Dewerbalne osobowe nomina subiecti z formantem słowotwórczym -нік (-льнік) w języku białoruskim
Authors: Goral Agnieszka 
Published: May 2019

<p>Artykuł został poświęcony analizie semantycznej i słowotwórczej dewerbalnych rzeczowników rodzaju męskiego należących do kategorii <em>nomina subiecti</em> z formantem słowotwórczym <em>-</em><em>нік</em> (<em>-</em><em>льнік</em>) w języku białoruskim w ujęciu synchronicznym. Pod pojęciem<em> nomina subiecti</em> rozumiane są nazwy osób, wykonujących jakąś pracę lub podejmujących jakieś zajęcie, przy tym praca ta może mieć charakter stały bądź tymczasowy, zarobkowy lub nie związany z korzyściami materialnymi. Analizowane nazwy, których znaczenie słowotwórcze można ująć w peryfrazie ‘ten, kto wykonuje czynność związaną z czasownikiem będącym podstawą słowotwórczą’, stanowią zbiór 228 białoruskich derywatów osobowych, zaczerpniętych z białoruskich i polskich słowników, prac leksykograficznych z zakresu słowotwórstwa synchronicznego nazw osobowych oraz materiałów własnych autora. Z punktu widzenia semantyki badana kategoria derywatów reprezentuje słownictwo należące do sfery życia codziennego, obejmujące zarówno nazwy zawodowe, jak i nazwy subiektów czynności tymczasowych i okazjonalnych, przy tym są to nazwy zakorzenione w systemie słowotwórczym języka białoruskiego, oznaczające nazwy wykonawców czynności rolniczych, przemysłowych, rzemieślniczych. Przeprowadzona analiza dowiodła, że w języku białoruskim grupa osobowych dewerbalnych <em>nomina</em><em> </em><em>subiecti</em> z sufiksem <em>-</em><em>нік</em><em> </em>(<em>-льнік</em>) stanowi zbiór liczny, jednak na obecnym etapie rozwoju języka formant <em>-нік</em> (<em>-</em><em>льнік</em>) praktycznie nie tworzy nazw zawodowych. Stosunkowo niewielki zbiór neologizmów dowodzi, że w przegrywa on w rywalizacji z innymi sufiksami, zwłaszcza obcymi (por. <em>-</em><em>ант</em>, <em>-</em><em>іст</em>), a dotyczy to przede wszystkim sfery polityki, kultury masowej, sportu. Z kolei ze względu na budowę badany sufiks wykazuje łączliwość z rodzimymi podstawami słowotwórczymi, a proces derywacji cechuje znaczny stopień regularności.</p>

Case:
We report on a patient with heterozygous prothrombin G20210A mutation (PTM) and a history of venous thromboembolism (VTE) after knee arthroscopy, who was undergoing hip arthroscopy. This common mutation has an overall prevalence of 2.0% and results in a 280% to 420% likelihood of thrombosis compared to patients without the mutation.

Conclusions:
Hip arthroscopy is associated with a low risk of VTE with currently no guidelines for thromboprophylaxis. Patients should be managed in relation to their risk factors utilizing a collaborative, individualized approach. Treatment with short-term low-molecular-weight heparin resulted in no thromboembolism at 18-month follow-up for this patient with PTM.

Abstract
Background

Two outbreaks of acute conjunctivitis occurred successively with an interval of five days in two boarding primary schools in Weixi Lisu autonomous county, Diqing Tibetan autonomous prefecture, Yunnan. The aims of this study were to determine the intensity of and characteristics of outbreaks, as well as the clinical manifestation of patients and risk factors infected, and the pathogen causing two outbreaks.

Methods

An outbreak investigation and a case-control study were conducted in two primary schools. The relevant specimens were collected by case definition, Next generation sequencing was adopted to identify the pathogen, and the epidemiological investigation method was used to analyze the related epidemiological characteristics such as risk factors. The phylogenetic tree was constructed by MEGA 7.0.

Results

A total of 331 acute conjunctivitis cases, as acute hemorrhagic conjunctivitis probable cases, were reported in two schools and the attack rates were 30.59% (171/559, 95%CI: 26.76-34.42) and 20.41% (160/784, 95%CI: 17.58-23.24), respectively. Cases occurred in all grades and classes in both schools, and only one staff was ill in each school. Epidemic situations lasted for 54 days and 45 days, respectively. Epidemic curve of two breaks appearing two peaks indicated the mode of person-to-person transmission for two outbreaks. The patients had typical manifestations of epidemic keratoconjunctivitis (EKC) such as acute onset, follicular hyperplasia, pseudomembrane formation, preauricular lymphadenopathy, corneal involvement and blurred vision, and the longer course of the disease (average 9.40 days, longest 23 days and shortest 7 days). The risk factor in infection was close contact with the patient or personal items contaminated by the patient. The pathogen caused the outbreaks is HAdV-8. The virus was highly homologous to the 2016 HAdV-8 strain in Tibet, China.

