Spontaneous utero-rectal fistula formation following reconstructive genital tract surgery: An interesting case report

A genital fistula is an abnormal communication between uterus with either urinary tract or gastrointestinal tract. Although genitourinaryfistula is a common entity, rectovaginal or even uterorectal fistula is relatively uncommon. The etiology of fistula is usually due toan obstetric cause in a developing country, whereas, it is gynecological in the developing country. Whether etiology is obstetricalor gynecological, this develops following days of the procedure. Here, we present the case of a 17-year-old girl, who underwentvaginoplasty for cervical atresia and develop uterorectal fistula one and a half year following the first surgery. She was finallymanaged with hysterectomy

Star Formation Activity in the Galactic HII Complex S255-S257

We present results on the star-formation activity of an optically obscured region containing an embedded cluster (S255-IR) and molecular gas between two evolved HII regions S255 and S257. We have studied the complex using optical, near-infrared (NIR) imaging, optical spectroscopy and radio continnum mapping at 15 GHz, along with Spitzer-IRAC results. It is found that the main exciting sources of the evolved HII regions S255 and S257 and the compact HII regions associated with S255-IR are of O9.5 - B3 V nature, consistent with previous observations. Our NIR observations reveal 109 likely young stellar object (YSO) candidates in an area of ~ 4'.9 x 4'.9 centered on S255-IR, which include 69 new YSO candidates. Our observations increased the number of previously identified YSOs in this region by 32%. To see the global star formation, we constructed the V-I/V diagram for 51 optically identified IRAC YSOs in an area of ~ 13' x 13' centered on S255-IR. We suggest that these YSOs have an approximate age between 0.1 - 4 Myr, indicating a non-coeval star formation. Using spectral energy distribution models, we constrained physical properties and evolutionary status of 31 and 16 YSO candidates outside and inside the gas ridge, respectively. The models suggest that the sources associated within the gas ridge are of younger population (mean age ~ 1.2 Myr) than the sources outside the gas ridge (mean age ~ 2.5 Myr). The positions of the young sources inside the gas ridge at the interface of the HII regions S255 and S257, favor a site of induced star formation.Comment: 46 pages, 14 figures, 5 tables.

The disk-outflow system in the S255IR area of high mass star formation

We report the results of our observations of the S255IR area with the SMA at 1.3 mm in the very extended configuration and at 0.8 mm in the compact configuration as well as with the IRAM-30m at 0.8 mm. The best achieved angular resolution is about 0.4 arcsec. The dust continuum emission and several tens of molecular spectral lines are observed. The majority of the lines is detected only towards the S255IR-SMA1 clump, which represents a rotating structure (probably disk) around the young massive star. The achieved angular resolution is still insufficient for conclusions about Keplerian or non-Keplerian character of the rotation. The temperature of the molecular gas reaches 130-180 K. The size of the clump is about 500 AU. The clump is strongly fragmented as follows from the low beam filling factor. The mass of the hot gas is significantly lower than the mass of the central star. A strong DCN emission near the center of the hot core most probably indicates a presence of a relatively cold ($\lesssim 80$ K) and rather massive clump there. High velocity emission is observed in the CO line as well as in lines of high density tracers HCN, HCO+, CS and other molecules. The outflow morphology obtained from combination of the SMA and IRAM-30m data is significantly different from that derived from the SMA data alone. The CO emission detected with the SMA traces only one boundary of the outflow. The outflow is most probably driven by jet bow shocks created by episodic ejections from the center. We detected a dense high velocity clump associated apparently with one of the bow shocks. The outflow strongly affects the chemical composition of the surrounding medium.Comment: 19 pages, 23 figures, accepted by The Astrophysical Journa

CME Model of DMIMS (DU) Wardha: The 10 Point Action Program for Learning and Quality as the Outcome.

Tremendous advances are taking place in the field of medical sciences, continuously changing the concept, approach to management and the outcome of several diseases. Maintenance of professional competence remains an exercise of lifelong learning and an essential requirement for evidence - based medical practice. This is in essence the concept of Continuing Medical Education (CME). Datta Meghe Institute of Medical Sciences (DMIMS) is established as Deemed University (DU) in 2005.  Since then CME has been a regular experience. To augment the efficacy of these activities University Center named “Center for Health Professionals Education and Research” (CHPER) identified 10 areas to attain the desirable outcome of CME activities held at DMIMS (DU). It offers a simplified and more rational approach to credit based CMEs and accordingly recommendations and actionable strategies are planned.

Features of Criminal Liability of Juvenile Criminals: International Legal and Comparative Analysis

The relevance of the problem under study lies in the fact that the criminal liability of juvenile criminals is one of the most difficult areas of criminal law. Minors, given their physiological, mental, and social characteristics, are considered a separate category of criminals, being one of the most vulnerable segments of the population. Therefore, juvenile delinquency manifests itself not only in causing harm to public relations, the personality of the victim, but also directly to the minor, forming antisocial behaviour in the latter's mind. Considering the above, the problem of the specific features of the criminal liability of minors remains relevant today. The purpose of the study is to analyse the criminal liability of minors from an international legal standpoint, as well as to carry out a comparative analysis of the features of the regulation of criminal liability of minors in different countries of the world. To fully explore the subject matter of the study, a set of general scientific and special methods of cognition was used. In particular, the study used the methods of scientific knowledge, system analysis, scientific abstraction, generalisation, comparison, analysis and synthesis, grouping, formalisation, historical and logical analysis. For example, the leading method was the comparison method, which helped to compare the specific features of practice in other countries of the world in criminal liability of minors. The study analyses the features of the criminal liability of minors, in particular the minimum age of criminal liability, differences between countries in this regard, as well as general international standards

Emission spectra of terahertz quantum cascade laser

We calculated energy levels, wave functions, and energies of radiative transitions in terahertz quantum cascade lasers based on GaAs/Al0.15Ga0.85As heterostructures. Current-voltage characteristics and current dependences of laser radiation intensity were measured, and the maximum operating temperatures reaching 85 K were determined. Radiation spectra of quantum cascade lasers were measured for different temperatures, and the effect of intensity “pumping” from lowfrequency modes to high-frequency modes was found to happen in the case of an increase in the current and time delay of the signal capture, which is explained by heating of the sample during a pulse of the current. Application of the lasers for registration of impurity photoconductivity signals in semiconductor heterostructures was demonstrated

Local-density approximation for exchange energy functional in excited-state density functional theory

An exchange energy functional is proposed and tested for obtaining a class of excited-state energies using density functional formalism. The functional is the excited-state counterpart of the local-density approximation functional for the ground state. It takes care of the state dependence of the energy functional and leads to highly accurate excitation energies

Towards dielectric relaxation at a single molecule scale

Dielectric relaxation lies at the heart of well-established techniques of dielectric spectroscopy essential to diverse fields of research and technology. We report an experimental route for increasing the sensitivity of dielectric spectroscopy ultimately towards the scale of a single molecule. We use the method of radio frequency scanning tunneling microscopy to excite a single molecule junction based on a polar substituted helicene molecule by an electric field oscillating at 2–5 GHz. We detect the dielectric relaxation of the single molecule junction indirectly via its effect of power dissipation, which causes lateral displacement. From our data we determine a corresponding relaxation time of about 300 ps—consistent with literature values of similar helicene derivatives obtained by conventional methods of dielectric spectroscopy.publishedVersio
