Invert-emulsion drilling fluids for exposing Hamakin horizon of the Vostochno-Alinskoye oil and gas condensate field
Authors: Parfiryev V. A. , Vaganov Yu. V. , Zakirov N. N.
Published: July 2020

The article is devoted to an analysis of the oil well construction in the fields of the Talakan group of Eastern Siberia. The low quality of the construction of oil wells is explained based on geological structure of the reservoir and the conditions of its formation, particulary, the complications encountered during drilling are given. Based on the analysis, it was found that the use of traditional monosalt and salt-saturated drilling muds is not effective enough to simultaneously solve the problems of exposing intervals of salt deposits and high-quality primary exposing of reservoirs. Based on the literature data analysis and the experience of building the first exploratory wells in Eastern Siberia, the use of hydrocarbon-based flushing liquids is justified. As a result of theoretical and laboratory studies, the compositions of invert-emulsion drilling fluids are proposed of hydrocarbons, which are available in the conditions of fields in Eastern Siberia. The results of studies for determining the effect of flushing fluids on the reservoir properties of the V10 reservoir of the Vostochno-Alinskoye oil and gas condensate field showed that recovery of core permeability after exposure to hydrocarbon-based flushing liquid was on average 90 %, which is significantly higher compared to the effect of water-based drilling muds, where the recovery coefficient is 23 %.
Mathematical modeling of drives with tandem pneumatic cylinders
Authors: Zhurkin N. A , Donskoy A. S , Zharkovskiy A. A
Published: July 2020

The article considers the issue of mathematical modeling of tandem pneumatic cylinders. Despite the fact that the mathematical description of the operation of drives with single-piston cylinders is considered in sufficient detail in the literature, the peculiarity of drives with tandem cylinders, namely the commutation of their working cavities with pneumatic discharge and exhaust lines through one pneumatic distributor, requires the formation of a certain approach to their mathematical description. The paper shows two developed versions of mathematical models that describe their work. The first option involves taking into account some conventional intermediate chambers behind the pneumatic distributor, where the division and combination of compressed air flows between the pneumatic distributor and the working cavities of the tandem pneumatic cylinder takes place. The second one (the simplified) considers the working cavities of the cylinder independently. Comparison of the results of mathematical modeling for two options showed a fairly significant difference in the time of movement of the piston of the cylinder. Moreover, it can be seen from the results that this difference is primarily associated with the distribution of air pressure between the intermediate chambers and the working cavities of the cylinder. According to the obtained results, it follows that when developing pneumatic drives and pneumatic actuators with tandem pneumatic cylinders, despite the complexity of the calculation, it is preferable to take into account in the mathematical model the intermediate chambers, where the division and combination of compressed air flows takes place. The developed model can be used in the design of pneumatic drives of various machines and mechanisms that use tandem pneumatic cylinders. This modeling approach can be used in the study of other multi-piston pneumatic engines or drives with several engines controlled by a single pneumatic switchgear.

Published: July 2020

The article considers a single-mass vibration protection system with an executive electromechanical device. The relevance of the research direction and the current state of its knowledge are presented. It is proved that in comparison with the controlled elements of viscous resistance, the controlled stiffeners provide the best quality of vibration protection. The prospects for the use of controlled electromechanical stiffeners are emphasized. The paper considers an actuator in the form of a linear DC motor. Examples of the use of active vibration protection systems with linear electric machines are given. In particular, an example of using as suspension of the vehicle is provided. The advantages and most significant drawbacks of such suspensions, which hinder their mass introduction, are indicated. The design scheme of a single-mass oscillatory system with parallel installation of a viscous friction element and a stiffener is presented. It is substantiated that, taking into account the accepted assumptions, the presented scheme is equivalent to vehicle suspensions. It is proposed to use a magnetorheological vibration damper as a controlled element of viscous resistance. The analysis of the state of the issue of active vibration protection systems with magnetorheological vibration dampers is given. The structure of closed by vibration acceleration of vibroprotection system protected object is developed. There are presented the mathematical models of its functionally necessary elements: vibration sensor, vibration protection system along the disturbance and control channel, linear DC motor. A technique for synthesizing a correction device that provides the desired resonant properties of a closed system is proposed. The results of simulation modeling of an active vibration protection system with a regulator synthesized according to the proposed technique and a regulator, the structure of which was obtained in the author’s previous works, are presented. Based on the obtained results, the conclusions on the presented materials are drawn and recommendations on the use of regulators are formulated.

