Authors: Eliso Maria Concetta , Corsi Ilaria , Manfra Loredana , Spagnuolo Antonietta
Published: May 2022

Within EU approval policies, most dispersant ecotoxicity testing considers lethal concentrations for marine adult species, overlooking the embryotoxicological effects. Here we studied the ecotoxicity of two commercial dispersant formulations (dispersant A and B) on the embryogenesis of the ascidian Ciona robusta. Embryotoxicity and phenotypic alterations stated that dispersant B resulted more toxic than A (EC50 value of 44.30 and 160 μg mL−1, respectively) and induced severe larvae malformations at lower concentrations. Furthermore, the analysis of genes involved in different cellular response pathways indicated that those belonging to biotransformation were upregulated by dispersant A treatment, likely related to the presence of hydrocarbons. Instead, dispersant B induced cas8 gene downregulation, probably as a result of the prolonged exposure to mixture components. Our preliminary findings support the use of the C. robusta embryotoxicity test as a valuable tool for dispersant approval procedures, by providing sub-lethal responses on marine invertebrates closely related to vertebrates.

Published: May 2022

With the increasingly prominent ecological environmental problems, the ecological drought phenomenon will become the focus of drought research. The spatial–temporal pattern of ecological drought and its complicated propagation dynamics are still unclear in the North China Plain (NCP). In this study, the spatio–temporal patterns and gridded trend characteristics of ecological drought were investigated from 1999 to 2019 in the NCP. Subsequently, the propagation dynamics from meteorological to ecological drought were identified for the study period. The results indicated that: (1) the ecological drought showed a downward trend from 1999 to 2019 in the NCP, with a 4.2-year and 7-year period on the inter-annual scale; (2) the most serious ecological drought occurred in the year of 2002, with an average monthly vegetation condition index (VCI) ranging from 0.17 (in December) to 0.59 (in January); (3) ecological droughts were decreasing in each month and season at the grid scale; (4) the propagation time from meteorological to ecological drought was 2.67 months in winter and 1.33 months in summer, which is helpful for predicting the occurrence of ecological drought. This study sheds new viewpoints into the spatial–temporal patterns and propagation dynamics of ecological drought in the NCP, which can also be applied in Northeast China.

Published: May 2022

In a reservoir area, impulsive landslide surges induced by slope failure may pose huge damage to the dam and the lives in the shoreline areas, which are greatly affected by river channel characteristics. In this study, water depth, the width of the water surface, and the bending angle of river channel were chosen as the main influencing factors. The numerical method was used to investigate the influence of river channel characteristics on wave propagation and the distribution of dynamic water pressure on the dam surface. The effect mechanism was analyzed, and a prediction model considering river channel characteristics for the propagation wave height was established. Results show that water depth and the bending angle of the river channel play a positive role in the attenuation of the energy carried by landslide surges. The width of the water level mainly influences the propagation of impulse waves in the far-field area. The river channel characteristics affect the value of the dynamic pressure on the dam surface but have a minor effect on dynamic pressure distribution. The distribution of dynamic pressure on the dam is greatly influenced by the distance between the dam site and the place where the landslide occurs.

Water quality is mainly assessed using traditional water quality assessment methods that measure chemical parameters against established standards. The water quality index is used worldwide for water quality assessment. The main parameters evaluated include the total dissolved solids, electrical conductivity, nitrite, and nitrate. In this study, the WQI combined with microbiological analyses was used to assess the water quality of two rivers, Munim and Iguará. Data obtained in this study were then correlated using multivariate statistical analysis. Principal component analysis grouped the monitored sampling points into three clusters and identified temperature, Escherichia coli, and turbidity, as features correlated to the rainy season, while phosphorus, total dissolved solids, and biochemical oxygen demand are associated with the dry season. Four principal components explained 81.20% of the data variance during the studied seasons. The evaluated correlations indicated that in the rainy season, E. coli (~443.63 CFU/100 mL) and turbidity (~36.51 NTU) levels were the highest. However, in the dry season, the levels of phosphorus (~4.25 mg·L−1), total dissolved solids (145.46 mg·L−1), and dissolved oxygen (~9.89 mg·L−1) were the highest.

