Authors: Makur Alberta Parinters
Published: October 2021

This study was performed to examine the students’ reading and math skills that affected their mathematics achievement. The objective of this research was to know the effectiveness of reading strategy (PQ4R strategy) on mathematical communication skill based on mathematical reasoning skill.It was quantitative research using quasi-experimental method conducted at SMAN 3 Depok in 2014 with 80 samples of students selected based on their mathematical reasoning skill. Data were obtained through questions about mathematical reasoning and mathematical communication and then analyzed with two-way ANOVA. The data analysis and interpretation showed that students who were taught with PQ4R strategy had better mathematical communication skill than students who have been traditionally taught. The effect of mathematical communication skill differed depending on mathematical reasoning ability. There was a more significant difference between students with high mathematical reasoning skill and low mathematical reasoning skill for students in the treatment condition than there was for subjects in the control condition. Thus, there was an interaction between the learning strategy and mathematical reasoning skill. The findings lead to the recommendation that reading skill could be used to improve student's mathematical communication skill and would ease the mathematical learning proces.test. DOI: https://doi.org/10.31235/osf.io/6xk7b

Authors: Панченко Сергей Леонидович , Ященко Сергей Михайлович
Published: October 2021

В статье поднимается актуальный вопрос, связанный с переработкой вторичных ресурсов предприятий пищевой промышленности. Основной целью является разработка методики исследования процессов охлаждения и замораживания. Проведен анализ источников загрязнения и состав стоков. Приведены виды современной очистки сточных вод. Рассмотрены характеристики процессов переработки – концентрирования экстрактов плодово-ягодного сырья вымораживанием c целью извлечения полезного для человека вещества – пектина, а также вымораживания жиросодержащего сырья предприятий переработки мяса, молока и растительных масел из сточных вод. Изготовление полезных продуктов из отходов производства не только решает проблему неполного использования входящих в сырье веществ, но и позволяет улучшить экологическую ситуацию, так как утилизация отработанного материала наносит огромный вред окружающей среде. Приведен экологический мониторинг отраслей пищевой промышленности с прогнозом использования вторичных ресурсов. Проведен эксперимент кинетики процесса замораживания настоев плодово-ягодного сырья с целью проведения процесса коагуляции и осаждения пектиновых веществ в виде осадка, после чего они легко удаляются фильтрованием. Получены температуры кристаллизации и начала образования кристаллов. Отмечено влияние параметра температуры на механическую очистку. Проведены исследования вымораживания жиров методом криогенного барботирования инертных газов. Приведена методика расчета энергетических показателей. Указаны характеристики фазового перехода экзотермического процесса охлаждения. Для получения кривых охлаждения и замораживания использовали хромель-копелевые термопары, связанные с потенциометром.

Коллагенсодержащая продукция оленеводства: новые пути рационального использования
Authors: Гордиенко Инна Михайловна , Белевцова Дарья Валерьевна
Published: October 2021

В статье представлены материалы по изучению возможности и разработке методики получения коллагена из лобашей северного оленя с перспективой использования его в пищевой промышленности. Результаты анализа химического состава и свойств лобашей позволяют констатировать, что данный вид сырья можно рассматривать как потенциальный источник для получения продуктов растворения коллагена (ПРК), так как они содержат более 90% белка, в том числе 75% коллагена. Подобраны режимы технологических операций, позволяющие получить ПРК методом щелочно-солевой обработки исходного сырья с последующим растворением полуфабриката в уксусной кислоте и диализом полученного продукта. Установлено, что наиболее эффективным является использование щелочно-солевого раствора, содержащего 10% гидроксида натрия. При этом выход конечного продукта по массе в 9 раз превышает массу исходного сырья. Показано, что основным компонентом полученного продукта является коллаген (94 % от массы сухого остатка). Установлено, что по микробиологическим показателям ПРК соответствует требованиям ТР ТС 021/2011, предъявляемым к пищевым продуктам. Проверка целесообразности использования ПРК из лобашей северного оленя в качестве пищевой добавки в образцах мясных колбас и котлет по результатам органолептической и потребительской дегустационной оценки показала, что добавление ПРК существенно улучшает показатели консистенции и сочности продуктов.Таким образом, новый подход к рациональному использованию коллагенсодержащей продукции оленеводства позволит восполнить дефицит пищевого белка за счет экологически чистого сырья, в связи с тем, что олени не подвержены заболеванию губчатой энцефалопатией в отличие от крупного рогатого скота.

