Multicriteria Decision Making for Fuzzy Set Based on Strategic Games
Authors: G.Vidhya  , K.Uma
Published: January 2023

A game is a decision-making situation with many players, each having objectives that conflict with each other. The players involved in the game usually make their decisions under conditions of risk or uncertainty. In this paper, a fuzzy approach is proposed to solve the strategic game problem in which the pure strategy set for each player is already defined. Based on the concepts of fuzzy set theory, this approach will use a multicriteria decision-making method to obtain the optimal strategy in the game, a method which shows more advantages than the classical game methods. Moreover, with this approach, some useful conclusions are reached concerning the famous ªprisoner's dilemmaº problem in game theory.
A Stochastic Model for Estimation of Mean and Variance of Time to Recruitment in a Two Graded Manpower System under Order Statistics Wastage with NonIdentically Inter-Decision Times
Authors: S.Jenita  , Selvi S.Sendhamizh
Published: January 2023

In this paper, an organization subjected to a random exit of personnel due to policy decisions taken by the organization is considered; there is an associated loss of manpower if a person quits the organization. As the exit of personnel is unpredictable, a recruitment policy involving two thresholds, optional and mandatory is suggested to enable the organization to plan its decision on appropriate univariate policy of recruitment. Based on shock model approach, a mathematical model is constructed using an appropriate univariate policy of recruitment. The analytical expressions for mean and variance of time to recruitment is obtained when ( i) the loss of man hours forms an order statistics (ii) the inter-decision times are sequence of independent and non-identically distributed exponential random variables (iii) the optional and mandatory thresholds having exponential distribution.

Optimal Control for Perishable Inventory with Partial Backlogging in a Supply Chain: MDP Approach
Authors: P. K Santhi  , C. Elango
Published: January 2023

In this paper, we consider a continuous review perishable inventory control with partial backlogging at retailer in a two stage supply chain. The supply chain consists of a distribution center DC) and single retail-vendor (RV). Arrival of demands to a retailer node is assumed to be Poisson and lead times are exponentially distributed at retailer node and Distribution center with parameters µ0 and µ1 respectively. The items are supplied to the retailer in packs of fixed size. The system is formulated as a Markov Decision Process (MDP). A stationary cost structure is imposed and an optimal stationary policy is obtained by using Linear Programming technique. Numerical examples are provided to illustrate the problem.
A Two Echelon Subsutable Inventory Model for Deteriorating Items
Authors: K.Marisamy  , K. Krishnan
Published: January 2023

This paper presents continuous review two-echelon inventory systems with two different substitutable items in stock. The demand for the products follows independent Poisson with rates λ1 and λ2 respectively for product and A and B. The operating policy at the lower echelon for the products are (si , Si) that is whenever the inventory level drops to ‘si’ on order for Qi = (Si-si) items is placed, the ordered items are received after a random time which is distributed as exponential. We assume that the demands accruing during the stock-out period are lost. The retailer replenishes the stock of products from the supplier which adopts (0,Mi) policy. The joint probability disruption of the inventory levels of the products, at retailer and the products at supplier are obtained in the steady state case. Various system performance measures are derived and the long run total expected inventory cost rate is calculated. Several instances of numerical examples, which provide insight into the behavior of the system, are presented.

O conto de fadas transvendo o mundo: criatividade, imaginação e fantasia nas aulas de Língua Portuguesa do Ensino Fundamental
Authors: Dias Aline Milena Borges da Silva
Published: January 2023

Este trabalho é resultante de um projeto didático desenvolvido na disciplina de Estágio Curricular Supervisionado em Português III, na Universidade Federal de Pernambuco (UFPE), que objetiva despertar, em alunos do sexto ano da modalidade regular de uma escola estadual de Igarassu-PE, além do interesse e curiosidade pela leitura do texto literário, um senso criativo para construção de releituras das histórias atemporais dos contos de fadas. O projeto atende a uma regência de 20 horas-aula e foi realizado em sequência ao período de observação da escola e da turma, realizado no mesmo tempo de duração. Sendo assim, para o seu planejamento, foram analisadas questões do cotidiano e cultura escolar, das relações em sala de aula e da prática pedagógica da professora supervisora do estágio. Portanto, a partir das provocações geradas pela leitura/escuta dos contos de fadas e do tensionamento dos elementos que compõem a sua materialidade multissemiótica, foram conduzidos momentos de pesquisa, reconto e produção de releituras, nos quais foi possível aprofundar (e mesmo introduzir) os alunos no universo mágico dessas histórias bem como recriá-las ludicamente através de modos alternativos de imaginar e conceber seus personagens.

