Radicular Cyst with Squamous Odontogenic Tumor-like Proliferation: An Unusual Entity

Squamous odontogenic tumor-like proliferation (SOT-LP) is a nonneoplastic lesion with a histological pattern similar to that of the SOT. This entity is characterized by SOT proliferations isolated in the cyst wall of an odontogenic cyst. This pattern is rarely seen in radicular cysts. The nature of these proliferations is not clear, and there is a varied opinion on the origin. Although it has a benign behavior, it should be differentiated from other aggressive lesions such as intraosseous carcinoma, ameloblastoma, odontogenic keratocyst, and SOT. Knowledge about this unusual lesion can help in the accurate diagnosis and treatment of the patients. Here, we are discussing a rare case of an SOT-LP emerging in a radicular cyst of the maxilla.
Effect of pressure and infill density parameter setting on morphological and mechanical properties of polycaprolactone printed scaffold using desktop 3D bioprinter

Three dimensional (3D) bioprinting is the process of building a 3D construct containing biological cells. There are varies set of printing parameter involved in 3D bioprinting system that will affect the structure and the mechanical properties of the bioprinted construct. This study was done to investigated the effect of extrusion pressure and infill density on the polycaprolactone (PCL) 3D printed construct’s morphology, printing accuracy and compressive strength. Based on morphological evaluations using scanning electron microscope, the printed scaffold was suggested to be at the best condition at pressure 60psi using 80% infill setting. Besides, the mechanical testing revealed the printed scaffold was successfully fabricated without losing its mechanical integrity. This is a good indication for PCL as structural host material to obtain functionalized 3D scaffold using bioprinting method.
How does technological parameters impact the static current gain of InP-based Single Heterojunction Bipolar Transistor?

In telecommunication systems, Heterojunction Bipolar Transistors (HBTs) are used extensively due to their good electrical characteristics. The work presented in this paper aims to enhance the electrical performance of the InP / InGaAs Single Heterojunction Bipolar Transistor (SHBT) in terms of the static current gain β. Silvaco’s TCAD tools were used for the simulation of the output characteristics of the studied electronic device. Initially, we used the interactive tool Deckbuild to define the simulation program and the device editor DevEdit to design the device structure, and we also used the simulator Atlas which allows the prediction of the electrical characteristics of most semiconductor devices. Because of several phenomena occuring within the electronic device SHBT, we added some physical models included in the simulator such as SRH, BBT.STD. Afterwards, we investigated the influence of doping concentrations of the base and the collector Nb and Nc on the electrical performance of the InP/InGaAs SHBT, and particularly in terms of the static current gain β. Finally, based on optimal values of the selected parameters, we have defined an optimized device that has a highest current gain β.
Postoperative Changes of the Frontal Facial Soft Tissues in Patients with Mandibular Prognathism and Mandibular Deviation

This study was designed to evaluate the morphological changes of the frontal facial soft tissue in prognathic patients with mandibular deviation who had undergone One-jaw or Two-jaw surgery. The subjects were divided into two groups: Group 1 (Two-jaw group) consisted of 18 skeletal Class M female patients who had undergone Le Fort I osteotomy and Sagittal Splitting Ramus Osteotomy (SSRO). Group 2 (One-jaw group) comprised 18 skeletal Class HI female patients treated by only SSRO.A pair of pre-and post-operative standardized frontal facial photos were used for soft tissue analysis.The angular and linear measurements of the nose, lip, and lower facial lines were studied on the standardized frontal facial photos.The results obtained were as follows:1. The quantity of postoperative Me deviation significantly decreased in the Two-jaw surgery group.2. No change in the nose width was observed in the One-jaw surgery group, while the nose width was significantly increased after surgery in the Two-jaw surgery group. Asymmetric nose width before surgery changed to the symmetric one after surgery in the Two-jaw surgery group.3. Lip width was significantly increased in the Twojaw group after surgery. The difference in the lip width between deviated and non-deviation sides was decreased in both groups after surgery. Asymmetric lip width before surgery improved in both groups after surgery.4. The lip line and the lower facial line improved to a more suitable inclination after surgery in both groups.
Exploring self-reported and observed feeding practices of Rhode Island Head Start teachers

