Evaluating friction angles for clays: piezocone tests compared with Atterberg limits
Authors: Ouyang Zhongkun , Mayne Paul W.
Published: January 2023

A limit plasticity solution for evaluating the effective stress friction angle in clays from piezocone tests was assessed and compared with the popular notion of using laboratory Atterberg limits on remoulded specimens. The results showed that the in situ piezocone-based method provided a far more accurate and robust interpretation of the friction angle values of 155 separate clays than empirical correlations with plasticity index when compared with laboratory benchmark values obtained from triaxial compression tests. For illustration, the piezocone-based method was shown successfully to capture the effective stress parameter of four clays with friction angles of 20–37°: normally consolidated kaolin clay in chamber tests; natural soft clay deposit located at Bothkennar, UK; Troll offshore clay in the North Sea; and soft plastic lacustrine deposits in Bogota, Colombia.
Model of the mediating effect of team pride in the relationship between transformational leadership and sports activity loyalty
Authors: Oh Youngtaek , Yang Myung-Hwan
Published: January 2023

Objective: Athletes participate in sports with affection and attachment. Although the dependence of people's perception of sports activity loyalty on environmental factors has been investigated, the relationship between sports activity loyalty's psycho-sociological variables is not yet well-understood. The current study aims to test the relationships among transformational leadership, pride, and sports activity loyalty perceived by Taekwondo athletes. Methods: Transformational leadership, pride, and sports activity loyalty were measured in 263 college Taekwondo athletes who participated in the 29th National University Taekwondo Individual Championships in 2022. SPSS 23.0, PROCESS Macro (V.2.13), and Amos 23.0 programs were used for data analysis. Results: Transformational leadership exerted a positive influence on sports activity loyalty in Taekwondo athletes and a positive influence on authentic pride; however, it decreased hubristic pride. Authentic pride exerted a positive influence on sports activity loyalty but had no effect on hubristic pride. By verifying the mediating effect based on the direct effect, it was proven that transformational leadership was a factor which positively affected sports activity loyalty by mediating authentic pride. Conclusions: The results of this study imply that it is necessary to strengthen sports activity loyalty by respecting athletes’ opinions, enhancing their autonomy, and improving their authentic pride of the athletes by demonstrating transformational leadership in the Taekwondo community to perceive the athletes’ sports activity loyalty.
Technoparticipation: Scrapbooks, stories and secrets
Authors: Campbell Lee
Published: January 2023

In 1993, aged 15, I discovered Dymaxion Chronofile, architect Buckminster Fuller's very large scrapbook which he documented his life every 15 minutes from 1920 to 1983. Around the same time, my art teacher at secondary school suggested that I keep a scrapbook of images, This reflective account explores how I have worked with imagery of pages from that very large scrapbook  I kept when I was a teenager in the 1990s for just over five years – my personal private archived of images that in many ways helped to shape my understanding of (gay) male desire at a time when I felt too uncomfortable to come out as gay. The account begins with a poem I have written reflecting upon my motivations around the scrapbook and about the sociocultural context and time which it was produced in; 1990s homophobic suburban Britain. Fast forwarding from the early 1990s to 2021, the account then explains how I returned to my scrapbook as a source of inspiration for creating a poetry film as part of a body of work excavating my personal archive as an artist of over 25 years. The account then discusses how I made use of my scrapbook poetry film as part of Technoparticipation - an ongoing practice-as-research project that explores how technology becomes an additional performer/participant. In other words, how technology participates.
How do headphone checks impact perception data?
Authors: Sanker Chelsea
Published: January 2023

Headphone checks have rapidly become an assumed part of best practices in online perception studies.  Do they actually improve our ability to find phonological patterns?  They are an indirect way of trying to ensure clear audio for all participants; it is not clear that controlling for this aspect of the participants' listening setup will necessarily decrease overall variation or produce better results.  This study attempts to replicate three perceptual effects that depend on different aspects of the acoustic signal, testing whether excluding participants based on two headphone checks (Huggins pitch perception, Milne et al 2021; dichotic loudness perception, Woods et al 2017) makes the results clearer.  The Huggins check improves results for how spectral tilt influences duration perception, but no other results were improved by either headphone check.
Going to a Wandala town
Authors: FRAJZYNGIER Zygmunt
Published: January 2023

The study demonstrates that some elements of culture may be reflected in the grammatical structure of the language. The demonstration is drawn from the coding of directionality of movement in Wandala, a Central Chadic language. In this language, movement to or from a town inhabited by Wandala people is coded in a different way than movement to or from a town not inhabited by speakers of Wandala. It is as if speakers of English were using a different form for the concept of going to New York from the concept of going to Paris.This highly idiosyncratic phenomenon may have a well-motivated explanation.