The nature of investment climate through a facet of public investment: The emerging market case
Authors: Mpanza Sinakhokonke , Mashau Pfano
Published: January 2023

The purpose of this article is to table the nature of investment climate through a perspective of public investment. The investment climate of a city is the responsibility of the city’s municipal management (Biyase & Rooderick, 2018). Thus, this article provides insight into public investment in order to highlight the public sector’s role to ensure a good investment climate. The article focuses on KwaZulu-Natal secondary cities, particularly Newcastle and the City of uMhlathuze (Richards Bay). This article followed a qualitative approach. Data was collected through semi-structured interviews. Thematic data analysis was adopted with the aid of NVivo version 12. Analysis and interpretation of the result are presented through models developed from NVivo. The key finding of this article discusses investment climate in secondary cities through the lance of the public sector’s role in attracting investment by packaging effective investment incentives, planning and executing programs and projects to attract and retain investment, and targeting countries for inflow foreign direct investment based on the city’s sectors, not political diplomacy. Moreover, key findings reveal that each of the identified cities has autonomous independence to package their own investment incentives to advance their investment climate. Respondents pointed out that Richards Bay has an industrial development zone that is aimed at attracting investors across the globe. Furthermore, respondents highlighted that the city has investment incentives, but they are not applicable to the city.
HPV Vaccine Trends and Attitudes since the COVID-19 Pandemic
Authors: Bharat Nisha , Ziegler Andrea , THORPE ERIC
Published: January 2023

Introduction: Vaccine hesitancy has historically played a large role in
the low rate of the human papillomavirus (HPV) vaccine coverage in the
United States and has further surfaced to the forefront of public
discourse since the start of the COVID-19 pandemic. This study aims to
determine how HPV vaccination attitudes and trends among primary care
physicians and patients have changed since the COVID-19 pandemic.
Design: Physicians and patients (aged 9-45) participated in a voluntary
survey regarding HPV vaccination. In patients under 18 years of age, the
survey was completed by the patient’s parent or guardian. Results: Of
the 27 healthcare providers surveyed, 22.2% agreed that there has been
an increase in misinformation about the HPV vaccine since the COVID-19
pandemic and 7.4% of providers believed that patients were less willing
to discuss or receive the HPV vaccine. A majority of patients surveyed
(87.7%) were aware of the HPV vaccine but only about a third of those
patients had received all three doses of the vaccine (28.1%).
Conclusion: Recent trends in receiving the HPV vaccine may be associated
with the polarizing climate during the COVID-19 pandemic. Understanding
how trends in vaccine hesitancy have changed since the pandemic will
allow further and more targeted efforts to increase HPV vaccine uptake.
Management of acute invasive fungal rhinosinusitis with orbit-cranio-facial involved------ our experience with 8 cases
Authors: Yang Yang , Shen Li-Fang , Wang Feng , Chen Haihong
Published: January 2023

Key points:  Diagnosis of AIFRS should be alert in the
immunocompromised patient presenting with new-onset, rapidly progressive
sinusitis with facial-cranio-orbital spread.  Extended debridement
should be considered on a case-by-case basis.  Antifungal agent
contributed greatly to the outcome of AIFRS.  Prognosis mostly up to
the balance of underlying disease and fungal invasion, more emphasizes
should be focused on comprehensive treatment.  AIFRS with
facial-cranio-orbital involved often had a disastrous end.
Intraspecific trait plasticity to N and P of the wetland invader, Alternanthera philoxeroides under flooded conditions
Authors: Harms Nathan , Knight Ian , DeRossette Ashton , Williams Dean A.
Published: January 2023