Background: Head Start (HS) teachers care for low-income and ethnically diverse preschool-aged children who are disproportionately impacted by obesity. While it is known that parent feeding practices influence child weight status and eating behaviors, little is known about HS teacher feeding practices. The limited number of studies with HS teachers have been completed primarily with self-report measures, which have documented limitations such as response bias. Capturing HS teacher feeding practices through self-report and observations may provide valuable information needed to evaluate the inconsistencies of current findings. Methods: Rhode Island HS teachers (n=85) were observed and feeding behaviors coded using the Mealtime Behavior Observation Scale, adapted from the Environmental Policy Assessment and Observation (EPAO) tool. Postobservation, teachers completed the Children’s Eating Scale, adapted from the EPAO Self-Report (EPAO-SR), to capture self-reported feeding practices. Correlations (Spearman) were used to explore associations between self-reported and observed items (14) that were intended to measure the same feeding practice. Chi-square tests were also used to compare the level of consistency between measures and socio-educational factors. Results: Teachers were predominantly non-Hispanic White (89%) and female (98%). Not all self-reported and observed feeding practices were related. After aligning feeding practices on the self-report and observation scales, self-reported and observed “use of food as a reward” was the only significantly related feeding practice (r=22, p=.04). No significant associations were found with teachers’ self-reported years of experience, nutrition training, or desired weight status. Conclusions: Even though items on the self-report and observation measures were designed to capture identical feeding practices, most of them were not significantly related. It is possible that because HS has such a clear policy with regards to the “use of food as a reward”, this practice was significantly related. Currently self-report measures are used to capture feeding practices, yet inconsistencies between measures of self-report and observation exist. Further understanding of these inconsistencies is needed to better capture teacher feeding practices.
Computer-Assisted Orthopaedic Surgery: A New Paradigm

Summary Orthopaedic surgery has benefited from significant progress in surgical techniques and implants through advances in technology and science. Recent developments integrating medical imaging and spatial tracking technologies open an entirely new field. A virtual reality image allows the surgeon to plan and simulate the entire procedure before the actual case; follow in real-time the position of surgical tools, implants, and bone in different planes simultaneously; and obtain a precise digital record of the operation performed. These enhancing systems promise to empower the surgeon as the accuracy and safety in the operating room can dramatically be improved. A myriad of applications is currently under development, embracing every orthopaedic surgery subspecialty. Sound clinical trials, cost, availability, and practicality are the challenges these new technologies face, but it is very likely that they will soon prove their benefits for the patient and surgeon.
Ballistic phonons and the transition to second sound in solid 3 He and 4 He

We have studied the propagation of ballistic phonons in solid 4 He and 3 He using the fast-heat-pulse technique. At sufficiently low temperatures (≤0.1 K), the intensities and velocities of the ballistic phonons are in good agreement with phonon focusing and ultrasonic data. The temperature dependence of the velocity and intensity of the slow transverse mode in 3 He (molar volume range 23.7-24.5 cm 3 /mole) shows anomalous behavior in the vicinity of 0.2 K as this mode borrows weight from the higher lying branches. The implications of these measurements for specific-heat data are discussed. In addition, the numerical value of the measured second-sound velocity (which is independent of orientation) for 3 He is shown to be in close agreement with that calculated using first-sound velocities determined by ultrasonics, but significantly different from v Debye /√3; the result in the isotropic case.

Myocardial Protective Effect of Histidine-Tryptophan-Ketoglutarate Solution and Cold Blood Cardioplegic Solution in Pediatric Cardiac Surgery

Background: There is limited data on comparisons between the effect of histidin-etryptophan-ketoglutarate (HTK) solution and cold blood cardioplegic (CBC) solution in pediatric cardiac surgery. The purpose of this study was to compare the myocardial protective effect of HTK solution and CBC solution in patients undergoing pediatric cardiac surgery. Materials and Methods: We selected 49 patients with ventricular septal defect and atrial septal defect. HTK solution was used in 21 patients and CBC solution was used in 28 patents. HTK solution was given as a single dose, whereas CBC solution was used in the usual multi-dose method. The incidence of EKG change and concentration of Troponin T and CK-MB were compared for the evaluation of myocardial damage. Results: There were no significant differences in the incidence of ST, T segment change by EKG and serial cardiac enzyme levels between two groups. Conclusion: These results suggested that the myocardial protective effect of HTK solution was similar to CBC solution in simple pediatric cardiac surgery.