Published: July 2020

Multifokaler/multizentrischer Brustkrebs (MF/MC) ist eine Krankheit, die viele Paradigmen in der aktuellen Praxis von Brustkrebs umfasst. Um Morbidität und Sterblichkeit zu bekämpfen, ist die beste Option eine rationale therapeutische Strategie, die mit einem klaren biologischen Verständnis von Multizentrizität und Multifokalität beginnen sollte, da dies bekannt ist, kann die richtige Behandlung befolgt werden. Unser Ziel war es, das Profil von Patienten mit multifokalem und multizentrischem Brustkrebs zu definieren und zu bewerten, ob es Meinungsverschiedenheiten zwischen Tumorherims in Bezug auf Hormonrezeptor und Her-2 gibt. Wir analysierten retrospektiv 89 Patienten mit multifokalem und multizentrischem invasivem Brustkrebs in zwei tertiären Einrichtungen im Nordosten Brasiliens, bewerteten Hormonrezeptoren, Her-2 und ki67 in jedem Tumorfokus von 25 dieser Patienten, wobei wir die Meinungsverschiedenheiten zwischen ihnen und Typ und histologische minologische Rand- und Bewertungsgrad, Lymphknotenmetastasierung und Entfernung und Alter hervorhoben. Von diesen Patienten stellten 9 % eine Heterogenität zwischen Tumor-Brennpunkten dar. Der Anteil der Metastasen im axillären Lymphknoten betrug 42% und nur 10% bei entfernter Metastasierung. 45 % der Frauen in der Studie hatten histologische Grade II oder III. Wir fanden eine Prävalenz von 40,5% der negativen Her-2 und 45% der positiven Östrogen-Rezeptor. Es gab keinen statistisch signifikanten Unterschied zwischen multifokalen und multizentraten Krebs. Wir kommen zu dem Schluss, dass MF/MC-Brustkrebs eine Heterogenität zwischen Tumorherims in Bezug auf biologische Parameter zeigt, was eine entscheidende Rolle bei der Entscheidungsfindung über die Behandlung und damit über Tumorrezidiv, Prognose und entfernte Metastasierung spielt.

Published: July 2020

Il cancro al seno multifocale/multicentro (MF/MC) è una malattia che comprende molti paradigmi nell'attuale pratica del cancro al seno. Per combattere la morbilità e la mortalità di questo l'opzione migliore è una strategia terapeutica razionale, che dovrebbe iniziare con una chiara comprensione biologica della multicentricità e della multifocalità, poiché questo è noto, il trattamento corretto può essere seguito. Il nostro obiettivo era quello di definire il profilo dei pazienti con cancro al seno multifocale e multicentro e valutare se c'è disaccordo tra i foci tumorali per quanto riguarda il recettore ormonale e Her-2. Abbiamo analizzato retrospettivamente 89 pazienti con carcinoma mammario invasivo multifocale e multicentrico in due istituzioni terziarie nel nord-est del Brasile, valutando il recettore ormonale, Her-2 e ki67 in ogni focus tumorale di 25 di questi pazienti, evidenziando il disaccordo o meno tra di loro, e il tipo e il grado istologico, la metastasi dei linfonodi e la distanza e l'età. Di questi pazienti, il 9% presentava eterogeneità tra i foci tumorali. La percentuale di metastasi nel linfonodo ascellare era del 42% e solo del 10% per metastasi distanti. Il 45% delle donne nello studio aveva un grado istologico II o III. Abbiamo trovato una prevalenza di 40.5% di Her-2 negativo e 45% del recettore estrogeno positivo. Non c'era alcuna differenza statisticamente significativa tra il cancro multifocale e quello multicentrico. Concludiamo che il cancro al seno MF/MC mostra eterogeneità tra i foci tumorali in relazione ai parametri biologici, che svolge un ruolo cruciale nel prendere decisioni sul trattamento e di conseguenza sulla ricorrenza del tumore, la prognosi e la metastasi lontana.

