Authors: Elsen Renold , Deepa Jenitha
Published: February 2023

Safety is a major concern addressed in various industries and most specifically in transportation industries. Road accidents are undoubtedly more frequent and are responsible for many permanent disabilities deaths worldwide. Many works have been done to improve the safety of different vehicles as the number of accidents is increasing. The main objective of this work is to further improve road safety by providing instantaneous warnings to drivers about hazards in their intended path in hilly region. This further it aims to provide a pleasant and peaceful hill travel and to avoid any possibility of accidents in hill curves. The roads in these hilly regions are always filled with many hectic and endless curves. These curves are classified into Hair-Pin Curves, Salient Curves and Re-entrant Curves. These curves offers partial or no visibility about the incoming traffic for the drivers. In this approach two ultrasonic sensors are used to obtain the velocity and the distance of the object placed in the curves. The signals from the two sensors are obtained, compared and the probability of the vehicles reaching the curves is predicted using a simple algorithm with the help of Arduino UNO module. Then the warning signals are provided to the lamps and thus the drivers can be alerted by this approach the accidents can be avoided effectively.

Car hydraulic brakes are important safety components for passengers and are thus the good condition of brakes are essential for braking. By using the vibrational signatures, the state of the brake components can be determined. In this proposed study, electronic condition monitoring is suggested as a possible solution to such issues by using a machine learning method with a piezo-electric transducer and a dynamic data acquisition system. Ford EcoSport setup was used to acquire the vibration signals for both good and bad braking conditions. The mathematical Descriptive statistical features from the vibration signals were obtained and the feature selection has been done with the C4.5 decision tree classifier. The appropriate number of features needed to classify a particular problem is not determined by a specific method. A thorough study is, therefore, necessary to find the right number of features. The fault analysis of the Ford EcoSport hydraulic braking system has been established through the use of the C4.5 decision tree classifier and logistic model tree (LMT) classifier.

The enormous need of effective transportation creates an unavoidable situation in automobile industries to improve and maintain safety systems in vehicles. In crisis, brake disc of the braking system plays a vital role in effective braking of the vehicle. The main objective of this proposed study is to design a disc with two different groove patterns and a material with two different compositions. By using solidworks, a brake disc with proper slots and groove pattern (J hook and square groove) was designed for improved bite, debris, clearance, reduced distortion / vibration and effective heat transfer through convection process. In which two different materials namely zinc based Aluminium Alloy (AA8011) and its composite (AA8011 (5 wt% B4C +3 wt% Gr)) are considered after heat treatment (T6) as disc materials. The properties are measured and given as input data set in ansys workbench for further processing. The thermal transient analyses are done under loaded condition for the proposed disc. In addition, the static structural analysis is performed to study the deformation and von mises stress. Thus by taking this study the examined brake disc was identified to have effective strength and braking performance. Also, we recommend the usage of the hybrid composite disc brake with j groove for real time usage in student formula vehicles.