Researchers have been studying wide-base tires for over two decades, but no evidence has been provided regarding the net benefit of this tire technology. In this study, a comprehensive approach is used to compare new-generation wide-base tires (NG-WBT) with the dual-tire assembly (DTA). Numerical modeling, prediction methods, experimental measurements, and environmental impact assessment were combined to provide recommendations about the use of NG-WBT. A finite element approach, considering variables usually omitted in the conventional analysis of flexible pavement was utilized for modeling. Five hundred seventy-six cases combining layer thickness, material properties, tire load, tire inflation pressure, and pavement type (thick and thin) were analyzed to obtained critical pavement responses. A prediction tool, known as ICT-Wide, was developed based on artificial neural networks to obtain critical pavement responses in cases outside the finite element analysis matrix. The environmental impacts were determined using life cycle assessment. Based on the bottom-up fatigue cracking, permanent deformation, and international roughness index, the life cycle energy consumption, cost, and green-house gas (GHG) emissions were estimated. To make the outcome of this research effort useful for state departments of transportation and practitioners, a modification to AASHTOWare is proposed to account for NG-WBT. The revision is based on two adjustment factors, one accounting for the discrepancy between the AASHTOware approach and the finite element model of this study, and the other addressing the impact of NG-WBT.
Relating fish distributions to physical characteristics of a tidal energy candidate site in the Banks Strait, Australia
Authors: Scherelis Constantin , Penesis Irene , Marsh Philip , Cossu Remo , Hemer Mark , Wright Jeffrey
Published: October 2021

With the tidal energy industry moving towards commercial-scale developments, it is important to consider potential interactions between tidal energy converters (TECs) and the marine environment prior to the instalment of large-scale TEC arrays. The Banks Strait, a tidal channel located in the northeast of Tasmania, Australia, was identified as a promising candidate site for tidal energy by the Australian Tidal Energy (AUSTEn) project. To gain an understanding about potential overlap between TEC arrays and fish usage of the Banks Strait tidal channel, fish density distributions were estimated from hydroacoustic surveys during the tidal resource characterization campaign. Differences in fish density were examined according to bottom–depth, bottom – type, current speed, temperature and vertical distribution. Fish densities were significantly higher at night and displayed preferences for depths between 20 – 40 m and current speeds between 1.75 – 2 m/s. Fish density was generally highest in the bottom 10 m from the sea floor at all depths sampled. Variation by temperature and bottom–type sampled was not significant. Future studies involving long-term, stationary surveys of fish densities along with repeated surveys across different seasons would provide a more wholistic picture of fish distributions in the Banks Strait to inform developers about potential device encounter probabilities.

Mid-Cretaceous ammonite zones, Western Interior, United States
Authors: Cobban William A.
Published: October 2021

The Western Interior of the United States contains an important sequence of middle Cenomanian-late Turonian ammonites. Ammonites from the northern part of the Western Interior are mostly North Temperate forms, whereas those from the southern part are a mixture of Tethyan and North Temperate forms. The ammonite succession in the southern part can be more finely zoned than that of the northern part, and offers better possibilities for international correlation.
In the zonation, the boundary between the middle and upper Cenomanian is placed at the top of the zone of Plesiacanthoceras aff. P. wyomingense. The top of the Cenomanian is drawn at the top of the zone of Neocardioceras juddii as recommended in a 1981 study by C. W. Wright and W. J. Kennedy. However, Mammites nodosoides, which occurs three zones higher, is usually regarded in Europe as basal Turonian, although Wright and Kennedy have now recognized a zone of Watinoceras coloradoense at the base, which lies below the zone of Mammites nodosoides. In the Western Interior, W. coloradoense is restricted to the zone of Vascoceras (Greenhornoceras) birchbyi, which is separated from the zone of Neocardioceras juddii by a zone of Pseudaspidoceras flexuosum. Inasmuch as the ammonites in the latter zone are closely related to those in the zone of V. birchbyi, a Turonian assignment seems best for the zone of P. flexuosum. Collignoniceras woollgari, which is widely distributed in Europe, Asia, and North America, is usually regarded as middle Turonian in a threefold division and late Turonian in a twofold division. I consider the species to mark the base of the middle Turonian. Where to place the top of the middle Turonian, however, is a problem. Inasmuch as the best fauna! break is at the top of the zone of Prionocyclus hyatti, that is where the boundary is placed in this report. Inoceramids in the zone of P. hyatti are characterized by forms having a radial depression like the middle Turonian Inoceramus hobetsensis of Japan.
The top of the Turonian is designated here at the top of the zone of Prionocyclus quadratus. Fossils of this zone include inoceramids of the fiegei-dresdensis group, which in Europe have been considered either very late Turonian in age or very early Coniacian. Prionocyclus quadratus is the youngest species of a lineage of prionocyclids. This species is succeeded by Forresteria (Solgerites) of Coniacian Age.

