The Slug and Churn Turbulence Characteristics of Oil–Gas–Water Flows in a Vertical Small Pipe
Authors: Liu Weixin , Han Yunfeng , Wang Dayang , Zhao An , Jin Ningde
Published: August 2017

The intention of the present study was to investigate the slug and churn turbulence characteristics of a vertical upward oil–gas–water three-phase flow. We firstly carried out a vertical upward oil–gas–water three-phase flow experiment in a 20-mm inner diameter (ID) pipe to measure the fluctuating signals of a rotating electric field conductance sensor under different flow patterns. Afterwards, typical flow patterns were identified with the aid of the texture structures in a cross recurrence plot. Recurrence quantitative analysis and multi-scale cross entropy (MSCE) algorithms were applied to investigate the turbulence characteristics of slug and churn flows with the varying flow parameters. The results suggest that with cross nonlinear analysis, the underlying dynamic characteristics in the evolution from slug to churn flow can be well understood. The present study provides a novel perspective for the analysis of the spatial–temporal evolution instability and complexity in oil–gas–water three-phase flow.

Di-Wu-Yang-Gan Granules is a Traditional Chinese Medicine prescription used for the treatment of HBeAg-negative chronic hepatitis B patients in China. It consists of five commonly used Chinese herbs. However, the chemical constituents of the whole prescription had not been clarified yet. Hence, in this study, the chemical profiling of Di-Wu-Yang-Gan Granules was explored by ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry, which can provide accurate molecular weight within 5-ppm error and sufficient MS/MS fragment ions without the need for precursor ion selection. As a result, 116 compounds were identified, including lignans, triterpenesaponins, flavonoids, coumarins, iridoids, nortriterpenoids, phenolic acids, and sesquiterpenes. All compounds were further assigned to the individual herbs. In conclusion, this established method was reliable and effective for the separation and identification of the constituents in Di-Wu-Yang-Gan Granules. The findings are beneficial for quality control of the prescription during production and provide helpful chemical information for exploring its efficacy and the mechanism of action. The fragmentation regularity summarized in this study also provided important information for the rapid identification of the chemical composition in herbal medicines or their prescription.
Tracing Ingombe Ilede's trade connections
Authors: Killick David
Published: August 2017

McIntosh and Fagan (above) write that “For 45 years, Ingombe Ilede has been viewed as a key nexus linking the Copperbelt and Great Zimbabwe”. Some regional specialists have not believed this since the publication of Swan's (2007) important review of the sizes and shapes of prehistoric copper ingots found in modern Zimbabwe. Swan noted that both of the ingot moulds found at Great Zimbabwe (which have a clear stylistic connection to the Copperbelt) are of the earlier HIH style (ninth to fourteenth centuries AD; de Maret 1995; Nikis & Livingstone Smith in press). But neither the later HXR-style copper ingots (fourteenth to seventeenth centuries)—some of which were excavated at Ingombe Ilede—nor the moulds to make them have been found on a Zimbabwe tradition site. The distribution of HXR ingots within the modern nation of Zimbabwe is almost exclusively in the north, within the former territory of the Mutapa state (Swan 2007: fig. 2). The clear implication is that the HXR ingot style—and thus the elite burials at Ingombe Ilede—post-date the breakup of the state ruled from Great Zimbabwe, which gave birth to the Mutapa (northern) and Torwa (southern) states. The new radiocarbon dates by McIntosh and Fagan provide welcome confirmation of this inference.

Published: August 2017

After the Portuguese discovered the Cape Verde Islands in AD 1456 they divided its main island, Santiago, into two governing captaincies. The founding settlement in the south-west, Cidade Velha, soon became the Islands’ capital and a thriving trade centre; in contrast, that in the east, Alcatrazes, only lasted as an official seat from 1484–1516 and is held to have ‘failed’ (see Richter 2015).
Relocating Ingombe Ilede in the history of south-central Africa
Authors: McIntosh Susan Keech , Fagan Brian M.
Published: August 2017