Published: February 2023

The search for a new renewable biofuel and aiming to make the environment clean is always a challenge for a researcher in developing a sustainable fuel for future mobility. In this context, vegetable oils were found as good alternative biofuels for diesel engines as they are biodegradable and renewable in nature. Most of the physio-chemical properties of vegetable oils are very closer to diesel. However, pure vegetable oils are expensive and using them to operate the diesel engine may affect the food supply chain. In view of this limitation, Waste Cooking Oil Biodiesel (WCOB) derived from waste cooking oil (WCO) was found to be very attractive solution for the above said constraints as they are easily available, renewable, economically and environmentally viable. This research aims at studying the effect of hybrid nano additives (i.e. Copper Oxide with Zinc Oxide) on performance and emission characteristics of a diesel engine fueled with Waste Cooking Oil Biodiesel. The Copper oxide with Zinc oxide hybrid nano fluids were prepared by a novel wet chemical method. These nano fluids were prepared in two mass fractions (i.e. 50ppm and 100ppm) and blended with WCOB and considered as test fuels such as WCOBCZ50 and WCOBCZ100. The stability of hybrid nano fluids prepared by wet chemical method and blended with WCOB was found good. The fuels diesel, WCOB, WCOBCZ50 and WCOBCZ100 were tested in the test engine at different loading conditions to evaluate the engine performance and emission parameters. The experimental results revealed that the addition of hybrid nano additives in WCOB improved the fuel properties which were reflected in terms of increased brake thermal efficiency and reduced brake specific fuel consumption compared to neat WCOB. It was also observed that HC, CO, NOx and smoke emissions were reduced with the addition of hybrid nano additives as compared to neat WCOB. Thus, it can be concluded that inclusion of hybrid nano additives pave way for effective utilization of WCOB in an unmodified diesel engine over a period of time.
Electromagnetic Radiation Analysis of Permanent Magnet Synchronous
Motor in Electric Vehicles under Different Driving Conditions
Authors: Chen Luhao , Xu Zhaoping , Liu Liang
Published: February 2023

The electromagnetic compatibility problem of the permanent magnet synchronous
motor (PMSM) has become increasingly prominent with its continuous development
to high power and high torque. To solve this problem, this paper adopts a method
based on the establishment of body structure and windings of the PMSM to analyze
its electromagnetic radiation (EMR). The radiation stimulus source is acquired
by establishing the control model of the PMSM drive system under different
driving conditions in Simulink and Carsim. The EMR model of the whole vehicle is
established in FEKO by creating winding models and importing three-dimensional
(3D) mesh models of the vehicle body and PMSM. The field circuit co-simulation
and transmission line method are used in this paper. Finally, we can obtain the
electric field radiation strength at different detection points under different
driving conditions. The simulation results correspond with the EMR theory and
electromagnetic shielding theory. It plays a leading role in the EMR analysis of
the PMSM drive system in an electric vehicle.
Simulation Study on Position Control Strategy of a Three-Phase
Permanent Magnet Synchronous Motor for Steer-By-Wire Application
Authors: Twishime Alexis , Xu Zhaoping , Wu Chao , Liu Liang , Zhao Liao
Published: February 2023

Vehicle intelligence with more precision and reliable steering mechanism for
safety, comfort, and energy-saving is the recent key technology in the
automobile industry. Due to its merits, the permanent magnet synchronous motor
(PMSM) has been utilized in automation industries to serve as the servo system
and is introduced in the vehicle field as the engine for the steering system. To
avoid the complexity of computing and the current coupling effect of vector
control which is easily affected by motor parameters changes, and to ensure that
the steer-by-wire motor precisely tracks position, this paper adopts the sliding
mode direct torque control method and proportional feedforward integrated with
the fuzzy-proportional integral (PI) controller to address this issue. The
proposed method is simulated and used to analyze the PMSM uncertainties changes
due to the road condition and ensure the steer-by-wire motor tracking precision.
The vehicle model is established in CarSim and combined with the simulated model
under double-lane shift and step angle signal scenarios to verify the precision
and steadiness of the steer-by-wire system. The steering resistance moment is
considered as the load for the steering actuator due to the road condition, and
the load observer is studied to mitigate the loading effect on the actuating
motor. The results demonstrate that the following curve angle under the proposed
method coincides highly with the reference signal with no fluctuation, and the
tracking position accuracy is improved by 78.3% compared to the traditional
proportional integral derivative (PID) controller. Moreover, through the
realistic design of the steer-by-wire system control strategy, the vehicle
handling stability is realized, which is beneficial to relieve driving fatigue
and improving steering efficiency.
Expansion of the Operating Range of a Multi-fuel Single-Disk Rotary
Engine Using a 2+2-Spark Plug Combustion Process
Authors: Gotthard Thomas , Hofmann Peter , Zahradnik Felix
Published: February 2023

