Before the great journey: Plast in Germany in the second half of the 1940s
Authors: Perga Tetiana
Published: November 2020

This article examines the revival of the Ukrainian youth organization Plast in Germany in the first years after World War II. The reasons for this process have been studied. It was found that the establishing of Plast groups in di-pi camps was a spontaneous process, so Union of Ukrainian Plast Emigrants – SUPE was revived for the management of these activities and preventing of moral and physical degradation of Ukrainians. Number of meetings of the organization took place in 1946-1948 under its leadership. The most important were following: the Congress in Karlsfeld in April 1946, the meeting in Mittenwald in July 1947, and the First Ideological Plast Congress held in Ashschaffenburg in March 1948. The organizational and ideological background of Plast’ activities in the first postwar decades were adopted during these meetings. The article analyzes the ideas on the Educational Ideal of the Young Ukrainian and the principles of building further organization’ activities, in particular: apoliticalness, catholicity, acceptance of youth and senior Ukrainians without distinction of an origin and religion, using the ideas of world scouting and readiness to cooperate with other scout organizations, attention to the essence and spirit of the Plast idea and the development of propaganda among “ours”, and “of that which is not”. It was found that the 35th anniversary of the Plast establishment was celebrated in 1947–1948. However meetings of this period were dedicated not only to the summing up of the activities since its establishing. Given the fact that they took place on the eve of the mass resettlement of Ukrainians to other countries – the United States, Canada, Australia, etc., they aimed at developing the main directions of activities of the Plast members in emigration. The article explores the main achievements of the Congress held in 1948 under the slogan “On a further journey to the great purpose”. It is concluded that they were following: the election of the Main Plast Council headed by Plast Head (known as “Nachalniy Plastun”) Severin Levitsky, discussion of external and internal environment in the countries of new living and short-term prospects of this “journey”.

Giriş ve Amaç: Kolorektal kanserler dünyada ve ülkemizde en sık görülen kanserlerdendir ve çok büyük oranda kolorektal poliplerinden gelişirler. Biz bu denli önem arz eden poliplerin ünitemizdeki prevalansını, endoskopik ve histolojik özelliklerini ortaya koymayı amaçladık. Gereç ve Yöntem: 2016-2019 yılları arasında gastroenteroloji ünitesi endoskopi laboratuvarımızda erişkin hastalara, herhangi bir nedenle yapılmış olan kolonoskopik incelemeler etik kurul onayı alınarak retrsopektif olarak tarandı. Kolonoskopik işlemlerde rastlanıp snare ya da forseps yardımı ile polipektomi uygulanan ya da biyopsi alınan polipler ayrılarak , bu poliplerin endoskopik (lokalizasyonu, boyutu, sayısı) ve histolojik (histopatolojik tanı, displazi, kanser) özellikleri incelendi. Elde edilen veriler IBM SPSS 22.0 istatistik programında analiz edildi. Bulgular: Çalışmamızda 2068 hastaya ait işlemlerin 362’sinde (%17.50) polip ya da poliplere rastlanılmıştı. Polip saptanan hastaların yaş ortalaması 59.86±11 (19-92) yıl, erkeklerin yaş ortalaması 60.36 yıl, kadınların yaş ortalaması 59.16 yıldı. Vakaların 236’sı (%65) erkek, 126’sı (%35) kadındı. Çalışmamızda poliplerin boyutlarına göre dağılımı; 298 (%66.81) diminutif polip, 117 (%26.23) küçük polip, 31 (%6.95) büyük polip olarak saptandı. En fazla sayıda polip görülen lokalizasyon sigmoid kolon (n=158, %35.42), en az sayıda polip görülen lokalizasyon ise çekumdu (n=11, %2.46). Çalışmamızda histolojik olarak polipler neoplastik (n=270, %60.54) ve non neoplastik (n=179, %39.46) olarak iki ana grupta incelendi. En sık görülen histolojik tanı neoplastik polipler grubundan adenomlardı (n=254, %56.95), adenomlar içinde en sık tübüler adenomlar (n=222, %87.40) görülmekteydi. Adenomlardan sonra en sık görülen tanı ise hiperplastik poliplerdi (n=131, %29.4). Poliplerin displazi/kanser özellikleri gözden geçirildiğinde 246 (%55.16) polipte düşük dereceli displazi, 6 (%1.35) polipte yüksek dereceli displazi, 1 (%0.22) polipte intramukozal adenokarsinom saptandı. Proksimal kolona doğru gidildikçe poliplerin neoplastik özellikleri artmaktaydı. Sonuç: Çalışmamız yakın zamanda yapılmış güncel kolon polip prevalans çalışmaları ile karşılaştırılarak yapıldı. Çalışmamızda ülkemiz oranlarına yakın kolorektal polip prevalansının yanısıra benzer çalışmalara göre displastik özellikler içeren polip sıklığımızın fazla oluşu dikkat çekiciydi. Bu durum kolonoskopik tarama ve takip programlarına verilmesi gereken önemi ve özeni bir kez daha göstermekteydi.