We thank the four commentators for adding new dimensions and important data relevant to interpreting the new Ingombe Ilede dates. These contribute to the recent wave of reassessments and critiques of earlier interpretations and frameworks for the development of trade and complexity in southern Africa. Such reconsiderations are made possible by more sophisticated and precise radiocarbon dating, expanded investigation of both new and previously excavated sites, and by the use of chemical analyses to identify differently sourced groups of glass beads and metals (e.g. Pikirayi 2009; Robertshaw et al. 2010; Chirikure et al. 2013, 2014, 2016; Koleini et al. 2016).
City and wadi: exploring the environs of Jerash
Authors: Holdridge Genevieve , Kristiansen Søren M. , Lichtenberger Achim , Raja Rubina , Simpson Ian A.
Published: August 2017

Archaeological excavations of urban sites in the Mediterranean have a long history, but only recently are geoarchaeology-based landscape studies beginning to provide insight into the complex and dynamic relationships between cities and their hinterlands. Such studies are becoming increasingly important as archaeologists seek to understand how cities sustained themselves, demonstrating resilience to both external shocks and long-term environmental changes, and, conversely, how cities contributed to their own demise through the over-exploitation of environmental resources (Barthel & Isendahl 2013; Butzer et al. 2013; Kintigh et al. 2014; Nelson et al. 2016).

Archaeologists, it must ruefully be admitted, are often the beneficiaries of past societies’ disasters. How much more do we know of Pompeii and Herculaneum owing to the ash and pumice that engulfed them on that fatal day in AD 79? Yet the plaster casts of the victims remind us vividly of the cost in human lives, and recent analysis of the eruption has underlined what a terrifying experience that must have been. Similar evidence from other parts of the world is equally sobering: the iron-clad warrior who was overcome by pyroclastic flows at Kanai Higashiura in sixth-century Japan, for example, or the victims of the 1815 Tambora eruption, excavated at Pancasila in Indonesia.
New Book Chronicle
Authors: Witcher Robert
Published: August 2017

Reflecting on his motivations for writing a history of tomorrow, Yuval Noah Harari (2017: 68) observes that: “historians are asked to examine the actions of our ancestors so that we can repeat their wise decisions and avoid their mistakes. But it almost never works like that because the present is just too different from the past”. What then would Harari make of the new archaeology books reviewed in this instalment of NBC, concerned as they are with the present day and the future as much as they are with the past?
Khorbas: a Lower Palaeolithic site on Qeshm Island in the Persian Gulf
Authors: Ghasrian Sirvan Mohammadi
Published: August 2017

Despite the potential importance of southern Iran, and the Persian Gulf area in particular, for discussions on the dispersal of early hominins from Africa into Eurasia during the late Pliocene and early Pleistocene (Bar-Yosef & Belfer-Cohen 2001; Rose 2010), this area has remained almost unexplored until recently. Historically, Palaeolithic survey and excavations in Iran have mainly concentrated in western regions, especially the Zagros Mountains. As a result of recent studies, however, evidence for Palaeolithic sites in the southern regions of Iran, from Fars province to Qeshm Island, has greatly increased (Dashtizade 2009, 2010). Even with this improvement, no sites of Lower Palaeolithic date have yet been reported from the southern coastal areas on one of the proposed early hominin routes into Eurasia. As a result, it has been suggested that the few Lower Palaeolithic sites reported from other parts of Iran, especially in the west (e.g. Biglari & Shidrang 2006), were not populated from the south.
Ancient urbanism and complex societies in the Peruvian Desert: recent field research on the north and south coasts
Authors: Chicoine David
Published: August 2017

The two monographs under review here are both published by the University Press of Florida and both feature results of field research at two previously understudied sites on the north and south coasts of Peru. Based on descriptions of excavation contexts and the analysis of material remains, Melissa Vogel and Christina Conlee discuss the implications of El Purgatorio and La Tiza for understanding Casma urbanism and the development of complex societies in Nasca, respectively. Field and laboratory results are used to revisit perennial questions in Andean archaeology, including the origins of urbanism, human-environment interactions and the role of regional phenomena in the unfolding of local cultures. While both authors report on site-based projects, they structure their presentations differently. Conlee takes a more regional approach, synthesising previous research at the national, regional, local and site levels. Vogel takes a more site-centric approach, presenting a summary of the ancient city's organisation and examining its impact on regional developments.
Rethinking Ingombe Ilede and its hinterland
Authors: de Luna Kathryn M.
Published: August 2017

