouso e CPT. O grupo RO apresentou distância transversal do palato significativamente menor na região intercanina e maior na distância vertical, na região dos pré-molares e molares. A medida do PFIN se correlacionou inversamente com a escala NOSE e com a sEMG do TS durante o repouso e CPT. Correlações positivas foram encontradas na medida do PFIN com CVF, distância transversal do palato, PImáx e AMD. A PImáx se correlacionou positivamente com a PEmáx e CVF. O grupo RO apresentou menor patência nasal, menor largura e maior altura do palato duro que o RN. A respiração oral repercutiu em menores valores de pressões respiratórias, de atividade elétrica dos músculos inspiratórios acessórios e de amplitude diafragmática. Quanto menor a patência nasal, menores os valores das pressões respiratórias, a amplitude de movimento do diafragma e a largura do palato duro.

Texte intégralRésumé :
OGGETTO: Valutare attraverso l’uso delle tecniche della geometria morfometrica il pattern di covarianza tra la morfologia palatale e craniofacciale.
MATERIALI E METODI: è stato raccolto un campione di 85 soggetti (44F,41M;età media 8.7±0.8) con malocclusione di II Classe secondo questi criteri di inclusione: etnia caucasica, II Classe scheletrica, rapporti occlusali di II Classe divisione 1 secondo Angle, fase della dentatura mista precoce, stadio prepuberale di crescita scheletrica. Per ogni soggetto sono stati raccolti modelli in gesso e teleradiografie del cranio in proiezione latero-laterale dell’epoca pretrattamento. È stata applicata l’analisi di Procruste e poi effettuata l’analisi delle componenti principali (PCA) per mettere in luce il pattern di variazione morfologica palatale e quello craniofacciale. Successivamente è stata condotta l’analisi dei minimi quadrati parziali per stabilire se ci fosse un pattern di covarianza tra la morfologia palatale e craniofacciale.
RISULTATI: per quanto riguarda la morfologia palatale la prima componente principale si riferisce a cambiamenti spaziali nelle tre dimensioni. Per quanto riguarda invece la morfologia craniofacciale la prima componente principale riguarda variazioni morfologiche sul piano scheletrico verticale. La morfologia del palato e del complesso scheletrico craniofacciale covaria significativamente. La componente principale PLS1 riguarda circa il 64% della covarianza totale e correla la divergenza facciale alla larghezza e all’altezza della volta palatina; quanto più il pattern di crescita craniofacciale tende all’iperdivergenza tanto più stretto e alto sarà il palato.
CONCLUSIONI: i soggetti con malocclusione di II Classe con pattern scheletrico craniofacciale iperdivergente tendono ad avere un palato stretto dalla volta alta mentre i soggetti con caratteristiche scheletriche di ipodivergenza hanno tendenzialmente un palato più basso e largo.

Texte intégralRésumé :
Background: Several treatment protocols exist for the management of patients with complete unilateral (CUCLP) and bilateral (CBCLP) cleft lip and palate, and little evidence exists on comparison of their outcomes. Objectives: To compare craniofacial morphology among individuals with CUCLP and CBCLP treated at different North American centers. Methods: Lateral cephalograms of 148 individuals with repaired CUCLP (average age = 8y 8m) and 93 individuals with repaired CBCLP (average age = 8y 10m) were analyzed. The group means for the different centers per cephalometric measurement evaluated (16 angular, 7 linear, and 2 ratio), were compared using ANOVA. Results: For both the CUCLP and CBCLP samples, the most significant differences were observed in the sagittal maxillary prominence. The center that performed primary alveolar bone grafting consistently showed the lowest maxillary prominence. Conclusions: Significant differences in craniofacial morphology, specifically maxillary prominence, exist among patients with CUCLP and CBCLP treated at different North American centers.