Unmanned, autonomous aerial vehicle applications are an indispensable part of
modern aviation. The propulsion of such aerial vehicles is often realized by
Wankel rotary engine. They are particularly suitable for this application due to
their high power-to-weight ratio and smooth operation. As a result of their
properties and geometric characteristics, Wankel rotary engines are usually
operated with highly volatile fuels like aviation gasoline (AvGas). In
comparison, the existing aviation refueling infrastructure is oriented toward
the most common aviation fuel, kerosene. This and other reasons, such as
significantly lower prices and easier fire protection regulations, lead to the
desire to be able to operate these propulsion units with kerosene. Opposed to
reciprocating engines, the low compression ratio of rotary engines prevents the
implementation of compression ignition (CI) combustion processes. In previous
studies, the effects of an air-assisted injection system on operation with
different fuels were examined on the basis of a spark-ignited combustion
process. Operation with kerosene in particular requires appropriate mixture
preparation in order to be able to ensure a stable combustion process over a
wide operating range. The purpose of this paper is to investigate improvements
for further optimization of the combustion process with regard to efficiency,
stability, and power output based on the findings of the previous
investigations. One of the most promising steps is a combustion process with the
ignition of four spark plugs (2+2). Based on simulative investigations using
computational fluid dynamics (CFD), a potential analysis regarding the optimal
positioning of the additional spark plugs and the effects on the combustion
process is carried out. It could be shown that a correspondingly “early”
positioning of the trailing spark plugs should be aimed at. Based on the
simulated results, the preferred spark plug configuration is implemented on the
real engine. Subsequently, the influence of the use of four spark plugs on the
combustion process is examined on the basis of experimental investigations. In
particular, the effects on the possible operating range in kerosene operation
are investigated in more detail.

He studied at the Hart Conway Chicago School of Elocution while working as an engineer for the family business, Weyburn (sic) Machinery Co. There, he was trained in military drills and in ‘harmonic Gymnastics’, by a second-generation Delsarte teacher: Ida Simpson-Serven. He worked in vaudeville as a pianist, while developing dance acts with integrated lighting effects. Moving to New York, he gained a reputation with Feature Acts. Among his 300+ dance direction and stage direction credits are three groups of shows to which he brought innovations: plotted musical comedies with Lew Fields for and about contemporary 1911–14 businessman audiences, topical revues, especially with Florenz Ziegfeld, Jr., and roof garden revues. He was equally famous for developing individual specialties for performers in vaudeville and on Broadway. Wayburn ran a New York studio and Home-Study Course, which he advertised as delivering ‘Health, Beauty and Independence’ to prospective women students. In the 1920s, he added radio production and training and was experimenting with television revues just before his death in 1942.
Art Cinema
Authors: Hamblin Sarah
Published: February 2023

Although the term circulates widely in popular and academic discourse, ‘art cinema’ is a notoriously difficult concept to define, conjuring a wide range of associations and assumptions concerning the aesthetics and politics of film practice. At its most basic level, the term is typically used to denote feature-length narratives structured according to a specific set of aesthetic codes that position them in opposition to mainstream films. In this sense, art cinema exists somewhere between commercial and avant-garde cinema, foregoing the tight causal logic of the former in favour of techniques that emphasise stylistic expression, ambiguity, and self-reflexivity, while still remaining within the general sphere of narrative cinema. The term is typically used to signify films—usually made outside the major studios—in which the personal artistic vision of the director takes precedence over narrative intelligibility and marketability. Alongside these formal traits, art cinema is identified through a specific exhibition environment (independent art house theatres, film festivals, and college campuses) that similarly differentiates it from commercial cinema. These non-mainstream qualities, coupled with the challenging nature of the films themselves, have resulted in the common association of art cinema with ‘high art,’ as a body of quality films for a more sophisticated and discerning audience.
Schneemann, Carolee (1939–)
Authors: Levin Erica
Published: February 2023