Conclusions

This study strongly suggests that HAdV-8 could lead to serious consequences. This is the second report of a HAdV-8 associated EKC outbreak in mainland of China. Tibetan HAdV-8 might be circulating in southwest China, it is necessary to monitor the pathogen of acute conjunctivitis in this area.

Abstract
Background

Escherichia coli lineage ST131 predominates across various spectra of extra-intestinal infections, including urinary tract infection (UTI). The distinctive resistance profile, diverse armamentarium of virulence factors and rapid global dissemination of ST131 E. coli makes it an intriguing pathogen. However, not much is known about the prevalence and genetic attributes of ST131 lineage in Pakistan.

Methods

We estimated the prevalence and genetic attributes of E. coli ST131 isolates causing UTI among 155 randomly selected samples. Samples were analyzed by phylogenetic grouping, O-typing, fumC/fimH typing. Isolates were further tested for ESBL and virulence factors using PCR.

Results

Overall, 59% of the UPEC isolates belonged to the phylogenetic group B2, followed by D=28%, B1= 8% and A= 5%. Among 18 different Sequence-types, ST131 was the dominant lineage (n=71; 46%) out of which 72% of the isolates were assigned to phylogenetic group B2 while 61% adhered to serogroup O25b. FumC/fimH typing confirmed 49% of the ST131 as H30 sub-types. In this study, significant numbers of the identified ST131 isolates were MDR and 42% showed ESBL phenotypes, out of which 57% carried blaCTX-M-15. Moreover, different virulence factors were detected in following percentages: fimH,155 (100%), iutA 86 (55%), feoB 76 (49%), papC 75 (48%), papGII 70 (45%), kpsMTII 40 (26%), papEF 37 (24%), fyuA 37 (24%), usp 22 (14%), papA 20 (13%), sfa/foc 20 (13%), hlyA 18 (12%), afa 15 (10%), cdtB 11 (7%), papGI 6 (4%), papGIII 6 (4%), kpsMTIII 4 (3%) and bmaE2 (1%).

Conclusion

Conclusively, this study provides important insights into the genetic and virulence attributes of pandemic MDR ST131 strains involved in UTIs. It also highlights high prevalence of ST131-O25b-H30 UPEC isolates in local population, which was previously unreported from this part of globe. Keywords: ST131, VF genes, ESBL, UPEC, MDR

Abstract
Background

The infusion of magnesium sulfate is well known to reduce arterial pressure and attenuate hemodynamic response to pneumoperitoneum. This study aimed to investigate whether different doses of magnesium sulfate can effectively attenuate the pneumoperitoneum-related hemodynamic changes and the release of vasopressin in patients undergoing laparoscopic gastrointestinal surgery.

Methods

Sixty-nine patients undergoing laparoscopic partial gastrectomy were randomized into three groups: group L received magnesium sulfate 30 mg/kg loading dose and 15 mg/kg/h continuous maintenance infusion for 1 h; group H received magnesium sulfate 50 mg/kg followed by 30 mg/kg/h for 1 h; and group S (control group) received same volume 0.9% saline infusion, immediately before the induction of pneumoperitoneum. Systemic vascular resistance (SVR), cardiac output (CO), mean arterial pressure (MAP), heart rate (HR), serum vasopressin and magnesium concentrations were measured. The extubation time, visual analogue scale were also assessed. The primary outcome is the difference in SVR between different groups. The secondary outcome is the differences of other indicators between groups, such as CO, MAP, HR, vasopressin and postoperative pain score.

Results

Pneumoperitoneum instantly resulted in a significant reduction of cardiac output and an increase in mean arterial pressure, systemic vascular resistance, and heart rate in the control group (P < 0.01). The mean arterial pressure (T2 – T4), systemic vascular resistance (T2 – T3) and the level of serum vasopressin were significantly lower (P < 0.05) and the cardiac output (T2 – T3) was significantly higher (P < 0.05) in group H than those in the control group. The mean arterial pressure (T4) and systemic vascular resistance (T2) were significantly lower in group H than those in group L (P < 0.05). Furthermore, the visual analogue scales at 5 min and 20 min, the level of vasopressin, and the dosage of remifentanil were significantly decreased in group H compared to the control group and group L (P < 0.01).