Texte intégralRésumé :
This monograph presents a thorough investigation of the main historical and present-day variation and change patterns undergone by palatal sounds in the Romance languages. By relying on phonetic and phonological information to motivate a formal account of palatal sound change, the analyses proposed in this book offer a principled, constraint-based explanation for the evolution of palatals in the Romance-speaking world. It provides a robust and up-to-date literature review on the subject, taking into consideration not only the viewpoints and data from diachronic research, but also the results from various phonetic, phonological, dialectal, and comprehensive studies. By taking into account the role of phonetic information in the shaping of phonological patterns, this book approaches sound change from its inception during the speaker-listener interaction and formalizes it as the difference in constraint ranking between the grammar of the speaker and that of the listener-turned-speaker. This perspective is intended to model how and why similar change events may take place in different varieties and/or the same language across periods of time.

Texte intégralRésumé :
This chapter concerns Batesian mimicry, which is the resemblance of a palatable species to an unpalatable or otherwise unprofitable species. Often these unprofitable models have warning signals, which the mimic has evolved to copy. The chapter also considers another well-known form of deception, namely masquerade, which is the resemblance of a palatable species to the cues of an object of no inherent interest to a potential predator such as leaves, thorns, sticks, stones, or bird droppings. Batesian mimicry and masquerade share many properties, and both can be considered examples of ‘protective deceptive mimicry’. We begin by briefly reviewing some well-known examples of protective deceptive mimicry. We then compare and contrast the various theories that have been proposed to understand them. Next, we examine the evidence for the phenomenon and its predicted properties, and finally we address several important questions and controversies, many of which remain only partly resolved.

Texte intégralRésumé :
This chapter surveys the limited evidence on Islamic palatial architecture in the Western Mediterranean during the Early Modern Period. Northern Africa was weakly incorporated into the Ottoman Empire as the Barbary States. In the capital cities– Tripoli, Tunis and Algiers – leaders took on the trappings of traditional Islamic rulers and preserved the earlier architectural styles and concepts of space in their palace designs. In Morocco a succession of Berber and Arab dynasties resisted the Ottomans and united the far-western Maghreb. These rulers underpinned their rule by religious ideology and built huge palatial cities featuring a diversity of architectural forms at the “royal cities” (Fes, Marrakesh, Rabat and Méknes) – though, for the most part, the chief typologies and spatial concepts were developed in previous centuries. Towards the end of the period, the growing influence of European colonialism brought an end to the tradition of Islamic architecture in both regions.

Texte intégralRésumé :
Cancers of the oral cavity, oropharynx, lip, and salivary glands are malignancies of the head and neck. Some of these cancer sites share risk factors, although each has distinctive anatomic, epidemiologic, and clinical features. Oral cavity cancers arise on the inner lip and buccal mucosa, anterior two-thirds of the tongue, gum, hard palate, and floor of mouth. These cancers are strongly associated with the use of smoked and smokeless tobacco products, heavy alcohol consumption, and chewing of betel quid or pan, but only minimally associated with prior infection with human papillomavirus (HPV). In contrast, oropharyngeal cancers affect the posterior one-third (base) of the tongue, tonsils, soft palate, and other oropharyngeal tissues and are strongly associated with HPV-16 infection as well as with the use of tobacco, alcohol, and betel quid. In principle, tumors of the oral cavity, oropharynx, and lip are among the most preventable forms of cancer.

Texte intégralRésumé :
Despite public favorability towards international non-governmental organizations (INGOs), most of these groups toil in total obscurity. A very few INGOs, active in human rights promotion, humanitarian relief, and environmental protection, do secure widespread authority in the form of deference from multiple audiences engaged in global politics. Having achieved this status as a “leading INGO,” however, they are trapped. To maintain their status and placate their many audiences, these leading INGOs advance incrementalist proposals and achieve “vanilla victories” - palatable to a wide array of audiences, but also unremarkable. Meanwhile, other INGOs’ strategies are similarly shaped by their status: they are free to issue harsh condemnations and advance radical proposals, but these generally get ignored. Stroup and Wong offer the first exploration of the vast differences among INGOs in their authority, and then explore how status shapes INGO strategies as they seek to influence states, corporations, and one another.