Carolee Schneemann is an American artist (born in Pennsylvania, United States) whose work interrogates vision as embodied experience. She has produced films made to be screened in conventional theatrical contexts, and has also innovated the use of filmic and video-graphic elements in collage environments and happening-like performances. Schneemann is known within the larger context of post-war art for incorporating her own body into works of performance such as Eye/Body (1963), Meat Joy (1964), Interior Scroll (1975), and Up To And Including Her Limits (1973–1976). Trained as a painter, she embraced film as a means of radically expanding the medium beyond the canvas. Her process is rooted in the dynamic relation between perception and visibility, particularly as it concerns the body’s legibility within a social matrix of power and difference. In her film Fuses (1967), she works against conventional cinematic codes of eroticism while exploring her sexual relationship with composer James Tenney. The work, a densely layered collage, records moments of lovemaking and everyday life over the course of a year. Schneemann emphasises the haptic and tactile qualities of vision by baking, stamping, and exposing the film to natural elements, drawing an analogy between the materiality of bodies on screen and the celluloid substance of the film itself.

José Carlos Mariátegui was the most influential Latin American Marxist of the twentieth century. From 1914 to 1920 he worked as a journalist in Lima, Peru. Persecuted by the government, he travelled to Europe in 1920, where he studied Marxism in depth as a result of contact with socialist artists and intellectuals. In 1923 he returned to Peru persuaded of the importance of implementing socialism in the country. However, rather than following a European pattern, he developed a national variant of socialism that combined Marx’s ideas with the communal collectivism of indigenous culture.

Jacques Maritain was a leader among those who attempted to update and transform Catholic teaching for the modern world. Born to a Protestant republican, he converted to Catholicism alongside his wife in 1906. At the time, French Catholicism was a profoundly conservative force, and Maritain was closely involved with Charles Maurras and the monarchist, anti-Semitic Action française. Maritain was above all a revitalizer of the Thomist tradition, and in these early years he interpreted Thomas in support of the agnostic Maurras. After 1926, when the Vatican condemned Maurras, Maritain embarked on his own course. As described in The Primacy of the Spiritual (1927), Maritain now argued that Aquinas counselled a strict separation between the political and spiritual realms.

Brooker, Bertram (1888–1955)
Authors: Betts G.
Published: February 2023

Novelist, painter, and public intellectual, Bertram Brooker (1888–1955) was a leading force in the modernizing of Canadian culture in the early twentieth century. Brooker believed that the rapid advances in technology and commerce associated with modernity had fundamentally changed the nature of Western civilization. Consequently, artists, whom he believed to be the most sensitive to broad social modifications, had a moral, indeed spiritual, mandate to respond to these changes. Furthermore, it was his hope that artists, especially Canadian artists, could seize the opportunity of the great opening and speeding up of society to surpass the various binaries that structured the Western imagination (such as body/mind, good/evil) for something more holistically integrated. The spiritual nature of his thinking was influenced by the popular mysticism of the Theosophical Society, though he was not himself a member, and by the materialist mysticism of John Middleton Murry, P D. Ouspensky, and Richard Maurice Bucke, each of whom advanced an evolutionary model of human consciousness.
Dreyer, Carl Theodor (1889–1968)
Authors: Oveisy Fouad
Published: February 2023

Carl Theodor Dreyer was a journalist, theatre critic, scriptwriter and film director born and brought up in Copenhagen. It is difficult to speak of a narratological or stylistic consistency throughout Dreyer’s oeuvre, particularly in regard to his late films, which comprise the bulk of his canon. Nevertheless, in their acute concern with aesthetic self-reflection, his late films have acquired the title of minor early modernist masterpieces (Schamus 2008, 3). The films feature aporetic narrative logic, circular and/or tableau mise-en-scène, and nonlinear/disruptive treatment of cinematic space and time. Dreyer is also renowned for his meticulous approach to filmmaking, distinguishing him as one of the first auteurs of cinema. It is a well-established fact that Renée Jeanne Falconetti, the actress of The Passion of Joan of Arc (1928), suffered from a mental breakdown at the completion of the film’s shooting due to the excessive demands and constraints put on her acting by Dreyer.
Lasker-Schüler, Else (1868–1945)
Authors: Liska Vivian
Published: February 2023

