Aim. To determine the sex specificities of medical and social parameters in patients hospitalized due to coronary artery disease (CAD), class II, III, IV angina, aged 35-60 years and assess the significance of their relationship with different levels of depression.Material and methods. The study involved 312 patients aged 35-60 with documented CAD, class II, III, IV angina. Two comparison groups were identified: group I — 138 patients (men, 81; women, 57) with CAD and without depression (mean age, 47,8±4,6 years); group II — 174 patients (men, 60; women, 105) with CAD and depression (mean age, 48,3±5,3 years). Medical and social data, the severity of depression and distress tolerance, psychological status and quality of life was assessed. Statistical analysis was carried out, which are presented as the mean and standard error of the mean (M±m). The odds ratio (OR) and 95% confidence interval (CI) were calculated. Differences were considered significant at p<0,05.Results. The prevalence of depression among patients with CAD was 55,77%, while women were 1,5 times more likely to suffer it than men. Depression was significantly associated with hyperglycemia, hypercholesterolemia, and class III-IV angina, regardless of sex. Class III and IV angina prevailed in women, while class II angina — in men (OR, 2,16; 95% CI, 1,37-3,41, p<0,001)). Women were more prone to degree II-III disability (group II, 26,67%; group I 8,77%; p=0,008), compared with men (group II, 27,54%; group I, 11,11%; p=0,012). Sedentary lifestyle was also associated to a greater extent with the female sex than with the male (OR, 2,89, 95% CI, 1,46-5,70, p=0,003; OR, 2,31, 95% CI, 1,19-4,48; p=0,014, respectively). Both men and women showed a significant association of depression with atherosclerosis (p<0,001), however, sex differences did not reach significance. Indicators such as lack of job and higher education, as well as smoking and arrhythmias were characteristic of both sexes, but had a greater impact on the mental condition of men (p=0,002, p<0,001, p=0,0014 and p=0,01, respectively). For men, the relationship of depression with diabetes (8,7 vs 0%; p=0,008), obesity (42,03 vs 19,75%; p=0,004), subordinate status (82,61 vs 64,2%; p=0,016) and unmarried status (60,87 vs 40,74%; p=0,02).Conclusion. There are significant differences in factors contributing to depression in different sex groups. The association of depression with CAD has an adverse effect on the physical and psychological health of both males and females. At the same time, women are more prone to mental disorders than men. It is necessary to further study the sex characteristics of medical and social parameters in order to personalize treatment methods.

Objective: To evaluate the effectiveness of interscalene brachial plexus block versus combined suprascapular and axillary nerves block for shoulder arthroscopy. Methods: In this prospective study 174 patients were operated on the shoulder joint by the arthroscopic method under combined anesthesia. In the 1st group (n=96), for the purpose of analgesia, patients got interscalene brachial plexus block; in the 2nd group (n=78), patients received suprascapular and axillary nerves block. Ultrasound visualization and neurostimulation were used in both groups. Recorded the time from the start of blockade to the start of the operation, as well as the duration of the sensory and motor blockade. The intensity of postoperative pain was assessed with a 10-point Numeric rating scale, the need for additional analgesia, the quality of night sleep, and patient comfort. Neurological complications were also recorded.
Results: There were no differences in the time from the admit patients to the operating room and before the start surgery. The analgesic effect in the early postoperative period in the 1st group was higher, but by the end of the first day there was no statistical difference between the groups in the intensity of the pain syndrome. Intake of non-narcotic and narcotic analgesics was higher in the 2nd group. Complications were noted only for the 1st group: diaphragm paresis in 6 (6.25%) patients, in 2 (2.08%) recurrent laryngeal nerve blockade. Satisfaction with postoperative analgesia was 100% in patients of the 2nd group. The choice of regional anesthesia for arthroscopic interventions on the shoulder did not affect the length of hospitalization.
Conclusion: Selective anesthesia of the suprascapular and axillary nerves during shoulder arthroscopic surgery is an alternative of interscalene brachial plexus block; it is not associated by respiratory and neurological complications; does not violate movements in the distal upper limb, reduces psychological discomfort and anxiety of patients.
Comment on “Dynamic Tilt Correction Using Direct Rotational Motion Measurements” by Felix Bernauer, Joachim Wassermann, and Heiner Igel
Authors: Graizer Vladimir 
Published: February 2021