Authors: HN Mai , YS Lee
Published: November 2020

The proinflammatory cytokines may mediate myocardial dysfunction associated with myocardial injury and inflammatory response is an important process during the pathogenesis of myocardial I/R injury. IL-27, this cytokine is mainly produced by cells of myeloid origin such as monocytes, macrophages, dendritic cells, and microglial cells, in response to stimuli acting through Toll-like receptors. The objective of present study is to assess whether IL-27 can improve ventricular function after myocardial ischemia by down-regulation of inflammatory response. The results demonstrated that the IL-27 markedly attenuated Left Ventricular Function (LVF) in mice model, and reduced plasma level of cTn-I as marker of cardiac injury. Moreover, the IL-27 was associated with up-regulation in both chemokine and cytokines expression following I/R, through down-regulation of activation of JAK/STAT pathway.

Published: November 2020

Background: Hemiplegic shoulder subluxation is one of the most common factor for post-stroke upper limb disability. There are various ways to assess its outcome during rehabilitation, but the assessment of patients’ satisfaction with the shoulder support is often missed. This study was done to compare those patients’ satisfaction with clinical outcome who were undergoing same rehabilitation programme for their hemiplegic shoulder subluxation with and without Bobath shoulder sling.Methods: This prospective controlled interventional study was conducted on 30 patients of both sexes within the age group of 45-65 years with hemiplegic (duration <6 weeks) gleno-humeral subluxation (GHS). Screening of GHS was done by palpation. They were randomly divided in two groups of same number (15 in each group) and put on rehabilitation protocol with group 1 receiving Bobath shoulder Sling as support for subluxed shoulder and group 2 continuing without it. Patients’ satisfaction on clinical outcome was measured with clinical global impression-improvement (CGI-I) scale. Data were collected at 6 weeks (first follow up-visit), 12 weeks (visit 2) and at the end of the study i.e. 24 weeks (visit 3).Results: Statistically significant difference (p=0.003) in mean score of CGI-I at visit 1 suggested significant improvement for group 1 but no statistically significant difference in improvement was noticed between the groups at visit 2 (p=1.000) and visit 3 (p=0.724).Conclusions: Use of support for hemiplegic shoulder is beneficial only during early days of rehabilitation, not on prolonged use.

Published: November 2020

Background: Tonsillectomy is the oldest surgery performed by otorhinolaryngologists worldwide. Through ages different techniques have been tried to improve the post surgical outcome and reduce morbidity among patients. Aim of the current study was to compare the post-operative pain among the patients undergoing tonsillectomy by cold dissection, bipolar cautery dissection and coblation dissection.

Methods: 142 Patients undergoing tonsillectomy in ENT department of TMMC during the period of 3 year were included in the study. Patients were randomly distributed to undergo different techniques of tonsillectomy. The post-operative pain in patients was assessed using the pre-standardized visual analogue pain scale and results were analyzed.

Results: No statistically significant difference was found among the groups undergoing tonsillectomy by cold dissection, bipolar dissection and coblator dissection as the p>0.05. The immediate post-operative pain was found to be slightly higher among the group undergoing tonsillectomy by coblator dissection and the analgesics dose needed in the post-operative period remained the same for all for patients of all the three groups.

Conclusions: No statistically significant difference was found in the post-operative pain scores of patients undergoing tonsillectomy by CD, BD and CBD techniques.

