In a recent paper [4], Xu studied some alternating multiple zeta values. In particular, he gave two recurrence formulas of alternating multiple zeta values $ \zeta^\star({\bar 1}, \{1\}_{m-1}, {\bar 1}) $ and $ \zeta^\star(2, \{1\}_{m-1}, {\bar 1}) $. In this paper, we will give the closed forms representations of $ \zeta^\star({\bar 1}, \{1\}_{m-1}, {\bar 1}) $ and $ \zeta^\star(2, \{1\}_{m-1}, {\bar 1}) $ in terms of single zeta values and polylogarithms.

In this work, we consider a coupled nonlinear viscoelastic Kirchhoff equations with degenerate damping, dispersion and source terms. Under suitable hypothesis, we will prove that when the initial data are large enough (in the energy point of view), the energy grows exponentially and thus so the $ L^{2(p+2)} $-norm.

A warrant is a financial agreement that gives the right but not the responsibility, to buy or sell a security at a specific price prior to expiration. Many researchers inadvertently utilize call option pricing models to price equity warrants, such as the Black Scholes model which had been found to hold many shortcomings. This paper investigates the pricing of equity warrants under a hybrid model of Heston stochastic volatility together with stochastic interest rates from Cox-Ingersoll-Ross model. This work contributes to exploration of the combined effects of stochastic volatility and stochastic interest rates on pricing equity warrants which fills the gap in the current literature. Analytical pricing formulas for hybrid equity warrants are firstly derived using partial differential equation approaches. Further, to implement the pricing formula to realistic contexts, a calibration procedure is performed using local optimization method to estimate all parameters involved. We then conducted an empirical application of our pricing formula, the Black Scholes model, and the Noreen Wolfson model against the real market data. The comparison between these models is presented along with the investigation of the models' accuracy using statistical error measurements. The outcomes revealed that our proposed model gives the best performance which highlights the crucial elements of both stochastic volatility and stochastic interest rates in valuation of equity warrants. We also examine the warrants' moneyness and found that 96.875% of the warrants are in-the-money which gives positive returns to investors. Thus, it is beneficial for warrant holders concerned in purchasing warrants to elect the best warrant with the most profitable and more benefits at a future date.
Pomenske lastnosti in značilnosti rabe slovenskih oziralnopoljubnostnih zaimkov
Authors: Gregorčič Kristina
Published: October 2021

Prispevek predstavlja osrednje pomenske lastnosti in značilnosti rabe slovenskih oziralnopoljubnostnih zaimkov (OPZ). Analiza vzorca iz korpusa Gigafida 2.0 je pokazala, da so OPZ k negativni polarnosti usmerjeni izrazi (NPI) in izrazi proste izbire (IPI). Značilnosti NPI in s tem lastnosti eksistencialnih kvantifikatorjev OPZ dobijo v pomenskem dosegu navzdol monotonih operatorjev. V okoljih, ki niso navzdol monotona, ti zaimki dobijo lastnosti IPI. Če se OPZ nahajajo izven dosega modalnih operatorjev, privzamejo lastnosti univerzalnih kvantifikatorjev in ustvarjajo učinek proste izbire. V dosegu modalnih operatorjev in v nemodalnih okoljih pa se obnašajo kot eksistencialni kvantifikatorji in izražajo dejstvo, da govorec referenta ne pozna ali se mu njegova identiteta ne zdi pomembna. OPZ lahko uvajajo tudi proste oziralne odvisnike – določne izraze, ki opisujejo množice posameznikov ali situacij. Raba tovrstnih odvisnikov je sprejemljiva le, če obstajata najmanj dva potencialna referenta, ki ustrezata opisu v odvisniku.
Réécrire le passé pour angoisser le présent
Authors: Ledroit Mathias
Published: October 2021

La « Nova Història », la « nouvelle histoire », est un courant de pseudo-histoire qui apparaît dans l’espace public en 2007. Elle se propose de révéler la spoliation et l’oppression que l’Espagne exerce sur la Catalogne depuis 1469. Cette réécriture du passé entend diffuser un sentiment d’angoisse et d’urgence dans la société catalane, urgence de proclamer l’indépendance pour rompre les chaînes de la colonisation avec lesquelles l’État espagnol a entravé les Catalans. Il ne s’agira pas, dans cet article, de rétablir les faits ni de s’interroger sur la pertinence de ce courant. On envisagera cette « nouvelle histoire » comme un système doté d’une cohérence interne et dont on proposera un premier essai de synthèse.
Uruguay: Artistas ante la nueva legislación laboral
Authors: Dominzain Susana
Published: October 2021

