2D Seismic Structural Study of the Area Between Halfaya, Noor and Amara Oil Fields, Southeastern Iraq
Authors: Al-Azzawi Bakr Samar , Ali Kamal K.
Published: July 2024

The study area is located in the Missan government in southeastern Iraq, including oilfields (Halfaya, Noor, and Amara). The study area is about 966 Km2. Based on the 2D seismic reflection interpretation, well-logs data (sonic and estimated density logs), and synthetic seismogram of well Am-2, two horizons were identified and picked (Nahr Umr and Shuaiba) within the Lower Cretaceous age. For the picked reflectors, two-way time and depth maps were created to display the subsurface's structural makeup. The structural interpretation shows two structural axes in the study area. The first is the Halfaya-Amara axis, whose direction is WNW-ESE corresponding with the Amara structure. This axis deviates southeast due to the tectonic effect at the Halfaya structure. Another tectonic force affected the Halfaya structure in the northwest-southeast direction leading to the appearance of a branch of a convex extension towards the north from the middle of the Halfaya structure, completing this branch to a structural closure as nose towards the Noor structure in the northern part of the study area. The second axis of Halfaya-Noor oilfields trending northwest-southeast direction.
A hybrid The Dwarf Mongoose Optimization Algorithm with Nelder- Mead method and its application for allocation reliability
Authors: Fadhil Roaa aziz , Hassan Zahir Abdul Haddi
Published: July 2024

The Dwarf Mongoose Optimization Algorithm (DMO) is inspired by the behaviour of Dwarf Mongoose which can strike the ideal balance throughout research between exploration and exploitation. In this article, we combine algorithms of the Dwarf Mongoose Optimization Algorithm and the Nelder-Mead Algorithm (DMONM). In addition, the statistically evaluated functions is utilized by calculating the average and the standard deviation values that are used to validate the suggested algorithm's performance. The experimental results are on high-efficiency optimization functions with various dimensions. The hybrid algorithm produces good, encouraging, and better outcomes than the original algorithms. The results show that the proposed algorithm could enhance the effects of DMO when it used to solve the optimization issues of the multi-objective reliability system

Synthesis, Identification, and Biological Activity Investigation of New Pyrazolines Derived from Vanillin
Authors: Ali Raniah T. , Dawood Rafid S.
Published: July 2024

This work includes the synthesis of new pyrazoline derivatives 6-20 over two steps. The first step included a condensation between vanillin and various aromatic ketones (acetophenone, p-nitroacetophenone, p-chloroacetophenone, p-bromoacetophenone, and 2-acetylnaphthalene) to provide the corresponding chalcone derivatives 1-5 in high yields (up to 93%). The second step involved a reaction of 1-5 with hydrazine hydrate, phenyl hydrazine, and p-nitrophenyl hydrazine, which gave the desired products 6-20 in yields ranging from 60 to 85%. The structures of the prepared compounds were confirmed by FT-IR and 1H NMR spectroscopy. A few of the produced compounds were tested for antibacterial and antioxidant properties.
Evaluation of the Impacts of Pesticides Exposure in Different Durations on the Neural System and Antioxidants in Iraqi Farmers
Authors: Abdulsalam Haneen , Azeez Maan Abdul , Jouda Jamela
Published: July 2024

The objective of this research was to investigate the effects of pesticides in different durations on some neurotransmitters and oxidative parameters compared to controls. A total of 120 male farmers participated in this study, 30 not exposed to pesticides served as control group and 90 exposed to pesticides and were split into two groups based on their exposure durations (˂5 & ≥5 years) and three age-groups (˂20, 20-40 and ≥41 years). Blood was collected to determine acetylcholinesterase (ACHE), serotonin (5-TH), dopamine (DA), reactive oxygen species (ROS), total antioxidant capacity (TAC) and malondialdehyde (MDA) levels using ELISA kits. The results of ACHE, serotonin, dopamine and TAC levels increased, whereas MDA and ROS levels decreased among farmers exposed to the pesticides. According to the exposure duration and farmers age, only 5-TH, DA and TAC levels were affected. It can be concluded that pesticides exposure may have an acute effect on acetylcholine and a chronic effect on the serotonin and dopamine via change in the antioxidant system which may play an important role in the neural diseases.

