Voltaire’s Comedy The Prodigal Son in Dostoevsky’s Novel The Adolescent
Authors: Magaril-Il’iaeva Tatiana G.
Published: November 2021

Through the example of Voltaire’s comedy The Prodigal Son, the article shows how Dostoevsky actualizes the worldview and life strategies behind the imagery of other authors, when using their texts in his novel The Adolescent. Nonetheless, Dostoevsky, not only reproposes several different perspectives, but also engages in a dialogue with them and transforms them according to his aim as. Dostoevsky thoroughly weaves the slightly mentioned comedy by the French philosopher into the fabric of the text, and the writer works with it in several mutually dependent directions at once. The quote (taken from the preface, not from the play) stresses the matters that are raised in the preface and the preface itself as a significant element of the composition. The French sentence borrowed by Versilov relates his image with Voltaire’s, as it was perceived by Dostoevsky. In the novel Dostoevsky reflects on the motif of the prodigal son as it is presented in the Bible and also in its transformed version by Voltaire.
The Adolescent by Fyodor Dostoevsky: Current State of Research
Authors: Borisova Valentina V.
Published: November 2021

The review analyses the current state of research of Fyodor Dostoevsky’s novel The Adolescent. The starting point is the tradition of academic commentaries to the text, which allowed achievements in textual criticism during the 1960-1970s. Today we are obviously facing a new turn in both textual studies and commentaries to the novel. The main trends indicate that researchers aim at discovering the spiritual meaning of The Adolescent, its poetics, and sources. Nevertheless, contemporary surveys are characterized by a diversity of academic discourses, originated from psychology, history, cultural studies, linguistics, etc. In the field of literary studies, both Russian and foreign works show a rising interest in the poetics and the analysis of the role of the Christian tradition in the novel. Traditionally, the novel is studied within the prospective Dostoevsky’s Five great works. Monographs reveal the artistic success and unique character of The Adolescent and integrate it into the meta-text of Dostoevsky’s life and oeuvre, giving a variety of typological reasons. Academic research maintains a typological and comparative-historical approach to this novel, though its literary context has not significantly expanded. A substantial aspect of Dostoevsky’s studies is dedicated to the narratology of The Adolescent and its genre features; the traditional definition of the book as a Bildungsroman has now gained a new modified formula. The article pays close attention to the few existing monographs that concentrate on The Adolescent. The article not only provides a review that helps understand how the novel is studied today but outlines prospects of research. Dostoevsky’s novel is organized as a multilayer reality. Therefore, it requires a complex approach - biographical, historical, literary, and mythopoetic (broadly speaking) – in order to allow a full reception of the novel The Adolescent, especially in the mass culture.

Confession and Writing in Dostoevsky’s Novel The Adolescent
Authors: Ghidini Maria Candida
Published: November 2021

This article analyses the specificity of Dostoevsky’s confessional prose, focusing on the novel The Adolescent. Dostoevsky can be defined as a superconfessional author, but he is characterized by a certain suspicion, and a certain mistrustfulness towards the very process of confession is typical of him. The article attempts to show that this apparent paradox has its origins in the modern context in which Dostoevsky operates, when religious, sacramental confession gives way to a psychological practice of self-affirmation.
“I Don’t Like Sunsets”: The Semantics of the Symbol of the Sunset in Dostoevsky’s Novel The Adolescent
Authors: Gazheva Inna D.
Published: November 2021

The article is the continuation of a study on the symbols of sunset in Dostoevsky’s works. Developing the idea of the ambivalence of the Unfading Light, the author shows how this idea is revealed in the novel The Adolescent. The originality of its disclosure is determined by the diegetic form of narration and the age-related psychology of the character-narrator, which is unique for Dostoevsky’s novels. Inclined to attach an exaggerated importance to his own thoughts and feelings, the adolescent captures and analyzes in detail his reactions to the light of the setting sun. This makes it possible to trace their dynamics, which corresponds to the dynamics of his growing up. It is noted that the semantics of the symbols of sunset is explicated not only in monologic episodes but also in the scenes that are seen through the eyes of Arkady. In these episodes, the semantics of the symbol is revealed indirectly: being hidden for the characters themselves (including the diegetic narrator), it is revealed to the reader through the description of their external actions and reactions. At the same time, the reader is prepared to comprehend the symbolic meaning of the image through reflections of Arkady, who definitely does not like the sunset in the first part of the novel and is able to joyfully react to it after the encounter with Makar. The appearance of this character in the novel significantly increases its “luminosity”: all scenes and monologic episodes, which reveal the ambivalence of the symbols of sunset, are concentrated in the third part of the novel and prepare that major chord of universal reconciliation and incipient transformation that sounds in the finale.
Tarnished Virtues: From Richardson to Beardsley
Authors: Boborykina Tatiana A.
Published: November 2021