Este artículo presenta avances de investigación sobre la legislación cultural referida a los artistas, bajo los gobiernos del Frente Amplio, en Uruguay. Para ello se analizaron las actas de la Comisión de Cultura y la discusión parlamentaria en torno al Estatuto del Artista y Oficios Conexos aprobado en el 2008 y fueron sistematizados los datos del Ministerio de Trabajo sobre el Registro de Artistas. Ambas formas de abordar la temática nos ha permitido conocer cuántos son los artistas registrados y sus perfiles y las posiciones de algunos legisladores en la discusión parlamentaria. Los hallazgos muestran lo escasamente conocida que resulta ser esta legislación por los artistas y la sociedad. Esto dificulta y posterga nuevos logros legislativos más incluyentes.

El estudio nos permite, acercarnos a la historia de la mujer desde una perspectiva no oficial, pero también reconocer en particular, algunas de las contribuciones fundamentales que dichas artistas hicieron al Taller de Gráfica Popular, así como al arte mexicano en general..
Biopolítica, higienismo y poder: el caso del noticiero “Ecuador Noticiero Ocaña Film 1929”.
Authors: Peñalosa Xavier Puig
Published: October 2021

En los inicios de la producción propia ecuatoriana de noticias cinematográficas, Ecuador Noticiero Ocaña Film 1929 es pionera en este tipo de informativos. Apoyada y en gran medida subvencionada por el régimen de turno que vio en este tipo de imágenes una magnífica oportunidad propagandística, la que nos ocupa transmite a través de sus fotogramas una propuesta corporativa basada en el concepto hegemónico y elitista de civilización, y cuya constitución se basa en la ideología higienista. O, dicho de otra manera, se trataba de aplicar una biopolítica al cuerpo social a través, fundamentalmente, de un cierto control sobre el cuerpo humano en el que, y ampliamente comprendida, la disciplina higienista era fundamental. En ese momento, esta disciplina constituía simbólicamente y reforzaba orgánicamente el proyecto nacional y racista blanco-mestizo de las élites capitalistas y burguesas ecuatorianas.
Selective Inhibition of the Interaction between SARS-CoV-2 Spike S1 and ACE2 by SPIDAR Peptide Induces Anti-Inflammatory Therapeutic Responses
Authors: Paidi Ramesh K , Jana Malabendu , Mishra Rama K , Dutta Debashis , Pahan Kalipada
Published: October 2021

Many patients with coronavirus disease 2019 in intensive care units suffer from cytokine storm. Although anti-inflammatory therapies are available to treat the problem, very often, these treatments cause immunosuppression. Because angiotensin-converting enzyme 2 (ACE2) on host cells serves as the receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), to delineate a SARS-CoV-2–specific anti-inflammatory molecule, we designed a hexapeptide corresponding to the spike S1–interacting domain of ACE2 receptor (SPIDAR) that inhibited the expression of proinflammatory molecules in human A549 lung cells induced by pseudotyped SARS-CoV-2, but not vesicular stomatitis virus. Accordingly, wild-type (wt), but not mutated (m), SPIDAR inhibited SARS-CoV-2 spike S1–induced activation of NF-κB and expression of IL-6 and IL-1β in human lung cells. However, wtSPIDAR remained unable to reduce activation of NF-κB and expression of proinflammatory molecules in lungs cells induced by TNF-α, HIV-1 Tat, and viral dsRNA mimic polyinosinic-polycytidylic acid, indicating the specificity of the effect. The wtSPIDAR, but not mutated SPIDAR, also hindered the association between ACE2 and spike S1 of SARS-CoV-2 and inhibited the entry of pseudotyped SARS-CoV-2, but not vesicular stomatitis virus, into human ACE2-expressing human embryonic kidney 293 cells. Moreover, intranasal treatment with wtSPIDAR, but not mutated SPIDAR, inhibited lung activation of NF-κB, protected lungs, reduced fever, improved heart function, and enhanced locomotor activities in SARS-CoV-2 spike S1–intoxicated mice. Therefore, selective targeting of SARS-CoV-2 spike S1-to-ACE2 interaction by wtSPIDAR may be beneficial for coronavirus disease 2019.
Development of Neutralizing Multimeric Nanobody Constructs Directed against IL-13: From Immunization to Lead Optimization