Texte intégralRésumé :
This chapter covers the spectrum of routine monitoring, audit, service evaluation, and formal research. Routine monitoring is an essential task for all mental health professionals, and techniques to make it more palatable are explored, including using routine data for clinical supervision and monitoring team targets. Regular audit is described as an essential tool for logical service development and quality improvement. In the discussion of research, the importance of choosing the correct methodology and of paying attention to detail are stressed. In community psychiatry, sampling bias, regression to the mean, and the Hawthorne effect pose important risks. The hierarchy of research methods is outlined with randomized controlled trials (RCTs) at the top, preferably with either single- or double-blinding. Careful statistics and systematic reviews support evidence-based practice. In addition to experimental quantitative trials, there is a place for cohort and case control trials, as well as for qualitative trials to generate hypotheses.

Texte intégralRésumé :
Caning (or Shatt), an Eastern Sudanic (Nilo-Saharan) language of Sudan, has bilabial, alveolar, palatal, and velar plosives, but it is not straightforward for which plosives (if any) there is an underlying voicing contrast. Three analyses that can be shown to account reasonably for the data. One analysis proposes a voicing contrast of all plosives in all word positions where plosives occur. Of the three, this analysis posits underlying plosives most closely to the surface forms. A second analysis proposes only a voicing contrast of alveolar and velar plosives in word-initial position, and posits the same alternation processes in roots that are observed across morpheme boundaries. A third analysis proposes no voicing contrast of any plosives in any position by positing a “ghost” consonant before alveolar and velar plosives in word-initial position. There are advantages to each analysis, but none is without certain obstacles. After the noun root and morphological data of plosives is presented as neutrally as possible, the data are analyzed according to each of the three competing analyses, and the evidence for each is summarized. The reader is left to decide which analysis is the best choice.

Texte intégralRésumé :
Colombia is in a privileged position to take advantage of international climate agreements to finance sustainable development initiatives. The country is a signatory of the United Nations Framework Convention on Climate Change (UNFCCC), the Kyoto Protocol, and the Paris Agreements. As a non-Annex I party to the UNFCCC, Colombia produces low emissions in relation to global numbers (0.46% of total global emissions for 2010) and exhibits biogeographical conditions that are ideal for mitigation of climate change through greenhouse gas sequestration and emission reductions. Simultaneously, recent extreme climatic events have harshly compromised the country’s economy, making Colombia’s vulnerability to climate change evident.While these conditions should justify a strong approach to climate change communication that motivates decision making and leads to mitigation and adaptation, the majority of sectors still fall short of effectively communicating their climate change messages. Official information about climate change is often too technical and rarely includes a call for action. However, a few exceptions exist, including environmental education materials for children and a noteworthy recent strategy to deliver the Third Communication to the UNFCCC in a form that is more palatable to the general public. Despite strong research on climate change, particularly related to agricultural, environmental, and earth sciences, academic products are rarely communicated in a way that is easily understood by decision makers and has a clear impact on public policy. Messages from the mass media frequently confuse rather than inform the public. For instance, television news refers to weather-related disasters, climate variability, and climate change indiscriminately. This shapes an erroneous idea of climate change among the public and weakens the effectiveness of communications on the issue.The authors contrast the practices of these sectors with those of nongovernmental organizations (NGOs) working in Colombia to show how they address the specific climate communication needs facing the country. These NGOs directly face the challenge of working with diverse population groups in this multicultural, multiethnic, and megadiverse country. NGOs customize languages, channels, and messages for different audiences and contexts, with the ultimate goal of building capacity in local communities, influencing policymakers, and sensitizing the private sector. Strategies that result from the work of interdisciplinary groups, involve feedback from the audiences, and incorporate adaptive management have proven to be particularly effective.

Chapter 15 argues that the Seleucids selectively appropriated the Persian palatial traditions to subsume and supersede the Achaemenid legacy. It argues that the Seleucids also used select Achaemenid palaces as anti-monuments, particularly, Susa. The chapter establishes that contours of Seleucid palatial architecture in Iran from the available evidence. It then tracks how the Arsacids engaged the Seleucid palatial tradition before creating new architecture forms with lasting effects on the Iranian. Namely, domed and vaulted architecture.

