Willets Point Land Use Study

The purpose of the study is to survey and map land use patterns and businesses in the Willets Point area of Queens, New York. Willets Point has been the subject of numerous recent proposals for redevelopment. The City's Economic Development Corporation released Requests for Expressions of Interest in November 2004 and recently qualified a small group of developers to present proposals for redevelopment of the area. The information and maps provided by this study will hopefully serve as background for discussions about the area. It was not within the scope of this study to evaluate existing proposals or develop alternative proposals. However, we have offered some preliminary assessments of current conditions and ideas that could serve as a foundation for more in-depth study of future opportunities

Surgical treatment of retrosternal extraosseous Ewing Sarcoma in a 6-years old female: a clamshell approach with hemysternectomy and application of a non-crosslinked extracellular matrix

Background Ewing Sarcoma (ES) and Neuroblastoma (NB) belong to a family of tumours of primitive neuroectodermal origin (PNET) that occurs in both bone and soft tissue. Notwithstanding ES and NB are two distinct malignant tumours, sometimes there could be a link between them. Case report We describe a case of an extraosseous ES localized in the retrosternal region and the upper lobe of the right lung, which had been previously treated for NB in a 6 years old female. We treated this case with a clamshell approach which allows, in a one-step surgery, a complete excision of the mass reconstructing the hemysternectomy with a non-crosslinked matrix. Conclusion the clamshell approach is therefore useful to achieve the retrosternal space and the lung with a single surgical access. According to our experience, we consider appropriate to use a non-crosslinked matrix for sternal reconstruction

Modelos pedagógicos de ensino superior a distância

No Brasil, vislumbra-se que uns dos desafios postos aos Modelos Pedagógicos de Educação a Distância no ensino superior, é transcender do discurso de Modelos com potencialidades voltadas à interação e à colaboração pedagógica virtuais para a prática cotidiana de quem a consolida. Essa configuração que caracteriza a EaD online tem sido indicada com potenciais para alterar as formas de Educação. Nesta pesquisa, objetivou-se analisar como as Tecnologias de Informações e Comunicação digitais (re)configuram Modelos Pedagógicos de EaD tradicionais para online no ensino superior. Trata-se de uma pesquisa de natureza qualitativa, constituída por uma revisão bibliográfica e um estudo de caso coletivo, do qual participaram 3 instituições brasileiras: Universidade Federal do Rio Grande do Norte, Universidade Federal de Santa Catarina e Universidade Federal Fluminense, e 2 cursos: Licenciatura em Física e Licenciatura em Matemática. Utilizaram-se, como instrumentos de coleta de dados entrevistas orais estruturadas, organizadas em um guia composto por questões abertas aplicadas a 29 docentes, dados dos projetos dos cursos dessas instituições, do Sistema Universidade Aberta do Brasil e de documentos legislativos. Os resultados encontram-se organizados nas seguintes categorias de análise: mudanças paradigmáticas; componente presencial; recursos didáticos; interação pedagógica; e aprendizagem colaborativa. Constata-se que, nas instituições participantes desta pesquisa, não há uma abordagem única para o uso das Tecnologia de Informação e Comunicação na Educação a Distância e que existem vários Modelos híbridos (online e offline) ou puros (online). Os resultados igualmente apontam que o desenvolvimento com fluência e crítica tecnológica dos docentes, e também dos alunos, e o acesso garantido às tecnologias que possibilitam conexão de qualidade constituem um dos desafios para a (re)configuração do Modelo de Educação a Distância tradicional para o online. Entretanto, a partir do discurso dos docentes, pode-se aferir que o Modelo de Educação a Distância brasileiro está cada vez mais sendo potencializado pelo Modelo online.In Brazil, it is envisaged that some of the challenges tackled for the Pedagogical Models of Distance Education in higher education is to transcend the discourse Models with the competences turned to the interaction and collaboration of the virtual pedagogical model in the daily practice of the person who consolidates. This background featuring online DE has been indicated as potential method to change the ways of education. This research aims to investigate how the digital Information and Communication Technologies (re)arrange traditional Pedagogical Models of Distance Education to the online model for the higher education. This is a qualitative research, containing information based on a literature review and a shared case study, which were conducted by three institutions in Brazil – Federal University of Rio Grande do Norte, Federal University of Santa Catarina and Federal University Fluminense – and two under graduation courses, in Physics and Mathematics. The resources used for collecting the data were: oral interviews, organized in a guide consisting in open questions applied at 29 professors, and some assignment data of the courses offered by the System Open University of Brazil and legislative documents. The results are organized in the following categories of analysis: paradigmatic changes; classroom component; didactic resources; pedagogical interaction, and collaborative learning. It seems that, for the Institution of higher education participating in this study, there is not a single method to the use of Information and Communication Technologies in distance education and there are several hybrid models (online and offline) or only (online). The results correspondingly indicates that exist an eloquence and critic on the development of technological from the professor, as well as from the students, and the guarantee access to the technologies which enable a good quality connection is one of the challenges at the (re) configuration on the traditional model of online distance education. However, from the discourse of teachers, we might infer that the brasilian model will be increasingly enhanced by Model online.Universidade Aberta; Pavilhão do Conhecimento; LEA