Published: July 2024

The development of anticancer drugs remains a formidable challenge. Poterioochromonas malhamensis, known for its predatory nature on microbes and plankton, was investigated for anticancer properties. This study screened and quantified phytochemicals using LC-MS and evaluated the anticancer effects of aqueous ethanol extracts of P. malhamensis from Tavanampalli's freshwater bodies. Phytochemical analysis by HR-LCMS detected proteins, phenols, flavonoids, and alkaloids. The extract contained 87.75 mg of quercetin equivalents, 134.55 mg of gallic acid equivalents, and 72.64 mg of bovine serum albumin equivalents per gram of dry weight. LC-MS also identified amino acids, fatty acids, amides, and esters in the extract. Antiproliferative activity was assessed using MTT assay, AO/ETBR, and Annexin V/Propidium iodide (PI) staining assays. The extract exhibited IC50 values of 95.09 µg, 103.63 µg, 162.14 µg, 339.30 µg, and 355.18 µg with A375, HepG2, HeLa, HT29, and A549 cell lines, respectively, outperforming cisplatin, which had IC50 values of 3.56 µg, 4.87 µg, 3.88 µg, 7.23 µg, and 4.65 µg. This study is the first to report the antiproliferative activity of P. malhamensis, broadening the scope of research in anticancer compound discovery.

Authors: Andrade Cornejo Camila , Flores Sánchez Gustavo Geovanni , Coronel-Pangol Katherine
Published: July 2024

La pandemia mundial producto del COVID-19 ocasionó importantes pérdidas económicas y financieras en el sector bancario ecuatoriano. El objetivo del presente estudio es determinar en qué medida el riesgo crediticio y la liquidez afectan la rentabilidad de las mutualistas en Ecuador, entre el 2018 y 2021. Para tal efecto, la población estuvo constituida por las cuatro mutualistas existentes, con cuyos datos se trabajó con datos de panel de 192 observaciones, aplicando un modelo PLS-SEM para evidenciar las relaciones. De esta manera, los resultados mostraron que el riesgo crediticio incide negativamente sobre la liquidez y la rentabilidad de estas instituciones financieras; en el caso de la liquidez, se ha podido percibir que esta no afecta a la rentabilidad. En consecuencia, es sumamente importante controlar el riesgo crediticio, a través de los índices de morosidad, por lo que es necesario considerar la estructura de cartera.

Este estudio examina conversaciones con posturas de usuarios de X en México acerca de los productos comestibles ultraprocesados, recientemente asociados con obesidad. Se identificaron publicaciones en 2019 y 2020 a través de hashtags en temáticas denominadas "etiquetado", "ultraprocesados" y "comida chatarra". Se utiliza un enfoque mixto para identificar patrones de palabras y desarrollar un análisis basado en la teoría de redes sociales. Se encontraron 211,585 tweets y 904,484 retweets de 90,828 y 321,637 cuentas, respectivamente. Hubo un énfasis en las conversaciones durante procesos legislativos, destacando el hashtag #etiquetadoclaroya. Las interacciones más intensas ocurrieron en las discusiones sobre un nuevo etiquetado de advertencia. Los perfiles más influyentes pertenecían a medios de comunicación, academia y sociedad civil. La participación de la industria alimentaria fue limitada, por lo que su papel en el debate no es concluyente. Este método puede usarse en otros países para monitorear la discusión de regulaciones o políticas.

Authors: Isaza Carolina , Manrique León Alberto
Published: July 2024

Durante 18 meses en la Clínica de Dismorfología del Hospital Universitario del Valle, Cali, Colombia, como parte del grupo multidisciplinario de la Clínica de Labio y Paladar Hendido, se presentó la oportunidad de revisar 100 pacientes. Se encontró que la fisura facial más común era el labio hendido con o sin paladar hendido; la prevalencia fue mayor en hombres que en mujeres. De todos los pacientes con hendiduras orales, 39% tenían otras anomalías o síndromes asociados. Entre los más frecuentes se observaron: síndrome de van der Woude, trisomía 13, displasias frontonasal y otros. Los hallazgos anteriores sugieren que el labio y paladar hendidos no son siempre una entidad aislada, sino que se pueden asociar con otro tipo de malformaciones que comprometen sobre todo la cara y los miembros.

