Impact of Flow Variation on Hydropower Projects in Budhigandaki River Basin of Nepal
Authors: Marahatta Suresh , Devkota Laxmi Prasad , Aryal Deepak
Published: June 2021

Daily flow data from 1964 to 2015 of Budhigandaki River at Arughat were analyzed to assess the impact of flow variation at different time scales to the run of the river (RoR) type of hydropower projects. The data show very high inter-annual variation in daily, monthly and seasonal flows. The long term annual average flow at Arughat was 160 m3/s and varies from 120 to 210 m3/s. The long-term averages of loss in flow for both dry and wet seasons based on daily flows for three design discharges (Q90, Q60 and Q40) were found to be respectively -0.72, -1.76 and -1.54 m3/s for dry season and 0.0, -0.27 and -2.26 m3/s for wet season.  Although long-term average loss is small, uncertainty increases with the increase in design discharge. The long-term dry season power loss is about 3 % for the RoR projects of the basin however, its annual variation is large. There is a probability of losing the quantum of energy generation by nearly 40% in some years and gaining by about 30 % in some other years in dry season. The impact of flow variation on power production was negative in both dry and wet seasons for RoR projects of Budhigandaki basin. This study concludes that uncertainty arising from daily flow variation should be assessed while estimating energy generation in hydropower projects. Intra-annual flow variation is, thus, to be taken into consideration while calculating the power generated by the RoR plants; and it should be reflected in power purchase agreement.
Four Flavours of Customers: A dual-system perspective on self-service technology use
Authors: Penttinen Esko , Rinta-Kahila Tapani
Published: June 2021

Self-service technologies (SSTs) increasingly permeate retail spaces. To make their SST investments worthwhile, retailers need to turn enough customers into SST users. Previous research has uncovered the significance of habitual behaviour stemming from prior experience and situational factors from the environment on SST use. However, consumers are likely to vary regarding the extent they are driven by either habit or situational factors, suggesting that different types of consumers might exist in this regard. In this paper, we probe these consumer types in a real-life choice situation by studying the choice of selecting a checkout option (either staffed or self-checkout). We conduct a field study employing mixed qualitative methods by observing and interviewing customers checking out from retail stores. We discover four distinct customer types regarding the extent of reflexive (automatic) and reflective (deliberate) processing they use in their checkout selection: habitual traditional checkout users, habitual SCO users, situational users, and drifting users. We discuss the implications of our findings by linking the cognitive processing styles to the different stages of technology acceptance. Our main contribution lies in the development of a typology of consumers based on their selection between SST and human-delivered service.

Published: June 2021

O endividamento revela-se como um fenômeno multifacetado, cujas repercussões extrapolam a esfera econômica, sendo responsável por forjar as subjetividades individuais, os modos de expressão e as práticas cotidianas dos sujeitos. Destarte, o presente estudo teve como objetivo apreender a representação social do constructo do endividamento para consumidores pertencentes à baixa renda, buscando identificar os significados que a ela subjazem. Para a obtenção dos propósitos dessa pesquisa, foram realizadas 194 entrevistas estruturadas de curta duração, analisadas a partir da técnica de evocação livres de palavras e do método Alceste mediante o uso do software IRAMUTEQ. Como resultado, verificou-se que o endividamento se revela enquanto fenômeno multifacetado com uma multiplicidade de atributos que concorrem à representação do seu conceito, transcendendo a compreensão puramente racionalista da lógica econômico-financeiro. Sucintamente, os sujeitos estruturam sua representação do endividamento em dois polos organizadores principais, expressados através de um elemento estrutural – a qual possui origem no arranjo socioeconômico geral – e de seu inter-relacionamento ao contexto individual. Nesse sentido, o fenômeno do endividamento apresenta repercussões subjetivas aos sujeitos, refletidas na organização das práticas do cotidiano, gerando, assim, um conjunto de obrigações financeiras individualizantes que resultam, sobretudo, em consequências emocionais prejudiciais aos mais pobres.
Primary microcystic/reticular schwannoma of the frontal bone: illustrative case
Authors: Zhao Xuemiao , Zhou Xinmu , Chen Xiao , Pan Junqiao , Li Bingrong
Published: June 2021

BACKGROUND

To the best of the authors’ knowledge, this is the first case of microcystic/reticular schwannoma arising in the frontal bone.