Correlation of the marine sequences is based in particular in ammonites, foraminifera, rudists and palynomorphs, and that of the nonmarine sequences on reptiles (including dinosaur eggs), fish, bivalves, ostracodes, conchostracans, insects, plants, charophytes and palynomorphs.
Proposals for the stratigraphic positions of the Berriasian - Valanginian and the Valanginian Hauterivian boundaries
Authors: Hoedemaeker Ph. J.
Published: October 2021

In two previous papers (Hoedemaeker, 1982, 1983) the author proposed to draw the boundary between the Berriasian and the Valanginian at the base of the TimoveUa alpiUensis Subzone, which he described from SE Spain. The correlation of this subzone with the published French zonation is however problema­tic, because the fauna) association of the alpillensis Subzone is unknown from France. He correlated the alpiUensis Subzone with the French Berriase/la callisto Subzone. In this paper he revised his previous correlation and equated his alpil/ensis Subzone with the greater upper part of the callisto Subzone. He correlated the lower part of the latter subzone, which probably covers the interval assigned to the callisto Subzone in the Berriasian stratotype, with the uppermost part of his Berriasel/a picteti Subzone in Spain. The author also proposed (1982, 1983) to draw the Valanginian - Hauterivian boundary between the Saynoceras verrucosum and Himantoceras trinodosum Subzones. This proposal is further elucidated in this paper. The two boundaries discussed here coincide with the peaks of two successive global sea level lowstands, well marked in the Vailian global coastal onlap curve as 'Basal Valanginian (131) global unconformity' and the 'Basal Hauterivian (126) global unconformity' (Vail & Todd, 1981; Ziegler, 1982).

Alegría, don y afecto en Pedro Salinas
Authors: SALAS HUGO
Published: October 2021

A partir de una lectura detenida del poema octavo de La voz a ti debida (1933) de Pedro Salinas, el presente artículo reformula el tema amoroso bajo las figuras de la alegría, el don y el afecto. La vinculación de la alegría al don, interpretado en la clave propuesta por Jacques Derrida, parece abonar las lecturas de aquellos críticos que han puesto en duda el carácter supuestamente neoplatónico de las inclinaciones del poeta. Tal perspectiva, en conjunción con una conceptualización del afecto a partir de los postulados de Spinoza, hace posible una nueva elucidación de un largo debate en torno al poemario; a saber, el grado de existencia y realidad de la amada. Por último, se plantea la coherencia de estas interpretaciones con las posiciones críticas y poéticas que el propio Salinas esbozara respecto de la tradición.
Heterotopías en la poesía femenina reciente. El locus amoenus en Yolanda Ortiz, Silvia Terrón y Pilar Astray Boadicea
Authors: VILLALOBOS PAULA FERNÁNDEZ
Published: October 2021

El locus amoenus es uno de los recursos clásicos más utilizados para representar el espacio desde donde la voz poética se enuncia. Dado que la constante vital de la poesía se encuentra sujeta al cambio y al devenir de su tiempo, y dado la actual proliferación de poesía escrita por mujeres, resulta necesario revisar el tratamiento que se realiza del tópico literario clásico dentro de la poesía femenina contemporánea. Considerando la fisionomía del mismo, se analizan tres poemarios significativos de tres poetas españolas nacidas a partir de los años ochenta, cuyas publicaciones tienen lugar en la segunda década del siglo XXI. En sus poéticas, el sujeto lírico crea espacios otros donde encontramos reminiscencias y elementos propios del locus amoenus. Descubrimos así a tres poetas que desarrollan estéticas novedosas en busca de nuevos horizontes donde posicionarse.
ESCALATION OF COMMITMENT AND CEO DEPARTURES: THEORY AND EVIDENCE
Authors: Chulkov Dmitriy V. , Barron John M.
Published: October 2021