Published: May 2022

Cultivation of photosynthetic microorganisms in wastewater is a potential cost-effective method of treating wastewater and simultaneously providing the essential nutrients for high-value biomass production. This study investigates the cultivation of the cyanobacterium Arthrospira platensis in non-diluted and non-pretreated brewery wastewater under non-sterile and alkaline growth conditions. The system’s performance in terms of biomass productivity, pollutant consumption, pigment production and biomass composition was evaluated under different media formulations (i.e., addition of sodium chloride and/or bicarbonate) and different irradiation conditions (i.e., continuous illumination and 16:8 light:dark photoperiod). It was observed that the combination of sodium bicarbonate with sodium chloride resulted in maximum pigment production recorded at the end of the experiments, and the use of the photoperiod led to increased pollutant removal (up to 90% of initial concentrations) and biomass concentration (950 mg/L). The composition of the microbial communities established during the experiments was also determined. It was observed that heterotrophic bacteria dominated by the phyla of Pseudomonadota, Bacillota, and Bacteroidota prevailed, while the cyanobacteria population showcased a dynamic behavior throughout the experiments, as it increased towards the end of cultivation (relative abundance of 10% and 30% under continuous illumination and photoperiod application, respectively). Overall, Arthrospira platensis-based cultivation proved to be an effective method of brewery wastewater treatment, although the large numbers of heterotrophic bacteria limit the usage of the produced biomass to applications such as biofuel and biofertilizer production.

Published: May 2022

Dam and reservoir systems (DRSs) are crucial aspects of the infrastructure necessary for reliable water resource management. Nowadays, DRSs are being increasingly affected by numerous natural and anthropogenic impacts (aging and outdated infrastructure, climate change, natural hazards, global crises, etc.). Hence, additional pressure on DRS management is being applied as DRSs must be operated in adverse operating conditions, outside of their design envelopes. Since there is no practical way to redesign DRSs to meet all possible adverse conditions, efficient simulation tools are necessary for various “what-if” analyses. A system dynamics (SD) approach can be used, as it has shown the capacity to comprehend the intrinsic system complexity. In this paper, an 11-step framework for the dynamic modelling of reduced functionality in a DRS and the emulation of the system operation in adverse conditions is proposed. The framework covers the system model design, input scenario generation, system simulation, and performance evaluation steps. A focus is placed on the steps related to system decomposition, the identification of failure-indicative parameters, the definition and implementation of failure functions in the subsystem dynamic models, and dynamic failure modelling. Through these steps, a novel procedure is proposed for the dynamic modelling of the DRS subsystems’ failures (reduced functionality), common in the operation of DRSs under adverse conditions. For each subsystem prone to failure, failure-indicative parameters are identified. Failure functions employing generic functionality indicators, with values spanning from 0 to 1, are suggested to modify the values of the failure-indicative parameters in simulations and emulate the component failure impacts on DRS operation. Possibilities for modelling failure modes for different subsystems, varying in nature, duration, and magnitude are discussed. Potential physical damage to the system components, increases in measurement uncertainty, and the lack of the spare parts during periods of global crisis are applied as disturbances to the Pirot DRS case study to illustrate the possibilities of the suggested framework’s application for DRS failure modelling. It was concluded that the proposed framework allowed for the detection of severe impacts on system performance, emphasizing the need for DRS dynamic failure modelling in system analysis.
A Review of the Techno-Economic Feasibility of Nanoparticle Application for Wastewater Treatment
Authors: Mpongwana Ncumisa , Rathilal Sudesh
Published: May 2022

The increase in heavy metal contamination has led to an increase in studies investigating alternative sustainable ways to treat heavy metals. Nanotechnology has been shown to be an environmentally friendly technology for treating heavy metals and other contaminants from contaminated water. However, this technology is not widely used in wastewater treatment plants (WWTPs) due to high operational costs. The increasing interest in reducing costs by applying nanotechnology in wastewater treatment has resulted in an increase in studies investigating sustainable ways of producing nanoparticles. Certain researchers have suggested that sustainable and cheap raw materials must be used for the production of cheaper nanoparticles. This has led to an increase in studies investigating the production of nanoparticles from plant materials. Additionally, production of nanoparticles through biological methods has also been recognized as a promising, cost-effective method of producing nanoparticles. Some studies have shown that the recycling of nanoparticles can potentially reduce the costs of using freshly produced nanoparticles. This review evaluates the economic impact of these new developments on nanotechnology in wastewater treatment. An in-depth market assessment of nanoparticle application and the economic feasibility of nanoparticle applications in WWTPs is presented. Moreover, the challenges and opportunities of using nanoparticles for heavy metal removal are also discussed.

