Tuning band structures of photonic multilayers with positive and negative refractive index materials according to generalized Fibonacci and Thue-Morse sequences.

We investigate the photonic band structure, using the transfer-matrix method, in one-dimensional structures composed of a dispersive metamaterial A juxtaposed with a non-dispersive dielectric B according to the generalized Fibonacci and Thue-Morse sequences, which are ruled and characterized by two positive integer numbers, p  and q. We present the band structures of different generations of these sequences for both TE and TM modes and discuss how they are affected by the p  and q parameters and the ratio between the thicknesses of the building blocks. We obtain a new and very important analytical expression for the frequency in which the average refraction index vanishes, i.

Analysis of the effects of low-level laser therapy on muscle fatigue of the biceps brachii muscle of healthy individuals and spastic individuals: Study protocol for a single-center, randomized, double-blind, and controlled clinical trial.

Background: Muscular fatigue is caused by biochemical alterations that modify the mechanics of muscle contraction, resulting in negative changes in the performance of the contraction. Several resources are studied to mitigate this situation among which we can cite low-level laser therapy (LLLT). The effects of LLLT are being studied in healthy subjects with fibromyalgia and who are athletes, and currently the studies are being performed in spastic muscles with poststroke individuals.

Layperson's preference of the transverse occlusal plane in asymmetric facial model.

Objective: Facial asymmetries are common, especially deviated nose and chin. The clinician must consider these variables when establishing the smile, placement and angulation of the occlusal plane. The purpose of this article is to determine if nose and chin deviations affect the perception of laypeople towards different angulations of the occlusal plane cant.

Layperson's Esthetic Preference to the Presence or Absence of the Interdental Papillae in the Low Smile Line: A Web-based Study.

Purpose: To determine the layperson's esthetic preference to the visual display (presence) or lack thereof (absence) of the interdental papillae during minimum smiling or the low smile line patient type.

Materials And Methods: Two hundred lay-people were shown three-paired smile images indicative of a low gingival smile line patient type in which the vermillion border of the maxillary lip covered the mid-facial gingiva of the anterior teeth. The three images differed only with respect to [1] presence of interdental papillae, [2] absence of the interdental papilla ("black triangle"), or [3] absence of the interdental papillae (replaced with a long restorative contact area).

Application of microbial fuel cell technology for vinasse treatment and bioelectricity generation.

Objective: Our study evaluated the performance of different two-chambered microbial fuel cell (MFC) prototypes, operated with variable distance between electrodes and Nafion membrane and specific inoculum concentration, applied for vinasse treatment.

Results: The performance of the developed MFC resulted in a maximum current density of 1200 mA m and power density of 800 mW m in a period of 61 days. MFC performed a chemical oxygen demand removal at a rate ranging from 51 to 60%.

The facial flow concept: An organic orofacial analysis-the vertical component.

Orofacial analysis has been used by dentists for many years. The process involves applying mathematical rules, geometric principles, and straight lines to create either parallel or perpendicular references based on the true horizon and/or natural head position. These reference lines guide treatment planning and smile design for restorative treatments to achieve harmony between the new smile and the face.

Layperson's perception of axial midline angulation in asymmetric faces.

Objective: Asymmetric facial features such as a deviated nose and chin are common and known to affect smile esthetics. When presented with these asymmetries, the clinician must consider the impact they will have on the smile design parameters-especially the placement and angulation of the dental midline, which is a common starting point for a case involving smile design. The purpose of this article is to determine if the nose and chin deviations affect the perception of dental midline angulation.

Layperson's preference regarding orientation of the transverse occlusal plane and commissure line from the frontal perspective.

Statement Of Problem: Facial asymmetries in features such as lip commissure and interpupillary plane canting have been described as common conditions affecting smile esthetics. When presented with these asymmetries, the clinician must choose the reference line with which to orient the transverse occlusal plane of the planned dental restorations.

Purpose: The purpose of the online survey described in this study was to determine lay preferences regarding the transverse occlusal plane orientation in faces that display a cant of the commissure line viewed from the frontal perspective.

Perception of maxillary dental midline shift in asymmetric faces.

Purpose: The purpose of this article is to determine whether certain facial asymmetries (nose and chin) have an impact on the perception of the maxillary dental midline shift.

Materials And Methods: From a digitally created symmetric facial model (SFM) constructed in a previous study, a new asymmetric facial model (AFM) was created, with nose and chin deviated to the same side. Modifications were made on the AFM for shifts in the maxillary dental midline in both directions, resulting in a total of eight different images.

Compartment syndrome after total knee arthroplasty: regarding a clinical case.

Although compartment syndrome is a rare complication of total knee arthroplasty, it is one of the most devastating complications. It is defined as a situation of increased pressure within a closed osteofascial space that impairs the circulation and the functioning of the tissues inside this space, thereby leading to ischemia and tissue dysfunction. Here, a clinical case of a patient who was followed up in orthopedic outpatient consultations due to right gonarthrosis is presented.

Effect of a short-term exercise program on glycemic control measured by fructosamine test in type 2 diabetes patients.

Background: Glycated hemoglobin (A1C) and Fasting Plasma Glucose (FPG) are the two monitoring blood glucose tests most frequently used. However, both methods are shown to be insensitive to detect glycemic variations in short duration periods. Therefore, we aimed to assess the effect of a short-term exercise program on glycemic levels measured by fructosamine concentrations in type 2 diabetes patients.

Laypersons' perception of facial and dental asymmetries.

The purpose of this article was to determine the individual visual perception thresholds of certain facial and dental discrepancies for a symmetric face model (SFM). A facial photograph of a female subject's smile was digitally manipulated into an artificially symmetric picture. Modifications were made on the SFM for shifts in the dental midline, nose, and chin (group 1) and cants of dental midline and incisal plane (group 2), resulting in a total of 24 different images divided into two groups.
