    since more than three centuries ago the classical theory Created equations of accelerated motion, then the theory of relativity came and explained that the classical theory gives erroneous results at very high speeds, But also the special relativity there are no equations of accelerated motion at high speeds too, The equations of this movement remains missing to this days, Today we are finding these equations according to the study previously submitted (II Bulletin) by IISTE. Keywords: Jabr's equations of accelerated motio

    Mickelson held in 1887 and Morley experiment to determine the speed of the earth for the supposed ether, But the classical theory failed to explain this experiment, After the effort was able to interpret the experience, that is design equations  called the Lorenz's transformations, But rejected at the time because it did not conclude mathematically, Then Einstein in 1905 came And was able to interpret the experience as his theory of special relativity that depend entirely on the uniform rectilinear motion ,then Einstein put his transformations. But now we can find these transformations depending on the accelerated motion (Jabr's transformations)! Keyword: Jabr's Transformation

    Einstein the kinetic energy in static case discovered through his theory of special relativity, it was expressed about contain of the material of energy this equation is very important in physics, But today we discover the second static equation of energy It is the potential energy or the internal energy of the Fundamental particles  and the quantity of energy equal the quantity of static kinetic energy to Einstein , But this equation is very important  because it know us at the internal structure , The basic of the material and it is characteristics , such as New forces undiscovered in nature so far and the dimensions of the particles and smaller particles in nature., The previous three bulletins were the entrance to a new physical theory is (recovery Theory of energy) Which we can derive them previous theories such as: Newton's principles - the theory of relativity to Einstein - quantum theory of Max Planck - hypotheses Bohr - Mechanics waveform of Louis de Broglie in addition to other new theories were not known before today.

    The theory of energy recovery is a comprehensive physical theory to a large extent, which derive major theories of physics such as Newton's principles and special and general relativity and quantum theory and Bohr's hypotheses to determine diameters atoms and the theory of mechanics waveform of Louis de Broglie.... The discovery of this theory because of my research on ways to facilitate the understanding of physics for students, being a teacher of this substance, where I noticed alienated by the students for this substance, This research led to the discovery of this theory, which has become today of easy for students to derive and understand any theory of physics from the previous theories, In addition to the discovery of other theories that were not known before today, I believe that this will open new horizons in physics leads to theoretical discoveries and industrial applications contribute to alleviating the suffering of human daily In addition to contributing to the development of all the peoples of the earth, without exception.

    The Development of an Age-Structured Model for Trachoma Transmission Dynamics, Pathogenesis and Control

    Get PDF
    Trachoma is the worldwide leading infectious cause of blindness and is due to repeated conjunctival infection with Chlamydia trachomatis bacteria. The effects of control interventions on population levels of infection and active disease can be promptly measured, but the effects on severe ocular disease outcomes require long-term monitoring. We present a mathematical model of trachoma transmission and disease to predict the impact of interventions on blinding trachoma. The model is based on the concept of multiple re-infections leading to progressive scarring of the eye and the potentially blinding disease sequelae. It includes aspects of trachoma natural history such as an increasing rate of recovery from infection, and a decreasing chlamydial load with subsequent infections. The model reproduces key features of trachoma epidemiology such as the age-profile of infection prevalence; a shift in the prevalence peak toward younger ages in higher-transmission environments; and a rising profile of the prevalence of the severe sequelae (scarring, trichiasis), as well as estimates of the number of infections experienced before these sequelae appear. The model can be used to examine the outcomes of various control strategies on infection and disease and can help to plan treatment interventions for different endemic settings

    Background: Trachoma, the worldwide leading infectious cause of blindness, is due to repeated conjunctival infection with Chlamydia trachomatis. The effects of control interventions on population levels of infection and active disease can be promptly measured, but the effects on severe ocular sequelae require long-term monitoring. We present an age-structured mathematical model of trachoma transmission and disease to predict the impact of interventions on the prevalence of blinding trachoma. Methodology/Principal Findings: The model is based on the concept of multiple reinfections leading to progressive conjunctival scarring, trichiasis, corneal opacity and blindness. It also includes aspects of trachoma natural history, such as an increasing rate of recovery from infection and a decreasing chlamydial load with subsequent infections that depend upon a (presumed) acquired immunity that clears infection with age more rapidly. Parameters were estimated using maximum likelihood by fitting the model to pre-control infection prevalence data from hypo-, meso- and hyperendemic communities from The Gambia and Tanzania. The model reproduces key features of trachoma epidemiology: 1) the age-profile of infection prevalence, which increases to a peak at very young ages and declines at older ages; 2) a shift in this prevalence peak, toward younger ages in higher force of infection environments; 3) a raised overall profile of infection prevalence with higher force o

    Abstract Background Several factors contribute to delayed presentation with ovarian cancer (OC) symptoms including poor symptom awareness and barriers to seeking help. This study explored the anticipated time to seek medical advice for possible OC symptoms and its association with OC symptom awareness. In addition, it examined perceived barriers that may delay help-seeking among Palestinian women. Methods A cross-sectional study was conducted among adult women (≥ 18 years) recruited from hospitals, primary healthcare centers, and public spaces in 11 Palestinian governorates. A modified version of the OC awareness measure was used to collect data in face-to-face interviews. The questionnaire comprised three sections: sociodemographic details, awareness of 11 OC symptoms and time to seek medical advice, and barriers to early presentation. Results Of 6095 participants approached, 5618 completed the OCAM (response rate = 92.1%). The proportion of participants who would immediately seek medical advice for a possible OC symptom varied based on the symptom’s nature. For OC symptoms with pain, the proportion that reported immediate seeking of medical advice ranged from 7.9% for ‘persistent low back pain’ to 13.6% for ‘persistent pain in the pelvis’. For non-specific potential OC symptoms, the proportion that reported immediate seeking of medical advice ranged from 2.3% for ‘feeling full persistently’ to 15.8% for ‘increased abdominal size on most days’. Good OC symptom awareness was associated with higher likelihood of seeking medical advice within a week from recognizing 10 out of 11 OC symptoms. Emotional barriers were the most common barriers with ‘feeling scared’ as the most reported barrier (n = 1512, 52.4%). Displaying good OC symptom awareness was associated with a lower likelihood of reporting ≥ 4 emotional barriers (OR = 0.61, 95% CI: 0.38–0.98). Conclusion Participants with good OC symptom awareness were more likely to seek medical advice earlier and to display fewer emotional barriers. Establishing educational interventions to raise OC awareness may help in promoting earlier help-seeking and, thus, facilitate earlier diagnosis and improved prognosis