The late fifteenth- to early seventeenth-century dates reported by Susan McIntosh and Brian Fagan (above) for the richest burials at Ingombe Ilede challenge well-known narratives concerning trade and politics in greater Zambezia. For example, as the authors indicate, Ingombe Ilede now seems more an outcome of the destabilised politics of Great Zimbabwe than a cause of its demise. The role that the inhabitants of Ingombe Ilede played in the shifting competitions and alliances that characterised political and economic life in sixteenth-century Zambezia must now be addressed.
The glass beads from Ingombe Ilede
Authors: Robertshaw Peter , Wood Marilee
Published: August 2017

Analysis of glass beads from the Ingombe Ilede burials provides additional information that supports McIntosh and Fagan's new dating of burials 3 and 8, and that also clarifies the chronology of some of the other burials. Following an unsuccessful attempt to locate the Ingombe Ilede beads in the Livingstone Museum, we analysed beads from a card with samples of Ingombe Ilede beads that had been originally prepared by A.P. du Toit (1965), and later sold to MuseuMAfricA in Johannesburg (Figure 1). The beads were chemically analysed using LA-ICP-MS, as part of a larger project on ancient African glass bead chemistry (Robertshaw et al.2003). All analysed beads from burials 3 and 8 belong to the Khami series produced in India and traded into southern and south-central Africa from the mid fifteenth to mid seventeenth centuries. Some beads of an earlier type were present in other graves, and may have been kept as heirlooms.
Inquiry-Based Laboratory Experiences Using Ecosystem Microcosms
Authors: Sauterer Roger
Published: August 2017

Self-sustaining ecosystem microcosms, called ecosystem jars, can easily be collected from local ponds, streams, or lakes. Sealed and exposed to sunlight, these miniature ecosystems can sustain themselves for a decade or more. Unlike Winogradsky columns, ecosystem jars are optimized for protist, animal, and plant observations and experiments, and are not altered by addition of sulfur, carbon, or cellulose sources, more accurately representing natural ecosystems. Ecosystem jars can support a variety of inquiry-based experiments, including student-designed projects, from middle school to college levels. Students, with instructor assistance, formulate hypotheses, design experiments, observe and catalog organisms by microscopy, then record their data in tables and graphs and draw conclusions. Students present their data in a paper or poster format or as oral presentations to the class. Potential experiments include examining biotic changes over time, the effects of added pollutants or nutrients, biotic differences between watershed types, or seasonal changes in biota. These investigations not only provide students with cooperative learning, inquiry-based lab experiences, but also help them gain appreciation for the effects of pollution or nutrient runoff on ecosystems.
Socratic Seminar with Data: A Strategy to Support Student Discourse and Understanding
Authors: Griswold Joan , Shaw Loren , Munn Maureen
Published: August 2017

A Socratic seminar can be a powerful tool for increasing students’ ability to analyze and interpret data. Most commonly used for text-based discussion, we found that using Socratic seminar to engage students with data contributes to student understanding by allowing them to reason through and process complex information as a group. This approach also provides teachers with insights about student misconceptions and understanding of concepts by listening to the student-driven discussion. This article reports on Socratic seminar in the context of a high school type 2 diabetes curriculum that explores gene and environment interactions. A case study illustrates how Socratic seminar is applied in a classroom and how students engage with the process. General characteristics of Socratic seminar are discussed at the end of the article.
Beyond Merroir: The Okinawan Taste for Clams
Authors: Claus C. Anne
Published: August 2017

In southwestern Okinawa, local residents are reinvigorating their culinary heritage through a clam restoration project that began in 2009. The clams—giant clams, locally known as geera—have declined recently due to overharvesting on the reef. This article examines intersecting notions of heritage and community by contrasting the clam mariculture project with other heritage foods. The clams do not fit within prevalent images of Okinawan foods as nutritious and multicultural, and they are not among the Okinawan tastes that are celebrated outside of Okinawa. For islanders, the clams encapsulate place through their actual taste, the way they are acquired, and the social landscape of their consumption. Amidst the increasing influx of mainlanders in Okinawa, the clams become symbols that distinguish native islanders from newcomers.
The Transformation of Pig Feasts in Rural Northeast China
Authors: Veeck Ann , Yu Hongyan , Veeck Gregory
Published: August 2017

In many areas of rural China, pig feasts have long functioned as a vital ritual exchange among codependent farm households. Called sha nian zhu (roughly translated as “killing the year's pig”), the annual reciprocal feast has traditionally served to maintain community identities, provide aid, and strengthen social ties. Based on interviews with farm households in Zhenlai County in northern Jilin Province, we study the benefits that the annual pig feast provides communities. While some farmers believe this tradition will endure indefinitely, trends of urbanization and privatization—e.g., the peri-urban encroachment and confiscation of village land, the temporary and permanent migration of rural villagers to cities, the industrialization of pig production, and the year-round availability of meat—could lead to the transformation and marketization, or even abandonment, of this ancestral tradition.