The starting point of the article is a statement about “tarnished virtues” by one of the characters of Poor Folk, Fyodor Dostoevsky’s first novel. The word combination evokes various associations, allusions, and numerous variants of interpretation. A remark on virtues made in the frame of an epistolary novel immediately recalls the novels of a coryphaeus of the genre, 18th-Century English writer Samuel Richardson, especially his first one, in which the word “virtue” appears in the title – Pamela Or, Virtue Rewarded. However, Richardson’s comprehension of virtue seems to be quite narrow, a fact that had been already noticed by his contemporary writer Henry Fielding, who wrote a parody on Pamela. A brief analysis of the parody discovers a common vision on the nature of virtue by both Fielding and Dostoevsky, which becomes even clearer when one finds out their mutual reference point – Cervantes’ Don Quixote. The article explores other novels by Richardson, his influence upon European literature as well as his inner correlation with such writers as Karamzin and Pushkin. Besides, the article investigates the question – raised by its author some years ago – of a certain similarity between the plotlines of Clarissa and Poor Folk, the appearance of “Lovelace” in Dostoevsky’s first book, and the sudden turn of the plot from Richardson’s glorification of virtue to Dostoevsky’s dramatic realism. A few interpretations of Poor Folk are briefly analyzed, including that of Aubrey Beardsley, who illustrated the novel. Several explanations of the sentence on “tarnished virtues” are explored, and finally, the author offers a new one.
Pharmacodynamic modeling and exposure-response assessment of inebilizumab in subjects with neuromyelitis optica spectrum disorders
Authors: Yan Li , Wang Bing , She Dewei , Mitchel Ben , Criste Ryan , Cimbora Daniel , Katz Eliezer , Rees William
Published: November 2021

AIM: Neuromyelitis optica spectrum disorders (NMOSD) is an
autoantibody-mediated, B cell-driven disease. Inebilizumab is a
humanized, affinity-optimized, afucosylated IgG1 kappa monoclonal
antibody that binds to the B cell specific surface antigen CD19,
resulting in rapid, profound, and sustained depletion of circulating
peripheral B cells in NMOSD subjects (pivotal study). The objective of
this study was to conduct population modeling of B cell response
following inebilizumab treatment in adult subjects with NMOSD, and to
assess the impact of drug exposure to outcome. METHODS: A hematopoietic
transit model was developed to describe the joint effects of reducing
influx from pro-B cells and accelerating CD20+ B cell depletion in the
blood by inebilizumab. Furthermore, the relationships between
inebilizumab pharmacokinetic (PK) exposure and the primary efficacy
endpoint and key secondary efficacy endpoints were evaluated. KEY
RESULTS: At the 300 mg dose, there was no apparent relationship between
efficacy (reduction in disease attack risk, risk of worsening from
baseline in Expanded Disability Status Scale, cumulative total active
MRI lesions, and the number of NMOSD-related in-patient
hospitalizations) and PK exposure. Subjects with low, medium, and high
PK exposure had a similar hazard ratio of NMOSD attack vs placebo group.
CONCLUSIONS: The pharmacodynamic modeling confirmed effective depletion
of B cells is achieved with a 300 mg intravenous dose of inebilizumab
administered on Day 1 and Day 15 and every 6 months thereafter. The PK
variability between patients had no apparent effect on clinical
efficacy.
Coronary sinus electrogram characteristics predicts termination of AF with ablation and long-term clinical outcome.
Authors: Honarbakhsh Shohreh , Schilling Richard , Keating Emily , Finlay Malcolm , Hunter Ross
Published: November 2021

