Authors: Shatokhin Vladimir , Granko Boris , Sobol Vladimir 
Published: September 2022

Problem. At present, peristaltic pumps are widely used in construction, chemical production, mining industry, processing plants, food processing industry, etc. The creation of such devices and methods for the rational choice of their parameters is a vital task. One of the effective directions of its solution is the adequate dynamic process modeling in indicated mechanisms. Goal. The work is devoted to the creation of a universal mathematical model of dynamic processes in a peristaltic pump with a hydraulic drive for determining the technological qualities of the device, and the choice of its rational parameters. The model contains the primary geometric of the rotor, mass characteristics, the hydraulic motor dynamic characteristics, the parameters of the hose, and the mixture that is moving. Methodology. The procedure for the generation of Lagrange equations of the second kind was used for building a mathematical model of dynamic processes in the device. The model has been created in the form of a differential equation concerning the rotor angle of rotation. A method has been developed for forming the resistance moment to the pump rotor spinning from the rollers that deform the hose. A non-linear model of drag forces to the mixture movement, which is the Bingham fluid, is obtained by using the Buckingham equation. An expression is found for the drag forces due to the gravity forces of the mixture particles in the hose discharge part. An approach has been suggested to the usage of the catalog data for representing a hydraulic motor torque as an angular velocity function of its rotor . Results. Important technological features of the device operation have been established: the presence of a significant variable component in the mixture motion speed; the influence of the lift height hose length, coefficients of rolling friction for rollers, plastic viscosity, and yield strength in mixture motion speed and pump capacity. Originality. Important technological regularities of the device functioning were established: the speed of the mixture motion can have a significant variable component; the speed of the mixture motion and pump’s performance increase with a decrease in the length of the discharge hose and a decrease in its height, a decrease in the rolling friction coefficients for the rollers and a rejection of side rollers. Practical value. The results of using the developed method for studying dynamic processes were presented when a real construction of a peristaltic pump was being created. The suggested approach is high-potential for the modernization of existing and the development of new models of peristaltic pumps.

Authors: Dmitrik Vitaly , Syrenko Tatyana 
Published: September 2022

Problem. It is necessary to study the relationship of the structure of welded joints with the development of porosity to further obtain such structure, which is characterized by increased resistance to vapor formation. Goal. Study of the peculiarities of nulceation of pores in the metal of welded joints from heat-resistant perlite steels operating in creep conditions to reduce the intensity of pore formation. Methodology. The structure of the metal of welded joints was studied using a macrostructural, microstructural, electron-microscopic, micro-X-spectral and radiographic method. The process of formation of micropores and microcracks was carried out by using electron and light microscopy. Carbide phases were studied by analysis of precipitation using the method of photometry. Results. It was found that creep at welded joints above 270000ch are initially born at the grain limit α – phase – coagulation carbide, and that the pore size of 0.03-0.07 μm, can be considered critical, which is confirmed by an intense increase in their size when working welded joints above 270000. Originality The formation of micropores in heat-resistant pearl steels, during long-term operation in creep conditions, is due to the compatible course of diffusion and deformation processes. Such processes in welded joints are due to their much greater structural heterogeneity. Practical value. In the practical plane, the task is to slow down the processes of deformation and diffusion in both steels and welded joints — by obtaining an initial structure with improved qualitative characteristics.

Background: Anesthesia as a distinct specialty has evolved much beyond the boundaries of operation theater but the services are yet under-recognized. This may be partly because of the lack of knowledge about anesthesia and anesthesiologist in general public and also due to lack of effort to raise awareness among the general public. This study was done to assess the knowledge and perception about anesthesia and anesthesiologist in patients undergoing surgery in Nepal.
Material and Methods: A total of 719 patients scheduled for elective or emergency surgery in eight hospitals of Nepal were consecutively recruited and interviewed using questionnaire at pre-operative period before evaluation by anesthesiologist or anesthesiology resident. Individual response to each question was graded using three point scale.
Results: The age of the patients ranged from 16 to 87 with a mean of 39.5±15.7 years. Only 31.6% and 28.2% had previous surgery and anesthetic exposure respectively. The majority (69.4% and 49.8% respectively) had good knowledge about health care workers present in operation theater and the ones delivering anesthesia. However, knowledge about anesthesia types and anesthetic agents was poor in 48.4% and 51.9% respectively. The knowledge was poor about person responsible for monitoring and maintaining homeostasis (49%), person responsible for resuscitation (46.5%) and management of anesthesia related complications (49.5%). Remarkably, 48.3% of the respondents had average knowledge about who manages post-operative pain. The mean knowledge score for individual patient was calculated and, 11.1%, 83.4% and 5.4% had poor, average and good knowledge respectively.
Conclusion: Majority of patients undergoing surgery had average knowledge and perception about anesthesia and anesthesiologist.