Interactions between invaders and resource availability may explain
variation in their success or management efficacy. For widespread
invaders, regional variation in plant response to nutrients can reflect
phenotypic plasticity of the invader, genetic structure of invading
populations, or a combination of the two. The wetland weed Alternanthera
philoxeroides (alligatorweed) is established throughout the southeastern
USA and California, and has high genetic diversity despite primarily
spreading clonally. Despite its history in the USA, the role of genetic
variation for invasion and management success is only now being
uncovered. To better understand how nutrients and genotype may influence
A. philoxeroides invasion, we measured the response of plants from 26 A.
philoxeroides populations (three cp haplotypes) to combinations of
nitrogen (4 or 200 mg/L N) and phosphorus (0.4 or 40 mg/L P). We
measured productivity (biomass accumulation and allocation), plant
architecture (stem diameter and thickness, branching intensity) and
foliar traits (toughness, dry matter content, percent N, percent P). A
short-term developmental assay was also conducted by feeding a subset of
plants from the nutrient experiment to the biological control agent
Agasicles hygrophila, to determine whether increased availability of N
or P to its host influenced agent performance, as has been previously
suggested. A. philoxeroides haplotype Ap1 was more plastic than other
haplotypes in response to nutrient amendments, producing more than
double the biomass from low to high N and 50-68% higher shoot:root
ratio than other haplotypes in the high N treatment. A. philoxeroides
haplotypes differed in 7 of 10 variables in response to increased N. We
found no differences in short-term A. hygrophila development between
haplotypes but mass was 23% greater in high than low N treatments. This
study is the first to explore the interplay between nutrient
availability, genetic variation, and phenotypic plasticity in invasive
characteristics of the global invader, A. philoxeroides.

Kardec e a "desmaterialização" dos Espíritos. Um texto esquecido da escala espírita na primeira edição de O Livro dos Médiuns
Authors: Farias Luciana , Chibeni Silvio
Published: January 2023

Neste artigo analisamos os três parágrafos que tratam da desmaterialização dos Espíritos, incluídos no final da introdução da Escala Espírita publicada na primeira edição de O Livro dos Médiuns. Estes parágrafos são de significativa relevância para a teoria espírita, mas em geral não são conhecidos pelo leitor espírita médio, já que constaram apenas nessa versão do texto da Escala, suprimida a partir da segunda edição do livro. O esboço de uma análise histórica e filosófica da expressão “desmaterialização do Espírito” foi construído a partir das referências, em Kardec, mais úteis para a compreensão do texto e da perspectiva espírita dualista do homem, uma versão da tese metafísica do "dualismo" entre "matéria" e "espírito" constatada empiricamente pela sobrevivência do homem à morte do corpo. No texto, Kardec associa a "desmaterialização" do Espírito ao seu adiantamento espiritual, e analisa suas repercussões no perispírito, entre as quais a ampliação de sua capacidade de percepção.

Published: January 2023

The first ethnologists in Serbia appeared in the last decade of the 19th
century. The Department of Ethnology at the Faculty of Philosophy in
Belgrade was founded in 1906. The first woman with a degree in ethnology in
the period before the Second World War was Milena Lapcevic. After the Second
World War, enrolment of women in ethnology department at the Faculty of
Philosophy in Belgrade increased. In the 1950s, women graduate ethnologists
get the opportunity to work as lecturers. Until the 1970s professors at the
Department of Ethnology were mostly men. However, since then, women have
taken over the primacy at the department. Hence, the inclusion of women in
teaching expands research topics. This paper gives an overview from the
beginnings of the work of women ethnologists in education as well as their
research areas.

Aphids (Hemiptera: Aphididae) on alfalfa in Serbia: Seasonal dynamics and pest status
Authors: Jovicic Ivana , Radonjic Andja , Petrovic-Obradovic Olivera
Published: January 2023

Alfalfa (Medicago sativa) is the most important forage legume and one of the
most widely grown crops in Serbia. Aphids (Hemiptera: Aphididae) are one of
the most significant groups of pests of that crop. Three aphid species,
Acyrthosiphon pisum, Aphis craccivora and Therioaphis trifolii, are
considered as important pests of alfalfa in Serbia. The most abundant of
them, T. trifolii, is more adapted to warmer temperatures and it is the
predominant aphid species during summer months, while A. pisum is prevalent
during the spring period. In warmer climates, an increasing abundance of T.
trifolii and decreasing populations of A. pisum have been observed in
alfalfa in Serbia. On the other hand, A. craccivora is a minor pest of
alfalfa, which rarely occurs in high numbers. The present paper synthesizes
the existing knowledge about these three aphid pests of alfalfa, including
their morphology, biology, seasonal dynamics, pest status and effects of
temperature on their development.