Striving to Include the Excluded: A Case Study of a Special Education Initiative in Rural Honduras
Authors: Weissman Amanda Ketner
Published: July 2020

Despite the existence of national policies that allow students with disabilities to be taught in the general education setting in Honduras, there is a gap between policy and practice as students with disabilities experience worse learning outcomes than their peers. Previous work has shown that this is due in part to a lack of knowledge among general education teachers on how to work successfully with students with disabilities. This paper examines the effectiveness of an approach to address this in rural Honduras by providing professional development for fifteen in-service teachers in eight schools to impart techniques for working with 56 students with both learning and physical disabilities. Through a combination of surveys, interviews, and observations, results show benefits to the teachers

Published: July 2020

In this introduction to the special issue, we argue that inclusive education research should move beyond a traditional 'deficit' approach, rooted in special education. The articles contained in this special issue represent new ways of conceptualizing, researching, and exploring inclusivity in education. In sum, this special issue makes the case that inclusivity in education requires a complex systems approach of analysis and advocacy that recognizes multiple layers, actors, and sites. Specifically, any way of understanding inclusivity in education needs to foreground participants, practitioners, and end-users. We believe that new ways of researching and conceputalizing inclusivty in education also fits into current trends in international and comparative education.

The purpose of this study is to determine the perceptions of learning environment and achievement emotions of Turkish high school students in biology classes and to analyse the relationship among these variables. The sample consists of 2183 ninth, tenth and eleventh graders from 12 high schools in Turkey. Constructivist Learning Environment Scale and Biology Achievement Emotions Scale were, respectively used to identify the perceptions of constructivist learning environment and biology achievement emotions of the participant students. The results of the canonical analysis showed that when students perceive learning environment as comfortably to express their opinions about the lesson, they felt more joyful and proud and less anxious, angry, bored or hopeless. Moreover, a negative relationship was found between shared control and angry, anxiety and shame. The students who help their teacher to decide what activities or strategies organize his/her teaching, the less they will feel angry, anxious or shy.

In this present study, we have employed the techniques of exact quantization rule and ansatz solution method to obtain closed form expressions for the rotational-vibrational eigensolutions of the D-dimensional Schrödinger equation for the improved Wei potential, for cases of h′ ≠ 0 and h′ = 0. By using our derived energy equation and choosing arbitrary values of n and ℓ, we have computed the bound state rotational-vibrational energies of CO, H2 and LiH for various quantum states. The mean absolute percentage deviation (MAPD) and the Lippincott criterion ware used as a goodness-of-fit indices to compare our result with the Rydberg-Klein-Rees (RKR) and improved Tietz potential data in the literature. MAPD of 0.2862%, 0.2896% and 0.0662% relative to the RKR data for CO ware obtained. For the improved Wei and Morse potential, our computed energy eigenvalues for CO, H2 and LiH are in excellent agreement with existing results in the literature

Published: July 2020

This study assessed the inhibitory effects of the pod extract of Acacia nilotica against some pathogenic bacteria (Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococccus pyogenes). Fresh pods of Acacia nilotica were air-dried and then ground into fine powder. Thereafter, pod powder was extracted using ethanol and distilled water in the ratio 3 to 2 (v/v). The crude extract was concentrated in vacuo and lyophilized. Afterwards, screened for phytochemicals and tested for antibacterial activity against the bacterial isolates. Antibacterial potential, minimum inhibitory concentrations (MIC), and minimum bactericidal concentrations (MBC) of the extract were determined using standard microbiological method. Zone of inhibition shown by the crude extract at 50 mg/mL on the isolates ranged between 10 mm and 18 mm while MIC ranged between 1.56 mg/mL and 25 mg/mL. Minimum bactericidal concentrations ranged between 3.13 mg/mL and 50.00 mg/mL. The phytochemical screening of the extract revealed the presence of tannins, alkaloids, flavonoids, saponins and cardiac glycosides. This study, therefore, showed that pod extract of Acacia nilotica exhibited appreciable inhibitory effects on the test isolates. Hence, there is need for in vivo studies to complement the present findings.