Published: November 2020

Root resorption is the loss of apical root tissue which is implicated by decrease in root-crown ratio. It usually effects from external surface to pulp chamber if not identified in the early stage. Several natural conditions place roots at risk of resorption without any pathology. Knowing the pressure or etiology of the resorption will help the orthodontist in the treatment aspect. To date literature regarding root resorption due to various malocclusions is deplete in Indian population.

To measure and assess the root crown ratios of maxillary incisors with vertical malocclusions, deleterious habits, and validate by two different radiographic techniques.

90 Patients enrolled for the orthodontic treatment were allocated to three groups - open bite, deep bite & control groups and were subdivided based on nail biting habit. Panoramic radiographs, Periapical radiographs (by paralleling technique) for maxillary incisors (360 teeth) were taken and traced. Length of the root & crown were assessed and root crown ratios were calculated and the results substituted to statistics using SPSS.

Comparison of Root-crown ratios in vertical malocclusions, revealed statistically significant (P < 0.001) differences in Open bite group for all maxillary incisors in both panoramic and periapical radiographs. No statistical significant differences were found in the deep bite group. Significant association was found between nail biting habit and Root-crown ratio. Gender predilection was found to be absent.

Decreased Root- crown ratios were observed in open bite patients. Nail biting patients show significant root resorption. Both panoramic radiographs and periapical radiographs with paralleling technique can be used for assessing root resorption.

Published: November 2020

During orthodontic treatment it is crucial to prevent the unintentional movement of the anchorage unit whilst causing movement of other teeth. Conventional methods of anchorage control came along with many shortcomings. The introduction of skeletal anchorage in the form of temporary anchorage devices (TADs) or miniscrews has greatly benefited orthodontists in finding a way of anchorage control with minimum patient compliance and without a complicated clinical insertion and removal procedures. This review article outlines about the types of TADs, parts, techniques of insertion and removal and its clinical applications in orthodontics.

Published: November 2020

Targeting the carbonate-dominated catchment of Xiangxi River, the first tributary of Three Gorges Reservoir, this paper explores the spatiotemporal distribution of stable isotopes in the stream water, and distinguishes the water sources and recharge processes in the river basin. Multiple water samples were collected from the catchments of the main tributaries of Xiangxi River, namely, Nanyang River and Gaolan River. The results show that the two tributary catchments had obvious spatial and seasonable variability in δ18O and δD. This is attributable to the seasonal changes in meteoric precipitation recharge, which depends on ambient temperature, precipitation, evaporation, and secondary evaporation of raindrops. Besides, there is a strong elevation effect on stable isotopes in stream water. In the samples from Gaolan River, the mean elevation effect on the δ18O and δD was -0.35‰, and -1.57‰ per 100m change in elevation in summer, and -0.12‰, and -1.19‰ per 100m change in elevation in winter, respectively. In the samples from Nanyang River, the mean elevation effect on the δ18O and δD was -0.14‰ and -0.89‰ per 100m change in elevation in summer, and -0.08‰ and -0.66‰ per 100m change in elevation in winter, respectively. The δD, δ18O, and deuterium excess (d-value) are not only affected by the elevation effect, but also by the seasonal effect in the study area. The seasonal variations and spatial changes in the tributary catchments reveal the difference between the two catchments in control factors like latitude effect, evaporation, and the mixing of different water sources.

Published: November 2020

Passive acoustic technology (PAT) is an important tool to acquire the passive acoustic signals from marine organisms. In this paper, PAT fish detection is introduced at great length, including the relevant instruments, signal processing methods, and workflow. Focusing on the key tasks of PAT fish detection, the authors proposed a sparse decomposition algorithm that extracts coherent ratio of passive fish acoustic signal, and designed a feature extraction method for that signal based on speech imitation technology. Experimental results demonstrate that the proposed sparse decomposition algorithm can detect fish acoustic signal accurately at low signal-to-noise ratios (SNRs), and the proposed feature extraction method can effectively extract fish acoustic signals from the marine background. The research results shed important new light on the protection and management of fishery resources in the seas and oceans.