Published: January 2023

The intensification of municipal-solid-waste (MSW) production, energy usage, and the curb of the landfill have developed the need for our society to use MSW under the vision of a waste-to-energy (WTE) approach to eradicating MSW as well as to address the energy issues across the world. The WTE alteration is an environment-friendly way of disposing of MSW. This study examines the usage of plastic, wood, and paper for refuse-derived fuel (RDF) production. The RDF is solitary of MSW energy yields, whose dependability and superiority are analysed in the current work. Two different RDF have been obtained from diverse waste streams at the plant site to find the finest RDF based on energy efficiency. Plastics, wood, and paper are the principal constituents in the method of occupied RDF. The results exhibited that the RDF-PA holds a high amount of carbon as-well-as hydrogen content and a decent calorific value, which leads to better fuel quality. The retention time under combustion and pyrolysis, the volatile matter portion of RDF, has increased accordingly. As per obtained results, RDF-PA is a good option for energy applications and fuel for combustion and pyrolysis reactions.
Heat transfer enhancement in inserted extruded aluminum finned tubes
Authors: Deng Shifeng , Shao Huaishuang , Jiao Jian , Qu Teng , Zhao Qinxin
Published: January 2023

Heat transfer enhancement in tubes is widely applied in various industrial processes. The traditional method of heat transfer enhancement is to insert radial fins to expand the internal surface area and destroy the flow. However, there is a flue gas corridor in the central area of the tube, and the cost of expanding the inner fin is high. A centrally symmetrical bent extruded aluminum fin was developed to enhance the heat transfer in the tube. An experimental platform was constructed to test the performance of inner finned tubes and explore the process of combining extruded aluminum inner fin with steel tube. The bent extruded aluminum fins with two side fins extending to the central axis possesses the best comprehensive heat transfer performance. The heat transfer correlation of the optimal fin structure is Nu = 0.864Re0.4275Pry0.3818(Pry/Prw)?0.1004. With low cost and strong heat transfer performance, the bent extruded aluminum inner fin tube will gain wide applications in the engineering field.

Authors: Souza Anderson , Sato Andre , Ochoa Alvaro Antonio Villa , da Costa Jose Angelo , Michima Paula Suemy Arruda
Published: January 2023

This paper aims to select the most suitable working fluid to be applied in a high temperature regenerative hot-source ORC, such as those driven by biomass, for climatic conditions measured from real data in Bom Jesus da Lapa in northeastern Brazil. To this end, the most commonly used working fluids in these systems were selected among numerous authors, discarding those with high GWP and ozone depletion potential and those classified as wet according to the slope of their temperature-entropy diagram. Then, from the model developed in the software EES, the simulation and performance analysis of the proposed system was performed based on thermal efficiency. It was conducted a fluid selection from the adaptation and expanding the parameters of the qualitative spinal point method, considering the thermodynamic performance, environmental preservation criteria, safety, and fluid characteristics. As a result, it was obtained that hydrocarbons present the best thermodynamic and qualitative performances, with benzene and cyclohexane being the most attractive to be used as fluids in the proposed Rankine cycle, followed by n-hexane.

It is significant to study oxygen adsorption understand the mechanism of coal spontaneous combustion. In this paper, based on the fractal dimension of coal and the self-similar fractal geometry, the internal pore structure of coal is modeled. Then, the lattice Boltzmann method is employed to conduct the numerical simulation of oxygen adsorption in coal. Compared with the existing experimental data and numerical simulation, the lattice Boltzmann method is verified to be correct. The numerical results indicate that in the process of oxygen adsorption in coal, the preferential flow occurs when the large pores connect to the channel. In the meantime, the large diffusion coefficient leads to an early time for adsorption equilibrium. The oxygen adsorption increases with an increased adsorption rate constant. Pore structure plays a significant role in the adsorption behavior of oxygen in coal. The results can provide theoretical support for reducing coal spontaneous combustion and ensuring coal mine safety in production.