Due to its recalcitrant and carcinogenic nature, the presence of methyl orange (MO) in the environment is a serious threat to human and animal life and is also toxic to plants. MO being recalcitrant cannot be effectively reclaimed from industrial effluents through physical and chemical approaches. Biological methods on the other hand have the potential to degrade such dyes because of their compatibility with nature and low chances of adverse effects on the environment. Bacteria, due to their fast growth rate and capability of surviving in extreme environments can effectively be used for this purpose. In the current research study, Pseudomonas aeruginosa was isolated and characterized using 16rRNA from textile wastewater. In the preliminary tests it was found that Pseudomonas aeruginosa has the ability to degrade and mineralize methyl orange effectively. The physicochemical conditions were then optimized, in order to get maximum degradation of MO which was achieved at 37 °C, a pH of 7, a low salt concentration of 0.1 g/15 mL, a high carbon source of 0.6 g/15 mL, and 72 h experimental time. In a single set of experiments where all these optimum conditions were combined, 88.23% decolorization of the selected dye was achieved. At the end of the experimental cycle, the aliquots were homogenized and filtered. The filtrates were subjected to FTIR and GC-MS analysis where azo linkage breaking was confirmed from the FTIR spectra. The filtrates were then extracted with ethyl acetate and then passed through a silica gel column. On the basis of Rf value (TLC plates used) similar fraction were combined which were then subjected to NMR analysis. The compounds detected through GC-MS, peaks were not observed in proton and C-13 NMR. Instead, solvent and some impurity peaks were present, showing that complete mineralization of the dye had occurred due to the action of different bacterial enzymes such as azoreductase, peroxidases, and classes on MO. The prosed mechanism of complete mineralization is based on spectral data that needs to be verified by trapping the individual step products through the use of appropriate inhibitors of individual enzymes.
Simulated Changes in Seasonal and Low Flows with Climate Change for Irish Catchments
Authors: Meresa Hadush , Donegan Seán , Golian Saeed , Murphy Conor
Published: May 2022

We assess changes in the seasonal mean and annual low flows (Q95) for 37 catchments across the Republic of Ireland. Two hydrological models (SMART and GR4J) are trained and evaluated for their ability to capture key hydrological signatures from observations before being forced with bias corrected outputs from 12 Earth System Models from the CMIP6 ensemble. Projected changes are derived for three shared socio-economic pathways (SSP126, SSP370 and SSP585) for the 2020s, 2050s, and 2080s. The results show a wide range of change in all metrics across the catchment sample. While even the direction of change is highly uncertain in spring and autumn, there is a tendency towards increased flows in winter and reduced flows in summer, together with large reductions in annual low flows. Under SSP370, the median reduction in summer flows across catchments for the 2080s simulated by GR4J is −21.3 percent (90 percent CI: 4.8 to −36.9 percent). For Q95, for the 2080s, GR4J returns a median reduction of −20.9 percent (90 percent CI: −2.5 to −38.2 percent), while SMART suggests a median reduction of −21.2 percent (90 percent CI: −6.0 to −36.9 percent). Such changes would pose significant challenges for water management, requiring significant adaptation. Notably, for low flows in particular, significant reductions in emissions under SSP126 result in more moderate future changes, indicating the importance of both adaptation and mitigation to sustainable water management.

Published: May 2022

The biophysical modeling of water ecosystem services is crucial to understanding their availability, vulnerabilities, and fluxes. Among the most popular models, the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) models stand out. While many studies have used them, few have assessed their performance. This study evaluates the performance of InVEST’s Seasonal Water Yield, Nutrient Delivery Ratio, and Sediment Delivery Ratio models in a subtropical basin in southeastern Brazil on temporal and spatial scales, using 39 years of streamflow data, 29 for total phosphorus and total nitrogen, and 19 for total suspended solids. Statistical indicators R2, PBIAS, and NSE, were also calculated. The performance of the models varied according to the type of simulated WES and analysis scales used, with the Seasonal Water Yield model demonstrating the best performance and effectively representing the spatial and temporal variability of the average annual streamflow. All models performed well in simulating long-term mean values when compared to observed data. While one should bear in mind the study’s limitations, the results indicate that the models perform well in terms of relative magnitude, although their application in studies involving water-resource management and decision making is limited.