Published: October 2021

IL-13 is a pleiotropic cytokine mainly secreted by Th2 cells. It reacts with many different types of cells involved in allergy, inflammation, and fibrosis, e.g., mastocytes, B cells, and fibroblasts. The role of IL-13 in conditions involving one or several of these phenotypes has therefore been extensively investigated. The inhibition of this cytokine in animal models for various pathologies yielded highly promising results. However, most human trials relying on anti–IL-13 conventional mAbs have failed to achieve a significant improvement of the envisaged disorders. Where some studies might have suffered from several weaknesses, the strategies themselves, such as targeting only IL-13 using conventional mAbs or employing a systemic administration, could be questioned. Nanobodies are recombinant Ag-binding fragments derived from the variable part of H chain–only Abs occurring in Camelidae. Thanks to their single-domain structure, small size (≈15 kDa), good stability, and solubility, they can be engineered into multispecific constructs for combined therapies or for use in new strategies such as formulations for local administration, e.g., pulmonary administration. In this study, we describe the generation of 38 nanobodies that can be subdivided into five CDR3 families. Nine nanobodies were found to have a good affinity profile (KD = 1–200 nM), but none were able to strongly inhibit IL-13 biological activity in vitro (IC50 > 50 µM: HEK-Blue IL-13/IL-4 cells). Multimeric constructs were therefore designed from these inhibitors and resulted in an up to 36-fold improvement in affinity and up to 300-fold enhancement of the biological activity while conserving a high specificity toward IL-13.
Ethical Aspect of Duty of Care and Resource Allocation during COVID-19 Pandemic
Authors: Biswas Sujash , Das Abhishek
Published: October 2021

Ethical practice is always considered to be a safe practice. Pandemic is one situation where the execution of ethical principles becomes a bit difficult as differences of opinion are to be taken into consideration. We have faced dilemmas previously during the AIDS outbreak or Avium Influenza pandemic. Similar ethical dilemmas if not more we are facing during the COVID-19 pandemic. Ethical concerns are mainly related to duty of care towards COVID patients, scarce resource allocation, telemedicine service, and COVID death cases. In this article, we will discuss ethical issues in relation to the duty of care and scarce resource allocation. We will also highlight guidelines to minimize ethical dilemmas and the role of the administration to make ethically correct policies as much as possible. This will not only help us to face the current pandemic but also will help to create a root map for making policies if any such pandemic hits the community in future.

Published: October 2021

Background:

The COVID-19 pandemic has forced us to adapt to new habits, and to embrace a new normal. The authors wanted to conduct a study to gauge the public perception regarding the ongoing pandemic.

Aims and Objectives:

A single center cross-sectional study was conducted among hospital employees and their dependents attending the COVID screening outpatient department at a tertiary care hospital in Northern India, to gauge the knowledge, perception, and prevalent myths among the same.

Methodology:

For a set of 14 questions, the participants had a mean (standard deviation) score of 6 (2.14). Only 50 participants had adequate knowledge in all the three sections, namely knowledge, perception, and myths.

Results:

Our observation has been that the particular group we studied were still unaware of basic information such as transmission, clinical features, use of masks, and other key aspects about the ongoing pandemic.

Conclusion:

Extensive information campaigns and behavioral changes are needed to bring up the level of knowledge, particularly in hospital employees because they make an important subgroup in the community about creating a sense of awareness about the pandemic.
Quality of Life Scale among Perimenopausal and Postmenopausal Women in a Rural Area of Delhi
Authors: Basu Saurav , Pangtey Ruchira , Banerjee Bratati , Kumar Saurabh
Published: October 2021

Background:

The average Indian woman has early onset menopause compared to the global average. Assessment of the quality of life (QOL) among Indian women with perimenopause or postmenopause at health facilities using a rapidly administered, validated instrument is required.

Objective:

To assess the QOL among perimenopause and postmenopausal women in India and to ascertain the factors influencing their QOL using a brief instrument suitable for clinical use.

Methods:

A cross-sectional study was conducted during August to October 2019 in the medical outpatient department at a government secondary care hospital in a rural area of Delhi, India. We enrolled women in the age group of 40–59 years.

Results:

We recruited 136 participants with a response rate of 92%. The mean (standard deviation) age of the participants was 49.2 (6.1) years. A majority (51.2%) of the participants were illiterate, and only 22 (16.6%) were employed. The Cronbach's alpha of the Utian QOL was 0.824, indicating good reliability. The QOL scores of the participants were below average for the occupational and emotional domains, but higher for the health and sexual domains. On bivariate analysis, we found education not more than primary school, not being employed, and having more than two children were associated with lower QOL scores.