The lance is a critical component of the bottom-blowing pool melting process, and its placement has an important impact on the pool?s gas-liquid two-phase flow. In this study, a mathematical model of the bottom-blowing process is established, and the flow pattern, trajectory, wake vortex, and velocity of bubbles under four lance spacings are simulated. Results show that there are three basic bubble flow patterns appear in the flow field: bubbles coalesce before leaving the nozzle (Pattern ?), bubbles coalesce after leaving the nozzle (Pattern ?), and no coalescence during the rise of bubbles (Pattern III). The bubble pattern varies from Pattern I to Pattern III with the increase in lance spacing. The intensity of the influence of the wake vortex on the bubbles decreases. The Q (the Q is the second Galilean invariant of the velocity gradient tensor ?v) value of the wake vortex is small, but the vortex structural distribution is complex. Moreover, there is a large velocity difference between gas and liquid at the beginning of gas injection, but the velocity difference between them decreases after gas injection, so the average turbulent kinetic energy in the pool initially increases sharply, and then approaches dynamic equilibrium. The top and bottom velocities of the bubbles are consistent, and the velocity fluctuation is orderly. Moreover, the greater the lance spacing is, the greater the disturbance in the pool is. The mixing effect of D = 0.2 m is the best among the four spacings.

In this work, a validated finite element-based coupled optical, thermal, and electrical model is used to assess the performance of a dual concentrated photovoltaic system thermally regulated using a PCM for the environmental conditions of Lahore, Pakistan. Thermal management of the system is achieved using a selected PCM. That has a melting temperature of 53-56?C, a thermal conductivity of 19 W/mK, and heat of fusion of 220 kJ/kg. Thermal regulation and power output of the system are analyzed for a clear day of six months of a year. It is found that the maximum temperature of the upper PV cell is ~80?C while for the bottom PV cell is ~82?C in July. The percentage power gain obtained after the addition of an upper concentrated PV cell is ~17.9%. The maximum and minimum power of the system is found to be 0.079 kWh/day/m2 and 0.041 kWh/day/m2 in May and November, respectively.

Objective: To compare postpartum glucose tolerance between women treated for gestational diabetes (GDM) and those not treated.

Methods: Metabolic testing was performed at 3-months and 1-year postpartum in 599 women comprising the following gestational glucose tolerance groups: (I) normal glucose challenge test (GCT) and oral glucose tolerance test (OGTT) in pregnancy; (II) abnormal GCT with normal OGTT; (III) gestational impaired glucose tolerance; (IV) mild untreated GDM; and (V) severe treated GDM.

Results: Birthweight progressively increased across Groups I-IV, before falling steeply in treated GDM (p<0.0001). In contrast, at 3-months and 1-year, insulin sensitivity and beta-cell function progressively decreased across the 5 groups, mirrored by rising fasting and 2-hour glucose (all p<0.0001). Accordingly, prevalence of pre-diabetes/diabetes at 1-year increased in a stepwise manner across Groups I-V (2.8%, 9.6%, 13.5%, 21.5%, 32.6%; p<0.0001).

Conclusion: Treating GDM lowers birthweight but does not disrupt the association between gestational glycemia and maternal pre-diabetes/diabetes after pregnancy.

The COVID-19 pandemic has resulted in increased attention on infection prevention measures. This study aims to assess whether changes in hand hygiene procedures, use of personal protective equipment and moisturizers during the first year of the COVID-19 pandemic were associated with changes in the occurrence of skin symptoms among healthcare workers, cleaners, and day-care workers. A total of 602 participants (40%) responded to an electronic questionnaire, including questions on previous and current occupational exposure and skin problems. Increased frequency of hand washing, use of hand disinfectants, use of disposable gloves and moisturizers were all associated with an increased symptom score on the hands, wrists, forearms. Participants who increased their use of masks or respirators had a higher risk of facial skin symptoms, compared with those with non-increased occupational exposure. In conclusion, a change of behaviour among healthcare workers, cleaners and day-care workers during the first year of the COVID-19 pandemic, with an increase in occupational exposures and use of moisturizers, was associated with higher occurrence of facial skin symptoms and symptoms on the hands, wrists and forearms.