Precisione nella determinazione della lunghezza di lavoro mediante localizzatori elettronici d’apice, radiologia digitale e prova visiva: presentazione di una nuova metodica sperimentale di indagine – uno studio ex-vivo. Exact determination of the working length by electronic apex locators, digital radiology, and visual test: presentation of a new experimental research strategy – an ex-vivo study.

Abstract Objectives: This study compared: 1) the accuracy of three different electronic apex locators (EALs) in detecting the apical foramen ex-vivo under clinical conditions; 2) the accuracy of digital radiography and EALs in determining the K-file position in the root canal; 3) the accuracy of two different radiographic planes; (4) the precision of #10, #15, and #20 K-files in electronic measurements; 5) the precision of EALs in relation to the dental anatomy classification (anterior, bicuspids, and molars). Materials and methods: The length of 101 extracted human teeth was measured with three different EALs (Endex, Propex II and Root ZX), with RVG and compared to the actual length. Experimental procedures were performed using an endodontic training kit (Pro-Train). Results: The statistical analysis showed that Endex and Propex II were more accurate than Root ZX in determining the working length (WL). The t-test showed no statistically significant difference of accuracy between the two radiographic planes examined. The t-test showed no significant difference between the three different K-file size measurements. EALs and RVG are less accurate in anterior teeth. Conclusions: To prevent overestimation of the root canal length using the EALs tested, 1 mm should be subtracted from the measurement on the ‘‘APEX’’ mark. Instrument sizes did not affect the accuracy of EALs. EALs showed to be more accurate in determining the WL than RVG. 2011 Societa` Italiana di Endodonzia. Published by Elsevier Srl.

Chromosome 18q-Syndrome and 1p terminal duplication in a patient with bilateral vesicoureteral reflux: case report and literature revision

Background: Vesico-ureteral reflux (VUR) is a dynamic event in which a retrograde flow of urine is present into the upper tracts. VUR may occur isolated or in association with other congenital abnormalities or as part of syndromic entities. We present a patient with a bilateral primary VUR, syndromic disease caused by a large deletion of 18q (18q21.3-qter) and terminal duplication of 1p (1p36.32-p36.33). Case report: The patient was 8 years old female with a disease including moderate growth retardation, psychomotor retardation, facial dysmorphism, single umbilical artery, umbilical hernia, urachal remnant, bilateral congenital clubfeet and renal-urinary disease. Chromosomal analysis and Array-CGH revealed two heterozygous chromosomal rearrangements: 1p terminal duplication and de novo 18q terminal deletion. She referred to our clinic to evaluation of bilateral hydronephrosis and right renal cortex thinning. Voiding cystourethrography demonstrated bilateral grade IV VUR and dimercaptosuccinic acid renal scintigraphy confirmed right renal cortex thinning and showed a cortical uptake of 75% of the left kidney and 25% of the right kidney. The patient underwent ureterovesical reimplantation after failure of 3 endoscopic submeatal Deflux injections with VUR resolution. Conclusions: This is the first report involving a patient with 18q-syndrome and contemporary presence of 1p chromosomal terminal duplication. The coexistence of two chromosomal rearrangements complicates the clinical picture and creates a chimeric disorder (marked by characteristics of both chromosomal anomalies). Kidney problems, primarily VUR is reported in 15% of patients affected by 18-q syndrome and no cases is reported in the literature regarding a correlation between VUR and 1p36 chromosomal duplication

IS CATEGORY MANAGEMENT IN SMALL SUPERMARKETS WORTH THE EFFORT?