The escalation of commitment process involves a decision-maker continuing commitment to an investment after receiving negative information. This study develops a principal-agent model to explore how escalation decisions are linked with departures of CEOs from the position. With asymmetric information, a CEO has an incentive to conceal prior decision errors by escalating commitment to failing investments and leaving the firm before the outcome of investment decisions is disclosed publicly. Results of empirical analysis based on a sample of over 3,000 US firms are consistent with the theory and demonstrate that firms’ reporting of low financial performance relative to their industry as well as initiation of new discontinued operations are preceded, and not followed, by unplanned CEO departures.
Strategy of Deterrence and Terrorism
Authors: JANKŮ Linda , SUCHÝ Petr
Published: October 2021

The article deals with deterrence of terrorism. The aim is to assess validity of a proposition that it is possible to deter terrorist groups, but there are some specifics in comparison to the deterrence of states. First, we determine deterrence threats which can be applied in relation to terrorist groups and discuss possible restraints of their application in practice. This is followed by an analysis of whether deterrence can be applied against all types of terrorist groups without distinction, where we develop a model of classification of terrorist groups according to the goals which they pursue. So far, the topic of deterrence of terrorism has not been discussed in detail in the Czech academic texts. This article thus seeks to fill this lacuna and highlight the benefits of applying deterrence strategy to the terrorist groups.
Record of hill stream catfish Glyptothorax telchitta (Hamilton-Buchanan, 1822) from Paschim Medinipur district, West Bengal, India

Glyptothorax telchitta (Hamilton-Buchanan, 1822) is a benthic hill-stream Sisoroid catfish that inhabits the mountain waters of the Indian Himalayas and in China, Tibet and the Sunda Islands. It is also a common hill stream catfish of the northern region of West Bengal. The present work reveals that the species is available in the Shilabati river basin, Ghatal, Paschim Medinipur, West Bengal. Therefore, Glyptothorax telchitta (Hamilton-Buchanan, 1822) is a widely distributed hill stream species and extends to the lowland area of Paschim Medinipur district of West Bengal, India.

Research on amphibians and their conservation have gained worldwide attention, as the group includes the highest number of threatened and Data Deficient species when compared to other vertebrates. However, amphibians have long been neglected in wildlife conservation, management decisions, policy making, and research agendas in Pakistan. In this paper, an annotated checklist of the 21 amphibian species of Pakistan, a key to their identification, and detailed discussions on variation in species, including the genera Minervarya and Sphaerotheca, are provided. We found a statistically significant difference in the morphometric measurements of males but non-significant difference in the females of the two forms (rusty dorsum and dotted dorsum) of S. maskeyi. Some genera, such as Microhyla, Uperodon, Minervarya, Allopaa, Chrysopaa, Euphlyctis, Nanorana, and Sphaerotheca, in Pakistan are in need of additional data for molecular and morphological comparisons with taxa in other South Asian countries. The predicaments of amphibian research in Pakistan are discussed, gaps identified, and suggestions are made. Although the occurrence of chytrid fungus in Pakistan is predicted of low likelihood, a lack of data merits studying the prevalence of the fungus, particularly in the northern regions of the country which exhibit complex and dynamic ecosystems. It is recommended that systematic and coordinated surveys are conducted throughout the country to build a database of species occurrences and distributions. Additionally, the monitoring of wild populations and threat mitigation, as well as appropriate legislation, are suggested as long-term measures. By adopting an inclusive wildlife conservation approach in Pakistan, amphibians could be integrated into wildlife conservation and management efforts.
Marine diversity in the biosphere reserve of the most oceanic island in the Gulf of California: San Pedro Mártir
Authors: Amador-Castro Imelda G. , Fernández-Rivera Melo Francisco J. , Torre Jorge
Published: October 2021

