The work emphasizes the urgency of this problem, the importance of timely and high-quality pre-hospital assistance to victims of road accidents. The purpose was to show the importance of complex, interagency interactions in helping victims on motorways. The existing different tactical schemes to assist victims at the pre-hospital stage were analyzed. The success of the European countries in reducing the level of road accidents has shown their negative consequences compared to the Ukrainian current indicators. Also, the historical example of the constitutional result from the introduction of several provisions and actions in 1985 and 1986 in the USSR to improve pre-emergency care for the injured on the highways. As a result of the introduction of the provisions, the savings from pre-hospital losses amounted to 96.85 % of the total loss of fatalities on motorways. These data show the need to improve the universal organizational scheme of assistance to victims at the pre-hospital stage in Ukraine, which requires significant attention from state structures of different levels.
A Post-traumatic Defense Mechanism on Toni Morrison’s Portrayal of Pecola in The Bluest Eye
Authors: Farah Farhat Tasannum
Published: November 2021

Trauma is a universal experience of human being. The intensity and characteristics of traumatic experiences vary from person to person, culture to culture; and they also depend on the other psycho-socio-cultural variables; and the defense-mechanism has no particular order. In order to making points clearer and focused, this paper has been divided into three subsections. The first section is a narrative essay on trauma and post-traumatic ego defense mechanism. The second part broadly focuses on some common defense mechanism and the third section discusses on a particular defense mechanism, dissociating reality and associates it with the idea of insanity. As a whole, this research paper deals with Post-traumatic Defense Mechanism, focuses on the character of Pecola as a mother in The Bluest Eye by Toni Morrison that reads a deconstructed idea of “insanity” to interpret the character.

Published: November 2021

In this paper, we describe the Skynet Robotic Telescope Network, a network of about 2 dozen small optical telescopes spanning four continents. For a prospective user of the network, we provide details on its operation and mention certain caveats potentially affecting observations taken under the control of Skynet software. The actual performance of the network is demonstrated by long-term observations of two blazars: OJ 49 and 3C 279. We show their photometric light curves acquired with a subset of Skynet telescopes in the 2018/19 observing seasons. Preliminary results of the analysis of the variability of these two targets are given, including the quantitative properties of light variations and the periods of possible Quasi Periodic Oscillations (QPOs) found in the seasonal light curves.
Cosmologías nahua (maseual) y totonaca (tutunakú) de la Sierra Norte de Puebla (México) Segunda parte: las ‘almas’, los dueños, las fuerzas maléficas
Authors: Beaucage Pierre , Rojas Mora Xanath
Published: November 2021

Continuando nuestra comparación entre las cosmologías indígenas de la Sierra Norte de Puebla (ver Beaucage y Rojas Mora 2021), e-
 xaminamos aquí, a partir de relatos y testimonios, los encuentros entre los humanos y los entes sobrenaturales que quedaron en el mundo una vez terminado el tiempo de la creación: Dueños de la Tierra, del Agua, del Fuego, y también seres malignos como los Aires y los tepeuanij. Esos encuentros a menudo tienen consecuencias sobre la salud, el ‘susto’ siendo la más común, pero no la única. Para entender esa patología espiritual y los tratamientos realizados por curanderos y chamanes, empezamos por aclarar la concepción de los ‘centros y entidades anímicas’ en las culturas nahua y totonaca. Distinguimos a tres: el ‘espíritu/corazón/alma’, la ‘sombra’ y el ‘doble animal’. Las fuerzas cósmicas afectan estas entidades de forma distinta y los tratamientos varían en consecuencia. Nuestro estudio pone a la luz diferencias
 importantes en conceptos y prácticas entre nahuas y totonacos, pero también variaciones entre comunidades de una etnia determinada. Se necesitan más estudios de caso para poder estimar bien la amplitud de estas diferencias.