Else Lasker-Schüler can be regarded as the most important German female modernist and is one of the few women affiliated with the Expressionist movement. Her work—mainly poetry, poetic prose and several plays—has often been situated by its critics and readers in a realm not of this world and outside historical time, in a sphere of eternal poetic truth, a realm oblivious of the cultural, political, and social realities of her day. Although her eccentric and exalted poetic imagination indeed seemingly escapes her immediate environment into fairytale fantasies peopled by princes and princesses, sheiks and magicians, angels and tricksters, such a description of her work misses its importance as an artistic as well as existential endeavour of creative innovation in which a return to age-old religious, literary, cultural and textual traditions meets a radically modernist idea of poetry and selfhood.

Levin, Hanoch is an Israeli playwright and short story writer. Born in the southern quarters of Tel Aviv to lower middle-class Polish immigrants Levin’s background has provided the inspiration for many of his plays and stories. Until the advent of Levin’s unique voice Israeli drama had been devoted almost entirely to the reality of life in the country. Levin’s work scorned all the accepted social dogma and resisted all ideology, while still referring to the Jewish diaspora past and life in present-day Israel. His plays can be divided loosely into three categories: satire, usually in the form of cabarets, grotesque domestic comedies, and elaborate dramas presenting universal messages based on myth, biblical stories and world literature.

Yeshurun, Avot (1904–1992)
Authors: Lachman Lilach
Published: February 2023

Avot Yeshurun was a renowned Hebrew poet who remained split between two cities throughout his life: his childhood village Krasnistav and the city of Tel-Aviv, where he lived until his death. Born on Yom Kippur, 1904, in Neskhyzh in the Ukraine, Yechiel Perlmutter (his original name) grew up in Poland. At the end of the First World War , he experienced displacements and exiles, and by 1925 arrived in what was then Palestine. After the Second World War, he discovered that his whole family had been destroyed, and his world collapsed: ‘Hebrew literature will set the prayer’, he said, alluding not only to the breakage the Jewish people underwent but to the disaster that left its mark on the twentieth century and threw the entire lyrical tradition into question. The story of his name change (in 1948) from Yechiel Perlmutter to the Hebrew name Avot Yeshurun (literally: ‘the fathers will see’, but the poet paraphrased it as ‘for the fathers mirror in us’) is retold in his poetry and prose as a narrative of abandonment and betrayal, endowing him both with a subjectivity that is incomparable in Israeli modernism and with the authoritative speech of the witness.

Saadi Yousef is an Iraqi poet, author, journalist, and political activist. He has published 45 volumes of poetry, nine books of prose, several essays and has translated various literary works into Arabic. Yousef’s socialist sympathies and opposition to Saddam Hussein’s regime forced him to leave Iraq in 1979 and live in exile in a range of countries before settling in London in 1999. Often referred to as one of the most influential figures in modern Arabic poetry, he was a key proponent of the twentieth-century movement away from traditional Arabic poetics. Yousef’s poetry is distinctive in its use of free verse and its attention to personal experiences of political realities. Although his poetry reflects upon the turbulent conditions in Iraq, it also engages with a range of wider socio-political contexts in the Arab World.