OBSERVATIONS

An 18-year-old man presented to the authors’ orthopedic clinic with a complaint of a progressively enlarging, painless mass in the frontal bone. It showed significant hyperintensity on T2-weighted imaging with progressive enhancement. Computed tomography combined with three-dimensional reconstruction showed expansive bone destruction with a soft tissue mass in the left side of the frontal bone, without calcification inside or a sclerotic margin around it. The mass was a microcystic/reticular schwannoma as confirmed by surgical pathology.

LESSONS

The authors report a rare case of a microcystic/reticular schwannoma arising in the frontal bone, with relatively comprehensive imaging data that enabled them to learn more about this tumor.
Conservative rehabilitation for a patient presenting with severe orthostatic hypotension after surgical management of brainstem tumor: illustrative case
Authors: Nagumo Misato , Tashiro Syoichi , Hijikata Nanako , Ishikawa Aiko , Akiyama Takenori , Tsuji Tetsuya
Published: June 2021

BACKGROUND

Blood pressure (BP) dysregulation is frequently observed in patients after surgical management of brainstem lesions; however, there has been no standard rehabilitation. Considering the conflicting risks for hypoperfusion and disuse syndrome in these patients, a safe and effective rehabilitative strategy is warranted.

OBSERVATIONS

A 50-year-old man who had undergone craniotomy for resection of a recurrent dorsal medullary epidermoid cyst developed persistent orthostatic hypotension. It was resistant to physical exercise, pharmacological therapy, abdominal binders, and compression stockings; therefore, it inhibited postoperative rehabilitation. Although the responsible lesion was not clearly visible on the postoperative image, accompanying symptoms, including segmental sensory impairment, implied an improvement in BP control. Although there was a trade-off between the risk of developing disuse syndrome and a delay in functional recovery, the authors decided to continue a conservative rehabilitation strategy rather than increasing the workload. The patient’s BP control was gradually restored by the seventh postoperative week, and the authors proceeded with basic activity training.

LESSONS

A conservative prognostic prediction-based rehabilitation strategy was applied in this case. The precise evaluation of the accompanying neurological symptoms was helpful in deciding the treatment regimen. The conflicting risks for hypoperfusion and disuse syndrome in such cases must be considered.
Decision-making for decompressive craniectomy in traumatic brain injury aided by multimodality monitoring: illustrative case
Authors: Robinson Myranda B. , Shin Peter , Alunday Robert , Cole Chad , Torbey Michel T. , Carlson Andrew P.
Published: June 2021

BACKGROUND

Severe traumatic brain injury (TBI) requires individualized, physiology-based management to avoid secondary brain injury. Recent improvements in quantitative assessments of metabolism, oxygenation, and subtle examination changes may potentially allow for more targeted, rational approaches beyond simple intracranial pressure (ICP)-based management. The authors present a case in which multimodality monitoring assisted in decision-making for decompressive craniectomy.

OBSERVATIONS

This patient sustained a severe TBI without mass lesion and was monitored with a multimodality approach. Although imaging did not seem grossly worrisome, ICP, pressure reactivity, brain tissue oxygenation, and pupillary response all began worsening, pushing toward decompressive craniectomy. All parameters normalized after decompression, and the patient had a satisfactory clinical outcome.