Authors: Jiménez Rafael , Martínez Mayder , Peñalver Ronoel
Published: July 2024

Background: Zinc is a trace element with a great importance for both intrauterine and postnatal growth of infant with growth retardation. Objective: To assess the effect of zinc sulphate supplementation on the growth and psychomotor development in a cohort of infant with low birth weight during their first year. Patients and methods: A double blind longitudinal study of a cohort of 163 infants was carried out. Infants were randomly assigned into two groups, the supplemented group with 87 infants received a dose of 10 mg/day of zinc sulphate solution during 6 months and the non supplemented group with 76 infants received a dose of 10 ml/day of physiologic solution without zinc in the same period. Results: The increased weight is positively related to zinc supplementation as is evidenced by the weight gain graph and the repeated measures of analysis, whereas, the height variable is not influenced in the same way. In relation to the psychomotor variables, the motor developmental index is positively influenced by zinc supplementation but the mental developmental index is not influenced by the supplementation. Conclusions: Zinc supplementation with 10 mg of zinc sulphate to infants with low birth weight during 6 months may be beneficial for increasing weight and motor development.

Published: July 2024

Objective: The effect of cervical vagal trunk stimulation on conduction between left superior pulmonary vein and left atria and atria fibrillation have not been systematically studied. We attempted to investigate the electrical conduction between LA and LSPV in dogs with cervical vagal trunk stimulation and evaluate the possible underline substrates for local reentry and initiation and maintenance of AF. Methods: 12 mongrel dogs (18-25 kg) underwent cervical vagal trunk stimulation at high-frequency (60 ms, 1-4V) to produce sinus arrest lasting >2 seconds,complete atrioventricular AV blocking or the sinus rate decreasing more than 50%. Left lateral thoracotomy was performed and the heart was exposed in a pericardial cradle. The HRA, LAA, PV-LAJ, LSPVm and LSPVd was locally stimulated (100 ms, 2-8V). ERP of HRA, LAA, PV-LAJ and within LSPV, ERP heterogeneity within LSPV and conduction between left superior pulmonary vein and left atria and atrial fibrillation inducing rate with vagal response was analyzed. Results: 1. During cervical vagal stimulation, the heart rate was reduced significantly from baseline 156±34 bpm to 75±34 bpm (p< 0.05, n=12), ERP of HRA,  LAA, PV-LAJ, LSPVm and LSPVd sites was shortened locally in all animals, ERP hetero-geneity (COV-ERP ) was increased from baseline 3±3% to 30±13% (on average, p< 0.05; n=12) and inducibility of AF was increased from baseline 49.9% to 70.9% with S1S1stimulation (100 ms, 2-8V) and from baseline 3.7% to 43.5% with S1S2 (5 ms decremented stepwise S1S2 300/200 ms, 2-8V, n=12; 2. LA and PV potentials at LA, PV-LAJ, LSPVm and LSPVd was overlapped during sinus rate and separated remarkably by stimulating at distal part of LSPV (n=9); 3. Unidirectional and bi-directional conduction(n=9), bi-directional decremented conduction (n=6), delayed conduction from LSPVp to LSPVd (n=12) and slow conduction from stimulating signal to local tissue potential (n=9) before onset of AF were recorded by pacing from both LSPV and LA. Conclusion: Our study strongly suggested that fast ectopic beating, abnormal vagal nerve activation as well as remodeling conduction between left superior pulmonary vein and left atria might are the common underline substrates for local reentry and AF initiation and maintenance.
Policy Brief No. 9. Urban community gardens as a strategy to promote integral agriculture in popular neighbourhoods
Authors: Franco Calderón Ángela María , Jaramillo Díaz Isabella , Sepúlveda Andrés
Published: July 2024

Factors such as population growth, rapid urbanisation, climate change and unequal access to wealth have increased the food crisis in the world, which was exacerbated by the COVID-19 pandemic. This crisis, which has had a greater impact on middle- and low-income countries, has highlighted the dependence of cities on food produced in rural areas of each country or even from other countries. As a contribution to the global discussion on food sovereignty, this Policy Brief focuses on demonstrating the benefits of local food production in urban community gardens to ensure access to healthy food within the framework of processes for the collective construction of the territory in popular neighbourhoods. In addition to the production of food for local consumption or marketing, it will be shown how these gardens fulfil spatial functions such as the recovery of deteriorated urban spaces, and educational functions such as the protection of nature and the exchange and transmission of ancestral knowledge.