In this study, a total of 228 raw meat samples (pork: 76, beef: 76, chicken: 76) and 301 raw seafood samples (fish: 199, shrimp: 67, squid: 35) were collected randomly at traditional markets in Ho Chi Minh City (Vietnam). In meat, the ratio of Salmonella spp. was 70.61% (161/228). Among the contaminated meat samples, pork was infected with a ratio of 90.79 % (69/76) while the contamination ratios in beef and chicken were 43.42% (33/76) and 77.63% (59/76), respectively. Salmonella contamination was detected in fish (40.20%), shrimp (7.46%) and squid (17.14%). Because of sulfonamide group is used in Salmonella treatment, the study focused on sulfonamide resistance. In fresh seafood comparison, there were 32.56%, 40% and 10% Salmonella showing resistance to sulfamethoxazol in fish, squid and shrimp, respectively. In fresh meat comparison, there were 31.58%, 16.67% and 55.56% Salmonella showing resistance to sulfamethoxazol in pork, beef and chicken, respectively. Interestingly, there were 21 serovars including 19 identified serovars including S. Kentucky (8), S. Agona (2), S. Infanis (4), S. Saintpaul (1), S. Indiana (1), S. Braenderup (1), S. Potsman (2) and 2 unidentified serovars showing different phenotype to this antibiotic. Among the 21 serovars, only 23.81% strains carried both genes (sul1, sul2). For the sul1 gene, 61.9% strains were presented while sul2 occupied at a lower rate than sul1 with the rate of 52.38%. The study is very interesting and useful to go more functional analysis in sulfonamide resistance.

Published: November 2021

Bacterial infections represent a very serious problem that threatens human health, antibiotics were designed to attack the causative agents of infectious diseases, but some bacterial pathogens became virulent and resistant to antibiotics by different mechanisms, resistance genes represented one of those mechanisms. This study attempts to screen the existence of five different resistance genes (mecA, TEM, FemA, MexD, and AmpC) among 25 bacterial isolates divided into two groups the first was non-clinical bacterial type strains including Bacillus subtilis, Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa, Salmonella typhi, and the other group includes some clinical bacterial isolates. Evaluation of their susceptibilities to different 12 antibiotic discs and attempting to find the relationship between genotype and phenotype assessment. Different responses were reported which varied from slightly susceptible to multidrug-resistant such as P. aeruginosa and K. pneumonia which could be considered as multidrug-resistant strains. Therefore, detection of resistance gene became crucial and critical to recognize the mechanism of resistance, five pairs of primers were included to investigate five responsible genes belonging to beta-lactamases, efflux pump, and methicillin resistance. Conclusively, the PCR technique is a very accurate tool to check the genetic resistance whether being expressed to phenotype or not. Moreover, the clinical bacterial isolates appeared more resistant that reflecting the impact of the surrounding environment on bacterial behavior.
The Impact of GST on Indian Economy
Authors: Navandhar Rohan
Published: November 2021

Abstract: In India, the idea of GST was contemplated in 2004 by the Task Force on implementation of the Fiscal Responsibility and Budget Management Act, 2003, named Kelkar Committee. The Kelkar Committee was convinced that a dual GST system shall be able to tax almost all the goods and services and the Indian economy shall be able to have wider market of tax base, improve revenue collection through levying and collection of indirect tax and more pragmatic approach of efficient resource allocation. Under the Goods and Service Tax , every person is be liable to pay tax on output and shall be entitled to enjoy credit on input tax paid and tax shall be only on the amount of value added. GST is a single national uniform tax levied across India on all goods and services. In GST, all Indirect taxes such as excise duty, central sales tax (CST)and value- added tax (VAT) etc. will be subsumed under a single regime. Introduction of The Goods and Services Tax (GST) expected as a significant step towards a comprehensive indirect tax reform in the country, which would lead India for its economic growth. The Proposed study is designed to know the impact on GST on Indian Economy with the Help of Its individual effect on different sectors. Under GST, goods and services fall under five tax categories: 0 per cent, 5 per cent, 12 per cent, 18 per cent and 28 per cent. For corporates, the elimination of multiple taxes will improve the ease of doing business. And for consumers, the biggest advantage would be in terms of a reduction in the overall tax burden on goods. "Inflation will come down, tax avoidance will be difficult, India's GDP will be benefitted and extra resources will be used for welfare of poor and weaker section. The Lok Sabha has finally Passed the Goods and Services Tax Bill and it is expected to have a significant impact on every industry and every consumer. Apart from filling the loopholes of the current system, it is also aimed at boosting the Indian economy.

