Mucoepidermoid carcinoma is a malignant tumor that affects the salivary glands, particularly the parotid gland. Involvement of the accessory salivary glands is rarer; some cases have been described in the literature. The clinical symptoms are atypical with a slow and silent evolution which delays the diagnosis. The diagnosis is based on clinical, radiological and anatomopathological examination of diagnostic and prognostic interest. The management is essentially surgical with carcinological marg...

The productivity of coconut in Guerrero, Mexico has decreased substantially. The experts recommended a diagnosis of the soil fertility before launching a sound reforestation program. The introduction of Green Dwarf Coconut (GDC) due to its high productivity was suggested; however, nitrogen (N) was of higher interest since GDC is a highly demanding material. In this work, the contents, in parts per million (ppm), of nitrogen (N) as nitrate (N-NO₃) as well as its chemical variability (C...

Orofacial manifestations occur frequently in rheumatic diseases and usually represent early signs of disease or of its activity that are still neglected in clinical practice. Among the autoimmune rheumatic diseases with potential for oral manifestations, rheumatoid arthritis (RA), inflammatory myopathies (IM), systemic sclerosis (SSc), systemic lupus erythematosus (SLE), relapsing polychondritis (RP) and Sjögren’s syndrome (SS) can be cited. Signs and symptoms such as oral hyposalivation, x...

From the perspective of helping students to alleviate English speaking anxiety, this study proposes emotion regulation as an instructional approach to intervene in the English speaking anxiety of 28 non-English college students, investigates whether emotion regulation instruction can alleviate students’ English speaking anxiety and thus has an impact on oral performance, and examines the relationship between English speaking anxiety and oral performance. The results found that there was a signif...

The geometric characteristics and the construction for cubic indirect Pythagorean-hodograph (indirect-PH) curves are presented in this study. By introducing an auxiliary control point and a parameter respectively, two geometric characteristics in terms of quantities related to Bézier control polygon of the curve are given. Furthermore, based on the derived conditions we provide a new geometric modeling approach for the construction of cubic indirect-PH curves in detail. And at the end of this pa...

Aiming at the problems that the traditional teaching process of “Automatic Test System” course is mainly based on the single teaching of theoretical knowledge, the practice teaching is separated from the engineering reality and the course evaluation is not reasonable, the reform exploration is carried out from the aspects of teachers’ ability, teaching content and evaluation method, combined with the CDIO (Conceiving Designing Implementing and Operating) model and the project teaching concept. F...

The teaching practice and the problems in traditional teaching of principle of single-chip microcomputer and application course are expounded. In order to improve the application ability of students, with the concept of OBE, the integrated teaching mode of theory and practice teaching is adopted. From multiple perspectives, the cultivation of application ability is enhanced through teaching content, teaching methods and assessment methods. Students are encouraged to design independently, and pra...

As the latest one in the field of SLA/FLA motivational study, the theory of DMC(s) is of great significance both theoretically and pedagogically. This current paper aims at whether the core features of tertiary non-English majors’ motivational behaviors in china are in line with those outlined in the theory of DMCs. The results disclose that when the participants experienced a DMC, their goals/visions as the driving force were directed, their learning behaviors with clear start points were recur...

The Udwadia-Kalaba formulation is proposed to model the longitudinal dynamics of a road vehicle. To render complex situations such as spinning on a slippery road, an original approach is implemented by the relaxation of constraints in the Udwadia-Kalaba formulation for the rolling of a wheel. In a combined approach of both slip and stiction in the contact section, the constraints equations of pure rolling are associated with stiction. Such constraints are lifted as slip occurs to allow the dynam...

Background: During off-pump coronary surgery, temporary occlusion of the left anterior descending coronary artery (LAD) is often necessary as a preconditioning method or during the performance of the anastomosis. Our aim is to describe the effect of prolonged and intermittent occlusion of the LAD on the measurement of mean graft flow (MGF) and arterial graft pulsatility index (PI). Methods: Off-pump coronary surgery (internal mammary artery in situ to LAD) was performed on 8 pigs of the Landrace...
