Self-Adjointness of Generalized MIC-Kepler System

We have studied the self-adjointness of generalized MIC-Kepler Hamiltonian, obtained from the formally self-adjoint generalized MIC-Kepler Hamiltonian. We have shown that for \tilde l=0, the system admits a 1-parameter family of self-adjoint extensions and for \tilde l \neq 0 but \tilde l <{1/2}, it has also a 1-parameter family of self-adjoint extensions.Comment: 11 pages, Latex, no figur

The Effect of a Frailty Management Program on the Rehabilitation of Elderly Patients after Surgical Treatment

The article performs the results of rehabilitation programs realized among senile patients after videolaparoscopic cholecystectomy, based on specific for geriatrics senile patients’ status assessment methods with determination of frailty and geriatric syndromes exten

Monitoring and Quality Control of Diesel Fraction Production Process

In this work the mathematical model of diesel fraction and atmospheric gasoil catalytic dewaxing process has been developed. Also the pattern of applying the created model to solving such problems as monitoring and quality control of diesel fraction production in the catalytic dewaxing process. It has been represented that to meet such challenges, the model should take into consideration thermodynamic and kinetic laws of hydrocarbon conversion on the catalyst surface, and instability factors that are specified by catalyst deactivation. The developed model allows controlling the quality of obtained diesel fraction depending on feed and temperature regime in the reactor. The value of model calculation absolute error does not exceed 2%, which corroborates the adequacy of the model to actual process. The computations using the model have shown that to provide the desired product yield (not less than 40% wt. of overall yield of the unit products) of programmed quality (cold filtering plugging point not higher than minus 34°C for winter diesel fuels and not lower than minus 40°C for arctic ones) at long-time catalyst operation (during 4 years), it is necessary to sustain the reactor temperature at the average level of 19°C higher than when working with fresh catalyst. This must be done to compensate catalyst activity loss due to its deactivation

Laparoscopic Roux-en-Y reconstruction in a patient with afferent loop syndrome and peptic ulcers of gastroenteroanastomosis - A first experience

This paper is devoted to the description of a currently rare clinical observation of the surgical treatment of a patient with postgastroresection syndrome (afferent loop syndrome and peptic ulcers of gastroenteroanastomosis) - resection of the stomach stump with laparoscopic Roux-en-Y reconstructio

Diagnosis of endometrial hyperplasia in routine gynecological practice

Objective. To estimate the accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) in diagnosis of endometrial hyperplasia using transvaginal ultrasonography (TVS) versus histopathological findings. Materials and methods. This is a retrospective study of 156 patients who underwent hysteroresectoscopy or diagnostic curettage. A comparative analysis of the preoperative diagnosis according to the TVS and postoperative diagnosis according to the histopathological conclusion was performed. All the patients were divided into 2 groups based on the TVS results before the procedure. Group 1 included 71 women with preoperative diagnosis of endometrial hyperplasia. Group 2 consisted of 85 women who underwent hysteroresectoscopy or diagnostic curettage for some other reasons. Using the statistical and mathematical methods, we determined the diagnostic value of TVS for diagnosis of both endometrial hyperplasia and pathology requiring subsequent invasive intervention into the uterine cavity. Results. According to histopathological findings, endometrial hyperplasia was found only in 35 (49.30 % PPV) out of the 71 patients who were positively diagnosed using TVS. The other 36 patients (50.70 %) had a negative histopathological diagnosis. The women of Group 2 were diagnosed correctly (absence of endometrial hyperplasia) in 52 cases (61.18 % NPV), but findings were positive in 33 (38.82 %) women according to histopathological examination. The sensitivity of TVS in the diagnosis of endometrial hyperplasia was 51.47 % (95 %CI 39.03–63.78) and the specificity was 59.09 % (95 %CI 48.09–69.46). However, the absence of indications for invasive intrauterine intervention was observed only in 4.22 % of women in Group 1 and in 2.35 % in Group 2. Conclusions. TVS has a low diagnostic value to identify an endometrial hyperplasia. TVS has a high diagnostic value for determination of intrauterine pathology which requires further hysteroresectoscopy or diagnostic curettage. Low diagnostic value of TVS in the diagnosis of endometrial hyperplasia necessitates an additional analysis considering the qualification of specialists performing ultrasound, the adequacy of the MOH Order No. 676 fulfillment, warranting reflection of parameters such as the endometrium structure, polypoid inclusions, sound conductivity, outer contour of the M-echo and uterine cavity surface as well as the endometrial-uterine ratio calculation in peri-and post-menopausal patients

Automated control system for a mashing process

The goal of this paper is to describe a system for a mashing process, which is the first part of brewing beer. The mashing is a procedure where the fermentable (and some non-fermentable) sugars are extracted from malts. The program part based on LabVIEW, which is used to control NI CompactRIO. The main target of the project is to reach a predefined levels of the temperatures and maintain it during the pauses. When the necessary break time is ended the system is ready to go to the new value. The precise control of the temperatures during the breaks is one of the critical factors that define the texture and alcohol content of the beer. The system has two tanks with resistors PT100 in both of them, heat exchanger (coil), heater and pump. The first tank has heating element in order to rise the temperature in the other one. This project has practical solution with all explanations and graphs which are proven working ability of this control system