Published: November 2021

Abstract: The popularity of online shopping is growing day by day. In financial year 2021, over 40 billion digital transactions worth more than a quadrillion Indian rupees were recorded across the country. As the number of credit card users rise world- wide, the opportunities for attackers to steal credit card details and subsequently, commit fraud are also increasing. Since humans tend to exhibit specific behavioristic profiles, every cardholder can be represented by a set of patterns containing information about the typical purchase category, the time since the last purchase, the amount of money spent etc. So these frauds can be detected through various algorithms mainly random forest and logistic regression. To enhance the boost and build model with much more efficiency adaboost is also added. Keywords: Fraud detection, behavioristic profile, random forest, logistic regression, adaboost

Authors: Arora Sakshi P.
Published: November 2021

There was abnormal uterine bleeding and recurrent lower abdominal pain in a 50 year-old female. A bilateral salpingo-oophorectomy is surgery to extract ovaries and fallopian tubes of both the sides. By the age of 60, more than a third of women in the US have had a hysterectomy. The expected anatomy, the patient's body habits, the degree of pelvic relaxation, the need for concurrent abdominal and vaginal procedures, and the surgeon's expertise all play a role in deciding the uterus delivery technique and route. The hysterectomy and bilateral salpingo-oophorectomy will both be done during one procedure. The uterus, ovaries, cervix & fallopian tubes are remove through surgery. For a large sub mucous fibroid uterus, the patient opted to have a complete abdominal hysterectomy along bilateral salpingo-oophorectomy. Abdominal hysterectomy & bilateral salpingo-oophorectomy were performed in midline vertical incision under general anesthesia. A uterus with sub mucous fibroid (polyps) was confirmed by pathology. The option of surgical method in a hysterectomy based on clinical conditions, the professional skill of the surgeon, and the preference of patients. As this case indicates, for many patients, abdominal hysterectomy is an important choice where the use of other methods may pose a serious danger. This method may be sufficient for the treatment of sub-mucous fibroids. There are broad range of studies that demonstrate beneficial effects in the various therapies created, serving as a basis for guiding physiotherapeutic approaches in hysterectomy, aiming at complementary tools for better treatment of the patient undergoing this procedure.

Authors: Umamaheswari S.
Published: November 2021

Fermented rice water is a classic example of fermented food known for nutritional values. The microbiome of fermented rice water is not yet completely revealed. Helicobacter pylori, the causative organism of peptic ulcer and gastric cancer is considered as a WHO priority-2 due to the nature of resisting antibiotics necessitating the research to rule out regiments to avoid H. pylori infections. Probiotics are considered as an emerging alternative to eradicate and manage this pathogen, making it more prominent to have the means to evaluate their effectiveness against this pathogen. The present work is focused on revealing the microbial communities of fermented rice water and to characterize the isolates for their probiotic efficiency along with its antagonistic activity against H. pylori. Three natural inhabitants of fermented rice water were isolated and characterized morphologically and biochemically and were identified using 16s rRNA sequencing. The isolates were further tested for their probiotic efficiency and their antagonistic activity against H. pylori isolated from the gastric endoscopic ulcer samples. The present study highlights Enterococcus hirae as a probiotic strain with potent anti-H. pylori activity.

Authors: Roy Tathagata
Published: November 2021

Iatrogenic or drug induced disease is of great clinical significance in therapeutics. Treatment with antidepressants like selective serotonin reuptake inhibitors (SSRIs) and antipsychotics reveal Bruxism (excessive grinding and clenching of the teeth) as such type of iatrogenic disease, however it is rarely found with atypical antipsychotic drugs like Olanzapine. A 50-year male patient, suffering from schizophrenia was under regular antipsychotic medication receiving Tab. Olanzapine 5 mg O.D., Tab. Clonazepam 0.5 mg O.D. regularly for past 25 years. Recently he gradually developed excessive grinding and clenching of teeth despite of any dental and ENT clinical complications. Biochemical and hematological tests also showed normal result. On admission with the complication of bruxism, tab. Olanzapine dose was reduced to 2.5 mg OD, however even after dose reduction there was not much improvement in bruxism. On the 4th day of the admission tab. Olanzapine has been substituted with tab. Clozapine 50 mg TDS. After 1 week of withdrawal of Olanzapine there was no complain of bruxism and he was discharged. On follow up after 1month the complication was occasional. Causality assessment revealed a probable relation between Olanzapine and Bruxism. Though among the atypical neuroleptics, extrapyramidal side effects are thought to be less common with olanzapine, but it may cause fatal consequences. Therefore, this case study and proper investigation may be helpful in designing the treatment strategy in more effective way and also aware all the healthcare professionals to monitor the patients on neuroleptics.