Introduction- Markers predicting AF termination and freedom from
AF/atrial tachycardia (AT) has been proposed. The role of CS electrogram
characteristics has not yet been evaluated. Methods- Patients undergoing
ablation for persistent AF as part of the Stochastic Trajectory Analysis
of Ranked signals mapping study were included. Novel CS electrogram
characteristics including CS cycle length variability (CLV) and CS
activation pattern stability (APS) and proportion of low voltage zones
(LVZs) were reviewed as potential predictors for AF termination on
ablation and freedom from AF/AT during follow-up. The relationship
between localized driver characteristics and CS electrogram
characteristics were also assessed. Results- Sixty-five patients were
included. AF termination was achieved in 51 patients and 80% of
patients were free from AF/AT during a follow-up of 29.5±3.7 months. CS
CLV of <30ms, CS APS of ≥30% and proportion of LVZ
<30% showed a high diagnostic accuracy in predicting AF
termination on ablation and freedom from AF/AT during follow-up (CS CLV
OR 25.6, AUC 0.91; CS APS OR 15.9, AUC 0.94; proportion of LVZs OR 21.4,
AUC 0.88). These markers were independent predictors of AF termination
on ablation and AF/AT recurrence during follow-up. Ablation of a smaller
number of drivers that demonstrate greater dominance strongly correlate
with greater CS organization. Conclusions- Novel CS electrogram
characteristics were independent predictors of AF termination and AF/AT
recurrence during follow-up. These markers can potentially aid in
predicting outcomes and guide ablation and follow-up strategies.

Published: November 2021

Objective To study pain symptoms and their correlation with the
anatomical location (and extent) of deep endometriosis lesion(s)
classified by the Enzian score. Design Prospective multi-centre study
Setting Web-based application called EQUSUM (www.equsum.org) to classify
and report surgical procedures Population or Sample A total of 419
surgical DE (deep endometriosis) cases Methods Collection of surgical
data in DE cases and their endometriosis classification and pain scores.
Main Outcome Measures Preoperative reported pain scores in each domain
(dysmenorrhea, dyschezia, dysuria, dyspareunia, chronic pelvic pain)
were collected along with the Enzian classification. Baseline
characteristics, pain scores, surgical procedure and extent of the
disease were also collected. Results In general, more extensive
involvement of DE does not lead to an increase in numerical rating scale
for pain measures. However, dysuria and bladder involvement do show a
clear correlation AUC 0.62 (SE 0.04, CI 0.54-0.71, p< 0.01).
Regarding the predictive value of dyschezia, we found a weak, but
significant correlation with ureteric involvement; AUC 0.60 (SE 0.04, CI
0.53-0.67, p< 0.01). Conclusions Pain symptoms poorly
correlate with anatomical locations of deep endometriosis in almost all
pain scores, with the exception of bladder involvement and dysuria which
did show a correlation. Also dyschezia seems to have predictive value
for DE ureteric involvement and therefore MRI or ultrasound imaging
(ureter and kidney) is recommended in the preoperative workup in these
patients.

Published: November 2021

This paper reports on the scaling-up of a one-step methanol production
process from the laboratory scale to the pilot scale. This lays the
foundation for the industrialization of a one-step process for preparing
DMM from methanol. After a long period of operation in the circulating
fluidized bed, the Fe-Mo/HZSM-5 catalyst was shown to have high
stability and carbon deposition resistance, and the regeneration effect
of the circulating regeneration fluidized bed was better. In addition,
in-situ DRIFTS was used to explore the effects of reaction time, the
Mo-Fe ratio and carrier Si-Al ratio on the reaction and product
distribution. It was found that the synergistic effect of oxidation
centers and acid centers was the fundamental reason for the excellent
catalytic performance of the Fe-Mo/HZSM-5 catalyst. And proposed the
reaction mechanisms in the one-step synthesis of methylal via methanol
oxidation.

The coffee powder has inherent capabilities as an antioxidant, anti-inflammatory, and antimicrobial. It is a topical wound dressing for acute and chronic wounds, encouraging results different from the wound dressing known today. It is named the new paradigm of wound management. The study of coffee powder since 2003 as a topical wound dressing has created an understanding condemn to disturb the cells in the wound bed. A thin layer of coffee powder should stay in place to ensure safety, covering superficial wound cells’ growth. The remained thin layer of coffee powder has created minimum detached wound cells. Wound healing provides effectiveness for acute and chronic wounds resulted in low cost, easy to get, acceptable scar, non-traumatic, pleasant scent, and not scary to the patients. The utilization of antioxidant, anti-inflammatory, and antibacterial capacities anticipates the injury of the new growth of epithelial cells at the wound bed. It makes better cell proliferation, proper scar formation and safe naturally. Its simplicity in wound management procedures helps improve public health efforts. Hence, it suggested that the coffee powder has the capabilities of the best topical wound dressing.