Termites are generally regarded as pests, although they have some beneficial roles to play in the ecosystem, particularly in the soil. This study was conducted between January 2018 and April 2018, to determine the effect of physico-chemical parametrs on abundance and diversity of termites and other arthropods in termite mounds in Uinversity of Uyo Community. Soil samples were randomly collected from six termite mounds from two sites for physiochemical parameters analysis and these were temperature, pH, moisture content, nitrogen, phosphorus, magnesium, copper, sodium, potassium, manganese and iron.. The termites and other arthropods were preserved in 70% ethanol. Temperature and moisture content, copper, sodium and iron were significant.  The results revealed that the physicochemical parameters affected the termite species abundance as station 1 (539) had relatively more of the termite species than station 2 (551), and also affected the diversity of the termites as station 1 (0.89) had relatively more diversity of the termites than station 2 (0.66). Also from the results, station 1 (2.06) had relatively more diversity of the other arthropod species identified in the study area than station 2 (1.59). Macrotermes bellicosus and Odontermes badius termite species were identified. Musca domestica, Anopheles gambiae, Lasius sp, Archispirostreptus sp, Camponotus sp, Missulena sp, Chorthippus sp, Acheta sp and Blatta orientalis were the other arthropods collected and identified. Macrotermes bellicosus (59.93 %; 63.52 %) was the most abundance and dorminant of the termite species identified in the study areas. Lasius sp (45; 25.93 %)

Published: July 2020

Mosquitoes constitute a serious Public Health menace, resulting in millions of death worldwide each year. Emergence of insecticide resistant strains of the mosquitoes poses a serious threat and hence calls for alternative control measures. This study assessed the larvicidal efficacy of the methanolic leaf extract of Calotropis procera against the 3rd instar larvae of Culex quinquefasciatus, after ten generations for 24 hours of exposure. Larvicidal activities of the leaf of the plant were studied on laboratory reared larvae of Culex quinquefasciatus at concentration ranges of 15 mg/L to 19 mg/L. The LC50 values were obtained from Probit analysis at 95% confidence limit (CL). Results of the study indicated that the LC50 values obtained from the parent generation (F0) to the tenth generation (F10) were; 15.79 mg/L, 16.58 mg/L, 17.29 mg/L, 18.07 mg/L, 18.95 mg/L, 19.99 mg/L, 20.65 mg/L, 21.18 mg/L, 22.80 mg/L, 25.16 mg/L and 32.98 mg/L respectively at 24hours. A higher efficacy of activity was exhibited by the extract at the parent generation (F0) with lowest LC50 of 15.97 mg/L at 24h.  The results of this research therefore underscore the efficacy of the plant and further suggest the use of the leaf extracts of Calotropis procera in the control of mosquito vectors and indirectly to the diseases they vectored.

Published: July 2020

In Nigeria most cities are water stressed, none of the cities are having regular water supply. Quality water for human consumption is a primary duty of the government but they have failed. Also, current cost of boreholes installation has increased beyond their capacity due to Naira devaluation in the world market. Water resources management requires constant monitoring in terms of its qualitative-quantitative values. This study presents potential impact of the Project Evaluation and Review Techniques (PERT) mathematical model software development for the supply of domestic well-water treatment plant. After testing software against the values then, the 37days calculated Expected Time (ET) is unreliable because the risk involved in this project is (100 – 34.23) % = 65.77 %. However, a new completing date can be predicted by PERT mathematical model for supply of domestic well-water treatment plant by varying probability of completion to predict new date of completing the plant. Therefore, concerning this research the Initial probability was moved from 34.23% to 90%. By interpolation with 37 days; the new acceptable date was 97.28 days. The risk involved now (100 – 90) % reduced to 10%, a very good comfortable zone for the project. This information has really helped in two ways: for easy computation and decision making in water supply scheme project. This result is useful in industrialization, individuals, housing estate, small and medium scale industries where quality domestic well-water for crops production is a necessity. Hence, it is recommended that, the developed mathematical models performed

DETERMINATION OF THE DELAY TIME OF THE BUS DEPARTURE FROM THE STOP POINT LOCATED NEAR A REGULATED CROSSROADS
Authors: Gorbachov P. , Makarichev O. , Kolii O. , Liubyi Y.
Published: July 2020

The article is devoted to solving scientific and applied problems of determining the rational location of stopping points at the entrance or exit from controlled intersections. Analysis of approaches and methods to the determination of rational location of stopping points showed that they are mostly based on the goals of minimizing the time for passenger transportation or maximizing the performance of transport systems functioning. With that, the question of determining the time of delay of vehicle departure from the stopping point bottleneck after the embarkation and disembarkation of passengers is paid very little attention to. Currently, there are only regression models available that cannot claim to be universal and their use in transport planning requires similar conditions of functioning with the object, where statistic data were collected.
The conducted analysis allowed determining the trend of basic research, namely, assessment of the influence of traffic flow parameters on the delay time of route transport departure from the stopping point bottleneck in the area adjacent to the controlled intersection. The process of delay occurrence at the exit of route transport from the stopping point bottleneck was formalized as the object of study thanks to which there was built an analytical model to determine the time of delay of route transport departure from the stopping point bottleneck.
There were investigated two options for placement of a stopping point at the entrance and exit from the intersection. According to the results of calculations, it was determined that the delay time of route transport departure from the stopping point was influenced by many factors, whose influence varies depending on the location of the stopping point at the entrance and exit from a controlled intersection.
By the results of researches one can be affirm that the most expedient is the placement of a stopping point at the minimum acceptable distance from the intersection, and it is recommended to locate a stopping point at a distance of 30 m at the entrance to the intersection.