Authors: Cho Sung-Min , Al-Kawaz Mais , Shou Benjamin , Prokupets Rochelle , Whitman Glenn , Geocadin Romergryko
Published: November 2021

Background: Patients with venoarterial extracorporeal membrane
oxygenation (VA-ECMO) are at risk of cerebral reperfusion injury after
prolonged hypoperfusion and immediate restoration of systemic blood
flow. We aimed to examine the impact of mild hypothermia during the
first 24 hours post-ECMO on neurological outcome in VA-ECMO patients.
Methods: This was a retrospective study of adult VA-ECMO
patients from a tertiary care center. Mild hypothermia was defined as
32-36°C during the first 24 hours post-ECMO. Primary outcome was good
neurological function at discharge measured by a modified Rankin Scale
≤3. Multivariable logistic regression analysis was performed for primary
outcome adjusting for pre-specified covariates. Results:
Overall, 128 consecutive patients with VA-ECMO support (median age: 60
years and 63% males) were included. Within the first 24 hours of
VA-ECMO cannulation, we found a median of 71 readings per patient
(interquartile range 45-88). Eighty-eight patients (68.8%) experienced
mild hypothermia within the first 24 hours while 18 of those 88 patients
(14.2%) had a mean temperature<36°C. ECMO indications
included post-cardiotomy shock (39.8%), cardiac arrest (29.7%), and
cardiogenic shock (26.6%). Duration of mild hypothermia, but not mean
temperature, was independently associated with increased odds of good
neurological outcome at discharge (Odds Ratio [OR]=1.16, 95%
Confidence Interval [CI]=1.04-1.31, p=0.01) after adjusting for age,
severity of illness, post-ECMO systemic hemorrhage, post-cardiotomy
shock, acute brain injury, and mean 24-hour PaO .
Neither duration of mild hypothermia (OR=0.93, CI=0.84-1.03, p=0.17) nor
mean temperature (OR=0.78, CI=0.29-2.08, p=0.62) was significantly
associated with mortality. Similarly, duration of mild hypothermia
(p=0.47) and mean 24-hour temperature (p=0.76) were not significantly
associated with frequency of systemic hemorrhages. Conclusions:
In this single center study, longer duration of mild hypothermia during
the first 24 hours of ECMO support was significantly associated with
improved neurological outcome. Mild hypothermia was not associated with
an increased risk of systemic hemorrhage or improved survival.
Proximity inductive dimension and Brouwer dimension agree on compact Hausdorff spaces
Authors: Siegert Jeremy
Published: November 2021

We show that the proximity inductive dimension defined by Isbell agrees with
the Brouwer dimension originally described by Brouwer (for Polish spaces
without isolated points) on the class of compact Hausdorff spaces. This shows
that Fedorchuk?s example of a compact Hausdorff space whose Brouwer dimension
exceeds its Lebesgue covering dimension is an example of a space whose
proximity inductive dimension exceeds its proximity dimension as defined by
Smirnov. This answers Isbell?s question of whether or not proximity
inductive dimension and proximity dimension coincide.
A classification of generalized derivations in rings with involution

Published: November 2021

Let R be a ring. An additive mapping F : R ? R is called a generalized
derivation if there exists a derivation d of R such that F(xy) = F(x)y +
xd(y) for all x,y ? R. The main purpose of this paper is to characterize
some specific classes of generalized derivations of rings. Precisely, we
describe the structure of generalized derivations of noncommutative prime
rings with involution that belong to a particular class of generalized
derivations. Consequently, some recent results in this line of investigation
have been extended. Moreover, some suitable examples showing that the
assumed hypotheses are crucial, are also given.

On S-2-absorbing primary submodules
Authors: Naji Osama
Published: November 2021

This article introduces the concept of S-2-absorbing primary submodule as a
generalization of 2-absorbing primary submodule. Let S be a multiplicatively
closed subset of a ring R and M an R-module. A proper submodule N of M is
said to be an S-2-absorbing primary submodule of M if (N :R M) ? S = ? and
there exists a fixed element s ? S such that whenever abm ? N for some a,b
? R and m ? M, then either sam ? N or sbm ? N or sab ? ?(N :R M). We give
several examples, properties and characterizations related to the concept.
Moreover, we investigate the conditions that force a submodule to be
S-2-absorbing primary.