LESSONS

Given recent conflicting randomized trials on the utility of decompressive craniectomy in severe TBI, precision, physiology-based approaches may offer an improved strategy to determine who is most likely to benefit from aggressive treatment. Trials are underway to test components of these strategies.
Culture of silence: A brief on reproductive health of adolescents and youth in Pakistan
Authors: Sultana Munawar
Published: June 2021

Previous research on the reproductive health of adolescents and youth in Pakistan has not addressed the diversity of adolescent experiences based on social status, residence, and gender. To understand the transition from adolescence to adulthood more fully, it is important to assess social, economic, and cultural aspects of that transition. This brief presents the experience of married and unmarried young people (males and females) from different social strata and residence regarding their own attitudes and expectations about reproductive health. More young people aged 15–24 live in Pakistan now than at any other time in its history—an estimated 36 million in 2004. Recognizing the dearth of information on this large group of young people, the Population Council undertook a nationally representative survey from October 2001 to March 2002. The analysis presented here comes from Adolescents and Youth in Pakistan 2001–02: A Nationally Representative Survey. The survey sought information from youth aged 15–24, responsible adults in the household, and other community members in 254 communities. A total of 6,585 households were visited and 8,074 young people were interviewed.

Family plays a critical role in young people’s lives and is key in determining the conditions under which young people make important transitions to adulthood. This brief examines the impact of family-level poverty on the educational attainment, economic activity, and marriage patterns of Pakistani youth, and shows how strongly socioeconomic status shapes the lives of future generations. More young people aged 15–24 live in Pakistan now than at any other time in its history—an estimated 36 million in 2004. Recognizing the dearth of information on the situation of this large group of young people, the Population Council undertook a nationally representative survey from October 2001 to March 2002. The analysis presented in this brief comes from Adolescents and Youth in Pakistan 2001–02: A Nationally Representative Survey—the largest such survey focusing on young people. The survey sought information from youth aged 15–24, responsible adults in the household, and other community members in 254 communities. A total of 6,585 households were visited and 8,074 young people were interviewed.
Medicine on the Edge of the Habsburg Territories
Authors: Hirsch Sandra
Published: June 2021

Designed as a defensive system against the Ottoman Empire, the Austrian military border was doubled by a sanitary cordon, which served as a defense shield against epidemics. In order for this system to function adequately, the border patrol troops that served the House of Habsburg also needed protection against the diseases that threatened the empire. The present study brings into discussion the health problems that border guards from the Banat region experienced, a topic that remains largely unaddressed in the existing literature. By building on original archival research and the specialized work of the epoch, this article traces the main conditions, the means of tackling diseases, the remedies that were specifically local or those found within the European repertoire. It also sheds light on the support that the administrative apparatus offered to the troops, namely medical care in its material form (hospitals, quarantines, pharmacies, medicine, monetary assistance) and human form (the personnel hired at the borders: military doctors, surgeons, midwives, veterinarians). This article concludes that the entire correspondence from the center directed at the local authorities in Banat and vice versa reflects in a unique and subtle way the level of medical knowledge of the time.

Published: June 2021

Study of the processes of solid-phase reduction of iron from oxides using coals as reducing agents and the development of energy-efficient technologies for the production and use of metallized materials from concentrates obtained as a result of hydrometallurgical enrichment is an actual scientific direction in ferrous metallurgy. Theoretical studies of the processes of solidphase reduction of iron from iron-containing concentrate obtained as a result of hydrometallurgical enrichment of ferromanganese and polymetallic manganese-containing ores, by coals grades D (long-flame) and 2B (brown) were carried out by the method of thermodynamic simulation using the “Terra” software complex. The experimental study of the process of solid-phase reduction of iron from experimental mixtures was carried out in a muffle furnace SNOL 4/900 and in a resistance furnace with a graphite tubular heater (Tamman furnace). The influence of the composition and volume of gas phase, formed as a result of volatile components emission in the process of coals of two grades heating at 373–1873 K obtained, optimal temperature and consumption of coals defined, which ensure complete reducing of iron from iron-containing concentrate, compositions as well as volumes of gas phase. The influence of temperature of the isothermal exposure on the rate and degree of solid-phase reduction of iron from iron ore oxides was experimentally determined when using coals of different process grades and coke fines as reducing agents. Empirical equations of reduction degree versus time of isothermal exposure for different metallization temperatures were obtained. It is shown that the change in the degree of recovery on temperature with high accuracy was described by a linear dependence, and the change in the recovery rate on the temperature – by a power dependence. Conditions of effective metallization were determined when using iron concentrate and coals of different process grades for production of spongy metallized materials with content of Femet more than 80%, and 1.5–2.5 % C, 0.1 % S, 0.02 % P. As a result of thermodynamic simulation and experimental study of the process of iron reduction from iron concentrate, optimal consumption of coal of grades D and 2Б at temperature 1473K was determined. It was established that the best reducing agent with a minimum specific consumption is long-flame coal grade D. It was found that with an excess of reducing agent, it is possible to achieve almost complete extraction of iron from the concentrate, at the level of 98–99%.