Category management (CM) is an important tool to strengthen the relationship between manufacturers and retailers. This process has been associated with large corporate retailers; however, some recent researches show that CM is open to companies of any type or size. This possibility is important in emerging markets, where neighborhood supermarkets are still representative and are often considered an alternative for manufacturers to achieve higher margins compared to big chains. In this context, the aim of this research was to analyze the results of a CM initiative in small neighborhood supermarkets from a manufacturer perspective. Data for the study comes from a food manufacturer in Brazil that implemented a CM process with 180 small retailers. A quantitative analysis was conducted in order to analyze the effect of the program on the food manufacturer’s sales and market share. Our analysis suggests an overall positive effect of the program on both, sales and market shar

LIMB BODY WALL COMPLEX IN TWO HETEROZYGOTIC TWINS: A CASE REPORT

Introdution. Limb-Body Wall Complex (LBWC) is a congenital defect which includes at least two of the following characteristics: abdominal and/or thoracic body wall defects, exencephaly or encephalocoele with or without craniofacial defects (56%) and spinal defects associated with marked vertebral or sacral defects (95%). Case Report. We present a case report of an infant with LBWC, borned by diamniotic twin pregnancy. A prenatal ultrasound reported an healthy fetus and a fetus with multiple malformations. At birth we found a big abdominal wall defect, absence of scrotal sac and testicles, asymmetric chest and no major deformities in craniofacial region. At 2 hours of life, we removed the amniotic sac, we put the stomach and the spleen in the abdominal cavity, which is virtual, and positioned a spring-loaded silo. At 15th day of life we had complete reduction of the intestinal loops and liver and we closed the wall defect with a prosthesis and a cryopreserved skin. The general conditions of the patient, very severe since birth, became progressively worse and he died in the 21st day of life. Discussion. Once the diagnosis is done the physician should offer the parents a therapeutic abortion, and above all, in case they want to carry the pregnancy to term, we need to prepare them to the severity of the malformation and the high probability of death

Durability of adhesion between an adhesive and post-space dentin: Push-out evaluation at one and six months.

Aims The aim of this study was to investigate, by means of the push-out test, the bond of Prime & Bond NT at various post-space dentin locations and the influence of time of water storage on bond strength values. Methods 30 single-rooted teeth were used for the bond strength measurement. In each tooth fiber posts were cemented with the commercial bonding system “Prime & Bond NT” in combination with the resin-based filling material “Opticore Cure Core Composite”. After 24 h (group A: 10 roots), 1 month (group B: 10 roots), and 6 months (group C: 10 roots) of water storage, the specimens were sectioned in 1 mm-thick slices for the push-out test. The data were divided into three regions (coronal/middle/apical) and analyzed using Kruskal-Wallis Test and Mann-Whitney U Test (p<0.05). Results The bond strength values registered did not show statistically significant differences within group A and C; within group B statistically significant differences were found between the coronal and the middle thirds and between the coronal and the apical third. The apical bond strength values did not show any statistically significant difference among the three groups (Kruskal-Wallis test); in the middle thirds a statistically significant difference was found at 6 months when compared with the 24 h and 1-month samples. In the coronal thirds was found a statistically significant difference between 1 month and 6 months. Analysis of the specimens under optical microscope revealed a prevalence of adhesive failures between fiber post and root dentin. Conclusions Bond strength values are lower at the apical third. Over time the adhesion of the fiberpost/luting cement/post-space dentin does not remain stable

Esophagogastric dissociation reduces the re-operation rate for persistent gastroesophageal reflux in severely neurologically impaired children

Purpose: In this study we want to demonstrate the effectiveness of the esophagogastric dissociation as a first level operation in treatment of the gastroesophageal reflux in severe neurologically impaired children, in term of a reduction of reoperation rate.Methods: We divided patients operated from 1998 to 2005 in a group A, composed by children treated with fundoplication, and in a group AR, composed by the patients of group A who had a recurrence of reflux and that was treated with esophagogastric dissociation. Patients operated from 2005 to 2013 were selected on the basis of the severity of the neurological impairment and were divided in a group B, treated with fundoplication, and in a group C of more severe impaired children, treated with esophagogastric dissociation. Data regarding the complications of the A and C groups were analyzed with Fisher’s test.Results: We evaluated 63 patients: 34 (54 %) in group A, 11 in group AR, 15 (23.6 %) in group B, 14 (22.4 %) in group C. The Fisher’s test showed a non significant difference with a p value of 0.2.Conclusion: Despite of statistic result we believe that TOGD is a useful procedure as the first choice of surgical management in severe neurological impaired children affected by gastroesophageal reflux

Split-appendix technique: Alternative urinary diversion for pediatric complete incontinence

We report our series of selected patients with complete incontinence in whom the appendix was divided and utilized for creating two continent catheterizable stomas. All patients were treated for urinary and fecal incontinence by split appendix technique. The appendix was divided into two different parts preserving adequate perfusion and used for creating an appendicocecostomy (ACE) and an appendicovesicostomy at the same time. After a clinical and radiological follow up, our patients referred a good acceptance and an easily management of the stomas in order to stay dry for all day from urine and feces with improving of their quality of life. The combination of ACE and Mitrofanoff principle have revolutionized the management of urinary and fecal incontinence in patients who are unable to utilize their urethra to keep themselves dry