Massive bone defect in open leg fracture: A case report
Authors: Placella Giacomo , Abu Mukh Assala , Ometti Marco , Salini Vincenzo
Published: July 2024

Open fractures with massive defects are likely the most challenging conditions to manage in traumatology, particularly due to the scarcity of cases described in the literature where limb preservation was feasible. This report illustrates the management of an open fracture with a massive bone defect in which the physicians recurred to amputation after an attempt to preserve the patient’s quality of life through initial reparative treatment. A 57-year-old male presented with an open fracture with a de novo 25-cm bone defect following a motorcycle accident. Despite the large laceration, the injury presented with a relatively conserved surrounding muscular tissue; the distal two-thirds of the tibia were missing; yet, no neurovascular damage was documented. The patient was managed with a temporary external fixator and antibiotic-loaded cement spacer. Due to the patient’s desire to ride his motorcycle again, the authors performed a custom-made tibiotalar nailing arthrodesis 22 weeks later. This case presented the risk of infection and low quality of life, which led to amputation 74 weeks after the nailing procedure was performed. The treatment remains challenging in cases of massive bone defects and a relatively preserved biological-functional environment, and efforts should be made to develop tailored strategies. Although individualized care provides patients with time and hope, it might still fail to guarantee a decent quality of life and risks being a temporary solution before reverting to amputation.
The effect of core stabilization exercises on balance and functional performance in individuals with functional ankle instability: An open-label randomized controlled trial
Authors: Panhale Vrushali P. , Walankar Prachita P. , Chheda Disha V.
Published: July 2024

Objectives:

The objective of the study was to evaluate the effect of core stabilization exercises on balance and functional performance in functional ankle instability (FAI).

Methods:

An open-label randomized control pilot study was conducted with 30 FAI participants allocated to two groups. Inclusion criteria were the presence of frequent ankle sprains, sense of give-away of the ankle, and identification of FAI score >11. The experimental group (n = 15) received core stabilization exercises along with conventional exercises, whereas the control group (n = 15) received only conventional exercises. The intervention period was six weeks. The outcome measures for static balance, dynamic balance, and functional performance were the single-leg stance test, modified star excursion balance test (mSEBT), and side hop test, respectively. The assessment was done at baseline and six weeks post-intervention.

Results:

Within-group analysis showed improvement in the single-leg stance test and all direction reach distances of mSEBT in both groups using the Wilcoxon signed-rank test. Meanwhile, the side hop test revealed no difference between the two groups. A significant improvement was seen in mSEBT and single-leg stance scores (P ≤ 0.05) between the groups using the Mann–Whitney U-test. However, the side hop test showed no significant difference (P > 0.05).

Conclusion:

The present study concludes that core stabilization exercises improved balance compared to mobility and strengthening exercises. Hence, it is highly recommended that core stability training be implemented as a holistic approach to managing FAI.

Подводная лодка очень сложное техническое устройство. Ее прочный корпус включает в себя невероятный сгусток несовместимого. Оружие, электротехника, электроника, горюче-смазочные материалы, газовые смеси и все это под высоким давлением и в агрессивной среде. В экстремальных условиях подводные лодки разных стран участвуют в великом противостоянии на предельных глубинах Мирового океана. Наш мир так нестабилен. Любое непродуманное действие, угроза действием и даже слово может привести к конфликту, в том числе военному. Конечно, речь идет о государственном уровне, но от этого не легче. И дабы, не допустить конфронтации, нужно детально отслеживать и анализировать любые факты столкновений, в том числе в сфере «гидрокосмоса». Может быть, в будущем это поможет отстоять хрупкий мир на нашей планете. В данной статье разобраны случаи боевого применения подводных лодок после Второй Мировой войны, в международных военных конфликтах, а также некоторые размышления о эффективности подводных лодок в современной войне.

Liszt & Henselt. (Part I) «Honored colleague and beloved friend»: the history of relations between Franz Liszt and Adolf von Henselt, recreated by their correspondence
Authors: Скорбященская О.А.
Published: July 2024

Статья посвящена истории взаимоотношений Ференца Листа и петербургского пианиста, композитора и педагога Адольфа фон Гензельта (1814–1889). В исполнительстве, композиторском творчестве, жизни Лист и Гензельт были полными противоположностями: первый был знаменитым европейским виртуозом, второй – забытым почти сразу же после смерти петербургским музыкантом; первый воплощал романтический артистизм, второй отказался от исполнительской карьеры, замкнувшись в учительском ремесле, первый являлся типичным экстравертом, второй – интровертом. Тем не менее, их дружба и творческий диалог продолжались почти 40 лет. Статья основана на неизвестных архивных материалах, находящихся в архивах и библиотеках Санкт-Петербурга, Москвы, Веймара и Швабаха. Актуальность исследования и его новизна характеризуются тем, что в данной статье впервые вводятся в научный обиход неизвестные архивные материалы, а также дается новая интерпретация уже опубликованных писем Листа и Гензельта. Цель исследования – дать сравнительный портрет двух выдающихся европейских романтиков, определивших развитие пианизма ХIX века, изучив их эпистолярию, а также нотные манускрипты, содержащие эскизы II части Концерта Гензельта f-moll ор. 16 и его Этюда D-dur ор. 2 № 9.