Published: November 2021

This paper introduces fundamental ideas of bitopological dynamical systems.
Here, notions of bitopological transitivity, point transitivity, pairwise
iterated compactness, weakly bitopological transitivity, etc. are
introduced. Later, it is shown that under pairwise homeomorphism, weakly
point transitivity implies weakly bitopological transitivity. Moreover,
under pairwise homeomorphism; pairwise compactness and pairwise iterated
compactness are found to be equivalent. Later, we apply our results in the
development process of a human embryo from the zygote until birth. During
the process of biological application, we disprove conjecture 1 of Nada and
Zohny [S. I. Nada, H. Zohny, An application of relative topology in biology.

then we obtain information about the structure of R and describe the all
possible forms of the maps F, G and H. This result generalizes many known
results recently proved by several authors ([1], [4], [5], [8], [9], [13],

Oscillation and nonoscillation theories play very important roles in gaining
information about the long-time behavior of solutions of a system.
Therefore, we investigate the asymptotic behavior of nonoscillatory
solutions as well as the existence of such solutions so that one can
determine the limit behavior. For the existence, we use some fixed point
theorems such as Schauder?s fixed point theorem and the Knaster fixed point
theorem.

algebras which are the dendriform version of 3-pre-Lie algebras. In fact
they are the algebraic structures behind the O-operator of 3-pre-Lie
algebras. They can be also regarded as the ternary analogous of L-dendriform
algebras. Moreover, we study the generalized derivations of 3-L-dendriform
algebras. Finally, we explore the spaces of quasi-derivations, the centroids

Secondary lymphedema refers to a condition in which the affected extremity develops progressive hypertrophy due to lymphatic fluid retention. Worldwide, secondary lymphedema is most often associated with parasitic infection; within the United States, secondary lymphedema is most often caused by surgical disruption of the lymphatic drainage basins due to cancer surgery and/or radiation. For patients with lymphedema secondary to parasitic infection, treatment of the offending infectious organism (Wuchereria bancroftii) is critical. For patients with surgical disruption of the lymphatic drainage basin(s), patients are first managed non-operatively with compression and manual lymphatic drainage massage. Over the past decade, surgical techniques have been developed and implemented to improve lymphatic drainage for patients with post-surgical secondary lymphedema. These procedures, including lymphovenous bypass or vascularized lymph node transfer, are aimed at reconstituting lymphatic drainage and reducing lymphatic retention to alleviate early lymphedema. An appreciation of the underlying physiology responsible for secondary lymphedema, and diagnosis and management is required to provide timely and appropriate care for these patients.

2020 yılında Çin’in Hubei eyaletinin Vuhan şehrinden neredeyse tüm ülkelere yayılan Covid-19 (SARS-CoV-2 Enfeksiyonu)’un potansiyel tehlikeleri, dünya çapında bilim insanlarının ilgi odağı olmuştur. Covid-19’un pnömoniden ağır akut solunum yolu enfeksiyonlarına ve böbrek yetmezliğinden ölüme kadar uzanan ciddi etki süreçleri milyonlarca insan için tehdidini sürdürmektedir. Ortaya çıkan yeni viral enfeksiyonlarda uygun tedavi protokollerinin geliştirilmesi için pandemik türlerin izolasyonu büyük önem arz etmektedir. Bunun için yeni yöntemlerin yanında mevcut yöntemlerin de geliştirilmesi gereklidir. Virüsler doğada canlı formda bulunmazlar ve genetik materyalini aktarabilmek için başka canlılara ihtiyaç duyarlar. Ayrıca izole edilmiş yüzeylerde hızla inaktif hale getirilebilirler. Bu yönüyle su kaynakları ve hava en önemli iletim vasıtaları olarak karşımıza çıkmaktadır. Virüslerin yayılmasının önüne geçmede ve onları etkisiz hale getirmede iletim vasıtalarına yönelik adsorpsiyon işlemleri uygulanabilmektedir. Bu derlemede, virüslerin karbonlu, oksitli, gözenekli materyaller ve metal organik kafes yapıları içeren çeşitli adsorbanlarla etkileşimleri incelendi. Su ve hava arıtmasında kullanılan adsorbanların hedef türleri adsorplama işlemlerinde elektrostatik etkileşimlerin daha etkili olduğu belirlendi. Virüs yüzeyinin çeşitli organik fonksiyonel grupları taşıması nedeniyle farklı adsorbanlar ile elektrostatik etkileşime geçeceği ve bu şekilde de onların uzaklaştırılarak hem izole edilmesi hem de etkisiz hale getirilmesi mümkün görülmektedir. Çalışmamızın Koronavirüsler dahil diğer patojenlerin hava ve su kaynaklarına uygulanacak adsorpsiyon işlemleri ile yayılmalarının engellenmesine ve belirtilen iletim vasıtalarının dezenfekte edilmesine yönelik etkili çözümlere katkı sağlayacağını düşünmekteyiz.
«Slike mødre»: Barnevernets stigmatisering av sårbare familier i dagens Russland
Authors: Ofitserova Trine Skogset