The Conversion of Polish-Lithuanian Tatars from Islam to Christianity in the Nineteenth Century. A Typology and an Effort to Evaluate the Phenomenon
Authors: Konopacki Artur
Published: February 2023

This article is an attempt to present the problem of abandoning the Muslim religion in favor of Christianity. The article is based on materials collected and stored in the archives of Russia (Saint Petersburg), Lithuania (Vilnius), and Belarus (Grodno). These mostly contain either surviving records of baptisms sent to the consistory or police reports. The cases of conversion among nineteenth-century Muslims in the territory of the Russian Empire cited in the article have served as the basis for this phenomenon’s typology in the Muslim Tatar community. Moreover, they have provided the basis for analyzing whether it is possible to fit them into pre-existing conversion models in social sciences. The examples quoted in the text show the kinds of life problems that prompted Muslim Tatars to abandon the religion of their ancestors, e.g., terminal illness, the issue of marriage, or the likelihood of rejection by one’s group. It should be mentioned that there had already been conversions among Muslim Tatars in the early period of their settlement. However, this trend has never taken on a mass character, as evidenced by the relatively good condition of the Muslim community living in the former territories of the Grand Duchy of Lithuania in the twentieth and twenty-first centuries.

The Ritual Places of Contemporary Pagans in Kraków

In the following article I describe ritual places used by four Kraków Neopagan groups (Native Polish Church, Group Mir, Free Rodnovers of Kraków, and Reformed Druids of Gaia Poland). The most important locations include the surroundings of Krakus Mound (along with the Liban quarry below and the ‘sacred circle’ on the opposite site of the quarry) and Grove by the Wilga river. The used sites and their context are analysed, as well as the reasons why a particular place was chosen. I focus on the perspective of my interviewees, using Kim Knott’s spatial analysis and the combination of the three approaches by Belden C. Lane. Based on participant observation and semi-structured interviews with members of the studied groups, I distinguish three categories of reasons (physical; connected to culture and tradition; metaphysical), which show the multidimensional character of the decisions made and many perspectives in which ritual places are perceived.

In 2021, Garner showed that this representation can be established in terms of algebraic theory and comodels: the set of infinite streams $A^{\mathbb{N}}$ is the final comodel of the algebraic theory of $A$-valued input $\mathbb{T}_A$ and the set of stream processors $\mathit{Top}(A^{\mathbb{N}},B^{\mathbb{N}})$ can be seen as the final $\mathbb{T}_A$-$\mathbb{T}_B$-bimodel. In this paper, we generalize Garner's results to the case of free algebraic theories.

Revisiting Decidable Bounded Quantification, via Dinaturality
Authors: Laird James
Published: February 2023

We use a semantic interpretation to investigate the problem of defining an expressive but decidable type system with bounded quantification. Typechecking in the widely studied System Fsub is undecidable thanks to an undecidable subtyping relation, for which the culprit is the rule for subtyping bounded quantification. Weaker versions of this rule, allowing decidable subtyping, have been proposed. One of the resulting type systems (Kernel Fsub) lacks expressiveness, another (System Fsubtop) lacks the minimal typing property and thus has no evident typechecking algorithm. We consider these rules as defining distinct forms of bounded quantification, one for interpreting type variable abstraction, and the other for type instantiation. By giving a semantic interpretation for both in terms of unbounded quantification, using the dinaturality of type instantiation with respect to subsumption, we show that they can coexist within a single type system. This does have the minimal typing property and thus a simple typechecking procedure. We consider the fragments of this unified type system over types which contain only one form of bounded quantifier. One of these is equivalent to Kernel Fsub, while the other can type strictly more terms than System Fsubtop but the same set of beta-normal terms. We show decidability of typechecking for this fragment, and thus for System Fsubtop typechecking of beta-normal terms.