A CROSS-AGE COMPARISON OF SCIENCE STUDENT TEACHERS’ CONCEPTUAL UNDERSTANDING OF SOIL EROSION
Authors: Er Nas Sibel , Çalık Muammer
Published: July 2020

The relevant literature has shown that student teachers hold alternative conceptions of soil erosion. Even though Turkish science student teachers are expected to teach the concept of ‘soil erosion’ in lower secondary schools (grades 5-8), none of the earlier studies have explored their conceptual growth and/or mental models throughout a 4-year undergraduate program. Indeed, science (student) teachers, who play a pivotal role in teaching the sustainability of soil as an environmental heritage, are able to transfer their environmental knowledge and mental models to younger generations. Therefore, the aim of this research was to elicit science student teachers’ (SSTs) understanding of soil erosion. In a cross-age comparison, the sample of the research was comprised of the first-year (n=54), second-year (n=62), third-year (n=60), and fourth-year of a four-year science education program (n=65), a total of 241 SSTs, enrolled at the Department of Science Education in Karadeniz Technical University in Turkey. A questionnaire with 4 open-ended questions and semi-structured interviews were used to collect data. The results indicated that the majority of the SSTs confused the concept of ‘soil erosion’ with the one ‘landslide’. For this reason, the current research suggests the development of analogies and computer simulations to overcome this confusion.
Keywords: conceptual understanding, cross-age, mental model, science student teacher, soil erosion.
THE LEVELS OF CRITICAL THINKING TENDENCIES IN ARCHITECTURAL EDUCATION
Authors: Kiliçaslan Hare
Published: July 2020

Students who receive architectural education are expected to be individuals who can think critically. For this reason, it becomes a necessity to cultivate creative individuals who are curious, inquiring and multi-faceted thinkers. The aim of this research was to determine the levels of tendency for critical thinking of first-year and fourth-year architecture students. The research sample consisted of 88 (54 females, 34 males) first-year and 83 (47 females, 36 males) fourth-year students who are studying at Karadeniz Technical University, Faculty of Architecture, Department of Architecture. The "California Critical Thinking Disposition Inventory (CCTDI)" was used as data collection tool in the research. In addition, information about the demographic characteristics of students were collected through the Personal Information Form. Findings of the research showed that there was no statistically significant difference between the GPAs and critical thinking tendency levels of the first-year and fourth-year students. It can be argued that all students need some guidance to attach importance on critical thinking starting from the first year of the program. Keywords: academic achievement, architectural students, critical thinking, critical thinking tendency.

Peran PKK adalah sebagai fasilitator dalam mendukung program-program pemerintah Kota Batam sudah berjalan cukup baik, meskipun ada beberapa masukan bahwa pemahaman masyarakat tentang pentingnya PKK dalam keluarga masih minim akan tetapi indikator lainnya seperti pendidikan,sikap dan sosial justru lebih berperan penting dan dominan dalam upaya peningkatan kesetaraan gender dalam lingkungan keluarga di Kota Batam khususnya Kecamatan Batu Aji. Sedangkan indikator pengalaman tidak terlalu berperan penting dan signifikan dalam upaya peningkatan kesetaraan gender dalam lingkungan keluarga keluarga dalam peran pemberdayaan PKK tersebut.