AbstractThis article identifies deficiencies in the article of Bernauer et al. (2020) in performing and describing shake table and numerical (synthetic) testing of newly designed seismic instruments for recording complex translational and rotational motion. In my opinion, this is a result from a deficiency in referencing previously published peer-reviewed papers in this area. I also disagree with Bernauer et al. (2020) interpretation of the origin of errors in a vertical sensor’s recording because the sensitivity of a vertical pendulum type sensor to small tilts is much lower than that of the horizontal. Complete differential equations of pendulum-type horizontal and vertical seismometers are presented and examples of previously performed numerical and shake table tests of seismic instruments are shown.

AbstractAs the earliest institute in Turkey dedicated to locating, recording, and archiving earthquakes in the region, the Kandilli Observatory and Earthquake Research Institute (KOERI) has a long history in seismic observation, which dates back to the installation of its first seismometers soon after the devastating Istanbul earthquake of 10 July 1894. For over a century, since the deployment of its first seismometer, the KOERI seismic network has grown steadily in time. In this article, we present the KOERI seismic network facilities as a data center for the seismological community, providing data and services through the European Integrated Data Archive (EIDA) and the Rapid Raw Strong-Motion (RRSM) database, both integrated in the Observatories and Research Facilities for European Seismology (ORFEUS). The objective of this article is to provide an overview of the KOERI seismic services within ORFEUS and to introduce some of the procedures that allow to check the health of the seismic network and the quality of the data recorded at KOERI seismic stations, which are shared through EIDA and RRSM.

AbstractStrong ground motion records and free open access to strong-motion data repositories are fundamental inputs to seismology, engineering seismology, soil dynamics, and earthquake engineering science and practice. This article presents the current status and outlook of the Observatories and Research Facilities for European Seismology (ORFEUS) coordinated strong-motion seismology services, namely the rapid raw strong-motion (RRSM) and the engineering strong-motion (ESM) databases and associated web interfaces and webservices. We compare and discuss the role and use of these two systems using the Mw 6.5 Norcia (Central Italy) earthquake that occurred on 30 October 2016 as an example of a well-recorded earthquake that triggered major interest in the seismological and earthquake engineering communities. The RRSM is a fully automated system for rapid dissemination of earthquake shaking information, whereas the ESM provides quality-checked, manually processed waveforms and reviewed earthquake information. The RRSM uses only data from the European Integrated Waveform Data Archive, whereas the ESM also includes offline data from other sources, such as the ITalian ACcelerometric Archive (ITACA). Advanced software tools are also included in the ESM to allow users to process strong-motion data and to select ground-motion waveform sets for seismic structural analyses. The RRSM and ESM are complementary services designed for a variety of possible stakeholders, ranging from scientists to the educated general public. The RRSM and ESM are developed, organized, and reviewed by selected members of the seismological community in Europe, including strong-motion data providers and expert users. Global access and usage of the data is encouraged. The ESM is presently the reference database for harmonized seismic hazard and risk studies in Europe. ORFEUS strong-motion data are open, “Findable, Accessible, Interoperable, and Reusable,” and accompanied by licensing information. The users are encouraged to properly cite the data providers, using the digital object identifiers of the seismic networks.

“Breast cancer is one of the foremost reasons for cancer death in the fewer developed countries of the world. This is partially because a change in lifestyles it’s affecting growth in occurrence and partially because of clinical advances to combat the disease are not reaching women existing in these regions. Adjuvant radiotherapy given subsequent operation for primary carcinoma of the breast has been revealed to reduce the occurrence of locoregional reappearance from 30% to 10.5% at 20 years and breast cancer deaths by 5.4% at 20 years. 40 patients by initial-stage breast cancer underwent calculated tomography. 2 diverse treatment strategies were created for each patient: the wedge-based (conventional) strategy and the FIF plan. Dosimetric parameters and monitor components were associated with paired sample t-test. FIF technique gained significantly lower dose homogeneity index, lower maximum doses, and higher median doses in PTV (P&#60;0.05). Similarly, the conformity index, and mean doses were higher in the FIF technique but the changes were not significant (P&#62;0.05). In ipsilateral lungs, FIF significantly reduced the maximum and mean doses (P&#60;0.05), and showed a tendency to reduce V20 (P&#62;0.05). In patients with left-sided breast cancer, minimum and maximum doses and V40 of heart were significantly decreased in FIF plans (P&#60;0.05). Doses to the contralateral lungs did not differ significantly. These results along with significantly fewer monitor unit’s essential for therapy in FIF suggest that this technique may be more advantageous during breast irradiation.