A Complete Diagrammatic Calculus for Boolean Satisfiability
Authors: Gu Tao , Piedeleu Robin , Zanasi Fabio
Published: February 2023

We propose a calculus of string diagrams to reason about satisfiability of Boolean formulas, and prove it to be sound and complete. We then showcase our calculus in a few case studies. First, we consider SAT-solving. Second, we consider Horn clauses, which leads us to a new decision method for propositional logic programs equivalence under Herbrand model semantics.
Free Commutative Monoids in Homotopy Type Theory
Authors: Choudhury Vikraman , Fiore Marcelo
Published: February 2023

We develop a constructive theory of finite multisets in Homotopy Type Theory, defining them as free commutative monoids. After recalling basic structural properties of the free commutative-monoid construction, we formalise and establish the categorical universal property of two, necessarily equivalent, algebraic presentations of free commutative monoids using 1-HITs. These presentations correspond to two different equational theories invariably including commutation axioms. In this setting, we prove important structural combinatorial properties of finite multisets. These properties are established in full generality without assuming decidable equality on the carrier set. As an application, we present a constructive formalisation of the relational model of classical linear logic and its differential structure. This leads to constructively establishing that free commutative monoids are conical refinement monoids. Thereon we obtain a characterisation of the equality type of finite multisets and a new presentation of the free commutative-monoid construction as a set-quotient of the list construction. These developments crucially rely on the commutation relation of creation/annihilation operators associated with the free commutative-monoid construction seen as a combinatorial Fock space.

Bi-invariance for Uniform Strategies on Event Structures
Authors: Paquet Hugo
Published: February 2023

A recurring problem in game semantics is to enforce uniformity in strategies. Informally, a strategy is uniform when the Player's behaviour does not depend on the particular indexing of moves chosen by the Opponent. In game semantics, uniformity is used to define a resource modality !, that can be exploited for the semantics of programming languages. In this paper we give a new account of uniformity for strategies on event structures. This work is inspired by an older idea due to Melli\`es, that uniformity should be expressed as "bi-invariance" with respect to two interacting group actions. We explore the algebraic foundations of bi-invariance, adapt this idea to the language of event structures and define a general notion of uniform strategy in this context. Finally we revisit an existing approach to uniformity, and show how this arises as a special case of our constructions.

Women in organised crime groups: A social network approach
Authors: Guerreiro Ana , Sousa Pedro , Gomes Silvia
Published: February 2023

Organised crime groups are traditionally understood as being composed of men, with a rigid hierarchical structure and well-divided tasks. However, recent studies have been showing that criminal networks (horizontal structure) are increasingly common and even an alternative to the typical rigid structure in organized crime, which allows for a more flexible, dynamic, and adaptive criminal group. Moreover, women are progressively present in such groups, especially in drug trafficking groups, and, in some cases, play relevant roles inside those criminal organisations. In this study, criminal court files related to trafficking organised crime groups involving one hundred defendants were analysed by applying criminal network analyses techniques. The objective was to examine the participation and centrality of women in the functioning of the drug trafficking groups. The findings show that women have a significant presence within these networks, play important roles inside the criminal networks and enjoy of high centrality positions, being some of them decisive key players in the functioning of the group.
Judicialización de los casos de violencia de género y construcción del sentido de justicia: factores y agentes institucionales intervinientes
Authors: Zuloaga Lojo Lohitzune , Alemán salcedo Eliana
Published: February 2023

A partir del análisis de 540 casos tramitados en el juzgado de violencia contra la mujer del partido judicial de Pamplona en 2017 y de la verificación de relaciones estadísticamente significativas entre 56 variables, este artículo problematiza aquellos elementos que suelen considerarse para explicar los procesos de victimización. Se evidencia que el lugar de los hechos y la declaración de la víctima inciden en que un procedimiento llegue a juicio, dadas las dificultades del sistema para probar los hechos. Desde un enfoque de género y sociológico, se concluye que las características de la víctima adquieren importancia si influyen en su decisión de declarar. Se observa que además de los motivos extrajudiciales de la víctima, las interacciones con autoridades y sus decisiones afectan a su sentido de justicia. También que haya o no enjuiciamiento resulta crucial en su proceso de victimización y en el reconocimiento de su victimidad.
Genotypes and Associated Risk Levels of Human Papilloma Virus among Female Patients Attending Rabuor Sub County Hospital, Kisumu
Authors: Okwaro Irene Adhiambo , Onguru Daniel , Ogolla Sidney , Odongo Esther
Published: February 2023