Le plat consommé par l’allogène à Maroua présente parfois des ingrédients qui ne relèvent pas de sa culture. Mais le fait de consommer ces repas constitue déjà une mise en relation des éléments culturels, tant il est vrai que l’art culinaire participe de la définition d’une culture donnée. En fonction des perspectives imagologiques de Daniel-Henri Pageaux, la présente communication cherche à montrer que l’adoption des plats d’origine nordiste participe de la rencontre des cultures entre population allogène et autochtone.

Aplicación de una metodología de PBL y clase inversa al laboratorio de asignaturas en ingeniería Mecánica
Authors: Gómez-del Río Teresa
Published: January 2023

Elasticity and Strength of Materials is an elementary discipline across many engineering degrees. Students perceive it as very difficult and abstract and students’ active participation in the learning process is needed, due to its complexity and importance during the whole degree years. Hence, the main difficulty in teaching them is maintaining students' motivation and keeping their participation in the learning process. This is the reason to use new tools, such as problem-based learning (PBL) and flipped classroom, to help students understand and study the subject. In this work, we present the application of a problem-based learning to the lab in the Mechanical engineering degree, in of one the most time-consuming and difficult subjects of its program. Moreover, to enhance students’ enthusiasm and motivation, these sessions included an innovative manufacturing technology, 3D printing, and digital image correlation (DIC). Before each practical session, the students are encouraged to watch an online video with the fundamental aspects. In order to assess the success of this laboratory course, after finishing the lab sessions, the students answered a non-formal quantitative survey. The results showed that the proposed project-based learning had the ability to help integrating the knowledge and improve the skills included in the main competences. Although these results are encouraging, there are still parts of the lab activity that should be improve in order to make the activity less time consuming and the most difficult part being easier for the students.
Análisis de la acción del globo en pádel masculino y femenino profesional: estudio piloto
Authors: Sánchez-Alcaraz Bernardino Javier , Ramón Llin Jesús , González Ruben , Martínez Gallego Rafael , Sánchez Pay Alejandro
Published: January 2023

El globo en pádel adquiere una relevancia muy importante, al tratarse del tipo de golpe más utilizado para ganar la red, siendo a su vez esta acción sinónimo de éxito en este deporte, ya que el 80% de los puntos los gana la pareja que se encuentra en esa posición. Por ello, el objetivo de este estudio fue analizar el golpe de globo en pádel profesional mediante una serie de variables de eficacia, para determinar en qué situaciones de juego es más oportuno realizar este golpe. Se analizaron un total de 296 globos correspondientes a 2 partidos (final masculina y final femenina) del torneo Master Final de Madrid del circuito oficial World Padel Tour 2021. Se evaluaron los golpes de globo realizados por los 8 jugadores finalistas del torneo (4 hombres y 4 mujeres). Los resultados del estudio mostraron que en el pádel femenino se realiza un porcentaje significativamente mayor de globos que en el pádel masculino. Por otra parte, el tipo de golpe con el que se realizan más globos son los golpes directos con bote y los golpes de paredes de fondo, encontrando además diferencias entre géneros, ya que los hombres realizan un porcentaje mayor de globos de volea, mientras que las mujeres ejecutan un número mayor de globos con doble pared. Con respecto al lado de ejecución, se observó que se realiza un 10% más de globos por el lado dominante (derecha) que por el lado no dominante (revés), siendo la trayectoria paralela un 10% superior frente a la cruzada. En relación con la zona de la pista, podemos decir que las mujeres realizan casi un 30% más de globos desde el fondo de la pista, mientras que los hombres hacen un 20% más de globos desde la red. En cuanto a la eficacia de los globos, encontramos que un 64,6% no superó a los rivales, un 28,3% sí lo hizo, y un 6,7% fueron errores. Por último, se observó que más del 70% de los globos se realizan en puntos no clave.