The requirement of long span bridge is increase with development of infrastructure facility in every nation. Long span bridge could be achieved with use of high strength materials and innovative techniques for analysis of bridge. Generally, cable-supported bridges comprise both suspension and cable-stayed bridges. Cable-supported bridges are very flexible in behavior. These flexible systems are susceptible to the dynamic effects of wind and earthquake loads. The cable-stayed bridge could provide more rigidity due to the presence of tensed cable stays as a force resistance element.
Vehicular Analysis of a Bridge Structure Considering IRC Loading Condition using Sap 2000
Authors: Singh Nikhil Kumar , Yadav Jyoti
Published: November 2021

A beam bridge is a bridge that uses struts as a method of supporting the deck. A bridge consists of three sections: the foundation consisting of protrusions and supports and the substructure consisting of protrusions and quay and the superstructure (bracing, cantilever or curve) and the deck. A beam bridge is probably the most manufactured and used bridge on the planet. Its basic plant, at its best, can be likened to a tree trunk extending to one side to alternate across a stream or river. All decks consist of two main parts: the substructure and the superstructure. The superstructure is everything from the support cushions to - it's the thing that supports the posts and it's the most distinctive part of the deck. The substructure is the device that exchanges the poles of the superstructure on the ground. The two sections must work together to form a strong and durable bridge. Prestressed concrete is basically concrete where the internal concern is reasonable and the pressure propagation created by the external load is concentrated to the desired extent. In this research, we analyze a beam bridge with the effect of prestressed concrete and compare it to a generic deck bridge. Regarding the finite element analysis, the analysis of forces and costs. Here it is concluded that the implementation of a prestressed ceiling results in an economical, stable and load-resistant element.
Experimental Study for Energy Dissipation Using Stilling Basin with One and Two Consecutive Drops
Authors: Qassem H. Jalut  , F. El-Baaja Nagla
Published: November 2021

The scour at downstream of hydraulic structures is one of the major concern in its stability analysis and operation .The excess energy existing immediately downstream of such structures has to be controlled. Hence, it is necessary to design and install a device for dissipating excess energy in order to prevent downstream scour. The drop structures is one of the commonly structures used for dissipating excess energy.In the present study an experimental approach is employed through which different types of stilling basin with different heights were tested using one drop and two consecutive drops. Moreover the effect of the end sill and baffles with different heights and different bed slopes was investigated. The hydraulic parameters involved were measured experimentally using a model of straight drop installed in the available (S6) multi-purpose flume in the fluid mechanics lab at the Civil Engineering Department, University of Garyounis.Results showed that, for one drop the presence of end sill reduced the length of the jump by a small value approximately 4%with an increase of relative energy loss by a small value. The increase of relative baffles block height increases the optimum relative height of drop (w/y1=6), and the relative energy loss .For two consecutive drops it was found that the most value of energy loss takes place in the second basin. The presences of end sill at the end of second basin increases the performance of second basin by small value approximately 5%. It is also shown that increasing the relative height of baffles blocks lead to increases in the relative energy loss (within the ranges considered in this study), and the optimum relative baffle block height hb/y1=0.77 to 1.7 and bed slope is 1/50

Published: November 2021

In this research a fuzzy neural network is proposed so, fuzzy mechanism and adaptive neuro fuzzy mechanism are designed and simulated to control the (flow rate) control action on cell multiplexing in (ATM). The cell flow rate on the output of neural- fuzzy controller. Has been simulated depending on the input variables, one of these inputs is the queuing message (message length), the second one is the number of inputs, and third is the type of massage. These input variables are used to build the fuzzy rules uses (FNN) as its condition and the control action as its consequence, combines these rules to represent the model or system. NN is used as a training algorithm to learn the weights of fuzzy system. The simulation process has been executed by using (MATLAB). In the light of this research, it is apparent that NNS and fuzzy logic based systems can play an important role in the control of cell multiplexing in (ATM) network, since they can provide adaptive model free, real time control to the user.
Behavior of Reactive Powder Concrete Columns Under Eccentric Compression Loading
Authors: Yaarub G. Abtan
Published: November 2021