Authors: Rakhmanov S. R.
Published: June 2021

Elimination of nonstable deformed state of main drive systems of Pilger pipe cold rolling (PCR) mills with distributed parameters is often stipulated by dynamics stabilization of multi-mass in-line mechanical system. Increase of productivity and optimal conditions of PCR mills loading is reached by dynamic synthesis of base mechanisms. Results of study of force line dynamics of PCR mill with embedded doubled elastic clutch or torsion damper presented. A nonlinear dynamic model of the main force line of a PCR mill with compensating doubled elastic clutch created. A solution of the dynamic synthesis of PCR mill force line task was obtained by nonlinear programming application. To decrease dynamic loads level, an optimal synthesis of the damper system of PCR mill force line was accomplished. A methodology of synthesis of parameters of nonlinear mechanical system with elastic clutch and damper proposed, as a mean to decrease destructive torsion oscillations in the main force line of PCR mill. Harmonic linearization of integral equations of mill main force line motion carried out, recorded by pulse-frequency characteristics. It was established that since the number of equations equals to the number of nonlinear effects of the mechanical system, the task solutions practically does not depend on the degree of freedom of the selected model. It was shown that the results obtained were adequate to the results of experimental studies of mill ХПТ 32 force line.
Perfection of Fe–C–Si–Мn–Сr–W–V system flux-cored wire composition for surfacing of hot rolling mill rollers by introducing titanium in it

Published: June 2021

Rollers for hot rolling mills are hardened by surfacing operation by flux-cored wire ПП-Нп-35В9Х3СФ due to GOST 26101–84. The deposited layer has a high resistivity against abrasion, but its thermal endurance is comparatively low, therefore rollers surfaced by this type of wire often failed because of formation of fire crack network and spalling. It was established that the structure nonuniformity of the deposited metal can be decreased by introducing of titanium into the flux-cored wire. The effect of introducing titanium into flux-cored wire of the Fe–C–Si–Мn–Сr–W–V system on the properties of the deposited layer has been studied. It was shown that metal structure with the addition of titanium represents martensite formed within the boundaries of the former austenite grain, a small amount of residual austenite in the form of separate areas and thin layers of δ-ferrite. The microstructure of the samples contains a carbide network. An increase in the titanium content in the deposited layer contributes to a decrease in the size of the martensite needles, as well as the size of the former austenite grain. The microstructure of the samples contains medium-acicular and fine-acicular martensite. The size of the martensite needles varies from 2 to 9 microns. It was established that introduction of titanium in the composition of the flux-cored wire in an amount of 0.02–0.13% increases the hardness of the deposited layer and reduces the abrasion of the samples.
Il diritto agrario europeo dopo Lisbona fra intervento e regolazione: i codici europei dell'agricoltura