Conclusion

Magnesium sulfate could safely and effectively attenuate the pneumoperitoneum-related hemodynamic instability during gastrointestinal laparoscopy and improve postoperative pain at serum magnesium concentrations above 2 mmol/L.

Abstract
Treated wastewater is commonly used for park irrigation in arid zones of Mexico without considering groundwater contamination. The objective was to investigate the possibility of nitrogen compounds leaching into the groundwater and their subsequent reactions in the main types of soils. Lysimeters samples were taken to scrutinize the soil characteristics of the green areas irrigated with treated wastewater from the Northern Wastewater Treatment Plant in the city of Chihuahua. Testing samples were setup to recreate treated wastewater irrigation conditions. Nitrogen-based compounds were identified and measured before and after percolation through the soil columns. Based on the results, one meter of sand column was sufficient to remove 68 to 100% of nitrogen compounds present in the residual water. The removal of all nitrogen-based compounds as they percolate through one meter of clay soil column was not enough, due to the biochemical reactions that occur through the percolation process. Results indicate minimal risk of nitrate and nitrite leach into the aquifer, since the average static level depth is 20 m which provide broad filtration. This demonstrates an opportunity for in-situ investigations to reevaluate the standards for soil aquifer treatment recharge, based on the soil type and water quality of the area.
Influence of Various Modes of Delivery on Mother-infant Bonding: A Prospective Observational Study
Authors: Poojari Vidyashree Ganesh , Vasudeva Akhila , Sudha Vidya 
Published: May 2019

Background:
Mother-infant bonding has tremendous implications for the child's future
development. The difficulties that some mothers have in establishing an emotional bond with their
newborns often referred to as impaired bonding or bonding failure are an essential focus in the
postpartum period. Therefore, it is important to identify predictive factors for bonding failure and to
intervene at an early stage for the better mental health care of mothers as well as infant.

Objective:
To determine the effect of various modes of delivery on the mother-infant bonding.

Methods:
Prospective observational study performed on low-risk singleton pregnancy who delivered
at term. Mother-to-Infant Bonding Scale (MIBS; Taylor et al., 2005), a validated self-report test
was used to measure mother's feelings towards her baby within three days of delivery and at the end
of six weeks postpartum period. Total score ranges from 0 to 24. A total MIBS score of ≥ 2 is established
as cut-off indicating “poor bonding”. MIBS score of 0 and 1 is considered as “good bonding”.
The mean bonding score among the 3 groups was compared.

Results:
Elective cesarean delivery group had 112 participants, 115 were Emergency cesarean
group and 107 were vaginal delivery group. Immediately after the delivery (MIBS 1), the proportion
of women with poor bonding among Emergency cesarean group was 34.8% when compared to
proportion of women with poor bonding among Elective cesarean (11.6%) and Vaginal delivery
(13%). This was statistically significant (p-value 0.01). When we followed up these mothers at 6
weeks post-partum checkup, the MIBS scoring (MIBS-2) consistently improved among the three
groups. However, proportion of women with poor bonding still remained high at 16.5% among the
Emergency cesarean group.

Conclusion:
Mode of delivery has a significant impact on MIBS. In this study, unplanned cesarean
delivery was associated with a high incidence of poor mother to infant bonding. Poor bonding was
commoner in this group even at 6 weeks post-partum, compared to those undergoing a successful
vaginal delivery and a planned elective cesarean delivery.
Preliminary Studies on Non-Reactive Flow Vortex Cooling
Authors: Rajesh T.N. , Jothi T.J.S. , Jayachandran T. 
Published: May 2019

Background:
The impulse for the propulsion of a rocket engine is obtained from the combustion
of propellant mixture inside the combustion chamber and as the plume exhausts through a convergent-
divergent nozzle. At stoichiometric ratio, the temperature inside the combustion chamber can
be as high as 3500K. Thus, effective cooling of the thrust chamber becomes an essential criterion while
designing a rocket engine.

Objective:
A new cooling method of thrust chambers was introduced by Chiaverni, which is termed as
Vortex Combustion Cold-Wall Chamber (VCCW). The patent works on cyclone separators and confined
vortex flow mechanism for providing high propellant mixing with improved degree of turbulence
inside the combustion chamber, providing the required notion for studies on VCCW. The flow inside a
VCCW has a complex structure characterised by axial pressure losses, swirl velocities, centrifugal
force, flow reversal and strong turbulence. In order to study the flow phenomenon, both the experimental
and numerical investigations are carried out.

