A century ago the classical physics couldn’t explain many atomic physical phenomena. Now the situation has changed. It’s because within the framework of classical physics with the help of Maxwell’s equations we can derive Schrödinger’s equation, which is the foundation of quantum physics. The equations for energy, momentum, frequency and wavelength of the electromagnetic wave in the atom are derived using the model of atom by analogy with the transmission line. The action constant A0 = (μ0/ε0)1/2s02e2 is a key term in the above mentioned equations. Besides the other well-known constants, the only unknown constant in the last expression is a structural constant of the atom s0. We have found that the value of this constant is 8.277 56 and that it shows up as a link between macroscopic and atomic world. After calculating this constant we get the theory of atoms based on Maxwell’s and Lorentz equations only. This theory does not require knowledge of Planck’s constant h, which is replaced with theoretically derived action constant A0, while the replacement for the fine structure constant α-1 is theoretically derived expression 2s02 = 137.036. So, the structural constant s0 replaces both constants h and α. This paper also defines the stationary states of atoms and shows that the maximal atomic number is equal to Zmax = 137. The presented model of the atoms covers three of the four fundamental interactions, namely the electromagnetic, weak and strong interactions.

Application of Maxwell’s equations and the theory of relativity on the processes in atoms with real oscillator leads to the structural constant of atoms s0 = 8.278692517. Measurements show that the ratio of energy of the photon and its frequency is not constant which means that Planck’s h is not constant. The theory which is consistent with these measurements, has been found. This theory covers processes in electron configuration and also at the core of atoms. Based on the structural constant s0 the maximum possible atomic number Z is determined. In order to encompass all atoms and all nuclides a new measurement unit has been proposed. That is the measurement unit for the order of substance. The introduction of structural constant s0 makes 11 fundamental constants redundant, including Planck’s h. The structural constant of atoms s0 stands up as the most stable constant in a very wide range of measurement, so it may replace variable Planck’s h well. Continuity of the bremsstrahlung is explained.

A hydro tunnel in Serbia＇s capitol Belgrade is currently constructed using EPB TBM （earth pressure balance tunneling machine）. To assess the risk of TBM jamming, an analysis is made including calculation of expected ground pressures on the machine and critical frictions and pressures along the route, which could stop the advance due to limitations of the machine. The ground pressures were calculated using 2D plain strain analytical and numerical methods, and using 2D＋ plain strain axisymmetrical numerical method to simulate effects of TBM advance, effects of deformations in front of TBM and effects of rigidity changes in area of TBM shield tail where ground abruptly looses contact with the shield and could additionally deform toward the concrete liner. Calculated deformations and stresses varied along the TBM and concrete liner, with prominent concentrations around the cutter head and TBM shield tail. The results of analytical and numerical calculations were compared and combined to construct diagrams of expected ground pressures on TBM along the tunnel route, and diagrams of critical frictions that may cause the jamming. Based on this analysis and ongoing measurements of ground pressures on TBM, recommendations have been made on excavation regimes, and additional investigations in front of TBM. So far a relatively fair match of the predicted and measured ground pressures on TBM is observed.

Leptospirosis is a life-threatening zoonotic disease of global distribution. It has variable presentation ranging from mild febrile illness to life-threatening complications like acute renal failure, acute hepatic failure, pulmonary hemorrhages and cardiac arrhythmias. Cardiac manifestations of leptospirosis are not uncommon but are underdiagnosed. Cardiac manifestations may vary from minor rhythm abnormalities to fatal ventricular arrhythmias. We report an unusual presentation of leptospirosis in a patient who presented to the Emergency Department with epigastric pain and congestive cardiac failure with rhythm disturbances and selective myocardial involvement mimicking as Non ST elevation Inferior wall myocardial infarction (NSTEMI). The Cardiac manifestations of Leptospirosis need meticulous intensive care management as the mortality rate is very high in this subset of patients. Index suspicion and early treatment remains the mainstay of this life threatening zoonotic disease.

BACKGROUND Leiomyosarcoma(LMS) of the thyroid gland is a rarely presented tumor that offers poor prognosis. To the best of the authors' knowledge, there currently exist only 28 known cases described in the literature(limited to English).CASE SUMMARY Herein a case is reported of a 60-year-old female patient who had an LMS of the thyroid, which was accompanied by periodic dysphonia and breathing disorder as well as the feeling of pressure in the chest and neck. At the time the disease was diagnosed, no metastases were detected. Prior to the diagnosis, the patient experienced a uterine adenocarcinoma that had been treated by surgical procedure and radiotherapy. For the LMS, a total thyroidectomy was performed,followed by radiotherapy. Since metastases were also discovered in the lungs,sternum, and femur, chemotherapy was administered as ***, the tumor cells in the thyroid indicated positively for alpha smooth muscle actin, calponin, and H-caldesmon, but were negative for CD34, p63, estrogen receptor, progesterone receptor, and Epstein-Barr *** Although the etiology of the LMS is as of yet unknown, prior malignancy and radiation should be considered as risk factors.