Published: June 2021

Il lavoro indaga sugli esiti dell'entrata in vigore del Trattato di Lisbona, quanto alla disciplina dell'agricoltura europea. L'esame di una serie di riforme, anteriori e successive al Trattato di Lisbona, induce a concludere che la ri-nazionalizzazione e ri-localizzazione di alcune scelte di governo dell'economia agricola si è accompagnata ad una rinnovata articolazione del rapporto fra economia e diritto nella politica agricola comune. Il diritto in senso proprio, il diritto regolatorio, in contrapposizione con il diritto incentivante, caratterizza in misura crescente la legislazione di fonte europea in materia agricola. Le riforme della Pac di fine ed inizio secolo si sono così tradotte nella posizione di codici europei dell'agricoltura, dal codice dei regimi di sostegno al reddito [con il reg. (CE) n. 1782/2003, e poi con il reg. (CE) n. 73/2009], al codice dello sviluppo rurale [con il reg. (CE) n. 1257/2009, e poi con il reg. (CE) n. 1698/2005], al codice del mercato e della commercializzazione dei prodotti agricoli [reg. (CE) n. 1234/2007, c.d. regolamento unico Ocm]. Queste discipline di fonte europea dialogano con le discipline di fonte nazionale e compongono

Authors: Venturi Luca
Published: June 2021

L'articolo traccia uno spaccato degli strumenti repressivi utilizzabili - ed utilizzati nel Basso Molise - per cercare di contrastare in sede penale condotte di reato legate all'immigrazione clandestina, allo sfruttamento dei cittadini extracomunitari o comunque allo sfruttamento irregolare, come manovalanza, di cittadini stranieri impiegati nel territorio di competenza dell'ufficio dove per anni l'Autore ha lavorato e lavora. Ciò non senza alcune riflessioni in ordine all'adeguatezza - o forse sarebbe meglio dire all'inadeguatezza - del sistema repressivo che solo in astratto dovrebbe avere anche un effetto dissuasivo; il tutto con considerazioni legate anche ad esempi e casi concreti, anche assai tragici.

Published: June 2021

Tamil literature has many valuable thoughts that can help the human community to lead a successful and a happy life. Tamil literary works are abundantly available and searched on the World Wide Web (WWW), but the existing search systems follow a keyword-based match strategy which fails to satisfy the user needs. This necessitates the demand for a focused Information Retrieval System that semantically analyses the Tamil literary text which will eventually improve the search system performance. This paper proposes a novel Information Retrieval framework that uses discourse processing techniques which aids in semantic analysis and representation of the Tamil Literary text. The proposed framework has been tested using two ancient literary works, the Thirukkural and Naladiyar, which were written during 300 BCE. The Thirukkural comprises 1330 couplets, each 7 words long, while the Naladiyar consists of 400 quatrains, each 15 words long. The proposed system, tested with all the 1330 Thirukkural couplets and 400 Naladiyar quatrains, achieved a mean average precision (MAP) score of 89%. The performance of the proposed framework has been compared with Google Tamil search and a keyword-based search which is a substandard version of the proposed framework. Google Tamil search achieved a MAP score of 56% and keyword-based method achieved a MAP score of 62% which shows that the discourse processing techniques improves the search performance of an Information Retrieval system.
Dual Input Z-source Indirect Matrix Converter for Grid Connected Hybrid Renewable Energy Systems
Authors: Berkani Yazid , Taib Nabil
Published: June 2021

This paper presents a new converter topology for grid connected Hybrid Renewable Energy System (HRES). The proposed topology named Dual Input Z-source Indirect Matrix Converter (DIZIMC) consists of an Ultra Sparse Z-source Matrix Converter (USZMC) interfacing PV and Wind Turbine (WT) to the grid. The DC link of the proposed converter is replaced by Interconnection Sources System (ISS). The ISS operates according to whether the sources produce energy or not. It allows connecting the sources individually or simultaneously and even isolates them if necessary. In the other hand, the DIZIMC provides several advantages such as reduced number of IGBTs and compact size inherited from USZMC, the use of Z-sources instead of conventional DC/DC converters keep the matrix configuration of the global structure. The global model of the proposed system was tested by simulation under Matlab/Simpowersys environment. The obtained results show clearly freedom in connecting the operational sources, also a better quality of energy injected to the grid.