Published: May 2022

Pharmaceuticals and personal care products (PPCPs) were investigated in five wastewater treatment plants (WWTPs), groundwater, irrigated soils, and plants in Amman and Al-Balqa governorates in Jordan. PPCPs were extracted from water samples by solid-phase extraction (SPE) and analyzed by high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC–MS/MS). Carbamazepine, ciprofloxacin, ceftiofur, diclofenac, erythromycin, lincomycin, ofloxacin, pyrimthamine, spiramycin, sulfamethoxazole, sulfapyridine, testosterone, trimethoprim, and thiamphenicol were detected in all raw wastewaters in μg/L, whereas 45 PPCPs were below the detection limits (<0.02 μg/L) in all samples. Na`ur and Abu Nuseir WWTPs showed high PPCPs removal efficiencies in comparison with AL-Baqa`a, Salt, and Fuhais-Mahis WWTPs. Boqorreya spring showed signs of contamination by Salt WWTP effluents as a result of mixing. Irrigation with effluents showed higher carbamazepine concentrations in soils at the top soil layers (0 to 20 cm) in all farms than its concentrations at the root zone (20 to 40 cm) by using drip irrigation system with various plants. In plants, carbamazepine concentration was only detected in high concentration level in mint leaves. In the same farm, diclofenac concentration was detected only in olives and not in twigs and leaves, indicating a high rate of plant uptake especially during the olive’s growth period. Furthermore, plant fruits, leaves, and stems left on the farm after harvesting are generally consumed by cattle, which means entering the food chain of humans.
Towards a Better Understanding of Long-Term Self-Forming Dynamic Membrane Bioreactor (SFDMBR) Performance: Effect of Aeration Intensity

Published: May 2022

This study aims to provide valuable new insights regarding the effect of aeration intensity on long-term self-forming dynamic membrane bioreactor (SFDMBR) performance and the associated mechanisms. Three identical SFDMBRs, with different aeration intensities (i.e., 200, 500 and 800 L/h), were operated in constant transmembrane (TMP) mode for 60 days. The best chemical oxygen demand (COD) removal performance was achieved at medium aeration intensity, owing to the enhanced COD removal contribution by the self-forming dynamic membrane (SFDM). As expected, the SFDM formation time was extended with increasing aeration intensity. Different from the initial short-term stage results, it was interestingly found that the SFDMBR operated at medium aeration intensity exhibited the best long-term filtration performance, followed in order by the SFDMBRs with low and high aeration intensity, respectively. Further analysis revealed that the governing fouling mechanism transited from biomass accumulation to the increase of specific resistance, as aeration intensity increased. The variation of SFDM-specific resistance was verified with particle size distribution (PSD) data and scanning electron microscopy (SEM) images. The long-term increasing rate of SFDM filtration resistance was consistent with both extracellular polymeric substances (EPS) content and the proteins/polysaccharides (PN/PS) ratio of SFDMs. Internal EPS production was enhanced in the thicker SFDM formed at a lower aeration intensity.

Published: May 2022

Shale in the Wufeng Formation of the upper Ordovician and Longmaxi Formation of lower Silurian in the Sichuan Basin and its surrounding area is widespread. Shale gas resources are abundant. Shale gas in the Wufeng Formation and the Longmaxi Formation in the basin has been a major breakthrough. The basin margin transition zone in southeastern Chongqing is in an intense tectonic activity area, which is more complicated and special than the stable stratum in the basin. Therefore, it is necessary to put forward higher requirements for preservation conditions and enrichment pattern evaluation of shale gas. Therefore, in view of the complicated structural pattern of the basin margin transition zone in southeastern Chongqing, the preservation conditions and reservoir forming patterns are analyzed through structural evolution, uplift and denudation, fault development, structural styles, roof and floor conditions, and formation pressure. The results show that the main reason for the formation of normal pressure is the late uplift, denudation and fault development. The pressure coefficient from the basin to the outer layer is changed from overpressure to normal pressure, and structural transformation forms the preservation form of shale gas with narrow and steep residual anticline, wide residual syncline and residual slope. The preservation condition evaluation of normal shale gas should be based on structural factors such as structural evolution, structural style, uplift and denudation degree and fault development degree, with formation pressure coefficient as reference condition, combined with material basic conditions such as roof and floor conditions and formation thickness. The findings of this study can help for better understanding of the “sweet spot” prediction of normal pressure shale gas in complex structural area.