Texte intégralRésumé :
In Chapter 21, we described the development of the pharyngeal arches and their derivatives. Craniofacial abnormalities account for about one third of all live birth defects. These arise during the development of the pharyngeal arches described in Chapter 21 or during the events described in this chapter. The first pharyngeal arch, the mandibular arch, is one of the basic building blocks needed to form the face and associated structures. The other major building block is the frontonasal process that covers the developing forebrain. The development of the face begins after the first pharyngeal arch forms around four weeks post-fertilization. At this stage, the head consists of a large bulge over the developing forebrain, approximating to the forehead and the mandibular arch in the position of the lower jaw. A slit between the frontonasal process and mandibular arch is continuous with the foregut tube; this slit is the primitive oral cavity or stomodeum. This primitive mouth cavity has no side walls where the cheeks would be and more significantly, there is no nasal cavity. Development of the nasal and oral cavities internally and the face externally proceeds at the same time over the course of the next eight weeks of development. Essentially, the nasal cavity is formed, then divided into two and separated from the oral cavity by the palate. The sequence of events is: • Development of the nasal cavity and first part of the palate, beginning the separation the oral and nasal cavities; • Development of the maxillary arch from the mandibular arch to form the cheeks and important structures contributing to the palate; • Completion of the components required to form the palate and separate the nasal cavity into right and left cavities; • Fusion of the building blocks to complete the separation of the nasal cavity and the separation of the nasal cavity from the oral cavity. As you can see in Figure 32.1A, the stomodeum is roofed by the frontonasal process and its floor is the fused mandibular arches.

Texte intégralRésumé :
Using evidence from the extensive cemeteries at the palatial center of Mycenae and at Prosymna, a second tier settlement site within the territory of Mycenae, this chapter examines the burial practices, patterns, and traditions within the sociopolitical context of the Palatial period itself, but also with a longer diachronic lens toward what came before and what follows. In the form and scale of burial architecture, in the treatment of interments, and among the objects associated with burial practices, significant changes occur. During the period of state formation, tomb architecture and burial practices exhibit diverse and potentially competitive characteristics. The variety of exotica and specialized ceramic sets suggest conspicuous consumption and differential access to status as much as do the weapons and jewelry in valuable materials. A sociopolitical flourishing comes with the Palatial period. While there is great expansion in the numbers of tombs, at the same time the patterns of use both stabilize and standardize. Remarkable at both sites is a pronounced contraction of investment in the mortuary sphere when the Palatial period is at its height—burial traditions are simplified and streamlined including characteristics from constructional details down to a marked decline in grave provisions, especially among higher value and status materials and exotica. This previews by several generations the characteristics of the Postpalatial period, when a dramatic decline in material culture generally is reflected also in tomb construction and use.

Texte intégralRésumé :
This chapter provides a phonetically based formal account of the diachronic and synchronic sound changes discussed in previous chapters, following the phonetic characterization of palatal sounds and the book’s theoretical assumptions. Specifically, the speaker-listener interaction and the constraint-based model adopted in this book provide the tools to put forth a unified proposal that not only models how and why most of the discussed sound changes could emerge in the first place, but also reveals the mechanisms through which similar change events may reoccur time and again across Romance varieties.

Texte intégralRésumé :
The chapter deals with the origin and phonetic causes of sound changes involving consonants, with the diachronic pathways connecting the input and output phonetic forms, and with models of sound change (e.g., Evolutionary Phonology, the Neogrammarian’s articulatory model, Ohala’s acoustic equivalence model). The need to use articulatory and acoustic data for ascertaining the causes of sound change (and in particular the palatalization and assibilation of velar, labial, and dentoalveolar obstruents) is emphasized. The chapter is also concerned with how allophones are phonologized in sound-change processes and with the special status of (alveolo)palatal stops regarding allophonic phonologization.