Küresel iklim değişimi kapsamında iklim parametreleri değişmekte, rüzgâr da bu
parametreler içerisinde, özellikle Türkiye literatüründe az çalışılan konular arasında yer
almaktadır. Dünya'da orta enlem karaları üzerinde rüzgâr hızı (RH) azalmaları, yüksek
enlemlerde karalarıyla okyanus ve deniz yüzeylerinde RH artışları görülmektedir.
Türkiye'de ham verilerle yapılan çalışmalarda genel olarak RH azalmaları, Doğu
Karadeniz-Güneydoğu çevresinde ise RH artışları belirlenmiştir. Bu çalışmada, verilerin
homojenlik testleri yapılmış, kırılma bulunan RH zaman serileri belli kurallara göre
düzeltilerek homojen hale getirilmiştir. Homojen verilerle Türkiye'deki RH rejimleri ile
eğilimler belirlenmiş, eğilimlerdeki benzerlik dönemleri göz önüne alınarak, RH eğilim
rejimleri ortaya koyulmuş, yıl içindeki rüzgâr genliklerindeki eğilimler incelenmiştir. Bu
analizlere göre, Türkiye'de tek zirveli, çift zirveli ve düzenli tip RH rejimleri bulunmaktadır.
Yıllık ortalama RH, Akdeniz Bölgesi ve Batı Karadeniz ile Marmara Bölgesi doğusunda
azalmaktadır. Kış mevsiminde Türkiye'nin batı yarısında, baharda İç Anadolu Bölgesi ve
çevresinde, yazın Güneydoğu Anadolu Bölgesi, Adana Bölümü doğu yarısı, Kuzeydoğu
Anadolu ve güney Ege kıyılarında, güz mevsiminde ise Türkiye genelinde RH azalmaları
belirlenmiştir. Aylık RH eğilimlerine göre Türkiye'de, baharda azalan, baharda artan,
güzde artan, sıcak dönemde artan, soğuk dönemde artan, baharda-güzde artan ve
yılboyu azalan tip olmak üzere 7 farklı RH eğilim rejimi bulunmaktadır. Ayrıca Türkiye
genelinde, yıl içindeki RH genlikleri azalmaktadır.

Introduction: Excessive alcohol consumption has been recognized as a threat to the national security of the Russian Federation. Challenges in studying volume and pattern of alcohol consumption, registration and identification of cases of alcohol-associated deaths are among the reasons for insufficient data for prevention of alcohol-associated deaths. Decision-makers should be aware of alcohol-attributable mortality in their federal subjects to develop region-specific prevention programs. Aim: To study temporal trends in blood (urine, muscle) alcohol concentration using the data from forensic autopsy protocols from 2007-2018 in the Sakha (Yakuta) Republic, North-Eastern Russia. Methods: Data on blood (urine, muscle) alcohol concentration (BAC) were obtained for all autopsied individuals in 2007-2018 in the Sakha Republic using medical documentation from the Republican Forensic Bureau. Temporal trends in average concentrations were assessed using Jonkheer-Terpstra tests. Ordinal variables were studied with ordinal regression models. Poisson models were applied for the analysis of time trends for binomial outcomes. Results: The proportion of individuals with BAC between 3.0 and 5.0 % and more than 5.0 %) decreased 25.3 % to 18.0 % (p < 0.0001). Decreasing trends of average BAC in both men and women were observed. The proportion of deceased with BAC > 0.3 % decreased on average by 34.8 % being more pronounced among the women. Conclusions: Our finding suggest a gradual decrease in average blood alcohol concentrations as well as in the proportion of deceased with high and lethal BAC in autopsied individuals in the Sakha (Yakutia) Republic over the study period. More pronounced decrease was observed among the women. Our findings should be generalized and interpreted with due caution taking into account the limitations of the forensic autopsy study design.