Prenatal infections (PI) remain an actual problem. Taking into account the epidemiological data on the increase in the incidence of syphilis in many countries, a review of modern algorithms for diagnosing this disease in pregnant women and newborns has been carried out. Universal screening for syphilis at the first prenatal examination is recommended by WHO and CDC, and is practiced in most countries. The article also presents the characteristics of modern laboratory methods of serological screening of pregnant women for syphilis and their combinations, one of which is primary screening using the treponemal test “total antibodies to syphilis” with confirmation of a positive result by immunoblotting.Given the controversial nature of approaches to the prevention of other PI and their consequences, this review provides current recommendations for countries that screen and actively manage infections such as cytomegalovirus (CMV) and toxoplasmosis (T). Despite the proven significance of CMV as a factor in PI, universal prenatal screening, similar to screening for syphilis is not practiced in any of the countries due to the absence of prenatal treatment with proven efficacy. According to the national protocol of Germany, serostatus (titers IgG, IgM) to CMV are determined in early pregnancy. Confirmation of congenital CMV infection (HCMVI) is a positive PCR result in the amniotic fluid after 20–21 weeks of gestation. The main method of laboratory diagnostics of HCMVI in a newborn is PCR for CMV in urine. The article also presents the main approaches to the prevention of congenital toxoplasmosis, which have been practiced in France since the 90s and demonstrate effectiveness.Thus, despite the fact that the use of effective prenatal treatment is not possible for all PI, their diagnosis using a complex of modern laboratory and instrumental methods is critical for the child’s health, since it allows the application of an appropriate algorithm for specific treatment and observation from birth

Objective of the study was to evaluate the tolerability and effectiveness of photodynamic therapy (PDT) in patients with vulvar premalignant diseases.Materials and methods. Study was performed in 10 patients on the basis of the National Cancer Institute of Ukraine (Kyiv). Age of patients ranged from 31 to 67 years old (mean age 53.3 ± 3.6 years old). Diagnosis was made on the basis of medical history, complaints and clinical examination of patients, vulvoscopy and results of morphological examination of pathologically altered vulvar tissues. A drug of the chlorine series “Photolon” (RUE “Belmedpreparaty”, Republic of Belarus) in doses from 1 to 2.5 mg/kg was used as a photosensitizer (FS). Photoirradiation of pathologically altered foci was performed 3–4 hours after the end of the FS infusion using a laser coagulator universal “Lika-surgeon” (“Photonics Plus”, Ukraine, λ = 660 nm) with a radiation power of 0.4 W in exposure doses of 100 up to 150 J/cm2. PDT tolerability was assessed basing on the frequency and severity of adverse reactions (CTCAE, version 3.0). PDT effectiveness was assessed basing on the presence/absence of complaints, data from visual observation of changes in the area of treated lesions and morphological examination data at 3 and 6 months after treatment (WHO criteria).Results. No serious adverse reactions associated with FS infusion and PDT session were observed: no allergic reactions (Quincke’s edema, urticaria, drop in blood pressure, bronchospasm), no symptoms of skin phototoxicity. There was remission of clinical symptoms (itch in the area of vulva) in the treated pathological centers and high frequency of clinical and morphological regressions in the control observation terms of patients.Conclusion. Obtained results indicate the relevance and prospects of further researches in the field of laser technology and PDT as options for organ-preserving treatment of vulvar premalignant diseases

Modern mankind, through the development of medicine and using its scientifically grounded innovations has learned to prolong human life. In Ukraine as in the whole world there is a tendency to increase in life expectancy. Since aging is a natural physiological process, a person from time immemorial has been preoccupied with the search for the so-called “Philosophy Stone” is a substance that prevents aging.This article analyzes data from scientific publications on modern aspects of the problems associated with aging of the female body. It has been proven that aging and anti-aging processes substantiate the individualization of modern approaches to the correction of pre- and perimenopause complications. The general strategy for maintaining of women’s health in peri- and postmenopause according to the International Menopause Society includes menopausal hormone therapy, taking into accounts the therapy goals and individual risk factors. Despite all the desire to give a modern definition of aging, it is currently not possible, therefore in this literature review an attempt is made to analyze the known strategies of premature aging to develop the potential for prolonging active life.In any case, the doctor needs to correlate the benefits and risks of menopausal hormone therapy, taking into account individual risk factors and select appropriate rehabilitation methods aimed at “improving the female face” of the classic image of old age. Since the role of estrogen deficiency in the formation of perimenopausal complications and especially premature aging, is not questioned, anti-aging strategies should be considered a pathogenetically justified method of treating vasomotor, psychosomatic symptoms and sleep disorders, as well as a method of preventing metabolic syndrome. It should be remembered that hormone therapy has a number of limitations and contraindications, which is an incentive for every doctor to contribute to prolongation of the active and healthy life of women 40+ and 50+ years old. Creation of a conceptual model for overcoming the complications of reproductive aging and especially cardiovascular events, osteoporosis, cerebrovascular pathology based on the identification of risk factors will allow to develop the protective anti-aging therapy not only to prolong a woman's life, but also to improve its quality