Published: May 2022

Hand hygiene (HH) serves as a primary public health measure against healthcare-associated infections. During the coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome (SARS) coronavirus 2 (SARS-CoV-2), HH has been fundamentally reinforced for preventing infection transmission globally. This cross-sectional study provides data as a baseline evaluation of knowledge, attitude, and self-reported practice, along with the differences of each between medical and nursing staff. A self-administered questionnaire comprising a standardized World Health Organization Hand Hygiene Knowledge Questionnaire (WHO, revised August 2009) and Likert scales for attitude and practice was employed, using convenience sampling to collect data from 383 healthcare workers (HCWs), 92 nurses (24.9%), and 277 doctors (75.1%) in a tertiary-care military hospital. Both nurses and doctors had moderate knowledge with no significant difference (P = 0.54). Moreover, attitude and practice were reported as moderate for both groups. However, the self-reported HH practice of doctors was significantly (P < 0.05) better than that of nurses, while nurses had significantly better (P < 0.01) attitudes in comparison with doctors. Participants who had received formal training in the previous 3 years were 70.65% among nurses and 44.76% among doctors. In total, 78.36% acknowledged routine use of alcohol-based hand rub. It suggested a relationship of HH to demographic variables, professional role, and departmental service. It should be noted that this study shows no relationship between knowledge and practice, and a negative correlation between knowledge and attitude. Concurrently, while further investigation is required to pinpoint the obstacles to achieving proper HH, it can be concluded that infrastructure promoting its practice among HCWs needs to be established.

Published: May 2022

Coronavirus Disease 2019 (COVID-19) caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) has been declared a pandemic since March 2020. COVID-19 has had an impact on increasing the workload and risk on nurses, thus affecting the level of stress and quality of life of nurses. The purpose of this study was to determine the effect of work stress and quality of life on nurses' turnover intention. This study used an observational analytic design with a cross-sectional design with proportional stratified random sampling of the population of inpatient nurses. The number of samples was 215 respondents using the WHOQOL-Brief Questionnaire and a validated questionnaire. The results showed that the average score of work stress was 3.40 (enough), the average quality of life score was 2.59 (low), and the average score was 3.44 (high). Partial analysis of the work stress variable has a significant and positive impact on turnover intention, while the quality of life variable has a significant and negative impact on turnover intention. Meanwhile, the simultaneous analysis shows that the variables of work stress and quality of life have an impact on turnover intention. This is because during the COVID-19 pandemic there was an increase in workload, work risk and anxiety from nurses. In addition, nurses experience rest disturbances, and a decrease in social activities so that this encourages nurses to leave their jobs during this COVID-19 period.

… and All Men and Women Are Critics or Criticism in a Mirage-Universe

This text/speech is an attempt to provoke discussion or at least thoughts regarding the increasing omnipresence of the false in our reality – something which results in sort of a theatricality in a negative connotation of the word. A theatricality that has always accompanied imposters and surrounded the production of copycats/fake stuff, both in life and in art, especially in comedy. Yet, the false pretending so masterfully to stand for the genuine has for some time already started to be more and more an object of worry and concern rather than of ridicule. Among the most worrying of its many manifestations has been the feeling that we, as human beings, are getting closer and closer, that we are having the world at our fingertips. One of the saddest illusions we so easily succumb to. For, in effect, we have been getting more and more estranged. During the last two years, when we needed to keep a distance and closeness was so much missed, sometimes I thought why we were not as indignant at and horrified by the invisible distancing taking ground between us long time before the pandemic. The centrifugal motion on so many levels has been getting frighteningly strong for a long time already: we have been kind of flying away from each other, mistaking communication for communion, having our bodies touch a lot but less and less experiencing the elevating feeling of our souls embrace. So much so that, I dare say, for many years before the pandemic we have been living in a time of a new Big Bang. Only it is a Big Bang that is taking place not somewhere in the universe but within the mankind itself; a Big Bang that is already happening within our own selves too – within the single human being, since we often start to question our innate sense of what is good or bad, and to what extent something is good or bad. It is like the increasing outside chaos is getting to creep inside us, throwing into disarray our inner moral magnet, that invisible thing that holds us as humanity. Isn’t the mass erosion of criteria a result exactly of an eroding of our innate criteria? How have theatre and criticism been affected by this dwelling of ours in sort of a mirage-universe? How have they responded to the different faces of the false? While trying to open a conversation on this topic, I’ll also try to outline the evolving response of the critics and the search for possible ways-out en route back to the genuine.
The Experience of the Space of Representation and The Distances of Manipulations. Views and Movements of Living Bodies - Puppets - Virtual or Electronic Objects and Bodies
Authors:   Beaux Arts Tournai, Belgique, Flabat Françoise
Published: May 2022

