1. Challenges in Management of Tracheobronchial Foreign Bodies with Delayed Presentation: An Institutional Experience
Abstract Introduction Airway foreign bodies are emergencies involving multidisciplinary departments like Pediatrics, Aneasthesiology and Otorhinolaryngology. It is always a challenge to diagnose and manage patients who present late to our emergencies. Objective In the present study, we aim to analyze the various challenges faced during the management of tr

2. Is There a Precise Correlation between the Lengths of the Peritoneal Reflection and the Middle Rectal Valve?
ABSTRACT Introduction Pelvic anatomy remains a challenge, and thorough knowledge of its intricate landmarks has major clinical and surgical implications in several medical specialties. The peritoneal reflection is an important landmark in intraluminal surgery, rectal trauma, impalement, and rectal adenocarcinoma. Objectives To investigate the correlation b

3. PARAMETERS FOR MODELING PASSIVE SUSPENSIONS OF SPRAY BARS
ABSTRACT The uniformity and quality of spraying depend on the stability of the spray boom, defined as the suspension system between the boom and the machine chassis. This paper presents a procedure for improving the performance of passive spray bar suspensions through parameter adjustment. Two multibody dynamics models of a tractor sprayer set were developed

4. A Five-Year Review on Pediatric Foreign Body Aspiration
Abstract Introduction Foreign body aspiration is a leading cause of accidental death in children. Clinical presentation varies from non-specific respiratory symptoms to respiratory failure making diagnosis challenging. Objective To review pediatric patients who underwent bronchoscopy due to suspicion of foreign body aspiration at a tertiary center in Malay

5. PMMA-SiO2 Organic-Inorganic Hybrid Coating Application to Ti-6Al-4V Alloy Prepared through the Sol-Gel Method
Siloxane-poly(methyl methacrylate) (PMMA) hybrid was synthesized based on the sol-gel method and applied to Ti-6Al-4V through dip-coating. The structural feature of the hybrid was subjected to Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TG); its morphological properties were analyzed through scanning electron microscope (SE

6. Prevalence and intensity of pain during diagnostic hysteroscopy in women attending an infertility clinic: analysis of 489 cases
RESUMO Objetivo Investigar a prevalência e a intensidade da percepção da dor durante a histeroscopia diagnóstica, bem como os possíveis fatores relacionados. Métodos Foram incluídas 489 mulheres submetidas à propedêutica de infertilidade. A histeroscopia diagnóstica foi realizada sem analgesia ou anestesia, por ginecologistas com níveis de exper

7. MANIFESTAÇÕES DA HISTERIA NA CONTEMPORANEIDADE
RESUMO: Este artigo aborda as manifestações da histeria na contemporaneidade, retomando os conceitos de corpo e sintoma como construções subjetivas do sujeito psíquico, nos constructos de Freud e Lacan. Do corpo, nas neuroses clássicas, ao corpo nas neuroses hoje, surge a questão da diferença na apresentação dos sintomas neuróticos. Propomos o con

8. Interaction dam-reservoir: study of conservative and dissipative effects
Resumo Neste trabalho, a equação de Laplace é resolvida analiticamente no plano complexo para o campo de pressões hidrodinâmicas gerado pelo movimento de corpo rígido da barragem na presença de um meio fluido infinito e incompressível (um reservatório). A força exercida pelo fluido do reservatório na face da estrutura da barragem é então determi

9. Design and Analysis of Flexible Hinge Used for Unfolding Spacecraft Solar Panels
ABSTRACT: Two stiffness models for a flexible hinge with large rotation angle are established based on the pseudo-rigid body method and the series or parallel relationship of flexible units. Finite element simulation of the flexible hinge is conducted in ANSYS to verify the two stiffness models of the flexible hinge. A multi-objective optimization method is

10. Fish Bone Foreign Body: The Role of Imaging
Abstract Introduction Fish bone foreign body (FFB) impaction in the upper aerodigestive tract is a common cause for emergency department referral. Its management varies in both diagnosis and treatment paradigms. Fish bone foreign bodies are more commonly found in the oropharynx in cases of patients < 40 years old, and in the esophagus in cases of patients

11. Three-Dimensional Determination of Superposed Helical Wires Constraint Ability
Abstract A three-dimensional theoretical model for predicting the maximum force sustained by a flexible line wound around a rigid cylindrical body is developed based on Clebsch-Kirchhoff equilibrium equations, considering its bending rigidity, no sliding, modified non-linear frictional law in terms of stress and an external pressure exerted on the line.

12. Modelling of Rocking and Sliding Effects in the Seismic Analysis of a Free-Standing Column
Abstract A study on the seismic response of a free-standing marble column, including rocking and sliding effects, is presented in this paper. The rocking-sliding model implemented for the development of the analyses corresponds to the basic theoretical and numerical simulation of the dynamic phenomenon. The assessment procedure adopted for the application of
