We propose the techniques for automatic processing of measurement results in the context of golden (typical) device selection and noise figure measurement. These techniques are for golden (typical) device selection and noise figure measurement processing. Automation of measurement result processing and microwave element modeling speeds up a modeling routine and decreases the risk of possible errors. The techniques are validated through modeling of 0.15 μm GaAs pHEMTs with 4 × 40 μm and 4 × 75 μm total gate widths. Two test amplifiers were designed using the developed models. The amplifier modeling results agree well with measurements which confirms the validity of the proposed techniques. The proposed algorithm is potentially applicable to other circuit types (switches, digital, power amplifiers, mixers, oscillators, etc.) but may require different settings in those cases. However, in the presented work, we validated the algorithm for the linear and low-noise amplifiers only.

Lake Vostok, East Antarctica, represents an extensive water surface at the base of the ice sheet. Snow, ice and atmospheric pressure loads applied anywhere within the lake area produce a hydrostatic response, involving deformations of the ice surface, ice–water interface and particle horizons. A modelling scheme is developed to derive height changes of these surfaces for a given load pattern. It is applied to a series of load scenarios, and predictions based on load fields derived from a regional climate model are compared to observational datasets. Our results show that surface height changes due to snow-buildup anomalies are damped over the lake area, reducing the spatial standard deviation by one-third. The response to air pressure variations, in turn, adds surface height variability. Atmospheric pressure loads may produce height changes of up to $\pm$4 cm at daily resolution, but decay rapidly with integration time. The hydrostatic load response has no significant impact neither on ICESat laser campaign biases determined over the lake area nor on vertical particle movements derived from GNSS observations.

The region of Ridge B in central East Antarctica is one of the last unexplored parts of the continent and, at the same time, ranks among the most promising places to search for Earth's oldest ice. In January 2020, we carried out the first scientific traverse from Russia's Vostok Station to the topographical dome of Ridge B (Dome B, 3807 m above sea level, 79.02°S, 93.69°E). The glaciological programme included continuous snow-radar profiling and geodetic positioning along the traverse's route, installation of snow stakes, measurements of snow density, collection of samples for stable water isotope and chemical analyses and drilling of a 20 m firn core. The first results of the traverse show that the surface mass balance at Dome B (2.28 g cm−2 year−1) is among the lowest in Antarctica. The firn temperature below the layer of annual variations is −58.1 ± 0.2°C. A very low value of heavy water stable isotope content (-58.2‰ for oxygen-18) was discovered at a distance of 170 km from Vostok Station. This work is the first step towards a comprehensive reconnaissance study of the Ridge B area aimed at locating the best site for future deep drilling for the oldest Antarctic ice.

A four-year sky survey with the use of the eROSITA telescope on board the Spektr-RG observatory will provide the best coverage in the soft (0.5–2 keV) and standard (2–10 keV) X-ray ranges, both in terms of sensitivity and angular resolution. We have analysed the possibility of detecting various types of isolated neutron stars with eROSITA. Among already known objects, eROSITA will be able to detect more than 160 pulsars, 21 magnetars, 7 central compact objects, all seven sources of the Magnificent Seven, and two other X-ray isolated neutron stars during the four-year survey mission.

Influence of climatic factors on human’s mental health was research in a lot of studies in the world last years. The aim of this study is identifying a relationship between various climatic factors and the mortality of psychiatric patients in Specialized psychiatric hospital ‘Gornja Toponica’ - Nis, Serbia.

This prospective study was carried out on 53 in-patients suffering from chronic schizophrenia. Before the Risperidone treatment they were on the convenient antipsychotic therapy - haloperidol average doses 9.6 mg pro die, or Fluphenazine average 4.2 mg pro die.

The aim of the study was to follow up therapeutically effects of Risperidone, using PANSS scale for schizophrenia, during two months, by two- weeks visits.

Depression is old as a humanity, it s the disease that has been described in the early days of medical history. Depression is the most common disorder nowadays. Sometimes alcoholism and narcomania can mask depression. The aim of our work was to find out about the efficiency of Trazodon in treating depressive disorder with alcoholics who were treated at the department for alcohol addiction in Special Psychiatric Hospital Gornja Toponica in the period May-October 2007 (18 patients). For our research we used Beck's scale (Beck and associates) to evaluate the degree of depression. The research lasted for six weeks (average length of hospitalization). After the first week of treatment there was a progress concerning sleeping and reduction of anxiety. The anti-depressing score was evident already after two weeks, there also has been a remarkable dropping of the amount on Beck's scale for evaluation of depression. Throughout the research of the efficiency with depression symptomatology, the dayly dosage for alcoholics wasn't over the 200 mg (mostly 150 mg). During 6 weeks of clinical study Trazodon successfully reduced the symptoms of depression in alcohol addicts and after hospitalized treatment significantly helped to maintain abstinency. It was equaly used on young and elderly patients and there haven t been notices of any negative effects.

Schizophrenia remains a severe disorder that is associated with a poor outcome in a large subgroup of patients. Major efforts should be made to improve treatment, especially in the long-term psychopharmacotherapy. In this study, we followed 10 patients on the post- hospital ambulatory treatment with long acting Risperidone (LAR) during the six months period.