Published: August 2017

Uno de los desafíos de la Odontología es la rehabilitación oral de los pacientes totalmente edéntulos con maxilares atróficos. Este caso clínico reporta un protocolo de tratamiento implantológico realizado en una paciente adulto mayor con maxilares edéntulos totales y con atrofia avanzada, en la cual se realizó una rehabilitación implanto-soportada e implanto-retenida consistente en una prótesis híbrida superior apoyada en seis implantes y una sobredentadura inferior retenida por una barra fija conectada a cuatro implantes, con un seguimiento total de un año, sin reportar complicaciones. Este caso nos otorga una evidencia de un protocolo implantológico y rehabilitador para pacientes con atrofias severas mejorando así la poca retención y estabilidad que presentan las prótesis convencionales en maxilares atróficos, además de mostrar los beneficios en cuanto a eficacia masticatoria y mejor calidad de vida en pacientes con este diagnóstico.
Estudio in vitro de la actividad antibacteriana del extracto de Erythroxylum coca sobre bacilos negro pigmentados
Authors: Enciso Deza Carmen , Ramos Perfecto Donald
Published: August 2017

Objetivo: Determinar si existe actividad antibacteriana del extracto de hoja de coca (Erythroxylum coca), sobre bacilos negro pigmentados (BNP). Materiales y método: Se emplearon dos pruebas: Test de Difusión en Agar y Dilución en medio líquido. Las cepas de BNP fueron aisladas de muestras tomadas de bolsas periodontales de pacientes con enfermedad periodontal atendidos en la Facultad de Odontología de la Universidad Nacional Mayor de San Marcos. El extracto hidroalcohólico de hoja de coca fue obtenido de la Empresa Nacional de la Coca (ENACO). Resultados: La primera prueba difusión en agar indicó sensibilidad nula (-) para la mayor parte de las concentraciones evaluadas, y sensibilidad límite (sensibilidad: +) para las concentración de 12,5% y 100%. Los resultados de la sensibilidad por dilución determinaron una concentración mínima del extracto capaz de inhibir el crecimiento de dicha bacteria, 100% (concentración mínima inhibitoria), y a las concentraciones de 12,5% y 6,25% se observa una repotenciación del efecto antibacteriano del extracto. Conclusiones: El extracto hidroalcohólico de hoja de coca, sí presenta una actividad antibacteriana frente a BNP, a las concentraciones de 100% y 12,5%.

‘Very Little Heroes’ History and Roots of the Eco-Village Movement
Authors: Farkas Judit
Published: August 2017

Although the ecovillage-movement is a relatively new phenomenon (it was first formalised in the 1990s), the initiatives, which aim to integrate, do have a much longer history. The author of this article has been studying ecovillages since 2008. As a cultural anthropologist, her focus lies in the socio-cultural dimensions of the ecovillage-movement. In the present paper the history and roots of the movement are covered by positioning eco-villages within both the history of the broader environmental movement and that of intentional communities; the international and Hungarian history of the ecovillage-movement is presented; and, last but not least, an interpretation is given of the Hungarian ecovillages in the context of rural migration processes. The picture drawn up here is not intended to be an exhaustive one, since the ecovillage-phenomenon can be presented from numerous different perspectives. Yet, the paper clearly demonstrates the multiple embeddedness of the movement, and provides an insight into the aspirations of ecovillage inhabitants and the current functioning of ecovillages.
Association between childhood and adult attention deficit hyperactivity disorder symptoms in Korean young adults with Internet addiction
Authors: Kim DongIll , Lee Deokjong , Lee Junghan , Namkoong Kee , Jung Young-Chul
Published: August 2017

Background and aims

Attention deficit hyperactivity disorder (ADHD) is one of the most common psychiatric comorbidities of Internet addiction (IA); however, the possible mechanisms that contribute to this high comorbidity are still under debate. This study aims to analyze these possible mechanisms by comparing the effect of IA severity and childhood ADHD on inattention, hyperactivity, and impulsivity in young adults with IA. We hypothesized that IA might have associations with ADHD-like cognitive and behavior symptoms aside from childhood ADHD.