Hyperproliferative diseases of the endometrium play an important role in the structure of gynecological pathology, which are a spectrum of irregular morphological changes. Particularly difficult is evaluation of the phenotypic characteristics of the endometrium hyperplastic processes (EHP) in premenopausal women in the presence of an unstable menstrual cycle. Diagnosis and EHP prognosis remains a difficult task given that it can occur as focal or diffuse lesions with various structural and cytological differences.Objective of the study: to evaluate the immunohistochemical features (phenotypic variants) of benign endometrial hyperplasia in premenopausal women.Material and methods. 33 premenopausal women with abnormal uterine bleeding and verified benign endometrial hyperplasia were examined. Expression of the α-receptors for estrogens type 1 (ER1), progesterone receptors and Ki-67 nuclear protein in the endometrium stroma and glands was analyzed. Micromorphometry was performed and the D-score was calculated.Results. Prevalence of comorbid lesions in patients was the combination of endometrial hyperplasia and fibroids (51.4%), cases of abnormal uterine bleedings against submucosal fibroids (13.5%), endometrial polyps (8.1%), combinations of EHP and peritoneal endometriosis (10.8%), adenomyosis and myoma (8.1%), or other combinations of endometrial and myometrial proliferative pathology. D-score for surgery averaged 1.78 ± 0.11 indicating a low risk of malignancy. There were changes after treatment in the quantitative presentation of the studied proteins in stroma and endometrial glands. Thus, before treatment in the glands was determined up to 100% of cells containing ER1 in large quantities, while after treatment their number decreased by an average of 20%. Similar dynamics was observed with progesterone receptors activity.Conclusions. The main prognostic significant phenotypes of endometrial proliferative pathology have been identified. After removing of pathologically chanced endometrium and subsequent treatment with dydrogesterone during 6 months there is prognostically positive decreasing in the ER1 density as well as the Ki-67 protein expression

Objective of the study: to study the clinical and laboratory efficacy of the Femivag® (contains Lactobacillus gasseri, Lactobacillus rhamnosus) drug in the complex treatment of bacterial vaginosis (BV) in pregnant women with high risk of preterm birth.Materials and methods. 42 pregnant women at the 16–18 weeks of gestation with cervical dysfunction and BV diagnosed before cervical pessary installation were examined and treated. All patients were assessed the dynamics of symptoms severity, performed PCR testі with a quantitative count of opportunistic pathogens and Lactobacillus spp. Perinatal and neonatal outcomes were also assessed. Femivag® vaginal capsules were prescribed to 24 women (main group) to restore the vaginal microbiota after BV treatment. 18 pregnant women used dietary supplements containing pro- and prebiotics (comparison group). The examination was performed before treatment, 4 and 15–16 days from the therapy start, 4 and 8 weeks after treatment.Results. Vaginal probiotic Femivag® as a component of complex therapy of BV before the installation of cerclage pessary was more effective than the oral food supplements with pro- and prebiotics in terms of reducing in vaginal discharge and vaginal discomfort, the disappearance of vaginal itching and burning sensation for 4 days of therapy. Gardnerella vaginalis / Prevotella bivia / Porphyromonas spp., Mobiluncus spp. / Corynebacterium spp. and Atopobium vaginae disappeared and vaginal normobiota significant recovered in the second trimester in women with cervical dysfunction at 4 and 8 weeks from the start of BV treatment with Femivag®. Frequency of premature rupture of membranes and chorioamnionitis significantly decreased in the main group. Femivag® was well tolerated and had no side effects.Conclusions. Femivag® vaginal capsules had a pronounced clinical and laboratory effect in the complex treatment of BV in pregnant women with incompetent cervix