Abstract in English“That kind of mother”: Stigmatisation by the Russian child protection servicesHow does stigma influence the extent to which the child protection services in Russia undertake preventative work with vulnerable families in order to avoid taking the child out the family? Based on an analysis of previous research and my own fieldwork from St. Petersburg and Moscow, I note the gap between expectations towards vulnerable families, and their actual living conditions and potential for meeting these expectations. This gap results in a stigmatising categorisation of families who find themselves marginalised as neblagopolutsjnye – socially disadvantaged. Although Russia’s officially ‘family-oriented’ child protection system is expected to base its work on objective methods, stigmatisation influences the decisions of social workers, making the system risk-oriented in practice. This is due to little or inadequate specialised education among social workers, resulting in the strong presence of the human factor: subjective, non-professional evaluations are made. With scant intersectional cooperation among state actors, there is little space to counteract or modify subjective evaluations. Thus, stigmatisation serves to limit the extent to which vulnerable families in Russia receive help, thus creating and upholding ‘social orphanhood’.

La presente investigación se originó por la inquietud de un grupo de estudiantes de la generación 2019-2021 de un curso de posgrado en Innovación Educativa. Ellos buscaban a través de la experiencia académica conocer, aprender, generar, desarrollar y aplicar estrategias didácticas para implementar en la maestría en Innovación Educativa. La problemática se identificó como la carencia o ausencia de infraestructura educativa y material didáctico en las instituciones de educación superior (IES) para orientar los procesos educativos en función de la estimulación de los canales perceptivos de los estudiantes, mediante el óptimo diseño de los espacios educativos de las IES. Por tanto, el objetivo de este trabajo fue identificar los criterios constructivistas pertinentes a través de un procedimiento sistematizado que promueva la modificación continua y permanente de los espacios educativos en las IES. La metodología seleccionada fue cualitativa, mediante la documentación de la técnica de estudio de caso. Asimismo, se empleó la heurística como herramienta de búsqueda y discriminación de la información hallada en la investigación documental. Durante el desarrollo, los hallazgos se presentaron al docente y a los estudiantes de la clase en equipos disciplinarios, para lo cual se realizaron anotaciones grupales en una tabla de términos y conceptos que permitió determinar elementos comunes y reincidentes. Posteriormente, se ejecutó un análisis grupal y multidisciplinario de la información recabada en el cuadro comparativo. Los resultados conseguidos aportaron criterios suficientes para recomendar el diseño de espacios educativos en las IES, así como elementos didácticos que predispongan y motiven a los estudiantes hacia el aprendizaje. Por todo lo anterior, se concluye que el presente documento es una propuesta que sistematiza un conjunto de actividades incluyentes (procedimiento) para el diseño de los espacios educativos de las IES desde la perspectiva de los estudios de posgrado en innovación educativa.

The possibility of increasing the efficiency of municipal wastewater treatment plant (WWTP) operation by changing the flow diagram of biological wastewater treatment in aeration tanks at minimum expenses for their reconstruction is shown in the paper on the example of one of the regional centres of Ukraine. The technology of nitri-denitrification of wastewater according to the flow diagram of the two-stage modified Ludzak-Ettinger process is offered for the considered conditions. The distribution of wastewater flows and internal nitrate recycling between the individual stages of this flow diagram has been optimized in order to minimize the residual content of total nitrogen in the treated effluents. Computer dynamic modelling of biochemical processes has proved the high efficiency and reliability of the flow diagram proposed by the authors.