Methods

Study participants consisted of 61 young male adults. Participants were administered a structured interview. The severity of IA, childhood and current ADHD symptoms, and psychiatry comorbid symptoms were assessed through self-rating scales. The associations between the severity of IA and ADHD symptoms were examined through hierarchical regression analyses.

Results

Hierarchical regression analyses showed that the severity of IA significantly predicted most dimensions of ADHD symptoms. By contrast, childhood ADHD predicted only one dimension.

Discussion

The high comorbidity of inattention and hyperactivity symptoms in IA should not solely be accounted by an independent ADHD disorder but should consider the possibility of cognitive symptoms related to IA. Functional and structural brain abnormalities associated with excessive and pathologic Internet usage might be related to these ADHD-like symptoms.

Conclusion

Inattention and hyperactivity in young adults with IA are more significantly associated with the severity of IA than that of childhood ADHD.

12 tips for developing trainee-led initiatives to promote recruitment to training in shortage specialties
Authors: Fisher James , Brock Peter , Saxton Nick , Garside Mark
Published: August 2017

This article was migrated. The article was marked as recommended. The healthcare needs of the global population are changing, leaving many medical specialties facing ballooning demand in the context of under-filled specialty training programmes. In this paper we draw on a synthesis of existing literature and our experiences of developing a series of initiatives to tackle the challenge of recruitment to specialty training in geriatric medicine in the UK. We propose a set of strategies that can contribute to the development and success of such initiatives and commend these to healthcare professionals, both junior and senior, who are working in so-called 'shortage' specialities facing recruitment challenges. A common theme throughout the twelve tips is the need to empower trainees to deliver such initiatives. Trainees' unique insight into training programmes, coupled with their burgeoning enthusiasm for their chosen specialty, ought to be harnessed, as it offers a ripe source of potential ideas and solutions to tackle recruitment problems.
Transcendence, historicity and temporality of being elderly: nursing reflection-using Heidegger
Authors: Guerrero-Castañeda Raúl Fernando , Prado Marta Lenise do , Kempfer Silvana Silveira , Vargas Maria Guadalupe Ojeda
Published: August 2017

ABSTRACT The objective is to reflect on historicity and temporality as paths for the transcendence of being elderly, based on the phenomenological concepts of Martin Heiddeger. A review of the concepts of transcendence, historicity and temporality was carried out in the work of Martín Heidegger, integrating them in the perspective of nursing for the elderly. The transcendence of the elderly adult is feasible by accessing the temporality of self in the path of its historicity to arrive at the understanding of itself that he has achieved: transcending, which is but a process of the Being itself. Being is time in itself existing in the world, existence given by the encounter of the past (to have been), present and future (becoming), the same encounter that determines the historicity of the Being. The encounter has been consummated and the Being is transcendence, with the understanding of the Being itself as a supreme point.
Scenario approximation in a phenomenological study in Mexico: experience report
Authors: Guerrero-Castañeda Raúl Fernando , Menezes Tânia Maria de Oliva , Vargas Ma. Guadalupe Ojeda
Published: August 2017

ABSTRACT Objective: To report our experience using scenario approximation in a phenomenological study of nursing in Mexico. Method: Experience report on scenario approximation to coexist with elderly in order to select the participants of a phenomenological study. Results: During a four-month period in 2016, visits were carried out two groups of elderly individuals where several activities were carried out. Coexistence with the elderly throughout accompaniment in the groups' activities together with joint dialogue allowed selection of those who corresponded to the characteristics of the study objective. Conclusion: Scenario approximation is necessary in phenomenological studies, not only for creating empathy among the participants but also for the researchers to immerse themselves in the phenomenon under study, as shown by the first approaches of the researcher.
Geriatric care: ways and means of providing comfort
Authors: Ribeiro Patricia Cruz Pontifice Sousa Valente , Marques Rita Margarida Dourado , Ribeiro Marta Pontifice
Published: August 2017

ABSTRACT Objective: To know the ways and means of comfort perceived by the older adults hospitalized in a medical service. Method: Ethnographic study with a qualitative approach. We conducted semi-structured interviews with 22 older adults and participant observation of care situations. Results: The ways and means of providing comfort are centered on strategies for promoting care mobilized by nurses and recognized by patients(clarifying/informing, positive interaction/communication, music therapy, touch, smile, unconditional presence, empathy/proximity relationship, integrating the older adult or the family as partner in the care, relief of discomfort through massage/mobilization/therapy) and on particular moments of comfort (the first contact, the moment of personal hygiene, and the visit of the family), which constitute the foundation of care/comfort. Final considerations: Geriatric care is built on the relationship that is established and complete with meaning, and is based on the meeting/interaction between the actors under the influence of the context in which they are inserted. The different ways and means of providing comfort aim to facilitate/increase care, relieve discomfort and/or invest in potential comfort.