The strength of concrete columns is controlled by the strength of the material and the geometry of the cross section. The use of Reactive Powder Concrete RPC technology has proven most popular with superior strength, stiffness and durability being the major advantages. An experimental investigation was carried into the behavior of RPC columns subjected to axial load with initial eccentricity. Twelve columns were prepared with 120mm square section at the midsection and were hunched at the ends to apply eccentric loading. The specimens were tested up to failure to evaluate the effects of the variation of the concrete type (normal or RPC), presence of steel fibers and longitudinal steel ratio. Experimental data on strength, lateral displacement and failure mode was obtained for each test. The comparative analysis of the experimental results showed that the use of RPC caused substantial variation in the ultimate strength and failure modes. Also, inclusion of steel fibers in RPC was an effective way to prevent spalling of the concrete cover and increase the ductility, as well as, high ratio of longitudinal reinforcement delays the buckling of the columns and increases strength.

Published: November 2021

The aim of this work is to study the effect of adding copper (C10200 AISI) foils on the welding joint of the austenitic stainless steel type (AISI 304).The austenitic stainless steel has low weldability by resistance welding where the concentrated current causing a high thermal expansion. Due to heat stored, non-complete fusion, burn throw, warp edge and distortion of weldments even when change machine settings. So to solve this problems a copper strips used as a filler metals between the stainless steel sheets, these problem disappears, because of that strip will be act as a heat sink and no burn through; but complete fusion, uniform weld

Published: November 2021

During the last few decades, the field of medical image processing has been closely related to neural network methodologies and their applications. In the present investigation a 512×512 Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) images for different region of the brain are registered to eliminate the dimensionality differences between the two images, then separated both of them by fast-fixed point algorithm after truncation of each image in to almost 1000 image patches of 15×15 dimension and transform them to 1-D and order them into row-wise fashion as well as reducing the entered data of lesser interest by Principle component analysis (PCA), finally applying the fusion process using different methods. The result shown that the differently defined brain regions can be separated using batch approaches for both CT and MRI and could be a powerful and accurate diagnostic tool, especially, for surgical and radiotherapy, planning and oncology treatment after a suitable fusion process is carried out on it.

Authors: Mohammed Z. Al-Faiz  , Mohammed S. Saleh
Published: November 2021

Uncertainty is an inherent part in controllers for real world applications. In this paper we compare the performance differences between type-1 and interval type-2 fuzzy logic (IT2FLC) controllers, with five and three term membership functions. The controllers are used to control a PM DC motor in a closed loop real time system. The performance of system with each controller to a step is recorded. The results showed that there is a statistical difference between the fuzzy logic type-1 and type-2 controllers. It is also found that a type-2 five term controller is as good as a type-1five term or type-2 three term controller

Creating Commons: Reflections on Creating Natural Resource Management Regimes in South Sulawesi, Indonesia
Authors: Batiran Karno , Sirimorok Nurhady , Verheijen Bart , Fisher Micah R. , Sahide Muhammad Alif K.
Published: November 2021

Thirteen years ago, PAYOPAYO Peasant School Network, an Indonesian community organizing network based in Sulawesi, facilitated Participatory Action Research (PAR) that eventually culminated in a creation of a common resource management regime around an irrigation system for agricultural use in Tompobulu, a village within a national park in upland South Sulawesi. This note from the field presents a reflection on collective action experiences of a community in building the commons in 2008 to 2009, and revisits the extent to which the commons has been managed, how management regimes changed over time, and how it survives as a commons today. The initial factors allowing for establishment of the commons, understood here as a social practice toward common goals, were a shared need for water (local needs & conditions), and the success to make use of the irrigation commons as a means to initiate other collective actions. Drawing from concerted engagement and analysis conducted in 2021, this note revisits the key factors and highlights different ways the commons continues to persist, namely due to the distinct benefits felt by participants, the existence of institutions that regulate the use and maintenance of the commons, the existence of a monitoring system among members, participation of members in formulating and modifying the rules, and the recognition of National Park authorities on the commons and its rules.
Design of intelligent real-time safety supervision system for pension institutions based on LBS
Authors: Song Caili , Kateb Faris , Abo Keir Mohammed Yousif
Published: November 2021