Geomechanics Without Sonic In Tight Gas Reservoirs In The North Of Oman

Published: February 2021

Abstract
Barik and Miqrat are the main two deep tight gas clastic reservoirs in several fields of Oman. In the area of the current Study, these reservoirs are encountered at depth 4500-5200 m and contain rich gas/condensate. Average permeability for different units ranges from 0.02 to 4 mD, porosity up to 14% with averages values within the range 5-10%. In order to produce economically, hydraulic fracturing is applied in these reservoirs. Geomechanics calculations are essential for the fracturing design. One of the particular challenges is fracture containment within the gas zone because in view of low stress contrast between different lithologies. Sonic data are normally used for these calculations. However, based on the analysis of the Sonic data available, a simple workflow was developed for Geomechanics calculations which don't require Sonic. A good restoration of compressional Sonic was achieved using the total porosity and the rock volumetrics as the input data. The analysis reveals good correlation between the complex rock constituents and the Poisson's ratio. These findings resulted in good Shear Sonic restoration and fir for purpose calculations of Geomechanics parameters. The Minimum horizontal stress data obtained based on actual Sonic data matches very well with the Minimum horizontal stress derived without Sonic resulting in practically the same hydraulic fracturing design.
The normalization of Gamma Ray and Neutron and rigorous multimineral analysis was a key to success for this methodology. A fit for purpose methodology was developed which enabled to perform identification of 3 key rock constituents even from the basic Triple Combo.
The methodology for Geomechanics without Sonic was used for frac design in several wells. The proposed model is found to be very robust.
Beyond Volumetrics: Unconventional Petrophysics for Efficient Resource Appraisal (Example from the Khazzan Field, Sultanate of Oman)
Authors: Spain David R. , Merletti German D. , Dawson William 
Published: February 2021

Abstract
The Middle East region holds substantial resources of unconventional tight gas and shale gas. The efficient extraction of these resources requires significant technology and expertise across numerous disciplines, including reservoir description and geomechanical characterization, hydraulic fracture modelling and design, advanced numerical simulation capabilities, sensor and surveillance technologies, and tightly integrated workflows.
The effective application of these integrated subsurface and completion workflows leads to improved capital efficiency and well performance through increased well potential, increased ultimate recovery, and reduced costs. Key elements include dynamic rock typing to highlight potential flow units that will maximize gas deliverability, geomechanical modelling to provide a calibrated stress profile, and an integrated model that demonstrates the importance of understanding both dynamic flow properties and geomechanical response in complex tectonic environments.
Dynamic rock typing focuses on using both depositional and petrophysical properties including rock type, porosity, and effective gas permeability at reservoir conditions to divide the reservoir into flow units in the context of their saturation history. The geomechanical profiling generates a tectonics-corrected minimum horizontal stress (SHmin) and the net confining stress (NCS). The rock-log-test calibration requires the evaluation and integration of subsurface fracture tests, including After-Closure Analysis (ACA), Data Fracs and Micro Fracs. All three involve different injection volumes and sampled reservoir volumes.
Tight gas petrophysical studies must go “beyond volumetrics”, and should consider not only the static (storage) and dynamic (flow) properties within the context of the petroleum system and evolution of the current day pore geometry and fluid saturation distribution, but also the geomechanical stress regime and its implications for efficient completion optimization. Alternative interpretations test the range of uncertainty and are useful in designing field trials and surveillance strategies to reduce the subsurface uncertainty and to mitigate development risks.