The article is devoted to the history of the relationship between Franz Liszt and the Petersburg pianist, composer and teacher Adolf von Henselt (1814–1889). In performance, composer creativity, life, Liszt and Henselt were complete opposites: the first was a famous European virtuoso, the second was forgotten almost immediately after his death St. Petersburg musician; the first person embodied romantic artistry, the second one abandoned his performing career, closed himself in the teacher's craft; the fi rst was a typical extrovert, the second was an introvert. Nevertheless, their friendship and creative dialogue lasted almost 40 years. The article is based on unknown archival materials, located in the archives and libraries of St. Petersburg, Moscow, Weimar and Schwabach. The relevance of the research and its novelty are characterized by the fact that in this article unknown archival materials are introduced for scientifi c use for the fi rst time, and a new interpretation of the already published Liszt and Henselt letters is given. The aim of the research is to give a comparative portrait of two outstanding European Romantics who determined the development of the 19th century pianism, having studied their epistolary, and also musical manuscripts containing sketches of the second part of Henselt's Concerto in F minor op. 16 and his Etude in D Major op. 2 No. 9.
Construcción de portafolios considerando momentos superiores para fondos de inversión
Authors: Ossa Gonzalez Genjis A. , Rojas Domínguez Miriam
Published: July 2024

El objetivo de este estudio es construir un portafolio utilizando Momentos Superiores y considerando activos tipo ETF. Se emplea una metodología cuantitativa que no solo se basa en la normalidad de la utilidad esperada, sino también en la inclusión de momentos superiores. El objetivo final es optimizar la utilidad de cada portafolio y determinar los tres mejores. Al analizar los rendimientos de la cartera compuesta por los activos LABU, PSQ, FXI, SPY e IWM, se observó una disminución en los rendimientos tanto en términos absolutos como porcentuales al considerar momentos superiores. Bajo condiciones de normalidad, la mayoría de los activos registraron rendimientos negativos, y esta tendencia se intensificó al incluir momentos superiores. En relación a los portafolios, se encontró que el Portafolio 2 mostró un desempeño destacado en términos de utilidad bajo la suposición de normalidad. A pesar de tener una curtosis notablemente más alta que los demás portafolios, este portafolio exhibió una media positiva más alta y una volatilidad más baja. Sin embargo, al considerar la ecuación de momentos superiores, se reveló que ninguno de los portafolios era viable como opción de inversión, lo que indica un mayor riesgo en todos ellos.
La comisión por amortización anticipada de préstamos hipotecarios en España. Una propuesta de mejora
Authors: González Velasco Carmen , González Fernández Marcos
Published: July 2024

El objetivo de este trabajo consiste en analizar la evolución de la normativa referida a la comisión por amortización anticipada de préstamos hipotecarios en España y en plantear una propuesta de mejora que beneficie más a los clientes que la normativa vigente. Para ello se analizan los efectos de esta evolución normativa sobre un caso distinguiendo diferentes escenarios de tipos de interés, con diferentes normativas y teniendo en cuenta la propuesta planteada. Los resultados muestran que las normativas que afectan a la aplicación de comisiones por amortización anticipada de préstamos han ido elevando el nivel de protección de los clientes de los servicios bancarios y el equilibrio entre las partes (prestamista y prestatario) a lo largo del tiempo. Por este motivo, con la normativa actual (Ley 5/2019) se aplican unas comisiones menores que con las normativas anteriores ya que se han eliminado las comisiones por amortización anticipada y se han establecido límites a la compensación por riesgo de interés que suponen un menor coste para los prestatarios cuando amortizan anticipadamente sus préstamos, pero sin producir escenarios adversos para los prestamistas debidos a la evolución de los tipos de interés. Además, la propuesta planteada sigue en esta línea de beneficio al cliente e incluso la mejora sustancialmente porque los componentes de la comisión se basarían en criterios de valoración financiera y la pérdida financiera para la entidad se mediría de forma más razonable.