Transferencia y pulsión: ejes de la clínica analítica
Authors: Rosero García Luis Carlos
Published: January 2023

El presente artículo toma como punto de partida el trabajo de Jacques Lacan (1964), en el cual pretende ubicar los ejes fundamentales de la clínica analítica, y para tal efecto elige dos de ellos, como son la transferencia y la pulsión, al considerar que representan hilos conductores de lo que pasa por la dialéctica inconsciente del analista y el analizante, y a la vez determinan la posición subjetiva de uno y otro. Para tal efecto, ingresa en la reflexión teórica iniciada por Freud sobre tales conceptos y se sumerge en otros referentes propios de la filosofía y la antropología.

Nuevos datos sobre patrones funerarios en el cañón del río Cauca al noroccidente de Colombia
Authors: Botero Arcila Silvia Helena , Patricia Muñoz Diana , Ortiz Cano Alejandro
Published: January 2023

A pesar de la intensa actividad de guaquería ejercida en las primeras décadas del siglo pasado en la zona norte del cañón del río Cauca antioqueño, el programa de arqueología preventiva, adelantado en el marco del Plan de Manejo Ambiental ejecutado en la construcción de la Hidroeléctrica Ituango, identificó diversas pautas de enterramiento funerario utilizados por los grupos humanos que habitaron la región en los diferentes momentos de ocupación prehispánica. Entierros primarios sellados con piedras y tumbas de cancel para entierros secundarios se identificaron para los primeros siglos de la era cristiana y tumbas tipo dolmen que estarían probablemente asociadas al periodo comprendido entre el siglo ix y el xv d. C.

Published: January 2023

La técnica de la deriva ha sido y es utilizada en investigaciones de distintas disciplinas, que comparten el interés por lo urbano. Pero aún así, como técnica de investigación psicosocial es poco usada. Una de sus principales características —potenciar que el investigador forme parte del movimiento y del ritmo de la ciudad, junto con la flexibilidad que ofrece, de incorporar lo que acontece de manera inesperada en el espacio urbano— hace que resulte ser una técnica especialmente adecuada en el contexto actual de la sociedad y sus ciudades, que están permanentemente en tránsito, atravesada por flujos y en constante transformación.
Prácticas funerarias prehispánicas como expresiones territoriales en el Porce Medio (Antioquia, Colombia) durante el periodo de los desarrollos regionales de los siglos i a xiv d. C.

Published: January 2023

Resumen. Los enterramientos humanos en el Porce Medio, nordeste del departamento de Antioquia (Colombia), en el periodo denominado desarrollos regionales, son expresiones de la manera como los grupos humanos concebían la muerte. Asimismo, el ritual funerario que incluye la construccióny localización de la tumba en el paisaje es una expresión cultural que legitima la territorialidad de los grupos locales, basada en el hecho de que allí mismo habitan los antepasados.Abstract. Human burials in “El Porce Medio”, in the period called “regional developments” are expressions of the way human groups used to conceive death, but especially, the funeral ritual that includes the construction and location of the tomb in the landscape, it is a cultural expression that legitimizes the territoriality of the local groups, based on an ancient legacy, because in such territory is where their ancestors inhabit.

Haciendo etnología con los caboclos de Quirino: la situación etnográfica como una tríada
Authors: Pacheco de Oliveira João
Published: January 2023

Resumen. El artículo acomete una revisión crítica de los viajes etnográficos que el etnólogo alemán Curt Unkel —Nimuendaju, según el nombre que le fue adjudicado por los indígenas— realizó a las aldeas ticuna de la selva amazónica brasilera. Se examinan fuentes primarias que documentan lo acontecido en esas experiencias, enmarcado ello en una reflexión sobre el ejercicio etnográfico, el cual debe ser comprendido a partir de las interacciones complejas que lo constituyen y que con creces superan la clásica dualidad investigador-investigado. En el caso de Nimuendaju, su aproximación a lo indígena se vio atravesada por los intereses, valoraciones y perspectivas del Estado o de los jefes de la explotación cauchera, estos últimos convencidos de que la selva no estaba habitada por “indios” sino por “caboclos” que pertenecían a algún barracón. Abstract. The article attempts a critical review of the ethnographic journeys of the German ethnologist, Curt Unkel —Nimuendaju, the name the indigenous peoples attached to him—, among the Tikuna of the Brazilian Amazonian jungle. The article examines primary sources that document the objectives of these experiences, framing them in a reflection regarding the ethnographic exercise which should be understood from the complex interactions that comprise it and from which we should transcend the classic duality investigator/investigated. In the case of Nimuendaju, his approximation to the indigenous question was crossed with state and rubber baron interests, values, and perspectives, the latter of whom were convinced that the jungle was not inhabited by “indios” rather “caboclos” that belonged to algún barracón.

