The well-being and health of an employee require a work-life balance. Hypertension and stress are intertwined. The health and well-being of employees should be a priority for human resources managers to increase their organizational outcomes. Therefore, ill is the motivation of human resources managers to help employees stay well and have better job commitment, performance, satisfaction, and retention.

Objective. Gross mode, the work climate has been studied as an area inherent in leadership. In the case of the one that is distinguished by its communication and vertical motivation, the work environment has been addressed as a determinant of flexibility in terms of conditions, salaries and benefits. In this regard, the objective of this paper has been to explore the dimensions of climate and labor flexibility in order to establish the dependency relationships between its indicators. Methodology. A non-experimental, cross-sectional and correlational study was carried out with a non-probabilistic sample selection of 300 employees from central Mexico. Results and conclusions. The labor climate determines the flexibility, although the most recent literature warns that rather the climate mediates the relationship between the flexibility policies on staff turnover, the informal salary and the absence of benefits. Research lines are recommended concerning the incidence of leadership styles in the variables in question.

Keywords: flexibility; climate; leadership; rotation; salary

The present attempt is dealing with assessment of cream obtained through the use of black soldier fly meal for the potential of antiaging. Through the use of method of dansyl-chloride- fluorescence, the activity of black soldier fly meal cream (BSFMC) for renewal of the skin was assessed through applications to the layer of stratum-corneum in skin cadaver of human being. The fluorescence of the patches stained with “Dansyl-chloride” in control group took sixty days to disappear. While, the fluorescence of the patches stained with “Dansyl-chloride” in the group treated with the BSFM cream. The t-test shows that increase in skin renewal by investigational cream is significant (at the P<0.05 level of significance). The t-test shows that increase in skin renewal by investigational cream is significant (at the P<0.05 level of significance). Black Soldier Fly Meal (BSFM) derived cream deserves significant antiaging efficiency. Black Soldier Fly Meal (BSFM) derived cream is going to prove to be excellent preparation for antiaging properties. This cream can be used for preventing the symptoms of the aging. Further studies should be made for additional data before practically using the investigational cream.

According to the Georg von Bekesy’s theory of traveling wave, announced in 1928, a sound wave from the eardrum travels to the receptor through the middle ear, cochlear fluids, basilemma and bending of the acoustic cell hairs. An analysis of the mechanisms of transmission of information indicates a large number of problems related to the conveyance of a sound signal traveling this way. Experimental studies corroborate some objections which regard as follows:

Disappearance of the sound wave on the way to the receptor.

Threshold hearing according to this theory, which is impossible due to wave energy disappearance.

Impossible is a resonance of very short audible sounds.

Inertia in the ear, which creates problems in the case of high frequencies.

Resolution of the lowest frequencies according to the wave length.

Calculation of the basilemma’s proper vibrations in line with Bekesy’s theory.

Difference in the wave speed in cochlear fluids and the basilemma.

Amplification of quiet tones, especially multitones.

Time for generating a receptor potential

Lack of transmission of high frequencies after stapedectomy.

Immobilization of the basilemma in a cochlear implant, which does not affect the hearing.

Mechanism of converting the sound wave energy into the receptor potential.

In total, those ambiguities related to the traveling wave theory have led to a new theory of hearing under the name ‘Submolecular Theory of Hearing’. The difference consists in acknowledging another signal path to the receptor, accepting the molecular mechanisms of generating receptor potential without tip-links and amplification of quiet sounds through intercellular transformations.

Historically, one of the major reasons for tooth extractions or tooth loss has been severe periodontitis either acute or chronic A removable partial denture or a complete denture do often presents several problems and can even leads to loss of taste, feeling of premature aging and loss of self confidence.

Maxillary anterior spacing is a common aesthetic concern among patients. Labial frenulum, microdontia, mesiodens, peg shaped lateral incisors, agenesis, cysts, and habits such as finger sucking, tongue thrusting, or lip sucking, dental malformations, genetics, proclinations, dental-skeletal discrepancies, and imperfect coalescence of the interdental septum all contribute to midline diastema. Appropriate technique and material for effective treatment are determined by time, physical, psychological, and financial constraints. In diastema cases, direct composite resins provide the dentist and patient complete control over these limitations and the development of a confident smile. In this case report a midline diastema in the maxillary arch was aesthetically managed with direct composite resin in two appointments.