Partisipasi publik adalah konsekuensi dari kehidupan demokrasi. Namun pada prakteknya peran serta masyarakat dalam partisipasi publik sering kali diabaikan. Padahal dikatakan dalam perundang-undangan Negara wajib menyediakan ruang bagi peran serta publik terutama dalam proses penetapan kebijakan di era reformasi. Tulisan ini berusaha mendeskripsikan bagaimana pentingnya partisipasi publik, kendala-kendala yang dihadapi serta beberapa kemungkinan solusi untuk menyikapi kendala-kendala yang ada. Pendekatan utama yang dilakukan adalah studi dokumentasi serta hasil pengamatan penulis dilapangan. Adapun kesimpulan dari tulisan ini memperlihatkan bahwa partisipasi publik akan terwujud apabila ada kesepahaman antara pemerintah dan masyarakat tentang pentingnya hal ini serta meningkatnya kapasitas tidak hanya pemerintah tetapi juga masyarakat.
ANALISIS PENGARUH ETNISITAS DALAM PENGISIAN JABATAN STRUKTURAL DI PEMERINTAH KABUPATEN MUARO JAMBI: PASCA PILKADA 2017
Authors: Wahid Makmun , Haryadi Haryadi
Published: July 2020

Bermainnya politik etnis Jawa dalam perebutan jabatan politik dan birokrasi di Kabupaten Muaro Jambi melahirkan interaksi negatif bagi etnis Jawa dan etnis-etnis lain di Kabupaten Muaro Jambi. Apa yang dilakukan oleh etnis Jawa merupakan upaya mereka untuk menunjukkan dominasinya terhadap etnis lain di Kabupaten Muaro Jambi. Dimana  sebelumnya konsep putra daerah menjadi wacana bagi proses pengisian jabatan-jabatan tersebut. Penelitian ini menggunakan metode penelitian kualitatif, dengan pendekatan studi kasus dan teknik analisis data triangulasi. Dari metode yang digunakan tersebut diperoleh gambaran bagaimana kebangkitan politik etnis Jawa memberikan jalan bagi mereka untuk mendominasi jabatan politik dan jabatan birokrasi. Selain itu, pola dukungan pun akan terfragmentasi atas kesamaan identitas semata, terutama terkait kesamaan etnis. Tidak netralnya para birokrat dalam Pilkada menunjukkan bahwa partai politik di Indonesia tidak melembaga dengan baik.  Tidak heran, jika setelah Pilkada usai, hal itu memberikan dampak secara tidak langsung pada mekanisme rotasi, mutasi dan promosi jabatan-jabatan struktural di lingkup pemerintahan Kabupaten Muaro Jambi. Dimana penempatan orang yang dilakukan di dalam tubuh birokrasi akan didominasi oleh pengaruh etnis Jawa, yang kemudian pelan-pelan ‘menyingkirkan’ etnis lainnya. Jelasnya, mekanisme seperti itu cenderung lebih mengedepankan pendekatan patron klien ketimbang mengutamakan kinerja dari individu pejabat. Tulisan ini mengisyaratkan perlunya intervensi secara regulatif maupun tekhnis agar mekanisme pengisian jabatan publik di dalam birokrasi pasca Pilkada di Indonesia ke depan dapat menghasilkan elit-elit pemerintahan yang lebih berkualitas dan berintegritas. Penggunaan media digital baru menjadi tawaran bagi pembaharuan paradigma Birokrasi Pasca Pilkada.
Climate-associated trends and variability in ichthyoplankton phenology from the longest continuous larval fish time series on the east coast of the United States
Authors: Thaxton WC , Taylor JC , Asch RG
Published: July 2020

As the effects of climate change become more pronounced, variation in the direction and magnitude of shifts in species occurrence in space and time may disrupt interspecific interactions in ecological communities. In this study, we examined how the fall and winter ichthyoplankton community in the Newport River Estuary located inshore of Pamlico Sound in the southeastern United States has responded to environmental variability over the last 27 yr. We relate the timing of estuarine ingress of 10 larval fish species to changes in sea surface temperature (SST), the Atlantic Multidecadal Oscillation, the North Atlantic Oscillation, wind strength and phenology, and tidal height. We also examined whether any species exhibited trends in ingress phenology over the last 3 decades. Species varied in the magnitude of their responses to all of the environmental variables studied, but most shared a common direction of change. SST and northerly wind strength had the largest impact on estuarine ingress phenology, with most species ingressing earlier during warm years and delaying ingress during years with strong northerly winds. As SST warms in the coming decades, the average date of ingress of some species (Atlantic croaker Micropogonias undulatus, summer flounder Paralichthys dentatus, pinfish Lagodon rhomboides) is projected to advance on the order of weeks to months, assuming temperatures do not exceed a threshold at which species can no longer respond through changes in phenology. These shifts in ingress could affect larval survival and growth since environmental conditions in the estuarine and pelagic nursery habitats of fishes also vary seasonally.