Resumen. La orfebrería Quimbaya Clásica o Quimbaya Temprana de Antioquia y el Cauca medio en épocas prehispánicas se distingue por las formas realistas y escultóricas de mujeres con rasgos femeninos exagerados y de frutos de calabazos, calabazas y totumas; el brillo intenso y color rojizo de las superficies, y el uso de la tumbaga. El texto indaga acerca del significado subyacente a estos símbolos asociados a los grupos de poder, a partir del análisis iconográfico de la orfebrería y de la cerámica Marrón Inciso con la cual se asocia; de fuentes etnológicas y etnohistóricas, y de los estudios de simbolismo del brillo, los colores y las aleaciones de tumbaga por especialistas en estas materias. Se concluye sobre temas del pensamiento simbólico sagrado que legitimó el poder de las elites: fecundidad, fertilidad, vida, principios femeninos, renacimiento y transformación.Abstract. The Quimbaya Classic or Early Quimbaya goldwork style of Antioquia and The Middle Cauca Region in Pre-Columbian times, characterizes by its realistic and sculptural forms of women with exaggerated feminine features, and of gourds, squashes and totumas; the intense brilliance and reddish color of its surfaces; and the use of tumbaga, the gold and copper alloy. The text searches for the underlying meaning of these symbols from the iconographic analysis of the goldwork and its associated Incised Brownware ceramic style; from ethnological and ethnohistorical sources, and from studies of the symbolism of brilliance, colors and tumbaga alloys by experts in these subjects. It concludes about topics of the sacred symbolic knowledge that legitimized the power of the elites: fecundity, fertility, life, feminine properties, rebirth and transformation.
Patología dental de los antiguos residentes de Alto del Rey (El Tambo, Cauca), suroeste de Colombia (ca. 1200-1600 d. C.)
Authors: Delgado-Burbano Miguel Eduardo
Published: January 2023

Resumen. El estudio de las enfermedades dentales en grupos humanos antiguos busca reconstruir y recrear la forma de vida de las poblaciones antiguas relacionadas directamente con su estado de salud y enfermedad. Con este estudio se pretende conocer la prevalencia de las enfermedades dentales presentes en esta población, así como sus causas y su posible relación con la dieta. Para ello se analizó una muestra de 48 individuos del sitio arqueológico Alto del Rey (Cauca, ca. 1200-1600 d. C.). Se analizaron 260 piezas dentales, 44 in situ y 216 aisladas. Para este estudio se siguió secuencialmente el lavado y clasificación de las piezas dentales, análisis tafonómico, estimación del número de individuos enterrados, estimación de la edad y del sexo, así como el respectivo registro, diagnóstico e interpretación de las condiciones patológicas. Se presentó una considerable prevalencia de enfermedades como la caries (39,5%), hipoplasia (37,5%) y cálculo dental (43,7%). Por otro lado la dilaceración y la enfermedad periodontal presentaron baja prevalencia (18,7 y 8,3% respectivamente). La dieta de este grupo posiblemente fue rica en carbohidratos y particularmente en alimentos de origen vegetal, moderadamente duros y fibrosos. El alto consumo de alimentos vegetales al igual que su precaria salud oral fueron los principales causantes de algunas enfermedades como caries y cálculo dental. El conjunto de evidencias arqueológicas y paleopatológicas sugieren un tipo de sociedad con un sistema de subsistencia basado en la agricultura.Abstract. The study of dental diseases in ancient human populations seeks to reconstruct and recreate the way of life of ancient populations, these dynamics are directly related to the health-disease state. It also seeks to know the prevalence of present diseases, their causes, and possible relationship with the food habits. In order to do so, a sample of 48 individuals from Alto del Rey was analysed (Cauca, ca. 1200-1600 d.C.). 260 dental pieces, 44 in situ as well as 216 isolate were used. The washing and classification of dental pieces, taphonomic analysis, number of individuals buried, age and sex estimation as well as register, diagnosis and interpretation of pathological conditions were analysed. The results show a moderate-high prevalence of dental diseases such as caries (39,5%), hypoplasia (37,5%) and calculus (43,7%). On other hand dilacerations and periodontal disease show low prevalence (18,7%)and (8,3%). Carbohydrates as well as hard and fibrous vegetables basically composed the diet of this human group. The high vegetable consumption was as well as their precarious dental health were the main cause of some diseases as caries and dental calculus. The paleopathological and archaeological evidences show a complex society with a subsistence pattern based on agriculture.
“No do couro da onça”. Reflexiones sobre la transformación y la metamorfosis en las tierras bajas de Sudamérica
Authors: Prinz Ulrike
Published: January 2023