Methods:
In this study, non-reactive flow analysis was conducted with real propellants like gaseous
oxygen and hydrogen. The test was conducted to analyse the influence of mixture ratio and injection
pressure of the propellants on the chamber pressure in a vortex combustion chamber. A vortex combustor
was designed in which the oxidiser injected tangentially at the aft end near the nozzle spiraled up to
the top plate and formed an inner core inside the chamber. The fuel was injected radially from injectors
provided near the top plate and the propellants were mixed in the inner core. This resulted in enhanced
mixing and increased residence time for the fuel. More information on the flow behaviour has been
obtained by numerical analysis in Fluent. The test also investigated the sensitivity of the tangential
injection pressure on the chamber pressure development.

Results:
All the test cases showed an increase in chamber pressure with the mixture ratio and injection
pressure of the propellants. The maximum chamber pressure was found to be 3.8 bar at PC1 and 2.7 bar
at PC2 when oxidiser to fuel ratio was 6.87. There was a reduction in chamber pressure of 1.1 bar and
0.7 bar at PC1 and PC2, respectively, in both the cases when hydrogen was injected. A small variation in
the pressure of the propellant injected tangentially made a pronounced effect on the chamber pressure
and hence vortex combustion chamber was found to be very sensitive to the tangential injection pressure.

Conclusion:
VCCW mechanism has been to be found to be very effective for keeping the chamber
surface within the permissible limit and also reducing the payload of the space vehicle.

Published: May 2019

Objectives.The article describes an electronic model of the soil to study its rheological properties and study the process of cutting passive working bodies (knives) of mineral soils with trench-less method of building a closed drainage.Method.The essence of the method consists in cutting through the ground with the help of a passive working body of a narrow slit under a given slope and simultaneously laying a drainage (usually plastic) pipe with a filter on its bottom.Result.The trenchless method is characterized by the possibility of laying pipes at high speeds, the simplicity of the design of drainage machines and, most importantly, the possibility of building drainage in water-saturated and collapsing mineral soils. A big advantage is the possibility of using a drainage machine with a trenchless method in conditions of small slopes with a sufficient length of stacked drains.Conclusion.The study of the process of cutting mineral soils with narrow, deep knives on an electronic model makes it possible, at the design stage, to evaluate the effect of changes in various factors and parameters on the operating modes of the drainage machine; if necessary, make changes to the complex of works on the construction of drainage using the trenchless method with the help of the BDM-300 bed-draining machine, as well as to determine the composition and duration of the work operations of the trench-free bed-draining machine.

Objectives. The aim of this work is to study the theoretical aspects and technological possibilities of chemical activation and modification of organic clay raw materials of the Volga region in organic additives to obtain composite building materials based on previous work on the development of clay cement composites.Method. In connection with the high physicochemical activity of clay and cement with respect to organic additives and mineral salts, expressed in the high adsorption activity and sensitivity of hydration processes, studies of the structure of clay were studied separately from cement. To determine the change in pH value of suspensions from clay and clay cement raw materials, the role of the influence of ECA products of treatment of aqueous-salt solutions of sodium chloride and ACF resin was studied.Result. The results of the tests showed that by changing the pH values of the clay cement samples by the products of electrochemical activation of water-salt solutions, it is possible to actively influence the active centers of the surface of clay particles. The adsorption and capacity of the cation exchange of clay raw materials are reduced when they are modified with acetone formaldehyde resin.Conclusion. The studies carried out to study the structure formation and the nature of the effect of the pH of the system environment on the process of the condensation of the ACF resin create the prerequisites for further research in the field of soil consolidation, their stabilization and enhance-ment of operational parameters.

Published: May 2019

Objectives. Study of the problems associated with the possibility of the effective use of substandard sand dunes of the Shelkovskoye deposit as a mineral additive for the production of fine-ground binders and the enrichment of rock crushing screenings.Method. They are based on the established principles of the theory of hardening repair modified compositions with the integrated use of vibroactivated mineral and polymer components, and in particular, the filled system “Portland cement - sandstone - C-3”, as well as mathematical logic and technology of composite materials. The studies were carried out taking into account current state standards and recommendations.Result. The results of the study of local sand dunes and rock crushing screenings are presented for obtaining enriched aggregates with optimal granulometry and properties. Repair compositions were obtained with the use of polymineral sand sand, which are part of the activated binder as a filler, and which are one of the main components of the enriched aggregate.Conclusion. The optimal formulation of enriched sand was established, with removal of 60% of the fraction 2.5 - 1.25 mm from the crushing screenings and the addition of 40% of the fraction of 0.315 - 0.14 mm of sand sand, which significantly reduces the void content of the aggregate to 38.8% and the water requirement of the aggregate to 6.5%, significantly improving the properties of the repair compositions obtained with their use. It has been proved that the studied sand dunes with a characteristic mineralogical, chemical and particle size distribution are an effective component.