Comparison between effects of ketamine and midazolam as co-induction agents with propofol for prosealTM laryngeal mask insertion

Introduction: Optimal conditions during supraglottic airway placement are important to prevent adverse events associated with inadequate depth of anaesthesia. This study compared propofol co-induction with ketamine or midazolam during ProSeal TM Laryngeal Mask Airway (PLMA) insertion. Materials and Methods: A total of 118 ASA I or II patients aged between 18 to 60 years requiring PLMA insertion for surgery were recruited into this prospective, randomised and double blind study. Patients were grouped into propofol (2mg/kg) co-induction with either ketamine (0.5mg/kg) or midazolam (0.03mg/kg). During PLMA insertion, the degree of mouth opening, ease of insertion, swallowing, coughing or gagging, movement and laryngospasm were scored and haemodynamic changes were recorded. Overall insertion conditions were further graded into excellent, good, poor or unacceptable. Results: The ketamine-propofol group had significantly better mouth opening ( p= 0.01) and shorter duration of apnoea ( p p Conclusion: Propofol co-induction with either ketamine or midazolam conferred comparable PLMA placement conditions.
Pneumatic Hyperelastic Actuators for Grasping Curved Organic Objects

Soft robotic grippers often incorporate pneumatically-driven actuators that can elastically deform to grasp delicate, curved organic objects with minimal surface damage. The complexity of the actuator geometry and the nonlinear stress–strain behavior of the stretchable material during inflation make it difficult to predict actuator performance prior to prototype fabrication. In this work, a scalable modular elastic air-driven actuator made from polydimethylsiloxane (PDMS) is developed for a mechanically compliant robotic gripper that grasps individual horticultural plants and fungi during automated harvesting. The key geometric design parameters include the expandable surface area and wall thickness of the deformable structure used to make contact with the target object. The impact of these parameters on actuator displacement is initially explored through simulation using the Mooney–Rivlin model of hyperelastic materials. In addition, several actuator prototypes with varying expandable wall thicknesses are fabricated using a multistep soft-lithography molding process and are inserted in a closed ring assembly for experimental testing. The gripper performance is evaluated in terms of contact force, contact area with the target, and maximum payload before slippage. The viability of the gripper with PDMS actuators for horticultural harvesting applications is illustrated by gently grasping a variety of mushroom caps.

MnxZn1-xFe2O4 coated with β-Bi2O3 and β-MnO2 as a highly efficient and magnetically recyclable photocatalyst for water treatment

ABSTRACT Magnetic photocatalyst β-Bi2O3/β-MnO2/MnxZn1-xFe2O4 (BM/MZF) was successfully synthesised using dip-calcination method. The structure and properties of as-prepared samples were characterised by XRD, SEM, FT-IR, UV-DRS and VSM. The peaks of β-Bi2O3 and β-MnO2 without an obvious change in the XRD pattern of BM/MZF confirmed that their morphology and phase stayed stable during the process of preparation. BM/MZF with a structure of bulked MnxZn1-xFe2O4 coated with spherical and flaky β-Bi2O3 and spherical β-MnO2 possesses good optional and magnetic abilities. The band gap of BM/MZF (2.34 eV) was less than that of β-Bi2O3 (2.48 eV) or β-Bi2O3/MnxZn1-xFe2O4 (2.43 eV). Under visible light irradiation, the photodegradation rate of RhB using BM/MZF was 98.9% in 1.75 h, which was higher than that using β-Bi2O3 (48%) or β-Bi2O3/MnxZn1-xFe2O4 (65%), and the photodegradation rate was still 95.7% after five cycles. The saturation magnetisation (Ms) of BM/MZF was 6.95 emu/g, and the average recovery rate was 87%.
Thermoresponsive polymers under high pressure

This thesis investigates the phase behavior in aqueous poly(N-isopropylacrylamide) (PNIPAM) solutions under pressure using neutron and light scattering techniques. The influence of pressure on the hydration state of PNIPAM and on the formation of the mesoglobules were studied in detail. Time-resolved investigations after rapid pressure jumps allowed the characterization of the growth kinetics of the mesoglobules. The effect of pressure on the co-nonsolvency behavior was investigated as well.
Microstructures and Hardness Prediction of an Ultrafine-Grained Al-2024 Alloy

High-pressure torsion (HPT) is a high efficiency processing method for fabricating bulk ultrafine-grained metallic materials. This work investigates microstructures and evaluates the corresponding strengthening components in the center of HPT disks, where effective shear strains are very low. An Al-4.63Cu-1.51Mg (wt. %) alloy was processed by HPT for 5 rotations. Non-equilibrium grain and sub-grain boundaries were observed using scanning transmission electron microscopy in the center area of HPT disks. Solute co-cluster segregation at grain boundaries was found by energy dispersive spectrometry. Quantitative analysis of X-ray diffraction patterns showed that the average microstrain, crystalline size, and dislocation density were (1.32 ± 0.07) × 10−3, 61.9 ± 1.4 nm, and (2.58 ± 0.07) × 1014 m−2, respectively. The ultra-high average hardness increment was predicted on multiple mechanisms due to ultra-high dislocation densities, grain refinement, and co-cluster–defect complexes.