Published: November 2020

Objective of the study: to study changes of electrolyte balance and hematocrit in the first trimester vomiting and in uncomplicated pregnancy.Material and methods. 109 women in the first trimester of pregnancy were divided into 2 groups. Group I consisted of 58 patients with complaints on vomiting from 1 to 10 times a day, group II – 51 women without complaints of nausea and vomiting. At the beginning of the study and at 20 weeks the concentrations of the main electrolytes in the serum, as well as the hematocrit index, were determined in all study participants. Groups were compared basing not only modern concentration level, but also distribution of each meaning in total.Results. Despite the loss of fluid and electrolytes with vomiting, patients in group I did not differ from women with uncomplicated pregnancy in average ion concentrations and hematocrit. However, the distribution of the study participants by the indicators showed that the majority of women in group II had high levels of serum sodium and hematocrit. In addition, the dynamics of pregnancy progression in women of group I showed a decrease in sodium concentration and in pregnant women in group II – on the contrary, the tendency to increase this indicator.Conclusion. Vomiting of the first trimester does not lead to significant changes in electrolyte balance. However, with the progression of pregnancy, such patients show adequate hemodilution, which implies a decrease in sodium concentration and hematocrit. At the same time, in some patients with uncomplicated course of the first trimester of pregnancy, there is a tendency for defective hemodilution. This can lead to endothelial dysfunction and associated obstetric complications, by the time patients with first pregnancy vomiting have more favorable changes of blood circulation

Objective: to study the hemostatic efficacy of compression of the lower uterine segment (COLUS) as a new method to stopping bleeding during cesarean section on the background of placenta previa.Materials and methods. The main group included 30 women with placenta previa, who were routinely delivered by cesarean section and using the COLUS technique after separation and isolation of placenta during a gestation period of 36 weeks – 36 weeks + 6 days. The control group consisted of 31 pregnant women with placenta previa, who had a planned delivery by сesarean section using the classical technique of suturing the uterus at a gestational age of 38–39 weeks. After separation and isolation of the placenta placental bleeding was stopped by flashing and coagulation of bleeding vessels in lower uterine segment.Results. In the control group after standard caesarean section technique a high percentage of blood loss from 1000 ml or more was observed, that is typical for operations performed with placenta previa. In the main group a significantly smaller number of cases of blood loss from 1000 ml or more were observed. The average volume of blood loss in the control group was 1277 ± 119 ml, and 697 ± 139 ml in the main group, that is indicates the high efficiency of the COLUS technique. This technique allows to reduce blood loss by 45% of the blood loss of the control group. There was no significant difference in the condition of the newborns in both groups.Conclusions. The data obtained indicate the advisability of delivery of pregnant women with placenta previa in the gestation period of 36 weeks – 36 weeks + 6 days. Performing a cesarean section in the absence of a developed lower uterine segment in combination with the COLUS technique is an effective and safe surgical method for prevention of blood loss in a complex of therapeutic measures to prevent massive obstetric bleeding. It is an addition to surgical means to stop bleeding from the lower uterine segment after separation and removal of the underlying placenta

The article presents the results of microtomographic and petrographic investigations of Rotliegend sandstones collected from core material from wells located in the area of the Fore-Sudetic Monocline in its central and northern parts and also on the border of the Fore-Sudetic Monocline and the Mogilno - Łódź Synclinorium. Three areas were selected for the study: Czarna Wieś–Parzęczewo (19 samples), Środa Wielkopolska–Kromolice (21 samples) and Siekierki–Miłosław (21 samples). The aim of the petrologic and microtomographic studies was to investigate how the different reservoir properties of sandstones will be reflected in the results of the methods used. Strong differences between samples from the region of Środa Wielkopolska–Kromolice and the other studied areas have been demonstrated. In the case of this area several key factors were noticed: the highest average value of effective porosity; the highest average content of pores belonging to class VII (pore volume subsystem classification); three times higher average value of the CT porosity coefficient and the largest length of the average chord. Also in terms of petrography (composition of grains, cement type) it is a region where major differences, especially compared to the region of Czarna Wieś–Parzęczewo, can be seen. Based on the obtained results, it was possible to rank the examined regions in terms of their reservoir properties – from the worst (Czarna Wieś–Parzęczewo) to the best (Środa Wielkopolska–Kromolice). These conclusions are also confirmed by other petrophysical analyses (eg. mercury porosimetry, permeability analysis). Combination of the obtained microtomographic and petrographic results allowed to obtain a full characterization of the investigated samples – both in terms of the mineralogical composition of grains, as well as the development of the pore space. These data, especially in combination with the results of density and porosity analyses (helium pycnometry and mercury porosimetry), open up a number of possibilities to carry out different types of modeling (porosity, permeability) both on the scale of the sample itself, as well as the scale of a single well or even the whole basin, which is crucial for creating a hydrocarbon exploration strategy.