Published: September 2022

Background: Gallbladder adenocarcinoma is the most common malignant tumor of the biliary tract. Most of gall bladder cancers are detected incidentally only after pathological examination of the excised surgical specimens. In this study we investigated the characteristics of incidental gallbladder cancers in our center.
Material & methods: We retrospectively reviewed all of the cholecystectomy specimens in sent for histopathology following laparoscopic cholecystectomy in the study period from January 2015 to October 2019. Clinicopathological characteristics were extracted from the patients' clinical charts, which included symptoms, radiological findings, laboratory data, and surgical procedures as well as outcome.
Results: We identified 6 cases of incidental gall bladder cancer, consisting of 4 women and 2 men ranging in age from 28 to 77 years (mean age 60.5 after pathological study of 1530 resected gall bladders. Out of the 6 cases, 1 case was carcinoma in situ of gall bladder, 1 was T1b and other 4 cases were T2 carcinoma.
Conclusions: The rate of incidental gallbladder carcinoma in our study was 0.39%. This lower incidence could in part be due to increasing use of routine laparoscopic cholecystectomy for symptomatic gallbladder. This strategy of increased early intervention further adds to the advantage of higher chances of gallbladder cancer detection in early stages, and thus better prognosis.
Ambedkar's Nationalism
Authors: Lakhera Pankaj 
Published: September 2022

The idea of nationalism is a modern idea which has its roots in modern European Renaissance. However, in a country like India, it emerged and developed during the anti-colonial struggle which marks a new beginning of social and political awakening. Generally, we identify Indian nationalism with the ideas of great freedom fighters like Gandhi, Nehru, Subhash, Patel and lokmanya tilak. These great leaders emphasized upon a particular brand of Indian nationalism that looks at Indian civilization as the greatest Civilization on earth. It ignores the operation and suppression of Dalits and other down roden sections of Indian society which has been going on in India for centuries. The dominant Indian nationalism is the based upon the ideas of Brahmanism, manuvad and Aryan racial superiority. It bypasses the nationalist perspectives of Dravidians, communist and the subalterns. It was doctor BR Ambedkar who gave a new definition of Indian nationalism. His nationalism stands for the salvation of Dalits and backward sections of Indian society. The present paper will analyse Ambedkar’s ideas on Indian nationalism and will differentiate it from other brands of nationalism prevailing in India for the last two centuries.

Abstract in Hindi Language:
राष्ट्रवाद का विचार एक आधुनिक विचार है जिसकी जड़ें आधुनिक यूरोपीय पुनर्जागरण में हैं। हालाँकि, भारत जैसे देश में, यह उपनिवेश विरोधी संघर्ष के दौरान उभरा और विकसित हुआ जो सामाजिक और राजनीतिक जागरण की एक नई शुरुआत का प्रतीक है। आम तौर पर, हम भारतीय राष्ट्रवाद की पहचान गांधी, नेहरू, सुभाष, पटेल और लोकमान्य तिलक जैसे महान स्वतंत्रता सेनानियों के विचारों से करते हैं। इन महान नेताओं ने भारतीय राष्ट्रवाद के एक विशेष प्रकार पर जोर दिया जो भारतीय सभ्यता को पृथ्वी पर सबसे बड़ी सभ्यता के रूप में देखता है। यह दलितों और भारतीय समाज के अन्य दबे कुचले वर्गों के संचालन और दमन की उपेक्षा करता है जो सदियों से भारत में चल रहा है। प्रमुख भारतीय राष्ट्रवाद ब्राह्मणवाद, मनुवाद और आर्य नस्लीय श्रेष्ठता के विचारों पर आधारित है। यह द्रविड़ों, कम्युनिस्टों और निम्नवर्गों के राष्ट्रवादी दृष्टिकोणों को पारित करता है। डॉक्टर बीआर अंबेडकर ही थे जिन्होंने भारतीय राष्ट्रवाद की नई परिभाषा दी। उनका राष्ट्रवाद भारतीय समाज के दलितों और पिछड़े वर्गों के उद्धार के लिए खड़ा है। वर्तमान पेपर भारतीय राष्ट्रवाद पर अम्बेडकर के विचारों का विश्लेषण करेगा और इसे पिछली दो शताब्दियों से भारत में प्रचलित राष्ट्रवाद के अन्य प्रकारों से अलग करेगा।