Resumen. La experiencia de transformación espiritual y corporal está presente en toda cultura, sin embargo, en las sociedades amazónicas se diferencia en sus connotaciones de la de las sociedades occidentales. En lugar de la metamorfosis como un proceso que transcurre linealmente, la transformación amazónica parece como un principio paradójico, similar a una disolución de límites. En el texto se abordan diversos principios de transformación a partir del concepto de “ropa” del chamán, que se diferencia del uso de máscaras y parece en sí mismo como expresión de una disolución de límites y un cambio de perspectivas.Abstract. Experiences of corporal and spiritual transformation are present in every cultural system. The notions of occidental and amazonian connotations of transformations however are very different. Instead of the metamorphosis as a linear process, amazonian transformations seem to be a paradox principle. This article tries to trace the different principles of transformations along with the concept of “clothes” of the shaman, which differs from the use of masks and in itself seems to come close to an expression of dissolution of frontiers and perspectives.Zusammenfassung.

Pressure vessel leakage detection method based on online acoustic emission signals
Authors: Zhengjie Liu , Weilei Mu , Hao Ning , Mengmeng Wu , Guijie Liu
Published: January 2023

Pressure vessel leakages cannot initially be visited directly and will gradually cause deterioration, which can result in catastrophic damage. Acoustic emission (AE) signals generated by leakage have the potential of being used for online monitoring. Unfortunately, AE signals have the
characteristics of being non-stationary, wide-band and with strong noise interference, which causes the monitoring results to have low reliability. To address the poor robustness of traditional time-domain and time-frequency domain-based monitoring methods, an online monitoring method based
on adaptive singular value decomposition (ASVD) is proposed in this paper. Firstly, singular value decomposition (SVD) is used to divide the signal space into a signal subspace and a noise subspace. Experiments indicate that SVD can distinguish leakages under conditions of different pressures
and variable temperature, which means that SVD is sensitive to changes in signal. Subsequently, update iteration-based ASVD algorithms are proposed for long-term online health monitoring and ASVD is shown to be successful in distinguishing the different statuses of intact, leakage and repaired.
To improve the robustness of ASVD, a novel energy indicator is proposed, which can identify the status change more effectively. With the proposed methodology, an online monitoring application for pressure vessel leakage detection is expected to be achievable.

A local magnitude scale is developed for Tanzania, East Africa, using data collected by the 1994/1995 Tanzania Broadband Seismic Experiment. The waveform data from 1189 local and regional earthquakes located within East Africa were corrected for instrument response and convolved with the nominal Wood-Anderson torsion seismograph response appropriate for the original definition of local magnitude. A total of 24,710 maximum S-wave amplitudes were incorporated into an iterative regression for individual event local magnitudes, 38 horizontal component station factors, and 2 linear distance-dependent factors in the log A0 term of the equation for ML. The resulting distance correction, log A0, is given by -log A0 = 0.776 log(r/17) + 0.000902(r − 17) + 2.0, where r is hypocentral distance in kilometers. This distance correction yields much less ground-motion attenuation than observed for southern California and is similar to that observed for local S waves and regional Lg waves propagating in eastern North America. Normalizing the distance correction using the standard constraint of 1-mm ground motion at 100 km for a magnitude 3.0 earthquake results in a bias of nearly half of a magnitude unit between mb and ML, with ML being larger. Normalizing using the constraint of 10 mm of motion at 17 km for ML 3.0 removes the bias in magnitude measures and indicates that structure within Tanzania is relatively high Q. The seismicity rate of Tanzania for 1994/1995 was examined using the Gutenberg-Richter seismicity distribution and is seen to follow the relation log N = 4.63 − 0.84 ML, where N is the number of earthquakes per year of local magnitude ML or greater. The catalog of events used in this study is seen to be complete to magnitude 2 to 2.5.
An indication of time-dependent seismic behavior—An assessment of paleoseismic evidence from the Arava Fault, Israel