Conclusion:

Women with greater education, employment, with up-to two children and without depressive symptoms reported a better QOL, but it did not differ significantly between perimenopausal and postmenopausal women.
Transthyretin Amyloid Cardiomyopathy
Authors: Sharma Sweety , Sharma Bhawna
Published: October 2021

Transthyretin amyloid cardiomyopathy (ATTR-CM) is potentially a fatal disease characterized by abnormal buildup of amyloid fibrils primarily in the heart causing progressive heart failure. It is categorized into two subtypes-hereditary ATTR and wild type ATTR. Previously, no treatment is available, due to which liver transplantation, multi-organ transplantation, and symptomatic treatment were the only therapies at that time. Approval of Vyndaqel (tafamidis meglumine) and Vyndamax (tafamidis) capsules in 2019, acts like a kick in the research fields due to which other therapeutics are now emerging. Several clinical trials are going on to evaluate the efficacy of different drugs in ATTR-CM. Most of the clinical trials demonstrated positive outcomes which leads to further evaluation for confirmation. In this review treatment pipeline, ongoing clinical trials and challenges related to ATTR-CM are described.
Polyvector fields and polydifferential operators associated with Lie pairs

We prove that the spaces

and

\operatorname{tot} \big(\Gamma ({\Lambda^\bullet A^\vee}) \otimes_R{{\mathcal{D}_{poly}^{\bullet}}}\big)

associated with a Lie pair

(L,A)

each carry an

L_\infty

algebra structure canonical up to an

L_\infty

isomorphism with the identity map as linear part. These two spaces serve, respectively, as replacements for the spaces of formal polyvector fields and formal polydifferential operators on the Lie pair

(L,A)

. Consequently, both

\mathbb{H}^{\bullet}_{\operatorname{CE}}(A,{\mathcal{T}_{poly}^{\bullet}})

and

\mathbb{H}^{\bullet}_{\operatorname{CE}}(A,{\mathcal{D}_{poly}^{\bullet}})

admit unique Gerstenhaber algebra structures. Our approach is based on homotopy transfer and the construction of a Fedosov dg Lie algebroid (i.e. a dg foliation on a Fedosov dg manifold).
Blind Spot Monitoring System (BSMS): Operating Characteristics and User Interface
Authors:   Advanced Driver Assistance Systems (ADAS) Committee
Published: October 2021

This document specifies the minimum recommendations for Blind Spot Monitoring System (BSMS) operational characteristics and elements of the user interface. A visual BSMS indicator is recommended.

BSMS detects and conveys to the driver via a visual indicator the presence of a target (e.g., a vehicle), adjacent to the subject vehicle in the “traditional” Adjacent Blind Spot Zone (ABSZ). The BSMS is not intended to replace the need for interior and exterior rear-view mirrors or to reduce mirror size. BSMS is only intended as a supplement to these mirrors and will not take any automatic vehicle control action to prevent possible collisions. While the BSMS will assist drivers in detecting the presence of vehicles in their ABSZ, the absence of a visual indicator will not guarantee that the driver can safely make a lane change maneuver (e.g., vehicles may be approaching rapidly outside the ABSZ area).

This document applies to original equipment and aftermarket BSMS systems for passenger vehicles. This document does not apply to installing a BSMS on either motorcycles or commercial vehicles. Finally, this document does not address Lane Change Warning systems, which monitor areas substantially farther back than the side blind spot areas monitored by the BSMS (See ISO FDIS 17387).

A cross-sectional study on mother’s knowledge, feeding practices, childcare and malnutrition in Sumbawanga, Tanzania
Authors: Protas Pessa , Mweya Clement Nyamunura
Published: October 2021

Background: Malnutrition is the major cause linked to many diseases and is a burden recognized in many developing countries including Tanzania. A child’s intake can have a significant impact on health, growth, and development. Understanding mothers’ knowledge of children’s intake can play a vital role in improving their nutritional status. This study aimed at exploring mothers’ knowledge, feeding practices, childcare, and malnutrition among children aged between six months and five years.

Methods: A hospital-based cross-sectional study was undertaken in Sumbawanga municipal, from September to December 2020. Data was collected from interviews filled in structured questionnaires among mothers of children aged six months to less than five years. Data were analyzed using SPSS version 20 based on a total of 190 study participants. Descriptive statistics and c2 tests were used to assess the significance levels of associated variables.