A pesquisa utilizou uma rotina de confecção de rede de drenagem por meio de Sistemas de Informações Geográficas para detecção e dimensionamento de erosões lineares em área de pastagem degradada, a partir de imagens derivadas de um drone. Numa área de pastagem de 77 hectares, situada em Rondonópolis, Mato Grosso, no bioma Cerrado, a partir de missões com RPA foi possível a captura de 478 imagens aéreas com alta resolução espacial (2cm por pixel), que foram processadas para a geração de um ortomosaico de fotografias aéreas, e confecção do Modelo Digital de Elevação - MDE. Na sequência, por meio do MDE houve a extração da rede de drenagem, incluindo a formação de ravinas no terreno, que, quando confrontado com a inspeção do mosaico, permitiu a identificação de processos erosivos lineares. Foram identificados 7 processos erosivos, que possuíam área média de 1.473 m2. O uso das ferramentas de hidrologia no processamento do MDE evidenciou os processos erosivos da área, classificando-os como rede de drenagem e a sobreposição das curvas de nível permitiu observar a direção de evolução desses impactos. A junção dessas análises favoreceu uma análise individual de cada processo erosivo, facilitando assim o planejamento particularizado de medidas e intervenção individualizada.

Identification of erosion processes through hydrological models and high resolution aerial images

ABSTRACT: The research used a routine of making a drainage network through Geographic Information Systems for detection and dimensioning of linear erosions in a degraded pasture area, from images derived from a drone. In a pasture area of ​​77 hectares, located in Rondonópolis, Mato Grosso, in the Cerrado biome, from RPA missions it was possible to capture 478 aerial images with high spatial resolution (2cm per pixel), which were processed to generate an orthomosaic of aerial photographs, and creation of the Digital Elevation Model - MDE. Subsequently, through the MDE, the drainage network was extracted, including the formation of ravines on the ground, which, when confronted with the inspection of the mosaic, allowed the identification of linear erosive processes. Seven erosive processes were identified, which had an average area of ​​1,473 m2. The use of hydrology tools in the MDE processing evidenced the erosive processes in the area, classifying them as a drainage network and the superposition of the contour lines made it possible to observe the direction of evolution of these impacts. The combination of these analyzes favored an individual analysis of each erosive process, thus facilitating the individualized planning of measures and individualized intervention.

Nerve transfers for brachial plexus injuries: grading of volitional control
Authors: Socolovsky Mariano , Barillaro Karina , Bonilla Gonzalo , Masi Gilda Di , Malessy Martijn 
Published: September 2022

OBJECTIVE
After brachial plexus injuries (BPIs), nerve transfers are used to restore lost muscle function. Brain plasticity underlies the process of regaining volitional control, which encompasses disconnection of the original donor nerve–related programs and reconnection to acceptor nerve programs. To the authors’ knowledge, the levels of disconnection and reconnection have never been studied systematically. In this study, the authors developed a novel 4-point plasticity grading scale (PGS) and assessed the degree of volitional control achieved, identifying clinical correlations with this score.

METHODS
Patients with BPI who underwent a phrenic, spinal accessory, median, and/or ulnar fascicle nerve transfer to restore biceps and deltoid function were asked to maximally contract their target muscle as follows: 1) by using only the donor nerve program, and 2) by activating the target muscle while consciously trying to avoid using the donor nerve, with assessment each time of the Medical Research Council (MRC) scale grade for muscle strength. The authors’ PGS was used to rate the level of volitional control achieved. PGS grade 1 represented the lowest independent volitional control, with MRC grade 4 obtained in response to the donor command and MRC grade 0 in response to the acceptor command (minimum brain plasticity), whereas PGS grade 4 was no noticeable contraction in response to the donor command and MRC grade 4 in response to the acceptor command (maximum brain plasticity).

RESULTS
In total, 153 patients were studied. For biceps restoration, the phrenic nerve was used as a donor in 44 patients, the spinal accessory nerve in 40 patients, and the median and/or ulnar fascicles in 44 patients. A triceps branch was used to restore deltoid function in 25 patients. The level of volitional control achieved was PGS grade 1 in 1 patient (0.6%), grade 2 in 21 patients (13.7%), grade 3 in 103 patients (67.3%), and grade 4 in 28 patients (18.3%). The median PGS grade did not differ significantly between the four donor nerves. No correlations were observed between age, time from BPI to surgery, duration of follow-up, or compliance with rehabilitation and PGS grade.