Corrosion Fatigue of Aluminum-Copper-Lithium Alloy 2050-T84 Submitted at Salt Spray and Aqueous Saline Solution

Interest in the improvement of the structural performance of aircraft has begun in the substitution of aluminum alloys due to the possibility of reduction of density, an increase of stiffness, high fracture toughness, greater resistance to the propagation of cracks by fatigue and greater resistance to corrosion. In these issues, the aluminum-copper-lithium alloy 2050-T84 is outstanding, which presents excellent mechanical properties even when subjected to aggressive atmospheres. The failure of structural components of aircraft occurs due to several factors that may arise from microstructural defects and/or applied static or cyclic stresses associated with atypical environments such as cryogenic or corrosive. In this sense, the results have evidenced the presence of precipitates that influence in the increase of the mechanical strength, behavior of fracture toughness, fatigue life, and corrosion fatigue, in different temperatures and aggressive means. Tensile and fracture toughness tests at 23 and (cid:1) 60°C the material showed ductility retention without a significant difference in the results. Fatigue crack growth in air and corrosion fatigue with 3.5 and 5% NaCl and aqueous solution with 3.5% NaCl showed a meaning difference in the threshold region; however, for the Paris region at the saline environment, fatigue crack growth (FCG) rates are similar.
RELATIONSHIP BETWEEN THE SCIATIC NERVE AND PIRIFORMIS MUSCLE

The sciatic nerve begins in pelvis and normally leaves the pelvis by passing through the greater sciatic foramen below the piriformis muscle. Normally it terminates at the superior angle of the popliteal fossa by dividing into the tibial and common peroneal nerve. However, it may rarely be terminated within the pelvis. In such cases, the tibial nerve and the common peroneal nerve may leave the pelvis through different routes. These variations may cause nerve compressions under other anatomic structures, resulting in non-discogenic sciatica. The aim of present study was to define the relationship between the sciatic nerve and the piriformis muscle. 100 gluteal regions were examined in 50 properly embalmed adult male cadavers. In 96%of the cases, the exit of sciatic nerve from the pelvis was observed as a whole nerve without any division, whereas in 4% of the cases, the tibial branch of the sciatic nerve left the pelvis through the infra piriform foramen and common peroneal branch through the piriformis muscle. The differences in the exit routes of these two nerves are important in clarifying the clinical etiology of non discogenic sciatica. Keywords- Greater sciatic foramen, Piriformis syndrome, Sciatica, Anatomic variation,
Effects of Thermal Treatment on Electrical Conductivity and Hardness of Polyaniline-Silica Composites

Physical stability of conducting polymers is considerably important for their applications in electronics. Here, we studied the thermal annealing effects of conducting polyaniline (PANI) composites with a sol-gel silica on their mechanical and electrical properties. Films were prepared onto a substrate by simple drop-casting method using solutions including aniline, tetraethyl orthosilicate (TEOS), and ammonium persulfate. Spectroscopic analyses confirm the emeraldine-salt phase of PANI and the presence of silica network in the film. Nanoindentation measurement showed that, although the improvement was observed in the PANI/TEOS hybrid films, the annealing temperature was not a significant factor for the hardness. The electrical conductivity of the composite decreased from 5.5 to 1.9 S/cm after annealing, due to the slight dedoping of PANI by heat-induced removal of the HCl dopant.
Destructuring / restructuring model for quasi-static behavior of granular soils

In this paper, one of the main assumptions related to soil fabric and its evolution with the stress state, considered in an elasto-plastic constitutive model previously proposed by the authors, is re-visited based on additional assessment of literature results. The new evidence justifies the introduction of a target soil structure concept towards which the current soil fabric continuously progresses, while the target structure instantaneously evolves with the stress state. The relationship between the target structure and the current stress tensors can be described by a power law of which coefficient value is suggested by the literature data. RÉSUMÉ: Dans ce papier on discute une des principales hypothèses concernant la structure des sols et son évolution avec l’état de contrainte, présentée précédemment dans une loi élasto-plastique proposée par les auteurs. L’hypothèse est discutée sur la base des analyses de données présentées dans la littérature. Ces observations justifient l’introduction d’un concept de structure cible, vers lequel la structure actuelle évolue progressivement, alors que la structure cible évolue instantanément avec l’état de contrainte. La relation entre le tenseur de structure cible et le tenseur de contrainte peut être décrite par une loi de puissance dont la valeur de l’exposant est suggérée par des données de la littérature.