Remembering the essential relationship that exists between the public and the stage in the time of the theatrical performance with traditional puppetry, and the triangulation of the relationship between the viewer and the actor with the puppet object, it is the experience space and distances of play and movement between the living and the inert which are revisited. The contribution of digital arts and the use of technologies in puppet works reveal new original and innovative forms that disturb the landmarks, the presence of living, virtual or robotic bodies. An intuitive text based on a curious need to question the connections between digital arts and the arts of puppetry.

The classical repertoire and, especially, its stage rewritings define a thematic obsession for the great theatre creators of the moment. Just as each great director has their own aesthetic, so each of them has their own way of appropriating representative plays. Henrik Ibsen is one of the indispensable playwrights in the artistic portfolio of the most important names whose creations were performed on the Romanian stages. This article aims at a parallel analysis of two recent versions of the Ibsenian play The Lady from the Sea, directed by Radu Afrim (2014) and Andriy Zholdak (2022), respectively, in order to deepen the specific differences of two theatrical aesthetics decisive for understand the evolution of contemporary theatre. We also aim to question the possibilities that the readaptations, the rewritings of the great classical texts involve in the attempt of the creators to “contemporize” a play representative of the sensitivity of a past century.
Severed Green: a Pandemic-Born Structure

An open letter signed by a large group of Romanian cultural NGOs and published in Scena.ro review (no. 49 (3)/2020) signaled the danger of disappearance of the entire independent cultural sector. The authors reported the authorities’ lack of involvement concerning this sector’s support during the pandemic crisis, the inability of those in a decisional position to understand how it functions or the fact that the artists working here are the innovators that the culture urgently needs. Indeed, the Coronavirus pandemic has hit hard the independent cultural sector, as well as the one formed by entrepreneurs, small or medium-sized businesses. The prolongation of the state of emergency, the new regulations concerning the functioning of performance halls at the capacity of 30-50-70% depending on the evolution of the pandemic have brought the cultural organizations at the brink of bankruptcy. The uncertainty of living and project continuity has existed in our society even under what we now call ”normal conditions”, but in the last two years, this uncertainty increased dramatically. That is why the condition of the Romanian independent artist draws near to the precariat class - a concept widely theorized by the economist Guy Standing - who calls it a dangerous class by the authorities' tendency to ignore it, pushing it into the trap of insecurity, debt and humiliation. Most of the time, however, the freedom of creation is born of external constraints. Independent artists were once again forced to take risks and give birth to hybrid artistic experiments - new forms that renegociate the relationship with the spectators, space and even their own bodies. This presentation aims to analyze the manner in which the work on the show Severed Green (produced by Pro Theatre Association, Zalău, 2020) managed to propose a new dramaturgical direction, which the artistic team named it documented theatre. Situated at the congruence of documentary and classical forms, documented theatre represented a liberating discovery for the practitioners.
Pathogenetic mechanisms of mild traumatic brain injury in patients of different ages

This study was carried out to reveal the influence of mechanical energy, which triggers a whole cascade of pathological and compensatory processes of different depth and duration in the brain in traumatic brain injury (TBI). One of the most common consequences of TBI is impaired working memory – the ability to temporarily hold small pieces of information necessary for current mental activity. The aim of the work is to study the relationship between the TBI mechanism and the types of brain damage, as well as the consequences of trauma in patients of different ages. 95 case histories of patients with closed TBI were studied. All patients were treated in the Neurosurgical department of the Emergency hospital, Chernivtsi. Among them were 76 men and 19 women. The study found that TBI of patients in most cases was obtained as a result of traffic and others accidents. All patients had closed TBI. Contusion foci in all age groups were equally identified in the frontal, temporal and occipital lobes, less in the parietal lobe. The incidence of contusion increased slightly with increasing age of patients. In the presence of hemorrhages in patients, hemiparesis and liquor-hypertensive syndrome occurred. In men, TBI was more common than in women, and was expressed as moderate brain contusion, subacute and chronic compression of the brain. This TBI development was more common in young patients. It is promising to further study the nature of combined TBI in people of all ages and analyze the results of specialized neurosurgical care.