San Pedro Mártir island is of high biological, ecological, and fishery importance and was declared a biosphere reserve in 2002. This island is the most oceanic in the Gulf of California, and information on its rocky reefs is scarce. The present study aimed to generate the first list of conspicuous invertebrate and fish species based onin situobservations and to examine the community structure of the shallow rocky reefs of the reserve. In addition, we estimated the ecological indicators of richness, abundance, Shannon diversity, and Pielou evenness to evaluate the conservation status of the biosphere reserve. Data were collected annually from 2007 to 2017 through 2,192 underwater SCUBA transects. A total of 35 species of invertebrates and 73 species of fish were recorded. Most of the species are widely distributed along the eastern Pacific. Overall, 64% of the species found in this study are commercially important, and 11 species have been listed as protected. The abundance of commercially important invertebrate species (i.e., the sea cucumberIsostichopus fuscusand the spiny oysterSpondylus limbatus) is decreasing, while commercially important fish species have maintained their abundance with periods of increase. The ecological indicators and the abundance and size of the commercial species indicate that the reserve is in good condition while meeting its conservation objectives.
Le couple expatrié à distance : d’une illusion à l’autre
Authors: Lin-Pinçon Xiao-Hui Aurore
Published: October 2021

Cet article s’intéresse au couple à distance dans le contexte de l’expatriation. La réflexion porte sur les effets des séparations et des retrouvailles à travers la distance géographique, qui met progressivement en évidence l’étrangeté de soi et de l’autre dans les liens de couple. L’étrangeté peut s’éprouver de façon plus ou moins accentuée selon la culture du pays d’expatriation. La rencontre avec un couple dont les entretiens se sont déroulés en chinois illustre ces enjeux et interroge la position du clinicien dans sa double position dans le transfert et le contretransfert. L’article montre par ailleurs en quoi le virtuel à travers la tablette peut devenir un espace de jeu et de créativité au sens de Winnicott et entretenir l’illusion de la non-séparation. Il peut devenir un espace de besoin, qui peut faire barrage à une désillusion nécessaire et repousser les véritables retrouvailles du couple.
Accueillir un nouveau-né au temps du coronavirus : la fabrique de la famille au défi des interdictions de visite à l’hôpital
Authors: Pradillon Gaëlle
Published: October 2021

Les mesures sanitaires prises dans les hôpitaux durant l’épidémie mondiale de covid-19, notamment au cours de la « première vague », sont venues questionner l’auteure dans le cadre de sa pratique au sein d’un service de réanimation néonatale. La fermeture de l’institution hospitalière aux visiteurs au nom de la sécurité sanitaire a ainsi conduit à fermer les services de suite de couches aux pères et à limiter, voire interdire, les visites des parents auprès de leur nouveau-né hospitalisé. Comment inventer des moyens de faire famille au moment où la famille se constitue ou se réaménage dans des conditions aussi extrêmes ? Au travers de quelques observations et de l’analyse d’un cas clinique, l’auteure invite à repenser les pratiques limitant les visites des parents mais également des frères et sœurs auprès des bébés hospitalisés.
Les angles morts du droit antidiscriminatoire : éloge de la circulation des concepts
Authors: Ndjoko Hermann Martial
Published: October 2021

En droit français, la discrimination est contraire au principe d’égalité. Toutefois, pour que le cadre normatif permettant de juguler les pratiques discriminatoires soit efficace, encore faut-il pouvoir appréhender le phénomène dans toute sa plénitude et sa complexité. Le droit français, seul, ne peut repérer et combattre toutes les formes de discrimination, sans s’inspirer des créations conceptuelles venues d’autres disciplines ou d’autres droits. Dans cet article, l’auteur démontre que la circulation des concepts a un rôle positif à jouer dans les dynamiques de lutte contre les discriminations. Pour ce faire, il procède d’abord à l’analyse des modalités de circulation des concepts dans l’ordonnancement juridique, pour ensuite mettre en exergue les effets réels et potentiels de cette circulation sur le droit antidiscriminatoire.
France 2008 : pourquoi le nombre de naissances continue-t-il d’augmenter ?
Authors: Pison Gilles
Published: October 2021

L’effectif annuel des naissances a augmenté de 9 % depuis 10 ans en France métropolitaine, et l’indicateur de fécondité est passé de 1,65 à 2,00 enfants par femme entre 1993 et 2008. Contrairement à ce qu’on pourrait penser, ces hausses ne viennent pas d’une augmentation de la fécondité des couples d’une génération à l’autre. Ceux d’aujourd’hui ont en effet autant d’enfants que leurs aînés d’il y a trente ans. Mais ils les ont plus tardivement, ce retard ayant entraîné temporairement l’indicateur de fécondité successivement à la baisse puis à la hausse.
Terrains & travaux , 2000-2019
Authors: Dagiral Éric , Peerbaye Ashveen , Vincensini Caroline
Published: October 2021