Background: Human papillomavirus is the main factor in the etiology of cervical cancer, with over 99.7% of cases being associated with high-risk human papillomavirus infection. Although the majority of HPV infections are asymptomatic and self-limiting, persistent HPV infection can result in genital warts, oropharyngeal cancer, and cervical cancer in women, in addition to various anogenital malignancies and other genital warts in both men and women. Method: This was a cross-sectional descriptive study which employed a convenience sampling technique where both qualitative and quantitative methods were used for data collection. A total of 374 participants were enrolled in the study and a semi structured questionnaire was administered to collect socio-demographic, reproductive and sexual history data. Laboratory analysis involved detection of HPV DNA hybrids with a chemiluminescent substrate, Digene Hybrid Capture 2 technology. Descriptive and inferential (logistic regression) analyses at level of significant (α=0.05) were used to summarize the data, and results illustrated using charts and tables. Results: The study findings reported a significant risk level of human papillomavirus among female of age group 40-49 years (AOR; 0.15, 95% CI: 0.03-0.79; p = 0.026). Furthermore, in bivariate logistic regression the circulating HPV genotypes among the respondents was significantly characterized among women of the same age group (95% CI; 0.09-0.7; p = 0.008) as well as in the multivariate regression (AOR = 0.13; 95% CI: 0.02-0.72; p = 0.019). Conclusion: The study thus concluded that there is 23/94 (25.67%) risk of developing cervical cancer due to high risk level HPV (with the presence of low risk level HPV 71/94 (74.33%) known for causing various forms of warts. Therefore, there is need for combined efforts from the Ministry of health and stakeholders to avail and train health care workers on the usage of HPV DNA kits to ensure timely detection of low and high-risk levels HPV. This will ensure timely identification of women at increased risk for the development of cervical cancer, thereby reducing mortality rate.

Published: February 2023

If someone is liking pigeons as pets, this may be due to their intelligent, effortless, and loving nature. The chief objectives of this study were to relate pigeon lovers as a pet with the level of glucose in their urine. Around 100 students of Bahauddin Zakariya University Multan Pakistan were participants of this study. Pee has glucose that is measured for measuring the glucose in urine. If glucose is not present in the urine it shows the kidney is working well. There is no major effect of glucose in urine with the love of a pigeon as a pet.

O sentido das paixões e emoções: Cícero e os estoicos
Authors: ROMERO FREDERICO
Published: February 2023

Este artigo apresenta uma revisão bibliográfica crítica sobre as particularidades da ética estoica descrita por Cícero em sua análise das paixões. As principais palavras utilizadas pelos estoicos derivam-se do grego páthe (paixões), que Cícero traduziu para o latim como perturbationes (perturbações). Os estoicos definem as paixões como movimentos contrários à natureza e desviados da razão correta; como julgamentos cognitivos equivocados de valor sobre quais os verdadeiros bens a serem perseguidos pelo ser humano, de modo que deveriam ser eliminadas (apátheia) na busca final pela virtude e felicidade. Nesse sentido, Cícero descreve 32 espécies de paixões definidas e detalhadas pelos estoicos, correlacionando-as e diferenciando-as das definições apresentadas por seus principais adversários.
A religião na sociedade democrática segundo John Rawls
Authors: TARCIZIO HENTZ JOSÉ
Published: February 2023

O artigo apresenta a proposta de John Rawls para o problema da compatibilidade da religião na política. A resposta indicada por esta filosofia política ultrapassa a ideia meramente exclusivista ou inclusivista das ideias religiosas por acentuar o domínio político em torno da razão prática, garantindo, assim, a convivência das ideias plurais na razão pública. A objetividade do debate proposto aos cidadãos na esfera pública possibilita o diálogo político de todos com todos.