Purpose: This study aims to investigate the safety, efficacy and feasibility of sutureless trabeculectomy using a porous collagen matrix that contains a connected porous structure (Ologen) in the control of intraocular pressure (IOP) in glaucoma patients .Methods: The study includes 25 eyes from 24 patients that met the inclusion criteria. All eyes underwent trabeculectomy with the Ologen implant that provides a space with a dynamic and physiological aqueous reservoir system. The operation was considered successful if IOP is <15 mmHg without need of IOP-lowering drops at 18 months of follow-up.Results: The target IOP was achieved in 21 out of the 25 eyes (84%), the remaining four eyes all had an IOP of 16 mmHg at 18 months. Short-term complications consisted of seven cases of bleb leakage treated with bandage contact lens and one case of mild choroidal effusion which resolved after observation alone.Conclusions: We can conclude that this technique can provide safety, effectiveness and short learning curve for ophthalmology trainees with lower incidence of perioperative and postoperative complications. Further studies may be required to prove stability and long-term efficacy in management of glaucoma patients.

The purpose of this article is to review the currently most widely used coronavirus disease 2019 vaccines, investigate their immunogenicity and efficacy data, and analyze the vaccine safety profiles that have been published, to date.
Different resiliencies in coral communities over ecological and geological time scales in American Samoa

In 1917, Alfred Mayor surveyed a 270 m transect on a reef flat on American Samoa. Eleven surveys were conducted on the transect from 1917 to 2019. The coral community on the reef crest was resilient over the century, occasionally being seriously damaged but always recovering rapidly. In contrast, the originally most dense coral community on the reef flat has been steadily deteriorating throughout the century. Resilience of coral communities in regions of high wave energy on the reef crests was associated with the important binding function of the crustose coralline alga (CCA) Porolithon onkodes. Successful coral recruits were found on CCA 94% of the time, yet living coral cover correlated negatively with CCA cover as they became alternative winners in competition. Mayor drilled a core from the transect on the surface to the basalt base of the reef 48 m below. Communities on Aua reef were dominated by scleractinians through the Holocene, while cores on another transect 2 km away showed the reef was occupied by alcyonaceans of the genus Sinularia, which built the massive reef with spiculite to the basalt base 37 m below. Despite periods of sea levels rising 9 to 15 times the rate of reef accretion, the reefs never drowned. The consistency of scleractinians on Aua reef and Sinularia on Utulei Reef 2 km away during the Holocene was because the shape of the bay allowed more water motion on Aua reef. After 10700 yr of reef building by octocorals, coastal construction terminated this spiculite-reef development.

Site fidelity is driven by predictable resource distributions in time and space. However, intrinsic factors related to an individual’s physiology and life-history traits can contribute to consistent foraging behaviour and movement patterns. Using 11 yr of continuous geolocation tracking data (fall 2008 to spring 2019), we investigated spatiotemporal consistency in non-breeding movements in a pelagic seabird population of black-legged kittiwakes Rissa tridactyla breeding in the High Arctic (Svalbard). Our objective was to assess the relative importance of spatial versus temporal repeatability behind inter-annual movement consistency during winter. Most kittiwakes used pelagic regions of the western North Atlantic. Winter site fidelity was high both within and across individuals and at meso (100-1000 km) and macro scales (>1000 km). Spatial consistency in non-breeding movement was higher within than among individuals, suggesting that site fidelity might emerge from individuals’ memory to return to locations with predictable resource availability. Consistency was also stronger in space than in time, suggesting that it was driven by consistent resource pulses that may vary in time more so than in space. Nonetheless, some individuals displayed more flexibility by adopting a strategy of itinerancy during winter, and the causes of this flexibility are unclear. Specialization for key wintering areas can indicate vulnerability to environmental perturbations, with winter survival and carry-over effects arising from winter conditions as potential drivers of population dynamics.