Chemicals are added to crude oil to ensure that it flows from the well to the processing plant. Depending on the composition of the reservoir fluids being extracted (crude oil, reservoir water, natural gas), paraffin may be separated from the crude oil, hydrates may be formed from reservoir water and natural gas, and the combination of reservoir water and crude oil may form an emulsion. Those situations should be avoided to ensure continuous flow from the wellbore to the processing plant. To this end, chemicals, paraffin inhibitors, hydrate inhibitors, and demulsifiers are used. Based on the literature on the subject and on the author’s own experience from observing technological processes, research methods were proposed to assess the effectiveness of chemicals used to ensure the continuity of crude oil flow. The crude oil selected for the tests was characterised by a high content of paraffins, asphaltenes, chloride ions, and water. To determine the onset of paraffin precipitation, tests were conducted based on a change in viscosity and a coupon method – determining the weight gain on a coupon to check the effectiveness of a paraffin inhibitor. The rate of emulsion separation was evaluated in separating funnels. The water released from crude oil often leaches the salt contained within it. Various demulsifiers were used to investigate the separation of emulsions and the purification of oil from salts; silicone demulsifiers in particular were considered. To determine the change in the amount of salt in crude oil, a conductometric measurement was performed. The amount of demulsifier used for phase separation was determined by changing the surface tension. The proposed solution for the use of chemicals to transport and purify crude oil yields tangible economic benefits. The article summarises the research procedures and presents the results for selected crude oil and chemicals.

Corrosion of metals is the gradual destruction of metal under the impact of environmental factors. Chemical or electrochemical processes on the surface of the metal cause irreversible changes in the structure of the metal. To prevent this, during storage or transport, the surfaces of metal elements must be protected against environmental factors, which include: high air humidity, acid rain and variable temperature. These factors accelerate the corrosion process, which cannot be eliminated, but can be reduced by protecting metal elements with e.g. protective oils. Some metals have the ability to passivate, which is a natural protective agent that prevents corrosion. It consists in the formation of an oxide of this metal on the metal surface. Where there is no natural protection against corrosion, protective measures must be used. This paper presents the technology for the production of protective oil for temporary protection against corrosion. The innovation of this project is that the oil will form a thin, well adhering protective layer on the metal surface, which can be easily removed. It is characterised by very low viscosity and low dripping time. It is possible to achieve by using proper base oil with carefully selected anti-corrosion additives. Based on the standard PN-75/C-04154 Petroleum products. Rust protection by metal preservatives the humidity cabinet test method, corrosion tests were carried out. The paper presents the results of a humidity cabinet test for an oil mixture based on deeply refined base oil and properly selected refining additives. The test results confirmed very good anti-corrosive properties of the developed oil due to the use of a corrosion inhibitor and an oxidation inhibitor. The thickness of the protective layer formed on the metal surface was calculated based on a mathematical formula. The resulting layer forms a thin oil film, easy to remove and protecting the metal surface from corrosion.

Embora uma das mais importantes matrizes culturais brasileiras, a matriz africana é muitas vezes relegada à segundo plano, sobretudo na história do teatro, onde aparece marginalmente. Justamente por isso, escolhemos discutir aqui relações possíveis entre figurino, ancestralidade e memória, a partir do espetáculo Oxum (2018), do NATA, escolhido pelo caráter extremamente simbólico de seu figurino, que transita liminarmente entre o ritual e o teatral.

Published: November 2020

Nesse artigo eu analiso a relação entre discurso e violência no teatro negro a partir do espetáculo A roda do mundo, da Cia dos Comuns. Eu argumento que ao reivindicar a palavra, a Cia dos Comuns confronta um dos principais aspectos relacionados à persistente objetificação e desumanização do corpo negro: a negação do reconhecimento do corpo negro como um corpo capaz de ter e exercer uma perspectiva própria sobre si mesmo e sobre o mundo.