CONCLUSIONS
Just around 20% of the authors’ patients developed a complete disconnection of the donor program along with complete independent control over the reinnervated muscle. Incomplete disconnection was present in the vast majority of the patients, and the level of disconnection and control was poor in approximately 15% of patients. Brain plasticity underlies patient ability to regain volitional control after a nerve transfer, but this capacity is limited.

Prezentowany tekst zawiera przekład trzech listów, które w pierwszej połowie VII w. merowińska arystokratka Herchenefreda napisała do swojego syna Dezyderego, wpływowego możnego i przyszłego biskupa Cahors. Przekład poprzedzony został wstępem, w którym czytelnik odnajdzie szkicowo zarysowany kontekst epoki, informacje na temat życia Herchenefredy oraz Dezyderego, a także tematykę poszczególnych listów. Korespondencja merowińskiej arystokratki ostatecznie znalazła się w anonimowych dziejach świętego Dezyderego i w ten sposób także ocalała od zapomnienia. Niekwestionowanie ubogaca ona zasobną merowińską tradycję epistolarną. Przede wszystkim z uwagi na samą autorkę – świecką możną - która w tak przeważającym gronie współczesnych jej męskich twórców pretenduje do miana rara avis. Zwraca uwagę także osobisty i emocjonalny ton omawianej matczynej korespondencji. Listy są ważnym świadectwem wczesnośredniowiecznych relacji rodzicielskich, statusu szlachetnie urodzonych matron, ich wykształcenia oraz powinności względem rodu, męża, synów i wreszcie także całej chrześcijańskiej wspólnoty.

The article analyzes the world experience of parking design, examines examples of parking facilities in economically developed countries in Europe and the United States. Four parking buildings, which differ in design solutions and play different architectural roles in the environment, were analyzed in detail. This indicates the direct impact of the surrounding space and context on the design of new buildings and car parkings in particular.
The analysis was performed on the three-dimensional, architectural planning and compositional-aesthetic characteristics, resulting in features and successful design solutions were highlighted. These examples of foreign experience in parking design were considered in particular in the context of the existing urban environment: an analysis of the new buildings impact on the overall perception of space and the harmony of intervention in the environment is carried out. Generalizations were made on the basis of the analysis, as a result, the features of modern design of parking lots in the urban environment were highlighted.
The obtained results indicate broad perspectives and opportunities for the design of such facilities in Ukraine. In particular, the analysis of designing quality parkings is important for Lviv, where citizens face new problems every day due to growing urbanization and historical preconditions, such as constant lack of parking spaces, chaotic parked cars on streets and pedestrian zones, traffic congestion, reduction level of mobility of citizens and related. The analysis also highlighted the most important aspects to consider at the parking project stage. It will help Ukrainian architects to make the most relevant and harmonious spatial and architectural planning and compositional-aesthetic decisions, creating new parking facilities in Ukraine.

The war in Ukraine is shown complete inability to ensure protection civil population. The current legislation and building codes on engineering and technical measures of civil protection weren’t provided by the realities of war.
The experience of Israel and Singapore in creating safe rooms directly in residential buildings has been analyzing.
The purpose of this researching is discovering inability to modern requirements for current standard codes due to ensuring of civil protection population.
For achievement to purpose was defended following tasks: the experience of something country in ensuring of civil protection population is analyzed, adding to change to the current edition of the State Building Regulations is offered.
In the most amount of Ukraine's residential buildings, there are no safe areas within apartments that can protect the population during rocket attacks and bombardments.
A fundamental scheme of a multi-storey building resistant to destruction and the creation of a protected space within residential buildings is proposed in Ukraine. Examples of the using of this scheme for the organization of safe zones for existing projects of residential buildings are given.
Main requirements of adding to change to the current edition of the State Building Regulations to chapter to ensuring civil protection population is made:
Basic requirements have been developed for adding to change by state building codes in terms of ensuring civil protection of the population: building structures must be designed for resistance to local destruction; escape routes stairs and elevator shafts must be reliably protected from damage and destruction; when developing projects of residential buildings inside an apartment or floor, protection zones should be provided.