We discuss the implications of 56 kyr of paleoseismic data from a fault on the southern segment of the Arava Fault system in Israel. At least nine events are evident, beginning 37 ka. We study in detail the frequency-magnitude relation for the fault and develop a Bayesian analysis to compare the characteristic earthquake (CE) model and the Gutenberg-Richter (GR) model. Our analysis leads to the conclusion that there was a change in seismic behavior at about 14 ka. From ∼37 ka to ∼14 ka, the seismic activity is best described by the CE model. From ∼14 ka to the present, there is no strong indication favoring one model over the other; the earthquake record is somewhat more consistent with the classical GR equation than with the CE model. If one does assume that the CE model is appropriate for the younger episode, then there is evidence of a change in the characteristic magnitude. Thus, there is evidence of a change in earthquake behavior on the fault segment ∼14 ka.
Source parameters of injection-induced microearthquakes at 9 km depth at the KTB Deep Drilling site, Germany

A fluid injection-induced seismicity experiment was undertaken in the KTB (German Continental Deep Drilling Program) main borehole at 9 km depth. Several hundred microearthquakes were recorded by a three-component geophone at 4 km depth in the pilot hole of the KTB about 200 m west of the main hole. More than 100 of these events were also recorded with good signal-to-noise ratio by a 73-element temporary network at the surface.

Several different clusters of microearthquakes with distinct waveforms were defined. Compound fault-plane solutions for the two most prominent clusters of seismic events were determined: a strike-slip mechanism for cluster 1 at an average depth of about 8.9 km and a strike-slip/reverse mechanism for cluster 4 (with the “main” ML = 1.2 event) at an average depth of 8.6 km. For both fault-plane solutions, the P axis is subhorizontal and oriented NNW-SSE, similar to the N160°E direction of maximum horizontal stress observed in the well bore. Both clusters were analyzed using an empirical Green's function method to derive the relative source time function (RSTF). Azimuthal variations of the RSTF were used to determine rupture directions and velocities. By combining the information about rupture directions with fault-plane solutions, it was possible to identify the active fault planes (NE striking nodal planes) for both clusters. Although injection-induced events are supposed to exhibit a dilatational component due to the tensile character of the source, the moment tensor inversion for both microearthquake clusters resulted in a double-couple contribution of about 90% and P axes similar to the direction of maximum horizontal stress observed in the borehole. The isotropic components of the moment tensors are insignificant due to the size of the location uncertainties.

From records of the sensor at 4 km depth, we found seismic moments of the microearthquakes ranging from 107 to 1011 N-m. The spectra were corrected for Q [Q(f) = 420 f0.5 for P, and Q(f) = 230 f0.5 for S-waves, which were determined assuming an ω2 model]. Following Brune (1970, 1971), we found source radii between 12 and 28 m and stress drops between 0.01 and 6 MPa. The average ratio of S- to P-wave energy was determined as 14.2. Our relation between seismic moment and ML is log M0 = 1.01 ML + 9.68, and between energy and seismic moment, log E = 2.0 log M0 - 15.35. These seismic scaling relations suggest that stress drop increases with seismic moment for this data set. However, it cannot be precluded that our data, covering only somewhat more than three orders of magnitude, fall in a larger trend of constant-stress-drop scaling over many orders of magnitude due to the large scatter observed over several orders of magnitude.

Background: Premature ovarian failure (POF), is menopause occurring before the age of 40, affecting 1-3% of women worldwide. The risk of POF increases with altered immunological parameters such as FAS and FASL genes, which play a fundamental role in embryogenesis and cellular homeostasis.
Objective: The study aimed to investigate the potential role of FAS and FASL genes in POF pathogenesis.
Materials and Methods: In this case-control study, the polymorphisms of FAS-670A/G and FASLIVS2nt_124A/G apoptotic genes were analyzed in 51 Iranian women suffering from POF, and 61 healthy controls. Isolation of DNA was done using the salting-out method, and genotypic analysis was performed for all the subjects using the polymerase chain reaction-restriction fragment length polymorphism method.
Results: Our results revealed that homozygous FAS-670A/A and G/G, and heterozygous FAS-670A/G are not significantly different between cases and controls (p = 0.99). Also, in different genotyping models of FASIVS2nt_124, polymorphisms were not related to POF risk (p = 0.23).
Conclusion: There is no statistical association between these polymorphisms and POF risk in women referred to genetic counseling clinics.
Key words: FAS, FASL, Polymorphism, Premature ovarian failure.