Method: Controlled clinical trial. The HE Program consisted of 10 sessions with group dynamics, including orientations on disease prevention and cognitive stimulation exercises, lasting four months. Intervention Group (IG) n=13; and Control Group (CG) n=15. All were assessed at the start and end of the study, using Addenbrook´s Cognitive Examination-Revised (ACE-R), Beck Depression and Anxiety Inventory (BDI/BAI) and Functional Independence Measure (FIM). Results: Significant improvements were observed for the IG when comparing the total ACE-R score (p=0.001) and memory domain (p=0.011) before and after the intervention. For the CG, improvement was found in the memory domain only (p=0.027). Conclusion: a HE intervention program benefits the improvement in cognitive performance, particularly the memory of adults and active elderly who participated in a U3A.

ABSTRACT Objective: To analyze the relationship between spiritual well-being, sociodemographic, economic, religious, and health variables and the quality of life of older adults undergoing hemodialysis. Method: This was a cross-sectional and correlational study conducted with 169 older adults undergoing hemodialysis. The researchers conducted interviews to collect sociodemographic, economic, religious, and health data and applied the Spiritual Well-Being Scale (SWBS) and the WHO quality of life assessment (WHOQOL-BREF and WHOQOL-OLD). Results: Most of the older adults attained a moderate level of total spiritual well-being (SWB). In terms of QOL, the psychological domain (66.8; sd=13.9) and social relationships domain (66.8; sd=15.1) presented the highest mean scores. The WHOQOL-BREF domains were positively correlated with the SWB scale, with statistical significance among all domains and subscales except the environmental domain. Conclusion: The QOL of older adults was associated with the construct of SWB, either positively or negatively.

ABSTRACT Objectives: To validate the content of a fall management risk protocol in long-term institutions for elderly people. Methods: Methodological, quanti-qualitative study using the Delphi technique. The tool, based on the literature, was sent electronically to obtain consensus among the 14 experts that meet the defined inclusion criteria. Results: The 27 indicators of the protocol are organized in three dimensions: prepare for the institutionalization (IRA=.88); manage the risk of falls throughout the institutionalization (IRA=.9); and lead the communication and formation (IRA=1), with a CVI=.91. Two rounds were performed to get a consensus superior to 80% in every item. Conclusion: The values obtained in the reliability test (>0.8) show that the protocol can be used to meet the intended goal. The next step is the clinic validation of the protocol with residents of long-term care institutions for elderly people.

ABSTRACT Objective: To analyze the police reports filed by older adults who suffered abuse in order to identify the socio-demographic characteristics of victims and aggressors, type of violence, location, as well as to compare rates in three Brazilian cities in the period from 2009 to 2013. Method: Ecological study, in which 2,612 police reports registered in Police Stations were analyzed. An instrument was used to obtain data from the victim, the aggressor and the type of violence. Results: Psychological abuse predominated and most cases occurred in the older adults own home. In the cities of Ribeirão Preto and João Pessoa, the older adults presented similar rates for both gender. Regarding the standardized rates, in João Pessoa, there was a rise of this type of abuse in the two first years, and later there was a certain stability. In the city of Teresina, there was an increase, also observed in the city of Ribeirão Preto in the three first years, followed by a decrease. Conclusion: Older adults abuse is a cultural phenomenon difficult to be reported by them, since it occurs in the family context.