The principles of parenting related to character development, including exemplary, togetherness in realizing moral values, democratic behavior, honesty, the ability to appreciate children's development and unity of words and actions. The original purpose of this study was to determine the role of parents in the formation of children's character in RA. Al-Miftah, knowing the conflicts that parents face in making children's characters and revealing the consequences of the role of parents on the character of early childhood. as a result of interviews using a group B teacher to be a class teacher at RA. the teacher of group B stated that the students were conducted by class teachers and accompanying teachers. Assistant teachers are assigned to identify children with special needs in care. Identification of learning needs is carried out using an exclusive plunge into the field, delivering instruments and guidance. Based on the data that has been observed by researchers regarding the role of parents in shaping the character of their students, most of the parents answered that they often guided 6 people (60%), who answered that they often guided their children as much as 4 people (40%), and those who answered do not guide their children. there are no children (0%), then the conclusion of the respondents regarding the involvement of parents in the formation of the character of students is very good.
Hantken Miksa és a tudományos névadás
Authors: Kovács Zoltán
Published: January 2023

A Földtani Közlöny 152/2. kötetében megjelent egy tartalmas tanulmány Hantken Miksa tudományos örökségéről (Görög et al. 2022), mely többek között összegyűjtötte az összes olyan taxonnevet, amit vagy Hantkenről neveztek el, vagy a jeles kutató tudományos névadói tevékenységével függ össze. Jelen írásommal az a célom, hogy kiegészítsem az említett cikket, és HANTKEN szerzőségével kapcsolatban néhány adatot tisztázzak. Mint az köztudott, a taxonnevek alkalmazhatóságát, érvényességét és a szerzőség kérdését a Zoológiai Nevezéktan Nemzetközi Kódexe (ICZN, magyarul ZNNK) tárgyalja. Az előbbi legújabb változata elérhető az interneten (www.iczn.org/ the-code/the-code-online); a magyar fordítás (ZNNK 1989) ugyan a kódex egy korábbi állapotát tükrözi, azonban az idevágó cikkelyek lényegében változatlan tartalmúak. Két kérdéskört tekintek át, az első egy eocén gastropodához (Turritella tokodensis), a második a bakonycsernyei jura ammoniteszekhez kapcsolódó nevezéktani problémákat tárgyalja.
A Magyarországon felfedezett bakteriális gáz és biodegradált kőolaj előfordulásának genetikája
Authors: Koncz István

A szerző áttekintést ad a primer és a szekunder bakteriális folyamatokról. A Magyarországon felfedezett bakteriális gáz-telepek többségét, amelynek metánja izotóposan igen könnyű a szénizotóparány-adatok alapján, a primer bakteriális folyamatok hozták létre. Ezek a gáztelepek 500–1500 m mélységben találhatók, és a Hajdúság, a Nagykunság területek és a Békési-medence kiemelkedett részein helyezkednek el. Tekintve, hogy a képződött bakteriális metán nemvolt elegendő a gázfázis létrehozására, a telepek létrejötte a medencerészek kiemelkedésének tulajdonítható. Néhány esetben a termogén metán járult hozzá a víz gáztelítettségének növeléséhez, amely a mélyen fekvő anyakőzetekből vertikálisan migrált a sekély tárolókba.

On the Adekunle Ajasin University Main campus, Akungba-Akoko, Ondo State, Nigeria, the pollen morphological study of seven (7) flowering plant species representing three (3) angiospermic plant Families (Asteraceae, Euphorbiaceae, and Fabaceae sub-family Caesalpinoideae) was examined, analyzed, and studied palynologically  to determine the morphological features and attributes as an aid in the identification and classification of its members within each family.  Pollen grains from fresh polleniferous materials were extracted using acetolysis methods. Detailed morphological evaluations were performed at x100 magnification. Results showed similarities and differences between species in the same genera, as well as differences between species in other families. Pollen study of these species revealed several similarities between species within the same family. Aperture type, forms, pollen grain size, sculpturing pattern, pollen dimension, and exine pattern were all studied for differences and similarities. Euphorbia hirta L and Euphorbia heterophylla L, both Euphorbiaceae species, have tricolpate apertures, are prolate in shape, reticulate, and contain small to medium pollen sizes. Asteraceae has tricolporate apertures, prolate spheroidal shapes, spinate, short and long spines, and pollen sizes ranging from microscopic to enormous (Ageratum conyzoides L, Tithonia diversifolia, and Tridax procumbens). Pollen from the family Fabaceae subfamily Caesalpinioideae (which includes Caesalpinia pulcherrima (L.) Swartz. and Senna alata (Linn.) Roxb) were found to be subprolate, coarsely reticulate, tricolporate, and with pollen sizes ranging from medium to large. Aperture measures such as number and diameter, pollen size, and spine height were suggestive in all of the species studied. Because all of the species studied exhibited comparable form and symmetry, they were grouped together and assigned to the same family.