An efficient one-step extraction method was developed for the recovery of additives and Non-Intentionally Added Substances (NIAS) from polystyrene, performed at room temperature for 2.5 hours, without grinding to avoid fostering the formation of NIAS unrelated to polymer processing. The study of NIAS is analytically challenging but with high importance since their presence is a potential threat to human health and to the environment while reducing plastic potential recyclability. For an understanding of NIAS formation and influence of processing parameters, a systematic approach was taken, using virgin polystyrene mixed with known quantities of standard additives as model materials. The degradation of one additive was identified and quantified (NMR, GC-MS) and the evaluation of analytical challenges, such as matrix effects was described. This method will help the quality control of virgin and recycled PS materials, including the food contact ones, and improve the knowledge of PS processing impact on NIAS formation.

Authors: Khan Izhar
Published: July 2024

Nashaat [25] introduced the powered inverse Rayleigh (PIR) distribution. It provides a better fit other than (inverse Rayleigh, Rayleigh, and Weibull) distributions. The moments of order statistics and recurrence relations for the single and double moments have been established. The computation of the means and variances are enumerated. These computations can be trulyinteresting and applied in numerous domains of study. Moreover, cumulative entropy (C.E.) and actuarial measures (A.M.) are also calculated to address the uncertainty in portfolio optimization. The usages of C. E. and A.M. are widespread in many real-word applications specifically in physical sciences and insurance science.

Authors: Baloush Malouh , Noiri T. , Talafha M. , Dzul-Kifli3 S. Che
Published: July 2024

In this paper, we introduce some types of separation axioms via $F$-open sets, namely $FT_i$ ($i = 0, 1, 2, 3, 4$), $F$-regular and $F$-normal spaces, and investigate their properties, relationships and characterizations. We show that every $FT_i$ space is a Ti space for $i = 0, 1, 2, 3, 4$. However, the converse is true whenever X is finite.

Published: July 2024

In this paper, we introduce hierarchy elements in an almost distributive lattice with respect to a non-empty set and obtain some of their algebraic properties. We characterize initial segments, ideals, and maximal sets in almost distributive lattices in terms of hierarchy sets and prove that the class of hierarchy sets forms a distributive lattice, which is not an induced sublattice. Also, we characterize hierarchy sets using compatible sets in an almost distributive lattice.
On the k-restricted Intersection Graph
Authors: Pelagio Mariane Eliz , Mendoza Kathlen , Mame Neil
Published: July 2024

The problem on intersection graph was introduced by Szpilrajn-Marczewski in 1945. This study introduces a new variant of intersection graph, called the $k$-restricted intersection graph. Let $\mathcal{S}_n$ be a nonempty $n$-element set, for some positive integer $n$ and let $S_{(n,k)}$ be the set of all the $k$-element subsets of $\mathcal{S}_n$ where $0\leq k\leq n$. A $k$-restricted intersection graph, denoted by $G_{S_{(n,k)}}$, is a graph with vertex set  $S_{(n,k)}$ such that two vertices $A,B\in S_{(n,k)}$ are adjacent whenever $A\cap B\neq \emptyset$ and $A\neq B$. Here, we determined the order and size of $G_{S_{(n,k)}}$. Moreover, some parameters such as independence number, domination number, and isolate domination number of the $k$-restricted intersection graph were established. Finally, necessary and sufficient conditions for a $G_{S_{(n,k)}}$ to be isomorphic to the cycle graph and complete graph were determined.
Structure of Primitive Pythagorean Triples in Generating Trees
Authors: Koszegyova Lucia , Csókási Evelin , Hirjak Juraj
Published: July 2024

A Pythagorean triple is a triple of positive integers $(a,b,c)$ such that $a^2+b^2=c^2$. If $a,b$ are coprime, then it is called a primitive Pythagorean triple.  It is known that every primitive Pythagorean triple can be  generated from the triple $(3,4,5)$ using multiplication by unique number and order of three specific $3\times3$ matrices, which yields a ternary tree of triplets. Two such trees were described by Berggren and Price, respectively. A different approach is to view the primitive Pythagorean triples as points in the three-dimensional Euclidean space. In this paper, we prove that the triple of descendants of any primitive Pythagorean triple in Berggren's or Price's tree forms a triangle (and therefore defines a plane), and we present our results related to  these triangles (and these planes).