With the gradual ageing of China's population and the single-child family system becoming the backbone of society, the traditional pension way of relying on children at home not only does not guarantee the quality of life of the elderly, but also brings great pressure to the work and life of young people. The way of relying on pension institutions to provide for the aged is becoming gradually accepted by society. In elderly care institutions, safety supervision systems provide an important link to protect the safety of the elderly, thereby ensuring accurate analysis and supervision of the elderly persons’ activity routes and activity rules, and thus allowing an early warning to be given in a dangerous situation. The system realises the real-time positioning and monitoring of the elderly activity track, and can give early warning and timely rescue to the elderly who enter into any dangerous area. The system includes a server monitoring program and mobile APP; ASP.NET Technology to develop the monitoring program; SQL Server 2012 for data storage; and model view controller (MVC) architecture for the APP to improve the efficiency of program development. The supervision program comprises the functions of personnel information management, fence management, positioning service, activity track record, danger warning and rapid rescue. The APP deploys the location-based service (LBS) technology of Android, uses Baidu map API to obtain location information and draw activity track, and stores the information in the mobile phone SQLite database. The APP is installed on mobile phones, bracelets and other devices carried by the elderly and staff, which can record the current position of the person in real-time and simultaneously transmit it to the computer. When the elderly enter into a dangerous area, the system can quickly select the nearest staff and inform them for rescue, so as to ensure the safety of the elderly. After simulation test, the system has now reached the preset function.
Study of statistical damage constitutive model of layered composite rock under triaxial compression

Published: November 2021

The layered composite rock was subjected to triaxial compression tests under constant confining pressure and the stress–strain curves under different confining pressures were obtained. Based on the continuous damage theory and statistical strength theory, it is assumed that the strength of rock microelements obeys Weibull distribution by taking the defects such as random micro-cracks in the rock into account. The statistical constitutive model of layered composite rock with damage correction is established by taking the axial strain of rock as a random distribution variable of microelement strength. The model parameters were determined by the curve fitting method and referring to some test parameters. By comparing the experimental data and the constitutive model curve, the rationality and feasibility of the model are verified.
Modeling Epitaxial Layer Growth from Gas Phase for Analysis of Influence of Changing Technological Process with Variation in Growth Zone Heating
Authors: Pankratov E. L.
Published: November 2021

In this paper, we analyze the nonstationary heat transfer during growth of epitaxial layers in epitaxy reactors from the gas phase. Based on this analysis, we formulate several recommendations on organization of heating of the growth zone for increasing homogeneity of epitaxial layers. We introduce an analytical approach for analysis of heat transfer during the growth of epitaxial layers from the gas phase. The approach gives a possibility to simultaneously take into account the nonlinearity of heat transfer, as well as changes of their parameters both in space and time.
Abundance and annual distribution of freshwater snails and some trematode cercariae at Damietta Governorate, Egypt

Published: November 2021

In addition to being a good food source, freshwater snails are considered one of the positively and negatively influencing invertebrates on the environment. Several biotic and abiotic factors are thought to affect the distribution and the dynamics of these snails. Freshwater snails are the most dominant and conspicuous individuals of the freshwater biota in Damietta Governorate. In this study, freshwater snails were collected monthly from 5 geographically and environmentally different sites at Damietta Governorate at the north of Egypt during June 2017-May 2018. Seven snail species; Lanistes carinatus, Lanistes varicus, Pila wernei, Segmentorbis angustus, Melanoides tuberculata, Biomphalaria alexandrina, and Gabbiella senoriansis, were identified. Lanistes carinatus was the most abundant species (56.4%) in the collection sites. Besides, Al-Inaniyyah village had the highest snail species abundance and variety. The abundance of the most recorded species varied seasonally; the highest abundance was recorded during summer while the lowest was during winter. The abundance of some snail species correlated positively or negatively with some physico-chemical parameters; water temperature, dissolved oxygen, conductivity, total dissolved salts, and electrical conductivity. Two types of trematode cercariae; gymnocephalus cercariae and xiphidiocercariae, were harvested from Lanistes carinatus. The highest prevalence of both cercarial types was detected during summer. The correlation between the prevalence of both cercarial types and the physico-chemical parameters were determined. Xiphidiocercariae were the most predominant cercarial type in Damietta Governorate. Our findings suggest that the invasion of some freshwater snails is likely to be the cause of the low prevalence or complete absence of some medically important intermediate snail hosts. We recommend further characterization of the distribution of freshwater snails and the interrelationships among them in Egypt, and suggest a controlled use of selected snail species to combat their medically important analogues.