Texte intégralRésumé :
This chapter discusses Edmund Spenser's experiments with interwoven rhyme patterns in Amoretti (1595). Writing at the height of the late Elizabethan sonnet craze, Spenser tests the conventional limits of the genre and interrogates the political implications of its dedication to the solitary individual. In his sonnet sequence celebrating his betrothal to Elizabeth Boyle, Spenser depicts the drama of courtship as a small-scale version of the struggle to unite freeborn individuals in communities. Pointing to his interwoven rhyme schemes and the sonnet form itself as emblems of pleasant and beneficial confinement, he argues that social life requires a form of voluntary captivity that is made palatable by its beauty. Ultimately, Spenser presents a distinctive account of human association that heightens the role of restraint in the formation of human bonds.

Texte intégralRésumé :
In this chapter Mapes elaborates on the rhetorical strategies of historicity, simplicity, lowbrow appreciation, pioneer spirit, and locality/sustainability. She turns to a data set of 90 corresponding Instagram (@nytfood) posts, documenting the multimodal tactics by which food media writers and users perform a kind of acceptable or “palatable” eliteness. One such tactic is the framing of “rough” and “refined,” and the juxtaposition of various forms of supposedly low and highbrow cultural artifacts or practices. These tactics, in turn, help establish two interdependent strategies or rhetorics for manufacturing status in capitalist society: fetishism and condescension. She argues that these two processes support the production and maintenance of elite authenticity and class privilege.

Texte intégralRésumé :
Cleft Palate is a craniofacial syndrome in which the two plates that form the hard palate are not completely joined. As a result, the soft tissue anatomy of the Eustachian Tube (ET) is altered. The ET is a collapsible tube which connects the middle ear (ME) with the nasopharynx (NP). The ET must be periodically opened to equalize ME and NP pressures and drain ME fluids. In healthy adults, ET openings occur during swallowing, where muscle contraction deforms the surrounding soft tissue. However, changes in tissue anatomy may lead to ET dysfunction (i.e. closure during swallowing) and the development of ME disorders such as Otitis Media (OM)[1]. These disorders are especially problematic in infants with cleft palate as they hinder speech, hearing and psychosocial development. Although surgical procedures can be used to repair a cleft palate, these procedures do not typically account the possible development of ET dysfunction and/or OM.

Dans ASME 2013 International Mechanical Engineering Congress and Exposition. American Society of Mechanical Engineers, 2013. http://dx.doi.org/10.1115/imece2013-62904.
Texte intégralRésumé :
In this study we used computational fluid dynamics (CFD) to analyze the therapeutic effect of an oral device (mandibular advancement splint – MAS, that protrudes the lower jaw during sleep) as a treatment for Obstructive Sleep Apnea (OSA). Anatomically-accurate upper airway (UA) computational models were reconstructed from magnetic resonance images (MRI) of 7 patients with and without a MAS device fitted. CFD simulations of UA airflow were performed at the maximum flow rate during inspiration. The CFD results indicated the lowest pressure often occurs close to the soft palate and the base of the tongue. The airway pressure gradient was estimated as the best indicator for treatment response since the change in the pressure drop forms a linear correlation with the change in patients’ Apnea-Hypopnea Index (AHI). This correlation has the potential to be developed into a model for predicting the outcome of the MAS treatment. However the rigid wall assumption of CFD models is the major uncertainty. To overcome this uncertainty we set up a full fluid-structure interaction model for a typical responder case with a compliant UA wall. The results demonstrated the different UA flow field associated with using MAS alleviated the airway collapse, which was successfully predicted for the untreated patient. We thus show for the first time that FSI is more accurate than CFD with rigid walls for the study of OSA, and can predict treatment response. Comparison of the FSI and CFD results for the UA flow and pressure profiles showed variation between the models. The structural deflection in oropharynx effectively reformed the flow pattern, however, the maximum pressure drops of both results were close. This supports the competence of the CFD method in clinical applications, where maximum pressure drop data can be used to develop a treatment-predicting model.