Cet article propose une analyse à la fois quantitative et qualitative des vingt premières années de production de terrains & travaux . Dans le cadre de ce numéro anniversaire, il revient d’abord sur le projet éditorial de la revue et en précise le fonctionnement concret à travers les évolutions simultanées de son comité de rédaction, de ses rubriques, ainsi que des thématiques choisies au fil des ans. Il analyse ensuite en détail une série de caractéristiques des auteur·e·s des 359 articles publiés depuis 2000, puis esquisse la façon dont la revue se positionne dans l’espace plus large des revues de sciences sociales, ainsi que le paysage des auteur·e·s les plus cité·e·s que la revue donne à voir. Ces coups de projecteur mettent en évidence la relative professionnalisation de la revue depuis sa création comme « Cahiers du département de sciences sociales de l’ENS de Cachan ». Ils révèlent aussi la centralité de la sociologie dans la trajectoire de cette « revue de sciences sociales », centralité qui n’équivaut cependant pas à une exclusivité, la revue laissant une place non négligeable depuis sa création à d’autres sciences sociales à travers le comité de rédaction, les auteur·e·s publié·e·s et les références citées.
L’interprétariat à la Cour nationale du droit d’asile
Authors: Pian Anaïk
Published: October 2021

Depuis les années 1990, de nombreux travaux socio-anthropologiques se sont intéressés aux conditions de production du récit de l’asile. Toutefois, dans la littérature francophone en particulier, ils ont laissé dans l’ombre la question de l’interprétariat alors même que, dans l’asile, les manières de se raconter sont traversées par des enjeux socio-langagiers et politiques très forts. En croisant les apports de la sociologie des institutions, de la sociologie interactionniste et de l’anthropologie des pratiques langagières, l’article éclaire, à partir d’un terrain ethnographique, les conditions de production sociale de l’interprétariat dans le cadre contraignant de la Cour nationale du droit d’asile (CNDA). Au-delà du caractère très normé des audiences, il donne à voir comment se construisent les pratiques langagières des interprètes dans le contexte du jugement de l’asile. Ce faisant, la focale sur l’interprétariat permet de relier deux volets souvent appréhendés de manière séparée dans les travaux sur l’asile : celui de la construction du récit et celui du fonctionnement des institutions dédiées.
On the eccentric connectivity coindex in graphs

Published: October 2021

The well-studied eccentric connectivity index directly consider the contribution of all edges in a graph. By considering the total eccentricity sum of all non-adjacent vertex, Hua et al. proposed a new topological index, namely, eccentric connectivity coindex of a connected graph. The eccentric connectivity coindex of a connected graph $ G $ is defined as

   \begin{document}$ \overline{\xi}^{c}(G) = \sum\limits_{uv\notin E(G)} (\varepsilon_{G}(u)+\varepsilon_{G}(v)). $\end{document}

Where $ \varepsilon_{G}(u) $ (resp. $ \varepsilon_{G}(v) $) is the eccentricity of the vertex $ u $ (resp. $ v $). In this paper, some extremal problems on the $ \overline{\xi}^{c} $ of graphs with given parameters are considered. We present the sharp lower bounds on $ \overline{\xi}^{c} $ for general connecteds graphs. We determine the smallest eccentric connectivity coindex of cacti of given order and cycles. Also, we characterize the graph with minimum and maximum eccentric connectivity coindex among all the trees with given order and diameter. Additionally, we determine the smallest eccentric connectivity coindex of unicyclic graphs with given order and diameter and the corresponding extremal graph is characterized as well.

In this paper, in order to explore the inhibition mechanism of algicidal bacteria on algae, we constructed an aquatic amensalism model with non-selective harvesting and Allee effect. Mathematical works mainly gave some critical conditions to guarantee the existence and stability of equilibrium points, and derived some threshold conditions for saddle-node bifurcation and transcritical bifurcation. Numerical simulation works mainly revealed that non-selective harvesting played an important role in amensalism dynamic relationship. Meanwhile, we proposed some biological explanations for transcritical bifurcation and saddle-node bifurcation from the aspect of algicidal bacteria controlling algae. Finally, all these results were expected to be useful in studying dynamical behaviors of aquatic amensalism ecosystems and biological algae controlling technology.