Results: The total sample of children included in the study was 190, therefore 190 mothers. Out of the 190 mothers, 65 (34.21%) had not attended formal education, 53 (27.89%) had a primary education level,  42 (22.11%) had a secondary education level and 30 (15.79%) has a college or university education level. The majority of mothers, 145 (51.58%) were single, divorced or widowed whereas the majority of mothers, 51.58% (98) were not employed. Marital status and education level had an impact on child’s care and malnutrition reported cases (c2 = 15.06, p < 0.0001). Food availability in families of many children with more individuals living together showed to be significantly associated with incidences related to malnutrition (χ2 = 25.76, p < 0.001). Mother’s feeding practices of less than two times a day showed to be significantly associated with and incidences related to malnutrition (χ2 = 23.54, p < 0.0001). Mother’s good maternal care showed to be significantly associated with attendance to ANC services and husband/ partner's financial support (χ2 = 43.22, p < 0.001).

Conclusion: Current mothers’ knowledge and practices about malnutrition and incidences of nutritional related-illness in children in Sumbawanga municipal calls for urgent health education to improve children’s health status.
Early clinical markers of metabolic syndrome among secondary school adolescents in Dar es Salaam, Tanzania
Authors: LWABUKUNA WARLES CHARLES , MGONDA YASSIN
Published: October 2021

Background: Metabolic syndrome is defined by the presence of three of four disorders; hypertension, obesity, dyslipidemia, and diabetes mellitus type 2. The presence of anyone or two of these constitutes early markers of the syndrome. It occurs in children and adolescents but its magnitude has not been determined consistently in many countries including Tanzania.  Detection of early clinical markers is an effective preventive strategy. The aim of this study was to determine the prevalence of early clinical markers of metabolic syndrome among secondary school adolescents in Dar es Salaam.

Methods: A descriptive cross-sectional study was conducted among secondary schools in   Dar es Salaam. Structured questionnaires were used to record demographic data. Blood pressure and anthropometric measurements were taken using standard methods. Fasting blood samples were collected for blood glucose, total cholesterol, low-density lipoprotein, high-density lipoprotein, and triglyceride. The International Diabetes Federation (IDF) criteria were utilized.

Results: A total of 217 adolescents were enrolled; of these males and females were 32% (69) and 68% (148) respectively. Of these; 75% (162) were young adolescents (14-17years). Participants from public and private schools were 48% (104) and 52% (113) respectively. Early clinical markers of metabolic syndrome were detected in 43% (94) with at least one clinical marker and 9% (19) with two markers. The prevalence of full-blown metabolic syndrome was 1.4% (3). Overall, the clinical markers included; dyslipidemia 30% (64), central obesity 22% (48), hyperglycemia 13% (29) and hypertension 2% (4). The prevalence of central obesity was 26% (42) among young adolescents and 11% (6) among elderly adolescents and the difference was significant (p value= 0.02).

Conclusion: Early clinical markers of metabolic syndrome exist among Dar es Salaam secondary school adolescents with dyslipidemia being the commonest marker while central obesity was much common among young adolescents. School programs for screening students for detection of early markers of metabolic syndrome are needed.

Background: Human Immunodeficiency Virus (HIV) infection among children is mainly vectored through mother-to-child transmission. Prevention of mother-to-child-transmission strategy is highly effective; however, its accessibility and utilization is affected by the lack of knowledge among other factors.

Methods: A cross-sectional study was conducted among antenatal care attendees in two districts in Tanzania to determine their knowledge and utilization of the prevention of MTCT services.

Results:  We interviewed 160 antenatal care attendees aged 18-45 years with a mean (SD) age of 30.4 (6.3) years; 74 (46.2 %) were HIV-infected. HIV-infected women demonstrated significantly correct knowledge of HIV (p=0.001) and AIDS (p=0.014) than uninfected individuals. HIV-infected women also significantly demonstrated correct knowledge of mother-to-child transmission during pregnancy than HIV-uninfected women (p=0.016) and during delivery (p=0.005). A significant proportion of HIV-positive women compared to HIV-negative women were aware that correct use of antiretroviral during pregnancy can reduce the risk of mother-to-child-transmission of HIV (p<0.039), but only 6 (3.75%) of all women were aware that correct use of antiretroviral during delivery can significantly reduce the risk of mother-to-child-transmission. HIV-infected women had significant comprehensive knowledge of HIV/AIDS (p=0.001) and prevention of mother-to-child transmission of HIV (p=0.006) than HIV-negative women. Comprehensive knowledge prevention of mother-to-child transmission of HIV was low among the study participants. Male partners’ involvement in maternal antenatal care was significantly higher among HIV-infected women than males from the HIV-infected women group (p<0.006).