We discussed the results according to: age, schizophrenia type, LAR- dose (25 mg, 37.5 mg, 50 mg), relapse with hospitalization, and therapeutically compliance (meaning satisfaction with the therapy and regular two- weeks controls), also the improvement on the CGI score.

The CGI improvement scores were significant, as so as compliance with the therapy. Only two patients have relapsed during the study. These results encourage us to believe that many more patients will benefit from the advantages of a second generation of long acting preparations, like Rispolept Consta is.

Disulfiram is one of most important drug in the treatment of alcoholics. Oral form of disulfiram was found 60 years ago. Subcutaneous form is in use more than 30 years. There are a lot of studies with dilemma is it effective therapy or placebo. We tried to elucidate this problem. We analyzed 36 alcoholics who implanted Disulfiram during one-year (2004.). We follow those patients during next two years (2005. and 2006.). During this more than two years period, 26 patients (72%) were in total abstinence, 6 patients (17%) were in abstinence more than one year and only 4 patients (11%) had abstinence less than one year. Social-demographic characteristics of patients with Disulfiram implant were: age between 31 and 40 years (36%), male (94%), with secondary education (61%), who live in town (53%), married (53%) and with agreement for hospital treatment (high motivation) (69%). We conclude that Disulfiram implant is very effective therapy, because ¾ of all implanted patients have longer abstinence than two years, related the standard oral therapy of Disulfiram (max. 60% patients have abstinence longer than one year).

Little is known about the levels of bully/victim behaviors in schools in Serbia and the aim of the present study was to overview of the extent of bullying in Serbia primary school. Data were collected as part of the school without violence project created by UNICEF. The ultimate goal of the project is to support development of the enabling and stimulative school environment and safe conditions for children learning and development. This study examined the prevalence of being bullied and bullying others among 26947 elementary school children through out Serbia. As part of the larger survey, five questions were asked relating to experience of bullying behaviors and being a victim of such behaviors. The findings suggests that the incidence of school bullying in Serbia is quite high – 67% of children experienced in last three months some form of bulling and 24% of children experienced repeated form of bulling. The most common forms of bulling in schools were name calling (33%), hitting (31%), threatening (21%). Our date point on the need for Increase the awareness of everyone at school toward bullying problems. After identification of a problem next steps should be on the intervention in a timely manner with clear and consistent consequences for the child who is bullying and with support and protection for the child who is being bullied.

Electroshock therapy is in fashion again, but modern psychiatry for this kind of treating is using up to date instruments and methods. Half a century ago this procedure was used for healing serious depression, but was substituted with pharmacotherapy due to side effects like short or long time lost of memory.

Today we have modern technology (ECT with pulse electricity), so side effects are milder, and effects of therapy are better.

With this work we want to present the latest concepts in use of ECT therapy and to present our modest, one year long experience in this area.

We also started prophylactic ECT therapy (in imitation on Military medical academy Belgrade), since we was forced to accept already started treatment some of our patients in above mentioned institution.

We will try to demonstrate this problem using the case of a patient who has a number of symptoms which are all related to different diagnoses.

We will describe a patient with a difficult life story which started in his early youth and which could potentially be the cause of his personality disorder, borderline, showing some symptoms of schizoid and compulsive personality disorder and recurrent depressive disorder which developed later in life. Some authors claim that when borderline personality disorder and depressive disorder are comorbid, they are sometimes not dependent upon each other during treatment, but more often improvements in depressive disorder are related to improvements in borderline personality disorder. Some authors have tested the hypothesis that in the population of older patients with depressive disorder, those with personality disorder who developed depression earlier in life (before 18 years of age) prevail in comparison with those who developed depression later. the problem with this patient is that he shows some traits characteristic of personality disorders from all 3 groups. the method used for treating this patient consists of using pharmacotherapeutic measures to treat the symptoms of depression, and psychotherapeutic approach for treating personality disorder (disorders).

In this text we are showing a patient with a very complex “life story”, dominated by extreme difficulties in the developmental period, strong family complications and personal problems, which probably significantly influenced the development of later psychological difficulties. The clinical picture is dominated by symptoms of borderline personality disorder (BPD), but also shows symptoms that would fall under bipolar affective disorder (BD) and cyclothymia. During the screening of the patient and during treatment, we tried to resolve the resulting diagnostic dilemma. Some authors even believe that BPD falls into the BD spectrum of disorders, whereas others insist on the viewpoint that it is a comorbidity of two separate entities. For clinical practice, the important fact is that BD and BPD multiplies the risk of suicidal patients, which requires prompt and adequate combined treatment. The primary psychopharmacological methods are used for BD, while primary psychotherapeutic treatment is used for BPD.

In this study, we’ll in detail deal with the comorbidity of BD and BPD, which are becoming more frequent psychiatric comorbidities, while emphasizing individual and integrative psychopharmacological therapies as the only approach that can act on several factors and ensure the best possible treatment outcome.