Texte intégralRésumé :
Due to the excessive demand to desalinate seawater to satisfy the domestic need in Qatar, it was needed to develop safe and cost effective desalination processes with the consideration of stringent regulation for water quality production and wastewater/brine discharge quality. The direct disposal of brines to the environment raised potential negative impact to the aquatic system and therefore the best practice is to minimize the volume of brine production and reuse it for beneficiary application. Several brine-dewatering techniques include both evaporative and non-evaporative approaches, which are capable to dewater high salinity brines with 50-350 g/L of total dissolved solids (TDS). The commonly adopted technology for dewatering brine is mechanical vapor compression that is known for its significant energy consumption up to 25 kWh/m3 of produced water for 50% of water recovery1. Non-evaporative membrane base technologies are a promising approach to dewater brines with minimum energy usage. Osmotically assisted reverse osmosis (OARO) is an advance membrane based technology for energy efficient and high recovery desalination of saline brine. OARO differ from reverse osmosis (RO) by adding saline sweep on permeate side to reduce osmotic pressure difference across the membrane to generate more water flux. The ongoing research work are based on mathematical/numerical approach that focuses on finding the optimum OARO configuration, inlet hydraulic pressure to avoid membrane burst and cost analysis. However, most of these studies are conducted by considering ideal conditions. In this study, an algorithm for simulating OARO process based on MATLAB and Aspen Plus to model membrane calculation and to design process configuration is considered to the effect of concentration polarization (CP) and reverse solute flux (RSF). The objective is to study the effect of inlet feed concentration and flowrate, sweep concentration and flowrate, inlet hydraulic pressure, number of stages, membrane size and characteristics and module configuration flow. In addition, technical economic analysis to evaluate the economic feasibility of OARO process. The stopping criteria of this model is the quality of water permeating at the feasible operating conditions and the cost. This model demonstrated high potential simulating OARO process to be used as a palate form for the user to predict the behavior of the process by varying operating conditions to desired outcomes.

Texte intégralRésumé :
The meaningful United States regulation of onshore oil and gas field waste/soil commenced in the mid 1980’s in response to a series of state, federal, industry and international initiatives. Most initiatives centered on the design, construction and operation of earthen pits used in the exploration and production of oil and gas (E&P). Prior to this time, earthen pits were constructed as needed by the operator and used in all phases of E&P activity. Chief concerns of the regulators were focused on what had gone into pits historically, what was going into them currently and was the E&P exemption excluding high volume E&P wastes from the Resource Conservation and Recovery Act (RCRA) regulations justified. Several investigations, including the comprehensive field study by the Environmental Protection Agency in 1987, determined E&P wastes are ostensibly non-hazardous. EPA concluded regulation of E&P wastes under RCRA Subtitle C was not necessary. To this day there is no U. S. federal regulatory program with exclusive jurisdiction over exempt E&P wastes. Other studies, primarily industry and academic, focusing on land limiting constituents, management practices and pit closure strategies revealed sodium salts and petroleum hydrocarbon in the form of diesel range organics were the primary limiting constituents. One state, Louisiana, adopted the technical aspects of these studies and developed a comprehensive regulation known as Statewide Order 29-B, which was based on the concept of limiting constituents and defined post closure performance standards. These standards limited salinity, sodicity, total metals and total petroleum hydrocarbon (oil & grease) with values varying with respect to landform, land use and closure technique. Other states have adopted some of the concepts and criteria advanced under 29-B but none are as comprehensive. Obviously there is a need to control what goes into pits and how pits should be closed. The industry would best be served by adopting the concepts and standards set forth in the Louisiana 29-B regulation. A few of the provisions could be changed to make it more palatable to industry without sacrificing the protection afforded human and animal health, safety and the environment. Internationally, particularly countries in South America embraced USEPA protocol for testing characteristically hazardous wastes, but 1) without the framework to handle the relatively large volume of non-hazardous E&P waste generated and 2) no regulations or protocols for on-site waste management. Several operators, although partners with state owned oil companies, on their own volition, applied the concepts and standards under Louisiana’s 29-B to rainforests in South America and rice paddies in Indonesia. Canada and European oil and gas producing countries have developed stringent standards not based on science, which favor costly treatment technologies. Generally, these countries prohibit cost effective on-site waste management and closure techniques. This paper traces the evolution of waste/soil remediation within the United States and internationally. We trace the progress as a function of time; the impetus for regulation; and probable future controls.