Conclusion: The study demonstrated inadequate knowledge of PMTCT among women who made ANC visits. HIV uninfected women had poorer knowledge compared to the HIV-infected ones. Routine HIV counseling and testing services were highly accepted among these women.

Authors: Díaz-Sánchez Jorge , García-González Mercedes Caridad , Lorente-González Gustavo Yasser , Cardoso-Paneque Lianet
Published: October 2021

El queso procesado o fundido se ha convertido en una buena alternativa para las industrias lácteas, debido a que tiene un período de vida útil prolongado y presenta mejor facilidad de manejo en las empresas. El objetivo de la investigación fue establecer una proporción adecuada de sales fundentes que permita alcanzar la textura requerida en el queso fundido untable, mediante una mezcla de sales de bifosfato y monocitrato de sodio. La investigación fue realizada mediante un diseño de mezcla Simplex-Lattice con dos componentes (monocitrato sódico y bifosfato sódico) y tres variables respuestas (pH, humedad y textura), para la cual se llevaron a cabo 15 corridas experimentales. Los resultados obtenidos en la variable pH indicaron buena correlación ya que los valores son elevados, las variables humedad y textura mostraron que no existe correlación con respecto a las sales. Se obtuvieron valores de humedad de 59,36 a 65,69 % y la textura de 11,86 a 20,0 siendo la media de los valores de textura caracterizados como bueno. Atendiendo a los resultados alcanzados en la optimización múltiple se obtuvo que la mejor formulación de sales fundentes para queso fundido untable es: 70 % de bifosfato de sodio y 30 % de monocitrato de sodio, o emplear el 3 % de la mezcla solo con bifosfato de sodio ya que ambas formulaciones ofrecen como resultado la textura deseada.

Palabras claves: queso fundido untable, sales fundentes, sales de bifosfato y monocitrato de sodio.

Several facilities can be rented out to the public at the agency, such as halls, dormitories, and guest houses. There are still many people who do not know this public facility that can be used. The rental process is still done manually by coming directly or sending a letter of application. In terms of bookkeeping, sometimes there are some data recording errors. Therefore, a website was developed that can help provide information on what public facilities can be used for the public and used to carry out the rental process to help the community make rentals without having to come directly to BP PAUD and Dikmas. Developing this website using the Waterfall software development methodology has stages, namely Requirements Definition, which is done by making Flowcharts. System and Software Design is carried out by making Data Flow Diagrams (DFD) and Entity Relationship Diagrams (ERD), Implementation and Unit Testing with the programming languages used, namely HTML, PHP, CSS, Bootstrap, Javascript and MySQL and Integration and System Testing. The testing method used is the Blackbox method. Based on the test results, it can be concluded that this website can run according to its function.

Considerando a distribuição da espécie Phrynops geoffroanus (Schweigger, 1812) facilmente encontrada, foram capturados 20 espécimes com a utilização de armadilhas do tipo espera iscada, posteriormente foram depositados na coleção de História Natural da Universidade do Piauí (CNHNUFPI 0007 - 0026). O presente trabalho objetivou estabelecer razões alométricas entre a maturidade e crescimento do plastrão e carapaça, as medidas foram submetidas ao coeficiente de Pearson, quando os valores foram superiores (r= 0,80) submetemos à regressão univariada linear para o plastrão e exponencial para a carapaça, realizando 6 combinações possíveis. O valor de r ajustado ao coeficiente de determinação, quando igual ou superior a 0,80, consideramos a correlação forte positiva, dessa forma apresentando variáveis dependentes, as análises morfométricas indicaram a existência de correlação inferior a 0,80 apenas nas combinações CLCxLLC (r=0,7191) e LLCxCP (r=0,7364). Por meio da correlação de Pearson e o ajuste a equação linear e exponencial é possível utilizar a função para prever medidas das placas, tamanho, proporção e a dependência de crescimento entre as porções da carapaça ou plastrão na população amostral de Phrynops geoffroanus, estas predições foram confirmadas pelo teste de aderência χ2.