ABSTRACT Objective: To identify the main nursing diagnoses (NSs) in older adult patients under hemodialysis treatment. Method: Exploratory research using case studies in data collection performed by interview and physical examination of older adults, in the first semester of 2016. Were included twenty-eight older adults undergoing chronic hemodialysis treatment who met the selection criteria. The analysis followed two steps (RISNER, 1990): Phase I - Data analysis and synthesis; and Phase II - Establishment of nursing diagnoses using the taxonomy of NANDA-I (2015). Results: The total of NSs was 110, averaging 3.9 per patient. It was listed seven different NSs, and both the Risk of infection and the Volume of excessive liquids appeared on all patients (28; 100%), and risk of electrolyte imbalance, in 26 (96.8%) older adults, being considered as main NSs. Conclusion: Such results can help systematize the care of older people who are undergoing hemodialysis treatment.

ABSTRACT The production of biofuels from native Amazonian palm trees, belonging to the family of Arecaceae, like Attalea maripa (Aubl) Mart. (Maripa palm), are objects of studies of alternative energy sources for the biofuels production. Thus, the aim of this research was to evaluate the spatial dynamics of agronomic variables of Maripa palm crop production associated with the characteristics of the sampling sites in a spontaneous growth area in the Low Tocantins region. 100 palms of A. maripa were selected, of spontaneous growth and in production phase, on a 10 ha area in the municipality of Cametá / PA, in which the morpho-agronomical variables were collected (MIN, FIN, ABN, LN, DBH, AWAB and AFW), from January 2014 to June 2014. The semivariograms were produced for each variable, which presented a spatial dependence range of 75 meters to MIN, FIN, AWAB and AFW, 80 meters to LN and DBH and 98 meters to ABN. The area of reach found was 17,671.5 m² for MIN, FIN, AWAB and AFW variables, 20,106.2 m² for LN and DBH and 30,171.9 m² for ABN. The data of the variables were adjusted to the spherical model presenting determination coefficient (R²) that ranged from 0.57 to 0.99. The spatial dependence index (SDI) for MIN and FIN variables was 0.49 and 0.31, respectively, indicating moderate spatial dependence. For ABN, LN, DBH and AWAB variables ranged from 0.17 to 0.22, resulting in poor spatial dependence. The AFW variable presented SDI of 0.77. For the visual analysis of the spatial distribution of the studied variables, kriging maps were created.

ABSTRACT With the advent of black sigatoka in commercial banana crops in the “Vale do Ribeira” region, state of São Paulo, the monitoring the severity and chemical control of the disease in susceptible varieties have become more frequent in order to avoid leaf loss. This study simulated the effect of defoliation caused by the disease on the yield and quality of ‘Prata Comum’ banana fruits, depending on the formation period and fruit position in the bunch. The experimental design was completely randomized in a 2 x11 factorial scheme (period of bunch formation x number of leaves at flowering), 6-16 leaves at flowering in two periods of bunch formation with six replicates. In Period 1, flowering occurred at 04/15/13 and in Period 2 at 01/07/14, although in Period 1, bunch mass was higher and in Period 2, higher average maximum and minimum daily temperatures, precipitation and radiation were observed. Regardless of formation period, the number of leaves at flowering affected bunch mass, which ranged from 18 to 23 kg plant-1. Defoliation affected the size of fruits of hand 1 and last hand of the bunch, but not the variability in fruit size due to the position the fruit occupies in the bunch and physicochemical characteristics.

Peso ao nascer é uma informação essencial nos estudos de programação fetal e, em geral, obtida retrospectivamente. No Sistema de Informações sobre Nascidos Vivos (SINASC), peso ao nascer é uma informação válida, mas nem sempre acessível. Objetivou-se estabelecer um algoritmo para seleção da fonte de dados de maior confiabilidade do peso ao nascer na ausência da informação do SINASC. No estudo seccional de estudantes de 6-14 anos, Niterói, Rio de Janeiro, Brasil, 2010, peso ao nascer foi coletado por meio de questionário de autopreenchimento, entrevista, prontuários do Programa Médico de Família (PMF), além do SINASC. Foram calculados coeficientes de correlação intraclasse (CCI) e diferenças das médias de peso ao nascer. CCIs variaram de 0,90 a 0,99. Todas as fontes apresentaram médias de peso ao nascer maiores do que SINASC, considerando-se aceitáveis diferenças até 100g. O peso ao nascer é registrado no nascimento (SINASC) ou próximo deste (PMF) e, na ausência dessas fontes, a lembrança do peso ao nascer de 6-14 anos após o nascimento é uma opção confiável. Para complementar a informação sobre peso ao nascer na ausência do SINASC, recomenda-se a seguinte ordenação: PMF, entrevista e questionário.
